RESUMO

IMPORTANCE: This research trial contributes to the evidence for occupational therapy service delivery in intensive care settings. OBJECTIVE: To explore the feasibility of a trial to evaluate the impact of early enhanced occupational therapy on mechanically ventilated patients in intensive care. DESIGN: Single-site assessor-blinded randomized controlled feasibility trial. SETTING: Level 5 8-bed adult medical-surgical intensive care unit (ICU) at Logan Hospital, Brisbane, Australia. PARTICIPANTS: Participants were 30 mechanically ventilated patients randomly allocated to two groups. OUTCOMES AND MEASURES: We compared standard care with enhanced occupational therapy with outcomes measured at discharge from the ICU, hospital discharge, and 90 days post randomization. The primary outcome measure was the FIM®. Secondary outcomes included the Modified Barthel Index (MBI); Montreal Cognitive Assessment; grip strength, measured using a dynamometer; Hospital Anxiety and Depression Scale; and the 36-Item Short-Form Health Survey (Version 2). The intervention group received daily occupational therapy, including cognitive stimulation, upper limb retraining, and activities of daily living. Data were analyzed using independent groups t tests and effect sizes. RESULTS: Measures and procedures were feasible. A significant difference was found between groups on FIM Motor score at 90 days with a large effect size (p = .05, d = 0.76), and MBI scores for the intervention group approached significance (p = .051) with a large effect size (d = 0.75) at 90 days. Further moderate to large effect sizes were obtained for the intervention group for cognitive status, functional ability, and quality of life. CONCLUSIONS AND RELEVANCE: This trial demonstrated that occupational therapy is feasible and beneficial in the ICU. Criteria to progress to a full-scale randomized controlled trial were met. This study contributes to embedding ongoing consistency of practice and scope of service delivery for occupational therapy in this field. What This Article Adds: Occupational therapists should be considered core team members in the critical care-ICU, with funding to support ongoing service provision and optimization of patient outcomes based on effective and feasible service delivery.

RESUMO

BACKGROUND: Pressure injuries (PIs) are an enduring problem for patients in the intensive care unit (ICU) because of their vulnerability and numerous risk factors. METHOD: This study reports Australian data as a subset of data from an international 1-day point prevalence study of ICU-acquired PI in adult patients. Patients aged 18 years or older and admitted to the ICU on the study day were included. The outcome measure was the identification of a PI by direct visual skin assessment on the study day. Data collected included demographic data and clinical risk factors, PI location and stage, and PI prevention strategies used. Descriptive statistics were used to describe PI characteristics, and odds ratios (ORs) were used to identify factors associated with the development of a PI. RESULTS: Data were collected from 288 patients from 16 Australian ICUs. ICU-acquired PI prevalence was 9.7%, with 40 PIs identified on 28 patients. Most PIs were of stage 1 and stage 2 (26/40, 65.0%). Half of the ICU-acquired PIs were found on the head and face. The odds of developing an ICU-acquired PI increased significantly with renal replacement therapy (OR: 4.25, 95% confidence interval [CI]: 1.49-12.11), impaired mobility (OR: 3.13, 95% CI: 1.08-9.12), fastest respiratory rate (OR: 1.05 [per breath per minute], 95% CI: 1.00-1.10), longer stay in the ICU (OR: 1.04 [per day], 95% CI: 1.01-1.06), and mechanical ventilation on admission (OR: 0.36, CI: 0.14-0.91). CONCLUSION: This study found that Australian ICU-acquired PI prevalence was 9.7% and these PIs were associated with many risk factors. Targeted PI prevention strategies should be incorporated into routine prevention approaches to reduce the burden of PIs in the Australian adult ICU patient population.

RESUMO

OBJECTIVES: The aim of this review is to appraise current research which examines the impact of early rehabilitation practices on functional outcomes and quality of life in adult intensive care unit (ICU) survivors. REVIEW METHOD USED: A systematic literature search was undertaken; retrieved data was evaluated against a recognised evaluation tool; research findings were analysed and categorised into themes; and a synthesis of conclusions from each theme was presented as an integrated summation of the topic. DATA SOURCES: Electronic databases of PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Ovid Medline and Google Scholar were searched using key search terms 'ICU acquired weakness', 'early rehabilitation' 'early mobility' and 'functional outcomes' combined with 'intensive care' and 'critical illness'. Additional literature was sourced from reference lists of relevant original publications. RESULTS: Five major themes related to the review objectives emerged from the analysis. These themes included: critically ill patients do not always receive physical therapy as a standard of care; ICU culture and resources determine early rehabilitation success; successful respiratory and physical rehabilitation interventions are tailored according to individual patient impairment; early exercise in the ICU prevents the neuromuscular complications of critical illness and improves functional status; early exercise in the ICU is effective, safe and feasible. CONCLUSIONS: A limited body of research supports early rehabilitation interventions to optimise the short term outcomes and long term quality of life for ICU survivors. Critical care nurses are in an excellent position to drive change within their departments ensuring that early rehabilitation practices are adopted and implemented.

RESUMO

BACKGROUND: The effect of the ABCDEF bundle (Assess, prevent, and manage pain; Both spontaneous awakening and spontaneous breathing trials; Choice of analgesia and sedation; Delirium: assess, prevent, and manage; Early mobility and exercise; and Family engagement and empowerment) on patient outcomes such as delirium is potentially optimised when the bundle is implemented in its entirety. OBJECTIVE: To systematically synthesise the evidence on the effectiveness of the ABCDEF bundle delivered in its entirety on delirium, function, and quality of life in adult intensive care unit patients. DESIGN: Systematic review and meta-analysis. DATA SOURCE: Electronic databases including MEDLINE, CINAHL, PsycINFO, Web of Science, Cochrane Library, Joanna Briggs Institute's Evidence Based Practice, Australian New Zealand Clinical Trials Registry, and Embase were searched from 2000 until December 2021. REVIEW METHODS: Inclusion criteria included (1) adult intensive care unit patients (2) studies that described the ABCDE or ABCDEF bundle in its entirety (3) studies that evaluated delirium, functional outcomes, or quality of life. Studies were excluded if they investigated long-term intensive care unit rehabilitation patients. Two reviewers independently screened records and full text, extracted data, and undertook quality appraisals with discrepancies discussed until consensus was reached. Random effects meta-analyses were conducted for delirium but was not possible for other outcomes. The Grading of Recommendations, Assessment, Development and Evaluation approach was used to assess the certainty of the synthesised findings of the body of evidence. The study protocol was registered on PROSPERO (CRD 42019126407). RESULTS: A total of 18 studies (29,576 patients) were included in the descriptive synthesis. Meta-analysis of six studies (2000 patients) identified decreased delirium incidence following implementation of the ABCDEF bundle when compared with standard practice, (risk ratio = 0.57; CI, 0.36-0.90 p = 0.02) although heterogeneity was high (I2 = 92%). When compared with standard practice, a meta-analysis of five studies (3418 patients) showed the ABCDEF bundle statistically significantly reduced the duration of intensive care unit delirium (mean difference (days) - 1.37, 95% CI -2.61 to -0.13 p = 0.03; I2 96%). Valid functional assessments were included in two studies, and quality of life assessment in one. CONCLUSIONS: Although the evidence on the effect of the ABCDEF bundle delivered in its entirety is limited, positive patient delirium outcomes have been shown in this meta-analysis. As this meta-analysis was based on only 4736 patients in eight studies, further evidence is required to support its use in the adult intensive care unit. REGISTRATION DETAILS: PROSPERO (CRD 42019126407).

RESUMO

INTRODUCTION: Hospital mortality for critically ill patients has decreased significantly throughout the developed world over the past two decades, attributable to improvements in the quality of intensive care, advances in critical care medicine and technologies that provide long-term multiorgan support. However, the long-term outcomes of intensive care unit (ICU) survivors is emerging as a real issue. Cognitive and physical impairments suffered by ICU survivors are common including profound weakness, pain and delirium which are inextricably linked. This study aims to determine the effectiveness of the Assess, prevent and manage pain; Both spontaneous awakening and spontaneous breathing trials; Choice of sedation and analgesia; Delirium: assess, prevent and manage; Early mobility and exercise; Family engagement and empowerment (ABCDEF) bundle in reducing ICU-related short-term and long-term consequences of critical illness through a randomised controlled trial (RCT). METHODS AND ANALYSIS: The study will be a single-centre, prospective RCT. A total of 150 participants will be recruited and randomised to either receive the ABCDEF bundle protocol or non-protocolised standard care for the duration of the participant's admission in the ICU. The primary outcome is delirium status measured using the Confusion Assessment Measure for ICU (CAM-ICU). Secondary outcomes include physical function measured by the Functional Independence Measure and quality of life measured by the European Quality of Life five dimensions, five-level questionnaire. A mixed-method process evaluation will contribute to understanding the experience of health teams who implement the ABCDEF bundle into practice. ETHICS AND DISSEMINATION: Ethics approval was provided by the Metro South Health Human Research Ethics Committee (HREC) (EC00167) and the Griffith University's HREC prior to study commencement.Study results will be disseminated by presentations at conferences and via publications to peer-review journals. TRIAL REGISTRATION NUMBER: ACTRN12620000736943; Pre-results.

RESUMO

BACKGROUND: Admissions to intensive care units (ICUs) are increasing due to an ageing population, and rising incidence of cardiac and respiratory disease. With advances in medical care, more patients are surviving an initial stay in critical care; however, they can experience ongoing health and cognitive limitations that may influence return to baseline function up to a year post-admission. Recent research has focused on the introduction of early rehabilitation within the ICU to reduce long-term physical and cognitive complications. The aim of this study is to explore the feasibility and impact of providing early enhanced occupation-based therapy, including cognitive stimulation and activities of daily living, to patients in intensive care. METHODS: This study involves a single site randomised-controlled feasibility trial comparing standard occupational therapy care to an early enhanced occupation-based therapy. Thirty mechanically ventilated ICU patients will be recruited and randomly allocated to the intervention or control group. The primary outcome measure is the Functional Independence Measure (FIM), and secondary measures include the Modified Barthel Index (MBI), Montreal Cognitive Assessment (MoCA), grip strength, Hospital Anxiety and Depression Scale (HADS) and Short-Form 36 Health survey (SF-36). Measures will be collected by a blind assessor at discharge from intensive care, hospital discharge and a 90-day follow-up. Daily outcome measures including the Glasgow Coma Scale (GCS), Richmond Agitation and Sedation Scale (RASS) and Confusion Assessment Measure for intensive care units (CAM-ICU) will be taken prior to treatment. Participants in the intervention group will receive daily a maximum of up to 60-min sessions with an occupational therapist involving cognitive and functional activities such as self-care and grooming. At the follow-up, intervention group participants will be interviewed to gain user perspectives of the intervention. Feasibility data including recruitment and retention rates will be summarised descriptively. Parametric tests will compare outcomes between groups. Interview data will be thematically analysed. DISCUSSION: This trial will provide information about the feasibility of investigating how occupational therapy interventions in ICU influence longer term outcomes. It seeks to inform the design of a phase III multicentre trial of occupational therapy in critical care general medical intensive care units.

RESUMO

INTRODUCTION: To compare outcomes from early post-pyloric to gastric feeding in ventilated, critically ill patients in a medical intensive care unit (ICU). METHODS: Prospective randomized study. Ventilated patients were randomly assigned to receive enteral feed via a nasogastric or a post-pyloric tube. Post-pyloric tubes were inserted by the bedside nurse and placement was confirmed radiographically. RESULTS: A total of 104 patients were enrolled, 54 in the gastric group and 50 in the post-pyloric group. Bedside post-pyloric tube insertion was successful in 80% of patients. Patients who failed post-pyloric insertion were fed via the nasogastric route, but were analysed on an intent-to treat basis. A per protocol analysis was also performed. Baseline characteristics were similar for all except Acute Physiology and Chronic Health Evaluation II (APACHE II) score, which was higher in the post-pyloric group. There was no difference in length of stay or ventilator days. The gastric group was quicker to initiate feed 4.3 hours (2.9 - 6.5 hours) as compared to post-pyloric group 6.6 hours (4.5 - 13.0 hours) (P = 0.0002). The time to reach target feeds from admission was also faster in gastric group: 8.7 hours (7.6 - 13.0 hours) compared to 12.3 hours (8.9 - 17.5 hours). The average daily energy and protein deficit were lower in gastric group 73 Kcal (2 - 288 Kcal) and 3.5 g (0 - 15 g) compared to 167 Kcal (70 - 411 Kcal) and 6.5 g (2.8 - 17.3 g) respectively but was only statistically significant for the average energy deficit (P = 0.035). This difference disappeared in the per protocol analysis. Complication rates were similar. CONCLUSIONS: Early post-pyloric feeding offers no advantage over early gastric feeding in terms of overall nutrition received and complications CLINICAL TRIAL: anzctr.org.au:ACTRN12606000367549.

RESUMO

BACKGROUND: External, independent accreditation assessments of healthcare organisations are necessary to ensure the nationally legislated minimum standards of quality and safety (QS) are met. The predetermined scheduling of the assessments continues to be criticised due to the high level of organisational emphasis on preparing for accreditation. OBJECTIVES: To determine the stakeholder perception of assessment thoroughness, staff resource requirements and workforce engagement changes if only 48 hours' notice is given to an organisation prior to an accreditation assessment, compared with the standard-notice accreditation process. METHODS: Logan and Beaudesert Hospitals in Brisbane, Australia, trialled the 'Short-Notice Survey Accreditation Assessment Process' (SNAAP) between August 2017 and December 2018. The organisation was given just 48 hours' notice prior to an accreditation assessment. Staff perception of the standard-notice accreditation process and short-notice process was assessed using a 5-point Likert scale repeated measures questionnaire (pretrial, 6 and 12 months after SNAAP launch). RESULTS: There was a statistically significant stakeholder opinion that SNAAP more effectively identified the true strengths and achievements of the organisation's QS compared with 'standard-notice' survey (p=0.033). There was a significantly lower overall perceived proportion of staff resources required for SNAAP preparation in contrast to 'standard-notice' process (Baseline Av=21.38% vs Follow-up 1 and 2 Av=9.75%-6.25%, p=0.021). The questionnaire results reflected that SNAAP increased staff engagement in QS activities (Av=3.75 and 3.69, 95% CI=3.45-4.05 and 3.45-3.94). CONCLUSIONS: With sufficient cultural and operational preparation to move to SNAAP, hospitals can potentially use SNAAP as a truer validation of QS standards, require less staffing resources to prepare for accreditation assessments and improve staff engagement in QS assurance and improvement.

RESUMO

BACKGROUND: Early rehabilitation has been found to prevent delirium and weakness that can hamper the recovery of intensive care unit (ICU) survivors. Integrated clinical practice guidelines for managing patient pain, agitation and delirium (PAD) have been developed. The Awakening and Breathing Coordination, Delirium monitoring/management, and Early exercise/mobility (ABCDE) bundle provides a strategy to implement PAD guidelines into everyday clinical practice. However, there is limited evidence on the effectiveness of the ABCDE bundle in the literature.The purpose of this study was to evaluate the feasibility of conducting a full-scale randomised controlled trial comparing the ABCDE bundle to standard care in an ICU. Trial feasibility was defined as the successful recruitment and retention of trial participants, adherence to the intervention, identification of barriers to the intervention, and the rigorous collection of outcome data. METHODS: A prospective, single-centre, randomised controlled feasibility study was conducted. Thirty adult mechanically ventilated participants were recruited from an eight-bed ICU in south east Queensland, Australia, between April 2015 and December 2015. Participants were randomised to receive either the ABCDE bundle or standard routine management. The ABCDE bundle integrated prescribed awakening and breathing trials, delirium monitoring and management, and prescribed exercise and mobility regimes. Feasibility outcomes measured included recruitment and retention rates, intervention fidelity, and the feasibility of participant outcome data collection. Outcome measurement assessors were blinded to participant assignment. It was not possible to blind the research team or the participant to group assignment. RESULTS: In total, 30 (81.1%) of 37 eligible participants consented and were randomised to the intervention group (n = 15) or the control group (n = 15). Of these, 23 (76.6%) participants successfully completed the 90-day post discharge assessment. A lengthy recruitment period of 8 months was related to overly stringent inclusion and exclusion criteria. Intervention adherence exceeded defined success rates with participation in awakening and breathing trials, delirium monitoring and exercise interventions performed on 80.2, 97.4 and 90.2% of ventilated days respectively. Outcome assessments were successfully and accurately performed at ICU and hospital discharge and 90-day post hospital discharge. Intervention participants were deemed to be delirious on 39.6% of mechanically ventilated days indicating a requirement for a scripted regime to prevent delirium. CONCLUSIONS: With minor adjustment of inclusion and exclusion criteria, the inclusion of delirium management protocols, and encouragement of family engagement and involvement, a large-scale definitive randomised controlled trial to test the impact of the ABCDEF bundle will be feasible.

RESUMO

Thrombosis is a complication of many chronic illnesses. Chronic obstructive pulmonary disease (COPD) and diabetes mellitus are common medical conditions frequently associated with a hypercoagulable state. Acidaemia has been shown to reduce coagulation. COPD and diabetes mellitus during acute deterioration can present with a severe acidaemia. The impact of this acidaemia on coagulation is poorly studied. Patients presenting with a diagnosis of diabetic ketoacidosis or type II respiratory failure from COPD and a pH of less than 7.2 were included in our study. A coagulation screen and a thromboelastograph (TEG) were performed on admission and 24 hours later. The mean pH on admission was 7.07 and mean base excess was -16.3. The activated partial thromboplastin time was associated with pH change but remained within the normal range (26-41 s). All other coagulation and TEG parameters failed to show evidence of association (p>0.05). In the two models of non-haemorrhagic acidosis investigated, coagulation was not altered by the changes in pH. More work is needed to understand the complex relationship between factors affecting coagulation in individual disease processes.

RESUMO

BACKGROUND & AIM: Nutritional intake of patients in acute respiratory failure receiving non-invasive ventilation has not previously been described, and no protocols have been developed to guide practice to optimise nutritional status. We aimed to measure energy and protein intakes of patients in acute respiratory failure requiring non-invasive ventilation receiving standard hospital nutritional care. METHODS: Food and fluid intake forms were completed by nursing staff for all meals and mid meals for patients admitted with respiratory failure commencing on non-invasive ventilation. Intake was converted from quartiles of food consumed into energy and protein to enable comparison with estimated daily requirements using descriptive statistics. Multinomial stepwise regression analysis was used to determine factors associated with inadequate protein and energy intake. RESULTS: Over 283 total days of intake, 36 participants (67% female, aged 65 ± 9 years) achieved on average 1434 ± 627 kcal and 63 ± 29 g protein daily. Overall, 28 patients (78%, 95% CI: 61-90%) met less than 80% of estimated energy requirements and 27 patients (75%, 95% CI: 58-88%) met less than 80% of estimated protein requirements. Being fed orally, longer time on non-invasive ventilation and higher BMI were associated with poorer intakes. Better nutritional status on admission and measuring intake closer to hospital discharge was associated with improved intakes. CONCLUSION: Patients with acute respiratory failure requiring non-invasive ventilation often had inadequate oral intake, particularly with increasing time on non-invasive ventilation, and earlier during their hospital admission. Development of protocols to optimise nutritional intake for these patients may improve outcomes and reduce regular readmission rates.

RESUMO

Low molecular weight heparins (LMWHs) are used for prevention and management of vascular thrombosis. In general, monitoring of anticoagulant activity is not required, however, certain populations may be susceptible to overdosing or underdosing. As anti-activated factor X(anti-Xa) activity testing is not readily available, it was our aim to investigate the usefulness of thromboelastography (TEG; Haemoscope Corporation, Skokie, Illinois, USA) for the assessment of coagulation in patients on LMWH. All patients admitted to the coronary care unit on therapeutic dose of enoxaparin were included (1 mg/kg twice daily). Blood samples were collected 4 h after the morning dose of enoxaparin once the participant had received at least three doses. When anti-Xa activity was classified as low (0-0.5), correct (0.5-1.0) or high (>1.0), the distribution of reaction time (R) and dose per kg showed little association with anti-Xa activity. The difference between mean R for the high anti-Xa group and the correct anti-Xa group was statistically nonsignificant using two-sample t-test (P = 0.26). A linear regression model showed no evidence of association between dose per kg and anti-Xa (P = 0.95). However, there was evidence of positive association between dose per kg and R (P = 0.011) wherein a 10% increase in dose per kg was associated with an increase in R of 2.7 (95% confidence interval 0.6-4.7). There was no evidence of association between R and anti-Xa (P = 0.38). TEG was unable to be used to predict anti-Xa activity. However, TEG R was prolonged in more than 90% patients and correlated with dose of enoxaparin. As enoxaparin dose correlated poorly with anti-Xa activity, a more global test might be necessary to adjust dosing of LMWH in sick, hospitalized patients.
