Abstract
The Government of Khyber Pakhtunkhwa, Pakistan established a fully-subsizidised health insurance program covering inpatient hospital services in 2015. The government is currently piloting an extension of the program to selected outpatient services for the poorest households in one district. Households might face awareness challenges related to eligibility, registration, service coverage, and utilization of insurance benefits of the new outpatient insurance.

This study employs a randomized controlled design to assess whether targeted phone-based information provision can improve insurance awareness and subsequent program use. Households are randomly assigned to receive informational text messages and automated voice calls or to a control group receiving no intervention. The text messages and voicecalls convey standardized information on outpatient insurance entitlements and reference nearby empaneled health facilities.

Outcomes are measured using a midline phone survey and an endline in-person household survey. Primary outcomes include awareness of the new outpatient insurance, knowledge of insurance coverage, registration status, and health care utilization.

Interventions

Intervention(s)
The intervention consists of a series of informational messages delivered to households via SMS and automated voice calls. The messages provide standardized, publicly available information on health insurance eligibility and benefits and reference nearby participating health facilities. SMS messages are personalized by addressing recipients by name. The precise messages are available in the attached pre-analysis plan.

Experimental Design

Experimental Design
The study uses a randomized controlled design in which eligible households are randomly assigned to either a treatment group receiving three rounds of informational messages or a control group receiving no intervention. Randomization is conducted at the household level. Outcomes are measured using survey data collected during the study period and at the end of the study, and impacts are estimated by comparing outcomes between treatment and control households.
