Assessing the cost-effectiveness of integrated case management of Neglected Tropical Diseases in Liberia.

BACKGROUND: In 2017, Liberia became one of the first countries in the African region to develop and implement a national strategy for integrated case management of Neglected Tropical Diseases (CM-NTDs), specifically Buruli ulcer, leprosy, lymphatic filariasis morbidities, and yaws. Implementing this plan moves the NTD program from many countries' fragmented (vertical) disease management. This study explores to what extent an integrated approach offers a cost-effective investment for national health systems. METHODS: This study is a mixed-method economic evaluation that explores the cost-effectiveness of the integrated CM-NTDs approach compared to the fragmented (vertical) disease management. Primary data were collected from two integrated intervention counties and two non-intervention counties to determine the relative cost-effectiveness of the integrated program model vs. fragmented (vertical) care. Data was sourced from the NTDs program annual budgets and financial reports for integrated CM-NTDs and Mass Drug Administration (MDA) to determine cost drivers and effectiveness. RESULTS: The total cost incurred by the integrated CM-NTD approach from 2017 to 2019 was US$ 789,856.30, with the highest percentage of costs for program staffing and motivation (41.8%), followed by operating costs (24.8%). In the two counties implementing fragmented (vertical) disease management, approximately US$ 325,000 was spent on the diagnosis of 84 persons and the treatment of twenty-four persons suffering from NTDs. While 2.5 times as much was spent in integrated counties, 9-10 times more patients were diagnosed and treated. CONCLUSIONS: The cost of a patient being diagnosed under the fragmented (vertical) implementation is five times higher than integrated CM-NTDs, and providing treatment is ten times as costly. Findings indicate that the integrated CM-NTDs strategy has achieved its primary objective of improved access to NTD services. The success of implementing an integrated CM-NTDs approach in Liberia, presented in this paper, demonstrates that NTD integration is a cost-minimizing solution.

Inflation-Adjusted Medicare Reimbursement for Revision Hip Arthroplasty: Study Showing Significant Decrease from 2002 to 2019.

BACKGROUND: Investigations into reimbursement trends for primary and revision arthroplasty procedures have demonstrated a steady decline over the past several years. Revision total hip arthroplasty (rTHA) due to infection (rTHA-I) has been associated with higher resource utilization and complexity, but long-term inflation-adjusted data have yet to be compared between rTHA-I and rTHA due to aseptic complications (rTHA-A). The present study was performed to analyze temporal reimbursement trends regarding rTHA-I procedures compared with those for rTHA-A procedures. METHODS: The Centers for Medicare & Medicaid Services (CMS) Physician Fee Schedule Look-Up Tool was used to extract Medicare reimbursements associated with 1-stage and 2-stage rTHA-I as well as 1-stage rTHA-A procedures from 2002 to 2019. Current Procedural Terminology (CPT) codes for rTHA were grouped according to the American Academy of Orthopaedic Surgeons coding reference guide. Monetary values were adjusted for inflation using the consumer price index (U.S. Bureau of Labor Statistics; reported as 2019 U.S. dollars) and used to calculate the cumulative and average annual percent changes in reimbursement. RESULTS: Following inflation adjustment, the physician fee reimbursement for rTHA-A decreased by a mean [and standard deviation] of 27.26% ± 3.57% (from $2,209.11 in 2002 to $1,603.20 in 2019) for femoral component revision, 27.41% ± 3.57% (from $2,130.55 to $1,542.91) for acetabular component revision, and 27.50% ± 2.56% (from $2,775.53 to $2,007.61) for both-component revision. Similarly, for a 2-stage rTHA-I, the mean reimbursement declined by 18.74% ± 3.87% (from $2,063.36 in 2002 to $1,673.36 in 2019) and 24.45% ± 3.69% (from $2,328.79 to $1,755.45) for the explantation and reimplantation stages, respectively. The total decline in physician fee reimbursement for rTHA-I ($1,020.64 ± $233.72) was significantly greater than that for rTHA-A ($580.72 ± $107.22; p < 0.00001). CONCLUSIONS: Our study demonstrated a consistent devaluation of both rTHA-I and rTHA-A procedures from 2002 to 2019, with a larger deficit seen for rTHA-I. A continuation of this trend could create substantial disincentives for physicians to perform such procedures and limit access to care at the population level.

Impact of postoperative remote infection on length of stay and medical costs in hospitals in Japan.

PURPOSE: To analyze the impact of postoperative remote infections (PRIs) on medical expenditure. METHODS: The subjects of this retrospective study were 338 patients who had undergone gastroenterological surgery at one of the 20 Japanese institutions within the Japan Society for Surgical Infection (JSSI) and mainly authorized as educational institutions. The patients were allocated to 169 pairs of those with a PRI (PRI (+) group) matched with those without a PRI (PRI (-) group). PRIs included pneumonia, urinary tract infection (UTI), catheter-associated blood stream infection (CA-BSI), and antibiotic-associated enteritis. RESULTS: SSI developed in 74 of the 338 patients (22 without PRI and 52 with PRI). The SSI incidence was significantly higher in the PRI (+) group (p < 0.001). The difference in the median postoperative length of hospital stay was 15 days, indicating a significant prolongation in the PRI (+) group (p < 0.001). The PRI (+) group also had a higher rate of inter-hospital transfer (p < 0.01) and mortality (p < 0.001). Similarly, the difference in median postoperative medical fees was $6832.3, representing a significant increase in the PRI (+) group (p < 0.001). CONCLUSIONS: The postoperative length of hospital stay is longer and the postoperative medical expenditure is higher for patients with a PRI than for those without a PRI.

A one health framework to estimate the cost of antimicrobial resistance.

OBJECTIVES/PURPOSE: The costs attributable to antimicrobial resistance (AMR) remain theoretical and largely unspecified. Current figures fail to capture the full health and economic burden caused by AMR across human, animal, and environmental health; historically many studies have considered only direct costs associated with human infection from a hospital perspective, primarily from high-income countries. The Global Antimicrobial Resistance Platform for ONE-Burden Estimates (GAP-ON€) network has developed a framework to help guide AMR costing exercises in any part of the world as a first step towards more comprehensive analyses for comparing AMR interventions at the local level as well as more harmonized analyses for quantifying the full economic burden attributable to AMR at the global level. METHODS: GAP-ON€ (funded under the JPIAMR 8th call (Virtual Research Institute) is composed of 19 international networks and institutions active in the field of AMR. For this project, the Network operated by means of Delphi rounds, teleconferences and face-to-face meetings. The resulting costing framework takes a bottom-up approach to incorporate all relevant costs imposed by an AMR bacterial microbe in a patient, in an animal, or in the environment up through to the societal level. RESULTS: The framework itemizes the epidemiological data as well as the direct and indirect cost components needed to build a realistic cost picture for AMR. While the framework lists a large number of relevant pathogens for which this framework could be used to explore the costs, the framework is sufficiently generic to facilitate the costing of other resistant pathogens, including those of other aetiologies. CONCLUSION: In order to conduct cost-effectiveness analyses to choose amongst different AMR-related interventions at local level, the costing of AMR should be done according to local epidemiological priorities and local health service norms. Yet the use of a common framework across settings allows for the results of such studies to contribute to cumulative estimates that can serve as the basis of broader policy decisions at the international level such as how to steer R&D funding and how to prioritize AMR amongst other issues. Indeed, it is only by building a realistic cost picture that we can make informed decisions on how best to tackle major health threats.

The practice of evaluating epidemic response in humanitarian and low-income settings: a systematic review.

BACKGROUND: Epidemics of infectious disease occur frequently in low-income and humanitarian settings and pose a serious threat to populations. However, relatively little is known about responses to these epidemics. Robust evaluations can generate evidence on response efforts and inform future improvements. This systematic review aimed to (i) identify epidemics reported in low-income and crisis settings, (ii) determine the frequency with which evaluations of responses to these epidemics were conducted, (iii) describe the main typologies of evaluations undertaken and (iv) identify key gaps and strengths of recent evaluation practice. METHODS: Reported epidemics were extracted from the following sources: World Health Organization Disease Outbreak News (WHO DON), UNICEF Cholera platform, Reliefweb, PROMED and Global Incidence Map. A systematic review for evaluation reports was conducted using the MEDLINE, EMBASE, Global Health, Web of Science, WPRIM, Reliefweb, PDQ Evidence and CINAHL Plus databases, complemented by grey literature searches using Google and Google Scholar. Evaluation records were quality-scored and linked to epidemics based on time and place. The time period for the review was 2010-2019. RESULTS: A total of 429 epidemics were identified, primarily in sub-Saharan Africa, the Middle East and Central Asia. A total of 15,424 potential evaluations records were screened, 699 assessed for eligibility and 132 included for narrative synthesis. Only one tenth of epidemics had a corresponding response evaluation. Overall, there was wide variability in the quality, content as well as in the disease coverage of evaluation reports. CONCLUSION: The current state of evaluations of responses to these epidemics reveals large gaps in coverage and quality and bears important implications for health equity and accountability to affected populations. The limited availability of epidemic response evaluations prevents improvements to future public health response. The diversity of emphasis and methods of available evaluations limits comparison across responses and time. In order to improve future response and save lives, there is a pressing need to develop a standardized and practical approach as well as governance arrangements to ensure the systematic conduct of epidemic response evaluations in low-income and crisis settings.

Disparities in United States hospitalizations for serious infections in patients with and without opioid use disorder: A nationwide observational study.

BACKGROUND: Patients with opioid use disorder (OUD) who are hospitalized for serious infections requiring prolonged intravenous antibiotics may face barriers to discharge, which could prolong hospital length of stay (LOS) and increase financial burden. We investigated differences in LOS, discharge disposition, and charges between hospitalizations for serious infections in patients with and without OUD. METHODS AND FINDINGS: We utilized the 2016 National Inpatient Sample-a nationally representative database of all discharges from US acute care hospitals. The population of interest was all hospitalizations for infective endocarditis, epidural abscess, septic arthritis, or osteomyelitis. The exposure was OUD, and the primary outcome was LOS until discharge, assessed by using a competing risks analysis to estimate adjusted hazard ratios (aHRs). Adjusted odds ratio (aOR) of discharge disposition and adjusted differences in hospital charges were also reported. Of 95,470 estimated hospitalizations for serious infections (infective endocarditis, epidural abscess, septic arthritis, and osteomyelitis), the mean age was 49 years and 35% were female. 46% had Medicare (government-based insurance coverage for people age 65+ years), and 70% were non-Hispanic white. After adjustment for potential confounders, OUD was associated with a lower probability of discharge at any given LOS (aHR 0.61; 95% CI 0.59-0.63; p < 0.001). OUD was also associated with lower odds of discharge to home (aOR 0.38; 95% CI 0.33-0.43; p < 0.001) and higher odds of discharge to a post-acute care facility (aOR 1.85; 95% CI 1.57-2.17; p < 0.001) or patient-directed discharge (also referred to as "discharge against medical advice") (aOR 3.47; 95% CI 2.80-4.29; p < 0.001). There was no significant difference in average total hospital charges, though daily hospital charges were significantly lower for patients with OUD. Limitations include the potential for unmeasured confounders and the use of billing codes to identify cohorts. CONCLUSIONS: Our findings suggest that among hospitalizations for some serious infections, those involving patients with OUD were associated with longer LOS, higher odds of discharge to post-acute care facilities or patient-directed discharge, and similar total hospital charges, despite lower daily charges. These findings highlight opportunities to improve care for patients with OUD hospitalized with serious infections, and to reduce the growing associated costs.

What Is the Financial Impact of Orthopaedic Sequelae of Intravenous Drug Use on Urban Tertiary-care Centers?

BACKGROUND: Orthopaedic sequelae such as skin and soft-tissue abscesses are frequent complications of intravenous drug use (IVDU) and comprise many of the most common indications for emergency room visits and hospitalizations within this population. Urban tertiary-care and safety-net hospitals frequently operate in challenging economic healthcare environments and are disproportionately tasked with providing care to this largely underinsured patient demographic. Although many public health initiatives have been instituted in recent years to understand the health impacts of IVDU and the spreading opioid epidemic, few efforts have been made to investigate its economic impact on healthcare systems. The inpatient treatment of orthopaedic sequelae of IVDU is a high-cost healthcare element that is critically important to understand within the current national context of inflationary healthcare costs. QUESTIONS/PURPOSES: (1) What were the total healthcare costs incurred and total hospital reimbursements received in the treatment of extraspinal orthopaedic sequelae of IVDU? (2) What were the total healthcare costs incurred and total hospital reimbursements received in the treatment of spinal orthopaedic sequelae of IVDU? (3) How did patient insurance status effect the economic burden of orthopaedic sequelae of IVDU? METHODS: An internal departmental record of all successive patients requiring inpatient treatment of orthopaedic sequelae of IVDU was initiated at Boston Medical Center (Boston, MA, USA) in 2012 and MetroHealth Medical Center (Cleveland, OH, USA) in 2015. A total of 412 patient admissions between 2012 to 2017 to these two safety-net hospitals (n = 236 and n = 176, respectively) for orthopaedic complications of IVDU were included in the study. These sequelae included cellulitis, cutaneous abscess, bursitis, myositis, tenosynovitis, septic arthritis, osteomyelitis, and epidural abscess. Patients were included if they were older than 18 years of age, presented to the emergency department for management of a musculoskeletal infection secondary to IVDU, and required inpatient orthopaedic treatment during their admission. Exclusion criteria included all patients presenting with a musculoskeletal infection not directly secondary to active IVDU. Patients presenting with an epidural abscess (Boston Medical Center, n = 36) were evaluated separately to explore potential differences in costs within this subgroup. A robust retrospective financial analysis was performed using internal financial databases at each institution which directly enumerated all true hospital costs associated with each patient admission, independent of billed hospital charges. All direct, indirect, variable, and fixed hospital costs were individually summed for each hospitalization, constituting a true "bottom-up" micro-costing approach. Labor-based costs were calculated through use of time-based costing; for instance, the cost of nursing labor care associated with a patient admission was determined through ascription of the median hospital cost of a registered nurse within that department (that is, compensation for salary plus benefits) to the total length of nursing time needed by that patient during their hospitalization. Primary reimbursements reflected the true monetary value received by the study institutions from insurers and were determined through the total adjusted payment for each inpatient admission. All professional fees were excluded. A secondary analysis was performed to assess the effect of patient insurance status on hospital costs and reimbursements for each patient admission. RESULTS: The mean healthcare cost incurred for the treatment of extraspinal orthopaedic sequelae of IVDU was USD 9524 ± USD 1430 per patient admission. The mean hospital reimbursement provided for the treatment of these extraspinal sequelae was USD 7678 ± USD 1248 per patient admission. This resulted in a mean financial loss of USD 1846 ± USD 1342 per patient admission. The mean healthcare cost incurred at Boston Medical Center for the treatment of epidural abscesses secondary to IVDU was USD 44,357 ± USD 7384 per patient. Hospital reimbursements within this subgroup were highly dependent upon insurance status. The median (range) reimbursement provided for patients possessing a unique hospital-based nonprofit health plan (n = 4) was USD 103,016 (USD 9022 to USD 320,123), corresponding to a median financial gain of USD 24,904 (USD 2289 to USD 83,079). However, the mean reimbursement for all other patients presenting with epidural abscesses (n = 32) was USD 30,429 ± USD 5278, corresponding to a mean financial loss of USD 5768 ± USD 4861. A secondary analysis demonstrated that treatment of extraspinal orthopaedic sequelae of IVDU for patients possessing Medicaid insurance (n = 309) resulted in a financial loss of USD 2813 ± USD 1593 per patient admission. Conversely, treatment of extraspinal orthopaedic sequelae for patients possessing non-Medicaid insurance (n = 67) generated a mean financial gain of USD 2615 ± USD 1341 per patient admission. CONCLUSIONS: Even when excluding all professional fees, the inpatient treatment of orthopaedic sequelae of IVDU resulted in substantial financial losses driven primarily by high proportions of under- and uninsured people within this patient population. These financial losses may be unsustainable for medical centers operating in challenging economic healthcare landscapes. The development of novel initiatives and support of existing programs aimed at mitigating the health-related and economic impact of IVDU must remain a principal priority of healthcare providers and policymakers in coming years. Advocacy for the expansion of Medicaid accountable care organizations and national syringe service programs (SSPs), and the development of specialized outpatient wound and abscess clinics at healthcare centers may help to substantially alleviate the economic burden of the orthopaedic sequelae of IVDU. LEVEL OF EVIDENCE: Level, IV, economic and decision analyses.

Health Care Costs Associated to Type of Feeding in the First Year of Life.

BACKGROUND: Breastfeeding is associated with lower risk of infectious diseases, leading to fewer hospital admissions and pediatrician consultations. It is cost saving for the health care system, however, it is not usually estimated from actual cohorts but via simulation studies. METHODS: A cohort of 970 children was followed-up for twelve months. Data on mother characteristics, pregnancy, delivery and neonate characteristics were obtained from medical records. The type of neonate feeding at discharge, 2, 4, 6, 9 and 12 months of life was reported by the mothers. Infectious diseases diagnosed in the first year of life, hospital admissions, primary care and emergency room consultations and drug treatments were obtained from neonate medical records. Health care costs were attributed using public prices and All Patients Refined-Diagnosis Related Groups (APR-DRG) classification. RESULTS: Health care costs in the first year of life were higher in children artificially fed than in those breastfed (1339.5€, 95% confidence interval (CI): 903.0-1775.0 for artificially fed vs. 443.5€, 95% CI: 193.7-694.0 for breastfed). The breakdown of costs also shows differences in primary care consultations (295.7€ for formula fed children vs. 197.9€ for breastfed children), emergency room consultations (260.1€ for artificially fed children vs. 196.2€ for breastfed children) and hospital admissions (791.6€ for artificially fed children vs. 86.9€ for breastfed children). CONCLUSIONS: Children artificially fed brought about more health care costs related to infectious diseases than those exclusively breastfed or mixed breastfed. Excess costs were caused in hospital admissions, primary care consultations, emergency room consultations and drug consumption.

Comparison of infection-related hospitalization risk and costs in tumor necrosis factor inhibitor-experienced patients with rheumatoid arthritis (RA) treated with abatacept or other targeted disease-modifying anti-rheumatic drugs (tDMARDs).

Background: Evidence on the cost and risk of infection-related hospitalizations associated with targeted disease-modifying anti-rheumatic drugs (tDMARDs) in patients with RA previously treated with a tumor necrosis factor inhibitor (TNFi) is limited. This study compared the risk and cost of infection-related hospitalizations in commercially insured TNFi-experienced RA patients receiving abatacept, TNFi, or another non-TNFi.Methods: A retrospective observational study was conducted using 2 large insurance claims databases (1 January 2009-30 June 2017). Adult TNFi-experienced RA patients initiating a subsequent tDMARD (initiation date of tDMARD = index date) with 12 months of continuous enrollment pre-index date, and who had ≥1 inpatient or ≥2 outpatient medical RA claims on 2 different dates were included. Abatacept was compared to TNFis (adalimumab, certolizumab pegol, etanercept, golimumab, and infliximab) and other non-TNFis (tocilizumab, rituximab, and tofacitinib). Cox proportional hazards models estimated the adjusted risk for infection-related hospitalization; costs were calculated on a per-member-per-month (PMPM) and per-patient-per-month (PPPM) basis using generalized linear models.Results: More patients in the abatacept cohort had an infection-related hospitalization at baseline (4.5%) vs TNFis (2.0%, p < .0001) and other non-TNFis (3.6%, p = .2619). However, during follow-up abatacept patients had fewer infection-related hospitalizations (abatacept: 2.8%, TNFi: 3.7% and other non-TNFis: 5.2%; p < .05). Regression results indicated that compared to patients on abatacept, patients receiving a TNFi [HR: 1.6 (95% CI: 1.1, 2.2)] and other non-TNFis [HR: 1.9 (95% CI: 1.3, 2.8)] had a significantly higher risk of infection-related hospitalization. Abatacept PMPM costs were lowest ($0.25 vs $0.39 and $0.43 for TNFi and other non-TNFi respectively). Mean PPPM (95% CI) cost in the follow-up was lower for abatacept compared to TNFi ($73 vs. $115; p = .042), and other non-TNFi ($73 vs. $125; p = .039).Conclusions: There were significantly lower infection-related hospitalizations and associated costs in TNF-experienced RA patients treated with abatacept than TNFis and other non-TNFis.

The cost of a "benign" condition: Healthcare utilization and infectious outcomes in young children with primary autoimmune neutropenia.

BACKGROUND: Autoimmune neutropenia (AIN) is a common cause of chronic neutropenia in childhood. Despite an expected benign clinical course, many patients undergo extensive evaluation. Data on healthcare utilization and rates of bloodstream infections in young patients with AIN are limited. METHODS: All patients with a diagnosis code of leukopenia, neutropenia, or AIN followed within the outpatient hematology clinic of a single institution from 2014 to 2016 were identified. Patients aged ≤5 years with absolute neutrophil count (ANC) ≤500/µL persisting for ≥3 months, a clinical diagnosis of AIN, and documented resolution of neutropenia were included. Data on clinical management, including infectious outcomes and emergency center (EC) encounters, were collected. RESULTS: Forty-three patients with AIN (18 male [42%], median age at diagnosis 12 months) met eligibility criteria. Children were followed by hematology for a median duration of 18 (range, 2-85) months. Diagnostic evaluations were variable. Thirty patients (70%) had ≥ 1 EC encounters for evaluation of isolated fever with a total of 113 EC encounters for the overall cohort. Patients with ANC < 500/µL and isolated fever were admitted for observation, which resulted in 24 hospitalizations in 16 patients. Of 138 blood cultures drawn, two were positive, both later determined to be contaminants. CONCLUSION: At a large tertiary care center, no bloodstream infections were identified in a cohort of 43 children with AIN presenting to the EC for assessment of fever. A less-intensive, more cost-effective management paradigm, which continues to prioritize patient safety, among young children with AIN is needed.

The Result of Treatment of Deep Neck Infection in Patients Referred According to Public Health System.

There are many factors that result in the treatment of deep neck infection (DNI). This study aims to compare the results of DNI treatment between referred and walk-in patients. This retrospective cohort study reviewed the data of 282 DNI patients. The peritonsillar abscesses and limited intraoral abscesses were excluded. The outcome of treatment such as duration of hospital stay, the expense of treatment, morbidity, and mortality were reviewed during staying in the hospital. A total of 282 patients were included in this study, there were 152 referred patients and 130 walk-in patients. Patients who were sent to have treatment results were not significantly different from those who had come directly to the hospital regardless of the length of stay, the cost of medical treatment, complications, and death due to complications with sepsis (P = .013). However, the referred patients exhibited a risk to have sepsis 1.1 times more than the patients who went straight to the medical specialists (univariate analysis risk ratio [RR]: 1.1, 95% confidence interval [CI]: 0.8-1.3; P = .620). The results were confirmed in the multivariate analysis after adjusting for age, gender, diabetes, chronic renal failure, cirrhosis, and dental care. It was found that the risk to have sepsis in the "refer in" group was 1.1 times more than the other group (multivariate analysis RR: 1.1, 95% CI: 0.8-1.3; P = .658). In conclusion, the results of treatment in referred patients were not different from walk-in patients. Deep neck infection patients at hospitals that do not have a specialized doctor will receive appropriate treatment because of the effective DNI referral system according to public health systems. However, in referred patients, sepsis should be maintained prior to delivery.

Clinical and economic burden of infections in hospitalized solid organ transplant recipients compared with the general population in Canada - a retrospective cohort study.

Infections continue to be a major cause of post-transplant morbidity and mortality, requiring increased health services utilization. Estimates on the magnitude of this impact are relatively unknown. Using national administrative databases, we compared mortality, acute care health services utilization, and costs in solid organ transplant (SOT) recipients to nontransplant patients using a retrospective cohort of hospitalizations in Canada (excluding Manitoba/Quebec) between April-2009 and March-2014, with a diagnosis of pneumonia, urinary tract infection (UTI), or sepsis. Costs were analyzed using multivariable linear regression. We examined 816 324 admissions in total: 408 352 pneumonia; 328 066 UTI's; and 128 275 sepsis. Unadjusted mean costs were greater in SOT compared to non-SOT patients with pneumonia [(C$14 923 ± C$29 147) vs. (C$11 274 ± C$18 284)] and sepsis [(C$23 434 ± C$39 685) vs. (C$20 849 ± C$36 257)]. Mortality (7.6% vs. 12.5%; P < 0.001), long-term care transfer (5.3% vs. 16.5%; P < 0.001), and mean length of stay (11.0 ± 17.7 days vs. 13.1 ± 24.9 days; P < 0.001) were lower in SOT. More SOT patients could be discharged home (63.2% vs. 44.3%; P < 0.001), but required more specialized care (23.5% vs. 16.1%; P < 0.001). Adjusting for age and comorbidities, hospitalization costs for SOT patients were 10% (95% CI: 8-12%) lower compared to non-SOT patients. Increased absolute hospitalization costs for these infections are tempered by lower adjusted costs and favorable clinical outcomes.

County-Level Socioeconomic Disparities in Use of Medical Services for Management of Infections by Medicare Beneficiaries With Diabetes-United States, 2012.

OBJECTIVE: To assess county-level socioeconomic disparities in medical service usage for infections among Medicare beneficiaries with diabetes (MBWDs) who had fee-for-service health insurance claims during 2012. DESIGN: We used Medicare claims data to calculate percentage of MBWDs with infections. SETTING: Medicare beneficiaries. PARTICIPANTS: We estimated the percentage of MBWDs who used medical services for each of 3 groups of infections by sex and quintiles of the prevalence of social factors in the person's county of residence: anatomic site-specific infections; pathogen-specific infections; and HHST infections (human immunodeficiency virus/acquired immunodeficiency syndrome, viral hepatitis, sexually transmitted diseases, and tuberculosis). MAIN OUTCOME MEASURES: Using quintiles of county-specific socioeconomic determinants, we calculated absolute and relative disparities in each group of infections for male and female MBWDs. We also used regression-based summary measures to estimate the overall average absolute and relative disparities for each infection group. RESULTS: Of the 4.5 million male MBWDs, 15.8%, 25.3%, and 2.7% had 1 or more site-specific, pathogen-specific, and HHST infections, respectively. Results were similar for females (n = 5.2 million). The percentage of MBWDs with 1 or more infections in each group increased as social disadvantage in the MBWDs' county of residence increased. Absolute and relative county-level socioeconomic disparities in receipt of medical services for 1 or more infections (site- or pathogen-specific) were 12.9 or less percentage points and 65.5% or less, respectively. For HHST infections, percentage of MBWDs having 1 or more HHST infections for persons residing in the highest quintile (Q5) was 3- to 4-fold higher (P < .001) than persons residing in the lowest quintile (Q1). CONCLUSIONS: Infection burden among MBWDs is generally associated with county-level contextual socioeconomic disadvantage, and the extent of health disparities varies by infection category, socioeconomic factor, and quintiles of socioeconomic disadvantage. The findings imply ongoing need for efforts to identify effective interventions for reducing county-level social disparities in infections among patients with diabetes.

Access, knowledge and experience with fluorodeoxyglucose positron emission tomography/computed tomography in infection management: a survey of Australia and New Zealand infectious diseases physicians and microbiologists.

BACKGROUND: Despite fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) being funded only for staging and restaging of some malignancies in Australia, there is evidence of benefit of FDG-PET/CT for infection indications such as pyrexia of unknown origin (PUO), prolonged neutropenic fever (NF) and prosthetic device infection. AIM: To evaluate the current knowledge, utilisation of and gaps in access to FDG-PET/CT for infectious indications by Australasian infectious diseases (ID) physicians and microbiologists. METHODS: An online survey was administered to ID and microbiology doctors practising in adult medicine in Australia and New Zealand through two established email networks. Using targeted questions and case-based examples, multiple themes were explored, including access to FDG-PET/CT, use and perceived benefit of FDG-PET/CT in diagnosis and monitoring of non-malignant conditions such as NF and PUO, and barriers to clinical use of FDG-PET/CT. RESULTS: A response was received from 120 participants across all states and territories. Onsite and offsite FDG-PET/CT access was 63% and 31% respectively. Eighty-six percent reported using FDG-PET/CT for one or more infection indications and all had found it clinically useful, with common indications being PUO, prosthetic device infections and use in the immunocompromised host for prolonged NF and invasive fungal infection. Thirty-eight percent reported barriers in accessing FDG-PET/CT for infection indications and 76% would utilise FDG-PET/CT more frequently if funding existed for infection indications. CONCLUSION: Access to FDG-PET/CT in Australia and New Zealand is modest and is limited by lack of reimbursement for infection indications. There is discrepancy between recognised ID indications for FDG-PET/CT and funded indications.

Use of physician billing claims to identify infections in children.

While medical records have detailed information, they are limited in reach to the availability and accessibility of those records. On the other hand, administrative data while limited in scope, have a much further reach in coverage of an entire population. However, few studies have validated the use of administrative data for identifying infections in pediatric populations. Pediatric patients from Ontario, Canada aged <18 years were randomly sampled from the Electronic Medical Record Administrative data Linked Database (EMRALD). Using physician diagnoses from the electronic medical record (EMR) as the reference standard, we determined the criterion validity of physician billing claims in administrative data for identifying infectious disease syndromes from 2012 to 2014. Diagnosis codes were assessed by infection category (respiratory, skin and soft tissue, gastrointestinal, urinary tract and otitis externa) and for all infections combined. Sensitivity analyses assessed the performance if patients had more than one reason to visit the physician. We analysed 2,139 patients and found 33.3% of all visits were for an infection, and respiratory infections accounted for 67.6% of the infections. When we combined all infection categories, sensitivity was 0.74 (95% CI 0.70-0.77), specificity was 0.95 (95% CI 0.93-0.96), positive predictive value (PPV) was 0.87 (95% CI 0.84-0.90), and negative predictive value (NPV) was 0.88 (95% CI 0.86-0.89). For respiratory infections, sensitivity was 0.77 (95% CI 0.73-0.81), specificity was 0.96 (95% CI 0.95-0.97), PPV was 0.85 (95% CI 0.81-0.88), and NPV was 0.94 (95% CI 0.92-0.95). Similar performance was observed for skin and soft tissue, gastrointestinal, urinary tract, and otitis externa infections, but with lower sensitivity. Performance measures were highest when the patient visited the physician with only one health complaint. We found when using linked EMR data as the reference standard, administrative billing codes are reasonably accurate in identifying infections in a pediatric population.

Burden of Infections Among Chronic Myeloid Leukemia Patients Receiving Dasatinib or Nilotinib: A Real-World Retrospective Healthcare Claims Study in the United States.

INTRODUCTION: Tyrosine kinase inhibitors (TKI) have been demonstrated to prolong survival in patients with chronic myeloid leukemia (CML). However, TKIs may be associated with an increased risk of infections. This study compared healthcare resource utilization (HRU) and costs among patients with CML receiving dasatinib or nilotinib, with a focus on infection-related economic outcomes. METHODS: Two large administrative databases were used to identify adult patients newly diagnosed with CML who initiated dasatinib or nilotinib as first- (1L) or second-line (2L) therapy and were classified into the following 1L (dasatinib 1L/nilotinib 1L cohorts) or 2L (dasatinib 2L/nilotinib 2L) cohorts based on the initiated 1L/2L TKI therapy. Infection-related HRU and healthcare costs were compared between cohorts, separately for 1L and 2L. RESULTS: Cohorts included 1156 patients in the dasatinib 1L and 677 patients in the nilotinib 1L cohorts, 322 patients in the dasatinib 2L, and 207 in the nilotinib 2L cohorts. In 1L and 2L, infection-related HRU was higher for dasatinib than nilotinib cohorts. Infection-related inpatient (IP) days constituted a larger proportion of all-cause IP days in the 1L/2L dasatinib than 1L/2L nilotinib cohorts (dasatinib 1L/2L: 53%/58%; nilotinib 1L/2L: 50%/46%). Compared to the nilotinib cohort, the dasatinib cohort had higher all-cause total costs per patient per year by US$17,901 in 1L and $28,625 in 2L. Of the total cost difference, infection-related were $6048 (34%) in 1L and $28,192 (99%) in 2L, largely driven by IP cost differences (1L/2L: 96%/98%). CONCLUSIONS: Dasatinib was associated with higher HRU and healthcare costs compared to nilotinib, particularly related to infections. FUNDING: Novartis Pharmaceutical Corporation.

Emergency Department disposition decisions and associated mortality and costs in ICU patients with suspected infection.

BACKGROUND: Following emergency department (ED) assessment, patients with infection may be directly admitted to the intensive care unit (ICU) or alternatively admitted to hospital wards or sent home. Those admitted to the hospital wards or sent home may experience future deterioration necessitating ICU admission. METHODS: We used a prospectively collected registry from two hospitals within a single tertiary care hospital network between 2011 and 2014. Patient information, outcomes, and costs were stored in the hospital data warehouse. Patients were categorized into three groups: (1) admitted directly from the ED to the ICU; (2) initially admitted to the hospital wards, with ICU admission within 72 hours of initial presentation; or (3) sent home from the ED, with ICU admission within 72 hours of initial presentation. Using multivariable logistic regression, we sought to compare outcomes and total costs between groups. Total costs were evaluated using a generalized linear model. RESULTS: A total of 657 patients were included; of these, 338 (51.4%) were admitted directly from the ED to the ICU, 246 (37.4%) were initially admitted to the wards and then to the ICU, and 73 (11.1%) were initially sent home and then admitted to the ICU. In-hospital mortality was lowest among patients admitted directly to the ICU (29.5%), as compared with patients admitted to the ICU from wards (42.7%) or home (61.6%) (P < 0.001). As compared with direct ICU admission, disposition to the ward was associated with an adjusted OR of 1.75 (95% CI, 1.22-2.50; P < 0.01) for mortality, and disposition home was associated with an adjusted OR of 4.02 (95% CI, 2.32-6.98). Mean total costs were lowest among patients directly admitted to the ICU ($26,748), as compared with those admitted from the wards ($107,315) and those initially sent home ($71,492) (P < 0.001). Cost per survivor was lower among patients directly admitted to the ICU ($37,986) than either those initially admitted to the wards ($187,230) or those sent home ($186,390) (P < 0.001). CONCLUSIONS: In comparison with direct admission to the ICU, patients with suspected infection admitted to the ICU who have previously been discharged home or admitted to the ward are associated with higher in-hospital mortality and costs.

The Cost of Complications Following Major Resection of Malignant Neoplasia.

BACKGROUND: Rising healthcare costs have led to increased focus on the need to achieve a higher "value of care." As value-maximization efforts expand to include more complex surgical patients, evidence to support meaningful implementation of complication-based initiatives is lacking. The objective of this study was to compare incremental costs of complications following major gastrointestinal (GI) resections for organ-specific malignant neoplasia using nationally representative data. METHODS: National (Nationwide) Inpatient Sample data, 2001-2014, were queried for adult (≥ 18 years) patients undergoing major resections for malignant neoplasia. Based on system-based complications considered relevant to the long-term treatment of GI disease, stratified differences in risk-adjusted incremental hospital costs and complication probabilities were compared. Differences in surgical outcomes and costs over time were also assessed. RESULTS: A total of 293,967 patients were included, weighted to represent 1,408,117 patients nationwide. One fourth (26.1%; 95% CI, 25.7-26.4%) experienced ≥ 1 pre-discharge complication (range, 45.3% esophagectomy to 24.0% rectal resection). Resultant annual risk-adjusted incremental hospital costs totaled $540 million nationwide (19.5% of the overall cost of care and an average of $20,900 per patient). Costs varied substantially with both cancer/resection type and complication group, ranging from $76.7 million for colectomies with infectious complications to $0.2 million for rectal resections with urinary complications. For each resection type, infectious ($154.7 million), GI ($85.5 million), and pulmonary ($77.9 million) complications were among the most significant drivers of increased hospital cost. CONCLUSIONS: Quantifying and comparing the impact of complications on an indication-specific level in more complex patients offers an important step toward allowing providers/payers to meaningfully prioritize the design of novel and adaptation of existing value-maximization approaches.

Economic burden associated with adverse events of special interest in patients with relapsed Philadelphia chromosome-negative B-cell acute lymphoblastic leukemia in the United States.

BACKGROUND: Infections, cytopenia, and gastrointestinal (GI) toxicity are adverse events of special interest (AESI) affecting most relapsed Philadelphia chromosome-negative (Ph-) B-cell acute lymphocytic leukemia (ALL) patients. This study quantified real-world rates and economic burden of these events among relapsed Ph- B-cell ALL patients in the United States. METHODS: Adults with relapsed Ph- B-cell ALL during 1 April 2009-31 October 2016 were selected from MarketScan® healthcare claims databases. Outcomes included proportions of patients with AESIs and AESI-related costs during 100 days after relapsed hospitalization. RESULTS: Of 400 relapsed Ph- B-cell ALL patients, 92.5% experienced ≥1 AESI during the median 100-day follow-up, of which 64.6% had infections, 94.6% cytopenia, and 46.2% GI toxicities. Mean (SD; median) AESI-related total cost per patient during follow-up was $197,213 ($308,551; $105,731), with a mean of 2 AESI-related hospitalizations comprising 32.2 inpatient days. Mean (SD; median) healthcare costs were highest for infections ($164,461 [$347,083; $64,528]), followed by cytopenia ($125,210 [$165,141; $67,475]) and GI events ($11,652 [$40,231; $1349]). CONCLUSION: The economic burden of AESIs is substantial, with infections the most expensive, followed by cytopenia and GI toxicity. New therapies that can improve outcomes in relapsed Ph- B-cell ALL while offering a favorable safety profile are needed.
