BACKGROUND: Negative-pressure wound therapy with instillation is a novel wound therapy that combines negative pressure with instillation of a topical solution. METHODS: This retrospective, historical, cohort-control study examined the impact of negative-pressure wound therapy with and without instillation. RESULTS: One hundred forty-two patients (negative-pressure wound therapy, n = 74; therapy with instillation, 6-minute dwell time, n = 34; and therapy with instillation, 20-minute dwell time, n = 34) were included in the analysis. Number of operative visits was significantly lower for the 6- and 20-minute dwell time groups (2.4 ± 0.9 and 2.6 ± 0.9, respectively) compared with the no-instillation group (3.0 ± 0.9) (p ≤ 0.05). Hospital stay was significantly shorter for the 20-minute dwell time group (11.4 ± 5.1 days) compared with the no-instillation group (14.92 ± 9.23 days) (p ≤ 0.05). Time to final surgical procedure was significantly shorter for the 6- and 20-minute dwell time groups (7.8 ± 5.2 and 7.5 ± 3.1 days, respectively) compared with the no-instillation group (9.23 ± 5.2 days) (p ≤ 0.05). Percentage of wounds closed before discharge and culture improvement for Gram-positive bacteria was significantly higher for the 6-minute dwell time group (94 and 90 percent, respectively) compared with the no-instillation group (62 and 63 percent, respectively) (p ≤ 0.05). CONCLUSION: The authors' results suggest that negative-pressure wound therapy with instillation (6- or 20-minute dwell time) is more beneficial than standard negative-pressure wound therapy for the adjunctive treatment of acutely and chronically infected wounds that require hospital admission. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.
