Background Caring is a core function of nurses and it confers upon them ethical obligations as ethical agents. Failure to carry out such ethical obligations raises ethical concerns. This study was not intended to explore ethical concerns, but the reported findings reveal problems which have ethical implications. This paper aims to elucidate the ethical issues inherent in the findings and propose strategies to mitigate them. Research design and methods An exploratory-descriptive qualitative design was used within a larger Action Research Study. (...) Data were collected through focus group discussions with nurse/midwives, and through exit interviews which were conducted with the women who participated in the study on their day of discharge. Six focus group discussions and thirty exit interviews were conducted, and data were analysed through thematic analysis. Participants and research context The study took place at selected maternal and child healthcare settings in Lilongwe, Malawi. The participants were nurse/midwives and women who were admitted in maternal and child healthcare settings and were purposively sampled. Ethical considerations Ethical approval was obtained from the relevant ethics committee and all ethical guidelines were followed in the conduct of the study. Findings The findings are presented under three themes which emerged from the data. The findings reveal effects of staff shortages on patient outcomes, problems experienced in low resource clinical settings and disrespectful nurse/patient communication. Conclusion The findings reveal that institutional factors constrain moral agency and patient safety is severely compromised in some of the clinical settings in Malawi which raises serious ethical concerns.
