Abstract
Cast-in-place is the anchor’s installation method where the anchors are installed together with the casting of the concrete, while post-installed is the method of installing the anchors after the concrete has hardened, namely by drilling holes in the concrete with a concrete drill and then injecting the holes with chemical epoxy paste then immersing the anchors to the holes. In general, concrete drilled holes will produce a plain concrete surface, while drill bit extractor concrete (DBEC) will produce screw-textured concrete holes which are expected to increase the pullout capacity of the post-installed anchor.
The pullout capacity test of cast-in-place, post-installed, and post-installed (DBEC) anchor studs 12x160 mm anchors planted with various depths (hef) of 70 mm, 80 mm, 90 mm, and 100 mm injected with chemical epoxy paste in the borehole concrete and drill bit extractor concrete (DBEC). The pullout capacity of the post-installed with drilled holes concrete (concrete drill model) and pullout capacity drill bit extractor concrete (DBEC) will be compared with the pullout capacities of cast-in-place and post-installed concrete with drilled holes.
The result of the study showed that the pullout capacity of cast-in-place increased by 64.05% compared to theory, the pullout capacity of the post-installed concrete drill model increased by 68.23% compared to theory, and the pullout capacity of post-installed DBEC increased by 71.51% compared to theory while the pullout capacity of post-installed concrete drill model increased by 11.64% compared to the pullout capacity of cast-in-place and pullout capacity of post-installed DBEC increased by 20.75% compared to pullout capacity of cast-in-place while the pullout capacity of post-installed DBEC increased by 10.3% compared to the pullout capacity of the post-installed concrete drill model. The results of the t-test pullout capacity increased significantly for all variations of anchor hef depth and anchor installation methods.

Development of a Preoperative Psychological Screening Tool: Piloting the Cosmetic Readiness Questionnaire (Pilot-CRQ)
Authors: Pikoos Toni D , Buchanan Ben , Hegarty David , Rossell Susan L 
Published: August 2024

Abstract

Background
Patients with psychological risk factors such as body dysmorphic disorder (BDD) and unmanaged mental health concerns are considered at higher risk for dissatisfaction with aesthetic procedures. Identifying these risks before a procedure may decrease the chance of adverse outcomes for patients and practitioners.

Objectives
In this study we aimed to develop a comprehensive psychological screening tool to assess patient's psychological suitability for surgical and nonsurgical aesthetic procedures.

Methods
Items for the Pilot Cosmetic Readiness Questionnaire (CRQ) were developed by psychologists (n = 3) and then reviewed by plastic surgeons (n = 2) and nonsurgical cosmetic doctors (n = 3). Patient interviews (n = 15) and piloting of the questionnaire (n = 69) provided data regarding the scale's initial psychometric properties.

Results
Results supported the reliability and validity of the Pilot-CRQ's subscales of Body Dysmorphia, Psychological Distress, Self-Criticism, Perfectionism, and Lack of Openness. Lack of Openness was a validity scale that examined the degree that respondents might be underreporting symptoms. The CRQ predicted individuals with a BDD diagnosis, as rated by a blinded expert clinical psychologist, with high sensitivity and specificity.

Conclusions
These results provide support for the Pilot-CRQ identifying people with BDD and psychological factors related to aesthetic treatment outcomes and provide a strong basis for employing the CRQ in clinical contexts and in future research.

Authors: Olaniyi O , Ullah H , Muoka O 
Published: August 2024

Abstract

Aim
To evaluate the management & care outcome of all male patients undergoing bladder outlet obstruction(BOO) intervention by benchmarking against national figures as well as established NICE & EAU guidelines.

Method
A descriptive & retrospective analysis of all patients with BOO, using anonymised unit-level data from patient/operative notes, pre/post-operative clinic letters & investigation portal over 12 months(July 2020 - June 2021).

Results
Of the 77(out of 125) cases that satisfied the inclusion criteria, retention with an in-dwelling catheter was the most prevalent indication for surgery at 45.45%. Overall, perioperative complications such as unsuccessful trial without catheter(TWOC), transfusion, postoperative infection and return to the theatre was 5.19%, with a median length of stay of one day. Comparatively, the failed TWOC rate was 9.09%(&lt; national average of 13.90%) while the post-operative infection rate was 3.89% which was slightly above the national figures. Nonetheless, the unscheduled re-admission rate was 6.49%, fulfilling the 9.60% GIRFT objective. Furthermore, 82.17% of catheterised patients and those performing self-catheterisation before surgery were catheter-free at follow-up. However, 14.20% of preoperatively uncatheterized patients had one at follow-up.

Conclusions
The larger sample size of our re-audit showed the service was comparatively similar to the national norm with minimal unplanned 30-day readmissions, perioperative complications & a large proportion of successful TWOC at follow-up as our initial data suggested. However, while most patients were catheter-free at follow-up, we were slightly below the national average. In addition, it highlighted the need to assess the reason(s) why preoperatively catheter-free patients had one at follow-up.

Authors: Merrison H , Okocha M , Alexander R , Lim J 
Published: August 2024

Abstract

Introduction
A recent tribunal resulted in a doctor being suspended after a dispute regarding an examination. This prompted a review of chaperones in the surgical department for both the safety of the patient and practitioners. According to NICE guidelines chaperones are needed for all intimate examinations and should be considered for all examinations.

Aim
Identify what percentage of surgical clerking’s state:A chaperone was present. (Standard 80%)A chaperone was present during intimate examinations (Per rectum, breast or testicular). (Standard 100%)A chaperone was present during a paediatric consultation. (Standard 100%)

Method
This audit examined the notes of patients seen by the surgical on-call team between 14/12/2022 and 17/12/2022. Information regarding type of examination, age and documentation of a chaperone were collected.

Results
During the study period 81 patients were seen in SAU. Of these 22 received a review by only a junior and 12 received a review by only a registrar. 47 received two reviews. Therefore, this audit examined a total of 128 clerkings. Overall, 4.7% of all examinations had a chaperone documented with no examinations of children documenting a chaperone. 30.8% of intimate examinations had a chaperone documented.

Conclusions
Few chaperones were documented in surgical clerking falling below the standards; however, this may not correlate with chaperone presence. Whilst chaperones may be present, without documentation the practitioner has no protection, should their practice be questioned. Education is necessary to improve chaperone documentation, most urgently paediatric and intimate examinations. A reaudit will be necessary to assess any improvement in documentation.

Authors: Akula Y , Oo A , Ratnaraja N , Menon V 
Published: August 2024

Abstract

Aim
Guideline-adherent antimicrobial usage is associated with a 35% relative risk reduction in mortality and superior post-surgical outcomes. This audit assessed: 1/adherence to local antimicrobial surgical prophylaxis guidelines 2/documentation of antimicrobial indication 3/duration 4/ review outcomes. This was re-audited following teaching sessions to surgical departments.

Method
Data was obtained from drug charts and medical notes of post-surgical inpatients. Data collection periods were: 9/10/23- 20/10/23 (initial audit, 64 patient) and 13/11/23- 17/11/23 (re-audit, 40 patients). Patients were identified from theatre lists for colorectal, hepatobiliary and upper GI surgery. Exclusion criteria included: 1/ age &lt;16 years 2/ long term steroid use or immunocompromised 3/ known colonisation/infection with multidrug resistant organisms. Data was electronically encrypted. Presentation of findings to local surgical and microbiology audit/quality improvement programmes (QIPS) 25/10-7/11/23. Comparison of re-audit findings with the initial audit.

Results
Following the teaching sessions and presentation: Adherence to local antimicrobial prophylaxis improved from 68.8% to 77.5%. Adequate documentation of antimicrobial duration improved from 78.9% to 85.7%. Adequate documentation of antimicrobial review outcome was 20% on initial audit and 22.5% on re-audit. Adequate documentation of indication for antimicrobial regimen increased from 37% to 60%.

Conclusions
Compliance with antimicrobial prophylaxis guidelines, documentation of antimicrobial duration and indication improved. However, documentation of antimicrobial review outcome remained poor. Further collaboration with surgical teams, alongside revision of guidelines for modern surgical practice, is required to improve compliance rate. A further audit is planned to assess for sustained improvement in these outcomes.
325 Cutting Through Assumptions: Assessing Patient Understanding on General Surgical Discharge
Authors: Marsh K , O’Neil A M , Rollo B , Proctor M 
Published: August 2024

Abstract

Aim
Hospital admission can be a stressful and confusing time for patients. There is concern that upon discharge, they may not always be fully aware of their diagnosis, current treatment and proposed follow up, which can in turn negatively affect overall patient experience. This audit aims to quantify patient understanding upon discharge from a busy District General Surgical unit.

Method
Emergency and elective colorectal and UGI general surgical patients (n=98) attending the Victoria Hospital Kirkcaldy (NHS Fife) between November 2022 and April 2023 were included. A handout inspired by, and with permission from, E.N. Thomas et al (1), was created with five key questions assessing patient understanding of elements of their admission including current diagnosis and changes to medicines. These were scored from 1-5 (5 being strongly agree).

Results
Overall the results were positive with most patients scoring highly in all areas. Diagnosis was the highest scoring factor with a mean score of 4.68/5, whilst there was least patient certainty regarding follow up plans scoring 4.37/5. Knowledge surrounding medication changes during admission scored 4.62/5, knowing what problems can occur and who to contact if they do occur, scored 4.58/5 and 4.51/5 respectively.

Conclusions
The findings highlight that patient understanding surpasses levels previously reported, demonstrating that even fast paced surgical ward rounds can provide patients with the correct information. As has been previously suggested, this is a simple cost-effective assessment process that can be used to ensure adequate patient understanding.

Authors: Ang K L , Chen S , Hosten K , Khanna A 
Published: August 2024

Abstract

Aim
Good Surgical Practice document by the Royal College of Surgeons (RCS) England emphasizes the importance of “clear operative notes for every procedure”. Importance of clear documentation is well-established. Accurate and comprehensive documentation facilitates effective handover and aids in medicolegal issues. We assess the current documentation standards for all elective cases in General Surgery between June 2023 – August 2023. We aim to identify and improve compliance of documentation in general surgery operation notes in a district general hospital.

Method
Mandatory operative note domains were taken from Good Surgical Practice (2014) by the RCSEng. Acceptable compliance domains &gt;=90% and poor compliance domains &lt;=50%. We performed a retrospective review of all elective operations performed between June 2023 – August 2023 in the General surgery department.

Results
107 typed operation notes were identified. The department was compliant in the domains of date (94.39%), Operative surgeon (93.46%), procedure (97.20%), operative diagnosis (98.13%), operative finding (91.59%), details of operation (100%), closure technique (96.26%), post-op instructions (99.07%) and signature (100%). We saw poor compliance the domains of elective/emergency procedure (0%), complications/problems (36.45%), additional procedures (0.93%), anticipated blood loss (0.93%), antibiotic prophylaxis (28.04%) VTE prophylaxis (11.21%).

Conclusions
Operation notes are an essential document for post-operative care and effective handover. Appropriate use of the operation note proforma could improve patient care and compliance with RCS guideline.
401 Cardiovascular Risk Factor Optimisation Amongst Inpatients with Peripheral Artery Disease – a Single-Centre Audit
Authors: Kawka M , Camelio M , Farrell–Dillon K , Howie S , Abdelhamid M , Moxey P , Azhar B , Roy I , Budge J 
Published: August 2024

Abstract

Aim
Patients with symptomatic peripheral artery disease (PAD) are highly co-morbid and thus may benefit from cardiovascular disease risk factors optimisation at the time of admission. This audit aimed at reviewing adherence to NICE guidelines for secondary prevention of cardiovascular disease amongst hospital in patients with critical limb-threatening ischaemia (CLTI) or intermittent claudication (IC).

Method
A retrospective review of all CLTI or IC inpatient admissions to a tertiary referral vascular surgery centre, over 9 months, was performed. We assessed adherence to five NICE recommendations for cardiovascular risk factor optimisation: 1) smoking cessation 2) lipid modification 3) antiplatelet therapy 4) blood pressure control 5) diabetes risk assessment, with target adherence of 100%.

Results
97 admissions for PAD were recorded (CLTI n=87, 89.7%; IC n=10, 10.3%). The average age was 70.8±11.7 years, and 68.4% were male. Smoking cessation service was provided to 40.5% of eligible patients, lipid modification to 18.8%, blood pressure control to 29.5%, diabetes risk assessment to 21.1%, and antiplatelet therapy to 38.9%. Admissions longer than 10 days had a significantly higher rate of adherence (&gt;10 days 35.5% vs ≤10 days 19.8%, p=0.017).

Conclusions
There are gaps in risk factor optimisation amongst PAD inpatients, with risk factors either not documented, or addressed appropriately. Shorter, elective hospital admissions were associated with worse risk factor optimisation. A dedicated review of risk factors should be offered to all PAD inpatients early during their admission. To achieve the best long-term adherence, multidisciplinary engagement of geriatrics, smoking cessation, diabetes, and primary care is essential.
402 An Insight into the Use of Tourniquet During Orthopaedic Surgery at a District General Hospital
Authors: Khan M A , Rddah M , Gaukroger A , Ashby L , Logan J 
Published: August 2024

Abstract

Introduction
Tourniquet is a device used by orthopaedic surgeons to produce a bloodless field for limb operations. Historically applied to the most proximal part of the limb.  The British Orthopaedic Association (BOA) created guidelines for the use of intraoperative tourniquet in October 2021.

Method
A retrospective study of the elective and emergency operation notes utilising tourniquet was performed over one month. The results were presented at the departmental educational meeting. A new operation note template was employed. A further month period was retrospectively reviewed.

Results
Over one month, 72 operations were carried out where a tourniquet was used, of them 45.8% (n=33) were on the upper limb (UL) compared to 54.2% (n=39) on the lower limb (LL). The inflation pressure was incorrectly used in 72.7% (n=24) of UL operations and 43.5% (n=17) of LL operations. The type and size of tourniquet was not recorded in 68.05% (n=49) and 41.7% respectively.
A further one-month period was appraised post changed applied.
Tourniquet was used in 34 operations with 54.2%(n=15) on the UL and 55.8% (n=19) on the LL. The inflation pressure was incorrectly applied in 30% of UL operations in comparison to 72.7% previously. The LL tourniquet pressure was incorrect in 22% of operations compared to 43.5% beforehand. The type and size of tourniquet used was recorded in 71% and 60% respectively. The skin condition prior to tourniquet was recorded in 40% of operations.

Conclusions
The implementation of an electronic operation note has improved our hospital’s compliance with national standards on safe tourniquet use.
413 Standardised Informed Consent for Right Hemicolectomies
Authors: Mann L , Peacock M 
Published: August 2024

Abstract

Aim
Consent is vital to enable patients to make informed decisions in regard to their treatment. Our audit reviewed the risks patients undergoing a right hemicolectomy consented for, with the aim of introducing a standardised consent form sticker.

Method
A retrospective analysis of all patients undergoing a right hemicolectomy was undertaken over a 1-year period at a district general hospital. Clinical notes were reviewed to compare consent forms regarding the indication for operation, risks and complications consented for, along with actual outcomes. Patients were excluded if additional operations were performed or if a consent form 1 was not used.

Results
25 patients were included with an average age of 71 years. The forms were completed by a Consultant in 40% of cases, the remaining being completed by a registrar. 2 consent forms were illegible. Risks consented for were inconsistent between patients. Interestingly, 40% of patients suffered from a post-operative complication, not all of which were consented for.

Conclusions
This project demonstrates variation within our consent process. We have proposed a pre-printed right hemicolectomy consent form sticker listing complications as agreed by the consultant body for our speciality. This has been presented at our departmental governance meeting and alterations have been made in response to feedback. We will complete the audit cycle and plan to extend this initiative to all colorectal procedures at our hospitals. An exciting innovation may involve digital consent forms via text or email whenever appropriate.
