Cost-effectiveness analysis of antiretroviral drug treatment and HIV-1 vaccination in Thailand.

The prevalence of adult HIV/AIDS in Thailand is declining due to intense prevention strategies, but it still continues to be a critical health problem with a prevalence of 1.5%. Several HIV vaccine candidates for the prevention of HIV infection or progress to AIDS were examined in clinical trials. We evaluated the cost-effectiveness of a vaccination regimen (rBCG prime-rDIs boost) currently in its pre-clinical phase. The cost-effectiveness of three interventions (vaccination, highly active antiretroviral treatment [HAART], and the combination of the two) through an existing vaccination program was assessed in a Markov model. The disability-adjusted life year (DALY) was the main effectiveness measure. In the base case the efficacy of the vaccine for preventing HIV infection was assumed to be 30%. The cost of the vaccine was estimated on the basis of its predicted production capacities in Thailand. The incremental cost-effectiveness ratios of vaccination, HAART, and the combination were about dollar US 75, dollar US 610, and dollar US 267 per DALY averted compared with the do-nothing strategy in the base case. The HAART-only strategy seemed to be less cost-effective than the other options under the current assumptions. Sensitivity analyses indicated that the new HIV infection rate and the vaccine efficacy could affect the results.

Hair analysis of nicotine and cotinine for evaluating tobacco smoke exposure by liquid chromatography-mass spectrometry.

A simple liquid chromatography-electrospray ionization mass spectrometry (LC-ESI-MS) method for the determination of nicotine and cotinine in human hair was established. In the procedure, a hair sample (10 mg) was washed with dichloromethane and digested in 2.5 M sodium hydroxide. The digest was extracted with dichloromethane and then 25 mM hydrochloric acid in methanol was added to the extract, to prevent loss of analytes. The solution was evaporated and redissolved in the mobile phase, methanol/10 mM ammonium acetate (30/70, v/v). A 20 microL aliquot of redissolved solution was subjected to analysis. Nicotine and cotinine in human hair were quantified by using deuterated analytes as internal standards. The quantification limits were 8 microg/L for nicotine and 0.9 microg/L for cotinine. The proposed method was applied to measure the concentrations of nicotine and cotinine in hair of smokers and non-smokers to evaluate their self-reported smoking and exposure to environmental tobacco smoke. In both cases, the method provided good selectivity, accuracy and precision.

[Objective evaluation of clinical pharmacy lectures and experience in a master program using visual analog scale method].

We conducted an investigation to determine whether the visual analogue scale (VAS) method could be utilized in evaluating the lectures and pharmacy experience of the Division of Pharmacy and Health Sciences, Graduate School of Natural Science and Technology, Kanazawa University. Graduate students who had finished the 1-year pharmacy experience at the Kanazawa University Hospital were asked to make a self-evaluation of the understanding/attainment of lectures and experience in the course. Since the experience was carried out as a one-student-to-one-pharmacist system, the preceptors (pharmacists) were also asked to evaluate their corresponding students. When evaluating the necessity of the lectures, students tended to feel that the medical science- or pharmacotherapy-related subjects were important and those of social sciences were less important. These results suggest the need to review the contents of the lectures to enhance the interests of the students in the latter. By comparing the extent of understanding of each lecture before and after pharmacy experience, it was found that students had a better understanding of the lectures through their experience. In most results from the answers in pharmacy experience, students also scored themselves higher than their preceptors. Therefore comparisons of evaluation may provide more objective results in pharmacy experience. It was demonstrated that utilization of the VAS method and comparing the data are very useful in evaluating not only students' understanding/attainment but also the importance and usefulness of lectures and pharmacy experience in an objective way.

[The effects of the revision of medical repayment standards on pharmaceutical counseling services and revenue at pediatrics of Kanazawa University Hospital].

This paper analyzes the effects of the revision of medical repayment standards in April 2000 on pharmaceutical care and economics. The total number of sessions of counseling that can be claimed in 1 month has apparently improved at the Pediatrics Department of Kanazawa University Hospital. On the other hand, actual repayment for said services has not necessarily risen accordingly. This was shown by adopting new calculation modalities for actual claims before revision. We believe that this discrepancy occurs because the charge for each service has decreased from 480 points to 350 points, while maximum number of effective claims per month has risen from twice to four times.
