Data connectivity
• What is the minimum useful connectivity– Broadband?– 9600 baud?– 1000 bytes per day?

The case for SMS connectivity
• Cellular connectivity is reaching remote areas• Relatively low cost for 161 character messages– $0.00 to $0.20 per message
• Non cellular alternatives can be prohibitively expensive

NSDR 2010 6
The case for a facility based communication device
• Clinic ownership versus individual ownership– Charging and payments are key
• Communication appliance for dedicated applications– Avoid issues of keeping a PC running
• Integration with sensors• Secured to a fixed location• Potentially more reliable than a cell phone• Potentially better connectivity (with antenna or
improved cell phone radio)

Nicaragua Public Health System
• Health Post• Health Center• SILAIS• MINSA (Ministry of Health)
“Under resourced but functional and rational”

NSDR 2010 19
Power situation
• Grid power generally good– Has improved in recent years (help from Hugo)
• Power lost one evening during visit• Some health centers identified power as a
problem• Low voltage (should be 110)• Some sites recently added to the grid

NSDR 2010 20
Cell Phone Coverage• Two companies
– Claro– Movistar
• Claro has much broader coverage for rural areas
• Almost all health workers had phones
• Electricity may have wider distribution than cell phone coverage– Did not see any candidate
solar + cell phone sites

NSDR 2010 21
Health Post Connectivity
• Visit included moderately remote health posts.– All were close to cell phone connectivity, some on site,
some required a walk up the hill, at others reception depended on the quality of the phone
• Previously, Health Posts had radios, but these are being phased out where cell phones are available
• Communication from HP to HC often easier than communication from HC to HP
• Travel and visits another important communication mechanism

NSDR 2010 24
Cold chain
• 1350 refrigerators, including 250 solar. Kerosene refrigerators being phased out
• Vaccine distributed monthly in Pacific, once every three months in Caribbean
• Electric refrigerators considered reliable• Problems with solar refrigerators– Primarily with solar generation– Batteries the weak link

NSDR 2010 25
Cold chain reporting• Consistent recording of
temperature twice a day– WHO guideline
• SILAIS has a refrigerator technician– On call for repairs– Annual maintenance visits
• Vaccination data reported up from Health Posts
6/15/2010
![Page 26: SmartConnect : Data connectivity for peripheral health facilities](https://reader035.vdocuments.us/reader035/viewer/2022062815/5681694c550346895de0e7c7/html5/thumbnails/26.jpg)
NSDR 2010 26
Surveillance Reporting
• Reports on diseases and mortality• Daily or weekly from health post to health center
to SILAIS to MINSA• Submitted through different mechanisms– Phone, radio, hand delivery
• Commitment to accuracy at all levels– Quality control processes observed
• MINSA wanted more frequent reporting– Complained no data came in on weekends
6/15/2010
![Page 27: SmartConnect : Data connectivity for peripheral health facilities](https://reader035.vdocuments.us/reader035/viewer/2022062815/5681694c550346895de0e7c7/html5/thumbnails/27.jpg)
NSDR 2010 27
Use of surveillance data
• Data summarized at health center and above• Health centers and SILAIS generated statistics
and used them for evaluating programs and tracking results
6/15/2010
![Page 28: SmartConnect : Data connectivity for peripheral health facilities](https://reader035.vdocuments.us/reader035/viewer/2022062815/5681694c550346895de0e7c7/html5/thumbnails/28.jpg)
NSDR 2010 28
Information flows
• Surveillance data– From health posts to MINSA, collated at various levels
• Immunization– Twice daily temperature recording (reported???)– Vaccination numbers– Adverse reports, incidence reports on vaccination preventable
diseases• Pregnancy tracking– HP to HC only?
• Incidence reporting– PILOT Program: HC to SILAIS level

NSDR 2010 29
Requirements summary for Nicaragua
• Cell phone based communication device– Validated– Important to consider “marginal coverage”– Support for other radio communication would be valuable
• Target solar powered facilities with vaccination storage– Not validated– Relatively few solar powered facilities (and difficulties with
solar)– Electrical grid more widespread than solar – Possible need in Atlantic region

NSDR 2010 30
Requirements summary
• Vaccine refrigerator reporting– Validated– Paper based recording of temperatures at all clinics– District cold chain supervisors would benefit from the information
• Immediate repair• Identification / diagnosis of problem equipment
– Anecdotal cases of failure from clinic staff (attributed to power loss)
– Monitoring of up to five refrigerators would be helpful• Stock reporting
– Not validated– In person weekly visits adequate for collecting supplies

NSDR 2010 31
Requirements summary
• Surveillance reporting– Partially validated– Desire to speed up surveillance reporting– Reporting used at multiple levels– System design needs to get information to intermediate levels– User interface challenges in implementing this
• Incidence reporting– Not anticipated– Could be valuable to integrate this with existing cell phone solutions
• Lab diagnostics– Getting results to clinics can be very slow– Not clear which diagnostics are critical

NSDR 2010 32
Requirements summary
• General communication– Asymmetry in communication between levels– Pager for health posts– System must be considered in relation to cell phone
communication• Peripherals– Label printer could augment some of the processes– No use cases for bar code reading
• Telemedicine and consultation– No evidence of demand (although not a focus of the
investigation)

Design choices for SmartConnect
• Develop a device to pilot test within one year• Determine the value of a low bandwidth
facility based communication device• Create assets that could be turned into a
“product” in 2 to 3 years

NSDR 2010 37
Design options
• Use a low cost PC– Know difficulties of deploying PCs in this environment– Still need GSM connectivity
• Use a Smart Phone– Price too high– Difficult to pilot as a facility based device– Connecting external sensors is an issue
• Build a custom device• Base device on a low cost phone
– Use components of a phone– External device attached to phone - FoneAstra

NSDR 2010 39
Custom Device• Different design and packaging
model– Target a facility based device
• Easier integration and support of other hardware
• Superior cell phone radio (?)• Future components may be
cheaper• Possibility of an embedded
device• Support for other
communication technologies• Aim for compatibility with FA
on server side
FoneAstra• Lower cost
– Cell phone: $30– Telit 862: $100
• Leverage scale and professional engineering
• Integrated power source• Current version cannot
support control of the cell phone display– Does not support all
SmartConnect scenarios• We are planning to use FA
instead of SC for some scenarios
