Anesthetic management for transcatheter aortic valve replacement: A national anesthesia clinical outcomes registry analysis.

Background: General anesthesia has traditionally been used in transcatheter aortic valve replacement; however, there has been increasing interest and momentum in alternative anesthetic techniques. Aims: To perform a descriptive study of anesthetic management options in transcatheter aortic valve replacements in the United States, comparing trends in use of monitored anesthesia care versus general anesthesia. Settings and Design: Data evaluated from the American Society of Anesthesiologists' (ASA) Anesthesia Quality Institute's National Anesthesia Clinical Outcomes Registry. Materials and Methods: Multivariable logistic regression was used to identify predictors associated with use of monitored anesthesia care compared to general anesthesia. Results: The use of monitored anesthesia care has increased from 1.8% of cases in 2013 to 25.2% in 2017 (p = 0.0001). Patients were more likely ages 80+ (66% vs. 61%; p = 0.0001), male (54% vs. 52%; p = 0.0001), ASA physical status > III (86% vs. 80%; p = 0.0001), cared for in the Northeast (38% vs. 22%; p = 0.0001), and residents in zip codes with higher median income ($63,382 vs. $55,311; p = 0.0001). Multivariable analysis revealed each one-year increase in age, every 50 procedures performed annually at a practice, and being male were associated with 3% (p = 0.0001), 33% (p = 0.012), and 16% (p = 0.026) increased odds of monitored anesthesia care, respectively. Centers in the Northeast were more likely to use monitored anesthesia care (all p < 0.005). Patients who underwent approaches other than percutaneous femoral arterial were less likely to receive monitored anesthesia care (adjusted odds ratios all < 0.51; all p = 0.0001). Conclusion: Anesthetic type for transcatheter aortic valve replacements in the United States varies with age, sex, geography, volume of cases performed at a center, and procedural approach.

Comparing Consumer-Directed Hospital Rankings With STS Adult Cardiac Surgery Database Outcomes.

BACKGROUND: Public interest in stratifying hospital performance has led to the proliferation of commercial, consumer-oriented hospital rankings. In cardiac surgery, little is known about how these rankings correlate with clinical registry quality ratings. METHODS: The Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database was queried for isolated coronary artery bypass grafting or coronary artery bypass grafting/valve patients at hospitals among the top 100 U.S. News & World Report (USNWR) Cardiology & Heart Surgery rankings from 2016 to 2020. Hospitals were grouped into deciles by risk-adjusted observed/expected (O/E) ratios for morbidity and mortality using the STS 2018 risk models. Agreement between STS Adult Cardiac Surgery Database and USNWR ranked deciles was calculated by Bowker symmetry test. The association between each center's annual change in STS O/E ratio and change in USNWR ranking was modeled in repeated measures regression analysis. RESULTS: Inclusion criteria were met by 524 393 patients from 149 hospitals that ranked in USNWR top 100 at least once during the study period. There was no agreement between USNWR ranking and STS major morbidity and mortality O/E ratio (P > .50 for all years). Analysis of patients undergoing surgery at the 65 hospitals that were consistently ranked in the top 100 during the study period demonstrated no association between annual change in hospital ranking and change in O/E ratio (P all > .3). CONCLUSIONS: There was no agreement between annual USNWR hospital ranking and corresponding risk-adjusted STS morbidity or mortality. Furthermore, annual changes in USNWR rankings could not be accounted for using clinical outcomes. These findings suggest that factors unrelated to key surgical outcomes may be driving consumer-directed rankings.

The Society of Thoracic Surgeons 2021 Adult Cardiac Surgery Risk Models for Multiple Valve Operations.

BACKGROUND: The Society of Thoracic Surgeons (STS) Quality Measurement Task Force has developed risk models and composite performance measures for isolated coronary artery bypass grafting (CABG), isolated aortic valve replacement (AVR), isolated mitral valve replacement or repair (MVRR), AVR+CABG, and MVRR+CABG. To further enhance its portfolio of risk-adjusted performance metrics, STS has developed new risk models for multiple valve operations ± CABG procedures. METHODS: Using July 2011 to June 2019 STS Adult Cardiac Surgery Database data, risk models for AVR+MVRR (n = 31,968) and AVR+MVRR+CABG (n = 12,650) were developed with the following endpoints: Operative Mortality, major morbidity (any 1 or more of the following: cardiac reoperation, deep sternal wound infection/mediastinitis, stroke, prolonged ventilation, and renal failure), and combined mortality and/or major morbidity. Data were divided into development (July 2011 to June 2017; n = 35,109) and validation (July 2017 to June 2019; n = 9509) samples. Predictors were selected by assessing model performance and clinical face validity of full and progressively more parsimonious models. Performance of the resulting models was evaluated by assessing discrimination and calibration. RESULTS: C-statistics for the overall population of multiple valve ± CABG procedures were 0.7086, 0.6734, and 0.6840 for mortality, morbidity, and combined mortality and/or morbidity in the development sample, and 0.6953, 0.6561, and 0.6634 for the same outcomes, respectively, in the validation sample. CONCLUSIONS: New STS Adult Cardiac Surgery Database risk models have been developed for multiple valve ± CABG operations, and these models will be used in subsequent STS performance metrics.

Impact of ICD-9 to ICD-10 Coding Transition on Prevalence Trends in Neurology.

OBJECTIVE: To determine the effect of International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) to International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) coding transition on the point prevalence and longitudinal trends of 16 neurologic diagnoses. METHODS: We used 2014-2017 data from the National Inpatient Sample to identify hospitalizations with one of 16 common neurologic diagnoses. We used published ICD-9-CM codes to identify hospitalizations from January 1, 2014, to September 30, 2015, and used the Agency for Healthcare Research and Quality's MapIt tool to convert them to equivalent ICD-10-CM codes for October 1, 2015-December 31, 2017. We compared the prevalence of each diagnosis before vs after the ICD coding transition using logistic regression and used interrupted time series regression to model the longitudinal change in disease prevalence across time. RESULTS: The average monthly prevalence of subarachnoid hemorrhage was stable before the coding transition (average monthly increase of 4.32 admissions, 99.7% confidence interval [CI]: -8.38 to 17.01) but increased after the coding transition (average monthly increase of 24.32 admissions, 99.7% CI: 15.71-32.93). Otherwise, there were no significant differences in the longitudinal rate of change in disease prevalence over time between ICD-9-CM and ICD-10-CM. Six of 16 neurologic diagnoses (37.5%) experienced significant changes in cross-sectional prevalence during the coding transition, most notably for status epilepticus (odds ratio 0.30, 99.7% CI: 0.26-0.34). CONCLUSIONS: The transition from ICD-9-CM to ICD-10-CM coding affects prevalence estimates for status epilepticus and other neurologic disorders, a potential source of bias for future longitudinal neurologic studies. Studies should limit to 1 coding system or use interrupted time series models to adjust for changes in coding patterns until new neurology-specific ICD-9 to ICD-10 conversion maps can be developed.

Readmission After Lobectomy for Lung Cancer: Not All Complications Contribute Equally.

OBJECTIVE: The aim of this study was to identify independent predictors of hospital readmission for patients undergoing lobectomy for lung cancer. SUMMARY BACKGROUND DATA: Hospital readmission after lobectomy is associated with increased mortality. Greater than 80% of the variability associated with readmission after surgery is at the patient level. This underscores the importance of using a data source that includes detailed clinical information. METHODS: Using the Society of Thoracic Surgeons (STS) General Thoracic Surgery Database (GTSD), we conducted a retrospective cohort study of patients undergoing elective lobectomy for lung cancer. Three separate multivariable logistic regression models were generated: the first included preoperative variables, the second added intraoperative variables, and the third added postoperative variables. The c statistic was calculated for each model. RESULTS: There were 39,734 patients from 277 centers. The 30-day readmission rate was 8.2% (n = 3237). In the final model, postoperative complications had the greatest effect on readmission. Pulmonary embolus {odds ratio [OR] 12.34 [95% confidence interval (CI),7.94-19.18]} and empyema, [OR 11.66 (95% CI, 7.31-18.63)] were associated with the greatest odds of readmission, followed by pleural effusion [OR 7.52 (95% CI, 6.01-9.41)], pneumothorax [OR 5.08 (95% CI, 4.16-6.20)], central neurologic event [OR 3.67 (95% CI, 2.23-6.04)], pneumonia [OR 3.13 (95% CI, 2.43-4.05)], and myocardial infarction [OR 3.16 (95% CI, 1.71-5.82)]. The c statistic for the final model was 0.736. CONCLUSIONS: Complications are the main driver of readmission after lobectomy for lung cancer. The highest risk was related to postoperative events requiring a procedure or medical therapy necessitating inpatient care.

Survival and Health Care Use After Deep Brain Stimulation for Parkinson's Disease.

OBJECTIVES: To compare long-term survival of Parkinson's disease (PD) patients with deep brain stimulation (DBS) to matched controls, and examine whether DBS was associated with differences in injurious falls, long-term care, and home care. METHODS: Using administrative health data (Ontario, Canada), we examined DBS outcomes within a cohort of individuals diagnosed with PD between 1997 and 2012. Patients receiving DBS were matched with non-DBS controls by age, sex, PD diagnosis date, time with PD, and a propensity score. Survival between groups was compared using the log-rank test and marginal Cox proportional hazards regression. Cumulative incidence function curves and marginal subdistribution hazard models were used to assess effects of DBS on falls, long-term care admission, and home care use, with death as a competing risk. RESULTS: There were 260 DBS recipients matched with 551 controls. Patients undergoing DBS did not experience a significant survival advantage compared to controls (log-rank test p = 0.50; HR: 0.89, 95% CI: 0.65-1.22). Among patients <65 years of age, DBS recipients had a significantly reduced risk of death (HR: 0.49, 95% CI: 0.28-0.84). Patients receiving DBS were more likely than controls to receive care for falls (HR: 1.56, 95% CI: 1.19-2.05) and home care (HR: 1.59, 95% CI: 1.32-1.90), while long-term care admission was similar between groups. CONCLUSIONS: Receiving DBS may increase survival for younger PD patients who undergo DBS. Future studies should examine whether survival benefits may be attributed to effects on PD or the absence of comorbidities that influence mortality.

Factors Associated With Successful Postoperative Day One Discharge After Anatomic Lung Resection.

BACKGROUND: There are no criteria to estimate the risk of early discharge after anatomic lung resection. We hypothesized that demographic, clinical, and surgical variables could be used to predict successful postoperative day 1 (POD1) discharge after anatomic lung resection. METHODS: Patients with POD1 discharge after anatomic lung resection were identified in The Society of Thoracic Surgeons database from 2012 to 2018. Discharges were categorized as successful based on freedom from complications, readmission, or death. A multivariable model identified variables from univariate analysis and was further optimized using stepwise selection. This model was used to create a risk score of success. RESULTS: Among 62,785 patients who underwent anatomic lung resection, 2480 (3.9%) were discharged on POD1. Of the 2480 patients, 2129 (85.8%) had successful discharge and 351 (14.2%) had failed discharge due to postoperative complication (282; 11.3%), readmission (151; 6.1%), or death (9; 0.4%). In univariable analysis, successful POD1 discharge was associated with younger age, female sex, video-assisted thoracic surgery, higher forced expiratory volume in 1 second and diffusion capacity of lung for carbon monoxide, shorter operating room times, and lower rates of comorbidities. A risk model for successful discharge incorporated sex, age, body mass index, operative lobe, Zubrod score, American Society of Anesthesiologists class, coronary artery disease, chronic obstructive pulmonary disease, video-assisted thoracic surgery approach, and operating room time. Using this model, a risk score created, and derived estimated proportion of successful POD1 discharge varied from 75.6% to 92.9%. CONCLUSIONS: Demographic, clinical, and surgical variables are associated with successful POD1 discharge. This analysis suggests that a combination of demographic factors is associated with failed early discharge, and this understanding can be used in conjunction with clinical judgment to facilitate decisions regarding appropriateness of POD1 discharge.

Trends in the Surgical Treatment of Pseudotumor Cerebri Syndrome in the United States.

Importance: Optic nerve sheath fenestration (ONSF) and cerebrospinal fluid shunting are sometimes used to treat pseudotumor cerebri syndrome (PTCS), but their use patterns are unknown. Objectives: To investigate the frequency of surgical PTCS treatment in the United States and to compare patients undergoing ONSF with those treated with shunting. Design, Setting, and Participants: This was a retrospective longitudinal cross-sectional study. Inpatient data were obtained from the National Inpatient Sample (NIS), and outpatient surgical center data were obtained from the National Survey of Ambulatory Surgery (NSAS) and National Hospital Ambulatory Medical Care Survey (NHAMCS). Included in the analysis were 10 720 patients aged 18 to 65 years with a diagnosis code for PTCS, excluding venous thrombosis and other causes of intracranial hypertension. Time trends were explored and logistic regression was used to measure differences according to age, race/ethnicity, sex, Elixhauser comorbidity index, and other patient and hospital characteristics. Data analysis was performed from March 31 to October 7, 2020. Exposure: Treatment for PTCS, excluding venous thrombosis and other causes of intracranial hypertension. Main Outcomes and Measures: Annual number of PTCS-related admissions, ONSFs, and shunt procedures from 2002-2016. Patient and hospital-level characteristics of patients with PTCS undergoing ONSF or shunting were compared. Results: Between 2010 and 2016, 297 ONSFs were performed and 10 423 shunts were placed as treatment for PTCS. The procedures were most commonly performed in individuals aged 26 to 35 years (39.4%), and 9920 (92.4%) of the surgically treated patients were women. ONSF was more common among younger patients (eg, adjusted odds ratio [AOR] for patients ≥46 years vs those 18-25 years, 0.22; 95% CI, 0.08-0.61) and in Black, Hispanic, or other minority populations (AOR, 2.37; 95% CI, 1.31-4.30) and less common in the South (AOR, 0.34; 95% CI, 0.13-0.88) and West (AOR, 0.15; 95% CI, 0.04-0.58) compared with the Northeast. Total PTCS-related hospitalizations increased from 6081 (95% CI, 5137-7025) in 2002 to 18 020 (95% CI, 16 607-19 433) in 2016. Shunting increased from 2002 to 2011 and subsequently plateaued and declined. ONSF was used much less frequently, and use has not increased. No instances of outpatient ONSF or shunting for PTCS were recorded in the NSAS or NHAMCS databases. Conclusions and Relevance: This study's findings suggest that shunting is more common than ONSF and that the use gap has widened as shunting has increased. However, because overall PTCS-related hospitalizations have increased even more rapidly, the percentage of inpatients with PTCS undergoing surgery has decreased. These trends may reflect changes in medical treatment practices and outcomes or growing limitations in access to ophthalmic surgical expertise.

Comorbid disease drives short-term hospitalization outcomes in patients with multiple sclerosis.

OBJECTIVE: Readmission is used as a quality indicator and is the primary target outcome for disease-modifying therapy (DMT) for multiple sclerosis (MS). However, data on readmissions for patients with MS are limited. METHODS: Using the US Nationwide Readmissions Database, we performed a retrospective cohort study of adults hospitalized for MS in 2014. Primary study outcomes were within 30- and 90-day readmissions. Descriptive analyses compared patient, clinical, and hospital variables readmission status. Multivariable logistic regression models estimated the associations between these variables and readmission. RESULTS: Of 16,629 individuals meeting the study criteria, most were women (73.7%), aged 35-54 years (48.0%), and Medicare program participants (36.8%). In total, 49.7% of inpatients with MS had 1-2 comorbid medical conditions and 23.7% had 3 or more. Having 3 or more comorbidity conditions associated with increased adjusted odds of the 30-day readmission (adjusted odds ratio [AOR] 1.92, 1.34-2.74). Anemia (AOR 1.62, 1.22-2.14), rheumatoid arthritis/collagen vascular diseases (AOR 2.20, 1.45-3.33), congestive heart failure (AOR 2.43, 1.39-4.24), chronic pulmonary disease (AOR 1.35, 1.02-1.78), diabetes with complications (AOR 2.27, 1.45-3.56), hypertension (AOR 1.25, 1.03-1.53), obesity (AOR 1.35, 1.05-1.73), and renal failure (AOR 1.68, 1.06-2.67) were associated with the 30-day readmission. Medicare insurance and nonroutine discharge were also associated with readmission, whereas patient characteristics (sex, age, and socioeconomic status) were not. The most frequent (26.7%) reason for readmission was multiple sclerosis. Ninety-day analyses produced similar findings. CONCLUSIONS: Comorbid diseases were associated with the readmission for persons with multiple sclerosis. Evaluations of the real-world effectiveness for DMTs in reducing hospitalizations in patients with MS may need to consider comorbid disease burden and management.

Self-reported vision and hallucinations in older adults: results from two longitudinal US health surveys.

BACKGROUND: Vision loss may be a risk factor for hallucinations, but this has not been studied at the population level. METHODS: To determine the association between self-reported vision loss and hallucinations in a large community-based sample of older adults, we performed a cross-sectional and longitudinal analysis of two large, nationally representative US health surveys: the National Health and Aging Trends Study (NHATS) and the Health and Retirement Study (HRS). Visual impairment and hallucinations were self- or proxy-reported. Multivariate single and mixed effects logistic regression models were built to examine whether visual impairment and history of cataract surgery were associated with hallucinations. RESULTS: In NHATS (n = 1520), hallucinations were more prevalent in those who reported difficulty reading newspaper print (OR 1.77, 95% confidence interval (CI): 1.32-2.39) or recognising someone across the street (OR 2.48, 95% CI: 1.86-3.31) after adjusting for confounders. In HRS (n = 3682), a similar association was observed for overall (OR 1.32, 95% CI: 1.08-1.60), distance (OR 1.61, 95% CI: 1.32-1.96) and near eyesight difficulties (OR 1.52, 95% CI: 1.25-1.85). In neither sample was there a significant association between cataract surgery and hallucinations after adjusting for covariates. CONCLUSIONS: Visual dysfunction is associated with increased odds of hallucinations in the older US adult population. This suggests that the prevention and treatment of vision loss may potentially reduce the prevalence of hallucinations in older adults.

Association of postoperative complications and outcomes following coronary artery bypass grafting.

BACKGROUND: The long-term effects of postoperative complications following coronary artery bypass grafting (CABG) are unknown. METHODS: Medicare-linked records from the Society of Thoracic Surgeons Adult Cardiac Surgery Database were queried for isolated CABG records from 2007 through 2012. Unadjusted and adjusted associations between individual postoperative complications and both mortality and all-cause rehospitalization were evaluated to 7 years using Cox proportional-hazards models and cumulative incidence functions. Because of nonproportional hazards, associations are presented as early (0 to 90 days) and late (90 days to 7 years). RESULTS: Of the 294,533 isolated CABG patients who had records linked to Medicare for long-term follow-up (median age, 73 years; 30% female), 120,721 (41%) experienced at least 1 of the complications of interest, including new-onset atrial fibrillation (30.0%), prolonged ventilation (12.3%), renal failure (4.5%), reoperation (3.5%), stroke (1.9%), and sternal wound infection (0.4%). Each of the 6 postoperative complications was associated with a significantly increased risk of mortality and rehospitalization to 7 years despite adjustment for baseline characteristics and the presence of multiple complications. Although the predominant effect of postoperative complications was observed in the first 90 days, the increased risk-adjusted hazard for death and rehospitalization continued through 7 years. CONCLUSIONS: Postoperative complications are associated with an increased risk of both early and late mortality and all-cause rehospitalization, particularly during the "value" window within 90 days of CABG. These findings underscore the need to develop avoidance strategies as well as cost-adjustment methods for each of these complications.

A contemporary analysis of goiters undergoing surgery in the United States.

INTRODUCTION: We identified disparities and at-risk populations among patients with goiters undergoing thyroidectomy. MATERIALS AND METHODS: The National Inpatient Sample (NIS) database was queried for patients with goiter who underwent thyroidectomy between 2009 and 2013. Multivariable logistic regression was used to determine factors associated with goiters undergoing thyroidectomy. RESULTS: The study consisted of 103,678 patients with thyroidectomy and a goiter diagnosis, which included: simple goiter (n = 7,692, 7.42%), nodular goiter (n = 73,524, 70.92%), thyrotoxicosis (n = 14,043, 13.54%), thyroiditis (n = 1,248, 1.20%), and thyroid cancer (n = 7,169, 6.92%). Factors associated with operation for simple goiter included age >65 years (AOR 1.43 [1.15-1.79]), black race (AOR 1.35 [1.14-1.58]), and being uninsured (AOR 2.13 [1.52-2.98]). Patients with cancerous goiters undergoing thyroidectomy were less likely to be Black (AOR 0.38 [0.31-0.48]) or uninsured (AOR 0.25 [0.07-0.89]). DISCUSSION: Understanding disparities within populations undergoing thyroidectomy for goiter may allow for targeted efforts to more effectively treat goiters nationwide.

Inpatient gastrostomy in Huntington's disease: Nationwide analysis of utilization and outcomes compared to amyotrophic lateral sclerosis.

BACKGROUND: Huntington's disease (HD) causes dysphagia and dementia, both of which are risk factors for malnutrition. Gastrostomy is used to sustain enteral intake in neurodegenerative diseases and specifically improves outcomes in ALS, but its indications and outcomes in HD are understudied. OBJECTIVE: To explore the indications and outcomes for gastrostomy for HD. METHODS: We performed a retrospective cross-sectional analysis of all HD admissions in the National Inpatient Sample. Logistic regression models compared the patient- and hospital-level characteristics associated with gastrostomy placement in HD and the prevalence of associated diagnoses in HD vs. ALS gastrostomy patients. We also examined in-hospital mortality, length of stay (LOS), and discharge status. RESULTS: Between 2000 and 2010, 5.12% (n = 1614) of HD admissions included gastrostomy tube placement. Gastrostomy patients were more likely to be Black (adjusted odds ratio [AOR] 1.55, 95% CI: 1.09-2.21) and have Medicare coverage (AOR 1.43, 95% CI: 1.0-2.05). The most common comorbidities were aspiration pneumonia (34.1%), dementia (31.3%), malnutrition (30.3%), and dysphagia (29.5%). Dementia and delirium were associated with discharge type but not LOS. Aspiration pneumonia, sepsis, and Elixhauser comorbidity index were associated with LOS but not discharge type. Compared to 7908 ALS gastrostomy patients, those with HD more frequently had aspiration pneumonia (34.1% vs. 20.5%, p < 0.0001), sepsis (28.1% vs. 13.7%, p < 0.0001), prolonged LOS (OR 1.14, 95% CI: 1.02-1.28), and skilled nursing facility discharge (p < 0.0001, Wald chi square test). CONCLUSIONS: Gastrostomy is frequently performed in HD patients with dementia and aspiration pneumonia who are at increased risk for negative hospitalization outcomes.

Readmissions after hospital care for meningitis in the United States.

BACKGROUND: Our objectives were to (1) characterize patient and clinical characteristics of adults hospitalized with meningitis; (2) describe meningitis hospitalization outcomes, including 30- and 90-day readmissions; and (3) determine whether clinical, patient, or index hospitalization characteristics are associated with readmission and readmission outcomes. METHODS: This retrospective study of the 2014 National Readmissions Database extracted data on hospitalized adults with a principal diagnosis of meningitis and examined hospitalization outcomes using descriptive statistics. Logistic regression models were built to determine whether characteristics were associated with 30- or 90-day readmissions. RESULTS: For the 30-day readmission analyses, 18,883 adults qualified. Meningitis hospitalizations commonly involved adults 25 to 54 years of age who were insured by private carriers. The readmission rates were 7.0% at 30 days and 11.4% at 90 days. Readmission was associated with greater comorbidity burden (2 conditions: adjusted odds ratio [AOR] = 1.60, range 1.24-2.08; 3 conditions: AOR = 1.92, range 1.43-2.58; 4+ conditions: AOR = 2.68, range 2.04-3.51 vs 0 or 1 condition), public insurance (Medicare: AOR = 1.85, range 1.30-2.62; Medicaid: AOR = 1.48, range 1.16-1.90 vs private insurance), and medical error (AOR = 1.43, range 1.07-1.91). Readmissions were most often for meningitis, septicemia, or medical complications. CONCLUSIONS: Readmission after hospitalization for meningitis is associated with both fixed and modifiable factors. More research is needed to determine which post-meningitis readmissions are preventable.

Acute readmission following deep brain stimulation surgery for Parkinson's disease: A nationwide analysis.

INTRODUCTION: Deep brain stimulation (DBS) surgery is an efficacious, underutilized treatment for Parkinson's disease (PD). Studies of DBS post-operative outcomes are often restricted to data from a single center and consider DBS in isolation. National estimates of DBS readmission and post-operative outcomes are needed, as are comparisons to commonly performed surgeries. METHODS: This study used datasets from the 2013 and 2014 Nationwide Readmissions Database (NRD). Our sample was restricted to PD patients discharged alive after hospitalization for DBS surgery. Descriptive analyses examined patient, clinical, hospital and index hospitalization characteristics. The all-cause, non-elective 30-day readmission rate after DBS was calculated, and logistic regression models were built to examine factors associated with readmission. Readmission rates for the most common surgical procedures were calculated and compared to DBS. RESULTS: There were 6058 DBS surgeries for PD in our sample, most often involving a male aged 65 and older, who lived in a high socioeconomic status zip code. DBS patients had an average of four comorbidities. With respect to outcomes, the majority of patients were discharged home (95.3%). Non-elective readmission was rare (4.9%), and was associated with socioeconomic status, comorbidity burden, and teaching hospital status. Much higher acute, non-elective readmission rates were observed for common procedures such as upper gastrointestinal endoscopy (16.2%), colonoscopy (14.0%), and cardiac defibrillator and pacemaker procedures (11.1%). CONCLUSION: Short-term hospitalization outcomes after DBS are generally favorable. Socioeconomic disparities in DBS use persist. Additional efforts may be needed to improve provider referrals for and patient access to DBS.

A Study of Practice Behavior for Endotracheal Intubation Site for Children With Congenital Heart Disease Undergoing Surgery: Impact of Endotracheal Intubation Site on Perioperative Outcomes-An Analysis of the Society of Thoracic Surgeons Congenital Cardiac Anesthesia Society Database.

BACKGROUND: In adults undergoing cardiopulmonary bypass surgery, oral intubation is typically preferred over nasal intubation due to reduced risk of sinusitis and infection. In children, nasal intubation is more common and sometimes preferred due to perceived benefits of less postoperative sedation and a lower risk for accidental extubation. This study sought to describe the practice of nasal intubation in the pediatric population undergoing cardiopulmonary bypass surgery and assess the risks/benefits of a nasal route against an oral one. METHODS: Patients <18 years of age in the Society of Thoracic Surgeons Congenital Heart Surgery Database between January 2010 and December 2015 were included. Patients with a preoperative endotracheal tube, tracheostomy, or known airway anomalies were excluded. Multivariable modeling was used to assess the association between route of tracheal intubation and a composite measure of infection risk (wound infection, mediastinitis, septicemia, pneumonia, and endocarditis). Covariates were included to adjust for important patient characteristics (eg, weight, age, comorbidities), case complexity, and center effects. Secondary outcomes included length of intubation, hospital length of stay, and airway complications including accidental extubations. We also performed a subanalysis in children <12 months of age in high-volume centers (>100 cases/y) examining how infection risk may change with age at the time of surgery. RESULTS: Nasal intubation was used in 41% of operations in neonates, 38% in infants, 15% in school-aged children, and 2% in adolescents. Nasal intubation appeared protective for accidental extubation only in neonates (P = .02). Multivariable analysis in infants and neonates showed that the nasal route of intubation was not associated with the infection composite (relative risk [RR], 0.84; 95% CI, 0.59-1.18) or a shorter length of stay (RR, 0.992; 95% CI, 0.947-1.039), but was associated with a shorter intubation length (RR, 0.929; 95% CI, 0.869-0.992). Restricting to high-volume centers showed a significant interaction between age and intubation route with a risk change for infection occurring between approximately 6-12 months of age (P = .003). CONCLUSIONS: While older children undergoing nasal intubation trend similar to the adult population with an increased risk of infection, nasal intubation in neonates and infants does not appear to carry a similar risk. Nasal intubation in neonates and infants may also be associated with a shorter intubation length but not a shorter length of stay. Prospective studies are required to better understand these complex associations.

Understanding nationwide readmissions after thyroid surgery.

BACKGROUND: The 30-day readmission rate is increasingly utilized as a metric of quality that impacts reimbursement. To date, there are no nationally representative data on readmission rates after thyroid surgery. We aimed to determine national readmission rates after inpatient thyroidectomy operations and whether select clinical factors were associated with increased odds of postthyroidectomy readmission. METHODS: Using the 2014 Nationwide Readmissions Database, we identified patients undergoing inpatient thyroid surgery as defined by the International Classification of Diseases, Ninth Revision, procedure codes for thyroid lobectomy, partial thyroidectomy, complete thyroidectomy, and substernal thyroidectomy. Descriptive statistics were used to report readmission rates, most common diagnosis and causes of readmission, and timing of presentation after discharge. Multivariable logistic regression models controlling for potential confounders were used to determine whether select factors were associated with 30-day readmission. RESULTS: A total of 22,654 patients underwent inpatient thyroid surgery during the study period, 990 of whom (4.4%) were readmitted within 30 days. Among these, the most common diagnoses during readmission were disorders of mineral metabolism and hypocalcemia, accounting for 36.0% and 26.6% of readmissions, respectively. This held true regardless of the apparent indication for thyroid surgery (goiter, cancer, or thyroid function disorder) or timing of readmission after discharge. Calcium-related abnormalities were the top diagnoses at readmissions (22.1%). Most readmissions (54.6%) occurred within 7 days of discharge, with 24.6% within the first 2 days Factors associated with an increased odds of readmission included having Medicare (adjusted odds ratio [AOR] 1.47 and 95% confidence interval [CI] 1.03-2.11) or Medicaid insurance (AOR 1.44 [CI 1.04-1.99]), being discharged to inpatient post acute care (AOR 2.31 [CI 1.48-3.62]) or to home health care (AOR 1.78 [CI 1.21-2.63]), having an Elixhauser comorbidity score ≥ 4 (AOR 2.04 [CI 1.27-3.26]), and a duration of stay ≥2 days after the thyroid surgery (AOR 2.7 [CI 1.9-3.82]). The only complication during index admission associated with increased odds of readmission was hypocalcemia (AOR 1.5 [CI 1.1-2.06]. Indications for thyroid surgery were not associated with increased odds of readmission. CONCLUSION: Readmissions after thyroid surgery are relatively low and occur early after surgery. The most common diagnoses identified on readmission were calcium and mineral metabolism disorders, which also were the most common cause of readmission. Socioeconomic factors, comorbidities, and complications during the index admissions were found to be associated with nonelective, postthyroidectomy readmissions. Recognition of these risk factors may guide the development of interventions and protocols to decrease readmissions.

Adverse Drug Events as a Reason for Adult Hospitalization: A Nationwide Readmission Study.

BACKGROUND: Adverse drug events (ADEs) are common; however, there are limited data on the impact of ADEs on post-discharge outcomes. OBJECTIVES: To identify ADEs responsible for readmission within 6 months of hospital discharge in the United States. Secondary objectives were to examine whether demographic, clinical, and hospital characteristics were associated with ADE readmission. METHODS: We identified all adults hospitalized between January and June using the 2014 Nationwide Readmission Database. Nationally representative estimates of hospitalization outcomes and ADE-related readmissions, excluding ADEs from illicit drug use and intentional overdose, were computed using survey weighting methods. Associations between patient, clinical, and hospital characteristics, and ADE readmission were assessed using unconditional logistic regression. RESULTS: We identified 10 889 282 hospitalizations meeting inclusion criteria. The 6-month readmission rate was 17.8% (n = 1 943 111). A total of 6964 readmissions were attributed to an ADE, most frequently "poisoning by opiates and related narcotics" (18.3%), "poisoning by benzodiazepines" (11.9%), and "dermatitis due to drugs and medicines taken internally" (9.4%). Factors identified as being positively associated with ADE readmission included age <60 years (adjusted odds ratio [AOR] = 1.69; 95% CI = 1.45-1.97), Medicare insurance (AOR = 2.93; 95% CI = 2.55-3.38), and discharge to home health care (AOR = 1.42; 95% CI = 1.28-1.59). Conclusion and Relevance: Readmissions caused by ADEs are frequently attributed to opiate and benzodiazepine poisonings, and factors such as age, insurance status, and discharge disposition were found to be associated with ADE readmission. Future studies are needed to examine whether ADE readmissions are preventable.

Contemporary Surgical Management of Hypertrophic Cardiomyopathy in the United States.

BACKGROUND: The primary surgical therapy for hypertrophic cardiomyopathy with obstruction is septal myectomy (SM). The current outcomes of SM with and without concomitant mitral operations in the United States was examined using The Society of Thoracic Surgeons database. METHODS: From July 2014 through June 2017, 4,274 SM operations were performed. Emergent status, endocarditis, aortic stenosis, and planned aortic valve operations were excluded. In the final cohort of 2,382 patients, 1,581 (66.4%) received SM alone (group 1), and 801 (33.6%) had SM with mitral valve repair or replacement (group 2). Group 2 was subdivided into mitral valve repair (MVr [n = 500]) and mitral valve replacement (MVR [n = 301]). Baseline characteristics were compared and risk-adjusted operative mortality and major morbidity were evaluated between treatment groups. RESULTS: Baseline comorbidity was lower in group 1 versus group 2 and for MVr versus MVR. Operative mortality and major morbidity was lower for group 1 versus 2 (1.6% versus 2.8%, p = 0.046, and 10.9% versus 20.0%, p < 0.001, respectively). For patients with severe 3-4+ mitral regurgitation, SM alone was effective in reducing mitral regurgitation in 85.5% (355 of 415), and SM with MVr was effective in 88.0% (176 of 200; p = 0.4061). After risk adjustment, odds ratio for composite of mortality and major morbidity for group 2 versus group 1 was 1.8 (95% confidence interval: 1.4 to 2.4, p < 0.0001). CONCLUSIONS: Septal myectomy for hypertrophic cardiomyopathy is safe. Septal myectomy alone may have risk-adjusted outcome advantages over SM with mitral valve repair or replacement. Septal myectomy and SM with MVr provide similar reduction in mitral regurgitation. Further longitudinal analyses are required to define technical efficacy and outcomes in selected pathoanatomic groups.

Sociodemographic Factors Associated With Hospital Care for Pediatric Migraine: A National Study Using the Kids' Inpatient Dataset.

BACKGROUND: Although migraine often starts in childhood or adolescence, hospital care for migraine in children is not well described. We examined patient and hospital characteristics associated with hospital care for migraine among children in the United States. METHODS: We queried the Kids' Inpatient Database (2003 to 2009) for hospitalizations of children aged 3-20. Sociodemographic and hospital characteristics were compared between hospitalizations for migraine and for other common medical conditions. Multivariate logistic regression models estimated the associations between patient, hospital, and socioeconomic characteristics and inpatient migraine care. RESULTS: We identified 11,696 pediatric migraine hospitalizations, the majority (68.7%) occurring at teaching hospitals, involving a female (68.8%) child, ages 13-20 (71%, mean age: 14.6 years). As compared to the overall inpatient sample, migraine hospitalizations were less likely to involve children who were Black (adjusted odds ratio [AOR] 0.54, 95% confidence interval [CI] 0.49 to 0.60), Hispanic (AOR = 0.58, 95% CI 0.50 to 0.68), or Asian (AOR = 0.42, 95% CI 0.32 to 0.55), and more likely to involve females (AOR = 1.49, 95% CI 1.40 to 1.59). Migraine inpatients were more likely to live in higher income postal ZIP code areas (versus lowest ZIP code income quartile: AOR = 1.32, 95% CI 1.18 to 1.48). The average length of stay for migraine was 2.54 (SEM 0.6) days. CONCLUSIONS: Children who are hospitalized for migraines have distinct sociodemographic characteristics and a short length of stay. Understanding the reasons for these variations will inform the design of interventions aimed at reducing the need for pediatric migraine hospitalization.
