RESUMO

BACKGROUND: Tanzania is a low income, East African country with a severe shortage of human resources for health or health workers. This shortage threatens any gains the country is making in improving maternal health outcomes. This paper describes a partnership between Touch Foundation and NYU Rory Meyers College of Nursing - Global, aimed at improving clinical mentorship and capacity among nurses and midwives at two rural hospitals in the Tanzanian Lake Zone Region. Clinical mentoring capacity building and supportive supervision of staff has been shown to be a facilitator of retaining nurses and would be possible to acquire and implement quickly, even in a context of low resources and limited technology. METHODS: A case study approach structures this program implementation analysis. The NYU Meyers team conducted a 6-day needs assessment at the two selected hospitals. A SWOT analysis was performed to identify needs and potential areas for improvement. After the assessment, a weeklong training, tailored to each hospitals' specific needs, was designed and facilitated by two NYU Meyers nursing and midwifery education specialists. The program was created to build on the clinical skills of expert nurse and midwife clinicians and suggested strategies for incorporating mentoring and preceptorship as a means to enhance clinical safety and promote professional communication, problem solving and crisis management. RESULTS: Nineteen participants from both hospitals attended the training. Fourteen of 19 participants completed a post training, open ended questionnaire for a 74% response rate. Fifty-seven percent of participants were able to demonstrate and provide examples of the concepts of mentorship and supervision 4 and 11 months' post training. Participants indicated that while confidence in skills was not lacking, barriers to quality care lay mostly in understaffing. Implementation also offered multiple insights into contextual factors affecting sustainable program implementation. CONCLUSIONS: Three recommendations from this training include: 1) A pre-program assessment should be conducted to ascertain contextual relevance to curriculum development; 2) flexibility and creativity in teaching methods are essential to engage students; and 3) access to participants a priori to program implementation may facilitate a more tailored approach and lead to greater participant engagement.

RESUMO

We evaluated performance, accuracy, and acceptability parameters of unsupervised oral fluid (OF) HIV self-testing (HIVST) in a general population in western Kenya. In a prospective validation design, we enrolled 240 adults to perform rapid OF HIVST and compared results to staff administered OF and rapid fingerstick tests. All reactive, discrepant, and a proportion of negative results were confirmed with lab ELISA. Twenty participants were video-recorded conducting self-testing. All participants completed a staff administered survey before and after HIVST to assess attitudes towards OF HIVST acceptability. HIV prevalence was 14.6 %. Thirty-six of the 239 HIVSTs were invalid (15.1 %; 95 % CI 11.1-20.1 %), with males twice as likely to have invalid results as females. HIVST sensitivity was 89.7 % (95 % CI 73-98 %) and specificity was 98 % (95 % CI 89-99 %). Although sensitivity was somewhat lower than expected, there is clear interest in, and high acceptability (94 %) of OF HIV self-testing.

RESUMO

BACKGROUND: Human immunodeficiency virus (HIV) disease in the United States disproportionately affects minorities, including Latinos. Barriers including language are associated with lower antiretroviral therapy (ART) adherence seen among Latinos, yet ART and interventions for clinic visit adherence are rarely developed or delivered in Spanish. OBJECTIVE: The aim was to adapt a computer-based counseling tool, demonstrated to reduce HIV-1 viral load and sexual risk transmission in a population of English-speaking adults, for use during routine clinical visits for an HIV-positive Spanish-speaking population (CARE+ Spanish); the Technology Acceptance Model (TAM) was the theoretical framework guiding program development. METHODS: A longitudinal randomized controlled trial was conducted from June 4, 2010 to March 29, 2012. Participants were recruited from a comprehensive HIV treatment center comprising three clinics in New York City. Eligibility criteria were (1) adults (age ≥18 years), (2) Latino birth or ancestry, (3) speaks Spanish (mono- or multilingual), and (4) on antiretrovirals. Linear and generalized mixed linear effects models were used to analyze primary outcomes, which included ART adherence, sexual transmission risk behaviors, and HIV-1 viral loads. Exit interviews were offered to purposively selected intervention participants to explore cultural acceptability of the tool among participants, and focus groups explored the acceptability and system efficiency issues among clinic providers, using the TAM framework. RESULTS: A total of 494 Spanish-speaking HIV clinic attendees were enrolled and randomly assigned to the intervention (arm A: n=253) or risk assessment-only control (arm B, n=241) group and followed up at 3-month intervals for one year. Gender distribution was 296 (68.4%) male, 110 (25.4%) female, and 10 (2.3%) transgender. By study end, 433 of 494 (87.7%) participants were retained. Although intervention participants had reduced viral loads, increased ART adherence and decreased sexual transmission risk behaviors over time, these findings were not statistically significant. We also conducted 61 qualitative exit interviews with participants and two focus groups with a total of 16 providers. CONCLUSIONS: A computer-based counseling tool grounded in the TAM theoretical model and delivered in Spanish was acceptable and feasible to implement in a high-volume HIV clinic setting. It was able to provide evidence-based, linguistically appropriate ART adherence support without requiring additional staff time, bilingual status, or translation services. We found that language preferences and cultural acceptability of a computer-based counseling tool exist on a continuum in our urban Spanish-speaking population. Theoretical frameworks of technology's usefulness for behavioral modification need further exploration in other languages and cultures.

RESUMO

BACKGROUND: Intentional childbearing may place heterosexual couples at risk of HIV infection in resource-limited settings with high HIV prevalence areas where society places great value on having children. OBJECTIVE: To explore cognitive, cultural, and spatial mapping of sexual and reproductive health domains and services in western Kenya among men and women. DESIGN: Community-based formative qualitative study design. SETTING: Five administrative/geographical divisions of Nyando District, western Kenya. SUBJECTS: Adult men 18 years and older and women who were of reproductive-potential ages (15 to 49 years for females) (n=90). RESULTS: Men and women have disparate goals for number of children and engage in gendered patterns of protective method use (contraceptives used by women often in secret, condoms by men but rarely). CONCLUSION: HIV infection was still seen as stigmatizing. These study results are relevant to design of effective integrated delivery for reproductive and HIV services in high-burden sub-Saharan African countries.

RESUMO

BACKGROUND: Clinical risk score tools require validation in diverse settings and populations before they are widely implemented. We aimed to externally validate an HIV risk assessment tool for predicting HIV acquisition among pregnant and postpartum women. In the context of prevention of mother-to-child transmission programs, risk score tools could be used to prioritize retesting efforts and delivery of pre-exposure prophylaxis (PrEP) to pregnant and postpartum women most at risk for HIV acquisition while minimizing unnecessary perinatal exposure. METHODS: Data from women enrolled in a cross-sectional study of programmatic HIV retesting and/or receiving maternal and child health care services at five facilities in Western Kenya were used to validate the predictive ability of a simplified risk score previously developed for pregnant/postpartum women. Incident HIV infections were defined as new HIV diagnoses following confirmed negative or unknown status during pregnancy. Predictive performance was assessed using the area under the receiver operating characteristic curve (AUC) and Brier score. RESULTS: Among 1266 women with 35 incident HIV infections, we found an AUC for predicting HIV acquisition of 0.60 (95% CI, 0.51, 0.69), with a Brier score of 0.27. A risk score >6 was associated with a 2.9-fold increase in the odds of HIV acquisition (95% CI, 1.48, 5.70; p = 0.002) vs scores ≤6. Women with risk scores >6 were 27% (346/1266) of the population but accounted for 52% of HIV acquisitions. Syphilis, age at sexual debut, and unknown partner HIV status were significantly associated with increased risk of HIV in this cohort. CONCLUSION: The simplified risk score performed moderately at predicting risk of HIV acquisition in this population of pregnant and postpartum women and may be useful to guide PrEP use or counseling.

RESUMO

INTRODUCTION: The Data-informed Stepped Care (DiSC) study is a cluster-randomized trial implemented in 24 HIV care clinics in Kenya, aimed at improving retention in care for adolescents and youth living with HIV (AYLHIV). DiSC is a multi-component intervention that assigns AYLHIV to different intensity (steps) of services according to risk. We used the Framework for Reporting Adaptations and Modifications-Expanded (FRAME) to characterize provider-identified adaptations to the implementation of DiSC to optimize uptake and delivery, and determine the influence on implementation outcomes. METHODS: Between May and December 2022, we conducted continuous quality improvement (CQI) meetings with providers to optimize DiSC implementation at 12 intervention sites. The meetings were guided by plan-do-study-act processes to identify challenges during early phase implementation and propose targeted adaptations. Meetings were audio-recorded and analysed using FRAME to categorize the level, context and content of planned adaptations and determine if adaptations were fidelity consistent. Providers completed surveys to quantify perceptions of DiSC acceptability, appropriateness and feasibility. Mixed effects linear regression models were used to evaluate these implementation outcomes over time. RESULTS: Providers participated in eight CQI meetings per facility over a 6-month period. A total of 65 adaptations were included in the analysis. The majority focused on optimizing the integration of DiSC within the clinic (83%, n = 54), and consisted of improving documentation, addressing scheduling challenges and improving clinic workflow. Primary reasons for adaptation were to align delivery with AYLHIV needs and preferences and to increase reach among AYLHIV: with reminder calls to AYLHIV, collaborating with schools to ensure AYLHIV attended clinic appointments and addressing transportation challenges. All adaptations to optimize DiSC implementation were fidelity-consistent. Provider perceptions of implementation were consistently high throughout the process, and on average, slightly improved each month for intervention acceptability (ß = 0.011, 95% CI: 0.002, 0.020, p = 0.016), appropriateness (ß = 0.012, 95% CI: 0.007, 0.027, p<0.001) and feasibility (ß = 0.013, 95% CI: 0.004, 0.022, p = 0.005). CONCLUSIONS: Provider-identified adaptations targeted improved integration into routine clinic practices and aimed to reduce barriers to service access unique to AYLHIV. Characterizing types of adaptations and adaptation rationale may enrich our understanding of the implementation context and improve abilities to tailor implementation strategies when scaling to new settings.

RESUMO

BACKGROUND: People who inject drugs (PWID) are at increased risk of HIV acquisition and often encounter barriers to accessing healthcare services. Uganda has high HIV prevalence among PWID and lacks integrated pre-exposure prophylaxis (PrEP) and harm reduction services. Understanding PWID experiences accessing and using harm reduction services and PrEP will inform strategies to optimize integration that align with PWID needs and priorities. METHODS: Between May 2021 and March 2023, we conducted semi-structured interviews with PWID in Kampala, Uganda. We recruited participants with and without previous experience accessing harm reduction services and/or PrEP using purposive and snowball sampling. Interviews were audio recorded, translated, and transcribed. We used thematic analysis to characterize motivations for uptake of harm reduction and HIV prevention services, and strategies to optimize delivery of needle and syringe programs (NSP), medications for opioid use disorder (MOUD), and PrEP. RESULTS: We conducted interviews with 41 PWID. Most participants were relatively aware of their personal HIV risk and accurately identified situations that increased risk, including sharing needles and engaging in transactional sex. Despite risk awareness, participants described engaging in known HIV risk behaviors to satisfy immediate drug use needs. All reported knowledge of harm reduction services, especially distribution of sterile needles and syringes, and many reported having experience with MOUD. Participants who had accessed MOUD followed two primary trajectories; limited resources and relationships with other PWID caused them to discontinue treatment while desire to regain something they believed was lost to their drug use motivated them to continue. Overall, PrEP knowledge among participants was limited and few reported ever taking PrEP. However, participants supported integrating PrEP into harm reduction service delivery and advocated for changes in how these services are accessed. Stigma experienced in healthcare facilities and challenges acquiring money for transportation presented barriers to accessing current facility-based harm reduction and HIV prevention services. CONCLUSIONS: Meeting the HIV prevention needs of PWID in Uganda will require lowering barriers to access, including integrated delivery of PrEP and harm reduction services and bringing services directly to communities. Additional training in providing patient-centered care for healthcare providers may improve uptake of facility-based services.

RESUMO

BACKGROUND: The COVID-19 pandemic resulted in disruptions to routine HIV services for youth living with HIV (YLH), provoking rapid adaptation to mitigate interruptions in care. The Adolescent Transition to Adult Care for HIV-infected adolescents (ATTACH) study (NCT03574129) was a hybrid I cluster randomized trial testing the effectiveness of a healthcare worker (HCW)-delivered disclosure and transition intervention - the Adolescent Transition Package (ATP). During the pandemic, HCWs leveraged phone delivery of the ATP and were supported to make adaptations. We characterized real-time, provider-driven adaptations made to support phone delivery of the ATP. METHODS: We conducted continuous quality improvement (CQI) meetings with HCWs involved in phone delivery of the ATP at 10 intervention sites. CQI meetings used plan-do-study-act (PDSA) cycles and were audio-recorded. Adaptations were coded by two-independent coders using the Framework for Reporting Adaptations and Modifications to Evidence-based Implementation Strategies (FRAME-IS). Adaptation testing outcomes (adopt, retest, or abandon) and provider experience implementing the adaptations were also recorded. We summarized adaptation characteristics, provider experience, and outcomes. RESULTS: We identified 72 adaptations, 32 were unique. Overall, adaptations included modification to context (53%, n = 38), content (49%, n = 35), and evaluation processes (13%, n = 9). Context adaptations primarily featured changes to personnel, format, and setting, while content and evaluation adaptations were frequently achieved by simple additions, repetition, and tailoring/refining of the phone delivery strategy. Nine adaptations involved abandoning, then returning to phone delivery. HCWs sought to increase reach, improve fidelity, and intervention fit within their context. Most adaptations (96%, n = 69) were perceived to increase the feasibility of phone delivery when compared to before the changes were introduced, and HCWs felt 83% (n = 60) of adaptations made phone delivery easier. Most adaptations were either incorporated into routine workflows (47%) or tested again (47%). CONCLUSION: Adaptation of phone delivery was a feasible and effective way of addressing challenges with continuity of care for YLH during the COVID-19 pandemic. Adaptations were primarily context adaptions. While FRAME-IS was apt for characterizing adaptations, more use cases are needed to explore the range of its utility. TRIAL REGISTRATION: Trial registered on ClinicalTrial.gov as NCT03574129.

RESUMO

INTRODUCTION: Efforts to improve health outcomes among adolescents and young adults living with HIV (ALHs) are hampered by limited adolescent engagement in HIV-related research. We sought to understand the views of adolescents, caregivers and healthcare workers (HCWs) about who should make decisions regarding ALHs' research participation. METHODS: We conducted focus group discussions (FGDs) and in-depth interviews (IDIs) with ALHs (aged 14-24 years), caregivers of ALHs and HCWs from six HIV care clinics in Western Kenya. We used semi-structured guides to explore ALHs' involvement in research decisions. Transcripts were analysed using thematic analysis; perspectives were triangulated between groups. RESULTS: We conducted 24 FGDs and 44 IDIs: 12 FGDs with ALHs, 12 with caregivers, and 44 IDIs with HCWs, involving 216 participants. HCWs often suggested that HIV research decision-making should involve caregivers and ALHs deciding together. In contrast, ALHs and parents generally thought decisions should be made individually, whether by HCWs/research teams (although this is likely ethically problematic), adolescents or caregivers. Caregiver and ALH preferences depended on ALHs' age, with younger ALHs requiring more support. A few caregivers felt that ALHs should consult with the research team/HCWs due to their greater knowledge of clinical care. ALHs emphasised that they should independently decide because they thought they had the right to do so and the capacity to consent. Poor communication and parental non-disclosure of HIV status influenced ALHs' views to exclude caregivers from decision-making. Regarding influences on research decision-making, ALHs were more willing to participate based on perceived contribution to science and less interested in participating in studies with potential risks, including loss of confidentiality. DISCUSSION: While research teams and HCWs felt that adolescents and caregivers should jointly make research decisions, ALHs and caregivers generally felt individuals should make decisions. As ALHs sometimes find caregiver support lacking, improving family dynamics might enhance research engagement.

RESUMO

INTRODUCTION: Engaging adolescents in HIV care and research promotes the development of interventions tailored to their unique needs. Guidelines generally require parental permission for adolescents to receive HIV care/testing or participate in research, with exceptions. Nevertheless, parental permission requirements can restrict adolescent involvement in care and research. To better appreciate prospects for policy reform, we sought to understand the perspectives of stakeholders involved in the development, review and implementation of policies related to adolescents living with HIV. METHODS: Semi-structured individual interviews (IDIs) were conducted from October 2019 to March 2020 with 18 stakeholders with expertise in the (1) development of policy through membership in the Law Society of Kenya or work as a health policy official; (2) review of policy through ethics review committee service; or (3) implementation of policy through involvement in adolescent education. IDIs were conducted in English by Kenyan social scientists, audio-recorded and transcribed verbatim. We used thematic analysis to identify themes around how policies can be reformed to improve adolescent engagement in HIV care and research. RESULTS: Our analysis identified three major themes. First, policies should be flexible rather than setting an age of consent. Stakeholders noted that adolescents' capacity for engagement in HIV care and research depended on context, perceived risks and benefits, and "maturity"-and that age was a poor proxy for the ability to understand. Second, policies should evolve with changing societal views about adolescent autonomy. Participants recognized a generational shift in how adolescents learn and mature, suggesting the need for a more frequent review of HIV care and research guidelines. Third, adults should empower adolescent decision-making. Stakeholders felt that caregivers can gradually involve adolescents in decision-making to equip them to gain ownership over their health and lives, improving their confidence and capacity. CONCLUSIONS: Revising relevant laws to consider context, alternative measures of maturity, and evolving societal views about adolescence, along with supporting caregivers to assist in developing adolescent autonomy may promote more equitable and representative participation of adolescents in HIV care and research. Additional research should explore how to support caregivers and other adults to empower adolescents and improve stakeholder engagement in a more routine process of policy reform.

RESUMO

INTRODUCTION: Adolescents and youth living with HIV (AYLHIV) have lower retention in care, adherence to treatment, and viral suppression compared with adults. Stepped care is a process by which clients are assigned to increasingly intensive services or 'steps' according to level of need. Differentiated care, in which stable clients access less frequent services, can be combined with stepped care to align needs and preferences of youth to promote optimal engagement in care. METHODS AND ANALYSIS: This hybrid type I effectiveness implementation cluster randomised trial aims to evaluate a data-informed stepped care (DiSC) intervention for AYLHIV. AYLHIV ages 10-24 receiving care at 24 HIV treatment facilities in Kisumu, Homabay and Migori counties in Kenya will be enrolled. Twelve facilities will be randomised to the DiSC intervention, and 12 will provide standard care. A clinical assignment tool developed by the study team will be used at intervention sites to assign AYLHIV to one of four steps based on risk for loss to follow-up: differentiated care, standard care, counselling services or intensive support services. The primary clinical outcome is retention in care, specifically missed visits (failure to return within 30 days for any visit) and 12-month loss to follow-up. Implementation outcomes are based on the Reach, Effectiveness, Adoption, Implementation and Maintenance framework. Proportions of missed visits will be compared using mixed effect models clustered by facility and participant. ETHICS AND DISSEMINATION: This study has been approved by the University of Washington Institutional Review Board (STUDY00011096), Maseno University Ethical Review Committee (MUERC/00917/20) and the Kenya National Commission for Science, Technology and Innovation (444824). AYLHIV provide written informed consent when legally permitted, or assent with caregiver permission for minors. Study staff will work with a Community Advisory Board, including youth members, to disseminate results via discussions, presentations, journal publications and local or international conferences. TRIAL REGISTRATION NUMBER: NCT05007717.

RESUMO

OBJECTIVES: People who inject drugs (PWID) in Kenya have high HIV (range across settings: 14-26%) and hepatitis C virus (HCV; 11-36%) prevalence. We evaluated the impact of existing and scaled-up interventions on HIV and HCV incidence among PWID in Kenya. DESIGN: HIV and HCV transmission model among PWID, calibrated to Nairobi and Kenya's Coastal region. METHODS: For each setting, we projected the impact (percent of HIV/HCV infections averted in 2020) of existing coverages of antiretroviral therapy (ART; 63-79%), opioid agonist therapy (OAT; 8-13%) and needle and syringe programmes (NSP; 45-61%). We then projected the impact (reduction in HIV/HCV incidence over 2021-2030), of scaling-up harm reduction [Full harm reduction ('Full HR'): 50% OAT, 75% NSP] and/or HIV (UNAIDS 90-90-90) and HCV treatment (1000 PWID over 2021-2025) and reducing sexual risk (by 25/50/75%). We estimated HCV treatment levels needed to reduce HCV incidence by 90% by 2030. RESULTS: In 2020, OAT and NSP averted 46.0-50.8% (range of medians) of HIV infections and 50.0-66.1% of HCV infections, mostly because of NSP. ART only averted 12.9-39.8% of HIV infections because of suboptimal viral suppression (28-48%). Full HR and ART could reduce HIV incidence by 51.5-64% and HCV incidence by 84.6-86.6% by 2030. Also halving sexual risk could reduce HIV incidence by 68.0-74.1%. Alongside full HR, treating 2244 PWID over 2021-2025 could reduce HCV incidence by 90% by 2030. CONCLUSION: Existing interventions are having substantial impact on HIV and HCV transmission in Kenya. However, to eliminate HIV and HCV, further scale-up is needed with reductions in sexual risk and HCV treatment.

RESUMO

BACKGROUND AND AIMS: Hepatitis C virus (HCV) treatment is essential for eliminating HCV in people who inject drugs (PWID), but has limited coverage in resource-limited settings. We measured the cost-effectiveness of a pilot HCV screening and treatment intervention using directly observed therapy among PWID attending harm reduction services in Nairobi, Kenya. DESIGN: We utilized an existing model of HIV and HCV transmission among current and former PWID in Nairobi to estimate the cost-effectiveness of screening and treatment for HCV, including prevention benefits versus no screening and treatment. The cure rate of treatment and costs for screening and treatment were estimated from intervention data, while other model parameters were derived from literature. Cost-effectiveness was evaluated over a life-time horizon from the health-care provider's perspective. One-way and probabilistic sensitivity analyses were performed. SETTING: Nairobi, Kenya. POPULATION: PWID. MEASUREMENTS: Treatment costs, incremental cost-effectiveness ratio (cost per disability-adjusted life year averted). FINDINGS: The cost per disability-adjusted life-year averted for the intervention was $975, with 92.1% of the probabilistic sensitivity analyses simulations falling below the per capita gross domestic product for Kenya ($1509; commonly used as a suitable threshold for determining whether an intervention is cost-effective). However, the intervention was not cost-effective at the opportunity cost-based cost-effectiveness threshold of $647 per disability-adjusted life-year averted. Sensitivity analyses showed that the intervention could provide more value for money by including modelled estimates for HCV disease care costs, assuming lower drug prices ($75 instead of $728 per course) and excluding directly-observed therapy costs. CONCLUSIONS: The current strategy of screening and treatment for hepatitis C virus (HCV) among people who inject drugs in Nairobi is likely to be highly cost-effective with currently available cheaper drug prices, if directly-observed therapy is not used and HCV disease care costs are accounted for.

RESUMO

PURPOSE: To improve testing coverage, it is imperative to determine adolescent girls and young women (AGYW) preferences about HIV testing modality and where they prefer receiving services. METHODS: Participants were enrolled between May 2017 and April 2018 from three sites in Homa Bay County, Nyanza region, western Kenya. We explored two recruitment approaches (home-based vs. mobile-event based) and three HIV testing options (oral self-test, staff-administered, or referral to health facility). Exact logistic regression compared yield of newly diagnosed HIV and high-risk HIV-negatives from the recruitment and testing option strategies. RESULTS: A total of 1,198 participants were enrolled, 1,046 (87.3%) at home and 152 (12.7%) at mobile events. Most participants (928, 77.5%) chose staff-aided testing either at home or at a mobile event; 268 (22.4%) chose self-testing; and only 2 (.2%) chose facility referral. Prevalence of newly diagnosed HIV-positives was 2.7% (32/1,198) and 36.8% (429/1,166) of HIV-negative AGYW were identified as high risk. We identified more newly diagnosed HIV infection among AGYW recruited at mobile events than at home (OR = 3.11; 95% CI: 1.33-6.74; p = .02). High-risk status was related to neither recruitment strategy nor testing modality. Older age was associated with increased odds of selecting an oral self-test (OR = 1.85; 95% CI: 1.06-3.22). CONCLUSIONS: More than one-third of AGYW were at elevated risk of HIV infection, and those unaware of their HIV infection were more likely to be identified at a mobile outreach. Though self-testing was not the dominant preferred strategy, self-tests were performed accurately and with high confidence. These findings can help inform efficient identification of undiagnosed HIV infection and high risk for seroconversion among AGYW in similar settings.

RESUMO

The purpose of this study was to analyze the association of developmental care education and training and neonatal intensive care unit (NICU) developmental team structure in promoting neonatal nursing perception and beliefs of key characteristics of family-centered care (FCC), developmental care, and kangaroo mother care (KMC). A 24-item Likert scale survey of specific perceptions and beliefs of aspects of FCC, KMC, and developmental care characteristics was conducted with 59 neonatal nurses from three distinct level III NICUs in New York City where nurses had undergone recent reeducation and developmental team configuration. There was no difference in nursing beliefs of technical developmental care approaches to infant care at all three sites. Neonatal nurses who were supported by an on-site infant developmental specialist were more likely to have strong beliefs related to the affective areas of FCC and the technique of KMC. FCC and clinical care approaches that include a high level of parental participation such as KMC in the NICU are likely to be facilitated by a comprehensive approach of continuing training as well as a team structure that includes dedicated, specially trained infant developmental specialist personnel.

RESUMO

In countries experiencing the dual burden of HIV disease and health care worker shortages, information and communication technology tools offer the potential to help support HIV treatment adherence and secondary HIV transmission risk reduction for people living with HIV/AIDS. We conducted a randomized controlled trial (September 1, 2011-July 12, 2012) with follow-up through April 2013. Participants were recruited from two clinics affiliated with the Academic Model Providing Access to Healthcare program in western Kenya. A total of 236 participants were enrolled, randomly assigned to intervention (n = 118) or risk-assessment only control (n = 118) and followed up for 9 months. Both arms had > 0.5 log10 reduction in viral load over time (p = .0007), a clinically relevant finding. A computer-based counseling tool is feasible and acceptable in a high-volume East African HIV setting and provides evidence-based ART adherence and risk reduction support that may extend health workforce deficits.

RESUMO

The purpose of this article is to review the current literature on the association between maternal periodontal disease and poor pregnancy and neonatal outcomes and outline the role nurses can play in improving the oral health of pregnant women. Maternal periodontal disease is linked to preterm birth, low birthweight, and preterm low birthweight, but treatment of periodontal disease during pregnancy has been shown to be safe and effective. Nurses, nurse practitioners, and nurse-midwives are in a position to educate pregnant women on the benefits of good oral health and identify and refer women who are in need of dental care for treatment.

RESUMO

PURPOSE OF REVIEW: Opioid use disorder (OUD) is a global phenomenon and is on the rise in Africa, denoting a shift from historical patterns of drug transport to internal consumption. In contrast, opioids for clinical pain management in Africa remain among the least available globally. This region also has the highest HIV and HCV disease burden, and the greatest shortages of health workers and addiction treatment. We undertook a systematic review of the literature to describe opioid use in Africa and how it is being addressed. RECENT FINDINGS: A total of 84 articles from 2000 to 2018 were identified. Descriptions of country-specific populations and patterns of opioid misuse were common. A smaller number of articles described interventions to address OUD. SUMMARY: OUD occurs in sub-Saharan Africa, with attendant clinical and social costs. Evidence-based policies and health system resources are needed to promote OUD prevention and management, and infectious disease transmission reduction.

RESUMO

Deaths of children due to neglected dental diseases have put the issue of access to care by minorities at the forefront of dental public health discussions. We evaluated the trends in dental service utilization in relation to racial disparities and other factors using Medicaid enrollment and claims data from 1990 to 1997 for Alabama children 19 years of age and younger (N=512,049). Alabama Medicaid children visited the dentist at a low and declining rate. The number of participating providers gradually declined over time and the racial disparities in service utilization were related to the availability of a local provider. Lower service utilization, however, was not a simple function of race, but a complex interaction of race with age and gender. Identification of these complex interactions and removal of barriers to service utilization in race, age, and gender sub-groups will help the U.S. meet the year 2010 oral health objectives.

RESUMO

BACKGROUND: Sub-Saharan Africa is the region with the highest HIV burden. Adolescent girls and young women (AGYW) in the age range of 15 to 24 years are twice as likely as their male peers to be infected, making females in sub-Saharan Africa the most at-risk group for HIV infection. It is therefore critical to prioritize access to HIV testing, prevention, and treatment for this vulnerable population. OBJECTIVE: Using an implementation science framework, the purpose of this research protocol was to describe the approaches we propose to optimize engagement of AGYW in both the HIV prevention and care continuum and to determine the recruitment and testing strategies that identify the highest proportion of previously undiagnosed HIV infections. METHODS: We will compare two seek recruitment strategies, three test strategies, and pilot adaptive linkage to care interventions (sequential multiple assignment randomized trial [SMART] design) among AGYW in the age range of 15 to 24 years in Homa Bay County, western Kenya. AGYW will be recruited in the home or community-based setting and offered three testing options: oral fluid HIV self-testing, staff-aided rapid HIV testing, or referral to a health care facility for standard HIV testing services. Newly diagnosed AGYW with HIV will be enrolled in the SMART trial pilot to determine the most effective way to support initial linkage to care after a positive diagnosis. They will be randomized to standard referral (counseling and a referral note) or standard referral plus SMS text message (short message service, SMS); those not linked to care within 2 weeks will be rerandomized to receive an additional SMS text message or a one-time financial incentive (approximately US $4). We will also evaluate a primary prevention messaging intervention to support identified high-risk HIV-negative AGYW to reduce their HIV risk and adhere to HIV retesting recommendations. We will also conduct analyses to determine the incremental cost-effectiveness of the seek, testing and linkage interventions. RESULTS: We expect to enroll 1200 participants overall, with a random selection of 100 high-risk HIV-negative AGYW for the SMS prevention intervention (HIV-negative cohort) and approximately 108 AGYW who are living with HIV for the SMART design pilot of adaptive linkage to care interventions (HIV-positive cohort). We anticipate that the linkage to care interventions will be feasible and acceptable to implement. Lastly, the use of SMS text messages to engage participants will provide pilot data to the Kenyan government currently exploring a national platform to track and support linkage, adherence to treatment, retention, and prevention interventions for improved outcomes. CONCLUSIONS: Lessons learned will inform best approaches to identify new HIV diagnoses to increase AGYW's uptake of HIV prevention, testing, and linkage to care services in a high HIV-burden African setting.
