Quality of Diabetes Care Among the Canadian Regular Forces: A Retrospective Cohort Study

Abstract

The objective of the thesis was to evaluate the quality of diabetes care in the Canadian Forces by determining the extent to which physicians adhere to recommendations outlined in the 2008 Canadian Diabetes Association (CDA) clinical practice guidelines. In addition, the effect of patient age, sex, rank and size of base on quality of care was assessed and the accuracy of a diagnosis of diabetes in an extract of the electronic medical record (EMR) was evaluated. Fourteen bases within the Canadian Forces were selected for investigation, representing roughly half of the Canadian Forces population. Cases of diabetes were ascertained based on laboratory criteria following a chart review. Twenty-one CDA guideline recommendations were considered. The Canadian Forces demonstrated greater than 75% adherence with each of 9 recommendations, 50-75% adherence with each of 7 recommendations and less than 50% adherence with each of 5 recommendations. The overall adherence with all applicable recommendations per patient was 60.3% (SE 0.66). Age, sex, rank and size of base were not important factors influencing guideline adherence. The sensitivity of a diabetes diagnosis in an extract of the EMR was 84.5%, the specificity was 99.8%, the positive predictive value was 85.1% and the negative predictive value was 99.8%. This is similar to the performance of provincial and national diabetes registries. The quality of diabetes care in the Canadian Forces compared favourably with that of the civilian population within Canada and internationally. The creation of a diabetes registry is expected to lead to further improvements in diabetes care.
