Effects Of Cost Sharing On Seeking Care For Serious And Minor Symptoms. Results Of A Randomized Controlled Trial, Martin Shapiro, John Ware, Cathy Sherbourne

Martin Shapiro

To estimate the effect of cost sharing on seeking care for serious and minor symptoms, we analyzed data for 3539 persons aged 17 to 61 from the Rand Health Insurance Experiment. Participants were randomly assigned to a free-care group or to insurance plans requiring them to pay part of the costs (cost-sharing group). Annual surveys were administered to determine if participants had serious and minor symptoms during the preceding month and whether they saw a physician. Serious symptoms were judged by a panel of physicians to warrant care in most instances; minor symptoms were judged neither to be severe nor …

Knowledge, Attitudes, Beliefs And Behaviors (Kabb) Of Diabetes Among Afro-Caribbeans Near Brooklyn, New York, Sophia Allen

Sophia I. Allen, Ph.D.

Diabetes is an epidemic in the U.S. that unduly affects minority groups. African Americans are more than two times as likely to die from diabetes than whites. Literature previously established that some population groups have a negative perception toward medical professionals and visiting a doctor's office and/or hospital when a health problem occurs. In New York City, where a large group of Afro-Caribbeans live, diabetes prevalence more than doubled over the past 10 years with over half a million adults diagnosed. Due to a gap in literature in the U.S. on type 2 diabetes among English-speaking Afro-Caribbeans, this study recruited …

The Statistics Of Sensitivity Analyses, Alexander R. Luedtke, Ivan Diaz, Mark J. Van Der Laan

Alex Luedtke

Suppose one wishes to estimate a causal parameter given a sample of observations. This requires making unidentifiable assumptions about an underlying causal mechanism. Sensitivity analyses help investigators understand what impact violations of these assumptions could have on the causal conclusions drawn from a study, though themselves rely on untestable (but hopefully more interpretable) assumptions. Díaz and van der Laan (2013) advocate the use of a sequence (or continuum) of interpretable untestable assumptions of increasing plausibility for the sensitivity analysis so that experts can have informed opinions about which are true. In this work, we argue that using appropriate statistical procedures …

Ideas For A Healthy Baby--Reducing Disparities In Use Of Publicly Reported Quality Data: Study Protocol For A Randomized Controlled Trial, Sarah L. Goff, Penelope S. Pekow, Katharine O. White, Tara Lagu, Kathleen M. Mazor, Peter K. Lindenauer

Sarah L. Goff MD

BACKGROUND: Publicly reported performance on quality measures is intended to enable patients to make more informed choices. Despite the growing availability of these reports, patients' use remains limited and disparities exist. Low health literacy and numeracy are two barriers that may contribute to these disparities. Patient navigators have helped patients overcome barriers such as these in other areas, such as cancer care and may prove useful for overcoming barriers to using publicly reported quality data. METHODS/DESIGN: The goals of this study are: to determine the efficacy of a patient navigator intervention to assist low-income pregnant women in the use of …

Richard H. McManus

BACKGROUND: Limited contemporary data compare the clinical and psychosocial characteristics and acute management of patients hospitalized with an initial vs a recurrent episode of acute coronary disease. We describe these factors in a cohort of patients recruited from 6 hospitals in Massachusetts and Georgia after an acute coronary syndrome. MATERIALS AND METHODS: We performed structured baseline in-person interviews and medical record abstractions for 2174 eligible and consenting patients surviving hospitalization for an acute coronary syndrome between April 2011 and May 2013. RESULTS: The average patient age was 61 years, 64% were men, and 47% had a high school education or …

Use Of Medications Of Questionable Benefit In Advanced Dementia, Jennifer Tjia, Becky Briesacher, Daniel Peterson, Qin Liu, Susan Andrade, Susan Mitchell

Jennifer Tjia

IMPORTANCE: Advanced dementia is characterized by severe cognitive impairment and complete functional dependence. Patients' goals of care should guide the prescribing of medication during such terminal illness. Medications that do not promote the primary goal of care should be minimized. OBJECTIVES: To estimate the prevalence of medications with questionable benefit used by nursing home residents with advanced dementia, identify resident- and facility-level characteristics associated with such use, and estimate associated medication expenditures. DESIGN, SETTING, AND PARTICIPANTS: Cross-sectional study of medication use by nursing home residents with advanced dementia using a nationwide long-term care pharmacy database linked to the Minimum Data …

The Spatial Dynamics Of Dengue Virus In Kamphaeng Phet, Thailand, Piraya Bhoomiboonchoo, Robert V. Gibbons, Angkana Huang, In-Kyu Yoon, Darunee Buddhari, Ananda Nisalak, Natkamol Chansatiporn, Mathuros Thipayamongkolgul, Siripen Kalanarooj, Timothy Endy, Alan L. Rothman, Anon Srikiatkhachorn, Sharone Green, Mammen P. Mammen, Derek A. Cummings, Henrik Salje

Sharone Green

BACKGROUND: Dengue is endemic to the rural province of Kamphaeng Phet, Northern Thailand. A decade of prospective cohort studies has provided important insights into the dengue viruses and their generated disease. However, as elsewhere, spatial dynamics of the pathogen remain poorly understood. In particular, the spatial scale of transmission and the scale of clustering are poorly characterized. This information is critical for effective deployment of spatially targeted interventions and for understanding the mechanisms that drive the dispersal of the virus.

METHODOLOGY/PRINCIPAL FINDINGS: We geocoded the home locations of 4,768 confirmed dengue cases admitted to the main hospital in Kamphaeng Phet …

What Factors Predict Outcome At Relapse After Previous Esophagectomy And Adjuvant Therapy In High-Risk Esophageal Cancer?, Edward Yu, Patricia Tai, Richard Malthaner, Larry Stitt, George Rodrigues, Rashid Dar, Brian Yaremko, Jawaid Younus, Michael Sanatani, Mark Vincent, Brian Dingle, Dalilah Fortin, Richard Inculet

Richard A. Malthaner

Management of patients who have disease relapse after completion of surgery and adjuvant chemo-radiation (CRT) is controversial. Some oncologists would advocate intensive therapeutic intervention due to promising experience on treatment for recurrence disease while others would recommend palliative support due to the concerns for poor patient outcome post disease recurrence. In Addition, it is not clear if patient outcome is improved post adjuvant CRT when patients at risk have resection margin involvement and if time interval to recurrence can affect patient survival post relapse. The present study was conducted to determine what factors will affect patient outcome at relapse after …

Post-Operative Extended Volume External Beam Radiation Therapy Is Safe For High Risk Esophageal Cancer Patients, Edward Yu, Patricia Tai, Jawaid Younus, Richard Malthaner, Larry Stitt, Pauline Truong, George Rodrigues, Robert Ash, Rashid Dar, Anna Tomiak, Mark Vincent, Walter Kocha, Brian Dingle, Richard Inculet

Richard A. Malthaner

Post-operative radiation therapy (RT) (1) and post-operative chemoradiation (2) have been used for esophageal cancer patients deemed high risk for recurrence after esophagectomy. Defining opitmal RT target volume after esophagectomy is difficult due to significant changes in patient anatomy and function. Some radiationon cologists advocated the inclusion of the anastomotic site within the irradiation volume due to concerns for potential increased relapse risk, while others did not subscribe to this practice due to concerns for increased treatment related toxicity. We have previously reported patient outcome benefit using extended volume RT In management with high risk esophageal cancer patients underwent esopagectomy(3). …

OBJECTIVE: To assess the impact of extended field irradiation with anastomotic coverage on local recurrence in high risk resected esophageal cancerpatients. METHODS: From 1989-1999, high risk resected esophageal cancer cases receiving post-resection chemoradiation were reviewed. Adjuvant chemotherapy consisted of four cycles of fluorouracil-based regimens. Loco-regional irradiation with or without coverage of anastomotic site had radiation a dose range from 45-60 Gyat 1.8-2.0 Gy/fraction given with initial anterior-posterior/posterior-anterior arrangement with either extended (with anastomotic coverage), or small (without anastomotic coverage) field followed by oblique fields for boost. RESULTS: One hundred eighty-eight charts were reviewed. Seventy-two patients were eligible for post-resection chemoradiation. …

Cyclosporin Versus Tacrolimus For Liver Transplanted Patients, Elizabeth Haddad, Vivian Mcalister, Elizabeth Renouf, Richard Malthaner, Mette Kjaer, Lise Gluud

Richard A. Malthaner

A systematic review of randomized clinical trials (RCT) was undertaken to evaluate the beneficial and harmful effects of immunosuppression with cyclosporin versus tacrolimus for liver transplanted patients. MEDLINE, EMBASE, Cochrane Central and Hepato-Biliary Group Controlled Trials Registers were searched. Using fixed and random effects model, relative risk (RR), values <1 favoring>tacrolimus, with 95% confidence intervals (CI) were calculated. Of 717 potentially relevant references, 16 RCTs were eligible for inclusion. Mortality and graft loss at 1 year were significantly reduced in tacrolimus-treated recipients (Death: RR 0.85, 95% CI 0.73-0.99; graft loss: RR 0.73, 95% CI 0.61-0.86). Tacrolimus reduced the number of recipients …

The Role Of Radiation Therapy On Medically Inoperable Clinically Localized Non-Small Cell Lung Patients: London Regional Cancer Program (Lrcp) Clinical Experience, Michael Lee, Edward Yu, Robert Ash, Patricia Tai, Larry Stitt, George Rodrigues, Rashid Dar, Mark Vincent, Richard Inculet, Richard Malthaner

Richard A. Malthaner

Lung cancer is the most frequent cause of cancer death in both men and women in North America. In 2006, an estimated 22,700 Canadians will be diagnosed with lung cancer and 19,300 will die of it (Canadian Cancer Statistics 2006). Approximately 15-20% of NSCLC patients present with early or localized disease. Surgical resection of T1-2N0 NSCLC remains the treatment of choice for this population, and results in a 5-year survival rate of 50-70%. Patients deemed medically inoperable have been treated with non-surgical therapies, such as radiation therapy(RT), while some patients have simply been observed without any tumor therapy because of …

Subsets More Likely To Benefit From Surgery Or Prophylactic Cranial Irradiation After Chemoradiation For Localized Non-Small-Cell Lung Cancer, Bruce Keith, Mark Vincent, Larry Stitt, Anna Tomiak, Richard Malthaner, Edward Yu, Pauline Truong, Richard Inculet, Michael Lefcoe, A. Dar, Walter Kocha, Ian Craig

Richard A. Malthaner

After chemoradiation for localized non-small-cell lung cancer, surgery and prophylactic cranial irradiation (PCI) have been used as additional therapies. Less than a third of patients develop brain recurrences, or have local recurrence as their sole initial site of recurrence; these are groups that would benefit from PCI or surgery, respectively. Pretreatment identification of patients more likely to benefit from surgery or PCI would be useful. A retrospective analysis of 80 patients was performed to determine prognostic factors for such patterns of failure. Twenty-nine patients were subsequently selected for surgery in a nonrandomized manner. Seventeen patients had isolated local initial recurrence …
