Rehabilitation and functional outcomes of COVID-19 patients in a rehabilitation hospital in Qatar.

Background: Patients recovering from severe COVID-19 infections have experienced prolonged cognitive, physical, and psychological sequelae, including cardiorespiratory and motor deconditioning, neurological deterioration, anxiety, and depression. The impact of rehabilitation post-acute COVID-19 infection was recognized in the literature, but studies assessing and quantifying specific functional outcomes were lacking. This study aims to describe the characteristics and quantify the changes in functional outcomes of patients admitted to Qatar Rehabilitation Institute (QRI) for inpatient rehabilitation (IPR) post-COVID-19 infection during a 10-month period in 2021. Methods: This is a retrospective observational cohort study, which included individuals over 18 years of age with a documented COVID-19-positive diagnosis who were admitted to QRI for IPR due to COVID-19 complications. Data was collected by the investigators from January 1, 2021, until October 30, 2021. A total of 243 patients were included in this study. The changes in functional rehabilitation outcomes were assessed and quantified at both the patient's baseline (on admission to QRI) and after completion of IPR (on discharge). The duration of the IPR program varied based on each patient's baseline assessment. Patients were given a total of 8-12 weeks to achieve their rehabilitation goals and were discharged once those goals were met. Several validated tools were utilized in this study including Functional Independence Measure (FIM), Berg Balance Scale (BBS), Dynamic Gait Index (DGI), Modified Medical Research Council (mMRC) Dyspnea Scale, Mini-Mental State Examination (MMSE), and Right- and left-Hand Grip Strength. In addition, patients' diet, the need for respiratory support, and the presence of a tracheostomy tube before and after IPR were also recorded. Results: In total, 84.4% of the included patients were males (n = 205); with a mean age of 52.44 ± 12.99 years. The most commonly reported comorbidities were type 2 diabetes (62.1%) and hypertension (49.8%) with 83.5% of patients experiencing critical illness neuromyopathy. The average patients' length of stay in QRI was 33.92 ± 27.72 days. A statistically significant improvement in all functional outcome scales was noted following the completion of the IPR program ( Conclusion: IPR following COVID-19 infection was associated with significant functional, motor, and cardiorespiratory improvement. Dedicating clinics for post-COVID-19 rehabilitation would ensure improved patient outcomes and enhanced recovery.
