Mak Researchers Design National Drowning Prevention Strategy
By Joseph Odoi
Makerere University researchers under Trauma, Injuries and Disability (TRIAD) Unit) have designed a national drowning prevention strategy. This strategy comes at a time when there is sky rocketing cases of drowning in Africa.
Globally, drowning is the third leading cause of unintentional injury death; accounting for 7% of all injuries. Over 90% of the estimated 322,000 annual global drowning deaths occur in low-and middle-income countries.
Although the burden of drowning is believed to be highest in the WHO-African region, data collection and surveillance for drowning in African countries is limited.
In bid to contribute to data driven interventions, Makerere University researchers carried out a study aimed at establishing the availability of drowning data in district-level sources and understanding the reporting of and record keeping on drowning in Uganda.
As part of the study titled: Drowning in Uganda; examining data from administrative sources, researchers engaged various health stakeholders who shared their experiences about drowning and how it can be prevented in communities.
It is upon that background that scholars designed a contextual appropriate strategy for drowning prevention in Uganda under the project titled; Drowning in Uganda; examining data from administrative sources.
According to the researchers, this drowning strategy is first ever in Uganda. ‘’it will be a national document that will guide all the efforts on drowning prevention in the country; and will avoid non-coordinated activities aimed at prevention of drowning. the strategy will also provide for monitoring and evaluation of all activities and interventions for drowning prevention in the country since there will be a government lead agency tasked with this responsibility’ ’explained Mr. Fredrick Oporia who is part of the study team
STRATEGIES TO PREVENT DROWNING
In this study published on semantics scholar among other journals, the researchers came up with the following strategies to counter drowning;
• Setting and enforcing safe boating regulations. • Providing incentives that encourage adherence to boating regulations related to not overloading transport boats and increasing enforcement of boating regulations. • Ensuring boats are fit for purpose and increasing regular inspection of the seaworthiness of boats. • Improving detection and dissemination of information about the weather. • Supporting increased availability and use of lifejackets through subsidy, lifejacket loaner programs, and free lifejacket distribution programs. • Increasing sensitization about safe boating practices, the importance of wearing lifejackets, and limiting alcohol and illicit drug use when boating. Community members, especially children, are vulnerable to drowning in unsafe water sources such as ditches, latrines, wells, and dams. Potential interventions could include: • Modifying access to wells and dams to prevent children or adults from falling in. • Installing boreholes and pumps to enable community members to draw water safely.
Providing safe rescue and resuscitation training to community members and conducting refresher trainings. • Developing and providing low-cost rescue equipment such as boat fenders (rubber and ropes tied to boat on all sides that can assist in the immediate rescue of individuals) and buoyant throwing aids.
To enable ongoing design, implementation, and evaluation of drowning prevention efforts, the researchers note that it is essential to collect data on drowning incidents. Reporting of and record keeping on drowning in Uganda should also be improve according to the researchers namely; Tessa Clemens, Frederick Oporia, Erin M Parker, Merissa, A Yellman, Michael F Ballesteros and Olive Kobusingye
Other Potential interventions highlighted by the researchers include: • Providing records officers with proper training, equipment, and appropriate storage facilities. • Sensitizing the public on the importance of reporting all drowning cases to authorities.
As part of their study findings, the researchers noted that; A total of 1435 fatal and non-fatal drowning cases were recorded; 1009 (70%) in lakeside districts and 426 (30%) in non-lakeside districts.
Of 1292 fatal cases, 1041 (81%) were identified in only one source. After deduplication, 1283 (89% of recorded cases; 1160 fatal, 123 non-fatal) unique drowning cases remained. Data completeness varied by source and variable.
On demographics, fatal victims were predominantly male (85%), and the average age was 24 years. In lakeside districts, 81% of fatal cases with a known activity at the time of drowning involved boating.
What were people doing when they drowned?
Activity at the time of drowning in lakeside districts and non-lakeside districts
• Overall, boating was by far the most common activity that people were engaged in at the time of the drowning incident.
• Other common activities were collecting water/watering cattle and travelling on foot.
• The most common activities that people engaged in prior to drowning were similar in lakeside and non-lakeside districts. However, in non-lakeside districts, more drowning deaths occurred as a result of collecting water or watering cattle than as a result of boating in those districts.
• Almost half (48%) of all drownings occurred while the person was engaged in an occupational activity.
Of the 1,063 people who died from boating-related drowning or suffered a severe boating related drowning incident but survived, 1,007 (95%) were not wearing a lifejacket at the time of the incident.
Bathing in water bodies: Study participants indicated that drowning sometimes occurs when people are bathing in lakes, ponds, swamps, and valley dams. People can unexpectedly slip into deep water from shallower areas or rocks.
Crossing flooded rivers and streams:
Attempting to cross flooded rivers and streams during the rainy season was another cause of drowning identified by study participants.
“Currently, people cross from makeshift bridges such as that of round poles. When the river overflows, it covers them. So, you can’t see them; so, you just start guessing: ‘the pole might be here or there’ and in case your guess is wrong, you automatically drown and you will be gone.” an Interview respondent in Kabale district explained
Delayed rescue attempts: Study participants identified the importance of timely rescue and resuscitation to prevent death from drowning. However, they also indicated that community members lack knowledge on how to rescue someone who is drowning.
Alcohol use: Several participants identified alcohol use as a key risk factor for drowning. Participants stated that alcohol use is common, especially in fishing communities. “We have a problem with alcoholism. Many of our colleagues go to the waters when their minds are a bit twisted by the alcohol and on some occasions, this has caused accidents and some of them have drowned just like that.” – Interview respondent, Nakasongola district.
When asked on strategies of preventing drowning, participants suggested the following strategies for preventing drowning:
• Provide affordable and high-quality lifejackets to all water transport users and fishing communities. • Increase sensitization of fishermen and all water transport users on the importance of using lifejackets and avoiding alcohol while boating. • Provide subsidies for large and motorized boats that can be used for safe water travel and fishing to replace small and low-quality boats that are currently in use.
Inspect boats regularly to ensure they are in good travelling condition. • Recruit and deploy more marine police units on all major water bodies to enhance security and quick response to drowning incidents. • Install boat fenders (rubber and ropes tied to boat on all sides) to assist with the immediate rescue of individuals who are involved in a drowning incident. • Provide frequent and safe ferry services to enable water travellers access to safe transportation across rivers and lakes. • Avoid fishing during the moonlight periods to minimize hippopotamus attacks which are more frequent at that time.
“I think these fishermen really need lifejackets for their work and also need to be sensitized on how to manage the engine of the boats that they use for their work. In most cases, these men just learn how to use these boats without having been trained first.” – Interview respondent, Rakai district. Swimming and basic rescue skills said
Moving forward, the researchers recommend that since; drowning is a multisectoral issue, and all stakeholders (local and national government, water transport, water sport, education, fishing, health, and law enforcement) should coordinate to develop a national water safety strategy and action plan.
MORE ABOUT THE STUDY
The study was conducted in 60 districts of Uganda for a period of 2.5 years (from January 1st, 2016 to June 30th, 2018). In the first phase, records concerning 1,435 drowning cases were found in the 60 study districts.
In the second phase, a total of 2,066 drowning cases were identified in 14 districts by community health workers and confirmed through individual interviews with witnesses/family members/friends and survivors of drowning. This work was funded by Bloomberg Philanthropies through the CDC Foundation

Makerere Hosts Inaugural Falling Walls Lab Competition as Innovators Pitch Solutions to National Challenges
Students and researchers from Makerere University and other institutions pitched 12 innovations addressing challenges in healthcare, clean energy, agriculture, waste management and community resilience during the inaugural Falling Walls Lab Kampala, held at the School of Public Health Auditorium, Makerere University.
The competition brought together emerging innovators to present solutions to practical challenges through a three minute pitch, followed by questions from a panel of judges.
Modelled on the Falling Walls format that originated in Berlin, the event required each participant to identify a “wall” a problem or barrier, and demonstrate how their innovation seeks to break it down.
Mudhasi wins with newborn jaundice screening device
Andrew Mudhasi of Makerere University emerged as the overall winner with a score of 90 per cent for a low cost medical device designed to improve newborn jaundice screening across different skin tones.
Mudhasi explained that the device uses optical sensor technology and a skin tone targeting algorithm to provide a rapid reading, with the aim of helping nurses and clinicians identify jaundice more efficiently.
During questions from the jury, Mudhasi said the device had not yet been tested on actual babies but had undergone laboratory testing using simulated skin tones.
He reported an accuracy rate of 94 per cent when the device was compared with laboratory spectrophotometers.
The innovation is intended initially for use in clinics and hospitals, with Mudhasi saying the team is also considering a version that could eventually allow mothers to screen babies at home.
Mudhasi’s innovation has previously received recognition at the African Business Concept Challenge and the iF Design Student Award, according to his presentation.
Rhonda’s innovation tackles diaper waste
Rhoda John of the University of Nairobi emerged in second place with 89.6 per cent for an innovation addressing the problem of used diaper waste.
Under the theme “Breaking the wall of diaper waste and drug soils,” Rhonda explained that her team extracts sodium polyacrylate, the absorbent polymer found in diapers, and replaces the sodium with potassium.
The resulting potassium based superabsorbent material is designed to act as a “water battery” in soil by absorbing and retaining water for plants during dry periods.
John said testing showed a 99 per cent increase in germination and a 23 per cent increase in drought resistance.
The innovation also seeks to reduce the amount of used diapers ending up in landfills and the environmental effects associated with their decomposition.
During the question and answer session, John explained that her team was working with government environmental officials in Nairobi on a pilot collection system to address the challenge of gathering used diapers at scale.
Mahera takes third place with herbal peptic ulcer treatment
Stuart Mahera of Makerere University finished third with 86.2 per cent for a herbal formulation targeting peptic ulcers.
Presenting under the theme “Breaking the wall of Nature and Modern Medicine,” Mahera argued that conventional treatment for peptic ulcers can involve multiple medicines and may be associated with side effects and antimicrobial resistance.
His proposed formulation, MARAC capsules, is intended as a monotherapy, combining properties required for peptic-ulcer treatment in a single capsule.
Mahera said his team had carried out quality control work, including characterisation and dose quantification, and had conducted preclinical trials on laboratory mice.
He also told the jury that an application had been submitted to the National Drug Authority as the team awaits the next stage of the regulatory process.
According to Mahera, the proposed seven day treatment would cost about Shs21,000, compared with the existing 14 day treatment approach.
Innovators present solutions to practical challenges
The remaining presentations covered a wide range of challenges.
Esther Nakungu of Utamu University presented Agri-Track, a digital record keeping solution intended to improve visibility, accountability and management of farm operations and financial information.
Dr. Jimmy Chachiga, a Makerere University participant, presented a solar photovoltaic cooker with a heat storage system designed to provide a cleaner and more reliable cooking option during both sunny and non sunny periods.
His presentation focused on reducing dependence on biomass fuels and addressing the challenges associated with intermittent solar energy.
Abdul Noor Luttamaguzi, a PhD student and senior government fisheries officer, presented a mobile application aimed at helping fish farmers and extension officers report, track and manage disease outbreaks.
Henry Duke Tamale presented a herbal cream targeting antibiotic resistant biofilm infections associated with diabetic foot ulcers.
Marvin Seruwu proposed adapting existing near infrared brain monitoring technology to help detect extra-axial brain bleeds in health facilities where access to CT and MRI equipment is limited.
His proposal seeks to repurpose existing technology towards a diagnostic need that could be particularly important in settings where advanced imaging facilities are not readily available.
Kennedy Kisame presented a poultry alert and diagnosis system combining satellite weather information with computer vision disease detection. The proposed system could be accessed through a smartphone application, SMS or USSD, making it potentially usable by farmers with limited internet access.
Frank Atwiine proposed a solar powered mobile diagnostic van designed to bring ultrasound and other diagnostic services closer to rural communities.
Johnson Makmot, a software and blockchain developer, presented a platform that combines GPS tracking and blockchain-based tokens to incentivise and verify plastic-waste collection in Kampala.
Dr. Nelson Ndugu, from a partner university, presented an artificial intelligence tool designed to translate agricultural research publications into local Ugandan languages and generate voice notes for radio-based extension delivery.
The final presentation came from Dr. Juliet Akola, a Ugandan post doctoral researcher at Mangosuthu University of Technology in South Africa.
Akola presented a community digital resilience initiative focused on mapping risks in Kampala’s informal settlements, including flooding, fire, poor sanitation, waste management and inadequate infrastructure.
Her proposal seeks to combine local community knowledge with geographical information systems and link identified risks to action plans involving municipalities and other stakeholders.
Nawangwe calls for more investment in innovation
Closing the event, Prof. Nawangwe congratulated all the participants and described their presentations as an important beginning for Makerere University, Uganda and the wider region.
Drawing on his experience attending the Falling Walls conference in Berlin, the Vice Chancellor said initiatives of this nature are important because innovation will play a major role in determining the future of countries.
He encouraged participants to make their pitches more precise by clearly identifying the problem they are addressing, explaining their proposed solution and demonstrating what they have already achieved.
Prof. Nawangwe also welcomed the participation of innovators from other universities and countries, noting that the Kampala event had attracted participants beyond Makerere.
He thanked the Africa Office of the Falling Walls Foundation for its role in bringing the initiative to Makerere and encouraged continued support for innovation.
The Vice Chancellor further linked innovation to Uganda’s growing youth population and the need to develop home-grown solutions to address challenges such as youth unemployment.
The inaugural Falling Walls Lab Kampala ultimately provided a platform for innovators to move ideas beyond the classroom and laboratory and demonstrate how research, technology and creativity can be applied to challenges affecting communities.
