Patient perception and barriers with fluid hydration: A prospective face-to-face interview and counselling from a university hospital stone clinic

Abstract

Introduction Kidney stone disease (KSD) has a lifetime prevalence of up to 14% in the United Kingdom. Primary and secondary prevention of KSD via dietary intervention is a low-cost public health intervention and remains the best preventative strategy against urolithiasis. Material and methods This prospective study was conducted on kidney stone patients attending a stone clinic at our tertiary endourology centre. Patients were taken through a questionnaire, which was completed in the clinic by a trained specialist endourology nurse. Results A total of 259 patients completed the questionnaire. 141 (54.4%) had an active stone during the clinic visit with the remaining 118 (45.6%) with a history of stone treatment. Regarding barriers to fluid intake, 43 (16.6%) patients did not have a habit of drinking water or felt too bloated, 36 (13.9%) did not like the taste, 17 (6.6%) were not thirsty, 10 (3.9%) of patients were too busy. Of those who answered, 108 (46.8%) patients did not believe there was a link between fluid intake and stone formation. A belief of a link between fluid intake and stone formation significantly predicted fluid intake (p = 0.024) with people who did believe in this drinking less water. Conclusions There are numerous perceived barriers to adequate fluid intake, with almost half of all patients not believing that there is a link between fluid intake and stone formation. This misunderstanding may predict a lower fluid intake. More attention should therefore be focussed on patient education and primary prevention aspects to avoid kidney stone recurrence.
