Validity of the Danish Prostate Symptom Score questionnaire in stroke

Clinical tools for evaluating the severity of overactive bladder: A systematic review of psychometric properties

OBJECTIVES

To systematically evaluate the evidence describing the psychometric properties of clinical measures for assessing overactive bladder symptoms (urinary urgency with or without urge urinary incontinence, urinary frequency and nocturia). To evaluate the quality of this evidence-base using the COnsensus-based Standards for selecting health status Measurement INstruments (COSMIN) checklist and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) tools.

DATA SOURCES

Five electronic databases (CINAHL, EMBASE, MEDLINE, Scopus and Web of Science) were searched from dataset inception to August 2023.

REVIEW METHODS

Study screening, data extraction and quality appraisal were performed by two independent authors. Inclusion criteria were studies testing one or more psychometric properties of clinical tools for the assessment of overactive bladder symptoms among adults aged 18 years and older for both sexes. The methodological quality and quality of the evidence were evaluated using the COSMIN checklist and GRADE tools, respectively.

RESULTS

The search identified 40 studies totalling 10,634 participants evaluating the psychometric properties of 15 clinical tools. The COSMIN methodological quality was rated good for most measures, and the GRADE quality of evidence ranged from low (13%) to high (33%). The Overactive Bladder Symptom Score, Overactive Bladder Questionnaire and Neurogenic Bladder Symptom Score were of good methodological and high-GRADE evidence qualities.

CONCLUSION

Overactive Bladder Symptom Score, the Overactive Bladder Questionnaire and the Neurogenic Bladder Symptoms Score are promising psychometrically sound measures. The Overactive Bladder Symptom Score has been applied to the most culturally diverse populations supported by studies of good methodological and high-GRADE evidence quality.

Evaluating methods of detecting and determining the type of urinary incontinence in adults after stroke: A systematic review

INTRODUCTION

Urinary incontinence (UI) affects over half of people with stroke. It is unclear which methods are accurate in assessing presence and type of UI to inform clinical management. Diagnosis of UI based on inaccurate methods may lead to unnecessary interventions. The aims of this systematic review were to identify, for adults with stroke, clinically accurate methods to determine the presence of UI and type of UI.

METHOD

We searched seven electronic databases and additional conference proceedings. To be included, studies had to be primary research comparing two or more methods, or use a reference test.

RESULTS

We identified 3846 studies with eight eligible for inclusion. We identified 11 assessment methods within the eight studies. Only five studies had sufficient comparator data for synthesis. Due to heterogeneity of data, results on the following methods were narratively synthesized: Core Lower Urinary Tract Symptom Score (CLSS), clinical history and physical examination, Barthel Activities of Daily Living Index, International Consultation Incontinence Questionnaire Short Form (ICiQ-SF) and urodynamic studies (UDS). Most studies were small and of low to medium quality. All reported differences in sensitivity, and none compared the same assessment methods.

CONCLUSION

Current evidence is insufficient to support recommendations on the most accurate UI assessment for adults with stroke. Further research is needed.

Nocturia and Nocturnal Polyuria in Neurological Patients: From Epidemiology to Treatment. A Systematic Review of the Literature

CONTEXT

Nocturia is among the most common and bothersome lower urinary tract symptoms (LUTS), but there is no clear consensus on how to identify and manage this symptom in the neurological population.

OBJECTIVE

To systematically review the literature about nocturia in neurological patients.

EVIDENCE ACQUISITION

Studies were identified by electronic search of Cochrane and Medline databases. The studies were included if their participants had acquired neurological pathology among multiple sclerosis (MS), Parkinson's disease (PD), stroke, spinal cord injury (SCI), and reported data on the epidemiology, aetiology, diagnosis, or treatment of nocturia. An independent extraction of the articles was performed by two authors using predetermined datasets, including quality-of-study indicators.

EVIDENCE SYNTHESIS

A total of 132 studies were included; 46 evaluated the epidemiology of nocturia, 28 the possible aetiologies, 10 the diagnostic tools, and 60 the treatments. Nocturia prevalence ranged from 15% to 96% depending on the pathology and definition used. It was one of the most frequently reported LUTS in PD and stroke patients. Several validated questionnaires were found to screen for nocturia in this population. Causalities were numerous: LUT, renal, sleep, cardiovascular dysfunctions, etc. Treatments targeted these mechanisms, with an overall risk of bias assessed as high or serious. The highest level of evidence was seen in MS patients: pelvic floor muscle training, cannabinoids, and desmopressin were effective, but not melatonin. In stroke patients, transcutaneous sacral and transcutaneous tibial nerve stimulation (TTNS) improved nocturia; in PD patients, TTNS, solifenacin, and rotigotine did not.

CONCLUSIONS

Nocturia is highly prevalent in patients with neurological disorders. Causalities and treatments are not different from the general population, but are poorly studied in neurological patients.

PATIENT SUMMARY

In this report, we looked at the published studies about nocturia-the fact of waking to void during the hours of sleep-in patients with neurological diseases. We found that nocturia is very frequent in this population, that the causes are the same as in the general population but may be combined, and that treatments are also the same but have an overall weak level of evidence. We conclude that more research is needed on this topic.

The course of post-stroke bladder problems and their relation with functional and mental status and quality of life: A six-month, prospective, multicenter study

Objectives

The aim of this study was to evaluate the frequency and course of post-stroke lower urinary tract dysfunction (LUTD) from early term up to a period of six months and to investigate the relation of LUTD with functional and mental status and quality of life (QoL) in stroke patients.

Patients and methods

This prospective study included a total of 70 stroke patients (44 males, 26 females; mean age 62.7±7.0 years; range, 46 to 79 years) from five different centers across Turkey between June 2015 and January 2017. The patients were questioned using the Danish Prostatic Symptom Score (DAN-PSS) to evaluate LUTD and evaluated using the Modified Barthel Index (MBI), Incontinence QoL Questionnaire (I-QOL), and Mini-Mental State Examination (MMSE) at one, three, and six months.

Results

At least one symptom of LUTD was observed in 64 (91.4%), 58 (82.9%), and 56 (80%) of the patients according to the DAN-PSS at one, three, and six months, respectively. A statistically significant improvement was found in the DAN-PSS, MBI, MMSE, I-QOL total scores, avoidance and psychosocial subgroup scores at six months compared to the first month scores (p<0.05). There was a significant negative correlation between the DAN-PSS symptom score at one month and the MBI, MMSE, and QoL scores at six months. The DAN-PSS bother and total scores were found to be significantly and negatively correlated only with the subscales of the QoL questionnaire.

Conclusion

Based on our study results, LUTD was very common and the prevalence of LUTD findings decreased constantly during six-month follow-up, showing an association with a poor cognitive and functional status and QoL in stroke patients with LUTD.

Reliability and validity of the Turkish version of the Danish Prostatic Symptom Score to assess lower urinary tract symptoms in stroke patients

BACKGROUND

Lower urinary tract dysfunction (LUTD) is one of the most frequently encountered problems in stroke.OBJECTİVE:To assess the validity and reliability of the Turkish Danish Prostatic Symptom Score (DAN-PSS) in stroke patients with LUTD.

METHODS

A total of 50 patients were included in the study. The reliability was assessed using Cronbach α and intraclass correlation coefficient (ICC) methods, and the validity using the correlations between the subgroup and overall scores of DAN-PSS and the scores of the Barthel Index (BI), International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF), and Short Form 36 (SF-36).

RESULTS

The Cronbach α values were found >0.97 and ICC 0.953-0.990 for all subgroup scores. We found a significant negative correlation between all the sub-scores of DAN-PSS and the BI, and a significant positive correlation between all the sub-scores of DAN-PSS and ICIQ-SF (p < 0.05). The symptom score of DAN-PSS had a significant negative correlation with the physical functioning, physical and emotional role subdomains of the SF-36 survey (p < 0.05).

CONCLUSIONS

We have shown the reliability and validity of the Turkish DAN-PSS, and we think that it will be useful to utilize it in the monitoring of patients with stroke and in clinical studies.

Lower Urinary Tract Symptoms, Erectile Dysfunction, and Quality of Life in Poststroke Men: A Controlled Cross-Sectional Study

The aim of the current study was to compare lower urinary tract symptoms (LUTS), erectile dysfunction (ED), and quality of life (QoL) in poststroke and healthy men. Thirty poststroke men with stroke-related LUTS, and as controls, 96 healthy men participated in this controlled, cross-sectional study. Participants filled in the Danish Prostate Symptom Score (DAN-PSS-1) Questionnaire, the International Index of Erectile Function (IIEF-5), the 36-Item Short Form (SF-36), the Nocturia Quality-of-Life (N-QoL) Questionnaire. In the age group ≤55 years, comparing poststroke men with healthy controls both with LUTS, the results indicated DAN-PSS-1, total score median 13 (4-17) versus 3 (2-6), p = .05; IIEF-5 25 (14-25) versus 24 (23-25), p = .06; SF-12, total score 499 (360-679) versus 695 (644-734), p = .02; and N-QoL 98 (70-100) versus 96 (90-100), p = .65. In the age group >55 years, comparing poststroke men with healthy controls both with LUTS, the results indicated DAN-PSS-1, total score 13 (8-24) versus 5 (2-7), p < .01; IIEF-5 13 (5-20) versus 25 (24-25), p < .01; SF-36, total score 585 (456-718) versus 742 (687-772), p < .01; and N-QoL, total score 81 (66-95) versus 98 (80-100), p < .01. The results demonstrated that in age group above, but not below 55 years, poststroke men with LUTS had significantly higher frequency of severe and bothersome LUTS and ED than the healthy controls with LUTS, while QoL and N-QoL were significantly lower in comparison. It is recommended to identify and assess older poststroke men for LUTS, ED, and QoL.

Assessment of voiding dysfunction in Parkinson's disease: Reliability and validity of the Turkish version of the Danish Prostate Symptom Score

AIMS

To investigate the reliability and validity of the Turkish version of the Danish Prostate Symptom Score (Dan-PSS) questionnaire in patients with Parkinson's disease (PD) and to compare the burden of LUTS (Lower urinary tract symptoms) in men and women.

METHODS

For analysis of test-retest reliability, the Turkish version of the Dan-PSS scale was developed using the back translation method, and it was administered on the day of admission and repeated 1 week after in 60 patients with PD. The OAB-q (Overactive Bladder Questionnaire) and PDQ-39 (Parkinson's Disease Questionnaire-39) were administered to 73 patients for validity analysis.

RESULTS

Both the internal consistency (Cronbach's alpha coefficient: 0.99-1.00) and the test-retest reliability (intraclass correlation coefficient: 0.99-1.00) of the Dan-PSS were found to be high in patients with PD. Although weak to moderate correlations were found between the subscales of the Dan-PSS and PDQ-39 (r: 0.20-0.42; P < 0.05), a strong correlation was found with the OAB-q (r: 0.60-0.79; P < 0.05). Nocturnal urination was the most frequent (93.2%), and bothersome (54.8%) symptom. The majority of the symptom and bother responses were similar in men and women.

CONCLUSIONS

Current study shows that the Turkish version of the Dan-PSS questionnaire is an internally consistent, reliable, and valid scale for patients with PD. Therefore, it can be used to evaluate frequency and severity of LUTS in PD. LUTS are commonly seen in patients with PD in both sexes. It is suggested that all patients with PD should be referred for urological assessment.

PRECiS (Patient Reported Evaluation of Cognitive State): psychometric evaluation of a new patient reported outcome measure of the impact of stroke

OBJECTIVE

Determine the psychometric properties of PRECiS (Patient Reported Evaluation of Cognitive State): A new patient-centred, patient reported outcome measure for perceived impact of cognitive problems, developed through qualitative work, systematic review and service user consultation.

DESIGN

An observational study exploring acceptability, internal consistency, construct validity, inter-rater reliability and test-retest reliability, with opportunistic qualitative data on sensitivity to change.

SETTING

Home visits in the community.

PARTICIPANTS

Stroke survivors with self-reported cognitive difficulties and informal carers.

MEASURES

The 27 item PRECiS was self-completed with support, and proxy completed by informal carers. We collected descriptive cognitive screening test data, and measures of overall stroke impact, mood and activities of daily living to explore construct validity.

RESULTS

Data were collected from 159 (visit 1) and 66 (visit 2) stroke survivors and 86 informal carers. PRECiS showed good acceptability (no missing values or floor/ceiling effects, minimal skewness); high internal consistency (α = 0.94, indicative of potential redundancy); with moderate to strong construct correlations in the directions hypothesised (0.40 to 0.74). An intraclass correlation coefficient of 0.85 indicated good test-retest reliability. Where self-reported change had occurred from visit 1 to 2, PRECiS appeared sensitive. Using carers as proxy respondents is not supported by this analysis (inter-rater ICC = 0.43).

CONCLUSIONS

PRECiS is a patient-centred, practical and reliable measure assessing perceived impact of cognitive problems from the unique perspective of stroke survivors.

Is Pelvic Floor Muscle Training Effective for Men With Poststroke Lower Urinary Tract Symptoms? A Single-Blinded Randomized, Controlled Trial

The aim of the current study was to evaluate the effect of pelvic floor muscle training in men with poststroke lower urinary tract symptoms. Thirty-one poststroke men, median age 68 years, were included in this single-blinded randomized controlled trial. Thirty participants, 15 in each group, completed the study. The intervention consisted of 3 months (12 weekly sessions) of pelvic floor muscle training in groups and home exercises. The effect was evaluated by the DAN-PSS-1 (Danish Prostate Symptom Score) questionnaire, a voiding diary, and digital anal palpation of the pelvic floor muscle. The DAN-PSS-1, symptom score indicated a statistical significant improvement ( p < .01) in the treatment group from pretest to posttest, but not in the control group. The DAN-PSS-1, total score improved statistically significantly in both groups from pretest to posttest (treatment group: p < .01; control group: p = .03). The median voiding frequency per 24 hours decreased from 11 at pretest to 7 (36%; p = .04) at posttest and to 8 (27%; p = .02) at follow-up in treatment group, although not statistical significantly more than the control group. The treatment group but not the control group improved statistically significantly in pelvic floor muscle function ( p < .01) and strength ( p < .01) from pretest to posttest and from pretest to follow-up ( p = .03; p < .01). Compared with the control group the pretest to posttest was significantly better in the treatment group ( p = .03). The results indicate that pelvic floor muscle training has an effect for lower urinary tract symptoms, although statistical significance was only seen for pelvic floor muscle.

Reproductive practices by patterns of marriage among Iranian women: study protocol for an explanatory sequential mixed methods design

Background

Nowadays, nearly half of the world population lives in societies with low fertility or the below-replacement fertility. This potentially grounds the critical situation of reduction in the workforce and causes the aging of population due to an overall increase in life expectancy and standard of living. Hence, population and its transitions including the issue of fertility decline has become a topic of intense debate in the agenda-setting and policy-making processes in both the developed and developing countries. In this view, what can practically be done to respond to the fertility decline that entails effectively addressing the determinants of fertility change? In line with the literature, how people form their marriages or patterns of marriage is amongst influencing factors which potentially affect their reproductive practices as diverse societies recognize different conventions for marriage. This study is to examine women’s reproductive practices by the various patterns of marriage using the explanatory sequential mixed methods design.

Methods/design

This study has an explanatory sequential mixed methods design, the follow-up explanations variant model, with two strands. This design will be implemented in two distinct phases. In the first phase, a cross-sectional quantitative study will be done using a cluster sampling strategy on 850 married women 15–49 years old living in Babol city, Iran. In order to obtain a deeper understanding of the results of the quantitative phase, researchers will implement a qualitative research in the second phase of this study. This design will provide an explanation of the quantitative research results using the qualitative evidence.

Discussion

As patterns of marriage have implications for the status of women, their health and fertility, the result of this study can provide a rich source of information for the required health-related interventions and policies are required to put the demographic changes on the right track at micro and macro level and improve the reproductive practices of women at micro level.

Once nocturia, always nocturia? Natural history of nocturia in older men based on frequency-volume charts: the Krimpen study

PURPOSE

Nocturia is a highly prevalent and bothersome symptom that might (spontaneously) resolve. However, longitudinal data are not available on the incidence and resolution of nocturia assessed with frequency-volume charts. In this study we determined the prevalence, incidence and resolution rates of nocturia assessed by frequency-volume charts, and compared nocturnal voiding frequency over time as assessed by frequency-volume charts and questionnaires.

MATERIALS AND METHODS

A longitudinal, population based study was conducted among 1,688 men 50 to 78 years old with followup rounds at 2.1, 4.2 and 6.5 years. Nocturnal voiding frequency was determined with frequency-volume charts and, for comparison purposes, with a question from the International Prostate Symptom Score. Nocturia was defined as nocturnal voiding frequency 2 or greater. Prevalence, incidence and resolution rates were also determined.

RESULTS

At the 2.1-year followup the incidence rate was 23.9% and the resolution rate was 36.7%. The incidence rate was highest in the oldest group (70 to 78 years) and lowest in the youngest (50 to 54 years), whereas the resolution rate was highest in the group 55 to 59 years old and lowest in the oldest group. Because of the high resolution rate, no reliable incidence rates can be calculated. Despite fluctuation, the prevalence of nocturia increased with age and over time (from 34.4% to 44.7% for the total group, p <0.05). Men who had a frequency-volume chart-nocturnal voiding frequency less than International Prostate Symptom Score-nocturnal voiding frequency (6% of the population) more often had this later on.

CONCLUSIONS

In this population frequency-volume chart assessed nocturia shows considerable fluctuation. Nevertheless, prevalence increases over time and with increasing age. Men who once had frequency-volume chart-nocturnal voiding frequency less than International Prostate Symptom Score-nocturnal voiding frequency are more likely to have this again. Therefore, frequency-volume charts as well as the International Prostate Symptom Score should be used when evaluating nocturia.

Is well-being associated with lower urinary tract symptoms in patients with stroke?

OBJECTIVE

This study aimed to assess self-reported well-being in a clinical sample of stroke patients and to identify possible associations with prevalence, severity and bother of lower urinary tract symptoms (LUTS).

MATERIAL AND METHODS

A cross-sectional, clinical survey was initiated whereby stroke patients were invited to complete The WHO-Five Well-Being Index (WHO-5) and a LUTS instrument, the Danish Prostatic Symptom Score (DAN-PSS-1) questionnaire. Of 519 stroke patients invited, 482 subjects were eligible and 407 (84%) respondents answered the questionnaires.

RESULTS

Poor well-being (sum score <13) was reported by 22% of all stroke patients, for women 29% and for men 14%. Depression (sum score <8) was reported by 10%, for women 11% and for men 8%. Poor well-being was significantly (p < 0.01) associated with severity and bother of LUTS. Likewise, poor well-being was significantly (p < 0.001) associated with the prevalence of four different symptom groups of LUTS.

CONCLUSIONS

The results indicate that poor well-being is present in stroke patients with LUTS, especially in women. Likewise, the data showed significant association between poor well-being and LUTS. Screening for well-being and LUTS in stroke patients is strongly recommended.
