Patient reported outcomes: The ICIQ and the state of the art

Translation and validation into Brazilian Portuguese of the English version of the International Consultation on Incontinence Modular Questionnaire for Male Lower Urinary Tract Symptoms (ICIQ-MLUTS)

OBJECTIVES

To translate and cross-culturally adapt the English version of the International Consultation on Incontinence Modular Questionnaire for Male Lower Urinary Tract Symptoms (ICIQ-MLUTS) into Brazilian Portuguese and evaluate its psychometric properties.

INTRODUCTION

Male lower urinary tract symptoms (LUTS) are frequent and commonly assessed with questionnaires. The ICIQ-MLUTS is a robust instrument that investigates the main aspects of LUTS in men and their impact on quality of life. Although highly recommended, Grade A is not as popular as the International Prostate Symptom Score (IPSS) and remained untranslated and unvalidated for Brazilian Portuguese.

METHODS

After authorization by the Advisory Board of the International Consultation on Incontinence (ICIQ) the translation process was conducted according to the standard guidelines and the ICIQ validation protocol. Internal consistency was assessed using Cronbach's ⍺ coefficient and values > 0.7 were considered satisfactory. To assess test-retest reliability and reproducibility, Spearman's correlation coefficient and intraclass correlation coefficient were used. For group data, a Spearman correlation coefficient or an intraclass correlation coefficient of at least 0.70 demonstrates good test-retest reliability. A p < 0.05 was considered significant.

RESULTS

One hundred and eighty-six, aged 61.41 ± 11.01 years, suffering from LUTS participated in the study between January 2021 and October 2022. Cronbach's ⍺, 0.875, demonstrated the internal consistency of the Portuguese version of ICIQ-MLUTS. The intraclass correlation coefficient of 0.912 (0.882; 0.935 - 95% CI) for the test-retest evidenced the stability and validity of the instrument. Likewise, Spearman's correlation coefficient highlighted the agreement between IPSS and ICIQ-MLUTS, 0.906, <0.001.

DISCUSSION

The Portuguese version of the ICIQ-MLUTS demonstrated internal consistency, stability, and validity, in addition to agreement with the IPSS.

CONCLUSION

The ICIQ-MLUTS, translated and validated into Brazilian Portuguese, is a robust and reliable instrument to assess LUTS in Brazilian men and can be used in the evaluation of treatment and research.

International Urogynecology Consultation: Patient Reported Outcome Measures (PROs) use in the evaluation of patients with pelvic organ prolapse

INTRODUCTION AND HYPOTHESIS

Patient-reported outcome measure instruments include patient-reported outcomes (PROs) and patient-reported goals (PRGs), which allow practitioners to measure symptoms and determine outcomes of treatment that matter to patients.

METHODS

This is a structured review completed by the International Urogynecology Consultation (IUC), sponsored by the International Urogynecological Association (IUGA). The aim of this working group was to evaluate and synthesize the existing evidence for PROs and PRGs in the initial clinical work-up/evaluation and research arena for patients with pelvic organ prolapse (POP).

RESULTS

The initial search generated 3589 non-duplicated studies. After abstract review by 4 authors, 211 full texts were assessed for eligibility by 2 writing group members, and 199 studies were reviewed in detail. Any disagreements on abstract or full-text articles were resolved by a third reviewer or during video meetings as a group. The list of POP PROs and information on PRGs was developed from these articles. Tables were generated to describe the validation of each PRO and to provide currently available, validated translations.

CONCLUSIONS

All patients presenting for POP should be evaluated for vaginal, bladder, bowel and sexual symptoms including their goals for symptom treatment. This screening can be facilitated by a validated PRO; however, most PROs provide more information than needed to provide clinical care and were designed for research purposes.

Quality of life and functional outcomes after transanal total mesorectal excision for rectal cancer-results from the implementation period in Denmark

BACKGROUND

The standard operation for mid- and low rectal cancer total mesorectal excision (TME) is routinely performed as minimally invasive surgery. TME is associated with temporary or permanent functional impairment of pelvic organs, causing reduced quality of life (QoL). Concerns have been raised that the newest minimally invasive approach, transanal TME (TaTME), may further reduce urogenital and anorectal functions.

OBJECTIVE

To determine if functional outcomes affecting QoL are altered after TaTME. Primary end-point is the impact of TaTME on QoL and functional outcomes. Secondary end-point is assessing differences in QoL and functional outcomes after TME surgery from below (TaTME) or above (transabdominal TME).

DESIGN, SETTING, AND PARTICIPANTS

Observational study consisting of prospectively registered self-reported questionnaire data collected at baseline and follow-ups after TaTME. All patients who underwent TaTME during the Danish national implementation phase were included. Central surveillance of the implementation included questionnaires concerning QoL and functional outcomes. Analyses of functional results from the Danish cohort of the ROLARR trial (Jayne et al. in JAMA 318:1569-1580, (2017) are reported separately for perspective, representing the transabdominal approach to TME, i.e., laparoscopic- or robotic-assisted TME (LaTME/RoTME). Applied questionnaires include EORTC QLQ-C30, SF-36, LARS, ICIQ-MLUTS, ICIQ-FLUTS, IPSS, IIEF, SVQ, and FSFI.

RESULTS

A total of 115 TaTME procedures were registered August 2016 to April 2019. LaTME/RoTME patients (n = 92) were operated on January 2011 to September 2014. A temporary postoperative decrease of QoL (global health status and functional scales) was observed, yet long-term results were unaffected by surgery in both groups. In TaTME patients, the anorectal dysfunction increased significantly (p < 0.001) from preoperative baseline to 13.5 months follow-up, where 67.5% (n = 52) reported major LARS symptoms. Urinary function was not significantly impaired after TME regardless of technique. The paucity of responses concerning sexual function precludes conclusions.

CONCLUSIONS

Although an initial reduction in QoL after TME occurs, it normalizes within the first year postoperatively. In concurrence with international results, we found that significant anorectal dysfunction is common after TaTME. No data on anorectal function was available for LaTME/RoTME patients for comparison. We found no indications that transanal TME is inferior to transabdominal TME surgery concerning urogenital functions or health-related QoL.

The Virtue quadratic male sling for postradical prostatectomy urinary incontinence: 3-Year outcome measurements and a predictive model of surgical outcome from a European prospective observational study

AIMS

This prospective multicenter observational study evaluated postprostatectomy incontinence treatment outcomes with Virtue male sling at 12 and 36 months.

METHODS

Objective assessment was based on a 24-h pad weight test with improvement defined by a decrease >50% and cure by less than 1.3 g. Subjective assessment was based on the patient global impression of improvement and International Consultation on Incontinence Questionnaire-urinary incontinence-short form (ICIQ-UI-SF) questionnaires. Subgroups were analyzed by baseline severity of incontinence on a 24-h-pad test, body mass index (BMI), and pads usage. Factors associated with treatment response were assessed using logistic regression at Months 36. Complications were reported.

RESULTS

We analyzed data from 117 men. Objective and subjective improvement were achieved in 54% and 35% and 51% and 34% at 12 and 36 months, respectively. Twenty-one percent and 19% were considered cured, respectively, at 12 and 36 months. No differences per baseline incontinence severity, BMI and pads usage were found at 36 months. Mean ICIQ-UI-SF score decreased from 15 to 9. Predictive factors were BMI, postvoid residual urine, number of nighttime urination, and ICIQ total score. Seven Clavien-Dindo Grade III (5.1%) including four Virtue sling revisions were reported. The most frequent Grade II complications were overactive bladder symptoms and pain reported in 10.3% and 2.9%, respectively. No complications required explantation.

CONCLUSIONS

Virtue male sling is safe and effective in males with mild to severe postprostatectomy urinary incontinence over 36 months. Virtue could be considered an interesting option for postradical prostatectomy urinary incontinence with positive results over time even in patients with high BMI. The predictive model should be validated by further studies.

The International Consultation on Incontinence Questionnaires (ICIQ): An update on status and direction

AIMS

In its 22nd year, the International Consultation on Incontinence Questionnaire (ICIQ) project continues to promote its primary objective; the development and dissemination of patient completed questionnaires for the standardized, high-quality assessment of urinary, bowel, and vaginal symptoms. The paper gives an update on the ICIQ in the context of current scientific developments of PROM design and regulatory requirements, and plans are outlined for its future direction.

METHODS

An online library of all questionnaires, including over 300 translations has been launched to facilitate access through a semi-automated registration system. The ICIQ project continues to update its protocol to meet current scientific standards and incorporate methodological advances within PROM development.

RESULTS

Nineteen psychometrically validated patient-reported outcome measures (PROMs) are published for use in clinical practice and research, including amongst others, a bladder diary, male and female lower urinary tract symptoms, long term catheter, pad use, and bowel symptom questionnaires. The original ICIQ-UI Short Form for the assessment of urinary incontinence continues to be the most internationally used questionnaire and has been translated into over 60 languages. New questionnaires which are under development include the ICIQ-Underactive Bladder and ICIQ-Satisfaction. We anticipate the new website and online library will further facilitate the ease of dissemination and availability of the questionnaires for clinical practice and research.

CONCLUSION

The ICIQ continues to successfully achieve its primary objective. Going forward, a greater focus on promoting routine clinical use and the potential for electronic integration into databases and medical records is envisaged.

Laparoscopic bilateral groin hernia repair with one large self-fixating mesh: prospective observational study with patient-reported outcome of urological symptoms and EuraHS-QoL scores

BACKGROUND

Laparoscopic bilateral inguinal hernia repair may be completed with one large self-fixating mesh crossing the midline. No studies have investigated in detail whether preperitoneal mesh placement induces temporary or more lasting urinary symptoms.

METHODS

Urinary and hernia-related symptoms were evaluated preoperatively and postoperatively at 1, 3 and 12 months using the ICIQ-MLUTS questionnaire and EuraHS-QoL score in patients undergoing bilateral inguinal hernia repair.

RESULTS

One hundred patients were included. Voiding symptoms and bother scores were unchanged at 1 or 3 months, but there was significant improvement at 12 months compared with preoperative findings (symptoms P < 0.001; bother score P < 0.01). Incontinence symptoms improved at 1 month (P < 0.05) but not at 3 or 12 months, with a bother score significantly improved at 1 month (P < 0.01) and 12 months (P < 0.01). Diurnal and nocturnal frequency did not change significantly postoperatively, but 12 months nocturnal bother score was decreased (P < 0.05). EuraHS-QoL scores showed statistical significant improvement in all three domains for all measurements at the different follow-up moments compared to previous measurements. Postoperative symptoms were improved at 12 months, compared with preoperative pain scores (- 6.1), restriction of activity (- 10.1) and cosmetic scores (- 4.7) These findings were statistically significant (P < 0.001). At 12 months, there were no patients with severe discomfort (score ≥ 5) for any of the three domains. No recurrences were diagnosed with 95% clinical follow-up at 12 months.

CONCLUSION

Laparoscopic bilateral groin hernia repair with one large preperitoneal self-fixating mesh did not cause new urinary symptoms and demonstrated significant improvement in voiding symptoms at 12 months. Incontinence and nocturnal bother score were significantly improved.

Validation of a 3 day electronic bladder diary as an app for smart-phone

AIM

To validate an electronic 3-day bladder diary (BD) as an easy-to-use app for smart-phone (eDM3d).

METHODS

Descriptive and cross-sectional prospective study. One hundred and thirty-six patients with overactive bladder syndrome (OABs) or nocturia who had a smart-phone and attended the urology clinics of a tertiary hospital from June to November 2017 were included. Patients filled the eDM3d (test) and the Spanish validated paper BD (DM3d) and questionnaires ICIQ-UISF and BASQ during the first week. Two weeks later, they repeated the eDM3d (retest). We assessed feasibility of the eDM3d (percentage of variables completed), test-retest reliability (qualitative variables: McNemar test; quantitative variables: ICC), paper-app correlation (qualitative variables: Kappa index; quantitative variables: ICC) and convergent validity (correlation between eDM3d and questionnaires, Spearman's rank test). Patients answered a question about satisfaction: "If you had to repeat a BD again, would you choose paper or the app version?"

RESULTS

One hundred and twenty-three (90.4%) participants completed all the variables of the first eDM3d. There were no significant differences in the proportion of patients classified as positive for each symptom between test and retest. ICC ranged from 0.73 to 0.94 for all variables (P < 0.001) in the test-retest assessment. Paper-app correlation was good to excellent for all variables (ICC 0.76-0.95, P < 0.001; Kappa index 0.56-0.84, P < 0.001). Correlation between the eDM3d and the questionnaires ranged from 0.23 to 0.6 (P < 0.01). 120 (88.2%) patients would choose the eDM3d if they had to repeat a BD.

CONCLUSION

The eDM3d presents suitable feasibility, reliability, and validity to assess patients with OABs or nocturia who have a smart-phone.

Acupuncture for management of lower urinary tract symptoms in Parkinson's disease: A protocol for the systematic review of randomized controlled trials

BACKGROUND

Acupuncture is claimed to improve the lower urinary tract symptoms (LUTS). Currently, no systematic reviews are performed for acupuncture on LUTS in patients with Parkinson's diseases (PD). This review aims to evaluate the current evidence on the efficacy of acupuncture for the management of LUTS in PD.

METHODS AND ANALYSES

Eleven databases will be searched from their inception. These include PubMed, AMED, EMBASE, the Cochrane Library, 6 Korean medical databases, and 1 Chinese medical database. Study selection, data extraction, and assessment will be performed independently by 2 researchers. Risk of bias will be assessed with the Cochrane risk of bias assessment tool.

ETHICS AND DISSEMINATION

Ethical approval will not be required, given that this protocol is for a systematic review. The systematic review will be published in a peer-reviewed journal and disseminated both electronically and in print. The review will be updated to inform and guide healthcare practice and policy.

Effect of pulsed magnetic stimulation on quality of life of female patients with stress urinary incontinence: an IDEAL-D stage 2b study

INTRODUCTION AND HYPOTHESIS

We evaluated the effects of pulsed magnetic stimulation (PMS) on overall and different aspects of quality of life (QoL) in female patients with stress urinary incontinence (SUI).

METHODS

This study involved 120 female SUI subjects aged ≥21 years old randomized to either active or sham PMS. Treatment involved two PMS sessions per week for 2 months (16 sessions). After 2 months, subjects could opt for 16 additional sessions regardless of initial randomization. The primary response criterion was a 7-point reduction in the total score of the International Consultation on Incontinence Questionnaire-Lower Urinary Tract Symptoms Quality of Life (ICIQ-LUTSqol) questionnaire. Follow-ups were conducted at months 1, 2, 5, 8, and 14.

RESULTS

At 2 months, 35 out of 60 (58%) subjects in the active arm and 21 out of 60 (21%) in the sham arm were treatment responders (≥7-point reduction) (p = 0.006). There was a significant difference in changes in the mean ± SE ICIQ-LUTSqol total score between the active and sham arms (M_diff = -8.74 ± 1.25 vs -4.10 ± 1.08, p = 0.006). At 1-year post-treatment, regardless of number of PMS sessions (16 or 32 sessions), subjects who received active PMS (63 out of 94, 67%) were more likely to be treatment responders compared with subjects who did not receive any active PMS (3 out of 12, 25%; p < 0.001). The impact of PMS treatment was the greatest on the "physical activities" domain.

CONCLUSIONS

PMS resulted in significant short- and long-term improvements in overall and various physical, social, and psychological aspects of QoL.

Mobile App for Treatment of Stress Urinary Incontinence: A Cost-Effectiveness Analysis

BACKGROUND

Mobile apps can increase access to care, facilitate self-management, and improve adherence to treatment. Stress urinary incontinence (SUI) affects 10-35% of women and, currently, an app with instructions for pelvic floor muscle training (PFMT) is available as first-line treatment. A previous randomized controlled study demonstrated that the app benefitted symptom severity and quality of life (QoL); in this study we investigate the cost-effectiveness of the app.

OBJECTIVE

The objective of this study was to evaluate the health economy of the app for treating SUI.

METHODS

This deterministic cost-utility analysis, with a 1-year societal perspective, compared the app treatment with no treatment. Health economic data were collected alongside a randomized controlled trial performed in Sweden from March 2013 to October 2014. This study included 123 community-dwelling women participants of 18 years and above, with stress urinary incontinence ≥1 time per week. Participants were self-assessed with validated questionnaires and 2-day leakage diaries, and then randomized to 3 months of treatment (app group, n=62) or no treatment (controls, n=61). The app focused on pelvic floor muscle training, prescribed 3 times daily. We continuously registered treatment delivery costs. Data were collected on each participant's training time, incontinence aids, and laundry at baseline and at a 3-month follow-up. We measured quality of life with the International Consultation on Incontinence Modular Questionnaire on Lower Urinary Tract Symptoms and Quality of Life, and calculated the quality-adjusted life years (QALYs) gained. Data from the 3-month follow-up were extrapolated to 1 year for the calculations. Our main outcome was the incremental cost-effectiveness ratios compared between app and control groups. One-way and multiway sensitivity analyses were performed.

RESULTS

The mean age of participants was 44.7 years (SD 9.4). Annual costs were €547.0 for the app group and €482.4 for the control group. Annual gains in quality-adjusted life years for app and control groups were 0.0101 and 0.0016, respectively. Compared with controls, the extra cost per quality-adjusted life year for the app group ranged from -€2425.7 to €14,870.6, which indicated greater gains in quality-adjusted life years at similar or slightly higher cost.

CONCLUSIONS

The app for treating stress urinary incontinence is a new, cost-effective, first-line treatment with potential for increasing access to care in a sustainable way for this patient group.

Reliability and Validity of the Persian Language Version of the International Consultation on Incontinence Questionnaire - Male Lower Urinary Tract Symptoms (ICIQ-MLUTS)

OBJECTIVES

Assessment instruments are essential for research, allowing diagnosis and evaluating treatment outcomes in subjects with lower urinary tract disorders of both genders. The purpose of this study was to translate the Male Lower Urinary Tract Symptoms (MLUTS) Questionnaire and determine its psychometric properties in Persian subjects.

METHODS

After getting permission from the International Consultation on Incontinence Modular Questionnaire (ICIQ) web site, the forward and backward translation of the MLUTS questionnaire were carried out by researcher team. The content/face validity, construct validity and reliability were assessed in a sample of MLUTS Iranian patients by measuring with the Cronbach's alpha test.

RESULTS

In total, 121 male patients were included in the study. The mean age of the patients was 60.5 years. Cronbach alpha value was 0.757, consecrated the internal consistency of the form (r > 0.7). The internal consistency of each question was examined separately and found to be over 0.7. For the evaluation of reliability test-retest was done, the test was administered to 20% of the patients for a second time with an interval of 1-2 weeks. The intraclass correlation coefficient (ICC) score was 0.901. The Correlation coefficient between the MLUTS and International Prostate Symptoms Score (IPSS) was 0.879.

CONCLUSIONS

ICIQ-MLUTS is a robust instrument, which can be used for evaluating male LUTS in Persian patients. We believe that the Persian version of the MLUTS is an important tool for research and clinical setting.

A pilot study on the use of acupuncture or pelvic floor muscle training for mixed urinary incontinence

Objectives

To determine the feasibility and acceptability of traditional Chinese medicine (TCM) acupuncture and pelvic floor muscle training (PFMT) in reducing symptoms and bothersomeness in women with mixed urinary incontinence (MUI); and to estimate the sample size for a full scale trial.

Methods

Thirty-four women with MUI were randomly assigned to either 12 sessions of TCM acupuncture, 12 sessions of PFMT, or to a waiting list control group. Outcome measures included an assessment of interest to participate in the trial, identification of successful recruitment strategies, the appropriateness of eligibility criteria, and compliance with treatment. Clinical outcomes were assessed at baseline and 12 weeks, and included the International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form (ICIQ-UI SF), expectations of treatment effect, and adverse events.

Results

Recruitment was feasible and randomisation worked adequately by means of SurveyMonkey. SurveyMonkey does not permit stratification by ICIQ-UI SF baseline score. Fourteen of 22 women found the treatment options acceptable. The dropout rate was high, especially in the control group (6/12). Outcome forms were completed by 20 of 34 women. The median (IQR) changes of the ICIQ-UI SF scores in the acupuncture, physiotherapy, and waiting list group were 5.5 (2.3 to 6.8), 1.0 (−3.0 to 4.5), and 1.5 (−1.5 to 3.0), respectively, suggesting the need for a full scale trial.

Conclusions

Women with MUI were willing to participate in this study. There is a need for adjusting eligibility criteria. A sample size of 129 women, 43 in three arms, is required. No major adverse events occurred.

Internet-based treatment of stress urinary incontinence: 1- and 2-year results of a randomized controlled trial with a focus on pelvic floor muscle training

Objectives

To evaluate the long-term effects of two non-face-to-face treatment programmes for stress urinary incontinence (SUI) based on pelvic floor muscle training (PFMT).

Subjects and Methods

The present study was a randomized controlled trial with online recruitment of 250 community-dwelling women aged 18–70 years with SUI ≥ one time/week. Diagnosis was based on validated self-assessed questionnaires, 2-day bladder diary and telephone interview with a urotherapist. Consecutive computer-generated block randomization was carried out with allocation by an independent administrator to 3 months of treatment with either an internet-based treatment programme (n = 124) or a programme sent by post (n = 126). Both interventions focused mainly on PFMT. The internet group received continuous e-mail support from a urotherapist, whereas the postal group trained on their own. Follow-up was performed after 1 and 2 years via self-assessed postal questionnaires. The primary outcomes were symptom severity (International Consultation on Incontinence Questionnaire Short Form [ICIQ-UI SF]) and condition-specific quality of life (ICIQ-Lower Urinary Tract Symptoms Quality of Life [ICIQ-LUTSqol]). Secondary outcomes were the Patient Global Impression of Improvement, health-specific quality of life (EQ-visual analogue scale [EQ-VAS]), use of incontinence aids, and satisfaction with treatment. There was no face-to-face contact with the participants at any time. Analysis was based on intention-to-treat.

Results

We lost 32.4% (81/250) of participants to follow-up after 1 year and 38.0% (95/250) after 2 years. With both interventions, we observed highly significant (P < 0.001) improvements with large effect sizes (>0.8) for symptoms and condition-specific quality of life (QoL) after 1 and 2 years, respectively. No significant differences were found between the groups. The mean (sd) changes in symptom score were 3.7 (3.3) for the internet group and 3.2 (3.4) for the postal group (P = 0.47) after 1 year, and 3.6 (3.5) for the internet group and 3.4 (3.3) for the postal group (P = 0.79) after 2 years. The mean changes (sd) in condition-specific QoL were 5.5 (6.5) for the internet group and 4.7 the for postal group (6.5) (P = 0.55) after 1 year, and 6.4 (6.0) for the internet group and 4.8 (7.6) for the postal group (P = 0.28) after 2 years. The proportions of participants perceiving they were much or very much improved were similar in both intervention groups after 1 year (internet, 31.9% [28/88]; postal, 33.8% [27/80], P = 0.82), but after 2 years significantly more participants in the internet group reported this degree of improvement (39.2% [29/74] vs 23.8% [19/80], P = 0.03). Health-specific QoL improved significantly in the internet group after 2 years (mean change in EQ-VAS, 3.8 [11.4], P = 0.005). We found no other significant improvements in this measure. At 1 year after treatment, 69.8% (60/86) of participants in the internet group and 60.5% (46/76) of participants in the postal group reported that they were still satisfied with the treatment result. After 2 years, the proportions were 64.9% (48/74) and 58.2% (46/79), respectively.

Conclusion

Non-face-to-face treatment of SUI with PFMT provides significant and clinically relevant improvements in symptoms and condition-specific QoL at 1 and 2 years after treatment.

Cost-effectiveness of an Internet-based treatment program for stress urinary incontinence

AIMS

To perform a deterministic cost-utility analysis, from a 1-year societal perspective, of two treatment programs for stress urinary incontinence (SUI) without face-to-face contact: one Internet-based and one sent by post. The treatments were compared with each other and with no treatment.

METHODS

We performed this economic evaluation alongside a randomized controlled trial. The study included 250 women aged 18-70, with SUI ≥ 1 time/week, who were randomized to 3 months of pelvic floor muscle training via either an Internet-based program including e-mail support from an urotherapist (n = 124) or a program sent by post (n = 126). Recruitment was web-based, and participants were self-assessed with validated questionnaires and 2-day bladder diaries, supplemented by a telephone interview with a urotherapist. Treatment costs were continuously registered. Data on participants' time for training, incontinence aids, and laundry were collected at baseline, 4 months, and 1 year. We also measured quality of life with the condition-specific questionnaire ICIQ-LUTSqol, and calculated the quality-adjusted life-years (QALYs) gained. Baseline data remained unchanged for the no treatment option. Sensitivity analysis was performed.

RESULTS

Compared to the postal program, the extra cost per QALY for the Internet-based program ranged from 200€ to 7,253€, indicating greater QALY-gains at similar or slightly higher costs. Compared to no treatment, the extra cost per QALY for the Internet-based program ranged from 10,022€ to 38,921€, indicating greater QALY-gains at higher, but probably acceptable costs.

CONCLUSION

An Internet-based treatment for SUI is a new, cost-effective treatment alternative.

Bladder and bowel symptoms among adults presenting with low back pain to an academic chiropractic clinic: results of a preliminary study

OBJECTIVE

The purposes of this study were to estimate the 1-month point prevalence of bowel and bladder symptoms (BBS) among adult chiropractic patients and to evaluate associations between these symptoms and low back pain (LBP).

METHODS

Patients 18 years or older presenting to a chiropractic college academic health clinic between March 25 and April 25, 2013, were asked to complete a symptom screening questionnaire. Descriptive statistics, binary logistic regression, Fisher exact test, and P values were calculated from the sample.

RESULTS

The sample included 140 of 1300 patients who visited the clinic during the survey period (11%). Mean age was 47.5 (range 18-79) years. LBP was the primary chief complaint in 42%. The 1-month point prevalence of any bladder symptoms was 75%, while the rate for bowel symptoms was 62%; 55% reported both BBS. Binary logistic regression analyses showed no statistically significant association between a chief complaint of LBP and combined BBS (OR = 1.67, P = .164).

CONCLUSION

The prevalence of bowel and bladder symptoms in chiropractic patients was high. There was no statistically significant association between these symptoms and LBP in this group of patients seeking care for LBP.

Is there an urban-rural-gradient in patients with urinary incontinence?

INTRODUCTION

The objective of this study was to determine whether the responses to the same questionnaire differ between women living in a large city and women living in a rural area.

METHODS

We evaluated the medical records of 88 patients living in the large city of Cologne and of 86 patients living in Brühl and its surrounding rural regions. The responses on the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) of 88 patients who suffer from urinary incontinence and live in a large city were compared to the responses 86 patients who live the rural region of Brühl. In addition, ages, frequency of micturition, use of pads, prior and desired treatment were compared. Limitations of this study include its retrospective study design and the absence of sociodemographic data. Furthermore, the use of a pad test could objectify the extent of incontinence.

RESULTS

On average, patients from Cologne used of 6.2 pads and patients from Brühl used 3 pads. Patients from the large city scored 14 out of 21 points on the ICIQ-SF, and women from Brühl scored 11 out of 21 points. This difference was significant. Patients from Cologne had received medicinal treatment or physical therapy significantly more often.

CONCLUSION

The results suggest that urinary incontinence is perceived as a greater impairment by patients residing in (large) cities compared to patients residing in rural areas. An urban-rural gradient in patients with urinary incontinence can be described.

The self-report fecal incontinence and constipation questionnaire in patients with pelvic-floor dysfunction seeking outpatient rehabilitation

BACKGROUND

Fecal incontinence and constipation affect men and women of all ages.

OBJECTIVE

The purpose of this study was to psychometrically analyze the Fecal Incontinence and Constipation Questionnaire (FICQ) in patients seeking outpatient rehabilitation services due to pelvic-floor dysfunction (PFD).

DESIGN

This was a retrospective analysis of cross-sectional data from 644 patients (mean age=52 years, SD=16, range=18-91) being treated for PFD in 64 outpatient rehabilitation clinics in 20 states (United States).

METHODS

We assessed the 20-item FICQ for unidimensionality and local independence, differential item functioning (DIF), item fit, item hierarchical structure, and test precision using an item response theory model.

RESULTS

Factor analyses supported the 2-factor subscales as originally defined; items related to severity of leakage or constipation. Removal of 2 leakage items improved unidimensionality and local independence of the leakage scale. Among the remaining items, 2 items were suggestive of adjustment for DIF by age group and by number of PFD comorbid conditions. Item difficulties were suitable for patients with PFD with no ceiling or floor effect. Mean item difficulty parameters for leakage and constipation subscales ranged from 38.8 to 62.3 and 28.1 to 63.3 (0-100 scale), respectively. Endorsed leakage items representing highest difficulty levels were related to delay defecation and confidence to control bowel leakage. Endorsed constipation items representing highest difficulty levels were related to the need to strain during a bowel movement and the frequency of bowel movements.

LIMITATIONS

A limitation of this study was the lack of medical diagnostic criteria to classify patients.

CONCLUSIONS

After removing 2 items and adjusting for DIF, the results supported sound psychometric properties of the FICQ items and its initial use for patients with PFD in outpatient rehabilitation services.

Psychometric properties and practicability of the self-report urinary incontinence questionnaire in patients with pelvic-floor dysfunction seeking outpatient rehabilitation

BACKGROUND

Pelvic-floor dysfunction (PFD) affects a substantial proportion of individuals, mostly women. In responding to the demands in measuring PFD outcomes in outpatient rehabilitation, the Urinary Incontinence Questionnaire (UIQ) was developed by FOTO in collaboration with an experienced physical therapist who has a specialty in treating patients with PFD.

OBJECTIVE

The purpose of this study was to evaluate psychometric properties and practicability of the 21-item UIQ in patients seeking outpatient physical therapy services due to PFD.

DESIGN

This was a retrospective analysis of cross-sectional data from 1,628 patients (mean age=53 years, SD=16, range=18-91) being treated for their PFD in 91 outpatient physical therapy clinics in 24 states (United States).

METHODS

Using a 2-parameter logistic item response theory (IRT) procedure and the graded response model, the UIQ was assessed for unidimensionality and local independence, differential item functioning (DIF), discriminating ability, item hierarchical structure, and test precision.

RESULTS

Four items were dropped to improve unidimensionality and discriminating ability. Remaining UIQ items met IRT assumptions of unidimensionality and local independence. One item was adjusted for DIF by age group. Item difficulties were suitable for patients with PFD with no ceiling or floor effect. Item difficulty parameters ranged from -2.20 to 0.39 logits. Endorsed items representing highest difficulty levels were related to control urine flow, impact of leaking urine on life, and confidence to control the urine leakage problem. Item discrimination parameters ranged from 0.48 to 1.18. Items with higher discriminating abilities were those related to impact on life of leaking urine, confidence to control the urine leakage problem, and the number of protective garments for urine leakage.

LIMITATIONS

Because this study was a secondary analysis of prospectively collected data, missing data might have influenced our results.

CONCLUSIONS

Preliminary analyses supported sound psychometric properties of the UIQ items and their initial use for patients with PFD in outpatient physical therapy services.

The impact of disease on family members: a critical aspect of medical care

Most existing health-related quality of life research concerns the impact of disease on patients. However, in several medical specialties including dermatology, oncology, and physical and mental disability, studies have been carried out investigating the impact of disease on the lives of families of patients. The aim of this paper is to review the literature which relates to the impact of disease on family members of patients. The OVIDSP Medline was selected as the primary database, Searches were limited to sources published in English. 158 papers were identified for review. The definition of "family" varied across the literature, and a broad definition was accepted in this review. This review shows that a wide variety of aspects of family members' lives can be affected, including emotional, financial, family relationships, education and work, leisure time, and social activities. Many of these themes are linked to one another, with themes including financial impact and social impact being linked to emotional impact. Some positive aspects were also identified from the literature, including family relationships growing stronger. Several instruments exist to measure the impact of illness on the family, and most are disease or specialty- specific. The impact of disease on families of patients is often unrecognised and underestimated. Taking into account the quality of life of families as well as patients can offer the clinician a unique insight into issues such as family relationships and the effect of treatment decisions on the patient's close social group of partner and family.

The prevalence of urinary incontinence in pregnancy among a multi-ethnic population resident in Norway

OBJECTIVES

To investigate prevalence of urinary incontinence (UI) in a multi-ethnic population of pregnant women, and to analyse for possible associations of the known risk factors for UI in such a population.

DESIGN

Population-based cross-sectional study.

SETTING

All pregnant women in three administrative city districts attending the Child Health Clinics.

POPULATION AND SAMPLE

Out of 823 women identified in the [corrected] first trimester, 772 (94%) [corrected] agreed to participate in the study at 28 weeks of gestation. Inclusion criteria were: healthy women at 20 weeks of gestation or less and able to communicate in Norwegian, Arabic, English, Sorani, Somali, Tamil, Turkish, Urdu or Vietnamese.

METHODS

Differences between ethnic groups were tested by simple descriptive statistics. Associations were estimated by logistic regression analysis and presented as crude (cOR) and adjusted (aOR) odds ratios.

MAIN OUTCOME MEASURES

Prevalence of UI as ascertained using the International Consultation on Incontinence Questionnaire-urinary incontinence-short form.

RESULTS

Prevalence rates of UI at 28 weeks of gestation were 26% for women of African origin, 36% for women of Middle Eastern origin, 40% for women of East Asian origin, 43% for women of South Asian origin and 45% for women of European/North American origin. The difference was significant between women of African and European/North American origins (P = 0.011) and between women of African and South Asian origins (P = 0.035). Age (aOR 1.05; 95% CI 1.01-1.09) and parity (aOR 2.34; 95% CI 1.66-3.28) were positively associated with the prevalence of UI in pregnancy. Women of African origin had significantly reduced odds for UI (aOR 0.42; 95% CI 0.20-0.87). East Asian and African women reported the highest perceived impact of UI in pregnancy.

CONCLUSIONS

A high prevalence of UI was found in a multi-ethnic pregnant population.

Stress urinary incontinence and quality of life: a reliability study of a condition-specific instrument in paper and web-based versions

AIMS

Quality of life is an important outcome measure in studies of urinary incontinence. Electronic collection of data has several advantages. We examined the reliability of the Swedish version of the highly recommended condition-specific quality of life questionnaire International Consultation on Incontinence Modular Questionnaire-Lower Urinary Tract Symptoms Quality of Life (ICIQ-LUTSqol), in paper and web-based formats in women with stress urinary incontinence.

METHODS

Women aged 18-70 years, with stress urinary incontinence at least once weekly, were recruited via the project's website and answered the ICIQ-LUTSqol questionnaire. Respondents completed either the paper version twice (n = 78), or paper and web-based versions once each (n = 54). The ICIQ validation protocol was followed.

RESULTS

The mean interval between answers was 18.1 (SD = 3.1) days in the paper versus paper setting and 15.0 (SD = 7.8) days in the paper versus web-based setting. Internal consistency was excellent, with Cronbach's alpha coefficients of 0.87 for the paper version and 0.86 for the web-based version. There was a high degree of agreement of overall scores with intraclass correlations in the paper versus paper and paper versus web-based settings: 0.95 (P < 0.001) and 0.92 (P < 0.001), respectively. The mean of each individual item's weighted kappa value was 0.61 in both settings.

CONCLUSIONS

The questionnaire is reliable in women with stress urinary incontinence, and it can be used in either a paper or a web-based version.

Content validation of the patient-reported outcomes measurement information system (PROMIS) framework in women with urinary incontinence

AIMS

To assess whether the existing National Institutes of Health (NIH) Patient Reported Outcomes Measurement Information System (PROMIS) conceptual framework and item banks sufficiently capture the concerns of women with urinary incontinence (UI).

METHODS

Thirty-five women with UI were recruited between February-April 2009 for 4 structured focus groups to develop and assess the content validity of a conceptual framework for the impact of UI. This framework included domains from the NIH PROMIS framework and item banks including broad domains of physical and social function and mental health. All sessions were transcribed, coded, and qualitatively and quantitatively analyzed using analytic induction and deductive analysis to identify new themes and domains relevant to women with UI.

RESULTS

The focus groups provided information that confirmed the relevance of existing PROMIS domains and identified new outcome domains that are important to this patient population. The groups confirmed the relevance of the physical and social functioning, and mental health domains. Additional themes that emerged included the distinction between ability versus participation and satisfaction, role functioning, external mediators, re-calibration/coping, cognitive function and new possibilities. Participants also felt strongly that not all domains and items apply to all women with UI and an option to tailor questionnaires and skip non-relevant items was important.

CONCLUSIONS

The PROMIS framework domains are relevant to women with UI, but additional patient-important themes are identified that may improve the comprehensiveness of this assessment framework for measuring outcomes important to women with UI. These results will inform future item content development for UI.
