BackgroundImplanon and copper intrauterine contraceptive device (IUCD) are long-acting reversible contraceptives (LARC) available in public primary health care (PHC) South Africa. These methods are the most effective forms of contraception.AimTo evaluate the knowledge, beliefs and practices on provision of LARC.SettingPrimary health care facilities within the Khayelitsha Eastern Substructure, Cape Town.MethodsA descriptive survey of all permanent nurses who provided contraception. Data were collected from 72/90 (80% response rate) via a validated questionnaire and evaluated using Statistical Package for Social Sciences (SPSS).ResultsKnowledge of eligibility for LARC was tested. The mean knowledge scores for Implanon were 8.56/11 (s.d. 1.42) for the trained and 7.16/11 (s.d. 2.83) for the untrained (p= 0.007). The mean knowledge scores for IUCD were 10.42/12 (s.d. 1.80) for the trained and 8.03/12 (s.d. 3.70) for the untrained (p= 0.019). Participants believed that inaccessibility to training courses (29%), no skilled person available (24%) and staff shortages (35%) were barriers. Less than 50% of women were routinely counselled for LARC. Forty-one percent of nurses were trained and performed IUCD insertion, and 64% were trained and performed Implanon insertion, while 61% and 45% required further training. Confidence was low, with 32% trained and confident in IUCD and 56% trained and confident in Implanon insertion.ConclusionLack of training, poor confidence and deficient counselling skills were barriers to effective LARC provision. The identified system-specific barriers must be addressed to improve uptake.ContributionThe first study to evaluate knowledge, beliefs and practices on LARC in providers in the Western Cape.
