    Undernourished children presenting to an urban emergency department of a tertiary hospital in Tanzania: a prospective descriptive study

    by Prosper J. Bashaka, Hendry R. Sawe, Victor Mwafongo, Juma A. Mfinanga, Michael S. Runyon, Brittany L. Murray

    Background: Childhood undernutrition causes significant morbidity and mortality in low- and middle-income countries (LMICs). In Tanzania, the in-hospital prevalence of undernutrition in children under five years of age is approximated to be 30% with a case fatality rate of 8.8%. In Tanzania, the burden of undernourished children under five years of age presenting to emergency departments (EDs) and their outcomes are unknown. This study describes the clinical profiles and outcomes of this population presenting to the emergency department of Muhimbili National Hospital (ED-MNH), a large, urban hospital in Dar es Salaam, Tanzania. Methods: This was a prospective descriptive study of children aged 1–59 months presenting to the ED-MNH over eight weeks in July and August 2016. Enrolment occurred through consecutive sampling. Children less than minus one standard deviation below World Health Organization mean values for Weight for Height/Length, Height for Age, or Weight for Age were recruited. Structured questionnaires were used to document primary outcomes of patient demographics and clinical presentations, and secondary outcomes of 24-h and 30-day mortality. Data was summarised using descriptive statistics and relative risks (RR). Results: A total of 449 children were screened, of whom 34.1% (n = 153) met criteria for undernutrition and 95.4% (n = 146) of those children were enrolled. The majority of these children, 56.2% (n = 82), were male and the median age was 19 months (IQR 10–31 months). They presented most frequently with fever 24.7% (n = 36) and cough 24.0% (n = 35). Only 6.7% (n = 9) were diagnosed with acute undernutrition by ED-MNH physicians. Mortality at 24 h and 30 days were 2.9% (n = 4) and 12.3% (n = 18) respectively. A decreased level of consciousness with Glasgow Coma Scale below fifteen on arrival to the ED and tachycardia from initial vital signs were found to be associated with a statistically significant increased risk of death in undernourished children, with mortality rates of 16.1% (n = 23), and 24.6% (n = 35), respectively. Conclusions: In an urban ED of a tertiary referral hospital in Tanzania, undernutrition remains under-recognized and is associated with a high rate of in-hospital mortality.

    Emergency medicine residency training in Africa: overview of curriculum

    by Hendry R. Sawe, Abena Akomeah, Juma A. Mfinanga, Michael S. Runyon, Erin Noste

    Emergency Medicine (EM) is a rapidly developing specialty in Africa with several emergency medicine residency-training programs (EMRPs) established across the continent over the past decade. Despite rapid proliferation of the specialty, little is known about emergency care curriculum structure and content. We provide an overview of Africa’s EMRPs. This was a descriptive cross-sectional survey conducted of EMRPs in Africa between January 2017 and December 2017. Data were prospectively collected using a structured survey that was developed and administered through online data capture software, REDCap (Version 7.2.2, Vanderbilt, Nashville, TN, USA). Survey questions focused on curriculum structure and design, including clinical rotations, didactics, research, and evaluation. Data are summarized with descriptive statistics. The survey was sent to the leadership of 15 EMRPs in 12 different African countries and 11 (73%) responded. Five (46%) of the responding programs were started by local non-EM trained faculty, two (18%) were started by international partners, and the remainder by a combination of local non-EM faculty and international partners. Overall, Seven (64%) of the countries offer a 4-year EMRP. In General, 40% of curriculums are influenced the contents developed by African Federation for Emergency Medicine. All programs offer resident led-didactics, with a median of 12 h (Interquartile range 9–6 h) per month. All EMRPs have a mandatory research requirement. All EMRPs offer clinical rotations in the ED, Paediatrics, and Obstetrics and Gynaecology, while only 2 programs offer rotations in radiology and neonatal intensive care units. Only 46% of EMRPs have in-ED clinical supervision by specialist. The EMRPs in Africa were started by non-EM trained local faculty alone or collaboration with international partners. The curriculum offers most exposure to ED, and less exposure in radiology and neonatal intensive care. Residents are highly involved in leading didactics and less than half of the programs have in-ED specialist supervision of patient care.

    Modified systemic inflammatory response syndrome and provider gestalt predicting adverse outcomes in children under 5 years presenting to an urban emergency department of a tertiary hospital in Tanzania

    by Meera R. Nariadhara, Hendry R. Sawe, Michael S. Runyon, Victor Mwafongo, Brittany L. Murray

    Modified systemic inflammatory response syndrome (mSIRS) criteria for the pediatric population together with the provider gestalt have the potential to predict clinical outcomes. However, this has not been studied in low-income countries. We investigated the ability of mSIRS and provider gestalt to predict mortality and morbidity among children presenting to the ED of a tertiary level hospital in Tanzania. This prospective observational study enrolled a convenience sample of children under 5 years old, presenting to the Emergency Medicine Department of Muhimbili National Hospital from September 2015 to April 2016. Trained researchers used a structured case report form to record patient demographics, clinical presentation, initial provider gestalt of severity of illness, and the mSIRS criteria. Primary outcomes were 24-h mortality and overall in-hospital mortality. Data was analyzed using simple descriptive statistics, Kruskal-Wallis, Mann-Whitney U, and chi-squared tests. We enrolled 1350 patients, median age 17 months (interquartile range 8–32 months), and 58% were male. Provider gestalt estimates of illness severity were recorded for all patients and 1030 (76.3%) had complete data for mSIRS categorization. Provider gestalt classified 97 (7.2%) patients as healthy, 546 (40.4%) as mildly ill, 457 (33.9%) as moderately ill, and 250 (18.5%) as severely ill. Of the patients, classifiable by mSIRS, 411/1030 (39.9%) had ≥ 2 mSIRS criteria. In predicting 24-h mortality, the ≥ 2 mSIRS and gestalt “severely ill” had sensitivities of 82% and 81%, respectively, and specificity of 61% and 84%, respectively. In predicting overall in-hospital mortality, the ≥ 2 mSIRS and gestalt “severely ill” had sensitivities of 66% and 70% with a specificity of 62% and 86% respectively. Both the mSIRS and provider gestalt were highly specific for predicting 24-h and overall in-hospital mortality in our patient population. The clinical utility of these assessment methods is limited by the low positive predictive value.

    The prevalence of alcohol and illicit drug use among injured patients presenting to the emergency department of a national hospital in Tanzania: a prospective cohort study

    by Müller M. Mundenga, Hendry R. Sawe, Michael S. Runyon, Victor G. Mwafongo, Juma A. Mfinanga, Brittany L. Murray

    Alcohol and illicit drugs have been found to be major contributing factors leading to severe injuries in a variety of settings. In Tanzania, the use of these substances among injured patients has not been studied. We investigated the prevalence of positive tests for alcohol and illicit drug use among injured patients presenting to the emergency medicine department (ED) of Muhimbili National Hospital (MNH). This was a prospective cohort study of a consecutive sample of patients > 18 years of age presenting to the ED-MNH with injury related complaints in October and November 2015. A structured data sheet was used to record demographic information, mechanism of injury, clinical presentation, alcohol and illicit drug test results, and ED disposition. Alcohol levels and illicit drug use were tested by breathalyser device or swab stick alcohol test and multidrug urine panel, respectively. Patients were followed up for 24 h and 30 days using medical chart reviews and phone calls. Descriptive statistics and relative risk were used to describe the results. We screened 1011 patients and we enrolled all 143 (14.1%) patients who met inclusion criteria. 123 (86.0%) were male, the median age was 30 years (IQR: 23–36 years). The most frequent mechanism of injury was road traffic accidents (84.6%). 67/143 (46.9%) patients tested positive for alcohol and 44/122 (36.1%) patients tested positive for drugs. 29 (26.1%) tested positive for alcohol and drugs. The most frequently detected illicit drug was marijuana in 30/122 (24.5%) injured patients. 23/53 (43.4%) patients with positive alcohol testing self-reported alcohol use. 3/25 patients with positive illicit drug tests who were able to provide self-reports, self-reported drug use. At 30-day followup, 43 (64.2%) injured patients who tested positive for alcohol had undergone major surgery, 6 (9.0%) had died, and 36 (53.7%) had not yet returned to their baseline. The prevalence of alcohol and illicit drugs is very high in patients presenting to the ED-MNH with injury. Further studies are needed to generalise the results in Tanzania. Public health initiatives to decrease drinking and/or illicit drug use and driving should be implemented.

    Impact of short basic emergency medicine training in introducing emergency medicine as a specialty in Sub-Saharan Africa: experience from Tanzania

    by Peter S. Mabula, Hendry R. Sawe, Victor Mwafongo, Juma A. Mfinanga, Michael S. Runyon, Brittany L. Murray

    Emergency medicine (EM) is a new specialty in Tanzania. Little is known about how to introduce EM to health care providers (HCPs) in hospitals without EM. We determined the impact of a 2-day EM training program on the understanding, perception, and choice of EM as a career amongst HCPs at hospitals in Tanzania without EM. This was a pre- and post-training interventional study including randomly selected HCPs from four tertiary hospitals in Tanzania without EM. Understanding, perception, and desirability of EM as a career were assessed before and after a 2-day university-accredited basic EM short-course training given by EM physicians. A paper-based Likert scale (out of 5) questionnaire was used, which were analyzed by T tests, Mann-Whitney, and Kruskal-Wallis tests. During the study period, 96 health care providers (100% capture) in the four tertiary hospitals participated in the study. The median age of participants was 34 years (IQR 28–43); 35 (36.0%) were males. Sixty (63%) were nurses, 26 (27%) doctors, and 3 (3%) were administrators. The four hospitals were equally represented. Median pre-training scores for all Likert questions were 3.49 (IQR 3.3–3.9); understanding 3.3 (IQR 3.0–3.7), perception 3.40 (IQR 3.1–3.7), and career decision-making 3.7 (IQR 3.3–4.0). Post-training scores improved with median scores of 4.6 (IQR 4.5–4.7) overall, 4.7 (IQR 4.0–4.7) for understanding, 4.6 (IQR 4.5–4.9) for perception, and 4.7 (IQR 4.3–4.8) for career decision-making (all p < 0.01). A 2-day training in basic EM care had a positive impact on understanding, perception, and career decisions regarding EM amongst Tanzania HCPs that work in hospitals without EM. Follow-up to assess long-term impact, and expansion of this program, is recommended to foster EM in countries where this is a new specialty.

    Assessment of cardiopulmonary resuscitation knowledge and skills among healthcare providers at an urban tertiary referral hospital in Tanzania

    by Winfrida T. Kaihula, Hendry R. Sawe, Michael S. Runyon, Brittany L. Murray

    Early and effective CPR increases both survival rate and post-arrest quality of life. In limited resource countries like Tanzania, there is scarce data describing the basic knowledge of CPR among Healthcare providers (HCP). This study aimed to determine the current level of knowledge on, and ability to perform, CPR among HCP at Muhimbili National Hospital (MNH). This was a descriptive cross sectional study of a random sample of 350 HCP from all cadres and departments at MNH from October 2015 to March 2016. Each participant completed a with 25 question multiple choice and fill-in-the-blank CPR test and a practical test using a CPR manikin where the participant was videotaped for 1–2 min. Two expert observers independently viewed the videos and rated participant performance on a structured data form. The primary outcome of interest was staff member overall performance on the written and practical CPR testing. We enrolled 350 HCPs from all 12 MNH clinical departments. The median participant age was 35 (IQR 29–43) years, 225 (64%) were female and 138 (39%) had clinical experience of less than 5 years. Only 57 (16%) and 88 (25%) scored above 50% in written and practical tests, respectively according to local minimum passing test score and 13(4%) and 30 (9%) scored above 75% in written and practical tests, respectively according to international minimum passing test score on CPR. The 233(67%) HCP who reported prior experience performing CPR on an adult patient scored higher on testing than those without; 40% (IQR 28–54) versus 26% (IQR 16–42) respectively, but both groups had median scores <50%. The level of CPR knowledge and skills displayed by all cadres and in all departments was poor despite the fact that most providers reported having performed CPR in the past. Since MNH is a tertiary referral hospital, it may reflect the performance of resuscitation status of other local health centers in Tanzania and other low-income countries to employ a formal system of training every HCP in CPR. Staff should be certified and assessed regularly to ensure retention of resuscitation knowledge and skills.

    The clinical presentation, utilization, and outcome of individuals with sickle cell anaemia presenting to urban emergency department of a tertiary hospital in Tanzania

    by Hendry R. Sawe, Teri A. Reynolds, Juma A. Mfinanga, Michael S. Runyon, Brittany L. Murray, Lee A. Wallis, Julie Makani

    Sickle cell anaemia (SCA) is prevalent in sub-Saharan Africa, with high risk of complications requiring emergency care. There is limited information about presentation of patients with SCA to hospitals for emergency care. We describe the clinical presentation, resource utilization, and outcomes of SCA patients presenting to the emergency department (ED) at Muhimbili National Hospital (MNH) in Dar es Salaam, Tanzania. This was a prospective cohort study of consecutive patients with SCA presenting to ED between December 2014 and July 2015. Informed consent was obtained from all patients or patients’ proxies prior to being enrolled in the study. A standardized case report form was used to record study information, including demographics, relevant clinical characteristics and overall patients outcomes. Categorical variables were compared with chi-square test or Fisher’s exact test; continuous variables were compared with two-sample t-test or Mann-Whitney U-test. We enrolled 752 (2.7%) people with SCA from 28,322 patients who presented to the MNH-ED. The median age was 14 years (Interquartile range [IQR]: 6–23 years), and 395 (52.8%) were female. Pain 614 (81.6%), fever 289 (38.4%) were the most frequent presenting complaint. Patients with fever, hypoxia, altered mental status and bradycardia had statistically significant relative risk of mortality of 10.4, 153, 50 and 12.1 (p < 0.0001) respectively, compared to patients with normal vitals. Overall, 656 (87.2%) patients received Complete Blood Cell counts test, of these 342 (52.1%) had severe anaemia (haemoglobin < 7 g/dl), and a 30.3 (p = 0.02) relative risk of relative risk of mortality compare to patients with higher haemoglobin. Patients who had malaria, elevated renal function test and hypoglycemia, had relative risk of mortality of 22.9, 10.4 and 45.2 (p < 0.0001) respectively, compared to patient with normal values. Most 534 (71.0%) patients were hospitalized for in patients care, and the overall morality rate was 16 (2.1%). We described the clinical presentation, management, and outcomes of patients with SCA presenting to the largest public ED in Tanzania, as well as information on resource utilization. This information can inform development of treatment guidelines, clinical staff education, and clinical research aimed at optimizing care for SCA patients.

    Profile of patients with hypertensive urgency and emergency presenting to an urban emergency department of a tertiary referral hospital in Tanzania

    by Patrick J. Shao, Hendry R. Sawe, Brittany L. Murray, Juma A. Mfinanga, Victor Mwafongo, Michael S. Runyon

    Hypertensive crises are clinical syndromes grouped as hypertensive urgency and emergency, which occur as complications of untreated or inadequately treated hypertension. Emergency departments across the world are the first points of contact for these patients. There is a paucity of data on patients in hypertensive crises presenting to emergency departments in Tanzania. We aimed to describe the profile and outcome of patients with hypertensive crisis presenting to the Emergency Department of Muhimbili National Hospital in Tanzania. This was a descriptive cohort study of adult patients aged 18 years and above presenting to the emergency department with hypertensive urgency or emergency over a four-month period. Trained researchers used a structured data sheet to document demographic information, clinical presentation, management and outcome. Descriptive statistics with 95% confidence intervals (CIs) are presented as well as comparisons between the groups with hypertensive urgency vs. emergency. We screened 8002 patients and enrolled 203 (2.5%). The median age was 55 (interquartile range 45–67 years) and 51.7% were females. Overall 138 (68%) had hypertensive emergency; and 65 (32%) had hypertensive urgency, for an overall rate of 1.7% (95% CI: 1.5 to 2.0%) and 0.81% (95% CI: 0.63 to 1.0%), respectively. Altered mental status was the most common presenting symptom in hypertensive emergency [74 (53.6%)]; low Glasgow Coma Scale was the most common physical finding [61 (44.2%)]; and cerebrovascular accident was the most common final diagnosis [63 (31%)]. One hundred twelve patients with hypertensive emergency (81.2%) were admitted and three died in the emergency department, while 24 patients with hypertensive urgency (36.9%) were admitted and none died in the emergency department. In-hospital mortality rates for hypertensive emergency and urgency were 37 (26.8%) and 2 (3.1%), respectively. In our cohort of adult patients with elevated blood pressure, hypertensive crisis was associated with substantial morbidity and mortality, with the most vulnerable being those with hypertensive emergency. Further research is required to determine the aetiology, pathophysiology and the most appropriate strategies for prevention and management of hypertensive crisis.

    Patients with acute poisoning presenting to an urban emergency department of a tertiary hospital in Tanzania

    by Ghaniya S. Mbarouk, Hendry R. Sawe, Juma A. Mfinanga, John Stein, Shankar Levin, Victor Mwafongo, Michael S. Runyon, Teri A. Reynolds, Kent R. Olson

    Poisoning is a major public health concern in sub-Saharan Africa, affecting patients of all age groups. Poisoned patients often present to the emergency department (ED) and prompt evaluation and appropriate management are imperative to ensure optimal outcomes. Unfortunately, little is known about the specific presentations of poisoned patients in East Africa. We describe the clinical and epidemiological features of patients presenting to the Muhimbili National Hospital (MNH) ED with suspected toxicological syndromes. This prospective study enrolled a consecutive sample of ED patients who presented with a suspected toxicological syndrome from March 2013 to June 2013. Trained investigators completed a structured case report form (CRF) for each eligible patient, documenting the suspected poison, demographic information, the clinical presentation, and the ED outcome and disposition. The study data were analyzed and summarized with descriptive statistics. Of 8827 patients, who presented to ED-MNH, 106 (1.2%) met inclusion criteria, and all were enrolled. Among those enrolled, the median age was 28 years (interquartile range [IQR] 16 years), and 81 (76.4%) were male. Overall 55 (52%) were single, and 28 (26.4%) had professional jobs. 60 (56.6%) patients were referred from district hospitals, 86.8% of which were in Dar es Salaam. Only 13 (12.3%) of patients presented to the ED within 2 h of the toxic exposure. The etiology of poisoning included alcohol in 42 (50%), a mixture of different medications in 12 (14.3%), and snakebite in 6 (11.3%). Most exposures were intentional (63 [59.4%]) and were via the oral route (88 [83%]). The most common abnormal physical findings were altered mental status (66 [62.3%]) and tachypnoea (68 [64.2%]). One patient died in the ED and 98 (92.5%) required hospital admission. Most patients presenting to the ED with a toxicological syndrome were adult males with intentional exposures. The most common toxic exposure was alcohol (ethanol) intoxication and the most common abnormal findings were altered mental status and tachypnoea. More than three-quarter of patients presented after 2 h of exposure. Almost all patients were admitted to the hospital.
