PAC – post-acute care LOS – length of hospital stay (measured in days) n/a – not available or missing value
Patients' characteristics:
- id -- anonymised patient's identification number
- sex -- f - female; m - male
- age -- in years
- county -- county of residence
- Comorbidities. 19 disease categories, all binary variables (1 – disease, 0 – no disease):
- comorbidity -- Charlson comorbidity score

- congestive_heart_failure,
- peripheral_vascular_disease,
- cerebrovascular_disease,

- Fracture
- Time
- date_of_fracture -- actually it is date of hospitalisation, but mostly they are the same
- year -- year of fracture
- Type
- fracture_type -- 3 values: femoral_neck, pertrochanteric, subtrochanteric
- Acute care (1st step care). Fracture treatment some variable include missing values (N/A) for operated patients
- operation_date
- days_to_operation – time from acute hospitalisation to operation in days
- operation_weekday – 1 – Monday, 2 Tuesday …
- management_method –values: conservative, hemiarthroplasty, total hip arthroplasty, osteosynthesis
- Length of stay and physical therapy received
- acute_LOS – integer variable, acute length of stay in days
- acute_therapy – scale variable, physical therapy received during acute care
- Post-acute care (2nd step care). Length of hospital stay
- post-acute_LOS – integer variable, total post-acute length of stay in days (includes all hospitalisations)
- post-acute_therapy – scale variable, total post-acute physical therapy received in hours (includes all in- and outpatient settings)
- PAC_type – post-acute care type: patients were subgrouped by received post-acute in- and outpatient care
- Survival. Variables presented as time (time period, m – month [in days or in months]) and status (1 – event of death occurred; 0 – alive at that time point). - time_3m - status_3m - time_12m - status_12m
- Patients' characteristics
- id -- anonymised patient's identification number
- invoice_number – post-acute invoices were numbered consecutively by date
- invoice_start – invoice start date
- invoice_end – invoice end date
- post-acute_type – type of setting (i simplified this part for the course, since defining these types would take much time)
- LOS – length of stay in days in this setting, zeros are for outpatient settings
- therapy – total physical therapy received in that setting
