Impact of the WHO Surgical Safety Checklist Relative to Its Design and Intended Use: A Systematic Review and Meta-Meta-Analysis

BackgroundThe aim of this study was to identify what parts of the World Health Organization Surgical Safety Checklist (WHO SSC) are working, what can be done to make it more effective, and to determine if it achieved its intended effect relative to its design and intended use. Study DesignWe conducted a qualitative thematic analysis and meta-meta-analyses of findings in WHO SSC systematic reviews following Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Results Twenty systematic reviews were included for qualitative thematic analysis. Narrative information was coded in 4 primary areas with a focus on impact of the WHO SSC. Four themes—Clinical Outcomes, Process Measures, Team Dynamics and Communication, and Safety Culture—pertained directly to the aims or purposes behind the development of the SSC. The other 2 themes—Efficiency and Workload involved in using the checklist and Checklist Impact on Institutional Practices—are associated with SSC use, but were not focal areas considered during its development. Included in the 20 systematic reviews were 24 unique observational cohort studies that reported pre-post data on a total of 18 clinical outcomes. Mortality, morbidity, surgical site infection, pneumonia, unplanned return to the operating room, urinary tract infection, blood loss requiring transfusion, unplanned intubation, and sepsis favored the use of the WHO SSC. Deep vein thrombosis was the only postoperative outcome assessed that did not favor use of the WHO SSC. ConclusionsThe WHO SSC positively impacts the things it was explicitly designed to address and does not positively impact things it was not explicitly designed for

Impact of implementing a fast-track protocol and standardized guideline for the management of pediatric appendicitis

Background: In 2017, a provincial guideline was created to fast track and standardize care for pediatric appendicitis in Alberta. We conducted a study to determine the impact of implementation of the guideline at our institution on length of stay (LOS), antibiotic stewardship efforts and costs. Methods: We performed a retrospective review of the charts of all patients younger than 18 years of age who underwent appendectomy at our institution in 2 periods: before guideline implementation (Dec. 1, 2016, to May 31, 2017) and after implementation (Dec. 1, 2017, to May 31, 2018). We compared LOS, duration of antibiotic therapy, 30-day postdischarge complication rates and variable cost between the 2 cohorts. Results: Of the 276 total appendectomy procedures performed, 185 were for simple appendicitis (81 before guideline implementation and 104 after implementation), and 91 were for complicated appendicitis (44 and 47, respectively). The median LOS was shorter in the postimplementation cohort for both simple and complicated appendicitis (15.5 h [interquartile range (IQR) 12-19 h] v. 17.0 h [IQR 13-22 h], p = 0.03; and 3.0 d [IQR 2-4 d] v. 3.0 d [IQR 3-5 d], p = 0.05, respectively). Patients with complicated appendicitis had fewer antibiotic days after guideline implementation; the difference was statistically significant for patients without diffuse peritoneal contamination or abscess formation (p = 0.02). There were no differences between the cohorts with respect to 30-day rates of complications, including emergency department visits, readmission and surgical site infections. After guideline implementation, the average variable cost per patient was reduced by $230, equating to a total average annual cost savings of$75 842 for our institution. Conclusion: The implementation of a provincial guideline aimed at standardizing care in pediatric appendicitis at our institution was associated with shortened LOS, improved antibiotic stewardship efforts and reduced cost of care. Other institutions may replicate our model of a standardized pathway in the management of pediatric appendicitis in an effort to improve the quality of patient care and reduce health care costs

Treatment options for pediatric patent ductus arteriosus: Systematic review and meta-analysis

BACKGROUND: Patent ductus arteriosus (PDA) in the nonpremature pediatric patient is currently treated by surgical ligation or catheter occlusion. There is no clear superiority of one technique over the other. This meta-analysis compares the clinical outcomes of the two treatment options for PDA. METHODS: We performed a literature search of MEDLINE, Embase, PubMed, and the Cochrane database of randomized controlled trials (RCTs) that took place between 1950 and February 2014 and hand-searched references from included studies. We excluded studies of adult or premature patients and those without a direct comparison between surgical and catheter-based treatments of PDAs. Outcomes of interest were reintervention, total complications, length of stay, and cost. RESULTS: One thousand three hundred thirty-three manuscripts were screened. Eight studies fulfilled the inclusion criteria (one RCT and seven observational studies [N = 1,107]). In pooled observational studies, there were significantly decreased odds (OR, 0.12; 95% CI, 0.03-0.42) for reintervention in the surgical ligation group but insignificantly higher odds for overall complications (OR, 2.01; 95% CI, 0.68-5.91). There were no complications reported in the RCT, but surgical ligation was associated with decreased odds for reintervention and a longer length of stay. Funnel plots revealed a possible publication bias and a quality review identified comparability bias. CONCLUSIONS: Both therapies have comparable outcomes. Reintervention is more common with catheter-based treatment, but overall complication rates are not higher and hospital stay is shorter. Our data span \u3e 2 decades and may not reflect current surgical and catheterization outcomes. Large, randomized, prospective studies may help determine the optimal treatment strategy

Refining Successful Implementation Strategies for the Surgical Safety Checklist in High-Income Contexts: Results of an International Mixed Methods Study

The WHO Surgical Safety Checklist (SSC) continues to show inconsistent success in reducing surgical complications in high-income settings. Previous implementation research identified potential barriers and facilitators to success, but it primarily consists of qualitative studies with small sample sizes in limited geographic areas. We conducted a multi-country mixed-methods study of barriers and facilitators to SSC implementation to better inform policies and practices for improving SSC buy-in and use to maximize its impact. This convergent parallel mixed-methods study utilized survey and interview data from surgical team members practicing in five countries. Survey data were analyzed using χ2 analysis or Fisher’s exact test for categorical variables and McNemar’s test to analyze differences between related groups for dichotomous variables. Interview data underwent inductive coding followed by thematic analysis for predominant themes common across the study countries. The study resulted in 2,032 survey responses and 51 interviews. Facilitators to success included having influential multi-disciplinary champions from surgery, anesthesiology, and nursing; using a distributed leadership process to promote ownership across all surgical team members; and providing education on the “why” of the checklist. Practitioners found patient safety metrics (e.g., wrong side surgery) more relevant than clinical outcome measures (e.g., surgical mortality) to assess SSC success. Finally, auditing for process engagement was felt to promote more meaningful use than auditing for checklist completion. Our international examination of barriers and facilitators to successful SSC implementation has identified more specific guidance for high-income settings that integrate people, data, and processes

Effectiveness and meaningful use of paediatric surgical safety checklists and their implementation strategies: a systematic review with narrative synthesis

Objective: To examine the effectiveness and meaningful use of paediatric surgical safety checklists (SSCs) and their implementation strategies through a systematic review with narrative synthesis. Summary background data Since the launch of the WHO SSC, checklists have been integrated into surgical systems worldwide. Information is sparse on how SSCs have been integrated into the paediatric surgical environment. Methods: A broad search strategy was created using Pubmed, Embase, CINAHL, Cochrane Central, Web of Science, Science Citation Index and Conference Proceedings Citation Index. Abstracts and full texts were screened independently, in duplicate for inclusion. Extracted study characteristic and outcomes generated themes explored through subgroup analyses and idea webbing. Results: 1826 of 1921 studies were excluded after title and abstract review (kappa 0.77) and 47 after full-text review (kappa 0.86). 20 studies were of sufficient quality for narrative synthesis. Clinical outcomes were not affected by SSC introduction in studies without implementation strategies. A comprehensive SSC implementation strategy in developing countries demonstrated improved outcomes in high-risk surgeries. Narrative synthesis suggests that meaningful compliance is inconsistently measured and rarely achieved. Strategies involving feedback improved compliance. Stakeholder-developed implementation strategies, including team-based education, achieved greater acceptance. Three studies suggest that parental involvement in the SSC is valued by parents, nurses and physicians and may improve patient safety. Conclusions: A SSC implementation strategy focused on paediatric patients and their families can achieve high acceptability and good compliance. SSCs’ role in improving measures of paediatric surgical outcome is not well established, but they may be effective when used within a comprehensive implementation strategy especially for high-risk patients in low-resource settings

Consensus Guidelines for Perioperative Care in Neonatal Intestinal Surgery: Enhanced Recovery After Surgery (ERAS\u3csup\u3e®\u3c/sup\u3e) Society Recommendations

Background: Enhanced Recovery After Surgery (ERAS®) Society guidelines integrate evidence-based practices into multimodal care pathways that have improved outcomes in multiple adult surgical specialties. There are currently no pediatric ERAS® Society guidelines. We created an ERAS® guideline designed to enhance quality of care in neonatal intestinal resection surgery. Methods: A multidisciplinary guideline generation group defined the scope, population, and guideline topics. Systematic reviews were supplemented by targeted searching and expert identification to identify 3514 publications that were screened to develop and support recommendations. Final recommendations were determined through consensus and were assessed for evidence quality and recommendation strength. Parental input was attained throughout the process. Results: Final recommendations ranged from communication strategies to antibiotic use. Topics with poor-quality and conflicting evidence were eliminated. Several recommendations were combined. The quality of supporting evidence was variable. Seventeen final recommendations are included in the proposed guideline. Discussion: We have developed a comprehensive, evidence-based ERAS guideline for neonates undergoing intestinal resection surgery. This guideline, and its creation process, provides a foundation for future ERAS guideline development and can ultimately lead to improved perioperative care across a variety of pediatric surgical specialties

Hyperpolarized 13C-MRI of Tumor Metabolism Demonstrates Early Metabolic Response to Neoadjuvant Chemotherapy in Breast Cancer

Purpose: To compare hyperpolarized carbon-13 (13C)-MRI with dynamic contrast-enhanced MRI (DCE-MRI) for detecting early treatment response in breast cancer. Materials and Methods: In this institutional review board-approved prospective study, one woman with triple-negative breast cancer (age 49) underwent 13C-MRI following injection of hyperpolarized [1-13C]pyruvate and DCE-MRI at 3 T at baseline and after a single cycle of neoadjuvant therapy. The 13C-lactate/13C-pyruvate ratio derived from hyperpolarized 13C-MRI and the pharmacokinetic parameters Ktrans and kep derived from DCE-MRI were compared, before and after treatment. Results: Exchange of the 13C-label between injected hyperpolarized [1-13C]pyruvate and the endogenous lactate pool was demonstrated, catalyzed by the enzyme lactate dehydrogenase. After one cycle of neoadjuvant chemotherapy, a 34% reduction in the 13C-lactate/13C-pyruvate ratio was shown to correctly identify the patient as a responder to therapy, which was subsequently confirmed by a complete pathologic response. However, DCE-MRI showed an increase in the pharmacokinetic parameters Ktrans (132%) and kep (31%), which could be incorrectly interpreted as a poor response to treatment. Conclusion: Hyperpolarized 13C-MRI successfully identified response in breast cancer after a single cycle of neoadjuvant chemotherapy and may improve response prediction when used in conjunction with multiparametric proton MRI.This work was supported by a Wellcome Trust Strategic Award, Cancer Research UK (CRUK; Grants C8742/A18097, C19212/ A16628, C19212/A911376, and C197/A16465), the Austrian Science Fund (Grant J4025-B26), the CRUK Cambridge Centre, the CRUK & Engineering and Physical Sciences Research Council Cancer Imaging Centre in Cambridge and Manchester, the Mark Foundation for Cancer Research and Cancer Research UK Cambridge Centre (Grant C9685/A25177), CRUK National Cancer Imaging Translational Accelerator Award, Addenbrooke’s Charitable Trust, the National Institute for Health Research Cambridge Biomedical Research Centre, Cambridge Experimental Cancer Medicine Centre, and Cambridge University Hospitals National Health Service Foundation Trust

Association of a sequence variant in DAB2IP with coronary heart disease

Aims: A sequence variant, rs7025486[A], in DAB2IP on chromosome 9q33 has recently been associated with coronary heart disease (CHD). We sought to replicate this finding and to investigate associations with a panel of inflammatory and haemostatic biomarkers. We also sought to examine whether this variant, in combination with a chromosome 9p21 CHD variant (rs10757278) and the Framingham risk score (FRS), could improve the prediction of events compared with the FRS alone. Methods and results: rs7025486 was genotyped in 1386 CHD cases and 3532 controls and was associated with CHD [odds ratio (OR) of 1.16, 95% confidence interval (CI) 1.05-1.29, P = 0.003]. Meta-analysis, using data from the original report and from genome-wide association studies in both the Wellcome Trust Case Control Consortium and the Cardiovascular Health Study, comprising 9968 cases and 20 048 controls, confirmed the association (OR of 1.10, 95% CI 1.06-1.14, P = 3.2 x 10 -6). There was no association with a panel of CHD biomarkers, including any lipid, inflammation, or coagulation trait, nor with telomere length. Addition to the FRS of this variant plus rs10757278 on chromosome 9p21 improved the area under the receiver-operating characteristic curve (AROC) from 0.61 to 0.64 (P = 0.03) as well as improving the reclassification (net reclassification index = 11.1%, P = 0.007). Conclusion: This study replicates a previous association of a variant in DAB2IP with CHD. Addition of multiple variants improves the performance of predictive models based upon classical cardiovascular risk factors

Contemporary accuracy of death certificates for coding prostate cancer as a cause of death : Is reliance on death certification good enough? A comparison with blinded review by an independent cause of death evaluation committee

BACKGROUND: Accurate cause of death assignment is crucial for prostate cancer epidemiology and trials reporting prostate cancer-specific mortality outcomes. METHODS: We compared death certificate information with independent cause of death evaluation by an expert committee within a prostate cancer trial (2002-2015). RESULTS: Of 1236 deaths assessed, expert committee evaluation attributed 523 (42%) to prostate cancer, agreeing with death certificate cause of death in 1134 cases (92%, 95% CI: 90%, 93%). The sensitivity of death certificates in identifying prostate cancer deaths as classified by the committee was 91% (95% CI: 89%, 94%); specificity was 92% (95% CI: 90%, 94%). Sensitivity and specificity were lower where death occurred within 1 year of diagnosis, and where there was another primary cancer diagnosis. CONCLUSIONS: UK death certificates accurately identify cause of death in men with prostate cancer, supporting their use in routine statistics. Possible differential misattribution by trial arm supports independent evaluation in randomised trials
