Social determinants of health and adult influenza vaccination: a nationwide claims analysis.

BACKGROUND: The health and economic benefits of the annual influenza vaccine are well documented, yet vaccination rates in the United States missed the Healthy People 2020 goal and remain a focus of Healthy People 2030 efforts. By identifying underlying reasons for low annual influenza vaccination, social elements that need targeting may be identified and could guide future interventions or policy development to achieve vaccination goals and improve overall public health. OBJECTIVE: To determine the influence of certain social determinants of health on adherence to annual influenza vaccination in American adults. METHODS: This was a retrospective cohort analysis using data from IBM MarketScan Commercial Claims and Encounters Database and national Medicare 5% sample data from 2013 to 2016. Study eligibility criteria included adults (aged 18 years and older) who were continuously enrolled for 3 influenza seasons between 2013 and 2016. Receipt of the influenza vaccine was counted over 3 consecutive influenza seasons, and select social determinants were extracted from publicly available sources. Patient characteristics, health resource utilization, and selected social determinants of health were included in bivariate and multivariate logistic regression analyses to determine their association with annual influenza vaccination. RESULTS: 6,694,571 adults across employer-sponsored and Medicare coverage groups were analyzed, of which 14.7% of Medicare-enrolled adults and 9.2% of commercially enrolled adults were vaccinated in all 3 seasons. Higher proportions of vaccine adherence (ie, all 3 seasons) were observed among females (9.6% vs 8.7% [commercial], 15.0% vs 14.4% [Medicare]), the immunocompromised (11.8% vs 8.3% [commercial], 15.9% vs 13.6% [Medicare]), rural residents (10.5% vs 9.0% [commercial], 15.4% vs 14.6% [Medicare]; all P < 0.0001), and those enrolled in a high-deductible health plan (10.3%). Multivariable logistic regression models indicated that the odds of vaccine adherence tended to be higher in areas of higher poverty (OR=1.012; 95% CI = 1.01-1.02 [commercial], OR=1.01; 95% CI = 1.01-1.01 [Medicare]) yet lower in areas with higher proportions of Democratic voters (OR=0.998; 95% CI = 0.998-0.998 [commercial], OR = 0.996; 95% CI = 0.996-0.997 [Medicare]). Among commercially insured adults, the odds of vaccine adherence were higher in areas of higher health literacy (OR=1.036; 95% CI = 1.036-1.037), but this effect was not observed among Medicare members. Conversely, the odds of vaccine adherence increased as the proportion of those residing in areas of limited Internet access increased (OR=1.007; 95% CI = 1.004-1.010) among Medicare members only. CONCLUSIONS: Key social determinants of health are important factors of vaccine adherence and can guide policy and intervention efforts toward addressing potential hesitancy. A deeper assessment of other contributing social factors is needed in seasonal influenza and other vaccines to better interpret the vaccine-seeking behaviors of adults. DISCLOSURES: This study received no outside funding. Gatwood, Hagemann, Hohmeier, and Chiu declare vaccine-related grant funding from Merck & Co. and GlaxoSmithKline for vaccine research unrelated to the current study. Ramachandran declares vaccine-related grant funding from Glaxo-SmithKline for research unrelated to the current study. Shuvo and Behal have nothing to disclose. Findings described in this study were presented as a poster and podium at the Academy of Managed Care Pharmacy Nexus 2020 Virtual meeting, October 19-23, 2020.

The role of social determinants in timely herpes zoster vaccination among older American adults.

CDC recommends that U.S. adults ≥50 years receive the herpes zoster (HZ) vaccine; but few are vaccinated at the recommended age. Little is known about how social determinants of health (SDH) influence timely vaccination. This retrospective observational study included U.S. adults aged ≥50 years who were vaccinated against HZ between 2014 and 2016 from IBM MarketScan commercial claims and Medicare supplemental databases. The cohort was classified into three groups based on age of vaccination: earlier (50-59 years), timely (60-64 years), and later (65+ years). Select SDH data from publicly-available sources were linked and included in multinomial logistic regression assessing the impact of SDH on timely vaccination. The final cohort comprised 549,544 individuals, 49.5% of whom were vaccinated at the age of 60-64. Odds of later HZ vaccination increased with higher poverty (OR: 1.035, 95% CI: 1.031-1.038), more democratic voters (OR: 1.011, 95% CI: 1.010-1.012), and lack of Internet access (OR: 1.028, 95% CI: 1.024-1.032), but decreased with higher health literacy (OR: 0.971, 95% CI: 0.970-0.973). Conversely, higher health literacy and lower poverty were associated with higher odds of earlier vaccination. Being male, not receiving a seasonal influenza vaccine, and higher healthcare utilization were associated with later vaccination. Individuals on an EPO/PPO vs. HMO plan, or who resided in regions other than the Northeast were more likely to receive the vaccine earlier. This study demonstrates the influence of SDH on time of HZ vaccination, but further research is needed to fully understand the impact of SDH on vaccination.

Pneumococcal vaccination in older adults: An initial analysis of social determinants of health and vaccine uptake.

OBJECTIVES: To examine the potential influence of social determinants of health on pneumococcal vaccination in older American adults. METHODS: This study used nationwide, US Medicare claims data from 2013 to 2016 to assess uptake of pneumococcal vaccination among adults in the first year after turning age 65. Patients were followed from the point of being 65 years of age and initially enrolled in traditional fee-for-service Medicare or a Medicare Advantage plan through the subsequent year and observed for pneumococcal vaccination in outpatient clinics and pharmacies. Publicly-available data on select social determinants of health were incorporated and guided by the World Health Organization vaccine hesitancy matrix. Logistic regression determined predictors of vaccination while controlling clinical and demographic characteristics. RESULTS: A total of 307,488 and 74,995 adults aged 65 years were identified from Medicare Advantage and Medicare fee-for-service claims, respectively, and 21.1% of Medicare Advantage and 38.2% of Medicare fee-for-service patients received a pneumococcal vaccine in the first year after turning 65. Those residing in urban areas had a higher likelihood of pneumococcal vaccination in both the Medicare Advantage (OR: 1.31; 95% CI: 1.267-1.344) and Medicare fee-for-service (OR: 1.53; 95% CI: 1.450-1.615) cohorts. Additionally, residing in areas of higher health literacy or communities with more democratic voters were consistently associated with a higher odds of pneumococcal vaccination regardless of Medicare type. Results also pointed to a synergistic relationship between receiving the influenza vaccine and also being vaccinated against pneumococcal disease. CONCLUSION: Social determinants of health, including local health literacy, poverty, residing in more liberal areas, and access to information, may be influencing the pneumococcal vaccine-related decisions of older adults. However, additional factors associated with the vaccine hesitancy matrix and more granular data (e.g., zip code-level) are needed to fully determine the impact in this and other vaccines recommended in older adults.

Assessing self-assessment practices: A survey of U.S. colleges and schools of pharmacy.

OBJECTIVE: This study quantifies and describes student self-assessment approaches in colleges of pharmacy across the United States. METHODS: Faculty members identified as assessment directors from college websites at U.S. colleges of pharmacy were electronically surveyed. Prior to distribution, feedback and question validation was sought from select assessment directors. Surveys were distributed and recorded, via Qualtrics® survey software and analyzed in Microsoft Excel®. RESULTS: Responses were received from 49 colleges of pharmacy (n = 49/134, 37% response rate). The most commonly used strategies were reflective essays (n = 44/49, 90%), portfolios (n = 40/49, 82%), student self-evaluations (n = 35/49, 71%) and questionnaires/surveys/checklists (n = 29/49, 59%). Out of 49 submitted surveys, 35 programs noted students received feedback on self-assessment. Feedback came most commonly from faculty (n = 31/35, 88%). Thirty-four programs responded regarding self-assessment integration including fifteen colleges (n = 15/34, 44%) that integrated self-assessment both into the curriculum and co-curricular activities, while 14 (n = 14/34, 41%) integrated self-assessment exclusively into the curriculum, and five (n = 5/34, 15%) used self-assessment exclusively in co-curricular activities. DISCUSSION AND CONCLUSIONS: Student self-assessment is a critical first step of the Continuing Professional Development (CPD) process. Colleges and schools of pharmacy use a wide variety of methods to develop this skill in preparing future practitioners.

Assessment of inpatient admissions and top 25 medications for obese pediatric patients at two academic hospitals.

PURPOSE: Inpatient admissions and the top 25 medications for obese pediatric patients at two academic hospitals were assessed. METHODS: Children age 2-17 years were included if they were obese and admitted to either hospital on or after January 1, 2011, and discharged before December 31, 2011. Obesity was defined as a body mass index of ≥95th percentile for age and sex. The objectives of this study were to determine the percentage of hospital admissions involving obese children and compile a list of medications prescribed to these patients. The top 25 medications prescribed were further evaluated to determine their pharmacokinetic disposition in obese patients. RESULTS: Obese children accounted for 18.8% of the 15,119 admissions for children age 2-17 years at the two study hospitals. No significant difference was noted in the number of obese pediatric children admitted between institutions. A total of 28,234 medications were ordered for this population, with a median number of 8 medications prescribed per admission. Sixteen of the same medications (64.0%) ranked in the top 25 at each facility. The most commonly prescribed medications for these patients included analgesics, antimicrobials, corticosteroids, bronchodilators, and gastrointestinal agents. CONCLUSION: Obese children accounted for 18.8% of admissions for patients age 2-17 years at two academic hospitals over a 1-year period. The most commonly prescribed medications for these children included analgesics, antimicrobials, corticosteroids, bronchodilators, and gastrointestinal agents. The literature guiding the dosing of these medications in this population was limited to seven studies, representing just three medications.

Recommendations for meeting the pediatric patient's need for a clinical pharmacist: a joint opinion of the Pediatrics Practice and Research Network of the American College of Clinical Pharmacy and the Pediatric Pharmacy Advocacy Group.

Children warrant access to care from clinical pharmacists trained in pediatrics. The American College of Clinical Pharmacy Pediatrics Practice and Research Network (ACCP Pediatrics PRN) released an opinion paper in 2005 with recommendations for improving the quality and quantity of pediatric pharmacy education in colleges of pharmacy, residency programs, and fellowships. Although progress has been made in increasing the availability of pediatric residencies, there is still much to be done to meet the direct care needs of pediatric patients. The purpose of this joint opinion paper is to outline strategies and recommendations for expanding the quality and capacity of pediatric clinical pharmacy practitioners by elevating the minimum expectations for pharmacists entering pediatric practice, standardizing pediatric pharmacy education, expanding the current number of pediatric clinical pharmacists, and creating an infrastructure for development of pediatric clinical pharmacists and clinical scientists. These recommendations may be used to provide both a conceptual framework and action items for schools of pharmacy, health care systems, and policymakers to work together to increase the quality and quantity of pediatric training, practice, and research initiatives.

Economic effect of an expansion of pharmacy benefits on total health care expenditures by a state Medicaid program.

OBJECTIVES: To evaluate the economic effect of a pharmacy benefit expansion on a population of Oklahoma Medicaid recipients and to determine whether recipients who routinely maximized their monthly prescription limit (cap) before the benefit expansion benefited more from the expansion than the remainder of the study population. DESIGN: Retrospective study. SETTING: Oklahoma Medicaid claims data from January 1, 2003, to December 31, 2004. PATIENTS: Data from 15,936 Oklahoma Medicaid recipients. INTERVENTION: Retrospective administrative analysis using the Oklahoma Health Care Authority pharmacy and medical claims databases. MAIN OUTCOME MEASURES: Total health care expenditures per recipient per year, total medical expenditures per recipient per year, and total pharmacy expenditures per recipient per year. RESULTS: Total health care expenditures increased 17% after the benefit expansion (P < 0.0001). Of this increase, 65% was attributed to pharmacy expenditures and 35% to medical expenditures. However, a subpopulation of recipients who routinely reached their prescription limit before the expansion had a statistically significant increase in total and pharmacy expenditures; a statistically significant increase in medical expenditures was not observed. CONCLUSION: Although total health care expenditures increased after a monthly pharmacy benefit in a Medicaid population was expanded, a subpopulation of recipients identified as high pharmacy users before the expansion did not have a statistically significant increase in medical expenditures, whereas those who were non-high users experienced a significant increase. Additionally, this subpopulation experienced a nonsignificant decrease in hospital expenditures. These results could suggest that this subpopulation was affected differently than the overall population by the expansion of the Medicaid pharmacy benefit.
