ABSTRACT Aim To analyse the association between gender and in‐hospital mortality odds ratios among patients in the Basque Country. Design Cross‐sectional study. Methods Admission data pertaining to the period between 1 January 2016 and 31 December 2018 were gathered for all registered acute care hospitals (both public and private) in the Basque Country. Odds ratios were calculated through binomial logistic regressions to determine the association between gender and mortality in each diagnostic category of the ICD‐10. Results Women had a higher in‐hospital mortality odds ratio for diseases of the circulatory system (OR 1.07 [1.01–1.14], p < 0.05). In contrast, men were at greater risk of in‐hospital death from neoplasms (OR 0.86 [0.83–0.94], p < 0.05), diseases of the nervous system (OR 0.83 [0.70–0.97], p < 0.05), diseases of the genitourinary system (OR 0.83 [0.71–0.96], p < 0.05), endocrine diseases (OR 0.67 [0.54–0.84], p < 0.05), injury, poisoning and other consequences of external causes (OR 0.60 [0.54–0.67], p < 0.05) and diseases of the musculoskeletal system and connective tissue (OR 0.69 [0.50–0.93], p < 0.05). Patient or Public Contribution No patient or public contributions.
