Abstract:
Background: The tetanus, diphtheria and acellular pertussis
vaccine (Tdap) for pregnant women was recommended by the
Advisory Committee on Immunization Practices (ACIP) in
2012 to reduce pertussis morbidity and mortality in infants.
The objective of the proposed capstone study was to compare
preferred English-speaking with non-English preferred
speaking Hispanic women and their decision to accept or
reject third-trimester Tdap vaccination.
Method: Using the electronic medical record, a retrospective
review was be conducted to evaluate patient decisions about
the Tdap vaccination among 182 to 400 Hispanic women who
received prenatal care between 27 and 36 weeks in a large
southwestern public health care system starting in June 1,
2013 through December 2, 2013.
Results: After exploring any potential relationships of co-
variates to the dependent variable, logistic regression was used
to explore the effect of the ability to communicate in English
on the decision to accept Tdap vaccination during pregnancy.
Of all the predictor variables, only education level and number
of total clinic visits were significant predictors. This indicates
that as the level of education increases, the likelihood of
accepting the Tdap vaccine increases. In addition, the more
total number of clinic visits, the likelihood of accepting the
Tdap vaccine also increases. The independent variable
Language however, was not a significant predictor of accepting
Tdap vaccination (p = .785). However, the model overall, was
statistically significant, χ2 (7) = 40.22, p < .001, but with a
relatively low predictive power, Nagelkerke R2 = .163.
