Demographic and psychosocial correlates of physical activity in late life.
INTRODUCTION: According to the Centers for Disease Control and Prevention and the World Health Organization, increasing physical activity may help prolong health and preserve the quality of life in late adulthood. Physical activity has taken center stage as the behavior most likely to alter health. However, there is little recent population-wide information about the demographic and psychosocial correlates of physical activity in the elderly population. The purpose of the study was to identify the factors associated with older adults' frequency of physical activity. The study may have implications for preventive interventions. METHODS: Data for 12,611 community-dwelling people aged > or = 65 from the 1996-1997 Canadian National Population Health Survey were examined. Predictors of frequent versus infrequent self-reported physical activity lasting > 15 minutes were examined using logistic regression analyses. The predictor variables included geographic location, psychological distress (Generalized Distress Scale), demographic factors (age, gender, educational level, and marital status), perceived social support, chronic medical conditions, physical limitations due to injury, functional limitations, smoking behavior, and body mass index (BMI). RESULTS: Gender (male); younger age; higher levels of education; being unmarried; absence of chronic conditions, injuries, and functional limitations; lower BMI; social support (females); nonsmoking; region; and lower levels of psychological distress were associated with frequent physical activity in late life. Older adults in western Canadian provinces were more active than those in eastern provinces. CONCLUSIONS: The results will be useful for the design of interventions aimed at improving older adults' health behavior and other health and functional outcomes, especially for subgroups in particular need. Recommendations for further longitudinal research are presented.

Consumer, provider, and informal caregiver opinions on psychiatric advance directives.
Psychiatric advance directives (PADs) are legal documents that permit competent adults to make choices in the present about their future psychiatric treatment if they lose their decision-making capacity. PADs may provide for the appointment of surrogate decision-makers. The present project was undertaken to obtain opinions from the consumer (the patient), provider, and informal caregiver/surrogate about the Oregon PAD. Results of this pilot study show that the majority of no-PAD group consumers reported that they did not get enough help with PAD preparation. The PAD group consumers reported feeling empowered by PAD preparation, but at the follow-up interview, they were less enthusiastic and more critical of PAD policy that was relevant to implementation. Many providers also were concerned about successful PAD implementation. PAD legislation alone does not translate into adequate policy.

Access to substance abuse treatment services under the Oregon Health Plan.
CONTEXT: The shift to Medicaid managed care has raised numerous concerns about access to publicly funded substance abuse treatment. The implementation of a capitated chemical dependency benefit within the Oregon Health Plan in 1995 provided an opportunity to study the impact of funding mechanisms on access. OBJECTIVES: To determine to what extent access to publicly funded substance abuse treatment changed following the shift to managed care in Oregon and to examine factors associated with that change. DESIGN: Analysis of statewide treatment and Medicaid eligibility data. SETTING AND PATIENTS: All Medicaid-eligible persons aged 12 to 64 years who were enrolled in the Oregon Health Plan during 1994 (88,320), 1996 (170,387), 1997 (160,929), or 1998 (149,877). MAIN OUTCOME MEASURES: Access rates (the number of unique individuals admitted to treatment during a calendar year divided by the average number of enrolled members) computed before (1994) and after (1997) implementation of the capitated benefit. Analyses were replicated with data for 1996 and 1998. RESULTS: The percentage of Medicaid-eligible persons admitted to substance abuse treatment programs during a calendar year increased from 5.5% of the average number of enrolled members per month in 1994 to 7.7% in 1997, following the shift to managed care. For 1996 and 1998, the rates were 6.9% and 7.7%, respectively. Access rates varied considerably among the 7 largest prepaid health plans after adjusting for case mix. Operating characteristics of these prepaid health plans, such as the method of reimbursing treatment providers, were significant predictors of access after controlling for member characteristics. CONCLUSION: According to our analyses, Medicaid-eligible persons in Oregon observed an increase in access to substance abuse treatment after a shift to managed care. JAMA. 2000;284:2093-2099.

Lessons learned.
Mental health care reform in the public sector remains a local proposition. Oregon has thus far been able to avoid major failures and has modest successes to report. Although the road to achieving all that was envisioned at the outset remains long, the inclusive process followed gives reason for hope.

Overview of Medicaid managed behavioral health care.
The Oregon Health Plan is being implemented at a time when many states are revising their Medicaid mental health programs. A national overview places this state's efforts into context.
Capitation Fee↗
Background on the Oregon Health Plan.
Because of limited resources, the health care industry has been forced to choose how funds are spent. Public fee-for-service systems have begun to face the hard choices inherent in managed care. The Oregon Health Plan was designed to provide a rational approach to addressing these changes directly.

The validity of medicaid pharmacy claims for estimating drug use among elderly nursing home residents: The Oregon experience.
This study compared computerized Medicaid pharmacy claims data for nursing home residents with chart data to establish how well the claims data identified those receiving drugs within three different psychoactive drug classes (yes/no for each class) and how well the claims estimated total within-class average daily dose. Percent agreement, positive predictive value (PPV), and negative predictive value (NPV) for drug exposure were over 85% for each class. Kappas were excellent for antipsychotics and antidepressants, and good for anxiolytics. Correspondence was lower for average daily dose. Using an algorithm that credits some but not all doses associated with overlapping claims, correlations ranged from 0.97 to 0.66. Agreement on therapeutic dose was excellent for antipsychotics (kappa = 0.81) and fair to good for antidepressants and anxiolytics (kappa = 0.63, and kappa = 0.52, respectively). The findings suggest that Medicaid pharmacy claims data are reasonably accurate for quality assurance and accreditation purposes.

Controlled trials of CQI and academic detailing to implement a clinical practice guideline for depression.
BACKGROUND: The release of the Agency for Health Care Policy and Research (AHCPR)'s Guideline for the Detection and Treatment of Depression in Primary Care created an opportunity to evaluate under naturalistic conditions the effectiveness of two clinical practice guideline implementation methods: continuous quality improvement (CQI) and academic detailing. A study conducted in 1993-1994 at Kaiser Permanente Northwest Division, a large, not-for-profit prepaid group practice (group-model) HMO, tested the hypotheses that each method would increase the number of members receiving depression treatment and would relieve depressive symptoms. METHODS: Two trials were conducted simultaneously among adult primary care physicians, physician assistants, and nurse practitioners, using the same guideline document, measurement methods, and one-year follow-up period. The academic detailing trial was randomized at the clinician level. CQI was assigned to one of the setting's two geographic areas. To account for intraclinician correlation, both trials were evaluated using generalized equations analysis. RESULTS: Most of the CQI team's recommendations were not implemented. Academic detailing increased treatment rates, but--in a cohort of patients with probable chronic depressive disorder--it failed to improve symptoms and reduced measures of overall functional status. CONCLUSIONS: New organizational structures may be necessary before CQI teams and academic detailing can substantially change complex processes such as the primary care of depression. New research and treatment guidelines are needed to improve the management of persons with chronic or recurring major depressive disorder.

An administrative model for close monitoring and managing high risk individuals.
The public expects central government to have immediate knowledge of the condition and circumstances of certain vulnerable or dangerous individuals such as insanity acquittees, and to take action in individual cases to protect the individual and the public. Therefore, such persons conditionally released to community settings require an unusual degree of close monitoring and management. Being immediately aware of the condition and circumstances of its assignees, together with other duties of a board or commission responsible for that monitoring and management, is largely an information management function. The Psychiatric Security Review Board in Oregon is used to illustrate this unique mission, operations, and information management. In this paper, the Psychiatric Security Review Board is described in terms of its core and secondary businesses, together with a model information system that is based on information and information management processes actually employed by the Board.

Attitudes of patients with amyotrophic lateral sclerosis and their care givers toward assisted suicide.
BACKGROUND AND METHODS: Amyotrophic lateral sclerosis (ALS) is a neuromuscular disease that causes gradual paralysis, respiratory failure, and death, usually within three to five years after it has been diagnosed. Between 1995 and 1997, we surveyed patients with this disease in Oregon and Washington, as well as their family care givers, in order to determine their attitudes toward assisted suicide. Patients were considered to be willing to contemplate assisted suicide if they agreed with the statement, "Under some circumstances I would consider taking a prescription for a medicine whose sole purpose was to end my life," and disagreed with the statement, "I would never request or take a prescription for a medication whose sole purpose was to end my life." The Oregon Death with Dignity Act, which legalized physician-assisted suicide, was approved by Oregon voters in 1994 but did not go into effect until October 1997, after data collection for this study had been completed. RESULTS: Of 140 eligible persons with ALS, 100 (71 percent) agreed to participate in the study, as did 91 family care givers. The mean age of the patients with ALS was 54 years; the mean duration of illness since the diagnosis was 2.8 years. Fifty-six patients (56 percent) said they would consider assisted suicide, and 44 of the 56 agreed with the statement, "If physician-assisted suicide were legal, I would request a lethal prescription from a physician." One patient would have taken the medication immediately, and 36 would have kept it for future use. As compared with the patients who were opposed to assisted suicide, those who would consider it were more likely to be men, had a higher level of education, were less likely to be religious, had higher scores for hopelessness, and rated their quality of life as lower. In 66 of 91 instances (73 percent), care givers and patients had the same attitude toward assisted suicide. CONCLUSIONS: In Oregon and Washington, a majority of persons with ALS whom we surveyed would consider assisted suicide. Many would request a prescription for a lethal dose of medication well before they intended to use it.

Comparing the use of short-acting and long-acting calcium channel blockers in an HMO.
One of the questions surrounding the controversy over the risks of MI among hypertensives taking calcium channel blockers (CCBs) is the dosage form, and whether the short-acting form may be more likely than the long-acting to increase the risk of MI. This preliminary study compared HMO members receiving the two dosage forms by sociodemographic and clinical characteristics, and by utilization (hospital, office visits, emergency room, outside of HMO services) prior to and during CCB use. The sampling frame was members with one or more dispensings for a CCB 1990 through 1994. Incident users were those who received one or more CCB dispensings and no cardiovascular disease-related drugs the year prior to their first dispensing of a CCB. CCB users were those who had at least 90 days of continuous CCB use. Short-acting outnumbered long-acting users by eight to one. Few incident users of long-acting CCBs were found. Among incident users, diagnoses and comorbidities were similar. In general, short-acting users appeared to have less risk of exposure to heart-related medications, but similar risks of exposure to non-heart-related drugs and to utilization of the various services during the year prior to first use. The odds of being exposed to heart-related medications and non-heart related medications and use of services during periods of use of CCBs were similar in general, but where differences were observed, the odds of being exposed were less among short-acting users. Users of the two dosage forms in this setting prior to reports questioning the safety of short-acting CCBs were different quantitatively and qualitatively making a retrospective comparative study difficult, perhaps not possible, due to substantial selection bias among users. Further patient selection bias has also undoubtedly occurred subsequent to the reports. The final answer to the relative safety and effectiveness of the different dosage forms of calcium channel blockers is likely to have come from randomized clinical trials.

Cancer recurrences and secondary primary cancers after use of antihistamines or antidepressants.
OBJECTIVES: Reports in the scientific literature have described accelerated tumor growth in association with antidepressant and antihistamine exposure in experimental rodent cancer models. This study was designed to determine whether exposure to prescription antidepressants or antihistamines is associated with tumor growth in humans. METHODS: Two nested case-control studies were conducted with a cohort of 1467 patients with breast cancer, colon cancer, or melanoma diagnosed between 1988 and 1994. Eligible patients included 95 with a cancer recurrence and 78 with a second primary lesion diagnosed during the follow-up period. Five control subjects were matched to each case patient according to cancer site, stage, and follow-up time. Conditional logistic regression was used to compare risk for tumor recurrence or occurrence of a second primary tumor among patients using antidepressants or antihistamines with risk among unexposed patients. RESULTS: For a cohort of patients who were predominantly female (78%), with breast cancer (57%) and with a tumor in situ or with localized disease (79%), the average age was 62 years at cancer diagnosis and average duration of follow-up period was 2.2 years. Use of antidepressants or antihistamines was unrelated to risk for tumor recurrence (odds ratio, 0.97; 95% confidence interval, 0.52 to 1.78) or second primary tumors (odds ratio, 0.94; 95% confidence interval, 0.50 to 1.77). CONCLUSION: Typical use of antidepressant or antihistamine drugs did not increase risk for recurrent or second primary tumors among patients with cancer.

Mental health in the Oregon Health Plan: fragmentation or integration?
The Oregon Health Plan was implemented in 1994 with a 50% expansion of Medicaid enrollment to include some of the working poor. Over 75% of Oregon Medicaid clients are now enrolled in health maintenance organizations (HMOs). Outpatient chemical dependency services have been capitated since May 1995. Capitated mental health services have been provided for the 25% of eligibles who live in demonstration counties since January 1995. Expansion and capitation appear to have been achieved without major trauma. More challenging has been the attempted integration of public sector behavioral health services with private sector health plans. Stakeholders interviewed for this study were especially concerned about the long-term impact on Medicaid clients with chronic mental illness. Strong leadership and clear policies regarding the mixture of public, private nonprofit, and private for profit entities are necessary if the state is to achieve its aim of integration without fragmenting a system of care for people with severe mental illness.
