Background: A retrospective study of 138 patients with fractured hips was undertaken to determine if a delay to surgery beyond 24 h influenced 1‐year mortality. In particular, the results of the subgroup of patients who were in the American Society of Anesthesiologists (ASA) Class 3 or 4 were considered. Methods: Patients were found using ICD‐9 database information. One‐year mortality data was collected from Births, Deaths and Marriages − the New Zealand government agency that collects and stores statistics on these events. Results: The 1‐year mortality rate was 17.4%. Age, operation type and time to surgery did not significantly affect 1‐year mortality. American Society of Anesthesiologists’ Class 1 and 2 patients had a significantly lower 1‐year mortality (5.3%) than ASA Class 3 and 4 patients (22.4%) ( P = 0.02). Conclusion: Time to surgery did not significantly affect 1‐year mortality within each ASA Class.
