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.

Pediatric guidelines: help or hindrance?

Guidelines are an increasingly prominent part of the practice of pediatrics. Aiming from studies of variability in care, they are widely used as a mechanism to assess and improve quality. Rigorous methods of guideline development differentiate current guidelines from past consensus efforts. The American Academy of Pediatrics has been active in developing and publishing guidelines for common problems, including asthma, hyperbilirubinemia, febrile seizures, gastroenteritis, and, together with the Agency for Health Care Policy and Research and others, otitis media with effusion. Although strategies for how to use guidelines to improve care are increasingly well designed, whether these guidelines will indeed change practice or improve outcomes has yet to be determined.

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.

Quality of care for preschool children with asthma: the role of social factors and practice setting.

OBJECTIVE: To determine whether patient race or source of payment is associated with differences in the quality of inpatient and outpatient treatment for young children with asthma. DESIGN: Structured medical record review. SETTING: Tertiary care pediatric hospital. PATIENTS: We studied 354 patients aged 1 to 6 years discharged with asthma between October 1, 1989 and September 30, 1990. MEASURES: We developed indicators of the quality of asthma care provided before and during hospitalization and planned after discharge. Outpatient indicators were the use of inhaled beta-agonists and the use of preventive anti-inflammatory medications (inhaled steroids or cromolyn sodium) before admission. In-hospital indicators were the intensity of inhaled beta-agonist therapy in the emergency department and length of stay. Planning for post-hospital care was assessed by the prescription of a nebulizer for home use. We examined associations between these indicators and patient race and source of payment, and explored the influence of primary-care practice type on these associations. RESULTS: After adjustment for potential confounders, we found that Hispanic patients were less likely than white patients to have taken inhaled beta-agonists before admission. Both black and Hispanic patients were less likely than white patients to have taken anti-inflammatory medications. When we adjusted for the patients' primary-care practice type, the effect of patient race did not persist for these indicators of outpatient care. We found no differences by patient race in emergency department care or length of hospital stay. However, black and Hispanic patients were much less likely to be prescribed a nebulizer for home use upon discharge. After adjustment for confounders, there were no differences in the quality of asthma care by source of payment. CONCLUSIONS: We found that young children of racial minorities admitted for an asthma exacerbation were less likely to have received maximally effective preventive therapy. We also identified marked differences in the quality of care planned after hospital discharge for black and Hispanic patients, compared with white patients. Particularly in an era of health reform, attention should focus on barriers to high-quality care for underserved children, who are already at high risk for asthma-related morbidity.

Work-related physical exertion and risk of preterm, low birthweight delivery.

Although many women work during pregnancy, the effect of maternal job experience on pregnancy outcome is controversial. We investigated whether work-related physical exertion increases a woman's risk of delivering a preterm, low birthweight infant. We studied 773 employed, pregnant women included in the National Longitudinal Survey of Labor Market Experience, Youth Cohort (NLSY), a nationally representative sample of young adults. Data concerning work status, job title during pregnancy, and other factors affecting the outcome of pregnancy were obtained from the NLSY. Assessment of physical exertion was based on job title, using an established catalogue of occupational characteristics. Women in jobs characterised by high physical exertion experienced a higher rate of preterm, low birthweight delivery, defined as maternal report of delivery more than 3 weeks early and birthweight under 2,500 g (adjusted RR = 5.1, 95% CI = 1.5, 17.7). These findings support a policy of limiting work-related physical exertion during pregnancy.

Work-related psychosocial stress and risk of preterm, low birthweight delivery.

We investigated whether work-related psychologic stress--defined as work characterized by both high psychologic demands and limited control over the response to these demands--increases a woman's risk of delivering a preterm, low birthweight infant. We studied 786 employed pregnant women included in the National Longitudinal Survey of Labor Market Experience, Youth Cohort (NLSY), a nationally representative sample of 12,686 young adults. Data concerning work status, job title, and other factors affecting pregnancy outcome were obtained from the NLSY. Assessment of job experience was based on job title, using an established catalogue of occupation characteristics. After accounting for the physical exertion entailed in a job, occupational psychologic stress as measured by job title was not associated with preterm, low birthweight delivery for the sample as a whole (Relative risk = 1.16, 95% confidence interval .45, 2.95). For those women who did not want to remain in the work force, work-related stress increased their risk of experiencing this outcome (RR = 8.1, 95% CI 1.5, 50.2). Personal motivation toward work, as well as the physical effort of work, should be considered in evaluating the impact of a job's psychologic characteristics on pregnancy outcome.

Variations in rates of hospitalization of children in three urban communities.

Hospitalization accounts for a large portion of the expenditures for child health care, and differences in the rate of hospitalization may produce important variations in the cost of that care. We studied the rates of hospitalization in Boston, Rochester (N.Y.), and New Haven (Conn.) in 1982. We assigned the risk of hospitalization in Rochester a score of 1.00. Boston children were hospitalized at more than twice the rate of Rochester children for most medical diagnostic categories (relative risk, 2.65; 95 percent confidence interval, 2.53 to 2.78), and the rate for the New Haven group was intermediate (relative risk, 1.80; 95 percent confidence interval, 1.68 to 1.93). Rates of inpatient surgery differed less (Boston relative risk, 1.12; New Haven relative risk, 0.93). The relative risks of hospitalization (as compared with Rochester children) for Boston and New Haven children, respectively, were 3.8 and 2.3 for asthma, 6.1 and 2.9 for toxic ingestions, and 2.6 and 2.7 for head injuries. Fractures of the femur, appendicitis, and bacterial meningitis (conditions uniformly treated in the hospital) had similar rates of hospitalization across the three cities, but the relative risk of hospitalization for aseptic meningitis was 3.7 in Boston. The rates of hospitalization of children in all three communities were below the national averages in 1982. Although this study does not define the reasons for the variation in rates of hospitalization, it is possible that they were related in part to differences in socioeconomic status or access to primary care. The implications of these data for the cost and quality of pediatric care therefore remain to be determined.

Universal newborn hearing screening: summary of evidence.

CONTEXT: Each year, approximately 5000 infants are born in the United States with moderate-to-profound, bilateral permanent hearing loss (PHL). Universal newborn hearing screening (UNHS) has been proposed as a means to speed diagnosis and treatment and thereby improve language outcomes in these children. OBJECTIVES: To identify strengths, weaknesses, and gaps in the evidence supporting UNHS and to compare the additional benefits and harms of UNHS with those of selective screening of high-risk newborns. DATA SOURCES: We searched the MEDLINE, CINAHL, and PsychINFO databases for relevant articles published from 1994 to August 2001, using terms for hearing disorders, infants or newborns, screening, and relevant treatments. We contacted experts and reviewed reference lists to identify additional articles, including those published before 1994. STUDY SELECTION: We included controlled and observational studies of (1) the accuracy, yield, and harms of screening using otoacoustic emissions (OAEs), auditory brainstem response (ABR), or both in the general newborn population and (2) the effects of screening or early identification and treatment on language outcomes. Of an original 340 articles identified, 19 articles, including 1 controlled trial, met these inclusion criteria. DATA EXTRACTION: Data on population, test performance, outcomes, and methodological quality were extracted by 2 authors (D.C.T., H.M.) using prespecified criteria developed by the US Preventive Services Task Force. We queried authors when information needed to assess study quality was missing. DATA SYNTHESIS: Good-quality studies show that from 2041 to 2794 low-risk and 86 to 208 high-risk newborns were screened to find 1 case of moderate-to-profound PHL. The best estimate of positive predictive value was 6.7%. Six percent to 15% of infants who are missed by the screening tests are subsequently diagnosed with bilateral PHL. In a trial of UNHS vs clinical screening at age 8 months, UNHS increased the proportion of infants with moderate-to-severe hearing loss diagnosed by age 10 months (57% vs 14%) but did not reduce the rate of diagnosis after age 18 months. No good-quality controlled study has compared UNHS with selective screening of high-risk newborns. In fair- to poor-quality cohort studies, intervention before age 6 months was associated with improved language and communication skills by ages 2 to 5 years. These studies had unclear criteria for selecting subjects, and none compared an inception cohort of low-risk newborns identified by screening with those identified in usual care, making it impossible to exclude selection bias as an explanation for the results. In a mathematical model based on the literature review, we estimated that extending screening to low-risk infants would detect 1 additional case before age 10 months for every 1441 low-risk infants screened, and result in treatment before 10 months of 1 additional case for every 2401 low-risk infants screened. With UNHS, 254 newborns would be referred for audiological evaluation because of false-positive second-stage screening test results vs 48 for selective screening. CONCLUSIONS: Modern screening tests for hearing impairment can improve identification of newborns with PHL, but the efficacy of UNHS to improve long-term language outcomes remains uncertain.

Work-family issues and perceptions of stress among pediatric faculty and house staff.

OBJECTIVES: To examine work-family balance issues and predictors of stress related to work-family balance among pediatric house staff and faculty. METHODS: Data were obtained through an anonymous mail survey. Univariate analyses assessed associations between work-family issues (work-related factors that affect work-family balance, perceived support, work-family--related stress, and proposed solutions) and the following variables: gender, parental status, working status of spouse, and academic rank. Multiple linear regression examined independent predictors of perceived stress. RESULTS: Fifty percent of the 327 respondents cared for dependent children, and 20% expected to care for an elderly person in the next 5 years. Only 5% strongly agreed that their division or department was concerned about supporting members' work-family balance, and 4% strongly agreed that existing programs supported their needs. Eighty-three percent reported feeling stressed as a result of efforts to balance work and family. Independent predictors of stress included perceived need to choose between career and family, increasing age, dependent children, less support from colleagues and supervisors, and female gender. CONCLUSIONS: Work-family balance issues are responsible for substantial perceived stress. Academic departments should consider a commitment to supporting faculty who are struggling with these issues, including creation of work-family policies and programs, development of mentoring systems, and reexamination of existing expectations for work practices.

Pediatric hospitalists in Canada and the United States: a survey of pediatric academic department chairs.

OBJECTIVES: To document the prevalence and practice patterns of pediatric hospitalists in academic centers in Canada and the United States; to characterize academic pediatric department chairs' definition of the term hospitalist; and to characterize pediatric department chairs' views of the training requirements for pediatric hospitalists. METHODS: A 14-item questionnaire was sent to all 145 pediatric department chairs from Canada and the United States during the fall of 1998. We defined hospitalists as physicians spending at least 25% of their time in inpatient care. RESULTS: Of the 145 eligible pediatric chairs, 128 (89%) responded (United States, 111/126; Canada, 14/16; Puerto Rico, 3/3). Ninety-nine (77%) of 128 pediatric chairs either have (64/128) or are planning to have (35/128) hospitalists in their institutions. Within academic programs with hospitalists, 82% of hospitalists currently work on general pediatric wards. Two thirds of hospitalists teach, 50% provide outpatient care, 50% have administrative duties, and 44% conduct research. One hundred eight (84%) of 128 believe that hospitalists should spend at least 50% of their time in inpatient care. Less than one third (30%) of pediatric chairs believe that hospitalists require training not currently provided in residency. CONCLUSIONS: A large proportion of academic pediatric centers either employed or planned to employ hospitalists in 1998. Pediatric academic department chairs do not see a need for training beyond residency for hospitalists. Further studies should address how pediatric hospitalists affect quality of care, cost, and patient satisfaction.

The challenges of automating a real-time clinical practice guideline.

OBJECTIVE: To elucidate the types of problems encountered during implementation of a World Wide Web-based clinical practice guideline to manage hyperbilirubinemia in newborn infants. DESIGN: Formative assessment of an automated clinical-practice guideline in a large-scale implementation. SETTING: Primary-care clinics and offices, inpatient clinics, and emergency department affiliated with an academic children's hospital. PARTICIPANTS: General pediatricians, neonatologists, pediatric nurses, and computer scientists. RESULTS: Existing guidelines for hyperbilirubinemia management could not be translated directly into web pages. Modifications of the original guidelines were required to represent the clinical intent of the guidelines accurately. In addition, the automated guideline was augmented to incorporate a mechanism for generating clinical encounter forms in order for the system to be accepted into the clinical work flow. Other clinical considerations that influenced the final form of the automated guideline included limitations of computer resources and time constraints during patient encounters. CONCLUSIONS: Many existing guidelines are not amenable to straightforward implementation in automated systems. Strategies to increase the efficacy of the automated guidelines included guideline modifications, as well as careful consideration of the flow of clinical work. Repeated cycles of development and pilot testing are needed to design methods to accommodate the constraints imposed by clinical use.

Managed care and the quality of children's health services.

Managed care has changed the practice of medicine. The choice of health care providers has been narrowed, physicians are being held financially accountable for the number of services they use, and a new emphasis is being placed on the cost and quality of the care provided. The transition to managed care has occurred with little attention to its impact on access to health care services or the quality of services provided. There is an absence of information about how children fare in these new systems. What little is known indicates that children in managed care arrangements are less likely to be able to be seen by pediatric specialists, and that families and providers are less satisfied under managed care. The impact of these changes on children's health status, however, is yet to be determined. For children with special needs, the problems of coordination of care, coverage of needed services, and the choice of the appropriate pediatric subspecialists, many of which existed in traditional fee-for-service systems, persist under managed care. In spite of all of the negative anecdotes about managed health care, managed care's focus on its population of enrollees and its heightened sense of a need for health care accountability bring exciting new opportunities to measure and improve the health care children receive. A new emphasis is being placed on practicing evidence-based medicine; the focus is on closing the gap between what is known (effective, evidence-based care) and what is done (current practice). Improved health outcomes and reduced health care costs have been documented in demonstration projects in neonatal intensive care units and in pediatric offices. Applying the principles of these learning collaboratives and employing the tools of continuous quality improvement in health care are urgent challenges that deserve to be met. Health plans, physicians, health care purchasers, regulators, families, and their children must work together to assure that children receive the highest-quality care possible--care that is technically excellent and medically appropriate, and that improves the health of our children.
