The Article in Brief
Solo and Small Practices: A Vital, Diverse Part of Primary Care
Winston R. Liaw , and colleagues
Background Solo and small practices are facing growing pressure to consolidate. This study sets out to determine the percentage of family physicians in solo and small practices and the characteristics of and services provided by these practices.
What This Study Found More than half of family physicians work in small and solo practices. Thirty-six percent of study respondents work in small practices and 15 percent work in solo practices. Small practices are the most likely to be located in a rural setting (20 percent). Small and solo practices are more common among African American, Hispanic and experienced physicians who have been in practice more than 30 years.
Implications
- Family physicians working in solo and small practices still outnumber those working in medium and large practices.
- These findings, the authors conclude, raise concerns about the types of physicians and communities that are being disproportionately affected by practice consolidation.
