Measuring Students' Workload
Despite 70 years of studies of the effect of students' outside work on their academic performance, the measurement of students' workload has received little attention. Three alternative measures of workload, one of which included credit loads, were assessed and compared for a sample of 128 college students. The means of these measures varied widely, but the measures were highly intercorrelated and produced equivalent correlations with academic pe…
USMGs Versus FMGs
Several earlier studies compared performance differences between USMGs and FMGs in inpatient care settings, mainly hospitals. This study compares performance differences between USMGs and FMGs in ambulatory care settings. The sample consisted of 14,203 patient episodes treated by 1,156 physicians (pediatricians, obstetricians/gynecologists, internists, and other specialty physicians). The study setting was a midwestern state. Little evidence was …
Problems of case finding and data collection in ambulatory care settings
The experience gained in a four-year ambulatory care study suggests that major problems of patient care data collection include: 1) Difficulties in obtaining listings of patients by diagnosis/condition that accurately reflect the actual practice experience; 2) Inaccurate coding or identification of the reason for patient visits; and 3) Inability to find the medical record within the system. Data presented here suggest there are certain regulariti…

Patient Race and Physician Performances
The study has attempted to determine the extent of the relationship between patient race and physicians' performances in patient care. The sample of the study consisted of 3175 hospital episode of patients discharged from 22 short-term general hospitals in the state of Hawaii. The episodes were derived from 15 major diagnostic categories. Physicians performances were measured on the basis of the quality of medical care provided, the appropriatene…
Interrelationships of Physician Performances
The study determined the intrarelationships and interrelationships of two sets of physician performance measures: technical quality and utilization of medical resources. The performance measures were based on 2,431 episodes in 15 diagnostic categories involving 454 physicians. A series of correlations were used to determine these relationships. The technical performance of physicians for prehospitalization, hospitalization, and posthospitalizatio…
Interdiagnosis Relationships of Physician Performance Measures in Hospitals
Correlations among ten diagnostic categories of hospital care physican performance measures are reported. Using measures of conformance to predetermined criteria for optimal performance, mean scores of individual physican performances within diagnostic categories were calculated and correlated. Measurement reliability estimates were computed and it was suggested that a minimum of four cases in each diagnostic category be used for measurement of p…
Patient responses to request for written permission to review medical records
2,163 patients of 55 physicians in one county, were sent letters asking for their written permission to have their medical records audited by the University of Michigan research team. The overall positive response rate was 64.1% for one county. Differences in response rates were statistically significant among specialties, among diagnoses, and among individual physicians
The Use of Item Importance Weights in Assessing Physician Performance with Predetermined Criteria Indices
Conditions for using single measures or combinations of measures of physician performance are discussed. Studies reporting combination indices of proficiency are reviewed for their use of equally or differentially weighted components and for the use of these with many or with single diagnoses, Comparisons of diagnostic-specific measures are made using differential and equal item weights. Under the general conditions of this research, few psychome…
The Relationship of Physicians?? Medical Recording Performance to Their Medical Care Performance
Within eight diagnostic categories on an individual case level of analysis, separate indices of recorded physician conformance to predetermined criteria for optimal care were derived. One index for each diagnosis was composed of measures that depended upon a physician's medical record recording and another was composed of measures recorded independently of the physician. Correlation coefficients between indices averaged +0.23 with a range from −0…
Interdiagnosis Relationships of Physician Performance Measures
The degrees of relationships among 13 diagnostic categories of office care performances of 93 primary care physicians are reported. Using conformance to predetermined criteria of optimal performance, mean scores of individual physician performances within diagnostic categories or conditions were computed and correlated. Overall, an average interdiagnostic correlation of +0.25 was obtained, with clusters of correlations apparent in the matrix. The…
