The International Classification of Diseases (ICD) is a globally used medical classification used in epidemiology, health management and for clinical purposes. The ICD is maintained by the World Health Organization (WHO), which is the directing and coordinating authority for health within the United Nations System . [ 1 ]
Practitioners can come from several different educational streams: many begin as registered nurses, some as public health inspectors (environmental health officers), some as medical technologists (particularly in clinical microbiology), and some as physicians (typically infectious disease specialists). Specialized training in infection control ...
Types of coding systems specific to health care include: Diagnostic codes. Are used to determine diseases, disorders, and symptoms; Can be used to measure morbidity and mortality; Examples: ICD-9-CM, ICD-10, ICD-11 [1] Procedural codes. They are numbers or alphanumeric codes used to identify specific health interventions taken by medical ...
Marc Jamoulle divided medical situations into four quadrants based on if the patient was experiencing illness (i.e. if the patient experienced subjective poor health) and if the doctor had identified disease (constructed based on diagnostic criteria), with a different type of prevention happening in each:
The group exposed to treatment (left) has the risk of an adverse outcome (black) reduced by 50% (RRR = 0.5) compared to the unexposed group (right). In epidemiology , the relative risk reduction (RRR) or efficacy is the relative decrease in the risk of an adverse event in the exposed group compared to an unexposed group.
The relative risk reduction is 0.5 (50%), while the absolute risk reduction is 0.0001 (0.01%). The absolute risk reduction reflects the low probability of getting colon cancer in the first place, while reporting only relative risk reduction, would run into risk of readers exaggerating the effectiveness of the drug.

Research on preventive care addresses the question of whether it is cost saving or cost effective and whether there is an economics evidence base for health promotion and disease prevention. The need for and interest in preventive care is driven by the imperative to reduce health care costs while improving quality of care and the patient ...
