Compared with other VA high-complexity facilities, DVAHCS was among the top health care systems for total volume of CC prescriptions (n = 16,096) and among the lowest for cost/fill ($75.74). Similarly, DVAHCS was among the top sites for total adjudicated CC PADRs within the 6-month study period (n = 611) and the lowest approval rate (44.2%). This study shows that despite high volumes of overall CC prescriptions and CC PADRs, it is possible to maintain a low overall CC prescription cost/fill compared with other similarly complex sites across the country. Wide variance in reported results exists across high-complexity VA facilities because some sites had low to no CC fills and/or CC PADRs. This is likely a result of administrative differences when handling CC prescriptions and presents an opportunity to standardize this process nationally.
Limitations
CC PADRs were assessed during the COVID-19 pandemic, which might have resulted in lower-than-normal CC prescription and PADR volumes, therefore underestimating the potential for direct cost savings. Entry-level salary was used to demonstrate cost savings potential from the perspective of a newly hired CC team; however, the cost savings might have been less if the actual salaries of site personnel were higher. National contract pricing data were gathered at the time of data collection and might have been different than at the time of PADR submission. Chronic medication prescriptions were annualized, which could overestimate cost savings if the medication was discontinued or changed to an alternative therapy within that time period.
The study’s exclusion criteria could only be applied locally and did not include data received from the VA CC prescription database. This can be seen by the discrepancy in CC PADR approval rates from the local and national data (46.2% vs 44.2%, respectively) and CC PADR volume. High-complexity VA facility data were captured without assessing the CC prescription process at each site. As a result, definitive conclusions cannot be made regarding the impact of a centralized CC pharmacy team compared with other facilities.
Conclusions
Adjudication of CC PADRs by a centralized CC pharmacy team over a 6-month period provided > $500,000 in direct cost savings to a VA health care system. Considering the CC PADR approval rate seen in this study, the VA could allocate resources to educate CC providers about the VA formulary to increase the PADR approval rate and reduce administrative burden for VA pharmacies and prescribers. Future research should evaluate CC prescription handling practices at other VA facilities to compare the effectiveness among varying approaches and develop recommendations for a nationally standardized process.
