OBJECTIVE To compare the feasibility, convergent and clinical validity of three commonly used burden scales: Caregiver Strain Index (CSI), Caregiver Reaction Assessment (CRA) and Sense of Competence Questionnaire (SCQ), with a self-developed single question on self-rated burden (SRB). SUBJECTS Stroke patients receiving support from an informal caregiver(More)
Proton relaxation times T1 and T2 of macromolecular solutions, bovine brain tissues, and experimental cat brain edema tissues were studied as a function of water concentration, protein concentration, and temperature. A linear relation was found between the inverse of the weight fraction of tissue water and the spin-lattice relaxation rate, R1, based on a(More)
The diaminocyclohexane platinum (Pt(DACH)) derivatives ormaplatin and oxaliplatin have caused severe and dose-limiting peripheral sensory neurotoxicity in a clinical trial. We hypothesized that this toxicity could vary in relation to the biotransformation and stereochemistry of these Pt(DACH) derivatives. We prepared pure R,R and S,S enantiomers of(More)
The societal perspective in economic evaluations dictates that costs and effects of informal care are included in the analyses. However, this incorporation depends on practically applicable, reliable and valid methods to register the impact of informal care. This paper presents the conceptualisation and a first test of the CarerQol instrument, aimed at(More)
Discounting costs and health benefits in cost-effectiveness analysis has been the subject of recent debate - some authors suggesting a common rate for both and others suggesting a lower rate for health. We show how these views turn on key judgments of fact and value: on whether the social objective is to maximise discounted health outcomes or the present(More)
Informal care makes up a significant part of the total amount of care provided to care recipients with chronic and terminal diseases. Still, informal care is often neglected in economic evaluations of health care programs. Probably this is related to the fact that the costs of informal care are to an important extent related to time inputs by relatives and(More)
An important subject of debate in cost-utility analysis of health care programmes is whether to include costs of unrelated medical care in life years gained. The inclusion of such costs is likely to be of consequence in the case of primary prevention. This paper presents different strategies regarding the inclusion not only of the costs, but also of the(More)
This paper comments on the recently published guidelines of the Washington Panel on incorporation of indirect non-medical costs, or productivity costs, in economic evaluations of health care. Traditionally the human capital or more recently the friction cost method is used to measure these costs. The Panel, however, recommends incorporating productivity(More)
Productivity losses without absence are scarcely discussed in the literature. In this paper, the construct validity of three different measurement instruments for productivity losses without absence is investigated. The data were collected under employees of a Dutch trade firm, not in specific patient groups. On an average day, over 7% of the respondents(More)
