BackgroundThe Alberta Kidney Disease Network is a collaborative nephrology research organization based on a central repository of laboratory and administrative data from the Canadian province of Alberta.DescriptionThe laboratory data within the Alberta Kidney Disease Network can be used to define patient populations, such as individuals with chronic kidney disease (using serum creatinine measurements to estimate kidney function) or anemia (using hemoglobin measurements). The administrative data within the Alberta Kidney Disease Network can also be used to define cohorts with common medical conditions such as hypertension and diabetes. Linkage of data sources permits assessment of socio-demographic information, clinical variables including comorbidity, as well as ascertainment of relevant outcomes such as health service encounters and events, the occurrence of new specified clinical outcomes and mortality.ConclusionThe unique ability to combine laboratory and administrative data for a large geographically defined population provides a rich data source not only for research purposes but for policy development and to guide the delivery of health care. This research model based on computerized laboratory data could serve as a prototype for the study of other chronic conditions.

The use of rt-PA instead of heparin once weekly, as compared with the use of heparin three times a week, as a locking solution for central venous catheters significantly reduced the incidence of catheter malfunction and bacteremia. (Current Controlled Trials number, ISRCTN35253449.).

Background:The R x EACH trial was a randomized trial to evaluate the efficacy of community pharmacy-based case finding and intervention in patients at high risk for cardiovascular (CV) events. Community-dwelling patients with poorly controlled risk factors were identified and their CV risk reduced through patient education, prescribing and follow-up by their pharmacist. Perspectives of patients, family physicians and community pharmacists were obtained regarding pharmacists' identification and management of patients at high risk for CV events, to identify strategies to facilitate implementation of the pharmacist's expanded role in routine patient care. Methods:We used a qualitative methodology (individual semistructured interviews) with conventional qualitative content analysis to describe perceptions about community pharmacists' care of patients at high risk for CV events. Perceptions were categorized into macro (structure), meso (institution) and micro (practice) health system levels, based on a conceptual framework of care for optimizing scopes of practice. Results:We interviewed 48 participants (14 patients, 13 family physicians and 21 community pharmacists). Patients were supportive of the expanded scope of practice of pharmacists. All participant groups emphasized the importance of communication, ability to share patient information, trust and better understanding of the roles, responsibilities, accountabilities and liabilities of the pharmacist within their expanded role. Interpretation:Despite support from patients and changes to delivery of care in primary care settings, ongoing efforts are needed to understand how to best harmonize family physician and community pharmacist roles across the health system. This will require collaboration and input from professional associations, regulatory bodies, pharmacists, family physicians and patients. AbstractResearch Research CMAJ OPEN E206CMAJ OPEN, 5(1)
