There are concerns that alternate payment plans for physicians may be associated with erosion of data quality, given that physicians are paid regardless of whether claims are submitted. Our objective was to determine the proportion of claims submitted by physician specialists using fee-for-service and alternative payment plans, and to identify and compare the validity of information coded in physician billing claims submitted by these specialists in Calgary. ⋯ Overall submission rates and accuracy in recording diagnoses by physicians who used both plans were high. These findings show that the implementation of alternative payment plan programs in Alberta may not have an impact on the quality of physician claims data.

Hypothermia can result from exposure to cold or as a consequence of underlying physiologic vulnerabilities. Who, where, when and how British Columbians (and Canadians) die of hypothermia have received little research attention. The objective of this study was to describe the epidemiology of mortality due to hypothermia among residents of British Columbia. ⋯ Our results showed that older people are at higher risk of hypothermia-related death. Among residents of British Columbia who died of hypothermia, the most frequent additional causes of death were alcohol and nonalcohol psychoactive substances. However, further assessment of both the occurrence and determinants of mortality due to hypothermia are needed to inform measures to reduce its impact.

The use of prasugrel or ticagrelor as part of dual antiplatelet therapy with acetylsalicylic acid after acute coronary syndrome (ACS) improves clinical outcomes relative to clopidogrel. The relative cost-effectiveness of these agents are unknown. We conducted an economic analysis evaluating 12 months of treatment with clopidogrel, prasugrel or ticagrelor after ACS. ⋯ Ticagrelor was the most cost-effective agent when used as part of dual antiplatelet therapy after ACS. This conclusion was robust to wide variations in model parameters.
