Use of value stream mapping to improve the medication synchronization process

Abstract

Background: Lean methodology, specifically value stream mapping, can be used to identify and reduce inefficiencies in the medication synchronization process.

Objectives: The objectives of this study were to (1) evaluate potential medication synchronization process improvements to reduce nonvalue-added actions, (2) assess fidelity to the medication synchronization core components, and (3) identify the best process for medication synchronization for an independent community pharmacy with multiple locations.

Methods: This study used an observational, cross-sectional design. A value stream map was created to provide a detailed illustration of each step in the medication synchronization process. Time for each step of the medication synchronization process was observed on site on different days and times as well as the time required to process, package, and verify prescription medications. These steps were conducted before interventions were made to the process and after to compare the difference. The organizational readiness for change tool was administered to employees of the independent pharmacy before interventions to determine their perspective of the medication synchronization process and assess their readiness for change.

Results: Owing to various interventions made to the medication synchronization process, 2 steps in the process were eliminated. This resulted in a decrease in adherence packaging time workflow by 69.4%. Staff (n = 9) rated the medication synchronization process on 4 components: acceptability of the current process (13.8 ± 3.6), intervention appropriateness (13.7 ± 3.7), feasibility of a new medication synchronization process (17.1 ± 2.3), and organizational level of support (21.8 ± 4.1).

Conclusion: Value stream mapping proved to be a valuable tool in identifying inefficiencies in the medication synchronization process and reducing nonvalue-added waste. The result was a decrease in time required for adherence packaging workflow and a more standardized medication synchronization process across multiple independent pharmacy locations. This more standardized process can play a key role in improving the continuity of patient care, increasing medication adherence, and in turn decreasing the number of hospital admissions.
