• Over 200 of the most common pediatric conditions were added to our medical content base. A part of them coincides with what previously functioned for adult users, with the difference in the insides - variations in the course of the disease depending on the age of the end-user were implemented. Newly added pediatrics conditions cover now over 90% of Global Burden of Diseases (GBD) listed for OECD countries.
• Along with the expansion of supported age groups, we changed the way that questions are asked. In pediatrics, those are designed to be answered by parents or caregivers on behalf of younger patients.
• A great number of unique symptoms and over 1,300 new medical concepts were created, tailored to meet the needs of children.
• The external physicians assessed the triage recommendations of pediatrics as safe in 96.7% of the cases.

Below, you will find a new batch of updates from Infermedica’s medical team:

• In the few upcoming releases, the medical team emphasizes stroke-related issues. This time, we have improved the hierarchy of Paresthesias for a more extensive neurological interview and enriched the symptomatology of Ataxia to differentiate between acute and chronic causes.
• We have reinstituted and improved the performance of diarrheal diseases associated with antibiotics - specifically Clostridium Difficile-associated diarrhea and Antibiotic-associated diarrhea.
• For more precise differentiation between laryngological conditions, from now on we inquire about the duration of Stuffed nose symptoms.
• Conditions like Baker’s cyst and Increased Intracranial Pressure were reviewed. More Triage Tuples were added.
• The prevalence and symptomatology of COVID-19 were rechecked and adjusted to the current epidemiological situation.

Model

Here comes the pack of updates prepared by Infermedica’s medical team:

• We have introduced Triage Tuples - pairs of symptoms or risk factors, which trigger a higher triage recommendation when they occur together in the interview. For example: Hypertension and Pregnancy, III trimester separately do not yield medical evaluation. Combined in one interview, however, they call for emergency care. All of the triage tuples are based on trusted triage protocols.
• The medical team has introduced the distinction between Viral Rhinosinusitis and Bacterial Rhinosinusitis for a more precise diagnosis, triage, and recommendation for the patient.
• We have enriched the interview regarding Vomiting. From now on, the engine will differentiate better between reasons for Chronic Vomiting and Acute Vomiting.
• Conditions like Hepatitis A, Hepatitis B, Hepatitis C, Primary Dysmenorrhea and Premenstrual Syndrome have been reviewed in accordance with the newest guidelines.
• Other minor reviews, guidelines checkups and bug fixes.

Model

Here comes the medical content update from Infermedica’s doctors!

• We have included COVID-19 into our main diagnostic engine. This means that diagnosing and triaging for COVID-19 will be possible not only on our dedicated COVID-19 Risk Assessment tool but also in our other solutions (Symptom Checker, Call Center Triage, and Chatbot).
• We keep expanding the collection of the conditions affecting teenagers: Multisystem inflammatory syndrome in children, Kawasaki disease, Flatfoot, Growing pains, Nocturnal enuresis, Vitamin A deficiency, Muscular dystrophy and Perthes disease.
• For more accurate triage, we started distinguishing between light rectal bleeding, commonly associated with hemorrhoidal disease, and severe rectal bleeding that demands a prompt medical evaluation.
• The medical team has created a question group regarding blood pressure, which has simplified and organized the information intake.
• Minor bug fixes and maintenance.

Model

Our medical team is working hard on the very special functionality of our diagnostic platform. The long-awaited update and introduction of triage tools for the pediatric population is coming soon. Stay tuned for the release date!

In the meantime, we want to present you with a couple of improvements to our medical knowledge base. Here are the essentials!

• We have implemented a system for the diagnosis of arrhythmias in the symptom checker. The team has introduced four new conditions, which will ensure a proper and safe triage recommendation for patients with heart rhythm problems:
  • Arrhythmia with a fast heart rate (Stable tachyarrhythmia)
  • Severe arrhythmia with a fast heart rate (Unstable tachyarrhythmia)
  • Arrhythmia with a slow heart rate (Stable bradyarrhythmia)
  • Severe arrhythmia with a slow heart rate (Unstable bradyarrhythmia)
• We are warming up for the introduction of the children's pre-diagnosis and triage functionality. We have reviewed and enriched our set of teenage-specific conditions. The prevalence and symptomatology of many diseases in this group have been double-checked. The team has also introduced a handful of new concepts specific for this age group, like Irregular menstruation in adolescence, Learning disability, and Frequent tobacco smoke exposure.
• We are adding complementary explanations to the most complex medical concepts, like health assessments. Our goal is to give users a broad context of the question, explain challenging medical concepts, and provide short instructions on performing some health assessments, such as measuring the heart rate.
• We continue to enrich our medical knowledge base with common health concerns. We have added Atypical Pneumonia to our set of respiratory conditions. Doctors have reviewed the risk factors associated with excessive alcohol consumption, along with Anaphylaxis and ACE-induced cough.

Model

During this pandemic, Infermedica is labouring hard making enhancements to its product line. Here’s what’s new!

• We have expanded the dyspnea division: Dyspnea, on exertion, Dyspnea, after a few minutes of walking, Dyspnea, at rest. This change allows for more accurate patient triage.
• Our urological database content has been improved and expanded. The medical team added Phimosis and Paraphimosis, and additionally reviewed Urethritis, Orchitis and Epididymitis, male and female infertility symptoms.

Model

We’ve just released a huge model update:

• We’ve edited hundreds of questions that are asked by the inference engine, making them more understandable for users.
• Current model contains new gynecological and traumatological conditions and symptoms.
• We are now better at recognizing and diagnosing headache episodes.

Model

Another technical release improving accuracy of our diagnostic model.

Model

A maintenance release that focused on improving underlying statistical models.

Model

First of all, we've refined underlying connections in the database. Other updates contain:

• New items called “metasymptoms”. When patients describe their symptoms they frequently use phrases like “body aches” or “stomach ache on the right side”. That’s why we’re introducing metasymptoms – observations that are not precise enough to be treated as proper symptoms. Metasymptoms, like symptoms, are available via /search and /parse, so you don't need to change your code.
• Another rearrangement of renal conditions.

Model

Learn about changes in Abdominal pain and more.

• We've improved the structure of symptoms related to a duration of abdominal pain. Now, the model is better at dealing with complexity of total duration and periods of pain. Besides, questions are simpler and more user-friendly.
• Abdominal pain has new child symptoms. They are related to the character of abdominal pain and its radiation to back.
• We’ve created Postpartum period as key risk factor for Postpartum depression.
• We've added Skin mass greater than 1 cm in diameter (parent symptom for three detailed types of lumps). We’ve removed other four skin-related symptoms.

Model

Hello in 2018! Let’s kick off the new year sharing some news.

• We’ve rearranged renal conditions and created new item called Acute kidney injury.
• We’ve added new symptoms: Edema, hip joint and Joint pain, during hip movement. As a result, we have improved hip conditions.
• We continue to simplify and rephrase difficult questions.

Model

The biggest change in this update is Physical injury – the new master risk factor. What do you need to know about it?

• Physical injury does not influence conditions probability, but it can make the interview more accurate.
• We recommend using Physical injury as a potential trigger for subsequent questions about injury-related risk factors.
• If Physical injury is set to present, it prompts a multiple-choice question about underlying risk factors.
• If Physical injury is set to absent, all injury-related risk factors are automatically set to absent too.
• All risk factors related to physical injuries are available on the Diagnosis page.

Other updates:

• We’ve added Tinea capitis condition together with its most typical symptom, Broken hair.
• We’ve replaced Red rings with light centers on skin with more specific Erythema migrans. As a result, we’ve created new parent symptom called Annular skin lesions.
• We continue to simplify symptoms related to dermatological changes.
• Tons of questions are now more user-friendly.

Model

We've refined medical concepts related to common injuries.

Model

We have introduced a few, but significant changes, including:

• We've added three new conditions, including Ruptured eardrum (together with Bleeding from ear as a typical symptom).
• We've removed Acute viral tonsillopharyngitis and Rotavirus infection. From now on, the API will return Acute pharyngitis and Gastroenteritis respectively.
• Now, you can handle the diffused abdominal pain with a new Abdominal pain, diffuse symptom.

Model

We've proofread, corrected and simplified the concepts' names and questions. Furthermore, new symptoms and conditions have been added. Finally, Dermatological changes, penis and Dermatological changes, vulva were merged into one: Dermatological changes, located in the genital area.

Model

We're exited to share with you hundreds of updates. Now, most of symptoms and many conditions are available in plain language (common_name field). In addition:

• We've added important valve disease.
• The endocrinological conditions were removed – because patients can't tell a difference between them.
• We've updated some dermatological symptoms. Now, patients should understand and distinguish them easily.
• We've removed abbreviations from the lab tests[beta]
  Lab tests are still in development and will be available soon.
