Risk of Recurrent Disease and Surgery Following an Admission for Acute Diverticulitis.

BACKGROUND: Diverticular disease accounts for significant morbidity and mortality and may take the form of recurrent episodes of acute diverticulitis. The role of elective surgery is not clearly defined. OBJECTIVE: This study aimed to define the rate of hospital admission for recurrent acute diverticulitis and risk factors associated with recurrence and surgery. DESIGN: This is a retrospective population-based cohort study. SETTINGS: National Health Service hospital admissions for acute diverticulitis in England between April 2006 and March 2011 were reviewed. PATIENTS: Hospital Episode Statistics data identified adult patients with the first episode of acute diverticulitis (index admission), and then identified recurrent admissions and elective or emergency surgery for acute diverticulitis during a minimum follow-up period of 4 years. Exclusion criteria included previous diagnoses of acute diverticulitis, colorectal cancer, or GI bleeding, and prior colectomy or surgery or death during the index admission. INTERVENTIONS: There were no interventions. MAIN OUTCOME MEASURES: The primary outcomes measured were recurrent admissions for acute diverticulitis and patients requiring either elective or emergency surgery during the study period. RESULTS: Some 65,162 patients were identified with the first episode of acute diverticulitis. The rate of hospital admission for recurrent acute diverticulitis was 11.2%. A logistic regression model examined factors associated with recurrent acute diverticulitis and surgery: patient age, female sex, smoking, obesity, comorbidity score >20, dyslipidemia, and complicated acute diverticulitis increased the risk of recurrent acute diverticulitis. There was an inverse relationship between patient age and recurrence. Similar factors were associated with elective and emergency surgery. LIMITATIONS: The cases of acute diverticulitis required inpatient management and the use of Hospital Episode Statistics, relying on the accuracy of diagnostic coding. CONCLUSIONS: This is the largest study assessing the rates of hospital admission for recurrent acute diverticulitis. Knowledge of the rate and risk factors for recurrent acute diverticulitis is required to aid discussion and decision making with patients regarding the need and timing of elective surgery. Some factors associated with recurrence are modifiable; therefore, weight reduction and smoking cessation can be championed. See Video Abstract at http://links.lww.com/DCR/A449.

Measures of performance and proficiency in robotic assisted surgery: a systematic review.

Robotic assisted surgery (RAS) has seen a global rise in adoption. Despite this, there is not a standardised training curricula nor a standardised measure of performance. We performed a systematic review across the surgical specialties in RAS and evaluated tools used to assess surgeons' technical performance. Using the PRISMA 2020 guidelines, Pubmed, Embase and the Cochrane Library were searched systematically for full texts published on or after January 2020-January 2022. Observational studies and RCTs were included; review articles and systematic reviews were excluded. The papers' quality and bias score were assessed using the Newcastle Ottawa Score for the observational studies and Cochrane Risk Tool for the RCTs. The initial search yielded 1189 papers of which 72 fit the eligibility criteria. 27 unique performance metrics were identified. Global assessments were the most common tool of assessment (n = 13); the most used was GEARS (Global Evaluative Assessment of Robotic Skills). 11 metrics (42%) were objective tools of performance. Automated performance metrics (APMs) were the most widely used objective metrics whilst the remaining (n = 15, 58%) were subjective. The results demonstrate variation in tools used to assess technical performance in RAS. A large proportion of the metrics are subjective measures which increases the risk of bias amongst users. A standardised objective metric which measures all domains of technical performance from global to cognitive is required. The metric should be applicable to all RAS procedures and easily implementable. Automated performance metrics (APMs) have demonstrated promise in their wide use of accurate measures.

Utilising an accelerated Delphi process to develop consensus on the requirement and components of a pre-procedural core robotic surgery curriculum.

Robot-assisted surgery (RAS) continues to grow globally. Despite this, in the UK and Ireland, it is estimated that over 70% of surgical trainees across all specialities have no access to robot-assisted surgical training (RAST). This study aimed to provide educational stakeholders guidance on a pre-procedural core robotic surgery curriculum (PPCRC) from the perspective of the end user; the surgical trainee. The study was conducted in four Phases: P1: a steering group was formed to review current literature and summarise the evidence, P2: Pan-Specialty Trainee Panel Virtual Classroom Discussion, P3: Accelerated Delphi Process and P4: Formulation of Recommendations. Forty-three surgeons in training representing all surgical specialties and training levels contributed to the three round Delphi process. Additions to the second- and third-round surveys were formulated based on the answers and comments from previous rounds. Consensus opinion was defined as ≥ 80% agreement. There was 100% response from all three rounds. The resulting formulated guidance showed good internal consistency, with a Cronbach alpha of > 0.8. There was 97.7% agreement that a standardised PPCRC would be advantageous to training and that, independent of speciality, there should be a common approach (95.5% agreement). Consensus was reached in multiple areas: 1. Experience and Exposure, 2. Access and context, 3. Curriculum Components, 4 Target Groups and Delivery, 5. Objective Metrics, Benchmarking and Assessment. Using the Delphi methodology, we achieved multispecialty consensus among trainees to develop and reach content validation for the requirements and components of a PPCRC. This guidance will benefit from further validation following implementation.

Survival of autologous osteochondral grafts in the knee and factors influencing outcome.

The primary aim of this retrospective study was to determine the medium-term survival of autologous osteochondral grafts (mosaicplasty) in the knee. The secondary aims were to evaluate any reason for failure, and to ascertain if age, gender, BMI, previous or associated knee surgery, site or size of the osteochondral graft had any influence on outcome. Fifty-five patients undergoing an autologous osteochondral graft procedure between 1999 and 2008 were evaluated, with a mean follow-up of 5.9 years (range 0.5 to 10.5). Loosening, graft degeneration or subsequent surgery in the form of arthroplasty, revision autologous osteochondral graft or any other osteochondral procedure, and an Oxford knee score above 49.7 (see text) were considered as failure. Kaplan-Meier analysis demonstrated an 87.5% survival at 8 years (95% CI 72% to 97%). The mean Oxford score at follow-up was 163% (95% CI 10.6% to 22.1%) at follow-up. Two of 6 failures occurred in patients with varus malalignment. Linear regression analysis demonstrated an improved outcome in Oxford knee score in younger patients. Gender, BMI, previous or associated knee surgery, site and size of the graft had no influence on outcome. The authors consider autologous osteochondral grafting as a reliable method of treatment in the medium-term for young patients with small contained articular cartilage lesions up to 4 cm2. Careful attention should be paid to the mechanical axis (varus) prior to grafting. Long-term studies are necessary.

Patient and other factors influencing the prescribing of cardiovascular prevention therapy in the general practice setting with and without nurse assessment.

BACKGROUND: Although guidelines indicate when patients are eligible for antihypertensives and statins, little is known about whether general practitioners (GPs) follow this guidance. OBJECTIVE: To determine the factors influencing GPs decisions to prescribe cardiovascular prevention drugs. DESIGN OF STUDY: Secondary analysis of data collected on patients whose cardiovascular risk factors were measured as part of a controlled study comparing nurse-led risk assessment (four practices) with GP-led risk assessment (two practices). SETTING: Six general practices in the West Midlands, England. PATIENTS: Five hundred patients: 297 assessed by the project nurse, 203 assessed by their GP. MEASUREMENTS: Cardiovascular risk factor data and whether statins or antihypertensives were prescribed. Multivariable logistic regression models investigated the relationship between prescription of preventive treatments and cardiovascular risk factors. RESULTS: Among patients assessed by their GP, statin prescribing was significantly associated only with a total cholesterol concentration ≥ 7 mmol/L and antihypertensive prescribing only with blood pressure ≥ 160/100 mm Hg. Patients prescribed an antihypertensive by their GP were five times more likely to be prescribed a statin. Among patients assessed by the project nurse, statin prescribing was significantly associated with age, sex, and all major cardiovascular risk factors. Antihypertensive prescribing was associated with blood pressures ≥ 140/90 mm Hg and with 10-year cardiovascular risk. LIMITATIONS: Generalizability is limited, as this is a small analysis in the context of a specific cardiovascular prevention program. CONCLUSIONS: GP prescribing of preventive treatments appears to be largely determined by elevation of a single risk factor. When patients were assessed by the project nurse, prescribing was much more consistent with established guidelines.
