Cost-effectiveness of closed incision negative pressure wound therapy in preventing surgical site infection among obese women giving birth by caesarean section: An economic evaluation (DRESSING trial).

BACKGROUND: There is growing evidence regarding the potential of closed incision negative pressure wound therapy (ci-NPWT) to prevent surgical site infections (SSIs) in healing wounds by primary closure following a caesarean section (CS). AIM: To assess the cost-effectiveness of ci-NPWT compared to standard dressings for prevention of SSI in obese women giving birth by CS. MATERIALS AND METHODS: Cost-effectiveness and cost-utility analyses from a health service perspective were undertaken alongside a multicentre pragmatic randomised controlled trial, which recruited women with a pre-pregnancy body mass index ≥30 kg/m2 giving birth by elective/semi-urgent CS who received ci-NPWT (n = 1017) or standard dressings (n = 1018). Resource use and health-related quality of life (SF-12v2) collected during admission and for four weeks post-discharge were used to derive costs and quality-adjusted life years (QALYs). RESULTS: ci-NPWT was associated with AUD$162 (95%CI -$170 to $494) higher cost per person and an additional $12 849 (95%CI -$62 138 to $133 378) per SSI avoided. There was no detectable difference in QALYs between groups; however, there are high levels of uncertainty around both cost and QALY estimates. There is a 20% likelihood that ci-NPWT would be considered cost-effective at a willingness-to-pay threshold of $50 000 per QALY. Per protocol and complete case analyses gave similar results, suggesting that findings are robust to protocol deviators and adjustments for missing data. CONCLUSIONS: ci-NPWT for the prevention of SSI in obese women undergoing CS is unlikely to be cost-effective in terms of health service resources and is currently unjustified for routine use for this purpose.

Development and validation of a survey designed to measure patient experience of and preference for surgical wound care discharge education: A pilot study.

AIM OF THE STUDY: To develop and undertake validation testing of a survey designed to measure patients' experiences of and preferences for surgical wound care discharge education. MATERIALS AND METHODS: A literature review and content analysis was undertaken on patients' experiences of and preferences for surgical wound care discharge education. Four themes were uncovered in the literature (wound care discharge education, preferences for discharge education delivery, participation in wound care decisions and patient ability to manage their surgical wound to prevent wound complications), which guided item generation. Three types of validity testing occurred including: 1) face validity testing by the research team; 2) content validity testing (using Delphi study) with an international panel of experts including patients, clinicians and researchers; and 3) content validity (using pilot-testing) of the survey with seven patients from the target population. RESULTS: Initially 106 items were generated from the literature, and of these, 55 items were subjected to content validity testing by an international panel of 41 experts. After two Delphi rounds, 18 items were retained. Most patients provided limited and very minor feedback during pilot-testing. However, pilot-testing resulted in a revised survey administration plan to deliver the survey via telephone, including adding prompts and preambles to items. CONCLUSION: An 18-item survey comprised of three groups of items and an individual item was rigorously developed. The survey requires further testing among a larger sample of patients to confirm the items reflect important aspects of patients' experiences of and preferences for surgical wound care discharge education.

Patient experiences of, and preferences for, surgical wound care education.

The aim of this study was to describe patients' experiences of, and preferences for, surgical wound care discharge education and how these experiences predicted their ability to self-manage their surgical wounds. A telephone survey of 270 surgical patients was conducted across two hospitals two weeks after discharge. Patients preferred verbal (n = 255, 94.8%) and written surgical wound education (n = 178, 66.2%) from medical (n = 229, 85.4%) and nursing staff (n = 211, 78.7%) at discharge. The most frequent education content that patients received was information about follow-up appointments (n = 242, 89.6%) and who to contact in the community with wound care concerns (n = 233, 86.6%). Using logistic regression, patients who perceived that they participated in surgical wound care decisions were 6.5 times more likely to state that they were able to manage their wounds at home. Also, patients who agreed that medical and/or nursing staff discussed wound pain management were 3.1 times more likely to report being able to manage their surgical wounds at home. Only 40% (107/270) of patients actively participated in wound-related decision-making during discharge education. These results uncovered patient preferences, which could be used to optimise discharge education practices. Embedding patient participation into clinical workflows may enhance patients' self-management practices once home.

Development of a web-based discharge education intervention to improve the postdischarge recovery of general surgical patients.

BACKGROUND: Postoperative complications contribute to unplanned hospital readmissions, reoperations, and increased mortality for surgical patients. Discharge education for general surgical patients is often inadequate, and challenged by organizational, clinician and patient factors. PURPOSE: This research describes the development of the web-based discharge education intervention to improve patients' knowledge, skills, and confidence in self-managing their recovery after general surgery. METHODS: The intervention was informed by the UK Medical Research Council guidance for developing and evaluating complex interventions and Knowledge-to-Action framework, consisting of four iterative stages. Stakeholder engagement was undertaken throughout the development process and a logic model was utilized to map the working mechanism of the intervention. The concept of patient activation and Knowles adult learning theory underpinned the development process. RESULTS: The literature review and stakeholders' engagement in qualitative interviews and a series of meetings resulted in a web-based discharge education program with three different components: (1) post general surgery warning signs; (2) post general surgery everyday care instructions; and (3) animation video on wound potential wound complications. CONCLUSION: The web-based discharge education was developed according to the needs and preferences of healthcare providers and general surgical patients. Despite the rigorous and systematic approach used to develop the intervention, its effectiveness requires testing. CLINICAL RELEVANCE: This comprehensive iterative approach serves as a guide for others planning web-based interventions designed for surgical patients and the research approach used may inform those developing web-based interventions for other patient groups.

Incidence and predictors of surgical site infection in women who are obese and give birth by elective caesarean section: A secondary analysis.

BACKGROUND: Surgical site infection (SSI) after a caesarean section is of concern (CS) is of concern to both clinicians and women themselves. AIMS: The aim of this study is to identify the cumulative incidence and predictors of SSI in women who are obese and give birth by elective CS. MATERIALS AND METHODS: The method used was planned secondary analysis of data from women with a pre-pregnancy body mass index (BMI) ≥30 kg/m2 giving birth by elective CS in a multicentre randomised controlled trial of a prophylactic closed-incision negative pressure wound therapy dressing. Data were collected from medical records, direct observations of the surgical site and self-reported signs and symptoms from October 2015 to December 2019. The Centers for Disease Control and Prevention definition was used to identify SSI. Women were followed up once in hospital just before discharge and then weekly for four weeks after discharge. Blinded outcome assessors determined SSI. After the cumulative incidence of SSI was calculated, multiple variable logistic regression models were used to identify independent risk factors for SSI. RESULTS: SSI incidence in 1459 women was 8.4% (122/1459). Multiple variable-adjusted odds ratios (OR) for SSI were BMI ≥40 kg/m2 (OR 1.55, 95% confidence interval (CI) 1.30-1.86) as compared to BMI 30-34.9 0 kg/m2 , ≥2 previous pregnancies (OR 1.38, 95% CI 1.00-1.80) as compared to no previous pregnancies and pre-CS vaginal cleansing (OR 0.55, 95% CI 0.33-0.99). CONCLUSIONS: Our findings may inform preoperative counselling and shared decision-making regarding planned elective CS for women with pre-pregnancy BMI ≥30 kg/m2 .

Nurses' role in delivering discharge education to general surgical patients: A qualitative study.

AIMS: To explore nurses' perceived role and experience in providing discharge education to general surgical patients. DESIGN: Qualitative, using focus groups and face-to-face individual interviews. METHODS: Purposive sampling with maximum variation was used to recruit nurses from the general surgical wards in a tertiary hospital in Queensland, Australia. Semi-structured interviews (three focus groups and four individual interviews) were conducted with 21 nurses involved in delivering postoperative discharge education from August 2018 - July 2019. Interview data were analysed using inductive content analysis. RESULTS: Four themes emerged: assuming responsibility for patient education in the absence of discharge communication; supporting patients to participate in self-management after hospitalization; variability in the resources, content and delivery of discharge education; and meeting operational demands compromises the quality of patients' discharge education. CONCLUSION: This study highlights the importance of nurses' role and the challenges encountered in delivering effective discharge education. These findings can be used to identify strategies to enhance discharge communication among health professionals and standardize the delivery of education to improve surgical patients' postoperative outcomes. IMPACT: Ineffective discharge education contributes to patients' poor management of their postdischarge recovery. Developing an understanding of nurses' role in discharge education can inform policies and nursing practice to improve patients' well-being and reduce the potential for unplanned and emergency care.

General surgical patients' experience of hospital discharge education: A qualitative study.

AIMS AND OBJECTIVES: To explore adult general surgical patients' perceptions of, and satisfaction with, discharge education provided by healthcare providers. BACKGROUND: Discharge education is essential for general surgical patients as it equips them with the required knowledge and skills to engage in their care after discharge. Insufficient knowledge to self-manage or assess their symptoms can result in postdischarge complications, unplanned hospital readmission and overall dissatisfaction with the hospital experience. DESIGN: A constructivist-interpretivist paradigm using qualitative interviews. METHODS: Telephone interviews were conducted with 13 patients between August 2018 and November 2018 and analysed using inductive content analysis. COREQ guidelines were adopted for the conduct and reporting of the study. RESULTS: Four themes were uncovered: (a) The quality of discharge information influences patients' postdischarge experience; (b) The negative impact of contextual influences on delivery of discharge education; (c) Patients actively participating in their surgical journey; (d) Patients' preferences with the delivery of discharge education. CONCLUSION: Inadequate discharge education leads to patients' inability to self-manage their recovery process. Information sharing with patients fosters shared understanding towards goals and expectations. RELEVANCE TO CLINICAL PRACTICE: Understanding patients' view may inform the design of patient-centred discharge education interventions for patients to self-manage their recovery postdischarge.

Factors that influence the non-technical skills performance of scrub nurses: a prospective study.

AIM: To identify and describe the factors that impact on the performance of scrub nurses' non-technical skills performance during the intra-operative phase of surgery. BACKGROUND: Non-technical skills have been identified as important precursors to errors in the operating room. However, few studies have investigated factors influencing non-technical skills of scrub nurses. DESIGN: Prospective observational study. METHODS: Structured observations were performed on a sample of 182 surgical procedures across eight specialities by two trained observers from August 2012-April 2013 at two hospital sites. Participants were purposively selected scrub nurses. Bivariate correlations and a multiple linear regression model were used to identify associations among length of surgery, patients' acuity using the American Society of Anesthesiologists classification system, team familiarity, number of occasions scout nurses leave the operating room, change of scout nurse and the outcome, the non-technical skills performance of scrub nurses. RESULTS: Patient acuity and team familiarity were the strongest predictors of scrub nurses' non-technical skills performance at hospital site A. There were no correlations between the predictors and the performance of scrub nurses at hospital site B. CONCLUSION: A dedicated surgical team and patient acuity potentially influence the performance of scrub nurses' non-technical skills. Familiarity with team members foster advanced planning, thus minimizing distractions and interruptions that impact on scrub nurses' performance. Development of interventions aimed at improving non-technical skills has the potential to make a substantial difference and enhance patient care.

Use of Negative-Pressure Wound Dressings to Prevent Surgical Site Complications After Primary Hip Arthroplasty: A Pilot RCT.

PURPOSE: Negative-pressure wound therapy (NPWT) is increasingly used for primary surgical incisions despite the paucity of evidence. Study objectives were to assess the use of NPWT on surgical sites to prevent infections and other wound complications after elective primary hip arthroplasty and to consider feasibility of a larger trial. METHODS: A nonmasked, randomized controlled pilot trial. Patients were recruited preoperatively from the preadmission clinic of an Australian hospital during 2013-2014. Computer-generated randomization was performed with allocation concealed until completion of surgery. The intervention group received NPWT (PICO) while the control group received the standard care hydrocolloid, reinforced with 2 absorbent dressings. Patients were followed for 6 weeks for postoperative complications (infection, length of stay, readmission) and skin complications (bruising, seroma, hematoma, dehiscence). Feasibility end points included numbers recruited, randomized, and followed up; fidelity; and costs. RESULTS: Of 77 people approached, 76 were recruited, and 70 were randomized. Of 35 in the negative-pressure group, 2 received the standard dressing. Attrition at 6 weeks exceeded 10% in both groups. Dressing costs were lower in the control group ($3.01/d vs $38.40/d); SSI incidence was 2/35 in the NPWT and 3/35 in the control group (intention to treat: risk ratio [RR] = 0.67; 95% confidence interval [CI] = 0.12-3.7; P = .65). NPWT patients experienced more postoperative wound complications (RR = 1.6; 95% CI = 1.0-2.5; P = .04). CONCLUSION: A reduction of 3% in SSI incidence suggests that a definitive trial requires approximately 900 patients per group. Yet there is uncertainty around the benefit of NPWT after elective hip arthroplasty.

Postsurgery wound assessment and management practices: a chart audit.

AIMS AND OBJECTIVES: To examine wound assessment and management in patients following surgery and to compare these practices with current evidence-based guidelines for the prevention of surgical site infection across one healthcare services district in Queensland, Australia. BACKGROUND: Despite innovations in surgical techniques, technological advances and environmental improvements in the operating room, and the use of prophylactic antibiotics, surgical site infections remain a major source of morbidity and mortality in patients following surgery. DESIGN: A retrospective clinical chart audit METHODS: A random sample of 200 medical records of patients who had undergone surgery was undertaken over a two-year period (2010-2012). An audit tool was developed to collect the data on wound assessment and practice. The study was undertaken across one healthcare services district in Australia. RESULTS: Of the 200 records that were randomly identified, 152 (76%) met the inclusion criteria. The excluded records were either miscoded or did not involve a surgical incision. Of the 152 records included, 87 (57·2%) procedures were classified as 'clean' and 106 (69·7%) were elective. Wound assessments were fully documented in 63/152 (41·4%) of cases, and 59/152 (38·8%) charts had assessments documented on a change of patient condition. Of the 15/152 (9·9%) patients with charted postoperative wound complications, 4/15 (26·6%) developed clinical signs of wound infection, which were diagnosed on days 3 to 5. CONCLUSIONS: The timing, content and accuracy of wound assessment documentation are variable. Standardising documentation will increase consistency and clarity and contribute to multidisciplinary communication. RELEVANCE TO CLINICAL PRACTICE: These results suggest that postoperative wound care practices are not consistent with evidence-based guidelines. Consequently, it is important to involve clinicians in identifying possible challenges within the clinical environment that may curtail guideline use.

Exploring clinicians' insertion experience with a new peripheral intravenous catheter in the emergency department.

BACKGROUND: Hospitals frequently introduce new medical devices. However, the process of clinicians adapting to these new vascular access devices has not been well explored. The study aims to explore clinicians' experience with the insertion of a new guidewire peripheral intravenous catheter (PIVC) introduced in the emergency department (ED) setting. METHODS: The study was conducted at two EDs in Queensland, Australia, utilising a qualitative explorative approach. Interviews were conducted with guidewire PIVC inserters, including ED doctors and nurses, and field notes were recorded by research nurses during insertions. Data analysis was performed using inductive content analysis, from which themes emerged. RESULTS: The study compiled interviews from 10 participants and field notes from 191 observation episodes. Five key themes emerged, including diverse experience, barriers related to the learning process, factors influencing insertion success, and recommendations to enhance clinicians' acceptance. These themes suggest that the key to successful adoption by clinicians lies in designing user-friendly devices that align with familiar insertion techniques, facilitating a smooth transfer of learning. CONCLUSION: Clinician adaptation to new devices is vital for optimal patient care. Emergency nurses and doctors prefer simplicity, safety, and familiarity when it comes to new devices. Providing comprehensive device training with diverse training resources, hands-on sessions, and continuous expert support, is likely to enhance clinician acceptance and the successful adoption of new devices in ED settings.

End-of-life decision-making in the emergency department and intensive care unit: Health professionals' perspectives on and knowledge of the law in Queensland.

OBJECTIVE: To investigate ED and intensive care unit healthcare professionals' perspectives and knowledge of the law that underpins end-of-life decision-making in Queensland, Australia. METHODS: An online survey with questions about perspectives, perceived, and actual, knowledge of the law was distributed by the professional organisations of medical practitioners, nurses and social workers who work in Queensland EDs and intensive care units. RESULTS: The survey responses of 126 healthcare professionals were included in the final analysis. Most respondents agreed that the law was relevant to end-of-life decision-making, but that clinician and family consensus mattered more than following the law. Generally, doctors' legal knowledge was higher than nurses'; however, there were significant gaps in the knowledge of all respondents about the operation of advance health directives in Queensland. CONCLUSIONS: The legal framework that supports end-of-life decision-making for adults who lack decision-making capacity has been in place for more than two decades. Despite frequently being involved in making or enacting these decisions, gaps in the legal knowledge of healthcare professionals who work in EDs and intensive care units in Queensland are evident. Further research to better understand how to improve knowledge and application of the law is warranted.

Effectiveness of discharge education for patients undergoing general surgery: A systematic review and meta-analysis.

BACKGROUND: There is some evidence to suggest that discharge education may reduce the risk of postoperative complications, however, a critical evaluation of the body of evidence is needed. OBJECTIVE: To assess the effect of discharge education interventions versus standard education given to general surgery patients prior to, or up to 30-days of hospital discharge on clinical and patient-reported outcomes. DESIGN: Systematic review and meta-analysis. Clinical outcomes were 30-day surgical site infection incidence and re-admission up to 28 days. Patient-reported outcomes included patient knowledge, self-confidence, satisfaction, and quality of life. SETTING: Participants were recruited from hospitals. PARTICIPANTS: Adult general surgical patients. METHODS: MEDLINE (Pubmed), CINAHL (EBSCO), EMBASE (Elsevier) and the Cochrane Library were searched in February 2022. Randomised controlled trials and non-randomised studies of interventions published between 2010 and 2022, with adults undergoing general surgical procedures receiving discharge education on surgical recovery, including wound management, were eligible for inclusion. Quality appraisal was undertaken using the Cochrane Risk of Bias 2 and the Risk of Bias Assessment Tool for Nonrandomised Studies. The Grading of Assessment, Development, Recommendations, and Evaluation was used to assess the certainty of the body of evidence based on the outcomes of interest. RESULTS: Ten eligible studies (eight randomised control trials and two non-randomised studies of interventions) with 965 patients were included. Six randomised control trials assessed the effect of discharge education interventions on 28-day readmission (Odds ratio 0.88, 95 % confidence interval 0.56-1.38). Two randomised control trials assessed the effect of discharge education interventions on surgical site infection incidence (Odds ratio = 0.84, 95 % confidence interval 0.39-1.82). The results of the non-randomised studies of interventions were not pooled due to heterogeneity in outcome measures. The risk of bias was either moderate or high for all outcomes, and the body of evidence using GRADE was judged as very low for all outcomes studied. CONCLUSIONS: The impact of discharge education on the clinical and patient-reported outcomes of patients undergoing general surgery cannot be determined due to the uncertainty of the evidence base. Despite the increased use of web-based interventions to deliver discharge education to general surgery patients, larger samples in more rigorous multicentre randomised control trials with parallel process evaluations are needed to better understand the effect of discharge education on clinical and patient-reported outcomes. REGISTRATION: PROSPERO CRD42021285392. TWEETABLE ABSTRACT: Discharge education may reduce the likelihood of surgical site infection and hospital readmission but the body of evidence is inconclusive.

Evaluating the feasibility of a web-based discharge education programme to improve general surgical patients' postdischarge recovery: a pilot randomised controlled trial.

OBJECTIVE: To assess the feasibility of implementing a web-based discharge education programme for general surgery patients both prior to and after hospital discharge. DESIGN, SETTING AND PARTICIPANTS: This is a prospective, two-arm, pilot randomised controlled trial. Patients who had a general surgery procedure were recruited from a tertiary hospital between October 2020 and January 2021. Patients were randomly assigned to either the standard education or the web-based education intervention. INTERVENTION: The web-based education comprised of three components designed to enhance patients' knowledge, skills and confidence to improve their engagement with self-care, and the ability to detect any postoperative issues that can arise during the postdischarge period. MAIN OUTCOMES AND MEASURES: The primary outcome was feasibility in terms of recruitment, randomisation, retention and treatment fidelity related to intervention delivery, adherence and satisfaction. Secondary outcomes were patient activation, self-care ability and unplanned healthcare utilisation. RESULTS: Eighty-five patients were recruited and randomised (42 control; 43 intervention). Twenty-three (27%) were lost to follow-up. All patients received their group allocation as randomised and all patients in the intervention group received the web-based education prior to discharge. Postdischarge, patients accessed the education an average of 3 times (SD 3.14), with 4 minutes (SD 16) spent on the website. 28 (97%) of the intervention patients found the content easy to understand, 25 (86%) found it useful and 24 (83%) were satisfied with its content. There was a significant association between the intervention and patient activation (F(1,60)=9.347, p=0.003), but not for self-care ability and unplanned healthcare utilisations. CONCLUSION: This pilot study demonstrated the feasibility of implementing a web-based education programme. There was a high number of participants lost to follow-up, requiring additional attention in the design and implementation of a larger trial. TRIAL REGISTRATION NUMBER: ACTRN12620000389909p.

Incidence and risk factors for surgical wound complications in women with body mass index >30 kg/m2 following cesarean delivery: a secondary analysis.

BACKGROUND: Surgical wound complications are common and occur in between 3% and 12% of obese women after cesarean delivery. An understanding of the risk factors for wound complications may inform potential areas for clinical care improvement. OBJECTIVE: This study aimed to identify the incidence and predictors of surgical wound complications in obese women after cesarean delivery. STUDY DESIGN: This was a secondary analysis of the ADding negative pRESSure to improve healING, or DRESSING, randomized controlled trial conducted at 4 maternity hospitals in Australia. A total of 2035 women with a prepregnancy body mass index ≥30 kg/m2 undergoing cesarean delivery were included. Data were collected between October 2015 and December 2019 using self-reporting of signs and symptoms, the research nurses' direct observation of the surgical site, and medical records. Independent blinded outcome assessors ascertained wound outcomes on the basis of self-reported data and medical records. Multivariable logistic regression models were used to identify independent risk factors for wound complications and surgical wound dehiscence. The 30-day cumulative incidence of wound complications and surgical wound dehiscence was calculated. RESULTS: Of the 2035 women, 317 (15.6%) developed a wound complication, whereas 211 (10.4%) developed surgical wound dehiscence. The predictors of a wound complication included 1 previous cesarean delivery (odds ratio, 1.41; 95% confidence interval, 1.05-1.90; P=.02) and ruptured membranes >12 hours (odds ratio, 1.69; 95% confidence interval, 1.08-2.66; P=.02). The odds of developing any wound complication decreased by 45% with vaginal cleansing (odds ratio, 0.55; 95% confidence interval, 0.42-0.72; P<.001) and by 59% for low transverse incision (odds ratio, 0.41; 95% confidence interval, 0.18-0.94; P=.04). The predictors of surgical wound dehiscence included 1 previous cesarean delivery (odds ratio, 1.62; 95% confidence interval, 1.14-2.31; P=.008) and ruptured membranes >12 hours (odds ratio, 1.85; 95% confidence interval, 1.10-3.12; P=.02). The odds of developing surgical wound dehiscence decreased by 50% for vaginal cleansing (odds ratio, 0.50; 95% confidence interval, 0.36-0.69; P<.001) and by 42% for using a double-layer uterine closure (odds ratio, 0.58; 95% confidence interval, 0.35-0.97; P=.04). CONCLUSION: Wound complications and surgical wound dehiscence in this population are high. The predictors observed herein would assist in identifying high-risk women. Such information may guide patient-centered decision-making in the planning of surgical births and individualized postoperative care.

Effects of a Brief Team Training Program on Surgical Teams' Nontechnical Skills: An Interrupted Time-Series Study.

BACKGROUND: Up to 60% of adverse events in surgery are the result of poor communication and teamwork. Nontechnical skills in surgery (NOTSS) are critical to the success of surgery and patient safety. The study aim was to evaluate the effect of a brief team training intervention on teams' observed NOTSS. METHODS: Pretest-posttest interrupted time-series design with statistical process control analysis was used to detect longitudinal changes in teams' NOTSS. We evaluated NOTSS using the revised NOTECHS weekly for 20 to 25 weeks before and after implementation of a team training program. RESULTS: We observed 179 surgical procedures with cardiac, vascular, upper gastrointestinal, and hepatobiliary teams. Mean posttest NOTECHS scores increased across teams, showing special cause variation. There were also significant before and after improvements in NOTECHS scores in respect to professional role and in the use of the Surgical Safety Checklist. CONCLUSIONS: Our results suggest associated improvements in teams' NOTSS after implementation of the team training program.

Closed incision negative pressure wound therapy versus standard dressings in obese women undergoing caesarean section: multicentre parallel group randomised controlled trial.

OBJECTIVE: To determine the effectiveness of closed incision negative pressure wound therapy (NPWT) compared with standard dressings in preventing surgical site infection (SSI) in obese women undergoing caesarean section. DESIGN: Multicentre, pragmatic, randomised, controlled, parallel group, superiority trial. SETTING: Four Australian tertiary hospitals between October 2015 and November 2019. PARTICIPANTS: Eligible women had a pre-pregnancy body mass index of 30 or greater and gave birth by elective or semi-urgent caesarean section. INTERVENTION: 2035 consenting women were randomised before the caesarean procedure to closed incision NPWT (n=1017) or standard dressing (n=1018). Allocation was concealed until skin closure. MAIN OUTCOME MEASURES: The primary outcome was cumulative incidence of SSI. Secondary outcomes included depth of SSI (superficial, deep, or organ/body space), rates of wound complications (dehiscence, haematoma, seroma, bleeding, bruising), length of stay in hospital, and rates of dressing related adverse events. Women and clinicians were not masked, but the outcome assessors and statistician were blinded to treatment allocation. The pre-specified primary intention to treat analysis was based on a conservative assumption of no SSI for a minority of women (n=28) with missing outcome data. Post hoc sensitivity analyses included best case analysis and complete case analysis. RESULTS: In the primary intention to treat analysis, SSI occurred in 75 (7.4%) women treated with closed incision NPWT and in 99 (9.7%) women with a standard dressing (risk ratio 0.76, 95% confidence interval 0.57 to 1.01; P=0.06). Post hoc sensitivity analyses to explore the effect of missing data found the same direction of effect (closed incision NPWT reducing SSI), with statistical significance. Blistering occurred in 40/996 (4.0%) women who received closed incision NPWT and in 23/983 (2.3%) who received the standard dressing (risk ratio 1.72, 1.04 to 2.85; P=0.03). CONCLUSION: Prophylactic closed incision NPWT for obese women after caesarean section resulted in a 24% reduction in the risk of SSI (3% reduction in absolute risk) compared with standard dressings. This difference was close to statistical significance, but it likely underestimates the effectiveness of closed incision NPWT in this population. The results of the conservative primary analysis, multivariable adjusted model, and post hoc sensitivity analysis need to be considered alongside the growing body of evidence of the benefit of closed incision NPWT and given the number of obese women undergoing caesarean section globally. The decision to use closed incision NPWT must also be weighed against the increases in skin blistering and economic considerations and should be based on shared decision making with patients.

Discharge education delivered to general surgical patients in their management of recovery post discharge: A systematic mixed studies review.

BACKGROUND: Discharge education is essential for postoperative general surgery patients for their self-management of care at home post discharge. The first 30 days' post-surgery is pivotal to the post-operative recovery process as this is when most post-operative complications occur. Insufficient discharge education can compromise patients' recovery process causing postoperative complications and unplanned hospital readmissions. OBJECTIVES: To identify the discharge education provided to general surgery patients. DESIGN: Systematic mixed studies review. DATA SOURCES: Literature data sources were searched from December 2017 to January 2018 using the four databases: EBSCO CINAHL Plus, EBSCO MEDLINE, Ovid EMBASE and COCHRANE Library. Searches were supplemented with hand searching of reference lists. REVIEW METHODS: The relevance of the articles was reviewed using the inclusion and exclusion criteria; included data were extracted and presented in a summary table. Two reviewers appraised the methodological quality of the articles using the Mixed Methods Appraisal Tool. Discussions were held to examine emergent themes, quality scores of the studies, and agreement reached by consensus. Themes were derived through inductive analysis. RESULTS: A total of 468 records were screened for titles and abstracts and 7 studies met the inclusion criteria. There was a mix of qualitative and quantitative studies. The majority of the included sample were patients with one quantitative study including patients' family and nurses. Discharge education was delivered at various timing and at different doses during the surgical process. Education delivered was mostly standardised and some of the discharge interventions were tailored and included a checklist for stoma care and a discharge warning tool. Four themes were identified: quality of discharge education influences its uptake, health care professionals' perceptions of their role in the delivery of discharge education to patients, patients' preferences for education delivery and patients' participation in their self-care. CONCLUSIONS: The quality of discharge education has an influence on patient participation in their management of care post discharge. Assessing patients' preparedness for discharge is an essential component of discharge planning process. The presentation, timing and frequency of discharge education was important in the delivery of information. Tailored education reflecting the learning needs of patients using multiple media delivered in varying doses enhanced patients' overall knowledge for successful management of recovery post discharge. The scarcity of recent literature in discharge education indicates that the quantity of evidence regarding discharge education intervention in general surgery patients is low and further work in this area needs to be undertaken.

Changes in surgical team performance and safety climate attitudes following expansion of perioperative services: a repeated-measures study.

Objective The aim of the present study was to describe process changes in surgical team performance and team members' attitudes to safety culture following hospital relocation and expansion of perioperative services. Methods The study was a naturalistic study using structured observations and surveys to assess non-technical skills (NTS; i.e. communication, teamwork, situational awareness, decision making and leadership) in surgery. This interrupted time series design used mixed-linear regression models to examine the effect of phase (before and after hospital relocation) on surgical teams' NTS and their processes that may affect performance. Differences in self-reported teamwork and safety climate attitudes were also examined. Results In all, 186 procedures (100 before and 81 after hospital relocation) were observed across teams working in general, paediatric, orthopaedic and thoracic surgeries. Interobserver agreement ranged from 86% to 95%. An effect of phase was found, indicating that there were significant improvements after relocation in the use of NTS by the teams observed (P=0.020; 95% confidence interval 1.9-4.7). Conclusions The improvements seen in surgical teams' NTS performance and safety culture attitudes may be related to the move to a new state-of-the-art perioperative department. What is known about the topic? Patient safety in surgery relies on optimal team performance, underpinned by effective NTS. What does this paper add? The NTS of surgical teams may be improved through ergonomic innovations that promote teams' shared mental models. What are the implications for practitioners? Effective multidisciplinary teamwork relies on a combination of NTS and ergonomic factors, which inherently contribute to team performance and safety climate attitudes.

Evaluation of a Brief Team Training Intervention in Surgery: A Mixed-Methods Study.

The aim of this study was to evaluate a brief team training program in relation to teams' observed nontechnical skills (NTSs) in surgery, teams' perceptions of safety culture, and the training implementation. We used mixed methods to analyze structured observations of 179 surgeries, semistructured interviews with surgical team members from four selected surgical specialties, and a survey. There were significant (P < .001) improvements in surgical teams' observed NTSs and in the use of the World Health Organization's Surgical Safety Checklist after participation in the training program. Nonsignificant results included increased perceived safety climate and decreased perceived teamwork climate. From participant interviews, we identified that production pressure and time constraints were the biggest barriers to implementation and the greatest enabler was the organization's support for staff education initiatives. Most participants perceived the content of the program to be useful. These results highlight the complexities inherent in the development and evaluation of interdisciplinary patient safety interventions.
