Transforming patient management: a study on secure, cost-effective, automated remote monitoring of urine bags.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The increasing demand for efficient patient monitoring systems in healthcare and the growing need for remote monitoring, particularly post-pandemic, emphasise the importance of tracking critical parameters such as urine output, blood oxygen saturation, breath rate, and blood pressure. Urine output, a key indicator of kidney function and medical treatment response, is traditionally assessed manually, posing a significant burden on hospital staff and caregivers. Addressing this, our system facilitates continuous, accurate monitoring of urine output, enhancing patient care and healthcare efficiency. We developed a smartphone application leveraging capacitive sensors and a Wi-Fi-enabled control unit, enabling remote monitoring of urine bag volumes. The system alerts when bags are empty for extended periods or full, this is validated through experiments with volumes ranging from 100 to 1000 mL.The corresponding variations in sensor output voltage confirmed the accuracy of the system. To secure patient data, we incorporated AES-256 encryption with dynamic key generation using patient-specific IDs and OTP-based access control, ensuring data privacy and compliance with healthcare regulations. Our approach offers several advantages: ease of attachment to standard urine bags, non-invasiveness, reusability of bags, and remote monitoring through the mobile application. This innovation automates urine output monitoring, secures patient data, reduces the workload of intensive care nurses, and enhances patient care through precise and continuous monitoring. Unlike existing devices that rely on customised containers or short-range Bluetooth transmission, our system is compatible with standard urine bags, employs cost-effective capacitive copper-tape sensors, and integrates AES-256 encryption with dynamic key generation and OTP-based access control for robust data security. These unique features make the system functionally novel, technically secure, and highly practical for deployment in both hospital and home settings.
