Guided Imagery for Symptom Management of Patients with Life-Limiting Illnesses: A Systematic Review of Randomized Controlled Trials.

Background: Patients with life-limiting illnesses receiving palliative care have a high symptom burden that can be challenging to manage. Guided imagery (GI), a complementary and integrative therapy in which patients are induced to picture mental images with sensory components, has proven in quasi-experimental studies to be effective as a complementary therapy for symptom management. Objective: To systematically review randomized controlled trials that report evidence of guided imagery for symptom management in patients with life-limiting illnesses. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline was followed for this review and the search strategy was applied in Medline, CINHAL, and Web of Science. The quality of articles was evaluated using the Cochrane Collaboration's Risk-of-Bias Tool 2 (RoB 2). The results are presented using the Guidance on the Conduct of Narrative Synthesis in Systematic Reviews. Results: A total of 8822 studies were initially identified through the search strategy, but after applying exclusion criteria, 14 randomized controlled trials were included in this review. The quality assessment revealed that four studies had a high risk of bias, nine had some concerns, and one had a low risk of bias. Out of the 14 studies, 6 evaluated oncological diagnosis, while the remaining 8 focused on nononcological diagnoses across 6 different diseases. GI was found to be effective in managing symptoms in 10 out of the 14 studies. Regardless of the disease stage, patients who received guided imagery experienced relief from anxiety, depression, pain, sleep disturbances, and fatigue. Conclusion: GI therapy has shown promising results regarding symptom management in palliative care patients with life-limiting illnesses at different stages.

Toma de decisiones para la adecuación del esfuerzo terapéutico al final de la vida en pacientes oncológicos del instituto Nacional de Cancerología de Colombia

Propósito: la adecuación del esfuerzo terapéutico es una decisión clínica basada en la evidencia que pretende evitar la futilidad médica. Se han señalado diferentes factores que pueden influir en esta toma de decisiones los cuales se relacionan con el paciente, el profesional médico que toma de las decisiones, barreras del sistema, cultura y economía, entre otros. El presente estudio pretende identificar aquellos factores que influyen en los médicos especialistas que laboran en la institución referente del cáncer en Colombia, a fin de planear acciones que mejoren el abordaje de la toma de decisiones con respecto a la adecuación del esfuerzo terapéutico en pacientes con cáncer. Metodología: diseño cualitativo basado en 13 entrevistas en profundidad a médicos especialistas del Instituto Nacional de Cancerología de Colombia. Resultados: participaron 3 mujeres y 10 hombres, con un promedio de edad de 36 años, 7 pertenecientes a la especialidad de oncología de adultos, 2 a oncohematología pediátrica, 1 a cuidados intensivos de adultos y 3 a cuidados intensivos pediátricos. Los factores hallados se agruparon en cuatro categorías: 1) conocimiento, 2) aspectos relacionados con la toma de decisiones, 3) quién decide, 4) tipo de decisión que se toma; a su vez, estas categorías se agruparon en temas que hacen alusión a los factores que influyen en la toma de decisiones de los especialistas para adecuar los esfuerzos terapéuticos. Conclusión: la adecuación de los esfuerzos terapéuticos es importante para evitar procedimientos médicos fútiles que prolonguen el sufrimiento. Se evidenciaron algunos factores que influyen en la toma de decisiones de los especialistas: falta de preparación de los profesionales de salud en el tema de toma de decisiones al final de la vida, uso reducido de escalas que permitan mejorar la información del pronóstico y desconocimiento sobre voluntades anticipadas; estos son algunos de aquellos factores que deben fortalecerse para generar acciones que mejoren el abordaje de esta temática.

Purpose: Adjusting therapeutic efforts is an evidence-based clinical decision that aims to avoid medical futility. Varied factors that can influence this decision-making have been pointed out, related to the patient, the medical professional who makes the decisions, system barriers, culture, and the economy, among others. The present study aims to identify those factors that help the specialists working in a cancer referral institution in Colombia to plan actions that improve the approach to decision-making regarding the adequacy of therapeutic efforts in cancer patients. Methodology: This qualitative design is based on 13 in-depth interviews with Colombia's National Cancer Institute specialists. Results: Three women and ten men participated, with an average age of 36 years; seven belonged to the specialty of adult oncology, two to pediatric oncohematology, one to adult intensive care, and three to pediatric intensive care. The factors found were grouped into four categories: 1) knowledge, 2) aspects related to decision-making, 3) the decision-maker, and 4) the type of decision made. These categories were clustered into themes that allude to the factors swaying specialists' decision-making to adjust therapeutic efforts. Conclusion: Adjusting therapeutic actions is vital to avoid futile medical procedures that prolong suffering. Some factors that influence the specialists' decision-making were noted: lack of preparation of health professionals on end-of-life decision-making, reduced use of scales to improve prognostic information, and ignorance about advance directives. These factors must be strengthened to improve the approach to this issue.

Subcutaneous Administration of Medications and Fluids by Nonprofessional Caregivers at Home.

Background: Patients requiring home-based palliative care have advanced complex illnesses with functional limitations and decline. This retrospective study reviewed caregiver administration of subcutaneous (SQ) medications and fluids when symptom control could not be achieved using the oral route. Methods: Medical records from September 1, 2017 to February 28, 2018 were reviewed for 272 consecutive patients who received SQ administration of medications or fluids at a home-based palliative care program. We analyzed the clinical characteristics of patients and caregivers, medications administered, and catheter outcomes. Results: Patients' median age was 74 years, and 163 (60%) were women. The most common cancer diagnoses were stomach 26 (12%), lung 22 (10%), and colorectal 20 (9%). Dementia 24 (44%), cerebrovascular disease 9 (16%), and congestive heart failure 7 (13%) were the most frequent nonmalignant diseases. Poor symptom control 162 (60%) and impaired oral intake 107 (39%) were the most common indications for an SQ route of administration. Nonprofessional caregivers trained by a nurse administered medications to 218 patients (80%). During interventions, the patients received a mean of 4 medications (±2 standard deviation). A total of 903 catheters were inserted, 15/732 (2%) catheters handled by nonprofessional caregivers caused a local infection, compared with 3/171 (1.8%) of catheters handled by nurses. Hydromorphone was the most common opioid used (57%), followed by morphine (35%). The median length of stay in the program was 24 days (interquartile range: 11-60). Conclusions: SQ administration of medications and fluids by nonprofessional caregivers trained by health care professionals is feasible and promising, but additional testing is needed.

A Systematic Review on Cannabinoids for Neuropathic Pain Administered by Routes Other than Oral or Inhalation.

The use of cannabis and cannabinoid products for the treatment of neuropathic pain is a growing area of research. This type of pain has a high prevalence, limited response to available therapies and high social and economic costs. Systemic cannabinoid-based therapies have shown some unwanted side effects. Alternative routes of administration in the treatment of neuropathic pain may provide better acceptance for the treatment of multiple pathologies associated with neuropathic pain. To examine the efficacy, tolerability, and safety of cannabinoids (individualized formulations, phytocannabinoids, and synthetics) administered by routes other than oral or inhalation compared to placebo and/or conventional medications in the management of neuropathic pain. This systematic review of the literature reveals a lack of clinical research investigating cannabis by routes other than oral and inhalation as a potential treatment for neuropathic pain and highlights the need for further investigation with well-designed clinical trials. There is a significant lack of evidence indicating that cannabinoids administered by routes other than oral or inhaled may be an effective alternative, with better tolerance and safety in the treatment of neuropathic pain. Higher quality, long-term, randomized controlled trials are needed to examine whether cannabinoids administered by routes other than inhalation and oral routes may have a role in the treatment of neuropathic pain.

Availability and accessibility of opioids for pain and palliative care in Colombia: a survey study / Disponibilidad y accesibilidad de los opioides para manejo del dolor y cuidado paliativo en Colombia: estudio tipo encuesta

Abstract Introduction: Access to essential medicines, including opioids, is a component of the right to health. Objective: To identify barriers to opioid availability and accessibility for pain and palliative care. Methods: Online survey with Colombian prescribers. Availability barriers were analyzed for each facility (distribution and/or dispensing). Accessibility barriers were analyzed by type. Descriptive analyses were conducted using relative frequencies. Significance within categories and regions was measured using Fisher's exact test. Results: Out of 1,208 prescribers invited, 806 (66.7%) completed the survey. Availability: 76.43% reported barriers. The most cited barrier was "Pharmacies authorized by health insurance companies", where opioids are frequently unavailable. Accessibility: 74.6% reported barriers. Most frequently cited was "Difficulty securing payment authorization for medication from health insurance companies". Significant differences were observed in terms of regions and "Cost" (p=0.02). Lack of coordination among procuring and distributing agencies affects availability. Limited awareness and bureaucratic procedures affect accessibility. Conclusions: There are barriers to opioid availability and access in Colombia, related to the existing structure for guaranteeing equitable supply. From the perspective of healthcare providers, problems related to pharmacy availability, prescription and cost of medicines hinder pain treatment.

Resumen Introducción: El acceso a medicamentos esenciales, incluidos los opioides, es un componente del derecho a la salud. Objetivo: Identificar las barreras de disponibilidad y acceso a los opioides para dolor y cuidados paliativos. Métodos: Encuesta virtual a prescriptores colombianos. Las barreras de disponibilidad se analizaron para cada centro (distribución y/o dispensación) y las barreras de acceso se analizaron por tipo. Los análisis descriptivos se realizaron utilizando frecuencias relativas. La significancia dentro de categorías y regiones se midió utilizando la prueba exacta de Fischer. Resultados: De los 1208 prescriptores invitados, 806 (66.7%) respondieron la encuesta. Disponibilidad: el 76,43% reportó barreras. La barrera más citada fue la relacionada con las "farmacias autorizadas por las aseguradoras de salud", donde los opioides con frecuencia no están disponibles. Acceso: el 74,6% reportó barreras. Se citó con mayor frecuencia la "Dificultad para obtener la autorización de pago de medicamentos por parte de las aseguradoras". Se observaron diferencias significativas entre regiones y "costos" (p=0,02). La falta de coordinación entre las entidades de adquisición y distribución afecta la disponibilidad. La limitada conciencia y los procedimientos burocráticos afectan la accesibilidad. Conclusiones: Existen barreras de disponibilidad y acceso a los opioides en Colombia, las cuales están relacionadas con la estructura disponible para garantizar un suministro equitativo. Desde el punto de vista de los prescriptores, los problemas relacionados con la disponibilidad de las farmacias, la prescripción y el costo de los medicamentos, obstaculizan el tratamiento adecuado del dolor.

The Development of Palliative Care in Colombia: An Analysis of Geographical Inequalities Through the Application of International Indicators.

CONTEXT: The national evaluation of an individual country is a tool used to improve the universal provision of palliative care. The evaluation of a country's internal situation, by means of an analysis of the development of palliative care by region, may also be an instrument for improvement. OBJECTIVES: The aim of this study was to understand the regional development of palliative care in Colombia, through the application of international indicators. METHODS: Regional development was analyzed for Colombia, with a country-specific adaptation of the evaluation method used in the latest edition of the Palliative Care World Map (Clark D, 2020), the need for palliative care per death with serious health-related suffering (Knaul FN, 2019), and the coverage of specialized services, following European standards (Centeno, 2016). A total of 33 of the country's regions were classified. RESULTS: Some 41% of the people who die in Colombia need palliative care. The average figure for specialized services is 0.5/100,000 inhabitants, with a maximum coverage of 51%. In Colombia, there are 12 regions with a generalized level of provision; six regions with isolated provision, nine regions developing their capacity, four with no known activity, and two at an advanced level of palliative care integration. The regions with the highest level of palliative care development coincide with higher demand and coverage of specialized services. CONCLUSION: Regional palliative care development is unequal and unbalanced. Applying international indicators to levels of regional development allows for the identification of geographical inequalities and highlights low palliative care development, especially in the rural areas of the country.

Recomendaciones basadas en evidencia para el manejo del dolor oncológico (revisión de la literatura) / Evidence-based recommendations for the management of cancer pain (review of the literature)

Resumen: Objetivo: Describir recomendaciones basadas en evidencia para el manejo integral del dolor oncológico. Metodología: Revisión temática basada en una búsqueda de guías de práctica clínica para el manejo integral del dolor oncológico, desde el 2012 al 2017. De las referencias incluidas, se recolectó información relacionada con la evaluación, clasificación, indicaciones de tratamiento, principios de manejo farmacológico y no farmacológico. Resultados: Se incluyeron 12 estudios relacionados con el manejo del dolor oncológico, después de la eliminación de duplicados. Se realizó una síntesis y análisis de aspectos relevantes enfocados en: 1) evaluación del dolor; 2) clasificación del dolor oncológico; 3) principios y metas de manejo del dolor, así como el tratamiento farmacológico y no farmacológico; y 4) seguimiento. Se recomienda que los pacientes con dolor leve (puntaje de 1 a 3) que no hayan sido tratados con opioides previamente, sean tratados con acetaminofén o antiinflamatorios no esteroideos (AINEs). Para pacientes con dolor leve que no responden a analgésicos no opioides y para pacientes con intensidad del dolor mayor o igual a 4, se recomiendan opioides de acción corta. Conclusión: El dolor oncológico inadecuadamente tratado constituye un problema de salud pública, por lo que es primordial una adecuada evaluación para asegurar de manera oportuna un manejo efectivo desde el diagnóstico, seguimiento a intervalos regulares y cuando se inicie un nuevo tratamiento.

Abstract: Objective: To describe the evidence-based recommendations for the integral management of oncological pain. Methodology: Literature review based on a search of clinical practice guidelines for the comprehensive management of oncological pain, from 2012 to 2017. From the included references, it was obtained information related the evaluation, classification, indications of treatment, principles of pharmacological management and not pharmacological. Results: We included 12 studies related for the management of oncological pain, after the elimination of duplicates. The synthesis and analysis of relevant aspects focused on 1) pain assessment; 2) classification of oncological pain; 3) principles and goals of pain management, as well as pharmacological and non-pharmacological management; and 4) follow-up. It is recommended that patients with mild pain (score of 1 to 3) who have not been previously treated with opioids, should be treated with acetaminophen or NSAIDs. For patients with mild pain who do not respond to non-opioids and for patients with pain intensity greater than or equal to four, short-acting opioids are recommended. Conclusion: Oncological pain inadequately treated constitutes a public health problem, which is why adequate evaluation is essential to ensure proper management from the moment of diagnosis, with follow-up at regular intervals and when a new treatment is initiated, in order to find best balance between efficacy and safety of the interventions, and maximizing functionality and improving the patient's quality of life. The management of oncological pain therefore requires a multidisciplinary approach.

Improving availability of and access to opioids in Colombia: description and preliminary results of an action plan for the country.

Latin America consumes less than 2.7% of the morphine in the world, as reported by the governments to the International Narcotics Control Board. Methods to improve access to opioids for the treatment of pain have been developed by the Pain & Policy Studies Group (PPSG), a World Health Organization Collaborating Center at the University of Wisconsin. This article describes the preparation and implementation of an action plan in Colombia as a part of an international fellowship program on opioid policy developed by the PPSG and funded by the Open Society Institute. The action plan for Colombia included three steps: 1) a survey of regulators and health care providers to identify the current situation and their perceptions of opioid availability in the regions of the country; 2) a workshop with representatives of the Ministry of Health, the national and state competent authorities, pain and palliative care physicians, and international leaders; and 3) implementation workshops at the local level throughout the country. For the survey, response rates of 47% and 96% were registered among physicians and competent authorities, respectively. The survey identified significant regional differences in perceived opioid availability between physicians and regulators. Focus group discussions during the workshop identified several reasons leading to limited availability of opioids in the country, including deficiencies in the procurement process, insufficient human resources, excessive bureaucratic tasks, insufficient number of pharmacies authorized to dispense controlled medications in the country, lack of training in the health care professions, and overly restrictive laws and regulations governing opioid availability. The third step of the action plan has not been implemented. Additional and continuous monitoring needs to be implemented to measure the progress of this project.
