Using drones in healthcare supply chains is now proven
Healthcare for Africa’s rural and remote communities is demanding. Supply chains can be long and time-consuming. Drones can help, and while they may have been a bit fanciful as an idea, they’re now proven. Two companies are doing it.
Zipline, a global drone company, has a regular service in Rwanda. It delivers drugs and vaccines to remote communities. The steps to delivery are:Health workers use text message to the Zipline distribution centre to order the medical products they needItems are pack and prepared for flight in a few minutes, maintaining cold-chain and product integrityConfirmation to health workers that their order launchesDirect delivery at over 100 kmh, faster than other transport modes, delivered gently by parachute into a designated area the size of a few parking spaces, obviously with no pilot Health workers receive a text message notifying them that a delivery is completed.
In April 2018, the UPS Foundation announced it was expanding its work with Gavi, the Vaccine Alliance and Ziplineto to use drones to deliver blood and medicines to Rwandas’ remote communities. Since October 2016, the partnership has made over 4,000 drone deliveries of over 7,000 units of blood to remote hospitals across the country. UPS says it’s the world’s first national medical drone delivery network, and is being developed throughout Rwanda.
In Tanzania, an article in UAS Vision says DHL, a global delivery services, has completed a trial using Wingcopter to deliver medicines over 60 km in 40 minutes from Mwanza to Nansio district hospital on the island of Ukerewe in Lake Victoria. Over 160 proving flights were completed. It takes about six hours to deliver by road.
Now, 400,000 people living in Ukerewe District now have healthcare access in hours, not days. Three other districts are served too, totalling over 10 million people. It follows the success of DHL’s test to ensure reliability of deliveries beyond line-of-sight and the return of the drone.
These services show that drones should be a routine component of Africa’s healthcare supply chains. While remote services are current priorities, urban areas will benefit too as drone technology develops.

Drones and mHealth help to combat global diseases
As drones expand their role in healthcare, they’re starting to help in dealing with global diseases. Their impact’s combined with the mobiles’ role. An article from the London School of Hygiene and Tropical Medicine describes some of the initiatives and benefits.
Drones can be seen as a subset of robots. They’re being used in Malaysian Borneo to map deforestation after a surge in human cases of ‘monkey malaria’, a strain of the disease caused by the parasite Plasmodium knowlesi that normally only affects macaques. It’s commonly misdiagnosed as P. malariae, a mild form of malaria because it looks similar under the microscope. The monkey form is severe in humans and has a high fatality rate.
Research has found that people in villages with significant deforestation around them are more likely to be infected with P. knowlesi. To measure changes, drones with cameras picture and map changing forest landscapes. They track monkeys’ movements through GPS collars placed on the animals to identify how they moving in response to deforestation, and especially if they approaching houses and settlements.
The next step’s to develop risk maps to find places and people that are more likely to have P. knowlesi. Forecasts and prediction of the disease will inform malaria control programmes.
In Cambodia, basic mobile phones help women stay free of STIs and use effective contraception after abortions. MObile Technology for Improved Family Planning (MOTIF) has found that sending voice messages reminding women about the importance of continuing with contraception after abortions and offering telephone counselling helped maintain compliance. As mobile phone technology has developed since the trial, the project uses instant messaging, such as WhatsApp, so users can respond at times convenient to them. It’s expected to improve effectiveness.
Africa’s developing mHealth programmes can expect equivalent benefits for patients, communities and their health systems. It’d be valuable to share and learn from their experiences with each other.

Drones can measure some vital signs
Using drones in healthcare’s taking a step from supplies delivery to a clinical role. Two PhD students, Ali Al-Naji and Asanka Perera, at the University of South Australia (UniSA) have used drones to measure heart and breathing rates remotely and accurately. They used advanced image-processing systems and created an algorithm
The initiative grew out of a desire to find a non-contact sensor to replace electrodes used in developing countries to detect vital signs in new-born babies. It can help to reduce infections. Other uses can be in:Nursing homesAreas prone to human infection, such as neonatal wardsWar zonesIsolated communitiesCar accidentsSea rescuesNatural disasters.
A report in BioMedical Engineering Online says the drones detected vital signs in 15 healthy people aged between two and 40 over three years. It can do this simultaneously, and while people are moving.
Sensory Systems Prof Javaan Chahl at UniSA, the project supervisor, told the The Lead, a South Australia news outlet, that the system detects movements in people’s faces and necks to detect heart and breathing rates. Drones in the trials measured the vital signs from three metres. They can also operate further away.
With an emphasis on developing countries, the drone initiative offers Africa and new way to measure heart and breathing rates effectively and efficiently. It’s a paradigm shift from current methods.

Drones can be faster than conventional emergency responses
Drones’ potential’s increasingly linked to supply chains, especially those of the big, online retailers. A report in eHNA described Rwanda’s use in delivering medical supplies. A report by Pew Charitable Trusts identified a new role coming up for drones carrying medical supplies to natural disasters and replacing ambulances that are slow to respond to emergencies in remote areas. This fits Africa’s needs.
Italo Subbarao, Associate Dean of William Carey University College of Osteopathic Medicine, has built three drone prototypes that can support medical care needed for large-scale disasters. A study of the effects of the towering tornado that struck Hattiesburg, Mississippi in 2013 found that emergency medical responders were slowed down by fallen trees, power lines and debris as they tried to reach the injured.
Drones carrying medical supplies, cameras, microphones and interactive goggles can find survivors with an emergency doctor on the scene assessing victims, reading vital signs and administering emergency care. The drone concept doesn’t only fit large-scale emergencies. It can support doctors and other healthcare professionals dealing with serious local emergencies that need specific medical supplies.
The drones’ potential’s confirmed by a Swedish research letter from a team at Karolinska Institutet, published in the Journal of the Journal of the American Medical Association (JAMA). For 18 drone flights, average time to take off for delivery of a defibrillator was three seconds. They were an average of 17 minutes faster than in reaching the location of Out of Hospital Cardiac Arrests (OHCA). While this service carries a specific, pre-loaded drone, it points to the benefits of drones with bespoke payloads ordered by doctors attending a wider range of medical emergencies. It’s a new opportunity for Africa’s healthcare.

Zipline raises US$25m for Africa expansion
Drone delivery firm Zipline has raised US$25 million to expand its African operations. Zipline launched in Rwanda last month. It will deliver emergency blood supplies to 21 clinics in Western Rwanda and response to orders by SMS. There’s a fleet of 15 drones, called Zips. An article in ITWebAfrica says the company will soon be making between 50 and150 emergency flights a day.
Aside from expanding to more African countries and across the world, Zipline also hopes to begin making instant deliveries in the United States in the next six months. It’s collaborating with the White House and the Federal Aviation Administration (FAA).
"The inability to deliver life saving medicines to the people who need them the most causes millions of preventable deaths each year. Zipline will help solve that problem once and for all," said Zipline CEO Keller Rinaudo. "We're building an instant delivery system for the world, allowing medicines and other products to be delivered on-demand and at low-cost, anywhere. This new funding will help make that vision possible much sooner."
Visionnaire Ventures co-founder and managing partner Susan Cho said she was looking forward to what the future holds for Zipline and the people that would benefit from its technology. Zipline's already had a remarkable journey. It’s moved from a prototype to lifesaving blood deliveries in less than two years, no small feat. eHNA is excited to see what’s next.

Rwanda begins medical drone deliveries
Today, Rwanda starts a drone service to deliver blood products to hospitals for emergencies. The next step's to deliver pharmaceutical products. The project's been approved by Rwanda's civil aviation authorities.
Zipline uses fixed-wing drones that automatically fly to destinations in the country. They release small packages attached to parachutes whereby eliminating the need to land at the delivery points before returning.
The technology promises to make deliveries much faster than whats possible by road. eHNA looks forward to reporting on the success of the system and to seeing it implemented in other African countries in the future.

Budgies can reduce drone crashes
As Africa’s skies slowly darken as drones cover the sky delivering drugs to clinics, the lack of illumination may be less worrying than drones falling to the ground from mid-air collisions. This fear may be misplaced, despite being premature.
A study in PLUS ONE by a team at Australia’s University of Queensland, and partly financed by Boeing Defence Australia, investigated how budgerigars avoid mid-air collisions during head-on encounters. Their individual trajectories in a tunnel were recorded using high speed video cameras. Analysis and modelling of the data suggest two simple strategies to avoid collisions. Each bird:Veers to its rightChanges its altitude relative to the other bird according to a pre-set preference.
Both strategies suggest simple rules by which collisions can be avoided in head-on encounters by two agents, whether they’re birds, animals or machines. These findings are potentially applicable to designing guidance algorithms that can drive aircrafts’ automated collision avoidance. They can be used for drones too.
Well, that’s a relief. No need to worry about being hit by a dropping drone. Only drones obscuring Africa’s sun and creating polar nights, and maybe a challenge identified by Demetri Martin, a comedian, “The bird, the bee, the running child are all the same to the sliding glass door.”

Drones v balloons: what’s the outcome?
Africa’s Internet connectivity needs improving. It seems that Google and Facebook might offer two solutions. Google has Project Loon. Facebook has Project Aquila, part of its Connecting the World initiative. If they work, Africa’s eHealth can benefit.
Facebook’s goal’s to provide affordable access to basic internet services to everyone in the world. Its research team already has many leading experts in aerospace and communications technology, including experts from NASA's Jet Propulsion Lab and Ames Research Center. A team from Ascenta has now joined. It’s a UK company bought by Facebook, and whose founders created early versions of Zephyr, the world’s longest flying solar-powered unmanned aircraft. It’s a High Altitude Pseudo-Satellite (HAPS) that fills a capability gap between satellites and drones, and flies above commercial air traffic zones. Airbus says “Replacing one conventional UAV with just one Zephyr would save 2,000 tons of fuel each year.”
Google’s Project Loon aims to overcome the Internet deficit for about two-thirds of the world’s population who don’t have Internet access. It’s a network of balloons traveling on the edge of space, aiming to connect people in rural and remote areas, help fill coverage gaps, and bring people back online after disasters.
Project Loon’s balloons travel in the stratosphere, about 20 km above the Earth. Up there, winds are stratified, each layer varying in speed and direction, so Project Loon’s algorithms determine where its balloons need to go, then moves each one into the wind layer it needs. By moving with the wind, the balloons can form a large communications network.
Loon’s pilot started in June 2013. Thirty balloons were launched from New Zealand’s South Island. They beamed Internet to a small group of pilot testers. It’s expanded since then to include more users over a wider area. It’s next goal’s to set up a ring of uninterrupted connectivity in the Southern Hemisphere.
Either or both of these projects could help to extend Africa’s mHealth and webHealth across more communities. It may not be too long before they’re in place.

Is the sky the limit for drones?
When the Bengali polymath Rabindranath Tagore said “Clouds come floating into my life, no longer to carry rain or usher storm, but to add colour to my sunset,” he couldn’t have envisaged that drones would be too, bringing medical supplies instead of weather and the solar impact on particles in the atmosphere.
As reported in eHNA, Rwanda has set up a service where doctors and nurses in rural areas can use SMSs to order blood and emergency medicine supplies. Drones will then use GPS coordinates to fly to clinics and deliver them by dropping small packages by parachute. An article in The Economist says that other African countries are looking to similar services.
Malawi’s evaluating drones too. A study by the UN Children’s Emergency Fund (UNICEF) looked into the feasibility of using Matternet drones to transport HIV test samples of new born babies. There were two main findings. One was that all 93 flights in the two-week trial period in March were successful. Secondly, the cost of the drones may be more than the cost of using motorbikes. Judith Sherman, UNICEF’s HIV/AIDS chief in Malawi, concludes that “The technology is still immature.”
The next step’s to find a better way to transport lab samples. There may be locations where drones offer the best option, such as islands in Lake Malawi. As technology matures and costs drop, the role of drones seems likely to expand. Rwanda’s

Rwanda's healthcare drones set for takeoff
Starting in June, doctors and nurses in rural areas of Rwanda will be able to order blood and emergency medicine via text messages. Drones, which are part of a new plan designed to save lives, will fly to clinics using GPS coordinates to deliver the ordered goods by dropping the small packages by parachute, says an article in Al Jezeera.
Zipline, the company behind the project, says the aircraft will be capable of making up to 150 deliveries to 21 facilities across the country. Keller Rinaudo, the CEO of Zipline believes Rwanda is the perfect testing ground for this new technology and will support adoption of drones in healthcare in the United States. By operating in a country where the technology serves a real need and will be able to save lives, while accumulating tens of thousands of safe flight hours, the company hopes to secure the case for drones back in the US.
Despite major progress in the last few years, Rwanda remains one of the world's poorest countries and has a long way to go to provide quality health care. Building and running hospitals is expensive, so the government has incentive to be the first in the world to establish a commercial drone-delivery network.
