Hospital Readmission Following Surgery for Gastric Cancer: Frequency, Timing, Etiologies, and Survival

Lactate Dehydrogenase and Risk of Readmission with Gastric Cancer: A Propensity Score Matching Analysis

PURPOSE

Readmission is one of the measures of quality of care and potential costs. This study aimed to determine whether lactate dehydrogenase (LDH) is associated with an increased risk of 30-day readmission in gastric cancer.

METHODS

We performed a retrospective study of patients who underwent radical gastrectomy for gastric cancer at our institution between July 2014 and May 2018. Balanced cohorts were created by propensity score matching (PSM) with a 1:1 ratio to generate the elevated LDH (ELDH) group (n = 151) and the low LDH group (Control) (n = 302). To determine the incidence, causes, and risk factors of 30-day readmission, subgroup analyzes were performed and used to develop an efficient prediction model.

RESULTS

A total of 788 patients met the criteria to be included in the study. The cutoff value for serum LDH was 215.5. After PSM, a total of 302 patients were matched in pairs (ELDH group, n = 151, Control group, n = 151). ELDH levels had a higher risk of readmission (p = 0.005, Odds ratio 3.768, 95% confidence interval 1.493-9.510). The pre-match 30-day readmission rate was 7.2 percent, and common causes of post-match readmission included infection-related symptoms, gastrointestinal symptoms, and gastrointestinal bleeding.

CONCLUSIONS

Patients with preoperative ELDH levels, postoperative complications, and high preoperative American Society of Anesthesiologists Scores had a higher risk of readmission 30 days after surgery.

Improving Gastrointestinal Cancer Care by Enhanced Recovery Protocol Implementation

Background

Enhanced recovery protocols (ERPs) have become the standard of care for patients undergoing elective small bowel surgeries but have not yet been adequately studied in community hospitals. In this study, a multidisciplinary ERP was developed and implemented at a community hospital to include minimal anesthesia, early ambulation and enteral alimentation, and multimodal analgesia. The aim of this study was to determine the effects of the ERP on postoperative length of stay (LOS), readmission (RA) rates following bowel surgery, and postoperative outcomes.

Methods

The study design was a retrospective review of patients undergoing major bowel resection at Holy Cross Hospital (HCH) from January 1, 2017 to December 31, 2017. Patient charts for diagnostic-related group (DRG) 329, 330, and 331 were retrospectively reviewed at HCH in 2017 to compare outcomes in ERP versus non-ERP cases. The Medicare claims database (CMS) was also retrospectively reviewed to compare HCH data to the national average LOS and RA for the same DRG codes. Mean values for LOS and RA were statistically compared to determine significant differences between ERP versus non-ERP patients at HCH and national CMS data versus HCH patients.

Results

LOS was analyzed for each DRG at HCH. At HCH, for DRG 329, the mean LOS for non-ERP was 13.0833 days (n = 12) versus 3.375 days (n = 8) (P ≤ 0.001) for ERP. For DRG 330, the mean LOS for non-ERP was 10.861 days (n = 36) versus 4.583 days (n = 24) (P ≤ 0.001) for ERP. For DRG 331, the mean LOS for non-ERP was 7.272 days (n = 11) versus 3.348 days (n = 23) (P = 0.004) for ERP. LOS was also compared to national CMS data. The LOS at HCH for DRG 329 improved from the 10th to 90th percentile (n = 238,907); DRG 330 improved from the 10th to the 72nd percentile (n = 285,423); DRG 331 improved from 10th to 54th percentile (n = 126,941) (P < 0.001). The RA at HCH in ERP and non-ERP cases was 3% at 30 and 90 days. CMS RA for DRG 329 was 25.1% at 90 days and 9.9% at 30 days; DRG 330 RA was 18.3% at 90 days and 6.6% at 30 days; DRG 331 RA was 11% at 90 days and 3.9% at 30 days.

Conclusion

Implementation of ERP following bowel surgery at HCH significantly improved outcomes, in comparison to non-ERP cases, national CMS data, and Humana data. Further research on ERP for other fields and its impact on outcomes in other community settings is recommended.

Readmissions From Venous Thromboembolism After Complex Cancer Surgery

IMPORTANCE

Venous thromboembolism (VTE) is a major cause of preventable morbidity and mortality after cancer surgery. Venous thromboembolism events that are significant enough to require hospital readmission are potentially life threatening, yet data regarding the frequency of these events beyond the 30-day postoperative period remain limited.

OBJECTIVE

To determine the rates, outcomes, and predictive factors of readmissions owing to VTE up to 180 days after complex cancer operations, using a national data set.

DESIGN, SETTING, AND PARTICIPANTS

A retrospective cohort study of the 2016 Nationwide Readmissions Database was performed to study adult patients readmitted with a primary VTE diagnosis. Data obtained from 197 510 visits for 126 104 patients were analyzed. This was a multicenter, population-based, nationally representative study of patients who underwent a complex cancer operation (defined as cystectomy, colectomy, esophagectomy, gastrectomy, liver/biliary resection, lung/bronchus resection, pancreatectomy, proctectomy, prostatectomy, or hysterectomy) from January 1 through September 30, 2016, for a corresponding cancer diagnosis.

EXPOSURES

Readmission with a primary diagnosis of VTE.

MAIN OUTCOMES AND MEASURES

Proportion of 30-, 90-, and 180-day VTE readmissions after complex cancer surgery, factors associated with readmissions, and outcomes observed during readmission visit, including mortality, length of stay, hospital cost, and readmission to index vs nonindex hospital.

RESULTS

For the 126 104 patients included in the study, 30-, 90-, and 180-day VTE-associated readmission rates were 0.6% (767 patients), 1.1% (1331 patients), and 1.7% (1449 of 83 337 patients), respectively. A majority of patients were men (58.7%), and the mean age was 65 years (SD, 11.5 years). For the 1331 patients readmitted for VTE within 90 days, 456 initial readmissions (34.3%) were to a different hospital than the index surgery hospital, median length of stay was 5 days (IQR, 3-7 days), median cost was $8102 (IQR, $5311-$10 982), and 122 patients died (9.2%). Independent factors associated with readmission included type of operation, scores for severity and risk of mortality, age of 75 to 84 years (odds ratio [OR], 1.30; 95% CI, 1.02-1.78), female sex (OR, 1.23; 95% CI, 1.11-1.37), nonelective index admission (OR, 1.31; 95% CI, 1.03-1.68), higher number of comorbidities (OR, 1.30; 95% CI, 1.06-1.60), and experiencing a major postoperative complication during the index admission (OR, 2.08; 95% CI, 1.85-2.33).

CONCLUSIONS AND RELEVANCE

In this cohort study, VTE-related readmissions after complex cancer surgery continued to increase well beyond 30 days after surgery. Quality improvement efforts to decrease the burden of VTE in postoperative patients should measure and account for these late VTE-related readmissions.

Analysis of Rates, Causes, and Risk Factors for 90-Day Readmission After Surgery for Large Hiatal Hernia: A Two-Center Study

Background: Hospital readmissions have become a more examined indicator of surgical care delivery and quality. There is scarcity of data in the literature on the rate, risk factors, and most common reasons of readmission following major hiatal hernia surgery. The primary endpoint was 90-day readmission after surgery for large hiatal hernia. Secondary endpoint was to examine which characteristics related with a higher risk of readmission. Methods: A retrospective review of two distinct institutional databases was performed for patients who had surgery for a large hiatal hernia between January 2012 and December 2019. Demographic, perioperative, and outpatient data were collected from the medical record. Results: A total of 71 patients met the inclusion criteria, most of them suffering from a type III hernia (66.2%). Mean operative time was 146 (±56.5) minutes and median length of stay (LOS) was 6 days (interquartile range = 3). The overall morbidity was 21.1% and the in-hospital mortality was 1.4%. The 30- and 90-day readmission rates were 7% and 8.5%, respectively. The mean time to readmission was 14.3 (±15.6) days. The reasons for 90-day hospital readmission were dysphagia (50%), pneumonia (16.7%), congestive heart failure (16.7%), and bowel obstruction (16.7%). Grade of esophagitis ≥2, presence of Barrett's esophagus, and LOS longer than 8 days were significant risk factors for unplanned readmission within 90 days. Conclusion: We observed that about 6 out of 71 patients who had surgery readmitted within 90 days (8.5%). Readmissions were most often linked to esophagitis ≥2, presence of Barrett's esophagus, and LOS longer than 8 days. These findings point to the necessity for focused treatments before, during, and after hospitalization to decrease morbidity and extra costs in this high-risk population.

Predicting Early and Late Readmissions Following Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy

Background

Postoperative readmissions not only burden the healthcare system but may also affect clinical outcomes of cancer patients. Despite this, little is known about readmissions after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), or their impact on survival outcomes.

Patients and Methods

A single-institution retrospective cohort study of CRS-HIPEC procedures from April 2001 and September 2019 was performed. Early readmission (ERA) was defined as hospitalization within 30 days of discharge post-CRS/HIPEC, while late readmission (LRA) was defined as hospitalization between day 31 and 90 after discharge. Patient demographic, oncological, and perioperative factors were analyzed to identify predictors of readmission, and comparison of survival outcomes was performed.

Results

Overall, 342 patients who underwent CRS-HIPEC were included in the study. The incidence of ERA and LRA was 18.5% and 7.4%, respectively. High-grade postoperative complication was the only independent predictor of ERA (HR 3.64, 95% CI 1.47–9.02), while comorbid hypertension (HR 2.71, 95% CI 1.17–6.28) and stoma creation (HR 2.83, 95% CI 1.23–6.50) were independent predictors for LRA. Patients with readmission had significantly worse disease-free survival than patients who had no readmission (NRA) (LRA 1.1 years, ERA 1.2 years, NRA 1.8 years, p = 0.002), and patients with LRA had worse median overall survival (2.1 years) than ERA patients (3.3 years) or patients without readmission (4.4 years) (p < 0.001).

Conclusions

Readmission following CRS-HIPEC is associated with adverse survival outcomes. In particular, LRA may portend worse prognosis than ERA.

Diffuse Reduction of Spleen Density Is an Independent Predictor of Post-Operative Outcomes After Curative Gastrectomy in Gastric Cancer: A Multi-Center Study

Objectives: The present study aimed to explore the association between spleen density and post-operative outcomes of patients after curative gastrectomy.

Methods: From June 2014 to December 2015, we conducted a retrospective study to analyze pertinent clinical data from gastric cancer patients who underwent gastrectomy at the First and the Second Affiliated Hospital of Wenzhou Medical University. Spleen density was determined via computed tomography scans. Univariate and multivariate analyses were performed to determine the risk factors associated with post-operative outcomes after gastric cancer surgery.

Results: Three hundred and ninety five patients were included, of whom 98 (24.8%) were defined as having a diffuse reduction of spleen density based on diagnostic cutoff values (spleen density ≤43.89 HU). Multivariate analysis revealed diffuse reduction of spleen density as an independent risk factor for post-operative complications and long-term overall survival.

Conclusions: Spleen density can predict severe postoperative complications and long-term overall survival in gastric cancer patients. As an imaging evaluation method, spleen density is a novel tool can be used in clinical as a prognostic predictor for patients with gastric cancer.

Readmission Adversely Affects Survival in Surgical Rectal Cancer Patients

BACKGROUND

Readmission has received attention as a potential healthcare quality metric. No studies have investigated the relationship between readmission and survival in patients undergoing rectal cancer surgery. The aims of this study were to identify factors associated with 30-day readmission after rectal cancer surgery and to determine the impact of readmission on overall survival (OS).

METHODS

Patients who underwent surgical treatment for rectal/rectosigmoid adenocarcinoma stages I-IV were identified using the National Cancer Database (2004-2014). Multivariable logistic regression was used to identify factors for readmission. 2:1 nearest neighbor caliper matching without replacement was used to ensure similarity of patients being compared. Survival analyses were performed using Kaplan-Meier method along with log-rank test and Cox proportional hazards model.

RESULTS

Of 110,167 patients, 7045 (6.39%) were readmitted. Factors associated with readmission included higher Charlson comorbidity score, non-private or no insurance, procedure type, hospitals in the Northeast, South, and Midwest regions, and prolonged length of stay. Within the matched cohort (13,756 non-readmitted and 6878 readmitted), readmitted patients had worse 5- and 10-year OS regardless of cancer stage (p < 0.001) and procedure type. Five- and 10-year OS were 58.98% and 41.01% for readmitted patients, 64.96% and 43.50% for non-readmitted patients. Readmitted patients had shorter OS by 13.14 months and increased risk of mortality (HR 1.20, 95% CI 1.15-1.25, p < 0.001).

CONCLUSIONS

Thirty-day readmission after rectal cancer surgery is associated with decreased OS. Efforts to reduce readmissions should be considered to advance cancer care and enhance the potential for improved patient survival.

Risk factors of the postoperative 30-day readmission of gastric cancer surgery after discharge: A PRISMA-compliant systematic review and meta-analysis

BACKGROUND

Readmission is a common postoperative adverse event. This study aimed to analyze potential risk factors for the incidence of postoperative 30-day readmission after discharge for gastric cancer patients with surgical treatment.

METHODS

Those studies that reported the risk factors of gastric cancer patients who have a postoperative 30-day readmission were identified systematically from the PubMed, Cochrane, and Embase databases through July 2018. A systematic review and meta-analysis was performed to estimate the risk factors of postoperative 30-day readmission after gastric cancer surgery.

RESULTS

Ultimately, 6 studies with 12,586 gastric cancer patients were included in the present study. There were 1473 (11.7%) patients who had postoperative 30-day readmission and 12,586 (88.3%) patients without 30-day postoperative readmission. A greater proportion of the readmission group had cardiovascular comorbidity (P < .001), pulmonary comorbidity (P < .001), and diabetes mellitus (P = .020) than the nonreadmission group. Furthermore, more patients in the readmission group had total gastrectomy (P < .001), combined organ resection (P < .001) and postoperative complications (P < .001) than did patients in the nonreadmission group. Nonhome discharge (odds ratio [OR] 1.580, P = .002), diabetes mellitus (OR 1.181, P = .044), postoperative complications (OR 2.656, P = .006), total gastrectomy (OR 2.242, P < .001), and combined organ resection (OR 1.534, P < .001) were independent risk factors for postoperative readmission.

CONCLUSION

Postoperative readmission is influenced by the synthetic action of preparative, intraoperative, and postoperative factors, such as diabetes mellitus, total gastrectomy, combined organ resection, nonhome discharge, and postoperative complications. Extra attention should be paid to those patients with high risk factors during the postoperative follow-up and recovery periods.

Risk factors for 30-day hospital readmission after radical gastrectomy: a single-center retrospective study

BACKGROUND

Hospital readmission is gathering greater attention as a measure of health care quality. The introduction of fast-track surgery has led to shorter lengths of hospitalization without increasing the risk of postoperative complications and readmission. The collection of comprehensive readmission data is essential for the further improvement of patient care. The aim of the present study is to evaluate the risk factors for readmission within 30 days of discharge after gastrectomy.

METHODS

A total of 1929 patients who underwent radical gastrectomy at Shizuoka Cancer Center were included in this study. A risk analysis with a stepwise logistic regression model was conducted to identify the risk factors for 30-day hospital readmission.

RESULTS

The 30-day readmission rate was 2.70%. Common causes of readmission were an intolerance of oral intake and the presence of an intra-abdominal abscess. The C reactive protein (CRP) level on postoperative day (POD) 3 was significantly higher in the readmitted group; however, the other surgical outcomes, including the incidence of postoperative complications, did not differ to a statistically significant extent. The stepwise logistic regression analysis revealed that CRP on POD3 ≥ 12 mg/dl [odds ratio (OR) 2.08, 95% confidence interval (CI) 1.09-3.95, p = 0.025], laparoscopic surgery (OR 2.25, 95% CI 1.17-4.31, p = 0.015), and TG (OR 2.23, 95% CI 1.17-4.78, p = 0.023) were found to be independent risk factors for readmission.

CONCLUSIONS

CRP on POD3 ≥ 12 mg/dl, laparoscopic surgery, and TG were identified as independent risk factors for readmission.

Is home parenteral nutrition safe for cancer patients? Positive effects and potential catheter-related complications: A systematic review

PURPOSE

Total Parenteral Nutrition began to be applied frequently in the houses of patients starting from the 1990s and is stated in literature as Home Parenteral Nutrition (HPN). The purpose of this review is to answer the question of whether or not HPN is safe for cancer patients.

METHODS

Searches were conducted in Cochrane, CINAHL, PubMed, Springer, Google Scholar, and the Web of Science databases.

RESULTS

The 1,949 articles were accessed in the total, and 20 articles have been included in the review. In the studies being evaluated, it can be determined that HPN has influenced the quality of life, performance status, and the nutrition level of cancer patients positively. Most frequently seen complications were infections relating to the catheter, the mechanical obstruction in the catheter and venous thrombosis. For each 1,000 days with HPN or a catheter, infections in the interval of 0.05 and 3.08, mechanical problems in the interval of 0.07 and 2.13, and thrombosis in the interval of 0.05 and 0.20 were determined.

CONCLUSIONS

While HPN influenced quality of life, nutrition, and the personal performance of cancer patients positively, the rate of complications is at a level that can be managed at home.

Incidence, causes and risk factors for 30-day readmission after radical gastrectomy for gastric cancer: a retrospective study of 2,023 patients

The aim of this retrospective study was to investigate the incidence of, causes and risk factors for readmission to hospital ≤30 days after discharge of patients who underwent radical gastrectomy for gastric cancer. A total of 2,023 patients underwent radical gastrectomy operations from November 2010 to July 2017 in our hospital. Of these, 60 patients (3.0%) were readmitted within 30 days after their original discharge. The median time span between the index discharge and readmission was 14 days and the median time for readmission was 8 days. The main reasons for readmission were intestinal obstruction (n = 10, 16.7%), intra-abdominal fluid collection (n = 9, 15.0%), abdominal pain (n = 7, 11.7%), nutritional difficulty (n = 4, 6.7%) and anastomotic leakage (n = 4, 6.7%). Five patients (8.3%) required intensive care and 4 patients (6.7%) died from sudden cardiac arrest, gastrointestinal bleeding, sepsis or multiple organ dysfunctions. Multivariate analysis revealed that post-operative complications (Odds Ratio = 5.116, 95% confidence interval: 2.885–9.073, P < 0.001) was the only independent risk factor for readmission. Thus, appropriate strategies on discharge and close follow-ups for these high-risk patients should be drawn up in order to enhance significantly their quality of care.

Predictors of 30-day readmissions after gastrectomy for malignancy

BACKGROUND

The objective of this study is to identify risk factors associated with readmission after gastrectomy to potentially identify potential areas for targeted improvements. Hospital readmission after surgery is a topic of interest in health-care policy among hospitals, payers, and providers. Readmissions are associated with increased costs, morbidity, and mortality. Readmission rates have been proposed as a quality metric for hospitals and quality indicator of individual surgeon's performance. In addition, the Centers for Medicare and Medicaid Services has reduced payments to hospitals with excessive readmissions for certain diagnoses.

MATERIALS AND METHODS

All gastrectomy procedures for malignancy in patients aged ≥18 y from 2005 to 2011 were queried from the California State Inpatient Database. Patients who died during index admission were excluded. Descriptive statistics were examined between all baseline variables and readmission status. Logistic regression models were adjusted for age, race, sex, and insurance status.

RESULTS

A total of 6985 patients underwent gastrectomy for malignancy; 16.5% of the patients were readmitted after postoperative discharge. Readmission rate did not change significantly over time. Multivariable analysis demonstrated that the occurrence of any postoperative complications, postoperative length of stay greater than 10 d, discharge to skilled nursing facility or home health care, combined resection with distal pancreatectomy and/or splenectomy, and patient comorbidities like diabetes mellitus and renal failure were independently associated with readmissions.

CONCLUSIONS

The findings suggest that focusing on quality improvement efforts by targeting reduction of postoperative complications may reduce readmission rates.

Morbidity and Mortality After Gastrectomy: Identification of Modifiable Risk Factors

BACKGROUND

Morbidity after gastrectomy remains high. The potentially modifiable risk factors have not been well described. This study considers a series of potentially modifiable patient-specific and perioperative characteristics that could be considered to reduce morbidity and mortality after gastrectomy.

METHODS

This retrospective cohort study includes adults in the ACS NSQIP PUF dataset who underwent gastrectomy between 2011 and 2013. Sequential multivariable models were used to estimate effects of clinical covariates on study outcomes including morbidity, mortality, readmission, and reoperation.

RESULTS

Three thousand six hundred and seventy-eight patients underwent gastrectomy. A majority of patients had distal gastrectomy (N = 2,799, 76.1 %) and had resection for malignancy (N = 2,316, 63.0 %). Seven hundred and ninety-eight patients (21.7 %) experienced a major complication. Reoperation was required in 290 patients (7.9 %). Thirty-day mortality was 5.2 %. Age (OR = 1.01, 95 % CI = 1.01-1.02, p = 0.001), preoperative malnutrition (OR = 1.65, 95 % CI = 1.35-2.02, p < 0.001), total gastrectomy (OR = 1.63, 95 % CI = 1.31-2.03, p < 0.001), benign indication for resection (OR = 1.60, 95 % CI = 1.29-1.97, p < 0.001), blood transfusion (OR = 2.57, 95 % CI = 2.10-3.13, p < 0.001), and intraoperative placement of a feeding tubes (OR = 1.28, 95 % CI = 1.00-1.62, p = 0.047) were independently associated with increased risk of morbidity. Association between tobacco use and morbidity was statistically marginal (OR = 1.23, 95 % CI = 0.99-1.53, p = 0.064). All-cause postoperative morbidity had significant associations with reoperation, readmission, and mortality (all p < 0.001).

CONCLUSIONS

Mitigation of perioperative risk factors including smoking and malnutrition as well as identified operative considerations may improve outcomes after gastrectomy. Postoperative morbidity has the strongest association with other measures of poor outcome: reoperation, readmission, and mortality.

Readmission Following Gastric Cancer Resection: Risk Factors and Survival

BACKGROUND

This study utilized a multi-institutional database to evaluate risk factors for readmission in patients undergoing curative gastrectomy for gastric adenocarcinoma with the intent of describing both perioperative risk factors and the relationship of readmission to survival.

METHODS

Patients who underwent curative resection of gastric adenocarcinoma from 2000 to 2012 from seven academic institutions of the US Gastric Cancer Collaborative were analyzed. In-hospital deaths and palliative surgeries were excluded, and readmission was defined as within 30 days of discharge. Univariate and multivariable logistic regression analyses were employed and survival analysis conducted.

RESULTS

Of the 855 patients, 121 patients (14.2 %) were readmitted. Univariate analysis identified advanced age (p < 0.0128), American Society of Anesthesiology status ≥3 (p = 0.0045), preexisting cardiac disease (p < 0.0001), hypertension (p = 0.0142), history of smoking (p = 0.0254), increased preoperative blood urea nitrogen (BUN; p = 0.0426), concomitant pancreatectomy (p = 0.0056), increased operation time (p = 0.0384), estimated blood loss (p = 0.0196), 25th percentile length of stay (<7 days, p = 0.0166), 75th percentile length of stay (>12 days, p = 0.0256), postoperative complication (p < 0.0001), and total gastrectomy (p = 0.0167) as risk factors for readmission. Multivariable analysis identified cardiac disease (odds ratio (OR) 2.4, 95 % confidence interval (CI) 1.6-3.3, p < 0.0001), postoperative complication (OR 2.3, 95 % CI 1.6-5.4, p < 0.0001), and pancreatectomy (OR 2.2, 95 % CI 1.1-4.1, p = 0.0202) as independent risk factors for readmission. There was an association of decreased overall median survival in readmitted patients (39 months for readmitted vs. 103 months for non-readmitted). This was due to decreased survival in readmitted stage 1 (p = 0.0039), while there was no difference in survival for other stages. Stage I readmitted patients had a higher incidence of cardiac disease than stage I non-readmitted patients (58 vs. 24 %, respectively, p = 0.0002).

CONCLUSIONS

Within this multi-institutional study investigating readmission in patients undergoing curative resection for gastric cancer, cardiac disease, postoperative complication, and concomitant pancreatectomy were identified as significant risk factors for readmission. Readmission was associated with decreased overall median survival, but on further analysis, this was driven by differences in survival for stage I disease only.
