The nature and sources of the emotional distress felt by intensivists and the burdens that are carried: A qualitative study.

BACKGROUND: Work in intensive care units is often traumatic and emotionally distressing, sometimes leading to growth but at other times to negative outcomes such as worker burnout and mental illness. The type and origin of distresses to intensivists has been poorly characterised in the literature. This evidence gap makes it difficult to develop tailored educational process or cultural interventions for all who work within the specialty. OBJECTIVES: The aim of this study was to elicit the nature and sources of workplace emotional distress in an international sample of intensivists. METHOD: Interviews were undertaken with experienced intensivists in Australia and Israel related to the basis of workplace distress. These were transcribed and qualitatively thematically analysed. RESULTS: In 2018, 19 intensivists participated in the study. Several key themes emerged from data analysis, some relating to clinical work, such as catastrophic patient outcomes, and some relating to interpersonal and systems-level challenges. Navigating complex interpersonal dynamics with carers and staff, both within and outside the intensive care unit team, caused substantial emotional burden. CONCLUSIONS: Many factors contribute to workplace stress for doctors in the intensive care setting. In elucidating common reactions to these stressors, we have attempted to normalise responses. We further note that the skill sets relevant to the many challenges identified are generally missing in medical training curricula. It may be prudent to consider their inclusion in the future.

Observational Study Exploring the Efficacy and Effectiveness of a New Model of Peer-Assisted Simulation-Based Learning Clinical Placement.

(1) Background: Immersive simulation-based learning is relevant and effective in health care professional pre-licensure training. Peer-assisted learning has reciprocal benefit for the learner and the teacher. A fully simulated model of fieldwork placement has been utilised at Curtin University since 2014, historically employing full-time faculty supervisors. Due to the COVID-19 pandemic in 2020, traditional clinical placement availability diminished. (2) Methods: This mixed-methods prospective observational study aimed to translate the existing faculty-led placement for penultimate-year physiotherapy students to a peer-taught model, thereby creating new teaching placements for final-year students. Final- and penultimate-year physiotherapy students undertook the fully simulated fieldwork placement either as peer learners or peer teachers. The placement was then evaluated using four outcome measures: The 'measure of quality of giving feedback scale' (MQF) was used to assess peer learner satisfaction with peer-teacher supervision; plus/delta reflections were provided by peer teachers and faculty supervisors; student pass/fail rates for the penultimate-year physiotherapy students. (3) Results: For 10 weeks during November and December 2020, 195 students and 19 faculty participated in the placement. Mean MQF scores ranged from 6.4 (SD 0.86) to 6.8 (SD) out of 7; qualitative data reflected positive and negative aspects of the experience. There was a 4% fail rate for penultimate-year students for the placement. Results suggested that peer learners perceived peer-led feedback was of a high quality; there were both positives and challenges experienced using the model. (4) Conclusions: Physiotherapy students effectively adopted a peer-taught fully simulated fieldwork placement model with minimal faculty supervision, and comparable clinical competency outcomes.

The Different Challenges in Being an Adult Versus a Pediatric Intensivist.

There is little current research comparing stress, burnout, and resilience in pediatric and adult intensive care practitioners. This article analyzes data derived from a 2018 qualitative study of burnout and resilience among ICU providers to explore differences that may exist between the pediatric and adult domains of practice. DESIGN: This study represents a thematic subanalysis of textual data derived from a larger qualitative study of ICU provider burnout and resilience. SETTING: Six international critical care units (Australia, Israel, United States). SUBJECTS: Physicians working at the above sites who had been practicing as intensivists for a minimum period of 4 years. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Data were collected using a semistructured interview process, and resulting transcripts were analyzed using postpositivist framework analysis. A secondary analysis was then performed separately on pediatric and adult datasets using the initial coding framework as a template. Three themes related to perceived differences were noted: differences in the patient characteristics within both cohorts, differences in the relationships between staff and family, and personal biases of individual intensivists. Pediatric and adult practitioners differed in their perceptions of the patient's perceived responsibility for their illness. Emotional responses to the stressor of child abuse (particularly as they related to clinician-family relationships) also differed. The stress of dealing with family expectations of patient survival even in dire circumstances was unique to the pediatric environment. Both pediatric and adult practitioners commented on the perceived difficulty of assuming the opposite role. Differences in life expectancy and mortality rate were significant factors in this. CONCLUSIONS: Although similar stressors exist within each group, meaningful differences in how these are perceived and personally processed by individual clinicians exist. Better understanding of these differences will assist attempts to enhance the resilience and provide career guidance to aspiring intensive care clinicians.

Advice for doctors working or planning to work in intensive care: summation from a qualitative study.

Healthcare personnel who work for prolonged periods in highly stressful environments are susceptible to the effects of these stressors and the cumulative nature of their exposure. The term 'burnout' has been coined to describe a constellation of symptoms related to work, organisational and personal issues occurring in individuals with no prior history [1]. Burnout has been described as particularly prevalent in the critical care setting [2-4]; it affects not only the health and wellbeing of those individuals experiencing the deleterious consequences, but also the quality of the care they provide [1]. There is significant literature that supports the worthiness of mentorship [5-7] throughout medical training. Following on from our paper exploring the behavioural responses of intensivists to stressors encountered working in the intensive care environment [8], the aim of this study was to elicit the advice senior intensivists might offer others on dealing with the stresses of a career in intensive care.

Delivering Simulation Activities Safely: What if We Hurt Ourselves?

SUMMARY STATEMENT: Although a focus on the learner rightly remains in any teaching environment, the psychological safety of everyone involved in the conduct of experiential learning and critical academic scholarship is important. Education literature suggests that faculty are just as prone to psychological harm as their learners. This commentary describes adverse experiences from a simulation-based education event that took place at an Australasian interprofessional and cross-domain simulation workshop. Event facilitators explored the notion of the "safe container" but, in the process, were themselves exposed to psychological injury. We summarize an ostensibly complex simulation activity with unintended sequelae, the ethical concerns surrounding the faculty care, and from lessons learned, present an extended conceptualization of the safe container including broader parameters around the preparation of all involved in the delivery of simulation-based activities. Our goals in sharing this case is to encourage the community to become more vigilant regarding the unintended consequences of our simulation activities and to encourage open reporting and discussion of such incidents for the betterment of the field.

Ventilator hyperinflation determined by peak airway pressure delivered: A randomized crossover trial.

AIM: The aim of this study was to see if a more sophisticated ventilator hyperinflation protocol might result in more sputum clearance compared to manual hyperinflation. BACKGROUND: Hyperinflation has been used to mobilize lung secretions in mechanically ventilated patients in the intensive care unit setting for almost 50 years. In the past decade, rather than using a bag external to the ventilator circuit to deliver hyperinflation (known as "bagging" or "manual hyperinflation"), a new technique has evolved using existing ventilator circuitry (known as "ventilator hyperinflation"). One conservative ventilator hyperinflation protocol has demonstrated equivalence with manual hyperinflation in sputum clearance. DESIGN: A randomized crossover study. METHOD: Patients received manual hyperinflation and ventilator hyperinflation in two randomly ordered treatments on the same day by the same physiotherapist, using a ventilator hyperinflation protocol involving titration of hyperinflation according to airway pressure. RESULTS: Between 2013 and 2018, 48 patients were enrolled in the study. Physiotherapy treatment using ventilator hyperinflation yielded significantly more wet weight sputum (median 2.84 g, IQR 1.81, 4.22) than treatment using manual hyperinflation (median 1.5 g, IQR 0.73, 2.31, P < .001), without significant differences in secondary measures. CONCLUSIONS: A more sophisticated approach to the titration of the volume delivered using ventilator hyperinflation relative to the airway pressure resulted in greater wet weight sputum cleared during physiotherapy treatment. RELEVANCE TO CLINICAL PRACTICE: The results presented in this paper demonstrate that the application of ventilator hyperinflation using peak airway pressure rather than tidal volume may be superior in facilitating sputum clearance and improved oxygenation without patient harm.

Can student-peers teach using simulated-based learning as well as faculty: A non-equivalent posttest-only study.

BACKGROUND: Peer-assisted learning has an important place in the delivery of health care education with benefits for both the learners and the peer teachers. Simulation-based learning (SBL) is evolving in healthcare professions training and academic programs as a modality that conveys realism and fidelity through immersion. OBJECTIVES: The primary aim was to compare physiotherapy student's motivation to learn between a conventional faculty-led SBL activity and the same SBL activity delivered by trained final year physiotherapy peer tutors. METHODS: Physiotherapy students from two Universities (n = 226) undertook a SBL learning activity (either faculty led or peer led) and completed the Instructional Materials Motivation Scale questionnaire to assess motivation to learn. RESULTS: There was a high level of learner motivation in all learning groups, with significantly higher learner satisfaction (p < 0.001) and lower attention (p < 0.001) in student-led SBL than faculty-led SBL. CONCLUSIONS: This study has highlighted the potential to incorporate peer-assisted and simulation-based learning together in the development of future educational activities in health care training.

An Observational Study of a Simulation-Based Cross-Discipline Learning Activity Between Theater Arts and Physical Therapy Students.

INTRODUCTION: Professional actors are often used to portray simulated patients during healthcare professional training. This study aimed to create an activity where physical therapy (PT) and theater arts (TA) students could address discrete learning outcomes in a common setting with mutual benefit. METHODS: Mixed methods observational study of 246 university students (201 PT, 45 TA) undertaking a scenario involving the provision of a clinical history. All students completed a 5-question qualitative survey relating to the activity, and each group scored themselves and each other using an observer rubric rating performance from 1 (do not agree) to 10 (agree). RESULTS: For PT students, the range of means (SDs) across the five questions were significantly different (P < 0.001) with 6.2 (1.6) to 6.8 (1.4) for self-assessment and 8.2 (1.4) to 8.7 (1.1) for TA assessment of PT. For TA students, across all repetitions and all questions, the mean (SD) was 7.6 (1.5) for self-assessment and 7.9 (1.2) for PT assessment of TA, representing a significant difference (P < 0.001). After initial enactment, there was a significant improvement in TA self-assessment of performance (P = 0.002), but thereafter, there was no significant difference over time (P = 0.114).Qualitative data analysis revealed the following three themes common to both groups: worthiness, authenticity/realism, and anxiety/confidence. The PT students also identified history-taking skills and the importance of patient/PT relationships. The TA students identified learning around character portrayal, improvisation, and concentration. CONCLUSIONS: This study describes a simulation-based learning activity undertaken within existing infrastructure with complementary learning objectives for both TA and PT students that was realistic and engaging.

The influence of a full-time, immersive simulation-based clinical placement on physiotherapy student confidence during the transition to clinical practice.

BACKGROUND: Novice students may have limited learning opportunities during their early exposure to complex clinical environments, due to the priorities of patient care. Immersive, high-fidelity simulation provides an opportunity for physiotherapy students to be exposed to relatively complex scenarios in a safe learning environment before transitioning to the clinical setting. The present study evaluated the influence of immersive simulation on student confidence and competence. METHODS: Sixty penultimate year physiotherapy students completed an 18-day full-time immersive simulation placement. The placement involved students spending 6 days working in each of three core practice areas (cardiopulmonary, musculoskeletal, neurological) in which they interacted with simulated patients portrayed by professional role-play actors. The patient scenarios were developed by groups of expert practitioners and incorporated full documentary and imaging information. Students completed a questionnaire to evaluate their confidence in the clinical environment at the start and completion of each 6-day rotation. Their clinical competence was evaluated at the end of each 6-day rotation using the Assessment of Physiotherapy Practice (APP) tool. In a secondary analysis, the clinical competence of this cohort was evaluated in comparison to a matched cohort of students from the same year group that had not completed an immersive simulation placement. RESULTS: Student confidence improved significantly in each 6-day rotation (p < 0.001); however, it reduced again at the commencement of the next rotation, and there was no cumulative improvement in confidence over the 18-day placement (p = 0.22). Students who had completed the immersive simulation placement achieved higher APP (p < 0.001) scores in an evaluation of their competence to practice during their subsequent clinical placement. CONCLUSION: Immersive simulation provides a beneficial learning environment to enable physiotherapy students to transition from university-based education to working in the clinical environment.

Do acute hospitalised patients in Australia have a different body mass index to the general Australian population: a point prevalence study?

Objective The aim of the present study was to provide a current snapshot of the body mass index (BMI) of the entire patient cohort of an Australian tertiary hospital on one day and compare these data with current published Australian and state (Western Australia) population norms. Methods A single-centre prospective point prevalence study was performed whereby BMI was calculated following actual measurement of patient weight (nurse) and height (physiotherapist) on one day during 2015. Variables were summarised descriptively, and one-way analysis of variance was used to investigate the relationship between continuous BMI and hospital speciality. Multivariate Cox proportional hazards regression was used to analyse the time to leaving hospital, where those who died were censored at their date of death. Results Data were collected from 416 patients (96% of the hospital population on that day). The mean (± s.e.m.) BMI across the whole hospital population was 26.6±2.2kgm-2, with 37% of patients having normal BMI, 8% being underweight, 32% being overweight, 19% being obese and 4% being severely obese. Comparison with both national and state population norms for 2014-15 reflected higher proportions of the hospital population in the underweight and extremely obese categories, and lower proportions in the overweight and obese categories. There was no significant difference in BMI across medical specialties. Conclusions Despite health warnings about the direct relationship between illness and being overweight or obese, the results of the present study reveal fewer hospitalised patients in these BMI categories and more underweight patients than in the non-hospitalised general Australian population. Being overweight or obese may offer some protection against hospitalisation, but there is a point where the deleterious effect of obesity results in more extremely obese individuals being hospitalised than the proportion represented in the general population. What is known about the topic? Although there is significant current published data relating to general Australian population BMI, there is little pertaining specifically to the hospitalised population. Accordingly, although we know that as an affluent Western country we are seeing growing rates of overweight and obese people and relatively few underweight or undernourished people in the general population, we do not know whether these trends are mirrored or magnified in those who are sick in hospital. We also know that although caring for obese patients carries a significant burden, there is the suggestion in some healthcare literature of an 'obesity paradox', whereby in certain disease states being overweight actually decreases mortality and promotes a faster recovery from illness compared with underweight people, who have poorer outcomes. What does this paper add? This paper is the first of its kind to actually measure and calculate the BMI of a whole tertiary Australian hospital population and provide some comparison with published Australian norms. On average, the hospital cohort was overweight, with a mean (± s.e.m.) BMI of 26.6±2.2kgm-2, but less so than the general population, which had a mean BMI of 27.5±0.2kgm-2. The results also indicate that compared with state and national norms, underweight and extremely obese patients were over-represented in the hospitalised cohort, whereas overweight or obese patients were under-represented. What are the implications for practitioners? Although only a single-centre study, the case-mix and socioeconomic catchment area of the hospital evaluated in the present study suggest that it is a typical tertiary urban West Australian facility and, as such, there may be some implications for practitioners. Primarily, administrators need to ensure that we are able to accommodate people of increasing weight in our hospital facilities and have the resources with which to do so, because, on average, hospitalised patients were overweight. In addition, resources need to be available for managing the extremely obese if numbers in this subset of the population increase. Finally, practitioners may also need to consider that although the management of underweight and undernourished patients may be less of a physical burden, there are actually more of these patients in hospital compared with the general population, and they may require a different package of resource utilisation.

The prevalence of back pain in patients in one Australian tertiary hospital population.

OBJECTIVES: The aims of the present study were to provide back pain (BP) point prevalence data from inpatients at an Australian tertiary hospital on one day, and compare this with Australian non-hospitalized population prevalence data; to collect data around the development of BP throughout hospital admission; and to analyse the association between BP and past history of BP, gender, age, admission specialty and hospital length of stay (LOS). METHODS: This was a single-site, prospective, observational study of hospitalized inpatients on one day during 2016, with a subsequent survey over the following 11 days (unless discharge or death occurred sooner). RESULTS: Data were collected from 343 patients (75% of the hospitalized cohort). A third of patients (n = 108) reported BP on admission, and almost a fifth (n = 63) developed new BP during their hospitalization. Patients who described BP at any time during their hospital stay had a higher chance of having had a history of BP, with odds increasing after adjustment for age and gender (odds ratio 5.89; 95% confidence interval (CI) 3.0 to 11.6; p < 0.001). After adjusting for age and gender, those experiencing BP had a significantly longer LOS (median 13 days; CI 10.8 to 15.3) than those who did not (median 10 days; CI 8.4 to 11.6; p = 0.034). CONCLUSIONS: Hospital LOS for patients who complained of BP at any time during their admission was 3 days longer than those who had no BP, and a history of BP predicted a higher likelihood of BP during admission. Screening of patients on admission to identify any history of BP, and application of a package of care including early mobilization and analgesia may prevent the onset of BP and reduce LOS.

Challenging conversations with simulated patients.

BACKGROUND: Simulation-based learning (SBL) activities in the health sciences provide students with opportunities to interact with realistic patients and environments. This study aimed to develop and then implement a novel activity using simulation for a large group of mostly millennial physiotherapy students, to enhance their ability to communicate with a challenging patient and to assess their motivation to learn. METHODS: Students enrolled in a second-year communication unit were invited to participate in a non-compulsory unique SBL activity in groups of four for 40 minutes, undertaking two 5-minute simulation scenarios and two debriefing sessions. On completion of the activity, 140 students scored their motivation to learn during the activity using the Instructional Materials Motivation Scale (IMMS) questionnaire. RESULTS: Of the physiotherapy students enrolled in the unit, 83 per cent took part in the SBL and 100 per cent of the participants completed the follow-up survey. Mean scores for each subscale ranged from 3.8 to 4.0, reflecting that students agreed more than moderately with the statements made in the scale. The median total IMMS score for all students was 149, well above the published median total score of the scale (108). Simulation-based learning activities provide students with opportunities to interact with realistic patients and environments DISCUSSION: The SBL activity model was successfully implemented and received positively by the students in terms of their motivation to learn. It gained the attention of participants by providing an opportunity to practise the non-technical skill of 'communicating with patients', previously learned in the classroom, in a simulated realistic environment and by using a design that seemed to consider the needs of the millennial generation.

Prevalence of obesity and the effect on length of mechanical ventilation and length of stay in intensive care patients: A single site observational study.

OBJECTIVES: To provide a snapshot of the prevalence of abnormal body mass index (BMI) in a sample of intensive care unit (ICU) patients; to identify if any medical specialty was associated with abnormal BMI and to explore associations between BMI and ICU-related outcomes. BACKGROUND: Obesity is an escalating public health issue across developed nations but there is little data pertaining to critically ill patients who require care that is expensive. METHODS: Retrospective observational audit of 735 adult patients (median age 58 years) admitted to the Sir Charles Gairdner Hospital 23 bed tertiary ICU between November 2012 and June 2014. Primary outcome measure was patient BMI: underweight (<18.5kg/m2), normal weight (18.5-24.99kg/m2), overweight (25-29.99kg/m2), obese (30-39.99kg/m2) or extreme obese (40kg/m2 or above). Other measures included gender, acute physiology and chronic health evaluation II score, admission specialty, length of mechanical ventilation (MV), length of stay (LOS) and mortality. RESULTS: Compared to the general population there was a higher proportion of obese patients within the cohort with the majority of patients overweight (33.9%) or obese (36.5%) and median BMI of 27.9 (IQR 7.9). There were no significant differences between specialties for BMI (p=0.103) and abnormal BMI was not found to impact negatively on mortality (ICU, p=0.373; hospital, p=0.330). Normal BMI patients had shorter length of MV than other BMI categories and the impact of BMI on ICU LOS was dependent on length of MV. Overweight patients ventilated for five days or more had a shorter LOS, and extremely obese non-ventilated patients had a longer LOS, compared to normal weight patients. CONCLUSIONS: Although the obesity-disease relationship is increasingly complex and data presented reflects categorical BMI for patients admitted to a single ICU site it may be important to consider the cost implications of caring for this cohort especially with regard to MV and LOS.

Prevalence of obesity in an intensive care unit patient population.

BACKGROUND: The Australian health survey (2011-2012) reported that 63.4% of Australian adults were overweight or obese. Critical care medicine is expensive, with intensive care unit (ICU) services accounting for a substantial proportion of total hospital costs. These costs may be multiplied in the overweight cohort. OBJECTIVES: The primary aim was to compare the body mass index (BMI) of a critically ill ICU patient cohort to Australian population norms in order to see if overweight people were over-represented. The secondary aim was to identify if any medical specialty was associated with overweight patients. METHODS: A retrospective observational case note audit of 230 ICU patients between November 2012 and August 2013, with BMI as the primary outcome measure. RESULTS: Approximately 75% of the cohort were overweight or obese (median BMI 28.7; IQR 25.0-32.7) representing a rate 12% higher than Australian normative data. Based on population, this equates to an estimated additional 5279 unanticipated overweight or obese ICU patients at our facility during 2013. CONCLUSIONS: This study has shown that Australian ICU patients may have higher BMI than those of the general Australian population, and therefore there may be unanticipated costs associated with their care. No medical specialty was associated with higher BMI than another.

Performance of manual hyperinflation: consistency and modification of the technique by intensive care unit nurses during physiotherapy.

AIMS AND OBJECTIVES: To assess the consistency and safety of manual hyperinflation delivery by nurses of variable clinical experience using a resuscitator bag during physiotherapy treatment. BACKGROUND: Manual hyperinflation involves the delivery of larger than normal gas volumes to intubated patients and is routinely used by nurses in collaboration with physiotherapists for the management of retained sputum. The aim is to deliver slow deep breaths with an inspiratory hold without unsafe airway pressures, lung volumes or haemodynamic changes. In addition, nursing staff should be able to 'feel' differences in resistance and adjust their technique accordingly. DESIGN: Prospective observational study utilising the simulation of a mechanically ventilated patient. METHODS: Thirty-three nurses delivered manual hyperinflation to a SimMan3G mannequin who had three distinct lung scenarios applied (normal; asthma; Acute Respiratory Distress Syndrome) in randomised order during simulated physiotherapy treatment. Respiratory rate, tidal volume (Vt ), mean inspiratory flow rate (Vt /Ti), and peak airway pressure data were generated. RESULTS: Over all scenarios, mean respiratory rate = 12·3 breaths/minute, mean Vt  = 638·6 mls, mean inflation time = 1·3 seconds and peak airway pressure exceeded 40 cm H2 O in 41% of breaths, although only in 10% of breaths during the 'normal' lung scenario. CONCLUSIONS: Experienced nurses were able to manually hyperinflate 'normal' patients in a simulated setting safely. Despite their knowledge of barotrauma, unsafe airway pressures were delivered in some scenarios. RELEVANCE TO CLINICAL PRACTICE: Training with regard to safe airway pressures, breath hold and adequate volumes is recommended for all nurses undertaking the procedure. Nurses and physiotherapists must closely monitor the patient's condition during manual hyperinflation thereby recognising changes with regard to lung compliance and airway resistance, with nurses responding by altering their technique. The addition of a pressure manometer in the circuit may improve patient safety when performing manual hyperinflation.

Measuring height in recumbent critical care patients.

BACKGROUND: Estimates of the height of patients in the intensive care unit are required to adhere to clinical guidelines for drug dosages, ventilatory support, and nutrition. The gold standard of standing height cannot be used because these patients are often unconscious and recumbent. The ability of physiotherapists or dietitians to measure height in unconscious, recumbent patients has not been evaluated. OBJECTIVES: To compare the accuracy of physicians, physiotherapists, and dietitians in estimating the height of recumbent critical care patients by using existing practice methods. METHODS: A total of 35 patients were recruited from the cardiothoracic preadmission clinic, where standing height is routinely measured by a physiotherapist. After surgery, in the intensive care unit, 1 physician, 2 physiotherapists, and 2 dietitians measured each recumbent patient's height. Three methods were used: observation, whole-body measurement, and height estimated by using length of the forearm and the British Association for Parenteral and Enteral Nutrition normative chart. Difference from standing height was measured from zero and was compared across professions and methods, with zero indicating no difference. RESULTS: Overall, 17 physicians, 4 dietitians, and 9 physiotherapists consented to measure patients. After adjustments for method, measurements by physiotherapists did not differ significantly from the gold standard (P = .59), whereas those of physicians (P = .02) and dietitians (P < .001) did. CONCLUSIONS: Physiotherapists' measurements of supine height of recumbent critical care patients, obtained by using a nonrigid measuring tape, are more accurate than measurements obtained by physicians and dietitians.

Relationships between mortality, morbidity, and physical function in adults who survived a period of prolonged mechanical ventilation.

PURPOSE: This study aimed to report mortality, morbidity, and the relationship between these outcomes with physical function in patients who survived prolonged mechanical ventilation during an intensive care unit (ICU) admission. METHODS AND MATERIALS: Records were reviewed for Western Australian residents admitted to an ICU in 2007 or 2008 who were ventilated for 7 days or longer and survived their acute care stay. Records were linked with data maintained by the Department of Health. RESULTS: A total of 181 patients (aged 52 ± 19 years) were included in this study. In the 12 months after discharge, 159 (88%) survived and 148 (82%) had been hospitalized. Compared with those who were ambulating independently when discharged from acute care, those who were not had more admissions (incident rate ratio, 1.81; 95% confidence interval, 1.28-2.57) and a greater cumulative length of hospital stay (10 [37] vs 57 [115] days, P < .001) over the first 12 months after discharge. Time between admission to ICU and when the patient first stood correlated with the number of admissions (Rs = 0.320, P < .001) and cumulative length of stay (Rs = 0.426, P < .001) in the 12 months after discharge. CONCLUSIONS: For survivors of prolonged mechanical ventilation, physical function during acute care was associated with hospitalization over the following 12 months.

Guillain-Barré syndrome patient's satisfaction with physiotherapy: A two-part observational study.

The purpose of this observational study was to assess Guillain-Barre´ syndrome (GBS) patients' satisfaction with physiotherapy in the acute and sub-acute setting, and provide an overview of inpatient case management, including the number of complications. Twenty-seven patients admitted to Sir Charles Gairdner Hospital (SCGH) with GBS between 1 May 2005 and 30 April 2010 were considered for inclusion. Nineteen patients consented and a waiver of consent was granted for four other patients. Data were collected from case-note audit (n = 23) and telephone survey (n = 19) during June and July 2011. Participants receiving physiotherapy (n = 16) reported they were satisfied with management (87%), treatment frequency (88%), duration (94%), and timetabling (81%) of treatment and the professionalism and rapport (100%) of physiotherapists. Median length of hospital stay was 20 days (range 5-198) for 23 participants. Physiotherapists documented patient assessment within 2 days from admission (range 1-5). First functional improvements were documented on day 6 (median, range 2-34). Physiotherapists were most commonly first to mobilize patients to sit, stand, transfer, and walk (83%, 82%, 81%, and 90%, respectively). Twenty patients (87%) developed complications during their hospital stay, the most common being low back pain (61%). This study has demonstrated that GBS patients were satisfied with care provided by physiotherapy.

Exploring the capacity to ambulate after a period of prolonged mechanical ventilation.

PURPOSE: The purposes were to assess the functional recovery of those who survived a prolonged intensive care unit (ICU) stay by reporting the proportion who were able to ambulate independently at hospital discharge and also to examine if the time duration between admission and when the patient first stood impacted on their capacity to ambulate at discharge. MATERIALS AND METHODS: A retrospective review was conducted of medical records of ICU patients in 2007 to 2008, who were mechanically ventilated for 168 hours or more, and survived their acute care stay. Main outcome measures were (1) ambulation status before admission and at time of hospital discharge and (2) time between admission to the ICU and when the patient first stood. RESULTS: A total of 190 patients were included. Before admission, 189 (99%; 95% confidence interval [CI], 98%-100%) were ambulating independently, of whom 180 (95%) did not require a gait aid. On discharge from acute care, 89 (47%; 95% CI, 40%-54%) were ambulating independently, of whom 54 (61%) did not require a gait aid. Compared with those who stood within 30 days of ICU admission, a delay in standing of between 30 and 60 days increased the odds 5-fold (95% CI, 2-11) of being unable to ambulate independently at the time of discharge. CONCLUSIONS: After a prolonged ICU admission, more than 50% of patients were unable to ambulate independently by hospital discharge, with the time between admission and first stand, being an important predictor of this outcome.

Ventilator versus manual hyperinflation in clearing sputum in ventilated intensive care unit patients.

The aim of hyperinflation in the ventilated intensive care unit patient is to increase oxygenation, reverse lung collapse and clear sputum. The efficacy and consistency of manual hyperventilation is well supported in the literature, but there is limited published evidence supporting hyperventilation utilising a ventilator. Despite this, a recent survey established that almost 40% of Australian tertiary intensive care units utilise ventilator hyperinflation. The aim of this non-inferiority cross-over study was to determine whether ventilator hyperinflation was as effective as manual hyperinflation in clearing sputum from patients receiving mechanical ventilation using a prescriptive ventilator hyperinflation protocol. Forty-six patients received two randomly ordered physiotherapy treatments on the same day by the same physiotherapist. The efficacy of the hyperinflation modes was measured by sputum wet weight. Secondary measures included compliance, tidal volume, airway pressure and PaO2/FiO2 ratio. There was no difference in wet weight of sputum cleared using ventilator hyperinflation or manual hyperinflation (mean 3.2 g, P=0.989). Further, no difference in compliance (P=0.823), tidal volume (P=0.219), heart rate (P=0.579), respiratory rate (P=0.929) or mean arterial pressure (P=0.593) was detected. A statistically significant difference was seen in mean airway pressure (P=0.002) between techniques. The effect of techniques on the PaO2/FiO2 response ratio was dependent on time (interaction P=0.024). Physiotherapy using ventilator hyperinflation cleared a comparable amount of sputum and was as safe as manual hyperinflation. This research describes a ventilator hyperinflation protocol that will serve as a platform for continued discussion, research and development of its application in ventilated patients.
