Validating a pain assessment tool in heterogeneous ICU patients: Is it possible?

Non-communicative adult ICU patients are vulnerable to inadequate pain management with potentially severe consequences. In German-speaking countries, there is limited availability of a validated pain assessment tool for this population. Aim The aim of this observational study was to test the German version of the Critical-Care Pain Observation Tool (CPOT) in a heterogeneous adult ICU population. Methods The CPOT's feasibility for clinical use was evaluated via a questionnaire. For validity and reliability testing, the CPOT was compared with the Behavioural Pain Scale (BPS) and patient's self-report in 60 patients during 480 observations simultaneously performed by two raters. Results The feasibility evaluation demonstrated high satisfaction with clinical usability (85% of responses 4 or 5 on a 5-point Likert scale). The CPOT revealed excellent criterion validity [agreement between CPOT and BPS 94.0%, correlation of CPOT and BPS sum scores r = 0.91 (P < .05), agreement of CPOT with patient self-report 81.4%], good discriminant validity [mean difference of CPOT scores between at rest and non-painful stimulus 0.33 (P < .029), mean difference of CPOT scores between at rest, and painful stimulus 2.19 (P < .001)], for a CPOT cut-off score of >2 a high sensitivity and specificity (93% and 84%), high positive predictive value (85%), and a high negative predictive value (93%). The CPOT showed acceptable internal consistency (Cronbach's alpha 0.79) and high inter-rater reliability [90% agreement, no differences in CPOT sum scores in 64.2% of observations, and correlation for CPOT sum scores r = 0.72 (P < .05)]. Self-report obtained in patients with delirium did not correlate with the CPOT rating in 62% of patients. Conclusion This is the first validation study of the CPOT evaluating all of the described validity dimensions, including feasibility, at once. The results are congruent with previous validations of the CPOT with homogeneous samples and show that it is possible to validate a tool with a heterogeneous sample. Further research should be done to improve pain assessment and treatment in ICU patients with delirium

“Do-not-resuscitate” preferences of the general Swiss population: Results from a national survey

AIMS: To assess the do-not-resuscitate preferences of the general Swiss population and to identify predictors influencing decision-making. Methods: A nationwide web-based survey was conducted in Switzerland on a representative sample of the adult population. The primary endpoint was the preference for a “Do Not Resuscitate” order (DNR Code Status) vs. cardiopulmonary resuscitation (CPR Code Status) in a clinical case vignette of an out-of-hospital cardiac arrest. Secondary endpoint were participants’ own personal preferences for DNR. Results: 1138 subjects participated in the web-based survey, 1044 were included in the final analysis. Preference for DNR code status was found in 40.5% (n = 423) in the case vignette and in 20.3% (n = 209) when making a personal decision for themselves. Independent predictors for DNR Code Status for the case vignette were: Personal preferences for their own DNR Code Status (adjusted OR 2.44, 95%CI 1.67 to 3.55; p < 0.001), intubation following respiratory failure (adjusted OR 1.95, 95%CI 1.20 to 3.18; p = 0.007), time-period after which resuscitation should not be attempted (adjusted OR 0.91, 95%CI 0.89 to 0.93); p < 0.001), and estimated chance of survival in case of a cardiac arrest (adjusted OR per decile 0.91, 95%CI 0.84 to 0.99, p = 0.02; which was overestimated by all participants. Conclusions: Main predictors for a DNR Code Status were personal preferences and the overestimation of good neurological outcome after cardiac arrest. Overestimation of positive outcomes after cardiac arrest seems to influence patient opinion and should thus be addressed during code status discussions

Depression and anxiety in relatives of out-of-hospital cardiac arrest patients: Results of a prospective observational study

Relatives of patients admitted to the intensive care unit (ICU) with out-of-hospital cardiac arrest (OHCA) may suffer from adverse psychological outcomes. We assessed prevalence and risk factors for depression and anxiety in such relatives 90 days after ICU admission.; This study included consecutive relatives of OHCA patients admitted to the ICU of University Hospital in Basel, Switzerland. Relatives were interviewed upon admission regarding psychosocial risk factors and satisfaction with communication. Symptoms of depression and anxiety were assessed by Hospital Anxiety and Depression Scale (HADS) 90 days after inclusion.; Of 101 included relatives, 17% and 13% of relatives reported symptoms of depression and anxiety, respectively. Witnessing cardiopulmonary resuscitation was associated with depression (gender- and age-adjusted odds ratio [OR] 6.71; 95%CI 1.27 to 35.34; p = .025). Satisfaction with information and decision-making was associated with lower risk of depression (adjusted OR 0.95; 95%CI 0.91 to 0.99; p = .013). Unemployment (adjusted OR 10.42; 95%CI 1.18 to 92.35; p = .035) and lower perceived health status were associated with anxiety (adjusted OR 0.93; 95%CI 0.87 to 0.99; p = .025).; Many relatives of OHCA patients report symptoms of depression and anxiety after 90 days. Improving initial care and communication may help to reduce these risks
