Factors related to missed opportunities for immunization at urban and suburban primary health centers in Medan
Abstract
Background Missed opportunites for immunization is one of theimportant causes of low immunization coverage that should be
prevented.
Objective To investigate missed opportunities for immunization
and related factors at urban and suburban primary health centers
in Medan.
Methods A cross sectional study was conducted between January-
March 2004. Primary health centers in Medan were divided into
urban (20 primary health centers) and suburban (19 primary
health centers) groups. The sample size was 109 children who
visited primary health centers for immunization. Study was done
by a questionnaire taken after infants received immunization (exit
interview).
Results The proportion of missed opportunities in urban and
suburban area was 22.3% (95% CI 16.9%;27.7%) and 29.9% (95%
CI 24.0%;35.2%) (P=0.191), respectively. Factors such as age of
starting immunization, number of children more than 4, and low
parental attitude about immunization (P=0.001) were related to
missed opportunities for immunization.
Conclusions There is no difference between proportion of missed
opportunities at primary health centers in urban and suburban
area. Related factors to missed opportunities for immunization
are age of starting immunization older than 3 months, number of
children more than 4, and low parental attitude about
immunization.
