Improving theatre turnaround time

A Survey of the Estimated Cost of Surgical Consumable Items Within Trauma and Orthopaedic Departments

Introduction The impact of the current economic and environmental climate, both nationally and globally, is further straining the NHS. This has led to scrutiny of high-expenditure areas, including consumables. Clinician's knowledge surrounding health economics is sparse, and we conducted this survey to assess cost-awareness within the Trauma and Orthopaedic (T&O) departmental staff. Methods A questionnaire was digitally distributed to T&O staff in the East Kent Hospitals Trust. This included demographic data and to make estimations of the cost of 10 specialty-specific items. The data were analysed to determine the average, median, and interquartile range (IQR) of the estimated prices and compared to the actual costs. Results Approximately 7.1% of all item estimates were deemed 'correct'. No correlation was seen between years of staff experience and the accuracy of estimates. 'Kenalog 1 mL ampoule' (Kenalog, Bristol-Myers Squibb, NJ) had the highest accuracy of estimation across all responses (13%), whilst both 'kirschner wires' and '3.2 drill bit' had the lowest accuracy (4% each). The median estimated cost was closest to the actual cost for 'cement pack' (median estimate/actual cost = 0.9). The median estimated cost was furthest from the actual cost for 'tourniquet cuffs' (median estimate/actual cost = 0.16). 'Velcro wrist splint' was the item that was the most overestimated (median estimate/actual cost = 1.57), with only two of the 10 items being overestimated ('velcro wrist splint' and 'dynamic hip screw and plate'). The most underestimated item was 'tourniquet cuffs' (median estimate/actual cost = 0.16). Conclusions There is a paucity of knowledge surrounding the cost of specialist T&O consumables. The limitations included the sample size (98 respondents) and geographical area (East Kent Hospitals Trust). This study shows that there is a need for further research into this topic, with long-term outcomes, which may be beneficial both economically and environmentally.

Creating Novel Standards for Datapoints on an Elective Orthopaedic Theatre List Document

Introduction

Orthopaedic theatre lists are an important tool which must convey essential information to all staff to run an effective and safe theatre list. However, there are no set standards or guidelines on the components of an Orthopaedic theatre list. The objective of this study is to formulate guidelines for elective Orthopaedic theatre lists which improve efficiency and reduce errors.

Materials and Methods

We looked at 326 elective Orthopaedic theatre lists from October to November 2018. Various factors such as: theatre and patient demographics, surgical team, type of anaesthesia, Surgery, acronyms and finally extra information such as allergies. Additionally, a survey was distributed to a variety of theatre staff to understand their requirements from a theatre list. Thereafter, we created a proforma for waiting list coordinators. Subsequently, we re-audited six more weeks of theatre lists (255) from November to December 2019.

Results

The orthopaedic consultant in charge was noted for 100% of patients compared to 85% previously. There was an improvement in documenting the required anaesthesia such as noting 14.5% required spinal compared to 0.3% previously. Prosthesis/equipment was mentioned for 34% of patients compared to 23%. Fluoroscopy was noted as being required for 25% of patients compared to 11%.

Conclusion

We believe standards should be in place in order for us to follow to ensure we carry out safe and efficient Orthopaedic theatre lists, and these standards should entail the parameters we have audited. The 'William Harvey theatre list standard' should be used as a gold standard for all elective Orthopaedic theatre lists.

Time is a terrible thing to waste: optimising use of intraoperative monitoring practitioner time towards maximising in-house IOM service provision and reducing spend on external provision

Intraoperative monitoring (IOM) during orthopaedic and neurosurgical operations informs surgeons about the integrity of patients' central and peripheral nervous systems. It is provided by IOM practitioners (IOMPs), who are usually neurophysiology healthcare scientists. Increasing awareness of the benefits for patient safety and surgical outcomes, along with post-COVID-19 service recovery, has resulted in a material increase in demand for IOM provision nationally, and particularly at Salford Royal Hospital (SRH), which is a regional specialist neurosciences centre.There is a shortage of IOMPs in the UK National Health Service (NHS). At SRH, this is exacerbated by staff capacity shortage, requiring £202 800 of supplementary private provision in 2022.At SRH, IOMPs work in pairs. Our productive time is wasted by delays to surgical starts beyond our control and by paired working for much of a surgery session. This quality improvement (QI) project set out to release productive time by: calling the second IOMP to theatre only shortly before start time, the other IOMP returning to the office during significant delays, releasing an IOMP from theatre when appropriate and providing a laptop in theatre for other work.We tested and refined these change ideas over two plan-do-study-act improvement cycles. Compared with complete paired working, we increased the time available for additional productive work and breaks from an average of 102 to 314 min per operating day, not quite achieving our project target of 360 min.The new ways of working we developed are a step towards ability (when staff capacity increases) to test supporting two (simultaneous) operations with three IOMPs (rather than two pairs of IOMPs). Having significantly improved the use of staff time, we then also used our QI project data to make a successful business case for investment in two further IOMP posts with a predicted net saving of £20 000 per year along with other associated benefits.

Why can't we improve turnover time? A systematic review

BACKGROUND

Despite substantial efforts to reduce operating room (OR) turnover time (TOT), delays remain a frustration to physicians, staff, and hospital leadership. These efforts have employed many systems and human factor-based approaches with variable results. A deeper dive into methodologies and their applicability could lead to successful and sustained change. The aim of this study was to conduct a systematic review to evaluate relevant research focused on improving OR TOT and clearly defining measures of successful intervention.

MATERIAL AND METHODS

A systematic review of OR TOT interventions implemented between 1980 through October 2022 was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. Research databases included: 1) PubMed; 2) Web of Science; and 3) OVID Medline.

RESULTS

A total of 38 articles were appropriate for analysis. Most employed a pre/post intervention approach (29, 76.3%), the remaining utilized a control/intervention approach. Nine intervention methods were identified: the majority included a process redesign bundle (24, 63%), followed by overlapping induction, dedicated unit/team/space feedback, financial incentives, team training, education, practice guidelines, and redefinition of roles/responsibilities. Studies were further categorized into one of two groups: (1) those that utilized predetermined interventions based on anecdotal experience or prior literature (18, 47.4%) and (2) those that conducted a prospective analysis on baseline data to inform intervention development (20, 52.6%).

DISCUSSION

There are significant variability in the methodologies utilized to improve OR TOT; however, the most effective solutions involved process redesign bundles developed from a prospective investigation of the clinical work-system.

Introduction of a New Protocol to Limit the Number of Cancelled Elective Orthopaedic Operations Due to Asymptomatic Bacteriuria

Background Asymptomatic bacteriuria (ASB) poses a significant diagnostic dilemma for medical professionals. Current hospital screening protocol determines the likelihood of a positive diagnosis of a urinary tract infection (UTI) based on the results of a bedside urinalysis. ASB, defined as a positive urine culture in the absence of symptoms, can contribute to unnecessary cancellations, poor utilisation of theatre time, and delayed patient care. We present a two-cycle audit proposing a new pathway to addressing ASB in patients awaiting elective orthopaedic surgery, aiming to optimise surgical yield. Our objectives are to identify areas for improvement in our departmental practices with respect to asymptomatic bacteria compared to the published literature. We propose a new protocol targeted to improve our current practices to minimise patient cancellations and optimise theatre utilisation. Methodology A total of 78 patients who had an elective orthopaedic procedure cancelled at a large district general hospital offering tertiary orthopaedic services, between two study periods spanning March 2018 to April 2019 and May 2019 to March 2020, were identified from electronic hospital records and theatre management systems. Demographics, procedure details, and reasons for cancellations, including the result of urinalysis and the presence of UTI symptoms were assessed. Our pathway was introduced after the first study period and, subsequently, re-audited to assess adherence to the new protocol and its effect on cancellations. Results We identified 78 patients, with a 50:50 male:female split and an average age of 63 (range = 9-90). Of the 33 patients in the first cohort, seven (21.2%) were cancelled due to UTI risk based on positive urinalysis. Of these seven cancellations, one (14.3%) patient reported symptoms of a UTI. The second cohort comprised 45 patients, two (4.4%) of whom were cancelled due to UTI risk based on symptom questionnaire results. These two symptomatic patients along with another two asymptomatic patients (8.8% in total) were found to have positive urinalyses; however, the two asymptomatic patients had their operations cancelled for unrelated reasons. Conclusions The study has shown that previously of all patients awaiting elective orthopaedic operations who had their procedures cancelled, 85.7% were cancelled due to ASB. After the introduction of a new protocol focussing on symptoms rather than urinalysis, we estimate that the number of cancelled elective orthopaedic operations has reduced by 71.4%, thereby greatly improving the utilisation of theatre time.

The perioperative utility of 3D printed models in complex surgical care: feedback from 106 cases

INTRODUCTION

3D models are an emerging tool for surgical planning, providing an augmented method for the visualisation of a patient's anatomy. As their use increases, more data about the utility of these models is critical to inform budget allocation. This study provides the most comprehensive analysis to date for the use of 3D models in perioperative management.

METHODS

3D models for complex surgical cases in NHS hospitals were delivered alongside a surgeon feedback survey. The survey on the model's utility had been designed alongside the university data analytical team and focused on five areas: surgical planning and diagnosis, economic impact, impact on intraoperative and preoperative time, effect on communication and direct impact on the patient.

RESULTS

There were 106 models used by 63 surgeons for complex surgical cases between May 2020 and March 2021, across multiple surgical specialties. The models were reported to have benefits in all perioperative areas, with 92.5% of responses agreeing that the 3D model was a better method for diagnosis and planning than traditional 2D techniques. Benefits were reported on preoperative planning (92.4%), economic savings due to equipment selection (54.4%), reduction in surgical time (41.5%) and surgeon-to-surgeon communication (92.6%).

CONCLUSION

3D models were shown to have a wide range of benefits in a surgical setting. The reduction in surgical time could have the potential to help alleviate surgical backlogs. With more widespread use and optimisation of costs the use of 3D models could become the standard for unusual and complex surgical cases.

Twelve tips for optimising learning for postgraduate doctors in the operating theatre

Learning in the operating theatre forms a critical part of postgraduate medical education. Postgraduate doctors present a diverse cohort of learners with a wide range of learning needs that will vary by their level of experience and curriculum requirements. With evidence of both trainee dissatisfaction with the theatre learning experience and reduced time spent in the operating theatre, which has been exacerbated by the effects of the Covid-19 pandemic, it is vital that every visit to the operating theatre is used as a learning opportunity. We have devised 12 tips aimed at both learners and surgeons to optimise learning in the operating theatre, set out into four domains: educational context, preparation, learning in theatre, feedback and reflection. These tips have been created by a process of literature review and acknowledgment of established learning theory, with further discussion amongst surgical trainees, senior surgical faculty, surgical educators and medical education faculty.

Early Management of Paediatric Wrist and Forearm Fractures in a Busy District General Hospital Emergency Department: A Retrospective Cohort Comparison Study and Audit of BOAST Guidelines

INTRODUCTION

In response to the strain that the COVID-19 pandemic put on hospitals in the UK, the British Orthopaedic Association, in May 2021, set out British Orthopaedic Association Standards for Trauma and Orthopaedics (BOAST) guidelines for the early management of distal forearm fractures in children. Following this, a local pathway was introduced at our Trust to manage these injuries in the Emergency Department (ED). The aim of this audit was to monitor compliance with the BOAST guidelines and compare the practice with a similar pre-COVID cohort.

METHODS

A fixed-date retrospective cohort study was conducted that included cases that presented to the emergency department during a six-month period (August 1, 2021 to January 31, 2022). Data was analysed for rates of primary ED manipulation, documentation of consent and neurovascular status in the notes, orthogonal X-ray data, time till the clinic follow-up, theatre time saved and complications. The ED fracture manipulation rate was also compared with another similar pre-COVID cohort (August 1, 2019 to January 31, 2020) to look for any improvement in the practice.

RESULTS

A total of 86.31% cases were found to have primary fracture manipulation in the ED following the introduction of Trust guidelines in accordance with the BOAST recommendations. This is an improvement in comparison to the 31.94% fracture manipulation rate before the COVID pandemic.

CONCLUSION

Implementation of the Trust pathway in accordance with the BOAST guidelines along with staff education has standardized the practice at our Trust. It saved approximately 63 hours of trauma theatre time for the six-month data collection period. Our findings also suggest that this has favourable outcomes for the patients with no complications.

The Impact of Tourniquet Usage on TKA Outcome: A Single-Center Prospective Trial

Background and Objectives: Total knee arthroplasties (TKAs) are the most effective surgical treatment for end-stage knee osteoarthritis. The tourniquet is used to reduce intraoperative blood loss, improving surgical field visualization. There is much controversy regarding the effectiveness and safety of using a tourniquet during total knee arthroplasties. The purpose of this prospective study is to determine the effect of tourniquet usage during TKAs on early functional outcomes and pain in our center. Materials and Methods: We conducted a randomized controlled trial of patients following a primary total knee replacement between October 2020 and August 2021. We recorded presurgical data, which included age, sex and knee range of motion. Intraoperatively, we measured the amount of blood aspiration and the surgical room time. After the surgery, we measured the amount of blood aspirated through the drains and the hemoglobin. We measured flexion, extension, Visual Analogue Scale (VAS) scores, and Western Ontario and McMaster Universities Arthritis Index (WOMAC score) scores for the functional evaluation. Results: We included 96 patients in the T group and 94 in the NT group, respectively, who remained until the last follow-up. Regarding blood loss, the NT group demonstrated significantly lower levels: 245 ± 97.8 mL intraoperative and 324.8 ± 151.65 mL postoperative, compared to the T group, where we recorded 276 ± 109.2 mL during the surgical procedures and 353.44 ± 101.55 mL after the surgery, (p < 0.05). We also recorded significantly shorter operative room time for the NT group, (p < 0.05). During the follow-up, we noticed postoperative improvements but without significant differences between the groups. Conclusions: We found a significant decrease in bleeding after no tourniquet usage during total knee replacements and shorter operative times. On the other hand, the knee function demonstrated no significant differences between the groups. Further studies may be required in order to assess complications.

Systematic review and meta-analysis comparing perioperative outcomes of emergency appendectomy performed by trainee vs trained surgeon

BACKGROUND

Appendectomy is a benchmark operation for trainee progression, but this should be weighed against patient safety and perioperative outcomes.

METHODS

Systematic literature review and meta-analysis comparing outcomes of appendectomy performed by trainees versus trained surgeons.

RESULTS

Of 2086 articles screened, 29 studies reporting on 135,358 participants were analyzed. There was no difference in mortality (Odds ratio [OR] 1.08, P = 0.830), overall complications (OR 0.93, P = 0.51), or major complications (OR 0.56, P = 0.16). There was no difference in conversion from laparoscopic to open surgery (OR 0.81, P = 0.12) and in intraoperative blood loss (Mean Difference [MD] 5.58 mL, P = 0.25). Trainees had longer operating time (MD 7.61 min, P < 0.0001). Appendectomy by trainees resulted in shorter duration of hospital stay (MD 0.16 days, P = 0.005) and decreased reoperation rate (OR 0.78, P = 0.05).

CONCLUSIONS

Appendectomy performed by trainees does not compromise patient safety. Due to statistical heterogeneity, further randomized controlled trials, with standardized reported outcomes, are required.

A Perspective on Theatre Efficiency in Terms of Theatre Utilisation and Theatre Costs and the Effects of Infection Control Protocols on These During the COVID-19 Pandemic

Background and aim The coronavirus disease 2019 (COVID-19) pandemic has had a significant impact on healthcare systems. Several local infection control methods were put in place, which have now evolved and continued in some form or the other. According to various research, as the time duration for distinct phases in the pathway rose, trauma theatre efficiency reduced. However, there is no literature, to our knowledge, that has explicitly looked at theatre utilisation and cost efficiency compared them and expressed theatre efficiency in these terms. The aim of this article is to study theatre efficiency in terms of utilisation and costs before and during the pandemic and understand the influence of infection control protocols on these. Materials and methods The data were collected retrospectively from the ORMIS theatre management software (iPath Softwares, Ohio), from December 2019 (pre-COVID) and December 2020 (COVID). Turnaround time, utilisation time and combined operative time were defined and compared. Costs incurred due to over-running, under-running and turnaround time were compared. Results Theatre utilization was 101% during COVID and 86.63% pre-COVID. The average cost of over-running as well as under-running a theatre list during the pandemic was significantly higher. Conclusion Optimal theatre utilisation and reduced time between cases improve theatre efficiency. Turnaround time, if reduced, can not only decrease costs but also increase efficiency.Theatre utilisation and efficiency can be maintained even with new infection control protocols, but these are not cost-efficient.

Influence of COVID-19 Protocols on the Efficiency of Trauma Theater: Retrospective Observational Study

BACKGROUND

The COVID-19 pandemic has influenced health care delivery significantly. Numerous studies have highlighted that trauma theater efficiency has decreased during the COVID-19 pandemic; however, there is limited information as to exactly which stage of the patient theater journey is causing this decreased efficiency and whether efficiency can be improved. In the trauma theater of Warrington Hospital, United Kingdom, we have attempted to maintain trauma theater efficiency despite the requirement for increased infection control.

OBJECTIVE

The aim of this study was to evaluate the effects of additional COVID-19 infection control protocols on trauma theater efficiency in our center, considering the length of time taken for specific theater events, and to find out whether our interventions were successful in maintaining theater efficiency.

METHODS

We compared the efficiency of the trauma theater in a busy unit in December 2019 (pre-COVID-19) and December 2020 (with COVID-19 protocols in place). We collected time logs for different theater events for each patient in December of both years and compared the data.

RESULTS

There was no significant difference in the average number of cases performed per session between the COVID-19 and pre-COVID-19 time periods (P=.17). Theater start time was significantly earlier during the COVID-19 period (P<.001). There was no significant difference between the two periods in transport time, check-in time, preprocedure time, anesthetic time, and the time between cases (P>.05). A significant difference was observed in the check-out time between the two groups in the two time periods, with checking out taking longer during the COVID-19 period (P<.001).

CONCLUSIONS

Our results show that our theater start times were earlier during the COVID-19 pandemic, and the overall theater efficiency was maintained despite the additional COVID-19 infection control protocols that were in place. These findings suggest that well-planned infection control protocols do not need to impede trauma theater efficiency in certain settings.

Rectal Foreign Bodies: Surgical Management and the Impact of Psychiatric Illness

Background

Entrapped rectal foreign bodies can be a challenge to manage and are being encountered by acute surgical teams with increasing frequency. The aims of our study were to (a) ascertain the population demographics of patients presenting with this problem in our local area of East Kent, (b) see if an association could be drawn between this presentation and proposed risk factors such as a psychiatric illness or socioeconomic deprivation, and (c) to review how foreign bodies are being removed in the East Kent Hospital University Foundation NHS Trust, United Kingdom and to highlight best practice with regards to this in line with the latest guidelines.

Methodology

Between 2017 and 2021, 32 cases of entrapped rectal foreign bodies were diagnosed and managed at our NHS Trust. Retrospective data taken from the theatre directory and electronic patient records were used to audit patient demographics, co-morbidities, the type of foreign body, and the extraction technique.

Results

The majority of patients (90%) were male (n = 29). The patients’ age ranged from 15 to 95 years, with a median age of 48 years. In total, 12 (37.5%) patients had a medical history of a psychiatric illness. The most common foreign bodies removed were sex toys or vibrators (n = 8) and roll-on deodorant bottles (n = 7). Kent Area B (n = 10) and Kent Area A (n = 9) were the areas with the highest number of cases. Twenty-two (68.8%) patients underwent examination under a general anaesthetic for removal, seven (21.8%) patients had the object manually removed without sedation, and three (9.4%) required a laparotomy with or without bowel resection.

Conclusions

Cases of an entrapped rectal foreign body in this local region typically involved male patients between 40 and 50 years old. A high proportion of this group had a history of a psychiatric illness supporting an association between this presentation and mental health. We have proposed some explanations for this association including the anal canal nervous system interplay with the “brain-gut axis.” Lower socioeconomic status and unemployment may also be risk factors for this surgical problem. A trans-anal approach for management is successful in the majority of cases; however, almost 10% of patients required emergency surgical management. We have highlighted best practice guidelines for the investigation and management of the entrapped rectal foreign body as part of our discussion.

The Effect of the COVID-19 Pandemic on Theatre Efficiency, Lessons to be Learned for Subsequent Waves

BACKGROUND

This study aims to demonstrate the impact of the COVID-19 pandemic on providing trauma services at our district general hospital. We aim to identify the impact on specific areas of theatre delay to help optimize theatre efficiency and generate better protocols and improve patient flow for future pandemic waves.

METHODS

Patients who underwent orthopaedic trauma surgery at our hospital between July-August 2019 (pre-COVID-19) and 2020 (first UK wave of COVID-19) were identified retrospectively and grouped by year of operation. Type of operation was recorded, including time for sending, anaesthetic induction, surgical preparation, operating time, and time for transfer to recovery. The two groups were compared for analysis.

RESULTS

Case numbers were similar in both 2019 and 2020 (215vs.213 operations), with a similar proportion being hip fractures (39.1% and 36.6%), respectively. Median sending time (40vs.23 minutes, P <0.00001) and induction time (13vs.8 minutes, P<0.00001) were increased in 2020, a 74% and 63% increase compared to 2019, respectively. Median surgical preparation time (35vs.37 minutes, P=0.06) and operating time (56vs.50 minutes, P=0.16) were not statistically significant. Transfer time in 2020 (16vs.13 minutes, P<0.00001) was significantly increased. Overall case time increased in 2020 (2:40vs.2:11, P<0.00001) by 29 minutes.

CONCLUSION

COVID-19 had a significant impact on theatre efficiency in our hospital, causing multiple points of delay. As hospitals across the UK restart crucial elective services, focus should be given to maximizing theatre efficiency by providing rapid access COVID-19 testing for patients undergoing emergency surgery. We have proposed and implemented several steps for better theatre utilization.

Operation Note Transformation: The Application of Lean Six Sigma to Improve the Process of Documenting the Operation Note in a Private Hospital Setting

Clinical documentation is a key safety and quality risk, particularly at transitions of care where there is a higher risk of information being miscommunicated or lost. A surgical operation note (ON) is an essential medicolegal document to ensure continuity of patient care between the surgical operating team and other colleagues, which should be completed immediately following surgery. Incomplete operating surgeon documentation of the ON, in a legible and timely manner, impacts the quality of information available to nurses to deliver post-operative care. In the project site, a private hospital in Dublin, Ireland, the accuracy of completion of the ON across all surgical specialties was 20%. This project sought to improve the accuracy, legibility, and completeness of the ON in the Operating Room. A multidisciplinary team of staff utilised the Lean Six Sigma (LSS) methodology, specifically the Define/Measure/Analyse/Design/Verify (DMADV) framework, to design a new digital process application for documenting the ON. Post-introduction of the new design, 100% of the ONs were completed digitally with a corresponding cost saving of EUR 10,000 annually. The time to complete the ON was reduced by 30% due to the designed digital platform and mandatory fields, ensuring 100% of the document is legible. As a result, this project significantly improved the quality and timely production of the ON within a digital solution. The success of the newly designed ON process demonstrates the effectiveness of the DMADV in establishing a co-designed, value-adding process for post-operative surgical notes.

Minimally Invasive Sacroiliac Joint Fusion with Triangular Titanium Implants: Cost-Utility Analysis from NHS Perspective

OBJECTIVE

The aim was to identify the cost-effectiveness of minimally invasive sacroiliac joint fusion (MI SIJF) surgery with titanium triangular implants for patients with sacroiliac joint (SIJ) pain who have failed conservative management, compared to non-surgical management (NSM) from a National Health Service (NHS) England perspective.

METHODS

Over a time horizon of 5 years, a cohort state transition model compared the costs and outcomes of treating patients with MI SIJF to those of traditional NSM treatment pathways. The NSM arm included two treatments: grouped physical therapy and corticosteroid injections (PTSI) or radiofrequency ablation (RFA). Three different strategies were considered: (1) a stepped pathway, (2) patients split between PTSI and RFA, and (3) RFA only. The outcome measure was incremental cost-effectiveness ratio (ICER), reported in 2018 British pounds per quality-adjusted life year (QALY) gained. One-way and probabilistic sensitivity analyses were used to test the robustness of the model results.

RESULTS

Patients undergoing MI SIJF accrued total procedure-related and pain-management costs of £8358, while NSM treatment strategy 1 had total costs of £6880. The MI SIJF cohort had 2.98 QALYs compared to strategy 1 with 2.30 QALYs. This resulted in an ICER for MI SIJF versus strategy 1 of £2164/QALY gained. Strategy 2 of the NSM arm had lower costs than strategy 1 (£6564) and 2.26 QALYs, and this resulted in an ICER of £2468/QALY gained for MI SIJF. Strategy 3 of the NSM arm had lower costs than strategy 1 (£6580), and this resulted in 2.28 QALYs and an ICER of £2518/QALY gained for MI SIJF. Probabilistic sensitivity analysis shows that at a threshold of £20,000/QALY gained, MI SIJF has a probability of being cost-effective versus NSM strategies of 96%, 97%, and 91% for strategies 1, 2, and 3, respectively.

CONCLUSION

MI SIJF appears to be cost-effective over a 5-year time horizon when compared to traditional NSM pathways in an NHS context.

WALANT Hand and Upper Extremity Procedures Performed With Minor Field Sterility Are Associated With Low Infection Rates

Background:

The use of minor field sterility in hand/upper extremity cases has been shown to improve workflow efficiency while maintaining patient safety. As this finding has been limited to specific procedures, we investigated the safety of performing a wide array of hand/upper extremity procedures outside the main operating room using minimal field sterility with Wide-Awake Local Anaesthesia No Tourniquet (WALANT) anaesthesia by evaluating superficial and deep infection rates across a diverse series of cases.

Methods:

This study was a case series conducted between October 2017 and June 2020. Of all, 217 patients underwent hand/upper extremity procedures performed in a minor procedure room via WALANT technique with field sterility. Primary outcome measures include superficial and deep surgical site infections within 14 days post-surgery.

Results:

Of all, 217 patients were included in this study; 265 consecutive hand/upper extremity operations were performed by a single surgeon, with notable case diversity. The majority of patients (n = 215, 99.1%) did not report or present with signs of infection before or after their operation. We report 0% 14-day and 0.37% 30-day surgical site infection rates for such hand/upper extremity procedures performed in a minor procedure room with field sterility.

Conclusion:

Hand/upper extremity procedures performed via WALANT technique with field sterility in a minor procedure room are associated with low surgical site infection rates. These rates are comparable to surgical site infection rates for similar surgeries performed in main operating rooms with standard sterilization procedures. Thus, the implementation of this technique may allow for improved workflow efficiency and reduced waste, all while maintaining patient safety.

Opportunities and challenges of using augmented reality and heads-up display in orthopaedic surgery: A narrative review

BACKGROUND & AIM

Utilization of augmented reality (AR) and heads-up displays (HUD) to aid orthopaedic surgery has the potential to benefit surgeons and patients alike through improved accuracy, safety, and educational benefits. With the COVID-19 pandemic, the opportunity for adoption of novel technology is more relevant. The aims are to assess the technology available, to understand the current evidence regarding the benefit and to consider challenges to implementation in clinical practice.

METHODS & RESULTS

PRISMA guidelines were used to filter the literature. Of 1004 articles returned the following exclusion criteria were applied: 1) reviews/commentaries 2) unrelated to orthopaedic surgery 3) use of other AR wearables beyond visual aids leaving 42 papers for review.This review illustrates benefits including enhanced accuracy and reduced time of surgery, reduced radiation exposure and educational benefits.

CONCLUSION

Whilst there are obstacles to overcome, there are already reports of technology being used. As with all novel technologies, a greater understanding of the learning curve is crucial, in addition to shielding our patients from this learning curve. Improvements in usability and implementing surgeons' specific needs should increase uptake.

Time to reconsider the routine use of tourniquets in total knee arthroplasty surgery

Aims

Many surgeons choose to perform total knee arthroplasty (TKA) surgery with the aid of a tourniquet. A tourniquet is a device that fits around the leg and restricts blood flow to the limb. There is a need to understand whether tourniquets are safe, and if they benefit, or harm, patients. The aim of this study was to determine the benefits and harms of tourniquet use in TKA surgery.

Methods

We searched MEDLINE, EMBASE, Cochrane Central Register of Controlled trials, and trial registries up to 26 March 2020. We included randomized controlled trials (RCTs), comparing TKA with a tourniquet versus without a tourniquet. Outcomes included: pain, function, serious adverse events (SAEs), blood loss, implant stability, duration of surgery, and length of hospital stay.

Results

We included 41 RCTs with 2,819 participants. SAEs were significantly more common in the tourniquet group (53/901 vs 26/898, tourniquet vs no tourniquet respectively) (risk ratio 1.73 (95% confidence interval (CI) 1.10 to 2.73). The mean pain score on the first postoperative day was 1.25 points higher (95% CI 0.32 to 2.19) in the tourniquet group. Overall blood loss did not differ between groups (mean difference 8.61 ml; 95% CI -83.76 to 100.97). The mean length of hospital stay was 0.34 days longer in the group that had surgery with a tourniquet (95% CI 0.03 to 0.64) and the mean duration of surgery was 3.7 minutes shorter (95% CI -5.53 to -1.87).

Conclusion

TKA with a tourniquet is associated with an increased risk of SAEs, pain, and a marginally longer hospital stay. The only finding in favour of tourniquet use was a shorter time in theatre. The results make it difficult to justify the routine use of a tourniquet in TKA surgery.

Acellular dermal matrix reconstruction of a nail bed avulsion in a 13-year-old child

Nail bed avulsion injuries often require reconstruction, particularly in cases where the avulsed fragment is lost. We describe a simple way to reconstruct a large nail bed defect, with no donor site. A 13-year-old boy with a hypoplastic left heart and autism accidentally sustained a left little distal phalanx injury with an avulsion of 60% of the nail bed, exposing the distal phalanx. This boy had a history of poor compliance, qualifying the need to find a technique that would minimise operative time and dressing changes. As such, it was elected to use an acellular dermal matrix (ADM) (Matriderm) as a one-step reconstruction. Signs of vascularisation of the ADM were noted at 2 weeks, and 3-month follow-up demonstrated integration, with normal nail growth. We found that Matriderm was able to support the regeneration of a full thickness wound in a simple one-step procedure.

Determinants of lost theatre capacity

Secondary care Trusts nationwide are continuing to fail the 18-week referral to treatment (RTT) target despite several initiatives to improve theatre efficiency (2018 NHS England review). A limitation of wasted theatre productivity is required to alleviate pressures on waiting lists. Productivity, which is a measure of treatment time as a proportion of available/allocated time, takes into consideration variations in operator performance, early (non-funded) theatre starts, and over-run, and its analysis enables the determination of theatre downtime and lost theatre capacity. We monitored productivity over a 12-week period and performed downtime analysis as reported in the NHS Improvement national audit (NHSI). Results showed a marked but predictable variation in productivity connected to turnaround and session list scheduling. Productivity and booking efficiency correlated uniformly (Pearson's r=0.82). Theatre downtime was analysed with respect to three components defined in the NHSI national audit: late starts, early finish, and turnaround. We found that lost theatre time was predominantly due to early finishes; late starts were infrequent. Transport time correlated unfavourably with productivity (Pearson's r=-0.29, p=0.037) and over-run (r=0.44), and prolonged transport times were shorter when surgery was performed in a dedicated day surgery unit. Calculating the mean transport times for lists with high compared with low productivity helped us set a benchmark for patient transport times for future audit.

The effect of COVID-19 on the trauma burden, theatre efficiency and training opportunities in a district general hospital: planning for a future outbreak

Aims

The aim of this study is to determine the effects of the UK lockdown during the COVID-19 pandemic on the orthopaedic admissions, operations, training opportunities, and theatre efficiency in a large district general hospital.

Methods

The number of patients referred to the orthopaedic team between 1 April 2020 and 30 April 2020 were collected. Other data collected included patient demographics, number of admissions, number and type of operations performed, and seniority of primary surgeon. Theatre time was collected consisting of anaesthetic time, surgical time, time to leave theatre, and turnaround time. Data were compared to the same period in 2019.

Results

There was a significant increase in median age of admitted patients during lockdown (70.5 (interquartile range (IQR) 46.25 to 84) vs 57 (IQR 27 to 79.75); p = 0.017) with a 26% decrease in referrals from 303 to 224 patients and 37% decrease in admissions from 177 to 112 patients, with a significantly higher proportion of hip fracture admissions (33% (n = 37) vs 19% (n = 34); p = 0.011). Paediatric admissions decreased by 72% from 32 to nine patients making up 8% of admissions during lockdown compared to 18.1% the preceding year (p = 0.002) with 66.7% reduction in paediatric operations, from 18 to 6. There was a significant increase in median turnaround time (13 minutes (IQR 12 to 33) vs 60 minutes (IQR 41 to 71); p < 0.001) although there was no significant difference in the anaesthetic time or surgical time. There was a 38% (61 vs 38) decrease in trainee-led operations.

Discussion

The lockdown resulted in large decreases in referrals and admissions. Despite this, hip fracture admissions were unaffected and should remain a priority for trauma service planning in future lockdowns. As plans to resume normal elective and trauma services begin, hospitals should focus on minimising theatre turnaround time to maximize theatre efficiency while prioritizing training opportunities.

Assessing the Impact of Lean Healthcare on Inpatient Care: A Systematic Review

Healthcare services are facing challenges in increasing their efficiency, quality of care, and coping with surges in demand. To this end, some hospitals have implemented lean healthcare. The aim of this systematic review is to evaluate the effects of lean healthcare (LH) interventions on inpatient care and determine whether patient flow and efficiency outcomes improve. The review was performed according to PRISMA. We used six databases to search for studies published from 2002 to 2019. Out of 5732 studies, 39 measuring one or more defined outcomes were included. Hospital length of stay (LOS) was measured in 23 studies, 16 of which reported a reduction, turnover time (TOT) decreased in six out of eight studies, while the turnaround time (TAT) and on-time starts (OTS) improved in all five and seven studies, respectively. Moreover, eight out of nine studies reported an earlier discharge time, and the boarding time decreased in all four cases. Meanwhile, the readmission rate did not increase in all nine studies. Lastly, staff and patient satisfaction improved in all eight studies. Our findings show that by focusing on reducing non-value-added activities, LH contributed to improving patient flow and efficiency within inpatient care.

Ticagrelor Removal by CytoSorb® in Patients Requiring Emergent or Urgent Cardiac Surgery: A UK-Based Cost-Utility Analysis

BACKGROUND

Acute coronary syndrome patients receiving dual antiplatelet therapy who need emergent or urgent cardiac surgery are at high risk of major bleeding, which can impair postoperative outcomes. CytoSorb^®, a blood purification technology based on adsorbent polymer, has been demonstrated to remove ticagrelor from blood during on-pump cardiac surgery.

OBJECTIVE

The aim of this study was to evaluate the cost utility of intraoperative removal of ticagrelor using CytoSorb versus usual care among patients requiring emergent or urgent cardiac surgery in the UK.

METHODS

A de novo decision analytic model, based on current treatment pathways, was developed to estimate the short- and long-term costs and outcomes. Results from randomised clinical trials and national standard sources such as National Health Service (NHS) reference costs were used to inform the model. Costs were estimated from the NHS and Personal Social Services perspective. Deterministic and probabilistic sensitivity analyses (PSAs) explored the uncertainty surrounding the input parameters.

RESULTS

In emergent cardiac surgery, intraoperative removal of ticagrelor using CytoSorb was less costly (£12,933 vs. £16,874) and more effective (0.06201vs. 0.06091 quality-adjusted life-years) than cardiac surgery without physiologic clearance of ticagrelor over a 30-day time horizon. For urgent cardiac surgery, the use of CytoSorb was less costly than any of the three comparators-delaying surgery for natural washout without adjunctive therapy, adjunctive therapy with short-acting antiplatelet agents, or adjunctive therapy with low-molecular-weight heparin. Results from the PSAs showed that CytoSorb has a high probability of being cost saving (99% in emergent cardiac surgery and 53-77% in urgent cardiac surgery, depending on the comparators). Cost savings derive from fewer transfusions of blood products and re-thoracotomies, and shorter stay in the hospital/intensive care unit.

CONCLUSIONS

The implementation of CytoSorb as an intraoperative intervention for patients receiving ticagrelor undergoing emergent or urgent cardiac surgery is a cost-saving strategy, yielding improvement in perioperative and postoperative outcomes and decreased health resource use.

A systematic review and meta-analysis of trainee- versus consultant surgeon-performed elective total hip arthroplasty

Total hip arthroplasty (THA) is one of the most commonly performed orthopaedic procedures. Some concern exists that trainee-performed THA may adversely affect patient outcomes. The aim of this meta-analysis was to compare outcomes following THA performed by surgical trainees and consultant surgeons.

A systematic search was performed to identify articles comparing outcomes following trainee- versus consultant-performed THA. Outcomes assessed included rate of revision surgery, dislocation, deep infection, mean operation time, length of hospital stay and Harris Hip Score (HHS) up to one year. A meta-analysis was conducted using odds ratios (ORs) and weighted mean differences (WMDs). A subgroup analysis for supervised trainees versus consultants was also performed.

The final analysis included seven non-randomized studies of 40 810 THAs, of which 6393 (15.7%) were performed by trainees and 34 417 (84.3%) were performed by consultants. In total, 5651 (88.4%) THAs in the trainee group were performed under supervision. There was no significant difference in revision rate between the trainee and consultant groups (OR 1.09; p = 0.51). Trainees took significantly longer to perform THA compared with consultants (WMD 12.9; p < 0.01). The trainee group was associated with a lower HHS at one year compared with consultants (WMD -1.26; p < 0.01). There was no difference in rate of dislocation, deep infection or length of hospital stay between the two groups.

The present study suggests that supervised trainees can achieve similar clinical outcomes to consultant surgeons, with a slightly longer operation time. In selected patients, trainee-performed THA is safe and effective.

Developing an In-house Interdisciplinary Three-Dimensional Service: Challenges, Benefits, and Innovative Health Care Solutions

Three-dimensional printing (3DP) technologies have been employed in regular medical specialties. They span wide scope of uses, from creating 3D medical models to design and manufacture of Patient-specific implants and guidance devices which help to optimize medical treatments, patient education, and medical training. This article aims to provide an in-depth analysis of factors and aspects to consider when planning to setup a 3D service within a hospital serving various medical specialties. It will also describe challenges that might affect 3D service development and sustainability and describe representative cases that highlight some of the innovative approaches that are possible with 3D technology. Several companies can offer such 3DP service. They are often web based, time consuming, and requiring special call conference arrangements. Conversely, the establishment of in-house specialized hospital-based 3D services reduces the risks to personal information, while facilitating the development of local expertise in this technology. The establishment of a 3D facility requires careful consideration of multiple factors to enable the successful integration with existing services. These can be categorized under: planning, developing and sustaining 3D service; 3D service resources and networking workflow; resources and location; and 3D services quality and regulation management.

Cost comparison of fibrin sealant versus tack screws for mesh fixation in laparoscopic repair of inguinal hernia

OBJECTIVES

Inguinal hernias of the abdominal wall are common accounting for 75% of all hernia defects. They can be treated with laparoscopic surgery using a transabdominal preperitoneal (TAPP) approach. However, in surgery there is some contention on how to conclude the hernia repair, as there are alternatives of using fibrin sealant (FS) or tack screws for fixation of a mesh implant over the defect in the abdominal wall. In this study, we evaluate the economic consequences of using FS vs. tacks for mesh fixation in TAPP inguinal hernia repair for the UK from a hospital perspective.

METHODS

The model was populated with clinical inputs (theater time, hospitalization days, occurrence of seroma, and neuralgia) from a previously conducted study comparing FS and tack screws in patients who had undergone TAPP hernia repair, and cost inputs from official government sources. One-way sensitivity analyses were also conducted to evaluate key drivers of cost analyses.

RESULTS

The average cost per case treated with FS 2 mL Tisseel® and tack screws (ProTack^TM) was £1,098 and £1,348, respectively, for resource expenses paid by the healthcare system. This would suggest a potential savings achieved of £249 per surgery using FS for mesh fixation. The sensitivity analysis showed that the key drivers for the cost difference were a variation in time to complete the surgery, followed by hospitalization days, and lower adverse outcomes such as seroma and neuralgia in the two cohorts.

CONCLUSION

Using FS resulted in cost savings in hospitals based on reduced time to complete surgery, hospitalization time post-op, and lower adverse outcomes. Indirect cost savings were also found in favor of FS when comparing the two alternatives from a societal perspective, as patients were able to return to work more promptly in the FS group versus the tack screws group.

Operating list composition and surgical performance

BACKGROUND

Recent reviews suggest that the way in which surgeons prepare for a procedure (warm up) can affect performance. Operating lists present a natural experiment to explore this phenomenon. The aim was to use a routinely collected large data set on surgical procedures to understand the relationship between case list order and operative performance.

METHOD

Theatre lists involving the 35 procedures performed most frequently by senior surgeons across 38 private hospitals in the UK over 26 months were examined. A linear mixed-effects model and matched analysis were used to estimate the impact of list order and the cost of switching between procedures on a list while controlling for key prognosticators. The influence of procedure method (open versus minimally invasive) and complexity was also explored.

RESULTS

The linear mixed-effects model included 255 757 procedures, and the matched analysis 48 632 pairs of procedures. Repeating the same procedure in a list resulted in an overall time saving of 0·98 per cent for each increase in list position. Switching between procedures increased the duration by an average of 6·48 per cent. The overall reduction in operating time from completing the second procedure straight after the first was 6·18 per cent. This pattern of results was consistent across procedure method and complexity.

CONCLUSION

There is a robust relationship between operating list composition and surgical performance (indexed by duration of operation). An evidence-based approach to structuring a theatre list could reduce the total operating time.

Quality Improvement in Anesthesiology - Leveraging Data and Analytics to Optimize Outcomes

Quality improvement is at the heart of practice of anesthesiology. Objective data are critical for any quality improvement initiative; when possible, a combination of process, outcome, and balancing metrics should be evaluated to gauge the value of an intervention. Quality improvement is an ongoing process; iterative reevaluation of data is required to maintain interventions, ensure continued effectiveness, and continually improve. Dashboards can facilitate rapid analysis of data and drive decision making. Large data sets can be useful to establish benchmarks and compare performance against other providers, practices, or institutions. Audit and feedback strategies are effective in facilitating positive change.
