Background

Nurses from the emergency department (ED) and the intensive care unit (ICU) must interact during the handover procedure. Factors such as unit boundaries, the interaction between different specialities, patient acuities, and treatment adjustments generate specific negotiating and teamwork problems during the transition of patients from ED to ICU.

Objective

This study aimed to describe the opinions of nurses regarding the effectiveness of handover practices between nurses in the ED and ICU in a major academic hospital in Gauteng province, South Africa.

Method

An analytical cross-sectional survey design was used. Data were collected using a 16-item handover evaluation tool. It comprises two sections (1) biographical details and (2) 16 statements about handover quality divided into five constructs, namely information transfer, shared understanding, working atmosphere, overall handover quality, and circumstances of handover. Data analysis was done utilising descriptive and non-parametric statistics.

Results

The majority (51.8%; n = 115) of the handovers occurred during the day. Out of 171 nurses, there were specialist practice emergency (19.2%; n = 33) and intensive care (28.0%; n = 48) nurses. There was statistical significance in information transfer between the ED and ICU nurses. (Me = 4.0, p < 0.05), compared to ICU nurses (Me = 3.0). Nurse specialist and non-specialist nurses' handovers differed statistically significantly on 12 of the 16 items on the rating scale, compared to 10 for non-specialist nurses' handovers.

Conclusion

The study showed that ED and ICU nurses have significantly different requirements and expectations for handover procedures. In addition to completed documentation, subtle interpretations of the information provided and received also impact the need. The ED and ICU nurses would need to agree on the contents of a structured handover framework because different specialities and departments have varied expectations to achieve an effective handover.

Background

A robust emergency care system is a cost-effective method of reducing preventable death and disability, especially in low-and middle-income countries. To scale emergency care expertise across the country, the Uganda Ministry of Health and Seed Global Health established the Emergency Medical Services (EMS) ECHO program. We describe the process of establishing the program in a resource-limited setting, best practices, and lessons learned in Uganda.

Methods

Investigators conducted a mixed-methods evaluation to assess the initial 4 months’ implementation of the EMS ECHO. We conducted pre/post-program assessments of healthcare worker knowledge, self-efficacy, and professional's satisfaction with the program. The analysis compared the differences between pre/post-test scores descriptively.

Results

The EMS ECHO was initiated in November 2021. A phased curriculum was developed with the initial phase focusing on the ABCDE (Airway, Breathing, Circulation, Disability, and Exposure) approach to the emergency patient. This phase reached 2,030 health workers cumulatively across 200 health facilities. The majority of the participants were medical doctors (n = 751, 37%), and nurses (n = 568, 28%). Majority of participants (95%) rated the sessions as informative. On whether the ECHO sessions diminished professional isolation, 66% agreed or strongly agreed.

Conclusions

Similar to other ECHO program evaluation results, Uganda's EMS ECHO program improved knowledge, skills, and the development of a virtual community of practice thereby diminishing professional isolation. It also demonstrates that through a planned stepwise process, virtual learning and telementorship can be used efficiently to improve healthcare worker knowledge,skills and multiply the limited number of emergency care experts available in the country.

Introduction

The performance of various weight estimation methods in children with sickle cell disease (SCD) and heart disease (HD) has not been studied. We aimed to determine and compare the accuracies of the Broselow, Mercy, PAWPER XL and PAWPER XL-MAC tapes in Ghanaian children with no known chronic diseases (controls), SCD and HD.

Methods

We prospectively recruited 631 children (199 with HD, 209 SCD and 223 controls) from the Komfo Anokye Teaching Hospital (KATH). Their weights were estimated using the Broselow, Mercy, PAWPER XL and PAWPER XL-MAC tapes. These estimated weights were compared to measured weight using mean percentage error (MPE), the proportion of weight estimates within ±10% (P10) and ±20% (P20) of measured weight. Bland-Altman limits of agreement (LOA) were determined to assess the precision of weight estimation and agreement with measured weight.

Results

The PAWPER XL, Mercy and PAWPER XL-MAC were the most accurate in all groups of children studied. All methods except the Broselow tape (BT), which performed best in the control group, had their best performance among children with SCD with negligible critical error rates (proportion of children with weight estimates > 20% of their actual weight). The P20 in the various groups of children using the BT were 88.36%, 80.21% and 51.10% respectively in the control, SCD and HD groups. The Mercy, PAWPER XL and PAWPER XL MAC tapes were generally above 90% in all groups.

Discussion

The Mercy, PAWPER XL and PAWPER XL-MAC tapes performed significantly better than the BT in all groups of children studied. These methods of weight estimation performed best in children with SCD with very little critical error.

Introduction

With the emergency medicine speciality in its nascency in Africa, EM doctoral programmes will need to be developed to facilitate the establishment of an evidence base that is responsive to the African populace. This study aimed to understand the thoughts, experiences, and opinions of current and past candidates of a South African EM PhD programme.

Methods

Descriptive, qualitative, semi-structured interviews were used to gather data on PhD EM candidates and graduates.

Findings

Four candidates, and four graduates were interviewed. Four categories emerged from the data 1) interviewees had various motivations for starting a PhD in EM, 2) candidate expectations and learning needs were not always aligned with reality, and the challenges and opportunities for success in the PhD programme are related both 3) intrinsically (candidate) and 4) extrinsically (system).

Discussion

Many of the barriers noted by the participants can be related to the nascency of the EM in Africa. Participants felt underprepared for their doctorate in terms of their baseline research literacy and skill. Candidates did not receive the level of student-supervisor engagement they desired. Candidates who are also clinicians faced both academic challenges and a resource-limited healthcare system. Pre-doctoral training may upskill prospective candidates in research literacy before they officially register. Distance-learning can be sub-optimal in terms of social interaction and collaboration. A well-curriculated, competency-based programme with clear outcomes, structured teaching-learning opportunities, intentional academic support throughout the programme, can mitigate the above. Protected academic time, promotion criteria which acknowledges academic contributions, financial incentives and more joint positions between universities and clinical services are potential solutions for clinician researcher challenges. An African PhD EM programme should produce graduates who are independent researchers, skilled in academic supervision and who are impactful to African needs when contributing to the African EM knowledge economy.

Simulation-based medical education is becoming a cornerstone in health education. Simulators are commonly expensive and not available in developing countries.

We propose a very low-cost simulator that any educator can realize. We describe here the steps to follow to develop this proposed simulator.

The emergency nursing role is incredibly challenging in Africa, and Botswana is no exception due to the lack of qualified nursing staff, the lack of specialty training, and the demanding work environment. Botswana's use of the primary healthcare system to provide treatment to all, including those in need of urgent care, demonstrates the necessity of integrating emergency care services into primary healthcare. Our objective with this manuscript is to demonstrate the value of emergency nursing as a specialty in Botswana.

Introduction

Intentional and accidental organophosphorus exposures pose a significant healthcare-related burden on South African communities. This study will review the demographics, characteristics and clinical course of patients presenting with features of acute organophosphorus toxicity to a regional Emergency Centre in Johannesburg, South Africa.

Methods

This was a retrospective chart review of all patients treated for possible acute organophosphorus toxicity from January 2020 to August 2021.

Results

A total of 205 patients were identified of which 134 patients were included in the study. The median age was 26 years with a male predominance (male= 56%, female=44%). 109 patients (81.3%) survived, 18 patients (13.4%) demised and the outcome of 7 patients (5.2%) was unknown. The median hospital length of stay was 8 days, (IQR= 5-13 days), and the longest hospital stay was 37 days in ICU. Atropinisation dose was significantly higher for intubated patients (median=140.0mg; IQR=90mg-219.5mg) compared to patients who were not intubated (median=60mg; IQR=20.5mg-120mg, p < 0.05). The length of stay was significantly higher for intubated patients (median=11 days; IQR=7-15 days) compared to patients who were not intubated (median=5 days; IQR=3-8 days, p < 0.00). There was a moderate positive correlation between atropinisation dose and length of stay (Correlation coefficient = 0.37, p < 0.00). There was a moderate negative correlation between atropinisation dose and cholinesterase level (Correlation coefficient= - 0.39, p < 0.00). Of those reported to have adverse effects 78.6%, were related to atropine toxicity.

Conclusion

Our study shows a high mortality rate secondary to organophosphorus toxicity. Significant exposures and thus higher doses of atropine were associated with increased length of stay and need for intubation. We found a high incidence of atropine-related adverse effects. More studies are needed to further establish the balance between the therapeutic and adverse effects of high-dose atropine as a treatment modality for organophosphorus toxicity.

Introduction

Chest imaging plays a prominent role in the assessment of patients with blunt trauma. Selection of the right approach at the right time is fundamental in the management of patients with blunt chest trauma^.[1] A reliable, economic, bedside, and rapidly accomplished screening test can be pivotal. [2]

Objective

The aim of this study was to compare the accuracy of extended- focused assessment with sonography for trauma (E-FAST) to that of the National Emergency X-Radiography Utilisation Study (NEXUS) chest algorithm in detecting blunt chest injuries.

Methods

This descriptive cross-sectional study included 50 polytrauma patients with blunt chest trauma from the emergency centre of Suez Canal University Hospital. E-FAST and computed tomography (CT) were conducted, followed by reporting of NEXUS criteria for all patients. Blinding of the E-FAST performer and CT reporter were confirmed. The results of both the NEXUS algorithm and E-FAST were compared with CT chest results.

Results

The NEXUS algorithm had 100% sensitivity and 15.3% specificity, and E-FAST had 70% sensitivity and 96.7% specificity, in the detection of pneumothorax.

In the detection of hemothorax, the sensitivity and specificity of the NEXUS algorithm were 90% and 7.5%, respectively, whereas E-FAST had a lower sensitivity of 80% and a higher specificity of 97.5%.

Conclusion

E-FAST is highly specific for the detection of hemothorax, pneumothorax, and chest injuries compared with the NEXUS chest algorithm, which demonstrated the lowest specificity. However, the NEXUS chest algorithm showed a higher sensitivity than E-FAST and hence can be used effectively to rule out thoracic injury.
