Bedsores, also known as pressure sores or ulcers, develop from prolonged pressure on skin, especially over bony areas. They are caused by impaired blood flow and damage to skin and tissue beneath. People at highest risk are those with limited mobility or confined to bed. Bedsores range in severity from Stage I (redness) to Stage IV (deep wound exposing bone/muscle). Prevention focuses on frequent repositioning to relieve pressure, good nutrition, and skin care.

Bed sores, also known as pressure ulcers, pressure sores or decubitus ulcers are skin lesions which can be caused by friction, humidity, temperature, continence, medication, shearing forces, age and unrelieved pressure. Any part of the body may be affected; bony or cartilaginous areas, such as the elbows, knees, ankles and sacrum are most commonly affected. The sacrum is a triangular bone at the base of the spine and the upper and back part of the pelvic cavity (like a wedge between the two hip bones).

Antibiotic Stewardship by Anushri Srivastava.pptxAnushriSrivastav
Stewardship is the act of taking good care of something.
Antimicrobial stewardship is a coordinated program that promotes the appropriate use of antimicrobials (including antibiotics), improves patient outcomes, reduces microbial resistance, and decreases the spread of infections caused by multidrug-resistant organisms.
WHO launched the Global Antimicrobial Resistance and Use Surveillance System (GLASS) in 2015 to fill knowledge gaps and inform strategies at all levels.
ACCORDING TO apic.org,
Antimicrobial stewardship is a coordinated program that promotes the appropriate use of antimicrobials (including antibiotics), improves patient outcomes, reduces microbial resistance, and decreases the spread of infections caused by multidrug-resistant organisms.
ACCORDING TO pewtrusts.org,
Antibiotic stewardship refers to efforts in doctors’ offices, hospitals, long term care facilities, and other health care settings to ensure that antibiotics are used only when necessary and appropriate
According to WHO,
Antimicrobial stewardship is a systematic approach to educate and support health care professionals to follow evidence-based guidelines for prescribing and administering antimicrobials
In 1996, John McGowan and Dale Gerding first applied the term antimicrobial stewardship, where they suggested a causal association between antimicrobial agent use and resistance. They also focused on the urgency of large-scale controlled trials of antimicrobial-use regulation employing sophisticated epidemiologic methods, molecular typing, and precise resistance mechanism analysis.
Antimicrobial Stewardship(AMS) refers to the optimal selection, dosing, and duration of antimicrobial treatment resulting in the best clinical outcome with minimal side effects to the patients and minimal impact on subsequent resistance.
According to the 2019 report, in the US, more than 2.8 million antibiotic-resistant infections occur each year, and more than 35000 people die. In addition to this, it also mentioned that 223,900 cases of Clostridoides difficile occurred in 2017, of which 12800 people died. The report did not include viruses or parasites

Bedsores 2
1. Bedsores
Bedsores, also
called pressure
sores or pressure
ulcers, are
injuries to skin
and underlying
tissue resulting
from prolonged
pressure on the
skin. Bedsores
most often
develop on skin
that covers bony
areas of the body, such
as the heels, ankles, hips and tailbone.
People most at risk of bedsores are those with a medical condition
that limits their ability to change positions, requires them to use a
wheelchair or confines them to a bed for a long time.
There are two
mechanisms
that
contribute to
pressure
ulcer
development:
external
pressure that
compresses
blood vessels
and friction
and shearing
forces that
tear and injure blood vessels. External pressure applied over an area
of the body, especially over the bony prominences can result in
obstruction of the blood capillaries, which deprives tissues of oxygen
and nutrients, causing ischemia (deficiency of blood in a particular
area), hypoxia (inadequate amount of oxygen available to the cells),
edema, inflammation, and, finally, necrosis and ulcer formation.
Ulcers due to external pressure occur over the sacrum and coccyx,
followed by the trochanter and the calcaneus(heel). Friction is
damaging to the superficial blood vessels directly under the skin. It
occurs when two surfaces rub against each other. The skin over the

2. injured when patients are pulled or slid over bed sheets while being moved up in bed or transferred onto a
stretcher. A shear is a separation of the skin from underlying tissues. When a patient is partially sitting up
in bed, their skin may stick to the sheet, making them susceptible to shearing in case underlying tissues
move downward with the body toward the foot of the bed. This may also be possible on a patient who
slides down while sitting in a chair.
In addition to pressure, friction, and shear, there are more risk factors of pressure ulcers. Physiological
(intrinsic) and non-physiological (extrinsic)) factors that may place a patient at risk include diabetes
mellitus, peripheral vascular disease, cerebral vascular accident and hypotension. Other factors are age
of 70 years and older, current smoking history, dry skin, low body mass index, impaired mobility, altered
mental status, urinary and fecal incontinence, malnutrition, physical restraints, malignancy, history of
pressure ulcers.
Knowing patient’s condition, risk factors for pressure ulcers, prevention measures are very important. For
example, older adults have a higher risk of developing pressure ulcers because chronic diseases, more
common in this age group, may compromise circulation and oxygenation of dermal structures. The
nutrition and hydration status of elderly may as well predispose them to pressure ulcer formation.
Bedsores fall into one of four stages based on their severity. The National Pressure Ulcer Advisory Panel,
a professional organization that promotes the prevention and treatment of pressure ulcers, defines each
stage as follows:
Stage I
The beginning stage of a pressure sore has the following characteristics:
The skin is not broken.
The skin appears red on people with lighter skin color, and the skin doesn't briefly lighten (blanch)
when touched.
On people with darker skin, the skin may show discoloration, and it doesn't blanch when touched.
The site may be tender, painful, firm, soft, warm or cool compared with the surrounding skin.
Stage II
At stage II:
The outer layer of skin (epidermis) and part of the underlying layer of skin (dermis) is damaged or
lost.
The wound may be shallow and pinkish or red.
The wound may look like a fluid-filled blister or a ruptured blister.
Stage III
At stage III, the ulcer is a deep wound:
The loss of skin usually exposes some fat.
The ulcer looks crater-like.
The bottom of the wound may have some yellowish dead tissue.
The damage may extend beyond the primary wound below layers of healthy skin.
Stage IV
A stage IV ulcer shows large-scale loss of tissue:
3. The wound may expose muscle, bone or tendons.
The bottom of the wound likely contains dead tissue that's yellowish or dark and crusty.
The damage often extends beyond the primary wound below layers of healthy skin.
Unstageable
A pressure ulcer is considered unstageable if its surface is covered with yellow, brown, black or dead
tissue. It’s not possible to see how deep the wound is.
Deep tissue injury
A deep tissue injury may have the following characteristics:
The skin is purple or maroon but the skin is not broken.
A blood-filled blister is present.
The area is painful, firm or mushy.
The area is warm or cool compared with the surrounding skin.
In people with darker skin, a shiny patch or a change in skin tone may develop.
Pressure ulcers may be caused by inadequate blood supply and resulting reperfusion injury when blood
re-enters tissue. A simple example of a mild pressure sore may be experienced by healthy individuals
while sitting in the same position for extended periods of time: the dull ache experienced is indicative of
impeded blood flow to affected areas. Within 2 hours, this shortage of blood supply, called ischemia, may
lead to tissue damage and cell death. The sore will initially start as a red, painful area. The other process
of pressure ulcer development is seen when pressure is high enough to damage the cell membrane of
muscle cells. The muscle cells die as a result and skin fed through blood vessels coming through the
muscle die. This is the deep tissue injury form of pressure ulcers and begins as purple intact skin.
4. Healing time is prolonged for higher stage ulcers. While about 75% of Stage II ulcers heal within eight
weeks, only 62% of Stage IV pressure ulcers ever heal, and only 52% heal within one year. It is important
to note that pressure ulcers do not regress in stage as they heal. A pressure ulcer that is becoming
shallower with healing is described in terms of its original deepest depth.
Common sites of pressure sores
For people who use a wheelchair, pressure sores often occur on skin over the following sites:
Tailbone or buttocks
Shoulder blades and spine
Backs of arms and legs where they rest against the chair
For people who are confined to a bed, common sites include the following:
Back or sides of the head
Rim of the ears
Shoulders or shoulder blades
Hip, lower back or tailbone
Heels, ankles and skin behind the knees
Prevention
Bedsores are easier to prevent than to treat, but that doesn't mean the process is easy or uncomplicated.
And wounds may still develop with consistent, appropriate preventive care.
Your doctor and other members of the care team can help develop a good strategy, whether it's personal
care with at-home assistance, professional care in a hospital or some other situation.
Position changes are key to preventing pressure sores. These changes need to be frequent, repositioning
needs to avoid stress on the skin, and body positions need to minimize pressure on vulnerable areas.
Other strategies include taking good care of your skin, maintaining good nutrition, quitting smoking and
exercising daily.
5. In addition, adequate intake of protein and calories is important. vitamin C has been shown to reduce the
risk of pressure ulcers. People with higher intakes of vitamin C have a lower frequency of bed sores in
those who are bedridden than those with lower intakes. Maintaining proper nutrition in newborns is also
important in preventing pressure ulcers. If unable to maintain proper nutrition through protein and calorie
intake, it is advised to use supplements to support the proper nutrition levels. Skin care is also important
because damaged skin does not tolerate pressure. However, skin that is damaged by exposure to urine
or stool is not considered a pressure ulcer.
Repositioning in a bed
Consider the following recommendations when repositioning in a bed:
Reposition yourself frequently. Change your body position every two hours.
Look into devices to help you reposition. If you have enough upper body strength, try
repositioning yourself using a device such as a trapeze bar. Caregivers can use bed linens to help lift
and reposition you. This can reduce friction and shearing.
Try a specialized mattress. Use special cushions, a foam mattress pad, an air-filled mattress or a
water-filled mattress to help with positioning, relieving pressure and protecting vulnerable areas. Your
doctor or other care team members can recommend an appropriate mattress or surface.
Adjust the elevation of your bed. If your hospital bed can be elevated at the head, raise it no more
than 30 degrees. This helps prevent shearing.
Use cushions to protect bony areas. Protect bony areas with proper positioning and cushioning.
Rather than lying directly on a hip, lie at an angle with cushions supporting the back or front. You can
also use cushions to relieve pressure against and between the knees and ankles. You can cus hion or
''float'' your heels with cushions below the calves
Skin care
Protecting and monitoring the condition of your skin is important for preventing pressure sores and
identifying stage I sores early so that you can treat them before they worsen.
Clean the affected skin. Clean the skin with mild soap and warm water or a no-rinse cleanser.
Gently pat dry.
Protect the skin. Use talcum powder to protect skin vulnerable to excess moisture. Apply lotion to
dry skin. Change bedding and clothing frequently. Watch for buttons on the clothing and wrinkles in
the bedding that irritate the skin.
Inspect the skin daily. Inspect the skin daily to identify vulnerable areas or early signs of pressure
sores. You will probably need the help of a care provider to do a thorough skin inspection. If you have
enough mobility, you may be able to do this with the help of a mirror.
Manage incontinence to keep the skin dry. If you have urinary or bowel incontinence, take steps to
prevent exposing the skin to moisture and bacteria. Your care may include frequently scheduled help
with urinating, frequent diaper changes, protective lotions on healthy skin, or urinary catheters or
rectal tubes.
