The role of centre and country factors on process and outcome indicators in critically ill patients with hospital-acquired bloodstream infections

PURPOSE

The primary objective of this study was to evaluate the associations between centre/country-based factors and two important process and outcome indicators in patients with hospital-acquired bloodstream infections (HABSI).

METHODS

We used data on HABSI from the prospective EUROBACT-2 study to evaluate the associations between centre/country factors on a process or an outcome indicator: adequacy of antimicrobial therapy within the first 24 h or 28-day mortality, respectively. Mixed logistical models with clustering by centre identified factors associated with both indicators.

RESULTS

Two thousand two hundred nine patients from two hundred one intensive care units (ICUs) were included in forty-seven countries. Overall, 51% (n = 1128) of patients received an adequate antimicrobial therapy and the 28-day mortality was 38% (n = 839). The availability of therapeutic drug monitoring (TDM) for aminoglycosides everyday [odds ratio (OR) 1.48, 95% confidence interval (CI) 1.03-2.14] or within a few hours (OR 1.79, 95% CI 1.34-2.38), surveillance cultures for multidrug-resistant organism carriage performed weekly (OR 1.45, 95% CI 1.09-1.93), and increasing Human Development Index (HDI) values were associated with adequate antimicrobial therapy. The presence of intermediate care beds (OR 0.63, 95% CI 0.47-0.84), TDM for aminoglycoside available everyday (OR 0.66, 95% CI 0.44-1.00) or within a few hours (OR 0.51, 95% CI 0.37-0.70), 24/7 consultation of clinical pharmacists (OR 0.67, 95% CI 0.47-0.95), percentage of vancomycin-resistant enterococci (VRE) between 10% and 25% in the ICU (OR 1.67, 95% CI 1.00-2.80), and decreasing HDI values were associated with 28-day mortality.

CONCLUSION

Centre/country factors should be targeted for future interventions to improve management strategies and outcome of HABSI in ICU patients.

"Burns Behind Bars": A 10-year review and cost analysis of burn injuries in prison inmates presenting to a regional burns centre, and the role of the burns outreach service

INTRODUCTION

From 85348 inmates in England and Wales, over 26,000 incidents of assault and 40,000 of self-harm were reported from within prisons in 2016. This study focuses primarily on burn injuries in prison, determining the predominant aetiology as well as clinical outcomes of these injuries.

METHODS

Data was retrieved retrospectively and a case series performed, including all burns referred from regional prisons to our centre from 2007 to 2017 and comprising patient demographics, mechanism of injury, total body surface area affected, management, and outcome. Cost analysis of care was conducted using a previously published framework.

RESULTS

18 cases from three regional prisons were recorded, with 67% from a single prison. Referrals rose exponentially over time, with 44% occurring in 2017. 94% were scald burns, and 56% secondary to assault, primarily through the use of kettles and mostly targeting the face and trunk. The mean TBSA of burn was 2.89% (<1-8%), and 80% received first aid. 72.2% were admitted to hospital for an average of 4 days. All burns were managed nonoperatively with dressings and underwent on average 2 outpatient reviews (1-8).

DISCUSSION

The disproportionate spread of referrals across the prisons correlates partly with the respective populations, but may also represent contrasting medical provisions. The recurring method of assault reflects the relative ease of access to hot water as a harmful agent, predominantly presenting with scalds affecting more critical areas, and with concurrent physical trauma in nearly half of cases which presents management challenges.

CONCLUSION

Targeted education is recommended to reduce the incidence and ensure adequate management of burns in prison, referrals for which are demonstrably rising. Accordingly, the Burns Outreach team can provide training to in-house prison health staff and review referrals to specialist Burns services, aiming to ensure equitable care while alleviating costs associated with transfer to and management in hospital.

Effect of central and peripheral cone- and rod-specific stimulation on the pupillary light reflex

Purpose

To assess the effect of central and peripheral stimulation on the pupillary light reflex. The aim was to detect possible differences between cone- and rod-driven reactions.

Methods

Relative maximal pupil constriction amplitude (relMCA) and latency to constriction onset (latency) to cone- and rod-specific stimuli of 30 healthy participants (24 ± 5 years (standard deviation)) were measured using chromatic pupil campimetry. Cone- and rod-specific stimuli had different intensities and wavelengths according to the Standards in Pupillography. Five filled circles with radii of 3°, 5°, 10°, 20° and 40° and four rings with a constant outer radius of 40° and inner radii of 3°, 5°, 10° and 20° were used as stimuli.

Results

For cone-and rod-specific stimuli, relMCA increased with the stimulus area for both, circles and rings. However, increasing the area of a cone-specific ring by minimizing its inner radius with constant outer radius increased relMCA significantly stronger than the same did for a rod-specific ring. For cones and rods, a circle stimulus with a radius of 40° created a lower relMCA than the summation of the relMCAs to the corresponding ring and circle stimuli which combined create a 40° circle-stimulus. Latency was longer for rods than for cones. It decreased with increasing stimulus area for circle stimuli while it stayed nearly constant with increasing ring stimulus area for cone- and rod-specific stimuli.

Conclusion

The effect of central stimulation on relMCA is more dominant for cone-specific stimuli than for rod-specific stimuli while latency dynamics are similar for both conditions.

[Definition of endometriosis expert centres]

OBJECTIVES

The Collège national des gynécologues obstétriciens français (CNGOF), in agreement with the Société de chirurgie gynécologique et pelvienne (SCGP), has set up a commission in 2017 to define endometriosis expert centres, with the aim of optimizing endometriosis care in France.

METHODS

The committee included members from university and general hospitals as well as private facilities, representing medical, surgical and radiological aspects of endometriosis care. Opinion of endometriosis patients' associations was obtained prior to writing this work. The final text was presented and unanimously validated by the members of the CNGOF Board of Directors at its meeting of October 13, 2017.

RESULTS

Based on analysis of current management of endometriosis and the last ten years opportunities in France, the committee has been able to define the contours of endometriosis expert centres. The objectives, production specifications, mode of operation, missions and funding for these centres were described. The following missions have been specifically defined: territorial organization, global and referral care, communication and teaching as well as research and evaluation.

CONCLUSION

Because of its daily impact for women and its economic burden in France, endometriosis justifies launching of expert centres throughout the country with formal accreditation by health authorities, ideally as part of the National Health Plan.

Cancer Control Algorithm

Curing cancer by controlling the growth of the cancer cell is the objective of this paper. The growth of the cancer cell is analysed by the optimization programming. The algorithm is proposed for minimizing the rate of growth of the cancer cell. Hence the chaotic cancer became structured for the further research. This is an extended work of Warburg [1], where he defined the centre of the cancer cell, known by Warburg effect, but here we control the increasing radius of the cancer circle by the proposed Cancer Control Algorithm.

Improving core surgical training in a major trauma centre

INTRODUCTION

English Major Trauma Centres (MTCs) were established in April 2012. Increased case volume and complexity has influenced trauma and orthopaedic (T&O) core surgical training in these centres.

OBJECTIVES

To determine if T&O core surgical training in MTCs meets Joint Committee on Surgical Training (JCST) quality indicators including performance of T&O operative procedures and consultant supervised session attendance.

METHODS

An audit cycle assessing the impact of a weekly departmental core surgical trainee rota. The rota included allocated timetabled sessions that optimised clinical and surgical learning opportunities. Intercollegiate Surgical Curriculum Programme (ISCP) records for T&O core surgical trainees at a single MTC were analysed for 8 months pre and post rota introduction. Outcome measures were electronic surgical logbook evidence of leading T&O operative procedures and consultant validated work-based assessments (WBAs).

RESULTS

Nine core surgical trainees completed a 4 month MTC placement pre and post introduction of the core surgical trainee rota. Introduction of core surgical trainee rota significantly increased the mean number of T&O operative procedures led by a core surgical trainee during a 4 month MTC placement from 20.2 to 34.0 (p<0.05). The mean number of hip hemiarthroplasty procedures led by a core surgical trainee during a 4 month MTC placement was significantly increased (0.3 vs 2.4 [p=0.04]). Those of dynamic hip screw fixation (2.3 vs 3.6) and ankle fracture fixation (0.7 vs 1.6) were not. Introduction of a core surgical trainee rota significantly increased the mean number of consultant validated WBAs completed by a core surgical trainee during a 4 month MTC placement from 1.7 to 6.6 (p<0.0001).

CONCLUSIONS

Introduction of a departmental core surgical trainee rota utilising a 'problem-based' model can significantly improve T&O core surgical training in MTCs.

The first center for evidence-based medicine in Lithuania: an opportunity to change culture and improve clinical practice

In post-Soviet countries, where medical practice largely relies on experience alone, the incorporation of the best research evidence in clinical practice is limited. In order to promote the awareness and utilization of evidence-based medicine (EBM) among Lithuanian doctors, we organized EBM conferences in each of the two Lithuanian medical schools. More than 500 medical professionals and students attended the conferences in Vilnius (2013) and Kaunas (2014) demonstrating that there is a high demand for formal EBM teaching. Building on the success of these seminal conferences, and to start addressing the lack of EBM practice in the country, the first Lithuanian Centre for Evidence-Based Medicine was established at Vilnius University Medical Faculty in 2014. The Centre will focus on the implementation of EBM teaching in medical school curriculum, formulating management guidelines, writing systematic reviews and supporting Lithuanian authors in doing so.

Evidence of a relational spatial strategy in learning the centre of enclosures in human children (Homo sapiens)

Three- to five-year-old children were trained to localize a sensor hidden underneath the floor, in the centre of a square-shaped enclosure (1.5m×1.5m). Walking over the sensor caused a pleasant music to be played in the environment, thus engaging children in a playful spatial search. Children easily learned to find the centre of the training environment starting from random positions. After training, children were tested in enclosures of different size and/or shape: a larger square-shaped enclosure (3m×3m), a rectangle-shaped enclosure (1.5m×3m), an equilateral triangle-shaped enclosure (side 3m) and an isosceles triangle-shaped enclosure (base 1.5m; sides 3m). Children searched in the central region of the enclosures, their precision varying as a function of the similarity of the testing enclosure's shape to the shape of the training enclosure. This suggests that a relational spatial strategy was used, and that it depended on the encoding of geometrical shape. This result highlights a distinctive role of the geometric centre of enclosed spaces in place learning in children, as already observed in nonhuman species.
