Evaluation of a digitally enhanced cardiac auscultation learning method in Cameroon: results of a controlled study.

BACKGROUND: Cardiac auscultation is an efficient and effective diagnostic tool, especially in low-income countries where access to modern diagnostic methods remains difficult. This study aimed to evaluate the effect of a digitally enhanced cardiac auscultation learning method on medical students' performance and satisfaction. METHODS: We conducted a double-arm parallel controlled trial, including newly admitted 4th -year medical students enrolled in two medical schools in Yaoundé, Cameroon and allocated into two groups: the intervention group (benefiting from theoretical lessons, clinical internship and the listening sessions of audio recordings of heart sounds) and the control group (benefiting from theoretical lessons and clinical internship). All the participants were subjected to a pretest before the beginning of the training, evaluating theoretical knowledge and recognition of cardiac sounds, and a post-test at the eighth week of clinical training associated with the evaluation of satisfaction. The endpoints were the progression of knowledge score, skills score, total (knowledge and skills) score and participant satisfaction. RESULTS: Forty-nine participants (27 in the intervention group and 22 in the control group) completed the study. The knowledge progression (+ 26.7 versus + 7.5; p ˂0.01) and the total progression (+ 22.5 versus + 14.6; p ˂ 0.01) were higher in the intervention group with a statistically significant difference compared to the control group. There was no significant difference between the two groups regarding skills progression (+ 25 versus + 17.5; p = 0.27). Satisfaction was higher in general in the intervention group (p ˂ 0.01), which recommended this method compared to the control group. CONCLUSION: The learning method of cardiac auscultation reinforced by the listening sessions of audio recordings of heart sounds improves medical students' performances (knowledge and global - knowledge and skills) who find it satisfactory and recommendable. TRIAL REGISTRATION: This trial has been registered the 29/11/2019 in the Pan African Clinical Trials Registry ( http://www.pactr.org ) under unique identification number PACTR202001504666847 and the protocol has been published in BMC Medical Education.

The Feasibility and Acceptability of Using Mobile Applications for HIV Testing, Prevention, and Treatment Among Adolescent Girls and Young Women in Cameroon: A Cross-Sectional Study.

ABSTRACT: Adolescent girls and young women (AGYW) are vulnerable populations to HIV/AIDS. We conducted a cross-sectional survey among 637 AGYW in Cameroon to study the feasibility and willingness to use mobile applications (apps) for HIV testing, prevention, and treatment. We found that phone ownership is high among AGYW, where 93.9% ( n = 598) of them (median age: 22 years, interquartile range: 21-24 years) had access to a smartphone, 49.5% ( n = 315) frequently searched for health information, and 48.9% ( n = 312) frequently used health-related apps. AGYW's willingness to use mobile apps for HIV testing, prevention, and treatment were 87.9% ( n = 560), 84.4% ( n = 538), and 84.9% ( n = 541), respectively. The high willingness to use apps was associated with older age, HIV testing, and searching for health information on a phone. Barriers to willingness included having no internet access, concerns about internet cost and privacy, and lack of consistent access to a smartphone.

Implementing Clinical Information Systems in Sub-Saharan Africa: Report and Lessons Learned From the MatLook Project in Cameroon.

BACKGROUND: Yaoundé Central Hospital (YCH), located in the capital of Cameroon, is one of the leading referral hospitals in Cameroon. The hospital has several departments, including the Department of Gynecology-Obstetrics (hereinafter referred to as "the Maternity"). This clinical department has faced numerous problems with clinical information management, including the lack of high-quality and reliable clinical information, lack of access to this information, and poor use of this information. OBJECTIVE: We aim to improve the management of clinical information generated at the Maternity at YCH and to describe the challenges, success factors, and lessons learned during its implementation and use. METHODS: Based on an open-source hospital information system (HIS), this intervention implemented a clinical information system (CIS) at the Maternity at YCH and was carried out using the HERMES model-the first part aimed to cover outpatient consultations, billing, and cash management of the Maternity. Geneva University Hospitals supported this project, and several outcomes were measured at the end. The following outcomes were assessed: project management, technical and organizational aspects, leadership, change management, user training, and system use. IMPLEMENTATION (RESULTS): The first part of the project was completed, and the CIS was deployed in the Maternity at YCH. The main technical activities were adapting the open-source HIS to manage outpatient consultations and develop integrated billing and cash management software. In addition to technical aspects, we implemented several other activities. They consisted of the implementation of appropriate project governance or management, improvement of the organizational processes at the Maternity, promotion of the local digital health leadership and performance of change management, and implementation of the training and support of users. Despite barriers encountered during the project, the 6-month evaluation showed that the CIS was effectively used during the first 6 months. CONCLUSIONS: Implementation of the HIS or CIS is feasible in a resource-limited setting such as Cameroon. The CIS was implemented based on good practices at the Maternity at YCH. This project had successes but also many challenges. Beyond project management and technical and financial aspects, the other main problems of implementing health information systems or HISs in Africa lie in digital health leadership, governance, and change management. This digital health leadership, governance, and change management should prioritize data as a tool for improving productivity and managing health institutions, and promote a data culture among health professionals to support a change in mindset and the acquisition of information management skills. Moreover, in countries with a highly centralized political system like ours, a high-level strategic and political anchor for such projects is often necessary to guarantee their success.

iCHECK-DH: Guidelines and Checklist for the Reporting on Digital Health Implementations.

BACKGROUND: Implementation of digital health technologies has grown rapidly, but many remain limited to pilot studies due to challenges, such as a lack of evidence or barriers to implementation. Overcoming these challenges requires learning from previous implementations and systematically documenting implementation processes to better understand the real-world impact of a technology and identify effective strategies for future implementation. OBJECTIVE: A group of global experts, facilitated by the Geneva Digital Health Hub, developed the Guidelines and Checklist for the Reporting on Digital Health Implementations (iCHECK-DH, pronounced "I checked") to improve the completeness of reporting on digital health implementations. METHODS: A guideline development group was convened to define key considerations and criteria for reporting on digital health implementations. To ensure the practicality and effectiveness of the checklist, it was pilot-tested by applying it to several real-world digital health implementations, and adjustments were made based on the feedback received. The guiding principle for the development of iCHECK-DH was to identify the minimum set of information needed to comprehensively define a digital health implementation, to support the identification of key factors for success and failure, and to enable others to replicate it in different settings. RESULTS: The result was a 20-item checklist with detailed explanations and examples in this paper. The authors anticipate that widespread adoption will standardize the quality of reporting and, indirectly, improve implementation standards and best practices. CONCLUSIONS: Guidelines for reporting on digital health implementations are important to ensure the accuracy, completeness, and consistency of reported information. This allows for meaningful comparison and evaluation of results, transparency, and accountability and informs stakeholder decision-making. i-CHECK-DH facilitates standardization of the way information is collected and reported, improving systematic documentation and knowledge transfer that can lead to the development of more effective digital health interventions and better health outcomes.

An Ontology-Based Semantic Model for Sharing and Reusability of Clinical Pathways Across Context (ShaRE-CP).

Clinical pathways (CP) enable a standardized and an efficient management of patients with common pathologies. As operational tools, they take into account knowledge from guidelines and from the context (e.g. availability of resources) in which different interventions are to be carried out. Mastering the coherence of interactions between all these knowledge domains is a major challenge for the implementation of CP. This scientific work led to the development of an ontology called Shareable and Reusable Clinical Pathway Ontology (ShaRE-CP) which integrates four knowledge domains (CP, guidelines, health resources and context) and to the establishment of existing semantic links between them. The consistency of this semantic model has been validated by using reasoners. This ontology can serve as a basis for the development of a decision support system for planning and managing patient care.

Evaluation of the Efficiency of Telemedicine in the Management of Cardiovascular Diseases in Primary Healthcare in Sub-Saharan Africa: A Medico-Economic Study in Cameroon.

OBJECTIVE: To assess the efficiency of tele-expertise (tele-ECG) for patients and for health facilities in managing patients with cardiovascular diseases (CVDs) in primary health care in Cameroon. METHOD: This study was a medico-economic study combining two approaches: cost minimization and cost-effectiveness analysis. It was conducted alongside the previous published controlled multicenter study carried out in Cameroon's two health facilities where tele-ECG has been implemented (intervention centres) and two other where telemedicine has been not implemented (control centres). RESULTS: The average total cost for patients was 9 286 F CFA (US$: 16) in the intervention centres compared to 28 357 F CFA (US$: 49) in the control centres (p <0.01). The calculated ICER favouring tele-ECG was 25 459.6 F CFA (US$: 44). DISCUSSION: Telemedicine is efficient for managing patients with CVDs in primary health care in Cameroon. It enables health facilities in remote areas to offer new healthcare services at a lower cost and improve patients' financial access to healthcare.

Evaluation of a digitally enhanced cardiac auscultation learning method: a controlled study.

BACKGROUND: Cardiac auscultation remains an efficient and accessible diagnostic tool, especially in resource-limited countries where modern diagnostic devices like cardiac ultrasound are expensive and difficult to access. However, cardiac auscultation skills of medical students and physicians are declining, mainly because of an ineffective teaching method for this technique. The objective of this study is to evaluate the effect of a digitally enhanced cardiac auscultation learning method on participants' theoretical knowledge and auscultation skills. METHODS: This will be a controlled study with two parallel arms (1:1). Participants (fourth-year medical students) will be divided into two groups: an intervention group (receiving additional lectures, clinical internship and audio listening sessions) and a control group (receiving additional lectures and clinical internship). At the beginning of the study, all participants will undergo a pre-test that consist of two parts: a knowledge assessment based on multiple-choice questions and a skills assessment based on recognition of cardiac sounds from audio files. Thereafter, three specific additional lectures on cardiac auscultation will be delivered and all participants will take part in their official clinical internship. During these clinical internships (eight weeks), participants of the intervention group will be invited to two listening sessions based on five digital recordings of heart sounds. At the end of the clinical internship, all participants will be invited to a post-test to evaluate their knowledge, skills and satisfaction according to their learning method. The main outcome will be the participants' knowledge progression. The other outcomes will be the participants' skills progression, participants' total progression and satisfaction. Data will be collected and analyzed in per protocol. DISCUSSION: This study could contribute to the development of a learning method that takes into account the advantages of the conventional method and the contribution of digital technology. Positive results could lead to improved cardiac auscultation skills among health professionals, especially in developing countries. TRIAL REGISTRATION: The trial is registered on the Pan-African Clinical Trials Registry ( http://www.pactr.org ) under unique identification number: PACTR202001504666847 , registered the 29 November 2019.

Evaluation of the Effectiveness of Telemedicine in the Management of Cardiovascular Diseases in Primary Health Care in Cameroon: An Interventional Study.

OBJECTIVE: This study aimed to evaluate the effectiveness of tele-expertise (tele-ECG) in primary health care in Cameroon for the management of patients with cardiovascular diseases or risk factors. METHOD: It is a controlled multicenter study carried out in Cameroon's two health facilities where tele-ECG has been implemented (intervention centers) and two other where telemedicine has been not implemented (control centers). Patients having cardiovascular risk factors or diseases received usual primary health care in the control centers. In contrast, they received usual primary health care and could perform an ECG associated with cardiologists' remote expertise (tele-ECG) in the intervention centers. The primary outcome was to evaluate the rate of patients' access to an ECG test and to cardiologist' expertise. RESULTS AND DISCUSSION: Telemedicine is effective for the management of patients with cardiovascular diseases in primary health care. It could improve healthcare providers' clinical processes, clinical outcomes of patients and their satisfaction.

Learning From eHealth Implementations Through "Implementomics": A Multidimensional Annotation Model Applied to eHealth Projects of the RAFT Network.

The implementation of digital health technologies has increased globally, producing substantial amounts of information and knowledge. While there are still areas in digital health that are understudied, concurrently there is an exponential increase in published articles, guidelines, methods, projects, and experiences, many of which fail to reach critical mass (pilotitis). Semantically describing and documenting this implementation knowledge and the effectiveness of these tools will help to avoid the duplication of efforts, to reduce preventable implementation obstacles, and to assure that investments are targeted to the most important technological innovations. The RAFT annotation model, presented in this paper, enables to semantically describe all elements of various outputs and implementation projects that were developed, are used, or are part of the RAFT network. This model was initially developed to annotate various implementations and outputs of the RAFT network to facilitate knowledge documentation and sharing, and to be used as a proof of concept for the Implementome. The Implementome will be an interconnected knowledge system that enables the user to navigate on multiple dimensions through metadata annotated projects, people, and information, and can serve as base for consensus building, best practices and guidelines. The RAFT annotation model can be further developed to enable the annotation of outputs, implementations, people, initiatives, and projects of the digital health domain in general.

SMS reminders to improve adherence and cure of tuberculosis patients in Cameroon (TB-SMS Cameroon): a randomised controlled trial.

BACKGROUND: In Cameroon, the National Tuberculosis Control Program that applies selective directly observed treatments faces difficulties in its implementation for a lack of resources, leading to only 65% of patients with sputum smear-positive pulmonary tuberculosis being cured after 6 months of treatment. This study aimed to evaluate the effectiveness of daily Short Message Service reminders to increase adherence and the proportion of adult tuberculosis patients cured after 6 months of treatment. METHODS: A simple blinded, randomised controlled, multicentre study carried out in 12 Treatment and Diagnostic Centres of Yaoundé. The patients included were randomly assigned to two groups: patients in the intervention group received daily SMS reminders in addition to the usual treatment; those in the control group received the usual treatment only. The primary outcomes were the number and proportion of treatment success at 5 months, and the number and proportion of patients cured at 6 months. Data analysis was by intention to treat. RESULTS: Two hundred and seventy-nine participants were randomized into intervention group (n = 137) and control group (n = 142). At five months, there were 111 treatment success (81%) in the intervention group and 106 (74.6%) in the control group (OR = 1.45 [0.81, 2.56]; p = 0.203). At 6 months, there were 87 patients cured (63.5%) in the intervention group and 88 (62%) in the control group (OR = 1.06 [0.65, 1.73]; p = 0.791). The number of drop-outs at 6 months was 47 (34.3%) in intervention group, and 46 (32.4%) in the control group. 48.9% (23/47) and 39.1% (18/46) of these drop-outs were sputum-negative at 5 months. At three different appointments, there were no significant differences between the two groups in any secondary outcomes. Very high and similar satisfaction was found for general management of patients in both groups: 99.5 and 99.2% (p = 0.41). CONCLUSIONS: Our study suggests that SMS reminders do not increase treatment success and cure proportions. However, the low proportion of patients cured at 6 month may be an underestimation due to a high dropout rate between the fifth and the sixth months of treatment. Future trials should focus on reducing the dropout rate. TRIAL REGISTRATION: The trial was registered on the Pan-African Clinical Trials Registry ( PACTR201307000583416 of 22 July 2013) and the protocol was published.

How Regrouping Alerts in Computerized Physician Order Entry Layout Influences Physicians' Prescription Behavior: Results of a Crossover Randomized Trial.

BACKGROUND: As demonstrated in several publications, low positive predictive value alerts in computerized physician order entry (CPOE) induce fatigue and may interrupt physicians unnecessarily during prescription of medication. Although it is difficult to increase the consideration of medical alerts by physician through an improvement of their predictive value, another approach consists to act on the way they are presented. The interruption management model inspired us to propose an alternative alert display strategy of regrouping the alerts in the screen layout, as a possible solution for reducing the interruption in physicians' workflow. OBJECTIVE: In this study, we compared 2 CPOE designs based on a particular alert presentation strategy: one design involved regrouping the alerts in a single place on the screen, and in the other, the alerts were located next to the triggering information. Our objective was to evaluate experimentally whether the new design led to fewer interruptions in workflow and if it affected alert handling. METHODS: The 2 CPOE designs were compared in a controlled crossover randomized trial. All interactions with the system and eye movements were stored for quantitative analysis. RESULTS: The study involved a group of 22 users consisting of physicians and medical students who solved medical scenarios containing prescription tasks. Scenario completion time was shorter when the alerts were regrouped (mean 117.29 seconds, SD 36.68) than when disseminated on the screen (mean 145.58 seconds, SD 75.07; P=.045). Eye tracking revealed that physicians fixated longer on alerts in the classic design (mean 119.71 seconds, SD 76.77) than in the centralized alert design (mean 70.58 seconds, SD 33.53; P=.001). Visual switches between prescription and alert areas, indicating interruption, were reduced with centralized alerts (mean 41.29, SD 21.26) compared with the classic design (mean 57.81, SD 35.97; P=.04). Prescription behavior (ie, prescription changes after alerting), however, did not change significantly between the 2 strategies of display. The After-Scenario Questionnaire (ASQ) that was filled out after each scenario showed that overall satisfaction was significantly rated lower when alerts were regrouped (mean 4.37, SD 1.23) than when displayed next to the triggering information (mean 5.32, SD 0.94; P=.02). CONCLUSIONS: Centralization of alerts in a table might be a way to motivate physicians to manage alerts more actively, in a meaningful way, rather than just being interrupted by them. Our study could not provide clear recommendations yet, but provides objective data through a cognitive psychological approach. Future tests should work on standardized scenarios that would enable to not only measure physicians' behavior (visual fixations and handling of alerts) but also validate those actions using clinical criteria.

Reverse innovation experiences from the RAFT e-learning and telemedicine network.

Available infrastructure, resources, and provided services in low-and middle-income countries differ significantly from high-income countries. In healthcare for example, the uneven distribution of health professionals and lack of human resources are real barriers to equitable access to quality health care and services in most developing countries and particularly in Sub-Saharan Africa. As available resources are lower and infrastructure is les developed many services and tools that have been developed for a high-income context cannot be used or are not sustainably affordable in a low-income environment, which led to the development of tools and services that are affordable and appropriate for this context. This ranges from concepts of blended learning, over tools for distance education and diagnostic to hardware like affordable and robust ultrasound machines and services like mobile payment. Many of these solutions and tools also have a great potential to be utilized in a different context and some of them have been deployed in high-income countries.

The RAFT Telemedicine Network: Lessons Learnt and Perspectives from a Decade of Educational and Clinical Services in Low- and Middle-Incomes Countries.

BACKGROUND: The objectives of this paper are to (i) provide an overview of the educational and clinical experiences of the Réseau en Afrique Francophone pour la Télémédecine (RAFT) network, (ii) analyze key challenges and lessons learnt throughout a decade of activity, and (iii) draw a vision and perspectives of its sustainability. METHODS: The study was carried out following three main stages: (i) a literature review, (ii) the analysis of key documents, and (iii) discussions with key collaborators of the RAFT. RESULTS: Réseau en Afrique Francophone pour la Télémédecine has been offering an important quantity of educational, clinical, and public health activities during the last decade. The educational activities include the weekly delivery of video-lectures for continuing and post-graduate medical education, the use of virtual patients for training in clinical decision making, research training activities using ICTs and other e-learning activities. The clinical and public health activities include tele-expertise to support health professionals in the management of difficult clinical cases, the implementation of clinical information systems in African hospitals, the deployment of mHealth projects, etc. Since 2010, the RAFT has been extended to the Altiplano in Bolivia and Nepal (in progress). Lessons Learnt and Perspectives: Important lessons have been learnt from the accumulated experiences throughout these years. These lessons concern: social and organization, human resources, technologies and data security, policy and legislation, and economy and financing. Also, given the increase of the activities and the integration of eHealth and telemedicine in the health system of most of the countries, the RAFT network faces many other challenges and perspectives such as learning throughout life, recognition, and valorization of teaching or learning activities, the impact evaluation of interventions, and the scaling up and transferability out of Africa of RAFT activities. Based on the RAFT experience, effective integration and optimum use of eHealth and telemedicine in low- and middle-income countries (LMICs) health systems should take into account the context (resources, infrastructure, and funding), the needs of key stakeholders, and the results derived from theoretical and practical experience. The relevant items highlighted to illustrate the sustainability of the RAFT network and the analyses performed in this study, should serve as discussion basis for the development of eHealth and telemedicine in LMICs.

Medical and economic benefits of telehealth in low- and middle-income countries: results of a study in four district hospitals in Mali.

BACKGROUND: The aim of this study was to evaluate the impact of telehealth on 1) the diagnosis, and management in obstetrics and cardiology, 2) health care costs from patients' perspectives, 3) attendance at health centres located in remote areas of Mali. METHODS: The impact of telehealth on health care utilization, quality, and costs was assessed using a five-point Likert-scale based questionnaire consisting of three dimensions. It was completed by health care professionals in four district hospitals. The role of telehealth on attendance at health centres was also assessed based on data collected from the consultations logs before and during the project, between project sites and control sites. Referrals specific to the activities of the research study were also evaluated using a questionnaire to measure the real share of telehealth tools in increasing attendance at project sites. Finally, the cost savings achieved was estimated using the transport and lodging costs incurred if patients were to travel to the capital city for the same tests or care. RESULTS: The telehealth activities contributed to improving medical diagnoses in cardiology and obstetrics (92.6%) and the patients' management system on site (96.2%). The attendance records at health centres increased from 8 to 35% at all project sites during the study period. Patients from project sites saved an average of 12380 XOF (CFA Francs) or 25 USD (American dollar) and a maximum of 35000 XOF or 70 USD compared to patients from neighbouring sites, who must go to the capital city to receive the same care. CONCLUSION: We conclude that in Mali, enhanced training in ultrasound / electrocardiography and the introduction of telehealth have improved the health system in remote areas and resulted in high levels of appropriate diagnosis and patient management in the areas of obstetrics and cardiology. Telehealth can also significantly reduce the cost to the patient.

SMS reminders to improve the tuberculosis cure rate in developing countries (TB-SMS Cameroon): a protocol of a randomised control study.

BACKGROUND: Tuberculosis is a public health problem in Cameroon, just like in many other countries in the world. The National Tuberculosis Control Programme (PNLT) put in place by the state, aims to fight tuberculosis through the implementation of international directives (Directly Observed Treatment Short, DOTS). Despite the deployment of this strategy across the world, its implementation is difficult in the context of low-resource countries. Some expected results are not achieved. In Cameroon, the cure rate for patients with sputum positive pulmonary tuberculosis (TPM+) after 6 months is only about 65%, 20% below the target. This is mainly due to poor patient adherence to treatment. By relying on the potential of mobile Health, the objective of this study is to evaluate the effect of SMS reminders on the cure rate of TPM + patients, measured using 6-month bacilloscopy. METHODS/DESIGN: This is a blinded, randomised controlled multicentre study carried out in Cameroon. The research hypothesis is that sending daily SMS messages to remind patients to take their prescribed tuberculosis medication, together with the standard DOTS strategy, will increase the cure rate from 65% (control group: DOTS, no SMS intervention) to 85% (intervention group: DOTS, with SMS intervention) in a group of new TPM + patients. In accordance with each treatment centre, the participants will be randomly allocated into the two groups using a computer program: the intervention group and the control group. A member of the research team will send daily SMS messages. Study data will be collected by health professionals involved in the care of patients. Data analysis will be done by the intention-to-treat method. DISCUSSION: The achieving of expected outcomes by the PNLT through implementation of DOTS requires several challenges. Although it has been demonstrated that the DOTS strategy is effective in the fight against tuberculosis, its application remains difficult in developing countries. This study explores the potential of mHealth to support DOTS strategy. It will gather new evidence on the effectiveness of mHealth-based interventions and SMS reminders in the improvement of treatment adherence and the cure rate of tuberculosis patients, especially in a low-resource country such as Cameroon. TRIAL REGISTRATION: The trial is registered on the Pan-African Clinical Trials Registry (http://www.pactr.org) under unique identification number: PACTR201307000583416.

Developing clinical skills using a virtual patient simulator in a resource-limited setting.

OBJECTIVE: to measure the effect of training with a virtual patient (VP) simulation system on clinical skills of healthcare professionals in Africa. METHODS: A randomized controlled intervention was carried out at Yaounde Central Hospital (Cameroon). The intervention consisted of two groups training on one of the two clinical vignettes implemented in the VP simulator. Four actors were trained to play standardized patient (SP) roles. The clinical skills (performance score) of participants were assessed on both clinical vignettes using these SPs. RESULTS: Twenty medical students from FMSB were recruited. The difference in overall score was observed between participants who received training from the VP system (higher average) and those who did not receive the training (lower average). This difference is statistically significant, especially when the focus is on participants' scores in the relevant items for proper management of the case. CONCLUSION: This study suggests that the training with a medical consultation VP simulator can develop the operational clinical skills of the user.

Computer literacy and E-learning perception in Cameroon: the case of Yaounde Faculty of Medicine and Biomedical Sciences.

BACKGROUND: Health science education faces numerous challenges: assimilation of knowledge, management of increasing numbers of learners or changes in educational models and methodologies. With the emergence of e-learning, the use of information and communication technologies (ICT) and Internet to improve teaching and learning in health science training institutions has become a crucial issue for low and middle income countries, including sub-Saharan Africa. In this perspective, the Faculty of Medicine and Biomedical Sciences (FMBS) of Yaoundé has played a pioneering role in Cameroon in making significant efforts to improve students' and lecturers' access to computers and to Internet on its campus.The objective is to investigate how computer literacy and the perception towards e-learning and its potential could contribute to the learning and teaching process within the FMBS academic community. METHOD: A cross-sectional survey was carried out among students, residents and lecturers. The data was gathered through a written questionnaire distributed at FMBS campus and analysed with routine statistical software. RESULTS: 307 participants answered the questionnaire: 218 students, 57 residents and 32 lecturers. Results show that most students, residents and lecturers have access to computers and Internet, although students' access is mainly at home for computers and at cyber cafés for Internet. Most of the participants have a fairly good mastery of ICT. However, some basic rules of good practices concerning the use of ICT in the health domain were still not well known. Google is the most frequently used engine to retrieve health literature for all participants; only 7% of students and 16% of residents have heard about Medical Subject Headings (MeSH).The potential of e-learning in the improvement of teaching and learning still remains insufficiently exploited. About two thirds of the students are not familiar with the concept of e-leaning. 84% of students and 58% of residents had never had access to e-learning resources. However, most of the participants perceive the potential of e-learning for learning and teaching, and are in favour of its development at the FMBS. CONCLUSION: The strong interest revealed by the study participants to adopt and follow-up the development of e-learning, opens new perspectives to a faculty like the FMBS, located in a country with limited resources. However, the success of its development will depend on different factors: the definition of an e-learning strategy, the implementation of concrete measures and the adoption of a more active and participative pedagogy.

Virtual patient simulation: a comparison of two approaches for capacity building in Sub-Saharan Africa.

BACKGROUND: given the diversity of virtual patient simulation systems, this study provides a comparison of two different tools, in the perspective of deploying them for supporting initial and continuing medical education in Sub-Saharan Africa. METHOD: the evaluation was based on existing documentation, analysis of the data models, usage of implemented of virtual patient cases, and interviews with the domain experts. RESULTS: despite some shared similarities in their contents, there are many differences between the two applications especially in respect to their pedagogic models, technical architecture, types of interactions, feedback, and the learner's performance evaluations. DISCUSSION AND CONCLUSION: the implementation of learning activity based on virtual patient in a given context should consider these differences. According to their respective approaches, this study suggests that MVP is more suitable for novice learners whereas VIPS is more suitable for experienced learners.

Relevance and usability of a computerized patient simulator for continuous medical education of isolated care professionals in sub-saharan Africa.

OBJECTIVE: to explore the relevance and usability of using a computerized patient simulator as a tool for continuous medical education and decision support for health professionals in district hospitals in Sub-Saharan Africa. METHODS: based on the diagnosis pathway and decision analysis in uncertainty context, interactive clinical vignettes are developed using VIPS, a computerized patient simulator, taking into account clinical problem situations whose relevance was identified. Vignettes were adapted to take into account local epidemiology, availability of diagnostic and therapeutic resources, and local socio-cultural constraints. The evaluation on VIPS software was made by care professionals and students. RESULTS: a computerized patient simulator can be used to provide initial and continuing medical education in Sub-Saharan Africa. But many challenges exist. CONCLUSION: further research is needed to measure potential improvements in knowledge, skills, decision-making abilities as well as patient outcome.
