A Pilot Study to Evaluate PureWick for Nocturia

Study Overview
=================
Brief Summary
-----------------
This is a single-center prospective pilot study of PureWick used as a management for nocturia and reduction of nighttime falls associated with going to the bathroom. Subjects are followed up to 3 months after the intervention. As a pilot study, it is expected that a 3-month follow-up will adequately capture urinary and sleep outcomes data and any adverse events related or unrelated to the study device.

Detailed Description
-----------------
Nocturia is a highly prevalent condition among older adults, significantly affecting the quality of life as well as putting them at an increased risk of falls and fractures. In those 65 and older, accidental falls are identified as the leading cause of injury and death. The chance of falling increases from 30% to 50% with age greater than 85 years. A study identified that in 1508 ambulatory men and women, nighttime urination of 2 times at night is associated with increased risk of falls (OR=1.84, 95% CI 1.05-3.22), with significantly higher risks when it increased to 3 or more times at night (OR=2.15, CI 95% -1.04-4.44). Incontinence management that reduces the need to get out of bed will lead to reduced risk of falls and unintentional injury fatalities. The PureWick Urine Collection System is intended for non-invasive urine output management. It pulls urine through tubing that is connected to a collection canister for proper disposal. It is designed to be used by patients, caregivers, or healthcare professionals in both home environments and professional care facilities. The PureWick System allows individuals to void while still in bed, demonstrating the potential to reduce the risks of falls associated with nighttime voids in men and women with nocturia. We hypothesize that this will also improve sleep quality and overall quality of life.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The proportion of patients at 3 months who have a demonstrated 50% or greater reduction in the number of nocturia episodes/night | The proportion of patients at 3 months who have a demonstrated 50% or greater reduction in the number of nocturia episodes/night will be calculated via binomial proportions and an exact (Clopper-Pearson) 95% confidence interval will be computed to assess the precision of the obtained estimate. | 3 months | 
| Change in average number of nocturnal voids at baseline and at 3 months | The paired t-test or Wilcoxon signed-rank test will be used, as appropriate, to compare the average number of nocturnal voids between baseline and at 3 months. | At baseline and 3 months | 
| Change of scores on the N-QoL at baseline and at 3-months | N-QoL (Nocturia quality of life) score is determined by the n-qol short form. The ICIQ-Nqol is a patient-completed questionnaire evaluating quality of life (QoL) in patients with nocturia for use in research and clinical practice across the world. The ICIQ-Nqol is the N-QoL adapted for use within the ICIQ structure and provides a detailed and robust measure to assess the impact of nocturia on quality of life with particular reference to the effects on patient' lives of Nocturia and can be used as an outcome measure to assess impact of different treatment modalities. 0-52 overall score with greater values indicating increased impact on quality of life Bother scale not incorporated into overall score but indicate impact of symptoms overall for the patient. Similar analyses to paired t-test or Wilcoxon signed-rank test will be performed to compare scores on the N-QoL, an self-reported sleep quality between baseline and at 3-months. | At baseline and 3 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in the incidence of urinary tract infection (UTI) at baseline and 3 months | McNemar's chi-square test will be used to compare the incidence of UTI between baseline and at 3 months. | At baseline and 3 months | 
| Change in the incidence of pressure ulcers/skin breakdown at baseline and 3 months | McNemar's chi-square test will be used to compare pressure ulcers/skin breakdown between baseline and at 3 months. | At baseline and 3 months |
