Health

Lacuna Fund aims to close the gap in health disparities by fostering interdisciplinary collaborations that create, expand, or aggregate labeled training and evaluation datasets. Ultimately, the goal of this information is to help providers and patients make decisions that lead to more equitable healthcare outcomes.

The value of machine learning (ML) in healthcare is its ability to process huge datasets beyond the scope of human capability, and then reliably convert analysis of that data into insights that aid health professionals in planning and providing care, ultimately leading to better outcomes, lower costs of care, and increased patient satisfaction. [1] 

In many settings, particularly those that are low- and middle- income, ML is not utilized for healthcare, often due to the unavailability of datasets and a lack of infrastructure to support the implementation of ML applications. In addition, healthcare datasets often lack broad representation across demographic and socioeconomic groups. Therefore, where ML is utilized, the datasets that inform the algorithms supporting diagnosis and treatment risk being biased. Where data is representative, the data may also not be accurate, resulting in the incorrect understanding of differences across groups. Current data may also miss important socioeconomic, environmental, and other data that can determine health outcomes. Improvement of these datasets may improve ML models and ultimately, health outcomes across populations, from prevention, to diagnosis and treatment. [2]  

Additionally, Sexual, Reproductive and Maternal Health and Rights (SRMHR) are crucial for the health and survival of people across all genders, as well as to social and economic development. Well-designed SRMHR interventions have proven to be extremely cost-effective. However, the SRMHR of many people, particularly in LMICs, are far from realized. 

Lacuna Funding

Lacuna Fund supports dataset creation, aggregation, and maintenance for the training and evaluation of machine learning models to improve health datasets and outcomes in two tracks: 

  1. Addressing inequities in healthcare outcomes in the United States and in low- and middle-income contexts globally
  2. Improving Sexual, Reproductive, and Maternal Health and Rights in Africa 

Our Technical Advisory Panels (TAPs) are responsible for identifying data gaps, developing the Request for Proposals (RFP), and reviewing and selecting proposals. Our Racial Equity and Health Technical Advisory Committee identified needs for datasets that address health disparities in cancer, infectious disease, and chronic disease. 

In 2023, the SRMHR TAP seeks training and evaluation datasets that will improve SRMHR outcomes of populations in Africa. This call for proposals focuses on maternal and newborn health, family planning and contraception, sexually transmitted infections such as HIV/AIDS, diseases of the reproductive system such as prostate or cervix cancer, among other non-communicable diseases, and Sexual and Gender-Based Violence (SGBV). 

We seek datasets identified by local communities designed to address locally identified needs, so the following are illustrative examples only. The TAP and Lacuna Fund welcome proposals outside these topics: 

  • Question and answer datasets with high quality, evidence-based medical information validated by healthcare professionals, used to train chatbots, conversational agents and other applications focused on information provision.  
  •  Image datasets to train artificial intelligence and support   screening and diagnosis.  
  • Large population datasets (including longitudinal) such as maternal health datasets, civil registration and vital statistics, and longitudinal HIV datasets among others.  
  • Datasets representing the experience in the treatment process.  
  • In all datasets: gender-responsiveness and inclusion of key vulnerable groups 

The TAPs see great value in unlocking, augmenting, or aggregating existing datasets, as well as receiving proposals for new datasets.
