External cause

Last updated

In medicine, an external cause is a reason for the existence of a medical condition which can be associated with a specific object or acute process that was caused by something outside the body. Such causes are classified as "E codes" in ICD 9. [1]

External Cause of Injury Codes (E codes) are ICD-9-CM codes or ICD-10 codes that are used to define the mechanism of death or injury, along with the place of occurrence of the event. E codes are assigned on death certificates based on the manner of death. ICD-10 codes in the range V01–X59 refer to unintentional injuries. Codes in the range X60–X84 refer to intentional self-harm. Codes in the range Y85–Y09 refer to assault, and codes in the range Y10–Y34 refer to events of undetermined intent. [2]

E codes are well-collected on death certificate data, but less so on hospital discharge data. Numerous initiatives have increased the percentage of records coded (CDC, MMWR March 28, 2008 / Vol. 57 / No. RR-1).

The International Classification of Diseases (ICD) is a globally used diagnostic tool for epidemiology, health management and 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. The ICD is originally designed as a health care classification system, providing a system of diagnostic codes for classifying diseases, including nuanced classifications of a wide variety of signs, symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or disease. This system is designed to map health conditions to corresponding generic categories together with specific variations, assigning for these a designated code, up to six characters long. Thus, major categories are designed to include a set of similar diseases.

Cardiac arrest Sudden stop in effective blood flow due to the failure of the heart to contract effectively

Cardiac arrest is a sudden loss of blood flow resulting from the failure of the heart to pump effectively. Signs include loss of consciousness and abnormal or absent breathing. Some individuals may experience chest pain, shortness of breath, or nausea before cardiac arrest. If not treated within minutes, it typically leads to death.

Nosology is the branch of medical science that deals with the classification of diseases. Fully classifying a medical condition requires knowing its cause, the effects it has on the body, the symptoms that are produced, and other factors. For example, influenza is classified as an infectious disease because it is caused by a virus, and it is classified as a respiratory infection because the virus infects and damages certain tissues in the respiratory tract. The more that is known about the disease, the more ways the disease can be classified nosologically.

Implantable cardioverter-defibrillator Device implantable inside the body, able to perform cardioversion, defibrillation, and (in modern versions) pacing of the heart

An implantable cardioverter-defibrillator (ICD) or automated implantable cardioverter defibrillator (AICD) is a device implantable inside the body, able to perform cardioversion, defibrillation, and pacing of the heart. The device is therefore capable of correcting most life-threatening cardiac arrhythmias. The ICD is the first-line treatment and prophylactic therapy for patients at risk for sudden cardiac death due to ventricular fibrillation and ventricular tachycardia. Current devices can be programmed to detect abnormal heart rhythms and deliver therapy via programmable antitachycardia pacing in addition to low-energy and high-energy shocks.

In law, medicine, and statistics, cause of death is an official determination of conditions resulting in a human's death, which may be recorded on a death certificate. A cause of death is determined by a medical examiner. The cause of death is a specific disease or injury, in contrast to the manner of death which is a small number of categories like "natural", "accident", "suicide", and "homicide", which have different legal implications.

Vital statistics is accumulated data gathered on live births, deaths, migration, fetal deaths, marriages and divorces. The most common way of collecting information on these events is through civil registration, an administrative system used by governments to record vital events which occur in their populations. Efforts to improve the quality of vital statistics will therefore be closely related to the development of civil registration systems in countries. Civil registration followed the practice of churches keeping such records since the 19th century.

A medical classification is used to transform descriptions of medical diagnoses or procedures into standardized statistical code in a process known as clinical coding. Diagnosis classifications list diagnosis codes, which are used to track diseases and other health conditions, inclusive of chronic diseases such as diabetes mellitus and heart disease, and infectious diseases such as norovirus, the flu, and athlete's foot. Procedure classifications list procedure code, which are used to capture interventional data. These diagnosis and procedure codes are used by health care providers, government health programs, private health insurance companies, workers' compensation carriers, software developers, and others for a variety of applications in medicine, public health and medical informatics, including:

In health care, diagnosis codes are used as a tool to group and identify diseases, disorders, symptoms, poisonings, adverse effects of drugs and chemicals, injuries and other reasons for patient encounters. Diagnostic coding is the translation of written descriptions of diseases, illnesses and injuries into codes from a particular classification. In medical classification, diagnosis codes are used as part of the clinical coding process alongside intervention codes. Both diagnosis and intervention codes are assigned by a health professional trained in medical classification such as a clinical coder or Health Information Manager.

SNOMED CT or SNOMED Clinical Terms is a systematically organized computer processable collection of medical terms providing codes, terms, synonyms and definitions used in clinical documentation and reporting. SNOMED CT is considered to be the most comprehensive, multilingual clinical healthcare terminology in the world. The primary purpose of SNOMED CT is to encode the meanings that are used in health information and to support the effective clinical recording of data with the aim of improving patient care. SNOMED CT provides the core general terminology for electronic health records. SNOMED CT comprehensive coverage includes: clinical findings, symptoms, diagnoses, procedures, body structures, organisms and other etiologies, substances, pharmaceuticals, devices and specimens.

Button cell

A watch battery or button cell is a small single cell battery shaped as a squat cylinder typically 5 to 25 mm in diameter and 1 to 6 mm high — resembling a button. Stainless steel usually forms the bottom body and positive terminal of the cell. An insulated top cap is the negative terminal.

The Mortality Medical Data System (MMDS) is used to automate the entry, classification, and retrieval of cause-of-death information reported on death certificates throughout the United States and in many other countries. The National Center for Health Statistics (NCHS) began the system's development in 1967.

A clinical coder – also known as clinical coding officer, diagnostic coder, medical coder, nosologist or medical records technician – is a health information professional whose main duties are to analyse clinical statements and assign standard codes using a classification system. The data produced are an integral part of health information management, and are used by local and national governments, private healthcare organizations and international agencies for various purposes, including medical and health services research, epidemiological studies, health resource allocation, case mix management, public health programming, medical billing, and public education.

ICD-10 is the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. Work on ICD-10 began in 1983, became endorsed by the Forty-third World Health Assembly in 1990, and was first used by member states in 1994. It will be replaced by ICD-11 on January 1, 2022.

History of chronic fatigue syndrome

The history of chronic fatigue syndrome is thought to date back to the 19th century and before.

The International Classification of External Causes of Injury (ICECI) is a medical classification providing codes for external injuries. It is designed to aid professionals and researchers in the statistical tracking and prevention of injury.

Healthcare Cost and Utilization Project

The Healthcare Cost and Utilization Project is a family of healthcare databases and related software tools and products from the United States that is developed through a Federal-State-Industry partnership and sponsored by the Agency for Healthcare Research and Quality (AHRQ).

The ICD-11 is the eleventh revision of the International Classification of Diseases. It will eventually replace the ICD-10 as the global standard for coding health information and causes of death. The ICD-11 is developed and regularly updated by the World Health Organization (WHO). Its development spanned over a decade of work, involving over 300 specialists from 55 countries divided into 30 work groups, with an additional 10,000 proposals from people all over the world. Following an alpha version in May 2011 and a beta draft in May 2012, a stable version of the ICD-11 was released on 18 June 2018, and officially endorsed by all WHO members during the 72nd World Health Assembly on 25 May 2019.

A hospital-acquired condition (HAC) is an undesirable situation or condition that affects a patient and that arose during a stay in a hospital or medical facility. It is a designation used by Medicare/Medicaid in the US for determining MS-DRG reimbursement beginning with version 26. Not only hospital-acquired infections but also any other situation or condition, such as pressure ulcers, blood type mismatch, or iatrogenic injury, can be a HAC.

In many legal jurisdictions, the manner of death is a determination, typically made by the coroner, medical examiner, police, or similar officials, and recorded as a vital statistic. Within the United States and the United Kingdom, a distinction is made between the cause of death, which is a specific disease or injury, versus manner of death, which is primarily a legal determination. Different categories are used in different jurisdictions, but manner of death determinations include everything from very broad categories like "natural" and "homicide" to specific manners like "traffic accident" or "gunshot wound". In some cases an autopsy is performed, either due to general legal requirements, because the medical cause of death is uncertain, upon the request of family members or guardians, or because the circumstances of death were suspicious.
