Validation of an acute pain-behavior scale for older persons with inability to communicate verbally: Algoplus

End-of-life Comfort Evaluation, is Clinic Enough? A Retrospective Cohort Study of Combined Comfort Evaluation with Analgesia/Nociception Index and Clinic in non-Communicative Patients

Background: Comfort evaluation is one of the major challenges in the palliative care setting, particularly when it comes to non-communicative patients. For this specific population, validated tools for comfort evaluation are scarce and healthcare professionals have to rely on their clinical sense and experience. Objectives: To provide arguments for the use of Analgesia/Nociception Index (ANI) monitoring in order to improve clinical comfort evaluation. Methods: We conducted a retrospective cohort study of non-communicative patients at the end of their lives whose comfort was evaluated clinically and with ANI. We focused on the coherence or discordance of clinical and ANI evaluations and on pharmacological interventions driven by them. Results: 58 evaluations from 33 patients were analyzed. Clinical and demographic characteristics were highly variable. Simultaneous clinical and ANI evaluations were concordant in 45 measurements (77.58%), leading mostly to no treatment modification when indicating comfort and to increasing anxiolytic or pain-relief treatments when indicating discomfort. Thirteen (22.41%) evaluations were discordant, leading mostly to treatment incrementation. Conclusion: We suggest that the ANI monitor is a reliable tool in the palliative setting and may help provide patients with the best symptom relief and the most appropriate therapeutics.

Palliative sedation - revised recommendations

Palliative sedation is defined as the monitored use of medications intended to induce a state of decreased or absent awareness (unconsciousness) to relieve the burden of otherwise intractable suffering in a manner ethically acceptable to the patient, their family, and healthcare providers. In Switzerland, the prevalence of continuous deep sedation until death increased from 4.7% in 2001 to 17.5% of all deceased in 2013, depending on the research method used and on regional variations. Yet, these numbers may be overestimated due to a lack of understanding of the term "continuous deep sedation" by for example respondents of the questionnaire-based study. Inadequately trained and inexperienced healthcare professionals may incorrectly or inappropriately perform palliative sedation due to uncertainties regarding its definitions and practice. Therefore, the expert members of the Bigorio group and the authors of this manuscript believe that national recommendations should be published and made available to healthcare professionals to provide practical, terminological, and ethical guidance. The Bigorio group is the working group of the Swiss Palliative Care Society whose task is to publish clinical recommendations at a national level in Switzerland. These recommendations aim to provide guidance on the most critical questions and issues related to palliative sedation. The Swiss Society of Palliative Care (palliative.ch) mandated a writing board comprising four clinical experts (three physicians and one ethicist) and two national academic experts to revise the 2005 Bigorio guidelines. A first draft was created based on a narrative literature review, which was internally reviewed by five academic institutions (Lausanne, Geneva, Bern, Zürich, and Basel) and the heads of all working groups of the Swiss Society of Palliative Care before finalising the guidelines. The following themes are discussed regarding palliative sedation: (a) definitions and clinical aspects, (b) the decision-making process, (c) communication with patients and families, (d) patient monitoring, (e) pharmacological approaches, and (f) ethical and controversial issues. Palliative sedation must be practised with clinical and ethical accuracy and competence to avoid harm and ethically questionable use. Specialist palliative care teams should be consulted before initiating palliative sedation to avoid overlooking other potential treatment options for the patient's symptoms and suffering.

Perioperative analgesia in the elderly

The administration of analgesic drugs in elderly patients should take into account age-related physiological changes, loss of efficiency of homeostatic mechanisms, and pharmacological interactions with chronic therapies. Underestimation of pain in patients with impaired cognition is often linked to difficulties in pain assessment. In the preoperative phase, it is essential to assess the physical status, cognitive reserve, and previous chronic pain conditions to plan effective analgesia. Furthermore, an accurate pharmacological history of the patient must be collected to establish any possible interaction with the whole perioperative analgesic plan. The use of analgesic drugs with different mechanisms of action for pain relief in the intraoperative phase is a crucial step to achieve adequate postoperative pain control in older adults. The combined multimodal and opioid-sparing strategy is strongly recommended to reduce side effects. The use of various adjuvants is also preferable. Moreover, the implementation of non-pharmacological approaches may lead to faster recovery. High-quality postoperative analgesia in older patients can be achieved only with a collaborative interdisciplinary team. The aim of this review is to highlight the perioperative pain management strategies in the elderly with a special focus on intraoperative pharmacological interventions.

The influence of Alzheimer's disease stigma on pain assessment in older persons

INTRODUCTION

Pain of nursing homes residents with Alzheimer's disease remains under detected compared to their cognitively intact counterparts. Communication difficulties may partly explain this poor quality of care but the influence of stigmatization on pain assessment has never been explored.

RESEARCH QUESTION

The objective of this research was to analyze whether a diagnosis label of Alzheimer's disease or the stage of the disease may bias pain assessment scores and empathic reactions of health care staff in nursing homes.

METHODS

Two studies were conducted based on a similar experimental between-subjects design with a video showing an older adult woman experiencing undefined pain. Different labels and vignettes were manipulated to characterize the subject of the video. In the first study, 84 certified nursing assistants were asked to watch the video and then to assess the pain intensity and their empathic reaction. Participants were randomized in two conditions that varied the disease label (Alzheimer's disease vs no diagnosis). In the second study, 67 certified nursing assistants were enrolled who did not participate in the first study. They watched the same video as in the first study and assessed the pain intensity and their empathic reaction. They were randomized in two conditions that varied the stage of the Alzheimer's disease (mild stage vs severe stage).

RESULTS

Alzheimer's disease label had no influence on assessment scores. In contrast, the stage of the disease had a significant effect on the health care staff assessments with severe stage associated with lower pain intensity scores and empathic reactions.

CONCLUSION

These results confirm that the Alzheimer's disease stigma is a real phenomenon that tends to be mainly elicited by the symptoms of the acute phase of the disease. These findings are crucial to better understand the stigma related to Alzheimer's disease and to enhance the pain management of this frail population.

Psychometric properties of pain measurements for people living with dementia: a COSMIN systematic review

PURPOSE

Detecting pain in older people with dementia is challenging. Consequentially, pain is often under-reported and under-treated. There remains uncertainty over what measures should be promoted for use to assess pain in this population. The purpose of this paper is to answer this question.

METHODS

A search of clinical trials registered on the ClinicalTrial.gov and ISRCTN registries was performed to identify outcome measures used to assess pain in people with dementia. Following this, a systematic review of published and unpublished databases was performed to 01 November 2021 to identify papers assessing the psychometric properties of these identified measures. Each paper and measure was assessed against the COSMIN checklist. A best evidence synthesis analysis was performed to assess the level of evidence for each measure.

RESULTS

From 188 clinical trials, nine outcome measures were identified. These included: Abbey Pain Scale, ALGOPLUS, DOLOPLUS-2, Facial Action Coding System, MOBID-2, self-reported pain through the NRS or VAS/thermometer or Philadelphia Geriatric Pain Intensity Scale, PACSLAC/PACSLAC-2, Pain Assessment in Advanced Dementia (PAINAD), and Checklist for non-verbal pain behavior (CNPI). From these, 51 papers (5924 people with dementia) were identified assessing the psychometric properties of these measures. From these, there was strong- and moderate-level evidence to support the use of the facial action coding system, PACSLAC and PACSLAC-II, CNPI, DOLOPLUS-2, ALGOPLUS, MOBID, and MOBID-2 tools for the assessment of pain with people living with dementia.

CONCLUSION

Whilst these reflect measurement tools used in research, further consideration on how these reflect clinical practice should be considered.

Artificial intelligence to evaluate postoperative pain based on facial expression recognition

BACKGROUND

Pain intensity evaluation by self-report is difficult and biased in non-communicating people, which may contribute to inappropriate pain management. The use of artificial intelligence (AI) to evaluate pain intensity based on automated facial expression analysis has not been evaluated in clinical conditions.

METHODS

We trained and externally validated a deep-learning system (ResNet-18 convolutional neural network) to identify and classify 2810 facial expressions of 1189 patients, captured before and after surgery, according to their self-reported pain intensity using numeric rating scale (NRS, 0-10). AI performances were evaluated by accuracy (concordance between AI prediction and patient-reported pain intensity), sensitivity and specificity to diagnose pain ≥4/10 and ≥7/10. We then confronted AI performances with those of 33 nurses to evaluate pain intensity from facial expression in the same situation.

RESULTS

In the external testing set (120 face images), the deep learning system was able to predict exactly the pain intensity among the 11 possible scores (0-10) in 53% of the cases with a mean error of 2.4 points. Its sensitivities to detect pain ≥4/10 and ≥7/10 were 89.7% and 77.5%, respectively. Nurses estimated the right NRS pain intensity with a mean accuracy of 14.9% and identified pain ≥4/10 and ≥7/10 with sensitivities of 44.9% and 17.0%.

CONCLUSIONS

Subject to further improvement of AI performances through further training, these results suggest that AI using facial expression analysis could be used to assist physicians to evaluate pain and detect severe pain, especially in people not able to report appropriately their pain by themselves.

SIGNIFICANCE

These original findings represent a major step in the development of a fully automated, rapid, standardized and objective method based on facial expression analysis to measure pain and detect severe pain.

Reliability and Safety of Bedside Blind Bone Biopsy Performed by a Diabetologist for the Diagnosis and Treatment of Diabetic Foot Osteomyelitis

OBJECTIVE

Bone biopsy (BB) performed by a surgeon or an interventional radiologist is recommended for suspicion of osteomyelitis underlying diabetic foot ulcer (DFU). To facilitate its practice, we developed a procedure allowing bedside blind bone biopsy (B4) by a diabetologist.

RESEARCH DESIGN AND METHODS

We conducted a three-step observational study consisting of a feasibility and safety phase (phase 1) to assess the success and side effects of B4, a validity phase (phase 2) to compare DFU outcomes between positive (B4+) and negative (B4-) bone cultures, and a performance phase (phase 3) to compare B4 with the conventional surgical or radiological procedure basic bone biopsy (B3). Primary end points were the presence of bone tissue (phase 1) and complete DFU healing with exclusive medical treatment at 12 months (phases 2 and 3).

RESULTS

In phase 1, 37 consecutive patients with clinical and/or radiological suspicion of DFU osteomyelitis underwent B4. Bone tissue was collected in all patients with few side effects. In phase 2, a B4+ bone culture was found in 40 of 79 (50.6%) participants. Among B4+ patients, complete wound healing after treatment was 57.5%. No statistical difference was observed with patients with B4- bone culture not treated with antibiotics (71.8%, P = 0.18). In phase 3, the proportion of patients with positive BB was lower in B4 (40 of 79, 50.6%) than in B3 (34 of 44, 77.3%, P < 0.01). However, complete healing was similar (64.6% vs. 54.6%, P = 0.28). No difference in rate of culture contamination was observed.

CONCLUSIONS

B4 is a simple, safe, and efficient procedure for the diagnosis of DFU osteomyelitis with a similar proportion of healing to conventional BB.

Management of preoperative pain in elderly patients with moderate to severe cognitive deficits and hip fracture: a retrospective, monocentric study in an orthogeriatric unit

Background

Patients with cognitive deficits are 3 times more likely to suffer a hip fracture than geriatric patients of the same age group without cognitive deficits. The persistence of perioperative pain following hip fracture is a risk factor for the occurrence of delirium, poor functional prognosis, and the development of secondary chronic pain. Patients with cognitive deficits receive 20 to 60% less analgesics than those without cognitive deficits. Our retrospective descriptive monocentric study was performed in an orthogeriatric unit on a cohort of elderly patients hospitalized for hip fracture. The aim of the study was to compare the quantity of strong opioids delivered in a morphine sulfate equivalent daily during the preoperative period after a hip fracture between cognitively intact patients and those with cognitive deficits.

Results

Our total population of 69 patients had a median age of 90 years old, and 46% of these patients had moderate or severe cognitive deficits. During the preoperative period, the same quantity of strong opioids was administered to both groups of patients (13.1 mg/d versus 10.8 mg/d (p = 0.38)). Patients with moderate to severe cognitive deficits more often experienced delirium during their hospitalization (p < 0.01) and received more psychotropic drugs in the first 3 postoperative days (p = 0.025).

Conclusions

We reported that with standardized pain management in an orthogeriatric unit, patients aged 75 years and older received the same daily average quantity of strong opioids during the preoperative period regardless of the presence of cognitive deficits.

Postadychute-AG, Detection, and Prevention of the Risk of Falling Among Elderly People in Nursing Homes: Protocol of a Multicentre and Prospective Intervention Study

Introduction: While falls among the elderly is a public health issue, because of the social, medical, and economic burden they represent, the tools to predict falls are limited. Posturography has been developed to distinguish fallers from non-fallers, however, there is too little data to show how predictions change as older adults' physical abilities improve. The Postadychute-AG clinical trial aims to evaluate the evolution of posturographic parameters in relation to the improvement of balance through adapted physical activity (APA) programs. Methods: In this prospective, multicentre clinical trial, institutionalized seniors over 65 years of age will be followed for a period of 6 months through computer-assisted posturography and automatic gait analysis. During the entire duration of the follow-up, they will benefit from a monthly measurement of their postural and locomotion capacities through a recording of their static balance and gait thanks to a software developed for this purpose. The data gathered will be correlated with the daily record of falls in the institution. Static and dynamic balance measurements aim to extract biomechanical markers and compare them with functional assessments of motor skills (Berg Balance Scale and Mini Motor Test), expecting their superiority in predicting the number of falls. Participants will be followed for 3 months without APA and 3 months with APA in homogeneous group exercises. An analysis of variance will evaluate the variability of monthly measures of balance in order to record the minimum clinically detectable change (MDC) as participants improve their physical condition through APA. Discussion: Previous studies have stated the MDC through repeated measurements of balance but, to our knowledge, none appear to have implemented monthly measurements of balance and gait. Combined with a reliable measure of the number of falls per person, motor capacities and other precipitating factors, this study aims to provide biomechanical markers predictive of fall risk with their sensitivity to improvement in clinical status over the medium term. This trial could provide the basis for posturographic and gait variable values for these elderly people and provide a solution to distinguish those most at risk to be implemented in current practice in nursing homes. Trial Registration: ID-RCB 2017-A02545-48. Protocol Version: Version 4.2 dated January 8, 2020.

Interrater Variability in Pain Assessment of Long-term Care Residents with Dementia

PURPOSE

People with dementia are at great risk of their pain being undetected. In long-term care facilities, certified nursing assistants are on the front-line to detect whether a resident with dementia is experiencing pain, but research on certified nursing assistants' abilities to accurately assess pain are scarce. This study aims to examine certified nursing assistants' pain assessment skills using a simulated standardized video context.

DESIGN

A cross-sectional study was conducted.

METHODS

Fifty certified nursing assistants and 40 individuals with no professional experience in the field of care (controls) watched the same video of an older adult woman with dementia experiencing pain. Afterwards, they completed visual analog scales (pain intensity, affective distress), an observational pain assessment scale (Algoplus), and a set of questionnaires.

RESULTS

In both groups, pain intensity assessment and empathic reaction scores showed important interrater variability. Moreover, certified nursing assistants and controls did not differ in detecting the presence of pain or assessing its intensity. But certified nursing assistants displayed lower empathic reactions and dispositions. Certified nursing assistants pain assessment scores decreased with experience and expertise.

CONCLUSIONS

The practice of pain assessment is challenging for certified nursing assistants in long-term care facilities. Their professional status does not prevent inter-personal inconsistency and tends to lower their empathic dispositions. Personal determinants may interfere with their assessment behaviors and must be considered to enhance pain management for residents with dementia.

How do patients with Alzheimer's disease imagine their pain?

INTRODUCTION

Pain is underdiagnosed and undertreated in patients with Alzheimer's disease (AD). Pain management is of major importance in this population to limit behavioural and functional consequences. Our study aimed to assess the capacity of AD patients to represent pain using a questionnaire exploring daily painful situations and to determine the most appropriate pain scale assessment.

METHODS

Twenty-eight patients with mild AD, 21 with moderate AD and 28 matched controls underwent the Situation Pain Questionnaire (SP-Q) and assessed imaginary pain with four pain scales. Two scores were compared between the three groups: the P(A) discrimination score and the response bias β score. P(A) reflects the degree of discrimination between high-pain and low-pain events, whereas the β score means the degree to which situations are considered as painful.

RESULTS

Our results showed that AD patients hardly discriminated the high- from low-pain events. Compared to controls, the mean P(A) score was significantly lower for Mild AD (p < 0.03) and Moderate AD (p < 0.004). In addition, the β score indicated that the response bias is higher for AD patients (p < 0.01) in that they overestimated the level of pain.

CONCLUSION

The present results suggest that patients with Mild and Moderate AD are able to recognize and assess an imagined painful situation even though their pain tolerance is lower than that of controls. The pain scales used should be chosen according to the cognitive, sensorial and personal profiles of the patients.

SIGNIFICANCE

The present research is significant because it examines how patients with Alzheimer's disease understand and assess painful situations. Cognitive impairments can modify this ability. Pain is a sensory and subjective experience and to define its feeling can help us in our clinical practice.

Management of Ambulatory Anesthesia in Older Adults

The number of older patients is increasing globally. Combined with the growing number of ambulatory surgeries, many older patients will undergo ambulatory surgery in the future. The ambulatory setting offers many advantages: early mobilization, higher patient satisfaction, lower costs, and a low incidence of several complications such as infections and thromboembolic events. Moreover, cognitive recovery seems to be enhanced compared with in-hospital surgery, and both frail patients and patients with dementia can benefit from ambulatory surgery. This review provides suggestions for managing perioperative anesthesia for older patients in the ambulatory setting. Not all older patients are eligible for ambulatory surgery, and clinicians must be aware of risk factors for complications, especially frailty. Most anesthesia techniques and agents can be used in the ambulatory setting, but short-acting agents are preferred to ensure fast recovery. Both regional and general anesthesia are useful, but clinicians must be familiar with the physiological changes and specific implications in the older population. The older patients are more sensitive to anesthetic agents, meaning that a lower dose is needed to obtain the desired effect. However, they exhibit huge variation in pharmacodynamics and pharmacokinetics. Prolonged onset time may lead to overdosing and extended recovery. After surgery, effective pain management with opioid minimization is essential to ensure rapid recovery.

Validation of the Critical Care Pain Observational Tool in Palliative Care

PURPOSE

Pain assessment at the end of life remains a problem for patients who are unable to self-report their pain when transitioning across care settings. This study therefore tested the internal consistency and discriminant, concurrent, and convergent validity of the Critical-Care Pain Observational Tool (French version) when used with end-of-life patients in a palliative care setting.

DESIGN

This was a descriptive correlational study that used a repeated-measures within-subjects prospective design.

METHODS

The pain of 13 patients was assessed when at rest and during turning.

RESULTS

The internal consistency reliability coefficient alphas were .64 at rest and .70 during turning. Discriminant validity was shown by a decrease in the total Critical-Care Pain Observation Tool score. Concurrent validity was demonstrated by the association between the patients' self-report of pain and the Critical-Care Pain Observation Tool score at rest (0.65, p < .016) and during turning (0.77, p = .002). Finally, the convergent validity between the Critical-Care Pain Observation Tool score and the Algoplus scale score was demonstrated with a Spearman's correlation coefficient of 0.76 at rest and 0.84 during turning.

CONCLUSIONS

The results suggest that the Critical-Care Pain Observation Tool can be used with end-of-life patients in French-speaking countries.

Pain in dementia

The ageing revolution is changing the composition of our society with more people becoming very old with higher risks for developing both pain and dementia. Pain is normally signaled by verbal communication, which becomes more and more deteriorated in people with dementia. Thus, these individuals unnecessarily suffer from manageable but unrecognized pain. Pain assessment in patients with dementia is a challenging endeavor, with scientific advancements quickly developing. Pain assessment tools and protocols (mainly observational scales) have been incorporated into national and international guidelines of pain assessment in aged individuals. To effectively assess pain, interdisciplinary collaboration (nurses, physicians, psychologists, computer scientists, and engineers) is essential. Pain management in this vulnerable population is also preferably done in an interdisciplinary setting. Nonpharmacological management programs have been predominantly tested in younger populations without dementia. However, many of them are relatively safe, have proven their efficacy, and therefore deserve a first place in pain management programs. Paracetamol is a relatively safe and effective first-choice analgesic. There are many safety issues regarding nonsteroidal anti-inflammatory drugs, opioids, and adjuvant analgesics in dementia patients. It is therefore recommended to monitor both pain and potential side effects regularly. More research is necessary to provide better guidance for pain management in dementia.

Management of acute pain in dementia: a feasibility study of a robot-assisted intervention

Background: The management of pain is particularly challenging in patients with moderate to severe dementia owing to the loss of communication ability or underlying causes such as behavioral symptoms. It is often associated with health care professionals’ frustration and feeling of helplessness. The present study determined a framework and examined the feasibility of an innovative intervention using the PARO^® robot for the management of acute pain in dementia.

Method: A mixed-methods research design combining qualitative (five focus groups) and quantitative (questionnaire survey) approaches was used to define the intervention framework. We recruited 57 health care professionals from various medical and paramedical specialties (eg, nursing auxiliaries, nurses, physicians, psychologists) and with expertise in gerontology. The feasibility of the intervention was subsequently assessed with 12 patients suffering from dementia in painful situations to validate the procedure.

Results: Four main issues have been addressed: 1) the identification of a core group of painful situations associated with care (washing, dressing/change, transfer/mobilization), currently considered as inefficiently managed; 2) the selection of an appropriate assessment methodology including criteria and tools for pain evaluation; 3) the definition of health professionals' training needs and organizational requirements for their implementation; and 4) the perceived usefulness of a robot-assisted intervention for the management of pain in dementia in daily practice. The feasibility study showed that the predefined intervention framework was applicable and acceptable for the majority of professionals and patients.

Conclusion: A consistent and feasible intervention framework for the management of painful situations associated with care in dementia using the PARO robot was defined. Understanding of professionals’ needs, opinions and perceived obstacles regarding the intervention was a useful step in the preparation of the forthcoming clinical trial.

Assessing cancer pain-the first step toward improving patients' quality of life

PURPOSE

Numerous studies on cancer patients have shown that cancer pain still remains underestimated, poorly assessed, and under-treated. Pain relief should be considered as early as possible within personalized care and as an integral part of quality healthcare in many countries. Nevertheless, personalized care is still insufficiently taken into consideration, partly due to improper or incomplete assessment of cancer pain. The objective of this article is to propose a practical approach to this complex assessment, as the first step to improving patients' quality of life.

METHODS

Critical reflection based on literature analysis and clinical practice.

RESULTS

Assessment of cancer pain means evaluating the pain intensity over time, the dimensions of pain (sensory-discriminative, cognitive, emotional, and behavioral), the pathophysiological nature of pain (neuropathic, nociceptive, and nociplastic), the etiology, and the patient's perception (diffuse, localized, global). Cancer patients may have simple or multiple forms of pain (mixed, overlapped, combined, and associated). Furthermore, with the use of new specific therapies, the symptomatology of pain is also changing, and certain cancers are becoming chronic. Thus, cancer pain is an archetype of multimorphic pain, and its dynamic assessments (regular and repeated) require a multimodal and targeted approach in order to offer personalized pain management. Multimodal pain treatment must be adapted to the elements that disrupt cancer pain, to the patient's cancer and to the specific treatments.

CONCLUSIONS

The dynamic assessments of pain demand the simplest, and the most complete possible procedure, to avoid feasibility problems or self-/hetero-assessment excesses that might lead to less precise and less reliable results. Multimodal and interdisciplinary approaches are being developed, making it possible to optimize cancer pain management.

Effect of Exercise on Behavioral Symptoms and Pain in Patients With Dementia Living in Nursing Homes

OBJECTIVES

Examine the effects of a 6-month exercise intervention on neuropsychiatric symptoms, pain, and medication consumption in older people with dementia (PWD) living in nursing homes (NH).

METHODS

Ninety-one older PWD living in NH performed a 6-month structured exercise intervention (n = 44) or a social activity intervention (n = 47). Neuropsychiatric symptoms were measured by the neuropsychiatric inventory (NPI), pain was assessed using the Algoplus scale, and dementia-related drug prescriptions were obtained for all participants.

RESULTS

Between-group analysis found a nonsignificant difference that could be of clinical relevance: a 4-point difference in the NPI and 1.3-point difference in the reduction of the number of medications favoring exercisers. No significant differences were found for pain, and a trend was found for an increase in medication consumption in the social group.

CONCLUSION

Exercise effects did not differ from social intervention effects on neuropsychiatric symptoms, pain, and medication consumption in older PWD living in NH.

Modalités d’analgésie-sédation procédurale utilisées en traumatologie extrahospitalière par les médecins urgentistes de France métropolitaine

Introduction : L’analgésie-sédation procédurale (ASP) consiste à administrer des agents sédatifs permettant aux patients de tolérer des procédures désagréables. L’ASP a fait l’objet de recommandations formalisées d’experts de la Société française de médecine d’urgence (SFMU) depuis 2010. L’objectif était d’évaluer l’impact de ces recommandations sur les pratiques des smuristes en France concernant la réalisation d’une ASP.

Méthodes : Enquête téléphonique réalisée de janvier à juillet 2016. Nous avons joint un médecin de permanence le jour de l’appel dans chaque service mobile d’urgence et de réanimation (Smur) métropolitain. Il devait répondre à un questionnaire focalisé sur une situation clinique pour laquelle une ASP était indiquée : fracture fémorale déplacée.

Résultats : Chaque Smur métropolitain a été joint (n = 384), et 309 médecins ont répondu au questionnaire (80 %). Quarante-deux combinaisons thérapeutiques différentes ont été proposées, et 308 médecins (99 %) administraient soit un sédatif, soit un opioïde, soit les deux. La morphine était le principal antalgique utilisé (n = 232 ; 75 %), les posologies et les modalités correspondant aux dernières recommandations. La kétamine était le sédatif le plus utilisé (n = 163 ; 53 %), mais les posologies étaient inférieures à celles recommandées La douleur des patients communicants était évaluée avec une échelle adaptée. La douleur des patients non communicants, adultes ou enfants, n’était pas évaluée avec une échelle adaptée. Un tiers des Smur avait un protocole d’ASP, et 27 % des médecins disaient connaître les recommandations. Au total, il y avait une grande hétérogénéité des modalités de réalisation de l’ASP, avec notamment des difficultés de maniement des sédatifs, des recommandations peu connues et un faible taux de protocoles dans les Smur.

Clinical experience changes the combination and the weighting of audio-visual sources of information

OBJECTIVE

Although audio and visual information constitute relevant channels to communicate pain, it remains unclear to what extent observers combine and weight these sources of information when estimating others' pain. The present study aimed to examine this issue through the theoretical framework of the Information Integration Theory. The combination and weighting processes were addressed in view of familiarity with others' pain.

METHOD

Twenty-six participants familiar with pain (novice podiatry clinicians) and thirty non-specialists were asked to estimate the level of pain associated with different displayed locomotor behaviors. Audio and visual information (i.e., sound and gait kinematics) were combined across different intensities and implemented in animated human stick figures performing a walking task (from normal to pathological gaits).

RESULTS

The novice clinicians and non-specialists relied significantly on gaits and sounds to estimate others' pain intensity. The combination of the two types of information obeyed an averaging rule for the majority of the novice clinicians and an additive rule for the non-specialists. The novice clinicians leaned more on gaits in the absence of limping, whereas they depended more on sounds in the presence of limping. The non-specialists relied more on gaits than on sounds. Overall, the novice clinicians attributed greater pain levels than the non-specialists did.

CONCLUSION

Depending on a person's clinical experience, the combination of audio and visual pain-related behavior can qualitatively change the processes related to the assessment of others' pain. Non-verbal pain-related behaviors as well as the clinical implications are discussed in view of the assessment of others' pain.

Subcutaneous administration of paracetamol-Good local tolerability in palliative care patients: An observational study

BACKGROUND

The subcutaneous route is widely used in both palliative care and geriatrics. Numerous compounds are administered by this route, including paracetamol. However, there is no recommendation on which to base this latter practice and, in the absence of published evidence, nothing is known regarding its local tolerability in palliative care patients.

AIM

The main objective of this study was to assess the local tolerability of paracetamol when administered subcutaneously for analgesic or antipyretic purposes in patients hospitalized in the palliative care unit. The secondary objective was to identify the factors favoring the occurrence of local adverse events.

DESIGN

This is a prospective multicenter observational study (NCT02884609).

PARTICIPANTS

Study conducted in 160 patients hospitalized in the palliative care units of three hospitals in metropolitan France from 2014 to 2017.

RESULTS

Of the 160 patients, 44 (28%) presented at least one non-serious local adverse event (edema in 29, erythema in 5, pain in 15, hematoma in 2, pruritus in 1, and local heat in 2). No serious adverse events were observed. Factors associated with the occurrence of local adverse events were younger age, administration in the arm and thorax, and a high number of daily administrations.

CONCLUSION

This first ever study carried out on this subject reveals that subcutaneous administration of paracetamol in palliative care patients was well tolerated locally.

Algoplus® Scale in Older Patients with Dementia: A Reliable Real-World Pain Assessment Tool

Pain is still a neglected clinical issue in elderly people with dementia and/or communicative disorders, with an unacceptable higher rate of under diagnosis and under treatment. Cognitive deficit and emotional and psychological disturbances entangle pain symptoms, affecting patient self-report. So far, observational pain tools do not have fully adequate clinimetric properties and quality requirements for easy-to-use daily rating. Older patients with dementia represent a clinical challenge. The assessment of pain is important for improving clinical outcomes, such as functional status, frailty trajectories, comorbidity, and quality of life. The PAINAID scale appears to be the most accurate pain tool in people with dementia along with the Algoplus® scale, a recently developed tool to rapidly assess acute pain in hospitals settings. The present study aimed to assess the clinimetric properties of the Algoplus®, as compared to PAINAID, for detecting acute pain in a real-world cohort of hospitalized older patients with dementia.

Determinants of inappropriate acute pain management in old people unable to communicate verbally in the emergency department

Objectives

Poor pain management is relevant among individuals unable to communicate verbally (UCV). Analgesia may be due to three determinants: patients' status, physician's characteristics and pain etiology. Our aim is to investigate the association between prescription of ED pain treatment and these determinants.

Materials and Methods

An observational prospective study including UCV patients was conducted. Severity of pain was evaluated by ALGOPLUS Scale and a score P ≥ 2 out of 5 on the pain scale was retained as the threshold for the presence of acute pain in elderly UCV patients.

Results

Our data showed that only 31,9% of UCV patients received a pharmacological treatment. The presence of the caregiver would influence the rate of therapy administration [OR 6,19 (95% CI 2,6–14,75)]. The presence of leg pain [OR 0,32 (95% CI 0,12–0,86)] and head pain [OR 0,29 (95% CI 0,10–0,84)] were less likely associated to receive analgesia. Pain related to trauma [OR 4.82 (95% CI 1.17 to 19.78)] and youngest physicians [OR 1.08 (95% CI 1.001 to 1.18)] were variables associated with the administration of drugs opiates.

Discussion

Older UCV patients presenting to the ED with pain are at high risk of inadequate analgesia. Providers should always suspect presence of pain and an increasing need for behavioural pain evaluation is necessary for a complete assessment.

Conclusions

Presence of a caregiver influences a more appropriate pain management in these patients. Staff training on pain management could result in better assessment, treatment, and interaction with caregivers.

Towards improved decision support in the assessment and management of pain for people with dementia in hospital: a systematic meta-review and observational study

Background

Pain and dementia are common in older people, and impaired cognitive abilities make it difficult for them to communicate their pain. Pain, if poorly managed, impairs health and well-being. Accurate pain assessment in this vulnerable group is challenging for hospital staff, but essential for appropriate management. Robust methods for identifying, assessing and managing pain are needed.

Aims and objectives

Two studies were undertaken to inform the development of a decision support tool to aid hospital staff in the recognition, assessment and management of pain. The first was a meta-review of systematic reviews of observational pain assessment instruments with three objectives: (1) to identify the tools available to assess pain in adults with dementia; (2) to identify in which settings they were used and with what patient populations; and (3) to assess their reliability, validity and clinical utility. The second was a multisite observational study in hospitals with four objectives: (1) to identify information currently used by clinicians when detecting and managing pain in patients with dementia; (2) to explore existing processes for detecting and managing pain in these patients; (3) to identify the role (actual/potential) of carers in this process; and (4) to explore the organisational context in which health professionals operate. Findings also informed development of health economics data collection forms to evaluate the implementation of a new decision support intervention in hospitals.

Methods

For the meta-review of systematic reviews, 12 databases were searched. Reviews of observational pain assessment instruments that provided psychometric data were included. Papers were quality assessed and data combined using narrative synthesis. The observational study used an ethnographic approach in 11 wards in four UK hospitals. This included non-participant observation of 31 patients, audits of patient records, semistructured interviews with 52 staff and four carers, informal conversations with staff and carers and analysis of ward documents and policies. Thematic analysis of the data was undertaken by the project team.

Results

Data from eight systematic reviews including 28 tools were included in the meta-review. Most tools showed moderate to good reliability, but information about validity, feasibility and clinical utility was scarce. The observational study showed complex ward cultures and routines, with variations in time spent with patients, communication patterns and management practices. Carer involvement was rare. No pain decision support tools were observed in practice. Information about pain was elicited in different ways, at different times, by different health-care staff and recorded in separate documents. Individual staff made sense of patients’ pain by creating their own ‘overall picture’ from available information.

Limitations

Grey literature and non-English-language papers were excluded from the meta-review. Sample sizes in the observational study were smaller than planned owing to poor documentation of patients’ dementia diagnoses, gatekeeping by staff and difficulties in gaining consent/assent. Many patients had no or geographically distant carers, or a spouse who was too unwell and/or reluctant to participate.

Conclusions

No single observational pain scale was clearly superior to any other. The traditional linear concept of pain being assessed, treated and reassessed by single individuals did not ‘fit’ with clinical reality. A new approach enabling effective communication among patients, carers and staff, centralised recording of pain-related information, and an extended range of pain management interventions is proposed [Pain And Dementia Decision Support (PADDS)]. This was not tested with users, but a follow-on study aims to codesign PADDS with carers and clinicians, then introduce education on staff/patient/carer communications and use of PADDS within a structured implementation plan. PADDS will need to be tested in differing ward contexts.

Sedation by Propofol for Painful Care Procedures at the End of Life: A Pilot Study. PROPOPAL 1

BACKGROUND

At the end of life, patients may feel refractory pain during care procedures although they receive appropriate analgesia. They can benefit from a short-term sedation. Propofol is used for procedural sedation in emergency or reanimation departments. It may be adapted in a palliative care unit.

OBJECTIVE

The main objective was to verify whether propofol could allow us to administer care without causing major pain to patients with refractory pain at the end of life.

DESIGN

We conducted an open, prospective, and uncontrolled pilot study.

SETTING/SUBJECTS

The study was conducted in one palliative care center in France. The subjects were patients with an estimated prognosis less than three months who experienced pain during care procedures, although they receive appropriate analgesia.

RESULTS

Ten patients were included. Care was delivered with no major pain for 9 patients out of 10. The average duration of induction to reach deep sedation was 4 minutes (2-8) and of care procedures was 13 minutes (7-32). On average, the patient woke up 11.5 minutes after we stopped injecting propofol (7-18). Only one patient experienced a significant adverse effect caused by propofol, but it did not have any harmful consequence except the interruption of care procedures.

CONCLUSION

Transitory sedation using propofol for terminally ill patients hospitalized in a palliative care unit can offer optimal comfort during painful care procedures without significant complications. Patients woke up quickly. Further studies will have to be conducted to verify these initial results and make sure there are no major drawbacks.

An Algorithm for Neuropathic Pain Management in Older People

Neuropathic pain frequently affects older people, who generally also have several comorbidities. Elderly patients are often poly-medicated, which increases the risk of drug-drug interactions. These patients, especially those with cognitive problems, may also have restricted communication skills, making pain evaluation difficult and pain treatment challenging. Clinicians and other healthcare providers need a decisional algorithm to optimize the recognition and management of neuropathic pain. We present a decisional algorithm developed by a multidisciplinary group of experts, which focuses on pain assessment and therapeutic options for the management of neuropathic pain, particularly in the elderly. The algorithm involves four main steps: (1) detection, (2) evaluation, (3) treatment, and (4) re-evaluation. The detection of neuropathic pain is an essential step in ensuring successful management. The extent of the impact of the neuropathic pain is then assessed, generally with self-report scales, except in patients with communication difficulties who can be assessed using behavioral scales. The management of neuropathic pain frequently requires combination treatments, and recommended treatments should be prescribed with caution in these elderly patients, taking into consideration their comorbidities and potential drug-drug interactions and adverse events. This algorithm can be used in the management of neuropathic pain in the elderly to ensure timely and adequate treatment by a multidisciplinary team.

Identifying and Managing Pain in People with Alzheimer's Disease and Other Types of Dementia: A Systematic Review

BACKGROUND AND OBJECTIVE

Pain in patients with Alzheimer's disease is a complex issue; these patients suffer from the common causes of acute and chronic pain, and some also have neuropathic or nociceptive pain. Whatever the mechanism of pain in these patients, their pain will require careful assessment and management, to insure the correct type and level of analgesia is given. The objective of this systematic review was the identification of studies that have investigated the efficacy of different analgesics on pain intensity or pain-related behavior during nursing home stay and at the end of life.

METHODS

A search using pain, pain treatment, and dementia MESH terms and keywords was conducted (October 15, 2015) in MEDLINE, EMBASE, PsychINFO, CINAHL, and Cochrane libraries.

RESULTS

Our search yielded 3138 unique hits, published between 1990 and October 2015. We read titles and abstracts, identified 124 papers for full-text evaluation, and included 12 papers to reflect and synthesize the following questions: (1) Which pain assessment tools for people with dementia are responsive to change in pain intensity scores? (2) Which analgesics are efficacy-tested by controlled trials including people with dementia living in nursing homes, including at the end of life? (3) Which outcome measures have been used to identify pain, pain behavior, and/or treatment efficacy in people with dementia?

CONCLUSION

Despite increased use of analgesics, pain is still prevalent in people with dementia. Validated pain tools are available but not implemented and not fully tested on responsiveness to treatment. Official guidelines for pain assessment and treatment addressing people with dementia living in a nursing home are lacking. The efficacy of analgesic drug use on pain or neuropsychiatric behavior related to dementia has been hardly investigated.

Pain Assessment with Cognitively Impaired Older People in the Acute Hospital Setting

Research reveals that older people continue to experience much suffering from acute and chronic pain conditions.People with cognitive impairment receive less analgesia than their cognitively intact peers.Postoperative pain assessment with older people in the acute hospital setting remains a challenge.Context and culture have a significant impact of pain assessment practices.Due to a paucity of research exploring how pain assessment and management practices with cognitively impaired older people may be realised in the acute hospital setting, there is a need for further research to be conducted.

Diagnostic Accuracy of Respiratory Distress Observation Scales as Surrogates of Dyspnea Self-report in Intensive Care Unit Patients

Background:

Dyspnea, like pain, can cause major suffering in intensive care unit (ICU) patients. Its evaluation relies on self-report; hence, the risk of being overlooked when verbal communication is impaired. Observation scales incorporating respiratory and behavioral signs (respiratory distress observation scales [RDOS]) can provide surrogates of dyspnea self-report in similar clinical contexts (palliative care).

Methods:

The authors prospectively studied (single center, 16-bed ICU, large university hospital) 220 communicating ICU patients (derivation cohort, 120 patients; separate validation cohort, 100 patients). Dyspnea was assessed by dyspnea visual analog scale (D-VAS) and RDOS calculated from its eight components (heart rate, respiratory rate, nonpurposeful movements, neck muscle use during inspiration, abdominal paradox, end-expiratory grunting, nasal flaring, and facial expression of fear). An iterative principal component analysis and partial least square regression process aimed at identifying an optimized D-VAS correlate (intensive care RDOS [IC-RDOS]).

Results:

In the derivation cohort, RDOS significantly correlated with D-VAS (r = 0.43; 95% CI, 0.29 to 0.58). A five-item IC-RDOS (heart rate, neck muscle use during inspiration, abdominal paradox, facial expression of fear, and supplemental oxygen) significantly better correlated with D-VAS (r = 0.61; 95% CI, 0.50 to 0.72). The median area under the receiver operating curve of IC-RDOS to predict D-VAS was 0.83 (interquartile range, 0.81 to 0.84). An IC-RDOS of 2.4 predicted D-VAS of 4 or greater with equal sensitivity and specificity (72%); an IC-RDOS of 6.3 predicted D-VAS of 4 or greater with 100% specificity. Similar results were found in the validation cohort.

Conclusions:

Combinations of observable signs correlate with dyspnea in communicating ICU patients. Future studies in noncommunicating patients will be needed to determine the responsiveness to therapeutic interventions and clinical usefulness.

Effective pain management in patients with dementia: benefits beyond pain?

This current opinion aims to provide a literature overview of the associations between pain and neuropsychiatric symptoms and the efficacy of pain management for both pain and neuropsychiatric symptoms in patients with dementia. In addition, international guidelines and recommendations for pain management have been collated, and important developing research areas are highlighted. Pain is, in general, under-recognized and undertreated in people with dementia and may therefore trigger or exacerbate neuropsychiatric symptoms. While there is an abundance of pain assessment instruments intended for people with dementia, few have been adequately tested for their feasibility, reliability and validity. In patients with dementia, vocalizations, facial expressions and body movements may be the only valid expressions of pain. Further, pain has been related to the neuropsychiatric symptoms of agitation, aggression, mood syndrome and sleep problems. Unfortunately, health personnel may misinterpret these symptoms as neuropsychiatric symptoms of dementia. A differential assessment of dementia, its presenting neuropsychiatric symptoms and the potential presence of pain is crucial to provide the correct treatment. To achieve this, use of pain assessment tools that are responsive to change and are validated for use in patients with dementia is a prerequisite. To date, there have been few studies, with inconsistent findings on the association between pain and neuropsychiatric symptoms. To ensure a better differential assessment of pain and neuropsychiatric symptoms, and consequently more accurate treatment for patients with dementia, studies with adequate statistical power and high-quality study designs, including randomized controlled trials, are needed.

Pain assessment for people with dementia: a systematic review of systematic reviews of pain assessment tools

BACKGROUND

There is evidence of under-detection and poor management of pain in patients with dementia, in both long-term and acute care. Accurate assessment of pain in people with dementia is challenging and pain assessment tools have received considerable attention over the years, with an increasing number of tools made available. Systematic reviews on the evidence of their validity and utility mostly compare different sets of tools. This review of systematic reviews analyses and summarises evidence concerning the psychometric properties and clinical utility of pain assessment tools in adults with dementia or cognitive impairment.

METHODS

We searched for systematic reviews of pain assessment tools providing evidence of reliability, validity and clinical utility. Two reviewers independently assessed each review and extracted data from them, with a third reviewer mediating when consensus was not reached. Analysis of the data was carried out collaboratively. The reviews were synthesised using a narrative synthesis approach.

RESULTS

We retrieved 441 potentially eligible reviews, 23 met the criteria for inclusion and 8 provided data for extraction. Each review evaluated between 8 and 13 tools, in aggregate providing evidence on a total of 28 tools. The quality of the reviews varied and the reporting often lacked sufficient methodological detail for quality assessment. The 28 tools appear to have been studied in a variety of settings and with varied types of patients. The reviews identified several methodological limitations across the original studies. The lack of a 'gold standard' significantly hinders the evaluation of tools' validity. Most importantly, the samples were small providing limited evidence for use of any of the tools across settings or populations.

CONCLUSIONS

There are a considerable number of pain assessment tools available for use with the elderly cognitive impaired population. However there is limited evidence about their reliability, validity and clinical utility. On the basis of this review no one tool can be recommended given the existing evidence.

The MOBID-2 pain scale: reliability and responsiveness to pain in patients with dementia

BACKGROUND

Mobilization-Observation-Behavior-Intensity-Dementia-2 (MOBID-2) pain scale is a staff-administered pain tool for patients with dementia. This study explores MOBID-2's test-retest reliability, measurement error and responsiveness to change.

METHODS

Analyses are based upon data from a cluster randomized trial including 352 patients with advanced dementia from 18 Norwegian nursing homes. Test-retest reliability between baseline and week 2 (n = 163), and weeks 2 and 4 (n = 159) was examined in patients not expected to change (controls), using intraclass correlation coefficient (ICC2.1 ), standard error of measurement (SEM) and smallest detectable change (SDC). Responsiveness was examined by testing six priori-formulated hypotheses about the association between change scores on MOBID-2 and other outcome measures.

RESULTS

ICCs of the total MOBID-2 scores were 0.81 (0-2 weeks) and 0.85 (2-4 weeks). SEM and SDC were 1.9 and 3.1 (0-2 weeks) and 1.4 and 2.3 (2-4 weeks), respectively. Five out of six hypotheses were confirmed: MOBID-2 discriminated (p < 0.001) between change in patients with and without a stepwise protocol for treatment of pain (SPTP). Moderate association (r = 0.35) was demonstrated with Cohen-Mansfield Agitation Inventory, and no association with Mini-Mental State Examination, Functional Assessment Staging and Activity of Daily Living. Expected associations between change scores of MOBID-2 and Neuropsychiatric Inventory - Nursing Home version were not confirmed.

CONCLUSION

The SEM and SDC in connection with the MOBID-2 pain scale indicate that the instrument is responsive to a decrease in pain after a SPTP. Satisfactory test-retest reliability across test periods was demonstrated. Change scores ≥ 3 on total and subscales are clinically relevant and are beyond measurement error.

Guidelines (short version) of the French Oto-Rhino-Laryngology--Head and Neck Surgery Society (SFORL) for the management of post-tonsillectomy pain in adults

OBJECTIVES

The present clinical practice guidelines cover the entire field of management of post-tonsillectomy pain. Given the French and European regulatory restrictions on the use of codeine, an update appears necessary to clarify the management of post-tonsillectomy pain in adults.

METHOD

A work group approached the issue of pain management, following the chronological pathway from initial consultation to postoperative period. As exhaustive a study of the literature as possible assessed the pain impact of the various surgical techniques and the efficacy of the various analgesia schedules.

RESULTS

Guidelines on the management of post-tonsillectomy pain in adults were drawn up and graded, based on the levels of evidence of selected articles and on work group consensus. The guidelines stress the importance of patient information and seek to harmonize practice, reduce the risk of postoperative complications and above all improve control of post-tonsillectomy pain in adults.

Acute postoperative pain management in the older patient

Acute pain management in the older adult is both challenging and rewarding. This review addresses the difficulty with assessment of pain in the older adult, variations in the pain experience of older adults, physiological differences between the young and old, changes in pharmacokinetics and pharmacodynamics with age, and useful pharmacological treatments for acute pain in older adults. It then presents a few representative cases of pain management in older adults. The goal of this review is to provide relevant information that can be used to manage acute postoperative pain in the older adult.
