Epidemiologic Studies definition: Studies designed to examine associations, commonly, hypothesized causal relations. They are usually concerned with identifying or measuring the effects of risk factors or exposures. The common types of analytic study are CASE-CONTROL STUDIES; COHORT STUDIES; and CROSS-SECTIONAL STUDIES.
Epidemiology Research definition: The study of human populations to identify causes of disease and factors determining and influencing the frequency and distribution of disease, injury, and other health related events.
Blood Coagulation Tests definition: Laboratory tests for evaluating the individual's clotting mechanism.
blood coagulation test definition: laboratory tests for evaluating the individual's blood clotting mechanisms.
clinical research definition: research conducted with human subjects or on material of human origin in which an investigator directly interacts with human subjects; includes development of new technologies, mechanism of human diseases, therapy, clinical trials, epidemiology, behavior and health services research.
Clinical Study definition: Research conducted with human subjects or on material of human origin in which an investigator directly interacts with human subjects; includes development of new technologies, study of mechanisms of human diseases, therapy, clinical trials, epidemiologic, behavior, and health services research.
Cohort Studies definition: Studies in which subsets of a defined population are identified. These groups may or may not be exposed to factors hypothesized to influence the probability of the occurrence of a particular disease or other outcome. Cohorts are defined populations which, as a whole, are followed in an attempt to determine distinguishing subgroup characteristics.
COHORT ANALYTIC STUDY definition: Prospective investigation of the factors that might cause a disorder in which a cohort of individuals who do not have evidence of an outcome of interest but who are exposed to the putative cause are compared with a concurrent cohort who are also free of the outcome but not exposed to the putative cause. Both cohorts are then followed to compare the incidence of the outcome of interest.
Comparative Study definition: Comparison of outcomes, results, responses, etc for different techniques, therapeutic approaches or other inputs.
Evaluation Studies definition: Works consisting of studies determining the effectiveness or utility of processes, personnel, and equipment.
Feasibility Studies definition: Studies to determine the advantages or disadvantages, practicability, or capability of accomplishing a projected plan, study, or project.
Follow-Up Studies definition: Studies in which individuals or populations are followed to assess the outcome of exposures, procedures, or effects of a characteristic, e.g., occurrence of disease.
Follow-up Study definition: Study in which persons exposed to risk or given a designated preventive or therapeutic regimen are observed over a period or at intervals to determine the outcome of the exposure or regimen.
Intervention Studies definition: Epidemiologic investigations designed to test a hypothesized cause-effect relation by modifying the supposed causal factor(s) in the study population.
Longitudinal Studies definition: Studies in which variables relating to an individual or group of individuals are assessed over a period of time.
prospective definition: In medicine, a study or clinical trial in which participants are identified and then followed forward in time.
longitudinal study definition: Investigation in which data are collected from a number of subjects over a long period of time (a well-known example is the Framingham Study).
Pilot Projects definition: Small-scale tests of methods and procedures to be used on a larger scale if the pilot study demonstrates that these methods and procedures can work.
pilot study definition: The initial study examining a new method or treatment.
Prospective Studies definition: Observation of a population for a sufficient number of persons over a sufficient number of years to generate incidence or mortality rates subsequent to the selection of the study group.
Retrospective Studies definition: Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
Sampling Studies definition: Studies in which a number of subjects are selected from all subjects in a defined population. Conclusions based on sample results may be attributed only to the population sampled.
Serologic Tests definition: Diagnostic procedures involving immunoglobulin reactions.
Seroepidemiologic Studies definition: EPIDEMIOLOGIC STUDIES based on the detection through serological testing of characteristic change in the serum level of specific ANTIBODIES. Latent subclinical infections and carrier states can thus be detected in addition to clinically overt cases.
Social Sciences definition: Disciplines concerned with the interrelationships of individuals in a social environment including social organizations and institutions. Includes Sociology and Anthropology.
Social Sciences definition: Comprises the scientific study of the human aspects of the world. They are also known as social studies. Psychology studies the human mind, sociology examines human society, political science studies the governing of groups and economics concerns itself with the allocation of wealth in society.
case report definition: A detailed report of the diagnosis, treatment, and follow-up of an individual patient. Case reports also contain some demographic information about the patient (for example, age, gender, ethnic origin).
Case Study definition: An uncontrolled observational study containing a detailed report of the diagnosis, treatment, and follow-up of an individual patient. Case reports also contain some demographic information about the patient (for example, age, gender, ethnic origin).
diagnostic test definition: heading term for tests not treed elsewhere under DIAGNOSIS.
CROSSOVER TRIAL definition: A method of comparing two or more treatments or interventions in which subjects or patients, upon completion of the course of one treatment, are switched to another. Typically, allocation to the first treatment is by random process. Participants' performance in one period is used to judge their performance in others, usually reducing variability.
Cross-Over Studies definition: Studies comparing two or more treatments or interventions in which the subjects or patients, upon completion of the course of one treatment, are switched to another. In the case of two treatments, A and B, half the subjects are randomly allocated to receive these in the order A, B and half to receive them in the order B, A. A criticism of this design is that effects of the first treatment may carry over into the period when the second is given. (Last, A Dictionary of Epidemiology, 2d ed)
Chemical method definition: Chemical
Interdisciplinary Research definition: Studies that bring together multiple scientific disciplines to address specific issues.
laboratory study definition: Research done in a laboratory. These studies may use test tubes or animals to find out if a drug, procedure, or treatment is likely to be useful. Laboratory studies take place before any testing is done in humans.
Multicenter Study definition: Work consisting of a controlled study executed by several cooperating institutions.
multicenter trial definition: Clinical trial conducted according to a single protocol but at more than one site, and, therefore, carried out by more than one investigator. [ICH E9 Glossary]
Psychosocial Care definition: Study of psychological and social factors.
preclinical study definition: Research using animals to find out if a drug, procedure, or treatment is likely to be useful. Preclinical studies take place before any testing in humans is done.
Preclinical Study definition: A study to test a drug, procedure or other medical treatment in animals. The aim is to collect data in support of safety. Preclinical studies are required before clinical trials can be started.
preclinical studies definition: Animal studies that support Phase 1 safety and tolerance studies and must comply with good laboratory practice (GLP). NOTE: Data about a drug's activities and effects in animals help establish boundaries for safe use of the drug in subsequent human testing (clinical studies or trials).
Genome-Wide Association Study definition: An analysis comparing the allele frequencies of all available (or a whole GENOME representative set of) polymorphic markers in unrelated patients with a specific symptom or disease condition, and those of healthy controls to identify markers associated with a specific disease or condition.
