RESUMEN

OBJECTIVE: This study was undertaken to determine the health and cost effects of using home care to treat newly diagnosed Type I diabetic children rather than traditional inpatient hospital care. There had been no well-designed evaluations of home care for such children, and very few for children with other health conditions. METHODS: Sixty-three children seen at the Montreal Children's Hospital were randomly assigned at diagnosis to home care or traditional inpatient care. The children in the former group were discharged once their metabolic condition stabilized; insulin adjustments and teaching were done in their homes by a trained nurse. The children in the latter group remained hospitalized for insulin adjustments and teaching. All were followed for 24 months. The cost effects were estimated using hospital and parental data. RESULTS: Social costs were only $48 higher with home care. It had little effect on social costs, because the increased costs of health care services with home care ($768) were largely offset by parental cost savings ($720). Home care improved the children's metabolic outcomes without adversely affecting their psychosocial outcomes. CONCLUSIONS: Using home care to reduce hospital stays for children with newly diagnosed Type I diabetes improved the children's health outcomes without significantly increasing social costs.

RESUMEN

Since 1971 pediatric mortality rates have decreased markedly but differently in Canada and the United States. These trends were examined in light of changes in hospital use and health care financing. Annual mortality and hospital use rates for children aged 14 years and younger were calculated. Between 1971 and 1987, all-cause mortality in Canada fell from 165 to 74 per 100,000; the American rate fell from 172 to 96 per 100,000. American hospitalization rates remained essentially constant until 1983 and then fell by 27.5%, while Canadian hospitalization rates declined throughout. In 1987 Canadian children had higher hospitalization rates, while American children had higher mortality rates. These differences may be associated with differences in health financing; the adoption of US prospective payment systems was temporally coincident with sharp declines in hospitalization rates for American children.

RESUMEN

OBJECTIVES: To determine whether seeking advice prior to an unscheduled visit to a pediatric emergency department (PED) influences appropriate use of this setting for minor illnesses. DESIGN: Cross-sectional questionnaire survey. SETTING: The medical emergency department of the Montreal (Quebec) Children's Hospital, a major referral and urban teaching hospital. PARTICIPANTS: Four hundred eighty-nine of 562 consecutive parents visiting the PED over two periods, one in February and the other in July 1989. INTERVENTIONS: None. MEASUREMENTS/MAIN RESULTS: Parents of children between 0 and 18 years of age visiting the PED were asked whether they had previously sought advice from family, friends, or a physician. Other factors possibly related to the decision to seek care were also measured. Appropriateness was rated, blind to discharge diagnosis, by two pediatricians using a structured series of questions incorporating the child's age, time of the visit, clinical state, and problem at presentation. Thirty-four percent of visits among respondents were judged appropriate. In bivariate analysis, appropriate visits occurred significantly more often when a parent spoke to both a physician and a nonphysician (47%) prior to visiting the PED than when no advice was sought (29%; P < .05). In multivariate analysis, having a regular physician and being one of two children also contributed to appropriateness. CONCLUSIONS: Appropriate use of the PED was positively influenced by seeking prior advice from both a physician and family member, having a regular physician, and having prior child care experience.

RESUMEN

Previous studies of fetal growth and body proportionality have been based on error-prone gestational age estimates and on inappropriate comparisons of infants with dissimilar birth weights. Based on a cohort of 8719 infants with validated (by early ultrasonography) gestational ages and indexes of body proportionality standardized for birth weight, potential maternal and fetal determinants of fetal growth and proportionality were assessed. Maternal history of previous low birth weight infants, pregnancy-related hypertension (particularly if severe), diabetes, prepregnancy weight, net gestational weight gain, cigarette smoking, height, parity, and fetal sex were all significantly associated with fetal growth in the expected directions. Consistent with previous reports, maternal age, marital status, and onset or total amount of prenatal care had no significant independent effects. Fetal growth ratio (relative weight for gestational age), pregnancy-related hypertension, fetal sex, and maternal height were the only significant determinants of proportionality. Infants who were growth-retarded, those with taller mothers, those whose mothers had severe pregnancy-related hypertension, and males tended to be longer and thinner and had larger heads for their weight, although these variables explained only a small fraction of the variance in the proportionality measures. Among infants with intrauterine growth retardation, gestational age was not independently associated with proportionality (in particular, late term and post-term infants did not tend to be more disproportional), a finding that does not support the hypothesis that earlier onset of growth retardation leads to more proportional growth retardation. The results raise serious questions about previous studies of proportionality, particularly those suggesting a nutritional etiology for proportional intrauterine growth retardation.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMEN

Neuroblastoma is the most common fatal solid tumour of childhood. Studies in Japan suggest that screening urine at 6 months for tumour-derived metabolites greatly improves early case finding and prognosis. The incidence rate of neuroblastoma in Quebec is at least 1 per 10,330 live births, higher than that of all other diseases responding to early treatment except congenital hypothyroidism screened for in the Quebec Network of Genetic Medicine. The feasibility of chemical screening of urine for elevated levels of homovanillic acid and vanillylmandelic acid in Quebec was assessed. The cost-effectiveness of screening 100,000 infants per year would be high (cost-benefit ratio 2.4), with a net saving of about $280,000 and eight lives per year. The estimated cost of adding neuroblastoma screening to the existing urine metabolite screening program is $70,700. The apparent sensitivity of the proposed test is 0.859 and the rate of false-positive results about 0.1%, both acceptable values. The attitude of potential participants toward the present urine screening program and the addition of a "tumour test" was positive. The results indicate that a pilot study of neuroblastoma screening in Quebec could be undertaken.
