Form 1 (6427-41)

Application by Physician for Psychiatric Assessment

Demande d'évaluation psychiatrique faite par un médecin

A Form 1 reaches a family physician when a patient in front of them, or seen in the last few days, appears to be at risk because of a mental disorder. It rests on what you observed and what others told you, and it authorizes police or anyone else to take the person to a psychiatric facility, where they can be held for up to 72 hours for assessment.

What the Form 1 is for

A Form 1 is the application a physician makes under section 15 of the Mental Health Act for a psychiatric assessment. It authorizes taking the person into custody and bringing them to a psychiatric facility, but it doesn’t admit them. At the facility, an attending physician decides within 72 hours whether to release them, admit them voluntarily, or certify them on a Form 3.

It’s often confused with a Form 2, which a justice of the peace issues when the person hasn’t been examined by a physician, and with a Form 3, which only the attending physician at the facility can sign.

Who completes it

Only the physician who personally examined the person completes and signs the Form 1. The examination must be within the past seven days. The patient doesn’t complete any part. Once the person is detained at the facility, the attending physician there notes the date and time detention began and the date and time they gave the person a Form 42.

How to fill in the application

Physician and examination details

Print your name, address, telephone and fax, the date you examined the person, their full name, and their home address. The Act requires the date of examination on the form, and the seven-day clock for signing runs from it.

Box A: serious harm test

Box A has two parts, and both are needed. The past or present test asks whether the person has threatened or attempted self-harm, behaved violently toward someone, caused someone to fear bodily harm, or shown a lack of competence to care for themselves. The future test asks whether a mental disorder will likely result in serious bodily harm to the person or another, or serious physical impairment. Check at least one item in each part.

Box B: incapable patients who meet the specified criteria

Use Box B for a person with a previously treated, recurring disorder who improved with treatment and is now deteriorating. All five conditions must be met, including that the person is incapable of consenting to treatment in a psychiatric facility and that their substitute decision-maker has consented. If you can’t confirm the substitute decision-maker’s consent, Box B doesn’t apply.

Your observations and facts from others

Each box asks for the information you based your opinion on, split into your own observations and facts communicated to you by others. The Act requires you to keep the two apart. Write what you saw and heard in the examination, then what family, police, or other clinicians reported, with who said it.

Signature, date and time

Sign with today’s date and time after confirming you made careful inquiry into the facts. The authority to take the person into custody lasts seven days from the day you sign.

Common reasons it’s found defective

  • Signed more than seven days after the examination.
  • Box A completed with the past or present test but no future test, or the reverse.
  • Box B used without the substitute decision-maker’s consent.
  • Observations and third-party reports run together, or no facts given at all.
  • Missing date of examination, signature, or time.
  • Signed by someone who isn’t a physician.

Submitting and who pays

The form isn’t sent to the ministry. It goes with the person to the psychiatric facility, usually carried by police or ambulance, and a copy stays in your chart. OHIP pays the physician under fee code K623, application for psychiatric assessment, which covers the history, examination, notifications, and completing the form.

Questions

Questions we hear a lot.

How long is a Form 1 valid?

You must sign it within seven days of examining the person. Once signed, it authorizes anyone to take the person to a psychiatric facility for seven days, counting the day of signature, and the facility can hold them for up to 72 hours.

Can a nurse practitioner sign a Form 1?

No. Section 15 of the Mental Health Act gives the power to a physician, which the Act defines as a legally qualified medical practitioner. A justice of the peace can order an examination under a different section.

Can the physician who signed the Form 1 also sign the Form 3?

No. The Act says the physician who completes the certificate of involuntary admission can't be the one who completed the application for psychiatric assessment.

Is a Form 1 billable to OHIP?

Yes. The Schedule of Benefits lists K623, application for psychiatric assessment, which includes the history, examination, notifying the patient, family and authorities, and completing the form.

Is patient information secure?

Yes. Medulla has a SOC 2 Type II report from an independent auditor, is HIPAA, PIPEDA, and PHIPA compliant, and is built and hosted in Canada, so patient data stays in the country and never gets pasted into consumer AI tools. Everything is encrypted in transit and at rest. See how we protect patient data.
