Incidencia y tipo de efectos adversos durante el procedimiento de hemodiálisis

Abstract

Introduction
Nowadays patient safety is a priority for the main health organizations such as the World Health Organization, international bodies such as the European Union, the Council of Europe, healthcare authorities, professional associations and patient organizations.
Objective
To describe the incidence and types of adverse effects deriving from haemodialysis in a nephrology unit.
Methodology
Design: Transversal study in 28-bed haemodialysis unit. Variables: as a dependent variable, the present of adverse effects and typology was considered, using the International Classifi cation for Patient Safety. Statistical analyses: a description of the sample was carried out, using graphs (histograms, bar diagrams, and dispersion diagrams) and also percentages, means, standard deviations, medians, etc.
Results
During the period studied a total of 4797 haemodialysis procedures were carried out, with adverse effects arising in a total of 681 sessions, which represents an incidence rate of 141.96 per 1000 dialyses. As far as severity is concerned, 97.5% of the adverse effects were classifi ed as mild, compared to 1.8% and 0.7% which were considered moderate and serious, respectively. Conclusions
Our incidence rate and severity of adverse effects is similar to other centres. This study lets us identify safety problems in our Unit and in a second phase establish a joint protocol which will allow us to reduce the current incident rate. Hypotension was the most common adverse effect.
