2EARLY MOBILISATION IN ICU
Introduction
At present, intense research focuses on the early mobilisation and rehabilitation of patients in
intensive care units (ICUs) with over 15 randomised controlled trials (RCTs) in the last
decade. The various mobilisation techniques include active and passive mobilisation and
transfer (Hodgson, Capell & Tipping, 2018). Early mobilisation of patients in the ICU
presents several benefits such as lowered ICU delirium, the reduced period under mechanical
ventilation, reduced time of stay in the ICU and muscle atrophy. However, early mobilisation
also poses risks to patients, specifically post-operation adults as they present operation-
related weakness and complications. The commonly identified risks include falls,
dislodgment of tubes, several intravenous and arterial accesses and increased nursing care
and interdisciplinary workforce (TEAM Study Investigators, 2015).
Rationale
The primary purpose of the study is to identify suitable evidence and outline an appropriate
protocol to evaluate the impact of early mobilisation of post-operative adult patients in
intensive care units (ICUs) in comparison to the current standards of complete bed rest and
sedation for 12 months.
Discussion
Background
The most common practice in all the ICUs across the globe is of complete bed rest and
sedation, particularly for patients after undergoing an operation. Complete bed rest after
operations in the ICU is associated with ICU-acquired weaknesses among the patients, which
affects the quality of life of the patient and might also result in specific life-long morbidities

(Hodgson, Capell & Tipping, 2018). Early mobilisation and rehabilitation is a proven
solution to reducing ICU-acquired morbidities and facilitate rapid functional independence of
the patients. Various researches and studies discuss the benefits of early mobilisation and
have become a widely researched topic. With the consistency of early mobilisation is
providing safe and feasible ICU outcomes, several international guidelines have been
suggested. The long-term advantages of early mobilisation, as reported by several studies
include functional improvement and quality of life (Castro-Avila et al., 2015). These
advantages encourage intensive research on applying this method to all patients that have
undergone operations to improve their overall quality of life.
Critical review question
After identifying the issue successfully, it is essential that the question under review be
precise to infer the types and range of the available evidence relevant to the issue adequately.
A well-structured research question is of utmost importance to emphasise the significance of
the research and develop an effective protocol for the study to be undertaken.
A known effective strategy is the PICO(T) framework. It stands for Population/Patient,
Intervention, Comparison, Outcomes and Time frame (Robb & Shellenbarger, 2014). It is a
suitable technique for evidence-based research and can be demonstrated as follows:

Intervention Early mobilisation
Comparison Complete bed rest
Outcome Improved patient outcome-functional status,

mechanical strength, length of stay and
quality of life
Time 12 months
The review question based on the table is:
In Intensive care units, is the early mobilisation of post-operative adult patients more
advantageous over complete bed rest over 12 months?
Search methodology
Studies suggest that a precise research question is imperative to obtain the most relevant
results. After finalising the research question, the researcher needs to expand their knowledge
on the topic by identifying suitable articles discussing the issue (Baskarada, 2014). Both
qualitative and quantitative studies can be used for research and analysing the patient
experience. The step-wise evaluation of the review question including obtaining appropriate
evidence, sampling, determining its size and the overall evaluation is determined
predominantly by the chosen research question.

Literature justification and appraisal
The articles are classified according to the reliability and validity of the evidence. The
various studies are explicitly sought based on peer-reviewed studies, systematic reviews and
meta-analyses. The preference for selecting relevant articles will be given to systematic
reviews as these provide data and information of the highest quality and are focused on the
particular topic of research with predefines inclusion and exclusion settings. These articles
consist of a rigorous review of available literature following appraisal and ranking foremost
in the scale of reliability (Leung, Trevena & Waters, 2014). After systematic reviews and
meta-analysis, study methods such as randomised controlled trials (RCTs) will be given the
next priority and are considered secondary to systematic reviews and meta-analysis. The
quality of the articles can be reviewed using the Critical Appraisal Skills Program (CASP)
(MacLean et al., 2017). However, randomised controlled trials are considered superior to the
case or anecdotal studies.

Literature review plan
The earmarks of the literature review include assembling the known and discovering the gaps
in research. The proposed strategy for the review consists of prioritising the obtained
evidence, critical appraisal of the articles and summarizing the outcomes of each study. The
National Health and Medical Research Council (NHMRC) provides the highest form of
evidence by carefully evaluating the literature and ranking them in nationally accepted orders
(Ingham-Broomfield, 2016).
Conclusion
A critical review of the relevant literature suggests that early mobilisation of adult intensive
care unit (ICU) patients is an essential element in improving patient outcomes in terms of the
length of stay, functional status, mechanical strength and quality of life. Available
quantitative data suggests that early mobilisation is achievable and the qualitative data
suggests that it is a safe option as well. Comprehensive research is required to identify full
inclusion and exclusion principles regarding early mobilisation and the different models in
performing early mobilisation to obtain the most accurate results.
