Here comes one of the biggest updates of Infermedica’s medical content - we proudly present pediatrics content!

• From now on, our content is simultaneously developed for children of all ages and adults. The summarized number of medical concepts for pediatrics and adults is: 742+ conditions, 1362+ symptoms, and 150+ risk factors.
• 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 (opens in a new tab) of pediatrics as safe in 96.7% of the cases.

Please note, that pediatrics content is not included in already existing client contracts with Infermedica. Cost of implementing pediatrics content varies between our current and new customers.

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.

Soon, we’ll present the biggest update to our medical content – pediatrics content! That means this is the last time our Medical Content Update covers Adults only (+12yr) and our next changelog will be adjusted accordingly to better visualize the changes.

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.

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.

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.

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.

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.
