ABSTRACT
Introduction: Peritonitis reaches an overall mortality up to 60%. Given the lack of national epidemiological studies, it is proposed the calculation of the mortality rate (MR) due to peritonitis between the years 2017-2021 in Chile. Methodology: Descriptive, ecological study about deaths by peritonitis between 2017 and 2021 in Chile (N=1,741), in a population older than 15 years old according to age group, sex and region with data obtained from Departamento de Estadística e Información en Salud. Descriptive statistics were used, MR calculation and Swaroop Index (SI). It did not require approval by an ethics committee. Results: A MR of 2.47/100.000 was calculated between the years 2017 and 2021, with 2020 being the highest with 3.07. The female sex presented a rate of 2.65. The age group with the highest MR is 80 and over with 141.7/100.000. For the SI by region, the XV and XII regions lead with 100%, the lowest being XI region with 83.3%. Discussion:: The peak of MR for the year 2020 coincides with the Covid-19 pandemic and the highest postoperative mortality on infected patients. The SI remains above 90% in the country, except in X and XI regions, probably due to the lower availability of high complexity centers. Conclusion: Given the lack of recent mortality data for peritonitis, a local epidemiological update was carried out, with a regional comparative perspective regarding MR in the general population and in those over 50 years old.
