Biometric Monitoring, Service Delivery, and Misreporting: Evidence from Healthcare in India
研究印度贫民窟结核病治疗中心安装生物识别监控设备的效果，发现设备使患者中断治疗概率降低25%，并改善了数据质量。
Abstract We examine the impact of biometric monitoring devices placed in tuberculosis treatment centers in Indian slums. The devices record health worker attendance and patient visits. Combining survey data, random center visits, and hospital registers, we find that patients at biometric-equipped centers are 25% less likely to interrupt treatment, reflecting increased efforts by health workers and greater daily adherence by patients. The technology also improves the quality of public data by reducing overreported patient numbers and underreported treatment interruptions. Overall, our results suggest that real-time monitoring of service delivery can strengthen the state’s capacity to serve poor and marginalized populations.
