    • PROCEDURES_ICD.csv: the procedure file from MIMIC-III raw dataset
    • RXCUI2atc4.csv: this is a NDC-RXCUI-ATC4 mapping file, and we only need the RXCUI to ATC4 mapping. This file is obtained from https://github.com/ycq091044/SafeDrug.
    • drug-atc.csv: this is a CID-ATC file, which gives the mapping from CID code to detailed ATC code (we will use the prefix of the ATC code latter for aggregation). This file is obtained from https://github.com/ycq091044/SafeDrug.

    • drugbank_drugs_info.csv: drug information table downloaded from drugbank here https://www.dropbox.com/s/angoirabxurjljh/drugbank_drugs_info.csv?dl=0, which is used to map drug name to drug SMILES string.
    • drug-DDI.csv: this a large file, containing the drug DDI information, coded by CID. The file could be downloaded from https://drive.google.com/file/d/1mnPc0O0ztz0fkv3HF-dpmBb8PLWsEoDz/view?usp=sharing

After the processing have been done, we get the following statistics:

# patients  6350
# clinical events  15032
# diagnosis  1958
# med  112
# procedure 1430
# avg of diagnoses  10.5089143161256

• First, install the rdkit (RDKit: Open-Source Cheminformatics Software) conda environment

  conda create -c conda-forge -n SafeDrug rdkit
  conda activate SafeDrug

• Clone this repository in your preferred location. We assume that you clone it in your home directory.

  cd ~
  git clone [email protected]:samhq/cs598dl4h-project.git 

• In SafeDrug environment, run the following commands to install required python packages (according to your GPU support)

  cd ~/cs598dl4h-project
  
  # if you don't have GPU
  ./dependency.sh
  
  # if you have GPU
  ./dependency.sh 1

• Go to https://physionet.org/content/mimiciii/1.4/ to download the MIMIC-III dataset (You may need to get the certificate)

  wget -r -N -c -np --user [account] --ask-password https://physionet.org/files/mimiciii/1.4/

• Go into the folder and unzip required three files and copy them to the ~/cs598dl4h-project/data/input/ folder

  cd ~/physionet.org/files/mimiciii/1.4
  gzip -d PROCEDURES_ICD.csv.gz # procedure information
  gzip -d PRESCRIPTIONS.csv.gz  # prescription information
  gzip -d DIAGNOSES_ICD.csv.gz  # diagnosis information
  cp PROCEDURES_ICD.csv PRESCRIPTIONS.csv DIAGNOSES_ICD.csv ~/cs598dl4h-project/data/input/

• Download additional files in the ~/cs598dl4h-project/data/input/ folder

  cd ~/cs598dl4h-project/data/input/
  ./get_additional_files.sh

• Processing the data to get a complete records_final.pkl

  cd ~/cs598dl4h-project/data
  python processing.py

To run the SafeDrug model, run the following:

cd ~/cs598dl4h-project/src
python SafeDrug.py

here is the argument:

usage: SafeDrug.py [-h] [--Test] [--model_name=MODEL_NAME]
               [--resume_path=RESUME_PATH] [--lr=LR]
               [--target_ddi=TARGET_DDI] [--kp=KP] [--dim=DIM]
               [--epoch=EPOCH]

optional arguments:
  -h, --help                  show this help message and exit
  --Test                      test mode
  --model_name MODEL_NAME     model name
  --resume_path RESUME_PATH   resume path
  --lr LR                     learning rate
  --target_ddi TARGET_DDI     target ddi
  --kp KP                     coefficient of P signal
  --dim DIM                   dimension
  --epoch EPOCH               how many epoch

If you want to run all models consecutively, then run:

cd ~/cs598dl4h-project/src
./run_models.sh [NUMBER_OF_EPOCHS]
