One problem women have successfully using combined hormonal contraception is the limited supplies they are dispensed. Patients at the Women's Health Care Clinic at the Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center have virtually no barriers to method switching, so it is possible to estimate the impacts that more generous prescribing policies have on short-term continuation rates.
Anonymous chart review of all women who initiated hormonal contraception between Jan. 1 and June 30, 2005.
Only 40.4% of women had documented use for at least 3 months. Women dispensed supplies for 3 or more cycles at the initial visit were more likely to continue use for 3 months (47.8%) than were women dispensed fewer cycles (31.9%) (P < .0001).
More liberal dispensing policies may increase the wastage of combined hormonal contraceptive product, but they significantly increase at least intermediate term use of those methods.
