Validation of test performance characteristics and minimal clinically important difference of the 6-minute walk test in patients with idiopathic pulmonary fibrosis
SummaryBackgroundThe 6-minute walk test distance (6MWD) has been shown to be a valid and responsive outcome measure in patients with idiopathic pulmonary fibrosis (IPF). The analyses were based, however, on a single phase 3 trial and require validation in an independent cohort.ObjectiveTo confirm the performance characteristics and estimates of minimal clinically important difference (MCID) of 6MWD in an independent cohort of patients with IPF.MethodsPatients randomized to placebo in the phase 3 CAPACITY trials who had a baseline 6MWD measurement were included in these analyses. The 6MWD and other functional parameters (lung function, dyspnea, and health-related quality of life) were measured at baseline and 24-week intervals. Validity and responsiveness were examined using Spearman correlation coefficients. The MCID was estimated using distribution- and anchor-based methods.ResultsThe analysis comprised 338 patients. Baseline 6MWD was significantly correlated with lung function measures, patient-reported outcomes, and quality-of-life measures (validity). Compared with baseline 6MWD, change in 6MWD (responsiveness) showed stronger correlations with change in lung function parameters and quality-of-life measures. Dyspnea measured by the University of California San Diego Shortness of Breath Questionnaire showed the strongest correlations with 6MWD (baseline: coefficient −0.35; 48-week change: coefficient −0.37; both p < 0.001). The distribution-based analyses of MCID using standard error of measurement yielded an MCID of 37 m, and distribution-based analyses by effect size resulted in 29.2 m. The MCID by anchor-based analysis using criterion referencing (health events of hospitalization or death) was 21.7 m.ConclusionsThe 6MWD is a valid and responsive clinical endpoint, which provides objective and clinically meaningful information regarding functional status and near-term prognosis. These results confirm previous findings in an independent cohort of patients with IPF
Economic costs of chemotherapy-induced febrile neutropenia among patients with non-Hodgkin's lymphoma in European and Australian clinical practice
Background:
Economic implications of chemotherapy-induced febrile neutropenia (FN) in European and Australian clinical practice are largely unknown.
Methods:
Data were obtained from a European (97%) and Australian (3%) observational study of patients with non-Hodgkin’s lymphoma (NHL) receiving CHOP (±rituximab) chemotherapy. For each patient, each cycle of chemotherapy within the course, and each occurrence of FN within cycles, was identified. Patients developing FN in a given cycle (“FN patients”), starting with the first, were matched to those who did not develop FN in that cycle (“comparison patients”), irrespective of subsequent FN events. FN-related healthcare costs (£2010) were tallied for the initial FN event as well as follow-on care and FN events in subsequent cycles.
Results:
Mean total cost was £5776 (95%CI £4928-£6713) higher for FN patients (n = 295) versus comparison patients, comprising £4051 (£3633-£4485) for the initial event and a difference of £1725 (£978-£2498) in subsequent cycles. Among FN patients requiring inpatient care (76% of all FN patients), mean total cost was higher by £7259 (£6327-£8205), comprising £5281 (£4810-£5774) for the initial hospitalization and a difference of £1978 (£1262-£2801) in subsequent cycles.
Conclusions:
Cost of chemotherapy-induced FN among NHL patients in European and Australian clinical practice is substantial; a sizable percentage is attributable to follow-on care and subsequent FN events

Healthcare costs in women with metastatic breast cancer receiving chemotherapy as their principal treatment modality
<p>Abstract</p> <p>Background</p> <p>The economic costs of treating patients with metastatic breast cancer have been examined in several studies, but available estimates of economic burden are at least a decade old. In this study, we characterize healthcare utilization and costs in the US among women with metastatic breast cancer receiving chemotherapy as their principal treatment modality.</p> <p>Methods</p> <p>Using a large private health insurance claims database (2000-2006), we identified all women initiating chemotherapy for metastatic breast cancer with no evidence of receipt of concomitant or subsequent hormonal therapy, or receipt of trastuzumab at anytime. Healthcare utilization and costs (inpatient, outpatient, medication) were estimated on a cumulative basis from date of chemotherapy initiation ("index date") to date of disenrollment from the health plan or the end of the study period, whichever occurred first.

Local Spatial and Temporal Processes of Influenza in Pennsylvania, USA: 2003–2009
Background: Influenza is a contagious respiratory disease responsible for annual seasonal epidemics in temperate climates. An understanding of how influenza spreads geographically and temporally within regions could result in improved public health prevention programs. The purpose of this study was to summarize the spatial and temporal spread of influenza using data obtained from the Pennsylvania Department of Health's influenza surveillance system. Methodology and Findings: We evaluated the spatial and temporal patterns of laboratory-confirmed influenza cases in Pennsylvania, United States from six influenza seasons (2003-2009). Using a test of spatial autocorrelation, local clusters of elevated risk were identified in the South Central region of the state. Multivariable logistic regression indicated that lower monthly precipitation levels during the influenza season (OR = 0.52, 95% CI: 0.28, 0.94), fewer residents over age 64 (OR = 0.27, 95% CI: 0.10, 0.73) and fewer residents with more than a high school education (OR = 0.76, 95% CI: 0.61, 0.95) were significantly associated with membership in this cluster. In addition, time series analysis revealed a temporal lag in the peak timing of the influenza B epidemic compared to the influenza A epidemic. Conclusions: These findings illustrate a distinct spatial cluster of cases in the South Central region of Pennsylvania. Further examination of the regional transmission dynamics within these clusters may be useful in planning public health influenza prevention programs. © 2012 Stark et al
Medical malpractice among physicians: Who will be sued and who will pay?
This paper examines whether a physician's future claims of medical malpractice are predictable from information on the physician's recent claims history, training credentials, practice characteristics, and demographics. Data on the medical malpractice experience of 8,733 Michigan physicians between 1980 and 1989 is analyzed. We find strong evidence of repetition over time regarding who was sued and who paid claims. The worse a physician's malpractice litigation record during 1980–1984, the worse was his record during 1985–1989. Training credentials were also highly predictive of future malpractice experience. Physicians trained at lower ranked medical schools or who went through lower-ranked residency programs faced higher odds of developing adverse malpractice records, even after controlling for their previous litigation record. Growing internet access to information on these characteristics will help inform prospective patients if they wish to avoid physicians likely to be sued and likely to make payments in the future for malpractice.

US healthcare costs attributable to type A and type B influenza
While the overall healthcare burden of seasonal influenza in the United States (US) has been well characterized, the proportion of influenza burden attributable to type A and type B illness warrants further elucidation. The aim of this study was to estimate numbers of healthcare encounters and healthcare costs attributable to influenza viral strains A and B in the US during the 2001/2002 – 2008/2009 seasons. Healthcare encounters and costs in the US during the 2001/2002 – 2008/2009 seasons for influenza type A and influenza type B were estimated separately and collectively, by season and age group, based on data from published literature and secondary sources for: rates of influenza-related encounters requiring formal healthcare, unit costs of influenza-related healthcare encounters, and estimates of population size. Across 8 seasons, projected annual numbers of influenza-related healthcare encounters ranged from 11.3–25.6 million, and healthcare costs, from 5.8 billion. While the majority of influenza illness was attributable to type A strains, type B strains accounted for 37% of healthcare costs across all seasons, and as much as 66% in a single season. The outpatient burden of type B disease was considerable among persons aged 18–64 y while the hospital cost burden was highest in young children. Influenza viral strain B was associated with considerable health system burden each year during the period of interest. Increasing influenza vaccine coverage, especially with the recently approved quadrivalent products including an additional type B strain, could potentially reduce overall annual influenza burden in the US
Hospitalizations for osteoporosis-related fractures: Economic costs and clinical outcomes
Background: Osteoporotic fractures frequently require inpatient care, and are associated with elevated risks of morbidity, mortality, and re-hospitalization. A comprehensive evaluation of healthcare costs, resource utilization, and outcomes associated with osteoporosis (OP)-related fractures treated in US hospitals was undertaken. Methods: A retrospective analysis using the Premier Perspective Database (2010−2013) was conducted. Study population comprised patients aged ≥50 years hospitalized with a principal diagnosis of a closed or pathologic fracture commonly associated with OP; the first qualifying hospitalization was designated the “index admission”. Patients with evidence of major trauma, malignancy, or other non-OP conditions that may lead to pathologic fracture during the index admission were excluded. Study measures included healthcare costs (in 2013 USD), length of stay (LOS), intensive care unit (ICU) use, and mortality during the index admission, as well as 60-day fracture-related readmission. Results: A total of 268,477 patients were admitted to hospital (n = 548 hospitals) with a principal diagnosis of an OP-related fracture; mean (SD) age was 78 (11) years, 75% were female, 69% had ≥2 comorbidities, and 82% of patients had a diagnostic code for accidental fall. Among all OP-related fracture admissions, mean (95% CI) hospital cost was $12,839 (12,784–12,893) and LOS was 5.1 (5.1–5.1) days; during the admission, ICU use was 7.4% (7.3–7.5) and mortality was 1.5% (1.5–1.6), and during the 60-day post-discharge period, fracture-related readmission was 2.3% (2.2–2.4). Conclusions: Hospital costs associated with the acute treatment of OP-related fractures are substantial, especially among patients with fractures of the hip, femur, and spine. Among patients with vertebral fractures—the second most common reason for admission—mortality and ICU use were notably high, and costs and LOS were higher than among those with non-vertebral fractures (excluding hip). Interventions that are effective in reducing fracture risk have the potential to yield substantial cost savings. Keywords: Osteoporosis, Healthcare costs, Hospitalization, Length of stay, Mortalit
