Abstract

Background

A critical factor shaping parental attitudes to vaccination is the parent’s interactions with health professionals. An effective interaction can address the concerns of vaccine supportive parents and motivate a hesitant parent towards vaccine acceptance. Poor communication can contribute to rejection of vaccinations or dissatisfaction with care. We sought to provide a framework for health professionals when communicating with parents about vaccination.

Methods

Literature review to identify a spectrum of parent attitudes or ‘positions’ on childhood vaccination with estimates of the proportion of each group based on population studies. Development of a framework related to each parental position with determination of key indicators, goals and strategies based on communication science, motivational interviewing and valid consent principles.

Results

Five distinct parental groups were identified: the ‘unquestioning acceptor’ (30–40%), the ‘cautious acceptor’ (25–35%); the ‘hesitant’ (20–30%); the ‘late or selective vaccinator’ (2–27%); and the ‘refuser’ of all vaccines (<2%). The goals of the encounter with each group will vary, depending on the parents’ readiness to vaccinate. In all encounters, health professionals should build rapport, accept questions and concerns, and facilitate valid consent. For the hesitant, late or selective vaccinators, or refusers, strategies should include use of a guiding style and eliciting the parent’s own motivations to vaccinate while, avoiding excessive persuasion and adversarial debates. It may be necessary to book another appointment or offer attendance at a specialised adverse events clinic. Good information resources should also be used.

Conclusions

Health professionals have a central role in maintaining public trust in vaccination, including addressing parents’ concerns. These recommendations are tailored to specific parental positions on vaccination and provide a structured approach to assist professionals. They advocate respectful interactions that aim to guide parents towards quality decisions.

Background

The benefits of childhood vaccination are well established [1]. Vaccine uptake rates in most industrialised countries are generally high. However, two broad parental factors are associated with under-vaccination. The first relates to socioeconomic disadvantage where, despite some motivation to have their children vaccinated, parents or carers (hereafter referred to as ‘parents’) lack access to adequate resources and support to overcome logistical barriers such as a lack of transport or childcare [2,3]. The second factor, and the focus of this paper, relates to parents’ concerns about the safety or necessity of vaccines [4,5].

A critical factor shaping parental attitudes to vaccination is the parents’ interactions with health professionals. An effective interaction can address the concerns of vaccine supportive parents and motivate a hesitant parent towards vaccine acceptance [5,6]. Conversely, poor communication can contribute to rejection of vaccinations or dissatisfaction with care [7-9]. Such poor communication often results from a belief by the health professional that vaccine refusal arises from ignorance which can simply be addressed by persuading or providing more information. Such an approach is counter-productive because it fails to account for the complexity of reasons underpinning vaccine refusal and may even result in a backfire effect [10]. Parental vaccination decisions are based on an array of factors and parents integrate information according to their experiential and social contexts [11,12]. A parent’s trust in the source of information may be more important than what is in the information [13,14].

Health professionals have a central role in maintaining public trust in vaccination; this includes addressing parents’ vaccine concerns [15]. These concerns will likely increase as vaccination schedules inevitably become more complex, and parents have increased access to varied information through the internet and social media [16]. In recognition of the need to support health professionals in this challenging communication task conducted in usually short consultations, recommendations have been proposed [17-21]. Previously, most of these have focused on what is said, that is, the information that should be given to parents. Few have addressed how health professionals should engage with parents [17-21]. Since it is clear that parents want an improved dialogue about vaccinations [22-24], it is essential to focus on communication processes that build rapport and trust between the health professional and the parent [25-27].

We propose here a framework to guide health professionals in communicating with parents about vaccination. By focusing on both what is said and how it is said, we attempt to provide an integrated, generic approach going beyond simply the one-way provision of information.

The framework is informed by evidence from decision making and communication research and is applicable for use by all health professionals in their vaccination discussions, particularly where there might be parental reluctance to vaccinate. It focuses on recommended childhood vaccines but is also applicable to discussions with other groups recommended for vaccination. We propose categories or ‘positions’ that reflect different parental attitudes and behaviours regarding vaccination and suggest specific communication strategies tailored to each position. The overarching goal of the encounter is to promote quality decisions and, ultimately, vaccination.

Development of the framework

The framework was developed to:

a) be acceptable to health professionals

b) increase health professional and parent satisfaction with discussions about vaccination

c) increase a health professional’s self-efficacy (sense of confidence and competence) in relation to communicating about vaccination

d) increase the likelihood of the parent making a decision based on evidence (by increasing access to quality information)

e) encourage uptake of recommended vaccines.

There were four stages in developing the framework: a literature review, classifying parental positions on vaccination, matching strategies to these positions and assessing their face validity with heath professionals.

Stage 1: Literature review

This aimed to (1) identify existing research that had classified parents’ positions based on their attitudes and behaviours regarding childhood vaccination and (2) identify articles that contained strategies to communicate with parents about vaccination. We searched MEDLINE (1996–), PsycINFO (1967–), CINAHL (1982–), and EMBASE (1980–) in September 2010. The following combination of keywords and associated MESH headings (identified for each database) was used: child$ or infant$ or newborn$ or baby or babies AND vaccin$ or immunis$ or immuniz AND decision$ or choice behavio$ or choic$ or communicat$ or consult$.

The searches identified 3168 total hits (including duplicates) which was reduced to 112 after screening titles and removing duplicates. Of these, we identified three studies that proposed a spectrum spanning the parental positions on vaccination. These are described in Table 1[28-30]. We found nine papers advising health professionals on communicating with patients about vaccination but none that tailored communication to empirically derived parental positions [17-21,31-34].

Table 1. Summary of studies identifying parental positions on vaccination

Stage 2: Identifying parental positions on vaccination

We reviewed the classifications presented within the three identified studies, [28-30] summarised parental positions from each study, and discussed their relevance to vaccine communication. A discrete number of parental positions relating to vaccination attitudes and behaviour were proposed, discussed and revised based on the categories’ applicability to clinical interactions and international relevance. The final set of five parental positions are described in Table 2. A range for the approximate proportion of each group is given based on population surveys or registers from the USA, European Union, New Zealand, and Australia [4,28,35-44].

Table 2. Parental positions on vaccination according to attitudes and behaviours

Stage 3: Matching strategies to parental positions

For each parental position, we proposed an overall communication approach then more specific guidance tailored to each parental position (1 3 and 4). Given that no tailored guidance was identified in the literature review, the specific strategies were informed by the literature on health communication; [48,49] our professional and educational experience; valid consent principles, [50] and those of motivational interviewing which uses a guiding style to promote healthy behaviours [51].

Stage 4: Seeking feedback from health professionals

To assess general acceptability of the framework and recommendations, accredited nurse immunisation providers were presented with them in three annual update sessions, and 104 completed a short questionnaire about usefulness (scored from 1 ‘not at all useful’ to 10 ‘extremely useful’), realism (not at all/somewhat/very), strengths (open question), and areas for improvement (open question). Feedback was positive with a median score for usefulness of 8.8 (range 3–10); 74% rated the framework as ‘very realistic’, 26% as ‘somewhat realistic’, while no-one rated it as ‘not at all realistic’. General practice immunisation coordinators, immunisation experts, and a consumer representative (n = 20) all provided verbal feedback on the draft framework. All feedback was used to inform revisions of the recommendations.

The framework

How discussions are addressed

While the majority of parents accept vaccination (Table 2), attendance at the consultation should not be presumed to indicate consent. Ideally parents will receive credible information prior to their child’s appointment. Health professionals have a responsibility to ensure that parental consent for vaccination is valid. This requires more than simply giving information and is built upon a relationship and interaction [50,52].

Building trust is paramount in any healthcare interaction. As noted by Benin et al, the trusted health professional is one who: has spent time with the child and parent; listened to, accepted and addressed their concerns; possesses the necessary scientific information; and uses a whole-person approach that is not patronising but treats parents and their children as individuals [29]. Table 3 lists unhelpful and helpful approaches to communication with all parents.

Table 3. Unhelpful and helpful strategies for addressing parental concerns about vaccination

Health professionals’ body language ideally indicates that the discussions are important and distractions, such as using computers while talking, are best avoided. They need to speedily establish rapport and clarify parental concerns, avoiding the temptation to minimise or dismiss these (“Oh there’s nothing to worry about, vaccination is very safe nowadays”) [27,53]. Instead it is important to fully understand parents’ concerns and motivations using open questions and empathic responses [27]. Although health professionals may be reluctant to encourage questions [27,54], with practice, targeted questions allow health professionals to tailor their discussions [51].

Giving information is an integral part of the immunisation encounter. Here, the skills for efficient information provision are useful - primarily ‘signposting’ and ‘chunking and checking’ (see 1 5, 6 and 7 for examples) [49]. Signposting is the skill of clearly indicating to the parent (or patient) the different phases of the consultation. Chunking and checking refers to the provision of information in small chunks followed by checking the person’s understanding. This technique contrasts with the common practice of providing much larger amounts of information before checking, which can lead to information overload.

What to include in discussions with parents

It is important to communicate risk effectively [56]. It is recommended that health professionals give information about common but minor side effects, and rare but serious ones [57]. Written materials, web links, or decision aids given prior to, or used during, the consultation can be helpful [58-60]. In a recent UK survey 156 primary health care professionals viewed the inclusion of a web link for an online MMR decision aid contained in a parents’ MMR pre-vaccination invitation letter as an appropriate way to support parents coming to the consultation [61]. Written resources may be available in electronic/online or paper format. These vary widely between countries and clinicians should be familiar with how to locate them.

Risk communication is best tailored to individuals. In general terms outcomes are better understood when they are specified and when their probability is given in numbers (e.g. 1 in 1000) although some may prefer words [62]. When presenting probabilities, there remains conflicting evidence over whether natural frequencies (e.g., 1 in 100) or percentages are preferable [63]. A recent study concluded that percentages may be better understood than natural frequencies [64]. To avoid confusion, a consistent denominator should be used when presenting event rates for comparison [65]. Visual representations of probability have also been recommended and are commonly used in decision aids [59,61].

Specific information is most helpful when it is timely, consistent, relevant, up to date, and, where available, local. Parents should also be advised about how to manage the common side effects of vaccinations and how to seek help if they have further concerns [66].

A tailored approach

Evidence from other areas of healthcare practice suggests adapting the principles of motivational interviewing. This is a form of communication that uses a guiding style, rather than a directing style, for discussions where there is ambivalence and resistance to change [51]. Motivational interviewing involves asking questions that clarify an individual’s responsiveness to change and elicits their own motivations for change. The method has demonstrated effectiveness in a range of health behaviours [67]. In this particular context, the ambivalence and resistance to change relates to whether or not a parent should have their child vaccinated rather than focusing on a behaviour such as quitting smoking.

It should also be borne in mind that motivational interviewing builds upon the Transtheoretical Model [68]. This is a framework for understanding the process of behaviour change where individuals may pass through five stages: precontemplation, where they are not considering change; contemplation, where they seriously consider change; preparation, where they plan and commit to change; action, where they make a specific behavioural change which if successful, leads to maintenance of that behaviour, the fifth stage.

Accordingly, Table 4 strategies tailored to the parent’s stage. The majority of parents are in the action and maintenance stage (cautious or unquestioning acceptors). Some will be contemplating or even preparing to immunise – what we describe as ‘hesitant’ parents. Late or selective vaccinators, who are willing to have some vaccines, may also contemplate full vaccination if guided by a health professional [5]. ‘Vaccine refusers’ are usually in the pre-contemplation stage where they are not considering vaccinating at all. It is unrealistic to expect such parents to move to the action stage at one visit. However, the goal may be to guide them toward contemplating vaccination. This would be done by asking permission to discuss; encouraging them to explore the pros and cons of their decision; and eliciting their own possible motivations to change (Table 4).

Tables 5, 6 and 7 give examples of suggested dialogue for unquestioning and cautious acceptors, hesitant, and refusing parents. For late or selective vaccinators, strategies can apply from those suggested for hesitant and refusing parents. A parent’s starting position can be clarified with initial questions (How do you feel about the vaccinations?) and observation of their body language.

It may also be possible to flag specific questions or concerns for discussion prior to the consultation. For example, a question prompt sheet for parents to use in consultations about MMR vaccination was positively evaluated by 46 parents in a UK study [69]. Specifically parents reported that the prompt sheet enabled them to feel confident in ‘raising the issue of MMR’ with their GP or nurse.

The goals for the consultation will vary according to the parent’s position. Health professionals should avoid a mismatch between the parent’s expectations and needs and their own assumptions. For example, a ‘hesitant’ father may be planning only to obtain information but feels he is being pressured to vaccinate. The cost may be loss of his trust and a subsequent unwillingness to return. Similarly, a ‘refusing’ mother might be approached by a health professional who is intent on changing her mind [70]. This ‘righting reflex’ is the natural response of health professionals to instinctively ‘put right’ healthcare problems rather than finding out patients’ concerns or points of view. It may lead to an adversarial position and further entrench the parent’s views, closing the door to any future possible gains [71]. In this situation, a better goal would be to build a rapport that may lead to willingness for further discussion or partial vaccination. Vaccine-refusing parents may be willing to consider an alternative schedule and may be willing to hear how to recognise and respond early to signs that their child may have a vaccine-preventable disease (Table 4).

Table 7. Example of dialogue with the vaccine-refusing parent

Discussion

As vaccine preventable diseases become less common, parents in industrialised countries appear to be expressing more concerns about the safety and necessity of vaccines. This could lead to a decline in vaccination uptake rates to a level which allows the diseases to re-emerge and become significant health problems [73].

Health professionals have to juggle the need to consider the population at risk of the disease (particularly if vaccination rates drop) alongside addressing the needs of the particular parent who is raising concerns about what to do for their particular child. These concerns centre on an increasing number of vaccines given to children, their safety, composition and necessity.

Since interactions with health professionals provide a focal point for parents’ concerns to be expressed, it is important that communication during these interactions is effective [26]. The parental positions described in this paper act as a starting point for health professionals to choose the most appropriate communication strategy. Naturally these will vary according to the parent’s individual needs and circumstances.

The literature review informing the parental positions found only three papers providing a spectrum of attitudes to vaccination. While there is a vast literature exploring attitudes to vaccination among parents [3,7,74,75], we sought to identify only studies that would provide a spectrum of attitudinal positions that would theoretically account for all parents.

However, the spectrum described does simplify what is often a complex process of decision making which may involve parents moving between positions over time. Indeed, as noted in the wider literature, parents’ decisions are also made in a broader context of beliefs about a child’s health, personal experiences, perceived norms, and trust in health systems and professionals [12,29,76]. While the parental positions were developed from three US studies, we have applied our knowledge and experience from other countries to their modification.

The approximate proportions of each parental group are estimates from population-based surveys and will vary over time, within regions, and between practices. For example, the estimate for the percentage of parents completely refusing all vaccines is given as less than 2% based on population data but there are clusters of much higher refuser rates in specific localities [43,44,77]. Nevertheless, giving ranges for the sizes of the groups may assist health professionals and programme coordinators in planning for targeted information and strategies.

We have proposed an approach to communication that encourages questions and employs a guiding rather than directing style. The reality of busy clinical environments can act as a disincentive for health professionals to actively seek out questions and concerns [54]. However, the framework we propose may ensure that consultations are more time efficient because it provides a structure to more rapidly identify the parent’s position on vaccination, the most appropriate goals for that consultation, and the parent’s specific information needs. Practised interviewing techniques enable the health professional to quickly focus the discussion on the specific concerns of the parent. In interactions with vaccine-refusing parents, some health professionals attempt to change the parent’s mind [70]. As this goal is usually unrealistic, the consultation can become long and difficult and result in an impasse. Having more realistic goals will facilitate a more satisfying and time efficient discussion which may then be followed-up as needed.

Communication strategies to date have lacked clear evidence of efficacy in vaccination settings. We have described a framework for talking with parents about vaccination. It is informed by evidence and acceptable to the health professionals involved in the formative evaluation sessions, but now needs to be more fully evaluated. This may involve group or individual training of health professionals who undergo assessment using standardised patients and validated scales that measure quality of communication [78]. To measure effectiveness of the framework against the aims described above (satisfaction, self-efficacy, decision quality and vaccination uptake), a randomised controlled trial delivered at cluster (e.g., GP practice) or individual level would then establish its effectiveness compared with ‘usual care’.

Conclusion

Good communication is part of a suite of measures needed to maintain high uptake of child vaccines. Strategies must also continue to address barriers such as access to healthcare and provider factors [79-81]. Nevertheless, there is an urgent need to build an evidence base which informs vaccine communication, given that the parent–provider interaction remains integral to maintaining public confidence in vaccination.
