Assessment of Consolidated Mail Outpatient Pharmacy Utilization in the Indian Health Service

Abstract

The Indian Health Service (IHS) has an agreement with the US Department of Veterans Affairs (VA) that allows IHS to use the VA Consolidated Mail Outpatient Pharmacy (CMOP) to send prescriptions to IHS patients. However, there is high variability among IHS facilities in the use of CMOP. Furthermore, there is no available resource that summarizes the relative positives/negatives, challenges/opportunities, and strengths/weaknesses of implementing CMOP. A 10-item questionnaire was developed to collect information on various aspects of prescription processing through CMOP. The questionnaire was distributed among the primary CMOP contacts of IHS facilities between December 2018 and January 2019. The CMOP contacts at 44 of 94 (47%) IHS sites responded to the survey. Of the 347 respondents, 310 (89%) pharmacists were trained in CMOP prescription processing. To get information about CMOP rejections, 53% (185/347) of pharmacists check electronic messages. Twelve (27%) sites utilize technicians in some capacity in the CMOP process. Of the 16 facilities that require patients to request prescriptions to be mailed for each refill request, 8 (50%) do not use any method to designate a CMOP patient. Three sites (7%) have measured patient satisfaction with the CMOP program. Thirteen sites (31%) reported that they are losing insurance reimbursements by using CMOP. The decrease in insurance reimbursements, lengthy prescription processing time, and medication backorders are the most common challenges shared by respondents. CMOP presents unique challenges to pharmacy workflow but provides many benefits that local pharmacy mailout programs usually do not possess, such as the ability to mail refrigerated items. Furthermore, it is likely that local programs that utilize mail delivery will increase pharmacy workload. However, there is a lack of objective data to assess the net effect of CMOP on patients. Nevertheless, the successful implementation of CMOP can lead to reduced pharmacy workload while increasing access to care for patients with transportation issues.
