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.

PEER simplified lipid guideline 2023 update: Prevention and management of cardiovascular disease in primary care.

OBJECTIVE: To update the 2015 clinical practice guideline and provide a simplified approach to lipid management in the prevention of cardiovascular disease (CVD) for primary care. METHODS: Following the Institute of Medicine's Clinical Practice Guidelines We Can Trust, a multidisciplinary, pan-Canadian guideline panel was formed. This panel was represented by primary care providers, free from conflicts of interest with industry, and included the patient perspective. A separate scientific evidence team performed evidence reviews on statins, ezetimibe, proprotein convertase subtilisin-kexin type 9 inhibitors, fibrates, bile acid sequestrants, niacin, and omega-3 supplements (docosahexaenoic acid with eicosapentaenoic acid [EPA] or EPA ethyl ester alone [icosapent]), as well as on 11 supplemental questions. Recommendations were finalized by the guideline panel through use of the Grading of Recommendations Assessment, Development and Evaluation methodology. RECOMMENDATIONS: All recommendations are presented in a patient-centred manner designed with the needs of family physicians and other primary care providers in mind. Many recommendations are similar to those published in 2015. Statins remain first-line therapy for both primary and secondary CVD prevention, and the Mediterranean diet and physical activity are recommended to reduce cardiovascular risk (primary and secondary prevention). The guideline panel recommended against using lipoprotein a, apolipoprotein B, or coronary artery calcium levels when assessing cardiovascular risk, and recommended against targeting specific lipid levels. The team also reviewed new evidence pertaining to omega-3 fatty acids (including EPA ethyl ester [icosapent]) and proprotein convertase subtilisin-kexin type 9 inhibitors, and outlined when to engage in informed shared decision making with patients on interventions to lower cardiovascular risk. CONCLUSION: These updated evidence-based guidelines provide a simplified approach to lipid management for the prevention and management of CVD. These guidelines were created by and for primary health care professionals and their patients.

Lipid-lowering therapies for cardiovascular disease prevention and management in primary care: PEER umbrella systematic review of systematic reviews.

OBJECTIVE: To assess the benefits and harms of lipid-lowering therapies used to prevent or manage cardiovascular disease including bile acid sequestrants (BAS), ezetimibe, fibrates, niacin, omega-3 supplements, proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors, and statins. DATA SOURCES: MEDLINE, the Cochrane Database of Systematic Reviews, and a grey literature search. STUDY SELECTION: Systematic reviews of randomized controlled trials published between January 2017 and March 2022 looking at statins, ezetimibe, PCSK9 inhibitors, fibrates, BAS, niacin, and omega-3 supplements for preventing cardiovascular outcomes were selected. Outcomes of interest included major adverse cardiovascular events (MACE), cardiovascular mortality, all-cause mortality, and adverse events. SYNTHESIS: A total of 76 systematic reviews were included. Four randomized controlled trials were also included for BAS because no efficacy systematic review was identified. Statins significantly reduced MACE (6 systematic reviews; median risk ratio [RR]=0.74; interquartile range [IQR]=0.71 to 0.76), cardiovascular mortality (7 systematic reviews; median RR=0.85, IQR=0.83 to 0.86), and all-cause mortality (8 systematic reviews; median RR=0.91, IQR=0.88 to 0.92). Major adverse cardiovascular events were also significantly reduced by ezetimibe (3 systematic reviews; median RR=0.93, IQR=0.93 to 0.94), PCSK9 inhibitors (14 systematic reviews; median RR=0.84, IQR=0.83 to 0.87), and fibrates (2 systematic reviews; mean RR=0.86), but these interventions had no effect on cardiovascular or all-cause mortality. Fibrates had no effect on any cardiovascular outcomes when added to a statin. Omega-3 combination supplements had no effect on MACE or all-cause mortality but significantly reduced cardiovascular mortality (5 systematic reviews; median RR=0.93, IQR=0.93 to 0.94). Eicosapentaenoic acid ethyl ester alone significantly reduced MACE (1 systematic review, RR=0.78) and cardiovascular mortality (2 systematic reviews; RRs of 0.82 and 0.82). In primary cardiovascular prevention, only statins showed consistent benefits on MACE (6 systematic reviews; median RR=0.75, IQR=0.73 to 0.78), cardiovascularall-cause mortality (7 systematic reviews, median RR=0.83, IQR=0.81 to 0.90), and all-cause mortality (8 systematic reviews; median RR=0.91, IQR=0.87 to 0.91). CONCLUSION: Statins have the most consistent evidence for the prevention of cardiovascular complications with a relative risk reduction of about 25% for MACE and 10% to 15% for mortality. The addition of ezetimibe, a PCSK9 inhibitor, or eicosapentaenoic acid ethyl ester to a statin provides additional MACE risk reduction but has no effect on all-cause mortality.

Lignes directrices simplifiées de PEER sur les lipides : actualisation 2023: Prévention et prise en charge des maladies cardiovasculaires en soins primaires.

OBJECTIF: Actualiser le guide de pratique clinique de 2015 et présenter une approche simplifiée de la prise en charge des lipides dans la prévention des maladies cardiovasculaires (MCV) en première ligne. MÉTHODES: Conformément aux recommandations de l'Institute of Medicine dans Clinical Practice Guidelines We Can Trust, un panel pancanadien d'experts multidisciplinaires en lignes directrices a été formé. Ce panel était représentatif des cliniciens en soins primaires, libre de tout conflit d'intérêts avec l'industrie, et il tenait compte des points de vue des patients. Une équipe distincte, responsable des données probantes scientifiques, a passé en revue l'information sur les statines, l'ézétimibe, les inhibiteurs de la proprotéine convertase subtilisine-kexine de type 9, les fibrates, les chélateurs des acides biliaires, la niacine et les suppléments d'omega-3 (acide docosahexaénoïque avec acide eicosapentaénoïque [EPA] ou ester éthylique de l'EPA seul [icosapent]), ainsi que sur la réponse à 11 questions supplémentaires. Le panel des lignes directrices a finalisé les recommandations en utilisant la méthodologie GRADE (Grading of Recommendations Assessment, Development and Evaluation). RECOMMANDATIONS: Toutes les recommandations sont présentées de manière à être centrées sur le patient et conçues en ayant à l'esprit les besoins des médecins de famille et des autres cliniciens des soins primaires. De nombreuses recommandations sont semblables à celles publiées en 2015. Les statines demeurent le traitement de première intention pour la prévention tant primaire que secondaire des MCV, et le régime méditerranéen et l'activité physique sont recommandés pour réduire le risque cardiovasculaire (en prévention primaire et secondaire). Le panel des lignes directrices a recommandé de ne pas utiliser le dosage des lipoprotéines a, des apolipoprotéines B ou le score calcique coronarien (SCC) dans l'évaluation du risque cardiovasculaire, et de ne pas cibler de seuils précis de taux lipidiques. L'équipe a aussi passé en revue de nouvelles données concernant les acides gras omega-3 (y compris l'ester éthylique d'EAP [icosapent]) et les inhibiteurs de la proprotéine convertase subtilisine-kexine de type 9, et a précisé les moments où il convient de procéder à une prise de décision partagée avec les patients sur les interventions pour diminuer le risque cardiovasculaire. CONCLUSION: Ces lignes directrices actualisées et fondées sur des données probantes présentent une approche simplifiée de la prise en charge des lipides pour la prévention et le traitement des MCV. Ce guide de pratique clinique a été conçu par et pour des professionnels de la santé en soins primaires et leurs patients.

Who provides chronic disease management? Population-based retrospective cohort study in Alberta.

OBJECTIVE: To determine the proportions of patients who receive care from family physicians, specialists, and nurse practitioners for the management of common chronic medical conditions. DESIGN: Population-based retrospective cohort study. SETTING: Province of Alberta. PARTICIPANTS: Adults aged 19 years or older who were registered for provincial health services and each had 2 or more interactions with the same provider between January 1, 2013, and December 31, 2017, for any of 7 specified chronic medical conditions: hypertension, diabetes, chronic obstructive pulmonary disease (COPD), asthma, heart failure, ischemic heart disease, and chronic kidney disease. MAIN OUTCOME MEASURES: Numbers of patients being managed for these conditions and which provider types were involved in their care. RESULTS: Albertans receiving care for the chronic medical conditions being studied (n=970,783) had a mean (SD) age of 56.8 (16.3) years and 49.1% were female. Family physicians were the sole providers of care for 85.7% of patients with a diagnosis of hypertension, 70.9% with diabetes, 59.8% with COPD, and 65.5% with asthma. Specialists were sole providers of care for 49.1% of patients with ischemic heart disease, 42.2% with chronic kidney disease, and 35.6% with heart failure. Nurse practitioners were involved in the care of less than 1% of patients with these conditions. CONCLUSION: Family physicians were involved in the care of most patients with any of 7 chronic medical conditions included in this study and were the sole providers of care for the majority of patients with hypertension, diabetes, COPD, and asthma. Guideline working group representation and the setting of clinical trials should reflect this reality.

Risk and distribution of chronic obstructive pulmonary disease-related hospitalizations among primary care patients.

OBJECTIVE: To determine the extent of chronic obstructive pulmonary disease (COPD) hospitalization in easily identifiable high-risk subgroups within a typical primary care practice. DESIGN: Prospective cohort analysis of administrative claims data. SETTING: British Columbia. PARTICIPANTS: British Columbia residents who were 50 years or older on December 31, 2014, and received a physician diagnosis of COPD between 1996 and 2014. MAIN OUTCOME MEASURES: Rate of acute exacerbation of COPD (AECOPD) or pneumonia hospitalization in 2015, broken down by risk identifiers including previous AECOPD admission, 2 or more community respirologist consultations, nursing home residence, or none of these. RESULTS: Of the 242,509 identified COPD patients (12.9% of British Columbia residents ≥50 years), 2.8% were hospitalized for AECOPD in 2015 (0.038 AECOPD hospitalizations per patient-year). The 12.0% with prior AECOPD hospitalization accounted for 57.7% of new AECOPD hospitalizations (0.183 hospitalizations per patient-year); the 7.7% with respirologist involvement accounted for 20.4% (0.102 hospitalizations per patient-year); and the 2.2% in nursing homes accounted for 3.6% (0.061 hospitalizations per patient-year). Those with any of the 3 risk identifiers accounted for only 1.5% more COPD hospitalizations (59.2%) than those with prior AECOPD hospitalization, suggesting prior AECOPD hospitalization is the most important indication of risk. A typical primary care practice held a median of 23 (interquartile range=4 to 65) COPD patients, of whom roughly 20 (86.4%) had none of these risk identifiers. This low-risk majority had only 0.018 AECOPD hospitalizations per patient-year. CONCLUSION: Most AECOPD hospitalizations occur in patients with previous such admissions. When time and resources are limited, COPD initiatives targeting primary care practices should focus more on the 2 to 3 patients with prior AECOPD hospitalization or more symptomatic disease, and less on the low-risk majority.
