초록	Objectives: Hyperphosphatemia presents a significant health risk for hemodialysis patients, necessitating meticulous dietary control to manage phosphorus levels and mitigate associated complications. The PhosPointer web application was developed as an alternative to conventional paper-based food records, aiming to enhance user experience, save time, and improve overall quality of life for patients and caregivers. The primary objective was to assess the feasibility of PhosPointer among these patients and to examine its impact on phosphorus levels. Methods: In a quasi-experimental study from January to October 2023, we enrolled regular thrice-weekly hemodialysis patients aged 20 years or older, comparing PhosPointer with traditional 7-day food records over one week. Results: 48 participants (68.8% male, mean age 46.8 years, mean BMI 24.8 kg/m2) demonstrated a significantly higher potential for PhosPointer utilization (62.6%) compared to 7-day food records (2.1%) (p<0.001). Participants found the web application less time-consuming (70.8% versus 22.9%, p<0.001), and satisfaction reached 72.9%. Serum phosphate levels exhibited a noteworthy decrease from 6.4 mg/dL (IQR 5.8-7.7 mg/dL) to 5.4 mg/dL (4.2-6.1 mg/dL) within one week of PhosPointer use (p<0.001). Conclusions: PhosPointer demonstrated clear feasibility and benefits for regular thrice-weekly hemodialysis patients, offering an improved approach to dietary management. This web application proved effective in enhancing user satisfaction and controlling serum phosphate levels, particularly among patients under 50 years old.
