Improving Laboratory Result Retrieval Times Within the Home Health Setting

Abstract

This quality improvement project focuses on decreasing laboratory result retrieval times within a 6-month period at a rural home health setting. Prior to implementation, 73% of all laboratory results were not received within 24 hours (72 hours for cultures). Interventions included Lean Six Sigma methodologies (process mapping and process redesign) and Plan-Do-Study-Act to reduce laboratory result retrieval times. Data analysis included descriptive statistics including means, averages, and percentages for the primary outcome of laboratory result retrieval time. 119 participants included all patients who had laboratory specimens collected by home health staff during the project timeline. Laboratory result delays ≥24/72 hours decreased from 73% (29/40) to 14% (11/79). Furthermore, 25% (10/40) of labs were delayed ≥5 days pre-implementation and 0% post-implementation. Abnormal laboratory results with delayed treatment decreased from 28% (11/40) to 5% (4/79). Provider notification within 24 hours of an abnormal laboratory result increased from 0% (0/13) to 75% (6/8). Hospitalization rates within 30 days of an abnormal result was 15% (6/40) pre-implementation and decreased to 5% (4/79) post-implementation.
