The Pediatric Bowel Management Clinic: initial results of a multidisciplinary approach to functional constipation in children.

The multifactorial nature of functional constipation in children suggests that a multidisciplinary management approach may be effective. The authors tested this hypothesis in a newly created pediatric Bowel Management Clinic (BMC). Detailed data were collected prospectively on all patients seen in the clinic over the first 16 months. Both quantitative and qualitative analyses were performed to describe the index population and to demonstrate the impact of the intervention. Satisfaction with care in the clinic was measured using the Measure of Processes of Care tool, then compared with a normative sample. One hundred fourteen patients, all previously treated unsuccessfully for constipation, were referred to a team comprised of a physician, nurse practitioner, nurse educator, dietitian, and psychosocial nurse specialist. The mean age was 5.4 years with equal gender distribution. Between the first and last visits recorded, several variables including stool consistency and frequency, soiling frequency, abdominal pain, rectal pain, and rectal bleeding all showed statistically significant (P < .05) improvement. Qualitative data analysis showed the significant psychosocial impact of constipation on patients and their families. In the Measures of Processes of Care questionnaire, scores for the BMC were higher than normal on all scales except in provision of information. A multidisciplinary approach to functional constipation leads to both patient and parent satisfaction and significant short-term improvement. Further studies will examine the long-term impact of the clinic.

Neuropsychological function in mild sleep-disordered breathing.

Although a broad range of neuropsychological deficits has been reported in patients with severe sleep disordered breathing (SDB), little is known about the impact of mild SDB on neuropsychological performance. In this study, we compared neuropsychological test performance in two groups of carefully screened volunteers who differed clearly according to the respiratory disturbance index (RDI). Controls (n = 20) were identified on the basis of an RDI < 5; cases (n = 32) had an RDI in the range of 10-30. Cases and controls were well matched with regard to IQ, age, and sex. Cases had significantly more self-reported snorting and apneas and a higher body mass index than controls but did not differ according to sleepiness as measured by either the multiple sleep latency test or the Epworth sleepiness scale. An extensive battery of neuropsychological and performance tests was administered after an overnight sleep study. Cases performed significantly more poorly on a visual vigilance task (perceptual sensitivity, d': 2.24 +/- 0.64 vs. 2.70 +/- 0.53, p = 0.01, for cases and controls, respectively) and a test of working memory, the Wechsler adult intelligence scale-revised digits backwards test (6.12 +/- 2.20 vs. 7.55 +/- 2.22, p = 0.02), than controls. The groups did not differ in their performance on other tests of memory, information processing, and executive functioning. In summary, subjects with mild SDB may manifest a vigilance deficit in the absence of substantial sleepiness. Subjects with a mildly elevated RDI (10-30) without sleepiness do not appear to suffer appreciable deficits in more complex neuropsychological processes (e.g. executive functions).

Racial differences in sleep-disordered breathing in African-Americans and Caucasians.

In this case-control family study of sleep-disordered breathing (SDB), we describe the distributions of SDB and SDB risk factors in African-Americans and Caucasians. A total of 225 African-Americans and 622 Caucasians, ages 2 to 86 yr, recruited as members of families with an individual with known sleep apnea (85 index families) or as members of neighborhood control families (63 families) were studied with an overnight home sleep-study, questionnaires, and physical measurements. A subsample underwent cephalometry. Outcome measures were the respiratory disturbance index (RDI) and a binary variable indicating the presence of increased apneic activity (IAA). In both races, a strong relationship was demonstrated between the (log transformed) RDI and age and age2. African-Americans with SDB were younger than Caucasians with SDB (37.2 +/- 19.5 versus 45.6 +/- 18.7 yr, p < 0.01). In subjects < or = 25 yr, RDI level and IAA prevalence were higher in African-Americans (odds ratio, adjusted for obesity, sex, proband sampling, and familial clustering, 1.88, 1.03 to 3.52, 95% CI). In this age group, racial differences also were observed in the relationship between RDI and age (p < 0.001 for the RDI-age interaction). This suggests that young African-Americans may be at increased risk for sleep apnea.

Effects of residence in Alzheimer disease special care units on functional outcomes.

CONTEXT: Alzheimer disease special care units (SCUs) in nursing homes are increasingly prevalent, but little is known about their effects on residents' outcomes. OBJECTIVE: To analyze the effect of SCU residence on the rates at which residents decline in functional status. DESIGN: A cohort of nursing home residents assessed at multiple points during about 1 year. Facility staff completed all assessments using the Minimum Data Set for Nursing Home Resident Assessment and Care Screening (MDS). SETTING: Medicare- or Medicaid-certified nursing facilities. PATIENTS OR OTHER PARTICIPANTS: All nursing home residents in 1993 and early 1994 in Kansas, Maine, Mississippi, and South Dakota. Serial MDS assessments of 77337 residents in more than 800 facilities, including 1228 residents in 48 facilities with SCUs. MAIN OUTCOME MEASURES: Decline in locomotion, transferring, toileting, eating, dressing, and a summary activities of daily living index; decline in urinary and bowel continence; and significant weight loss. RESULTS: No statistically significant difference was observed in the speed of decline for residents in SCUs and traditional units in any of the 9 outcomes. Residents were matched on a variety of characteristics, and subgroup analyses were performed. In none did we observe a pattern of better outcomes among SCU residents. CONCLUSIONS: Although SCUs may have provided unmeasured benefits to families and residents, it does not appear that those benefits included any slowing in the rates of functional decline experienced by individuals with dementia.
