RESUMO
BACKGROUND: Ischaemic strokes are medical emergencies, and reperfusion treatment, most commonly intravenous thrombolysis, is time-critical. Thrombolysis administration relies on well-organised pathways of care with highly skilled and efficient clinicians. Simulation training is a widespread teaching modality, but results from studies on the impact of this intervention have yet to be synthesised. This systematic review and meta-analysis aimed to synthesise the evidence and provide a recommendation regarding the effects of simulation training for healthcare professionals on door-to-needle time in the emergency thrombolysis of patients with ischaemic stroke. METHODS: Seven electronic databases were systematically searched (last updated 12th July 2023) for eligible full-text articles and conference abstracts. Results were screened for relevance by two independent reviewers. The primary outcome was door-to-needle time for recombinant tissue plasminogen activator administration in emergency patients with ischaemic stroke. The secondary outcomes were learner-centred, improvements in knowledge and communication, self-perceived usefulness of training, and feeling 'safe' in thrombolysis-related decision-making. Data were extracted, risk of study bias assessed, and analysis was performed using RevMan™ software (Web version 5.6.0, The Cochrane Collaboration). The quality of the evidence was assessed using the Medical Education Research Study Quality Instrument. RESULTS: Eleven studies were included in the meta-analysis and nineteen in the qualitative synthesis (n = 20,189 total patients). There were statistically significant effects of simulation training in reducing door-to-needle time; mean difference of 15 min [95% confidence intervals (CI) 8 to 21 min]; in improving healthcare professionals' acute stroke care knowledge; risk ratio (RR) 0.42 (95% CI 0.30 to 0.60); and in feeling 'safe' in thrombolysis-related decision-making; RR 0.46 (95% CI 0.36 to 0.59). Furthermore, simulation training improved healthcare professionals' communication and was self-perceived as useful training. CONCLUSION: This meta-analysis showed that simulation training improves door-to-needle times for the delivery of thrombolysis in ischaemic stroke. However, results should be interpreted with caution due to the heterogeneity of the included studies.
RESUMO
Background: Most patients with end-stage renal disease (ESRD) are managed with dialysis and less commonly kidney transplantation. However, not all are suitable for or desire either of these renal replacement therapies. Conservative management (CM) is an option. However, the selection of CM is often not easy for patients and clinicians. The aim of this systematic review is to identify the key factors that influence the selection of CM for ESRD. Methods: Medline, Embase, PsychINFO, and CINAHL Plus were systematically searched from inception to 10 September 2021. Titles/abstracts and full texts were independently screened by two reviewers. Reference lists of included articles were searched. An update search via PubMed was conducted on 10 August 2023. A narrative synthesis of review findings was conducted. Results: At the end of the screening process, 15 qualitative and 8 survey articles were selected. Reference checking yielded no additional relevant studies. Main themes were: (i) Patient-specific factors; (ii) Clinician-specific factors; (iii) Organisational factors; and (iv) National and international factors. Patient-specific factors were awareness and perceptions of CM and dialysis, beliefs about survival, preferred treatment outcomes and influence of family/caregivers and clinicians. Clinician-specific factors included perceptions of CM as 'non-intervention', perceptions of clinician role in the decision-making process, and confidence and ability to initiate sensitive treatment discussions. Relationships with and involvement of other healthcare professionals, time constraints, and limited clinical guidance were also important factors. Conclusions: An improvement in the provision of education regarding CM for patients, caregivers, and clinicians is essential. Robust studies are required to generate crucial evidence for the development of stronger recommendations and guidance for clinicians.
RESUMO
AIM: To establish, for the first time, the clinically important differences for the ICIQ-UI-SF and ICIQ-FLUTS questionnaires following surgical and conservative treatments for stress-predominant urinary incontinence in women. METHODS: Data from the SIMS and OPAL randomised controlled trials were analysed using an anchor-based method. Clinically important difference (CID; score change indicating a successful outcome) and minimal important difference (MID; score change indicating the smallest noticeable difference) were estimated using the PGI-I scale as the anchor. RESULTS: For ICIQ-UI-SF, following surgical management, CIDs were 5.0 (95%CI 4.3, 5.6) at 1 year and 4.9 points (95%CI 4.2, 5.5) at 3 years, while following conservative management, CIDs were 4.0 (95%CI 3.4, 4.5) at 1 year and 4.6 points (95%CI 4.0, 5.2) at 2 years. For ICIQ-FLUTS, the CID was 3.4 points (95%CI 2.9, 4.0) at 1 year for both surgical and conservative management. MIDs for ICIQ-UI-SF, after surgical treatment, were 4.7 (95% CI 3.2, 6.1) at 1 year and 1.6 points (95%CI -0.2, 3.0) at 3 years, and after conservative treatment they were 1.7 (95% CI 1.0, 2.5) at 1 year and 1.9 points (95%CI 1.1, 2.7) at 2 years. For ICIQ-FLUTS, MIDs were 1.8 (95% CI 0.6, 3.1) at 1 year and 3.2 points (95%CI 2.0, 4.4) at 2 years after surgical treatment, and 1.3 (95%CI 0.6, 1.9) at 1 year and 1.9 points (95%CI 1.1, 2.6) at 2 years after conservative treatment. CONCLUSION: Our study is the first to establish the CID for the ICIQ-UI-SF and ICIQ-FLUTS that women would associate with a successful outcome 3-years post-surgery and 2-years post-conservative treatment of stress-predominant urinary incontinence. The MID was lower following conservative compared to surgical treatment.

To evaluate the clinical efficacy, safety, and cost-effectiveness of endometrial ablation or resection (E:A/R) compared to hysterectomy for the treatment of heavy menstrual bleeding. Literature search was conducted, and randomized control trials (RCTs) comparing (E:A/R) versus hysterectomy were reviewed. The search was last updated in November 2022. Twelve RCTs with 2,028 women (hysterectomy: n=977 vs. [E:A/R]: n=1,051) were included in the analyzis. The meta-analysis revealed that the hysterectomy group showed improved patient-reported and objective bleeding symptoms more than those of the (E:A/R) group, with risk ratios of (mean difference [MD], 0.75; 95% confidence intervals [CI], 0.71 to 0.79) and (MD, 44.00; 95% CI, 36.09 to 51.91), respectively. Patient satisfaction was higher post-hysterectomy than (E:A/R) at 2 years of follow-up, but this effect was absent with long-term follow-up. (E:A/R) is considered an alternative to hysterectomy as a surgical management for heavy menstrual bleeding. Although both procedures are highly effective, safe, and improve the quality of life, hysterectomy is significantly superior at improving bleeding symptoms and patient satisfaction for up to 2 years. However, it is associated with longer operating and recovery times and a higher rate of postoperative complications. The initial cost of (E:A/R) is less than the cost of hysterectomy, but further surgical requirements are common; therefore, there is no difference in the cost for long-term follow-up.
RESUMO
INTRODUCTION AND HYPOTHESIS: Clinical trials for stress urinary incontinence (SUI) require a robust, reliable, and responsive tool for objective assessment of SUI post-intervention. The Aberdeen Home Continence Stress Test (HCST) is a novel patient-reported objective assessment tool, aimed to be patient-friendly and reduce attrition rates by avoiding hospital appointments and prolonged pad-wearing. We aim to describe the HCST for the first time and evaluate its reliability, diagnostic accuracy, and response to change. METHODS: A secondary analysis of the Single-Incision Mini-Slings (SIMS) study (a prospective multicentre randomised control trial (RCT) comparing two surgical treatments of SUI was performed. In SIMS (n = 600 women), the objective outcome was assessed by the 24-h pad test, while the patient-reported success rates were assessed using the Patient Global Impression of Improvement (PGI-I) at 15 months, 2 years and 3 years post-randomisation. Participants were instructed to perform the HCST before and after the 24-h pad test. The HCST was analysed in relation to reliability, validity, and the relationship between the 24-h pad test and HCST results and finally with regard to its responsiveness to change in PGI-I. (Trial registration-number ISRCTN93264234, registration date 14/01/2014). RESULTS: Compared to the 24-h pad test, the sensitivity of the HCST ranged from 0.81-0.95, specificity was 0.76-0.79, negative predictive value was 0.96-0.99 and positive predictive value was 0.32-0.43. Reliability was indicated by high-performing Cronbach's alpha value (> 0.7). An improvement of ≥ 2 leakage groups on the HCST (for example from Large at baseline to Small leakage at follow-up) was strongly associated with patient-reported success on PGI-I (OR 4.38, 95% CI 2.31, 8.31). CONCLUSIONS: The HCST is a valid and reliable patient-reported objective assessment tool that can be used for assessing SUI in surgical trials with good specificity, sensitivity, and consistency.

Background: The COVID-19 pandemic follows severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) coronavirus epidemics. Some survivors of COVID-19 infection experience persistent respiratory symptoms, yet their cause and natural history remain unclear. Follow-up after SARS and MERS may provide a model for predicting the long-term pulmonary consequences of COVID-19. Methods: This systematic review and meta-analysis aims to describe and compare the longitudinal pulmonary function test (PFT) and computed tomography (CT) features of patients recovering from SARS, MERS and COVID-19. Meta-analysis of PFT parameters (DerSimonian and Laird random-effects model) and proportion of CT features (Freeman-Tukey transformation random-effects model) were performed. Findings: Persistent reduction in the diffusing capacity for carbon monoxide following SARS and COVID-19 infection is seen at 6â months follow-up, and 12â months after MERS. Other PFT parameters recover in this time. 6â months after SARS and COVID-19, ground-glass opacity, linear opacities and reticulation persist in over 30% of patients; honeycombing and traction dilatation are reported less often. Severe/critical COVID-19 infection leads to greater CT and PFT abnormality compared to mild/moderate infection. Interpretation: Persistent diffusion defects suggestive of parenchymal lung injury occur after SARS, MERS and COVID-19 infection, but improve over time. After COVID-19 infection, CT features are suggestive of persistent parenchymal lung injury, in keeping with a post-COVID-19 interstitial lung syndrome. It is yet to be determined if this is a regressive or progressive disease.
RESUMO
The use of preoperative urodynamics as a standard investigation for urinary incontinence (UI) has long been a subject of debate, with a lack of robust evidence to demonstrate improved patients' outcomes. We aim to compare the clinical and cost effectiveness of urodynamics versus office clinical evaluation only, prior to the treatment of UI. We conducted three linked systematic reviews and meta-analyses of randomised controlled trials (RCTs) comparing urodynamics assessment versus clinical evaluation only in women prior to 1) non-surgical treatment of UI, 2a) surgical treatment of stress urinary incontinence (SUI) and 2b) invasive treatment for overactive bladder (OAB). Women with severe pelvic organ prolapse, previous continence surgery and neuropathic bladder were excluded. Primary outcomes were patient-reported and objective success post-treatment. Secondary outcomes were adverse events, quality of life, sexual function and health economic measures. We searched MEDLINE, Embase and Cochrane Central Register of Controlled Trials databases for each category, which was last updated on January 2019. Study selection, risk of bias assessment and data extraction were performed independently by two reviewers. The random effects model was used to assess risk ratio and mean difference with 95% confidence interval. Statistical heterogeneity was assessed by I2 statistics and the quality of evidence by the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. Four RCTs compared urodynamics versus clinical evaluation only prior to non-surgical management of UI. Treatment consisted of pelvic floor muscle training, with or without pharmacological therapy. Meta-analysis of 150 women showed no evidence of significant difference in the patient-reported and objective success rates between groups (Pâ¯=â¯0.520, RR: 0.91, 95% Cl 0.69-1.21, I2 = 0% and Pâ¯=â¯0.470, RR:0.87, 95% Cl 0.59-1.28, I2 = n/a, respectively). Seven RCTs were identified for surgical management of SUI. The majority of women underwent mid-urethral tape procedures (retropubic or transobturator approach). Meta-analysis of 1149 women showed no evidence of significant difference in patient-reported (Pâ¯=â¯0.850, RR:1.01, 95% CI 0.88-1.16, I2 = 53%) and objective success between groups (Pâ¯=â¯0.630, RR:1.02, 95% CI 0.95-1.08, I2 = 28%). There was no significant difference in incidence of voiding dysfunction, de novo urgency, and urinary tract infection between groups. No RCTs were identified for invasive management of OAB. In conclusion, limited evidence shows that routine urodynamics prior to non-surgical management of UI or surgical management of SUI is not associated with improved treatment outcomes, when compared to clinical evaluation only. Well-designed clinical trials are needed to evaluate the clinical and cost-effectiveness of routine urodynamics prior to surgical management of SUI and OAB.

INTRODUCTION AND HYPOTHESIS: The Patient Global Impression of Improvement (PGI-I) and International Consultation of Incontinence Questionnaire - Short Form (ICIQ-SF) are validated instruments for the assessment of patient reported outcome measures (PROM) following treatment of stress urinary incontinence (SUI). However, there is a paucity of evidence as to what represents a successful postintervention ICIQ-SF score. To determine the correlation between the postoperative ICIQ-SF scores with the PGI-I outcomes, the latter was considered one of the standard PROM following surgical treatment for SUI. The aim of this study was to determine, and if appropriate validate, an ICIQ-SF cut-off score that can predict a successful PROM as determined by PGI-I. METHODS: Four large datasets yielding 674 ICIQ-SF score/PGI-I outcome data pairs were used in this study for (a) determining and (b) validating the cut-off ICIQ-SF score for a successful PGI-I outcome. Two long-term follow-up datasets were used representing follow-up periods of 3 and 8 years of a randomized controlled trial (RCT) performed between April 2005 and April 2007 in a tertiary urogynaecology centre in Scotland, UK. All patients had urodynamic SUI or mixed urinary incontinence (MUI, with predominant SUI) and were randomized to treatment with either an inside-out or an outside-in transobturator tape (TVT-O or TOT, respectively) as a sole procedure. The datasets yielded 432 ICIQ-SF score/PGI-I outcome data pairs. Successful outcome was defined as "very much improved/much improved" on the PGI-I scale. SPSS v. 22.0 (IBM Corp., Armonk, NY) was used for all statistical analyses. The correlations and cut-off scores generated were then validated on two independent datasets representing the 1-year and 4-year follow-up periods of the multicentre RCT in six units in the UK. The datasets yielded 242 ICIQ-SF score/PGI-I outcome data pairs. All patients had urodynamic SUI or MUI (with predominant SUI) and were randomized to either adjustable single incision minisling (SIMS) or TVT-O. RESULTS: Significant correlations at the 0.01 level (two-tailed) were clearly demonstrated between ICIQ-SF scores at follow up and PGI-I outcomes in terms of success/failure in both the generation and validation datasets. Higher ICIQ-SF scores correlated with a 'poorer' PGI-I score. Using ROC analysis, a postoperative ICIQ-SF score of 6 was validated as approximately 90 % sensitive and 85 % specific for success/failure with a high Cohen's kappa coefficient of 0.83 (95 % CI 0.74 - 0.89). CONCLUSIONS: This two-stage study provided a robust well-validated postoperative ICIQ-SF cut-off score (of 6/21) that is likely to be associated with a patient-reported successful outcome on the PGI-I following surgical treatment with a midurethral sling in women at different stages of follow-up over 1 - 8 years. Such a cut-off score could enable the comparison of results between various studies and serve as a valuable guide for surgeons to counsel patients before and/or after surgical treatment. Our study fills a research gap in providing a way to compare trial results when baseline ICIQ-SF scores are not available.

PURPOSE: To assess the long-term patient-reported outcomes following TO-TVT as a secondary continence procedure in women with recurrent stress urinary incontinence (R-SUI). METHODS: A secondary analysis of the 9-year follow-up of the E-TOT study was performed: 341 women with predominant SUI symptoms were randomised to undergo either Inside-out or Outside-in TO-TVT between April 2005 and April 2007. Forty-six women had R-SUI following previously failed continence surgery at time of randomisation and are the basis of this analysis as a one single cohort. Primary outcome was the patient-reported success rate defined as very/much improved on Patient's Global Impression of Improvement (PGI-I). Secondary outcomes included late adverse events and impact on women's quality of life and sexual function. Statistical analysis was performed using SPSS version 23. RESULTS: Sixty-three per cent completed the 9-year follow-up. The success based on the PGI-I was 62.1% with no significant difference between groups (OR 5.33; 95% CI 1.03, 27.76; p = 0.094). Clinically significant improvement in QoL was found in 84.2%. Adverse events included vaginal erosions (n = 3) and groin pain (n = 2). The small sample size is a limitation in this study; nevertheless, this is one of the largest cohorts reported for women with R-SUI and the first to report the long-term outcomes of TO-TVT as a secondary continence procedure. CONCLUSIONS: TO-TVT operations are associated with good patient-reported success rates (62%) in women with previous failed continence surgery with up to 9-years follow-up. There is a non-significant trend towards better outcomes with the inside-out TO-TVT.

AIMS: To assess the long-term patient reported outcomes following transobturator tension-free vaginal tapes (TO-TVT) in women with urodynamic mixed urinary incontinence (MUI). METHODS: A secondary analysis of the 9-year follow-up of the E-TOT study: 341 women with predominant stress urinary incontinence symptoms were randomized to undergo either inside-out or outside-in TO-TVT between April 2005 and April 2007. Forty-eight women had preoperative urodynamic MUI and were available for 9-year follow-up. Primary outcome was the patient-reported success rate defined as very/much improved on Patient's Global Impression of Improvement PGI-I. Secondary outcomes included impact on women's quality of life, sexual function, overactive bladder symptoms,and late adverse events. Statistical analysis was performed using SPSS v.23. RESULTS: Forty-eight women completed the 9-year follow-up, with adjusted response rate of 63%. The success based on the PGI-I was 64.6% (n = 31), with a further 14.6% (n = 7) who reported "improved." There was no significant difference between groups (OR 1.11; 95%CI 0.33, 3.70; P > 0.999). Clinically significant improvement in quality of life was found in 85.3%. Cure of urgency and UUI was reported by 35% and 41%, whereas worsening was reported in 6.5% and 2.3%, respectively. One patient reported chronic groin/leg pain. The small sample size and the sizeable loss to follow-up are limitations in this study. CONCLUSIONS: This is the first study to report the long-term outcomes of TO-TVT in women with urodynamic MUI; TO-TVT is associated with a good and sustained patient-reported success rate in women with MUI up to 9-years follow-up.

PURPOSE: We evaluate the clinical effectiveness of transobturator tension-free vaginal tape procedures in the surgical management of mixed urinary incontinence in women at 3-year followup. MATERIALS AND METHODS: In this secondary analysis of a prospective, single-blind, randomized controlled trial 83 of 341 women (24%) with mixed urinary incontinence were randomized to undergo an outside-in (Aris® transobturator sling system 42) or inside-out (TVT™-O 41) transobturator tension-free vaginal tape procedure. Patients were contacted by postal questionnaire at a minimum of 3 years postoperatively. The primary outcome was the patient reported success rate, defined as very much improved/much improved on the PGI-I (Patient Global Impression of Improvement). Secondary outcomes included improvement in quality of life, impact on preoperative urgency/urgency incontinence and repeat surgical treatment for stress urinary incontinence. Outcomes at 3 years were compared between groups (outside-in vs inside-out) and to 1-year outcomes. Analysis was performed using SPSS® version 20 with significance levels set at p = 0.05. RESULTS: A total of 66 women with mixed urinary incontinence completed the 3-year followup (outside-in 35 vs inside-out 31). In each group 2 women underwent further continence surgery. The patient reported success rate was 73.8% with no significant differences between the groups (OR 1.035, 95% CI 0.342-3.134, p = 0.951). Overall 34 (50.1%) and 26 women (56.5%) reported cure of preoperative urgency and urgency incontinence, respectively, and 52 women (86.7%) had a clinically significant improvement in quality of life (18 points or more in total KHQ [King's Health Questionnaire] score) compared to baseline. CONCLUSIONS: Transobturator tape procedures are associated with a good (73.8%) patient reported success rate at a minimum of 3 years of followup in the surgical management of mixed urinary incontinence in women with predominant stress urinary incontinence symptoms. Nearly half of the women reported cure of urgency/urgency incontinence.

CONTEXT: An updated systematic review and meta-analysis of randomised controlled trials (RCTs) comparing single-incision mini-slings (SIMS) versus standard midurethral slings (SMUS) in the surgical management of female stress urinary incontinence (SUI). OBJECTIVE: To evaluate the clinical efficacy, safety, and cost effectiveness of SIMS compared with SMUS in the treatment of female SUI. EVIDENCE ACQUISITION: A literature search was performed for all RCTs and quasi-RCTs comparing SIMS with either transobturator tension-free vaginal tape (TO-TVT) or retropubic tension-free vaginal tape (RP-TVT). The literature search had no language restrictions and was last updated on May 2, 2013. The primary outcomes were patient-reported and objective cure rates at 12 to 36 mo follow-up. Secondary outcomes included operative data; peri- and postoperative complications, and repeat continence surgery. Data were analysed using RevMan software. Meta-analyses of TVT-Secur versus SMUS are presented separately as the former was recently withdrawn from clinical practice. EVIDENCE SYNTHESIS: A total of 26 RCTs (n=3308 women) were included. After excluding RCTs evaluating TVT-Secur, there was no evidence of significant differences between SIMS and SMUS in patient-reported cure rates (risk ratio [RR]: 0.94; 95% confidence interval [CI], 0.88-1.00) and objective cure rates (RR: 0.98; 95% CI, 0.94-1.01) at a mean follow-up of 18.6 mo. These results pertained on comparing SIMS versus TO-TVT and RP-TVT separately. SIMS had significantly lower postoperative pain scores (weighted means difference [WMD]: -2.94; 95% CI, -4.16 to -1.73) and earlier return to normal activities and to work (WMD: -5.08; 95% CI, -9.59 to -0.56 and WMD: -7.20; 95% CI, -12.43 to -1.98, respectively). SIMS had a nonsignificant trend towards higher rates of repeat continence surgery (RR: 2.00; 95% CI, 0.93-4.31). CONCLUSIONS: This meta-analysis shows that, excluding TVT-Secur, there was no evidence of significant differences in patient-reported and objective cure between currently used SIMS and SMUS at midterm follow-up while associated with more favourable recovery time. Results should be interpreted with caution due to the heterogeneity of the trials included.

The study aims to explore the potentially influential factors affecting women's decision to accept/decline participation in surgical randomised trial using a novel acceptance/refusal questionnaire (ARQ). All women who were eligible to participate in SIMS-RCT were asked to complete the relevant section (acceptance/refusal) of the ARQ. Women reported its degree of relevance for their decision on a six-point Likert scale (0 = highly irrelevant, 5 = highly relevant). 135 (98%) and 31 (70%) women completed the acceptance and refusal sections of the ARQ, respectively. The most influencing factor in women's acceptance was the anticipation of "potential personal benefit"; percentage of relevance (POR) was 91.9%, followed by interest in helping others by "supporting innovative medical research"; POR was 87.7%. Most influencing factor in refusal for participation was "do not have time for follow-up"; POR was 56.8%, followed by "do not like the concept of randomisation"; POR was 54.4%. In conclusion, this study identifies the most influential factors relevant to women decision-making whether or not to participate in RCTs assessing surgical interventions for female stress urinary incontinence (SUI). A number of factors leading to refusal of participation are potentially correctable leading to better recruitment rates in future RCTs.

OBJECTIVES: To assess the cost, quality of life (QoL) and cost-effectiveness of a single-incision mini-sling (SIMS; Ajust(®) , C. R. Bard Inc., New Providence, NJ, USA) compared with a standard mid-urethral sling (SMUS; TVT-O™, Ethicon Inc., Somerville, NJ, USA) in the surgical management of female stress urinary incontinence. PATIENTS AND METHODS: A total of 137 women, in a secondary care setting, were randomized between October 2009 and October 2011 to undergo SIMS placement (n = 69) under local anaesthesia as an opt-out policy or SMUS placement (n = 68) under general anaesthesia. Clinical outcome measures included the patient-reported success rate (Patient Global Impression of Improvement [PGI-I]) and the impact on the patients' QoL (King's Health Questionnaire [KHQ]). Health economic data (cost and quality-adjusted life year [QALY] data) were compared using linear regression models to generate an incremental cost per QALY estimate, in order to determine a measure of cost-effectiveness. Deterministic sensitivity analyses investigated uncertainty in the results, and non-parametric bootstrapping techniques were used to estimate a probability of cost-effectiveness. RESULTS: There were no significant differences between the groups in terms of the KHQ total score (P = 0.27) or the patient-reported success rate (P = 1.00, odds ratio: 0.895; 95% confidence interval [CI]: 0.344 to 2.330). There was no significant difference in QALYs for the SIMS group compared with the SMUS group (mean difference: -0.003; 95% CI: -0.008 to +0.002). The SIMS was on average less costly, -£142.41 95% CI: (-316.99 to 32.17) and generated cost savings of £48 419 per QALY loss with 94% probability of cost savings to the health services. Taking a wider perspective on the costing analysis by including the wider community benefit associated with the significantly earlier return to work observed in the SIMS group (P = 0.006, 95% CI: 11.756 to 17.217), there was an increase in cost savings to -£477, (95% CI: -823.65 to -129.63), with a probability of 100% of cost savings to the wider economy. CONCLUSIONS: The adjustable anchored SIMS (Ajust), performed under local anaesthesia as an opt-out policy, delivers cost savings to the health service provider when compared with the SMUS (TVT-O), and is likely to be cost-effective up to 1 year after placement. Further research should be undertaken to confirm the results of our study over longer follow-up and should explore patient preferences alongside an adequately powered non-inferiority randomized controlled trial.

OBJECTIVE: To compare an adjustable anchored single incision mini-sling (SIMS-Ajust) vs tension-free vaginal tape-obturator (TVT-O) in the management of female stress urinary incontinence (SUI) with a minimum of 1-year follow-up. METHODS: We conducted a multicenter prospective randomized control trial (RCT) performed in 6 United Kingdom centers in the period between October 2009 and October 2011. Women were randomized to either SIMS-Ajust (C. R. Bard) performed under local anesthesia or TVT-O (Ethicon Inc.) performed under general anesthesia. Women completed validated symptom-severity and quality of life (QOL) questionnaires preoperatively and at 1 year. In addition, women completed the Patient Global Impression of Improvement (PGI-I) and underwent the Cough Stress Test (CST) at 1 year. The primary outcome at 12 months was the patient-reported success rate. Secondary outcomes included objective cure, reoperation rate, impact on women's urinary symptoms, QOL, and sexual function. Data was analyzed using SPSS-19 with significance level set at 5%. RESULTS: One hundred thirty-seven women were randomized into 2 groups: the SIMS-Ajust group (n = 69) and the TVT-O group (n = 68). At 1 year, there were no significant differences in the patient-reported success rate (odds ratio [OR] 0.895, 95% confidence interval [CI] 0.344-2.330, P = 1.000), objectives success rate (OR 0.929, 95% CI 0.382-2.258, P = 1.00), and reoperation rates (OR 0.591, 95% CI 0.136-2.576, P = .721) between the SIMS-Ajust and the TVT-O groups, respectively. A comparable number of women reported cure/improvement of urgency (P = .658), significant improvement in QOL (P = .190), and sexual function (P = .699) in both groups. CONCLUSION: Adjustable-anchored SIMS (Ajust) is associated with comparable patient-reported and objective success rates when compared to standard midurethral sling (SMUS, TVT-O) at a minimum of 1-year follow-up. The results should be interpreted with caution due to the relatively small cohort size. Long-term follow-up of this RCT is required to ascertain the durability of these results.

OBJECTIVES: To compare the postoperative pain profile, peri-operative details, and short-term patient-reported and objective success rates of single-incision mini-slings (SIMS) versus standard mid-urethral slings (SMUS). STUDY DESIGN: In a multicentre prospective randomised trial in six UK centres in the period between October 2009 and October 2010, 137 women were randomised to either adjustable SIMS (Ajust®, C. R. Bard Inc., NJ, USA), performed under local anaesthesia as an opt-out policy (n=69), or SMUS (TVT-O™, Ethicon Inc., Somerville, USA) performed under general anaesthesia (n=68). Randomisation was done through number-allocation software and using telephone randomisation. Postoperative pain profile (primary outcome) was assessed on a ten-point visual analogue scale at fixed time-points. Pre- and post operatively (4-6 months) women completed symptom severity, urgency perception scale (UPS), quality of life and sexual function questionnaires. In addition, women completed a Patient Global Impression of Improvement Questionnaire and underwent a cough stress test at 4-6 months follow up. Sample size calculation was performed and data were analysed using SPSS 18. Descriptive analyses are given and between-group comparisons were performed using chi-square, Fischer exact test and Mann-Whitney test as appropriate. Significance level was set at 5%. RESULTS: Women in the SIMS Ajust® group had a significantly lower postoperative pain profile up to 4 weeks (p=<0.001, 95% CI 1.151, 2.480). There was no significant difference in peri-operative complications between groups. All 137 women completed the 4-6 months follow-up. Patient-reported and objective cure rates were not significantly different: 85.5% versus 91.2% (p=0.443) and 90% versus 97% (p=0.165) between the SIMS Ajust® and TVT-O™ groups respectively. There was a trend towards higher rates of de novo urgency or worsening of pre-existing urgency in the SIMS Ajust® group (21.7% versus 8.8%) but this did not reach statistical significance (p=0.063). Women in the SIMS Ajust® group had shorter hospital stay (median (IQR) 3.65 (2.49, 4.96)) compared to (4.42 (3.16, 5.56)) the TVT-O™ group 95% CI (-0.026, 1.326), with significantly earlier return to normal activities (p=0.025) and to work (p=0.006). CONCLUSION: The adjustable single-incision mini-sling (Ajust®) is associated with a significantly improved postoperative pain profile and earlier return to work when compared to standard mid-urethral slings (TVT-O™), with encouraging results in patient-reported and objective success rates at short-term follow-up.

BACKGROUND: There is a lack of information on the long-term outcomes of transobturator tension-free vaginal tape (TO-TVT) in the surgical treatment of female stress urinary incontinence (SUI). OBJECTIVES: To assess the 3-yr outcomes following TO-TVT and to compare the effectiveness of inside-out versus outside-in approaches. DESIGN, SETTING, AND PARTICIPANTS: A 3-yr follow-up study of the Evaluation of Transobturator Tapes (E-TOT) trial, a randomised controlled trial (RCT) conducted with women undergoing TO-TVT as a sole procedure between April 2005 and April 2007 in a tertiary urogynaecology centre in the United Kingdom. INTERVENTION: Patients (n=341) were randomised to undergo either TVT-O (Ethicon Inc., Somerville, NJ, USA) for the inside-out approach or TOT-Aris (Coloplast Corp., Minneapolis, MN, USA) for the outside-in approach. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was patient-reported success rate. Secondary outcomes included further treatment for SUI, improvement in quality of life, late complications, and risk factors for late failures. Categorical variables were compared using the chi-square or Fisher exact test. Within-group comparison was undertaken using Wilcoxon and Mann-Whitney tests. Risk factors for late failures were assessed in a multivariate regression model. All statistical analysis was performed using SPSS v.18.0 (IBM Corp., Armonk, NY, USA). RESULTS AND LIMITATIONS: The 3-yr follow-up was completed by 238 of the 341 women (70%). The overall success rate, based on Patient's Global Impression of Improvement response, was 73.1%, with no significant difference between the inside-out and the outside-in TO-TVT (73.18% vs 72.3%; odds ratio: 0.927; 95% confidence interval, 0.552-1.645; p=0.796). Compared with the 1-yr follow-up, there was a significant reduction in the patient-reported success rate (p=0.005); however, no independent risk factors were identified. A clinically significant improvement (≥10 points) was seen in 80% (n=191) of women, with no significant difference between both groups (p=0.113). Twenty-two women (6%) underwent further surgical treatment within 3 yr. The lack of an objective outcome assessment is a potential limitation of this RCT. CONCLUSIONS: The E-TOT RCT showed a 73% patient-reported success rate for TO-TVT at 3-yr follow-up, with no significant differences between inside-out and outside-in approaches. There was a significant drop in patient-reported success rates between 1 and 3 yr.

OBJECTIVES: To determine whether an adjustable single-incision mini-sling (SIMS, Ajust(®) ) is safe and effective in the management of female stress urinary incontinence (SUI) at 12 months follow-up. To determine whether it is feasible to be performed under local anesthesia (LA). MATERIALS AND METHODS: The present study is a multicentre prospective cohort study in which 90 female patients underwent SIMS-Ajust(®) using a standardized insertion technique. The last 45 women were offered the procedure under LA. All patients completed their 12-month follow-up. RESULTS: The patient-reported success rate, using Patient Global Impression of Improvement (PGI-I), was 80% at 12 months follow-up and a further 6% (n= 5) reported themselves to be 'improved'. In all, 32/45 (71%) patients agreed to undergo the procedure under LA while one patient required conversion to general anaesthetic. There was no organ damage or requirement for blood transfusion. Significantly lower rates of blood loss (P= 0.025) and postoperative voiding difficulties (P= 0.026) were seen in the LA group. The re-operation rate for SUI was 6% at 12 months. CONCLUSIONS: SIMS (Ajust) appears to be a safe procedure, which is feasible under LA. SIMS (Ajust) have an 80% patient-reported success rate at 12 months follow-up.

OBJECTIVE: To determine whether preoperative urodynamic parameters can predict the development of short-term voiding dysfunction (VD) after a transobturator tension-free vaginal tape (TO-TVT) procedure. METHODS: In a prospective study between April 2005 and April 2007, 341 women were randomized to receive "inside-out" or "outside-in" TO-TVT. The present secondary analysis included women who had completed a preoperative symptom questionnaire, had a voided volume of 100mL or more on preoperative uroflowmetry, and underwent standardized postoperative voiding assessment. VD was defined as a requirement for postoperative catheterization. Univariate and multivariate analysis were done by SPSS 17. RESULTS: The inclusion criteria were met by 224 women, of whom 17 (7.6%) had postoperative VD. On univariate analysis, there were no differences in preoperative parameters among those with and those without VD: residual urine volume (P=0.485), peak flow rate on or below 5th centile (P=0.272), average flow rate on or below 5th centile (P=0.142), detrusor pressure at opening (P=0.955), maximum urethral closure pressure at 30 cm H(2)O or less (P=0.855) and functional urethral length (P=0.173). None of the variables analyzed was an independent risk factor on multivariate analysis. CONCLUSION: Preoperative urodynamic parameters did not predict the development of short-term voiding dysfunction after a TO-TVT procedure.
