Primary care in accident and emergency departments : the cost effectiveness and applicability of a new model of care.

Doctoral thesis English OPEN
Dale, Jeremy

The thesis describes the development, research and evaluation of the applicability of a new\ud model of care that involves GPs being employed on a sessional basis in A&E departments to\ud treat patients attending with primary care needs. The main aim of the study was to research its\ud cost and clinical effectiveness.\ud A multi-faceted approach was taken to include consideration of patients' needs and preferences,\ud professional concerns, organisational and structural issues within the health service, and\ud planning and policy issues. Clinical, sociological, epidemiological, and economic perspectives\ud are drawn upon, reflecting the context of the service development and to provide a firm base\ud for discussion about the generalisability and applicability of the findings.\ud The first two chapters provide a detailed review of the epidemiological, sociological,\ud clinical, and organisational literature relating to the primary care/A&E interface. The\ud incentives and disincentives that may act to increase or reduce demand and supply are\ud explored, in addition to issues relating to the 'appropriateness' of demand, the\ud organisational culture of A&E departments, and strategies used to curtail or cope with\ud demand. The demand for primary care at A&E departments appears to cross national\ud boundaries and hence, literature from other countries (particularly the USA) is included\ud and its applicability to the UK considered. Relevant literature relating to the quality of A&E\ud care, patient satisfaction, and the costing of care is also discussed.\ud The main study was a prospective controlled trial that was conducted at King's College\ud Hospital. This compared process variables, clinical outcome and costs of 'primary care'\ud consultations performed by senior house officers (SHOs), registrars, and general\ud practitioners working three-hour sessions in A&E. A new system of nurse triage was\ud implemented to allow the prospective identification of patients presenting with primary care\ud needs. A total of 27 SHOs, three registrars and one senior registrar were included, and the\ud patient sample comprised 1702 patients seen by GPs, 2382 by SHOs, and 557 by registrars or\ud the senior registrar. GPs were found to practice considerably less interventionist care than\ud A&E medical staff, and the resource implications were substantial.\ud The findings are discussed critically, and their applicability is considered drawing on empirical\ud data from recent evaluations of A&E Primary Care Service developments in other parts of\ud London. The policy and service implications of the study are considered and further research\ud needs identified.
