RESUMO
Background: In total joint replacement procedures, surgeons have increasingly adopted advanced multi-layer, watertight closure. The objective of the study was to compare the clinical and economic outcomes for advanced multi-layer, watertight closure patients to those with conventional closure with sutures and skin staples. Methods: Patients aged ≥18 years were included in the study if they underwent total joint arthroplasty of the hip or knee as an elective, primary, inpatient procedure between January 2014 and March 2019. Cohorts having advanced multi-layer, watertight closure or conventional closure were compared using multivariable regression analysis of surgical site infections, length of stay, operating room time, procedure time, discharge status, readmissions, reoperations, and hospital emergency department visits. Results: A total of 1828 patients received at least one total hip or knee replacement, of which 434 (23.7%) had advanced multi-layer, watertight closure and 1394 (76.3%) had conventional closure. Unadjusted time to readmission, when occurring, was considerably longer following advanced multi-layer, watertight closure (89.9 vs 51.1 days, p < 0.0001), and a lower proportion of the advanced multi-layer, watertight closure cohort required reoperation within 90 days (0.0% vs 2.6%, p < 0.0001). Adjusted mean hospital length of stay was approximately half of a day shorter for advanced multi-layer, watertight closure patients (1.10 vs 1.65 days; p < 0.001), and they were also more likely to be discharged to home (Odds Ratio: 4.61; p = 0.002). Conclusion: Among patients undergoing total hip and knee arthroplasty in a highly optimized real-world clinical practice, advanced multi-layer, watertight closure was associated with significantly shorter inpatient length of stay and increased likelihood of being discharged to home compared with conventional closure. These findings suggest that advanced multi-layer, watertight closure is a valuable component of an optimal workflow for total hip or knee replacement, and may be especially valuable for high-risk patients.
RESUMO
BACKGROUND: Spinal fusion surgery (SFS) is one of the most common operations in the United States, >450,000 SFSs are performed annually, incurring annual costs >$10 billion. OBJECTIVES: We used a nationwide longitudinal database to accurately assess incidence and payments associated with management of postoperative infection following SFS. METHODS: We conducted a retrospective, observational cohort analysis of 210,019 patients undergoing SFS from 2014 to 2018 using IBM MarketScan commercial and Medicaid-Medicare databases. We assessed rates of superficial/deep incisional SSIs, from 3 to 180 days after surgery using Cox proportional hazard regression models. To evaluate adjusted payments for patients with/without SSIs, adjusted for inflation to 2019 Consumer Price Index, we used generalized linear regression models with log-link and γ distribution. RESULTS: Overall, 6.6% of patients experienced an SSI, 1.7% superficial SSIs and 4.9% deep-incisional SSIs, with a median of 44 days to presentation for superficial SSIs and 28 days for deep-incisional SSIs. Selective risk factors included surgical approach, admission type, payer, and higher comorbidity score. Postoperative incremental commercial payments for patients with superficial SSI were $20,800 at 6 months, $26,937 at 12 months, and $32,821 at 24 months; incremental payments for patients with deep-incisional SSI were $59,766 at 6 months, $74,875 at 12 months, and $93,741 at 24 months. Corresponding incremental Medicare payments for patients with superficial incisional at 6, 12, 24-months were $11,044, $17,967, and $24,096; while payments for patients with deep-infection were: $48,662, $53,757, and $73,803 at 6, 12, 24-months. CONCLUSIONS: We identified a 4.9% rate of deep infection following SFS, with substantial payer burden. The findings suggest that the implementation of robust evidence-based surgical-care bundles to mitigate postoperative SFS infection is warranted.

BACKGROUND: To compare clinical and economic outcomes after sternotomy for cardiac surgery with skin closure through 2-octyl cyanoacrylate plus polymer mesh tape (2OPMT) versus conventional absorbable sutures plus waterproof wound dressings (CSWWD). METHODS: Retrospective study using the Premier Healthcare Database. Patients undergoing a cardiac surgery requiring sternotomy with 2OPMT or CSWWD were included. Primary outcome was 60-day cumulative incidence of diagnosis for wound complications (infection, dehiscence). Secondary outcomes were index admission hospital length of stay (LOS), total hospital-borne costs, discharge status, and 60-day cumulative incidences of inpatient readmission and reoperation. After propensity score matching, outcomes were compared between the 2OPMT and CSWWD groups using bivariate multilevel mixed-effects generalized linear models. RESULTS: Overall, 7,901 2OPMT patients and 10,775 CSWWD patients were eligible for study. After propensity score matching on 68 variables, each group comprised 5,338 patients (total study N = 10,676). The 2OPMT and CSWWD groups did not differ significantly in terms of the 60-day cumulative incidences of wound complication (3.47% vs 3.47%, p = 0.996), inpatient readmission (12.6% vs. 13.6%, p = 0.354), and reoperation (10.3% vs 10.1%, p = 0.808), as well as discharge to home versus non-home setting (77.2% vs. 75.1%), p = 0.254. However, the 2OPMT group had significantly lower LOS (9.2 days vs 10.6 days, p < 0.001) and total hospital-borne costs ($50,174 vs $60,526, p < 0.001). CONCLUSIONS: This large observational study provides evidence that sternotomy skin closure with 2OPMT is associated with nearly identical 60-day cumulative incidence of wound complication as compared with CSWWD, while exhibiting a significant association with lower LOS and total hospital-borne costs. Trial registration Not applicable.

PURPOSE: Open colorectal surgery is associated with a high rate of postoperative wound complications. This is a single-arm study of real-world outcomes of triclosan-coated barbed suture (Ethicon's STRATAFIXTM Symmetric PDSTM Plus Knotless Tissue Control Device [SSPP]) used in open colorectal surgery. METHODS: Retrospective cohort study using the Premier Healthcare Database. The study included patients who underwent an inpatient open colorectal surgery with wound closure using SSPP (size 0 or 1 to increase the likelihood the suture was used in fascia) between October 2015-September 2019 (N=593). Wound complications, hospital length of stay, total hospital costs (2019 US$), and all-cause readmissions post-discharge were measured. Post-hoc multivariable analyses compared wound complications between non-elective admissions and elective. RESULTS: The overall incidence of wound complications within 30-days post-procedure was 7.1%, with the majority of those being surgical site infections (SSI) (6.0%). Mean operation time was 190 (standard deviation [SD]=64.4) mins, postoperative length of stay was 8.1 (SD=11.9) days, 30-day readmission rate was 11.8%, and total hospital costs were $31,693 (SD=$40,076). As compared with published literature on the rate of SSI in colorectal surgery, the 30-day rate of SSI in the present study (6.0%) fell within the range of 5.4% to 18.2% for open colorectal surgery and from 4.3% to 21.5% for combined open and minimally invasive procedures. Multivariable-adjusted incidence proportions of wound complications were slightly lower for non-elective admissions and did not differ significantly from those of elective admissions. CONCLUSION: The rate of wound complications observed in the present study falls within the range of rates previously reported in the literature, suggesting a safe and effective role for SSPP in open colorectal surgery. In post hoc analyses, the adjusted rate of wound complications was similar between non-elective and elective admissions. Head-to-head studies are required to determine comparative advantages or disadvantages for SSPP versus other sutures.
RESUMO
OBJECTIVE: To compare economic and clinical outcomes of barbed sutures versus conventional sutures alone in wound closure for patients undergoing spinal surgery. METHOD: A retrospective study using the Premier Healthcare Database. The database was searched for patients who underwent elective inpatient spinal surgery (fusion or laminectomy) for a spinal disorder between 1 January 2014 and 30 June 2018 (first=index admission). Using billing records for medical supplies used during the index admission, patients were classified into mutually-exclusive groups: patients with any use of STRATAFIX (Ethicon, US) knotless tissue control devices (barbed sutures group); or patients with use of conventional sutures alone (conventional sutures group). Outcomes included the index admission's length of stay, total and subcategories of hospital costs, non-home discharge, operating room time (ORT, minutes), wound complications and readmissions within ≤90 days. Propensity score matching and generalised estimating equations were used to compare outcomes between the study groups. RESULTS: After matching, 3705 patients were allocated to each group (mean age=61.5 years [standard deviation, SD±12.9]; 54% were females). Compared with the conventional suture group, the barbed suture group had significantly lower mean ORT (239±117 minutes, versus 263±79 minutes conventional sutures, p=0.015). Operating room costs were also siginificantly lower in the barbed suture group ($6673±$3976 versus $7100±$2700 conventional sutures, p=0.020). Differences were statistically insignificant for other outcomes (all p>0.05). Subanalysis of patients undergoing fusions of ≥2 vertebral joints yielded consistent results. CONCLUSION: In this study, wound closure incorporating barbed sutures was associated with lower ORT and operating room costs, with no significant difference in wound complications or readmissions, when compared with conventional sutures alone.

BACKGROUND: The incidence of surgical site infection (SSI) across surgical procedures, specialties, and conditions is reported to vary from 0.1% to 50%. Operative duration is often cited as an independent and potentially modifiable risk factor for SSI. The objective of this systematic review was to provide an in-depth understanding of the relation between operating time and SSI. PATIENTS AND METHODS: This review included 81 prospective and retrospective studies. Along with study design, likelihood of SSI, mean operative times, time thresholds, effect measures, confidence intervals, and p values were extracted. Three meta-analyses were conducted, whereby odds ratios were pooled by hourly operative time thresholds, increments of increasing operative time, and surgical specialty. RESULTS: Pooled analyses demonstrated that the association between extended operative time and SSI typically remained statistically significant, with close to twice the likelihood of SSI observed across various time thresholds. The likelihood of SSI increased with increasing time increments; for example, a 13%, 17%, and 37% increased likelihood for every 15 min, 30 min, and 60 min of surgery, respectively. On average, across various procedures, the mean operative time was approximately 30 min longer in patients with SSIs compared with those patients without. CONCLUSIONS: Prolonged operative time can increase the risk of SSI. Given the importance of SSIs on patient outcomes and health care economics, hospitals should focus efforts to reduce operative time.

OBJECTIVES: To determine hospital resource utilization, associated costs and the risk of complications during hospitalization for four types of surgical resections and to estimate the incremental burden among patients with cancer compared to those without cancer. METHODS: Patients (≥18 years old) were identified from the Premier Research Database of US hospitals if they had any of the following types of elective surgical resections between 1/2008 and 12/2014: lung lobectomy, lower anterior resection of the rectum (LAR), liver wedge resection, or total hysterectomy. Cancer status was determined based on ICD-9-CM diagnosis codes. Operating room time (ORT), length of stay (LOS), and total hospital costs, as well as frequency of bleeding and infections during hospitalization were evaluated. The impact of cancer status on outcomes (from a hospital perspective) was evaluated using multivariable generalized estimating equation models; analyses were conducted separately for each resection type. RESULTS: Among the identified patients who underwent surgical resection, 23 858 (87.9% with cancer) underwent lung lobectomy, 13 522 (63.8% with cancer) underwent LAR, 2916 (30.0% with cancer) underwent liver wedge resection and 225 075 (11.3% with cancer) underwent total hysterectomy. After adjusting for patient, procedural, and hospital characteristics, mean ORT, LOS, and hospital cost were statistically higher by 3.2%, 8.2%, and 9.2%, respectively for patients with cancer vs. no cancer who underwent lung lobectomy; statistically higher by 6.9%, 9.4%, and 9.6%, respectively for patients with cancer vs. no cancer who underwent LAR; statistically higher by 4.9%, 14.8%, and 15.7%, respectively for patients with cancer vs. no cancer who underwent liver wedge resection; and statistically higher by 16.0%, 27.4%, and 31.3%, respectively for patients with cancer vs. no cancer who underwent total hysterectomy. Among patients who underwent each type of resection, risks for bleeding and infection were generally higher among patients with cancer as compared to those without cancer. CONCLUSIONS: In this analysis, we found that patients who underwent lung lobectomy, lower anterior resection of the rectum (LAR), liver wedge resection or total hysterectomy for a cancer indication have significantly increased hospital resource utilization compared to these same surgeries for benign indications.
