The effect of pre-course e-learning prior to advanced life support training: a randomised controlled trial.
ABSTRACT The role of e-learning in contemporary healthcare education is quickly developing. The aim of this study was to examine the relationship between the use of an e-learning simulation programme (Microsim, Laerdal, UK) prior to attending an Advanced Life Support (ALS) course and the subsequent relationship to candidate performance.
An open label, multi-centre randomised controlled study was conducted. The control group received a course manual and pre-course MCQ four weeks prior to the face to face course. The intervention group in addition received the Microsim programme on a CD. The primary outcome was performance during a simulated cardiac arrest at the end of the course. Secondary outcomes were performance during multiple choice exams, resuscitation skills assessments and feedback to Microsim programme.
572 participants were randomised (287 Microsim, 285 control). There were no significant differences in the primary outcome (performance during a standard cardiac arrest simulation) or secondary outcomes. User evaluations were favorable. 79% would recommend it to colleagues. 9% stated Microsim could replace the entire ALS course, 25% parts. Over 70% of participants' perceived that Microsim improved their understanding of the key learning domains of the ALS course.
Distributing Microsim to healthcare providers prior to attending an ALS courses did not improve either cognitive or psychomotor skills performance during cardiac arrest simulation testing. The challenge that lies ahead is to identify the optimal way to use e-learning as part of a blended approach to learning for this type of training programme.

ABSTRACT: Conventional educational systems seem to be improper throughout the cardiopulmonary resuscitation (CPR) teaching process. The most common causes of failed resuscitation are unfamiliarity with cardiopulmonary resuscitation algorithms, poor performance of leader of the CPR team and lack of skilled personnel, coordination among members during resuscitation, and responsibility of staff. Electronic learning, as a new educational method is controversial issue in medical education for improving physicians' practical knowledge and it is inevitable that further research on its effectiveness should be done. The present study is a prospective, pre- and post-educational, cross-sectional research, in which 84 interns were randomly divided into two groups. pre- and post- educational interventions that took place in the Department of Emergency Medicine, interns were evaluated by 21 multiple choice questions related to American Heart Association guidelineson cardiopulmonary resuscitation drugs. Questions were assessed in terms of routes for CPR drugs administration, CPR drug dosage forms, clinical judgment and appropriate CPR drug administration, and the alternative drugs in emergency situations. Data were analyzed by generalized estimating equations regression models and P < 0.05 was considered statistically significant. Evaluating the effectiveness of both educational methods revealed that the mean answering score for 21 questions before education was 7.5 ± 2.6 and no significant difference was observed in groups (P = 0.55). However, after education, the average scores significantly increased to 11.0 ± 3.9 (P < 0.001). Electronic learning method was not associated with considerable increase in the knowledge of interns in this group compared with the lecture-based group (P = 0.49). No significant differences were observed between electronic learning and lecture-based education in improving interns' knowledge of CPR drugs.Anesthesiology and pain medicine. 02/2014; 4(1):e15546.

Background: The role of e-learning in contemporary healthcare education is quickly
developing. The aim of this study was to examine the relationship between the use of an e-
learning simulation programme (Microsim™, Laerdal, UK) prior to attending an Advanced
Life Support (ALS) Course and the subsequent relationship to candidate performance.
Methods: An open label, multi-centre randomised controlled study was conducted. The
control group received a course manual and pre-course MCQ four weeks prior to the face to
face course. The intervention group in addition received the Microsim programme on a CD.
The primary outcome was performance during a simulated cardiac arrest at the end of the
course. Secondary outcomes were performance during multiple choice exams, resuscitation
skills assessments and feedback to Microsim programme.
Results 572 participants were randomised, (287 Microsim, 285 control). There were no
significant differences in the primary outcome (performance during a standard cardiac arrest
simulation) or secondary outcomes. User evaluations were favorable. 79% would recommend
it to colleagues. 9% stated Microsimcould replace the entire ALS course, 25% parts. Over
70% of participants‟ perceived that Microsimimproved their understanding the key learning
domains of the ALS course.
Distributing Microsim to healthcare providers prior to attending an ALS courses did not
improve either cognitive or psychomotor skills performance during cardiac arrest simulation
testing. The challenge that lies ahead is to identify the optimal way to use e-learning as part
of a blended approach to learning for this type of training programme.
Substantial healthcare resources are invested in resuscitation training. Currently the two /
three day European and UK Resuscitation Councils Advanced Life Support Course1-2 trains
over 20,000 healthcare professionals in advanced resuscitation techniques each year. The
curriculum design uses a variety of educational strategies to develop competency in
resuscitation based around knowledge, skill and behavioral development. Current practice
incorporates written material (a course manual issued four weeks prior to the course),
interactive lectures, small group teaching, group discussion and cardiac arrest simulation
A recent review by the International Liaison Committee for Resuscitation (ILCOR) indicated
the modifiable factors that influence outcome from cardiopulmonary arrest.3 Along with
guideline quality and the local chain of survival, the importance of educational interventions
was highlighted. In particular, the role „novel technologies‟ can play in enhancing learning
requires further exploration. E-learning is one such strategy and can offer multiple benefits
over „classical‟ learning techniques such as wide access and availability. Its use is rapidly
expanding in health-care training and is already integrated into many aspects of pre and post
graduate training. It has already been utilised in areas as diverse as basic surgical skill
ascertainment4 to the diagnosis of anaemia5, or improving management of epistaxis.6 Whilst
evidence from randomised controlled trials conducted has been generally positive there is a
lack of clarity over whether the purported theoretical benefits will translate from research into
clinical improvements.7 This however is not unique to e-learning, as it has proven extremely
difficult to establish this causal relationship.
Interest in e-learning and alternative educational strategies targeted at resuscitation training
has benefited from the ILCOR statement, the challenge now is establishing the potential
efficacy of such novel interventions. Reported positive outcomes8-9 do not seemingly dilute
concerns about how this then directly leads to improved practical performance10 and
knowledge.11 Thus embedding such a blended learning approach as common place and a
viable alternative to traditional learning methods requires further study.
Microsim (Laerdal, Stavanger) is a multi-media computer simulation programme which
provides structured training and feedback on medical emergencies and advanced resuscitation.
Different modules cover each of the five ALS learning domains (recognition of the critically
ill patient and prevention of cardiac arrest, rhythm recognition, resuscitation skills,
resuscitation treatment algorithms, post resuscitation care) and interactive simulations present
the user with a virtual patient in or at risk of cardiac arrest, requiring them to lead a
resuscitation team in their assessment and management. Detailed structured feedback on
performance is provided, and links to the course manual help underpin learning.
The aim of this study was to evaluate the efficacy of pre-course preparation with Microsim on
the Advanced Life Support (ALS) course learning outcomes and explore user perceptions and
reactions to the learning material. The data from this study have also been used to validate a
scoring system for the cardiac arrest scenario test. 12
Design and Participants
An open label randomised controlled study was conducted. Individuals undertaking the ALS
course at 9 UK Hospitals over a ten month period (March to December 2007) were eligible
for inclusion. All participants provided written informed consent.
Participants were randomised at each site to the e-learning or control arm ( allocation 1:1) in
blocks of six. Randomisation was stratified by course centre. Participants in the e-learning
arm received a CD version of the Microsimcomputer programme plus the standard supporting
ALS course material four weeks in advance of the course (ALS manual, pre-course MCQ).
The CD had been specifically configured to ensure consistency with the ERC / Resuscitation
Council (UK) guidelines. The feedback contained hyperlinks to an electronic version of the
course manual. Those in the control arm received the standard course material alone.
The study was approved by the South Birmingham Research Ethics Committee.
Outcome and Data Collection
The effect on learning outcomes was assessed by various modalities. Knowledge was
assessed at the start and end of the course a pre- and post-course multiple choice paper
(MCQ). The MCQ‟s contain 30 stems to which 4 true / false choices are presented giving 120
items in total. Internal evaluation of over 5000 MCQ papers by the Resuscitation Council
(UK) found the papers are both reliable and valid assessment tools (data on file).
Airway management, patient assessment, defibrillation and CPR skills are tested using an
outcome based assessment tool. Participants are allowed as many assessment attempts during
the course as required to allow them to achieve the necessary standard.
Knowledge, skills and decision making are all tested during the cardiac arrest simulation test
(CASTest). The focus of this is in establishing a candidates ability to lead a resuscitation team
during a simulation involving the care of a critically ill patient that deteriorates into cardiac
All practical assessments were scored by instructors rating overall performance using a
validated four point scale (1=unsatisfactory; 2=borderline; 3= acceptable; 4 = excellent) (see
Pass/fail decisions were made on global assessment by paired instructors utilising pre-defined
criteria. Instructors were not told whether candidates had been allocated to the Microsim or
control arm. Instructors evaluated performance individually and agreed a joint score by
consensus between the pair. If they failed to agree on a score the Course Director acted as the
final arbiter. Candidates that performed consistently well during the course were assessed by
the faculty as a whole for consideration for nomination for instructor training. Judgements
regarding instructor potential took place at end-of-course faculty meetings. Multiple criteria
including communication, enthusiasm, interactivity and ability to function as a team member
Feedback on experiences of using the MicrosimCD was collected by questionnaire from
participants in the e-learning arm at the start of the course. Candidates were asked to rate both
specific aspects of programme utilisation (ease and length of use) and to provide opinions on
their perceived value of Microsim.
Sample size estimation: In order to determine sample size population, previous ALS course
data was examined. Two outcomes were used, firstly results from over 8000 multiple choice
test papers were analysed. The average pass mark for the Pre course paper is 87.2% (standard
deviation 6.63) and for the post course paper is 88.1 (standard deviation 6.8). On this basis,
we calculated that 40 participants in each group would be required to detect a 5% difference
in MCQ score with 90% power at a significance level of 0.05. Secondly from the published
CASTest evaluation16 we established the pass rate for the cardiac arrest scenario tests was
74%. In order to realise a 10% difference in CASTest pass rate estimates a study cohort of
520, with 260 participants in each arm.
Ordinal data (performance ratings) were analysed using Mann Whitney U test. Chi-squared
test was employed for categorical data. A priori a P value of 0.05 was considered significant.
All analysis was performed with SPSS statistical package version 15.
Six hundred and fifty seven people were screened for eligibility to participate. From this 572
people were randomized to the Microsim CD (n=287) or standard (285) arms. Of these 275
and 276 people returned data for analysis. The CONSORT flow diagram (figure 1) describes
participant flow through the study.
There were no significant differences in demographics between the groups. In the Microsim
arm 183(66%) were doctors; 48(17%) nurses; 6(2%) other; 39 (14%) did not respond to this
domain. The standard group comprised 169(62%) doctors; 53(19%) nurses; 9(3%) other;
43(16%) did not respond. 62(22%) and 55(20%) described their role as senior (consultant /
sister) whilst 137(49%) and 136(50%) described their role as junior respectively.
Pre- and post-course MCQ scores in both arms no CD vs CD were not significantly different
(mean (SD) 106.2 (9.2) vs 105.5 (9.2), P=0.5 and 101.9 (13.8) vs. 101.4 (13.9), P=0.7).
There was no difference in overall performance ratings between groups for airway(P=0.6),
initial assessment (P=0.4) and rhythm (IAR) and CASTest outcomes (P=0.8). Overall
pass/fail (no CD vs CD arm 91.8% vs 93.6%, P=0.4). and identification of instructor
potential (8.9% vs 8.2%, P=0.8).
Questionnaires were returned by 36% (n=100). Of these, 64% used the CD prior to attending
the course. Three quarters (75%) of respondents found the installation process easy and were
able to use the programme without difficulty. The median duration of use was 2 hours, (range
1-20h). 65% found installation easy. 79% would recommend the MicrosimCD to colleagues
undertaking the ALS course, finding it useful for pre-course preparation. Only a small
proportion (9%) agreed with the statement that Microsimcould replace the entire ALS course.
However a quarter of users reported that the CD could replace parts of the ALS course.
Participants‟ perceptions on the value of Microsimin improving understanding in specific
learning domains are provided in Figure 2.
Microsim represents a novel, computer-based approach to augmenting candidate preparation
for resuscitation training. When used as part of the pre-course preparation for ALS it was
enthusiastically received by most of the candidates. Over 80% believed Microsim improved
their understanding of ALS theory and skills, a similar number would recommend the
programme to colleagues and a quarter felt it could replace parts of the existing course.
Despite the positive feedback, allocation to the Microsim arm of the study produced no
significant improvement in learning outcomes.
E-learning offers a number of advantages over alternatives such as face to face training or
learning from textbooks.19 It is convenient, flexible and placed fewer geographical and
temporal constraints on students and tutors. Standardised learning tools ensure a more
consistent educational experience, as all students are exposed to similar resources (regardless
of an individual centre‟s capabilities) and are able to learn at their own pace. E-learning
systems have previously been trialled in a number of settings to facilitate resuscitation
training.11, 13 Monsieurs et al described the use of a CD-Rom basic life support programme. It
improved users attitudes and assessment skills but compared to standard training was inferior
for the acquisition of the psychomotor skills required for CPR.13 A multi-media advanced
resuscitation training course involving a video and computer game was compared to a 3 hour
face to face simulation course or reading a text book in a randomised controlled trial. The
multi-media course improved short term cognitive outcomes but was inferior to the face to
face simulation training when performance was tested during a simulated cardiac arrest.14 In
contrast a combined e-learning / face to face paediatric advanced life support course achieved
similar learning outcomes to a two-day face to face course.15
The approach in this study was different in that the e-learning material was used to
supplement rather than replace face to face training and used mostly case-based scenarios to
deliver the educational content. This approach improved upon traditional techniques which
were primarily aimed at imparting purely factual information.18 The programme utilised
advanced graphics and text with high quality sound. These features are especially relevant to
this type of training which can be difficult to conceptualise. This approach enables the
learners to experience a highly realistic virtual reality, immersing them in interactive clinical
scenarios that demand a response to patient assessment and management.. Learners can
personalise their learning experience by progressing through material at their own pace with
the freedom to pause, repeat or seek assistance if needed. The provision of individualised
feedback based on performance allows users to identify their areas of strength and weakness,
allowing focused learning that potentially maximised their development.
Given this, it is disappointing, that the use of Microsim did not lead to a measurable
improvement in learning. There are a number of potential explanations for this finding. Data
were analysed on an “intention to treat” basis, yet only two thirds actually used the CD. Those
that used the CD did for an average of only 2 hours. This represents a relatively brief period,
and likely did not allow full exploitation of the potential of Microsimas a learning tool.
Equally, the assessments used to determine learning outcomes for the ALS course may not
have captured subtle improvement in participants reasoning and decision making skills, which
may have been enhanced by the programme.
The relatively low uptake and usage of the e-learning materials is not unique to this study16.
Barriers to uptake of e-learning programmes include time constraints, low confidence with the
use of computers, limited experience with the use of the internet, absence of social interaction
and lack of personal discipline17-19. The use of e-learning materials can be enhanced by
providing prompts or reminders to learners to review material20 and allowing work based
study time19, 21. Usage is also improved if materials are well presented and easy to navigate22,
the course provides a certificate of accreditation18, users can assess and validate their own
knowledge22 and have a mechanism for support / feedback from faculty22.
A quarter of learners encountered difficulty with installation or technical problems whilst
using the programme which may have contributed to the sub-optimal usage. This occurred
despite the availability of a technical support line designed to provide assistance with these
difficulties. There are a wide range of computer systems in use across healthcare sectors and
few have access to the latest versions of hardware and software. The importance of protecting
healthcare records and information further means that unrestricted internet access is rarely
available and the ability to install programmes to computers in hospitals can be limited. It is
important that these factors are considered during the development of e-learning materials.
Whilst e-learning offers a number of positive opportunities, the drawbacks must be
acknowledged. Preparing e-learning materials are generally labour intensive and time-
consuming to produce and render operational, yet this may be tempered by the knowledge
that only incremental costs are needed to expand their use or modify them. Equally, barriers
may exist with regards to integration with existing learning tools, cultural resistance from
educators, and both theoretical and genuine candidate concerns over learning in isolation in
the absence of social interaction.1123 Nevertheless, despite these apparent difficulties, it is
likely that with the passage of time, and greater learner and teacher familiarisation with e-
learning such impediments will diminish.
Limitations and Further Work
Limitations are apparent with the study. The use of questionnaires to obtain feedback exposes
the data to responder and recall bias. Only 35% of questionnaires were returned and we must
assume that similar response patterns would prevail in the remainder of the group. A potential
strength and limitation of the study is the fact that it was analysed on an intention to treat
basis – thus reporting the effects of how the widespread distribution of Microsim would affect
learning outcomes. However the study did not assess if there was a dose response
relationship between the amount of time spent using the system and learning outcomes.
Further work is required to clarify whether the use of Microsim or other e-learning tools can
improve learning outcomes and also in what specific competencies it‟s use is most effective
in. Equally it will be necessary to assess whether e-learning can offer a more efficient medium
for delivering certain aspects of advanced life support training, potentially replacing or
modifying certain traditional learning resources utilised in the course22.
The e-learning micro-simulation programme Microsim was positively evaluated by
participants from advanced life support courses. In this study, distributing Microsim to
healthcare providers prior to attending an Advanced Life Support courses did not improve
either cognitive or psychomotor skills or performance during cardiac arrest simulation testing.
The challenge that lies ahead is to identify the optimal way to use e-learning as part of a
blended approach to learning for this type of training programme.
