Use of ambulatory care resources by Medicare-age patients in a primary care group practice.

The increase in the number of persons age 65 and over-the Medicare-age group-and the increasing cost of providing medical care to patients in this group have focused attention on enrollment of these persons in capitated plans as a means of containing costs. Although much is known about resources used for inpatient care for Medicare-age patients, detailed information organized on a per-patient, per-year basis about ambulatory care of these patients is lacking. In order to address this problem and to investigate possible differences in resource use by age groups within the Medicare-age population, a study was made of a primary care group practice in which 523 patients, including 174 patients in the Medicare-age group, were followed for one year to determine their use of ambulatory care resources. A comparison of annual resource use by patients age 75 and over with patients age 65 through 74 showed that patients age 75 and over made more visits for primary care (8.15 vs. 6.46), made more visits to specialty and subspecialty clinics (3.41 vs. 2.33) and had higher total charges for ambulatory care ($749 vs. $623). The pattern of use of specialty and subspecialty clinics suggests that the primary care physicians functioned effectively as gatekeepers because most medical problems were handled without referrals to medical subspecialty clinics. The pattern also suggests that the projected rapid increase between now and the year 2000 in the number of persons age 75 and over may result in a greater than anticipated demand for services provided by ophthalmologists, podiatrists, and otolaryngologists.

Ambulatory care classification systems.

This article describes several methods of classifying resources used in ambulatory care into isoresource consumption groups. These methods are based on resources used by patients during a year, rather than on resources used in a single visit. Variables used to partition patient-year charges into isoresource consumption groups are age, race, number of health problems or major diagnostic categories addressed, number of medications or categories of medications prescribed, and indexes developed to reflect resources used by diagnostic categories during a patient-year. Confirmation in other settings of the findings of this study would have important implications for the design of prospective payment plans for ambulatory care.

The use of negative indexes of health to evaluate quality of care in a primary-care group practice.

A quality assessment method using negative indexes of health as a measure of the quality of medical care was applied in a hospital-based primary-care group practice. During a 5-year period, records of 1,147 patients were analyzed. The study led to several observations regarding the use of this method in this setting: 1) The negative indexes of health method encourages physicians to include both primary and secondary preventive measures in their practice of medicine and to see their role as a broad one, from providing good care to individual patients to influencing public policy. 2) Most medical records do not now contain all the data required for use of this method. 3) In cases where this method identifies only a few instances of possibly preventable disease or untimely death, it is impossible to know whether the care is good and the method of evaluation is sensitive, or whether the care is poor and the method is insensitive to deficiencies in care.

Classification of ambulatory care using patient-based, time-oriented indexes.

This paper presents a new approach to the classification of ambulatory care into isoresource consumption groups. In contrast to classification schemes based on visits, this case-mix approach creates an index based on resources used by diagnostic categories by a patient during a year. An application of this method to a primary care, group practice data base produced resource consumption groups with coefficients of variation in an acceptable range compared with the coefficients of variation of the diagnosis-related groups used to classify inpatient care.

Comparison of two therapeutic regimens using the same topical corticoid for stable psoriasis.

In a masked, randomized, concurrently controlled clinical trial we compared the therapeutic response of two regimens in which the same topical corticoid was used to treat 52 men who had stable psoriasis. One regimen, called reduced dose, consisted of once-a-day application of a representative potent fluorinated topical steroid ointment, fluocinonide (Lidex), combined with three-times-a-day application of its vehicle. The other regimen, called traditional dose, consisted of four-times-a-day topical application of the same steroid. Patients were assigned to one of the two regimens and observed for six weeks. Confidence intervals for the difference in true mean response under these two regimens provide good evidence that for these patients the traditional dose was not clinically superior to the reduced dose.

A problem-oriented approach to medical information systems: an application in a primary care group practice.

A relatively simple computer-based information system developed for a primary care group practice at the San Francisco Veterans Administration Hospital contributes to the management of the practice, to improvement of medical care for patients within the group, and to research studies on resource utilization in the management of chronic diseases and the evaluation of care of chronically ill patients. Preliminary results from the use of the information system are encouraging and demonstrate that much may be achieved by information systems that do not attempt to computerize the entire medical record.

A physician extender training program based on clinical algorithms.

The ability of physician extenders to provide patient care in a variety of settings has been reported widely. Less attention has been paid to training programs, especially those of short duration, for physician extenders. A three-month training program for physician extenders at a large teaching hospital was based on teaching the skills needed to run 39 clinical algorithms. The course content and the methods used to test the students during the three months may prove of value to those preparing similar programs.
