Impact of Adherence to Quality Measures for Localized Prostate Cancer on Patient-reported Health-related Quality of Life Outcomes, Patient Satisfaction, and Treatment-related Complications
BACKGROUND AND OBJECTIVE: Quality measures used in pay-for-performance systems are intended to address specific quality goals, such as safety, efficiency, effectiveness, timeliness, equity, and patient-centeredness. Given the small number of narrowly focused measures in prostate cancer care, we sought to determine whether adherence to any of the available payer-driven quality measures influences patient-centered outcomes, including health-related…
Understanding Disparities in Lipid Management Among Patients with Type 2 Diabetes
Patient Complexity and Risk Factor Control Among Multimorbid Patients With Type 2 Diabetes
BACKGROUND: Among patients with type 2 diabetes, it is not known whether risk factor control is better or worse for those who also have heart disease, depression, multiple other comorbidities, and associated management challenges. OBJECTIVE: To examine the relationship between this complex constellation of multimorbidities, adherence to treatment and risk factor control among patients with type 2 diabetes, independent of regimen intensity. RESEAR…
Who Can Respond to Treatment
BACKGROUND: Interest in comparative effectiveness research and the rising number of negative or "small effect" trials have stimulated research into differential response to treatment among subgroups of patients. OBJECTIVE: To develop and test the Potential for Benefit Scale (PBS), a composite measure to identify subgroups of patients with differential potential for response to treatment, using diabetes as a model. DESIGN: Cross-sectional and long…
Improving the Reliability of Physician Performance Assessment
BACKGROUND: The proliferation of efforts to assess physician performance underscore the need to improve the reliability of physician-level quality measures. OBJECTIVE: Using diabetes care as a model, to address 2 key issues in creating reliable physician-level quality performance scores: estimating the physician effect on quality and creating composite measures. DESIGN: Retrospective longitudinal observational study. SUBJECTS: A national sample o…
Preliminary psychometric evaluation of the Child Health Ratings Inventory (CHRIs) and Disease-Specific Impairment Inventory-Hematopoietic Stem Cell Transplantation (DSII-HSCT) in parents and children
Better physician-patient relationships are associated with higher reported adherence to antiretroviral therapy in patients with HIV infection
Optimal Methods for Guideline Implementation
BACKGROUND: Quality problems in medical care are not a new finding. Variations in medical practice as well as actual medical errors have been pointed out for many decades. The current movement to write practice guidelines to attempt to correct these deviations from recommended medical practice has not solved the problem. OBJECTIVE: In order to gain greater acceptance of these guidelines and to change the behavior of health care providers, the sci…

Using patient reports to assess health-related quality of life after total hip replacement
The Importance of Co-existent Disease in the Occurrence of Postoperative Complications and One-Year Recovery in Patients Undergoing Total Hip Replacement
Co-existent or comorbid diseases are appreciated as prognostic factors in studies of quality and effectiveness of care when mortality is the end point. The need to measure and adjust for comorbidity in studies of postoperative hospital complications or long-term recovery from surgery has not been documented. In this study, we determined the impact of co-existent disease on post-operative complications and 1-year health-related quality of life in …
Ambulatory Testing for Capitation and Fee-For-Service Patients in the Same Practice Setting
Previous studies of the impact of varying reimbursement incentives on physician behavior have not explored the simultaneous implications for patients' health outcomes. Using a single group of physicians who provided care for hypertensive patients with either capitation (N = 99) or fee-for-service (N = 66) health insurance plans, physicians' test-ordering behavior and patients' subsequent health outcomes were examined. After controlling for patien…
Assessing the Effects of Physician-Patient Interactions on the Outcomes of Chronic Disease
Growing interest in the doctor-patient relationship focuses attention on the specific elements of that relationship that affect patients' health outcomes. Data are presented for four clinical trials conducted in varied practice settings among chronically ill patients differing markedly in sociodemographic characteristics. These trials demonstrated that "better health" measured physiologically (blood pressure or blood sugar), behaviorally (functio…
Patients’ participation in medical care
Agreement Among Physician Assessment Methods Searching for the Truth Among Fallible Methods
To determine the convergent validity of four methods of physician assessment--physician interview, patient interview, chart audit, and videotaped observation--these methods were compared for their ability to detect medication regimens prescribed for patients with chronic obstructive pulmonary disease (COPD). Comparisons of data from the four methods revealed substantial discrepancies among them. In fact, the methods were in full accord only 36% o…
Expanding Patient Involvement in Care
An intervention was developed to increase patient involvement in care. Using a treatment algorithm as a guide, patients were helped to read their medical record and coached to ask questions and negotiate medical decisions with their physicians during a 20-minute session before their regularly scheduled visit. In a randomized controlled trial we compared this intervention with a standard educational session of equal length in a clinic for patients…
The survival benefit of bystander cardiopulmonary resuscitation in a paramedic served metropolitan area
We investigated the survival benefit bystander cardiopulmonary resuscitation (CPR) for out-of-hospital emergencies in a paramedic served area of metropolitan Los Angeles. Clinical information for all events occurring between January 1 and December 31, 1978 was obtained from paramedic report forms and hospital medical records. Bystander CPR was performed for 93 cases and, of these, 20 (22 per cent) survived to hospital discharge, as compared to 7 …
Patient Suffering and Patient Satisfaction Among the Chronically Ill
In a patient population with serious, debilitating chronic disease, the present study tested the hypothesis that a significant amount of variance in patient satisfaction ratings of provider behavior would be explained by patients' current assessment of their health and their social circumstances. More favorable patient ratings of the art, technical quality and efficacy of their care givers were found to be significantly associated with more posit…
Comparison of a Criteria Map to a Criteria List in Quality-of-Care Assessment for Patients with Chest Pain
In a prospective study we compared the ability of two quality assessment methods--the standard criteria list and the criteria map--to predict the appropriateness of the disposition decision for 421 patients with chest pain who presented to two emergency departments. To evaluate the quality of this decision, each patient was followed at home or in the hospital to determine whether an acute condition requiring hospital admission was present. Among …
Factors Associated with Relief from Chest Pain Following Emergency- Care
A preliminary study was conducted to explore a range of factors that may be associated with relief from chest pain. Nonhospitalized ambulatory patients (N = 150) were interviewed in their homes shortly after seeking care at one of two hospital emergency rooms. Bivariate and multivariate analyses identified four factors positively correlated with symptom relief: whether someone accompanied the patient to the emergency room; whether the patient fea…
