Although patient involvement in medication list sharing has the potential to improve information consistency, health systems, providers, and other stakeholders should be cautious in assuming that other prescribers will work to combat medication list entropy, especially if no systems exist to seamlessly incorporate this information into clinic workflow. Devising standardized procedures when patients bring in their records from other providers increases the likelihood that this information will be incorporated into clinical decision making and maintaining up-to-date medication information for patients who use multiple prescribers.
Limitations
These analyses are based on a small sample size (n = 50 for chart review) and (n = 8 for the semistructured interviews) from a single Midwestern state. These findings should be used as evidence for further inquiry.
Conclusion
This study illuminates the level of discrepancies between the medication lists of veteran dual users, including high rates of discrepancies for high-risk medications, such as anticoagulants and opiates. This study also provides evidence of deficiencies in the health care system to decrease medication list entropy that may place veterans at an elevated risk for adverse medication events.
