Improving Adherence and Reducing Health Care Costs Through Blister-Packaging: An Economic Model for a Commercially Insured Health Plan.

Purpose: To model the potential clinical and economic impact of blister-packaging medications for chronic conditions on medication adherence and healthcare costs in a commercially insured population. Methods: A health economic model was developed to evaluate the potential impact of blister-packaging chronic medications for a commercially insured population. The chronic medication classes assessed were renin-angiotensin-system (RAS) antagonists, statins, non-insulin oral antidiabetics, and direct oral anticoagulants (DOACs). The model was designed to reflect the perspective of a hypothetical commercially insured health plan with 100,000 members, over a one-year time horizon. Literature-based or best available epidemiologic references were used to inform the number of patients utilizing each medication class, the impact of blister-packaging on the number of patients who become adherent, as well as the impact of medication adherence in a commercially insured population on healthcare costs for each medication class assessed. Impact on costs was measured in total net healthcare costs, as well as being stratified by medical costs and medication costs. Results: Following the blister-packaging intervention, there were an additional 591 patients adherent to RAS antagonists, 1196 patients adherent to statins, 169 patients adherent to oral antidiabetics, and 25 patients adherent to DOACs. While pharmacy costs increased, these costs were more than offset by the reduction in medical costs. Overall, the increase in patients adherent to therapy due to blister-packaging led to a reduction in total healthcare costs of $879,312 for RAS antagonists (-$0.73 per-member per-month (PMPM)), $343,322 for statins (-$0.29 PMPM), $78,917 for oral antidiabetics (-$0.07 PMPM), and $120,793 for DOACs (-$0.10 PMPM). Conclusion: Blister-packaging chronic medications in a commercially insured population has the potential to reduce healthcare costs. Future research is needed to confirm these findings in real-world settings and to fully understand the clinical and economic implications of blister-packaging chronic medications.

Patients not taking their medications as prescribed is common in the United States, leading to disease progression, increased healthcare visits, and increased healthcare costs. Blister-packaging medications is an intervention shown to increase medication adherence, or patients taking their medication as prescribed, and has been around for several decades. While there is research and literature available that shows the impact that blister-packaging medications has on improving adherence, and there is literature available that shows patients taking their medications as prescribed reduces healthcare costs, there is minimal literature available that directly ties these two concepts together. As a result, we modeled from a hypothetical commercial insurance health plan perspective what the impact would be of blister-packaging chronic medications on healthcare costs using the best available peer-reviewed literature and epidemiologic data. This analysis found that for a commercially insured health plan with 100,000 members, 591 additional patients would become adherent to their renin-angiotensin-system (RAS) antagonists blood pressure medications, 1196 additional patients would become adherent to their statins, 169 additional patients would become adherent to their oral antidiabetics, and 25 additional patients would become adherent to their direct oral anticoagulants (DOACs). Additionally, this would lead to a reduction in healthcare costs for the health plan of $879,312 for RAS antagonists (-$0.73 per-member per-month (PMPM)), $343,322 for statins (-$0.29 PMPM), $78,917 for oral antidiabetics (-$0.07 PMPM), and $120,793 for DOACs (-$0.10 PMPM).

Estimating the economic impact of blister-packaging on medication adherence and health care costs for a Medicare Advantage health plan.

BACKGROUND: Medication nonadherence is a persistent challenge in the United States, leading to increased health care resource utilization (HCRU) and health care costs and worsened health outcomes. Medicare Star Ratings is a program developed by the Centers for Medicare and Medicaid Services (CMS) to evaluate Medicare health plan quality and performance. Three of the Medicare Part D Star Ratings quality measures assess medication adherence, showing the importance CMS places on improving medication adherence in older adults. Although a variety of medication adherence-enhancing interventions are available to help promote adherence among patients, one intervention that has shown success historically is blister-packaging. OBJECTIVE: To model the potential impact of blister-packaging chronic medications on HCRU and health care costs in the Medicare population. METHODS: An economic model was developed to assess the potential impact of blister-packaging the 3 Medicare Star Ratings adherence measure medication classes: renin-angiotensin system antagonists (RASAs), statins, and noninsulin antidiabetics. The model perspective was that of a hypothetical Medicare Advantage health plan with a plan size of 100,000 members. A 12-month time horizon was used in the model. The dichotomous adherence threshold in the model was set at 80% or greater of the proportion of days covered (PDC). Literature-based references were used to inform both the impact of blister-packaging on the number of patients who become adherent as well as the impact of medication adherence on HCRU and health care costs for each of the medication classes. One-way sensitivity analyses and several scenario analyses were conducted to assess model uncertainty. RESULTS: Owing to increased adherence from the blister-packaging intervention, the hypothetical health plan in the analysis saw 776 additional members adherent to RASAs, 1,651 additional members adherent to statins, and 414 additional members adherent to oral antidiabetics. Although medication expenditure increased for all 3 medication classes (RASAs: $274,963; statins: $730,083; oral antidiabetics: $100,529), medical costs decreased across all classes (RASAs: -$4,098,848; statins: -$5,549,699; oral antidiabetics: -$917,968). Total net health care costs decreased by $3,823,885 for RASAs (-$3.19 per member per month [PMPM]), $4,819,616 for statins (-$4.02 PMPM), and $817,438 for oral antidiabetics (-$0.68 PMPM). The entire Medicare Advantage population scenario analysis saw reductions in total health care costs of $1,081,394,737 for RASAs, $1,362,987,376 for statins, and $231,171,496 for oral antidiabetics. CONCLUSIONS: Dispensing chronic medications with blister-packaging for Medicare Advantage health plan patients was modeled to reduce HCRU and health care costs. Future studies are needed to assess whether the impact of blister-packaging medications is tied to reductions in HCRU and health care costs in real-world settings.

Evaluation of telepharmacy and the use of a gravimetric technology-assisted workflow system for remote sterile product pharmacist checks.

PURPOSE: To evaluate the impact of remote sterile product pharmacist checks when used with a gravimetric-based technology-assisted workflow (TAWF) system on product checking accuracy, pharmacist review time, workload sharing, cost savings, and staff perceptions. METHODS: A double-arm, prospective study was conducted at 4 pharmacy locations for a 90-day period. Each compounded sterile product (CSP) checked by a remote pharmacist was also checked by a local pharmacist at the site of CSP preparation. An anonymous, online survey was emailed to staff before and after implementation to evaluate perceptions of the accuracy, timeliness, safety, potential impact, and value of the remote process. RESULTS: There was no statistically significant difference in the numbers of errors detected through the remote process and through the current, nonremote process (P = 0.177). The median pharmacist review time in the local process was significantly lower (P < 0.001). Remote pharmacists in the study workflow verified 30.4% of the total number of CSPs verified in the 90-day period. Annualized cost savings were calculated to be $23,770.08. Percent agreement increased from the preimplementation to the postimplementation period for survey questions about the safety of the remote process, opportunity for workload sharing, and optimization of current workflow. Percent agreement decreased for questions about the accuracy, timeliness, and value of the remote process and its impact on job security. CONCLUSION: The study demonstrated that with use of a gravimetric-based TAWF system, there was no difference in the accuracy and safety of sterile product pharmacist checks performed remotely and those performed at the product preparation site. In addition, the remote process allows for opportunities for workload sharing and cost savings.

Evaluation of a gravimetric-based technology-assisted workflow system on hazardous sterile product preparation.

PURPOSE: The impact of a gravimetric-based technology-assisted workflow (TAWF) system on hazardous compounded sterile product (CSP) production time, staff perception of safety, and job satisfaction was evaluated. METHODS: For 2 weeks before implementation of a gravimetric-based TAWF, staff utilized an automated punch clock to document the time to prepare and check CSPs compounded volumetrically. Simultaneously, an anonymous, online survey was e-mailed to staff to evaluate their perceptions regarding the safety of volumetric preparation and satisfaction with their role preparing CSPs. At 30 and 90 days postimplementation of the TAWF, staff completed identical follow-up surveys to evaluate safety and satisfaction using the gravimetric-based TAWF. The TAWF software captured product preparation and check times postimplementation. Data regarding the accuracy of compounding were collected postimplementation and compared to accuracy data available in the published literature. RESULTS: The median time to prepare CSPs preimplementation (n = 643) was 445 seconds versus 359 seconds (n = 728) 90 days after implementation of the gravimetric-based TAWF (p < 0.001). The median time to review and check CSPs was 45 seconds before implementation and 19 seconds 90 days after implementation (p < 0.01). Survey respondents preferred to use the TAWF to compound CSPs over volumetric preparation. There was no difference in respondents' perception of safety and accuracy of the TAWF preimplementation versus postimplementation. CONCLUSION: The gravimetric-based TAWF preparation of hazardous CSPs was faster and more accurate than manual volumetric preparation and improved staff perception regarding the accuracy of the CSP preparation process.
