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 5

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

8

Match same PID from the date of birth plus 42 days

Birth Registration Obtain PID of mother

Match PID with death certificate Obtain the recorded cause of death

Incidental cause of deathMaternal death

Death Registration Obtain PID

Method 2: Women Ending Pregnancy with Stillbirth or Neonatal

9

Match same PID of those who have in

patient records nine month before the date

of death

Death registration Obtain PID of reproductive-aged women

Match PID with death certificate Obtain the recorded cause of death

Incidental cause of deathMaternal death

In patient record from CSMBS obtain

Strengths and WeaknessesApproaches Strengths Weaknesses

BPS, MOPH • Availability of routine data • Coverage of birth and death registration over 95%

• High proportion of ill-defined cause of Death (COD)• Require skillful of coding• Require good collaboration between MOPH and Bureau of Registration Administration (BORA)

TDRI • Higher accuracy in delivery related maternal death • Include medically certified COD (IP data)

• High investment in data warehouse and IT infrastructures• Missing data of non hospitalize patient• Ethical violation : invasion of privacy

Reproductive Age Mortality Surveys (RAMOS)

• Can address the mortality of women of reproductive age• Can identify the underlying cause groups of maternal deaths

• Complex, Costly and time-consuming• Requires complete death report and multiple sources 15

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.
