Assessing a novel point-of-care ultrasound training program for rural healthcare providers in Kenya

Background: A novel point-of-care ultrasound (PoCUS) training program was developed to train rural healthcare providers in Kenya on the Focused Assessment with Sonography for Trauma (FAST), thoracic ultrasound, basic echocardiography, and focused obstetric ultrasonography. The program includes a multimedia manual, pre-course testing, 1-day hands-on training, post-testing, 3-month post-course evaluation, and scheduled refresher training. This study evaluates the impact of the course on PoCUS knowledge and skills. Competency results were compared based on number of previous training/refresher sessions and time elapsed since prior training. Methods: Trainees were evaluated using a computer-based, 30 question, multiple-choice test, a standardized observed structured clinical exam (OSCE), and a survey on their ultrasound use over the previous 3 months. Results: Thirty-three trainees were evaluated at 21 different facilities. All trainees completed the written exam, and 32 completed the OSCE. Nine trainees out of 33 (27.3%) passed the written test. Trainees with two or more prior training sessions had statistically significant increases in their written test scores, while those with only one prior training session maintained their test scores. Time elapsed since last training was not associated with statistically significant differences in mean written test scores. Mean image quality scores (95% confidence interval) were 2.65 (2.37–2.93) for FAST, 2.41 (2.03–2.78) for thoracic, 2.22 (1.89–2.55) for cardiac, and 2.95 (2.67–3.24) for obstetric exams. There was a trend towards increased mean image quality scores with increases in the number of prior training sessions, and a trend towards decreased image quality with increased time elapsed since previous training. Forty percent of trainees reported performing more than 20 scans in the previous 3 months, while 22% reported less than 10 scans in the previous 3 months. Second and third trimester focused obstetric ultrasound was the most frequently performed scan type. Frequency of scanning was positively correlated with written test scores and image quality scores. Conclusion: This novel training program has the potential to improve PoCUS knowledge and skills amongst rural healthcare providers in Kenya. There is an ongoing need to increase refresher/re-training opportunities and to enhance frequency of scanning in order to improve PoCUS competency

Feasibility of project ECHO telementoring to build capacity among non-specialist emergency care providers

The COVID-19 pandemic has led to global disruptions in emergency medicine (EM) teaching and training and highlighted the need to strengthen virtual learning platforms. This disruption coincides with essential efforts to scale up training of the emergency healthcare workforce, particularly in low-resource settings where the specialty is not well developed. Thus, there is growing interest in strengthening virtual platforms that can be used to support emergency medicine educational initiatives globally. These platforms must be robust, context specific and sustainable in low-resource environments. This report describes the implementation of Project ECHO (Extension for Community Healthcare Outcomes), a telementoring platform originally designed to extend specialist support to health care workers in rural and underserved areas in New Mexico. This platform has now been implemented successfully across the globe. We describe the challenges and benefits of the Project ECHO model to support a Point-of-Care Ultrasound (POCUS) training program for health care providers in Kenya who do not have specialty training in emergency medicine. Our experience using this platform suggests it is amenable to capacity building for non-specialist emergency care providers in low-resource settings, but key challenges to implementation exist. These include unreliable and costly internet access and lack of institutional buy-in

International Scope of Emergency Ultrasound: Barriers in Applying Ultrasound to Guide Central Line Placement by Providers in Nairobi, Kenya

Background: While ultrasound (US) use for internal jugular central venous catheter (CVC) placement is standard of care in North America, most developing countries have not adopted this practice. Previous surveys of North American physicians have identified lack of training and equipment availability as the most important barriers to the use of US. Objective: We sought to identify perceived barriers to the use of US to guide CVC insertion in a resource-constrained environment. Methods: Prior to an US-guided CVC placement training course conducted at the Aga Khan University Hospital in Nairobi, Kenya, physicians were asked to complete a survey to determine previous experience and perceived barriers. Survey responses were analyzed using summary statistics and the Rank-Sum test based on different specialty, gender, and previous US experience. Results: There were 23 physicians who completed the course and the survey. 52% (95% CI: 0.30–0.73) had put in \u3e20 CVCs. 21.7% (95% CI: 0.08–0.44) of participants had previous US training, but none in the use of US for CVC insertion. The respondents expressed agreement with statements describing the ease of the use and improved success rate with US guidance. There was less agreement to statements describing the relative convenience and cost effectiveness of US CVC placement compared to the landmark technique. The main perceived barriers to utilization of US guidance included lack of training and limited availability of US equipment and sterile sheaths. Conclusion: Perceived barriers to US-guided CVC placement in our population closely mirrored those found among North American physicians, including lack of training and limited availability of US machines and equipment. These barriers have the potential to be addressed by targeted educational and administrative interventions

The status and future of emergency care in the Republic of Kenya

Kenya is a rapidly developing country with a growing economy and evolving health care system. In the decade since the last publication on the state of emergency care in Kenya, significant developments have occurred in the country\u27s approach to emergency care. Importantly, the country decentralized most health care functions to county governments in 2013. Despite the triple burden of traumatic, communicable, and non-communicable diseases, the structure of the health care system in the Republic of Kenya is evolving to adapt to the important role for the care of emergent medical conditions. This report provides a ten-year interval update on the current state of the development of emergency medical care and training in Kenya, and looks ahead towards areas for growth and development. Of particular focus is the role emergency care plays in Universal Health Coverage, and adapting to challenges from the devolution of health care

Building focused cardiac ultrasound capacity in a lower middle-income country: A single centre study to assess training impact

Background: In low- and middle-income countries (LMICs) where echocardiography experts are in short supply, training non-cardiologists to perform Focused Cardiac Ultrasound (FoCUS) could minimise diagnostic delays in time-critical emergencies. Despite advocacy for FoCUS training however, opportunities in LMICs are limited, and the impact of existing curricula uncertain. The aim of this study was to assess the impact of FoCUS training based on the Focus Assessed Transthoracic Echocardiography (FATE) curriculum. Our primary objective was to assess knowledge gain. Secondary objectives were to evaluate novice FoCUS image quality, assess inter-rater agreement between expert and novice FoCUS and identify barriers to the establishment of a FoCUS training programme locally. Methods: This was a pre-post quasi-experimental study at a tertiary hospital in Nairobi, Kenya. Twelve novices without prior echocardiography training underwent FATE training, and their knowledge and skills were assessed. Pre- and post-test scores were compared using the Wilcoxon signed-rank test to establish whether the median of the difference was different than zero. Inter-rater agreement between expert and novice scans was assessed, with a Cohen\u27s kappa \u3e0.6 indicative of good inter-rater agreement. Results: Knowledge gain was 37.7%, with a statistically significant difference between pre-and post-test scores (z = 2.934, p = 0.001). Specificity of novice FoCUS was higher than sensitivity, with substantial agreement between novice and expert scans for most FoCUS target conditions. Overall, 65.4% of novice images were of poor quality. Post-workshop supervised practice was limited due to scheduling difficulties. Conclusions: Although knowledge gain is high following a brief training in FoCUS, image quality is poor and sensitivity low without adequate supervised practice. Substantial agreement between novice and expert scans occurs even with insufficient practice when the prevalence of pathology is low. Supervised FoCUS practice is challenging to achieve in a real-world setting in LMICs, undermining the effectiveness of training initiatives

Appropriateness of clinical severity classification of new WHO childhood pneumonia guidance : a multi-hospital, retrospective, cohort study

Background: Management of pneumonia in many low-income and middle-income countries is based on WHO guidelines that classify children according to clinical signs that define thresholds of risk. We aimed to establish whether some children categorised as eligible for outpatient treatment might have a risk of death warranting their treatment in hospital. Methods: We did a retrospective cohort study of children aged 2–59 months admitted to one of 14 hospitals in Kenya with pneumonia between March 1, 2014, and Feb 29, 2016, before revised WHO pneumonia guidelines were adopted in the country. We modelled associations with inpatient mortality using logistic regression and calculated absolute risks of mortality for presenting clinical features among children who would, as part of revised WHO pneumonia guidelines, be eligible for outpatient treatment (non-severe pneumonia). Findings: We assessed 16 162 children who were admitted to hospital in this period. 832 (5%) of 16 031 children died. Among groups defined according to new WHO guidelines, 321 (3%) of 11 788 patients with non-severe pneumonia died compared with 488 (14%) of 3434 patients with severe pneumonia. Three characteristics were strongly associated with death of children retrospectively classified as having non-severe pneumonia: severe pallor (adjusted risk ratio 5·9, 95% CI 5·1–6·8), mild to moderate pallor (3·4, 3·0–3·8), and weight-for-age Z score (WAZ) less than −3 SD (3·8, 3·4–4·3). Additional factors that were independently associated with death were: WAZ less than −2 to −3 SD, age younger than 12 months, lower chest wall indrawing, respiratory rate of 70 breaths per min or more, female sex, admission to hospital in a malaria endemic region, moderate dehydration, and an axillary temperature of 39°C or more. Interpretation: In settings of high mortality, WAZ less than −3 SD or any degree of pallor among children with non-severe pneumonia was associated with a clinically important risk of death. Our data suggest that admission to hospital should not be denied to children with these signs and we urge clinicians to consider these risk factors in addition to WHO criteria in their decision making

Impact of point-of-care ultrasound use on patient referral decisions in rural Kenya: a mixed methods study

Abstract Background Point-of-care ultrasound (POCUS) is recognized as a key imaging modality to bridge the diagnostic imaging gap in Low- and Middle-Income Countries (LMICs). POCUS use has been shown to impact patient management decisions including referral for specialist care. This study explored the impact of POCUS use on referral decisions among trained healthcare providers working in primary rural and peri-urban health facilities in Kenya. Methods A concurrent mixed methods approach was used, including a locally developed survey (N = 38) and semi-structured interviews of POCUS trained healthcare providers (N = 12). Data from the survey was descriptively analyzed and interviews were evaluated through the framework matrix method. Results Survey results of in-facility access to Xray, Ultrasonography, CT scan and MRI were 49%, 33%, 3% and 0% respectively. Only 54% of the facilities where trainees worked had the capacity to perform cesarean sections, and 38% could perform general surgery. Through a combined inductive and deductive evaluation of interview data, we found that the emerging themes could be organized through the framework of the six domains of healthcare quality as described by the Institute of Medicine: Providers reported that POCUS use allowed them to make referral decisions which were timely, safe, effective, efficient, equitable and patient-centered. Challenges included machine breakdown, poor image quality, practice isolation, lack of institutional support and insufficient feedback on the condition of patients after referral. Conclusion This study highlighted that in the setting of limited imaging and surgical capacity, POCUS use by trained providers in Kenyan primary health facilities has the potential to improve the patient referral process and to promote key dimensions of healthcare quality. Therefore, there is a need to expand POCUS training programs and to develop context specific POCUS referral algorithms
