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.

Basic life support, a necessary inclusion in the medical curriculum: a cross-sectional survey of knowledge and attitude in Uganda.

BACKGROUND: Uganda continues to depend on a health system without a well-defined emergency response system. This is in the face of the rising cases of out-of-hospital cardiac arrest contributed largely to the high incidence of road traffic accidents. Non-communicable diseases are also on the rise further increasing the incidence of cardiac arrest. Medical students are key players in the bid to strengthen the health system which warrants an assessment of their knowledge and attitude towards BLS inclusion in their study curriculum. METHODS: A descriptive cross-sectional study was conducted in 2021 among undergraduate medical students across eight public and private universities in Uganda. An online-based questionnaire was developed using Google forms and distributed via identified WhatsApp groups. Chi-square or Fisher's exact test and logistic regression were performed in STATA 15 to assess the association between knowledge of BLS and demographics. P < 0.05 was considered statistically significant. RESULTS: Out of the total 354 entries obtained, 351 were analyzed after eligibility screening. Of these, (n = 250, 71.2%) were male less than 25 years (n = 273, 77.8%). Less than half (n = 150, 42.7%) participants had undergone formal BLS training. Less than a third of participants (n = 103, 29.3%) had good knowledge (≥ 50%) with an overall score of 42.3 ± 12.4%. Age (p = 0.045), level of academic progress (p = 0.001), and prior BLS training (p = 0.033) were associated with good knowledge. Participants with prior training were more likely to have more BLS knowledge (aOR: 1.7, 95% CI: 1.1-2.7, p = 0.009). The majority (n = 348, 99.1%) believed that BLS was necessary and would wish (n = 343, 97.7%) to have it included in their curriculum. CONCLUSIONS: Undergraduate medical students have poor BLS knowledge but understand its importance. Institutions need to adopt practical teaching methods such as clinical exposures, field experience in collaboration with local implementers, and participating in community health promotion campaigns.

Outcomes of management of intestinal obstruction at an urban tertiary hospital in sub Saharan Africa: a cross-sectional study.

BACKGROUND: Intestinal obstruction (IO) is a common cause of acute abdomen globally, it remains challenging as it increases surgical financial expenditure while also causing major morbidity. Clinically it presents with nausea, vomiting, colicky abdominal pain and cessation of bowel movements or passage flatus and stool. Diagnosis, especially in resource limited settings, can be clinical but is usually confirmed radiologically. We studied the current diagnosis, management and outcomes of IO in Mulago Hospital. MATERIALS AND METHODS: This was a prospective study done at all the surgical units of Mulago from January to May 2014 to assess general diagnosis and management of IO. Ethical approval was got in line with Helsinki declaration, we used pretested and validated questionnaires to collect data. Informed consent was got with eligible and consenting/assenting patients that fitted the inclusion criteria of age and presenting with suspected intestinal obstruction. Uni-variate and bi-variate variables analysis was done plus measures of association. RESULTS: We enrolled 135 patients, excluded 25 and recruited 110 patient. We had more males than females i.e. 71.8% males and 28.2% females. Colicky abdominal pain, abdominal distension, and vomiting were commonest symptoms, then abdominal distension, increased bowel sounds and abdominal tenderness were the commonest signs. Most patients' (51%) were diagnosed radiologically with a lesser number clinically diagnosed. "Dilated bowel loops" was the commonest radiological sign. Surgery was the main stay of management at 72.7% while 27.3% were conservatively managed. Postoperatively the bowels opened averagely on the 3rd post-operative day (POD) with return of bowel sounds occurring on 5th POD. Most discharges (73%) occurred by the 7th POD. Unfavourable outcomes were prolonged hospital stay followed by wound sepsis (surgical site infection) and then Mortality. CONCLUSION: This study noted that In Mulago we mostly diagnosed patients radiologically with most surgically managed and which is similar to regional practices. Postoperatively bowel opening happening on third POD with return of bowel sounds on fifth POD. Prolonged hospital stay followed by wound sepsis and then mortality were commonest unfavorable management outcomes.

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.

Comparison of Online and Classroom-based Formats for Teaching Emergency Medicine to Medical Students in Uganda.

OBJECTIVES: Severe global shortages in the health care workforce sector have made improving access to essential emergency care challenging. The paucity of trained specialists in low- and middle-income countries translates to large swathes of the population receiving inadequate care. Efforts to expand emergency medicine (EM) education are similarly impeded by a lack of available and appropriate teaching faculty. The development of comprehensive, online medical education courses offers a potentially economical, scalable, and lasting solution for universities experiencing professional shortages. METHODS: An EM course addressing core concepts and patient management was developed for medical students enrolled at Makerere University College of Health Sciences in Kampala, Uganda. Material was presented to students in two comparable formats: online video modules and traditional classroom-based lectures. Following completion of the course, students were assessed for knowledge gains. RESULTS: Forty-two and 48 students enrolled and completed all testing in the online and classroom courses, respectively. Student knowledge gains were equivalent (classroom 25 ± 8.7% vs. online 23 ± 6.5%, p = 0.18), regardless of the method of course delivery. CONCLUSIONS: A summative evaluation of Ugandan medical students demonstrated that online teaching modules are effectively equivalent and offer a viable alternative to traditional classroom-based lectures delivered by on-site, visiting faculty in their efficacy to teach expertise in EM. Web-based curriculum can help alleviate the burden on universities in developing nations struggling with a critical shortage of health care educators while simultaneously satisfying the growing community demand for access to emergency medical care. Future studies assessing the long-term retention of course material could gauge its incorporation into clinical practice.

Low dose ketamine versus morphine for acute severe vaso occlusive pain in children: a randomized controlled trial.

BACKGROUND AND AIMS: Acute pain episodes associated with sickle cell disease (SCD) are very difficult to manage effectively. Opioid tolerance and side effects have been major roadblocks in our ability to provide these patients with adequate pain relief. Ketamine is cheap, widely safe, readily available drug, with analgesic effects at sub-anesthetic doses and has been used in wide range of surgeries, pediatric burns dressing change and cancer related pain however, literature concerning its use in sickle cell crises is still limited in our setting. This study aimed to establish if 1 mg/kg of intravenous ketamine is non inferior to intravenous morphine 0.1 mg/kg in severe SCD-associated pain. METHODS: We performed an institutional review board-approved randomized, prospective, double-blinded, active-control, non-inferiority trial at the national referral sickle cell center. Children between 7 and 18 years of age with severe painful sickle cell crisis, defined by numerical rating scale score of greater or equal to 7 were enrolled. Patients were consented and randomized to receive, either IV ketamine (LDK) 1 mg/kg or IV morphine (MOR) 0.1 mg/kg as an infusion over 10 min. The primary endpoint is maximal change in Numerical Rating Scale (NRS) pain score. Secondary outcomes were, incidence of adverse effects, optimal time to and duration of action of ketamine and incidence of treatment failures by treatment group. A clinically meaningful difference in validated pain scores was defined as 1.3 units. Assuming both treatments are on average equal, a sample size of 240 patients (120 per group) provided 95% power to demonstrate that IV LDK is non-inferior to IV morphine with a 0.05 level of significance and a 10% non-inferiority margin. All analyses were based on a modified intention to treat. This trial was registered with clinicaltrials.gov NCT02434939. RESULTS: Two hundred and forty patients were enrolled (LDK120, MOR120). Demographic variables and baseline NRS scores (8.9 vs. 9.2) were similar. LDK was comparable to MOR in the maximum change in NRS scores, 66.4% vs. 61.3% (MD 5.5; 95% CI -2.2 to -13.2). Time to achieve maximum reduction in NRS pain scores was at 19.8 min for LDK and 34.1 min for MOR. The average duration of action for LDK was 60 min. MOR had more patients still at maximum effect at 120 min (45.8% vs. 37.5%; RR 1.2; 95% CI 0.9-1.7). LDK patients were 11.3 times more likely to develop side effects, though were transient, anticipated and non-life threatening (37.5% vs. 3.3%). MOR had significantly more treatment failures 40% vs. 28.3% (RR 0.7; 95% CI 0.5-1.03, p=0.07) Vital signs and sedation scores were similar in both groups. CONCLUSIONS: Intravenous LDK at 1 mg/kg provides comparable analgesic effectiveness as IV MOR in the acute treatment of severe painful sickle cell crisis in children in the day care sickle cell center. However, it is associated with a high incidence of several transient, non-life threatening mild side effects. IMPLICATIONS: Intravenous ketamine at 1 mg/kg can be a reliable alternative to morphine in the management of severe painful sickle cell crisis especially in a resource limited area where morphine is not readily available.

Evaluation of a point-of-care immunoassay test kit 'StrongStep' for cryptococcal antigen detection.

BACKGROUND: HIV-associated cryptococcal meningitis is the leading cause of adult meningitis in Sub-Saharan Africa, accounting for 15%-20% of AIDS-attributable mortality. The development of point-of-care assays has greatly improved the screening and diagnosis of cryptococcal disease. We evaluated a point-of-care immunoassay, StrongStep (Liming Bio, Nanjing, Jiangsu, China) lateral flow assay (LFA), for cryptococcal antigen (CrAg) detection in cerebrospinal fluid (CSF) and plasma. METHODS: We retrospectively tested 143 CSF and 77 plasma samples collected from HIV-seropositive individuals with suspected meningitis from 2012-2016 in Uganda. We prospectively tested 90 plasma samples collected from HIV-seropositive individuals with CD4 cell count <100 cells/µL from 2016-2017 as part of a cryptococcal antigenemia screening program. The StrongStep CrAg was tested against a composite reference standard of positive Immy CrAg LFA (Immy, Norman, OK, USA) or CSF culture with statistical comparison by McNemar's test. RESULTS: StrongStep CrAg had a 98% (54/55) sensitivity and 90% (101/112) specificity in plasma (P = 0.009, versus reference standard). In CSF, the StrongStep CrAg had 100% (101/101) sensitivity and 98% (41/42) specificity (P = 0.99). Adjusting for the cryptococcal antigenemia prevalence of 9% in Uganda and average cryptococcal meningitis prevalence of 37% in Sub-Saharan Africa, the positive predictive value of the StrongStep CrAg was 50% in plasma and 96% in CSF. CONCLUSIONS: We found the StrongStep CrAg LFA to be a sensitive assay, which unfortunately lacked specificity in plasma. In lower prevalence settings, a majority of positive results from blood would be expected to be false positives.

Effect of low-dose ketamine on post-operative serum IL-6 production among elective surgical patients: a randomized clinical trial.

BACKGROUND: Surgery and Anesthesia cause an excessive pro-inflammatory response. Mulago Hospital is faced with staff shortage making post-operative pain management difficult.Interleukin-6 (IL-6) drives inflammatory pain, endothelial cell dysfunction and fibrogenesis. Ketamine is cheap and, readily available. We hypothesized that its attenuation of serum IL-6 was a surrogate for clinical benefit. MATERIALS AND METHODS: Institutional Review Board's approval was sought and RCT was registered at clinical trials.gov (identifier number: NCT01339065). Consenting patients were randomized to receive pre-incision intravenous ketamine - 0.5mg/kg or 0.9% saline placebo in weighted dosing. Blood samples were collected and laboratory analyzed at baseline, post-operatively in PACU, 24 and 48 hours respectively. RESULTS: We recruited 39 patients of whom 18 were randomized to the ketamine arm and 21 in the placebo arm with follow up at 24 and 48 hours. Serum IL-6 and IL-1ß levels were analyzed using ELIZA assay of pre-coated micro wells. Ketamine suppressed serum IL-6 at PACU with reduced increase at 24 hours. There was no reaction in 98% of IL-1ß assayed. CONCLUSION: Low-dose ketamine attenuated early serum IL-6 levels due to surgical response with reduced 24 hour increase, but the difference was not statistically significant and we recommend more studies.

Analgesic Effects of Preincision Ketamine on Postspinal Caesarean Delivery in Uganda's Tertiary Hospital: A Randomized Clinical Trial.

Background. Good postoperative analgesic management improves maternal satisfaction and care of the neonate. Postoperative pain management is a challenge in Mulago Hospital, yet ketamine is accessible and has proven benefit. We determined ketamine's postoperative analgesic effects. Materials and Methods. We did an RCT among consenting parturients that were randomized to receive either intravenous ketamine (0.25 mg/kg) or placebo after spinal anesthetic. Pain was assessed every 30 mins up to 24 hours postoperatively using the numerical rating scale. The first complaint of pain requiring treatment was noted as "time to first breakthrough pain." Results. We screened 100 patients and recruited 88 that were randomized into two arms of 44 patients that received either ketamine or placebo. Ketamine group had 30-minute longer time to first breakthrough pain and lower 24-hour pain scores. Postoperative diclofenac consumption was lesser in the ketamine group compared to placebo and Kaplan-Meier graphs showed a higher probability of experiencing breakthrough pain earlier in the placebo group. Conclusion. Preincision intravenous ketamine (0.25 mg/kg) offered 30-minute prolongation to postoperative analgesia requirement with reduced 24-hour pain scores. We recommend larger studies to explore this benefit. This trial is registered with Pan African Clinical Trial Registry number PACTR201404000807178.

Prevalence, associated factors and treatment of post spinal shivering in a Sub-Saharan tertiary hospital: a prospective observational study.

BACKGROUND: Surgery and anaesthesia cause shivering due to thermal dysregulation as a compensatory mechanism and is worsened by vasodilatation from spinal anaesthesia that redistributes core body heat. Due to paucity of data Mulago Hospital's post spinal shivering burden is unknown yet it causes discomfort and morbidity. METHODS: Ethical approval was obtained to perform the study among consenting mothers due for elective caesarean section from March to May 2011. We recruited ASA class I & II parturients and excluded non-consenting or spinal contra-indication patients. A standard spinal anaesthetic of 2mls of 0.5 % bupivacaine was given, intraoperative vitals were recorded every 5 min and we monitored for perioperative shivering till PACU discharge. RESULTS: We recruited 270 patients with majority being emergency caesarean deliveries (90.74 %), mainly due to failed progress from cephalopelvic disproportion. We noted 8.15 % shivering occuring mostly at 20 min, with hypotension plus hypothermia as associated factors. Intravenous pethidine (Meperidine) 25 mg effectively treated shivering and we had drowsiness, nausea and vomiting as PACU side effects that resolved on discharge to the ward. CONCLUSION: Post spinal shivering had a prevalence of 8.15 %, commonly occurred at 20 min postoperatively with hypotension plus hypothermia as main associated factors and intravenous Pethidine controlled it.

Abnormal Admission Chest X-Ray and MEWS as ICU Outcome Predictors in a Sub-Saharan Tertiary Hospital: A Prospective Observational Study.

Background. Critical care in Uganda is a neglected speciality and deemed costly with limited funding/prioritization. We studied admission X-ray and MEWS as mortality predictors of ICU patients requiring mechanical ventilation. Materials and Methods. We did a cross-sectional study in Mulago Hospital ICU and 87 patients for mechanical ventilation were recruited with mortality as the outcome of interest. Chest X-ray results were the main independent variable and MEWS was also gotten for all patients. Results. We recruited 87 patients; most were males (60.92%), aged between 16 and 45 years (59.77%), and most admissions for mechanical ventilation were from the Trauma Unit (30.77%). Forty-one (47.13%) of the 87 patients died and of these 34 (53.13%) had an abnormal CXR with an insignificant IRR = 1.75 (0.90-3.38) (p = 0.062). Patients with MEWS ≥ 5 (p values = 0.018) and/or having an abnormal superior mediastinum (p values = 0.013) showed a positive association with mortality while having a MEWS ≥ 5 had an incidence risk ratio = 3.29 (1.00-12.02) (p = 0.018). MEWS was a good predictor of mortality (predictive value = 0.6739). Conclusion. Trauma (31%) caused most ICU admissions, having an abnormal admission chest X-rays positively associated with mortality and a high MEWS was also a good predictor of mortality.

Prevalence, outcomes and factors associated with adult in hospital cardiac arrests in a low-income country tertiary hospital: a prospective observational study.

BACKGROUND: Research on cardiac arrest and cardiopulmonary resuscitation (CPR) has considerably increased in recent decades, and international guidelines for resuscitation have been implemented and have undergone several changes. Very little is known about the prevalence and management of in-hospital cardiac arrest in low-resource settings. We therefore sought to determine the prevalence, outcomes and associated factors of adult inpatients with cardiac arrest at a tertiary referral hospital in a low-income country. METHODS: Upon obtaining institutional approval, we conducted a prospective observational period prevalence study over a 2-month period. We recruited adult inpatients with cardiac arrest in the intensive care unit and emergency wards of Mulago Hospital, Uganda during the study period. We reviewed all files and monitoring charts, and also any postmortem findings. Data were analyzed with Stata 12 and statistical significance was set at p < 0.05. RESULTS: There was a cardiac arrest in 2.3% (190) of 8,131 hospital admissions; 34.5% occurred in the intensive care unit, 4.4% in emergency operating theaters, and 3.0% in emergency wards. A majority (63.2%) was unwitnessed, and only 35 patients (18.4%) received CPR. There was return of spontaneous circulation (ROSC) in 14 (7.4%) cardiac arrest patients. Survival to 24 h occurred in three ROSC patients, which was only 1.6% of all cardiac arrest patients during the study period. Trauma was the most common primary diagnosis and HIV infection was the most common co-morbidity. CONCLUSION: Our hospital has a high prevalence of cardiac arrest, and low rates of CPR performance, ROSC, and 24-hour survival. Single provider CPR; abnormal temperatures as well as after hours/weekend CAs were associated with lower survival rates.
