Patient characteristics associated with posttraumatic stress symptoms in intensive care unit survivors during a one-year follow-up: A multicenter study.

BACKGROUND: Intensive care unit (ICU) patients are at risk of suffering from posttraumatic stress symptoms (PTSS) after ICU survival. OBJECTIVES: To describe the prevalence of high levels of PTSS the first year after ICU admission. Further, to identify specific combinations of patient characteristics (latent classes based on pre-ICU data, demographics, and clinical characteristics), and to investigate possible associations among these classes and PTSS at 3, 6, and 12 months after ICU admission. METHODS: Self-reported PTSS were measured with Impact of Event Scale-Revised (IES-R). PTSS and possible predictive factors (pre-ICU data, demographics, and clinical characteristics) were analyzed using descriptive statistics, latent class analysis, and linear mixed model for repeated measures. RESULTS: High PTSS levels (IES-R ≥ 33) were reported by 14.9 % (95 % confidence interval [CI] [10.0; 21.1]), 16.7 % (95 % CI [11.5; 23.1]), and 18.4 % (95 % CI [12.9; 25.0]) of patients (sample 1, n = 174) at 3, 6, and 12 months, respectively. Three latent classes were identified (sample 2, n = 417). PTSS were significantly associated with class 2 (male with longer hospital stay) at 6 months and class 3 (age≥70, lower level of education, higher Simplified Acute Physiology Score, being mechanically ventilated) at all three measurement times. CONCLUSIONS: The prevalence of high levels of PTSS is the greatest 12 months after ICU admission. Health professionals can use this information to be aware of specific groups of ICU patients reporting PTSS during the first year and follow up on these.

Prevalence of and predictive factors associated with high levels of post-traumatic stress symptoms 3 months after intensive care unit admission: A prospective study.

BACKGROUND: Post-traumatic stress symptoms (PTSS) following intensive care unit (ICU) treatment may increase morbidity and mortality. Therefore, it is important to identify patients at risk of suffering from such symptoms. OBJECTIVES: The objective of this study was to describe the prevalence and identify possible predictive factors associated with high levels of PTSS 3 months after ICU admission. METHODS: A multicentre, observational study was carried out in six ICUs in Norway. Patients aged ≥18 years were included. The Impact of Event Scale-Revised measured PTSS 3 months after ICU admission. The impacts of pre-ICU measures; demographic and clinical measures; and daily measures of pain, agitation, and delirium were analysed using univariate and multivariate logistic regression models. RESULTS: In total, of the 273 patients included, the prevalence rate of high levels of PTSS was 19.8% (n = 54) 3 months after ICU admission (95% confidence interval [CI]: [15.2, 25.0]). Female gender, age, pre-ICU unemployment, a minimum of one episode of agitation or delirium, and pre-ICU level of functioning in daily living were all significantly associated with high levels of PTSS in univariate logistic analyses. In the multivariate logistic regression, two models were analysed. In model 1, episodes of agitation during ICU stay (odds ratio [OR] = 4.73; 95% CI: [1.17, 19.0]), pre-ICU unemployment (OR = 3.33; 95% CI: [1.26, 8.81]), and pre-ICU level of functioning in daily living (OR = 0.78; 95% CI: [0.63, 0.96]) (implying lower level) increased the odds of reporting high levels of PTSS. In model 2, pre-ICU unemployment (OR = 2.70; 95% CI: [1.05, 6.93]) and pre-ICU level of functioning in daily living (OR = 0.77; 95% CI: [0.62, 0.95]) (implying lower level) increased the odds of reporting high levels of PTSS. CONCLUSIONS: Healthcare personnel are suggested to be aware of ICU patients' pre-ICU employment status, pre-ICU functioning in daily living, and agitation during ICU stay to identify those at risk of PTSS after discharge.

Interprofessional trust in emergency department - as experienced by nurses in charge and doctors on call.

AIMS AND OBJECTIVES: The aim of this study was to describe that which characterises interprofessional trust in a Norwegian emergency department, as expressed by nurses in charge and doctors on call. BACKGROUND: Interprofessional trust requires knowledge of and skills in interprofessional collaboration. It also requires established trust in fellow collaborators, as well as in the work environment and in the more comprehensive system in which the work is conducted. Nurses in charge and doctors on call who collaborate in the context of an emergency department do so under changing conditions in terms of staff composition and work load. DESIGN: The study was designed in a qualitative, inductive and sequential manner. METHOD: Data were collected from September-November 2013 through four focus group interviews and was analysed by means of qualitative content analysis. RESULTS: The data revealed two themes that were characteristic of interprofessional trust: 'having relational knowledge' and 'being part of a context'. Together, the themes can be understood as equally important to contextual collaboration. A model of interprofessional trust between an individual level and system level was developed from the results. CONCLUSION: The study indicates that interprofessional trust is a changeable phenomenon that has great impact on the possibility for development at an individual level and at a more abstract system level. RELEVANCE TO CLINICAL PRACTICE: Interprofessional trust can be improved by focusing on trust-building activities between staff at the individual level and between staff and organisation at the system level. Supportive activities such as continuous interprofessional education are suggested as valuable to the development and maintenance of trust.
