Abstract
Background: The laboratory testing process consists of five analysis phases, featuring the total testing process (TTP) framework. Activities in laboratory processing, including those of testing, are error-prone and affect the use of laboratory information systems (LIS). This study seeks to identify error factors related to system use, as well as the first and last phases of the laboratory testing process, using a proposed framework known as the "total testing process for laboratory information systems" (TTP-LIS).
Methods: We conducted a qualitative case study evaluation in two private hospitals and a medical laboratory. We collected data using interviews, observations, and document analysis methods involving physicians, nurses, an information technology officer, and the laboratory staff. We employed the proposed framework and lean problem solving tools, namely value-stream mapping and the A3 process for data analysis.
Results: Errors in an LIS and the laboratory testing process were attributed to failure to fulfill user requirements, poor cooperation between the information technology unit and laboratory, inconsistency of software design in system integration, errors during inter-system data transmission, and lack of motivation in system use. The error factors are related to system development elements, namely latent failures that considerably affected information quality and system use. Errors in system development were also attributed to poor service quality.
Conclusions: Complex laboratory testing processes and LISs require rigorous evaluation in minimizing errors and ensuring patient safety. The proposed framework and lean approach are applicable for evaluating the laboratory testing process and LISs in a rigorous, comprehensive, and structured manner.
