Observer pain scales are commonly used to assess pain in individuals with impaired cognition. However, nursing staff have highlighted that extremely tight time schedules and increasing workload demands prevent regular use. With the development of a short version of the Pain Assessment in Impaired Cognition (PAIC15), we aimed to reduce implementation barriers in everyday clinical practice. ⋯ Observer pain scales are commonly used to assess pain in individuals with impaired cognition. However, nursing staff have highlighted that extremely tight time schedules and increasing workload demands prevent regular use. To address this, we developed PAIC6, a short version of the Pain Assessment in Impaired Cognition 15 (PAIC15). PAIC6 includes six items and takes 2 min for completion after training, realising a 60%-time reduction compared to the original scale while keeping the psychometric quality high.

Although the behavioral response to pain is complex and involves supraspinal processes, assessment of pain symptoms in animal models still mainly relies on reflex-based nociceptive tests, which do not account for the affective-motivational nor cognitive components of pain. We introduce a double avoidance place preference paradigm, an integrated testing procedure in freely moving rats that relies on the conflict between the avoidance of a dark compartment in which a thermal ramp is activated, and the escape towards an aversive brightly lit compartment. We were able to differentiate the first nociceptive threshold from the temperature of definitive escape from the dark compartment, conveying information on the adaptive behavior of animals. ⋯ In animals exhibiting hyperalgesia following intraplantar complete Freund adjuvant injection, escape thresholds were significantly higher than that of control animals, hinting at a maladaptive affective-motivational response to noxious stimulation. However, in cuff animals, we failed to reveal any hot nociceptive hypersensitivity, but animals exhibited a strong adaptive response to cold simulation upon reexposure. Overall, the proposed paradigm allows for an integrated cortical response leading to a proactive avoidance behavior, while fully complying with ethical standards in animal experimentation.

School refusal is a longstanding difficulty for youth with chronic pain. Yet, research is hindered by lack of adequate measurement tools to assess and describe the complex interpersonal and systems-level factors contributing to school refusal. This study investigates the utility of the School Refusal Evaluation (SCREEN) measure and its psychometric properties in a sample of youth with chronic pain. ⋯ Our results provide evidence that youth with chronic pain experience significant challenges with school functioning and offer some support for the reliability and validity of the SCREEN in a sample of youth with chronic pain, a population for which few appropriate measures of school functioning have been established. The SCREEN measure may aid in assessing school refusal, with good clinical potential to quantify risk and identify modifiable factors.

Observational StudyPain assessment and management of adult patients in the Swedish EMS: a nationwide registry study.
Pain is a frequent reason for contacting the Emergency Medical Services (EMS), and effective pain management constitutes one of its cornerstones. The aims of this study have been: (a) to describe the prevalence of pain intensity ratings in EMS care of patients with pain-related conditions; (b) to describe pain treatment in the EMS setting in terms of drugs administered and the proportion of patients receiving analgesics and (c) to investigate the relationship between patients' self-reported pain intensity and vital signs. ⋯ This 2-year cohort study highlights significant deficiencies in recorded pain assessment and management in the Swedish EMS. Only 22.5% of the patients had their pain assessed with a validated scale, while 27.5% received analgesics, although pain-related conditions were a common reason for contacting the EMS. The findings indicate a lack of systematic pain assessment which puts many patients at risk of insufficient pain relief.

Review Meta AnalysisPrevalence of and recommendation for measuring chronic postsurgical pain in children: an updated systematic review and meta-analysis.
According to the prior 2017 review (Rabbitts et al), approximately 20% of children and adolescents develop chronic postsurgical pain (CPSP; ie, pain persisting >3 months after surgery) after major surgeries, which is associated with adverse functional and psychological consequences. A major barrier was that definitions of CPSP applied were highly variable. Since that prior review was conducted (n=4 studies in meta-analysis), numerous relevant studies have been published warranting an update. ⋯ CRD42022306340.
