Summary Introduction Previous studies have documented poor quality CPR during real life resuscitation attempts. This study investigated whether poor quality CPR during advanced life support training ...could be contributing to poor performance in clinical practice. Methods Observational study of quality of CPR during advanced life support training courses before and after the implementation of the European Resuscitation Council Guidelines 2005 into the ALS course. The quality of chest compressions were downloaded from a manikin and direct observations of no-flow time; pre-shock pauses were recorded. Results 94 cardiac arrest simulations were studied (46 before implementation of Guidelines 2005 and 48 after). Delays in starting CPR, inadequate compression depth, prolonged interruptions of chest compressions and excessive pre-shock pauses were identified. The introduction of Guidelines 2005 resulted in improvements in the number of compressions given per minute and a reduction in no-flow time and duration of pre-shock pauses, but overall the quality of CPR performed during the ALS course remained poor. There was little evidence of performance improving over successive simulations as the course progressed. Conclusion The implementation of Guidelines 2005 into the ALS course appear to have improved the process of CPR by reducing no-flow time during simulated CPR. However, the quality of CPR during ALS training remains sub-optimal. Delays in starting CPR, inadequate compression depth, excessive interruptions in chest compressions and prolonged pre-shock pauses mirror observations from clinical practice. Strategies to improve CPR performance during ALS training should be explored and potentially may result in improvements in clinical practice.
Survival after out-of-hospital cardiac arrest is closely linked to the quality of CPR, but in real life, resuscitation during prehospital care and ambulance transport is often suboptimal. Mechanical ...chest compression devices deliver consistent chest compressions, are not prone to fatigue and could potentially overcome some of the limitations of manual chest compression. However, there is no high-quality evidence that they improve clinical outcomes, or that they are cost effective. The Prehospital Randomised Assessment of a Mechanical Compression Device In Cardiac Arrest (PARAMEDIC) trial is a pragmatic cluster randomised study of the LUCAS-2 device in adult patients with non-traumatic out-of-hospital cardiac arrest.
The primary objective of this trial is to evaluate the effect of chest compression using LUCAS-2 on mortality at 30 days post out-of-hospital cardiac arrest, compared with manual chest compression. Secondary objectives of the study are to evaluate the effects of LUCAS-2 on survival to 12 months, cognitive and quality of life outcomes and cost-effectiveness.
Ambulance service vehicles will be randomised to either manual compression (control) or LUCAS arms. Adult patients in out-of-hospital cardiac arrest, attended by a trial vehicle will be eligible for inclusion. Patients with traumatic cardiac arrest or who are pregnant will be excluded. The trial will recruit approximately 4000 patients from England, Wales and Scotland. A waiver of initial consent has been approved by the Research Ethics Committees. Consent will be sought from survivors for participation in the follow-up phase.
The trial will assess the clinical and cost effectiveness of the LUCAS-2 mechanical chest compression device.
The trial is registered on the International Standard Randomised Controlled Trial Number Registry (ISRCTN08233942).
AimTo prototype a system for identifying and monitoring those organisational processes that give rise to latent conditions that can contribute to failures in a dispensary environment.MethodsA ...proactive risk-monitoring system was prototyped during a 9-month period within the dispensary at Hereford Hospital. The system is used to identify empirically a preliminary set of Basic Problem Factors through qualitative analysis of narratives submitted by pharmacy staff about problems they encountered during their daily work. These factors are monitored and rated based on staff perceptions elicited through a questionnaire. At the concept stage, the system idea was discussed at two stakeholder workshops to ensure plausibility. A Plan–Do–Study–Act approach was used to prototype the system and to evaluate the perceived usability and perceived completeness of the system.ResultsAfter four Plan–Do–Study–Act cycles, staff were satisfied with the usability of the questionnaire and the choice of factors being monitored. In total, 11 Basic Problem Factors were identified from the narratives, 10 of which have been monitored over a period of 6 months using a questionnaire. The differences in staff perceptions were statistically not significant. The qualitative and quantitative results led to improvements that included a review of all IT equipment in the department and the clean-up of the work environment.ConclusionA system for identifying and monitoring organisational processes that give rise to latent conditions that may contribute to failures was prototyped at the dispensary at Hereford Hospital. This contributes to the organisation's efforts towards creating a proactive safety culture.
ABSTRACT
We present the bright (Vmag = 9.12), multiplanet system TOI-431, characterized with photometry and radial velocities (RVs). We estimate the stellar rotation period to be 30.5 ± 0.7 d using ...archival photometry and RVs. Transiting Exoplanet Survey Satellite (TESS) objects of Interest (TOI)-431 b is a super-Earth with a period of 0.49 d, a radius of 1.28 ± 0.04 R⊕, a mass of 3.07 ± 0.35 M⊕, and a density of 8.0 ± 1.0 g cm−3; TOI-431 d is a sub-Neptune with a period of 12.46 d, a radius of 3.29 ± 0.09 R⊕, a mass of $9.90^{+1.53}_{-1.49}$ M⊕, and a density of 1.36 ± 0.25 g cm−3. We find a third planet, TOI-431 c, in the High Accuracy Radial velocity Planet Searcher RV data, but it is not seen to transit in the TESS light curves. It has an Msin i of $2.83^{+0.41}_{-0.34}$ M⊕, and a period of 4.85 d. TOI-431 d likely has an extended atmosphere and is one of the most well-suited TESS discoveries for atmospheric characterization, while the super-Earth TOI-431 b may be a stripped core. These planets straddle the radius gap, presenting an interesting case-study for atmospheric evolution, and TOI-431 b is a prime TESS discovery for the study of rocky planet phase curves.
Abstract
Objectives: Emergency departments (EDs) routinely provide written information when a child with head injury (HI) is discharged home. This usually contains advice about recognizing signs of ...serious complications such as intracranial bleeding. This study evaluated the quality of discharge leaflets currently provided by Scottish emergency departments (EDs) by comparing them against written discharge advice recommended by the Scottish Intercollegiate Guideline Network (SIGN).
Methods: All 35 EDs in Scotland which treat children were asked to send a copy of the advice leaflet provided when a child with HI is discharged. Leaflets were evaluated by awarding scores for the inclusion of specific aspects of health information as recommended by SIGN. The inclusion of serious warning symptoms (maximum 20 points) and other advice on observation and help-seeking (maximum 21 points) was assessed.
Results: 34 EDs provided leaflets. The median score for including serious warning symptoms was 10/20. The median score for including advice regarding observation and when to seek help was 6.5/21. Several leaflets contained unclear or contradictory advice.
Conclusion: Many leaflets did not include important information recommended by SIGN guidelines. There was considerable variation in the quality and clarity of written discharge advice provided. This may reduce the ability of parents to recognize rare but serious complications. It is recommended that a standardized HI information leaflet based on SIGN guidelines be used across all Scottish EDs.
Cardiac arrest affects 30-35, 000 hospitalised patients in the UK every year. For these patients to be given the best chance of survival, high quality cardiopulmonary resuscitation (CPR) must be ...delivered, however the quality of CPR in real-life is often suboptimal. CPR feedback devices have been shown to improve CPR quality in the pre-hospital setting and post-event debriefing can improve adherence to guidelines and CPR quality. However, the evidence for use of these improvement methods in hospital remains unclear. The CPR quality improvement initiative is a prospective cohort study of the Q-CPR real-time feedback device combined with post-event debriefing in hospitalised adult patients who sustain a cardiac arrest.
The primary objective of this trial is to assess whether a CPR quality improvement initiative will improve rate of return of sustained spontaneous circulation in in-hospital-cardiac-arrest patients. The study is set in one NHS trust operating three hospital sites. Secondary objectives will evaluate: any return of spontaneous circulation; survival to hospital discharge and patient cerebral performance category at discharge; quality of CPR variables and cardiac arrest team factors.
All three sites will have an initial control phase before any improvements are implemented; site 1 will implement audiovisual feedback combined with post event debriefing, site 2 will implement audiovisual feedback only and site 3 will remain as a control site to measure any changes in outcome due to any other trust-wide changes in resuscitation practice. All adult patients sustaining a cardiac arrest and receiving resuscitation from the hospital cardiac arrest team will be included. Patients will be excluded if; they have a Do-not-attempt resuscitation order written and documented in their medical records, the cardiac arrest is not attended by a resuscitation team, the arrest occurs out-of-hospital or the patient has previously participated in this study. The trial will recruit a total of 912 patients from the three hospital sites.
This trial will evaluate patient and process focussed outcomes following the implementation of a CPR quality improvement initiative using real-time audiovisual feedback and post event debriefing.
