Lesson Learnt from the Estimate of Maternal Death in Thailand Kanjana Tisayaticom Sudarat Tantivivat Phusit Prakongsai International Health Policy Program (IHPP), Thailand The 3rd Global Forum on Gender Statistics 11-13 October 2010 Manila, Philippines ESA/STAT/AC.219/36
Outline • Introduction • MDG achievements and maternal death in Thailand • Different approaches and statistics of maternal death • Vital statistics - Bureau of Policy and Strategy, MOPH • Multiple sources of data - Thailand Development Research Institute (TDRI) • Reproductive age mortality surveys (RAMOS) and verbal autopsy (VA) • Conclusions and policy recommendations
Objectives of the study To describe differences in maternal death in Thailand using different types of data sources and data collection approaches, To explore strengths and weaknesses of three different approaches in estimation of maternal deaths in Thailand Using vital registration by BPS, MOPH Using multiple data by TDRI, RAMOS technique and verbal autopsy (VA).
Bureau of Policy and Strategy (BPS),MOPH • Vital registration • Death registration (coverage 95.2% in 2006: SPC 2005-2006) • Birth registration (coverage 96.7% in 2006: SPC 2005-2006) • Coding cause of death using ICD 10 by BPS staff • Pregnancy, childbirth and the puerperium O00-O99 • O00-O08 Pregnancy with abortive outcome • O10-O16 Oedema, proteinuria and hypertensive disorders in pregnancy, childbirth and the puerperium • O20-O29 Other maternal disorders predominantly related to pregnancy • O30-O48 Maternal care related to the fetus and amniotic cavity and possible delivery problems • O60-O75 Complications of labour and delivery • O80-O84 Delivery • O85-O92 Complications predominantly related to the puerperium • O94-O99 Other obstetric conditions, not elsewhere classified
Rates of Maternal Deaths per 100,000 Live births by Cause Grouping According to ICD source : Health Information Unit, Bureau of Health Policy and Strategy
Using Multiple Data for Calculating the Maternal Mortality Ratio in Thailand by TDRI • Data sources • Vital registration • Birth registration • Death registration • Inpatient data set • Civil Servant beneficiaries scheme • Universal coverage scheme • Methods • Method 1: Mothers Who Died after Giving a Live Birth • Method 2: Women Ending Pregnancy with Stillbirth or Neonatal Death
Method 1: Mothers Who Died after Giving a Live Birth Birth Registration Obtain PID of mother Death Registration Obtain PID Match same PID from the date of birth plus 42 days Match PID with death certificate Obtain the recorded cause of death Maternal death Incidental cause of death 8
Method 2: Women Ending Pregnancy with Stillbirth or Neonatal Death registration Obtain PID of reproductive-aged women Match same PID of those who have in patient records nine month before the date of death In patient record from UC Obtain PID & ICD10 In patient record from CSMBS obtain PID &ICD 10 Match PID with death certificate Obtain the recorded cause of death Maternal death Incidental cause of death 9
Maternal mortality ratio using TDRI approachwere more than 3 times higher than the estimate from BPS of MOPH
The Reproductive Age Mortality Survey(RAMOS) Method Primarily quantitative Qualitative for verbal autopsies Approach Identifies and investigates all deaths of women of reproductive age (15-49 years) using multiple data sources. Phase 1: Death Identification Phase 2: Death Review
The 1st Phase: Death Identification Identify all deaths in the community through one or more sources as listed below: Routine death registrations Medical records in health facilities Interviews with health care providers Census Multiples sources of information
The 2nd Phase: Death Review Investigate deaths of women reproductive age to determine the cause of death and relatedness to pregnancy through various sources as list below: Medical records and coroners’ reports Interview of health care providers Interview of family members (Verbal Autopsy)
RAMOS and other methods Source: Bureau of Health Promotion 2006 Note: BPS = Bureau of Policy and Strategy MOPH = Ministry of Public Health TDRI = Thailand Development Research Institute * The reproductive age mortality studies (RAMOS) technique identifies and investigates all deaths of women of reproductive age (15-49 years) using multiple data sources. This method includes interviewing household members and health care providers.
Conclusions and policy recommendation • High gaps between the estimate of MMR from vital registration and other approaches, • Improve accuracy of estimate MMR in any approaches inevitably need completeness and accuracy of vital registration, • In developing countries, it is unlikely to conduct RAMOS either annually or biennially due to limited resources and time consuming, • Though Thailand has achieved high coverage of birth and death registration, high proportion of ill-defined cause of death (COD) is the major challenge.
