Small tunneled central venous catheters as an alternative to a standard hemodialysis catheter in neonatal patients

Background/PurposeContinuous renal replacement therapy (CRRT) is difficult in neonates for several reasons, including problems with catheter placement and maintenance. We sought to compare outcomes between standard hemodialysis catheters (HDC) and 6Fr-tunneled central venous catheters (TC-6Fr).MethodsWe evaluated neonates who received CRRT from December 2013 – January 2018. All patients received CRRT with the Aquadex (Baxter Corporation, Minneapolis, Minnesota) circuit. Data regarding patient demographics, CRRT indication, catheter days, reason for removal, and catheter-specific complications were analyzed.ResultsForty-six catheters were placed in 26 neonates; nine of these were 6Fr-tunneled catheters. The median age and mean weight at CRRT initiation was 9.5 days (IQR 4–31) and 3.5 kg (+/- 0.6 kg), respectively. TC-6Fr lasted longer (median of 28 days vs 10 days, p = 0.02), required fewer revisions (0 vs 0.16/10 catheter days) and were less commonly removed due to bleeding complications (0% vs 10.8%), occlusion (11.1% vs 18.9%), or malposition (0% vs 8.1%); none of these differences were statistically significant. TC-6Fr were associated with higher infection rates (33.3% vs 0%, p = 0.01) than HDC.ConclusionsTC-6Fr use resulted in less need for catheter revisions and provided longer-lasting vascular access, which may influence infection rates. This catheter provides neonates in need of CRRT more reliable vascular access.Level of evidence: III.     

Pediatric arterial femoral cannulations for extracorporeal membrane oxygenation: Does size really matter?

Background: No studies exist comparing various femoral artery cannula sizes in children on ECMO. We hypothesize that smaller arterial cannulas provide adequate flow in children while decreasing vascular complications.Methods: We performed a retrospective review of the ELSO database from 2012–2017. We included children undergoing femoral venoarterial ECMO between ages 12 and 18 years and weighing more than 30 kg. Arterial cannula sizes were grouped as: 15-16Fr, 17–18Fr, 19–20Fr and ≥21Fr. Arterial pump flow, bleeding complications, limb ischemia, and mechanical complications were compared by cannula size. Distal perfusion catheter and percutaneous placement were also compared for complications.Results: A total of 429 patients were included with 28.2% 15–16Fr, 32.2% 17–18Fr, 22.8% 19–20Fr, and 16.8% ≥ 21Fr arterial femoral cannulas. Median age was lower in the 15–16Fr group compared to the largest cannula group (14.7 years vs 15.5 years, p < 0.01). The overall mean arterial flow was 57.4 +/- 17.0 mL/kg/min with no difference in mean arterial flow rates among the cannula size groups (p = 0.85). There were no significant differences in all complications, bleeding or mechanical complications by arterial cannula size group. However, there was an increased risk of limb ischemia in the ≥21Fr group compared to the 15–16Fr group (OR 4.38, 95% CI 1.24–15.43; p = 0.02). Distal perfusion catheter was shown to increase the risk of mechanical complications (OR 1.78; 95% CI 1.03–3.07; p = 0.04) but did not make a statistically significant difference in limb ischemia (OR 0.37; 95% CI 0.12–1.11; p = 0.07).Conclusion: Review of the ELSO database demonstrates that the use of larger arterial cannulas compared to 15-16Fr cannulas are not needed to achieve similar pump flows for hemodynamic support but the largest cannula sizes may increase the risk of ischemic complications.     

The effect of aortic stenosis on elderly hip fracture outcomes: A case control study

IntroductionAortic stenosis (AS) is an established predictor of perioperative complications following both cardiac and non-cardiac surgery. The purpose of this study was to evaluate the risk of mortality and perioperative complications among surgically treated hip fractures in elderly patients with moderate or severe AS compared to those without AS (negative controls).Materials and methodsA retrospective case-controlled review (1:2) of elderly (≥65 years) surgically treated hip fractures from 2011 to 2015 with moderate/severe AS (according to American Heart Association criteria) was conducted. Postoperative complication rates, 30 days and 1 year mortality were reviewed.ResultsModerate/severe AS was identified in 65 hip fracture cases and compared to 129 negative controls. AS cases were significantly older with higher rates of coronary artery disease and atrial fibrillation (p < 0.05). Rates of any 30-day perioperative complication (74% vs. 37%, p < 0.001) and severe non-cardiac 30-day perioperative complication (52% vs. 26%, p = 0.002) were significantly higher among AS cases compared to controls. Kaplan Meier estimates of 30-day mortality (14.7% vs. 4.2%, p < 0.001) and 1-year mortality (46.8% vs. 14.1%, p < 0.001) were significantly higher in AS cases compared to controls. Multivariate analysis of severe 30-day postoperative complications identified moderate/severe AS (OR 4.02, p = 0.001), pulmonary disease (OR 7.36, p = 0.002) and renal disease (OR 3.27, p = 0.04) as independent predictors. Moderate/severe AS (OR 3.38, p = 0.03), atrial fibrillation (OR 3.73, p = 0.03) and renal disease (OR 4.44, p = 0.02) were independent predictors of 30-day mortality. Moderate/severe AS (OR 5.79, p < 0.001) and renal disease (OR 3.39, p = 0.02) were independent predictors of 1-year mortality.ConclusionAortic stenosis is associated with a significantly increased risk of perioperative complications, 30-day mortality and 1-year mortality in elderly patients undergoing surgical treatment of hip fractures.     

Risk profile of subcutaneous port placement in small children

Background/purposeLong-term central venous access is a safe and common procedure in children. However, complications with devices are a reality. Smaller children are thought to have a higher rate of complication after port placement, and some surgeons avoid placing ports with an arbitrary weight cutoff out of concern for surgical site morbidity.MethodsWe performed a multi-institutional retrospective review of 500 patients less than 5 years of age undergoing port placement at three large volume children's hospitals from 2014 to 2018. Patients were divided by weight greater than or less than 10 kg at the time of insertion. Statistical analysis was performed to evaluate for differences in outcomes between the two groups.ResultsThe majority of ports were placed for chemotherapy access (71.8%). Other indications included long-term infusions (18.8%) and difficult chronic IV access (9.4%). Of the 500 charts reviewed, 110 (22%) experienced some documented complication (28.9% < 10 kg, 20.6% > 10 kg, p = 0.096). There were no differences between the two groups in terms of the type or timing of complications. Overall, 16.3% of ports required removal prior to the end of therapy owing to a complication. Complication rate per day with the port in place was not different between the two groups (< 10 kg: 0.68 complications/1000 port-days vs > 10 kg 0.44 complications/1000 port-days, p = 0.068).ConclusionWeight less than 10 kg was not associated with a significantly higher incidence of any type of port complication in our cohort. This suggests that concern for complications should not exclude children less than 10 kg from port placement.Type of studyMulti-institutional retrospective review.Level of evidenceLevel III.     

Technical factors and outcomes in pediatric central venous port placement

Purpose While central venous port placement is common, there remains variation in placement technique and rates of technical complications. The aim of this study was to assess variability in techniques and identify predictors of complications for children undergoing port placement.Methods We retrospectively reviewed all 331 patients who underwent venous port placement at a single tertiary children's hospital from May 2018 to June 2020. The primary outcome was early revision or replacement (R/R) for complications occurring within 30 days. Secondary outcomes included radiation exposure and rate of intraoperative conversion to a secondary site.Results The median age was 7 years (Interquartile Range 3–13 years) and the most common diagnoses were leukemia (30.2%), solid tumors (27.8%), and brain tumors (16.9%). Initial approach for port placement was ultrasound-guided internal jugular (IJV) in 255 (147 by surgery and 108 by interventional radiology [IR]) and landmark subclavian vein (SCV) in 76 (all by surgery). Early R/R occurred in 5.1%, including 9.0% of patients with leukemia but 1.1% with solid tumors. Individual proceduralist volume ranged from 2 to 98 cases and was inversely correlated with early R/R (r = -0.12, p = 0.30). In univariate analysis, ports placed by IR had an increased rate of early R/R (9.3%, n = 10) compared to those placed by surgery (3.2%, n = 7, p = 0.036) but this was not significant in multivariable regression controlling for diagnosis and age (Hazard Ratio 2.04; p = 0.19). Mean fluoroscopy time was significantly longer for ports placed by IR (59.9 s) compared to those placed by surgery (15.1 s, p < 0.001). Initial SCV access was associated with an increased (14.5 vs 0.4%) rate of conversion to a secondary site.Conclusions Though venous port placement is a largely safe procedure in children, a substantial minority of patients, particularly those with leukemia, require early R/R. Proceduralist volume and training may influence early R/R, fluoroscopy exposure, and anatomic site preferences.     

Delayed versus early repair of inguinal hernia in preterm infants: A systematic review and meta-analysis

ObjectivesTo evaluate the clinical outcomes of herniotomy in preterm infants undergoing early versus delayed repair, the risk factors for complications, and to identify best timing of surgery.MethodsMedline, Embase and Central databases were searched from inception until 25 Jan 2021 to identify publications comparing the timing of neonatal inguinal hernia repair between early intervention (before discharge from first hospitalization) and delayed (after first hospitalisation discharge) intervention. Inclusion criteria was preterm infants diagnosed with inguinal hernia during neonatal intensive care unit admission. Results were analyzed using fixed and random effects meta-analysis (RevManv5.4).ResultsOut of 721 articles found, six studies were included in the meta-analysis. Patients in the early group had lower odds of developing incarceration [odds ratio (OR) 0.43, 95% confidence interval (CI) 0.34–0.55, I² = 0%, p < 0.001]; but higher risk of post-operative respiratory complications (OR 4.36, 95% CI 2.13–8.94, I² = 40%, p < 0.001). No significant differences were reported in recurrence rate (OR 3.10, 95% CI 0.90–10.64, I² = 0%, p = 0.07) and surgical complication rate (OR 0.94, 95% CI 0.18–4.83, I² = 0%, p = 0.94) between early and delayed groups.ConclusionWhile early inguinal hernia repair in preterm infants reduces the risk of incarceration, it increases the risk of post-operative respiratory complications compared to delayed repair. Surgeons should discuss the risks and benefits of delaying inguinal hernia repair with the caregivers to make an informed decision best suited to the patient physiology and circumstances.Level of evidenceTreatment study, level 3.     

The effect of standardized discharge instructions after gastrostomy tube placement on postoperative hospital utilization

Background/PurposeGastrostomy tube (GT) placement is a common pediatric procedure with high postoperative resource utilization. We aimed to determine if standardized discharge instructions (SDI) reduced healthcare utilization rates.MethodsWe performed a retrospective cohort study comparing postoperative hospital utilization of patients who underwent initial GT placement pre- and post-SDI protocol implementation from 2014–2019. Statistical analyses included Chi-square tests, multivariable adjusted logistic regression, adjusted Cox proportion hazard regression, and adjusted Poisson regression models when appropriate.Results197 patients were included, 102 (51.8%) before and 95 (48.2%) after protocol implementation. On primary analysis, SDI patients did not have significantly different total postoperative hospital utilization events at 30-days (48.0% vs. 38.9%, p = 0.25). On secondary analysis, SDI patients had lower rates of ED (8.4% vs. 19.6%, p = 0.026) and office visits (11.6% vs. 25.5%, p = 0.017) at 30-days. Non-SDIs patients had greater odds of ED visits (OR2.7, 95%CI 1.3–5.9, p = 0.01), office visits (OR3.7, 95%CI 1.7-8.1, p = 0.001) and phone calls (OR2.6, 95%CI 1.2–5.7, p = 0.016) at 1-year. The adjusted hazard ratio was 2.0 (95%CI 1.4–3.0, p < 0.001). Incident rate ratio were 1.8 (95%CI 1.2–2.5, p = 0.002) at 30-days and 1.9 (95%CI 1.5–2.4, p < 0.001) at 1-year post-discharge.ConclusionsSDIs post-GT placement may reduce multiple aspects of postoperative hospital utilization.     

Reduced complication rate after implementation of a detailed treatment protocol for percutaneous endoscopic gastrostomy with T-fastener fixation in pediatric patients: A prospective study

Background/aimsPercutaneous endoscopic gastrostomy with push technique (PEG-T) is increasingly used in pediatric patients. In a retrospective study of PEG-T (cohort 1) we reported frequent complications related to T-fasteners and tube dislodgment. The aim of this study was to assess complications after implementation of a strict treatment protocol, and to compare these with the previous retrospective study.Materials and methodsThe study is a prospective study of PEG-T placement performed between 2017 and 2020 (cohort 2) in pediatric patients (0–18 years). Complications were recorded during hospital stay, fourteen days and three months postoperatively, graded according to the Clavien-Dindo classification and categorized as early (<30 days) or late (>30 days).ResultsIn total 82 patients were included, of which 52 (60%) had neurologic impairments. Median age and weight were 2.0 years [6 months-18.1 years] and 13.4 kg [3.5–51.5 kg], respectively. There was a significant reduction in median operating time from 28 min [10–65 min] in cohort 1 to 15 min [6–35 min] in cohort 2 (p<0.001), number of patients with early tube dislodgement (cohort 1: 9 (10%) vs cohort 2: 1 (1%), p = 0.012), and number of patients with late migrated T-fasteners (cohort 1: 11 (13%) vs cohort 2: 1 (1%), p = 0.004).ConclusionWe experienced less migrated T-fasteners and tube dislodgment after implementation of strict treatment protocol.Level of evidenceTreatment study level III.     

Postoperative outcomes in older surgical patients with preoperative cognitive impairment: A systematic review and meta-analysis

Study objectiveTo determine the effect of cognitive impairment (CI) and dementia on adverse outcomes in older surgical patients.DesignA systematic review and meta-analysis of observational studies and randomized controlled trials (RCTs). Various databases were searched from their inception dates to March 8, 2021.SettingPreoperative assessment.PatientsOlder patients (≥ 60 years) undergoing non-cardiac surgery.MeasurementsOutcomes included postoperative delirium, mortality, discharge to assisted care, 30-day readmissions, postoperative complications, and length of hospital stay. Effect sizes were calculated as Odds Ratio (OR) and Mean Difference (MD) based on random effect model analysis. The quality of included studies was assessed using the Cochrane Risk Bias Tool for RCTs and Newcastle-Ottawa Scale for observational cohort studies.ResultsFifty-three studies (196,491 patients) were included. Preoperative CI was associated with a significant risk of delirium in older patients after non-cardiac surgery (25.1% vs. 10.3%; OR: 3.84; 95%CI: 2.35, 6.26; I²: 76%; p < 0.00001). Cognitive impairment (26.2% vs. 13.2%; OR: 2.28; 95%CI: 1.39, 3.74; I²: 73%; p = 0.001) and dementia (41.6% vs. 25.5%; OR: 1.96; 95%CI: 1.34, 2.88; I²: 99%; p = 0.0006) significantly increased risk for 1-year mortality. In patients with CI, there was an increased risk of discharge to assisted care (44.7% vs. 38.3%; OR 1.74; 95%CI: 1.05, 2.89, p = 0.03), 30-day readmissions (14.3% vs. 10.8%; OR: 1.36; 95%CI: 1.00, 1.84, p = 0.05), and postoperative complications (40.7% vs. 18.8%; OR: 1.85; 95%CI: 1.37, 2.49; p < 0.0001).ConclusionsPreoperative CI in older surgical patients significantly increases risk of delirium, 1-year mortality, discharge to assisted care, 30-day readmission, and postoperative complications. Dementia increases the risk of 1-year mortality. Cognitive screening in the preoperative assessment for older surgical patients may be helpful for risk stratification so that appropriate management can be implemented to mitigate adverse postoperative outcomes.     

Factors associated with in-hospital complications and long-term implications of these complications in elderly patients undergoing endovascular aneurysm repair

ObjectivePerioperative complications in elderly patients undergoing endovascular aneurysm repair (EVAR) occur frequently. Although perioperative mortality has been well-described in the elderly patient population, factors associated with in-hospital complications and their impact on long-term survival remain poorly characterized.MethodsWe identified all patients undergoing elective EVAR for infrarenal AAA within the Vascular Quality Initiative registry (2003-2018) and compared in-hospital complication rates between elderly (age ≥75) and nonelderly patients (<75). We used logistic regression to identify independent factors associated with in-hospital complications, whereas Kaplan-Meier analysis and Cox proportional hazards models were used to determine associations between complications and long-term survival. To assess the effect of complications on early and late survival, we stratified survival periods into the first 30 days after discharge, and between 1 and 6 months, 7 and 12 months, and 1 and 8 years after the index procedure. To investigate the implications of in-hospital morbidity on long-term outcomes, we estimated the adjusted population-attributable fractions of individual complications on both perioperative and long-term survival.ResultsWe identified 17,156 elderly patients and 19,922 nonelderly patients. Elderly patients experienced higher complication rates compared with nonelderly patients (17% vs 10%; P < .001). The factors with the strongest associations with morbidity in elderly patients were anemia (odds ratio [OR], 2.4; 95% confidence interval [CI], 2.2-2.6), female gender (OR, 1.9; 95% CI, 1.7-2.1), and large AAA diameter (OR, 1.7; 95% CI, 1.6-1.9). Patients with any in-hospital complication had lower unadjusted survival estimates than patients without complications at 1 year (83% vs 95%; P < .001), 5 years (66% vs 80%; P < .001), and 8 years (60% vs 72%; P < .001). After risk adjustment, in-hospital complications were independently associated with higher mortality, although the association attenuated over time (first month after discharge: hazard ratio [HR], 5.9; 95% CI, 3.9-9.1; 1-6 months after the procedure: HR, 2.1; 95% CI, 1.7-2.7; P < .001; 7-12 months after the procedure: HR, 1.5; 95% CI, 1.1-1.9; 1-8 years after the procedure: HR, 1.2; 95% CI, 1.01-1.3). Of all deaths occurring within 8 years after procedure, 9.5% were independently associated with in-hospital complications. Complications with the greatest impact on long-term mortality were renal dysfunction (2.4%), blood transfusion (3.4%), and reintubations (2.4%).ConclusionsElderly patients are at higher risk for in-hospital complications after EVAR. These in-hospital complications have a significant impact on both short- and long-term survival. To further improve the delivery of EVAR care nationally, quality improvement efforts should be focused on preventing postoperative morbidity in elderly patients, as well as refining out of hospital surveillance strategies for subjects who experience in-hospital complications to improve overall survival.     

Questioning Prophylactic Antibiotic Use for Pyloromyotomy: Analysis of the Pediatric Health Information System Database

BackgroundPyloromyotomy has a low rate of wound complications, yet antibiotic prophylaxis is still given. The Pediatric Health Information System (PHIS) database was queried to determine whether prophylactic antibiotics decreased wound complications.MethodsRecords for infants with pyloric stenosis between 2016 and 2021 were extracted from the PHIS database and analyzed for demographics, comorbid conditions, and complications within 30 days of pyloromyotomy. Logistic regression was used to evaluate the effect of antibiotic prophylaxis on complications.ResultsAmong 14,247 infants who underwent pyloromyotomy, 29.5% had antibiotic prophylaxis. These patients were more likely to have been admitted to the NICU and have chronic conditions and prematurity (p < 0.01). Antibiotic utilization varied among hospitals from 2.3 to 58.5%. Complication rates among those who received antibiotics was 1.64% versus 1.62% for those who did not. The odds for developing complications in those who received prophylaxis compared to those who did not was 1.10, (0.73, 1.41, 95%, p = 0.93) suggesting there is no effect of antibiotics on complication rates.ConclusionsThere was a wide variation among hospitals in the usage of prophylactic antibiotics for pyloromyotomy. There was no difference in complication rates whether or not patients received antibiotics. These results suggest antibiotic prophylaxis is unnecessary for pyloromyotomy.Level of EvidenceIII.     

Integration of a dedicated management protocol in the care of pediatric liver cancer: From specialized providers to complication reduction

IntroductionUp to a third of children undergoing partial hepatectomy for primary hepatic malignancies experience at least one perioperative complication, with a presumed deleterious effect on both short- and long-term outcomes. We implemented a multidisciplinary treatment protocol in the management of these patients in order to improve complication rates following partial hepatectomy.MethodsA retrospective chart review was completed for all patients < 18 years of age who underwent liver resection at our institution between 2002 and 2019 for primary hepatic cancer. Demographic, intraoperative, postoperative, pathologic, and outcome data were analyzed for perioperative complications using the CLASSIC and Clavien-Dindo (CD) scales, event-free survival (EFS) and overall survival (OS).ResultsA total of 73 patients were included in the analysis with 33 prior-to and 40 after dedicated provider protocol implementation. Perioperative complication rates decreased from 52% to 20% (p = 0.005) with major complications going from 18% to 10% (p = 0.31). On multivariable logistic regression, protocol implementation was associated with a reduction in any (OR 0.29 [95% CI 0.09 – 0.89]) but not major complications. On multivariate cox models, post protocol implementation was associated with improved event free survival (EFS) (HR 0.19 (0.036 – 0.195). Among patients with a diagnosis of hepatoblastoma (n = 62), the occurrence of a major perioperative complication was associated with a worse EFS (HR=5.45, p = 0.03) on multivariate analysis, however this did not translate into an impact on overall survival.ConclusionsOur results demonstrate that, for children with primary liver malignancies, a dedication of patients to high-volume surgeons can improve rates of complications of liver resections and may improve the oncological outcome of hepatoblastoma.     

Association of pre-admission opioid abuse and/or dependence on major complications in traumatic brain injury (TBI) patients

SettingIn the last few decades, an opioid related health crisis has been a challenging problem in many countries around the world, especially the United States. Better understanding of the association of pre-admission opioid abuse and/or dependence (POAD) on specific major complications in traumatic brain injury (TBI) patients can aid the medical team in improving patient care management and outcomes.Study objectiveOur goal is to assess and quantify the risk of POAD on in-hospital mortality and major complications in TBI patients.DesignWe conducted a retrospective study and used the National Inpatient Sample (NIS) database from 2004 to 2015 to investigate the impact of POAD on in-hospital mortality and major complications in TBI patients. We utilized propensity score matching and conditional logistic regression models, adjusted with injury severity score (ISS) and comorbidities, to obtain the adjusted odds ratios (OR).Main resultsPOAD TBI patients had lower risks of in-hospital mortality (OR 0.58; p < 0.001) and acute myocardial infarction (OR 0.53; p = 0.045), while a higher risk of respiratory (OR 1.59; p < 0.001) and neurologic complications (OR 2.54; p < 0.001), compared to non-POAD TBI patients. Additionally, POAD patients were significantly more likely to have sepsis (OR 2.16, p < 0.001), malnutrition (OR 1.56, p < 0.001), delirium (OR 2.81, p < 0.001), respiratory failure (OR 1.79, p < 0.001), and acute renal failure (OR 1.83, p < 0.001). POAD TBI patients had shorter length of hospital stay compared to non-POAD TBI patients (mean 8.0 vs 9.2 days, p < 0.001).ConclusionsPOAD TBI patients have a lower in-hospital mortality, shorter duration of hospitalization and a lower risk of acute myocardial infarction, while they are more likely to have respiratory failure, delirium, sepsis, malnutrition, and acute renal failure compared to TBI patients without POAD. Prospective study is warranted to further confirm these findings.     

Effect of COVID-19 on pediatric appendicitis presentations and complications

PurposeAppendicitis is the most common surgical emergency in children. This study aims to examine how the COVID-19 pandemic affected pediatric patients with acute appendicitis with regards to presentation and complications.MethodsAfter obtaining ethics approval, we performed a chart review of pediatric patients admitted with a diagnosis of appendicitis from March 1, 2019 to June 30, 2019 and March 1, 2020 to June 30, 2020. Data collection included a post-operative period of 30 days. The primary outcome of interest was complication rates post-appendectomy. Secondary outcomes included time to presentation, symptoms, time to surgery, and rate of perforation.ResultsOverall, 205 patients were included with 115 in the pre-pandemic group and 90 in the pandemic group. There was no significant difference in complication rates (16% pre-pandemic vs. 13.3% pandemic). In the pandemic group, time from symptom onset to presentation was significantly longer (1.87 days vs. 2.42 days, p = 0.01), more patients presented with emesis (70% vs. 55%, p<0.05), more patients had perforated appendicitis (47% vs. 32%, p<0.05), more patients were likely to be tachycardic (46% vs. 32%, p = 0.05)  and waited less time for surgery (5.75 h vs. 4.15 h, p = 0.05) which both approached significance.ConclusionSignificant delays in pediatric appendicitis presentation, and higher rates of tachycardia and perforation were seen during the pandemic. This did not result in increased complication rates but could suggest pandemic patients were more ill than their pre-pandemic counterparts.     

Delayed extubation in spine surgery is associated with increased postoperative complications and hospital episode-based resource utilization

Study objectiveTo elucidate the association between delayed extubation, postoperative complications, and episode-based resource utilization.DesignRetrospective Propensity-Matched Cohort Study.SettingSingle Large Academic Medical Center.PatientsThe computerized anesthetic records of 17,223 patients undergoing spine surgery from January 2006 through November 2016 were reviewed for this study. The records of 11,421 patients met inclusion criteria for final analysis, with 527 subjects who had delayed extubation following their procedure.InterventionsDelayed extubation, defined as patients not extubated prior to leaving the operating room.MeasurementsComputerized anesthetic records of spine surgery patients were analyzed retrospectively. Corresponding Medicare Severity Diagnosis Related Group numbers (MS-DRGs) were then identified, as well as associated lengths of stay and costs of care. We compared hospital-acquired International Classification of Diseases-9 (ICD-9) and ICD-10 postoperative complication codes linked to each record to assess differences in outcome.Main resultsIncreasing medical and surgical complexity is associated with delayed extubation. Using propensity score matching, delayed extubation was independently associated with a higher likelihood of any postoperative complication (Odds Ratio [OR]: 1.79; 95% Confidence Interval [CI]: 1.23–2.61); major complications (OR: 2.22; 95% CI: 1.31–3.76); prolonged length of hospital stay (Hazard Ratio [HR]: 0.82 (0.72, 0.95), p = 0.006); prolonged Intensive Care Unit (ICU) stay (HR: 0.68 (0.61, 0.76), p < 0.001); and were less likely to be discharged home (OR: 1.40 (1.02, 1.92), p = 0.036). Propensity score matching demonstrated that anesthesiologist handoff was not independently associated with any of the examined adverse outcomes.ConclusionsDelayed extubation after spine surgery was associated with a statistically significant increased incidence of postoperative complications as well as increased hospital episode-based resource utilization in the form of increased hospital length of stay, ICU length of stay, post-acute care at a facility, and higher cost of hospitalization. Although anesthesiologist handoff was associated with delayed extubation, it was not independently associated with postoperative complications when propensity score matching was applied.     

Primary contributors to gastrostomy tube placement in infants with Congenital Diaphragmatic Hernia

ObjectiveTo identify factors associated with gastrostomy tube (GT) placement in infants with congenital diaphragmatic hernia (CDH).MethodsRetrospective cohort study of 114 surviving infants with CDH at a single tertiary care neonatal intensive care unit from 2010–2019. Prenatal, perinatal and postnatal characteristics were compared between patients who were discharged home with and without a GT. Prenatal imaging was available for 50.9% of the cohort. Logistic regression was used to assess the association between GT placement and pertinent clinical factors. ROC curves were generated, and Youden's J statistic was used to determine optimal predictive cutoffs for continuous variables. Elastic net regularized regression was used to identify variables associated with GT placement in multivariable analysis.ResultsGT was placed in 43.9% of surviving infants with CDH. Prenatal variables predictive of GT placement were percent predicted lung volume (PPLV) <21%, total lung volume (TLV) <30 ml, lung-head ratio (LHR) <1.2 or observed to expected LHR (O/E LHR) <55%. Infants who required a GT were diagnosed earlier prenatally (23.6 ± 3.4 vs. 26.4 ± 5.6 weeks). Patients whose stomach was above the diaphragm on prenatal ultrasound (up) had a higher odds of GT placement compared to those with stomachs below the diaphragm (down) position by a factor of 2.9 (95% CI: 1.25, 7.1); p = 0.0154. Postnatally, infants with GT had lower Apgar scores at 1 and 5 min, longer lengths of stay and higher proportion of flap closures. Infants with a type C or D defect and extracorporeal membrane oxygenation (ECMO) were associated with increased odds of needing a GT. Postnatal association included being NPO for >12 days, need for transpyloric (TP) feeds for >10 days, >14 days to transition to a 30 min bolus feed, presence of gastro-esophageal reflux (GER), chronic lung disease and pulmonary hypertension. In multivariable analysis, duration of NPO, time to TP feeds, transition to 30 min bolus feeds remained significantly associated with GT placement after adjusting for severity of pulmonary hypertension (PH), GER diagnosis and sildenafil treatment.ConclusionIdentification of risk factors associated with need for long-term feeding access may improve timing of GT placement and prevent prolonged hospitalization related to feeding issues.Level of Evidence RatingLevel II (Retrospective Study)     

The Importance of Oral History: Does Dental Implant Placement or Caries One Year Before or After Primary Total Knee Arthroplasty Increase Medical Complications and Periprosthetic Joint Infections?

BackgroundConsensus regarding prior dental problems on the outcomes of total knee arthroplasty (TKA) patients is lacking. Therefore, our objectives were to determine the association of dental caries or dental implant placement in TKA patients on the following: (1) medical complications; (2) health care utilization (lengths of stay and readmissions); (3) implant-related complications; and (4) expenditures.MethodsA retrospective query was performed using an administrative claims database for 3 patient cohorts undergoing primary TKA from 2010 to 2020. Patients who had a history of dental caries or implant placement 1 year prior to TKA (n = 1,466) and 1 year after TKA (n = 1,127) were case-matched to patients who did not have a dental history by age and comorbidities. Outcomes included 90-day complications, health care utilization parameters, 2-year implant complications, and expenditures. Logistic regression models computed odds ratios (OR) of complications and readmissions. P values less than 0.005 were significant.ResultsPatients who had a dental implant placement prior to TKA had higher frequency of complications (20.05 versus 14.01%; OR: 1.53, P < .0001), including myocardial infarctions (2.52 versus 1.23%; OR: 2.08, P = .0002) and pneumonia (2.52 versus 1.24%; OR: 2.06, P = .0002). Lengths of stay (3.28 versus 2.98 days; P = .255), readmission rates (4.71 versus 4.28%; P = .470), and implant-related complications including periprosthetic joint infections (3.14 versus 2.63%; OR: 1.20, P = .279) were similar between patients lacking dental history. Expenditures were higher in patients who had a postoperative and preoperative dental history ($19,252 versus $19,363 versus 17,980; P < .001).ConclusionDental caries or implant placement may reflect overall worse medical condition resulting in more complications and higher costs after TKA. Dental history screening preoperatively may assist arthroplasty surgeons in minimizing complications.     

Risk factors for perioperative hypothermia and infectious outcomes in gastroschisis patients

IntroductionPrior data suggest that infants with gastroschisis are at high risk for hypothermia and infectious complications (ICs). This study evaluated the associations between perioperative hypothermia (PH) and ICs in gastroschisis using a multi-institutional cohort.MethodsRetrospective review of infants with gastroschisis who underwent abdominal closure from 2013–2017 was performed at 7 children's hospitals. Any-IC and surgical site infection (SSI) were stratified against the presence or absence of PH, and perioperative characteristics associated with PH and SSI were determined using multivariable logistic regression.ResultsOf 256 gastroschisis neonates, 42% developed PH, with 18% classified as mild hypothermia (35.5–35.9°C), 10.5% as moderate (35.0–35.4°C), and 13% severe (<35°C). There were 82 (32%) ICs with 50 (19.5%) being SSIs. No associations between PH and any-IC (p = 0.7) or SSI (p = 0.98) were found. Pulmonary comorbidities (odds ratio (OR)=3.76, 95%CI:1.42–10, p = 0.008) and primary closure (OR=0.21, 95%CI:0.12–0.39, p<0.001) were associated with PH, while silo placement (OR=2.62, 95%CI:1.1–6.3, p = 0.03) and prosthetic patch (OR=3.42, 95%CI:1.4–8.3, p = 0.007) were associated with SSI on multivariable logistic regression.ConclusionsPrimary abdominal closure and pulmonary comorbidities are associated with PH in gastroschisis, however PH was not associated with increased risk of ICs. Independent risk factors for SSI include silo placement and prosthetic patch closure.     

Quality of life,pain of prepectoral and subpectoral implant-based breast reconstruction with a discussion on cost: A systematic review and meta-analysis

IntroductionPrepectoral implant-based breast reconstruction (PIBR) has regained popularity, despite decades-long preference for subpectoral implant placement. This paper aims to compare patient-reported outcomes (PRO) between prepectoral and subpectoral approaches to implant-based breast reconstruction (IBBR). The primary PRO was with the BREAST-Q, and postoperative pain scores, while the secondary outcomes were complication rates.MethodsA comprehensive literature search of the PubMed library was performed. All studies on patients undergoing IBBR after mastectomy that compared prepectoral to subpectoral placement and PROM or postoperative pain were included.ResultsA total of 3789 unique studies of which 7 publications with 216 and 332 patients who received prepectoral and subpectoral implants, respectively, were included for meta-analysis.Patients with prepectoral implant placement had significantly higher satisfaction with the outcome (p = 0.03) and psychosocial well-being (p = 0.03) module scores. The pain was lower in patients with prepectoral implants on postoperative day 1 (p<0.01) and day 7 (p<0.01). The subgroup analysis of prepectoral breast implants showed that complete acellular dermal matrix coverage had lower rates of wound dehiscence (p<0.0001), but there were no significant differences in complications between one-stage and two-stage procedures.ConclusionOverall, patients with prepectoral implants reported higher BREAST-Q scores and lower postoperative pain and lower complications rates than patients with subpectoral implants. In appropriately selected patients, prepectoral implant placement with ADM coverage, be it the primary placement of an implant or placement of a tissue expander before definitive implant placement, should be the modality of choice in patients who choose IBBR. Further research should focus on patient selection, strategies to reduce cost and cost-benefit analysis of PIBR.     

Association between use of enhanced recovery after surgery protocols and postoperative complications in colorectal surgery in Europe: The EuroPOWER international observational study

Study objectiveAssess the relationship between the Enhanced Recovery After Surgery (ERAS®) pathway and routine care and 30-day postoperative outcomes.DesignProspective cohort study.SettingEuropean centers (185 hospitals) across 21 countries.PatientsA total of 2841 adult patients undergoing elective colorectal surgery. Each hospital had a 1-month recruitment period between October 2019 and September 2020.InterventionsRoutine perioperative care.MeasurementsTwenty-four components of the ERAS pathway were assessed in all patients regardless of whether they were treated in a formal ERAS pathway. A multivariable and multilevel logistic regression model was used to adjust for baseline risk factors, ERAS elements and country-based differences.ResultsA total of 1835 patients (65%) received perioperative care at a self-declared ERAS center, 474 (16.7%) developed moderate-to-severe postoperative complications, and 63 patients died (2.2%). There was no difference in the primary outcome between patients who were or were not treated in self-declared ERAS centers (17.1% vs. 16%; OR 1.00; 95%CI, 0.79–1.27; P = 0.986). Hospital stay was shorter among patients treated in self-declared ERAS centers (6 [5–9] vs. 8 [6–10] days; OR 0.82; 95%CI, 0.78–0.87; P < 0.001). Median adherence to 24 ERAS elements was 57% [48%–65%]. Adherence to ERAS-pathway quartiles (≥65% vs. <48%) suggested that patients with the highest adherence rates experienced a lower risk of moderate-to-severe complications (15.9% vs. 17.8%; OR 0.71; 95%CI, 0.53–0.96; P = 0.027), lower risk of death (0.3% vs. 2.9%; OR 0.10; 95%CI, 0.02–0.42; P = 0.002) and shorter hospital stay (6 [4–8] vs. 7 [5–10] days; OR 0.74; 95%CI, 0.69–0.79; P < 0.001).ConclusionsTreatment in a self-declared ERAS center does not improve outcome after colorectal surgery. Increased adherence to the ERAS pathway is associated with a significant reduction in overall postoperative complications, lower risk of moderate-to-severe complications, shorter length of hospital stay and lower 30-day mortality.
