Therapeutic communication improves patient comfort during venipuncture in children: a single-blinded intervention study.

The aim of this study was to examine whether therapeutic communication improves children's comfort during venipuncture compared to standard communication. This study was registered in the Dutch trial register (NL8221), December 10, 2019. This single-blinded interventional study was carried out in an outpatient clinic of a tertiary hospital. Inclusion criteria were age between 5 and 18 years, use of topical anesthesia (EMLA) and sufficient understanding of the Dutch language. 105 children were included, 51 assigned to the standard communication group (SC group) and 54 patients to the therapeutic communication group (TC group). The primary outcome measure was self-reported pain based on the Faces Pain Scale Revised (FPS-R). Secondary outcome measures were observed pain (numeric rating scale (NRS)), self-reported/observed anxiety in child and parent (NRS), self-reported satisfaction in child, parent and medical personnel (NRS), and procedural time. No difference was found for self-reported pain. Self-reported and observed anxiety (by parents and medical personnel) was lower in the TC group (p-values ranged from p = 0.005 to p = 0.048). Procedural time was lower in the TC group (p = 0.011). Satisfaction level of medical personnel was higher in the TC group (p = 0.014).   Conclusion: TC during venipuncture did not result in lower self-reported pain. However, secondary outcomes (observed pain, anxiety and procedural time) were significantly improved in the TC group. What is Known: • Medical procedures, especially needle related procedures, cause anxiety and fear in children and adults. • In adults communication techniques based on hypnosis are effective in reducing pain and anxiety during medical procedures. What is New: • Our study found that with a small change in communication technique (called therapeutic communication or TC), the comfort of children during venipuncture improves. • This improved comfort was mainly reflected by reduced anxiety scores and shorter procedural time. This makes TC suitable for the outpatient setting.

Common needs in uncommon conditions: a qualitative study to explore the need for care in pediatric patients with rare diseases.

BACKGROUND: Challenges faced by children diagnosed with a rare disease or complex condition and their family members are often characterized by disease-specific complexities, such as a prolonged diagnostic process, an uncertain prognosis, and the absence of curative treatment. The psychological burden of living with a rare disease or complex condition is often understudied and may present overarching concepts that shape the general experience of having been diagnosed with a rare condition. The present study examines common needs from a comprehensive perspective combining relevant aspects from the rare disease literature in a theoretical perspective from pediatric psychology, such as a family-centred, developmental and interdisciplinary approach. An exploratory study was designed among parents from children with a rare disease or complex condition in an Integrated University Children's Hospital in the Netherlands. Semi-structured interviews were conducted with open-ended questions based around the experience of having a child diagnosed with a rare condition, such as the psychosocial impact on the child and it's development, the impact on the family, and how provided care was experienced. RESULTS: Twelve interviews were analysed with a thematic content analysis to identify common needs. Eight themes followed from the analysis and uncovered the need for (1) family-focused care, (2) coping with uncertainty, (3) empathic communication, (4) practical support, (5) information, (6) psychological support, (7) interdisciplinary care, and (8) social support. CONCLUSIONS: The results from our study provide directions for research and health care to support young patients with a rare disease or complex condition and their families. Moreover, our results demonstrated that there are overarching concepts across different rare diseases that may be optimally supported with interdisciplinary care.

Explaining placebo effects in an online survey study: Does 'Pavlov' ring a bell?

OBJECTIVES: Despite the increasing knowledge about placebo effects and their beneficial impact on treatment outcomes, strategies that explicitly employ these mechanisms remain scarce. To benefit from placebo effects, it is important to gain better understanding in how individuals want to be informed about placebo effects (for example about the underlying mechanisms that steer placebo effects). The main aim of this study was to investigate placebo information strategies in a general population sample by assessing current placebo knowledge, preferences for different placebo explanations (built around well-known mechanisms involved in placebo effects), and attitudes and acceptability towards the use of placebo effects in treatment. DESIGN: Online survey. SETTING: Leiden, The Netherlands. PARTICIPANTS: 444 participants (377 completers), aged 16-78 years. MAIN OUTCOME MEASURES: Current placebo knowledge, placebo explanation preferences, and placebo attitudes and acceptability. RESULTS: Participants scored high on current placebo knowledge (correct answers: M = 81.15%, SD = 12.75). Comparisons of 8 different placebo explanations revealed that participants preferred explanations based on brain mechanisms and positive expectations more than all other explanations (F(7, 368) = 3.618, p = .001). Furthermore, attitudes and acceptability for placebos in treatment varied for the type of the condition (i.e. more acceptant for psychological complaints) and participants indicated that physicians do not always have to be honest while making use of placebo effects for therapeutic benefit. CONCLUSION: Our results brought forth new evidence in placebo information strategies, and indicated that explanations based on brain mechanisms and positive expectations were most preferred. These results can be insightful to construct placebo information strategies for both clinical context and research practices.

Integrating Placebo Effects in General Practice: A Cross-Sectional Survey to Investigate Perspectives From Health Care Professionals in the Netherlands.

Objectives: Placebo effects, beneficial treatment outcomes due to non-active treatment components, play an important role in the overall treatment response. To facilitate these beneficial effects it is important to explore the perspectives of health care professionals (HCPs) on the integration of placebo effects in clinical care. Three themes were investigated: knowledge about placebo effects and factors that contribute to these, frequency of placebo use, and attitudes toward acceptability and transparency of placebo use in treatment. Methods: A cross-sectional survey, according to the Checklist for Reporting Results of Internet E-Surveys guidelines and STrengthening the Reporting of OBservational Studies in Epidemiology (STROBE), was conducted in the Netherlands in 2020. The survey was conducted in two samples: a (nested) short survey in 78 nurses during working shifts (sample 1) and an extended online survey in 47 general HCPs e.g., medical psychologists, oncologists, surgeons (sample 2). Results: Respondents from both samples reported to be somewhat or quite familiar with placebo effects (24.0 and 47.2%, respectively). From the six placebo mechanisms that were presented, mind-body interaction, positive expectations, and brain activity involved in placebo effects were rated as the most influential factors in placebo effects [F(5,119) = 20.921, p < 0.001]. The use of placebo effects was reported in 53.8% (n = 42) of the nurses (e.g., by inducing positive expectations), and 17.4% of the HCPs (n = 8 reported to make use of pure placebos and 30.4% of impure placebos (n = 14). Attitudes toward placebo use in treatment were acceptant, and transparency was highly valued (both up to 51%). Conclusions: The findings from this study address knowledge gaps in placebo effects in practice and provide insights in attitudes toward the integration of placebo effects from HCPs. Altogether, integrating these findings may potentially optimize treatment outcomes.

Pharmacological conditioning for juvenile idiopathic arthritis: a potential solution to reduce methotrexate intolerance.

BACKGROUND: Methotrexate (MTX) therapy has proven to be a successful and safe treatment for Juvenile Idiopathic Arthritis (JIA). Despite the high efficacy rates of MTX, treatment outcomes are often complicated by burdensome gastro-intestinal side effects. Intolerance rates for MTX in children are high (approximately 50%) and thus far no conclusive effective treatment strategies to control for side effects have been found. To address this need, this article proposes an innovative research approach based on pharmacological conditioning, to reduce MTX intolerance. PRESENTATION OF THE HYPOTHESIS: A collaboration between medical psychologists, pediatric rheumatologists, pharmacologists and patient groups was set up to develop an innovative research design that may be implemented to study potential improved control of side effects in JIA, by making use of the psychobiological principles of pharmacological conditioning. In pharmacological conditioning designs, learned positive associations from drug therapies (conditioning effects) are integrated in regular treatment regimens to maximize treatment outcomes. Medication regimens with immunosuppressant drugs that made use of pharmacological conditioning principles have been shown to lead to optimized therapeutic effects with reduced drug dosing, which might ultimately cause a reduction in side effects. TESTING THE HYPOTHESIS: This research design is tailored to serve the needs of the JIA patient group. We developed a research design in collaboration with an interdisciplinary research group consisting of patient representatives, pediatric rheumatologists, pharmacologists, and medical psychologists. IMPLICATIONS OF THE HYPOTHESIS: Based on previous experimental and clinical findings of pharmacological conditioning with immune responses, we propose that the JIA patient group is particularly suited to benefit from a pharmacological conditioning design. Moreover, findings from this study may potentially also be promising for other patient groups that endure long-lasting drug therapies.

The role of placebo effects in immune-related conditions: mechanisms and clinical considerations.

INTRODUCTION: Placebo effects are powerful modulators in clinical outcomes and can either result in treatment benefits or harms, known as placebo and nocebo effects. To harness these outcomes, it is important to focus on the underlying processes that steer these effects, namely by learning through expectations and conditioning. In this review, we focus on the influence of placebo effects on subjective and physiological levels of immune-related conditions (e.g. lymphocyte proliferation, cytokine production or other inflammatory markers). Areas covered: A literature search is conducted in the databases PubMed and PsychInfo by making use of keywords such as 'expectations', 'classical conditioning', 'cytokines', 'immune system', 'learned immunosuppression', and covers studies done in animals, experimental studies in healthy controls as well as studies performed in immune-related patient populations. Expert commentary: We report on the presence of placebo effects in RCTs in immune-related conditions and review findings that demonstrate the ability to learn immune responses in both experimental animal and human placebo studies making use of conditioning paradigms with immunomodulating drug agents. We also discuss results to utilize placebo effects by means of classical conditioning principles in medication regimens for patient populations and elaborate on promising findings of preliminary studies focusing on this topic.
