Short-term effectiveness of inpatient cancer rehabilitation: A longitudinal controlled cohort study.

Background: Inpatient rehabilitation for cancer patients has been demonstrated to improve patients' health related quality of life (HRQoL) effectively. The purpose of this study was to compare changes in general health and HRQoL of cancer patients who were referred to inpatient rehabilitation (IR) with those in two control groups who underwent outpatient management either with advice for inpatient rehabilitation (A+ ) or without (A- ). Methods: In this naturalistic, longitudinal, controlled cohort study, changes in general health and HRQoL were assessed at either discharge of acute hospital or start of rehabilitation (baseline) and at the follow-up 3 weeks later or end of rehabilitation. Outcome variables included general health and HRQoL assessed by the Short Form 36 (SF-36) and the Functional Assessment of Cancer Therapy (FACT), and fatigue (FACT-F), depression and anxiety by the Hospital Anxiety and Depression Scale (HADS). Changes on the scores were compared with bivariate and multivariate analyses using standardized mean differences (SMD). Results: IR patients (n=133) were on average older, reported lower HRQoL and health, and suffered more frequently from carcinoma than patients of the A+ (n=30) and the A- (n=82) groups. In the IR patients, pain, physical functioning, mental health, vitality, and fatigue improved significantly compared to the A+ controls. Compared to the A- group, the bivariate effects were lower but still statistically significant on many scales. Conclusions: IR showed moderate, statistically significant superior effects over outpatient management of cancer patients after acute treatment. Findings indicate that inpatient cancer rehabilitation can be recommended as an effective management after acute treatment. As today, referrals to inpatient rehabilitation for cancer patients are still not based on structured standardized procedures, the implementation of such screening is needed to address patients' needs and to render the potential for rehabilitation more reliable.
