Use of actigraphy for monitoring agitation and rest-activity cycles in patients with acute traumatic brain injury in the ICU.

BACKGROUND: In traumatic brain injury patients (TBI) admitted to the intensive care unit (ICU), agitation can lead to accidental removal of catheters, devices as well as self-extubation and falls. Actigraphy could be a potential tool to continuously monitor agitation. The objectives of this study were to assess the feasibility of monitoring agitation with actigraphs and to compare activity levels in agitated and non-agitated critically ill TBI patients. METHODS: Actigraphs were placed on patients' wrists; 24-hour monitoring was continued until ICU discharge or limitation of therapeutic efforts. Feasibility was assessed by actigraphy recording duration and missing activity count per day. RESULTS: Data from 25 patients were analyzed. The mean number of completed day of actigraphy per patient was 6.5 ± 5.1. The mean missing activity count was 20.3 minutes (±81.7) per day. The mean level of activity measured by raw actigraphy counts per minute over 24 hours was higher in participants with agitation than without agitation. CONCLUSIONS: This study supports the feasibility of actigraphy use in TBI patients in the ICU. In the acute phase of TBI, agitated patients have higher levels of activity, confirming the potential of actigraphy to monitor agitation.

Cognitive and Motor Function Effects of Antipsychotics in Traumatic Brain Injury: A Systematic Review of Pre-Clinical Studies.

Traumatic brain injury (TBI) survivors often suffer from agitated behaviors and will most likely receive pharmacological treatments. Choosing an optimal and safe treatment that will not interfere with neurological recovery remains controversial. By interfering with dopaminergic circuits, antipsychotics may impede processes important to cognitive recovery. Despite their frequent use, there have been no large randomized controlled studies of antipsychotics for the management of agitated behaviors during the acute TBI recovery period. We conducted a systematic review and meta-analysis of pre-clinical studies evaluating the effects of antipsychotics post-TBI on both cognitive and motor recovery. MEDLINE and Embase databases were searched up to August 2, 2023. Pre-clinical studies evaluating the effects of antipsychotics on cognitive and motor functions post-TBI were considered. Risk of bias was evaluated with the Systematic Review Centre for Laboratory Animal Experimentation (SYRCLE) tool. We identified 15 studies including a total of 1188 rodents, mostly conducted in male Sprague-Dawley rats using cortical impact injury. The analysis revealed no consistent effect of haloperidol on motor functions, but risperidone was associated with a significant impairment in motor function on day 5 post-injury (7.05 sec; 95% confidence interval [CI]: 1.47, 12.62; I2 = 92%). Other atypical antipsychotics did not result in impaired motor function. When evaluating cognitive function, haloperidol- (23.00 sec; 95% CI: 17.42-28.59; I2 = 7%) and risperidone-treated rats (24.27 sec; 95% CI: 16.18-32.36; I2 = 0%) were consistently impaired when compared to controls. In studies evaluating atypical antipsychotics, no impairments were observed. Clinicians should avoid the regular use of haloperidol and risperidone, and future human studies should be conducted with atypical antipsychotics.

Physicians' beliefs and perceived importance of traumatic brain injury-associated agitation in critically ill patients: a survey of Canadian intensivists.

PURPOSE: Agitation is a common behavioural problem following traumatic brain injury (TBI). Intensive care unit (ICU) physicians' perspectives regarding TBI-associated agitation are unknown. Our objective was to describe physicians' beliefs and perceived importance of TBI-associated agitation in critically ill patients. METHODS: Following current standard guidance, we built an electronic, self-administrated, 42-item survey, pretested it for reliability and validity, and distributed it to 219 physicians working in 18 ICU level-1 trauma centres in Canada. We report the results using descriptive statistics. RESULTS: The overall response rate was 93/219 (42%), and 76/93 (82%) respondents completed the full survey. Most respondents were men with ten or more years of experience. Respondents believed that pre-existing dementia (90%) and regular recreational drug use (86%) are risk factors for agitation. Concerning management, 91% believed that the use of physical restraints could worsen agitation, 90% believed that having family at the bedside reduces agitation, and 72% believed that alpha-2 adrenergic agonists are efficacious for managing TBI agitation. Variability was observed in beliefs on epidemiology, sex, gender, age, socioeconomic status, and other pharmacologic options. Respondents considered TBI agitation frequent enough to justify the implementation of management protocols (87%), perceived the current level of clinical evidence on TBI agitation management to be insufficient (84%), and expressed concerns about acute and long-term detrimental outcomes and burden to patients, health care professionals, and relatives (85%). CONCLUSION: Traumatic brain injury-associated agitation in critically ill patients was perceived as an important issue for most ICU physicians. Physicians agreed on multiple approaches to manage TBI-associated agitation although agreement on epidemiology and risk factors was variable.

RéSUMé: OBJECTIF: L'agitation est un problème de comportement courant à la suite d'un traumatisme crânien (TC). Le point de vue des médecins des unités de soins intensifs (USI) sur l'agitation associée aux traumatismes crâniens est inconnu. Notre objectif était de décrire les croyances et l'importance perçue par les médecins de l'agitation associée aux traumatismes crâniens chez les patient·es gravement malades. MéTHODE: Conformément aux lignes directrices standard actuelles, nous avons élaboré un sondage électronique auto-administré de 42 questions, l'avons testé au préalable pour en vérifier la fiabilité et la validité, et l'avons distribué à 219 médecins travaillant dans les USI de 18 centres de traumatologie de niveau 1 au Canada. Les résultats sont présentés à l'aide de statistiques descriptives. RéSULTATS: Le taux de réponse global a été de 93 sur 219 (42 %) et 76 sur 93 (82 %) personnes interrogées ont répondu à l'ensemble du sondage. La plupart des répondant·es étaient des hommes comptant dix ans ou plus d'expérience. Les répondant·es sont d'avis que la démence préexistante (90 %) et la consommation régulière de drogues à des fins récréatives (86 %) sont des facteurs de risque d'agitation. En ce qui concerne la prise en charge, 91 % des répondant·es estiment que l'utilisation de contentions physiques peut aggraver l'agitation, 90 % croient que le fait d'avoir de la famille au chevet du patient ou de la patiente réduit l'agitation et 72 % pensent que les agonistes alpha-2 adrénergiques sont efficaces pour gérer l'agitation causée par les traumatismes crâniens. Une variabilité a été observée dans les croyances concernant l'épidémiologie, le sexe, le genre, l'âge, le statut socio-économique et d'autres options pharmacologiques. Les répondant·es considéraient que l'agitation liée aux traumatismes crâniens était suffisamment fréquente pour justifier la mise en œuvre de protocoles de prise en charge (87 %), estimaient que le niveau actuel de données probantes cliniques sur la prise en charge de l'agitation causée par un traumatisme crânien était insuffisant (84 %), et se sont dit·es préoccupé·es par les conséquences préjudiciables aiguës et à long terme et par le fardeau pour les patient·es, les professionnel·les de la santé et les proches (85 %). CONCLUSION: L'agitation associée à un traumatisme crânien chez les patient·es gravement malades était perçue comme un problème important pour la plupart des médecins des soins intensifs. Les médecins s'entendaient sur plusieurs approches pour gérer l'agitation associée aux traumatismes crâniens, bien que l'accord sur l'épidémiologie et les facteurs de risque était variable.

EXperienceS and aTtitudes towards Agitated behaviours in Traumatic brain injury in the Intensive Care unit patients (EXSTATIC): a protocol for an interprofessional mixed-method study.

INTRODUCTION: Agitation and violent behaviours are common conditions developed by patients with acute traumatic brain injury (TBI) in intensive care units (ICUs). Healthcare professionals caring for these patients have various tools to manage these behaviours, but lack of a formal protocol to assess and manage them makes caring for these patients a challenge. Moreover, safety may often be compromised for both ICU professionals and patients encountering such situations. The EXperienceS and aTtitudes towards Agitated behaviours in Traumatic brain injury in the Intensive Care unit patients (EXSTATIC) study aims to explore the experiences and attitudes of ICU nurses and other ICU healthcare professionals on the management of agitated behaviours in patients with acute TBI. METHODS AND ANALYSIS: EXSTATIC is a multicenter mixed methods convergent study exploring experiences and attitudes of ICU healthcare professionals caring of agitated patients with TBI. The study includes three qualitative methods (observation, semistructured interviews and focus groups) and one quantitative method (retrospective cohort). The integration of the different methods will be done using sequential steps of the research and by the integration of results for each step. Qualitative data will be evaluated following a thematic analysis derived from a grounded theory approach. Quantitative data will be analysed using descriptive statistics. Qualitative and quantitative results will be combined in a convergent interactive interpretative design. Gender and race perspective will be integrated in collection, analysis and interpretation of data. ETHICS AND DISSEMINATION: This study has been approved by the Centre intégré universitaire de santé et de services sociaux du nord de l'île de Montréal (CIUSSS-NÎM) Research Ethics Board. The findings will be disseminated locally with ICU staff and health managers, international peer-reviewed journals, a PhD dissertation, and national and international conferences. The knowledge derived from this study is key in the development of clinical protocols to manage agitation and related behaviours in patients with TBI and designing further interventional studies targeting this specific problematic. TRIAL REGISTRATION NUMBER: NCT04741399.

Safety of dexmedetomidine for the control of agitation in critically ill traumatic brain injury patients: a descriptive study.

BACKGROUND: Behavioural disturbances such as agitation are common following traumatic brain injury and can interfere with treatments, cause self-harm and delay rehabilitation. As there is a lack of evidence on the optimal approach to manage agitation in recovering TBI patients, various pharmacological agents are used including antipsychotics, anticonvulsants and sedative agents. Among sedatives, the safety and efficacy of dexmedetomidine to control agitation in traumatic brain injury patients is not well documented. OBJECTIVE: To describe the safety, use and efficacy of dexmedetomidine for the management of agitation following traumatic brain injury in the intensive care unit. METHODS: Medical records of all patients admitted to the intensive care unit of the Hôpital Sacré-Coeur de Montréal for a traumatic brain injury who received dexmedetomidine for agitation between 1 January 2017 and 31 December 2017 were reviewed. Patients who received dexmedetomidine for indications other than agitation were excluded. Data on dexmedetomidine prescription practices and safety were extracted. Frequency of agitation and concomitant psychoactive medication use was explored over a period starting two days prior to the initiation of dexmedetomidine to six days after or discontinuation, whichever came first. RESULTS: We identified 41 patients in whom dexmedetomidine was initiated. Dexmedetomidine was started on median ICU day 3 (25th -75th percentiles: 2-7) and had a median treatment duration of 3 days (25th -75th percentiles: 3-6) and a mean average rate of 0.62 mcg/kg/h (SD 0.25). Although hypotension (76%) and bradycardia (54%) were common, only one patient required intervention. The proportion of patients with at least one episode of agitation decreased from 100% on day 0, to 88%, 69% and 63% on days 1, 2 and 3 of dexmedetomidine, respectively. The decrease was statistically significant difference between days 0 and 2 as well as between days 0 and 3. Concomitant use of propofol and benzodiazepines also decreased over the course of dexmedetomidine treatment. CONCLUSION: Dexmedetomidine use was safe and associated with a reduction in agitation in traumatic brain injury patients in the 96 hours following its initiation.

Agitation, confusion, and aggression in critically ill traumatic brain injury-a pilot cohort study (ACACIA-PILOT).

BACKGROUND: Agitated behaviors are problematic in intensive care unit (ICU) patients recovering from traumatic brain injury (TBI) as they create substantial risks and challenges for healthcare providers. To date, there have been no studies evaluating their epidemiology and impact in the ICU. Prior to planning a multicenter study, assessment of recruitment, feasibility, and pilot study procedures is needed. In this pilot study, we aimed to evaluate the feasibility of conducting a large multicenter prospective cohort study. METHODS: This feasibility study recruited adult patients admitted to the ICU with TBI and an abnormal cerebral CT scan. In all patients, we documented Richmond Agitation Sedation Score (RASS) and agitated behaviors every 8-h nursing shift using a dedicated tool documenting 14 behaviors. Our feasibility objectives were to obtain consent from at least 2 patients per month; completion of screening logs for agitated behaviors by bedside nurses for more than 90% of 8-h shifts; completion of data collection in an average of 6 h or less; and obtain 6-month follow-up for surviving patients. The main clinical outcome was the incidence of agitation and individual agitated behaviors. RESULTS: In total, 47 eligible patients were approached for inclusion and 30 (64% consent rate) were recruited over a 10-month period (3 patients/month). In total, 794 out of 827 (96%) possible 8-h periods of agitated behavior logs were completed by bedside nurses, with a median of 24 observations (IQR 28.0) per patient. During the ICU stay, 17 of 30 patients developed agitation (56.7%; 95% CI 0.37-0.75) defined as RASS ≥ 2 during at least one observation period and for a median of 4 days (IQR 5.5). At 6 months post-TBI, among the 24 available patients, an unfavorable score (GOS-E < 5 including death) was reported in 12 patients (50%). In the 14 patients who were alive and available at 6 months, the median QOLIBRI score was 74.5 (IQR 18.5). CONCLUSIONS: This study demonstrates the feasibility of conducting a larger cohort study to evaluate the epidemiology and impact of agitated behaviors in critically ill TBI patients. This study also shows that agitated behaviors are frequent and are associated with adverse events.

Physicochemical Compatibility of Dexmedetomidine With Parenteral Nutrition.

BACKGROUND: Dexmedetomidine is an α2-agonist used as a sedative agent in the intensive care setting. Simultaneous administration of dexmedetomidine and parenteral nutrition (PN) may be required. The aim of this study was to evaluate the physicochemical compatibility of dexmedetomidine Y-site administered with PN. METHODS: Three PN and 3 dexmedetomidine solutions were compounded. The tested infusion rate for PN was 66 mL/h. For dexmedetomidine, we considered the initial and maximum infusion rates (0.7 and 1.4 µg/kg/h) detailed in the data sheet. Taking this into account and considering a weight range of 55-95 kg, we tested 2 dexmedetomidine infusion rates (10 and 36 mL/h). The samples obtained were examined visually against light. pH was analyzed with a pH meter. Mean fat droplet diameter was determined by dynamic light scattering. Quantification of dexmedetomidine concentration was carried out by ultraperformance liquid chromatography-high-resolution mass spectrometry. For each PN-dexmedetomidine admixture, tests were performed in triplicate. RESULTS: No alterations were observed by visual inspection. Average pH was 6.25 ± 0.01. Droplet diameter remained below 500 nm (298 ± 10 nm for 10-mL/h rate and 303 ± 5 nm for 36-mL/h rate). Dexmedetomidine concentrations at t = 0 were 519 ± 31 ng/mL and 1391 ± 90 ng/mL for 10- and 36-mL/h infusion rates, respectively. At t = 24 hours, the concentrations obtained were 494 ± 22 and 1332 ± 102 ng/mL, which translates into ≥90% of the initial concentrations. CONCLUSION: Dexmedetomidine is physicochemically compatible with PN during simulated Y-site administration at the tested infusion rates.

Drug Shortages in Canada and Selected European Countries: A Cross-Sectional, Institution-Level Comparison.

BACKGROUND: Drug shortages represent a complex global problem affecting patients and health care professionals on a daily basis. OBJECTIVES: To identify, describe, and compare drug shortages in health care facilities in Canada and 4 European countries in early 2018. METHODS: A descriptive cross-sectional study was conducted in 1 hospital in each of 5 countries: Canada, France, Belgium, Spain, and Switzerland. Over a 4-week period, shortage data were collected daily by each hospital using a standardized grid and a standard process. RESULTS: From January 8 to February 2, 2018, there were a total of 84 shortages (median duration 32 days) in the Canadian hospital, 62 shortages (median duration 9 days) in the French hospital, 46 shortages (median duration 37 days) in the Belgian hospital, 28 shortages (median duration 25 days) in the Spanish hospital, and 98 shortages (median duration 68 days) in the Swiss hospital. The number of manufacturers implicated in the shortages was 28 for the Canadian hospital, 30 for the French hospital, 19 for the Belgian hospital, 16 for the Spanish hospital, and 42 for the Swiss hospital. Most of the shortages involved parenteral drugs, with both innovative and generic manufacturers being affected. Most therapeutic classes were affected by shortages to some extent, with the top 3 classes being anti-infective agents (accounting for 21.1% of shortages overall), central nervous system drugs (11.3%), and cardiovascular drugs (8.2%). CONCLUSIONS: Drug shortages occurred almost daily in all of the study hospitals. Across the 5 hospitals, the frequency of shortages varied by a factor of 3, which may imply similar variability at the national level. All stakeholders should work more diligently to prevent and manage drug shortages.

CONTEXTE: Les pénuries de médicaments représentent un problème mondial complexe qui touche quotidiennement les patients et les professionnels de la santé. OBJECTIFS: Recenser, décrire et comparer les pénuries de médicaments ayant eu lieu au début de 2018 dans des établissements de soins de santé du Canada et de quatre pays d'Europe. MÉTHODES: Une étude descriptive et transversale a été menée dans un hôpital de chacun des cinq pays suivants: le Canada, la France, la Belgique, l'Espagne et la Suisse. Sur une période de quatre semaines, chaque hôpital a recueilli quotidiennement les données sur les pénuries à l'aide d'une grille et d'un processus normalisés. RÉSULTATS: Pour la période allant du 8 janvier au 2 février 2018, on a recensé 84 pénuries (durée médiane de 32 jours) dans l'hôpital canadien, 62 pénuries (durée médiane de 9 jours) dans l'hôpital français, 46 pénuries (durée médiane de 37 jours) dans l'hôpital belge, 28 pénuries (durée médiane de 25 jours) dans l'hôpital espagnol et 98 pénuries (durée médiane de 68 jours) dans l'hôpital suisse. Vingt-huit (28) fabricants étaient impliqués dans les cas de pénuries dans l'hôpital canadien, 30 dans l'hôpital français, 19 dans l'hôpital belge, 16 dans l'hôpital espagnol et 42 dans l'hôpital suisse. La plupart des pénuries touchaient les médicaments parentéraux et mettaient en cause tant les fabricants de médicaments novateurs que ceux de médicaments génériques. Les pénuries ont affecté d'une manière ou d'une autre la plupart des classes de médicaments, mais les trois classes les plus touchées étaient les agents anti-infectieux (21,1 %) les médicaments agissant sur le système nerveux central (11,3 %) et les agents cardiovasculaires (8,2 %). CONCLUSIONS: Des pénuries survenaient presque quotidiennement dans chaque hôpital de l'étude. Dans l'ensemble des hôpitaux, la fréquence des pénuries variait selon un facteur de trois, ce qui pourrait se traduire par une variabilité semblable à l'échelle nationale. Toutes les parties prenantes doivent travailler avec plus d'ardeur à la prévention et à la gestion des pénuries de médicaments.

Role and impact of pharmacists in Spain: a scoping review.

Background The role of the pharmacist has evolved greatly over the last decades, expanding to patient-oriented activities, administrative tasks and public health functions. However, considerable differences emerge across regions. Aim of the review To gather evidence in order to describe and highlight the different characteristics of the pharmacists' role and the impact of their activities in Spain. Method A review of the existing literature was conducted. The literature search was undertaken in PubMed between 01/01/2006 and 15/08/2017. Results were screened and reviewed to extract previously established criteria such as author(s), publication year, language, study design, setting, pharmaceutical activity, patient care programs, targeted diseases and intervention description using DEPICT2 tool. Pharmaceutical intervention were classified into eight outcome measures and categorized by types of outcomes reported: descriptive or impact evaluation regarding the effect of the service (positive, neutral or negative). Results The search strategy resulted in 473 articles and 108 articles met the inclusion criteria. The most common design was observational (n = 76, 70%). Most articles were published after 2011 (75%), in English (69%). Studies were conducted in hospitals (60%) and community pharmacies (30%). Of the 24 pharmaceutical activities identified, medication review was the activity most frequently studied (n = 42), followed by patient education (n = 29), risk and prevention (n = 27) and medication reconciliation (n = 19). Only 39 articles (36%) had outcome measures with impact evaluation. Of the 223 impact outcome measures, 48% (107/223) had a positive effect. Conclusion This review shows the substantial scientific production focusing on pharmacy practice in Spain over the last years. The evidence reviewed reflects the pharmacist role at various professional settings, providing a wide variety of activities on diverse targeted diseases and patient care programs, in line with the increasing specialization of clinical pharmacists over the last years.
