The CMO medical abbreviation in patient care means comfort measures only, a care plan in which the goal shifts from treating a disease to keeping a person comfortable, usually near the end of life. In hospital administration, CMO can also mean chief medical officer, the physician leader of a hospital or health system.
Families often first see CMO in a hospital chart or hear it during a goals of care meeting. It can feel abrupt to read, so this page explains what the plan includes, what usually stops and what continues, and how it relates to DNR orders, palliative care and hospice.

What comfort measures only means
Under a comfort measures only plan, every part of care is chosen to ease symptoms and support dignity rather than to prolong life. The decision is made by the patient, or by the person legally chosen to speak for them, together with the medical team, usually when treatments are no longer helping or are causing more burden than benefit.
Comfort care is active care. Nurses and doctors keep checking for pain, shortness of breath, restlessness, nausea and dry mouth, and they treat those symptoms promptly. Family time, spiritual support and the person's own wishes become central to the plan.
What usually stops and what continues
Each plan is personal, but a common pattern looks like this.
| Usually stopped | Usually continued or started |
|---|---|
| Routine blood draws and vital sign checks | Pain medicine, given on a schedule or as needed |
| Scans and other tests that will not change comfort | Medicine to ease breathlessness, anxiety or secretions |
| Treatments aimed only at the disease | Mouth care, skin care and repositioning |
| Resuscitation and breathing tubes | Oxygen or a fan if it eases breathing |
| Medicines that do not add comfort | Emotional and spiritual support for patient and family |
Food and drink are usually offered as the person wishes, for pleasure rather than nutrition. The team adjusts the plan as needs change.
CMO compared with DNR, palliative care and hospice
These terms are related but not the same.
| Term | What it means |
|---|---|
| CMO | All care focused on comfort, disease treatment stopped |
| DNR | No CPR if the heart stops; other treatment can continue fully |
| Palliative care | Symptom and support care that can run alongside curative or disease treatment at any stage |
| Hospice | A program of comfort care, often at home or in a facility, usually for people expected to live months rather than years |
A person with a DNR order may still receive surgery or intensive care. Someone on CMO has chosen comfort over those treatments.
The CMO medical abbreviation in hospice and hospital notes
In a hospital, CMO often appears after a family meeting, and it may lead to a move to a quieter room, an inpatient hospice unit, home with hospice, or a skilled nursing or long term care setting (SNF or LTC). Hospice teams themselves more often say comfort care, but they read CMO in transfer papers.
Progress note: "Family meeting held, consensus to transition to CMO, morphine PRN for dyspnea, chaplain consulted." The family and team agreed on comfort care, medicine is ready for breathlessness, and spiritual support was offered.
Questions families often ask
These conversations are hard, and no question is out of place. Families often ask:
- What symptoms should we expect, and how will you treat them?
- Can we stay with our loved one, and can children or pets visit?
- Can the plan be changed if wishes change?
- What support is there for us, now and afterward?
The patient, or whoever speaks for them, may ask to revisit the comfort plan whenever wishes shift.
For students: writing about comfort care
Document the goals of care discussion, who took part and the decision reached. Write comfort measures only in full the first time in a note, since CMO also means chief medical officer in administrative documents. Chart symptom checks and responses to medicine carefully, because comfort is the main measure of good care here. For code status wording and similar orders, browse the chart and order terms hub.
End of life choices are personal and depend on each person's values and condition. The care team, including palliative care and chaplains, can talk through options with you and your family.
Frequently asked questions
What does CMO mean in a hospital?
In patient care it means comfort measures only, a plan focused entirely on relieving symptoms. In hospital leadership, it can mean chief medical officer.
Is CMO the same as DNR?
No. A DNR order only means no CPR if the heart stops, and other treatment can continue. CMO means all care is focused on comfort and treatments aimed at the illness are stopped.
Does comfort measures only mean stopping all medicine?
No. Medicines for pain, breathlessness, anxiety and other symptoms continue or are started. Medicines that do not add comfort are usually stopped.
Is CMO the same as hospice?
They overlap but are not identical. CMO describes the goal of care in an order or chart, while hospice is a program that provides comfort care, often at home or in a dedicated unit.
Can a CMO decision be reversed?
Yes. Plans can change, and the person, or someone legally named to decide for them, can raise it with the team whenever they choose.
