A meta-analysis : obesity and colorectal cancer screening by Hong Zhang( )

1 edition published in 2007 in English and held by 3 WorldCat member libraries worldwide

Of cancer death, colorectal cancer death ranks second in the United States. Obesity is an important risk factor for colorectal cancer (1). Early detection of colorectal cancer when it is localized can effectively reduce mortality of colorectal cancer and increase survival time of patients if they are treated. Also, previous studies showed that obese women were more likely to delay breast cancer screening and cervical cancer screening than normal weight women (2-5). However, results from prior studies demonstrating the relationship between obesity and colorectal cancer screening are not consistent. This research was done to conduct a meta-analysis of previous cross-sectional studies selected from the Medline database and to evaluate the association between obesity and colorectal cancer screening. While the odds ratio was not statistically different from one, the results from this meta-analysis under the random effects model showed that obese people are slightly less likely to have colorectal cancer screening compared to normal weight individuals (OR,0.93;95% CI 0.75-1.15). This meta-analysis was particularly sensitive to one individual study (6) and the effect of obesity on colorectal cancer screening was statistically significant (OR, 0.87; 95% CI, 0.81-0.92) after removing Heo's study. Further systematic studies focused on whether the effect of obesity on colorectal cancer screening is limited to women only are suggested

An assessment of the relationship between board composition and healthcare organization financial performance by Yingliu Gu( Book )

1 edition published in 2009 in English and held by 2 WorldCat member libraries worldwide

Previous empirical literature regarding the relationship between an organization's board of directors (or trustees) and its financial performance is ambiguous. In this study, I use secondary data reported to the Internal Revenue Service through form 990 tax filings from 2004 to 2006 to test three hypotheses. The sample was the largest 100 non-profit healthcare organizations in the United States. Various measures of board composition, such as board Size and number of medical doctors were used as independent variables in this study. Four measures of financial performance (i.e., Return on assets, operation margin, debt ratio and days of working capitals) are calculated from tax forms and used as dependent variables in the research. OLS regression and Pearson correlations were performed to test the association among these variables. Descriptive statistics was conducted in this study to analysis the changes of incoming rank and board size of those organizations. Results suggest a trend towards transformation of governance models from a "philanthropic" model to a more "corporate" model. Results also show that higher performing hospitals tended to have smaller boards and greater percentage of physician directors. Implications for the industry are provided, and a discussion of the overall distribution of these top 100 non-profit organizations' are also described in this study

Study design. A literature review was done to specify the demand model by identifying relevant predictors and indicators. CHIS 2005 data was utilized for demand estimation
Interim analysis of clinical trials : simulation studies of fractional Brownian motion by Jin Huang( Book )

1 edition published in 2009 in English and held by 2 WorldCat member libraries worldwide

Interim clinical trial monitoring procedures were motivated by ethical and economic considerations. Classical Brownian motion (Bm) techniques for statistical monitoring of clinical trials were widely used. Conditional power argument and alpha-spending function based boundary crossing probabilities are popular statistical hypothesis testing procedures under the assumption of Brownian motion. However, it is not rare that the assumptions of Brownian motion are only partially met for trial data. Therefore, I used a more generalized form of stochastic process, called fractional Brownian motion (fBm), to model the test statistics. Fractional Brownian motion does not hold Markov property and future observations depend not only on the present observations but also on the past ones. In this dissertation, we simulated a wide range of fBm data, e.g., H = 0.5 (that is, classical Bm) vs. 0.5 & lt; H & lt;1, with treatment effects vs. without treatment effects. Then the performance of conditional power and boundary-crossing based interim analyses were compared by assuming that the data follow Bm or fBm. Our simulation study suggested that the conditional power or boundaries under fBm assumptions are generally higher than those under Bm assumptions when H> 0.5 and also matches better with the empirical results

Quality in healthcare organizations : its meaning and measurement by Afsaneh Barzi( Book )

1 edition published in 2009 in English and held by 2 WorldCat member libraries worldwide

This dissertation explores two important aspects of quality in healthcare: its meaning and its measurement. For a better understanding of what quality means, the history of quality in the manufacturing and service industries is reviewed. Concepts that are similar are pointed out as are concepts that are different. The definition introduced by the Institute of Medicine (IOM) for quality in healthcare and the six IOM aims of safety, timeliness, patient-centeredness, effectiveness, efficiency, and equitableness for a high quality healthcare system are adopted. The current activities by various organizations that proclaim improvement in quality or measurement of quality as their goal are reviewed. This is followed by examining what is offered by these organizations in terms of how many of IOM aims they address
Changes in sexual behaviors associated with crack cocaine cessation among African Americans in Houston, Texas by Eric A Ratliff( Book )

1 edition published in 2011 in English and held by 2 WorldCat member libraries worldwide

Findings At the six-month follow-up interview, 21% of participants reported that they had not used crack in the previous 30 days. For women, crack cessation was significantly associated with having only one sex partner at follow-up; for men, crack cessation was significantly associated with being single, separated, or divorced at baseline, having only one sex partner at follow-up, and initiating protected sex by follow-up
Home care service utilization in British Columbia : substitute or complement to acute care? by Anne-Marie Broemeling( )

1 edition published in 1998 in English and held by 2 WorldCat member libraries worldwide

These results suggest that home care is currently used as a complement rather than a substitute for some acute health services. Organizational and resource issues may contribute to the longer stays by home care clients. Program planning and policies are required if home care is to provide an effective substitute for acute hospital days
The Local safety net, health insurance, preventable hospitalizations and costs : Harris County (Houston), Texas by Yu F Lee( )

1 edition published in 2008 in English and held by 2 WorldCat member libraries worldwide

The aim of this study was to examine the association between determinants of access to healthcare and preventable hospitalizations, based on Davidson et al.'s framework for evaluating the effects of individual and community determinants on access to healthcare. The study population consisted of the low income, non-elderly, hospitalized adults residing in Harris County, Texas in 2004. The objectives of this study were to examine the proportion of the variance in preventable hospitalizations at the ZIP-code level, to analyze the association between the proximity to the nearest safety net clinic and preventable hospitalizations, to examine how the safety net capacity relates to preventable hospitalizations, to compare the relative strength of the associations of health insurance and the proximity to the nearest safety net clinic with preventable hospitalizations, and to estimate and compare the costs of preventable hospitalizations in Harris County with the average cost in the literature. The data were collected from Texas Health Care Information Collection (2004), Census 2000, and Project Safety Net (2004). A total of 61,841 eligible individuals were included in the final data analysis. A random-intercept multi-level model was constructed with two different levels of data: the individual level and the ZIP-code level. The results of this study suggest that ZIP-code characteristics explain about two percent of the variance in preventable hospitalizations and safety net capacity was marginally significantly associated with preventable hospitalizations (p= 0.062). Proximity to the nearest safety net clinic was not related to preventable hospitalizations; however, health insurance was significantly associated with a decreased risk of preventable hospitalization. The average direct cost was $6,466 per preventable hospitalization, which is significantly different from reports in the literature
Costs and quality of medication reconciliation practice in primary care clinics by Grace M Kuo( Book )

1 edition published in 2011 in English and held by 2 WorldCat member libraries worldwide

Medication reconciliation, with the aim to resolve medication discrepancy, is one of the Joint Commission patient safety goals. Medication errors and adverse drug events that could result from medication discrepancy affect a large population. At least 1.5 million adverse drug events and $3.5 billion of financial burden yearly associated with medication errors could be prevented by interventions such as medication reconciliation. This research was conducted to answer the following research questions: (1a) What are the frequency range and type of measures used to report outpatient medication discrepancy? (1b) Which effective and efficient strategies for medication reconciliation in the outpatient setting have been reported? (2) What are the costs associated with medication reconciliation practice in primary care clinics? (3) What is the quality of medication reconciliation practice in primary care clinics? (4) Is medication reconciliation practice in primary care clinics cost-effective from the clinic perspective? Study designs used to answer these questions included a systematic review, cost analysis, quality assessments, and cost-effectiveness analysis. Data sources were published articles in the medical literature and data from a prospective workflow study, which included 150 patients and 1,238 medications. The systematic review confirmed that the prevalence of medication discrepancy was high in ambulatory care and higher in primary care settings. Effective strategies for medication reconciliation included the use of pharmacists, letters, a standardized practice approach, and partnership between providers and patients. Our cost analysis showed that costs associated with medication reconciliation practice were not substantially different between primary care clinics using or not using electronic medical records (EMR) ($0.95 per patient per medication in EMR clinics vs. $0.96 per patient per medication in non-EMR clinics, p=0.78). Even though medication reconciliation was frequently practiced (97-98%), the quality of such practice was poor (0-33% of process completeness measured by concordance of medication numbers and 29-33% of accuracy measured by concordance of medication names) and negatively (though not significantly) associated with medication regimen complexity. The incremental cost-effectiveness ratios for concordance of medication number per patient per medication and concordance of medication names per patient per medication were both 0.08, favoring EMR. Future studies including potential cost-savings from medication features of the EMR and potential benefits to minimize severity of harm to patients from medication discrepancy are warranted
Bayesian generalized linear models for meta-analysis of diagnostic tests by Yan Xing( Book )

1 edition published in 2008 in English and held by 2 WorldCat member libraries worldwide

With the recognition of the importance of evidence-based medicine, there is an emerging need for methods to systematically synthesize available data. Specifically, methods to provide accurate estimates of test characteristics for diagnostic tests are needed to help physicians make better clinical decisions. To provide more flexible approaches for meta-analysis of diagnostic tests, we developed three Bayesian generalized linear models. Two of these models, a bivariate normal and a binomial model, analyzed pairs of sensitivity and specificity values while incorporating the correlation between these two outcome variables. Noninformative independent uniform priors were used for the variance of sensitivity, specificity and correlation. We also applied an inverse Wishart prior to check the sensitivity of the results. The third model was a multinomial model where the test results were modeled as multinomial random variables. All three models can include specific imaging techniques as covariates in order to compare performance. Vague normal priors were assigned to the coefficients of the covariates. The computations were carried out using the 'Bayesian inference using Gibbs sampling' implementation of Markov chain Monte Carlo techniques. We investigated the properties of the three proposed models through extensive simulation studies. We also applied these models to a previously published meta-analysis dataset on cervical cancer as well as to an unpublished melanoma dataset. In general, our findings show that the point estimates of sensitivity and specificity were consistent among Bayesian and frequentist bivariate normal and binomial models. However, in the simulation studies, the estimates of the correlation coefficient from Bayesian bivariate models are not as good as those obtained from frequentist estimation regardless of which prior distribution was used for the covariance matrix. The Bayesian multinomial model consistently underestimated the sensitivity and specificity regardless of the sample size and correlation coefficient. In conclusion, the Bayesian bivariate binomial model provides the most flexible framework for future applications because of its following strengths: (1) it facilitates direct comparison between different tests; (2) it captures the variability in both sensitivity and specificity simultaneously as well as the intercorrelation between the two; and (3) it can be directly applied to sparse data without ad hoc correction
A model of factors determining levels of public support for health care policy in the United States by Carol A Galeener( )

1 edition published in 2004 in English and held by 2 WorldCat member libraries worldwide

Public preferences for policy are formed in a little-understood process that is not adequately described by traditional economic theory of choice. In this paper I suggest that U.S. aggregate support for health reform can be modeled as tradeoffs among a small number of behavioral values and the stage of policy development. The theory underlying the model is based on Samuelson, et al. 's (1986) work and Wilke's (1991) elaboration of it as the Greed/Efficiency/Fairness (GEF) hypothesis of motivation in the management of resource dilemmas, and behavioral economics informed by Kahneman and Thaler's prospect theory
Costs and outcomes of observation units in triaging non-specific chest pain patients after their Emergency Room visits by Ibrahim Mohammed Abbass( Book )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

Results : Over thirty-seven percent (37.3% (n = 5,890)) of the sample was admitted to inpatient care vs. 62.7% (n= 9,961) in observation units. Patients admitted to the inpatient units stayed longer (1.5 days for inpatient vs. 21 hours for observation units), had higher comorbidities, and incurred higher costs. More than one third of patients admitted in observation units (37.5%) stayed longer than 24 hours. Inpatient admission had a higher per-patient cost of $1,308 (95% CI, $1,206 - $1,411) compared to observation units. Patients in observation units also received more MPI (35.8%) and CT scans (13.2%) compared to 31.5% and 10.4% of patients admitted to inpatient units. When comparing the outcomes between the two groups, only 7,549 patients had one year continuous enrollment following the initial ER visits in which 65.7% of the sample (n = 4,962) were admitted to observation units versus 34.3%(n= 2,587) of patients who were admitted to inpatient units wards. After adjusting for baseline characteristics, no differences were detected in the one year chest pain/cardiovascular diseases related costs, primary or secondary outcomes between the two groups except for the revascularization rates. Patients admitted to observation units were 77% (95%CI = 1.23-2.55) more likely to have revascularization procedures compared to those admitted to inpatient care

Quality of care and its impact on clinical and economic outcome in patients hospitalized from chronic obstructive pulmonary disease (COPD) by Suthira Taychakhoonavudh( Book )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

Methods: We used a retrospective population-based cohort study using enrollment and claims data for population insured by Blue Cross Blue Shield of Texas (BCBSTX) from the year 2008 to 2011. All hospital admissions and ED visits for COPD were extracted. Patients were identified as a recipient of guideline recommended care if, within 30 days of discharge, they had at least one claim of prescription fills for any maintenance medications and had at least one follow up visit with a primary care physician or pulmonologist. Clinical and economic outcomes include (1) the presence of a subsequent COPD-related exacerbation requiring hospitalization or an ED visit and (2) the annual total health care spending were assessed for one year post-discharge. Generalized linear mixed models were used to determine the patient-level, provider-level, and area-level factors that are associated with the receipt of guideline recommended care. Outcomes were compared between cohorts who receive and did not receive guideline recommended care using probit regression model with instrumental variable and a generalized linear mixed model
Childhood cancer inpatient utilization : patterns, costs, associated factors, and time trends from 2003 to 2009 by Heidi Russell( Book )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

Methods: Using the 2003, 2006, and 2009 Kids Inpatient Databases, products of the Healthcare Costs and Utilization Project, I identified 331,307 admissions associated with a cancer diagnosis. These admissions were grouped by cancer diagnosis and reasons for admission. Admissions charges were converted to costs using the average hospital cost to charge ratio. Time trends in utilization were calculated using linear (continuous variable) or logistic (categorical variable) regressions. I fit a multi-level model clustered on the admitting hospital of the of cancer diagnosis, reasons for admission, socio-demographic and location of treatment on the log-transformed total admission cost. Clustering was accounted for with both clustered ordinary least squared and fixed effects models
Cost-effectiveness analysis of stereotactic body radiotherapy and radiofrequency ablation for medically inoperable liver metastases from colorectal cancer by Anna Likhacheva( Book )

1 edition published in 2012 in English and held by 1 WorldCat member library worldwide

This report describes the development of a Markov model for comparing percutaneous radiofrequency ablation (RFA) and stereotactic body radiation therapy (SBRT) in terms of their cost-utility in treating isolated liver metastases from colorectal cancer. The model is based on data from multiple retrospective and prospective studies, available data on different utility states associated with treatment and complications, as well as publicly available Medicare costs. The purpose of this report is to establish a well-justified model for clinical management decisions. In comparison with SBRT, RFA is the most cost-effective treatment for this patient population. From the societal perspective, SBRT may be an acceptable alternative with an ICER of $28,673/QALY
