Primary payer status is significantly associated with postoperative mortality, morbidity, and hospital resource utilization in pediatric surgical patients within the United States

Sociodemographic differences in opioid use and recovery following ambulatory pediatric urologic procedures

Our aim was to examine associations between sociodemographic factors and postoperative opioid use and recovery among pediatric patients undergoing outpatient urologic procedures. We retrospectively evaluated 831 patients undergoing ambulatory urologic procedures from 2013 to 2017 at an urban pediatric hospital. Patients were evaluated for days of opioid use and days until return to baseline behavior. Differences in outcomes by race/ethnicity, primary language, median neighborhood household income, and health insurance type were analyzed using negative binomial regression models. Overall, patients reported a median of 1.0 day (IQR: 2.0) of postoperative opioid use and 3.0 days (IQR: 6.0) of recovery time. After controlling for covariates, patients with non-English speaking parents took opioids for 26.5% (95% CI: 11.4-41.7%) longer and had 27.8% (95% CI: 8.1-51.0%) longer recovery time than patients with English-speaking parents. Hispanic patients took opioids for 27.5% (95% CI: 0.1-54.9%) longer than White patients. Patients with public insurance used opioids for 47.6% (95% CI: 5.0-107.4%) longer than privately insured patients. Non-English speaking, Hispanic, and publicly insured patients had a longer duration of postoperative opioid use than primarily English-speaking, White, and privately insured patients, respectively. Identifying these disparities is important for designing equitable postoperative care pathways.

Effect of insurance status on perioperative outcomes after robotic pancreaticoduodenectomy: a propensity-score matched analysis

The influence of Medicaid or being uninsured is prevailingly thought to negatively impact a patient's socioeconomic and postoperative course, yet little has been published to support this claim specifically in reference to robotic pancreaticoduodenectomy. This study was undertaken to determine impact of health insurance type on perioperative outcomes in patients undergoing robotic pancreaticoduodenectomy. Following IRB approval, we prospectively followed 364 patients who underwent robotic pancreaticoduodenectomy. Patients were stratified by insurance status (i.e., Private, Medicare, and Medicaid/Uninsured); 100 patients were 2:2:1 propensity-score matched by age, BMI, ASA class, pathology, 8th edition AJCC staging, and tumor size. Perioperative variables were compared utilizing contingency testing and ANOVA. Statistical significance was accepted at a p-value ≤ 0.05 and data are presented as median (mean ± SD). The 100 patients undergoing propensity-score matching were 64 (65 ± 9.1) years old with a BMI of 27 (27 ± 4.9) kg/m2 and ASA class of 3 (3 ± 0.5). Operative duration was 421 (428 ± 105.9) minutes and estimated blood loss was 200 (385 ± 795.0) mL. There were 4 in-hospital deaths and 8 readmissions within 30 days of discharge. Total hospital cost was $32,064 (38,014 ± 22,205.94). After matching, no differences were found in pre-, intra-, and short-term postoperative variables among patients with different insurances, including hospital cost and time to initiate adjuvant treatment, which was 8 (9 ± 7.9) weeks for patients with malignant disease. In our hepatopancreaticobiliary program, health insurance status did not impact perioperative outcomes or hospital costs. These findings highlight that financial coverage does not influence quality of perioperative care, reinforcing the equity of robotic surgery.

Postprocedural Complications Hospitalization Pattern Among Paediatric Patients at National Health Service Trusts: An Ecological Study in England and Wales

Purpose

To analyze the hospitalization patterns associated with postprocedural complications among the pediatric population in England and Wales over the past two decades.

Patients and Methods

This was an ecological study using hospital admission data extracted from the Hospital Episode Statistics database in England and the Patient Episode Database for Wales for the period between April 1999 and April 2020. Postprocedural complications related hospital admissions were identified using the 10th version of the International Statistical Classification of Diseases (ICD) system (D78, E89, H59, H95, J95, L76, M96, and N99).

Results

The rate of hospital admissions declined by 2.1% [from 8.32 (95% CI 7.75-8.88) per 100,000 persons in 1999 to 8.15 (95% CI 7.61-8.68) per 100,000 persons in 2020, p>0.05]. The primary reasons for hospital admissions associated with postprocedural complications were related to the respiratory system, genitourinary system, and ear and mastoid process, constituting 43.0%, 23.8%, and 23.0% of cases, respectively.

Conclusion

The trend of postprocedural complications among the pediatric population has been stable in the past two decades. Continuous monitoring of the hospitalization pattern for this type of complication is important due to advancements in healthcare provision and to improve patient care and safety. Future studies are needed to examine gender-based differences related to postprocedural complications and identify important preventable risk factors.

Surgical prescription opioid trajectories among state Medicaid enrollees

OBJECTIVE

The objective of this study was to evaluate opioid use trajectories among a sample of 10,138 Medicaid patients receiving one of six index surgeries: lumbar spine, total knee arthroplasty, cholecystectomy, appendectomy, colon resection, and tonsillectomy.

DESIGN

Retrospective cohort.

SETTING

Administrative claims data.

PATIENTS AND PARTICIPANTS

Patients, aged 13 years and older, with 15-month continuous Medicaid eligibility surrounding index surgery, were selected from single-state Medicaid medical and pharmacy claims data for surgeries performed between 2014 and 2017.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

Baseline comorbidities and presurgery opioid use were assessed in the 6 months prior to admission, and patients' opioid use was followed for 9 months post-discharge. Generalized linear model with log link and Poisson distribution was used to determine risk of chronic opioid use for all risk factors. Group-based trajectory models identified groups of patients with similar opioid use trajectories over the 15-month study period.

RESULTS

More than one in three (37.7 percent) patients were post-surgery chronic opioid users, defined as the dichotomous outcome of filling an opioid prescription 90 or more days after surgery. Key variables associated with chronic post-surgery opioid use include presurgery opioid use, 30-day post-surgery opioid use, and comorbidities. Latent trajectory modeling grouped patients into six distinct opioid use trajectories. Associates of trajectory group membership are reported.

CONCLUSIONS

Findings support the importance of surgeons setting realistic patient expectations for post-surgical opioid use, as well as the importance of coordination of post-surgical care among patients failing to fully taper off opioids within 1-3 months of surgery.

Causal analysis of socioeconomic influence on cost of care: The emergency general surgery model

BACKGROUND

This study characterizes the relationship between SES and cost of emergency general surgery (EGS).

METHODS

Utilizing Florida AHCA (2016-2020), patients undergoing the 7 most common EGS were identified. Distressed Community Index (DCI) was linked, which quantifies SES through unemployment, poverty, and other factors. Zipcodes are assigned DCI 0 (no distress) to 100 (severe distress). Linear regression with stepwise elimination was conducted. Top and bottom DCI quintiles were propensity matched for demographics, comorbidities, and procedure.

RESULTS

144,924 admissions were included. Linear regression eliminated 5 of 28 variables, including DCI. Top cost contributors were discharge-43%; comorbidities-14%; age-9%. Distressed patients received less home health and inpatient rehab. Distressed patients utilized 4-/5-star hospitals less and had higher odds of mortality.

CONCLUSION

Discharge, mortality, and hospital characteristics differ significantly between DCI communities. Total cost was similar, and is strongly influenced by discharge status, while DCI had no effect.

How can pediatric surgeons address racism and become actively anti-racist?

BACKGROUND/PURPOSE

This is an article submitted on behalf of the Canadian Association of Pediatric Surgeons. We assert that Pediatric Surgeons must work to dismantle systemic racism. Pediatric Surgeons have expertise in both common and rare surgical diseases affecting patients ranging from premature neonates to adolescents. Thus, our professional obligation is to transform our health and social systems to prevent the harms of racism to our patients.

METHODS

Specific to the Canadian context, we describe a brief history, the ongoing impact on individuals and communities, and the harmful effect on the surgical community and trainees. Finally, we developed a series of practical recommendations to help surgeons become actively anti-racist.

RESULTS

Four primary recommendations are made: (1) Increasing and supporting anti-racism education; (2) Changing individual behaviours to combat racism; (3) Developing strategies for organizational change; and (4) Committing to diversity in leadership.

CONCLUSION

As surgeons, we are actors of change, and we can take meaningful steps to combat racism in our health systems.

Fecal continence disparities in patients with idiopathic constipation treated at referral institutions for pediatric colorectal surgery

PURPOSE

Fecal continence is a concern for many patients with idiopathic constipation and can significantly impact quality of life. It is unknown whether racial, ethnic, and socioeconomic disparities are seen in fecal continence within the idiopathic constipation population. We aimed to evaluate fecal continence and associated demographic characteristics in children with idiopathic constipation referred for surgical evaluation.

METHODS

A multicenter retrospective study of children with idiopathic constipation was performed at sites participating in the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC). All patients >3y of age with idiopathic constipation diagnosis were included. The primary outcome was fecal continence, categorized as complete (no accidents ever), daytime (no accidents during the day), partial (occasional incontinence day/night), and none (incontinent). We evaluated for associations between fecal continence and race, sex, age, insurance status, and other patient-level factors, employing Kruskal-Wallis and trend tests.

RESULTS

458 patients with idiopathic constipation from 12 sites were included. The median age of diagnosis was 4.1 years. Only 25% of patients referred for surgical evaluation were completely continent. Age at the visit was significantly associated with fecal continence level (p = 0.002). In addition, patients with public and mixed public and private insurance had lower levels of continence (p<0.001). Patients with developmental delay were also more likely to have lower continence levels (p = 0.009) while diagnoses such as anxiety, ADD/ADHD, autism, depression, obsessive-compulsive disorder were not associated. Approximately 30% of patients had an ACE operation (antegrade continence enema) at a median age of 9.2 years at operation. Black patients were significantly less likely to undergo ACE operation (p = 0.016) when compared to white patients.

CONCLUSION

We observed data that suggest differences in fecal incontinence rates based on payor status. Further investigation is needed to characterize these potential areas of disparate care.

The effect of socioeconomic factors on patient outcomes in cardiac surgery

OBJECTIVES

Healthcare delivery is heterogenous; the reasons for this are numerous and complex. Patient-specific factors including geography, income, insurance status, age, and gender have been shown to bias surgical outcomes. Utilizing a prospectively collected all-payer database, we aim to evaluate the influence of socioeconomic factors on mortality and length of stay (LOS) after common cardiac surgical procedures.

METHODS

We utilized the National Inpatient Sample, Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality for the year 2019. We included patients undergoing coronary artery bypass grafting (CABG), aortic valve replacement (AVR), transcatheter aortic valve replacement (TAVR), and combined AVR/CABG using the 10th revision of the International Classification of Diseases procedure codes. AVR and CABG were combined into a separate cohort as this was felt to represent a different pathology than isolated valvular or coronary arterial disease. Baseline demographics were summarized. Multivariable regression was performed within each procedure group to model the odds of in-hospital mortality and hospital LOS with age, sex, insurance, zip-code median household income, and location as predictors.

RESULTS

Baseline patient characteristics including gender, income, geography, and payer status were similar between CABG, AVR, and AVR/CABG. TAVR patients had a higher proportion of female sex and Medicare as the primary payer, with an overall greater age. Multivariable Cox proportional hazards regression found that higher income was strongly associated with decreased LOS following AVR and CABG, and moderately associated in TAVR and AVR/CABG. Private insurance was associated with a decreased LOS in patients undergoing CABG, AVR, TAVR, and AVR/CABG. Female sex and increased age were associated with increased odds of mortality in TAVR, CABG, and AVR/CABG. Private insurance was associated with a decreased odds of mortality in patients undergoing AVR.

CONCLUSIONS

These findings reveal significant disparities in patient outcomes after routine cardiac operations that are associated with socioeconomic status. Patients who did not have private insurance or had lower incomes were found to be at risk for increased LOS. Women were at a higher risk of mortality for several operations, a finding which has been previously described elsewhere. Private insurance conveyed a decreased odds of mortality in patients undergoing AVR. This data set serves to highlight differences in healthcare outcomes based on a variety of socioeconomic, geographic, and other inherent factors. Additional research is needed to identify the mechanisms behind these disparities with the goal of providing equitable care to all patients.

Factors Associated with Length of Stay and Cost among Pediatric Hospitalizations with a Primary Ophthalmic Diagnosis

PURPOSE

To investigate factors associated with prolonged length of stay and high cost among pediatric hospitalizations with a primary ophthalmic diagnosis.

METHODS

This retrospective, cross-sectional study utilized data on pediatric admissions with a primary ophthalmic diagnosis from the multicenter 2016 Kids' Inpatient Database. Multivariable logistic regression models adjusted for demographic, hospital, and admission characteristics were used to evaluate factors associated with prolonged stay and high cost, defined as exceeding the 75th percentile (>4 days and $12,642, respectively).

RESULTS

An estimated 6,811 pediatric hospitalizations with a primary ophthalmic diagnosis in the United States in 2016 were included. On adjusted analysis, a prolonged length of stay was more likely with Medicaid (vs. private insurance, OR = 1.19, 95% CI: [1.02, 1.40], p = .03), non-trauma (vs. trauma, OR = 2.77, 95% CI: [2.12, 3.63], p < .001) and urban teaching hospitals (vs. rural, OR = 3.48, 95% CI: [1.04, 11.69], p = .04). A high cost of stay was more likely with higher income levels (Quartile 3 vs. 1, OR = 1.30, 95% CI: [1.02, 1.67], p = .04; Quartile 4 vs. 1, OR = 1.49, 95% CI: [1.08, 2.05], p = .02), private insurance (vs. Medicaid, OR = 1.26, 95% CI: [1.04, 1.53], p = .02), Western hospitals (vs. South, OR = 2.74, 95% CI: [1.83, 4.12], p < .001), and trauma (vs. non-trauma, OR = 3.29, 95% CI: [2.57, 4.21], p < .001). Children and young adults had higher odds of prolonged stay, while adolescents and young adults had higher odds of high cost compared to toddlers (p < .05 for all).

CONCLUSIONS

Additional work addressing the factors associated with higher resource utilization may help promote the delivery of quality inpatient pediatric eye care.

Insurance types are correlated with baseline patient-reported outcome measures in patients with adult spinal deformity

BACKGROUND

Patient-reported outcome measures (PROMs) are increasingly recognized as a key component of healthcare value, allowing comparison of therapeutic impact across different specialties. Prior literature suggests that insurance type may be associated with differing baseline PROMs among patients with degenerative conditions, including lumbar stenosis and hip arthritis. This association, however, has not been investigated for adult spinal deformity (ASD).

METHODS

Baseline PROMs were reviewed from 207 patients with ASD presenting for treatment between 2015 and 2019. The Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function Short Form 10a (PF10a), PROMIS Global-Mental, PROMIS Global-Physical, and visual analogue scale (VAS) for back and leg pain were assessed. Negative binomial regression was used to determine the impact of sociodemographic factors, including insurance type, on severity of symptoms and degree of disability at baseline.

RESULTS

Mean age of the study population was 62.2 +/- 15 years, with 61.8 % male prevalence. The Medicaid population had a greater proportion of Hispanic and non-English speaking patients, compared to commercially insured patients. Medicaid insured patients had significantly greater VAS low back pain scores compared with commercially insured individuals (IRR 1.535, 95 % CI 1.122-2.101, p = 0.007).

CONCLUSIONS

Medicaid insured patients demonstrated worse baseline PROMs at presentation with ASD, as compared to commercially insured or Medicare patients. Stakeholders across spine care delivery should elucidate the etiology of baseline disparities in ASD patients, as they may result from health system asymmetries. In an ecosystem moving toward value-driven treatment algorithms, accounting for and addressing these differences will be necessary to provide equitable care for ASD populations.

Postoperative complications after gastrointestinal pediatric surgical procedures: outcomes and socio-demographic risk factors

BACKGROUND

Several socio-demographic characteristics are associated with complications following certain pediatric surgical procedures. In this comprehensive study, we sought to determine socio-demographic risk factors and resource utilization of children with complications after common pediatric surgical procedures.

METHODS

We performed a population-based cohort study utilizing the 2016 Healthcare Cost and Use Project Kids' Inpatient Database (KID) to identify and characterize pediatric patients (age 0-21 years) in the United States with common inpatient pediatric gastrointestinal surgical procedures: appendectomy, cholecystectomy, colonic resection, pyloromyotomy and small bowel resection. Multivariable logistic regression modeling was used to identify socio-demographic predictors of postoperative complications. Length of stay and hospitalization costs for patients with and without postoperative complications were compared.

RESULTS

A total of 66,157 pediatric surgical hospitalizations were identified. Of these patients, 2,009 had postoperative complications. Male sex, young age, African American and Native American race and treatment in a rural hospital were associated with significantly greater odds of postoperative complications. Mean length of stay was 4.58 days greater and mean total costs were $11,151 (US dollars) higher in the complication cohort compared with patients without complications.

CONCLUSIONS

Postoperative complications following inpatient pediatric gastrointestinal surgery were linked to elevated healthcare-related expenditure. The identified socio-demographic risk factors should be considered in the risk stratification before pediatric surgical procedures. Targeted interventions are required to reduce preventable complications and surgical disparities.

US Nationwide Insight Into All-cause 30-day Readmissions following Inpatient Endoscopic Retrograde Cholangiopancreatography

BACKGROUND AND AIMS

Endoscopic retrograde cholangiopancreatography (ERCP) is associated with a high risk for morbidity, mortality, and hospital readmission. Data regarding those risks in the United States is scarce. We assessed post-ERCP 30-day readmission rates, their etiologies, and impact on the health care system using national data.

METHODS

Using the National Readmission Database 2016, we identified patients who underwent inpatient ERCP from January 2016 to December 2016 using ICD-10-CM procedure codes. The primary endpoint was all-cause 30-day readmission rate. Etiologies of readmission were identified by tallying primary diagnosis. Multivariable logistic regression with complex survey design was used to identify independent risk factors associated with readmission.

RESULTS

A total of 130,145 patients underwent ERCP, 16,278 (12.5%) were readmitted within 30 days, with an associated cost of 268 million dollars. Nearly 40% of readmissions occurred within 7 days, and 47.9% were related to gastrointestinal etiologies. Male gender, increased comorbidities, cirrhosis, Medicare insurance, and pancreatitis or pancreatitis-related indications for ERCP were readmission risk factors. Performance of cholecystectomy on index hospitalization decreased odds of readmission by 50% (adjusted odds ratio: 0.48, 95% confidence interval: 0.45-0.52,P<0.0001). While academic and nonacademic centers had similar readmission rates, high ERCP volume centers had higher rates compared with low-volume centers (adjusted odds ratio:1.10,P=0.008).

CONCLUSION

All-cause 30-day readmission rates after inpatient ERCPs are high, mostly occur shortly postdischarge, and impose a heavy health care system burden. Large, multicenter prospective studies assessing the impact of center procedure volume on complications and readmission rates are needed.

Medicaid Payer Status Is a Predictor of Early Postoperative Pain Following Upper Extremity Procedures

Background: The purpose of this study was to investigate the relationship between insurance status and patient-reported pain both before and after upper extremity surgical procedures. We hypothesized that patients with Medicaid payer status would report higher levels of pre- and postoperative pain and report less postoperative pain relief. Methods: In all, 376 patients who underwent upper extremity procedures by a single surgeon at an academic ambulatory surgery center were identified. Patient information, including insurance status and Visual Analog Scale pain score (VAS-pain) at baseline, 2 weeks, and 1, 3, and 6 months, were collected. VAS-pain scores were compared with t-tests and linear regression. Results: Preoperatively and at 2-week, 1-month, and 3-month follow-up, Medicaid patients reported statistically significant higher pain levels than patients with Private insurance, finding a mean adjusted increase of 0.51 preoperatively, 0.39 at 1 month, and 0.79 at 3 months. Preoperatively and at 3-month follow-up, Medicaid patients reported statistically significant higher pain than patients with Medicare, finding increases in VAS-pain of 0.99 preoperatively and 0.94 at 3 months. There was no difference in pain improvement between any insurance types at any time point (all P values > .05). Conclusions: Patients with Medicaid report higher levels of preoperative pain and early postoperative pain, but reported the same improvement in pain as patients with other types of insurance. As healthcare systems are becoming increasingly dependent on patient-reported outcomes, including pain, it is important to consider that differences may exist in subjective pain depending on insurance status.

Association of Medicare and Medicaid Insurance Status with Increased Spine Surgery Utilization Rates

STUDY DESIGN

Retrospective single-institution study.

OBJECTIVE

The aim of this study was to determine the relationship between patients' insurance status and the likelihood for them to be recommended various spine interventions upon evaluation in our neurosurgical clinics.

SUMMARY OF BACKGROUND DATA

Socioeconomically disadvantaged populations have worse outcomes after spine surgery. No studies have looked at the differential rates of recommendation for surgery for patients presenting to spine surgeons based on socioeconomic status.

METHODS

We studied patients initially seeking spine care from spine-fellowship trained neurosurgeons at our institution from July 1, 2018 to June 30, 2019. Multivariable logistic regression was used to assess the association between insurance status and the recommended patient treatment.

RESULTS

Overall, 663 consecutive outpatients met inclusion criteria. Univariate analysis revealed a statistically significant association between insurance status and treatment recommendations for surgery (P < 0.001). Multivariate logistic regression demonstrated that compared with private insurance, Medicare (odds ratio [OR] 3.54, 95% confidence interval [CI] 1.21-7.53, P = 0.001) and Medicaid patients (OR 2.46, 95% CI 1.21-5.17, P = 0.014) were more likely to be recommended for surgery. Uninsured patients did not receive recommendations for surgery at significantly different rates than patients with private insurance.

CONCLUSION

Medicare and Medicaid patients are more likely to be recommended for spine surgery when initially seeking spine care from a neurosurgeon. These findings may stem from a number of factors, including differential severity of the patient's condition at presentation, disparities in access to care, and differences in shared decision making between surgeons and patients.Level of Evidence: 3.

Geographic disparities in performance of pediatric polysomnography to diagnose obstructive sleep apnea in a universal access health care system

BACKGROUND

Diagnostic polysomnography (PSG) is recommended prior to adenotonsillectomy (AT) for children with obstructive sleep apnea (OSA) and certain high-risk characteristics, but resource limitations often prevent this practice.

OBJECTIVE

We performed a population-based assessment of children across Ontario, Canada to describe and quantify disparities in PSG.

METHODS AND MATERIALS

This retrospective cohort study was performed using provincial health administrative data held at ICES. We identified children 0-10 years old who underwent PSG and AT between 2009 and 2018, and those with a PSG within 18 months prior to and/or 12 months following AT. We calculated the odds of PSG prior to/following AT after adjustment for demographics, medical comorbidities, geographic and socioeconomic characteristics. Our main predictor was driving time/distance to the nearest pediatric sleep centre ascertained using spatial analysis and geographic information systems.

RESULTS

We identified 27,837 children <10 years old who underwent AT for OSA in Ontario. Only 12.8% had a PSG within 18 months prior and 5.7% had a PSG within 12 months following AT. Shorter driving time/distance, older age, male sex and certain comorbidities were associated with increased odds of PSG.

CONCLUSION

Only a small proportion of children in our cohort underwent PSG prior to or following AT surgery despite universal access to healthcare. This study suggests a need to increase overall PSG access, particularly for those living distant from existing pediatric sleep centres. Future studies could determine if increased PSG testing in 'underserviced areas' would reduce overall surgery rates and/or improve health outcomes.

Association of hospital characteristics and insurance type with quality outcomes for pediatric craniosynostosis patients

OBJECTIVE

Our study aimed to assess the association of insurance status and hospital ownership type with inpatient hospital outcomes among a nationally representative population of pediatric craniosynostosis neurosurgery patients.

METHODS

This retrospective cohort study utilized data from the Healthcare Cost and Utilization Project 2006-2012 Kids Inpatient Database. Primary outcomes including length of stay, and favorable discharge disposition were assessed for all pediatric neurosurgery patients who underwent a neurosurgical procedure for craniosynostosis.

RESULTS

Pediatric neurosurgery patients with private insurance had a reduced length of stay of 0.75 days compared to patients insured by Medicaid. Compared to private, investor-owned hospitals, Government, non-federal, and private, not for profit hospital ownership types were associated with an increased length of stay greater than 1 day.

CONCLUSIONS

Our finding of increased LOS for craniosynostosis patients seen in other hospital ownership types compared to those seen in private, investor-owned hospitals is indicative of the possible role that financial incentives may play in influencing quality metrics. Although we observed a shortened LOS for privately-insured patients compared to patients insured by Medicaid, we found no difference in favorable discharge disposition based on insurance status. This suggests that patients with shorter LOS have similar outcomes and are likely not being prematurely discharged.

Comparison of Hirschsprung Disease Characteristics between Those with a History of Postoperative Enterocolitis and Those without: Results from the Pediatric Colorectal and Pelvic Learning Consortium

INTRODUCTION

 The current understanding of Hirschsprung-associated enterocolitis (HAEC) is based mainly on single-center, retrospective studies. The aims of this study are to determine risk factors for postoperative HAEC using the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC) database.

MATERIALS AND METHODS

 We performed a multicenter, retrospective, case-control study of children with Hirschsprung disease (HD) who had undergone a pull-through procedure and were evaluated at a PCPLC member site between February 2017 and March 2020. The cohort with a history of postoperative HAEC was compared with that without postoperative episodes of HAEC to determine relevant associations with postoperative HAEC.

RESULTS

 One-hundred forty of 299 (46.8%) patients enrolled had a history of postoperative HAEC. Patients with a rectosigmoid transition zone had a lower association with postoperative HAEC as compared with those with a more proximal transition zone (odds ratio [OR]: 0.46, 95% confidence interval [CI]: 0.26, 0.84, p < 0.01). Private insurance was protective against postoperative HAEC on univariate analysis (OR: 0.62, 95% CI: 0.38, 0.99, p = 0.047), but not on multivariate analysis (OR: 0.62, 95% CI: 0.37, 1.04, p = 0.07). Preoperative HAEC was not associated with the development of postoperative HAEC.

CONCLUSION

 Patients with a rectosigmoid transition zone have less postoperative HAEC compared with patients with a more proximal transition zone. Multi-institutional collection of clinical information in patients with HD may allow for the identification of additional risk factors for HAEC and afford the opportunity to improve care.

Insurance type impacts bronchoscopy for foreign body aspiration: An analysis of the Kids' Inpatient Database

OBJECTIVES

To ascertain whether insurance type is associated with postoperative adverse effects and hospital length of stay for inpatient airway foreign body removal.

METHODS

Retrospective analysis of children <18 years of age that underwent inpatient bronchoscopy with removal of airway foreign body in the national Healthcare Cost and Utilization Project Kid's Inpatient Database (KID). Postoperative outcomes and length of stay were analyzed for racial disparities and insurance type using multivariable logistic regression and negative binomial regression. Models adjusted for race, insurance type, sex, age, and presence of pulmonary risk factors.

RESULTS

A total of 5,850 children underwent bronchoscopy for foreign body removal. The median age was 2 (IQR: 4-1) years and 61.6% patients were male. Payer status included Medicaid (38.9%), private insurance (51.5%), self-pay (4.3%) and other (9.6%). The Medicaid cohort had a higher proportion of black (19.1%) and Hispanic patients (34.5%) (P < 0.001). Children covered under Medicaid had higher odds of postoperative complications (odds ratio [OR] 1.216; P = 0.031) and a greater length of stay (OR 1.533; P < 0.001) relative to the private insurance group when adjusting for sex, age, race and presence of pulmonary risk factors. The odds of having a greater length of stay was 33% higher for black (P < 0.001) and 37% higher for Hispanic (P < 0.001) children compared to white children. The average adjusted LOS under Medicaid was 8.37 days compared to 5.46 days for privately insured children.

CONCLUSION

This study demonstrated that a difference in postoperative complications and LOS exist between public and privately insured children for foreign body removal via bronchoscopy. Further studies are warranted to investigate factors that drive these disparities.

Early and late hospital readmissions after spine deformity surgery in children with cerebral palsy

STUDY DESIGN

Retrospective review of a prospectively collected multicenter registry of pediatric patients with cerebral palsy (CP) and neuromuscular scoliosis (NMS) undergoing spinal fusion.

OBJECTIVE

To define risk factors for unplanned readmission after elective spinal deformity surgery. Patients with CP and NMS have high rates of hospital readmission; however, risk factors for readmission are not well established.

METHODS

Univariate and multivariate analyses were used to compare the demographics, operative and postoperative course, radiographic characteristics, and preoperative Caregiver Priorities and Child Health Index of Life with Disabilities (CPCHILD) questionnaires of patients who did not require readmission to those who required either early readmission (within 90 days of the index surgery) or late readmission (readmission after 90 days).

RESULTS

Of the 218 patients identified, 19 (8.7%) required early readmission, while 16 (7.3%) required late readmission. Baseline characteristics were similar between the three cohorts. On univariate analysis, early readmission was associated with longer duration of surgery (p < 0.001) and larger magnitude of residual deformity (p = 0.003 and p = 0.029 for postoperative major and minor angles, respectively). The health score of the CPCHILD Questionnaire was lower in patients who required early readmission than in those who did not require readmission (p = 0.032). On multivariate analysis, oral feeding status was inversely related to early readmission (less likely to require readmission), while decreasing lumbar lordosis and increasing length of surgery were related to an increased likelihood of early readmission.

CONCLUSIONS

In patients with CP and NMS, longer surgical time, larger residual major and minor Cobb angles, lumbar lordosis, feeding status, and overall health may be related to a greater likelihood for early hospital readmission after elective spinal fusion. No factors were identified that correlated with an increased need for late hospital readmission after elective spinal fusion in patients with CP.

Comparing Standard Performance and Outcome Measures in Hospitalized Pituitary Tumor Patients with Secretory versus Nonsecretory Tumors

BACKGROUND

Patient safety indicators (PSIs) and hospital-acquired conditions (HACs) are reported quality measures. We compared their prevalence in patients with secretory and nonsecretory pituitary adenoma using the National (Nationwide) Inpatient Sample (NIS), Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality.

METHODS

The NIS was queried for hospitalizations 2002-2014 involving pituitary adenomas. Prevalence of PSI, HAC, and 9 pituitary-related complications was determined using International Classification of Diseases, Ninth Revision codes. Patient risk factors were evaluated through multivariate analysis.

RESULTS

A total of 20,743 patients with nonsecretory tumor and 3385 patients with secretory tumor were identified. Among patients with nonsecretory tumor, 3.79% experienced any PSI or HAC. Of patients with secretory tumor, 2.54% had any PSI or HAC. Before adjusting for covariation, secretory patients were less likely to have any PSI or HAC (odds ratio [OR], 0.652; P = 0.0002), experience any pituitary-related complication (OR, 0.804; P < 0.0001), have a poor outcome (hazard ratio [HR], 0.435; P < 0.0001), and die during hospitalization (HR, 0.293; P = 0.0015). Secretory patients had significantly shorter mean hospital length of stay (secretory/nonsecretory percent difference, -11.95%; P < 0.0001). However, inverse propensity score-weighted ORs comparing the groups' outcomes showed that there was no significant difference in the prevalence of any PSIs and HACs (OR, 0.963; P = 0.8570), pituitary-related complications (OR, 0.894; P = 0.1321), poor outcomes (HR, 0.990; P = 0.9287), in-hospital death (HR, 0.663; P = 0.2967), and length of stay (percent difference, -2.31%; P = 0.2967) between groups.

CONCLUSIONS

Lack of significant difference in outcome measures after controlling for covariation is consistent with our finding that patients with nonsecretory tumor have more comorbidities on presentation for treatment. PSIs and HACs have limited ability to measure complications specific to pituitary tumors.

Deriving literature-based benchmarks for pediatric appendectomy and cholecystectomy complications from national databases in high-income countries: A systematic review and meta-analysis

BACKGROUND

Health systems must identify preventable adverse outcomes to improve surgical safety. We conducted a systematic review to determine national rates of postoperative complications associated with two common pediatric surgery operations in High-Income Countries (HICs).

METHODS

National database studies of complication rates associated with pediatric appendectomies and cholecystectomies (2000-2016) in Canada, the US, and the UK were included. Outcomes included mortality, length of hospital stay (LOS), and other surgical complications. Outcome data were extracted and comparisons made between countries and databases.

RESULTS

Thirty-three papers met inclusion criteria (1 Canadian, 1 UK, and 4 US Databases). Mean LOS was 3.00 (±1.42) days and 3.44 (±1.55) days for appendectomy and cholecystectomy, respectively. Mortality was 0.06% after appendectomy and 0.24% after cholecystectomy. Readmission and reoperation rates were 6.79% and 0.32% for appendectomy, and 1.37% and 0.71% for cholecystectomy. For appendectomies, LOS was shorter in Canadian and UK studies compared to US studies, and mortality and readmission rates were lower (OR 0.46 95%CI 0.23 to 0.93, OR 3.63 to 3.77 95%CI) in UK studies compared to US studies.

CONCLUSIONS

Outcomes after pediatric appendectomy and cholecystectomy are good but vary between HICs. Understanding national outcomes and intercountry differences is essential in developing health system approaches to pediatric surgical safety.

Medicaid insurance status predicts postoperative mortality after total knee arthroplasty in state inpatient databases

Aim: Medicaid versus private primary insurance status may predict in-hospital mortality and morbidity after total knee arthroplasty (TKA). Materials & methods: Regression models were used to test our hypothesis in patients in the State Inpatient Database (SID) from five states who underwent primary TKA from January 2007 to December 2014. Results: Medicaid patients had greater odds of in-hospital mortality (odds ratio [OR]: 1.73; 95% CI: 1.01-2.95), greater odds of any postoperative complications (OR: 1.25; 95% CI: 1.18-1.33), experience longer lengths of stay (OR: 1.09; 95% CI: 1.08-1.10) and higher total charges (OR: 1.03; 95% CI: 1.02-1.04). Conclusion: Medicaid insurance status is associated with higher in-hospital mortality and morbidity in patients after TKA compared with private insurance.

Association of Health Care Utilization With Rates of Perforated Appendicitis in Children 18 Years or Younger

Importance

The pediatric perforated appendix rate is a quality metric measured by the Agency for Healthcare Research and Quality (AHRQ) that reflects access to care. The association of health care utilization prior to presentation with appendicitis is unknown.

Objective

To determine whether increased health care utilization prior to presentation with appendicitis is associated with lower perforated appendicitis rates in children.

Design, Setting, and Participants

Retrospective cohort study of privately insured children drawn from large employer and insurance company administrative data found in the Truven MarketScan national insurance claims database. Cases of appendicitis were identified among 38 348 children 18 years or younger from January 1, 2010, through December 31, 2013, with corresponding primary health care encounters from January 1, 2009, through December 31, 2012. In all, 19 109 eligible children were identified using International Classification of Diseases, Ninth Revision (ICD-9) diagnosis codes for appendicitis after excluding those patients who did not have continuous insurance coverage during the study period. Statistical analysis was performed from September 1, 2016, to October 15, 2017.

Exposures

Health care utilization was determined by the number of outpatient clinic encounters for each patient in the 1 to 12 months before presentation with appendicitis.

Main Outcomes and Measures

Perforated appendicitis was defined according to the AHRQ by using ICD-9 codes for perforation and hospital length of stay of 3 or more days. Logistic regression models were used for perforated appendicitis after adjustment for age, sex, income, gastrointestinal comorbidities, geographic region, and insurance type.

Results

We identified 38 348 children 18 years or younger with ICD-9 diagnosis codes for appendicitis, and 19 109 children remained for analysis after applying exclusion criteria. Of these, 11 422 were boys (59.8%); the mean (SD) age was 12.4 (3.9) years. Of the 19 109 children identified who underwent appendectomy, 5509 (28.8%) presented with perforated appendicitis. Children with perforation had lower outpatient health care utilization in the year before presentation compared with those diagnosed with acute appendicitis (4554 of 5509 children [82.7%] vs 11 937 of 13 600 [87.8%]; P < .001). In the adjusted model, outpatient health care utilization before presentation was associated with lower odds of perforated appendicitis (odds ratio [OR], 0.63; 95% CI, 0.58-0.69; P < .001). This association increased with visit frequency in the year before presentation (OR, 0.86; 95% CI, 0.77-0.95 for 1-2 visits, P = .003; OR, 0.61; 95% CI, 0.55-0.67 for 3-6 visits, P < .001; and OR, 0.43; 95% CI, 0.38-0.48 for ≥7 visits [5-18 years], P < .001). Covariates associated with perforation included younger age, geographic region, family income, and higher out-of-pocket insurance plans.

Conclusions and Relevance

Among insured children 18 years or younger, increased health care utilization was associated with lower rates of perforated appendicitis. Primary health care relationships may facilitate timely presentation or serve as a marker for health-related self-efficacy, thereby contributing to outcomes for acute surgical conditions.

Payer and race/ethnicity influence length and cost of childhood cancer hospitalizations

BACKGROUND

Health disparities related to race, ethnicity, socioeconomic status, and insurance status impact quality, access, and health outcomes for children. Medicaid is a proxy for poverty and restricted access to health care. The goal of this study was to determine if there are discrepancies in the length and cost of hospitalizations between admissions covered by Medicaid or commercial insurance for pediatric patients with cancer.

METHODS

Childhood cancer-related admissions were identified from the 2012 Kids Inpatient Database (KID) using the International Classification of Diseases, Ninth revision. Length of hospitalization and cost of hospitalization were compared among hospitalizations paid by Medicaid or commercial insurance. Total admission charges were converted to costs using cost-to-charge ratios, and survey weighting methods were used for all analyses. Linear multiple regression models for both length of hospitalization and cost were developed to include patient-level factors (race, sex, age, diagnosis, reason for admission).

RESULTS

In 2012, there were 104 597 childhood cancer-related admissions. Hospitalizations paid by Medicaid were significantly longer than those paid by commercial insurance. Hispanic ethnicity was associated with higher cost of hospitalization regardless of payer, and black race was associated with higher costs within the Medicaid population.

CONCLUSIONS

This analysis identifies differences in healthcare utilization for pediatric cancer-related admissions paid for by Medicaid compared with commercial insurance. Prolonged hospitalizations and increased costs create burdens on children and their families, medical delivery systems, and third-party payers. Further exploration into the causes of these disparities is warranted.

Insurance Payer Type and Patient Income Are Associated with Outcomes after Total Shoulder Arthroplasty

OBJECTIVE

To assess the independent association of insurance and patient income with total shoulder arthroplasty (TSA) outcomes.

METHODS

We used the 1998-2014 US National Inpatient Sample. We used multivariable-adjusted logistic regression to examine whether insurance type and the patient's median household income (based on postal code) were independently associated with healthcare use (discharge destination, hospital stay duration, total hospital charges) and in-hospital complications post-TSA based on the diagnostic codes (fracture, infection, transfusion, or revision surgery). We calculated the OR and 95% CI.

RESULTS

Among the 349,046 projected TSA hospitalizations, the mean age was 68.6 years, 54% were female, and 73% white. Compared to private insurance, Medicaid and Medicare (government insurance) users were associated with significantly higher adjusted OR (95% CI) of (1) discharge to a rehabilitation facility, 2.16 (1.72-2.70) and 2.27 (2.04-2.52); (2) hospital stay > 2 days, 1.65 (1.45-1.87) and 1.60 (1.52-1.69); and (3) transfusion, 1.35 (1.05-1.75) and 1.39 (1.24-1.56), respectively. Medicaid was associated with a higher risk of fracture [1.74 (1.07-2.84)] and Medicare user with a higher risk of infection [2.63 (1.24-5.57)]; neither were associated with revision. Compared to the highest income quartile, the lowest income quartile was significantly associated with (OR, 95% CI): (1) discharge to a rehabilitation facility (0.89, 0.83-0.96); (2) hospital stay > 2 days (0.84, 0.80-0.89); (3) hospital charges above the median (1.19, 1.14-1.25); (4) transfusion (0.73, 0.66-0.81); and (5) revision (0.49, 0.30-0.80), but not infection or fracture.

CONCLUSION

This information can help to risk-stratify patients post-TSA. Future assessments of modifiable mediators of these complications are needed.

Payer type does not impact patient-reported outcomes after primary total knee arthroplasty

Background

There is a paucity of literature assessing whether payer type has an impact on postoperative patient-reported outcomes (PROs) after total knee arthroplasty (TKA). The aim of this study was to comparatively evaluate TKA PROs among patients with commercial and Medicare insurance.

Methods

We conducted a single-center, retrospective review of patients operated between January 2017 and March 2018. Knee Disability and Osteoarthritis Outcome Score Junior (KOOS-Jr) and Veterans RAND 12 Health Survey (VR-12) Physical Component (VR-12 PCS) and Mental Component (VR-12 MCS) PRO scores were collected prospectively at baseline and 12 weeks postoperatively via an electronic patient rehabilitation application. Univariable and multivariable linear regressions were utilized to assess the effects of patient insurance type on PRO.

Results

In total, 193 TKA candidates had commercial (n = 91) or Medicare (n = 102) as their primary payer type. Demographic variables including age, gender, body mass index, and race varied significantly between the cohorts (P < .05). Length of stay and discharge disposition also varied significantly (P < .05). When compared with commercial payers, Medicare beneficiaries demonstrated a 4.13 ± 2.06 increase in Knee Disability and Osteoarthritis Outcome Score JR. scores at baseline (P < .05). However, after adjusting for patient-specific demographic and perioperative variables, all PROs recorded in this study were similar between the 2 payer groups at baseline and 12 weeks postoperatively (P > .05). Furthermore, ΔPRO scores from baseline to 12 weeks were also similar (P > .05).

Conclusions

After adjusting for patient-specific variables, PROs are similar at baseline and 12 weeks postoperatively between commercial and Medicare cohorts. For TKA candidates with similar baseline demographics, surgeons can expect similar perioperative PROs regardless of insurance type.

Medicaid Payer Status Is Associated with Increased 90-Day Morbidity and Resource Utilization Following Primary Total Hip Arthroplasty: A Propensity-Score-Matched Analysis

BACKGROUND

Medicaid payer status has been shown to affect risk-adjusted outcomes and resource utilization across multiple medical specialties. The purpose of this study was to examine resource utilization via readmission rates, length of stay, and total cost specific to Medicaid payer status following primary total hip arthroplasty.

METHODS

The Nationwide Readmissions Database (NRD) was utilized to identify patients who underwent total hip arthroplasty in 2013 as well as corresponding "Medicaid" or "non-Medicaid" payer status. Demographic data, 14 individual comorbidities, readmission rates, length of stay, and direct cost were evaluated. A propensity-score-based matching model was utilized to control for baseline confounding variables between payer groups. Following propensity-score matching, the chi-square test was used to compare readmission rates between the 2 payer groups. The relative risk (RR) with 95% confidence interval (CI) was estimated to quantify readmission risk. Length of stay and total cost comparisons were evaluated using the Wilcoxon signed-rank test.

RESULTS

A total of 5,311 Medicaid and 144,814 non-Medicaid patients managed with total hip arthroplasty were identified from the 2013 NRD. A propensity score was estimated for each patient on the basis of the available baseline demographics, and 5,311 non-Medicaid patients were matched by propensity score to the 5,311 Medicaid patients. Medicaid versus non-Medicaid payer status yielded significant differences in overall readmission rates of 28.8% versus 21.0% (p < 0.001; RR = 1.37 [95% CI, 1.28 to 1.46]) and 90-day hip-specific readmission rates of 2.5% versus 1.8% (p = 0.01; RR = 1.38 [95% CI, 1.07 to 1.78]). Mean length of stay was greater in the Medicaid group than in the non-Medicaid group at 4.5 versus 3.3 days (p < 0.0001), as was the mean total cost at $71,110 versus $65,309 (p < 0.0001).

CONCLUSIONS

This study demonstrates that Medicaid payer status is independently associated with increased resource utilization, including readmission rates, length of stay, and total cost following primary total hip arthroplasty. Providers may have a disincentive to treat patient populations who require increased resource utilization following surgery. Risk adjustment models accounting for Medicaid payer status are necessary to avoid decreased access to care for this patient population and to avoid financial penalty for physicians and hospitals alike.

Community-Based Health Insurance Increased Health Care Utilization and Reduced Mortality in Children Under-5, Around Bwindi Community Hospital, Uganda Between 2015 and 2017

Introduction: Out-of-pocket fees to pay for health care prevent poor people from accessing health care and drives millions into poverty every year. This obstructs progress toward the World Health Organization goal of universal health care. Community-based health insurance (CBHI) improves access to health care primarily by reducing the financial risk. The association of CBHI with reduced under-5 mortality was apparent in some voluntary schemes. This study evaluated the impact of eQuality Health Bwindi CBHI scheme on health care utilization and under-5 mortality in rural south-western Uganda. Methods: This was a retrospective cross-sectional study using routine electronic data on health insurance status, health care utilization, place of birth, and deaths for children aged under-5 in the catchment area of Bwindi Community Hospital, Uganda between January 2015 and June 2017. Data was extracted from four electronic databases and cross matched. To assess the association with health insurance, we measured the difference between those with and without insurance; in terms of being born in a health facility, outpatient attendance, inpatient admissions, length of stay and mortality. Associations were assessed by Chi-Square tests with p-values < 0.05 and 95% confidence intervals. For variables found to be significant at this level, multivariable logistic regression was done to control for possible confounders. Results: Of the 16,464 children aged under-5 evaluated between January 2015 and June 2017, 10% were insured all of the time 19% were insured for part of the period, and 71% were never insured. Ever having had health insurance reduced the risk of death by 36% [aOR; 0.64, p = 0.009]. While children were insured, they visited outpatients ten times more, and were four times more likely to be admitted. If admitted, they had a significantly shorter length of stay. If mother was uninsured, children were less likely to be born in a health facility [adjusted odds ratio (aOR) 2.82, p < 0.001]. Conclusion: This study demonstrated that voluntary CBHI increased health care utilization and reduced mortality for children under-5. But the scheme required appreciable outside subsidy, which limits its wider application and replicability. While CBHIs can contribute to progress toward Universal Health Care they cannot always be afforded.

Health Care Access Barriers Bring Children to Emergency Rooms More Frequently: A Representative Survey

Children may visit the emergency department (ED) regularly in part because they and their caregivers may be experiencing barriers to appropriate and timely pediatric care. However, assessing the wide range of potential barriers to access to care that children and their caregivers may experience is often a challenge. The objective of this study was to assess the barriers to pediatric health care reported by caregivers and to examine the association between those reported barriers to care with the frequency of children's ED visits in the past 12 months. Assessment of ED utilization and access to care barriers was made through a telephone interview survey conducted as part of a broader Community Health Needs Assessment in 2015. A weighted community sample of adult caregivers (N = 1057) of children between the ages of 0-17 residing in Miami-Dade, Broward, and Palm Beach counties, Florida were contacted. This study found that multiple ED visits (≥2 vs. 0) in the past 12 months by a child were most strongly associated with access to care barriers attributed to language and culture (relative risk [RR] = 2.51), trouble finding a doctor (RR = 1.86), scheduling an appointment (RR = 1.68), and transportation access (RR = 1.73). These findings suggest that access to care barriers experienced by households may exacerbate the risk of a child experiencing repeated visits to the ED in a year. Findings are discussed further in the context of actionable population health management strategies to reduce risk of frequent ED utilization by children.

Ten-year outcomes of Roux-en-Y gastric bypass are equivalent in patients with Medicare disability and non-Medicare patients

BACKGROUND

Bariatric surgery is the most effective intervention for achieving durable weight loss and improvement of comorbidities in patients with obesity. Limited data exist on the impact of Medicare status in patients undergoing Roux-en-Y gastric bypass. We hypothesized that there is no difference in outcomes between Medicare beneficiaries and non-Medicare patients at the 10-year follow-up.

METHODS

All patients who underwent Roux-en-Y gastric bypass with 10-year follow-up at a single medical center from 1985 to 2005 were stratified by Medicare insurance status. Outcomes included 10-year percent reduction in excess body mass index and comorbidity resolution.

RESULTS

Of 617 patients who underwent Roux-en-Y gastric bypass with 10-year follow-up, 117 (19%) were insured under Medicare. Medicare patients were older (43 vs 40 years, P = .01) and had a greater preoperative body mass index (53.2 vs 51.0 kg/m², P = .03) than non-Medicare patients, but there were no differences in preoperative median comorbidity index scores (3 [interquartile range 1-4] vs 2 [interquartile range 1-5], P = .33). At 10 years, weight loss (58.3% vs 57.0 percent reduction in excess body mass index, P = .16) and the decrease in median comorbidity index (1 [interquartile range 0-3] vs 1 [interquartile range 0-3], P = .85) were equivalent between groups.

CONCLUSIONS

Roux-en-Y gastric bypass is equally beneficial in Medicare Disability and non-Medicare patients at 10 years. These findings support the continued and expanded coverage of bariatric surgery operations by Medicare.

Payer Source Associated with Disparities in Procedural, but Not Surgical, Care in a Trauma Population

Trauma centers are legally bound by Emergency Medical Treatment and Active Labor Act to provide equal treatment to trauma patients, regardless of payer source. However, evidence has suggested that disparities in trauma care exist. This study investigated the relationships between payer source and procedures (total, diagnostic, and surgical) and the number of medical consults in an adult trauma population. This is a 10-year retrospective trauma registry study at a Level I trauma facility. Payer source of adult trauma patients was identified, demographics and variables associated with trauma outcomes were abstracted, and multivariate logistic regression tests were used to determine statistical differences in the number of procedures and medical consults. Of the 12,870 records analyzed, 69.1 per cent of patients were commercially insured, 21.2 per cent were uninsured, and 9.6 per cent had Medicaid. After controlling for patient- and injury-related variables, the commercially insured received more total procedures (4.30) than the uninsured (3.35) or those with Medicaid (3.34), and more diagnostic (2.59) procedures than the uninsured (2.03) or those with Medicaid (2.04). There was not a difference in the number of surgical procedures or medical consults among payer sources. This study noted that disparities (measured by the number of procedures received) compared by payer source existed in the care of trauma patients. However, for medical consults and definitive care (measured by surgical procedures), disparities were not observed. Future research should focus on secondary factors that influence levels of care such as patient-level factors (health literacy) and trauma program policies.

Medicaid is associated with increased readmission and resource utilization after primary total knee arthroplasty: a propensity score-matched analysis

Background

Medicaid payer status has been shown to affect resource utilization across multiple medical specialties. There is no large database assessment of Medicaid and resource utilization in primary total knee arthroplasty (TKA), which this study sets out to achieve.

Methods

The Nationwide Readmissions Database was used to identify patients who underwent TKA in 2013 and corresponding “Medicaid” or “non-Medicaid” payer statuses. Demographics, 15 individual comorbidities, readmission rates, length of stay, and direct cost were evaluated. A propensity score–based matching model was then used to control for baseline confounding variables between payer groups. A chi-square test for paired proportions was used to compare readmission rates between the 2 groups. Length of stay and direct cost comparisons were evaluated using the Wilcoxon signed-rank test.

Results

A total of 8372 Medicaid and 268,261 non-Medicaid TKA patients were identified from the 2013 Nationwide Readmissions Database. A propensity score was estimated for each patient based on the baseline demographics, and 8372 non-Medicaid patients were propensity score matched to the 8372 Medicaid patients. Medicaid payer status yielded a statistically significant increase in overall readmission rates of 18.4% vs 14.0% (P < .0001, relative risk = 1.31, 95% confidence interval [1.23-1.41]) with non-Medicaid status and 90-day readmission rates of 10.0% vs 7.4%, respectively (P < .001, relative risk = 1.35, 95% confidence interval [1.22-1.48]). The mean length of stay was longer in the Medicaid group compared with the non-Medicaid group at 4.0 days vs 3.3 days (P < .0001) as well as the mean total cost of $64,487 vs $61,021 (P < .0001).

Conclusions

This study demonstrates that Medicaid payer status is independently associated with increased resource utilization, including readmission rates, length of stay, and total cost after TKA.

Insurance Coverage and Acute Care Revisits After Pediatric Ambulatory Tonsillectomy

We investigated whether patterns of health insurance coverage were associated with 30-day all-cause acute care revisits after ambulatory tonsillectomy at a free-standing quaternary-care pediatric hospital. Insurance patterns were classified from past encounters as continuous private, continuous Medicaid, Medicaid-to-private change, or private-to-Medicaid change. Among 478/675 boys/girls (age 9 ± 4 years) selected for analysis, 148 (13%) had 30-day revisits, whereas 96 (8%) changed from Medicaid to private insurance, and 99 (9%) changed from private insurance to Medicaid. Revisits were most common in the private-to-Medicaid group, compared with continuous private coverage (19% vs 10%; 95% CI of difference: 1%-18%; P = .007). The private-to-Medicaid group was most likely to be overweight, have symptoms of sleep disordered breathing, and have more past clinical encounters. In multivariable analysis, the greater risk of acute care revisits among children with private-to-Medicaid change in coverage was attributable to greater comorbidity burden and past health care utilization.

Impaired growth outcomes in children with congenital colorectal diseases

BACKGROUND

Cloaca, Hirschsprung disease, and anorectal malformations (CHARM) are congenital anomalies of the hindgut. Small series have suggested that children suffering from one of these anomalies may be at risk for growth impairment. We sought to expand on these findings in a comprehensive cohort, hypothesizing that patients with Medicaid insurance or African-American (AA) race would be at higher risk for poor growth.

METHODS

Following Institutional Review Board (IRB) approval, single-institution retrospective review of children with CHARM anomalies was performed (2009-2016). Body mass index (BMI) value Z-scores were obtained using the 2006 World Health Organization (age 0-24 mo) and 2000 Centers for Disease Control (CDC) (age >2 y) growth charts and calculators (statistical analysis system). Patient factors and BMI Z-scores were analyzed with descriptive statistics and Fisher's exact test.

RESULTS

One hundred sixty-six patients (Cloaca n = 16, Hirschsprung disease [HD] n = 71, anorectal malformation [ARM] n = 79) were identified. The BMI Z-score distribution for the entire CHARM cohort was lower than controls (P < 0.0001). HD and ARM BMI Z-scores were also lower versus controls (P < 0.0007, P < 0.0037). Requiring more or less than the average number of surgeries did not impact BMI Z-score [P = non-significant (NS)]. Patients with Medicaid had lower Z-scores versus private or commercial insurance (P < 0.0001). AA race BMI Z-score distribution was lower than controls (P < 0.0002), but there was no statistical difference in BMI Z-scores when comparing AA versus non-AA CHARM patients (P = NS).

CONCLUSIONS

Patients born with CHARM anomalies are at risk for impaired growth. Furthermore study is warranted to identify modifiable risk factors contributing to this impairment. Longitudinal follow-up should include interventions to mitigate these risks.

Coronary artery bypass graft readmission rates and risk factors - A retrospective cohort study

BACKGROUND

Hospital readmissions contribute substantially to the overall healthcare cost. Coronary artery bypass graft (CABG) is of particular interest due to its relatively high short-term readmission rates and mean hospital charges.

METHODS

A retrospective review was performed on 2007-2011 data from California, Florida, and New York from the State Inpatient Databases, Healthcare Cost and Utilization Project. All patients ≥18 years of age who underwent isolated CABG and met inclusion/exclusion criteria were included. Insurance status was categorized by Medicaid, Medicare, Private Insurance, Uninsured, and Other. Primary outcomes were unadjusted rates and adjusted odds of readmission at 30- and 90-days. Secondary outcomes included diagnosis at readmission.

RESULTS

A total of 177,229 were included in the analyses after assessing for exclusion criteria. Overall 30-day readmission rate was 16.1%; rates were highest within Medicare (18.4%) and Medicaid (20.2%) groups and lowest in the private insurance group (11.7%; p < 0.0001). Similarly, 90-day rates were highest in Medicare (27.3%) and Medicaid (29.8%) groups and lowest in the private insurance group (17.6%), with an overall 90-day rate of 24.0% (p < 0.0001). The most common 30-day readmission diagnoses were atrial fibrillation (26.7%), pleural effusion (22.5%), and wound infection (17.7%). Medicare patients had the highest proportion of readmissions with atrial fibrillation (31.7%) and pleural effusions (23.3%), while Medicaid patients had the highest proportion of readmissions with wound infections (21.8%). Similar results were found at 90 days. Risk factors for readmission included non-private insurance, age, female sex, non-white race, low median household income, non-routine discharge, length of stay, and certain comorbidities and complications.

CONCLUSIONS

CABG readmission rates remain high and are associated with insurance status and racial and socioeconomic markers. Further investigation is necessary to better delineate the underlying factors that relate racial and socioeconomic disparities to CABG readmissions. Understanding these factors will be key to improving healthcare outcomes and expenditure.

Association between Socioeconomic Status and 30-Day and One-Year All-Cause Mortality after Surgery in South Korea

Preoperative socioeconomic status (SES) is associated with outcomes after surgery, although the effect on mortality may vary according to region. This retrospective study evaluated patients who underwent elective surgery at a tertiary hospital from 2011 to 2015 in South Korea. Preoperative SES factors (education, religion, marital status, and occupation) were evaluated for their association with 30-day and one-year all-cause mortality. The final analysis included 80,969 patients who were ≥30 years old, with 30-day mortality detected in 339 cases (0.4%) and one-year mortality detected in 2687 cases (3.3%). As compared to never-married patients, those who were married or cohabitating (odds ratio (OR): 0.678, 95% confidence interval (CI): 0.462–0.995) and those divorced or separated (OR: 0.573, 95% CI: 0.359–0.917) had a lower risk of 30-day mortality after surgery. Similarly, the risk of one-year mortality after surgery was lower among married or cohabitating patients (OR: 0.857, 95% CI: 0.746–0.983) than it was for those who had never married. Moreover, as compared to nonreligious patients, Protestant patients had a decreased risk of 30-day mortality after surgery (OR: 0.642, 95% CI: 0.476–0.866). The present study revealed that marital status and religious affiliation are associated with risk of 30-day and one-year all-cause mortality after surgery.

Does Payer Type Influence Pediatric Burn Outcomes? A National Study Using the Healthcare Cost and Utilization Project Kids' Inpatient Database

Pediatric burns are a considerable source of injury in the United States. Socioeconomic status has been demonstrated to influence other disease outcomes. The goal of this study was to analyze national pediatric burn outcomes based on payer type. A retrospective study was designed using the Kids' Inpatient Database (KID), years 2000 to 2009. Patients 18 years of age and under with Major Diagnostic code number 22 for burn were included. A total of 22,965 patients were identified, estimating 37,856 discharges. Descriptive and bivariate statistics were performed. Multiple regression analysis was used to assess correlation of payer type with complications and length of stay (LOS). The majority of patients were Medicaid (52.3%). Medicaid patients were younger (4.25, P < .05), had a higher rate of being in the first quartile of their zipcode's income (46.26%, P < .05), and contained a higher proportion of African-Americans (30.01%, P < .05). Overall complication rate was higher among Medicaid patients than private insurance and self-pay patients (6.64 vs 5.51 and 4.35%, respectively, P = .11). Logistic regression analysis of complications showed that Medicaid coverage (P < .001) was associated with complications. The geometric mean LOS among Medicaid patients was 3.7 days compared with private insurance (3.5 days) and self-pay patients (3.1 days). Medicaid patients had longer LOS and more complications. Regression analysis revealed that payer type was a factor in LOS and overall complication rate. Identifying dissimilar outcomes based on patient and injury characteristics is critical in providing information on how to improve those outcomes.

The Risks of Hepatitis C in Association With Cervical Spinal Surgery: Analysis of Radiculopathy and Myelopathy Patients

STUDY DESIGN

Retrospective review.

OBJECTIVE

To investigate rates of in-hospital postsurgical complications among hepatitis C-infected patients after cervical spinal surgery in comparison with uninfected patients and determine independent risk factors.

SUMMARY OF BACKGROUND DATA

Studying hepatitis C virus (HCV) as a possible risk factor for cervical spine postoperative complications is prudent, given the high prevalence of cervical spondylosis and HCV in older patients. Spine literature is limited with respect to the impact of chronic HCV upon complications after surgery.

MATERIALS AND METHODS

Patients who underwent cervical spine surgery for cervical radiculopathy (CR) or cervical myelopathy (CM) from 2005 to 2013 were retrospectively reviewed using the Nationwide Inpatient Sample database. Patients were divided into CR and CM groups, with comparative subgroup analysis of HCV and no-HCV patients. Univariate analysis compared demographics and complications. Binary logistic stepwise regression modeling identified any independent outcome predictors (covariates: age, sex, Deyo score, and surgical approach).

RESULTS

In total, 227,310 patients (HCV: n=2542; no-HCV: n=224,764) were included. From 2005 to 2013, HCV infection prevalence among all cervical spinal fusion cases increased from 0.8% to 1.2%. HCV patients were more likely to be African American or Hispanic and have Medicare and/or Medicaid (all P<0.001). Overall complication rates among HCV patients with CR or CM increased, specifically related to device (CR: 3.1% vs. 1.9%; CM: 2.9% vs. 1.3%), hematoma/seroma (CR: 1.1% vs. 0.4%; CM: 1.8% vs. 0.8%), and sepsis (CR: 0.4% vs. 0.1%; CM: 1.1% vs. 0.5%) (all P≤0.001). Among CR and CM patients, HCV significantly predicted increased complication rates [odds ratio (OR): 1.268; OR: 1.194], hospital stay (OR: 1.738; OR: 1.861), and hospital charges (OR: 1.516; OR: 1.732; all P≤0.044).

CONCLUSIONS

HCV patients undergoing cervical spinal surgery were found to have increased risks of postoperative complications and increased risk associated with surgical approach. These findings should augment preoperative risk stratification and counseling for HCV patients and their spine surgeons.

Insurance Type and Major Complications After Hysterectomy

OBJECTIVES

The aim of this study was to investigate the relationship between primary insurance type and major complications after hysterectomy.

METHODS

A retrospective analysis was performed on women with Medicaid, Medicare, and private insurance who underwent hysterectomy from January 1, 2012, to July 1, 2014, and were included in the Michigan Surgical Quality Collaborative. Major complications within 30 days of surgery included the following: deep/organ space surgical site infection, deep venous and pulmonary thromboembolism, myocardial infarction or stroke, pneumonia or sepsis, blood transfusion, readmission, and death. Multivariable logistic regression was used to identify factors associated with major complications and characteristics associated with the Medicaid and Medicare groups.

RESULTS

A total of 1577 women had Medicaid, 2103 had Medicare, and 11,611 had private insurance. The Medicaid and Medicare groups had a similar rate of major complications, nearly double that of the private insurance group (6.85% vs 7.85% vs 3.79%; P < .001). Compared with private insurance, women with Medicaid and Medicare had increased odds of major complications (Medicaid: odds ratio [OR], 1.60; 95% confidence interval [CI], 1.26-2.04; P < .001; Medicare: OR, 1.34; 95% CI, 1.04-1.73; P = .03). Women with Medicaid were more likely to be nonwhite, have a higher body mass index (BMI), report tobacco use in the last year and undergo an abdominal hysterectomy. Those with Medicare were more likely to be white, to have gynecologic cancer, and to be functionally dependent. Both groups had increased odds of American Society of Anesthesiology class 3 or higher and decreased odds of undergoing hysterectomy at large hospitals (≥500 beds).

CONCLUSIONS

Women with Medicaid and Medicare insurance have increased odds of major complications after hysterectomy. Abdominal hysterectomy, BMI, and smoking are potentially modifiable risk factors for women with Medicaid.

Insurance status, mortality, and hospital use among pediatric trauma patients over three decades

BACKGROUND

We investigated the association between lack of insurance and mortality, resource use, and medical comorbidities among pediatric trauma patients.

METHODS

Our trauma database was queried for patients <18 years old from 1989 through 2013. Data collected included demographics, injury severity score (ISS), and insurance status. Dependent variables included major medical comorbidities, hospital and ICU lengths of stay (LOS), and mortality. Logistic regression and tests of equivalence were used to analyze the data.

RESULTS

A total of 3120 patients were included. The mortality among patients with insurance was 3.6% compared to 8.4% among those without insurance (p=0.0001, OR =2.42, 95% CI=1.53-3.82). This relationship remained statistically significant with adjustment via multivariable logistic regression (p=0.0001, OR =2.83, 95% CI: 1.64-4.74). Hospital and ICU LOS were significantly greater among insured patients in severely and moderately injured samples, respectively. There was no correlation between insurance and medical comorbidities. The uninsured mortality rate was 12.9% from 1989 to 1997 compared to 3.9% in 2006-2013.

CONCLUSION

Lack of insurance was associated with mortality but not preexisting comorbidity. This relationship persisted over time despite an overall decline in mortality. Additionally, lack of insurance was associated with decreased hospital stay and ICU utilization.

Medicaid insurance as primary payer predicts increased mortality after total hip replacement in the state inpatient databases of California, Florida and New York

STUDY OBJECTIVE

To confirm the relationship between primary payer status as a predictor of increased perioperative risks and post-operative outcomes after total hip replacements.

DESIGN

Retrospective cohort study.

SETTING

Administrative database study using 2007-2011 data from California, Florida, and New York from the State Inpatient Databases (SID), Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality.

PATIENTS

295,572 patients age≥18years old who underwent total hip replacement with non-missing insurance data were collected, using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnoses and procedures code (ICD-9-CM code 81.51).

INTERVENTIONS

Patients underwent total hip replacement.

MEASUREMENTS

Patients were cohorted by insurance type as either Medicare, Medicaid, Uninsured, Other, and Private Insurance. Demographic characteristics and comorbidities were compared. Unadjusted rates of in-hospital mortality, postoperative complications, LOS, 30-day, and 90-day readmission status were compared. Adjusted odds ratios were calculated for our outcomes using multivariate linear and logistic regression models fitted to our data.

MAIN RESULTS

Medicaid patients incurred a 125% increase in the odds of in-hospital mortality compared to those with Private Insurance (OR 2.25, 99% CI 1.01-5.01). Medicaid payer status was associated with the highest statistically significant adjusted odds of mortality, any complication (OR, 1.26), cardiovascular complications (OR, 1.37), and infectious complications (OR, 1.66) when compared with Private Insurance. Medicaid patients had the highest statistically significant adjusted odds of 30-day (OR, 1.63) and 90-day readmission (OR, 1.58) and the longest adjusted LOS.

CONCLUSIONS

We found higher unadjusted rates and risk adjusted odds ratios of postoperative mortality, morbidity, LOS, and readmissions for patients with Medicaid insurance as compared to patients with Private Insurance. Our study shows that primary payer status serves as a predictor of perioperative risks and that primary payer status should be viewed as a peri-operative risk factor.

National Incidence of Patient Safety Indicators in the Total Hip Arthroplasty Population

BACKGROUND

The Centers for Medicare & Medicaid Services use the incidence of patient safety indicators (PSIs) to determine health care value and hospital reimbursement. The national incidence of PSI has not been quantified in the total hip arthroplasty (THA) population, and it is unknown if patient insurance status is associated with PSI incidence after THA.

METHODS

All patients in the Nationwide Inpatient Sample (NIS) who underwent THA in 2013 were identified using the International Classification of Diseases, Ninth Revision, Clinical Modification codes. The incidence of PSI was determined using the International Classification of Diseases, Ninth Revision, diagnosis code algorithms published by the Centers for Medicare & Medicaid Services and the Agency for Healthcare Research and Quality. The association of insurance status and the incidence of PSI during the inpatient episode was determined by comparing privately insured and Medicare patients with Medicaid/self-pay patients using a logistic regression model that controlled for patient demographics, patient comorbidities, and hospital characteristics.

RESULTS

In 2013, the NIS included 68,644 hospitalizations with primary THA performed during the inpatient episode. During this period, 429 surgically relevant PSI were recorded in the NIS. The estimated national incidence rate of PSI after primary THA was 0.63%. In our secondary analysis, the privately insured cohort had significantly lower odds of experiencing one or more PSIs relative to the Medicaid/self-pay cohort (odds ratio, 0.47; 95% confidence interval, 0.29-0.76).

CONCLUSION

The national incidence of PSI among THA patients is relatively low. However, primary insurance status is associated with the incidence of one or more PSIs after THA. As value-based payment becomes more widely adopted in the United States, quality benchmarks and penalty thresholds need to account for these differences in risk-adjustment models to promote and maintain access to care in the underinsured population.

The effect of gun control laws on hospital admissions for children in the United States

BACKGROUND

Gun control laws vary greatly between states within the United States. We hypothesized that states with strict gun laws have lower mortality and resource utilization rates from pediatric firearms-related injury admissions.

METHODS

Kids' Inpatient Database (1997-2012) was searched for accidental (E922), self-inflicted (E955), assault (E965), legal intervention-related (E970), or undetermined circumstance (E985) firearm injuries. Patients were younger than 20 years and admitted for their injuries. Case incidence trends were examined for the study period. Propensity score-matched analyses were performed using 38 covariates to compare outcomes between states with strict or lenient gun control laws.

RESULTS

Overall, 38,424 cases were identified, with an overall mortality of 7%. Firearm injuries were most commonly assault (64%), followed by accidental (25%), undetermined circumstance (7%), or self-inflicted (3%). A small minority involved military-grade weapons (0.2%). Most cases occurred in lenient gun control states (48%), followed by strict (47%) and neutral (6%).On 1:1 propensity score-matched analysis, in-hospital mortality by case was higher in lenient (7.5%) versus strict (6.5%) states, p = 0.013. Lenient states had a proportionally higher rate of accidental (31%) and self-inflicted injury (4%) versus strict states (17% and 1.6%, respectively), p < 0.001. Assault-related injuries were proportionally lower in lenient (54%) versus strict (75%) states, p < 0.001. Military-grade weapons were more common in lenient (0.4%) versus strict (0.1%) states, p = 0.001.

CONCLUSIONS

These findings highlight the importance of legislative measures and their role in injury prevention, as firearm injuries are entirely avoidable mechanisms of injury. Lenient gun control contributes not only to worse outcomes per case, but also to a more significant and detrimental impact on public health.
