Objective. In countries with widespread prostate cancer screening there has been strong stage migration, but little is known about changes within clinical risk categories. Such data are important for the proper interpretation of studies that recruited cases in an earlier era. The purpose of this study was to examine stage migration between and within clinical risk categories. Material and methods. Using the population-based National Prostate Cancer Register (NPCR) of Sweden, changes in the distribution of prostate-specific antigen (PSA), Gleason score, tumor stage and volume overall between and within clinical risk categories were examined in 120 228 prostate cancer cases diagnosed from 1998 to 2011. Results. Between 1998 and 2011, there was a two-fold increase in the proportion of low-risk prostate cancer (stage T1/T2, Gleason score 2-6 and PSA <10 ng/ml), from 14% to 28%, and more than a two-fold decrease in the proportion of metastatic disease, from 25% to 11%. The proportion of men in the low-risk category with T1c tumors increased two-fold, from 36% to 71%, and PSA levels between 4 and 6 ng/ml increased from 24% to 38%; T2 tumors decreased from 39% to 20% and PSA between 8 and 10 ng/ml decreased from 24% to 15%. The proportion of men with less than 25% of cores involved with cancer increased from 41% to 52% between 2003-2006 and 2007-2011. Conclusions. Low-risk cases today have substantially lower tumor volume and PSA levels than low-risk cases diagnosed in 1998, indicating that outcomes in studies that recruited cases in previous decades represent worst case scenarios. © 2014 Informa Healthcare.

Purpose: Several studies indicate that the medical burden of fatal adverse drug reactions (FADRs) is significant, but the preventability of FADRs in the general population is largely unknown. The aim of this study was to determine the proportion of preventable FADRs and preventable fatal drug poisonings (FDPs) in a Swedish population. Methods: Previously, a population-based sample of 1574 deceased subjects was scrutinised for FADRs and FDPs using relevant case records, including death certificates, medical charts and medico-legal files. Forty-nine cases (3%) of FADRs and nine cases (0.6%) of FDPs were identified in 57 subjects. In this study, the preventability of all these identified FADRs and FDPs was evaluated by clinical experts in a stepwise manner, applying a set of predefined and well established preventability criteria. Only cases for which consensus was achieved were included in the study. Results: Of 49 FADRs, 14% (seven fatalities) was considered definitely or possibly preventable and four of these were due to the presence of a contraindication for the drug. All nine FDPs were considered possibly preventable. As one subject had a combination of an FADR and an FDP, a total of 15 persons (26%) were considered having a definitely or possibly preventable FADR or FDP, corresponding to 0.95% of all deceased subjects in Sweden. Conclusions: The results of this study indicate that approximately one fourth of FADRs and FDPs could be prevented. Therefore, an increased awareness of the possibility to reduce the risk of fatal events due to pharmaceutical drugs is warranted. Copyright © 2009 John Wiley & Sons, Ltd. Source

Background: Acute coronary syndromes, including myocardial infarction and unstable angina, are important causes of premature mortality, morbidity and hospital admissions. Acute coronary syndromes consume large amounts of health care resources, and have a major negative economic and social impact through days lost at work, support for disability, and coping with the psychological consequences of illness. Several registries have shown that evidence based treatments are under-utilised in this patient population, particularly in high-risk patients. There is evidence that systematic educational programmes can lead to improvement in the management of these patients. Since application of the results of important clinical trials and expert clinical guidelines into clinical practice leads to improved patient care and outcomes, we propose to test a quality improvement programme in a general group of hospitals in Europe.Methods/Design: This will be a multi-centre cluster-randomised study in 5 European countries: France, Spain, Poland, Italy and the UK. Thirty eight hospitals will be randomised to receive a quality improvement programme or no quality improvement programme. Centres will enter data for all eligible non-ST segment elevation acute coronary syndrome patients admitted to their hospital for a period of approximately 10 months onto the study database and the sample size is estimated at 2,000-4,000 patients. The primary outcome is a composite of eight measures to assess aggregate potential for improvement in the management and treatment of this patient population (risk stratification, early coronary angiography, anticoagulation, beta-blockers, statins, ACE-inhibitors, clopidogrel as a loading dose and at discharge). After the quality improvement programme, each of the eight measures will be compared between the two groups, correcting for cluster effect.Discussion: If we can demonstrate important improvements in the quality of patient care as a result of a quality improvement programme, this could lead to a greater acceptance that such programmes should be incorporated into routine health training for health professionals and hospital managers. © 2010 Flather et al; licensee BioMed Central Ltd.

Purpose: Prostate cancer (PCa) incidence and prognosis vary geographically. We examined possible differences in PCa risk by clinical risk category between native-born and immigrant populations in Sweden. Our hypothesis was that lower PSA-testing uptake among foreign-born men would result in lower rates of localized disease, and similar or higher risk of metastatic disease. Methods: Using the Prostate Cancer database Sweden, we identified 117,328 men with PCa diagnosed from 1991 to 2008, of which 8,332 were foreign born. For each case, 5 cancer-free matched controls were randomly selected from the population register. Conditional logistic regression was used to compare low risk, intermediate risk, high risk, regionally metastatic, and distant metastatic PCa based upon region of origin. Results: Across all risk categories, immigrants had significantly lower PCa risk than native-born Swedish men, except North Americans and Northern Europeans. The lowest PCa risk was observed in men from the Middle East, Southern Europe, and Asia. Multivariable adjustment for socioeconomic factors and comorbidities did not materially change risk estimates. Older age at immigration and more recent arrival in Sweden were associated with lower PCa risk. Non-native men were less likely to be diagnosed with PCa through PSA testing during a health checkup. Conclusions: The risk for all stages of PCa was lower among first-generation immigrants to Sweden compared with native-born men. Older age at immigration and more recent immigration were associated with particularly low risks. Patterns of PSA testing appeared to only partly explain the differences in PCa risk, since immigrant men also had a lower risk of metastatic disease. © 2012 Springer Science+Business Media Dordrecht.

Background: An online health-promoting community (OHPC) has the potential to promote health and advance new means of dialogue between public health representatives and the general public. The aim of this study was to examine what aspects of an OHPC that are critical for satisfying the needs of the user community and public health goals and service capabilities. Methods. Community-based participatory research methods were used for data collection and analysis, and participatory design principles to develop a case study OHPC for adolescents. Qualitative data from adolescents on health appraisals and perspectives on health information were collected in a Swedish health service region and classified into categories of user health information exchange needs. A composite design rationale for the OHPC was completed by linking the identified user needs, user-derived requirements, and technical and organizational systems solutions. Conflicts between end-user requirements and organizational goals and resources were identified. Results: The most prominent health information needs were associated to food, exercise, and well-being. The assessment of the design rationale document and prototype in light of the regional public health goals and service capabilities showed that compromises were needed to resolve conflicts involving the management of organizational resources and responsibilities. The users wanted to discuss health issues with health experts having little time to set aside to the OHPC and it was unclear who should set the norms for the online discussions. Conclusions: OHPCs can be designed to satisfy both the needs of user communities and public health goals and service capabilities. Compromises are needed to resolve conflicts between users' needs to discuss health issues with domain experts and the management of resources and responsibilities in public health organizations. © 2013 Ekberg et al.; licensee BioMed Central Ltd.
