  • Development and validation of a predictive algorithm for risk of dementia in the community setting

    Open AccessStacey Fisher, Douglas G Manuel et al.ARTICLEJournal of Epidemiology and…2021Referencias: 32

    BACKGROUND: Most dementia algorithms are unsuitable for population-level assessment and planning as they are designed for use in the clinical setting. A predictive risk algorithm to estimate 5-year dementia risk in the community setting was developed. METHODS: The Dementia Population Risk Tool (DemPoRT) was derived using Ontario respondents to the Canadian Community Health Survey (survey years 2001 to 2012). Five-year incidence of physician-diagn…

  • Influenza and Seasonal Patterns of Hospital Use by Older Adults in Long-Term Care and Community Settings in Ontario, Canada

    Andrea Gruneir, Jeff C Kwong et al.ARTICLEAmerican Journal of Public Health2014Referencias: 22

    Objectives. We compared seasonal influenza hospital use among older adults in long-term care (LTC) and community settings. Methods. We used provincial administrative data from Ontario to identify all emergency department (ED) visits and hospital admissions for pneumonia and influenza among adults older than 65 years between 2002 and 2008. We used sentinel laboratory reports to define influenza and summer seasons and estimated mean annual event ra…

  • Using the Johns Hopkins Aggregated Diagnosis Groups (ADGs) to Predict Mortality in a General Adult Population Cohort in Ontario, Canada

    Peter C Austin, Carl van Walraven et al.ARTICLEMedical Care2011Referencias: 15

    BACKGROUND: Administrative healthcare databases are increasingly used for health services and comparative effectiveness research. When comparing outcomes between different treatments, interventions, or exposures, the ability to adjust for differences in the risk of the outcome occurring between treatment groups is important. Similarly, when conducting healthcare provider profiling, adequate risk-adjustment is necessary for conclusions about provi…

  • The Relationship Between Variations in Antipsychotic Prescribing Across Nursing Homes and Short-Term Mortality

    Susan E Bronskill, Paula A Rochon et al.ARTICLEMedical Care2009Referencias: 34

    BACKGROUND: High rates of antipsychotic drug prescribing in nursing homes can signal poor quality processes, but also raise concerns about drug safety due to the mortality risk of this therapy. Determining the extent to which variations in antipsychotic use are a symptom of facility-level quality problems as compared with a drug safety issue is important for selecting the correct interventions to effect change. OBJECTIVE: To determine whether nur…

  • Hospitalization for Ambulatory Care-Sensitive Conditions

  • Hospital Restructuring and the Epidemiology of Hospital Utilization

    Gregory M Anderson, Geoffrey M AndersonARTICLEMedical Care1997Referencias: 8

    OBJECTIVES: The author highlights changes in hospital utilization that have occurred in association with restructuring of Ontario hospitals. The basic features of the epidemiology of hospital utilization described link the analysis of the organizational and structural components of hospitals with a more comprehensive evaluation of the impacts of their restructuring and have implications for international comparative studies. METHODS: Data from th…

  • Recent Findings On Preventable Hospitalizations

    John Billings, Gregory M Anderson et al.ARTICLEHealth Affairs1996

    Disparities in health outcomes for low-income populations as documented by rates of preventable hospital admission remains large in the United States, even with the moderate expansion of Medicaid and efforts at the state and local levels to improve primary care services that began in the mid-1980s. These differences in outcome for rich and poor are not an isolated phenomenon of a few old and decaying Northeast urban centers but are documented in …

  • A Comparison of Cost-Sharing Versus Free Care in Children

    Gregory M Anderson, Geoffrey M Anderson et al.ARTICLEMedical Care1991

    Using data from the community based RAND Health Insurance Experiment, the effect of cost-sharing versus free care on the use of office-based medical care in children was examined. Children from families on cost-sharing plans had a 22 percent lower probability (P less than 0.005) of having an episode of care during the study year. Both the number of episodes of care and total charges for outpatient professional services were 30 percent lower (P le…

  • Regionalization of Coronary Artery Bypass Surgery

    Gregory M Anderson, Geoffrey M Anderson et al.ARTICLEMedical Care1989

    Coronary artery bypass surgery (CABS) has been regionalized in the province of Ontario since the introduction of the procedure in the 1970s. The authors examined the effect of regionalization on the age-adjusted surgery rates in the 38 counties of southern Ontario and found that county surgical rates were not related to whether the county had a referral center, bordered on a county with a referral center, or did not border on such a county (R2 = …
