A pilot feasibility randomised controlled trial of bone antiresorptive agents on bone turnover markers in critically ill women.

Critical illness is associated with increased bone turnover, loss of bone density, and increased risk of fragility fractures. The impact of bone antiresorptive agents in this population is not established. This trial examined the efficacy, feasibility, and safety of antiresorptive agents administered to critically ill women aged fifty years or greater. Women aged 50 years or greater admitted to an intensive care unit for at least 24 h were randomised to receive an antiresorptive agent (zoledronic acid or denosumab) or placebo, during critical illness and six months later (denosumab only). Bone turnover markers and bone mineral density (BMD) were monitored for 1 year. We studied 18 patients over 35 months before stopping the study due to the COVID-19 pandemic. Antiresorptive medications decreased the bone turnover marker type 1 cross-linked c-telopeptide (CTX) from day 0 to 28 by 43% (± 40%), compared to an increase of 26% (± 55%) observed with placebo (absolute difference - 69%, 95% CI - 127% to - 11%), p = 0.03). Mixed linear modelling revealed differences in the month after trial drug administration between the groups in serum CTX, alkaline phosphatase, parathyroid hormone, and phosphate. Change in BMD between antiresorptive and placebo groups was not statistically analysed due to small numbers. No serious adverse events were recorded. In critically ill women aged 50-years and over, antiresorptive agents suppressed bone resorption markers without serious adverse events. However, recruitment was slow. Further phase 2 trials examining the efficacy of these agents are warranted and should address barriers to enrolment.Trial registration: ACTRN12617000545369, registered 18th April 2017.

What are the care needs of families experiencing cardiac arrest?: A survivor and family led scoping review.

AIM: The sudden and unexpected cardiac arrest of a family member can be a grief-filled and life-altering event. Every year many hundreds of thousands of families experience the cardiac arrest of a family member. However, care of the family during the cardiac arrest and afteris poorly understood and incompletely described. This review has been performed with persons with lived experience of cardiac arrest to describe, "What are the needs of families experiencing cardiac arrest?" from the moment of collapse until the outcome is known. METHODS: This review was guided by specific methodological framework and reporting items (PRISMA-ScR) as well as best practices in patient and public involvement in research and reporting (GRIPP2). A search strategy was developed for eight online databases and a grey literature review. Two reviewers independently assessed all articles for inclusion and extracted relevant study information. RESULTS: We included 47 articles examining the experience and care needs of families experiencing cardiac arrest of a family member. Forty one articles were analysed as six represented duplicate data. Ten family care need themes were identified across five domains. The domains and themes transcended cardiac arrest setting, aetiology, family-member age and family composition. The five domains were i) focus on the family member in cardiac arrest, ii) collaboration of the resuscitation team and family, iii) consideration of family context, iv) family post-resuscitation needs, and v) dedicated policies and procedures. We propose a conceptual model of family centred cardiac arrest. CONCLUSION: Our review provides a comprehensive mapping and description of the experience of families and their care needs during the cardiac arrest of a family-member. Furthermore, our review was conducted with co-investigators and collaborators with lived experience of cardiac arrest (survivors and family members of survivors and non-survivors alike). The conceptual framework of family centred cardiac arrest care presented may aid resuscitation scientists and providers in adopting greater family centeredness to their work.

The Needs of Families During Cardiac Arrest Care: A Survivor- and Family-led Scoping Review Protocol.

INTRODUCTION: Sudden cardiac arrest is a leading cause of death. Family members often witness the event and attempt resuscitation. The physiological and psychological impact of a loved one's death, witnessed or unwitnessed, can be significant and long-lasting. However, little is known about the care needs of families during the cardiac arrest care of a loved one. This scoping review protocol was designed with, and will be performed in partnership with, persons with lived experience of sudden cardiac arrest (survivors and family members of survivors and nonsurvivors alike). METHODS: The review will be performed in accordance with accepted methods such as the Arksey and O'Malley methodology framework and the Levac extension. We will search multiple databases, and Google Scholar for both qualitative and quantitative scientific literature. Articles will be screened, extracted, and analyzed by a team with lived experience of cardiac arrest. Two reviewers will conduct all screening and data extraction independently. A descriptive overview, tabular and/or graphical summaries, and a directed content analysis will be carried out on extracted data. DISCUSSION: This protocol outlines a planned literature review to systematically examine the nature of existing evidence to describe what the care needs of families experiencing the cardiac arrest of a loved one are. Such evidence will contribute to the development of strategies to meet identified care needs. Persons with lived experience participated in the creation of this protocol, and they will also participate in the execution of this review as partners and coinvestigators, not as research subjects or participants. The results of the scoping review will be disseminated upon completion of the work described in this protocol.

Effect of communication skills training on outcomes in critically ill patients with life-limiting illness referred for intensive care management: a before-and-after study.

OBJECTIVES: To describe the effect of a communication skills training programme on patient-centred goals of care documentation and clinical outcomes in critically ill patients with life-limiting illnesses (LLI) referred for intensive care management. METHODS: Prospective before-and-after cohort study in a tertiary teaching hospital in Australia. The population was 222 adult patients with LLI referred to the intensive care unit (ICU). The study was divided into two periods, before (1 May to 31 July 2015) and after (15 September to 15December 2015) the intervention. The intervention was a 2-day, small group, simulated-patient, communication skills course, and process of care for patients with LLI. The primary outcome was documentation of patient-centred goals of care discussion (PCD) within 48 hours of referral to the ICU. Secondary outcomes included clinical outcomes and 90-day mortality. RESULTS: The intervention was associated with increased documentation of a PCD from 50% to 69% (p=0.004) and 43% to 94% (p<0.0001) in patients deceased by day 90. A significant decrease in critical care as the choice of resuscitation goal (61% vs 42%, p=0.02) was observed. Although there was no decrease in admission to ICU, there was a significant decrease in medical emergency team call prevalence (87% vs 73%, p=0.009). The cancer and organ failure groups had a significant decrease in 90-day mortality (75% vs 44%, p=0.02; 42% vs 16%, p=0.01), and the frailty group had a significant decrease in 90-day readmissions (48% vs 19%, p=0.003). CONCLUSIONS: The intervention was associated with increased PCD documentation and decrease in the choice of critical care as the resuscitation goal. Admissions to ICU did not decrease, and although limited by study design, condition-specific trajectory changes, clinical interventions and outcomes warrant further study.

Comparison of pulmonary artery catheter, echocardiography, and arterial waveform analysis monitoring in predicting the hemodynamic state during and after cardiac surgery.

OBJECTIVE: The aim of this trial was to determine whether Flotrac Vigileo™ (FV™) provides a reliable representation of the hemodynamic state of a cardiac surgical patient population when compared to pulmonary artery catheter (PAC) and echocardiography in the peril-operative period. DESIGN: This was a prospective observational trial comparing perioperative hemodynamic states using transesophageal echocardiography (TEE), transthoracic echocardiography (TTE), FV™ and PAC during and post cardiothoracic surgery. SETTING: Tertiary regional hospital Intensive Care Unit (ICU). PARTICIPANTS: 50 consecutive adult cardiothoracic patients with written consent provided. INTERVENTION: Comparison of the perioperative hemodynamic states using echocardiography, FV™ and PAC was performed. Evaluation of the hemodynamic state (HDS) was performed using TEE, TTE, PAC and FV™ during and after cardiac surgery. Data were compared between the three hemodynamic assessment modalities. MAIN OUTCOME MEASURE: Predicted hemodynamic state. RESULTS: FV™ and PAC were shown to correlate poorly with TEE/TTE assessment of the hemodynamic state. Both PAC and FV™ showed significant discordance with echocardiographic assessment of the hemodynamic state. CONCLUSIONS: In this trial, FV™ and PAC were shown to agree poorly with TTE/TEE assessment of the HDS in an adult cardiothoracic population. Agreement between the FV™ and PAC was also poor. Caution is recommended in interpreting isolated hemodynamic monitoring data. All hemodynamic monitoring devices have inherent sources of error. Caution is advised in interpreting any single device or measurement as a gold standard. We suggest that hemodynamic measuring devices such as FV™/PAC may act as triggers for a global hemodynamic assessment including consideration of TTE/TEE.

Prevalence, goals of care and long-term outcomes of patients with life-limiting illness referred to a tertiary ICU.

OBJECTIVE: To describe the prevalence, characteristics, long-term outcomes and goals-of-care discussions of patients with objective indicators of life-limiting illnesses (LLIs) referred to the intensive care unit. DESIGN, SETTING AND PATIENTS: A prospective, observational, cohort study of all adult inpatients referred to the ICU by the medical emergency team or by direct referral, during the period 30 August 2012 to 1 February 2013, at a tertiary teaching hospital in Australia. MAIN OUTCOME MEASURES: Mortality, LLIs, discharge destination and documentation on goals of care in medical record. RESULTS: A total of 649 of 1024 patients referred to the ICU had an LLI, and only 34.4% of these patients had goals of care documented. Overall, 49.2% were admitted to the ICU, 48.4% were discharged home, and the 1-year mortality was 35.1%. The most common LLI criteria were heart disease (52.2%), chronic obstructive pulmonary disease (24.8%) and frailty (23.7%). The highest 1-year mortality was associated with pre-hospital residence in a nursing home (64.9%), dementia (63.3%), cancer (60.8%) and frailty (50.6%). Analysis of patients by clinical trajectory showed that 1-year mortality was significantly higher for patients with cancer (59.6%), combined organ failure and frailty (47.3%), frailty (43.8%) and organ failure (23.6%), compared with patients with no LLI (P < 0.0001). CONCLUSIONS: A high proportion of patients referred to the ICU have an LLI, and this is associated with prolonged hospital length of stay and a high 1-year mortality, and only one-quarter have documented discussions on goals of care. Patients with cancer-related and frailty-related LLIs have the worst survival trajectories.
