Background: Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are common surgical procedures but carry a risk of harmful and costly surgical site complications (SSCs). This systematic review and meta-analysis examined the impact of closed incision negative pressure therapy (ciNPT) on the risk of SSCs following THA and TKA. Methods: A systematic literature review identified studies published between January 2005 and July 2021 comparing ciNPT (Prevena Incision Management System) to traditional standard-of-care dressings for patients undergoing THA and TKA. Meta-analyses were performed using a random effects model. A cost analysis was conducted using inputs from the meta-analysis and cost estimates from a national database. Results: Twelve studies met the inclusion criteria. Eight studies evaluated SSCs, where a significant difference was seen in favor of ciNPT (relative risk [RR]: 0.332, P < .001). Significant benefits in favor of ciNPT were also observed for surgical site infection (RR: 0.401, P = .016), seroma (RR: 0.473, P = .008), dehiscence (RR: 0.380, P = .014), prolonged incisional drainage (RR: 0.399, P = .003), and rate of return to the operating room (RR: 0.418, P = .001). The estimated cost savings attributed to ciNPT use was $932 per patient. Conclusions: The use of ciNPT after TKA and THA was associated with a significant reduction in the risk of SSCs, including surgical site infections, seroma, dehiscence, and prolonged incisional drainage. The risk of reoperation was reduced as were the costs of care in the modeled cost analysis, suggesting a potential for both economic and clinical advantages for ciNPT over standard-of-care dressings, particularly in high-risk patients.

Purpose: Previous studies on the repair of small umbilical hernias have suggested a lower recurrence rate with mesh compared to suture repair. An important question is in what anatomical position the mesh should be placed. The purpose of this study was to investigate the outcome of using a standardized 4 × 4 cm onlay-mesh for umbilical hernias ≤ 2 cm.Methods: A retrospective study was conducted at a single centre in Sweden on all umbilical hernia repairs during 2015-2019. The follow-up time was at least four months. Patients were identified using the hospital medical database. Repairs performed with suture or a sublay, ventral patch and laparoscopic mesh positioning were excluded. The patient's demographics, comorbidities, intra-and post-operative details were considered. The primary outcome was surgical site complications within 30 days. The secondary outcome was a recurrence.Results: 80 patients were repaired with a small onlay-mesh for an umbilical hernia ≤ 2 cm. The median (range) follow-up time was 29.0 (4.3-50.1) months. The median age was 46 (26-76) years old. The median body mass index was 28 (19-38) kg/m2. The male to female ratio was 2:1. 4 patients were identified with a surgical site post-operative complication; three with seromas and one with a superficial wound infection. 3 of these were given antibiotics. 2 patients were treated with wound openings bedside. There were no registered cases of recurrence.Conclusions: Repairing small umbilical hernias with a small onlay-mesh was safe with a low surgical site complication rate. Randomized trials are needed to assess whether mesh can reduce recurrences in umbilical hernia repairs ≤ 2 cm. [ABSTRACT FROM AUTHOR]

Background: The direct anterior (DA) approach to total hip arthroplasty (THA) is associated with higher rates of surgical site complications (SSCs) compared to other approaches, particularly among high-risk patients. Closed incision negative pressure therapy (ciNPT) is effective in reducing SSCs and surgical site infections (SSIs) in other populations. We asked whether ciNPT could decrease SSCs in high-risk patients undergoing DA THA.Methods: This prospective randomized controlled trial (RCT) enrolled high-risk DA THA patients at 3 centers. Patients were offered enrollment if they had previously identified risk factors for SSC: Body mass index (BMI) >30 kg/m2, diabetes, active smoking, or before hip surgery. Patients were randomized after closure to either an occlusive (control) dressing or ciNPT dressing for 7 days. All 90-day SSCs were recorded. A priori power analysis demonstrated 116 patients were required to identify a 4.5x relative reduction in SSCs. Chi-square tests were used to evaluate probability of complications.Results: One hundred and twenty two patients enrolled; 120 completed data collection. SSCs occurred in 18.3% (11/60) of control patients compared to 8.3% (5/60) of ciNPT patients (χ2 = 2.60, P = .107). SSCs included dehiscence to the subcutaneous level (13) and prolonged drainage (3). Nine control (15.0%) and 2 ciNPT (3.3%) patients met CDC criteria for superficial SSI (χ2 = 4.90, P = .027). Fifteen of 16 SSCs resolved with local wound care. One in the ciNPT group required reoperation for acute PJI.Conclusion: Among patients at risk of surgical site complications undergoing DA THA, we identified a significant reduction in superficial SSIs and a trend toward lower overall SSCs with ciNPT.

Background: The PROMISES (Post-market, Randomized, Open-Label, Multicenter, Study to Evaluate the Effectiveness of Closed Incision Negative Pressure Therapy Versus Standard of Care Dressings in Reducing Surgical Site Complications in Subjects With Revision of a Failed Total Knee Arthroplasty) randomized controlled trial compared closed incision negative pressure therapy (ciNPT) to standard of care (SOC) after revision total knee arthroplasty in high-risk patients. We assessed the costs associated with 90-day surgical site complications (SSCs) to determine the cost-benefit of ciNPT.Methods: A health economic model was used to determine mean per-patient costs to manage the surgical site, including the costs of postoperative dressings, surgical and non-surgical interventions, and readmission. A subanalysis was performed to examine cost-benefit in "lower risk" (Charlson Comorbidity Index < 2) and "higher risk" (Charlson Comorbidity Index ≥ 2) patients.Results: Patients with ciNPT experienced fewer SSCs (3.4% vs 14.3%; P = .0013) and required fewer surgical (0.7% vs 4.8%; P = .0666) and non-surgical (2.7% vs 12.9%; P = .0017) interventions compared to those with SOC. Readmission rates were significantly higher when patients experienced SSC (31% vs 4%; P = .0001). Using the economic model, respective per-patient costs for the ciNPT and SOC groups were $666 and $52 for postoperative dressings, $135 and $994 for surgical interventions, $231 and $970 for readmissions, and $15 and $70 for non-surgical interventions. Total per-patient costs for surgical site management were $1,047 for ciNPT and $2,036 for SOC. Among the lower risk population, mean per-patient cost was $1,066 for ciNPT and $1,474 for SOC. Among the higher risk population, mean per-patient cost was $676 for ciNPT and $3,212 for SOC.Conclusion: Despite higher upfront costs for postoperative dressings, ciNPT was cost-effective in this health economic model, decreasing the costs of surgical site management after revision total knee arthroplasty by 49% in this study population and 79% in higher risk subgroup.

Objective: Surgical site complications (SSCs) such as dehiscence and infection are a common issue within vascular surgeries and are a key concern to payers and clinicians. It is estimated that occurrence of complications in vascular surgery can increment length of stay by 9.72 days and costs by £3776 per episode. The objective of this research was to determine the clinical and economic impact of the prophylactic use of single use negative pressure wound therapy (sNWPT) in postoperative femoral endarterectomy incisions within a single centre in the Netherlands. Method: Data were extracted retrospectively from the medical notes of patients consecutively treated for femoral endarterectomy between January 2013 and December 2019 in a single centre in the Netherlands. Since August 2016, patients were treated with the sNPWT device and their data were compared with that of patients treated before the introduction of the device. Data were extracted on SSCs and associated healthcare resource use, with comparisons made between the two patient groups. Results: The study included a cohort of 108 patients. Data of patients treated by standard care (n=64) showed 32 (50%) patients developed complications. This reduced significantly in patients treated with the sNPWT device (n=44) of whom eight (18.2%) developed a postoperative complication (p=0.0011). Average postoperative costs per patient were €3119 for those in the standard care group and €2630 where the sNPWT device was used. Conclusion: sNPWT provided clinical and economic benefits over standard care in the treatment of femoral endarterectomy patients, significantly reducing rate of complication and their associated costs.

The present study aimed to assess the economic and organizational implications of a portable device for negative-pressure wound therapy (NPWT) implementation, compared with the administration of pharmacological therapies alone for preventing surgical complications in patients undergoing general, cardiac, obstetrical–gynecological, or orthopedic surgical procedures.Patients and methods: A total of 8,566 hospital procedures, related to the year 2015 from one hospital, were evaluated considering infection risk index, occurrence rates of SSCs, drug therapies, and surgical, diagnostic, and specialist procedures and hematological exams. Activity-based costing and budget impact analyses were implemented for the economic assessment.Results: Patients developing an SSC absorbed i) 64.27% more economic resources considering the length of stay (€ 8,269±2,096 versus € 5,034±2,901, p

Surgical site infections (SSIs) contribute to increased patient morbidity, prolonged hospital stays, and substantial healthcare costs. Prophylactic antibiotics play a pivotal role in mitigating the risk of SSIs, with their administration being a standard practice before both emergency and elective surgeries. This paper provides a comprehensive review and comparative analysis of the benefits of prophylactic antibiotic administration in emergency surgery versus elective surgery. Through a systematic literature review and analysis of relevant studies identified through PubMed searches, this paper highlights the specific benefits of prophylactic antibiotics between emergency and elective surgeries. The findings underscore the importance of tailored antibiotic regimens and administration protocols to optimize patient care and promote successful surgical outcomes in diverse clinical settings. Further research is warranted to refine guidelines and enhance understanding of the relationship between prophylactic antibiotics and surgical outcomes across different surgical contexts., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Meretsky et al.)

Early surgical education is required for neurosurgical residents to learn many surgical procedures. However, the participation of less experienced residents may increase perioperative complication rates. Perioperative complication studies in the field of neurosurgery are being increasingly published; however, studies have not yet focused on cervical laminoplasty. The study population included 193 consecutive patients who underwent cervical laminoplasty in Tokyo Metropolitan Neurological Hospital between 2008 and 2014. Patient and surgeon background factors, as well as perioperative complication rates were retrospectively compared between resident and board-certified spine neurosurgeon groups. Deteriorated or newly developed neurological deficits and surgical site complications within 30 days of cervical laminoplasty were defined as perioperative complications. Out of 193 patients, 123 (64%) were operated on by residents as the first operator and 70 (36%) by board-certified spine neurosurgeons. No significant differences were observed in patient and surgeon factors between the two groups, except for hyperlipidemia (13 vs 17, p = 0.02). Furthermore, no significant differences were noted in perioperative complication rates between the two groups (7 [5.7%] vs 4 [5.7%], p = 1). Cervical laminoplasty performed in a standardized manner by residents who received their surgical training in our hospital did not increase perioperative complication rates, and ensured the safety of patients.

Closed incision negative pressure therapy (ciNPT) has been adopted into practices of diverse surgical specialties to help reduce postsurgical complication risks. There are two primary commercially available systems that deliver ciNPT through different mechanisms. The purpose of this meta-analysis is to compare the potential effects of two different ciNPT systems on clinical outcomes following hip and knee arthroplasty. A systematic literature search was conducted to identify hip and knee arthroplasty studies comparing the incidence of surgical site infections (SSIs) and surgical site complications (SSCs) versus standard of care (SOC) following the use of two different ciNPT systems. Four meta-analyses were performed by calculating risk ratios (RR) to assess the effect of (1) ciNPT with foam dressing (ciNPT-F) versus SOC and (2) ciNPT with multilayer absorbent dressing (ciNPT-MLA) versus SOC. Comprehensive Meta-Analysis Version 3.0 (Biostat Inc., Englewood, NJ) software was used to perform the analyses. Twelve studies comparing ciNPT-F to SOC and six studies comparing ciNPT-MLAto SOC were analyzed. SSI rates were reported in seven of 12 studies involving ciNPT-F. In those, ciNPT-F significantly reduced the incidence of SSI (RR = .401, 95% confidence interval (CI) = .190, .844; p = .016). Across four of six studies that reported SSI rates, there was no significant difference in SSI rates between ciNPT-MLAvs SOC (RR = .580, 95% CI = .222, 1.513; p = .265). SSC rates were evaluated in eight of 12 ciNPT-F studies that reported SSC rates. This meta-analysis of the eight ciNPT-F studies showed significantly reduced SSC rates with ciNPT-F vs SOC (RR = .332, 95% CI = .236, .467; p < 0.001). For ciNPT-MLA, five of six studies reported SSC rates. In those, there was no significant difference in SSC rates between ciNPT-MLA vs SOC (RR = .798, 95% CI = .458, 1.398; p = .425). These meta-analyses results showed a significant reduction in SSI and SSC rates in the ciNPT-F group vs SOC and no difference in SSI and SSC rates in the ciNPT-MLA group vs SOC. The reasons for these observed differences were not evaluated as part of this study. Future controlled clinical studies comparing outcomes between different ciNPT systems over closed orthopedic incisions would help to validate these study results., Competing Interests: The authors have declared financial relationships, which are detailed in the next section., (Copyright © 2023, Cooper et al.)

Background: Revision total knee arthroplasty (rTKA) is associated with significant risk of wound-related morbidity. The present study aimed to evaluate the 1) efficacy of closed-incision negative-pressure therapy (ciNPT) vs silver-impregnated antimicrobial dressing (AMD) in mitigating postoperative surgical site complications (SSCs), 2) the effect of ciNPT vs AMD on certain postoperative health utilization parameters, and on 3) patient-reported outcomes (PROs) improvement at 90-day postoperative follow-up.Methods: This multicenter randomized controlled trial was conducted between December 2017 and August 2019. Patients ≥22 years, at high risk for SSC, and receiving rTKA with full exchange and reimplantation of new prosthetic components or open reduction and internal fixation of periprosthetic fractures were screened for inclusion. Eligible patients were randomized to receive a commercially available ciNPT system or a silver-impregnated AMD (n = 147, each) for minimum of 5-day duration. Primary outcome was the 90-day incidence of SSCs with stratification in accordance with revision type (aseptic/septic). Secondary outcomes were the 90-day health care utilization parameters (readmission, reoperation, dressing changes, and visits) and PROs.Results: Of 294 patients randomized (age: 64.9 ± 9.0 years, female: 59.6%), 242 (82.0%) patients completed the study (ciNPT: n = 124; AMD: n = 118). The incidence of 90-day SSCs was lower for the ciNPT cohort (ciNPT: 3.4% vs AMD: 14.3%; odds ratio (OR): 0.22, 95% confidence interval (0.08, 0.59); P = .0013). Readmission rates (3.4% vs 10.2%, OR: 0.30(0.11, 0.86); P = .0208) and mean dressing changes (1.1 ± 0.3 vs 1.3 ± 1.0; P = .0003) were lower with ciNPT. The differences in reoperation rates, number of visits, and PRO improvement between both arms were not statistically significant (P > .05).Conclusion: ciNPT is effective in reducing the 90-day postoperative SSCs, readmission, and number of dressing changes after rTKA. Recommending routine implementation would require true-cost analyses. [ABSTRACT FROM AUTHOR]
