Role of the National Health Service Corps in Delivering Substance Use Disorder Treatment in Underserved Communities

Behavioral Health Workforce Distribution in Socially Disadvantaged Communities

This study sought to understand the geographic distribution of three behavioral health clinician (BHC) types in disadvantaged communities in the U.S. across a standardized index of area disadvantage. CMS National Plan and Provider Enumeration System's data were used to identify BHC practice addresses. Addresses were geocoded and mapped to census block groups across Area Disadvantage Index (ADI) scores. Differences in the proportion of BHCs per 100k people in a block group by ADI, clinician type, and rurality were compared. Zero-inflated negative binomial models assessed associations between ADI score with any amount, and expected count, of BHC type in a block group. The sample included 836,780 BHCs (51.5% counselors, 34.5% social workers, 14.0% psychologists). Results indicated there were fewer BHCs in areas of high disadvantage with 351 BHCs in the lowest need versus 267 BHCs in highest need areas, per 100k people. BHC type was differently associated with the rate of clinicians per 100k by ADI and block groups that were both rural and high ADI had the least BHCs located. Findings suggest the maldistribution of BHCs by ADI underscores how some BHCs may be better positioned to meet the needs of vulnerable communities. Increasing access to behavioral health care requires a workforce equitably positioned in high-need areas. Reforms to payment and practice regulations may support BHCs to deliver services in socially disadvantaged neighborhoods.

Health professional retention in underserved areas: findings from the National Health Service Corps Loan Repayment Program participants in the United States, 2019-2021

Health care provider retention is important for mitigating workforce shortages in underserved areas. The National Health Service Corps (NHSC) provides loan repayment for a two or three-year service commitment from clinicians to work in underserved areas. Prior studies have mixed findings as to what influences clinician retention and have focused mainly on individual-level background characteristics. We used measures of NHSC clinicians' work environment during their service experience, in addition to background characteristics, to identify patterns of experiences, and assess whether these patterns were associated with post-service intentions. We observed that technical assistance and job resources were more influential on clinicians' intentions, compared to individual- or community-level characteristics. Organizations with efficient and supportive work environments may help retain clinicians in underserved areas.

Impact of U.S. Federal Loan Repayment Programs on the Behavioral Health Workforce: Scoping Review

OBJECTIVE

Federal loan repayment programs (LRPs) are one strategy to address the shortage of behavioral health providers. This scoping review aimed to identify and characterize the federal LRPs' impact on the U.S. behavioral health workforce.

METHODS

A scoping review was conducted in accordance with JBI (formerly known as the Joanna Briggs Institute) methodology for scoping reviews. The authors searched the Ovid MEDLINE, Web of Science, APA PsycInfo, EconLit, PAIS Index, and Embase databases, and gray literature was also reviewed. Two coders screened each article's abstract and full text and extracted study data. Findings were narratively synthesized and conceptually organized.

RESULTS

The full-text screening identified 17 articles that met eligibility criteria. Of these, eight were peer-reviewed studies, and all but one evaluated the National Health Service Corps (NHSC) LRP. Findings were conceptually organized into five categories: descriptive studies of NHSC behavioral health needs and the NHSC workforce (k=4); providers' perceptions of, and experiences with, the NHSC (k=2); associations between NHSC funding and the number of NHSC behavioral health providers (k=4); NHSC behavioral health workforce productivity and capacity (k=3); and federal LRP recruitment and retention (k=4).

CONCLUSIONS

The literature on federal LRPs and their impact on the behavioral health workforce is relatively limited. Although federal LRPs are an important and effective tool to address the behavioral health workforce shortage, additional federal policy strategies are needed to attract and retain behavioral health providers and to diversify the behavioral health workforce.

Preparing behavioral health clinicians for success and retention in rural safety net practices

PURPOSE

This study assesses how, among behavioral health clinicians working in rural safety net practices, the amount of exposure to care in rural underserved communities received during training relates to confidence in skills important in their work settings, successes in jobs and communities, and anticipated retention.

METHODS

This study uses survey data from Licensed Clinical Social Workers, Licensed Professional Counselors, and Psychologists working in rural safety net practices in 21 states while receiving educational loan repayment support from the National Health Service Corps, from 2015 to April 2022.

FINDINGS

Of the 778 survey respondents working in rural counties, 486 (62.5%) reported they had formal education experiences with medically underserved populations during their professional training, for a median of 47 weeks. In analyses adjusting for potential confounders, the estimated amount of rural training exposure was positively associated with a variety of indicators of clinicians' integration and fit with their communities as well as with longer anticipated retention within their rural safety net practices. The amount of training in care for rural underserved populations was not associated with clinicians' confidence levels in various professional skills or successes in their work, including connection with patients and work satisfaction.

CONCLUSIONS

Formal training in care for underserved populations is a large part of the education of behavioral health clinicians who later work in rural safety net practices. More training in rural underserved care for these clinicians is associated with greater integration and fit in their communities and longer anticipated retention in their practices, but not with skills confidence or practice outcomes.

Buprenorphine Prescribing and Challenges Faced Among National Health Service Corps Clinicians

Importance

The National Health Service Corps (NHSC) Loan Repayment Program (LRP) expansion in fiscal year (FY) 2019 intended to improve access to medication for opioid use disorder (MOUD) by adding more clinicians who could prescribe buprenorphine. However, some clinicians still face barriers to prescribing, which may vary between rural and nonrural areas.

Objective

To examine the growth in buprenorphine prescribing by NHSC clinicians for Medicaid beneficiaries during the NHSC LRP expansion and describe the challenges to prescribing that persist in rural and nonrural areas.

Design, Setting, and Participants

This cross-sectional study analyzed preexpansion and postexpansion Medicaid claims data to evaluate the percentage of prescriptions of buprenorphine filled during FY 2017 through 2021. This study also analyzed challenges and barriers to prescribing MOUD between rural and urban areas, using results from annual surveys conducted with NHSC clinicians and sites from FY 2019 through FY 2021.

Exposure

Prescribing of buprenorphine by NHSC clinicians.

Main Outcomes and Measures

The main outcomes were the percentage and number of Medicaid beneficiaries with opioid use disorder (OUD) who filled a prescription for buprenorphine before and after the LRP expansion and the challenges NHSC clinicians and sites faced in providing substance use disorder and OUD services. Survey results were analyzed using descriptive statistics.

Results

During FYs 2017 through 2021, 7828 NHSC clinicians prescribed buprenorphine (standard LRP: mean [SD] age, 38.1 [8.4] years and 4807 females [78.9%]; expansion LRPs: mean [SD] age, 39.4 [8.1] years and 1307 females [75.0%]). A total of 3297 NHSC clinicians and 4732 NHSC sites responded to at least 1 survey question to the 3 surveys. The overall percentage of Medicaid beneficiaries with OUD who filled a prescription for buprenorphine during the first 2.5 years post expansion increased significantly from 18.9% before to 43.7% after expansion (an increase of 123 422 beneficiaries; P < .001). The percentage more than doubled among beneficiaries living in areas with a high Social Vulnerability Index score (from 17.0% to 36.7%; an increase of 31 964) and among beneficiaries living in rural areas (from 20.8% to 55.7%; an increase of 45 523). However, 773 of 2140 clinicians (36.1%; 95% CI, 33.6%-38.6%) reported a lack of mental health services to complement medication for OUD treatment, and 290 of 1032 clinicians (28.1%; 95% CI, 24.7%-31.7%) reported that they did not prescribe buprenorphine due to a lack of supervision, mentorship, or peer consultation.

Conclusions and Relevance

These findings suggest that although the X-waiver requirement has been removed and Substance Abuse and Mental Health Services Administration guidelines encourage all eligible clinicians to screen and offer patients with OUD buprenorphine, as permissible by state law, more trained health care workers and improved care coordination for counseling and referral services are needed to support comprehensive OUD treatment.

Substance Use Disorder Program Availability in Safety-Net and Non-Safety-Net Hospitals in the US

Importance

Safety-net hospitals (SNHs) are ideal sites to deliver addiction treatment to patients with substance use disorders (SUDs), but the availability of these services within SNHs nationwide remains unknown.

Objective

To examine differences in the delivery of different SUD programs in SNHs vs non-SNHs across the US and to determine whether these differences are increased in certain types of SNHs depending on ownership.

Design, Setting, and Participants

This cross-sectional analysis used data from the 2021 American Hospital Association Annual Survey of Hospitals to examine the associations of safety-net status and ownership with the availability of SUD services at acute care hospitals in the US. Data analysis was performed from January to March 2022.

Main Outcomes and Measures

This study used 2 survey questions from the American Hospital Association survey to determine the delivery of 5 hospital-based SUD services: screening, consultation, inpatient treatment services, outpatient treatment services, and medications for opioid use disorder (MOUD).

Results

A total of 2846 hospitals were included: 409 were SNHs and 2437 were non-SNHs. The lowest proportion of hospitals reported offering inpatient treatment services (791 hospitals [27%]), followed by MOUD (1055 hospitals [37%]), and outpatient treatment services (1087 hospitals [38%]). The majority of hospitals reported offering consultation (1704 hospitals [60%]) and screening (2240 hospitals [79%]). In multivariable models, SNHs were significantly less likely to offer SUD services across all 5 categories of services (screening odds ratio [OR], 0.62 [95% CI, 0.48-0.76]; consultation OR, 0.62 [95% CI, 0.47-0.83]; inpatient services OR, 0.73 [95% CI, 0.55-0.97]; outpatient services OR, 0.76 [95% CI, 0.59-0.99]; MOUD OR, 0.6 [95% CI, 0.46-0.78]). With the exception of MOUD, public or for-profit SNHs did not differ significantly from their non-SNH counterparts. However, nonprofit SNHs were significantly less likely to offer all 5 SUD services compared with their non-SNH counterparts (screening OR, 0.52 [95% CI, 0.41-0.66]; consultation OR, 0.56 [95% CI, 0.44-0.73]; inpatient services OR, 0.45 [95% CI, 0.33-0.61]; outpatient services OR, 0.58 [95% CI, 0.44-0.76]; MOUD OR, 0.61 [95% CI, 0.46-0.79]).

Conclusions and Relevance

In this cross-sectional study of SNHs and non-SNHs, SNHs had significantly lower odds of offering the full range of SUD services. These findings add to a growing body of research suggesting that SNHs may face additional barriers to offering SUD programs. Further research is needed to understand these barriers and to identify strategies that support the adoption of evidence-based SUD programs in SNH settings.
