title: Fee-paying systems and service patterns in a Hong Kong dental clinic.
abstract: OBJECTIVE
  This study aimed to describe and compare patients' consumption of dental services and dentists' productivity in a university campus clinic before and after changing from a time-based to an item-based fee-paying system.
  
  
  METHODS
  Data were collected from the University of Hong Kong dental clinic which serves all university students and staff. A time-based fee-paying system had been in use up to February 1999 when it was switched to an item-based system. Computerised records of all patients in two 1-year periods starting from February 1996 and February 1999 were analysed.
  
  
  RESULTS
  The percentages of eligible users who attended the University dental clinic were similar in the two study periods (30% in 96/97 vs 29% in 99/00). However, on average, patients consumed more dental service items in a year after the switch in fee-paying system (3.2 vs 4.1). There was also an increase in the mean number of dental service items provided by a dentist per working week after the change in fee-paying system (71.5 vs 99.4).
  
  
  CONCLUSIONS
  On switching from a time-based to an item-based fee-paying system, dentists in the UHS dental clinic became more productive and the consumption of dental services per patient also increased.
