Abstract
PURPOSE: This study examined the validity of medical-record-based nursing assessment and monitoring of signs and symptoms (nursing surveillance) in predicting patients who were admitted to ICUs and those admitted to non-ICUs. The association of this assessment and monitoring with differences in an intermediate patient outcome, instability at discharge, was also explored. Patients admitted to either setting with a diagnosis of acute myocardial infarction, cerebrovascular accident, congestive heart failure, or pneumonia, were included in the study. METHOD: A secondary analysis was carried out using a subset of data originally collected for a quality-of-care study. Data from the medical records of 11,246 patients (52% female, 48% male) with a mean age of 76.4 years were used in the present study. RESULTS: ICU patients (n = 3969) were found to have a longer length of stay and to be sicker on admission than non-ICU patients (n = 7277). Overall, patients in the ICU received significantly higher nursing assessment and monitoring of signs and symptoms scores than non-ICU patients. Nursing assessment and monitoring of signs and symptoms scores were lower for patients discharged with greater instability for three of the four diseases (cerebrovascular accidents, congestive heart failure, and pneumonia).

Abstract
BACKGROUND The relationship of do-not-resuscitate (DNR) orders to patient and hospital characteristics has not been well characterized. METHODS This observational study of a nationally representative sample of 14,008 Medicare patients hospitalized with congestive heart failure, acute myocardial infarction, pneumonia, cerebrovascular accident, or hip fracture evaluated the relationship of DNR orders to patient sickness at admission, functional impairment, age, disease, race, gender, preadmission residence, insurance status, and hospital characteristics. RESULTS Of the 14,008 patients, DNR orders were assigned to 11.6%. Patients with greater sickness at admission and functional impairment received more DNR orders (P < .001) but even among patients in the sickest quartile (with a 65% chance of death within 180 days), only 31% received DNR orders. The DNR orders were assigned more often to older patients after adjustment for sickness at admission and functional impairment (P < .001), and DNR order rates differed by diagnosis (P < .001). After adjustment for patient and hospital characteristics, DNR orders were assigned more often to women and patients with dementia or incontinence and were assigned less often to black patients, patients with Medicaid insurance, and patients in rural hospitals. CONCLUSIONS Do-not-resuscitate orders are assigned more often to sicker patients but may be underused even among the most sick. Sickness at admission and functional impairment do not explain the increase in DNR orders with age or the disparity across diagnosis. Further evaluation is needed into whether variation in DNR order rates with age, diagnosis, race, gender, insurance status, and rural location represents differences in patient preferences or care compromising patient autonomy.

Abstract
OBJECTIVE To improve functional status among primary care patients. INTERVENTION 1) Computer-generated feedback to physicians about the patient's functional status, the patient's self-reported "chief complaint," and problem-specific resource and management suggestions; and 2) two brief interactive educational sessions for physicians. DESIGN Randomized controlled trial. SETTING University primary care clinic. PARTICIPANTS All 73 internal medicine house officers and 557 of their new primary care patients. MEASURES 1) Change in patient functional status from enrollment until six months later, using the Functional Status Questionnaire (FSQ); 2) management plans and additional information about functional status abstracted from the medical record; and 3) physician attitude about whether internists should address functional status problems. RESULTS Emotional well-being scores improved significantly for the patients of the experimental group physicians compared with those of the control group physicians (p < 0.03). Limitations in social activities indicated as "due to health" decreased among the elderly (> or = 70 years of age) individuals in the experimental group compared with the control group (p < 0.03). The experimental group physicians diagnosed more symptoms of stress or anxiety than did the control group physicians (p < 0.001) and took more actions recommended by the feedback form (p < 0.02). CONCLUSIONS Computer-generated feedback of functional status screening results accompanied by resource and management suggestions can increase physician diagnoses of impaired emotional well-being, can influence physician management of functional status problems, and can assist physicians in improving emotional well-being and social functioning among their patients.

Abstract
The time spent in outpatient visits to a Veteran's Administration medical center was measured to determine clinic efficiency. Patient flow through the outpatient department of the medical center was studied to: 1) evaluate how time is spent in VA outpatient settings as compared to non-VA outpatient settings, including waiting time, checking of vital signs, seeing the doctor, etc., 2) develop a baseline to gauge the comparison of the effects of management changes; and 3) develop a mechanism for collecting clinic activity efficiency.

Abstract
BACKGROUND Successful implementation of modern ongoing quality improvement (QI) methods requires investment of institutional resources, but can produce significant improvements in medical care. A health care organization's goals and objectives for improving care are expressed in strategic plan documents, which could provide a framework for planning quality improvement initiatives. However, institutional strategic planning processes are often not well linked to QI staff and resources. We developed the Quality Action Program (QAP) to connect QI to strategic planning. HISTORY In 1991, Sepulveda VHAMC implemented a major primary care initiative, documented in a comprehensive strategic plan. The QAP was developed to enable the initiative to be evaluated within a QI context. THREE-ROUND EXPERT PANEL PROCESS: To carry out the QAP, members of an institution's quality council engage in a structured consensus process. The first round involves reading educational materials and filling out a quality action survey the second round includes participation in an expert panel meeting, and the third round involves making final priority rankings. EIGHT-STEP QAP IMPLEMENTATION PLAN: QI staff carry out activities to prepare for and carry out the three-round expert panel process. RESULTS QAP induced significant institutional QI activity directed toward achieving the top-ranked QI criterion--ensuring continuity of care. Continuity of care improved significantly over time between the pre- and post-QAP periods. CONCLUSIONS Expert panel methods can be used to link strategic plan goals and objectives to QI efforts.

Abstract
We reviewed rigorous evaluations of programs to enhance the quality and economy of primary care. We identified 36 evaluations published from 1980 through 1992. We abstracted data on objectives, setting(s), patients and processes, outcomes, and costs of care. We identified successful programs, as well as significant gaps in our knowledge of how to improve aspects of care. In specific, computer reminders and social influence-based methods fostered preventive and economic care. Nurse implementation of prevention protocols increased their performance. Multidisciplinary teams improved access and economy. Regional organization of practices or telephone management improved access; regionalization also reduced emergency care. Improvements were not found in continuity, comprehensiveness, humanistic process, physical environment, or health outcomes. Primary care practices can implement several programs to continuously improve prevention and access, and to reduce costs and use of unnecessary services. Research documenting how to accomplish other major goals, including health outcome changes, in different practice types is needed.

Abstract
The authors conducted a randomized controlled trial of functional disability screening in a hospital-based internal medicine group practice. They assigned 60 physicians and 497 of their patients to either an experimental or a control group. Every four months the patients in both groups completed a self-administered questionnaire measuring physical, psychological, and social function. The experimental group physicians received reports summarizing their patients' responses; the control group physicians received no report. At the end of one year the authors found no significant difference between the patients of the experimental and control group physicians on any measure of functional status. Functional disability screening alone does not improve patient function.

Abstract
OBJECTIVE To analyze whether elderly patients who are black or from poor neighborhoods receive worse hospital care than other patients, taking account of hospital effects and using validated measures of quality of care. DESIGN We compare quality of care provided to insured, hospitalized Medicare patients who are black or live in poor neighborhoods as compared with others, using simple and multivariable comparisons of clinically detailed measures of sickness at admission, quality, and outcomes. SETTING Two hundred ninety-seven acute care hospitals in 30 areas within five states. PATIENTS OR OTHER PARTICIPANTS The sample includes a nationally representative sample of 9932 patients 65 years of age or older who lived at home prior to hospitalization for congestive heart failure, acute myocardial infarction, pneumonia, or stroke. INTERVENTIONS This was an observational study. MAIN OUTCOME MEASURES Processes of care, length of stay, instability at discharge, discharge destination, and mortality. RESULTS Within rural, urban nonteaching, and urban teaching hospitals, patients who are black or from poor neighborhoods have worse processes of care and greater instability at discharge than other patients (P < .05). However, this worse quality is offset by patients who are black or from poor neighborhoods being 1.8 times more likely to receive care in urban teaching hospitals that have been shown to provide better quality of care (P < .001). Because these patients receive more of their care in better-quality hospitals, there are no overall differences in quality by race and poverty status. Death rates did not vary by race or poverty status. CONCLUSIONS Quality of hospital care for insured Medicare patients in influenced both by the patient's race and financial characteristics and by the hospital type in which the patient receives care.

Abstract
This paper provides and applies a conceptual framework and a list of guiding principles for evaluation of generalist education programs. Programs are systematic efforts to achieve specified objectives. Evaluations gather data in order to improve or appraise programs and have a continuum of purposes and methods. Descriptive evaluations characterize the structures, processes, and outcomes of programs; research evaluations definitively assess the effectiveness of a program in terms of outcomes. Intermediate outcomes are changes in knowledge, attitudes, and skills of program participants; conclusive outcomes reflect the quality of performance of graduates in actual clinical situations. Outcomes are affected by inputs--the qualities of students entering the program. Guiding principles of program evaluation ensure that data gathered are useful. The authors illustrate the guiding principles with an actual pilot study that determined that expert pediatricians, general internists, and family practitioners could agree on key generalist competencies and that explores evaluation design based on these competencies. Finally, they consider the implications of undertaking generalist education evaluation.

Abstract
PURPOSE To assess the value of functional status questions in predicting mortality, we conducted a 4-year prospective longitudinal follow-up study of functionally impaired community-dwelling elderly persons. SUBJECTS AND METHODS A total of 282 elderly (aged 64 years or older) patients of 76 community-based physicians who were UCLA clinical faculty members were assessed at baseline and at an average of 51 months later using scales from the Functional Status Questionnaire. RESULTS By the end of the study, 24% of the sample had died. By means of a multivariate model, the following baseline characteristics were independently predictive of death: greater dysfunction on a scale of intermediate activities of daily living, male gender, living alone, white race, better quality of social interactions, and age. Initial baseline functional measures were also predictive of follow-up health status perceptions. CONCLUSION The assessment of information on physical functioning and the quality of social interactions provides prognostic information regarding mortality. Furthermore, of the independent predictors of death identified in this sample, only functional impairment and living alone are remediable. Whether improving functional status can reduce the risk of mortality remains to be determined.

Abstract
OBJECTIVES Health maintenance organizations (HMOs) continue to grow in number and in their enrollment of Medicare recipients. They are also increasingly viewed as organizational structures that might contribute to control of health care costs. Yet little is known about the quality of care that elderly HMO enrollees receive. METHODS We compared patients from three HMOs to a fee-for-service (FFS) sample that was national in scope. Sickness at admission, the quality of process of care, and mortality were assessed for patients aged 65 years and older who had been hospitalized with a diagnosis of acute myocardial infarction. RESULTS After adjustment for sickness at admission, there were no significant mortality differences between the HMO and FFS groups at either 30 (23.2% vs 23.5%) or 180 days (34.4% vs 34.5%) after admission. Compliance with process criteria was higher for the HMO group as a whole (P < .05). The HMOs had greater compliance with three of five scales measuring different aspects of care for patients with acute myocardial infarction. CONCLUSIONS We conclude that older patients from our participating HMOs who were hospitalized for acute myocardial infarction received hospital care that was generally better in terms of process than that received by patients in a national FFS sample.

Abstract
OBJECTIVE To analyze whether important gender differences exist in the quality of hospital care provided to patients with four major medical conditions. DESIGN Bivariate and multivariate comparisons of clinically detailed sickness at admission, quality, utilization, and outcome measures. SETTING Acute care hospitals located in five states. PATIENTS OR OTHER PARTICIPANTS A total of 11,242 patients 65 years or older who were hospitalized with one of four diseases: congestive heart failure, acute myocardial infarction, pneumonia, and cerebrovascular accident. We derived our data from the nationally representative sample used to study the quality of hospital care for Medicare patients before and after the implementation of the prospective payment system. A hierarchical (nested) cluster sampling design was used to draw disease-specific samples of patients hospitalized in 1981, 1982, 1985, or 1986 in one of 297 hospitals located in 30 areas within five states. INTERVENTIONS This was an observational study. MAIN OUTCOME MEASURES Sickness at admission, process, use rates, length of stay, discharge status, discharge destination, and mortality. RESULTS Sex differences in sickness at admission varied by disease. There was some evidence that women received worse process of care, but the difference was very small. We found many similarities in the process and outcomes of care for male and female patients. CONCLUSIONS After controlling for sickness at admission, age, and other important covariates, the in-hospital experiences of elderly men and women showed greater similarities than differences. The concern that sex bias enters into clinical decision making during hospitalization is eased, although not entirely eliminated.

Abstract
OBJECTIVE To compare quality of care measured by explicit criteria, implicit review, and sickness-adjusted outcomes at different types of hospitals. DESIGN Further analysis of data retrospectively abstracted from medical records to evaluate the effects of prospective payment on quality of care for hospitalized Medicare patients. SETTING Hospitals in five states were sampled to represent the national Medicare admissions along many dimensions. PATIENTS A total of 14,008 elderly patients with one of the following five diseases: congestive heart failure, acute myocardial infarction, pneumonia, stroke, or hip fracture. These patients were randomly sampled from those with these diseases in 297 hospitals in two time periods, 1981 to 1982 and 1985 to 1986. OUTCOME MEASURES Explicit criteria, implicit review, and mortality within 30 days of admission adjusted for sickness at admission. RESULTS Quality of care ratings for hospital types are similar using explicit criteria, implicit review, and outcomes adjusted for sickness at admission. Quality differences between types of hospitals were large, with the lowest group estimated to have four percentage points higher mortality than major teaching hospitals in a cohort of patients with average mortality of 16%. Quality varies from state to state, but teaching, larger, and more urban hospitals have better quality in general than nonteaching, small, and rural hospitals. Hospital quality persists over time, but small nonteaching hospitals narrowed the gap with better quality hospitals between 1981 and 1986. CONCLUSIONS The different measures led to consistent and plausible relationships between quality and hospital characteristics. Thus, valid information about hospital quality can be obtained. We need to develop ways to use such information to improve care.

Abstract
OBJECTIVE To determine how well one state's peer review organization (PRO) judged the quality of hospital care compared with an independent, credible judgment of quality of care. DESIGN Retrospective study comparing a PRO's review, including initial screening, physician review, and final judgments, with an independent "study judgment" based on blinded, structured, implicit reviews of hospital records. SETTING One state's medical and surgical Medicare hospitalizations during 1985 through 1987 audited randomly by the state's PRO. SAMPLE Stratified random sampling of records: 62 records that passed the PRO initial screening process and were not referred for PRO physician review; 50 records that failed the PRO screen and then were confirmed by PRO physicians to be "quality problems." INTERVENTION None. MAIN OUTCOME MEASURE A study judgment of below standard or standard or above based on the mean of overall ratings by five internists for records in medical diagnosis related groups (DRGs) and by five internists and five surgeons for surgical DRGs. Each step in the PRO review was evaluated for how many records passing or failing that step were judged standard or above or below standard in the study (positive and negative predictive value) and how well that step classified records that the study judged below standard or standard or above (sensitivity and specificity). RESULTS An estimated 18% of records reviewed by the PRO were below standard according to the study judgment, compared with 6.3% quality problems according to the PRO's final judgment (difference, 12%; 95% confidence interval, 1 to 23). The PRO's initial screening process failed to detect and refer for PRO physician review two of three records that the study judged below standard. In addition, only one of three of the records that PRO physicians judged to be quality problems were judged below standard by the study judgment. Therefore, the PRO's final quality of care judgment and the study judgment agreed little more than expected by chance, especially about poor quality of care. Although the PRO correctly classified 95% of the records that the study judged standard or above, it detected only 11% of records judged below standard by the study. CONCLUSIONS Most of all, this PRO review process would be improved by additional preliminary screens to identify the 67% of records that the study judged below standard but that passed its initial screening. The screening process also must be more accurate in order to be cost-effective, as it was only slightly better than random sampling at correctly identifying below standard care. More reproducible physician review is also needed and might be accomplished through improved reviewer selection and training, a structured review method, and more physician reviewers per record.

Abstract
OBJECTIVE To assess the ability of internists to identify functional disabilities reported by their patients. DESIGN Comparison of responses by physicians and a random sample of their patients to a 12-item questionnaire about physical and social function. SETTING A hospital-based internal medicine group practice in Boston, Massachusetts, and selected office-based internal medicine practices in Los Angeles, California. SUBJECTS Five staff physicians, three general internal medicine fellows, and 34 internal medicine residents in the hospital-based practice and 178 of their patients. Seventy-six physicians in the office-based practices and 230 of their patients. MEASUREMENTS AND MAIN RESULTS Physicians underestimated or failed to recognize 66% of disabilities reported by patients. Patient-reported disabilities were underestimated or unrecognized more often in the hospital-based practice than in the office-based practices (75% compared with 60%, P less than 0.05). Physicians overstated functional impairment in 21% of paired responses in which patients reported no disability. CONCLUSIONS Physicians often underestimate or fail to recognize functional disabilities that are reported by their patients. They overstate functional impairment to a lesser degree. Because these discrepancies may adversely affect patient care and well-being, medical educators and clinicians should pay more attention to the assessment of patient function.

Abstract
We developed explicit process criteria and scales for Medicare patients hospitalized with congestive heart failure, myocardial infarction, pneumonia, cerebrovascular accident, and hip fracture. We applied the process scales to a nationally representative sample of 14,012 patients hospitalized before and after the implementation of the diagnosis related group-based prospective payment system. For the four medical diseases, a better process of care resulted in lower mortality rates 30 days after admission. Patients in the upper quartile of process scores had a 30-day mortality rate 5% lower than that of patients in the lower quartile. The process of care improved after the introduction of the prospective payment system; eg, better nursing care after the introduction of the prospective payment system was associated with an expected decrease in 30-day mortality rates in pneumonia patients of 0.8 percentage points, and better physician cognitive performance was associated with an expected decrease in 30-day mortality rates of 0.4 percentage points. Overall, process improvements across all four medical conditions were associated with a 1 percentage point reduction in 30-day mortality rates after the introduction of the prospective payment system.

Since the introduction of the prospective payment system (PPS), anecdotal evidence has accumulated that patients are leaving the hospital "quicker and sicker." We developed valid measures of discharge impairment and measured these levels in a nationally representative sample of patients with one of five conditions prior to and following the PPS implementation. Instability at discharge (important clinical problems usually first occurring prior to discharge) predicted the likelihood of postdischarge deaths. At 90 days postdischarge, 16% of patients discharged unstable were dead vs 10% of patients discharged stable. After the PPS introduction, instability increased primarily among patients discharged home. Prior to the PPS, 10% of patients discharged home were unstable; after the PPS was implemented, 15% were discharged unstable, a 43% relative change. Efforts to monitor the effect of this increase in discharge instability on health should be implemented.

Abstract
In 1985, we began a 4-year evaluation of the effects of the diagnosis related groups-based prospective payment system on quality of care for hospitalized Medicare patients. This article provides an overview of the study's background, aims, design, and methods. We used a clinically detailed review of the medical record supplemented by data on postdischarge outcomes drawn from the files of the Health Care Financing Administration and fiscal intermediaries to (1) compare outcomes of care after adjustment for sickness at admission, (2) assess the process of in-hospital care and relationships between processes and outcomes, and (3) assess status at discharge for a nationally representative sample of patients hospitalized before and after prospective payment was implemented.

Abstract
We developed disease-specific measures of sickness at admission based on medical record data to study mortality of Medicare patients with one of five conditions (congestive heart failure, acute myocardial infarction, cerebrovascular accident, pneumonia, and hip fracture). We collected an average of 73 sickness variables per disease, but our final sickness-at-admission scales use, on average, 19 variables. These scales are publicly available, and explain 25% of the variance in 30-day postadmission mortality for patients with acute myocardial infarction, pneumonia, or cerebrovascular accident. Sickness at admission increased following the introduction of the prospective payment system (PPS). For our five diseases combined, the 30-day mortality to be expected because of sickness at admission was 1.0% higher in the 1985-1986 period than in the 1981-1982 period (16.4% vs 15.4%), and the expected 180-day mortality was 1.6% higher (30.1% vs 28.5%). Studies of the effects of PPS on mortality must take this increase in sickness at admission into account.

Abstract
We compared patient outcomes before and after the introduction of the diagnosis related groups (DRG)-based prospective payment system (PPS) in a nationally representative sample of 14,012 Medicare patients hospitalized in 1981 through 1982 and 1985 through 1986 with one of five diseases. For the five diseases combined; length of stay dropped 24% and in-hospital mortality declined from 16.1% to 12.6% after the PPS was introduced (P less than .05). Thirty-day mortality adjusted for sickness at admission was 1.1% lower than before (16.5% pre-PPS, 15.4% post-PPS; P less than .05), and 180-day adjusted mortality was essentially unchanged at 29.6% pre-vs 29.0% post-PPS (P less than .05). For patients admitted to the hospital from home, 4% more patients were not discharged home post-PPS than pre-PPS (P less than .05), and an additional 1% of patients had prolonged nursing home stays (P less than .05). The introduction of the PPS was not associated with a worsening of outcome for hospitalized Medicare patients. However, because our post-PPS data are from 1985 and 1986, we recommend that clinical monitoring be maintained to ensure that changes in prospective payment do not negatively affect patient outcome.

Abstract
We measured quality of care before and after implementation of the prospective payment system. We developed a structured implicit review form and applied it to a sample of 1366 Medicare patients with congestive heart failure, acute myocardial infarction, pneumonia, cerebrovascular accident, or hip fracture who were hospitalized in 1981-1982 or 1985-1986. Very poor quality of care was associated with increased death rates 30 days after admission (17% with very good care died vs 30% with very poor care). The quality of medical care improved between 1981-1982 and 1985-1986 (from 25% receiving poor or very poor care to 12%), although more patients were judged to have been discharged too soon and in unstable condition (7% vs 4%). Except for discharge planning processes, the quality of hospital care has continued to improve for Medicare patients despite, or because of, the introduction of the prospective payment system with its accompanying professional review organization review.

Abstract
In this series we have described changes in the quality of care that have occurred in the treatment of hospitalized elderly Medicare patients with one of five conditions between 1981-1982 and 1985-1986. In this article we report on a mortality analysis, patient and hospital subgroup comparisons, and time series studies we have conducted in an attempt to determine whether changes in quality of care can be linked causally to the introduction of the prospective payment system. Based on these analyses we conclude that (1) mortality following hospitalization has been unaffected by the introduction of the prospective payment system, and improvements in in-hospital processes of care that began prior to the prospective payment system have continued after its introduction, but (2) the prospective payment system has increased the likelihood that a patient will be discharged home in an unstable condition. We recommend that efforts to correct this problem be intensified and that clinical monitoring of the impact of the prospective payment system continue as hospital cost-containment pressures intensify.

Abstract
STUDY OBJECTIVES To test whether a 34-item functional status questionnaire measuring physical, psychological, and social function can be used by physicians in practice to help improve their patients' outcomes. DESIGN Prospective randomized trial. SETTING Community internal medicine practices. PATIENTS Five hundred and ten continuing patients with functional disabilities who saw their physicians at least four times a year. PHYSICIANS: Seventy-six UCLA clinical volunteer faculty who are internists in community office practices. INTERVENTIONS Physicians and their patients were randomly assigned to the experimental or the control group. Experimental group physicians attended a 2-hour multimedia educational session and received four functional status reports on each of their study patients over a 1-year period. Control group physicians received no education and no functional status feedback. Control group and experimental group patients were tested for functional status with the functional status questionnaire every 4 months for 1 year. Both groups also completed monthly diaries that measured use of health services. Experimental group physicians answered an anonymous evaluation questionnaire at 6 months after study entry. MEASUREMENTS AND MAIN RESULTS Forty-three percent of experimental group physicians reported that they had used the functional status questionnaire to change therapy. Ninety-five percent reported that it was useful and accurate. Patient diaries did not show any difference between experimental group patients and control group patients in number of medications used, visits to physicians or other health professionals, equipment purchased, diet, or exercise programs. There were no significant differences between experimental and control group patients at exit from the study on any functional status or health outcome measure. CONCLUSION A more powerful intervention than a 2-hour educational session and the regular provision of functional status information is needed to help office-based internists improve patient outcomes.

Abstract
A comprehensive functional assessment requires thorough and careful inquiry, which is difficult to accomplish in most busy clinical practices. This paper examines the reliability and validity of the Functional Status Questionnaire (FSQ), a brief, standardized, self-administered questionnaire designed to provide a comprehensive and feasible assessment of physical, psychological, social and role function in ambulatory patients. The FSQ can be completed and computer-scored in minutes to produce a one-page report which includes six summated-rating scale scores and six single-item scores. The clinician can use this report both to screen for and to monitor patients' functional status. In this study, the FSQ was administered to 497 regular users of Boston's Beth Israel Hospital's Healthcare Associates and 656 regular users of 76 internal medicine practices in Los Angeles. The data demonstrate that the FSQ produces reliable sub-scales with construct validity. The authors believe the FSQ addresses many of the problems behind the slow diffusion into primary care of systematic functional assessment.

Abstract
The serum alkaline phosphatase (ALP) is often included among the tests used for case-finding among ambulatory patients. To determine the positive predictive value of the ALP, test results for all adults screened by a health maintenance organization between March and December 1969 were obtained by computer. The authors reviewed the charts of all 661 patients with abnormal tests whose primary source of medical care was at this facility. Complete two-year follow-up data were available for 91% of these patients. There were 56 patients (9%) with a diagnosis that could have explained an abnormal ALP. Of those cases in which ALP would have been clinically useful all but one could have been diagnosed by a simple, noninvasive workup, and in that one case, no management change would have occurred. The authors conclude that in the absence of a small number of specific indications, extensive testing need not be performed to evaluate an isolated abnormal ALP obtained from a screening examination.

Abstract
Several studies have concluded that specialists form a hidden system for primary-care delivery. However, these studies assume that a specialist who provides the majority of care is the primary-care physician. Using data for a one-year period from 2752 people enrolled in the Rand Health Insurance Experiment, we examined the validity of this conclusion. We compared the effects of three different definitions of a primary-care physician on identification of the primary-care provider: the physician who delivered the "majority of care" (34 per cent were specialists), the physician designated by the patient to receive the results of a multiphasic-screening examination (12 per cent were specialists), and the physician who treated common problems (9 per cent were specialists). Use of the "majority-of-care" criterion to define primary care overestimated by threefold the contribution specialists make to this activity. Definitions of a primary-care physician must be more specific and should include the tasks frequently associated with primary care, as well as patients' perceptions of the physician who provides their primary care.
