Shared-care models are highly effective and cost-effective for managing chronic hepatitis B in China: reinterpreting the primary care and specialty divide

Background

We evaluate the impact and cost-effectiveness of shared primary-specialty chronic hepatitis B (CHB) care models in China.

Methods

We constructed a decision-tree Markov model to simulate hepatitis B virus (HBV) disease progression in a cohort of 100,000 CHB individuals aged ≥18 years over their lifetime (aged 80). We evaluated the population impacts and cost-effectiveness in three scenarios: (1) status quo; (2) shared-care model with HBV testing and routine CHB follow-ups in primary care and antiviral treatment initiation in specialty care; and (3) shared-care model with HBV testing, treatment initiation and routine CHB follow-up in primary care and treatment for predetermined conditions in specialty care. We evaluated from a healthcare provider's perspective with 3% discounting rate and a willingness-to-pay (WTP) threshold of 1-time China's GDP.

Findings

Compared with status quo, scenario 2 would result in an incremental cost of US$5.79-132.43m but a net gain of 328-16,993 quality-adjusted life years (QALYs) and prevention of 39-1935 HBV-related deaths over cohort's lifetime. Scenario 2 was not cost-effective with a WTP of 1-time GDP per capita, but became cost-effective when treatment initiation rate increased to 70%. In contrast, compared with status quo, secnario 3 would save US$144.59-192.93m in investment and achieve a net gain of 23,814-30,476 QALYs and prevention of 3074-3802 HBV-related deaths. Improving HBV antiviral treatment initiation among eligible CHB individuals substantially improved the cost-effectiveness of the shared-care models.

Interpretation

Shared-care models with HBV testing, follow up and referring of predetermined conditions to specialty care at an appropriate time, especially antiviral treatment initiation in primary care, are highly effective and cost-effective in China.

Traditional practices in post-partum care among Indonesian and Filipino mothers: a comparative study

This study was conducted to assess the traditional practices in post-partum care among Indonesian and Filipino mothers to propose a program to improve maternal and child health. The study utilized a descriptive research design for Indonesian mother respondents (n=110) and Filipino mother-respondents (n=119) conveniently selected. Traditional practices on post-partum care focused on hygienic care, behavioral precautions, breastfeeding, baby care; dietary modifications; and physical activities. Descriptive statistics (frequency and percentage), weighted mean, and independent t-test were used to describe and analyze quantitative information. Four dimensions, including hygienic care (p-value 0.038); breastfeeding and baby care (p-value 0.000); dietary modifications (p-value 0.000); and physical activities (p-value 0.000), showed a statistically significant difference in the assessment of mother respondents on their traditional practices in post-partum care. Meanwhile, the dimension on behavioral precautions (p-value 0.250) yielded statistically no significant difference on the assessment of mother respondents on their traditional practices in post-partum care.

Medication Adherence In Patients With Arterial Hypertension: The Relationship With Healthcare Systems' Organizational Factors

PURPOSE

Arterial hypertension is one of the most common diseases in the world, presenting a great impact on global mortality. Despite having good medication, the best control depends on patient's adherence. Our aim is to characterize the relationship of adherence to medication in hypertensive patients with consultation length and other organizational factors of healthcare systems.

PATIENTS AND METHODS

We performed a comprehensive review of literature using the MeSH terms "hypertension" and "medication adherence". 61 articles were selected for inclusion and adherence parameters were extracted, allowing us to estimate the mean adherence for each country. The adherence was then correlated with organizational aspects of healthcare systems: consultation length, number of health providers (doctors, nurses and pharmacists), number of hospital beds, health expenditure and general government expenditure.

RESULTS

Adherence to medication ranged between 11.8% in Indonesia and 85.0% in Australia. There is much heterogeneity in methodology, but the Morisky Medication Adherence Scale was the preferred method, used in 63.6% of the cases. We found no relation with consultation length, but a significant one with the greater number of health professionals available. Some differences were observed when considering European countries or Morisky Medication Adherence Scale alone.

CONCLUSION

The better the drugs, the better the control of blood pressure, if patients take them. Rather than investing in the prescription of more drugs, it is important to address non-adherence and reduce it to promote better blood pressure control. Organizational factors are relevant constraints and depend on administrative and political decisions. Although they are not always considered, they greatly impact the adherence to medication.

Interventions to improve medication adherence among Chinese patients with hypertension: a systematic review and meta-analysis of randomized controlled trails

OBJECTIVE

A systematic review and meta-analysis of randomized controlled trials (RCTs) were performed to understand the effectiveness of medication adherence (MA) interventions among Chinese patients with hypertension.

METHODS

A literature search was conducted with three English databases (PubMed, Web of Science and Embase) and three Chinese databases (China National Knowledge Infrastructure, Wanfang and VIP Database for Chinese Technical Periodicals) for the period from 1970 to October 2017. Only both RCTs with a minimum of 10 participants in each intervention group and Chinese patients with hypertension as participants were included. A random-effects model was applied to calculate pooled effect sizes with 95% CI. Subgroup analysis was conducted to identify potential sources of heterogeneity from duration of intervention, type of intervener, methods of intervention and sites of intervention. Funnel plots and Egger's test were used to evaluate for publication bias.

KEY FINDINGS

A total of 48 studies met criteria for the meta-analysis, including 14 568 participants, testing 57 independent comparisons. Overall, the effect size revealed that interventions significantly improved MA (pooled relative risk = 1.59, 95% CI: 1.43 to 1.78; pooled Cohen's d = 1.42, 95% CI: 0.976 to 1.876). Interventions were found to significantly reduce blood pressure (BP) (systolic BP: Cohen's d = -0.85, 95% CI: -1.11 to -0.60 and diastolic BP: Cohen's d = -0.73, 95% CI: -1.00 to -0.46). Longer duration of intervention gave better effectiveness. Physician as interventionist, regular follow-up visits and interventions conducted at a hospital were associated with better effectiveness.

CONCLUSION

Adherence interventions improve MA and reduce uncontrolled BP among Chinese patients with hypertension. In the future, investigators should adopt a skill set to address the problem of poor MA.
