Data on adjuvant therapies, including surgery (date of surgery, BCT, mastectomy, sentinel-node biopsy, and axillary lymph node dissection), adjuvant systemic chemotherapy, adjuvant endocrine therapy, and detailed information on administered adjuvant radiotherapy were also collected.
The initial model was then extended by adding information on administered medication, measurements of physiological parameters and laboratory results available during the first four hours of the patient's ICU stay.
On the day, due to an organisational error, vital information on administering the drug went missing and a consultant was not available to supervise the procedure.
The April 2013 report suggests that information on drugs administered in-hospital should be integrated in the PDR. 9 In Sweden, all health care is administered by 21 separate counties.
We did not have information on corticosteroids administered in hospital.
The system also contains information on medications administered intraoperatively, transfusions, airway management, and anesthetic technique.
Additionally, there was no information on drugs administered during inhospital care and no information on indication for treatment.
Governmental initiatives in both Norway and Sweden have been established with the aim of creating national databases, which include individual information on drugs administered in-hospital.
Using information on treatments administered within 1 year of diagnosis, cases were categorised by receipt of (1) 'cancer-directed' surgery (i.e. colon or rectal resection), (2) chemotherapy, or (3) radiotherapy.
In all, the electronic CRF comprised 385 items, to which was added information on medications administered before the index event, pre-hospital, during the first 24 and 48 h and at hospital discharge; for oral medications, doses were recorded.
Finally, since the DNPR does not contain information on drugs administered under hospitalization, we excluded patients with readmissions to any hospital (psychiatric or otherwise) during the first 30 days after discharge and before purchase of ADs (n = 10), resulting in a study population of 528 individuals (132 immigrants and 396 Danish-born residents), Figure 1.
