Charting the winds of change: evaluating innovative medical curricula.

The increased interest, in North America and around the world, in problem-based and community-oriented medical curricula has sparked interest in the evaluation of these innovative programs. In January 1989, the Josiah Macy Jr. Foundation sponsored a conference to consider designs for evaluation studies and the potential distinctive outcomes of the innovative curricula that might be foci of these studies. After defining an "innovative curriculum," the participants identified seven characteristics of "important evaluation studies," particularly endorsing studies that compare curricula as whole entities. The participants then identified 26 areas where differences between graduates of innovative and traditional curricula might be expected, and five equally important areas where differences are not expected. Distinctive outcomes of innovative curricula were anticipated in areas such as interpersonal skills, continuing learning, and professional satisfaction. Overall, these recommendations are offered to stimulate creative evaluations of the growing number of innovative programs in medical education.

Human neuroelectric patterns predict performance accuracy.

In seven right-handed adults, the brain electrical patterns before accurate performance differed from the patterns before inaccurate performance. Activity overlying the left frontal cortex and the motor and parietal cortices contralateral to the performing hand preceded accurate left- or right-hand performance. Additional strong activity overlying midline motor and premotor cortices preceded left-hand performance. These measurements suggest that brief, spatially distributed neural activity patterns, or "preparatory sets," in distinct cognitive, somesthetic-motor, and integrative motor areas of the human brain may be essential precursors of accurate visuomotor performance.

An alternative in terminal care: results of the National Hospice Study.

Hospice is a program of supportive services for terminally ill patients and their families, provided either at home or in designated inpatient settings, which is purported to improve patient and family quality of life at lower cost than conventional terminal care. The National Hospice Study was a multi-site, quasi-experimental study to compare the experiences of terminal cancer patients and their families in hospices with those of similar patients and families receiving conventional terminal care. The results indicate that, although care is different in hospices, e.g. lesser utilization of aggressive interventional therapy and diagnostic testing, patients' quality of life is similar in the hospice and conventional care systems with the exception of pain and symptom control, which may be better in the inpatient hospice setting. Hospice patients are more likely to die at home and their families are satisfied with that outcome. Otherwise, no consistent superiority of family outcome was associated with the hospice approach. The cost of hospice care is less than that of conventional terminal care for patients in hospices without inpatient facilities, but the cost of hospice appears to be equivalent to conventional care for patients in hospices having beds.

The effect of treatment setting and patient characteristics on pain in terminal cancer patients: a report from the National Hospice Study.

Debilitating pain is the symptom most often associated with cancer by the general public. The National Hospice Study (NHS) evaluated pain control among terminal cancer patients served in hospital based (HB) and home based (HC) hospices, and in conventional care settings (CC) such as outpatient clinics and oncology units. Pain was reported by the patient when able to respond and by the patients' primary care person (PCP) during repeated interviews until death. Patient and PCP pain reports were correlated at 0.43. PCPs reported that around 16% of patients were pain free in the last weeks of life while 18% were in persistent pain. Statistically adjusting for differences in the CC, HB, and HC samples, HB patients were less likely to report having persistent pain than either CC or HC patients, although there were no differences in the proportion of patients who were pain free. Age was negatively correlated with the level of pain. As expected, brain and bone metastases were related to pain in opposite directions, with more pain among those with bone involvement and less among those with brain involvement. Conclusions about whether HB hospices really are superior at pain control must be made cautiously in view of the relationship between age and pain and the greater age of hospice patients in our study.

Analgesic use in terminal cancer patients: report from the National Hospice Study.

Little systematic research has been reported on analgesic use in terminal cancer patients. This paper presents data from the National Hospice Study on the use of analgesics by a sample of terminal cancer patients served in home based and hospital based hospice programs as well as conventional oncological settings. Patients in hospital based hospice programs were more likely than other patients to have an analgesic prescription and to have consumed analgesics. Patients in hospice settings were more likely to consume analgesia orally and less likely to have "prn" (as needed) analgesic prescriptions. The amount of analgesic consumption was inversely related to age. The paper discusses the implications of these and other findings for the treatment of pain in terminal cancer patients.

Active life expectancy.

This study was designed to demonstrate the feasibility of forecasting functional health for the elderly. Using life-table techniques, we analyzed the expected remaining years of functional well-being, in terms of the activities of daily living, for noninstitutionalized elderly people living in Massachusetts in 1974. The expected years, or active life expectancy, showed a decrease, from 10 years for those aged 65 to 70 years to 2.9 for those 85 or older. Active life expectancy was shorter for the poor than for others, and women had a longer average duration of expected dependence than men. The measure of active life expectancy provides important information about health at a given population level, in terms other than death. This information can be used for actuarial purposes in planning and policy making. It is also useful in identifying high-risk populations for which preventive health care and medical care can compress morbidity during the last years of life.

National hospice study analysis plan.

Since the founding of the first hospice in the United States in 1974, the number of health care organizations providing hospice services has grown rapidly. In 1978, the U.S. General Accounting Office identified 59 operational hospices [1]. A survey undertaken by the National Hospice Organization (NHO) in 1980 found 235 operational programs and many more actively planning to deliver services. By the summer of 1981, the Joint Commission on the Accreditation of Hospitals (JCAH), in studying the feasibility of a voluntary hospice accreditation program, had 650 responses to a national survey [2]. Finally, the 1981 NHO directory identifies 464 operational "provider programs" as well as 33 functioning state-level hospice organizations with an additional 353 programs in various stages of establishing hospice programs of care [3]. The growth of the movement and the public recognition it has received have catalyzed advocacy of Federal support for hospice services. In 1979, the Congress responded by mandating a study to delineate the implications of inclusion of hospice services in the Medicare program. The Health Care Financing Administration (HCFA) then selected 26 hospices (from an applicant pool of 233) to participate in a two-year experimental program. These demonstration sites receive reimbursement for services provided Medicare beneficiaries not otherwise available under current regulations. The special reimbursement provisions went into effect on October 1, 1980. (See Appendix A: Description of the Hospice Reimbursement Program.) In the spring of 1980, the Robert Wood Johnson Foundation and the John A. Hartford Foundation joined with the Health Care Financing Administration (HCFA) to solicit proposals for a national evaluation of hospice care as a basis for future Federal fiscal policy and legislation. Brown University was selected as the evaluation center by competitive process and the grant was awarded on September 30, 1980. The evaluation employs a quasi-experimental design in which the impact of hospice care (with and without reimbursement) on quality of life and costs are compared to non-hospice (conventional) terminal care. Eight hundred patients and families in 24 comparison sites located in three regional areas (Southern New England, Northern Midwest and Southern California) are expected to participate. Primary data collection began on August 1, 1981. Analyses of differential outcome are performed using standard linear multiple regression and logistic multiple regression with separate models for each comparison group. Effects are tested by separately estimating the specific response variable for the prototype (average) hospice patient for each model.
