Table 1.
Mean depth, safety-net composition, and spread by chain status (2022).
| Total US pharmacies | No. with 1+ contracts | Proportion of locations with 1+ contracts | Proportion of all contracts | Depth, median (IQR) | Geographic spread, median (IQR) |
Proportion of contracts with safety-net providers, mean (SD) | |
|---|---|---|---|---|---|---|---|
| Top 4 chains | 26 490 | 18 761 | 71% | 78% | 2 (1–4) | 19 (8–39) | 75% (34%) |
| Grocery stores | 9053 | 3481 | 38% | 9% | 1 (1–2) | 12 (5–27) | 63% (42%) |
| Small chains | 1102 | 453 | 19% | 1% | 2 (1–3) | 18 (4–34) | 49% (44%) |
| Institution | 6504 | 1418 | 41% | 3% | 1 (1–2) | 10 (1–27) | 61% (45%) |
| Independent | 14 767 | 2772 | 22% | 8% | 1 (1–2) | 10 (1–26) | 69% (44%) |
The table shows the count of all pharmacies in the United States, regardless of 340B participation, the number of pharmacies with at least 1 contract, the proportion of each type of pharmacy’s sites with at least 1 contract, and the proportion of total contracts between covered entities and each type of pharmacy. The table also displays the median and interquartile range (IQR) of the number of contract depth (number of contracts per site) and geographical spread (distance from the farthest contract pharmacy in miles). The final column presents the mean and standard deviation (SD) of safety-net composition (the share of each pharmacy types’ contracts with core safety-net providers). The top 4 chains include the top 4 retail chains by market share (Walgreens, CVS, Walmart, and Rite Aid), grocery store chains, small chains, institutional pharmacies, and independent pharmacies. n = 57 916 for all pharmacies in the United States, n = 26 980 for pharmacies participating in 340B.
