Healthcare professionals find the care of parents following an involuntary pregnancy loss stressful and challenging. They also feel unprepared to support bereaved parents. The challenging nature of this support may have a personal impact on health professionals and the care provided to parents. The aim of this meta-ethnography is to synthesise nurses’ and midwives’ experiences of caring for parents following an involuntary pregnancy loss. A meta-ethnography of ten studies from five countries was carried out. GRADE CERQual was assessed to show the degree of confidence in the review findings. An overarching metaphor, caring in darkness, accompanied by five major themes provided interpretive explanations about the experiences of nurses and midwives in caring for involuntary pregnancy losses: (1) Forces that turn off the light, (2) strength to go into darkness, (3) avoiding stumbling, (4) groping in darkness, and (5) wounded after dealing with darkness. Nursing staff dealt with organizational difficulties, which encouraged task-focused care and avoidance of encounters and emotional connection with parents. However, nurses and midwives might go beyond in their care when they had competencies, support, and a strong value base, despite the personal cost involved.
