The Delivery of care domain contains variables related to health care interventions, including compliance, withdrawal and satisfaction. These variables are grouped within the same domain as they are all related to the appropriateness and acceptability of the intervention and may not be easily distinguishable (for example, because of overlap between issues relating to compliance, satisfaction with care, withdrawal, treatment failure).
Examples of outcomes in this category include patient preference; withdrawal from intervention (e.g. time to treatment failure); appropriateness, accessibility, quality and adequacy of intervention; patient or carer satisfaction; and process, implementation and service outcomes.
Technical aspects of surgery should be classified within the Delivery of care domain, as they relate to the delivery of intervention. Outcomes such as "conversion to open surgery" indicate failure of intervention, which is included within this domain.
