All mammalian life is dependent on a continuous supply of molecular oxygen. Molecular oxygen is carried to cells by noncovalent binding to the iron moiety in the hemoglobin of red blood cells. It is utilized within cells by noncovalent binding to the iron moiety in various microsomal and mitochondrial proteins, including myoglobin and cytochromes. Consequently, to efficiently utilize molecular oxygen all mammalian life is dependent on an adequate supply of iron. Surprisingly, in an era of high technology precision medicine, many pregnant women are iron deficient, anemic, and not receiving adequate iron supplementation.

Iron deficiency is prevalent in women and pregnant women

Women often become iron deficient because of pregnancy or heavy menstrual bleeding. During pregnancy, maternal iron is provided to supply the needs of the fetus and placenta. Additional iron is needed to expand maternal red blood cell volume and replace iron lost due to bleeding at delivery. In the National Health and Nutrition Examination Survey (NHANES) of 1988–1994, 11% of women aged 16 to 49 years were iron deficient. By contrast, less than 1% of men aged 16 to 49 years were iron deficient.¹

In a NHANES study from 1999–2006, risk factors for iron deficiency included multiparity, current pregnancy, and regular menstrual cycles. Use of hormonal contraception reduced the rate of iron deficiency.² Using the same data, the prevalences of iron deficiency during the first, second, and third trimesters of pregnancy were reported to be 7%, 14%, and 30%, respectively.³ In addition to pregnancy and menstrual bleeding there are many other medical problems that may contribute to iron deficiency, including Helicobacter pylori (H pylori) infection, gastritis, celiac disease, and bariatric surgery.

Iron deficiency anemia may be associated with adverse pregnancy outcomes

In a retrospective study of 75,660 singleton pregnancies, 7,977 women were diagnosed with iron deficiency anemia when they were admitted for delivery. Compared with pregnant women without iron deficiency, the presence of iron deficiency increased the risk of:

• blood transfusion (odds ratio [OR], 5.48; 95% confidence interval [CI], 4.57–6.58)
• preterm delivery (OR, 1.54; 95% CI, 1.36–1.76)
• cesarean delivery (OR, 1.30; 95% CI, 1.13–1.49)
• 5-minute Apgar score <7 (OR, 2.21; 95% CI, 1.84–2.64)
• intensive care unit (ICU) admission (OR, 1.28; 95% CI, 1.20–1.39).⁴

In a systematic review and meta-analysis of 26 studies, maternal anemia (mostly iron deficiency anemia) was associated with a higher risk of low birth weight (relative risk [RR], 1.31; 95% CI, 1.13–1.51), preterm birth (RR, 1.63; 95% CI, 1.33–2.01), perinatal mortality (RR, 1.51; 95% CI, 1.30–1.76), and neonatal mortality (RR, 2.72; 95% CI, 1.19–6.25).⁵

In a clinical trial, pregnant women were randomly assigned to receive folic acid alone; folic acid plus iron supplements; or 15 vitamins and minerals, including folic acid and iron. At delivery, women in the iron-folic acid and the 15 vitamin and minerals groups had higher hemoglobin concentrations than the folic acid monotherapy group. Among 4,697 live births, women in the iron-folic acid group had significantly fewer preterm births (<34 weeks’ gestation) than the folic acid group (RR, 0.50; 95% CI, 0.27–0.94; P = .031).⁶ Data from additional randomized trials are needed to further clarify the effect of iron supplementation on obstetric outcomes.

The diagnosis of iron deficiency is optimized by measuring serum ferritin

Serum ferritin measurement is an excellent test of iron deficiency. We recommend that all pregnant women have serum ferritin measured at the first prenatal visit and at the beginning of the third trimester to assess maternal iron stores. In pregnancy, the Centers for Disease Control and Prevention and the World Health Organization define anemia as a hemoglobin level of less than 11 g/dL or hematocrit less than 33% in the first and third trimesters. If a pregnant woman is not anemic, a serum ferritin level less than 15 ng/mL indicates iron deficiency.⁷ Some experts believe that in pregnant women who are not anemic, a serum ferritin level between 15 and 30 ng/mL may also indicate iron deficiency.⁸ If the pregnant woman is anemic and does not have another cause of the anemia, a serum ferritin level less than 40 ng/mL is indicative of iron deficiency.⁷

Ferritin is an acute phase reactant and levels may be falsely elevated due to chronic or acute inflammation, liver disease, renal failure, metabolic syndrome, or malignancy. Some women with iron deficiency due to bariatric surgery or malabsorption also have vitamin B12 and, less commonly, folate deficiency, which can contribute to the development of anemia (see “Diagnosis of anemia, iron deficiency, and iron deficiency anemia in pregnancy.”) Clinicians are often advised that a mean corpuscular volume demonstrating microcytosis is the “best test” to assess a patient for iron deficiency. However, reduced iron availability and low ferritin precede microcytosis. Hence microcytosis is a lagging measure and iron deficiency is diagnosed at an earlier stage by ferritin.

Dietary iron

Iron in food is present in heme (meat, poultry, fish) and non-heme forms (grains, plant food, supplements). Heme iron is better absorbed than non-heme iron. Foods rich in non-heme iron include spinach, lentils, prune juice, dried prunes, and fortified cereals. Absorption of non-heme iron can be increased by vitamin C or vitamin C–rich foods (broccoli, bell peppers, cantaloupe, grapefruit, oranges, strawberries, and tomatoes). Absorption of non-heme iron is reduced by consumption of dairy products, coffee, tea, and chocolate.

Oral iron treatment

Oral iron is an effective treatment for iron deficiency^9,10 and is inexpensive, safe, and widely available. The CDC recommends that all pregnant women take a 30 mg/day iron supplement, unless they have hemochromatosis.¹¹ For women with a low ferritin level and anemia, iron supplementation should be increased to 30 to 120 mg daily.¹¹ Not all prenatal vitamins contain iron; those that do typically contain 17 to 28 mg of elemental iron per dose.

Many pregnant women taking oral iron, especially at doses greater than 30 mg daily, have gastrointestinal side effects, which cause them to discontinue the iron therapy.¹² Taking iron supplementation on an intermittent basis may help to reduce gastrointestinal side effects and improve iron stores.¹³

In the past, a standard approach to the treatment of iron deficiency anemia was oral ferrous sulfate 325 mg (65 mg elemental iron) spaced in 3 doses each day for a total daily dose of 195 mg elemental iron. However, recent absorption studies concluded that maximal absorption of iron occurs with a dose in the range of 40 to 80 mg of elemental iron daily. Greater doses do not result in more iron absorption and are associated with more side effects.^14,15 (See “Start using alternate-day oral iron dosing, and stop using daily iron dosing.”)

Oral iron should not be taken in close approximation to the consumption of milk, cereals, tea, coffee, eggs, or calcium supplements. The absorption of oral iron is enhanced by the consumption of orange juice or 250 mg of vitamin C. Gastrointestinal side effects include nausea, flatulence, constipation, diarrhea, epigastric distress, and vomiting. If gastrointestinal side effects occur, interventions that might improve tolerability include: reduce the dose of iron or administer intermittently or use a low dose of oral iron, where dosing can be more easily titrated.

We re-check ferritin and hemoglobin levels 2 to 4 weeks after initiation of oral iron therapy and expect to see a hemoglobin rise of 1 g/dL if the therapy is effective.

Intravenous iron treatment

For women with iron deficiency anemia who cannot tolerate oral iron or in whom oral iron treatment has not resolved their anemia, intravenous (IV) iron treatment may be an optimal approach. Women in the third trimester of pregnancy with iron deficiency anemia have very little time to consume sufficient quantities of oral iron in food and supplements to restore their deficiency and reverse their anemia. Consequently, treatment with IV iron may be especially appropriate for women with iron deficiency anemia in the third trimester of pregnancy. Prior gastric surgery, including gastric bypass, results in reduced gastric acid production and causes severe impairment of intestinal absorption of iron. Patients with malabsorption syndromes, including celiac disease, also may have limited absorption of oral iron. These populations of pregnant women may particularly benefit from the use of IV iron. In pregnant women IV iron has fewer gastrointestinal side effects than oral iron.¹⁶

Many severely iron deficient patients need 1,000 mg of iron to resolve their deficit. In order to avoid giving multiple standard doses (200 mg per infusion, with 5 infusions over many days), some centers have explored the use of 1 large dose of IV iron (1,000 mg of low molecular weight iron dextran administered over 1 hour) (INFeD, Watson Pharma).^17–19 This is not a regimen that is specifically approved by the US Food and Drug Administration. An alternative regimen is to administer 750 mg of ferrous carboxymaltose (Injectafer, Luitpold Pharmaceuticals) over 15 minutes, which is an FDA-approved regimen.¹⁸ Many hematologists prefer to administer multiple smaller doses of iron. For example, in our practice, pregnant women are commonly treated with IV iron sucrose (300 mg) every 2 weeks for 3 doses. To increase access of pregnant women to IV iron treatment, obstetricians need to work with hematologists and infusion centers to create collaborative protocols to expeditiously treat women in the third trimester.

There is an epidemic of iron deficiency in pregnant women in the United States. In an era of high technology medicine, it is surprising that iron deficiency remains an unsolved obstetric problem in our country.

Over the past 3 decades, the prevalence of overweight and obesity has increased dramatically in the United States. A study published in 2016 showed the age-adjusted prevalence of obesity in 2013–2014 was 35% among men and 40.4% among women.¹ It comes as no surprise that increased reliance on inexpensive fast foods coupled with progressively more sedentary lifestyles have been implicated as causative factors.²

With the rise in obesity also has come an attendant rise in related chronic diseases, such as type 2 diabetes mellitus and cardiovascular disease. Women who are obese are also at risk for certain women’s health conditions, such as polycystic ovary syndrome, breast cancer, and endometrial cancer.

It is clear that curbing this public health crisis will require concerted efforts from individuals, clinicians, and policy makers, as well as changes in societal norms. OBG Management recently caught up with wellness expert Linda D. Bradley, MD, who shared in her latest book, “Us! Our Life. Our Health.” Our Legacy,” some practical strategies clinicians can use to help their patients manage their weight and prevent or reverse chronic diseases.

OBG Management: In your book you describe Jane, a patient who was severely overweight and who had low self-esteem. ³ You took 2 hours to convince Jane to talk about her clinical problems. That was clearly a heroic intervention on your part as the physician. What advice do you have for time-strapped clinicians who have patients who may need to face mental barriers in order to begin to address physical ailments?

Linda D. Bradley, MD: I think it is important for us not to lecture our patients. I could list all of the things that patients should or could do to prevent or even reverse disease states, in terms of eating right and exercising, but I think motivational interviewing is a more productive approach to elicit and evoke change (see “Principles and practice of motivational interviewing”). I used to preach to my patients. I would say, “You know, if you stay at this weight, you’re going to get diabetes, you’re going to increase your breast cancer risk, you’re going to have abnormal bleeding, you’re not going to be able to get pregnant,” and so on. It is easy to slip into that in the 7 minutes that you have with your patient, but to me, that is not the right way.

With motivational interviewing, our interactions with patients are shaped by:

• asking
• advising
• assisting
• arranging.

We begin by asking permission: “Do you mind if we talk about your weight?” or “Can we talk about your level of exercise?” Once the patient has granted permission, we ask open-ended questions and use reflective listening: “What I hear you saying is that you are concerned you will not be able to lose the weight,” or “It sounds like you don’t like to exercise, but you are worried about the health consequences of that.”

I find these skills useful for addressing anything from smoking to drinking to weight management to excessive shopping—any extreme behavior that is affecting a patient negatively. When a patient is not ready to talk about her clinical problems or make changes, I let her know my door is always open to her and that I have many resources available to help her when she is ready (TABLE).⁴ In those cases, I might say something like, “I have many patients who really don’t want to talk about this when I first ask them, but I just want you to know, Mrs. Jones, that I want you to succeed and I want you to be healthy. We have a team approach to taking care of all of you, and when you are ready, we are here to help.”

It is important to provide practical advice to patients—including how much to exercise, the importance of keeping a food journal, and determining a goal for slow, safe weight loss—and provide resources as necessary (such as for Weight Watchers, nutrition, and dieticians). Each day we have more than 30 opportunities to select foods to eat, drink, or purchase. Have a plan and advise your patients do the same. Recommend patients cook their own meals. Suggest weight loss apps. Counsel them to celebrate successes, find a buddy (for social support), practice positive self-talk (positive language), and plan for challenges (travel, parties, working late) and setbacks, which do not need to become a fall. Find an activity or exercise that the patient enjoys and tell them to seek professional help if needed.

Read about how to educate your patients on wellness.

OBG Management: You mention in your book that 70% to 80% of people now in hospitals are there because of diseases preventable through lifestyle choice. What are the women’s health conditions on that list?

Dr. Bradley: About 86% of the health care dollars spent in the United States are due to chronic diseases, and chronic diseases are the leading cause of death and disability in the country.⁵ The most common chronic diseases—cardiovascular disease, hypertension, type 2 diabetes, colon cancer, depression, dementia, cognitive problems, higher rates of fractures—all have been associated, at least in part, with unhealthy food choices and lack of exercise. That applies to breast cancer, too.

The good news is, we can prevent and even reverse disease. As Hippocrates said, let food be thy medicine and medicine be thy food. We have all seen success stories where consistent exercise and dietary changes definitely change the paradigm for what the disease state represents. A multiplicity of factors affect poor health—noncompliance, obesity, smoking—but when we begin to make consistent, healthy changes with diet and exercise, this creates a sort of domino effect.

OBG Management: You discuss chronic illness as preventable, manageable, and reversible. Where do you see the women’s health clinician’s role in the management of reversal?

Dr. Bradley: I think we need to get to the root cause of these clinical problems and provide the resources and support that patients need to reverse or even prevent these diseases. Clinicians need to become more aware—be an example and a role model. Our patients are watching us as much as we are watching them. Together, we can form good partnerships in order to promote better health.

OBG Management: Do you encourage your patients to write a wellness contract?

Dr. Bradley: I think when you are about to be a change agent for your body and become what I call the best version of yourself, you can have these great ideas, but you need to turn those ideas into actions and make them consistent. And we know that is difficult to do, so I do try to have patients write down specific goals, their plan for achieving them, and list the reasons why it is important for them to reach their goals. That gives them something tangible to look at when the going gets tough. It is also important to work into the contract ways to reward positive behaviors when goals are met, and to plan for challenges and setbacks and how to get back on track.

I also encourage patients to document their progress and learn how to make quick adjustments when necessary to get back on track. Another important element involves setting milestones—by what date are you going to reach this goal? Like any other contract, I have my patients date and sign their wellness contracts. I also encourage them to visualize what their new self is going to look like, how they will feel when they reach their goal, what they will wear, and what activities they will engage in.

OBG Management: Do you think that physicians have a role in educating their patients on food labels and dietary intake?

Dr. Bradley: I do, but the amount of nutrition education that most of us get in medical school is minimal to nonexistent and not practical. As physicians, we know that food is health, exercise is fitness, and that our patients need both of them. We also know that we did not get this information in school and that our education was more about treating disease than preventing disease. Many of us were not trained in robot surgery either, because it did not exist. So what did we do? We took classes, attended lectures, read books, and learned. We can do the same with wellness. There are many courses around the country. We have to begin to relearn and reteach ourselves about health, nutrition, and exercise and then pass that information on to our patients—be a resource and a guide. We should be able to write a prescription for health as quickly as we can write a prescription for insulin or a statin.

I also bring up portion distortion with my patients. The National Institutes of Health has resources on their website (https://www.nhlbi.nih.gov/health/educational /wecan/eat-right/portion-distortion.html) that include great visuals that show portion sizes 20 years ago and what they are now. For instance, 20 years ago a bagel was 3 inches and 140 calories; today’s bagel is 6 inches and 350 calories (plus whatever toppings are added). I tell that to my patients and then explain how much more exercise is needed to burn off just that 1 bagel.

OBG Management: Epigenetics: Do patients know about it?

Dr. Bradley: They may not know that term directly, but I think people understand that you have the potential to pass on poor lifestyle and/or health issues related to how things are when you are in utero and later in life. It gets back to letting people know to be healthy in pregnancy and even pre-pregnancy, and that includes one’s emotional state, physical state, and spiritual state. We are what we are in our mother’s womb. Getting the best start in life starts with a healthy mom, healthy dad, and a healthy environment.

Over the past 3 decades, the prevalence of overweight and obesity has increased dramatically in the United States. A study published in 2016 showed the age-adjusted prevalence of obesity in 2013–2014 was 35% among men and 40.4% among women.¹ It comes as no surprise that increased reliance on inexpensive fast foods coupled with progressively more sedentary lifestyles have been implicated as causative factors.²

With the rise in obesity also has come an attendant rise in related chronic diseases, such as type 2 diabetes mellitus and cardiovascular disease. Women who are obese are also at risk for certain women’s health conditions, such as polycystic ovary syndrome, breast cancer, and endometrial cancer.

It is clear that curbing this public health crisis will require concerted efforts from individuals, clinicians, and policy makers, as well as changes in societal norms. OBG Management recently caught up with wellness expert Linda D. Bradley, MD, who shared in her latest book, “Us! Our Life. Our Health.” Our Legacy,” some practical strategies clinicians can use to help their patients manage their weight and prevent or reverse chronic diseases.

OBG Management: In your book you describe Jane, a patient who was severely overweight and who had low self-esteem. ³ You took 2 hours to convince Jane to talk about her clinical problems. That was clearly a heroic intervention on your part as the physician. What advice do you have for time-strapped clinicians who have patients who may need to face mental barriers in order to begin to address physical ailments?

Linda D. Bradley, MD: I think it is important for us not to lecture our patients. I could list all of the things that patients should or could do to prevent or even reverse disease states, in terms of eating right and exercising, but I think motivational interviewing is a more productive approach to elicit and evoke change (see “Principles and practice of motivational interviewing”). I used to preach to my patients. I would say, “You know, if you stay at this weight, you’re going to get diabetes, you’re going to increase your breast cancer risk, you’re going to have abnormal bleeding, you’re not going to be able to get pregnant,” and so on. It is easy to slip into that in the 7 minutes that you have with your patient, but to me, that is not the right way.

With motivational interviewing, our interactions with patients are shaped by:

• asking
• advising
• assisting
• arranging.

We begin by asking permission: “Do you mind if we talk about your weight?” or “Can we talk about your level of exercise?” Once the patient has granted permission, we ask open-ended questions and use reflective listening: “What I hear you saying is that you are concerned you will not be able to lose the weight,” or “It sounds like you don’t like to exercise, but you are worried about the health consequences of that.”

I find these skills useful for addressing anything from smoking to drinking to weight management to excessive shopping—any extreme behavior that is affecting a patient negatively. When a patient is not ready to talk about her clinical problems or make changes, I let her know my door is always open to her and that I have many resources available to help her when she is ready (TABLE).⁴ In those cases, I might say something like, “I have many patients who really don’t want to talk about this when I first ask them, but I just want you to know, Mrs. Jones, that I want you to succeed and I want you to be healthy. We have a team approach to taking care of all of you, and when you are ready, we are here to help.”

EXPERT COMMENTARY

Health care services for women are fragmented due to multiple types of providers who offer a variety of care. Simon and Uddin’s recent research analysis indicates that the percentage of nonpregnant women who visit a general ObGyn, whether alone or in combination with an internist, family physician, or general practitioner, has declined.

Details of the study

The authors used data from the National Health Interview Survey of a representative sample of US women age 18 or older. They sought to identify whether the women saw or talked to a physician who either specialized in women’s health (presumably an ObGyn) or treated a variety of illnesses during the previous 12 months.

While the percentage of women who saw a general physician remained essentially the same (70%–74%), it declined for seeing an ObGyn from 45% to 41% between 2003 and 2007, and from 42% to 38% between 2011 and 2015. Furthermore, the percentage of women who saw both an ObGyn and a general physician declined from a peak of 35% in 2003 to 30% in 2015.

Study strengths and weaknesses

The data used in this study were from a nationally representative, cross-sectional, multistage sample, population health survey conducted by the Centers for Disease Control and Prevention. The study period was sufficient to draw conclusions.

From my perspective, the study had 2 major limitations: 1) only physicians, not mid-level providers, were included in the analysis, and 2) no breakdown of the women’s age groups was provided.

Many ObGyn offices employ nurse practitioners and midwives, and these providers’ roles are increasingly important for improving frontline access to care and different levels of care. Women aged 19 to 39 seek almost all their health care from ObGyns or family physicians, and significant sharing of care exists across these provider groups.¹ Women aged 45 to 64 are more likely to obtain care exclusively at the offices of family physicians or general internists than at those of ObGyns.² Most ObGyns are engaged to some degree with women aged 65 years or older, especially for preventive care, disease screening and early detection, and urogenital conditions.³

Drug overdose is the leading cause of death for Americans under age 50. And the number of men and women dying from drug overdose shows no abating, with a sharp 17% increase in 2016 over 2015.¹ The rate of fatal overdoses rose to nearly 20 people per 100,000 in 2016, according to the Centers for Disease Control and Prevention. The highest death rates are reported in West Virginia, New Hampshire, Kentucky, Ohio, and Rhode Island.²

Dr. Andrew Kolodny, director of opioid policy research at Brandeis University, told The New York Times that there are “roughly two groups of Americans that are getting addicted. We have an older group that is overdosing on pain medicine, and we have a younger group that is overdosing on black market opioids.”¹

Are ObGyns contributing to the over-prescription of opioid pain medications? Investigators from Florida Hospital, the University of Florida, and Orlando VA Medical Center are researching the question, and preliminary findings indicate that, yes, in fact “gynecologists are overprescribing postoperative prescription opioids in all levels of gynecologic surgery,” including after laparotomies and major and minor minimally invasive surgeries. Their work thus far, a prospective cohort study involving 113 patients enrolled to date, was presented November 15, 2017, in Washington, DC, as part of the 46th AAGL Global Congress on MIGS. They found that, on average, patients were prescribed 29.6 (SD, 9.3) opioid tablets, and they had 19.1 (SD, 12.6) tablets left over after surgery. Not surprisingly, patients undergoing major minimally invasive surgery and laparotomy were prescribed larger amounts of opioids than those undergoing minor minimally invasive surgery, but the amount of pain medication left over was similar regardless of surgery type.

The researchers also asked patients if they were told how to dispose of their leftover opioids; only 3 patients reported being told what to do if they had leftover medication.

Too many pills prescribed

In separate research presented at the meeting, investigators from Tufts Medical Center and Lahey Hospital and Medical Center in Boston, Massachusetts, sought to determine opioid prescription practices and patient opioid use after benign hysterectomy. Using retrospective online physician and telephone patient surveys, they found that 51 gynecologists prescribed a median of 30 tabs of oxycodone or hydromorphone after abdominal hysterectomy and a median of 20 tabs after laparoscopic or vaginal hysterectomy. Nearly 65% (36/56) of women used less than half of the opioids they were prescribed, and 16.1% (9/56) used zero tabs. Opioid use was not found to be significantly different for women undergoing abdominal versus minimally invasive hysterectomy.

Managing pain expectations

It takes only 3 days of opioid use for a patient to be at risk for continued use (1 to 3 years) of opioids, said Georgine Lamvu, MD, MPH, CPE, in the educational session “Perioperative Management of the Chronic Pain Patient” at the AAGL meeting. And long-term opioid use is associated with addiction, misuse, and mortality.³ It is therefore crucial to understand how to prescribe pain medications and how to educate women on expectations of pain relief.

Dr. Lamvu and fellow presenters described a 4-step process to pain management: 1) assess—including taking a history and physical exam and providing a risk assessment; 2) check—for other medications that a patient may be taking and possible interactions, as well make sure that the patient is not obtaining opioids or benzodiazepines from other providers; 3) discuss—what pain expectations you have for the patient following surgery; and 4) observe—for clinical improvement, overuse, and misuse, and go slow with dose increases and consult support pain management teams when needed.

Overall, they recommended that surgeons perform a risk assessment (determine the risks and benefits of available therapies); educate themselves and their patients on the risks and benefits; and document the risk assessment, the final recommendations to the patient, and the education provided to the patient.

“We need to do a lot better job at educating ourselves and our patients about pain medications and pain management strategies,” said Dr. Lamvu. The presenters provided these key points for patient and family education:

• Opioids are not first-line or routine therapy for chronic pain, and for acute pain they are used only for severe pain and in short-duration amounts.
• Analgesia will not make you pain free. It only helps to alleviate some pain, and most pain medications take 1 to 2 hours to take effect.
• A 30% improvement in pain and function can be expected for most therapies.
• Recovery from surgical or acute traumatic injury is not immediate; it is expected to take 2 to 4 weeks.
• Do not take extra medication doses beyond what is prescribed, and tell all of your providers what medications you are taking.
• Do not stop taking opioids suddenly, instead taper the dose slowly as instructed by your provider.
• Dispose of excess drugs appropriately—by taking unused pills back to your provider or crushing the pills, placing them in a small amount of liquid, and putting them in the trash.

“The reality is that the majority of patients are not using as many pills as we give them,” said Dr. Lamvu. “Adequate pain control does not supersede patient safety or the responsibility that we have as providers to our society.”

Drug overdose is the leading cause of death for Americans under age 50. And the number of men and women dying from drug overdose shows no abating, with a sharp 17% increase in 2016 over 2015.¹ The rate of fatal overdoses rose to nearly 20 people per 100,000 in 2016, according to the Centers for Disease Control and Prevention. The highest death rates are reported in West Virginia, New Hampshire, Kentucky, Ohio, and Rhode Island.²

Dr. Andrew Kolodny, director of opioid policy research at Brandeis University, told The New York Times that there are “roughly two groups of Americans that are getting addicted. We have an older group that is overdosing on pain medicine, and we have a younger group that is overdosing on black market opioids.”¹

Are ObGyns contributing to the over-prescription of opioid pain medications? Investigators from Florida Hospital, the University of Florida, and Orlando VA Medical Center are researching the question, and preliminary findings indicate that, yes, in fact “gynecologists are overprescribing postoperative prescription opioids in all levels of gynecologic surgery,” including after laparotomies and major and minor minimally invasive surgeries.

In a presentation of the Golden Hysteroscope Award Best Paper on Hysteroscopy at the 46th AAGL Global Congress on Minimally Invasive Surgery in National Harbor, Maryland, James Coad, MD, described a study that he and colleagues from West Virginia University School of Medicine in Morgantown, and Universidad Autónoma de Nuevo León in Monterrey, Mexico, conducted concerning the healing differences of cesarean incisions and the development of isthmoceles (cesarean scar defects).¹

Detecting isthmoceles

Isthmoceles are variably sized evaginations into the anterior lower uterine segment at a previous cesarean delivery incision due to suboptimal myometrium healing. This leads to thinning of the anterior uterine wall, which creates an indentation and fluid-filled pouch at the cesarean scar site.^1,2

Recent findings, say Coad and colleagues, associate isthmoceles with adverse reproductive and gynecologic conditions such as infertility, postmenstrual spotting, dysmenorrhea, and chronic pelvic pain. Patients who have undergone multiple cesarean deliveries tend to have larger isthmoceles with widths correlating to increased symptoms.¹

While the presence of inner nonunion healing can be hysteroscopically visualized, it is difficult to detect outer nonunion healing. The reported incidence of isthmoceles differs by imaging technique used: up to 70% are found with transvaginal ultrasound, and up to 84% are detected by sonohysterography.^3,4 This study found that 98% of isthomoceles can be detected by gross examination.¹

Study details

Researchers designed a prospective de-identified anatomic pathology study to evaluate the anatomy of uteri from 204 premenopausal women who underwent hysterectomy for benign disease due to abnormal uterine bleeding, fibroids, and/or adenomyosis. Uteri were midline sagittally sectioned and the area of cesarean section anatomy was documented, including the presence of inner and outer nonunion healing.¹

Of the 204 uteri, 134 (66%) had at least 1 identifiable cesarean scar (22% had 1 scar, 19% had 2 scars, and 25% had 3 or more scars). Of these, 2 uteri (1.5%) had intact incisional healing with minimal wall narrowing showing complete union healing. Isolated inner nonunion healing with the formation of prominent isthmoceles was found in 111 uteri (82.8%). Five uteri (3.7%) showed isolated outer nonunion healing without the formation of isthmoceles. Fourteen uteri (10.5%) had both inner and outer nonunion healing. Two uteri (1.5%) had complete transmural union healing with localized loss of anterior lower segment wall integrity. No isthmoceles were detected in women who had not undergone cesarean delivery.¹

Study results

When present, inner nonunion healing involved a mean (SD) 39% (23%; range, 5% – 90%) of the wall thickness and outer nonunion healing involved a mean (SD) 27% (17%; range, 10% – 60%). Due to nonunion healing, the resultant wall thicknesses at cesarean scar site were a mean (SD) 5.6 mm ( 2.60 mm; range, 0.0 mm – 14.2 mm). When compared with the adjacent uterine wall, the nonunion healing resulted in an approximate mean (SD) of 70% (16%) thinner wall. ¹

Conclusions and a warning

The authors concluded that, following cesarean delivery, there is a high incidence of architectural healing–related change, including significant inner and outer wall thinning. While inner nonunion healing can be hysteroscopically visualized, outer-wall healing cannot be visualized and may result in finding a thinner wall than expected during procedures in this region, including isthmocele repairs.¹
