Since 2018, abortion and/or post-abortion care have been integrated into two WHO health facility assessment tools: the Service Availability and Readiness Assessment and the Harmonised Health Facility Assessment. We discuss lessons learnt through experiences integrating abortion into these standardised tools. Our experiences highlight the feasibility of including abortion in health facility assessments across a range of legal contexts. Factors facilitating the integration of abortion include cross-country collaboration and experience sharing, timely inputs into tool adaptations, clear leadership, close relationships among key stakeholders as in assessment coordination groups, use of locally appropriate terminology to refer to abortion and reference to national policies and guidelines. To facilitate high-quality data collection, we identify considerations around question sequencing in tool design, appropriate terminology and the need to balance the normalisation of abortion with adequate sensitisation and education of data collectors. To facilitate appropriate and consistent analysis, future work must ensure adequate disaggregation of recommended and non-recommended abortion methods, alignment with national guidelines and development of a standardised approach for measuring abortion service readiness. Measurement of abortion service availability and readiness should be a routine practice and a standardised component of health facility assessment tools. Evidence generated by health facility assessments that include abortion monitoring can guide efforts to expand access to timely and effective care and help normalise abortion as a core component of sexual and reproductive healthcare.
