To detail the development of the Canadian National Questionnaire on Overdose Monitoring (CNQOM), a questionnaire aimed at assessing the perspectives of key stakeholders towards elements of overdose prevention interventions—supervised consumption sites (SCSs) and overdose hotlines and applications (ORHAs).

Cross-sectional survey.

Canadian health system.

English or French speaking adults from four key informant groups: people who use substances (PWUS), health professionals, emergency responders and the general public.

Test–retest reliability of CNQOM items.

A novel questionnaire was developed. Item development followed a standard approach, with face validity verified by representatives from the four informant groups. Input from experts in harm reduction and addiction medicine enhanced content and face validity of the questionnaire. A rigorous response validation approach was undertaken to ensure respondents were human and from Canada. Test–retest reliability items were assessed using Spearman’s rank correlation, Wilcoxon rank-sum test and Cohen’s kappa.

After data cleaning and response validation, 4445 valid responses were obtained from the four key informant groups. Respondents represented a range of sociodemographic backgrounds and housing scenarios from all provinces and territories in Canada. Test–retest reliability was assessed using a small subsample of 142 participants (primarily from general public informants). Questionnaire items demonstrated slight to substantial stability in responses (kappa coefficients: 0.15–0.58; Spearman’s r: 0.08–0.66).

The CNQOM is the first online questionnaire in Canada designed to capture perspectives and attitudes towards specific elements of SCSs and ORHAs among diverse key informant groups. Our questionnaire was administered to a large, geographically diverse sample and designed to capture the perspectives of four key informant groups. Lower than expected test–retest reliability may be explained by lack of participant familiarity with SCS and especially ORHAs and the impersonal nature of the instrument content among some respondents. Future work will elucidate key informant perspectives on these services based on the data.

Primary care nurses (PCNs) are the second largest workforce in primary care and play a critical role in facilitating access to coordinated care and reducing health disparities. There is renewed interest in team-based primary care as a solution for health workforce challenges. Some team models enable PCNs (ie, nurse practitioners, registered nurses, licensed/registered practical nurses) to leverage one another’s expertise to work to optimal scope; the extent to which this happens depends on multiple context-dependent factors. We will conduct an umbrella review to synthesise and compare international knowledge syntheses focused on scope of practice enactment (ie., roles and activities) of PCNs in primary care.

We will conduct the umbrella review according to the Joanna Briggs Institute methodology, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol (PRISMA-P) guidelines, and using the Nursing Care Organization Framework as guidance. We will search a wide range of scientific electronic databases and grey literature sources, and consider articles published in English and French by the Organization for Economic Cooperation and Development and designated key partner countries for inclusion, with no publication date limits. Two independent reviewers will screen titles, abstracts and full-text articles, and any disagreements will be resolved through discussion or by a third reviewer. We will use the Risk of Bias Assessment Tool for Systematic Reviews to assess the quality and risk of bias in the included systematic and scoping reviews.

Results will be presented in a PRISMA Scoping Review flow diagram. We will synthesise data from included studies in a detailed literature review table and develop visual aids to communicate the shared and unique roles and activities of PCN scope of practice. We will disseminate the results of the review through peer-reviewed publications and conferences related to this field. Ethics approval is not required.
