Hearing and vision impairments are common globally. They are often considered separately in research, and in planning and delivering services. However, they can occur concurrently, termed dual sensory impairment (DSI). The prevalence and impact of hearing and vision impairment have been well-examined, but there has been much less consideration of DSI. The aim of this scoping review was to determine the nature and extent of the evidence on prevalence and impact of DSI. Three databases were searched: MEDLINE, Embase and Global Health (April 2022). We included primary studies and systematic reviews reporting the prevalence or impact of DSI. No limits were placed on age, publication dates, or country. Only studies where the full text was available in English were included. Two reviewers independently screened titles, abstract, full texts. Data were charted by two reviewers independently using a pre-piloted form. The review identified 183 reports of 153 unique primary studies and 14 review articles. Most evidence came from high-income countries (86% of reports). Prevalence varied across reports, as did age groups of participants and definitions used. The prevalence of DSI increased with age. Impact was examined across three broad groups of outcomes—psychosocial, participation, and physical health. There was a strong trend towards poorer outcomes for people with DSI across all categories compared to people with one or neither impairment, including activities of daily living (worse for people with DSI in 78% of reports) and depression (68%). This scoping review highlights that DSI is a relatively common condition with substantial impact, particularly among older adults. There is a gap in evidence from low and middle-income countries. There is a pressing need for a consensus position on the definition(s) of DSI and standardisation of reporting age groups to enable reliable estimates to be ascertained and compared and responsive services developed.

The increasing burden of chronic diseases, and shortage of health care workers especially in Low and Middle Income countries (LMICs) requires greater collaborative working between health professions. There is a growing body of evidence that interprofessional education (IPE) and interprofessional continuous education (IPCE) can improve collaborative practice thus strengthening health care delivery in low resource settings. The World Health Organization (WHO) promotes this educational strategy in these regions as part of wider programs to improve health care. The purpose of this systematic review was to summarize IPE and IPCE activities in sub-Saharan Africa (SSA) and its outcomes; including practice, service and patient outcomes. Standard guidelines for conducting and reporting systematic reviews were followed. The online databases searched included MEDLINE, Embase, Education Resources Information Centre (ERIC), the Cumulative Index of Nursing and Allied Health Literature (CINAHL) and Science Direct. The Kirkpatrick model was used to classify IPE outcomes reported from literature. Following full text screening, 41 articles were selected for data extraction. It was found that IPE/IPCE is still a relatively new concept in SSA with 93% of studies published after 2012. Furthermore, IPE is concentrated predominantly in undergraduate institutions and mainly implemented to improve collaborative practice and address important public health concerns. Positive reaction and outcomes of IPE/IPCE were reported in terms of change of attitude and perception toward collaborative practice as well as knowledge and skills acquisition. Few studies in SSA sought to understand and measure the outcomes of IPE/IPCE relating to health care practice. More work in this important potential outcome of IPE/IPCE is recommended.

Introduction: Driving is one of the main modes of transport with safe driving requiring a combination of visual, cognitive and physical skills. With population ageing, the number of people living with vision impairment is set to increase in the decades ahead. Vision impairment may negatively impact an individual’s ability to safely drive. The association between vision impairment and motor vehicle crash involvement or driving participation has yet to be systematically investigated. Further, the evidence for the effectiveness of vision-related interventions aimed at decreasing crashes and driving errors has not been synthesised. Methods and analysis: A search will be conducted for relevant studies on Medline (Ovid), EMBASE and Global Health from their inception to March 2020 without date or geographical restrictions. Two investigators will independently screen abstracts and full texts using Covidence software with conflicts resolved by a third investigator. Data extraction will be conducted on all included studies, and their quality assessed to determine the risk of bias using the Joanna Briggs Institute Critical Appraisal Tools. Outcome measures include crash risk, driving cessation and surrogate measures of driving safety (eg, driving errors and performance). The results of this review will be reported using the Preferred Reporting Items for Systematic Review and Meta-Analysis guideline. Meta-analysis will be undertaken for outcomes with sufficient data and reported following the Meta-analyses of Observational Studies in Epidemiology guideline. Where statistical pooling is not feasible or appropriate, narrative summaries will be presented following the Synthesis Without Meta-analysis in systematic reviews guideline. Ethics and dissemination: This review will only report on published data thus no ethics approval is required. Results will be included in the Lancet Global Health Commission on Global Eye Health, published in a peer-reviewed journal and presented at relevant conferences.

Preventable and treatable visual impairment affects more than 1 billion people worldwide. Rwanda has an estimated visual impairment prevalence of 3.7% amongst the 12 million inhabitants. Around one third of this demand could be addressed through a more integrated and collaborative approach, particularly in primary eye care services. Healthcare students, therefore, need to be prepared for collaborative practice in eye health through interprofessional learning. Interprofessional workshops were piloted with ophthalmic clinical officer, medical clinical officer, nursing and medical students from the University of Rwanda. The aim was to promote collaborative practice by teaching students how to assess and recognize common eye conditions using the Arclight; a low cost, solar powered, portable ophthalmoscope designed for use in low resource settings. Students reported that the workshop content was relevant to all professional groups. They valued the opportunity to learn interprofessionally, share their knowledge and perspectives, and acquire new knowledge and skills together. This pilot helped to identify the most relevant skills and knowledge for future interprofessional eye health training. It enabled the facilitators to reflect on how best to maintain a balance between a quality interprofessional experience and the more specific eye health related learning objectives.

Visual impairment and blindness affect an estimated 2.2 billion people worldwide. Accessible low-cost diagnostic tools and interprofessional education and collaborative practice are part of ongoing strategies to improve eye care services. This study evaluated the impact of an interprofessional Arclight workshop on undergraduate healthcare students’ clinical identification skills related to eye health, and self-reported confidence in ophthalmic skills. Undergraduate students from clinical medical officer, ophthalmic clinical officer, Bachelors and Diploma nursing, and medical programs at the University of Rwanda participated in a pilot interprofessional eye health workshop. The Arclight device, a low-cost ophthalmoscope and simulation eyes were used to enable students to practice ophthalmic skills and thereafter equip them. Clinical identification skills related to common eye conditions, and self-reported confidence in ophthalmic skills were assessed pre and post workshop. Overall, students’ ability to identify common eye conditions, and self-reported confidence in relation to all skills statistically improved post workshop, with some differences between professional groups in relation to eye health skills. This IPE experience used the Arclight package as a vehicle for IPE, enabling healthcare students to share and acquire new skills and confidence in relation to recognizing common eye conditions and assessing eye health.

The aim of this study was to investigate barriers and enablers associated with the uptake of cataract surgery in Rwanda, where financial protection is almost universally available. This was a hospital-based cross-sectional study where potential participants were adults aged >18 years who accepted an appointment for cataract surgery during the study period (May–July 2019). Information was collected from hospital records and a semi-structured questionnaire was used for data collection. Of the 297 people with surgery appointments, 221 (74.4%) were recruited into the study, 126 (57.0%) of whom had attended their appointment. People more likely to attend their surgical appointment were literate, had fewer than 8 children, had poorer visual acuity, had access to a telephone in the family, received a specific date to attend their appointment, received a reminder, and reported no difficulties walking (95% significance level, p < 0.05). The most commonly reported barriers were insufficient information about the appointment (n = 40/68, 58.8%) and prohibitive indirect costs (n = 29/68, 42.6%). This study suggests that clear communication of appointment information and a subsequent reminder, together with additional support for people with limited mobility, are strategies that could improve uptake of cataract surgery in Rwanda.
