Classification
British Hypertension Society Classification of Blood Pressure Levels (BHS-IV)
This classification equates with that of the European Society of Hypertension (ESH) and that of World Health Organization/ International Society of Hypertension (WHO/ISH), and is based on clinic blood pressure values. If systolic blood pressure and diastolic blood pressure fall into different categories, the higher value should be taken for classification.
NYHA Functional Classification for Congestive Heart Failure
The New York Heart Association (NYHA) Functional Classification provides a simple way of classifying heart disease (originally cardiac failure), useful for preoperative assessment. It places patients in one of four categories, based on how much they are limited during physical activity:

Wagner and the University of Texas Wound Classification Systems of Diabetic Foot Ulcers
The well-established widely used Wagner wound classification system and the new University of Texas (UT) diabetic wound classification system both provide descriptions of ulcers to varying degrees. Both wound classification systems are easy to use among health care providers, and both can provide a guide to planning treatment strategies.
1990 Criteria of ACR for the Classification of Fibromyalgia
Fibromyalgia syndrome (FMS) is conceptualized as a chronic disorder characterized by widespread and persistent non-inflammatory musculoskeletal pain. Concomitant symptoms usually include fatigue, insomnia, morning stiffness, depression, anxiety, and cognitive problems (forgetfulness, concentration difficulties, mental slowness, memory and attention problems, etc.). Furthermore, the majority of FMS patients usually show predominantly negative affect, including neuroticism, alexithymia, and catastrophizing and impaired health-related quality of life.
Classification of Fever of Unknown Origin (FUO)
FUO is body temperature ≥ 38.3° C (101° F) rectally that does not result from transient and self-limited illness, rapidly fatal illness, or disorders with clear-cut localizing symptoms or signs or with abnormalities on common tests such as chest x-ray, urinalysis, or blood cultures.
ACR Criteria for the Classification of Churg-Strauss Syndrome (CSS)
American College of Rheumatology 1990 criteria for the classification of Churg-Strauss syndrome (CSS). Classified as CSS if at least four of six criteria are present
ATP III Classification of LDL, Total, HDL Cholesterol and Triglycerides
ATP III Classification of LDL, Total, HDL Cholesterol and Triglycerides (mg/dL)
GINA Classification of Asthma Severity
The Global Initiative for Asthma (GINA) works with health care professionals and public health officials around the world to reduce asthma prevalence, morbidity, and mortality. The gold standard in classifying severity of asthma is the GINA classification.
