Using the stated preference method for the calculation of social discount rate

The aim of this paper is to build the stated preference method into the social discount rate methodology. The first part of the paper presents the results of a survey about stated time preferences through pair-choice decision situations for various topics and time horizons. It is assumed that stated time preferences differ from calculated time preferences and that the extent of stated rates depends on the time period, and on how much respondents are financially and emotionally involved in the transactions. A significant question remains: how can the gap between the calculation and the results of surveys be resolved, and how can the real time preferences of individuals be interpreted using a social time preference rate. The second part of the paper estimates the social time preference rate for Hungary using the results of the survey, while paying special attention to the pure time preference component. The results suggest that the current method of calculation of the pure time preference rate does not reflect the real attitudes of individuals towards future generations

Can biomedical and traditional health care providers work together? Zambian practitioners' experiences and attitudes towards collaboration in relation to STIs and HIV/AIDS care: a cross-sectional study

BACKGROUND: The World Health Organization's World health report 2006: Working together for health underscores the importance of human resources for health. The shortage of trained health professionals is among the main obstacles to strengthening low-income countries' health systems and to scaling up HIV/AIDS control efforts. Traditional health practitioners are increasingly depicted as key resources to HIV/AIDS prevention and care. An appropriate and effective response to the HIV/AIDS crisis requires reconsideration of the collaboration between traditional and biomedical health providers (THPs and BHPs). The aim of this paper is to explore biomedical and traditional health practitioners' experiences of and attitudes towards collaboration and to identify obstacles and potential opportunities for them to collaborate regarding care for patients with sexually transmitted infections (STIs) and HIV/AIDS. METHODS: We conducted a cross-sectional study in two Zambian urban sites, using structured questionnaires. We interviewed 152 biomedical health practitioners (BHPs) and 144 traditional health practitioners (THPs) who reported attending to patients with STIs and HIV/AIDS. RESULTS: The study showed a very low level of experience of collaboration, predominated by BHPs training THPs (mostly traditional birth attendants) on issues of safe delivery. Intersectoral contacts addressing STIs and HIV/AIDS care issues were less common. However, both groups of providers overwhelmingly acknowledged the potential role of THPs in the fight against HIV/AIDS. Obstacles to collaboration were identified at the policy level in terms of legislation and logistics. Lack of trust in THPs by individual BHPs was also found to inhibit collaboration. Nevertheless, as many as 40% of BHPs expressed an interest in working more closely with THPs. CONCLUSION: There is indication that practitioners from both sectors seem willing to strengthen collaboration with each other. However, there are missed opportunities. The lack of collaborative framework integrating maternal health with STIs and HIV/AIDS care is at odds with the needed comprehensive approach to HIV/AIDS control. Also, considering the current human resources crisis in Zambia, substantial policy commitment is called for to address the legislative obstacles and the stigma reported by THPs and to provide an adequate distribution of roles between all partners, including traditional health practitioners, in the struggle against HIV/AIDS

Efficacy of patient-delivered partner medication in the treatment of sexual partners in Uganda.

BACKGROUND: Patient-based partner referral (PBPR), which is the main method for treating sexual partners of patients with sexually transmitted diseases (STDs), has limited effectiveness. GOAL: The authors compared the efficacy of PBPR with patient-delivered partner medication (PDPM) among patients attending the Mulago STD clinic in Kampala, Uganda. STUDY DESIGN: A total of 383 patients (187 women, 196 men) with STDs were randomized to the PBPR or PDPM group. The proportion of sexual partners treated in either group was compared using the chi-square statistic by intention to treat for partners whose follow-up status was unknown. RESULTS: The two groups had similar background characteristics. Of the 237 partners elicited, 176 (74%) were reported treated in the PDPM group. In the PBPR group, in which 234 partners were elicited, 79 (34%) were referred to the treatment clinic. This difference was statistically significant (risk ratio [RR], 2.44; 95% CI, 1.95-3.07; P < 0.001). Furthermore, PDPM was more effective than PBPR for women and for casual partners for whom PBPR is considered difficult. For women, 86 of 103 partners in the PDPM group were reported treated, compared with 23 of 104 partners in the PBPR group (RR, 4.55; 95% CI, 2.92-7.08; P < 0.001). For casual partners, 18 of 51 (34%) were reported treated in the PDPM group, compared with only three of 45 partners (7%) who were referred in the PBPR group (RR, 1.43; 95% CI, 1.40-2.65; P < 0.01). CONCLUSION: Patient-delivered partner medication is more effective than patient-based partner referral in the treatment of sexual partners

Public health services use in a mountainous area, Vietnam: implications for health for policy.

AIMS: The aim of this study is to describe the use of public health services in different social and ethnic groups and to explore the implementation of user fee exemption in a mountainous area in Vietnam. METHODS: A cross-sectional household survey with a structured questionnaire and a four-week diary were used to collect information on illnesses, health seeking behaviour and socioeconomic factors. Three communes in a mountainous district in Northern Vietnam were selected and a random sample of 1,452 individuals in 300 households was drawn. RESULTS: Self-medication was most common (57%) while 30% used public health services when suffering from a health problem. Persons living far from health services attended public health services less frequently than the others (adjusted OR = 0.28; 95% CI 0.15-0.51). This was especially the case for ethnic minorities who were less likely to use public health services than the others were (adjusted OR = 0.47; 95% CI 0.25-0.87). Persons with mild conditions tended to use public health services less than those with more severe conditions (OR = 0.19; 95% CI 0.10-0.37). Health services use was similar among women and men, but the total expenditure per visit was higher for men. Almost no patients supposed to get free attendance had been exempted from user fees. CONCLUSIONS: It was found that there was a geographical inequity in use of public health services while there was relatively equal use of these services between social, gender, and ethnic groups. Long distance in combination with failure of the fee exemption may increase inequity in use of health services in remote and isolated areas. These observations contribute to the basis for implementation of the Vietnamese health policy, emphasizing efficiency and equity

Psycho-social determinants for sexual partner referral in Uganda: Quantitative results

The purpose of this study was to investigate the factors influencing sexual partner referral using the Attitude-Social influence self-Efficacy model as a guiding theoretical framework. The data was collected in an interview survey with 236 women and 190 men attending a sexually transmitted disease clinic in Kampala, Uganda. Intention, attitude, subjective norm, self-efficacy, and past behaviour in relation to partner referral as well as partner type were collected at time 1. At time 2 (1 month later), sexual partner referral was assessed. Intention, self-efficacy, and previous behaviour predicted partner referral for women whereas intention, partner type and previous behaviour predicted partner referral for men. For the women the strongest predictors for intention were self-efficacy followed by attitude and partner type. For the men the strongest predictor was attitude followed by partner type and self-efficacy. Social influence was a better predictor of intention for women than for men. An analysis of underlying cognitive beliefs discriminating those who referred and those who did not refer the sexual partner showed that attitudinal beliefs were the most important for men whereas self-efficacy beliefs were the most important for women. The targeting of the gender-based discriminatory beliefs in intervention may improve compliance with sexual partner referral.STDs Partner notification Uganda Attitude Social-influence Self-efficacy
