Intervention fidelity and its determinants of focused antenatal care package implementation, in south Wollo zone, Northeast Ethiopia.

Background: Focused antenatal care is directed at sustaining maternal health and improving fetal wellbeing to ensure birth of a healthy neonate. Failure to implement focused antenatal care can result in inability to reduce maternal and perinatal morbidity and mortality in low income countries. Due to evidence-practice gaps, however, thousands of maternal, fetal and neonatal lives are still lost every day, mostly from preventable causes. This study aimed to assess focused antenatal care package's intervention fidelity and its determinant factors in South Wollo Zone, Northeast Ethiopia.

Methods: A cross-sectional study design was employed and a total of 898 women who gave birth in the last 6 months prior to data collection were included. Also 16 health extension workers, working in ten selected health posts, were included. Interviews and self-administered questionnaires were used to collect data from mothers and health extension workers. Ten [10] health posts were audited to assess availability and functionality of drugs and supplies to provide focused antenatal care. Mothers were asked whether or not the required level of care was provided. Health extension workers were provided with self-administered questionnaires to assess socio-demographic characteristics, reception of training, facilitation strategies for the implementation of focused antenatal care and ability to classify danger signs. Multilevel linear regression analysis was performed to identify individual and organizational level's factors influencing focused antenatal care package intervention fidelity.

Results: Overall weighted average focused antenatal care package intervention fidelity (implemented as intended/planned) was 49.8% (95% CI: 47.7-51.8), which means the average number of focused antenatal care package interventions women received is 49.8%. Health extension workers implemented 55.1% and skilled providers (nurses, midwives, health officers or medical doctors) 44.9% of focused antenatal care package interventions. Overall antenatal care coverage, irrespective of frequency (at least one visit), was 752/898 women (83.7%; 95% CI: 81.3-86.1); 263/752 women (35.0%; 95% CI: 31.6-38.4) received at least four antenatal visits and only 46/752 women (6.1%; 95% CI: 4.4-7.8) received all recommended components of focused antenatal care. Previous pregnancy-related problems, paternal education and implementation of facilitation strategies were found to be significant factors enhancing focused antenatal care package intervention fidelity.

Conclusion: Focused antenatal care package intervention fidelity in the study area was low; this may imply that the current level of maternal, perinatal and neonatal mortality might be partly due to the low level of focused antenatal care intervention fidelity. Improving implementation of facilitation strategies is highly required to contribute to the reduction of those mortalities.
