Ada Health is a global health company offering digital health platforms that offer a unique and innovative approach to personalised healthcare. The company was founded in 2011, through the collaboration of Dr. Clair Novorol, Professor Martin Hirsch and Daniel Nathrath.

Ada Health is a leading provider of advanced artificial intelligence (AI) and machine learning tools, designed to empower individuals in managing their health and wellness. Their solutions cater to various collaborators, such as health systems, organisations, insurance companies, and other science firms. The company has a strong focus on patient-centered care, and improving human health through education and transforming understanding into better outcomes. The company has headquarters in Berlin, with offices in New York, London, and Toronto.

History

Ada was established in 2011 by Dr. Claire Novorol, Professor Martin Hirsch (an expert in artificial intelligence) and Daniel Nathrath (an entrepreneur). Dr. Novorol, a clinician in the UK's National Health Service, found inspiration for the company in clinical genetics, after successfully diagnosing a baby with a rare genetic condition through her searches in medical literature and scientific databses at Addenbrooke's Hospital, Cambridge. Upon realising the potential for digital tools to aid in faster and more accurate decision-making for doctors, she founded a digital health network for medical professionals called "Doctorpreneurs". It was through this network that she met her co-founders in Berlin. Ada's first product, "Ada DX" was originally a clinical decision support technology aimed at assisting doctors in accurately diagnosing rare diseases. The system used a Bayesian probabilistic reasoning system based on the medical history and differential diagnosis approaches used in clinical medicine. A doctor would input the patient's signs, symptoms, and findings, and the system would provide a ranked list of probabilistic conditions. A visual display would also indicate how each data point entered had contributed to the relative statistical weighting of the probably conditions suggested.

Medical Focus

In 2016 the business pivoted from supporting doctors directly to supporting patients experiencing a new health problem with a browser-based online tool and smartphone app, commonly referred to as a "symptom checker" called Assess. Users enter their demographics, medical history, and interact with a chatbot that asks them about the symptoms, timecourse, and severity of the problems they are experiencing. The Assess tool covers a broad range of potential patients, including children, pregnant people, those with mental health concerns, and the elderly. The probabilistic reasoning software supporting the software dynamically adjusts the questions asked to the user based on their previous answer, while also trying to ask as few questions as possible to prevent fatigue. This reasoning software is supported by a medical knowledge base built and reviewed by doctors that references the scientific medical literature, textbooks, regional epidemiology, disease models, and case reports including a range of several thousand common and rare diseases. At the end of their assessment the user is presented with a "triage" recommendation that suggests the level of urgency required and directs users to care options ranging from self-care at home to immediately seeking urgent care. In addition the app lists a number of "possible causes" that suggest medical conditions that might be causing the problem. Ada's software is available in Arabic, English (US and UK), Dutch, German, Italian, Spanish, Portuguese, Simplified Chinese, Swahili, Romanian, and French.[1]

In April 2023, Ada Health announced that Jefferson Health will implement its advanced technology system throughout its entire enterprise of 18 hospitas and over 50 outpatient facilities across Pennsylvania and New Jersey as part of a new initiative. The AI-powered symptom assessment and care navigation tool enables health systems to establish a strong digital front door, allowing healthcare staff members to devote more time to critical tasks rather than triaging patients or assisting them in navigating the care-seeking process. It additionally is said to offer patients the convenience of self-triaging their medical concerns, reducing unnecessary consultations and preventing patients from seeking care at the wrong service.

Regulatory Classification

Ada's product available to healthcare enterprise clients, and the Ada consumer app (i.e. downloadable from app stores) are both CE-certified Class IIa medical devices under the European Union's Medical Device Regulation (Regulation (EU) 2017/745, EU-MRR).[2][3] The company operates a quality management system certified under ISO 13485, and in the UK has passed UKCA marking assessment.

Media coverage

Ada has been compared to WebMD, Babylon's GP at Hand app, and Your.MD. In October 2017, when three apps were tested with symptoms from asthma, shingles, alcohol-related liver disease, and urinary tract infection, Ada performed very well; it asked about the most important symptoms and provided the best diagnoses. It produced diagrams showing which of the symptoms for each disease were present and the strength of the link, and a diagram of the percentage of people likely to have that diagnosis.

In September 2020, Broadband Commission for Sustainable Development issued a report identifying Ada as one of the AI solutions that have the "potential to address existing health inequalities and provide medical expertise to clinicians, health workers, and patients alike – all with the aim of improving the quality, access, and cost of healthcare delivery."

Rare diseases

A 2019 retrospective study evaluated Ada DX in rare disease diagnosis. Ada's top suggestion matched the confirmed diagnosis in 89% of cases (83 of 93 cases). In more than 56% of cases, Ada provided correct disease suggestions earlier than the time of clinical diagnosis. More than 33% of patients could have been identified as having a rare disease in the first documented clinical visit.

Reception

In 2020, the World Economic Forum awarded Ada and other 99 candidates as its "Technology Pioneers." Since its global launch in 2016, Ada has won several awards, such as App Promotion Summit's Fastest Growing App, Proddys Award for best Health and Fitness Product, CogX: Good Health and Well-being Award, German Brand Award, and German Innovation Award.
