title: [Cause of non-pertinent hospital stays: interobserver concordance using the French version of the Appropriateness Evaluation Protocol].
abstract: BACKGROUND
  The modified French version of the Appropriateness Evaluation Protocol (AEPf) has been validated. Inappropriate days according to simple medical and technical criteria are identified with this tool. The aim of this study is to highlight the interest of investigating the reasons for inappropriate days and to assess the inter-observers reliability of the questionnaire developed for this purpose.
  
  
  METHODS
  This questionnaire collects on one hand the needs of patients - distinguishing health care and accommodation needs - and on the other hand the reasons for inappropriate hospital days. The data were collected from January to September 1998 in nine voluntary medical and surgical departments. For each day of study randomly selected, each inappropriate hospital day according to AEPf has been included. Data were collected by two health professionals (a nurse and a physician), using a concurrent design.
  
  
  RESULTS
  The reliability of the over-ride option of the appropriateness assessment of the 345 hospital days was good (overall Kappa coefficient: 0.66; 95% CI: 0.55-0.78). The comparison of the two expert judgments on health care needs fulfilled during the hospital day was acceptable; the Kappa coefficient was 0.62 (95% CI: 0.52-0.72). The reliability of expert assessment on patient accommodation needs (home, housing facilities or hospital) was good (Kappa coefficient: 0.67; 95% CI: 0.60-0.75). When hospital was not the accommodation the most adapted for patient, the reliability of the reasons for inappropriate days was high (Kappa coefficient: 0.75; 95% CI: 0.61-0.80). Kappa coefficients were different between hospitals, indicating a center effect.
  
  
  CONCLUSIONS
  This instrument has been found to be reliable and should be used in complement of the first part of the AEPf which assess the prevalence of inappropriate days. It might help to detect dysfunctions within or outside the hospital and thus be used for evaluation or planning of health care.
