The association between intensive care unit admission and subsequent depression in patients with diabetes

Psychiatric Symptoms in Acute Respiratory Distress Syndrome Survivors: A 1-Year National Multicenter Study

OBJECTIVE

To evaluate prevalence, severity, and co-occurrence of and risk factors for depression, anxiety, and posttraumatic stress disorder symptoms over the first year after acute respiratory distress syndrome.

DESIGN

Prospective longitudinal cohort study.

SETTINGS

Forty-one Acute Respiratory Distress Syndrome Network hospitals across the United States.

PATIENTS

Six hundred ninety-eight acute respiratory distress syndrome survivors.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Psychiatric symptoms were evaluated by using the Hospital Anxiety and Depression Scale and Impact of Event Scale-Revised at 6 and 12 months. Adjusted prevalence ratios for substantial symptoms (binary outcome) and severity scores were calculated by using Poisson and linear regression, respectively. During 12 months, a total of 416 of 629 patients (66%) with at least one psychiatric outcome measure had substantial symptoms in at least one domain. There was a high and almost identical prevalence of substantial symptoms (36%, 42%, and 24% for depression, anxiety, and posttraumatic stress disorder) at 6 and 12 months. The most common pattern of co-occurrence was having symptoms of all three psychiatric domains simultaneously. Younger age, female sex, unemployment, alcohol misuse, and greater opioid use in the ICU were significantly associated with psychiatric symptoms, whereas greater severity of illness and ICU length of stay were not associated.

CONCLUSIONS

Psychiatric symptoms occurred in two thirds of acute respiratory distress syndrome survivors with frequent co-occurrence. Sociodemographic characteristics and in-ICU opioid administration, rather than traditional measures of critical illness severity, should be considered in identifying the patients at highest risk for psychiatric symptoms during recovery. Given high co-occurrence, acute respiratory distress syndrome survivors should be simultaneously evaluated for a full spectrum of psychiatric sequelae to maximize recovery.

One-year outcomes of rosuvastatin versus placebo in sepsis-associated acute respiratory distress syndrome: prospective follow-up of SAILS randomised trial

BACKGROUND

Prior randomised trials have evaluated statins in patients with sepsis and acute respiratory distress syndrome (ARDS), but there has been no comprehensive evaluation of long-term effects, despite potential neuromuscular and mental health adverse effects of these drugs.

AIM

To evaluate the effect of rosuvastatin versus placebo on survival, physical function and performance, and mental health outcomes in patients with sepsis-associated ARDS.

METHODS

Prospective follow-up evaluation of the ARDS Clinical Trials Network Statins for Acutely Injured Lungs from Sepsis trial of rosuvastatin versus placebo in 568 mechanically ventilated patients with sepsis-associated ARDS, with blinded 6-month outcome assessment performed in the 272 eligible survivors for age-adjusted and sex-adjusted 36-Item Short Form Health Survey (SF-36) physical function and mental health domains, and in 84 eligible survivors for the 6 min walk test, along with secondary outcomes evaluations of survival, and additional patient-reported and performance-based measures at 6-month and 12-month follow-up.

RESULTS

Over 1-year follow-up, there was no significant difference in cumulative survival in the rosuvastatin versus placebo groups (58% vs 61%; p=0.377), with survivors demonstrating substantial impairments in physical function and mental health. Rosuvastatin versus placebo had no effect (mean treatment effect (95% CI)) on SF-36 physical function (0 (-7 to 8), p=0.939) or mental health (-6 (-12 to 1) p=0.085) domains, 6 min walk distance (per cent predicted: 2 (-9 to 14), p=0.679) or the vast majority of secondary outcomes.

CONCLUSIONS

Over 1-year follow-up, patients with sepsis-associated ARDS had high cumulative mortality, with survivors commonly experiencing impairments in physical functioning and performance, and mental health. Randomisation to rosuvastatin had no effect on these outcomes.

Hospital-level factors associated with report of physical activity in patients on mechanical ventilation across Washington State

RATIONALE

Use of physical and/or occupational therapy in the intensive care unit (ICU) is safe, feasible, and demonstrates improvements in functional status with early administration. Access to physical and/or occupational therapy in the ICU is variable, with little known regarding its use in community ICUs.

OBJECTIVES

Determine what proportion of hospitals across Washington State report use of physical activity in mechanically ventilated patients and investigate process of care factors associated with reported activity delivery.

METHODS

Cross-sectional telephone interview survey study of nurse managers in hospitals caring for patients on mechanical ventilation across Washington State in 2013. Survey responses were linked with hospital-level data available in the Washington State Department of Health Comprehensive Hospital Abstract Reporting System database. Chi-square testing was used to explore unadjusted associations between potential process of care factors and report on activity delivery. Two multivariable logistic regression models were developed to explore the association between presence of a mobility protocol and report on delivery of activity.

MEASUREMENTS AND MAIN RESULTS

We identified 54 hospitals caring for patients on mechanical ventilation; 47 participated in the survey (response rate, 85.5%). Nurse managers from 36 (76.6%) hospitals reported use of physical activity in patients on mechanical ventilation, with 22 (46.8%) reporting use of high-level physical activity (transferring to chair, standing or ambulating) and 24 (51.1%) reporting use in high-severity patients (patients requiring mechanical ventilation and/or vasopressors). Presence of a written ICU activity protocol (odds ratio [OR], 5.54; 95% confidence interval [CI], 1.60-19.18; P = 0.006), hospital volume (OR, 5.33; 95% CI, 1.54-18.48; P = 0.008), and academic affiliation (OR, 4.40; 95% CI, 1.23-15.63; P = 0.02) were associated with report of higher level activity. Presence of a written ICU activity protocol (OR, 6.00; 95% CI, 1.69-21.14; P = 0.005) and academic affiliation (OR, 4.50; 95% CI, 1.21-16.46; P = 0.02) were associated with report of delivery of physical activity to high-severity patients.

CONCLUSIONS

Nurse managers at three-fourths (76.6%) of eligible hospitals across Washington State reported use of physical activity in patients on mechanical ventilation. Hospital-level factors including hospital volume, academic affiliation, and presence of a mobility protocol were associated with report of higher level activity and delivery of activity to high-severity patients.

Cooccurrence of and remission from general anxiety, depression, and posttraumatic stress disorder symptoms after acute lung injury: a 2-year longitudinal study

OBJECTIVE

To evaluate the cooccurrence, and predictors of remission, of general anxiety, depression, and posttraumatic stress disorder symptoms during 2-year follow-up in survivors of acute lung injury treated in an ICU.

DESIGN

Prospective cohort study, with follow-up at 3, 6, 12, and 24 months post-acute lung injury.

SETTING

Thirteen medical and surgical ICUs in four hospitals.

PATIENTS

Survivors among 520 patients with acute lung injury.

MEASUREMENTS AND MAIN RESULTS

The outcomes of interest were measured using the Hospital Anxiety and Depression Scale anxiety and depression subscales (scores ≥ 8 indicating substantial symptoms) and the Impact of Event Scale-Revised (scores ≥ 1.6 indicating substantial posttraumatic stress disorder symptoms). Of the 520 enrolled patients, 274 died before 3-month follow-up; 186 of 196 consenting survivors (95%) completed at least one Hospital Anxiety and Depression Scale and Impact of Event Scale-Revised assessment during 2-year follow-up, and most completed multiple assessments. Across follow-up time points, the prevalence of suprathreshold general anxiety, depression, and posttraumatic stress disorder symptoms ranged from 38% to 44%, 26% to 33%, and 22% to 24%, respectively; more than half of the patients had suprathreshold symptoms in at least one domain during 2-year follow-up. The majority of survivors (59%) with any suprathreshold symptoms were above threshold for two or more types of symptoms (i.e., general anxiety, depression, and/or posttraumatic stress disorder). In fact, the most common pattern involved simultaneous general anxiety, depression, and posttraumatic stress disorder symptoms. Most patients with general anxiety, depression, or posttraumatic stress disorder symptoms during 2-year follow-up had suprathreshold symptoms at 24-month (last) follow-up. Higher Short-Form-36 physical functioning domain scores at the prior visit were associated with a greater likelihood of remission from general anxiety and posttraumatic stress disorder symptoms during follow-up.

CONCLUSIONS

The majority of acute lung injury survivors had clinically significant general anxiety, depression, or posttraumatic stress disorder symptoms, and these symptoms tended to co-occur across domains. Better physical functioning during recovery predicted subsequent remission of general anxiety and posttraumatic stress disorder symptoms.

Psychiatric symptoms and acute care service utilization over the course of the year following medical-surgical ICU admission: a longitudinal investigation*

OBJECTIVE

To determine if the presence of in-hospital substantial acute stress symptoms, as well as substantial depressive or posttraumatic stress disorder symptoms at 3 months post-ICU, are associated with increased acute care service utilization over the course of the year following medical-surgical ICU admission.

DESIGN

Longitudinal cohort study.

SETTING

Academic medical center.

PATIENTS

One hundred fifty patients who are 18 years old or older admitted to medical-surgical ICUs for over 24 hours.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Participants were interviewed in-hospital to ascertain substantial acute stress symptoms using the Posttraumatic Stress Disorder Checklist-Civilian version. Substantial depressive and posttraumatic stress disorder symptoms were assessed using the Patient Health Questionnaire-9 and the Posttraumatic Stress Disorder Checklist-Civilian version, respectively, at 3 months post-ICU. The number of rehospitalizations and emergency department visits were ascertained at 3 and 12 months post-ICU using the Cornell Services Index. After adjusting for participant and clinical characteristics, in-hospital substantial acute stress symptoms were independently associated with greater risk of an additional hospitalization (relative risk, 3.00; 95% CI, 1.80-4.99) over the year post-ICU. Substantial posttraumatic stress disorder symptoms at 3 months post-ICU were independently associated with greater risk of an additional emergency department visit during the subsequent 9 months (relative risk, 2.29; 95% CI, 1.09-4.84) even after adjusting for both rehospitalizations and emergency department visits between the index hospitalization and 3 months post-ICU.

CONCLUSIONS

Post-ICU psychiatric morbidity is associated with increased acute care service utilization during the year after a medical-surgical ICU admission. Early interventions for at-risk ICU survivors may improve long-term outcomes and reduce subsequent acute care utilization.

Physical and cognitive performance of patients with acute lung injury 1 year after initial trophic versus full enteral feeding. EDEN trial follow-up

RATIONALE

We hypothesized that providing patients with acute lung injury two different protein/calorie nutritional strategies in the intensive care unit may affect longer-term physical and cognitive performance.

OBJECTIVES

To assess physical and cognitive performance 6 and 12 months after acute lung injury, and to evaluate the effect of trophic versus full enteral feeding, provided for the first 6 days of mechanical ventilation, on 6-minute-walk distance, cognitive impairment, and secondary outcomes.

METHODS

A prospective, longitudinal ancillary study of the ARDS Network EDEN trial evaluating 174 consecutive survivors from 5 of 12 centers. Blinded assessments of patients' arm anthropometrics, strength, pulmonary function, 6-minute-walk distance, and cognitive status (executive function, language, memory, verbal reasoning/concept formation, and attention) were performed.

MEASUREMENTS AND MAIN RESULTS

At 6 and 12 months, respectively, the mean (SD) percent predicted for 6-minute-walk distance was 64% (22%) and 66% (25%) (P = 0.011 for difference between assessments), and 36 and 25% of survivors had cognitive impairment (P = 0.001). Patients performed below predicted values for secondary physical tests with small improvement from 6 to 12 months. There was no significant effect of initial trophic versus full feeding for the first 6 days after randomization on survivors' percent predicted for 6-minute-walk distance, cognitive impairment status, and all secondary outcomes.

CONCLUSIONS

EDEN trial survivors performed below predicted values for physical and cognitive performance at 6 and 12 months, with some improvement over time. Initial trophic versus full enteral feeding for the first 6 days after randomization did not affect physical and cognitive performance.

Symptoms of depression in survivors of severe sepsis: a prospective cohort study of older Americans

OBJECTIVES

To examine if incident severe sepsis is associated with increased risk of subsequent depressive symptoms and to assess which patient characteristics are associated with increased risk of depressive symptoms.

DESIGN

Prospective longitudinal cohort study.

SETTING

Population-based cohort of older U.S. adults interviewed as part of the Health and Retirement Study (1998-2006).

PARTICIPANTS

A total of 439 patients who survived 471 hospitalizations for severe sepsis and completed at least one follow-up interview.

MEASUREMENTS

Depressive symptoms were assessed with a modified version of the Center for Epidemiologic Studies Depression Scale. Severe sepsis was identified using a validated algorithm in Medicare claims.

RESULTS

The point prevalence of substantial depressive symptoms was 28% at a median of 1.2 years before sepsis, and remained 28% at a median of 0.9 years after sepsis. Neither incident severe sepsis (relative risk [RR]: 1.00; 95% confidence interval [CI]: 0.73, 1.34) nor severe sepsis-related clinical characteristics were significantly associated with subsequent depressive symptoms. These results were robust to potential threats from missing data or alternative outcome definitions. After adjustment, presepsis substantial depressive symptoms (RR: 2.20; 95% CI: 1.66, 2.90) and worse postsepsis functional impairment (RR: 1.08 per new limitation; 95% CI: 1.03, 1.13) were independently associated with substantial depressive symptoms after sepsis.

CONCLUSIONS

The prevalence of substantial depressive symptoms in severe sepsis survivors is high but is not increased relative to their presepsis levels. Identifying this large subset of severe sepsis survivors at increased risk for major depression, and beginning interventions before hospital discharge, may improve outcomes.

A longitudinal investigation of posttraumatic stress and depressive symptoms over the course of the year following medical-surgical intensive care unit admission

OBJECTIVE

The objective was to identify risk factors for posttraumatic stress disorder (PTSD) and depressive symptoms after medical-surgical intensive care unit (ICU) admission.

METHOD

This longitudinal investigation included 150 medical-surgical ICU patients. We assessed acute stress and post-ICU PTSD symptoms with the PTSD Checklist-Civilian Version and post-ICU depressive symptoms with the Patient Health Questionnaire-9. Mixed-model linear regression ascertained associations between patient and clinical characteristics and repeated measures of post-ICU PTSD and depressive symptoms.

RESULTS

The prevalences of substantial PTSD and depressive symptoms were 16% and 31% at 3 months post-ICU and 15% and 17% at 12 months post-ICU, respectively. In-hospital substantial acute stress symptoms [beta: 16.9, 95% confidence Interval (CI): 11.4, 22.4] were independently associated with increased post-ICU PTSD symptoms. Lifetime history of major depression (beta: 2.2, 95% CI: 0.1, 4.2), greater prior trauma exposure (beta: 0.5, 95% CI: 0.2, 0.9) and in-hospital substantial acute stress symptoms (beta: 3.5, 95% CI: 0.8, 6.2) were independently associated with increased post-ICU depressive symptoms.

CONCLUSIONS

In-hospital acute stress symptoms may represent a modifiable risk factor for psychiatric morbidity in ICU survivors. Early interventions for at-risk ICU survivors may improve longer-term psychiatric outcomes.

One year outcomes in patients with acute lung injury randomised to initial trophic or full enteral feeding: prospective follow-up of EDEN randomised trial

OBJECTIVE

To evaluate the effect of initial low energy permissive underfeeding ("trophic feeding") versus full energy enteral feeding ("full feeding") on physical function and secondary outcomes in patients with acute lung injury.

DESIGN

Prospective longitudinal follow-up evaluation of the NHLBI ARDS Clinical Trials Network's EDEN trial

SETTING

41hospitals in the United States.

PARTICIPANTS

525 patients with acute lung injury.

INTERVENTIONS

Randomised assignment to trophic or full feeding for up to six days; thereafter, all patients still receiving mechanical ventilation received full feeding.

MEASUREMENTS

Blinded assessment of the age and sex adjusted physical function domain of the SF-36 instrument at 12 months after acute lung injury. Secondary outcome measures included survival; physical, psychological, and cognitive functioning; quality of life; and employment status at six and 12 months.

RESULTS

After acute lung injury, patients had substantial physical, psychological, and cognitive impairments, reduced quality of life, and impaired return to work. Initial trophic versus full feeding did not affect mean SF-36 physical function at 12 months (55 (SD 33) v 55 (31), P=0.54), survival to 12 months (65% v 63%, P=0.63), or nearly all of the secondary outcomes.

CONCLUSION

In survivors of acute lung injury, there was no difference in physical function, survival, or multiple secondary outcomes at 6 and 12 month follow-up after initial trophic or full enteral feeding.
