STANKOVSKI, Vlado, SMRKE, Dragica. Hierarchical decision model for the patient's
long term clinical status after hip arthroplasty. Med. biol. eng.

objective of this research was to buils a model to determine the patient'slong
term clinical status following and implantation of hip endoprosthesis. Medical
records of patients treated for acute medial femoral neck fractures with hip
endoprosthesis were analyzed. The long term clinical status of the patients
several years after the hip arthroplasty was determinedusing the Hariis hip
score. The factors were organized into sementically meaningful groups, and for
each group an intermediate factor was introduced by an expert. Several levels of
intermediate factors were defined, resulting in a hierarchiacal decision model
having Harris hip score (the outcome) at its root. The modeling process was
supported by the multyattributedecision support system DEX. The hierarchical
model takes into account many different factors that influence the patient's
long term clinicalstatus after hip arthroplasty. The particular approach
propose, which combines expert's knowledge and completes the model by industion
from data, was found beneficial. Following are most important factors in terms
of their influence to Hariis hip score: patient's status before injury, the
timing of operation, and the type of endoprosthesis (in this order).
