Family-centred care interventions in neonatal intensive care units: a scoping review of randomised controlled trials providing a menu of interventions, outcomes and measurement methods

Background Benefits of different types of family-centred care (FCC) interventions in neonatal intensive care units (NICUs) have been reported. However, a comprehensive review of existing FCC intervention studies was lacking.Objective This review aimed at synthesising the characteristics of FCC interventions, related outcomes and measurement methods in randomised controlled trials (RCTs) in NICU, and providing menus of options to favour implementation and further research.Methods We searched PubMed, EMBASE, Web of Science and the Cochrane Library up to 31 January 2022. Interventions were mapped according to five categories as defined by a previous Cochrane review. We described outcome types, measurement populations, measurement methods and timelines. Subgroup analyses were also performed.Results Out of 6583 studies identified, 146 met eligibility criteria. Overall, 52 (35.6%) RCTs tested more than one category of intervention, with a large variety of combinations, with the most frequent category of intervention being the educational (138 RCTs, 94.5%). We identified a total of 77 different intervention packages, and RCTs comparing the same interventions were lacking. The 146 RCTs reported on 425 different outcomes, classified in 13 major categories with parental mental health (61 RCTs, 41.8% of total RCTs) being the most frequent category in parents, and neurobehavioural/developmental outcomes being the most frequent category in newborns (62 RCTs, 42.5%). For several categories of outcomes almost every RCT used a different measurement method. Educational interventions targeting specifically staff, fathers, siblings and other family members were lacking or poorly described. Only one RCT measured outcomes in health workers, two in siblings and none considered other family members.Conclusions A large variety of interventions, outcomes and measurement methods were used in FCC studies in NICU. The derived menus of options should be helpful for researchers and policy makers to identify interventions most suitable in each setting and to further standardise research methods.
