Insights
Reducing unnecessary lab tests for bronchiolitis is linked to shorter hospital stays and lower costs. Adherence to specific Pediatric Respiratory Illness Measurement System (PRIMES) indicators can improve care quality.
Area of Science:
- Pediatric Medicine
- Healthcare Quality Improvement
- Health Economics
Background:
- Bronchiolitis is a common pediatric respiratory illness.
- Current quality metrics for bronchiolitis care vary.
- The Pediatric Respiratory Illness Measurement System (PRIMES) offers indicators for evaluating care.
Purpose of the Study:
- To assess the association between adherence to individual PRIMES indicators and healthcare outcomes for pediatric bronchiolitis.
- To determine if specific PRIMES indicators correlate with reduced length of stay (LOS) and cost.
Main Methods:
- Prospective enrollment of 699 children with bronchiolitis across 5 children's hospitals (2014-2016).
- Evaluation of 16 PRIMES indicators (9 overuse, 7 underuse) for their association with LOS and cost.
- Mixed-effects linear regression analysis, controlling for patient and hospital factors.
Main Results:
- Three overuse indicators (no blood cultures, no complete blood cell counts, no respiratory syncytial virus testing) were significantly associated with shorter LOS and lower costs.
- No blood cultures showed the largest reduction in LOS (-24.3 hours) and cost (-$731).
- Two underuse indicators (documentation of oral intake and hospital follow-up at discharge) were linked to increased costs.
Conclusions:
- A subset of PRIMES quality indicators for bronchiolitis demonstrates strong associations with improved patient outcomes.
- These indicators can be valuable for future quality improvement initiatives in pediatric bronchiolitis care.
- Focusing on reducing unnecessary laboratory testing may lead to significant cost savings and shorter hospitalizations.
Objectives:
To use adherence to the Pediatric Respiratory Illness Measurement System (PRIMES) indicators to evaluate the strength of associations for individual indicators with length of stay (LOS) and cost for bronchiolitis.
Methods:
We prospectively enrolled children with bronchiolitis at 5 children's hospitals between July 1, 2014, and June 30, 2016. We examined associations between adherence to each individual PRIMES indicator for bronchiolitis and LOS and cost. Sixteen indicators were included, 9 "overuse" indicators for care that should not occur and 7 "underuse" indicators for care that should occur. We performed mixed effects linear regression to examine the association between adherence to each individual indicator and LOS (hours) and cost (dollars). All models controlled for patient demographics, patient complexity, and hospital.
Results:
We enrolled 699 participants. The mean age was 8 months; 56% were male, 38% were white, and 63% had public insurance. Three indicators were significantly associated with shorter LOS and lower cost. All 3 indicators were overuse indicators and related to laboratory testing: no blood cultures (adjusted mean difference in LOS: -24.3 hours; adjusted mean cost difference: -$731, P < .001), no complete blood cell counts (LOS: -17.8 hours; cost: -$399, P < .05), and no respiratory syncytial virus testing (LOS: -16.6 hours; cost: -$272, P < .05). Two underuse indicators were associated with higher cost: documentation of oral intake at discharge ($671, P < .01) and documentation of hospital follow-up ($538, P < .05).
Conclusions:
A subset of PRIMES quality indicators for bronchiolitis are strongly associated with improved outcomes and can serve as important measures for future quality improvement efforts.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
