No Evidence on Association Between Prospective Exposure to Out-of-Pocket Cost Information and Appointment Cancelations or No-Shows: A Case-Control Pilot Study.

Health care price transparency aims to empower patients to make better-informed purchasing decisions. However, the prospective availability of patients' out-of-pocket costs may lead to an increased rate of forgone care. The objective of this study was to examine whether obtaining a prospective out-of-pocket cost estimate is associated with the likelihood of canceling or not arriving at a scheduled outpatient health care appointment. We surveyed adult individuals with scheduled outpatient imaging appointments at a large health care system in Georgia. In this case-control pilot study, we estimated the adjusted association between obtaining an out-of-pocket cost estimate for a scheduled imaging appointment (did not obtain an estimate, did not seek an estimate but received it via an unsolicited phone call from the health care system, and actively sought and obtained an estimate) and not attending the appointment using multivariable logistic regression that controlled for the type of primary health insurance and patient demographics. Actively seeking an out-of-pocket cost estimate was not associated with appointment cancelation or no-show (adjusted odds ratio [aOR] = 0.81, P = .75). Passively receiving an out-of-pocket cost estimate via an unsolicited phone call from the health care system was marginally associated with lower odds of appointment cancelation or no-show (aOR = 0.24; P = .076). This study did not find evidence of an association between prospective exposure of patients to out-of-pocket cost information and the likelihood of health care appointment cancelation or no-show.
