Abstract
AIMS To assess pharmacy claims and self-report data as measures of medication adherence and to describe baseline characteristics of subjects in the Improving Diabetes Outcomes Study. METHODS Multi-ethnic, lower-income, insured adults (n = 526) in New York City with Type 2 diabetes were enrolled in a randomized, controlled, behavioural intervention study delivered by telephone. Baseline data were examined, including glycated haemoglobin (HbA(1c)), objective measures of diabetes medication adherence [claims data medication possession ratio (MPR)], and two self-report measures [Morisky Medication-taking Scale and the medication-taking item of the Summary of Diabetes Self-Care Activities (SDSCA)]. Associations of highest tertile HbA(1c) (>or= 9.3%) with lowest tertile MPR (< 42%) were assessed with logistic regression models adjusting for potential confounders. Subset analyses were performed based on assessment of potential interaction. RESULTS Participants (mean +/- sd age 56 +/- 7 years) had median (interquartile range) HbA(1c) 8.6% (8.0-10.0). Correlations of baseline MPR with Morisky score and SDSCA medication-taking item were strongly significant (both rho = 0.21, P < 0.001). Lowest MPR was significantly (P = 0.008) associated with highest HbA(1c) in the group as a whole and among the subset taking two or more oral glucose-lowering agents (OGLA) (P = 0.002), but not among the subset taking only one (P = 0.83). Self-report adherence measures were not significantly associated with HbA(1c) in either the whole group or either subset. CONCLUSIONS These results support the validity of MPR as an adherence measure for OGLA among insured diabetes patients with poorly controlled HbA(1c), especially those taking two or more OGLA.

Abstract
BACKGROUND Cross-boundary working is a key policy objective. Cross-boundary working provides the foundation for high quality provision across child health services and is imperative for an effective child protection system and the support of children and young people with health needs. METHODS Two participative conferences were attended by 113 stakeholders utilizing the World Café focus group method. Most (87%) of the sample were nurses, midwives or health visitors. RESULTS Many examples of cross-boundary working were identified across the different areas of practice. Remarkably few transdisciplinary examples were identified in contrast to the number of inter-agency examples. Intra-organizational boundaries across the health service were also noted. CONCLUSIONS Considerable cross-boundary working was reported but transdisciplinary working is not yet well established across all areas of child health provision.

Abstract
BACKGROUND Effective transition to adult services is required by an increasing number of children with ongoing needs. AIM To identify practices that promote continuity at transition between child and adult services. METHODS Systematic examination of the evidence from two search strategies yielding 5319 items. RESULTS Only three of the 126 appraised items had strong external validity. A large range of different practices, which focused on the service, the young person and the family, were identified. Practices within the service addressed structural, process and outcome components. CONCLUSION Four transition models are proposed for testing.

Abstract
BACKGROUND Increasing supplies of dermatologists and family physicians have been associated with earlier detection of malignant melanoma. We investigated whether physician supply was similarly related to incidence and mortality rates of malignant melanoma. METHODS Using the state tumor registry, we determined melanoma incidence and mortality rates for the years 1993 to 1995 for each Florida county. We measured physician supply for each Florida county using data from the 1994 American Medical Association Physician Masterfile. Multiple linear regression analysis was used to determine relationships between physician supply and melanoma incidence and mortality rates, controlling for other county-level characteristics. RESULTS Among male patients, an increasing supply of family physicians was associated with higher melanoma incidence and lower melanoma mortality. Increasing supplies of dermatologists were associated with lower overall melanoma mortality rates, and increasing supplies of general internists were associated with higher overall melanoma mortality. CONCLUSION We found that melanoma incidence and mortality rates varied substantially among Florida's 67 counties, and that differences in physician supply explained some of this variability. Further study is needed to confirm these findings and to elucidate possible mechanisms that would account for these associations.

Abstract
Performance measurement has become increasingly popular in the health care delivery system of the United States. Until recently, the hospital was the most commonly scrutinized setting. With the expansion of managed care and the resulting compilation of large administrative databases, interest in performance measurement beyond the hospital setting has increased considerably. In particular, the performance of health maintenance organizations is now being assessed and reported publicly. The performance of individual physicians is also garnering considerable attention. This paper summarizes some of the many developments in performance measurement in managed care. The Health Plan Employer Data and Information Set (HEDIS) is described in the context of the national Report Card Pilot Project and with respect to local report card projects emerging around the United States. The lessons learned are identified, particularly with respect to external auditing of HEDIS data. Finally, the new initiatives of physician profiling and outcomes reporting are discussed.

Abstract
Community-wide surveys have demonstrated that managed care enrollees tend to express higher satisfaction with their health plan if they have been given the opportunity to make a choice between managed care and fee-for-service plans. This DataWatch shows similar results with plan-specific data, even for enrollees whose plan benefits include coverage for out-of-network services. That is, what matters seems to be choice at the time of enrollment, not at the point of service. Further, in the practical application of ranking plans on overall enrollee satisfaction, choice appears to be a more important influence than other factors that may receive attention, including enrollees' health status. We discuss this phenomenon with respect to competition and strategy in the managed care marketplace.

Abstract
This paper reports the effects on a community hospital's emergency room utilization that were brought about by the development of a primary care group practice. The practice, which has replaced the hospital's traditionally structured outpatient clinics, employs full-time, salaried physicians and provides evening office hours and 24-hour coverage. The primary care group appears to have effected a substantial reduction in pediatric emergency room use. To a lesser extent, utilization by former clinic users among the adult atients was also reduced. These reductions, however, created only modest impact in the context of the hospital's total emergency room use, owed in part to the relatively small size of the patient population who formerly had depended upon the hospital for primary care.

Abstract
The replacement of a community hospital's pediatric outpatient clinics with a physicians' group practice is described, and the effects of this development on the receipt of services by children of indigent families are analyzed. An expanded patient population, frequent telephone utilization, decreased emergency room use, and satisfactory parental perceptions are found. A comparative measure of effectiveness is obtained from a record review of the preventive care received by infants delivered by the hospital's staff obstetricians. The latter data show the group practice to be more successful than the clinics in initiating and maintaining well-child care in its facility, and in achieving the timed completion of immunizations and screening procedures. The experience indicates an acceptance by low-income families of an outpatient service that emphasizes the physician-patient relationship with limited use of outreach services and nonphysician providers. It also inidicates that such a system of care can be provided to a heterogeneous patient population within the same facility.

Abstract
Utilization of the emergency room at an urban community hospital is studied in a format designed to accomplish three complementary objectives: 1) to characterize a sample of individual patients, rather than an unweighted sample of visits, 2) to estimate the number of individuals served during a specified period and the magnitude of the relationship between these patients and the utilization of other hospital services, and 3) to introduce the patient's "frequency-of-visit" as an important variable in the analysis of emergency room utilization. Some specific findings are: 1) the vast majority of patients who used the emergency room did so very infrequently; 46,527 visits were made in one year by an estimated 34,286 different patients; 2) an estimated 2,586 patients made three or more visits during the year; a disproportionately large number of these "high-frequency" users were black, low-income, and from inner-city areas; a relatively small percentage of their visits were for accidental injury, 3) approximately 53 per cent of the hospital's inpatient admissions and 68 per cent of the inpatient days were generated by patients who also made at least one emergency room visit during the year studied.

Abstract
Contrary to the traditional role of the emergency room (ER) as a care source for the treatment of urgent medical needs, it is evident that substantial numbers of people now use the ER for the treatment of nonurgent problems. In this paper, we report on public opinion about the role of the ER, the accessibility of medical care, and factors that prompt the use of the ER rather than other sources of care. The data result from a community survey of households (N = 521) in the area of Rochester, New York, representative of a population of about 580,000 people. The findings, which relate ER utilization to source of payment, use of other sources of care, demographic variables, and consumer attitudes illustrate the rationality of the patient's use of ER facilities and reflect the patient's view of the ER as a place to obtain medical treatment when other sources are not available.
