Associations Between Parental Health Literacy, Use of Asthma Management Plans, and Child's Asthma Control.

BACKGROUND: There are some studies demonstrating the effectiveness of the provision of written asthma action plans in improving asthma outcomes. There exist little data on the ability of parents to use these plans to make asthma care decisions. OBJECTIVE: To assess the associations between parental health literacy (HL), parental ability to use a written asthma management plan (WAMP), and child's asthma control. METHODS: Parents completed a survey with questions related to WAMPs and child's asthma, a HL screening tool, and 5 asthma vignettes. For vignettes, parents identified asthma control zone and then made decisions about asthma management. WAMP scores were totaled (0-32) and converted to a percent correct score. Associations between parental HL, WAMP scores, child's asthma control, and demographics were determined with independent t tests or 1-way analysis of variance, and chi-square tests. Variables significantly associated with WAMP scores or asthma control were included in multiple logistic regression or multiple linear regression analyses. RESULTS: A total of 176 surveys were included; the mean ± SD WAMP score was 58.9% ± 22.2%, and 25% of respondents had limited HL. Of respondents' children, 38% had not well/poorly controlled asthma. In multiple regression analysis controlling for education level, limited HL was significantly associated with WAMP score (b = 11.3, standard error 3.8, P = .004). WAMP score was not associated with asthma control. Limited HL was associated with poor asthma control in univariate analysis, but not in a logistic regression model controlling for other significant variables. Only unmarried marital status (adjusted odds ratio 4.4, 95% CI 1.8-10.8, P = .001) was associated with asthma control. CONCLUSION: HL is associated with parental ability to use WAMPs to respond to asthma scenarios. Parental HL may play a role in parents' ability to appropriately use WAMPs.

The prevalence of incidental findings on abdominal computed tomography scans of trauma patients.

BACKGROUND: Abdominal computed tomography scanning (AbdCTS) is the standard of care in the evaluation of blunt trauma patients. The liberal use of AbdCTS coupled with advancing imaging technology often results in the detection of incidental findings. OBJECTIVES: We sought to characterize the incidence and prevalence of such findings, describe the lesions most frequently seen on AbdCTS performed on patients admitted to a Level I trauma center, and develop a plan for follow-up through our performance improvement process. METHODS: AbdCTS reports of all admissions to a Level I trauma center between January 2000 and December 2002 were reviewed. Incidental findings identified were classified into benign anatomic variants, benign pathologic lesions, and pathologic lesions requiring further work-up. RESULTS: A total of 3,113 patients were evaluated by AbdCTS during this time period. There were 1474 incidental findings in 1,103 patients. Seventy-five percent of patients with incidental lesions had no traumatic findings. Benign anatomic variants were present in 1.8%, benign pathologic findings in 27.5%, and pathologic findings requiring work-up in 6.1%. Congenital renal anomalies and duplicate inferior vena cava were the most common benign anatomical findings. Renal and hepatic cysts were the most frequent benign lesions and non-calcified pulmonary nodules and adrenal masses were the pathologic lesions most commonly seen. CONCLUSIONS: Incidental findings are seen in up to 35% of trauma AbdCTS. No concomitant traumatic injuries are present in up to 75% of these patients. Protocols for appropriate intervention or arrangements for follow-up care need to be incorporated into the care of the trauma patients.
