    AimThe number of nonagenarians undergoing surgery has increased considerably in recent decades as a result of population aging. Greater knowledge of the most influential factors affecting perioperative morbidity and mortality would improve the quality of care and provision of health resources for these patients. The objective of the present study was to analyze the perioperative mortality, and its most determinant factors, among nonagenarian patients who underwent a surgical procedure in the Department of General and Digestive Surgery.MethodsA retrospective descriptive study was carried out in a cohort of 159 consecutive non-selected surgical nonagenarian patients. Clinical data, type of operation, perioperative hemodynamic instability, the need for blood transfusion and medical/surgical complications were evaluated as predictor variables. The outcome variable was operative mortality.ResultsThe mean age was 91.8 years (SD ± 2.0); there were 60 men (37.7%) and 99 (62.3%) women. Perioperative mortality was 28.93% (46 patients). The variables age (P = 0.025), American Society of Anesthesiologists physical status score (P < 0.001), neoplastic pathology (P = 0.025), intestinal surgery (P = 0.001), emergent surgery (P ≤ 0.001), perioperative blood transfusion (P = 0.003), postoperative medical complications (P < 0.001) and surgical complications (P = 0.022) showed a statistically significant correlation with mortality. American Society of Anesthesiologists physical status score (P = 0.007), emergent surgery (P < 0.032) and perioperative blood transfusion (P = 0.047) were identified as independent predictors of mortality.ConclusionsSurgery should not be denied to nonagenarian patients based only on their age. Emergency surgery and American Society of Anesthesiologists physical status classification are the most significant factors when deciding whether to intervene.
