Type of Study

Mixed-methods process evaluation embedded in a cluster randomised controlled trial (7 intervention homes in Belgium)


PICO Summary

Population (P)

  • Staff in seven nursing homes in Flanders, Belgium
  • Included management, nurses, care assistants, allied health professionals, and non-clinical staff (e.g., cleaners, admin)
  • Secondary focus on nursing home residents and family members as beneficiaries of staff-delivered ACP

Intervention (I)

  • ACP+ intervention
    • An 8-month, multi-component, theory-informed program designed to integrate advance care planning into daily nursing home practice
    • Involved:
      • Role-based training (Reference Persons, Facilitators, Antennas)
      • Monthly multidisciplinary meetings
      • Audit and feedback
      • Practical coordination
      • Shadowing, coaching, and follow-up from external trainers
      • Tailored organisational protocols and policy creation

Comparison (C)

  • Not directly evaluated in this article (as this is a process evaluation of the intervention arm only). However, the overarching cluster RCT included a control group receiving usual care (not reported here).

Outcomes (O)

Person-centred outcomes:

  • Not directly measured in this process evaluation (focus was on staff implementation and organisational outcomes)

Process outcomes:

  • Dose, reach, fidelity, adaptations of intervention delivery
  • Staff training attendance: only 33% of eligible staff attended (range 6%–69%) 
  • Implementation adaptations: 5 of 7 homes adapted activities; e.g., added coordinators, shortened sessions
  • Organisational policy creation: all homes developed an internal ACP protocol

Health system/organisational outcomes:

  • Increased awareness and systematisation of ACP across staff roles
  • Perceived cultural shift toward integrating ACP into everyday care
  • Barriers: time constraints, high turnover, staff absences, lack of GP involvement

Findings Summary

  • While the ACP+ intervention was well received, staff engagement was limited due to systemic barriers
  • Mechanisms for positive change included management supportclear staff roles, and accessible training
  • Organisational culture was key to success; some trial effects (e.g., increased ACP conversations) were not captured by quantitative outcomes alone
  • This evaluation underscores the importance of contextual, cultural, and team-based factors in the successful implementation of ACP in care homes
