背景:对于公立和私立机构合作(PPM)诊断和治疗结核病的成本效益方面的了解尚不足。设计:从新的国家结核病防治规划(RNTCP)角度,评价印度坎纳地区私立机构实验室开展PPM项目的花费及成本-效益。我们估算了每聘用并维持一个服务提供者的花费,估算了在不同效率假设的情况下多发现1例病人的花费、以及多成功治疗1例病人的花费。有关这些干预措施的花费的数据来自于国家结核病控制规划的登记资料,治疗花费的估算基于国家结核病控制规划的病例管理方案。结果:本项目每年总的估算花费为8 712～11611美元,平均每聘用1个私立服务提供者的费用从22～54美元不等,私立机构多诊断1例肺结核病人的花费为14～18美元。多登记1个病人,最保守的估算需花费29～36美元。每成功治疗1例抗酸杆菌阳性的病人约花费47～51美元。提高报告率会改善成本效益。结论:与公立卫生机构的诊断费用相比,需要明确这项干预措施是否对不同实施级别的公共卫生系统在经济上具有吸引力;如需扩展PPM项目,需要明确补充资源的需求。

Objective The purpose of this study was to determine whether an intra partum as sessment of amniotic fluid identifies a pregnancy that is at risk for an adverse outcome. Study design Parturients who were admitted for delivery were assigned randomly to have the amniotic fluid assessed either by amniotic fluid index or b y the presence of a 2 ×1 pocket. Results The amniotic fluid index was obtained in 499 pregnancies, and the 2 ×1 technique was performed in 501. Oligohydramnio s was diagnosed in 25%of amniotic fluid index pregnancies versus 8%with the us e of the 2 ×1 pocket technique (P < .001). Both techniques failed to identify p atients who underwent an amnioinfusion for fetal distress (P=.864) or who experi enced variable (P=.208) or late decelerations (P=.210) that influenced delivery, fetal distress in labor (P=.220), caesarean delivery for fetal distress (P=.133 ), and admission to neonatal intensive care unit (P=.686). Conclusion Neither th e amniotic fluid index nor the 2 ×1 pocket technique that was undertaken as a f etal admission test identi fies a pregnancy that is at risk for an adverse outco me.

Objective: To investigate the effect of cataract extraction on the visual fiel ds of patients with open-angle glaucoma. Methods: Patients in a prospective coh ort study in a tertiary center underwent standard automated perimetry every 6 mo nths. We compared the mean results of the 2 examinations immediately before and 2 examinations immediately after phacoemulsifi-cation cataract extraction and i ntraocular lens implant (effect analysis) and the mean results of the first 2 an d last 2 examinations from 4 consecutive examinations obtained more than 1 year after the cataract surgery (control analysis). Results: Our sample contained 34 eyes of 26 patients (mean±SD age, 69.2±10.8 years). While the mean log-MAR be st-corrected visual acuity improved significantly by approximately 2 Snellen li nes after surgery (P<.001), the average change in mean deviation in both the eff ect and control analyses was less than 0.1 dB and not statistically significant (P=.85). There was a strong correlation between change in foveal sensitivity and change in mean deviation in the effect analysis but not in the control analysis (r=0.76 [P< .001] and r=0.30 [P=.08], respectively). There was no relations hip between change in visual acuity or initial mean deviation and change in mean dev iation in either analysis. Change in pointwise total deviation was not systemati cally related to the respective baseline value in either analysis; however, the variance of the distribution of change in total deviation was significantly high er in the effect analysis (P< .001). Conclusion: While there was an improvement in best-corrected visual acuity after cataract surgery, the changes in the visu al field as a group were negligible.
