Agreement Between Physician Evaluation and the Composite Response Index in Diffuse Cutaneous Systemic Sclerosis.

OBJECTIVE: Diffuse cutaneous systemic sclerosis (SSc) is a highly heterogeneous disease. A provisionally approved Composite Response Index in diffuse cutaneous SSc (CRISS) was developed as a 1-year outcome measure for clinical trials. Our goal was to further validate the CRISS by examining agreement between CRISS definitions for improved/non-improved with physicians' evaluation of disease. METHODS: Patient profiles from a large observational cohort were created for 50 random diffuse cutaneous SSc patients of <5 years disease duration with improved CRISS scores after 1 year and 50 with non-improved CRISS scores. Profiles described disease features used during the initial CRISS development at baseline and at 1 year. Each profile was independently rated by 3 expert physicians. Majority opinion determined whether a patient was improved or not improved, and kappa agreement with the CRISS cutoff of 0.6 was calculated. RESULTS: Patients had mean ± SD disease duration of 2.2 ± 1.3 years. There was substantial agreement between the physician majority opinion about each case and the CRISS (κ = 0.76 [95% confidence interval (95% CI) 0.64-0.88]). The agreement between each individual physician opinion and the CRISS was also substantial (κ = 0.70 [95% CI 0.62-0.78]). All CRISS non-improvers were also rated as non-improved by physician majority; however, 12 CRISS improvers were rated as non-improved by physicians. CONCLUSION: There was substantial agreement between the dichotomous CRISS rating and physician assessment of diffuse cutaneous SSc patients after 1 year. This supports the use of a CRISS cutoff at 0.6 for improvement versus non-improvement, although the CRISS tended to rate more patients as improved than did physicians.

Epidemiology and outcomes of gastroschisis in Tasmania.

AIM: To describe the epidemiology and outcomes of gastroschisis in Tasmania. METHODS: A retrospective analysis of all pregnancies complicated by gastroschisis in Tasmania from 1996 to 2015 was undertaken (epidemiology cohort), and the presentation, surgical management and outcomes (surgery cohort) were reviewed for the period between September 1990 and July 2015. RESULTS: Gastroschisis was detected in 58 pregnancies during the 20-year epidemiology cohort period, giving an incidence of 4.4 per 10 000 live births for the 20-year period. Two of the four stillbirths occurred after 36 weeks' gestation. Of the 65 babies with gastroschisis treated at the Royal Hobart Hospital, 51 had a staged surgical repair (silo in 47, stoma formation in 4), and 14 had a primary closure. Staged repair was associated with a significantly longer duration of ventilation and stay in the neonatal intensive care unit. There were six post-natal deaths, all born in the first epoch. Death was significantly associated with the condition of the intestine at delivery (P = 0.02). There were no deaths in babies with simple gastroschisis. Complex gastroschisis was significantly associated with longer duration of total parenteral nutrition (P = 0.0002) and longer stay in hospital (P = 0.03). CONCLUSIONS: The incidence of gastroschisis in Tasmania is similar to that reported in other Australian regions and has not increased over the 20-year period of study. The high risk of stillbirth, and the significant association between mortality and the condition of the intestine at birth necessitates close fetal surveillance. Complex gastroschisis imposes a significant burden on hospital resources.

Experience with tofacitinib in Canada: patient characteristics and treatment patterns in rheumatoid arthritis over 3 years.

OBJECTIVES: To describe characteristics, treatment patterns and persistence in patients with RA treated with tofacitinib, an oral Janus kinase inhibitor, in Canadian clinical practice between 1 June 2014 and 31 May 2017. METHODS: Data were obtained from the tofacitinib eXel support programme. Baseline demographics and medication history were collected via patient report/special authorization forms; reasons for discontinuation were captured by patient report. Treatment persistence was estimated using Kaplan-Meier methods, with data censored at last follow-up. Cox regression was applied to analyse baseline characteristics associated with treatment discontinuation. RESULTS: The number of patients with RA enrolled from 2014 to 2017 was 4276; tofacitinib utilization increased during that period, as did the proportion of biologic (b) DMARD-naïve patients prescribed tofacitinib. Of patients who initiated tofacitinib, 1226/3678 (33.3%) discontinued, mostly from lack of efficacy (35.7%) and adverse events (26.9%). Persistence was 62.7% and 49.6% after 1 and 2 years of treatment, respectively. Prior bDMARD experience predicted increased tofacitinib discontinuation (vs bDMARD-naïve, P < 0.001). Increased retention was associated with older age (56-65 years and >65 years vs ⩽45 years; P < 0.05), and time since diagnosis of 15 to <20 years (vs <5 years; P < 0.01). In bDMARD-naïve, post-1 bDMARD, post-2 bDMARD and post-⩾3 bDMARD patients, median survival was >730, 613, 667 and 592 days, respectively. CONCLUSION: Since 2014, tofacitinib use in Canadian patients with RA increased, especially among bDMARD-naïve/post-1 bDMARD patients. Median drug survival was ∼2 years. Likelihood of persistence increased for bDMARD-naïve (vs bDMARD-experienced) patients and those aged ⩾56 (vs ⩽45) years.

Tune-In and Time-Out: Toward Surgeon-Led Prevention of "Never" Events.

INTRODUCTION: The World Health Organization (WHO) distributed a surgical safety checklist in 2008 in a bid to improve patient safety and quality of care in the operating theater. Adherence to the checklist has been shown to reduce "never" events, for example, wrong site surgery. The aim of this quality improvement study was to determine the current adherence by surgeons to the checklist at The Royal Hobart Hospital. METHODS: This is a retrospective audit of the digital medical records of 100 consecutive emergency operations performed at The Royal Hobart Hospital. The time-out section of the WHO Surgical Safety Checklist was assessed for completeness. Second, an anonymized survey of theater nursing staff was performed to determine current adherence by surgeons with the time-out. RESULTS: The time-out was completed in 79% of emergency procedures. There were no never events in the patient cohort studied. There was overwhelming support among theater nurses for a surgeon-led time-out. Formal education on the use of the WHO Safe Surgery Checklist is lacking. Most theater nurses have experienced hostility from surgeons when conducting a time-out. DISCUSSION: This work is a step on the way to surgeon-led prevention of never events. Finding a completed time-out in the patient notes does not guarantee surgeon support for or contribution to the time-out process. The findings will inform combined nursing and surgeon education sessions, and together with executive-level support, improved surgeon cooperation with the time-out will inculcate a culture of safety for patients and improve harmony among staff groups.

The Scleroderma Patient-Centered Intervention Network Cohort: baseline clinical features and comparison with other large scleroderma cohorts.

Objectives: The Scleroderma Patient-centered Intervention Network (SPIN) Cohort is a web-based cohort designed to collect patient-reported outcomes at regular intervals as a framework for conducting trials of psychosocial, educational, self-management and rehabilitation interventions for patients with SSc. The aim of this study was to present baseline demographic, medical and patient-reported outcome data of the SPIN Cohort and to compare it with other large SSc cohorts. Methods: Descriptive statistics were used to summarize SPIN Cohort characteristics; these were compared with published data of the European Scleroderma Trials and Research (EUSTAR) and Canadian Scleroderma Research Group (CSRG) cohorts. Results: Demographic, organ involvement and antibody profile data for SPIN (N = 1125) were generally comparable with that of the EUSTAR (N = 7319) and CSRG (N = 1390) cohorts. There was a high proportion of women and White patients in all cohorts, though relative proportions differed. Scl70 antibody frequency was highest in EUSTAR, somewhat lower in SPIN, and lowest in CSRG, consistent with the higher proportion of interstitial lung disease among dcSSc patients in SPIN compared with in CSRG (48.5 vs 40.3%). RNA polymerase III antibody frequency was highest in SPIN and remarkably lower in EUSTAR (21.1 vs 2.4%), in line with the higher prevalence of SSc renal crisis (4.5 vs 2.1%) in SPIN. Conclusion: Although there are some differences, the SPIN Cohort is broadly comparable with other large prevalent SSc cohorts, increasing confidence that insights gained from the SPIN Cohort should be generalizable, although it should be noted that all three cohorts include primarily White participants.

Calcinosis is associated with digital ischaemia in systemic sclerosis-a longitudinal study.

OBJECTIVE: To determine if ischaemia is a causal factor in the development of calcinosis in SSc. METHODS: Patients with SSc were assessed yearly. Physicians reported the presence of calcinosis, digital ischaemia (digital ulcers, digital necrosis/gangrene, loss of digital pulp on any digits and/or auto- or surgical digital amputation) and nailfold capillary dropout assessed using a dermatoscope. The number of digits with digital ischaemia was used as an assessment of the severity of digital ischaemia. SSc specific antibodies were detected with a line immunoassay. Multiple logistic regression and Cox proportional hazards models were generated to determine associations between calcinosis, digital ischaemia and capillary dropout. RESULTS: One thousand three hundred and five patients were included in this study, of whom 300 (23.0%) had calcinosis at study entry. In a cross-sectional multivariate analysis, at baseline, calcinosis was associated with digital ischaemia (odds ratio (OR) = 2.37, 95% CI: 1.66, 3.39), severity of ischaemia (OR = 1.12, 95% CI: 1.06, 1.18), capillary dropout (OR = 1.41, 95% CI: 1.05, 1.89), ACAs (OR = 1.68, 95% CI: 1.17, 2.43) and anti-RNA polymerase III antibodies (OR = 1.77, 95% CI: 1.08, 2.89). Current use of calcium channel blockers was inversely associated with the presence of calcinosis (OR = 0.70, 95% CI: 0.52, 0.96). Of the 805 patients with no calcinosis at study entry and at least one follow-up visit, 215 (26.7%) developed calcinosis during follow-up. Significant baseline predictors of the development of calcinosis in follow-up were digital ischaemia (hazard ratio (HR) = 1.82, 95% CI: 1.30, 2.54), capillary dropout (HR = 1.46, 95% CI: 1.08, 1.99), dcSSc (HR = 1.57, 95% CI: 1.11, 2.21), ACA (HR = 2.18, 95% CI: 1.50, 3.17) and anti-RNA polymerase III antibodies (HR = 2.58, 95% CI: 1.65, 4.04). CONCLUSION: Ischaemia may play a role in the development of calcinosis in SSc.

Genetic susceptibility loci of idiopathic interstitial pneumonia do not represent risk for systemic sclerosis: a case control study in Caucasian patients.

BACKGROUND: Systemic sclerosis (SSc)-related interstitial lung disease (ILD) has phenotypic similarities to lung involvement in idiopathic interstitial pneumonia (IIP). We aimed to assess whether genetic susceptibility loci recently identified in the large IIP genome-wide association studies (GWASs) were also risk loci for SSc overall or severity of ILD in SSc. METHODS: A total of 2571 SSc patients and 4500 healthy controls were investigated from the US discovery GWAS and additional US replication cohorts. Thirteen IIP-related selected single nucleotide polymorphisms (SNPs) were genotyped and analyzed for their association with SSc. RESULTS: We found an association of SSc with the SNP rs6793295 in the LRRC34 gene (OR = 1.14, CI 95 % 1.03 to 1.25, p value = 0.009) and rs11191865 in the OBFC1 gene (OR = 1.09, CI 95 % 1.00 to 1.19, p value = 0.043) in the discovery cohort. Additionally, rs7934606 in MUC2 (OR = 1.24, CI 95 % 1.01 to 1.52, p value = 0.037) was associated with SSc-ILD defined by imaging. However, these associations failed to replicate in the validation cohort. Furthermore, SNPs rs2076295 in DSP (ß = -2.29, CI 95 % -3.85 to -0.74, p value = 0.004) rs17690703 in SPPL2C (ß = 2.04, CI 95 % 0.21 to 3.88, p value = 0.029) and rs1981997 in MAPT (ß = 2.26, CI 95 % 0.35 to 4.17, p value = 0.02) were associated with percent predicted forced vital capacity (FVC%) even after adjusting for the anti-topoisomerase (ATA)-positive subset. However, these associations also did not replicate in the validation cohort. CONCLUSIONS: Our results add new evidence that SSc and SSc-related ILD are genetically distinct from IIP, although they share phenotypic similarities.

Relationship Between Disease Characteristics and Oral Radiologic Findings in Systemic Sclerosis: Results From a Canadian Oral Health Study.

OBJECTIVE: Systemic sclerosis (SSc; scleroderma) is associated with a wide periodontal ligament (PDL) and mandibular erosions. We investigated the clinical correlates of SSc with these radiologic abnormalities. METHODS: Subjects from the Canadian Scleroderma Research Group cohort underwent detailed radiologic examinations. Associations between radiologic abnormalities and clinical manifestations of SSc were examined with univariate and multivariate analyses. RESULTS: The study included 159 subjects; 90.6% were women, the mean ± SD age was 56 ± 10 years, diffuse disease was present in 28.3%, and mean ± SD disease duration was 13.7 ± 8.4 years. Widening of the PDL involving at least 1 tooth was present in 38% of subjects, and 14.5% had at least 1 site in the mandible with an erosion. In analyses adjusting for age, disease duration, sex, smoking, and education, we found significant associations between the number of teeth with widening of the PDL and disease severity assessed by the physician global assessment (PGA) (relative risk [RR] 1.19, 95% confidence interval [95% CI] 1.02-1.39, P = 0.028). Analyses replacing the PGA with the skin score, disease subset, or anti-topoisomerase I antibodies confirmed the relationship with indices of disease severity. There was no relationship between either the number of teeth with periodontal disease or the number of missing teeth, and the number of teeth with wide PDL. A smaller interdental distance (RR 0.89, 95% CI 0.82-0.97, P = 0.006), but not disease severity, facial skin score, or ischemia was associated with a larger number of erosions. CONCLUSION: In SSc, a wide PDL may reflect generalized overproduction of collagen, and mandibular erosions are related to local factors in the oral cavity.

Antimalarial drugs alone may still have a role in rheumatoid arthritis.

OBJECTIVES: Antimalarials have been used for the treatment of rheumatoid arthritis (RA) for several decades. Current guidelines do not include the use of these drugs alone for RA patients. The purpose of the study is to review RA patients, to find those who have done well on antimalarials alone, and see if there are common features that predict good treatment outcome with these drugs. METHODS: This is a retrospective chart review of patients who have been successfully treated with antimalarials alone. Patients who were attending routine follow-up and were seemingly in remission defined by no swollen or tender joints were selected over a 6-month period. Those who had being doing well but were now or had been on other agents were not included. The background data were reviewed to see if there were any common initial characteristics. RESULTS: Thirty-three patients were seen who had been administered antimalarials alone and where initial data were available. Patients remain in clinical remission. Based on clinical observation, inflammatory markers, and radiographic reports, in the follow-up visits, they remain with no signs of inflammation and no new erosions on radiograph. Initial bone erosions on 2 patients remain stable over the years. CONCLUSIONS: There are some patients with confirmed RA who without doubt respond well to antimalarials alone. It is hard to objectively measure whether mild disease activity, early treatment initiation, lack of smoking, or other factors are contributing to a good treatment response.

The Canadian Systemic Sclerosis Oral Health Study IV: oral radiographic manifestations in systemic sclerosis compared with the general population.

OBJECTIVE: The aim of this study was to compare oral radiologic abnormalities associated with systemic sclerosis (SSc) against abnormalities in the general population. STUDY DESIGN: Patients with SSc and healthy controls were enrolled in a multi-site cross-sectional study. Included in the radiology examination were a panoramic radiograph, four bitewings, and an anterior mandibular periapical radiograph. Radiographs were evaluated by two oral and maxillofacial radiologists tested for interobserver and intraobserver reliability. Chi-squared tests, Fisher exact tests, and Mann Whitney U tests were used to summarize the radiologic manifestations of patients and controls. RESULTS: We assessed 163 SSc patients and 231 controls. Widening of the periodontal ligament space (PLS) (P < .001), with higher percentage of teeth with PLS widening (P < .001), was significantly more frequent in patients with SSc than in controls. The most significant differences between the two groups were found in the molars and premolars (P < .001). Moreover, 26% of the patients with SSc had a periapical PLS greater than 0.19 mm compared with 13% of the controls (P = .003). Patients with SSc had significantly more erosions compared with controls (14.5% vs. 3.6%; P < .001), mostly in the condyles (P = .022), coronoid processes (P = .005) and other locations (P = .012). CONCLUSION: Patients with SSc had more teeth with PLS widening and erosions of the mandible compared with controls.

Antinuclear antibody-negative systemic sclerosis.

OBJECTIVE: To examine the demographic and clinical characteristics of systemic sclerosis (SSc) patients without antinuclear antibodies (ANA) compared to ANA-positive patients. METHODS: SSc patients enrolled in the Scleroderma Family Registry and DNA Repository were included. Relevant demographic and clinical data were entered by participating sites or obtained by chart review. ANA and SSc-related antibodies were determined in all investigated patients using commercially available kits at our laboratories. RESULTS: This study included 3249 patients, of whom 208 (6.4%) were ANA negative. The proportion of male patients was higher in the ANA-negative group (OR = 1.65; p = 0.008). ANA-negative patients experienced less vasculopathic manifestations of SSc. The percent predicted diffusing capacity of carbon monoxide (DLCO) was higher in ANA-negative patients (p = 0.03). Pulmonary arterial hypertension (PAH) per right heart catheterization was less common in the ANA-negative group (OR = 0.28; p = 0.03). Furthermore, patients with negative ANA had a lower prevalence of telangiectasias and digital ulcers/pits (OR = 0.59, p = 0.03 and OR = 0.38, p = 0.01, respectively). Although diffuse cutaneous involvement was more common, the modified Rodnan Skin Score (mRSS) was lower in the ANA-negative group (2.4 points lower, p = 0.05). Furthermore, they experienced more malabsorption (p = 0.05). There was no difference in the frequency of pulmonary fibrosis or scleroderma renal crisis. All-cause mortality was not different between the 2 groups (p = 0.28). CONCLUSIONS: In conclusion, the results of this study suggest that SSc patients who are ANA negative constitute a distinct subset of SSc with less vasculopathy (less PAH, digital ulcers, and fewer telangiectasias), a greater proportion of males, and possibly, more frequent lower gastrointestinal involvement.

The Canadian systemic sclerosis oral health study II: the relationship between oral and global health-related quality of life in systemic sclerosis.

OBJECTIVE: Both oral and global health-related quality of life (HRQoL) are markedly impaired in SSc. In this study we aimed to determine the degree of association between oral HRQoL and global HRQoL in SSc. METHODS: Subjects were recruited from the Canadian Scleroderma Research Group registry. Global HRQoL was measured using the Medical Outcomes Trust 36-item Short Form Health Survey (SF-36) and oral HRQoL with the Oral Health Impact Profile (OHIP). The Medsger Disease Severity Score was used to determine organ involvement. Multivariate regression models determined the independent association of the OHIP with the SF-36 after adjusting for confounders. RESULTS: This study included 156 SSc subjects. The majority (90%) were women, with a mean age of 56 years, mean disease duration 13.8 years (s.d. 8.5) and 29% of the subjects had dcSSc. Mean total OHIP score was 40.8 (s.d. 32.4). Mean SF-36 mental component summary (MCS) score was 49.7 (s.d. 11.1) and physical component summary (PCS) score was 37.0 (s.d. 10.7). In adjusted analyses, the total OHIP score was significantly associated with the SF-36 MCS and PCS, accounting for 9.7% and 5.6% of their respective variances. Measures of disease severity were not related to OHIP score. CONCLUSION: Oral HRQoL in SSc is independently associated with global HRQoL. Oral HRQoL, however, is not related to physician-assessed disease severity. This suggests that physicians may be disregarding issues related to oral health. HRQoL is an additional dimension of HRQoL not captured by generic instruments such as the SF-36.

2013 American College of Rheumatology/European League against rheumatism classification criteria for systemic sclerosis outperform the 1980 criteria: data from the Canadian Scleroderma Research Group.

OBJECTIVE: The goal of this study was to determine the sensitivity of the new 2013 classification criteria for systemic sclerosis (SSc; scleroderma) in an independent cohort of SSc subjects and to assess the contribution of individual items of the criteria to the overall sensitivity. METHODS: SSc subjects from the Canadian Scleroderma Research Group cohort were assessed. Sensitivity was determined in several subgroups of patients. In patients without the criterion of skin thickening proximal to the metacarpophalangeal (MCP) joints, we recalculated sensitivity after removing the individual criterion. RESULTS: A total of 724 SSc patients were included. Most were women (86%), mean age was 55.8 years, mean disease duration was 10.9 years, and 59% had limited cutaneous SSc (lcSSc). Overall, the sensitivity of the 2013 criteria was 98.3% compared to 88.3% for the 1980 criteria. This pattern was consistent among those with lcSSc (98.8% versus 85.6%), anticentromere antibodies (98.9% versus 79.8%), disease duration ≤3 years (98.7% versus 84.7%), and no skin involvement proximal to the MCP joints (97% versus 60%). In the latter subgroup, removing Raynaud's phenomenon and sclerodactyly from the criteria reduced the sensitivity to 77% and 79%, respectively. Removing both sclerodactyly and puffy fingers reduced the sensitivity to 62%. CONCLUSION: The 2013 SSc classification criteria classify more SSc patients than the 1980 criteria. The improvement in sensitivity is most striking in those with lcSSc, especially those without skin involvement proximal to the MCP joints. The addition of Raynaud's phenomenon and puffy fingers to the 2013 criteria accounts for important gains in sensitivity.

Relationship between disease characteristics and orofacial manifestations in systemic sclerosis: Canadian Systemic Sclerosis Oral Health Study III.

OBJECTIVE: Systemic sclerosis (SSc; scleroderma) is associated with decreased saliva production and interincisal distance, more missing teeth, and periodontal disease. We undertook this study to determine the clinical correlates of SSc with these oral abnormalities. METHODS: Subjects were recruited from the Canadian Scleroderma Research Group cohort. Detailed dental and clinical examinations were performed according to standardized protocols. Associations between dental abnormalities and selected clinical and serologic manifestations of SSc were examined. RESULTS: One hundred sixty-three SSc subjects were included: 90% women, mean ± SD age 56 ± 11 years, mean ± SD disease duration 14 ± 8 years, 72% with limited cutaneous disease, and 28% with diffuse cutaneous disease. Decreased saliva production was associated with Sjögren's syndrome-related autoantibodies (ß = -43.32; 95% confidence interval [95% CI] -80.89, -5.75), but not with disease severity (ß = -2.51; 95% CI -8.75, 3.73). Decreased interincisal distance was related to disease severity (ß = -1.02; 95% CI -1.63, -0.42) and the modified Rodnan skin thickness score (ß = -0.38; 95% CI -0.53, -0.23). The number of missing teeth was associated with decreased saliva production (relative risk [RR] 0.97; 95% CI 0.94, 0.99), worse hand function (RR 1.52; 95% CI 1.13, 2.02), and the presence of gastroesophageal reflux disease (GERD; RR 1.68 [95% CI 1.14, 2.46]). No clinical or serologic variables were correlated with periodontal disease. CONCLUSION: In SSc, diminished interincisal distance is related to overall disease severity. Decreased saliva production is related to concomitant Sjögren's syndrome antibodies. Tooth loss is associated with poor upper extremity function, GERD, and decreased saliva. The etiology of excess periodontal disease is likely multifactorial and remains unclear.

The Canadian systemic sclerosis oral health study: orofacial manifestations and oral health-related quality of life in systemic sclerosis compared with the general population.

OBJECTIVE: The aim of this study was to compare oral abnormalities and oral health-related quality of life (HRQoL) of patients with SSc with the general population. METHODS: SSc patients and healthy controls were enrolled in a multisite cross-sectional study. A standardized oral examination was performed. Oral HRQoL was measured with the Oral Health Impact Profile (OHIP). Multivariate regression analyses were performed to identify associations between SSc, oral abnormalities and oral HRQoL. RESULTS: We assessed 163 SSc patients and 231 controls. SSc patients had more decayed teeth (SSc 0.88, controls 0.59, P = 0.0465) and periodontal disease [number of teeth with pocket depth (PD) >3 mm or clinical attachment level (CAL) ≥5.5 mm; SSc 5.23, controls 2.94, P < 0.0001]. SSc patients produced less saliva (SSc 147.52 mg/min, controls 163.19 mg/min, P = 0.0259) and their interincisal distance was smaller (SSc 37.68 mm, controls 44.30 mm, P < 0.0001). SSc patients had significantly reduced oral HRQoL compared with controls (mean OHIP score: SSc 41.58, controls 26.67, P < 0.0001). Multivariate regression analyses confirmed that SSc was a significant independent predictor of missing teeth, periodontal disease, interincisal distance, saliva production and OHIP scores. CONCLUSION: Subjects with SSc have impaired oral health and oral HRQoL compared with the general population. These data can be used to develop targeted interventions to improve oral health and HRQoL in SSc.

Paediatric laparoscopic hernia repair: Ex vivo skills in the reduced training era.

INTRODUCTION: Changes to surgical working hours have resulted in shorter training times and fewer learning opportunities. Tools that develop surgical skills ex-vivo are of particular interest in this era. Laparoscopic skills are regarded as essential by many for modern paediatric surgery practice. Several generic skills models have been reported and validated. However, there is limited evidence regarding the role of procedure specific models. Here, a laparoscopic paediatric hernia repair model is trialled with surgical trainees and their competence compared with consultant colleagues. PATIENTS AND METHODS: An ex-vivo paediatric inguinal hernia repair model was devised. Surgical trainees from 5 specialist centres were recruited and performed multiple standardised repairs. RESULTS: 23 trainees performed 192 repairs. Experts performed 10 repairs for comparison. Trainees were timed performing the repair and their accuracy measured. With repeated attempts trainee's timings and accuracy improved until by the 10 th repair they were no different from benchmark consultant scores. CONCLUSION: A simple, procedure specific ex-vivo training model has been evaluated for laparoscopic hernia training in paediatric surgery. The results suggest improvements in competence with repetition. Trainee and benchmark consultant scores are no different by the 10 th trainee attempt. We conclude that this model may have a valuable role in the training and assessment of future paediatric surgeons.
