Multinational Association of Supportive Care in Cancer (MASCC) 2020 clinical practice recommendations for the management of immune-related adverse events: pulmonary toxicity.

The immune checkpoints associated with the CTLA-4 and PD-1 pathways are critical modulators of immune activation. These pathways dampen the immune response by providing brakes on activated T cells, thereby ensuring more uniform and controlled immune reactions and avoiding immune hyper-responsiveness and autoimmunity. Cancer cells often exploit these regulatory controls through a variety of immune subversion mechanisms, which facilitate immune escape and tumor survival. Immune checkpoint inhibitors (ICI) effectively block negative regulatory signals, thereby augmenting immune attack and tumor killing. This process is a double-edged sword in which release of regulatory controls is felt to be responsible for both the therapeutic efficacy of ICI therapy and the driver of immune-related adverse events (IrAEs). These adverse immune reactions are common, typically low-grade and may affect virtually every organ system. In the early clinical trials, lung IrAEs were rarely described. However, with ever-expanding clinical applications and more complex ICI-containing regimens, lung events, in particular, pneumonitis, have become increasingly recognized. ICI-related lung injury is clinically distinct from other types of lung toxicity and may lead to death in advanced stage disease. Thus, knowledge regarding the key characteristics and optimal treatment of lung-IrAEs is critical to good outcomes. This review provides an overview of lung-IrAEs, including risk factors and epidemiology, as well as clinical, radiologic, and histopathologic features of ICI-related lung injury. Management principles for ICI-related lung injury, including current consensus on steroid refractory pneumonitis and the use of other immune modulating agents in this setting are also highlighted.

Multinational Association of Supportive Care in Cancer (MASCC) 2020 clinical practice recommendations for the management of severe gastrointestinal and hepatic toxicities from checkpoint inhibitors.

Immune-related adverse events (IrAEs) affecting the gastrointestinal (GI) tract and liver are among the most frequent and most severe inflammatory toxicities from contemporary immunotherapy. Inflammation of the colon and or small intestines (entero)colitis is the single most common GI IrAE and is an important cause of delay of discontinuation of immunotherapy. The severity of these GI IrAEs can range from manageable with symptomatic treatment alone to life-threatening complications, including perforation and liver failure. The frequency and severity of GI IrAEs is dependent on the specific immunotherapy given, with cytotoxic T lymphocyte antigen (CTLA)-4 blockade more likely to induce severe GI IrAEs than blockade of either programmed cell death protein 1 (PD-1) or PD-1 ligand (PD-L1), and combination therapy showing the highest rate of GI IrAEs, particularly in the liver. To date, we have minimal prospective data on the appropriate diagnosis and management of GI IrAEs, and recommendations are based largely on retrospective data and expert opinion. Although clinical diagnoses of GI IrAEs are common, biopsy is the gold standard for diagnosis of both immunotherapy-induced enterocolitis and hepatitis and can play an important role in excluding competing, though less common, diagnoses and ensuring optimal management. GI IrAEs typically respond to high-dose corticosteroids, though a significant fraction of patients requires secondary immune suppression. For colitis, both TNF-α blockade with infliximab and integrin inhibition with vedolizumab have proved highly effective in corticosteroid-refractory cases. Detailed guidelines have been published for the management of low-grade GI IrAEs. In the setting of more severe toxicities, involvement of a GI specialist is generally recommended. The purpose of this review is to survey the available literature and provide management recommendations focused on the GI specialist.

Multinational Association of Supportive Care in Cancer (MASCC) 2020 clinical practice recommendations for the management of severe dermatological toxicities from checkpoint inhibitors.

Immune checkpoint inhibitors (ICIs) frequently result in cutaneous immune-related adverse events (IrAEs). Although the majority of these events are mild-to-moderate in severity, up to 5% are severe, which may lead to morbidity and dose interruption or discontinuation of ICI therapy. In addition, up to 25% of dermatologic IrAEs are corticosteroid-refractory or corticosteroid-dependent. These 2020 MASCC recommendations cover the diagnosis and management of cutaneous IrAEs with a focus on moderate-to-severe and corticosteroid-resistant events. Although the usage of immune-suppressive therapy has been advocated in this setting, there is a lack of randomized clinical trial data to provide a compelling level of evidence of its therapeutic benefit.

Multinational Association of Supportive Care in Cancer (MASCC) 2020 clinical practice recommendations for the management of immune-mediated cardiovascular, rheumatic, and renal toxicities from checkpoint inhibitors.

Immune checkpoint inhibitors (ICIs) have emerged as the newest pillar of cancer treatment. Immune-mediated toxicities, stemming from increased activity within the T cell lineage, range from asymptomatic or mild complications to those that are fulminant and potentially fatal. Although they are of variable occurrence, cardiovascular, rheumatic, and renal immune-mediated toxicities are among the most serious of these adverse events. We present MASCC recommendations with respect to the workup and management of cardiovascular, rheumatic, and renal immune-mediated toxicities with a focus on presentations that require treatment with immunomodulating agents.

Multinational Association of Supportive Care in Cancer (MASCC) 2020 clinical practice recommendations for the management of immune checkpoint inhibitor endocrinopathies and the role of advanced practice providers in the management of immune-mediated toxicities.

Immune checkpoint inhibitors (ICIs) have emerged as the newest pillar of cancer treatment, transforming outcomes in melanoma and showing benefit in a range of malignancies. Immune-mediated toxicities, stemming from increased activity within the T cell lineage, range from asymptomatic or mild complications to those that are fulminant and potentially fatal. Immune-mediated endocrinopathies include hypophysitis, thyroiditis, and insulin-dependent diabetes mellitus. These presentations, which may be vague and non-specific, can be life-threatening if not diagnosed and treated appropriately. This review considers the work-up and management of immune-mediated endocrinopathies and also considers the role of advanced practice practitioners in the management of immune-mediated toxicities. These state-of-the-art MASCC recommendations represent a comprehensive overview of the management and clinical work-up in those in whom the diagnosis should be considered.

The Impact of Provider Education on Pediatric Palliative Care Referral.

INTRODUCTION: Palliative care can significantly benefit children managing a life-limiting illness; unfortunately, services are still generally reserved for end of life. The aim of this project was to demonstrate how established guidelines and provider education could impact referrals. METHODS: Educational sessions outlining national referral recommendations were offered to providers in the neonatal intensive care unit, pediatric intensive care unit, and Center for Cancer and Blood Disorders at a tertiary care facility. Presurveys and postsurveys were administered at the time of the intervention, and referral rates for the organization were collected for 2 months before and 2 months after the intervention. RESULTS: While there was a clinically significant increase in hospital-wide referral rates, most important was the statistically significant (p < .1) increase in provider comfortability with established guidelines. DISCUSSION: Palliative care is essential for optimizing quality of life. Provider knowledge of referral criteria ensures that patients receive this service early in their disease trajectory and can benefit from its inclusion within their care team.

Introduction: Role of palliative care for the surgical patient.

Palliative care (PC) seeks to improve the quality of life for patients facing serious illness. Several oncology organizations have guidelines about PC, reflecting the need to integrate PC into standard oncology care. Many surgical patients do not receive PC despite the need for these services and established surgical PC competencies. Recent educational and research efforts reveal increased appreciation of the need and benefit of integrating PC services with cancer care in general, and surgical care, specifically.

Benefits of a Nationwide Palliative Care Education Program on Lung Cancer Physicians.

Objective The early integration of palliative care into standard cancer treatment has become a global standard. The Palliative care Emphasis program on symptom management and Assessment for Continuous medical Education (PEACE) has been conducted in Japan, and previous studies have reported that the PEACE workshop was able to improve various palliative care skills of participants. However, whether or not the effects of the program are long-lasting and if the program consequently changed physicians' practice with regard to lung cancer patients have been unclear. Methods Web-based surveys, including the palliative care knowledge test (PEACE-Q), the Palliative Care self-reported Practice Scale (PCPS), and the Palliative Care Difficulties Scale (PCDS), were conducted among lung cancer physicians in Japan. The differences in the survey results between participants and non-participants of the PEACE workshop were examined. Results Among 923 respondents (455 respiratory physicians, 345 pulmonary surgeons, and 123 others), 519 had participated in the PEACE workshop. The total PEACE-Q score was significantly higher in the PEACE workshop participants than in non-participants (28.0 versus 24.5, p<0.0001). The score was significantly higher in respiratory physicians than in pulmonary surgeons (27.4 versus 25.5). The total PCPS and PCDS scores were also significantly better in workshop participants than in non-participants (71.8 versus 67.1 and 34.3 versus 36.9, respectively), although some domains of PCDS were similar between the groups. Conclusion The PEACE program improved the knowledge and practices with regard to palliative care and resolved difficulties associated therewith among lung cancer physicians. In regions where palliative care specialists are insufficient, such educational programs may be effective.

Development of Curricular Milestones for Hospice and Palliative Medicine Fellowship Training in the U.S.

CONTEXT: A physician workgroup of the American Academy of Hospice and Palliative Medicine sought to define curricular milestones (CMs) for hospice and palliative medicine (HPM) Fellowship Programs. The developed list of CMs would serve as components upon which to organize curriculum and standardize what to teach during training. These would complement entrustable professional activities previously developed by this group and new specialty-specific reporting milestones (RMs) for HPM developed through the Accreditation Council for Graduate Medical Education. OBJECTIVES: The objective of this study was to develop and vet CMs for HPM fellowships in the U.S. METHODS: A draft of CMs was developed through an iterative consensus group process with repeated cycles of drafting, analyzing, and revising by a broadly representative expert workgroup who then gained input from HPM educators at a national meeting workshop. The CM draft was subsequently revised and then vetted through a national survey to 203 fellowship educators. Respondents were asked to "keep," "revise," or "exclude" each proposed CM with space for comments. An agreement of 75% among respondents was set as the criteria a priori for keeping a CM. Eighty-four of the 203 potential respondents participated in the survey. All items met the minimum agreement level of 75% or greater recommending keeping the CM. Greater than 85% of the respondents agreed to keep 19 of the 22 CMs with no revisions. Comments for revisions on other CMs were primarily related to changes in language and formatting, not conceptual underpinnings. CONCLUSION: A group consensus method strengthened by inclusion of a national survey to HPM fellowship educators resulted in a CM document that is both carefully developed and broadly vetted. Along with entrustable professional activities and new specialty-specific RMs, these CMs offer educators and trainees tools to create more comprehensive curricula and behaviorally based assessment tools for HPM fellowships and their stakeholders.

Confidence in palliative care issues by medical students and internal medicine residents.

BACKGROUND: Palliative care (PC) is a relatively new field in Brazil, but this knowledge is of great importance in medical practice. OBJECTIVE: To evaluate the degree of confidence among medical students and first-year and second-year internal medicine residents in addressing issues of death and terminal illness with patients and their families. METHOD: A modified version of the Self-Efficacy in Palliative Care Scale was applied to 293 students in their first year to sixth year at the School of Medicine of São José do Rio Preto and to 43 residents in their first year or second year of medical practice at the same institution in Brazil, in 2015. The questionnaire evaluated students' opinions on the need to include theoretical and practical classes on PC in the medical school. RESULTS: Students in their fifth year of medical school were more confident than the students in their first, second, third and fourth years; there were no statistically significant differences between fifth-year students, sixth-year students and the internal medicine residents. CONCLUSION: Residents were more confident than all of the medical school students except those in their fifth year (P<0.05) because they have more contact with terminally ill patients than other students do; fifth-year medical students are likely overestimating their abilities.

A collaborative approach to facilitate professionals to support the breathless patient.

OBJECTIVES: Breathlessness is a major problem for people in their last weeks of life. Breathlessness is considered to be multidimensional with physical, psychological, emotional, social and spiritual factors all playing a part. It has been recognised that specific training to health professionals is beneficial in order to improve the care for patients with breathlessness.Breathlessness courses have tended to focus on senior nurses. A new flexible and collaborative training course was designed to include a wider range of nurses and other health professionals in hospital, hospice, primary care and community settings. The aim of the 'Practical Skills to Support the Breathless Patient' programme was to make patients and carers feel better supported in their breathlessness, for health professionals to develop confidence and skills in using proven interventions, and to adopt a flexible educational design that could be adapted to different contexts. METHODS: The course is learner-centred and teaching methods encourage interaction and participation via a mix of lectures and discussions with practical skills-focused, experiential workshops in smaller groups. Case study work was included to integrate learning with participants' practice environment. Evaluation is built in during the course, so adaptations can be made throughout to respond to changing learner needs. RESULTS: Participants reported increased confidence in terms of knowledge and applying this within everyday practice. The theory-practice dynamic worked well within each participant' specific work context in particular through the case study approach. CONCLUSIONS: The course developed a number of innovative approaches, such as multi-disciplinary learning groups, regular feedback loops, reflexive learning about putting theory into practice and long-term follow-up. Combining these elements increases professionals' confidence and sustains new clinical practice.

Systematic review and meta-analysis on non-opioid analgesics in palliative medicine.

Non-opioid analgesics are widely used for pain relief in palliative medicine. However, there is a lack of evidence-based recommendations addressing the efficacy, tolerability, and safety of non-opioids in this field. A comprehensive systematic review and meta-analysis on current evidence can provide a basis for sound recommendations in clinical practice. A database search for controlled trials on the use of non-opioids in adult palliative patients was performed in Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, PsycINFO, and EMBASE from inception to 18 February 2018. Endpoints were pain intensity, opioid-sparing effects, safety, and quality of life. Studies with similar patients, interventions, and outcomes were included in the meta-analyses. Our systematic search was able to only identify studies dealing with cancer pain. Of 5991 retrieved studies, 43 could be included (n = 2925 patients). There was no convincing evidence for satisfactory pain relief by acetaminophen alone or in combination with strong opioids. We found substantial evidence of moderate quality for a satisfactory pain relief in cancer by non-steroidal anti-inflammatory drugs (NSAIDs), flupirtine, and dipyrone compared with placebo or other analgesics. There was no evidence for a superiority of one specific non-opioid. There was moderate quality of evidence for a similar pain reduction by NSAIDs in the usual dosage range compared with up to 15 mg of morphine or opioids of equianalgesic potency. The combination of NSAID and step III opioids showed a beneficial effect, without a decreased tolerability. There is scarce evidence concerning the combination of NSAIDs with weak opioids. There are no randomized-controlled studies on the use of non-opioids in a wide range of end-stage diseases except for cancer. Non-steroidal anti-inflammatory drugs, flupirtine, and dipyrone can be recommended for the treatment of cancer pain either alone or in combination with strong opioids. The use of acetaminophen in the palliative setting cannot be recommended. Studies are not available for long-term use. There is a lack of evidence regarding pain treatment by non-opioids in specific cancer entities.

Attitudes to specialist palliative care and advance care planning in people with COPD: a multi-national survey of palliative and respiratory medicine specialists.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) guidelines recommend early access to palliative care together with optimal, disease-directed therapy for people with advanced disease, however, this occurs infrequently. This study explored the approaches of respiratory and palliative medicine specialists to palliative care and advance care planning (ACP) in advanced COPD. METHODS: An online survey was emailed to all specialists and trainees in respiratory medicine in Australia and New Zealand (ANZ), and to all palliative medicine specialists and trainees in ANZ and the United Kingdom. RESULTS: Five hundred seventy-seven (33.1%) responses were received, with 440 (25.2%) complete questionnaires included from 177 respiratory and 263 palliative medicine doctors. Most respiratory doctors (140, 80.9%) were very or quite comfortable providing a palliative approach themselves to people with COPD. 113 (63.8%) respiratory doctors recommended referring people with advanced COPD to specialist palliative care, mainly for access to: psychosocial and spiritual care (105, 59.3%), carer support (104, 58.5%), and end-of-life care (94, 53.1%). 432 (98.2%) participants recommended initiating ACP discussions. Palliative medicine doctors were more likely to recommend discussing: what palliative care is (p < 0.0001), what death and dying might be like (p < 0.0001) and prognosis (p = 0.004). Themes highlighted in open responses included: inadequate, fragmented models of care, with limited collaboration or support from palliative care services. CONCLUSIONS: While both specialties recognised the significant palliative care and ACP needs of people with advanced COPD, in reality few patients access these elements of care. Formal collaboration and bi-directional support between respiratory and palliative medicine, are required to address these unmet needs.

Breakthrough cancer pain (BTcP) management: a review of international and national guidelines.

OBJECTIVE: Breakthrough cancer pain (BTcP) is common and has a significant impact on the quality of life of patients with cancer. This review compares current national/international BTcP guidelines in order to identify disparities and priorities for further research. METHODS: Relevant guidelines were identified using searches of PubMed, the National Guideline Clearinghouse, the internet (commercial search engines), and correspondence with key opinion leaders and relevant pharmaceutical companies. Identified guidelines were compared, using the Association for Palliative Medicine of Great Britain and Ireland recommendations as the 'reference' guideline. RESULTS: Ten specific BTcP guidelines were identified/reviewed, as well as major international generic cancer pain guidelines. In general, there was good agreement between the specific BTcP guidelines, although there remain some differences in terms of definition, diagnostic criteria and treatment of BTcP. Disparities between the different BTcP guidelines invariably reflect personal opinion rather than research evidence. Generic cancer pain guidelines continue to support the use of oral opioids as rescue medication, while specific BTcP guidelines invariably endorse the use of transmucosal opioids as rescue medication. CONCLUSION: Current guidelines agree on many aspects of the management of BTcP. However, the evidence to support current guidelines remains low grade, and so more research is needed in this area of care. Moreover, there needs to be an international consensus on the definition and diagnosis criteria of BTcP.

Use of Artificial Hydration at the End of Life: A Survey of Australian and New Zealand Palliative Medicine Doctors.

BACKGROUND: Dying is ubiquitous, yet the optimal management of hydration in the terminal phase is undetermined. Palliative care (PC) doctors' practices may act as a de facto measure of the benefits and burdens of artificial hydration (AH) use. OBJECTIVE: To identify PC doctors' AH prescribing practices for imminently dying patients and possible influencing factors. METHODS: An online survey of doctors belonging to the Australian and New Zealand Society of Palliative Medicine. RESULTS: One hundred and thirty-six surveys were completed (30% response rate). AH use for patients in the prognosticated last week of life was low: 77% of respondents prescribed AH to 0-10% of patients and 3% of respondents prescribed to more than 20%. The most common reason for prescribing AH was palliation of family/patient concern rather than a physical symptom. The majority thought there was no effect of AH on survival, or on symptoms of fatigue (90%), reduced level of consciousness (88%), agitation (75%), nausea (69%), vomiting (68%), myoclonus (66%), thirst (65%), delirium (62%), cough (57%), or bowel obstruction (50%). AH was thought to worsen subcutaneous edema (94%), upper respiratory tract secretions (85%), ascites (73%), physical discomfort (72%), dyspnea (62%), and urinary symptoms (57%). CONCLUSION: PC doctors from Australia and New Zealand reported lower use of AH for dying patients compared to international counterparts. The study showed high concordance in respondents' opinions: most thought AH was unlikely to provide clinical benefit and might cause harm. Further studies are needed to determine best practice of AH use at the end of life.

Impact and Reception of a Required 4-Week Palliative Medicine Rotation.

BACKGROUND AND OBJECTIVES: Hospice and palliative medicine (HPM) is one of three Accreditation Council for Graduate Medical Education accredited clinical subspecialties available to family medicine graduates for fellowship training. Despite this, training is not currently a curriculum requirement. We have pioneered a required 4-week palliative medicine rotation into the curriculum. METHODS: Twenty-eight residents who completed the palliative medicine rotation across four classes were surveyed to assess how the rotation improved their level of comfort with providing end-of-life (EOL) care and to demonstrate the need of formal palliative medicine training. Wilcoxon signed ranks test was used to detect statistical differences between the mean level of comfort of residents pre- and postrotation with providing the basic skills needed to practice HPM. RESULTS: The HPM rotation significantly improved the residents' level of comfort in all areas of measured EOL care (P<0.001). All residents surveyed strongly agreed that the rotation was valuable to their future and 100% of residents strongly agreed that an HPM rotation should be required. CONCLUSIONS: Formal HPM training should be a required component in residency education and considerations should be given to the 4-week format. This rotation provides a model that can be implemented in other residency programs nationally. Implementation of this rotation may help close the enormous gap of patients not receiving quality EOL care.

Self-Assessment of Skills and Competencies among Residents Participating in a Pediatric Hospice and Palliative Medicine Elective Rotation.

OBJECTIVE: To describe our institutional experience with a four-week pediatric HPM elective rotation and its impact on residents' self-rated competencies. BACKGROUND: In the spirit of bolstering primary hospice and palliative medicine (HPM) skills of all pediatricians, it is unclear how best to teach pediatric HPM. An elective rotation during residency may serve this need. METHODS: An anonymous online survey was distributed to pediatric and internal medicine/pediatrics residents at a single, tertiary academic children's hospital. Respondents were asked to rate education, experience, and comfort with five aspects of communication with families of children with terminal illnesses and six domains of managing the symptoms of terminal illnesses. Self-ratings were recorded on a 1-5 scale: none, minimal, moderate, good, or excellent. Demographic data, including details of training and prior HPM training, were collected. Respondents completed a set of six questions gauging their attitude toward palliative care in general and at the study institution specifically. RESULTS: All respondents desire more HPM training. Those residents who self-selected to complete a pediatric HPM elective rotation had significantly higher self-ratings in 10 of 11 competency/skill domains. Free-text comments expressed concern about reliance on the specialty HPM team. DISCUSSION: A pediatric HPM elective can significantly increase residents' self-rated competency. Such rotations are an under-realized opportunity in developing the primary HPM skills of pediatricians, but wider adoption is restricted by the limited availability of pediatric HPM rotations and limited elective time during training.

Medical students' attitudes towards participating in a palliative medicine course: A new specialty in Israel.

BACKGROUND: Palliative medicine is a growing field in Israel, and its training program is still in process. The current study aimed to evaluate students' attitudes regarding a course in palliative care established in a division of oncology. METHOD: Some 45 medical students in their 5th to 6th years participated in a one-week course on palliative care. At the end of each training week, students were asked to complete a questionnaire, evaluating their attitudes regarding different aspects of the program content, such as its importance and relevance to their training as physicians, as well as the contribution of specific parts of the program to their knowledge regarding palliative care. RESULTS: The overall satisfaction of the 45 students was high. The most contributory parts of the course were the multidisciplinary team and the complementary and alternative medicine. Participating in the staff meetings and accompanying physicians in their daily work were scored as the least contributory parts.Significance of resultsThis preliminary study demonstrated students' overall high satisfaction with the newly established palliative care course and their need for more practical skills. Future studies should investigate and evaluate educational programs in palliative care in order to establish suitable training for medical students.

[Choosing wisely at the end of life : Recommendations of the German Society for Palliative Medicine (DGP)]. / Klug entscheiden am Lebensende : Empfehlungen der Deutschen Gesellschaft für Palliativmedizin (DGP).

In addition to an overuse of unnecessary or no longer indicated diagnostic or therapeutic procedures at the end of life in the sense of overtreatment, there is often also a lack of therapeutic awareness in terms of a healthcare deficit, for example concerning the recognition and treatment of symptoms and complex burden of the disease. Sticking closely to the methodology of the German S3 "Palliative Medicine" guideline, the Choosing wisely recommendations of the German Society for Palliative Medicine address various examples of over- and underuse of healthcare services and treatment at the end of life, and thus also mirror basic principles of palliative medical care.

Perceptions of family members of palliative medicine and hospice patients who experienced music therapy.

PURPOSE: Evidence shows that music therapy aids in symptom management and improves quality of life for palliative medicine and hospice patients. The majority of previous studies have addressed patient needs, while only a few addressed the needs of family members. The primary purpose of this study was to understand family members' perceptions of music therapy experienced by a relative in palliative medicine or hospice. Patient self-reported scales and music therapist assessment of change were also investigated. METHODS: Patients scored their symptoms (pain, anxiety, depression, shortness of breath, and mood) before and after music therapy sessions. One family member present during the session assessed perceived effect on the patient's pain, anxiety, depression, shortness of breath, stress level, restlessness, comfort level, mood, and quality of life. The effect on family member's stress level, quality of life, and mood and helpfulness of the music therapy session for the patient and self were studied. Recommendations about future patient participation in music therapy and qualitative comments were also solicited. RESULTS: Fifty family member/patient dyads participated in the study. Family member perceptions were positive, with 82% of responders indicating improvement for self and patient in stress, mood, and quality of life; 80% rating the session as extremely helpful; and 100% of 49 recommending further music therapy sessions for the patient. Patients reported statistically significant improvement in pain, depression, distress, and mood scores. CONCLUSIONS: Family members of patients in palliative medicine and hospice settings reported an immediate positive impact of music therapy on the patient and on themselves. More research needs to be conducted to better understand the benefits of music therapy for family members.
