Epidemiological survey of post‐void residual urine volume in older adult patients in an acute‐care hospital: A cross‐sectional observational study

Abstract

AbstractAimTo epidemiologically determine post‐void residual urine volume (PVR) and identify the characteristics of “potential” older adult patients with voiding dysfunction in an acute‐care hospital.MethodsA cross‐sectional study was conducted on 614 older adult patients in an acute‐care hospital between November 2018 and May 2019. Using portable ultrasound devices, nurses measured the patients' PVR three times after admission. Lower urinary tract symptoms were evaluated using the Core Lower Urinary Tract Symptom Score prior to admission.ResultsA total of 107 older adult patients (17.4%) had episodes of abnormal PVR ≥100 mL. An age of over 75 years (adjusted odds ratio [aOR]: 1.899) and feeling of incomplete emptying (aOR: 4.337) were associated with having at least one episode of abnormal PVR, whereas neurological or circulatory diseases (aOR: 3.699) were associated with having two or three episodes.ConclusionsThe results showed a high prevalence of abnormal PVR in older adult patients. Screening for PVR in older adult patients aged over 75 years who experience incomplete emptying or neurological or circulatory diseases may help identify those at risk for voiding dysfunction.
