Patient Outreach Strategies: When to Call, Text or Write

The best patient outreach strategies start from the message, not the tool: decide what the patient needs to know or do, then pick the channel that gets that across with the least effort on their side. A call suits a conversation, a text suits a short nudge, and a letter suits a formal notice or a patient you cannot reach any other way. This guide sets out when to use each one, how to combine them, and what to check before anything goes out.

Start with what the patient has to do

Before choosing a channel, write the outreach down in one sentence: "Patients due for a wellness visit need to call us back" or "Patients whose device shipped need to know it is on the way." That sentence answers three questions.

Does the patient need to talk to someone? Questions, decisions, consent and anything sensitive need a conversation.
Does the patient only need to know something? A short fact, a confirmation or a nudge can be read in a few seconds.
Does the message need to be on paper? A formal notice, a change to the patient's care or a record the patient may want to keep belongs in a letter.

If you cannot write the sentence, the outreach is not ready. A vague message sent on any channel produces vague replies and repeat calls.

When to call, text or send a letter

Each channel has jobs it does well. Match the job to the channel, not to whichever tool is open.

When a phone call is the right channel

Call when the outcome depends on a conversation. Good cases:

Enrolling a patient in a program, or explaining what a program involves
Following up on something clinical the provider asked the team to check
Asking for consent and recording the answer
Reaching a patient who did not respond to a text or letter
Anything where the patient is likely to have questions

A call costs the most staff time, so plan it. Give the caller the patient's context before they dial, a short script with the points to cover, and a fixed list of outcomes to record afterwards (reached, left a voicemail, no answer, asked to be called back, asked not to be called). Those outcomes are what tell you later whether the outreach worked.

Leave voicemails short and free of clinical detail: the practice name, a callback number and a reason that does not reveal a diagnosis.

When a text is the right channel

Text when the patient only needs a fact or a small action. Good cases:

Telling a patient their device has shipped or been delivered
A follow-up after a visit, with a number to call
A short reminder of something the patient already agreed to
Asking a patient to call the practice back

Keep texts to a single message, sign them with the practice name, and keep clinical detail out. HIPAA permits texting patients, but the minimum necessary standard still applies, so a text should say "please call us about your recent results" rather than the results themselves.

Texting has its own consent and opt-out rules under the TCPA, and they are stricter for automated and marketing messages. Read our guide to patient text message consent before you send texts to a list, and talk to your counsel about how the rules apply to your practice.

When a letter is the right channel

Send a letter when the message must be formal, permanent or delivered to someone who does not use a mobile phone. Good cases:

A notice that a program or service has ended for the patient
A condolence letter to a family
Patients with no mobile number on file, or who refused texts
A message the patient may want to keep or show someone else

A letter is slow and cannot be answered in the same channel, so always include a phone number and say what the patient should do next. Keep the wording plain and short; a one-page letter is read, and a three-page one is filed.

Calls, texts and letters side by side

	Call	Text	Letter
Best for	Conversations, consent, questions	Short facts and nudges	Formal notices, patients without a mobile
Speed	Immediate if answered	Immediate	Days
Staff time per patient	Highest	Lowest	Low once the wording is written
Patient can reply	In the moment	By text or by calling	By calling the number in the letter
Consent and opt-out rules	TCPA rules for automated calls, Do Not Call requests	TCPA rules for texts, STOP replies	Fewer channel rules, but content still needs care
Watch out for	Calling hours, repeat attempts	Clinical detail in the message	Out-of-date addresses

How to sequence channels without overwhelming patients

Some patients do not read texts and some do not answer unknown numbers, so one channel alone leaves patients unreached. A simple sequence uses the cheapest channel first and the most personal one for patients who did not respond.

Send a short text to patients who can receive texts, with a number to call.
After a few days, call the patients who did not respond or could not be texted.
Leave one voicemail, then try again later on a different day and time.
For patients you still cannot reach, send a letter with the same request.
Record the final outcome for each patient so nobody is contacted again by mistake.

Set a limit on attempts before you start, and stop as soon as the patient responds or asks you to stop. A patient who asked not to be contacted goes on your Do Not Call list straight away, and stays there until they tell you otherwise.

Our step-by-step guide to running a patient outreach campaign shows how to turn this sequence into a list your team works through.

What to check before any outreach goes out

Consent and refusals. Who has agreed to texts, who has refused, and who is on your Do Not Call list.
Calling hours. Set the hours your practice contacts patients, in the patient's own time zone, and keep calls and texts inside them. State laws can set narrower windows than you expect, so check with your counsel.
Contact details. A wrong number or an old address wastes an attempt and can reach the wrong person.
The content. No more clinical detail than needed, and the practice name on every message.
Inbound coverage. Outreach creates callbacks. If nobody answers when patients ring back, the outreach fails at the last step. Our guide on how to stop missing patient calls covers that side.

How to tell whether outreach is working

Pick one number per outreach that matches the sentence you wrote at the start: patients who called back, patients who completed the visit, patients who confirmed their device arrived. Then look at which channel and which step reached them. If texts bring most of the replies, the call step can start later. If letters bring none, ask whether the addresses are current before you send more.

Review the outcomes your team recorded, not impressions. "We called everyone" and "we reached everyone" are different statements, and only the recorded outcomes tell you which one is true.

Frequently asked questions

Should we call or text patients first?

Text first when the patient only needs a fact or a small action and has agreed to texts. Call first when the patient needs to talk, decide or give consent. For a list of patients, a text followed by a call to those who did not respond uses staff time where it is needed.

Is it allowed to text patients about their care?

HIPAA permits texting patients, with the minimum necessary information. The TCPA adds consent and opt-out rules, especially for automated and marketing texts, and state laws can be stricter. Talk to your counsel about how they apply to your messages.

When should a practice send a letter instead of calling?

When the message is formal, such as a notice that a service has ended, when the patient has no mobile number or refused texts, or when the patient may want a copy to keep. Always include a phone number in the letter.

How many times should we try to reach a patient?

Set the limit before the outreach starts and write it down, then stop as soon as the patient responds or asks to stop. Spread attempts across different days and times, and record each outcome so the next person knows where things stand.
