Climate change, malaria and neglected tropical diseases: a scoping review.

To explore the effects of climate change on malaria and 20 neglected tropical diseases (NTDs), and potential effect amelioration through mitigation and adaptation, we searched for papers published from January 2010 to October 2023. We descriptively synthesised extracted data. We analysed numbers of papers meeting our inclusion criteria by country and national disease burden, healthcare access and quality index (HAQI), as well as by climate vulnerability score. From 42 693 retrieved records, 1543 full-text papers were assessed. Of 511 papers meeting the inclusion criteria, 185 studied malaria, 181 dengue and chikungunya and 53 leishmaniasis; other NTDs were relatively understudied. Mitigation was considered in 174 papers (34%) and adaption strategies in 24 (5%). Amplitude and direction of effects of climate change on malaria and NTDs are likely to vary by disease and location, be non-linear and evolve over time. Available analyses do not allow confident prediction of the overall global impact of climate change on these diseases. For dengue and chikungunya and the group of non-vector-borne NTDs, the literature privileged consideration of current low-burden countries with a high HAQI. No leishmaniasis papers considered outcomes in East Africa. Comprehensive, collaborative and standardised modelling efforts are needed to better understand how climate change will directly and indirectly affect malaria and NTDs.

The Better Operative Outcomes Software Tool (BOOST) Prospective Study: Improving the Quality of Cataract Surgery Outcomes in Low-Resource Settings.

PURPOSE: Post-operative vision impairment is common among patients who have undergone cataract surgery in low-resource settings, impacting quality of clinical outcomes and patient experience. This prospective, multisite, single-armed, pragmatic validation study aimed to assess whether receiving tailored recommendations via the free Better Operative Outcomes Software Tool (BOOST) app improved surgical outcomes, as quantified by post-operative unaided distance visual acuity (UVA) measured 1-3 days after surgery. METHODS: During the baseline data collection round, surgeons in low and middle-income countries recorded clinical characteristics of 60 consecutive cataract cases in BOOST. Additional data on the causes of poor outcomes from 20 consecutive cases with post-operative UVA of <6/60 (4-12 weeks post-surgery) were entered to automatically generate tailored recommendations for improvement, before 60 additional consecutive cases were recorded during the follow-up study round. Average UVA was compared between cases recorded in the baseline study round and those recorded during follow-up. RESULTS: Among 4,233 cataract surgeries performed by 41 surgeons in 18 countries, only 2,002 (47.3%) had post-operative UVA 6/12 or better. Among the 14 surgeons (34.1%) who completed both rounds of the study (1,680 cases total), there was no clinically significant improvement in post-operative average UVA (logMAR units ±SD) between baseline (0.50 ± 0.37) and follow-up (0.47 ± 0.36) rounds (mean improvement 0.03, p = 0.486). CONCLUSIONS: Receiving BOOST-generated recommendations did not result in improved UVA beyond what could be expected from prospective monitoring of surgical outcomes alone. Additional research is required to assess whether targeted support to implement changes could potentiate the uptake of app-generated recommendations and improve outcomes.

Tropical Data: Approach and Methodology as Applied to Trachoma Prevalence Surveys.

PURPOSE: Population-based prevalence surveys are essential for decision-making on interventions to achieve trachoma elimination as a public health problem. This paper outlines the methodologies of Tropical Data, which supports work to undertake those surveys. METHODS: Tropical Data is a consortium of partners that supports health ministries worldwide to conduct globally standardised prevalence surveys that conform to World Health Organization recommendations. Founding principles are health ministry ownership, partnership and collaboration, and quality assurance and quality control at every step of the survey process. Support covers survey planning, survey design, training, electronic data collection and fieldwork, and data management, analysis and dissemination. Methods are adapted to meet local context and needs. Customisations, operational research and integration of other diseases into routine trachoma surveys have also been supported. RESULTS: Between 29th February 2016 and 24th April 2023, 3373 trachoma surveys across 50 countries have been supported, resulting in 10,818,502 people being examined for trachoma. CONCLUSION: This health ministry-led, standardised approach, with support from the start to the end of the survey process, has helped all trachoma elimination stakeholders to know where interventions are needed, where interventions can be stopped, and when elimination as a public health problem has been achieved. Flexibility to meet specific country contexts, adaptation to changes in global guidance and adjustments in response to user feedback have facilitated innovation in evidence-based methodologies, and supported health ministries to strive for global disease control targets.

Integrating eye care in low-income and middle-income settings: a scoping review.

OBJECTIVES: Integrated people-centred eye care has been recommended as a strategic framework for reducing global vision impairment and blindness. The extent to which eye care has integrated with other services has not been widely reported. We aimed to investigate approaches to integrating eye care service delivery with other systems in low resource settings, and identify factors associated with integration. DESIGN: Rapid scoping review based on Cochrane Rapid Review and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. DATA SOURCES: MEDLINE, Embase, Web of Science, Scopus and Cochrane Library databases were searched in September 2021. ELIGIBILITY CRITERIA: Papers with interventions involving eye care or preventative eye care integrated into other health systems, peer-reviewed in English, conducted in low-income or middle-income countries, and published between January 2011 and September 2021 were included. DATA EXTRACTION AND SYNTHESIS: Two independent reviewers screened, quality appraised and coded included papers. A deductive-inductive iterative analysis approach was used with a focus on integrating service delivery. RESULTS: The search identified 3889 potential papers, of which 24 were included. Twenty papers incorporated more than one intervention type (promotion, prevention and/or treatment), but none included rehabilitation. Most articles involved human resources development yet rarely appeared to be people-centred. The level of integration was associated with building relationships and enhancing service coordination. Integrating human resources was challenged by the need for ongoing support and worker retention. In primary care settings, workers were often already at full capacity, had competing priorities, varying capabilities and limited motivation. Additional barriers included inadequate referral and information systems, poor supply chain management and procurement practices and finite financing. CONCLUSION: Integrating eye care into low resource health systems is a challenging task, compounded by resource limitations, competing priorities and ongoing support needs. This review highlighted a need for people-centred approaches to future interventions, and further investigation into integrating vision rehabilitation services.

Comparison of Face Washing and Face Wiping Methods for Trachoma Control: A Pilot Study.

Eye-to-eye transmission of Chlamydia trachomatis, the causative agent of trachoma, may be plausibly interrupted if faces are kept free of ocular and nasal discharge. Between April and June 2018, 83 children aged 1-9 years with active trachoma were recruited from 62 households and allocated to a face cleaning protocol: face washing with water, face washing with water and soap, or face wiping. Faces were examined for the presence of ocular and nasal discharge, and swabs were taken from faces and hands to test for C. trachomatis at baseline, immediately post protocol, and after 1, 2, and 4 hours (washing protocols). Washing with soap was more effective at removing ocular discharge than either washing with water (89% and 27% of discharge removed, respectively, P = 0.003) or wiping with a hand (42%, P = 0.013). The reduction in prevalence of ocular discharge was sustained for at least four hours. The prevalence of C. trachomatis on face swabs was reduced by all washing protocols. The importance of soap should not be overlooked during facial cleanliness promotion.

Who benefits most from extending financial protection for cataract surgery in Vietnam? An extended cost-effectiveness analysis of small incision surgery.

Treatment costs remain a barrier for having timely cataract surgery in Vietnam, particularly for females and the poor, despite significant progress in achieving universal health coverage (UHC). This study evaluated the potential impact, on health and financial protection, of eliminating medical and non-medical out-of-pocket costs associated with cataract surgery. An extended cost-effectiveness analysis (ECEA) was conducted with a societal perspective. The ECEA modelled how many more disability-adjusted life years (DALYs) and cases of catastrophic health expenditure (CHE) and medical impoverishment could be averted across income quintiles and between males and females. Two programmes were evaluated: (1) eliminating medical out-of-pocket costs for small incision cataract surgery and (2) Programme A plus a voucher programme covering non-medical out-of-pocket costs. Compared with current, the incremental cost per year of Programme A was estimated to be $833 396 and $1 641 835 for Programme B, each representing <0.01% of total health care spending in 2016. Males and females in the richest income quintiles would avert more DALYs than those in the poorest quintiles. For both programmes, most cases of CHE would be averted by individuals in the poorest income quintile. Programme B would avert the most CHE cases overall and females would have a greater share of benefits. All cases of impoverishing medical expenditure would be averted by individuals in the poorest quintile (A: 115 cases and B: 493 cases) for both programmes. The cost to avert each case of CHE with Programme A ranged from $67 to $292 and $100 to $232 for Programme B. We found a pro-rich health distribution and a pro-poor CHE distribution associated with eliminating out-of-pocket costs of cataract surgery in Vietnam. A programme that addressed both medical and non-medical out-of-pocket costs could have the greatest impact on improving financial protection in this population, particularly among the poorest income quintiles and for females. This study supports the concordance between the objectives of UHC and gender equity.

Field-Testing and Refinement of the Organisational Health Literacy Responsiveness Self-Assessment (Org-HLR) Tool and Process.

Health literacy refers to the skills and knowledge that influence a person's ability to access, understand and use information to make health-related decisions, which are influenced by the complexity of their health needs and the demands health services place on them. The aim of this study was to field-test the Organisational Health Literacy Responsiveness (Org-HLR) tool and process to determine their utility in assessing health literacy responsiveness and for supporting organisations to plan health literacy-related improvement activities. Four organisations in Victoria, Australia, field-tested the Org-HLR tool. Data were collected through direct observation, participant feedback, and focus groups. Forty-three individuals participated in field-testing activities, and 20 took part in focus group meetings. Themes relating to the applicability and utility of the Org-HLR self-assessment tool and process were identified. Field-testing resulted in a number of refinements to the tool and process. Twenty-eight indicators were removed, 29 were rephrased to improve their clarity, and four new indicators were added. The revised Org-HLR self-assessment tool contains six dimensions, 22 sub-dimensions and 110 performance indicators. The Org-HLR tool and process were perceived as useful for assessing health literacy responsiveness, prioritising improvement activities, and establishing a benchmark for monitoring and evaluation of improvements over time. Testing generated an improved Org-HLR tool and assessment process that are likely to have utility across a broad range of health and social service sector organisations.

Adding value to remote monitoring: Co-design of a health literacy intervention for older people with chronic disease delivered by telehealth - The telehealth literacy project.

OBJECTIVE: To co-design, test and evaluate a health literacy, chronic disease self-management and social support intervention for older people delivered by group videoconferencing into the home. METHOD: The Telehealth Literacy Project (THLP) was a mixed methods, quasi-experimental, non-randomised trial nested within a telehealth remote monitoring study. An intervention group (n = 52) participated in five, weekly videoconference group meetings lasting for 1.5 h and a control group (n = 60) received remote monitoring only. Outcomes were measured using the nine-scale Health Literacy Questionnaire (HLQ) and two scales of the Health Education Impact Questionnaire (heiQ). Semi-structured interviews and focus group data were thematically analysed. RESULT: At 3 month follow-up, univariate analysis identified small effects in the intervention group only, with improved health literacy behaviours (five HLQ scales) and self-management skills (two heiQ scales). ANOVA of HLQ scales indicated no significant differences between the two groups over time indicating a contributing effect of the remote monitoring project. Intervention participants reported improved perception of companionship, emotional and informational support. CONCLUSION: The THLP delivered with telemonitoring indicates potential to improve social support and some health literacy factors in older people. PRACTICE IMPLICATIONS: Patient education can be delivered by group videoconferencing.

Recruiting people with HIV to an online self-management support randomised controlled trial: barriers and facilitators.

Background Recruitment of people to randomised trials of online interventions presents particular challenges and opportunities. The aim of this study was to evaluate factors associated with the recruitment of people with HIV (PWHIV) and their doctors to the HealthMap trial, a cluster randomised trial of an online self-management program. METHODS: Recruitment involved a three-step process. Study sites were recruited, followed by doctors caring for PWHIV at study sites and finally PWHIV. Data were collected from study sites, doctors and patient participants. Factors associated with site enrolment and patient participant recruitment were investigated using regression models. RESULTS: Thirteen study sites, 63 doctor participants and 728 patient participants were recruited to the study. Doctors having a prior relationship with the study investigators (odds ratio (OR) 13.3; 95% confidence interval (CI) 3.0, 58.7; P = 0.001) was positively associated with becoming a HealthMap site. Most patient participants successfully recruited to HealthMap (80%) had heard about the study from their HIV doctor. Patient enrolment was associated with the number of people with HIV receiving care at the site (ß coefficient 0.10; 95% CI 0.04, 0.16; P = 0.004), but not with employing a clinic or research nurse to help recruit patients (ß coefficient 55.9; 95% CI -2.55, 114.25; P = 0.06). CONCLUSION: Despite substantial investment in online promotion, a previous relationship with doctors was important for doctor recruitment, and doctors themselves were the most important source of patient recruitment to the HealthMap trial. Clinic-based recruitment strategies remain a critical component of trial recruitment, despite expanding opportunities to engage with online communities.

The systematic development of a complex intervention: HealthMap, an online self-management support program for people with HIV.

BACKGROUND: Despite persistent calls for HIV care to adopt a chronic care approach, few HIV treatment services have been able to establish service arrangements that prioritise self-management. To prevent cardiovascular and other chronic disease outcomes, the HealthMap program aims to enhance routine HIV care with opportunities for self-management support. This paper outlines the systematic process that was used to design and develop the HealthMap program, prior to its evaluation in a cluster-randomised trial. METHODS: Program development, planning and evaluation was informed by the PRECEDE-PROCOEDE Model and an Intervention Mapping approach and involved four steps: (1) a multifaceted needs assessment; (2) the identification of intervention priorities; (3) exploration and identification of the antecedents and reinforcing factors required to initiate and sustain desired change of risk behaviours; and finally (4) the development of intervention goals, strategies and methods and integrating them into a comprehensive description of the intervention components. RESULTS: The logic model incorporated the program's guiding principles, program elements, hypothesised causal processes, and intended program outcomes. Grounding the development of HealthMap on a clear conceptual base, informed by the research literature and stakeholder's perspectives, has ensured that the HealthMap program is targeted, relevant, provides transparency, and enables effective program evaluation. CONCLUSIONS: The use of a systematic process for intervention development facilitated the development of an intervention that is patient centred, accessible, and focuses on the key determinants of health-related outcomes for people with HIV in Australia. The techniques used here may offer a useful methodology for those involved in the development and implementation of complex interventions.

Development of the Organisational Health Literacy Responsiveness (Org-HLR) self-assessment tool and process.

BACKGROUND: The World Health Organization describes health literacy as a critical determinant of health and driver of citizen empowerment and health equity. Several studies have shown that health literacy is associated with a range of socioeconomic factors including educational attainment, financial position and ethnicity. The complexity of the health system influences how well a person is able to engage with information and services. Health organisations can empower the populations they serve and address inequity by ensuring they are health literacy responsive. The aim of this study was to develop the Organisational Health Literacy Responsiveness self-assessment tool (Org-HLR Tool), and an assessment process to support organisations with application of the tool. METHODS: A co-design workshop with health and social service professionals was undertaken to inform the structure of the tool and assessment process. Participants critiqued existing self-assessment tools and discussed the likely utility of the data they generate. A review of widely used organisational performance assessment tools informed the structure and self-assessment process. The Organisational Health Literacy Responsiveness (Org-HLR) Framework (with seven domains/24 sub-domains) provided the structure for the assessment dimensions of the tool. The performance indicators were drawn from raw data collected during development of the Org-HLR Framework. RESULTS: Twenty-two professionals participated in the workshop. Based on the feedback provided and a review of existing tools, a multi-stage, group-based assessment process for implementing the Org-HLR Tool was developed. The assessment process was divided into three parts; i) reflection; ii) self-rating; and iii) priority setting, each supported by a corresponding tool. The self-rating tool, consistent with the Org-HLR Framework, was divided into: External policy and funding environment; Leadership and culture; Systems, processes and policies; Access to services and programs; Community engagement and partnerships; Communication practices and standards; Workforce. Each of these had 1 to 5 sub-dimensions (24 in total), and 135 performance indicators. CONCLUSIONS: The Org-HLR Tool and assessment process were developed to address a gap in available tools to support organisations to assess their health literacy responsiveness, and prioritise and plan their quality improvement activities. The tool is currently in the field for further utility and acceptability testing.

Barriers to Breast Cancer Screening among Diverse Cultural Groups in Melbourne, Australia.

This study explored the association between health literacy, barriers to breast cancer screening, and breast screening participation for women from culturally and linguistically diverse (CALD) backgrounds. English-, Arabic- and Italian-speaking women (n = 317) between the ages of 50 to 74 in North West Melbourne, Australia were recruited to complete a survey exploring health literacy, barriers to breast cancer screening, and self-reported screening participation. A total of 219 women (69%) reported having a breast screen within the past two years. Results revealed that health literacy was not associated with screening participation. Instead, emotional barriers were a significant factor in the self-reported uptake of screening. Three health literacy domains were related to lower emotional breast screening barriers, feeling understood and supported by healthcare providers, social support for health and understanding health information well enough to know what to do. Compared with English- and Italian-speaking women, Arabic-speaking women reported more emotional barriers to screening and greater challenges in understanding health information well enough to know what to do. Interventions that can improve breast screening participation rates should aim to reduce emotional barriers to breast screening, particularly for Arabic-speaking women.

Development and testing of a framework for analysing health literacy in public policy documents.

Health literacy is a driver of community empowerment and a key determinant of health and equity. The World Health Organisation has established a strong global mandate for addressing health literacy through public policy action, by positioning it as one of three key pillars for achieving sustainable development and health equity in the Shanghai Declaration on Health Promotion. Policy document analysis is a useful way of determining the strengths and limitations of past and current policies, as well as the likely success of their implementation and impact on health outcomes. In this study, we developed a framework for analysing policy documents to assess the extent to which they prioritise and operationalise an emergent public health issue, in this case health literacy. Specifically, the framework enables a systematic exploration of (i) the stated policy goals and strategic objectives; (ii) the stated policy actions; and (iii) whether there is an intention to resource and monitor the stated policy activities. We tested the utility of the framework by applying it to a set of public policies in the Australian context. The framework presented in this study may be a useful tool for systematically analysing policy documents to reveal their strengths and limitations, and the extent to which they prioritise and operationalise health literacy.

Conceptualisation and development of the Conversational Health Literacy Assessment Tool (CHAT).

BACKGROUND: The aim of this study was to develop a tool to support health workers' ability to identify patients' multidimensional health literacy strengths and challenges. The tool was intended to be suitable for administration in healthcare settings where health workers must identify health literacy priorities as the basis for person-centred care. METHODS: Development was based on a qualitative co-design process that used the Health Literacy Questionnaire (HLQ) as a framework to generate questions. Health workers were recruited to participate in an online consultation, a workshop, and two rounds of pilot testing. RESULTS: Participating health workers identified and refined ten questions that target five areas of assessment: supportive professional relationships, supportive personal relationships, health information access and comprehension, current health behaviours, and health promotion barriers and support. CONCLUSIONS: Preliminary evidence suggests that application of the Conversational Health Literacy Assessment Tool (CHAT) can support health workers to better understand the health literacy challenges and supportive resources of their patients. As an integrated clinical process, the CHAT can supplement existing intake and assessment procedures across healthcare settings to give insight into patients' circumstances so that decisions about care can be tailored to be more appropriate and effective.

Measuring cancer caregiver health literacy: Validation of the Health Literacy of Caregivers Scale-Cancer (HLCS-C) in an Australian population.

Caregivers have been largely neglected in health literacy measurement. We assess the construct validity, and internal consistency of the Health Literacy of Caregivers Scale-Cancer (HLCS-C), and present a revised, psychometrically robust scale. Using data from 297 cancer caregivers (12.4% response rate) recruited from Melbourne, Australia between January-July 2014, confirmatory factor analysis (CFA) was conducted to evaluate the HLCS-C's proposed factor structure. Items were evaluated for: item difficulty, unidimensionality and overall item fit within their domain. Item-threshold-ordering was examined though one-parameter Item Response Theory models. Internal consistency was assessed using Raykov's reliability coefficient. CFA results identified 42 poorly performing/redundant items which were subsequently removed. A 10-factor model was fitted to 46 acceptable items with no correlated residuals or factor cross-loadings accepted. Adequate fit was revealed (χ2WLSMV  = 1463.807[df = 944], p < .001, RMSEA = 0.043, CFI = 0.980, TLI = 0.978, WRMR = 1.00). Ten domains were identified: Proactivity and determination to seek information; Adequate information about cancer and cancer management; Supported by healthcare providers (HCP) to understand information; Social support; Cancer-related communication with the care recipient (CR); Understanding CR needs and preferences; Self-care; Understanding the healthcare system; Capacity to process health information; and Active engagement with HCP. Internal consistency was adequate across domains (0.78-0.92). The revised HLCS-C demonstrated good structural, convergent, and discriminant validity, and high internal consistency. The scale may be useful for the development and evaluation of caregiver interventions.
