Does socioeconomic status predict outcomes after cholecystectomy?

Clinical and socioeconomic factors predicting return-to-work times after cholecystectomy

BACKGROUND

Cholecystectomy, a type of surgery commonly performed globally, has possible mutual effects on the socioeconomic conditions of different countries due to various postoperative recovery times.

AIMS

This study evaluated the medical and socioeconomic factors affecting delayed return-to-work (RTW) time after elective cholecystectomy.

METHODS

This retrospective study analysed patients who underwent elective cholecystectomy for benign gallbladder diseases from January 2022 to April 2023. The patients' medical and socioeconomic data were collected to investigate the clinical and socioeconomic factors correlated with RTW time of >30 days after surgery.

RESULTS

This study included 180 consecutive patients. Significant correlations were found between delayed RTW time (>30 days) and age (odds ratio [OR]: 1.059, 95% confidence interval [CI] 1.008-1.113, P = 0.024), lack of medical insurance (OR: 2.935, 95% CI 1.189-7.249, P = 0.02) and high-intensity labour jobs (OR: 3.649, 95% CI 1.495-8.909, P = 0.004). Patients without medical insurance (26.6 versus 18.9 days) and those with high-intensity labour jobs (23.9 versus 18.8 days) had a higher mean RTW time than those with insurance and a less-intense labour job (P < 0.001).

CONCLUSIONS

After cholecystectomy, older age, lack of medical insurance and high-intensity labour job were correlated with a delayed RTW time. Informing patients about their expected RTW time after surgery can help reduce costs.

Social vulnerability and surgery outcomes: a cross-sectional analysis

BACKGROUND

Post-operative complications present a challenge to the healthcare system due to the high unpredictability of their incidence. Socioeconomic conditions have been established as social determinants of health. However, their contribution relating to postoperative complications is still unclear as it can be heterogeneous based on community, type of surgical services, and sex and gender. Uncovering these relations can enable improved public health policy to reduce such complications.

METHODS

In this study, we conducted a large population cross-sectional analysis of social vulnerability and the odds of various post-surgical complications. We collected electronic health records data from over 50,000 surgeries that happened between 2012 and 2018 at a quaternary health center in St. Louis, Missouri, United States and the corresponding zip code of the patients. We built statistical logistic regression models of postsurgical complications with the social vulnerability index of the tract consisting of the zip codes of the patient as the independent variable along with sex and race interaction.

RESULTS

Our sample from the St. Louis area exhibited high variance in social vulnerability with notable rapid increase in vulnerability from the south west to the north of the Mississippi river indicating high levels of inequality. Our sample had more females than males, and females had slightly higher social vulnerability index. Postoperative complication incidence ranged from 0.75% to 41% with lower incidence rate among females. We found that social vulnerability was associated with abnormal heart rhythm with socioeconomic status and housing status being the main association factors. We also found associations of the interaction of social vulnerability and female sex with an increase in odds of heart attack and surgical wound infection. Those associations disappeared when controlling for general health and comorbidities.

CONCLUSIONS

Our results indicate that social vulnerability measures such as socioeconomic status and housing conditions could affect postsurgical outcomes through preoperative health. This suggests that the domains of preventive medicine and public health should place social vulnerability as a priority to achieve better health outcomes of surgical interventions.

Barriers to elective cholecystectomy following emergency department discharge for symptomatic cholelithiasis

BACKGROUND

Patients with symptomatic cholelithiasis are often discharged from the Emergency Department (ED) and asked to follow-up for elective cholecystectomy. We aimed to identify the social determinants of health (SDOH) that serve as barriers to elective cholecystectomy and to assess the associated impact on patient outcomes.

METHODS

We conducted a multi-institutional, retrospective cohort study of patients discharged from the ED with symptomatic cholelithiasis. Univariable logistic regression was used to assess for variables associated with re-presenting to the ED rather than for elective cholecystectomy. P values ​< ​0.05 identified significance.

RESULTS

Univariate analysis identified lack of a primary care physician, Black race, self-pay, language other than English as the primary language, and unemployed status to be independently associated with re-presentation to the ED for biliary disease.

CONCLUSIONS

Socially disadvantaged populations would benefit from surgery at the time of presentation to the ED versus being sent home for elective follow-up.

Impact of pandemic and socioeconomic influences on decision-making for emergency ostomy procedures: Key factors affecting hospital visit decisions

Emergency surgeries are linked with increased morbidity and reduced life expectancy, often associated with low socioeconomic status, limited access to healthcare, and delayed hospital admissions. While the influence of socioeconomic status on elective surgery outcomes is well-established, its impact on emergency surgeries, including ostomy creation and closure, is less clear. This study aimed to explore how the pandemic and socioeconomic status affect emergency ostomy procedures, seeking to determine which has a greater effect. It emphasizes the importance of considering socioeconomic factors in patient care pathways for ostomy procedures. A total of 542 patients who underwent emergency ostomy formation between 2016 and 2022 were retrospectively analyzed and divided into pre-pandemic and pandemic periods. The pre-pandemic and pandemic periods were compared between themselves and against each other. Demographic data (age and sex), comorbidities, socioeconomic status, etiology of the primary disease, type of surgery, stoma type, length of hospital stay, ostomy closure time, and postoperative complications were retrospectively analyzed for all patients. In total, 290 (53%) patients underwent surgery during the pandemic period, whereas 252 (47%) underwent surgery during the pre-pandemic period. Emergency surgery was performed for malignancy in 366 (67%) patients. The number of days patients underwent ostomy closure was significantly higher in the low-income group (P = .038, 95% CI: 293,2, 386-945). The risk of failure of stoma closure was 3-fold (95% CI: 1.8-5.2) in patients with metastasis. The risk of mortality was 12.4-fold (95% CI: 6.5-23.7) when there was failure of stoma closure. When compared to pandemic period, the mortality risk was 6.3-fold (95% CI: 3.9-10.2) in pre-pandemic period. Pandemic patients had a shorter hospital stay than before the pandemic (P = .044). A high socioeconomic status was significantly associated with early hospital admission for ostomy closure, and lower probability of mortality. More metastases and perforations were observed during the pandemic period and mortality was increased during pandemic and in patients without ostomy closure. The socioeconomic status lost its effect in cases of emergency ostomy creation and had no impact on length of hospital stay in either the pre-pandemic or pandemic period.

Social Determinants of Health Associated With the Need for Urgent Versus Elective Cholecystectomy at an Urban, Safety-Net Hospital

Background: Benign gallstone disease is the most frequent indication for cholecystectomy in the United States. Many patients present with complicated disease requiring urgent interventions, which increases morbidity and mortality. We investigated the association between individual and population-level social determinants of health (SDoH) with urgent versus elective cholecystectomy. Patients and Methods: All patients undergoing cholecystectomy (2014-2021) for benign gallstone disease were included. Demographic and clinical data were linked to population-level SDoH characteristics using census tracts. Data were analyzed using descriptive and inferential statistics. Results: A total of 3,197 patients met inclusion criteria; 1,913 (59.84%) underwent urgent cholecystectomy, 1,204 (37.66%) underwent emergent cholecystectomy, and 80 (2.5%) underwent interval cholecystectomy. On multinomial logistic regression, patients who were older (relative risk [RR], 1.010; p < 0.001), black (RR, 1.634; p = 0.008), and living in census tracts with a higher percent of poverty (RR, 0.017; p = 0.021) had a higher relative risk of presenting for urgent cholecystectomy. Patients who were female (RR, 0.462; p < 0.001), had a primary care provider (PCP; RR, 0.821; p = 0.018), and lived in census tracts with low supermarket access (RR, 0.764; p = 0.038) had a lower relative risk of presenting for urgent cholecystectomy. Only age (RR, 1.066; p < 0.001), female gender (RR, 0.227; p < 0.001), and having a PCP (RR, 1.984; p = 0.034) were associated with presentation for interval cholecystectomy. Conclusions: Patients who were older, black, and living in census tracts with high poverty levels had a higher relative risk of presenting for urgent cholecystectomy at our institution, whereas females and patients with PCPs were more likely to undergo elective cholecystectomy. Improved access to primary care and surgical clinics for all patients at safety-net hospitals may result in improved outcomes in the management of benign gallstone disease by increasing diagnosis and treatment in the elective setting.

Not all cholecystitis is created equal: Disparities contributing to ED presentation and failure of the outpatient algorithm

BACKGROUND

The majority of final surgical pathology (FSP) from both emergency department (ED) and outpatient clinic (OC) patients is chronic cholecystitis. We aimed to differentiate these presentations and identify disparities associated with ED utilization and OC failure.

METHODS

Retrospective chart review of single institution ED and OC cholecystectomies for cholelithiasis. Clinical presentation, FSP, demographics, and zip code poverty (ZCP) levels were evaluated. Data analysis by summary statistics, bivariate comparisons, and logistic regression.

RESULTS

Of 299 OC and 308 ED patients, OC was more likely to be Caucasian (78% vs 46%, p < 0.0001) and insured (89% vs. 32%, p < 0.0001). 71.8% of OC with ZCP <10% had insurance versus only 32.5% in ZCP >20%. Uninsured ED OR was 13.1 (95% CI 8.7-22.9).

CONCLUSION

Uninsured ED patients are vulnerable to fail the outpatient algorithm, especially when misdiagnosed by US. Clinical diagnosis of cholecystitis in this population should warrant offering of urgent cholecystectomy.

Social Vulnerability and Surgery Outcomes: A Cross-sectional Analysis

Background

Post-operative complications present a challenge to the healthcare system due to the high unpredictability of their incidence. However, the socioeconomic factors that relate to postoperative complications are still unclear as they can be heterogeneous based on communities, types of surgical services, and sex and gender.

Methods

In this study, we conducted a large population cross-sectional analysis of social vulnerability and the odds of various post-surgical complications. We built statistical logistic regression models of postsurgical complications with social vulnerability index as the independent variable along with sex interaction.

Results

We found that social vulnerability was associated with abnormal heart rhythm with socioeconomic status and housing status being the main association factors. We also found associations of the interaction of social vulnerability and female sex with an increase in odds of heart attack and surgical wound infection.

Conclusions

Our results indicate that social vulnerability measures such as socioeconomic status and housing conditions could be related to health outcomes. This suggests that the domain of preventive medicine should place social vulnerability as a priority to achieve its goals.

There Is No Such Thing as Too Soon: Long-Term Outcomes of Early Cholecystectomy for Frail Geriatric Patients with Acute Biliary Pancreatitis

BACKGROUND

Early cholecystectomy (CCY) for acute biliary pancreatitis (ABP) is recommended but there is a paucity of data assessing this approach in frail geriatric patients. This study compares outcomes of frail geriatric ABP patients undergoing index admission CCY vs nonoperative management (NOM) with endoscopic retrograde cholangiopancreatography (ERCP).

STUDY DESIGN

Retrospective analysis of the Nationwide Readmissions Database (2017). All frail geriatric (65 years or older) patients with ABP were included. Patients were grouped by treatment at index admission: CCY vs NOM with endoscopic retrograde cholangiopancreatography. Propensity score matching was performed in a 1:2 ratio. Primary outcomes were 6-month readmissions, mortality, and length of stay. Secondary outcomes were 6-month failure of NOM defined as readmission for recurrent ABP, unplanned pancreas-related procedures, or unplanned CCY. Subanalysis was performed to compare outcomes of unplanned CCY vs early CCY.

RESULTS

A total of 29,130 frail geriatric patients with ABP were identified and 7,941 were matched (CCY 5,294; NOM 2,647). Patients in the CCY group had lower 6-month rates of readmission for pancreas-related complications, unplanned readmissions for pancreas-related procedures, overall readmissions, and mortality, as well as fewer hospitalized days (p < 0.05). NOM failed in 12% of patients and 7% of NOM patients were readmitted within 6 months to undergo CCY, of which 56% were unplanned. Patients who underwent unplanned CCY had higher complication rates and hospital costs, longer hospital lengths of stay, and increased mortality compared with early CCY (p < 0.05).

CONCLUSIONS

For frail geriatric patients with ABP, early CCY was associated with lower 6-month rates of complications, readmissions, mortality, and fewer hospitalized days. NOM was unsuccessful in nearly 1 of 7 within 6 months; of these, one-third required unplanned CCY. Early CCY should be prioritized for frail geriatric ABP patients when feasible.

Novel Application of Hydrodissection in Laparoscopic Cholecystectomy for Gangrenous Gallbladders

INTRODUCTION

Laparoscopic cholecystectomy (LC) for gangrenous gallbladders (GGBs) can be challenging and represent a significant number of LC cases, necessitating more efficacious surgical techniques. Currently, the standard treatment for GGBs is blunt dissection which can have high iatrogenic complication rates. To our knowledge, this is the first large retrospective study conducted on the novel application of hydrodissection (HD) in LCs for GGBs.

METHODS

In this retrospective study of 386 LCs, data were collected for patient demographics, medical comorbidities, operating time (OT), anesthesia time (AT), length of stay (LOS), estimated blood loss, conversion to open procedures, 30-day readmissions, and mortality. Patients were categorized into four groups: (1) Vyas employing HD for GGBs (VHG), (2) non-Vyas group of five surgeons not employing HD for GGBs (NVG), (3) Vyas treating non-GGBs, and (4) non-Vyas group of five surgeons treating non-GGBs. Control groups were age-matched and sex-matched. Statistical analysis used descriptive statistics, Mann-Whitney U testing, and chi-squared testing (α = 0.05).

RESULTS

This study demonstrated significantly decreased (P < 0.05) OT (P = 0.001), AT (P < 0.001), LOS (P = 0.015), and conversion to open procedures (P = 0.047) between the VHG and NVG groups, with HD reducing OT by 35.5% compared to blunt dissection. This study did not demonstrate significantly decreased (P > 0.05) estimated blood loss (P = 0.185) and 30-day readmissions (P = 0.531) between the VHG and NVG groups, but they were trending toward significant. There were no mortalities in this study.

CONCLUSIONS

HD is associated with improved surgical outcomes of LCs for GGBs demonstrated by reduced OT, AT, LOS, and conversion to open procedures. Further multi-institutional studies are needed to validate HD implementation and further dissemination.

Trends and Burden of Firearm-Related Injuries Among Children and Adolescents: A National Perspective

INTRODUCTION

Firearm-related injuries in America have been under increasing scrutiny over the last several years. Few studies have examined the burden of these injuries in the pediatric population. The objective of this study was to describe the incidence of firearm-related injuries in hospitalized pediatric patients in the United States and identify the risk factors associated with readmission in this young population.

METHODS

The Nationwide Readmission Database was examined from 2010 to 2017. Pediatric patients (aged ≤18 y) who survived their index hospitalization for any firearm injury were analyzed to determine incidence rate, case fatality rate, risk factors for 30-d readmission, and financial health care burden.

RESULTS

There were 35,753 pediatric firearm injuries (86.8% male) with an overall incidence rate of 10.49 (95% confidence interval [CI]: 9.26-11.71) per 100,000 pediatric hospitalizations. Adolescents aged >12 y had the highest incidence rate (60.51, 95% CI: 55.19-65.84). In-hospital mortality occurred in 1948 cases (5.5%), with higher case fatality rates in males. There were 1616 (5.7%) unplanned 30-d readmissions. Multivariate analysis showed abdominal firearm injuries (hazard ratio: 1.13, 95% CI: 1.03-1.24; P = 0.006) and longer length of stay (hazard ratio: 1.27, 95% CI: 1.04-1.55; P = 0.016) were associated with a greater risk of 30-d readmission. The median health care cost for firearm-related injuries was $36,535 (interquartile range: $19,802-$66,443), 22% of which was due to readmissions. Cost associated with 30-d readmissions was $7978 (interquartile range: $4305-$15,202).

CONCLUSIONS

Firearm-related injury is a major contributor to pediatric morbidity, mortality, and health care costs. Males are disproportionately affected by firearm injury, but females are more likely to require unplanned 30-d readmissions. Interventions should target female sex, injuries of suicidal intent, psychiatric comorbidities, prolonged index hospitalization, and abdominal injuries.

Re-Admission in Patients with Necrotizing Soft Tissue Infections: Continuity of Care Matters

Background: Necrotizing soft tissue infections (NSTIs) are rapidly progressive infections with high mortality and complication rates. The incidence of NSTIs has been increasing steadily whereas mortality has decreased; survivors have a high risk of re-hospitalization. We hypothesized that re-admission to the index hospital where the first admission occurred would be associated with better clinical outcomes compared with re-admission to a non-index hospital. Patients and Methods: We identified patients from the 2017 Nationwide Readmissions Database with an index admission for NSTIs and examined all-cause re-admissions within 90 days of discharge. We noted whether re-admission occurred at the index or a non-index hospital. Survey-weighted logistic regression identified factors associated with death at the first re-admission and re-admission to index hospital. We also compared patient outcomes between patients admitted to index versus non-index hospitals. Results: We identified 27,051 NSTI survivors, of whom 6,954 (25.7%) had an unplanned re-admission within 90 days. A large proportion of re-admission occurred at non-index hospitals (28.3%; n = 1,966). Factors associated with non-index re-admission included prolonged index length of stay, discharge to short-term hospital, and leaving against medical advice. Patients re-admitted to index hospitals had a lower mortality rate (4.7% vs. 6.7%; p = 0.003), lower admission costs (in $1000; 45 [23-88] vs. 50 [24-104]; p = 0.004) and higher discharge rate to home (55.7% vs. 48.6%; p < 0.001). Conclusions: More than one-quarter of re-admissions among NSTI survivors were to non-index hospitals. Continuity of care is important because re-admission to the index hospital was associated with better patient outcomes.

Comparing outcomes of cholecystectomies in white vs. minority patients

BACKGROUND

This study aimed to investigate the disparity between white and minority patients undergoing cholecystectomies, including presentation, outcomes, and financial burden.

METHODS

This was an IRB approved retrospective review of all cholecystectomies at an academic medical center from 2013 to 2018. Data collected include demographics, insurance type, charge of admission, and clinical outcomes.

RESULTS

1539 patients underwent cholecystectomies. Of those, 36.9% were white and 63.1% were minority. Minority patients presented at a younger age than white patients (45.5 vs 53.9, p < 0.01) and required emergent admission (76.2% vs 68.4%, p < 0.01). No significant difference was found for clinical outcomes between white and minority. Minority patients were more commonly uninsured (32.1%). Among the uninsured, self-pay had a higher charge than emergency MediCal (by 5.46 per 1000 dollars).

CONCLUSION

Minority patients are more commonly disadvantaged at presentation and charged more due to insurance status despite similar outcomes after cholecystectomies.

Systematic Review: Impact of Social Determinants of Health on the Management and Prognosis of Gallstone Disease

Background:

Due to its prevalence, gallstone disease is a major public health issue. It affects diverse patient populations across various socioeconomic levels. Socioeconomic and geographic deprivation may impact both morbidity and mortality associated with digestive diseases, such as biliary tract disease.

Aim:

The aim of this systematic review was to review the available data on the impact of socioeconomic determinants and geographic factors on gallstone disease and its complications.

Methods:

This systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The MEDLINE and Web of Science databases were searched by two investigators to retrieve studies about the impact of income, insurance status, hospital status, education level, living areas, and deprivation indices on gallstone disease. Thirty-seven studies were selected for this review.

Results:

Socially disadvantaged populations appear to be more frequently affected by complicated or severe forms of gallstone disease. The prognosis of biliary tract disease is poor in these populations regardless of patient status, and increased morbidity and mortality were observed for acute cholangitis or subsequent cholecystectomy. Limited or delayed access and low-quality therapeutic interventions could be among the potential causes for this poor prognosis.

Conclusions:

This systematic review suggests that socioeconomic determinants impact the management of gallstone disease. Enhanced knowledge of these parameters could contribute to improved public health policies to manage these diseases.

Socioeconomic disadvantage is associated with greater mortality after high-risk emergency general surgery

BACKGROUND

Socioeconomic disadvantage is associated with worse outcomes after elective surgery, but the effect on emergency general surgery (EGS) remains unclear. We examined the association of socioeconomic disadvantage and outcomes after EGS procedures and investigated whether admission to hospitals with comprehensive clinical and social resources mitigated this effect.

METHODS

Adults undergoing 1 of the 10 most burdensome high- and low-risk EGS procedures were identified in six 2014 State Inpatient Databases. Socioeconomic disadvantage was assessed using Area Deprivation Index (ADI) of patient residence. Multivariable logistic regression models adjusting for patient and hospital factors were used to evaluate the association between ADI quartile (high >75 percentile vs. low <25 percentile), and 30-day readmission, in-hospital mortality, and discharge disposition. Effect modification between ADI and (a) level 1 trauma center and (b) safety-net hospital status was tested.

RESULTS

A total of 103,749 patients were analyzed: 72,711 low-risk (70.1%) and 31,038 high-risk procedures (29.9%). Patients from neighborhoods with high socioeconomic disadvantage had a higher proportion with ≥3 comorbidities (41.9% vs. 32.0%), minority race/ethnicity (66.3% vs. 42.4%), and Medicaid (28.8% vs. 14.7%) and were less likely to be treated at level 1 trauma centers (18.3% vs. 27.7%; p < 0.001 for all). Adjusting for competing factors, high socioeconomic disadvantage was associated with increased in-hospital mortality after high-risk procedures (odd ratio, 1.30; 95% confidence interval, 1.01-1.66; p = 0.04) and higher odds of non-home discharge (odd ratio, 1.15; 95% confidence interval, 1.02-1.30; p = 0.03) for low-risk procedures. Socioeconomic disadvantage was not associated with 30-day readmission for either procedure group. Level 1 trauma status and safety-net hospital did not meaningfully mitigate effect of ADI for any outcome.

CONCLUSION

Socioeconomic disadvantage is associated with increased mortality after high-risk procedures and higher odds of non-home discharge after low-risk procedures. This effect was not mitigated by either level 1 trauma or safety-net hospitals. Interventions that specifically address the needs of socially vulnerable communities will be required to significantly improve EGS outcomes for this population.

Association of Race and Family Socioeconomic Status With Pediatric Postoperative Mortality

IMPORTANCE

Racial disparities in postoperative outcomes have remained difficult to eliminate. It is commonly understood that socioeconomic status (SES) is an important factor associated with excess risk of postoperative morbidity and death. To date, comparable data exploring the association of family SES with pediatric postoperative mortality are unavailable, and it is unknown whether the advantage provided by higher income status is equitable across racial groups.

OBJECTIVE

To assess whether increasing family SES is associated with lower pediatric postoperative mortality and, if so, whether this association is equitable among Black and White children.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cohort study used data from 51 freestanding pediatric tertiary care hospitals across the US that reported to the Children's Hospital Association Pediatric Health Information System. The study included 1 378 111 Black and White children younger than 18 years who underwent inpatient surgical procedures between January 1, 2004, and December 31, 2020.

EXPOSURES

The exposures of interest were race (Black and White) and parental income quartile (used as a proxy for SES and measured by median income quartile of the zip code of residence). Race was self-reported by parents or guardians at admission or assessed by the registration team consistent with each hospital's policy and state legislation.

MAIN OUTCOMES AND MEASURES

The primary outcome was risk-adjusted in-hospital mortality rates by race and parental income quartile controlled for baseline covariates. To evaluate whether belonging to the highest income quartile modified the association between race and postoperative mortality, multiplicative and additive interactions were examined.

RESULTS

Among 1 378 111 children (773 364 [56.1%] male; mean [SD] age, 7 [6] years) who received inpatient surgical procedures during the study period, 248 464 children (18.0%) were Black, and 1 129 647 children (82.0%) were White; 211 127 children (15.3%) were Hispanic, and 825 477 (59.9%) were non-Hispanic. Only 49 541 Black children (20.3%) belonged to the highest income quartile compared with 482 758 White children (43.0%). The overall mortality rate was 1.2%, and mortality rates decreased as income quartile increased (1.4% in quartile 1 [lowest income], 1.3% in quartile 2, 1.0% in quartile 3, and 0.9% in quartile 4 [highest income]; P < .001). Among those belonging to the 3 lowest income quartiles, Black children had 33% higher odds of postoperative death compared with White children (adjusted odds ratio, 1.33; 95% CI, 1.27-1.39; P < .001). This racial disparity gap persisted among children belonging to the highest income quartile (adjusted odds ratio, 1.39; 95% CI, 1.25-1.54; P < .001). Postoperative mortality rates among Black children in the highest income quartile (1.30%; 95% CI, 1.19%-1.42%) were comparable to those of White children in the lowest income quartile (1.20%; 95% CI, 1.16%-1.25%). The interaction between Black race and income was not statistically significant on either the multiplicative scale (β for interaction = 1.04; 95% CI, 0.93-1.17; P = .45) or the additive scale (relative excess risk due to interaction = 0.01; 95% CI, -0.11 to 0.11; P > .99), suggesting no reduction in the disparity gap across increasing income levels.

CONCLUSIONS AND RELEVANCE

In this cohort study, increasing SES was associated with lower pediatric postoperative mortality. However, postoperative mortality rates were significantly higher among Black children in the highest SES category compared with White children in the same category, and mortality rates among Black children in the highest SES category were comparable to those of White children in the lowest SES category. These findings suggest that increasing family SES did not provide equitable advantage to Black compared with White children, and interventions that target socioeconomic inequities alone may not fully address persistent racial disparities in pediatric postoperative mortality.

The burden of readmission after discharge from necrotizing soft tissue infection

BACKGROUND

The need for extensive surgical debridement with necrotizing soft tissue infections (NSTIs) may put patients at high risk for unplanned readmission. However, there is a paucity of data on the burden of readmission in patients afflicted with NSTI. We hypothesized that unplanned readmission would significantly contribute to the burden of disease after discharge from initial hospitalization.

METHODS

The Nationwide Readmission Database was used to identify adults undergoing debridement for NSTI hospitalizations from 2010 to 2017. Risk factors for 90-day readmission were assessed by Cox proportional hazards regression.

RESULTS

There were a total of 82,738 NSTI admissions during the study period, of which 25,076 (30.3%) underwent 90-day readmissions. Median time to readmission was 25 days (interquartile range, 9-49 days). Fragmentation of care, longer length of index stay (>2 weeks), and Medicaid status were independent risk factors for readmission. Median cost of a readmission was US $10,543. Readmission added 174,640 hospital days to episodes of care over the study period, resulting in an estimated financial burden of US $1.4 billion.

CONCLUSION

Unplanned readmission caused by NSTIs is common and costly. Interventions that target patients at risk for readmission may help decrease the burden of disease.

The effect of household income on outcomes following supratentorial meningioma resection

OBJECTIVE

This study assesses the impact of Median Household Income (MHI) on short- and long-term morbidity and mortality following supratentorial meningioma resection.

PATIENTS AND METHODS

351 consecutive patients undergoing supratentorial meningioma tumor resection, at a single health system over a six-year period (June 09, 2013 to April 26, 2019) were analyzed retrospectively. Outcomes assessed included readmission, emergency department (ED) evaluation, and mortality within 90 days of surgery. Univariate regression analysis was conducted amongst the entire population. The population was then divided into quartiles based on median household income and univariate analysis was conducted between the lowest (Q1) and highest (Q4) quartiles. Significance was set at a P-value < 0.05. Stepwise regression was performed to identify confounding variables in the logistic model.

RESULTS

In the whole population, lower Median Household Income correlated to a significant increase in ED evaluation within 90-days of supratentorial meningioma resection. No significant difference was noted between median household income and 90-day readmission, 90-day unplanned re-operation, return to surgery after index admission within 90-days, return to surgery during the duration of the follow-up period, mortality within 90-days, and mortality during the duration of the follow-up period. In addition, when comparing Q1 (MHI ≤ $51,780) and Q4 (MHI ≥ $87,958), similar results were noted with increased ED evaluation for patients with lower MHI, but no significant difference in other factors of morbidity or mortality.

CONCLUSION

Following supratentorial meningioma resection, a lower median household income was significantly associated with increased emergency department visits within 90 post-operative days.

Treatment of Acute Cholecystitis: Do Medicaid and Non-Medicaid Enrolled Patients Receive the Same Care?

BACKGROUND

Nationally, Medicaid enrollees with emergency surgical conditions experience worse outcomes overall when compared with privately insured patients. The goal of this study is to investigate disparities in the treatment of cholecystitis based on insurance type and to identify contributing factors.

METHODS

Adults with cholecystitis at a safety-net hospital in Central Massachusetts from 2017-2018 were included. Sociodemographic and clinical characteristics were compared based on Medicaid enrollment status (Medicare excluded). Univariate and multivariate analyses were used to compare the frequency of surgery, time to surgery (TTS), length of stay (LOS), and readmission rates between groups.

RESULTS

The sample (n = 203) included 69 Medicaid enrollees (34%), with a mean age of 44.4 years. Medicaid enrollees were younger (p = 0.0006), had lower levels of formal education (high school diploma attainment, p < 0.0001), were more likely to be unmarried (p < 0.0001), Non-White (p = 0.0012), and require an interpreter (p < 0.0001). Patients in both groups experienced similar rates of laparoscopic cholecystectomy, TTS, and LOS; however, Medicaid enrollees experienced more readmissions within 30 days of discharge (30.4% vs 17.9%, p < 0.001).

CONCLUSION

Despite anticipated population differences, the treatment of acute cholecystitis was similar between Medicaid and Non-Medicaid enrollees, with the exception of readmission. Further research is needed to identify patient, provider, and/or population factors driving this disparity.

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.

Effect of socioeconomic inequalities on cholecystectomy outcomes: a 10-year population-based analysis

BACKGROUND

Although numerous epidemiological studies on cholecystectomy have been conducted worldwide, only a few have considered the effect of socioeconomic inequalities on cholecystectomy outcomes. Specifically, few studies have focused on the low-income population (LIP).

METHODS

A nationwide prospective study based on the Taiwan National Health Insurance dataset was conducted during 2003-2012. The International Classification of ICD-9-CM procedure codes 51.2 and 51.21-51.24 were identified as the inclusion criteria for cholecystectomy. Temporal trends were analyzed using a joinpoint regression, and the hierarchical linear modeling (HLM) method was used as an analytical strategy to evaluate the group-level and individual-level factors. Interactions between age, gender and SES were also tested in HLM model.

RESULTS

Analyses were conducted on 225,558 patients. The incidence rates were 167.81 (95% CI: 159.78-175.83) per 100,000 individuals per year for the LIP and 123.24 (95% CI: 116.37-130.12) per 100,000 individuals per year for the general population (GP). After cholecystectomy, LIP patients showed higher rates of 30-day mortality, in-hospital complications, and readmission for complications, but a lower rate of routine discharge than GP patients. The hospital costs and length of stay for LIP patients were higher than those for GP patients. The multilevel analysis using HLM revealed that adverse socioeconomic status significantly negatively affects the outcomes of patients undergoing cholecystectomy. Additionally, male sex, advanced age, and high Charlson Comorbidity Index (CCI) scores were associated with higher rates of in-hospital complications and 30-day mortality. We also observed that the 30-day mortality rates for patients who underwent cholecystectomy in regional hospitals and district hospitals were significantly higher than those of patients receiving care in a medical center.

CONCLUSION

Patients with a disadvantaged finance status appeared to be more vulnerable to cholecystectomy surgery. This result suggested that further interventions in the health care system are necessary to reduce this disparity.

Outcomes in the Utilization of Single Percutaneous Cholecystostomy in a Low-Income Population

Numerous studies have investigated the applicable populations for percutaneous cholecystostomy (PC) procedures, but the outcomes of PC in low-income populations (LIPs) have been insufficiently studied. Data for 11,184 patients who underwent PC were collected from the National Health Insurance Research Database of Taiwan during 2003 and 2012. The overall crude rate of single PC for the LIP was 64% higher than that for the general population (GP). After propensity score matching for the LIP and GP at a ratio of 1:5, the outcome analysis of patients who underwent PC showed that in-hospital mortality was significantly higher in the LIP group than in the GP group, but one-year recurrence was lower. The rates of 30-day mortality and in-hospital complications were higher for the LIP patients than for the GP patients, and the rate of routine discharge was lower, but the differences were not significant. In conclusion, LIP patients undergoing PC exhibit poor prognoses relative to GP patients, indicating that a low socioeconomic status has an adverse impact on the outcome of PC. We suggest that surgeons fully consider the patient’s financial situation during the operation and further consider the possible poor post-surgical outcomes for LIP patients.

Practice Patterns for Cholecystectomy After Endoscopic Retrograde Cholangiopancreatography for Patients With Choledocholithiasis

BACKGROUND & AIMS

Cholecystectomy (CCY) after an episode of choledocholithiasis requiring endoscopic retrograde cholangiopancreatography (ERCP) with stone extraction reduces recurrent biliary events compared to expectant management. We studied practice patterns for performance of CCY after ERCP for choledocholithiasis using data from 3 large states and evaluated the effects of delaying CCY.

METHODS

We conducted a retrospective cohort study using the ambulatory surgery, inpatient, and emergency department databases from the states of California (years 2009-2011), New York (2011-2013), and Florida (2012-2014). We collected data from 4516 patients hospitalized with choledocholithiasis who underwent ERCP. We compared outcomes of patients who underwent CCY at index admission (early CCY), elective CCY within 60 days of discharge (delayed CCY), or did not undergo CCY (no CCY), calculating rate of recurrent biliary events (defined as an emergency department visit or unplanned hospitalization due to symptomatic cholelithiasis, cholecystitis, choledocholithiasis, cholangitis, or biliary pancreatitis), mortality, and cost by CCY cohort. We also evaluated risk factors for not undergoing CCY. The primary outcome measure was the rate of recurrent biliary events in the 365 days after discharge from index admission.

RESULTS

Of the patients who underwent ERCP for choledocholithiasis, 41.2% underwent early CCY, 10.9% underwent delayed CCY, and 48.0% underwent no CCY. Early CCY reduced relative risk of recurrent biliary events within 60 days by 92%, compared with delayed or no CCY (P < .001). After 60 days following discharge from index admission, patients with early CCY had an 87% lower risk of recurrent biliary events than patients with no CCY (P < .001) and patients with delayed CCY had an 88% lower risk of recurrent biliary events than patients with no CCY (P < .001). A strategy of delayed CCY performed on an outpatient basis was least costly. Performance of early CCY was inversely associated with low facility volume. Hispanic race, Asian race, Medicaid insurance, and no insurance associated inversely with performance of delayed CCY.

CONCLUSIONS

In a retrospective analysis of >4500 patients hospitalized with choledocholithiasis, we found that CCY was not performed after ERCP for almost half of the cases. Although early and delayed CCY equally reduce the risk of subsequent recurrent biliary events, patients are at 10-fold higher risk of recurrent biliary event while waiting for a delayed CCY compared with patients who underwent early CCY. Delayed CCY is a cost-effective strategy that must be balanced against the risk of loss to follow-up, particularly among patients who are ethnic minorities or have little or no health insurance.
