CASE STUDY SERIES ON ICT-ENABLED DEVELOPMENT: AFRICA
An initiative of IICD and bridges.org
The bridges.org/IICD Case Study Series on ICT-Enabled Development sets out
to illustrate how ICT contributes to development in Africa. The aim of this
series is to help ground level initiatives imagine the possibilities of
what can happen if they use ICT successfully to overcome development
obstacles, and to contribute to the existing body of knowledge on the
digital divide. For more information about the case study series, go to:

CASE STUDY: The Compliance Service uses SMS technology for TB treatment
I. Overview
Initiative: Dr. David Green's Compliance Service uses the Short Message
Service (SMS) to alert tuberculosis (TB) patients to take their medication.
The initiative has led to a significant increase in the recovery rate of
patients and could lead to savings for healthcare authorities.
Implemented by: Dr. David Green, a qualified medical practitioner and
consultant in Cape Town, South Africa, through his company The Compliance
Service.
Field: Healthcare.
Funding or financial model: Commercially driven. A pilot project has been
sponsored by the City Council of Cape Town.
Timeframe: Started in 2002.
Local context: The population of Cape Town is divided along race and class
lines. White people generally have access to middle and high-income jobs,
good municipal services, and private healthcare, and they can afford
comfortable housing. Coloured, and especially black citizens of Cape Town
generally have low paid jobs or are unemployed, live in informal
settlements where housing is often substandard, cannot rely on good
municipal services, and have to use the overburdened public healthcare
system. Cape Town's Mediterranean winters are cold and wet, and this poses
an additional health hazard for people living in informal settlements.
Large areas of these settlements are built below the waterline and are
flooded during the winter months. Due to this combination of factors, poor
black people are more prone to contracting TB. Unemployment countrywide is
estimated at 41.5% and the GDP per capita is estimated at USD $8,500.

The development problem/obstacle addressed: Cape Town has one of the
world's highest incidences of TB, largely due to socio-economic and
climatic factors. TB patients must strictly follow a difficult drug regime
-- four tablets five times a week for six months -- and they often forget
to take their medication. Non-compliance with the drug treatment has
exacerbated the high occurrence of TB and has created difficulties for the
local, overburdened healthcare service. Precious medicines are wasted when
people do not take their medication on schedule, and non-compliance causes
the TB virus to become increasingly drug resistant.
How ICT is used to overcome the problem: Evidence suggests that TB patients
often do not take their medication simply because they forget. So, Dr.
Green uses SMS (Short Messaging Service) -- a text message service that
enables short messages of up to 160 characters to be transmitted between
cell phones -- to alert patients to take their medication.
Healthcare professional were skeptical whether the uptake of cell phone
technology was high enough to justify the project. However, Dr. Green found
that over 50% of people in the Cape Peninsula had access to cell phones. At
the clinic where the pilot study was conducted, 71% of TB patients had
access to a cell phone.
Dr. Green enters the names of TB patients onto a database. Every half an
hour his computer server reads the database and sends personalised messages
to the patients, reminding them to take their medication. The technology
that he uses to send out the messages is extremely low-cost and robust: an
open source software operating system, web server, mail transport agent,
applications, and a database. Currently Dr. Green charges the City of Cape
Town R11.80 per patient per month to send out SMS messages.
Initially the SMS message sent to patients read: "Take your Rifafour now."
When patients complained about the boring message, Dr. Green sent them a
variety of alerts, including jokes and lifestyle tips with the result that
he now has as database of over 800 messages that he changes on a daily
basis. Of the 138 patients involved in the pilot, there was only one
treatment failure.
Next steps: The World Health Organisation has cited the project as an
example of "international best practice". The City Council of Cape Town has
decided to extend the pilot project to other City clinics where the cell
phone ownership of patients are high, while the South African Government is
considering the technology for nationwide use. The system is also being
investigated for use with HIV treatment.
Geographical area targeted: Currently Cape Town, South Africa, with the
potential for future expansion across South Africa.

II. Gauging Real Impact
Has this use of SMS messaging in the treatment of TB had a Real Impact at
ground level? How does it compare to the best practices established by
other successful initiatives? We used bridges.org's 7 Habits of Highly
Effective ICT-Enabled Development Initiatives as a framework to highlight
what this initiative has done well.
1. Implement and disseminate best practice. Dr. Green did a lot of
research on compliance and adherence to medicine while doing his PhD in
Pharmacology which led him to the insights on which this project is based.
2. Ensure ownership, get local buy-in, find a champion. Dr. Green convinced
the City of Cape Town's health directory to run a pilot at one of the
City's clinics and so spurred on the public use of his technology, instead
of selling the service to private doctors. He ensured buy-in from patients
by acting on their feedback.
3. Do a needs assessment. Dr. Green was aware of the need for interventions
that increase TB medication adherence, and especially so in Cape Town,
which has one of the highest rates of TB infection in the world.
4. Set concrete goals and take small achievable steps. Dr. Green first
tested the reminder messages on his mother to take her hypertension
medication. He then convinced the City of Cape Town to run a pilot at one
clinic. On the back of that success a Randomised Control Trial has been
launched, involving South Africa's Medical Research Council (MRC), the
University of Cape Town (UCT) and Dr. Green.
5. Critically evaluate efforts, report back to clients and supporters, and
be prepared to adapt. MRC and UCT are providing a critical, independent
review of the pilot project. The outcome of the trial will be published in
four research papers that will be subject to peer review.
6. Address key external challenges. The biggest external challenge that Dr.
Green had to face was the preconceived ideas of health professionals
regarding the uptake of cell phone technology in Cape Town.
7. Make it sustainable. Dr. Green's company, The Compliance Service, is
based at the UUNET Bandwidth Barn which provides small IT businesses with
affordable office rentals, shared office facilities, and reduced Internet
connectivity costs. He deliberately kept the price of his service low so
that more people can use and benefit from the technology. His choice of
technology has enabled him to provide his service at a very affordable price.
III. The Story
A Cape Town doctor has dramatically helped the fight against tuberculosis
(TB) by introducing a SMS service to remind patients to take their medication.
Dr. David Green, a consultant in Managed Care, Disease Management and
Information Systems, became so frustrated when his mother constantly forgot
to take her medication for hypertension, that he started sending her SMS
reminders -- and it worked. Thanks to research he did for his PhD in
Pharmacology, he was able to take his idea further and apply it to public
healthcare. Dr. Green's reading eventually led him to two important
insights. Firstly, he concluded that interventions designed to prevent
non-compliance of treatment was not effective because it was applied
indiscriminately. He concluded it was necessary to identify those patients
who were non-compliant and find out why they were not taking their
medication. Secondly, he was struck by the overwhelming literary evidence
that suggested people were not taking their medication simply because they
forgot.
It did not take him long to make the connection between the effectiveness
that his SMS messages had on alerting his mother, the high incidence of TB
in Cape Town, and the possibilities that bulk SMS messages could present.
However, when he wanted to pilot his innovative idea with TB patients at a
local clinic in Cape Town, he met with resistance. Healthcare professionals
were skeptical about the number of patients who would have access to cell
phones. Not deterred, Dr. Green went back, did research and persuaded them
with statistics which indicated that over 50% of Cape Town residents have
cell phones. In addition, he found that 71% of patients at the clinic he
earmarked for the pilot had access to cell phones. The local health
authority eventually agreed and paid R11.80 per patient per month to run
the SMS reminder service. The results of the pilot have been outstanding:
of the 138 patients involved in the pilot, there was only one treatment
failure.
The Medical Research Council of South Africa and the University of Cape
Town has now embarked on a Randomised Control Trial to compare the
cost-effectiveness of the SMS-reminder service against the cost of
non-compliance to TB treatment. In the mean time, the pilot has been so
successful that the World Health Organisation has singled it out as example
of "Best Practice".
The initiative not only uses technology to address a real need effectively,
but it does this in a simple, affordable and flexible way. Dr. Green uses a
server, free software and a bulk SMS provider to send out the SMS messages.
His system costs very little because he uses freely available open source
software. In addition, his messaging system is flexible. When patients
complained that the initial message ("Take your Rifafour now") was too
drab, he added jokes, pearls of wisdom, and tips about lifestyle management
to light up their day -- but it still reminded them to take their medication.
