An Evaluation of Patient Profiles and Outcomes in an Off-Site Rehabilitation Unit in 2023 Compared to 2019

Background Our off-site inpatient rehabilitation unit accepts patients from many different referral centres. Demographic shifts have occurred in the last 4 years with the Covid-19 pandemic resulting in several practice changes and frailty admissions increasing at our primary referral centre by 11%. We compared the number of patients, their demographics and dependency in 2023 in comparison with 2019 and hypothesised a longer length of stay could be explained by increased dependency as defined by Barthel score on admission. Methods Data regarding patients’ age, admission and discharge dates, referral source and discharge destination were extracted from the rehabilitation unit's database. Weekly MDT records were examined to identify the patients’ presentation and dependency level. Presentations were categorised as stroke, hip fracture, other fracture, acute medical and surgical presentations, and elective surgical procedures. Results Discharges decreased to 89 in 2023 compared to 125 in 2019. Mean length of stay increased to 35.1 from 29.5. Mean age reduced from 85 to 83. Mean Barthel on admission was unchanged at 10. 21 Patients were admitted following elective orthopaedic surgery in 2019 compared to 2 in 2023 with a mean length of stay of 16 days. Length of stay for stroke patients increased from 33 to 50. Excluding both led to a length of stay of 32 in both years. Conclusion The reduction of bed days could be explained by increased frequency of outbreaks and more robust isolation strategies reducing total bed availability. A significant reduction in patients admitted following elective orthopaedic surgery impacted the average length of stay as did an increase in length of stay for stroke patients. Patient dependency defined by Barthel score was not increased and did not explain the increased length of stay. A more comprehensive score such as the Rehabilitation Complexity Score may be more predictive of complexity and thus length of stay.
