AIMS AND OBJECTIVES To describe the recovery of trauma intensive care patients up to six months posthospital discharge. BACKGROUND Injury is a leading cause of preventable mortality and morbidity worldwide, with approximately 10% of hospitalised trauma patients being admitted to intensive care. Intensive care patients experience significant ongoing physical and psychological burden after discharge; however, the patterns of recovery and the subgroups of intensive care patients who experience the greatest burden are not described. DESIGN This prospective cohort study was conducted in one tertiary referral hospital in south-east Queensland, Australia. METHODS Following ethics approval, injured patients who required admission to intensive care provided consent. Participants completed questionnaires prior to hospital discharge (n = 123) and one (n = 93) and six months (n = 88) later. Data included demographic and socioeconomic details, pre-injury health, injury characteristics, acute care factors, postacute factors [self-efficacy, illness perception, perceived social support and psychological status as measured by the Kessler Psychological Distress Scale (K10) and the PTSD Civilian Checklist] and health status (SF-36). RESULTS All participants required ongoing support from healthcare providers in the six months after discharge from hospital, and approximately half required support services such as accommodation and home modifications. Approximately 20% of participants reported post-traumatic stress symptoms, while approximately half the participants reported psychological distress. Average quality of life scores were significantly below the Australian norms both one and six months postdischarge. CONCLUSIONS Trauma intensive care patients rely on ongoing healthcare professional and social support services. Compromised health-related quality of life and psychological health persists at six months. RELEVANCE TO CLINICAL PRACTICE Effective discharge planning and communication across the care continuum is essential to facilitate access to healthcare providers and other support services in the community setting.

Objective:To determine the association between anxiety during critical illness and symptoms of anxiety and depression over 6 months after ICU discharge in survivors of intensive care treatment. Design:Longitudinal study. Setting:One closed mixed ICU in an adult tertiary hospital in Brisbane, Australia. Patients:Participants (n = 141) were adults (≥ 8 yr), admitted to ICU for at least 24 hours, able to communicate either verbally or nonverbally, understand English, and open their eyes spontaneously or in response to voice. Interventions:None. Measurements and Main Results:The outcomes of symptoms of anxiety and depression over 6 months after ICU discharge were assessed using the Hospital Anxiety Depression Scale. The primary variable of interest was anxiety during critical illness. Two components of anxiety (state and trait) were assessed during critical illness using the Faces Anxiety Scale and the trait component of the State-Trait Anxiety Inventory. Perceived social support, cognitive functioning, and posttraumatic stress symptoms were also assessed using standardized instruments. Clinical and demographic data were obtained from patients and medical records. Participants were followed up in hospital wards and at 3 and 6 months after ICU discharge. During ICU treatment, 81 of the 141 participants (57%) reported moderate to severe levels of state anxiety. Of the 92 participants who completed the surveys at the 6-month follow-up, 26 participants (28%) reported symptoms of anxiety and 21 (23%) symptoms of depression. Symptoms of anxiety and depression were strongly correlated in this cohort of survivors. Trait anxiety was significantly associated with both anxiety and depression symptoms over time; however, state anxiety was not associated with either outcome. Participants who reported post-ICU memories of intra-ICU anxiety were significantly more anxious during recovery over 6 months. Cognitive functioning and posttraumatic stress symptoms were both significantly associated with anxiety and depression symptoms over time. Conclusion:Symptoms of anxiety and depression are a significant issue for general ICU survivors. Trait anxiety was significantly associated with adverse emotional outcomes over 6 months after ICU discharge. There was also a significant relationship between post-ICU memories of intra-ICU anxiety and anxiety during recovery. Interventions to reduce anxiety during critical illness need to be considered and evaluated for their longer term benefits for survivors of critical illness.

Objectives:This study was designed to examine changes in function over time after injury and to identify factors associated with long-term recovery that may be amenable to change through intervention. Design:Prospective cohort study. Setting:Intensive care in a tertiary hospital in Queensland, Australia. Patients:Adult (n = 123) admitted to intensive care for treatment of injury. Interventions:Data were collected prior to hospital discharge and 1, 6, 12, and 24 months post injury. Data included demographics, preinjury health, injury characteristics, acute care factors, psychosocial measures, and health status. Linear mixed-effects models were used to identify factors associated with physical function and mental health over time. Measurements and Main Results:Physical function and mental health improved over time; however, the averages remained below Australian norms at 24 months. Optimistic perception of illness and greater self-efficacy were potentially modifiable factors associated with improved mental health and physical function over time. Greater perceived social support, also potentially modifiable, was associated with improved mental health. Injury insurance and income were significant nonmodifiable factors for mental health, with mental health gains associated with higher income. Hospital length of stay and injury insurance were nonmodifiable factors linked with physical function. Conclusions:Improvements in physical function and mental health are evident in the 24 months following injury, but most patients remain below Australian population norms. Factors that were associated with physical function and mental health outcomes over time that are potentially amenable to change include illness perception, self-efficacy, and perceived social support.

OBJECTIVE The aim of this paper was to identify factors associated with self-efficacy for managing recovery in the trauma intensive care population. INTRODUCTION Injury accounts for 6.5% of disease burden in Australia, with similar levels being reported in other developed countries. While some studies regarding self-efficacy have identified a relationship to patient recovery post acute injury, others have been inconclusive. This study will identify factors associated with self-efficacy for managing recovery in the trauma intensive care population. METHODS A prospective cohort study of patients aged ≥ 18 years, admitted to a metropolitan tertiary hospital in South East Queensland between June 2008 and August 2010 for the acute treatment of injury. Demographic, injury, acute care and psychosocial factors were considered. The primary outcome was self-efficacy measured by the 6-item self-efficacy scale (SES) 1 and 6 months post hospital discharge. All factors significant (p<0.10) on univariate analysis were included in multivariable modelling where p<0.05 was considered significant. RESULTS A total of 88 patients were included. The mean self-efficacy score at 1 and 6 months was similar (6.8 vs 6.9 respectively). Self-efficacy at 1 month, psychological distress (K-10) Score and illness perception (K10) Score accounted for 68.4% (adjusted R(2)) of the variance in 6 month self-efficacy (F3,75)=57.17, p<0.001. Illness perception was the strongest contributor to 6 month self-efficacy (beta=-0.516), followed by psychological distress (beta=-0.243) and self-efficacy at 1 month (beta=0.205). CONCLUSION Significant factors associated with self-efficacy for managing recovery at 6 months included 1 month self-efficacy, illness perception and psychological distress. To promote patient recovery, screening patients at 1 month in order to commence relevant interventions could be beneficial.

BACKGROUND Posttraumatic stress symptoms are common after intensive care treatment. The influence of anxiety during critical illness on the development of posttraumatic stress symptoms needs to be investigated. OBJECTIVE To determine the association between anxiety during critical illness (state and trait components) and posttraumatic stress symptoms over six months after ICU discharge. METHODS Prospective study including 141 patients admitted ≥24h to a closed mixed adult ICU in a tertiary hospital. State anxiety was assessed with the Faces Anxiety Scale during ICU stay. Trait anxiety was measured with the State-Trait Anxiety Inventory Form Y-2. Posttraumatic stress symptoms were measured at three and six months after ICU discharge using the Post-Traumatic Stress Symptoms 10-Question Inventory. Clinical and demographical data were also collected. Mixed effect regression models were used to determine if state and trait anxiety were factors significantly associated with posttraumatic stress symptoms over time. RESULTS Moderate to severe levels of state anxiety in ICU were reported by 81 (57%) participants. Levels of trait anxiety (median 36 IQR: 29-47) were similar to the Australian population. High levels of posttraumatic stress symptoms occurred at three (n=19, 19%) and six months (n=15, 17%). Factors independently associated with posttraumatic stress symptoms were trait anxiety (2.2; 95% CI, 0.3-4.1; p=0.02), symptoms of anxiety after ICU discharge (0.6; 95% CI, 0.2-1.1; p=0.005), younger age (-1.4; 95% CI, -2.6 to -0.2; p=0.02) and evidence of mental health treatment prior to the ICU admission (5.2; 95% CI, 1.5-8.9; p=0.006). CONCLUSIONS Posttraumatic stress symptoms occurred in a significant proportion of ICU survivors and were significantly associated with higher levels of trait anxiety, younger age, mental health treatment prior to the ICU admission and more symptoms of anxiety after ICU discharge. Early assessment and interventions directed to reduce state and trait anxiety in ICU survivors may be of benefit.

BACKGROUND Anxiety is an unpleasant emotion that most intensive care patients experience. This emotion is an important issue in intensive care settings because of its prevalence, adverse effects and severity. Little is known about the factors associated with state and trait anxiety during critical illness. OBJECTIVES To describe the patterns of state anxiety reported by intensive care patients, and identify factors associated with state and trait anxiety. DESIGN Prospective observational cohort study. SETTINGS One mixed intensive care unit in Brisbane, Australia. PARTICIPANTS Adults (n=141, ≥18 years) admitted to the intensive care unit for ≥24h; able to communicate verbally or non-verbally; understand English; and, open their eyes spontaneously or in response to voice. METHODS Outcomes were state anxiety as measured by the Faces Anxiety Scale and trait anxiety as measured by the State-Trait Anxiety Inventory. Pre-intensive care factors tested for possible associations with both state and trait anxiety were: age, gender, marital status, employment status, level of education, smoking status, personality trait of optimism and evidence of mental health care/treatment. Intra-intensive care factors tested were: reason for admission to the intensive care unit, delirium, pain, airway status, hours of mechanical ventilation, severity of illness, days of stay in intensive care, exposure to corticosteroids, opioids, benzodiazepines, anxiolytics, antidepressants, beta-blockers, anaesthetic agents and analgesics; length of sedation and analgesia and total doses of sedatives and analgesics. RESULTS Of 141 participants, 98 (70%) were male with an average age of 54 (standard deviation: ±15) years and stayed in intensive care for about 4 (Interquartile Range: 3-7) days. The majority (n=115; 82%) of participants experienced state anxiety at least once during their stay in intensive care, with 57% reporting moderate to severe levels. Factors related to state anxiety in intensive care were pain and trait anxiety. Factors associated with trait anxiety were trait optimism, state anxiety, evidence of mental health care/treatment and age. CONCLUSIONS This study provides a better understanding of contributing factors for anxiety in the critically ill. Trait anxiety and state anxiety were significantly associated with each other, namely, patients who were anxious by nature experienced higher levels of state anxiety, which persisted throughout their stay in the intensive care unit. Recognising the importance of state and trait anxiety assessments using validated tools and determining ways to manage anxiety in the critically ill are critical aspects of the intensive care nurses role.
