Usability of PCforMe in Patients With Advanced Cancer Referred to Outpatient Palliative Care: Results of a Randomized, Active-Controlled Pilot Trial.

CONTEXT: Low utilization of palliative care services warrant testing of new solutions to educate and engage patients around the benefits of palliative care. OBJECTIVES: We sought out to develop and test a novel, mobile health solution to prepare patients for an upcoming outpatient palliative care appointment. METHODS: After developing a web-based tool called PCforMe (Palliative Care for Me), we conducted a randomized, active-controlled, trial of PCforMe. The primary outcome was the score on the System Usability Scale (SUS). Secondary outcomes were patient self-efficacy and change in knowledge. We compared PCforMe to three common online resources for patients seeking information about palliative care. RESULTS: A total of 80 patients were randomized. There were no significant demographic differences. Mean SUS score for PCforMe was 78.2, significantly above the normative average SUS score of 68 (P-value < 0.0001). Mean change in Perceived Efficacy in Patient-Physician Interactions score was -2.2 for PCforMe and -1.7 for control group (P-value = 0.72). Preparedness for an upcoming palliative care visit increased 50% in the intervention group and 13.3% in the control group. Difference in the number of patients with improved knowledge regarding palliative care approached significance (P = 0.06). Lastly, we found that the no-show rate was lower during Q1 2017 (during trial) and Q1 2016 (before trial), at 11.7% and 21%, respectively (P < 0.05). Comparing the full calendar year (CY) 2016 with 2017, we did not find a statistical difference (CY 2016 of 18.8% and 15% in CY 2017; P = 0.22). CONCLUSION: PCforMe is a usable mobile health tool to prepare patients for an upcoming palliative care appointment. Further research is needed to test effectiveness.
