Utilization of care in haemophilia: a resource-based method for cost analysis from the Haemophilia Utilization Group Study (HUGS)

Summary.  The Haemophilia Utilization Group Study (HUGS) was created 10 years ago to examine the annual utilization and cost of haemophilia-related healthcare services. Retrospective chart reviews for 336 patients with haemophilia A receiving treatment in one of five comprehensive haemophilia treatment centres (HTCs) during 1995 were completed through interview of the provider. This method provided adequate collection of data from patient charts without the abstractor having direct access to patient health information. Utilization data were used to impute the costs of different components of care (e.g. physician visits, factor VIII concentrate, emergency room, hospitalization). The total annual cost of care was $139 102 (SD $304 033). Factor VIII concentrate costs comprised the largest proportion of these costs; mean factor VIII concentrate use was 128 517 units per patient per year. Unbilled physician utilization accounted for 7.8% of the mean total physician costs per annum, while mean allied healthcare costs accounted for 33.5% of the total annual allied healthcare costs per patient. In the ordinary least-squares regression model, higher costs were associated with severe factor VIII deficiency, arthropathy, more comorbid conditions, an inhibitor to factor VIII concentrate, infusing through a port and prophylaxis. Although factor VIII concentrate is the most costly component, the treatment of haemophilia uses many healthcare resources. HUGS has demonstrated that patient clinical characteristics and physician practices predominantly drive the costs of haemophilia care. Specifically, patients with more severe arthropathy had greater healthcare costs. As future funding decisions are made, it is important to provide for all components of care.     

外伤性截瘫合并耳聋11例临床分析

初步分析了11例外伤性截瘫合并耳聋患者,指出外伤性截瘫多有慢性肾功能不全、肾性贫血等并发症。这些并发症对耳聋的发生有一定的影响,但长时间或反复使用耳毒性药物是一个不可忽视的重要因素。作者对此提出了预防耳聋的一些具体措施,可供临床参考或借鉴。     

中国18城市新生儿死因研究

我们于1988年5月～1989年4月对我国18城市19所医院住院分娩的60960例活产婴进行了前瞻性调查研究.60960例中死亡556例,总死亡率9.12‰,其中死亡率男高于女,早产、低体重儿高于过期产儿和足月、正常体重儿,三胎和双胎高于单胎.前6位死因依次为窒息(或羊水胎粪吸入)、呼吸系统疾病、感染、畸形、颅内出血和硬肿症.并对各种死因在不同孕周、体重以及不同日龄组中的分布特点及主要防治对策进行了分析讨论.     

孤立性左肝胆管结石并肝管狭窄的外科治疗

目的总结近２０年来孤立性左肝胆管结石并发左肝胆管狭窄的临床治疗体会．方法原发性肝胆管结石１０１８例，年龄２７～７２岁，其中孤立性左肝胆管结石１３３例，手术治疗１１２例，对其临床资料进行回顾性分析，包括各肝管狭窄并发率，术前各项检查确诊率，手术治疗方式，再狭窄率．结果左肝管狭窄的发生率为５９８％，左外肝管和左内肝管分别为８４０％和８４８％，均以重度狭窄为主．狭窄切开整形后高位胆肠吻合术是处理左肝管狭窄的常用手术方式（５２２％），远期再狭窄率为１７１％；左半肝切除术施实率为１９４％，再狭窄率为００％；狭窄整形术和狭窄扩张术的施实率分别为９０％和１９４％，再狭窄率分别为５００％和９２３％．左外肝管狭窄通常采用肝段或肝叶切除术（７８７％），而左内肝管狭窄的处理则通常采用非左半肝切除术（８４８％）．左内肝管狭窄的术前／后影像学确诊率明显低于左肝管和左外肝管，平均确诊率依次２５９％，９３３％和８７９％．结论二级肝管狭窄是孤立性左肝管结石的常见并发症，肝叶或肝段切除术是其首选治疗原则．过多依赖非肝叶／段切除术和不适当的肝段切除术是遗留狭窄和远期疗效差的重要原因     

医疗卫生服务价格改革方向初探

医疗卫生服务价格改革是要理顺价格构成成份之间量的关系，使每个构成成份的价格值都在供求关系的约束中，在政府的有效管制中，从而成为医疗卫生资源合理配置的有效工具。为此：①对生产要素分别定价；②对劳动定价；③对资本和自然资源定价；④确定医疗卫生机构内部管理时劳动价格；⑤价格中的所有构成成份价格都置于供给和需求关系约束下；⑥确定医疗卫生服务价格的理想传递方式。
