OBJECTIVE: To examine the level of adherence to best-practice guidelines of interprofessional teams with acute care nurse practitioners (ACNPs) compared to interprofessional teams without ACNPs.
METHODS: A retrospective observational study was conducted in 2023.
METHODS: A retrospective cohort was created including 280 patients who underwent a coronary artery bypass graft and/or a valve repair and hospitalised in a cardiac surgery unit of a university affiliated hospital in Québec (Canada) between 1 January 2019 to 31 January 2020. The level of adherence to best-practice guidelines was measured from a composite score in percentage. The composite score was created from a newly developed tool including 99 items across six categories (patient information, pharmacotherapy, laboratory tests, post-operative assessment, patient and interprofessional teams\' characteristics). Multivariate linear and logistic regression models were computed to examine the effect of interprofessional teams with ACNPs on the level of adherence to best-practice guidelines.
RESULTS: Most of the patients of the cohort were male and underwent a coronary artery bypass graft procedure. Patients under the care of interprofessional teams with ACNP were 1.72 times more likely to reach a level of adherence higher than 80% compared to interprofessional teams without ACNPs and were 2.29 times more likely to be within the highest quartile of the scores for the level of adherence to best-practice guidelines of the cohort.
CONCLUSIONS: This study provides empirical data supporting the benefits of ACNP practice for patients, interprofessional teams and healthcare organisations.
CONCLUSIONS: Our findings identify the important contributions of interprofessional teams that include ACNPs using a validated instrument, as well as their contribution to the delivery of high quality patient care.
UNASSIGNED: This study followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Statement: Guidelines for reporting observational studies guidelines.
UNASSIGNED: No patient or public contribution.

UNASSIGNED: To improve patient outcomes many healthcare organizations have undertaken a number of steps to enhance the quality of care, including the use of evidence-based practices (EBPs) such as clinical practice guidelines. However, there is little empirical understanding of the longer-term use of guideline-based practices and how to ensure their ongoing use. The aim of this study was to identify the determinants and knowledge translation interventions (KTIs) influencing ongoing use of selected recommendations of an institutional pain policy and protocol over time from an organizational perspective and 10 years post implementation on two units within an acute care setting.
UNASSIGNED: We conducted a mixed methods case study guided by the Dynamic Sustainability Framework of an EBP 10 years post implementation. We examined protocol sustainability at the nursing department and unit levels of a multi-site tertiary center in Canada. Data sources included document review (n = 29), chart audits (n = 200), and semi-structured interviews with nurses at the department (n = 3) and unit (n = 16) level.
UNASSIGNED: We identified 32 sustainability determinants and 29 KTIs influencing ongoing use of an EBP in acute care. Three determinants and eight KTIs had a continuous influence in all three time periods: implementation phase (0-2 yrs), sustained phase (>2-10 yrs.), and at the 10-year mark. Implementation of KTIs evolved with the level of application (e.g., department vs. unit) to fit the EBP within the context highlighting the need to focus on determinants influencing ongoing use. Sustainability was associated with continual efforts of monitoring and providing timely feedback regarding adherence to recommendations. KTIs used to embed recommendations into routine practices/processes positively influenced high adherence rates. Use of a participatory approach for implementation and sustainment and linking KTIs designed to incrementally address low adherence rates facilitated sustainment.
UNASSIGNED: This research provides insight into the relationship between implementation and sustainability determinants and related KTIs during implementation and sustained use phases. Unique determinants identified by department and unit nurses reflect their different perspectives toward the innovation based on their respective roles and responsibilities. KTIs fostered changed behaviors and facilitated EBP sustainment in acute care. Findings confirm the concept of sustainability is a dynamic \"ongoing process.\"
