Impact of Pharmacists on Access to Vaccine Providers: A Geospatial Analysis.

ABSTRACT: Policy Points: Policymakers in the United States should consider expanding pharmacy practice laws to allow pharmacists to vaccinate adolescents as a way to improve geographic access to adolescent vaccines, particularly for human papillomavirus (HPV) vaccine, which has low uptake. Our state-level analysis showed that pharmacists are more geographically dispersed than primary care physicians in the US state of Texas. Including pharmacists among available adolescent vaccine providers would improve the geographic distribution of vaccine providers, especially in areas with an inadequate number of primary care physicians. CONTEXT:The largest disparities in human papillomavirus (HPV) vaccination in the United States are due to geography. One potential way of addressing these disparities is by improving geographic access to HPV vaccination. Two federal panels have recommended including community pharmacists as HPV vaccine providers as a strategy to improve opportunities for HPV vaccination for adolescents. We sought to evaluate whether community pharmacists can improve the number of vaccine providers in areas with primary care physician shortages in the US state of Texas. METHODS:We gathered publicly available physician and pharmacist 2016 workforce data from the Texas Medical Board and Board of Pharmacy. We conducted geospatial analysis of census tracts to analyze the distribution of physicians and pharmacists and how pharmacists change vaccine provider coverage across the state. FINDINGS:Census tracts with high numbers of physicians per capita tended to be located near one another, in 5 of 5 analyses of Moran's I (median = .04). In contrast, pharmacist rates were not spatially dependent on census tract in any of our analyses. If pharmacists were added to primary care physicians as vaccine providers, 35% of urban census tracts that previously had inadequate coverage would be adequately covered, while 18% of inadequately covered rural census tracts would become adequately covered. Overall, when pharmacists were included with primary care physicians as vaccine providers, vaccine providers per capita increased in 2,413 of the 4,508 urban census tracts (54%), while the rate increased in 223 of 746 rural census tracts (30%). CONCLUSIONS:Pharmacists are more geographically dispersed across census tracts than primary care physicians. As a result, adding pharmacists to the workforce would increase the availability of vaccine providers in areas with inadequate primary care provider coverage.

Project description:The role of pharmacy in healthcare continues to evolve as pharmacists gain increased clinical responsibilities in the United States, such as the opportunity to prescribe hormonal contraception. Currently, North Carolina (NC) pharmacists do not have this ability. While previous research focused on the perceptions of community pharmacists surrounding this practice, no previous research surveyed all pharmacists in a state. This cross-sectional, web-based survey was distributed to all actively licensed pharmacists residing in the state of NC in November 2018. The primary objective was to determine the likelihood of NC community pharmacists to prescribe hormonal contraception. Secondary outcomes included: evaluation of all respondent support and perceptions of this practice as advocacy occurs on the state organization level and unified support is critical; opinions regarding over-the-counter (OTC) status of contraception; and potential barriers to prescribing. Overall, 83% of community pharmacists were likely to prescribe hormonal contraception. No differences in likelihood to prescribe were detected between geographic settings. Community pharmacists reported that the most common barriers to impact prescribing were added responsibility and liability (69.8%) and time constraints (67.2%). Fewer than 10% of respondents felt that hormonal contraception should be classified as OTC (7.9%). Noncommunity pharmacists were significantly more likely to agree that prescribing hormonal contraception allows pharmacists to practice at a higher level, that increased access to hormonal contraception is an important public health issue, and that rural areas would benefit from pharmacist-prescribed hormonal contraception. Overall, this study found a willingness to prescribe and support from the majority of both community and noncommunity pharmacists. Limitations of the study included a low response rate and potential nonresponse bias. Future research is needed to address solutions to potential barriers and uptake of this practice, if implemented.

Project description:BackgroundIn conflict settings, data to guide humanitarian and development responses are often scarce. Although geospatial analyses have been used to estimate health-care access in many countries, such techniques have not been widely applied to inform real-time operations in protracted health emergencies. Doing so could provide a more robust approach for identifying and prioritising populations in need, targeting assistance, and assessing impact. We aimed to use geospatial analyses to overcome such data gaps in Yemen, the site of one of the world's worst ongoing humanitarian crises.MethodsWe derived geospatial coordinates, functionality, and service availability data for Yemen health facilities from the Health Resources and Services Availability Monitoring System assessment done by WHO and the Yemen Ministry of Public Health and Population. We modelled population spatial distribution using high-resolution satellite imagery, UN population estimates, and census data. A road network grid was built from OpenStreetMap and satellite data and modified using UN Yemen Logistics Cluster data and other datasets to account for lines of conflict and road accessibility. Using this information, we created a geospatial network model to deduce the travel time of Yemeni people to their nearest health-care facilities.FindingsIn 2018, we estimated that nearly 8·8 million (30·6%) of the total estimated Yemeni population of 28·7 million people lived more than 30-min travel time from the nearest fully or partially functional public primary health-care facility, and more than 12·1 million (42·4%) Yemeni people lived more than 1 h from the nearest fully or partially functional public hospital, assuming access to motorised transport. We found that access varied widely by district and type of health service, with almost 40% of the population living more than 2 h from comprehensive emergency obstetric and surgical care. We identified and ranked districts according to the number of people living beyond acceptable travel times to facilities and services. We found substantial variability in access and that many front-line districts were among those with the poorest access.InterpretationThese findings provide the most comprehensive estimates of geographical access to health care in Yemen since the outbreak of the current conflict, and they provide proof of concept for how geospatial techniques can be used to address data gaps and rigorously inform health programming. Such information is of crucial importance for humanitarian and development organisations seeking to improve effectiveness and accountability.FundingGlobal Financing Facility for Women, Children, and Adolescents Trust Fund; Development and Data Science grant; and the Yemen Emergency Health and Nutrition Project, a partnership between the World Bank, UNICEF, and WHO.
