  1. Fulltext A lightweight and robust authentication scheme for the healthcare system using public cloud server
    Abbasi IA, Jan SU, Alqahtani AS, Khan AS, Algarni F
    PLoS One, 2024;19(1):e0294429.
    PMID: 38289970 DOI: 10.1371/journal.pone.0294429
    Cloud computing is vital in various applications, such as healthcare, transportation, governance, and mobile computing. When using a public cloud server, it is mandatory to be secured from all known threats because a minor attacker's disturbance severely threatens the whole system. A public cloud server is posed with numerous threats; an adversary can easily enter the server to access sensitive information, especially for the healthcare industry, which offers services to patients, researchers, labs, and hospitals in a flexible way with minimal operational costs. It is challenging to make it a reliable system and ensure the privacy and security of a cloud-enabled healthcare system. In this regard, numerous security mechanisms have been proposed in past decades. These protocols either suffer from replay attacks, are completed in three to four round trips or have maximum computation, which means the security doesn't balance with performance. Thus, this work uses a fuzzy extractor method to propose a robust security method for a cloud-enabled healthcare system based on Elliptic Curve Cryptography (ECC). The proposed scheme's security analysis has been examined formally with BAN logic, ROM and ProVerif and informally using pragmatic illustration and different attacks' discussions. The proposed security mechanism is analyzed in terms of communication and computation costs. Upon comparing the proposed protocol with prior work, it has been demonstrated that our scheme is 33.91% better in communication costs and 35.39% superior to its competitors in computation costs.

  2. Fulltext Materiovigilance in Perspective: Understanding Its Concept and Practice in the Global Healthcare System
    Sapkota B, Palaian S, Shrestha S, Ibrahim MIM
    Ther Innov Regul Sci, 2023 Jul;57(4):886-898.
    PMID: 37106236 DOI: 10.1007/s43441-023-00514-4
    Materiovigilance (Mv) has the same purpose and approach in ensuring patient safety as pharmacovigilance but deals with medical devices associated with adverse events (MDAEs) and their monitoring. Mv has been instrumental in recalling many defective or malfunctioning devices based on their safety data. All MDAEs, such as critical or non-critical, known, or unknown, those with inadequate or incomplete specifications, and frequent or rare events should be reported and evaluated. Mv helps to improve medical devices' design and efficiency profile and avoid device-related complications and associated failures. It alerts consumers and health professionals regarding counterfeit or substandard devices. Common events reported through Mv are device breakage and malfunction, entry- and exit-site infections, organ perforations or injuries, need for surgery and even death, and life cycle assessment of devices. Health authorities globally have developed reporting frameworks with timeframes for MDAEs, such as MedWatch in the USA, MedSafe in New Zealand, and others. Health professionals and consumers need to be made aware of the significance of Mv in ensuring the safe use of medical devices and getting familiar with the reporting procedures and action plans in case of a device-induced adverse event.

  3. Fulltext E2EE enhanced patient-centric blockchain-based system for EHR management
    Haddad A, Habaebi MH, Elsheikh EAA, Islam MR, Zabidi SA, Suliman FEM
    PLoS One, 2024;19(4):e0301371.
    PMID: 38557695 DOI: 10.1371/journal.pone.0301371
    To secure sensitive medical records in the healthcare clouds, this paper proposes an End-to-End Encryption (E2EE) to enhance a patient-centric blockchain-based system for electronic health record (EHR) management. The suggested system with a focus on the patient enables individuals to oversee their medical records within various involved parties by authorizing or withdrawing permission for access to their records. Utilizing the inter-planetary file system (IPFS) for record storage is chosen due to its decentralized nature and its ability to guarantee the unchangeability of records. Then an E2EE enhancement maintains the medical data integrity using dual level-Hybrid encryption: symmetric Advanced Encryption Standard (AES) and asymmetric Elliptic Curve Cryptography (ECC) cryptographic techniques. The proposed system is implemented using the Ethereum blockchain system for EHR data sharing and integration utilizing a web-based interface for the patient and all users to initiate the EHR sharing transactions over the IPFS cloud. The proposed system performance is evaluated in a working system prototype. For different file sizes between 512 KB to 100 MB, the performance metrics used to evaluate the proposed system were the time consumed for generating key, encryption, and decryption. The results demonstrate the proposed system's superiority over other cutting-edge systems and its practical ability to share secure health data in cloud environments.

  6. The impact of immigration on health systems: a legal analysis from a three-country perspective
    Blum J, Carstens P, Talib N
    Med Law, 2005 Jun;24(2):323-36.
    PMID: 16082868
    The focus of this paper will be on how health care systems in three countries, Malaysia, South Africa and the United States, are responding to the health needs of immigrants with a strong focus on the legal aspects of the respective national responses. The Malaysia portion emphasizes legal immigration and analyses as to how the country's Ministry of Health and the delivery system itself is responding to the demands of immigrant's health. In the context of South Africa, the paper explores implications of the South African Constitution, which establishes a right to access health care, and explores whether such a right can be extended to non-citizens, or can be tempered by economic constraints. In the American discussion the focus is on whether publicly supported health care programs can be accessed to provide coverage for undocumented residents, and highlights recent constraints in using government monies in this area.

  8. The patient's view
    Rachagan SS, Sharon K
    Med J Malaysia, 2003 Mar;58 Suppl A:86-101.
    PMID: 14556356
    The medical practitioner has always had to juggle several roles. First and foremost, the doctor is a healer, a provider of curative services. Second, he is an examiner, an assessor of the patient's health status. Third, he is a researcher, always trying to push the boundaries of medical knowledge. Fourth, he is a rationer of services, he decides how best to apportion the limited resources at his disposal. Traditionally, the patient-doctor relationship has been largely exclusive in nature and the doctor would quite comfortably slip in and out of these roles, his focus centred on his patient's interests. In this era of large corporate health care providers, multi-billion-biotechnology industry, mammoth pharmaceutical companies, medical insurance schemes and international trade instruments, it has become increasingly difficult for the doctor to juggle these four roles. He is constantly subjected to conflicting demands. Patients' interests do not always come first anymore and patients are beginning to realise this. They no longer trust the medical profession unreservedly. There has been steady erosion of the patient-doctor relationship most clearly evidenced by the rising tide of litigation against doctors. There needs to be a reappraisal of these roles that the doctor plays. The conflicts must be recognised and addressed. Patients need to be informed and their interests must be protected if the doctor-patient relationship is to be restored. Medical malpractice suits are on the increase. The tort system as it exists is failing both doctors and patients. The question we must ask is what are patients looking for when they sue doctors? Most of the time they need compensation for the injuries suffered. Sometimes they are looking for accountability, they want the doctor to be punished in some way. Sometimes they merely want to air their grievances and know that they are heard. The current system more often than not takes too long to compensate, the process is a gamble and doctors who are clearly negligent quietly settle and are rarely censured. We need to revamp the existing system to allow for speedy and equitable compensation; true accountability; and articulation and auditing of standards of practice.

  11. Fulltext Health-care data collecting, sharing, and using in Thailand, China mainland, South Korea, Taiwan, Japan, and Malaysia
    Aljunid SM, Srithamrongsawat S, Chen W, Bae SJ, Pwu RF, Ikeda S, et al.
    Value Health, 2012 2 1;15(1 Suppl):S132-8.
    PMID: 22265060 DOI: 10.1016/j.jval.2011.11.004
    This article sought to describe the health-care data situation in six selected economies in the Asia-Pacific region. Authors from Thailand, China mainland, South Korea, Taiwan, Japan, and Malaysia present their analyses in three parts. The first part of the article describes the data-collection process and the sources of data. The second part of the article presents issues around policies of data sharing with the stakeholders. The third and final part of the article focuses on the extent of health-care data use for policy reform in these different economies. Even though these economies differ in their economic structure and population size, they share some similarities on issues related to health-care data. There are two main institutions that collect and manage the health-care data in these economies. In Thailand, China mainland, Taiwan, and Malaysia, the Ministry of Health is responsible through its various agencies for collecting and managing the health-care data. On the other hand, health insurance is the main institution that collects and stores health-care data in South Korea and Japan. In all economies, sharing of and access to data is an issue. The reasons for limited access to some data are privacy protection, fragmented health-care system, poor quality of routinely collected data, unclear policies and procedures to access the data, and control on the freedom on publication. The primary objective of collecting health-care data in these economies is to aid the policymakers and researchers in policy decision making as well as create an awareness on health-care issues for the general public. The usage of data in monitoring the performance of the heath system is still in the process of development. In conclusion, for the region under discussion, health-care data collection is under the responsibility of the Ministry of Health and health insurance agencies. Data are collected from health-care providers mainly from the public sector. Routinely collected data are supplemented by national surveys. Accessibility to the data is a major issue in most of the economies under discussion. Accurate health-care data are required mainly to support policy making and evidence-based decisions.

  12. Fulltext Current state of acute stroke care in Southeast Asian countries
    Ng JC, Churojana A, Pongpech S, Vu LD, Sadikin C, Mahadevan J, et al.
    Interv Neuroradiol, 2019 Jun;25(3):291-296.
    PMID: 30463501 DOI: 10.1177/1591019918811804
    Acute stroke care systems in Southeast Asian countries are at various stages of development, with disparate treatment availability and practice in terms of intravenous thrombolysis and endovascular therapy. With the advent of successful endovascular therapy stroke trials over the past decade, the pressure to revise and advance acute stroke management has greatly intensified. Southeast Asian patients exhibit unique stroke features, such as increased susceptibility to intracranial atherosclerosis and higher prevalence of intracranial haemorrhage, likely secondary to modified vascular risk factors from differing dietary and lifestyle habits. Accordingly, the practice of acute endovascular stroke interventions needs to take into account these considerations. Acute stroke care systems in Southeast Asia also face a unique challenge of huge stroke burden against a background of ageing population, differing political landscape and healthcare systems in these countries. Building on existing published data, further complemented by multi-national interaction and collaboration over the past few years, the current state of acute stroke care systems with existing endovascular therapy services in Southeast Asian countries are consolidated and analysed in this review. The challenges facing acute stroke care strategies in this region are discussed.

  13. Fulltext Consensus statement on the role of health systems in advancing the long-term well-being of people living with HIV
    Lazarus JV, Safreed-Harmon K, Kamarulzaman A, Anderson J, Leite RB, Behrens G, et al.
    Nat Commun, 2021 07 16;12(1):4450.
    PMID: 34272399 DOI: 10.1038/s41467-021-24673-w
    Health systems have improved their abilities to identify, diagnose, treat and, increasingly, achieve viral suppression among people living with HIV (PLHIV). Despite these advances, a higher burden of multimorbidity and poorer health-related quality of life are reported by many PLHIV in comparison to people without HIV. Stigma and discrimination further exacerbate these poor outcomes. A global multidisciplinary group of HIV experts developed a consensus statement identifying key issues that health systems must address in order to move beyond the HIV field's longtime emphasis on viral suppression to instead deliver integrated, person-centered healthcare for PLHIV throughout their lives.

  15. Challenges in the management of breast cancer in low- and middle-income countries
    Yip CH, Taib NA
    Future Oncol, 2012 Dec;8(12):1575-83.
    PMID: 23231519 DOI: 10.2217/fon.12.141
    The incidence of breast cancer is rising in low- and middle-income countries (LMICs) due to 'westernization' of risk factors for developing breast cancer. However, survival remains low because of barriers in early detection and optimal access to treatment, which are the two main determinants of breast cancer outcome. A multidisciplinary approach to treatment gives the best results. An accurate diagnosis is dependent on a reliable pathology service, which will provide an adequate pathology report with prognostic and predictor information to allow optimal oncological treatment. Stratification of clinical practice guidelines based on resource level will ensure that women will have access to treatment even in a low-resource setting. Advocacy and civil society play a role in galvanizing the political will required to meet the challenge of providing opportunities for breast cancer control in LMICs. Collaboration between high-income countries and LMICs could be a strategy in facing these challenges.

  16. Fulltext Healthcare Databases in Thailand and Japan: Potential Sources for Health Technology Assessment Research
    Saokaew S, Sugimoto T, Kamae I, Pratoomsoot C, Chaiyakunapruk N
    PLoS One, 2015;10(11):e0141993.
    PMID: 26560127 DOI: 10.1371/journal.pone.0141993
    Health technology assessment (HTA) has been continuously used for value-based healthcare decisions over the last decade. Healthcare databases represent an important source of information for HTA, which has seen a surge in use in Western countries. Although HTA agencies have been established in Asia-Pacific region, application and understanding of healthcare databases for HTA is rather limited. Thus, we reviewed existing databases to assess their potential for HTA in Thailand where HTA has been used officially and Japan where HTA is going to be officially introduced.

    Han MC
    World Hosp Health Serv, 1997;33(2):8-13.
    PMID: 10174544
    The current status and directions for changes of issues related to quality care in health services in Asian countries--Malaysia, China, Singapore, Japan and Korea are overviewed. In countries with public sector dominated health care systems such as Malaysia. China and Singapore, governmental leadership in quality care is prominent along with legislative backup. Japan and Korea have private sector dominated health care systems and quality care activities are mainly carried out by non-governmental organisations. Hospital accreditation programs are in the developing stages in most countries, although China and Korea started in 1980. Most Asian countries are at the initial stages in quality care activities and focus has been placed on education and training. Asian countries are not exempted from efforts to enhance quality care activities and a new horizon in quality health care is emerging.

    Shah S, Abbas G, Riaz N, Anees Ur Rehman, Hanif M, Rasool MF
    Expert Rev Pharmacoecon Outcomes Res, 2020 Aug;20(4):343-354.
    PMID: 32530725 DOI: 10.1080/14737167.2020.1782196
    BACKGROUND: Communicable diseases such as AIDS/HIV, dengue fever, and malaria have a great burden and subsequent economic loss in the Asian region. The purpose of this article is to review the widespread burden of communicable diseases and related health-care burden for the patient in Asia and the Pacific.

    AREAS COVERED: In Central Asia, the number of new AIDS cases increased by 29%. It is more endemic in the poor population with variations in the cost of illness. Dengue is prevalent in more than 100 countries, including the Asia-Pacific region. In Southeast Asia, the annual economic burden of dengue fever was between $ 610 and $ 1,384 million, with a per capita cost of $ 1.06 to $ 2.41. Globally, 2.9 billion people are at risk of developing malaria, 90% of whom are residents of the Asia and Pacific region. The annual per capita cost of malaria control ranged from $ 0.11 to $ 39.06 and for elimination from $ 0.18 to $ 27.

    EXPERT OPINION: The cost of AIDS, dengue, and malaria varies from country to country due to different health-care systems. The literature review has shown that the cost of dengue disease and malaria is poorly documented.
