Symptoms of Anxiety, Depression, and Stress among Families of Critically Ill Patients with COVID-19: A Longitudinal Clinical Trial.

Rationale: Families of critically ill patients with coronavirus disease (COVID-19) may be at particularly high risk for anxiety, depression, and post-traumatic stress disorder after hospital discharge. Objectives: To assess symptoms of anxiety, depression, and stress among families of patients with COVID-19 during and after intensive care unit (ICU) admissions and to use qualitative methods to determine the sources of emotional distress. Methods: Families of patients with COVID-19 who participated in an ICU study were approached for participation in this post-hospital discharge study. Participants completed the Hospital Anxiety and Depression Scale (HADS) and the Impact of Events Scale-Revised (IES-R) at up to three points during the ICU stay and once after the ICU stay. Mixed-effects models were used to compare trajectories of HADS and IES-R scores over the ICU and post-ICU periods. Telephone interviews with participants were evaluated using thematic content analysis. Results: Among the 90 families that participated from September 2020 to April 2021, 47 respective patients were alive and 43 were deceased. Average HADS anxiety, HADS depression, and IES-R scores after hospital discharge were significantly higher (greater symptom burden) among families of deceased versus surviving patients: 9.2 (95% confidence interval [CI], 7.8-10.6) versus 6.3 (95% CI, 4.9-7.6) (P < 0.01), 7.1 (95% CI, 5.7-8.6) versus 3.2 (95% CI, 2.3-4.1) (P < 0.001), and 36.1 (95% CI, 31.0-41.2) versus 20.4 (95% CI, 16.1-24.8) (P < 0.001), respectively. HADS anxiety and HADS depression scores began to diverge during the ICU stay, whereas IES-R scores diverged after the stay for families of surviving versus deceased patients. Qualitative analysis confirmed a higher burden of psychological symptoms among families of deceased patients. Memories from the ICU stay became a focal point for participants who lost their loved ones, whereas families of surviving patients were able to look positively toward the future. In addition, families of deceased patients often viewed friends and family as sources of stress, whereas families of surviving patients typically viewed their community as a source of support. Conclusions: Patient death was associated with symptoms of anxiety, depression, and post-traumatic stress disorder among families of ICU patients with COVID-19. Psychological support interventions may be most beneficial for families of patients who died of COVID-19. Clinical trial registered with www.clinicaltrials.gov (NCT04501445).

Piloting Group-Based Behavioral Activation Therapy for Families of Deceased COVID-19 Patients.

Surrogate decision-making is a stressful process for many family members of critically ill patients. The COVID-19 pandemic may have amplified the risk for anxiety, depression, and posttraumatic stress disorder (PTSD) symptoms in ICU surrogates. OBJECTIVES: This study piloted an online group-based behavioral intervention with family members of deceased COVID-19 patients. Participant engagement, perceptions, and responses related to the intervention were assessed. DESIGN: A single-arm pilot study was conducted with bereaved families. Quantitative analysis of measures of anxiety, depression, and PTSD symptoms was conducted with mixed models. Qualitative data were analyzed to identify themes in surrogates' experiences with the intervention. SETTING: Participants were recruited from ICUs at a tertiary academic medical center. Participants completed the intervention, measures, and interviews online. SUBJECTS: Participants were family members of patients who died from COVID-19. INTERVENTIONS: The intervention involved six online group-based behavioral activation sessions. Sessions covered topics pertinent to grieving and engagement in personally meaningful activities. MEASUREMENTS AND MAIN RESULTS: Semi-structured interviews explored participants' experiences with the intervention. Surrogates also completed measures of anxiety, depression, and PTSD symptoms before and after the intervention. Nineteen of 26 participants (73.1%) completed the study. Thematic analysis suggested that surrogates found the group helpful for overcoming perceived isolation, receiving validation, and developing coping skills. Significant pre-to-post reductions were observed in symptoms of Hospital and Anxiety Disorder Scale (HADS) anxiety (pre-mean = 9.27, sd = 5.30 vs post-mean = 6.80, sd = 4.16; p = 0.0271), HADS depression (pre-mean =6 .65, sd = 4.58 vs post- mean = 4.89, sd = 3.40; p = 0.0436), and Impact of Events Scale-Revised PTSD (pre-mean = 36.86, sd = 16.97 vs post-mean = 24.14, sd = 13.49; p = 0.0008). LIMITATIONS: This was a preliminary study based on qualitative and self-report measures. Future studies should include a control group. CONCLUSIONS: Online group-based behavioral activation therapy appears to be a potentially useful intervention for family members of ICU patients who died from COVID-19.

Ethical challenges in developing drugs for psychiatric disorders.

As the classification of mental disorders advances towards a disease model as promoted by the National Institute of Mental Health (NIMH) Research Domain Criteria (RDoC), there is hope that a more thorough neurobiological understanding of mental illness may allow clinicians and researchers to determine treatment efficacy with less diagnostic variability. This paradigm shift has presented a variety of ethical issues to be considered in the development of psychiatric drugs. These challenges are not limited to informed consent practices, industry funding, and placebo use. The consideration for alternative research models and quality of research design also present ethical challenges in the development of psychiatric drugs. The imperatives to create valid and sound research that justify the human time, cost, risk and use of limited resources must also be considered. Clinical innovation, and consideration for special populations are also important aspects to take into account. Based on the breadth of these ethical concerns, it is particularly important that scientific questions regarding the development of psychiatric drugs be answered collaboratively by a variety of stakeholders. As the field expands, new ethical considerations will be raised with increased focus on genetic markers, personalized medicine, patient-centered outcomes research, and tension over funding. We suggest that innovation in trial design is necessary to better reflect practices in clinical settings and that there must be an emphasized focus on expanding the transparency of consent processes, regard for suicidality, and care in working with special populations to support the goal of developing sound psychiatric drug therapies.

Client and key worker ratings of need in first-episode psychosis early intervention programmes.

AIM: The aim of this study was to fill a gap in the literature by examining agreement on need as rated by clients and their key workers from first-episode psychosis early intervention programmes. Compared with adult populations and more chronic courses of illness, these clients may have unique needs given the onset of their illness in adolescence or early adulthood. METHODS: Needs agreement between clients and key workers was assessed using the Camberwell Assessment of Need in a sample of 188 client-key worker pairs recruited from six early intervention programmes in Ontario, Canada. Ratings were assessed with percentage agreement and prevalence-adjusted Cohen's kappa. RESULTS: At the aggregate level, both clients and key workers rated a mean of 2.6 unmet needs. Compared with other diagnoses, key workers rated significantly more unmet need in clients with primary psychotic disorders. Agreement between individual client and key worker ratings was highest (adjusted κ > 0.85) in the domains of telephone, risk to others, child care and accommodation. Lowest agreement (adjusted κ < 0.4) was found in the domains of psychological distress, sexual expression, company, daytime activities and intimate relationships. CONCLUSIONS: While congruence is present in concrete domains, there is substantial variability in how clients and their key workers perceive need in more personal areas. The initial focus of care may necessarily be on needs such as shelter, food and treatment; however, subsequent care should incorporate a shared assessment of need to support strong relationships with providers and ongoing engagement in treatment.

The effects of gender on adolescent suicide in ontario, Canada.

OBJECTIVE: Identify patterns of suicide amongst male and female adolescents aged 11-18 years in Ontario. METHOD: All 370 adolescent suicides in Ontario between January 2000 and November 2006 were analyzed. Previous attempts, history of psychiatric treatment, location committed and method of suicide were assessed. Data was analyzed using 2-tailed t-tests and chi-square without Yates' correction. RESULTS: Male adolescent suicide was twice as common as female suicide. Males were more likely to use violent methods (p=0.0352) and females were more likely to have a history of a previous suicide attempt (p=0.0001). CONCLUSIONS: While most of the data agree with previous studies in adult populations, the ratio of male to female suicides was much lower in our adolescent population.

Temporal change, reproducibility, and interobserver variability in pressure-volume curves in adults with acute lung injury and acute respiratory distress syndrome.

OBJECTIVES: To assess the reproducibility of the static pressure-volume curve of the respiratory system by using a "mini-syringe" technique; to assess the temporal change in upper (UIP) and lower inflection points (LIP) measured from pressure-volume curves of the respiratory system; to assess the inter- and intraobserver variability in detection of the UIP and LIP in patients with acute lung injury (ALI)/acute respiratory distress syndrome (ARDS); and to compare the syringe and multiple occlusion techniques for determining LIP and UIP. DESIGN: Prospective observational study. SETTING: Academic medical-surgical critical care unit. PATIENTS: Consecutive patients with ALI or ARDS. INTERVENTIONS: Static inspiratory pressure-volume curves of the respiratory system were determined twice on day 1 of diagnosis of ALI/ARDS and then once daily for up to 6 days by using the syringe technique. Pressure-volume curves were determined from zero positive end-expiratory pressure. At each time point, three separate measurements of the pressure-volume curve were made to determine reproducibility. A 100-mL graduated syringe was used to inflate patients' lungs with 50- to 100-mL increments up to an airway pressure of 45 cm H2O or a total volume of 2 L; each volume step was maintained for 2-3 secs until a plateau airway pressure was recorded. On day 1, the static pressure-volume curve also was determined by using the multiple occlusion technique. In a random and blinded sequence, the pressure-volume curves were examined visually by three critical care physicians on three different occasions, to determine the intra- and interobserver variability in visual detection of the LIP and UIP. Observers were given objective instructions to visually identify LIP and UIP. MEASUREMENTS AND MAIN RESULTS: Eleven patients were enrolled, with a total of 134 pressure-volume curves generated. LIP and UIP could be detected in 90-94% and 61-68% of curves, respectively. When the three successive pressure-volume curves were compared, both the LIP and UIP were within 3 cm H2O in >65% of curves. The index of reliability (intraclass correlation coefficient) in LIP and UIP was 0.92 and 0.89 for interobserver variability and 0.90 and 0.88 for intraobserver variability. Daily variability was as high as 7 cm H2O for LIP and 5 cm H2O for UIP. When pressure-volume curves obtained by using the multiple occlusion and syringe techniques were compared, LIP was within 2 cm H2O, and UIP was within 4 cm H2O with the two techniques. CONCLUSIONS: The static pressure-volume curve of the respiratory system is reasonably reproducible, thus avoiding the need for multiple measurements at a single time. We found excellent interobserver and intraobserver correlation in manual identification of the LIP and UIP. Both LIP and UIP show appreciable daily variability in patients with ALI/ARDS. The multiple occlusion and syringe techniques generate similar values for LIP and UIP.

Safety of pressure-volume curve measurement in acute lung injury and ARDS using a syringe technique.

STUDY OBJECTIVES: To assess the safety of frequent pressure-volume (PV) curve measurement in patients with acute lung injury (ALI)/ARDS. DESIGN: Prospective observational study. SETTING: Academic medical-surgical critical care unit. PATIENTS: Consecutive patients with ALI or ARDS. INTERVENTIONS: Static inspiratory PV curves of the respiratory system were determined twice on day 1, then once daily for up to 6 days using a syringe. At each time point, three separate measurements of the PV curve were made. A 100-mL graduated syringe was used to inflate patients' lungs with 50- to 100-mL increments up to an airway pressure of 45 cm H(2)O or a total volume of 2 L; each volume step was maintained for 2 to 3 s until a plateau airway pressure was recorded. Outcome measures were mean arterial BP, heart rate (HR), and oxyhemoglobin saturation (SpO(2)) prior to and immediately after PV curve measurement. There were a priori criteria for procedure discontinuation if poorly tolerated. MEASUREMENTS AND RESULTS: Eleven patients were enrolled with a total of 134 PV curves generated. SpO(2) was 93 +/- 4% (mean +/- SD) before and fell to a nadir of 89 +/- 5% during PV curve measurement (p < 0.001), but increased to 97 +/- 4% immediately afterwards (p < 0.001, before vs after). HR rose from 106 +/- 22 to 108 +/- 22 beats/min immediately after the maneuver (p < 0.001). Mean arterial BP was 93 +/- 15 mm Hg before and 100 +/- 17 mm Hg immediately afterwards (p < 0.001). During PV curve measurement, systolic BP in one patient fell to 64 mm Hg from 113 mm Hg; in another patient, SpO(2) dropped to 79% from 89%. Both changes were transient. The study was discontinued in one patient because of inability to tolerate zero positive end-expiratory pressure; in another patient, the study was discontinued because of the development of subcutaneous emphysema. CONCLUSIONS: PV curve measurement by syringe technique is well tolerated in most patients. Nonetheless, the maneuver may cause significant changes in oxygenation and/or hemodynamics, necessitating close monitoring.
