Abstract WMP13: Implementation Issues Arising From Less-intense Monitoring In Routine Care: Process Evaluation Of The Optimial Post Rtpa-iv Monitoring In Acute Ischemic Stroke (OPTIMISTmain) Study

Background and Aims: OPTIMISTmain is an international, multicenter, stepped-wedge cluster randomized trial to determine effectiveness and safety of less-intensive versus standard monitoring in thrombolysis-treated patients with mild-moderate acute ischemic stroke. A process evaluation was undertaken to determine feasibility, acceptability, and impact of the intervention on care processes, experience and staffing. Methods: A sample of stroke care nursing managers and unit staff from 7 US sites were invited to participate in semi-structured interviews at an early stage of the study. Implementer clinician surveys were undertaken pre- and post-intervention to define integration of the intervention. Qualitative data were independently analyzed by 2 coders; survey data reported from descriptive analysis. Results: 19 nurses were interviewed from the units with 1:2 to 1:6 nurse-to-patient ratios. Less-intensive monitoring was well accepted: less time constraints and improved workload, and perceived to be cost efficient from improved use of neuro-intensive care beds. Some nurses had initial safety concerns over missing deteriorating patients. Less-intensive monitoring led to patients being less irritable and more cooperative from having more rest. There was greater flexibility in the allocation of nursing staff from workforce shortages arising due to the COVID pandemic. Similar results were evident in the survey (13 hospitals, 34 respondents): 80% of respondents agreed that less-intensive monitoring benefited work; 74% believed it should be widely adopted at a national level. Nurses reported time being freed up to provide more patient education (56%), continence/daily living care (50%), early mobilization (26%), mood/cognition assessment (44%), and other aspects (24%, e.g. communication, family support). Conclusions: Less-intensive monitoring after thrombolysis for acute ischemic stroke patients appears feasible and acceptable among US healthcare professionals.
