Are the findings in the Swedish National Total Hip Arthroplasty Register valid? A comparison between the Swedish National Total Hip Arthroplasty Register, the National Discharge Register, and the National Death Register.

The Swedish National Total Hip Arthroplasty (THA) Register was initiated in 1979, and it is one of the oldest quality registers in the world. The register covers all hospitals in Sweden, and today it contains > 205,000 hip arthroplasties. The failure endpoint definition in the register is revision. There is no information about quality of life and mortality. The aim of this study was to validate the results presented by the Swedish THA register by comparison with the Discharge register (the Swedish National Board of Health and Welfare) and to study mortality after hip arthroplasties. All hip arthroplasties from the Discharge register, performed in 1986 and thereafter, were compared with the Swedish THA register. Epidemiologic parameters, including mortality, were documented from the Swedish Death register. The mortality for primary THAs for men was 1% higher and for women 6% higher when compared with an age-matched and sex-matched cohort. For revision, the numbers were 7% and 9% higher. The risk for death compared with an age-matched and sex-matched population was lower for patients with osteoarthrosis treated with hip arthroplasty. The results with revision as failure endpoint showed that the Swedish THA register is reliable. The register includes >95% of the primary and revision THAs performed in Sweden between 1986 and 1995.

[Anesthesiologists in France. First results of the national survey conducted in 1999 by the French College of Anesthesiologist, The French National Society of Anesthesia and Intensive Care with the scientific support of the National Institute for Demographic Studies].

OBJECTIVES: Fears related to the future of anaesthesia manpower in France have led the French College of Anaesthesiologists (Cfar) and the French Society of Anaesthesia and Intensive Care (Sfar), in scientific partnership with the National Institute for Demographic Studies (Ined), to set-up a national survey among French anaesthetists (MAR) practicing in France, to describe their demographic evolution and to analyse their professional activities. METHODS: The survey was based on a personal questionnaire, filled by each individual, approved by the National Commission on Informatics and Freedoms (CNIL). The survey was conducted in November 1998, in the 1484 hospitals, public (590) and private (894) where anaesthetics are performed, under the control of local and regional referents. RESULTS: The anaesthesiologists positions count gave a total of 9741 positions shared between 5694 in public practice (58%), 3569 in private practice (37%) and 478 in private hospitals taking part to the national health service-PSPH (5%). The evaluation of the number of anaesthesiologists from the number of positions has made necessary a methodology of rectification of the survey to take in account the lack of response and the multiple sites of activity. The survey allows an evaluation of around 8876 physicians practising anaesthesia and intensive care in France at the beginning of 1999, among them 216 overseas. This census is in concordance with the count made by the Medical Council--Ordre des médecins--which published a number of 8716 anaesthesiologists in France, and 234 overseas, at the 1st January 1999, corresponding to a total of 8950. The annual demographic growth has felt from 9% per year, before 1989, to reach the level zero, in 1999. The masculinisation of the speciality is growing with a proportion of 35.7% of females, as well as ageing, the overage of age increasing from 42.8 in 1989 to 45.9 years in 1999. The pyramid of ages does not correspond to a growing population but to ageing people due to a decrease of the youngest classes. The medical density of 14.75 anaesthesiologists for 100,000 inhabitants in 1999, compared to 12.9 in 1989, is slightly above the European average, but the geographic distribution is very unequal between north and south, the large cities, centre of a university hospital, and the smaller one even if a reduction of differences is observed. The study and the analysis of professional activities bring important data to take in account side of demographic evolution. CONCLUSION: The demographic evolution must integrate non-only the reduction of the entries in the speciality, of the retirements, but also the sociological evolutions linked to the working time reduction. The solutions face to the promised shortcut of manpower consist of a reorganisation of the structures, a new definition of tasks and managements, without the possibility to avoid and adjustment of the anaesthesiologists population.

Demography of French anaesthesiologists. Results of a national survey by the French College of Anaesthesiologists (CFAR) and the French National Society of Anaesthesia and Intensive Care (SFAR), supported by the National Institute for Demographic Studies (INED).

BACKGROUND AND OBJECTIVE: The perception of a looming manpower shortage led the French College of Anaesthesiologists (CFAR) and the French Society of Anaesthesia and Intensive Care (SFAR), with assistance from the National Institute for Demographic Studies (INED), to conduct a national survey of French anaesthesiologists in order to determine precise physician characteristics data, analyse professional practices and project future service provision. METHODS: The survey was based on self-administered individual questionnaires, approved by the National Committee on Informatics and Freedom (CNIL). The survey was carried out at the end of 1998 among 1484 hospitals (590 public and 894 private), under the supervision of local referees and regional co-ordinators. RESULTS: Of 9741 anaesthesiologists' posts, 5694 (58%) are in public hospitals, 3569 (37%) in private practice and 478 (5%) in private hospitals within the National Health Service, i.e. the participant au service public hospitalier (PSPH). Complex validation of the results was necessary to account for the missing responses and multiple sites of activity. The survey identified 8876 specialists practising anaesthesia and intensive care in France at the beginning of 1999, including 216 in French overseas territories. This figure is consistent with that published by the Medical Council (Ordre des Médecins) on 1 January 1999, identifying 8950 anaesthesiologists in France, including 234 in the overseas territories. Annual growth in the anaesthesiologist population has fallen from 9% pre-1989 to 0% in 1999. Male anaesthesiologists outnumber females (35.7%). The average age has risen from 42.8 yr in 1989 to 45.9yr in 1999. The age distribution of anaesthesiologists has become bell shaped, reflecting reduced numbers of younger practitioners. There are currently 14.75 anaesthesiologists per 100 000 people (compared to 12.9 in 1989), a figure slightly above the European average, but there is considerable geographical inequality between the north and south of France, with increased concentrations in large cities that contain university hospitals. CONCLUSIONS: Future service provision must take account of falling numbers of new anaesthesiologists and an increase in retirements, but must also include changes in working practices, such as the European Working Time Directive. If anaesthesia manpower shortages are to be avoided, there must be a restructuring of the work-place, a redefinition of tasks and improved management of working time.

Comorbidity of rosacea and depression: an analysis of the National Ambulatory Medical Care Survey and National Hospital Ambulatory Care Survey--Outpatient Department data collected by the U.S. National Center for Health Statistics from 1995 to 2002.

BACKGROUND: Psychogenic factors have been considered to be important in the exacerbation and possibly the onset of rosacea. However, there are very few studies that have reported conclusive findings. OBJECTIVES: To examine the association between rosacea and major depressive disease, a common and usually treatable psychiatric disorder. METHODS: Data from 1995 to 2002, collected by the National Ambulatory Medical Care Survey and the outpatient component of the National Hospital Ambulatory Care Survey, which are both nationally representative surveys of healthcare visits in the U.S.A., were studied. The basic sampling unit in both surveys is the patient visit or encounter. A "Rosacea" variable was created by grouping all rosacea (ICD-9-CM code 695.3) visits and a "Depression" variable was created by grouping the patient visits related to major depressive disorder (ICD-9-CM codes 296.2, 296.3 and 311). As alcohol abuse has been implicated in rosacea, and alcohol can confound symptoms of depression, an "Alcohol" variable was created by grouping all ICD-9-CM codes related to alcohol dependence and abuse (codes 303, 303.0, 303.9 and 305.0). All analyses were conducted using the Complex Samples module of SPSS version 13, to account for the multistage probability sampling design used to collect the data. RESULTS: The weighted data were representative of over 608 million dermatology visits between 1995 and 2002. Logistic regression analysis using "Rosacea" as the dependent variable and age, sex, "Alcohol" and "Depression" as independent variables revealed that the odds ratio for depressive disease in the rosacea group was 4.81 (95% confidence interval 1.39-16.62). The association between "Alcohol" and "Rosacea" was not significant. CONCLUSIONS: The comorbidity between major depressive disease and rosacea may have important clinical implications. Alcohol abuse does not appear to play a significant role in this association.

[Determination of one national standard for children with congenital anomalies in the National Obstetrical Registry and in the National Neonatal Registry].

OBJECTIVE: To determine if the birth prevalence data on congenital malformations in the national perinatal registries, the Landelijke Verloskunde Registratie (LVR) (National Obstetrical Registry) and the Landelijke Neonatologie Registratie (LNR) (National Neonatological Registry), can be combined into one nationwide database, and if so to determine the validity of this database. DESIGN: Descriptive. SETTING: TNO Prevention and Health, Leiden, the Netherlands. METHODS: Investigation of the registered number of congenital malformations in the LVR/LNR, the amount of overlapping and the possibility of combining the LVR and LNR into one nationwide database. The validity of this database was evaluated by comparing the total number of registered children with the total number expected in the Netherlands. Furthermore the total number of children registered in the nationwide database was compared with children registered by the European registration of congenital anomalies and twins (EUROCAT) in the Northern Netherlands. RESULTS: The LVR and LNR were mostly complementary with respect to the registration of congenital anomalies and could be combined to one nationwide database. For sixteen important diagnoses this nationwide database contained approximately 87% of the total number expected in the Netherlands. Comparing this database with the data of EUROCAT in the Northern Netherlands showed that one-third of these congenital malformations (n = 229 in 217 children) were registered in both systems, while 99 (43%) were only registered by EUROCAT and 50 (22%) only by the nationwide database. CONCLUSION: It was possible to create a nationwide database, which can supplement the regional EUROCAT data with nationwide data on sixteen important diagnoses of congenital malformations.

Trends in serum cholesterol levels among US adults aged 20 to 74 years. Data from the National Health and Nutrition Examination Surveys, 1960 to 1980. National Center for Health Statistics-National Heart, Lung, and Blood Institute Collaborative Lipid Group.

From 1960 to 1980, serum cholesterol levels were determined for three different national surveys of the US noninstitutionalized population aged 20 to 74 years conducted by the National Center for Health Statistics, Hyattsville, Md. Serum cholesterol determinations for each of the three surveys were standardized to the Abell-Kendall laboratory method. Age-adjusted mean serum cholesterol levels decreased by 6 to 8 mg/dL (0.16 to 0.21 mmol/L), or 3% to 4%, between the 1960 to 1962 and the 1976 to 1980 surveys. For men, this represented a decrease from 217 mg/dL (5.61 mmol/L) to 211 mg/dL (5.46 mmol/L) and for women, a decrease from 223 mg/dL (5.77 mmol/L) to 215 mg/dL (5.56 mmol/L). Both declines were statistically significant. Mean serum cholesterol level decreased significantly in whites but not in blacks, and in all education subgroups for whites except men with less than nine years of education. In addition, the percentage of men and women with high-risk and moderate-risk cholesterol levels decreased during this period.

Asthma in pregnancy. National Asthma Education Program Working Group on Asthma and Pregnancy. National Institutes of Health, National Heart, Lung and Blood Institute.

This manuscript is a summary of a comprehensive report dealing with asthma and pregnancy issued by the working group on Asthma and Pregnancy, National Institutes of Health (NIH), National Heart, Lung, and Blood Institute. The report was developed by a panel of obstetricians, pharmacologists, internists, allergists, and pulmonologists, who met over an 18-month period under the auspices of the NIH. Undertreatment of pregnant asthmatics, partially because of unfounded fears of adverse pharmacologic effects on the developing fetus, remains the major problem in the management of asthma during pregnancy in the United States. The four key components of asthma management during pregnancy are: 1) objective assessment of maternal lung function and fetal well-being, 2) avoidance or control of environmental precipitating factors, 3) pharmacologic therapy, and 4) patient education.

Pre-hospital 12-lead electrocardiography programs: a call for implementation by emergency medical services systems providing advanced life support--National Heart Attack Alert Program (NHAAP) Coordinating Committee; National Heart, Lung, and Blood Institute (NHLBI); National Institutes of Health.

Emergency medical services (EMS) providers who administer advanced life support should include diagnostic 12-lead electrocardiography programs as one of their services. Evidence demonstrates that this technology can be readily used by EMS providers to identify patients with ST-segment elevation myocardial infarction (STEMI) before a patient's arrival at a hospital emergency department. Earlier identification of STEMI patients leads to faster artery-opening treatment with fibrinolytic agents, either in the pre-hospital setting or at the hospital. Alternatively, a reperfusion strategy using percutaneous coronary intervention can be facilitated by use of pre-hospital 12-lead electrocardiography (P12ECG). Analysis of the cost of providing this service to the community must include consideration of the demonstrated benefits of more rapid treatment of patients with STEMI and the resulting time savings advantage shown to accompany the use of P12ECG programs.

Hospitalization for community-acquired pneumonia in Alberta First Nations Aboriginals compared with non-First Nations Albertans.

BACKGROUND: The rates and outcomes of hospital admission for community-acquired pneumonia between First Nations Aboriginal and non-First Nations groups were compared. METHODS: Alberta administrative hospital abstracts from April 1, 1997, to March 31, 1999, were analyzed, and each case of a First Nations Aboriginal person with pneumonia was matched by age and sex with three non-First Nations persons with pneumonia. RESULTS: The First Nations Aboriginal age and sex-adjusted hospital discharge rate was 22 per 1000 (95% CI 20.7 to 23.6) compared with 4.4 per 1000 (95% CI 4.4 to 4.5) for the general population of Alberta. After accounting for comorbidity and severity of pneumonia, in-hospital mortality and hospital length of stay were lower for First Nations Aboriginals compared with the matched non-First Nations group (odds ratio 0.49; 95% CI 0.37 to 0.66, and odds ratio 0.87; 95% CI 0.79 to 0.97, respectively). The odds for 30-day hospital readmission were higher in First Nations Aboriginals compared with the non-First Nations group (odds ratio 1.42; 95% CI 1.21 to 1.68). The cost per hospital admission for First Nations Aboriginals was 94% of the average cost for the matched non-First Nations group (CDN4,206 dollars). However, their median daily cost was 1.25 times higher (95% CI 1.14 to 1.36) than the matched non-First Nations group. CONCLUSIONS: First Nations Aboriginals had higher rates of hospitalization, rehospitalization and hospital costs for community-acquired pneumonia than non-First Nations Albertans. It was unlikely that the high rate of hospitalizations in First Nations Aboriginals was due to more severe pneumonia or greater comorbidity. Other unexplained factors increase the burden of this disease in First Nation Aboriginals.
