What can we do to reduce vaccine hesitancy?

The SAGE Working Group on Vaccine Hesitancy defined vaccine hesitancy as ‘the delay in acceptance or refusal of vaccination despite availability of vaccination services. Vaccine hesitancy is complex and context specific, varying across time, place and vaccines. It is influenced by factors such as complacency, convenience and confidence’ (1).  Indeed, it is complex and the reasons cited in the literature are varied, from fears about vaccine safety, worries about ‘overloading’ the child’s immune system, distrust of the pharmaceutical industry and collective amnesia regarding the dangers of vaccine preventable diseases (2). Many parents, unfamiliar with diseases like tetanus and meningitis, make incorrect conclusions when it comes to calculating the risk-benefit of vaccinating their children.

The current measles outbreak in Europe is the direct result of vaccine hesitancy. 13,234 cases have been reported across Europe since July 2017 (3). Sadly, there were also 18 deaths due to measles in this period (3). In Ireland, we have had 76 cases of measles in 2018 so far, with an ongoing outbreak in Dublin as I write this. What can we do to end this outbreak and prevent the resurgence of other vaccine preventable diseases?

Reviewing the current evidence on what can be done to address vaccine hesitancy is not particularly inspiring. Reminders, whether they are telephone, text or postal, and family incentive rewards have been proven to increase vaccine uptake, but there is limited evidence that they work for vaccine-hesitant individuals (4). A trusted health care professional can also have an impact on changing parental attitudes, but the evidence for the various communication tools that have been designed as aids for these professionals to use is mixed (4). More research and better measurement of outcomes is needed in this area (4). It is not enough just to measure change in attitude to vaccines, we must see if this change in attitude actually leads to increased vaccine uptake.

Example of the spread of an outbreak in the game Vax!

There are advocates for more innovative approaches. Some argue that social marketing frameworks could provide solutions (5). Others propose that children should be taught positive messages about vaccinations in school, as part of their health education, science or even citizenship classes, in order to ‘inoculate’ them against vaccine hesitancy in the future (6). A friend of mine, who teaches teenagers, created a lesson to teach her students critical analysis skills, using information on the benefit and safety of HPV vaccination. These kind of skills are vital for navigating the ‘fake news’ widespread on social media. For younger children, there are online games demonstrating how vaccines work (7). One review found 16 different games in 2016 (7). I lost 20 minutes trying to stop an outbreak with rapid vaccination at this particular link: https://vax.herokuapp.com/game  

It’s a little bit addictive! Could positive attitudes to vaccines be engrained at a young age using these methods?

A mixture of targeted interventions to deal with parents in the midst of today’s crisis, as well as methods targeting future generations, will be necessary to tackle this complex issue. It is time to try new approaches. Please contact me at laura.heavey@hse.ie, if you know of any innovative methods to improve vaccination rates that are ongoing in your country

A crossroads for Public Health in Ireland: Slaintecare and proportionate universalism

This July the UK celebrated 70 years of the National Health Service which famously entitled healthcare to all “from cradle to grave”. Unfortunately progress on universal healthcare in the post-colonial Irish state has been much slower. In May 2017, a cross-party parliamentary committee produced a 10-year plan for the future of healthcare. Their report was called the “Sláintecare Report” (Sláinte translated from Irish means health) (1). It was ambitious with many recommendations including:

  1. The phasing out of private care in public hospitals
  2. Eliminate charges for access to public hospital care
  3. Reduce drug prescription charges
  4. Universal access to GP care without charge
  5. Expand public hospital capacity
  6. Reduce waiting lists for first outpatient department appointments and hospital treatment

However, progress on implementation has been slow and the signs are that the required funding will not be made available in the next budget. This is not the only barrier to implementation, doctors’ unions including the Irish Medical Organisation have come out against the plan to remove private medical practice from public hospitals (2).

This points to an important aspect within an Irish healthcare system which is the role of private healthcare. Figure 1 shows that amongst Euronet countries for which data is available from the OECD, Ireland has the highest per capita spend on healthcare and the highest spend on voluntary private health care and out of pocket payments (3).

Figure 1. OECD data on per capita spending on health (all functions) of Euronet countries in 2016, based on current prices and current purchasing power parity in US dollars

The Whitehall Studies, led by Sir Michael Marmot, was a prospective cohort study of civil servants in the UK between 1967 and 1988 which examined the relationship between mortality and employment status. They demonstrated that even when controlled for lifestyle factors such as, smoking status, blood pressure, obesity and cholesterol, mortality rates followed a gradient from those of lowest status to those of highest status. For instance, those men in the lowest grade had a mortality rate three times that of the highest grade (4).

This result showing a social gradient in health outcomes has been replicated many times and the idea of “Proportionate Universalism” was coined by Sir Michael Marmot and proposed as a means of addressing this gradient of health inequalities in the “Marmot Review” (5). It describes public health interventions which are aimed at the entire population, universal, but which are proportionally weighted in favour of those in most need.

Proportionate Universalism has shown success in reducing health inequalities in the UK by addressing inequalities in healthcare provision and in the social determinants of health (6). However, it is not clear this means of addressing health inequalities would be sufficient to make a meaningful difference in an Irish context.

The continuum of health need in Ireland is not linear, with a major influence on this based on the marketization of healthcare within the system. Those who can afford Private Health Insurance have better access to hospital consultants and diagnostics, even within the public system (7). On top of this there are further financial barriers in out-of-pocket payments for primary care and prescriptions. Like Julian Tudor Hart described in his paper on the “Inverse Care Law”, those with most need have the least access to services (8).

The two tiered nature of the Irish healthcare system was encapsulated in the name of a book written 10 years ago on the subject called “Irish Apartheid”. If a Proportionate Universalism public health strategy is to be effective in Ireland we must follow the example of our European neighbours and move towards universal healthcare, oppose doctors who wish to protect their private practice and give our support to the spirit of Sláintecare.

Service sanitaire: a first step towards the decompartmentalisation of the French health system?

In September 2018, more than 45 thousand French health students will be involved in the “sanitary service” (service sanitaire). This program has been launched by the French government in January 2018 and it concerns medical, dental, nursing, physiotherapy, and midwifery students; all other health students will be involved from 2019 on. The objective is to train them in prevention and health education, competencies that are now missing from most health training curricula, through the elaboration an implementation of a practical project to the benefit of the population.

The sanitary service responds to the first axe of the national health strategy 2018-2022, which is to develop a prevention and health promotion policy. Throughout three weeks, the students will be trained in public health, project management, prevention, health promotion and they will then have three weeks of hands-on experience in a interdisciplinary team. They will be supported by a pedagogic referent (référent pédagogique) from their university and a proximity referent (référent de proximité) from the structure where they will intervene. The places of intervention will mostly be middle and high schools, but also retirement houses and structures managed by social services.

The biggest challenge for universities, at one month from the beginning of the program, is to provide a quality training and support to the students, in order to respond to the expectations and needs of the structures where they will intervene, the population and the students themselves.

EuroNet MRPH Working Group on e-cigarettes and tobacco harm reduction: A research to assess competencies amongst Residents in Public Health

The fight against smoking is an international problem and, in many cases, it is far from being adequately implemented. An essential starting point to perform a comprehensive and accurate medical program for smoking cessation is the healthcare professionals’ awareness about smoking products and smokers’ habits. In fact, in the last years, customers have changed their behaviours and tastes, switching from consumption of normal cigarettes to electronic cigarettes (e-cigarettes) or other nicotine and tobacco products.1

Available literature shows that the actual healthcare professionals’ level of knowledge on this issue is sub-optimal, with likely negative implications on chances to help users to undertake cessation or harm-reduction pathways.2

Public Health workforce – current and future – has a major role to play here, as on the identification of better prevention policies and strategies. Hence, the idea underpinning this Working Group with EuroNet MRPH. This research comes from a proposal joint with Prof. Josep Maria Ramon Torrell of the University of Barcelona, Spain (Hospital Universitari de Bellvitge): with him, we designed the study protocol, with the aims to evaluate, through a European cross-sectional survey, the current level of knowledge about e-cigarettes and tobacco harm reduction strategy, and to highlight possible weaknesses in public health residency curricula in order to enhance Public Health Residents’ competences on these topics.

Multinational survey assessing learning climate and satisfaction during Public Health residency: an update from the Working Group

Learning climate has an important impact on knowledge and skills we acquire during residency. It encompasses many important aspects, such as the quality of supervision, professional relations between colleagues, quality of formal education and others. Numerous studies in the literature have sought to assess quality of training in different areas of medicine. However, in the area of public health training, there are no published studies on learning climate assessment or residents’ satisfaction during the residency.

The lack of literature in the area of assessing Public Health training inspired us to start a working group, which will perform a multinational study assessing learning climate and satisfaction during Public Health residency. The purpose of the study is to prepare the basis for evidence-based improvement of public health training in Europe.

Literature review was performed to identify tools currently used to evaluate learning climate during medical residency. Of all the questionnaires available, the working group chose D-RECT as the most applicable for our study. With author’s permission, we modified the questionnaire to suit Public Health residency. The new adapted questionnaire consists of 50 questions divided into 12 subscales. We proposed a new name for the modified questionnaire: European Residency Educational Climate Test (E-RECT).

The study will start after receiving the Ethics Committee approval. At this stage of the study, the questionnaire is being translated via a back-and-forth process into the language of each country. The piloting and validation process will follow, before we distribute the questionnaire  to all public health residents in each country.

The data obtained in the study will provide the opportunity to compare results between different countries and see what are the differences, the good practices and the opportunities to improve national residency programs. We encourage residents to respond to the invitation, when they receive it – fill in the online questionnaire to ensure that your voice is heard.

Summer Reading: “Deadly Outbreaks”!

Summer time, hot weather, (almost) everyone on vacations… Well, not me! But during the weekends I choose to hang out at the terraces of nice cafes, enjoying the good weather with some friends. I could tell you I usually drink water and natural juices in these occasions but I would be lying: a glass of red wine or some nice sangria are my options on these relaxed afternoons.  It is the perfect timing to read a nice book, too. The last one I read was “Deadly Outbreaks” by Alexandra Levitt(1) and was result of a purchase on the internet, while searching for books on public health issues.

Before going to medical school, I was already working in infection control area at a 400 bed hospital, where epidemiological surveillance is an important component of our functions and, I must admit, one of my favorites. During these 13 years of work at this hospital, I already had to deal with few outbreaks but it was the one in the summer of 2006 I remember the most, when I was still a “freshman” in the Infection Control Committee. At the time, the microbiology laboratory gave us an alert: multidrug-resistant (MDR) Acinetobacter baumannii was isolated in sputum of a trauma patient transferred from a central hospital some days before.  After a first assessment we found out he was located in the Surgical Intermediate Care Unit, a small pos-op infirmary “packed” with 6 patients, where the distance between beds was roughly 1,5 meters and in which “our” patient was frequently coughing and in need of nursing care. This microorganism was not part of our local ecology, so this was considered an infection control “code blue”! The patient and the unit were immediately put in contact isolation, while the lab confirmed other two positive patients for MDR A. baumannii. An outbreak was officially declared and, with the support of the hospital management, rigorous infection control measures were taken: all contacts with this patient were identified and put in contact isolation, an epidemiological line list was done and an active surveillance protocol was implemented. The unit was closed to new admissions, environment hygiene measures were reinforced, patients were stratified by risk level and a cohort of healthcare workers (HCW) was put in place (specific teams of HCW took care of “confirmed”, “suspected” and “negative” patients). Meanwhile, the hospital that transferred the index patient warned us that they were experiencing problems with this microorganism but this information came to us too late… After eight months, 15 cases (8 of which died), 61 patients put in isolation and surveillance, and a lot of effort (and costs) for the hospital, HCW’s and patients, the outbreak was finally controlled. As a consequence of it, a surveillance protocol for MDR A. baumannii was implemented (applied for all patients transferred from other hospitals). In my opinion, one of the “lessons to be learned” from this outbreak is the importance of communication between and within healthcare units to be able to minimize infection control risks, related to patients mobility. Twelve years have passed and, today, this and other hospitals have a risk evaluation procedure that is applied to all admitted patients.

But back to the book: if you liked this outbreak description, you will LOVE “Deadly Outbreaks”1 and you won’t be able to sleep until you end it! The author, Prof. Alexandra Levitt, is an expert on emerging diseases and other public health threats and worked for the Center for Disease Control and Prevention (CDC). She dedicates this book to all field epidemiologists that “save lives threatened by killer pandemics, exotic viruses and drug-resistant parasites”. The book describes, in an exciting and pedagogical way, seven public health mysteries occurred in the United States of America between 1976 and 2006, through the learn-by-doing approach of the “medical detectives” of CDC´s Epidemic Intelligence Service. In the “author’s note”, three advices are given, namely: “be prepared for the unexpected” (when it comes to infectious microorganisms); “we are all in it together” (with the phenomena of globalization, wherever we live, we are all at risk) and the importance of participating in a strong public health system, in the pursuit of prevention of disease spread among the community.

In one outbreak described in the book, investigating the mysterious death of several infants at a Children´s Hospital, several epidemiological tools were used, including the “epi-curve” and the “relative risk of death” associated with each nurses’ shifts, estimating the risk of a baby dying when a specific person was on duty. The study concluded that the hospital should strengthen central control of medicines and implement a monitoring system of deaths, by time and place, within the hospital. (2)

Did you know that, as a consequence of an outbreak in a Philadelphia hotel affecting middle-aged Legionnaires, CDC fielded one of the biggest investigative team ever but couldn´t find its etiological agent for several months? In fact, it was a young microbiologist of CDC that discovered it when, later on, decided to review and explore the finding of some rods that he, first, assumed were contaminants of his cultures (“be prepared for the unexpected”, remember?). Did you know that, after its discovery in 1976, Legionella pneumophila was retrospectively implicated in cases as far as 1943?

More recently, did you know that an epidemiologic outbreak investigation, affecting abattoir workers exposed to porcine brain, led to the discovery of an immune-mediated polyradiculoneuropathy? (3)

Throughout the book, these and many other epidemiological and infectious diseases facts are given, engaging the reader to explore the scientific method, by testing various hypotheses through the use of the technologies available at the time of the outbreak. At the end of each chapter, the author reviews the main facts to illustrate the lessons learned. Did I catch your attention? Hope so! Despite the book portraying the modus operandi (and available associated resources) of the North-American reality, it’s full of interesting facts that, in my opinion, will enrich our knowledge in public health area. A “must-read”!

What do you think #PublicHealthLooksLike? An unusual (but rewarding) PH resident attachment

In my experience it’s not very often that you get to combine your public health work with your hobbies, particularly when your outside interests include the arts as mine do. However, in my current role I am for the first time being able to do both daily, which has been exciting, rewarding and challenging!

For the last two months I have been working with the UK Faculty of Public Health (FPH) communications and policy team. They cover a lot of ground and I’m involved in several workstreams, but the main piece of work that I ‘own’ is the planning, implementation and promotion of their photography competition #PublicHealthLooksLike.

As the name suggests, the competition is aiming to improve the way FPH represent their members (i.e. the public health workforce) by showcasing what public health work really looks like in the UK and around the world, rather than using stereotypical ‘stock photo’ images of attractive models with stethoscopes. They’re offering some great prizes including £250 and a year’s free membership, but most importantly they’re planning an exhibition in London featuring the top ten photographs to celebrate the amazing diversity of public health.

Although the competition has only been running for six weeks and doesn’t close till October 19th, it’s already been incredibly inspiring to see both the engagement from public health professionals and the early entries coming in. I suppose we all know in the abstract that public health is a broad church, with people working in so many different areas, but there’s a big difference between knowing that and actually seeing it visually. We’ve had photos of anything and everything, from people supervising walking groups in the sunny English countryside to members hosting immunisation clinics in the Middle East.

From a personal point of view, I’ve loved being able to engage with potential entrants online, encouraging them to recognise their talents and the incredible work that they do every day without probably realising how interesting and engaging that might be to other people. It’s made me think seriously about how little I talk about or share my own public health work, and try to (slowly) increase the amount of personal and professional engagement I do on Twitter and other social networks. We should all talk more about what we do, because it’s often only by hearing and seeing the experiences of others that we become inspired to seek out new challenges – that’s partly why networks such as Euronet are so important.

The competition is still running, and I would definitely recommend Euronet members enter to showcase the work that we all do on a daily basis across Europe! You can enter up to five photos through the competition website. If you’re on Twitter it would be fantastic if you could take 10 seconds to RT this tweet to publicise the competition across Europe more widely, and if you fancy following either @FPH or me personally you can find us there as well.

I look forward to seeing your entries! If anyone is interested in hearing more about the competition or attachments with FPH, please just drop me an email at rachel.thomson8@nhs.net.

Local Health Plans: Value and Structure

Any health plan ultimate goal is to improve health and to reduce health inequities, with minimum resources, based on a value for health approach. A local health plan should follow strategic orientations from European, national and regional levels in order to achieve the sustainable development goals established by the World Health Organization. This idea of top-bottom guidelines is fundamental, although the usual short time frame may affect the evaluation of its implementation in terms of outcomes and impact.

Building Local health plans is responsibility of the public health team and health planning is its cornerstone. Also, it represents a social commitment, since it involves collaboration between stakeholders and individuals of a community in all of its phases. These interested parties are numerous actors that play a role in the community, taking direct or indirectly action in the health of the population. Their interventions should contribute to Health in All Politics (no longer policies) concept, and represent a stronger and empowered view of the results that all actions can have on community’s health and well-being. The plan should have a strategic format to provide all stakeholders with the right tools to take it into action; always in a whole-of-government and whole-of-society point of view. They should be diverse in their activities, in order to reach all citizens in different life settings. However, family, school, workplace, healthcare institutions and social environment are priority contexts and require the most adequate interventions.

Figure 1 – Health planning cycle (Adapted from Imperatori and Giraldes 1982, Metodologia do Planeamento da Saúde, Lisbon)

Local health plans are based on the stages of the health planning cycle (figure 1) and start with an analysis of the local health situation assessment, withdrawn from the local health observatory. This information allows the drawing of the first list of health problems and their determinants, which, subsequently, are prioritized. The next step involves the setting of objectives and selection of strategies in collaboration with all stakeholders, taking into account the main health problems identified. During and after the implementation of the plan, it should be monitored and evaluated, as these are important components to ensure its fulfillment, using core indicators.

The health planning cycle should never be interpreted in a two dimensional (2D) perspective. Its structure allows transforming all outputs from evaluation phase to inputs used in the next step. Therefore, from a 3D analysis, the health planning cycle is a spiral which ends in an ideal health condition (utopian perception). It may be considered an iteration cycle, a process used to make anything better over time.

Therefore, a local health plan is a fundamental tool to implement the best practices available and improve population health. Its use must be encouraged and widespread. The importance of stakeholders in all course of action is their multisectoral response and their ability to build bridges between them, centered on population health and well-being. Thus, the interested parties should cover all society sectors based on Health in All Politics approach, leading decision makers to innovate and going beyond an ordinary policy plan.

Vaccine hesitancy: how to communicate with hesitant parents: the C.A.S.E. approach

The SAGE Working Group on Vaccine Hesitancy concluded that vaccine hesitancy refers to delay in acceptance or refusal of vaccination despite availability of vaccination services. It is characterized by different factors in different contexts (political, ideological, social, etc.). Vaccine hesitancy is complex and context-specific, varying across time, place and vaccines. [1]

When approaching a hesitant parent, one must never forget that all his doubts are dictated by a strong perception of risk and by the consequent concern for the safety of his offspring. In this context, information concerning the “danger” or the factor considered as such, is connected and elaborated not only at the cortical level, but also in the limbic system which, thanks to its connections with the pre-frontal cortex, comes into play in the decision-making process, based on emotional reactions.

For this reason, any information you want to transmit to the defaulting mother or father, this must be simple, immediate and preferably proposed using the visual means (eg: simple graphs or sample images that can visually reproduce what you intend to explain), according to the rules of cognitive ergonomics. [2]

In the United States in 2010 Dr. Singer developed a communication model that, referring to Aristotelian rhetoric, provides an effective and efficient approach to communicate with the hesitant parents (C.A.S.E. approach). C.A.S.E. is an acronym that identifies the four phases of the communicative approach, Corroborate, About me, Science, Explain / advise (Fig.1). [2,3]

The first phase, Corroboration, which coincides with the Aristotelian technique of pathos, consists in proving emphatic towards parents who do not want to vaccinate their children, that is to listen, welcome and understand their doubts and their fears. Parents must perceive that who they are in front of is not an enemy whose purpose is to oppose them and impose on them a different way of thinking and acting, but it is a person who shares their primary interest, the health of the child. To achieve this, it is very important to find a point of agreement from which to start. [3,4]

In the second phase, About me, or ethos according to Aristotle’s rhetoric, the health worker should explain to parents what is his working mission (e. g. to advance the health of all people, the children’s sake) and what path he has taken to realize it (the studies, conferences or courses in which he participated, various studies). [3,4] The objective is to qualify the speaker, increasing its credibility and making it an authoritative source of information.

The logos of Aristotle is taken up again in the Science phase of Dr. Singer, in which the scientific evidence about the vaccines is presented to the parents. [3,4] It is in this phase when the cognitive ergonomics, mentioned above, comes into play strongly. To make the interview less dispersive, it is advisable for the doctor, already in the corroboration phase, to let the parents express the factors of greatest concern. This on one hand allows to partially reduce the anxiety of mothers and fathers, on the other hand allows the doctor to focus only on some aspects related to the vaccines and not on all the knowledge about the subject.

Fig. 1 Example of C.A.S.E. approach proposed by dr. Singer (2010)

Finally, to conclude the interview, the explain / advise phase should allow to sum up what has been said and give advice to the hesitant parents based on scientific evidence. [4]

The effectiveness of the C.A.S.E. method against hesitant parents has not yet been evaluated in any study. Therefore, assessing effectiveness in the field would be appropriate.

Drinking Water: A Public Health Issue

The access to safe drinking water is essential to health and a basic human right, as well as a structural part of an effective policy for health protection. (1)

Since 1958, aiming primarily to protect public health, the WHO has published several editions of a document, currently called WHO Guidelines for drinking-water quality, which has been regularly updated through rolling revision. This document establishes the principles and guidelines that are the base for the national programs of the United Nations members. (1)

The model for regulating water quality in Portugal has been progressively consolidated through regular legislation revisions that reflect scientific and technical progress. The consequences have been globally positive and are evidenced in a favourable evolution of the indicator on “safe water”, which builds on the fulfilment of sampling frequency and the observance of parametric values (e.g. microbiological and chemical). Figure 1 shows the evolution of the quality level of drinking water; nowadays 99% of water is guaranteed to be controlled and of good quality (in 1993 this indicator was at a mere 50%). (2) (3) (4)

This excellence level is supported by strictly monitoring the stakeholders in this process, among them health authorities that may be integrated in Public Health Units (PHU). (3)

The Activity Plan of the ACeS Alto Ave PHU includes a program of sanitary surveillance for drinking water systems with public distribution. These systems undergo annual characterization as a way to promote risk analysis and management for health. I have recently followed my unit’s environmental health technician on his visits to the drinking water systems in the Fafe area.

These visits started at a Water Treatment Station, where water undergoes a complex treatment process after catchment and is then sent to several reservoirs in the area, which then distribute the water to consumers. Besides verifying the maintenance, hygiene and safety parameters, the process also identifies the treatment types for water (e.g. pre-oxidation, decantation and filtration).

We have then visited all the storage reservoirs in the area where special care is given to the inner lining of tanks/cells, vent protection and latest sanitation date.

Some locations, due to their position and/or demographic rate, benefit from local water capture (e.g. water holes, water springs or wellheads). These Dispersed Systems have their own device for water purification with sodium hypochlorite and sometimes pH correction with caustic soda.

These visits allow us to promote the conservation and maintenance of several infrastructures of the public water supply systems by the appropriate authorities. But they also allow Public Health physicians (as Health Authorities) to intervene in a stricter and more appropriate way in the case of potential infringements of the chemical or microbiological parameters reported. It may therefore be necessary to establish measures to minimize health hazards to the population. (2)
