Hospital emergency codes are coded messages often announced over a

of a hospital to alert staff to various classes of on-site emergencies. The use of codes is intended to convey essential information quickly and with minimal misunderstanding to staff while preventing stress and panic among visitors to the hospital. Such codes are sometimes posted on placards throughout the hospital or are printed on employee identification badges for ready reference. Hospital emergency codes have varied widely by location, even between hospitals in the same community. Confusion over these codes has led to the proposal for and sometimes adoption of standardized codes. In many American, Canadian, New Zealand and Australian hospitals, for example "code blue" indicates a patient has entered

, while "code red" indicates that a fire has broken out somewhere in the hospital facility. In order for a code call to be useful in activating the response of specific hospital personnel to a given situation, it is usually accompanied by a specific location description (e.g., "Code red, second floor, corridor three, room two-twelve"). Other codes, however, only signal hospital staff generally to prepare for the consequences of some external event such as a natural disaster.

United Kingdom

In the UK, hospitals have standardised codes across individual

trusts (England and Wales) and health boards (Scotland), but there are not many standardised codes across the entire NHS. This allows for differences in demands on hospitals in different areas, and also for hospitals of different roles to communicate different alerts according to their needs (e.g., a major trauma centre like St. George's Hospital in South London has different priority alert needs to a rural

A code black is declared by the hospital's general bed manager, who then relays this to the local ambulance service and posts updates for local healthcare services such as

teams. * Code red: This is the United Kingdom's rapid response code. This call gets specialist doctors and trauma teams to the location for assistance in things like major traumas and deteriorating patients in situations like choking or airway compromise. This call also can be used to activate a major hemorrhage protocol in the event of a massive bleed. This call is referred to as code red, staff assist, trauma protocol or rapid response. This is the only emergency protocol which has a code. The only other is what is announced as a mass casualty protocol not any codes. This is to show a major incident has taken place like a terrorist attack and the protocol is activated to alert specialists and begin special emergency procedures like mass casualty triage and decontamination. * Major haemorrhage protocol – activated via the code red system. A peri-arrest call is put out, but the transfusion lab is also alerted. A specified number of units of O-negative

will be continually sent until the major haemorrhage protocol is stood down. Otherwise, non-colour codes are mostly used across the NHS: * 2222 (crash call or peri-arrest call) – dialling 2222 from any internal phone in nearly all NHS hospitals will connect the caller immediately to the switchboard. The caller can then specify the type of cardiac arrest or peri-arrest call (usually adult, paediatric (or neo-natal) or obstetric) and give a location (eg "Adult cardiac arrest, Surgical Admissions Unit, ground floor B block" or "Obstetric peri-arrest, obstetric theatres, 4th floor maternity wing") and the switchboard will bleep the members of the relevant cardiac arrest or peri-arrest team. Some UK hospitals do not have a peri-arrest team, and the cardiac arrest team can be used for urgent medical emergencies where cardiac arrest is imminent. * 3333 (security alert) * 4444 (fire alert) * 'Fast bleep' codes – a 2222 call for a specific member of staff. For example, in

United States

In 2000, the Hospital Association of Southern California (HASC) determined that a uniform code system was needed after three people were killed in a shooting incident at a hospital after the wrong emergency code was called. While codes for fire (red) and medical emergency (blue) were similar in 90% of California hospitals queried, 47 different codes were used for infant abduction and 61 for combative person. In light of this, the HASC published a handbook titled ''Healthcare Facility Emergency Codes: A Guide for Code Standardization'' listing various codes and has strongly urged hospitals to voluntarily implement the revised codes. In 2003,
Maryland Maryland ( ) is a state in the Mid-Atlantic region of the United States. It shares borders with Virginia, West Virginia, and the District of Columbia to its south and west; Pennsylvania to its north; and Delaware and the Atlantic Ocean to ...
mandated that all acute hospitals in the state have uniform codes. In 2008, the Oregon Association of Hospitals & Health Systems, Oregon Patient Safety Commission, and Washington State Hospital Association formed a taskforce to standardize emergency code calls. After both states had conducted a survey of all hospital members, the taskforce found many hospitals used the same code for fire (code red); however, there were tremendous variations for codes representing respiratory and cardiac arrest, infant and child abduction, and combative persons. After deliberations and decisions, the taskforce suggested the following as the Hospital Emergency Code: *

* Code Clear: announced when emergency is over * Code Gray: combative person (combative or abusive behavior by patients, families, visitors, staff or physicians); if a weapon is involved code silver should be called * Code Green: emergency activation. * Code Orange: hazardous spills (a hazardous material spill or release; unsafe exposure to spill) * Code Pink: infant abduction, pediatric emergency and/or obstetrical emergency * Code Red: fire (also someone smoking in facility) (alternative: massive postpartum hemorrhage) * Code Silver: weapon or hostage situation * Code White: neonatal emergency, aggressive person or evacuation dependent on hospital. In some hospitals, an aggressive person is called as a Code Violet. * External triage: external disaster (external emergencies impacting hospital including: mass casualties; severe weather; massive power outages; and nuclear, biological, and chemical incidents) * Internal triage: internal emergency (internal emergency in multiple departments including: bomb or bomb threat; computer network down; major plumbing problems; and power or telephone outage.) * Rapid response team: medical team needed at bedside (a patient’s medical condition is declining and needs an emergency medical team at the bedside) prior to heart or respiration stopping


Plain Language Emergency Alerts

In 2015, the South Carolina Hospital Association formed a work group to develop plain language standardization code recommendations. Abolishing all color codes was suggested. In 2016, the Texas Hospital Association encouraged the use of standardized plain language emergency alerts at all Texas hospitals. The only color code that was still recommended was "code blue," meaning a cardiac arrest. Plain language alerts are announced using the following format: "Alert Type + Description + Location (general to specific) + Instructions (if applicable)." For example, if a patient in ICU Bed 4 went into cardiac arrest, the alert would be "Medical Alert + Code Blue + Second Floor + Intensive Care Unit + Bed 4."

Variations

"Plan blue" was used at St. Vincent's Hospital in New York City to indicate arrival of a trauma patient so critically injured that even the short delay of a stop in the ER for evaluation could be fatal; "plan blue" was called out to alert the surgeon on call to go immediately to the ER entrance and take the patient for immediate surgery.


"Doctor" codes

"Doctor" codes are often used in hospital settings for announcements over a general loudspeaker or paging system that might cause panic or endanger a patient's privacy. Most often, "doctor" codes take the form of "Paging Dr. Sinclair", where the doctor's "name" is a code word for a dangerous situation or a patient in crisis, e.g.: "Paging Dr. Firestone, third floor," to indicate a possible fire on the floor specified.
