Abstract

Background: Hematology analysis comprises some of the highest volume tests run in clinical laboratories. Autoverification of hematology results using computer-based rules reduces turnaround time for many specimens, while strategically targeting specimen review by technologist or pathologist.

Methods: Autoverification rules had been developed over a decade at an 800-bed tertiary/quarternary care academic medical central laboratory serving both adult and pediatric populations. In the process of migrating to newer hematology instruments, we analyzed the rates of the autoverification rules/flags most commonly associated with triggering manual review. We were particularly interested in rules that on their own often led to manual review in the absence of other flags. Prior to the study, autoverification rates were 87.8% (out of 16,073 orders) for complete blood count (CBC) if ordered as a panel and 85.8% (out of 1,940 orders) for CBC components ordered individually (not as the panel).

Results: Detailed analysis of rules/flags that frequently triggered indicated that the immature granulocyte (IG) flag (an instrument parameter) and rules that reflexed platelet by impedance method (PLT-I) to platelet by fluorescent method (PLT-F) represented the two biggest opportunities to increase autoverification. The IG flag threshold had previously been validated at 2%, a setting that resulted in this flag alone preventing autoverification in 6.0% of all samples. The IG flag threshold was raised to 5% after detailed chart review; this was also the instrument vendor's default recommendation for the newer hematology analyzers. Analysis also supported switching to PLT-F for all platelet analysis. Autoverification rates increased to 93.5% (out of 91,692 orders) for CBC as a panel and 89.8% (out of 11,982 orders) for individual components after changes in rules and laboratory practice.

Conclusions: Detailed analysis of autoverification of hematology testing at an academic medical center clinical laboratory that had been using a set of autoverification rules for over a decade revealed opportunities to optimize the parameters. The data analysis was challenging and time-consuming, highlighting opportunities for improvement in software tools that allow for more rapid and routine evaluation of autoverification parameters.

Introduction

In the realm of laboratory information system (LIS) and/or middleware software, autoverification refers to the use of computer-based rules to determine the appropriate release of laboratory test results. With the expansion of data management systems in the lab, autoverification is now a routine practice in core clinical laboratories[1][2][3][4], where the use of well-designed autoverification rules improves both quality and efficiency.[1][2][4] Over the years, autoverification rules have been described in detail for clinical chemistry, blood gas, and coagulation analysis, often achieving autoverification rates of >90%.[5][6][7][8][9][10][11][12]

In contrast, published studies regarding the application of autoverification in hematopathology are more limited.[13][14] Zhao et al. describe the implementation of autoverification rules in hematology analysis in a multicenter setting with 76%–85% autoverification rates.[14] The necessity of manual review of peripheral blood smears precludes achieving the high autoverification rates seen in clinical chemistry. On the other hand, high rates of manual review may place a strain on limited laboratory resources and delay turnaround time without adding clinical value. In 2005, The International Consensus Group for Hematology (ICGH) issued guidelines to establish a uniform set of criteria for manual review of automated hematology testing.[15][16][17][18] The proposed criteria for manual review includes quantitative and qualitative parameters. Pratumvinit et al. optimized the ICGH guidelines to significantly reduce their review rates and increase autoverification.[18] The basic qualitative criteria used for manual review are well-established; however, the specific quantitative cutoffs to trigger manual review are largely set by the individual laboratory, with some recommendations for individual parameters provided by instrument vendors or published literature.[7][15][16][19][20][21] Individual laboratories ideally should optimize their own set of rules to maintain both quality and efficiency within their own context of instrumentation, staffing, and patient population. However, data analysis on specific flags and their clinical impact may be quite challenging to assess.
