Why was FrontlineSMS the right tool for St. Gabriel’s Hospital?
I wrote a bit about the virtues of the software in July, amidst the implementation period. The program has been running for six months, and my latest trip allowed me to document the project’s impact on primary care, treatment coordination, and hospital efficiency. Further, the SMS program has saved thousands of hours of travel time for CHWs and hospital staff, and bolstered the CHWs’ status within their respective communities – which are now connected to the hospital’s resources.
As Ken Banks recently stated, whether or not a mobile tool is suitable is “all about the context of the user.” In succinct terms, here are a few reasons that Ken’s tool was a the right fit for St. Gabriel’s:
It works with simple, readily-available hardware. I used recycled phones and didn’t need to worry about the donated laptop’s specifications.
It doesn’t require an internet connection. The hospital’s web access is shaky, at best.
It is incredibly intuitive and easy to use. The nurse running the program had never used a computer in his life. After one hour of training, he was off and FrontlineSMS-ing.
The hospital found the tool – not the other way around. After I spent time at the hospital two summers ago, the need for connectivity was clear. To meet that need, a tool was employed. It wasn’t forced on me or the hospital.
Straightforward features allowed the hospital to take ownership and get creative, which encouraged user-driven functionality. One example: Auto-replies set to provide CHWs with immediate drug dosage and usage information.
A ten-second demonstration can illustrate the program’s purpose. This hooked clinical staff working within various hospital programs (e.g. HIV treatment coordinator, TB officer, PMTCT director).
Past text messages, and vital patient informaiton, are just two clicks away.
In examining the success of the SMS initiative over the last half-year, the appropriateness of the technology cannot be ignored.
A few, very committed individuals – my mother and sister – set out to answer that question. My mom, Casey Nesbit (DPT), receives every message that is sent to the hospital, via email (thanks to a simple forwarding command in FrontlineSMS). Those messages are in Chichewa. For four months, she translated every message to English.
My sister, Elizabeth Nesbit, decided to code and organize every SMS sent by the CHWs. She’s a sophomore at Rice University, making her way to medical school. She categorized messages by keywords and/or phrases (e.g. symptoms, supplies, patient updates/referrals, deaths, requests for help, requests for visits, meeting coordination).
Under this introduction is a list of all the symptoms found in messages communicated to the hospital. Elizabeth sorted these symptoms out into categories (body pains, digestive and urinary tract, respiratory tract, swelling, skin and sores, malaria and fever, weakness, heart problems, cancer, and other). She broke apart every incoming message this way.
Below the symptom list, you’ll find the fruit of their combined efforts – charts explaining the subject matter of texts to the hospital. Click on any of the charts to view a larger version. These messages fell between mid-August and early December. Shoot me an email if you want to see more of Elizabeth’s analysis.

I sat down with Alex today, to discuss the FrontlineSMS and its impact on the Home-Based Care (HBC) program at St. Gabriel’s. Essentially, he’s a one-man, mobile care unit – focusing on chronically ill patients and those who simply cannot travel to the hospital. The backpack, pictured above, is full of medical supplies.
The SMS network has brought Alex to the homes of 130 patients who would not have otherwise received care. That’s about five responses, per week, to requests for remote medical attention.
Before the SMS program, Alex was visiting around thirty patients a week, rotating through the HBC roster. He now follows up on five patients per week, usually checking in on those who have been recently discharged from the hospital. The CHWs take care of the rest – since the program started, approximately 520 HBC patient updates have reached the hospital via SMS.
The difference in Alex’s HBC activities amounts to about 500 hours and over $1,000 in fuel saved. He has responded to ~40 requests for healthcare supplies (usually dressing materials for wounds and cervical cancer patients). With FrontlineSMS blasting automated responses to drug inquiries and Alex responding to questions regarding basic care, the central SMS hub truly serves the CHWs and their patients.
Alex, who is a highly capable nurse, also holds full shifts in the male ward at the hospital, and is one of two staff members coordinating antiretroviral treatment (ART) for the catchment area. His multitude of responsibilities make time saved in managing the Home-Based Care program extremely valuable.
The first batch of solar panels from G24 Innovations (www.g24i.com) arrived today – I tested one of the products and it quickly charged my phone, to completion, amidst a thunderstorm. More on this later – we are gearing up for training and distribution on Monday.
On Christmas morning, Silia stopped by the guest house to talk about the SMS program. He’s responsible for testing, drug provision, and follow-ups for TB patients. He described how he’s using FrontlineSMS and the network of cellphone-wielding CHWs. Almost all of what follows developed in my absence.
Some sputum-positive patients don’t turn up to receive their medication. It’s Silia’s job to track these patients and get them back on their drug regimens. Before the SMS program, he was visiting an average of 17 patients per week – this took him three trips on his motorbike. Each trip would take ~9 hours. That’s 27 hours per week spent tracking patients in various villages.
The SMS network has allowed Silia to share his workload with the CHWs. He now tracks an average of 20 patients per week via SMS. He simply texts CHWs nearby patients that haven’t turned up. As Silia says, the CHWs provide “immediate feedback.”
The program has been running for roughly 26 weeks. With the shift to SMS-based patient tracking, Silia had an additional 700 hours to utilize. Not surprisingly, he’s been using FrontlineSMS to supplement other areas of his work.
He now visits an average of 4 patients per week, for different reasons. Some messages from the CHWs tell of patients who are too ill to travel to the hospital. Silia will respond by bringing a new supply of drugs. Other messages relay symptoms of community members – e.g. “A man has a chronic cough, and we suspect TB.” Silia will visit the patients, and collect a sputum sample. He’ll return to the hospital to do testing and send the results, by SMS, back to the CHW.
Finally, when patients at the hospital test positive for TB, they’re told which CHWs near their home have cell phones.
Some numbers from the TB program for the last 6 months:
700 hours of follow-up time saved 450 follow-ups via SMS (At least) $2000 in motorbike fuel saved 100 new patients enrolled in TB treatment program
Coming up: Impact on Home-Based Care, PMTCT, Public Health, and HIV/AIDS programs
Here’s the truth – this project involves people, rich in character and experience. It’s not only about the technology. If I’m interested in the tech fulfilling its potential, I’ve got to pay attention to the people.
Case in point:
I spent yesterday mulling over text messages sent through FrontlineSMS over the last four months, noting which CHWs had communicated least. I put together a list of a few CHWs I suspected might be having signal issues. Looking at the map, three of six CHWs on this list were clumped together – clearly, they must not have good reception.
I told Alex about my findings, this morning. He took a look at the names and said, “Well, Bernadeta took her phone with her to Zambia, we’ve discovered that Chrissy is not able to write her own name, and Jereman’s phone battery was stolen while it was charging at the local barber shop.” My time away from the hospital almost made me forget the multitude of stories swirling around these phones and the hospital they’re linked to. With 100 phones in the field, three random problems are to be expected.
Whether or not everyone agrees, I think personal stories convey a project’s successes, as well as their failures. Silia, a hospital attendant who runs the hospital’s TB program, said yesterday, “The SMS project is very, very good – I can get much more work done, instead of driving the motorbike everywhere. It’s very simple – we can expect feedback about patients immediately.” I met the new hospital administrator today, and his second sentence was, “You know, it’s not only beneficial for communication. The volunteers are now committed to their work, and more will follow.”
I’m letting stories from patients, CHWs, and the medical staff at St. Gabriel’s drive my exploration into this project’s value. I turned to people for the direction of the initiative, and I’m turning back to them to measure part of its impact.
Building an SMS Network into a Rural Healthcare System

FAQ #1: Who might benefit from a text-based communications network?
In the summer of 2008, an SMS network was implemented at St. Gabriel’s Hospital in rural Malawi. The hospital serves ¼ million people, spread throughout a catchment area 100 miles in radius. St. Gabriel’s recruited 600 community health workers (CHWs) to serve as volunteer healthcare representatives in their villages. Disconnected from hospital services and resources, the CHWs’ ability to help patients was limited.
Hospitals, clinics, and organizations faced with the defining challenges of rural healthcare – namely, distance and the isolation it breeds – are set to benefit from a low-cost SMS network. Given specific steps and tools to connect individuals, SMS (“short message service”) can provide the missing link – between a hospital and its field worker, patients, support group members, or CHWs in their respective villages.
Ultimately, the aim is for benefits to fall upon those served by the health network. See FAQ #2 for an outline of the benefits derived from a newly implemented SMS program that is providing connectivity for a rural healthcare network.
FAQ #2: What are the benefits for my hospital, clinic or organization and the people it serves?
Implemented at a hospital in rural Malawi in the summer of 2008, a text-based communications network is making a significant impact on hospital operations and patient care. Here is a list of the current functions of the SMS network:
• Requests for remote patient care
CHWs text the hospital staff when immediate care is needed, and the Home-Based Care mobile unit subsequently visits the patient. Patient location and health status are communicated, allowing the mobile team to bring needed drug supplies. According to Dickson Mtanga, a CHW in the pilot program, “When I have a problem with my patient, I just send a message to the hospital, at once. If they are helped and assisted, I feel so much better.”
• Patient tracking
The hospital is now able to track patients in their distant communities. According to Mr. Ngalande, “Each and every department is free to use FrontlineSMS. We have ART, Home-Based Care, TB, PMTCT (Prevention of Mother to Child Transmission). For example, TB patients who are not coming for their appointments, we use FrontlineSMS to text volunteers close to the patient’s village. It’s easy to get feedback from the community.”
• Checking drug dosages
CHWs in the field have been given basic drug supplies (e.g. Panadol, Ferrous Sulfate, eye ointments) for primary care. The CHWs now check drug dosages and uses within seconds. When FrontlineSMS receives an SMS with a drug name, it automatically responds to the health worker with that drug’s information.
• Patient updates
CHWs regularly update the hospital staff with regards to patient status, including reporting patient deaths. These messages have created a post-discharge connection to patients’ well being.
• Coordinating Home-Based Care visits
In addition to responding to medical emergencies in the communities, the Home-Based Care (HBC) unit also follows a schedule of home visits – sometimes checking on patients have been discharged recently. Other patients are enrolled in the hospital’s palliative care program. Before traveling to the patients’ villages, the mobile unit text messages CHWs in close proximity to the clients they plan to visit. Any response by the CHW (e.g. “Patient is not at home.”) is forwarded to the mobile team’s phone, allowing medical staff to maximize their productivity by visiting available patients.
• CHW-to-CHW communication and group mobilization
CHWs are now communicating and collaborating. All texts are shuttled through the hospital, and FrontlineSMS commonly relays messages and requests between CHWs. This has been an important function in setting meeting dates for Village AIDS Committees and linking HIV/AIDS support groups. Hospital activities throughout the catchment area (including microfinance and Positive Living programming) are organized using the SMS network. Baxter Lupiya, a CHW in TA Kalolo, notes, “We used to travel a long distance. Now, we have easy communication with others. The program must be continued, because it is so good!”
• Integrating connectivity into HIV counseling
HIV Counseling and Testing (HCT) at the hospital has been augmented because of the SMS network. If a client tests positive, he or she is paired with to an HIV-positive CHW with a phone – these volunteers act as models for Positive Living and provide comfortable, relatable links to the hospital.
• CHW status
The connection to hospital services has solidified the CHWs’ role as legitimate healthcare representatives in their villages. The patients and their communities, according to the program’s participants, have noticed the phones, each one clearly marked with the hospital’s logo.
• Incentives and accountability
The phones provided very concrete incentives for the volunteer work done by the CHWs. The SMS network created, for the first time, a way to track the CHWs’ activities, paving the way for more informed decisions regarding allocation of resources (e.g. which CHWs should receive bicycle ambulances).
The listed benefits developed organically from a particular hospital’s needs. Undoubtedly, future demands will uncover new functionalities. For example, the hospital in Malawi is exploring the use of FrontlineSMS’s ‘Forms’ function to collect structured data regarding the status of palliative care patients – information that can quickly be exported to donors and organizations supporting those patients.
FAQ #3: What technology do I need?
Here is a quick list of the equipment used in Malawi:
- 75 Motorola V195 cell phones, purchased at $15/phone from a recycling company
- 15 Nokia 6210 cell phones, $40/phone
- 10 Nokia 6100 cell phones, $50/phone
- 1 Falcom SAMBA75 GSM modem, $200
- 1 donated Compaq Presario laptop
- 100 cell phone chargers + Malawian adapters
- FrontlineSMS version 1.4.7, free software downloaded at www.frontlinesms.com/download
- FrontlineSMS is running on a Windows Vista operating system
A few notes on hardware and software:
• As long as the cell phones get service and function on your local network – they can send/receive text messages – they will work with FrontlineSMS. Motorola V195 phones were chosen for the program in Malawi because of their low cost and ease of use. The Nokia phones were chosen for similar reasons – teaching texting using the Nokia models (6100 and 6210) was straightforward. The steps for sending an SMS with the Motorola V195 were slightly more complex.
• Each distributed phone was labeled with the hospital logo. This was important for ownership and accountability, along with community transparency and health worker status.
• I had the Malawian Department of Surveys print a map of the hospital’s catchment area. On this map, color-coded pins were placed, showing where distributed phones are located (along with each CHW’s program type, e.g. Home-Based Care or ART Monitoring).
• When selecting phones for your network (if you are purchasing new or used phones), keep a few things in mind:
1. Consider the experience of the user. In most situations, simpler is better – sending and receiving an SMS is meant to be easy.
2. Check to see which bands (e.g. GSM 900 band) work with your local network, and make sure the phone supports that band. Here is a site with GSM coverage maps for a number of countries: http://www.gsmworld.com/roaming/gsminfo/index.shtml
• The new versions of FrontlineSMS are configured to run on a number of operating systems. You can find comprehensive information on Windows, Mac and Linux compatibilities here: http://www.frontlinesms.com/download/requirements.php
• Although the SAMBA75 GSM modem is being used in Malawi, a number of modems and cell phones may be connected to the computer running FrontlineSMS. For a list of phones and modems that work well, see the following link: http://www.frontlinesms.com/download/requirements.php
FAQ #4: Do I need an internet connection?
All that is necessary is a cellular network signal on your modem or phone – no internet connection is needed. If you can send and receive text messages in your area, FrontlineSMS will work. Check the GSM coverage map link for more information on your local network: http://www.gsmworld.com/roaming/gsminfo/index.shtml
FAQ #5: How expensive is an SMS network?
The cost of your network will largely depend on the scale (e.g. the number of phones and the volume of text messages processed per day). Here are the numbers in Malawi:
• The pilot network includes 75 community health workers (CHWs) and 10 members of the hospital staff.
• During the final weeks of the implementation period (weeks 7 and 8), an average of 10 messages were received from the hospital per day. The number of responses by the hospital (along with new patient tracking requests) varied.
• Once the phones are distributed, the only running cost is the rate per SMS. Given that one SMS costs 10 cents, and they are free to receive, the program is running on just over $1/day. So, $4,000 will fund the SMS network for a little over 10 years.
FAQ #6: How do I distribute communication credit?
There are a few options here. Your distribution method will depend on the structure of your healthcare delivery teams and/or volunteer organization. This is how we tackled this logistical issue in Malawi:
• Celtel, the local network provider, has a ‘Me2U’ service that allows a user to send communication credit (“units”) from one phone to another via text message.
• Every phone that we distributed had a 2-digit identification number engraved on its case, specific to that phone and SIM card.
• Using the keyword and auto-forward functions in FrontlineSMS, we automated the entire top-up process, allowing the CHWs to request automatic unit refills.
• For example, the owner of phone #11 sends a message to the hospital, “11 units” which is recognized by FrontlineSMS. FrontlineSMS then sends a message to Celtel’s Me2U service, requesting that phone #11 receive another dollar of credit.
Other options include passing large quantities of units to trusted individuals, such as CHW leaders, coordinators, or other staff who have regular contact with those receiving phones. The key to maintaining accountability is making it clear that FrontlineSMS documents every message received by the hospital. Be sure it is understood that the communication credit given to your contacts should be used to communicate with your hospital, clinic, or organization.
FAQ #7: How much staff training is required?
No technical experience is required for implementing or sustaining an SMS network. The nurse in Malawi managing day-to-day communication, using FrontlineSMS on the hospital laptop, had never used a computer before the SMS program was introduced.
Within the first week, the hospital staff understood the functionalities of FrontlineSMS – for this reason, the uses of the SMS network developed organically, shaped by the needs of the hospital, the CHWs, and the patients they serve.
After a 1-hour training session on operating FrontlineSMS, the nurse and ART coordinator were left with a simple, step-by-step operation guide. The guide, available to anyone who requests it, uses images of FrontlineSMS, showing how to:
1. Send a message
2. Check for new messages
3. Add/delete a contact or group
4. Copy and paste text (a useful explanation, for first-time computer users)
5. Ensure that FrontlineSMS is communicating with the attached modem (or phone)
6. View a specific contact’s message history
FrontlineSMS also has a built-in Help guide, which explains in detail each function, including forms, e-mail, and keywords. The keywords and their respective automated action (e.g. auto-forward, auto-reply) were all created on the ground, and I have absolutely no technical background.
The program, along with the SMS data collected, is purposefully uncomplicated. According to Alex Ngalande, the nurse running FrontlineSMS for the pilot program, “[Setting up FrontlineSMS] was very quick. And, people didn’t know that this thing could work here – because, it’s our first time to have this kind of system whereby people can directly communicate with the hospital… It’s simple and straightforward.”
FAQ #8: How much time does it take, per day, to manage the SMS network?
Towards the end of the pilot period (weeks 7 and in Malawi, two members of the hospital staff were spending 15 minutes every morning and 15 minutes at the end of the workday managing incoming and outgoing SMS data.
This management time (an average of 30 minutes per day) included reading new messages, responding to urgent requests, forwarding CHW-to-CHW messages, passing on patient updates to relevant hospital staff, sending out patient tracking requests, and processing other outgoing texts.
FAQ #9: How do I conduct SMS training?
The success of the SMS program relies on the users being able to operate their phones. For this reason, patient training and a slow rollout are recommended. In Malawi, we trained 10-15 community health workers (CHWs) per week for 6 weeks (75 CHWs in all) – each session lasted about three hours. A few tips, especially applicable if your contacts are first time cell phone users:
1. Start with the basics. The first step displayed on our training posters? Open the phone.
2. Keep the training groups small.
3. Take simple steps to make your instructions outstandingly clear – we made posters showing which buttons to press.
4. After each ‘lesson,’ have a member of the group lead the others through what they learned (e.g. after teaching the group how to check for new text messages in the phone’s inbox, have a participant repeat the steps).
5. Poll the group to find out how many have used a cell phone before. Have the experienced participants guide others through the SMS steps.
6. Have the group practice texting something simple (e.g. “Malawi”), then something more difficult (e.g. their full name and birth date).
7. Have expectations for the group prepared (e.g. what will be communicated, and when they are expected to communicate).
8. The most committed volunteers received the first phones. This distribution method contributed to the success of the pilot program.
The training in Malawi was conducted in Chichewa by hospital staff. The staff running the training sessions knew the CHWs, and were used to speaking to groups.
FAQ #10: What is the best power source for the cell phones?
Depending on your area of operation, electricity may or may not be widely available or affordable. The pilot in Malawi looked at a few options:
• When asked, “Who has access to electricity?” every CHW said they could charge the phones on their own. This turned out to be a half-truth – they had to pay a small fee to charge the phones at a local barbershop, as an example of a local solution.
• We created a local charging station, next to the hospital, where the CHWs could charge their phones free of charge.
• I brought hand-powered chargers, which simply did not work.
• As a short-term solution, CHWs in the most remote locations were given battery-powered phone chargers (which provide 2-3 full charges per AA battery).
• For sustainable, remote, off-the-grid charging, individualized solar panels may be the best option. Solar panels will power the SMS network for the pilot program in Malawi.
FAQ #11: Do the CHWs communicate with each other?
Absolutely. This was one of the first questions raised by the CHWs in the pilot group in Malawi. CHW-to-CHW communication is vital for group mobilization, and has a large impact on day-to-day CHW activities. It’s important to realize, however, that FrontlineSMS will not track messages between phones in the field. If one CHW wants to contact his colleague many miles away, they are asked to send a message to the hospital – along with directions to forward the message: e.g. “Send to John: The support group will meet this Saturday, at 10 o’clock in the morning. From Dickson.” This system ensures that all messages are accounted for.
FAQ #12: Where can I find more information on FrontlineSMS?
Visit www.frontlinesms.com for more information on the free, open-source program. The site includes a detailed description of the software, demo, map of current users, and download request form.
The following is an interview with Alex Ngalande, the Home-Based Care nurse in Malawi who is currently running FrontlineSMS on setting up and using the program:
Here is an interview with a community health workers involved in the pilot program. She speaks on volunteer activities, as well as the impact the SMS-based network has on patient care:
Over the last week, there’s been a cascade of communication. A few examples, of many:
- A man missed his appointment with a TB officer. A CHW was texted, who reported the man had gone to Zambia for a funeral. The hospital will be notified upon his return.
- An HIV support group met, and decided on new member guidelines. Via SMS, the group leader asked the hospital to print copies for the lot.
- A CHW asked about ferrous sulfate dosages, so he could administer the proper amount to an anemic child.
I’m at the halfway point of my trip, and after five weeks on the ground, a discussion of the tools is in order. Ken Banks, the creator of FrontlineSMS, recently wrote an article about the emerging social power of mobiles for BBC News:
Ken is building a community of implementers. Interested parties should visit two of the group’s sites: www.kiwanja.net and www.frontlinesms.com.
It is precisely due to FrontlineSMS’s smart simplicity that the project has developed organically – first and foremost, to meet the hospital’s needs as it serves its catchment area. The quick uptake of the project was fueled, in no small part, by how user-friendly FrontlineSMS is, as a central communications hub.
It also has provided solutions to some potentially tricky questions. A quick example:
Text messages cost 10 cents. Units can be sent from one phone to another via Celtel’s Me2U service, but managing the units of 100+ phones manually is near impossible. So, I had to find a way to both monitor each phone’s unit level and top up (replenish depleted reserves) automatically.
Before leaving Stanford, I engraved each phone’s faceplate with a two-digit ID number. Using FrontlineSMS’s auto-forward function, I’ve set up a system to automatically top CHWs up. When they are running low on units, CHWs can text “(ID number) Units” to FrontlineSMS. Subsequently, a message is sent to Celtel, with instructions to top up that particular CHW. System abuse is unlikely and avoidable – the volunteers know that FrontlineSMS records every message received, sandwiched by unit requests.
We’re starting to explore additional functionalities of FrontlineSMS. Each CHW is given a kit of basic medications – a portion of the questions we’re fielding involve those drugs. We’ll set up an auto-reply system so that any message containing a given drug name returns a summary – function, dosages, etc. – for that drug.
Above – another happy group of health workers, the program’s newest inductees. By the end of next week, there will be 50 phones in the field – next Wednesday, we’re adding Reproductive Health and Youth Counseling volunteers to the network.
Below, you’ll see some of the CHWs re-teaching SMS steps to the rest of the group – a key component of the training sessions.
Once the session ended, a few of the CHWs reviewed their notes:
Walking through a village this afternoon, I happened upon three separate barber shops, each advertising Phone Charging services.
Malawians understand mobiles. It’s time to put the technology to work.
Next week, amid further CHW orientation, we’re holding comprehensive training sessions for hospital staff – so that TB officers, ART directors, pediatric nurses, PMTCT coordinators, clinicians, and VCT volunteers alike can use FrontlineSMS to contact the CHWs.
Today, Alex and I headed into the field. The goal was to find seven patients – the hospital had been alerted of their declining health, by SMS, through seven different CHWs. The motorbike-enabled, text-message-guided journey through the catchment area completed a (once) theoretical cycle: The CHWs surveying communities, then communicating their most urgent needs; the hospital gathering resources (diesel, drugs, and medical advice), then traveling to the villages.
Often, we stopped by the CHW’s home. Above, Pascalia directs Alex to the patient’s location. After the picture, she ran home, put on her St. Gabriel’s Hospital ‘Positive Living’ shirt, and joined us for the consult.
A brief overview of some of the cases:
- An HIV-positive man, on ARVs, with Karposi’s Sarcoma and wet beriberi.
- A 13-year-old girl with stomach cancer and massive ascites. Pascalia is the closest CHW, but her bicycle ‘ambulance’ is not operable. So, we texted Moreen, who is just a few villages away. She’ll bring her ambulance, and get the girl to the hospital.
- A 72-year-old man, who is sputum-positive for TB, and was complaining of severe joint pains.
- An man, suffering from epilepsy, fell into a fire two weeks ago. He has developed a massive ulcer on his left heel. Left, Alex is explaining how to wrap gauze. The man happily let us take a picture of the scene.
We met with the hospital staff when we returned – after traveling 100 km in 6 hours, and visiting 7 different villages. Everyone agreed that the day was a success.
The entire hospital staff is now fully aware of the project and its goals. We’re all moving in the same direction. The consensus is that a second, simple cycle, once disseminated, will greatly aid follow-up and monitoring programs: The medical staff (looking to follow up on a TB patient, for example) consulting the CHW map, and contacting the nearest CHW; the CHW checking on the patient, and responding to the hospital re: their status.
This week, another group of jubilant CHWs was trained in texting. Below, you can watch a one-minute excerpt of the training session – Alex is explaining the first steps in operating the phone. At the end, you’ll hear a chorus of ‘success sounds’ – all the phones turning on for the first time by their owners’ manipulations.
The week has gone very well, and the project’s initial success has been noticed by each arm of the hospital. I took a minibus into Lilongwe, which turned out to be a fruitful venture – I rode into Namitete on a bike taxi wielding extra maps, an assortment of push-pins, and a few surge protectors (which will establish a permanent location for CHWs to charge their phones at the hospital).
Each CHW we train and distribute a phone to will be placed on a map of the hospital’s catchment area, with a different color pin, depending on their program (Home Based Care, ART Monitors, Reproductive Health Volunteers, Counseling, or Youth Volunteers). Particularly committed volunteers assume multiple roles in their community – they’re distinguished by blue pins. The idea is to have the maps, with hundreds of CHWs’ locations marked, displayed clearly for the clinical staff at the hospital. This way, a clinician looking to track down a patient need only consult the map, find the nearest, appropriate CHW’s identifying number (written on the pin), and send out a text. Here are the new maps, along with the locations of the first 20 dispersed phones:
Tomorrow afternoon, I’m attending the staff meeting for those involved with the hospital’s antiretroviral therapy (ART) program. I’ll be explaining the project, and the group will determine a protocol for communicating with adherence monitors in the field. Below, you’ll see me, sitting with Grace, who coordinates the hospital’s ARV provision.
As always, thanks for reading. Any ideas, as this expands?
