Abstract
Appropriate laboratory test utilization is of growing interest in the face of rising healthcare costs and documented evidence of over- and under-utilization. Building from published literature, laboratory organizations have recently published guidelines for establishing laboratory utilization management programs. However, systematic reviews and meta-analyses have consistently struggled to define rigorous evidence-based best practice recommendations due to the paucity of published data or the heterogeneity of available data. We sought to gain information about utilization practices and programs currently in use and which factors contribute to their success by distributing a survey among laboratory professionals. The survey received seventy-four eligible respondents. We observed a wide range in the duration of laboratory utilization programs and the number of stewardship initiatives. In addition, there was great variety in the utilization practices used and the tests or processes targeted by programs. There was similarity in how initiatives are evaluated and who is involved with utilization programs. Finally, respondents often credited a multidisciplinary committee, support from leadership, and strong IT support/data access as important factors for their program's perceived success. Many of these factors agree with previously published literature.
