Predictors Of Retention In Hiv/Aids Care At The Yale-New Haven Hospital Nathan Smith Clinic: Exploratory Analysis Using The Community Careware Database, Chi Ngo Jan 2013

Predictors Of Retention In Hiv/Aids Care At The Yale-New Haven Hospital Nathan Smith Clinic: Exploratory Analysis Using The Community Careware Database, Chi Ngo

Public Health Theses

Background: A `test-and-treat' strategy for HIV prevention in the United States is a method that was proposed in an effort to curb and reduce HIV transmission. However, the magnitude of the limitations observed at the various stages in the spectrum of engagement in care can threaten the `test-and-treat' HIV prevention initiative because successful retention remains problematic. Based on the United States' retention statistics, approximately one fourth to one half of those who were diagnosed with HIV were out-of-care. This figure suggests we need more information about the best ways to retain HIV-infected individuals in care.

Objective: In order to determine …

Distinct Trends In 30-Day Observed And Risk-Standardized Mortality Rates Of Acute Myocardial Infarction Patients, 2005-2010, Caroline Yoo Jan 2013

Distinct Trends In 30-Day Observed And Risk-Standardized Mortality Rates Of Acute Myocardial Infarction Patients, 2005-2010, Caroline Yoo

Public Health Theses

In the effort of comparing health care quality across hospitals and profiling hospitals, the Centers for Medicare and Medicaid Services (CMS) utilize risk-standardized outcome in which the hospital-level outcome is standarized adjusting for patient-covariates using hierarchical model for patients outcome clustered within hospital. Even though standardized measure is useful for comparing hospitals, we believe the analysis of observed hospital-level outcome without standarization can reveal additional information at the hospital-level. The implication of using both types of mortality rates was studied in the context of analyzing 30-day mortality trend of Acute Myocardial Infarction (AMI) patients. Therefore the objective of this study …

Marital Satisfaction And Health Of Older Adults With Chronic Pain And Their Spouses: The Role Of Individual Differences In Attachment, Lu Zhou

Public Health Theses

Abstract

Attachment theory provides a useful framework for understanding how caregiving dyads maintain feelings of security in reaction to a loved one's chronic condition. To our knowledge, no existing research has examined associations among individual differences in attachment (anxiety, avoidance), health, and relationship satisfaction in later-life marriages in which one individual suffers from chronic pain. In this study, we examined similarity of attachment orientation between spousal caregivers and care recipients, and the influence of one's attachment orientation on one's own, as well as their partner's, depressive symptoms, physical conditions, and marital satisfaction.

Seventy-seven individuals with chronic pain and their spousal …
