What are the opportunities and risks of deploying AI in digital health care?

Background: Ethical biometrics for the ‘last mile’

AI is great… for white males

Opportunity: Incredible access to dataRisk: Incredible breaches of privacy

Opportunity: Truly customized technologyRisk: Vendor lock-in / no interoperability

Conclusion: For every complex problem there is an answer

that is clear, simple, and wrong

1. Learning vs. bias

1. Mass data vs. privacy

1. Customization vs. openness

Discussion:

Bridging the gap of data collection and analytics

Dr Anuraj Shankar, Senior Research Scientist, Harvard T.H. Chan School of Public Health

Open Smart Register Platform

www.smartregister.org

OpenSRP is a scalable Open-source Smart Register Platform that enables FHWs

to digitally register and track the health of all their patients through a single,

user-friendly mobile/tablet application, adaptable to different use cases.

AH Shankar, AI and ML in Health Programs 11 |

Challenges for AI and ML in Public Health

Use case is not clear

The right data is not collected

Assumption that AI/ML can ”clean up” bad data

The “Human Gap”

– Supervisors do not understand the analysis

– Workers don’t trust the conclusions

“Humans help humans, technology is simply a tool”

Case study:

Optimize use of screening data to improve efficiency of

community health workers to detect tuberculosis cases

▪ cough

▪ fever

▪ haemoptysis

▪ night sweats

▪ weight loss

▪ fatigue

▪ shortness of breath

▪ chest pain

▪ diabetes

▪ family diabetes

▪ TB exposure

▪ kidney failure

▪ asthma

▪ COPD

▪ HIV

▪ active smoker

Implications of the analysis for active TB screening

Increasing the specificity by 20% or more, by considering clinic

location, means saving more money and time from doing

unnecessary tests.

This can be achieved without losing any sick people in the

screening process.

OpenSRP Indonesia cross-cadre data sharing:

enables system wide AI/ML analysis

AH Shankar, AI and ML in Health Programs 16 |

Indonesia – OpenSRP

AI/ML to improve client-centric care

Increase workforce productivity by

identifying incorrect or bogus data,

assess predictors of worker

productivity and client outcomes,

identify ways to improve

coordination among health

workers.

Increase client health by identifying

specific client care seeking

patterns and tendencies. Assessing

what types of interactions are

effective, what locations are high

risk

Discussion:

How is CRS using AI and machine learning in global programs?

Results: High confidence predictions of those at greatest risk are available 1-2 months in advance. Early warning information is continuously shared with communities to help them plan and target responses.

Solution: A low burden, high frequency data collection protocol gathers information about shocks, household characteristics, and food security. Machine learning algorithms identify predictors of food insecurity and examine household resilience.

Problem: The increased severity of natural disasters exacerbates food insecurity. Severe floods in 2015 followed by drought displaced hundreds of thousands in Malawi. The ability to respond to shocks varies significantly by household. Resilience is difficult to measure or predict.

Discussion:

What are the key questions you should ask yourself before starting an AI-based initiative? What are the small things you can do to make a difference?
