Mortality in Central Java: results from the Indonesian mortality registration system strengthening project

Abstract

BackgroundMortality statistics from death registration systems are essential for health policy and development. Indonesia has recently mandated compulsory death registration across the entire country in December 2006. This article describes the methods and results from activities to ascertain causes of registered deaths in two pilot registration areas in Central Java during 2006-2007. The methods involved several steps, starting with adaptation of international standards for reporting causes of registered deaths for implementation in two sites, Surakarta (urban) and Pekalongan (rural). Causes for hospital deaths were certified by attending physicians. Verbal autopsies were used for home deaths. Underlying causes were coded using ICD-10. Completeness of registration was assessed in a sample of villages and urban wards by triangulating data from the health sector, the civil registration system, and an independent household survey. Finally, summary mortality indicators and cause of death rankings were developed for each site.FindingsA total of 10,038 deaths were registered in the two sites during 2006-2007; yielding annual crude death rates of 5.9 to 6.8 per 1000. Data completeness was higher in rural areas (72.5%) as compared to urban areas (52%). Adjusted life expectancies at birth were higher for both males and females in the urban population as compared to the rural population. Stroke, ischaemic heart disease and chronic respiratory disease are prominent causes in both populations. Other important causes are diabetes and cancer in urban areas; and tuberculosis and diarrhoeal diseases in rural areas.ConclusionsNon-communicable diseases cause a significant proportion of premature mortality in Central Java. Implementing cause of death reporting in conjunction with death registration appears feasible in Indonesia. Better collaboration between health and registration sectors is required to improve data quality. These are the first local mortality measures for health policy and monitoring in Indonesia. Strong demand for data from different stakeholders can stimulate further strengthening of mortality registration systems.

How is Indonesia coping with its epidemic of chronic noncommunicable diseases? A systematic review with meta-analysis

“…At the structural level, we recognized three issues: health insurance services for NCD patients [88], the need for a better collaboration between health and registration sectors [61], and the need to address the double burden of NCDs and infectious diseases such as tuberculosis and diabetes [25], which might be aggravated by smoking [39]. …”

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

“…Stroke was the leading cause in both males and females, as observed in other Asian countries, notably China, Indonesia and Thailand. [19][20][21][22] In males, transport accidents, infectious diseases (particularly HIV infection and tuberculosis), and tobacco-and alcoholrelated conditions (especially lung cancer, chronic obstructive pulmonary disease and liver diseases) were among the leading causes. In women, diseases of the circulatory system accounted for four of the five leading causes of death.…”

District‐level impacts of health system decentralization in Indonesia: A systematic review

“…However, the death registration obtained from the death registration department, survey results, and the Indonesian mortality registration system strengthening project (IMRSSP) demonstrated high variability in the number of death records. 46 Limited death records and unorganized death registration data indicate that the quality of data management of health information system at the district level is problematic. 46 A significant proportion of tuberculosis cases were unreported in eight major cities in Indonesia, namely Jakarta, Bandung, Semarang, Surabaya, Medan, Palembang, Banjarmasin, and Jayapura, where most of the population of Indonesia lives.…”

More than 80% of tuberculosis cases treated by private GP in those cities were not reported to the National Tuberculosis Prevention (NTP) office.…”
