An Economic Evaluation of a Web-Based Management Support System for Children With Urinary Incontinence: The eADVICE Trial

PURPOSE

Children who require specialist outpatient care typically wait substantial periods during which their condition may progress, making treatment more difficult and costly. Timely and effective therapy during this period may reduce the need for lengthy specialist care. This study evaluated the cost-effectiveness of an individualized, evidence-informed, web-based program for children with urinary incontinence awaiting a specialist appointment (Electronic Advice and Diagnosis Via the Internet following Computerized Evaluation [eADVICE]) compared to usual care. eADVICE was supervised by a primary physician and delivered by an embodied conversational agent.

MATERIALS AND METHODS

A trial-based cost-effectiveness analysis was performed from the perspective of the health care funder as a substudy of eADVICE, a multicenter, waitlist-controlled, randomized trial. Outcomes measures were incremental cost per incremental change in continence status and quality of life on an intention-to-treat basis. Uncertainty was examined using cost-effectiveness planes, scenarios, and 1-way sensitivity analyses. Costs were valued in 2021 Australian dollars.

RESULTS

The use of eADVICE was found to be cost saving and beneficial (dominant) over usual care, with a higher proportion of children dry over 14 days at 6 months (risk difference 0.13; 95%CI 0.02-0.23, P = .03) and mean health care costs reduced by $188 (95%CI $61-$315) per participant.

CONCLUSIONS

An individualized, evidence-informed, web-based program delivered by an embodied conversational agent is likely cost saving for children with urinary incontinence awaiting a specialist appointment. The potential economic impact of such a program is favorable and substantial, and may be transferable to outpatient clinic settings for other chronic health conditions.

Cost-effectiveness of behavioral and pelvic floor muscle therapy combined with midurethral sling surgery vs surgery alone among women with mixed urinary incontinence: results of the Effects of Surgical Treatment Enhanced With Exercise for Mixed Urinary Incontinence randomized trial

BACKGROUND

Urinary incontinence is prevalent among women, and it has a substantial economic impact. Mixed urinary incontinence, with both stress and urgency urinary incontinence symptoms, has a greater adverse impact on quality of life and is more complex to treat than either stress or urgency urinary incontinence alone. Studies evaluating the cost-effectiveness of treating both the stress and urgency urinary incontinence components simultaneously are lacking.

OBJECTIVE

Cost-effectiveness was assessed between perioperative behavioral and pelvic floor muscle therapies combined with midurethral sling surgery and midurethral sling surgery alone for the treatment of women with mixed urinary incontinence. The impact of baseline severe urgency urinary incontinence symptoms on cost-effectiveness was assessed.

STUDY DESIGN

This prospective economic evaluation was performed concurrently with the Effects of Surgical Treatment Enhanced with Exercise for Mixed Urinary Incontinence randomized trial that was conducted from October 2013 to April 2016. Participants included 480 women with moderate-to-severe stress and urgency urinary incontinence symptoms and at least 1 stress urinary incontinence episode and 1 urgency urinary incontinence episode on a 3-day bladder diary. The primary within-trial analysis was from the healthcare sector and societal perspectives, with a 1-year time horizon. Costs were in 2019 US dollars. Effectiveness was measured in quality-adjusted life-years and reductions in urinary incontinence episodes per day. Incremental cost-effectiveness ratios of combined treatment vs midurethral sling surgery alone were calculated, and cost-effectiveness acceptability curves were generated. Analysis was performed for the overall study population and subgroup of women with Urogenital Distress Inventory irritative scores of ≥50th percentile.

RESULTS

The costs for combined treatment were higher than the cost for midurethral sling surgery alone from both the healthcare sector perspective ($5100 [95% confidence interval, $5000-$5190] vs $4470 [95% confidence interval, $4330-$4620]; P<.01) and the societal perspective ($9260 [95% confidence interval, $8590-$9940] vs $8090 [95% confidence interval, $7630-$8560]; P<.01). There was no difference between combined treatment and midurethral sling surgery alone in quality-adjusted life-years (0.87 [95% confidence interval, 0.86-0.89] vs 0.87 [95% confidence interval, 0.86-0.89]; P=.90) or mean reduction in urinary incontinence episodes per day (-4.76 [95% confidence interval, -4.51 to 5.00] vs -4.50 [95% confidence interval, -4.25 to 4.75]; P=.13). When evaluating the overall study population, from both the healthcare sector and societal perspectives, midurethral sling surgery alone was superior to combined treatment. The probability that combined treatment is cost-effective compared with midurethral sling surgery alone is ≤28% from the healthcare sector and ≤19% from the societal perspectives for a willingness-to-pay value of ≤$150,000 per quality-adjusted life-years. For women with baseline Urogenital Distress Inventory irritative scores of ≥50th percentile, combined treatment was cost-effective compared with midurethral sling surgery alone from both the healthcare sector and societal perspectives. The probability that combined treatment is cost-effective compared with midurethral sling surgery alone for this subgroup is ≥90% from both the healthcare sector and societal perspectives, at a willingness-to-pay value of ≥$150,000 per quality-adjusted life-years.

CONCLUSION

Overall, perioperative behavioral and pelvic floor muscle therapies combined with midurethral sling surgery was not cost-effective compared with midurethral sling surgery alone for the treatment of women with mixed urinary incontinence. However, combined treatment was of good value compared with midurethral sling surgery alone for women with baseline severe urgency urinary incontinence symptoms.

ELECtric Tibial nerve stimulation to Reduce Incontinence in Care homes: protocol for the ELECTRIC randomised trial

BACKGROUND

Urinary incontinence (UI) is highly prevalent in nursing and residential care homes (CHs) and profoundly impacts on residents' dignity and quality of life. CHs predominantly use absorbent pads to contain UI rather than actively treat the condition. Transcutaneous posterior tibial nerve stimulation (TPTNS) is a non-invasive, safe and low-cost intervention with demonstrated effectiveness for reducing UI in adults. However, the effectiveness of TPTNS to treat UI in older adults living in CHs is not known. The ELECTRIC trial aims to establish if a programme of TPTNS is a clinically effective treatment for UI in CH residents and investigate the associated costs and consequences.

METHODS

This is a pragmatic, multicentre, placebo-controlled, randomised parallel-group trial comparing the effectiveness of TPTNS (target n = 250) with sham stimulation (target n = 250) in reducing volume of UI in CH residents. CH residents (men and women) with self- or staff-reported UI of more than once per week are eligible to take part, including those with cognitive impairment. Outcomes will be measured at 6, 12 and 18 weeks post randomisation using the following measures: 24-h Pad Weight Tests, post void residual urine (bladder scans), Patient Perception of Bladder Condition, Minnesota Toileting Skills Questionnaire and Dementia Quality of Life. Economic evaluation based on a bespoke Resource Use Questionnaire will assess the costs of providing a programme of TPTNS. A concurrent process evaluation will investigate fidelity to the intervention and influencing factors, and qualitative interviews will explore the experiences of TPTNS from the perspective of CH residents, family members, CH staff and managers.

DISCUSSION

TPTNS is a non-invasive intervention that has demonstrated effectiveness in reducing UI in adults. The ELECTRIC trial will involve CH staff delivering TPTNS to residents and establish whether TPTNS is more effective than sham stimulation for reducing the volume of UI in CH residents. Should TPTNS be shown to be an effective and acceptable treatment for UI in older adults in CHs, it will provide a safe, low-cost and dignified alternative to the current standard approach of containment and medication.

Evaluating the impact of a 'virtual clinic' on patient experience, personal and provider costs of care in urinary incontinence: A randomised controlled trial

OBJECTIVE

To evaluate the impact of using a 'virtual clinic' on patient experience and cost in the care of women with urinary incontinence.

MATERIALS AND METHODS

Women, aged > 18 years referred to a urogynaecology unit were randomised to either (1) A Standard Clinic or (2) A Virtual Clinic. Both groups completed a validated, web-based interactive, patient-reported outome measure (ePAQ-Pelvic Floor), in advance of their appointment followed by either a telephone consultation (Virtual Clinic) or face-to-face consultation (Standard Care). The primary outcome was the mean 'short-term outcome scale' score on the Patient Experience Questionnaire (PEQ). Secondary Outcome Measures included the other domains of the PEQ (Communications, Emotions and Barriers), Client Satisfaction Questionnaire (CSQ), Short-Form 12 (SF-12), personal, societal and NHS costs.

RESULTS

195 women were randomised: 98 received the intervention and 97 received standard care. The primary outcome showed a non-significant difference between the two study arms. No significant differences were also observed on the CSQ and SF-12. However, the intervention group showed significantly higher PEQ domain scores for Communications, Emotions and Barriers (including following adjustment for age and parity). Whilst standard care was overall more cost-effective, this was minimal (£38.04). The virtual clinic also significantly reduced consultation time (10.94 minutes, compared with a mean duration of 25.9 minutes respectively) and consultation costs compared to usual care (£31.75 versus £72.17 respectively), thus presenting potential cost-savings in out-patient management.

CONCLUSIONS

The virtual clinical had no impact on the short-term dimension of the PEQ and overall was not as cost-effective as standard care, due to greater clinic re-attendances in this group. In the virtual clinic group, consultation times were briefer, communication experience was enhanced and personal costs lower. For medical conditions of a sensitive or intimate nature, a virtual clinic has potential to support patients to communicate with health professionals about their condition.

[Incidence of incontinence after radical prostatectomy using claims-based data]

OBJECTIVE

To determine the effect of radical prostatectomy (RP) hospital volume on the probability of post-RP incontinence.

DESIGN

Retrospective research based on claims-based data of health insurers.

METHOD

For every patient with RP the probability of incontinence was determined, based on the definition of claims of one or more incontinence pads per day. Casemix corrections were made based on indicators available in claims-data: age, lymph node dissection, and radiotherapy. No casemix corrections could be made for tumour stage and surgical technique.

RESULTS

A total of 1590 patients were included in this study; for 26.0% of these patients, an average of one or more incontinence pads per day were claimed for. A significant relation between the volume of RP per hospital and the claims of incontinence material was observed. The probability of incontinence was significantly lower in hospitals with a volume of more than 100 RP patients per year when compared to hospitals with less than 100 RP patients per year.

CONCLUSION

The probability of post-RP incontinence decreases as hospitals conduct more RP procedures. The casemix factors included in the analysis only had a limited impact on this observation.

Testing and Treating Women after Unsuccessful Conservative Treatments for Overactive Bladder or Mixed Urinary Incontinence: A Model-Based Economic Evaluation Based on the BUS Study

Objective

To compare the cost-effectiveness of bladder ultrasonography, clinical history, and urodynamic testing in guiding treatment decisions in a secondary care setting for women failing first line conservative treatment for overactive bladder or urgency-predominant mixed urinary incontinence.

Design

Model-based economic evaluation from a UK National Health Service (NHS) perspective using data from the Bladder Ultrasound Study (BUS) and secondary sources.

Methods

Cost-effectiveness analysis using a decision tree and a 5-year time horizon based on the outcomes of cost per woman successfully treated and cost per Quality-Adjusted Life-Year (QALY). Deterministic and probabilistic sensitivity analyses, and a value of information analysis are also undertaken.

Results

Bladder ultrasonography is more costly and less effective test-treat strategy than clinical history and urodynamics. Treatment on the basis of clinical history alone has an incremental cost-effectiveness ratio (ICER) of £491,100 per woman successfully treated and an ICER of £60,200 per QALY compared with the treatment of all women on the basis of urodynamics. Restricting the use of urodynamics to women with a clinical history of mixed urinary incontinence only is the optimal test-treat strategy on cost-effectiveness grounds with ICERs of £19,500 per woman successfully treated and £12,700 per QALY compared with the treatment of all women based upon urodynamics. Conclusions remained robust to sensitivity analyses, but subject to large uncertainties.

Conclusions

Treatment based upon urodynamics can be seen as a cost-effective strategy, and particularly when targeted at women with clinical history of mixed urinary incontinence only. Further research is needed to resolve current decision uncertainty.

[Economic importance of postoperative urinary incontinence]

In the 22,160 patients treated in Germany for prostate cancer by prostatectomy, the costs for direct and indirect sequelae as the result of postoperative urinary incontinence are estimated to be 71.8 million €. This greatly exceeds the costs of 69.8 million € for the operation itself. This additional economic burden can, however, be decisively influenced by using a surgical technique that preserves the integrity of the urethral sphincter.

Cost-effectiveness of a behavioral intervention for persistent urinary incontinence in prostate cancer patients

OBJECTIVE

The aim of this study was to evaluate the cost-effectiveness of a behavioral intervention for urinary incontinence of prostate cancer patients. Study subjects were either participating in or eligible but declined (i.e., nonparticipating) the active intervention study.

METHODS

The intervention-participating subjects were randomized into three groups, including two intervention groups (support and telephone groups) and a usual care reference group. Intervention-nonparticipating subjects were concurrently enrolled. Intervention effectiveness was assessed on the EQ-5D measure. The costs included direct healthcare cost from medical billing data, patient out-of-pocket expense, caregiver expense, patient loss-of-work cost, and intervention cost. We calculated incremental cost-effectiveness ratios (ICERs) from societal, provider, and patient perspectives.

RESULTS

Two hundred and sixty-seven intervention-participating and 69 intervention-nonparticipating post-cancer treatment patients were included. The support and telephone groups, but not the usual care group, had significantly higher EQ-5D index scores (0.054, p = 0.033, and 0.057, p = 0.026, respectively) than the intervention-nonparticipating group at month 6. Within 6 months, intervention cost per subject was $252 and $484, respectively, for providers, and $564 and $203, respectively, for the support and phone group subjects. The final ICERs were $16,759 per quality-adjusted life year (QALY) and $12,561/QALY for support and telephone groups, compared with those of the intervention-nonparticipating group. These ICERs are much smaller than $50,000/QALY, the consensus threshold to determine cost-effectiveness for society.

CONCLUSIONS

The study interventions are cost-effective in consideration of eligible patients who declined the interventions. The interventions can provide meaningful outcome improvement on urinary continence at a low cost. This evidence provides critical information for future health policy decision-making of healthcare providers and payers.

Cost-effectiveness analysis of onabotulinumtoxinA (BOTOX(®)) for the management of urinary incontinence in adults with neurogenic detrusor overactivity: a UK perspective

OBJECTIVES

To evaluate the cost effectiveness of onabotulinumtoxinA (BOTOX(®), 200 units [200 U]) for the management of urinary incontinence (UI) in adults with neurogenic detrusor overactivity (NDO) due to subcervical spinal cord injury or multiple sclerosis that is not adequately managed with anticholinergic drugs (ACHDs).

PERSPECTIVE

UK National Health Service (NHS) perspective.

METHODS

A Markov state-transition model was developed, which compared onabotulinumtoxinA + best supportive care (BSC) with BSC alone (comprising behavioural therapy and pads, alone or in combination with clean intermittent catheterization and possibly with ACHDs). Non-responders were eligible for invasive procedures. Health states were defined according to the reduction in UI episodes. Efficacy data and estimates of resource utilization were pooled from 468 patients on onabotulinumtoxinA in two phase III clinical trials. Drug costs (2013) and administration costs (NHS Reference Costs 2011-2012) were obtained from published sources. The time horizon of the model was 5 years, and costs and benefits were discounted at 3.5%. Scenario, one-way and probabilistic sensitivity analyses (PSAs) were conducted to explore uncertainties around the assumptions.

RESULTS

In the base case, treatment with onabotulinumtoxinA + BSC over 5 years was associated with an increase in costs of £1,689 and an increase in quality-adjusted life-years (QALYs) of 0.4, compared with BSC alone, resulting in an incremental cost-effectiveness ratio of £3,850 per QALY gained. Sensitivity analyses showed that utility values had the greatest influence on model results. PSA suggests that onabotulinumtoxinA + BSC had a 100 % probability of being cost effective at a willingness to pay of <£20,000.

CONCLUSION

For adult patients with NDO who are not adequately managed with ACHDs, onabotulinumtoxinA + BSC appears to be a cost-effective use of resources in the UK NHS.

Cost-effectiveness analysis of solifenacin versus oxybutynin immediate-release in the treatment of patients with overactive bladder in the United Kingdom

OBJECTIVE

To carry out a cost-utility analysis comparing initial treatment with solifenacin 5 mg/day vs oxybutynin immediate-release (IR) 15 mg/day for the treatment of patients with overactive bladder (OAB) from the perspective of the U.K. National Health Service (NHS).

METHODS

A Markov model with six health states was developed to follow a cohort of OAB patients treated with either solifenacin or oxybutynin during a 1-year period. Costs and utilities were accumulated as patients transited through the health states in the model and a drop-out state. Some of the solifenacin patients were titrated from 5 mg to 10 mg/day at 8 weeks. A proportion of drop-out patients were assumed to continue treatment with tolterodine ER. Utility values were obtained from a Swedish study and pad use was based on a multinational clinical trial. Adherence rates for individual treatments were derived from a U.K. database study. For pad use and utility values, the drop-out state was split between those patients who were no longer receiving treatment and those on second-line therapy. Patients on second-line therapy who drop-out were referred for a specialist visit. Results were expressed in terms of incremental cost-utility ratios.

RESULTS

Total annual costs for solifenacin and oxybutynin were £504.30 and £364.19, respectively. First-line drug use represents 49% and 4% of costs and pad use represent 23% and 40% of costs for solifenacin and oxybutynin, respectively. Differences between cumulative utilities were small but were greater for solifenacin (0.7020 vs. 0.6907). The baseline incremental cost-effectiveness ratio was £12,309/QALY.

CONCLUSION

Under the baseline assumptions, solifenacin would appear to be cost-effective with an incremental cost-utility of less than £20,000/QALY. However, small differences in utility between the alternatives and the large number of drop-outs means that the results are sensitive to small adjustments in the values of utilities assigned to the drop-out state.

A randomized controlled trial to assess the efficacy and cost-effectiveness of urinary catheters with silver alloy coating in spinal cord injured patients: trial protocol

BACKGROUND

Patients with non-acute spinal cord injury that carry indwelling urinary catheters have an increased risk of urinary tract infection (UTIs). Antiseptic Silver Alloy-Coated Silicone Urinary Catheters seems to be a promising intervention to reduce UTIs; however, actual evidence cannot be extrapolated to spinal cord injured patients. The aim of this trial is to make a comparison between the use of antiseptic silver alloy-coated silicone urinary catheters and the use of standard urinary catheters in spinal cord injured patients to prevent UTIs.

METHODS/DESIGN

The study will consist in an open, randomized, multicentre, and parallel clinical trial with blinded assessment. The study will include 742 spinal cord injured patients who require at least seven days of urethral catheterization as a method of bladder voiding. Participants will be online centrally randomized and allocated to one of the two study arms (silver alloy-coated or standard catheters). Catheters will be used for a maximum period of 30 days or removed earlier if the clinician considers it necessary. The main outcome will be the incidence of UTIs by the time of catheter removal or at day 30 after catheterization, the event that occurs first. Intention-to-treat analysis will be performed, as well as a primary analysis of all patients.

DISCUSSION

The aim of this study is to assess whether silver alloy-coated silicone urinary catheters improve ITUs in spinal cord injured patients. ESCALE is intended to be the first study to evaluate the efficacy of the silver alloy-coated catheters in spinal cord injured patients.

Violence against women with chronic maternal disabilities in rural Bangladesh

This study explored violence against women with chronic maternal disabilities in rural Bangladesh. During November 2006-July 2008, in-depth interviews were conducted with 17 rural Bangladeshi women suffering from uterine prolapse, stress incontinence, or fistula. Results of interviews showed that exposure to emotional abuse was almost universal, and most women were sexually abused. The common triggers for violence were the inability of the woman to perform household chores and to satisfy her husband's sexual demands. Misconceptions relating to the causes of these disabilities and the inability of the affected women to fulfill gender role expectations fostered stigma. Emotional and sexual violence increased their vulnerability, highlighting the lack of life options outside marriage and silencing most of them into accepting the violence. Initiatives need to be developed to address misperceptions regarding the causes of such disabilities and, in the long-term, create economic opportunities for reducing the dependence of women on marriage and men and transform the society to overcome rigid gender norms.

Urinary incontinence in adults: nurses' beliefs, education and role in continence promotion. A narrative review

INTRODUCTION

Urinary incontinence (UI) has a high prevalence worldwide, in both genders; the available data suggest that the number of incontinent people will dramatically increase in the next few years. The costs generated by UI are similar to those induced by HIV and breast cancer. We aimed to investigate nurses' beliefs, knowledge and educational situation in the field of urinary continence.

METHODS

We performed a narrative review of literature, by searching qualitative and qualitative studies (2006-11) in PubMed, CINAHL and the Cochrane Library. Papers investigating pharmacological and/or surgical intervention were excluded. Only studies referred to adults have been taken into consideration.

RESULTS

Prevalence ranges from 25 to 45% in women; in men, post-prostatectomy UI occurs in a median of 10-15% of the total cases. Benign prostatic hyperplasia, which affects 50% of men aged 50 to 60, is often associated with urge incontinence. The yearly individual expense for pads in Italy has been estimated to be as high as 913 euros in 2004. People often do not know about the possible solutions to UI; nurses seem to lack education in continence promotion, notwithstanding the proven effectiveness of the conservative interventions they could perform in autonomy. In Italy, few academic programs offer nursing education in this field.

CONCLUSIONS

Urinary incontinence seems to be an underestimated problem; nurses often lack proper education in continence promotion. Academic, structured courses would be a solution; however, since education itself is not sufficient to really improve clinical practice, organizational support would be required to effectively promote continence in the broadest possible population. This would be a long-term investment for both quality of care and costs. Further studies are needed, regarding conservative management of UI; research could lead to a strong integration between clinical and academic branches of nursing, resulting in good quality evidence for clinical practice.

Systematic review of the management of incontinence and promotion of continence in older people in care homes: descriptive studies with urinary incontinence as primary focus

AIM

This is a review of descriptive studies with incontinence as the primary focus in older people in care homes.

BACKGROUND

Incontinence is prevalent among residents of care home populations.

DATA SOURCES

MEDLINE and CINAHL were searched from 1996 to 2007 using the highly sensitive search strings of the Cochrane Incontinence Review Group for urinary and faecal incontinence including all research designs. Search strings were modified to enhance selectiveness for care homes and older people and exclude studies involving surgical or pharmacological interventions. Searching of reference sections from identified studies was also used to supplement electronic searches. The Cochrane Library was searched for relevant systematic reviews to locate relevant studies from those included or excluded from reviews. The search was limited to English-language publications.

METHODS

A systematic review of studies on the management of incontinence, promotion of continence or maintenance of continence in care homes was conducted in 2007-2009. This is a report of descriptive studies. Results. Ten studies were identified that reported on prevalence and incidence of incontinence (urinary with or without faecal), policies, assessment, documentation, management or economic evaluation of its management. Use of incontinence pads and toileting programmes comprised the most common management approaches used. No studies were identified that attempted to maintain continence of residents in care homes.

CONCLUSIONS

Studies on maintaining continence and identifying components of toileting programmes that are successful in managing or preventing incontinence and promoting continence in residents of care home populations along with their economic evaluation are warranted.

Redesigning a continence prescription service to improve patient safety and experience

A review of prescribing practice for continence related products revealed shortcomings in the service that patients were receiving. This led to it being radically redesigned, with the continence service being responsible for prescriptions. The new service model also includes telephone triage before prescriptions are issued. Patient feedback on the new model has been extremely positive. This project won the 2009 Nursing Times continence award.

Economic impact of tension-free vaginal tape surgery for urinary incontinence in an ambulatory regimen compared with hospital admission

OBJECTIVES

To determine the cost per patient of a tension-free vaginal tape procedure involving major ambulatory surgery (MAS) compared with inpatient surgery in 2002 and 2003, and to analyse the medical care given following each procedure in a public hospital in Spain.

MATERIAL AND METHODS

The method used was activity-based costing, which involves designing a protocol of processes of caring for the patient with the help of professionals and subsequently calculating the cost of each process; this system was applied retrospectively to patients cared for in 2002 and 2003. In addition, the clinical histories of these patients were reviewed in order to evaluate complementary care given by the emergency service and admissions to hospital immediately following surgery. The relation between these events and each sample group was analysed by means of a non-parametric test and CIs for a 95% level of significance were obtained in order to make the calculations more robust.

RESULTS

The mean cost for the patients in the ambulatory group was 42.43% lower than that for the hospitalized patients. Whereas 5.5% of the ambulatory patients subsequently required admission and a further 7.3% required complementary medical care, 19.2% of the patients who had been hospitalized for the surgery required complementary medical care and 1.4% were readmitted after intervention. In spite of these results, there was no dependence between these variables according to the chi(2) test.

CONCLUSION

MAS produced better results in terms of minimizing costs; under our conditions it was less costly but was of equal efficacy to the surgical intervention.

The cost of urinary incontinence

It has been estimated that 13 million Americans have suffered from urinary incontinence (UI). Costs associated with UI include not only those pertaining to direct treatment, but they include costs related to the indirect psychosocial effects of the condition as well. This article will review both direct and indirect costs of UI and how urologic nurses can assist patients with UI in their overall plan of care.

Solifenacin in the treatment of overactive bladder syndrome in Italian patients: pharmacoeconomic evaluation

OBJECTIVE

To investigate the pharmacoeconomic performance of treatment with solifenacin, a new antimuscarinic with selectivity for the bladder, when compared to tolterodine and placebo, in Italian patients with overactive bladder (OAB).

METHODS

The evaluation was performed using a Markov model. The time horizon of the simulation was 52 weeks, with 1-week cycles. The model simulated outcomes and costs of the treatment with solifenacin (5 mg/day), tolterodine ER (4 mg/day) and no treatment in a cohort representative of the Italian population with OAB. The analysis was conducted mainly from the perspective of the patient, since drugs for the treatment of OAB are not included in the Italian reimbursement list. A supplementary scenario explored the consequences of a hypothetical reimbursement decision by the Italian Health Service to reimburse half of the current retail price in incontinent and responding OAB patients only.

RESULTS

Both treatments produced a reduction in symptoms and improvement in patients' quality of life, with an cost increase of about euro 540-640/patient/year with solifenacin and euro 680-780/patient/year with tolterodine. In a cost/utility analysis, solifenacin dominated tolterodine as it resulted in both more effective and less costly treatment; the cost/utility ratio with respect to no treatment was in the range euro 7,600-18,600/Quality-adjusted life year. The overall expenditure of the hypothesised reimbursement decision was estimated to be about 23 million euros, with a cost/utility ratio of about euro 600-2,400/Quality-adjusted life year, indicating an efficient allocation of health resources.

CONCLUSIONS

While both tolterodine and solifenacin appear to be cost/effective in Italy, the latter has proven to be superior.
