Health link - OceanDAO Round 11

Name of Project: [Health link] MVP for data onboarding funnel to bring primary care data on-chain into OCEAN

Category : Existing project (Category 2) – A “Build” project to develop a user onboarding funnel prototype for a dApp that aims to use Ocean to tokenise health data.

Fundamental metrics : Data-token contracts

One-sentence summary :
A grant is requested to build a software prototype for a dApp that aims to use Ocean to tokenise primary care data through a pilot with an existing community of doctors engaged through the previous grant. This project seeks to leverage OCEAN in bringing healthcare data on-chain and accrue value to end-users such as patients and healthcare providers, who are excluded from the traditional healthcare data economy despite being the primary contributors of this data.

Description of the project background:

This project seeks to develop a minimum viable product (MVP) for a pilot with the community of doctors engaged through the 1st Healthlink Ocean DAO grant. Our aim is to unlock healthcare data in order to drive discoveries of new treatments and democratize participation in the healthcare data economy for all end-users, including patients and allied healthcare providers themselves (Nurses, Dieticians, etc). Further details and background to the problem being solved have been described in the previous application.

The core study findings from the initial review (deliverable 1 from the previous proposal) have been published at this link. These findings are translated in the form of the proposed product to address the public health gaps that have been identified and address the shortcomings of existing solution. We utilise an agile approach to align with the new format and scope of Ocean DAO grants, and have planned the scope of this grant application accordingly. We aim to develop an MVP and conduct an early pilot with primary care practitioners to ensure the alignment of user journeys with existing clinical pathways for ease of adoption, as well as to assist the development team in prioritizing the development of subsequent modules (data request board, front-end UI to facilitate contribution of tokenized data into the Ocean marketplace, etc).

Please find a summary below, and a description of how the activities funded in the previous grant have facilitated the conceptualization of the product. We have uploaded a mock-up of the minimum viable product (MVP) of our intended dApp and embedded it in this video to highlight the targeted user journeys for initial user and data onboarding and exchange.

Description of the problem:

In the course of literature review, it was found that all existing relevant reports were in early stage of technology readiness, whereby most solutions did not have primary clinical validation data involving patients. These are illustrated in the 3-category breakdown of (1) Technical design description, (2) Technical demonstration, and (3) Clinical translation (mostly cross-sectional descriptions) depicted in Figure 3.

Electronic health records (EHR) were the leading public health application of blockchain described in the literature published by many previous researchers from different countries (Figure 4 of the publication). EHR applications of blockchain have had a steady 70% year-on-year increase in publications. Yet, few progressed to the clinical translation/ implementation stage, and appear to have been lost in the “chasm” of the technology adoption life cycle (TALC). We posit that this is due to the enterprise (B2B) nature of the offerings of the products in the reviewed studies, resulting in privacy concerns due to lack of patient consent in the sharing/custody of data by 3rd party organisations. That said, the only 1 study of such a program that obtained patients feedback found that they indicated strong interest in a patient health record product, particularly 1 that gives them greater visibility over their health record with notifications regarding any updates that are made.

The findings from this research have validated the clinical need identified in multiple countries/regions as well as the user demand for a digital health record product that gives patients greater access and control over their data. It has also identified various other avenues of horizontal service expansion (such as drug/medical device supply chain monitoring, medical device/IoT data integrations, etc) that can integrate with the digital health record product as the initial platform dApp offering for vertical penetration into the healthcare industry.

Description of the solution:

Therefore, we formulated a strategy to develop a crypto-native personal health record (PHR) product that addresses the clinical needs for secure and trustless health data custody and sharing. This is embodied by the primary offering for consumers (B2C) that incorporates patient consent for any health data accession, annotation, or sharing, in order to address prevailing privacy concerns. This is the necessary initial ground work for the onboarding funnel for data that can subsequently be tokenized in future modules in a model for financializing health data that incorporates individual consent. Future modules will incorporate staking functionalities for patients to deposit their tokenised health data to earn a yield via the OCEAN data marketplace from interested payers (e.g. pharmaceutical companies requesting health data for research) opening up enterprise (B2B) offerings for health data commercialisation.

Grant deliverables:

  • 1) Development sprint to code a clinician user and data onboarding funnel illustrated here.

  • 2) Pilot with primary care providers to explore alignment with existing clinical practice, measures required to facilitate adoption, and pre-populate an interested list of early adopters for the product.

How the project drives value

The end-goal at the end of 9-12 months is to increase total number of OCEAN data token contracts and consuming volume by conceiving a clinically-sound approach and onboarding ramp for healthcare data into the OCEAN data economy with participation from an active community of practicing clinicians with private practices that can independently participate without the bureaucracy of larger traditional healthcare organisations.

Summary of Project updates:

Deliverable 1 - Development sprint to code a clinician user and data onboarding funnel - completed. This MVP has been tested (results below) during a soft launch with attending physicians for the PCGC medical conference organised with Ocean. 48 individuals out of all attendees had participated in the pilot, among whom 37 agreed to complete a post-pilot survey. Summative feedback is summarised below, with qualitative feedback regarding onboarding process and alignment with varied clinical workflows is currently being incorporated in the prototype before our 2nd pilot with interested doctors. The engagements during and since the conference have given rise to several working groups of allied health, GP and specialist doctor attendees in collaboration with Healthlink to develop a series of healthcare data modules to tokenise various forms of primary care healthcare data to be published into the Ocean marketplace. These various modules will be integrated into this onboarding funnel, with the first such module being described here.

Deliverable 2 - Pilot with primary care providers to explore alignment with existing clinical practice, measures required to facilitate adoption, and pre-populate an interested list of early adopters for the product. - In progress: We have completed the pilot for user-acceptance testing (UAT) with willing attendees during the PCGC medical conference. Out of 48 participants in the UAT, 37 agreed to complete a post-pilot web-based survey giving a healthy response rate of 77%. This was disseminated through invite link as well as post-conference marketing materials to attendees - screenshot below:

Responses were overall positive with 89% of participating clinicians indicating that the conference has helped improve their understanding of web 3.0 blockchain, NFT or the metaverse. Moreover, 81% of participating clinicians indicated that they would be interested to adopt health-related web 3.0 blockchain, NFT or metaverse applications for their patients.

[Deliverable update]

[X] Completed prototyping of MVP for pilot soft-launch at the PCGC medical conference organised with Ocean.
[X] Completed - Completed pilot with UAT, summative results above and qualitative results/ feedback currently being incorporated into the prototype. Due to large amount of feedback/changes, we are looking to conduct a second pilot with the interested clinicians before finalising the MVP into the published application. In tandem with the recruitment/engagement efforts for this pilot, we aim to engage interested clinicians to highlight our next planned module for patient self-directed chronic disease data aggregation to identify interested clinicians for pilot of that module with their patients.


Thanks for the updates. Cheers.
