Informal payment for health care and the theory of 'INXIT'   总被引:1,自引:0,他引:1  
Informal payments are known to be widespread in the post-communist health care systems of Central and Eastern Europe. However, their role and nature remains contentious, with the debate characterized by much polemic. This paper steps back from this debate to examine the theoretical basis for understanding the persistence of informal payments. The authors develop a cognitive behavioural model of informal payment, which draws on the theory of government failure and extends Hirschman's theory of 'exit, voice, loyalty', the behavioural responses to 'decline in firms, organizations and states'. It is argued that informal payment represents another possible behavioural reaction: 'inxit', which becomes important when the channels of exit and voice are blocked. The theory is applied to explain informal payments in Hungary, but can be shown to be relevant to other countries facing similar issues. The paper examines the proposed policies to tackle informal payments, and on the basis of the theory of 'inxit' it advocates that solutions should contain an appropriate balance between exit and voice to optimize the chances of maintaining a good standard of public services.  相似文献

BACKGROUND: Workers in informal small-scale industries (SSI) in developing countries involved in welding, spray painting, woodwork and metalwork are exposed to various hazards with consequent risk to health. Aim To assess occupational exposure and health problems in SSI in Dar es Salaam, Tanzania. METHODS: Focused group discussions (FGD) were conducted among SSI workers. Participants were assessed for exposure to occupational and environmental hazards, the use of protective equipment and health complaints by interview. The findings were discussed with participants and potential interventions identified. RESULTS: Three hundred and ten workers were interviewed (response rate 98%). There was a high level (>90%) of self-reported exposure to either dust, fumes, noise or sunlight in certain occupational groups. There was low reported use of personal protective equipment. There was a high level of self-reported occupational health problems, particularly amongst welders and metalworkers. Workers reported their needs as permanent workplaces, information on work related hazards, water and sanitation, and legislation for SSI. CONCLUSIONS: In SSI in Tanzania, our study suggests that workers have high levels of exposure to multiple health hazards and that use of protective equipment is poor. This group of workers warrants improved occupational health and safety provision.  相似文献

Growing evidence has demonstrated that informal fees for health services comprise a large proportion of total health spending in some countries. In 1999, individual out-of-pocket payments for health in Cambodia were estimated at 27 US dollars per person, with a proportion paid as under-the-table fees at public facilities. By formalizing such payments and implementing resource management systems within a comprehensive health financing scheme, Takeo Referral Hospital controlled out-of-pocket patient expenditures, ensured patients of fixed prices, protected patients from the unpredictability of hospital fees and promoted financial sustainability. Utilization levels increased by more than 50% for inpatient and surgical services, and cost recovery from user fees averaged 33%. Furthermore, the hospital phased out external donor support gradually over 4 years and achieved financial sustainability.  相似文献

Economic activity in Brazilian women has been increasing in recent years, particularly in the form of under- and self-employment, which allows more flexibility in the work schedule and facilitates part-time work, a crucial issue for women reconciling family duties and the need for a remunerated occupation. This paper investigates the gender difference in the association between employment status and common mental disorders (CMD). A cross-sectional survey of a random sample of private households included 683 adults aged 15 years and over living in Olinda, Brazil. The self-reporting questionnaire (SRQ-20) was used to estimate the prevalence of CMD. The association between unemployment and CMD for men (OR=1.77, 95% CI 0.8–3.9) was in the same direction as that found for women (OR=2.66, 95% CI 1.1–6.3), but not significant. In contrast to this, while women working in the informal sector were more likely to be a case of CMD than formal workers (OR=3.02, 95% CI 1.3–7.2), no difference was found for informally working men (OR=1.08, 95% CI 0.5–2.4). The estimated OR for female informal workers was out of the 95% confidence intervals of the corresponding OR estimated for males, and the test for interaction was statistically significant (p=0.04). From a policy perspective, the value of encouraging people to take informal work depends both on how quickly individuals can be moved out of unemployment into informal work compared to other destinations, and how well individuals fare once in informal work. The results of the present study suggest that working outside the protection of employment legislation and with limited opportunity for skill use may be a risk for women’s mental health.  相似文献

Although research has emerged documenting the psychosocial impact of family care for cancer patients, few efforts capture the multi-dimensional nature of cancer caregiving stress, particularly among socioeconomically diverse samples. Utilizing data collected from cancer caregivers at a non-urban, Southern US site and an inner-city, Northeastern US site (N=233), the present study identified predictors of multiple dimensions of caregivers' subjective stress (i.e. emotional appraisals of care demands). Various indicators representing the sociodemographic context of care, cancer care demands, and psychosocial resources were found to exacerbate or buffer caregivers from feelings of exhaustion, role entrapment, and loss of intimacy with the cancer patient. The multivariate regression model also emphasized the diffuse yet potent role care recipient mood problems and caregiver mastery/optimism have on multiple dimensions of subjective stress. The findings offer a number of recommendations for future research and practice focused on informal cancer care.  相似文献

This research considers the impact of having a religious faith on the cancer experience of patients and informal carers, focusing primarily on the association between faith and psychosocial needs. A questionnaire survey of 1000 patients in the north-west of England returned 402 completed questionnaires; around two-thirds of patients indicated they had an informal carer. Using logistic regression analysis, we examine the relationship between the importance of 48 needs and faith for 189 paired patients and carers, while controlling for the effect of eight socio-demographic and clinical variables. Patients with expressed faith identified fewer psychosocial needs than those without faith. In contrast, carers with expressed faith identified more needs than those without faith in relation to support from family and neighbours. Carers also needed more help with finding a sense of purpose and meaning, and help in dealing with unpredictability. Not surprisingly, both patients and carers with faith identified a greater need for opportunities for personal prayer, support from people of their own faith and support from a spiritual adviser. Various explanations of these differences between patients and carers are proposed. The crucial point is that one should not too readily assume that the cancer experience is shared in the same way by patients and carers. In understanding the faith dimension, one needs to consider both the spiritual and secular aspects of having a religious faith.  相似文献

Objective. To describe the last year of life of people with dementia, their symptoms, care needs, use of and satisfaction with health services and the bereavement state of the respondent. Methods. The study is drawn from the Regional Study of Care for the Dying, a retrospective sample survey of the carers, family members or others who knew about the last year of life of a random sample of people age 15 and over dying in the last quarter of 1990. The samples were drawn in 20 English health districts which, although self-selected, were nationally representative. There was a total of 3696 patients (response rate of 69%) dying from all causes. Within this sample, 170 dementia patients were identified and compared with 1513 cancer patients. Results. The symptoms most commonly reported in the last year were mental confusion (83%), urinary incontinence (72%), pain (64%), low mood (61%), constipation (59%) and loss of appetite (57%). Dementia patients saw their GP less often than cancer patients and their respondents rated GP assistance less highly. Dementia patients needed more help at home compared with cancer patients, and received more social services; 78% of respondents for dementia patients and 64% for cancer said they had come to terms with the patient's death. Conclusion. Patients dying from dementia have symptoms and health care needs comparable with cancer patients. Greater attention should be given to these needs. © 1997 by John Wiley & Sons, Ltd.  相似文献
