question: BACKGROUND: Unscheduled health care constitutes a significant proportion of health‐care utilization. Parental decision making when accessing unscheduled care for their children is multifaceted and must be better understood to inform policy and practice. DESIGN: Nineteen semi‐structured interviews and one focus group (n = 4) with parents of children younger than twelve in Ireland were conducted. Participants had accessed unscheduled care for their children in the past. Data were thematically analysed. RESULTS: Parents accessed unscheduled care for their children after reaching capacity to manage the child's health themselves. This was informed by factors such as parental experience, perceived urgency and need for reassurance. Parents considered the necessity to access care and situated their health‐seeking behaviour within a framework of ‘appropriateness’. Where parents sought unscheduled care was largely determined by timely access, and inability to secure a general practitioner (GP) appointment often led parents to access other services. Parents expressed a need for more support in navigating unscheduled care options. CONCLUSIONS: Better resources to educate and support parents are required, and structural issues, such as accessibility to GPs, need to be addressed to enable parents to better navigate the unscheduled health system and manage their children's health. The discourse around ‘appropriate’ and ‘inappropriate’ access to health care has permeated parental decision making when accessing unscheduled health care for their children. What constitutes appropriate access should be examined, and a shift away from this framing of health‐seeking behaviour may be warranted. PATIENT OR PUBLIC CONTRIBUTION: There was no explicit patient or public involvement. All authors hold experience as users of the health system.
