Insights
The Optimal State Scoring Tool (OSST) shows promise for monitoring clinical improvement in infants with severe bronchopulmonary dysplasia (sBPD). Higher OSST scores correlated with better linear growth in these complex patients.
Area of Science:
- Pediatrics
- Neonatology
- Pulmonology
Background:
- Infants with severe bronchopulmonary dysplasia (sBPD) experience complex medical challenges.
- Assessing clinical improvement in sBPD requires reliable measurement tools.
Purpose of the Study:
- To develop and investigate the preliminary validity of the clinician-rated Optimal State Scoring Tool (OSST).
- To assess the OSST's ability to measure factors relevant to clinical improvement in sBPD.
Main Methods:
- The OSST was developed and pilot-tested on 13 infants with sBPD.
- Longitudinal data on OSST scores, linear growth, and steroid dependency were collected.
- Linear mixed-effect models were used to analyze changes in OSST scores and length.
Main Results:
- OSST scores demonstrated a significant positive correlation with linear growth in sBPD patients.
- Infants dependent on steroids exhibited slower linear growth and a slower increase in OSST scores.
- The OSST showed the largest effect size in differentiating between steroid-dependent and non-steroid-dependent groups.
Conclusions:
- Preliminary data suggest the OSST has construct validity for monitoring clinical outcomes in sBPD.
- The OSST may serve as a valuable tool for tracking the progress of infants with severe bronchopulmonary dysplasia.
Objective:
Infants with severe bronchopulmonary dysplasia (sBPD) have complex medical courses. We developed the clinician-rated Optimal State Scoring Tool (OSST) that measures factors relevant to clinical improvement of sBPD and investigated preliminary validity using linear growth outcome and OSST scores in sBPD patients.
Methods:
Tool development process and pilot findings are provided for 13 patients evaluated longitudinally. OSST scores, length measurements, and steroid dependency values were obtained. Changes in OSST scores and lengths were examined using linear mixed-effect models.
Results:
OSST scores were significantly correlated with linear growth (95% CI 0.36, 0.57). The steroid-dependent group showed significantly slower rate of linear growth (95% CI 0.74, 1.05) and slower rate of increase in OSST scores (95% CI 0.99, 2.13) compared to the non-steroid-dependent group, with the OSST showing the largest effect size.
Conclusion:
Pilot data reflect promising evidence for OSST construct validity in monitoring clinical outcomes in sBPD patients.
