'How Do I Test the Waters? How Do I Go Forward?': Co-designing a Supportive Pathway after Critical Illness

Rationale: Long-term recovery following critical illness can be affected by Post-intensive Care Syndrome (PICS), a significant burden which can impact return to activities and work. There is need for streamlined support for Intensive Care Unit (ICU) patients in their recovery whilst enduring PICS symptoms. Objectives: To explore critical illness recovery from the experiences, perspectives, and beliefs of former ICU patients, their caregivers, and multidisciplinary clinicians to design a future rehabilitation pathway to support ICU patients. Methods: An experience-based co-design (EBCD) study underpinned by the Behaviour Change Wheel (BCW) framework involving ICU patients ( Collapse

Potential role for extracorporeal membrane oxygenation cardiopulmonary resuscitation (E-CPR) during in-hospital cardiac arrest in Australia: A nested cohort study

Objective

This study aims to evaluate the characteristics and outcomes of patients who fulfilled extracorporeal membrane oxygenation cardiopulmonary resuscitation (E-CPR) selection criteria during in-hospital cardiac arrest (IHCA).

Design

This is a nested cohort study.

Setting

Code blue data were collected across seven hospitals in Australia between July 2017 and August 2018.

Participants

Participants who fulfilled E-CPR selection criteria during IHCA were included.

Main outcome measures

Return of spontaneous circulation and survival and functional outcome at hospital discharge. Functional outcome was measured using the modified Rankin scale, with scores dichotomised into good and poor functional outcome.

Results

Twenty-three (23/144; 16%) patients fulfilled E-CPR selection criteria during IHCA, and 11/23 (47.8%) had a poor outcome. Patients with a poor outcome were more likely to have a non-shockable rhythm (81.8% vs. 16.7%; p = 0.002), and a longer duration of CPR (median 12.5 [5.5, 39.5] vs. 1.5 [0.3, 2.5] minutes; p < 0.001) compared to those with a good outcome. The majority of patients (18/19 [94.7%]) achieved sustained return of spontaneous circulation within 15 minutes of CPR. All five patients who had CPR >15 minutes had a poor outcome.

Conclusion

Approximately one in six IHCA patients fulfilled E-CPR selection criteria during IHCA, half of whom had a poor outcome. Non-shockable rhythm and longer duration of CPR were associated with poor outcome. Patients who had CPR for >15 minutes and a poor outcome may have benefited from E-CPR. The feasibility, effectiveness and risks of commencing E-CPR earlier in IHCA and among those with non-shockable rhythms requires further investigation.

Comparison of 6-Month Outcomes of Survivors of COVID-19 versus Non-COVID-19 Critical Illness

Rationale: The outcomes of survivors of critical illness due to coronavirus disease (COVID-19) compared with non-COVID-19 are yet to be established. Objectives: We aimed to investigate new disability at 6 months in mechanically ventilated patients admitted to Australian ICUs with COVID-19 compared with non-COVID-19. Methods: We included critically ill patients with COVID-19 and non-COVID-19 from two prospective observational studies. Patients were eligible if they were adult (age ⩾ 8 yr) and received ⩾24 hours of mechanical ventilation. In addition, patients with COVID-19 were eligible with a positive laboratory PCR test for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Measurements and Main Results: Demographic, intervention, and hospital outcome data were obtained from electronic medical records. Survivors were contacted by telephone for functional outcomes with trained outcome assessors using the World Health Organization Disability Assessment Schedule 2.0. Between March 6, 2020, and April 21, 2021, 120 critically ill patients with COVID-19, and between August 2017 and January 2019, 199 critically ill patients without COVID-19, fulfilled the inclusion criteria. Patients with COVID-19 were older (median [interquartile range], 62 [55-71] vs. 58 [44-69] yr; P = 0.019) with a lower Acute Physiology and Chronic Health Evaluation II score (17 [13-20] vs. 19 [15-23]; P = 0.011). Although duration of ventilation was longer in patients with COVID-19 than in those without COVID-19 (12 [5-19] vs. 4.8 [2.3-8.8] d; P < 0.001), 180-day mortality was similar between the groups (39/120 [32.5%] vs. 70/199 [35.2%]; P = 0.715). The incidence of death or new disability at 180 days was similar (58/93 [62.4%] vs. 99/150 [66/0%]; P = 0.583). Conclusions: At 6 months, there was no difference in new disability for patients requiring mechanical ventilation for acute respiratory failure due to COVID-19 compared with non-COVID-19.

Physiotherapy-assisted prone or modified prone positioning in ward-based patients with COVID-19: a retrospective cohort study

Objectives

To evaluate short-term change in oxygenation and feasibility of physiotherapy-assisted prone or modified prone positioning in awake, ward-based patients with COVID-19.

Design

Retrospective observational cohort study.

Setting

General wards, single-centre tertiary hospital in Australia.

Participants

Patients were included if ≥18 years, had COVID-19, required FiO₂ ≥ 0.28 or oxygen flow rate ≥4 l/minute and consented to positioning. Main outcome measures: Feasibility measures included barriers to therapy, assistance required, and comfort. Short-term change in oxygenation (SpO₂) and oxygen requirements before and 15 minutes after positioning.

Results

Thirteen patients, mean age 75 (SD 14) years; median Clinical Frailty Scale score 6 (IQR 4 to 7) participated in 32 sessions of prone or modified prone positioning from a total of 125 ward-based patients admitted with COVID-19 who received physiotherapy intervention. Nine of thirteen patients (69%) required physiotherapy assistance and modified positions were utilised in 8/13 (62%). SpO2 increased in 27/32 sessions, with a mean increase from 90% (SD 5) pre-positioning to 94% (SD 4) (mean difference 4%; 95%CI 3 to 5%) after 15 minutes. Oxygen requirement decreased in 14/32 sessions, with a mean pre-positioning requirement of 8 l/minute (SD 4) to 7 l/minute (SD 4) (mean difference 2 l/minute; 95%CI 1 to 3 l/minute) after 15 minutes. In three sessions oxygen desaturation and discomfort occurred but resolved immediately by returning supine.

Conclusion

Physiotherapy-assisted prone or modified prone positioning may be a feasible option leading to short-term improvements in oxygenation in awake, ward-based patients with hypoxemia due to COVID-19. Further research exploring longerterm health outcomes and safety is required.

The impact of COVID-19 critical illness on new disability, functional outcomes and return to work at 6 months: a prospective cohort study

BACKGROUND

There are few reports of new functional impairment following critical illness from COVID-19. We aimed to describe the incidence of death or new disability, functional impairment and changes in health-related quality of life of patients after COVID-19 critical illness at 6 months.

METHODS

In a nationally representative, multicenter, prospective cohort study of COVID-19 critical illness, we determined the prevalence of death or new disability at 6 months, the primary outcome. We measured mortality, new disability and return to work with changes in the World Health Organization Disability Assessment Schedule 2.0 12L (WHODAS) and health status with the EQ5D-5LTM.

RESULTS

Of 274 eligible patients, 212 were enrolled from 30 hospitals. The median age was 61 (51-70) years, and 124 (58.5%) patients were male. At 6 months, 43/160 (26.9%) patients died and 42/108 (38.9%) responding survivors reported new disability. Compared to pre-illness, the WHODAS percentage score worsened (mean difference (MD), 10.40% [95% CI 7.06-13.77]; p < 0.001). Thirteen (11.4%) survivors had not returned to work due to poor health. There was a decrease in the EQ-5D-5LTM utility score (MD, - 0.19 [- 0.28 to - 0.10]; p < 0.001). At 6 months, 82 of 115 (71.3%) patients reported persistent symptoms. The independent predictors of death or new disability were higher severity of illness and increased frailty.

CONCLUSIONS

At six months after COVID-19 critical illness, death and new disability was substantial. Over a third of survivors had new disability, which was widespread across all areas of functioning. Clinical trial registration NCT04401254 May 26, 2020.

The perceived barriers and facilitators to implementation of early mobilisation within a multicentre, phase 3 randomised controlled trial: A qualitative process evaluation study

BACKGROUND

Process evaluation within clinical trials provides an assessment of the study implementation's accuracy and quality to explain causal mechanisms and highlight contextual factors associated with variation in outcomes.

OBJECTIVES

This study aimed to identify the barriers and facilitators of implementing early mobilisation (EM) within a trial.

METHODS

This is a qualitative process evaluation study within the Trial of Early Activity and Mobilisation (TEAM) phase 3 randomised controlled trial. Semistructured interviews were conducted remotely with multiprofessional clinicians (physiotherapists, medical staff, and nursing staff) involved in the delivery of the TEAM intervention at Australian hospitals participating in the TEAM study. Inductive coding was used to establish themes which were categorised into the Behaviour system involving domains of Capability, Opportunity, and Motivation (COM-B), which allowed barriers and enablers affecting EM to be identified.

FINDINGS

Semistructured interviews were conducted in three different states of Australia. There were 16 participants, including 10 physiotherapists, five physicians, and one nurse. The key themes that facilitated EM were mentoring, champions, additional staff, organisation of the environment, cultural changes, communication, and documented safety criteria. In contrast, the main factors that hindered EM were lack of expertise and confidence in delivering EM, heavy sedation, interdisciplinary conflicts, and perceived risks related to EM.

CONCLUSION

A wide range of barriers and facilitators that influenced EM within the TEAM study were identified using the COM-B framework. Many of these have been previously identified in the literature; however, participation in the study was viewed positively by multidisciplinary team members.

Survival and functional outcome at hospital discharge following in-hospital cardiac arrest (IHCA): A prospective multicentre observational study

AIM

To evaluate the functional outcome of patients after in-hospital cardiac arrest (IHCA) and to identify associations with good functional outcome at hospital discharge.

METHOD

Emergency calls were prospectively screened and data collected for IHCAs in seven Australian hospitals. Patients were included if aged > 18 years, admitted as an acute care hospital in-patient and experienced IHCA; defined by a period of unresponsiveness with no observed respiratory effort and commencement of external cardiac compressions. Data collected included patient demographics, clinical and cardiac arrest characteristics, survival and functional outcome at hospital discharge using the modified Rankin Scale (mRS) and Katz Index of Independence in ADLs (Katz-ADL).

RESULTS

152 patients suffered 159 IHCAs (male 66.4%; mean age 70.2 (± 13.9) years). Sixty patients (39.5%) survived, of whom 43 (71.7%) had a good functional outcome (mRS ≤ 3) and 38 (63.3%) were independent with activities of daily living (ADLs) at hospital discharge (Katz-ADL = 6). Younger age (OR 0.95; 95% CI 0.91-0.98; p = 0.003), shorter duration of CPR (OR 0.84; 95% CI 0.77-0.91; p < 0.0001) and shorter duration of hospital admission prior to IHCA (OR 0.96; 95% CI 0.93-0.998; p = 0.04) were independently associated with a good functional outcome at hospital discharge.

CONCLUSION

The majority of survivors had a good functional outcome and were independent with their ADLs at hospital discharge. Factors associated with good functional outcome at hospital discharge were identified.

Inactivation of creatine kinase in physiological saline solutions

To determine the optimal conditions for measuring the activity of creatine kinase released from isolated skeletal muscle preparations, we investigated the stability of the enzyme during storage in saline solutions of varying composition. Parameters studied were temperature, presence of albumin or dithiothreitol, calcium concentration and anionic composition. It is concluded that maximal activity is retained when samples are kept at 4 degrees C and analyzed within 24 hours in the presence of a thiol-protective compound. If longer storage periods are anticipated, inactivation is significantly retarded by addition of albumin or by decreasing the free calcium concentration of the storage salines.
