TOPLINE:

Metformin cuts the risk for diabetic nephropathy (DN) and major kidney and cardiovascular events in patients with newly diagnosed type 2 diabetes (T2D) across various renal function states.

METHODOLOGY:

Metformin is a first-line treatment in US and South Korean T2D management guidelines, except for patients with advanced chronic kidney disease (CKD) (stage, ≥ 4; estimated glomerular filtration rate [eGFR], < 30).

The study used data from the databases of three tertiary hospitals in South Korea to assess the effect of metformin on long-term renal and cardiovascular outcomes across various renal function states in patients with newly diagnosed T2D.

Four groups of treatment-control comparative cohorts were identified at each hospital: Patients who had not yet developed DN at T2D diagnosis (mean age in treatment and control cohorts, 61-65 years) and those with reduced renal function (CKD stages 3A, 3B, and 4).

Patients who continuously received metformin after T2D diagnosis and beyond the observation period were 1:1 propensity score matched with controls who were prescribed oral hypoglycemic agents other than metformin.

Primary outcomes were net major adverse cardiovascular events including strokes (MACEs) or in-hospital death and a composite of major adverse kidney events (MAKEs) or in-hospital death.

TAKEAWAY:

Among patients without DN at T2D diagnosis, the continuous use of metformin vs other oral hypoglycemic agents was associated with a lower risk for:

Overt DN (incidence rate ratio [IRR], 0.82; 95% CI, 0.71-0.95),

MACEs (IRR, 0.76; 95% CI, 0.64-0.92), and

MAKEs (IRR, 0.45; 95% CI, 0.33-0.62).

Compared with non-metformin or discontinued metformin use, the continuous use of metformin was associated with a lower risk for MACE across CKD stages 3A (IRR, 0.70; 95% CI, 0.57-0.87), 3B (IRR, 0.83; 95% CI, 0.74-0.93), and 4 (IRR, 0.71; 95% CI, 0.60-0.85).

Similarly, the risk for MAKE was lower among continuous metformin users than in nonusers or discontinuous metformin users across CKD stage 3A (IRR, 0.39; 95% CI, 0.35-0.43), 3B (IRR, 0.44; 95% CI, 0.40-0.48), and 4 (IRR, 0.45; 95% CI, 0.39-0.51).

IN PRACTICE:

“The significance of the current study is highlighted by its integration of real-world clinical data, which encompasses patients diagnosed with CDK4 [eGRF, 15-29 mL/min/1.73 m2], a group currently considered contraindicated,” the authors wrote.

SOURCE:

The study, led by Yongjin Yi, MD, PhD, Department of Internal Medicine, Dankook University College of Medicine, Cheonan-si, Republic of Korea, was published in Scientific Reports.

LIMITATIONS:

There may be a possibility of selection bias because of the retrospective and observational nature of this study. Despite achieving a 1:1 propensity score matching to address the confounding factors, some variables, such as serum albumin and A1c levels, remained unbalanced after matching. The paper did not include observation length or patient numbers, but in response to an email query from Medscape, Yi notes that in one hospital, the mean duration of observation for the control and treatment groups was about 6.5 years, and the total number in the treatment groups across data from three hospitals was 11,675, with the same number of matched controls.

DISCLOSURES:

This study was supported by a Young Investigator Research Grant from the Korean Society of Nephrology, a grant from the Seoul National University Bundang Hospital Research Fund, and the Bio&Medical Technology Development Program of the National Research Foundation funded by the Korean government. The authors disclosed no competing interests.

Bone-modifying agents — most notably denosumab — are often prescribed to prevent skeletal-related complications in patients with metastatic castration-sensitive prostate cancer, but the drugs are not recommended for this indication and can lead to severe toxicities.

How much does Medicare spend each year on non-recommended bone therapy?

The answer, according to a new analysis in JCO Oncology Practice, is more than $44 million, with about $43 million coming from denosumab alone.

Overall, this study found that “the Medicare program pays tens of millions of dollars each year” for bone-modifying agents in patients with metastatic castration-sensitive prostate cancer, “which is not effective and may cause side effects,” lead author Aaron Mitchell, MD, MPH, a medical oncologist at Memorial Sloan Kettering Cancer Center, New York City, and colleagues concluded.

“These findings suggest reducing bone agent overuse could be a rare healthcare ‘win-win.’ Lower costs AND improved patient outcomes,” tweeted Dr. Mitchell. “If I were a payer, I’d be paying attention!”
 

In Prostate Cancer, Bone-Modifying Drug Indications Vary

Bone-modifying drugs are indicated for some patients with prostate cancer.

The American Society of Clinical Oncology has endorsed guidelines that recommend the use of denosumab in men with nonmetastatic prostate cancer at high risk for fracture while taking androgen deprivation therapy.

Among men with metastatic castration-resistant prostate cancer, guidelines also recommend zoledronic acid or denosumab for preventing or delaying skeletal-related events, such as pathologic fractures and spinal cord compression.

For patients with metastatic castration-sensitive disease, however, the bone-modifying agents show no benefit in preventing skeletal-related events and are not recommended for that indication.

In this population, “treatment with bone agents results only in avoidable toxicity and financial cost,” Dr. Mitchell tweeted. In its higher-dose formulation, denosumab comes with a price tag of approximately $40,000 per year in the United States.

An earlier study from Dr. Mitchell and colleagues revealed that the use of bone-modifying drugs to prevent skeletal events in metastatic castration-sensitive prostate cancer is common.

To better understand the costs associated with this inappropriate use, the researchers reviewed Surveillance, Epidemiology, and End Results Program Medicare data from 2011 to 2015. The team identified the frequency and number of doses of zoledronic acid and denosumab prescribed against recommendations in the metastatic castration-sensitive setting, making sure to distinguish between the use of denosumab to prevent osteoporotic fractures (appropriate use) and to prevent skeletal-related events (non-recommended use).

The team found that, among 2627 patients with metastatic castration-sensitive prostate cancer, 42% received at least one dose of denosumab and 18% received at least one dose of zoledronic acid.

The authors also found that unnecessary use of these drugs increased over time — with a little over 17% of patients receiving zoledronic acid between 2007 and 2009 and just over 28% receiving either denosumab (20.3%) or zoledronic acid (8.4%) from 2012 to 2015.

The annual costs to Medicare from non-recommended prescribing came to $44,105,041 for both agents, with the costs associated with denosumab representing the lion’s share at $43,303,078.

Non-recommended use of these agents also came with adverse events, such as femur fracture and hypocalcemia, which cost an estimated $758,450 to treat annually — $682,865 for denosumab and $75,585 for zoledronic acid.

The study focused on the Medicare-age population, which means the estimates are conservative. “Denosumab overuse for younger patients with castration-sensitive prostate cancer would add substantially to this total,” the authors wrote.

“This study contributes new evidence of overuse in the metastatic castrate-sensitive prostate cancer setting, which I must admit reflects my clinical experience in seeing patients for second opinions who are treated in the community,” said Samuel U. Takvorian, MD, of the Division of Hematology and Oncology, Perelman School of Medicine, Philadelphia, who wasn’t involved in the research. “While there are some circumstances in which one would consider using a bone-modifying agent in the metastatic castrate-sensitive prostate cancer setting, most [of these] men don’t need them upfront.”
 

Why Is the Overuse Happening?

One reason for the inappropriate use of bone-modifying drugs could be confusion surrounding the recommendations because the drugs are recommended for some patients with prostate cancer.

Michael R. Laurent, MD, PhD, of Imelda Hospital, Bonheiden, Belgium, explained that the use of bone-modifying drugs is, paradoxically, often overlooked in settings where they are recommended — when patients have an elevated risk for osteoporosis or fracture.

“Guidelines are quite unequivocal in their recommendations to prevent osteoporosis in mostly older men who receive androgen deprivation therapy,” but “I think there is significant undertreatment” in these patients, Dr. Laurent told this news organization.

However, the recommendation for patients at risk for osteoporosis or bone fracture calls for less intense regimens, which may include lower-dose denosumab, administered once every 6 months, zoledronic acid, given yearly, or another lower potency agent, such as oral alendronate weekly, explained Philip J. Saylor, MD, an attending physician at Massachusetts General Hospital and assistant professor at Harvard Medical School, Boston.

Meanwhile, “monthly high-intensity therapy to prevent skeletal events should be reserved specifically for bone metastatic castration-resistant prostate cancer for more than just cost reasons,” Dr. Saylor said.

When it comes to the higher dose, monthly therapy in castration-sensitive prostate cancer, “we have no evidence that it is beneficial,” he said, adding that “when the prostate cancer itself is well controlled by hormonal therapy, there just aren’t very many pathologic fractures or other bone complications.”

Alongside possible confusion over the recommendations, many physicians also likely don’t know how much denosumab costs.

“In our recent physician interview study, we did find that most physicians were very much unaware of the cost of this drug, or the cost difference between denosumab and zoledronic acid, so I do think that lack of cost awareness is a factor,” Dr. Mitchell said.

Part of the reason may be how Medicare covers these agents. Typically, Medicare would not cover non-recommended indications, but “in this case, Medicare coverage is broader and includes both the guideline-recommended and non-recommended uses,” Dr. Mitchell explained.

However, the authors also identified a more cynical reason for non-recommended prescribing — promotional payments from drug makers to physicians.

In another recent paper, Dr. Mitchell said he found about “30% of doctors treating prostate cancer had received payments from Amgen for Xgeva [denosumab] promotion during the last year.”

These payments appeared to influence non-recommended prescribing: Among patients whose doctor had not received payments, 31.4% received non-recommended denosumab, which increased to nearly 50% of patients among doctors who had received payments.

Dr. Mitchell suggested a few ways to help curb inappropriate prescribing.

Medicare could, for instance, change its coverage policy to include only the recommended uses of these agents, Dr. Mitchell said.

More physician education would be another solution. “I think that physician education would be one ‘bottom-up’ approach that could work,” Dr. Mitchell added.

Dr. Mitchell, Dr. Takvorian, and Dr. Saylor had no disclosures to report. Dr. Laurent has received lecture and consultancy fees from Alexion, AM Pharma, Amgen, Galapagos, Kyowa Kirin, Menarini, Orifarm, Pharmanovia, Takeda, UCB, and Will Pharma.

These payments appeared to influence non-recommended prescribing: Among patients whose doctor had not received payments, 31.4% received non-recommended denosumab, which increased to nearly 50% of patients among doctors who had received payments.

Dr. Mitchell suggested a few ways to help curb inappropriate prescribing.

Medicare could, for instance, change its coverage policy to include only the recommended uses of these agents, Dr. Mitchell said.

More physician education would be another solution. “I think that physician education would be one ‘bottom-up’ approach that could work,” Dr. Mitchell added.

Dr. Mitchell, Dr. Takvorian, and Dr. Saylor had no disclosures to report. Dr. Laurent has received lecture and consultancy fees from Alexion, AM Pharma, Amgen, Galapagos, Kyowa Kirin, Menarini, Orifarm, Pharmanovia, Takeda, UCB, and Will Pharma.

TOPLINE:

More than a billion children, adolescents, and adults are living with obesity, globally, with rates of obesity among children and adolescents quadrupling between 1990 and 2022.

Obesity rates nearly tripled among adult men and more than doubled among women during the time period, according to results from a collaboration between the NCD Risk Factor Collaboration and the World Health Organization (WHO).

The rates of being underweight have meanwhile declined, making obesity now the most common form of malnutrition in most regions.

METHODOLOGY:

In this global analysis, the authors evaluated 3663 population-based studies conducted in 200 countries and territories, with data on 222 million participants in the general population, including height and weight.

Trends were established according to categories of body mass index (BMI) in groups of adults aged 20 years or older, representing 150 million individuals, and 63 million school-aged children and adolescents aged 5-19 years, spanning from 1990 to 2022.

Assessments of adults focus on the individual and combined prevalence of underweight (BMI < 18.5 kg/m²) and obesity (BMI ≥ 30 kg/m²).

For school-aged children and adolescents, assessments were for thinness (BMI < 2 standard deviation [SD] below the median of the WHO growth reference) and obesity (BMI > 2 SD above the median).

TAKEAWAY:

The combined prevalence of obesity as well as underweight increased over the study period in most countries for women (162 countries, 81%) and men (140 countries, 70%), with increases driven by increases in obesity in nearly all countries, while underweight or thinness rates decreased.

In 2022, obesity rates were higher than underweight in 177 countries (89%) for women and 145 countries (73%) for men.

Likewise, among school-aged children and adolescents, obesity in 2022 was more prevalent than thinness among girls in 130 countries (67%) and boys in 125 countries (63%), while thinness was more prevalent in only 18% and 21% of the countries, respectively.

In 2022, the combined prevalence of underweight and obesity was highest in island nations in the Caribbean and Polynesia and Micronesia, as well as in countries in the Middle East and North Africa.

Among school-aged children, the countries with the highest combined prevalence of underweight and obesity were Polynesia and Micronesia and the Caribbean for both sexes and Chile and Qatar for boys.

The prevalence of obesity surpassed 60% among women in eight countries (4%) and men in six countries (3%), all in Polynesia and Micronesia.

In the United States, the obesity rate increased from 21.2% in 1990 to 43.8% in 2022 for women and from 16.9% to 41.6% in 2022 for men.

As of 2022, the prevalence of obesity in the United States ranked 36th highest in the world for women and 10th highest in the world for men.

IN PRACTICE:

“It is very concerning that the epidemic of obesity that was evident among adults in much of the world in 1990 is now mirrored in school-aged children and adolescents,” senior author Majid Ezzati, PhD, of Imperial College of London, said in a press statement.

“At the same time, hundreds of millions are still affected by undernutrition, particularly in some of the poorest parts of the world,” he said. “To successfully tackle both forms of malnutrition, it is vital we significantly improve the availability and affordability of healthy, nutritious foods.”

Tedros Adhanom Ghebreyesus, PhD, WHO Director-General, added in the press statement that “this new study highlights the importance of preventing and managing obesity from early life to adulthood, through diet, physical activity, and adequate care, as needed.

“Getting back on track to meet the global targets for curbing obesity will take the work of governments and communities, supported by evidence-based policies from WHO and national public health agencies,” he said.

“Importantly, it requires the cooperation of the private sector, which must be accountable for the health impacts of their products.”

The study was published on February 29, 2024, in The Lancet. The study was conducted by the NCD Risk Factor Collaboration and the WHO.

LIMITATIONS:

Data differences in countries included that some had limited data and three had none, requiring some estimates to be formed using data from other countries. Data availability was also lower among the youngest and oldest patients, increasing uncertainty of data in those age groups. In addition, data from health surveys can be subject to error, and BMI can be an imperfect measure of the extent or distribution of body fat.

DISCLOSURES:

The study was funded by UK Medical Research Council, UK Research and Innovation, and the European Commission.

TOPLINE:

People with diabetes who live in small towns in the United States experience higher rates of complications than those living in cities and remote areas.

METHODOLOGY:

Retrospective cohort study using the OptumLabs Data Warehouse used a deidentified data set of US commercial and Medicare Advantage beneficiaries including 2,901,563 adults with diabetes between 2012 and 2021.

Overall, 2.6% lived in remote areas (population < 2500), 14.1% in small towns (2500-50,000), and 83.3% in cities (> 50,000).

Multivariable analysis adjusted for age, sex, health plan type, index year, diabetes type, baseline comorbidities, and medication use.

TAKEAWAY:

Relative to people living in cities, people in remote areas had significantly greater risks for myocardial infarction (hazard ratio, 1.06) and revascularization (1.04) but lower risks for hypoglycemia (0.90) and stroke (0.91).

Compared with cities, people living in small towns had significantly more hyperglycemia (1.06), hypoglycemia (1.15), end-stage kidney disease (1.04), myocardial infarction (1.10), heart failure (1.05), amputation (1.05), other lower-extremity complications (1.02), and revascularization (1.05), but a lower risk for stroke (0.95).

Compared with small towns, people living in remote areas had lower risks for hyperglycemia (0.85), hypoglycemia (0.92), and heart failure (0.94).

No geographic differences were found for retinopathy or atrial fibrillation/flutter.

The results didn’t differ significantly when the 2.5% overall with type 1 diabetes were removed from the dataset.

IN PRACTICE:

“While more research is needed to better understand the underlying causes of disparate diabetes outcomes along the rural-urban continuum, this study establishes the foundational differences to guide improvement efforts and helps to identify complications with the greatest disparities to which policy interventions may be targeted.”

SOURCE:

The study was conducted by Kyle Steiger, MD, Internal Medicine Residency, Mayo Clinic, Rochester, Minnesota, and colleagues, and published February 22 in Diabetes Care.

LIMITATIONS:

Claims data were from a single national health insurance provider that administers multiple private and Medicare Advantage health plans with disproportionate representation of urban populations and without people who have Medicaid or traditional Medicare fee-for-service or who are without insurance (and would be expected to have higher complication rates). There were no data on race/ethnicity. Potential for residual confounding.

DISCLOSURES:

This study was funded by the National Institute of Diabetes and Digestive and Kidney Diseases. Dr. Steiger had no disclosures.

TOPLINE:

Continued denosumab treatment is associated with a lower risk for diabetes in adults with osteoporosis older than 65 years, found a large-scale cohort study in Taiwan.

METHODOLOGY:

• Denosumab, used in osteoporosis treatment, has been suggested to improve glycemic parameters, but clinical evidence of its effects on diabetes risk is limited and inconsistent.
• Using data from Taiwan’s National Health Insurance Research Database (NHIRD), the study asked if continued denosumab treatment (60 mg) for osteoporosis reduced the risk for diabetes compared to those who discontinued denosumab.
• Researchers included all new users of denosumab between 2012 and 2019 who had no prior history of malignant neoplasms, Paget disease, or diabetes requiring antidiabetic medication.
• Patients in the treatment group (n = 34,255), who received a second dose of denosumab within 225 days, were 1:1 propensity matched with a control group (n = 34,255) of patients who had discontinued denosumab after the first dose.
• The 68,510 patients (mean age, 77.7 years; 84.3% women) were followed up for a mean of 1.9 years. The primary outcome was new-onset diabetes that required treatment with any antidiabetic drug.

TAKEAWAY:

• Continued denosumab treatment vs its discontinuation was associated with a lower risk for incident diabetes (hazard ratio [HR], 0.84; 95% CI, 0.78-0.90).
• In patients aged 65 years or older who were on continued treatment of denosumab, the risk for diabetes was lower (HR, 0.80; 95% CI, 0.75-0.85) but not among those younger than 65 years.
• A reduced risk for diabetes with continued denosumab treatment was observed in both men (HR, 0.85; 95% CI, 0.73-0.97) and women (HR, 0.81; 95% CI, 0.76-0.86).
• Lower diabetes risk with continued denosumab treatment was observed regardless of comorbidities, such as dyslipidemia, hypertension, ischemic heart disease, or kidney failure.

IN PRACTICE:

“Given the high osteoporosis prevalence, the extensive use of antiosteoporosis medications, and the negative effect of diabetes on both patient health and healthcare system burdens in the global aging population, our findings possess substantial clinical and public health significance,” the authors wrote.

SOURCE:

This study was led by Huei-Kai Huang, MD, Department of Family Medicine and Department of Medical Research, Hualien Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation, Hualien, Taiwan, and published online in JAMA Network Open.

LIMITATIONS:

The research used claims-based data, so some clinical details, such as lifestyle, substance use, prediabetes weight status, and laboratory results, were not included. Owing to the anonymity policy of the NHIRD, patients could not be directly evaluated to validate incident diabetes. The study included the Taiwanese population, so the findings may not be generalizable to other populations. In Taiwan, the threshold for reimbursement of initiating denosumab treatment for osteoporosis includes below-normal bone density scores and a hip or vertebral fracture.

DISCLOSURES:

This study was supported by grants from the National Science and Technology Council of Taiwan and the National Health Research Institutes of Taiwan and a grant from the Buddhist Tzu Chi Medical Foundation. The corresponding author and a coauthor disclosed receiving funds from Amgen, Novartis, Pfizer, Sanofi, Takeda, and AbbVie, all outside the submitted work.

TOPLINE:

The risk of developing gynecologic cancer is lower in women with hyperthyroidism than in those without it, found a large study. 

METHODOLOGY:

• Thyroid disease and altered thyroid hormone expression can affect ovulation, endometrial physiology, and estrogen levels, but studies of the association with gynecologic cancer risk have conflicting results.
• This population-based cohort study used data from the Taiwan National Health Insurance Research Database to identify women (mean age, 44 years) who were diagnosed with thyroid disease between January 2000 and December 2018.
• Propensity scores were used to pair 296,872 women with hyperthyroidism and 44,852 with hypothyroidism in a 1:1 ratio with an equal number of individuals without thyroid disorders.
• The cohort was followed up from the date of first diagnosis of hypothyroidism or hyperthyroidism until the diagnosis of gynecologic cancers (endometrial cancer, uterine corpus cancer, and ovarian cancer), death, or the end of 2018.

TAKEAWAY:

• Women with hyperthyroidism had a lower risk for all gynecologic cancers than those without hyperthyroidism (adjusted hazard ratio [aHR], 0.86; P = .0084).
• The risk of developing gynecologic cancer was lower among women with hyperthyroidism aged 20-40 years (aHR, 0.72; P = .0043) but not among those aged > 40 years.
• The reduced risk for gynecologic cancers associated with hyperthyroidism persisted even beyond 6 years of follow-up (aHR, 0.75; P < .001).
• A trend toward a slightly increased risk for gynecologic cancer was observed among women with hypothyroidism; however, the association was not statistically significant.

IN PRACTICE:

The findings may alert oncologists and healthcare decision-makers toward gynecologic cancer trends and prompt further research to understand the mechanism by which thyroid hormone regulates reproductive function, the authors noted.

SOURCE:

This study was led by John Hang Leung from the Ditmanson Medical Foundation Chia-Yi Christian Hospital, Chiayi, Taiwan, and published online in Scientific Reports.

LIMITATIONS:

The study data were obtained from administrative claims databases, so there is a possibility of underestimation or overestimation. Lifestyle factors such as obesity and alcoholism are difficult to measure, so the risk for gynecologic cancers linked to thyroid dysfunction may have been underestimated. Furthermore, because of nonavailability of laboratory data, thyroid hormone status at diagnosis could not be linked to gynecological cancer risk.

DISCLOSURES:

This study was supported by An-Nan Hospital, China Medical University, Tainan, Taiwan. The authors declared no financial interests or conflicts related to the study.

The US Food and Drug Administration (FDA) announced the removal of the endocrine-disrupting chemicals (EDCs) per- and polyfluoroalkyl substances (PFAS) from food packaging.

Issued on February 28, 2024, “this means the major source of dietary exposure to PFAS from food packaging like fast-food wrappers, microwave popcorn bags, take-out paperboard containers, and pet food bags is being eliminated,” the FDA said in a statement.

In 2020, the FDA had secured commitments from manufacturers to stop selling products containing PFAS used in the food packaging for grease-proofing. “Today’s announcement marks the fulfillment of these voluntary commitments,” according to the agency.

PFAS, a class of thousands of chemicals also called “forever chemicals” are widely used in consumer and industrial products. People may be exposed via contaminated food packaging (although perhaps no longer in the United States) or occupationally. Studies have found that some PFAS disrupt hormones including estrogen and testosterone, whereas others may impair thyroid function.
 

Endocrine Society Report Sounds the Alarm About PFAS and Others

The FDA’s announcement came just 2 days after the Endocrine Society issued a new alarm about the human health dangers from environmental EDCs including PFAS in a report covering the latest science.

“Endocrine disrupting chemicals” are individual substances or mixtures that can interfere with natural hormonal function, leading to disease or even death. Many are ubiquitous in the modern environment and contribute to a wide range of human diseases.

The new report Endocrine Disrupting Chemicals: Threats to Human Health was issued jointly with the International Pollutants Elimination Network (IPEN), a global advocacy organization. It’s an update to the Endocrine Society’s 2015 report, providing new data on the endocrine-disrupting substances previously covered and adding four EDCs not discussed in that document: Pesticides, plastics, PFAS, and children’s products containing arsenic.

At a briefing held during the United Nations Environment Assembly meeting in Nairobi, Kenya, last week, the new report’s lead author Andrea C. Gore, PhD, of the University of Texas at Austin, noted, “A well-established body of scientific research indicates that endocrine-disrupting chemicals that are part of our daily lives are making us more susceptible to reproductive disorders, cancer, diabetes, obesity, heart disease, and other serious health conditions.”

Added Dr. Gore, who is also a member of the Endocrine Society’s Board of Directors, “These chemicals pose particularly serious risks to pregnant women and children. Now is the time for the UN Environment Assembly and other global policymakers to take action to address this threat to public health.”

While the science has been emerging rapidly, global and national chemical control policies haven’t kept up, the authors said. Of particular concern is that EDCs behave differently from other chemicals in many ways, including that even very low-dose exposures can pose health threats, but policies thus far haven’t dealt with that aspect.

Moreover, “the effects of low doses cannot be predicted by the effects observed at high doses. This means there may be no safe dose for exposure to EDCs,” according to the report.

Exposures can come from household products, including furniture, toys, and food packages, as well as electronics building materials and cosmetics. These chemicals are also in the outdoor environment, via pesticides, air pollution, and industrial waste.

“IPEN and the Endocrine Society call for chemical regulations based on the most modern scientific understanding of how hormones act and how EDCs can perturb these actions. We work to educate policy makers in global, regional, and national government assemblies and help ensure that regulations correlate with current scientific understanding,” they said in the report.
 

New Data on Four Classes of EDCs

Chapters of the report summarized the latest information about the science of EDCs and their links to endocrine disease and real-world exposure. It included a special section about “EDCs throughout the plastics life cycle” and a summary of the links between EDCs and climate change.

The report reviewed three pesticides, including the world’s most heavily applied herbicide, glycophosphate. Exposures can occur directly from the air, water, dust, and food residues. Recent data linked glycophosphate to adverse reproductive health outcomes.

Two toxic plastic chemicals, phthalates and bisphenols, are present in personal care products, among others. Emerging evidence links them with impaired neurodevelopment, leading to impaired cognitive function, learning, attention, and impulsivity.

Arsenic has long been linked to human health conditions including cancer, but more recent evidence finds it can disrupt multiple endocrine systems and lead to metabolic conditions including diabetes, reproductive dysfunction, and cardiovascular and neurocognitive conditions.

The special section about plastics noted that they are made from fossil fuels and chemicals, including many toxic substances that are known or suspected EDCs. People who live near plastic production facilities or waste dumps may be at greatest risk, but anyone can be exposed using any plastic product. Plastic waste disposal is increasingly problematic and often foisted on lower- and middle-income countries.
 

‘Additional Education and Awareness-Raising Among Stakeholders Remain Necessary’

Policies aimed at reducing human health risks from EDCs have included the 2022 Plastics Treaty, a resolution adopted by 175 countries at the United Nations Environmental Assembly that “may be a significant step toward global control of plastics and elimination of threats from exposures to EDCs in plastics,” the report said.

The authors added, “While significant progress has been made in recent years connecting scientific advances on EDCs with health-protective policies, additional education and awareness-raising among stakeholders remain necessary to achieve a safer and more sustainable environment that minimizes exposure to these harmful chemicals.”

The document was produced with financial contributions from the Government of Sweden, the Tides Foundation, Passport Foundation, and other donors.

Emerging evidence suggests that oral health, often overlooked by clinicians, is closely connected with overall health — and this connection has important consequences for individuals with type 2 diabetes (T2D). While most studies are observational and can’t prove cause and effect, the associations are robust enough for researchers to conclude that the connection is real.

Endocrinologists and other specialists, as well as primary care physicians, should ask about oral health, if not look in the mouth directly, experts say. “One of the most important things to ask people with diabetes is when their last dental visit was and if they have a follow-up,” said Robert Gabbay, MD, PhD, Chief Scientific and Medical Officer of the American Diabetes Association (ADA). The ADA advocates for attention to oral health through its 2024 standards of care.

Systemic Impact

“Periodontitis is a probable risk factor for various problems connected to the cardiovascular, pulmonary, endocrine, musculoskeletal, central nervous, and reproductive systems,” wrote the authors of a recent review on the effects of periodontitis on major organ systems. While not specific to the diabetes connection, the review pinpoints some of the latest evidence that “oral health affects overall health, and…dental health should never be considered a distinct, remote, and lower significant part of health.”

In line with this perspective, and looking specifically at T2D, a recent study of more than 17,000 patients with T2D participating in a screening program in Korea found that periodontitis and an increased number of teeth with cavities were independent risk factors for cerebral or myocardial infarction (adjusted hazard ratios, 1.17 and 1.67, respectively).

Dental disease and poor oral hygiene were also associated with an increased risk for heart failure among people with T2D in a large cohort study, and the authors suggested that managing oral health may prevent heart failure development.

A recent review suggested that periodontitis exacerbates and promotes the progression of chronic kidney disease, a disorder that affects 1 in 3 people with diabetes.

Studies also have shown that diabetes is associated with cognitive decline, and a review of oral health and dementia progression concluded, “collectively, experimental findings indicate that the connection between oral health and cognition cannot be underestimated.”

Bidirectional Effects

Research has shown that the association between periodontal disease and T2D is likely bidirectional, although there is little awareness of this two-way relationship among patients and providers.

A recent review of this bidirectional relationship focused on microvascular complications, oral microbiota, pro- and anti-inflammatory factors in T2D and periodontal disease and concluded that “these two diseases require specific/complementary therapeutic solutions when they occur in association, with new clinical trials and epidemiological research being necessary for better control of this interdependent pathogenic topic.”

Yet an Australian study showed that 54% of 241 participants in a survey never received any information regarding the bidirectional relationship between periodontal disease and diabetes and lacked understanding of the association.

What’s the Mechanism?

How does T2D affect the teeth and vice versa? “Basically, people with T2D have high blood sugar, and the sugar comes out in the saliva and that promotes bacterial growth in the mouth and plaque formation on the teeth and gum disease,” Samir Malkani, MD, clinical chief of endocrinology and diabetes at UMass Chan School of Medicine in Worcester, Massachusetts, told this news organization.

“Patients get gingivitis, they get periodontitis, and since the gums and the jaw are a single unit, if the gum disease gets very severe, then there’s loss of jawbone and the teeth could fall out,” he said. There’s also inflammation in the mouth, and “when you have generalized inflammation, it affects the whole body.”

Recent research in Europe suggested that “although the mechanisms behind these associations are partially unclear, poor oral health is probably sustaining systemic inflammation.” Common oral infections, periodontal disease, and cavities are associated with inflammatory metabolic profiles related to an increased risk for cardiometabolic diseases, and they predict future adverse changes in metabolic profiles, according to the authors.

Awareness, Accessibility, Collaboration

Despite the evidence, the connection between oral health and diabetes (any type) is not front of mind with clinicians or patients, Dr. Malkani said. He pointed to a systematic review that included 28 studies of close to 28,000 people in 14 countries. The review found that people with diabetes have “inadequate oral health knowledge, poor oral health attitudes, and fewer dental visits, [and] rarely receive oral health education and dental referrals from their care providers.”

Social determinants of health have a “huge impact” on whether people will develop T2D and its related complications, including poor oral health, according to the National Clinical Care Commission Report presented to the US Congress in 2022. The commission was charged with making recommendations for federal policies and programs that could more effectively prevent and control diabetes and its complications.

The commission “approached its charge through the lens of a socioecological and an expanded chronic care model,” the report authors wrote. “It was clear that diabetes in the US cannot simply be viewed as a medical or healthcare problem but also must be addressed as a societal problem that cuts across many sectors, including food, housing, commerce, transportation, and the environment.”

Diabetes also is associated with higher dental costs, another factor affecting an individual’s ability to obtain care.

A recent questionnaire-based study from Denmark found that people with T2D were more likely than those without diabetes to rate their oral health as poor, and that the risk for self-rated poor oral health increased with lower educational attainment. Highest educational attainment and disposable household income were indicators of a high socioeconomic position, and a lower likelihood of rating their oral health as poor, again pointing out inequities.

The authors concluded that “diabetes and dental care providers should engage in multidisciplinary collaboration across healthcare sectors to ensure coherent treatment and management of diabetes.”

But such collaborations are easier said than done. “One of the challenges is our fragmented health system, where oral health and medical care are separate,” Dr. Gabbay said.

For the most part, the two are separate, Dr. Malkani agreed. “When we’re dealing with most complications of diabetes, like involvement of the heart or eyes or kidneys, we can have interdisciplinary care — everyone is within the overall discipline of medicine, and if I refer to a colleague in ophthalmology or a cardiologist or a vascular surgeon, they can all be within the same network from an insurance point of view, as well.”

But for dental care, referrals are interprofessional, not interdisciplinary. “I have to make sure that the patient has a dentist because dentists are usually not part of medical networks, and if the patient doesn’t have dental insurance, then cost and access can be a challenge.”

A recent systematic review from Australia on interprofessional education and interprofessional collaborative care found that more than a third of medical professionals were “ignorant” of the relationship between oral health and T2D. Furthermore, only 30% reported ever referring their patients for an oral health assessment. And there was little, if any, interprofessional collaborative care between medical and dental professionals while managing patients with T2D.

Treat the Teeth

“We always talk to our T2D patients about the importance of getting an eye exam, a foot exam, and a kidney test,” Dr. Malkani said. “But we also need to make sure that they’re going to the dentist. Normally, people get their teeth cleaned twice a year. But if you have diabetes and poor oral health, you might need to get your teeth cleaned every three months, and insurance often will pay for that.”

Furthermore, in keeping with the bidirectional connection, treating periodontitis can help glycemic control. The authors of a 2022 update of a Cochrane review on treating periodontitis for glycemic control wrote that they “doubled the number of included studies and participants” from the 2015 update to 35 studies randomizing 3249 participants to periodontal treatment or control. This “led to a change in our conclusions about the primary outcome of glycemic control and in our level of certainty in this conclusion.”

“We now have moderate‐certainty evidence that periodontal treatment using subgingival instrumentation improves glycemic control in people with both periodontitis and diabetes by a clinically significant amount when compared to no treatment or usual care. Further trials evaluating periodontal treatment vs no treatment/usual care are unlikely to change the overall conclusion reached in this review.”

“Dentists also have a responsibility,” Dr. Malkani added. “If they see someone with severe gum disease or cavities, especially at a younger age, they need to tell that person to get their blood sugar checked and make sure they don’t have T2D.”

In fact, a recent review found that complications of T2D such as xerostomia and periodontal problems adversely affect well-being, and that “dentists can play an essential role in the awareness of diabetic patients about these problems and improve their quality of life.”

Key Stats

The US Centers for Disease Control and Prevention highlighted these facts about diabetes and oral health:

• Adults aged 20 years or older with diabetes are 40% more likely to have untreated cavities than similar adults without diabetes.
• About 60% of US adults with diabetes had a medical visit in the past year but no dental visit.
• Expanding healthcare coverage for periodontal treatment among people with diabetes could save each person about $6000 (2019 US dollars) over their lifetimes.
• Adults aged 50 years or older with diabetes lack functional dentition (have fewer than 20 teeth) 46% more often and have severe tooth loss (eight or fewer teeth) 56% more often than those without diabetes.
• Adults aged 50 years or older with diabetes are more likely to report that they have a hard time eating because of dental problems.
• Annual dental expenditures for an adult with diabetes are $77 (2017 US dollars) higher than for an adult without diabetes. This cost translates to $1.9 billion for the United States.

Emerging evidence suggests that oral health, often overlooked by clinicians, is closely connected with overall health — and this connection has important consequences for individuals with type 2 diabetes (T2D). While most studies are observational and can’t prove cause and effect, the associations are robust enough for researchers to conclude that the connection is real.

Endocrinologists and other specialists, as well as primary care physicians, should ask about oral health, if not look in the mouth directly, experts say. “One of the most important things to ask people with diabetes is when their last dental visit was and if they have a follow-up,” said Robert Gabbay, MD, PhD, Chief Scientific and Medical Officer of the American Diabetes Association (ADA). The ADA advocates for attention to oral health through its 2024 standards of care.

Systemic Impact

“Periodontitis is a probable risk factor for various problems connected to the cardiovascular, pulmonary, endocrine, musculoskeletal, central nervous, and reproductive systems,” wrote the authors of a recent review on the effects of periodontitis on major organ systems. While not specific to the diabetes connection, the review pinpoints some of the latest evidence that “oral health affects overall health, and…dental health should never be considered a distinct, remote, and lower significant part of health.”

In line with this perspective, and looking specifically at T2D, a recent study of more than 17,000 patients with T2D participating in a screening program in Korea found that periodontitis and an increased number of teeth with cavities were independent risk factors for cerebral or myocardial infarction (adjusted hazard ratios, 1.17 and 1.67, respectively).

Dental disease and poor oral hygiene were also associated with an increased risk for heart failure among people with T2D in a large cohort study, and the authors suggested that managing oral health may prevent heart failure development.

A recent review suggested that periodontitis exacerbates and promotes the progression of chronic kidney disease, a disorder that affects 1 in 3 people with diabetes.

Studies also have shown that diabetes is associated with cognitive decline, and a review of oral health and dementia progression concluded, “collectively, experimental findings indicate that the connection between oral health and cognition cannot be underestimated.”

Bidirectional Effects

Research has shown that the association between periodontal disease and T2D is likely bidirectional, although there is little awareness of this two-way relationship among patients and providers.

A recent review of this bidirectional relationship focused on microvascular complications, oral microbiota, pro- and anti-inflammatory factors in T2D and periodontal disease and concluded that “these two diseases require specific/complementary therapeutic solutions when they occur in association, with new clinical trials and epidemiological research being necessary for better control of this interdependent pathogenic topic.”

Yet an Australian study showed that 54% of 241 participants in a survey never received any information regarding the bidirectional relationship between periodontal disease and diabetes and lacked understanding of the association.

What’s the Mechanism?

How does T2D affect the teeth and vice versa? “Basically, people with T2D have high blood sugar, and the sugar comes out in the saliva and that promotes bacterial growth in the mouth and plaque formation on the teeth and gum disease,” Samir Malkani, MD, clinical chief of endocrinology and diabetes at UMass Chan School of Medicine in Worcester, Massachusetts, told this news organization.

“Patients get gingivitis, they get periodontitis, and since the gums and the jaw are a single unit, if the gum disease gets very severe, then there’s loss of jawbone and the teeth could fall out,” he said. There’s also inflammation in the mouth, and “when you have generalized inflammation, it affects the whole body.”

Recent research in Europe suggested that “although the mechanisms behind these associations are partially unclear, poor oral health is probably sustaining systemic inflammation.” Common oral infections, periodontal disease, and cavities are associated with inflammatory metabolic profiles related to an increased risk for cardiometabolic diseases, and they predict future adverse changes in metabolic profiles, according to the authors.

Awareness, Accessibility, Collaboration

Despite the evidence, the connection between oral health and diabetes (any type) is not front of mind with clinicians or patients, Dr. Malkani said. He pointed to a systematic review that included 28 studies of close to 28,000 people in 14 countries. The review found that people with diabetes have “inadequate oral health knowledge, poor oral health attitudes, and fewer dental visits, [and] rarely receive oral health education and dental referrals from their care providers.”

Social determinants of health have a “huge impact” on whether people will develop T2D and its related complications, including poor oral health, according to the National Clinical Care Commission Report presented to the US Congress in 2022. The commission was charged with making recommendations for federal policies and programs that could more effectively prevent and control diabetes and its complications.

The commission “approached its charge through the lens of a socioecological and an expanded chronic care model,” the report authors wrote. “It was clear that diabetes in the US cannot simply be viewed as a medical or healthcare problem but also must be addressed as a societal problem that cuts across many sectors, including food, housing, commerce, transportation, and the environment.”

Diabetes also is associated with higher dental costs, another factor affecting an individual’s ability to obtain care.

A recent questionnaire-based study from Denmark found that people with T2D were more likely than those without diabetes to rate their oral health as poor, and that the risk for self-rated poor oral health increased with lower educational attainment. Highest educational attainment and disposable household income were indicators of a high socioeconomic position, and a lower likelihood of rating their oral health as poor, again pointing out inequities.

The authors concluded that “diabetes and dental care providers should engage in multidisciplinary collaboration across healthcare sectors to ensure coherent treatment and management of diabetes.”

But such collaborations are easier said than done. “One of the challenges is our fragmented health system, where oral health and medical care are separate,” Dr. Gabbay said.

For the most part, the two are separate, Dr. Malkani agreed. “When we’re dealing with most complications of diabetes, like involvement of the heart or eyes or kidneys, we can have interdisciplinary care — everyone is within the overall discipline of medicine, and if I refer to a colleague in ophthalmology or a cardiologist or a vascular surgeon, they can all be within the same network from an insurance point of view, as well.”

But for dental care, referrals are interprofessional, not interdisciplinary. “I have to make sure that the patient has a dentist because dentists are usually not part of medical networks, and if the patient doesn’t have dental insurance, then cost and access can be a challenge.”

A recent systematic review from Australia on interprofessional education and interprofessional collaborative care found that more than a third of medical professionals were “ignorant” of the relationship between oral health and T2D. Furthermore, only 30% reported ever referring their patients for an oral health assessment. And there was little, if any, interprofessional collaborative care between medical and dental professionals while managing patients with T2D.

Treat the Teeth

“We always talk to our T2D patients about the importance of getting an eye exam, a foot exam, and a kidney test,” Dr. Malkani said. “But we also need to make sure that they’re going to the dentist. Normally, people get their teeth cleaned twice a year. But if you have diabetes and poor oral health, you might need to get your teeth cleaned every three months, and insurance often will pay for that.”

Furthermore, in keeping with the bidirectional connection, treating periodontitis can help glycemic control. The authors of a 2022 update of a Cochrane review on treating periodontitis for glycemic control wrote that they “doubled the number of included studies and participants” from the 2015 update to 35 studies randomizing 3249 participants to periodontal treatment or control. This “led to a change in our conclusions about the primary outcome of glycemic control and in our level of certainty in this conclusion.”

“We now have moderate‐certainty evidence that periodontal treatment using subgingival instrumentation improves glycemic control in people with both periodontitis and diabetes by a clinically significant amount when compared to no treatment or usual care. Further trials evaluating periodontal treatment vs no treatment/usual care are unlikely to change the overall conclusion reached in this review.”

“Dentists also have a responsibility,” Dr. Malkani added. “If they see someone with severe gum disease or cavities, especially at a younger age, they need to tell that person to get their blood sugar checked and make sure they don’t have T2D.”

In fact, a recent review found that complications of T2D such as xerostomia and periodontal problems adversely affect well-being, and that “dentists can play an essential role in the awareness of diabetic patients about these problems and improve their quality of life.”

Key Stats

The US Centers for Disease Control and Prevention highlighted these facts about diabetes and oral health:

• Adults aged 20 years or older with diabetes are 40% more likely to have untreated cavities than similar adults without diabetes.
• About 60% of US adults with diabetes had a medical visit in the past year but no dental visit.
• Expanding healthcare coverage for periodontal treatment among people with diabetes could save each person about $6000 (2019 US dollars) over their lifetimes.
• Adults aged 50 years or older with diabetes lack functional dentition (have fewer than 20 teeth) 46% more often and have severe tooth loss (eight or fewer teeth) 56% more often than those without diabetes.
• Adults aged 50 years or older with diabetes are more likely to report that they have a hard time eating because of dental problems.
• Annual dental expenditures for an adult with diabetes are $77 (2017 US dollars) higher than for an adult without diabetes. This cost translates to $1.9 billion for the United States.

Physicians’ negative online reviews — fair or unfair — can scare away new patients. But practices don’t have to sit idly by and watch their revenue shrink.

Increasingly, they’re turning to apps and automated systems like DearDoc, Rater8, and LoyalHealth that ask satisfied patients to post reviews. The goal: To counteract the effect of negative reviews.

Not all of these systems are effective, according to physicians who’ve used them. Asking patients for reviews is still not fully accepted, either. Still, some apps have proved their worth, doctors say.

Karen Horton, MD, a plastic surgeon in San Francisco, California, has used an automated system for 3 years. Even though reviews from plastic surgery patients can be difficult to get, Dr. Horton said, she has accumulated 535, with an average rating of just under 5 stars on a 1- to 5-star scale.

Dr. Horton, who speaks on the topic, said unfair negative reviews are a problem that needs addressing.

“A bad review sometimes says more about the patient than the provider,” she said. “Patients can use online reviews to vent about some perceived misgiving.”

Automated requests can address this problem. “The best way to deal with negative reviews is to ask average patients to post reviews,” she said. “These patients are more likely to be positive, but they wouldn’t leave a review unless asked.”

How Automated Systems Work

A variety of vendors provide an automated review request process to practices and hospitals. DearDoc, Loyal Health, Rater8, and Simple Interact work with healthcare providers, while Birdeye, Reputation, and Thrive Management work with all businesses.

Typically, these vendors access the practice’s electronic health record to get patients’ contact information and the daily appointment schedule to know which patients to contact. Patients are contacted after their appointment and are given the opportunity to go directly to a review site and post.

Inviting patients digitally rather than in person may seem unwelcoming, but many people prefer it, said Fred Horton, president of AMGA consulting in Alexandria, Virginia, a subsidiary of the American Medical Group Association. (He is not related to Karen Horton.)

“People tend to be more honest and detailed when responding to an automated message than to a person,” Mr. Horton told this news organization. “And younger patients actually prefer digital communications.”

But Mike Coppola, vice president of AMGA consulting, isn’t keen about automation.

He said practices can instead assign staff to ask patients to post reviews or an office can use signage displaying a Quick Response (QR) code, a two-dimensional matrix often used in restaurants to access a menu. Patients who put their smartphone cameras over the code are taken directly to a review site.

Still, staff would still need to help each patient access the site to be as effective as automation, and a QR invitation may be ignored. Pat Pazmino, MD, a plastic surgeon in Miami, Florida, told this news organization his office displays QR codes for reviews, but “I’m not sure many patients really use them.”

Some automated systems can go too far. Dr. Pazmino said a vendor he hired several years ago contacted “every patient who had ever called my office. A lot of them were annoyed.”

He said the service generated only 20 or 30 reviews, and some were negative. He did not like that he was soliciting patients to make negative reviews. He canceled the service.

What Is the Cost and Return on Investment?

“Our system makes it as easy as possible for patients to place reviews,” said Ravi Kalidindi, CEO of Simple Interact, a Dallas-based vendor that markets to doctors.

Dr. Kalidindi said Simple Interact charges $95-$145 per provider per month, depending on how the tool is used. For each dollar in cost, the practice typically earns $10 in extra revenue, he said.

Orrin Franko, MD, a hand surgeon in San Leandro, California, started using an automated patient review tool several years ago. He said that after installation received 10 reviews per month, all 5-star. “Now we have well over 700 reviews that generate close to $500,000 a year for our three-doctor practice,” he said.

Karen Horton reports more modest results. One new review comes in every 3-4 weeks. “Getting online reviews is a challenge for plastic surgeons,” he said. “Most patients are very private about having work done.”

Dr. Kalidindi reported that very few patients respond to Simple Interact’s invitation, but the numbers add up. “Typically, 3 of 100 patients contacted will ultimately post a positive review,” he said. “That means that a practice that sees 600 patients a month could get 18 positive reviews a month.”

Practices can also build their own systems and avoid vendors’ monthly fees. Dr. Franko built his own system, while Dr. Horton contracted with SILVR Agency, a digital marketing company in Solana Beach, California, to build hers for a one-time cost of about $3000.

Why Should Doctors Care About Online Reviews?

Online review sites for doctors include HealthGrades, RateMDs, Realself, Vitals, WebMD, and Zocdoc. (Medscape Medical News is part of WebMD.) Potential patients also consult general review sites like Facebook, Google My Business, and Yelp.

Consumers tend to prefer doctors who have many reviews, but most doctors get very few. One survey found that the average doctor has only seven online reviews, while competitors may have hundreds.

Having too few reviews also means that just one or two negative reviews can produce a poor average rating. It’s virtually impossible to remove negative reviews, and they can have a big impact. A 1-star rating reduces consumers’ clicks by 11%, according to Brightlocal, a company that surveys consumers’ use of online ratings.

Online reviews also influence Google searches, even when consumers never access a review site, said Lee Rensch, product director at Loyal Health, an Atlanta, Georgia–based vendor that works exclusively with hospitals.

By far the most common way to find a doctor is to use Google to search for doctors “near me,” Mr. Rensch told this news organization. The Google search brings up a ranked list of doctors, based partly on each doctor’s ratings on review sites.

Mr. Rensch said 15%-20% of Google’s ranking involves the number of reviews the doctor has, the average star rating, and the newness of the reviews. Other factors include whether the provider has responded to reviews and the description of the practice, he said.

How many people use the internet to find doctors? One survey found that 72% of healthcare consumers do so. Furthermore, healthcare ranks second in the most common use of reviews, after service businesses and before restaurants, according to a Brightlocal survey.

Is it OK to Ask for Reviews?

Dr. Franko said asking for reviews is still not fully accepted. “There remains a spectrum of opinions and emotions regarding the appropriateness of ‘soliciting’ online reviews from patients,” he said.

Dr. Horton said review sites are also divided. “Google encourages businesses to remind customers to leave reviews, but Yelp discourages it,” she said. “It wants reviews to be organic and spontaneous.”

“I don’t think this is a problem,” said E. Scot Davis, a practice management consultant in Little Rock, Arkansas, and a board member of the Large Urology Group Practice Association. “Not enough people leave positive reviews, so it’s a way of balancing out the impact of a few people who make negative reviews.”

Indeed, other businesses routinely ask for online reviews and customers are often willing to oblige. Brightlocal reported that in 2022, 80% of consumers said they were prompted by local businesses to leave a review and 65% did so.

Some physicians may wonder whether it’s ethical to limit requests for reviews to patients who had positive experiences. Some vendors first ask patients about their experiences and then invite only those with positive ones to post.

Dr. Kalidindi said Simple Interact asks patients about their experiences as a way to help practices improve their services. He said patients’ experiences aren’t normally used to cull out dissatisfied patients unless the customer asks for it.

Loyal Health’s tool does not ask patients about their experiences, according to Loyal Health President Brian Gresh. He told this news organization he is opposed to culling negative reviewers and said it’s against Google policy.

Mr. Coppola at AMGA Consulting also opposes the practice. “It’s misleading not to ask people who had a bad experience,” he said. “Besides, if you only have glowing reviews, consumers would be suspicious.”

Meanwhile, everyone agrees that practices shouldn’t pay for online reviews. Dr. Horton said she believes this would be considered unprofessional conduct by the Medical Board of California.

Conclusion

Automated systems have helped practices attain more and better online reviews, boosting their revenue. Although some frown on the idea of prompting patients to leave reviews, others say it is necessary because some negative online reviews can be unfair and harm practices.

“I don’t think this is a problem,” said E. Scot Davis, a practice management consultant in Little Rock, Arkansas, and a board member of the Large Urology Group Practice Association. “Not enough people leave positive reviews, so it’s a way of balancing out the impact of a few people who make negative reviews.”

Indeed, other businesses routinely ask for online reviews and customers are often willing to oblige. Brightlocal reported that in 2022, 80% of consumers said they were prompted by local businesses to leave a review and 65% did so.

Some physicians may wonder whether it’s ethical to limit requests for reviews to patients who had positive experiences. Some vendors first ask patients about their experiences and then invite only those with positive ones to post.

Dr. Kalidindi said Simple Interact asks patients about their experiences as a way to help practices improve their services. He said patients’ experiences aren’t normally used to cull out dissatisfied patients unless the customer asks for it.

Loyal Health’s tool does not ask patients about their experiences, according to Loyal Health President Brian Gresh. He told this news organization he is opposed to culling negative reviewers and said it’s against Google policy.

Mr. Coppola at AMGA Consulting also opposes the practice. “It’s misleading not to ask people who had a bad experience,” he said. “Besides, if you only have glowing reviews, consumers would be suspicious.”

Meanwhile, everyone agrees that practices shouldn’t pay for online reviews. Dr. Horton said she believes this would be considered unprofessional conduct by the Medical Board of California.

Conclusion

Automated systems have helped practices attain more and better online reviews, boosting their revenue. Although some frown on the idea of prompting patients to leave reviews, others say it is necessary because some negative online reviews can be unfair and harm practices.

Physicians’ negative online reviews — fair or unfair — can scare away new patients. But practices don’t have to sit idly by and watch their revenue shrink.

Increasingly, they’re turning to apps and automated systems like DearDoc, Rater8, and LoyalHealth that ask satisfied patients to post reviews. The goal: To counteract the effect of negative reviews.

Not all of these systems are effective, according to physicians who’ve used them. Asking patients for reviews is still not fully accepted, either. Still, some apps have proved their worth, doctors say.

Karen Horton, MD, a plastic surgeon in San Francisco, California, has used an automated system for 3 years. Even though reviews from plastic surgery patients can be difficult to get, Dr. Horton said, she has accumulated 535, with an average rating of just under 5 stars on a 1- to 5-star scale.

Dr. Horton, who speaks on the topic, said unfair negative reviews are a problem that needs addressing.

“A bad review sometimes says more about the patient than the provider,” she said. “Patients can use online reviews to vent about some perceived misgiving.”

Automated requests can address this problem. “The best way to deal with negative reviews is to ask average patients to post reviews,” she said. “These patients are more likely to be positive, but they wouldn’t leave a review unless asked.”

How Automated Systems Work

A variety of vendors provide an automated review request process to practices and hospitals. DearDoc, Loyal Health, Rater8, and Simple Interact work with healthcare providers, while Birdeye, Reputation, and Thrive Management work with all businesses.

Typically, these vendors access the practice’s electronic health record to get patients’ contact information and the daily appointment schedule to know which patients to contact. Patients are contacted after their appointment and are given the opportunity to go directly to a review site and post.

Inviting patients digitally rather than in person may seem unwelcoming, but many people prefer it, said Fred Horton, president of AMGA consulting in Alexandria, Virginia, a subsidiary of the American Medical Group Association. (He is not related to Karen Horton.)

“People tend to be more honest and detailed when responding to an automated message than to a person,” Mr. Horton told this news organization. “And younger patients actually prefer digital communications.”

But Mike Coppola, vice president of AMGA consulting, isn’t keen about automation.

He said practices can instead assign staff to ask patients to post reviews or an office can use signage displaying a Quick Response (QR) code, a two-dimensional matrix often used in restaurants to access a menu. Patients who put their smartphone cameras over the code are taken directly to a review site.

Still, staff would still need to help each patient access the site to be as effective as automation, and a QR invitation may be ignored. Pat Pazmino, MD, a plastic surgeon in Miami, Florida, told this news organization his office displays QR codes for reviews, but “I’m not sure many patients really use them.”

Some automated systems can go too far. Dr. Pazmino said a vendor he hired several years ago contacted “every patient who had ever called my office. A lot of them were annoyed.”

He said the service generated only 20 or 30 reviews, and some were negative. He did not like that he was soliciting patients to make negative reviews. He canceled the service.

What Is the Cost and Return on Investment?

“Our system makes it as easy as possible for patients to place reviews,” said Ravi Kalidindi, CEO of Simple Interact, a Dallas-based vendor that markets to doctors.

Dr. Kalidindi said Simple Interact charges $95-$145 per provider per month, depending on how the tool is used. For each dollar in cost, the practice typically earns $10 in extra revenue, he said.

Orrin Franko, MD, a hand surgeon in San Leandro, California, started using an automated patient review tool several years ago. He said that after installation received 10 reviews per month, all 5-star. “Now we have well over 700 reviews that generate close to $500,000 a year for our three-doctor practice,” he said.

Karen Horton reports more modest results. One new review comes in every 3-4 weeks. “Getting online reviews is a challenge for plastic surgeons,” he said. “Most patients are very private about having work done.”

Dr. Kalidindi reported that very few patients respond to Simple Interact’s invitation, but the numbers add up. “Typically, 3 of 100 patients contacted will ultimately post a positive review,” he said. “That means that a practice that sees 600 patients a month could get 18 positive reviews a month.”

Practices can also build their own systems and avoid vendors’ monthly fees. Dr. Franko built his own system, while Dr. Horton contracted with SILVR Agency, a digital marketing company in Solana Beach, California, to build hers for a one-time cost of about $3000.

Why Should Doctors Care About Online Reviews?

Online review sites for doctors include HealthGrades, RateMDs, Realself, Vitals, WebMD, and Zocdoc. (Medscape Medical News is part of WebMD.) Potential patients also consult general review sites like Facebook, Google My Business, and Yelp.

Consumers tend to prefer doctors who have many reviews, but most doctors get very few. One survey found that the average doctor has only seven online reviews, while competitors may have hundreds.

Having too few reviews also means that just one or two negative reviews can produce a poor average rating. It’s virtually impossible to remove negative reviews, and they can have a big impact. A 1-star rating reduces consumers’ clicks by 11%, according to Brightlocal, a company that surveys consumers’ use of online ratings.

Online reviews also influence Google searches, even when consumers never access a review site, said Lee Rensch, product director at Loyal Health, an Atlanta, Georgia–based vendor that works exclusively with hospitals.

By far the most common way to find a doctor is to use Google to search for doctors “near me,” Mr. Rensch told this news organization. The Google search brings up a ranked list of doctors, based partly on each doctor’s ratings on review sites.

Mr. Rensch said 15%-20% of Google’s ranking involves the number of reviews the doctor has, the average star rating, and the newness of the reviews. Other factors include whether the provider has responded to reviews and the description of the practice, he said.

How many people use the internet to find doctors? One survey found that 72% of healthcare consumers do so. Furthermore, healthcare ranks second in the most common use of reviews, after service businesses and before restaurants, according to a Brightlocal survey.

Is it OK to Ask for Reviews?

Dr. Franko said asking for reviews is still not fully accepted. “There remains a spectrum of opinions and emotions regarding the appropriateness of ‘soliciting’ online reviews from patients,” he said.

Dr. Horton said review sites are also divided. “Google encourages businesses to remind customers to leave reviews, but Yelp discourages it,” she said. “It wants reviews to be organic and spontaneous.”

Long-term adherence to a plant-based diet was not tied to a greater risk of hip fracture and some plant-based regimens may actually reduce the risk, a large cohort study of postmenopausal women in the United States suggested.

Not all plant-centered regimens are healthful, however, and this study factored dietary quality into risk.

Writing in JAMA Network Open, the study authors compared the lowest to highest quintiles of Plant-Based Diet Index scores. They found the most recent intake of a healthy plant-based diet (hPDI) to be associated with a somewhat lower (21%) risk of fracture while the most recent intake of its unhealthy counterpart (uPDI) was linked to a somewhat higher (28%) risk.

“In addition, higher baseline scores in the uPDI were associated with higher risk of hip fracture,” wrote the researchers, led by Mercedes Sotos Prieto, PhD, a nutritional epidemiologist in the Department of Preventive Medicine and Public Health at the Autonomous University of Madrid.

Plant-based diets, characterized by higher consumption of plant foods and lower or no intake of animal foods, have raised concerns about their potential harm to bone health. In a recent meta-analysis, vegetarians, but particularly vegans with no consumption of any animal food, had a higher fracture risk and lower bone mineral density compared with omnivores.

Another study found that compared with meat eaters, fish eaters and vegetarians had a higher risk of hip fractures. These analyses, however, did not assess the quality of the plant-based diets.

“We hypothesized that the differences in the quality of the plant-based diets — whole grains, fruits, and vegetables vs refined carbohydrates or snacks, which are both plant-based but very different, would be important in the association for the risk of hip fracture,” Dr. Sotos Prieto said in an interview.
 

Study details

Her study drew on data from 70,285 postmenopausal White women who were in the US Nurses’ Health Study from 1984 through 2014; data were analyzed from Jan. 1 to July 31, 2023.

The mean age of the nurses was 54.92 years, and 2038 cases of hip fracture were reported during the study over as long as 30 years of follow-up.

Healthy plant foods included whole grains, fruits, vegetables, nuts, legumes, vegetable oils, and tea or coffee and received positive scores, whereas less healthy plant foods such as fruit juices, sweetened beverages, refined grains, potatoes, sweets, or desserts and animal foods received reversed scores. Dietary and lifestyle information was collected by self-reported questionnaires.

Individuals with higher hPDI scores were leaner, more physically active, less likely to be smokers, and more likely to use vitamin and calcium supplements. Not surprisingly, they also had higher intakes of dietary calcium and healthy plant foods and had lower intake of less healthy plant foods. “It’s plausible that reverse causation may account for the risk associations, as individuals with underlying health conditions that predisposed them to higher fracture risk may have changed their diet,” Dr. Sotos Prieto said. “In addition, baseline diet may reflect diet early on, which could be an important predictor of bone mineral density when there was more active bone turnover.”

Lack of information precluded adjustment for the use of anti-osteoporotic medication.

Neither the hPDI, with a hazard ratio (HR) for highest vs lowest quintile of 0.97 (95% confidence interval, 0.83-1.14) nor the uPDI, with an HR for highest vs lowest quintile of 1.02 (95% CI, 0.87-1.20) for diet adherence over the long term was associated with hip fracture risk.

For recent dietary intake in the highest vs lowest quintiles, however, the hPDI was associated with a 21% lower risk of hip fracture: HR, 0.79 (95% CI, 0.68-0.92; P = .02 for trend). In contrast, the uPDI was associated with a 28% higher risk: HR, 1.28 (95% CI, 1.09-1.51; P = .008 for trend).

Future studies in other populations are needed to confirm the results and enhance their generalizability, Dr. Sotos Prieto said. “Investigating the temporal dynamics of dietary patterns and their effects by examining how recent dietary changes may impact health outcomes over different timeframes is important.” In the meantime, people wishing to follow a plant-based diet should make sure it features high-quality foods.
