Infection incidence and management in multiple sclerosis patients after initiating disease-modifying therapy.

Disease-modifying therapies for multiple sclerosis (MS) are effective, but frequently cost $70,000+/year and can predispose patients to serious infections. This retrospective cohort analysis (N = 3,204) compared rates of infections over a 24-month period by MS medication route of administration and antimicrobial use. Infection rates were: 38.7% (oral), 37.3% (infused), and 36.8% (injectable). Of those infections, antimicrobials were prescribed in 86.5% (oral), 84.3% (infused), and 85.5% (injectable) cases. We found differences within bacterial and herpes zoster infection rates (and antimicrobial use) among new users by medication route of administration. Our findings suggest that pharmacovigilance may inform the shared-decision processes when choosing MS medications.

Impact of specialty pharmacy on telaprevir-containing 3-drug hepatitis C regimen persistence.

BACKGROUND: Although the recommended treatment of hepatitis C continues to evolve as newer and more effective medications are made available, hepatitis C drug regimens consisting of a 3-drug combination of a protease inhibitor, pegylated interferon, and ribavirin were recommended by the American Association for the Study of Liver Diseases for the HCV genotype I beginning in 2011. Although more effective than the earlier standard of care, these regimens have complex dosing schedules, prolonged duration, and deleterious side effects. It has been shown that patients tend to discontinue these regimens prematurely. Specialty pharmacies offer specialized care management programs to hepatitis C patients, consisting of such services as regularly scheduled patient counseling, assessing regimen appropriateness, monitoring treatment progress, scheduling refill reminders, and coordinating patient care with prescribers. The use of specialty pharmacies by hepatitis C patients may improve persistence on the 3-drug hepatitis C regimens. OBJECTIVE: To examine the association of pharmacy dispensing channel (specialty pharmacy or retail pharmacy) and hepatitis C regimen persistence among patients on a 3-drug hepatitis C regimen containing telaprevir, a widely used hepatitis C protease inhibitor.  METHODS: A retrospective, observational study was conducted using pharmacy claims data from a national pharmacy benefits manager for the period July 2011 to June 2013. Continuously eligible patients who started a new 3-drug regimen containing telaprevir were included in the study and followed for up to 12 months after the index hepatitis C claim. The study outcome was persistence to the 3-drug regimen at treatment week 24 (day 168), representing the completion of an important milestone in the regimen. Patients were defined as persistent if they filled 84 days' supply of telaprevir and 168 days' supply of pegylated interferon and ribavirin each, as required by the regimen protocol. Multivariate logistic regression was used to evaluate the association between dispensing channel and persistence, controlling for differences in demographics, medication burden, out-of-pocket spend per 30-day adjusted hepatitis C prescription, and average days' supply per unadjusted hepatitis C prescription. RESULTS: The final study sample consisted of 1,475 patients-1,182 in the specialty pharmacy group and 293 in the retail pharmacy group. A significantly greater proportion of patients were persistent to the 3-drug hepatitis C regimen containing telaprevir in specialty pharmacy, compared with retail pharmacy (56.0% vs. 39.9%, P less than 0.001). After multivariate adjustment, patients in the specialty pharmacy group had 1.89 times greater odds of being persistent to 3-drug hepatitis C regimens containing telaprevir compared with patients in the retail group (95% CI=1.44-2.48). CONCLUSIONS: Patients who used a specialty pharmacy offering refill reminders, care management, and care coordination with prescribers were significantly more likely to be persistent to 3-drug hepatitis C regimens, compared with patients using a retail pharmacy.

Activities of Memphis-area hospitals to meet National Patient Safety Goals for warfarin therapy.

PURPOSE: The activities of Memphis hospitals to meet National Patient Safety Goals (NPSGs) for warfarin therapy are described. SUMMARY: In March 2008, leadership from the Mid-South College of Clinical Pharmacy (MSCCP), a local chapter of the American College of Clinical Pharmacy, commissioned a task force on anticoagulation, comprising pharmacy administrators, clinical pharmacy practitioners, and pharmacy faculty from local hospitals within the greater Memphis area. The charge of the task force was to (1) identify practice variations in regard to NPSG.03.05.01, (2) develop professional collaboration among both academic and nonacademic institutions to share policy and protocol development, and (3) facilitate all institutions in meeting the deadlines set forth by the Joint Commission. The MSCCP Task Force on Anticoagulation project was successful in promoting collaboration among multiple institutions and clinical practitioners in the Memphis area. There was no one-size-fits-all approach; however, meetings and discussions were beneficial and led to idea generation. Having input from multiple institutions in different clinical settings with varying levels of experience created a rich environment from which all institutions benefited. For example, smaller institutions felt that they drew support for physician acceptance with protocol approval based on the knowledge of the policies approved or lessons learned at larger institutions. In addition, the larger institutions felt that the working group was helpful in validating their interpretation of the NPSG elements. CONCLUSION: The MSCCP Task Force on Anticoagulation project was successful in promoting collaboration among multiple institutions and clinical practitioners to offer solutions to meet NPSG.03.05.01 as it related to the needs of each institution.

Expedited discharge in trauma patients requiring anticoagulation for deep venous thrombosis prophylaxis: the LEAP Program.

OBJECTIVE: With rising health care costs, methods to decrease length of hospital stay without compromising care are necessary. One area that extends length of stay in trauma patients is inpatient anticoagulation to a therapeutic international normalized ratio. The 1998 American College of Chest Physicians guidelines recommend thromboprophylaxis with low-molecular-weight heparin (LMWH) and oral warfarin in this population. The LMWH Expedited Anticoagulation Program (LEAP) was created with the following goals: to decrease the number of inpatient warfarin days and to reduce overall number of hospital days. METHODS: Inpatient anticoagulation was initiated with warfarin and LMWH. LEAP included early multidisciplinary collaboration to ensure third-party approval, outpatient primary care physician follow-up, and LMWH self-injection before discharge. Patients were discharged on LMWH (discontinued by primary care provider when a therapeutic international normalized ratio was attained) and warfarin (continued until resolution of orthopedic injuries). From August 2000 to August 2001, adult patients were included in the prospective study. Primary inclusion criteria were blunt acetabular fracture, bilateral lower extremity fracture, and contralateral upper and lower extremity fractures. Patients with similar injuries receiving warfarin for deep venous thrombosis prophylaxis between June 1999 and June 2000 were the control population. Anticoagulation care was similar for the study and control subjects. RESULTS: There were 182 patients evaluated for LEAP inclusion. After initial evaluation, 108 patients were enrolled in LEAP (Injury Severity Score of 13). There were 69 control subjects (Injury Severity Score of 13). The average number of inpatient warfarin days was decreased from 8.8 days to 5.0 days in the control and study populations, respectively (p < 0.0001). The average length of hospitalization was shortened from 17.3 days in the control group to 12.9 days in the study (LEAP) population (p < 0.002). CONCLUSION: LEAP has successfully decreased the number of inpatient days on warfarin and total hospital days for trauma patients requiring deep venous thrombosis prophylaxis. These results have substantially decreased health care costs and increased available hospital beds in this era of high hospital occupancy.
