Abstract

OBJECTIVE:

To estimate the proportion of obstetric practice web sites in the United States providing information on antenatal influenza and tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccination.

METHODS:

Using www.healthgrades.com, a national random sample of 1,003 obstetric practice web sites was examined for provision of information on antenatal vaccination and other preventive prenatal health topics. Data were collected for this cross-sectional study between September 25, 2014, and November 12, 2014. χ2 tests and odds ratios were calculated to determine significance and magnitude of associations between provision of antenatal vaccination information and other practice characteristics.

RESULTS:

Of 1,003 web sites examined, 229 (22.8%) posted information pertaining to antenatal vaccinations. Only 105 web sites (10.5%) provided up-to-date information about both antenatal influenza and Tdap vaccination. Compared with the proportion posting on antenatal vaccination, significantly more web sites posted on safe foods (40.8%; P<.001), safe medications (36.9%; P<.001), and safe exercise (38.5%; P<.001) during pregnancy. When compared with web sites not mentioning these other prenatal health topics, web sites mentioning these topics were more likely to also mention antenatal vaccination (safe foods: 45.7% compared with 7.1%; odds ratio [OR] 11.07, 95% confidence interval [CI] 7.65–16.01; safe medications: 45.4% compared with 9.6%; OR 7.8, CI 5.58–10.89; safe exercise: 45.9% compared with 8.4%; OR 9.2, CI 6.5–13.03).

CONCLUSION:

A majority of obstetric care practice web sites do not provide information on antenatal vaccinations. Obstetric practices should consider using their web sites to provide reliable information on antenatal vaccinations as many already do for other prenatal health topics.
