My last few years

• Sep 2004: back to school

• Jun 2005: off to Tanzania

• Oct 2005: overland to Rwanda

• Since Jan 2006: bouncing around among Tanzania, Rwanda, South Africa and New York

Tanzania

MDH

• MDH= Muhimbili University + Dar Es Salaam + Harvard University.

• US government AIDS treatment program, currently about 25,000 HIV+ patients.

• Reason for going: they needed a new data person, because current was leaving.

MDH data capture

• Doctors fill in paper forms for each client visit• Carbonless copy goes to HQ for double-entry• Data stored in Microsoft Access• Processed in SAS to produce useful reports

– Patient monitoring– Program monitoring– External funders and government reports

Rwanda

Every situation different…

• Tanzania -> Rwanda• AIDS treatment -> Social Justice• Urban -> rural

• Rwinkwavu is now a functioning district hospital

Overall ICT Mission

• Develop and install OpenMRS:– An open source framework for medical record

systems in low-income regions– Reducess duplication of effort– Fast-growing collaborative effort– Installations in Kenya, Rwanda, Lesotho, Tanzania,

and Kenya– Join today! Come to meetings!

• Or come to Rwanda to teach Java. Contact Christian (callen@pih.org) or me for details.

ICT task: keep the internet running

ICT task: manage data collection

ICT task: satisfy reporting requests

Lab System

Hard to get on top of it!

• Hard to hold on, let alone make progress.

• Pulled in a lot of directions.

• Data quality a struggle• Data use a struggle• Might be close now...• Probably about to be the

national standard…

Tanzania 0.023 88 3826

Rwanda 0.025 51 2040

United States 1.629 6 3.69

Conclusion: The shortage of doctors and nurses requires that future expansion occur in rural clinics with most patient visits being managed by health workers with minimal training.

Plan

• Currently validating interface & protocol– Double blind study in top-notch hospital clinics– Revising questions after first round

• Next step: operationalizing system– Link to OpenMRS– Deploy in down-referral clinics– Remote supervision– Reports delivered to clinics

Integrated Management ofChildhood Illness (IMCI)

Potential benefits of point-of-care protocols

• More consistent and accurate use of protocols• More sophisticated and dynamic protocols• Easier to update• Less training• Improved supervision & monitoring• Data collection

Discussion

Some questions I don’t have answers to• Is there ‘real’ computer science to be done here?• Too much focus on health? What about water,

education, economics, etc?• How do we evaluate if these systems are worth their

cost?
