A hospital bed or hospital cot is a bed specially designed for hospitalized patients or others in need of some form of health care. These beds have special features both for the comfort and well-being of the patient and for the convenience of health care workers. Common features include adjustable height for the entire bed, the head, and the feet, adjustable side rails, and electronic buttons to operate both the bed and other nearby electronic devices.

Hospital beds and other similar types of beds such as nursing care beds are used not only in hospitals, but in other health care facilities and settings, such as nursing homes, assisted living facilities, outpatient clinics, and in home health care.

While the term "hospital bed" can refer to the actual bed, the term "bed" is also used to describe the amount of space in a health care facility, as the capacity for the number of patients at the facility is measured in available "beds."

There are various pros and cons for the different types of hospital beds, depending on the functions and features available, among other factors. [2]

History

[

edit

]

Beds with adjustable side rails first appeared in Britain some time between 1815 and 1825.[3]

In 1874 the mattress company Andrew Wuest and Son, Cincinnati, Ohio, registered a patent for a type of mattress frame with a hinged head that could be elevated, a predecessor of the modern day hospital bed.[4]

The modern 3-segment adjustable hospital bed was invented by Willis Dew Gatch, chair of the Department of Surgery at the Indiana University School of Medicine, in the early 20th century. This type of bed is sometimes referred to as the Gatch Bed.[3]

The modern push-button hospital bed was invented in 1945, and it originally included a built-in toilet in hopes of eliminating the bedpan.[5]

Modern features

Alternating pressure mattress

[

edit

Alternating pressure mattresses use computer-controlled pumps to inflate and deflate automatically in order to lower the risk of bed sores.[6]

Bed exit alarm

[

edit

]

Many modern hospital beds are able to feature a bed exit alarm whereby a pressure pad on or in the mattress arms an audible alert when a weight such as a patient is placed on it, and activating the full alarm once this weight is removed. This is helpful to hospital staff or caregivers monitoring any number of patients from a distance (such as a nurse's station) as the alarm will trigger in the event of a patient (especially the elderly or memory impaired) falling out of the bed or wandering off unsupervised. This alarm can be emitted solely from the bed itself or connected to the nurse call bell/light or hospital phone/paging system.[7] Also some beds can feature a multi-zone bed exit alarm which can alert the staff when the patient start moving in the bed and before the actual exit which is necessary for some cases.

CPR function

[

edit

]

In the event of the bed occupant suddenly requiring cardiopulmonary resuscitation, some hospital beds offer a CPR function in the form of a button or lever which when activated flattens the bed platform and put it in lowest height and deflates and flattens the bed's air mattress (if installed) creating a flat hard surface necessary for CPR administration.[8]

Elevation

[

edit

]

Beds can be raised and lowered at the head, feet, and their entire height. While on older beds this is done with cranks usually found at the foot of the bed, on modern beds this feature is electronic.

Today, while a fully electric bed has many features that are electronic, a semi-electric bed has two motors, one to raise the head, and the other to raise the foot.[9]

Raising the head (known as a Fowler's position) can provide some benefits to the patient, the staff, or both. The Fowler's position is used for sitting the patient upright for feeding or certain other activities, or in some patients, can ease breathing, or may be beneficial to the patient for other reasons.[9]

Raising the feet can help ease movement of the patient toward the headboard and may also be necessary for certain conditions.

Raising and lowering the height of the bed can help bring the bed to a comfortable level for the patient to get in and out of bed, or for caregivers to work with the patient.

There are 5 function beds which comes with many functions such as head elevation, foot elevation, Trendelenburg, reverse Trendelenburg positions with height adjustment options.[10] These type of beds are typically used in ICUs and for patients who are high dependent.

Side rails

[

edit

]

Beds have side rails that can be raised or lowered. These rails, which serve as protection for the patient and sometimes can make the patient feel more secure, can also include the buttons used for their operation by staff and patients to move the bed, call the nurse, or even control the television.[11]

There are many types of side rails to serve different purposes. While some are simply to prevent patient falls, others have equipment that can aid the patient themself without physically confining the patient to bed.

Side rails, if not built properly, can be of risk for patient entrapment. In the United States, more than 300 deaths were reported as a result of this between 1985 and 2004.[12] As a result, the Food and Drug Administration has set guidelines regarding the safety of side rails.[13]

In some cases, use of the rails may require a physician's order (depending on local laws and the policies of the facility where they are used) as rails may be considered a form of medical restraint.

Specialist beds

[

edit

]

Many specialist hospital beds are also produced to effectively treat different injuries. These include standing beds, turning beds and legacy beds. These are usually used to treat back and spinal injuries as well as severe trauma.

Tilting

[

edit

]

Some advanced beds are equipped with columns which help tilt the bed to 15-30 degrees on each side. Such tilting can help prevent pressure ulcers for the patient, and help caregivers to do their daily tasks with less of a risk of back injuries.[14]

Wheels

[

edit

]

Wheels enable easy movement of the bed, either within parts of the facility in which they are located, or within the room. Sometimes movement of the bed a few inches to a few feet may be necessary in patient care.

Wheels are lockable. For safety, wheels can be locked when transferring the patient in or out of the bed.[15]

Disadvantages

[

edit

]

Cost

[

edit

]

A hospital bed can cost over US$1000.00; on average with different costs associated with completely manual functions, 2-motor functions and fully electric 3-motor functions (whole bed going up and down). Other costs are associated with bariatric heavy duty models that also offer extra width.[16]

Effect on health of patients

[

edit

]

Hospital beds can make a patient's spine more rounded because a patient who sits up a lot, such as when watching television, tends to slip down.[17] Some of the category a bed manufacturers are providing their beds with a built-in function which acts as an anti-slip. LINET is providing Ergoframe while others have different names.[18]

Safety

[

edit

]

During the 1980s, patient safety had been a concern with hospital beds.

In 1982, a 3-year-old Milwaukee girl hospitalized for pneumonia was killed when crushed by a mechanical hospital bed.[19]

In 1983, an 11-year-old Illinois boy was strangled to death by a hospital bed.[20]

Today's hospital beds are a product of 1800s innovation, steadily improving with each decade's advancements in health care, engineering, and technology. Patient beds today not only provide a place for rest and recuperation, they can actually improve patient outcomes and prevent medical complications. In today's post, we'll look at some of those improvements and suggest directions for the future.

The 1800s brought about not only the first hospital bed, but also introduced two critical components still seen today: Hinged mattresses and side rails. Side rails were a part of the very first hospital bed in 1815, providing safety for the patient and an easier way to move the bed once casters were introduced. The first hinged mattress, invented in 1874, allowed parts of the patient's body to be elevated to promote blood flow or improve respiration. 

The 1900s explosion of inventions in all fields included the hospital bed. New, lighter materials were introduced such as molded plastic and aluminum. Electric buttons replaced hand-cranks for adjusting the bed, and advanced sensors began sending information directly to the nursing staff. These modern beds reflected modern inventions adapted to maximize patient comfort and safety, while also serving helping alleviate some work for the medical staff.

Hospital beds in today's hospitals continue this trend of patient safety and healthcare worker support. Beds can be adjusted to help a patient stand safely by slowly shifting in an armchair configuration, helping save the healthcare worker time and effort. To avoid bed sores, some hospital beds reposition the patient, helping them heal better while allowing healthcare workers to perform other tasks. Many beds are designed to be modular, with special attachments added for respiratory therapy, indwelling devices, or other diagnosing equipment. This modular design saves time while reducing the frequent bed changes that can put patients at risk.

One of the most important protections a bed can offer to patients is to eliminate the danger posed by contamination by disease-causing pathogens. Side rails, buttons, and footboards are frequently touched by patients, healthcare workers, and visitors, leading to significant accumulation of bacteria that reproduces and spreads between cleanings. In studies of contaminated surfaces in patient rooms, side rails repeatedly come out as one of the top two most contaminated surfaces after the patient themselves.

Having this level of bioburden so close to patient must be mitigated in order to have a truly safe patient bed, and the best way to accomplish this is by using biocidal materials (currently only copper-infused EOSCU and copper alloys). More frequent cleaning is unrealistically time-consuming and disturbs the patient, exposing them to more interruptions and the chemicals required to disinfect. A biocidal material that continuously kills bacteria is not only inobtrusive, it also does not lead to the development of resistance and keeps the surface in the benign zone, thereby almost eliminating the risk of disease transmission. 

Hospital-associated infections (HAIs) are caused by dirty surfaces, with either directly transfer pathogens to the patient or indirectly via the hands of a healthcare worker or visitor. Our environment is constantly covered in bacteria, which is not only on surfaces but also floating in the air and living on our hands. This level of contamination, combined with the vulnerability of the typical hospital patient, makes even the most advanced hospital bed a reservoir for disease-causing pathogens. It would be a terrible shame to take such a transformative piece of equipment as the patient bed and continue to allow it to pose an infection risk to patients.
