title: Operationalisation of the construct of access to dental care: a position paper and proposed conceptual definitions.
abstract: BACKGROUND
  'Access' is a term readily used in a political and policy context, but one which has not leant itself to measurement of progress towards policy goals or comparisons between health systems. Like 'quality', 'access' is a multi-dimensional construct, but currently often remains a vague and abstract concept which is difficult to translate into something specific, concrete and therefore measureable.
  
  
  METHODS
  The paper describes previous work and identifies a need for a greater consensus and conceptual clarity in the selection of metrics for dental access.
  
  
  RESULTS
  The construct of dental access is described as involving the concepts of 1: opportunity for access; 2, realised access (utilisation); 3, equity and 4, outcomes. Proposed conceptual definitions are given and a case made for measuring 'initial utilisation' separately from 'continued utilisation', reflecting modern approaches which distinguish 'entry access' (gaining entry to the dental care system), from the process of gaining access to higher levels of care. Using a distinction between 'entry access' and 'effective access' allows a choice of whether to restrict measurement to mainly supply side considerations, or alternatively to extend the measurement to include whether there is equity in the proportion of patients who are able obtain effective needed interventions.
  
  
  CONCLUSIONS
  A development of conceptual definitions of dental access could facilitate measurement of progress towards policy goals and operationalisation of the construct.
