Palliative Rehabilitation in Acute Inpatient Rehabilitation: Prognostic Factors and Functional Outcomes in Patients with Cancer

Background: Prognosis has a vital role for patients with cancer undergoing palliative rehabilitation in acute inpatient rehabilitation. This study aimed to identify the proportion of patients who survived <2 months after discharge and the associated prognostic factors. Materials and Methods: This was a secondary analysis of a retrospective study of 163 consecutive patients admitted to acute inpatient rehabilitation from September 1, 2017, to February 28, 2018 at a cancer center. Baseline demographics, clinical characteristics, and putative prognostic factors, including Activity Measure for Post-Acute Care (AM-PAC) functional scores, were analyzed. Results: Of 163 patients, 27 (17%; 95% CI, 11-23) died within 60 days of discharge. These patients were more likely to be male (OR = 2.83; 95% CI, 1.16-6.92; P = .017); have longer hospital stays (OR = 1.02; 95% CI, 1-1.04; P = .015); receive ≥ weekly packed red blood cell (OR = 5.31; 95% CI, 1.86-15.1; P = .003) or platelet (OR = 4.57; 95% CI, 1.44-14.5; P = .014) transfusions; have lower AM-PAC daily activity scores upon discharge (OR = 0.90; 95% CI, 0.83-0.97; P = .006); and have lower AM-PAC basic mobility scores upon admission (OR = 0.91; 95% CI, 0.85-0.98; P = .018) and discharge (OR = 0.88; 95% CI, 0.82-0.94; P = <.001). Multivariate analysis showed that the male sex (OR = 2.71; 95% CI, 1.03-7.15; P = .037) was independently associated with ≤2 months survival, whereas AM-PAC basic mobility score at admission of >33 (OR = 0.24, 95% CI, 0.07-0.79; P = .022) was less likely. Conclusion: Approximately 1 in 6 patients who completed acute inpatient rehabilitation died within 2 months of discharge, had poorer baseline functional status, and were less likely to regain function than those who lived longer.
