Utilization trends for endoscopic ablation therapy and esophagectomy in Barrett's esophagus from 2005 to 2019.

Guidelines have shifted to now recommend endoscopic eradication therapy for Barrett's esophagus (BE) with low and high-grade dysplasia. Previously, esophagectomy was the standard therapy for high-grade dysplasia. However, it is unclear to what degree ablation therapy has affected utilization of esophagectomy. In this retrospective observational cohort study of BE patients without cancer from the Premier Healthcare Database, the prevalence of utilization of endoscopic ablation therapy and of esophagectomy in BE were calculated and temporal trends were evaluated. A total of 938, 333 BE cases were included in the study. There was a significantly increasing trend of ablation over the period 2006 to 2010 (Annual Percentage Change (APC); 95% CI 0.56% [0.51%, 0.61%]), a significantly decreasing trend for the period 2011 to 2015 (APC; 95% CI - 0.15% [- 0.20%, - 0.11%]), and a shallow increasing trend for the period 2016 to 2019 (APC; 95% CI 0.09% [0.06%, 0.11%]). For esophagectomy, there was a significantly decreasing trend for the period 2006 to 2009 (APC; 95% CI - 0.03% [- 0.04%, - 0.02%]; P < 0.001) that corresponded to the uptrend in utilization of endoscopic ablation. There was a stable trend of esophagectomy over the period 2010 to 2019 (APC; 95% CI - 0.0006% [- 0.0002%, 0.0005%]; P = 0.1947). Adoption and increased utilization of endoscopic ablation therapy for BE has coincided with a decrease in esophagectomy, and is the predominate method of therapy for BE with dysplasia.

The Trends in Adoption, Outcomes, and Costs of Laparoscopic Surgery for Colorectal Cancer in the Elderly Population.

BACKGROUND: The elderly constitute the majority of both colorectal cancer and surgical volume. Despite established safety and feasibility, laparoscopy may remain underutilized for colorectal cancer resections in the elderly. With proven benefits, increasing laparoscopy in elderly colorectal cancer patients could substantially improve outcomes. Our goal was to evaluate utilization and outcomes for laparoscopic colorectal cancer surgery in the elderly. METHODS: A national inpatient database was reviewed for elective inpatient resections for colorectal cancer from 2010 to 2015. Patients were stratified into elderly (≥ 65 years) and non-elderly cohorts (< 65 years), then grouped into open or laparoscopic procedures. The main outcomes were trends in utilization by approach and total costs, length of stay (LOS), readmission, and complications by approach in the elderly. Multivariable regression models were used to control for differences across platforms, adjusting for patient demographics, comorbidities, and hospital characteristics. RESULTS: Laparoscopic adoption for colorectal cancer in the elderly increased gradually until 2013, then declined, with simultaneously increasing rates of open surgery. Laparoscopy significantly improved all primary outcomes compared to open surgery (all p < 0.01). From the adjusted analysis, laparoscopy reduced complications by 30%, length of stay by 1.99 days, and total costs by $3276/admission. Laparoscopic patients were 34% less likely to be readmitted; when readmitted, the episodes were less expensive when index procedure was laparoscopic. CONCLUSION: The adoption of laparoscopy for colorectal cancer surgery in the elderly is slow and even declining recently. In addition to the clinical benefits, there are reduced overall costs, creating a tremendous value proposition if use can be expanded. PRECIS: This national contemporary study shows the slow uptake and recent decline in adaption of laparoscopic surgery for colorectal cancer in the elderly, despite the benefits in clinical outcomes and costs found. This data can be used to target education, regionalization, and quality improvement efforts in this expanding population.

Risk factors for cardiopulmonary and respiratory arrest in medical and surgical hospital patients on opioid analgesics and sedatives.

BACKGROUND: Opioid induced respiratory depression is a known cause of preventable death in hospitals. Medications with sedative properties additionally potentiate opioid-induced respiratory and sedative effects, thereby elevating the risk for adverse events. The goal of this study was to determine what specific factors increase the risk of in-hospital cardiopulmonary and respiratory arrest (CPRA) in medical and surgical patients on opioid and sedative therapy. METHODS: The present study analyzed 14,504,809 medical inpatient and 6,771,882 surgical inpatient discharges reported into the Premier database from 2008 to 2012. Patients were divided in four categories: on opioids; on sedatives; on both opioids and sedatives; and on neither opioids nor sedatives. RESULTS: During hospital admission, 57% of all medical patients and 90% of all surgical patients were prescribed opioids, sedatives, or both. Surgical patients had a higher incidence of CPRA than medical patients (6.17 vs. 3.77 events per 1000 admissions; Relative Risk: 1.64 [95%CI: 1.62-1.66; p<0.0001). Opioids and sedatives were found to be independent predictors of CPRA (adjusted OR of 2.24 [95%CI: 2.18-2.29] for opioids and adjusted OR 1.80 [95%CI: 1.75-1.85] for sedatives in medical patients, and adjusted OR of 1.12 [95%CI: 1.07-1.16] for opioids and adjusted OR of 1.58 [95%CI: 1.51-1.66] for sedatives in surgical patients), with the highest risk in groups who received both types of medications (adjusted OR of 3.83 [95% CI: 3.74-3.92] in medical patients, and adjusted OR of 2.34 [95% CI: 2.25-2.42] in surgical patients) compared with groups that received neither type of medication. The common risk factors of CPRA in medical and surgical patients receiving both opioids and sedatives were Hispanic origin, mild liver disease, obesity, and COPD. Additionally, medical and surgical groups had their own unique risk factors for CPRA when placed on opioid and sedative therapy. CONCLUSIONS: Opioids and sedatives are independent and additive predictors of CPRA in both medical and surgical patients. Receiving both classes of medications further exacerbates the risk of CPRA for these patients. By identifying groups at risk among medical and surgical in-hospital patients, this study provides a step towards improving our understanding of how to use opioid and sedative medications safely, which may influence our treatment strategies and outcomes. More precise monitoring of selected high-risk patients may help prevent catastrophic cardiorespiratory complications from these medications. As a retrospective administrative database analysis, this study does not establish the causality or the temporality of the events but rather draws statistically significant associations between the clinical factors and outcomes.

Predicting opportunities to increase utilization of laparoscopy for rectal cancer.

BACKGROUND: Despite proven safety and efficacy, rates of laparoscopy for rectal cancer in the US are low. With reports of inferiority with laparoscopy compared to open surgery, and movements to develop accredited centers, investigating utilization and predictors of laparoscopy are warranted. Our goal was to evaluate current utilization and identify factors impacting use of laparoscopic surgery for rectal cancer. METHODS: The Premier™ Hospital Database was reviewed for elective inpatient rectal cancer resections (1/1/2010-6/30/2015). Patients were identified by ICD-9-CM diagnosis codes, and then stratified into open or laparoscopic approaches by ICD-9-CM procedure codes or billing charge. Logistic multivariable regression identified variables predictive of laparoscopy. The Cochran-Armitage test assessed trend analysis. The main outcome measures were trends in utilization and factors independently associated with use of laparoscopy. RESULTS: 3336 patients were included-43.8% laparoscopic (n = 1464) and 56.2% open (n = 1872). Use of laparoscopy increased from 37.6 to 55.3% during the study period (p < 0.0001). General surgeons performed the majority of all resections, but colorectal surgeons were more likely to approach rectal cancer laparoscopically (41.31 vs. 36.65%, OR 1.082, 95% CI [0.92, 1.27], p < 0.3363). Higher volume surgeons were more likely to use laparoscopy than low-volume surgeons (OR 3.72, 95% CI [2.64, 5.25], p < 0.0001). Younger patients (OR 1.49, 95% CI [1.03, 2.17], p = 0.036) with minor (OR 2.13, 95% CI [1.45, 3.12], p < 0.0001) or moderate illness severity (OR 1.582, 95% CI [1.08, 2.31], p < 0.0174) were more likely to receive a laparoscopic resection. Teaching hospitals (OR 0.842, 95% CI [0.710, 0.997], p = 0.0463) and hospitals in the Midwest (OR 0.69, 95% CI [0.54, 0.89], p = 0.0044) were less likely to use laparoscopy. Insurance status and hospital size did not impact use. CONCLUSIONS: Laparoscopy for rectal cancer steadily increased over the years examined. Patient, provider, and regional variables exist, with hospital status, geographic location, and colorectal specialization impacting the likelihood. However, surgeon volume had the greatest influence. These results emphasize training and surgeon-specific outcomes to increase utilization and quality in appropriate cases.

Capnography sensor use is associated with reduction of adverse outcomes during gastrointestinal endoscopic procedures with sedation administration.

BACKGROUND: Evidence to date suggests that capnography monitoring during gastrointestinal endoscopic procedures (GEP) reduces the incidence of hypoxemia, but the association of capnography monitoring with the incidence of other adverse outcomes surrounding these procedures has not been well studied. Our aims were to estimate the incidence of pharmacological rescue events and death at discharge from an inpatient or outpatient hospitalization where GEP was performed with sedation, and to determine if capnography monitoring was associated with reduced incidence of these adverse outcomes. METHODS: This retrospective Premier Database analysis included medical inpatients and all outpatients undergoing GEP with sedation. Patients were grouped as follows: (1) pulse oximetry (SpO2) only, (2) capnography only, (3) SpO2 with capnography, and (4) neither SpO2 nor capnography. Multivariable logistic regression and propensity-score matching were used to compare patients with capnography sensor use to patients with only SpO2 sensor use. Outcome measures included the incidence of pharmacological rescue events, as defined by administration of naloxone and/or flumazenil, and death. RESULTS: Two hundred fifty eight thousand and two hundred sixty two inpatients and 3,807,151 outpatients were analyzed. For inpatients, capnography monitoring was associated with a 47% estimated reduction in the odds of death at discharge (OR: 0.53 [95% CI: 0.40-0.70]; P < 0.0001) and a non-significant 10% estimated reduction in the odds of pharmacological rescue event at discharge (0.91 [0.65-1.3]; P = 0.5661). For outpatients, capnography monitoring was associated with a 61% estimated reduction in the odds of pharmacological rescue event at discharge (0.39 [0.29, 0.52]; P < 0.0001) and a non-significant 82% estimated reduction in the odds of death at discharge (0.18 [0.02, 1.99]; P = 0.16). CONCLUSIONS: In hospital medical inpatients and all outpatients undergoing GEP performed with sedation, capnography monitoring was associated with a reduced likelihood of pharmacological rescue events in outpatients and death in inpatients when assessed at discharge. Despite the limitations of the retrospective data analysis methodology, the use of capnography during these procedures is recommended.

The Impact of Thoracoscopic Surgery on Payment and Health Care Utilization After Lung Resection.

BACKGROUND: Lung resection by video-assisted thoracoscopic surgery (VATS) is associated with multiple clinical benefits compared with resection by thoracotomy (OPEN). Less is known about reimbursements, costs, and resource use with each approach. This study used a commercial insurance claims database to examine differences between VATS and OPEN lung resections in payment, health care utilization, and estimated days off work for health care visits. METHODS: All adult inpatient discharges for patients undergoing VATS or OPEN lung resection in 2010 were identified from the Truven MarketScan Database (Ann Arbor, MI). RESULTS: A total of 2,611 patients underwent lobectomy (VATS, 270; OPEN, 669) or wedge resection (VATS, 1,332; OPEN, 340). After adjustment, OPEN lobectomies had a longer length of stay (mean difference, 1.79 days) and higher payment to hospitals (mean difference, $3,497) and physicians (mean difference, $433) compared with VATS. Similar findings were noted after wedge resections. OPEN lobectomies had 1.28-times and 1.14-times more health care utilization days within 90 days and 365 days, respectively, after the operation compared with VATS, translating into increased expenditures of $3,260 at 90 days and $822 at 365 days for OPEN procedures. No significant differences in utilization were noted between OPEN and VATS wedge resections, except for fewer outpatient visits within 90 days in the OPEN group. CONCLUSIONS: Compared with an OPEN approach, lobectomy and wedge resection by VATS were associated with lower hospital and physician payments. In addition, lobectomy by VATS was associated with less health care utilization in the early postoperative period and during the first year after the operation. These payment and utilization reductions are important in an era of value-based purchasing in health care.

Low rates of testing and diagnostic codes usage in a commercial clinical laboratory: evidence for lack of physician awareness of chronic kidney disease.

Improving outcomes for chronic kidney disease (CKD) requires early identification and recognition by physicians. There are few data on rates of testing or use of diagnostic codes for CKD. A cross-sectional analysis was performed of patients who were older than 40 yr and had one or more laboratory tests between April 1, 2002, and March 31, 2003, at a Laboratory Corporation of America regional laboratory. Objectives were to determine the frequency of testing for serum creatinine; prevalence of CKD, defined as estimated GFR <60 ml/min per 1.73 m2; and sensitivity of diagnostic codes for CKD for patients with and without risk factors for CKD and with or without cardiovascular disease (CVD). Of the 277,111 patients, 19% had serum creatinine measured, compared with 33 and 71% who had measurements of serum glucose and lipids, respectively. Patients with hypertension, diabetes, and age >60 yr were more likely to be tested for serum creatinine with odds ratio (OR; 95% confidence interval) of 2.09 (2.05 to 2.14), 1.22 (1.19 to 1.25), and 1.24 (1.22 to 1.27) respectively. Among patients tested, 30% had CKD. Sensitivity and specificity of kidney disease diagnostic codes compared with CKD defined by estimated GFR <60 ml/min per 1.73 m2 were 11 and 96%, respectively. In patients with hypertension, diabetes, age >60 years, and CVD, rates of testing and sensitivity of diagnostic codes were 53 and 14%, respectively. Low rates of testing for serum creatinine and insensitivity of diagnostic codes for CKD, even in high-risk patients, suggests inadequate physician awareness of CKD and limited utility of administrative databases for identification of patients with CKD.
