Send Texts to Patients Directly from Medesk

You can now send patients SMS messages with booking confirmations, appointment reminders, promotional offers and more straight from Medesk. Patient text messaging is one of the most effective tools available to modern practices, and with the right patient communication software in place, you can reach patients quickly, reduce missed appointments, and improve overall patient engagement.

Select from different patient subgroups based on age, patient tags and more to make your bulk messaging more personal and, of course, more effective.

You can also send texts directly from the Reports module if, for example, you want to show patients more information on the services they have paid for.

Our SMS integration means you never have to send appointment reminders manually again. Admin workload is greatly reduced and appointment attendance shoots up when reminders go out automatically at predefined times before visits. Naturally, this has an excellent effect on patient retention and loyalty to your clinic.

N.B. You should make sure that patients have consented to receive text messages for marketing and other such purposes before sending out bulk notifications.

Why Patient Text Messaging Works: The Evidence

Before exploring how to use SMS in your practice, it helps to understand why patient text messaging delivers such strong results.

SMS has a 98% open rate, compared to roughly 20% for email. The average text message is read within 90 seconds of delivery. For healthcare providers, this translates directly into fewer missed appointments, lower administrative costs, and stronger patient engagement at every stage of the care journey.

Missed appointments carry a significant financial and operational cost. Each missed hospital appointment costs the NHS approximately £160. For private clinics and GP practices, the impact is equally damaging. A well-timed missed appointment text reminder can reduce no-shows by a substantial margin, with studies suggesting automated reminders cut DNA (did not attend) rates by up to 38%.

Beyond the numbers, patients simply prefer to hear from their practice by text. It is fast, convenient, and does not require them to pick up the phone or log into a portal. When practices invest in reliable patient communication software, they create a measurable improvement in both attendance and patient satisfaction.

Patient Consent, GDPR, and Data Protection

GDPR Patient Text Messages: What You Need to Know

Sending text messages to patients is subject to UK GDPR and the Data Protection Act 2018. As a data controller, your practice is responsible for ensuring that personal information is processed lawfully, fairly, and transparently. This applies to every message you send, whether it is a routine appointment reminder or a bulk promotional campaign.

The key principle to understand is that providing a mobile phone number is not consent. A patient who gives you their number at registration has not automatically agreed to receive texts. For direct care messages (such as appointment confirmations and clinical reminders), you may be able to rely on a legitimate interest or public task basis, depending on your organisation type. For marketing messages, including promotional offers and service announcements, explicit consent is required.

Consent must be:

• Freely given, specific, and informed
• Recorded clearly in the patient record
• Easy for the patient to withdraw at any time

Your privacy notice should tell patients what types of messages they may receive, which channels you use, and how they can update their preferences. This information should be readily accessible, not buried in lengthy terms and conditions.

Clinical text messaging introduces additional considerations. Sending sensitive clinical information, such as test results, diagnoses, or medication details, via SMS carries inherent risk and should only be done where patients have specifically agreed to receive such information this way and where the content does not place them at risk if the message is seen by a third party.

When using Medesk to send bulk messages, the built-in consent note serves as an important reminder: always confirm that patients have opted in before sending marketing or non-essential communications.

Confidentiality and Security Considerations

Text messaging is convenient, but it is not without risk. Practices using SMS to communicate with patients should be aware of several confidentiality vulnerabilities that are easy to overlook.

Shared and family devices. Many patients, particularly older adults and younger children, share mobile devices with family members or carers. A message about an appointment or health condition may be read by someone other than the intended recipient. Where possible, ask patients at registration whether their mobile number is shared.

Stolen or lost phones. If a patient's phone is stolen, any messages in their inbox become accessible to whoever has the device. This is a particular concern if the message contains any identifiable clinical information.

Outdated contact details. Sending a message to a number that has since been reassigned to a different person is a data breach. Practices should have a process for regularly verifying and updating patient contact information, ideally at every appointment or registration event.

Screen previews and notifications. Even a locked phone will often display the first line of a text message as a notification. Avoid including sensitive details in the opening line of any patient message.

To reduce these risks, keep message content as general as possible unless the patient has specifically consented to receive clinical detail via SMS. Use your patient communication software to flag records where contact details have not been verified recently, and ensure that your staff are trained on the appropriate content for patient text messages.

Best Practices for Writing Patient Text Messages

The quality of your patient messages matters as much as the timing. A poorly written text can confuse patients, undermine trust, or fail to prompt the action you need. The following principles will help your team write effective, professional messages.

Keep it short and clear. SMS messages should ideally stay under 160 characters. Even where longer messages are possible, brevity improves readability. State the key information first: who the message is from, what action is needed, and when.

Use plain language. Avoid clinical jargon or abbreviations that patients may not understand. Write as you would speak to a patient face to face: clearly, respectfully, and without unnecessary complexity.

Always identify the sender. Patients are increasingly wary of unknown senders. Include your practice name at the start or end of every message so the patient knows immediately who is contacting them.

Include a clear call to action. If you want a patient to confirm an appointment, reply with a specific word or visit a link. Make it obvious what you need them to do.

Do not send clinical results via SMS. This is a common error. Standard SMS is not a secure channel for sensitive clinical information. Test results, diagnoses, and medication changes should be communicated through secure portals, phone calls, or in-person consultations, unless specific consent and appropriate safeguards are in place.

Avoid sending messages at unsociable hours. Schedule messages to arrive during reasonable daytime hours. Early morning or late evening messages can cause unnecessary anxiety.

Proofread before sending. Bulk messages cannot be recalled. A typo in a patient's name or an incorrect date creates confusion and damages your practice's credibility.

Common Use Cases: What to Text Your Patients

Appointment Reminders and Missed Appointment Text Reminders

Appointment reminders are the most common use case for patient SMS. Sending a reminder 48 hours before a scheduled visit, followed by a second reminder on the morning of the appointment, has a proven impact on attendance. A missed appointment text reminder sent immediately after a DNA can also open a dialogue and help the patient rebook promptly.

Example message: "Reminder from [Practice Name]: You have an appointment on [date] at [time] with [clinician]. Reply CONFIRM to confirm or call us on [number] to rearrange."

Prescription and Medication Notifications

Notifying patients when a repeat prescription is ready for collection, or when a medication review is due, reduces unnecessary phone calls to reception and keeps patients on track with their treatment.

Vaccination and Screening Invitations

Bulk SMS is highly effective for population-level campaigns such as flu vaccination invites, cervical screening reminders, and bowel cancer screening follow-ups. Using Medesk's patient subgroup filtering, you can target the right age groups and demographics without manually building lists.

Follow-Up Care Messages

Post-appointment follow-up texts can check in on a patient's recovery, remind them to complete a course of medication, or prompt them to book a follow-up consultation. These messages support continuity of care and improve patient engagement without requiring clinical staff time.

Patient Satisfaction Surveys

Sending a short survey link after an appointment is a low-effort way to collect feedback and monitor patient experience. SMS survey response rates are significantly higher than email equivalents.

Practice Updates and Health Campaigns

Informing patients about changes to opening hours, new services, or seasonal health campaigns (such as mental health awareness or diabetes prevention) keeps your patient list engaged and informed throughout the year.

Handling Patient Opt-Outs and Contact Preferences

Patient SMS Opt Out: Managing It in Practice

Every patient has the right to object to receiving communications by SMS, and your practice must be able to honour that request quickly and reliably. Patient SMS opt out is not simply a courtesy: under UK GDPR, individuals have specific rights regarding how their data is used for direct communications, and failure to act on an opt-out request promptly can constitute a breach.

In practical terms, your opt-out process should include:

• A clear reply keyword (such as STOP) included in bulk messages
• A process for logging opt-outs in the patient record the same day
• A check against the opt-out list before any bulk send is initiated
• Separate preference settings for different message types (marketing versus clinical reminders)

Medesk allows you to record patient communication preferences directly within the practice management system, so your team can see at a glance whether a patient has consented to SMS, opted out of marketing, or requested contact by a specific channel only. This reduces the risk of sending messages to patients who have withdrawn consent.

It is also good practice to give patients the opportunity to update their preferences at each visit, and to review your consent records periodically to ensure they remain current.

Beyond SMS: Multi-Channel Patient Messaging

SMS remains the most reliable channel for reaching patients quickly, but a multi-channel approach improves your ability to connect with different patient groups on the channels they prefer.

WhatsApp is increasingly popular for patient communication, particularly among younger patients. It supports read receipts, rich media, and two-way texting with patients, which allows practices to have genuine conversations rather than simply broadcasting one-way notifications. Two-way texting patients opens up new possibilities for triage, appointment booking, and follow-up queries.

Email remains appropriate for longer, more detailed communications such as pre-appointment instructions, referral information, or post-consultation summaries. It is not suitable for time-sensitive messages due to lower and slower open rates.

The NHS App (for NHS-connected organisations) provides a secure, verified messaging channel directly to patients who have registered. It is particularly well suited to clinical communications where security is a priority.

RCS (Rich Communication Services) is an emerging channel that sits between standard SMS and WhatsApp in terms of capability. It supports branded messages, images, and interactive buttons within the native messaging app, without requiring the patient to install a third-party application.

The most effective approach is to use your patient communication software to manage all channels from a single platform, ensuring consistent messaging and complete preference records regardless of the channel used.

Automating Patient Messaging Workflows

One of the most significant efficiency gains available to modern practices is the automation of routine patient messaging. Rather than relying on administrative staff to manually send reminders or follow-ups, automated workflows trigger messages at predefined points based on appointment schedules, patient actions, or clinical milestones.

With Medesk, you can configure automated messages to send at specific intervals before an appointment: for example, a booking confirmation immediately on scheduling, a reminder at 48 hours, and a final reminder on the morning of the visit. This requires no manual intervention once the workflow is set up.

Automation can also be triggered by patient actions. If a patient cancels an appointment, an automated message can invite them to rebook. If a patient has not responded to a recall invitation after a set number of days, a follow-up message can be sent automatically.

The benefits of automation extend beyond convenience. Automated workflows are consistent: every patient receives the same well-written, correctly timed message, regardless of how busy the reception team is on any given day. This consistency improves patient engagement and ensures that no patient falls through the gaps due to an oversight.

When setting up automated workflows, review the message content and timing periodically to ensure they remain accurate and appropriate. An automated message referencing outdated opening hours or an old phone number can create confusion and undermine patient trust.

Frequently Asked Questions

1. Does giving a practice their mobile number count as consent to receive texts?

No. Providing a phone number at registration is not consent to receive text messages. Patients must actively agree to be contacted by SMS, with that agreement clearly documented in their record. This is a requirement under UK GDPR, and it applies whether the message is a routine reminder or a marketing communication.

2. Can clinical results be sent by text message?

In most cases, sending clinical results via standard SMS is not recommended. SMS is not an encrypted channel and messages can be read by anyone with access to the patient's phone. Results should be communicated through secure, verified channels unless the patient has specifically requested SMS delivery and the clinical risk has been assessed as acceptable.

3. How should practices handle text messages sent to children or young people?

Where the patient is a child, messages should normally be directed to the parent or guardian unless the young person is assessed as Gillick competent and has requested direct contact. Care should be taken to avoid disclosing sensitive information (such as sexual health or mental health services) to a parent or carer without the young person's knowledge and agreement.

4. What is patient SMS opt out and how do I manage it?

Patient SMS opt out is the process by which a patient withdraws their consent to receive text messages. Practices must act on opt-out requests promptly, record them in the patient's record, and check opt-out status before any bulk send. Including a clear STOP reply option in every bulk message is a practical way to manage this at scale.

5. What is the difference between one-way and two-way texting patients?

One-way messaging means the practice sends texts but patients cannot reply. Two-way texting patients allows replies, enabling patients to confirm appointments, ask questions, or request callbacks. Two-way messaging requires a system capable of receiving and routing responses, and a process for staff to monitor and act on incoming messages in a timely way.

Medesk brings together automated reminders, bulk messaging, subgroup targeting, and reporting in one integrated patient communication software platform. Whether you are sending a single missed appointment text reminder or a vaccination campaign to thousands of patients, Medesk gives your team the tools to communicate effectively, compliantly, and without adding to the administrative burden.
