How short-term opioid prescriptions affect long-term outcomes
A recent article in CMAJ entitled Effect of emergency department opioid prescribing on health outcomes examines a key concern facing many clinicians: can a single opioid prescription for acute pain lead to long-term harm? This study aimed to clarify the risks and inform safer prescribing practices.Dr. Grant Innes, the study’s senior author, analyzed more than a decade of data from Alberta emergency departments to compare outcomes between patients who did and did not receive an opioid prescription. The study found no significant difference in rates of overdose, opioid use disorder, or death—challenging widely held fears about short-term opioid use. Innes notes that older and opioid-naive patients may be more vulnerable to adverse outcomes and encourages a balanced approach to pain management.Dr. Hance Clarke, director of pain services at Toronto General Hospital, emphasizes the importance of structured follow-up and monitoring, especially for patients at higher risk of persistent use. He outlines practical strategies for safe prescribing and highlights underused and emerging alternatives, including ketamine, IV lidocaine, nerve blocks, and sodium channel blockers now in development. Clarke warns against “opioid phobia” and calls for individualized care supported by systems that can detect early warning signs.The guests encourage physicians to not avoid prescribing opioids when clinically indicated, particularly in cases of severe acute pain. With thoughtful screening and mechanisms for follow-up, opioids can be relatively safe and effective. The goal is not zero prescribing, but safer, smarter prescribing.Comments or questions?

The mortality risk and therapeutic potential of hallucinogens
A research article in CMAJ examines mortality risk among people hospitalized for hallucinogen use. The study found that individuals who required acute hospital care for hallucinogen-related issues had a nearly fivefold increase in mortality risk compared to the general population.Dr. Daniel Myran, a public health and preventive medicine physician, family physician, and researcher at the University of Ottawa, discusses the study’s findings and why the growing perception of psychedelics as therapeutic may be influencing increased use. He explains how individuals hospitalized for hallucinogen-related issues often have additional risk factors, including other substance use and underlying health conditions, which may contribute to their elevated mortality risk.Dr. Ishrat Husain, a senior scientist and the scientific head of the clinical trials unit at CAMH in Toronto, explores the controlled medical use of hallucinogens in treatment-resistant depression. He outlines the intensive screening and psychological support involved in clinical trials and compares psilocybin therapy to other treatments such as electroconvulsive therapy (ECT) and ketamine. While early evidence is promising, Husain cautions that psilocybin remains experimental and requires significant resources, raising questions about its future accessibility.The findings highlight the need for clear public health messaging and policy decisions that distinguish between medical and recreational use of hallucinogens.For more information from our sponsor, go to md.ca/tax.

More access, more deaths: alcohol’s impact in the COVID-19 pandemic
A new CMAJ study has found that alcohol-related hospitalizations and deaths in Canada surged during the COVID-19 pandemic. While overall alcohol consumption increased only modestly, the toll on the healthcare system was severe, with a 14% rise in hospitalizations and a 24% increase in deaths during the first two years of the pandemic. Researchers suggest that increased access to alcohol—through expanded retail hours and home delivery—contributed to these harms, particularly among heavier drinkers.Dr. Tim Stockwell, a scientist at the Canadian Institute for Substance Use Research and an emeritus professor at the University of Victoria, discusses the study’s findings and why even a small rise in alcohol consumption can lead to a disproportionate increase in harm. He explains how heavier drinkers, already at risk, were pushed beyond critical health thresholds, contributing to the sharp rise in hospitalizations and deaths.Dr. Adam Sherk, a senior scientist at the Canadian Centre on Substance Use and Addiction, examines the policy decisions that shaped alcohol access during the pandemic. While economic considerations played a role, he notes that governments were also reluctant to introduce new restrictions on alcohol at a time when the public was already under significant strain. He argues that a more balanced approach is needed in future public health crises—one that allows reasonable access to alcohol but uses measures like increased pricing and decreased availability to moderate its impact on the healthcare system.The findings underscore the need to rethink how alcohol policy is handled during public health emergencies—not just in terms of balancing health and economic interests, but also in managing public willingness to accept restrictions in times of crisis.Comments or questions?

The major benefits of exercise for older adults
An article in CMAJ, "Move more, age well: prescribing physical activity for older adults," found that regular physical activity can reduce all-cause mortality by 31%. As Canada’s population ages, maintaining physical activity is becoming an increasingly critical factor in healthy aging. On this episode, Dr. Samir Sinha, a geriatrician at Sinai Health and the University Health Network and co-author of the CMAJ article, explains the evidence supporting exercise as a tool for preventing frailty, cognitive decline, and chronic disease in older adults. He addresses common misconceptions about aging and physical activity, emphasizing that even small, progressive increases in movement can help people stay independent longer.Physiotherapist Steve Di Ciacca, program manager at the Canadian Centre for Activity and Aging at Western University, outlines practical ways clinicians can help older patients build movement into their daily routines. He discusses the role of social engagement, personalized goal-setting, and structured exercise programs in improving adherence. He also highlights evidence showing that a simple written prescription for physical activity can increase adherence by up to 10%.This episode provides evidence-based insights to help clinicians encourage physical activity in older patients, promoting better long-term health outcomes.For more information from our sponsor, go to md.ca/tax.

Making healthcare accessible for patients with disabilities
Medicine remains frequently inaccessible to people with disabilities, despite their higher-than-average need for healthcare services. On this episode of the CMAJ Podcast, Dr. Blair Bigham and Dr. Mojola Omole tackle the systemic barriers that patients with disabilities face, from inaccessible clinic spaces to discriminatory attitudes.The discussion is inspired by the CMAJ practice article, "Five ways to support people who use wheelchairs," authored by Dr. Lisa Freeman. Dr. Freeman, a public health and preventative medicine physician who uses a wheelchair, shares her lived experiences navigating a healthcare system riddled with obstacles. She introduces practical steps that physicians can take to make their practices more inclusive, such as improving communication, ensuring referrals are effective, and addressing physical accessibility.David Lepofsky, chair of the Accessibility for Ontarians with Disabilities Act Alliance, explains the legal obligations that healthcare providers must meet to comply with human rights and accessibility laws. He offers actionable guidance on how physicians can reduce barriers, from small changes like posting signage to long-term planning for accessible infrastructure.This episode underscores that accessibility is both a legal requirement and a fundamental part of equitable patient care. It challenges physicians to take immediate steps toward making their practices more inclusive for patients with disabilities.Comments or questions?

Diagnosing and managing necrotizing fasciitis
On this episode of the CMAJ Podcast, Dr. Mojola Omole and Dr. Blair Bigham discuss necrotizing fasciitis, a diagnosis that can strike fear into the hearts of clinicians due to its rapid progression and devastating consequences. The discussion builds on insights from the CMAJ practice article, “Necrotizing soft tissue infections caused by invasive group A Streptococcus,” co-authored by Dr. Saswata Deb and Dr. Stephanie Mason.Dr. Deb, an emergency physician and clinician scientist at Sunnybrook Health Sciences Centre in Toronto, outlines the key clinical signs of necrotizing fasciitis, including pain out of proportion to physical findings and rapid hemodynamic deterioration. He emphasizes the importance of considering NSTI in the differential diagnosis for cellulitis and the need for prompt surgical consultation when red flags arise. Crucially, Dr. Deb explains that no imaging or laboratory tests can definitively rule in or rule out the diagnosis—only surgical exploration can confirm it.Dr. Mason, a burn and general surgeon at Sunnybrook’s Ross Tilley Burn Centre, provides a surgeon’s perspective on managing these infections. She addresses common missteps in diagnosis, the need for aggressive surgical debridement, and the role of multidisciplinary care in saving patients’ lives. She also discusses how surgeons can overcome their fear of creating extensive wounds, reassuring listeners that reconstruction is possible once the patient is stabilized.Together, the guests and hosts explore practical solutions to reduce delays in care, including the potential for institutional protocols—possibly a "code nec fasc"—to streamline decision-making and improve outcomes.For more information from our sponsor, go to md.ca/tax.

ENCORE: AI versus physicians: who’s better at spotting high-risk patients?
On this encore episode of the CMAJ Podcast, Dr. Blair Bigham and Dr. Mojola Omole discuss how artificial intelligence (AI) significantly improves the identification of hospital patients at risk of clinical deterioration compared to physician assessments alone. They are joined by Dr. Amol Verma, a general internist at St. Michael’s Hospital in Toronto, an associate professor at the University of Toronto, and the holder of the Temerty Professorship in AI Research and Education, who shares findings from his recent CMAJ article, “Clinical evaluation of a machine learning-based early warning system for patient deterioration”.Dr. Verma explains how the AI system, ChartWatch, analyzes over 100 variables from a patient’s electronic medical record to predict deterioration more accurately than traditional early warning scores like the NEWS score. He discusses how the integration of AI into clinical workflows improves patient outcomes by complementing human decision-making, leading to better results than relying on physicians or AI alone.The episode also looks at the potential future of AI in medicine, with Dr. Verma sharing insights on how AI tools should be thoughtfully integrated to support clinicians without overwhelming them. He stresses the need for AI systems to fit seamlessly into clinical workflows, ensuring patient care remains the priority. While AI is currently a tool to assist clinicians, Dr. Verma argues that the full extent of AI's role in healthcare—and its impact on the physician's place within it—remains ultimately unknowable.Comments or questions?

Misdiagnosed and misunderstood: premenstrual dysphoric disorder
On this episode of the CMAJ Podcast, Dr. Mojola Omole and Dr. Blair Bigham explore Premenstrual Dysphoric Disorder (PMDD), a debilitating condition affecting 5% of people who menstruate, yet it is often misdiagnosed or misunderstood. The conversation builds on insights from the CMAJ article, “Five things to know about…: PMDD,” co-authored by Dr. Erin Brennand, an associate professor at the Cumming School of Medicine in Calgary.Abhi Bala shares her lived experience with PMDD, describing the profound impact of cyclical depressive symptoms, suicidal ideation, and emotional dysregulation on her life. Her journey from misdiagnosis to awareness highlights the importance of tracking symptoms and recognizing patterns linked to the menstrual cycle, which can lead to earlier diagnosis and treatment.Dr. Brennand explains how PMDD is frequently mistaken for depression or bipolar disorder, delaying accurate diagnosis and treatment. She highlights the importance of recognizing that PMDD's cyclical symptoms align specifically with the luteal phase—the final two weeks of the menstrual cycle. Dr. Brennand also discusses evidence-based treatments, including SSRIs, oral contraceptives, and, in severe cases, GnRH agonists.This episode provides valuable insights into diagnosing and managing PMDD, helping physicians better support their patients.For more information from our sponsor, visit rainbowhealthontario.caComments or questions?
