Background: People with intellectual disability face numerous barriers to accessing basic preventative health care. This study documents the protocol, process and health outcomes of a multidisciplinary hospital-based Health Care Access Service providing pre-procedure sedation and general anaesthesia for adults with moderate to profound intellectual disability and complexity. Method: In this retrospective quality assurance study, development of the protocol, procedures and outcomes (demographic data, procedures performed and health outcomes) are presented for all patients from commencement of the service for the first 8 month period. Results: Ten people received the service over this time (8 males, 2 females; mean age 30.2 years). Investigation results identified a range of health conditions which are now being appropriately managed. A case study illustrates the process of implementing the protocol, procedures and outcomes, illustrating person-centred and trauma-informed approaches. Conclusions: Service design considerations are discussed from a human rights perspective for future implementation efforts.
