          ABSTRACT    OBJECTIVE  To  explore  the  predictive  factors  of  cefoperazone/sulbactam-induced  thrombocytopenia  in  adult
          inpatients,  and  to  establish  and  validate  the  nomogram  prediction  model.  METHODS  Data  of  adult  inpatients  treated  with
          cefoperazone/sulbactam  in  Xi’an  Central  Hospital  from  Jun.  30th,  2021  to  Jun.  30th,  2023  were  retrospectively  collected.  The
          training  set  and  internal  validation  set  were  randomly  constructed  in  a  7∶3  ratio.  Singler  factor  and  multifactor  Logistic  regression
          analysis  were  used  to  screen  the  independent  predictors  of  cefoperazone/sulbactam-induced  thrombocytopenia.  The  nomogram  was
          drawn  by  using “RMS”  of  R  4.0.3  software,  and  the  predictive  performance  of  the  model  was  evaluated  by  the  receiver  operating
          characteristic  curve  and  C-index  curve.  Hosmer-Lemeshow  goodness-of-fit  test  was  used  to  evaluate  the  calibration  degree  of  the
          model. Using the same standard, the clinical data of hospitalized patients receiving cefoperazone/sulbactam in Xi’an First Hospital
          in the same period were collected for external validation of the nomogram prediction model. RESULTS A total of 1 045 patients in
          Xi’an  Central  Hospital  were  included  in  this  study,  among  which  67  patients  suffered  from  cefoperazone/sulbactam-induced
                                                              thrombocytopenia,  with  an  incidence  of  6.41%. After  the  false
