ProCare Trial: a phase II randomized controlled trial of shared care for follow-up of men with prostate cancer

Objectives: To test the feasibility and efficacy of a multifaceted model of shared care for men after completion of treatment for prostate cancer.

Patients and methods: Men who had completed treatment for low- to moderate-risk prostate cancer within the previous 8 weeks were eligible. Participants were randomized to usual care or shared care. Shared care entailed substituting two hospital visits with three visits in primary care, a survivorship care plan, recall and reminders, and screening for distress and unmet needs. Outcome measures included psychological distress, prostate cancer-specific quality of life, satisfaction and preferences for care and healthcare resource use.

Results: A total of 88 men were randomized (shared care n = 45; usual care n = 43). There were no clinically important or statistically significant differences between groups with regard to distress, prostate cancer-specific quality of life or satisfaction with care. At the end of the trial, men in the intervention group were significantly more likely to prefer a shared care model to hospital follow-up than those in the control group (intervention 63% vs control 24%; P<0.001). There was high compliance with prostate-specific antigen monitoring in both groups. The shared care model was cheaper than usual care (shared care AUS$1411; usual care AUS$1728; difference AUS$323 [plausible range AUS$91-554]).

Conclusion: Well-structured shared care for men with low- to moderate-risk prostate cancer is feasible and appears to produce clinically similar outcomes to those of standard care, at a lower cost.
