A hierarchical classification for avoidable morbidity in infants was developed based on a conceptual model for causes of morbidity. Experts rated the impact of risk factors and health services on diseases coded according to the International Classification of Diseases, 9th Revision, Classification Modification (ICD-9-CM). An etiologic framework was chosen for the classification because knowledge of etiology often suggests strategies for prevention. Causes of morbidity that cluster on the basis of similar risk factors might be avoided using similar strategies. ⋯ The usefulness of this classification for policy-oriented epidemiologic and health services research is grounded in the premise that prevention is the cardinal objective of child health policy. Cluster-specific hospitalization rates, ie, rates aggregated for all diagnoses falling in a cluster, might be used for allocating resources to interventions directed at environmental or health service determinants of morbidity. Widespread use of ICD-9-CM codes in hospital discharge and ambulatory databases suggests many potential applications for this classification of morbidity burden in population groups.

The authors examine 58,441 obstetric deliveries in New York State outside New York City to test for the existence of defensive medicine in obstetrics. ⋯ The results appear to confirm the existence of defensive medicine in obstetrics. Whether this is a desirable or undesirable effect remains ambiguous, but it is costly.

Randomized Controlled Trial Comparative Study Clinical Trial
Assessing inner-city patients' hospital experiences. A controlled trial of telephone interviews versus mailed surveys.
Obtaining accurate and representative patient-centered data may be difficult among poor, inner-city patients because of changing addresses, variable access to telephones, and a higher prevalence of illiteracy than in the populations in which many survey instruments were developed and tested. Assumptions about the usefulness of mailed surveys versus telephone interviews may not hold for the urban poor. Therefore, identifying the most efficient mode of survey administration in this population becomes an important methodological question. ⋯ In this survey of patients served by an urban teaching hospital, a strategy of telephone interviews with mail follow-up proved less expensive and yielded a higher response rate with more complete data than using a method where mailed surveys were followed by back-up telephone interviews. In addition, we believe that the improved response rate for telephone interviews compared with those reported in the literature for similar populations is the result of informing inpatients of the survey and obtaining telephone numbers and addresses in the hospital.

Comparative Study
Care-seeking patterns of inner-city families using an emergency room. A three-decade comparison.
Since World War II, the urban hospital emergency room has been a major source of medical care for inner-city poor families, many of whom receive Medicaid. Given the expensive and episodic nature of emergency room care, there has been renewed interest in enrolling Medicaid recipients into managed care plans to increase access to care and to reduce medical costs. Thus, the primary care physician, in many managed care plans, is expected to give prior approval for emergency room care in nonurgent situations. The goals of managed care may create tension between its requirements and historical patterns of inner-city families seeking care in an emergency room. In 1964, Alpert developed a typology that categorized inner-city families' patterns of seeking medical care in a pediatric emergency department (PED) by describing the relation between regular source of medical care and reliance on this source before the PED visit. In 1976, using the same typology, Alpert and Scherzer updated care-seeking patterns in Boston after the introduction of neighborhood health centers (NHCs) and Medicaid. In 1993, the typology is a method that can be used to assess the impact of managed care on PED utilization by inner-city families. This article compares the 1993 pattern of seeking PED care with that measured in 1964 and 1976. ⋯ Efforts to provide access to care through Medicaid, NHCs, and hospital-based primary care resulted in a greater percentage of families reporting a regular source of care; however, a majority of families continue to exhibit an uncoordinated pattern of seeking care. More families in 1993 did not contact their regular source before seeking care in the PED when compared with 1964 and 1976. For managed care plans to increase access and reduce costs, a shift in PED utilization patterns remains necessary. The primary care system must have the capacity to accommodate these changes and considerable patient education must occur if urgent care is to be provided outside the PED.

The authors determine whether assessments of effects of rural emergency medical service (EMS) system characteristics on trauma outcomes (using patient-level data) are significantly biased if the Injury Severity Score (ISS) is not available. ⋯ In rural settings, where a patient's ISS generally is not available, studies of rural EMS system characteristics and trauma outcomes may use RTS, patient age, and type of trauma to control for expected survival. The patient's ISS does not appear to be essential, at least for the rural area analyzed in this study.
