Top studies of 2023 relevant to primary care: From the PEER team.

OBJECTIVE: To provide a summary of the noteworthy medical articles published in 2023 that are relevant to family physicians. SELECTING THE EVIDENCE: Articles were chosen and ranked by the PEER (Patients, Experience, Evidence, Research) team, a group of primary care health professionals focused on evidence-based medicine. The selection process involved routine surveillance of tables of contents in high-impact medical journals and continuous monitoring of EvidenceAlerts. Articles were prioritized based on their direct applicability to and potential to influence primary care practice. MAIN MESSAGE: Selected articles addressed various clinical areas of primary care. The topics included a comparison of a treat-to-target approach versus a high-intensity statins prescription for lipid management; semaglutide and its impact on cardiovascular outcomes; respiratory syncytial virus vaccine for older adults; chlorthalidone versus hydrochlorothiazide in preventing cardiovascular events; amitriptyline for irritable bowel syndrome; the role of opioids in acute back pain; safety of oral penicillin challenges in patients allergic to penicillin; spironolactone for facial acne; strategies to reverse frailty in older adults; and identifying the provider of chronic disease management. Two "up and coming" medications are also mentioned: retatrutide for weight loss and fezolinetant for vasomotor symptoms of menopause. CONCLUSION: Research published in 2023 yielded several high-quality articles with topics relevant to primary care, including cardiovascular care, irritable bowel syndrome, care of the elderly, and acne management.
