BACKGROUND: The Pediatric Quality of Life Inventory™ 4.0 Short Form 15 Generic Core Scales (hereafter the PedsQL) and the Child Health Utility-9 Dimensions (CHU9D) are two generic instruments designed to measure health-related quality of life in children and adolescents in the general population and paediatric patient groups living with specific health conditions. Although the PedsQL is widely used among paediatric patient populations, presently it is not possible to directly use the scores from the instrument to calculate quality-adjusted life-years (QALYs) for application in economic evaluation because it produces summary scores which are not preference-based...

REVIEW
Rikke Søgaard, Ulrika Enemark
OBJECTIVE: To determine the relationship between cost and quality in European hospitals. METHODS: Juran's cost-quality curve served as a theoretical framework, linked to basic efficiency concepts. Based on systematic database searches, citation searches and cross-referencing, we identify 1093 empirical studies. After exclusion of studies from outside Europe (699), non-hospital settings (10 studies), lack of a cost parameter (194) or a quality parameter (27 studies), 22 studies (28 analyses) were assessed for direction of association and methodological heterogeneity...

Orthopedics is a discipline that requires a continuum of care in close collaboration with physicians, nurses, and healthcare professionals to ensure effective rehabilitation. In some cases, the wait time for a consultation may be very long, which can jeopardize the patient's rehabilitation and sometimes even cause complications that lead to a loss of autonomy. In Quebec, there is a severe shortage of healthcare professionals-and of orthopedic surgeons, in particular-specializing in musculoskeletal problems...

High frequency financial data modelling has become one of the important research areas in the field of financial econometrics. However, the possible structural break in volatile financial time series often trigger inconsistency issue in volatility estimation. In this study, we propose a structural break heavy-tailed heterogeneous autoregressive (HAR) volatility econometric model with the enhancement of jump-robust estimators. The breakpoints in the volatility are captured by dummy variables after the detection by Bai-Perron sequential multi breakpoints procedure...

How humans resolve non-trivial tradeoffs in their navigational choices between the social interactions (e.g., the presence and movements of others) and the physical factors (e.g., spatial distances, route visibility) when escaping from threats in crowded confined spaces? The answer to this question has major implications for the planning of evacuations and the safety of mass gatherings as well as the design of built environments. Due to the challenges of collecting behavioral data from naturally-occurring evacuation settings, laboratory-based virtual-evacuation experiments have been practiced in a number of studies...

INTRODUCTION: Understanding what influences where food outlets locate is important for mitigating disparities in access to healthy food outlets. However, few studies have examined how neighborhood characteristics influence the neighborhood food environment over time, and whether these relationships differ by neighborhood-level income. METHODS: Neighborhood-level data from four U.S. cities (Birmingham, AL; Chicago, IL; Minneapolis, MN; Oakland, CA) from 1986, 1993, 1996, 2001, 2006, and 2011 were used with two-step econometric models to estimate longitudinal associations between neighborhood-level characteristics (z-scores) and the log-transformed count/km(2) (density) of food outlets within real estate-derived neighborhoods...

BACKGROUND: Relatively little is known about the effects of mode of delivery on long-term health-related quality-of-life outcomes. Furthermore, no previous study has expressed these outcomes in preference-based (utility) metrics. METHODS: The study population comprised 2,161 mothers recruited from a prospective population-based study in the East Midlands of England encompassing live births and stillbirths between 32(+0) and 36(+6) weeks' gestation and a sample of term-born controls...

We report significant relations between past changes in the market correlation structure and future changes in the market volatility. This relation is made evident by using a measure of "correlation structure persistence" on correlation-based information filtering networks that quantifies the rate of change of the market dependence structure. We also measured changes in the correlation structure by means of a "metacorrelation" that measures a lagged correlation between correlation matrices computed over different time windows...

Primary care patient-centered medical homes (PCMHs) are an effective healthcare delivery model. Evidence regarding the most effective payment models for increased coordination efforts is sparse. This protocol paper describes the evaluation of an Alternative Payment Methodology (APM) implemented in a subset of Oregon community health centers (CHCs), using a prospective matched observational design. The APM is a primary care payment reform intervention that changed Oregon's Medicaid payment for several CHCs from fee-for-service reimbursement to a per-member-per-month capitated payment...

Granger causality analysis, as a time series analysis technique derived from econometrics, has been applied in an ever-increasing number of publications in the field of neuroscience, including fMRI, EEG/MEG, and fNIRS. The present study mainly focuses on the validity of "signed path coefficient Granger causality," a Granger-causality-derived analysis method that has been adopted by many fMRI researches in the last few years. This method generally estimates the causality effect among the time series by an order-1 autoregression, and defines a positive or negative coefficient as an "excitatory" or "inhibitory" influence...

Rapid industrialization in China has brought forward serious and harmful atmospheric pollution. In this study, spatial econometric analysis was used to analyze the spatial change and the driving forces behind the industrial sulfur dioxide (SO2) discharge in China from 2001 to 2014. The study found that the amount of industrial SO2 discharge (ISOD) increased first and then decreased during this period. ISOD intensity witnessed a fluctuating drop. There were large differences among intercity ISOD amount and intensity, which had various spatial patterns...

BACKGROUND: Geographical distribution of healthcare resources is an important dimension of healthcare access. Little work has been published on healthcare resource allocation patterns in China, despite public equity concerns. METHODS: Using national data from 2043 counties, this paper investigates the geographic distribution of hospital beds at the county level in China. We performed Gini coefficient analysis to measure inequalities and ordinary least squares regression with fixed provincial effects and additional spatial specifications to assess key determinants...

This study investigates causal effects of economic insecurity on subjective anxiety, food intake, and weight outcomes. A review of psychological and nutrition studies highlights the complexity of processes at work on each stage of this causal chain. Econometric analyses trace the effects along the hypothesized pathway using detailed household panel data from the Russia Longitudinal Monitoring Survey from 1994 to 2005. Economic insecurity measures serve as key explanatory variables in regressions and are instrumented by exogenous regional indicators...

BACKGROUND: Food safety is a key public health issue worldwide. This study aims to characterise existing governance mechanisms - governance structures (GSs) and food safety management systems (FSMSs) - and analyse the alignment thereof in detecting food safety hazards, based on empirical evidence from Lebanon. RESULTS: Firm-to-firm and public baseline are the dominant FSMSs applied in a large-scale, while chain-wide FSMSs are observed only in a small-scale. Most transactions involving farmers are relational and market-based in contrast to (large-scale) processors, which opt for hierarchical GSs...

Achieving a long-term food security and preventing hunger include a better nutrition through sustainable systems of production, distribution, and consumption. Nonetheless, the quest for an alternative to increasing global food supply to meet the growing demand has led to the use of poor agricultural practices that promote climate change. Given the contribution of the agricultural ecosystem towards greenhouse gas (GHG) emissions, this study investigated the causal nexus between carbon dioxide emissions and agricultural ecosystem by employing a data spanning from 1961 to 2012...

BACKGROUND: Many markets have traditionally been dominated by a few best-selling products, and this is also the case for the health care industry. However, we do not know whether the market will be more or less concentrated when health care services are delivered online (known as E-consultation), nor do we know how to reduce the concentration of the E-consultation market. OBJECTIVE: The aim of this study was to investigate the concentration of the E-consultation market and how to reduce its concentration through information disclosure mechanisms (online reputation and self-representation)...

BACKGROUND: Hyperlipidemia is a major risk factor for cardiovascular disease (CVD), affecting 73.5 million American adults. Information about health care expenditures associated with hyperlipidemia by CVD status is needed to evaluate the economic benefit of primary and secondary prevention programs for CVD. METHODS: The study sample includes 48,050 men and nonpregnant women ≥18 from 2010 to 2012 Medical Expenditure Panel Survey. A 2-part econometric model was used to estimate annual hyperlipidemia-associated medical expenditures by CVD status...

Work zones are critical parts of the transportation infrastructure renewal process consisting of rehabilitation of roadways, maintenance, and utility work. Given the specific nature of a work zone (complex arrangements of traffic control devices and signs, narrow lanes, duration) a number of crashes occur with varying severities involving different vehicle sizes. In this paper we attempt to investigate the causal factors contributing to injury severity of large truck crashes in work zones. Considering the discrete nature of injury severity categories, a number of comparable econometric models were developed including multinomial logit (MNL), nested logit (NL), ordered logit (ORL), and generalized ordered logit (GORL) models...

This paper seeks to identify the determinants of the choice of treatment of pregnant women in Cameroon. Theoretically, the methodology is based on a discrete choice model with random utility. Empirically, the econometric specification is a Nested Multinomial Logit Model. The data used comes from the Demographic Health Survey (DHS) organized in 2011 by the National Institute of Statistics. The results reveal that uneducated women or those having only a primary education prefer to meet the traditional midwives than seek modern maternal health services...
