文章先对《黄帝内经》中肾为欠、为嚏进行探讨,并在实践中得到体悟。进一步认识到人体是一个整体,五脏六腑互联互动,互为表达,也就是五行生克关系。五行学说是中医理论的重要组成部分,活学活用五行学说,才能以我知彼,以表知里,以观过与不及之理,见微得过,用之不殆。 相似文献

A voluntary organisation providing family support and mental health services carried out an enquiry into the feasibility of setting up placements in primary care for students from professional qualifying courses in community nursing, social work and occupational therapy to experience shared practice learning in their placement. Consultation with a range of courses from two universities in London and with GP practices and other primary care agencies in East London established that there was wide support for the idea from practitioners, managers and academic teachers. It was recommended that a small number of pilot placements be set up. It was acknowledged that the diversity of placement requirements across the spectrum of professional education is a limiting factor in bringing students together for practice learning. The authors suggest that in the longer term, the development of an interprofessional approach to practice learning will require structural changes to professional courses so as to bring their placement requirements more into line with each other. 相似文献

Objective - To try out a collection of a standard set of data from computerised medical records. Design - Retrospective extraction of ordinary patient record information put into the computer by general practitioners. Setting - Encounters in office hours in strategically selected practices or health centres in Denmark, Finland, Iceland, Norway and Sweden. Subjects - 59 general practitioners and a total study population of 97475 persons. Main outcome measures - Proportions, crude and specific rates of encounters, diagnoses and processes. Results - In a 4-week period there was a threefold difference in the office encounter rates between the participating sites in the Nordic countries. Gender and age patterns were similar despite these differ ences. An access to several different denominators revealed diverse patterns of referring to the specialist, prescribing, ordering blood tests, X-rays and physiotherapy. Data from computerised medical records agree well with earlier studies in the Nordic countries using other methods. Conclusions - This survey demonstrates that valid and reliable data for routine statistics are available from computerised medical records in general practice. The major obstacle extracting more epidemiological data from computerised medical records is caused by information in the databases not being uniquely linked to episodes of care. 相似文献

Summary A United States-specific cost-effectiveness analysis, which incorporated the cost and health consequences of clinical fractures
of the hip, spine, forearm, shoulder, rib, pelvis and lower leg, was undertaken to identify the 10-year hip fracture probability
required for osteoporosis treatment to be cost-effective for cohorts defined by age, sex, and race/ethnicity. A 3% 10-year
risk of hip fracture was generally required for osteoporosis treatment to cost less than $60,000 per QALY gained.
Introduction Rapid growth of the elderly United States population will result in so many at risk of osteoporosis that economically efficient
approaches to osteoporosis care warrant consideration.
Methods A Markov-cohort model of annual United States age-specific incidence of clinical hip, spine, forearm, shoulder, rib, pelvis
and lower leg fractures, costs (2005 US dollars), and quality-adjusted life years (QALYs) was used to assess the cost-effectiveness
of osteoporosis treatment ($600/yr drug cost for 5 years with 35% fracture reduction) by gender and race/ethnicity groups.
To determine the 10-year hip fracture probability at which treatment became cost-effective, average annual age-specific probabilities
for all fractures were multiplied by a relative risk (RR) that was systematically varied from 0 to 10 until a cost of $60,000
per QALY gained was observed for treatment relative to no intervention.
Results Osteoporosis treatment was cost-effective when the 10-year hip fracture probability reached approximately 3%. Although the
RR at which treatment became cost-effective varied markedly between genders and by race/ethnicity, the absolute 10-year hip
fracture probability at which intervention became cost-effective was similar across race/ethnicity groups, but tended to be
slightly higher for men than for women.
Conclusions Application of the WHO risk prediction algorithm to identify individuals with a 3% 10-year hip fracture probability may facilitate
efficient osteoporosis treatment.
