Mortality outcomes in pediatric rheumatology in the US

ARTHRITIS & RHEUMATISM, Issue 2 2010
Philip J. Hashkes
Objective To describe mortality rates, causes of death, and potential mortality risk factors in pediatric rheumatic diseases in the US. Methods We used the Indianapolis Pediatric Rheumatology Disease Registry, which includes 49,023 patients from 62 centers who were newly diagnosed between 1992 and 2001. Identifiers were matched with the Social Security Death Index censored for March 2005. Deaths were confirmed by death certificates, referring physicians, and medical records. Causes of death were derived by chart review or from the death certificate. Standardized mortality ratios (SMRs) and 95% confidence intervals (95% CIs) were determined. Results After excluding patients with malignancy, 110 deaths among 48,885 patients (0.23%) were confirmed. Patients had been followed up for a mean ± SD of 7.9 ± 2.7 years. The SMR of the entire cohort was significantly decreased (0.65 [95% CI 0.53,0.78]), with differences in patients followed up for ,9 years. The SMR was significantly greater for systemic lupus erythematosus (3.06 [95% CI 1.78,4.90]) and dermatomyositis (2.64 [95% CI 0.86,6.17]) but not for systemic juvenile rheumatoid arthritis (1.8 [95% CI 0.66,3.92]). The SMR was significantly decreased in pain syndromes (0.41 [95% CI 0.21,0.72]). Causes of death were related to the rheumatic diagnosis (including complications) in 39 patients (35%), treatment complications in 11 (10%), non-natural causes in 25 (23%), background disease in 23 (21%), and were unknown in 12 patients (11%). Rheumatic diagnoses, age at diagnosis, sex, and early use of systemic steroids and methotrexate were significantly associated with the risk of death. Conclusion Our findings indicate that the overall mortality rate for pediatric rheumatic diseases was not increased. Even for the diseases and conditions associated with increased mortality, mortality rates were significantly lower than those reported in previous studies. [source]


Age, period and cohort influences on beer, wine and spirits consumption trends in the US National Alcohol Surveys

ADDICTION, Issue 9 2004
William C. Kerr
ABSTRACT Aims To estimate the separate influences of age, period and cohort on the consumption of beer wine and spirits in the United States. Design Linear age,period,cohort models controlling for demographic change with extensive specification testing. Setting US general population 1979,2000. Measurements Monthly average of past-year consumption of beer, wine and spirits in five National Alcohol Surveys. Findings The strongest cohort effects are found for spirits; cohorts born before 1940 are found to have significantly higher consumption than those born after 1946, with especially high spirits consumption for men in the pre-1930s cohorts. Significant cohort effects are also found for beer with elevated consumption in the 1946,65 cohorts for men but in the pre-1940 cohorts for women. Significant negative effects of age are found for beer and spirits consumption, although not for wine. Significant period effects are found for men's beer and wine consumption and for women's spirits consumption. Increased educational attainment in the population over time is associated with reduced beer consumption and increased wine consumption. Conclusions Changing cohort demographics are found to have significant effects on beverage-specific consumption, indicating the importance of controlling for these effects in the evaluation of alcohol policy effectiveness and the potential for substantial improvement in the forecasting of future beverage-specific consumption trends, alcohol dependence treatment demand and morbidity and mortality outcomes.

Anemia and its impact on function in nursing home residents: What do we know?

JOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 1 2010
CRNP Assistant Professor, Valerie K. Sabol PhD
Purpose: To provide the advanced practice nurse (APN) information on the prevalence and causes of anemia in elderly nursing home (NH) residents, in order to affect diagnostic and management strategies that may help improve physical function and mobility outcomes. Data Sources: Literature review of current peer-reviewed research articles. Conclusions: In the United States, the prevalence of anemia increases with advancing age, and are reported to be much higher among older NH residents than among community-dwelling older adults. Causes of anemia among the elderly are often multifactorial. Older individuals with anemia, including mild anemia and even low normal level, have demonstrated lower muscle strength, physical function, mobility, and increased morbidity and mortality outcomes. Implications for Practice: Given the potentially significant relationship between anemia and physical performance outcomes among NH residents, gaining a better understanding will help guide future evidence-based care by allowing the APN an opportunity to tailor both medical and restorative care interventions. Because anemia is a potentially modifiable condition, intervention may preserve, limit, or reverse functional impairment and/or disablement, and allow for maximal functional independence. [source]


A Case-Control Follow-up Study for Disease-Specific Mortality

BIOMETRICS, Issue 1 2003
Marshall M. Joffe
Summary. Case-control studies often rely on subjects to report their own screening or exposure information; this information is often obtained from cases after the event of interest has occurred. This is problematic for mortality outcomes, because dead subjects cannot report the desired information. To avoid this problem, Weiss and Lazovich (1996, American Journal of Epidemiology143, 319,322) proposed obtaining exposure or screening information from potential cases, i.e., subjects diagnosed with disease, at the time of disease diagnosis, and also from a referent series. The design is best viewed as a new scheme for sampling from a cohort. I review estimation of the effects of time-varying screening or exposure in cohort studies, using a new factorization. I then show how this factorization, together with ignorability assumptions, allows valid estimation from these new designs. Even when the sampling fraction of nondiseased subjects is unknown, causal risk ratios are estimable if diagnosis is rare in the cohort. I illustrate and compare conventional and new methods with data from the Health Insurance Plan study. [source]


Noninvasive Ventilation Outcomes in 2,430 Acute Decompensated Heart Failure Patients: An ADHERE Registry Analysis

ACADEMIC EMERGENCY MEDICINE, Issue 4 2008
Thomas A. Tallman DO
Abstract Objectives:, Continuous or bilevel positive airway pressure ventilation, called noninvasive ventilation (NIV), is a controversial therapy for acute decompensated heart failure (ADHF). While NIV is considered safe and effective in patients with chronic obstructive pulmonary disease (COPD), clinical trial data that have addressed safety in ADHF patients are limited, with some suggestion of increased mortality. The objective of this study was to assess mortality outcomes associated with NIV and to determine if a failed trial of NIV followed by endotracheal intubation (ETI) (NIV failure) is associated with worse outcomes, compared to immediate ETI. Methods:, This was a retrospective analysis of the Acute Decompensated Heart Failure National Registry (ADHERE), which enrolls patients with treatment for, or with a primary discharge diagnosis of, ADHF. The authors compared characteristics and outcomes in four groups: no ventilation, NIV success, NIV failure, and ETI. One-way analysis of variance or Wilcoxon testing was performed for continuous data, and chi-square tests were used for categorical data. In addition, multivariable logistic regression was used to adjust mortality comparisons for risk factors. Results:, Entry criteria were met by 37,372 patients, of which 2,430 had ventilation assistance. Of the ventilation group, 1,688 (69.5%) were deemed NIV success, 72 (3.0%) were NIV failures, and 670 (27.6%) required ETI. The NIV failure group had the lowest O2 saturation (SaO2) (84 ± 16%), compared to either NIV success (89.6 ± 10%) or ETI (88 ± 13%; p = 0.017). ETI patients were more likely to receive vasoactive medications (p < 0.001) than the NIV success cohort. When comparing NIV failures to ETI, there were no differences in treatment during hospitalization (p > 0.05); other than that the NIV failure group more often received vasodilators (68.1% vs. 54.3%; p = 0.026). In-hospital mortality was 7.9% with NIV, 13.9% with NIV failure, and 15.4% with ETI. After risk adjustment, the mortality odds ratio for NIV failure versus ETI increased to 1.43, although this endpoint was not statistically significant. Conclusions:, In this analysis of ADHF patients receiving NIV to date, patients placed on NIV for ADHF fared better than patients requiring immediate ETI. Patients who failed NIV and required ETI still experienced lower mortality than those initially placed on ETI. Thus, while the ETI group may be more severely ill, starting therapy with NIV instead of immediate ETI will likely not harm the patient. When ETI is required, mortality and length of stay may be adversely affected. Since a successful trial of NIV is associated with improved outcomes in patients with ADHF, application of this therapy may be a reasonable treatment option. [source]
