LSHTM Open Data Kit

LSHTM Open Data Kit : A server hub and device library for academic researchers

The London School of Hygiene & Tropical Medicine is a world-leading centre for research and postgraduate education in public and global health with active research in more than 100 countries. Our mission to improve health leads our staff and students to work in some extremely challenging circumstances; from sites of outbreaks, through lawless jungles to refugee camps and lonely islands in big oceans. Our diverse portfolio of research projects, clinical trials and public health interventions have complex data needs that paper forms simply can’t meet in the age of open research.

Doing a PhD that involves several months island-hopping in the Western Pacific sounds too good to be true. For two of our students it really was and the reality of their epidemiological field surveys in the Solomon Islands, Fiji, Vanuatu and Kiribati was weeks at sea, bouts of dengue fever, rain, weight-loss, more rain, an 8.0 magnitude earthquake and a big pile of sloppy paper that used to be case recruitment forms. These studies aimed to inform regional disease control protocols and 10,000 sheets of paper in the bottom of a canoe in the middle of the Pacific Ocean just wasn’t working out as planned.

Our solution was to use waterproofed Android phones running ODK and the result was real time data flows from some of the most remote places on earth to our secure institutional servers in London, UK. That first data set that we collected with ODK felt like a minor triumph, but it wasn’t one that we could lay any claim to. The ODK development community had already invested years of time and effort to get it to the point where using ODK Collect was so easy.

At this stage we wondered how we could use what we’d learned in the Pacific Islands to encourage a culture of electronic data collection at LSHTM. Making new instances of the server was now a simple process and sharing the system with our colleagues felt like an obligation to the LSHTM mission. The result was the LSHTM Open Data Kit project (odk.lshtm.ac.uk) and we now provide ODK servers and technical support to any LSHTM staff member, student or collaborator under a pay-what-you-can (PWYC) agreement. To further reduce the need for up-front payments by the end-user, we have reinvested the PWYC fund in a ‘device library’ that includes a large number of armoured Android devices, powerbanks, solar briefcases, environmental sensors and other equipment. As with the servers, access to the device library costs the end-user only what they are able and/or willing to pay.

In the coming year we aim to expand our service to our neighbours at the Bloomsbury Colleges (Birkbeck, The Royal Veterinary College, The School of Oriental and African Studies) and University College London before maybe taking the service further afield. Expansion and long-term sustainability will require substantive funding, but we hope to source the majority of capital from some of the 50+ global health charities, NGOs and government departments whose work we have supported over the past two years. This will continue to defer costs away from the end-users.

To date the ODK group has supported more than 75 separate projects. We have established developed teaching materials and run regular training sessions. Our device library is fully booked for the whole of the summer and we are being kept very busy by the many requests for servers and support.

This is an amazing write up, Chrissy! I have a ton of questions, but I'll start with these three:

  1. Can you share more about the types of devices (phones, tablets, power banks) you have? How did you decide which ones to get?

  2. Are the training materials something you could share with the ODK community? We are launching a docs effort at https://github.com/opendatakit/docs and if we can combine resource, we'd be able to save each other a ton of work.

  3. What is your biggest pain point with growing the work you are doing at LSHTM? Is it funding? Is it the software? Is it training?

Hi Yaw - I can answer a few of these!

  1. We were lucky to be donated a few Android One Devices (LG phones) and then we opted to buy some Google Nexus tablets. Initially the device choice was based on a few key considerations - goodish battery life, need for reasonable GPS, relatively small to make portable in the field, not too expensive so we could buy as many as we could from our small fund of money. We also bought a bunch of power banks for teams to use and also some WiFI dongles so a single sim-card could be used to link multiple devices to our LSHTM servers in the field.

  2. We have developed some training materials. They are mostly freely available at odk.lshtm.ac.uk - some would need adjustment because the server setting side of things are obviously tweaked for our server setup

  3. We have a few pain points! Funding actually not the biggest one - servers are basically minimal internal cost and most projects either use our device bank or buy some from their budgets. There are issues around bi-directional data flow, correcting data in the field and collecting data in line with Good Clinical Practice guidelines. We hope that ODK 2.0 may address some of these.

Overall it has been a real success - 75 projects in the 2 years since we launched!
