Influenza vaccination: A qualitative study of practice level barriers from medical practitioners caring for children with special risk medical conditions.

BACKGROUND

Understanding the influenza vaccination practices of general practitioners (GP) and paediatric hospital specialists caring for children with special risk medical conditions (SRMC) is imperative for designing interventions to improve uptake. This study aimed to identify the vaccination decision making, provider practices and perceived barriers and facilitators to recommending or delivering influenza vaccine for children with SRMCs at the tertiary and primary care levels.

METHODS

Nominated GPs and hospital specialists from a single tertiary hospital were interviewed to explore influenza vaccination practices and challenges for children with confirmed SRMCs. Interviews were digitally recorded, transcribed verbatim and thematic analysis was used to inductively code these data. Resulting themes were mapped across the COM-B ('capability', 'opportunity', 'motivation' and 'behaviour') theoretical framework to understanding barriers and potential interventions.

RESULTS

Twenty-six medical practitioners (21 GPs and 5 hospital specialists) completed semi-structured interviews. Barriers, and facilitators for influenza vaccine recommendation (the intended behaviour) were thematically grouped. Opportunity themes included structural barriers (e.g. limited use of systems and processes to support the identification of children with SRMCs); recommendation as standard practice; vaccination inconvenience; lack of communication and educational resources; social acceptance and normalisation; and media messaging. Capability themes included provider communication with parents; knowledge of influenza vaccine recommendations; and professional boundaries to implement the recommendation. Themes in the Motivation category included provider clinical prioritisation and responsibility towards providing a recommendation.

CONCLUSIONS

The main barriers to influenza recommendation raised by our study participants were structural. These included lack of processes to identify children with SRMCs, limited use of reminder systems and unclear delineation of role responsibility between hospital specialists and GPs. An important driver that emerged was GPs' responsibility for providing a recommendation. To increase influenza vaccine coverage for children with SRMCs, consideration should be given to addressing practice level structural barriers and improving collaboration.
