Shifting the culture of continuing medical education: what needs to happen and why is it so difficult?

A revolution in health care is occurring as a result of changes in the practice of medicine and in society. These include changing demographics and the pattern of disease; new technologies; changes in health care delivery; increasing consumerism, patient empowerment, and autonomy; an emphasis on effectiveness and efficiency; and changing professional roles. The issues raised by these changes present challenges for the content and delivery of the whole continuum of medical education. The ways in which continuing medical education (CME) needs to respond to these challenges are outlined. The Informed Shared Decision Making (ISDM) Project at the University of British Columbia is used as a case study to illustrate some of the practical problems in providing CME that address these current trends in health care, is effective, and is attractive to physicians. Two particular problems are posed: how to respond to a demonstrated need when there is no perceived need on the part of physicians and how to enable change agents on the margins to develop allies and get ownership from stakeholders and opinion leaders on the inside. Two strategies for change are discussed: the substantive incorporation of CME into the continuum of medical education and the involvement of patients in the planning and delivery of CME. A final challenge is raised for the leaders of CME to define and agree what "shifting the culture of CME" means and to make a commitment of time and energy into making it happen.     

Are socio-economic inequalities in mortality decreasing in Trent Region,UK? An observational study, 1988-1998

BACKGROUND: There is substantial national interest in the widening gap in socio-economic inequalities. The aim of this study was to examine time trends in age-specific mortality in Trent Region comparing rates by socio-economic deprivation from 1988 to 1998. METHODS: Mortality rates from 1988 to 1998 were calculated for each of five deprivation categories (derived using 1991-based enumeration district level Townsend scores) for men and women aged 45-54, 55-64, 65-74 and 75-84 years. Rate ratios (95 per cent confidence intervals) were calculated for the years 1988-1990 and 1996-1998, comparing the most deprived with the least deprived categories. RESULTS: For men aged 45-54, the rate ratio for the most deprived relative to the least deprived category was 2.42 (2.2-2.67) in 1988-1990 and 2.4 (2.17-2.65) in 1996-1998. Amongst women the ratio fell from 2.14 (1.88-2.42) to 1.67 (1.47-1.88). For men aged 55-64, the rate ratio fell from 2.07 (1.95-2.19) to 1.79 (1.67-1.91). For women the fall was from 1.99 (1.84-2.14) to 1.59 (1.46-1.73). For those aged 65-74, the fall was from 1.65 (1.58-1.72) to 1.33 (1.28-1.39) for men and from 1.55 (1.47-1.63) to 1.37 (1.30-1.45) for women. For people aged 75-84, no clear convergence in rates was seen. CONCLUSION: There appear to be decreases in socio-economic inequalities in mortality between 1988 and 1998 in Trent Region. These trends run counter to those described in the majority of recent literature.     

Rising inequalities in income and health in China: Who is left behind?

In recent decades, China has experienced double-digit economic growth rates and rising inequality. This paper implements a new decomposition approach using the China Health and Nutrition Survey (1991–2006) to examine the extent to which changes in level and distribution of incomes and in income mobility are related to health disparities between rich and poor. We find that health disparities in China relate to rising income inequality and in particular to the adverse health and income experience of older (wo)men, but not to the growth rate of average incomes over the last decades. These findings suggest that replacement incomes and pensions at older ages may be one of the most important policy levers for reducing health disparities between rich and poor Chinese.     

Inequalities in mortality by education and socio-economic transition in Lithuania: equal opportunities?

AIM: The aim of this study was to examine the changes in mortality differentials by level of education during the period of socio-economic transition in Lithuania. METHODS: This analysis was based on routine mortality statistics and census data for 1989 and 2001 for the entire country. RESULTS: Despite a general improvement in the level of education in the Lithuanian population, some negative educational patterns were observed amongst its young members. Increasing inequalities in mortality by education have occurred due to a declining mortality rate in people with higher educational achievements and, conversely, an increasing mortality rate in people with a low level of education. Mortality inequalities by education amongst females exceeded those amongst males in 2001, particularly in middle-aged groups and due to external causes. The results of this survey predict an unfavourable forecast of increasing health inequalities in Lithuania in the near future. CONCLUSIONS: General policies for health promotion and disease prevention should be based on the realities faced by lower educated groups, rather than on experiences that are general for the total population or the class of society that has at least achieved an average education. Inequalities in health by the level of education should plateau as the society-at-large enters into a more stable stage of social and economic development.     

Do ethnic and socio-economic inequalities in mortality vary by region in New Zealand? An application of hierarchical Bayesian modelling

We hypothesised that ethnic and socio-economic inequality in mortality might vary by region in New Zealand. Linked 2001–2004 census-mortality data were stratified by region (District Health Boards or DHBs), sex, age and ethnic groups, and income quintiles. To accommodate data sparseness, and to achieve accurate estimates of DHB-specific mortality rates and rate ratios by ethnicity and income, we used hierarchical Bayesian methods. To aid presentation of results, we used posterior mortality rates from the models to calculate directly standardised rates and rate ratios, with credible intervals. Māori-European/Other mortality rate ratios were often similar across DHBs, but Waitemata and Canterbury DHBs (both predominantly urban areas with low Māori population) had significantly lower rate ratios. In contrast, Bay of Plenty and Waikato DHBs (heterogeneous by both ethnicity and socio-economic position) had significantly higher rate ratios. There was little variation in mortality inequalities by income across DHBs. Examining the underlying rates for ethnic and income groups separately, there were significant variations across DHBs, but these were often correlated such that the ethnic or income rate ratio was similar across DHBs. The application of hierarchical Bayesian allowed more definitive conclusions than routine empirical methods when comparing small populations such as social groups across regions. The range of hierarchical Bayesian estimates of Māori mortality and Māori:European rate ratios across regions was considerably narrower than empirical standardisation estimates.     

Deficiency and BPC: what changes in the lives of people assisted?

The aim of this article is to analyze the impact of well-being provoked in the life of the disabled people after the Cash Benefit to Disabled People (BPC). The BPC is a social assistance benefit consisting in an unconditional and monthly transference of the equivalent of a minimum wage, to poor people with deficiency and elders with more than 65 years. The methodology used was a case study with qualitative and quantitative techniques of data collection and analysis. BPC performed interviews guided by a semi-structuralized questionnaire with 30 people with deficiency. The results showed that: (1) BPC is an important mechanism of security of income in the consumption of basic goods of feeding, health treatments and expenses with housing of deficient and its families; (2) disabled people had related the concession of the benefit to the increase of social and financial independence in relation to their families, contributing to expand the idea of autonomy and citizenship; (3) it is an instrument capable of protecting the benefited ones and their families of the situation of social vulnerability result of the poverty, although the mothers of the deficient children leave the work market to take care of their children and do not receive any kind of social protection from the State.     

The Chilean infant mortality decline: improvement for whom? Socioeconomic and geographic inequalities in infant mortality, 1990–2005

OBJECTIVE: To measure socioeconomic inequalities and differential risk in infant mortality on national and regional levels in Chile from 1990 to 2005, and propose new policy targets. METHODS: The study analysed Chilean vital events registries from 1990 to 2005 for infant mortality by maternal education, head of household occupational status, cause, age and location of death. Annual infant mortality rates and relative risk were calculated by maternal education and head of household occupational status for each cause and age of death. Socioeconomic inequalities were then mapped to 29 regional health services. FINDINGS: Reductions in the national infant mortality rate were driven by reductions among highly educated mothers, while recent stagnation in the national rate is caused by high levels of infant mortality among uneducated mothers. These vulnerable households are particularly prone to infant mortality risk due to infectious disease and trauma. We also identify clustering of high socioeconomic inequalities in infant mortality throughout the poorer north, indigenous south and densely populated metropolitan centre of Santiago. Finally, we report large inequities in vital statistics coverage, with infant deaths among vulnerable households much more likely to be inadequately defined than in the remaining population. CONCLUSION: These results indicate that the socioeconomically disadvantaged in Chile are at a significantly higher risk for infant mortality by infectious diseases and trauma during the first month of life. Efforts to reduce national infant mortality in Chile and other countries must involve policies that target child survival for at-risk populations for specific diseases, ages and locations.     

Female resistance to hypoxia: does it explain the sex difference in mortality rates?

There is currently no accepted explanation in the medical literature for the lower female total mortality rate in infancy, childhood and adulthood. We review the pediatric mortality data provided by Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) and show that for causes of respiratory infant death that are apparently independent of gender (e.g., suffocation from inhalation of food or other object), there is a consistently one-third lower rate of mortality in the female than in the male. This one-third lower mortality for causes of death with a respiratory terminal event is hypothesized to be due to an X-linked dominant allele that occurs with frequency 1/3. It appears as if a second X chromosome provides the one-third extra probability of protection afforded for an XX female compared with an XY male. It is suggested that the allele's function is unmasked during transient periods of cerebral anoxia, requiring a mechanism for anaerobic oxidation to prevent the death of respiratory control neurons in the brain stem. Examples of the female one-third extra chance of resistance to hypoxia are given for causes of death in infancy, such as infant respiratory distress syndrome (IRDS) and sudden infant death syndrome (SIDS), and for causes of suffocation in childhood and asphyxiation in adulthood. DNA testing of the X chromosome of probands from causes of respiratory death, such as SIDS and IRDS, where there is a one-third lower female than male death rate, is a future direction that can verify the existence of the proposed allele.     

Socioeconomic factors, ethnicity and alcohol-related mortality in regions in Slovakia. What might a tree analysis add to our understanding?

Regional differences in alcohol-related mortality might reflect strong socioeconomic differences between regions. The present study examines the contribution of education, unemployment, income and minority proportion on regional differences in alcohol-related mortality for inhabitants aged 20-64 years. Linear regression analysis and a non-parametric regression tree analysis were used separately for males and females. The unemployment rate and low education appeared as important determinants of regional alcohol-related mortality, while the proportion of Roma and income were not significantly associated with alcohol-related mortality among males in Slovak districts. A district's unemployment rate was assumed to be the strongest predictor of the outcome measure.     

Practising what we preach? A practical approach to bringing research, policy and practice together in relation to children and health inequalities

This paper explores the need for better links between research and practice in relation to work with children and health inequalities. Despite continuing discussion about the need to improve dissemination of research activity in general, study of this area remains largely neglected. As a result, despite the rhetoric, the research and practice gap continues to exist. An attempt to remedy this was undertaken through the support of a user fellowship as part of the UK Economic and Social Research Council Health Variations Programme. The paper describes a number of activities that were undertaken during the fellowship, and discusses the implications of these for improving connections and minimizing the research and practice 'gap'. It argues that a need exists for researchers to develop innovative dissemination strategies and suggests that potential exists for an interactive model of dissemination. Such a model implies a more active role for users of research in the shaping of research agendas.     

Reduced death rates from cyclones in Bangladesh: what more needs to be done?

Tropical storms, such as cyclones, hurricanes and typhoons, present major threats to coastal communities. Around two million people worldwide have died and millions have been injured over the past two centuries as a result of tropical storms. Bangladesh is especially vulnerable to tropical cyclones, with around 718 000 deaths from them in the past 50 years. However, cyclone-related mortality in Bangladesh has declined by more than 100-fold over the past 40 years, from 500 000 deaths in 1970 to 4234 in 2007. The main factors responsible for these reduced fatalities and injuries are improved defensive measures, including early warning systems, cyclone shelters, evacuation plans, coastal embankments, reforestation schemes and increased awareness and communication. Although warning systems have been improved, evacuation before a cyclone remains a challenge, with major problems caused by illiteracy, lack of awareness and poor communication. Despite the potential risks of climate change and tropical storms, little empirical knowledge exists on how to develop effective strategies to reduce or mitigate the effects of cyclones. This paper summarizes the most recent data and outlines the strategy adopted in Bangladesh. It offers guidance on how similar strategies can be adopted by other countries vulnerable to tropical storms. Further research is needed to enable countries to limit the risks that cyclones present to public health.     

Alcohol-related policy measures in Ontario: who supports what and to what degree?

Using 1998 provincial survey data (n = 1,205), the authors examine responses to 7 items concerning public opinion on alcohol-related policy in Ontario. The purpose of the study is to get a sense of overall public opinion on certain topical policy-related measures and to see whether this opinion is predicted by demographic characteristics of respondents (sex, age and self-reported drinking pattern). Cross-tabulations of opinion items with demographic variables revealed strong majority support for the status quo with regard to number of liquor and beer stores, beer and liquor store hours, and prohibition of the sale of alcohol in corner stores. A somewhat less robust majority also supported the status quo for alcohol taxes and legal drinking age. Among the demographic groups, high-risk heavy drinkers stood out for their greater support of relaxation of controls and this finding was confirmed by means of logistic regression. The majority of all groups, except frequent bar-goers, liked the idea of warning labels on alcoholic beverage containers. The authors conclude that, according to these survey data, policy initiatives towards greater access to alcohol, such as extended liquor store hours and sale of alcohol in corner stores, are not mandated by the majority of the population of Ontario.     

Income, income inequality and health: what can we learn from aggregate data?

It has been suggested that, especially in countries with high per capita income, there is an independent effect of income distribution on the health of individuals. One source of evidence in support of this relative income hypothesis is the analysis of aggregate cross-section data on population health, per capita income and income inequality. We examine the empirical robustness of cross-section analyses by using a new data set to replicate and extend the methodology in a frequently cited paper. The estimated relationship between income inequality and population health is not significant in any of our estimated models. We also argue there are serious conceptual difficulties in using aggregate cross-sections as a means of testing hypotheses about the effect of income, and its distribution, on the health of individuals.
