Quality of life and healthcare utilisation improvements after atrial fibrillation ablation.

OBJECTIVE: Pulmonary vein isolation (PVI) guided by a standardised CLOSE (contiguous optimised lesions) protocol has been shown to increase clinical success after catheter ablation for paroxysmal atrial fibrillation (PAF). This study analysed healthcare utilisation and quality of life (QOL) outcomes from a large multicentre prospective study, measured association between QOL and atrial fibrillation (AF) burden and identified factors associated with lack of QOL improvement. METHODS: CLOSE-guided ablation was performed in 329 consecutive patients (age 61.4 years, 60.8% male) with drug-refractory PAF in 17 European centres. QOL was measured at baseline and 12 months post-ablation via Atrial Fibrillation Effect on QualiTy of Life Survey (AFEQT) and EuroQoL EQ-5D-5L questionnaires. All-cause and cardiovascular hospitalisations and cardioversions over 12 months pre-ablation and post-ablation were recorded. Rhythm monitoring included weekly and symptom-driven trans-telephonic monitoring, plus ECG and Holter monitoring at 3, 6 and 12 months. AF burden was defined as the percentage of postblanking tracings with an atrial tachyarrhythmia ≥30 s. Continuous measures across multiple time points were analysed using paired t-tests, and associations between various continuous measures were analysed using independent sample t-tests. Each statistical test used two-sided p values with a significance level of 0.05. RESULTS: Both QOL instruments showed significant 12-month improvements across all domains: AFEQT score increased 25.1-37.5 points and 33.3%-50.8% fewer patients reporting any problem across EuroQoL EQ-5D-5L domains. Overall, AFEQT improvement was highly associated with AF burden (p=0.009 for <10% vs ≥10% burden, p<0.001 for <20% vs ≥20% burden). Cardiovascular hospitalisations were significantly decreased after ablation (42%, p=0.001). Patients without substantial improvement in AFEQT (55/301, 18.2%) had higher AFEQT and CHA2DS2-VASc scores at baseline, and higher AF burden following PVI. CONCLUSIONS: QOL improved and healthcare utilisation decreased significantly after ablation with a standardised CLOSE protocol. QOL improvement was significantly associated with impairment at baseline and AF burden after ablation. TRIAL REGISTRATION NUMBER: NCT03062046.

Perioperative Outcomes After Tracheostomy Placement Among Complex Pediatric Patients.

OBJECTIVES/HYPOTHESIS: To compare perioperative outcomes after pediatric tracheostomy placement based on patient complexity. STUDY DESIGN: Retrospective case series. METHODS: All patients that underwent tracheostomy placement at a tertiary children's hospital between 2015 and 2019 were followed. Children with a history of major cardiac surgery, sepsis, or total parental nutrition (TPN) were grouped as complex. Admission length, tracheostomy-related complications, in-hospital mortality, and 30-day readmissions were recorded among complex and non-complex patients. RESULTS: A total of 238 children were included. Mean age at tracheostomy was 39.9 months (SD: 61.3), 51% were male and 51% were complex. Complex patients were younger at admission (29.9 vs. 46.8 months, P = .03), more likely to have respiratory failure (81% vs. 53%, P < .001) and more often required mechanical ventilation at discharge (86% vs. 67%, P < .001). An additional 33 days after placement was required for complex children (95% CI: 14-51, P = .001) and this group had more deaths (8% vs. 1%, P = .02); however, both groups had similar complication and readmission rates (P > .05). Total charges were higher among complex patients ($700,267 vs. $338,937, P < .001). Parametric survival analysis identified mechanical ventilation and patient complexity interacting to predict post-tracheostomy admission length. CONCLUSIONS: Hospital discharge after pediatric tracheostomy was associated with patient complexity and further influenced by mechanical ventilation. Recognition that cardiac surgery, sepsis, or TPN can predict poorer perioperative outcomes can provide quality improvement strategies for these vulnerable children.

Editor's Choice - Sex Related Differences in Peri-operative Mortality after Elective Repair of an Asymptomatic Abdominal Aortic Aneurysm in the Netherlands: a Retrospective Analysis of 2013 to 2018.

OBJECTIVE: The aim was to compare peri-operative (30 day and/or in hospital) mortality between women and men in the Netherlands after elective repair of an asymptomatic abdominal aortic aneurysm (AAA). METHODS: This was a retrospective study using data from the Dutch Surgical Aneurysm Audit (DSAA), a mandatory nationwide registry of patients undergoing AAA repair in the Netherlands. Patients who underwent elective open surgical (OSR) or endovascular aneurysm repair (EVAR) of an asymptomatic abdominal aortic aneurysm (AAA) between 2013 and 2018 were included. Absolute risk differences (ARDs) with 95% confidence intervals (CIs) in peri-operative mortality between women and men were estimated. Logistic regression analyses were performed to estimate adjusted odds ratios (ORs) for mortality. Confounders included pre-operative cardiac and pulmonary comorbidity, serum haemoglobin, serum creatinine, type of AAA repair, and AAA diameter. RESULTS: Some 1662 women and 9637 men were included, of whom 507 (30.5%) women and 2056 (21.3%) men underwent OSR (p < .001). Crude peri-operative mortality was 3.01% in women and 1.60% in men (ARD = 1.41%, 95% CI 0.64-2.37). This significant difference was also observed for OSR (ARD = 2.63%, 95% CI 0.43-5.36), but not for EVAR (ARD = 0.36%, 95% CI -0.16 to 1.17). Female sex remained associated with peri-operative mortality after adjusting for confounders (OR = 1.79, 95% CI 1.20-2.65, p = .004), which was similarly observed for OSR (OR = 1.85, 95% CI 1.16-2.94, p = .01), but not for EVAR (OR = 1.46, 95% CI 0.72-2.95, p = .29). CONCLUSIONS: Peri-operative mortality after elective repair of an asymptomatic AAA in the Netherlands is higher in women than in men. This disparity might be explained by the higher peri-operative mortality in women undergoing OSR, because no such difference was found in patients undergoing EVAR. Yet, it is likely that there are unaccounted factors at play since female sex remained significantly associated with mortality after adjusting for type of repair.

Systematic review and meta-analysis of robotic versus open hepatectomy.

BACKGROUND: To date, there are few studies comparing the outcomes of robotic hepatectomy (RH) versus open hepatectomy (OH). We report the first systematic review and meta-analysis comparing the outcomes of RH versus OH. METHODS: A systemic review was performed of all comparative studies of RH versus OH that reported the perioperative outcome(s) of interest. RESULTS: Seven retrospective cohort studies were included. There was no significant difference in patients' baseline characteristics. RH was associated with a longer operation time (mean difference (MD) 61.47 min; 95% confidence interval (CI) (7.03, 115.91); P = 0.03), shorter hospital stay (MD -2.57 days; 95% CI (-3.31, -1.82); P < 0.001), lower costs, less overall (risk ratio (RR) 0.63; 95% CI (0.46, 0.86); P = 0.004), minor (RR 0.64; 95% CI (0.43, 0.95); P = 0.03) and major (RR 0.45; 95% CI (0.22, 0.94); P = 0.03) post-operative complications compared to OH. CONCLUSION: RH had superior perioperative outcomes and was not cost prohibitive compared to OH, but had longer operation times.

Closure of Large Percutaneous Femoral Venous Access Using a Modified "Figure-of-Eight" Suture.

Recent advances in different percutaneous treatments made insertion of large-caliber sheaths in the femoral veins more common. Venous punctures are historically managed by initial manual compression with subsequent application of a compression bandage and bed rest. We describe a modified "figure-of-eight" suture technique for minimizing the risk of accidental puncture of the vein while grabbing the subcutaneous tissue. We examined the safety and feasibility of this technique combined with early mobilization in a real-world setting. We performed a retrospective analysis on 56 consecutive patients undergoing percutaneous mitral valve repair using large femoral venous access. The patient population was heterogeneous and bleeding risk characteristics were common. Bleeding Academic Research Consortium Consensus (BARC)-classifiable bleeding complications occurred in eight patients (14%), BARC of two events or more in five patients (8.9%), and BARC of three or more event in only one patient (1.8%), which is a comparable success rate to large venous access closure with suture-mediated closure devices. No BARC Type 3b or BARC Type 5 bleeding occurred. During routine clinical follow-up, no groin-related problems were reported in all patients. Closure of large femoral venous access using a modified temporary subcutaneous figure-of-eight suture in combination of a light compression bandage and bed rest for 2 to 4 hours provides a safe and low-cost alternative to closure devices for early mobilization.

Validation of the All Patient Refined Diagnosis Related Group (APR-DRG) Risk of Mortality and Severity of Illness Modifiers as a Measure of Perioperative Risk.

The All Patient Refined Diagnosis Related Group (APR-DRG) is an inpatient visit classification system that assigns a diagnostic related group, a Risk of Mortality (ROM) subclass and a Severity of Illness (SOI) subclass. While extensively used for cost adjustment, no study has compared the APR-DRG subclass modifiers to the popular Charlson Comorbidity Index as a measure of comorbidity severity in models for perioperative in-hospital mortality. In this study we attempt to validate the use of these subclasses to predict mortality in a cohort of surgical patients. We analyzed all adult (age over 18 years) inpatient non-cardiac surgery at our institution between December 2005 and July 2013. After exclusions, we split the cohort into training and validation sets. We created prediction models of inpatient mortality using the Charlson Comorbidity Index, ROM only, SOI only, and ROM with SOI. Models were compared by receiver-operator characteristic (ROC) curve, area under the ROC curve (AUC), and Brier score. After exclusions, we analyzed 63,681 patient-visits. Overall in-hospital mortality was 1.3%. The median number of ICD-9-CM diagnosis codes was 6 (Q1-Q3 4-10). The median Charlson Comorbidity Index was 0 (Q1-Q3 0-2). When the model was applied to the validation set, the c-statistic for Charlson was 0.865, c-statistic for ROM was 0.975, and for ROM and SOI combined the c-statistic was 0.977. The scaled Brier score for Charlson was 0.044, Brier for ROM only was 0.230, and Brier for ROM and SOI was 0.257. The APR-DRG ROM or SOI subclasses are better predictors than the Charlson Comorbidity Index of in-hospital mortality among surgical patients.

Incidence and risk factors of anaesthesia-related perioperative cardiac arrest: A 6-year observational study from a tertiary care university hospital.

BACKGROUND: In recent decades, the incidences of anaesthesia-related perioperative mortality and adverse outcomes have decreased drastically. However, to date, data on perioperative cardiac arrest and risk factors of perioperative cardiac arrest from European countries are scarce. OBJECTIVES: To determine the incidences of perioperative cardiac arrest and rates of anaesthesia-related and anaesthesia-contributory cardiac arrest. Identification of pre-existing risk factors leading to perioperative cardiac arrest. DESIGN: Retrospective cohort study. SETTING: Department of Anaesthesiology and Intensive Care Medicine, University Hospital of Cologne, Germany. INTERVENTIONS: Perioperative critical incident reports between 2007 and 2012 were screened, and reports on cardiac arrest within 24 h postoperatively were identified. Cardiac arrests were classified as 'anaesthesia-related', 'anaesthesia-contributory' or 'anaesthesia-unrelated' by two reviewers independently. Univariate and multi-variate logistic regression analysis was used to identify risk factors associated with perioperative cardiac arrest. RESULTS: Analysis of 318 critical incidents from 169 500 anaesthetics revealed 99 perioperative cardiac arrests. This is an overall incidence of perioperative cardiac arrest of 5.8/10 000 anaesthetics [95% confidence interval (CI), 4.7 to 7.0]. The rate of anaesthesia-related cardiac arrest was 0.7/10 000 (95% CI, 0.3 to 1.1), and the rate of anaesthesia-contributory cardiac arrest was 1.7/10 000 (95% CI, 1.1 to 2.3). Most cardiac arrests related to anaesthesia were due to respiratory events. From the multi-variate analysis, American Society of Anesthesiologists physical status grade at least 3 [P = 0.007, odds ratio (OR) 2.59 (95% CI, 1.29 to 5.19)], emergency surgery [P < 0.001, OR 4.00 (95% CI, 2.15 to 7.54)] and pre-existing cardiomyopathy [P < 0.001, OR 17.48 (95% CI, 6.18 to 51.51)] emerged as predictors of cardiac arrest. CONCLUSION: These first available European data on perioperative cardiac arrest from a large unselected cohort indicate that the overall perioperative incidence of cardiac arrest at our institution was slightly lower than published in the literature, whereas rates of anaesthesia-related and anaesthesia-contributory cardiac arrest were comparable. Most cardiac arrests related to anaesthesia were due to respiratory events. American Society of Anesthesiologists physical status grade at least 3, emergency surgery and pre-existing cardiomyopathy appear to be relevant risk factors for cardiac arrest.

Select early type IA endoleaks after endovascular aneurysm repair will resolve without secondary intervention.

OBJECTIVE: Although it is traditionally considered ominous, the natural history of early proximal attachment site endoleaks (IA) after endovascular aneurysm repair (EVAR) is not well known. Our aim was to identify risk factors for persistent type IA endoleaks and to determine their effect on long-term outcomes after EVAR. METHODS: All patients who underwent infrarenal EVAR at a single institution between 1998 and 2015 were identified. Preoperative axial imaging and intraoperative arteriograms were reviewed, and those patients with a type IA endoleak were further studied. Aneurysm features were characterized by two reviewers and were studied for predictors of persistent endoleaks at the conclusion of the case. Patient records and the Social Security Death Index were used to record 1-year and overall survival. RESULTS: We identified 1484 EVARs, 122 (8%) of which were complicated by a type IA endoleak on arteriography after graft deployment, with a median follow-up of 4 years. The majority of patients underwent additional ballooning of the proximal site (52 [43%]) or placement of an aortic cuff (47 [39%]); 30 patients (25%) received a Palmaz stent, and four patients were treated with coils or anchors. At case end, only 43 (35%) of the type IA endoleaks remained; at 1 month, only 16 endoleaks persisted (13%), and only six persisted at 1 year (6%). In multivariable analysis, the only independent predictor of persistence of type IA endoleak at the conclusion of the case was the presence of extensive neck calcifications (odds ratio [OR], 9.9; 95% confidence interval [CI], 1.4-67.9; P = .02). Thirteen patients (11%) underwent reintervention for type IA endoleaks, with a time frame ranging from 3 days postoperatively to 11 years. There were three patients (2.4%) who experienced aneurysm rupture. Postoperative type IA endoleak was associated with lower survival at 1 year (79% vs 91%; relative risk, 2.5; 95% CI, 1.1-5.4; P = .02), but it did not affect long-term survival (log-rank, P = .45). Both an increase in aneurysm sac size and failure of the endoleak to resolve by case end were independent predictors of a need for reintervention (growth: OR, 8.3; 95% CI, 2.2-31.6; P < .01; persistent endoleak: OR, 7.6; 95% CI, 1.8-31.5; P < .01). A persistent type IA endoleak was not independently associated with an increase in sac size on surveillance imaging (P = .28). CONCLUSIONS: Aneurysm rupture secondary to persistent type IA endoleak is rare, and most will resolve within 1 year. Extensive neck calcification is the only independent predictor of persistent type IA endoleak, and an increase in sac size warrants reintervention. These data suggest that select early persistent type IA endoleaks can be safely observed.

Comparison of low density and high density pedicle screw instrumentation in Lenke 1 adolescent idiopathic scoliosis.

BACKGROUND: The correlation between implant density and deformity correction has not yet led to a precise conclusion in adolescent idiopathic scoliosis (AIS). The aim of this study was to evaluate the effects of low density (LD) and high density (HD) pedicle screw instrumentation in terms of the clinical, radiological and Scoliosis Research Society (SRS)-22 outcomes in Lenke 1 AIS. METHODS: We retrospectively reviewed 62 consecutive Lenke 1 AIS patients who underwent posterior spinal arthrodesis using all-pedicle screw instrumentation with a minimum follow-up of 24 months. The implant density was defined as the number of screws per spinal level fused. Patients were then divided into two groups according to the average implant density for the entire study. The LD group (n = 28) had fewer than 1.61 screws per level, while the HD group (n = 34) had more than 1.61 screws per level. The radiographs were analysed preoperatively, postoperatively and at final follow-up. The perioperative and SRS-22 outcomes were also assessed. Independent sample t tests were used between the two groups. RESULTS: Comparisons between the two groups showed no significant differences in the correction of the main thoracic curve and thoracic kyphosis, blood transfusion, hospital stay, and SRS-22 scores. Compared with the HD group, there was a decreased operating time (278.4 vs. 331.0 min, p = 0.004) and decreased blood loss (823.6 vs. 1010.9 ml, p = 0.048), pedicle screws needed (15.1 vs. 19.6, p < 0.001), and implant costs ($10,191.0 vs. $13,577.3, p = 0.003) in the LD group. CONCLUSIONS: Both low density and high density pedicle screw instrumentation achieved satisfactory deformity correction in Lenke 1 AIS patients. However, the operating time and blood loss were reduced, and the implant costs were decreased with the use of low screw density constructs.

Significant reduction of antibiotic consumption and patients' costs after an action plan in China, 2010-2014.

INTRODUCTION: On July 1, 2011, the Chinese government launched a national Action Plan for antibiotic stewardship targeting antibiotic misuse in public hospitals. The aim of this study was to evaluate the impacts of the Action Plan in terms of frequency and intensity of antibiotic utilization and patients costs in public general hospitals. METHODS: Administrative pharmacy data from July 2010 to June 2014 were sampled from 65 public general hospitals and divided into three segments: (1) July 2010 to June 2011 as the preparation period; (2) July 2011 to June 2012 as the intervention period; and (3) July 2012 to June 2014 as the assessment period. The outcome measures included (1) antibiotic prescribing rates; (2) intensity of antibiotic consumption; (3) patients costs; and (4) duration of peri-operative antibiotic treatment in clean surgeries of thyroidectomy, breast, hernia, and orthopedic procedures. Longitudinal and cross-sectional analyses were conducted. RESULTS: Longitudinal analyses showed significant trend changes in the frequency and intensity of antibiotic consumption, the patients' costs on antibiotics, and the duration of antibiotic treatment received by surgical patients undergoing the 4 clean procedures during the intervention period. Cross-sectional analyses showed that the antibiotic prescribing rates were reduced to 35.3% and 12.9% in inpatient and outpatient settings, that the intensity of antibiotic consumption was reduced to 35.9 DDD/100 bed-days, that patients' costs on antibiotics were reduced significantly, and that the duration of peri-operative antibiotic treatment received by surgical patients undergoing the 4 types of clean procedures decreased to less than 24 hour during the assessment period. CONCLUSION: The Action Plan, as a combination of managerial and professional strategies, was effective in reducing the frequency and intensity of antibiotic consumption, patients' costs on antibiotics, and the duration of peri-operative antibiotic treatment in the 4 clean surgeries.

Anesthesia-related critical incidents in the perioperative period in children; a proposal for an anesthesia-related reporting system for critical incidents in children.

BACKGROUND: The incidence, type and severity of anesthesia-related critical incidents during the perioperative phase has been investigated less in children than in adults. AIM: The aim of the study was to identify and analyze anesthesia-related critical incidents in children to identify areas to improve current clinical practice, and to propose a specialized anesthesia-related critical incidence registration for children. METHOD: All reported pediatric anesthesia-related critical incidents reported on a voluntary reporting based on a 20-item complication list of the Dutch Society of Anesthesiology between January 2007 and August 2013 were analyzed. An anesthesia-related critical incident was defined as 'any incident that affected, or could have affected, the safety of the patient while under the care of an anesthetist'. As the 20-item complications list was too crude for detailed analyses, all critical incidents were reclassified into the more detailed German classification lists with the adjustment of specific items for children (in total 10 categories with 101 different subcategories). RESULTS: During the 6-year period, a total of 1214 critical incidents were reported out of 35 190 anesthetics (cardiac and noncardiac anesthesia cases). The most frequently reported incidents (46.5%) were related to the respiratory system. Infants <1 year, children with ASA physical status III and IV, and emergency procedures had a higher rate of adverse incidents. CONCLUSION: Respiratory events were the most reported commonly critical incidents in children. Both the Dutch and German existing lists of critical incident definitions appeared not to be sufficient for accurate classification in children. The present list can be used for a new registration system for critical incidents in pediatric anesthesia.

Comparison of pediatric perioperative risk assessment by ASA physical status and by NARCO-SS (neurological, airway, respiratory, cardiovascular, other-surgical severity) scores.

BACKGROUND: ASA-PS is a widely used perioperative health assessment method, but with poor reproducibility. A novel objective, pediatric-specific risk classification system based on Neurological, Airway, Respiratory, Cardiovascular, Other categories and Surgical Severity (NARCO-SS) has been validated in only one US center. OBJECTIVE: Independent external validation of the NARCO-SS and comparison with the ASA-PS in predicting perioperative outcomes. METHODS: Preoperative ASA-PS and NARCO-SS scores were assigned to 387 children by pediatric anesthesia consultants at a tertiary care center in India and predefined perioperative adverse events and escalation of care recorded. Spearman's correlations determined the relationship between outcomes and scores and kappa statistics for interobserver reliability. The predictive performance of the ASA-PS and NARCO-SS was evaluated by the area under the receiver operating characteristics curves (AUC-ROC) for discrimination and Pearson's chi-square for calibration. RESULTS: NARCO-SS and ASA scores had significant Spearman's correlation coefficients with perioperative outcomes and moderate interobserver reliability. The NARCO-SS showed greater discrimination than the ASA-PS (AUC-ROC 0.778 vs 0.710 for escalation of care and 0.822 vs 0.724 for adverse events, P < 0.01). However, both scores had poor calibration (Pearson's chi-square, P < 0.0001). Individual NARCO-SS categories for neurological and airway lacked statistically significant Spearman's correlations. CONCLUSIONS: NARCO-SS is a valid risk stratification tool that is better than the ASA-PS in discriminating children with adverse perioperative outcomes. The poor calibration of both scores suggests neither can reliably predict perioperative outcomes in individual patients. Modification of neurological and airway categories may improve the predictive accuracy of the NARCO-SS.

Novel surgical performance evaluation approximates Standardized Incidence Ratio with high accuracy at simple means.

BACKGROUND: Excess adverse events may be attributable to poor surgical performance but also to case-mix, which is controlled through the Standardized Incidence Ratio (SIR). SIR calculations can be complicated, resource consuming, and unfeasible in some settings. This article suggests a novel method for SIR approximation. METHODS: In order to evaluate a potential SIR surrogate measure we predefined acceptance criteria. We developed a new measure - Approximate Risk Index (ARI). "Number Needed for Event" (NNE) is the theoretical number of patients needed "to produce" one adverse event. ARI is defined as the quotient of the group of patients needed for no observed events Ge by total patients treated Ga. Our evaluation compared 2500 surgical units and over 3 million heterogeneous risk surgical patients that were induced through a computerized simulation. Surgical unit's data were computed for SIR and ARI to evaluate compliance with the predefined criteria. Approximation was evaluated by correlation analysis and performance prediction capability by Receiver Operating Characteristics (ROC) analysis. RESULTS: ARI strongly correlates with SIR (r(2) = 0.87, p < 0.05). ARI prediction of excessive risk revealed excellent ROC (Area Under the Curve > 0.9) 87% sensitivity and 91% specificity. DISCUSSION AND CONCLUSIONS: ARI provides good approximation of SIR and excellent prediction capability. ARI is simple and cost-effective as it requires thorough risk evaluation of only the adverse events patients. ARI can provide a crucial screening and performance evaluation quality control tool. The ARI method may suit other clinical and epidemiological settings where relatively small fraction of the entire population is affected.

Demographics and perioperative outcome in patients with depression and anxiety undergoing total joint arthroplasty: a population-based study.

BACKGROUND: Depression and anxiety are highly prevalent psychiatric disorders. However, little is known about their impact on outcomes in the perioperative setting. This study is intended to gain insight into epidemiology and effects on perioperative morbidity, mortality, length of hospital stay, discharge and cost. METHODS: We obtained the National Inpatient Sample from the Hospital Cost and Utilization Project for each year between 2000 and 2008. Entries indicating the performance of primary total hip and knee arthroplasty were identified and separated into four groups: (1) those with concomitant diagnosis of depression or (2) anxiety, (3) both, and (4) none of these diagnoses. The incidence of major complications, non-routine discharge, length, and cost of hospitalization were assessed. Regression analysis was performed to identify if psychiatric comorbidity was an independent risk factor for each outcome. RESULTS: We identified 1,212,493 patients undergoing arthroplasty between 2000 and 2008. The prevalence of depression and anxiety significantly increased over time. Patients with either condition had higher hospital charges, rates of non-routine discharges and comorbidity index. Depression or anxiety were associated with significantly decreased adjusted odds for in-hospital mortality (OR = 0.53, p = 0.0147; OR = 0.58, p = 0.0064). The risk of developing a major complication was slightly lower in patients with depression, anxiety or both (OR=0.95, p = 0.0738; OR = 0.95, p = 0.0259; OR = 0.94, p = 0.7349). CONCLUSIONS: Patients suffering from depression, anxiety, or both require more healthcare resources in a perioperative setting. However, lower short-term mortality in spite of higher comorbidity burden and without extensive changes in perioperative complication profile indicates better outcome for this group of patients.

[Comparative assessment of risk factors and hospital results in male and female patients underwent to coronary artery bypass surgery].

There are controversial data on relatively unfavorable effect of female gender on postoperative mortality of patients underwent to coronary artery bypass grafting (CABG). In order to assess risk factors and hospital outcomes after elective CABG we studied retrospectively data on patients who had undergone CABG in Sani Konuogly medical center (Gasiatep, Turkey) during the period from March 2002 to March 2010. For elimination of unfavorable effect of old age we included into analysis data from patients younger than 65 years. In accordance with study aim all patients (n=2692) were divided into two gender groups 1966 men (mean age 54,01 years) and 726 women (mean age 54.35 years). Diabetes (48.3 and 26.9%; p=0.0001), arterial hypertension (76.6 and 28.4%; p=0.00001), and obesity (50 42%; p=0.03) were more frequent among women while smoking (44.5 and 10.3%; p=0.0001), hyperlipidemia (37.6 and 21.5%; p=0.0002), and history of myocardial infarction (31.3 and 17.3%; p=0.06) were more often registered among men. Mortality was insignificantly higher in women (1.6 and 0.9%; p=0.06). Perioperative Q-wave myocardial infarction was more frequent among men than among women (1.5 and 0.4% respectively; p=0.04). It is necessary to conduct prospective well controlled study for exclusion of gender influences on perioperative outcomes in patients subjected to CABG .

Errors and near misses in digestive endoscopy units.

BACKGROUND: Not much is known about errors and near misses in digestive endoscopy. AIMS: To verify whether an incident report, with certain facilitating features, gives useful information about unintended events, only excluding errors in medical diagnosis. METHOD: Nine endoscopy units took part in this cross sectional, prospective, multicentre study which lasted for two weeks. Members of the staff were required to report any unintended, potentially dangerous event observed during the daily work. A form was provided with a list of "reminders" and facilitators were appointed to help. The main outcome measurements were type of event, causes, corrective interventions, stage of occurrence in the workflow and qualification of the reporters. RESULTS: A total of 232 errors were reported (two were not related to endoscopy). The remaining 230 amount to 10.3% of 2239 procedures; 66 (29%) were considered errors with consequences, 164 (71%) "near misses". There were 150 pre-operative errors (65%), 22 operative (10%) and 58 post-operative (25%). Corrective interventions were provided for 60 cases of errors and 119 near misses. Most of the events were reported by the nurses (106 out of 232, 46%). CONCLUSIONS: Short-term incident reporting focusing on near misses, using forms with lists of "reminders", and the help of a facilitator, can give useful information on errors and near misses in digestive endoscopy.

A comparison of ambulatory perioperative times in hospitals and freestanding centers.

BACKGROUND: The volume of surgical procedures performed in ambulatory surgical centers has increased rapidly. METHODS: Ambulatory surgical visits of Medicare beneficiaries were compared for hospital-based and freestanding ambulatory surgical centers (ASCs). The main outcomes were time in surgery, time in operating room, time in postoperative care, and total perioperative time. RESULTS: The mean total perioperative time for all procedures examined was 39% shorter in freestanding ASCs then in hospital-based ASCs (83 vs 135 min; P < .01); surgery time was 37% shorter (19 vs 30 min; P < .01), operating room time was 37% shorter (34 vs 54 min; P < .01), and postoperative time was 35% shorter (48 vs 74 min; P < .01). CONCLUSIONS: Perioperative times were significantly shorter in freestanding ASCs than in hospital-based ASCs. It is unclear how much of the difference was the result of efficiency versus patient selection.

Desire for perioperative information and parental ethnicity.

OBJECTIVES: To examine the role of ethnicity, language, and socioeconomic variables in parental desire for information regarding children's surgery. AIM: To compare anesthetic and surgical information desired between English- and Spanish-speaking White and Hispanic mothers of children undergoing outpatient surgery. BACKGROUND: Parents report wanting to receive detailed information regarding children's preoperative care; however, variables such as parent ethnicity and language spoken have not been accounted for in understanding desire for information. METHODS/MATERIALS: One hundred and eighty-one mothers of children undergoing outpatient surgery, elective surgery, and general anesthesia were recruited and categorized into one of three groups: English-speaking White (ESW, n=79), English-speaking Hispanic (ESH, n = 63), and Spanish-speaking Hispanic (SSH, n = 39). In addition to providing demographic questionnaire, mothers completed the Parental Desire for Information (PDI) questionnaire, a 14-item measure of surgery and anesthesia-related statements. RESULTS: Overall, mothers desired receiving information about the majority of the items on the PDI. As compared to ESW mothers, SSH mothers and ESH mothers were overrepresented in the 'have a right to know' response option, with significant differences existing in items concerning alternative methods of anesthesia, details of needles used, and location of PACU and OR. CONCLUSIONS: Anesthesiologists should tailor the provision of preoperative information based on ethnicity and language of mothers involved. Ethnic and language differences shown in this study may exist in other populations as well.
