BACKGROUND We aimed to compare the performance of EQ-5D-3 L and howRu, which are short generic patient-reported outcome measures (PROMs), in assessing the outcome of hip and knee replacements, using the Oxford Hip Score (OHS) and the Oxford Knee Scores (OKS) for comparison. METHODS Outcome was assessed as the difference between pre-surgery and 6-month post-surgery scores. We used a large samp...

OBJECTIVES Existing electronic data capture options are often financially unfeasible in resource-poor settings or difficult to support technically in the field. To help facilitate large-scale multicenter studies in sub-Saharan Africa, the African Partnership for Chronic Disease Research (APCDR) has developed an open-source electronic questionnaire (EQ). STUDY DESIGN AND SETTING To assess its ...

BACKGROUND While age is a common confounder, its impact on health-related quality of life (HRQoL) after total hip replacement is uncertain. This could be due to improper statistical modeling of age in previous studies, such as treating age as a linear variable or by using age categories. We hypothesized that there is a non-linear association between age and HRQoL. METHODS We selected a nation...

Of 415 patients, 200 undergoing aortic valve replacement (AVR) and 215 undergoing AVR in combination with myocardial revascularization [coronary artery bypass grafting (CABG)], had complete preoperative health-related quality of life (HRQOL) data. From this group, 224 patients had a follow-up of one year. To assess HRQOL, the EuroQol instrument was used. The EQ-5D index score was calculated, ba...

BACKGROUND Numerous studies have identified that physical activity (PA) has positive influences on quality of life. However, there has been little domestic research about the relation of PA to health-related quality of life (HRQoL) among the general population. The purpose of this study was to evaluate the effect of PA on HRQoL in Korean adults aged 40 years or over. METHODS This cross-sectio...

OBJECTIVE To investigate whether self-rated health profiles compiled using the EuroQol group's visual analog scale (EQ VAS) are independent predictors of vascular events and major complications in people with type 2 diabetes after controlling for standard clinical risk factors. RESEARCH DESIGN AND METHODS The study is based on 7,348 individuals with a mean follow-up of 2.4 years after complet...

In this paper, we introduce a new algebra called ‘EQ-algebra’, which is an alternative algebra of truth values for formal fuzzy logics. It is specified by replacing implication as the main operation with a fuzzy equality. Namely, EQ-algebra is a semilattice endowed with a binary operation of fuzzy equality and a binary operation of multiplication. Implication is derived from the fuzzy equality ...

EQ-5D is used in cost-effectiveness studies underlying many important health policy decisions. It comprises a survey instrument describing health states across five domains, and a system of utility values for each state. The original 3-level version of EQ-5D is being replaced with a more sensitive 5-level version but the consequences of this change are uncertain. We develop a multi-equation ord...

We investigated individual differences in empathy and emotion recognition. Emotion recognition was operationalized as accuracy on the six emotions composing Ekman’s Pictures of Facial Affect. Facets of empathy were measured with the Empathy Quotient (EQ) and the empathic concern factor of the Interpersonal Reactivity Scale. Two aspects of emotion recognition were investigated: exposure length (...

BACKGROUND Anthropogenic climate change presents a major global health threat. However, the very provision of healthcare itself is associated with a significant environmental impact. Carbon footprinting techniques are increasingly used outside of the healthcare sector to assess greenhouse gas emissions and inform strategies to reduce them. AIM This study represents the first assessment of the...
