Use of digital health tools in inflammatory bowel disease. / Uso de herramientas digitales en salud en enfermedad inflamatoria intestinal.

OBJECTIVE: To analyse the characteristics and use of digital health tools (DHT) in inflammatory bowel disease (IBD). METHODS: We performed a qualitative study based on a narrative literature review, a questionnaire and on the opinion of 3 expert gastroenterologists. Several searches were carried out until September 2022 through Medline to identify articles on the use of DHT in IBD by healthcare professionals. A structured questionnaire was designed to be answered by health professionals involved in the care of patients with IBD. The experts generated a set of recommendations. RESULTS: There are multiple DHT for IBD with different characteristics and contents. We received 29 questionnaires. Almost 50% of the participants were 41-50 years old, the majority were women (83%) and 90% were gastroenterologists. A total of 96% reported the use of several DHT, but 20% used them occasionally or infrequently. Web pages were found the most used (62%). DHT are mostly used to get information (80%), followed by clinical practice issues (70%) and educational purposes (62%). G-Educainflamatoria website is the best known and most used HDS (96% and 64%, respectively). The main barriers to the use of DHT in IBD were the lack of time (55%), doubts about the benefit of DHT (50%) and the excess of information (40%). CONCLUSIONS: Healthcare professionals involved in the care of patients with to IBD frequently use DHT, although actions are needed to optimize their use and to guarantee their efficient and safe use.

Cost-Effectiveness Analysis of Abrocitinib Compared with Other Systemic Treatments for Severe Atopic Dermatitis in Spain.

INTRODUCTION: Atopic dermatitis (AD) is a chronic, inflammatory skin disease characterized by itchy, painful, and dry skin. Despite the great number of available therapies, economic evaluations are still needed to provide evidence on their cost efficiency. This research aimed to evaluate the cost effectiveness of the Janus kinase (JAK) inhibitor abrocitinib (200 mg) compared with dupilumab (300 mg), tralokinumab (300 mg), baricitinib (2 and 4 mg), and upadacitinib (15 and 30 mg) for the treatment of patients with severe AD from the Spanish National Health System (NHS) perspective. METHODS: A hybrid model consisting of a decision tree linked to a Markov model was developed to estimate costs, quality-adjusted life-years (QALYs), total years in response and incremental cost-per-QALY gained (willingness-to-pay [WTP] threshold: €25,000/QALY). Adults with severe AD entered the decision tree and response (75% reduction in baseline Eczema Area and Severity Index score, EASI-75) was considered at 16 and 52 weeks. After this time, patients entered the Markov model (remainder of the 10-year time horizon), which consisted of three health states: maintenance with active therapy, subsequent treatment, or death. All costs were presented in 2022 euros (€). Additionally, cost per number-needed-to-treat (NNT) was calculated for abrocitinib and dupilumab based on a head-to-head post-hoc analysis. RESULTS: Abrocitinib 200 mg was dominant (i.e., lower incremental costs and higher incremental benefit) compared with all studied alternatives (dupilumab 300 mg, tralokinumab 300 mg, baricitinib 2 and 4 mg, upadacitinib 15 and 30 mg) with a QALYs gain of 0.49, 0.60, 0.64, 0.43, 0.45, and 0.08, respectively, and per-person costs savings of €22,097, €24,140, €14,825, €7,116, €12,805, and €45,189, respectively. Considering the WTP threshold, abrocitinib was dominant or cost effective compared with all alternatives for most simulations. Additionally, abrocitinib was dominant compared with all alternatives when evaluating the cost effectiveness over a 5-year time horizon. NNT showed that abrocitinib was dominant versus dupilumab. CONCLUSIONS: The results of the study show that abrocitinib is a cost-effective therapy compared with other JAK inhibitors and biological therapies from the Spanish NHS perspective.

Characteristics and management of patients with stroke and major hemorrhagic episodes with atrial fibrillation under vitamin K antagonist therapy. EVENTHO study

Introduction and objective: In Spain, vitamin K antagonists (VKA) remain the standard treatment for the prevention of thromboembolic and hemorrhagic complications in patients with atrial fibrillation (AF), despite the high risks of suffering adverse effects. The objective of this study was to characterize the profile of VKA-treated patients suffering from stroke/systemic embolism (SE) or major hemorrhagic episodes, their evolution and the actions taken after those episodes.Materials and methodsEVENTHO was an observational multicenter study conducted in 22 Anticoagulation Spanish Units. The study included patients ≥18 years with AF who suffered major hemorrhagic episodes (67.8%) or stroke/SE (32.1%) during 2016 whileon VKA treatment [acenocoumarol (98.2%) or warfarin (1.8%)]. Time in therapeutic range (TTR) was calculated according to the Rosendaal method based on the international normalized ratio (INR) values of the previous 6 months.ResultsThe study included 585 patients (median age [range] 82.3 [43.6–96.2] years; 51.1% men; mean [95% confidence interval, CI] CHA2DS2-VASc: 4.3 [4.2–4.4] and HAS-BLED: 2.2 [2.1–2.3]). Poor anticoagulation and VKA maintenance were higher in patients with major hemorrhagic episode (p<0.0001). The most common situations after hospital discharge were: functional dependence, neurological sequelae and death.ConclusionsIn the sample studied, half of the AF patients who suffered stroke/SE or major hemorrhagic episode had inadequate TTR and, despite this, after hospital discharge, they restarted treatment with VKA. These results highlight the need to evaluate safer and effective therapeutic alternatives in AF patients with poor TTR control after suffering a stroke/SE or major hemorrhagic episode. (AU)

Introducción y objetivo: En España, los antagonistas de la vitamina K (AVK) siguen siendo el tratamiento estándar para la prevención de las complicaciones tromboembólicas y hemorrágicas en pacientes con fibrilación auricular (FA), a pesar del alto riesgo de presentar efectos adversos. El objetivo de este estudio fue caracterizar el perfil de los pacientes tratados con AVK que experimentaron un ictus/embolia sistémica o hemorragia mayor, su evolución y las acciones realizadas tras esos episodios.Materiales y métodosEVENTHO fue un estudio multicéntrico observacional realizado en 22 unidades españolas de anticoagulación. Se incluyó en el estudio a pacientes≥18 años con FA que habían tenido hemorragia mayor (67,8%) o ictus/embolia sistémica (32,1%) durante 2016 y estaban en tratamiento con AVK (acenocumarol [98,2%] o warfarina [1,8%]). El tiempo en rango terapéutico (TRT) se calculó según el método de Rosendaal basado en los valores del índice internacional normalizado de los 6 meses previos.ResultadosEl estudio incluyó a 585 pacientes (edad mediana 82,3 [rango 43,6-96,2] años; 51,1% hombres; CHA2DS2-VASc medio 4,3 [IC 95% 4,2-4,4] y HAS-BLED medio 2,2 [IC 95% 2,1-2,3]). La mala anticoagulación y el mantenimiento de los AVK fueron mayores en los pacientes con hemorragia mayor (p<0,0001). Las situaciones más frecuentes tras el alta hospitalaria fueron: dependencia funcional, secuelas neurológicas y muerte.ConclusionesEn la muestra estudiada, la mitad de los pacientes con FA que tuvieron ictus/embolia sistémica o hemorragia mayor presentaban un TRT inadecuado y, a pesar de ello, tras el alta hospitalaria, reiniciaron el tratamiento con AVK. Estos resultados destacan la necesidad de evaluar alternativas terapéuticas más seguras y eficaces en pacientes con FA con mal control del TRT tras sufrir un ictus/embolia sistémica o hemorragia mayor.

Safety Profile and Tolerability of Topical Phosphodiesterase 4 Inhibitors for the Treatment of Atopic Dermatitis: A Systematic Review and Meta-Analysis.

Objective: Evaluate the safety profile and tolerability of topical phosphodiesterase 4 (PDE4) inhibitors versus vehicle as treatment for atopic dermatitis in published studies. Methods: A search was performed in Medline/PubMed, Web of Science, and Cochrane Library databases on September 27, 2021, by 1 evaluator, without restrictions on publication dates or languages. Terms such as atopic dermatitis, phosphodiesterase 4 inhibitors, calcineurin inhibitors, and randomized controlled trials were included. The database searches were carried out by 1 evaluator. The titles and abstracts were reviewed for the identification and evaluation of potentially eligible studies. Study selection was made by two reviewers, so there was no intra-examiner statistic at the study selection step. The full-text articles were reviewed to determine whether or not they would be included in the systematic review. Global analyses, which included studies with both unclear and low risk of bias and subanalyses of studies with a low risk of bias were performed. Results: Out of 237 identified articles, 14 clinical trials were included in the meta-analysis. In global analyses of studies with low and unclear risk of bias, topical treatment with PDE4 inhibitors did not differ from vehicle treatment in global treatment emergent adverse events (relative risk = 0.99; 95% CI, 0.87-1.14; P = 0.94) or in serious emergent adverse events appearance (relative risk = 0.92; 95% CI, 0.39-2.20; P = 0.86). In subanalyses of studies with a low risk of bias, a reduced rate of atopic dermatitis exacerbation was observed in PDE4 inhibitors compared with the vehicle (relative risk = 0.62; 95% CI, 0.39-0.98; P = 0.04) and risk of pain at the application site was confirmed (relative risk = 2.59; 95% CI, 1.27-5.28; P = 0.01). Conclusions: PDE4 inhibitors did not show differences from vehicle treatment in treatment emergent adverse events or serious emergent adverse events incidence. In studies with low risk of bias, PDE4 inhibitors had a statistically significant risk of producing pain and reduced occurrence of atopic dermatitis exacerbation.

Cost-effectiveness of direct oral anticoagulants compared to low-molecular-weight-heparins for treatment of cancer associated venous thromboembolism in Spain.

AIM: Recent studies have compared the efficacy and safety of direct-acting oral anticoagulants (DOAC) and low-molecular-weight heparin (LMWH) for cancer-associated venous thromboembolism (VTE). However, there is no available cost-effectiveness analysis comparing DOAC and LMWH. The study aimed to conduct a cost-effectiveness analysis of DOAC (apixaban, edoxaban, and rivaroxaban) vs. LMWH for the treatment of cancer-associated VTE in Spain from the Spanish healthcare system perspective. METHODS: We developed a Markov model with a 12-month time horizon. The states included pulmonary embolism, deep vein thrombosis, major and non-major bleeding, chronic thromboembolic pulmonary hypertension, post-thrombotic syndrome, and death. The use of medical resources and drug costs were obtained from the 2021 Spanish Ministry of Health database, and the main references for obtaining the outcomes were derived from Caravaggio, Hokusai VTE Cancer, ADAM VTE, and SELECT-D trials. We performed a deterministic and probabilistic sensitivity analysis to validate the robustness. The Incremental Cost-Effectiveness Ratio (ICER) scores cost per life-year (€/LY) gained and cost per quality-adjusted life-year (€/QALY) gained. RESULTS: The 12-month cost of DOAC was 1,994€ (apixaban 1,944€, edoxaban 1,968€, rivaroxaban 2,122€) and 2,152€ for LMWH. The amount of QALY for DOAC was 0.54 (apixaban 0.55, rivaroxaban 0.53, and edoxaban 0.52) and 0.53 for LMWH. We observed similar results for LYs. ICER scores in terms both of €/LY and €/QALY show that DOAC is dominant over LMWH and apixaban showed the best profile. LIMITATIONS: Our research is based on an indirect comparison of a short-term clinical trial. CONCLUSION: Our results suggest that DOAC is cost-effective and cost-saving compared to LMWH in treating VTE.

Do patient characteristics predict which patients with overactive bladder benefit from a higher fesoterodine dose?

INTRODUCTION AND HYPOTHESIS: We sought to determine whether baseline characteristics predict which overactive bladder (OAB) patients benefit from fesoterodine 8 mg versus 4 mg. METHODS: In double-blind, placebo-controlled, flexible-dose trials, baseline characteristics of OAB patients with ≥ 1 urgency urinary incontinence (UUI) episodes/24 h who escalated from fesoterodine 4 mg to 8 mg were evaluated. Possible dose-escalation predictors (age; sex; previous antimuscarinic use; UUI, micturitions, and urgency episodes/24 h; race; body mass index; time to dose escalation; OAB duration) were compared in escalators versus non-escalators. Patients from fixed-dose trials with dose-escalator characteristics were identified (matched dose-escalator sample) to assess changes from baseline with fesoterodine 4 mg, 8 mg, and placebo. RESULTS: In flexible-dose trials, significant predictors of fesoterodine dose escalation were younger age (≤ 65.8 years), greater number of baseline micturitions (≥ 13.1) and urgency episodes/24 h (≥ 10.9), greater OAB duration (≥ 9.1 years), and more frequent previous antimuscarinic use (58.3%), but not baseline UUI episodes/24 h. In the matched dose-escalator sample (fesoterodine 4 mg: n = 215; 8 mg: n = 198; placebo: n = 217), change from baseline in UUI episodes significantly improved with fesoterodine 8 mg versus 4 mg (P = 0.043) and with both doses versus placebo (P < 0.001). Dry mouth and constipation rates were higher with fesoterodine 8 mg. CONCLUSIONS: Dose-escalator patients had a significantly greater UUI response with fesoterodine 8 mg versus 4 mg. Given the potential for adverse events, fesoterodine 4 mg is recommended to start; however, patients with UUI and identified predictors may benefit from initial treatment with fesoterodine 8 mg or rapid dose escalation.

Characteristics of antimuscarinic responders versus suboptimal responders in a randomized clinical trial of patients with overactive bladder symptoms.

OBJECTIVE: To assess the characteristics of tolterodine extended-release (ER) 4 mg responders and suboptimal responders (≤50% decrease in UUI episodes/24 h) among patients with overactive bladder (OAB), including urgency urinary incontinence (UUI), and identify predictors of a >50% UUI response with fesoterodine 8 mg in tolterodine suboptimal responders. METHODS: Adult patients with OAB symptoms for ≥6 months and ≥8 micturitions, and ≥2 and <15 UUI episodes/24 h at week -2 received open-label tolterodine ER 4 mg during a 2 week run-in. Suboptimal responders after tolterodine treatment (week 0) were randomized to fesoterodine (4 mg for 1 week, 8 mg for weeks 2-12) or placebo once daily. Post-hoc analyses compared the percentage change from week -2 to week 0 in UUI episodes/24 h in tolterodine responders versus suboptimal responders and identified significant predictors of a UUI response at week 12 with fesoterodine 8 mg among tolterodine suboptimal responders. RESULTS: Of 897 patients, 610 (68%) were UUI suboptimal responders during the run-in period. UUI episodes/24 h at week -2 were similar in tolterodine responders and suboptimal responders (4.2 vs. 4.3), but responders showed a significantly greater median percentage decrease in UUI episodes/24 h after tolterodine treatment at week 0 (80.0% versus 15.3%; p < .0001). During double-blind treatment, the percentage of patients with a UUI response at week 12 was significantly greater with fesoterodine (69.9%) than placebo (57.0%; p = .0027). Fesoterodine (vs. placebo), no previous antimuscarinic use before tolterodine run-in, and less UUI severity at baseline were significant predictors of a UUI response. CONCLUSIONS: For patients with OAB, including UUI, who were treated initially with tolterodine and showed a suboptimal UUI response, nearly 70% demonstrated a UUI response with second-line fesoterodine 8 mg. No antimuscarinic use before tolterodine and fewer baseline UUI episodes were significant predictors of a UUI response with fesoterodine.

A pooled analysis of the efficacy of fesoterodine for the treatment of overactive bladder, and the relationship between safety, co-morbidity and polypharmacy in patients aged 65 years or older.

Background: overactive bladder (OAB) is a common condition in older persons. Antimuscarinic treatment remains the mainstay of treatment of OAB but clinicians have been reluctant to prescribe this to older patients. This study examined efficacy and safety information from patients >65 in fesoterodine trials to reaffirm efficacy and to explore the relationships between treatment emergent adverse events (TEAEs), coexisting medication and co-morbidity. Methods: data from 10 double-blind, placebo-controlled studies were analysed. A logistic regression analysis, where TEAE incidence was predicted by treatment, prior antimuscarinic treatment, number of coexisting medications, number of concomitant diseases and all possible combinations of two-way interaction terms with treatment was conducted. Results: of 4,040 patients who participated in trials; fesoterodine treatment was associated with statistically significant reductions in all disease-related and patient-reported outcomes compared to placebo. There was a significant increase in the likelihood of reporting a TEAE in association with the number of coexistent medications (odds ratio (OR) = 1.028, 95% CI: 1.0143-1.044, P < 0.003). The OR of having a TEAE with increase in the number of concomitant diseases was 1.058 (95% CI: 1.044-1.072, P < 0.0001). Central nervous system (CNS) events were few. Discussion: fesoterodine treatment led to clinically meaningful improvements across all included patient reported outcomes. The number of concomitant conditions had the greatest influence on the likelihood of an adverse event being reported. CNS TEAE were not associated with fesoterodine dose and were low across all categories of concomitant disease and coexisting medication.

Perfil del paciente con vejiga hiperactiva tratado con dosis flexible de antimuscarínicos en la práctica clínica diaria / Profile of oab patient on treatment with flexible-dose antimuscarinic drugs in daily clinical practice

OBJETIVO: Describir en el entorno de la práctica clínica diaria, el perfil del paciente con vejiga hiperactiva (VH) tratado con dosis flexible de antimuscarícos. MÉTODOS: Estudio observacional, retrospectivo y multicéntrico llevado a cabo en 88 Hospitales públicos y privados. Se incluyeron pacientes adultos, diagnosticados de VH que iniciaron tratamiento con algún antimuscarínico a dosis flexible. Se recogió tipo de antimuscarínico, dosis, tratamientos concomitantes, beneficio aportado y cumplimiento terapéutico. RESULTADOS: Población constituida por 846 pacientes mayores de 60 años, pluripatológica (83,5%) y polimedicada (73,4%), formada mayoritariamente por mujeres (74,5%) y con más de un año de evolución de la VH. Principales antimuscarínicos inicialmente prescritos: fesoterodina (66,9%) y solifenacina (31,0%). El 68,2% de los pacientes iniciaron el tratamiento con la dosis baja. En la visita de seguimiento, el 47,0% modificó dosis (84,2% aumentaron la dosis, 15,8% disminuyeron la dosis). Los grupos que tuvieron que modificar dosis presentaron significativamente mayor morbilidad, peor sintomatología, mayor empleo de recursos sanitarios y peor cumplimiento terapéutico que el grupo de pacientes tratados siempre a dosis alta. CONCLUSIÓN: En determinados pacientes, el empleo desde el inicio del tratamiento antimuscarínico de dosis- flexible a la dosis más alta, podría proporcionar mayor beneficio terapéutico, adherencia y menor empleo de recursos sanitarios que el escalado de dosis

OBJECTIVE: To describe the profile of the overactive bladder (OAB) patient on treatment with flexible-dose antimuscarinic treatment in daily clinical practice. METHODS: This was an observational, retrospective and multicenter study, carried out at 88 public and private hospitals. Adult patients diagnosed with OAB who initiated flexible-dose antimuscarinic treatment. Type of antimuscarinic, dose, concomitant treatments, treatment benefit and treatment adherence were recorded. RESULTS: This was a pluripathological (83.5%) and polymedicated (73.4%) population, comprised of 846 patients, mostly women (74.5%) with a mean (SD) age of 61.3 (12.1) years and more than one year of OAB evolution. Main initially prescribed antimuscarinics were fesoterodine (66.5%) and solifenacine (30.0%). Overall, 68.2% of the patients started treatment with the low dosage; at the follow-up visit 47.0% changed the dosage (84.2% increased the dosage, 15.8% decreased the dosage). Patients who changed the dosage showed a significantly greater morbidity, worse OAB symptoms, greater health resources use, and worse adherence to treatment compared with those that maintained the high dosage all the time. CONCLUSION: No differences were found regarding the demographic or clinical characteristics that allow us to identify which patients should receive the different options of available dose of antimuscarinic drugs, although greater benefits seem to be achieved with the use of the highest or the lowest dose from the outset than with the change of dose

Development of a predictive model for urgency urinary incontinence.

The ability to set realistic expectations of treatment response in patients with overactive bladder (OAB) can have an impact on patient engagement and adherence to study medication. In order to help set treatment expectations for OAB, a Physician Predictive Tool has been developed based on predictive modelling. Models have been developed utilizing data from eight Phase 3 and 4 fesoterodine clinical trials and these models enable the prediction of individual treatment response in subjects with OAB, based on various baseline characteristics. The data utilized and covariates that were hypothesized to influence treatment response are described. The model selection and development process are also outlined, and the final model and some example results utilizing this model are presented. Finally, we discuss the potential benefits and limitations of such a predictive tool.

Fesoterodine clinical efficacy and safety for the treatment of overactive bladder in relation to patient profiles: a systematic review.

OBJECTIVE: To summarize published evidence on the pharmacology, efficacy, and safety of fesoterodine for the treatment of overactive bladder (OAB) symptoms in relation to patient clinical and demographic profiles. METHODS: A systematic review of published articles on fesoterodine was conducted via a PubMed search. Articles were identified using the search term fesoterodine, with limits of human species and abstract available. Review and meta-analysis articles, validation studies, articles focused on treatment compliance/adherence, meeting abstracts, and articles not focused on oral fesoterodine administration in human subjects were excluded. Data from retained articles were summarized descriptively. RESULTS: Of 137 articles identified, 61 (15 articles on the pharmacology and 46 articles on the efficacy and/or safety of fesoterodine) met inclusion criteria. Superiority trials demonstrated the additional efficacy of fesoterodine 8 mg versus fesoterodine 4 mg and tolterodine extended release 4 mg in treating OAB. Prospective trials in specific patient populations indicated beneficial effects of fesoterodine in elderly patients, vulnerable elderly patients, patients dissatisfied with or with a suboptimal response to previous antimuscarinic therapy, patients with urge urinary incontinence (UUI) or nocturnal urgency, and men with persistent LUTS during alpha-blocker treatment. With two effective doses, the fesoterodine dose can be adjusted to achieve optimal efficacy and tolerability in individual patients. The most common adverse events during fesoterodine treatment are dry mouth and constipation. CONCLUSIONS: Extensive evidence demonstrates the efficacy and safety of fesoterodine in relieving OAB symptoms, including urgency, urinary frequency, UUI, and nocturnal urgency, in patients with various clinical and demographic profiles. Trial results provide valuable information on fesoterodine treatment in specific patient populations, including both elderly and vulnerable elderly patients. Potential limitations of this review are that only English language articles in PubMed were searched and included.

Review of the efficacy and safety of fesoterodine for treating overactive bladder and urgency urinary incontinence in elderly patients.

Overactive bladder (OAB) is a common condition, with prevalence rates increasing with advancing age. Symptoms of OAB, including urgency urinary incontinence (UUI), are associated with various co-morbidities in elderly individuals (e.g., falls and fractures, functional impairment, and depression). The current mainstay of pharmacological therapy for OAB is antimuscarinic agents. Until recently, few studies had specifically evaluated the efficacy and safety of antimuscarinics in the treatment of OAB symptoms in elderly patients. This review summarises available evidence from the medical literature on the efficacy and safety of fesoterodine in elderly patients with OAB symptoms, including UUI. The data from unique placebo-controlled fesoterodine trials of elderly and vulnerable elderly patients, together with age-stratified data from post hoc analyses of fesoterodine trials, demonstrate that treatment with fesoterodine 4 or 8 mg results in statistically and clinically significant improvements in OAB symptoms and patient-reported outcomes in many elderly patients. The data indicate that the efficacy of fesoterodine in elderly patients is comparable with that in younger patients. Fesoterodine is generally well tolerated in elderly and vulnerable elderly patients, with low rates of urinary retention and little evidence of central nervous system events or impaired cognition. The data support a favourable benefit-to-risk ratio for fesoterodine in elderly and medically complex vulnerable elderly patients with OAB.

Factors associated with dose escalation of fesoterodine for treatment of overactive bladder in people >65 years of age: A post hoc analysis of data from the SOFIA study.

AIM: To investigate factors which may influence dose escalation of antimuscarinics for overactive bladder (OAB) in older patients and how dose escalation affects treatment efficacy. MATERIALS AND METHODS: A post hoc analysis of data from the 12-week randomized, placebo controlled phase of the SOFIA study investigating treatment with fesoterodine in older people with OAB. Predictors and outcomes in patients aged ≥65 years with OAB who did or did not choose to escalate from fesoterodine 4 to 8 mg before the first dose-escalation choice point (week 4) and at the end of the study (week 12) were assessed. RESULTS: Variables which significantly increased likelihood of dose escalation were, at baseline, body mass index (OR: 1.06, 95% CI 1.01, 1.12; P = 0.0222), and male gender (OR: 2.06, 95% CI 1.28, 3.32; P = 0.0028) and at week 4, change from baseline in urgency episodes (OR: 1.12, 95% CI 1.05, 1.20; P = 0.0008), patient perception of bladder control (PPBC) (OR: 1.44, 95% CI 1.12, 1.84; P = 0.004). At week 12, dose escalation was associated with slightly reduced treatment outcomes compared to week 4 non-escalators. CONCLUSIONS: No baseline disease related factor associated with dose escalation was identified. Magnitude of change in urgency episodes and reduction in PPBC at 4 weeks were associated with dose escalation. These data may be of use to healthcare providers as they allow judgement to be made in individual patients, allowing treatment decisions to be made. At end of treatment, improvements in efficacy and quality of life were achieved in both escalators and non-escalators.

Validación psicométrica de las escalas OAB-V8 y OAB-V3 para la detección de pacientes con probable vejiga hiperactiva en la población española / Psychometric validation of the OAB-V8 and OAB-V3 scales for the screening of patients with probable overactive bladder in the Spanish population

Fundamento y objetivo: Realizar la validación psicométrica en la población española de la escala Overactive Bladder Awareness Tool (OAB-V8), y de su versión abreviada, OAB-V3, para la detección de pacientes con probable vejiga hiperactiva (VH). Pacientes y método: Estudio transversal en población general > 18 años realizado por vía telemática (Internet) sobre una población representativa de la prevalencia de VH en la población española. Las propiedades evaluadas incluyeron factibilidad, fiabilidad y validez. Los sujetos incluidos fueron clasificados según la probabilidad de VH usando un algoritmo automatizado validado previamente. Se realizó análisis de curvas ROC y se determinaron sensibilidad, especificidad, y valores predictivos positivo y negativo. Resultados: Se incluyeron 2.035 sujetos, con una edad media + DE de 52,7 + 12,1 años (50,8% varones). El 13,7% fue clasificado como «Probable»; el 27,9% como «Posible» y el 58,3% como «No» VH. La consistencia interna para las escalas OAB-V8 y OAB-V3 fue alta (0,894 y 0,851 respectivamente), con correlaciones ítem-total asimismo elevadas en ambos casos (0,87-0,88 y 0,71-0,83 respectivamente). Ambas escalas fueron fiables con coeficientes de correlación intraclase de 0,826 (intervalo de confianza del 95%: 0,695-0,901) y 0,828 (intervalo de confianza del 95%: 0,623-0,922), respectivamente. El punto de corte óptimo en la escala OAB-V8 para identificar probable VH fue ≥ 8 puntos (área bajo la curva 0,895; sensibilidad 0,875 y especificidad 0,735), mientras que en la OAB-V3 fue ≥ 3 (área bajo la curva 0,910, sensibilidad 0,828 y especificidad 0,825). Conclusión: Las escalas OAB-V8 y OAB-V3 resultaron ser herramientas útiles de cribado autoadministrado por vía telemática, factibles, fiables y válidas para la detección de pacientes con probable VH en la población general en España (AU)

Background and objective: To perform the psychometric validation in the Spanish population of the Overactive Bladder Awareness Tool (OAB-V8) scale and its abbreviated version OAB-V3 for screening patients with probable overactive bladder (OAB). Patients and methods: A cross-sectional study was conducted in a population aged over 18 years, which was representative of the prevalence of OAB in Spain using an online methodology (Internet survey). Psychometric properties included feasibility, reliability, and validity. Subjects were classified according to the likelihood of OAB, using an automated algorithm validated previously. ROC curve analysis was performed, and the sensitivity, specificity, and positive and negative predictive values were also assessed. Results: A total of 2,035 subjects with a mean + SD age of 52.7 + 12.1 years were included (50.8%) men. In total 13.7% were classified as «Probable», 27.9% «Possible», and 58.3% «No» OAB. The internal consistency of both OAB-V8 and OAB-V3 scales was high (0.894 and 0.851, respectively). The item-total correlation coefficients were high; 0.87-0.88 and 0.71-0.83, respectively. Intraclass correlation coefficient for OAB-V8 was 0.826 (confidence interval 95% 0.695-0.901) and it was 0.828 (confidence interval 0.623-0.922) for OAB-V3. The optimum cut-off value of OAB-V8 for detecting probable OAB was ≥ 8 points (AUC = 0.895, sensitivity 0.875, specificity 0.735), while for the OAB-V3 it was ≥ 3 (AUC = 0.910, sensitivity 0.828, specificity 0.825). Conclusion: Both OAB-V8 and OAB-V3 scales were considered useful online self-administered screening tools, which were also feasible, reliable and valid for the detection of patients with probable OAB in the general population in Spain (AU)

Effects of drug cessation after flexible-dose fesoterodine in patients with overactive bladder.

OBJECTIVE: To determine the course of overactive bladder (OAB) symptoms after 4 weeks of no treatment following a 12-week study of the efficacy and safety of flexible-dose fesoterodine in patients with OAB who were enrolled in the UK healthcare system. There are limited data available on the natural time course of OAB symptoms after the cessation of treatment. PATIENTS AND METHODS: In the open-label UK Study Assessing Flexible-dose Fesoterodine in Adults trial, patients aged ≥18 years with self-reported OAB symptoms for ≥3 months, a mean of at least eight micturitions per 24 h and three or more urgency episodes per 24 h on a 3-day bladder diary at baseline, and at least moderate bladder-related problems reported on the Patient Perception of Bladder Condition (PPBC) at baseline, were treated with fesoterodine for 12 weeks. All patients received fesoterodine 4 mg once daily for the first 4 weeks, at which time they could choose to increase the dose to 8 mg once daily, based on a discussion of treatment efficacy and tolerability with the investigator, or they could remain on fesoterodine 4 mg for the remaining 8 weeks. The 12-week treatment period was followed by a 4-week follow-up period of no fesoterodine treatment. Patients completed 3-day bladder diaries and the PPBC at baseline, week 4, end of treatment (week 12) and end of the follow-up period (week 16); the King's Health Questionnaire at baseline, end of treatment (week 12) and end of the follow-up period (week 16); and the Benefit, Satisfaction and Willingness to Continue questionnaire at week 12. RESULTS: After 12 weeks of fesoterodine treatment, patients had clinically meaningful improvements in bladder diary variables and King's Health Questionnaire domains; 79% (254/322) of patients reported an improvement on the PPBC. After 4 weeks of no treatment, most patients deteriorated back to week 4 levels or worse on all bladder diary and patient-reported outcomes. Patients who expressed a benefit from fesoterodine treatment, satisfaction with their treatment or a willingness to continue treatment showed greater improvement from baseline to week 12 and greater deterioration from week 12 to week 16 than patients who did not respond positively on the Benefit, Satisfaction and Willingness to Continue questionnaire. Both men and women showed a meaningful deterioration in bladder diary variables and patient-reported outcomes at week 16; baseline symptom severity, age and week 4 dose escalation status did not appear to affect outcome deterioration at week 16. CONCLUSIONS: At 4 weeks after fesoterodine was discontinued, patients showed an increase in the frequency of OAB symptoms, an increase in the severity of bladder-related problems and a reduction in health-related quality of life. Many patients with OAB who respond to antimuscarinics may require treatment for more than 12 weeks because symptoms recur as early as 4 weeks after the cessation of therapy.

Predicting self-perceived antimuscarinic therapy effectiveness on overactive bladder symptoms using the Overactive Bladder 8-Question Awareness Tool.

INTRODUCTION AND HYPOTHESIS: This work was designed to explore the ability of the self-administered Overactive Bladder 8-Question Awareness Tool (OAB-V8) to predict patient self-assessed effectiveness of antimuscarinic therapy on OAB symptoms in daily practice. Also, the ability of the tool to predict clinician evaluation of improvement was explored. METHODS: Patients of both genders, >18 years, with symptomatic OAB (score >8 on OAB-V8), and able to understand patient-reported outcome instruments were enrolled in this 3-month study. Patients were prescribed treatment with an antimuscarinic drug according to usual practice. Treatment effectiveness was assessed by the clinician and patient using the Clinical Global Impression of Improvement and Treatment Benefit Scale and by improved self-perceived quality of life using the Overactive Bladder Questionnaire Short Form (OAB-q SF) 3 months after initiating or changing an antimuscarinic therapy. Multivariate linear and logistic regression models were applied to explore the predictive validity of OAB-V8 scores at the baseline visit. RESULTS: A total of 246 patients (57.7 years, 67 % women) were analyzed. Based on baseline OAB-V8 scores, logistic regression models were capable of predicting clinical improvement and patient self-perceived treatment benefit in 70 % of cases. OAB-V8 scores significantly correlated with OAB-q SF domains at baseline: 0.790 and - 0.659 for symptom bother and health-related quality of life domains, respectively (p < 0.001 in both cases). Baseline OAB-V8 score was able to predict changes in both domains of the OAB-q SF: R (2) = 0.212 and 0.162 for symptom bother and health-related quality of life, respectively. CONCLUSIONS: The OAB-V8 scale showed evidence of predictive validity for antimuscarinic effectiveness in daily practice based on physician assessment and patient self-assessment of improved quality of life and treatment benefit.

Dose and aging effect on patients reported treatment benefit switching from the first overactive bladder therapy with tolterodine ER to fesoterodine: post-hoc analysis from an observational and retrospective study.

BACKGROUND: Previous randomized studies have demonstrated that fesoterodine significantly improves the Overactive Bladder (OAB) symptoms and their assessment by patients compared with tolterodine extended-release (ER). This study aimed to assess the effect of aging and dose escalation on patient-reported treatment benefit, after changing their first Overactive Bladder (OAB) therapy with tolterodine-ER to fesoterodine in daily clinical practice. METHODS: A post-hoc analysis of data from a retrospective, cross-sectional and observational study was performed in a cohort of 748 OAB adults patients (OAB-V8 score ≥8), who switched to fesoterodine from their first tolterodine-ER-based therapy within the 3-4 months before study visit. Effect of fesoterodine doses (4 mg vs. 8 mg) and patient age (<65 yr vs. ≥65 yr) were assessed. Patient reported treatment benefit [Treatment Benefit Scale (TBS)] and physician assessment of improvement with change [Clinical Global Impression of Improvement subscale (CGI-I)] were recorded. Treatment satisfaction, degree of worry, bother and interference with daily living activities due to urinary symptoms were also assessed. RESULTS: Improvements were not affected by age. Fesoterodine 8 mg vs. 4 mg provides significant improvements in terms of treatment benefit [TBS 97.1% vs. 88.4%, p < 0.001; CGI-I 95.8% vs. 90.8% p < 0.05)], degree of worry, bother and interference with daily-living activities related to OAB symptoms (p <0.05). CONCLUSIONS: A change from tolterodine ER therapy to fesoterodine with dose escalation to 8 mg in symptomatic OAB patients, seems to be associated with greater improvement in terms of both patient-reported-treatment benefit and clinical global impression of change. Improvement was not affected by age.
