Long-term cognitive impairment and delirium in intensive care: A prospective cohort study

Background

Whilst there is a growing body of research exploring the effect of delirium in intensive care unit (ICU) patients, the relationship between patient delirium and long-term cognitive impairment has not been investigated in settings where low rates of delirium have been reported.

A touchy topic: tactile assessment among pediatric therapists

Purpose: Tactile impairments affect over 77% of children with unilateral cerebral palsy (CP). This study aimed to examine the current practices of pediatric therapists in relation to tactile assessment and the barriers to carrying out tactile assessment in children with CP.

Method: The study was in two parts. In part one, pediatric therapists (n?=?35) completed a questionnaire detailing their current knowledge and the use of tactile assessments in children. In part two, therapists (n?=?12) completed a questionnaire based on the Theoretical Domains Framework examining the barriers and facilitators to completing tactile assessments in clinical practice.

Results: Most therapists (over 90%) carry out tactile assessments in the minority (less than 25%) of children with CP that they treat. Therapists reported the need for improved knowledge/skills (n?=?24) and confidence (n?=?19) in carrying out tactile assessments, alongside the provision of necessary equipment (n?=?17). Qualitative reports also suggested that organizational assessment guidelines and templates may facilitate the implementation of tactile assessment.

Conclusions: A multi-faceted knowledge translation strategy to address the barriers to tactile assessment among pediatric therapists needs to be developed.

• Implications for rehabilitation

• Pediatric occupational therapists and physiotherapists may not be completing tactile assessments according to current evidence-based recommendations.

• Therapists identified five main barriers, including a lack of knowledge, skills, belief in their capabilities (confidence), behavioral regulation (organizational procedures), and environmental context (e.g., equipment).

• Therapists recommended several potential facilitators, including access to necessary equipment, procedures, record sheets, training in tactile assessments, and research supporting related interventions.

• Service providers are encouraged to develop multi-faceted knowledge translation strategies that address these barriers and maximize facilitators.

     

Evaluation of susceptibility testing methods for Burkholderia cepacia complex: a comparison of broth microdilution,agar dilution,gradient strip and EUCAST disc diffusion

ObjectivesTo evaluate the accuracy and reproducibility of antimicrobial susceptibility testing methods in Burkholderia cepacia complex (BCC).MethodsMinocycline, ciprofloxacin, trimethoprim/sulphamethoxazole, meropenem, ceftazidime and chloramphenicol were tested against 155 BCC strains using broth microdilution at 35 ± 1°C (BMD₃₅) in triplicate, then BMD at 30 ± 1°C (BMD₃₀), agar dilution at 30°C and 35°C (AD₃₀ and AD₃₅), gradient strip (GS) and EUCAST standardized disc diffusion (DD) testing methods once.ResultsBMD₃₅ reproducibility ranged from 70% to 84.5% for all agents. Correlations of MICs from BMD₃₅ with BMD₃₀ ranged from 63% to 85%, with AD₃₅ from 32.9% to 87% and with GS methods from 36% to 83.9%. Essential agreement (EA) of MICs by GS with BMD₃₅ ranged from 62.6% (trimethoprim-sulphamethoxazole) to 83.9% (minocycline). EA of EUCAST DD zone diameters using CLSI breakpoint criteria was between 85.8% and 97.4%, however Very Major Errors (VME) for trimethoprim/sulphamethoxazole were 31%.ConclusionsBMD at 35 ± 1°C was poorly reproducible for most agents and no method showed acceptable performance. Of particular concern were the GS results. Although this is the most commonly used method for determining MICs in laboratories, there was poor correlation with BMD₃₅ for meropenem and trimethoprim/sulphamethoxazole. EUCAST DD correlated poorly with BMD₃₅ MICs. This study confirms that no susceptibility method is capable of providing reproducible and accurate MICs when testing BCC.
