Boosting open-label placebo effects in acute induced pain in healthy adults (BOLPAP-study): study protocol of a randomized controlled trial

Introduction

Pain is a highly prevalent symptom in the hospital setting, but treatment options remain limited. Harnessing the placebo effect in an ethical manner could provide a new possibility to reduce pain in clinical practice. So called open-label placebos (OLP) have been shown to elicit significant effects in reducing acute pain. But, before implementation, more knowledge concerning the properties of OLPs is needed. This study aims to assess the duration of analgesic effects from OLP and to determine the possibility of boosting such effects.

Methods and analysis

This is the protocol of an ongoing (first patient enrolled in March 2023) single-site randomized trial investigating OLPs in two parts (i.e., substudies). In both parts, pain will be induced in healthy adults using an intradermal electrical stimulation model. Participants in Part 1 will have two study visits: An interventional visit with one OLP injection accompanied by an evidence-based treatment rationale and a control visit with no treatment. For Part 2, participants will be randomized into three groups: (1) A fixed-time "Booster" group including one single repetition of the OLP injection at a fixed time point, (2) an on-demand "Booster" group including one single repetition of the OLP injection on-demand, and (3) a control group who will receive just one OLP injection. Differences in pain ratings over time (using the Numeric Rating Scale) will be analyzed with several two-sample t-tests. The time point for a fixed-time "Booster" in Part 2 will be derived from Part 1 with additional statistical tools such as a broken-stick mixed-effect model.

Discussion

This study aims to further characterize the analgesic effects of OLPs. In doing so, it will provide valuable information needed for later implementation of OLPs in clinical practice, where they could play a role in multimodal analgesic concepts.

Ethics and dissemination

The "Ethikkommission Nordwest- und Zentralschweiz" (BASEC 2023-00296) approved the study protocol. Results of the analysis will be submitted for publication in a peer-reviewed journal.

Clinical Trial Registration

This study is registered at ClinicalTrials.gov (NCT05819476) and is listed in the Swiss National Registry at kofam.ch (SNCTP000005470).

Comparative outcome of different treatment options for fragility fractures of the sacrum

BACKGROUND

Fragility fractures of the sacrum (FFS) have been detected more and more frequently in recent times, and the incidence will continue to increase due to increasing life expectancy. The aim of this study was to compare the clinical outcome of conservative, interventional and surgical treatment of FFS.

METHODS

Retrospectively, 292 patients (276 women, 16 men) with confirmed FFS were followed up over a period of 2 years. The age of the women was Ø 81.2 (58 - 99) and that of the men Ø 78.1 (76 - 85) years. The pain was quantified using a VAS. Fractures were classified in accordance with the Rommens and Hofmann and with the Denis classification using conventional X-rays, CT and MRI. A QCT of the lumbar spine was performed to quantify bone mineral density. Concomitant diseases of every patient were recorded. An interdisciplinary case conference determined the individual treatment concept considering the age, type of fracture, pain level and comorbidities with classification into conservative, interventional (any type of sacroplasty) or surgical treatment. Over the course pain and independence were measured, complications and patient satisfaction were documented. A vitamin D determination was done, and existing comorbidities were included.

RESULTS

Patients with a pain level of ≤5 benefited from the conservative therapy measures, with pain levels > 5 significantly delaying the development of mobility. After sacroplasty, the pain reduced significantly, which caused a rapid improvement in mobility without any significant difference being found between vertebro- (VSP), balloon (BSP), radiofrequency (RFS) and cement sacroplasty (CSP). In terms of pain reduction and mobilization, the surgical treated patients benefited from osteosynthesis, although more complex fracture types with lumbopelvic stabilization took longer. Overall, there were no deaths during the hospital stay. Mortality after 12 months was 21.7% for the conservative, 8.4% for the interventional and 13.6% for the surgical therapy group; the differences are significant. For patients in the conservative therapy group who were difficult to mobilize due to pain, the mortality increased to 24.3%. Over 24 months, patients achieved the best independence after sacroplasty. At 12 and 24 months, subjective satisfaction with the therapies was best after sacroplasty, followed by osteosynthesis and conservative measures. All patients had a pronounced vitamin D deficiency and manifest osteoporosis. Cardiovascular pathologies were the main concomitant diseases.

CONCLUSIONS

Patients with FFS with a low level of pain benefit from conservative therapy measures, whereby complications and mortality increase significantly in the case of persistent immobilizing pain. Patients with an unacceptable level of pain resulting from non-dislocated fractures benefit significantly from sacroplasty. Patients with unstable and displaced fractures (Rommens and Hofmann type III and IV) should be operated on promptly. Different techniques are available for sacroplasty and osteosynthesis, which lead to an improvement of independence and a reduction in mortality.

[Sacral fragility fractures: risk factors and outcomes after cement sacroplasty]

BACKGROUND

The objective of the present study on patients with fragility fractures of the sacrum (FFS) was to assess existing risk factors and clinical outcomes after cement sacroplasty (CSP).

PATIENTS AND METHODS

68 patients (64 women, 4 men) with previous FFS were followed up retrospectively. CT and MRI images were used to classify fractures according to Denis et al. and Rommens and Hofmann. Bone mineral content was determined by QCT in all patients. Concomitant diseases as well as central and peripheral fractures were recorded, considering the patient's medical history and X‑ray images. Vitamin D levels were also determined. If conservative therapy was unsuccessful, CSP was performed. The results were documented on the basis of pain development, physical independence, patient satisfaction, complication rate and mortality.

RESULTS

The age of the women in the study was Ø 83.2 (72-99) and that of the men Ø 77.8 (76-85) years. 42.4% had a Denis type 1, 4.2% a Denis type 2, 0% a Denis type 3, 43.3% a Denis type 1-2 and 10.1% a Denis type 1-2-3 fracture zone. FFP type II a to II c fractures were found in 88.2%, FFP type III c in 7.4% and FFP type IV b in 4.4%. Bilateral FFS were found in 68.8%. The average bone mineral content (BMC) was 35.4 (2-74) mg/ml, and the average vitamin D value was 8.8 (0-28) nmol/l. Other osteoporosis-associated fractures were found in around 50% of the patients. After CSP, patients showed a rapid and significant (p < 0.001) reduction in pain and sustained clinical improvement.

CONCLUSION

FFS fracture risk factors were found to be female gender, advanced age, existing osteoporosis and severe vitamin‑D deficiency. Patients with non-displaced FFS who could not be mobilised due to pain experienced sustained benefit from CSP.

Organisation und Durchführung der Schmerztherapie in deutschen Notaufnahmen – eine Onlineumfrage

Einleitung

Obwohl Schmerzen der häufigste Grund für eine Vorstellung in der Notaufnahme sind, ist ihre Erfassung und Therapie sehr heterogen organisiert und wird vielfach von Patienten als unzureichend beschrieben. Eine spezielle Leitlinie existiert bislang nicht und so wird beispielsweise die Delegation an die Notfallpflege nach Standard Operating Procedure (SOP) sehr unterschiedlich gehandhabt.

Methode

Mithilfe einer Umfrage erfolgte eine Ist-Analyse zur Organisation und Durchführung der akuten Schmerztherapie in deutschen Notaufnahmen. 18 Fragen wurden onlinebasiert erstellt und über das Notaufnahmeverzeichnis der DGINA e. V. (Deutsche Gesellschaft für interdisziplinäre Notfall- und Akutmedizin) und DIVI e. V. (Deutsche Interdisziplinäre Vereinigung für Intensiv- und Notfallmedizin) an die Leiter von 951 deutschen Notaufnahmen verschickt.

Ergebnis

Es konnten 166 vollständige Fragebögen ausgewertet werden. Die Erfassung der Schmerzen erfolgt bei 77,7 % der Notaufnahmen innerhalb der ersten 10 min nach Erstkontakt, meist mit der numerischen Rating-Skala (46,4 %). Obwohl 17,7 % nicht dauerhaft ärztlich besetzt sind, dürfen in insgesamt 32,5 % der Notaufnahmen Pflegekräfte keine eigenständige Schmerztherapie durchführen. Eine spezielle SOP gab es nur in 44,8 % der befragten Notaufnahmen. Die am häufigsten verwendeten Analgetika sind Piritramid und Morphin sowie Metamizol und Ibuprofen.

Schlussfolgerung

Eine entsprechende nationale Leitlinie könnte Handlungssicherheit geben und als Grundlage für angepasste, örtliche SOP helfen, Verzögerungen bei der akuten Schmerztherapie zu vermeiden.

[Analgesia for trauma patients in emergency medicine]

Adequate analgesia is one of the most important measures of emergency care in addition to treatment of vital function disorders and, if indicated, should be promptly undertaken; however, a large proportion of emergency patients receive no or only inadequate pain therapy. The numeric rating scale (NRS) is recommended for pain assessment but is not applicable to every group of patients; therefore, vital signs and body language should be included in the assessment. Pain therapy should reduce the NPRS to <5 points. Ketamine and fentanyl, which have an especially rapid onset of action, and also morphine are suitable for analgesia in spontaneously breathing patients. Basic prerequisites for safe and effective analgesia by healthcare professionals are the use of adequate monitoring, the provision of well-defined emergency equipment, and the mastery of emergency procedures. In a structured competence system, paramedics and nursing personnel can perform safe and effective analgesia.

Effectiveness of the Manchester Triage System on time to treatment in the emergency department: a systematic review

OBJECTIVE

The objective of this review was to synthesize the best available evidence on the effectiveness of the Manchester Triage System (MTS) on time to treatment (TtT) for patients who visit the emergency department (ED).

INTRODUCTION

The objectives of the MTS are to define a safe wait time for medical attention. Triage systems, such as the MTS, use criteria to ensure patient safety by determining appropriate wait times for each individual who visits the ED. The TtT is the time interval between arrival at the ED to initiation of therapeutic interventions. A short TtT is important in different clinical situations and may reduce infections and mortality. The MTS may have an impact on the TtT.

INCLUSION CRITERIA

This review considered studies that included any patients visiting the ED with any complaints or medical diagnoses who were triaged using the MTS by nurses or doctors, and the TtT was measured. This review considered randomized controlled trials, as well as quasi-experimental, before-and-after, case-control and analytical cross-sectional studies. Studies published after 1994 in English, Spanish, Portuguese, French and German were considered for inclusion.

METHOD

This systematic review was conducted in accordance with JBI methodology. The search strategy aimed to find both published and unpublished studies in MEDLINE, CINAHL, Lilacs, Web of Science, Embase, Scopus, Cochrane Central Register of Controlled Trials, Google Scholar, Banco de Teses - CAPES, and Digital Dissertations. The results of this search were assessed by one reviewer who excluded duplicate results. Titles and abstracts were screened by two independent reviewers for assessment against the inclusion criteria. The full texts of potentially eligible papers were retrieved and independently assessed by two reviewers using a standardized critical appraisal instrument from JBI. Data were extracted from studies included in the review and were presented using a narrative form. Tables were used to summarize the characteristics and findings of the studies.

RESULTS

The review included two before-and-after studies, with a total of 2265 participants. One study was of moderate quality, and the other was of high quality. One study included only patients with acute ischemic stroke, while the other included patients with any complaint. Both studies were performed with consecutive samples. The median TtT was 10 minutes before implementing the MTS and 12 minutes after implementing the MTS in the study that included patients with any complaints. In the study including patients with acute ischemic stroke, the median TtT decreased by 15 minutes after implementing the MTS (from 75 to 60 minutes). Because of the heterogeneity in the characteristics of the populations of the two studies, the results could not be pooled.

CONCLUSIONS

The MTS reduced the median TtT for patients triaged at the highest priority levels (orange and yellow), but it did not decrease the median TtT in all patients. The existing evidence base regarding the effectiveness of the MTS comes from two studies with methodological limitations that could not be pooled. The evidence indicates the MTS may confer benefit to some patients who visit the ED by reducing TtT, but not for all patients. Further research is needed before firm conclusions can be made.

A multicenter randomized control trial evaluating professional practice assessment of patient pain management after simulation training course: Study protocol

Aims

Pain is underestimated and insufficiently treated in Emergency Departments (ED). The primary objective of this multicenter, prospective, observational, and interventional study is to analyze the clinical impact of a simulation-based training for Emergency Nurses on pain assessment and management. Secondary objectives are to measure instructed staff's satisfaction with the simulation training and to evaluate the progress of participants as well as studying the clinical impact of this course: level of correlation between accuracy of analgesia and level of pain, assessment of patient and caregiver satisfaction.

Design

this study will be undertaken in EDs at two university hospitals (Paris, France: Bichat and Beaujon) with randomly selected experimental and control groups.

Methods

During the first phase, inventories in the EDs of current professional practice will be realized. Then, the control group will have theoretical classes and the experimental group will have both the theoretical class and simulation courses for all the nurses (with simulated patients in trauma pain scenarios). Post course assessment will be established of triage nurses' and other nurses’ practice changes concerning trauma pain management in EDs. Moreover, this study will include an assessment of the impact on patient and caregiver satisfaction. All patients over 18 years old who are admitted to the ED for a non-vital trauma are included. Exclusion criteria are patients who are admitted by an EMS ambulance.

Clinical implication

this study seeks to demonstrate that the implementation of a theoretical course combined with a simulation session will improve pain management in EDs by Emergency Nurses.

BACKGROUND

Suitable analgesic drugs and techniques are needed for the acute care of the approximately 18 200-18 400 seriously injured patients in Germany each year.

METHODS

This systematic review and meta-analysis of analgesia in trauma patients was carried out on the basis of randomized, controlled trials and observational studies. A systematic search of the literature over the 10-year period ending in February 2016 was carried out in the PubMed, Google Scholar, and Springer Link Library databases. Some of the considered trials and studies were included in a meta-analysis. Mean differences (MD) of pain reduction or pain outcome as measured on the Numeric Rating Scale were taken as a summarizing measure of treatment efficacy.

RESULTS

Out of 685 studies, 41 studies were considered and 10 studies were included in the meta-analysis. Among the drugs and drug combinations studied, none was clearly superior to another with respect to pain relief. Neither fentanyl versus morphine (MD -0.10 with a 95% confidence interval of [-0.58; 0.39], p = 0.70) nor ketamine versus morphine (MD -1.27 [-3.71; 1.16], p = 0.31), or the combination of ketamine and morphine versus morphine alone (MD -1.23 [-2.29; -0.18], p = 0.02) showed clear superiority regarding analgesia.

CONCLUSION

Ketamine, fentanyl, and morphine are suitable for analgesia in spontaneously breathing trauma patients. Fentanyl and ketamine have a rapid onset of action and a strong analgesic effect. Our quantitative meta-analysis revealed no evidence for the superiority of any of the three substances over the others. Suitable monitoring equipment, and expertise in emergency procedures are prerequisites for safe and effective analgesia by healthcare professionals..
