[Effects of a Phone-Based Follow-Up Care After Inpatient Rehabilitation for Breast Cancer Patients - A Randomized Controlled Trial].

Background Benefit and long-term effects of rehabilitation and psychoeducational interventions after cancer therapy are still controversial discussed. Aim of the study was to evaluate feasibility and effects of a telephone-based follow-up intervention after oncological rehabilitation. Methods 172 breast cancer patients (age 27-54 years) were randomized after inpatient rehabilitation to a telephone-based intervention (phone calls every 4 weeks over 6 months) or control group. Patients were evaluated by standardized questionnaire (e. g. IRES-24, HADS, LZI, emotional thermometer, questionnaire "return to work") at T1 (start of rehabilitation), T2 (end of rehabilitation) and T3 (6 months after rehabilitation). Results 2-way-ANOVAs were performed to evaluate long-term effects. Main effects of IRES-24 and HADS were significant depending on time (IRES-24 F(2,116)=40.49, p<0.01 and HADS F(2,117)=31.50, p<0.01; (F(2,11 6)=31.19, p<0.01) but no significant differences between the intervention and control group were seen. Conclusions Telephone-based follow-up care is feasible with high patient acceptance. However an improvement of therapeutic effects in the intervention group were not be detected by IRES-24 and HADS questionnaire. Potential explanations may be the low "dosage" (duration/quantity of phone calls) of the intervention or the fact that in the last years multimodal treatment interventions were established in German rehabilitation centers leading to a so-called "ceiling effect" without significant effects of additional follow-up interventions.
