Your project - which I agree stretches across generations - is a great example of doing first and second generation work with a specific intention around potential interventions, and also applying the implementation lens to this work, especially as it applies to disproportionate burden on specific populations. This type of targeted approach is essential to ensure that advances in health care don't default to disproportionate benefit to those who already have the most resources.
I do agree that, even when planning an intervention to be used in a clinical context, it is essential to obtain information and input from community members and stakeholders outside the clinical world. It is often those groups and individuals who are either not accessing care at all or not accessing it al the moment that can provide insight into specific burdens and barriers to access.
