- Medical alarm
A medical alarm 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.
Typical systems have a wireless pendant or transmitter that can be activated in an emergency. 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.
Home alert systems were conceived and developed in Germany in the early 1970s by Wilhelm Hormann with the aim of developing new comprehensive structures for ambulatory and non-ambulatory care for the sick, the elderly, those who live alone, and disabled persons.
Hormann's concept of "home alert" (Hausnotruf) is thus to be seen as fairly broad, including the communication of biomedical data and social communication, and not limited to use as an "elder alarm". This has been set forth extensively in the research literature on PERS.
The technical implementation succeeded with the help of AEG-Telefunken Backnang GmbH and 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.
Types of providers
There are three different types of medical alarm providers:
- Hospital programs which are operated by volunteers. i.e. Philips Lifeline
- Mail out companies that claim installations are easy. i.e. Senior Safety
- Full service companies that provide installation, ongoing education and periodic testing programs. i.e. Automated Security Alert
A medical alarm system consists of
- an emergency transmitter, which is worn like a wristwatch or a pendant
- a base station, which is connected to the telephone and contains a very sensitive microphone/speaker unit.
In addition there are various other types of accessories (fall sensors, smoke detectors, motion detectors). A plethora of devices is available that can be connected over analog or digital ISDN connections. These devices make possible a high degree of safety, since in event of a power outage they operate on batteries.
In case of emergency, for example, after a fall or a suddenly appearing ailment, the user can set off a call for help by a simple press of the alert button on his wrist, without needing to reach the telephone. The devices are configured so that any calls or connections in progress are terminated and 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.
Through the microphone/speaker unit in the base station the employee of the alert system operator can speak with the user 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.
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 the base station 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 is not only intended for emergency use, but is also used to conveniently call for help with shopping or cleaning.
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.
Be sure to ask your medical alarm provider if they use a burglar alarm or security monitoring center for the monitoring of their medical alarms. Unfortunately many companies in the burglar alarm industry identified a financial opportunity by adding the monitoring of medical alarms to their monitoring centers. The problem is when a burglar alarm monitoring center receives a signal they are trained to get off the call immediately and they are more concerned about protecting property and assets than personal safety. A true Life Safety Monitoring Center will have individuals trained in Life Safety Monitoring. i.e. The operators are trained to deal with people, get them the necessary help, sometimes appease them and or just listen to the person. A Life Safety Monitoring Center spends as much time as needed with an individual and people are the only ones being monitored. Automated Security Alert and Philips Lifeline offer true Life Safety Monitoring.
Current and future trends
As technology evolves, the medical alarm systems have become much more sophisticated and an alert can be sent directly to a caregiver or family member's cell phone as a text message. The message is activated when the individual wearing the device falls or presses a button to call for help. In addition, some manufacturers have began releasing versions of the medical alert systems to the iPhone. These changes greatly simplify the installation and reduce cost of hardware required to set up these systems.
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. The system is designed to monitor the users location, position, and movement in the event a fall occurs.
PERS, a commonly accepted abbreviation for Personal Emergency Response System have been sold throughout the marketplace for more than forty years. The emerging technology surrounding these aging in place solutions has been coined “PERS 2.0”. Recognized at the national Healthcare Unbound conference in 2010, three PERS 2.0 solution providers appeared on the Aging Services panel, including Halo Monitoring, Jewish Home Lifecare, Philips Home Healthcare Solutions and Wellcore Corporation.
PERS systems and service models, which originally were designed to help the elderly summon emergency services when needed, are rapidly evolving. Aimed at presenting the latest evolution that PERS systems have available in today’s marketplace the sessions held during HealthCare Unbound presented the latest evolutions that PERS systems have undergone, presented examples of advanced PERS systems that have overcome some of the drawbacks of conventional PERS systems, the convergence between PERS (Safety), Wellness and Health monitoring systems as well as Social Connectedness technologies.
Some of the benefits offered within the PERS 2.0 market versus a traditional medical alarm include:
- Automatic Fall Detection. Fall detection without the need of a “panic button” which is often inaccessible when unconscious.
- User Compliance Tracking. Detection when the device is not worn – alerting caregivers of the heightened risk or to provide gentle reminders to seniors that wish to wear, but forget.
- Caregiver Notifications. Adult children and other authorized caregivers can receive notifications with text and email messages to alert loved ones if the user is ok.
- Private caregiving websites are created for each user to monitor vital signs and activity levels
Traditional or legacy PERS offer benefits to independently living seniors and can save money. PERS 2.0 products offer everything legacy PERS offer but adds new benefits at a similar price making these products extremely popular within the senior market.
Medical alarms in pop culture
"I've fallen and I can't get up!" was a catchphrase of the late 1980s based on a line from a United States based television commercial. In this commercial an elderly actor is seen fallen and distraught and uses the medical alert system to summon help. The unexpected humour in the commercial made it a universal punchline for many comedic acts.
