    (BMJ Open Respiratory Research, 2020) Kwizera, Arthur; Nakibuuka, Jane; Nakiyingi, Lydia; Sendagire, Cornelius; Tumukunde, Janat; Katabira, Catherine; Ssenyonga, Ronald; Kiwanuka, Noah; Kateete, David Patrick; Joloba, Moses; Kabatoro, Daphne; Atwine, Diana; Summers, Charlotte
    Limited data exist on the epidemiology of acute hypoxaemic respiratory failure (AHRF) in low-income countries (LICs). We sought to determine the prevalence of AHRF in critically ill adult patients admitted to a Ugandan tertiary referral hospital; determine clinical and treatment characteristics as well as assess factors associated with mortality.We conducted a prospective observational study at the Mulago National Referral and Teaching Hospital in Uganda. Critically ill adults who were hospitalised at the emergency department and met the criteria for AHRF (acute shortness of breath for less than a week) were enrolled and followed up for 90 days. Multivariable analyses were conducted to determine the risk factors for death.A total of 7300 patients was screened. Of these, 327 (4.5%) presented with AHRF. The majority (60 %) was male and the median age was 38 years (IQR 27–52). The mean plethysmographic oxygen saturation (SpO2) was 77.6% (SD 12.7); mean SpO2/FiO2 ratio 194 (SD 32) and the mean Lung Injury Prediction Score (LIPS) 6.7 (SD 0.8). Pneumonia (80%) was the most common diagnosis. Only 6% of the patients received mechanical ventilatory support. In-hospital mortality was 77% with an average length of hospital stay of 9.2 days (SD 7). At 90 days after enrolment, the mortality increased to 85%. Factors associated with mortality were severity of hypoxaemia (risk ratio (RR) 1.29 (95% CI 1.15 to 1.54), p=0.01); a high LIPS (RR 1.79 (95% CI 1.79 1.14 to 2.83), p=0.01); thrombocytopenia (RR 1.23 (95% CI 1.11 to 1.38), p=0.01); anaemia (RR 1.15 (95% CI 1.01 to 1.31), p=0.03) ; HIV co-infection (RR 0.84 (95% CI 0.72 to 0.97), p=0.019) and male gender (RR 1.15 (95% CI 1.01 to 1.31) p=0.04).The prevalence of AHRF among emergency department patients in a tertiary hospital in an LIC was low but was associated with very high mortality. Pneumonia was the most common cause of AHRF. Mortality was associated with higher severity of hypoxaemia, high LIPS, anaemia, HIV co-infection, thrombocytopenia and being male.

    Antibiotic Prevalence Study and Factors Influencing Prescription of WHO Watch Category Antibiotic Ceftriaxone in a Tertiary Care Private Not for Profit Hospital in Uganda
    (Antibiotics, 2021) Kizito, Mark; Lalitha, Rejani; Kajumbula, Henry; Ssenyonga, Ronald; Muyanja, David; Byakika-Kibwika, Pauline
    Excessive use of ceftriaxone contributes to the emergence and spread of antimicrobial resistance (AMR). In low and middle-income countries, antibiotics are overused but data on consumption are scarcely available. We aimed to determine the prevalence and factors influencing ceftriaxone prescription in a tertiary care private not-for-profit hospital in Uganda. Methods: A cross-sectional study was carried out from October 2019 through May 2020 at Mengo Hospital in Uganda. Patients admitted to the medical ward and who had been prescribed antibiotics were enrolled. Sociodemographic and clinical data were recorded in a structured questionnaire. Bivariate and adjusted logistic regression analyses were performed to determine factors associated with ceftriaxone prescription. Results: Study participants were mostly female (54.7%). The mean age was 56.2 years (SD: 21.42). The majority (187, 73.3%) presented with fever. Out of the 255 participants included in this study, 129 (50.6%) participants were prescribed ceftriaxone. Sixty-five (25.5%) and forty-one (16.0%) participants had a prescription of levofloxacin and metronidazole, respectively. Seven participants (2.7%) had a prescription of meropenem. Out of 129 ceftriaxone prescriptions, 31 (24.0%) were in combination with other antibiotics. Overall, broad-spectrum antibiotic prescriptions accounted for 216 (84.7%) of all prescriptions

    Health systems readiness to provide geriatric friendly care services in Uganda: a cross-sectional study
    (BMC geriatrics, 2019) Ssensamba, Jude Thaddeus; Mukuru, Moses; Nakafeero, Mary; Ssenyonga, Ronald; Kiwanuka, Suzanne N.
    As ageing emerges as the next public health threat in Africa, there is a paucity of information on how prepared its health systems are to provide geriatric friendly care services. In this study, we explored the readiness of Uganda’s public health system to offer geriatric friendly care services in Southern Central Uganda. Methods: Four districts with the highest proportion of old persons in Southern Central Uganda were purposively selected, and a cross-section of 18 randomly selected health facilities (HFs) were visited and assessed for availability of critical items deemed important for provision of geriatric friendly services; as derived from World Health Organization’s Age-friendly primary health care centres toolkit. Data was collected using an adapted health facility geriatric assessment tool, entered into Epi-data software and analysed using STATA version 14. Kruskal-Wallis and Dunn’s post hoc tests were conducted to determine any associations between readiness, health facility level, and district. Results: The overall readiness index was 16.92 (SD ±4.19) (range 10.8–26.6). This differed across districts; Lwengo 17.91 (SD ±3.15), Rakai 17.63 (SD ±4.55), Bukomansimbi 16.51 (SD ±7.18), Kalungu 13.74 (SD ±2.56) and facility levels; Hospitals 26.62, Health centers four (HCIV) 20.05 and Health centers three (HCIII) 14.80. Low readiness was due to poor scores concerning; leadership (0%), financing (0%), human resources (1.7%) and health management information systems (HMIS) (11.8%) WHO building blocks. Higher-level HFs were statistically significantly friendlier than lower-level HFs (p = 0.015). The difference in readiness between HCIIIs and HCIVs was 2.39 (p = 0.025). Conclusion: There is a low readiness for public health facilities to provide geriatric friendly care services in Uganda. This is due to gaps in all of the health system building blocks. There is a need for health system reforms in Uganda to adequately cater for service provision for older adults if the 2020 global healthy ageing goal is to be met.

    Measurement error of mean sac diameter and crown-rump length among pregnant women at Mulago hospital, Uganda
    (BMC Pregnancy and Childbirth, 2018) Ali, Sam; Kusaba Byanyima, Rosemary; Ononge, Sam; Ictho, Jerry; Nyamwiza, Jean; Loro, Emmanuel Lako Ernesto; Mukisa, John; Musewa, Angella; Nalutaaya, Annet; Ssenyonga, Ronald; Kawooya, Ismael; Temper, Benjamin; Katamba, Achilles; Kalyango, Joan; Karamagi, Charles
    Ultrasonography is essential in the prenatal diagnosis and care for the pregnant mothers. However, the measurements obtained often contain a small percentage of unavoidable error that may have serious clinical implications if substantial. We therefore evaluated the level of intra and inter-observer error in measuring mean sac diameter (MSD) and crown-rump length (CRL) in women between 6 and 10 weeks’ gestation at Mulago hospital. Methods: This was a cross-sectional study conducted from January to March 2016. We enrolled 56 women with an intrauterine single viable embryo. The women were scanned using a transvaginal (TVS) technique by two observers who were blinded of each other’s measurements. Each observer measured the CRL twice and the MSD once for each woman. Intra-class correlation coefficients (ICCs), 95% limits of agreement (LOA) and technical error of measurement (TEM) were used for analysis. Results: Intra-observer ICCs for CRL measurements were 0.995 and 0.993 while inter-observer ICCs were 0.988 for CRL and 0.955 for MSD measurements. Intra-observer 95% LOA for CRL were ± 2.04 mm and ± 1.66 mm. Inter-observer LOA were ± 2.35 mm for CRL and ± 4.87 mm for MSD. The intra-observer relative TEM for CRL were 4.62% and 3.70% whereas inter-observer relative TEM were 5.88% and 5.93% for CRL and MSD respectively. Conclusions: Intra- and inter-observer error of CRL and MSD measurements among pregnant women at Mulago hospital were acceptable. This implies that at Mulago hospital, the error in pregnancy dating is within acceptable margins of ±3 days in first trimester, and the CRL and MSD cut offs of ≥7 mm and≥ 25 mm respectively are fit for diagnosis of miscarriage on TVS. These findings should be extrapolated to the whole country with caution. Sonographers can achieve acceptable and comparable diagnostic accuracy levels of MSD and CLR measurements with proper training and adherence to practice guidelines.

    Piperaquine concentration and malaria treatment outcomes in Ugandan children treated for severe malaria with intravenous Artesunate or quinine plus Dihydroartemisinin-Piperaquine
    (BMC infectious diseases, 2019) Byakika-Kibwika, Pauline; Ssenyonga, Ronald; Lamorde, Mohammed; Blessborn, Daniel; Tarning, Joel
    Treatment for severe malaria must be prompt with effective parenteral antimalarial drugs for at least 24 h to achieve fast parasite clearance, and when the patient can tolerate oral therapy, treatment should be completed with effective artemisinin based combination therapy (ACT) for complete parasite clearance and to prevent recrudescence. We evaluated piperaquine concentration and malaria treatment outcomes among Ugandan children treated for severe malaria with intravenous artesunate (AS) or quinine (QN) plus dihydroartemisininpiperaquine (DP), in Tororo District Hospital in Eastern Uganda.

    Prevalence and factors associated with safe male circumcision among Makerere University undergraduate students, Kampala - Uganda
    (Research Square, 2019) Nyamwiza, Jean; Mukisa, John; Ictho, Jerry; Ssenyonga, Ronald; Nalutaaya, Annet; Kawooya, Ismael; Benjamin, Temper; Nagendo, Joanita; Musewa, Angella; Ali, Sam; Lako Ernesto Loro, Emmanuel; Agaba, Bekiita Bosco; Kiwuwa, Mpungu Steven; Kalyango, Joan N.; Karamagi, Charles
    Background Safe male circumcision (SMC) is currently recognized as a preventive strategy in reducing the risk of HIV; however, the prevalence of circumcised men in Uganda is still quite low at 26%. This study aimed to determine the prevalence and factors associated with SMC and among Makerere University undergraduate students, in Kampala Uganda. Methods We conducted a cross-sectional study among 602 participants selected using multistage probability sampling strategy. Pretested semi-structured questionnaires and focus group discussions were used to collect data. Quantitative data were analyzed with Stata 12.0, the prevalence ratio and p-values were calculated. Possible interactions and confounding variables were assessed with the Poisson regression model while qualitative data was analyzed with content analysis. Results The overall prevalence of safe male circumcision among male undergraduates was 58.3% (95% CI: 54.37 – 62.24). Factors associated with SMC prevalence included: safety of SMC procedure (Prevalence Ratio (PR) = 1.13, 95% Confidence Interval (CI): 1.03 – 1.25) and friendly health workers (PR = 0.78, 95% CI: 0.74 – 0.83). The perceived benefits of SMC included hygiene (86.5%, n = 521), reduced risk of HIV transmission (4.5%, n = 26) and reduced risk of penile cancer (45.7%, n = 275) while, the perceived barrier was pain (10.1%, n = 61). The students perceived that SMC recipient’s first sexual partner post-procedure should not be his girlfriend. Most participants in all the focus group discussions perceived SMC increases sexual pleasure. Conclusion The overall self-reported SMC success rate among participants was high, along with the safety of SMC services and friendly health workers as important factors among male students. There is a need for continuous sensitization campaigns and communication strategies to address beliefs about SMC, some related misconceptions, and barriers so as to increase its prevalence.

    Prevalence of Anaemia and Associated Risk Factors among Children in North-western Uganda: A Cross Sectional Study
    (BMC hematology, 2017) Legason, Ismail Dragon; Atiku, Alex; Ssenyonga, Ronald; Olupot, Peter Olupot; Barugahare, John Banson
    Despite the public health significance of anaemia in African children, its broader and often preventable risk factors remain largely under described. This study investigated, for the first time, the prevalence of childhood anaemia and its risk factors in an urban setting in Uganda.A total of 342 children were enrolled. Venous blood samples were collected in EDTA tubes and analyzed using Symex 500i (Symex Corp. Japan). Stool and urine samples were analyzed according to established standard methods. Anthropometric indicators were calculated according to the CDC/WHO 1978 references. Ethical approval was granted.Categorically, the prevalence of anaemia was; 37.2, 33.3 and 11.8% among children aged 1–5 years, 6–11 years and 12–14 years respectively. Overall anaemia prevalence was 34.4%. The risk of anaemia was higher among males than females [(OR = 1.3, 95% CI = 0.8, 2.1), P = .22]. Malaria was associated with a 1.5 times risk of anaemia though not statistically significant in the multivariate analysis (P = .19). Maternal parity <5 (P = .002), and stunting [(OR = 2.5, 95% CI = 1.3, 4.7), P = .004] were positively associated with anaemia. There was a positive correlation between household size and income (Pearson X 2 = 22.96; P = .001), implying that large families were of higher socioeconomic status.This study demonstrates that anaemia is more prevalent in the under-5 age. The risk factors are stunting and low maternal parity. Interventions that address nutritional deficiencies in both pre-school and school children are recommended. Malaria and helminthiasis control measures counter the risk of anaemia. Further studies are required to investigate the association between maternal parity and anaemia found in this study.

    Prevalence, Severity and Factors Associated with Dental Caries Among School Adolescents in Uganda: A Cross-Sectional Study
    (Brazilian dental journal, 2020) Ndagire, Barbara; Kutesa, Annet; Ssenyonga, Ronald; Kiiza, Harriet Mayanja; Nakanjako, Damalie; Rwenyonyi, Charles Mugisha
    Dental caries is one of the most prevalent diseases in developing countries. However, there is limited data on the prevalence and factors associated with dental caries in Ugandan adolescents. The purpose of the present study was to describe the prevalence, severity of dental caries and to determine the factors associated with the disease among school adolescents in Uganda. A cross sectional study was conducted at two secondary schools from Kampala (n=197) and Mukono (n=209) districts, Uganda. At both schools, random sampling was used to select the participating classes and the 406 adolescents (11-19 years) eligible to participate in the research. Dental caries was examined using the Decayed, Missing and Filled Teeth (DMFT) index, and a questionnaire was used to collect other relevant data in form of an oral interview. The data were analyzed using STATA version 12. The data was declared as survey data and all analyses were done with svy command. The prevalence of caries was determined as a percentage of individuals with DMFT score ≥1. Modified Poisson regression models were utilized to assess the association between prevalence, severity of dental caries and independent variables. The overall prevalence of dental caries was 66.0% and mean DMFT score of 2.18±2.67. Dental caries prevalence and severity were significantly (p<0.05) associated with tooth cleaning device, age and history of previous dental visit. There was a high prevalence and severity of dental caries among adolescents, which emphasizes the urgent need to develop and design appropriate interventions to reduce the disease burden.
