    Pharmacogenetic (PGx) test is a useful tool for guiding physician on an initiation of an optimal warfarin dose. To implement of such strategy, the evidence on the economic value is needed. This study aimed to determine the cost-effectiveness of PGx-guided warfarin dosing compared with usual care (UC).

    Hypertension incurs a significant healthcare burden in Asia-Pacific countries, which have suboptimal rates of blood pressure (BP) treatment and control. A consensus meeting of hypertension experts from the Asia-Pacific region convened in Hanoi, Vietnam, in April 2013. The principal objectives were to discuss the growing problem of hypertension in the Asia-Pacific region, and to develop consensus recommendations to promote standards of care across the region. A particular focus was recommendations for combination therapy, since it is known that most patients with hypertension will require two or more antihypertensive drugs to achieve BP control, and also that combinations of drugs with complementary mechanisms of action achieve BP targets more effectively than monotherapy. The expert panel reviewed guidelines for hypertension management from the USA and Europe, as well as individual Asia-Pacific countries, and devised a treatment matrix/guide, in which they propose the preferred combination therapy regimens for patients with hypertension, both with and without compelling indications. This report summarizes key recommendations from the group, including recommended antihypertensive combinations for specific patient populations. These strategies generally entail initiating therapy with free drug combinations, starting with the lowest available dosage, followed by treatment with single-pill combinations once the BP target has been achieved. A single reference for the whole Asia-Pacific region may contribute to increased consistency of treatment and greater proportions of patients achieving BP control, and hence reducing hypertension-related morbidity and mortality.

    BACKGROUND: Hypertension is one of the world's most common health conditions and is a leading risk factor for mortality. Although blood pressure can be modified, there is a large proportion of patients whose blood pressure remains uncontrolled. The aim of this study, termed Edvantage 360°, was to gain a deeper understanding of hypertension management in Asia from the perspective of patients and doctors, and to propose strategies to improve blood pressure control.
    METHODS: Conducted in Hong Kong, Indonesia, Malaysia, the Philippines, South Korea, Taiwan, and Thailand, Edvantage 360° was a mixed-methods observational study that used both qualitative and quantitative elements: qualitative interviews and focus groups with patients (N = 110), quantitative interviews with patients (N = 709), and qualitative interviews with doctors (N = 85).
    RESULTS: This study found that, although there is good understanding of the causes and consequences of hypertension among Asian patients, there is a lack of urgency to control blood pressure. Doctors and patients have different expectations of each other and a divergent view on what constitutes successful hypertension management. We also identified a fundamental gap between the beliefs of doctors and patients as to who should be most responsible for the patients' hypertension management. In addition, because patients find it difficult to comply with lifestyle modifications (often because of a decreased understanding of the changes required), adherence to medication regimens may be less of a limiting factor than doctors believe.
    CONCLUSIONS: Doctors may provide better care by aligning with their patients on a common understanding of successful hypertension management. Doctors may also find it helpful to provide a more personalized explanation of any needed lifestyle modifications. The willingness of the doctor to adjust their patient interaction style to form a 'doctor-patient team' is important. In addition, we recommend that doctors should not attribute ineffectiveness of the treatment plan to patient non-adherence to medications, but rather adjust the medication regimen as needed.

    Patient Self-testing (PST) could be an option for present anticoagulation therapy monitoring, but current evidence on its cost-effectiveness is limited. This study aims to estimate the cost-effectiveness of PST to other different care approaches for anticoagulation therapy in Thailand, a low-to-middle income country (LMIC). A Markov model was used to compare lifetime costs and quality-adjusted life years (QALYs) accrued to patients receiving warfarin through PST or either anticoagulation clinic (AC) or usual care (UC). The model was populated with relevant information from literature, network meta-analysis, and database analyses. Incremental cost-effectiveness ratios (ICERs) were presented as the year 2015 values. A base-case analysis was performed for patients at age 45-year-old. Sensitivity analyses including one-way and probabilistic sensitivity analyses (PSA) were constructed to determine the robustness of the findings. From societal perspective, PST increased QALY by 0.87 and costs by 112,461 THB compared with UC. Compared with AC, PST increased QALY by 0.161 and costs by 21,019 THB. The ICER with PST was 128,697 (3625 USD) and 130,493 THB (3676 USD) per QALY gained compared with UC and AC, respectively. The probability of PST being cost-effective is 74.1% and 51.9%, compared to UC and AC, respectively, in Thai context. Results were sensitive to the efficacy of PST, age and frequency of hospital visit or self-testing. This analysis suggested that PST is highly cost-effective compared with usual care and less cost-effective against anticoagulation clinic. Patient self-testing strategy appears to be economically valuable to include into healthcare system within the LMIC context.
