BACKGROUND The present study investigated the effects of Quercus infectoria (QI) gall extract on the proliferation, alkaline phosphatase (ALP), osteocalcin, and the morphology of a human fetal osteoblast cell line (hFOB 1.19). METHODS The cells were cultured in Dulbecco's modified eagle medium F12 supplemented with a 10% fetal bovine serum, a 1% penicillin/streptomycin and were treated with Q...

This article presents a systematic review of the research methods used to study quality improvement (QI) effectiveness in health care organizations. The review relied on existing literature as well as emergent themes to identify types of QI programs (e.g., data/feedback, information technology, staff education) and quality outcomes (e.g., mortality, morbidity, unnecessary variation). Studies we...

Five years after the Institute of Medicine (IOM) called for a redesigned U.S. health care system, relatively little was known about the extent to which hospitals had undertaken quality improvement (QI) efforts to address deficiencies in patient care. To examine the state of hospital QI activities in 2006, the authors designed and conducted a survey of short-term, general hospitals with 25 or mo...

For any two consecutive Farey fractions γi = ai/qi < γi+1 = ai+1/qi+1, one has ai+1qi − aiqi+1 = 1 and qi + qi+1 > Q. Conversely, if q and q ′ are two coprime integers in {1, . . . , Q} with q + q > Q, then there are unique a ∈ {1, . . . , q} and a ∈ {1, . . . , q} for which aq − aq = 1, and a/q < a/q are consecutive Farey fractions of order Q. Therefore, the pairs of coprime integers (q, q) wi...

Education in patient safety (PS) and quality improvement (QI) helps both medical students and residents understand the health care environment in the United States, where these concepts are now incorporated into virtually every aspect of patient care. The Accreditation Council of Graduate Medical Education has made PS/QI a mandatory component of resident education, and a number of specialties h...

Effective quality improvement (QI) education should improve patient care, but many curriculum studies do not include clinical measures. The research team evaluated the prevalence of QI curricula with clinical measures and their association with several curricular features. MEDLINE, Embase, CINAHL, and ERIC were searched through December 31, 2013. Study selection and data extraction were complet...

INTRODUCTION As health systems find ways to improve quality of care, medical training programs are finding opportunities to prepare learners on principles of quality improvement (QI). The impact of QI curricula for medical students as measured by student learning is not well delineated. The aim of this study is to evaluate the effectiveness of a QI curriculum for senior medical students as meas...
