Assessment of Capacity to Consent by Nurses Who Deliver Health Care to Patients Who Misuse Substances

This qualitative study explored the current practice that nurses use to assess capacity to consent to health care (CTC-HC) in street outreach settings. Key informant interviews were conducted with a purposive sample of nurses from each of British Columbia's five regional health authorities, allowing nurses to describe their lived experiences with assessing CTC-HC. Content analysis was used to summarize information captured in the data. A total of 19 nurses participated in the study. Five themes emerged from the data: (a) internal guiding forces that contribute to the nurses' assessment, (b) external influences that contribute to the nurses' assessment, (c) measures that are important for assessing CTC-HC, (d) threshold setting, and (e) context (physical and interpersonal) within which assessment of capacity takes place. These elements will be incorporated into a capacity assessment tool that can be used in nursing best practices.
