Purpose: Primary care access is a key health system metric, but little research has compared models to provide primary care access when one's regular physician is not available. We compared health system use after a visit with a patient's own family physician group (ie, within-group physician who was not the patient's primary physician) vs a visit with a walk-in clinic physician who was not part of the patient's family physician group.

Methods: We conducted a population-based, retrospective cohort study using administrative data from Ontario, Canada, including all individuals formally enrolled with a family physician, from April 1, 2019 to March 31, 2020.

Background: The transition from pediatric to adult care is a vulnerable time for young people living with type 1 diabetes (T1D). Bridging the Gap (BTG) is an audit-and-feedback (AF) intervention aimed at improving both transitions-in-care processes and diabetes management in the year following transition. As part of BTG, we conducted a qualitative process evaluation to understand: (a) what was implemented and how; and (b) the contextual factors (micro-, meso- and macro-) that affected implementation, outcomes and study processes.

Article Synopsis
  • Opioids, while commonly prescribed for pain management, pose safety risks; the study explores whether strategies like audit and feedback can improve prescription practices among primary care physicians in Ontario.
  • The research used a matched-cohort design to compare the effects of audit and feedback, with or without academic detailing, on opioid prescribing rates over a 30-month period, focusing on family physicians.
  • Results indicated a general decline in opioid prescriptions pre-intervention across all groups, with significant reductions in high-prescribing physicians in the audit and feedback group, but no notable difference post-intervention between the groups, suggesting future efforts should target high-volume prescribers.

Background: Unnecessary antibiotic prescriptions in primary care are common and contribute to antimicrobial resistance in the population. Audit and feedback (A&F) on antibiotic prescribing to primary care can improve the appropriateness of antibiotic prescribing, but the optimal approach is uncertain. We performed two pragmatic randomized controlled trials of different approaches to audit and feedback.

Background: Damage from insect herbivores can elicit a wide range of plant responses, including reduced or compensatory growth, altered volatile profiles, or increased production of defence compounds. Specifically, herbivory can alter floral development as plants reallocate resources towards defence and regrowth functions. For pollinator-dependent species, floral quantity and quality are critical for attracting floral visitors; thus, herbivore-induced developmental effects that alter either floral abundance or attractiveness may have critical implications for plant reproductive success.

Herbivory is a major fitness pressure for plants and a key driver of crop losses in agroecosystems. Dense monocultures are expected to favor specialist herbivorous insects, particularly those who primarily consume crop species; yet, levels and types of herbivory are not uniform within regional cropping systems. It is essential to determine which local and regional ecological factors drive variation in herbivory in order to support functional agroecosystems that rely less on chemical inputs.
