Infection prevention and surgery in the pandemic era

The COVID-19 pandemic has had a significant impact on surgical specialties. COVID-19 carries a significant risk to the surgical patient and the healthcare workers looking after them, with an increased incidence of pulmonary complications and mortality in patients who test positive perioperatively. Appropriate infection prevention and control measures are critical to ensure appropriate care is given and to reduce the risk of onward transmission. This article will discuss the measures that have been instigated and contributed to infection control in surgery, such as testing, patient isolation, personal protective equipment and ventilation. The COVID-19 pandemic has led to healthcare workers across many specialities working together to provide essential clinical care. This collaborative approach is critical to maintain excellent infection prevention and control practices required during this pandemic, which protect patients and preserve surgical services.     

The implementation of an infection control bundle within a Total Care Burns Unit

AimTo evaluate the impact of the implementation of a best practice infection prevention and control bundle on healthcare associated burn wound infections in a paediatric burns unit.BackgroundBurn patients are vulnerable to infection. For this patient population, infection is associated with increased morbidity and mortality, thereby representing a significant challenge for burns clinicians who care for them.MethodsAn interrupted time series was used to compare healthcare associated burn wound infections in paediatric burn patients before and after implementation of an infection prevention and control bundle. Prospective surveillance of healthcare associated burn wound infections was conducted from 2012 to 2014. Other potential healthcare associated infection rates were also reviewed over the study period, including urinary tract infections, pneumonia, upper respiratory tract infections and sepsis. An infection prevention and control bundle developed in collaboration between the paediatric burn unit and infection control clinicians was implemented in 2013 in addition to previous standard practice.ResultsDuring the study period a total of 626 patients were admitted to the paediatric burns unit. Healthcare associated burn wound infections reduced from 34 in 2012 to 0 in 2014 following the implementation of the infection prevention and control bundle. Pneumonia and sepsis also reduced to 0 in 2013 and 2014, however one upper respiratory tract infection occurred in 2013 and urinary tract infections persisted in 2013.ConclusionThe implementation of an infection prevention and control bundle was effective in reducing healthcare associated burn wound infections, pneumonia and sepsis within our paediatric burns unit. Urinary tract infections remain a challenge for future improvement.     

Steroids to reduce the impact on delirium (STRIDE): a double-blind,randomised, placebo-controlled feasibility trial of pre-operative dexamethasone in people with hip fracture

Neuro-inflammation may be important in the pathogenesis of postoperative delirium following hip fracture surgery. Studies have suggested a potential role for steroids in reducing postoperative delirium; however, the potential efficacy and safety of pre-operative high-dose dexamethasone in this specific population is largely unknown. Conducting such a study could be challenging, considering the multidisciplinary team involvement and the emergency nature of the surgery. The aim of this study was to assess feasibility and effectiveness of dexamethasone given as early as possible following hospital admission for hip fracture, to inform whether a full-scale trial is warranted. This single-centre, randomised, double-blind, placebo-controlled study randomly allocated 79 participants undergoing hip fracture surgery to dexamethasone 20 mg or placebo pre-operatively. Eligibility and recruitment rates, timing of the intervention and adverse events were recorded. Incidence and severity of postoperative delirium were assessed using the 4AT delirium screening tool and the Memorial Delirium Assessment Scale. Postoperative pain, length of stay and mortality were also assessed. The eligibility rate for inclusion was 178/527 (34%), and 57/178 (32%) of eligible patients presented to hospital when no researcher was available (e.g. after-hours, weekends, public holidays). Recruitment was limited mainly by ethical limitations (not including patients with impaired cognition) and lack of weekend staffing. Median (IQR [range]) time from emergency department admission to drug administration was 13.3 (5.9–17.6 [1.8–139.6]) hours. There was a significant difference in delirium severity scores, favouring the dexamethasone group: median (IQR [range]) 5 (3–6 [3–7]) vs. 9 (6–13 [5–14]) in the placebo group, with the probability of superiority effect size being 0.89, p = 0.010. Delirium incidence did not differ between groups: 6/40 (15%) in the dexamethasone group vs. 9/39 (23%) in the placebo group, relative risk (95%CI) 0.65 (0.22–1.65), p = 0.360). A larger randomised controlled trial is feasible and ideally this should include people with existing cognitive impairment, seven days-a-week cover and a multicentre design.     

Resumen ejecutivo del Documento de Consenso de la Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica (SEIMC) y de la Asociación Española de Cirujanos (AEC) en profilaxis antibiótica en cirugía

Antibiotic prophylaxis in surgery is one of the most effective measures for preventing surgical site infection, although its use is frequently inadequate and may even increase the risk of infection, toxicities and antimicrobial resistance. As a result of advances in surgical techniques and the emergence of multidrug-resistant organisms, the current guidelines for prophylaxis need to be revised.The Sociedad Española de Enfermedades Infecciosas (Spanish Society of Infectious Diseases and Clinical Microbiology) (SEIMC) together with the Asociación Española de Cirujanos (Spanish Association of Surgeons) (AEC) have revised and updated the recommendations for antibiotic prophylaxis in surgery to adapt them to any type of surgical intervention and to current epidemiology. This document gathers together the recommendations on antimicrobial prophylaxis in the various procedures, with doses, duration, prophylaxis in special patient groups, and in epidemiological settings of multidrug resistance to facilitate standardized management and the safe, effective and rational use of antibiotics in elective surgery.     

从化地区7~9岁儿童第一恒磨牙窝沟封闭效果研究

目的分析从化地区7~9岁儿童第一恒磨牙窝沟封闭效果及其影响因素。方法选取2019年1月至2020年12月在南方医科大学第五附属医院接受第一恒磨牙窝沟封闭的7~9岁儿童为研究对象,在封闭完成后6、12个月进行第一恒磨牙窝沟封闭效果的评估,采用单因素、多因素分析封闭剂脱落的影响因素。结果从化地区7~9岁儿童完成第一恒磨牙窝沟封闭人数873例(窝沟封闭牙齿数3012颗),6个月、12个月复查发现脱落率分别为10.13%、11.95%。年龄、软垢指数(DI)、刷牙频率、饮食甜品及碳酸饮料频率、龋面数不同与从化地区7~9岁儿童窝沟封闭剂脱落率有关(P<0.05或P<0.01)。多因素Logistic回归分析结果显示,DI越大、饮食甜品及碳酸饮料频率≥2次/d、龋面数越多的7~9岁儿童窝沟封闭后6个月或12个月发生脱落风险较高,而年龄越大、刷牙频率≥2次/d的7~9岁儿童窝沟封闭后6个月或12个月发生脱落风险较低(P<0.05或P<0.01)。结论从化7~9岁儿童第一恒磨牙窝沟封闭效果与年龄、口腔卫生情况、饮食习惯、龋面数、刷牙频率有关,应建立良好的刷牙习惯及饮食习惯,从而降低窝沟封闭剂脱落风险。

Timebanking and the co-production of preventive social care with adults; what can we learn from the challenges of implementing person-to-person timebanks in England?

This paper explores the potential contribution of timebanking, an innovative volunteering scheme, to the co-production of preventive social care with adults in England. Interest in volunteering in social care has increased as one proposed solution to the international crisis of a rising demand for services in juxtaposition with decreased resources. Volunteering has been particularly promoted in preventive services that prevent or delay care needs arising. Despite sustained interest in volunteering and co-production in social care, little is known about how theory translates into practice. Reporting implementation data from a Realistic Evaluation of six case studies in England, this paper explores one volunteering scheme, timebanking. The research explores how timebanks were working, what contribution they can make to adult social care, and whether they are an example of co-production. Data collected included interviews, focus groups or open question responses on surveys from 84 timebank members, and semi-structured interviews with 13 timebank staff. Each timebank was visited at least twice, and all timebank activity was analysed for a period of 12 months. Data were triangulated to improve reliability. The research found that in practice, timebanks were not working as described in theory, there were small numbers of person-to-person exchanges and some timebanks had abandoned this exchange model. Timebanks faced significant implementation challenges including managing risk and safeguarding and the associated bureaucracy, a paternalistic professional culture and the complexity of the timebank mechanism which required adequate resources. Lessons for timebanks are identified, as well as transferable lessons about co-production and volunteering in social care if such schemes are to be successful in the future.
