Other non-significant covariates entered in the model: gender, institution's technical competency (bone marrow biopsy or aspiration, Ph + chromosome testing), number of physicians, WHO region.
Randomizing patients to physicians, and having multiple physicians rate the same randomly-assigned patient, would offer a stronger test of physician-level influences on GAF scores.
This may be due to there being fewer barriers to testing and ready accessibility of hyperlipidemia lab testing to physicians of all specialties, in contrast to other services such as DXA and colonoscopy which require access to special equipment or physicians with specialized training in performing this procedure.
Fewer family physicians considered that they should perform faecal occult blood tests (84% of physicians), evaluation of PSA (63%) and the digital rectal examination (66%).
Other potential attributes to the increase in mortality during off-hours are availability of skilled staff in the cardiac care unit, availability of diagnostic tests, number of physicians or nursing staff, and human factors such as sleep deprivation and fatigue.
In the absence of a gold standard to measure health information gap, examining women's choice of the delivery mode by SES may be useful in empirical testing of the physician-induced demand hypothesis.
We tested number of physician visits but the US was missing one-third of the years of observations.
We used six multivariate logistic regression models that show the association between sick leave status and various socio-demographic characteristics with each of the cancer tests, number of physician visits, and whether members saw a doctor during the prior year.
A second alternative, initially proposed by one of our co-authors, [ 20] is to rank order t-test values of physician efficiency measures and use a percentile cut-off (e.g. 20%) of this t-test distribution.
It was first used in a pilot test of ten physicians participating in the Witten/ Herdecke Universitys quality circle.
