Gender Differences in the Utility of the Alcohol Use Disorder Identification Test in Screening for Alcohol Use Disorder Among HIV Test Seekers in South Africa

SMSs as an alternative to provider-delivered care for unhealthy alcohol use: study protocol for Leseli, an open-label randomised controlled trial of mhGAP-Remote vs mhGAP-Standard in Lesotho

BACKGROUND

The World Health Organization's (WHO) Mental Health Gap Action Programme (mhGAP) is a validated intervention that can be provided by non-specialised healthcare workers to individuals with unhealthy alcohol use. However, it typically requires several in-person sessions at a health facility, which may limit its feasibility and effectiveness in remote settings. This trial compares mhGAP-Standard, a 4 to 6 in-person session intervention, to mhGAP-Remote, a 1 in-person session intervention followed by 8 week of short message service (SMS) in Lesotho. We hypothesise that mhGAP-Remote is superior to mhGAP-Standard in reducing alcohol use (as detailed by the primary and secondary outcomes below).

METHODS

This is a two-arm randomised open-label multicentre superiority trial. Participants allocated to mhGAP-Standard receive 4 in-person sessions using motivational interviewing, identifying triggers, and alternative behaviours, with the option of two additional booster sessions. Participants in the mhGAP-Remote arm receive 1 in-person session covering the same content, followed by standardised SMSs over 8 weeks that reinforce intervention content. Non-specialist providers deliver the intervention and receive weekly supervision. Adults (Nplanned = 248) attending participating health facilities for any reason and who meet criteria for unhealthy alcohol use based on the Alcohol Use Disorders Identification Test ([AUDIT] score ≥ 6 for women, ≥ 8 for men) are individually randomised to the two arms (1:1 allocation, stratified by participant sex and age (≥ 50 vs < 50 years old). Follow-up assessments occur at 8, 20, and 32 weeks post-randomisation. The primary outcome is change in self-reported alcohol use (continuous AUDIT score), from baseline to 8 weeks follow-up. Change in the AUDIT from baseline to 20 and 32 weeks follow-up is a secondary outcome. Change in the biomarker phosphatidylethanol (secondary), liver enzyme values in serum (exploratory), and HIV viral load (for people with HIV only; exploratory) are also evaluated from baseline throughout the entire follow-up period. A linear regression model will be conducted for the primary analysis, adjusted for the stratification factors. Three a priori sensitivity analyses for the primary outcome are planned based on per protocol treatment attendance, recovery from unhealthy alcohol use, and clinically significant and reliable change.

DISCUSSION

This trial will provide insight into feasibility and effectiveness of a shortened and primarily SMS supported version of mhGAP, which is especially relevant for settings where regular clinic attendance is a major barrier.

Utility of the Alcohol Use Disorder Inventory Test in determining caseness for alcohol use disorder among persons receiving antiretroviral therapy

We sought to determine the utility of the Alcohol Use Disorder Identification Test (AUDIT) in screening for alcohol use disorder (AUD) among 688 users of antiretroviral therapy (ART). We used the receiver operating characteristic (ROC) curve analysis to assess whether the AUDIT reliably detected AUD against the Structured Clinical Interview for the DSM (SCID). Of the samples, 22.09% (CI: 19.05% to 25.38%) of participants met the diagnostic criteria for AUD. Among men (n = 135) and women (n = 553), the prevalence estimates were 31.9% and 19.7%, respectively. For men, a cut-off score of 6 predicted AUD with 88.36% (95%CI: 74.92-96.11) sensitivity and 88.04% (95%CI: 79.61-93.88) specificity. For women, a cut-off score of 4 on the AUDIT yielded an optimal sensitivity of 92.66% (95% CI: 86.05%-96.78%) and a specificity of 93.24% (95% CI: 90.49-95.40%). For men, the AUDIT yielded a positive predictive value (PPV) of 75.55% (95% CI: 66.26%-85.87%) and a negative predictive value (NPV) of 91.49% (95% CI: 87.63-97.37%); for women the PPV and NPV were 77.09% (70.34%-82.68%) and 98.11% (96.37%-99.02%), respectively. The instrument's good sensitivity and specificity indicate it is likely to be useful for screening and referral of ART users who are probably cases of AUD.

Does This Patient Have Alcohol Use Disorder?: The Rational Clinical Examination Systematic Review

Importance

The accuracy of screening tests for alcohol use disorder (defined as a problematic pattern of alcohol use leading to clinically significant impairment or distress) requires reassessment to align with the latest definition in the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) (DSM-5).

Objective

To assess the diagnostic accuracy of screening tools in identifying individuals with alcohol use disorder as defined in the DSM-5.

Data Sources and Study Selection

The databases of MEDLINE and Embase were searched (January 2013-February 2023) for original studies on the diagnostic accuracy of brief screening tools to identify alcohol use disorder according to the DSM-5 definition. Because diagnosis of alcohol use disorder does not include excessive alcohol use as a criterion, studies of screening tools that identify excessive or high-risk drinking among younger (aged 9-18 years), older (aged ≥65 years), and pregnant persons also were retained.

Data Extraction and Synthesis

Sensitivity, specificity, and likelihood ratios (LRs) were calculated. When appropriate, a meta-analysis was performed to calculate a summary LR.

Results

Of 4303 identified studies, 35 were retained (N = 79 633). There were 11 691 individuals with alcohol use disorder or a history of excessive drinking. Across all age categories, a score of 8 or greater on the Alcohol Use Disorders Identification Test (AUDIT) increased the likelihood of alcohol use disorder (LR, 6.5 [95% CI, 3.9-11]). A positive screening result using AUDIT identified alcohol use disorder better among females (LR, 6.9 [95% CI, 3.9-12]) than among males (LR, 3.8 [95% CI, 2.6-5.5]) (P = .003). An AUDIT score of less than 8 reduced the likelihood of alcohol use disorder similarly for both males and females (LR, 0.33 [95% CI, 0.20-0.52]). The abbreviated AUDIT-Consumption (AUDIT-C) has sex-specific cutoff scores of 4 or greater for males and 3 or greater for females, but was less useful for identifying alcohol use disorder (males: LR, 1.8 [95% CI, 1.5-2.2]; females: LR, 2.0 [95% CI, 1.8-2.3]). The AUDIT-C appeared useful for identifying measures of excessive alcohol use in younger people (aged 9-18 years) and in those older than 60 years of age. For those younger than 18 years of age, the National Institute on Alcohol Abuse and Alcoholism age-specific drinking thresholds were helpful for assessing the likelihood of alcohol use disorder at the lowest risk threshold (LR, 0.15 [95% CI, 0.11-0.21]), at the moderate risk threshold (LR, 3.4 [95% CI, 2.8-4.1]), and at the highest risk threshold (LR, 15 [95% CI, 12-19]). Among persons who were pregnant and screened within 48 hours after delivery, an AUDIT score of 4 or greater identified those more likely to have alcohol use disorder (LR, 6.4 [95% CI, 5.1-8.0]), whereas scores of less than 2 for the Tolerance, Worried, Eye-Opener, Amnesia and Cut-Down screening tool and the Tolerance, Annoyed, Cut-Down and Eye-Opener screening tool identified alcohol use disorder similarly (LR, 0.05 [95% CI, 0.01-0.20]).

Conclusions and Relevance

The AUDIT screening tool is useful to identify alcohol use disorder in adults and in individuals within 48 hours postpartum. The National Institute on Alcohol Abuse and Alcoholism youth screening tool is helpful to identify children and adolescents with alcohol use disorder. The AUDIT-C appears useful for identifying various measures of excessive alcohol use in young people and in older adults.

Identifying cases of common mental disorders in the context of HIV care in low and middle income countries

One of the key behavioural factors inhibiting adherence to antiretroviral therapy (ART) is the presence of common mental disorders (CMDs). Correct identification of CMDs can facilitate referral for treatment, the amelioration of symptoms, and consequently improved adherence to ART. To save time and resources, screening is an alternative to conducting diagnostic interviews in case identification. However, an elevated score on a screening instrument does not indicate caseness for a mental health condition, given poor sensitivity and low positive predictive values of many screeners. A large number of false positives means that many people would be incorrectly identified as having a mental health condition and inappropriately referred for treatment. A large number of false negatives means that people who actually require treatment will not be identified as such and may thus go untreated. Thus it is recommended that public health services in low resource countries consider a two-stage approach to screening. When implementing routine screening, only those persons who screen above a commonly used cut-point would undergo a diagnostic interview to determine the presence of a common mental disorder. True cases may then be referred for treatment where these are available, such as anti-depressive medication or psychological treatment.

Substance use and HIV: some considerations in a global context

This brief report calls attention to the relationship between substance use and HIV from a global perspective. The epidemiology of substance use disorders among persons living with HIV and AIDS (PLWHA) is discussed along with specific caveats in the assessment of these disorders. Important macro-interventions include needle and syringe exchange programs (NSEP) and medication assisted therapy (MAT). Yet, structural interventions such as social welfare, child protection and support services for survivors of violence and abuse are necessary to reduce HIV incidence and enhance engagement in care among those living with HIV. To this extent health systems strengthening is necessary, as is integrating services provided by health and social development departments.

Hazardous alcohol use and HIV indicators in six African countries: results from the Population-based HIV Impact Assessments, 2015-2017

INTRODUCTION

Hazardous alcohol use (HAU), defined as a pattern of alcohol consumption that increases the risk of harmful consequences for the user or others, is associated with an elevated risk of human immunodeficiency virus (HIV) infection and poor health outcomes. We describe the association between people living with HIV (PLHIV) who report HAU and key HIV indicators. Gaps in current literature in estimating HAU on HIV outcomes at the regional level of Eastern and Southern Africa still exist and our analysis aims to address this issue.

METHODS

We used weighted pooled data (2015-2017) from the nationally representative Population-based HIV Impact Assessments among adults who provided written consent aged 18-59 years from Eswatini, Malawi, Namibia, Tanzania, Zambia and Zimbabwe. We estimated differences in the prevalence of HIV infection and The Joint United Nations Programme on HIV and AIDS (UNAIDS) 90-90-90 indicators between PLHIV by HAU status using log-binomial regression, stratified by sex. HAU was determined using the Alcohol Use Identification Test-Consumption.

RESULTS

Among the 9755 women and 4444 men who tested HIV positive, 6.6% of women and 21.8% of men engaged in HAU. Women who reported HAU were more likely to be HIV positive (adjusted prevalence ratio [aPR] = 1.31, 95% CI: 1.18-1.46) compared to those who did not report HAU. For the UNAIDS 90-90-90 targets, women who engaged in HAU were more likely to be unaware of their HIV-positive status (aPR = 1.22, 95% CI: 1.01-1.47) and not on antiretroviral therapy (ART) (aPR = 1.73, 95% CI: 1.26-2.37). Men who engaged in HAU were more likely to be unaware of their HIV-positive status (aPR = 1.56, 95% CI 1.39-1.76) and not on ART (aPR = 1.72, 95% CI: 1.30-2.29). No difference in viral load suppression, defined as <1000 copies/ml of HIV RNA, was seen by sex.

CONCLUSIONS

PLHIV who engage in HAU were more likely to have suboptimal outcomes along the HIV care continuum when compared to those who did not engage in HAU. Targeted interventions, such as alcohol screening for HAU in HIV testing and treatment settings and HIV prevention efforts in alcohol-based venues, may help countries reach HIV epidemic control by 2030.
