Placard in Hand: A Simple, Inexpensive Intervention to Improve On-Treatment Visit Compliance in a Safety Net Radiation Oncology Patient Population.

PURPOSE: On-treatment visits (OTVs) for patients undergoing radiotherapy (RT) should occur every five fractions. Compliance with OTVs was identified as a potential issue in a safety-net patient population. This study determined if brightly colored placards given to patients improved OTV compliance. MATERIALS AND METHODS: A retrospective analysis of all patients with lung cancer receiving RT from October 1, 2015 to September 30, 2017 evaluated OTV compliance before (No Placard) and after (Placard) the placard was introduced in the clinic. Analysis of variance, χ2 tests, and Fisher's exact tests were performed to assess differences in continuous and categorical patient and treatment variables, respectively. RESULTS: The No Placard group included 48 patients who were scheduled for 151 OTVs. The Placard group included 50 patients who were scheduled for 187 OTVs. The percentage of missed OTVs in the No Placard group was 9.3% (14/151), versus 2.1% (4/187) in the Placard group (P = .004). Patients in the No Placard group were more likely to speak English (97.9% v 86.0%; P = .060), were less likely to have stage I-III disease (75% v 88%; P = .097), and received lower mean RT doses (48.2 Gy v 55.6 Gy; P = .007). On multivariate analysis adjusting for language, stage, and RT dose, the adjusted mean rate of missed OTVs in the No Placard group was 7.1%, versus 1.4% in the Placard group (P = .019). CONCLUSION: A significant increase in compliance of OTVs was observed with the introduction of brightly colored placards. This represents a simple, inexpensive method to improve OTV compliance in a safety-net setting and may be applicable to other patient populations.
