Identifying Conditions With High Prevalence, Cost, and Variation in Cost in US Children's Hospitals.

Importance: Identifying high priority pediatric conditions is important for setting a research agenda in hospital pediatrics that will benefit families, clinicians, and the health care system. However, the last such prioritization study was conducted more than a decade ago and used International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes. Objectives: To identify conditions that should be prioritized for comparative effectiveness research based on prevalence, cost, and variation in cost of hospitalizations using contemporary data at US children's hospitals. Design, Setting, and Participants: This retrospective cohort study of children with hospital encounters used data from the Pediatric Health Information System database. Children younger than 18 years with inpatient hospital encounters at 45 tertiary care US children's hospitals between January 1, 2016, and December 31, 2019, were included. Data were analyzed from March 2020 to April 2021. Main Outcomes and Measures: The condition-specific prevalence and total standardized cost, the corresponding prevalence and cost ranks, and the variation in standardized cost per encounter across hospitals were analyzed. The variation in cost was assessed using the number of outlier hospitals and intraclass correlation coefficient. Results: There were 2 882 490 inpatient hospital encounters (median [interquartile range] age, 4 [1-12] years; 1 554 024 [53.9%] boys) included. Among the 50 most prevalent and 50 most costly conditions (total, 74 conditions), 49 (66.2%) were medical, 15 (20.3%) were surgical, and 10 (13.5%) were medical/surgical. The top 10 conditions by cost accounted for $12.4 billion of $33.4 billion total costs (37.4%) and 592 815 encounters (33.8% of all encounters). Of 74 conditions, 4 conditions had an intraclass correlation coefficient (ICC) of 0.30 or higher (ie, major depressive disorder: ICC, 0.49; type 1 diabetes with complications: ICC, 0.36; diabetic ketoacidosis: ICC, 0.33; acute appendicitis without peritonitis: ICC, 0.30), and 9 conditions had an ICC higher than 0.20 (scoliosis: ICC, 0.27; hypertrophy of tonsils and adenoids: ICC, 0.26; supracondylar fracture of humerus: ICC, 0.25; cleft lip and palate: ICC, 0.24; acute appendicitis with peritonitis: ICC, 0.21). Examples of conditions high in prevalence, cost, and variation in cost included major depressive disorder (cost rank, 19; prevalence rank, 10; ICC, 0.49), scoliosis (cost rank, 6; prevalence rank, 38; ICC, 0.27), acute appendicitis with peritonitis (cost rank, 13; prevalence rank, 11; ICC, 0.21), asthma (cost rank, 10; prevalence rank, 2; ICC, 0.17), and dehydration (cost rank, 24; prevalence rank, 8; ICC, 0.18). Conclusions and Relevance: This cohort study found that major depressive disorder, scoliosis, acute appendicitis with peritonitis, asthma, and dehydration were high in prevalence, costs, and variation in cost. These results could help identify where future comparative effectiveness research in hospital pediatrics should be targeted to improve the care and outcomes of hospitalized children.

[Influence of a spontaneous bacterial peritonitis, nosocomial infections and acute-on-chronic liver failure on treatment revenues in patients with decompensated cirrhosis in Germany]. / Einfluss einer spontan bakteriellen Peritonitis, nosokomialer Infektionen und eines akut auf chronischen Leberversagens auf die Behandlungserlöse bei Patienten mit dekompensierter Leberzirrhose in Deutschland.

BACKGROUND: The economic effects of spontaneous bacterial peritonitis (SBP), nosocomial infections (nosInf) and acute-on-chronic liver failure (ACLF) have so far been poorly studied. We analyzed the impact of these complications on treatment revenues in hospitalized patients with decompensated cirrhosis. METHODS: 371 consecutive patients with decompensated liver cirrhosis, who received a paracentesis between 2012 and 2016, were included retrospectively. DRG (diagnosis-related group), "ZE/NUB" (additional charges/new examination/treatment methods), medication costs, length of hospital stay as well as different kinds of specific treatments (e. g., dialysis) were considered. Exclusion criteria included any kind of malignancy, a history of organ transplantation and/or missing accounting data. RESULTS: Total treatment costs (DRG + ZE/NUB) were higher in those with nosInf (€â€Š10,653 vs. €â€Š5,611, p < 0.0001) driven by a longer hospital stay (23 d vs. 12 d, p < 0.0001). Of note, revenues per day were not different (€â€Š473 vs. €â€Š488, p = 0.98) despite a far more complicated treatment with a more frequent need for dialysis (p < 0.0001) and high-complex care (p = 0.0002). Similarly, SBP was associated with higher total revenues (€â€Š10,307 vs. €â€Š6,659, p < 0.0001). However, the far higher effort for the care of SBP patients resulted in lower daily revenues compared to patients without SBP (€â€Š443 vs. €â€Š499, p = 0.18). ACLF increased treatment revenues to €â€Š10,593 vs. €6,369 without ACLF (p < 0.0001). While treatment of ACLF was more complicated, revenue per day was not different to no-ACLF patients (€â€Š483 vs. €â€Š480, p = 0.29). CONCLUSION: SBP, nosInf and/or ACLF lead to a significant increase in the effort, revenue and duration in the treatment of patients with cirrhosis. The lower daily revenue, despite a much more complex therapy, might indicate that these complications are not yet sufficiently considered in the German DRG system.

Factors Influencing Seeking and Reaching Care in Patients With Peritonitis in Rwanda.

BACKGROUND: Peritonitis is an emergency which frequently requires surgical intervention. The aim of this study was to describe factors influencing seeking and reaching care for patients with peritonitis presenting to a tertiary referral hospital in Rwanda. METHODS: This was a cross-sectional study of patients with peritonitis admitted to University Teaching Hospital of Kigali. Data were collected on demographics, prehospital course, and in-hospital management. Delays were classified according to the Three Delays Model as delays in seeking or reaching care. Chi square test and logistic regression were used to determine associations between delayed presentation and various factors. RESULTS: Over a 9-month period, 54 patients with peritonitis were admitted. Twenty (37%) patients attended only primary school and 15 (28%) never went to school. A large number (n = 26, 48%) of patients were unemployed and most (n = 45, 83%) used a community-based health insurance. For most patients (n = 44, 81%), the monthly income was less than 10,000 Rwandan francs (RWF) (11.90 U.S. Dollars [USD]). Most (n = 51, 94%) patients presented to the referral hospital with more than 24 h of symptoms. More than half (n = 31, 60%) of patients had more than 4 d of symptoms on presentation. Most (n = 37, 69%) patients consulted a traditional healer before presentation at the health care system. Consultation with a traditional healer was associated with delayed presentation at the referral hospital (P < 0.001). Most (n = 29, 53%) patients traveled more than 2 h to reach a health facility and this was associated with delayed presentation (P = 0.019). The cost of transportation ranged between 5000 and 1000 RWF (5.95-11.90 USD) for most patients and was not associated with delayed presentation (P = 0.449). CONCLUSIONS: In this study, most patients with peritonitis present in a delayed fashion to the referral hospital. Factors associated with seeking and reaching care included sociodemographic characteristics, health-seeking behaviors, cost of care, and travel time. These findings highlight factors associated with delays in seeking and reaching care for patients with peritonitis.

Risk of Catastrophic Health Expenditure in Rwandan Surgical Patients with Peritonitis.

BACKGROUND: Surgical procedures are cost-effective compared with various medical and public health interventions. While peritonitis often requires surgery, little is known regarding the associated costs, particularly in low- and middle-income countries. The aim of this study was to determine in-hospital charges for patients with peritonitis and if patients are at risk of catastrophic health expenditure. METHODS: As part of a larger study examining the epidemiology and outcomes of patients with peritonitis at a referral hospital in Rwanda, patients undergoing operation for peritonitis were enrolled and hospital charges were examined. The primary outcome was the percentage of patients at risk for catastrophic health expenditure. Logistic regression was used to determine the association of various factors with risk for catastrophic health expenditure. RESULTS: Over a 6-month period, 280 patients underwent operation for peritonitis. In-hospital charges were available for 245 patients. A total of 240 (98%) patients had health insurance. Median total hospital charges were 308.1 USD, and the median amount paid by patients was 26.9 USD. Thirty-three (14%) patients were at risk of catastrophic health expenditure based on direct medical expenses. Estimating out-of-pocket non-medical expenses, 68 (28%) patients were at risk of catastrophic health expenditure. Unplanned reoperation was associated with increased risk of catastrophic health expenditure (p < 0.001), whereas patients with community-based health insurance had decreased risk of catastrophic health expenditure (p < 0.001). CONCLUSIONS: The median hospital charges paid out-of-pocket by patients with health insurance were small in relation to total charges. A significant number of patients with peritonitis are at risk of catastrophic health expenditure.

Cost analysis of laparoscopic lavage compared with sigmoid resection for perforated diverticulitis in the Ladies trial.

BACKGROUND: Laparoscopic peritoneal lavage is an alternative to sigmoid resection in selected patients presenting with purulent peritonitis from perforated diverticulitis. Although recent trials have lacked superiority for lavage in terms of morbidity, mortality was not compromised, and beneficial secondary outcomes were shown. These included shorter duration of surgery, less stoma formation and less surgical reintervention (including stoma reversal) for laparoscopic lavage versus sigmoid resection respectively. The cost analysis of laparoscopic lavage for perforated diverticulitis in the Ladies RCT was assessed in the present study. METHODS: This study involved an economic evaluation of the randomized LOLA (LaparOscopic LAvage) arm of the Ladies trial (comparing laparoscopic lavage with sigmoid resection in patients with purulent peritonitis due to perforated diverticulitis). The actual resource use per individual patient was documented prospectively and analysed (according to intention-to-treat) for up to 1 year after randomization. RESULTS: Eighty-eight patients were randomized to either laparoscopic lavage (46) or sigmoid resection (42). The total medical costs for lavage were lower (mean difference € - 3512, 95 per cent bias-corrected and accelerated c.i. -16 020 to 8149). Surgical reintervention increased costs in the lavage group, whereas stoma reversal increased costs in the sigmoid resection group. Differences in favour of laparoscopy were robust when costs were varied by ±20 per cent in a sensitivity analysis (mean cost difference € - 2509 to -4438). CONCLUSION: Laparoscopic lavage for perforated diverticulitis is more cost-effective than sigmoid resection.

Beyond perforation: Influence of peritoneal contamination on clinical severity and resource utilization in children with perforated appendicitis.

PURPOSE: The purpose of the study was to explore the relationship between the degree of peritoneal contamination and postoperative resource utilization in children with complicated appendicitis. METHODS: Intraoperative findings were collected prospectively at a single children's hospital from 2012 to 2014. The degree of peritoneal contamination was categorized as either "localized" (confined to the right lower quadrant and pelvis) or "extensive" (extending to the liver). Imaging utilization, postoperative length of stay (pLOS), hospital cost, and readmission rates were compared between groups. RESULTS: Of 88 patients with complicated appendicitis, 38% had extensive contamination. Preoperative characteristics were similar between groups. Patients with extensive contamination had higher rates of postoperative imaging (58.8% vs 27.7%, P<0.01), a 50% longer median pLOS (6days [IQR 4-9] vs 4days [IQR 2-5], P=0.003), a 30% higher median hospital cost ($17,663 [IQR $12,564-$23,697] vs $13,516 [IQR $10,546-$16,686], P=0.004), and a nearly four-fold higher readmission rate (20.6% vs 5.6%, P=0.04) compared to children with localized contamination. CONCLUSION: Extensive peritoneal contamination is associated with significantly higher resource utilization compared to localized contamination in children with complicated appendicitis. These findings may have important severity-adjustment implications for reimbursement and readmission rate reporting for hospitals that serve populations where late presentation is common.

Health economic analysis of laparoscopic lavage versus Hartmann's procedure for diverticulitis in the randomized DILALA trial.

BACKGROUND: Open surgery with resection and colostomy (Hartmann's procedure) has been the standard treatment for perforated diverticulitis with purulent peritonitis. In recent years laparoscopic lavage has emerged as an alternative, with potential benefits for patients with purulent peritonitis, Hinchey grade III. The aim of this study was to compare laparoscopic lavage and Hartmann's procedure with health economic evaluation within the framework of the DILALA (DIverticulitis - LAparoscopic LAvage versus resection (Hartmann's procedure) for acute diverticulitis with peritonitis) trial. METHODS: Clinical effectiveness and resource use were derived from the DILALA trial and unit costs from Swedish sources. Costs were analysed from the perspective of the healthcare sector. The study period was divided into short-term analysis (base-case A), within 12 months, and long-term analysis (base-case B), from inclusion in the trial throughout the patient's expected life. RESULTS: The study included 43 patients who underwent laparoscopic lavage and 40 who had Hartmann's procedure in Denmark and Sweden during 2010-2014. In base-case A, the difference in mean cost per patient between laparoscopic lavage and Hartmann's procedure was €-8983 (95 per cent c.i. -16 232 to -1735). The mean(s.d.) costs per patient in base-case B were €25 703(27 544) and €45 498(38 928) for laparoscopic lavage and Hartmann's procedure respectively, resulting in a difference of €-19 794 (95 per cent c.i. -34 657 to -4931). The results were robust as demonstrated in sensitivity analyses. CONCLUSION: The significant cost reduction in this study, together with results of safety and efficacy from RCTs, support the routine use of laparoscopic lavage as treatment for complicated diverticulitis with purulent peritonitis.

Antibacterial gauzes are effective in preventing infections after percutaneous endoscopic gastrostomy placement: a retrospective analysis.

OBJECTIVES: The most common complication after percutaneous endoscopic gastrostomy (PEG) placement is peristomal wound infection (up to 40% without antibiotic prophylaxis). Single-dose parenteral prophylactic antibiotics as advised by current guidelines decrease the infection rate to 9-15%. We assume a prolonged effect of local antibiotic treatment with antibacterial gauzes. This study is the first to describe the effect of antibacterial gauzes in preventing infections in PEG without the use of antibiotics. METHODS: A retrospective data analysis was carried out of all patients with PEG insertion between January 2009 and October 2014 in the Catharina Hospital Eindhoven. Data include placement and the period of the first 2 weeks after PEG placement, and long-term follow-up. All patients received a locally applied antibacterial gauze polyhexamethylene biguanide immediately following PEG insertion for 3 days. No other antibiotics were administered. The main outcomes were wound infection, peritonitis, and necrotizing fasciitis; secondary outcomes included other complications. RESULTS: A total of 331 patients with only antibacterial gauzes were analyzed. The total number of infections 2 weeks after PEG insertion was 9.4%, including 8.2% minor and 1.2% major infections (peritonitis). No wound infection-related mortality or bacterial resistance was found. Costs are five times lower than antibiotics, and gauzes are more practical and patient friendly for use. CONCLUSION: Retrospectively, antibacterial gauzes are at least comparable with literature data on parenteral antibiotics in preventing peristomal wound infection after PEG placement, with an infection rate of 9.4%. Rates of other complications found in this study were comparable with current literature data.

Characteristics of hospitals with lowest costs in management of pediatric appendicitis.

BACKGROUND: A primary determinant of value in treating appendicitis is inpatient cost. The purpose of this study was to identify hospital-level factors that drive costs associated with the treatment of appendicitis. METHODS: Cost-to-charge ratios from the 2009 Kids' Inpatient Database gave average all-payer costs by hospital for uncomplicated appendicitis (without peritonitis, ICD-9-CM 540.9) and complicated appendicitis (generalized peritonitis, 540.0; peritoneal abscess, 540.1). The 10% of hospitals with the lowest costs were defined as low cost; the remaining 90% were defined non-low cost. Bivariate and multivariate analyses compared hospital characteristics between the two groups. RESULTS: Threshold cost dividing low cost from non-low cost for uncomplicated appendicitis was $4626; for complicated appendicitis, it was $6,026. For both conditions teaching status, lower percentage of pediatric discharges, and fewer registered nurses (RN) per 1000 adjusted patient-days predicted a hospital to be low cost. A cost benefit for medium and large hospitals and higher inpatient volume was found only for uncomplicated appendicitis. Regional effects were noted. CONCLUSIONS: The findings show the high-cost structure of hospitals that care for high volumes of children, emphasizing the need to constrain cost. There is some benefit of economies of scale, and careful attention to the numbers of nursing personnel.

Economic consequences of failure of initial antibiotic therapy in hospitalized adults with complicated intra-abdominal infections.

BACKGROUND: Initial antibiotic therapy in hospitalized adults with complicated intra-abdominal infection (cIAI) usually is empiric. We explored the economic consequences of failure of such therapy in this patient population. METHODS: Using a large U.S. multi-institutional database, we identified all hospitalized adults admitted between April 1, 2003, and March 31, 2004; who had any cIAI; underwent laparotomy, laparoscopy, or percutaneous drainage of an intra-abdominal abscess ("surgery"); and received intravenous (IV) antibiotics. Initial therapy was characterized in terms of all IV antibiotics received, on the day of or one day before initial surgery. Antibiotic failure was designated on the basis of the need for reoperation or receipt of other IV antibiotics postoperatively. Switches to narrower spectrum agents and changes in regimen prior to discharge with no other evidence of clinical failure were not counted as antibiotic failures. Using multivariable linear regression, duration of IV antibiotic therapy, hospital length of stay, and total inpatient charges were compared between patients who did and did not fail initial therapy. Mortality was compared using multivariable logistic regression. RESULTS: Among 6,056 patients who met the study entrance criteria, 22.4% failed initial antibiotic therapy. Patients who failed received an additional 5.6 days of IV antibiotic therapy (10.4 total days [95% confidence interval 10.1, 10.8] days vs. 4.8 total days [4.8, 4.9] for those not failing), were hospitalized an additional 4.6 days (11.6 total days [11.3, 11.9] vs. 6.9 total days [6.8, 7.0], respectively), and incurred $6,368 in additional inpatient charges ($16,520 [$16,131, $16,919] vs. $10,152 [$10,027, $10,280]) (all, p < 0.01). They also were more likely to die in the hospital (9.5% vs. 1.3%; multivariable odds ratio 3.58 [95% confidence interval 2.53, 5.06]). CONCLUSIONS: Failure of initial IV antibiotic therapy in hospitalized adults with cIAIs is associated with longer hospitalization, higher hospital charges, and a higher mortality rate.

Perforated appendicitis: urgency or interval surgery?

BACKGROUND: The purpose of this study was to report how conservative treatment with interval appendectomy (IA) of ruptured appendicitis with localized abscess or phlegmon affects the outcome of patients. PATIENTS AND METHODS: From January 2001 to December 2005, 121 patients with ruptured appendicitis with localized abscess or phlegmon were treated in our hospital. 104 patients underwent appendectomy (Group A); 17 patients underwent antibiotic treatment with interval appendectomy (Group B). The clinical characteristics (age and sex), laboratory data, mean time to surgery, operative time, complications, hospital days and cost of hospitalization were recorded. RESULTS: The sex, age, white blood cell count (WBC), body temperature, operation time, length of stay after surgery, first flatus, oral feeding, passage of stools, cost and overall complications (including wound infection, wound disruption, intra-abdominal abscess and enterocutaneous fistula) were not significantly different between the two groups. However, the length of stay after diagnosis established of group B was significantly longer in group B than in group A. CONCLUSION: Conservative treatment with IA is a safe and effective method to treat perforated appendicitis with localized abscess and phlegmon, but the recovery time may be longer and also the hospital stay (since diagnosis established). Thus this method is not cost-saving.

New perspectives in antibiotic prophylaxis for intra-abdominal surgery.

Effective management of intra-abdominal infections requires a combination of preoperative preparation, antibiotic prophylaxis and appropriate surgical technique. Antibacterial prophylaxis should provide coverage of all likely pathogens, including aerobic and anaerobic organisms. Whereas antibacterial combination therapy is appropriate in certain situations, single-agent prophylaxis is appropriate for the majority of patients and ampicillin/sulbactam, with its broad-spectrum anti-aerobic/anti-anaerobic activity, is an attractive prophylactic option. Surgery involving the gastrointestinal tract provides a special challenge by virtue of its high, predominantly anaerobic, bacterial load. However, the requirement for prophylaxis varies depending upon the precise site of intervention. Biliary tract surgery requires prophylaxis in high-risk patients only, whereas hepatobiliary or pancreatic surgery requires prophylaxis in all patients. Gastroduodenal operations require prophylaxis in the presence of risk factors, such as abnormal gastric acidity or bleeding. Colorectal procedures present a high risk of anaerobic infection and sepsis, and require adequate prophylaxis combined with a thorough preoperative preparation designed to reduce considerably the bacterial load of the bowel. Where peritonitis does follow intra-abdominal surgery, patients should receive antibacterial therapy commensurate with the risk of serious infection. A small proportion of patients will be at risk of severe infection and will require triple-agent therapy. However, most patients are likely to develop mild-to-moderate infections only and can be treated with a single, broad-spectrum antibiotic agent, such as ampicillin/sulbactam, a beta-lactam/beta-lactamase inhibitor.

Surgery and adjuvant therapy in patients with diffuse peritonitis: cost analysis.

In a prospective, randomized, controlled trial the effect of high dose intravenous antithrombin III and intraabdominal donor serum was analyzed in 36 patients with diffuse secondary peritonitis. The direct cost for treatment was 25,370 euros per patient, and the post acute hospital care costs and societal costs were 6273 euros. The cost for intensive care of these patients accounted for approximately 83% of the direct costs, while the expenditures for operating theater and general wards accounted for 9% each. The most expensive factors were staff, medication, and blood products. The hospital incurred a deficit of 3696 euros for each patient after reimbursement from public health insurance companies. Quality of life as assessed by the gastrointestinal quality of life index (GIQI) showed a good outcome. On average 11 quality adjusted life years (QALY) were achieved. The cost per QALY was 2631 euros. Use of adjuvant therapy was associated with a reduced duration of intensive care unit (ICU) treatment, times on mechanical respiration, and hemofiltration; the cost of treatment was reduced by 6614 euros per patient. The additional cost of antithrombin III (5155 euros) was more than offset by the savings made when adjuvant therapy was used.
