SUMMARY
A survey of 514 pregnant women admitted during
1981 to the Antenatal Ward of the Department of
Obstetrics and Gynecology, National Hospital,
Reykjavík, was carried out. The object was to define
the patient population, to estimate the effect of age
and other factors on the risk of acquiring pregnancy
induced disease and to investigate the pregnancy
outcome, comparing it with the outcome for all
women giving birth in Iceland during 1981.
314 patients were admitted once only and 130 on
more than one occasion.
The age distribution was compared with that of
the 4442 women giving birth in Iceland during 1981.
In the hospital group there are relatively fewer
women under the age of 20 but a larger number of
women over the age of 35 than in the national
group. The risk of acquiring pregnancy induced
illness appears to be 4 times greater at the age of 40
than at 20, but does not appear to be affected by
increasing parity or a history of previous miscarria-
ges.
The percentage of primigravidae was the same in
both groups.
77.5 % of the patients were admitted during
weeks 30-40, the risk of becoming ill during preg-
nancy reaching a peak during the last 4 weeks of
pregnancy.
The most common diagnoses were pre-eclampsia
or monosymptomatic hypertension (38 %), iminent
premature delivery (17.8%), dysmaturity (5.2%),
twins (5.2 %) and hæmorrhage (4 %).
The diagnoses at discharge were in general
agreement with the diagnoses prior to admission.
There was a definite tendency to over-diagnose
dysmaturity before admission which shows a heal-
thy low threshold of suspicion.
The caesarean sextion rate was 21 % which is
double the national rate (10.5 %).
The mean weight of the babies was 3246 g which
is 314 g less than the national average. 31.8 % of the
babies received a hospital diagnosis other than
»healthy« on discharge, compared with a national
figure of 15 %. The stillborn rate and the perinatal
mortality was 23 %o and 28 %o respectively com-
pared with 5 %o and 7.8 %o for the whole country.
