(Press-News.org) People who initiate a premature or “before medically advised” (BMA) hospital discharge have a 10-fold increase in the risk of drug overdose in the following month, according to new research in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.240364.
Patients leave hospital prematurely for a range of reasons, including improperly treated pain, cravings, stress that accentuates psychiatric issues, conflicts with hospital staff, and restrictions on movement or visitors. Hospital patients who initiate a BMA discharge are up to 3 times more likely to die in the following year than people who undergo routine physician-advised discharge. “Before medically advised” discharge has also been called “patient-initiated” or “against medical advice” discharge.
“For a long time, front-line doctors and nurses have wondered if BMA discharge increases subsequent overdose risk,” says Dr. John Staples, study senior author and a clinical associate professor at the University of British Columbia in Vancouver, BC. “For patients with substance use disorder, a long hospital stay can sometimes be a period of drug abstinence, potentially reducing opioid tolerance and interrupting access to [addiction] treatments. After these patients leave hospital, persistent pain and untreated addiction might prompt heavier-than-usual drug use. All these factors can increase the risk of subsequent overdose.”
To understand the link between BMA discharge and drug overdose, researchers conducted a study that examined health data on 189 808 hospital admissions occurring between 2015 and 2019 in British Columbia, Canada. A total of 6440 (3.4%) of these admissions ended with patients leaving hospital against medical advice. They found that patients with a BMA discharge were more likely to be younger males with psychiatric illness, substance use disorder, or a history of illicit drug use. The rate of fatal or nonfatal illicit drug overdose in the first 30 days after departure from hospital was 10 times higher after BMA discharge than after physician-advised discharge. “Before medically advised” discharge was associated with subsequent overdose even after accounting for other risk factors for overdose.
“These findings indicate that patients initiating a BMA discharge are at high risk of overdose, that BMA discharge may be a causal contributor to subsequent overdose, and that patients initiating a BMA discharge (especially those with a history of substance use disorder) should be offered urgent clinical and social supports to reduce overdose-related harms,” write the authors.
They suggest there are opportunities to improve medical care for these patients.
“Hospitals and health systems should develop evidence-based protocols to prevent BMA discharge and should explore novel means of postdeparture outreach to reduce the risk of drug overdose after hospital discharge,” the authors advise.

Study shows alcohol-dependent men and women have different biochemistries, so may need different treatments
2024-09-22
MILAN — A new study reveals hormonal and biochemical factors that affect alcohol dependence (also known as Alcohol Use Disorder), suggesting that men and women with alcohol problems may benefit from different treatments.
Scientists have known that men and women have different risks related to alcohol misuse and related problems and that alcohol treatments may need to be tailored differently to men and women. However, the biological mechanisms underlying those differences are not well understood.
"This is the first large study to confirm that some of the variability in Alcohol Use Disorder (AUD) and related ...
Researchers find that Antidepressants may improve brain function
2024-09-22
Researchers have found that SSRI (Selective Serotonin Reuptake Inhibitors) antidepressants have the potential to improve certain cognitive functions, such as verbal memory. They measured brain function in patients before and after taking the SSRI escitalopram and correlated this to a drop in the level of one of the serotonin receptors in the brain and to cognitive improvements during treatment. This work is presented for the first time at the ECNP Conference in Milan, after recent publication in the journal Biological Psychiatry.
Serotonin is often described as a ‘feel good’ chemical, and higher levels of serotonin circulating in the brain contribute to a sense of well-being, ...
Aviation can achieve Net-Zero by 2050 if immediate action is taken, says University of Cambridge report
2024-09-22
Cambridge University has today released a groundbreaking report outlining a five-year roadmap to help the aviation sector achieve net-zero climate impact by 2050.
Despite ambitious pledges from governments and industry, the aviation sector remains significantly off course in its efforts to achieve net-zero emissions by 2050. The report, titled “Five Years to Chart a New Future for Aviation,” outlines four 2030 Sustainable Aviation Goals—specific, actionable steps that must be initiated immediately and completed within five years if the aviation sector is to be on track to achieve net-zero by 2050.
The 2030 Goals outlined in the report are:

Study shows psychedelic drug psilocybin gives comparable long-term antidepressant effects to standard antidepressants, but may offer additional benefits
2024-09-22
A direct comparison between the experimental psychedelic drug psilocybin and a standard SSRI antidepressant shows similar improvement of depressive symptoms, but that psilocybin offers additional longer-term benefits.
The comparison, between psilocybin (the active ingredient in “magic mushrooms”) and the SSRI escitalopram gave similar long-term improvements in depressive symptoms over a 6-month period, however patients taking psilocybin also reported better psychosocial functioning including experiencing a greater sense of meaning ...
Study finds symptoms of depression during pregnancy linked to specific brain activity: scientists hope to develop test for “baby blues” risk
2024-09-21
Milan, Italy: Around 80% of women suffer from “baby blues” after the birth of their child. Normally this is a brief period of feeling down which disappears in a few days. But around 1 woman in 7 develops postpartum depression; this is a more serious depression which can affect how mothers bond with their baby and can have long-term consequences. These women seem unable to regulate the negative emotions which can follow giving birth.
Now a group of European Reesearchers have found that in healthy pregnant women activity in a specific area deep in the brain is linked to regulation of negative ...
Sexual health symptoms may correlate with poor adherence to adjuvant endocrine therapy in Black women with breast cancer
2024-09-21
LOS ANGELES – Among patients with early-stage breast cancer treated with adjuvant endocrine therapy (AET), symptoms related to sexual health were associated with decreased adherence to treatment in Black women, according to results presented at the 17th AACR Conference on the Science of Cancer Health Disparities in Racial/Ethnic Minorities and the Medically Underserved, held September 21-24, 2024.
Patients with hormone receptor-positive breast cancer are commonly given endocrine therapy—treatments that block estrogen signaling in the breast—after receiving surgery, radiation, or chemotherapy. The recommended regimen for AET ...
Black patients with triple-negative breast cancer may be less likely to receive immunotherapy than white patients
2024-09-21
LOS ANGELES – In recent years, Black patients with triple-negative breast cancer (TNBC) received immunotherapy at significantly lower rates than white patients, according to results presented at the 17th AACR Conference on the Science of Cancer Health Disparities in Racial/Ethnic Minorities and the Medically Underserved, held September 21-24, 2024.
Black women are disproportionately affected by TNBC, an aggressive subtype of breast cancer defined by the lack of three cell surface receptors. The absence of these receptors means that patients with TNBC are ineligible for many of the molecularly targeted therapies used to treat other breast cancer subtypes, explained ...
