Schizophrenia & Other Psychotic Disorders

Warning letters to primary care physicians (PCPs) regarding overprescription of quetiapine were helpful in reducing overprescribing of this agent, new research suggested.

Investigators analyzed data from an earlier trial that compared prescribing patterns in 5055 PCPs who receive a placebo letter or three warning letters informing them that their prescribing of quetiapine was high and under review by Medicare. Patients in question all had dementia and were either living in nursing homes or in the community.

The intervention reduced quetiapine use among all patients with dementia, with no detectable adverse effects on cognitive function, behavioral symptoms, depression, metabolic diagnoses, hospitalization, or death.

“This study found that overprescribing warning letters to PCPs safely reduced quetiapine prescribing to their patients with dementia,” wrote investigators led by Adam Sacarny, PhD, of the Department of Health Policy and Management, Mailman School of Public Health, Columbia University, New York. 

“This intervention and other[s] like it may be useful for future efforts to promote guideline-concordant care,” they added.

The study was published online in JAMA Network Open.
 

Off-Label Prescribing Common

The off-label use of antipsychotics in patients with dementia is fairly common, the investigators noted, affecting roughly one in seven nursing home residents and a similar number of community-dwelling older adults with dementia.

The agents are often prescribed to treat behavioral symptoms associated with dementia, including agitation and aggression. Although some evidence supports this use, antipsychotics in dementia patients can also cause an increased risk for weight gain, cognitive decline, falls and other injuries, cerebrovascular events, and mortality.

While some professional societies have called for “judicious use of antipsychotics in dementia care,” there is little evidence that reducing antipsychotic use in people with dementia might result in a benefit, investigators wrote.

The researchers analyzed data from a previous trial that focused on quetiapine, which is the most prescribed antipsychotic in the United States and is frequently used for patients with dementia.

In the original study, 2528 PCPs received a placebo letter and 2527 received three warning letters sent by the Centers for Medicare & Medicaid Services (CMS), which identified the highest-volume PCP prescribers of quetiapine.

The warning letters stated that the recipient’s quetiapine prescribing was high relative to their peers and was under review by Medicare. The placebo letter clarified an unrelated regulation. 

The current secondary analysis followed the providers and a cohort of their patients from their first receipt of the letters in 2015 through April 2017. The current evaluation analyzes patients’ outcomes through December 2018, utilizing Medicare fee-for-service claims, Minimum Data Set nursing home assessment, and Medicare enrollment data.
 

Low-Cost, Effective Intervention

While the original study focused on total quetiapine prescribing by study PCPs, the current analysis focused on patients’ total quetiapine use per 90-day period. Additional secondary outcomes included measures of cognitive function and behavioral symptoms, indicators of depression, metabolic diagnoses, indicators of use of hospital and healthcare services, and death.

PCPs in the study had a total of 84,881 patients with dementia living in nursing homes and 261,288 living in the community. At baseline, there were 92,874 patients (mean age, 82 years; 69% female).

The warning letters were associated with reduced quetiapine use among both nursing home patients and community-dwelling patients (adjusted difference, –0.7 days; P = .02 and adjusted difference, −1.5 days; P < .001, respectively).

Among nursing home patients, there were no statistically significant adverse changes in cognitive of behavioral health measures that coincided with reduction in quetiapine use.

Although a higher percentage of treatment vs control patients reported weight loss, the difference was not significant, and rates of metabolic diagnoses were similar in both groups. There were also no significant differences between the groups in emergency department use, inpatient hospital admission, or use of restraints.

Results were similar for patients living in the community.

Additionally, no adverse effects on more severe health endpoints, including rates of hospital use or entry to nursing facilities, were detected. Importantly, the risk for death was statistically significantly lower for patients whose PCPs had received warning letters vs control patients (P = .04).

The analysis “provides evidence that a low-cost letter intervention informed by behavioral science can reduce prescribing of quetiapine to patients with dementia in nursing home and community settings,” the authors wrote.

Researchers did not directly observe the administration of the medication but instead used prescription drug fills as a proxy. Moreover, they could not observe results for patients enrolled in Medicare Advantage, and claims-based and assessment-based outcomes might have been subject to measurement errors and under-ascertainment of diagnoses.

The authors received support from the National Institute on Aging. They reported no relevant financial relationships.

The US Drug Enforcement Agency (DEA) is moving forward with plans to move marijuana from a Schedule I to a Schedule III controlled substance under the Controlled Substance Act (CSA), the US Department of Justice officials announced this week. 

First reported by the Associated Press and since confirmed by this news organization through a US Department of Justice spokesperson, the news made international headlines. Despite the media splash, the final rule is still months away.

How did we get here? What happens next? What impact might rescheduling have on clinicians, patients, researchers, and the medical cannabis industry? 

Why Reschedule? Why Now? 

The DEA’s decision is based on a 2023 determination from the US Food and Drug Administration (FDA) that marijuana has a legitimate medical use and should be moved to Schedule III. 

DEA defines Schedule I drugs as those with no currently accepted medical use and a high potential for abuse. That class includes heroin, LSD, and ecstasy. Schedule III drugs have a moderate to low potential for physical and psychological dependence and have a currently accepted medical use. This class includes ketamine, acetaminophen with codeine, and buprenorphine. 

Even though the manufacturing, distribution, sale, and use of marijuana has long violated federal law, 38 states and Washington, DC, have legalized medical cannabis, and 24 states and DC have legalized its recreational use.

Congress has allowed states leeway for the distribution and use of medical marijuana, and current and previous presidential administrations have chosen not to aggressively pursue prosecution of state-allowed marijuana use, the Congressional Research Service (CRS) reports. 

Pressure to address the conflict between federal and state laws and an increasing interest in drug development of cannabis and cannabis-derived products probably contributed to the DEA’s decision, said Stephen Strakowski, MD, professor, and vice chair of psychiatry at Indiana University in Indianapolis, and professor and associate vice president at University of Texas in Austin.

“The trend toward legalization is everywhere and even though nationally the feds in this instance are lagging the states, the pressure to legalize has been intense for 50 years and it’s not surprising that the DEA is finally following that lead,” Dr. Strakowski told this news organization. 

How Does Rescheduling Work? What’s the Timeline?

The DEA will submit a formal rule proposing that marijuana be moved from Schedule I to Schedule III to the White House Office of Management and Budget. The timing of the submission is unclear. 

Once the proposed rule is posted to the Federal Register, there will be a public comment period, which usually lasts 30-60 days.

“This will likely generate a lot of public comment,” Robert Mikos, JD, LaRoche Family Chair in Law at Vanderbilt University Law School in Nashville, Tennessee, told this news organization. “Then the agency has to go back and wade through those comments and decide if they want to proceed with the rule as proposed or modify it.”

A final rule will probably be posted before the end of the current presidential term in January, Mr. Mikos said. While a lawsuit blocking its implementation is possible, there is a “low chance that a court would block this,” he added.

How Will Rescheduling Affect Medical Marijuana?

For medical marijuana, changing the drug to a Schedule III means that it can legally be prescribed but only in states that have legalized medical cannabis, Mr. Mikos said. 

“If you’re a patient in a state with a medical marijuana law and your physician gives you a prescription for medical marijuana and you possess it, you will no longer be guilty of a federal crime,” he said.

Rescheduling could also benefit patients who receive care through the Veterans Administration (VA), Mr. Mikos said. For several years, the VA has had a policy that blocked clinicians from prescribing medical marijuana because as a Schedule I drug, it was determined to have no accepted medical use. 

“It’s possible the VA may drop that policy once the drug gets rescheduled. If you’re in a medical marijuana state, if you’re a VA patient, and you don’t want to spend the extra money to go outside that system, this will have meaningful impact on their lives,” Mr. Mikos said.

But what about patients living in states that have not legalized medical cannabis? 

“You still wouldn’t be committing a federal crime, but you could be violating state law,” Mr. Mikos said. “That’s a much more salient consideration because if you look at who goes after individuals who possess small amounts of drugs, the state handles 99% of those cases.” 

The manufacture, distribution, and possession of recreational marijuana would remain illegal under federal law.

What Does It Mean for Medical Marijuana Dispensaries?

Though rescheduling makes it legal for clinicians to prescribe medical marijuana and for patients to use it, the actual sale of the drug will remain illegal under federal law because rescheduling only changes prescribing under the CSA, Mr. Mikos said.

“If you’re a dispensary and you sell it, even if it’s to somebody who’s got a prescription, you’re still probably violating the Food, Drug and Cosmetics Act. Rescheduling doesn’t change that,” he said. 

“Even assuming the DEA follows through with this and it doesn’t come undone at some future date, the industry is still going struggle to comply with the Controlled Substances Act post rescheduling because that statute is going to continue to impose a number of regulations on the industry,” Mr. Mikos added.

However, rescheduling would change the tax status of the estimated 12,000-15,000 state-licensed cannabis dispensaries in the United States, allowing access to certain tax deductions that are unavailable to sales involving Schedule I controlled substances, James Daily, JD, MS, with Center for Empirical Research in the Law at Washington University School of Law in St. Louis, told this news organization.

“Many cannabis businesses do in fact pay federal taxes, but the inability to take any federal tax credits or deductions means that their effective tax rate is much higher than it would otherwise be,” Mr. Daily said. 

Although new federal tax deductions would likely available to cannabis businesses if marijuana were rescheduled to Schedule III, “their business would still be in violation of federal law,” he said. 

“This creates a further tension between state and federal law, which could be resolved by further legalization or it could be resolved by extending the prohibition on tax deductions to include cannabis and not just Schedule I and II drugs,” he added.

Will Rescheduling Make It Easier to Conduct Cannabis-Related Research? 

Research on medical cannabis has been stymied by FDA and DEA regulations regarding the study of Schedule I controlled substances. Although rescheduling could lift that barrier, other challenges would remain.

“Schedule III drugs can be more easily researched, but it’s unclear if, for example, a clinical trial could lawfully obtain the cannabis from a dispensary or if they would still have to go through the one legal federal supplier of cannabis,” Daily said. 

The FDA reports having received more than 800 investigational new drug applications for and pre-investigational new drug applications related to cannabis and cannabis-derived products since the 1970s, the agency reports. To date, the FDA has not approved any marketing drug applications for cannabis for the treatment of any disease or condition. 

In January 2023, the agency published updated guidelines for researchers and sponsors interested in developing drugs containing cannabis or cannabis-derived compounds. 

It’s unclear whether those guidelines would be updated if the rescheduling moves forward. 

Does Rescheduling Marijuana Pose Any Risk? 

In its report to the DEA that marijuana be rescheduled, the FDA was careful to note that the agency’s recommendation is “not meant to imply that safety and effectiveness have been established for marijuana that would support FDA approval of a marijuana drug product for a particular indication.”

That’s a notation that clinicians and patients should take to heart, Dr. Strakowski said. 

“It’s important to remind people that Schedule III drugs, by definition, have addiction and other side effect risks,” he said. “The celebrity marketing that sits behind a lot of this is incompletely informed. It’s portrayed as fun and harmless in almost every movie and conversation you see, and we know that’s not true.”

Previous studies have linked cannabis to increased risk for mania, anxiety disorders, and schizophrenia. 

“It is increasingly clear that marijuana use is linked to poor outcomes in people who struggle with mental illness,” Dr. Strakowski said. “We have no evidence that it can help you but there is evidence that it can harm you.”

Dr. Strakowski likens cannabis use to alcohol, which is a known depressant that is associated with worse outcomes in people with mental illness. 

“I think with cannabis, we don’t know enough about it yet, but we do know that it does have some anxiety risks,” he said. “The risks in people with mental illness are simply different than in people who don’t have mental illness.”

Dr. Strakowski, Mr. Mikos, and Mr. Daily report no relevant disclosures.

Rescheduling could also benefit patients who receive care through the Veterans Administration (VA), Mr. Mikos said. For several years, the VA has had a policy that blocked clinicians from prescribing medical marijuana because as a Schedule I drug, it was determined to have no accepted medical use. 

“It’s possible the VA may drop that policy once the drug gets rescheduled. If you’re in a medical marijuana state, if you’re a VA patient, and you don’t want to spend the extra money to go outside that system, this will have meaningful impact on their lives,” Mr. Mikos said.

But what about patients living in states that have not legalized medical cannabis? 

“You still wouldn’t be committing a federal crime, but you could be violating state law,” Mr. Mikos said. “That’s a much more salient consideration because if you look at who goes after individuals who possess small amounts of drugs, the state handles 99% of those cases.” 

The manufacture, distribution, and possession of recreational marijuana would remain illegal under federal law.

What Does It Mean for Medical Marijuana Dispensaries?

Though rescheduling makes it legal for clinicians to prescribe medical marijuana and for patients to use it, the actual sale of the drug will remain illegal under federal law because rescheduling only changes prescribing under the CSA, Mr. Mikos said.

“If you’re a dispensary and you sell it, even if it’s to somebody who’s got a prescription, you’re still probably violating the Food, Drug and Cosmetics Act. Rescheduling doesn’t change that,” he said. 

“Even assuming the DEA follows through with this and it doesn’t come undone at some future date, the industry is still going struggle to comply with the Controlled Substances Act post rescheduling because that statute is going to continue to impose a number of regulations on the industry,” Mr. Mikos added.

However, rescheduling would change the tax status of the estimated 12,000-15,000 state-licensed cannabis dispensaries in the United States, allowing access to certain tax deductions that are unavailable to sales involving Schedule I controlled substances, James Daily, JD, MS, with Center for Empirical Research in the Law at Washington University School of Law in St. Louis, told this news organization.

“Many cannabis businesses do in fact pay federal taxes, but the inability to take any federal tax credits or deductions means that their effective tax rate is much higher than it would otherwise be,” Mr. Daily said. 

Although new federal tax deductions would likely available to cannabis businesses if marijuana were rescheduled to Schedule III, “their business would still be in violation of federal law,” he said. 

“This creates a further tension between state and federal law, which could be resolved by further legalization or it could be resolved by extending the prohibition on tax deductions to include cannabis and not just Schedule I and II drugs,” he added.

Will Rescheduling Make It Easier to Conduct Cannabis-Related Research? 

Research on medical cannabis has been stymied by FDA and DEA regulations regarding the study of Schedule I controlled substances. Although rescheduling could lift that barrier, other challenges would remain.

“Schedule III drugs can be more easily researched, but it’s unclear if, for example, a clinical trial could lawfully obtain the cannabis from a dispensary or if they would still have to go through the one legal federal supplier of cannabis,” Daily said. 

The FDA reports having received more than 800 investigational new drug applications for and pre-investigational new drug applications related to cannabis and cannabis-derived products since the 1970s, the agency reports. To date, the FDA has not approved any marketing drug applications for cannabis for the treatment of any disease or condition. 

In January 2023, the agency published updated guidelines for researchers and sponsors interested in developing drugs containing cannabis or cannabis-derived compounds. 

It’s unclear whether those guidelines would be updated if the rescheduling moves forward. 

Does Rescheduling Marijuana Pose Any Risk? 

In its report to the DEA that marijuana be rescheduled, the FDA was careful to note that the agency’s recommendation is “not meant to imply that safety and effectiveness have been established for marijuana that would support FDA approval of a marijuana drug product for a particular indication.”

That’s a notation that clinicians and patients should take to heart, Dr. Strakowski said. 

“It’s important to remind people that Schedule III drugs, by definition, have addiction and other side effect risks,” he said. “The celebrity marketing that sits behind a lot of this is incompletely informed. It’s portrayed as fun and harmless in almost every movie and conversation you see, and we know that’s not true.”

Previous studies have linked cannabis to increased risk for mania, anxiety disorders, and schizophrenia. 

“It is increasingly clear that marijuana use is linked to poor outcomes in people who struggle with mental illness,” Dr. Strakowski said. “We have no evidence that it can help you but there is evidence that it can harm you.”

Dr. Strakowski likens cannabis use to alcohol, which is a known depressant that is associated with worse outcomes in people with mental illness. 

“I think with cannabis, we don’t know enough about it yet, but we do know that it does have some anxiety risks,” he said. “The risks in people with mental illness are simply different than in people who don’t have mental illness.”

Dr. Strakowski, Mr. Mikos, and Mr. Daily report no relevant disclosures.

Most people experiencing homelessness have mental health disorders, according to a systematic review and meta-analysis.

In an examination of studies that included nearly 50,000 participants, the current prevalence of mental health disorders among people experiencing homelessness was 67% and the lifetime prevalence was 77%.

“The relationship is likely bidirectional, where experiencing homelessness may exacerbate mental health symptoms or where having a mental health disorder may increase an individual’s risk for experiencing homelessness,” lead author Rebecca Barry, PhD, a postdoctoral fellow at the University of Calgary in Calgary, Alberta, Canada, told this news organization. 

“There are also likely stressors that increase both risk for homelessness and risk for developing mental health disorders. This study examines prevalence but does not examine causal relationships,” she said.

The findings were published in JAMA Psychiatry.
 

A Growing Problem 

To determine the current and lifetime prevalence of mental health disorders among the homeless population, the researchers analyzed 85 studies that examined this question in participants aged ≥ 18 years. The review included 48,414 participants, including 11,154 (23%) women and 37,260 (77%) men.

The lifetime prevalence of mental health disorders was significantly higher in men experiencing homelessness (86%) than in women (69%). The most common mental health disorder was substance use disorder (44%), followed by antisocial personality disorder (26%), major depression (19%), bipolar disorder (8%), and schizophrenia (7%).

The prevalence of current and lifetime mental health disorders among the homeless population was higher than that that observed in the general population (13%-15% and 12%-47%, respectively).

The results resembled those of a previous review that estimated that 76% of people experiencing homelessness living in high-income countries have mental health disorders.

“Even though our results are not surprising, they still are drawing attention to this issue because it is a big problem in Canada, the United States, Europe, and other places,” senior author Dallas Seitz, MD, PhD, professor of psychiatry at the University of Calgary’s Cumming School of Medicine, told this news organization. “The problem is concerning, and it’s not getting better. Addiction and mental health problems are becoming more common among people who are homeless.” 

The bottom line is that people need affordable housing and mental health support, said Dr. Seitz. “It’s a housing problem and a health problem, and we need adequate resources to find better ways for those two systems to collaborate. There are public safety concerns, and we have to try and bring services to people experiencing homelessness. You have to come and meet people where they’re at. You have to try and establish a trusting relationship so that we can get people on the path to recovery.”
 

‘It’s Really About Income’ 

Commenting on the findings for this news organization, Stephen Hwang, MD, professor of medicine at the University of Toronto, Toronto, Ontario, Canada, said, “There have been previous studies of this type, but it is good to have an updated one.” Dr. Hwang, who is also chair in Homelessness, Housing, and Health at St. Michael’s Hospital, did not participate in the research. 

The findings must be understood in the proper context, he added. For one thing, grouping together all mental health disorders and giving a single prevalence figure can be misleading. “They are including in that category a diverse group of conditions. Substance use disorder, personality disorder, schizophrenia, and depression are all lumped together. The 67% prevalence seems very high, but it is a combination of many different conditions. I just don’t want people to look at that number and think that this means that everyone is a substance user or everyone has schizophrenia,” said Dr. Hwang. 

Also, some readers might interpret the findings to mean that mental problems are the reason people are homeless, he added. “That would be an incorrect interpretation because what this study is showing is that people with mental health disorders have a higher risk for becoming homeless. It doesn’t mean that it caused their homelessness. What really causes homelessness is a lack of affordable housing,” said Dr. Hwang.

“In a city or community where housing is very expensive, there’s not enough for everyone to be housed, there is a lot of competition for housing, and there’s not enough affordable housing for a number of reasons, we know that people with mental health conditions and substance use disorders will be among the first to lose their housing,” he said.

“It’s really about income. There are many reasons why a person cannot afford housing. So, not being able to earn enough money to afford it because you have a mental health disorder or substance use disorder is a common underlying reason for homelessness.”

Dr. Hwang also pointed out that people with mental illness who can access support, either through family members or through mental health care, and who also have the income to afford such services do not become homeless.

“Schizophrenia is seen in every population of the world at a rate of 1%. But you travel to certain cities and you see people who appear to have schizophrenia wandering the streets, and you go to other cities in the world and you don’t see anyone who looks like they’re homeless and have schizophrenia,” he said. 

“It’s not because there are fewer people with schizophrenia in those cities or countries; it’s because people with schizophrenia are treated differently. The rate of homelessness is determined not by how many people have that condition [eg, schizophrenia] but by how we treat those people and how we set up our society to either support or not support people who have disabilities.”

The study was funded by the Precision Care With Information, Science and Experience – Mental Health grant funded by the Calgary Health Foundation. Dr. Barry is supported by the Harley Hotchkiss Samuel Weiss Postdoctoral Fellowship awarded by the Hotchkiss Brain Institute at the University of Calgary. Dr. Barry reported having no relevant financial relationships. Dr. Seitz reported grants from Calgary Health Foundation during the conduct of the study as well as grants from University Health Foundation, the Canadian Institutes of Health Research, the Public Health Agency of Canada, the Alzheimer’s Association, and the Hotchkiss Brain Institute. He received honoraria for guideline development from the Canadian Coalition for Seniors Mental Health outside the submitted work. Dr. Hwang reported no relevant financial relationships.

BUDAPEST, HUNGARY — Self-perceived loneliness during childhood is linked to a more than twofold increased risk for subsequent first-episode psychosis (FEP) — new findings that may point to a novel marker for the disorder.

The association between loneliness and FEP “appears to extend beyond the effects of objective social isolation,” said study presenter Covadonga M. Díaz-Caneja, MD, PhD, Institute of Psychiatry and Mental Health, Hospital General Universitario Gregorio Marañón, Madrid, and “is particularly pronounced in females.”

“These findings suggest the potential of childhood loneliness as an early risk marker for psychosis that could help guide targeted interventions,” she added.

The results were presented at the European Psychiatric Association 2024 Congress.
 

Isolation a Major Risk Factor

There are two components to isolation, both of which are “major risk factors” for morbidity, mortality, and the onset of mental disorders, said Dr. Díaz-Caneja.

The first is “objective social isolation,” which consists of a demonstrable lack of social connections, including social interactions, contacts, and relationships, while the other is a perceived sense of isolation, or “loneliness,” defined as a “subjective feeling of distress associated with a lack of meaningful relationships,” regardless of the amount of actual social contact an individual experiences.

Childhood loneliness occurs before age 12 and is becoming increasingly prevalent, said Dr. Díaz-Caneja. A recent survey shows that approximately one third of children report they often feel lonely.

Genetic and observational research has shown there is a bidirectional relationship between loneliness and psychosis and that patients with schizophrenia are more likely to report loneliness than is the general population.

Dr. Díaz-Caneja noted that there is no previous research that has assessed the potential association between childhood loneliness and subsequent psychosis.

To investigate, the researchers conducted an observational, case-control study in seven university hospitals in Madrid. It included individuals aged 7-40 years, including FEP patients with a psychosis duration of less than 2 years, and healthy controls from the same geographic areas.

They assessed childhood objective social isolation using the Premorbid Adjustment Scale and examined childhood loneliness with the single item: “Have you ever felt lonely for more than 6 months before the age of 12?”

A range of measures and questionnaires were also administered to assess participants’ symptom scores, alongside the Global Assessment of Functioning (GAF).
 

Alone vs Lonely

Two hundred eighty-five patients with FEP participated in the study. They had a mean age of 24.5 years, and 32.6% were female. The study also included 261 healthy controls (average age, 25.9 years; 48.7% female).

After the researchers adjusted for age, gender, ethnicity, and socioeconomic status, loneliness during childhood was associated with a significantly increased risk for FEP (odds ratio [OR], 2.17; 95% CI, 1.40-3.51), which increased (OR, 2.70; 95% CI, 1.58-4.62) after further adjustment for objective social isolation.

Further analysis revealed that in those who did not have objective social isolation in childhood, loneliness was associated with a significantly increased risk for FEP (OR, 2.68; 95% CI, 1.56-4.60).

However, the relationship between loneliness and FEP was not significant in participants who were objectively socially isolated during childhood (OR, 0.33; 95% CI, 0.08-1.45).

Compared with males, females reporting loneliness had a markedly increased risk for FEP (OR, 4.74; 95% CI, 2.23-10.05 vs OR, 1.17; 95% CI, 0.63-2.19).

However, females had a reduced risk of receiving a diagnosis of schizophrenia spectrum disorder (OR, 0.155; 95% CI, 0.048-0.506), indicating that loneliness influenced the type of diagnosis, she noted.

There was a significant positive relationship between loneliness in childhood and symptom scores in men, and a negative association with GAF scores in men.

Dr. Díaz-Caneja noted that the study is preliminary and a “work in progress.” The investigators plan to increase the sample size and will conduct more complex analyses, she said.

“We also of course have to bear in mind that it is a cross-sectional study and that there may be some kind of recall biases [because] we are asking patients now about what happened in the past.”

She noted that it’s unclear whether the results can be extrapolated to individuals who are currently experiencing loneliness because “the determinants of loneliness 10 years ago or 15 years ago may be different.”
 

How, When to Intervene

Session chair Judit Lazáry, MD, PhD, Department of Clinical and Theoretical Mental Health, Kútvölgyi Clinical Center, Semmelweis University, Budapest, Hungary, told this news organization that the association between loneliness and FEP was “not surprising.”

She explained there are a lot of data indicating that premorbid symptoms in childhood are “predictive signs for the later onset of psychosis,” and loneliness may be “a part of that.”

Individuals experiencing loneliness are more anxious and have difficulties in cultivating and maintaining relationships. In addition, they tend to socially isolate, she said.

The key question, said Dr. Lazáry, is: “How can we intervene to prevent the onset of psychosis? What is the point at which we can support the young person?”

This is challenging, she added, because while “you can detect that a kid is always alone, you cannot detect the feeling of loneliness,” and children can’t always easily express themselves.

Another potential confounder is that in adults with current psychosis, the self-perception that they were lonely during childhood may be a consequence of the disorder.

In addition, she said, individuals with psychosis often experience cognitive impairment, which could affect memory reliability.

Nevertheless, said Dr. Lazáry, the study’s findings suggest that a young person reporting loneliness in childhood may be “another symptom that we have to investigate.”

No funding was declared.

Dr. Díaz-Caneja declared a relationship with Angelini, Janssen, and Viatris and grant support from Instituto de Salud Carlos III, the Spanish Ministry of Science and Innovation, and the European Commission.

Individuals experiencing loneliness are more anxious and have difficulties in cultivating and maintaining relationships. In addition, they tend to socially isolate, she said.

The key question, said Dr. Lazáry, is: “How can we intervene to prevent the onset of psychosis? What is the point at which we can support the young person?”

This is challenging, she added, because while “you can detect that a kid is always alone, you cannot detect the feeling of loneliness,” and children can’t always easily express themselves.

Another potential confounder is that in adults with current psychosis, the self-perception that they were lonely during childhood may be a consequence of the disorder.

In addition, she said, individuals with psychosis often experience cognitive impairment, which could affect memory reliability.

Nevertheless, said Dr. Lazáry, the study’s findings suggest that a young person reporting loneliness in childhood may be “another symptom that we have to investigate.”

BUDAPEST, HUNGARY — Self-perceived loneliness during childhood is linked to a more than twofold increased risk for subsequent first-episode psychosis (FEP) — new findings that may point to a novel marker for the disorder.

The association between loneliness and FEP “appears to extend beyond the effects of objective social isolation,” said study presenter Covadonga M. Díaz-Caneja, MD, PhD, Institute of Psychiatry and Mental Health, Hospital General Universitario Gregorio Marañón, Madrid, and “is particularly pronounced in females.”

“These findings suggest the potential of childhood loneliness as an early risk marker for psychosis that could help guide targeted interventions,” she added.

The results were presented at the European Psychiatric Association 2024 Congress.
 

Isolation a Major Risk Factor

There are two components to isolation, both of which are “major risk factors” for morbidity, mortality, and the onset of mental disorders, said Dr. Díaz-Caneja.

The first is “objective social isolation,” which consists of a demonstrable lack of social connections, including social interactions, contacts, and relationships, while the other is a perceived sense of isolation, or “loneliness,” defined as a “subjective feeling of distress associated with a lack of meaningful relationships,” regardless of the amount of actual social contact an individual experiences.

Childhood loneliness occurs before age 12 and is becoming increasingly prevalent, said Dr. Díaz-Caneja. A recent survey shows that approximately one third of children report they often feel lonely.

Genetic and observational research has shown there is a bidirectional relationship between loneliness and psychosis and that patients with schizophrenia are more likely to report loneliness than is the general population.

Dr. Díaz-Caneja noted that there is no previous research that has assessed the potential association between childhood loneliness and subsequent psychosis.

To investigate, the researchers conducted an observational, case-control study in seven university hospitals in Madrid. It included individuals aged 7-40 years, including FEP patients with a psychosis duration of less than 2 years, and healthy controls from the same geographic areas.

They assessed childhood objective social isolation using the Premorbid Adjustment Scale and examined childhood loneliness with the single item: “Have you ever felt lonely for more than 6 months before the age of 12?”

A range of measures and questionnaires were also administered to assess participants’ symptom scores, alongside the Global Assessment of Functioning (GAF).
 

Alone vs Lonely

Two hundred eighty-five patients with FEP participated in the study. They had a mean age of 24.5 years, and 32.6% were female. The study also included 261 healthy controls (average age, 25.9 years; 48.7% female).

After the researchers adjusted for age, gender, ethnicity, and socioeconomic status, loneliness during childhood was associated with a significantly increased risk for FEP (odds ratio [OR], 2.17; 95% CI, 1.40-3.51), which increased (OR, 2.70; 95% CI, 1.58-4.62) after further adjustment for objective social isolation.

Further analysis revealed that in those who did not have objective social isolation in childhood, loneliness was associated with a significantly increased risk for FEP (OR, 2.68; 95% CI, 1.56-4.60).

However, the relationship between loneliness and FEP was not significant in participants who were objectively socially isolated during childhood (OR, 0.33; 95% CI, 0.08-1.45).

Compared with males, females reporting loneliness had a markedly increased risk for FEP (OR, 4.74; 95% CI, 2.23-10.05 vs OR, 1.17; 95% CI, 0.63-2.19).

However, females had a reduced risk of receiving a diagnosis of schizophrenia spectrum disorder (OR, 0.155; 95% CI, 0.048-0.506), indicating that loneliness influenced the type of diagnosis, she noted.

There was a significant positive relationship between loneliness in childhood and symptom scores in men, and a negative association with GAF scores in men.

Dr. Díaz-Caneja noted that the study is preliminary and a “work in progress.” The investigators plan to increase the sample size and will conduct more complex analyses, she said.

“We also of course have to bear in mind that it is a cross-sectional study and that there may be some kind of recall biases [because] we are asking patients now about what happened in the past.”

She noted that it’s unclear whether the results can be extrapolated to individuals who are currently experiencing loneliness because “the determinants of loneliness 10 years ago or 15 years ago may be different.”
 

How, When to Intervene

The ketogenic diet shows promise in reducing the symptoms of bipolar disorder and schizophrenia and reversing metabolic syndrome, results of a new pilot study show. 

Participants who adhered to the high-fat, low-carb diet experienced a 30% reduction in psychiatric symptoms and an average 10% reduction in weight. 

“We’re seeing huge changes,” first author Shebani Sethi, MD, of Stanford University in Stanford, California said in a press release. “Even if you’re on antipsychotic drugs, we can still reverse the obesity, the metabolic syndrome, and the insulin resistance. I think that’s very encouraging for patients.”

The findings were published online in Psychiatric Research. 
 

Neuroprotective Effect? 

Recent research supports the hypothesis that psychiatric illness may stem, at least in part, from deficits in brain metabolism and that a keto diet may be neuroprotective by reducing inflammation and oxidative stress. 

The pilot study included 21 participants with schizophrenia (n = 5) or bipolar disorder (n = 16) who were aged 18-75 years. All were currently taking psychotropic medications. Participants were overweight (body mass index [BMI] ≥ 25) and had gained more than 5% of their body mass while taking psychotropic medication, or they had at least one metabolic abnormality, such as insulin resistance or dyslipidemia. 

At baseline, participants received a physical and psychiatric evaluation and 1 hour of instruction on how to implement the keto diet, which included 10% carbohydrate, 30% protein, and 60% fat. 

Investigators monitored blood ketone levels at least once a week and defined participants as keto-adherent if their levels were 0.5-5 mM for 80%-100% of the times they were measured.

Health coaches checked in with participants for about 5-10 minutes each week to answer diet-related questions.

Psychiatric assessments, which included mood rating and global functioning scales, were completed at baseline, 2 months, and at the end of the 4-month study. 

The research team tracked participants’ adherence to the diet by weekly measurement of blood ketone levels. 

By the end of the trial, 14 patients had been fully adherent with the diet, six had been semi-adherent, and only one had been nonadherent. Higher ketone levels, suggesting greater adherence, correlated with better metabolic health.

As measured by the Clinical Global Impression-Schizophrenia and Clinical Global Impression for Bipolar Disorder–Overall Severity, participants experienced a 31% reduction in symptom severity (P < .001). Overall, 43% (P < .02) of participants achieved recovery as defined by the Clinical Mood Monitoring Form criteria: 50% of the adherent group and 33% of those who were semi-adherent.
 

Metabolic Benefits

Initially, 29% of participants had metabolic syndrome and more than 85% had co-occurring medical conditions such as obesity, hyperlipidemia, or prediabetes. By the end of the study, none met criteria for metabolic syndrome.

On average, participants experienced a 10% reduction in weight and BMI. Waist circumference was reduced by 11%, fat mass index dropped by 17%, and systolic blood pressure decreased by 6%. In addition, metabolic markers including visceral fat, inflammation, A1c, and insulin resistance also improved. All outcomes were significant at P < .001 except for systolic blood pressure, at P < .005.

There was also a 20% reduction in triglycerides and a 21% increase in low-density lipoprotein cholesterol (both at P < .02). 

The study’s limitations include its small sample size, the lack of control arm, and short duration.

“Mental health and physical health are interconnected and addressing metabolic issues can complement psychiatric treatment to enhance overall well-being. Understanding the

mechanisms and potential synergies between psychiatric treatment and metabolic improvements can also inform the development of more effective interventions,” the researchers wrote. 

The study was funded by the Baszucki Group, Kuen Lau Fund, and the Obesity Treatment Foundation. The authors declare no competing interests.

Co-administration of a probiotic and vitamin D significantly improved cognitive function in patients with schizophrenia, results from a double-blind randomized controlled trial suggested.

The combination also led to favorable changes in total cholesterol, fasting blood sugar, and a marker of inflammation.

“Targeting the microbiota-gut-brain axis with probiotic and vitamin D might provide a novel approach to promote mental health,” investigators led by Gita Sadighi, MD, Department of Psychiatry, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran, wrote.

The study was published online in Neuropsychopharmacology Reports.
 

Cognitive Boost

The research includes data on 70 adults with schizophrenia who were on stable antipsychotic medication for at least 6 months. Half took a capsule containing five different probiotic strains plus 400 IU of vitamin D daily for 12 weeks, and half took a matching placebo capsule.

Primary outcomes were disease severity and cognitive function, measured at baseline, every 2 weeks during the trial, and again at the end of the study. Measurement tools included the Positive and Negative Syndrome Scale (PANSS) for disease severity and the 30-point Montreal Cognitive Assessment (MoCA) for cognitive function.

Secondary outcomes were lipid profile, body mass index, gastrointestinal problems, serum C-reactive protein (CRP), and erythrocyte sedimentation rate.

A total of 69 patients completed the trial, and no adverse effects were observed during the study period.

The marginal mean MoCA score increased by 1.96 units in the probiotic/vitamin D group compared with the placebo group during the study period, indicating significant improvement in cognitive function (P = .004).

In addition, the percentage of patients with a MoCA score of ≥ 26 (indicating normal cognition) increased significantly in the supplement group (P = .031), while there were no significant changes in the placebo group (P = .625).

The probiotic/vitamin D supplement was associated with a reduction in the PANSS score by 2.82 units compared with placebo, but the difference between groups was not statistically significant (P = .247).

The supplement group also saw a significant decrease in total cholesterol (P = .011), fasting blood sugar (P = .009), and CRP (P < .001).
 

Promising ‘Suggestive’ Evidence

Reached for comment, Roger McIntyre, MD, professor of psychiatry and pharmacology and head of the Mood Disorders Psychopharmacology Unit, University of Toronto, Toronto, Ontario, Canada, told this news organization that people living with schizophrenia have “significant impairment in general cognitive functions that can be debilitating and impair quality of life.”

This study provides “suggestive evidence” that the combination of probiotics and vitamin D is safe and effective in the treatment of cognitive dysfunction and “provides hope for persons with the lived experience. However, larger rigorous randomized control trials are needed to confirm these findings,” said Dr. McIntyre, who was not part of the study.

Also weighing in, Christopher M. Palmer, MD, assistant professor of psychiatry at Harvard Medical School in Boston, Massachusetts, noted that many researchers are focusing on the gut-brain connection and its role in a range of neuropsychiatric disorders, including schizophrenia.

“The gut microbiome appears to play a role in a range of factors that can impact brain function, including levels of inflammation, blood sugar, insulin signaling, and neurotransmitter production within the digestive tract,” said Dr. Palmer, who was not involved in the trial. “All of these factors can impact the brain, and in particular, brain metabolism, which increasingly is thought to play a key role in schizophrenia and other neuropsychiatric conditions.”

The new study builds on prior work in important ways, Dr. Palmer added. For example, he noted, earlier research did not show a benefit of probiotics alone.

“One of the challenges with probiotic research is the type of probiotic used. There are single-strain versions and multi-strain versions,” Dr. Palmer said. “This study used a probiotic containing five different bacterial species, so it’s possible that prior studies didn’t use the ideal type of probiotic. Combining the probiotic with vitamin D may also play a critical role.”

The new work replicates findings from a 2019 study in people with schizophrenia who received a four-strain probiotic plus vitamin D or a placebo for 12 weeks, he noted.

“The patients who got the probiotic plus vitamin D experienced improvement in psychiatric symptoms and improvement in three of the same biomarkers used in this study (reductions in total cholesterol, fasting blood sugar, and CRP),” Dr. Palmer said.

Like Dr. McIntyre, Dr. Palmer noted that larger clinical trials are needed before a treatment recommendation can be made.

“We also need to better understand which probiotics to use and the optimal dose of vitamin D supplementation,” he said. “In the meantime, however, patients may want to discuss this research with their clinicians to see if this might be something to consider in their own treatment.”

The study had no funding source. The authors and Dr. McIntyre had no relevant disclosures. Dr. Palmer is the author of the book Brain Energy published by Penguin Random House.

High-dose valproate is associated with weight gain in psychiatric patients, with the greatest gain reported in those taking ≥ 1300 mg/d, new data showed.

METHODOLOGY:

• The researchers used 1-year data from two longitudinal studies conducted between 2007 and 2022.
• The study included 215 patients (median age, 48 years; 50% female) who had been diagnosed with bipolar disorder (38%), schizoaffective disorders (26%), schizophrenia (17%), or other conditions (16%).
• The researchers used linear mixed-effect models and logistic regressions to analyze the association between doses of valproate and metabolic outcomes.

TAKEAWAY:

• Each 500-mg increase in valproate dose was associated with a weight increase of 0.52% per month over a year (P < .001), an association that was evident before and after 3 months of treatment.
• Weight gain was greatest for treatment durations of < 3 months (+0.56%, P < .001) compared with ≥ 3 months (+0.12%, P = .02).
• The greatest weight gain was observed in patients receiving doses ≥ 1300 mg/d, with a 0.50% increase in weight for each dose increment of 500 mg (P = .004).
• In men, each 500-mg dose was associated with an increase of 0.59%, while the trend in women was for an increase of 0.40% (P = .09).
• The researchers did not find associations between valproate doses and blood glucose, lipid levels, or blood pressure across a treatment period of 6 months.

IN PRACTICE:

“These findings underscore the need for clinicians to closely monitor patients on [valproate] for weight gain and to prescribe the lowest effective doses,” the authors wrote.

It was published online in the Journal of Clinical Psychiatry.

LIMITATIONS:

The study demonstrates an association, not causation. Treatment compliance could not be verified, although the daily dose administered to hospitalized patients was available. The study did not include information regarding lifestyle that could affect weight gain, such as dietary habits, physical activity, and substance use.

TOPLINE:

Black patients with schizophrenia are less likely to receive a clozapine prescription compared with White patients, a new study shows. The findings held even after the researchers controlled for demographic variables, social determinants of health, and care access patterns.

METHODOLOGY:

• The study drew on structured electronic health record data on 3160 adult patients with schizophrenia.
• The mean age at first recorded diagnosis was 39.5 years; 70% of participants were male, 53% Black, and 91% resided in an urban setting.
• The researchers used the social vulnerability index (SVI) to quantify social determinants of health.
• Descriptive data analysis, logistic regression, and sensitivity analysis were used to identify differences between those who received a clozapine prescription and those who were prescribed antipsychotic medications other than clozapine.

TAKEAWAY:

• Overall, 401 patients received a clozapine prescription, 51% of whom were White and 40% were Black.
• Moreover, 19% of all White patients in the study received clozapine vs 10% of Black patients.
• After the researchers controlled for demographic variables, SVI scores, and care patterns, White patients were significantly more likely to receive a clozapine prescription than Black patients (adjusted odds ratio [aOR], 1.71; P < .001).
• Factors that had a statistically significant influence on the likelihood of receiving a clozapine prescription were minority status and language (OR, 2.97; P < .007), treatment duration (OR, 1.36; P < .001), and socioeconomic status (OR, 0.27; P = .001).

IN PRACTICE:

“The reasons for the underprescription of clozapine among Black patients with schizophrenia are multifactorial and may include concerns about benign ethnic neutropenia, prescriber bias, prescribers’ anticipation of patients’ nonadherence to the treatment, and the notion that the medication is less effective for Black patients,” the authors wrote.

SOURCE:

Xiaoming Zeng, MD, PhD, professor of psychiatry, University of North Carolina, Chapel Hill, North Carolina, was the senior and corresponding on the study. It was published online on March 19 in Psychiatric Services.

LIMITATIONS:

Due to the study’s cross-sectional and single-site design, the findings may not be generalizable to other geographic areas or institutions. The study lacked information on substance use disorders, common health conditions, or other patient-level data. A question remains whether all patients who received clozapine actually had treatment-resistant schizophrenia because other research has shown that there is an overdiagnosis of schizophrenia among Black patients.

DISCLOSURES:

The study was supported by a grant from the Foundation of Hope. Dr. Zeng reported no relevant financial relationships. The other authors’ disclosures are listed on the original paper.

Images generated by photographic computer software are the first to depict accurate images of facial distortions experienced by patients with prosopometamorphopsia (PMO), a rare visual disorder that is often mistaken for mental illness.

PMO is a rare, often misdiagnosed, visual disorder in which human faces appear distorted in shape, texture, position, or color. Most patients with PMO see these distorted facial features all the time, whether they are looking at a face in person, on a screen, or paper.

For this study, investigators worked with a single patient, a 58-year-old man with a 31-month history of seeing what he describes as “demonic”-looking human faces. Unlike most cases of PMO, the patient reported seeing the distortions only when encountering someone in person but not on a screen or on paper.

This allowed researchers to use editing software to create an image on a computer screen that matched the patient’s distorted view.

“This new information should help healthcare professionals grasp the intensity of facial distortions experienced by people with PMO,” study investigator Brad Duchaine, PhD, professor, Department of Psychological and Brain Sciences, Dartmouth College, Hanover, New Hampshire, told this news organization.

“A substantial number of people we have worked with have been misdiagnosed, often with schizophrenia or some sort of psychotic episode, and some have been put on antipsychotics despite the fact they’ve just had some little tweak in their visual system,” he added.

The report was published online on March 23 in The Lancet.
 

Prevalence Underestimated?

Although fewer than 100 cases of PMO have been reported in the literature, Dr. Duchaine said this is likely an underestimate. Based on a response to a website his team created to recruit affected patients, he said he believes “there are far more cases out there that we realize.”

PMO might be caused by a neurologic event that leads to a lesion in the right temporal lobe, near areas of facial processing, but in many cases, the cause is unclear.

PMO can occur in the context of head trauma, as well as cerebral infarction, epilepsy, migraine, and hallucinogen-persisting perception disorder, researchers noted. The condition can also manifest without detectable structural brain changes.

“We’re hearing from a lot of people through our website who haven’t had, or aren’t aware of having had, a neurologic event that coincided with the onset of face distortions,” Dr. Duchaine noted.

The patient in this study had a significant head injury at age 43 that led to hospitalization. He was exposed to high levels of carbon monoxide about 4 months before his symptoms began, but it’s not clear if the PMO and the incident are related.

He was not prescribed any medications and reported no history of illicit substance use.

The patient also had a history of bipolar affective disorder and posttraumatic stress disorder. His visions of distorted faces were not accompanied by delusional beliefs about the people he encountered, the investigators reported.

Neuropsychological tests were normal, and there were no deficits of visual acuity or color vision. Computer-based face perception tests indicated mild impairment in recognition of facial identity but normal recognition of facial expression.

The patient did not typically see distortions when looking at objects, such as a coffee mug or computer. However, said Dr. Duchaine, “if you get enough text together, the text will start to swirl for him.”
 

Eye-Opening Findings

The patient described the visual facial distortions as “severely stretched features, with deep grooves on the forehead, cheeks, and chin.” Even though these faces were distorted, he was able to recognize the people he saw.

Because the patient reported no distortion when viewing facial images on a screen, researchers asked him to compare what he saw when he looked at the face of a person in the room to a photograph of the same person on a computer screen.

The patient alternated between observing the in-person face, which he perceived as distorted, and the photo on the screen, which he perceived as normal.

Researchers used real-time feedback from the patient and photo-editing software to manipulate the photo on the screen until the photo and the patient’s visual perception of the person in the room matched.

“This is the first time we have actually been able to have a visualization where we are really confident that that’s what someone with PMO is experiencing,” said Dr. Duchaine. “If he were a typical PMO case, he would look at the face in real life and look at the face on the screen and the face on the screen would be distorting as well.”

The researchers discovered that the patient’s distortions are influenced by color; if he looks at faces through a red filter, the distortions are greatly intensified, but if he looks at them through a green filter, the distortions are greatly reduced. He now wears green-filtered glasses in certain situations.

Dr. Duchaine hopes this case will open the eyes of clinicians. “These sorts of visual distortions that your patient is telling you about are probably real, and they’re not a sign of broader mental illness; it’s a problem limited to the visual system,” he said.

The research was funded by the Hitchcock Foundation. The authors reported no relevant conflicts of interest.

Patients receiving long-acting injectable (LAI) antipsychotics upon hospital discharge were 75% less likely to be readmitted 30 days later compared with those who received an oral antipsychotic, new research showed.

Investigators reported the findings support the use of LAI antipsychotics over oral medication following a hospital stay for schizophrenia or schizoaffective disorder.

“I suspect the lower readmission rate that has been observed with long-acting injections has more to do with people forgetting to take a pill each and every day than with any inherent superiority of the injectable medication,” lead author Daniel Greer, PharmD, BCPP, clinical assistant professor at Rutgers University Ernest Mario School of Pharmacy, Piscataway, New Jersey, said in a news release.

“Other studies on the use of antipsychotic medication have found that roughly three fourths of patients do not take oral medications exactly as directed, and it’s much easier to get a shot every few months than it is to take a pill every day, even though the shot requires a trip to the doctor,” Dr. Greer added.

The study was published online on January 17, 2024, in the Journal of Clinical Psychopharmacology.
 

Fewer Repeat Stays

Investigators compared 30-day readmission rates for all 343 patients with schizophrenia or schizoaffective disorder who were discharged from an inpatient psychiatric unit between August 2019 and June 2022.

A total of 240 patients (70%) were discharged on an oral antipsychotic, most commonly risperidone or olanzapine, and 103 (30%) were sent home on an LAI antipsychotic, most commonly aripiprazole lauroxil or haloperidol decanoate.

Within 30 days of discharge, 22 patients (6.4%) were readmitted for a schizophrenic or schizoaffective exacerbation — two in the LAI antipsychotic group and 20 in the oral antipsychotic group (1.9% vs 8.3%; P = .03).

The LAI antipsychotic group had a higher average daily chlorpromazine equivalent antipsychotic dose than the oral group (477.3 mg vs 278.6 mg; P < .001), which investigators said may indicate a difference in illness severity between the patient groups.

There was no significant between-group difference in the use of anticholinergic medications to treat extrapyramidal symptoms (22% in the LAI group and 31% in the oral group) despite the LAI group receiving greater doses.

That suggests “that both formulations may be equally as likely to cause these adverse effects,” the researchers noted.

Thirty-day readmission rates are important both medically and financially, investigators noted. In schizophrenia, access to medications and nonadherence are “significant problems.” LAI antipsychotic medications may alleviate some of these burdens but come with a high up-front cost.

“Medication access through pharmaceutical company free trial replacement programs may be an option for facilities with restricted formularies or limited medication funding to decrease 30-day readmissions,” investigators wrote.

“The cost of the injections is far lower than the cost of hospital treatments,” Dr. Greer added in the news release. “And each additional visit to the hospital increases the odds that there will be more visits in the future. Every time someone experiences psychosis, they lose gray matter, and they suffer damage that never heals. That’s why it’s so vital to minimize psychotic episodes.”

Chief limitations of the study included its single-center, retrospective chart review design and small sample size. Also, complete patient medication history was not obtained.

The study had no specific funding. The authors declared no relevant conflicts of interest.

Patients receiving long-acting injectable (LAI) antipsychotics upon hospital discharge were 75% less likely to be readmitted 30 days later compared with those who received an oral antipsychotic, new research showed.

Investigators reported the findings support the use of LAI antipsychotics over oral medication following a hospital stay for schizophrenia or schizoaffective disorder.

“I suspect the lower readmission rate that has been observed with long-acting injections has more to do with people forgetting to take a pill each and every day than with any inherent superiority of the injectable medication,” lead author Daniel Greer, PharmD, BCPP, clinical assistant professor at Rutgers University Ernest Mario School of Pharmacy, Piscataway, New Jersey, said in a news release.

“Other studies on the use of antipsychotic medication have found that roughly three fourths of patients do not take oral medications exactly as directed, and it’s much easier to get a shot every few months than it is to take a pill every day, even though the shot requires a trip to the doctor,” Dr. Greer added.

The study was published online on January 17, 2024, in the Journal of Clinical Psychopharmacology.
 

Fewer Repeat Stays

Investigators compared 30-day readmission rates for all 343 patients with schizophrenia or schizoaffective disorder who were discharged from an inpatient psychiatric unit between August 2019 and June 2022.

A total of 240 patients (70%) were discharged on an oral antipsychotic, most commonly risperidone or olanzapine, and 103 (30%) were sent home on an LAI antipsychotic, most commonly aripiprazole lauroxil or haloperidol decanoate.

Within 30 days of discharge, 22 patients (6.4%) were readmitted for a schizophrenic or schizoaffective exacerbation — two in the LAI antipsychotic group and 20 in the oral antipsychotic group (1.9% vs 8.3%; P = .03).
