Clinical and economic consequences of discharge from hospital with on-going TNP therapy: a pilot study.

Despite practical advantages (such as exudate management and reduced dressing changes) the adoption of topical negative pressure therapy (TNP) in home care may be restricted through logistical issues and a perception that the intervention is more expensive than the more traditionally utilised wound management products. This pilot study followed the experiences of 20 subjects with a variety of acute and chronic wounds who received TNP either in hospital (n=10), at home (n=5) or in both care settings (n=5). All except one subject showed both reductions in wound surface area and improved appearance of the wound bed during the course of treatment ranging from 2 to 74 days. The single subject, where a deterioration in their wound was noted, had presented with an unclear wound diagnosis thus highlighting the absolute need for accurate diagnosis of wound aetiology prior to commencement of any treatment regime. The cost of treatment was lower where subjects were treated at home (mean cost per day pound45.9 SD: 17.0) and highest where care was delivered exclusively in hospital (mean cost per day pound259.1 SD: 2.8). Direct comparison of these data with other published studies on the use of TNP therapies is obviously restricted through regional differences in the cost of nursing care, patterns of use of the TNP consumables and the wound outcomes followed in individual cases, however, there would appear to be a qualitative and economic benefit from home care.
