The invention relates to the technical field of medical
data processing, in particular to a
postmenopausal osteoporosis patient medical
data analysis method and
system, and the method comprises the following steps: extracting a
bone mineral density measurement value and a bone
metabolism index concentration based on patient
bone mineral density data, bone
metabolism index data and fracture event records; according to the method, through combination of
covariance matrix calculation, feature value and
feature vector extraction and revealing of deep relevance between data, fine description of
bone mineral density and
metabolism index changes is achieved, state probability values, fracture records and
drug use data are subjected to normalization weighting
processing, and an optimized posterior
state distribution matrix is generated; the accuracy and comprehensiveness of data fusion are improved, a key
dynamic feature set is extracted through screening and accumulation operation, the pertinence and efficiency of analysis and normalization and time
interval prediction of a trend curve are optimized, a
quantitative result of the bone
mineral density change trend and the
fracture risk is formed, and high-precision support is provided for illness state assessment and personalized analysis.
