Objective: To review the literature and attempt to define patient comp
liance with hormonal replacement therapy and physician prescription of
these therapies. Design: Review of selected literature. Setting: Popu
lation studies and clinical trials. Patients: Postmenopausal and postc
astration women. Interventions: Hormone replacement regimens. Main Out
come Measures: Descriptions and compliance by patients. Results: In ad
dition to the effective control of vasomotor hot flushes and atrophic
genital changes in postmenopausal women, it is now well established th
at the long-term use of estrogen replacement therapy (ERT) or hormone
replacement therapy (HRT) with estrogen and/or progestin offers prophy
laxis against osteoporosis and cardiovascular arteriosclerotic disease
, notably myocardial infarction. However, despite such documentation o
f benefit, it is estimated that <20% of postmenopausal women in the Un
ited States have ever had ERT or HRT prescribed, <40% of those for who
m such treatment has been prescribed will continue it after 1 year, an
d that overall, >70% of those for whom it has been prescribed are not
compliant. It appears that this lack of prescription and compliance ar
e the function of both physician and patient considerations. This pape
r presents reasons for such actions and reviews ways in which use can
be improved.
