Abstract
Background: In the current healthcare industry, laboratory services have been cited as one of the key processes promoting safe patient care. The diagnostic decision-making process, however, is hampered by errors that occur in the overall testing processes. This study's goal was to evaluate testing errors across the board in the Clinical Bio-Chemistry Laboratory of the Tertiary Care Hospital Laboratory, Chengalpattu.
Methodlogy: A cross-sectional investigation was carried out in the laboratory of a tertiary care hospital, Chengalpattu. Known quality indicators were used to gather all the necessary data. In order to evaluate the data, SPSS version for windows 26 was used. The descriptive data and chi-square were presented using frequencies and cross-tabulations.
Results: 206 samples in total, along with associated lab request forms, were received for examination. Pre-analytical errors made up 4.40 percent of the total errors, and post-analytical errors made up 2.64 percent, according to the examination of the overall distribution of errors. The most frequent pre-analytical errors were incomplete request form filling, followed by patient location and clinical detail. The primary flaw in the post-analytical step of quality assurance is excessive turnaround time.
Conclusion: The current research revealed a comparatively high frequency of errors, raising concerns about the necessity of using quality indicators to gauge errors throughout the entire testing process. Utilizing laboratory standards, hospital laboratory should evaluate the error and implement the necessary corrective action.
