Kinds of National Patient Registry Selected AbstractsHospitalizations for opioid poisoning: a nation-wide population-based study in Denmark, 1998,2004ADDICTION, Issue 1 2009Anne-Mette Bay Bjørn ABSTRACT Aims To assess hospitalization rates (HR) for poisoning with heroin, methadone or strong analgesics and relate them to quantities of prescribed methadone and strong analgesics in Denmark between 1998 and 2004. Design Population-based ecological study. Settings We extracted data on all emergency department visits and hospital admissions registered in the Danish National Patient Registry with a diagnosis of poisoning with heroin (n = 1688), methadone (n = 173) or strong analgesics (n = 384). To ascertain sale of prescribed medications we used data from the Danish Medicines Agency. Measurements Age- and gender-standardized HR and defined daily doses (DDD) per 1000 people per day. Findings HR for heroin poisoning was 4.4 [95% confidence interval (CI): 3.8,4.9] per 100 000 person-years (p-y) in 1998 and 4.6 (CI: 4.0,5.2) per 100 000 p-y in 2004. HR for methadone poisoning increased from 0.1 (CI: 0.0,0.2) per 100 000 p-y in 1998 to 1.1 (CI: 0.8,1.4) per 100 000 p-y in 2004. HR for poisoning with strong analgesics increased from 0.6 (CI: 0.4,0.9) per 100 000 p-y in 1998 to 2.1 (CI: 1.8,2.6) per 100 000 p-y in 2004. The sale of prescribed strong analgesics (5.0 DDD per 1000 people per day in 1998 to 5.9 DDD in 2004) and methadone (3.0 DDD per 1000 people per day in 1998 to 3.4 DDD in 2004) increased slightly between 1998 and 2004. Conclusion Increasing sale of prescribed methadone and strong analgesics coincided with increasing HRs of poisoning with these drugs, whereas HR of heroin poisoning varied. Further longitudinal studies are important for the guidance of future policy making. [source] Smoking and venous thromboembolism: a Danish follow-up studyJOURNAL OF THROMBOSIS AND HAEMOSTASIS, Issue 8 2009M. T. SEVERINSEN Summary.,Background: Large-scale prospective studies are needed to assess whether smoking is associated with venous thromboembolism (VTE) (i.e. deep venous thrombosis and pulmonary embolism) independently of established risk factors. Objective: To investigate the association between smoking and the risk of VTE among middle-aged men and women. Methods: From 1993 to 1997, 27 178 men and 29 875 women, aged 50,64 years and born in Denmark, were recruited into the Danish prospective study ,Diet, Cancer and Health'. During follow-up, VTE cases were identified in the Danish National Patient Registry. Medical records were reviewed and only verified VTE cases were included in the study. Baseline data on smoking and potential confounders were included in gender stratified Cox proportional hazard models to asses the association between smoking and the risk of VTE. The analyses were adjusted for alcohol intake, body mass index, physical activity, and in women also for use of hormone replacement therapy. Results: During follow-up, 641 incident cases of VTE were verified. We found a positive association between current smoking and VTE, with a hazard ratio of 1.52 (95% CI, 1.15,2.00) for smoking women and 1.32 (95% CI, 1.00,1.74) for smoking men, and a positive dose-response relationship. Former smokers had the same hazard as never smokers. Conclusions: Smoking was an independent risk factor for VTE among middle-aged men and women. Former smokers have the same risk of VTE as never smokers, indicating acute effects of smoking, and underscoring the potential benefits of smoking cessation. [source] Pseudomonas aeruginosa and other predictors of mortality and morbidity in young children with cystic fibrosis,PEDIATRIC PULMONOLOGY, Issue 2 2002Julia Emerson MD Abstract We conducted a registry-based study to determine prognostic indicators of 8-year mortality and morbidity in young children with cystic fibrosis (CF). Patients ages 1,5 years from the 1990 U.S. Cystic Fibrosis Foundation (CFF) National Patient Registry served as the study cohort (N,=,3,323). Registry data provided information on baseline characteristics in 1990, 8-year mortality, and clinical outcomes in 1998. P. aeruginosa respiratory infection was found to be a major predictor of morbidity and mortality. The 8-year risk of death was 2.6 times higher in patients who had respiratory cultures positive for P. aeruginosa in 1990 (95% confidence interval 1.6, 4.1) than in children without P. aeruginosa in their respiratory cultures. Culture-positive patients in 1990 also had a significantly lower percent predicted forced expiratory volume in 1 sec (FEV1) and weight percentile at follow-up, and they had an increased risk of continued P. aeruginosa respiratory infection and hospitalization for acute respiratory exacerbation in 1998. Among the other predictors of increased morbidity and mortality were lower baseline weight percentiles and number of CF-related hospitalizations during the baseline year. These findings confirm reports from previous smaller studies of outcomes among young children with CF, and highlight the potential to decrease the morbidity and mortality of young patients with CF through early intervention.

[source] Intake of vitamin C and E in pregnancy and risk of pre-eclampsia: prospective study among 57 346 womenBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 7 2009ÅK Klemmensen Objective, It has been suggested that vitamin C, alone or in combination with vitamin E, may protect against pre-eclampsia, whereas the safety of high-dose vitamin E supplements has been questioned. We investigated dietary intakes of vitamins C and E to see if they correlated with the incidence of pre-eclampsia. Design, Prospective cohort study. Setting, The Danish National Birth Cohort; a population-based pregnancy cohort; analyses were based on 57 346 pregnancies. Methods, Vitamin intake was estimated from a food frequency questionnaire completed in gestational week 25, recording intake from diet and supplements during the previous four weeks. Pre-eclampsia diagnoses were obtained from the Danish National Patient Registry; we worked with two entities, ,pre-eclampsia (all types)' and ,severe pre-eclampsia/eclampsia/HELLP'. We adjusted for confounding factors by logistic regression. Main outcome measures, A small increase in the incidence of severe disease was also seen in the group of women (64, n = 49 373) with a high intake of vitamin E from supplements and dietary sources. Results, The incidence of ,pre-eclampsia (all types)' did not correlate with dietary vitamin C and E intake. There was a decreasing trend (P = 0.01) in the incidence of ,severe pre-eclampsia/eclampsia/HELLP' with increasing dietary vitamin C intake; with an intake of 130,170 mg/day as reference, odds ratios ranged from 1.21 (95% confidence interval 0.83 to 1.75) for an intake below 70 mg/day to 0.70 (0.40 to 1.23) for an intake exceeding 275 mg/day (total n = 57 346). For vitamin E intake aggregated from diet and supplements (n = 49 373), with an intake of 10.5,13.5 mg/day as reference, the ,severe pre-eclampsia/eclampsia/HELLP' odds ratio was 1.46 (1.02 to 2.09) for an intake exceeding 18 mg/day. Conclusions, Low dietary intake of vitamin C was associated with a trend towards an increased incidence of either severe pre-eclampsia, eclampsia or HELLP. A small increase in the incidence of severe disease was also seen in the group of women with a high intake of vitamin E from supplements and dietary sources.

Jennum Jennum P, Kjellberg J. The socio-economical burden of hypersomnia. Acta Neurol Scand: 2010: 121: 265,270. © 2009 The Authors Journal compilation © 2009 Blackwell Munksgaard. Objectives,,, In the absence of socio-economical consequences of hypersomnia this study addresses the factual indirect and direct costs. Methods,,, Two thousand two hundred and eight patients with a hypersomnia diagnosis from 1998 to 2005 were identified in the Danish national patient registry (NPR), each compared with 4 age and gender adjusted, randomly chosen citizens selected from the Civil Registration System Statistics. The health cost was decomposed in direct and indirect yearly costs, including labor supply and social transfer payments. Direct costs included frequencies and costs of discharges and outpatient use by cost weights according to diagnosis related groups and specific outpatient prices based on data from The Danish Ministry of Health. The use of and costs of drugs was based on data from the Danish Medicines Agency. The frequencies and costs from primary sectors were based on data from The National Health Security. Indirect costs were based on income data from the coherent social statistics (CSS). Results,,, Patients with hypersomnia presented significant higher health related contact rate, expenses and medication use. No differences were identified in employment and income. The yearly sum of direct and indirect costs were yearly ,3402 vs. ,1212 in controls (P < 0.001), corresponding to a yearly excess costs ,2190. The patients presented higher transfer income, total ,889. Conclusion,,, Hypersomnia patient present higher health and medication uses, and social transfer income and thus represent a significant socio-economical burden. [source] | ||||||||||
