Collaborative practice trends in US physician office visits: an analysis of the National Ambulatory Medical Care Survey (NAMCS), 2007-2016

Utilizing Federal Data Sources to Support Nursing Workforce Analysis

Effective health workforce analysis requires robust data and information. Quality data facilitate monitoring workforce trends, identifying shortages, forecasting employment needs, and planning educational programs. A wide range of federal agencies collect various forms of data, including administrative data, surveys, and censuses, which can be used for health workforce analysis. However, identifying the most appropriate data sources to address a specific nursing workforce issue can be challenging, particularly for newcomers to the field or those researching unfamiliar topics. In this article, we introduce and review 18 federal data sources pertinent to nursing workforce analysis. We categorize the datasets by their associated federal agency, describe each source, discuss their applicability to nursing workforce studies, present examples of past studies that employed these datasets, and highlight their limitations. Our aim is to help researchers, policymakers, and healthcare administrators efficiently locate and leverage relevant data for their analysis.

Provision of evaluation and management visits by nurse practitioners and physician assistants in the USA from 2013 to 2019: cross-sectional time series study

OBJECTIVE

To examine the proportion of healthcare visits are delivered by nurse practitioners and physician assistants versus physicians and how this has changed over time and by clinical setting, diagnosis, and patient demographics.

DESIGN

Cross-sectional time series study.

SETTING

National data from the traditional Medicare insurance program in the USA.

PARTICIPANTS

Of people using Medicare (ie, those older than 65 years, permanently disabled, and people with end stage renal disease), a 20% random sample was taken.

MAIN OUTCOME MEASURES

The proportion of physician, nurse practitioner, and physician assistant visits in the outpatient and skilled nursing facility settings delivered by physicians, nurse practitioners, and physician assistants, and how this proportion varies by type of visit and diagnosis.

RESULTS

From 1 January 2013 to 31 December 2019, 276 million visits were included in the sample. The proportion of all visits delivered by nurse practitioners and physician assistants in a year increased from 14.0% (95% confidence interval 14.0% to 14.0%) to 25.6% (25.6% to 25.6%). In 2019, the proportion of visits delivered by a nurse practitioner or physician assistant varied across conditions, ranging from 13.2% for eye disorders and 20.4% for hypertension to 36.7% for anxiety disorders and 41.5% for respiratory infections. Among all patients with at least one visit in 2019, 41.9% had one or more nurse practitioner or physician assistant visits. Compared with patients who had no visits from a nurse practitioner or physician assistant, the likelihood of receiving any care was greatest among patients who were lower income (2.9% greater), rural residents (19.7%), and disabled (5.6%).

CONCLUSION

The proportion of visits delivered by nurse practitioners and physician assistants in the USA is increasing rapidly and now accounts for a quarter of all healthcare visits.

Physician Associates/Assistants in Primary Care: Policy and Value

Since the new century, primary care physician supply has worsened. Analysts predict that health service demand in the United States will grow faster than physician supply. One strategy is the utilization of physician assistants/associates (PAs). Most PAs work full-time, and approximately one quarter are employed in family medicine/general medicine. PAs deliver primary care services in a team-oriented fashion in a wide variety of settings, including private health systems and community health centers. One fifth work in rural and medically underserved areas. Together PAs and nurse practitioners provide approximately one third of the medical services in family medicine, urgent care, and emergency medicine.

The effect of team-based care practice on productivity for family physicians

ABSTRACT

About 60% of family physician practices employ PAs and/or NPs but gaps exist in the knowledge of the clinical effects on physician-PA and physician-NP teams. This review summarizes and comments on the significance of a recent report from the American Board of Family Medicine that compares the scope of practice of family physicians for family physicians practicing with either a PA, NP, or both.

Trends in utilization of non-first-line topical acne medications among children, adolescents, and adults in the United States, 2012-2016

BACKGROUND/OBJECTIVE

Current knowledge about usage of effective, but non-first-line topical acne medications in the United States is limited. We aimed to investigate utilization patterns and temporal trends for such acne medications in the US ambulatory care.

METHODS

Pediatric (≤18 years old) and adult (>18 years old) data from the 2012 to 2016 (inclusive) cycles of the US National Ambulatory Medical Care Survey were extracted. Utilization patterns of six non-first-line topical acne medications (ie, azelaic acid, salicylic acid, glycolic acid, sulfur, resorcinol, and zinc) were compared and followed over time.

RESULTS

Data from 218 410 US office-based sampled visits during 2012-2016 were included in the analysis. Across all acne visits (n = 1542), salicylic acid (1.58%), azelaic acid (1.22%), and glycolic acid (0.52%) were the most frequently used agents, while zinc and resorcinol were not used. Sulfur (0.52%) and salicylic acid (0.33%) were the only medications used in preadolescents, and none of these medications were used in the neonatal or infantile group. Temporal trends for using at least one of these medications were insignificant among both pediatric and adult age groups (P = .825 and .136, respectively).

CONCLUSIONS

Salicylic acid and azelaic acid are the most frequently used of the studied second-line medications to treat acne, although the use of these and the other non-first-line topical medications overall is uncommon, especially among younger groups of US pediatric patients.

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.
