A perioperative multidisciplinary care bundle reduces surgical site infections in patients undergoing synchronous colorectal and liver resection

Surgical Site Infections in Simultaneous Colorectal and Liver Resections for Metastatic Colorectal Adenocarcinoma

BACKGROUND

Surgical site infections (SSIs) are a major driver of morbidity after combined liver and colorectal surgery for metastatic colorectal cancer. Available literature is inadequate to characterize risk factors and benchmarks for quality improvement.

METHODS

Consecutive cases of simultaneous liver and colorectal surgery for colorectal adenocarcinoma from November 2013 through September 2022 were reviewed for SSIs per National Surgical Quality Improvement Program (NSQIP) and National Healthcare Safety Network (NHSN) criteria. Univariable and multivariable logistic regression evaluated associations with NSQIP 30-day organ-space SSIs.

RESULTS

In 580 procedures, the rate of 30-day organ-space SSIs was 16% (n = 94) using NSQIP criteria and 11% (n = 64) using NHSN criteria; 4% (n = 24) had incisional SSIs by both criteria. Most organ-space SSIs were perihepatic, and a minority were associated with bile (26%) or anastomotic (15%) leak. Independent risk factors for organ-space SSIs included major liver resection, upper abdominal (compared with lower abdominal/pelvic) colorectal procedure, and ostomy reversal. Organ-space SSI rates increased over time by approximately 16% per calendar year (p = 0.02) despite a declining rate of major liver resection; incisional SSI rates remained low. Overall, major morbidity was 22%, with 7-day median length of stay (interquartile range 6-9) and 0.3% 90-day mortality.

CONCLUSION

Organ-space SSIs are a significant driver of postoperative morbidity in simultaneous liver and colorectal resections for metastatic colorectal adenocarcinoma. Our findings confirm simultaneous resection remains safe and interventions to mitigate the risk of perihepatic organ-space SSIs in high-risk patients are warranted.

Comparison of Robotic, Laparoscopic, and Open Resections of Nonmetastatic Colon Cancer

BACKGROUND

Laparoscopic resection for colon cancer has not been associated with improvements in oncological outcomes in comparison to open resection. Robotic resections are associated with increased lymph node yield and radicality of mesenteric resection in patients with right-sided tumors. It is unclear whether lymph node yield is higher in robotic resections in other parts of the colon and whether higher lymph node yield is associated with improved survival.

OBJECTIVE

To compare survival rates between robotic, laparoscopic, and open resections in a large cohort of patients with nonmetastatic colon cancer.

DESIGN

This is a retrospective observational study.

SETTING

A single comprehensive cancer center.

PATIENTS

Patients who underwent resection of nonmetastatic primary colon cancer between January 2006 and December 2018.

MAIN OUTCOME MEASURES

Univariable and multivariable models were used to identify predictors of disease-free and overall survival. Lymph node yield and perioperative outcomes were compared between operative approaches.

RESULTS

There were 2398 patients who met the inclusion criteria: 699 (29%) underwent open, 824 (34%) underwent laparoscopic, and 875 (36%) underwent robotic resection. The median follow-up was 3.8 years (45.4 months). Robotic surgery was associated with higher lymph node yield and radicality of mesenteric resection. On multivariable analysis, the surgical approach was not associated with a difference in disease-free or overall survival. Minimally invasive colectomy was associated with fewer complications and shorter length of stay in comparison to open surgery. In a direct comparison between the 2 minimally invasive approaches, robotic colectomy was associated with fewer complications, shorter length of stay, and lower conversion rate than laparoscopy.

LIMITATIONS

This was a single-center retrospective study.

CONCLUSIONS

Our data indicate that the 3 surgical approaches are similarly effective in treating primary resectable colon cancer and that differences in outcomes are observed primarily in the early postoperative period. See Video Abstract at http://links.lww.com/DCR/C115 .

COMPARACIN DE RESECCIONES ROBTICAS, LAPAROSCPICAS Y ABIERTAS DE CNCER DE COLON NO METASTSICO

ANTECEDENTES:La resección laparoscópica para el cáncer de colon no se ha asociado con mejoras en los resultados oncológicos en comparación con la resección abierta. Las resecciones robóticas se asocian con un mayor rendimiento de los ganglios linfáticos y la radicalidad de la resección mesentérica en pacientes con tumores del lado derecho. No está claro si la cosecha ganglionar es mayor en las resecciones robóticas en otras partes del colon y si un mayor rendimiento de los ganglios linfáticos se asocia con una mejor supervivencia.OBJETIVO:Comparar las tasas de supervivencia entre resecciones robóticas, laparoscópicas y abiertas en una gran cohorte de pacientes con cáncer de colon no metastásico.DISEÑO:Este es un estudio observacional retrospectivo.ESCENARIO:Este estudio se realizó en un único centro oncológico integral.PACIENTES:Pacientes que se sometieron a resección de cáncer de colon primario no metastásico entre enero de 2006 y diciembre de 2018.PRINCIPALES MEDIDAS DE RESULTADO:Se utilizaron modelos univariables y multivariables para identificar predictores de supervivencia libre de enfermedad y global. La cosecha ganglionar y los resultados perioperatorios se compararon entre los abordajes quirúrgicos.RESULTADOS:Hubo 2398 pacientes que cumplieron con los criterios de inclusión: 699 (29%) se sometieron a cirugía abierta, 824 (34%) se sometieron a resección laparoscópica y 875 (36%) se sometieron a resección robótica. La mediana de seguimiento fue de 3,8 años (45,4 meses). La cirugía robótica se asoció con una mayor cosecha ganglionar y la radicalidad de la resección mesentérica. En el análisis multivariable, el abordaje quirúrgico no se asoció con una diferencia en la supervivencia general o libre de enfermedad. La colectomía mínimamente invasiva se asoció con menos complicaciones y una estancia más corta en comparación con la cirugía abierta. En una comparación directa entre los dos enfoques mínimamente invasivos, la colectomía robótica se asoció con menos complicaciones, una estancia más corta y una tasa de conversión más baja que la laparoscopia.LIMITACIONES:Este fue un estudio retrospectivo de un solo centro.CONCLUSIONES:Nuestros datos indican que los tres enfoques quirúrgicos son igualmente efectivos en el tratamiento del cáncer de colon resecable primario y que las diferencias en los resultados se observan principalmente en el período posoperatorio temprano.

Reducing Surgical Site Infection by Prophylactic Negative Pressure Wound Therapy in a Cohort of General Surgery Patients

Background

Surgical site infection (SSI) is one of the leading complications in health care. Negative pressure wound therapy (NPWT) is meanwhile widely prophylactically used for preventing SSIs. For evaluating the results of the implantation of this technique, we used the Simon single-arm study design and examine whether NPWT has a prophylactic effect on reducing SSIs in a cohort of general surgery patients.

Methods

This single-arm, two-stage study includes 81 elective general surgery patients and corresponds to the Simon's design. The sample size calculation was based on a reduction in the superficial SSI rate from 12 to 4% (power 80%, significance level 5%) using a NPWT system. In compliance with Simon's two-Stage design, the study required the recruitment of 34 patients in stage I and 47 patients in stage II. The two-stage design method would be discarded in case of a wound infection in 3 or more patients in stage I or 6 or more patients in stage II. Using the NPWT system in the operating room, a negative pressure wound dressing was applied post-operatively and removed after 7 days. According to the criteria of the Centres for Disease Control and Prevention (CDC), post-operative wound documentation followed on day 7 and 30.

Results

In stage I, no SSI was apparent. In stage II, 3 patients had SSIs (CDC grade I).

Conclusion

A prophylactic NPWT can significantly reduce the wound infection rate in elective general surgery.

The Impact of Care Bundles on the Incidence of Surgical Site Infections: A Systematic Review

OBJECTIVE

This systematic review assesses the effects of care bundles on the incidence of surgical site infections (SSIs).

DATA SOURCES

The search was conducted between February and May 2021, using PubMed, CINAHL, SCOPUS, Cochrane, and EMBASE databases.

STUDY SELECTION

Studies were included if they used systematic review methodology, were in English, used a quantitative design, and explored the use of care bundles for SSI prevention. A total of 35 studies met the inclusion criteria, and 26 provided data conducive to meta-analysis.

DATA EXTRACTION

Data were extracted using a predesigned extraction tool, and analysis was undertaken using RevMan (Cochrane, London, UK). Quality appraisal was undertaken using evidence-based librarianship.

DATA SYNTHESIS

The mean sample size was 7,982 (median, 840) participants. There was a statistically significant difference in SSI incidence in favor of using a care bundle (SSI incidence 4%, 703/17,549 in the care bundle group vs 7%, 1,157/17,162 in the usual care group). The odds ratio was 0.55 (95% confidence interval, 0.41-0.73; P < .00001), suggesting that there is a 45% reduction in the odds of SSI development for the care bundle group. The mean validity score for all studies was 84% (SD, 0.04%).

CONCLUSIONS

The results indicate that implementing care bundles reduced SSI incidence. However, because there was clinically important variation in the composition of and compliance with care bundles, additional research with standardized care bundles is needed to confirm this finding.

Prospective study of surgical site infections post-open esophageal cancer surgery, and the impact of care bundles

SSIs represent common infection-related morbidity following major surgery. Modern care bundles have been established as prophylactic measures aimed at preventing SSI occurring postoperatively. SSI incidence and data on common culprit pathogens post-esophagectomy for cancer have not been previously reported. Patients (2013-2018) treated with curative intent were studied. SSI was defined as per the Center for Disease Control (CDC) definition. A care bundle pathway following the National Institute for Clinical Excellence (NICE) guidelines for prevention of SSIs was introduced in 2013 and was audited quarterly. Risk factors and associations of SSIs were analyzed, as was the prevalence of isolated pathogens. Multivariable logistic regression examined independently predictive factors of SSIs and oncologic outcomes. Of 343 patients, 34 (9.9%) developed a postoperative SSI, with a median (range) of 8 (6-17). Quarterly audit carried out over 6 years showed no significant annual variance or trend. The most prevalent pathogen cultured was Methicillin-sensitive Staphylococcus aureus (MSSA) in nine patients (32%) followed by Candida albicans (29%), Escherichia coli (14%), and Enterococcus faecium (11%). SSI was significantly associated with pneumonia (P = 0.001), respiratory failure (P = 0.014), atrial fibrillation (P = 0.004), anastomotic leak (P < 0.001), and in-hospital blood transfusions (P = 0.031). SSI did not impact the overall survival (P = 0.951). SSI rates can be maintained at less than 10% using strict care bundles and regular audit. The most common culprit pathogen is gram-positive MSSA representing 32% of cases. These data are novel and may represent a modern benchmark for SSI post-open esophagectomy for cancer. This study highlights the incidence and associations of SSI post-esophageal cancer surgery.

The application of patient-centered care bundle significantly reduces incidence of perioperative respiratory complications in hip fracture patients aged 80 and over

This study was designed as a pilot test to analyze the effect of patient-centered care (PCC) bundle intervention on perioperative respiratory complications and other outcomes in hip fracture patients aged ≥80. Between Jan 2018 and Dec 2019, 198 patients comprised the routine care group and 187 comprised the PCC bundle group. After propensity score matching, 151 remained in each group. Incidence of perioperative respiratory complications in the PCC bundle group was significantly lower than in the routine care group (all P < 0.05). Furthermore, significant reductions were observed in surgery delay, length of stay, incidence of arrhythmia, hypoproteinemia, and electrolyte disturbance (all P < 0.05) in the PCC bundle group. Age-Adjusted Charlson Comorbidity Index score was related, but only weakly, to length of stay and the number of perioperative complications. These results suggested that the PCC bundle might be a more suitable care modality for patients ≥80 with hip fracture.

The Costs of Complications and Unplanned Readmissions after Pancreatoduodenectomy for Pancreatic and Periampullary Tumors: Results from a Single Academic Center

Simple Summary

Complications lead to unplanned readmissions (UR) and are reported to be associated with a two- to threefold increase in hospital admission costs. Since healthcare costs are increasing worldwide, cost containment is the major challenge for future healthcare. In the literature, there are only a few studies that analysed hospital costs after pancreatoduodenectomy (PD). In this study, we aimed to create an understanding of the costs of complications and UR in patients who underwent a PD.

Abstract

Background/Objectives: Complications after pancreatoduodenectomy (PD) lead to unplanned readmissions (UR), with a two- to threefold increase in admission costs. In this study, we aimed to create an understanding of the costs of complications and UR in this patient group. Furthermore, we aimed to generate a detailed cost overview that can be used to build a theoretical model to calculate the cost efficacy for prehabilitation. Methods: A retrospective cohort analysis was performed using the Dutch Pancreatic Cancer Audit (DPCA) database of patients who underwent a PD at our institute between 2013 and 2017. The total costs of the index hospital admission and UR related to the PD were collected. Results: Of the 160 patients; 35 patients (22%) had an uncomplicated course; 87 patients (54%) had minor complications, and 38 patients (24%) had severe complications. Median costs for an uncomplicated course were EUR 25.682, and for a complicated course, EUR 32.958 (p = 0.001). The median costs for minor complications were EUR 30.316, and for major complications, EUR 42.664 (p = 0.001). Costs were related to the Comprehensive Complication Index (CCI). The median costs of patients with one or more UR were EUR 41.199. Conclusions: Complications after PD led to a EUR 4.634–EUR 16.982 (18–66%) increase in hospital costs. A UR led to a cost increase of EUR 12.567 (44%). Since hospital costs are directly related to the CCI, reduction in complications will lead to cost-effectiveness.
