The main objective is to provide reliableestimate of

Birth rate

Death rateInfant mortality rate

Also provides data for other measures of

Sample DesignSample Design

A uni-stage stratified simple random samplewithout replacement.

A simple random sample of enumeration block is

selected without replacement from each of thesize classes of towns/cities in each State/UT

The sample unit in

rural areas -village or a segmented village

Urban area- census enumeration block

Revision of SRS sampling frame10-yearly based on recent results of Census

To make necessary modification in thesampling design

To give wider representation of population

To overcome the difficulties/limitations inthe existing scheme

To meet the additional requirements

Enhancing the scope of SRS

Rationalization of SRS forms

Better netting of events

User friendly

Easy for scanning

Streamlining the system

Enhancing the Scope of DataEnhancing the Scope of Data

Data on:

Morbidity

Family planning practices

AbortionBirth history of all currently married

women in reproductive span

Reasons of migration

School attendance (up to 16 years)

Disability

Introduction of Unique IdentificationCode

One of the significant modification proposedis introduction of unique identification code.This will result in :

easy storage and retrieval of data

aggregation at different levels

Cross-classification of various

determinants with fertility and mortalityindicators

Cohort studies


13/21


Causes of Death in SRS

Data on causes of death are useful for healthplanners, administrators, and medicalprofessionals

To identify the public health importance of different

diseasesTo evaluate trends in causes of mortality over time

in order to assess the impact of national healthprograms

To analyze the socio-economic, demographic andlife style factors that are associated with thedeaths due to various diseases

Training/Refresher Training toRGI Staff on verbal Autopsy

Conducting VA in 10 percentresample units

Assignment of causes ofdeaths

Quality Control

Epidemiological analyses

Re-sampling

Objective- 10% of VAs for eachSRS Supervisor will be checkedby collaborating institutions fortraining feedback

Identification of operationalproblems and possible remedialmeasures:

Physician coding100% double coding,

Reconciliation with anotherphysician

Adjudication of disagreements

Present Scenario & Future PlansPresent Scenario & Future Plans

All the SRS Surveyors have been trained and re-trained in the art of canvassing VA

The VA has been introduced in all the states/uts.as an integral component of SRS

The preliminary results for two Half YearlySurveys (2nd HYS, 2002 & 1st HYS, 2003)were presented in Trivandrum Workshop

The results suggest that VA would result ingenerating cause specific mortality by age,sex and other risk factors on a continuousbasis.
