Computer science applications to improve health delivery in low-income countries. Neal Lesh
My Story
Mid-thirties computer researcher seeks more fulfilling career. Goes back to school then off to Africa. Discovers things are more simple and more complex than he originally imagined. Can't imagine doing anything else...

Simple Story “ We are the first generation that can end poverty. ” - Eveline Herfkens, UN Millennium Campaign
Complexity
Corruption, careerism, tax write-offs
5-star poverty alleviation meetings
Unintended consequences, e.g., paying volunteers
Imperialism & foreign experts
“ If you want to build a ship, don't drum up people to collect wood and don't assign them tasks and work, but rather teach them to long for the endless immensity of the sea.”
Antoine de Saint-Exupery
Information as Care
Study: rigorous application of standard treatment protocols reduced in-hospital mortality in children’s malaria cases by 50%
Clinician’s complaint: where are my lab results?!

Rural Dispensary in Tanzania

Standardized Care (IMCI)
Standardized Care (IMCI)
Tanzania: underfive mortality was 13% lower in the two IMCI districts Source: Schellenberg J et al Full IMCI in HF End of study 13% difference 95% CI: -7%, 30% Significant impact on stunting
Deploying IMCI
IMCI
Shown to reduce mortality and morbidity
Adopted by ~100 countries
But uptake not as good as hoped
Training expensive
Correct use tapers off over time
Supervision challenging
Why Automate IMCI?
Why Automate IMCI?
Improve adherence
Improve supervision
Easier to update
More sophisticated protocols
Reduced training
Field Work Results to be published in CHI’08
How Automate IMCI?
Exploratory Study
Pretesting & rapid iteration
Structured interviews
Observed trials w/ additional clinician to:
Ensure safety
Record adherence to IMCI
Record time
Viral Training
Key Findings
Must be
Fast
Flexible
Improve adherence to IMCI
Must address intentional deviation from IMCI
Temperature, respiratory rate
Advice
Adherence Results Investigation Current practice adherence e-IMCI adherence p-value Vomiting 66.7% (n=24) 85.7% (n=28) - Chest indrawing 75% (n=20) 94.4% (n=18) - Blood in stool 71.4% (n=7) 100% (n=3) - Measles in the last 3 months 55.6% (n=9) 95.2% (n=21) < 0.05 Tender ear 0% (n=1) 100% (n=5) - All 61% (n=299) 84.7% (n=359) < 0.01
