Caring for the underserved: blending service learning and a web-based curriculum.

BACKGROUND: Recognition of health disparities among underserved individuals, whose demographic, geographic, or economic characteristics impede access to health-related services, has led to calls for the development of medical school curricula that address care for the underserved, but reports of the development and evaluation of such curricula are limited. METHODS: Two formats of a curriculum addressing care for the underserved were developed and implemented during the 6-week pediatric clerkship for third-year medical students during the 2003-2004 academic year. One format was faculty-led; the other was web-based. Skills for providing care to underserved families were taught through didactic, experiential, and service-learning curriculum components. Novel core curriculum elements included a screening tool for recognizing underserved patients and an independent clinical project through which students linked underserved families with community health resources. Analyses from 2004-2005 compared pre- and post-curriculum knowledge and attitudes of web-based students (n = 29) to those receiving either the faculty-led (n = 36) or the established "readings-only" curriculum (n = 35). Qualitative data from service learning projects were analyzed to assess clinical skills. RESULTS: Compared to students in the established curriculum, both web-based and faculty-led students demonstrated improved knowledge (p < 0.001) and attitudes (p < 0.05) about caring for the underserved. Both web-based and faculty-led students were successful in recognizing and addressing underserved health issues in the clinical setting. CONCLUSIONS: Faculty-led and web-based curricula can equally improve student knowledge, attitudes, and skills about caring for the underserved.

Newborn screening for cystic fibrosis: parents' preferences regarding counseling at the time of infants' sweat test.

Newborn screening (NBS) protocols for cystic fibrosis (CF) are the first regional population-based programs to incorporate DNA analysis into their procedures. Research about these programs can inform policy and practice regarding how best to counsel families with abnormal NBS results. The grounded theory method guided interviews with 33 families whose infants had abnormal CF NBS results. A dimensional analysis of these interviews provided a theoretical framework describing parents' preferences regarding counseling during their infant's sweat test appointment. This framework describes the contexts and characteristics of the two main dimensions of parents' preferences: factual information and emotional support. Factual information included learning about the probability of a CF diagnosis, CF disease facts, sweat test procedure, and CF genetics. Social support consisted of offering parents a choice about the timing and amount of CF information, showing empathy for their distress, instilling hope, personalizing counseling, and providing hospitality. This framework also explains the consequences of counseling that matched versus mismatched parental preferences in these domains. Counseling that matched parents preferences reduced parents' distress while mismatched counseling tended to increase parents' worry about their infant.

Preventing early, prolonged vitamin E deficiency: an opportunity for better cognitive outcomes via early diagnosis through neonatal screening.

OBJECTIVE: To evaluate whether early diagnosis of cystic fibrosis (CF) through newborn screening (NBS) and early vitamin E status are associated with cognitive function. STUDY DESIGN: We assessed cognitive function for 71 children without meconium ileus (ages 7.3-16.9 years) enrolled in the screened (S) or control (C) group of the Wisconsin CF Neonatal Screening Project. The Test of Cognitive Skills, 2nd edition generated the cognitive skills index (CSI; mean = 100, SD = 16). Vitamin E deficiency at diagnosis was defined as plasma alpha-tocopherol (alpha-T) below 300 microg/dL (<300E). Primary analyses evaluated CSI scores across the 4 levels of group (S or C) by using alpha-T status (<300E or >300E) with analysis of covariance. RESULTS: After adjusting for covariates, CSI in the C<300E group was significantly lower than each of the other groups (C>300E, S<300E, and S>300E; P < .05). The highest proportion of CSI scores >84 occurred in the C<300E group (41%). Patients in this group also had the lowest mean head circumference z-scores at diagnosis. CONCLUSIONS: Our results show that prolonged alpha-T deficiency in infancy is associated with lower subsequent cognitive performance. Thus, diagnosis via NBS may benefit the cognitive development of children with CF, particularly in those prone to vitamin E deficiency during infancy.

Quality of life of children with cystic fibrosis.

OBJECTIVE: To review health-related quality of life (QOL) and associated issues and to describe a study investigating "Child Health Questionnaire" (CHQ) scores in relationship to newborn screening (NBS) for cystic fibrosis (CF) and markers of disease severity. METHODS: A total of 36 patients from 10-15.5 years old who were enrolled in the screened or control group of the Wisconsin CF Neonatal Screening Project completed the CHQ. Scale scores comprised the dependent variables. Independent variables included study group and measures of disease severity. Analyses included Fisher's exact, 2-sample Wilcoxon, and t tests. RESULTS: QOL did not differ significantly between the screened and control groups for any of the scales. None of the comparisons of CHQ scale scores across measures of disease severity were significant in this small sample, but the CHQ and power were limiting. CONCLUSIONS: Our results did not demonstrate a benefit of CF NBS on QOL; however, the CHQ may not be adequately sensitive to QOL in children with CF with disease severity comparable to our sample. The Cystic Fibrosis Questionnaire, a recently validated CF-specific QOL measure for pediatric samples, is likely to provide a more informative evaluation of the effects of CF NBS on patients' QOL.

Psychosocial risk associated with newborn screening for cystic fibrosis: parents' experience while awaiting the sweat-test appointment.

BACKGROUND: The psychosocial effects on parents of infants with abnormal results in cystic fibrosis (CF) newborn screening (NBS) that uses genetic testing remain unclear. METHODS: Twenty-eight individuals representing 14 families participated in grounded theory interviews approximately 6 months after their child's positive NBS results for CF. Participants also completed the Center for Epidemiologic Studies Depression Scales (CES-D) at their infant's sweat-test appointment (n = 51) and/or approximately 6 months after the sweat test (n = 35). RESULTS: Most parents experienced high levels of emotional distress during their wait for the sweat-test appointment (CES-D score, mean +/- SD: 16.5 +/- 6.7; 43.1% in the clinical range; median wait: 7 days; range: 3-35 days). CES-D scores of these parents were also significantly higher than those of comparison parents. Interviews showed that parental cognitive uncertainty and emotional distress were influenced by the parents' prior knowledge of NBS, CF, and their carrier status; parents' adjustment to their new baby; and the physicians' approach to informing parents. Parents' coping strategies involved requesting a sweat test as soon as possible, searching for information, assessing the infant's risk/health, seeking support, praying, or not talking with others. CONCLUSIONS: The waiting period from notification regarding positive NBS results to diagnostic test results can be psychologically distressing to parents, causing depressive symptoms that vary depending on their perceptions about the likelihood that their infant has CF. Implications for future research examining psychosocial interventions for NBS are discussed.

Cognitive function of children with cystic fibrosis: deleterious effect of early malnutrition.

OBJECTIVE: Patients who have cystic fibrosis (CF) and experience delayed diagnosis by traditional methods have greater nutritional insult compared with peers diagnosed via neonatal screening. The objective of this study was to evaluate cognitive function in children with CF and the influence of both early diagnosis through neonatal screening and the potential effect of early malnutrition. METHODS: Cognitive assessment data were obtained for 89 CF patients (aged 7.3-17 years) during routine clinic visits. Patients had been enrolled in either the screened (N = 42) or traditional diagnosis (control) group (N = 47) of the Wisconsin CF Neonatal Screening Project. The Test of Cognitive Skills, Second Edition was administered to generate the Cognitive Skills Index (CSI) and cognitive factor scores (Verbal, Nonverbal, and Memory). RESULTS: Cognitive scores in the overall study population were similar to normative data (CSI mean [standard deviation]: 102.5 [16.6]; 95% confidence interval: 99.1-105.9). The mean (standard deviation) CSI scores for the screened and control groups were 104.4 (14.4) and 99.8 (18.5), respectively. Significantly lower cognitive scores correlated with indicators of malnutrition and unfavorable family factors such as single parents, lower socioeconomic status, and less parental education. Our analyses revealed lower cognitive scores in patients with low plasma alpha-tocopherol (alpha-T) levels at diagnosis. In addition, patients in the control group who also had vitamin E deficiency at diagnosis (alpha-T < 300 microg/dl) showed significantly lower CSI scores in comparison with alpha-T-sufficient control subjects and both deficient and sufficient alpha-T subsets of screened patients. CONCLUSION: Results suggest that prevention of prolonged malnutrition by early diagnosis and nutritional therapy, particularly minimizing the duration of vitamin E deficiency, is associated with better cognitive functioning in children with CF.
