    Abstract Objective: To evaluate the effect of level 1, high observation beds (HOBs) compared with high dependency unit (HDU) and neurosurgical intensive care unit (NICU) admission on service provision, such as cancelled operations, and healthcare costs.
    Methods: A retrospective, observational, single-centre cross-sectional study at a single, large UK neurosurgical centre. All adult patients admitted to neurosurgical HOBs between December 2021 and July 2022 were included. The list of cancelled procedures was collected from 2019 to 2022. To evaluate the impact of admission of eligible patients to HOBs, the total bed days, cost per bed day, number of admissions and cost per admission were obtained for all clinical areas the financial years 2019/2020 and 2021/2022.
    Results: 307 patients were included in the study: 59.7% of HOBs admissions were elective and 37.7% were acute; admissions were for cranial procedures or conservative treatment (64.8%), spinal (32.6%) or other (2.6%). Following admission, 73.3% of patients were stepped down to the ward prior to discharge home. Only seven patients required escalation to level-2 or level-3 care. Overall, 97% of all HOBs patients were discharged home at the end of hospital stay. Occupancy rate was 90.4%.The cost of bed day increased from ward, level 0 (£384), then level 1 (£376), to level 2 (£787-1211) and to level 3 (£1628). From 2019 to 2021, 558 operations had been cancelled, and 140 (37.8%) of 370 were estimated to have been potentially avoided by HOBs admissions due to conflict of scheduling, ward bed capacity and critical care bed capacity. In addition, a minimum total expenditure due to cancelled operations was estimated at £22 923.50 yearly on average.
    Conclusion: This study recognises HOBs growing role in the management of acutely unwell patients in ward-based environments. While recognising the associated challenges, this study highlighted the potential in reducing healthcare costs. Further studies should evaluate the impact and limitations of HOBs on patients' recovery and outcomes, compared to HDU and NICU.

    Abstract Background: Sternal wound infections represent a source of significant morbidity and mortality following median sternotomy. The use of incisional negative pressure wound therapy in prevention has yet to be elucidated.
    Methods: A retrospective study was conducted before and after a universal wound care protocol was implemented including the prophylactic use of negative pressure wound therapy (NPWT). The primary endpoint was sternal infections within 90 days of the index operation.
    Results: In the control period, there was a 3.0% rate of sternal infection within 90 days compared to 0.8% in the intervention period (p < 0.001). An odds ratio of 0.25 (95% confidence interval 0.11, 0.57; p < 0.001) in the intervention period as compared to the control period was demonstrated.
    Conclusions: The use of a standardized wound care protocol including the universal application of NPWT for patients undergoing cardiac surgery with median sternotomy was an independent predictor of decreased rates of sternal infection.

    Abstract Mathematics for Engineering has been carefully designed to provide a maths course for a wide ability range, and does not go beyond the requirements of Advanced GNVQ. It is an ideal text for any pre-degree engineering course where students require revision of the basics and plenty of practice work. Bill Bolton introduces the key concepts through examples set firmly in engineering contexts, which students will find relevant and motivating. The second edition has been carefully matched to the Curriculum 2000 Advanced GNVQ units:

    Abstract Introduction: There is wide variation in the management of simple subcutaneous abscesses in the UK and no national guidelines describing best practice. During the SARS-CoV-2 pandemic, regional or local anaesthesia (LA) use was recommended instead of general anaesthesia. This study aimed to assess the effect of anaesthetic use on outcomes following incision and drainage (I&D) of simple subcutaneous abscesses.
    Methods: Two cohorts of patients undergoing abscess incision and drainage at St. James' University Hospital in Leeds were identified retrospectively over a 14-week period before (P1) and after (P2) the introduction of the COVID-19 anaesthetic guidelines. The number of follow-up appointments for repacking and representation to healthcare services 30 days after I&D were used as surrogate endpoints for wound healing.
    Results: A total of 133 patients were included (
    Conclusions: Drainage of simple subcutaneous abscess under 5cm in diameter is safe under LA, with no significant difference in surrogate endpoints of wound healing observed in this patient cohort. Recurrent packing may not be required. Future work should explore patient-reported outcomes, including pain management, cosmesis and the cost and sustainability implications of a change in this common procedure.

    Abstract Clinical academia aims to bridge the gap between clinicians and scientists, by combining academic activity with clinical practice. The term 'clinical academics' generally refers to clinicians who have protected time within their job plans for undertaking academic activities. Engagement with academic activity by trainees is not only essential to fulfil necessary curriculum competencies, but also allows them to explore areas of interest outside of clinical practice and develop advanced academic skills. This article provides an overview of different routes into academic neurosurgery, and discusses the advantages and difficulties in pursuing this career path. It also covers the differences between postgraduate research degrees and explores the different job plan models available at consultant level. Academic neurosurgery is a rewarding career and opportunities should be made available to those who wish to explore it further. Developing academic careers may have a positive impact on wider workforce planning strategies and improve the delivery of high-quality evidence-based neurosurgical care.
