Insights
Developmental supportive care significantly improved growth, neurobehavioral function, and cognitive development in preterm infants. This approach enhances physiological stability and developmental outcomes compared to routine care.
Area of Science:
- Neonatal care
- Developmental pediatrics
- Nursing science
Background:
- Preterm infants face significant challenges in growth and development.
- Optimizing care for preterm infants is crucial for long-term outcomes.
- Developmental supportive care (DSC) is an evolving approach in neonatal nursing.
Purpose of the Study:
- To evaluate the impact of developmental supportive care on preterm infants' growth.
- To assess the effects of DSC on neurobehavioral function.
- To determine the influence of DSC on cognitive development in preterm infants.
Main Methods:
- A retrospective study involving 104 preterm infants.
- Comparison between a routine care group (n=49) and a developmental supportive care group (n=55).
- Outcome measures included growth parameters, neurobehavioral function, and cognitive indices (MDI, PDI) before and after 7 days of care.
Main Results:
- Both groups showed growth improvements, but DSC group had significantly higher body weight, length, and head circumference.
- Neurobehavioral scores and cognitive development (MDI, PDI) improved in both groups.
- The developmental supportive care group demonstrated significantly greater improvements in neurobehavioral and cognitive measures.
Conclusions:
- Developmental supportive care effectively promotes growth, neurobehavioral function, and cognitive development in preterm infants.
- DSC offers systematic and individualized nursing approaches superior to routine care.
- This study provides evidence supporting DSC in clinical neonatal nursing practice.
Objective:
To evaluate the effects of developmental supportive care on growth, neurobehavioral function, and cognitive development in preterm infants.
Methods:
In this retrospective study, a total of 104 preterm infants born in our hospital were enrolled and divided into the routine care group (n = 49) and the developmental supportive care group (n = 55) based on the nursing approach they received during their hospitalization. Both groups received nursing care during hospitalization for 7 days. Routine care included monitoring of vital signs, feeding management, environmental control, skin and oral care, positioning, management of clinical conditions, and parental education. Developmental supportive care was implemented on the basis of routine care and comprised individualized care plans, environmental and sensory regulation, clustered care, tactile stimulation, non-nutritive sucking training, kangaroo care, feeding optimization, pain and stress management, parental involvement, and systematic recording and evaluation of the care effects. Outcome measures included body weight, length, head circumference, and chest circumference before and after the care; neurobehavioral function (passive muscle tone, active muscle tone, primitive reflexes, behavioral state, and general status); and cognitive development assessed by the Mental Development Index (MDI) and Psychomotor Development Index (PDI).
Results:
There were no statistically significant differences between the two groups in baseline characteristics, growth indices, neurobehavioral function, or cognitive development before the care (P > 0.05). After the care, growth parameters increased in both groups, with body weight, length, head circumference, and chest circumference significantly higher in the developmental supportive care group than in the routine care group (P < 0.05). Neurobehavioral scores as well as MDI and PDI scores improved in both groups, with significantly greater improvements observed in the developmental supportive care group (P < 0.05).
Conclusions:
Developmental supportive care can effectively promote growth, neurobehavioral function, and cognitive development in preterm infants. Compared with routine care, this model offers systematic and individualized nursing approaches that enhance physiological stability and developmental outcomes, providing reliable evidence for clinical neonatal nursing practice.
