Universal access to essential health information: accelerating progress towards universal health coverage and other SDG health targets

•,,.

...

Abstract

The information that people need to protect and manage their own health and the health of those for whom they are responsible is a fundamental element of an effective people-centred healthcare system. Achieving universal health coverage (UHC) requires universal access to essential health information. While it was recently recognised by the World Medical Association, universal access to essential health information is not yet reflected in official monitoring of progress on UHC for the sustainable development goals (SDGs). In this paper, we outline key features that characterise universal access to essential health information and indicate how it is increasingly achievable. We highlight the growing evidence of the impact of wider access to practical and actionable information on health for the public, carers and frontline health workers and provide illustrative, evidence-based, examples of how increasing access to essential health information can accelerate the achievement of UHC and other health targets of the SDGs. The paper ends with an assessment of reasons why universal access to essential health information has not yet been achieved, and an associated call to action to key stakeholders—such as governments, multilaterals, funding bodies, policy-makers, health professionals and knowledge intermediaries—to explicitly recognise the foundational role of universal access to essential health information for achieving UHC and the rest of the health SDGs, to include it in the relevant SDG target and associated monitoring indicators, and to incorporate actions in their own policies and programmes to promote and enable this access.

Summary box

Effective people-centred healthcare requires the public, carers and frontline health workers to have timely access to reliable, practical, health information (we term this essential health information), yet in many parts of the world this is often difficult for people to obtain.
Universal access to essential health information is therefore a prerequisite for, and indeed a key component of, universal health coverage (UHC), yet this fundamental role for UHC of access to essential health information appears to have been largely neglected—for example, it does not feature in the sustainable development goal (SDG) UHC target or associated indicators.
There is growing evidence of the impact of wider access to practical, actionable, information about health and how this could accelerate the achievement of UHC and other SDG health targets.
Achieving universal access to essential health information is becoming increasingly feasible and affordable, not least due to the global spread of modern communication technology, but progress is being held back by a glaring lack of high-level political and financial commitment.
All stakeholders need to work together to accelerate progress towards universal access to essential health information; a catalyst for this would be the inclusion of universal access to essential health information in the relevant SDG target and associated monitoring indicators for UHC, a step that WHO could usefully endorse.

Introduction

The protection of the health of any individual or population, including the prevention and appropriate management of disease, is fundamentally dependent on the availability and use of reliable health information (see figure 1). (Although ‘health information’ is sometimes used to refer to data only, especially that used by managers and policy-makers, in this paper health information refers to practical information, especially that used by the public and health workers, for health and healthcare.)

The fundamental role of information and knowledge in a person’s health pathway.

The need to improve individuals’ access to health information, to give better support to people-centred care, is indicated by recent statements by international bodies, for example, the UNICEF/WHO Vision for Primary Health Care in the 21st century1 includes the aim that ‘People have access to the knowledge, skills and resources needed to care for themselves and their loved ones’. That requires the public, carers and frontline health workers to have timely access to reliable, practical, actionable, health information.

We term this essential health information—the information that people need to protect their own health and the health of those for whom they are responsible. It includes information and knowledge to promote health and to prevent, diagnose and manage disease and injury. It acknowledges that, especially in low-income and middle-income countries, most avoidable mortality and morbidity can be prevented through the application of basic health knowledge (eg, on using amoxicillin for child pneumonia; on the need for oral rehydration for acute diarrhoea; about healthy lifestyle choices to prevent cardiovascular disease, cancer, respiratory disease and diabetes). See table 1.

Table 1

Characteristics of essential health information

Given the key role of such information for health, the Healthcare Information For All network (HIFA) has argued,2 and the World Medical Association has recently issued a supportive statement,3 that universal access to essential health information is a prerequisite for universal health coverage (UHC). Indeed, from a ‘whole system’ perspective—explicitly a key feature of the sustainable development goals (SDGs)—it should be seen as a key component of UHC. Such access is therefore also a prerequisite for attaining the SDG on health (SDG3) and associated targets, especially of course the UHC target (SDG 3.8 ‘Achieve universal health coverage, including financial risk protection, access to quality essential health-care services and access to safe, effective, quality and affordable essential medicines and vaccines for all’.)

Evidence of the impact of wider access to health information

A government survey, published in 2006,4 found that only 4 in 10 children in India received any form of oral rehydration therapy (ORT) if they developed diarrhoea. Areas where knowledge of ORT was greater tended also to be to those where its use was greater. The next national survey, in 2015,5 showed that more women in India knew about ORT than before and the proportion of children with diarrhoea who received it had now risen to 6 in 10. Other investigations also have indicated positive impacts from the provision of information about appropriate care in such cases; for example, use of the HealthPhone mobile app has been associated with improvements in increased use of oral rehydration during diarrhoea episodes, and of increased frequency of handwashing, breast feeding and immunisation.6

There are now an increasing number of evaluations and, more recently, reviews of evaluations, being published on the impact of making essential health information more accessible, especially via mobile phones, for example.7 Impact studies in LMICs, at least for mHealth, are increasing and there are now several systematic reviews of mHealth in areas such as maternal and neonatal care,8 9 and non-communicable diseases and public health.10 11 Many of these studies focus on provision of health information.

Drawing on the development of such evidence, WHO has recently published guidance12 on use of digital interventions, including those providing health information, and made recommendations including one specifically relating to information provision for the public and carers: “WHO recommends targeted client communication via mobile devices for behaviour change regarding sexual, reproductive, maternal, newborn and child health, under the condition that concerns about sensitive content and data privacy are adequately addressed” (p59).

Of course, not all evaluations in this area reveal positive results. For example, some trials of text messaging have not shown any impact on health-related behaviour, see, for example, Linnemayr et al.13 But there are many examples of success, indicating considerable potential for wider access to essential health information to contribute to progress on SDG health targets. Some specific evaluated examples are given in the next section.

Universal access to essential health information and progress on UHC and other SDG health targets

The world faces a major challenge in meeting the SDG targets, not least the SDG 3.8 target for UHC by 2030, which WHO estimates (WHO General Work Programme 2019–2023 para 32) will require a doubling or tripling of the current pace of change.

Universal access to essential health information is an important component of the package of measures that will be necessary to increase the pace of change towards UHC and other SDG3 targets. Access to essential health information can be an accelerator for many of the components of UHC monitored for SDG 3.8.1, other SDG3 health targets and health literacy.

This key point is developed and illustrated in tables 2 and 3.

Table 2

Examples of practical health information relevant to target areas in the UN monitoring framework for universal health coverage (UHC)

Table 3

Illustrative examples of the potential contribution of access to essential health information to achieving sustainable development goal (SDG3) health targets

The first column of table 2 shows the framework,14 comprising a set of areas of health, currently being used or considered for use by the UN to monitor progress towards UHC. Progress in most if not all of these areas would be supported by universal access to essential health information. For example, enhancement of care-seeking rates in pregnancy and childhood illness, by families having access to information on when and how care should be sought. We give further examples in the second column of table 2. We chose these examples not least because all of this information, and more, in many LMICs, already exists, though often is not yet widely accessible, in traditional or digital media.

In table 3, we provide documented evidence-based illustrations of how provision of practical health information in the target areas described in table 2 can contribute to achieving the SDG3 targets on specific health issues and progress towards UHC as monitored by the associated SDG indicators.

Lack of access to essential health information is a neglected issue in the SDG UHC target

Unfortunately, in many parts of the world, it is often difficult for people to obtain essential health information. This needs to be accessible:

to the relevant person (eg, individual, carer or frontline health worker),
in a given location (eg, a remote village),
at the time it is most needed (eg, an emergency),
through a suitable medium (eg, print, radio, TV, phone, internet),
at an affordable (preferably zero) cost.

Despite the importance of access to such information, and hence of addressing the challenges of lack of access, this does not feature in the SDG target on UHC or the associated current set of indicators15 for assessing progress towards the target. (It is mentioned only in relation to one specific aspect of healthcare in a related target (SDG 3.7) “ensure universal access to sexual and reproductive health-care services, including for family planning, information and education…”).

As noted16 by HIFA, the UHC target (SDG 3.8) could be made more consistent with current WHO policies and guidelines on primary care by adding just two words (shown in bold) to it, that is: “Achieve universal health coverage, including financial risk protection, access to quality essential health-care services [and information], and access to safe, effective, quality and affordable essential medicines and vaccines for all”; and to similarly include “access to essential health information” in the corresponding monitoring indicator (SDG 3.8.1)

The current omission of access to essential health information from the SDG UHC target has important practical consequences. First, and directly, it inhibits the development of the tools and indicators needed to measure progress in expanding the access to and use of essential health information. Second, and fundamentally, it misses an opportunity to give international impetus to improving access to essential health information at global, national and local levels. This is especially needed in LMICs, to ensure that frontline health workers are adequately informed and that people are empowered with the knowledge they need to be active in their own health.

Achieving universal access to essential health information is increasingly feasible

Access to health information depends on the workings of the global health information system, that is, the system by which reliable health information is created, (re)packaged and then made available, as outlined in figure 2, and how this plays out in different settings.

There are now major opportunities for improving this system, not least for improving access to reliable, practical, health information that already exists. There is now a range of simple, affordable and scalable17 routes for widening such access.

First, traditional routes of getting health information into the hands of those who most need it, typically through printed (for example, the guide Where there is No Doctor18), or other long-established media, for example, radio and film. Indeed, radio messaging has been part of the public health armoury for decades, and organisations such as Medical Aid Films19 and Global Health Media20 have been producing open access audio and video content in local languages, in collaboration with international health organisations such as WHO and UNICEF, for many years. The reach of these now extends to films on a wide range of topics (such as nutrition, pregnancy, newborn care, child health, infectious diseases like cholera or Ebola), in dozens of languages, available in hundreds of countries, with millions of views each year.

Second, the digital revolution offers huge potential to advance access to essential health information, among a range of contributions towards UHC.21 On 26 May 2018, “recognizing the potential of digital technologies to advance the Sustainable Development Goals”, the World Health Assembly passed a resolution on Digital Health (A71-R7) urging Member States “to prioritize, as appropriate, the development, evaluation, implementation, scale-up and greater utilization of digital technologies, as a means of promoting equitable, affordable and universal access to health for all”.

Multiple digital routes are opening up to provide this access. For example, WikiMed provides free, offline, digital access, for example, on laptops, tablets or mobile phones, to all of Wikipedia’s health content. Of particular importance for the public and carers is access to health information through mobile phones22 which are now ubiquitous, not least in LMICs (as the WHO Vision for Primary Care in the 21st Century, page 21, notes: “Today … the first thing that many people across the world do when faced with a health problem is to use their mobile phone to seek more information”) . For example:

For people with access to basic phones: SMS texting, such as in the MomConnect maternal health service used by 2 million women in South Africa,23 is already a well-established pathway for ‘provider push’ distribution of health messages. Essential health information can also be provided through ‘user pull’ pathways (such as free or subsidised voice-on-demand services) which empower the public and carers to get the health information they want, in a form they can use, when and where they need it. These services respond with (usually prerecorded) audio messages in local languages to user requests for health information on a range of key heath topics. A few organisations already provide such services (eg, 3-2-1 (Viamo/Human Network International),24 Mobile Kunji (BBC Media Action).25
For (the rapidly increasing number of) people with access to feature or smartphones: essential health information for the public and carers can be provided in a user pull mode through mobile ‘apps’, many of which, once downloaded, will function even without a network connection. Such applications often include short practical ‘how to’ videos that are accessible to all irrespective of literacy level. Notable examples (and the organisations that produce them) include: First Aid (Red Cross),26 HealthPhone (Mother and Child Trust)27; Safe Pregnancy and Birth (Hesperian—publisher of Where There is No Doctor).28

A call to action

Why have we not achieved universal access to essential health information? There are at least two reasons. The first is that there is no single fix, no ‘magic bullet’. As previously described,29 the availability and use of reliable health information are dependent on the integrity of the global health information system. A systems-thinking approach to the issue readily demonstrates the vital inputs of a huge number and diversity of ‘components’, including health research per se, publication and dissemination of such research, systematic review, guideline development and the myriad of different secondary outputs for end-users.

However, there are important system leverage points,30 one of which (a focus of this paper) is improving access to reliable, practical health information that already exists. The second reason is related to the first: lack of recognition by governments and funding agencies of the fundamental importance of access to essential health information, and consequent lack of investment.

We therefore call on all stakeholders—including governments, multilaterals (WHO, World Bank, UNESCO, UNICEF, International Labour Organization, International Telecommunication Union and others), funding bodies, policy-makers, health professionals and knowledge intermediaries—to work together to accelerate progress towards universal access to essential health information.

This could include assessing, in each country, the level of access, by traditional and by digital pathways, to essential health information; agreeing, steps, appropriate to that country, that could be best taken rapidly to increase such access; and then actioning them. (This could be stimulated by adding access to essential health information to the UHC target (SDG3.8) and/or to the corresponding monitoring indicator (SDG3.8.1) for service coverage, a step that WHO could usefully endorse.)

In the past 20 years, WHO has led and enabled a number of important initiatives, such as the Hinari Access to Research in Health Programme, to improve the availability of health information. It is uniquely placed to facilitate further action over the years to come. In 2006, WHO wrote a letter of support for the launch of the global campaign, HIFA (www.hifa.org), which stated: “Healthcare Information For All is an ambitious goal, but it can be achieved if all stakeholders work together”. We, together with the 20 000 members of HIFA, representing all stakeholder groups in almost every country, and working in formal collaboration with WHO to support global health communication in multiple languages, look forward to continue working with WHO and others to make universal access to essential health information a reality.

Conclusion

We have argued that universal access to essential health information is a prerequisite for, and indeed a component of, UHC and have presented illustrative examples as evidence of how enhancing such access can serve as an accelerator for achieving UHC and the other health SDGs. We have argued that universal access is not only necessary, but is increasingly feasible and affordable, not least because of advances in communication technology: what has been termed the 15th Grand Challenge for Global Health—‘to ensure that everyone in the world can have access to clean, clear, knowledge’31—is well within reach. (We note also that governments that are party to treaties such as the International Covenant on Civil and Political Rights, that is, almost all governments, ‘must provide and guarantee access to health information’.32) However, we have also noted that overall progress is being held back by a glaring lack of high-level political and financial commitment.
