Cross-utility Analysis: From 1 Different Sources
A form of cost-effectiveness analysis of alternative interventions in which costs are measured in monetary units and outcomes are measured in terms of their utility, usually to the individual, e.g. using QALYs.
A statistical procedure to combine results from different studies on a similar topic. The combination of results from multiple studies may produce a stronger conclusion than can be provided by any singular study. Meta-analysis is generally most appropriate when there are no definitive studies on a topic and non-definitive studies are in some disagreement.... meta-analysis
Analysis means a separation into component parts by determination of the chemical constituents of a substance. The process of analysis is carried out by various means, for example: chromatographic analysis by means of the adsorption column; colorimetric analysis by means of various colour tests; densimetric analysis by estimation of the speci?c gravity; gasometric analysis by estimation of the di?erent gases given o? in some process; polariscope analysis by means of the polariscope; and volumetric analysis by measuring volumes of liquids. Analysis is also sometimes used as an abbreviation for PSYCHOANALYSIS.... analysis
The systematic comparison, in monetary terms, of all the costs and benefits of proposed alternative schemes with a view to determining: which scheme or combination of schemes will contribute most to the achievement of predetermined objectives at a fixed level of investment; or the magnitude of the benefit that can result from schemes requiring the minimum investment. The resources required per unit of benefit must be determined, account being taken of the fact that costs and benefits accrue with time. For example, the cost of establishing a home and community care programme might be compared with the total cost of building residential facilities. Cost-benefit analysis can also be applied to specific medical tests and treatments.... cost-benefit analysis
A study that measures the prevalence of health outcomes or determinants of health, or both and other variables of interest in a population at a point in time or over a short period.... cross-sectional study
A set of techniques used when the variation in several variables has to be studied simultaneously. In statistics, any analytic method that allows the simultaneous study of two or more independent variables.... multivariate analysis
The process of analysing and comparing, on a single scale, the expected positive (benefits) and negative (risks, costs) results of an action, or lack of an action.... risk-benefit analysis
A systematic analysis of the content rather than the structure of a communication, such as a written work, speech or film, including the study of thematic and symbolic elements to determine the objective or meaning of the communication.... content analysis
A determination of the least costly among alternative interventions that are assumed to produce equivalent outcomes.... cost minimization analysis
A form of analysis that seeks to determine the costs and effectiveness of a health intervention compared with similar alternative interventions to determine the relative degree to which they will obtain the desired health outcome(s).... cost-effectiveness analysis
A determination of the economic impact of a disease or health condition, including treatment costs.... cost-of-illness analysis
An approach to decision-making that involves modelling the sequences or pathways of multiple possible strategies (e.g. of diagnosis and treatment for a particular clinical problem) to determine which is optimal. It is based upon available estimates (drawn from the literature or from experts) of the probabilities that certain events and outcomes will occur and the values of the outcomes that would result from each strategy.... decision analysis
A school of ‘analytical psychology’, ?rst described by Carl Gustav Jung in 1913. It introduced the concepts of ‘introvert’ and ‘extrovert’ personalities, and developed the theory of the ‘collective unconscious’ with its archetypes of man’s basic psychic nature. In contrast with Freudian analysis (see FREUDIAN THEORY), in Jungian analysis the relationship between therapist and patient is less one-sided because the therapist is more willing to be active and to reveal information about him or herself. (See also PSYCHOANALYSIS.)... jungian analysis
Review and analysis of practice profiles to identify and assess patterns of health care services.... profile analysis or profiling
See FIRST AID.... red cross
A tool to estimate the relationships among a dependent variable Y and one (or many) independent variable(s) X. The purpose of regression analysis is to find the “best fit” data points from a straight line drawn on an XY graph.... regression analysis
A process for identifying the basic or causal factor(s) that underlie variations in performance, including the occurrence or possible occurrence of an error.... root-cause analysis
This type of analysis utilizes existing data sources either through synthesis or integration; meta-analysis is an example of secondary data analysis.... secondary data analysis
The unit to which a performance measure is applied (e.g. subjects, patients, clinicians, group of professionals).... unit (of analysis)
The relative desirability or preference (usually from the perspective of the patient/client) for a specific health outcome or level of health status.... utility
Hair is believed to be a “time capsule” of a person’s metabolic activity. Believed to be a useful means of acquiring information regarding the concentration of mineral nutrients and toxins. Alone, it does not provide sufficient evidence for purposes of diagnosis, but helpful in building a picture of the nutritional state of the patient. ... hair analysis
Determination of the identity of a substance or of the individual chemical constituents of a mixture. Analysis may be qualitative, as in determining whether a particular substance is present, or it may be quantitative, that is, measuring the amount or concentration of one or more constituents. (See also assay.)... analysis, chemical
See psychoanalysis.... analysis, psychological
A type of strabismus (squint) in which one or both eyes turns inwards relative to the other.... cross-eye
n. see transvestism.... cross-dressing
see intervention study.... cross-over trial
any technique that produces an image in the form of a section through the body with the structures cut across. The main techniques are *ultrasonography, *computerized tomography, *magnetic resonance imaging, and some *nuclear medicine techniques (see positron emission tomography; SPECT scanning). If a series of thin-section images is stacked they can be ‘cut’ through to show other planes or allow reconstruction of three-dimensional images.... cross-sectional imaging
a research process in which results are reported according to the treatment arm to which a research subject was assigned, rather than the treatment eventually received. Intention to treat analysis is very widely used in clinical research as a method of avoiding *bias resulting from nonrandom withdrawal from the trial or crossover between treatment arms.... intention to treat analysis
a technique for identifying a specific form of messenger RNA in cells. It uses a gene *probe known to match the RNA being sought. Compare Southern blot analysis; Western blot analysis.... northern blot analysis
analysis of a specimen of semen, which should be obtained after five days of abstinence from coitus, in order to assess male fertility. Normal values are as follows: volume of ejaculate: 2–6.5 ml; liquefaction complete in 30 minutes; sperm concentration: 20–200 million spermatozoa per ml (sperm count refers to the total number of spermatozoa in the ejaculate); motility: 60% moving progressively at 30 minutes to 3 hours; abnormal forms: less than 20%. Analysis of three separate specimens is necessary before confirming the presence of an abnormal result.... seminal analysis
a framework for exploring how care is delivered, based on the idea that there are six main styles of interaction (prescriptive, informative, confronting, cathartic, catalytic, and supportive). The analysis is widely used to help health-care professionals develop an understanding of interpersonal relationships, reflect on their own practice, and enhance their interactions with clients.... six-category intervention analysis
a technique for identifying a specific form of DNA in cells. The DNA is extracted from the cells and restriction enzymes used to cut it into small fragments. The fragments are separated and a gene *probe known to match the DNA fragment being sought is used. Compare Northern blot analysis; Western blot analysis. [E. M. Southern (1938– ), US biologist]... southern blot analysis
a technique for the detection of specific proteins. After separation by *electrophoresis, the proteins are bound to radioactively labelled antibodies and identified by X-ray. Compare Northern blot analysis; Southern blot analysis.... western blot analysis
