More attention, less repetition

The patient records the consultation in Ditto and receives a summary in plain language that can be shared securely. No action is required on your part.

Less repetition, more efficient consultations

Patients reread your explanation at home, leaving more room for new questions during the consultation.

The audio recording is locked in the app and cannot be shared

The recording is encrypted and remains locked in the app. Only the summary can be shared, and only securely.

The patient takes the lead

Ditto is the patient's modern notebook, and a listening ear for patients who attend alone.

Experiences from practice

  • Fewer questions during consultations

    Christian de Groot, GP and producer of the podcast De Innovatieve Huisarts

    “When I advise patients to take the Ditto app to a specialist, I know I will get fewer questions back in my own consulting room.”

    Fewer questions during consultations

    “When I advise patients to take the Ditto app to a specialist, I know I will get fewer questions back in my own consulting room.”

    The patient receives a clear summary of what was discussed. For the clinician, knowing that only 10% of the information is retained, the benefit is obvious.

  • Your voice stays secure in the app

    Bart Voorn, founder of Ditto

    “Everything is stored locally on the phone. That is a fairly radical choice: decentralised data storage in healthcare, right with the patient.”

    Your voice stays secure in the app

    “Everything is stored locally on the phone. That is a fairly radical choice: decentralised data storage in healthcare, right with the patient. The recording is locked in the app, but the Ditto summary can be shared straight away.”

    This is where Ditto differs from voice memos or dictaphones, where a single tap can put the entire conversation on social media.

Patients recording consultations

From recording and listening back to understanding, sharing and being prepared for what comes next.

Ditto

KNMG

Recording is permitted

A patient may record the consultation for private use, to listen back to later. Asking permission is appropriate but not required.

Ditto

A clear summary of the consultation

Ditto produces an understandable, validated summary, so the patient can review what was discussed at their own pace.

KNMG

Sharing publicly requires consent

  • A recording may not be made public without consent.
  • Standard recording apps offer immediate, unsecured sharing.

Ditto

The audio stays protected and encrypted

  • The audio is encrypted and stored only on the patient's own phone.
  • The audio cannot leave the app. The written summary can.

KNMG

Sharing concerns can help

Listening back or rereading together with loved ones helps the patient understand the information better.

Ditto

Loved ones stay involved

The summary can be shared with family or carers, so they can think along, and the patient does not have to repeat the same story each time.

KNMG

Clear communication shapes the consultation

Better transfer of information can lead to fewer or more focused follow-up questions. To this end, the KNMG encourages recording, among other measures.

Ditto

Well-prepared appointments

Ditto uses AI to suggest relevant questions, syncs with the patient's calendar and records follow-up appointments and tasks.

Apply your AI expertise for patients

Our research team works with academic medical centres to continuously evaluate the quality and safety of Ditto's AI.

A study of the safety and consistency of automatically generated medical summaries. In 1,010 pairwise comparisons by medical experts across 9 AI pipelines, Ditto scores best, with an 82% probability of winning (Bradley–Terry). Ditto also makes the fewest errors: 1.4% of summaries contained an inaccuracy, and none of these was clinically dangerous for patients.

Ditto in every consulting room

Patients at Ikazia Hospital can use the new Ditto app to remember their consultations better and reread them later, particularly when emotions run high or language is a barrier.

From Tuesday 30 June, Ikazia Hospital in Rotterdam-Zuid will help patients keep track of information with a new care innovation: the Ditto app.
“The fact that our technology is being introduced in consulting rooms across the hospital confirms that plain language is not an extra, but a condition for good care,”

More control for the patient

Using Ditto is entirely voluntary: patients decide for themselves whether to record their consultation, and the recordings and related data remain the patient's property. HartKliniek actively encourages its use through various patient communications, including the website, social media and QR codes in the waiting rooms and at reception.

“At HartKliniek, we stand for care that stays close to the patient, is transparent and always keeps a human scale. With Ditto, patients can now do this even more easily and reread information in full and in plain language. That strengthens communication between cardiologist and patient and makes for a pleasant, smooth process.”

Taking Ditto to the specialist

Stroomz advises patients to use Ditto when they are referred to hospital. The consultation with the specialist is recorded and turned into a summary in plain language, which the patient can calmly reread at home and share with loved ones. Use is entirely voluntary: patients decide for themselves whether to record, and the recording and summary remain theirs.

“When I saw it, I thought: this is actually very useful for patients, especially when the conversations are more complex. (...) When I advise patients to take the app to the specialist, I know I will also get fewer questions back in my own surgery.”

Official support for Ditto

The Dutch Patient Federation considers the development of new (AI) solutions that recognise the interests of patients to be of great importance.

Ditto fits the mission of informing patients better, helping them make decisions and supporting them with technology that suits the times. Ditto aligns well with the Federation's priority of shared decision-making: only when information is understandable can patients truly take part.
