ABSTRACT
BACKGROUND: Pertussis can cause severe illness and death in infants. Immunization of family members with the tetanus toxoid, reduced diphtheria toxoids, and acellular pertussis (Tdap) vaccine can decrease risk of pertussis infection among infants. A community pharmacy on a women's hospital campus implemented a Tdap vaccination pilot program. OBJECTIVE: To investigate the rate of Tdap vaccination among close contacts of neonates in a women's hospital pharmacy and to assess the impact of a coordinated pharmacy and hospital Tdap vaccination program. METHODS: The intervention entailed education from hospital staff who explained the risks of pertussis, advocated the benefits of vaccination, and encouraged family members to be vaccinated. In the on-site clinic or in the pharmacy, pharmacists administered vaccine to eligible patients. Rates of Tdap vaccinations in the intervention pharmacy with in-hospital vaccination were compared to comparison pharmacies without Tdap interventions. RESULTS: In the pre-study period (December 2008-November 2010), there were 31 Tdap vaccinations administered at the intervention pharmacy (mean=1.3/month); during the study period (December 2010-November 2012), 2045 Tdap vaccinations were administered (mean=85.2/month). In four comparison hospital-campus pharmacies, there were 77 vaccinations (mean=0.8/month) during the pre-study period and 817 vaccinations (mean=8.5/month) during the study period. There were 155 vaccinations administered in 44 area-community pharmacies (mean=0.1/month) during the pre-study period and 2930 (mean=2.8/month) during the study period. The intervention pharmacy had the highest average monthly rate of change in Tdap volume from pre-study to study period (83.9), compared to comparison hospital-campus pharmacies (7.7, p<.001) and area-community pharmacies (2.7, p<.001). During the study period, the estimated Tdap vaccination coverage per live births was 8.1% in the intervention pharmacy versus 5.5% in the comparison hospital-campus pharmacies (p<.001). CONCLUSIONS: Tdap vaccination rates increased after implementation of the intervention program. This project illustrates how health systems and community pharmacists can collaborate to improve patient care.

PURPOSE: Approximately 50,000 adults die annually from vaccine-preventable diseases in the United States. Most traditional vaccine providers (eg, physician offices) administer vaccinations during standard clinic hours, but community pharmacies offer expanded hours that allow patients to be vaccinated at convenient times. We analyzed the types of vaccines administered and patient populations vaccinated during off-clinic hours in a national community pharmacy, and their implications for vaccination access and convenience. METHODS: We retrospectively reviewed data for all vaccinations given at the Walgreens pharmacy chain between August 2011 and July 2012. The time of vaccination was categorized as occurring during traditional hours (9:00 am-6:00 pm weekdays) or off-clinic hours, consisting of weekday evenings, weekends, and federal holidays. We compared demographic characteristics and types of vaccine. We used a logistic regression model to identify predictors of being vaccinated during off-clinic hours. RESULTS: During the study period, pharmacists administered 6,250,402 vaccinations, of which 30.5% were provided during off-clinic hours: 17.4% were provided on weekends, 10.2% on evenings, and 2.9% on holidays. Patients had significantly higher odds of off-clinic vaccination if they were younger than 65 years of age, were male, resided in an urban area, and did not have any chronic conditions. CONCLUSIONS: A large proportion of adults being vaccinated receive their vaccines during evening, weekend, and holiday hours at the pharmacy, when traditional vaccine providers are likely unavailable. Younger, working-aged, healthy adults, in particular, a variety of immunizations during off-clinic hours. With the low rates of adult and adolescent vaccination in the United States, community pharmacies are creating new opportunities for vaccination that expand access and convenience.

OBJECTIVE: To investigate how state-authorized pharmacist immunization privileges influence pharmacist intervention effectiveness in delivering pneumococcal and herpes zoster vaccinations and assess the implications these privileges have on vaccination rates. STUDY DESIGN: Cross-sectional study of Walgreens vaccination records from August 2011 to March 2012. METHODS: A random sample of patients having a claim for influenza vaccination in the study period was selected. Vaccination uptake rates for pneumococcal disease and herpes zoster were calculated for previously unvaccinated patients at high risk for these conditions. Rates were examined by state-level pharmacist privileges. RESULTS: For states authorizing immunization by protocol or prescriptive authority, the 1-year pneumococcal vaccination uptake rate for previously unvaccinated, high-risk persons was 6.6%, compared with 2.5% for states requiring a prescription (P <.0001), and 2.8% for states with no authorization (P <.0001). For herpes zoster, the 1-year vaccination uptake rate was 3.3% for states authorizing per protocol/prescriptive authority, compared with 2.8% (not significant, P <.05) for states authorizing by prescription, and 1.0% for states with no authorization (P <.0001). A 148% increase of pneumococcal vaccination and a 77% increase of herpes zoster vaccination would result if all states granted pharmacists full immunization privileges. CONCLUSIONS: This analysis demonstrates that states that offer pharmacists full immunization privileges have higher vaccination uptake rates than states with restricted or no authorization. Considering the suboptimal vaccination rates of pneumonia and shingles and the public health goals of 2020, states with limited or no immunization authorization for pharmacists should consider expanding pharmacist privileges for these vaccinations.

BACKGROUND: In an attempt to contain Medicaid pharmacy costs, nearly all states impose dispensing limits on medication days' supply. Although longer days' supply appears to increase the potential for medication wastage, previous studies suggest that it may also decrease pharmacy expenditures by reducing dispensing fees and drug ingredient costs. This study was conducted to determine whether 90-day refills at community pharmacies could improve adherence, minimize wastage, and control costs. METHODS: This retrospective observational study used California Medicaid claims, from the Walgreens pharmacy chain dated January 2010, to identify 52,898 patients prescribed statin, antihypertensive, selective serotonin reuptake inhibitor (SSRI), or oral hypoglycemic medications. Adherence was measured by medication possession ratio (MPR) and persistency with a 30-day gap. Medication wastage was defined as a switch of drug or drug strength within the same therapeutic class that occurred before the expected refill date. RESULTS: Adherence was 20% higher and persistency was 23% higher for the 90-day group than the 30-day group. This amounted to an average increase of 0.14 MPR and 44 days of continuous therapy. The two groups had comparable proportions of patients with wastage. After subtracting an average wastage cost of $7.34 per person per year (PPPY), all therapeutic classes had PPPY savings: statins ($7.70), antihypertensives ($10.80), SSRIs ($18.52), and oral hypoglycemics ($26.86). CONCLUSION: Across four drug categories and compared to 30-day refills, patients with 90-day refills had greater medication adherence, greater persistency, nominal wastage, and greater savings.
