Gross Dissection Time Values of Pathologists' Assistants Using Standardized Metrics

Area of Science:

• Pathology
• Medical Laboratory Science
• Healthcare Management

Background:

• Objective quantification of pathologists' assistants (PAs) gross dissection time is lacking.
• Existing systems do not provide standardized metrics for PA productivity.
• Need for a reliable method to assess and monitor PA work effort in grossing specimens.

Purpose of the Study:

• To develop and validate a method for calculating standardized work units (dissection time values [DTVs]).
• To establish an objective measure for monitoring the gross dissection time of pathologists' assistants.
• To improve the assessment of PA productivity and efficiency.

Main Methods:

• Classified 176 specimen types into five complexity levels based on expected dissection time.
• Collected prospective dissection time data for 12,775 specimens across two academic medical centers.
• Calculated DTVs by converting measured dissection time into a standardized work unit.

Main Results:

• Developed a numeric standard for work effort for 155 specimen types.
• Validated the method by comparing expected vs. actual dissection times.
• Identified 44 specimen types requiring reclassification to lower complexity levels due to shorter-than-expected dissection times.

Conclusions:

• A validated, objective method to quantify gross dissection time for PAs was successfully developed.
• The established DTVs provide a reliable tool for monitoring PA productivity and grossing efficiency.
• The method allows for continuous assessment and optimization of PA performance in pathology.
