Do Patients of Subspecialist Physicians Benefit from Written Asthma Action Plans?

RATIONALE: Asthma clinical guidelines suggest written asthma action plans are essential for improving self-management and outcomes. OBJECTIVES: To assess the efficacy of written instructions in the form of a written asthma action plan provided by subspecialist physicians as part of usual asthma care during office visits. METHODS: A total of 407 children and adults with persistent asthma receiving first-time care in pulmonary and allergy practices at 4 urban medical centers were randomized to receive either written instructions (n = 204) or no written instructions other than prescriptions (n = 203) from physicians. MEASUREMENTS AND MAIN RESULTS: Using written asthma action plan forms as a vehicle for providing self-management instructions did not have a significant effect on any of the primary outcomes: (1) asthma symptom frequency, (2) emergency visits, or (3) asthma quality of life from baseline to 12-month follow-up. Both groups showed similar and significant reductions in asthma symptom frequency (daytime symptoms [P < 0.0001], nocturnal symptoms [P < 0.0001], ß-agonist use [P < 0.0001]). There was also a significant reduction in emergency visits for the intervention (P < 0.0001) and control (P < 0.0006) groups. There was significant improvement in asthma quality-of-life scores for adults (P < 0.0001) and pediatric caregivers (P < 0.0001). CONCLUSIONS: Our results suggest that using a written asthma action plan form as a vehicle for providing asthma management instructions to patients with persistent asthma who are receiving subspecialty care for the first time confers no added benefit beyond subspecialty-based medical care and education for asthma.

A comparison of bronchoalveolar lavage versus lung biopsy in pediatric recipients after stem cell transplantation.

Bronchoalveolar lavage (BAL) has been a useful initial diagnostic tool in the evaluation of pulmonary complications after hematopoietic stem cell transplantation (HSCT); however, the diagnostic sensitivity, prevalence, and outcome after BAL versus lung biopsy (LB) in pediatric HSCT patients remains to be determined. We reviewed 193 pediatric HSCT recipients who underwent a total of 235 HSCTs. Sixty-five patients (34%) underwent a total of 101 BALs for fever, respiratory distress, and/or pulmonary infiltrates on chest radiograph and/or computed tomography scan. The 1-year probability of undergoing BAL was 43.0% after allogeneic stem cell transplantation (alloSCT) and 8.5% after autologous stem cell transplantation (autoSCT) (P = .001). Sixteen of the 193 patients (8%) patients underwent 19 LBs. The probability of undergoing LB at 1 year after HSCT was 9.3%. No grade III or IV adverse events related to either procedure were observed. Of the 101 BALs performed, 40% (n = 40) were diagnostic, with a majority revealing a bacterial pathogen. Among the 19 LBs performed, 94% identified an etiology. In multivariate analysis, myeloablative conditioning alloSCT conferred the highest risk of requiring a BAL (hazard ratio [HR],8.5; P = .0002). The probability of 2-year overall survival was 20.2% in patients who underwent BAL, 17.5% for patients who underwent biopsy, and 67.4% for patients who had neither procedure. In multivariate analysis, only the requirement of a BAL was independently associated with an increased risk of mortality (HR, 2.96; P < .0001). In summary, in this cohort of pediatric HSCT recipients, BAL and LB were used in approximately 35% and 8% of pediatric HSCTs with diagnostic yields of approximately 40% and 94%, respectively, and were both associated with poor long-term outcomes.

Massive pulmonary embolism in children.

We present 3 children with massive pulmonary embolism and review 17 recent pediatric reports. Malignancies were a frequent cause (40%), and sudden death was common (60%). Compared with adults, diagnosis was more likely to be made at autopsy (P < .0001), more children were treated with embolectomy/thrombectomy (P = .0006), and mortality was greater (P = .03).

A retrospective cohort study of pulmonary function, radiographic measures, and quality of life in children with congenital scoliosis: an evaluation of patient outcomes after early spinal fusion.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: The purpose of this study is to evaluate pulmonary function and quality of life (QOL) in children treated with early spinal fusion for progressive congenital scoliosis. SUMMARY OF BACKGROUND DATA: The relationships between radiographic measures, pulmonary function tests (PFT), and QOL were examined. METHODS.: Twenty-one patients with congenital scoliosis treated with early spinal fusion were evaluated using radiographs, PFT, and the Child Health Questionnaire (CHQ) at 12.6 +/- 3.5 years. They were 6.9 +/- 2.3 years postdefinitive fusion, which occurred at 4.9 +/- 3.1 year of age. The cohort was also divided in two groups, "thoracic fusion" (apex above the thoracolumbar T-L junction) and "nonthoracic fusion" (below T-L junction). RESULTS: Forced vital capacity, forced expiratory volume (FEV1), vital capacity (P < 0.0001), and total lung capacity (P = 0.017) were significantly lower compared with healthy children. CHQ scores were significantly lower than in healthy children in physical function (P = 0.036), general health (P = 0.007), physical summary (P = 0.026), and parental impact/emotional (P = 0.01). Correlation analysis showed that the degrees of thoracic curves were negatively correlated with FEV1 (P < 0.05), family activities, role/social physical (P < 0.05), and physical summary (P < 0.01). The degree of kyphosis was negatively correlated with Self-Esteem (P < 0.01). Patients who had thoracic fusions had shorter spinal height (P = 0.049), lower forced vital capacity (P = 0.004), FEV (P = 0.012), vital capacity (P = 0.031), and reported more pain (P = 0.033) than nonthoracic fused. CONCLUSION: Compared with healthy peers, congenital scoliosis patients treated with early spinal fusion have worse PFT and QOL scores at 6.9 years follow up. Patients with thoracic fusions had shorter spines, worse pulmonary function, and more pain than nonthoracic fused. The results may support alternatives to early spinal fusion such as growing rods, epiphysiodesis, and distraction thoracoplasty. Current efforts are underway to compare outcomes of this study to those of other treatments.
