Components of continuation • The highest continuation rates: methods not affected by compliance • The highest use-effectiveness: coitus-independent methods • Other method related reasons: the pill, coitus-dependent methods
Compliance rates • Poor compliance • Inconsistent use • Irregular – sporadic use • Not using a backup method • Discontinuing the method but failing to substitute another
Consequences of noncompliance • Unintended pregnancy • Side effects • Diminished noncontraceptive benefits

Components of compliance • Contraceptive efficacy • Contraceptive safety • Side effects • Patient comprehension of use • Personal characteristics • Noncontraceptive benefits • Health care provider preferences
Health Belief Model • Patient’s perceptions of susceptibility to consequences • Severity of consequences • Costs versus benefits • Barriers
How to improve contraceptive use? • Unique needs of each patient • Do you accept the need for using a pill daily? Are you willing to take a pill daily? Are you willing to return for follow–up? Are you willing to report side effects? • Use of contraceptives with high compliance
Development of new contraceptive methods • Monthly injectables • Vaginal ring • Transdermal patches • Biodegradable capsule implants
Conclusions • To empower patients to realise their own responsibility for their reproductive health • To work individually with the patient • To develop and promote the use of new contraceptive methods
