    Comparison of QSOFA and sirs scores for the prediction of adverse outcomes of secondary peritonitis among patients admitted on the adult surgical ward in a tertiary teaching hospital in Uganda: a prospective cohort study
    (BMC Emergency Medicine, 2021) Nkonge, Emmanuel; Kituuka, Olivia; Ocen, William; Ariaka, Herbert; Ogwal, Alfred; Ssekitoleko, Badru
    SIRS and qSOFA are two ancillary scoring tools that have been used globally, inside and outside of ICU to predict adverse outcomes of infections such as secondary peritonitis. A tertiary teaching hospital in Uganda uses SIRS outside the ICU to identify patients with secondary peritonitis, who are at risk of adverse outcomes. However, there are associated delays in decision making given SIRS partial reliance on laboratory parameters which are often not quickly available in a resource limited emergency setting. In response to the practical limitations of SIRS, the sepsis-3 task force recommends qSOFA as a better tool. However, its performance in patients with secondary peritonitis in comparison to that of SIRS has not been evaluated in a resource limited setting of a tertiary teaching hospital in a low and middle income country like Uganda. Objective: To compare the performance of qSOFA and SIRS scores in predicting adverse outcomes of secondary peritonitis among patients on the adult surgical wards in a tertiary teaching hospital in Uganda. Methods: This was a prospective cohort study of patients with clinically confirmed secondary peritonitis, from March 2018 to January 2019 at the Accident and Emergency unit and the adult surgical wards of a tertiary teaching hospital in Uganda. QSOFA and SIRS scores were generated for each patient, with a score of ≥2 recorded as high risk, while a score of < 2 recorded as low risk for the adverse outcome respectively. After surgery, patients were followed up until discharge or death. In-hospital mortality and prolonged hospital stay were the primary and secondary adverse outcomes, respectively. Sensitivity, specificity, PPV, NPV and accuracy at 95% confidence interval were calculated for each of the scores using STATA v.13. Results: A total of 153 patients were enrolled. Of these, 151(M: F, 2.4:1) completed follow up and were analysed, 2 were excluded. Mortality rate was 11.9%. Fourty (26.5%) patients had a prolonged hospital stay. QSOFA predicted in-hospital mortality with AUROC of 0.52 versus 0.62, for SIRS. Similarly, qSOFA predicted prolonged hospital stay with AUROC of 0.54 versus 0.57, for SIRS. Conclusion: SIRS is superior to qSOFA in predicting both mortality and prolonged hospital stay among patients with secondary peritonitis. However, overall, both scores showed a poor discrimination for both adverse outcomes and therefore not ideal tools.

    Hyperglycemia in severe traumatic brain injury patients and its association with thirty-day mortality: a prospective observational cohort study in Uganda
    (PeerJ, 2021) Matovu, Paul; Kirya, Musa; Galukande, Moses; Kiryabwire, Joel; Mukisa, John; Ocen, William; Wilson, Michael Lowery; Abio, Anne; Lule, Herman
    Traumatic brain injury (TBI) is a growing public health concern that can be complicated with an acute stress response. This response may be assessed by monitoring blood glucose levels but this is not routine in remote settings. There is a paucity of data on the prevalence of hyperglycemia and variables associated with mortality after severe TBI in Uganda. Objective: We aimed to determine the prevalence of hyperglycemia in patients with severe TBI and variables associated with 30-day mortality at Mulago National Referral Hospital in Uganda. Methods: We consecutively enrolled a cohort 99 patients patients with severe TBI. Serum glucose levels were measured at admission and after 24 h. Other study variables included: mechanism of injury, CT findings, location and size of hematoma, and socio-demographics. The main outcome was mortality after 30 days of management and this was compared in patients with hyperglycemia more than 11.1 mmol/L to those without. Results: Most patients (92.9%) were male aged 18–30 years (47%). Road Traffic Collisions were the most common cause of severe TBI (64.7%) followed by assault (17.1%) and falls (8.1%). Nearly one in six patients were admitted with hyperglycemia more than 11.1 mmol/L. The mortality rate in severe TBI patients with hyperglycemia was 68.8% (OR 1.47; 95% CI [0.236–9.153]; P = 0.063) against 43.7% in those without hyperglycemia. The presence of hypothermia (OR 10.17; 95% CI [1.574–65.669]; P = 0.015) and convulsions (OR 5.64; 95% CI [1.541–19.554]; P = 0.009) were significant predictors of mortality. Conclusion: Hypothermia and convulsions at admission were major predictors of mortality in severe TBI. Early hyperglycemia following severe TBI appears to occur with a tendency towards high mortality. These findings justify routine glucose monitoring and could form the basis for establishing a blood sugar control protocol for such patients in remote settings.

    Quality of Life of Adult Individuals with Intestinal Stomas in Uganda: a Cross Sectional Study
    (African health sciences, 2021) Ssewanyana, Yasin; Ssekitooleko, Badru; Suuna, Bashir; Bua, Emmanuel; Wadeya, Joseph; Makumbi, Timothy K.; Ocen, William; Omona, Kizito
    Intestinal stomas remain important life-saving surgical options in a wide range of gastrointestinal pathologies globally. Living with a stoma has potential to impair the patient’s quality of life, often with associated negative psychological effects. To evaluate the quality of life among intestinal stoma patients under Mulago National Referral Hospital (MNRH), with emphasis on psychological effects and effects on family-social interactions. A cross-sectional study carried out at surgical outpatient clinics of MNRH between January and June 2018. Data was collected using Stoma-QOL questionnaire, PHQ-9 and GAD-7 from 51 participants who had lived with intestinal stomas for at least a month. Of the 51 participants, male: female ratio was 4:1 and aged 18-84 years (mean age 44.04+18.47 years). 76.5% had colostomy; 23.5% had ileostomy. Majority (88.2%) had temporary stomas. The overall mean Stoma-QOL score was 55.12+ 17.04. Only about a quarter (24%) of participants had Stoma-QOL scores >70 (best). Most patients exhibited negative psy- chological effects (anxiety-100%, concerns about changed body image - 96.1% and depression - 88.4%). Most participants had low levels of stoma-related quality of life, suffered negative psychological effects and exhibited limited social interactions. This calls for efforts to support Stoma patients adapt beter life.
