Background: Canada's growing immigrant population faces language and cultural barriers that hinder timely access to healthcare. The balance between elective and emergency general surgery (EGS) reflects immigrant's access to healthcare since many EGS cases are avoidable through treatment as elective procedures.
Objective: This study examines whether immigrants are more likely to undergo EGS than non-immigrants and measures whether language proficiency or access to primary care plays a role in disparity in access to care.
Methods: All general surgery procedures performed in British Columbia, Canada between 2013 and 2021 were identified using a population-based longitudinal administrative data that linked immigration data with physician billing and hospital data. The primary outcome was whether patients' surgery was elective or EGS and the primary exposure was immigrant status. The odds of EGS between immigrants and non-immigrants was estimated adjusting for patient and system-level differences. The analysis compared immigrants with and without English proficiency on arrival to Canada.
Results: Of 237,054 general surgery procedures, 30.7 % were EGS and 15.2 % involved immigrants. Immigrants had slightly higher odds of undergoing emergency general surgery (EGS) than non-immigrants. Immigrants not fluent in English had 16 % higher odds of EGS (OR: 1.16, 95 %CI 1.03-1.32). Immigrants with fewer GP contacts were more likely to undergo EGS (45.5 % versus 42.2 %, p < 0.01).
Conclusions: Immigrants with language barriers and who accessed primary care less often were more likely to require EGS. These findings highlight the need for system-level interventions to reduce immigrants' reliance on emergency surgical care.
Background: Prescription is a complex act that reflects the physician's expertise and authority. While some factors affecting prescription decisions have been studied, empirical findings often conflict, leaving our understanding of prescription behaviors limited and fragmented.
Objective: To assess the factors influencing physicians' drug prescribing habits by applying Strong Structuration Theory. Factors are categorized at: physician, practice, patient, industry, and system level.
Methods: Pubmed, Scopus, and ISI Web of Science were searched from inception to June 2025. Peer-reviewed studies were included if they were published in English, empirical, and assessed at least one factor influencing physicians' prescribing behaviors. Studies reporting the effect of covariates on prescriptions using Odds Ratios were included in the meta-analysis.
Results: 146 studies were selected for the review. At the macro-level, physicians were more likely to prescribe after being exposed to marketing activities by pharmaceutical industries, and for privately insured patients. Meso-level factors, such as practice ownership and setting, showed conflicting results, with no significant effect observed in the meta-analysis. Micro-level influences were the most prevalent in literature. Patient requests had a significant positive effect on prescriptions. Physician-level influences were inconsistent across most variables, except gender, where male physicians were more likely to prescribe. This effect was not confirmed by the meta-analysis, which showed heterogeneity across studies.
Conclusion: This study highlights the complexity of prescribing behaviors and the challenges in designing effective micro-level policies. Policymakers should therefore consider the multiple influences on prescribing to design targeted interventions that promote high-quality prescribing practices.
