Measuring fnancial risk protection The measurement of financial risk protection should ideally capture the number of people enrolled in some kind of health insurance scheme and the number of people who are eligible to use – and able to afford – health services provided by government, private sector or civil society. Direct and indirect indicators of fnancial risk protection Direct indicators Explanation Incidence of catastrophic health The number of people or the proportion of the population at all income levels expenditure due to out-of-pocket who spend a disproportionate share of their incomes on out-of-pocket pay- payments ments each year. Financial catastrophe is defned as out-of-pocket expenditure exceeding 40% of household income net of subsistence needs.

The poverty line is crossed when daily income falls below a locally-defned threshold, typically around US$1–2 per day. For people who are living near the poverty threshold, even small payments push them below the threshold.

GDP, gross domestic product; US$, United States dollars. There are, however, some difficulties in determining who is actually financially protected and to what extent, as two examples will make clear. First, health insurance as such does not guarantee full financial risk protection. Many forms of insurance cover only a minimum set of services, so that those insured are still required to make out-of-pocket payments of different types, including informal cash payments (1).

RESULTS significant but minimal reductions in ED use (ES –0 buy cheap fml forte 5 ml on line.

Facilitated or pure self-care support did not significantly reduce ED visits (ES –0. The lack of data for total costs prohibited a meaningful analysis of this outcome. Subgroup analyses additionally explored the effects of different intervention targets, formats, delivery modes and settings. ESs and 95% CIs for each of these subgroup analyses are shown in Table 8; results are highlighted where effects were statistically significant. In interpreting this table it is important to remember that any variation in the ESs observed for different subgroups will, in part, reflect differences in the number of studies available and the precision of the pooled estimates. Minimal but statistically significant effects (ES of < 0. With regard to hospital admissions, few positive effects were observed. Statistically significant but minimal benefits occurred with group-based interventions and mixed delivery models (i. Both of these findings were based on limited data and must therefore be treated with caution. Internal validity Table 10 shows the effects of self-care support on the four core outcomes, for the whole sample and the subset of studies rated as being at low risk of bias on the basis of adequate allocation concealment. Studies rated as being at low risk of bias reported minimal benefits of self-care support on QoL and ED visits and no significant effects on hospital admissions or costs. The effects observed for the subset of studies rated as being at low risk of bias were analogous to the full data set, suggesting that our main analyses were robust. Small-study bias The funnel plots for QoL and health utilisation outcomes are presented in Figures 20–23. A funnel plot is based on the premise that precision in the estimation of an ES will increase as sample size increases. Bias is suggested by the emergence of a non-symmetrical plot. This result is most likely influenced by a single study on the bottom left-hand side of the funnel plot.

RESULTS Funnel plot with pseudo 95% confidence limits 0 0. The impact of variation in context may be greater when considering complex service-related interventions, which are designed to have an impact on individual behaviour, or when the focus is on utilisation outcomes, which may themselves reflect important differences in the context in which the study is run. To explore this issue, we calculated overall ESs for QoL, hospitalisation, ED visits and total costs by country, to assess whether or not the effect of self-care interventions on these outcomes varied markedly between UK and non-UK settings. The results are shown in Table 11; analyses appear robust. The effects of self-care support on QoL are non-significant in the UK context, a difference that most likely reflects the smaller number of studies available and differences in precision of the pooled effects. When analyses were limited to UK studies, self-care support continued to be associated with statistically significant reductions in ED visits; this result did not hold for studies conducted outside the UK. Direct comparison of the two is limited in the sense that many other factors may also differ between studies that are assigned to different groups on the basis of research origin.

RESULTS Intervention implementation The external validity of research studies can improve the sustainable adoption and implementation of effective, generalisable, evidence-based interventions. The RE-AIM framework65 identities five pieces of information that are necessary to translate research into action. Reach The reach of health behaviour interventions refers to the absolute number, proportion and representativeness of individuals who receive it. Generally, data on such issues are poorly reported in trials and often the data that are reported are not comparable between studies. We extracted data from trials on the proportion of eligible patients who did not take part, these data are presented in Appendix 10.

GBR12909 attenuates am- phetamine-induced striatal dopamine release as measured by continuous infusion PET scans. The fourth method in which neuroreceptor imaging can assist in drug development is the empirical evaluation of theories of disease, such as the DA hypothesis for schizo- phrenia. For example, Grace (1991) (121) proposed that schizophrenia is characterized by intrasynaptic concentra- tions of DA that are abnormally low in the basal tonic state and abnormally high in the simulated phasic state. This has been supported by numerous findings of elevated dopa GBR 12909 (mg/kg) 18 decarboxylase measurements using [ F]fluorodopa (122), FIGURE 34.

These methods have also been employed in animal models using [19F]nuclear magnetic resonance (NMR) chemical shift imaging to study the cerebral distri- bution of general anesthetics in vivo (132). MAGNETIC RESONANCE IMAGING Magnetic resonance imaging (MRI) provides surrogate markers for disease progression to facilitate drug develop- A ment. For example, T2-weighted cerebral MRI functions as a surrogate marker in early stages of demyelinating disease to predict disease progression and disability over the subse- quent 10 years (132a–132e). Another example of the use of MRI as a surrogate marker for drug development is in the diagnosis and treatment of subjects with AD. Atrophy of the hippocampal formation has been correlated with memory and cognitive impair- ments. Reductions in the volume of the hippocampus have been predictive for the individuals who later develop mem- ory impairments consistent with AD (133). Another marker of the vulnerability to develop AD is the measure of the B apolipoprotein E (APOE) genotype. These histograms contrast the release of DA after AD is increased for people with the gene (134). The APOE administration of amphetamine (AMP) in Papio anubis baboons gene is associated with loss of hippocampal volume (135).
