BackgroundComplications following major abdominal surgery are common and an important cause of morbidity and mortality. The aim of this study was to describe 1-year mortality and identify factors that influence adverse outcomes after abdominal surgery.MethodsThis prospective observational cohort study was performed in Landspitali University Hospital and included all adult patients undergoing abdominal surgery requiring > 24-h hospital admission over 13 months. The follow-up period was 60 days for complications and 24 months for mortality.ResultsData were available for 1113 (99.5%) of the 1119 patients who fulfilled inclusion criteria. A total of 23% of patients had at least one underlying co-morbidity. Non-elective surgeries were 48% and 13% of the patients were admitted to ICU post-operatively. A total of 20% of patients developed complications. Mortality at 30 days, 1 and 2 years was 1.8%, 5.6%, and 8.3% respectively. One-year mortality for those admitted to ICU was 18%. The long-term survival of the individuals surviving 30 days was significantly worse than for an age- and gender-matched population control group. Independent predictors for 1-year mortality were age, pre-operative acute kidney injury and intermediate- or major surgery.ConclusionPost-operative complication rates and mortality following abdominal surgery in Iceland were comparable or in the lower range of previously published outcomes, validating the utility of offering a full host of abdominal surgical services in geographically isolated region with a relatively small referral base.© 2017 The Acta Anaesthesiologica Scandinavica Foundation.
