RESUMEN
PURPOSE: To identify and describe the strategies and processes used by multidisciplinary teams of health care professionals to reduce surgical site infections (SSIs). MATERIALS AND METHODS: An integrative review of the research literature was undertaken. Searches were conducted in April 2015. Following review of the included studies, data were abstracted using summary tables and the methodological quality of each study assessed using the Standards for Quality Improvement Reporting Excellence guidelines by two reviewers. Discrepancies were dealt with through consensus. Inductive content analysis was used to identify and describe the strategies/processes used by multidisciplinary health care teams to prevent SSI. RESULTS AND DISCUSSION: In total, 13 studies met the inclusion criteria. Of these, 12 studies used quantitative methods, while a single study used qualitative interviews. The majority of the studies were conducted in North America. All quantitative studies evaluated multifaceted quality-improvement interventions aimed at preventing SSI in patients undergoing surgery. Across the 13 studies reviewed, the following multidisciplinary team-based approaches were enacted: using a bundled approach, sharing responsibility, and, adhering to best practice. The majority of studies described team collaborations that were circumscribed by role. None of the reviewed studies used strategies that included the input of allied health professionals or patient participation in SSI prevention. CONCLUSION: Patient-centered interventions aimed at increasing patient participation in SSI prevention and evaluating the contributions of allied health professionals in team-based SSI prevention requires future research.
RESUMEN
PURPOSE: Negative-pressure wound therapy (NPWT) is increasingly used for primary surgical incisions despite the paucity of evidence. Study objectives were to assess the use of NPWT on surgical sites to prevent infections and other wound complications after elective primary hip arthroplasty and to consider feasibility of a larger trial. METHODS: A nonmasked, randomized controlled pilot trial. Patients were recruited preoperatively from the preadmission clinic of an Australian hospital during 2013-2014. Computer-generated randomization was performed with allocation concealed until completion of surgery. The intervention group received NPWT (PICO) while the control group received the standard care hydrocolloid, reinforced with 2 absorbent dressings. Patients were followed for 6 weeks for postoperative complications (infection, length of stay, readmission) and skin complications (bruising, seroma, hematoma, dehiscence). Feasibility end points included numbers recruited, randomized, and followed up; fidelity; and costs. RESULTS: Of 77 people approached, 76 were recruited, and 70 were randomized. Of 35 in the negative-pressure group, 2 received the standard dressing. Attrition at 6 weeks exceeded 10% in both groups. Dressing costs were lower in the control group ($3.01/d vs $38.40/d); SSI incidence was 2/35 in the NPWT and 3/35 in the control group (intention to treat: risk ratio [RR] = 0.67; 95% confidence interval [CI] = 0.12-3.7; P = .65). NPWT patients experienced more postoperative wound complications (RR = 1.6; 95% CI = 1.0-2.5; P = .04). CONCLUSION: A reduction of 3% in SSI incidence suggests that a definitive trial requires approximately 900 patients per group. Yet there is uncertainty around the benefit of NPWT after elective hip arthroplasty.
