The effect of controlling clinical laboratory errors on patients' safety in Markazi province laboratories

One of the most approaches to coping with medical laboratory errors is the FMEA. The purpose study was to determine the effect of clinical laboratory error on the basis of FMEA on patient safety in laboratories in Markazi province.

The present study was an applied-objective type in terms of quasi-experimental interventional method and for collecting pre-lateral data. The instrument was a standard questionnaire of the WHO patient safety checklist. The statistical population of the study was technical experts of clinical laboratories, which were counted in two groups of intervention and control groups and 71 persons in each group. Data were analyzed by descriptive statistics and Spearman correlation test for correlating variables before, after intervention and Wilcoxon test to determine the effect of clinical laboratory error control on patients' safety.

Using SPSS22 software and according to Spearman, there is a significant correlation between the dimensions of patient's safety before and after intervention (p<0.05). According Wilcoxon test, the effect of clinical laboratory error control on patients' safety and its dimensions, ie, governance and safety of patients (p=0.001, z=6.73), involvement of patients and society (z=-5.83, p=0.001), safe and evidence-based clinical services (p=0.001, z=-6.60) and safe environment (p=0.001, z=-6.109) were approved.

Regarding the effect of controlling laboratory errors on patients' safety, it is suggested that the managers of the laboratories of Markazi province focus on the implementation of the FMEA in order to achieve significant results in long run.
