Project description:Vaccine effectiveness is usually determined in randomized controlled trials (RCT) and if effective, additional information, e.g. on cost-effectiveness, is required to allow evidence-based decision making. A prerequisite for proper health economic modelling is the availability of good quality data on health care resources use, health outcomes and quality-of-life (QoL) data. The "Collecting health outcomes and economic data on hospitalized Community Acquired Pneumonia (CHO-CAP)--a prospective cohort study" is executed alongside the Community Acquired Pneumonia Immunization Trial with Adults (CAPiTA trial) to capture health outcomes and economic data of elderly hospitalized with CAP and matched controls without CAP.CAPiTA is a placebo-controlled double-blind RCT evaluating the effectiveness of a 13-valent conjugated pneumococcal vaccine in preventing vaccine-type pneumococcal CAP in 84,496 elderly in the Netherlands. Participants of CAPiTA, who consented and provided information on health status (EQ-5D) and socio-demographic background at the time of vaccination, constitute the source population of CHO-CAP and are eligible for the nested matched cohort study. CHO-CAP patients hospitalized with CAP form the "diseased" cohort and the "non-diseased" cohort consists of unaffected persons (i.e. no CAP). Observations in the diseased cohort and in matched controls from the non-diseased cohort are used to determine excess costs and QoL changes attributable to CAP.Based on an estimated 2,000 CAPiTA participants being hospitalized with CAP and an assumed CHO-CAP participation rate of 30% of all CAPiTA participants (±25,000), 600 CAP episodes are expected among CHO-CAP participants (the "diseased" cohort). For each patient with CAP, two non-diseased CHO-CAP subjects will be selected from the CHO-CAP cohort, with matching for age, gender and EQ-5D baseline-score. Data on healthcare and non-healthcare resources use, quality-of-life (using EQ-5D and SF-36 questionnaires) and selected health outcomes will be collected at 0, 1, 6 and 12 months after hospitalization for CAP.The CHO-CAP study was approved by the Central Committee on Research involving Human Subjects in the Netherlands.With an expected 600 CAP episodes this study will be one of the biggest prospectively studied cohorts of hospitalized elderly with CAP with regard to resources use and Qol data. Strengths of this study further include collection of out-of-pocket costs of patients and productivity losses of both patients and their caregivers and the follow-up period of up to one year post-discharge. This study is therefore expected to add more in-depth knowledge on the short and longer term outcomes of pneumonia in elderly.ClinicalTrials.gov, NCT00812084.

Project description:BackgroundSepsis is a major public health problem. Social factors may affect health behaviors, economic resources, and immune response, leading to hospitalization for infection. This study examines the association between marital status and sepsis incidence and outcomes in a population-based cohort.MethodsWe analyzed 1,113,581 hospitalizations in New Jersey in 2006. We estimated risk-adjusted incidence rate ratios (IRRs) for sepsis among divorced, widowed, legally separated, single, and married subjects using population data from the American Community Survey. We used multivariable logistic regression to estimate marital status-specific hospital mortality.ResultsWe identified 37,524 hospitalizations for sepsis, of which 40% were among married (14,924), 7% were among divorced (2,548), 26% were among widowed (9,934), 2% (763) were among legally separated, and 26% (9355) were among single subjects. The incidence of hospitalization for sepsis was 5.8 per 1,000 population. The age, sex, and race-adjusted IRR for hospitalization with sepsis was greatest for single (IRR = 3.47; 95% CI, 3.1, 3.9), widowed (IRR = 1.38; 95% CI, 1.2, 1.6), and legally separated (IRR = 1.46; 95% CI, 1.2, 1.8) subjects compared with married (referent). We observed that single men and women and divorced men had greater odds of in-hospital mortality compared with married men; widowed and legally separated men and all ever-married women had no excess mortality during hospitalization for sepsis.ConclusionsHospitalization for sepsis is more common among single, widowed, and legally separated individuals, independent of other demographic factors. Among patients hospitalized for sepsis, single and divorced men and single women experience greater hospital mortality, highlighting the need to characterize the potentially modifiable mechanisms linking marital status to its greater burden of critical illness.

Project description:BackgroundPrior studies have established those elderly patients with chronic obstructive pulmonary disease (COPD) are at elevated risk for developing influenza-associated complications such as hospitalization, intensive-care admission, and death. This study sought to determine whether influenza vaccination could improve survival among elderly patients with COPD.Materials/methodsThis study included Veterans (age ≥ 65 years) diagnosed with COPD that received care at the United States Veterans Health Administration (VHA) during four influenza seasons, from 2012-2013 to 2015-2016. We linked VHA electronic medical records and Medicare administrative files to Centers for Disease Control and Prevention National Death Index cause of death records as well as influenza surveillance data. A multivariable time-dependent Cox proportional hazards model was used to compare rates of mortality of recipients of influenza vaccination to those who did not have records of influenza vaccination. We estimated hazard ratios (HRs) adjusted for age, gender, race, socioeconomic status, comorbidities, and healthcare utilization.ResultsOver a span of four influenza seasons, we included 1,856,970 person-seasons of observation where 1,199,275 (65%) had a record of influenza vaccination and 657,695 (35%) did not have a record of influenza vaccination. After adjusting for comorbidities, demographic and socioeconomic characteristics, influenza vaccination was associated with reduced risk of death during the most severe periods of influenza seasons: 75% all-cause (HR = 0.25; 95% CI: 0.24-0.26), 76% respiratory causes (HR = 0.24; 95% CI: 0.21-0.26), and 82% pneumonia/influenza cause (HR = 0.18; 95% CI: 0.13-0.26). A significant part of the effect could be attributed to "healthy vaccinee" bias as reduced risk of mortality was also found during the periods when there was no influenza activity and before patients received vaccination: 30% all-cause (HR = 0.70; 95% CI: 0.65-0.75), 32% respiratory causes (HR = 0.68; 95% CI: 0.60-0.78), and 51% pneumonia/influenza cause (HR = 0.49; 95% CI: 0.31-0.78). However, as a falsification study, we found that influenza vaccination had no impact on hospitalization due to urinary tract infection (HR = 0.97; 95% CI: 0.80-1.18).ConclusionsAmong elderly patients with COPD, influenza vaccination was associated with reduced risk for all-cause and cause-specific mortality.

Project description:BackgroundRecent studies suggest that metformin use may be associated with improved infectious disease-related outcomes, whereas other papers suggest potentially worse outcomes in serious bacterial infections. Our purpose was to examine the association of prior outpatient prescription of metformin on 30- and 90-day mortality for older veterans with pre-existing diabetes hospitalized with pneumonia.MethodsWe conducted a retrospective cohort study using national Department of Veterans Affairs data of patients ≥65 years with a prior history of diabetes who were hospitalized with pneumonia over a 10-year period (fiscal years 2002-2012.) For our primary analysis, we created a propensity score and matched metformin users to nonusers 1:1.ResultsWe identified 34 759 patients who met the inclusion criteria, 20.3% of whom were prescribed metformin. Unadjusted 30-day mortality was 9.6% for those who received metformin versus 13.9% in nonusers (P < .003), and 90-day mortality was 15.8% for those who received metformin versus 23.0% for nonusers (P < .0001). For the propensity score model, we matched 6899 metformin users to 6899 nonusers. After propensity matching, both 30-day (relative risk [RR]: .86; 95% confidence interval [CI]: .78-.95) and 90-day (RR: .85; 95% CI: .79-.92) mortality was significantly lower for metformin users.ConclusionsPrior receipt of metformin was associated with significantly lower mortality after adjusting for potential confounders. Additional research is needed to examine the safety and potential benefits of metformin use in patients with respiratory infections.

Project description:BackgroundRates of all-cause and cause-specific mortality are higher among unmarried than married individuals. Cancer survival is also poorer in the unmarried population. Recently, some studies have found that the excess all-cause mortality of the unmarried has increased over time, and the same pattern has been shown for some specific causes of death. The objective of this study was to investigate whether there has been a similar change over time in marital status differences in cancer survival.MethodsDiscrete-time hazard regression models for cancer deaths among more than 440,000 women and men diagnosed with cancer 1970-2007 at age 30-89 were estimated, using register data encompassing the entire Norwegian population. More than 200,000 cancer deaths during over 2 million person-years of exposure were analyzed.ResultsThe excess mortality of the never-married compared to the married has increased steadily for men, in particular the elderly. Among elderly women, the excess mortality of the never-married compared to the married has increased, and there are indications of an increasing excess mortality of the widowed. The excess mortality of divorced men and women, however, has been stable.ConclusionsThere is no obvious explanation for the increasing disadvantage among the never-married. It could be due to a relatively poorer general health at time of diagnosis, either because of a more protective effect of partnership in a society that may have become less cohesive or because of more positive selection into marriage. Alternatively, it could be related to increasing differentials with respect to treatment. Today's complex cancer therapy regimens may be more difficult for never-married to follow, and health care interventions directed and adapted more specifically to the broad subgroup of never-married patients might be warranted.

Project description:BackgroundDespite limited and conflicting evidence, hydroxychloroquine, alone or in combination with azithromycin, is widely used in COVID-19 therapy.MethodsWe performed a retrospective study of electronic health records of patients hospitalized with confirmed SARS-CoV-2 infection in US Veterans Health Administration medical centers between March 9, 2020 and April 29, 2020. Patients hospitalized within 24 h of diagnosis were classified based on their exposure to hydroxychloroquine alone (HC) or with azithromycin (HC+AZ) or no HC as treatments. The primary outcomes were mortality and use of mechanical ventilation.FindingsA total of 807 patients were evaluated. Compared to the no HC group, after propensity score adjustment for clinical characteristics, the risk of death from any cause was higher in the HC group (adjusted hazard ratio [aHR], 1.83; 95% confidence interval [CI], 1.16-2.89; p = 0.009), but not in the HC+AZ group (aHR, 1.31; 95% CI, 0.80-2.15; p = 0.28). Both the propensity-score-adjusted risks of mechanical ventilation and death after mechanical ventilation were not significantly different in the HC group (aHR, 1.19; 95% CI, 0.78-1.82; p = 0.42 and aHR, 2.11; 95% CI, 0.96-4.62; p = 0.06, respectively) or in the HC+AZ group (aHR, 1.09; 95% CI, 0.72-1.66; p = 0.69 and aHR, 1.25; 95% CI, 0.59-2.68; p = 0.56, respectively) compared to the no HC group.ConclusionsAmong patients hospitalized with COVID-19, this retrospective study did not identify any significant reduction in mortality or in the need for mechanical ventilation with hydroxychloroquine treatment with or without azithromycin.FundingUniversity of Virginia Strategic Investment Fund.

Project description:The effect of marital status (MS) on survival varies according to cancer type and gender. There has been no report on the impact of MS on survival in male breast cancer (MBC). This study aims to determine the influence of MS on tumor stage at diagnosis and survival in MBC. Men with MBC ?18 years of age in the SEER database from 1990 to 2011 were included in the study. MS was classified as married and unmarried (including single, divorced, separated, widowed). Kaplan-Meier method was used to estimate the 5-year cancer-specific survival. Multivariate regression analyses were done to determine the effect of MS on presence of Stage IV disease at diagnosis and on cancer-specific mortality. The study included 3,761 men; 2,647 (70.4%) were married. Unmarried men were more often diagnosed with Stage IV MBC compared with married (10.7% vs. 5.5%, p < .001). Unmarried men (compared with married) were significantly less likely to undergo surgery (92.4% vs. 96.7%, p < .001). Overall unmarried males with Stages II, III, and IV MBC have significantly worse 5-year cancer-specific survival compared with married. On multivariate analysis, being unmarried was associated with increased hazard of death (HR = 1.43, p < .001) and increased likelihood of Stage IV disease at diagnosis ( OR = 1.96, p < .001). Unmarried males with breast cancer are at greater risk for Stage IV disease at diagnosis and poorer outcomes compared with married males.

Project description:ImportanceCancer is a leading cause of death among older people experiencing homelessness. However, the association of housing status with cancer outcomes is not well described.ObjectiveTo characterize the diagnosis, treatment, surgical outcomes, and mortality by housing status of patients who receive care from the US Department of Veterans Affairs (VA) health system for colorectal, breast, or lung cancer.Design, setting, and participantsThis retrospective cohort study identified all US veterans diagnosed with lung, colorectal, or breast cancer who received VA care between October 1, 2011, and September 30, 2020. Data analysis was performed from February 13 to May 9, 2023.ExposuresVeterans were classified as experiencing homelessness if they had any indicators of homelessness in outpatient visits, clinic reminders, diagnosis codes, or the Homeless Operations Management Evaluation System in the 12 months preceding diagnosis, with no subsequent evidence of stable housing.Main outcomes and measuresThe major outcomes, by cancer type, were as follows: (1) treatment course (eg, stage at diagnosis, time to treatment initiation), (2) surgical outcomes (eg, length of stay, major complications), (3) overall survival by cancer type, and (4) hazard ratios for overall survival in a model adjusted for age at diagnosis, sex, stage at diagnosis, race, ethnicity, marital status, facility location, and comorbidities.ResultsThis study included 109 485 veterans, with a mean (SD) age of 68.5 (9.7) years. Men comprised 92% of the cohort. In terms of race and ethnicity, 18% of veterans were Black, 4% were Hispanic, and 79% were White. A total of 68% of participants had lung cancer, 26% had colorectal cancer, and 6% had breast cancer. There were 5356 veterans (5%) experiencing homelessness, and these individuals more commonly presented with stage IV colorectal cancer than veterans with housing (22% vs 19%; P = .02). Patients experiencing homelessness had longer postoperative lengths of stay for all cancer types, but no differences in other treatment or surgical outcomes were observed. These patients also demonstrated higher rates of all-cause mortality 3 months after diagnosis for lung and colorectal cancers, with adjusted hazard ratios of 1.1 (95% CI, 1.1-1.2) and 1.3 (95% CI, 1.2-1.4) (both P < .001), respectively.Conclusions and relevanceIn this large retrospective study of US veterans with cancer, homelessness was associated with later stages at diagnosis for colorectal cancer. Differences in lung and colorectal cancer survival between patients with housing and those experiencing homelessness were present but smaller than observed in other settings. These findings suggest that there may be important systems in the VA that could inform policy to improve oncologic outcomes for patients experiencing homelessness.

Project description:BackgroundOlder adults from racial and ethnic minority groups are at higher risk for worse outcomes with COVID-19. This study sought to characterize the symptomatology of COVID-19 and the association of symptoms with all-cause in-hospital mortality and respiratory failure in a cohort of older, predominantly African American adults admitted to a tertiary hospital.MethodsA retrospective chart review of all hospitalized patients 65 and older with a positive SARS-CoV-2 test was conducted in a 953-bed academic, urban hospital. Measurements included demographics, symptoms, laboratory findings, and outcomes. The primary outcome was in-hospital mortality, and the secondary outcome was respiratory failure.ResultsA total of 134 patients with a mean age of 76.4 years were studied. Fifty-six percent were men and 90% were African American. Of these, 108 patients presented with typical symptoms, among whom 89.8% had co-existing geriatric syndromes. Only 10.2% presented with typical symptoms alone. The most common typical symptoms were fever (57%), shortness of breath (SOB) (51.2%), and cough (48.8%). Atypical symptoms were present in 68 (51%) patients, of whom 83.8% had co-existing typical symptoms and 76.5% had co-existing geriatric syndromes. Only 17.2% of patients presented with atypical symptoms alone. Atypical symptoms identified were anorexia (43%), dizziness (12.4%), and syncope (7.4%). Geriatric syndromes were identified in 102 (76%) patients, including altered mental status (71.1%), weakness (26.4%), and falls (24.8%). Respiratory failure occurred in 65.8% of patients, with 35.4% requiring ventilators while 22.3% of patients died. Age, male gender, SOB, sepsis, and certain laboratory values were associated with outcomes.ConclusionHospitalized older adults infected with SARS-CoV-2 may present with a range of symptoms encompassing typical, atypical, and geriatric syndromes. Early testing for COVID-19 should be considered in hospitalized older adults.

Project description:BackgroundOSA is associated with increased risks of respiratory complications following surgery. However, its relationship to the outcomes of hospitalized medical patients is unknown.MethodsWe carried out a retrospective cohort study of patients with pneumonia at 347 US hospitals. We compared the characteristics, treatment, and risk of complications and mortality among patients with and without a diagnosis of OSA while adjusting for other patient and hospital factors.ResultsOf the 250,907 patients studied, 15,569 (6.2%) had a diagnosis of OSA. Patients with OSA were younger (63 years vs 72 years), more likely to be men (53% vs 46%), more likely to be married (46% vs 38%), and had a higher prevalence of obesity (38% vs 6%), chronic pulmonary disease (68% vs 47%), and heart failure (28% vs 19%). Patients with OSA were more likely to receive invasive (18.1% vs 9.3%) and noninvasive (28.8% vs 6.8%) forms of ventilation upon hospital admission. After multivariable adjustment, OSA was associated with an increased risk of transfer to intensive care (OR, 1.54; 95% CI, 1.42-1.68) and intubation (OR, 1.68; 95% CI, 1.55-1.81) on or after the third hospital day, longer hospital stays (risk ratio [RR], 1.14; 95% CI, 1.13-1.15), and higher costs (RR, 1.22; 95% CI, 1.21-1.23) among survivors, but lower mortality (OR, 0.90; 95% CI, 0.84-0.98).ConclusionAmong patients hospitalized for pneumonia, OSA is associated with higher initial rates of mechanical ventilation, increased risk of clinical deterioration, and higher resource use, yet a modestly lower risk of inpatient mortality.
