Cultural Considerations for Patient and Community Education in Global Health: A Qualitative Study in Lesotho.

Background: In global health, international nongovernmental organizations (NGOs) frequently hire, train, and partner with host-country clinicians who manage public outreach and patient care. Purpose and Research Design: We conducted a general interpretivist study of Basotho clinicians hired by NGOs and academic affiliates in Lesotho to identify cultural barriers and facilitators to community and patient education. Data Collection and Analysis: We conducted 13 interviews involving 16 participants (one physician, one nutritionist, 14 nurses). Using an inductive and iterative approach, we analyzed interview transcripts through the lens of social cognitive theory and identified 15 themes. Results: Major findings highlighted: 1) patient and community learners may view Basotho clinicians as authority figures; 2) family and community power dynamics affect healthcare access for vulnerable patient groups; and 3) village leaders may refuse community education when excluded from problem-solving and early planning. Conclusions: Although local clinicians and community members may identify with the same cultural group, clinicians can encounter cultural barriers to patient and community education.

COVID-19 advanced respiratory care educational training programme for healthcare workers in Lesotho: an observational study.

OBJECTIVE: To develop and implement a 'low-dose, high-frequency' (LDHF) advanced respiratory care training programme for COVID-19 care in Lesotho. DESIGN: Prospective pretraining-post-training evaluation. SETTING: Lesotho has limited capacity in advanced respiratory care. PARTICIPANTS: Physicians and nurses. INTERVENTIONS: Due to limited participation in May-September 2020, the LDHF approach was modified into a traditional 1-day offsite training in November 2020 that reviewed respiratory anatomy and physiology, clinical principles for conventional oxygen, heated high-flow nasal cannula and non-invasive ventilation management. Basic mechanical ventilation principles were introduced. OUTCOME MEASURES: Participants completed a 20-question multiple choice examination immediately before and after the 1-day training. Paired t-tests were used to evaluate the difference in average participant pretraining and post-training examination scores. RESULTS: Pretraining and post-training examinations were completed by 46/53 (86.7%) participants, of whom 93.4% (n=43) were nurses. The overall mean pretraining score was 44.8% (SD 12.4%). Mean scores improved by an average of 23.7 percentage points (95% CI 19.7 to 27.6, p<0.001) on the post-training examination to a mean score of 68.5% (SD 13.6%). Performance on basic and advanced respiratory categories also improved by 17.7 (95% CI 11.6 to 23.8) and 25.6 percentage points (95% CI 20.4 to 30.8) (p<0.001). Likewise, mean examination scores increased on the post-training test, compared with pretraining, for questions related to respiratory management (29.6 percentage points, 95% CI 24.1 to 35.0) and physiology (17.4 percentage points, 95% CI 12.0 to 22.8). CONCLUSIONS: An LDHF training approach was not feasible during this early emergency period of the COVID-19 pandemic in Lesotho. Despite clear knowledge gains, the modest post-training examination scores coupled with limited physician engagement suggest healthcare workers require alternative educational strategies before higher advanced care like mechanical ventilation is implementable. Conventional and high-flow oxygen is better aligned with post-training healthcare worker knowledge levels and rapid implementation.

Cultural considerations in health care capacity building: A qualitative study in Lesotho.

International non-governmental organisations (NGOs) and academic institutions support health care capacity building to strengthen health systems in low and middle-income countries. We conducted a phenomenological study of foreign and Basotho clinicians who participated in clinical continuing professional development (CPD) in Lesotho. Clinicians included physicians, nurses, and a nutritionist. We sought to understand, through the lens of social cognitive theory, how cultural differences between foreign and Basotho clinicians affected bidirectional clinical education led by NGOs and academic institutions. We also assessed how Basotho clinical educators considered culture when leading NGO-sponsored clinical CPD for Basotho clinicians. After analysing 17 interviews with 24 total participants (four foreign educators, 11 Basotho educators, and nine Basotho learners), using an iterative and inductive approach, we identified 17 themes within the cognitive, environmental, and behavioural domains. Key findings highlighted: (1) cultural tensions between foreign and Basotho culture, including bias against traditional culture; (2) power structures which affected the efficacy of in-service training strategies; (3) perceptions among foreign educators that technical assistance was more effective than direct service delivery at promoting education and sustainability. Educators should map out key relationships and engage local and foreign stakeholders in culturally-focused targeted needs assessments to improve curricular design in capacity building.

Tuberculosis symptom screening for children and adolescents living with HIV in six high HIV/TB burden countries in Africa.

OBJECTIVES: The WHO recommends that children and adolescents living with HIV (CALHIV) complete TB symptom screening at every clinical encounter but evidence supporting this recommendation is limited. We evaluated the performance of the recommended TB symptom screening in six high-burden TB/HIV countries. DESIGN: Retrospective longitudinal cohort. METHODS: We extracted data from electronic medical records of CALHIV receiving care from clinics in Botswana, Eswatini, Lesotho, Malawi, Tanzania, and Uganda from January 2014 to June 2017. We defined incident TB cases as those prescribed TB treatment within 30 days of TB diagnosis. We analyzed the most recent symptom screen preceding a TB diagnosis. In accordance with WHO guidelines, positive screens were defined as current fever, cough, poor weight gain, or recent TB contact. Odds of TB disease was modeled by screen result and age at which screening was conducted. RESULTS: Twenty thousand seven hundred and six patients collectively had 316 740 clinic visits, of which 240 161 (75.8%) had documented TB symptom screens. There were 35 701 (14.9%) positive TB symptom screens, and 1212 incident TB diagnoses. Sensitivity and specificity of the TB symptom screen to diagnose TB were 61.2% (95% CI 58.4--64.0) and 88.8% (95% CI 88.7--88.9), respectively. Log odds of documented TB for positive or negative screens was statistically different only for screens conducted at ages 7--17. CONCLUSION: Although specificity was high, the sensitivity of the TB symptom screen to detect TB in CALHIV was low. More accurate screening approaches are needed to optimally identify TB disease in CALHIV.

Beyond the facility: An evaluation of seven community-based pediatric HIV testing strategies and linkage to care outcomes in a high prevalence, resource-limited setting.

Diverse challenges in expanding pediatric HIV testing and treatment coverage persist, making the investigation and adoption of innovative strategies urgent. Evidence is mounting for the effectiveness of community-based testing in bringing such lifesaving services to those in need, particularly in resource-limited settings. The Mobilizing HIV Identification and Treatment project piloted seven community-based testing strategies to assess their effectiveness in reaching HIV-positive children and linking them to care in two districts of Lesotho from October 2015 to March 2018. Children testing HIV-positive were enrolled into the project's mHealth system where they received e-vouchers for transportation assistance to the facility for treatment initiation and were followed-up for a minimum of three months. An average of 7,351 HIV tests were conducted per month across all strategies for all age groups, with 46% of these tests on children 0-14 years. An average of 141.65 individuals tested positive each month; 9% were children. Among the children tested 55% were over 5 years. The yield in children was low (0.38%), however facility-based yields were only slightly higher (0.72%). Seventy-five percent of children were first-time testers and 86% of those testing HIV-positive were first-time testers. Seventy-one percent of enrolled children linked to care, all but one initiated treatment, and 82% were retained in care at three months. As facility-based testing remains the core of HIV programs, this evaluation demonstrates the effectiveness of community-based strategies in finding previously untested children and those over 5 years who have limited interactions with the conventional health system. Utilizing active follow-up mechanisms, linkage rates were high suggesting accessing treatment in a facility after community testing is not a barrier. Overall, these community-based testing strategies contributed markedly to the HIV testing landscape in which they were implemented, demonstrating their potential to help close the gap of unidentified HIV-positive children and achieve universal testing coverage.

Reciprocity? International Preceptors' Perceptions of Global Health Elective Learners at African Sites.

BACKGROUND: Short-term global health electives (STGHEs) have become increasingly common, with evidence showing educational and clinical benefits for short-term learners (STLs). Despite increased recognition that STGHEs should be mutually beneficial for host sites and STLs, evidence demonstrating the impact on international host preceptors is lacking. OBJECTIVES: To understand international host preceptors' perceptions regarding benefits and burdens of hosting STLs. METHODS: Focus group discussions with a convenience sample of 10 of 18 eligible preceptors were conducted at pediatric STGHE sites in Malawi and Lesotho. Qualitative content analysis was performed to identify themes using a deductive-inductive approach. FINDINGS: Common themes regarding benefits to preceptors included increased knowledge and resources for learning from STLs, broadened differential diagnoses, and the satisfaction of teaching. Regarding burdens, preceptors perceived that supervising STLs decreases efficiency. Preceptors identified the burden of having to intervene in instances that could lead to patient harm. Some preceptors perceived that STLs under-valued preceptors' clinical decision-making in resource-limited contexts. CONCLUSIONS: Our findings emphasize the need for institutions to identify mutuality of benefits between STLs and host sites when developing STGHEs. Host preceptors identified robust pre-departure training for STLs, lengthened duration of STGHEs, and formal preceptor orientation as ways to enhance mutuality of benefits.

Development of a Tool for Health Screening and Assessment in Orphanages in Lesotho.

In low- and middle-income countries that have high burdens of disease, simple interventions such as health screenings can have a significant impact on health outcomes. Among vulnerable children, orphans in particular, deaths are often caused by conditions preventable through early identification and provision of basic health and nutritional needs. After consulting local preventative care guidelines and medical providers, a health screening tool for use in orphanages was created. This tool was used to screen children in two orphanages in Lesotho. Overall, the tool was found to be easy, efficient, and valuable in identifying both preventable and immediately treatable conditions in orphans. As a result, orphans with long-term medical needs were linked to community-based providers by developing individualized care plans in collaboration with orphanage colleagues. This preventative tool offers a screening strategy that directly aligns with the United Nations Agency for Development's Sustainable Development Goals and helps to advance the goal of universal health coverage.

Host clinical preceptors' perceptions of professionalism among learners completing global health electives.

OBJECTIVES: This study aims to gain an understanding of the perceptions of host clinical preceptors in Malawi and Lesotho of the professionalism exhibited by short-term learners from the United States and Canada during short-term global health electives. METHODS: Focus group discussions were conducted with 11 host clinical preceptors at two outpatient pediatric HIV clinics in sub-Saharan Africa (Malawi and Lesotho). These clinics host approximately 50 short-term global health learners from the United States and Canada each year. Focus group moderators used open-ended discussion guides to explore host clinical preceptors' perceptions of the professionalism of short-term global health learners. Thematic analysis with an inductive approach was used to identify salient themes from these focus group discussions. RESULTS: Eleven of the 18 possible respondents participated in two focus group discussions. Adaptability, eagerness to learn, active listening, gratitude, initiative, and punctuality was cited as professional behaviors among short-term global health learners. Cited unprofessional behaviors included disregard of local clinicians' expertise and unresponsiveness to feedback. Host clinical preceptors described difficulty providing feedback to short-term global health learners and discrepancies between what may be considered professional in their home setting versus in the study settings. Respondents requested pre-departure orientation for learners and their own orientation before hosting learners. CONCLUSIONS: Both host clinical preceptors and short-term global health learners should be aware that behaviors that may be considered best practice in one clinical setting may be perceived as unprofessional in another. Future studies to develop a common definition of professionalism during short-term global health electives are merited.

Community-Based Interventions to Reach 95-95-95 for Children and Adolescents: An Exploratory Programmatic Review From Lesotho.

BACKGROUND: Viral suppression is the desired outcome for children and adolescents with HIV. In this article, data from districts supporting community interventions (implementation districts) were reviewed and compared with data from districts without community interventions (nonimplementation districts) to explore a potential correlation between community interventions and clinical outcomes. SETTING: The study was based on data collected from facilities in 6 districts in Lesotho. METHODS: Twelve-month retention, viral load coverage, and viral suppression data from patients with ART between ages 5 and 24 from facilities in both district types were collected retrospectively. RESULTS: Implementation districts showed retention rates of 75%, with 5365 patients (47% of all patients on ART) having documented viral load results and 4641 (87%) being virally suppressed. Retention comparison demonstrated significantly higher rates in implementation districts (73%) as compared to (63%) in nonimplementation districts (P = 0.023). Viral load coverage and suppression comparison found that implementation district hospitals reported 632 (37% of total on ART) patients with a documented viral load, with 539 (85%) virally suppressed, whereas nonimplementation district hospitals reported 220 (31%) patients with viral load results, of whom 181 (82%) were suppressed. CONCLUSIONS: Overall, retention rates in the implementation districts were reasonable and were significantly better than the rates in the nonimplementation districts.

False-negative post-18-month confirmatory HIV tests in HIV DNA PCR-positive children: a retrospective analysis.

OBJECTIVE: The WHO guidelines for children less than 18 months old diagnosed with HIV based on presumptive clinical diagnosis or one virologic test recommend confirmatory HIV antibody testing after 18 months of age. This study describes post-18-month HIV test results following this WHO-recommended confirmatory testing strategy. DESIGN: Case series and retrospective review of routine program data. METHODS: Children enrolled at the Baylor Children's Clinical Center of Excellence, a pediatric and family HIV clinic in Maseru, Lesotho from December 2005 through January 2009 with a positive HIV DNA PCR at less than 18 months of age and HIV rapid test results after 18 months of age were included. Post-18-month confirmatory HIV test results are described. Factors associated with non-positive confirmatory rapid tests were determined using binary logistic regression. RESULTS: Of the 109 children meeting inclusion criteria, 22 (20.2%) had negative and 27 (24.8%) discordant confirmatory rapid tests. Forty-six of these 49 were on antiretroviral therapy (ART). Among these 49, 11 of 24 post-18-month HIV DNA PCRs were negative, whereas nine of 10 post-18-month HIV ELISAs were positive; 29 were definitively and 17 probably HIV-infected, two were uninfected, and one had undetermined status. Only age less than 9 months at ART initiation (odds ratio 4.25, P = 0.002) was associated with non-positive rapid tests. CONCLUSION: False-negative post-18-month confirmatory rapid tests and HIV DNA PCRs in children on ART are common, associated with early ART initiation, and may lead to inappropriate ART discontinuation and discharge from care of truly HIV-infected children.

The effects of enamel matrix derivative and cyclic mechanical strain on human gingival fibroblasts in an in vitro defect healing model.

Gingival fibroblasts (GFs) play a considerable role in the maintenance of the gingival apparatus as well as in connective tissue repair. Mobility of a periodontal wound or soft tissue graft can impair connective tissue healing from the GFs. Enamel matrix derivative (EMD) is an enamel matrix protein used clinically for periodontal regeneration of intrabony defects and furcations, as well as treatment of gingival margin recessions. The goal of this project was to compare the effects of varying concentrations of EMD, with and without cyclic mechanical strain, on cellular wound fill of human GFs using an in vitro defect healing model. GFs were seeded and cultured in six-well flexible-bottomed plates. A 3-mm wound was created in the central portion of each confluent well. Three wells were treated with each EMD concentration of 0 Μg/mL (control), 30 Μg/mL, 60 Μg/mL, or 120 Μg/mL. The plates were placed in an incubator containing a strain unit to subject test plates to cyclic strain. An identical set of control plates were not flexed. Cells were examined on days 4, 8, 12, and 16. Microphotographs were taken and wound fill measurements made using image analysis software. The percent wound fill was calculated. All nonflexed plates, regardless of EMD concentration, reached > 90% defect fill at similar rates by day 16. However, in the flexed plates, EMD had a significant negative effect on defect fill. The defect fill was 55.7% for 0 Μg/mL EMD, 48.2% for 30 Μg/mL EMD, 36.7% for 60 Μg/mL EMD, and 34.1% for 120 Μg/mL EMD on day 16 for the flexed GFs. EMD, in concentrations as high as 120 Μg/mL, did not significantly affect the amount of defect fill with nonflexed GFs. However, when the GFs were flexed, the addition of EMD had a significant negative effect on defect fill in a dose-dependent manner.

Early identification and assessment of new and emerging health technologies: actions, progress, and the future direction of an international collaboration--EuroScan.

OBJECTIVES: To report on a workshop, and subsequent discussions, that reviewed the achievements and progress of the EuroScan collaboration since its establishment in 1999 to share information on the methods and results of early identification and assessment of new and emerging health technologies; considered challenges to the collaboration; and discussed its possible future direction. METHODS: A workshop was held in Stockholm in September 2006, with thirty-two participants from ten countries and representatives from EuroScan member agencies, policy makers involved in policy or decision making relating to new technologies, and invited external commentators from international HTA networks. The workshop used a mix of presentations, panel and audience discussions, and small group work to consider the achievements and challenges put forward. RESULTS: EuroScan has developed as a sustainable network, and has made progress on all tasks in its initial action plan, with the EuroScan information sharing database on new and emerging technologies being one of the collaboration's key achievements. Identified immediate concerns for the network included consideration of the impact of its current name and membership model; acknowledgement and publication of the full range of benefits of membership; contribution to and development of the database to encourage increased information sharing; and EuroScan's ongoing interaction with the wider HTA world. CONCLUSIONS: The workshop was a useful mechanism for reviewing the work of EuroScan and for creating a platform to take the collaboration forward. The workshop affirmed the benefits of the network to individual members; posed some significant challenges to the network to consider; and acted as a stimulus for an interim name change to better represent the global membership, and a major review of the EuroScan database of identified and assessed emerging health technologies.

Challenges, choices, and Canada.

The Canadian Coordinating Office for Health Technology Assessment (CCOHTA) was established by the Federal, Provincial, and Territorial Ministers of Health in 1989 for a 3-year trial period. In 1993 CCOHTA was made a permanent organization and in 1999 the Deputy Ministers of Health renewed CCOHTA's mandate and increased its funding. CCOHTA's role is to coordinate health technology assessment (HTA) priorities across jurisdictions, foster and undertake assessment activity, and function as a clearinghouse for technology assessment results while increasing healthcare system stakeholder awareness of HTA findings. The coordinated and collaborated approach adopted by CCOHTA minimizes duplication with other national and provincial organizations and contributes to the ability of the Canadian healthcare system to continue to deliver high-quality health care to its constituents.
