The gap in injury mortality rates between urban and rural residents of Hubei province, China

<p>Abstract</p> <p>Background</p> <p>Injury is a growing public health concern in China. Injury death rates are often higher in rural areas than in urban areas in general. The objective of this study is to compare the injury mortality rates in urban and rural residents in Hubei Province in central China by age, sex and mechanism of injury.</p> <p>Methods</p> <p>Using data from the Disease Surveillance Points (DSP) system maintained by the Hubei Province Centers for Disease Control and Prevention (CDC) from 2006 to 2008, injury deaths were classified according to the International Classification of Disease-10^thRevision (ICD-10). Crude and age-adjusted annual mortality rates were calculated for rural and urban residents of Hubei Province.</p> <p>Results</p> <p>The crude and age-adjusted injury death rates were significantly higher for rural residents than for urban residents (crude rate ratio 1.9, 95% confidence interval 1.8-2.0; adjusted rate ratio 2.4, 95% confidence interval 2.3-2.4). The age-adjusted injury death rate for males was 81.6/100,000 in rural areas compared with 37.0/100 000 in urban areas; for females, the respective rates were 57.9/100,000 and 22.4/100 000. Death rates for suicide (32.4 per 100 000 vs 3.9 per 100 000), traffic-related injuries (15.8 per 100 000 vs 9.5 per 100 000), drowning (6.9 per 100 000 vs 2.3 per 100 000) and crushing injuries (2.0 per 100 000 vs 0.7 per 100 000) were significantly higher in rural areas. Overall injury death rates were much higher in persons over 65 years, with significantly higher rates in rural residents compared with urban residents for suicide (279.8 per 100 000 vs 10.7 per 100 000), traffic-related injuries, and drownings in this age group. Death rates for falls, poisoning, and suffocation were similar in the two geographic groups.</p> <p>Conclusions</p> <p>Rates of suicide, traffic-related injury deaths and drownings are demonstrably higher in rural compared with urban locations and should be targeted for injury prevention activity. There is a need for injury prevention policies targeted at elderly residents, especially with regard to suicide prevention in rural areas in Central China.</p

Economic Profiling of Primary Care Physicians: Consistency among Risk-Adjusted Measures

OBJECTIVE: To investigate whether different risk-adjustment methodologies and economic profiling or “practice efficiency” metrics produce differences in practice efficiency rankings for a set of primary care physicians (PCPs). DATA SOURCE: Twelve months of claims records (inpatient, outpatient, professional, and pharmacy) for an independent practice association HMO. STUDY DESIGN: Patient risk scores obtained with six profiling risk-adjustment methodologies were used in conjunction with claims cost tabulations to measure practice efficiency of all primary care physicians who managed 25 or more members of an HMO. DATA COLLECTION: For each of the risk-adjustment methodologies, two measures of “efficiency” were constructed: the standardized cost difference between total observed (standardized actual) and total expected costs for patients managed by each PCP, and the ratio of the PCP's total observed to total expected costs (O/E ratio). Primary care physicians were ranked from most to least efficient according to each risk-adjusted measure, and level of agreement among measures was tested using weighted kappa. Separate rankings were constructed for pediatricians and for other primary care physicians. FINDINGS: Moderate to high levels of agreement were observed among the six risk-adjusted measures of practice efficiency. Agreement was greater among pediatrician rankings than among adult primary care physician rankings, and, with the standardized difference measure, greater for identifying the least efficient than the most efficient physicians. The O/E ratio was shown to be a biased measure of physician practice efficiency, disproportionately targeting smaller sized panels as outliers. CONCLUSIONS: Although we observed moderate consistency among different risk-adjusted PCP rankings, consistency of measures does not prove that practice efficiency rankings are valid, and health plans should be careful in how they use practice efficiency information. Indicators of practice efficiency should be based on the standardized cost difference, which controls for number of patients in a panel, instead of O/E ratio, which does not

Managed Care, Medical Technology, and Health Care Cost Growth: A Review of the Evidence

Although managed care plans reduce health care expenditures at any point in time, less is known about whether such plans control health care cost growth. Because use of new medical technology is an important determinant of cost growth, the impact of managed care on utilization of medical technology will largely determine whether managed care can reduce expenditure growth to sustainable levels. This article reviews the literature relating medical technology to cost growth and the literature examining the impact of managed care on either cost growth or on the diffusion of medical technology. Studies that examine plan-level data often reach different conclusions than studies that examine market-level data. The evidence suggests that managed care, as currently practiced, may reduce the rate of cost growth. However, managed care is unlikely to prevent the share of gross domestic product spent on health care from rising unless the cost-increasing nature of new technology changes.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68674/2/10.1177_107755879805500301.pd
