Abstract

Background: A new policy was implemented in November 2021 to reduce the length of post-anesthesia-care-unit (PACU) stay from 6 hours to 4 hours to reduce the nursing care burden and decrease the length of stay, yet how it affected patients’ events after PACU discharge needed close evaluation. Thus, the QI project aimed to retrospectively examine unexpected or safety events of patients who underwent carotid artery stenting or carotid endarterectomy procedures before versus after implementing the new policy. Objective: To compare and examine the rates of unexpected or safety events that occurred before (5/1/2021 - 10/31/2021; PRE) vs. after (2/1/2022 - 7/31/2022; POST) adoption of the new policy. Methods: A determination of IRB review was granted for the retrospective QI project. The unexpected or safety events included patient issues (rapid response calls, STAT calls to service, or bounce back to a higher level of care) and issues with VS or neuro assessment variability. For group comparison, Fisher’s Exact tests were used for dichotomous information, and the Mann-Whitney U tests were performed for continuous data. Results: A total of 145 patients were identified during the study period composing 75 (51.7%) PRE and 70 (48.3%) POST patients. The rates of VS or neuro assessment variability were similar in both groups (PRE: 1.3% vs. POST: 1.3%, p =1.000). Though we saw a lower rate of patient issues within 24 hours on the floor in POST (4.3%), the difference was not statistically significant (PRE: 8.0%, p =0.496). Conclusion: Inefficient patient throughput can impact currently strained hospital resources. Findings of the QI project confirmed that the new policy did not incur a higher rate of instability on the nursing unit. This data lends confidence to Vascular Surgery and Stroke programs as they seek to streamline patient care and manage hospital resources.
