Comparison of previous reports in indoor patients-a potential tool for internal quality assurance in clinical biochemistry

Parveen Bansal


Laboratory testing is an important and integral part of the decision-making process and strongly influences medical diagnosis and therapies. Normally the extraneous results in a clinical report raise a doubt towards the quality assurance program of a laboratory. This communication is intended to highlight the potential use of previous reports of indoor patient in an indoor hospital laboratory as a tool for quality assurance. In this study approximately 10% of the doubtful reports were picked up randomly and the results were compared with the earlier reports of the patient retrieved from database. The study revealed that there was a significant reduction of more than 80% in the test repeats resulting in decrease in expenses on repeat tests (80%).There was a significant average reduction of time and human resource investment, decrease in the instrument working hours and increased workflow efficiency due to reduction in the test repeats. Moreover there was an increase in the confidence level of consultant towards quality control program and authenticity of the reports.
