IntroductionIn care settings across the globe non-clinical staff are involved in filtering patients to the most appropriate source of care. This includes primary care where general practice receptionists are key in facilitating access to individual surgeries and the wider National Health Service. Despite the complexity and significance of their role little is known of how the decision-making behaviors of receptionists impact policy implementation and service delivery. By combining the agent-based implementation theory of street-level bureaucracy with a tri-level analytical framework this work acknowledges the impact of the decisions made by receptionists as street-level bureaucrats and demonstrates the benefits of using the novel framework to provide practical insight of the factors influencing those decisions. MethodsA secondary analysis of qualitative data gathered from a series of semi-structured interviews conducted with 19 receptionists in the United Kingdom in 2019 was used to populate a tri-level framework: the micro-level relates to influences on decision making acting at an individual level, the meso-level influences at group and organizational levels, and the macro–level influences at a societal or policy level. ResultsAt the micro-level we determined how receptionists are influenced by the level of rapport developed with patients and would use common sense to interpret urgency. At the meso-level, influences included their position at the forefront of premises, the culture of the workplace, and the processes and protocols used by their practice. At the macro-level, participants described the impact of limited health service capacity, the lack of mandatory training, and the growth in the use of digital technologies. ConclusionsStreet-level bureaucracy, complemented with a tri-level contextual analysis, is a useful theoretical framework to understand how health workers, such as receptionists, attempt to provide universality without sufficient resource, and could potentially be applied to other kinds of public service workers in this way. This theoretical framework also benefits from being an accessible foundation on which to base practice and policy changes.
