Nationwide Trends in Acute and Chronic Pancreatitis Among Privately Insured Children and Non-Elderly Adults in the United States, 2007-2014.

BACKGROUND & AIMS: Epidemiologic analyses of acute pancreatitis (AP) and chronic pancreatitis (CP) provide insight into causes and strategies for prevention and affect allocation of resources to its study and treatment. We sought to determine current and accurate incidences of AP and CP, along with the prevalence of CP, in children and adults in the United States. METHODS: We collected data from the Truven MarketScan Research Databases of commercial inpatient and outpatient insurance claims in the United States from 2007 through 2014 (patients 0-64 years old). We calculated the incidences of AP and CP and prevalence of CP based on International Classification of Diseases, 9th Revision diagnosis codes. Children were defined as 18 years or younger and adults as 19 to 64 years old. RESULTS: The incidence of pediatric AP was stable from 2007 through 2014, remaining at 12.3/100,000 persons in 2014. Meanwhile, the incidence for adult AP decreased from 123.7/100,000 persons in 2007 to 111.2/100,000 persons in 2014. The incidence of CP decreased over time in children (2.2/100,000 persons in 2007 to 1.9/100,000 persons in 2014) and adults (31.7/100,000 persons in 2007 to 24.7/100,000 persons in 2014). The prevalences of pediatric and adult CP were 5.8/100,000 persons and 91.9/100,000 persons, respectively, in 2014. Incidences of AP and CP increased with age. We found little change in incidence during the first decade of life but linear increases starting in the second decade. CONCLUSIONS: We performed a comprehensive epidemiologic analysis of privately insured, non-elderly adults and children with AP and CP in the United States. Changes in gallstone formation, smoking, and alcohol consumption, along with advances in pancreatitis management, may be responsible for the stabilization and even decrease in the incidences of AP and CP.

Incidence, Admission Rates, and Economic Burden of Adult Emergency Visits for Chronic Pancreatitis: Data From the National Emergency Department Sample, 2006 to 2012.

INTRODUCTION: Chronic pancreatitis (CP) is a common reason for emergency department (ED) visits, but little research has examined ED use by patients with CP. MATERIALS AND METHODS: The Nationwide Emergency Department Sample (2006 to 2012) was interrogated to evaluate trends in adult ED visits for a primary diagnosis of CP (International Classification of Disease, 9th revision, Clinical Modification code: 577.1), the rates of subsequent hospital admission, and total charges. A survey logistic regression model was used to determine factors associated with hospitalization from the ED. RESULTS: We identified 253,753 ED visits with a primary diagnosis of CP. No significant trends in annual incidence were noted. However, the ED-to-hospitalization rates decreased by 3% per year (P<0.001) and mean ED charges after adjusting for inflation increased by 11.8% per year (P<0.001). Higher Charlson comorbidity index, current smoker status, alcohol use, and biliary-related CP were associated with hospitalization. In hospitalized patients, length of stay decreased by 2.2% per year (P=0.003) and inpatient charges increased by 2.9% per year (P=0.004). CONCLUSIONS: Patient characteristics associated with higher risk of hospitalization from the ED deserve further attention.

Surgical management of chronic pancreatitis: current utilization in the United States.

BACKGROUND: Surgical intervention is uncommon in chronic pancreatitis. Literature largely describes single institution or international experiences. This study describes US-based chronic pancreatitis surgical management. METHODS: Retrospective analysis of chronic pancreatitis patients in the Healthcare Cost and Utilization Project Florida State Inpatient Database 2007-2011. Patients with malignancy or congenital abnormalities were excluded. Univariate analysis using the chi-square test. The number of readmissions, inpatient length of stay and cost using Wilcoxon's signed-rank test. Multivariate analysis of surgery by logistic regression. RESULTS: Twenty-one thousand four hundred and forty-five patients with chronic pancreatitis. 10.8% (2 307) underwent surgery including 1652 cholecystectomies, 564 drainage procedures and 498 pancreatectomies. Procedures decreased from 12.1% to 8.3% over time (P < 0.001), but intervention within 3 months increased (7.2% to 8.4%; P = 0.017). 15.3% (3 278) had pancreatic cysts/pseudocysts and 43.4% (9 312) had diabetes. The median numbers of admissions were 2 [interquartile range (IQR) 1,5] and 3 (IQR 2,7) among non-surgical and surgical patients, respectively (P < 0.001). Predictors of surgery were fewer co-morbidities, private insurance, and either diabetes mellitus or pancreatic cyst/pseudocyst. CONCLUSION: Chronic pancreatitis leads to numerous inpatient readmissions, but surgical intervention only occurs in a minority of cases. Complicated patients are more likely to undergo surgery. The complexities of chronic pancreatitis management warrant early multidisciplinary evaluation and ongoing consideration of surgical and non-surgical options.

Pancreatic enzyme replacement therapy and resource utilization in patients with chronic pancreatitis in a US healthcare system: a retrospective study.

OBJECTIVE: To assess the association between pancreatic enzyme replacement therapy (PERT) and resource utilization among patients with chronic pancreatitis (CP) in a large Midwestern US healthcare system. METHODS: This retrospective cohort study used electronic medical record data. Eligible patients (N = 2445) were aged ≥18 years and diagnosed with non-cystic fibrosis CP between January 2005 and December 2018, with ≥6 months' follow-up; study initiation was first encounter with the healthcare system. Patients in the PERT group were prescribed PERT at ≥1 encounter; patients in the non-PERT group were not prescribed PERT at any encounter. RESULTS: In total, 62,899 encounters were reviewed (PERT, n = 22,935; non-PERT, n = 39,964). More patients in the PERT group were younger, male, White, married/partnered and with private insurance than those in the non-PERT group. They also received longer care and had more overall encounters, fewer outpatient and day surgery/24-hour observation encounters, and more inpatient encounters. Emergency room encounters were similar between groups. Average cost by encounter was similar between groups ($225 and $213, respectively). CONCLUSIONS: Despite similar average costs per encounter, the groups had very different encounter types. More inferential research on PERT use among patients with CP is needed, particularly regarding resource utilization and long-term outcomes.

Long-term outcomes of endoscopic vs surgical drainage of the pancreatic duct in patients with chronic pancreatitis.

BACKGROUND & AIMS: A randomized trial that compared endoscopic and surgical drainage of the pancreatic duct in patients with advanced chronic pancreatitis reported a significant benefit of surgery after a 2-year follow-up period. We evaluated the long-term outcome of these patients after 5 years. METHODS: Between 2000 and 2004, 39 symptomatic patients were randomly assigned to groups that underwent endoscopic drainage or operative pancreaticojejunostomy. In 2009, information was collected regarding pain, quality of life, morbidity, mortality, length of hospital stay, number of procedures undergone, changes in pancreatic function, and costs. Analysis was performed according to an intention-to-treat principle. RESULTS: During the 79-month follow-up period, one patient was lost and 7 died from unrelated causes. Of the patients treated by endoscopy, 68% required additional drainage compared with 5% in the surgery group (P = .001). Hospital stay and costs were comparable, but overall, patients assigned to endoscopy underwent more procedures (median, 12 vs 4; P = .001). Moreover, 47% of the patients in the endoscopy group eventually underwent surgery. Although the mean difference in Izbicki pain scores was no longer significant (39 vs 22; P = .12), surgery was still superior in terms of pain relief (80% vs 38%; P = .042). Levels of quality of life and pancreatic function were comparable. CONCLUSIONS: In the long term, symptomatic patients with advanced chronic pancreatitis who underwent surgery as the initial treatment for pancreatic duct obstruction had more relief from pain, with fewer procedures, than patients who were treated endoscopically. Importantly, almost half of the patients who were treated with endoscopy eventually underwent surgery.

Direct costs for nonsurgical management of Chronic Pancreatitis in a tertiary care teaching hospital.

BACKGROUND: Chronic pancreatitis (CP) is a leading cause of hospitalization among gastrointestinal diseases resulting in considerable financial burden to patients. However the direct costs for nonsurgical management in CP remains unexplored. METHODS: A cross sectional study was carried out (2011-14) in the Department of Gastroenterology, Kasturba Hospital, Manipal, India. Demographic and clinical data on laboratory investigations, interventions and follow up were obtained from the medical records department. Item costs were derived from the hospital electronic billing section. Cost was expressed as median annual cost per patient. RESULTS: 65 (male 48; 73.8%) patients were included. Their median age was 31 (range 12-68) years. The annual median (IQR) total cost per patient was INR 88,892 (70,550.5-116,004); [USD 1410(1119-1841); € 1155(916-1507)], comprising of INR 61,089 (39,102.5-90,360.5) [USD 970 (621-1434); € 793(508-1174)] for outpatient management and INR 32,450 (11,016-46,958) [USD 515 (175-745); €421(143-610)] for hospitalization. 69.5% of the treatment cost was attributed to outpatient treatment. Drugs contributed to 54%, hospitalization incurred 30.5%, investigations 12% and professional fees (3.5%) of the total cost. Pancreatic enzyme replacement therapy (PERT) cost contributed to three-quarters of drug therapy. Use of rabeprazole as against pantoprazole reduced the overall annual cost of therapy by 4%. CONCLUSIONS: This study depicts the first nonsurgical management of accrued direct costs associated with CP due to expensive medications. Due to the high cost for PERT, its usefulness needs proper validation by cost benefit analysis.

Financial Burden Secondary to Delay in Cholecystectomy Following Mild Biliary Pancreatitis.

AIM OF THE STUDY: The guidelines recommend that patients with mild gallstones pancreatitis should undergo a definitive management for gallstones during the same admission or within the next two weeks. The aim of this study was to estimate the financial cost resulting from a delay in surgical management following mild gallstones pancreatitis. This includes the costs of readmissions with biliary events and the subsequent investigations required during these admissions. MATERIALS AND METHODS: A retrospective analysis included patients with gallstone pancreatitis who were admitted to a district general hospital in the United Kingdom over one year. Patients with severe pancreatitis and those unfit for surgery were excluded. RESULTS: Forty patients were included in the study, 27 females (67%) and 13 males (33%). Mean age was 50.2 years. Twenty-two patients of the total presented with a single admission with gallstone pancreatitis prior to an elective surgery; however, 18 patients (45%) required recurrent admissions. The duration between the first admission and surgery ranged from 14 to 389 days (median of 99 days). Only one patient (2.5%) had cholecystectomy within two weeks of admission as per guidelines. Twenty-two ultrasound scans, four computed tomography scans, 15 magnetic resonance cholangiopancreatography, and two endoscopic retrograde cholangiopancreatography were the total of the extra-investigations required during readmissions. Estimated costs of extra admissions and extra investigations exceeded £33,000. CONCLUSIONS: The delay in cholecystectomy for patients admitted with mild gallstone pancreatitis and fit for surgery has resulted in high readmission rate with biliary events, and subsequently high extrax costs.

Robotic longitudinal pancreaticojejunostomy for chronic pancreatitis: Comparison of clinical outcomes and cost to the open approach.

BACKGROUND: This study compares clinical and cost outcomes of robot-assisted laparoscopic (RAL) and open longitudinal pancreaticojejunostomy (LPJ) for chronic pancreatitis. METHODS: Clinical and cost data were retrospectively compared between open and RAL LPJ performed at a single center from 2008-2015. RESULTS: Twenty-six patients underwent LPJ: 19 open and 7 RAL. Two robot-assisted cases converted to open were included in the open group for analysis. Patients undergoing RAL LPJ had less intraoperative blood loss, a shorter surgical length of stay, and lower medication costs. Operation supply cost was higher in the RAL group. No difference in hospitalization cost was found. CONCLUSIONS: Versus the open approach, RAL LPJ performed for chronic pancreatitis shortens hospitalization and reduces medication costs; hospitalization costs are equivalent. A higher operative cost for RAL LPJ is mitigated by a shorter hospitalization. Decreased morbidity and healthcare resource economy support use of the robotic approach for LPJ when appropriate.

Cost-effectiveness of total pancreatectomy and islet cell autotransplantation for the treatment of minimal change chronic pancreatitis.

INTRODUCTION: The current standard of care for the management of minimal change chronic pancreatitis (MCCP) is medical management. Controversy exists, however, regarding the use of surgical intervention for MCCP. We hypothesized that total pancreatectomy and islet cell autotransplantation (TPIAT) decreases long-term resource utilization and improves quality of life, justifying initial costs and risks. METHODS: Detailed perioperative outcomes from 46 patients with MCCP populated a Markov model comparing medical management to TPIAT. Mortality, complications, readmission rates, insulin and narcotic use, imaging, and endoscopy were included in the model. Outcomes reported were survival, measured in quality-adjusted life years (QALYs), and costs, in 2013 US dollars. RESULTS: In medical patients, annual mean hospital admissions were 1.6 (range = 0-11), endoscopy 1.4 (0-6), and imaging (CT/MRI) 1.5 (0-4). In surgical patients, there were no perioperative deaths, with complication and 30-day readmission rates of 47 and 37%. One year after TPIAT, annual mean admissions, endoscopy, and imaging had decreased to 0.9 (0-4), 0.4 (0-2), and 0.9 (0-5); monthly narcotic use decreased from 138 to 37 morphine equivalents (p = 0.012). Cost and survival for TPIAT versus medical management were $153,575/14.9 QALYs and $196,042/11.5 QALYs, respectively. CONCLUSIONS: In patients with MCCP, TPIAT is associated with decreased cost and increased quality-adjusted survival. Providers and insurers should more enthusiastically embrace TPIAT use as a more effective cost-saving strategy.

The socio-economic impact of chronic pancreatitis: a systematic review.

RATIONALE, AIMS AND OBJECTIVES: Chronic pancreatitis (CP) is a progressive inflammatory disorder with pain being the most frequent symptom. It is associated with loss of function, pancreatogenic diabetes and digestive enzyme deficiency. The impact of local complications and loss of pancreatic function results in unknown and unreported costs. This study attempts to identify both the direct and indirect costs associated with CP. METHODS: A MEDLINE literature review was performed for all relevant articles relating to any aspect of direct and indirect costs as a result of CP. RESULTS: In the UK, there are 12,000 admissions per annum of patients with CP at an estimated cost of £55.8 million. The costs for loss of pancreatic function are estimated at £45-90 million and $75.1 million for endocrine and exocrine function, respectively. Chronic pain contributes $638 million per year in costs. The protracted course of CP and paucity of monetary data make quantifying direct and indirect costs difficult. An estimate of direct and indirect costs is at £285.3 million per year. This equates to £79,000 per person per year. CONCLUSIONS: Patients with CP consume a disproportionately high volume of resources.

The economics of pancreas surgery.

Pancreas surgery is a paradigm for high-acuity surgical specialization. Given the current intrigue over containing health care expenditures, pancreas surgery provides an ideal model to investigate the cost of care. This article explores the economics of this field from literature accrued over the last 2 decades. The cost of performing a pancreatic resection is established and then embellished with a discussion of the effects of clinical care paths. Then the influence of complications on costs is explored. Next, cost is investigated as an emerging outcome metric regarding variations in pancreatic surgical care. Finally, the societal-level fiscal impact is considered.

Patient satisfaction and cost-effectiveness following total pancreatectomy with islet cell transplantation for chronic pancreatitis.

OBJECTIVES: Chronic pancreatitis (CP) results in an extremely poor quality of life and substantially increases health care utilization. Few data exist regarding the cost-effectiveness of surgical treatment for CP. METHODS: This article examined the cost-effectiveness of total pancreatectomy (TP) with islet cell autotransplantation (IAT) for CP. RESULTS: Sixty patients undergoing TP + IAT and 37 patients undergoing TP were identified. Surgery resulted in significant reduction in opiate use, frequency of hospital admissions, and length of stay as well as visual analog scale scores for pain. Total pancreatectomy + IAT resulted in longer survival than TP alone (16.6 vs 12.9 years); 21.6% of patients with TP + IAT were insulin-independent, and those requiring insulin have reduced daily requirements compared with those having TP alone (22 vs 35 IU). The cost of TP + IAT with attendant admission and analgesia costs over the 16-year survival period was £110,445 compared with £101,608 estimated 16-year costs if no TP + IAT was undertaken. CONCLUSIONS: Total pancreatectomy + IAT is effective in improving pain and reducing analgesia. Islet cell transplantation offers the chance of insulin independence and results in lower insulin requirements, as well as conferring a survival advantage when compared with TP alone. Total pancreatectomy + IAT is cost-neutral when compared with nonsurgical or segmental surgical therapy.

Long-period pancreatic stenting for painful chronic calcified pancreatitis required higher medical costs and frequent hospitalizations compared with surgery.

OBJECTIVES: The aim of this study was to compare the benefits between endoscopic drainage and surgical drainage of the pancreatic duct for patients with chronic calcified pancreatitis. METHODS: A total of 68 patients were classified into endoscopic (n = 34) or surgical (n = 34) treatment groups. Patients receiving endoscopic treatment were further divided into 2 subgroups: a short-period group, patients who could discontinue serial pancreatic stenting within 1 year (n = 19); and a long-period group, patients who needed pancreatic drainage by serial endoscopic stenting for more than 1 year (n = 15). The medical records of these patients were retrospectively analyzed. RESULTS: Hospital stays, frequency of hospitalizations, and medical expense were similar between the short-period endoscopic treatment group and surgery group. On the other hand, patients in the long-period endoscopic treatment group required significantly longer hospital stays, more frequent hospitalizations, and had higher medical expenses than the short-period endoscopic treatment group as well as than the surgery group. CONCLUSIONS: Patients who underwent serial endoscopic stenting for more than 1 year showed no benefit compared with surgical treatment in terms of the frequency of hospital stays and medical costs.

[Insurance costs in pancreatic surgery : does the pecuniary aspect indicate formation of centers?]. / Kostenträgerrechnung in der pankreaschirurgie : spricht die pekuniäre betrachtung für eine zentrenbildung?

BACKGROUND: Pancreatic resections in specialized centers are associated with low mortality, however, still with high morbidity. The complication rate can be reduced by long-term experience in high volume centers. In this study the influence of complications on costs in the German DRG system were analyzed. PATIENTS AND METHODS: Data regarding operation time, hospital stay, complications and costs of 36 patients undergoing pancreatic head resection in the years 2005 and 2006 were collected and analyzed retrospectively. Statistical analysis was performed using the Mann-Whitney U-test. A p-value of p<0.05 was considered statistically significant. RESULTS: Postoperative complications caused an increase in the duration of hospital stay from a median of 16 (range 11-38) to 33 (10-69) days. Costs, especially for ICU treatment and radiographic diagnostics, rose significantly. The average overall costs were 10,015 EUR (range 8,099-14,785 EUR) in patients without complications (n = 21) and 15,340 EUR (9,368-31,418 EUR) in patients with complications (n = 15). In contrast, according to the German DRG system 13,835 EUR (10,441-15,062 EUR) and 15,062 EUR (10,441-33,217 EUR) were refunded on average, respectively. CONCLUSIONS: This case-cost calculation proves that pancreatic surgery in the context of the German DRG system can only be performed economically neutral in centers with low complications rates. The concentration of pancreatic surgery to centers with low complications rates, namely high volume centers, must be recommended from an economic point of view.

The epidemiology and socioeconomic impact of chronic pancreatitis.

Epidemiological studies have been published worldwide in recent decades describing the incidence, mortality, aetiology and trends of chronic pancreatitis. Accumulated evidence suggests that chronic pancreatitis is increasing in incidence and hospital admission rates are rising accordingly. Alcoholic chronic pancreatitis was previously more common in the developed world than elsewhere, but is now increasing worldwide due to growing per capita alcohol consumption in each nation. Supporting alcohol and smoking cessation in individual patients is essential to slow disease progression and improve overall health, as most patients will die of cirrhosis, cardiovascular disease or smoking related cancers rather than chronic pancreatitis. The socioeconomic impact of chronic pancreatitis is difficult to quantify as little data exists, however given the rising incidence the costs to health care and society are likely to increase. This chapter will describe the epidemiology and aetiology of chronic pancreatitis worldwide and discusses the factors that influence its socioeconomic impact.

Treatment for painful calcified chronic pancreatitis: extracorporeal shock wave lithotripsy versus endoscopic treatment: a randomised controlled trial.

BACKGROUND: In chronic pancreatitis, obstruction of the main pancreatic duct (MPD) may contribute to the pathogenesis of pain. Pilot studies suggest that extracorporeal shock wave lithotripsy (ESWL) alone relieves pain in calcified chronic pancreatitis. AIM: To compare ESWL alone with ESWL and endoscopic drainage of the MPD for treatment of pain in chronic pancreatitis. SUBJECTS: Patients with uncomplicated painful chronic pancreatitis and calcifications obstructing the MPD. METHODS: 55 patients were randomised to ESWL alone (n = 26) or ESWL combined with endoscopy (n = 29). RESULTS: 2 years after trial intervention, 10 (38%) and 13 (45%) patients of the ESWL alone and ESWL combined with endoscopy group, respectively, had presented pain relapse (primary outcome) (OR 0.77; 95% CI 0.23 to 2.57). In both groups, a similar decrease was seen after treatment in the MPD diameter (mean decrease 1.7 mm; 95% CI 0.9 to 2.6; p<0.001), and in the number of pain episodes/year (mean decrease, 3.7; 95% CI 2.6 to 4.9; p<0.001). Treatment costs per patient were three times higher in the ESWL combined with endoscopy group compared with the ESWL alone group (p = 0.001). The median delay between the onset of chronic pancreatitis and persistent pain relief for both groups was 1.1 year (95% CI 0.7 to 1.6), as compared with 4 years (95% CI 3 to 4) for the natural history of chronic pancreatitis in a reference cohort (p<0.001). CONCLUSIONS: ESWL is a safe and effective preferred treatment for selected patients with painful calcified chronic pancreatitis. Combining systematic endoscopy with ESWL adds to the cost of patient care, without improving the outcome of pancreatic pain.
