Alcohol problems and sense of coherence among older adults.

The relation between alcohol problems and sense of coherence (SOC), a salutogenic model developed by Antonovsky, was assessed on a sample of 952 older members of a health maintenance organization. Data on alcohol problems (5-item index) and SOC (9-item scale) were obtained from mailed questionnaires. Multiple regression analyses indicated that SOC was a significant negative predictor of alcohol problems while controlling for alcohol consumption level, frequency of drunkenness and demographic characteristics. In addition, SOC scores were significantly higher for a subsample of lighter drinkers who reported no alcohol problems in the last year and had not been drunk in the last year (n = 419) as compared to heavier drinkers who reported at least one alcohol problem in the last year, and reported being drunk at least once in the last year (n = 107). These findings emphasize the importance of assessing factors which contribute to healthier behaviors as opposed to focusing exclusively on predictors of pathogenic outcomes.

Home blood pressure monitoring. Effect on use of medical services and medical care costs.

The objective of this study was to determine whether a hypertension management program in which patients monitor their own blood pressure (BP) at home can reduce costs without compromising BP control. The prospective, randomized, controlled 1-year clinical trial was conducted at four medical centers of the Kaiser Permanente Medical Care Program in the San Francisco Bay Area. Of 467 patients with uncomplicated hypertension who were referred by their physicians, 37 declined to participate in the study; 215 were randomly assigned to a Usual Care (UC) group and 215 to a Home BP group. Twenty-five UC patients and 15 Home BP patients did not return for year-end BP measurements. Patients in the UC group were referred back to their physicians. Patients in the Home BP group were trained to measure their own BP and return the readings by mail. Patients were given a standard procedure to follow in case of unusually high or low BP readings at home. The number and type of outpatient medical services used were obtained from patient medical records for the study year and the prior year. Costs of care for hypertension were calculated by assigning relative value units to each outpatient service. Trained technicians measured each patient's BP at entry into the study and 1 year later. Home BP patients made 1.2 fewer hypertension-related office visits than UC patients during the study year (95% confidence interval (CI): 0.8, 1.7). Mean adjusted cost for physician visits, telephone calls, and laboratory tests associated with hypertension care was $88.76 per patient per year in the Home BP group, 29% less than in the UC group (95% CI: $16.11, $54.74). The annualized cost of implementing the home BP system was approximately $28 per patient during the study year and would currently be approximately $15. After 1 year, BP control in men in the Home BP group was better than in men in the UC group; BP control was equally good in women in both groups. Management of uncomplicated hypertension based on periodic home BP reports can achieve BP control with fewer physician visits, resulting in substantial cost savings.

The effect of retirement on health services utilization: the Kaiser Permanente Retirement Study.

The relationship of retirement and use of medical services was investigated among members of the Kaiser Permanente Medical Care Program in Northern California. A mailed survey of a 10 percent random sample of members 60-66 years old (N = 10,202) was followed by a telephone interview of (a) all respondents who had planned to retire in the next year, and (b) a random sample of respondents who had not planned to retire: 253 had retired (Retired group) and 238 were still working 20 hours a week or more (Not Retired group). Medical charts were reviewed for one year before and after the retirement date for the Retired group and for one year before and after a randomly assigned anchor date for the Not Retired group. With the exception of urgent care and emergency visits, no significant difference was found between the two groups in overall use of outpatient and inpatient services following retirement.

Methodologic issues in evaluating stop smoking programs.

Three methodologic issues (definitions of smoking, period of follow-up, composition of study group) were assessed in 426 persons five years after participation in a stop smoking program of a prepaid medical plan. When smoking was defined by measurement interval or by type or amount of tobacco smoked, smoking rates varied only slightly. Little information was gained by extending the follow-up period beyond the first year. However, study group composition (as defined by attendance at program sessions) had a pronounced effect on smoking rates. Those who attended fewer sessions were more likely to smoke during the follow-up period.

Clinical methods in smoking cessation: description and evaluation of a stop smoking clinic.

This study reports the results of the Kaiser-Permanente Stop Smoking Clinic and describes the philosophy and methods employed by the clinic in treating addictive smoking behavior. Of the 1,128 clients who registered for the group program, 57 per cent are abstinent six months after quitting smoking and 47 per cent are abstinent at one year. The clinic methods used are described in detail. They attempt to relate smoking behavior to the larger phenomenon of addiction.

The role of nurse practitioners in hypertension care.

1. Two groups of hypertensive patients, randomly assigned to either physician or nurse practitioner care, were compared, after two years of follow up, with respect to diastolic blood pressure reduction and utilization and costs of medical services. In addition, satisfaction with hypertension are was evaluated. 2. There was no statistical difference in mean diastolic blood pressure reduction between the physician and nurse practitioner groups. 3. Patients in the nurse practitioner group made more visits for hypertension care than those in the physician group; thus, even though the cost per nurse practitioner visit was lower than the cost per physician visit, the total annual cost of care per patient was higher in the nurse practitioner group. 4. Patients followed by nurse practitioners were very satisfied with their care. 5. Nurse practitioners provide excellent hypertension care and thereby save valuable physician time.

Pilot study of discussion groups of "worried well" patients in an ambulatory care setting.

Two pilot discussion groups were conducted for patients who met selected criteria indicating they were worried well patients (not requiring conventional medical care services). The objective of the groups was to explore and demonstrate the feasibility of utilizing an educational approach conducted by paraprofessional personnel, under physician supervision, for helping to meet the needs of such patients, thereby reducing utilization of more expensive physician resources. The findings indicated that 50 percent of the patients reduced the number of visits to the physician, and 60 percent perceived the experience as helpful.

Influence of dosage and duration of therapy on the rate of response to methyclothiazide in essential hypertension.

One hundred twenty patients with essential hypertension were studied to determine whether patients who had not responded to the usual dose of a thiazide (methyclothiazide, 5 mg daily during a six-week drug trial) would respond to a higher dose (10 mg daily). The 14-week study was divided into three periods: (1) a two-week placebo period; (2) a six-week single-blind trial; and (3) a six-week period for double-blind dose comparison. Among the 77.3 percent of patients who responded to the drug, diastolic blood pressure was reduced to 90 mm Hg or lower. Two types of thiazide responders were identified-early and late. The early responders (50 percent of study patients), showed a significant reduction in diastolic blood pressure within four weeks; the late responders (27.3 percent) showed a modest reduction in diastolic blood pressure during the first four weeks of therapy, followed by a plateau lasting about two weeks, then a further significant reduction in blood pressure during the ensuing six weeks. Hypokalemia was more common in early responders. There were no significant differences in late response among patients who continued on the usual dose of methyclothiazide compared to those whose dosage was doubled, suggesting that the late response was not due to increasing the dose of the drug.

Evaluation of an ambulatory medical-care delivery system.

We designed a medical-care-delivery system specifically to relieve the impaired access to care that has invariably assompanied the elimination of personal fees by prepaid plans, Medicare and other third-party payment plans. The solution involved the entry of patients through a paramedically staffed health-evaluation servece that effectively separated patients into three basic health-status groups-the well and worried well (68.4 per cent); the asymptomatic sick (3.9 per cent); and the sick (27.7 per cent)--a process that permitted matching the needs of each group with appropriate services. The system achieved increased physician accessibility to new patients by 20 times, reduced the waiting time for new appointments from six to eight weeks to a day or two, saved physician time and costs for entry work to a day or two, saved physician time and costs for entry work-up by 70 to 80 per cent reduced total resources used throughout the year by +32,550 per 1000 entrants, and proved very satisfactory to patients and generally so to staff.
