What Facilitates and Hinders the Implementation of Nurse-Led Interventions in Long-Term Dementia Care? A Qualitative Interview Study With Swiss Nursing Experts and Managers

Background: To support the implementation of nurse-led interventions in long-term dementia care, in-depth knowledge of specific supporting factors and barriers is required. Conditions and structures of caring for people with dementia differ widely, depending on the country and the care context. Our study aimed to describe the experiences and opinions of nursing experts and managers with regard to facilitators and barriers to the implementation of nurse-led interventions in Swiss long-term dementia care. Methods: We conducted a qualitative descriptive study using individual interviews based on qualitative vignettes as a useful stimulus to generate narrations allowing to study peoples’ perceptions and beliefs. The study took place in nursing homes in the German-speaking part of Switzerland and in the Principality of Liechtenstein using purposive sampling. We intended to conduct the interviews face-to-face in a quiet room according to the participant’s choice. However, due to the lockdown of nursing homes during the COVID-19 pandemic in spring 2020, we performed interviews face-to-face and by video. We analysed data thematically following Braun and Clarke to achieve a detailed, nuanced description. To verify our interpretation and to ensure congruence with participants’ perspectives, we conducted member checks. The Standards for Reporting Qualitative Research (SRQR) served to structure our manuscript. Results: Six dyads of nursing home managers and nursing experts from six nursing homes took part in our study (n=12). Our thematic analysis yielded seven themes reflecting facilitators and barriers to implementing nurse-led interventions in Swiss long-term dementia care: «A common attitude and cohesion within the organization», «Commitment on several levels», «A needs-oriented implementation», «The effect and the public perception of the intervention», «A structured and guided implementation process», «Supporting knowledge and competencies», as well as «Resources for implementing the intervention». Conclusions: Successful implementation of nurse-led interventions in dementia care is highly challenging due to the complex nature of interventions. Therefore, it is important to know the facilitators and barriers to optimally design implementation strategies. Our results might support researchers and other key persons involved in implementing nurse-led interventions in Swiss long-term dementia care.
