Risk factors associated with growth failure in the follow-up of very low birth weight newborns

Objective This study was aimed to determine factors associated with attendance at the second high-risk infant follow-up (HRIF) visit (V2) by 20 months of corrected age after a successful first visit (V1), and the impact of rural residence on attendance rates in a statewide population of very low birth weight (VLBW; <1,500 g) infants. Study Design Data linked from the California Perinatal Quality of Care Collaborative (CPQCC) Neonatal Intensive Care Unit (NICU) database and CPQCC-California Children's Services (CCS) HRIF database. Multivariable logistic regression evaluated independent associations of sociodemographic, maternal, family, neonatal clinical, and individual HRIF program differences (factors) with successful V2 in VLBW infants born in 2010 to 2012. Results Of 7,295 eligible VLBW infants, 75% (5,475) attended V2. Sociodemographic factors independently associated with nonattendance included maternal race of Black (adjusted odds ratio [aOR] = 0.61; 95% confidence interval [CI]: 0.5–0.75), public insurance (aOR = 0.79; 95% CI: 0.69–0.91), and rural residence (aOR = 0.74; 95% CI: 0.61–0.9). Factors identified at V1that were associated with V2 attendance included attending V1 within the recommended window (aOR = 2.34; 95% CI: 1.99–2.75) and early intervention enrollment (aOR = 1.39; 95% CI: 1.12–1.61). Neonatal factors associated with attendance included birth weight ≤750 g (aOR = 1.83; 95% CI: 1.48–2.5). There were significant program differences with risk-adjusted rates ranging from 43.7 to 99.7%. Conclusion Sociodemographic disparities and HRIF program factors are associated with decreased attendance at V2 among VLBW infants. These findings highlight opportunities for quality and process improvement interventions starting in the NICU and continuing through transition to home and community to assure participation in HRIF.

Purpose. Cryotherapy for retinopathy of prematurity (ROP) is effective in reducing the incidence of blindness in premature infants. However, macular complications associated with successful treatment have not yet been well studied. Methods. Eighteen very low birth weight (<1251 g) infants (32 eyes) who received cryotherapy for ROP were examined serially for regression of disease and for development of macular abnormalities. Patient characteristics and treatment factors were evaluated to identify risk factors associated with the development of macular abnormalities after successful cryotherapy. Results. Eleven of 32 eyes (34.4%) that had undergone cryotherapy developed significant macular abnormalities, including macular coloboma-like change (six eyes), macular hyperpigmentation (two eyes), irregularly mottled macular hyperpigmentation and hypopigmentation (two eyes), and macular hyperpigmentation and hypopigmentation with subretinal proliferation (one eye). Corrected visual acuity in affected eyes ranged from 0.15 to 0.03 (20/133 to 20/666) compared with 1.0 to 0.2 (20/20 to 20/100) in treated eyes without macular abnormality (P = .0002). No difference in gestational age was noted between infants who did or did not develop macular coloboma-like lesions or pigment abnormalities. Eyes with macular abnormality had more posterior disease (P = .037) and received significantly more cryotherapy than did eyes without macular abnormality (P = .0005). Conclusions. In very low birth weight infants receiving cryotherapy for ROP, development of macular coloboma-like lesions and macular pigment abnormalities were related to greater severity of ROP and a greater amount of cryotherapy. Macular abnormalities were associated with markedly worse visual outcomes than were treated eyes without macular abnormality.
