Inpatient or Impatient: What Is the Difference?

Use inpatient when talking about a patient who stays in a hospital for treatment. Use impatient when describing someone who is restless, annoyed by waiting, or eager for something to happen.

It is easy to mix up inpatient or impatient. The words look almost identical, and both contain the word patient, but their meanings are completely different.

Inpatient is mainly a medical term. It refers to a person receiving treatment while staying in a hospital or similar medical facility. Impatient is an adjective describing a person who finds it difficult to wait calmly or who wants something to happen quickly.

The easiest memory trick is simple: inpatient = in the hospital; impatient = unable to wait patiently.

Inpatient or Impatient: What Is the Main Difference?

The difference comes down to context.

Word	Part of Speech	Meaning	Example
Inpatient	Noun or adjective	A patient staying in a hospital, or care provided to such a patient	She received inpatient treatment.
Impatient	Adjective	Restless, annoyed by waiting, or eager	He became impatient while waiting.

Merriam-Webster defines an inpatient as a hospital patient who receives lodging and treatment. Collins also uses in-patient as both a noun and an adjective. Impatient, meanwhile, means not patient, particularly when someone becomes restless or short-tempered because of delay or irritation.

What Does Inpatient Mean?

Inpatient is a medical term.

As a noun, it refers to someone who has been admitted to a hospital or medical facility and stays there while receiving treatment.

For example:

• She was admitted as an inpatient after surgery.
• The hospital currently has several inpatients receiving specialist treatment.
• He remained an inpatient while doctors monitored his condition.

Inpatient can also describe medical services or facilities intended for patients who have been admitted.

For example:

• He needs inpatient care.
• The hospital has a separate inpatient unit.
• She entered an inpatient treatment program.

In each case, the word relates to receiving care while admitted to a healthcare facility. Collins records this adjectival use as well as the noun form.

What Does Impatient Mean?

Impatient is an adjective describing a lack of patience.

A person may become impatient because they have been waiting too long, because progress is slow, or because another person’s mistakes are frustrating them. Cambridge describes an impatient person as someone who becomes easily annoyed because of waiting or another person’s mistakes.

For example:

• She became impatient while waiting for the bus.
• Don’t be impatient. Your food will be ready soon.
• He sounded impatient on the phone.
• The children grew impatient during the long journey.
• I’m impatient to hear the results.

Merriam-Webster also notes that impatient can describe someone who is eagerly desirous of something.

So the word does not always mean angry. Sometimes it simply suggests strong eagerness.

Why Are Inpatient and Impatient So Easy to Confuse?

Only one letter separates the key prefixes:

• inpatient begins with in-
• impatient begins with im-

The words also share patient, which itself can have two different common meanings.

A patient can be a person receiving medical care. The adjective patient can also describe someone who can wait calmly without becoming annoyed. Merriam-Webster records this adjective as showing calmness or restraint under difficulty or delay.

This explains the two related words:

in + patient → inpatient
A medical patient staying in a healthcare facility.

im + patient → impatient
Not patient or unable to wait calmly.

The meanings therefore come from different uses of the word patient.

Inpatient vs. Outpatient

When inpatient is used medically, its natural opposite is outpatient, not impatient.

An outpatient receives medical diagnosis or treatment without being hospitalized overnight, according to Merriam-Webster.

Compare:

• She received inpatient treatment after the operation.
• He attended the clinic as an outpatient.

A useful pair to remember is:

Inpatient ↔ Outpatient

By contrast:

Patient ↔ Impatient

Keeping these two pairs separate makes the spelling easier.

Patient vs. Impatient

When describing personality or behavior, the opposite relationship is between patient and impatient.

Patient

A patient person can wait or deal with difficulty without quickly becoming annoyed.

• Please be patient while the page loads.
• She is very patient with young children.

Impatient

An impatient person has difficulty waiting calmly.

• He became impatient after waiting for an hour.
• She gave me an impatient look.

Merriam-Webster defines impatient directly in relation to being “not patient,” especially when dealing with delay or irritation.

Is It Inpatient Care or Impatient Care?

The correct medical expression is inpatient care.

Correct:

• The doctor recommended inpatient care.
• She was transferred to an inpatient unit.
• The facility provides inpatient treatment.

Incorrect for this meaning:

• The doctor recommended impatient care.

Impatient care would literally describe care that is somehow impatient, which is not the intended medical meaning.

When the subject involves hospitals, admission, medical treatment, or hospital units, inpatient is usually the word you need.

Is It Inpatient or Impatient With Someone?

Use impatient with when describing frustration with a person.

For example:

• She was impatient with the slow cashier.
• Try not to become impatient with beginners.
• He gets impatient with people who arrive late.

Cambridge specifically gives impatient with as a normal construction for describing annoyance with someone’s actions or mistakes.

Do not use inpatient with for this meaning.
