Music intervention in the Acute and Critical Care Settings: Commentary on “The Effect of Music during Bronchoscopy: A Meta-Analysis”

The article by Tam and colleagues published in this edition of Heart & Lung, succinctly reports on the meta-analysis of research findings testing music as an adjunctive intervention during bronchoscopy. The article provides a coherent summary of the pooled evidence of music’s beneficial effect on physiological indicators of relaxation and anxiety as evidenced by reductions in heart rate and blood pressure. We offer here a commentary on the article and music intervention, including key considerations for the implementation of music in practice settings

Tailoring a Treatment Fidelity Framework for an Intensive Care Unit Clinical Trial

Background: Treatment fidelity (TF) refers to methodological strategies and practices used to monitor and enhance the reliability and validity of behavioral interventions. Treatment fidelity monitoring enhances internal and external validity and is needed for study replication and generalizability. Objectives: The aim of this study was to describe the implementation, monitoring, and impact of TF in an intensive-care-unit-based clinical trial testing music for anxiety self-management with mechanically ventilated patients. Method: Development of the criteria was based on the Five-Component Treatment Fidelity Framework from the Treatment Fidelity Workgroup. Descriptive statistics were used to evaluate adherence rates to the key TF criteria and the reasons criteria were unmet. Descriptive and nonparametric statistics were used to evaluate the impact of TF on participants\u27 use of the assigned intervention. Results: The Treatment Fidelity Framework was adapted easily to fit the study interventions. After the initial implementation phase of monitoring, adherence to key criteria was maintained at the targeted level of 80%. The majority of barriers to adherence affected the research nurses\u27 opportunity to interact with the participant and encourage use of the intervention. There was a trend toward increased use of equipment associated with the assigned condition after the initiation of TF; however, this difference was not statistically significant. Discussion: Treatment fidelity monitoring is an iterative process that requires ongoing vigilance. Identification of barriers and the implementation of methods to enhance protocol adherence are needed to enhance the reliability, validity, and generalizability of clinical trials in the dynamic and challenging research environment of the intensive care unit

Sedation is tricky : A qualitative content analysis of nurses\u27 perceptions of sedation administration in mechanically ventilated intensive care unit patients

Introduction Critical care nurses are responsible for administering sedative medications to mechanically ventilated patients. With significant advancements in the understanding of the impact of sedative exposure on physiological and psychological outcomes of ventilated patients, updated practice guidelines for assessment and management of pain, agitation, and delirium in the intensive care unit were released in 2013. The primary aim of this qualitative study was to identify and describe themes derived from critical care nurses\u27 comments regarding sedation administration practices with mechanically ventilated patients. Methods This is a qualitative content analysis of secondary text data captured through a national electronic survey of members of the American Association of Critical-Care Nurses. A subsample (n = 67) of nurses responded to a single, open-ended item at the end of a survey that evaluated nurses\u27 perceptions of current sedation administration practices. Findings Multiple factors guided sedation administration practices, including individual patient needs, nurses\u27 synthesis of clinical evidence, application of best practices, and various personal and professional practice perspectives. Our results also indicated nurses desire additional resources to improve their sedation administration practices including more training, better communication tools, and adequate staffing. Conclusions Critical care nurses endorse recommendations to minimise sedation administration when possible, but a variety of factors, including personal perspectives, impact sedation administration in the intensive care unit and need to be considered. Critical care nurses continue to encounter numerous challenges when assessing and managing sedation of mechanically ventilated patients

Factors Influencing Nurse Sedation Practices with Mechanically Ventilated Patients: A U.S. National Survey

Objectives Mechanically ventilated patients commonly receive sedative medications. There is increasing evidence that sedative medications impact on patient outcomes. Nursing behaviour is a key determinant of sedation administration. The purpose of this study was to determine factors that influence nurse sedation administration to mechanically ventilated patients. Methods The Nurse Sedation Practices Scale was mailed to a random sample of 1250 members of the American Association of Critical Care Nurses. Results A response rate of 39% was obtained. Respondents were primarily staff nurses (73%) with a bachelor\u27s degree in nursing (59%) from various intensive care unit (ICU) settings. We limited the analysis to adult ICU practitioners (n = 423). The majority of nurses (81%) agreed that sedation is necessary for patient comfort. Nurse attitudes towards the efficacy of sedation for mechanically ventilated patients was positively correlated with nurses’ report of their sedation practice ( = .28, p \u3c .001) and their intent to administer sedation ( = .58, p \u3c .001). Attitudes did not vary with respect to individual or practice setting characteristics. Conclusion Nurses’ attitudes impact sedation administration practices. Modifying nurses’ attitudes on sedation and the experience of mechanical ventilation may be necessary to change sedation practices with mechanically ventilated patients

Effects of Patient-Directed Music Intervention on Anxiety and Sedative Exposure in Critically Ill Patients Receiving Mechanical Ventilatory Support: A Randomized Clinical Trial

Importance: Alternatives to sedative medications, such as music, may alleviate the anxiety associated with ventilatory support. Objective: To test whether listening to self-initiated patient-directed music (PDM) can reduce anxiety and sedative exposure during ventilatory support in critically ill patients. Design, Setting, and Patients: Randomized clinical trial that enrolled 373 patients from 12 intensive care units (ICUs) at 5 hospitals in the Minneapolis-St Paul, Minnesota, area receiving acute mechanical ventilatory support for respiratory failure between September 2006 and March 2011. Of the patients included in the study, 86% were white, 52% were female, and the mean (SD) age was 59 (14) years. The patients had a mean (SD) Acute Physiology, Age and Chronic Health Evaluation III score of 63 (21.6) and a mean (SD) of 5.7 (6.4) study days. Interventions: Self-initiated PDM (n = 126) with preferred selections tailored by a music therapist whenever desired while receiving ventilatory support, self-initiated use of noise-canceling headphones (NCH; n = 122), or usual care (n = 125). Main Outcomes and Measures: Daily assessments of anxiety (on 100-mm visual analog scale) and 2 aggregate measures of sedative exposure (intensity and frequency). Results: Patients in the PDM group listened to music for a mean (SD) of 79.8 (126) (median [range], 12 [0-796]) minutes/day. Patients in the NCH group wore the noise-abating headphones for a mean (SD) of 34.0 (89.6) (median [range], 0 [0-916]) minutes/day. The mixed-models analysis showed that at any time point, patients in the PDM group had an anxiety score that was 19.5 points lower (95% CI, −32.2 to −6.8) than patients in the usual care group (P = .003). By the fifth study day, anxiety was reduced by 36.5% in PDM patients. The treatment × time interaction showed that PDM significantly reduced both measures of sedative exposure. Compared with usual care, the PDM group had reduced sedation intensity by −0.18 (95% CI, −0.36 to −0.004) points/day (P = .05) and had reduced frequency by −0.21 (95% CI, −0.37 to −0.05) points/day (P = .01). The PDM group had reduced sedation frequency by −0.18 (95% CI, −0.36 to −0.004) points/day vs the NCH group (P = .04). By the fifth study day, the PDM patients received 2 fewer sedative doses (reduction of 38%) and had a reduction of 36% in sedation intensity. Conclusions and Relevance: Among ICU patients receiving acute ventilatory support for respiratory failure, PDM resulted in greater reduction in anxiety compared with usual care, but not compared with NCH. Concurrently, PDM resulted in greater reduction in sedation frequency compared with usual care or NCH, and greater reduction in sedation intensity compared with usual care, but not compared with NCH. Trial Registration: clinicaltrials.gov Identifier: NCT00440700 Critically ill mechanically ventilated patients receive intravenous sedative and analgesic medications to reduce anxiety and promote comfort and ventilator synchrony. These potent medications are often administered at high doses for prolonged periods and are associated with adverse effects such as bradycardia, hypotension, gut dysmotility, immobility, weakness, and delirium.1-3 Despite protocols and sedation assessment tools that guide clinicians, patients still experience significant levels of anxiety.4,5 Unrelieved anxiety and fear are not only unpleasant symptoms that clinicians want to palliate, but increased sympathetic nervous system activity can cause dyspnea and increased myocardial oxygen demand.6 Sustained anxiety and sympathetic nervous system activation can decrease the ability to concentrate, rest, or relax.6,7 Mechanically ventilated patients have little control over pharmacological interventions to relieve anxiety; dosing and frequency of sedative and analgesic medications are controlled by intensive care unit (ICU) clinicians. Interventions are needed that reduce anxiety, actively involve patients, and minimize the use of sedative medications. Nonpharmacological interventions such as relaxing music are effective in reducing anxiety while reducing medication administration.8,9 Music is a powerful distractor that can alter perceived levels of anxiety10 by occupying attention channels in the brain with meaningful, auditory stimuli11 rather than stressful environmental stimuli. Listening to preferred, relaxing music has reduced anxiety in mechanically ventilated patients in limited trials.12-15 It is not known if music can reduce anxiety throughout the course of ventilatory support, or reduce exposure to sedative medications. We evaluated if a patient-directed music (PDM) intervention could reduce anxiety and sedative exposure in ICU patients receiving mechanical ventilation

Economic evaluation of a patient-directed music intervention for ICU patients receiving mechanical ventilatory support

Objectives: Music intervention has been shown to reduce anxiety and sedative exposure among mechanically ventilated patients. Whether music intervention reduces ICU costs is not known. The aim of this study was to examine ICU costs for patients receiving a patient-directed music intervention compared with patients who received usual ICU care. Design: A cost-effectiveness analysis from the hospital perspective was conducted to determine if patient-directed music intervention was cost-effective in improving patient-reported anxiety. Cost savings were also evaluated. One-way and probabilistic sensitivity analyses determined the influence of input variation on the cost-effectiveness. Setting: Midwestern ICUs. Patients: Adult ICU patients from a parent clinical trial receiving mechanical ventilatory support. Interventions: Patients receiving the experimental patient-directed music intervention received a MP3 player, noise-canceling headphones, and music tailored to individual preferences by a music therapist. Measurements and Main Results: The base case cost-effectiveness analysis estimated patient-directed music intervention reduced anxiety by 19 points on the Visual Analogue Scale-Anxiety with a reduction in cost of $2,322/patient compared with usual ICU care, resulting in patient-directed music dominance. The probabilistic cost-effectiveness analysis found that average patient-directed music intervention costs were$2,155 less than usual ICU care and projected that cost saving is achieved in 70% of 1,000 iterations. Based on break-even analyses, cost saving is achieved if the per-patient cost of patient-directed music intervention remains below $2,651, a value eight times the base case of$329. Conclusions: Patient-directed music intervention is cost-effective for reducing anxiety in mechanically ventilated ICU patients

Effects of music intervention on inflammatory markers in critically ill and post-operative patients: A systematic review of the literature

BACKGROUND: Music listening has been shown to reduce anxiety, stress, and patient tolerance of procedures. Music may also have beneficial effects on inflammatory biomarkers in intensive care and post-operative patients, but the quality of evidence is not clear. OBJECTIVES: We conducted a systematic review to evaluate the effects of music on inflammatory biomarkers in intensive care, and post-operative patients. METHODS: A comprehensive search of the literature was performed. After screening 1570 references, full text review of 26 studies was performed. Fourteen studies were selected for inclusion. RESULTS: Seven studies showed a significant decrease in cortisol levels, but the level of evidence was low. Three studies had low risk of methodological bias, while 11 studies had high risk of bias. CONCLUSIONS: Music intervention may decrease cortisol levels, but other biomarkers remain unchanged. Given the low level of evidence, further research on music effects on inflammatory biomarkers is needed

The CAM-ICU-7 Delirium Severity Scale: A Novel Delirium Severity Instrument for Use in the Intensive Care Unit

OBJECTIVES: Delirium severity is independently associated with longer hospital stays, nursing home placement, and death in patients outside the ICU. Delirium severity in the ICU is not routinely measured because the available instruments are difficult to complete in critically ill patients. We designed our study to assess the reliability and validity of a new ICU delirium severity tool, the Confusion Assessment Method for the ICU-7 delirium severity scale. DESIGN: Observational cohort study. SETTING: Medical, surgical, and progressive ICUs of three academic hospitals. PATIENTS: Five hundred eighteen adult (≥ 18 yr) patients. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Patients received the Confusion Assessment Method for the ICU, Richmond Agitation-Sedation Scale, and Delirium Rating Scale-Revised-98 assessments. A 7-point scale (0-7) was derived from responses to the Confusion Assessment Method for the ICU and Richmond Agitation-Sedation Scale items. Confusion Assessment Method for the ICU-7 showed high internal consistency (Cronbach's α = 0.85) and good correlation with Delirium Rating Scale-Revised-98 scores (correlation coefficient = 0.64). Known-groups validity was supported by the separation of mechanically ventilated and nonventilated assessments. Median Confusion Assessment Method for the ICU-7 scores demonstrated good predictive validity with higher odds (odds ratio = 1.47; 95% CI = 1.30-1.66) of in-hospital mortality and lower odds (odds ratio = 0.8; 95% CI = 0.72-0.9) of being discharged home after adjusting for age, race, gender, severity of illness, and chronic comorbidities. Higher Confusion Assessment Method for the ICU-7 scores were also associated with increased length of ICU stay (p = 0.001). CONCLUSIONS: Our results suggest that Confusion Assessment Method for the ICU-7 is a valid and reliable delirium severity measure among ICU patients. Further research comparing it to other delirium severity measures, its use in delirium efficacy trials, and real-life implementation is needed to determine its role in research and clinical practice
