Receipt of prescription contraception by commercially insured women with chronic medical conditions.

OBJECTIVE

To assess differences in receipt of prescription contraception among women with and without chronic medical conditions.

METHODS

This observational study used 3 years of administrative claims records for insured women aged 21-45 years who were enrolled in a commercial insurance company in Michigan between 2004 and 2009. Women were considered to have a chronic medical condition if they had at least two claims for one of the following conditions, in order of prevalence in our study population: hypertension, asthma, hypothyroidism, diabetes, obesity, rheumatoid arthritis, inflammatory bowel disease, or systemic lupus erythematosus. Our primary outcome was receipt of prescription contraception, defined by a pharmacy claim or diagnostic or procedural code. We used multivariable logistic regression to estimate the association of chronic condition status with the odds of receiving prescription contraception within 3 years adjusting for age, community-level socioeconomic status, total outpatient visits, and cervical cancer screening.

RESULTS

Of 11,649 women studied, 16.0% (n=1,862) had at least one of the chronic conditions we considered. Of those with a chronic condition, 33.5% (n=623) received prescription contraception during the 3-year study period compared with 41.1% (n=4,018) of those without a chronic condition (P<.001). After adjusting for covariates, women with a chronic condition remained less likely than women without a chronic condition to have received prescription contraception (adjusted odds ratio 0.85, 95% confidence interval 0.76-0.96, P=.010).

CONCLUSION

Despite a greater risk for adverse outcomes with an unplanned pregnancy, women with these chronic conditions were less likely to receive prescription contraception.
