Effect on metabolic bone disease markers in the neonatal intensive care unit with implementation of a practice guideline

Metabolic bone disease of prematurity screening and individualized enteral mineral supplementation in high-risk neonates: a quality improvement initiative

OBJECTIVE

Prompted by an alarmingly low screening rate for metabolic bone disease of prematurity (MBDP), we aimed to increase MBDP screening with serum calcium, phosphorous, and alkaline phosphatase at four to six weeks of life in infants born at <1500 g and <32 gestational weeks from a baseline of 27.37% to 90% within one year.

STUDY DESIGN

We used the Institute for Healthcare Improvement's Model for Improvement as a framework. A key driver diagram informed the interventions which were carried out through four Plan-Do-Study-Act cycles.

RESULTS

There were 129 and 130 neonates in the pre-intervention baseline group and post-intervention MBDP bundle group, respectively. MBDP bundled primary screening rates increased from 27.37% to 95.56% (p < 0.001). Furthermore, 20% of infants had an individualized change in their enteral mineral supplementation after the initiative.

CONCLUSIONS

An interdisciplinary team-based quality improvement approach was effective in altering clinical practice to improve screening and subsequent treatment for MBDP.

Catch it before it breaks!: managing metabolic bone disease of prematurity

PURPOSE OF REVIEW

Metabolic bone disease of prematurity, commonly referred to as osteopenia of prematurity, remains prevalent in the neonatal intensive care unit (NICU) despite recent medical advances. It is estimated that up to 60% of extreme low birth weight and 20% of very low-birth-weight infants have metabolic bone disease of prematurity. Often silent, it typically presents with poor growth, increased ventilator dependency and fractures. Clinical sequalae, such as short stature can extend into young adulthood. There is no universal consensus by neonatal intensive care unit clinicians on the screening, diagnosis, or treatment for metabolic bone disease of prematurity. The disease is often diagnosed late by radiographs or incidentally in this highly fragile population.

RECENT FINDINGS

Suggest screening using DEXA (dual-energy X-ray absorptiometry) scans or ultrasound, in combination with serum markers like alkaline phosphatase, phosphorous levels, parathyroid hormone, and tubular reabsorption of phosphate, might identify at-risk babies earlier. The use of protocol-based screenings may aid in early diagnosis.

SUMMARY

We present a review of the risk factors, recent screening methods, diagnosis and management of this prevalent, clinically relevant diagnosis, as well as propose a protocol for the early screening and management of this silent disease.
