Early versions of healthcare-related quality of life measures referred to simple assessments of physical abilities by an external rater (for example, the patient is able to get up, eat and drink, and take care of personal hygiene without any help from others) or even to a single measurement (for example, the angle to which a limb could be flexed).
Quality of life (QOL) is defined by the World Health Organization as "an individual's perception of their position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations, standards and concerns".
Health care quality is the degree to which health care services for individuals and populations increase the likelihood of desired health outcomes. [2] Quality of care plays an important role in describing the iron triangle of health care relationships between quality, cost, and accessibility of health care within a community. [3]
- in self-care skills. Follow-up: mean 12 weeks: Life skills programmes make no difference to self-care when compared with standard care, but, at present it is not possible to be confident about the difference between these two treatments. This finding is based on data of very limited quality. RR 1 (0.28 to 3.54) Very low Leaving the study early
The Donabedian model is a conceptual model that provides a framework for examining health services and evaluating quality of health care. [1] According to the model, information about quality of care can be drawn from three categories: "structure", "process", and "outcomes". [2]
EQ-5D is a standardised measure of health-related quality of life developed by the EuroQol Group to provide a simple, generic questionnaire for use in clinical and economic appraisal and population health surveys. EQ-5D assesses health status in terms of five dimensions of health and is considered a ‘generic’ questionnaire because these ...
The quality-adjusted life year (QALY) is a generic measure of disease burden, including both the quality and the quantity of life lived. [ 1 ] [ 2 ] It is used in economic evaluation to assess the value of medical interventions. [ 1 ]
The quality of life gained is the product of life span and quality rating with the new treatment less the same calculation for the old treatment, i.e. (1.25 x 0.6) less (1.0 x 0.4) = 0.35 QALY. The marginal cost of the new treatment to deliver this extra gain is £7,000 so the cost per quality life year gained is £7000/0.35 or £20,000.
