Study Description

Brief Summary:

Missed health care appointments present a serious challenge to patient care. Especially in government funded health systems like that of Chile, missed appointments can lead to delayed care, wasted resources, and escalating costs.

This private-public-research collaboration seeks to provide a rigorous, practical evaluation of a new patient reminder system, evaluate how health beliefs impact patient attendance, and capture the potential for scaling up this or other health technology systems. Using a mixed-methods approach this study will provide contextualized, triangulated analysis of pediatric patient attendance in Chile.

Attendance	Behavioral: Health Call	Not Applicable

Detailed Description:

The Health Call study is divided into two phases. The first phase is a randomized controlled trial and side-by- side cost-benefit analysis. Enrolled guardians of pediatric patients will complete a questionnaire at the point of referral and then be randomized to intervention, the automated reminder system, or no reminder. The investigators will then monitor attendance status at their subsequent appointment and evaluate whether the appointment reminders affected attendance as well as the cost-benefit ratio of using the reminder system.

The second phase will involve interviewing guardians and healthcare professionals. These interviews have two foci. First, combined with patient, guardian, and/or household data from the randomized trial, these results will be used to develop a more comprehensive understanding of why pediatric patients attend appointments. The second focus is on improving the reminder system and developing new health technology interventions that can increase patient attendance.

Arms and Interventions

Arm	Intervention/treatment
No Intervention: No Intervention; The intervention arm subjects will not receive the automated interactive voice reminder before their appointment.
Experimental: Intervention; The intervention arm subjects will receive the automated interactive voice reminder before their appointment.	Behavioral: Health Call; Health Call is an automated interactive voice reminder system that can contact guardians of patients ahead of their child's appointment, asks then confirms a security question about the patient, then, if the call recipient passes the security screen, provides a reminder about upcoming appointment.

Outcome Measures

Primary Outcome Measures :

1. Intervention impact [ Time Frame: 9 months ]
   Evaluate whether a patient reminder system, Health Call, can decrease the overall failure to attend appointment rate as a percentage of overall appointments
2. Key attendance factors [ Time Frame: 9 months ]
   Examine what demographic or health belief factors are significantly related to appointment attendance as measured by a psychometric questionnaire
3. Develop new interventions [ Time Frame: 9 months ]
   Investigate staff and recipient opinions of patient attendance, the Health Call system, and ideas for future interventions to reduce failure to attend as measured through in-depth interviews
