RESUMO
BACKGROUND: Qualitative methods are incredibly beneficial to the dissemination and implementation of new digital health interventions; however, these methods can be time intensive and slow down dissemination when timely knowledge from the data sources is needed in ever-changing health systems. Recent advancements in generative artificial intelligence (GenAI) and their underlying large language models (LLMs) may provide a promising opportunity to expedite the qualitative analysis of textual data, but their efficacy and reliability remain unknown. OBJECTIVE: The primary objectives of our study were to evaluate the consistency in themes, reliability of coding, and time needed for inductive and deductive thematic analyses between GenAI (ie, ChatGPT and Bard) and human coders. METHODS: The qualitative data for this study consisted of 40 brief SMS text message reminder prompts used in a digital health intervention for promoting antiretroviral medication adherence among people with HIV who use methamphetamine. Inductive and deductive thematic analyses of these SMS text messages were conducted by 2 independent teams of human coders. An independent human analyst conducted analyses following both approaches using ChatGPT and Bard. The consistency in themes (or the extent to which the themes were the same) and reliability (or agreement in coding of themes) between methods were compared. RESULTS: The themes generated by GenAI (both ChatGPT and Bard) were consistent with 71% (5/7) of the themes identified by human analysts following inductive thematic analysis. The consistency in themes was lower between humans and GenAI following a deductive thematic analysis procedure (ChatGPT: 6/12, 50%; Bard: 7/12, 58%). The percentage agreement (or intercoder reliability) for these congruent themes between human coders and GenAI ranged from fair to moderate (ChatGPT, inductive: 31/66, 47%; ChatGPT, deductive: 22/59, 37%; Bard, inductive: 20/54, 37%; Bard, deductive: 21/58, 36%). In general, ChatGPT and Bard performed similarly to each other across both types of qualitative analyses in terms of consistency of themes (inductive: 6/6, 100%; deductive: 5/6, 83%) and reliability of coding (inductive: 23/62, 37%; deductive: 22/47, 47%). On average, GenAI required significantly less overall time than human coders when conducting qualitative analysis (20, SD 3.5 min vs 567, SD 106.5 min). CONCLUSIONS: The promising consistency in the themes generated by human coders and GenAI suggests that these technologies hold promise in reducing the resource intensiveness of qualitative thematic analysis; however, the relatively lower reliability in coding between them suggests that hybrid approaches are necessary. Human coders appeared to be better than GenAI at identifying nuanced and interpretative themes. Future studies should consider how these powerful technologies can be best used in collaboration with human coders to improve the efficiency of qualitative research in hybrid approaches while also mitigating potential ethical risks that they may pose.
RESUMO
During the COVID-19 pandemic, pre-exposure prophylaxis (PrEP) access and adherence decreased nationwide. This study examined pandemic-related disruptions to PrEP access and adherence among clients of a health center (Center) in Los Angeles, California. Clients (n = 25) and Center personnel (n = 11) completed qualitative interviews from March to July 2021. Although the Center provided options for remote PrEP care (i.e., telehealth, STI self-testing kits, and prescription delivery), clients experienced difficulty navigating services or lacked equipment for telehealth. More than half (n = 13) of clients discontinued PrEP during COVID-19 due to decreased sexual partners, relocation, or insurance status changes. Among those who continued PrEP, the majority reported no change in adherence, while a minority reported worsening adherence due to distractions/forgetting, prescription refill issues, lack of insurance coverage, and fear of completing in-person visits. Findings highlight the challenges of navigating PrEP services during COVID-19 and suggest PrEP services enhancement to adapt to crisis events.

BACKGROUND: Due to the persistence of COVID-19, it remains important to measure and examine potential barriers to COVID-19 prevention and treatment to avert additional loss of life, particularly among stigmatized populations, such as people who inject drugs (PWID), who are at high risk for contracting and spreading SARS-CoV-2. We assessed the psychometrics of a novel COVID-19 response-related discrimination scale among PWID, and characterized associations between COVID-19 response-related discrimination, resilience to adversity, and endorsement of COVID-19 disinformation. METHODS: We assessed internal reliability, structural validity and construct validity of a 4-item COVID-19 response-related discrimination scale among PWID living in San Diego County, completing interviewer-administered surveys between October 2020 and September 2021. Using negative binomial regression, we assessed the relationship between COVID-19 response-related discrimination and disinformation and the potential moderating role of resilience. RESULTS: Of 381 PWID, mean age was 42.6 years and the majority were male (75.6 %) and Hispanic (61.9 %). The COVID-19 response-related discrimination scale had modest reliability (α = 0.66, ω = 0.66) as a single construct with acceptable construct validity (all p ≤ 0.05). Among 216 PWID who completed supplemental surveys, a significant association between COVID-19 response-related discrimination and COVID-19 disinformation was observed, which was moderated by resilience (p = 0.044). Specifically, among PWID with high levels of resilience, endorsement of COVID-19 disinformation significantly increased as exposure to COVID-19 response-related discrimination increased (p = 0.011). CONCLUSIONS: These findings suggest that intervening on COVID-19 response-related discrimination may offset the negative outcomes associated with COVID-19 disinformation.

Black/African American communities continue to be disproportionately impacted by HIV with Black people with HIV (PWH) exhibiting poorer outcomes along the HIV treatment cascade. Psychosocial burden may, in part, explain these health disparities among PWH. We implemented a culturally adapted intervention [individualized Texting for Adherence Building (iTAB)] to improve ART adherence among 89 Black PWH in San Diego, CA. We aimed to (1) characterize psychosocial risk factors (depression, negative life events, discrimination, medical mistrust) hypothesized to be barriers to HIV outcomes among Black PWH and (2) determine if these factors influence intervention engagement, HIV outcomes, and self-reported physical and mental health. We identified three levels of psychosocial burden (low, moderate, high) through hierarchical cluster analysis. Participants in the high burden cluster (n = 25) experienced the highest levels of depression, negative life events, and discrimination, in addition to the poorest intervention outcomes, HIV outcomes, and physical and mental health compared to low and moderate burden clusters. Participants in the low (n = 29) burden cluster had less medical mistrust than the moderate (n = 34) and high burden clusters, but low and moderate clusters did not differ on any outcomes. Overall, self-reported ART adherence was 83%, which is above estimates of ART adherence in the Western region of the United States. The iTAB intervention shows promise in improving HIV-related outcomes among Black PWH with low to moderate psychosocial burden; however, additional supports may need to be identified for those with high psychosocial burden.

OBJECTIVE: Rates of hazardous alcohol consumption and co-occurring posttraumatic stress disorder (PTSD) are high among returning combat veterans and may adversely affect satisfaction with life (SWL). Improving life satisfaction represents a potential secondary outcome of web-based interventions for alcohol use and PTSD. Understanding the relationship between intervention targets and SWL may help inform future interventions and provide clarity regarding how improvements are manifesting. We examined returning veterans enrolled in VetChange, an evidence-based web intervention for co-occurring alcohol use and PTSD, to determine changes in SWL over time and as a function of changes in alcohol consumption and PTSD symptoms. METHOD: Participants included 222 returning veterans who reported hazardous drinking. Veterans engaged in a nationwide implementation of VetChange and completed measures of average weekly drinks (AWD), PTSD symptoms, and SWL at baseline, 1, 3, and 6 months. We investigated the effects of changes in PTSD and AWD between baseline and 1 month on SWL over 6 months using linear mixed-effects modeling. RESULTS: Across all veterans, SWL increased by 19% over 6 months. AWD and PTSD decreased between baseline and 1 month, but only change in PTSD predicted changes in SWL over the 6-month interval. CONCLUSIONS: Reductions in PTSD symptoms within the first month of intervention use, and not reductions in drinking, predicted increased SWL over 6 months. SWL is an important marker for recovery and related quality of life, and an important assessment and intervention target of web-based interventions. Interventions may also target SWL, as improvements in SWL promote future recovery and sustained improvement. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
RESUMO
Antiretroviral therapy (ART) and pre-exposure prophylaxis (PrEP) are key strategies in ending the HIV epidemic. However, poor adherence to daily ART and PrEP increases the risk of HIV transmission and acquisition. Long-acting ART and PrEP formulations attempt to improve adherence through providing long-lasting forms of the medication delivered through different routes of administration: oral (potentially monthly), injection (1-6 months), and subdermal implant (up to annually). This study explored patient and physician preferences for long-acting ART and PrEP as well as adherence support strategies. Adult patients (n = 42) with experience taking ART or PrEP participated in individual interviews or focus groups. Physicians (n = 13) currently prescribing ART and/or PrEP completed an online questionnaire. Rapid qualitative analysis systematically synthesized qualitative data, and descriptive statistics examined survey responses. Patients supported improved adherence as a top potential advantage of long-acting ART and PrEP, and reduced internal stigma as a strong benefit specific to long-acting ART. Annual coverage offered through subdermal implants had strong appeal; however, oral was the preferred modality for long-acting ART and PrEP. Patients preferred injectable ART and PrEP if concurrently receiving hormone therapy injections. Side effects, medication cost, and treatment accessibility were potential barriers. Patients preferred calendar tracking and text messages/phone reminders for adherence supports. Physicians reported that they would reduce clinic visits and HIV testing for all patients on long-acting PrEP, except men who have sex with men who would continue to complete HIV testing every 3 months. Physicians were mixed on whether they believed long-acting ART and PrEP would improve patient adherence. Overall, findings demonstrate the potential benefits of long-acting ART and PrEP, while highlighting the need to obtain additional information to address treatment concerns.

BACKGROUND: In Kyrgyzstan and other Eastern European and Central Asian countries, injection drug use and HIV-related intersectional stigma undermines HIV prevention efforts, fueling a rapidly expanding HIV epidemic. The Kyrgyzstan InterSectional Stigma (KISS) Injection Drug Use Cohort is the first study designed to assess the impact of drug use, methadone maintenance treatment (MMT) and HIV stigma experiences among people who inject drugs (PWID) on HIV prevention service utilization. METHODS: Adult PWID were recruited from Bishkek city and the surrounding rural Chuy Oblast region in northern Kyrgyzstan via modified time location sampling and snowball sampling. All participants completed a baseline rapid HIV test and interviewer-administered survey. A subsample of participants were prospectively followed for three months and surveyed to establish retention rates for future work in the region. Internal reliability of three parallel stigma measures (drug use, MMT, HIV) was evaluated. Descriptive statistics characterize baseline experiences across these three stigma types and HIV prevention service utilization, and assess differences in these experiences by urbanicity. RESULTS: The KISS cohort (N = 279, 50.5% Bishkek, 49.5% Chuy Oblast) was mostly male (75.3%), ethnically Russian (53.8%), median age was 40 years old (IQR 35-46). Of the 204 eligible participants, 84.9% were surveyed at month 3. At baseline, 23.6% had a seropositive rapid HIV test. HIV prevention service utilization did not differ by urbanicity. Overall, we found 65.9% ever utilized syringe service programs in the past 6 months, 8.2% were utilizing MMT, and 60.8% met HIV testing guidelines. No participants reported PrEP use, but 18.5% had heard of PrEP. On average participants reported moderate levels of drug use (mean [M] = 3.25; α = 0.80), MMT (M = 3.24; α = 0.80), and HIV stigma (M = 2.94; α = 0.80). Anticipated drug use stigma from healthcare workers and internalized drug use stigma were significantly higher among PWID from Bishkek (p < 0.05), while internalized HIV stigma among PWID living with HIV was significantly greater among PWID from Chuy Oblast (p = 0.03). CONCLUSION: The KISS cohort documents moderate levels of HIV-related intersectional stigma and suboptimal engagement in HIV prevention services among PWID in Kyrgyzstan. Future work will aim identify priority stigma reduction intervention targets to optimize HIV prevention efforts in the region.

BACKGROUND: People who inject drugs (PWID) are vulnerable to SARS-CoV-2 infection. We examined correlates of COVID-19 testing among PWID in the U.S.-Mexico border region and described encounters with services representing potential opportunities (i.e., 'touchpoints') where COVID-19 testing could have been offered. METHODS: Between October, 2020 and September, 2021, participants aged ≥18 years from San Diego, California, USA and Tijuana, Baja California, Mexico who injected drugs within the last month completed surveys and SARS-CoV-2, HIV, and HCV serologic testing. Logistic regression identified factors associated with COVID-19 testing including potential touchpoints, comorbidities and COVID-19 related misinformation and disinformation. RESULTS: Of 583 PWID, 30.5% previously had a COVID-19 test. Of 172 PWID who tested SARS-CoV-2 seropositive (30.1%), 50.3% encountered at least one touchpoint where COVID-19 testing could have been offered within the prior six months. Factors independently associated with at least two fold higher odds of COVID-19 testing were living in San Diego, recent incarceration, receiving substance use treatment, and experiencing ≥1 chronic health condition. Homelessness, having received ≥1 dose of COVID-19 vaccine, and having a HIV or HCV test since the COVID-19 epidemic began were also independently associated with having had a prior COVID-19 test. CONCLUSION: We identified several factors independently associated with COVID-19 testing and multiple touchpoints where COVID-19 testing could be scaled up for PWID, such as SUD treatment programs and syringe service programs. Integrated health services are needed to improve access to rapid, free COVID-19 testing in this vulnerable population.

People who inject drugs (PWID) are vulnerable to SARS-CoV-2 infection. We examined correlates of COVID-19 testing among PWID in the U.S.-Mexico border region and described encounters with services or venues representing potential opportunities (i.e., 'touchpoints') where COVID-19 testing could have been offered. Between October, 2020 and September, 2021, participants aged ≥18 years from San Diego, California, USA and Tijuana, Baja California, Mexico who injected drugs within the last month completed surveys and SARS-CoV-2, HIV, and HCV serologic testing. Logistic regression was used to identify factors associated with COVID-19 testing prior to enrollment. Of 583 PWID, 30.5% previously had a COVID-19 test. Of 172 PWID who tested SARS-CoV-2 seropositive in our study (30.1%), 50.3% encountered at least one touchpoint within the prior six months where COVID-19 testing could have been offered. Factors independently associated with at least two fold higher odds of COVID-19 testing were living in San Diego (versus Tijuana), having recently been incarcerated or attending substance use disorder (SUD) treatment and having at least one chronic health condition. In addition, recent homelessness, having had at least one COVID-19 vaccine dose and having been tested for HIV or HCV since the pandemic began were independently associated with COVID-19 testing. We identified several factors independently associated with COVID-19 testing and multiple touchpoints where COVID-19 testing could be scaled up for PWID, such as SUD treatment programs and syringe service programs. Integrated health services are needed to improve access to rapid, free COVID-19 testing in this vulnerable population.
RESUMO
The objective of this study was to quantify incidence and determine predictors of Gram-negative bacilli (GNB) in people who inject drugs (PWID) with injection-drug use (IDU)-related infections. The investigation was a retrospective cohort of hospitalized PWID from January 2017 to December 2019. Inclusion criteria were age of ≥18 years, active IDU, treated IDU-attributable infection, and organism growth from microbiology cultures. Infection types included infective endocarditis (IE), acute bacterial skin/skin structure infection (ABSSSI), osteoarticular infection (OAI), and other bloodstream infections (BSI). Primary outcome was GNB identification from microbiologic culture; descriptive statistics were used to describe the cohort. Multivariable regression was used to identify variables associated with GNB infection. A total of 230 PWID were included, 65 (28%) with GNB infections and 165 (72%) with Gram-positive infections. The median (interquartile range [IQR]) population age was 38 (31 to 45) years. Most patients were women (56%); 37% had no insurance. Infection types were as follows: IE, 41%; ABSSSI, 37%; OAI, 20%; and other BSI, 2%. A total of 278 organisms were isolated from 230 patients. The most common organisms were methicillin-resistant Staphylococcus aureus (43%), Streptococcus spp. (19%), methicillin-susceptible S. aureus (17%), and Serratia marcescens (8%); 10% of infections were mixed GNB and Gram-positive infections. A total of 80% of patients received empirical Pseudomonas aeruginosa coverage; only 7% had P. aeruginosa infections. In multivariable regression, age of >50 years (adjusted odds ratio [adjOR], 2.9; 95% confidence interval [CI], 1.2 to 7.2), prior hospitalization within 90 days (adjOR, 2.2; 95% CI, 1.2 to 4.3), and OAI (adjOR, 3.2; 95% CI, 1.5 to 6.6) were associated with GNB infection. GNB in PWID with IDU-attributable infections were more frequently observed in recently hospitalized, older patients with OAI. The majority of patients received empirical antipseudomonal antibiotic coverage, but P. aeruginosa was infrequent. PWID are a potential population to target improved empirical antibiotic use.

Data supporting oral step-down therapy in methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infection (BSI) are sparse; linezolid offers potential in this setting. This study aimed to determine the effectiveness and safety of oral step-down linezolid compared with standard parenteral therapy (SPT) in MRSA-BSI. This was a retrospective cohort performed in adults receiving step-down/outpatient linezolid or SPT (vancomycin, daptomycin) for MRSA-BSI from 2011-2019. Primary outcome was 90-day infection-related re-admission (IRR) from clinical worsening/relapse or infection recurrence. 215 patients included (54 linezolid, 161 SPT). Infection sources were skin (34%), bone/joint (15%), endocarditis (13%), other (32%), multiple (6%). Patients receiving SPT more commonly had complicated bacteraemia (72% vs. 41%; P < 0.0001) and metastatic foci (45% vs. 20%; P = 0.001). 90-day IRR occurred in 17% and 26% of linezolid and SPT groups, respectively (P = 0.159). When accounting for disease severity, linezolid use was not independently associated with 90-day IRR (adjOR, 1.0, 95% CI 0.24-4.3; P = 0.986). There were no differences in all-cause 90-day mortality (4% vs. 6%, P = 0.487) or overall incidence of drug-related adverse events (AEs) (17% vs. 16%; P = 0.843) between the groups. More patients in the SPT group developed an AE requiring re-hospitalisation (12% vs. 2%; P = 0.024), most commonly line-related complications. Oral step-down linezolid demonstrated similar clinical and safety outcomes compared with SPT for MRSA-BSI, except linezolid was associated with fewer AEs requiring re-hospitalisation. Additional research is needed exploring step-down linezolid in MRSA-BSI, particularly in patients requiring shorter durations of outpatient therapy.

OBJECTIVE: To assess the efficacy and safety of dalbavancin compared to standard-of-care (SOC) or vancomycin and daptomycin in invasive infections due to suspected or confirmed Gram-positive organisms. METHODS: Retrospective cohort of adults who received dalbavancin or SOC on discharge or as an outpatient from 12/2016 to 11/2019. Indications were osteoarticular infection (OAI), infective endocarditis (IE), or other bloodstream infection (BSI). Primary endpoint was 90-day infection-related readmission (IRR); secondary endpoints included time-to-IRR, frequency of adverse drug events (ADEs), and all-cause readmission and mortality. RESULTS: 215 patients were included: 70 (33%) receiving dalbavancin, and 145 (67%) receiving SOC. Indications were OAI (47%), IE (27%), and other BSI (26%). OAI was more common in patients on dalbavancin compared with those receiving SOC (70% vs. 37%, P<0.001). Dalbavancin patients had shorter median (interquartile range [IQR]) length of stay (LOS) prior to drug initiation compared with those receiving SOC (10 [7-17] vs. 13 [9-19], P=0.021). IRR incidence was 17% for dalbavancin patients and 28% for SOC patients. Dalbavancin use was independently associated with lower IRR (adjusted odds ratio [adjOR], 0.10; 95% confidence interval [CI], 0.04-0.31). There was longer median (IQR) time-to-IRR in the dalbavancin group (43 [30-87] vs. 23 [11-63] days, P=0.039), but no differences in all-cause readmission or mortality. Treatment-related ADE incidence was 3% and 14% for the dalbavancin and SOC groups, respectively (P=0.013). Infusion reactions (1/2) and catheter-related complications (1/2) were the most common dalbavancin ADEs; catheter-related complications (14/21), nephrotoxicity (3/21), rhabdomyolysis (2/21), and rash (2/21) were the most common SOC ADEs. CONCLUSIONS: Dalbavancin use was associated with lower 90-day IRR, a shorter hospital LOS prior to therapy, and longer time-to-IRR compared with SOC.
