Delphi consensus on strategies in the management of opioid-induced constipation in cancer patients

Opioids and the Gastrointestinal Tract: The Role of Peripherally Active µ-Opioid Receptor Antagonists in Modulating Intestinal Permeability

Opioid receptors are found throughout the gastrointestinal tract, including the large intestine. Many patients treated with opioids experience opioid-induced constipation (OIC). Laxatives are not effective in most patients, and in those who do initially respond, the efficacy of laxatives generally diminishes over time. In addition, OIC does not spontaneously resolve for most patients. However, complications of opioids extend far beyond simply slowing gastrointestinal transit. Opioid use can affect intestinal permeability through a variety of mechanisms. Toll-like receptors are a crucial component of innate immunity and are tightly regulated within the gut epithelium. Pathologic µ-opioid receptor (MOR) and toll-like receptor signaling, resulting from chronic opioid exposure, disrupts intestinal permeability leading to potentially harmful bacterial translocation, elevated levels of bacterial toxins, immune activation, and increased cytokine production. Peripherally active MOR antagonists, including methylnaltrexone, are effective at treating OIC. Benefits extend beyond simply blocking the MOR; these agents also act to ameliorate opioid-induced disrupted intestinal permeability. In this review, we briefly describe the physiology of the gastrointestinal epithelial border and discuss the impact of opioids on gastrointestinal function. Finally, we consider the use of peripherally active MOR antagonists to treat disrupted intestinal permeability resulting from opioid use and discuss the potential for improved morbidity and mortality in patients treated with methylnaltrexone for opioid-induced bowel disorders.

Opioid-induced Constipation: Old and New Concepts in Diagnosis and Treatment

Daily use of opioid analgesics has significantly increased in recent years due to an increasing prevalence of conditions associated with chronic pain. Opioid-induced constipation (OIC) is one of the most common, under-recognized, and under-treated side effects of opioid analgesics. OIC significantly reduces the quality of life by causing psychological distress, lowering work productivity, and increasing access to healthcare facilities. The economic and social burden of OIC led to the development of precise strategies for daily clinical practice. Key aspects are the prevention of constipation through adequate water intake and fiber support, avoidance of sedentariness, and early recognition and treatment of cofactors that could worsen constipation. Recommended first-line therapy includes osmotic (preferably polyethylene glycol) and stimulant laxatives. Peripherally acting μ-opioid receptor antagonists, such as methylnaltrexone, naloxegol, or naldemedine, should be used in patients that have not responded to the first-line treatments. The bowel functional index is the main tool for assessing the severity of OIC and for monitoring the response. The paper discusses the recent literature on the pathophysiology, clinical evaluation, and management of OIC and provides a pragmatic approach for its assessment and treatment.

Educational intervention on perceived stress among adults with type 2 diabetes and metabolic syndrome: a non-randomized clinical trial

Objective

To evaluate the effectiveness of Virtual Teaching (VT) Programme regarding palliative care on knowledge, self-efficacy and attitude among Nursing Personnel working in selected hospitals of North India.

Methods

A quasi-experimental study with non-equivalent control group pre-test-post-test design was conducted on 121 Nursing Personnel, selected by convenient sampling technique. Knowledge, self-efficacy and attitude were assessed using structured knowledge questionnaire, Palliative Care Self-efficacy Scale, and Frommelt Attitudes toward care of dying scale respectively. Nursing personnel in experimental group received Virtual Teaching Programme regarding palliative care whereas those in comparison group received conventional teaching (CT). The study included a pre-test followed by the teaching (virtual/ conventional) on day one. The post-test was conducted on 15th day after the intervention.

Results

The results showed that there was a significant difference in mean post-test knowledge (VT group: 17.11 to CT group: 25.05; t=9.25, p<0.001), self-efficacy (VT group: 39.27 to CT group: 43.38; t=6.39, p<0.001) and attitude (VT group: 108.86 to CT group: 133.23; t=9.27, p<0.001) scores between virtual teaching group and conventional teaching group. ANCOVA test revealed statistically significant differences in the mean scores of knowledge [F (1.11) = 86.61, p<0.001], self-efficacy [F (1.11) = 841.75, p<0.001] and attitude [F (1.11) = 82.92, p<0.001] between the groups, with higher means obtained in the CT group.

Conclusion

Virtual Teaching programme and Conventional teaching both were effective in enhancing the knowledge, self-efficacy and attitude among Nursing Personnel regarding palliative care with conventional teaching being more effective.

Palliative care needs and barriers in an urban Ugandan Emergency Department: A mixed-methods survey of emergency healthcare workers and patients

Background

Palliative Care offers patient-centered, symptom-focused relief for patients with incurable disease, and early integration of palliative care ensures quality of life and death while reducing medical impoverishment. The Emergency Department is an ideal yet understudied, under-utilized location to initiate palliative care.

Objective

To evaluate the palliative care needs of patients with incurable disease and perceived barriers amongst healthcare providers in the Emergency Department of Kiruddu National Referral Hospital, Kampala, Uganda.

Methods

A mixed methods survey of Emergency Department healthcare workers and patients was conducted. A crosse sectional survey of ninety-nine patients was conducted using the integrated Palliative Care Outcome Scale (IPOS). Eleven interviews were conducted with healthcare workers at Kiruddu Hospital, identified by purposive sampling. Descriptive and inferential statistics were used to analyze quantitative data.. Grounded theory approach was used to construct the in depth interview questions, code and analyze qualitative results and collapse these results into final themes.

Results

The most common diagnoses were HIV/HIV-TB (32 %), heart disease (18 %), and sickle cell disease (14 %). The prevalence of unmet palliative care needs was substantial: more that 70 % of patients reported untreated symptoms e.g., pain, fatigue, difficulty breathing. Seventy-seven percent of the population reported severe or overwhelming pain. The main barriers to provision of palliative care in the Emergency Department as identified by healthcare workers were: (1) lack of adequate training in palliative care; (2) Challenges due to patient volume and understaffing; (3) the misconception that palliative care is associated with pain management alone; (4) Financial constraints as the greatest challenge faced by patients with incurable disease.

Conclusions

We report a high prevalence of unmet palliative care needs among patients in this urban Ugandan Emergency Department, and important barriers reported by emergency healthcare providers. Identification of these barriers offers opportunities to overcome them including harnessing novel mHealth interventions such as clinical support apps or telehealth palliative care consultants. Integration of palliative care in this setting would improve the care of vulnerable patients, provide healthcare workers with an additional care modality while likely adding value to the health system.

Toward Shared Decision-Making in Degenerative Cervical Myelopathy: Protocol for a Mixed Methods Study

BACKGROUND

Health care decisions are a critical determinant in the evolution of chronic illness. In shared decision-making (SDM), patients and clinicians work collaboratively to reach evidence-based health decisions that align with individual circumstances, values, and preferences. This personalized approach to clinical care likely has substantial benefits in the oversight of degenerative cervical myelopathy (DCM), a type of nontraumatic spinal cord injury. Its chronicity, heterogeneous clinical presentation, complex management, and variable disease course engenders an imperative for a patient-centric approach that accounts for each patient's unique needs and priorities. Inadequate patient knowledge about the condition and an incomplete understanding of the critical decision points that arise during the course of care currently hinder the fruitful participation of health care providers and patients in SDM. This study protocol presents the rationale for deploying SDM for DCM and delineates the groundwork required to achieve this.

OBJECTIVE

The study's primary outcome is the development of a comprehensive checklist to be implemented upon diagnosis that provides patients with essential information necessary to support their informed decision-making. This is known as a core information set (CIS). The secondary outcome is the creation of a detailed process map that provides a diagrammatic representation of the global care workflows and cognitive processes involved in DCM care. Characterizing the critical decision points along a patient's journey will allow for an effective exploration of SDM tools for routine clinical practice to enhance patient-centered care and improve clinical outcomes.

METHODS

Both CISs and process maps are coproduced iteratively through a collaborative process involving the input and consensus of key stakeholders. This will be facilitated by Myelopathy.org, a global DCM charity, through its Research Objectives and Common Data Elements for Degenerative Cervical Myelopathy community. To develop the CIS, a 3-round, web-based Delphi process will be used, starting with a baseline list of information items derived from a recent scoping review of educational materials in DCM, patient interviews, and a qualitative survey of professionals. A priori criteria for achieving consensus are specified. The process map will be developed iteratively using semistructured interviews with patients and professionals and validated by key stakeholders.

RESULTS

Recruitment for the Delphi consensus study began in April 2023. The pilot-testing of process map interview participants started simultaneously, with the formulation of an initial baseline map underway.

CONCLUSIONS

This protocol marks the first attempt to provide a starting point for investigating SDM in DCM. The primary work centers on developing an educational tool for use in diagnosis to enable enhanced onward decision-making. The wider objective is to aid stakeholders in developing SDM tools by identifying critical decision junctures in DCM care. Through these approaches, we aim to provide an exhaustive launchpad for formulating SDM tools in the wider DCM community.

Circumstances affecting patients' euthanasia or medically assisted suicide decisions from the perspectives of patients, relatives, and healthcare professionals: A qualitative systematic review

This study aims to explore circumstances affecting patients' euthanasia and medically assisted suicide (MAS) decisions from the perspectives of patients, relatives, and healthcare professionals. A qualitative systematic review was performed following PRISMA recommendations. The review protocol is registered in PROSPERO (CRD42022303034). Literature searches were conducted in MEDLINE, EMBASE, CINAHL Complete, Eric, PsycInfo, and citation pearl search in Scopus from 2012 to 2022. In total, 6840 publications were initially retrieved. The analysis included a descriptive numerical summary analysis and a qualitative thematic analysis of 27 publications, resulting in two main themes-Contexts and factors influencing actions and interactions, and Finding support while dealing with resistance in euthanasia and MAS decisions-and related sub-themes. The results illuminated the dynamics in (inter)actions between patients and involved parties that might both impede and facilitate patients' decisions related to euthanasia/MAS, potentially influencing patients' decision-making experiences, and the roles and experiences of involved parties.

An update on the use of pharmacotherapy for opioid-induced bowel dysfunction

INTRODUCTION

With the growing rate of aging and the incidence of chronic diseases, there has been an upsurge in opioid prescription and abuse worldwide. This has been associated with increased reports of opioid-related adverse events, particularly opioid-induced bowel dysfunction (OIBD), calling for a rational clinical management strategy.

AREAS COVERED

Through searching PubMed, Scopus, Cochrane Library, and Web of Science, English literature was gathered as of 1 January 2017. Furthermore, the USFDA, EMA, TGA, Clinicaltrials.Gov, WHO-ICTRP databases, and the latest guidelines were reviewed to extract ongoing clinical studies and provide an evidence-based expert opinion with detailed information on efficacy, safety, approval status, and pharmacokinetics of the currently used medications.

EXPERT OPINION

Despite the significant burden of OIBD, the clinical development of agents lags behind disease progress. Although in most places, management of opioid-induced constipation (OIC) is initiated by lifestyle modifications followed by laxatives, opioid antagonists, and secretagogue agents, there are still major conflicts among global guidelines. The fundamental reason is the lack of head-to-head clinical trials providing inter- and intragroup comparisons between PAMORAs, laxatives, and secretagogue agents. These investigations must be accompanied by further valid biopharmaceutical and economic evaluations, paving the way for rational clinical judgment in each context.

A Thematic Analysis of Dimensions of Spiritual Care

Background

An overview of spiritual care studies can help reveal the dimensions of spiritual care and summarize the findings of available studies. Thus, we designed the present study based on existing studies to explain the dimensions of spiritual care.

Materials and Methods

In this thematic analysis, we gathered the related articles published in Persian and English in the last 8 years (2013-2021) with the help of the keywords of Care, Support, Spirituality, Religion, Treatment, Hospice, and Palliative, and searching in electronic databases, including PubMed, Scopus, Web Of Sciences, Magiran, Islamic Science Citation (ISC), and Scientific Information Database (SID). We accurately studied 79 articles that met the inclusion criteria, and then the spiritual care components were extracted and coded, and finally, the codes were categorized as themes and sub-theme.

Results

Thematic analysis of available studies revealed that the dimensions (theme) of spiritual care include: spiritual and religious assessment, developing a structure for providing spiritual care, establishing effective and supportive communication with the patient, training the patient, answering his questions, encouraging, maintaining, and improving social communications, encouraging the patient to live happily, helping the patient to achieve peace and calmness, supporting for spiritual rituals and activities, supporting and training the patient's family, and supporting the dying patient.

Conclusions

Spiritual care includes various and numerous dimensions. Considering the widespread dimensions of spiritual care, it seems necessary to design and plan appropriate studies to reveal other spiritual care dimensions from the perspective of patients and care providers in different cultures.

Palliative care in home health care services and hospitals - the role of the resource nurse, a qualitative study

BACKGROUND

The role of the resource nurse aims at bridging the gap between the specialist nurses and the nurses who work in non-specialist wards. The role is established internationally and used in a wide area of clinical settings. The resource nurse is promoting evidence-based practice. Patients with life limiting conditions including cancer and other chronic diseases will likely need palliative care during the trajectory of illness. Due to the complexity of palliative care, both interprofessional help and cooperation between levels of healthcare are considered necessary.

AIM

The aim of this study was to explore the perceptions and experiences related to the role of the resource nurse in palliative care in the setting of home health care services and hospitals in Norway, from the perspectives of the resource nurses and the ward nurses.

DESIGN

The study has an explorative design with a qualitative approach.

METHODS

Eight individual interviews were conducted. Audiotaped interview material was transcribed verbatim and the data were analysed using systematic text condensation. The encoded data material provided the basis for writing analytical texts that in turn resulted in meaningful descriptions of the different categories.

RESULTS

Four resource nurses and four ward nurses participated in individual interviews. Analysis of the data yielded three categories: 1. Expectations of better competence in the ward. 2. Expectations of better cooperation between professions and different levels of healthcare services. 3. Improvements and hindrances.

CONCLUSION

The resource nurse role is underutilized due to heavy workload and inefficient organization of care. Improvements such as sufficient time resources, support from the ward nurse and cooperation with staff nurses, the resource nurses' role could contribute to increased competence and cooperation interprofessionally and between levels of healthcare.

Psychometric Properties of the Persian Version of Palliative Care Outcome Scale (POS) in Adult Patients With Cancer

Background

Measuring the outcomes of palliative care plays an important role to improve the quality, efficiency, and availability of these services in patients with cancer. Using valid, reliable, and culturally appropriate tools has a considerable role to measure these outcomes. This study aimed to assess the psychometric properties of the translated version of the Palliative care Outcome Scale (POS).

Methods

This methodological study was conducted in two outpatient clinics related to Shohada Tajrish and Baqiyatallah hospitals in Tehran in 2019-2020. The translation was done using the Forward-Backward approach after gaining permission from the developer. Face validity was tested with 10 patients with cancer through cognitive interviewing, as well as content validity with four experts. Construct validity was performed by (n = 203) exploratory factor analysis and confirmation (N = 150). To assess the reliability, internal consistency was assessed by using Cronbach's alpha coefficient, and relative stability was assessed using the interclass correlation coefficient (ICC). Furthermore, interpretability and ceiling and floor effects were assessed.

Results

A total of 353 patients with cancer under palliative care were included in the study. Then, three psychological (30%), physical (12.25%), and social factors (12.08%) with a cumulative variance of 54.34% were extracted in exploratory factor analysis. Confirmatory factor analysis showed that the model has a good fit of information. Cronbach's alpha coefficient for scale was 0.719. Furthermore, the ICC was 0.812. The scale was interpretable, and ceiling and floor effects were 0%.

Conclusion

Persian version of the POS was evaluated as a valid and reliable tool. Therefore, it can be used by the clinician to monitor the consequences of palliative care in Iranian cancer patients.

Constipation in Cancer Patients - an Update of Clinical Evidence

OPINION STATEMENT

Constipation is one of the most frequent problems in cancer patients, and its etiology is multifactorial. It leads to decreased quality of life and impedes optimal pain treatment. Despite the high prevalence, constipation is frequently underdiagnosed mainly because of lack of validated diagnostic criteria or widely accepted definition of constipation in cancer patients. All cancer patients should be evaluated regularly for constipation, and concomitant causes and risk factors were assessed. Opioids are responsible for a much of the secondary constipation in cancer patients. The management of constipation in cancer patients should be multifaceted, addressing dietary and behavioral issues and optimizing pharmacological interventions. Prevention of opioid-induced constipation (OIC) is pivotal, as treatment is often unsatisfactory or inefficient. Dietary and behavioral interventions should be considered. Non-pharmacological measures include hydration and nutrition, ensuring privacy during defecation, using a commode or footstool, and the availability of a caregiver. Abdominal massage may be of value. Traditional laxatives are recommended in prevention but not in the treatment of OIC. Peripherally acting mu-opioid receptor antagonists (PAMORA) appear the first choice in the treatment and an alternative to laxatives in some recent clinical practice guidelines in preventing OIC. Naldemedine, naloxegol, and methylnaltrexone are supported by quality evidence for OIC management. Naloxone or naltrexone, taken orally in combined formulations with opioids, may be valuable in preventing or reducing OIC symptoms.

Risk factors for opioid-induced constipation in cancer patients: a single-institution, retrospective analysis

PURPOSE

To identify risk factors for opioid-induced constipation (OIC).

METHODS

This study retrospectively analyzed 175 advanced cancer patients who were receiving pain treatment with opioids and were newly prescribed laxatives for OIC at Seirei Hamamatsu General Hospital between November 2016 and June 2021. For the regression analysis of factors associated with OIC, variables were extracted manually from clinical records. The effect of newly prescribed laxatives for OIC was evaluated as "effective" in cases where the number of spontaneous bowel movements increased at least once in the first 3 days. The OIC was defined based on Rome IV diagnostic criteria. Multivariate logistic regression analysis was performed to identify risk factors for OIC. Optimal cutoff thresholds were determined using receiver operating characteristic analysis. Values of P < 0.05 (two-tailed) were considered significant.

RESULTS

Significant factors identified included body mass index (BMI) (odds ratio [OR] = 0.141, 95% confidence interval [CI] = 0.027-0.733; P = 0.020), chemotherapy with taxane within 1 month of evaluation of laxative effect (OR = 0.255, 95% CI = 0.068-0.958; P = 0.043), use of naldemedine (OR = 2.791, 95% CI = 1.220-6.385; P = 0.015), and addition or switching due to insufficient prior laxatives (OR = 0.339, 95% CI = 0.143-0.800; P = 0.014).

CONCLUSION

High BMI, chemotherapy including a taxane within 1 month of evaluation of laxative effect, no use of naldemedine, and addition or switching due to insufficient prior laxatives were identified as risk factors for OIC in advanced cancer patients with cancer pain.

Strategies for knowledge translation of a palliative approach outside specialized palliative care services: a scoping review

Objectives

Research suggests palliative care to be translated and integrated in non-specialized palliative care services throughout the palliative care continuum across populations and settings. A need has been identified to build on the existing research literature in order to design strong knowledge translation strategies that can be evaluated in future research. The aim was to map strategies for knowledge translation of a palliative approach to care into non-specialized palliative care services for adult patients. The objectives were to explore the primary research activities, the specific type of knowledge translation strategies used, the research designs and study settings for such evaluations along with the major results thereof, and to identify major research gaps in this area.

Methods

A scoping review was performed to map the volume and characteristics of research literature (project registered in PROSPERO #2018 CRD42018100663). The ten-year period 2010 to 2019 was searched in six major databases for original articles published in English in which the knowledge translation of a palliative approach for adult patients was evaluated in non-specialized palliative healthcare settings, and all type of empirical data-based research designs. We excluded non-English, non-empirical articles, non-evaluation of knowledge translations, specialized palliative care settings, and other types of publications (i.e. non-original articles).

Results

Most of the 183 included articles focused on patients with cancer who were dying in hospitals and in high income countries. Only 13 articles focused on early palliative care. A palette of different strategies was used to implement palliative care in non-specialist palliative settings; no strategy was identified as outstanding. The majority of the articles had unspecified essential components of the research designs.

Conclusion

Previous suggestions for utilization of implementation science for knowledge translation of a palliative approach to care into non-specialized palliative care services are confirmed, and established knowledge translation theories can strengthen the field. To advance this specific field of knowledge, meticulously detailed reporting of studies is required as related to research designs, clarifications of contextual influences and mechanisms at work. Specific systematic reviews and meta-syntheses in the field are merited.

Opioid-Induced Constipation in Advanced Cancer Patients

The present study discusses opioid-induced constipation (OIC) in advanced cancer patients, focusing on the OIC definition, pathophysiology, and treatment. OIC is any change from baseline defecation patterns and bowel habits that developed after starting opioid therapy. The condition is characterized by bowel frequency reduction, worsening or development of straining, a sensation of incomplete defecation, or distress associated with bowel habits. OIC is common in advanced cancer patients, with a prevalence of approximately 51%-87% in patients taking opioids for pain management. Patients are likely to experience severe distress, work productivity reduction, poor quality of life, and increased healthcare utilization. OIC has a complex pathophysiology that involves propulsive and peristalsis impairment, intestinal mucosal secretion inhibition, intestinal fluid absorption enhancement, and anal sphincters function impairment. The Rome III criteria are used to assess and diagnose clinical OIC and can also be diagnosed through the Patient Assessment of Constipation (PAC) measures, including the symptom survey (PAC-SYM) and quality of life survey (PAC-QOL). Non-pharmacological treatment of OIC involves lifestyle habits and dietary adjustments, although these interventions might be insufficient to manage the condition. Pharmacological treatments involve the use of traditional laxatives and newer agents like peripherally acting mu-opioid receptor agonists (PAMORAs), including naldemedine, naloxegol, and methylnaltrexone. More novel treatments for OIC that target the pathophysiology are still needed and should be studied carefully for safety and efficacy.
