Glossary of Terms
Glossary of Terms
Health care providers and others often use terms that you may find confusing or have never heard before. This list offers a simple explanation for many of these terms. Note that it does not include most terms associated with specific diseases or treatments. To find the meanings of these terms, ask your doctor or nurse, or look up the term in a medical dictionary, such as MedLinePlus. Your local library is also a good resource.
Some definitions have words in bold, which means that either the word or term is defined separately in this listing or there is a link to a website you may find helpful.
Daily functions such as getting dressed, eating, taking a shower or bath, going to the bathroom, and getting into a bed or chair. The amount of help a person needs with ADLs is often used to assess whether he or she meets the requirements for long-term care services in a nursing home.
Medical care for health problems that are new, quickly get worse, or result from a recent accident. Acute care is usually given in a hospital or its Emergency Department.
Written instructions to health care professionals about the amount and type of medical care and treatment a person wants. Advance directives are used when people are too ill or injured or are unable for other reasons to state these wishes for themselves.
are two types of advance directives. One describes the type of care a person
wants. The other names someone else (health care proxy or agent) to make
medical choices, if needed. Each state has its own laws.
Adult Day Care
that provide social and recreational activities and health services to adults
who are physically (body) or cognitively (mind) impaired. These take place in
supervised and structured settings.
Adult Protective Services (APS)
State and local agencies that investigate (look into) reports of abuse or neglect. They also offer services to adults (18 years and older) who are physically, sexually, financially, or emotionally abused by someone involved in care. These abuses include neglect, exploitation, or abandonment. Referrals to APS can be done when either the person neglects him or herself, or when someone else neglects or abuses an adult person.
disease is a condition in which nerve cells in parts of the brain start to die.
It is progressive, which means that mental and
physical functions decline over time. Alzheimer's disease is the most common
(but not only) cause of dementia.
care given in an outpatient setting (where the patient is not admitted to a
facility). This is usually a doctor’s office or clinic, but may be a hospital.
It includes diagnosis, observation (watching), treatment, and rehabilitation.
The term comes from the word “ambulation” (walking), even though many patients
who cannot walk are treated in ambulatory care settings.
way to dispute (disagree with) a health care facility decision to an
independent agency called a Quality Improvement Organization (QIO). Often,
appeals are about decisions to discharge patients. There are strict rules and
deadlines to follow. If the QIO denies the appeal (that is, if it decides that
the facility’s discharge decision was right), the patient or family member must
pay for care given while the appeal was reviewed. To find the QIO in your
state, go to http://qiosynergy.org/default.aspx?ID=qios.
Area Agency on Aging (AAA)
that gets state and federal funding to plan and coordinate services for people
over age 60 within a local area. In some cities, towns and states, the AAA is
also known as Department for the Aging. AAAs run program such as National Family Caregiver Support Programs. To
find the AAA in your area, call the Eldercare Locator at 1-800-677-1116 or
visit the Department of Health & Human Services' Eldercare Locator.
Assisted Living or Assisted Living Facility (ALF)
residence for people who do not want to, or cannot, live independently (on
their own) but do not need nursing home care. ALFs offer different kinds of
services, including social activities, supervision, and some health care
services (but not as many as in a nursing home). ALFs are privately owned and
or special equipment (“adaptive equipment” or “independent living aids”) that
help older or disabled people perform ADLs and other tasks. These tools include
telephones with enhanced amplification (for those who are hard of hearing),
special kitchen supplies, computer programs, and other types of technology.
doctor at a teaching hospital. This doctor is often in charge of (responsible
for) a patient’s care. The attending doctor supervises fellows (postgraduate

Legal term for someone granted Power of Attorney (POA).
A term used in skilled nursing facilities to define the length of time the facility will hold a patient’s bed in case he or she has to leave the facility for care elsewhere, such as hospital, or for any other reason. There is a fee for holding a bed and each facility has its own policies and fees. If a patient has to leave the facility and did not secure a bed hold, there is no guarantee that he or she will be able to return to that facility for continuation of care and treatment.
Pressure or “bed” sores are wounds that occur when a patient is not moved frequently in bed or wheelchair. The medical term is “decubiti” (de-CUBE-it-eye). They are graded from Stage I through IV, with IV being the most serious.
Person who is entitled to receive services from a health insurance plan or program such as Medicare and Medicaid
In health care settings, “capacity” refers to a patient’s ability to understand and use medical information (such as treatment options, risks, and benefits) when making decision and choices about medical care. Capacity varies; a person may have the capacity to make some choices, but not others. A “health care proxy” can act as the patient’s decision maker if the patient loses capacity due to illness or injury. Capacity is different from competence; only a judge can declare someone incompetent (unable to make decisions for themselves).
Nurse, social worker, or other health care worker who plans and coordinates services for a patient’s care. This person usually works for an agency or facility. Also see geriatric care manager.
Doctors, nurses, and social workers may use the term “caregiver” when talking about themselves. “Caregiver” can also mean family members, friends, and neighbors who provide on-going help and assistance to people who are ill, frail, or disabled. Other terms include family caregiver, informal caregiver, and formal caregiver.

It also considers the caregiver’s own need for support and/or other services.
A group of people who meet regularly to help each other by discussing feelings, common problems, ways of coping, available resources, and many other issues related to caregiving. Support groups may be for caregivers of patients who have certain diseases (such as cancer or Alzheimer’s Disease). They can also be for certain types of caregivers (such as spouses or adult children). Some support groups meet in person while others are only online or by telephone.
A detailed written plan that includes needed tasks for patient care. It likely includes services provided by nurses, therapists, home health aides, and attendants. A good care plan should also list the tasks that family caregivers (who often do many of the tasks) do.
Person trained and certified to assist patients with non-clinical tasks such as eating, walking, and personal care (like taking a bath). This person may be called a “nursing assistant” in the hospital. Also see home health aide.

Problems that affect how clearly a person thinks, learns new tasks, and remembers events that just happened or from long ago.
An order (signed by a doctor) that says that the patient should not be resuscitated (given Cardiopulmonary Resuscitation, or CPR to restart a heart beat) if he or she is at home when the heart stops beating. If emergency services are called, this order must be given to the medical team. Also see DNR.
A legal tem meaning that a person is able to make decisions for themselves. To do that, he or she has to be an adult (18 years of age or older) and have capacity, which means the ability to understand and use information when making decisions. A judge is the only one who can declare a person “incompetent” (lacking the ability to make decisions). This happens in a guardianship hearing.
Also called personal care. It is the kind of help or supervision people need with daily tasks such as getting dressed, eating, taking a shower or bath, going to the bathroom, and getting into a bed or chair. Custodial care may be given at home by family members or by home care aides or personal care attendants. This care is not paid for by insurance unless the patient also needs skilled care from a nurse or therapist.

Supplies for incontinence (such as adult diapers and bed protectors) are usually not covered by insurance but may be covered by Medicaid in some states.
A DNI order instructs health care workers not to insert a breathing tube through the patient’s nose or mouth into the throat once breathing has stopped. A DNI order is part of an advance directive and is separate from a DNR order.
A DNR order instructs health care workers not to perform cardiopulmonary resuscitation (CPR) or other actions to restart a person’s heart or breathing once it has stopped. By law, a DNR order must be offered to patients and families. Signed DNRs must be part of the patient’s medical chart. A DNR order is part of an advance directive and is separate from a DNI order.

Any family member, partner, friend, or neighbor who provides or manages the care of someone who is ill, disabled, or frail. There may be more than one family caregiver involved in a person’s care.
Sometimes family caregivers are referred to as informal caregivers. This is meant to show that they are different from formal caregivers (paid health care workers). But many caregivers do not like the term “informal” because it implies less skill and commitment.

A term used to describe the care needed by someone who must depend on others for help with daily needs. LTC is designed to help people with chronic health problems or dementia live as independently as possible. While many people think that long-term care happens only in a nursing home, in fact most long-term care is given by family caregivers in the patient’s home.
Private insurance designed to cover (pay for) long-term care expenses at home or in a facility other than a hospital. There are many long-term care insurance policies with a wide range of benefits (services they pay for). Medicare and Medicare supplemental insurance (Medigap) do not pay for this type of care.

The Outcome and Assessment Information Set (OASIS) is a series of questions about a home care patient to determine needs and measure outcomes. Medicare requires a home care agency to fill out this survey when opening a case for an adult patient, when there is a significant change in condition, when a patient is transferred to a hospital, when (if) the patient returns home, or when the patient dies or is discharged from the agency services. The questions cover many aspects of the patient’s diagnosis, clinical condition, living arrangements, and ability to manage on his or her own. A few questions concern the “primary caregiver” – who that person is, how often the patient receives care from that person, and what kinds of care are provided. Because a patient may not be able to give all the answers or may be unwilling to reveal how much help he or she needs, it is a good idea for the family caregiver to be present at this initial evaluation.
Licensed health care professional who helps patients learn again how to do Activities of Daily Living (ADLs). OTs can also help plan ways to adapt (change) a person’s home so he or she can be as independent (do tasks alone) as possible.
Care that focuses on the relief of pain, symptoms, and stress of serious illness. The goal is to improve quality of life for patients and families. Palliative care is appropriate at any point in an illness, not just end-of-life care, and it can include treatments that are intended to cure as well as comfort. Palliative care is given by trained workers in a hospital, home, nursing home, or hospice. For more information, visit GetPalliativeCare.org.

A way to gather patient information so as to assess functional needs (what tasks people need help with) and eligibility for services (what services they can get). Information may include health status, financial (money) status, ability to perform ADLs and IADLs, mental status, and living situation.
Listing of ways a health care facility will treat patients with dignity and respect. It includes how patients can fully participate (take part) in making health care choices. To learn more, visit the American Hospital Association's A Patient's Bill of Rights.
Electronic device that allows a person to call for emergency help at home. The device connects to the patient’s phone and is programmed to signal a response center when the "help" button is pressed. The patient may also wear a “help” button as a necklace or bracelet. This allows the person to move freely around his or her home.
