Background/Aims Adolescent pregnancies are prevalent in Indonesia. This study aimed to explore perceptions from healthcare workers and pregnant adolescents of maternity services for pregnant adolescents. Methods This qualitative exploratory study involved two policymakers, 10 midwives, five doctors, and 10 pregnant adolescents. Data were collected through structured interviews in public health centre consultation rooms. The data were analysed thematically to explore factors that promoted or hindered use of maternity services for pregnant adolescents. Results The identified barriers included a lack of tailored directives, challenges in engaging adolescents, insufficient numbers of skilled healthcare professionals, adolescents' fears and compromised confidentiality. Opportunities for improvement included enhancing service quality through strategic planning and specialised training for midwives and psychologists. Conclusions The study underscores the need to improve maternity services offered for pregnant adolescents by creating a conducive working environment and sensitising healthcare workers and the community to adolescent mothers' needs. Implications for practice There is a need for guidelines in Indonesia specifically on providing care for pregnant adolescents. Healthcare professionals require specialised training and facilities should be made adolescent friendly.
