Background: For more than a decade, studies have supported the efficacy and safety of placebos without deception-so-called open-label placebos (OLPs)-to harness placebo effects in primary care while aligning with key ethical principles. Since treatment acceptance, feasibility, and successful implementation of novel interventions into clinical practice depend on patients' attitudes, patients' perspectives, perceived obstacles, and ideas on OLP use in clinical practice have yet to be elucidated. Therefore, patient and public involvement is increasingly demanded in research and its implementation into clinical practice.

Introduction: In countries with access to the electronic health record (EHR), both patients and healthcare professionals have reported finding errors in the EHR, so-called EHRrors. These can range from simple typos to more serious cases of missing or incorrect health information. Despite their potential detrimental effect, the evidence on EHRrors has not been systematically analysed.

Background: In a growing number of countries, patients are offered access to their full online clinical records, including the narrative reports written by clinicians (the latter, referred to as "open notes"). Even in countries with mature patient online record access, access to psychotherapy notes is not mandatory. To date, no research has explored the views of psychotherapy trainees about open notes.

Introduction: Chronic postsurgical pain (CPSP) is defined as pain that persists after a surgical procedure and has a significant impact on quality of life. Previous studies show the importance of psychological factors in CPSP, yet the majority of studies focused solely on negative emotions. This longitudinal observational study aims to broaden this knowledge base by examining the role of emotional state, emotion variability, emotion regulation and emotion differentiation on the child and the parent level for the development CPSP, and to describe pain and emotion-related trajectories following surgery.

Three meta-analyses have demonstrated the clinical potential of open-label placebos (OLPs). However, there is a need to synthesize the existing evidence through more complex analyses that would make it possible to answer questions beyond mere efficacy. Such analyses would serve to improve the understanding of why and under what circumstances OLPs work (e.

Objective: Chronic pain is a common complaint in children and adolescents, placing an enormous burden on individuals, their families, and the healthcare system. New innovative approaches for the treatment of pediatric chronic pain (PCP) are clearly warranted, as drop-out rates in intervention studies are high and it can be difficult to engage patients with PCP in therapy. Here, animal-assisted interventions (AAIs) might be promising, since there is preliminary evidence for the approach in adults with chronic pain, and AAIs are generally known to foster the therapeutic motivation of patients.

Research indicates that patients consider empathy as a key factor contributing to the quality-of-care. However, ambiguities in the definition of this multidimensional construct complicate definite conclusions to-date. Addressing the challenges in the literature, and using a hypothetical physician-patient interaction which explored patient-perceived differences between expressions of affective empathy, cognitive empathy, compassion and no empathy, this study aimed to test whether lay participants' evaluations of the quality-of-care depend on the type of empathic physician behavior, and on the physician's gender.

Placebos have been shown to be beneficial for various conditions even if administered with full transparency. Hence, so-called open-label placebos (OLPs) offer a new way to harness placebo effects ethically. To take this concept one step further, this study aimed at evaluating placebo effects without the use of a physical placebo, i.

  • Chronic pain in children and adolescents is common but often overlooked, necessitating a deeper understanding of pediatricians' perspectives on the condition.
  • The study involved a survey of Swiss pediatricians to investigate their beliefs about the causes of chronic musculoskeletal pain and how they communicate these to patients and families.
  • Findings showed that while pediatricians recognized psychological factors as significant, they predominantly conveyed biological explanations when discussing pain with patients, highlighting a need to better integrate the biopsychosocial framework in treatment approaches.

A growing body of cross-cultural survey research shows high percentages of clinicians report using placebos in clinical settings. One motivation for clinicians using placebos is to help patients by capitalising on the placebo effect's reported health benefits. This is not surprising, given that placebo studies are burgeoning, with increasing calls by researchers to ethically harness placebo effects among patients.
