Supporting play, exploration, and early development intervention (SPEEDI) for preterm infants: A feasibility randomised controlled trial in an Australian context

Abstract Background An early intervention that enhances early development in infants born preterm, called ‘Supporting Play, Exploration and Early Development Intervention’ (SPEEDI) has been shown to be feasible in Virginia, United States, in a pilot study. Infants receive 10 therapy sessions until 3 months' corrected age (CA) (Phase 1[5 hospital sessions] and Phase 2[5 home-based sessions]) in addition to usual care. Aims To determine the feasibility of SPEEDI for very preterm infants in an Australian context. Study design Prospective pilot feasibility randomised controlled trial. Subjects Infants born Outcome measures Primary outcome was feasibility of SPEEDI, including recruitment rate, participant retention, sessions delivered, and therapy fidelity. Secondary outcome measures were developmental outcomes, including the Bayley Scales of Infant and Toddler Development – 3rd Edition (BSID-III) at 4 months' CA. Results Of 19 eligible infants, 17 consented, SPEEDI n = 8 and usual care n = 9 (mean GA = 26.7 weeks [SD 1.4], male n = 10). All participants completed the study, with 80% of SPEEDI therapy sessions completed (90% Phase 1; 72% Phase 2). On average, therapists and parents used 78% and 77% of SPEEDI strategies in each session respectively. Infants in the SPEEDI group had higher scores on the BSID-III for gross motor, and expressive and receptive language subscales at 4 months' CA. Conclusions SPEEDI is a feasible intervention to deliver, and preliminary results suggest that SPEEDI may lead to improved motor and language outcomes at 4 months' CA, with results supporting future larger clinical trials.
