A multifaceted intervention for evidence-based pressure ulcer prevention: a 3 year follow-up

To assess sustainability of an intervention used to implement pressure ulcer prevention.

The Promoting Action on Research Implementation in Health Service, framework was used to develop an intervention aimed to implement evidence-based pressure ulcer prevention in a hospital setting. A short-term follow-up showed that significantly more patients received pressure ulcer prevention. A qualitative process evaluation gave support that the intervention and the implementation process changed the understanding and approach to working with pressure ulcer prevention from treating to preventing.

The study had a sequential mixed method approach, combining quantitative and qualitative data. For the quantitative data, baseline and short-term follow-up (6-8 months) data reported in an initial study were compared with long-term follow-up (36-42 months) data (n = 259 patients). For the qualitative data, interviews with registered nurses (n = 20), assistant nurses (n = 7) and first-line managers (n = 5) were performed.

The performance of pressure ulcer prevention was sustained 3 years from its conception. The number of patients with pressure ulcers was reduced (P = 0.021). Systematic work with quality measurements, support from first-line managers, internal facilitation, collaboration and pressure ulcer prevention skills could explained the sustainability. Obstacles to achieve high-quality pressure ulcer prevention were inadequate communication, high workloads and high rates of new and substitute nurses.

Three different components for sustainability on the micro-level are described; benefits for the patients, the need for routinization and development over time. Threats to sustainability are described as factors on the macro-level. There needs to be collaboration in the healthcare organization from the micro-to-macro levels, and committed experienced nurses are needed to obtain high-quality sustainable pressure ulcer prevention.
