Instituting a music listening intervention for critically ill patients receiving mechanical ventilation: Exemplars from two patient cases

Development of the compliance with mechanical ventilator scale in: A validity and reliability study

BACKGROUND

Mechanical ventilation is a widely used treatment modality in cardiac surgery intensive care units (ICUs), especially for patients requiring respiratory support during postoperative management.

AIM

The aim of this study was to define the process of developing a scale to assess adherence to mechanical ventilation in cardiac surgery patients and to assess the validity and reliability of the scale.

STUDY DESIGN

This is a scale development and scale validation study. The study was conducted with 222 patients between April and September 2023. In the first stage, face-to-face interviews were conducted with seven nurses. Based on the literature review and content analysis of the interviews, the researchers created an item pool. In the second stage, the validity and reliability of the Mechanical Ventilator Compliance Scale in cardiac surgery patients were assessed. The scale was developed to be used by nurses working in cardiac surgery ICUs.

RESULTS

The first 36-item scale was subjected to content validity assessment by 14 experts. It was revised according to the experts' feedback and a content validity criterion of 0.83 was obtained. Confirmatory factor analysis showed good fit values for the scale (χ2/SD = 3.09, GFI = 0.90, AGFI = 0.90, CFI = 0.91, RMSEA = 0.06, and RMR = 0.07). Test-retest analysis to assess the reliability of the scale showed good agreement between responses over time (ICC: 0.932; p < .001). Cronbach's alpha values for the scale and its subscales, behavioural and physical responses were 0.956, 0.949 and 0.912, respectively.

CONCLUSIONS

The study findings indicate that the scale is a reliable and valid tool for assessing mechanical ventilator compliance in cardiac surgery patients.

RELEVANCE FOR CLINICAL PRACTICE

This study provides nurses in cardiac surgery intensive care units with a measurement tool to objectively assess patients' compliance with mechanical ventilation therapy. The scale provides more reliable results by preventing subjective judgement and estimation in patient assessment.

Personalized music for cognitive and psychological symptom management during mechanical ventilation in critical care: A qualitative analysis

INTRODUCTION

Patients experience high symptom burden during critical care hospitalization and mechanical ventilation. Medications are of limited effectiveness and are associated with increased morbidity such as delirium and long-term cognitive and psychological impairments. Music-based interventions have been used for pain and anxiety management in critical care but remain understudied in terms of music selection and range of symptoms. This study aimed to describe the ways in which a diverse sample of critically ill adults used personalized music listening and their perceptions of the effects of music listening on symptom experience after critical injury.

METHODS

Semi-structured interviews (N = 14) of adult patients, families and friends who were provided with personalized music in an urban, academic, neurotrauma intensive care unit were collected and analyzed with grounded theory methodology. Open coding of transcripts, field notes and memos was performed using Atlas.ti.9.1. Recruitment and data collection were deemed complete once thematic saturation was achieved.

RESULTS

We identified 6 uses of personalized music listening in critical care: 1) Restoring consciousness; 2) Maintaining cognition; 3) Humanizing the hospital experience; 4) Providing a source of connection; 5) Improving psychological wellbeing; and 6) Resolving the problems of silence. Patients used music to address psychological experiences of loneliness, fear, confusion, and loss of control. Personalized music helped patients maintain their identity and process their trauma. Additional benefits of music included experiencing pleasure, hope, resilience, and feelings of normalcy. Patients disliked being sedated and used music to wake up. Findings also highlighted the problem of the lack of meaningful stimulation in critical care.

CONCLUSION

Critically injured adults used personalized music to achieve psychological and cognitive homeostasis during critical care hospitalization. These results can inform future studies designed to explore the use of music-based interventions to prevent and treat the cognitive and emotional morbidity of critical care.

Music-Based Interventions for Symptom Management in Critically Ill, Mechanically Ventilated Adults: A Scoping Review of the Literature

Background: Patients in intensive care units experience high symptom burden during mechanical ventilation (MV). Pharmacologic symptom management is associated with side effects and increased morbidity. Music-based interventions (MBIs) have been associated with reductions in both anxiety in MV adults and pain for critically ill adults, yet their use for the management of other burdensome symptoms has not been evaluated. The purpose of this scoping review is to map the state of evidence for the use of prerecorded music listening MBIs for symptom management in MV adults. Methods: A systematic search of the literature was conducted across four electronic databases (PubMed, EMBASE, CINAHL, and Web of Science) for experimental designed studies that measured the efficacy of MBIs for the management of physical and psychological symptoms including anxiety, sedation/agitation, dyspnea, distress, delirium, sleep, stress, fear, loneliness, or depression in critically ill, MV adults between January 1, 1998, and April 18, 2023. Results: A total of 643 abstracts and 29 clinical trials were included. Overall, the risk of bias, assessed using the Evidence Project tool, was moderate. MBIs were mostly delivered with headphones using music selected either by investigators or from a limited selection. MBIs were associated with reduced pain, agitation, dyspnea, distress and anxiety, and improved tolerance of MV and sedative weaning. Outcomes of delirium were mixed. No studies explored sleep disturbances, fear, or loneliness. Conclusions: Use of MBIs improved symptom experience for critically ill adults during MV. Future studies employing unrestricted patient-preferred music selections and exploring outcomes of sleep quality, psychological distress, and delirium are needed in this highly symptomatic patient population.

Feasibility & Acceptability of Patient and Family Directed Active Music Making during Pediatric Bone Marrow Transplant Process

(1) Background: Bone marrow transplant (BMT) is an aggressive and complex medical treatment for children with certain types of cancer and other diseases. The transplant process entails replacing the patient's diseased bone marrow with the healthy marrow of a donor. During the course of treatment, patients are isolated in their room to reduce the risk of infection. Patient's experience a variety of symptoms and side effects during the process including nausea, vomiting, diarrhea, mouth sores, fatigue, pain, discomfort, extreme muscle weakness, and emotional distress. Children often need a parent or caregiver present with them at all times throughout treatment. This process can cause significant stress and anxiety for the patient and their family. (2) Methods: This study explored the feasibility and acceptability of a patient and family directed active music making protocol during the BMT process. Ten patients, their parents, and family members participated in the study during the course of the BMT. (3) Results: Participants reported engaging in active music making 3-4 times per week and completed 121 journal forms reporting their music making experiences. They indicated using active music making to manage pain, discomfort, stress, anxiety, and boredom, foster relaxation and sleep, for enjoyment, and as a way to connect. (4) Conclusions: Patients, parents and family members reported feeling a sense of empowerment when engaged in making music to support their child or loved one.

The Use of Music to Manage Burnout in Nurses: A Systematic Review

OBJECTIVE

There is a high prevalence of burnout in nurses. This systematic review investigates the use of music to manage burnout in nurses.

DATA SOURCE

MEDLINE (Ovid), MEDLINE InProcess/ePubs, Embase, APA PsycINFO, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov databases were searched.

STUDY INCLUSION AND EXCLUSION CRITERIA

Full-text articles were selected if the study assessed the use of music to manage burnout in nurses. Burnout was defined according to the International Classification of Diseases 11th Revision.

DATA EXTRACTION

Data were extracted using an Excel sheet. The second and third authors independently extracted study characteristics, frequency and type of music engagement, measures of burnout, and burnout outcomes (occupational stress, coping with stress, and related symptoms such as anxiety).

DATA SYNTHESIS

Study and outcome data were summarized.

RESULTS

The literature search resulted in 2210 articles and 16 articles were included (n = 1205 nurses). All seven cross-sectional studies reported upon nurses' self-facilitated use of music including music listening, playing instruments, and music entertainment for coping or preventing stress, supporting wellbeing, or enhancing work engagement. Externally-facilitated music engagement, including music listening, chanting, percussive improvisation, and song writing, was reported in the four randomized controlled trials and five cohort studies with reductions in burnout outcomes.

CONCLUSIONS

Self-facilitated and externally-facilitated music engagement can help to reduce burnout in nurses.

Feasibility and Acceptability of Music Imagery and Listening Interventions for Analgesia: Protocol for a Randomized Controlled Trial

Background

Chronic pain and access to care are identified as critical needs of the Veterans Health Administration. Music imagery and music listening interventions have shown promise as effective nonpharmacological options for pain management. However, most studies have focused on acute pain, passive music experiences, and in-person delivery.

Objective

In this study, we aimed to examine the feasibility and acceptability of 2 music interventions delivered through telehealth for chronic musculoskeletal pain, trial design, and theoretical model before conducting a fully powered efficacy or comparative effectiveness trial.

Methods

FAMILIA (Feasibility and Acceptability of Music Imagery and Listening Interventions for Analgesia) is a 3-arm, parallel group, pilot trial. A total of 60 veterans will be randomized to one of the three conditions: music imagery, music listening, or usual care. Aim 1 is to test the feasibility and acceptability of a multicomponent, interactive music imagery intervention (8-weekly, individual sessions) and a single-component, minimally interactive music learning intervention (independent music listening). Feasibility metrics related to recruitment, retention, engagement, and completion of the treatment protocol and questionnaires will be assessed. Up to 20 qualitative interviews will be conducted to assess veteran experiences with both interventions, including perceived benefits, acceptability, barriers, and facilitators. Interview transcripts will be coded and analyzed for emergent themes. Aim 2 is to explore the effects of music imagery and music listening versus usual care on pain and associated patient-centered outcomes. These outcomes and potential mediators will be explored through changes from baseline to follow-up assessments at 1, 3, and 4 months. Descriptive statistics will be used to describe outcomes; this pilot study is not powered to detect differences in outcomes.

Results

Recruitment for FAMILIA began in March 2022, and as of July 2022, 16 participants have been enrolled. We anticipate that enrollment will be completed by May 2023. We expect that music imagery and music listening will prove acceptable to veterans and that feasibility benchmarks will be reached. We hypothesize that music imagery and music listening will be more effective than usual care on pain and related outcomes.

Conclusions

FAMILIA addresses four limitations in music intervention research for chronic pain: limited studies in veterans, evaluation of a multicomponent music intervention, methodological rigor, and internet-based delivery. Findings from FAMILIA will inform a fully powered trial to identify putative mechanisms and test efficacy.

Analysis of Preferred Music of Mechanically Ventilated Intensive Care Unit Patients Enrolled in a Randomized Controlled Trial

Objective: Music listening interventions are utilized in a wide variety of clinical settings to help patients manage stress, anxiety, pain, discomfort, as well as attendant influences on sedative exposure, delirium, and cognitive functioning. While the body of research regarding the use of music-based listening interventions continues to grow, there is a paucity of information in the literature about specific music used for listening interventions. The purpose of this secondary analysis is to examine the music that study participants identified as their preferred music and listened to during the study. Design: This secondary analysis is based on data from a parent study, which was a three-arm randomized controlled trial attesting a patient-directed music (PDM) listening protocol to manage the psychophysiological symptom of anxiety. Setting: Twelve intensive care units in a major metropolitan area in the United States. Subjects: Participants included the 126 mechanically ventilated patients enrolled and randomized to the PDM listening arm of the study. Results: Data presented in this study include playlists from the 12 genres patients self-identified as preferred with specific groups and artists requested for music listening during the study. Discographies of the playlists are also included. Conclusions: The efficacy of interventions is impacted by the design of the intervention and the selection of music utilized. Implications of this analysis further explore the role of a board-certified music therapist (MT-BC) in designing and implementing a music listening intervention. The specialized knowledge on the therapeutic use and benefits of music that an MT-BC possesses supports the development of quality study intervention and appropriate implementation. The review of the music utilized in the parent study provides detailed information about the music utilized to inform future research focused on music listening interventions to effectively build on previous studies. Clinical Trial Registration: ClinicalTrials.gov NCT00440700.

Music Use for Sedation in Critically ill Children (MUSiCC trial): study protocol for a pilot randomized controlled trial

Background

Stress induced by pain and anxiety is common in pediatric intensive care unit (PICU) patients. Sedation/analgesia in PICU is usually achieved through various analgesics and sedatives. Excessive use of these drugs can put patients at risk for hemodynamic/respiratory instability, prolonged ventilation, withdrawal, delirium, and critical illness polyneuromyopathy.

The use of non-pharmacologic interventions has been recommended by sedation guidelines. However, non-pharmacological measures in PICU, including music and noise reduction, have been inadequately studied.

Methods

The Music Use for Sedation in Critically ill Children (MUSiCC trial) pilot study is an investigator-initiated, three-arm, randomized controlled trial (RCT) on the use of music for sedation in PICU. The main goal of the study is to demonstrate feasibility of a music trial in PICU and to obtain the necessary information to plan a larger trial. The study compares music versus noise cancelation versus control in sedated and mechanically ventilated children admitted to PICU. In the music group, children receive the music (modified classical music) three times a day for 30 min at a time. Music is delivered with noise cancelation headphones. The noise cancelation group receives the same intervention but with a no music (sham playlist). The control group receives usual care with no specific intervention. Children remain in the study until extubation or a maximum of 7 days. The primary outcomes of the study are feasibility and sedation/analgesia requirements. Secondary outcomes include change in vital signs before and during the intervention, ICU delirium, and adverse effects related to the intervention. The estimated sample size is 20 subjects per group for a total of 60 children.

Discussion

Despite being recommended by current guidelines, evidence to support the use of music in PICU is lacking. Music has the potential to reduce sedation requirements and their negative side effects. This pilot RCT will demonstrate feasibility and provide the necessary information to plan a larger trial focusing on the effectiveness of the intervention.

Trial registration

The study was registered at ClinicalTrials.gov (NCT03497559) on April 13, 2018.

Effects of music interventions on stress-related outcomes: a systematic review and two meta-analyses

Music interventions are used for stress reduction in a variety of settings because of the positive effects of music listening on both physiological arousal (e.g., heart rate, blood pressure, and hormonal levels) and psychological stress experiences (e.g., restlessness, anxiety, and nervousness). To summarize the growing body of empirical research, two multilevel meta-analyses of 104 RCTs, containing 327 effect sizes and 9,617 participants, were performed to assess the strength of the effects of music interventions on both physiological and psychological stress-related outcomes, and to test the potential moderators of the intervention effects. Results showed that music interventions had an overall significant effect on stress reduction in both physiological (d = .380) and psychological (d = .545) outcomes. Further, moderator analyses showed that the type of outcome assessment moderated the effects of music interventions on stress-related outcomes. Larger effects were found on heart rate (d = .456), compared to blood pressure (d = .343) and hormone levels (d = .349). Implications for stress-reducing music interventions are discussed.

Relief of Procedural Pain in Critically Ill Patients by Music Therapy: A Randomized Controlled Trial

BACKGROUND

This study aimed to determine the effectiveness of music listening for procedural pain relief using two different observational pain tools during endotracheal suctioning.

MATERIALS AND METHODS

This study was a randomized controlled trial. The sample of the study included 98 patients with mechanical ventilation support who met the selection criteria. The patients were randomly assigned to control and music therapy groups. Patients in the control group were routinely suctioned as usual. Patients in the music group received music therapy 20 min before, during, and 20 min after endotracheal suctioning. The primary outcome was the pain relief during suctioning.

RESULTS

Forty patients in each arm completed the study. Pain scores in the Critical Care Pain Observation Tool and Behavioral Pain Scale were lower in the music group than in the control group during endotracheal suctioning (group: F = 14.85, p = 0.000; F = 9.04, p = 0.000, respectively). It was also found to be a significant interaction effect between the groups and time (group × time: F = 17.35, p = 0.000; F = 18.00, p = 0.000, respectively).

CONCLUSION

The Critical Care Pain Observation Tool and Behavioral Pain Scale in the current study generally demonstrated similar pain scores during the painful procedure. Our findings support that music therapy may act as a nonpharmacological therapy to relieve procedural pain in patients on mechanical ventilation.

Psychogenic stress in hospitalized veterinary patients: Causation, implications, and therapies

OBJECTIVE

To review the sources, adverse effects, diagnosis, treatment, and prevention of psychogenic stress in hospitalized human and veterinary patients.

DATA SOURCES

Data were collected by searching PubMed for veterinary and human literature from the past 10 years.

HUMAN DATA SYNTHESIS

Psychogenic stress has been linked to immune suppression; gastrointestinal, cardiovascular, and cutaneous diseases; delayed wound healing; alterations in pain perception; and neurologic impairment. Sources of psychogenic stress include environmental alterations such as excessive noise and light, social and physical factors, sleep disruption, drugs, and underlying disease. Nonpharmacologic options for stress reduction include environmental and treatment modifications, music therapy, and early mobilization. Pharmacologic options include sedation with benzodiazepines and dexmedetomidine. Trazodone and melatonin have been examined for use in sleep promotion but are not currently recommended as standard treatments in ICU.

VETERINARY DATA SYNTHESIS

Activation of the stress response in veterinary patients is largely the same as in people, as are the affected body systems. Possible sources of stress can include social, physical, and environmental factors. No gold standard currently exists for the identification and quantification of stress. A combination of physical examination findings and the results of serum biochemistry, CBC, and biomarker testing can be used to support the diagnosis. Stress scales can be implemented to identify stressed patients and assess severity. Nonpharmacologic treatment options include low-stress handling, pheromones, environmental modifications, and sleep promotion. Pharmacologic options include trazodone, benzodiazepines, dexmedetomidine, and melatonin.

CONCLUSION

The prevalence and clinical significance of psychogenic stress in hospitalized veterinary patients is unknown. Future studies are needed to specifically examine the causative factors of psychogenic stress and the effects of various therapies on stress reduction. The recognition and reduction of psychogenic stress in veterinary patients can lead to improvements in patient care and welfare.

IMPACT OF A VENTILATORY WEANING PROTOCOL IN AN INTENSIVE CARE UNIT FOR ADULTS

ABSTRACT Objective: to evaluate the impact of a ventilatory weaning protocol on the weaning quality and on the outcomes of the patients. Method: a quasi-experimental quantitative study, consisting of comparing a prospective study with a retrospective study. Data was collected through a weaning log sheet applied between September and December 2015 at an intensive care unit in northern Portugal following the implementation of a weaning protocol and compared with a base-line constituted in the year preceding the implementation of the ventilatory weaning protocol. Results: the experimental group had a score mean of higher overall quality of weaning, with a reduction in the timing for initiating the weaning in 27.3% and the weaning time in 36.6%. Conclusion: the implementation of the ventilatory weaning protocol improved the overall quality of the weaning, facilitating the identification of patients with criteria to initiate the process, starting earlier, resulting in a reduction in ventilatory weaning time.

Innovative Designs for the Smart ICU

Successfully designing a new ICU requires clarity of vision and purpose and the recognition that the patient room is the core of the ICU experience for patients, staff, and visitors. The ICU can be conceptualized into three components: the patient room, central areas, and universal support services. Each patient room should be designed for single patient use and be similarly configured and equipped. The design of the room should focus upon functionality, ease of use, healing, safety, infection control, communications, and connectivity. All aspects of the room, including its infrastructure; zones for work, care, and visiting; environment, medical devices, and approaches to privacy; logistics; and waste management, are important elements in the design process. Since most medical devices used at the ICU bedside are really sophisticated computers, the ICU needs to be capable of supporting the full scope of medical informatics. The patient rooms, the central ICU areas (central stations, corridors, supply rooms, pharmacy, laboratory, staff lounge, visitor waiting room, on-call suite, conference rooms, and offices), and the universal support services (infection prevention, finishings and flooring, staff communications, signage and wayfinding, security, and fire and safety) work best when fully interwoven. This coordination helps establish efficient and safe patient throughput and care and fosters physical and social cohesiveness within the ICU. A balanced approach to centralized and decentralized monitoring and logistics also offers great flexibility. Synchronization of the universal support services in the ICU with the hospital's existing systems maintains unity of purpose and continuity across the enterprise and avoids unnecessary duplication of efforts.

Comparison of the Effect of Open and Closed Endotracheal Suctioning Methods on Pain and Agitation in Medical ICU Patients: A Clinical Trial

Background

Endotracheal suctioning is a necessary procedure practiced by nurses in intensive care units to remove lung secretions. This procedure leads to higher oxygenation levels and reduced breathing difficulties. It also prevents atelectasis, pulmonary infections, and the accumulation of secretions.

Objectives

The present study aims to compare the effectiveness of open and closed endotracheal suction tube systems on pain and agitation in patients under mechanical ventilation.

Methods

A randomized controlled clinical trial was conducted in the general intensive care units of Khatam-ol-Anbia hospital and Sina hospital, Tehran, Iran, in 2015. In total, 60 patients who were qualified to be included in the study were randomly assigned to either the intervention group or the control group. When necessary, suction was carried out for each patient using the standard technique. The patients’ level of pain and agitation was measured in both groups at five stages (before, during, immediately after, 5 minutes after, and 15 minutes after the intervention) using the behavioral pain scale and the Richmond agitation sedation scale.

Results

Significant statistical differences in the pain and agitation at different times within each of the two groups were observed for both open and closed suction (P > 0.001). However, these changes at different times between the two groups was not significant (P < 0.05).

Conclusions

Although statistical differences were observed in the levels of pain and agitation in the two groups, the type of suction system did not have any effect on the level of pain and agitation of patients under mechanical ventilation. The researchers recommend that other studies with larger sample sizes should be carried out.

The impact of music therapy versus music medicine on psychological outcomes and pain in cancer patients: a mixed methods study

PURPOSE

The purpose of this study was to compare the impact of music therapy (MT) versus music medicine (MM) interventions on psychological outcomes and pain in cancer patients and to enhance understanding of patients' experiences of these two types of music interventions.

METHODS

This study employed a mixed methods intervention design in which qualitative data were embedded within a randomized cross-over trial. Thirty-one adult cancer patients participated in two sessions that involved interactive music making with a music therapist (MT) and two sessions in which they listened to pre-recorded music without the presence of a therapist (MM). Before and after each session, participants reported on their mood, anxiety, relaxation, and pain by means of visual analogue and numeric rating scales. Thirty participants completed an exit interview.

RESULTS

The quantitative data suggest that both interventions were equally effective in enhancing target outcomes. However, 77.4 % of participants expressed a preference for MT sessions. The qualitative data indicate that music improves symptom management, embodies hope for survival, and helps connect to a pre-illness self, but may also access memories of loss and trauma. MT sessions helped participants tap into inner resources such as playfulness and creativity. Interactive music making also allowed for emotional expression. Some participants preferred the familiarity and predictability of listening to pre-recorded music.

CONCLUSIONS

The findings of this study advocate for the use of music in cancer care. Treatment benefits may depend on patient characteristics such as outlook on life and readiness to explore emotions related to the cancer experience.

Music interventions for mechanically ventilated patients

BACKGROUND

Mechanical ventilation often causes major distress and anxiety in patients. The sensation of breathlessness, frequent suctioning, inability to talk, uncertainty regarding surroundings or condition, discomfort, isolation from others, and fear contribute to high levels of anxiety. Side effects of analgesia and sedation may lead to the prolongation of mechanical ventilation and, subsequently, to a longer length of hospitalization and increased cost. Therefore, non-pharmacological interventions should be considered for anxiety and stress management. Music interventions have been used to reduce anxiety and distress and improve physiological functioning in medical patients; however, their efficacy for mechanically ventilated patients needs to be evaluated. This review was originally published in 2010 and was updated in 2014.

OBJECTIVES

To update the previously published review that examined the effects of music therapy or music medicine interventions (as defined by the authors) on anxiety and other outcomes in mechanically ventilated patients. Specifically, the following objectives are addressed in this review.1. To conduct a meta-analysis to compare the effects of participation in standard care combined with music therapy or music medicine interventions with standard care alone.2. To compare the effects of patient-selected music with researcher-selected music.3. To compare the effects of different types of music interventions (e.g., music therapy versus music medicine).

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 2), MEDLINE (1950 to March 2014), CINAHL (1980 to March 2014), EMBASE (1980 to March 2014), PsycINFO (1967 to March 2014), LILACS (1982 to March 2014), Science Citation Index (1980 to March 2014), www.musictherapyworld.net (1 March 2008) (database is no longer functional), CAIRSS for Music (to March 2014), Proquest Digital Dissertations (1980 to March 2014), ClinicalTrials.gov (2000 to March 2014), Current Controlled Trials (1998 to March 2014), the National Research Register (2000 to September 2007), and NIH CRISP (all to March 2014). We handsearched music therapy journals and reference lists, and contacted relevant experts to identify unpublished manuscripts. There was no language restriction. The original search was performed in January 2010.

SELECTION CRITERIA

We included all randomized and quasi-randomized controlled trials that compared music interventions and standard care with standard care alone for mechanically ventilated patients.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted the data and assessed the methodological quality of included studies. We contacted authors to obtain missing data where needed. Where possible, results for continuous outcomes were presented in meta-analyses using mean differences and standardized mean differences. Post-test scores were used. In cases of significant baseline difference, we used change scores. For dichotomous outcomes, we presented the results as risk ratios.

MAIN RESULTS

We identified six new trials for this update. In total, the evidence for this review rests on 14 trials (805 participants). Music listening was the main intervention used, and 13 of the studies did not include a trained music therapist. Results indicated that music listening may be beneficial for anxiety reduction in mechanically ventilated patients. Specifically, music listening resulted, on average, in an anxiety reduction that was 1.11 standard deviation units greater (95% CI -1.75 to -0.47, P = 0.0006) than in the standard care group. This is considered a large and clinically significant effect. Findings indicated that listening to music consistently reduced respiratory rate and systolic blood pressure, suggesting a relaxation response. Furthermore, one large-scale study reported greater reductions in sedative and analgesic intake in the music listening group compared to the control group, and two other studies reported trends for reduction in sedative and analgesic intake for the music group. One study found significantly higher sedation scores in the music listening group compared to the control group.No strong evidence was found for reduction in diastolic blood pressure and mean arterial pressure. Furthermore, inconsistent results were found for reduction in heart rate with seven studies reporting greater heart rate reductions in the music listening group and one study a slightly greater reduction in the control group. Music listening did not improve oxygen saturation levels.Four studies examined the effects of music listening on hormone levels but the results were mixed and no conclusions could be drawn.No strong evidence was found for an effect of music listening on mortality rate but this evidence rested on only two trials.Most trials were assessed to be at high risk of bias because of lack of blinding. Blinding of outcome assessors is often impossible in music therapy and music medicine studies that use subjective outcomes, unless the music intervention is compared to another treatment intervention. Because of the high risk of bias, these results need to be interpreted with caution.No studies could be found that examined the effects of music interventions on quality of life, patient satisfaction, post-discharge outcomes, or cost-effectiveness. No adverse events were identified.

AUTHORS' CONCLUSIONS

This updated systematic review indicates that music listening may have a beneficial effect on anxiety in mechanically ventilated patients. These findings are consistent with the findings of three other Cochrane systematic reviews on the use of music interventions for anxiety reduction in medical patients. The review furthermore suggests that music listening consistently reduces respiratory rate and systolic blood pressure. Finally, results indicate a possible beneficial impact on the consumption of sedatives and analgesics. Therefore, we conclude that music interventions may provide a viable anxiety management option to mechanically ventilated patients.

Music preferences of mechanically ventilated patients participating in a randomized controlled trial

Mechanical ventilation (MV) is a life-saving measure and supportive modality utilized to treat patients experiencing respiratory failure. Patients experience pain, discomfort, and anxiety as a result of being mechanically ventilated. Music listening is a non-pharmacological intervention used to manage these psychophysiological symptoms associated with mechanical ventilation. The purpose of this secondary analysis was to examine music preferences of 107 MV patients enrolled in a randomized clinical trial that implemented a patient-directed music listening protocol to help manage the psychophysiological symptom of anxiety. Music data presented includes the music genres and instrumentation patients identified as their preferred music. Genres preferred include: classical, jazz, rock, country, and oldies. Instrumentation preferred include: piano, voice, guitar, music with nature sounds, and orchestral music. Analysis of three patients' preferred music received throughout the course of the study is illustrated to demonstrate the complexity of assessing MV patients and the need for an ongoing assessment process.

Effect of nature-based sounds' intervention on agitation, anxiety, and stress in patients under mechanical ventilator support: a randomised controlled trial

BACKGROUND

Few studies have been conducted to investigate the effect of nature-based sounds (N-BS) on agitation, anxiety level and physiological signs of stress in patients under mechanical ventilator support. Non-pharmacological nursing interventions such as N-BS can be less expensive and efficient ways to alleviate anxiety and adverse effects of sedative medications in patients under mechanical ventilator support.

OBJECTIVES

This study was conducted to identify the effect of the nature-based sounds' intervention on agitation, anxiety level and physiological stress responses in patients under mechanical ventilation support.

METHODS

A randomized placebo-controlled trial design was used to conduct this study. A total of 60 patients aged 18-65 years under mechanical ventilation support in an intensive care unit were randomly assigned to the control and experimental groups. The patients in the intervention group received 90 min of N-BS. Pleasant nature sounds were played to the patients using media players and headphones. Patients' physiological signs were taken immediately before the intervention and at the 30th, 60th, 90th minutes and 30 min after the procedure had finished. The physiological signs of stress assessed were heart rate, respiratory rate, and blood pressure. Data were collected over eight months from Oct 2011 to June 2012. Anxiety levels and agitation were assessed using the Faces Anxiety Scale and Richmond Agitation Sedation Scale, respectively.

RESULTS

The experimental group had significantly lower systolic blood pressure, diastolic blood pressure, anxiety and agitation levels than the control group. These reductions increased progressively in the 30th, 60th, 90th minutes, and 30 min after the procedure had finished indicating a cumulative dose effect.

CONCLUSIONS

N-BS can provide an effective method of decreasing potentially harmful physiological responses arising from anxiety in mechanically ventilated patients. Nurses can incorporate N-BS intervention as a non-pharmacologic intervention into the daily care of patients under mechanical ventilation support in order to reduce their stress and anxiety.
