The Short Answer
A clear portal message states your request in the first sentence, gives a short timeline, and says what response you're expecting. Care teams that use secure messaging generally set up staff to acknowledge new messages quickly and route them to the right person — but that only works well if the message itself is specific. Vague messages (“not sure if this is anything”) take longer to triage because the care team has to write back and ask what you actually need.
When a Portal Message Is the Wrong Tool
Secure patient portal messaging is built for non-urgent communication, not emergencies. Research on how patients actually use portal messaging found that even experienced users are often unsure what counts as an appropriate “non-urgent” message — so if you're unsure too, you're not alone.
Many portals display a notice reminding patients that messages are for non-urgent issues, that a typical response can take a day or two, and to call 911 or seek emergency care if the concern feels urgent. If you have chest pain, trouble breathing, sudden severe symptoms, or anything that cannot safely wait, contact emergency services or your care team by phone instead of sending a portal message.
What Non-Emergency Portal Messages Are Good For
According to HHS's Office of the National Coordinator for Health Information Technology (ONC), secure portal messaging works well for things like:
- Brief updates or follow-up questions after a recent visit
- Clarifying instructions or advice you received during a visit
- Correcting a misunderstanding before it becomes a bigger problem
- Recording details like a referral name or post-visit instructions
- Prescription refill requests, where your practice allows them by message
One advantage of messaging is that it avoids “telephone tag” — the back-and-forth of missed calls and voicemails — and many practices have staff review incoming messages first, so a clinician only needs to get involved when the message actually requires their judgment.
A Known-Versus-Unknown Box
Before you write, separate what you already know from what you're asking the care team to tell you. This keeps the message focused.
- What you know: your symptom or question, when it started, what makes it better or worse, and anything you've already tried.
- What you're asking: whether you need a visit, whether a medication needs adjusting, what a result means, or what to do next.
Portal messaging is generally not the right channel for a full diagnosis or a decision that needs an exam — the ONC guidance notes that practices typically set expectations up front about what kinds of questions can be answered by message versus what needs a call or visit.
A Practical Message-Writing Checklist
- Write a descriptive subject line — something like “Prescription refill question” or “Follow-up on last visit,” so the message routes to the right person quickly.
- State your request in the first sentence. Example: “I'd like to know if I should schedule a visit for a symptom I've had for five days.”
- Give a timeline. When did it start? Has it changed, stayed the same, or gotten worse?
- List anything you've already tried, including over-the-counter remedies, and whether it helped.
- Mention current medications that could be related, if relevant.
- Keep one topic per message where possible, so each request can be tracked and closed out on its own.
- Say what response you expect — advice, a callback, a refill, or a scheduled visit — so the care team knows how to close the loop.
What to Expect After You Send It
Response times vary by practice, but many set an internal goal of acknowledging messages within about one business day, with fuller answers to more complex questions sometimes taking longer. If your question turns out to need an exam or testing, expect the reply to be a recommendation to schedule a visit rather than an answer within the message thread — that's a normal and appropriate outcome, not a sign the system failed.
Also keep in mind: portal messages generally become part of your medical record, so it's worth being specific and factual, the same way you would be in a visit.
