Family tracing to identify patients with familial hypercholesterolaemia: the second audit of the Department of Health Familial Hypercholesterolaemia Cascade Testing Project.

BACKGROUND: Family tracing is a method recognized to find new patients with familial hypercholesterolaemia (FH). We have implemented family tracing led by FH Nurses and have determined acceptability to patients, feasibility and costs. METHODS: Nurses were located at five National Health Service (NHS) Trusts; they identified FH patients and offered them family tracing. Responses and test results were recorded on a database and summarized on a family pedigree. RESULTS: The majority ( approximately 70%) of index cases participated; the proportion was lower when patients had been discharged from the clinics and in metropolitan areas. On average, 34% (range 13-50%) of relatives lived outside the catchment area of the clinics and could not attend the nurse-led FH clinics. Of the previously untested relatives, 76% who lived in the catchment area of the clinic came forward to be tested. One-third of the relatives who came forward for testing were children

Are patients with familial hypercholesterolaemia well managed in lipid clinics? An audit of eleven clinics from the Department of Health Familial Hypercholesterolaemia Cascade Testing project.

BACKGROUND: Familial hypercholesterolaemia (FH) is an autosomal co-dominant disorder which is relatively common, leads to high levels of LDL-cholesterol and if untreated to early coronary heart disease. An audit of current practice at National Health Service Trusts in England was undertaken to determine whether FH patients meet the diagnostic criteria for FH; are being offered appropriate advice and treatment; and to what extent their families are contacted and offered testing for the disorder. METHODS: Medical records of known FH patients (over 18 years of age and diagnosed before 31 December 2003) were accessed to obtain information on diagnosis, treatment and family tracing. RESULTS: The records of 733 FH patients were examined, 79% met the UK 'Simon Broome' register criteria for the diagnosis of definite or possible FH. Analyses showed that patients were usually offered appropriate advice and treatment, with 89% being on a statin. However, the audit indicated a high variability in family tracing between the sites, with significant differences in the frequency of inclusion of a family pedigree in the notes (range 1-71%, mean 35%); the general practitioner (GP) being advised that first-degree relatives should be tested (range 4-52%, mean 27%); and the proportion of relatives contacted and tested (range 6-50%, mean 32%). CONCLUSION: FH patients are well cared for in lipid clinics in England, are being given appropriate lifestyle advice and medication, but an increase in recording of LDL-cholesterol levels may lead to improvements in their management. Practice in family tracing appears to vary widely between clinics.

Association of the metabolic syndrome with both vigorous and moderate physical activity.

BACKGROUND: Cross-sectional relationships between moderate and vigorous physical activity and the metabolic syndrome (MS) were examined in the Whitehall II study of civil servants (age 45-68 years). We assessed cardiovascular fitness and body mass index (BMI) as possible mediators of the observed association. METHODS: Measures of 2-hour glucose, systolic blood pressure, fasting triglycerides, waist-hip ratio, and high density lipoprotein (HDL) cholesterol were obtained in 5153 white European participants. Participants in the most adverse sex-specific quintile for three or more of these risk factors were classified as having MS. Self-reported leisure-time physical activity was categorized into separate moderate and vigorous activity classes. BMI and resting heart rate (HR) were used to estimate body fatness and cardiovascular fitness respectively. RESULTS: The odds ratios (95% CI) for having the metabolic syndrome in the top categories of vigorous and moderate activity were 0.52 (95% CI: 0.40, 0.67) and 0.78 (95% CI: 0.63, 0.96) respectively, adjusted for age, sex, smoking, alcohol intake, socioeconomic status, and other activity. Adjustment for BMI and resting HR substantially attenuated both of the above associations. CONCLUSIONS: Moderate and vigorous physical leisure-time activity are each associated with reduced risk of being classified with MS independently of age, smoking, and high alcohol intake. Both vigorous and moderate activities may be beneficial to the MS cluster of risk factors among middle-aged populations. Reduced BMI and increased cardiovascular fitness may be important mediators of this association for both intensities of activity.

Impact of long-term care of children assisted by technology on maternal health.

This study examines the health outcomes of mothers of children assisted by technology and their associations with condition severity and family and social support. The 6-month postdischarge status of 65 mothers of children assisted by technology was compared with that of 54 mothers of children (matched for age and sex) hospitalized for acute illnesses. We measured maternal health, emotional well-being (Center for Epidemiologic Studies Depression Scale), severity of the child's condition, family functioning, social support, and sociodemographic data. Mothers in the study group reported impaired health related to pain, vitality, social functioning, and mental health and substantially more depressive symptoms than mothers in the control group (p < .001), with almost half having scores suggesting clinical depression. Family supportiveness and opportunities for recreational and cultural activities were significantly lower in families with children assisted by technology. After controlling for sociodemographic variables, high condition severity (p < .01), lack of family support (p = .05), low social support appraisal (p < .01), and high levels of receipt of social support (p < .01) were associated with more depressive symptoms of mothers in the study group. Six months after diagnosis or major hospitalization, the severity of the condition was highly associated with maternal emotional well-being, with family support and social support appraisal having moderate independent positive effects. The receipt of social support indicated need rather than support and was negatively associated with well-being. Discharge planning and support systems need to focus on both the child and the prevention of secondary social and psychological morbidity of caretakers.

Concerns about child maltreatment in hospitalized children.

This study examined factors associated with clinicians' concerns about abuse and neglect and reporting hospitalized children to Child Protective Services (CPS). Data came from a cross-sectional chart review from a random sample of pediatric hospitalizations 1988-1990 in three cities for five condition groups (n = 5,446), and included evidence of clinicians' concerns about physical abuse or neglect and reports to CPS, family income, ethnicity, family structure, child's age, and illness severity at admission. Concerns about abuse were noted in 2.5% of the total sample, concerns about neglect in 3.1%, and 2.9% of children were reported to CPS. Concerns about abuse were most frequent in children with head trauma (8.2%), and concerns about neglect in children with toxic ingestion (12.3%). Young age of child, low income, and single parent family were independently associated with increased frequencies of concerns and reports. Low income was significantly associated with clinicians' concerns about neglect, but not abuse or reports to CPS. Ethnicity was not significant after controlling for income and family structure. Severity of illness was associated with concerns about physical abuse (p = .02) among children with head trauma, and with concerns about neglect and frequency of reporting among children with meningitis (p < .01). Our results confirm the associations among neglect, poverty, and single-parent families among hospitalized children. Increasing severity of illness may make clinicians consciously or unconsciously consider that care has been delayed and the child neglected.

Does quality of care affect rates of hospitalization for childhood asthma?

BACKGROUND: Hospitalization rates for childhood asthma are three times as high in Boston, Massachusetts, as in Rochester, New York; New Haven, Connecticut, rates are intermediate. We undertook this study to determine how care for children admitted for asthma varies across these communities. METHODS: We performed a community-wide retrospective chart review. We reviewed a random sample of all asthma hospitalizations, from 1988 to 1990, of children 2 to 12 years old living in these communities (n = 614). Abstracted data included demographics, illness severity, and treatment before admission. RESULTS: Compared with Rochester children, Boston children were less likely to have received maintenance preventive therapy (inhaled corticosteroids or cromolyn [odds ratio (OR), 0.4 (0.2, 0.9)]), acute "rescue" therapy (oral corticosteroids [OR, 0.2 (0.1, 0.4)]), or inhaled beta-agonist therapy [OR, 0.5 (0.3, 1.0)]. A larger proportion of admitted asthmatic patients in Boston (34%) were in the least severely ill group-oxygen saturation 95% or above-compared with patients in Rochester (20%). CONCLUSIONS: The quality of ambulatory care, including choice of preventive therapies and thresholds for admission, likely plays a key role in determining community hospitalization rates for chronic conditions such as childhood asthma.

Primary care involvement among hospitalized children.

OBJECTIVE: To examine relations between characteristics of a child's usual source of primary care and involvement of that source before and during hospitalization. DESIGN: Medical record review of pediatric hospitalizations. SETTING: All hospitals in Boston, Mass; New Haven, Conn; and Rochester, NY admitting children during the calendar years 1988 through 1990. PATIENTS: The study included 1875 randomly selected pediatric hospitalizations for five diagnostic groups (i.e., asthma and other lower respiratory tract disease, abdominal pain [including appendicitis], meningitis [bacterial and viral], toxic ingestions, and head injury). Hospital records selected were limited to children aged between 1 month and 12 years and residing in the three study communities. OUTCOME MEASURES: Whether the primary care source examined the child before admission to the hospital, referred the child to the emergency department, or served as the in-hospital attending physician. RESULTS: Of the medical charts reviewed, 85.7% identified primary care sources. Children in Rochester had higher rates of medical visits before admission (P < .04), referrals (P < .001), and in-hospital care provided by the primary care physician (P < .001, chi 2) than children in Boston and New Haven. Patterns of primary care involvement also varied by source of care within cities, after controlling for income and severity of illness. Compared with children from Rochester community-based private practices, children in Boston receiving care from health centers, hospitals, or community-based private practices generally had 25% to 50% lower likelihood of positive findings on all primary care involvement measures. Children in New Haven receiving care from community-based private or hospital-based practices also had lower rates, but involvement rates were not higher when they received care from health centers. Other children in Rochester and children receiving care from health maintenance organizations in all cities demonstrated almost no significant differences compared with data from Rochester community practices. CONCLUSION: The source of primary care is associated with patterns of prehospital and hospital care among hospitalized children, although specific associations vary by city.
