Visits for Depression to Physician Assistants and Nurse Practitioners in the USA

Physician assistants/associates in psychiatry: a workforce analysis

BACKGROUND

Physician assistants/associates (PAs) provide services in diverse medical specialties globally, including psychiatry. While health professionals in psychiatry have been described for many years, little is known about PAs practicing in this discipline.

METHODS

We describe US PAs practicing in psychiatry using robust national data from the National Commission on Certification of Physician Assistants (NCCPA). Analyses included descriptive and inferential statistics comparing PAs in psychiatry to PAs in all other medical and surgical specialties.

RESULTS

The percentage of PAs practicing in psychiatry has increased from 1.1% (n = 630) in 2013 to 2.0% (n = 2 262) in 2021. PAs in psychiatry differed from PAs practicing in all other specialties in the following: they identified predominately as female (71.4% vs. 69.1%; p = 0.016), were more racially diverse (Asian [6.6% vs. 6.0%], Black/African American [5.5% vs. 3.4%], multi-race [2.8% vs. 2.1%], and other races [Native Hawaiian/Pacific Islander, American Indian/Alaska Native, or other; 3.7% vs. 3.6%]; p < 0.001), and resided in the South (43.8% vs. 34.1%; p < 0.001). PAs in psychiatry vs. all other specialties were more likely to work in office-based private practice settings (41.6% vs. 37.3%; p < 0.001) and nearly twice as likely to provide telemedicine services for their patients (62.7% vs. 32.9%; p < 0.001). While one-third (31.9%) of PAs in psychiatry experienced one or more burnout symptoms, and 8.1% considered changing their current position, the vast majority of PAs in psychiatry (86.0%) were satisfied with their position.

CONCLUSIONS

Understanding the attributes of PAs in psychiatry is essential in medical labor supply and demand research. Our findings suggest that the number of PAs working in psychiatry is steadily increasing. These PAs were predominantly female, exhibited greater racial diversity, and were primarily located in the South and Midwest regions of the US. A striking difference was that PAs in psychiatry were almost twice as likely to provide telemedicine services for their patients. Although nearly a third of PAs in psychiatry acknowledged having one or more symptoms of burnout, few were considering changing their employment, and the vast majority reported high job satisfaction.

The role of PAs in providing mental health care

The prevalence of psychiatric and substance use disorders in the United States is rising and of growing concern. Because such behavioral conditions are widespread, one approach is to collaborate with various medical professionals to help offset this demand. To address this issue, the frequency and types of mental health conditions encountered by physician assistants (PAs) were assessed. The National Commission on the Certification of Physician Assistants Practice Analysis was examined for the types of mental health conditions encountered across the spectrum of medical and surgical practices. The findings reveal that, in 2015, at least 62% of PAs saw and evaluated mental health conditions and behavioral disorders at least weekly in their settings. These patient diagnoses were seen with variability based on the specialty of the PA. The highest percentage of cases reported by PAs were in psychiatry, followed by general internal medicine, emergency medicine, family medicine, and hospital medicine. With the profession projected to grow, recruiting, retaining, and integrating more PAs into mental health care is a suggested strategy for addressing national provider shortages.

The relationship between dietary patterns and depression mediated by serum levels of Folate and vitamin B12

BACKGROUND

Major depressive disorder is among main worldwide causes of disability. The low medication compliance rates in depressed patients as well as the high recurrence rate of the disease can bring up the nutrition-related factors as a potential preventive or treatment agent for depression. The aim of this study was to investigate the association between dietary patterns and depression via the intermediary role of the serum folate and vitamin B12, total homocysteine, tryptophan, and tryptophan/competing amino acids ratio.

METHODS

This was an individually matched case-control study in which 110 patients with depression and 220 healthy individuals, who completed a semi-quantitative food frequency questionnaire were recruited. We selected the depressed patients from three districts in Tehran through non-probable convenience sampling from which healthy individuals were selected, as well. The samples selection and data collection were performed during October 2012 to June 2013. In addition, to measure the serum biomarkers 43 patients with depression and 43 healthy people were randomly selected from the study population. To diagnose depression the criteria of Diagnostic and Statistical Manual of Mental Disorders, fourth edition, were utilized.

RESULTS

The findings suggest that the healthy dietary pattern was significantly associated with a reduced odds of depression (OR: 0.75; 95% CI: 0.61-0.93) whereas the unhealthy dietary pattern increased it (OR: 1.382, CI: 1.116-1.71). The mediation analysis showed that the healthy dietary pattern was associated with a reduced risk of depression via increased serum levels of the folate and vitamin B12; however, the unhealthy dietary pattern was associated with increased risk of depression via decreased serum levels of folate and vitamin B12, based on tree adjusted logistic regression models.

CONCLUSION

Dietary patterns may be associated with depression by changing the serum levels of folate and vitamin B12. Further studies are required to confirm the mechanism.

Physical Activity Health Communication for Adults With Mood Disorders in the United States

Using national representative data, this study sought to examine receipt of physical activity communication and counseling among adults with mood disorders in comparison to the general population in the United States. The sample consisted of adult primary-care visits in the National Hospital Ambulatory Medical Care and National Ambulatory Medical Care Surveys. Multivariable logistic regression was used to examine the relationship between mental health status and receipt of physical activity communication and counseling. Overall, less than 20% of visits included physical activity communication and counseling. Controlling for covariates, visits for adults with a mood disorder diagnosis were associated with an increased odds of including physical activity communication and counseling, odds ratio = 1.25, 95% confidence interval = [1.08, 1.45]. Although adults with mood disorders were more likely to receive physical activity communication and counseling, most primary-care visits for adults in the United States did not include physical activity communication and counseling.
