Medical alarm

Last updated

A medical alarm [1] is an alarm system designed to signal the presence of a hazard requiring urgent attention and to summon emergency medical personnel. Other terms for a medical alarm are Personal Emergency Response System (PERS) or medical alert. It is especially important to recognize the need to respond to situations where the person is unable to summon help. [2]

Contents

Typical systems have a wireless pendant or transmitter that can be activated in an emergency. [3] When the medical alarm is activated, the signal is transmitted to an alarm monitoring company's central station, other emergency agency or other programmed phone numbers. Medical personnel are then dispatched to the site where the alarm was activated. Elderly people and disabled people who live alone commonly use/require medical alarms, and some of them have been victimized by fraudulent marketing. [4]

Origin

The concept of home alert systems was conceived and developed in the 1970s. The American implementation was conceived in 1973 by Andrew Dibner, "a psychologist on leave from Boston University who was studying personality in advanced age." [5] In Germany, in the early 1970s, Wilhelm Hormann thought about developing a comprehensive structure for ambulatory and non-ambulatory care for the sick, the elderly, those who live alone, and people with disabilities.[ citation needed ]

Dibner [6] established a company in 1974. Named Lifeline Systems Inc., it manufactured all its own equipment, and by 1984 had 225 employees and served "some 42,000 people in 48 states." [5] In 1975 American International Telephone Company offered an emergency home phone system. The user wore a medallion around the neck that when pushed delivered a preprogrammed message to several phone numbers. [7]

Hormann's concept of "home alert" (Hausnotruf) with help from AEG-Telefunken Backnang GmbH was presented to the international public early in 1980. In 1982 the Hausnotruf PERS system was distinguished with the Frankfurt Innovation Prize of the German Economy by the Wirtschaftsclub Rhein Main e.V. (Rhein-Main Business Club) in Frankfurt-am-Main.[ citation needed ]

A 2012 Swiss estimate reported that around 50,000 emergency call devices were then use. [8]

Types of providers

There are several different types of medical alarm providers:

Types of devices

There are a number of different devices that can be used to trigger an alarm.

Active devices require the user to take some action to trigger an alarm condition; passive systems monitor the user and raise an alarm based on an algorithm - a fall, lack of activity, etc. A weakness of active devices is that the user must be conscious to trigger the alarm. Both passive and active devices require that the user wear the device. Installed systems can be expensive and difficult to deploy.

A medical alarm system may consist of

In addition there are various other types of accessories (emergency buttons, fall sensors, smoke detectors, carbon monoxide detectors, flood detectors, motion detectors) that can be placed around the home and integrated with the base station. Base stations can be connected over analog or digital ISDN connections. In the event of a power failure, these devices can operate on batteries, thus adding an extra degree of safety.

In case of emergency the user can set off a call for help by the press of an alert button on a personal device, without needing to reach the telephone. Systems with passive alerts may set off a call for help if no movement has been detected over some period of time, or if a fall is detected. If a base station shares a phone line, it is able to terminate an in-progress call so that a call for help can be initiated over the telephone.

With some systems, an alert arrives in the offices of the alert system operator (which may be a public rescue service or a private security company) and the data of the affected person (address, medical condition, family contacts) are displayed. With others, there is no system operator, and the user simply programs the numbers of family members, neighbors, or local emergency responders. If present, a responder can speak with the user through the microphone/speaker in order to clarify the type and severity of the emergency and discuss further measures.

Depending on the organization of the service and the type of emergency help required, relatives or neighbors can be informed. If necessary, health care services or personal physicians can be notified or emergency medical services can be alarmed. Some monitoring services also provide the client with a USB medical alert device so that arriving emergency personnel can have immediate access to vital medical information.

Some units can call user selected numbers, so relatives or neighbors can be called directly, avoiding the expense of a monitoring service. [13]

With some systems, it is common practice for the user to leave a house key with a neighbor or at the system office so that emergency personnel can enter the house even if the resident cannot open the door. Keys are kept in a safe and marked only with numbers so that improper use is precluded.

In addition to this "active alarm" there is also the option of a "passive alarm" (sometimes called a "safety clock"), on the principle of a so-called dead man's switch . On some device is a button that the user is to activate several times a day; this confirms that the user is well. If this confirmation goes lacking for a longer period (usually around 12 hours), a telephone call is placed or someone is sent to check whether everything is in order at the residence. Depending on the company offering it, the system may provide for more than emergency use. Some solutions will periodically call to converse with the user.

Monitoring

In the event of an alarm, some systems will place a phone call to a community emergency service such as 911. Others will place a call to the configured number of a friend or family member. Some systems will send an SMS message to configured contacts. [14]

Some systems provide 24x7x365 professional monitoring. The monitoring service for medical alarms (central station) is a call center facility that is staffed by trained professionals. These professionals are available at all times to receive calls from the medical alarm system. Monitoring service centers that are approved by Underwriters Laboratories (UL) have internal backup systems to add redundancy. Some monitoring services employ trained medical operators enabling them to better evaluate the severity of medical requests. In most less developed countries however, response to medical alarms are slow.

A Florida State University research team is currently working on an Android device to be worn by the user that not only can be used as a typical medical alert monitoring system but has fall detection software built into it. [15] The system is designed to monitor the user's location, position, and movement in the event a fall occurs. New fall detection technologies are being integrated into watches, pendants, hearing aids, and wall mounted devices that do not need to be worn by an individual. [16]

Fall sensing/fall detection

Detecting a fall can be from more than one point of view, covering both during and after the fall:

Costs

Aside from one time cost for hardware, there are often ongoing fees and sometimes per-activation charges. Some or all of these may be partially funded by reductions on insurance or by an annual prepayment when compared to paying monthly. [5]

Fraud

Federal and State charges have been brought against firms for various forms of fraud involving false promises, improper billing and violations of Do Not Call laws. [19] [20] [4] Operationally, those systems that malfunction and for which service is not done on a timely basis can result in other problems: "some localities will fine you if your system cries wolf." [18]

Medical alarms in pop culture

"I've fallen and I can't get up!" was a catchphrase from a 1989 LifeCall Medical Alert System television commercial. In this commercial, an elderly actor is seen fallen and distraught and uses the medical alert system to summon help. The unintentional humor in the commercial made it a frequent punchline for many comedic acts. Due to the trademark changing hands between competing companies, the trademark currently belongs to LifeCall's direct competitor, Life Alert Emergency Response, and is used in all channels of Life Alert's advertising.

A fire alarm control panel (FACP), fire alarm control unit (FACU), fire indicator panel (FIP), or simply fire alarm panel is the controlling component of a fire alarm system. The panel receives information from devices designed to detect and report fires, monitors their operational integrity, and provides for automatic control of equipment, and transmission of information necessary to prepare the facility for fire based on a predetermined sequence. The panel may also supply electrical energy to operate any associated initiating device, notification appliance, control, transmitter, or relay. There are four basic types of panels: coded panels, conventional panels, addressable panels, and multiplex systems.

Telecare is technology-based healthcare such as the monitoring of patient vital organs so that they may remain safe and independent in their own homes. Devices may include health and fitness apps, such as exercise tracking tools and digital medication reminder apps, or technologies that issue early warning and detection. The use of sensors may be part of a package which can provide support for people with illnesses such as dementia, or people at risk of falling.

A false alarm, also called a nuisance alarm, is the deceptive or erroneous report of an emergency, causing unnecessary panic and/or bringing resources to a place where they are not needed. False alarms may occur with residential burglary alarms, smoke detectors, industrial alarms, and in signal detection theory. False alarms have the potential to divert emergency responders away from legitimate emergencies, which could ultimately lead to loss of life. In some cases, repeated false alarms in a certain area may cause occupants to develop alarm fatigue and to start ignoring most alarms, knowing that each time it will probably be false. Intentionally falsely activating alarms in businesses and schools can lead to serious disciplinary actions, and criminal penalties such as fines and jail time.

An aspirating smoke detector (ASD) is a system used in active fire protection, consisting of a central detection unit which draws air through a network of pipes to detect smoke. The sampling chamber is based on a nephelometer that detects the presence of smoke particles suspended in air by detecting the light scattered by them in the chamber. ASDs can typically detect smoke before it is visible to the naked eye.

<span class="mw-page-title-main">Fire alarm system</span> A system, that works using multiple devices to warn of a fire or other types of emergencies

A fire alarm system is a building system designed to detect, alert occupants, and alert emergency forces of the presence of fire, smoke, carbon monoxide, or other fire-related emergencies. Fire alarm systems are required in most commercial buildings. They may include smoke detectors, heat detectors, and manual fire alarm activation devices. All components of a fire alarm system are connected to a fire alarm control panel. Fire alarm control panels are usually found in an electrical or panel room. Fire alarm systems generally use visual and audio signalization to warn the occupants of the building. Some fire alarm systems may also disable elevators, which are unsafe to use during a fire under most circumstances.

Life Alert Emergency Response, Inc. is a nationwide American company, with headquarters in Encino, California, which provides services that help elderly contact emergency services. The company was founded in 1987. The company's system consists of a main unit and a small wireless help button that is worn by the user at all times. Former Surgeon General C. Everett Koop appeared in commercials for Life Alert starting in 1992, stating that he used one. He remained a spokesman for the company until his death in 2013.

Home automation for the elderly and disabled focuses on making it possible for older adults and people with disabilities to remain at home, safe and comfortable. Home automation is becoming a viable option for older adults and people with disabilities who would prefer to stay in the comfort of their homes rather than move to a healthcare facility. This field uses much of the same technology and equipment as home automation for security, entertainment, and energy conservation but tailors it towards old people and people with disabilities.

A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals.

<span class="mw-page-title-main">I've fallen, and I can't get up!</span> Catchphrase

"I've fallen, and I can't get up!" is a catchphrase of the late 1980s and early 1990s popular culture based upon a line from a United States-based television commercial.

A Safety confirmation system is a way of determining each day whether someone who lives alone is safe. All the person has to do is to press, before a time agreed with him or her, an 'I am okay' button on a special landline or mobile phone handset that can also be used normally to make calls. The button-press is transmitted to a monitoring centre and managed automatically. A follow-up system is initiated if a user fails to confirm that they are okay. If the button is not pressed by the agreed time it can be taken as a passive request for contact.

Lifeline Systems, Inc. was founded in Boston, MA in 1974 by gerontologist Andrew S. Dibner and his wife, sociologist Susan S. Dibner.
