The feasibility and acceptability of a physician-led ICU follow-up service: A prospective cohort study.

BACKGROUND: Increased recognition of post-intensive care syndrome has led to widespread development of intensive care follow-up services internationally. OBJECTIVE: The objective of this study was to determine the feasibility and acceptability of an intensive care unit (ICU) follow-up clinic in Australia for patients and their caregivers and to describe satisfaction with this service. METHODS: This was a prospective cohort study in a mixed tertiary ICU in Australia. Eligible patients were adults admitted to the ICU for 7 days or more and/or ventilated for 48 h or more, as well as their primary caregiver. Patients and their primary caregivers were invited to attend a follow-up clinic 4-8 weeks after hospital discharge. The clinic appointment was attended by an ICU physician and nurse, with multidisciplinary support. Feasibility and acceptability were defined as the proportion of clinic attendance and frequency of interventions initiated at the clinic. Satisfaction was measured by a 5-point satisfaction survey (very dissatisfied to very satisfied). The burden of ongoing disease was reported via multiple validated instruments. RESULTS: From April 2020-July 2021, 386 patients met the inclusion criteria. Only 146 patients were approached for consent due to site staffing limitations. Eighty-three patients and 32 caregivers consented to attend the clinic. Seventy percent (54/77) of patients attended scheduled appointments and 50% (16/32) of caregivers. For patients, 23 medical referrals were made, 8 patients had medication changes, and 10 patients were offered social work support. Satisfaction surveys were completed by 65% (35/54) of attending patients; 97% (34) patients reported either being 'very satisfied' or 'satisfied' with the service. All responding caregivers (10) were either 'very satisfied' or 'satisfied' with the clinic. CONCLUSION: There were a large number of patients meeting the inclusion criteria to the ICU follow-up clinic, and clinic attendance was moderate for patients but lower for caregivers. Reported satisfaction with the service was high for both patients and their caregiver.

Impact of hospitalisation on behavioural and physiological stress responses associated with cardiovascular risk in visiting family members.

BACKGROUND: The hospitalisation of a patient in intensive care impacts the psychological health of family members, with a high prevalence of anxiety, depression, and post-traumatic stress symptoms reported among families of critically ill patients. Understanding of the behavioural and physiological impact is limited and presents a new area of focus. OBJECTIVES: The objective of this study was to evaluate behavioural and physiological stress responses of visiting family members following hospitalisation of their adult relative. METHODS: Prospective longitudinal evaluation included 40 family members of adult patients with admission to intensive or coronary care in a large tertiary care metropolitan hospital. Assessments were conducted at three timepoints: in-hospital within 1 week of admission and 2 weeks and 3 months post discharge. Assessments included duration and quality of sleep (self-reported and actigraphy measured), physical activity, dietary and alcohol patterns, resting heart rate and blood pressure, and morning blood cortisol and lipid levels. Assessment of a reference group of 40 non-hospital-exposed control participants was also conducted. RESULTS: At the in-hospital assessment, study participants reported lower sleep time, altered 24-h physical activity patterns, reduced dietary and alcohol intake, and higher systolic and diastolic blood pressure than a nonhospitalised reference group. Compared to in-hospital assessment, these altered behavioural and physiological responses improved over time except for systolic blood pressures which remained unchanged at 3 months post family member discharge. CONCLUSION: Hospitalisation is associated with altered behavioural and physiological responses in family members. These findings contribute to understanding of the impact of unexpected hospitalisation on family members' cardiovascular risk factors and provide insights into potential mechanisms for the proposed increased risk during this time. Elevated systolic blood pressure at 3 months post discharge suggests a prolonged cardiovascular stress response in many family members of critical care patients that requires further study, with a focus on contributing and potential modifiable factors.

Psychological responses and coping behaviour of visiting family members during and following unplanned hospital admission.

AIMS: To describe the psychological symptoms and coping behaviours of visiting family members following the unplanned hospitalisation of their relative. BACKGROUND: Hospitalisation of a patient is recognised as a stressful time for visiting family members, who experience psychological morbidity and elevated health risk. DESIGN: This prospective longitudinal evaluation included 40 family members of patients with unplanned admission to coronary or intensive care. Assessments were conducted at 3 timepoints: in-hospital within 1 week of admission and again at 2 weeks and 3 months post-discharge. Measures included symptoms of anxiety, depression, and anger, coping strategies and social support. This paper adhered to STROBE guidelines. RESULTS: At the initial in-hospital assessment study participants reported higher anxiety, depression and anger symptoms levels compared to community matched control participants. Compared to in-hospital assessment, anxiety and depression levels were lower at 2 weeks and 3 months following hospital discharge. The use of active coping and the use of religion during early hospitalisation were associated with higher anxiety and depression symptoms at 3 months post-discharge. Conversely, use of instrumental support (getting help and advice from others), planning and venting during early hospitalisation were associated with lower depression symptoms at 3 months. Venting during the hospitalisation period was also associated with lower anxiety symptoms at 3 months. CONCLUSION: Results demonstrate the significant psychological impact of unplanned hospitalisation on visiting family members both during and following hospitalisation. The finding that prolonged psychological response is associated with individual coping strategies employed in the early hospitalised period informs potential preventative approaches for family members at risk of prolonged psychological morbidity following hospitalisation of their loved one. RELEVANCE TO CLINICAL PRACTICE: The reported psychological impact of hospitalisation on family members provides a strong imperative for nurses and health professionals to provide early individualised support to reduce the risk of long-term psychological morbidity.

The effect of metoprolol and aspirin on cardiovascular risk in bereavement: A randomized controlled trial.

BACKGROUND: Bereavement is associated with an increased risk of cardiovascular disease; however, no reports exist of interventions to reduce risk. In a randomized, double-blind, placebo-controlled trial of 85 recently bereaved participants, we determined whether ß-blocker (metoprolol 25 mg) and aspirin (100 mg) reduce cardiovascular risk markers and anxiety, without adversely affecting bereavement intensity. METHODS: Participants were spouses (n = 73) or parents (n = 12) of deceased from 5 hospitals in Sydney, Australia, 55 females, 30 males, aged 66.1 ±â€¯9.4 years. After assessment within 2 weeks of bereavement, subjects were randomized to 6 weeks of daily treatment or placebo, and the effect evaluated using ANCOVA, adjusted for baseline values (primary analysis). RESULTS: Participants on metoprolol and aspirin had lower levels of home systolic pressure (P = .03), 24-hour average heart rate (P < .001) and anxiety (P = .01) platelet response to arachidonic acid (P < .001) and depression symptoms (P = .046) than placebo with no difference in standard deviation of NN intervals index (SDNNi), von Willebrand Factor antigen, platelet-granulocyte aggregates or bereavement intensity. No significant adverse safety impact was observed. CONCLUSIONS: In early bereavement, low dose metoprolol and aspirin for 6 weeks reduces physiological and psychological surrogate measures of cardiovascular risk. Although further research is needed, results suggest a potential preventive benefit of this approach during heightened cardiovascular risk associated with early bereavement.

IL-1 Inhibition and Function of the HDL-Containing Fraction of Plasma in Patients with Stages 3 to 5 CKD.

BACKGROUND AND OBJECTIVES: Systemic inflammation modulates cardiovascular disease risk and functionality of HDL in the setting of CKD. Whether interventions that modify systemic inflammation can improve HDL function in CKD is unknown. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We conducted a post hoc analysis of two randomized, clinical trials, IL-1 trap in participants with GFR 15-59 ml/min per 1.73 m2 (study A) and IL-1 receptor antagonist in participants on maintenance hemodialysis (study B), to evaluate if IL-1 blockade had improved the anti-inflammatory activity (IL-6, TNF-α, and Nod-like receptor protein 3), antioxidant function (superoxide production), and net cholesterol efflux capacity of HDL. HDL function was measured using LPS-stimulated THP-1 macrophages or peritoneal macrophages of apoE-deficient mice exposed to the apoB-depleted, HDL-containing fraction obtained from the plasma of the study participants, collected before and after the interventions to block IL-1 effects. Analysis of covariance was used for between group comparisons. RESULTS: The mean age of the participants was 60±13 years, 72% (n=33) were men, and 39% (n=18) were black. There were 32 CKD (16 IL-1 trap and 16 placebo) and 14 maintenance hemodialysis (7 IL-1 receptor antagonist and 7 placebo) participants. Compared with placebo, IL-1 inhibition, in study A and B reduced cellular expression of TNF-α by 15% (P=0.05) and 64% (P=0.02), IL-6 by 38% (P=0.004) and 56% (P=0.08), and Nod-like receptor protein 3 by 16% (P=0.01) and 25% (P=0.02), respectively. The intervention blunted superoxide production in the treated arm compared with placebo, with the values being higher by 17% in the placebo arm in study A (P<0.001) and 12% in the placebo arm in study B (P=0.004). Net cholesterol efflux capacity was not affected by either intervention. CONCLUSIONS: IL-1 blockade improves the anti-inflammatory and antioxidative properties of the HDL-containing fraction of plasma in patients with stages 3-5 CKD, including those on maintenance hemodialysis.

The nature of death, coping response and intensity of bereavement following death in the critical care environment.

INTRODUCTION: Bereavement, defined as the situation of having recently lost a significant other, is recognised as one of life's greatest stressors and may lead to decrements in health status, psychological morbidity and excess risk of mortality. AIM: The aim of this study was firstly to describe the relationships between the nature of death and bereavement intensity following death in the adult critical care environment and secondly to examine the modifying effects of coping responses on intensity of bereavement reaction. METHOD: Prospective evaluation of the impact of the nature of death and coping responses on bereavement intensity. 78 participants completed a nature of death questionnaire within 2 weeks of bereavement and at 3 and 6 months completed the Core Bereavement Items Questionnaire (CBI-17) and Brief COPE Inventory. RESULTS: At 6 months, univariate variables significantly associated with bereavement intensity were: being unprepared for the death (p<0.001), a drawn out death (p<0.001), a violent death (p=0.007) and if the deceased appeared to suffer more than expected (p=0.03). Multivariate analysis revealed being unprepared for the death appears to account for these relationships. Regarding coping, there were significant increases from 3 to 6 months in both acceptance scales (p=0.01) and planning (p=0.02) on The Brief COPE Inventory. Greater use of emotional support (p=0.02), self-blame (0.003) and denial (p<0.001) were multivariate variables associated with higher bereavement intensity at 6 months. CONCLUSION: The results from this evaluation provide insight into the impact of bereavement after death in the critical care environment and inform potential preventative approaches at the time of death to reduce bereavement intensity.

The complexities of recruiting bereaved family members into a research study in the critical care environment: a discussion paper.

Research on the effects of stressful events on human health and wellbeing has progressed in recent years. One such stress, bereavement, is considered one of life's greatest stresses, requiring significant readjustment. The Cardiovascular Risk in Bereavement study (CARBER) investigated in detail cardiovascular risk factors during the first weeks following the death of a partner or adult child in the critical care environment. The purpose of this paper is to explore the once held perception that the bereaved population should not be involved in research, using an actual illustrative project. The paper specifically focuses on the challenges regarding acceptability and feasibility of recruitment of recently bereaved individuals from the critical care environment. The question of whether bereaved individuals have capacity to consent to involvement in research immediately after loss is considered. The appropriateness of asking newly bereaved individuals to participate in research immediately after the death of their relative is also discussed. The work of the research team demonstrates that early recruitment of bereaved family members into a research project is feasible and acceptable to participants, especially when a multidisciplinary collaborative approach is employed and a personal mode of recruitment used.
