VOWR: Vital Operational Waiting Risk for Healthcare Systems

Vital Operational Waiting Risk (VOWR) provides tools for analysing monthly Referral-to-Treatment (RTT) panel data in healthcare systems. The package supports provider-level profiling, operational risk classification, waiting-time volatility assessment, Kaplan-Meier survival analysis, Cox proportional hazards modelling, and visualisation of time-to-threshold breach patterns. It is designed to help analysts and decision-makers identify providers with high waiting times, unstable performance, and increased risk of earlier threshold breach. The survival modelling methods follow Cox (1972) <doi:10.1111/j.2517-6161.1972.tb00899.x> and Kaplan and Meier (1958) <doi:10.1080/01621459.1958.10501452>.
