Implementation of clinical guidelines for adults with asthma and diabetes: a three‐year follow‐up evaluation of nursing care

Aims and objectives. To report on a three‐year follow‐up evaluation in Canada of nursing care indicators following the implementation of the Adult Asthma Care Best Practice Guideline and the Reducing Foot Complications for People with Diabetes Best Practice Guideline and to describe the contextual changes in the clinical settings. Background. The Registered Nurses’ Association of Ontario in Canada has developed and published more than 42 guidelines related to clinical nursing practice and healthy work environments.

Design. Longitudinal follow‐up study. Methods. Site observations and interviews were conducted with key informants at two hospitals.

Fisher exact tests were used to compare outcomes for the two time periods. Results. Three out of 12 indicators related to asthma care remained consistently high (≥84% of audited charts) and four indicators declined significantly (p
