“…We were not able to tell whether they had suffered from ASD in this study. ASD is a risk factor for the development of PTSD [33]. More attention and screening of these patients for ASD symptoms, followed by proper support and treatment, is needed, given the correlation between the two disorders.…”

Background: Although studies on the effectiveness of the use of ICU diaries on psychiatric disorders and quality of life have been published, the results still seem to be controversial. The study aimed to determine the effects of using an ICU diary on psychiatric disorders, sleep quality, and quality of life (QoL) in adult ICU survivors in China. Methods: One hundred and twenty-six patients who underwent a scheduled cardiac surgery and were expected to stay ≥ 24 h in ICU were randomized to two groups (63 in each group). The patients in the intervention group received the use of ICU diaries during the period of post-ICU follow-up, while the patients in the control group received usual care without ICU diaries. The primary outcome was significant PTSD symptoms (Chinese version of Impact of Event Scale-Revised, IES-R; total score ≥ 35 was defined as significant PTSD symptoms) and its severity in patients 3 months post-ICU. The secondary outcomes included memories of the ICU at 1 month, QoL (Medical Outcomes Study 36-item Short-Form, SF-36), sleep quality (Pittsburgh Sleep Quality Index Questionnaire, PSQI), anxiety, and depression symptoms (Hospital Anxiety and Depression Scale, HADS) at 3 months. Results: Eighty-five and 83 patients completed the follow-up interviews at 1 month and 3 months post-ICU, respectively. Significant PTSD symptoms were reported by 6 of 41 (14.63%) in the intervention group vs 9 of 42 (21.43%) in the control group (risk difference, − 9% [95% CI, − 2% to 21%], P = 0.10). There was no significant differences between groups in IES-R score, symptoms of intrusion, symptoms of avoidance, numbers of memories of feeling and delusional memories, SF-36 score and anxiety score (P > 0.05), while significant differences were found in symptom of hyperarousal score, numbers of factual memories and PSQI score (P < 0.05). No adverse effect was reported. Conclusions: Using an ICU diary is not useful for preventing PTSD symptoms and anxiety symptoms and preserving the quality of life of the patients at 3 months post-ICU, while it significantly improves the survivor's factual memory of ICU and sleep quality, and prevents the hyperarousal symptom.

“…l Contrary to evidence suggesting that focusing on acute stress and its causes early in the ICU may help, 113 patients may have still been too ill to absorb and put into practice the therapeutic messages taught in the stress support sessions. This is shown by the high numbers of patients being discharged from critical care prior to regaining the necessary cognitive capacity to consent.…”

Background High numbers of patients experience severe acute stress in critical care units. Acute stress has been linked to post-critical care psychological morbidity, including post-traumatic stress disorder (PTSD). Previously, a preventive, complex psychological intervention [Psychological Outcomes following a nurse-led Preventative Psychological Intervention for critically ill patients (POPPI)] was developed by this research team, to be led by nurses, to reduce the development of PTSD symptom severity at 6 months. Objectives The objectives were to (1) standardise and refine the POPPI intervention, and, if feasible, (2) evaluate it in a cluster randomised clinical trial (RCT). Design Two designs were used – (1) two feasibility studies to test the delivery and acceptability (to patients and staff) of the intervention, education package and support tools, and to test the trial procedures (i.e. recruitment and retention), and (2) a multicentre, parallel-group, cluster RCT with a baseline period and staggered roll-out of the intervention. Setting This study was set in NHS adult, general critical care units. Participants The participants were adult patients who were > 48 hours in a critical care unit, receiving level 3 care and able to consent. Interventions The intervention comprised three elements – (1) creating a therapeutic environment in critical care, (2) three stress support sessions for patients identified as acutely stressed and (3) a relaxation and recovery programme for patients identified as acutely stressed. Main outcome measures Primary outcome – patient-reported symptom severity using the PTSD Symptom Scale – Self Report (PSS-SR) questionnaire (to measure clinical effectiveness) and incremental costs, quality-adjusted life-years (QALYs) and net monetary benefit at 6 months (to measure cost-effectiveness). Secondary outcomes – days alive and free from sedation to day 30; duration of critical care unit stay; PSS-SR score of > 18 points; depression, anxiety and health-related quality of life at 6 months; and lifetime cost-effectiveness. Results (1) A total of 127 participants were recruited to the intervention feasibility study from two sites and 86 were recruited to the RCT procedures feasibility study from another two sites. The education package, support tools and intervention were refined. (2) A total of 24 sites were randomised to the intervention or control arms. A total of 1458 participants were recruited. Twelve sites delivered the intervention during the intervention period: > 80% of patients received two or more stress support sessions and all 12 sites achieved the target of > 80% of clinical staff completing the POPPI online training. There was, however, variation in delivery across sites. There was little difference between baseline and intervention periods in the development of PTSD symptom severity (measured by mean PSS-SR score) at 6 months for surviving patients in either the intervention or the control group: treatment effect estimate −0.03, 95% confidence interval (CI) −2.58 to 2.52; p = 0.98. On average, the intervention decreased costs and slightly improved QALYs, leading to a positive incremental net benefit at 6 months (£835, 95% CI −£4322 to £5992), but with considerable statistical uncertainty surrounding these results. There were no significant differences between the groups in any of the secondary outcomes or in the prespecified subgroup analyses. Limitations There was a risk of bias because different consent processes were used and as a result of the lack of blinding, which was mitigated as far as possible within the study design. The intervention started later than anticipated. Patients were not routinely monitored for delirium. Conclusions Among level 3 patients who stayed > 48 hours in critical care, the delivery of a preventive, complex psychological intervention, led by nurses, did not reduce the development of PTSD symptom severity at 6 months, when compared with usual care. Future work Prior to development and evaluation of subsequent psychological interventions, there is much to learn from post hoc analyses of the cluster RCT rich quantitative and qualitative data. Trial registration This trial is registered as ISRCTN61088114 and ISRCTN53448131.

“…However, it is the perception of life threat that likely leads to patient‐perceived threat rather than actual life threat. Fourth, although the PCL‐5 is a well‐validated measurement tool that is frequently used in research to assess PTSD symptoms, it is a screening tool and not a diagnostic test for PTSD.…”

Background Our objectives were to test whether during a potentially life‐threatening medical emergency, perceived threat (a patient’s sense of life endangerment) in the emergency department (ED) is common and associated with the subsequent development of posttraumatic stress disorder (PTSD) symptoms. Methods This study was an ED‐based prospective cohort study in an academic hospital. We included adult patients requiring acute intervention in the ED for resuscitation of a potentially life‐threatening medical emergency, defined as respiratory or cardiovascular instability. We measured patient‐perceived threat in the ED using a validated patient self‐assessment measure (score range = 0 to 21, with higher scores indicating greater perceived threat). We performed blinded assessment of PTSD symptoms 30 days after discharge using the PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders‐Fifth Edition (PCL‐5). Results Ninety‐nine of 113 (88%) patients completed follow‐up, with 98% reporting some degree of perceived threat, median (interquartile range [IQR]) perceived threat score 12 (6 to 17), and 72% reported PTSD symptoms in relation to their ED visit (median [IQR] PCL‐5 score = 7 [0 to 30]). Patients with respiratory instability had higher median (IQR) perceived threat scores (16 [9 to 18] vs. 9 [6 to 14)] and PCL‐5 scores (10 [2 to 40] vs. 3 [0 to 17]) compared to patients without respiratory instability. In a multivariable linear regression model adjusting for potential confounders, greater perceived threat in the ED was independently associated with higher PCL‐5 scores (β = 0.79, 95% confidence interval [CI] = 0.15 to 1.42). Among the individual perceived threat items, the feeling of helplessness during resuscitation had the strongest association with PCL‐5 score (β = 5.24, 95% CI = 2.29 to 8.18). Conclusions Perceived threat during potentially life‐threatening emergencies is common and independently associated with development of PTSD symptoms. Additional research to test whether reduction of perceived threat in the ED attenuates the development of PTSD symptoms following potentially life‐threatening emergencies is warranted.

Early Interventions for the Prevention of Posttraumatic Stress Symptoms in Survivors of Critical Illness: A Qualitative Systematic Review

Abstract: Despite a paucity of high-quality clinical investigations, the preponderance of evidence to date suggests that 1) posttraumatic stress disorder among survivors of critical illness may be preventable and 2) early interventions may be the most effective.
