Introduction:
There is an increase on cancer prevalence and, consequently, a higher number of people that require palliative care, making an influence on the family and the main carer.
Objectives:
Method:
Randomised, double-blind, multi-centre clinical trial in the field of primary health care, conducted in 5 clinical management units belonging to Málaga-Guadalhorce health district and performed in oncological palliative care patients and carers. Two samples of 40 palliative care patients and two samples of 41 carers. The intervention group will undergo a 7-days intervention with music sessions, the control group will be given seven sessions of retraining in therapeutical education. Objectives will be evaluated through the following tools: Edmonton Scale, Symptom Assessment System, EORTC QLQ-C30, Caregiver Burden Scale, Pittsburgh Sleep Quality Index, Accelerometer, Epworth Sleepiness Scale (ESS), The Quality of Life Family Version, Client Satisfaction Questionnaire and Economical valuation.
To assess the objectives evaluations will be performed through home visit, both pre-intervention and a week after the beginning of the intervention for both groups. A follow-up visit will be made a month after the intervention to regard some economical parameters.
Statistical analysis:
The basal values of both groups will be compared. These values will be compared before and after the intervention, in the control and intervention group through Student t-test for normal continuous variables, and through Wilcoxon t-test for paired data in not normal continuous variables. In addition to the bivariated analysis, a multiple lineal regression will be carried out. The economical valuation will be a cost-effectiveness analysis. For each group we will measure cost, incremental cost, AVAC effectiveness, incremental effectiveness, dominance and, in case there is none, the results will be expressed in terms of incremental cost-effectiveness. To assess the costs, direct sanitary costs and intervention related costs will be considered.
SPSS 23 will be the statistical software to use, along with Epidat 3.01. 95% confidence range will make p values under 0,05 (p<0.05) statistically significant.
Full description
Background and status.
Cancer presents an enormous challenge to the world public health. Every year, 8 million people die because of the disease, meaning it´s one of the main causes of death in the world and the pathology changes the patient in all their levels: physical (appearance, treatment consequences), emotional (reactions variability, feelings, distress), cognitive (personality and character, ways of facing the problem and adaptability), social and spiritual. It produces suffering on an individual, familiar and social level.
An estimation of 50-60% of the people that perish in Spain, based on age and death causes, does so after the disease reaches an advanced stage, being terminal. Terminal patients require great amounts of nursing and health care, being these needs very heterogenic and implying both sanitary and social resources.
According to the Andalusian Plan for Palliative Care estimations, Andalusian population susceptible to receive palliative care stands between a minimum of 31.553 and a maximum of 62.887 inhabitants.
World Health Organization (WHO) defined palliative care as: 'An approach that improves the quality of life of patients and their families facing the problem associated with life-threatening illness, through the prevention and relief of suffering by means of early identification and impeccable assessment and treatment of pain and other problems, physical, psychosocial and spiritual'.
A revision carried out in 2011 by the World Federation of Music Therapy (WFMT) defined music therapy as 'The professional use of music and its elements as an intervention in medical, educational, and everyday environments with individuals, groups, families, or communities who seek to optimize their quality of life and improve their physical, social, communicative, emotional, intellectual, and spiritual health and wellbeing'.
Integrating music therapy into palliative care intervention could help patients and caregivers to deal with some of the physical, emotional, social and spiritual needs they face: making changes in pain and anxiety perception easier, improving the mood, relaxing, enabling better emotional expressions, connecting with spirituality and offering support during mourning.
To perform adequate care services at home, a main caregiver is needed to guarantee that patients have all their basic needs cover, follow the scheduled treatment for the symptoms, get continuous family and social support and attention, specially at the end. But the caregiver's health can be affected, specially if subjected to an overload of work or adaptation to rapid changes in the person taken care of, affecting its quality of life.
For the most optimal performance of the caregiver, it is needed that they are also recognised. A systematic review in 2008 showed a lack of evidence-based interventions that support attention given to the caregivers of cancer patients, encouraging nurses to keep researching and putting to test intervention that reduce the burden on caregivers. However, several interventions in the attention to caregivers of terminal or palliative care patients proves their efficacy. Regarding the use of music therapy to achieve an improvement on the caregiver wellbeing, very few studies can be found.
Bibliography offers more and more studies and systematic reviews regarding music therapy in the intervention of cancer patients under palliative care, where the main goal is the study of the music therapy as a complementary treatment and a no-pharmacological treatment of anxiety, depression, pain, quality of life and physiological symptoms, pointing to its efficacy.
Kordovan et al. (2016) performed a prospective review of viability, acceptance and possible beneficial effects of music therapy in hospitalised terminal cancer patients, and the authors summarised that music therapy, especially receptive methods, are feasible and well regarded among these patients. A controlled randomised trial performed with hospitalised palliative care patients revealed music therapy to be an effective treatment to promote relaxation and wellbeing for the patients. The music therapy didn't differ from the control treatment in terms of pain reduction, but it was significantly different in the fatigue aspect of quality of life scale , being considerably lower. Control treatment was verbal relaxation.
On economic aspects, Keenan A., Keithley JK. (2015) made an integrating review about music effect in adults' cancer pain, stating a limited evidence of music therapy in pain treatment. Integrative methods using music may represent an important intervention that nurses can suggest as an economical, non-toxic and easily available to potentially reduce cancer pain. Efficiency wise, several publications point to a reduction in expenses mainly due to a lower medication intake, and it may as well mean a reduced number of professional attention and hours dedicated to deal with the symptoms.
Another systematic review by Qi He Mable L., Drury VB., Hong PW. (2010) showed the development of two important finding: music therapy can and must be used in palliative environments to promote social interaction and communication with family, friends, other patients and health practitioners; and it may as well be used to provide support to patients' needs. Through music therapy, patients noticed an improvement on social interaction and communication with their surroundings and a better way to satisfy their physical, psychological and spiritual needs.
In a Cochrane review from Bradt et al. (2016), authors concluded that music intervention can bring positive results on anxiety, pain, mood and quality of life in cancer patients, but the results must be read with caution as the bias risk is high.
In a study carried out by Gallager et al. (2017), it was proposed to understand the insight of family members regarding music therapy undertaken by the palliative care patients. Out of 50 participants, 82% indicated an improvement for both the relative and the patient in stress management, mood and quality of life, the session being rated as extremely useful in the 80% of cases, and 100% of them recommended more sessions. Patients reported a statistically significant improve regarding pain, depression, distress and mood. The study concludes that palliative patients´ relatives inform of an improvement on both patients and relatives, but more research is needed to fully comprehend the beneficial effects on the family.
This study proposes using music therapy on both patients and caregivers, differing in the way of choosing the music. Whereas most studies in the bibliography resort to picking relaxing music among different categories, such as jazz, folk or country, we aim to ask the participants to choose the music the want to listen to. This study will consider that the same genre can vary in the options available for the patients, triggering different emotions in different people depending on personal experiences. Although people can distinguish between sad and cheerful tunes, most people have preferred music that cheer us up or saddens us and we use it to our convenience, so the study will focus on the music that makes each patient feel better, assuming than that is the key to achieve better results.
This clinical trial will consider all recommendations from the authors of the Cochrane 2016 review to avoid bias.
Despite the high potential benefit that it could be to optimise medication intake and reduce sanitary resources expenditure, the evidence on cost-effectiveness in music intervention is very limited, so this study will also try to determine the efficiency of the intervention. Economic evaluation methods will be applied, along with a helping tool to determine, through decisions taken, the optimal use of sanitary resources and allowing the gathering of feedback of the impact of the intervention for both the organisation and the social program.

Specific objectives:
Methodology:
Randomised, double-blind, multi-centre clinical trial in the field of primary health care, conducted in 5 clinical management units belonging to Málaga-Guadalhorce health district and performed in oncological palliative care patients included into the Assistance Procedure of Palliative Care in digital health history (DIRAYA) and their unofficial caregivers.
The palliative care patient and the caregiver are offered to participate and, if both accept, they will be offered an envelope that will be valid for both, taking part into the study in the same group. If only one of the two accepts, they will be offered an envelope as well. Participants will be taken until the desired number of cases is reached.
Once the researcher in charge of randomisation knows which groups the patient and the caregiver belong to according to the envelope, they will be informed of the procedure they will undergo without knowing their belonging to either the control or the intervention group.
• Sample size: the most relevant variable to be considered is anxiety for palliative care patients. In Bradt et al. (2016) revision it was presented with a standard deviation of 1'8 in a similar sample using a scale with a wider range than the one used in this study. Previous bibliography shows significant differences after music intervention, with a specific estimation of difference in 7 (29% of standard deviation). A research using the Edmonton Scale (in oncological patients, treatments with ginseng) showed a value of 0-83 points with a standard deviation of 2.34 (35% of standard deviation). If we consider as clinically relevant a decrease of 2 points in the anxiety before-after, expecting a standard deviation of at most 2.5 in our population; with an alpha error of 0.05 and a beta of 0.10 2 samples of 33 subjects are needed, choosing the ration for the samples in 1:1. A 20% increase, making it 2 samples of 40 subjects, would be desirable to avoid patients loss/dropping the intervention.
According to Hanser et al. (2011), there is an increase in the caregivers´ satisfaction with the music therapy, with a standard deviation of 1.33 on relaxation, 1.87 on comfort, and 1.23 in happiness. If we take a 1-point increase in caregivers' happiness as relevant, 2 samples of 34 carers would be needed. A 20% increase, making it 2 samples of 41 subjects would be desirable to avoid subjects loss/dropping the intervention.
Procedures by group
To evaluate the expected objectives, valuations by means of home visits will be made, both preintervention and a week after the start of the intervention, for both groups. A home visit will also be done after a month to assess economic parameters.
The following valuation scales will be used: Edmonton Scale, Symptoms Assessment System, EORTC QLQ-C30, Caregiver Burden Scale, Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale (ESS), The Quality of Life Family Version, Client Satisfaction Questionnaire, and Economic valuation.
Statistical analysis: a descriptive study of the collected factors will be carried out by means of media and standard deviation for normal continuous variables; calculating confidence interval for punctual estimations; through median and interquartile range in not normal continuous variables; and frequencies and percentages in categoric variables. Adjustment to normality will be determined by the Shapiro-Wilk test. The basal values of both groups will be compared before and after the intervention, in the control and intervention group through Student t-test for normal continuous variables, and through Wilcoxon t-test for paired data in not normal continuous variables. In addition to the bivariated analysis, a multiple lineal regression will be carried out, where the dependant variables will be: pain, anxiety, depression, mood, insomnia and quality of life; the independent variables will include intervention, sociodemographic (sex, age, studies, civil status) and clinical (pathology, palliative care time) variables of the subjects. The economic valuation will be a cost-effectiveness analysis, following the recommendations proposed in the guide to evaluate economic performances in health technologies. For each group, we will measure the cost, incremental cost, AVAC effectiveness, incremental effectiveness, dominance and, in case there is no dominance, results will be showed as an incremental cost-effectiveness ratio. To assess the costs, direct sanitary costs and intervention related costs will be considered. Sanitary resources costs will be estimated using the public prices set by the SSPA58. The cost of direct resources used during the intervention will be estimated by means of their recommended retail price (RRP). To calculate the AVAC, the EuroQol-5D-5L Questionnaire will be used. Uncertainty variables analysis will be subject to univariant and polyvariant sensitivity analysis.
In the event of finding statistically significant data in normal variables, the confidence range will be calculated on 95%, allowing the estimation of values where the difference is found. SPSS will be the statistical software to use, along with Epidat 3.01. 95% confidence range will make p values under 0,05 (p<0.05) statistically significant.
