Similar geographic variations of mortality and hospitalization associated with IBD and Clostridium difficile colitis

INFLAMMATORY BOWEL DISEASES, Issue 3 2010
Amnon Sonnenberg MD
Abstract Background: Superinfection with Clostridium difficile can aggravate the symptoms of preexisting inflammatory bowel disease (IBD). The study served to assess whether the geographic variation of IBD within the United States might be influenced by C. difficile infection. Methods: Hospitalization data of the Healthcare Cost and Utilization Project (HCUP) from 2001,2006 and mortality data from 1979,2005 of the US were analyzed by individual states. Hospitalization and mortality associated with Crohn's disease (CD), ulcerative colitis (UC), and C. difficile colitis were correlated with each other, using weighted least square linear regression with the population size of individual states as weight. Results: Among the hospitalization rates, there were strong correlations between both types of IBD, as well as each type of IBD with C. difficile colitis. Similarly, among the mortality rates there were strong correlations between both types of IBD, as well as each type of IBD with C. difficile colitis. Lastly, each type of hospitalization rate was also strongly correlated with each type of mortality rate. In general, hospitalization and mortality associated with IBD tended to be frequent in many of the northern states and infrequent in the Southwest and several southern states. Conclusions: The similarity in the geographic distribution of the 3 diseases could indicate the influence of C. difficile colitis in shaping the geographic patterns of IBD. It could also indicate that shared environmental risk factors influence the occurrence of IBD, as well as C. difficile colitis. (Inflamm Bowel Dis 2010) [source]

Asthma Hospitalization Rates Among Children, and School Building Conditions, by New York State School Districts, 1991-2001

JOURNAL OF SCHOOL HEALTH, Issue 8 2006
Erin Belanger
This study examined patterns of asthma hospitalization and possible factors contributing to asthma hospitalizations, including sociodemographics and school environmental factors, among school-age children (5-18 years) in New York State (NYS) over an 11-year period (1991-2001). Asthma hospitalization data from the Statewide Planning and Research Cooperative System and the 1990 and 2000 census population files were geocoded into NYS school districts statewide, and school district asthma hospitalization rates were then calculated. Building Condition Survey for each school was then utilized to create summary measures of school building conditions for each school district. Hospitalization rates were linked to district school building conditions by using logistic regression analysis that controlled for poverty. Calculation of time trends revealed overall declines in asthma rates among school-age children for NYS from 1991 to 2001. This general decline was found in each sociodemographic group. The mean rate for NYS from 1991 to 2001 was 27/10,000. Poorly rated building systems that were significantly associated with increased school district asthma hospitalization rates were roofing (odds ratio [OR] = 1.76; 95% confidence interval [CI95] = 1.13-2.74), windows (OR = 1.66; CI95= 1.08-2.54), exterior walls (OR = 2.24; CI95= 1.31-3.83), floor finishes (OR = 1.75; CI95= 1.14-2.69), and boiler/furnace (OR = 1.71; CI95= 1.99-2.94). This does not indicate a definite link between these systems and asthma hospitalizations since the available building system information is very general and crude.

Nationwide hospitalization costs of skin melanoma and non-melanoma skin cancer in Germany

JOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 1 2008
A Stang
Abstract Introduction, Non-melanoma skin cancer (NMSC), in contrast to skin melanoma (MEL), is considered a negligible health problem because mortality of NMSC is low. The aim of this study was to provide insights into the burden of NMSC and MEL by analysing nationwide skin cancer hospitalization data and data from a dermatologist panel of Germany. We wanted to estimate hospitalization costs due to skin cancer in Germany. Material and methods, We analysed the most recent nationwide hospitalization data from 2003 and estimated hospitalization costs due to MEL and NMSC. We estimated the annual number of private dermatologist practice visits in Germany due to skin cancer. Results, In 2003, 20 455 melanoma-related and 41 929 NMSC-related hospitalizations occurred in Germany. Age-standardized hospitalization rates for NMSC were 2.5-fold and 1.8-fold higher among men and women than the rates for MEL, respectively. The age-specific proportions of hospitalizations for NMSC in relation to all cancer-related hospitalizations increased within the age range of 65 years and more. Among people aged 90 years and more, 14% of all cancer-related hospitalizations were due to NMSC. Estimated annual hospitalization costs for MEL were ,50 to 60 million, and those for NMSC were ,105 to 130 million. The estimated number of private dermatologist practice visits in Germany 2003 is considerably higher for NMSC than MEL Conclusions, Analyses of hospitalizations data and data from private dermatologists give NMSC higher public health relevance than can be obtained from consideration of death statistics.

Systematic review: the global incidence and prevalence of peptic ulcer disease

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 9 2009
J. J. Y. SUNG
Summary Background, Peptic ulcer disease (PUD) is most commonly associated with Helicobacter pylori infection and the use of acetylsalicylic acid (ASA) and nonsteroidal anti-inflammatory drugs (NSAIDs). The management of H. pylori infection has improved radically in recent years; however, the prescription of ASA and NSAIDs has increased over the same period. Aim, To evaluate the current global incidence and prevalence of PUD by systematic review of the literature published over the last decade. Methods, Systematic searches of PubMed, EMBASE and the Cochrane library. Results, The annual incidence rates of PUD were 0.10,0.19% for physician-diagnosed PUD and 0.03,0.17% when based on hospitalization data. The 1-year prevalence based on physician diagnosis was 0.12,1.50% and that based on hospitalization data was 0.10,0.19%. The majority of studies reported a decrease in the incidence or prevalence of PUD over time. Conclusions, Peptic ulcer disease remains a common condition, although reported incidence and prevalence are decreasing. This decrease may be due to a decrease in H. pylori -associated PUD. [source]

The burden of lung disease in Hong Kong: A report from the Hong Kong Thoracic Society

RESPIROLOGY, Issue 2008
Moira CHAN-YEUNG
Background and objective: The burden of lung disease in Hong Kong is not known. This study determined the mortality and hospitalization rates of respiratory diseases in Hong Kong in 2005, their trend in the past decade and their incidence/prevalence. Methods: Mortality data were obtained from the Department of Health and hospitalization data from the Hospital Authority, Hong Kong. Incidence/prevalence data were obtained from local registries or local studies. Trends of mortality and hospitalization rates of various respiratory diseases from 1997 and 2005 were calculated after age standardization and were tested for significance using negative binomial regression analysis. Age standardized mortality rates in Hong Kong were compared with those of the UK and globally. Results: Respiratory disease was the most common cause of mortality and hospitalization in Hong Kong in 2005. Globally and in the UK, cardiovascular disease ranked first in mortality. Respiratory infections ranked first in respiratory mortality, followed by respiratory tract cancer and chronic obstructive lung disease. Respiratory infections also ranked first followed by chronic obstructive lung disease in the utilization of respiratory inpatient bed-days. While mortality rates from all respiratory diseases decreased in the past decade, hospitalization rates remained unchanged. Unlike other respiratory diseases, mortality from respiratory infections have increased since 2001. Smoking is the most important risk factor in non-communicable respiratory diseases. Conclusions: Respiratory disease is responsible for the highest health-care burden locally. Increased efforts in improving management and prevention of these diseases, including tobacco control, improving air quality and vaccination against influenza and pneumococci, are necessary.

Semiparametric Analysis for Recurrent Event Data with Time-Dependent Covariates and Informative Censoring

BIOMETRICS, Issue 1 2010
C.-Y. Huang
Summary Recurrent event data analyses are usually conducted under the assumption that the censoring time is independent of the recurrent event process. In many applications the censoring time can be informative about the underlying recurrent event process, especially in situations where a correlated failure event could potentially terminate the observation of recurrent events. In this article, we consider a semiparametric model of recurrent event data that allows correlations between censoring times and recurrent event process via frailty. This flexible framework incorporates both time-dependent and time-independent covariates in the formulation, while leaving the distributions of frailty and censoring times unspecified. We propose a novel semiparametric inference procedure that depends on neither the frailty nor the censoring time distribution. Large sample properties of the regression parameter estimates and the estimated baseline cumulative intensity functions are studied. Numerical studies demonstrate that the proposed methodology performs well for realistic sample sizes. An analysis of hospitalization data for patients in an AIDS cohort study is presented to illustrate the proposed method. [source]
