Ethics should be an integral part of the design and deployment of a digital solution. However, policy decisions are often complex and difficult. Many different considerations will need to be made and weighed against each other. Often, the evidence is uncertain and there are many different competing ethical perspectives and positions. Evidence alone will not provide the right answer, nor will a simple set of ethical rules. Public health action requires careful judgement and acceptance of responsibility for the outcomes. A number of different ethical considerations should be taken into account, including both objectives and processes.
A good starting point is to identify how the use of a digital solution can contribute to important general duties of any government through public health. Three key objectives of public health action are:
The creation and use of a digital solution can contribute to each of these objectives. For example, in relation to objective 1, a digital solution can promote welfare through the provision of digital health records enabling continuity of care by ensuring that individuals have access to their health data across facilities. Promotion of this objective also contributes to confidence in the health infrastructure of the government, benefitting the whole population. Such an outcome is an important common good – that is, a good for all that cannot be created by each individual alone. Such goods require the coordinated actions of, and support from, governments. In addition, other benefits will follow from the use of a digital solution, because of improved health and subsequent increased opportunities for individuals and communities to make their own choices and pursue their own economic and social goals. In relation to objective 2, equal treatment requires respecting and protecting all persons equally and acting to ensure, as far as possible, that there is no discrimination against anyone. An example of how to work towards this objective is to ensure that appropriate personal data protection safeguards are implemented. Individual health data is private information, and protections need to be in place to ensure that no individual is forced to disclose or publicly display their personal health record (PHR) to access any public area or activity (1). Such a practice and/or the lack of a PHR itself may result in the stigmatization of individuals without a PHR and may exacerbate the risk of harms. Another example of working towards objective 2 is to think about ways to try and achieve equity through the distribution of health resources. While a digital solution may offer a more reliable, accurate and trusted mechanism to record an personal health history, they risk exacerbating health inequities, for the following reasons.
→ A PHR may increase digital exclusion if its application and use and requires that individuals have access to a digital infrastructure or if that digital infrastructure is too burdensome for all Member States to deploy.
→ Individuals with geographical, financial or disability barriers may also be excluded from obtaining and using a PHR, depending on the administration process, cost and design. Ensuring an equitable and inclusive approach to the implementation of a digital solution will mean that those with greater barriers to obtaining and using a PHR are supported to a greater extent than others.
In relation to objective 3, trust is vital to ensuring the benefits of a digital solution for individuals, communities and the whole population. For example, the provision of robust data protection measures and the use of procedural considerations, outlined in section 1.3.4, may contribute to the maintenance of trust in public health systems. This in turn contributes to the delivery of objective 1. Another example might be that a digital solution should only be used for its intended purpose, as inappropriate uses may result in legitimate ones being undermined.
The pursuit of the objectives above can create ethical problems. One way to mitigate this risk is by ensuring that various processes uphold important procedural values. These values, in turn, also contribute to the pursuit of the objectives above. Such values include:
→ TRANSPARENCY: providing clear, accurate and publicly accessible information about the basis for the policy and the process by which it is made, from the onset – i.e. notifying the public that such a process is underway. Such a process disciplines decision-making and ensures accountability by providing a sound basis for an eventual decision that reasonable members of the public may agree with.
→ INCLUSIVENESS IN DECISION-MAKING: providing opportunities for all relevant stakeholders to participate in policy formulation and design, in particular those affected, and advocates for these individuals and groups.
→ ACCOUNTABILITY: providing a clear framework for who is responsible for what, and how responsibilities will be regulated and enforced.
→ RESPONSIVENESS: providing mechanisms and opportunities to review and revise decisions and policies based on evolving scientific evidence and other relevant data. This may include public consultation or engagement with a wide range of experts, industries and other stakeholders so that the policies are responsive to real and perceived ethical issues and concerns. Particularly important stakeholders are those who are likely to be disadvantaged or face distinct or heightened risks with the creation of a PHR, such as individuals who are unable or unwilling to create a PHR, i.e. individuals with insecure or invalid citizenship or residency status, and individuals who may face other barriers in obtaining or using a PHR (2).
A number of further possible uses for digital PHRs raise ethical issues. In the context of a public health emergency, a digital PHR might play a role in achieving various public health purposes such as determining vaccination coverage in a given population, which may help to determine when to lift or relax public health and social measures (PHSMs) at a population level. A digital PHR might also be used to facilitate individualized exemption from, or, reduction of PHSMs (e.g. reduced quarantine time post exposure) or individual access to an activity based on proof of vaccination (if such uses are held to be ethical), which we can term a “health pass” function. The potential deployment or utilization of a digital PHR for these purposes, particularly as a health pass, engenders a number of potential ethical problems for individuals and communities, and human rights challenges (3,4).
First, use of a digital PHR as a health pass raises a distinct set of risks because of current scientific uncertainties emergent diseases. For example, during the COVID-19 Public Health Emergency of International Concern (PHEIC), COVID-19 vaccines have demonstrated efficacy and effectiveness in preventing severe disease and death, the extent to which each vaccine prevents transmission of SARS-CoV-2 to susceptible individuals were not fully assessed. How long each vaccine confers protection against severe disease and against infection, and how well each protects against current and future variants of SARS-CoV-2 were not fully known. In this context of scientific uncertainty, use of a digital PHR as a health pass based solely on individual vaccination status may increase the risk of disease spread. This is particularly the case if individuals with a digital PHR are completely exempted from PHSMs or if it is hard to enforce individuals’ compliance with required
PHSMs during an activity (e.g. mask wearing and physical distancing during a concert) to which they are allowed access based on their digital PHR.
Second, some potential behavioural responses to a digital PHR in its role as a health pass could undermine individual and public health. These include the following.
→ Where the benefits of a health pass are significant, it may result in digital PHR fraud. For example, fraudulent vaccination records may increase public health risks if a non-vaccinated person is potentially in contact with vulnerable people.
→ Individuals may be less willing to disclose their medical history and (potential) contraindications to a public health intervention (e.g. vaccine), in order to obtain a corresponding digital PHR, which increases the risk of adverse events.
→ The creation of a digital PHR following vaccination for each individual may incentivize more people to participate in a public health measure (e.g. receive a vaccine) to access the benefits of a digital PHR. However, it may also increase hesitancy to participate in the public health measure because of privacy and other concerns that the vaccination record could be linked to personal data and be used for functions other than those originally intended (e.g. surveillance of individual health status), or be used by unintended third parties (e.g. immigration, commercial entities, researchers) (5).
Third, a digital PHR in its use as a health pass risks introducing unfair disadvantages and injustices. For example, during the COVID-19 PHEIC, the initially limited supply of COVID-19 vaccine within some countries had been distributed to prioritize those at greatest risk of infection (such as health-care workers) or severe outcomes (such as the elderly). There is a danger that those who are willing to be vaccinated but have not yet been offered a vaccine, or those who are unable to be vaccinated for medical reasons, would be unfairly disadvantaged if a digital PHR incorporated health pass functions. Consideration should be given to whether individuals could use other proofs of health status to allow them similar access to the same services while mitigating the risk of disease spread. For example, during the COVID-19 PHEIC, these other proofs may have included a negative COVID-19 test or proof of post-infection-acquired immunity based on tests that are reliable and accurate (which have been called immunity certificates), although this also raises considerable scientific and ethical concerns (6).
The design, development and implementation of a digital solution raises many ethical issues. The following series of recommendations can be reviewed when considering such an implementation.
Each Member State that introduces a digital solution should be clear about which uses are proposed and that it should not be used for other purposes. To prevent any potential misuse, any digital solution implementation should set out clear and specific policies, and laws if needed, on the limits to the solutions’ legitimate uses . Use of a digital solution to restrict the right to freedom to movement and other human rights is only justified when it supports the pursuit of a legitimate aim during a public health emergency and is provided for by law, proportionate, of limited duration, based on scientific evidence, and not imposed in an arbitrary, unreasonable or discriminatory manner.
The creation or development of a digital solution should be based on an assessment of the benefits and costs of its uses, and the advantages and disadvantages of the proposed infrastructure, in comparison with other potential or existing ways to record, validate and verify vaccination records. Benefit and cost assessment – as a function of stewardship of scarce public health resources – should take short-, medium- and long-term views. A short-term view would consider the utility and opportunity cost of investing in a digital infrastructure over other measures for responding to emergencies and meeting other public health needs during a public health crisis. Consideration should be given to whether the digital infrastructure could hinder the public health response because of the potential inefficiencies it may introduce for processing registrations and/or trainings etc . A long-term view would consider the potential advantages of a digital solution for strengthening the health system, such as enhancing the health information system and its interoperability across jurisdictions. In addition, the ethical issues and risks raised by a digital solution, and the impact of trade-offs between the benefits and burdens accrued to individuals, families, businesses and other relevant stakeholders should be assessed prior to implementation. Community engagement, particularly with representatives of groups who are likely to face increased disadvantages or risks, should also be conducted.
Digital solutions should be as inclusive as possible and should not create disadvantage. To achieve this, it may be necessary to provide alternative, cost-effective solutions, including paper-based alternatives, for individuals and groups with existing disadvantages, such as those with digital skill or disability barriers, those living in areas with poorer digital connectivity, and undocumented or irregular migrants. No one should be excluded through a requirement for individual payment to obtain and use a digital solution.
A digital solution will include potentially sensitive data relating to the health of individuals, and this data should therefore be protected by appropriate medical confidentiality and privacy safeguards. Access to or use of the data for continuity of care should be based on the appropriate consent standard (e.g. implied or explicit) in a given health-care system and should be sufficient for the receiving health-care provider or team to continue providing good medical care. These ethical standards will also apply to international transfer of data for continuity of care (such as when a patient accesses medical services abroad). For adults without decisional capacity, use of their personal health records for decisions relating to their health care may be based on their advance decisions or, in the absence of an advance decision, be made in the adult’s best interest by a health-care proxy or an authorized surrogate. Minors with sufficient intelligence and maturity should be able to allow the use of their health record data for continuity of care, where consent is required.
Implementation details of a digital solution relevant to users should be communicated in a transparent manner, which may contribute to the promotion of public trust and acceptance of the solution. This communication includes how the solution would work to benefit individuals and public health, the policies and mechanisms in place to limit access to and use of the solution by third parties, whether personal health data are linked to other types of data and the purposes of any data linkage. If, in the future, the uses of the solution are extended into other scientific or public health purposes (e.g. programme monitoring or research), data subjects and other members of the public should be informed of the nature and occurrences of these activities in advance, the ethics oversight or governance structure in place (including for surveillance activities (7)), and options for controlling or limiting personal health data for these uses. personal health data are sensitive and should, in general, be anonymized (or pseudonymized, or de-identified) for scientific or public health purposes, to minimize risks to the data subjects. Where personal health data need to be retained in an identifiable form for these purposes, consideration should be given to whether consent is required or should be waived based on satisfaction of appropriate ethical criteria (e.g. minimal risk, impracticability of obtaining consent, no adverse effects on the rights and welfare of the data subjects, and serving a public health good).
Post implementation, it is important to monitor the effects of digital solution in terms of positive and negative outcomes (e.g. impact on equity) and to consider potential interventions to mitigate negative outcomes. Such monitoring should also review uses that do not fit neatly into legitimate and illegitimate use categories set by policies, to consider whether these uses should be continued, modified or stopped.
This section presents prerequisite fundamental data protection principles for the digital solution . The principles are designed to provide guidance to the national authorities tasked with creating or overseeing the development of the digital solution. The objectives are to encourage Member States to adopt or adapt their national laws and regulations, as necessary, respect personal data protection principles, and ensure respect for the human rights and fundamental freedoms of individuals, in particular the right to privacy, in order to build trust in the implementation of the digital solution.
The data protection principles are as follows.
The personal data collected in the interest of the application of the digital solution should be processed in a fair and non-discriminatory manner, based on the consent of the data subject, the necessity to protect the vital interests of the data subject or of another data subject, or explicitly justified by legitimate public health objectives. The processing of personal data in the interest of the application of the digital solution should have a lawful basis; it should comply with applicable laws, including broader human rights standards and data privacy and data protection laws, as well as respecting the highest standards of confidentiality, and moral and ethical conduct. Personal data collected for the application of the digital solution should only be accessed, analysed or otherwise used while respecting the legitimate interests of the data subjects concerned. Specifically, to ensure that data use is fair, data should not be used in a way that violates human rights or in any other ways that are likely to cause unjustified or adverse effects on any individual(s) or group(s) of individuals. Any retention of personal data processed in the interest of the application of the digital solution should have a legitimate and fair basis. Before any data are retained, the potential risks, harms and benefits should be considered. Personal data should be permanently deleted after the time needed to fulfil their purpose, unless their extended retention is justified for specified purposes.
The processing of personal data in the interest of the application of the digital solution should be carried out to be transparent to the data subjects. Data subjects should be provided with easily accessible, concise, comprehensible and reader-friendly information in clear and unambiguous language regarding: the purpose of the data processing; the type of data processed; how data will be retained, stored and shared, or made otherwise accessible; who will be the recipients of the data and how long the data will be retained. Information should also be provided to data subjects on applicable data retention schedules, and on how to exercise their data subject rights. A list of entities authorized to process personal data in the interest of the application of the digital solution should be made public.
As the personal data collected in the interest of the digital solution may only be used for the scope and purpose identified, and they should not be processed in ways that are incompatible with identified purposes. The use of data for any other purpose, including the sale and use of personal data for commercial purposes, should be prohibited, except with the explicit, unambiguous and freely given prior consent of the data subject. The purposes for which personal data are processed in the interest of the application of the digital solution should be specified no later than at the time of data collection. The subsequent use of the personal data should be limited to the fulfillment of those specified purposes. When a health worker or verifier of the digital solution is carrying out their mandated activities ; transferring personal data processed in the interest of the application of the digital solution to a third party or allowing access by a third party should only be permitted if the principles underlying the lawful basis, as referred to above, are met; and the third party affords appropriate protection that is equal to or higher than those protections provided by the data controller, for the personal data. Personal data processed in the interest of the application of the digital solution should be relevant to the purposes for which they are to be used and, to the extent necessary for those purposes, be accurate, complete, and kept up to date.
The processing of personal data should be relevant (have a rational link to specified purposes), adequate (sufficient to properly fulfil the specified purposes) and limited to what is required to fulfil the specified purposes. The processing of personal data should not be excessive for the purposes for which those personal data are collected. Data collected and retained on the digital solution should be as limited as possible, respecting proportionality and necessity. Data access, analysis or other use should be kept to the minimum necessary to fulfil their purpose. The amount of data, including their granularity, should be limited to the minimum necessary. Selective disclosure mechanisms should be used to support proportionate data access. Data use should be monitored to ensure that it does not exceed the legitimate use. Personal data retained in the interest of the application of the digital solution should only be retained and stored for the time that is necessary for specified purposes. Personal data accessed at the point of verification of the digital solution should not be retained and stored in a repository, database or otherwise.
Personal data processed in the interest of the application of the digital solution should be kept confidential and not disclosed to unauthorized parties; personal data should only be accessible to the data subject or to other explicitly authorized parties. With regard to the nature and sensitivity of the personal data processed in the interest of the application of the digital solution, appropriate organizational, physical and technical security measures should be implemented for both electronic and paper-based data in order to protect the security and integrity of personal data. This protection includes measures to protect against personal-data breach, and measures to ensure the continued availability of that personal data for the purposes for which it is processed; this applies regardless of whether the data are stored on devices, applications, servers or networks, or if they are sent through services involved in collection, transmission, processing, retention or storage. Taking into account the available technology and cost of implementation, robust technical and organizational safeguards and procedures (e.g. efficient monitoring of data access, data breach notification procedures) should be implemented to ensure proper data management throughout the data life-cycle. Such measures are to prevent any accidental loss, destruction, damage, unauthorized use, falsification, tampering, fraud, forgery, unauthorized disclosure or breach of personal data. In case of a security breach leading to the accidental or unlawful destruction, loss, alteration, unauthorized disclosure of or access to personal data transmitted, stored or otherwise processed, users of the digital solution,n that hold health records (Data Holders) should be notified in an appropriate and timely manner. Data Holders should be notified of: any data breach; the nature of the data breach, which may affect their rights as data subjects; and recommendations to mitigate potential adverse effects.
Data Holders, if they have provided sufficient evidence of being the Data Holder, should be able to exercise data subject rights. These data subject rights include the right of access, correction, deletion, objection and restriction of personal data, subject to conditions regulated by national law, decree, regulation or other official act or order. Data subjects have the right to seek redress by a complaint procedure if they suffer harm or loss as a result of misused data or incorrect or incomplete data. Data subjects should be provided with easily accessible, concise, comprehensible and reader-friendly information about how they might exercise their data subject rights and how to seek legal redress, including how they can exercise any rights in the case of alleged fraud.
An independent public authority should be responsible for monitoring whether any data controller and data processor involved in the processing of personal data in the interest of the digital solution adhere to the principles, and may recommend revoking the authorization to collect or otherwise process data. Such a public authority should have access to all information necessary to fulfil its task. Adequate policies and mechanisms should be in place to ensure adherence to these principles.
Due to the ethical considerations and data protection principles outlined above, the following design criteria were considered when formulating the requirements for implementing a digital solution.
Digital technology should not be the only mechanism available for verification. There should always be possible ways to revert to a paper-only manual verification of records. It is important to note that despite the technological design criteria outlined here, it will be essential for Member States to ensure that the legal and policy frameworks are in place to support responsible use of the digital solution as defined by the Member State.
