Explaining regional variation in elective hip and knee arthroplasties in Finland 2010 - 2017-a register-based cohort study.

BACKGROUND: A persistent research finding in industrialised countries has been regional variation in medical practices including elective primary hip and knee arthroplasty. The aim of the study was to examine regional variations in elective total hip and knee arthroplasties over time, and the proportions of these variations which can be explained by individual level or area-level differences in need. METHODS: We obtained secondary data from the Care Register for Health Care to study elective primary hip and knee arthroplasties in total Finnish population aged 25 + years between 2010 and 2017. Two-level Poisson regression models - individuals and hospital regions - were used to study regional differences in the incidence of elective hip and knee arthroplasties in two time periods: 2010 - 2013 and 2014 - 2017. The impact of several individual level explanatory factors (age, socioeconomic position, comorbidities) and area-level factors (need and supply of operations) was measured with the proportional change in variance. Predictions of incidence were measured with incidence rate ratios. The relative differences in risk of the procedures in regions were described with median rate ratios. RESULTS: We found small and over time relatively stable regional variation in hip arthroplasties in Finland, while the variation was larger in knee arthroplasties and decreased during the study period. In 2010 - 2013 individual socioeconomic variables explained 10% of variation in hip and 4% in knee arthroplasties, an effect that did not emerge in 2014 - 2017. The area-level musculoskeletal disorder index reflecting the need for care explained a further 44% of the variation in hip arthroplasties in 2010 - 2013, but only 5% in 2014 - 2017 and respectively 22% and 25% in knee arthroplasties. However, our final models explained the regional differences only partially. CONCLUSIONS: Our results suggest that eligibility criteria in total hip and knee arthroplasty are increasingly consistent between Finnish hospital districts. Factors related to individual level and regional level need both had an important role in explaining regional variations. Further study is needed on the effect of health policy on equity in access to care in these operations.

Change in medical practice over time? A register based study of regional trends in hysterectomy in Finland in 2001-2018.

BACKGROUND: A persistent research finding in Finland and elsewhere has been variation in medical practices both between and within countries. Variation seems to exist especially if medical decision making involves discretion and the best treatment cannot be identified unambiguously. This is true for hysterectomy when performed for benign causes. The aim of the current study was to investigate regional trends in hysterectomy in Finland and the potential convergence of rates over time. METHODS: We used hospital discharge register data on hysterectomies performed, diagnoses, age, and region of residence to examine hospital discharges for women undergoing hysterectomy in 2001-2018 among total female population aged 25 years or older in Finland. We examined hysterectomy rates among biannual cohorts by indication, calculated age-standardised rates and used multilevel models to analyse potential convergence over time. RESULTS: Altogether 131,695 hysterectomies were performed in Finland 2001-2018. We found a decreasing trend, with the age-adjusted overall hysterectomy rate decreasing from 553/100,000 person years in 2001-2002 to 289/100,000 py in 2017-2018. Large but converging regional differences were found. The correlations between hospital district intercepts and slopes in time ranged from - 0.71 to - 0.97 (p < 0.001) suggesting diminishing variation. CONCLUSIONS: Our findings demonstrate that change in hysterectomy practices and more uniformity across regions are achievable goals. Regional variation still exists suggesting differences in medical practices.

Mortality related to ambulatory care sensitive hospitalisations in Finland.

Aims: Hospitalisations for ambulatory care sensitive conditions are used as an outcome indicator of access to and quality of primary care. Evidence on mortality related to these hospitalisations is scarce. This study analysed the effect of ambulatory care sensitive condition hospitalisations to subsequent mortality and time or geographical trends in the mortality indicating variations in ambulatory care sensitive conditions outcomes. Methods: This retrospective cohort study used individual-level data from national registers concerning ambulatory care sensitive condition hospitalisations. Crude and age-adjusted 365-day mortality rates for the first ambulatory care sensitive condition-related admission were calculated for vaccine-preventable, acute, and chronic ambulatory care sensitive conditions separately, and for three time periods stratified by gender. The mortality rates were also compared to mortality in the general Finnish population to assess the excess mortality related to ambulatory care sensitive condition hospitalisations. Results: The data comprised a total of 712,904 ambulatory care sensitive condition hospital admissions with the crude 365-day mortality rate of 14.2 per 100 person-years. Mortality for those hospitalised for vaccine-preventable conditions was approximately 10-fold compared to the general population and four-fold in chronic and acute conditions. Of the 10 most common ambulatory care sensitive conditions, bacterial pneumonia and influenza and congestive heart failure were associated with highest age-standardised mortality rates. Conclusions: Hospitalisations for ambulatory care sensitive conditions were shown to be associated with excess mortality in patients compared to the general population. Major differences in mortality were found between different types of ambulatory care sensitive condition admissions. There were also minor differences in mortality between hospital districts. These differences are important to consider when using preventable hospital admissions as an indicator of primary care performance.

Digital Divide in Perceived Benefits of Online Health Care and Social Welfare Services: National Cross-Sectional Survey Study.

BACKGROUND: The number of online services in health care is increasing rapidly in developed countries. Users are expected to take a more skilled and active role in taking care of their health and prevention of ill health. This induces risks that users (especially those who need the services the most) will drop out of digital services, resulting in a digital divide or exclusion. To ensure wide and equal use of online services, all users must experience them as beneficial. OBJECTIVE: This study aimed to examine associations of (1) demographics (age, gender, and degree of urbanization), (2) self-rated health, (3) socioeconomic position (education, experienced financial hardship, labor market position, and living alone), (4) social participation (voting, satisfaction with relationships, and keeping in touch with friends and family members), and (5) access, skills, and extent of use of information and communication technologies (ICT) with perceived benefits of online health care and social welfare services. Associations were examined separately for perceived health, economic, and collaboration benefits. METHODS: We used a large random sample representative of the Finnish population including 4495 (56.77% women) respondents aged between 20 and 97 years. Analyses of covariance were used to examine the associations of independent variables with perceived benefits. RESULTS: Access to online services, ICT skills, and extent of use were associated with all examined benefits of online services. ICT skills seemed to be the most important factor. Poor self-rated health was also consistently associated with lower levels of perceived benefits. Similarly, those who were keeping in touch with their friends and relatives at least once a week perceived online services more often beneficial in all the examined dimensions. Those who had experienced financial hardship perceived fewer health and economic benefits than others. Those who were satisfied with their relationships reported higher levels of health and collaboration benefits compared with their counterparts. Also age, education, and degree of urbanization had some statistically significant associations with benefits but they seemed to be at least partly explained by differences in access, skills, and extent of use of online services. CONCLUSIONS: According to our results, providing health care services online has the potential to reinforce existing social and health inequalities. Our findings suggest that access to online services, skills to use them, and extent of use play crucial roles in perceiving them as beneficial. Moreover, there is a risk of digital exclusion among those who are socioeconomically disadvantaged, in poor health, or socially isolated. In times when health and social services are increasingly offered online, this digital divide may predispose people with high needs for services to exclusion from them.

The effect of history of severe mental illness on mortality in colorectal cancer cases: a register-based cohort study.

BACKGROUND: While the link between mental illness and cancer survival is well established, few studies have focused on colorectal cancer. We examined outcomes of colorectal cancer among persons with a history of severe mental illness (SMI). MATERIAL AND METHODS: We identified patients with their first colorectal cancer diagnosis in 1990-2013 (n = 41,708) from the Finnish Cancer Registry, hospital admissions due to SMI preceding cancer diagnosis (n = 2382) from the Hospital Discharge Register and deaths from the Causes of Death statistics. Cox regression models were used to study the impact on SMI to mortality differences. RESULTS: We found excess colorectal cancer mortality among persons with a history of psychosis and with substance use disorder. When controlling for age, comorbidity, stage at presentation and treatment, excess mortality risk among men with a history of psychosis was 1.72 (1.46-2.04) and women 1.37 (1.20-1.57). Among men with substance use disorder, the excess risk was 1.22 (1.09-1.37). CONCLUSION: Understanding factors contributing to excess mortality among persons with a history of psychosis or substance use requires more detailed clinical studies and studies of care processes among these vulnerable patient groups. Collaboration between patients, mental health care and oncological teams is needed to improve outcomes of care.

Effect of stage, comorbidities and treatment on survival among cancer patients with or without mental illness.

BackgroundEarlier research suggests poorer outcome of cancer care among people with severe mental illness (SMI).AimsTo assess the effect of stage at presentation, comorbidities and treatment on differences in survival among cancer patients with and without a history of SMI in Finland.MethodThe total population with a first cancer diagnosis in 1990-2013 was drawn from the Finnish Cancer Registry. Hospital admissions because of SMI and deaths were obtained from administrative registers. We calculated Kaplan-Meier estimates and Cox regression models to examine survival differences.ResultsWe found excess mortality in people with a history of psychotic and substance use disorders. Cancer stage and comorbidity did not explain mortality differences. Controlling for cancer treatment decreased the differences. The mortality gap between patients with psychosis and cancer patients without SMI increased over time.ConclusionsIntegrated medical and psychiatric care is needed to improve outcomes of cancer care among patients with SMI.

Trends of relative and absolute socioeconomic equity in access to coronary revascularisations in 1995-2010 in Finland: a register study.

BACKGROUND: Resources for coronary revascularisations have increased substantially since the early 1990s in Finland. At the same time, ischaemic heart disease (IHD) mortality has decreased markedly. This study aims to examine how these changes have influenced trends in absolute and relative differences between socioeconomic groups in revascularisations and age group differences in them using IHD mortality as a proxy for need. METHODS: Hospital Discharge Register data on revascularisations among Finns aged 45-84 in 1995-2010 were individually linked to population registers to obtain socio-demographic data. We measured absolute and relative income group differences in revascularisation and IHD mortality with slope index of inequality (SII) and concentration index (C), and relative equity taking need for care into account with horizontal inequity index (HII). RESULTS: The supply of procedures doubled during the years. Socioeconomic distribution of revascularisations was in absolute and relative terms equal in 1995 (Men: SII = -12, C = -0.00; Women, SII = -30, C = -0.03), but differences favouring low-income groups emerged by 2010 (M: SII = -340, C = -0.08; W: SII = -195, C = -0.14). IHD mortality decreased markedly, but absolute and relative differences favouring the better-off existed throughout study years. Absolute differences decreased somewhat (M: SII = -760 in 1995, SII = -681 in 2010; W: SII = -318 in 1995, SII = -211 in 2010), but relative differences increased significantly (M: C = -0.14 in 1995, C = -0.26 in 2010; W: C = -0.15 in 1995, C = -0.25 in 2010). HII was greater than zero in each year indicating inequity favouring the better-off. HII increased from 0.15 to 0.18 among men and from 0.10 to 0.12 among women. We found significant and increasing age group differences in HII. CONCLUSIONS: Despite large increase in supply of revascularisations and decrease in IHD mortality, there is still marked socioeconomic inequity in revascularisations in Finland. However, since changes in absolute distributions of both supply and need for coronary care have favoured low-income groups, absolute inequity can be claimed to have decreased although it cannot be quantified numerically.

Comparative observational study of mortality amenable by health policy and care between rural and urban Finland: no excess segregation of mortality in the capital despite its increasing residential differentiation.

BACKGROUND: Large cities are often claimed to display more distinct geographical and socioeconomic health inequalities than other areas due to increasing residential differentiation. Our aim was to assess whether geographical inequalities in mortality within the capital (City of Helsinki) both exceeded that in other types of geographical areas in Finland, and whether those differences were dependent on socioeconomic inequalities. METHODS: We analysed the inequality of distribution separately for overall, ischemic heart disease and alcohol-related mortality, and mortality amenable (AM) to health care interventions in 1992-2008 in three types of geographical areas in Finland: City of Helsinki, other large cities, and small towns and rural areas. Mortality data were acquired as secondary data from the Causes of Death statistics from Statistics Finland. The assessment of changing geographical differences over time, that is geographical inequalities, was performed using Gini coefficients. As some of these differences might arise from socioeconomic factors, we assessed socioeconomic differences with concentration indices in parallel to an analysis of geographical differences. To conclude the analysis, we compared the changes over time of these inequalities between the three geographical areas. RESULTS: While mortality rates mainly decreased, alcohol-related mortality in the lowest income quintile increased. Statistically significant differences over time were found in all mortality groups, varying between geographical areas. Socioeconomic differences existed in all mortality groups and geographical areas. In the study period, geographical differences in mortality remained relatively stable but income differences increased substantially. For instance, the values of concentration indices for AM changed by 54 % in men (p < 0.027) and by 62 % in women (p < 0.016). Only slight differences existed in the time trends of Gini or in the concentration indices between the geographical areas. CONCLUSIONS: No geographical or income-related differences in the distribution of mortality existed between Helsinki and other urban or rural areas of Finland. This suggests that the effect of increasing residential differentiation in the capital may have been mitigated by the policies of positive discrimination and social mixing. One of the main reasons for the increase in health inequalities was growth of alcohol-related mortality, especially among those with the lowest incomes.

Differences in mortality among women with breast cancer by income - a register-based study in Finland.

AIMS: The aim was to assess all-cause and breast cancer mortality by income among women with incident breast cancer and the effect of cancer stage at diagnosis and comorbidity on the differences. METHODS: The 43,439 women (age ⩾30) diagnosed with breast cancer in 1998-2008 in Finland were monitored using individual-level Cancer Registry data supplemented with data from Finnish health care registers and sociodemographic data. RESULTS: Overall mortality was greater among breast cancer patients of the lowest income group than in the highest one; the hazard ratio (HR) for age and incidence year adjusted all-cause mortality was 1.9 (95% CI 1.8-2.1) and for breast cancer mortality 2.0 (95% CI 1.8-2.2). The women from the lowest income group were over-represented in the breast cancer stage 'distant' (10.1% vs. 3.5% among the highest income group). The presence of comorbidities was more common in patients with the lowest income (at least one comorbidity in 54%) than in the highest (24%). The HR adjusted with stage at presentation and comorbidities was 1.6 (95% CI 1.4-1.7) for all-cause mortality and 1.6 (95% CI 1.4-1.7) for breast cancer mortality. CONCLUSIONS: Tumour stage at diagnosis was more severe among lower income groups, and the presence of comorbidities was more common, although this only accounted for a part of the higher breast cancer mortality in these groups. More information is needed about recognition, diagnosis and treatment of breast cancer to examine whether the socioeconomic differences of breast cancer mortality are related to care.

National and regional trends in equity within specialised health care in Finland in 2002-2010.

AIMS: Equity is an important goal of health-care systems. Nevertheless, previous research indicates that health-care systems do not deliver health services equitably and that socio-economic differences in both health and health-care use may even be increasing. The aim of this study was to investigate national and regional time trends in equity within specialised health care in Finland. METHODS: The data used in the study were obtained from the Hospital Discharge Register covering all hospital admissions in Finland from 2002 to 2010 for patients having utilised specialised non-psychiatric inpatient care. Income data were individually linked to these register data. Equity was measured in terms of concentration index at hospital district level. RESULTS: Concentration indices across hospital districts and years were negative, suggesting specialised inpatient care to be distributed pro poor. Overall, the concentration indices remained fairly stable during the study period. However, a drop in the indices appeared in all hospital districts between 2005 and 2008, and a reverse development was found after 2008. In internal medicine departments of the hospital districts, the distribution of the indices was more pro poor compared to surgery but the trends within both specialties were similar to those within specialised care in general. CONCLUSIONS: The pro-poor distribution of concentration indices is consistent with morbidity differences the introduction of the waiting time guarantee in 2005, which brought along an increment in resources, as well as the launch of new regulations and financial incentives, probably increased access to specialised health care among low-income patients temporarily.

Are there socioeconomic differences in outcomes of coronary revascularizations--a register-based cohort study.

BACKGROUND: Earlier studies have reported socioeconomic differences in coronary heart disease incidence and mortality and in coronary treatment, but less is known about outcomes of care. We examined trends in income group differences in outcomes of coronary revascularizations among Finnish residents in 1998-2010. METHODS: First revascularizations for 45-84-year-old Finns were extracted from the Hospital Discharge Register in 1998-2009 and followed until 31 December 2010. Income was individually linked to them and adjusted for family size. We examined the risk of major adverse cardiac events (MACEs), coronary mortality and re-revascularization. We calculated age-standardized rates with direct method and Cox regression models. RESULTS: Altogether 69 076 men and 27 498 women underwent revascularization during the study period. Among men [women] in the 1998 cohort, 41% [35%] suffered MACE during 29 days after the operation and 30% [28%] in the 2009 cohort. Myocardial infarction mortality within 1 year was 2% among both genders in both cohorts. Among men [women] 9% [14%] underwent revascularization within 1 year after the operation in 1998 and 12% [12%] in 2009. Controlling for age, co-morbidities, year, previous infarction and disease severity, an inverse income gradient was found in MACE incidence within 29 days and in coronary mortality. The excess MACE risk was 1.39 and excess mortality risk over 1.70 among both genders in the lowest income quintile. All income group differences remained stable from 1998 to 2010. CONCLUSIONS: In health care, more attention should be paid to prevention of adverse outcomes among persons with low socioeconomic position undergoing revascularization.

Multiple social disadvantage does it have an effect on amenable mortality: a brief report.

INTRODUCTION: Most studies on inequalities in health and health-care focus on single indicators of social position, e.g. income or education. Recent research has suggested that multiple social circumstances need to be analysed simultaneously to disentangle their influence on health. In past decades mortality amenable to health-care, i.e. premature mortality that should not occur given timely and effective health-care, has increasingly been used to study the effect of health-care on health outcomes. This study elaborates the effect of social and regional deprivation and unemployment on the association between income and mortality amenable to health-care in Finland. METHODS: Individual-level data for deaths were gathered by disease category between 1992 and 2008 for the resident Finnish population aged 25 to 59 years. Differences in amenable mortality and changes over time were assessed using individual-level linked register data. We used gender- and age-standardised rates and Poisson regression models to examine the simultaneous effect of these indicators on amenable mortality. RESULTS: Altogether 22,663 persons aged 25-59 years died from causes amenable to health-care during the study period. An inverse pattern was found in amenable mortality for income. The mortality rate in the lowest income quintile was 98 (93-104) per 100,000 in the period 1991-1996 while in the highest group the figure was 40 (38-42) for the same period. Whereas the level of amenable mortality decreased, mortality differences between income groups steepened and amenable mortality increased in the lowest income group towards the end of the study period. Those in poor labour market position or living alone had significantly larger income differences in amenable mortality. Risk of regional deprivation was not associated with amenable mortality. CONCLUSIONS: In order to prevent and treat at an early phase conditions that otherwise may lead to premature and unnecessary deaths more attention should be focused on groups with increased social and economic deprivation risk in municipal health centres with the aim at improving access to primary care. Our results also call for joint action by both health-care and social services, since health services alone cannot deal with the risks posed by accumulating social disadvantage.

Inflows of foreign-born physicians and their access to employment and work experiences in health care in Finland: qualitative and quantitative study.

BACKGROUND: In many developed countries, including Finland, health care authorities customarily consider the international mobility of physicians as a means for addressing the shortage of general practitioners (GPs). This study i) examined, based on register information, the numbers of foreign-born physicians migrating to Finland and their employment sector, ii) examined, based on qualitative interviews, the foreign-born GPs' experiences of accessing employment and work in primary care in Finland, and iii) compared experiences based on a survey of the psychosocial work environment among foreign-born physicians working in different health sectors (primary care, hospitals and private sectors). METHODS: Three different data sets were used: registers, theme interviews among foreign-born GPs (n = 12), and a survey for all (n = 1,292; response rate 42%) foreign-born physicians living in Finland. Methods used in the analyses were qualitative content analysis, analysis of covariance, and logistic regression analysis. RESULTS: The number of foreign-born physicians has increased dramatically in Finland since the year 2000. In 2000, a total of 980 foreign-born physicians held a Finnish licence and lived in Finland, accounting for less than 4% of the total number of practising physicians. In 2009, their proportion of all physicians was 8%, and a total of 1,750 foreign-born practising physicians held a Finnish licence and lived in Finland. Non-EU/EEA physicians experienced the difficult licensing process as the main obstacle to accessing work as a physician. Most licensed foreign-born physicians worked in specialist care. Half of the foreign-born GPs could be classified as having an 'active' job profile (high job demands and high levels of job control combined) according to Karasek's demand-control model. In qualitative interviews, work in the Finnish primary health centres was described as multifaceted and challenging, but also stressful. CONCLUSIONS: Primary care may not be able in the long run to attract a sufficient number of foreign-born GPs to alleviate Finland's GP shortage, although speeding up the licensing process may bring in more foreign-born physicians to work, at least temporarily, in primary care. For physicians to be retained as active GPs there needs to be improvement in the psychosocial work environment within primary care.

Has socioeconomic equity increased in somatic specialist care: a register-based cohort study from Finland in 1995-2010.

BACKGROUND: Equal access to health care according to need is an important goal for health policy in Finland. Earlier research in Finland and elsewhere has mainly been cross-sectional, but the results have implied that the goal has not been fully realised in somatic specialist hospital care. This study examines trends in socioeconomic equity in use of somatic specialist hospital care. METHODS: We used register data on somatic specialist hospital admissions among 25-84 year-old persons in Finland in 1995-2010 with individually linked register-based socio-demographic information. We calculated age-standardised admission rates per 100,000 person years by income, examined risk ratios using Poisson regression models and computed concentration indices separately for men and women. Linear trends in the socioeconomic distribution of admissions and surgical procedures were estimated with linear regression models for annual concentration indices. RESULTS: Overall, use of somatic specialist hospital care decreased steadily throughout the study period. A stepwise inverse income pattern was found in hospitalisation risk and in non-surgical admissions: the lower the income group, the higher the risk. The relative admission risk was approximately two times higher in the lowest income group compared to the highest among both genders. Few differences were found in surgical admissions. Income group differences remained stable in hospitalisations and surgical admissions, but increased in non-surgical admissions during the study period. An inverse pattern of increasing operation rates with decreasing income was found in primary hip and knee replacement operations, and in lower limb amputations. A similar pattern emerged during the study period in coronary revascularisations. There were no differences were found in lumbar fusion or lumbar disc operations, prostatectomies or appendectomies. Income group differences in hysterectomies disappeared during the study period. CONCLUSIONS: While the results of the current study suggest that use of somatic specialist care declined in line with improving population health in 1995-2010, the increase of socioeconomic health differentials was only partly reflected in the distribution of somatic specialist hospital care. Further research is needed to evaluate the need to improve use and content of specialised hospital care among the low-income groups in order to improve equity in health care.

The contribution of health policy and care to income differences in life expectancy--a register based cohort study.

BACKGROUND: Growing mortality differences between socioeconomic groups have been reported in both Finland and elsewhere. While health behaviours and other lifestyle factors are important in contributing to health differences, some researchers have suggested that some of the mortality differences attributable to lifestyle factors could be preventable by health policy measures and that health care may play a role. It has also been suggested that its role is increasing due to better results in disease prevention, improved diagnostic tools and treatment methods. This study aimed to assess the impact of mortality amenable to health policy and health care on increasing income disparities in life expectancy in 1996-2007 in Finland. METHODS: The study data were based on an 11% random sample of Finnish residents in 1988-2007 obtained from individually linked cause of death and population registries and an oversample of deaths. We examined differences in life expectancy at age 35 (e35) in Finland. We calculated e35 for periods 1996-97 and 2006-07 by income decile and gender. Differences in life expectancies and change in them between the richest and the poorest deciles were decomposed by cause of death group. RESULTS: Overall, the difference in e35 between the extreme income deciles was 11.6 years among men and 4.2 years among women in 2006-07. Together, mortality amenable to health policy and care and ischaemic heart disease mortality contributed up to two thirds to socioeconomic differences. Socioeconomic differences increased from 1996-97 by 3.4 years among men and 1.7 years among women. The main contributor to changes was mortality amenable through health policy measures, mainly alcohol related mortality, but also conditions amenable through health care, ischaemic heart disease among men and other diseases contributed to the increase of the differences. CONCLUSIONS: The results underline the importance of active health policy and health care measures in tackling socioeconomic health inequalities.

Socioeconomic differences in mortality amenable to health care among Finnish adults 1992-2003: 12 year follow up using individual level linked population register data.

BACKGROUND: Finland decentralised its universal healthcare system and introduced market reforms in the 1990s. Despite a commitment to equity, previous studies have identified persistent socio-economic inequities in healthcare, with patterns of service use that are more pro-rich than in most other European countries. To examine whether similar socio-economic patterning existed for mortality amenable to intervention in primary or specialist care, we investigated trends in amenable mortality by income group from 1992-2003. METHODS: We analysed trends in all cause, total disease and mortality amenable to health care using individual level data from the National Causes of Death Register for those aged 25 to 74 years in 1992-2003. These data were linked to sociodemographic data for 1990-2002 from population registers using unique personal identifiers. We examined trends in causes of death amenable to intervention in primary or specialist healthcare by income quintiles. RESULTS: Between 1992 and 2003, amenable mortality fell from 93 to 64 per 100,000 in men and 74 to 54 per 100,000 in women, an average annual decrease in amenable mortality of 3.6% and 3.1% respectively. Over this period, all cause mortality declined less, by 2.8% in men and 2.5% in women. By 2002-2003, amenable mortality among men in the highest income group had halved, but the socioeconomic gradient had increased as amenable mortality reduced at a significantly slower rate for men and women in the lowest income quintile. Compared to men and women in the highest income quintile, the risk ratio for mortality amenable to primary care had increased to 14.0 and 20.5 respectively, and to 8.8 and 9.36 for mortality amenable to specialist care. CONCLUSIONS: Our findings demonstrate an increasing socioeconomic gradient in mortality amenable to intervention in primary and specialist care. This is consistent with the existing evidence of inequity in healthcare use in Finland and provides supporting evidence of changes in the socioeconomic gradient in health service use and in important outcomes. The potential adverse effect of healthcare reform on timely access to effective care for people on low incomes provides a plausible explanation that deserves further attention.

Increased cancer mortality in diabetic people treated with insulin: a register-based follow-up study.

BACKGROUND: The national 10-year Development Programme for the Prevention and Care of Diabetes (DEHKO) was launched in Finland in 2000. The program focused on improving early diagnosis of type 2 diabetes and preventing diabetes-related complications. The FinDM database was established for epidemiological monitoring of diabetes and its complications. This study monitors mortality trends among people with diabetes during the DEHKO programme. METHODS: A database obtained from a compilation of several administrative national health registers was used to study mortality in people with diabetes in 1998-2007. Relative excess mortality between people with and without diabetes was analyzed using Poisson regression models. RESULTS: The number of diabetic people in Finland increased by 66% from 1997 reaching 284 832 in 2007. Like among non-diabetic people, all-cause mortality decreased in people with diabetes. Overall excess mortality remained high in people with diabetes; in 2003-2007 RRs in the non-insulin treated was 1.82 for men and 1.95 for women and in the insulin treated 3.45 and 4.29, and excess coronary heart disease mortality in the insulin treated: RR was 4.71 in men and 7.80 in women. A striking result was mortality from neoplasms; an increase in mortality emerged in almost every age group of insulin treated women. CONCLUSION: Compared to non-diabetic people our monitoring showed declining excess mortality in non-insulin treated diabetic people mainly due to a decrease in mortality from cardiovascular diseases. For insulin treated, relative overall excess mortality remained unchanged and mortality from neoplasms increased among women.

Socio-economic predictors of mortality among diabetic people.

BACKGROUND: The present study examines the role of six aspects of socio-economic status (income, occupational position, education, unemployment, living alone and type of residential area) in mortality among types 1 and 2 diabetic people in Finland. All-cause mortality and causes of deaths (for example, alcohol diseases) are assessed. METHODS: People with diabetes aged 30-79 years in 2000-03 were identified from national registers. The data comprised 528 734 person-years and 18 841 deaths. Relative mortality risks were obtained from Poisson regression models. RESULTS: Among type 1 diabetic men, mortality differences were largest for long-term unemployed (aged 30-64 years); RR 3.85 (3.00-4.94) compared with the employed, and for low (vs. high) income group; RR 1.96 (1.78-2.17). The findings were similar for type 2 men; RR 2.58 (2.16-3.09) for unemployment and 1.61 (1.53-1.69) for income. In type 1 diabetic women, largest differences were found according to unemployment; RR 3.32 (1.88-5.88) and education (lowest vs. highest education); RR 2.35 (1.84-3.00), but in type 2 diabetes, the strongest determinants were disposable income; RR 1.55 (1.44-1.66) and education; RR 1.50 (1.33-1.70). In most socio-economic determinants, relative differences were largest in deaths due to diabetes and alcohol diseases. CONCLUSIONS: Five aspects of socio-economic position were related to mortality among diabetic people in Finland. No systematic mortality differences were, however, found for type of municipality of residence. These findings together with the role of deaths from alcohol diseases and diabetes in mortality trends, indicate that different aspects of social disadvantage are important predictors of mortality among diabetic people.

Angina pectoris: relation of epidemiological survey to registry data.

BACKGROUND: Self-reported angina symptoms are collected in epidemiological surveys. We aimed at validating the angina symptoms assessed by the Rose Questionnaire against registry data on coronary heart disease. A further aim was to examine the sex paradox in angina implying that women report more symptoms, whereas men have more coronary events. DESIGN: Angina symptoms of 6601 employees of the City of Helsinki were examined using the postal questionnaire survey data combined with coronary heart disease registries. METHODS: The self-reported angina was classified as no symptoms, atypical pain, exertional chest pain, and stable angina symptoms. Reimbursed medications and hospital admissions were available from registries 10 years before the survey. Binomial regression analysis was used. RESULTS: Stable angina symptoms were associated with hospital admissions and reimbursed medications [prevalence ratio (PR), 6.75; 95% confidence interval (CI), 4.56-9.99]. In addition, exertional chest pain (PR, 5.31; 95% CI, 3.45-8.18) was associated with coronary events. All events were more prevalent among men than women (PR, 2.36; 95% CI, 1.72-3.25). CONCLUSION: The Rose Questionnaire remains a valid tool to distinguish healthy people from those with coronary heart disease. However, a notable part of those reporting symptoms have no confirmation of coronary heart disease in the registries. The female excess of symptoms and male excess of events may reflect inequality or delay in access to treatment, problems in identification and diagnosis, or more complex issues related to self-reported angina symptoms.

Diabetes and depression? Secular trends in the use of antidepressants among persons with diabetes in Finland in 1997-2007.

PURPOSE: The association between diabetes and depression is well demonstrated. Less is known about the trends in use of antidepressants in the rapidly growing population of diabetics. We examined trends in antidepressant medication use during 1997-2007 in Finland among persons with or without diabetes using register-based data on both diabetes and antidepressant use. METHODS: The diabetes population was obtained from the FinDM II database including 50,027 persons with insulin treated (ITDM) and 346,290 persons with non-insulin treated diabetes (NITDM) identified from several administrative registers. Data on persons without diabetes were obtained from the yearly population statistics and their antidepressant use from the register for refunded prescription medicine costs covering all medicine purchases of non-institutionalised residents. Differences in trends and prevalence were examined using the binomial regression model. RESULTS: Antidepressant use was more common among persons with diabetes in all age groups and each study year among both genders (prevalence ratios (RR) 1.4-2.2 for women and 1.7-2.2 for men). Prevalence was both higher (RR 2.0-2.2 women, 1.9-2.2 men), and increased more rapidly among younger persons with NITDM. CONCLUSIONS: The use of register data linked using unique personal identifiers allowed us to identify a total cohort of persons with diabetes, to separate between ITDM and NITDM patients and to examine patterns of antidepressant use in populations with and without diabetes during an 11 year study period. Our results suggest that more attention should be focused on psychological well-being in those with diabetes and especially young people in risk of type 2 diabetes.
