Beyond Disease Intervention: Exploring an Expanded Role for Partner Services in the MATRix-NC Demonstration Project

Disease Intervention Specialist-Delivered Interventions and Other Partner Services for HIV and Sexually Transmitted Infections: A Systematic Review

INTRODUCTION

Disease intervention specialists (DIS) are critical for delivering partner services programs that provide partner notification, counseling, referral, and other services for HIV, sexually transmitted infections (STIs), and other infections. This systematic review of partner services and other DIS-delivered interventions for HIV and STIs was conducted to summarize the effectiveness of these programs and identify evidence gaps.

METHODS

A systematic literature review was conducted with a narrative synthesis. Articles were located using keyword searches in MEDLINE, Web of Science, CINAHL, and ProQuest through December 2022 and analyzed in 2023-2024. Included studies addressed an intervention of partner services or other DIS-delivered services for HIV or STIs; a United States setting; primary data collection; and an external comparison group or pre-post design.

RESULTS

A total of 1,915 unique records were screened for eligibility, with 30 studies included. Overall, DIS-delivered interventions improved clinical outcomes among index patients and population outcomes. Many studies focused on program process measures rather than population-level epidemiologic outcomes. All but one studies were scored as having low or medium strength of evidence.

CONCLUSIONS

The evidence could be strengthened by establishing a streamlined set of core metrics, assessing impact using rigorous causal inference methodologies, linking program and clinical data systems, and supplementing impact evaluations with evidence on implementation strategies.

A Scoping Review of Health Equity Interventions in Governmental Public Health

CONTEXT

Despite major efforts in research, practice, and policy, racial and ethnic disparities in health and health care persist in the United States. Interventions in collaboration with governmental public health may provide ways to address these persistent racial and ethnic health and health care disparities and improve health outcomes.

OBJECTIVE

To conduct a comprehensive review of health equity interventions performed in collaboration with public health agencies.

DESIGN

This scoping review includes intervention studies from Ovid MEDLINE, PsycINFO, and Academic Search Premier, published between 2017 and 2023. The search strategy used terminology focused on 4 concepts: race/ethnicity, equity, health departments, and epidemiologic studies.

ELIGIBILITY CRITERIA

The following inclusion criteria were determined a priori: (1) intervention tailored to reduce racial/ethnic health disparities, (2) public health department involvement, (3) health outcome measures, (4) use of epidemiologic study methods, (5) written in English, (6) implemented in the United States, (7) original data (not a commentary), and (8) published between January 2017 and January 2023.

MAIN OUTCOME MEASURES

This review focused primarily on 4 dimensions of racial health equity interventions including intervention components, intervention settings, intervention delivery agents, and intervention outcomes.

RESULTS

This review indicated that health equity interventions involving public health agencies focused on the following categories: (1) access to care, (2) health behavior, (3) infectious disease testing, (4) preventing transmission, and (5) cancer screening. Critical strategies included in interventions for reaching racial/ethnic minoritized people included using community settings, mobile clinics, social media/social networks, phone-based interventions, community-based workers, health education, active public health department involvement, and structural/policy change.

CONCLUSIONS

This scoping review aims to provide an evidence map to inform public health agencies, researchers, and funding agencies on gaps in knowledge and priority areas for future research and to identify existing health equity interventions that could be considered for implementation by public health leaders.

Costs Associated With Incorporation of Network Approaches Into Sexually Transmitted Disease Program Activities

BACKGROUND

Network approaches can be used to study sociosexual partnerships and identify individuals at high risk of infection. Little is known about the cost structure of these services and their association with STD diagnoses.

METHOD

We collected costs associated with using a peer network strategy to recruit men who have sex with men and transwomen of color in 4 counties in North Carolina: Guilford, Forsyth, Durham, and Wake from February through October 2019. We used a comprehensive costing approach to gather detailed retrospective information on the intervention cost, broken down by category and programmatic activity.

RESULTS

The sociosexual networks collected consisted of 31 initial seeds (index cases) and 49 peers of those seeds. In peers, 5 cases of human immunodeficiency virus (HIV) and 10 cases of syphilis were identified. The cost per case (HIV or syphilis) identified was $7325. Personnel costs accounted for 80% of total expenditures, followed by laboratory expenses (12%). Personnel cost was distributed between disease intervention specialist patient navigators (51%), nonclinical (37%), and management (12%) staff. General administration was the costliest programmatic activity (37%), followed by case management and field services (37%), and study activities (11%). The estimated average cost per patient tested was $2242.

CONCLUSIONS

Finding positive peer cases in nonclinical settings is costly but may be crucial for limiting the spread of sexually transmitted diseases. The cost of staff was the major driver. This study demonstrates that using a network strategy can be a cost-effective way to identify, test, and refer patients at high risk of syphilis and HIV infections to care.
