The National Audit of Hospital Mortality (NAHM) monitors the outcomes of patients admitted for treatment in 44 acute hospitals in Ireland. NAHM uses a web-based tool called NQAIS NAHM to calculate a standardised mortality ratio (SMR). The data used are from information routinely collected from patients in hospitals, managed by the Healthcare Pricing Office, and sent to the HSE to be applied to NQAIS NAHM. Each hospital can examine its mortality patterns and learn from them. The hospitals have an ongoing view of their data for all the different diagnoses patients may present with. Hospitals can compare data to the national average for a condition and produce reports for presentation to hospital management.
