DEFINITION :
DEFINITION Study of the incidence, distribution and possible control of diseases and other factors relating to health
Slide 3:
Statistics are used to see what is causing disease prevalance and what can be done about it.
We use statistics e.g. maternal deaths, perinatal deaths etc. These are used to determine if there are factors that are occurring that are avoidable and how to avoid them e.g. guidelines or protocols.
PERINATAL MORTALITY RATE (PMR) :
PERINATAL MORTALITY RATE (PMR) ENND = < 7 days old
LNND=> 7 days -28th day.
FSB = stillbirth with no signs of maceration. Was live before delivery.
PMR= FSB+MSB+ENND x1000
Total number of births
Neonatal mortality rate = ENND + LNND x 1000
Total number births
Slide 5:
Stillbirth rate = MSB + FSB x 1000
Total number deliveries
MATERNAL MORTALITY RATIO :
MATERNAL MORTALITY RATIO Number of maternal deaths x 100 000
Number of women pregnant
Different from Maternal Mortality Rate.
CAESARIAN SECTION RATE :
CAESARIAN SECTION RATE Number of caesarian sections performed x 100
Number of LIVE births
