title: Optimization of utilization of serum protein analysis: role of the electronic medical record in promoting consultation by pathology.
abstract: Screening for monoclonal gammopathies is usually done by serum protein electrophoresis (SPEP) and serum free light chain tests. SPEP may be followed by immunofixation electrophoresis (IFE). IFE may be ordered by the treating physician or be at the discretion of the pathologist. We examined the appropriateness of IFE ordering by treating physicians and report on our findings, follow-up changes to the ordering process, and results of the change. We retrospectively analyzed the data from our laboratory from April 2009 through July 2012. In April 2009, 3 options for test ordering were available for the clinicians: SPEP with reflex IFE, SPEP only, and SPEP with IFE. This test ordering option was limited to SPEP with reflex IFE only in April 2010. We compared the rates of SPEP and IFE performed in the 2 periods (ie, April 2009 through April 2010 and May 2010 through July 2012). There was a substantial drop in the IFE/SPEP ratio from 0.47 to 0.21. Review of electronic medical records by the consultant pathologist was instrumental in improving the utilization and enhancing the value of pathology consultation. Possible impacts on laboratory costs, revenue, and overall health care are also presented.
