Abstract: 

This paper presents Open Data Kit (ODK), an extensible, open-source suite of tools designed to build information services for developing regions. ODK currently provides four tools to this end: Collect, Aggregate, Voice, and Build. Collect is a mobile platform that renders application logic and supports the manipulation of data. Aggregate provides a “click-to-deploy” server that supports data storage and transfer in the “cloud” or on local servers. Voice renders application logic using phone prompts that users respond to with keypad presses. Finally, Build is a application designer that generates the logic used by the tools. Designed to be used together or independently, ODK core tools build on existing open standards and are supported by an open-source community that has contributed additional tools. We describe four deployments that demonstrate how the decisions made in the system architecture of ODK enable services that can both push and pull information in developing regions.

Abstract: 

Although para-social workers carry the primary responsibility in providing essential services to the growing population of orphans and vulnerable children in Tanzania, they are often not paid for this work. Moreover, these para-social workers are unable to access governmental resources due to the lack of an efficient means of reporting their needs to relevant government officials in a timely manner.

In this paper we describe a text message (SMS) based solution that harnesses the prevalence of mobile phones coupled with several Open Source tools to empower these para-social workers. Specifically, we build a more efficient mechanism for reporting summary data on orphans and vulnerable children to relevant government officials in a cost-effective and efficient manner. This paper reports on our needs assessment process, reviews the related work, describes the implementation and testing of our prototype solution, and concludes with a discussion of relevant future work.

PoiMapper: Mobile Data Collection Through Points-of-Interest in Kenya data sheet 3493 Views

PoiMapper, a product from Pajat, is a mobile application for data collection, hosting, and sharing. It works on a feature phone with Java capability and allows a user to design a case-specific questionnaire to collect field data, including numbers, text, and photo images. Through this, it supports the collection of point-of-interest (POI) data -- hence the name, PoiMapper -- and is currently being tested in this capacity in Kenya in collaboration with Plan Kenya, Plan Finland, Helsinki University of Technology, and University of Nairobi. The pilot is ongoing and an evaluation is to be done a month from now.

Basic Information
Organization involved in the project?: 
Project goals: 

Plan International is in the middle of a 4-month pilot in Kilifi, Kenya to use PoiMapper to create more detailed maps to support program interventions.

Brief description of the project: 

PoiMapper, a product from Pajat, is a mobile application for data collection, hosting, and sharing. It works on a feature phone with Java capability and allows a user to design a case-specific questionnaire to collect field data, including numbers, text, and photo images. PoiMapper is being tested as part of a 4-month pilot initiative in Kilifi, Kenya, with Plan International. The goals of the initiative are to contribute to the development of GIS software for both mobiles and computers and to ensure that technology is used to improve maps in terms of their accessibility and ability to provide more up-to-date and dynamic information.

Target audience: 

Field workers with Plan International in Kilifi, Kenya are currently using the PoiMapper system to map points of interest.

What worked well? : 

The ability to customize the application has been a strength for Njuguna in Kenya, as it give complete flexibility to cater the application to the needs of Plan International. Other stregths include the ability to use affordable, low-end mobiles, avoiding the use of expensive GPS devices. The application runs on a phone whose functionality is familiar, including the use of the basic mobile phone camera.

What did not work? What were the challenges?: 

A technical challenge arose when phones ran out of memory. This, in part, led to a redesign in which the service was changed from a survey approach to a database approach, where the majority of data is transferred and stored in the database.

Another challenge emerged when users wanted to change the questionnaires over time. The system had to be designed to be easy to add and change questions, Lounamaa said.

Report/White paper
Abstract: 

In the context of the rapid growth of mobile phone penetration in developing countries, mobile telephony is currently considered to be particularly important for development. Yet, until recently, very little systematic evidence was available that shed light on the developmental impacts of mobile telecommunication. The Information and Communication Technology for Development (ICT4D) program of the International Development Research Centre (IDRC), Canada, has played a critical role in filling some of the research gaps through its partnerships with several key actors in this area.

The objective of this paper is to evaluate the case of mobile phones as a tool in solving development problems drawing from the evidence of IDRC supported projects. IDRC has supported around 20 projects that cut across several themes such as livelihoods, poverty reduction, health, education, the environment and disasters. The projects will be analyzed by theme in order to provide a thematic overview as well as a comparative analysis of the development role of mobile phones. In exploring the evidence from completed projects as well as the foci of new projects, the paper summarizes and critically assesses the key findings and suggests possible avenues for future research.


Mobile Mapping for Rapid Field Assessment of Health Infrastructure in Indonesia

Posted by cycadme on Oct 01, 2010

The rural population of eastern Indonesia generally has limited access to health services due to rugged topography, poor roads and limited health resources. Moreover, there are no comprehensive audits of health infrastructure at the district level resulting in poor coordination of health resource allocation. This project is using mobile field data collection techniques to identify gaps in health services to enable more effective and equitable delivery of scarce health resources to remote and poor regions. 

The study tested the assumption that recent changes in mobile mapping and GIS technologies have made them appropriate and effective tools for public health applications in rural, developing contexts.  Three primary factors seen to be facilitating more widespread use were: (1) decreasing hardware costs, (2) the technological convergence of GPS/mobile-phone/PDA (personal digital assistant) hardware and (3) the development of free/open-source spatial data software.

New mHealth Case Study: Sana Mobile

Posted by MohiniBhavsar on Sep 17, 2010

Recently, MobileActive.org spoke to the Sana Mobile team to understand how the Android-based m-health application is being used in India. The Sana application, developed at MIT's Next Lab by students and volunteers, seeks to facilitate remote consultation between specialists, often in urban centers, and community health workers working in remote low-resource settings.

Instant remote consultation for complicated cases requiring specialist input helps bring care to patients, who would otherwise have limited access to tertiary care. Sana is developed on the Android platform, enabling users to integrate voice recordings, video and high resolution images in the diagnostic process.

Sana Mobile: Connecting Big-City Care to Patients in Remote Villages data sheet 6110 Views

Decision making support for nurses and health workers, even when connectivity is poor or low, is possible with Sana Mobile, an Android-based mobile health application. Formerly known as Moca Mobile, the Sana technology facilitates remote consultations between health care specialists and community health workers in remote areas.

Sana Mobile started at MIT's NextLab, where developers, faculty and students collaborate to tackle a problem using mobile technology. The Sana technology was developed by Sidhant Jena, Sana team lead and Harvard Business School student and Russell Ryan, lead engineer and MIT student.

When general practitioners lack the expertise to diagnose a case, they refer patients to specialists, who may not be easily accessible. The Sana technology addresses the lack of accessibility to specialty care in places, where specialist doctors and tertiary care centers are sparse.

How does Sana Mobile work?

Basic Information
Organization involved in the project?: 
Project goals: 

One of the largest problems facing the developing world is a lack of trained physicians. While there is not a shortage of untrained or semi-trained workforce, many health workers in many developing nations are not able to dispense adequate care due to a lack of expertise.

The Sana technology seeks to address the lack of accessibility to specialty care in places, where specialist doctors and tertiary care centers are sparse.

Brief description of the project: 

Oral cancer is one of the most common cancers in India. It is related to the cultural practice of chewing paan masala and gutka, forms of chewing tobacco. It is estimated that about 40% of men and 15% of women chew tobacco on a regular basis. Detecting risk of oral cancer earlier is important for affordable treatment as late stage tumors can be very expensive to treat. To survey the risk of oral cancer in their community, Mazumdar Shaw Cancer Center and the Narayana Hrudayalaya Health to ran a pilot test in and around Bangalore over six months. One pilot was run in Belgaum, Raichur, a rural town about 12 hours away from the city of Bangalore. The other pilot was run in Bangalore. Equipped with the Sana application, ASHAs (community health workers) went door to door in and around Bangalore, asking questions and taking pictures of oral lesions, which were evaluated by oral surgeons. In six months, they were able to screen about 400 high-risk cancer patients and detected numerous lesions using Sana. Twenty ASHAs were trained in using the Sana software in Belgaum.

Target audience: 

For this pilot, risk of oral cancer was assessed for men and women chewing tobacco. But the Sana application is also being used to do a large scale risk assessment for cardiovascular disease, to screen maternal complications (e.g. preclampsia) and assess nutritional status of children.

Detailed Information
Length of Project (in months) : 
6
Status: 
Ongoing
What worked well? : 
  • Sana invested in building local developer capacity in India. Local developers cost less than having an international technology consultant to conduct training.
  • Lots of enthusiasm from leaders at the Narayana Hrudayalaya hospital
  • Funding for Sana developers at MIT to travel to India to test and train users came from external support, not from program budget of the clients.
What did not work? What were the challenges?: 
  • Semi- to low-literacy amongst community health workers can be a challenge if an application is available in limited languages. CHWs in Belgaum did not speak Kannada (the local script) or English. Developers adapted Sana to replace text in the medical procedures with voice prompts and pictorial labels
  • Health workers/nurses were not familiar with the touchscreen and needed some additional training and practice in order to understand how to use it (i.e. using fingerpad or fingernail to enter data)
  • Cost of phone was a major limiting factor
  • Some resistance faced from physicians, who were not quick to adopt a technology-based work flow management tool
  • The Sana Team is a volunteer based organization, and it is difficult for the team of developers to contribute time resources, but they consistently offer feedback to Sana users on their google group.

Sana Mobile

Posted by MohiniBhavsar on Sep 16, 2010

Sana, is a student organization based at the Massachusetts Institute of Technology (NextLab, Center for Transpotation and Logistics, Engineering Systems Division) that offers an end-to-end system that seamlessly connects health workers to medical professionals. In addition, the group assists its partner organization with implementation through collaborative innovation. The team consists of volunteers with diverse background – medicine, computer science, clinical informatics, health policy, social sciences, and business and operations management. It strongly believes that there is a need to bring together experts from various disciplines in order to design an operating system around the delivery of care that is facilitated by mobile technology. The technology is crucial, but not the sole component of the solution. It is the centerpiece of a learning system that is designed not only to improve clinical outcomes, but the health delivery process itself.

Abstract: 

It is believed that once groups acquire information and communication technologies (ICTs), they will prosper. When the most marginalized members of society have better access to information and knowledge, the likelihood of improving their livelihoods also increases. Past literature has dealt with the difficulties that such groups have had in accessing and acquiring technology because of institutional obstacles. This thesis examines the institutional obstacles and constraints faced by groups once they have
acquired ICTs.

I intend to examine why, despite the rapid diffusion of ICTs in developing countries over the past decade, there has not been a dramatic improvement in the alleviation of poverty. In particular, this thesis will explore the use of mobile phones in the context of development and poverty reduction in Sub-Saharan Africa and the relationship between institutions and local stakeholders to strengthen livelihoods.

This thesis hypothesizes that development initiatives using a collaborative, hybrid approach that integrates effective institutional involvement with inclusive grassroots participation will be more sustainable and scalable than those that attempt solely topdown or bottom-up approaches. In other words, initiatives devised by institutions that rely upon structures incorporating local communities into projects will be found to be more successful in both the short-term and long-run. Case studies have been selected to illustrate how this hybrid approach is ultimately more successful in improving the livelihoods of the rural poor than approaches that are either primarily driven by the topdown or bottom-up.

The four cases considered in this thesis will describe the extent to which projects or initiatives using mobile phones have been successful in meeting the needs of local beneficiaries and improving their livelihoods.

Abstract: 

This paper presents a case study of the efficiency gains resulting from the introduction of electronic technologies to monitor and support adherence to highly active antiretroviral therapy (HAART) in Guguletu, South Africa. It suggests that the rollout of HAART to such resource-poor communities can be assisted significantly by the introduction of modified cellphones (to provide home based support to people on HAART and improve the management of adherence data) and simple barcoding and scanning equipment (to manage drug supplies). The cellphones have improved the management of information, and simplified the working lives of therapeutic counsellors, thereby enabling them to spend less time on administration and to devote a constant amount of time per
patient even though their case loads have risen threefold. It has helped integrate the local-level
primary health service provision of HAART with the kind of centralised data capture and analysis
that could potentially support a national HAART rollout.


No to Fake Drugs: Battling Pharma Counterfeiting With SMS And Mobile Tech

Posted by PenelopeChester on Aug 24, 2010

Femi Soremekun, managing director of Nigeria-based Biofem Pharmaceuticals, is all too familiar with the fight against counterfeit drugs. In late 2008, a distributor notified him that he suspected that one of Biofem’s products, Glucophage, was being counterfeited. After checking batch and inventory numbers, Soremekun reassured him there was no evidence of such activity. It was only after more allegations surfaced that he sent a sample to French manufacturer Merck & Co. to be analyzed. Turns out the claims were correct. “I was very shocked,” Soremekun says. “[The counterfeiters] got into my market, counterfeited my product, and I wasn’t even aware of it. I was losing sales.”

It was around this time that Soremekun learned about Sproxil, a start-up company that is part of a consortium that includes Nigeria’s pharmaceutical industry association and the country’s regulating agency. The group explores technology-based strategies to tackle drug counterfeiting. On the sidelines of the consortium, Biofem and Sproxil discussed implementing a drug-certification process in order to restore Biofem customers’ confidence in Glucophage. Following a successful five-month trial in Nigeria involving about one million units of Biofem’s product, the company has seen sales pick up again. “We ended up being called the guinea pig,” Soremekun jokes.

Abstract: 

Handheld computers have untapped potential to improve HIV/AIDS programs in sub-Saharan Africa, particularly in the collection of survey data. We conducted an experiment in three neighborhoods of Luanda, Angola to assess the impact of the technology on people’s comfort and willingness to disclose sensitive personal information, such as sexual behavior.

Participants were asked about their HIV/AIDSrelated knowledge, attitudes, and practices by local interviewers using either handheld computers or paper surveys. T-tests showed no differences between participants’ self-reported comfort across handheld and paper conditions. However, participants in the handheld condition were more likely to give socially desirable responses to the sexual behavior questions than participants in the paper condition. These results suggest that using handheld computers in data collection in sub-Saharan Africa may lead to biased reports of HIV/AIDS-related risk behaviors.

Abstract: 

Background: Survey data are traditionally collected using pen-and-paper, with double data entry, comparison of entries and reconciliation of discrepancies before data cleaning can commence. We used Personal Digital Assistants (PDAs) for data entry at the point of collection, to save time and enhance the quality of data in a survey of over 21,000 scattered rural households in southern Tanzania.

Methods: Pendragon Forms 4.0 software was used to develop a modular questionnaire designed to record information on household residents, birth histories, child health and health-seeking behaviour. The questionnaire was loaded onto Palm m130 PDAs with 8 Mb RAM. One hundred and twenty interviewers, the vast majority with no more than four years of secondary education and very few with any prior computer experience, were trained to interview using the PDAs. Logical checks were performed and skip patterns taken care of at the time of data entry. Data records could not be edited after leaving each household, to ensure the integrity of the data from each interview. A small group of interviewees from the community, as well as supervisors and interviewers, were asked about their attitudes to the use of PDAs.

Results: Following two weeks of training and piloting, data were collected from 21,600 households (83,346 individuals) over a seven-week period in July-August 2004. No PDA-related problems or data loss were encountered. Fieldwork ended on 26 August 2004, the full dataset was available on a CD within 24 hours and the results of initial analyses were presented to district authorities on 28 August. Data completeness was over 99%. The PDAs were well accepted by both interviewees and interviewers.

Conclusion: The use of PDAs eliminated the usual time-consuming and error-prone process of data entry and validation. PDAs are a promising tool for field research in Africa.

Abstract: 

Epi Data and Epi Info are often used together by public health agencies around the world, particularly in developing countries, to meet their needs of low-cost public health data management; however, the current open source data management technology lacks a mobile component to meet the needs of mobile public health data collectors. The goal of this project is to explore the opportunity of filling this gap through developing and trial of a personal digital assistant (PDA) based data collection/entry system. It evaluated whether such a system could increase efficiency and reduce data transcription errors for public surveillance data collection in developing countries represented by Fiji.

120 participants were recruited from the Fiji School of Medicine were randomly assigned to be interviewed by one of six interviewers in one of the two ways: (1) paper-based survey followed by PDA survey and (2) PDA survey followed by paper-based survey. Data quality was measured by error rates (logical range errors/inconsistencies, skip errors, missing values, date or time field errors and incorrect data type). Work flow and cost were evaluated in three stages of the survey process: (1) preparation of data collection instrument, (2) data collection and (3) data entry, validation and cleaning. User acceptance was also evaluated in the two groups of participants: (1) data collectors and (2) survey participants.

None of the errors presented in 20.8% of the paper questionnaires was found in the data set collected using PDA. Sixty-two percent of the participants perceived that the PDA-based questionnaire took less time to complete. Data entry, validation and cleaning for the PDA-based data collection from 120 participants took a total of 1.5 h, a 93.26% reduction of time from 20.5h required using paper and pen. The cost is also significantly reduced with PDA-based protocol. Both data collectors and participants prefer to use PDA instead of paper for data collection. The trial results prove that eSTEPS is a feasible solution for public health surveillance data collection in the field. Several deficiencies of the softwarewere also identified and would be addressed in the next version.

eSTEPS offers the potential to meet the need for an effective mobile public health data collection tool for use in the field. The eSTEPS field trial proves that PDA was more efficient than paper for public health survey data collection. It also significantly reduced errors in data entry. The later benefit was derived from the software providing its users with the flexibility of building their own constraints to control the data type, range and logic of data entry.

During a study conducted in January 2010 by researchers of the Columbia University Mechanical Engineering Department in New York City, approximately 300 farmers were surveyed in rural Mali. Farmers were randomly sampled via standard proportional, stratified, cluster techniques. Data collection took place through the use of HTC G1 smartphones running Google’s Android operating system. The phones were equipped with Open Data Kit (ODK) software; a system that immediately digitizes data for analysis, allows for remote monitoring of the collection progress, and facilitates the gathering of data, eliminating the need for paper surveys and therefore significantly reducing survey times. ODK has the potential for a profound impact on the future of data gathering, particularly in development applications where locations may be remote and budgets tight, yet where mobile phone use is rapidly increasing with the expansion of service
coverage.
