Insight into U.S. pharmacy deserts

A state-by-state look at the impact of pharmacy closures across the United States

Currently, there are growing concerns in the U.S. over the limited access to pharmacies in certain areas. In the United States there are 150 counties where there is no pharmacy, and nearly 4.8 million people who live in a county where there’s only one pharmacy for every 10,000 residents or more [1]. In recent years, several factors, including reimbursement challenges, rising costs, changing consumer behavior, and staff shortages, have forced many pharmacies to close, further worsening access to pharmacy services.

Pharmacy closures can lead to a rise of pharmacy deserts, meaning that there is no retail pharmacy within 1 mile (in urban areas), 2 miles (in suburban areas), or 10 miles (in rural areas) from an individual household [2]. Households located in pharmacy deserts must travel farther to get prescriptions, vaccines, screenings, and other necessary services inherent for healthy communities.

Cencora’s Enterprise Data & Analytics team built a dashboard with data and insight into pharmacy deserts and other socially vulnerable communities across the United States.

Based on our data methodology, an estimated 30 million [3] people live in U.S. pharmacy deserts. Once formed, such deserts are not just disruptive to care but also dangerous. Dima Qato, PharmD, MPH, PhD, a well-known pioneer in pharmacy desert research and now an associate professor of pharmacy at University of Southern California, has long warned about the dangers of pharmacy deserts, such as medication discontinuation and non-adherence (even for lifesaving drugs like statins) [4].

Pharmacy deserts disproportionately impact populations with lower socio-economic statuses and racial and ethnic minorities from the Hispanic/Latino and Black or African American communities [5]. However, other dimensions, like disability status and English-language proficiency, can also impact population social vulnerability and the amount of additional support they could need [6].

Community pharmacies can be an important part of the solution, not only to address medication non-adherence, but also by serving more broadly as sites of care in their communities.

FAQs

What data sources and methodology were uses to identify U.S. pharmacy deserts?

The dashboard utilizes publicly available demographic data from the Centers for Disease Control and Prevention (CDC), the U.S. Census Bureau, and other statistical data available from the United States Department of Transportation and the NTIA (National Telecommunications and Information Administration). The data is extracted from these sources “as-is” and incorporated into geospatial analysis with only minimal transformation necessary for analysis. Gaps in the data sets are shown as NULL in the dashboard. The dashboard also utilizes NCPDP (National Council for Prescription Drug Programs) data for pharmacy location and pharmacy type attributes for every pharmacy in the United States. The NCPDP pharmacy directory is a commercially available data set described as the most timely, complete, and accurate pharmacy database available. For purposes of Pharmacy Desert analysis, only open/active pharmacy locations and provider/dispensary types of “Chain”, “Retail” and “Independent” were included in the analysis. Other pharmacy types (mail order, government, specialty, LTC, etc.) were excluded from scope as our focus was understanding pharmacy access through typical channels open to the public.

Is the data real-time?

As of August 7, 2024, this dashboard displays the most recent demographic estimates and statistical data available, sourced from government data sets below. Government data provided is from the year 2020 or 2021 (see “year in application” in table below). The NCPDP pharmacy data is as of the 5/2/23 snapshot date.

Note: The NCPDP source provides data updates on a weekly cadence, however for the purposes of formalizing and validating geospatial results, the data has not been updated since the original date of our analysis.
