Impact of Computerized Growth Monitoring and Referrals on Early Detection of Pediatric Growth Disorders in Primary Care

Project Abstract

This study evaluates the effectiveness of a computerized growth monitoring and referral (CGMR) system integrated into primary care workflows to enhance the early detection of pediatric growth disorders. A quasi-experimental design was employed in which multiple primary care clinics implemented CGMR alongside standard care, with matched clinics continuing usual practices serving as controls. The CGMR system automatically collects longitudinal anthropometric data, plots growth trajectories against standardized growth charts, flags abnormal growth patterns, and generates clinician-ready referral recommendations to pediatric endocrinology or nutrition services. Data were collected over 24 months from children aged 0–18 years presenting for routine visits. Primary outcomes included time to recognition of growth abnormalities, referral rates to specialists, accuracy of initial referral appropriateness, and subsequent diagnostic confirmation of growth disorders. Secondary outcomes encompassed clinician adherence to CGMR alerts, patient follow-up rates, time to treatment initiation, and parental satisfaction. Quantitative analyses utilized interrupted time-series models to assess changes in detection timeliness and referral behavior, controlling for clinic size, demographic variables, and seasonal effects. Qualitative assessments involved semi-structured interviews with pediatricians, family physicians, nurses, and administrators to explore perceived barriers, facilitators, and workflow integration challenges associated with CGMR implementation. The results demonstrate a statistically significant reduction in time from initial abnormal growth signal to specialist referral in intervention clinics, with median times decreasing by an estimated 34% compared to controls (p < 0.01). The proportion of appropriate referrals—defined as referrals leading to a confirmed growth disorder or a clearly documented alternative etiology—improved from 52% to 78% post-implementation (p < 0.001). Diagnostic yield for growth disorders increased modestly but significantly, with earlier stage presentation allowing timely initiation of growth-promoting and disease-specific interventions. Clinician adherence to CGMR alerts exceeded 85% in routine visits, although engagement waned during high-volume periods. Parental satisfaction regarding communication of growth concerns and the perceived clarity of referral pathways improved, with qualitative themes highlighting enhanced trust and shared decision-making. Cost-effectiveness analysis indicated that CGMR adoption was associated with favorable incremental cost per diagnosis and reasonable budget impact when scaled across comparable systems, driven largely by reduced duplicate testing and expedited care trajectories. Sensitivity analyses confirmed robustness of findings across alternative definitions of detection timeliness and referral appropriateness. The study identifies key facilitators, including seamless EHR integration, automated alert customization, and multidisciplinary referral networks, as well as barriers such as alert fatigue and variability in clinic staffing. These findings support broader implementation of CGMR in primary care settings as a viable strategy to improve early detection of pediatric growth disorders, optimize referral pathways, and accelerate initiation of targeted interventions, while underscoring the need for ongoing training, workflow optimization, and continuous monitoring to sustain gains.

Project Overview

What This Project Is About

---

The project explores how using computerized systems to track a child’s growth and trigger referrals can help detect pediatric growth disorders earlier in primary care settings. It looks at how growth data is collected, stored, interpreted, and used to prompt timely medical action, with a focus on practical implementation in clinics and its effects on outcomes for children.
