Patients admitted to the Intensive Care Unit (ICU) frequently experience physiological disturbances that significantly affect their sleep quality. These disturbances are triggered by various factors, including repeated medical procedures, environmental noise, discomfort from medical devices, intensive interactions with healthcare workers, inappropriate lighting that disrupts circadian rhythms, pain, and the underlying disease process. Sleep disturbances in ICU patients may slow down the healing process, elevate blood pressure, trigger metabolic disorders, and increase the risk of serious complications such as stroke. This study aims to examine the relationship between anxiety levels and sleep quality among compos mentis patients in the ICU of Sultan Agung Islamic Hospital, Semarang. The research employed a correlational design with a cross-sectional method. A total of 30 respondents were included based on specific criteria. Anxiety levels were measured using the Hamilton Anxiety Rating Scale (HARS), while sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). Data were analyzed using the Chi-Square test to determine the relationship between the two variables. The findings showed that the distribution of male and female respondents was balanced (15 respondents each). The most common medical diagnosis was post-laparotomy (10 respondents), with the dominant age category being late elderly (10 respondents). Anxiety levels were predominantly in the moderate category (18 respondents), while the majority of respondents demonstrated poor sleep quality (17 respondents). Statistical analysis revealed a p-value of 0.001, indicating a significant relationship between anxiety levels and sleep quality. In conclusion, the study highlights that higher levels of anxiety are associated with poorer sleep quality among compos mentis patients in the ICU. These findings emphasize the importance of nursing interventions aimed at reducing anxiety to improve patient sleep quality and support recovery.

The development of information technology has brought significant changes to the medical device procurement process, particularly within government institutions such as the Health Office. The procurement of appropriate, efficient, and objective medical devices is crucial to supporting optimal medical services, yet the decision-making process is often constrained by limited budgets and the complexity of multiple assessment criteria. This study aims to design and implement a decision support system (DSS) based on the TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method to provide recommendations for medical device procurement at the Binjai Health Office. The DSS evaluates six main criteria: price, quality, durability, ease of maintenance, medical necessity, and safety level, using procurement data from the 2022–2024 period. The TOPSIS method is applied to calculate the relative closeness of each alternative to the ideal solution, enabling decision-makers to rank medical device options objectively and systematically. The findings show that the DSS successfully prioritizes procurement alternatives, helping stakeholders allocate budgets more effectively and transparently. In addition, the system minimizes subjective bias by integrating quantitative analysis with clearly defined criteria. The system is implemented in a web-based environment with MySQL as the database, ensuring accessibility and scalability for future use. Overall, this research demonstrates that integrating TOPSIS into a decision support system can enhance the efficiency, accuracy, and accountability of medical device procurement in public health agencies. The study is expected to contribute to improving budget management and strengthening the quality of health services through better resource allocation.

Wireless Medical Sensor Networks (WMSNs) are a key component of modern Healthcare Internet of Things (IoT) systems, enabling continuous and real-time monitoring of patients’ physiological parameters. These networks support timely medical intervention, improve patient outcomes, and facilitate remote healthcare delivery. However, due to the open and resource-constrained nature of WMSNs, they are highly susceptible to various security threats, particularly during the authentication phase. Existing authentication protocols have been found vulnerable to a range of attacks, including impersonation, session key disclosure, and gateway database compromise, which can lead to severe privacy breaches and potentially life-threatening situations. To address these issues, this paper proposes a secure and lightweight three-factor authentication protocol tailored for WMSNs in healthcare IoT environments. The proposed protocol integrates Elliptic Curve Cryptography (ECC) for strong public key-based security with minimal computational overhead, fuzzy extractors to securely handle biometric information and ensure resistance against biometric template compromise, and session-based randomness to achieve forward secrecy and prevent replay or key-compromise impersonation attacks. Security analysis demonstrates that the proposed protocol successfully mitigates prominent threats such as impersonation attacks, man-in-the-middle attacks, session key leakage, and database compromise. In addition, the protocol ensures mutual authentication between the user, the gateway, and the sensor nodes, while maintaining data confidentiality and integrity. Performance evaluation indicates that the protocol offers significantly reduced computational cost and communication delay compared to existing schemes. Its low energy consumption and minimal storage requirements make it suitable for deployment in resource-constrained medical devices and large-scale IoT healthcare networks. The results highlight the protocol’s scalability, energy efficiency, and robustness, making it a practical and secure solution for safeguarding patient data and ensuring trustworthy communication in WMSNs-based healthcare IoT systems.
