title: Exploring Lab Tests Over Utilization Patterns Using Health Analytics Methods.
abstract: Healthcare resources are over utilized contributing more to the growing costs of care. Although laboratory testing is essential, yet it can be expensive and excessive. King Faisal Specialist Hospital and Research Center, Saudi Arabia studied lab tests utilization patterns using health analytics methods. The objective was to identify patterns of utilizing lab tests and to develop recommendations to control over utilization. Three over utilization patterns were identified; using expensive tests for many patients as routine, unnecessarily repeating lab test and a combined one. Two recommendations were suggested; a user approach, modifying user behavior through orientation about the impact of over utilization on the cost effectiveness of healthcare, and a system approach, implementing system alerts to help physicians check the results and identify the date of the last lab tests done with information about appropriate frequency of ordering such lab test and medically significant intervals at which such test should be repeated.
