Abstract
BACKGROUND Given the rising media attention regarding various adverse conditions attributed to breast implants, the authors examined the association between breast implantation and the risk of being diagnosed with connective tissue diseases, allergic reactions, and nonspecific constitutional complaints in a cohort study with longitudinal follow-up. METHODS Women enrolled in a regional military health care system between 2003 and 2012 were evaluated in this retrospective cohort study. A propensity score was generated to match women who underwent breast implantation with women who did not undergo breast implantation. The propensity score included age, social history, health care use, comorbidities, and medication use. Outcomes assessed included International Classification of Diseases, Ninth Revision, diagnoses codes for (1) nonspecific constitutional symptoms, (2) nonspecific cardiac conditions, (3) rheumatoid arthritis and systemic lupus erythematosus, (4) other connective tissue diseases, and (5) allergic reactions. RESULTS Of 22,063 women included in the study (513 breast implants and 21,550 controls), we propensity score-matched 452 breast implant recipients with 452 nonrecipients. Odds ratios and 95 percent confidence intervals in breast implant recipients compared to nonrecipients were similar, including nonspecific constitutional symptoms (OR, 0.77; 95 percent CI, 0.53 to 1.13), nonspecific cardiac conditions (OR, 0.97; 95 percent CI, 0.69 to 1.37), rheumatoid arthritis and systemic lupus erythematosus (OR, 0.66; 95 percent CI, 0.33 to 1.31), other connective tissue diseases (OR, 1.02; 95 percent CI, 0.78 to 1.32), and allergic reactions (OR, 1.18; 95 percent CI, 0.84 to 1.66). CONCLUSIONS Women with breast implants did not have an increased likelihood of being diagnosed with nonspecific constitutional symptoms, connective tissue disorders, and/or allergic reaction conditions. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Statins and New-Onset Diabetes Mellitus and Diabetic Complications: A Retrospective Cohort Study of US Healthy Adults. J Gen Intern Med 2015; 30:1599-610. [PMID: 25917657 PMCID: PMC4617949 DOI: 10.1007/s11606-015-3335-1] [Citation(s) in RCA: 45] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2014] [Revised: 02/26/2015] [Accepted: 03/27/2015] [Indexed: 12/12/2022]
Abstract
BACKGROUND Statin use is associated with increased incidence of diabetes and possibly with increased body weight and reduced exercise capacity. Data on the long-term effects of these associations in healthy adults, however, are very limited. In addition, the relationship between these effects and diabetic complications has not been adequately studied. OBJECTIVE To examine the association between statin use and new-onset diabetes, diabetic complications, and overweight/obesity in a cohort of healthy adults. RESEARCH DESIGN This was a retrospective cohort study. PARTICIPANTS Subjects were Tricare beneficiaries who were evaluated between October 1, 2003 and March 1, 2012. Patients were divided into statin users and nonusers. INTERVENTION We excluded patients who, at baseline, had a preexisting disease indicative of cardiovascular diseases, any positive element of the Charlson comorbidity index (including diabetes mellitus), or life-limiting chronic diseases. Using 42 baseline characteristics, we generated a propensity score to match statin users and nonusers. MAIN MEASURES Outcomes assessed included new-onset diabetes, diabetic complications, and overweight/obesity. KEY RESULTS A total of 25,970 patients (3982 statin users and 21,988 nonusers) were identified as healthy adults at baseline. Of these, 3351 statins users and 3351 nonusers were propensity score-matched. Statin users had higher odds of new-onset diabetes (odds ratio [OR] 1.87; 95 % confidence interval [95 % CI] 1.67-2.01), diabetes with complications (OR 2.50; 95 % CI 1.88-3.32), and overweight/obesity (OR 1.14; 95 % CI 1.04-1.25). Secondary and sensitivity analyses demonstrated similar findings. CONCLUSIONS Diabetes, diabetic complications, and overweight/obesity were more commonly diagnosed among statin-users than similar nonusers in a healthy cohort of adults. This study demonstrates that short-term clinical trials might not fully describe the risk/benefit of long-term statin use for primary prevention.

Abstract
OBJECTIVE Data on the burden of gastrointestinal diseases are incomplete, particularly in Southern European countries. The aim of this study was to estimate the burden of digestive diseases in Portugal. PATIENTS AND METHODS This was a retrospective observational study based on the national hospitalizations database that identified all consecutive episodes with a first diagnosis of a digestive disease between 2000 and 2010 using ICD-9-CM codes. Comparative analyses were carried out to assess hospitalization trends of major indicators over time and across regions. RESULTS More than 75,000 deaths attributable to digestive diseases were observed, representing 16% of the overall in-hospital mortality. Over half of these (59%) were premature deaths (in patients <75 years of age). Biliary tract disease was the most common digestive disorder leading to hospitalization (249,817 episodes, 5210 episodes of acute stone-related cholecystitis in 2010, with an 11% increase compared with 2000). Gastric cancer was responsible for the highest number of in-hospital deaths (10,278) and alcohol-related liver disorders accounted for the highest in-hospital premature deaths (7572). Both costs and the in-hospital mortality rate for major digestive diseases showed a significant positive relation with progression of time (β=0.195, P<0.001); however, when adjusted for age, this was not significant. Significant positive associations were found between age and in-hospital mortality (odds ratio=1.032, P<0.001) and between costs and in-hospital mortality (odds ratio=1.054, P<0.001). CONCLUSION In Portugal, digestive diseases represent a major burden, with evidence of an increasing trend. An ageing population contributes strongly towards this increase, placing further demands on healthcare organizations. Diseases such as gastric cancer, biliary tract disease and alcohol-related liver disorders may require particular attention.

Abstract
Background/Aims Management of irritable bowel syndrome (IBS) imposes a heavy economic burden. This study was to estimate the epidemiologic features of IBS and to report the IBS burden for the first time in the Korean population. Methods A cross-sectional study was conducted using the National Health Insurance (NHI) system database, which covers the entire population of Korea. IBS was defined as diagnostic code −10 in adults with any outpatient clinic visits or hospitalization related to IBS. We excluded diseases that mimic IBS symptoms. Results A total of 2.42 million (58.2% female) individuals were identified as patients with IBS, yielding an age- and gender-adjusted prevalence of 5.1% in males and 6.9% in females. The prevalence of IBS increased proportionally with age, with higher medical costs in middle-aged patients. Outpatient clinics were visited by 98.6% of IBS patients, and 1.9% were treated upon admission. Of these patients, 87.6% were given a prescription. Co-morbidities that commonly accompanied IBS included upper gastrointestinal (36.1%), respiratory (12.3%), musculoskeletal (8.0%) disease, somatoform (4.3%) and depression/anxiety disorders (3.1%). The NHI costs of IBS, which include the NHI covered cost and beneficiary copayment charges, were estimated to be 155 million USD, which accounts for 0.46% of the total NHI costs for the entire Korean population. Conclusions According to the Korean national claims database, about 6% of the Korean population seeks medical care for IBS at least once per year. This high prevalence places a large economic burden on the Korean healthcare system, accounting for 0.46% of overall national medical expenditure.

Abstract
OBJECTIVES To quantify the annual excess direct medical costs of vision impairment from the perspective of the Bureau of National Health Insurance in Taiwan and to examine whether the costs vary by severity and duration of vision impairment. METHODS A retrospective matched cohort analysis was conducted by using data from the Longitudinal Health Insurance Databases between January 1, 2000, and December 31, 2008. All patients newly diagnosed with vision impairment were categorized as having moderate vision loss, severe vision loss, or blindness. Each patient with vision impairment was matched to one randomly selected patient with normal vision by age (±1 year) and sex. At each level of vision impairment, generalized linear models were used to quantify the total annual excess costs and component costs incurred in the first and second years. RESULTS Vision impairment was associated with significantly higher crude excess medical costs. At each level of vision impairment, the total crude medical costs were attributable to different resource utilization and dominated by non-eye-related medical care. After adjusting for covariates, the first-year annual excess costs increased with escalating severity of vision impairment: New Taiwan (NT) $9894 for moderate vision loss, NT $22,760 for severe vision loss, and NT $52,687 for blindness. Similarly, the second-year adjusted costs were estimated as NT $3477, NT $19,532, and NT $28,272 for moderate vision loss, severe vision loss, and blindness, respectively. CONCLUSIONS Consistent with Western countries, vision impairment is associated with significantly increased health care costs in Taiwan. The excess costs seem to increase with severity of vision impairment and decrease in the second year.

Abstract
BACKGROUND/AIMS Gastrointestinal (GI) diseases impose a heavy economic burden. We aimed to provide the first report on the health care utilization and costs of GI diseases in Korea. METHODS We collected the data from all insurance claims database of National Health Insurance Corporation in Korea and the cause of death database in 2007 of Korea National Statistical Office. We compiled information about all digestive disease as a primary diagnosis on clinic visits, hospitalization, and cause of death from these databases. RESULTS Seventeen million people (35.6%) had a diagnosis of GI diseases during the year 2007. Among them, the proportion of patients with upper GI diseases was prevalent in 54.9% (9.5 million patients/year). The 1/4 patients in out-patients clinic had any one of gastroesophageal reflux disease, irritable bowel syndrome and constipation. Thirteen percent of the total direct cost in 2007 was attributed to all GI diseases, which was 3,649 billion won (0.4% of GDP). The patients with hospitalization occupied by 5% of all patients with GI diseases, however, attributed to 58.9% of GI-related direct costs. GI malignancy was the major cause of medical expenses in hospitalization. Stomach cancer continues to be the leading cause of GI-related death in Korea. CONCLUSIONS GI diseases causes a heavy socioeconomic burden with high morbidity of functional GI disorders in outpatients care and high mortality of GI malignancy in inpatient care. This report highlights the healthcare utilization burden of GI diseases for researchers and public health policy maker to create new directions of integrated researches and health care plan.

Abstract
BACKGROUND We used the insurance claims of a representative cohort to quantify the patterns of ambulatory care visits, especially the doctor-shopping phenomenon, in Taiwan. METHODS The ambulatory visit files of the 200,000-person cohort datasets from the National Health Insurance Research Database in 2002 were analyzed. Only a visit with physician consultation would be considered. We computed the visit patterns both by visit count and by patient count. RESULTS In 2002, there were 182,474 eligible people with 2,443,003 physician consultations. During the year, 87.4% of the cohort had visited physician clinics and 57.5% had visited hospital-based outpatient or emergency departments. On average, a person had 13.4 physician consultations and consulted 3.4 specialties, 5.2 physicians, and 3.9 healthcare facilities in a year. In 2002, 17.3% of the cohort had ever visited different healthcare facilities on the same day; 23.5% had ever visited physicians of the same specialty at different healthcare facilities within 7 days and the percentage of second visits was 3.8% of all visits. Besides, 7.6% of the cohort had visited two or more specialties at the same facility on the same day, and such visits make up 2.5% of all visits. CONCLUSION The people in Taiwan did visit the physicians and outpatient departments frequently. Many patients not only consulted several physicians of different specialties and at different healthcare facilities during the year, but also switched the physicians and facilities quickly. An effective referral system with efficient data exchange between facilities might be the solution.
