Patient-reported outcomes and pharmacist actions in patients with multiple sclerosis managed by health-system specialty pharmacies.

PURPOSE: This study evaluated patient-reported outcomes (PROs) and pharmacist actions for patients on disease-modifying therapies (DMTs) for multiple sclerosis (MS) through health-system specialty pharmacies (HSSPs). METHODS: A multisite, prospective cohort study of patients utilizing an HSSP for DMT fulfillment was performed. Primary outcomes were affirmative answers to PRO questions regarding impacted productivity, hospitalization, and relapse and pharmacist actions. Rates of pharmacist actions were reported as the number of person-years of treatment per action. Univariate and multivariate logistic regression were used to evaluate the association between each PRO and covariates, including the number of pharmacist actions performed, age, sex, insurance, site, and route of administration. RESULTS: The 968 patients included had 10,562 fills and 6,946 PRO assessments. The most common affirmative PRO was impacted productivity (14.6%). Pharmacists performed 3,683 actions, most commonly general medication education (42.6%) and safety (33.3%). Rates of general medication education and nonfinancial coordination of care actions were similar across medication classes; other pharmacist actions varied by medication class. Insurance type was significantly associated with reporting impacted productivity; patients with Medicare and Medicaid were 2.2 and 3.1 times more likely to have reported impacted productivity, respectively (P < 0.001) than commercially insured patients. Patients who reported impacted productivity had more pharmacist actions (P < 0.001). CONCLUSION: Patients on DMTs through an HSSP reported low rates of impacted productivity, relapse, and hospitalization due to MS, although patients with noncommercial insurance were more likely to have impacted productivity. Patients reporting impacted productivity and those taking certain DMTs may require more frequent pharmacist actions.

Adherence and persistence to self-administered disease-modifying therapies in patients with multiple sclerosis: A multisite analysis.

BACKGROUND: Though there are several disease-modifying therapy (DMT) options for patients with multiple sclerosis (MS), treatment outcomes rely on patient adherence and persistence. Previous studies have demonstrated suboptimal adherence rates and high rates of early treatment discontinuation. Health-system specialty pharmacies (HSPPs) are a growing practice model that have demonstrated adherence and persistence benefits through single site evaluations. Research is needed across multiple HSSPs to understand and validate the outcomes of this practice model. METHODS: A multisite prospective cohort study was performed including patients with at least three fills of a DMT between January 2020 and June 2021 at an HSSP. Patients were excluded due to pregnancy or death. Enrollment occurred for 6 months followed by 12 months of follow-up. Adherence was measured using pharmacy claims to calculate proportion of days covered (PDC) during the follow-up period. Time to non-persistence was calculated as the time from an index DMT fill to the first date of a gap of >60 days between medication exhaust and fulfillment dates. Adherence and persistence calculations were assessed at the therapeutic class level (any self-administered DMT dispensed by the HSSPs). The Kaplan-Meier method was used to present the probability of being persistent, and Cox proportional hazards regression analysis was used to estimate hazard ratios of factors associated with non-persistence, which included age, sex, study site, insurance type, and whether the patient switched medication as potential factors. RESULTS: The most common self-administered DMTs filled among 968 patients were glatiramer acetate (32%), fingolimod (18%), and dimethyl fumarate (18%). Most patients (96%) did not switch DMT during the study period. The median PDC was 0.97 (interquartile range 0.90-0.99), which was similar across all sites. Patients who had at least one DMT switch were 76% less likely to have a higher PDC than those who did not have any switch after adjusting for other covariates (Odds ratio: 0.24, 95% confidence interval [CI]: 0.14-0.40, p<0.001). Most patients (86%) were persistent to DMT over the 12-month study period. Among those non-persistent, median time to non-persistence was 231 (IQR 177-301) days. Patients who switched medications were 2.4 times more likely to be non-persistent (95% CI: 1.3 - 4.5, p = 0.005). The most common reasons for non-persistence were discontinuation/medication held for an extended period (30%), often due to patient or prescriber decision (75%). CONCLUSION: High rates of DMT adherence and persistence were seen among patients serviced by HSSPs, indicating potential benefits of this model for patients with MS. Switching DMTs was associated with lower adherence and persistence and may be an opportunity for added care coordination or resources to optimize therapy transitions.

Pneumococcal Vaccination Practices in Patients With Multiple Sclerosis Receiving Anti-CD20 Monoclonal Antibodies After Pharmacy and Nursing Collaboration.

BACKGROUND: It is recommended that patients taking immunosuppressive anti-CD20 monoclonal antibodies (mAbs) receive pneumococcal vaccinations before their first dose to ensure optimal immune response. An initial medication use evaluation reviewed adherence to Centers for Disease Control and Prevention (CDC) pneumococcal immunization recommendations at the study site, and room for improvement was identified. The nursing team implemented workflow changes to increase nursing involvement in vaccination coordination, education, tracking, and administration. We sought to evaluate the impact of a nursing intervention on optimal pneumococcal vaccination administration rates in patients receiving anti-CD20 mAbs at a multiple sclerosis (MS) center. METHODS: We performed a single-center, retrospective, pre/post medication use evaluation. Inclusion criteria were older than 18 years with a diagnosis of MS and received their first anti-CD20 mAb infusion at the study site during the preintervention or postintervention time frame. RESULTS: We included 406 and 73 patients in the preintervention and postintervention studies, respectively. The nursing intervention significantly improved the percentage of patients receiving optimal pneumococcal vaccination before their first infusion from 58% to 84% and significantly reduced the number with unknown vaccination status from 17% to 3%. Patients who received optimal follow-up vaccination with 23-valent pneumococcal polysaccharide vaccine after optimal 13-valent pneumococcal conjugate vaccine administration improved from 9% to 56%. CONCLUSIONS: A nursing team intervention improved adherence to CDC pneumococcal immunization recommendations for patients receiving anti-CD20 mAb therapy. This project highlights the value of interdisciplinary team collaboration between health system specialty pharmacies and specialized nursing teams in the care of patients with MS.
