Patients

Patient records are identified by their file number (MRN), unique within a clinic.

Method	Path	Permission
`GET`	`/api/patients`	`patient:read`
`GET`	`/api/patients/{fileNumber}`	`patient:read`
`POST`	`/api/patients`	`patient:write`
`PUT`	`/api/patients/{fileNumber}`	`patient:write`
`POST`	`/api/patients/{fileNumber}/transfer`	`patient:write`
`POST`	`/api/patients/{fileNumber}/labs`	`lab:write`
`DELETE`	`/api/patients/{fileNumber}`	`patient:delete`

Role-based scoping

Two roles see a filtered view, enforced server-side: doctors (without an additional elevated role) see only patients whose primary provider they are; reception sees demographics only — clinical fields (medications, problems, labs, encounters, vitals) are omitted from their responses and ignored in their writes.

Endpoints

List patients

curl -b cookies.txt http://localhost:4000/api/patients

const patients = await fetch('http://localhost:4000/api/patients', {
  credentials: 'include',
}).then((r) => r.json());

Returns an array of full patient objects (see below).

Get a patient

curl -b cookies.txt http://localhost:4000/api/patients/1042

{
  "fileNumber": "1042",
  "name": "Hodan Warsame",

}

404 if the file number doesn't exist in your active clinic.

Create a patient

POST /api/patients with the full record. Returns 201 and the created patient.

Field	Type	Notes
`fileNumber`	string	Required. Digits only; unique per clinic
`name`	string	Required
`age`	number	Required. 0–150
`sex`	`"M"` \| `"F"`	Required
`status`	`"active"` \| `"inpatient"` \| `"discharged"`	Required
`initials`	string	Required. 1–4 characters
`pcp`	string	Display name of the primary care provider
`primaryProviderId`	string \| null	User id of the responsible clinician
`alerts`	string[]	Prominent warnings
`allergies`	array	`{ substance, reaction, severity: mild\|moderate\|severe }`
`medications`	array	`{ name, dose, frequency }`
`problems`	array	`{ label, since }`
`labs`	array	`{ name, value, flag: normal\|high\|low\|critical, takenAt }`
`encounters`	array	`{ date, type, provider, summary }`
`vitals`	object	`{ bp, hr, temp, spo2, takenAt }`
`vitalsTrend`, `labTrend`	object	`{ label, unit, points: number[] }`

Update a patient

PUT /api/patients/{fileNumber} takes the same full payload as create (the app sends the whole record on edit) and returns the updated patient.

Transfer a patient

Reassign the patient to another clinician in the same clinic:

curl -b cookies.txt -X POST http://localhost:4000/api/patients/1042/transfer \
  -H "Content-Type: application/json" \
  -d '{ "providerId": "usr_def456" }'

400 if the provider isn't a member of the clinic; returns the updated patient.

Append lab results

POST /api/patients/{fileNumber}/labs appends one or more analysis results to the record without replacing anything else — unlike the full PUT update. It is gated by the dedicated lab:write permission (the Lab role and full clinicians), so lab staff can submit results without patient-edit rights.

Field	Type	Notes
`labs`	array	Required. 1–50 entries
`labs[].name`	string	Required. Test name, e.g. `"Hemoglobin"`
`labs[].value`	string	Required. e.g. `"14.2 g/dL"`
`labs[].flag`	enum	Required. `normal` \| `high` \| `low` \| `critical`
`labs[].takenAt`	string	Required. Display date, e.g. `"Jun 11, 2026"`

curl -b cookies.txt -X POST http://localhost:4000/api/patients/1042/labs \
  -H "Content-Type: application/json" \
  -d '{ "labs": [{ "name": "Hemoglobin", "value": "14.2 g/dL", "flag": "normal", "takenAt": "Jun 11, 2026" }] }'

Returns 201 with the full updated patient; 404 if the file number doesn't exist. New results are appended after the existing ones.

Delete a patient

curl -b cookies.txt -X DELETE http://localhost:4000/api/patients/1042

Returns 204. Requires patient:delete (owner or admin).

Every mutation is written to the activity log and notifies the clinic's members in real time.
