Question 1
What do I chart about language?
The essentials: the patient's preferred language, that a qualified interpreter was offered and used, the service and mode (agency, video, phone), the interpreter's ID number when the service provides one, and what was covered through interpretation. If a patient declines an interpreter, chart the offer, the declination, and that a qualified interpreter was available.
Chart what you did, not what you meant. 'Family interpreted' charted plainly is an honest record of a practice the institution prohibits; the chart is where that becomes visible, which is why the practice is not worth starting.
