Supplementary File – Unmet Clinical Needs Appendix: Modifications made to the process and their respective rationale Category AIM Modification Rationale Mindset To train a multidisciplinary team of engineers, designers, business graduates and clinicians with an intention to form start-up companies that solve a clinically validated need with a solution that fits the Indian healthcare system. Innovative solutions for unmet needs require to reach the patient in order to reduce the burden of the problem and by developing the solution through a start-up company increases the chances for commercialization of the product to bring it into the market. Team Structure Clinical fellows are internal to the hospital facilitating the clinical immersion. In India, the ecosystem for MedTech innovation is still in its infancy and most clinicians do not recognize this space to be a sustainable career options. Many clinicians do not wish to take the risk of jeopardizing their clinical careers while exploring medical device development through a fellowship program. But, these clinicians are invaluable as they can provide integrated observations that cannot be obtained by shadowing. Pre Immersion Three week classroom training before immersion that includes in-depth understanding of the process from selecting a focus area to commercialization of a product. Additionally, it includes basic clinical background in the focus area and ethics. It is critical that the observations are performed while keeping in mind the information that will be required in different stages of the process. This instruction is important as it helps avoid future situations in which the team must backtrack due to lack of information. Clinical Observation The team records negative outcomes only and documents the information collected into a 15 parameter observation docket: date/time venue, a detailed account of the observation ( 100-150 words), the negative outcome, the problem statement, the need statement, criticality of the need as felt by the clinician, frequency of the negative outcome as seen by clinician, criticality of the need as felt by the observer, frequency of the negative outcome as seen by the observer, the best available solution, cost of the existing solution, incidence/prevalence data, patient pathway, and any relevant insights. Observers often record observations in which they see a potential for something to go wrong but nothing actually goes wrong. These observers jump straight to potential solutions without fully considering the pre-existing landscape. To avoid this, we train the team to record observations where there was a negative outcome seen so that a solution is created for a problem that actually exists. In addition, there is a huge shortage of epidemiological, cost, and demographical data that is accurate and reliable. Such data is needed for the filtering process. For most needs such information is not easily available and this affects the filtering process. To tackle this issue we train the team to collect information from clinicians as the observation takes place and carry out voice of customer studies to get some data that can be used later to make calculated extrapolations or check the reliability of available data. Needs Filtering A set of filtering parameters designed to identify unmet needs that have high criticality and frequency. These needs must also have a high market impact if addressed, moderate predicate competition, moderate technical complexity, low regulatory hurdles and a good buyer environment. We designed 4 sets of filtering levels that evaluate needs using a prestructured scoring system and a standard weighting formula. This filtering system takes into account all the parameters that need to be favorable for the solution to increase the chance of its development and implementation into our healthcare system. On arriving at the top 10 needs, the teams are trained to select their top 2-3 needs based on an in-depth stakeholder and business model understanding.
