Cluster-randomized crossover trial of chlorhexidine-alcohol versus iodine-alcohol for prevention of surgical-site infection (SKINFECT trial).

Background: Surgical-site infection (SSI) is a serious surgical complication that can be prevented by preoperative skin disinfection. In Western European countries, preoperative disinfection is commonly performed with either chlorhexidine or iodine in an alcohol-based solution. This study aimed to investigate whether there is superiority of chlorhexidine-alcohol over iodine-alcohol for preventing SSI. Methods: This prospective cluster-randomized crossover trial was conducted in five teaching hospitals. All patients who underwent breast, vascular, colorectal, gallbladder or orthopaedic surgery between July 2013 and June 2015 were included. SSI data were reported routinely to the Dutch National Nosocomial Surveillance Network (PREZIES). Participating hospitals were assigned randomly to perform preoperative skin disinfection using either chlorhexidine-alcohol (0·5 per cent/70 per cent) or iodine-alcohol (1 per cent/70 per cent) for the first 3 months of the study; every 3 months thereafter, they switched to using the other antiseptic agent, for a total of 2 years. The primary endpoint was the development of SSI. Results: A total of 3665 patients were included; 1835 and 1830 of these patients received preoperative skin disinfection with chlorhexidine-alcohol or iodine-alcohol respectively. The overall incidence of SSI was 3·8 per cent among patients in the chlorhexidine-alcohol group and 4·0 per cent among those in the iodine-alcohol group (odds ratio 0·96, 95 per cent c.i. 0·69 to 1·35). Conclusion: Preoperative skin disinfection with chlorhexidine-alcohol is similar to that for iodine-alcohol with respect to reducing the risk of developing an SSI.

Antecedentes: La infección del sitio quirúrgico (surgical site infection, SSI) es una complicación quirúrgica grave que se puede prevenir mediante una desinfección cutánea preoperatoria. En los países de Europa occidental, la desinfección preoperatoria se realiza habitualmente usando clorhexidina o yodo en una solución a base de alcohol. Nuestro objetivo fue investigar si la clorhexidina alcohólica es superior al yodo con alcohol para prevenir la SSI. Métodos: Este ensayo prospectivo aleatorizado por conglomerados y de grupos cruzados se realizó en cinco hospitales docentes. Se incluyeron todos los pacientes que se sometieron a cirugía mamaria, vascular, colorrectal, biliar y ortopédica entre julio de 2013 y junio de 2015. Los datos de SSI se presentaron de manera rutinaria a la Red Nacional Holandesa de Vigilancia Nosocomial (PREZIES). Los hospitales participantes fueron asignados al azar para realizar una desinfección cutánea preoperatoria con clorhexidina alcohólica (0,5%/70%) o yodo con alcohol (1%/70%) durante los primeros tres meses del estudio; cada 3 meses a partir de entonces, cambiaron a usar el otro agente antiséptico, durante un total de 2 años. El criterio de valoración principal fue el desarrollo de SSI. Resultados: Se incluyeron un total de 3.665 pacientes; 1.835 y 1.830 de estos pacientes recibieron desinfección cutánea preoperatoria con clorhexidina alcohólica o yodo con alcohol, respectivamente. La incidencia global de SSI fue del 3,8% entre los pacientes en el grupo de clorhexidina alcohólica y del 4,0% entre los pacientes en el grupo de yodo con alcohol (razón de oportunidades, odds ratio, OR 0,96; i.c. del 95%: 0,69­1,35). Conclusión: La desinfección cutánea preoperatoria con clorhexidina alcohólica es similar al yodo con alcohol con respecto a la reducción del riesgo de desarrollar una SSI.

Hospital costs of complications after esophagectomy for cancer.

OBJECTIVE: The purpose of this study was to estimate the economic burden of postoperative complications after esophagectomy for cancer, in order to optimally allocate resources for quality improvement initiatives in the future. METHODS: A retrospective analysis of prospectively collected clinical and financial outcomes after esophageal cancer surgery in a tertiary referral center in the Netherlands was performed. Data was extracted from consecutive patients registered in the Dutch Upper GI Cancer Audit between 2011 and 2014 (n = 201). Costs were measured up to 90-days after hospital discharge and based on Time-Driven Activity-Based Costing. The additional costs were estimated using multiple linear regression models. RESULTS: The average total cost for one patient after esophagectomy was €37,581 (±31,372). The estimated costs of an esophagectomy without complications were €23,476 (±6496). Mean costs after minor (47%) and severe complications (29%) were €31,529 (±23,359) and €59,167 (±42,615) (p < 0.001), respectively. The 5% most expensive patients were responsible for 20.3% of the total hospital costs assessed in this study. Patient characteristics associated with additional costs in multivariable analysis included, age >70 (+€2,922, p = 0.036), female gender (+€4,357, p = 0.005), COPD (+€5,415, p = 0.002), and a history of thromboembolic events (+€6,213, p = 0.028). Complications associated with a significant increase in costs in multivariable analysis included anastomotic leakage (+€4,123, p = 0.008), cardiac complications (+€5,711, p = 0.003), chyle leakage (+€6,188, p < 0.001) and postoperative bleeding (+€31,567, p < 0.001). CONCLUSIONS: Complications and severity of complications after esophageal surgery are associated with a substantial increase in costs. Although not all postoperative complications can be prevented, implementation of preventive measures to reduce complications could result in a considerable cost reduction and quality improvement.

[Necrotising soft tissue infection of orbital area and hand: an unusual combination]. / Necrotiserende wekedeleninfectie van hand en oog.

BACKGROUND: Necrotising soft tissue infection (NSTI) is an infection of the subcutaneous tissues and often follows a fulminant course if not recognised in time. CASE DESCRIPTION: A 78-year-old man was brought to our emergency department in septic shock. Physical examination revealed an erythematous and painful swelling of the right eyelids and to a lesser extent of the right hand. The infection progressed at both sites, and suspicion of NSTI arose. An emergency surgical debridement was performed. Pathological examination of the excised tissue confirmed the presence of a necrotising infection of the fascia consistent with NSTI at both sites. CONCLUSION: This case history describes a, not previously described, 'double' presentation of NSTI. In a patient with misunderstood sepsis in combination with a soft tissue infection, it is important to consult a surgeon immediately. This case report emphasises the need for a multidisciplinary approach when treating patients with these clinical pictures. CONFLICT OF INTEREST AND FINANCIAL SUPPORT: NONE DECLARED.

Costs of complications after colorectal cancer surgery in the Netherlands: Building the business case for hospitals.

BACKGROUND: Healthcare providers worldwide are struggling with rising costs while hospitals budgets are under stress. Colorectal cancer surgery is commonly performed, however it is associated with a disproportionate share of adverse events in general surgery. Since adverse events are associated with extra hospital costs it seems important to explicitly discuss the costs of complications and the risk factors for high-costs after colorectal surgery. METHODS: Retrospective analysis of clinical and financial outcomes after colorectal cancer surgery in 29 Dutch hospitals (6768 patients). Detailed clinical data was derived from the 2011-2012 population-based Dutch Surgical Colorectal Audit database. Costs were measured uniform in all participating hospitals and based on Time-Driven Activity-Based Costing. FINDINGS: Of total hospital costs in this study, 31% was spent on complications and the top 5% most expensive patients were accountable for 23% of hospitals budgets. Minor and severe complications were respectively associated with a 26% and 196% increase in costs as compared to patients without complications. Independent from other risk factors, ASA IV, double tumor, ASA III, short course preoperative radiotherapy and TNM-4 stadium disease were the top-5 attributors to high costs. CONCLUSIONS: This article shows that complications after colorectal cancer surgery are associated with a substantial increase in costs. Although not all surgical complications can be prevented, reducing complications will result in considerable cost savings. By providing a business case we show that investments made to develop targeted quality improvement programs will pay off eventually. Results based on this study should encourage healthcare providers to endorse quality improvement efforts.
