Paper text:
worldwide , nearly 600,000 women between the ages of 15 and 49 die every year as a result of complications arising from pregnancy and childbirth.(12 ) these women die not from any disease but during the normal , life - enhancing process of procreation and most of these deaths are avoidable .
maternal mortality is not only a health disadvantage , rather it is a social disadvantage as it puts economic burden on the family , community , governments , and nations .
india is one of the countries with a high maternal mortality ratio ( mmr ) and the highest ( 136,000 ) estimated number of maternal deaths.(3 ) the main causes of maternal mortality in india are hemorrhage , sepsis , abortion , hypertensive disorders , and obstructed labor.(4 ) mmr for india was 407 by srs 1997 estimates and came down to 301 per 100,000 live births by srs 2003 estimates.(4 ) going by this pace we would achieve the mmr of 195 by the year 2012 and of 160 by 2015 , far from the nrhm goal of 100 per 100,000 live births by 2012 or millennium development goal of 109 per 100,000 live births by 2015.(4 ) orissa being an empowered action group ( eag ) state , has a high mmr of 358 per 100,000 live births.(4 ) maternal deaths occur both inside and outside the health institutions . only estimating mortality rates are not beneficial , to know why and how they die is much more important to prevent such deaths . even for deaths which occur in the hospitals ,
the objectives of the study were to elucidate the magnitude and causes of maternal deaths and to explore the factors and/or circumstances contributing to them .
all the maternal deaths at s. c. b. medical college and hospital , cuttack , odisha , from 1 april 2006 to 31 march 2007 were included in the study .
it was an ongoing process of identifying maternal deaths , tracing out their residences , providing prior intimation , and finally paying a visit to the family .
the who definition of maternal deaths was adopted for the study.(56 ) information about maternal deaths was obtained from death register and bed head tickets ( bhts ) .
addresses were noted and letters were dispatched explaining the nature of the study and purpose of the visit to deceased women 's homes .
semi - structured questionnaires were used for interviewing the relative(s ) and the health care provider(s ) ( hcps ) present with the deceased woman .
hcps of the local community as well as in the tertiary hospital were interviewed to verify some of the points of the relatives and to obtain additional information , e.g. constraints in the hospital .
substantial help was taken from the who - developed questionnaires for verbal autopsy and facility - based studies.(6 ) the ses was assessed and classified according to the social score method adopted by the who international collaborative study on family formation pattern and health.(7 ) the ses assessed four variables  educational status and occupation of the head of the household , per capita monthly income and housing .
the study classifies maternal deaths as direct and indirect according to the who classification.(1 ) direct deaths result from obstetric complications of pregnant state ( pregnancy , labor , and puerperium ) .
indirect deaths are those resulting from previously existing disease or disease developing during pregnancy and aggravated by pregnancy .
delays are classified as types i , ii or iii.(8 ) type i delay  delay in seeking modern medical care ; type ii delay  delay in reaching a health facility , and type iii delay  delay in receiving appropriate care at the health facility . of the 50 deaths that had occurred during this period ,
the total number of deliveries and live births in the hospital during the study period was 6941 and 6881 , respectively .
most of the maternal deaths ( 72.1% ) were in the 2030 year age group .
proportional maternal mortality , i.e. maternal deaths per lakh women delivering in each specific age group was 893 , 636 , 588 , and 631 in < 20 , 2024 , 2529 , and > 30 year age group , respectively .
nearly half of these women ( 46.5% ) were illiterates , while 27.9% had education below secondary level .
93% women were married , while two ( 4.7% ) women were unmarried at the time of death .
being a social taboo , the unmarried women tried illegal abortion methods which resulted in fever , bleeding per - vagina , and septicemia ; finally , they were admitted to this tertiary hospital .
most of these women ( 60.5% ) were from low ses ; none were from high ses .
32.6% cases had died due to hypertensive disorders of pregnancy which included eclampsia ( 18.6% ) and pregnancy - induced hypertension ( 14% ) .
most of the deaths were due to eclampsia in pregnancy ( o15.0 , icd-10 ) followed by severe pre - eclampsia ( o14.1 , icd-10 ) .
hemorrhage was mostly post - partum ( o072.0 and o072.1 , icd-10 ) in nature .
the most common immediate(6 ) causes of death were hemorrhage and shock ( 16.3% each ) .
underlying cause of death of the deceased women regarding antenatal care , 58.1% of the deceased women had received adequate antenatal checkup as per rch guidelines,(9 ) while 23% had no anc / tt immunization .
also , 74.4% of these mothers did not take the required amount of ifa tablets.(10 ) all of these deceased women had no prior planning for institutional delivery .
even 67% of these women were never been told about institutional delivery or delivery by skilled birth attendant ( sba ) .
14% and 11.6% were delivered by a traditional healer and a local dhai , respectively .
the minimum distance from home to the nearest health facility was 0.5 km ; the maximum distance was 30 km .
the average distance traveled to reach nearest health facility was 10.9 km ; the average time taken was 1.2 h. 58.5% mothers had to travel for 1 h or more to reach the nearest health facility .
the mode of transport for most of the women ( 51.1% ) was auto - rickshaw .
the mean distance to the referral hospital ( s. c. b. medical college and hospital ) was 81.9 km , while the median time taken for reaching it was 8 h. a majority of deceased women ( 60% ) reached the referral hospital within 10 h. 46.5% of mothers could utilize the medical ambulance services of the first health facility to reach the referral hospital while others hired cars ( 39.5% ) , private ambulances ( 7% ) , or auto - rickshaws ( 7% ) . delays at different levels contributed to the maternal deaths .
type i and type ii delay each had a role in 58% of maternal deaths , while in 46.5% of cases , type iii delay was one of the contributing factors [ table 2 ] .
in most of the cases of maternal deaths , multiple types of delay were co - existing .
the age distribution pattern of the deceased mothers is similar to the pattern of maternal deaths in india.(4 ) 25.6% of these mothers were in the risk group(10 ) at the time of child birth . in a study by sarin et al.,(11 )
the proportional maternal mortality is least in 2030 years although absolute numbers of maternal deaths are highest .
however , proportional number of deliveries and near misses(6 ) in age - specific groups has not been computed for this study .
a study by sarin et al.(11 ) reported that a majority of the maternal deaths were among women belonging to poor class ( 76.4% ) . a majority ( 55.8% ) of deaths in the present study were in primigravida .
oladapo et al.(13 ) reported that about one third of the women who died were experiencing their first child birth .
age at marriage , literacy , socio - economic status , and parity are some of the determinants of maternal mortality and can act as risk factors if are on the unfavorable side.(1014 ) the most common cause of maternal death was hypertensive disorders of pregnancy ( 30% ) .
govt . of india and the who(1415 ) report hemorrhage as the most common cause .
the pattern of causes in this hospital - based study is quite different from that seen in community .
direct cause contributed to 76.7% of all deaths in the hospital . in most of the hospital - based studies in india,(121618 )
a similar study by oladapo et al.(13 ) reported hypertensive disorders of pregnancy ( 28% ) as the most common cause of maternal death followed by hemorrhage ( 21.3% ) and sepsis ( 20.0% ) . here
the common indirect causes of maternal death were malaria ( 10% ) and anemia ( 8% ) . in different hospital - based studies in orissa and other parts of india,(1923 ) the mortality in pregnant women suffering from falciparum malaria ranged from 4% to 66% . in a study by chhabra et al.,(24 )
proper anc check - up , tt immunization , and ifa tablet consumption all help for a better prognostic outcome of childbirth .
many of the deceased mothers had poor anc ( 41.9% ) , inadequate tt immunization ( 37.3% ) , and ifa tablets consumption ( 74.4% ) .
a majority of the mothers ( 67.4% ) had not received any advice for safe confinement .
advice for safe confinement includes advice to deliver the baby at a health institution or by a sba as a routine .
women who are told about safe confinement can be better prepared both psychologically and financially during delivery . the mean distance
to the referral hospital was 81.9 km while the median time taken for reaching it was 8 h. long distances , poor communication facilities , unavailability of transport service , delay in arranging for transport , money and manpower , shifting to multiple facilities , delay in the health facility(s ) , delay in referral , and poor condition of roads were the reasons for the long time interval .
in the present study , type i and type ii delay , each had a role in 58% of maternal deaths , while in 46.5% of cases type iii delay was one of the contributing factors .
multiple delays were major contributing factors for maternal mortality . in a study by cham et al.,(25 ) in 7 of the 32 cases
the process of seeking medical attention was delayed , 27 of the 32 women were delayed in reaching an appropriate medical facility , while 31 women experienced delay in receiving prompt and adequate obstetric care at the hospital level .
distance to health centre and its accessibility , availability of transport , and prompt referral of critical / unmanageable cases are some important determinants to reducing the burden of maternal mortality besides ability to make quick decisions to seek medical help on the part of the stakeholder(s ) .
an attempt has been made in the present study to throw light upon some of the community factors which had contributed to maternal deaths in this tertiary level health center so that steps can be taken to prevent such type of maternal deaths in future .
the pattern of causes of maternal deaths in the hospital is different from that in the community , so the health institution has to be geared up accordingly .
factors like low socio - economic status , low educational level , and delays at different levels should be closely evaluated .
subsequent studies on maternal mortality like surveys of severe morbidity ( near misses)(6 ) will help in providing further evidence .
people have to be made aware about the role of medical institutions in preventing the maternal deaths so that they can take timely decisions to reach health institutions .
background : maternal mortality is a reflection of the care given to women by its society . it is tragic that deaths occur during the natural process of child birth and most of them are preventable.objectives:the present study was undertaken to find out the causes and contributing factors of maternal deaths.materials and methods : all maternal deaths occurring in a year in the medical college and hospital were traced and interviews were taken from the relatives as well as the health care providers who were present at the time of death of the woman.results:out of the total maternal deaths , 72% belonged to 20 - 30 yrs age group , also 46.5% were illiterate , and majority deaths ( 60.5% ) were from low socio - economics status . 
 direct causes were responsible for 76.7% of maternal deaths . 
 hypertensive disorders of pregnancy were most common ( 32.6% ) cause of direct deaths , while malaria ( 9.3% ) and anemia ( 7% ) were most common indirect causes . 
 most of the women had to use their own resources to travel to health care facilities . 
 delays at different levels , often in combination , contributed to the maternal deaths.conclusions:the study will serve as an eye - opener to the bottlenecks present in the community as well as in the health facility so as to take appropriate measures to prevent maternal deaths .
