title: Evaluation of the personal dental services (wave 1) for Lambeth, Southwark and Lewisham primary care trusts--Part 1: Retrospective analyses of registration data and access issues.
abstract: OBJECTIVE
  The purpose of the study was to undertake analyses of registration data for the personal dental services (PDS) of Lambeth, Southwark and Lewisham primary care trusts and relate the analyses to the PDS goal of increasing uptake of dental services.
  
  
  METHODS
  Secondary analyses of registration statistics provided by the Dental Practice Board were undertaken for both 1 years pre-PDS (October 1997 to September 1998) and post-PDS (October 1998 to March 2003) periods. Three sets of analyses were undertaken to consider different aspects of changing registrations: (1) Absolute numbers of patients registered at each time interval; (2) Rates of change in numbers of patients registered for the entire period after the introduction of PDS; and (3) Rates of change in numbers of patients registered for the most recent 3 years of available data.
  
  
  RESULTS
  There was a significant increase in the numbers of children registered under capitation, post-PDS as compared to the pre-PDS level (all ages and both genders combined). Post-PDS, the rate of increase for the children was approximately one additional child per practice per month (0.96, 95% CI 0.41-1.52). Similarly there was a significant trend for increasing adults registrations over time of about two and a half adults per practice per month (2.42, 95% CI 0.90-3.95). There was no evidence of a change in registrations for children or adults in total over the most recent period of 3 years.
  
  
  CONCLUSIONS
  The analysis of the absolute numbers of registered patients each month indicated that the PDS practices had more children registered than before the implementation of the PDS scheme, but not adults. Overall post-implementation there was a trend for increasing registrations in both children and adults, but the most recent data indicated a plateau effect. Further consideration of facilitators to achieve PDS goals of improved uptake of services is required, particularly as they relate to local contexts.
