Effectiveness of Current Interventions to Alleviate Parental Distress in the NICU: A Rapid Review

Abstract

Background: The birth of a premature infant and admission to the NICU is often unexpected and traumatic for families, leading to increased distress and can negatively impact parental-infant attachment. Appropriate interventions can help to lessen the negative impact of a NICU admission on families, improving parental mental health, reducing distress, enhancing parent- infant relationships, and improving the long-term physical, cognitive, emotional, and social development of the infant.
 Aims: The purpose of this study is to examine and evaluate research evidence on the effectiveness of current interventions for improving parental distress in the NICU.
 Methods: A rapid review was conducted utilizing a protocol based on the Virginia Commonwealth University guidance. Keyword searches were conducted on CINAHL, MEDLINE, and PsychINFO, and studies were selected according to pre-defined eligibility criteria, published between January 2015 and January 2020. The literature search included primary studies of interventions with parental stress and/or anxiety reduction as outcomes.
 Results: A total of 14 articles were included, evaluating the effectiveness of 13 different interventions, including narrative writing, art therapy, structured nursing interventions, anxiety counselling, spiritual care, organizational change, music therapy, relaxation, and mindfulness techniques. With the Pexception of three, all the studies found significant results in the reduction of stress and/or anxiety levels of the subjects, with mothers having overall higher levels of stress indicated by higher stress scores on standardized measurement tools.
 Conclusion: There is a need for ongoing assessment of parental distress and integration of appropriate interventions within the NICU settings. In this review, both individualized and group interventions including narrative writing, art therapy, music therapy, spiritual care, activity-based group therapy, music therapy, audio-assisted relaxation techniques, mindfulness based neurodevelopmental care, cognitive behavioral based counselling, family nurture intervention and a structured nursing intervention were shown to be effective in reducing parental stress and/or anxiety in the NICU. The small scale of the studies included in this review impact generalizability to a broader audience and emphasizes the need for larger scope, multi-center studies at an international level to build on and broaden our level of knowledge on how to better support families and reduce parental distress in the NICU.

Associations between prematurity, postpartum anxiety, neonatal intensive care unit admission, and stress

“…This study further highlights the need for differential support both during the NICU and across the first postpartum year for mothers of premature infants. Interventions addressing anxiety and stress during NICU admission which focus on structured nursing interventions have been successful at reducing anxiety and stress (64), but interventions must now focus, in the first instance, on addressing concerns specific to the postpartum period, and this support must be differential dependent on categories of gestational age. For example, as the results of this study indicated, mothers of later-premature infants score significantly higher on the practical infant care anxieties subscale, and so interventions may wish to target concerns surrounding this, such as feeding and washing.…”
