The Hadoop Distributed File System (HDFS) is widely used for its scalability and ability to run on commodity hardware. However, it offers limited native encryption, leaving data vulnerable to security risks. Although several encryption techniques exist, traditional algorithms still face performance and security limitations with large-scale medical datasets. Therefore, this study introduces a hybrid encryption framework designed to enhance security in IoHT environments that process large-scale medical Big Data. The framework combines Attribute-Based Encryption (ABE) with the Blowfish cipher to secure data generated by heterogeneous medical devices across the IoHT infrastructure. The proposed approach is benchmarked against established hybrid schemes-CP-ABE + HE, HE + BF, and CP-ABE + AES-to provide a comparative assessment of its security strength and computational performance. The performance assessment employed key computational metrics, including system efficiency, encryption latency, and decryption latency. Experimental results demonstrate that the proposed hybrid scheme delivers superior performance compared to existing approaches, attaining a peak efficiency of 98.5%. The method further achieved encryption and decryption times of 6.8 min and 5.7 min, respectively, indicating improved computational handling of large-scale IoHT data.","PeriodicalId":55069,"journal":{"name":"Health Informatics Journal","volume":"32 1","pages":"14604582261417493"},"PeriodicalIF":2.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145999952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: A synthetic dataset of 1,000 anonymized health records, modeled after the publicly available Cell-Phone Brain Tumour dataset (Kaggle), was generated in MATLAB. The dataset emulated attributes typically collected by IoT-enabled or mobile health devices (e.g., usage duration, radiation exposure), although no physical IoT integration was implemented. The cryptographic modules-FHE, ESSE, and ABS-were implemented and simulated in a MATLAB-based cloud environment. System evaluation focused on encryption latency, query throughput, access control accuracy, and overall operational efficiency. Results: The FHE module achieved an average encryption time of 2.5 s and a computation time of 4.8 s per 1 KB record. ESSE sustained 20 encrypted queries per second with an 85% success rate. ABS enforced decentralized access with 97% accuracy and a false positive rate of 0.002%. When integrated, the system reached 94% operational efficiency across simulated healthcare workloads. Conclusion: The proposed FHE-ESSE-ABS framework advances existing healthcare blockchain solutions by enabling encrypted computation, privacy-preserving search, and fine-grained access control. These findings confirm its feasibility for secure cloud-based healthcare data management and establish a foundation for future real-world deployment in health informatics.","PeriodicalId":55069,"journal":{"name":"Health Informatics Journal","volume":"31 4","pages":"14604582251394616"},"PeriodicalIF":2.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145490888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, none has prevailed as a clear solution. This scoping review studies 24 publications from 2014 to 2023. The aim is to streamline the understanding of current EHR interoperability expectations, practices, and problems, highlight learnings from the Levels of Conceptual Interoperability Model (LCIM), and suggest means for expediting EHR interoperability. Four interoperability levels are visible in EHR compared to seven in the LCIM: technical/foundational, syntactic/structural, semantic, and process/organization. Semantic interoperability-preserving meaning of exchanged data-is the main focus and the problem to solve. Its many expectations cause implementation difficulty. Standardization of data structures, transfer protocols, terminologies, vocabularies, and ontologies are the most common approach, but there is a lack of consensus on standards. Emerging approaches include fuzzy ontologies, natural language processing, and bidirectional transformation. Standardized data structure is not a prerequisite to useful EHR interoperability. Focusing on the state of health records rather than full system integration can expedite interoperability. Different use cases can benefit from various approaches. Artificial intelligence shows promise for handling semi-structured or unstructured data. Stronger regulations may be necessary to guide ongoing integrations.","PeriodicalId":55069,"journal":{"name":"Health Informatics Journal","volume":"31 4","pages":"14604582251385986"},"PeriodicalIF":2.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145369246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Numerous studies have evaluated the quality and readability of these outputs. This study synthesizes these findings through a cross-sectional meta-synthesis. Methods: We identified studies that evaluated responses using the DISCERN instrument, designed to assess the quality of written material. Additionally, we only included studies that also evaluated readability. We recorded the chatbot used, DISCERN scores, the number of words in each question, the number of questions asked, the number of DISCERN evaluators, the readability of responses, and the year the study was conducted. We also assessed the influence of each publication's journal ranking using the Journal Citation Indicator. Results: We identified 42 studies that conducted 86 tests. Chatbot response readability decreased as response quality increased. Forty-nine tests produced responses ranked \"good\" or better, and only 10 scored below college-level readability. We significantly increased readability by adding the phrase \"write responses at sixth-grade reading level\" to prompts that previously produced post-graduate reading level responses in published studies. Discussion: Variable quality and poor readability of chatbot responses reinforce pessimism about their utility. Nevertheless, appropriate \"prompt engineering\" provides scope to enhance response quality and readability.","PeriodicalId":55069,"journal":{"name":"Health Informatics Journal","volume":"31 4","pages":"14604582251388879"},"PeriodicalIF":2.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145314261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results: Eleven co-creation sessions were held involving 115 participants. Findings highlight five key transitional care processes, beginning with patient assessment and evaluation, continuing through discharge planning and adherence to protocols, and extending to post-discharge support and follow-up care. The results show how technology can enhance each of these steps by improving digital literacy, user-friendliness, interoperability, and the flow of information. Cross-cutting barriers such as limited resources, privacy concerns, and lack of trust in technology were also identified.

Objective: This scoping review investigates how pervasive sensing technologies have been utilized in the implementation of HDTs for healthcare, with a focus on understanding the twinning methods, identifying their advantages and limitations, and uncovering key challenges encountered in real-world applications. Methods: We proposed an analytical framework to examine how pervasive sensing technologies are utilized in the implementation of HDTs for personal health management. Using this framework, we conducted a comprehensive literature search across PubMed, Scopus, IEEE Xplore, Web of Science, and Google Scholar. Results: A total of 39 eligible papers were reviewed. We present an analysis of these studies and provide a discussion on the potential and limitations of HDTs in the context of pervasive healthcare.
