Essential components of postnatal care – a systematic literature review and development of signal functions to guide monitoring and evaluation

BACKGROUND: Postnatal Care (PNC) is one of the healthcare-packages in the continuum of care for mothers and children that needs to be in place to reduce global maternal and perinatal mortality and morbidity. We sought to identify the essential components of PNC and develop signal functions to reflect these which can be used for the monitoring and evaluation of availability and quality of PNC. METHODS: Systematic review of the literature using MESH headings for databases (Cinahl, Cochrane, Global Health, Medline, PubMed, and Web of Science). Papers and reports on content of PNC published from 2000–2020 were included. Narrative synthesis of data and development of signal function through 7 consensus-building workshops with 184 stakeholders. RESULTS: Forty-Eight papers and reports are included in the systematic review from which 22 essential components of PNC were extracted and used to develop 14 signal functions. Signal functions are used in obstetrics to denote a list of interventions that address major causes of maternal and perinatal morbidity or mortality. For each signal function we identified the equipment, medication and consumables required for implementation. The prevention and management of infectious diseases (malaria, HIV, tuberculosis) are considered essential components of routine PNC depending on population disease burden or whether the population is considered at risk. Screening and management of pre-eclampsia, maternal anaemia and mental health are recommended universally. Promotion of and support of exclusive breastfeeding and uptake of a modern contraceptive method are also considered essential components of PNC. For the new-born baby, cord care, monitoring of growth and development, screening for congenital disease and commencing vaccinations are considered essential signal functions. Screening for gender-based violence (GBV) including intimate partner- violence (IPV) is recommended when counselling can be provided and/or a referral pathway is in place. Debriefing following birth (complicated or un-complicated) was agreed through consensus-building as an important component of PNC. CONCLUSIONS: Signal functions were developed which can be used for monitoring and evaluation of content and quality of PNC. Country adaptation and validation is recommended and further work is needed to examine if the proposed signal functions can serve as a useful monitoring and evaluation tool.
