Phone-based HIV support system repurposed for COVID-19 monitoring in Uganda

People entering Uganda have been required to quarantine for 14 days as part of the country’s lockdown measures, during which time they are monitored by the Ugandan Ministry of Health for development of COVID-19 symptoms.

Cambridge researcher Dr Rosalind Parkes-Ratanshi and her team have been helping the Ministry monitor and support quarantined individuals using a voice and SMS messaging system, Call for Life Uganda (C4LU). ̽��ֱ��tool was rapidly adapted for COVID-19 by Parkes-Ratanshi, who is based jointly at Cambridge’s Institute of Public Health and leads the Academy for Health Innovation at Infectious Diseases Institute, Makerere ̽��ֱ��, Uganda.

̽��ֱ��C4LU system regularly phones quarantined individuals to request they report any symptoms. ̽��ֱ��automated system then generates symptom reports and anything of potential concern is flagged to healthcare professionals for triaging. This eases the burden on healthcare workers of widespread check-ups in person or by phone.

Parkes-Ratanshi and colleagues at the Infectious Diseases Institute have been using the tool for the past four years to monitor HIV patients, in collaboration with Janssen: Pharmaceutical companies of Johnson & Johnson. When the coronavirus pandemic reached Uganda, the team rapidly repurposed the system they had developed, re-scripting for COVID-19 and recording the messages in 11 of the languages spoken in Uganda.

“ ̽��ֱ��total number of COVID-19 cases in Uganda has been low so far, with just over 1,000 cases across the whole country,” says Parkes-Ratanshi, who is currently based in Uganda. “Almost all cases seem to be linked to returning travellers and so the quarantine system and lockdown have been vital to slow the spread of the pandemic.”

Currently, the team are monitoring around 250 people using C4LU, with a total of 599 having participated so far. “Only a very small number of people have then needed to be tested for COVID-19, which shows the benefits of having a tool that can take pressure off the health system by reducing unnecessary visits,” she says.

Although Uganda has been fortunate in not suffering the scale of cases seen in some countries, Parkes-Ratanshi is mindful that there could be a future surge in infection. “We could see a time when regular monitoring on a wider scale would be beneficial. A system like this could reduce the number of individual calls coming in to the Ministry of Health – it could take some of the burden.”

So far, the team has focused on implementation – getting the system up and running, and triaging for possible COVID-19 cases that require confirmatory tests. They are now adding a research component, so that they can learn more about the impact of the technology, with funding from Cambridge ̽��ֱ��’s Global Challenges Research Fund QR.

̽��ֱ��team has been asked by the Ugandan Ministry of Health to add a layer of mental health support to the tool, adds Parkes-Ratanshi. “Once you’ve gone through your symptom reporting, you might then be asked a couple of screening questions about anxiety or mental health issues. Depending on the answer, we could then offer mental health support for those people who may not need active care or active testing, but have got anxiety or mental health issues related to COVID. We think that this will also be exceedingly important to help in a situation where the health care system is very stretched.”

Crucially, the technology is appropriate to the context, says Parkes-Ratanshi: “Around 75% of people have phones in Uganda, so phone-based technology seems to be a very good way of doing this kind of public health monitoring. But it would be no good taking say a smartphone app developed in the UK and thinking it would work for Africa. Even those people who’ve got smartphones may not have access to the internet on the day they need it. So our technology is developed to work on low-cost mobile and analogue phones.”

C4LU itself is based on an open source digital system developed originally for tuberculosis patients by Janssen. “Time and resources are limited in sub-Saharan Africa. We don’t really want to be experimenting with new stuff in a pandemic, which is why we’re glad to apply our experience using this tool for HIV to COVID-19.”

Rosalind Parkes-Ratanshi is supported by several of Cambridge’s interdisciplinary networks and initiatives – Public Health, Cambridge-Africa, Infectious Diseases and Global Challenges.

How you can support Cambridge’s COVID-19 research

A cost-effective phone-based system developed by a Cambridge researcher and her Ugandan colleagues to support HIV patients has been rapidly adapted by the team to help the Ugandan Ministry of Health monitor those in quarantine during the coronavirus pandemic.

We could see a time when regular monitoring on a wider scale would be beneficial. A system like this could reduce the number of individual calls coming in to the Ministry of Health – it could take some of the burden

Meeting local needs: how the Fens can learn from research in Africa

cjb250 — Fri, 03 Mar 2017 09:59:00 +0000

When Dr Rosalind Parkes-Ratanshi first arrived in Africa in 2003, the situation regarding HIV – her specialism – was “just awful”, she says. We’re all familiar with the devastating images of emaciated and very sick African patients dying in hospital wards, but to see this first hand, she says, was truly shocking.

At the time, antiretroviral therapy (ART), which in developed countries were helping patients manage their condition and limit the spread of the disease, were not widely available in Africa. People were dying from opportunistic infections which most of us were not at risk of or could fend off with adequate treatment.

She had been practising as a doctor in London and had seen HIV treatment transformed. No longer did it carry a death sentence; for the majority of people, if diagnosed early enough, it could now be managed as a chronic condition, like for example diabetes.

Seeing and hearing about the situation in sub-Saharan Africa, which carries by far the greatest global burden of the disease, Parkes-Ratanshi headed to Uganda to carry out a PhD at the UK Medical Research Council/Uganda Virus Research Institute. She was looking at the treatment of cryptococcal meningitis, a potentially life-threatening fungal infection of the brain and spinal cord in Masaka in the rural South West of the country.

Turning the tide

Parkes-Ratanshi saw the tide begin to turn on HIV. Masaka Regional Referral Hospital and ̽��ֱ��AIDS Support Organisation (an NGO) where she worked were among the first to trial the rollout of ART. ̽��ֱ��government and the president had recognised the severity of the problem very quickly and sought help from the international community. It also promoted public health messages around ‘ABC’ – abstinence, be faithful, wear a condom. At its peak, around 15% of Ugandans were HIV-positive – this figure has now fallen to just over 7%.

Nowadays, a person living with HIV in Uganda should be able to manage their HIV as in the West. In fact, the national and international efforts to control the epidemic have been so effective that a cohort of infected individuals has been recruited to help researchers study how people live with their chronic infection.

“We used to look at cohorts to try to understand what patients were dying from,” says Parkes-Ratanshi, “but now we have patients who have been on ART for over ten years. They’re no longer dying from infections related to a poor immune system, but face other issues such as treatment fatigue, stigma and non-communicable diseases like cardiovascular disease and cancers.”

Parkes-Ratanshi is working with the cohort as part of her involvement with the Ugandan Academy for Health Innovation and Impact, of which she is Director. ̽��ֱ��Academy is a joint initiative between Janssen, the pharmaceutical companies of Johnson & Johnson, the Ugandan Ministry of Health, the Infectious Diseases Institute in Uganda and the Johnson & Johnson Corporate Citizenship Trust to address unmet needs in HIV and TB. It is there, she says, to ensure that the outcomes of clinical research are embedded in health policies that benefit the population. “It’s more translational than translational! It’s not lab to clinic, it’s clinic to population.”

One of its flagship programmes is Call for Life™, a randomised controlled trial which aims to promote healthy behaviours and adherence to drug regimens amongst the HIV cohort through the use of mobile phone technology. Participants receive a call at certain times of the day and are offered advice on adherence, health tips and reminders to attend clinic. This simple, cost-effective intervention could help patients manage their infection without over-reliance on the country’s limited resources.

“ ̽��ֱ��thing I’m particularly interested in is this concept of ‘differentiated care’,” she adds. “How can we offer a light touch for those that are doing well and are taking their drugs well and responding well to treatment, and save the resources for those that really need extra help – they’ve only just been diagnosed, or they’re adolescents or pregnant or kids, for example.”

̽��ֱ��Academy is about more than just conducting research, however. It is about providing much needed skills and training to researchers across Africa. It works with the Infectious Diseases Institute,which has provided training through short courses to some 16,000 clinicians and scientists across Africa, and is developing a series of online courses using a smartphone and desktop platform so that scientists/ clinicians who are unable to attend in person can still benefit.

Learning from each other

In 2015, Parkes-Ratanshi returned to the UK and took up a position as a lecturer at the Cambridge Institute of Public Health. She has not given up her ties to Uganda – she is still Director of the Academy – but felt this was the right time to increase links with the UK. There were, she says, two main reasons that influenced her decision.

In Uganda, HIV is treated using a standardised approach using national pathways and limited, but effective, treatments. If you’re a patient with HIV, you get the first line treatment recommended by the Ministry of Health and WHO; if and when that fails, you receive the second line treatment, and so on. In the UK, however, treatment is individualised to a patient so that they receive maximum benefit with minimum side effects. “In order to know what the options are, I need to be clinically ‘on the ball’,” she says. “I need to be up to date with clinical skills from an international perspective to know what the opportunities are for research and clinical care in Uganda.”

But it is the strengths of Cambridge’s research networks – Cambridge Institute of Public Health, Cambridge-Africa and Cambridge Infectious Diseases to name but a few – that hold real appeal.

“When you’re working in a resource-poor setting like Uganda, you are thinking about the immediate problems facing you and there aren’t huge amounts of basic science and translational medical research. There are initiatives like the Ugandan Academy and Cambridge-Africa that are looking to change this, trying to bring up a generation of basic scientists, but at the moment, that capacity isn’t there.

“If we’re going to think of ways to benefit the widest possible group, we’re going to need to make collaborations with other researchers in other areas. For somebody like me, those cross-university networks are vitally important. That’s the only way we’re going to be able to solve problems for our resource-limited environments.”

Parkes-Ratanshi is now working with Professor Carol Brayne, Director of the Cambridge Institute of Public Health, to look at how evidence generated in a well-resourced part of the world might be linked with that from lower-resource settings. In the spirit of initiatives such as Cambridge-Africa, this isn’t about making assumptions about research priorities and carrying them out on particular populations. “It’s very much about community participation,” she explains, “It’s about going to the communities and asking them ‘What are your priorities around ageing? What are you interested in? What’s concerning you on a daily basis?’ and then co-developing research that’s relevant to them.”

One might assume that when she refers to “lower-resource settings”, she means Africa. Not necessarily. “There’s great inequality even within the UK,” she says. And so, while they have identified sites in Uganda and South Africa, as well as in Bali, they are also looking at areas in the Fenlands around Cambridge, where deprivation levels are high.

And in a sense, this is one of the real benefits of encouraging collaborations between geographically and economically diverse areas of the world: everyone has something to give, everyone has something to learn. “When you’re in a poorly-resourced setting, you generate ideas and innovations that might help in a resource-rich setting as well as your own. And who knows, some of the ideas that come out of this might be helpful in the future as the UK itself becomes more resource-limited.”

Dr Rosalind Parkes-Ratanshi is used to working in resource-poor settings. She spent over a decade on the frontline fighting HIV and AIDS in Uganda. Now in Cambridge, she plans to focus on working in areas of deprivation – in Africa and south east Asia, but also much closer to home.

We used to look at cohorts to try to understand what patients were dying from, but now... they’re no longer dying from infections, but face other issues such as treatment fatigue and stigma
