Utilization of minimally invasive colectomy at safety-net hospitals in the United States.

BACKGROUND: Prior literature has reported inferior surgical outcomes and reduced access to minimally invasive procedures at safety-net hospitals. However, this relationship has not yet been elucidated for elective colectomy. We sought to characterize the association between safety-net hospitals and likelihood of minimally invasive resection, perioperative outcomes, and costs. METHODS: All adult (≥18 years) hospitalization records entailing elective colectomy were identified in the 2016-2020 National Inpatient Sample. Centers in the top quartile of safety-net burden were considered safety-net hospitals (others: non-safety-net hospitals). Multivariable regression models were developed to assess the impact of safety-net hospitals status on key outcomes. RESULTS: Of ∼532,640 patients, 95,570 (17.9%) were treated at safety-net hospitals. The safety-net hospitals cohort was younger and more often of Black race or Hispanic ethnicity. After adjustment, care at safety-net hospitals remained independently associated with reduced odds of minimally invasive surgery (adjusted odds ratio 0.92; 95% confidence interval 0.87-0.97). The interaction between safety-net hospital status and race was significant, such that Black race remained linked with lower odds of minimally invasive surgery at safety-net hospitals (reference: White race). Additionally, safety-net hospitals was associated with greater likelihood of in-hospital mortality (adjusted odds ratio 1.34, confidence interval 1.04-1.74) and any perioperative complication (adjusted odds ratio 1.15, confidence interval 1.08-1.22), as well as increased length of stay (ß+0.26 days, confidence interval 0.17-0.35) and costs (ß+$2,510, confidence interval 2,020-3,000). CONCLUSION: Care at safety-net hospitals was linked with lower odds of minimally invasive colectomy, as well as greater complications and costs. Black patients treated at safety-net hospitals demonstrated reduced likelihood of minimally invasive surgery, relative to White patients. Further investigation is needed to elucidate the root causes of these disparities in care.

Association of uninsured status and rurality with risk of financial toxicity after pediatric trauma.

BACKGROUND: Pediatric traumatic injury is associated with long-term morbidity as well as substantial economic burden. Prior work has labeled the catastrophic out-of-pocket medical expenses borne by patients as financial toxicity. We hypothesized uninsured rural patients to be vulnerable to exorbitant costs and thus at greatest risk of financial toxicity. METHODS: Pediatric patients (<18 years) experiencing traumatic injury were identified in the 2016-2019 National Inpatient Sample. Patients were considered to be at risk of financial toxicity if their hospitalization cost exceeded 40% of post-subsistence income. Individual family income was computed using a gamma distribution probability density function with parameters derived from publicly available US Census Bureau data, in accordance with prior work. A multivariable logistic regression was developed to assess factors associated with risk of financial toxicity. RESULTS: Of an estimated 225,265 children identified for study, 34,395 (15.3%) were Rural. Rural patients were more likely to experience risk of financial toxicity (29.1 vs 22.2%, P < .001) compared to Urban patients. After adjustment, rurality (reference: urban status; adjusted odds ratio 1.45, 95% confidence interval 1.36-1.55) and uninsured status (reference: private; adjusted odds ratio 1.85, 95% confidence interval 1.67-2.05) remained linked to increased odds of risk of financial toxicity. Specifically among those with private insurance, Rural patients experienced markedly higher predicted risk of financial toxicity, relative to Urban. CONCLUSION: Our findings suggest a complex interplay between rural status and insurance type in the prediction of risk of financial toxicity after pediatric trauma. To target policy interventions, future studies should characterize the patients and communities at greatest risk of financial devastation among rural pediatric trauma patients.

Clinical Outcomes and Resource Utilization in Patients With Peripheral Arterial Disease Hospitalized for Acute Coronary Syndrome.

Previous studies have shown an association between acute limb ischemia and higher mortality in patients with acute myocardial infarction. Although peripheral artery disease (PAD) is a well-known risk factor for development of macrovascular pathology, the effect of its severity is not well investigated in patients hospitalized for acute coronary syndrome (ACS). Using a national cohort of patients with various degrees of PAD, we investigated in-hospital outcomes in patients who were admitted for ACS. Using the 2016 to 2020 Nationwide Readmissions Database, we queried all patients who were hospitalized for ACS (unstable angina, non-ST-elevation myocardial infarction, and ST-elevation myocardial infarction). Patients were further divided into 3 groups, either no PAD (non-PAD), PAD, or critical limb ischemia (CLI). Multivariable models were designed to adjust for patient and hospital factors and examine the association between ACS and PAD severity. Of approximately 3,834,181 hospitalizations for ACS, 6.4% had PAD, 0.2% had CLI, and all others were non-PAD. After risk adjustment, in-hospital mortality was higher by 24% in PAD (adjusted odds ratio 1.24, 95% confidence interval [CI] 1.21 to 1.28) and 86% in CLI (adjusted odds ratio 1.86, 95% CI 1.62 to 2.09) compared with non-PAD. Furthermore, PAD and CLI were linked to 1.23-fold (95% CI 1.20 to 1.26) and 1.67-fold (95% CI 1.45 to 1.86) greater odds of cardiogenic shock compared with non-PAD. Additionally, PAD and CLI were linked with higher odds of mechanical circulatory support usage, cardiac arrest and acute kidney injury compared with non-PAD. Lastly, duration of hospital stay, hospitalization costs and odds of non-home discharge and 30-day readmissions were greater in patients with PAD and CLI compared with non-PAD. PAD severity was associated with worse clinical outcomes in patients with ACS, including in-hospital mortality and resource utilization.

Demystifying the association of center-level operative trauma volume and outcomes of emergency general surgery.

BACKGROUND: Recent studies have demonstrated a positive volume-outcome relationship in emergency general surgery. Some have advocated for the sub-specialization of emergency general surgery independent from trauma. We hypothesized inferior clinical outcomes of emergency general surgery with increasing center-level operative trauma volume, potentially attributable to overall hospital quality. METHODS: Adults (≥18 years) undergoing complex emergency general surgery operations (large and small bowel resection, repair of perforated peptic ulcer, lysis of adhesions, laparotomy) were identified in the 2016 to 2020 Nationwide Readmissions Database. Multivariable risk-adjusted models were developed to evaluate the association of treatment at a high-volume trauma center (reference: low-volume trauma center) with clinical and financial outcomes after emergency general surgery. To evaluate hospital quality, mortality among adult hospitalizations for acute myocardial infarction was assessed by hospital trauma volume. RESULTS: Of an estimated 785,793 patients undergoing a complex emergency general surgery operation, 223,116 (28.4%) were treated at a high-volume trauma center. Treatment at a high-volume trauma center was linked to 1.19 odds of in-hospital mortality (95% confidence interval 1.12-1.27). Although emergency general surgery volume was associated with decreasing predicted risk of mortality, increasing trauma volume was linked to an incremental rise in the odds of mortality after emergency general surgery. Secondary analysis revealed increased mortality for admissions for acute myocardial infarction with greater trauma volume. CONCLUSION: We note increased mortality for emergency general surgery and acute myocardial infarction in patients receiving treatment at high-volume trauma centers, signifying underlying structural factors to broadly affect quality. Thus, decoupling trauma and emergency general surgery services may not meaningfully improve outcomes for emergency general surgery patients. Our findings have implications for the evolving specialty of emergency general surgery, especially for the safety and continued growth of the acute care surgery model.

Trends in the adoption of diverting loop ileostomy for acute complicated diverticulitis in the United States.

BACKGROUND: Acute complicated diverticulitis poses a substantial burden to individual patients and the health care system. A significant proportion of the cases necessitate emergency operations. The choice between Hartmann's procedure and primary anastomosis with diverting loop ileostomy remains controversial. METHODS: Using American College of Surgeons National Surgical Quality Improvement Program patient user file data from 2012 to 2020, patients undergoing Hartmann's procedure and primary anastomosis with diverting loop ileostomy for nonelective sigmoidectomy for complicated diverticulitis were identified. Major adverse events, 30-day mortality, perioperative complications, operative duration, reoperation, and 30-day readmissions were assessed. RESULTS: Of 16,921 cases, 6.3% underwent primary anastomosis with diverting loop ileostomy, showing a rising trend from 5.3% in 2012 to 8.4% in 2020. Primary anastomosis with diverting loop ileostomy patients, compared to Hartmann's procedure, had similar demographics and fewer severe comorbidities. Primary anastomosis with diverting loop ileostomy exhibited lower rates of major adverse events (24.6% vs 29.3%, P = .001). After risk adjustment, primary anastomosis with diverting loop ileostomy had similar risks of major adverse events and 30-day mortality compared to Hartmann's procedure. While having lower odds of respiratory (adjusted odds ratio 0.61, 95% confidence interval 0.45-0.83) and infectious (adjusted odds ratio 0.78, 95% confidence interval 0.66-0.93) complications, primary anastomosis with diverting loop ileostomy was associated with a 36-minute increment in operative duration and increased odds of 30-day readmission (adjusted odds ratio 1.30, 95% confidence interval 1.07-1.57) compared to Hartmann's procedure. CONCLUSION: Primary anastomosis with diverting loop ileostomy displayed comparable odds of major adverse events compared to Hartmann's procedure in acute complicated diverticulitis while mitigating infectious and respiratory complication risks. However, primary anastomosis with diverting loop ileostomy was associated with longer operative times and greater odds of 30-day readmission. Evolving guidelines and increasing primary anastomosis with diverting loop ileostomy use suggest a shift favoring primary anastomosis, especially in complicated diverticulitis. Future investigation of disparities in surgical approaches and patient outcomes is warranted to optimize acute diverticulitis care pathways.

Income-Based Disparities in Outcomes Following Pediatric Appendectomy: A National Analysis.

BACKGROUND: Appendectomy remains a common pediatric surgical procedure with an estimated 80,000 operations performed each year. While prior work has reported the existence of racial disparities in postoperative outcomes, we sought to characterize potential income-based inequalities using a national cohort. METHODS: All non-elective pediatric (<18 years) hospitalizations for appendectomy were tabulated in the 2016-2020 National Inpatient Sample. Only those in the highest (HI) and lowest income (LI) quartiles were considered for analysis. Multivariable regression models were developed to assess the independent association of income and postoperative major adverse events (MAE). RESULTS: Of an estimated 87,830 patients, 36,845 (42.0%) were HI and 50,985 (58.0%) were LI. On average, LI patients were younger (11 [7-14] vs 12 [8-15] years, P < .001), more frequently insured by Medicaid (70.7 vs 27.3%, P < .05), and more commonly of Hispanic ethnicity (50.8 vs 23.4%, P < .001). Following risk adjustment, the LI cohort was associated with greater odds of MAE (adjusted odds ratio [AOR] 1.30 95% confidence interval [CI] 1.06-1.64). Specifically, low-income status was linked with increased odds of infectious (AOR 1.65, 95% CI 1.12-2.42) and respiratory (AOR 1.67, 95% CI 1.06-2.62) complications. Further, LI was associated with a $1670 decrement in costs ([2220-$1120]) and a +.32-day increase in duration of stay (95% CI [.21-.44]). CONCLUSION: Pediatric patients of the lowest income quartile faced increased risk of major adverse events following appendectomy compared to those of highest income. Novel risk stratification methods and standardized care pathways are needed to ameliorate socioeconomic disparities in postoperative outcomes.

Hospital Quality Mediates Impact of Care Fragmentation Following Elective Colectomy.

BACKGROUND: Readmission at a non-index hospital, or care fragmentation (CF), has been previously linked to greater morbidity and resource utilization. However, a contemporary evaluation of the impact of CF on readmission outcomes following elective colectomy is lacking. We additionally sought to evaluate the role of hospital quality in mediating the effect of CF. METHODS: All records for adults undergoing elective colectomy were tabulated from the 2016 to 2020 Nationwide Readmissions Database. Patients readmitted non-electively within 30 days to a non-index center comprised the CF cohort (others: Non-CF). Hierarchical mixed-effects models were constructed to ascertain risk-adjusted rates of major adverse events (MAEs, a composite of in-hospital mortality and any complication) attributable to center-level effects. Hospitals with risk-adjusted MAE rates ≥50th percentile were considered Low-Quality Hospitals (LQHs) (others: High-Quality Hospitals [HQHs]). RESULTS: Of 68,185 patients readmitted non-electively within 30 days, 8968 (13.2%) were categorized as CF. On average, CF was older, of greater comorbidity burden, and more often underwent colectomy for cancer, relative to Non-CF. Following risk adjustment, CF remained independently associated with greater likelihood of MAE (adjusted odds ratio [AOR] 1.16, 95% Confidence Interval [CI] 1.05-1.27) and per-patient expenditures (ß+$2,280, CI +$1080-3490). Further, readmission to non-index LQH was linked with significantly increased odds of MAE, following initial care at HQH (AOR 1.43, CI 1.03-1.99) and LQH (AOR 1.72, CI 1.30-2.28; Reference: Non-CF). CONCLUSIONS: Care fragmentation was associated with greater morbidity and resource utilization at readmission following elective colectomy. Further, rehospitalization at non-index LQH conferred significantly inferior outcomes. Novel efforts are needed to improve continuity of care.

Open Versus Minimally Invasive Emergent Colectomy for Diverticulitis.

BACKGROUND: The role of minimally invasive surgery (MIS) in the acute management of diverticulitis remains controversial. Using a national cohort, we examined the relationship between operative approaches with acute clinical and financial outcomes. METHODS: Adults undergoing emergent colectomy for diverticulitis were tabulated from the 2015-2020 American College of Surgeons National Surgical Quality Improvement Program. Regression models were developed to analyze the association between open and MIS approaches with major adverse events (MAE), as well as secondary endpoints. A subgroup analysis was conducted to compare outcomes between open and MIS requiring conversion to open (CTO). RESULTS: Of 9194 patients, 1580 (17.3%) underwent MIS colectomy. The proportion of MIS resection increased from 15.1% in 2015 to 19.1% in 2020 (nptrend<.001). Compared to Open, MIS patients were younger, equally likely to be female, had a lower proportion of patients with ASA class ≥3, and a higher BMI. Preoperatively, MIS patients were less frequently diagnosed with sepsis. Following adjustment with open as reference, MIS approach had reduced odds of MAE (AOR .56), ostomy creation (AOR .12), shorter postoperative length of stay (LOS; ß -1.63), and a lower likelihood of nonhome discharge (AOR .45, all P < .001). Additionally, CTO was linked to decreased likelihood of MAE (AOR .78, P = .01), ostomy creation (AOR .02, P < .001), comparable LOS (ß -.46, P = .41), and reduced odds of nonhome discharge (AOR .58, P < .001), relative to open. DISCUSSION: Compared to planned open colectomy, MIS resection was associated with improved clinical and financial outcomes, even in cases of CTO. Our findings suggest that whenever possible, MIS should be attempted first in emergent colectomy for diverticulitis. Nevertheless, future prospective studies are likely needed to further elucidate specific patient and clinical factors.

Association of rurality with short-term outcomes of peripheral vascular trauma.

BACKGROUND: Peripheral vascular trauma is a major contributing factor to long-term disability and mortality among patients with traumatic injuries. However, an analysis focusing on individuals at a high risk of experiencing limb loss due to rural and urban peripheral vascular trauma is lacking. METHOD: This was a retrospective analysis of the 2016 to 2020 Nationwide Readmissions Database. Patients (≥18 years) undergoing open or endovascular procedures after admission for peripheral vascular trauma were identified using the 2016 to 2020 Nationwide Readmissions Database. Patients from rural regions were considered Rural, whereas the remainder comprised Urban. The primary outcome of the study was primary amputation. Multivariable regression models were developed to evaluate rurality with outcomes of interest. RESULTS: Of 29,083 patients, 4,486 (15.6%) were Rural. Rural were older (41 [28-59] vs 37 [27-54] years, P < .001), with a similar distribution of female sex (23.0 vs 21.3%, P = .09) and transfers from other facilities (2.8 vs 2.5%, P = .34). After adjustment, Rural status was not associated with the odds of mortality (P = .82), with urban as reference. Rural status was, however, associated with greater odds of limb amputation (adjusted odds ratio 1.85, 95% confidence interval 1.47-2.32) and reduced index hospitalization cost by $7,100 (95% confidence interval $3,500-10,800). Additionally, compared to patients from urban locations, rurality was associated with similar odds of non-home discharge and 30-day readmission. Over the study period, the marginal effect of rurality on the risk-adjusted rates of amputation significantly increased (P < .001). CONCLUSION: Patients who undergo peripheral vascular trauma management in rural areas appear to increasingly exhibit a higher likelihood of amputation, with lower incremental costs and a lower risk of 30-day readmission. These findings underscore disparities in access to optimal trauma vascular care as well as limited resources in rural regions.

Association of prior bariatric surgery with outcomes following emergency general surgery.

BACKGROUND: Despite the favorable outcomes and safety profile associated with metabolic and bariatric surgery (MBS), complications may occur postoperatively, necessitating emergency general surgery (EGS) intervention. OBJECTIVES: To evaluate the association of outcomes in patients with prior MBS following EGS interventions. SETTING: Academic, University-affiliated; USA. METHODS: All adults undergoing nonelective EGS operations were identified using the 2016 to 2020 Nationwide Readmission Database. Patients with a history of MBS were subsequently categorized as Bariatric, with the remainder of patients as NonBariatric. The primary outcome of interest was in-hospital mortality, while perioperative complications, length of stay (LOS), hospitalization costs, non-home discharge, and 30-day readmission were secondarily assessed. Multivariable regression models were developed to evaluate the association of history of MBS with outcomes of interest. RESULTS: Of an estimated 632,375 hospitalizations for EGS operations, 29,112 (4.6%) had a history of MBS. Compared to Nonbariatric, Bariatric were younger, more frequently female and more commonly had severe obesity. Following risk adjustment, Bariatric had significantly lower odds of in-hospital mortality (AOR .83, 95%CI .71-.98). Compared to others, Bariatric had reduced LOS by .5 days (95%CI .4-.7) and hospitalization costs by $1600 (95%CI $900-2100). Patients with prior MBS had reduced odds of nonhome discharge (AOR .89, 95%CI .85-.93) and increased likelihood of 30-day readmissions (AOR 2.32, 95%CI 1.93--2.79) following EGS. CONCLUSIONS: Prior MBS is associated with decreased mortality and perioperative complications as well as reduced resource utilization in select EGS procedures. Our findings suggest that patients with a history of MBS can be managed effectively by acute surgical interventions.

Contemporary national outcomes of hyperbaric oxygen therapy in necrotizing soft tissue infections.

BACKGROUND: The role of hyperbaric oxygen therapy (HBOT) in necrotizing soft tissue infections (NSTI) is mainly based on small retrospective studies. A previous study using the 1998-2009 National Inpatient Sample (NIS) found HBOT to be associated with decreased mortality in NSTI. Given the argument of advancements in critical care, we aimed to investigate the continued role of HBOT in NSTI. METHODS: The 2012-2020 National Inpatient Sample (NIS) was queried for NSTI admissions who received surgery. 60,481 patients between 2012-2020 were included, 600 (<1%) underwent HBOT. Primary outcome was in-hospital mortality. Secondary outcomes included amputation, hospital length of stay, and costs. A multivariate model was constructed to account for baseline differences in groups. RESULTS: Age, gender, and comorbidities were similar between the two groups. On bivariate comparison, the HBOT group had lower mortality rate (<2% vs 5.9%, p<0.001) and lower amputation rate (11.8% vs 18.3%, p<0.001) however, longer lengths of stay (16.9 days vs 14.6 days, p<0.001) and higher costs ($54,000 vs $46,000, p<0.001). After multivariate analysis, HBOT was associated with decreased mortality (Adjusted Odds Ratio (AOR) 0.22, 95% CI 0.09-0.53, P<0.001) and lower risk of amputation (AOR 0.73, 95% CI 0.55-0.96, P = 0.03). HBO was associated with longer stays by 1.6 days (95% CI 0.4-2.7 days) and increased costs by $7,800 (95% CI $2,200-$13,300), they also had significantly lower risks of non-home discharges (AOR 0.79, 95%CI 0.65-0.96). CONCLUSIONS: After correction for differences, HBOT was associated with decreased mortality, amputations, and non-home discharges in NSTI with the tradeoff of increase to costs and length of stay.

Prior bariatric surgery is associated with lower mortality and resource utilization following small bowel obstruction.

Background: Small bowel obstruction (SBO) is a complication of bariatric surgery. However, outcomes of surgical intervention for SBO among patients with prior bariatric surgery remain ill-defined. We used a nationally representative cohort to characterize the outcomes of the SBO management approach in patients with a prior bariatric operation. Methods: All adult hospitalizations for SBO were tabulated from the 2018-2020 National Readmissions Database. Patients with a prior history of bariatric surgery comprised the Bariatric cohort (others: Non-Bariatric). Multivariable models were subsequently developed to evaluate the association of prior bariatric surgery with outcomes of interest. Results: Of an estimated 299,983 hospitalizations for SBO, 15,788 (5.3 %) had a history of prior bariatric surgery. Compared to Non-Bariatric, Bariatric patients were younger (54 [46-62] vs 57 [47-64] years, P < 0.001) and were more frequently privately insured (45.1 vs 39.4 %, P < 0.001). On average, the Bariatric more frequently underwent operative management, relative to Non-Bariatric (44.8 vs 29.7 %, P < 0.001). Following risk adjustment, among those surgically managed, Bariatric demonstrated lower odds of mortality (Adjusted Odds Ratio [AOR] 0.69, 95 % Confidence Interval [CI] 0.55-0.87) compared to Non-Bariatric. Bariatric also demonstrated lower odds of infectious and renal complications. Furthermore, the Bariatric cohort had lower costs, length of stay, and non-home discharge. Conclusions: Patients with prior bariatric surgery demonstrated a lower likelihood of mortality, decreased complications, and reduced resource utilization, relative to others. As the incidence of bariatric surgery continues to rise, future work is needed to minimize the incidence of SBO among these patients, especially in the current era of value-based healthcare.

National outcomes of expedited discharge following esophagectomy for malignancy.

BACKGROUND: Expedited discharge following esophagectomy is controversial due to concerns for higher readmissions and financial burden. The present study aimed to evaluate the association of expedited discharge with hospitalization costs and unplanned readmissions following esophagectomy for malignant lesions. METHODS: Adults undergoing elective esophagectomy for cancer were identified in the 2014-2019 Nationwide Readmissions Database. Patients discharged by postoperative day 7 were considered Expedited and others as Routine. Patients who did not survive to discharge or had major perioperative complications were excluded. Multivariable regression models were constructed to assess association of expedited discharge with index hospitalization costs as well as 30- and 90-day non-elective readmissions. RESULTS: Of 9,886 patients who met study criteria, 34.6% comprised the Expedited cohort. After adjustment, female sex (adjusted odds ratio [AOR] 0.71, p = 0.001) and increasing Elixhauser Comorbidity Index (AOR 0.88/point, p<0.001) were associated with lower odds of expedited discharge, while laparoscopic (AOR 1.63, p<0.001, Ref: open) and robotic (AOR 1.67, p = 0.003, Ref: open) approach were linked to greater likelihood. Patients at centers in the highest-tertile of minimally invasive esophagectomy volume had increased odds of expedited discharge (AOR 1.52, p = 0.025, Ref: lowest-tertile). On multivariable analysis, expedited discharge was independently associated with an $8,300 reduction in hospitalization costs. Notably, expedited discharge was associated with similar odds of 30-day (AOR 1.10, p = 0.40) and 90-day (AOR 0.90, p = 0.70) unplanned readmissions. CONCLUSION: Expedited discharge after esophagectomy was associated with decreased costs and unaltered readmissions. Prospective studies are necessary to robustly evaluate whether expedited discharge is appropriate for select patients undergoing esophagectomy.

Hospital-level variation in hospitalization costs for spinal fusion in the United States.

BACKGROUND: With a growing emphasis on value of care, understanding factors associated with rising healthcare costs is increasingly important. In this national study, we evaluated the degree of center-level variation in the cost of spinal fusion. METHODS: All adults undergoing elective spinal fusion were identified in the 2016 to 2020 National Inpatient Sample. Multilevel mixed-effect models were used to rank hospitals based on risk-adjusted costs. The interclass coefficient (ICC) was utilized to tabulate the amount of variation attributable to hospital-level characteristics. The association of high cost-hospital (HCH) status with in-hospital mortality, perioperative complications, and overall resource utilization was analyzed. Predictors of increased costs were secondarily explored. RESULTS: An estimated 1,541,740 patients underwent spinal fusion, and HCH performed an average of 9.5% of annual cases. HCH were more likely to be small (36.8 vs 30.5%, p<0.001), rural (10.1 vs 8.8%, p<0.001), and located in the Western geographic region (49.9 vs 16.7%, p<0.001). The ICC demonstrated 32% of variation in cost was attributable to the hospital, independent of patient-level characteristics. Patients who received a spinal fusion at a HCH faced similar odds of mortality (0.74 [0.48-1.15], p = 0.18) and perioperative complications (1.04 [0.93-1.16], p = 0.52), but increased odds of non-home discharge (1.30 [1.17-1.45], p<0.001) and prolonged length of stay (ß 0.34 [0.26-0.42] days, p = 0.18). Patient factors such as gender, race, and income quartile significantly impacted costs. CONCLUSION: The present analysis identified 32% of the observed variation to be attributable to hospital-level characteristics. HCH status was not associated with increased mortality or perioperative complications.

Percutaneous cholecystostomy tube placement as a bridge to cholecystectomy for grade III acute cholecystitis: A national analysis.

Introduction: Percutaneous cholecystostomy (PCT) is an alternative to cholecystectomy (CCY) in high-risk surgical candidates with severe acute cholecystitis. A subset of these patients ultimately undergo delayed CCY. We therefore compared outcomes of delayed CCY in patients with grade III acute cholecystitis who received a PCT on index admission, to those who did not. Methods: Non-elective adult hospitalizations for grade III acute cholecystitis that underwent delayed CCY were identified in the 2016-2020 Nationwide Readmission Database. Patients who received a PCT during their index admission comprised the PCT group (others: Non-PCT). Outcomes were assessed for the CCY hospitalization. Entropy balancing was used to generate sample weights to adjust for differences in baseline characteristics. Regression models were created to evaluate the association between PCT and the outcomes of interest. Results: Of an estimated 13,782 patients, 13.3 % comprised PCT. Compared to Non-PCT, PCT were older (71.1 ± 13.1 vs 67.4 ± 15.3 years) and more commonly in the highest income quartile (22.5 vs 16.1 %, both p < 0.001). After risk adjustment, PCT was associated with reduced odds of respiratory (AOR 0.67, CI 0.54-0.83) and infectious (AOR 0.77, CI 0.62-0.96) complications after eventual CCY. Finally, PCT had comparable pLOS (ß +0.31, CI [-0.14, 0.77]) and operative hospitalization costs (ß $800, CI [-2300, +600]). Conclusion: In the present study, PCT was associated with decreased odds of perioperative complications and comparable resource utilization upon readmission CCY. Our findings suggest that PCT may be helpful in bridging patients with grade III acute cholecystitis to eventual CCY.

National analysis of racial disparities in emergent surgery for colorectal cancer.

Background: Racial disparities in access to preoperative evaluation for colorectal cancer remain unclear. Emergent admission may indicate lack of access to timely care. The present work aimed to evaluate the association of admission type with race among patients undergoing colorectal cancer surgery. Methods: All adults undergoing resection for colorectal cancer in 2011-2020 National Inpatient Sample were identified. Multivariable regression models were developed to examine the association of admission type with race. Primary outcome was major adverse events (MAE), including mortality and complications. Secondary outcomes included costs and length of stay (LOS). Interaction terms between year, admission type, and race were used to analyze trends. Results: Of 722,736 patients, 67.6 % had Elective and 32.4 % Emergent admission. Black (AOR 1.38 [95 % CI 1.33-1.44]), Hispanic (1.45 [1.38-1.53]), and Asian/Pacific Islander or Native American (1.25 [1.18-1.32]) race were associated with significantly increased odds of Emergent operation relative to White. Over the study period, non-White patients consistently comprised over 5 % greater proportion of the Emergent cohort compared to Elective. Furthermore, Emergent admission was associated with 3-fold increase in mortality and complications, 5-day increment in LOS, and $10,100 increase in costs. MAE rates among Emergent patients remained greater than Elective with a widening gap over time. Non-White patients experienced significantly increased MAE regardless of admission type. Conclusion: Non-White race was associated with increased odds of emergent colorectal cancer resection. Given the persistent disparity over the past decade, systematic approaches to alleviate racial inequities in colorectal cancer screening and improve access to timely surgical treatment are warranted.

The Association of High-Quality Hospital Use on Health Care Outcomes for Pediatric Congenital Heart Defects in a Universal Health Care System.

INTRODUCTION: Congenital heart disease (CHD) has an incidence of 0.8% to 1.2% worldwide, making it the most common birth defect. Researchers have compared high-volume to low-volume hospitals and found significant hospital-level variation in major complications, health resource utilization, and mortality after CHD surgery. In addition, researchers found critical CHD patients at low-volume/non-teaching facilities to be associated with higher odds of inpatient mortality when compared to CHD patients at high-volume/teaching hospitals (odds ratio 1.76). We examined the effects of high-quality hospital (HQH) use on health care outcomes and health care costs in pediatric CHD care using an instrumental variable (IV) approach. MATERIALS AND METHODS: Using nationwide representative claim data from the United States Military Health System from 2016 to 2020, TRICARE beneficiaries with a diagnosis of CHD were tabulated based on relevant ICD-10 (International Classification of Diseases, 10th revision) codes. We examined the relationships between annual readmissions, annual emergency room (ER) use, and mortality and HQH use. We applied both the naive linear probability model (LPM), controlling for the observed patient and hospital characteristics, and the two-stage least squares (2SLS) model, accounting for the unobserved confounding factors. The differential distance between the patient and the closest HQH at the index date and the patient and nearest non-HQH was used as the IV. This protocol was approved by the Institutional Review Board at the University of Maryland, College Park (Approval Number: 1576246-2). RESULTS: The naive LPM indicated that HQH use was associated with a higher probability of annual readmissions (marginal effect, 18%; 95% CI, 0.12 to 0.23). The naive LPM indicated that HQH use was associated with a higher probability of mortality (marginal effect, 2.2%; 95% CI, 0.01 to 0.03). Using the differential distance of closest HQH and non-HQH, we identified a significant association between HQH use and annual ER use (marginal effect, -14%; 95% CI, -0.24 to -0.03). CONCLUSIONS: After controlling for patient-level and facility-level covariates and adjusting for endogeneity, (1) HQH use did not increase the probability of more than one admission post 1-year CHD diagnosis, (2) HQH use lowered the probability of annual ER use post 1-year CHD diagnosis, and (3) HQH use did not increase the probability of mortality post 1-year CHD diagnosis. Patients who may have benefited from utilizing HQH for CHD care did not, alluding to potential barriers to access, such as health insurance restrictions or lack of patient awareness. Although we used hospital quality rating for congenital cardiac surgery as reported by the Society of Thoracic Surgeons, the contributing data span a 4-year period and may not reflect real-time changes in center performance. Since this study focused on inpatient care within the first-year post-initial CHD diagnosis, it may not reflect the full range of health system utilization. It is necessary for clinicians and patient advocacy groups to collaborate with policymakers to promote the development of an overarching HQH designation authority for CHD care. Such establishment will facilitate access to HQH for military beneficiary populations suffering from CHD.

Outcomes of Hospitalized Injured Suspects Sustaining Gunshot Wounds From Law Enforcement Action.

BACKGROUND: Although firearms are implicated in the majority of law enforcement intervention (LEI)-related deaths, scientific research is lacking. The present study sought to characterize clinical and financial outcomes between injured suspects and other gunshot wound (GSW) patients. STUDY DESIGN: The 2016-2020 National Inpatient Sample was queried for patients ≥16 years old admitted following GSW. Patients were categorized as injured suspects (ISs) if they were injured in LEI and non-IS otherwise. The primary outcome was in-hospital mortality with complications, hospitalization duration (LOS), and costs secondarily considered. Multivariable regression models were used to adjust for patient characteristics, injury burden using the Trauma Mortality Prediction Model (TMPM), and hospital factors. RESULTS: Of 143,125 hospitalizations, 1575 (1.10%) were IS. Compared to non-IS, ISs were less frequently Black (24.4% vs 54.3%) but had a higher proportion of psychiatric conditions (19.4% vs 6.4%) (P < .05). Although having a similar requirement for major operations and TMPM score, ISs more frequently underwent thoracic (11.4% vs 4.1%) and gastrointestinal operations (33.0% vs 25.7%) (P < .05). After adjustment, IS was associated with similar odds of mortality but was associated with greater odds of cardiac complications, respiratory failure, and need for intensive care. While LOS was similar, IS was associated with greater costs (ß: +$14,300, 95% CI: 6,200-22,400). CONCLUSIONS: Suspects injured during law enforcement intervention have similar in-hospital mortality but greater complication rates and costs. Through the quantification of the clinical and financial burden of IS, our findings may help inform further policy discussions regarding use of potentially lethal force in law enforcement intervention.

National Trends and Clinical Outcomes after Scooter Injury in the US: 2016 to 2020.

BACKGROUND: In recent years, the adoption of electric scooters has been accompanied by a surge of scooter-related injuries in the US, raising concerns for their severity and associated healthcare costs. This study aimed to assess temporal trends and outcomes of scooter-related hospital admissions compared with bicycle-related hospitalizations. STUDY DESIGN: This was a retrospective cohort study using the 2016 to 2020 National Inpatient Sample for patients younger than 65 years who were hospitalized after bicycle- and scooter-related injuries. The Trauma Mortality Prediction Model was used to quantify injury severity. The primary outcomes of interest were temporal trends of micromobility injuries. In-hospital mortality, rates of long bone fracture, traumatic brain injury, paralysis, length of stay, hospitalization costs, and nonhome discharge were secondarily assessed. RESULTS: Among 92,815 patients included in the study, 6,125 (6.6%) had scooter-related injuries. Compared with patients with bicycle-related injuries, patients with scooter-related injuries were more commonly younger than 18 years (26.7% vs 16.4%, p < 0.001) and frequently underwent major operations (55.8% vs 48.1%, p < 0.001). After risk adjustment, scooter-related injuries were associated with greater risks of long bone fracture (adjusted odds ratio 1.40, 95% CI 1.15 to 1.70) and paralysis (adjusted odds ratio 2.06, 95% CI 1.16 to 3.69) compared with bicycle-related injuries. Additionally, patients with bicycle- or scooter-related injuries had comparable index hospitalization durations of stay and costs. CONCLUSIONS: The prevalence and severity of scooter-related injuries have significantly increased in the US, thereby attributing to a substantial cost burden on the healthcare system. Multidisciplinary efforts to inform safety policies and enact targeted interventions are warranted to reduce scooter-related injuries.

Association of Early Rib Plating on Clinical and Financial Outcomes: A National Analysis.

BACKGROUND: With reported improvements in patient outcomes, surgical stabilization of rib fractures (SSRF) has been increasingly adopted. While institutional series have sought to define the role of early SSRF, large scale analysis remains lacking. The present study evaluated clinical and financial outcomes of SSRF in a nationally representative cohort. METHODS: Patients (≥16 years) admitted with multiple rib fractures were identified using the 2016-2020 National Inpatient Sample. Those who underwent rib plating >14 days following admission were omitted. Using restricted cubic spline analysis, patients who underwent SSRF within 2 days of hospitalization were classified as Expedited while fixation >2 days were deemed Routine. Multivariable regressions were used to evaluate the association of operative timing on outcomes of interest. RESULTS: Of 8150 patients meeting final inclusion criteria, 4090 (50.2%) were Expedited. Compared to Routine, Expedited tended to be older but were of comparable race, primary payer, and income quartile. Traumatic mechanism was also similar but rates of concomitant sternal fracture as well as intra-abdominal and cardiac injuries were higher in Routine. After adjustment, Expedited was associated with lower odds of respiratory complications, which included need for mechanical ventilation, prolonged mechanical ventilation, and pneumonia, compared to Routine. Expedited was associated with similar hospitalization duration but had lower incremental costs (ß: -$19.1 K, 95% CI: -24.1 to -14.2). DISCUSSION: Early SSRF was associated with lower likelihood of a number of respiratory complications and in-hospital costs. While patient selection criteria may limit our findings, expeditious fixation may limit morbidity while enhancing value of care.
