title: An instrument assessing patient satisfaction with day care in hospitals.
abstract: BACKGROUND
  Patient satisfaction is an important indicator of quality of care in hospitals. Reliable and valid instruments to measure clinical and outpatient satisfaction already exist. Recently hospitals have increasingly provided day care, i.e., admitting patients for one day without an overnight stay. This article describes the adaption of the 'Core questionnaire for the assessment of Patient Satisfaction' (COPS) for general Day care (COPS-D), and the subsequent validation of the COPS-D.
  
  
  METHODS
  The clinical COPS was supplemented with items to cover two new dimensions: Pre-admission visit and Operation Room. It was sent to a sample of day care patients of five general Dutch hospitals to investigate dimensionality, acceptability, reliability, construct and external validity. Construct validity was established by correlating the dimensions of the COPS-D with patients' overall satisfaction.
  
  
  RESULTS
  The COPS-D was returned by 3802 patients (response 46%). Factor analysis confirmed its' structure: Pre-intake visit, Admission, Operation room, Nursing care, Medical care, Information, Autonomy and Discharge and aftercare (extraction communality 0.63-0.90). The internal consistency of the eight dimensions was good (α = 0.82-0.90); the item internal consistency corrected for overlap was satisfactory (>0.40); all inter-item correlations were higher than 0.45 but not too high (<0.90). The construct validity of all dimensions was good (r from 0.52-0.62, p < 0.01). The Information dimension had the strongest correlation with overall day care satisfaction.
  
  
  CONCLUSIONS
  The COPS-D is a reliable and valid instrument for measuring satisfaction with day care. It complements the model of measuring patient satisfaction with clinical and outpatient care given in hospitals. It also fulfils the conditions made while developing the clinical and outpatient COPS: a short, core instrument to screen patient satisfaction.
