Long-term follow-up after voluntary human immunodeficiency virus/sexually transmitted infection counseling, point-of-service testing, and referral to substance abuse treatment from the emergency department

Precision emergency medicine

BACKGROUND

Precision health is a burgeoning scientific discipline that aims to incorporate individual variability in biological, behavioral, and social factors to develop personalized health solutions. To date, emergency medicine has not deeply engaged in the precision health movement. However, rapid advances in health technology, data science, and medical informatics offer new opportunities for emergency medicine to realize the promises of precision health.

METHODS

In this article, we conceptualize precision emergency medicine as an emerging paradigm and identify key drivers of its implementation into current and future clinical practice. We acknowledge important obstacles to the specialty-wide adoption of precision emergency medicine and offer solutions that conceive a successful path forward.

RESULTS

Precision emergency medicine is defined as the use of information and technology to deliver acute care effectively, efficiently, and authentically to individual patients and their communities. Key drivers and opportunities include leveraging human data, capitalizing on technology and digital tools, providing deliberate access to care, advancing population health, and reimagining provider education and roles. Overcoming challenges in equity, privacy, and cost is essential for success. We close with a call to action to proactively incorporate precision health into the clinical practice of emergency medicine, the training of future emergency physicians, and the research agenda of the specialty.

CONCLUSIONS

Precision emergency medicine leverages new technology and data-driven artificial intelligence to advance diagnostic testing, individualize patient care plans and therapeutics, and strategically refine the convergence of the health system and the community.

HIV Voluntary Counseling and Testing (VCT-HIV) effectiveness for sexual risk-reduction among key populations: A systematic review and meta-analysis

Background

HIV disproportionately affects people who inject drugs, transgender people, sex workers, men who have sex with men, and incarcerated people. Recognized as key populations (KP), these groups face increased impact of HIV infection and reduced access to health assistance. In 1990, the Center for Disease Control and Prevention organized technical guidance on HIV Voluntary Counseling and Testing (VCT-HIV), with subsequent trials comparing intervention methodologies, no longer recommending this strategy. However, KP needs have not been explicitly considered.

Methods

We assessed VCT-HIV effectiveness for sexual risk-reduction among KP (PROSPERO 2020 CRD42020088816). We searched Pubmed, EMBASE, Global Health, Scopus, PsycINFO, and Web of Science for peer-reviewed, controlled trials from February, 2020, to April, 2022. We screened the references list and contacted the main authors, extracted data through Covidence, applied the Cochrane Risk-of-Bias tool, and performed the meta-analysis using Review Manager.

Findings

We identified 17 eligible trials, including 10,916 participants and evaluated HIV risk behaviors. When compared to baseline, VCT-HIV reduced unsafe sex frequency (Z=5.40; p<0.00001, I²=0%).

Interpretation

While our meta-analysis identified VCT-HIV as protective for sexual risk behaviors for among KP, the results are limited to MSM and PWID, demonstrating the paucity of data on the other KP. Also, it highlights the importance of applying a clear VCT-HIV guideline as well as properly training the counselors.

HIV test uptake and related factors amongst heterosexual drug users in Shandong province, China

BACKGROUND

In China, the mode of HIV transmission and the types and routes of drug use have changed in the past decade. HIV testing amongst drug users needs further improvement.

METHODS

Interviewer-administered questionnaires were used for data collection amongst 600 heterosexual drug users from the community and a municipal detention centre, where criminal suspects are supervised. Descriptive statistics, univariate analysis and multilevel logistic regression analysis were used to identify the factors associated with HIV testing amongst heterosexual drug users. All participants were screened HIV and sexually transmitted infections.

RESULTS

Amongst 600 participants, 554 (92.3%) were methamphetamine users, and 155 (25.8%) underwent HIV testing in the past year. Multivariate analysis results revealed that drug users who were single (adjusted odds ratio(AOR) = 1.923, 95% confidence interval(CI) = 1.189-3.109), had less knowledge of HIV (AOR = 1.706, 95% CI = 1.074-2.711), used only one kind of drug (AOR = 2.649, 95% CI = 1.155-6.077), used drug via a non-injection route (AOR = 2.121, 95% CI = 1.103-4.078), did not receive free condoms (AOR = 2.307, 95% CI = 1.129-4.715) and who did not receive free publicity material from health workers in the past year (AOR = 2.828, 95% CI = 1.757-4.552) were less likely to undergo HIV testing. A total of 594 participants underwent HIV and syphilis screening in this survey. Amongst these participants, 2 (0.3%) were HIV antibody positive, and 88 (14.8%) showed positive results in both non-treponemal test (rapid plasma regain test) and treponemal test (Treponema pallidum particle agglutination test) for the first time.

CONCLUSIONS

The rate of HIV test uptake amongst heterosexual drug users in China remains low. Thus, more specific interventions are urgently needed to improve the utilisation of HIV testing amongst heterosexual drug users, particularly amongst non-injection drug users in China.

Preventing blood-borne virus infection in people who inject drugs in the UK: systematic review, stakeholder interviews, psychosocial intervention development and feasibility randomised controlled trial

BACKGROUND

Opioid substitution therapy and needle exchanges have reduced blood-borne viruses (BBVs) among people who inject drugs (PWID). Some PWID continue to share injecting equipment.

OBJECTIVES

To develop an evidence-based psychosocial intervention to reduce BBV risk behaviours and increase transmission knowledge among PWID, and conduct a feasibility trial among PWID comparing the intervention with a control.

DESIGN

A pragmatic, two-armed randomised controlled, open feasibility trial. Service users were Steering Group members and co-developed the intervention. Peer educators co-delivered the intervention in London.

SETTING

NHS or third-sector drug treatment or needle exchanges in Glasgow, London, Wrexham and York, recruiting January and February 2016.

PARTICIPANTS

Current PWID, aged ≥ 18 years.

INTERVENTIONS

A remote, web-based computer randomisation system allocated participants to a three-session, manualised, psychosocial, gender-specific group intervention delivered by trained facilitators and BBV transmission information booklet plus treatment as usual (TAU) (intervention), or information booklet plus TAU (control).

MAIN OUTCOME MEASURES

Recruitment, retention and follow-up rates measured feasibility. Feedback questionnaires, focus groups with participants who attended at least one intervention session and facilitators assessed the intervention's acceptability.

RESULTS

A systematic review of what works to reduce BBV risk behaviours among PWID; in-depth interviews with PWID; and stakeholder and expert consultation informed the intervention. Sessions covered improving injecting technique and good vein care; planning for risky situations; and understanding BBV transmission. Fifty-six per cent (99/176) of eligible PWID were randomised: 52 to the intervention group and 47 to the control group. Only 24% (8/34) of male and 11% (2/18) of female participants attended all three intervention sessions. Overall, 50% (17/34) of men and 33% (6/18) of women randomised to the intervention group and 47% (14/30) of men and 53% (9/17) of women randomised to the control group were followed up 1 month post intervention. Variations were reported by location. The intervention was acceptable to both participants and facilitators. At 1 month post intervention, no increase in injecting in 'risky' sites (e.g. groin, neck) was reported by participants who attended at least one session. PWID who attended at least one session showed a trend towards greater reduction in injecting risk behaviours, a greater increase in withdrawal planning and were more confident about finding a vein. A mean cost of £58.17 per participant was calculated for those attending one session, £148.54 for those attending two sessions and £270.67 for those attending all three sessions, compared with £0.86 in the control group. Treatment costs across the centres vary as a result of the different levels of attendance, as total session costs are divided by attendees to obtain a cost per attendee. The economic analysis suggests that a cost-effectiveness study would be feasible given the response rates and completeness of data. However, we have identified aspects where the service use questionnaire could be abbreviated given the low numbers reported in several care domains. No adverse events were reported.

CONCLUSIONS

As only 19% of participants attended all three intervention sessions and 47% were followed up 1 month post intervention, a future definitive randomised controlled trial of the intervention is not feasible. Exposure to information on improving injecting techniques did not encourage riskier injecting practices or injecting frequency, and benefits were reported among attendees. The intervention has the potential to positively influence BBV prevention. Harm reduction services should ensure that the intervention content is routinely delivered to PWID to improve vein care and prevent BBVs.

FUTURE WORK

The intervention did not meet the complex needs of some PWID, more tailoring may be needed to reach PWID who are more frequent injectors, who are homeless and female.

LIMITATIONS

Intervention delivery proved more feasible in London than other locations. Non-attendance at the York trial site substantially influenced the results.

Integrating HIV and substance use services: a systematic review

INTRODUCTION

Substance use is an important risk factor for HIV, with both concentrated in certain vulnerable and marginalized populations. Although their management differs, there may be opportunities to integrate services for substance use and HIV. In this paper we systematically review evidence from studies that sought to integrate care for people living with HIV and substance use problems.

METHODS

Studies were included if they evaluated service integration for substance use and HIV. We searched multiple databases from inception until October 2015. Articles were screened independently by two reviewers and assessed for risk of bias.

RESULTS AND DISCUSSION

11,057 records were identified, with 7616 after removal of duplicates. After screening titles and abstracts, 51 met the inclusion criteria. Integration models were categorized by location (HIV, substance use and other facilities), level of integration from mirco (integrated care delivered to individuals) to macro (system level integrations) and degree of integration from least (screening and counselling only) to most (care for HIV, substance use and/or other illnesses at the same facility). Most reported descriptive or cohort studies; in four randomized control trials integrated activities improved patient outcomes. There is potential for integrating services at all facility types, including mobile health services. While services offering screening only can achieve synergies, there are benefits from delivering integrated treatment for HIV and substance use, including ease of referral to other mental health and social services.

CONCLUSIONS

Our review used a wide range of databases and conference archives to increase representation of papers from low- and middle-income countries. Limitations include the overrepresentation of studies from the United States, and the descriptive nature of the majority of papers. The evidence reviewed shows that greater integration offers important benefits in both patient and service outcomes but further research and outcome reporting is needed to better understand innovative and holistic care models at the complex intersection of substance use and HIV services.

Psychological interventions for post-traumatic stress disorder in people living with HIV in Resource poor settings: a systematic review

OBJECTIVE

Post-traumatic stress disorder is pervasive in low- and middle-income countries. There is evidence to suggest that post-traumatic stress disorder is more common among people living with HIV than non-infected matched controls. We carried out a systematic review of interventions for adult post-traumatic stress disorder from resource poor settings with a focus on people living with HIV.

METHODS

We included all studies that investigated interventions for adult post-traumatic stress disorder from resource poor settings with a focus on interventions that were either randomised controlled trials or observational cohort studies carried out from 1980 to May 2015.

RESULTS

Of the 25 articles that were identified for full review, two independent reviewers identified seven studies that met our study inclusion criteria. All randomised controlled trials (RCT) (n = 6) used cognitive behavioural therapy-based interventions and focused on people living with HIV in resource poor settings. There was only one study focusing on the use of lay counsellors to address post-traumatic stress disorder but core competencies were not described. There were no intervention studies from Africa, only an observational cohort study from Rwanda.

CONCLUSION

Rigorously evaluated interventions for adult post-traumatic stress disorder in people living with HIV are rare. Most were undertaken in resource poor settings located in high-income countries. There is a need for research on the development and implementation of appropriate interventions for post-traumatic stress disorder in people living with HIV in low- and middle-income countries.

Linkage-to-care Methods and Rates in U.S. Emergency Department-based HIV Testing Programs: A Systematic Literature Review Brief Report

BACKGROUND

An increasing number of U.S. emergency departments (EDs) have implemented ED-based HIV testing programs since the Centers for Disease Control and Prevention issued revised HIV testing recommendations for clinical settings in 2006. In 2010, the National HIV/AIDS Strategy (NHAS) set an linkage-to-care (LTC) rate goal of 85% within 90 days of HIV diagnosis. LTC rates for newly diagnosed HIV-infected patients vary markedly by site, and many are suboptimal. The optimal approach for LTC in the ED setting remains unknown.

OBJECTIVE

The objective was to perform a brief descriptive analysis of the LTC methods practiced in EDs across the United States to determine the overall linkage rate of ED-based HIV testing programs.

METHODS

We conducted a systematic review of literature related to U.S. ED HIV testing in the adult population using PubMed, Embase, Web of Science, Scopus, and Cochrane. There were 333 articles were identified; 31 articles were selected after a multiphasic screening process. We analyzed data from the 31 articles to assess LTC methods and rates. LTC methods that involved physical escort of the newly diagnosed patient to an HIV/infectious disease (ID) clinic or interaction with a specialist health care provider at the ED were operationally defined as "intensive" LTC protocol. "Mixed" LTC protocol was defined as a program that employed intensive linkage only part of the coverage hours. All other forms of linkage was defined as "nonintensive" LTC protocol. An LTC rate of ≥85% was used to identify characteristics of ED-based HIV testing program associated with a higher LTC rate.

RESULTS

There were 37 ED-based HIV testing programs in the 31 articles. The overall LTC rate was 74.4%. Regarding type of protocol, nine (24.3%) employed intensive LTC protocols, 25 (67.6%) nonintensive, two (5.4%) mixed, and one (2.7%) with unclear protocols. LTC rates for programs with intensive and nonintensive LTC protocols were 80.0 and 72.7%, respectively. Four (44.4%) with intensive protocols and nine (36.0%) with the nonintensive protocols had LTC rates > 85%. The linkage staff employed was different between ED programs. Among them, 25 (67.6%) programs used exogenous staff, 10 (27.0%) used the ED staff, and two had no information. All the programs in the nonintensive group utilized drop-in HIV/ID clinic or medical appointments while seven of nine of the programs in the intensive group physically escorted the patients to the initial medical intake appointment. There were no significant differences in characteristics of ED-based HIV testing programs between those with ≥85% LTC rate versus those with <85% within the intensive or nonintensive group.

CONCLUSION

Intensive LTC protocols had a higher LTC rate and a higher proportion of programs that surpassed the >85% NHAS goal compared to nonintensive methods, suggesting that, when possible, ED-based HIV testing programs should adopt intensive LTC strategies to improve LTC outcomes. However, intensive LTC protocols most often required involvement of multidisciplinary non-ED professionals and external research funding. Our findings provide a foundation for developing best practices for ED-based HIV LTC programs.

A Mismatch between High-Risk Behaviors and Screening of Infectious Diseases among People Who Inject Drugs in Dar es Salaam, Tanzania

Background

People who inject drugs are at risk of various infectious diseases. Despite such a risk, evidence is limited which studied the utilization of screening services for common infectious diseases among people who inject drugs in Tanzania. We aimed to examine their high-risk behaviors; utilization of screening services for HIV infection, hepatitis B/C, any other sexually transmitted infection, and tuberculosis; and their associated factors in Dar es Salaam, Tanzania.

Methods

We conducted a baseline cross-sectional study as part of a prospective cohort study of people who inject drugs. We included 578 participants comprising of new enrollees of the integrated methadone-assisted treatment program and those who were selected from the communities but not enrolled in the program. We interviewed new enrollees preceding their enrollment and receipt of services from the program. We measured participants’ high-risk behaviors and their utilization of screening services. We analyzed the data descriptively and used multiple logistic regressions to identify the factors associated with ever being screened for infectious diseases.

Results

Of 578 participants, 14.2% shared injection needles. Of 547 sexually active participants, 37.5% had multiple sexual partners and only 17.4% used a condom. Of all participants, however, only 36.0% had ever been screened for HIV infection, 18.5% for tuberculosis, 11.8% for any other sexually transmitted infection, and 11.6% for hepatitis B/C. They were more likely to have ever been screened for HIV infection if they had education levels above primary education (adjusted odds ratio [AOR]: 2.54, 95% CI: 1.54–4.20), had a history of transactional sex (OR: 2.63, 95% CI: 1.01–6.84), and were new enrollees of the program (AOR: 7.41, 95% CI: 4.41–12.86).

Conclusions

People who inject drugs practice high-risk behaviors but their utilization of screening services for infectious diseases is poor in Dar es Salaam, Tanzania. It is crucial to increase the coverage of screening services for them and strengthen the counseling of safer sexual practices.

Assessment of HIV testing among young methamphetamine users in Muse, Northern Shan State, Myanmar

BACKGROUND

Methamphetamine (MA) use has a strong correlation with risky sexual behaviors, and thus may be triggering the growing HIV epidemic in Myanmar. Although methamphetamine use is a serious public health concern, only a few studies have examined HIV testing among young drug users. This study aimed to examine how predisposing, enabling and need factors affect HIV testing among young MA users.

METHODS

A cross-sectional study was conducted from January to March 2013 in Muse city in the Northern Shan State of Myanmar. Using a respondent-driven sampling method, 776 MA users aged 18-24 years were recruited. The main outcome of interest was whether participants had ever been tested for HIV. Descriptive statistics and multivariate logistic regression were applied in this study.

RESULTS

Approximately 14.7% of young MA users had ever been tested for HIV. Significant positive predictors of HIV testing included predisposing factors such as being a female MA user, having had higher education, and currently living with one's spouse/sexual partner. Significant enabling factors included being employed and having ever visited NGO clinics or met NGO workers. Significant need factors were having ever been diagnosed with an STI and having ever wanted to receive help to stop drug use.

CONCLUSIONS

Predisposing, enabling and need factors were significant contributors affecting uptake of HIV testing among young MA users. Integrating HIV testing into STI treatment programs, alongside general expansion of HIV testing services may be effective in increasing HIV testing uptake among young MA users.

HIV testing and sexual risk reduction counseling in office-based buprenorphine/naloxone treatment

OBJECTIVES

We assessed the feasibility and preliminary efficacy of human immunodeficiency virus (HIV) testing with sexual risk reduction counseling for opioid-dependent patients initiating office-based buprenorphine/naloxone treatment.

METHODS

We conducted a 14-week randomized, controlled trial with 30 patients (original target of 114) assigned to receive buprenorphine/naloxone induction/stabilization and HIV testing with Brief Sexual Risk Management (BSRM) or Enhanced Sexual Risk Management (ESRM). We evaluated process measures and compared outcomes at baseline and during the 3-month follow-up.

RESULTS

Similar proportions of patients receiving BSRM and ESRM underwent HIV testing (93% vs 80%; P = 0.28) and completed counseling sessions (80% vs 67%; P = 0.40). Brief Sexual Risk Management sessions were shorter than ESRM sessions (15.4 vs 23.4 minutes), with comparable manual adherence (P = 0.80). Outcomes did not vary by BSRM versus ESRM.

CONCLUSIONS

Although the recruitment of opioid-dependent patients with sexual risk behaviors is challenging, HIV testing with sexual risk reduction counseling in office-based buprenorphine/naloxone treatment practice is feasible. Interventions to decrease sexual risk behaviors among a segment of this population are necessary.

What are the factors associated with HIV testing among male injecting and non-injecting drug users in Lashio, Myanmar: a cross-sectional study

OBJECTIVES

HIV testing is an effective intervention for reducing HIV risk and providing information on HIV status. However, uptake of HIV testing is a major challenge within the drug-using population due to the stigma and discrimination associated with their illegal drug use behaviours. This study thus aimed to identify factors associated with HIV testing among injecting drug users (IDUs) and non-injecting drug users (NIDUs) in Lashio, Myanmar.

DESIGN

A cross-sectional study was conducted from January 2010 to February 2010.

SETTING

This study was carried out in Lashio city, Northern Shan State, Myanmar.

PARTICIPANTS

In total, 158 male IDUs and 210 male NIDUs were recruited using a respondent-driven sampling method.

PRIMARY OUTCOME MEASURES

Proportion of both drug users who were ever tested for HIV and factors associated with HIV testing.

RESULTS

Approximately 77% of IDUs and 46% of NIDUs were ever tested for HIV. The multivariate analysis revealed that having ever received drug treatment was positively associated with HIV testing among both IDUs (adjusted OR (AOR) 13.07; 95% CI 3.38 to 50.53) and NIDUs (AOR 3.58; 95% CI 1.38 to 9.24). IDUs who were married (AOR 0.24; 95% CI 0.06 to 0.94) and who injected at least twice daily (AOR 0.30; 95% CI 0.09 to 0.97) were less likely to undergo HIV testing. Among NIDUs, those who belonged to Shan (AOR 0.30; 95% CI 0.11 to 0.84) or Kachin (AOR 0.30; 95% CI 0.10 to 0.87) ethnicities were less likely to test for HIV.

CONCLUSIONS

IDUs and NIDUs who have received drug treatment are more likely to test for HIV. Integrating HIV testing into drug treatment programmes alongside general expansion of HIV testing services may be effective in increasing HIV testing uptake among both IDUs and NIDUs in the Northern Shan State of Myanmar.

Qualitative analysis of cocaine and heroin users' main partner sex-risk behavior: is safety in love safety in health?

Background

In 2009, 27% of the 48,100 estimated new cases of HIV were attributed to heterosexual contact with an infected or at-risk person. Sexually active adults are less likely to use condoms in relationships with main partners than with non-regular partners, despite general knowledge that condom use reduces HIV transmission.

Methods

The purpose of this secondary qualitative analysis was to explore and contextualize perceptions of main partnerships, HIV risk, and attitudes toward condom use within main partner relationships among a subsample of intervention-arm cocaine- and/or heroin-using patients enrolled in a negative trial of brief motivational intervention to reduce the incidence of sexually transmitted disease and unsafe sexual behaviors. The open-ended portion of these interview audiotapes consisted of questions about perceptions of risk and attitudes about condom use with main partners. Enrollees were aged 18-54, English or Spanish speaking, and included in this analysis only if they reported having a main partner. We identified codes and elaborated important themes through a standard inductive three step coding process, using HyperRESEARCH™ software.

Results

Among 48 interviewees, 65% were male, half were non-Hispanic white, over 60% were 20-39 years of age, 58% had intravenous drug use (IDU), and 8% were HIV-positive. Participants defined respect, support, trust, and shared child-rearing responsibility as the most valued components of main partner relationships. Condom use was viewed occasionally as a positive means of showing respect with main partners but more often as a sign of disrespect and a barrier to intimacy and affection. Enrollees appraised their partners’ HIV risk in terms of perceptions of physical health, cleanliness, and sexual and HIV testing history. They based decisions regarding condom use mainly on perceived faithfulness, length of involvement, availability of condoms, and pregnancy desirability.

Conclusions

Risk appraisal was commonly based on appearance and subjective factors, and condom use with main sexual partners was described most often as a demonstration of lack of trust and intimacy.
