title: ﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿Negative pressure wound therapy - a descriptive study.
abstract: ﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿ To address a persistent lack of evidence regarding the clinical outcomes of negative pressure wound therapy (NPWT) and identify which patient groups are most likely to benefit from NPWT, a retrospective, descriptive study was conducted to describe outcomes of this treatment modality when used in clinical practice. Charts from a consecutive series of 87 patients (median age 68 years, range 16 - 92 years) who received NPWT during a period of 24 months were abstracted to a statistical software file. Patient demographics, history, and comorbidity variables as well as treatment outcomes were obtained from the computerized in- and outpatient record system. Treatment outcomes were grouped as successful (goal of care was met) or not successful (goal of care was not met). Successful treatment was noted for a total of 62 patients (71%) with a median treatment time of 17 days. The proportion of patients with a successful outcome was significantly higher in patients with infectious, postoperative, and traumatic wounds than in patients with wounds related to peripheral vascular disease or pressure ulcers (P = 0.001). Treatment complications were observed in 18 patients (21%); five were related to infection. Quality-of-life concerns were noted as a reason for stopping treatment in four patients and equipment problems were recorded for two patients receiving NPWT in the home. This study confirms previous re- search that NPWT may be an effective and safe treatment method for acute wounds but further studies are needed to evaluate treatment efficacy and effectiveness in patients with peripheral vascular disease or pressure-induced wounds. Results also suggest that research protocols should include patient quality-of-life outcomes.
