痛

黑暗!黑暗!!黑暗!!!这样的世界看不到半点光明。孤独的舞者终究还是孤独地倒下,然后又孤独地消失。黑暗呀,为什么老是缠绕着我?一声“妈妈”划破了天际,却也突不出黑暗的包围。谁来应我一声呀,妈妈,你在哪里呀?我的心在不停地挣扎,告诉自己:“不怕,不怕。”可这是在黑暗里呀,周     

Private cost containment. The effects of utilization review programs on health care use and expenditures

Utilization review has been regarded as one of the most promising approaches to the containment of health care costs. We analyzed insurance claims data on 222 groups of employees and dependents for 1984 and 1985 to evaluate the effects of utilization review programs instituted by a large private insurance carrier. The utilization review programs we studied were compulsory; patients who did not follow established utilization review procedures were subject to financial penalties. Controlling for employee characteristics, health care market area factors, and benefit-plan features, we found that utilization review reduced admissions by 12.3 percent, inpatient days by 8.0 percent, hospital expenditures by 11.9 percent, and total medical expenditures by 8.3 percent. When only groups that had relatively high admission rates before adopting utilization review were analyzed, it was found that they had a 34 percent reduction in patient days and a 30 percent reduction in hospital expenditures. The savings-to-cost ratio of utilization review for groups overall was highly favorable--approximately 8 to 1. Private utilization review programs of the type we studied appear to be effective in reducing hospital use and decreasing medical expenditures. This study did not address the possible effects of such programs on the health status of patients.     

Temperament as a moderator of children's stressful experiences

Data on 158 children, six and nine years old, are analyzed for the relationship between stress and behavior. Undesirable life events and intense "hassles" were particularly correlated with behavioral symptoms. Statistically, temperament appears to moderate this influence but, lacking appreciable variance of symptoms in the models including these interaction effects, the more parsimonious main-effects concept may be more useful.     

Hospital community benefits other than charity care: implications for tax exemption and public policy

Recent policy initiatives attempt to link the tax treatment of nonprofit hospitals more closely with the provision of social benefits. A key issue in defining these benefits is the treatment of "community benefit" programs and services. While their costs are often unreimbursed, these programs differ from traditional charity care in terms of the populations whom they benefit and the motivation for their provision. Community benefit programs are typically targeted to the general population, rather than the poor or other underserved groups, and often serve a marketing function.     

Early stage nasopharyngeal carcinoma: radiotherapy dose and time factors in tumor control

OBJECTIVE: To evaluate radiotherapy dose and length of treatment in the control of early stage nasopharyngeal carcinoma (NPC) treated with a combination of external radiotherapy and brachytherapy, MATERIALS & METHODS: We reviewed the records of 133 patients with early stage nasopharyngeal carcinoma (stage I or II, AJC/UICC staging system) who received definitive radiotherapy in Chang Gung Memorial Hospital from 1979 to 1991. The median follow-up time was 7.1 years with a minimum of 2 years. All patients were treated with megavoltage external radiotherapy to the nasopharynx area (63-72 Gy) followed by high dose rate intracavitary brachytherapy (5-16.5 Gy in one to three fractions, spaced 1-2 weeks apart). The median total dose and time of irradiation was 75 Gy (69.8-81.4 Gy) and 11.6 weeks (7.8-20 weeks) respectively. Survival analysis was used to examine the effect of several variables on prognosis. RESULTS: The 5-year rates were 86.4% for local control, 84.7% for disease free survival, 88.5% for actuarial survival and 84.2% for overall survival. The treatment group (combination of time and dose of irradiation) was the most important prognostic factor according to Cox's proportional hazard model. Patients receiving radiation at a total dose of < or = 75 Gy completed in < 12 weeks showed the best prognosis. CONCLUSION: Treatment time and total treatment dose are both important factors in treating early stage NPC. Decreasing the total radiation time to < 12 weeks and not exceeding a radiation dose of 75 Gy gave the best results.      

Bronchoscopic management of airway obstruction in pediatric endobronchial tuberculosis

The present report describes a case of severe airway obstruction caused by endobronchial tuberculosis in an 11-year-old girl who was successfully treated by bronchoscopic balloon dilation. This case illustrates the insidious presentation and the increasingly important role of bronchoscopic intervention in the management of endobronchial tuberculosis. In addition, a brief literature review of the condition in the pediatric age group is included.
