New Uganda study shows Oxygen Access increase among neonates & children in Hospitals
A new study in Uganda has shown a significant increase in oxygen access and pulse oximetry among neonates and children in health facilities.
Preliminary findings published in The Lancet, the world’s highest-impact medical and academic journal show the positive impact of a diverse oxygen systems strengthening intervention on diagnosis, oxygen therapy use, and mortality rates.
Titled; “Improving Effective Coverage of Medical Oxygen Services for Neonates and Children in Health Facilities in Uganda: A Before-After Interventional Study,” the study shows that large-scale improvements in hospital oxygen services are achievable in a relatively short timeframe and have great potential for impact.
The study was led by Dr. Freddie Ssengooba, an Associate Professor of Health Policy Planning and Management, at the School of Public Health and Dr. Freddy Eric Kitutu, a Senior Lecturer of Health Systems Pharmacy both co-chairs of the Lancet Global Health Commission on Medical Security. Other researchers on the study include Hamish Graham from the University of Melbourne, Yewande Kamuntu, Blasio Kunihira, Santa Engol, Jasmine Miller, Absolom Zisanhi, Dorcas Kemigisha, Lorraine Kabunga and Felix Lam all from Clinton Health Access Initiative, Dr. Charles Olaro from Uganda’s Ministry of Health and Dr. Harriet Ajilong from the Uganda Paediatric Association.
From June 2020 to June 2022, an intervention study assessed neonates and children at 31 government health facilities in Uganda’s Busoga and North Buganda regions, located at altitudes of 1100-1400 meters. The primary outcome measured the proportion of patients with documented pulse oximetry on admission.
Secondary outcomes included patients with severe hypoxaemia (SpO2 < 90%) receiving oxygen, overall oxygen usage, and appropriate oxygen usage. The study’s primary effectiveness analysis compared pulse oximetry coverage before and after the intervention, incorporating a 4-month washout period. The analysis utilized mixed-effects logistic regression, adjusting for clustering at individual facilities, age (child versus neonate), and sex (male versus female).
Researchers analyzed 64,562 patients (25% neonates) and observed a significant rise in pulse oximetry coverage during the intervention period, increasing from 24% to 88% with an adjusted odds ratio of 40.1 (95% confidence interval: 37.4 to 42.9).
They also observed better oxygen coverage for children and neonates with low oxygen levels, increasing from 40% to 71%, with an adjusted odds ratio of 3.81 (95% confidence interval: 3.26 to 4.46).
Additionally, there was a slight increase in overall oxygen usage, rising from 8% to 11%, with an adjusted odds ratio of 1.95 (95% confidence interval: 1.79 to 2.13).
“Improvements were relatively greater in smaller facilities and for children (versus neonates). We estimated additional patients served and lives saved in the post-intervention period using observed effect estimates in this and other studies,” reads the study.
With these findings, researchers are calling on governments in low-income and middle-income countries to create oxygen plans and invest in proven solutions, like incorporating pulse oximetry in regular hospital care, and providing clinical as well as biomedical mentorship and support.
For all age groups, medical oxygen is essential for both acute and chronic health problems. Scientific evidence suggests access to medical oxygen services that are safe, economical, and appropriate is essential for improving overall health and achieving Sustainable Development Goals. Unfortunately, inadequate or inconsistent oxygen supplies present challenges for many low- and middle-income nations, particularly for small medical facilities in underserved areas.
Disruptions in the oxygen supply during the COVID-19 pandemic caused excessive deaths, which predominantly affected countries with low to middle incomes. According to a 2021 study, half of the COVID-19 patients who died in 64 critical care units across ten African countries did not receive the required medical oxygen.
The study was funded by a grant from the Bill and Melinda Gates Foundation (BMGF) and ELMA Philanthropies to the Clinton Health Access Initiative (CHAI) and approval from Makerere University School of Health Sciences Research and Ethics Committee, and the Uganda National Council of Science and Technology.

The Makerere University College of Health Sciences (MakCHS) on July 10, 2026, welcomed senior six science students from Ngora High School and Wiggins Secondary School to an inspiring Career Fair aimed at guiding them on careers in health sciences and introducing them to the wide range of academic programmes offered by the College.
The event brought together students pursuing Physics, Chemistry, Biology (PCB) and Biology, Chemistry, Mathematics (BCM), providing them with a unique opportunity to interact with the College leadership, tour laboratories and teaching facilities, and learn first-hand about careers in medicine and other health science disciplines.
Welcoming the students, the College Principal, Prof. Bruce Kirenga, described the College of Health Sciences as one of Africa’s oldest and most distinguished medical schools, with a legacy spanning more than a century.
“We started in 1924, making us one of the oldest medical schools on the continent. You have made the right decision to visit Makerere, and we are delighted to welcome you,” he said.
Prof. Kirenga commended the school administrators and teachers for organizing the visit, noting that exposing learners to university environments early helps them make informed career choices. He explained that the College introduced the Open Day concept after receiving numerous requests from schools seeking career guidance visits.
He congratulated the students for choosing science subjects, describing science as the foundation for solving society’s most pressing challenges.
“You have already made one of the most important decisions by choosing to become scientists. Even more importantly, you have chosen life sciences—a field dedicated to preserving and improving life,” he remarked.
The Principal emphasized that careers in life sciences extend far beyond medicine, encouraging students to remain open-minded as they consider their future.
“Everything that has life requires professionals to keep it healthy—from human beings and animals to crops and the environment. The opportunities are immense, including agriculture, veterinary medicine, biomedical sciences, public health and many other emerging fields.”
He also advised students not to limit themselves to only one academic programme during university applications, recalling instances where highly qualified students narrowly missed admission because they selected only one course.
“Remain open to the opportunities available. Medicine is an excellent profession, but there are many other programmes that are equally rewarding and are shaping the future of healthcare and scientific innovation,” he said.
Prof. Kirenga further encouraged the students to embrace lifelong learning, reminding them that scientific knowledge remains valuable regardless of the career path they eventually pursue.
Addressing the students, the Dean of the School of Medicine, Prof. Annette Nakimuli, acknowledged the growing competition for admission into medical programmes and urged learners to work hard while keeping an open mind about the diverse opportunities available within health sciences.
She explained that admission into the Bachelor of Medicine and Bachelor of Surgery (MBChB) programme has become increasingly competitive due to the rising number of high-performing applicants.
“This year we witnessed unprecedented competition for government sponsorship, with many applicants scoring triple A at Advanced Level and outstanding grades at Ordinary Level. That tells you that you must prepare yourselves to excel academically,” she said.
Prof. Nakimuli noted that while many students aspire to become medical doctors, the health sector today offers numerous innovative programmes that are equally important.
“There are many programmes that parents, teachers and students are still not familiar with. Biomedical Engineering, for example, is one of the exciting fields driving the future of healthcare, yet many students overlook it because they focus only on medicine.”
She encouraged students to explore emerging disciplines that combine medicine, engineering, technology and research, noting that the future of healthcare increasingly depends on multidisciplinary professionals.
The Dean also introduced students to the structure of the School of Medicine, explaining that it comprises twelve academic departments and two specialised units covering a broad spectrum of clinical disciplines, including Internal Medicine, Surgery, Obstetrics and Gynaecology, Orthopaedics, Ophthalmology, Ear, Nose and Throat (ENT), Family Medicine, Anaesthesia and Critical Care, among others.
She explained that students are trained by specialists across these disciplines to become competent general practitioners before pursuing further specialization.
Prof. Erisa Mwaka, the Chair of the Department of Human Anatomy, shared with the students about the School of Biomedical Sciences (SBS). He said the school is one of the four schools that make up the Makerere University College of Health Sciences (MakCHS). As the foundation of medical education, the School provides students with a comprehensive understanding of the biological and molecular sciences that underpin modern healthcare, disease prevention, diagnosis and treatment.
The School comprises several departments, including:
- Human Anatomy
- Biochemistry
- Physiology
- Pharmacology and Therapeutics
