Effect of an Enhanced Medical Home on Serious Illness and Cost of Care Among High-Risk Children With Chronic Illness A Randomized Clinical Trial

IMPORTANCE Patient-centered medical homes have not been shown to reduce adverse outcomes or costs in adults or children with chronic illness. OBJECTIVE To assess whether an enhanced medical home providing comprehensive care prevents serious illness (death, intensive care unit [ICU] admission, or hospital stay >7 days) and/or reduces costs among children with chronic illness. DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial of high-risk children with chronic illness (≥3 emergency department visits, ≥2 hospitalizations, or ≥1 pediatric ICU admissions during previous year, and >50% estimated risk for hospitalization) treated at a high-risk clinic at the University of Texas, Houston, and randomized to comprehensive care (n = 105) or usual care (n = 96). Enrollment was between March 2011 and February 2013 (when predefined stopping rules for benefit were met) and outcome evaluations continued through August 31, 2013. INTERVENTIONS Comprehensive care included treatment from primary care clinicians and specialists in the same clinic with multiple features to promote prompt effective care. Usual care was provided locally in private offices or faculty-supervised clinics without modification. MAIN OUTCOMES AND MEASURES Primary outcome: children with a serious illness (death, ICU admission, or hospital stay >7 days), costs (health system perspective). Secondary outcomes: individual serious illnesses, medical services, Medicaid payments, and medical school revenues and costs. RESULTS In an intent-to-treat analysis, comprehensive care decreased both the rate of children with a serious illness (10 per 100 child-years vs 22 for usual care; rate ratio [RR], 0.45 [95% CI, 0.28-0.73]), and total hospital and clinic costs (

Comprehensive care reduced (per 100 child-years) serious illnesses (16 vs 44 for usual care; RR, 0.33 [95% CI, 0.17-0.66]), emergency department visits (90 vs 190; RR, 0.48 [95% CI, 0.34-0.67]), hospitalizations (69 vs 131; RR, 0.51 [95% CI, 0.33-0.77]), pediatric ICU admissions (9 vs 26; RR, 0.35 [95% CI, 0.18-0.70]), and number of days in a hospital (276 vs 635; RR, 0.36 [95% CI, 0.19-0.67]).

CONCLUSIONS AND RELEVANCE Among high-risk children with chronic illness, an enhanced medical home that provided comprehensive care to promote prompt effective care vs usual care reduced serious illnesses and costs. These findings from a single site of selected patients with a limited number of clinicians require study in larger, broader populations before conclusions about generalizability to other settings can be reached.

Anti-inflammatory effect of prophylactic macrolides on children with chronic lung disease: a protocol for a double-blinded randomised controlled trial

Abstract Objectives: Concerns have been raised regarding cardiac side effects of continuous high-dose albuterol nebulization in status asthmaticus management. Our study goal was to determine prevalence and potential risk factors for hypotension development during continuous albuterol administration in pediatric patients. Methods: A retrospective cohort study was conducted at Children’s Memorial Hermann Hospital from 1 January 2011 to 31 August 2012. A total of 152 patients admitted to pediatric intensive or intermediate care units who received continuous albuterol nebulization for management of status asthmaticus were analyzed. Results: Diastolic hypotension, defined as a value < 50 mmHg or <5th percentile of normal for age, developed in 90% of patients and a positive correlation with increasing doses of albuterol was demonstrated. The overall median time to onset of hypotension was 4 h (interquartile range (IQR): 2–6.5) and was significantly lower among patients admitted to the intensive care unit rather than intermediate care (p = 0.005). The odds of hypotension were 82% lower among patients who received fluid boluses prior to continuous albuterol nebulization. None of the potential risk factors demonstrated statistical significance. Conclusions: Diastolic hypotension is a common occurrence among patients who receive continuous albuterol nebulization for status asthmaticus. Total albuterol dose appeared to be directly related to risk of developing diastolic hypotension. Administration of supplemental fluid boluses before continuous nebulized albuterol appeared to provide a significant protective effect. The clinical impact and the significance of diastolic hypotension and the importance of prophylactic administration of intravenous fluid boluses in patients experiencing status asthmaticus are yet to be determined.
