Facilitating guideline implementation in primary health care practices
Introduction: Many patients continue to receive suboptimal services, inappropriate, unsafe, and costly care. Underutilization of research by health professionals is a common problem in the primary care setting. Although many theoretical frameworks can be used to help address such evidence-practice gaps, health care professionals may not be aware of the benefits of frameworks or of the most appropriate ones for their context and thus, may be faced with the challenge of selecting and using the most relevant one. Aim: The aim of this article was to describe the process used to adapt a knowledge translation framework to meet the local needs of health professionals working in one large primary care setting. Methods: The authors developed a 5-step approach for guideline implementation. This approach was informed by prior research and the authorsâ experiences in supporting multidisciplinary teams of health care professionals during the implementation of evidence-based clinical guidelines into primary care practices. To ensure that the 5-step approach was practical and suitable for the context of guideline implementation by multidisciplinary teams in primary health care, the implementation team adapted the âknowledge-to-actionâ framework using a multistep process. Results: The implementation approach consisted of the following 5 steps: identification, context analysis, development of implementation plan, evaluation, and sustainability. All 5 steps were described alongside details about a national low back pain project. Discussion: This article describes a collaborative, grassroots process that addressed an identified need in one complex context by adapting a knowledge translation framework to meet the local needs of health professionals working in primary care settings. Existing implementation frameworks may be too complex or abstract for use in busy clinical contexts. The 5-step approach presented in this paper resulted in practical steps that are more readily understood by health care professionals and staff on âthe groundâ. © The Author(s) 2020
Huge variability in restrictions of mobilization for patients with aneurysmal subarachnoid hemorrhage - A European survey of practice.
INTRODUCTION
One of the major goals of neurointensive care is to prevent secondary injuries following aSAH. Bed rest and patient immobilization are practiced in order to decrease the risk of DCI.
RESEARCH QUESTION
To explore the current practices in place concerning the management of patients with aSAH, specifically, protocols and habits regarding restrictions of mobilization and HOB positioning.
MATERIAL AND METHODS
A survey was designed, modified, and approved by the panel of the Trauma & Critical Care section of the EANS to cover the practice of restrictions of patient mobilization and HOB positioning in patients with aSAH.
RESULTS
Twenty-nine physicians from 17 countries completed the questionnaire. The majority (79.3%) stated that non-secured aneurysm and the presence of an EVD were the factors related to the establishment of restriction of mobilization. The average duration of the restriction varied widely ranging between 1 and 21 days. The presence of an EVD (13.8%) was found to be the main reason to recommend restriction of HOB elevation. The average duration of restriction of HOB positioning ranged between 3 and 14 days. Rebleeding or complications related to CSF over-drainage were found to be related to these restrictions.
DISCUSSION AND CONCLUSION
Restriction of patient mobilization regimens vary widely in Europe. Current limited evidence does not support an increased risk of DCI rather the early mobilization might be beneficial. Large prospective studies and/or the initiative of a RCT are needed to understand the significance of early mobilization on the outcome of patients with aSAH
Feasibility of individualised severe traumatic brain injury management using an automated assessment of optimal cerebral perfusion pressure: the COGiTATE phase II study protocol.
INTRODUCTION: Individualising therapy is an important challenge for intensive care of patients with severe traumatic brain injury (TBI). Targeting a cerebral perfusion pressure (CPP) tailored to optimise cerebrovascular autoregulation has been suggested as an attractive strategy on the basis of a large body of retrospective observational data. The objective of this study is to prospectively assess the feasibility and safety of such a strategy compared with fixed thresholds which is the current standard of care from international consensus guidelines. METHODS AND ANALYSIS: CPPOpt Guided Therapy: Assessment of Target Effectiveness (COGiTATE) is a prospective, multicentre, non-blinded randomised, controlled trial coordinated from Maastricht University Medical Center, Maastricht (The Netherlands). The other original participating centres are Cambridge University NHS Foundation Trust, Cambridge (UK), and University Hospitals Leuven, Leuven (Belgium). Adult severe TBI patients requiring intracranial pressure monitoring are randomised within the first 24âhours of admission in neurocritical care unit. For the control arm, the CPP target is the Brain Trauma Foundation guidelines target (60-70âmm Hg); for the intervention group an automated CPP target is provided as the CPP at which the patient's cerebrovascular reactivity is best preserved (CPPopt). For a maximum of 5 days, attending clinicians review the CPP target 4-hourly. The main hypothesis of COGiTATE are: (1) in the intervention group the percentage of the monitored time with measured CPP within a range of 5âmm Hg above or below CPPopt will reach 36%; (2) the difference in between groups in daily therapy intensity level score will be lower or equal to 3. ETHICS AND DISSEMINATION: Ethical approval has been obtained for each participating centre. The results will be presented at international scientific conferences and in peer-reviewed journals.

International comparative study of low back pain care pathways and analysis of key interventions
Purpose Low back pain (LBP) is a major public health problem worldwide. Significant practice variation exists despite guidelines, including strong interventionist focus by some practitioners. Translation of guidelines into pathways as integrated treatment plans is a next step to improve implementation. The goal of the present study was to analyze international examples of LBP pathways in order to identify key interventions as building elements for care pathway for LBP and radicular pain. Methods International examples of LBP pathways were searched in literature and grey literature. Authors of pathways were invited to fill a questionnaire and to participate in an in-depth telephone interview. Pathways were quantitatively and qualitatively analyzed, to enable the identification of key interventions to serve as pathway building elements. Results Eleven international LBP care pathways were identified. Regional pathways were strongly organized and included significant training efforts for primary care providers and an intermediate level of caregivers in between general practitioners and hospital specialists. Hospital pathways had a focus on multidisciplinary collaboration and stepwise approach trajectories. Key elements common to all pathways included the consecutive screening for red flags, radicular pain and psychosocial risk factors, the emphasis on patient empowerment and self-management, the development of evidence-based consultable protocols, the focus on a multidisciplinary work mode and the monitoring of patient-reported outcome measures. Conclusion Essential building elements for the construction of LBP care pathways were identified from a transversal analysis of key interventions in a study of 11 international examples of LBP pathways
Early surgery versus conservative treatment in patients with traumatic intracerebral hematoma:a CENTER-TBI study
Purpose: Evidence regarding the effect of surgery in traumatic intracerebral hematoma (t-ICH) is limited and relies on the STITCH(Trauma) trial. This study is aimed at comparing the effectiveness of early surgery to conservative treatment in patients with a t-ICH. Methods: In a prospective cohort, we included patients with a large t-ICH (< 48 h of injury). Primary outcome was the Glasgow Outcome Scale Extended (GOSE) at 6 months, analyzed with multivariable proportional odds logistic regression. Subgroups included injury severity and isolated vs. non-isolated t-ICH. Results: A total of 367 patients with a large t-ICH were included, of whom 160 received early surgery and 207 received conservative treatment. Patients receiving early surgery were younger (median age 54 vs. 58 years) and more severely injured (median Glasgow Coma Scale 7 vs. 10) compared to those treated conservatively. In the overall cohort, early surgery was not associated with better functional outcome (adjusted odds ratio (AOR) 1.1, (95% CI, 0.6â1.7)) compared to conservative treatment. Early surgery was associated with better outcome for patients with moderate TBI and isolated t-ICH (AOR 1.5 (95% CI, 1.1â2.0); P value for interaction 0.71, and AOR 1.8 (95% CI, 1.3â2.5); P value for interaction 0.004). Conversely, in mild TBI and those with a smaller t-ICH (< 33 cc), conservative treatment was associated with better outcome (AOR 0.6 (95% CI, 0.4â0.9); P value for interaction 0.71, and AOR 0.8 (95% CI, 0.5â1.0); P value for interaction 0.32). Conclusions: Early surgery in t-ICH might benefit those with moderate TBI and isolated t-ICH, comparable with results of the STITCH(Trauma) trial.</p
Low-resolution pressure reactivity index and its derived optimal cerebral perfusion pressure in adult traumatic brain injury: a CENTER-TBI study
Abstract: Background: After traumatic brain injury (TBI), brain tissue can be further damaged when cerebral autoregulation is impaired. Managing cerebral perfusion pressure (CPP) according to computed âoptimal CPPâ values based on cerebrovascular reactivity indices might contribute to preventing such secondary injuries. In this study, we examined the discriminative value of a low-resolution long pressure reactivity index (LPRx) and its derived âoptimal CPPâ in comparison to the well-established high-resolution pressure reactivity index (PRx). Methods: Using the Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) study dataset, the association of LPRx (correlation between 1-min averages of intracranial pressure and arterial blood pressure over a moving time frame of 20 min) and PRx (correlation between 10-s averages of intracranial pressure and arterial blood pressure over a moving time frame of 5 min) to outcome was assessed and compared using univariate and multivariate regression analysis. âOptimal CPPâ values were calculated using a multi-window algorithm that was based on either LPRx or PRx, and their discriminative ability was compared. Results: LPRx and PRx were both significant predictors of mortality in univariate and multivariate regression analysis, but PRx displayed a higher discriminative ability. Similarly, deviations of actual CPP from âoptimal CPPâ values calculated from each index were significantly associated with outcome in univariate and multivariate analysis. âOptimal CPPâ based on PRx, however, trended towards more precise predictions. Conclusions: LPRx and its derived âoptimal CPPâ which are based on low-resolution data were significantly associated with outcome after TBI. However, they did not reach the discriminative ability of the high-resolution PRx and its derived âoptimal CPP.â Nevertheless, LPRx might still be an interesting tool to assess cerebrovascular reactivity in centers without high-resolution signal monitoring.

Evaluation of the relationship between slow-waves of intracranial pressure, mean arterial pressure and brain tissue oxygen in TBI: a CENTER-TBI exploratory analysis
Abstract: Brain tissue oxygen (PbtO2) monitoring in traumatic brain injury (TBI) has demonstrated strong associations with global outcome. Additionally, PbtO2 signals have been used to derive indices thought to be associated with cerebrovascular reactivity in TBI. However, their true relationship to slow-wave vasogenic fluctuations associated with cerebral autoregulation remains unclear. The goal of this study was to investigate the relationship between slow-wave fluctuations of intracranial pressure (ICP), mean arterial pressure (MAP) and PbtO2 over time. Using the Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) high resolution ICU sub-study cohort, we evaluated those patients with recorded high-frequency digital intra-parenchymal ICP and PbtO2 monitoring data of a minimum of 6 h in duration. Digital physiologic signals were processed for ICP, MAP, and PbtO2 slow-waves using a moving average filter to decimate the high-frequency signal. The first 5 days of recording were analyzed. The relationship between ICP, MAP and PbtO2 slow-waves over time were assessed using autoregressive integrative moving average (ARIMA) and vector autoregressive integrative moving average (VARIMA) modelling, as well as Granger causality testing. A total of 47 patients were included. The ARIMA structure of ICP and MAP were similar in time, where PbtO2 displayed different optimal structure. VARIMA modelling and IRF plots confirmed the strong directional relationship between MAP and ICP, demonstrating an ICP response to MAP impulse. PbtO2 slow-waves, however, failed to demonstrate a definite response to ICP and MAP slow-wave impulses. These results raise questions as to the utility of PbtO2 in the derivation of cerebrovascular reactivity measures in TBI. There is a reproducible relationship between slow-wave fluctuations of ICP and MAP, as demonstrated across various time-series analytic techniques. PbtO2 does not appear to reliably respond in time to slow-wave fluctuations in MAP, as demonstrated on various VARIMA models across all patients. These findings suggest that PbtO2 should not be utilized in the derivation of cerebrovascular reactivity metrics in TBI, as it does not appear to be responsive to changes in MAP in the slow-waves. These findings corroborate previous results regarding PbtO2 based cerebrovascular reactivity indices

Compensatory-reserve-weighted intracranial pressure versus intracranial pressure for outcome association in adult traumatic brain injury: a CENTER-TBI validation study
Abstract: Background: Compensatory-reserve-weighted intracranial pressure (wICP) has recently been suggested as a supplementary measure of intracranial pressure (ICP) in adult traumatic brain injury (TBI), with a single-center study suggesting an association with mortality at 6 months. No multi-center studies exist to validate this relationship. The goal was to compare wICP to ICP for association with outcome in a multi-center TBI cohort. Methods: Using the Collaborative European Neuro Trauma Effectiveness Research in TBI (CENTER-TBI) high-resolution intensive care unit (ICU) cohort, we derived ICP and wICP (calculated as wICP = (1 â RAP) Ă ICP; where RAP is the compensatory reserve index derived from the moving correlation between pulse amplitude of ICP and ICP). Various univariate logistic regression models were created comparing ICP and wICP to dichotomized outcome at 6 to 12 months, based on Glasgow Outcome ScoreâExtended (GOSE) (alive/deadâGOSE â„ 2/GOSE = 1; favorable/unfavorableâGOSE 5 to 8/GOSE 1 to 4, respectively). Models were compared using area under the receiver operating curves (AUC) and p values. Results: wICP displayed higher AUC compared to ICP on univariate regression for alive/dead outcome compared to mean ICP (AUC 0.712, 95% CI 0.615â0.810, p = 0.0002, and AUC 0.642, 95% CI 0.538â746, p < 0.0001, respectively; no significant difference on Delongâs test), and for favorable/unfavorable outcome (AUC 0.627, 95% CI 0.548â0.705, p = 0.015, and AUC 0.495, 95% CI 0.413â0.577, p = 0.059; significantly different using Delongâs test p = 0.002), with lower wICP values associated with improved outcomes (p < 0.05 for both). These relationships on univariate analysis held true even when comparing the wICP models with those containing both ICP and RAP integrated area under the curve over time (p < 0.05 for all via Delongâs test). Conclusions: Compensatory-reserve-weighted ICP displays superior outcome association for both alive/dead and favorable/unfavorable dichotomized outcomes in adult TBI, through univariate analysis. Lower wICP is associated with better global outcomes. The results of this study provide multi-center validation of those seen in a previous single-center study
