Abstract

Tabular-based clinical risk prediction models are extensively applied in medical decision support systems; however, two major challenges often reduce their reliability: predictions that contradict basic clinical logic and poorly calibrated probability outputs that weaken threshold-based decision making. This study investigates explainable binary risk prediction using the processed Cleveland subset of the UCI Heart Disease dataset as a public clinical benchmark. A lightweight and CPU-efficient pipeline is proposed by employing an XGBoost classifier integrated with monotonic constraints on clinically relevant features, followed by probability calibration through post-hoc methods, including Platt scaling, temperature scaling, and isotonic regression on a separate validation set. Model performance is assessed in terms of discrimination capability using AUROC, AUPRC, F1-score, sensitivity, and specificity, while probability reliability is evaluated using ECE and Brier score metrics. A monotonicity audit is also conducted through counterfactual feature sweeps to measure violation rates. In addition, the model is applied for risk stratification into low-, medium-, and high-risk categories with corresponding event-rate reporting. The findings demonstrate that isotonic regression improves probability reliability without degrading discrimination performance. Furthermore, the monotonicity audit reveals no observed violations for constrained features. Overall, the integration of monotonic constraints and probability calibration produces more decision-ready risk estimates for threshold-based clinical decision support while maintaining transparency through SHAP-based analysis.

Abstract

Healthcare facilities such as hospitals produce significant amounts of waste from operational and supportive activities. Proper treatment of hospital waste is crucial to prevent negative environmental impacts. Hospital waste and sewage refer to the waste and sewage generated during hospital operations and related activities. Wastewater treatment plants (WWTP) are used to treat liquid waste in hospitals. Currently, wastewater treatment monitoring is conducted manually, posing a threat to the authorities. Wastewater samples are required to be sent to the laboratory that prolongs the duration of results for monitoring wastewater treatment. Inspired by the issue of hospital waste treatment, a monitoring tool for hospital waste treatment is designed employing Arduino, a water pH sensor, and a temperature sensor to diminish the impact of hospital waste. This tool would facilitate the officers in sending samples to the laboratory. The designed tool allows the officers to monitor the hospital wastewater treatment plant's status without the need to visit the plant physically. Water treatment plant monitoring using IoT technology involves the use of a pH sensor, a ds18b20 temperature sensor, and an ultrasonic proximity sensor. This monitoring tool is expected to be used safely to monitor water treatment plants..
