Placebo Use in Pain Management: A Mechanism-Based Educational Intervention Enhances Placebo Treatment Acceptability.

ABSTRACT: Health care providers use treatments whose effectiveness derives partially or completely from 'nonspecific' factors, frequently referred to as placebo effects. Although the ethics of interventional placebo use continues to be debated, evidence suggests that placebos can produce clinically meaningful analgesic effects. Burgeoning evidence suggest that patients with chronic pain might be open to placebo treatments in certain contexts despite limited knowledge of their well-established psychoneurobiological underpinnings. In this investigation we sought to examine the effects of a brief, mechanism-based placebo analgesia educational intervention on aspects placebo knowledge and acceptability. Participants with chronic musculoskeletal pain completed a web-based survey in which they rated their knowledge of placebo analgesia, assessed placebo acceptability across different medical contexts, and evaluated 6 unique patient-provider treatment scenarios to assess the role of treatment effectiveness and deception on patient-provider attributions. Using a pre-post design, participants were randomized to receive either a placebo educational intervention or an active control education. Results showed that the educational intervention greatly improved perceptions of placebo knowledge, effectiveness, and acceptability, even in deceptive treatment contexts. This was the first study of its kind to show the value of an educational intervention in increasing openness to and knowledge of placebo analgesic interventions among patients with chronic musculoskeletal pain.In this we article highlight how patients with chronic pain might be open to placebo interventions, particularly adjunct and/or complementary treatments, when provided education on the neurobiological and psychological mechanisms that underlie placebo effects. Study findings highlight ethically acceptable ways to potentially use placebo factors to enhance existing pain treatments and improve patient health outcomes.

Project description:ObjectiveDespite years of research and the development of countless awareness campaigns, the number of deaths related to prescription opioid overdose is steadily rising. Often, naive patients undergoing trauma-related surgery are dispensed opioids while in the hospital, resulting in an escalation to long-term opioid misuses. We explored the impact of an educational intervention to modify perceptions of opioid needs at the bedside of trauma inpatients in post-surgery pain management.Materials and methodsTwenty-eight inpatients with acute post-surgical pain completed this proof-of-concept study adopting an educational intervention related to opioids and non-pharmacological strategies in the context of acute post-surgical pain. An education assessment survey was developed to measure pre- and post-education perceptions of opioid needs to manage pain. The survey statements encompassed the patient's perceived needs for opioids and other pharmacological and non-pharmacological therapeutics to manage acute pain. The primary outcome was the change in the patient's perceived need for opioids. The secondary (explorative) outcome was the change in Morphine Milligram Equivalents (MME) used on the day of the educational intervention while inpatients and prescribed at the time of the hospital discharge.ResultsAfter the educational intervention, patients reported less agreement with the statement, "I think a short course of opioids (less than 5 days) is safe." Moreover, less agreement on using opioids to manage trauma-related pain was positively associated with a significant reduction in opioids prescribed at discharge after the educational intervention. The educational intervention might have effectively helped to cope with acute trauma-related pain while adjusting potential unrealistic expectancies about pain management and, more in general, opioid-related needs.ConclusionThese findings suggest that trauma patients' expectations and understanding of the risks associated with the long-term use of opioids can be modified by a short educational intervention delivered by health providers during the hospitalization. Establishing realistic expectations in managing acute traumatic pain may empower patients with the necessary knowledge to minimize the potential of continuous long-term opioid use, opioid misuse, and the development of post-trauma opioid abuse and/or addiction.

Project description:Background and objectivesThe intersection of race, gender, and age puts older African American women at high risk of experiencing comorbid pain and depressive symptoms. The purpose of this study was to assess the feasibility and acceptability of a 12-week behavioral activation intervention to target self-selected goals related to pain and depressive symptoms in middle-aged and older African American women.Research design and methodsThis randomized waitlist control study included 34 self-identified African American women, 50 years of age or older, with moderate-to-severe chronic pain and depressive symptoms. The intervention consisted of 8 in-person or virtual 1-hour visits with a nurse. Follow-up acceptability assessments were conducted with 10 participants.ResultsThe average age of the participants was 64.8 (standard deviation [SD] 10.5). They reported an average pain intensity score of 7.0 (SD 1.9) out of 10 and an average Patient Health Questionnaire-9 depressive symptoms score of 11.9 (SD 4.0) at baseline. Of the 34 participants who consented, 28 (82.4%) women started the intervention and 23 (82.1%) completed the intervention. Participants described the study as useful and beneficial. Participants recommended including a group component in future iterations. Effect sizes at 12 weeks were -0.95 for depressive symptoms indicating a substantial decrease in experienced depressive symptoms, but pain intensity was virtually unchanged (+0.09).Discussion and implicationsThe findings of this study demonstrate that the intervention is acceptable among middle-aged and older African American women and their personal goals were met. Including a group component and identifying effective ways to decrease attrition rates will be key in the next steps of development for this intervention. It is crucial to provide tailored, nonpharmacological approaches to pain, and depression symptom management in older adult populations who experience inequities in pain and mental health outcomes. This study emphasizes the importance of participant-driven goal-setting interventions.

Project description:Registered Nurses (RNs) play an important role in caring for patients suffering from cancer pain. A lack of knowledge regarding pain management and the RNs' own perception of cancer pain could act as barriers to effective pain management. Educational interventions that target RNs' knowledge and attitudes have proved promising. However, an intervention consisting of evidence-based practice is a multifaceted process and demands behavioural and cognitive changes to sustain the effects of the intervention. Therefore, our study aimed to investigate if a theory-based educational intervention could change RNs' knowledge and attitudes to cancer pain and pain management, both four and 12 weeks after the start of the intervention.A quasi-experimental design with non-equivalent control groups was used. The primary outcome was measured using a modified version of the instrument Nurses' Knowledge and Attitudes Survey Regarding Pain (NKAS) at baseline, four weeks and 12 weeks after the start of the intervention to evaluate its persistence. The intervention's educational curriculum was based on the principles of Ajzen's Theory of Planned Behaviour and consisted of interactive learning activities conducted in workshops founded on evidence-based knowledge. The RN's own experiences from cancer pain management were used in the learning process.The theory-based educational intervention aimed at changing RNs knowledge and attitudes regarding cancer pain management measured by primary outcome NKAS resulted in a statistical significant (p<0.05) improvement of total mean score from baseline to four weeks at the intervention ward.The findings of this study, suggest that a theory-based educational intervention focused at RNs can be effective in changing RN's knowledge and attitudes regarding cancer pain management. However, the high number of dropouts between baseline and four weeks needs to be taken into account when evaluating our findings. Finally, this kind of theory-based educational intervention with interactive learning activities has been sparsely researched and needs to be evaluated further in larger projects.Clinical Trials.

Project description:ABSTRACT.Objective: Noncardiac chest pain is common and can cause distress, impair quality of life, and lead to recurrent evaluation. It is often multifactorial in etiology and influenced by psychological factors. The objective of this study was to describe the development, implementation, and preliminary feasibility of an 8-week multicomponent care management intervention.Methods: Participants with noncardiac chest pain were recruited from primary care clinics, ambulatory cardiac stress testing, and the emergency department (ED) at an urban academic hospital from March 2019 to November 2019. The care management team consisted of a nurse, cardiologist, and psychiatrist. Following a 1-time consultation visit with the cardiologist and nurse, evaluation and treatment recommendations were conveyed to the participant's primary care physician. The nurse completed 8 weekly phone calls with the participant to provide support, introduce therapeutic principles, and assist with care coordination under the supervision of a psychiatrist. Intervention feasibility was assessed on 7 domains. To examine preliminary efficacy, the number of ED visits was recorded, and participants completed pre-post measures of psychological health and health-related quality of life and Likert scales of chest pain symptom severity, frequency, and impact.Results: The intervention was developed and implemented in 3 patients who completed 100% of the consultation visits and a mean of 95.8% of study phone calls. There were no adverse events or ED visits. Mean scores for chest pain severity, chest pain frequency, chest pain impact, depression, anxiety, and somatization all improved. No other trends were observed.Conclusions: The findings suggest that a care management intervention may be feasible with potential to improve chest pain symptoms and psychological outcomes. A larger, randomized trial is needed to explore the efficacy of this intervention.Trial Registration: ClinicalTrials.gov identifier: NCT04904198.

Project description:BackgroundChronic low back pain can lead to individual suffering, high medical expenditures, and impaired social well-being. Although the role of physical activity in pain management is well established, the underlying mechanisms of biological and clinical outcomes are unknown. This study aimed to assess the feasibility and acceptability of a pain self-management intervention, Problem-Solving Pain to Enhance Living Well, which employs wearable activity tracking technology and nurse consultations for people with chronic low back pain.MethodsThis one-arm longitudinal study recruited 40 adults aged 18-60 years with chronic low back pain. Over 12 weeks, participants watched 10 short video modules, wore activity trackers, and participated in nurse consultations every 2 weeks. At baseline and the 12-week follow-up, they completed study questionnaires, quantitative sensory testing, and blood sample collection.ResultsForty participants were recruited, and their mean age was 29.8. Thirty-two participants completed the survey questionnaire, quantitative sensory testing, Fitbit activity tracker, and bi-weekly nurse consultation, and 25 completed the evaluation of biological markers. The overall satisfaction with the Problem-Solving Pain to Enhance Living Well video modules, nurse consultations, and Fitbit in pain management was rated as excellent. No adverse events were reported. Between the baseline and 12-week follow-up, there was a significant decrease in pain intensity and interference and an increase in the warm detection threshold at the pain site.ConclusionsDespite concerns about the participant burden due to multidimensional assessment and intensive education, the feasibility of the Problem-Solving Pain to Enhance Living Well intervention was favorable. Technology-based self-management interventions can offer personalized strategies by integrating pain phenotypes, genetic markers, and physical activity types affecting pain conditions.Trial registrationThis pilot study was registered with ClinicalTrials.gov [NCT03637998, August 20, 2018]. The first participant was enrolled on September 21, 2018.

Project description:BACKGROUND:Regardless of the disease burden of human papillomavirus (HPV), the vaccine has not been included in the Indonesia National Immunization Program. Since 2017 there was a demonstration program of the HPV vaccination in Yogyakarta Province. This vaccine was given free to female primary school students in the 5th and 6th grades (11-13?years old). This study aimed to assess whether a structured-educational intervention focus on HPV increases the parental awareness, knowledge, and perceptions toward HPV and the vaccine acceptability. METHODS:We conducted a pre-post structured-educational intervention study from July to August 2017 before the implementation of the HPV vaccination demonstration program, in Kulon Progo District, Yogyakarta Province, Indonesia. Parents of female primary school students grades 5th and 6th were selected using a school-based proportional random sampling. A pediatric resident provided a structured-educational intervention, which consists of the burden and risk of HPV disease, as well as the benefit and safety of the vaccine. Parents were required to complete validated self-administered questionnaires before and after the structured-educational intervention. RESULTS:A total of 506 parents participated. Before receiving the structured-educational intervention, parents' awareness of HPV infection and the vaccines were low. Only 49.2% of parents had heard HPV infection, and 48.8% had heard about the vaccine. After the structured-educational intervention, there were significant improvements in parent's awareness, knowledge, and perceptions of HPV infection, cervical cancer, and HPV vaccination (all p <?0.001). HPV vaccine's acceptability increased from 74.3 to 87.4% (p <?0.001). There was a significant correlation between increasing HPV vaccine acceptability with the improvement of awareness, knowledge, and perception toward HPV infection, cervical cancer and HPV vaccination (r?=?0.32 to 0.53, p <?0.001). After the structured-educational intervention, better knowledge and positive perceptions of HPV vaccination were predictive of HPV vaccine's acceptability with OR 1.90 (95%CI:1.40-2.57) and OR 1.31(95%CI,1.05-1.63), respectively. CONCLUSIONS:A structured-educational intervention may improve parental awareness, knowledge, and perceptions toward HPV and the acceptability of the vaccine. Further study, a randomized control trial with longer follow-up are needed to evaluate the long-term and actual effectiveness of improving parents' knowledge, perceptions and HPV vaccine acceptability.
