High Incidence of Pulmonary Tuberculosis a Decade after Immigration, Netherlands

Incidence rates of pulmonary tuberculosis among immigrants from high incidence countries remain high for at least a decade after immigration into the Netherlands. Possible explanations are reactivation of old infections and infection transmitted after immigration. Control policies should be determined on the basis of the as-yet unknown main causes of the persistent high incidence

The Equity Impact of Community Women's Groups to Reduce Neonatal Mortality: A Meta-analysis of Four Cluster Randomized Trials

Socioeconomic inequalities in neonatal mortality are substantial in many developing countries. Little is known about how to address this problem. Trials in Asia and Africa have shown strong impacts on neonatal mortality of a participatory learning and action intervention with women’s groups. Whether this intervention also reduces mortality inequalities remains unknown. We describe the equity impact of this women’s groups intervention on the neonatal mortality rate (NMR) across socioeconomic strata. We conducted a meta-analysis of all four participatory women’s group interventions that were shown to be highly effective in cluster randomized trials in India, Nepal, Bangladesh and Malawi. We estimated intervention effects on NMR and health behaviours for lower and higher socioeconomic strata using random effects logistic regression analysis. Differences in effect between strata were tested. Analysis of 69120 live births and 2505 neonatal deaths shows that the intervention strongly reduced the NMR in lower (50–63% reduction depending on the measure of socioeconomic position used) and higher (35–44%) socioeconomic strata. The intervention did not show evidence of ‘elite-capture’: among the most marginalized populations, the NMR in intervention areas was 63% lower [95% confidence interval (CI) 48–74%] than in control areas, compared with 35% (95% CI: 15–50%) lower among the less marginalized in the last trial year (P-value for difference between most/less marginalized: 0.009). The intervention strongly improved home care practices, with no systematic socioeconomic differences in effect. Participatory women’s groups with high population coverage benefit the survival chances of newborns from all socioeconomic strata, and perhaps especially those born into the most deprived households

Spatiotemporal dynamics of hemorrhagic fever with renal syndrome, Beijing, People's Republic of Chin

We used geographic information systems to characterize the dynamic change in spatial distribution of hemorrhagic fever with renal syndrome (HFRS) in Beijing, People's Republic of China. The seasonal variation in its incidence was observed by creating an epidemic curve. HFRS was associated with developed land, orchards, and rice paddies

Comparison of cohort smoking intensities in Denmark and the Netherlands

OBJECTIVE: To assess the usefulness of the general framework of the smoking epidemic. METHODS: We use lung cancer mortality as an indicator for smoking intensity and employ an age-cohort model to accommodate the long-lasting and cumulative effects. RESULTS: Dutch males have higher risks than Danish males, but the risks for the younger cohorts have been declining faster in the Netherlands than in Denmark. Danish women have about twice the risk of Dutch women, and in both countries the risks for the younger cohorts are increasing. The smoking epidemic began at about the same time in Denmark and the Netherlands. Dutch males, however, seem to have smoked more but to have given up smoking more quickly than Danish males. Danish females were quicker to take up smoking than Dutch females. CONCLUSIONS: Within the general framework of the smoking epidemic, differences in timing and levels can produce large differences between countries. For the purposes of assessing smoking-related risks, including projections, the smoking epidemic framework therefore has to be tailored to each study population

Measuring Quality Improvement in Acute Ischemic Stroke Care: Interrupted Time Series Analysis of Door-to-Needle Time

Background: In patients with acute ischemic stroke, early treatment with recombinant tissue plasminogen activator (rtPA) improves functional outcome by effectively reducing disability and dependency. Timely thrombolysis, within 1 h, is a vital aspect of acute stroke treatment, and is reflected in the widely used performance indicator ‘door-to-needle time' (DNT). DNT measures the time from the moment the patient enters the emergency department until he/she receives intravenous rtPA. The purpose of the study was to measure quality improvement from the first implementation of thrombolysis in stroke patients in a university hospital in the Netherlands. We further aimed to identify specific interventions that affect DNT. Methods: We included all patients with acute ischemic stroke consecutively admitted to a large university hospital in the Netherlands between January 2006 and December 2012, and focused on those treated with thrombolytic therapy on admission. Data were collected routinely for research purposes and internal quality measurement (the Erasmus Stroke Study). We used a retrospective interrupted time series design to study the trend in DNT, analyzed by means of segmented regression. Results: Between January 2006 and December 2012, 1,703 patients with ischemic stroke were admitted and 262 (17%) were treated with rtPA. Patients treated with thrombolysis were on average 63 years old at the time of the stroke and 52% were male. Mean age (p = 0.58) and sex distribution (p = 0.98) did not change over the years. The proportion treated with thrombolysis increased from 5% in 2006 to 22% in 2012. In 2006, none of the patients were treated within 1 h. In 2012, this had increased to 81%. In a logistic regression analysis, this trend was significant (OR 1.6 per year, CI 1.4-1.8). The median DNT was reduced from 75 min in 2006 to 45 min in 2012 (p Conclusion and Implications: The DNT steadily improved from the first implementation of thrombolysis. Specific explanations for this improvement require further study, and may relate to the combined impact of a series of structural and logistic interventions. Our results support the use of performance measures for internal communication. Median DNT should be used on a monthly or quarterly basis to inform all professionals treating stroke patient of their achievements

Post-1950 mortality trends and medical care: Gains in life expectancy due to declines in mortality from conditions amenable to medical intervention in the Netherlands

In order to assess the impact of medical care innovations on post-1950 mortality in The Netherlands, we analysed trends in mortality from a selection of conditions suggested by Rutstein et al.'s lists of "unnecessary untimely mortality". This selection covers 11 types of innovation, and includes 35 conditions which have become amenable to medical care. Loglinear regression analysis shows that for most of these conditions mortality declined during each of two subperiods (1950-1968; 1969-1984). Mortality decline accelerated in the second subperiod for many conditions. Reductions in mortality from these conditions between 1950/54 and 1980/84 added 2.96 and 3.95 years to life expectancy at birth of Dutch males and Dutch females respectively. A priori evidence indicates that these mortality reductions are due to some extent to 'spontaneous' incidence declines. Although the exact contribution of medical care innovations to these changes in mortality thus cannot be determined, the impact of medical care on post-1950 mortality in The Netherlands could well have been substantial.mortality medical care loglinear regression analysis Netherlands

The Contribution of Specific Diseases to Educational Disparities in Disability-Free Life Expectancy

Objectives. We examined the contribution that specific diseases, as causes of both death and disability, make to educational disparities in disability-free life expectancy (DFLE). Methods. We used disability data from the Belgian Health Interview Survey (1997) and mortality data from the National Mortality Follow-Up Study (1991–1996) to assess education-related disparities in DFLE and to partition these differences into additive contributions of specific diseases. Results. The DFLE advantage of higher-educated compared with lower-educated persons was 8.0 years for men and 5.9 years for women. Arthritis (men, 1.3 years; women, 2.2 years), back complaints (men, 2.1 years), heart disease/stroke (men, 1.5 years; women, 1.6 years), asthma/chronic obstructive pulmonary disease (COPD) (men, 1.2 years; women, 1.5 years), and “other diseases” (men, 2.4 years) contributed the most to this difference. Conclusions. Disabling diseases, such as arthritis, back complaints, and asthma/COPD, contribute substantially to differences in DFLE by education. Public health policy aiming to reduce existing disparities in the DFLE and to improve population health should not only focus on fatal diseases but also on these nonfatal diseases
