Mode of HIV exposure and excess burden of neurocognitive impairment in people living with HIV: a protocol for systematic review and meta-analysis of controlled studies.

BACKGROUND: Chronic HIV infection significantly elevates the risk of brain pathology, precipitating neurocognitive impairment (NCI) among people living with HIV (PLWH). The diagnosis of NCI in PLWH hinges on evaluating deviations in neuropsychological test performance in comparison to HIV-seronegative normative controls. However, the adverse psychosocial conditions experienced by PLWH can also result in reduced test performance, potentially confounding the accurate NCI attribution to HIV infection. This planned systematic review aims to investigate potential disparities in the excess burden of NCI among PLWH in two groups of studies: (a) studies enrolling controls who shared a similar mode of HIV exposure (MoHE) with the PLWH participants (MoHE-adjusted) and (b) studies enrolling normative controls or controls without undefined MoHE (MoHE-naive). METHODS: We will systematically search five electronic databases (MEDLINE, Embase, PsycINFO, Web of Science, ProQuest) and registries (OpenGrey, ClinicalTrials.gov, ISRCTN registry). Studies reporting NCI in PLWH and HIV-seronegative controls with cross-sectional or baseline measurements, published from January 2007 to September 2023, will be included. To be classified as MoHE adjusted, a study must evidence ≥ 90% enrolment of both PLWH and their seronegative controls from the same MoHE group (e.g. men who have sex with men, people who use drugs or alcohol). Reports of test performance scores will be transformed into NCI proportions using simulated score distributions, applying a global deficit score cut-off ≥ 0.5 to estimate NCI cases. The Newcastle-Ottawa scale adapted to the purpose of the review will be used to appraise study quality. Random-effects meta-analysis will be used to pool the excess burden of NCI in prevalence ratios and test the difference between MoHE-adjusted and MoHE-naive studies. Furthermore, subgroup analyses and meta-regression will be undertaken across categorical study-level covariates (e.g. study locations, NCI diagnostic criteria) and continuous/ordinal covariates (nadir CD4, number of neurocognitive domains assessed), respectively. DISCUSSION: This systematic review will contribute towards a greater appreciation of the unique psychosocial conditions of PLWH that are missing from the current case definition of HIV-associated neurocognitive disorder. The findings will additionally highlight possible disparities in the distribution of the excess burden of NCI by MoHE groups, thereby guiding the prioritization of mitigation efforts.

Motivational Interviewing as an Intervention to Improve Antiretroviral Treatment Initiation among People who Inject Drugs (PWID): A Pilot Study in Jakarta and Bandung, Indonesia.

INTRODUCTION: Progress towards the 95-95-95 target among People Who Inject Drugs (PWID) with Human Immunodeficiency Virus (HIV) infection was considerably low. A behavioral approach, such as motivational interviewing (MI), has been recognized as an effective strategy for improving HIV treatment outcomes among PWID. OBJECTIVE: This study aimed at assessing the impact of MI counselling to improve ARV initiation among HIV-positive PWID. METHODS: A cohort design pilot study was performed, and participants were recruited using a convenience sampling technique. Participants were PWID with HIV who accessed healthcare facilities in two Indonesian cities. Selected participants were assigned to an intervention group and a control group. The intervention group followed MI counselling, while the control group received ART following the standard of care. The participants were assigned to each group based on their preferences. The data was collected between January 2018 and January 2019. RESULTS: In total, 115 PWID with HIV participated in this study in the intervention (n=30) and control (n=85) groups. All but one intervention group's participants started ART, while 68/85 in the control group did so. Receiving MI counselling significantly contributed to ART initiation. In addition, the participants were followed-up until 12 months after ARV initiation. During this period, we found that similar proportions of participants in both groups discontinued the treatment, and only a small number achieved HIV viral suppression. CONCLUSION: The positive effect of MI counselling on ART initiation provides insight into the possibility of its wider implementation. Further studies are needed to gain a deeper understanding of MI counselling and its effect on other outcomes of the HIV treatment cascade.

Improving medical students' attitude toward patients with substance use problems through addiction medicine education.

Background:Patients with addiction often encounter negative attitudes from health care professionals, including medical doctors. Addiction medicine training might improve medical students' attitudes toward patients with addiction problems and change the way they think about addiction. We evaluated the effect of comprehensive addiction medicine training on students' attitudes and illness perceptions and explored which perceptions are most relevant for attitude development. Methods: In a quasi-experimental non-randomized study, fourth-year students (n = 296) participated in either addiction medicine training (intervention) or one of three other blocks (control). We used the Medical Condition Regards Scale to measure attitudes and the Illness Perception Questionnaire Addiction version for perceptions. We analyzed the effect of the intervention using repeated measures MANOVA. The contribution of illness perception to attitude was explored in the intervention group using linear regression analysis. Results: Addiction medicine training improved students' attitudes toward patients with addiction, compared to the control group. After the training, students expressed a less demoralized perception, a stronger perception of a coherent understanding of addiction, addiction as a cyclical condition, and attributed addiction more to psychological factors, compared to the control group. In the intervention group, attitude and emotional representation before training and illness coherence after the training were associated with attitude after the training. Conclusions: Addiction medicine training is effective in improving medical students' attitudes toward patients with addiction and changing their illness perceptions of addiction. The development of an understanding of addiction might be particularly relevant for attitude improvement. These findings underscore the relevance of addiction medicine training as part of medical curricula and argue for including aspects related to attitude development in the curriculum.

Core addiction medicine competencies for doctors: An international consultation on training.

BACKGROUND: Despite the high prevalence of substance use disorders, associated comorbidities, and the evidence base upon which to base clinical practice, most health systems have not invested in standardized training of health care providers in addiction medicine. As a result, people with substance use disorders often receive inadequate care, at the cost of quality of life and enormous direct health care costs and indirect societal costs. Therefore, this study was undertaken to assess the views of international scholars, representing different countries, on the core set of addiction medicine competencies that need to be covered in medical education. METHODS: A total of 13 members of the International Society of 20 Addiction Medicine (ISAM), from 12 different countries (37% response rate), were interviewed over Skype, e-mail survey, or in person at the annual conference. Content analysis was used to analyze interview transcripts, using constant comparison methodology. RESULTS: We identified recommendations related to the core set of the addiction medicine competencies at 3 educational levels: (i) undergraduate, (ii) postgraduate, and (iii) continued medical education (CME). The participants described broad ideas, such as knowledge/skills/attitudes towards addiction to be obtained at undergraduate level, or knowledge of addiction treatment to be acquired at graduate level, as well as specific recommendations, including the need to tailor curriculum to national settings and different specialties. CONCLUSIONS: Although it is unclear whether a global curriculum is needed, a consensus on a core set of principles for progression of knowledge, attitudes, and skills in addiction medicine to be developed at each educational level amongst medical graduates would likely have substantial value.

Good Psychometric Properties of the Addiction Version of the Revised Illness Perception Questionnaire for Health Care Professionals.

BACKGROUND: Addiction, or substance dependence, is nowadays considered a chronic relapsing condition. However, perceptions of addiction vary widely, also among healthcare professionals. Perceptions of addiction are thought to contribute to attitude and stigma towards patients with addiction. However, studies into perceptions of addiction among healthcare professionals are limited and instruments for reliable assessment of their perceptions are lacking. The Illness Perception Questionnaire (IPQ) is widely used to evaluate perceptions of illness. The aim of this study was to evaluate the psychometric properties of the IPQ: factor structure, internal consistency, and discriminant validity, when applied to evaluate healthcare professionals' perceptions of addiction. METHODS: Participants were 1072 healthcare professionals in training and master students from the Netherlands and Indonesia, recruited from various addiction-training programs. The revised version of the IPQ was adapted to measure perceptions of addiction (IPQ-A). Maximum likelihood method was used to explore the best-fit IPQ factor structure. Internal consistency was evaluated for the final factors. The final factor structure was used to assess discriminant validity of the IPQ, by comparing illness perceptions of addiction between 1) medical students from the Netherlands and Indonesia, 2) medical students psychology students and educational science students from the Netherlands, and 3) participants with different training levels: medical students versus medical doctors. RESULTS: Factor analysis revealed an eight-factor structure for the perception subscale (demoralization, timeline chronic, consequences, personal control, treatment control, illness coherence, timeline cyclical emotional representations) and a four-factor structure for the attribution subscale (psychological attributions, risk factors, smoking/alcohol, overwork). Internal reliability was acceptable to good. The IPQ-A was able to detect differences in perceptions between healthcare professionals from different cultural and educational background and level of training. CONCLUSIONS: The IPQ-A is a valid and reliable instrument to assess healthcare professionals' perceptions of addiction.

Effectiveness and Organization of Addiction Medicine Training Across the Globe.

BACKGROUND: Over the past decade, addiction medicine training curricula have been developed to prepare physicians to work with substance use disorder patients. This review paper aimed at (1) summarizing scientific publications that outline the content of addiction medicine curricula and (2) evaluating the evidence for efficacy for training in addiction medicine. METHODS: We carried out a literature search on articles about addiction medicine training initiatives across the world, using PubMed, PsychINFO and EMBASE with the following search terms 'substance abuse, addiction medicine, education and training.' RESULTS: We found 29 articles on addiction medicine curricula at various academic levels. Nine studies reported on the need for addiction medicine training, 9 described addiction medicine curricula at various academic levels, and 11 described efficacy on addiction medicine curricula. CONCLUSIONS: Several key competences in addiction medicine were identified. Efficacy studies show that even short addiction medicine training programs can be effective in improving knowledge, skills and attitudes related to addiction medicine. A more uniform approach to addiction medicine training in terms of content and accreditation is discussed.
