1. ABSTRACT

The laboratory services play important role in health care provision since it provides clinicians and other health care professional information that will help them to detect disease and to confirm or reject the diagnostics. (McPherson & Matthew R. Pincus, 2011). Managing the follow up of radiological as well as diagnostics test is a complex process since it requires information exchange between different health care practitioners across different services within the health facilities. (Callen, Georgiou, Li, & Westbrook, 2011). Error in the management of laboratory result can carries a risk of harm of patient life and these errors are more present to the pre and post-analytical steps of the total testing process then during the chemical analytical phases inside the laboratory. (Plebani, 2009)

In this study, we havedevelopeda Computerized Provider Order Entry (CPOE) systemto capture and shared laboratory data of the patient across clinical services in the district hospital by the automation of the main pre and post analytical process that are main source of errors. We have focused a particular attention of the modelling of the workflow to identify business process that involve communication between different services and the laboratory. Through the analysis of business process we have identify the main actors and describe the system requirements. A particular attention has been paid to improve patient communication in the proposed workflow.

The system was designed using C# programming language over .Net Framework 4.0 and PostgresSQL to capture patient and laboratory order data from the Out-patient department to patient assignment in clinical services. The result of lab test also has been captured andShort Message Service (SMS) and email notification features have been integrated to send information to both patient and clinician where the lab result was available.
