Replication Data for: Clinical features and risk factors for pyogenic liver abscess caused by multidrug-resistant organisms: A retrospective study

Data were retrospectively collected from the case database of patients diagnosed with PLA who were admitted to Huashan Hospital in Shanghai, China, between June 1, 2012, and May 31, 2022. The study population consisted of patients aged 18–85 years, both male and female, who met the following diagnostic criteria: 1) presence of clinical manifestations, such as fever, chills, or abdominal pain; 2) imaging results such as abdominal ultrasound and/or computed tomography consistent with the imaging characteristics of liver abscesses; 3) confirmation of pathogenic bacteria by blood culture, pus culture, or metagenomic next-generation sequencing (mNGS); and 4) confirmation of an abscess by percutaneous liver biopsy or surgery. Patients with amoebic or tuberculous liver abscesses or incomplete clinical data were excluded. Data were extracted from patient medical records stored in the electronic medical record system. The data included demographic characteristics (sex, age, body mass index), clinical manifestations (temperature, fever, chills, gastrointestinal symptoms, state of consciousness), underlying diseases (hypertension, diabetes, chronic lung disease, cardiovascular and cerebrovascular diseases, cirrhosis, malignant tumors, chronic renal insufficiency, history of hormone or immunosuppressant use), laboratory test results (hematologic, biochemical, and microbiologic test results), liver imaging results (abscess diameter, location, quantity, separation, presence or absence of gas in the liver), dissemination of infection (to the lung, spleen, brain, skin, or eye), treatment during hospitalization (antibiotic use, percutaneous liver puncture drainage, surgery), and outcome at discharge (recovery or death).
