National surveys to evaluate prescribing practices: Methodological considerations

With the changing healthcare landscape, evaluating the care provision in ambulatory settings is vital to understand outpatient care. The national surveys such as the National Ambulatory Medical Care Survey (NAMCS) and the National Hospital Ambulatory Medical Care Survey (NHAMCS) are valuable resources to pharmacy researchers because of their availability and generalizability. With the recent focus on real-world data, the national surveys are critical in providing practice and policy evidence by evaluating ambulatory care, especially prescribing practices. The use of these surveys requires an understanding of the survey content, scope, complex sampling scheme, and analytical and research considerations. There are several methodological and practical considerations that make these national surveys useful to both novice and seasoned researchers. Although some generalized approaches are available for analyzing the national surveys, there is limited focus on the NAMCS and the NHAMCS. This paper provides an in-depth understanding of the NAMCS/NHAMCS, including methodological considerations for evaluating prescribing practices in ambulatory settings.

Automated summary

National surveys such as NAMCS and NHAMCS are valuable resources for pharmacy researchers to evaluate outpatient care. These surveys provide important practice and policy evidence for prescribing practices in ambulatory settings. Understanding the survey content, scope, complex sampling scheme, and methodological considerations is crucial for utilizing these surveys effectively.
