Animal-Assisted Activity in Critically Ill Older Adults: A Randomized Pilot and Feasibility Trial.

BACKGROUND: Limited evidence suggests the efficacy of animal-assisted activities (AAA) in improving biobehavioral stress responses in older patients in intensive care units (ICUs). OBJECTIVES: To assess the feasibility of an AAA (dog) intervention for improving biobehavioral stress response, measured by self-reported stress and anxiety and salivary cortisol, C-reactive protein, and interleukin-1ß in older ICU patients, we examined enrollment, attrition, completion, data collection, and biobehavioral stress responses. METHODS: ICU patients ≥60 years old were randomly assigned to a 10-min AAA intervention or control/usual ICU care. Attitudes toward pets were assessed before the intervention. Self-reported stress and anxiety and salivary stress biomarkers were collected before and after the intervention and the usual care condition. RESULTS: The majority of patients were ineligible due to lack of decisional capacity, younger age, inability to provide saliva specimens, or critical illness. Though 15 participants were randomly allocated (AAA = 9; control = 6), only 10 completed the study. All participants completed the questionnaires; however, saliva specimens were significantly limited by volume. AAA was associated with decreases in stress and anxiety. Biomarker results were variable and revealed no specific trends associated with stress responses. Conclusions: Barriers to recruitment included an insufficient number of patients eligible for AAA based on hospital policy, difficulty finding patients who met study eligibility criteria, and illness-related factors. Recommendations for future studies include larger samples, a stronger control intervention such as a visitor without a dog, greater control over the AAA intervention, and use of blood from indwelling catheters for biomarkers.

Cranial Electrotherapy Stimulation for the Management of Depression, Anxiety, Sleep Disturbance, and Pain in Patients With Advanced Cancer: A Preliminary Study.

CONTEXT: Cranial electrotherapy stimulation (CES) is a safe modulation of brain activity for treating depression, anxiety, insomnia, and pain. However, there are no published studies in patients with advanced cancer (ACPs). OBJECTIVES: The aim of the study was to determine the feasibility and preliminary efficacy of a four-week CES intervention on depression, anxiety, sleep disturbance, and pain scores. Concurrent salivary biomarker studies were conducted. METHODS: In this one group open label pre- and post-intervention study with a four-week CES intervention, ACPs with one or more of four moderate intensity (≥3/10) Edmonton Symptom Assessment Scale (ESAS) symptoms (depression, anxiety, sleep disturbance, and pain) were eligible. Adherence (0%-100%), satisfaction rates (0-10), and safety were assessed. ESAS, Hospital Anxiety and Depression Scale (HADS), Pittsburgh Sleep Quality Index, Brief Pain Inventory, and salivary levels (cortisol, alpha amylase, C-reactive protein, and interleukin-1ß, and interleukin-6) were assessed from baseline to Week 4. RESULTS: Thirty-three of 36 patients (92%) completed the CES. Median (interquartile range) adherence CES use and satisfaction scores were 93% (89-100) and 10% (9-10), respectively, and the adherence criteria was met in the study. CES use was safe (no Grade 3 or higher adverse events). HADS anxiety (P < 0.001), HADS depression (P = 0.024), ESAS anxiety (P = 0.001), ESAS depression (P = 0.025), Brief Pain Inventory pain (P = 0.013), Pittsburgh Sleep Quality Index daytime dysfunction (P = 0.002), and medication use (P = 0.006) scores improved after four-week CES treatment. CONCLUSION: In this preliminary study, we found that the use of CES was safe and feasible in ACP. The use of CES was associated with significant improvement of depression, anxiety, pain, and sleep scores. These findings support further studies of CES in ACP for symptom control.

Effects of Animal-assisted Activities on Biobehavioral Stress Responses in Hospitalized Children: A Randomized Controlled Study.

PURPOSE: This study assessed the effectiveness of animal-assisted activities (AAA) on biobehavioral stress responses (anxiety, positive and negative affect, and salivary cortisol and C-reactive protein [CRP] levels) in hospitalized children. DESIGN AND METHODS: This was a randomized, controlled study. METHOD: Forty-eight participants were randomly assigned to receive a 10-minute AAA (n=24) or a control condition (n=24). Anxiety, positive and negative affect, and levels of salivary biomarkers were assessed before and after the intervention. RESULTS: Although increases in positive affect and decreases in negative affect were larger in the AAA condition, pre- and post-intervention differences between the AAA and control conditions were not significant. In addition, pre- and post-intervention differences between the conditions in salivary cortisol and CRP were not statistically significant. Baseline levels of anxiety, cortisol, and CRP had a significant and large correlation to the corresponding post-intervention measures. Scores on the Pet Attitude Scale were high but were not associated with changes in anxiety, positive affect, negative affect, or stress biomarkers. CONCLUSIONS: Although changes were in the expected direction, the magnitude of the effect was small. Future randomized controlled trials with larger recruitment are needed to determine the effectiveness of AAAs in reducing biobehavioral stress responses in hospitalized children. PRACTICE IMPLICATIONS: Nurses are positioned to recommend AAA as a beneficial and safe experience for hospitalized children.

Cardiovascular impact of manual and automated turns in ICU.

Mechanically ventilated patients in the intensive care unit (ICU) are typically turned manually by nursing staff to reduce the risk of developing ventilator associated pneumonia and other problems in the lungs. However, turning can induce changes in the heart rate and blood pressure that can at times have a destabilizing effect. We report here on the early stage of a study that has been undertaken to measure the cardiovascular impact of manual turning, and compare it to changes induced when patients lie on automated beds that turn continuously. Heart rate and blood pressure data were analyzed over ensembles of turns with autoregressive models for comparing baseline level to the dynamic response. Manual turning stimulated a response in the heart rate that lasted for a median of 20 minutes and was of magnitude 5 to 13 bpm. The corresponding response in mean arterial pressure was 11 to 19 mm Hg, lasting for 8 to 21 minutes. There was no discernible response of either variable to automated turns.
