Feasibility and acceptability of undertaking postmortem studies for tuberculosis medical research in a low income country.

Introduction: If we are to break new ground in difficult-to-treat or difficult-to-vaccinate diseases (such as HIV, malaria, or tuberculosis), we must have a better understanding of the immune system at the site of infection in humans. For tuberculosis (TB), the initial site of infection is the lungs, but obtaining lung tissues from subjects suffering from TB has been limited to bronchoalveolar lavage (BAL) or sputum sampling, or surgical resection of diseased lung tissue. Methods: We examined the feasibility of undertaking a postmortem study for human tuberculosis research at Mulago National Referral Hospital in Kampala, Uganda. Results: Postmortem studies give us an opportunity to compare TB-involved and -uninvolved sites, for both diseased and non-diseased individuals. We report good acceptability of the next-of-kin to consent for their relative's tissue to be used for medical research; that postmortem and tissue processing can be undertaken within 8 hours following death; and that immune cells remain viable and functional up to 14 hours after death. Discussion: Postmortem procedures remain a valuable and essential tool both to establish cause of death, and to advance our medical and scientific understanding of infectious diseases.

Trauma unit admissions at the Ugandan National Referral Hospital: a descriptive study.

Background: Injuries are a neglected epidemic globally accounting for 9% global deaths; 1.7 times that of HIV, TB and malaria combined. Trauma remains overlooked with key research and data focusing on infectious diseases yet Uganda has one of the highest rates of traumatic injury. We described demographics of patients admitted to Mulago Hospital's Shock Trauma Unit within the Emergency Department. Methods: This was a retrospective record review Trauma Unit admissions from July 2012 to December 2015. Information collected included: age, sex, time of admission, indication for admission and mechanism of trauma. Results: 834 patient records were reviewed. The predominant age group was 18-35 with majority of patients being male. 54% of patients presented during daytime with 46% admitted in the evening hours or overnight. Mechanism of injury was documented in 484 cases. The most common mechanism was Road Traffic Accident (67.4%), followed by assault (12.8%) and mob violence (5.6%). The most common indication for admission was traumatic brain injury (84.5%), followed by haemodynamic instability (20.0%) and blunt chest injury (6.1%). Conclusion: There's a significant burden of high-acuity injury particularly among males with RTAs as the leading cause of admission associated with Traumatic Brain Injury as main admission indication.

Trauma unit management and outcomes at an urban tertiary hospital in sub-Saharan Africa: a descriptive study.

Background: Injuries are a neglected burden despite accounting for 9% of deaths worldwide which is 1.7 times that of hiv, tb and malaria combined. Trauma remains overlooked as research and resources are focused on infectious diseases. Uganda with limited trauma epidemiological data has one of the highest traumatic injury rates. This study describes demographics, management and outcomes of patients admitted to mulago hospital trauma unit. Materials and methods: This study was a retrospective record review from july 2012 to december 2015. A data collected included age, time and vitals of admission plus interventions, management and outcomes after which it was analyzed. Results: 834 patient records were reviewed. The predominant age group was 18-35 and 86% of the patients were male. 54% of the patients presented during day and majority of the admission had gcs of less than 8. Antibiotics were given to 467 patients with mechanical ventilation (301) and intubation (289) as the frequent interventions done. 52% of admitted patients were discharged and 40% died. Conclusion: Most admissions' were of youthful age and had severe head injuries (gcs<8). 56% received antibiotics with frequent interventions beig mechanical ventilation and intubation. 52% of admitted patients were discharged and 40% died.

Impact of nursing education and a monitoring tool on outcomes in traumatic brain injury.

INTRODUCTION: Throughout the world, traumatic brain injury (TBI) is one of the leading causes of morbidity and mortality. Low-and middle-income countries experience an especially high burden of TBI. While guidelines for TBI management exist in high income countries, little is known about the optimal management of TBI in low resource settings. Prevention of secondary injuries is feasible in these settings and has potential to improve mortality. METHODS: A pragmatic quasi-experimental study was conducted in the emergency centre (EC) of Mulago National Referral Hospital to evaluate the impact of TBI nursing education and use of a monitoring tool on mortality. Over 24 months, data was collected on 541 patients with moderate (GCS9-13) to severe (GCS≤8) TBI. The primary outcome was in-hospital mortality and secondary outcomes included time to imaging, time to surgical intervention, time to advanced airway, length of stay and number of vital signs recorded. RESULTS: Data were collected on 286 patients before the intervention and 255 after. Unadjusted mortality was higher in the post-intervention group but appeared to be related to severity of TBI, not the intervention itself. Apart from number of vital signs, secondary outcomes did not differ significantly between groups. In the post-intervention group, vital signs were recorded an average of 2.85 times compared to 0.49 in the pre-intervention group (95% CI 2.08-2.62, p ≤ 0.001). The median time interval between vital signs in the post-intervention group was 4.5 h (IQR 2.1-10.6). CONCLUSION: Monitoring of vital signs in the EC improved with nursing education and use of a monitoring tool, however, there was no detectable impact on mortality. The high mortality among patients with TBI underscores the need for treatment strategies that can be implemented in low resource settings. Promising approaches include improved monitoring, organized trauma systems and protocols with an emphasis on early aggressive care and primary prevention.

A qualitative study exploring nurses' attitudes, confidence, and perceived barriers to implementing a traumatic brain injury nursing chart in Uganda.

INTRODUCTION: In Africa, traumatic brain injuries frequently result from road traffic injuries and assaults. Despite limited resources and the high costs of life-saving neurosurgical interventions, secondary brain injury prevention has the potential for improving outcomes. However, nurses and other medical personnel infrequently monitor vital signs, blood sugar, and pulse oximetry and only sporadically re-assess neurological status. METHODS: In one-on-one, semi-structured interviews, 27 nurses from Mulago Hospital's emergency centre, a tertiary care trauma hospital in Kampala, Uganda, provided feedback regarding a traumatic brain injury-focused education session and use of a nursing chart for detecting secondary brain injury. The interviews explored the nurses' confidence and perceived barriers to long-term chart implementation and traumatic brain injury care, as well as their ideas for improving this intervention. Interviews were audio recorded, transcribed, and coded using ATLAS.ti: Qualitative Data Analysis and Research Software (Cleverbridge, Inc., Chicago, USA) and Microsoft Word and Excel (Microsoft Office, Redmond, USA) for thematic content analysis. RESULTS: Key findings identified in the interviews included the nurses' attitudes toward the chart and their feelings of increased confidence in assessing and caring for these patients. The main barriers to continuous implementation included inadequate staffing and resources. CONCLUSION: Nurses were receptive to the education session and nursing chart, and felt that it increased their confidence and improved their ability to care for traumatic brain injured patients. However, lack of supplies, overwhelming numbers of patients, and inadequate staffing interfered with consistent monitoring of patients. The nurses offered various suggestions for improving traumatic brain injury care that should be further investigated. More research is needed to assess the applicability of a standardised traumatic brain injury nursing education and chart in a broader context.
