Abstract
BACKGROUND: Surgery-related mortality depends on a number of factors including the type of surgical procedure, quality of healthcare, co-morbidities, and age of patient. The objective of the study was to assess the in-hospital mortality in the elderly undergoing surgical treatment. METHODS: This was a national data-based retrospective cohort study. Data were extracted from the National Health Fund, a public organization financing medical procedures in Poland. Adult citizens who underwent 9,344,384 surgical interventions (including 3,093,254 cases in seniors who were above 65 years old) between 2009 and 2012 were included in this study. Overall, surgery type-dependent, age-stratified in-hospital mortality related to surgery was assessed. RESULTS: Overall in-hospital surgery-related mortality rate in seniors was stable (approximately 2 % annually, P for trend = 0.104). It doubled with each successive decade of life (1.2, 2.3, 5.6, and 13 % in 65-74, 75-84, 85-94 and ≥ 95 years old groups, respectively, in 2012). In ≥ 75-year-old mortality exceeded 10 % only after neurological surgeries, in ≥ 85-year-old after neurological, vascular, gastrointestinal, and endocrinological surgeries, and in ≥ 95-year-old also after heart and circulation, bones and muscles, liver, pancreas, and spleen operations. However, even in the oldest individuals it was low after genitourinary, female genital tract, head and neck, and eye surgeries. CONCLUSIONS: The overall rate of in-hospital mortality after surgery, although increasing with age, is rather low up to the ninth decade of life. Whereas some surgeries pose a significant risk, others may be relatively safe even in the oldest subjects.
