  • SBI-0206965 Vaccine recommendation behaviors were self repor

    2018-10-23

    Vaccine recommendation behaviors were self-reported, which is a limitation of our study: declaration or desirability biases cannot be excluded. However, questionnaire data appears to overestimate SBI-0206965 rates by less than 10% (Brien et al., 2012), and self-reported pandemic or seasonal influenza vaccination coverage in hospital healthcare workers has been shown to be a good proxy for recorded vaccine coverage (Llupià et al., 2012). Validating the self-reported data by retrieving reliable information about GPs\'behaviors from patients\' files was not feasible, even for a limited sample of GPs, especially as very few GPs in private practices consistently record data about patients and consultations. The Cronbach alpha of the scores for vaccine recommendations (0.74 and 0.63) and principal component analyses confirmed the internal validity of the scores. Moreover, several reasons indicate that these scores are better proxies for VH than the separate study of each vaccine situation separately. First, the notion of VH is defined by a variety of behaviors and attitudes toward different vaccine situations, not by a single, unidimensional approach of opposition (Larson et al., 2014; Dubé et al., 2013). Second, GPs\' self-reported recommendation frequency may also reflect in part the degree to which they are favorable to vaccines (Larson et al., 2014; Peretti-Watel et al., 2015). Finally, the strong association between the recommendation scores and GPs\' own vaccination behavior scores confirms the robustness of the global score as a proxy for VH. Two final weaknesses must be noted. Because this vaccination survey is cross-sectional and retrospective, no causal inferences can be drawn. In addition, because VH depends highly on context, it is possible that our results cannot be extrapolated to other countries, where no or different vaccine controversies have occurred (Larson et al., 2014). There are few published studies of GPs\' vaccine recommendation behavior for most of the situations examined in our study. In France, François et al. found that 14% of GPs never or sometimes recommend hepatitis B vaccines to adolescents (37% in our study) (François et al., 2011). In Minnesota, McRee et al. found that 24% of health care providers most often do not recommend HPV vaccines to young girls (28% in our study) (McRee et al., 2014). Our findings show that GPs\' vaccine recommendations vary according to the vaccine situation and thus suggest that VH is prevalent among French GPs. The recommendation scores allowed us to capture this hesitancy. GPs\' VH may contribute to the suboptimal vaccine coverage for the vaccines and target groups considered in this study. The absence of physicians\' recommendations has been reported as an important reason for non-vaccination against various vaccine-preventable diseases (Schwarzinger et al., 2010; Holman et al., 2014; Zimmerman et al., 2003). Hesitant physicians are less likely to try to convince hesitant or reluctant patients to be vaccinated. They may also be less likely to address — satisfactorily or at all — patients\' questions about vaccination safety and risks of contracting illnesses, the two reasons patients give most frequently for their own VH (Yaqub et al., 2014). Previous results in France and elsewhere have reported prevalence rates of doubts about vaccine utility ranging between 22% and 37% among physicians (Dubé et al., 2013; François et al., 2011; Bruno et al., 2014). Our findings suggest that such doubts are a stronger factor in GPs\' VH than is their perception of side effects. These doubts may also be linked to a tendency of some GPs to criticize official recommendations and guidelines, for example, because they consider them too constraining and ill adapted to the reality of practice and patients (Clerc et al., 2011). GPs often identify the complexity of the vaccine schedule and its annual modifications for new vaccines and new guidelines as constraints (Larson et al., 2011; François et al., 2011).
