Background: Although comprehensive medication review (CMR) services have been shown to provide value to patients and payers, the extent of uniformity in service delivery is unknown. A variety of standards and recommendations are available from academic and professional sources, but variation in service provision is an important consideration when attempting to measure or compare service quality nationally.
Objective: This study aimed to identify and summarize trends in the peer-reviewed and gray literature describing telephonic CMR delivery and content.
Methods: A scoping review of peer-reviewed and gray literature was conducted to quantify and qualify trends in CMR service. Two independent reviewers screened abstracts from 9 bibliographic databases and selected gray literature sources in accordance with the Joanna Briggs Institute guidelines and an internally developed protocol. Inclusion criteria for the review were English language; discussion of telephonic CMR service in the United States; research, legislation, or guidelines that describe CMR content coverage requirements for payment; and publication from the year 2000 to the present. Data relating to publication type, study design, setting, region, and themes of CMR content were collated into a Microsoft Excel data extraction form. Qualitative thematic analysis was conducted, and key findings and concepts were reported contextually.
Results: Of 374 identified documents screened, 15 were included in this scoping review and thematic analysis. The following characteristics of CMRs were identified: content, coverage, eligibility, frequency, process, and responsiveness. All published documents (n = 15, 100%) included a discussion of CMR content, and 14 sources (93%) addressed process elements of providing a CMR. Discussion of other themes varied in frequency across documents, ranging from 3 articles (20%) addressing organizational goals for CMR to 12 articles (80%) including elements of responsiveness. Within-theme variation was also observed for several CMR content areas. CMR process was the most heterogeneous theme with topics ranging from access to patient health records to pharmacist training.
Conclusions: Assessment of telephonic CMR comprised a small but steadily increasing portion of the medication therapy management literature. Publications since 2015 have shown an increasing consensus of CMR content and purpose. Per the identified literature, there is an ongoing demand for higher-quality, more holistic CMRs, but there is no consensus on how to measure CMR quality. Future work should include engaging with CMR experts to understand variability in measures of CMR success.
