Patient Advisory Committee for a Chronic Opioid Therapy Risk Reduction Evaluation
Separate meetings of the PAC and scientific team enhanced opportunities for patients to influence the study design, analyses and interpretation of evaluation results. Convening a large group of patients with diverse perspectives and experiences was productive and influential in guiding the evaluation. Patient selection and building rapport allowed PAC members with divergent perspectives to work together effectively
Prevalence of Chronic Pain and High-Impact Chronic Pain Among Adults — United States, 2016
Chronic pain, one of the most common reasons adults seek medical care (1), has been linked to restrictions in mobility and daily activities (2,3), dependence on opioids (4), anxiety and depression (2), and poor perceived health or reduced quality of life (2,3). Population-based estimates of chronic pain among U.S. adults range from 11% to 40% (5), with considerable population subgroup variation. As a result, the 2016 National Pain Strategy called…

METHODS: We conducted a single-blind, randomized, controlled trial in 14 primary care clinics in an integrated health care system in Washingt…
Age and Gender Trends in Long-Term Opioid Analgesic Use for Noncancer Pain
Objectives. We describe age and gender trends in long-term use of prescribed opioids for chronic noncancer pain in 2 large health plans. Methods. Age- and gender-standardized incident (beginning in each year) and prevalent (ongoing) opioid use episodes were estimated with automated health care data from 1997 to 2005. Profiles of opioid use in 2005 by age and gender were also compared. Results. From 1997 to 2005, age–gender groups exhibited a tota…
Diabetes and Poor Disease Control
OBJECTIVE: To hypothesize that patients with comorbid depression and diabetes and poor disease control will have poorer adherence to disease control medication and less likelihood of physician intensification of treatment. Many patients with diabetes fail to achieve American Diabetes Association Guidelines for glycemic, blood pressure and lipid control. Depression is a common comorbidity and may affect disease control through adverse effects on a…
Physician support for diabetes patients and clinical outcomes
This observational study suggests that, in community practice settings, physician differences in practical support may influence glycemic control outcomes among patients with diabetes
Common Chronic Pain Conditions in Developed and Developing Countries
Childhood Adversity, Early-Onset Depressive/Anxiety Disorders, and Adult-Onset Asthma
OBJECTIVES: To investigate a) whether childhood adversity predicts adult-onset asthma; b) whether early-onset depressive/anxiety disorders predict adult-onset asthma; and c) whether childhood adversity and early-onset depressive/anxiety disorders predict adult-onset asthma independently of each other. Previous research has suggested, but not established, that childhood adversity may predict adult-onset asthma and, moreover, that the association b…

An approach was developed to analyze community organization efforts aimed at advancing community health objectives. These organizational processes are referred to as community activation. METHODS. Information was gathered from 762 informants through a key informant survey condu…
Depression, anxiety, and social disability show synchrony of change in primary care patients
OBJECTIVES. The purposes of this study were to (1) characterize the social disability associated with the common psychiatric illnesses of primary care patients in terms of role dysfunction (self-care, family role, social role, occupational role) and (2) establish whether severity of psychiatric illness and disability level show synchrony of change. METHODS. A two-stage sample design was employed. In the first stage, 1994 consecutive attenders of …
Evaluating community-based nutrition programs
A pilot test of a survey of grocery store product displays was conducted to measure the amount of health-education information provided and the proportion of the display devoted to "healthier" products. Inter-rater reliability ranged between 0.73 and 0.78 for the healthiness indices and between 0.30 and 0.67 for the health education measures. Test-retest reliability ranged from 0.44 to 1.0
A statistical model of the duration of mental hospitalization
Data describing the Length of Stay in Maryland state mental hospitals of 2311 schizophrenic patients reported originally by Eaton and Whitmore (1977) were reanalyzed. When the mixed exponential distribution was fitted to the data by the method of maximum likelihood for a censored sample, it was found to provide an acceptable fit to the data in contradiction to the reported findings which employed inefficient estimation methods. The conceptual sim…

Methodologic issues in randomized trials of liaison psychiatry in primary care
Most anxiety, depressive, and substance abuse disorders are treated exclusively in the primary care health system. However, recognition and treatment of these disorders in primary care is deficient. Psychopharmacologic and psychotherapeutic interventions have been developed and proven effective in randomized trials in specialty care. However, the results of successful trials of mental health interventions in specialty settings may not generalize …
A Chronic Disease Score with Empirically Derived Weights
Different types of medication prescribed during a 6-month period for the treatment and management of chronic conditions were utilized in the refinement and validation of a chronic disease score. Prescription data, in addition to age and sex, were utilized to develop a chronic disease score based on empirically derived weights for each of three outcomes: total cost, outpatient cost, and primary care visits. The ability of the revised chronic disea…
The Role of the Primary Care Physician in Patientsʼ Adherence to Antidepressant Therapy
In this study, the authors attempted to determine predictors of adherence to antidepressant therapy and to identify specific educational messages, side effects, and features of doctor-patient collaboration that influence adherence. Patients newly prescribed antidepressants for depression at a health maintenance organization were identified by using automated pharmacy data and medical records review. Patients (n = 155) were interviewed 1 and 4 mon…
Organizing Care for Patients with Chronic Illness
Usual medical care often fails to meet the needs of chronically ill patients, even in managed, integrated delivery systems. The medical literature suggests strategies to improve outcomes in these patients. Effective interventions tend to fall into one of five areas: the use of evidence-based, planned care; reorganization of practice systems and provider roles; improved patient self-management support; increased access to expertise; and greater av…
