Prevalence and characteristics of incident falls related to nocturnal toileting in hospitalized patients.

Objectives: Although nocturia is a risk factor for incident falls in the community, studies are required to gain an understanding of incident falls related to nocturnal toileting in hospitals. The aim of this study is to describe the prevalence and characteristics of incident falls in adult hospitalized patients related to nocturnal toileting.Methods: A retrospective review of the electronic incident reporting and learning system and medical records of inpatients that had an incident fall.Results: The prevalence of toileting-related incident falls was 53% (73/137) and 28% of all incident falls were related to nocturnal toileting.Intravenous fluid infusion was associated with falls related to toileting, whereby median perfusion volume during night-time was 375 ml [IQR: 225-578 ml].Conclusions: The prevalence of nocturnal toileting-related incident falls in hospitals is high. Nocturia could be a leading cause of these incident falls. Intravenous fluid infusion might be part of the aetiology of (iatrogenic) nocturia.

Toileting-related falls at night in hospitalised patients: The role of nocturia.

OBJECTIVE: The purpose of this study was to describe the prevalence and characteristics of toileting-related falls in hospitalised older people. METHODS: Retrospective analysis of falls related to night-time toileting in patients 60 years or over in a tertiary hospital during a one-year period. RESULTS: Overall 34% of falls were related to toileting with at least 44% of these falls occurring during the night. Toilet-related falls peaked between 11 pm and 1 am, a period that coincides with maximum supine-induced diuresis. Almost half of night falls occurred at the bedside. In 80% of night toileting-related falls, patients were mobilising without the recommended level of assistance. Half of all patients had no strategies for toileting documented in their care plan. CONCLUSION: Findings support screening for nocturia in older inpatients and implementation of strategies to reduce both the need for toileting at night and risk factors for falling.

Nocturnal voiding frequency does not describe nocturia-related bother.

AIM: Nocturia frequency has been used as a measure of treatment efficacy for nocturia even though fluctuation of the symptom over time has been well described in the literature. Additionally, given the multifactorial causal pathway and clinically relevant comorbidities, frequency alone may be an insufficient marker of treatment direction. The aim of this study was to investigate factors associated with nocturia-related bother to identify additional variables that may capture the impact of nocturia, direct clinical care and have potential to quantify treatment outcome. METHODS: Prospective data from tertiary hospital Urology and Continence cohorts were matched for identical variables to generate a sample of 204 datasets. Descriptive statistics were obtained to describe the two cohorts. Characteristics of patients were evaluated across levels of nocturia frequency and nocturia-related bother using nonparametric methods; statistically significant differences between groups in each cohort were established. RESULTS: Nocturia frequency alone does not comprehensively reflect attributable bother. Five sleep variables (poor quality sleep, short time to first awakening to void, less than 7 hours of total sleep, primary sleep latency, and daytime sleepiness) and daily urinary urgency were significantly associated with high nocturia-related bother. Attributable bother, despite high-frequency nocturia, was minimized by male gender, lack of daily urinary urgency and good sleep quality. Poor health status, urinary urgency and sleep latency were associated with nocturia frequency. CONCLUSIONS: Items of importance to individuals with nocturia have been identified from patient data. These variables have the potential to sit alongside change in nocturia frequency as potential markers of treatment response.

Does successful treatment of overactive bladder improve co-morbidities in patients with nocturia?

OBJECTIVE: To investigate whether treatment of overactive bladder (OAB), one comorbidity of nocturia, could reduce waking to void and improve other co-existing symptoms. METHODS: A prospective cohort study was conducted at Royal Melbourne Hospital. Participants received 12 weeks of standard treatment, including lifestyle interventions and pharmacotherapy. Outcome measures were nocturia episodes, severity of urinary urgency/incontinence, sleep quality, daytime somnolence, anxiety and depression scores, quality of life and change in blood pressure. RESULTS: Twenty participants completed the study. Nocturia frequency improved by one void per night. Overactive Bladder Symptom Score, sleep quality, first uninterrupted sleep time and systolic blood pressures improved. There were no significant changes in daytime somnolence, mood or quality of life. CONCLUSIONS: In this pilot study, nocturia and other co-morbid dysfunctions appeared to improve when the severity of OAB was reduced. Treatment of OAB co-morbid with nocturia reduces urinary symptoms and may improve sleep parameters and positively impact return to health.

TANGO - a screening tool to identify comorbidities on the causal pathway of nocturia.

OBJECTIVES: To develop a robust screening metric for use in identifying non-lower urinary tract comorbidities pertinent to the multidisciplinary assessment of patients with nocturia. METHODS: Variables having a significant risk association with nocturia of greater than once per night were identified. Discriminating items from validated and reliable tools measuring these comorbidities were identified. A self-completed 57-item questionnaire was developed and a medical checklist and pertinent clinical measures added. Pre-determined criteria were applied to retain or remove items in the development of the Short-Form (SF) screening tool. The tool was administered to 252 individuals with nocturia who were attending either a tertiary level Sleep, Continence, Falls or Rehabilitation service for routine care. Data collected were subjected to descriptive analysis; criteria were applied to reduce the number of items. Using pre-determined domains, a nocturia screening metric, entitled TANGO, was generated. The acronym TANGO stands for Targeting the individual's Aetiology of Nocturia to Guide Outcomes. RESULTS: The demographic characteristics of the sample are described, along with item endorsement levels. The statistical and structural framework to justify deleting or retaining of items from the TANGO Long-Form to the SF is presented. The resultant TANGO-SF patient-completed nocturia screening tool is reported. CONCLUSIONS: A novel all-cause diagnostic metric for identifying co-existing morbidities of clinical relevance to nocturia in patients who present across disciplines and medical specialties has been developed. TANGO has the potential to improve practice and smooth inequalities associated with a siloed approach to assessment and subsequent care of patients with nocturia.
