Insights
Late-preterm infants face higher risks of certain health issues and increased healthcare costs compared to term infants. Costs for late-preterm infants decrease over time but remain elevated.
Area of Science:
- Pediatrics
- Neonatal Health
- Public Health
Background:
- Late-preterm infants (33-36 weeks gestation) represent a significant proportion of births.
- Understanding their long-term health outcomes and associated healthcare costs is crucial for resource allocation and care planning.
- Comparison with full-term infants (≥37 weeks gestation) provides a critical benchmark for assessing risks.
Purpose of the Study:
- To compare the incidence of morbidities in late-preterm infants versus term infants during the first three years of life.
- To evaluate and compare healthcare costs for late-preterm and term infants during the first two years and the third year of life.
Main Methods:
- Utilized administrative health records from a large cohort (N=35733) of infants born between 1997 and 2000 with three years of follow-up.
- Employed Cox's proportional hazards models to compare morbidity diagnoses between late-preterm and term infants.
- Analyzed healthcare costs, including mean total costs and cost ratios, post-initial hospital discharge.
Main Results:
- Common hospitalizations for both groups included acute bronchitis, otitis media, and pneumonia; physician visits frequently involved upper respiratory infections.
- Late-preterm infants showed significantly higher hazard ratios for chronic bronchitis (1.64), hearing loss (1.56), and bacterial diseases (1.28).
- Mean total healthcare costs for late-preterm infants were nearly double those of term infants in the first two years ($2568 vs $1285 CAD), with a cost ratio of 1.99. This ratio decreased to 1.46 in the third year.
Conclusions:
- Late-preterm infants experience a higher risk of specific morbidities compared to their term-born counterparts.
- The economic burden associated with late-preterm infants' healthcare is substantial, although it diminishes from nearly double to 46% higher by the third year of life.
Objective:
To compare late-preterm infants (33-36 weeks) with term infants (≥37 weeks) on incidence of morbidities in the first 3 years of life and healthcare costs during the first 2 years of life and third year of life.
Methods:
Administrative health records of live infants born between January 1, 1997, and December 31, 2000 with 3 years follow-up data (N=35733) were linked. First, diagnoses of morbidities were compared between late-preterm and term infants using Cox's proportional hazards models. Healthcare costs expressed as mean total costs and cost ratios, accrued following initial hospital discharge after birth, were also examined.
Results:
The three most common reasons for hospitalisation in late-preterm and term infants were acute bronchitis, otitis media and pneumonia. The most frequent reasons for physician visits included acute upper respiratory infections, otitis media and bronchiolitis. The highest HR were detected for chronic bronchitis 1.64 (1.13-2.39), hearing loss 1.56 (1.14-2.15) and bacterial diseases 1.28 (1.09-1.49). The mean total cost for late-preterm infants during the first 2 years of life was $2568 CAD compared with $1285 CAD for term infants, cost ratio =1.99 (95% CI 1.90 to 2.09). In the third year of life, the cost ratio reduced to 1.46 (95% CI 1.39 to 1.54).
Conclusions:
Late-preterm infants are at higher risk of specific morbidities compared with term infants. Their mean total costs fall from almost double that of term infants during the first 2 years of life, to just 46% greater in the third year of life.
