Compliance-Aware Payment Gateway Operations for Healthcare and Medical Device Ecosystems: A DevOps Framework for Resilient Digital Transaction Systems

Healthcare and medical device ecosystems increasingly depend on reliable digital transaction sys-tems for patient payments, provider collections, device-service billing, repair fees, warranty adjustments, refunds, reversals, chargeback evidence, settlement, and reconciliation. In such environments, payment gateway failures are not only technical incidents but also business, operational, and compliance risks. This paper proposes a compliance-aware DevOps framework for resilient digital transaction systems in healthcare and medical device ecosystems. The framework integrates payment gateway operations, transaction lifecycle monitoring, DevOps observability, incident response automation, business-impact scoring, and compliance evidence mapping. A simulation-based evaluation is designed using the PaySim synthetic financial transaction dataset as the base transaction layer. Synthetic healthcare workflow labels, payment gateway operational attributes, DevOps telemetry, and compliance evidence fields are gener-ated through controlled and reproducible rules. Six failure scenarios are injected: authorization timeout, refund failure, reversal delay, settlement mismatch, gateway latency spike, and deployment-induced transaction failure. The proposed framework is compared with two baselines: generic infrastructure monitoring and payment-only monitoring. Across repeated simulation runs, the proposed framework reduces mean time to detect and mean time to recover while improving reversal completion, refund completion, reconciliation handling, and compliance evidence completeness. The study contributes a reproducible business-DevOps model for mapping payment lifecycle exceptions to observability signals, recovery runbooks, business-impact scores, and compliance evidence controls in regulated transaction environments.
