title: Efficacy of person-centred care as an intervention in controlled trials - a systematic review.
abstract: OBJECTIVE
  To identify person-centred care as an intervention in controlled trials, where patients had been involved as a partner, and to describe the outcomes of these studies.
  
  
  BACKGROUND
  The notion of person-centred care asserts that patients are persons and partners in care and should not be reduced to their disease alone.
  
  
  METHODS
  A systematic literature review.
  
  
  METHODS
  Searches were undertaken in the databases PUBMED and CINAHL. The inclusion criteria were that person-centred care as an intervention was described as a partnership between the caregiver and the patient, and that the studies were randomised controlled trials or quasi-experimental designs. The studies were analysed based on methodology, context and type of intervention, outcomes and effects of the interventions. Eleven trials fulfilled the inclusion criteria.
  
  
  RESULTS
  The studies were carried out in a variety of contexts with diverse outcomes. Person-centred care as an intervention was shown to be successful in eight of the studies. The internal and external validity in the studies were generally good. However, as regards the precision of the studies there was a wide variation.
  
  
  CONCLUSIONS
  The value and efficacy of person-centred care as an intervention have only been studied to a limited extent. Methodological problems in trial design and execution could account for the general lack of research on person-centred care. Evidence that person-centred care is effective is insufficient, more stringent studies are needed.
  
  
  CONCLUSIONS
  The results suggest that person-centred care may lead to significant improvements, but the implementation and relevant effects needs to be assessed in more studies.
