The Global South political economy of health financing and spending landscape - history and presence.

The Global South nations and their statehoods have presented a driving force of economic and social development through most of the written history of humankind. China and India have been traditionally accounted as the economic powerhouses of the past. In recent decades, we have witnessed reestablishment of the traditional world economic structure as per Agnus Maddison Project data. These profound changes have led to accelerated real GDP growth across many LMICs and emerging countries of the Global South. This evolution had a profound impact on an evolving health financing landscape. This review revealed hidden patterns and explained the driving forces behind the political economy of health spending in these vast world regions. The medical device and pharmaceutical industry play a crucial role in addressing the unmet medical needs of rising middle class citizens across Asia, Latin America, and Africa. Domestic manufacturing has only been partially meeting this ever rising demand for medical services and medicines. The rest was complemented by the participation of multinational pharmaceutical industry, whose focus on investment into East Asia and ASEAN nations remains part of long-term market access strategies. Understanding of the past remains essential for the development of successful health strategies for the present. Political economy has been driving the evolution of health financing landscape since the establishment of early modern health systems in these countries. Fiscal gaps these governments face in diverse ways might be partially overcome with the spreading of cost-effectiveness based decision-making and health technology assessment capacities. The considerable remaining challenges ranging from insufficient reimbursement rates, large out-of-pocket spending, and lengthy lag in the introduction of cutting-edge technologies such as monoclonal antibodies, biosimilars, or targeted oncology agents, might be partially resolved only in the long run.

Mortality measures from sample-based surveillance: evidence of the epidemiological transition in Viet Nam.

OBJECTIVE: To report methods and results from a national sample mortality surveillance programme implemented in Viet Nam in 2009. METHODS: A national sample of 192 communes located in 16 provinces and covering a population of approximately 2.6 million was selected using multi-stage cluster sampling. Deaths for 2009 were identified from several local data sources. Record reconciliation and capture-recapture methods were used to compile data and assess completeness of the records. Life tables were computed using reported and adjusted age-specific death rates. Each death was followed up by verbal autopsy to ascertain the probable cause(s) of death. Underlying causes were certified and coded according to international guidelines. FINDINGS: A total of 9921 deaths were identified in the sample population. Completeness of death records was estimated to be 81%. Adjusted life expectancies at birth were 70.4 and 78.7 years for males and females, respectively. Stroke was the leading cause of death in both sexes. Other prominent causes were road traffic accidents, cancers and HIV infection in males, and cardiovascular conditions, pneumonia and diabetes in females. CONCLUSION: Viet Nam is undergoing the epidemiological transition. Although data are relatively complete, they could be further improved through strengthened local collaboration. Medical certification for deaths in hospitals, and shorter recall periods for verbal autopsy interviews would improve cause of death ascertainment.

Increase in asthma and a high prevalence of bronchitis: results from a population study among adults in urban and rural Vietnam.

BACKGROUND: While a large amount of data about the epidemiology of asthma, COPD, chronic bronchitis and respiratory symptoms are available from developed countries, the information about these diseases in developing countries in south-east Asia are scarce. AIM: Assess the prevalence of respiratory diseases and symptoms and their relation with demographic data including smoking habits among adults in rural and urban Vietnam. METHODS: A random sample of subjects aged 21-70 years were invited; 3008 subjects living in an inner city area of Hanoi and 4000 in a rural area of Bavi in northern Vietnam. An internationally used questionnaire was delivered by field workers to the study subjects. The questionnaire was completed by the subjects, or when necessary, by the field workers after reading the questions for the study participants. RESULTS: The response rate was 92% in Bavi and 70% in Hanoi. Of men in Bavi 67.8% (Hanoi 49.7%; p < 0.001) were smokers, while of women 4.2% were smokers in Hanoi (Bavi 1.2%; p < 0.001). The prevalence of ever asthma was in Hanoi 5.6% (Bavi 3.9%; p = 0.003) with no major gender difference. The most common symptom was longstanding cough (Hanoi 18.1%, Bavi 12.0%; p < 0.001) followed by sputum production, while the prevalence of symptoms common in asthma was considerably lower. Although the large difference in smoking habits, respiratory symptoms tended to be only slightly more common in men than women. Family history of asthma and chronic bronchitis, respectively, were strongly associated with both diseases. CONCLUSIONS: The prevalence of asthma in adults may have increased in both urban and rural Vietnam, as the few previous estimates have found 2% of adults having asthma. Half of men in Hanoi and two-thirds in Bavi were smokers versus a few percent of women in both areas. Bronchitic symptoms were common in both men and women.

The incidence of epilepsy in a rural district of Vietnam: a community-based epidemiologic study.

PURPOSE: Epidemiologic studies of epilepsy from developing countries are scarce. As part of a population-based epidemiologic project in Vietnam, EPIBAVI, we studied the incidence and etiology of epilepsy in people in a representative rural region of the country. METHODS: Two identical field surveys were carried out 3 years apart (January to December 2005, and June to December 2008) in the same population of the Bavi District in Vietnam. On both occasions, close to 50,000 members of approximately 13,000 households were screened using a questionnaire for epilepsy. A clinical examination of all screened positive was performed by a neurologist to verify the epilepsy diagnosis, and all incident cases were offered EEG and a CT scan. RESULTS: In the first survey 2.8% screened positive according to the questionnaire. Of these, 19 had epilepsy onset within 1 year preceding the screening, yielding an incidence rate of 40.2 per 100,000 [95% confidence interval (CI) 22.1-58.3]. In the second survey 1.8% were screened positive, and 21 of these had epilepsy onset within 1 year preceding the screening, giving an incidence rate of 42.9 per 100,000 (95% CI 24.5-61.2). The age-adjusted incidence was 44.8 per 100,000 (95% CI 30.6-59.0). The incidence was higher in those younger than 16 years, among people with lower education, and among people with lower income. CT scan was performed in 29 cases and only two cases were found with some abnormalities. DISCUSSION: The incidence rate of epilepsy in rural Vietnam in our study was lower than in developing countries in Latin America and Africa and similar to rates in Europe and North America.

The prevalence of epilepsy in a rural district of Vietnam: a population-based study from the EPIBAVI project.

SUMMARY: A field survey was carried out to determine the prevalence of active epilepsy in northern Vietnam between January and December 2005, when members of approximately 13,000 households were screened for seizure disorders. A clinical examination of all screened positive was performed by a neurologist to verify the epilepsy diagnosis, and all epilepsy cases were offered an EEG. Out of 47,269 screened, 1,338 (2.8%) had a positive response to the questionnaire. Of these, 206 fulfilled the criteria for active epilepsy, yielding a prevalence of 4.4 per 1,000 (95% CI 3.8-5.0), higher among males (5.1) than females (3.7), among those with lower compared with higher education and among single compared with those married. Only 20.6% were seizure-free the year before the examination. The prevalence of active epilepsy in Vietnam is similar to some other Asian countries but lower than in developing countries from Africa and South America.
