Health economic burden that different wound types impose on the UK's National Health Service

The aim of this study was to estimate the patterns of care and annual levels of health care resource use attributable to the management of different wound types by the UK's National Health Service (NHS) in 2012/2013 and the annual costs incurred by the NHS in managing them. This was a retrospective cohort analysis of the records of 2000 patients in The Health Improvement Network (THIN) Database. Patients' characteristics, wound-related health outcomes and all health care resource use were quantified, and the total NHS cost of patient management was estimated at 2013/2014 prices. The NHS managed an estimated 2.2 million patients with a wound during 2012/2013. Patients were predominantly managed in the community by general practitioners (GPs) and nurses. The annual NHS cost varied between 1.94 pound billion for managing 731 000 leg ulcers and 89.6 pound million for managing 87 000 burns, and associated comorbidities. Sixty-one percent of all wounds were shown to heal in an average year. Resource use associated with managing the unhealed wounds was substantially greater than that of managing the healed wounds (e.g. 20% more practice nurse visits, 104% more community nurse visits). Consequently, the annual cost of managing wounds that healed in the study period was estimated to be 2.1 pound billion compared with 3.2 pound billion for the 39% of wounds that did not heal within the study year. Within the study period, the cost per healed wound ranged from 698 pound to 3998 pound per patient and that of an unhealed wound ranged from 1719 pound to 5976 pound per patient. Hence, the patient care cost of an unhealed wound was a mean 135% more than that of a healed wound. Real-world evidence highlights the substantial burden that wounds impose on the NHS in an average year. Clinical and economic benefits to both patients and the NHS could accrue from strategies that focus on (a) wound prevention, (b) accurate diagnosis and (c) improving wound-healing rates.
