Evidence-based preschool-age vision screening: health policy considerations.

ABSTRACT:

Background

There are many causes of visual impairment, and even blindness, which are treatable or at least preventable. Two such conditions are strabismus (crossed-eye, squint) and refractive error (visual image not focused on the most sensitive part of the retina). If these are not detected and corrected at an early age, they can lead to an irreversible impairment known as amblyopia (lazy eye). Pediatric vision screening and subsequent treatment for amblyopia and amblyogenic risk factors are thus key to preventing vision loss. Furthermore, vision screening can detect moderate to high hyperopia, which has been found to be associated with poor school readiness. Evidence-based recommendations call for screening children at 3-5 years of age; they are old enough to cooperate, but still within the window of effective intervention. However, these recommendations have yet to be universally implemented as the standard of care.

Methods

This paper integrates a review of the literature and the international experience of preschool vision screening with the findings from a preliminary feasibility study of expanded screening in Israel to formulate a discussion of the current health policy challenge in Israel and the options for addressing it. The advantages and disadvantages of various venues for vision screening are discussed.

Findings

Screening by optometrists in Mother and Child Health Centers, as implemented in a recent pilot project in the Jerusalem District, would allow the most comprehensive testing. Photo-screening in preschools would reach the most children, but at the cost of missing hyperopia (farsightedness). Either approach would probably constitute improvements over the current situation. The relative strengths of the two approaches depends in part on the ability to purchase automatic screening equipment (and the efficacy of that equipment) vs. the ongoing cost of paying trained personnel.

Conclusions

Further research should be conducted in Israel to determine the prevalence of refractive errors, so that best practices can be established for Israel's population and social needs. In the interim, the Ministry of Health should promptly implement the inclusion of preschool visions screening for children in the approved "basket of services" covered by the National Health Insurance Laws, using photo-screening, including collection of the clinical data.

Project description:UnlabelledBackgroundThe 58th World Health Assembly and 56th WHO Regional Committee for Africa adopted resolutions urging Member States to ensure that health financing systems included a method for prepayment to foster financial risk sharing among the population and avoid catastrophic health-care expenditure. The Regional Committee asked countries to strengthen or develop comprehensive health financing policies. This paper presents the findings of a survey conducted among senior staff of selected Eritrean ministries and agencies to elicit views on some of the elements likely to be part of a national health financing policy.MethodsThis is a descriptive study. A questionnaire was prepared and sent to 19 senior staff (Directors) in the Ministry of Health, Labour Department, Civil Service Administration, Eritrean Confederation of Workers, National Insurance Corporation of Eritrea and Ministry of Local Government. The respondents were selected by the Ministry of Health as key informants.ResultsThe key findings were as follows: the response rate was 84.2% (16/19); 37.5% (6/16) and 18.8% said that the vision of Eritrean National Health Financing Policy (NHFP) should include the phrases 'equitable and accessible quality health services' and 'improve efficiency or reduce waste' respectively; over 68% indicated that NHFP should include securing adequate funding, ensuring efficiency, ensuring equitable financial access, protection from financial catastrophe, and ensuring provider payment mechanisms create positive incentives to service providers; over 80% mentioned community participation, efficiency, transparency, country ownership, equity in access, and evidence-based decision making as core values of NHFP; over 62.5% confirmed that NHFP components should consist of stewardship (oversight), revenue collection, revenue pooling and risk management, resource allocation and purchasing of health services, health economics research, and development of human resources for health; over 68.8% indicated cost-sharing, taxation and social health insurance as preferred revenue collection mechanisms; and 68.75% indicated their preferred provider payment mechanism to be a global (lump sum) budget.ConclusionThis study succeeded in gathering the preliminary views of senior staff of selected Eritrean ministries and agencies regarding the likely elements of the NHFP, i.e. the vision, objectives, components, provider payment mechanisms, and health financing agency and its governance. In addition to stakeholder surveys, it would be helpful to inform the development of the NHFP with other pieces of evidence, including cost-effectiveness analysis of health services and interventions, financial feasibility analysis of financing options, a survey of the political and professional acceptability of financing options, national health accounts, and equity analyses.

Project description:BackgroundThe use of information and communication technologies (ICTs) to deliver mental health and addictions (MHA) services is a global priority, especially considering the urgent shift towards virtual delivery of care in response to the COVID-19 pandemic. It is important to monitor the evolving role of technology in MHA services. Given that MHA policy documents represent the highest level of priorities for a government's vision and strategy for mental health care, one starting point is to measure the frequency with which technology is mentioned and the terms used to describe its use in MHA policy documents (before, during, and after COVID-19). Yet, to our knowledge, no such review of the extent to which ICTs are referred to in Canadian MHA policy documents exists to date.ObjectiveThe objective of this systematic policy review was to examine the extent to which technology is addressed in Canadian government-based MHA policy documents prior to the COVID-19 pandemic to establish a baseline for documenting change.MethodsWe reviewed 22 government-based MHA policy documents, published between 2011 and 2019 by 13 Canadian provinces and territories. We conducted content analysis to synthesize the policy priorities addressed in these documents into key themes, and then systematically searched for and tabulated the use of 39 technology-related keywords (in English and French) to describe and compare jurisdictions.ResultsTechnology was addressed in every document, however, to a varying degree. Of the 39 searched keywords, we identified 22 categories of keywords pertaining to the use of technology to deliver MHA services and information. The 6 most common categories were tele (n=16/22), phone (n=12/22), tech (n=11/22), online (n=10/22), line (n=10/22), and web (n=10/22), with n being the number of policy documents in which the category was mentioned out of 22 documents. The use of terms referring to advanced technologies, such as virtual (n=6/22) and app (n= 4/22), were less frequent. Additionally, policy documents from some provinces and territories (eg, Alberta and Newfoundland and Labrador) mentioned a diverse range of ICTs, whereas others described only 1 form of ICT.ConclusionsThis review indicates that technology has been given limited strategic attention in Canadian MHA policy. Policy makers may have limited knowledge on the evidence and potential of using technology in this field, highlighting the value for knowledge translation and collaborative initiatives among policy makers and researchers. The development of a pan-Canadian framework for action addressing the integration and coordination of technology in mental health services can also guide initiatives in this field. Our findings provide a prepandemic baseline and replicable methods to monitor how the use of technology-supported services and innovations emerge relative to other priorities in MHA policy during and after the COVID-19 pandemic.
