Symptom management in older primary care patients: feasibility of an experimental, written self-disclosure protocol.

BACKGROUND: Distress-driven symptoms are prevalent among older primary care patients and account for a large percentage of office visits and increased medical costs. An experimental written self-disclosure protocol has been shown to reduce symptoms and use of health care services in healthy adults. Written self-disclosure as a method for reducing symptoms has not been evaluated in the primary care setting. OBJECTIVE: To evaluate the feasibility of adapting an experimental written self-disclosure protocol for the primary care setting. DESIGN: Randomized, single-blind feasibility study. SETTING: University-based geriatric and internal medicine primary care clinics. PATIENTS: 45 patients 66 years of age or older without a psychiatric diagnosis. INTERVENTION: Three 20-minute writing sessions focusing on distressing experiences (in the intervention group) or health behaviors (in the control group). MEASUREMENTS: The feasibility outcomes were patient recruitment, protocol logistics, and patient and provider satisfaction. The clinical outcomes were somatic and distress symptoms, health care utilization, and associated costs. RESULTS: One third of patients screened were recruited; 96% of patients recruited completed the protocol. Clinic contact time was an average of 55 minutes per patient. Patients and providers reported high levels of satisfaction with the protocol. Reductions in symptoms were minimal for both groups. Use of outpatient services and associated costs decreased in both groups, but the reduction was twice as great in the treatment group as in the control group. CONCLUSIONS: Findings support the feasibility of implementing the protocol as a primary care intervention.

Psychosocial interventions for cancer: review and analysis using a three-tiered outcomes model.

This study describes a three-tiered measurement model for psychosocial interventions with cancer patients and compares this model to extant measurement strategies. Progress has been made toward demonstrating that psychosocial interventions reduce depression, anxiety, functional impairment, and symptoms. However, Chambless and Hollon (1998) note that the literature on psychosocial interventions for cancer fails to meet criteria for establishing treatment "efficacy" and does not address issues of cost-effectiveness. The lack of a timely model of clinical outcomes may be hindering demonstration of efficacy and wider implementation of these interventions. Outcomes assessed by 65 interventions were classified as Global Health Outcomes (medical endpoints, health-related quality of life (HRQOL), or resource utilization), Dimensions of HRQOL (distress, symptoms, functional ability, or interpersonal well-being), or Mechanisms of Action (evaluation of psychological or physiological processes). A total of 28% of reviewed studies assessed Global Outcomes, 82% assessed Dimensions of HRQOL, and 49% assessed Mechanisms of Action. While most studies assessed patients' symptoms and distress, measurements of resource utilization, HRQOL, and interpersonal HRQOL were under-reported. A greater emphasis on treatment costs, quality of life, and mediating/moderating processes associated with improvement in outcomes could inform decisions regarding allocation of health-care resources and lead to more widely available and efficient interventions for patients.

What is heartburn worth? A cost-utility analysis of management strategies.

OBJECTIVE: To determine the best treatment strategy for the management of patients presenting with symptoms consistent with uncomplicated heartburn. METHODS: We performed a cost-utility analysis of 4 alternatives: empirical proton pump inhibitor, empirical histamine2-receptor antagonist, and diagnostic strategies consisting of either esophagogastroduodenoscopy (EGD) or an upper gastrointestinal series before treatment. The time horizon of the model was 1 year. The base case analysis assumed a cohort of otherwise healthy 45-year-old individuals in a primary care practice. MAIN RESULTS: Empirical treatment with a proton pump inhibitor was projected to provide the greatest quality-adjusted survival for the cohort. Empirical treatment with a histamine2 receptor antagonist was projected to be the least costly of the alternatives. The marginal cost-effectiveness of using a proton pump inhibitor over a histamine2-receptor antagonist was approximately $10,400 per quality-adjusted life year (QALY) gained in the base case analysis and was less than $50,000 per QALY as long as the utility for heartburn was less than 0.95. Both diagnostic strategies were dominated by proton pump inhibitor alternative. CONCLUSIONS: Empirical treatment seems to be the optimal initial management strategy for patients with heartburn, but the choice between a proton pump inhibitor or histamine2-receptor antagonist depends on the impact of heartburn on quality of life.

Health-related quality of life and virologic outcomes in an HIV clinic.

OBJECTIVE: The purpose of this study was to describe the relationship between viral load and health-related quality of life (HRQOL) in a cohort of persons with human immunodeficiency virus (HIV) infection. DESIGN: We evaluated HRQOL measurements in a clinical cohort of HIV-positive patients recruited from a university-associated HIV primary care clinic. HRQOL instruments included the medical outcomes survey-short form-36(MOS-SF-36) from which mental and physical component summary scores (MCS and PCS) and subscale scores were calculated. RESULTS: Significant negative associations were found between viral load and SF-36 PCS, physical functioning (PF), role-physical (RP), bodily pain (BP), general health (GH), role-emotional (RE), and vitality (VT). Similar negative associations were found between CD4 cell count and SF-36 summary and subscale scores, with the notable exception of bodily pain. Multivariate analyses controlling for the effects of CD4 cell count and other clinical variables indicated viral load as an independent predictor of SF-36 PCS, RP, BP and VT scores. CONCLUSIONS: The relationship between viral load, a measure of HIV disease activity, and several dimensions of the SF-36, a patient-focused measure of HRQOL, appears to be strong and independent of CD4 cell count. These findings suggest that having a lower viral load positively impacts the quality of life of HIV-positive patients.

Evaluating the relationship between pain presentation and health-related quality of life in outpatients with metastatic or recurrent neoplastic disease.

Because cancer pain can in many cases be intermittent, the presence or absence of pain in ambulatory care patients on any given clinic visit may not be an accurate characterization of the impact of pain on functioning or health-related quality of life (HRQOL). The purpose of this study was to describe the relationship between temporal aspects of pain presentation and HRQOL among 187 stage III/IV cancer patients using the Brief Pain Inventory and the EORTC QLQ-C30. A total of 43% of patients reported pain the previous week, with 22% reporting no pain at the time of assessment. Differences between three pain groups (No Pain, Past Pain, and Current Pain) were significant for global HRQOL and five dimensions of HRQOL. Severity of pain was also associated with each dimension of HRQOL. This study highlights the complex relationship between pain presentation and HRQOL. The findings support the continuing need for detailed pain assessments among cancer patients treated in ambulatory care settings. Specifically, standardized, self-report measures of cancer pain that include 'frequency' as well as severity may be the most accurate approach to capture the impact of pain on HRQOL.

An intervention to increase physicians' use of adherence-enhancing strategies in managing hypercholesterolemic patients.

PURPOSE: Patients' lack of adherence to medical regimens frustrates many practicing physicians. This study was conducted to determine the effectiveness of a combined continuing medical education intervention in increasing physicians' adherence-enhancing skills and improving hypercholesterolemic patients' health. METHOD: A prospective, randomized, controlled trial was designed using a nested cohort of 28 community physicians throughout Alabama and 222 of their hypercholesterolemic outpatients. The intervention, carried out in 1998, consisted of three interactive case audio-conferences plus chart reminders. Physicians' learning was measured by unannounced standardized patients, and patients' health by serum cholesterol levels, weight, knowledge of hypercholesterolemia, self-reported dietary habits, and health status. RESULTS: No significant difference was found in the numbers of physician adherence-enhancing strategies, although the number did increase within the treatment group. There were significant differences in the intervention group's patients' knowledge of cholesterol management (p = .008) and significant reductions in their self-reported consumption of dietary fats (p = .002). A significant difference was found in the serum cholesterol level of men in the intervention group nine months after the intervention (p = .02). CONCLUSION: Combining a series of interactive case audio-conferences with chart reminders shows promise in increasing physicians' adherence-enhancing strategies. In chronic disease management, the problem of enhancing adherence remains complex.

Correlates of functional status in older patients with schizophrenia.

There is a growing recognition of the importance of quantifying the impact of illness on functional abilities. Measures of function frequently rely on a self-report. Few studies have directly assessed functional capacity in psychiatric patients, especially older ones who may be at an increased risk for disability. Subjects were 102 middle-aged and elderly outpatients with DSM-III-R or DSM-IV diagnosis of schizophrenia or schizoaffective disorder, and 66 normal comparison subjects, ranging in age from 45 to 86. The Direct Assessment of Functional Status (DAFS), a standardized measure of behavior during simulated daily activity tasks (i.e. time orientation, communication, transportation, finance, shopping, grooming and eating) was used to quantify levels of disability. Schizophrenic patients demonstrated significantly greater disability than normal subjects. An evaluation of specific behaviors indicated that the patients were significantly more limited than comparison subjects across all subscales of the DAFS except for grooming and eating. A lower level of formal education, greater severity of extrapyramidal symptoms, and greater cognitive deficits, but not severity of symptoms of schizophrenia, were related to lower DAFS scores. Relative to published findings, schizophrenic patients appeared more disabled than outpatients with major depression, but less disabled than those with Alzheimer's disease. The DAFS is a useful instrument for characterizing functional abilities in older patients with schizophrenia. Our findings of significant functional disability in older schizophrenic patients have implications for treatment as well as allocation of health-care resources.

Direct assessment of functional status in older patients with schizophrenia.

OBJECTIVE: There has been a growing trend in medicine to evaluate the impact of illness on functional abilities. Such studies typically rely on the patient's or caregiver's report. The goal of this study was to assess directly the functional capacity of psychiatric patients, especially older ones. METHOD: The subjects were 55 outpatients with schizophrenia and 72 normal persons ranging in age from 45 to 86 years. The subjects were administered the Direct Assessment of Functional Status Scale, which assess behaviour during simulated daily activity tasks in the areas of time orientation, communication, transportation, finance, shopping, grooming, and eating. RESULTS: The patients with schizophrenia had significantly greater disability than the normal subjects according to total scale scores as well as the communication, transportation, finance, and shopping subscale scores. Global cognitive status was the best predictor of total scale score. CONCLUSIONS: The Direct Assessment of Functional Status Scale is a promising instrument for functional assessment in outpatients with schizophrenia.

Hypnosis as an adjunct to medical care in the management of Burger's disease: a case report.

Burger's disease is a peripheral vascular disorder characterized by constricted blood flow, ischemic pain, and necrotizing tissue processes. This report describes the application of a brief hypnosis intervention in conjunction with standard medical procedures to increase peripheral blood flow in a patient with advanced Burger's disease. Using suggestions for foot warming and increased blood flow, substantial increases in surface foot temperature were obtained prior to and following an epidural sympathectomy. As a result, the procedure contributed to keeping necrotic tissue loss to a minimum, decreasing ischemic pain, and hopefully preventing the need for amputation. Treatment gains were maintained through discharge and at two month follow up. The results suggest that hypnosis may serve as a parsimonious, yet efficacious adjunct to standard medical care in the management of reduced peripheral blood flow in patients with Burger's disease. Further, it illustrates the feasibility of hypnosis as an adjunct treatment in busy, inpatient hospital settings.
