COMPARATIVE COST ANALYSIS OF PHILIPS NASAL ALAR SpO2 SENSOR VERSUS DISPOSABLE ALTERNATIVES

Abstract
Introduction Traditional disposable SpO2 sensors, particularly finger sensors, are costly and generate significant medical waste. This study evaluates whether the innovative Philips Nasal Alar SpO2 Sensor can reduce both costs and environmental impact. Methods An economic model was developed to compare costs, operational efficiency and medical waste between the Philips Nasal Alar SpO2 Sensor and traditional disposable sensors in a mid-sized US hospital. Results The economic model demonstrated that using the Philips Nasal Alar SpO2 Sensor in a mid-sized (130 beds) hospital could reduce overall SpO2 monitoring costs by 76% ($1.1 million per year), due to its reusability for/on one patient and extended lifespan. The average cost of SpO2 consumables with Philips Nasal Alar SpO2 Sensor remains below $7.14 per patient per day. This is substantially more affordable than other disposable sensor alternatives, costing $30.2 per patient per day. Using Philips Nasal Alar single patient use SpO2 sensors will generate significantly lessmedical waste compared toall other disposable sensors in a mid-sized hospital, with an annual waste reduction from 2,279kg to 459kg.The lightweight design of the Philips Nasal Alar SpO2sensor supports more environmentally conscious healthcare practices. The Philips Nasal Alar SpO2 Sensor may enhance workflow efficiency in clinical settings by reducing consumption of sensors. Its user-friendly design and reliable performance reduce the time and effort required for sensor repositioning, allowing healthcare providers to focus more on patient care. This improvement streamlines hospital operations and optimizes overall healthcare facility functionality. Conclusions The Philips Nasal Alar SpO2 Sensor provides a comprehensive solution to the financial, operational, and environmental challenges of SpO2 monitoring. The economic model highlights clear cost savingsup to 76% (1.1 million US$ per year), while its operational efficiency and promotion of environmentally conscious healthcare practices underscore the sensor’s value in modern medical settings.
