[Mortality from chronic kidney disease in Peru: national trends 2003-2015].

OBJECTIVES.: To describe the mortality trend due to chronic kidney disease (CKD) in Peru in the period 2003-2015. MATERIALS AND METHODS.: Analysis of secondary data and ecological design. National mortality registries based on death certificates were analyzed. ERC was defined as CIE code 10: N18 in the basic cause. Absolute and relative frequencies of death by ERC are described. To estimate the proportion of deaths by CKD in each region of Peru, a generalized mixed linear model was used. The outcome variable was the proportion of deaths, the independent variables were each region of the country and the year. RESULTS.: The analysis included 1,086,778 deaths, of which 25,091 (2.0 % age- and sex-adjusted) were by CKD. During the study period, the average age at death increased by 2.6 years (p<0.001); in addition, the proportion of age- and sex-adjusted CKD deaths was always higher in women. In the observation period, the region with the highest mortality from CKD was Puno (4.1%), and with the lowest mortality was Amazonas (1.1%). Those regions that showed a significantly greater increase than the others were Tacna, La Libertad, Tumbes, Apurímac, Cusco, Ica, Moquegua, Ayacucho, Huancavelica and Puno. CONCLUSIONS.: In the 2003-2015 period, mortality from CKD in Peru has increased; this trend is observed in several regions of the country. Preventive measures, early identification, and access to treatment must be implemented to control this trend.
