The Suffering Pictogram: Measuring Suffering in Palliative Care

A Multicentric Field Test to Study the Validity and Feasibility of the SHS-tool to Screen for Serious Health-related Suffering in Adult Patients with Cancer

Objectives

The 2017 Lancet Commission reports 'Serious Health-related Suffering' (SHS) as an abyss in healthcare services. It lists 20 common health conditions and 15 symptoms as commonly associated with SHS. In 2015, 80% of SHS prevalence, an estimated 61 million, was noted as from low-middle-income countries. Acknowledging the high prevalence of SHS in cancer patients and aligning with global efforts to address and alleviate the suffering, the National Cancer Grid of India developed and evaluated the SHS screening tool (SHS-tool). The SHS tool was developed during phase 1 of the study through a systematic consensus-building methodology. During phase 2, the validity and feasibility study of the SHS tool was completed through a multicentric field test, which is described here.

Materials and Methods

The SHS tool developed during phase 1 was field-tested across nine tertiary cancer care centres (TCC sites) selected from different healthcare sectors and regions of India. The study utilised a purposive sample of 254 cancer patients to evaluate the validity of the SHS screening tool at selected sites and additionally recorded the feasibility, relevance, acceptability and feedback comments from patients (n = 121), research associates (n = 11) and principal investigators (PIs) (n = 9). A documented interview of the patient within the same timeframe by experienced personnel selected by the PI served as the standard.

Results

The field-test TCC-sites represented government academic institutions, non-government and private sectors. The sites used patient waiting areas and inpatient/daycare wards for conducting field tests. The Cronbach's alpha of the SHS-tool questionnaire showed an internal consistency of 0.728. The tool detected SHS in 137/254 patients, compared to 116/254 through the interview method. The outcomes concurred with that of the interview in 64.17% of instances. The tool exhibited a sensitivity of 70% and specificity of 59%. 66.67% of patients might not have reached the interviewers if not for the field test processes. The feasibility questionnaire responses from patients (n = 121) indicated ease of understanding (91.74%), ease of use (92.56%) and relevance (89.26%). The selected settings were found suitable by 96.69%. Feedback responses from research associates indicated ease of administration (10/11) and relevance (8/11) and found no reasons preventing its use (8/11). The feedback comments from the stakeholders were thematically grouped for insights.

Conclusion

The SHS tool is validated for screening SHS where none exists. It has been found to be a feasible, relevant and acceptable tool for use in adult cancer patients attending TCCs across India. Insights from analysing the feedback comments from the stakeholders have been integrated as 'instruction for use' for refined implementation of the SHS tool. The SHS tool may be utilised to recognise and trigger an in-depth evaluation and expedited access to essential palliative care packages towards alleviating it, as recommended by the Lancet Commission. Future studies using the SHS tool in other disease conditions with a high burden of SHS can assess its wider applicability.

Mindfulness-based supportive therapy on reducing suffering in patients with advanced cancer: randomised controlled trial

OBJECTIVES

Suffering is common among patients with advanced cancer. The practice of mindfulness during patient care can potentially reduce suffering. We aimed to examine the efficacy of mindfulness-based supportive therapy (MBST) on reducing suffering in patients with advanced cancer.

METHODS

We conducted a parallel-group, single-blinded, randomised controlled trial at the University of Malaya Medical Centre, Malaysia. Seventy-three patients with advanced cancer with an overall suffering score ≥4/10 based on the Suffering Pictogram were recruited and randomly assigned into either the MBST group (n=34) or the control group (n=39).

RESULTS

There was a statistically significant reduction in the overall suffering score in the MBST group compared with the control group (U=432.5, median1=-2.0, median2=-1.0, z=-2.645, p=0.008). There was also significant improvement in the total Hospital Anxiety and Depression Scale score (U=483.5, median1=-4.0, median2=-3.0, z=-1.994, p=0.046), and the total Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being score (U=252.0, median1=+14.5, median2=+5.0, z=-4.549, p=0.000) in the MBST group compared with the control group.

CONCLUSIONS

The results provided evidence that the practice of MBST during patient care could promote positive psychosocial outcomes.

Mindful gratitude journaling: psychological distress, quality of life and suffering in advanced cancer: a randomised controlled trial

CONTEXT

Numerous studies have shown that gratitude can reduce stress and improve quality of life.

OBJECTIVE

Our study aimed to examine the effect of mindful gratitude journaling on suffering, psychological distress and quality of life of patients with advanced cancer.

METHODS

We conducted a parallel-group, blinded, randomised controlled trial at the University of Malaya Medical Centre, Malaysia. Ninety-two adult patients with advanced cancer, and an overall suffering score ≥4/10 based on the Suffering Pictogram were recruited and randomly assigned to either a mindful gratitude journaling group (N=49) or a routine journaling group (N=43).

RESULTS

After 1 week, there were significant reductions in the overall suffering score from the baseline in both the intervention group (mean difference in overall suffering score=-2.0, 95% CI=-2.7 to -1.4, t=-6.125, p=0.000) and the control group (mean difference in overall suffering score=-1.6, 95% CI=-2.3 to -0.8, t=-4.106, p=0.037). There were also significant improvements in the total Hospital Anxiety and Depression Scale score (mean difference=-3.4, 95% CI=-5.3 to -1.5, t=-3.525, p=0.000) and the total Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being score (mean difference=7.3, 95% CI=1.5 to 13.1, t=2.460, p=0.014) in the intervention group after 7 days, but not in the control group.

CONCLUSION

The results provide evidence that 7 days of mindful gratitude journaling could positively affect the state of suffering, psychological distress and quality of life of patients with advanced cancer.

TRIAL REGISTRATION NUMBER

The trial was registered with the Australian and New Zealand Clinical Trials Registry (ACTRN1261800172191) and conducted in accordance with the Declaration of Helsinki.

Existential spectrum of suffering: concepts and moral valuations for assessing intensity and tolerability

This paper has two aims. The first is to defend a recent critique of the leading medical theory of suffering, which alleges too narrow a focus on violent experiences of suffering. Although sympathetic to this critique, I claim that it lacks a counterexample of the kinds of experiences the leading theory is said to neglect. Drawing on recent clinical cases and the longer intellectual history of suffering, my paper provides this missing counterexample. I then answer some possible objections to my defence, before turning to my second aim: an expansion of my counterexample into a spectrum of suffering that varies according to the selves and purposes that suffering affects. Next, I connect this spectrum to the tolerability of suffering, which I distinguish from its affective intensity. I conclude by outlining some applications of this distinction for the psychometric reliability of assessment instruments that measure suffering in clinical contexts.

Standardized system and App for continuous patient symptom logging in gastroduodenal disorders: Design, implementation, and validation

BACKGROUND

Functional gastroduodenal disorders include functional dyspepsia, chronic nausea and vomiting syndromes, and gastroparesis. These disorders are common, but their overlapping symptomatology poses challenges to diagnosis, research, and therapy. This study aimed to introduce and validate a standardized patient symptom-logging system and App to aid in the accurate reporting of gastroduodenal symptoms for clinical and research applications.

METHODS

The system was implemented in an iOS App including pictographic symptom illustrations, and two validation studies were conducted. To assess convergent and concurrent validity, a diverse cohort with chronic gastroduodenal symptoms undertook App-based symptom logging for 4 h after a test meal. Individual and total post-prandial symptom scores were averaged and correlated against two previously validated instruments: PAGI-SYM (for convergent validity) and PAGI-QOL (for concurrent validity). To assess face and content validity, semi-structured qualitative interviews were conducted with patients.

KEY RESULTS

App-based symptom reporting demonstrated robust convergent validity with PAGI-SYM measures of nausea (r_S  =0.68), early satiation (r_S  =0.55), bloating (r_S  =0.48), heartburn (r_S  =0.47), upper gut pain (r_S  =0.40), and excessive fullness (r_S  =0.40); all p < 0.001 (n = 79). The total App-reported Gastric Symptom Burden Score correlated positively with PAGI-SYM (r_S  =0.56; convergent validity; p < 0.001), and negatively with PAGI-QOL (r_S  = -0.34; concurrent validity; p = 0.002). Interviews demonstrated that the pictograms had adequate face and content validity.

CONCLUSIONS AND INFERENCES

The continuous patient symptom-logging App demonstrated robust convergent, concurrent, face, and content validity when used within a 4-h post-prandial test protocol. The App will enable standardized symptom reporting and is anticipated to provide utility in both research and clinical practice.

Contributing and Relieving Factors of Suffering in Palliative Care Cancer Patients: A Descriptive Study

To palliate suffering, understanding the circumstances leading to suffering and its amelioration could be helpful. Our study aimed to explore contributing and relieving factors of suffering in palliative care. Adult palliative care stage III or IV cancer in-patients were recruited from University of Malaya Medical Centre. Participants recorded their overall suffering score from 0 to 10 three times daily, followed by descriptions of their contributing and relieving factors. Factors of suffering were thematically analysed with NVIVO. Descriptive data were analysed with SPSS. 108 patients participated. The most common contributing factor of suffering was health factor (96.3%), followed by healthcare factor (78.7%), psychological factor (63.0%) and community factor (20.4%). The most common relieving factor was health factor (88.9%), followed by psychological factor (78.7%), community factor (75.9%) and healthcare factor (70.4%). Self-reported assessment of suffering offers a rapid approach to detect bothering issues that require immediate attention and further in-depth exploration.

The German version of the Mini Suffering State Examination (MSSE) for people with advanced dementia living in nursing homes

Background

The Mini Suffering State Examination (MSSE) has been explicitly recommended to assess suffering in dementia patients. This study aimed to develop a German version of the MSSE and assess its psychometric properties involving people with advanced dementia (PAD) in a nursing home setting.

Methods

The MSSE was translated into German, and 95 primary nurses administered it cross-sectionally to 124 PAD in Zurich, Switzerland. The psychometric properties of the German MSSE version were calculated for this population.

Results

The mean age of the PAD was 83.3 years (SD = 9.1, range = 55–102 years), and 98 of them (79.0%) were women. The Kuder-Richardson Formula 20 coefficient for the entire scale (0.58), the eight items relating to objective health conditions (0.39), and the professional and family estimation of the patient’s suffering (0.64) indicated low internal consistency. A confirmatory factor analysis indicated an unsatisfactory fit to a one-factor structure, with a comparative fit index and root mean square error of approximation of 0.71 and 0.08, respectively, and a Tucker–Lewis index of 0.64. The MSSE total score was significantly but moderately correlated with the total scores of the Symptom Management–End-of-Life with Dementia (SM-EOLD) scale (Pearson’s correlation coefficient (r) = -0.44; p < 0.05), the physical suffering scores (r = 0.41; p < 0.05), and the psychological suffering scores (r = 0.55; p < 0.05).

Conclusions

The German version of the MSSE questionnaire did not perform well in the nursing home setting involving PAD. The instrument had low internal consistency, doubtful validity, and could not discriminate between suffering and other distressing symptoms. We do not recommend its use in this population.

Increasing our understanding of nonphysical suffering within palliative care: A scoping review

OBJECTIVE

Nonphysical suffering is emotional, psychological, existential, spiritual, and/or social in nature. While palliative care is a discipline dedicated to the prevention and relief of suffering - both physical and nonphysical - little is known about existing research specific to nonphysical suffering within the context of palliative care. This scoping review helps to fill this gap.

METHOD

Three hundred and twenty-eight unique records were identified through a systematic search of three databases (MEDLINE, CINAHL, and PsycINFO). The following keywords were used: (suffering) AND (palliative OR "end of life" OR "end-of-life" OR hospice OR dying OR terminal* ill*). Thirty studies published between 1998 and 2019 met the inclusion criteria.

RESULTS

Losses, worries, and fears comprise patients' primary sources of nonphysical suffering. Patients face numerous barriers in expressing their nonphysical suffering to healthcare providers. The idea that patients can choose how they perceive their circumstances, thereby minimizing their nonphysical suffering, is pervasive in the research. The nature of nonphysical suffering experienced by family caregivers and palliative care clinicians is revealed in the review. The unique and sensitive interplay between nonphysical suffering and both palliative sedation and requests for hastened death is also evident. Overall, seven themes can be identified: (i) patients' experiences of nonphysical suffering; (ii) patient coping mechanisms; (iii) efforts to measure nonphysical suffering; (iv) palliative sedation; (v) requests for hastened death; (vi) family suffering; and (vii) clinician suffering.

SIGNIFICANCE OF RESULTS

This is the first scoping review to map palliative care's research specific to suffering that is social, emotional, spiritual, psychological, and/or existential in nature. Its findings expand our understanding of the nature of nonphysical suffering experienced by patients, families, and palliative care clinicians. The review's findings have significant implications for front-line practice and future research.

eSyM: An Electronic Health Record-Integrated Patient-Reported Outcomes-Based Cancer Symptom Management Program Used by Six Diverse Health Systems

PURPOSE

Collecting patient-reported outcomes (PROs) can improve symptom control and quality of life, enhance doctor-patient communication, and reduce acute care needs for patients with cancer. Digital solutions facilitate PRO collection, but without robust electronic health record (EHR) integration, effective deployment can be hampered by low patient and clinician engagement and high development and deployment costs. The important components of digital PRO platforms have been defined, but procedures for implementing integrated solutions are not readily available.

METHODS

As part of the NCI's IMPACT consortium, six health care systems partnered with Epic to develop an EHR-integrated, PRO-based electronic symptom management program (eSyM) to optimize postoperative recovery and well-being during chemotherapy. The agile development process incorporated user-centered design principles that required engagement from patients, clinicians, and health care systems. Whenever possible, the system used validated content from the public domain and took advantage of existing EHR capabilities to automate processes.

RESULTS

eSyM includes symptom surveys on the basis of the PRO-Common Terminology Criteria for Adverse Events (PRO-CTCAE) plus two global wellness questions; reminders and symptom self-management tip sheets for patients; alerts and symptom reports for clinicians; and population management dashboards. EHR dependencies include a secure Health Insurance Portability and Accountability Act-compliant patient portal; diagnosis, procedure and chemotherapy treatment plan data; registries that identify and track target populations; and the ability to create reminders, alerts, reports, dashboards, and charting shortcuts.

CONCLUSION

eSyM incorporates validated content and leverages existing EHR capabilities. Build challenges include the innate technical limitations of the EHR, the constrained availability of site technical resources, and sites' heterogenous EHR configurations and policies. Integration of PRO-based symptom management programs into the EHR could help overcome adoption barriers, consolidate clinical workflows, and foster scalability and sustainability. We intend to make eSyM available to all Epic users.

Addressing Suffering in Patients With Psychiatric Disorders

BACKGROUND

Patients with psychiatric disorders (as well as general medical conditions) often describe their lives in terms of suffering. Although suffering is honored as a central focus of physicians' concerns, it is not even indexed in the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition. Generally connoting severe, prolonged distress, suffering can be distinguished from pain, depression, and anxiety. The aims of this article are to consider whether attending to suffering per se in psychiatric patients merits attention independent of other commonly assessed psychiatric symptoms such as anxiety, depression, and conventional distress, and how targeting suffering per se might add value to psychiatric patient care.

METHODS

Sources for this article were obtained via a selective literature search in PubMed using the terms "suffering" in the title and the terms "psychiatric disorder," "mental illness," "assessment," "measurement," "scale," "existential suffering," and "unbearable suffering." Articles of interest were followed up using a snowball technique to examine "similar articles" and "cited by" titles to find additional pertinent articles.

RESULTS

Definitions of suffering in the medical literature stress its subjectivity, particularity, complexity, and connection to a wide variety of noxious sensations, as well as real and anticipated deficits, losses, and thwarted motivations. These can affect the entire spectrum of universal human needs, from basic biological issues through intrapsychic, interpersonal, and social issues, encompassing existential concerns of meaning, purpose, and transcendence. Based on these factors, a definition of suffering in patients with psychiatric disorders is proposed. Although efforts to measure suffering have been limited and numerous gaps in the literature are evident, several scales may offer suitable bases for the study of suffering in patients with psychiatric disorders.

CONCLUSIONS AND IMPLICATIONS

Ascertaining sources of suffering may require new types of inquiry and additional time. Well-described, evidence-informed strategies and time-honored psychotherapy techniques are available for addressing the numerous concerns that contribute to suffering. Patients with psychiatric disorders whose distinct, multidimensional sources of suffering are identified, acknowledged, and addressed may experience better treatment quality, greater treatment satisfaction, and possibly better outcomes than those whose clinicians' attention is limited to conventional psychiatric signs and symptoms.

The effect of 5-min mindfulness of love on suffering and spiritual quality of life of palliative care patients: A randomized controlled study

OBJECTIVE

Suffering is a common experience in palliative care. In our study, we aimed to determine the effect of 5-min mindfulness of love on suffering and the spiritual quality of life of palliative care patients.

METHODS

We conducted a parallel-group, blinded, randomized controlled study at the University of Malaya Medical Centre (UMMC), Malaysia from February 2019 to April 2019. Sixty adult palliative care patients with an overall suffering score of 4/10 or above based on the Suffering Pictogram were recruited and randomly assigned to either the 5-min mindfulness of love group (N = 30) or the 5-min supportive listening group (N = 30).

RESULTS

There were statistically significant improvements in the overall suffering score (mean difference = -2.9, CI = -3.7 to -2.1, t = -7.268, p = 0.000) and the total FACIT-Sp-12 score (mean difference = 2.9, CI = 1.5 to 4.3, t = 4.124, p = 0.000) in the intervention group compared to the control group.

CONCLUSION

The results provided evidence that 5-min mindfulness of love could affect the actual state of suffering and the spiritual quality of life of palliative care patients.

The Effect of 5-Minute Mindfulness of Peace on Suffering and Spiritual Well-Being Among Palliative Care Patients: A Randomized Controlled Study

BACKGROUND

Mindfulness practices may have a role in reducing suffering and improving spiritual well-being among patients with serious illness. The efficacy, feasibility and acceptability of such interventions warrant further exploration in the palliative care population.

OBJECTIVE

To investigate the effect of a brief mindfulness practice, the 5-minute mindfulness of peace intervention, on suffering and spiritual well-being among palliative care patients.

METHODS

A randomized controlled study was conducted on adult palliative care patients with moderate to severe levels of suffering. Participants in the intervention arm were guided through a 5-minute mindfulness of peace exercise while participants in the control arm received 5 minutes of active listening. Pre- and post-intervention suffering and spiritual well-being were measured using the Suffering Pictogram and the FACIT-Sp-12 questionnaire, respectively.

RESULTS

40 participants completed the study. 5-minute mindfulness of peace significantly reduced suffering (median = -3.00, IQR = 2.00) more than 5 minutes of active listening (median = -1.00, IQR = 1.75), U = 73.50, z = -3.48, p = 0.001, η² = 0.31. FACIT-Sp-12 score also significantly improved in the intervention arm (median = +5.00, IQR = 2.75) compared with the control arm after 5 minutes (median = +1.00, IQR = 3.00), U = 95.50, z = -2.85, p = 0.004, η² = 0.21.

CONCLUSIONS

A brief 5-minute mindfulness of peace exercise is effective in providing immediate relief of suffering and improving spiritual well-being. It is a useful and feasible intervention among patients receiving palliative care for rapidly and momentarily reducing spiritual suffering.

The suffering measurement instruments in palliative care: A systematic review of psychometric properties

BACKGROUND

The relief of suffering is considered one of the main goals to reach at the end of life, and nurses play an essential role in the prevention and relief of suffering. Validated instruments for assessing suffering can be useful, and selection of the most appropriate measure is crucial. To date, no systematic review has been performed that contrasts the measurement properties of instruments assessing suffering in the palliative care population, according to the most up-to-date COnsensus-based Standards for the selection of health status Measurement INstruments methodology.

OBJECTIVES

The aim of this systematic review is twofold: (1) identify the measures assessing suffering in the palliative care population, and (2) assess the measurement properties of these measures.

DESIGN

A systematic review of the measurement properties of instruments assessing suffering in palliative care was carried out.

DATA SOURCES

The search strategy was conducted in Medline, CINAHL, PsycINFO, Web of Science, Cochrane Library, SciELO, Scopus, Cosmin database of systematic reviews and Open gray.

REVIEW METHODS

The following methodologies were applied: updated COnsensus-based Standards for the selection of health status Measurement INstruments, the Meta-Analysis of Observational Studies in Epidemiology, and the Assessing the Methodological Quality of Systematic Reviews tool. A protocol for this systematic review was registered in PROSPERO (Registration number: CRD42018106488). Eligible studies were those that satisfied the following criteria: a) validation studies of measures assessing suffering in the palliative care population, b) assessing at least one measurement property of a measure, c) published in English or Spanish and d) published between January 1980 and September 2019. The included studies were assessed for the methodological quality of the measurement properties and then compared in terms of both the measurement properties and the methodological quality of the processes used. The evidence for each measurement property was summarised and the quality of the evidence was graded using the Grading of Recommendations, Assessment, Development and Evaluation approach.

RESULTS

The search strategy yielded a total of nine studies and six instruments assessing suffering. The methodological quality of the studies was doubtful and the quality of the evidence was moderate for most of the measurement properties analysed. The Suffering Pictogram was the instrument with the best rating for methodological quality and quality of evidence, for most of the measurement properties evaluated.

CONCLUSIONS

Instruments assessing suffering in palliative care have been identified in this systematic review. The Suffering Pictogram seems to be the most useful instrument identified. Tweetable abstract: The relief of suffering is one of the main goals to reach at the end of life, and the selection of the most appropriate measure for assessing this construct is crucial.

Patterns of Suffering in Palliative Care: A Descriptive Study

Suffering experiences are common phenomena in palliative care. In this study, we aim to explore the different patterns of suffering in palliative care. Adult palliative care patients were recruited from the University of Malaya Medical Centre. Suffering scores were charted 3 times a day for a week. The characteristics of the suffering charts were analyzed using SPSS. The patterns of suffering were analyzed using structural pattern recognition. A total of 53 patients participated. The overall trends of suffering were downward (64%), upward (19%), and stable (17%). Median minimum and maximum suffering scores were 2/10 and 6/10, with an average of 3.6/10. Nine patterns of suffering were recognized from categorizing two key characteristics of suffering (intensity and fluctuation)-named S1 to S9. Understanding the different patterns of suffering may lead to better suffering management.

The Effect of 20-Minute Mindful Breathing on the Perception of Suffering and Changes in Bispectral Index Score (BIS) in Palliative Care Informal Caregivers: A Randomized Controlled Study

Informal caregivers are at risk of being overwhelmed by various sources of suffering while caring for their significant others. It is, therefore, important for caregivers to take care of themselves. In the self-care context, mindfulness has the potential to reduce caregiver suffering. We studied the effect of a single session of 20-minute mindful breathing on the perceived level of suffering, together with the changes in bispectral index score (BIS) among palliative care informal caregivers. This was a randomized controlled study conducted at the University of Malaya Medical Centre, Malaysia. Forty adult palliative care informal caregivers were recruited and randomly assigned to either 20-minute mindful breathing or 20-minute supportive listening. The changes in perceived suffering and BIS were measured preintervention and postintervention. The reduction in suffering score in the intervention group was significantly more than the control group at minute 20 ( U = 124.0, n1 = n2 = 20, mean rank1 = 24.30, mean rank2 = 16.70, z = −2.095, P = .036). The reduction in BIS in the intervention group was also significantly greater than the control group at minute 20 ( U = 19.5, n1 = n2 = 20, mean rank1 = 29.52, mean rank2 = 11.48, z = −4.900, P < .0001). Twenty minutes of mindful breathing was more efficacious than 20 minutes of supportive listening in the reduction in suffering among palliative care informal caregivers.

Pain and Suffering

OBJECTIVE

To review literature on the relationship of pain, spirituality, and suffering as it relates to the patient with cancer who is experiencing pain.

DATA SOURCES

Peer-reviewed articles, textbooks, internet.

CONCLUSION

Pain and suffering are distinct and yet closely related in patients with cancer. Oncology nurses are important in assessing a patient's pain, including dimensions of spirituality and suffering.

IMPLICATIONS FOR NURSING PRACTICE

Oncology nurses are the front line of pain management for patients. This includes recognizing existential distress and suffering and responding to suffering.

Suffering measurement instruments in palliative care: protocol for a systematic psychometric review

INTRODUCTION

The prevention and relief of suffering are regarded as a goal at the end of life; therefore, suffering assessment at the end of life is essential. In this regard, we need instruments that allow us to evaluate this construct for gathering more evidence, as the assessment of suffering is increasingly used in research and the clinical setting. Many measures have been designed to assess this construct, and the selection of the most appropriate instrument is crucial. The aims of this systematic review are to (1) identify the measures assessing suffering in patients with advanced disease and their psychometric properties and (2) evaluate the methodological quality of studies on measurement properties.

METHODS AND ANALYSIS

The protocol of this systematic review was developed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols Guidelines. A systematic psychometric review of measures assessing suffering in patients with advanced disease and their psychometric properties will be carried out according to the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN). The search strategy will be performed following the Peer Review of Electronic Search Strategies. Searches will be conducted in Cumulative Index to Nursing and Allied Health Literature, Medline, PsycINFO, Cochrane Library, SciELO, Open Grey, Scopus, Web of Science and COSMIN database of systematic reviews, and it will be limited by time (1980-2018) and language (only literature in English and Spanish). Literature will be evaluated by two independent reviewers according to the COSMIN checklist, and measurement properties data of each study that meet the inclusion criteria will be scored independently by two researchers according to COSMIN quality ratings.

ETHICS AND DISSEMINATION

Ethical approval is not necessary for systematic review protocols. The results will be disseminated by publication in a peer-reviewed journal and presented at a relevant conference.

The Effect of 20-Minute Mindful Breathing on the Perception of Suffering and Changes in Bispectral Index Score in Palliative Care Patients: A Randomized Controlled Study

A randomized controlled study was conducted to evaluate the efficacy of 20-minute mindful breathing in suffering reduction. Forty palliative care patients with an overall suffering score of 4 or above as measured with the Suffering Pictogram were recruited and randomly assigned to 20-minute mindful breathing or 20-minute supportive listening. There was statistically significant reduction of suffering score in both the groups. For Bispectral Index Score value, there was statistically significant difference between intervention and control. A 20-minute mindful breathing could be useful in the alleviation of suffering in palliative care.
