Monitoring compliance with transfusion guidelines in hospital departments by electronic data capture.

BACKGROUND: The practice of transfusing red blood cells is still liberal in some centres suggesting a lack of compliance with guidelines recommending transfusion of red blood cells at haemoglobin levels of 6-8 g/dL in the non-bleeding patient. Few databases provide ongoing feedback of data on pre-transfusion haemoglobin levels at the departmental level. In a tertiary care hospital, no such data were produced before this study. Our aim was to establish a Patient Blood Management database based on electronic data capture in order to monitor compliance with transfusion guidelines at departmental and hospital levels. MATERIALS AND METHODS: Hospital data on admissions, diagnoses and surgical procedures were used to define the populations of patients. Data on haemoglobin measurements and red blood cell transfusions were used to calculate pre-transfusion haemoglobin, percentage of transfused patients and transfusion volumes. RESULTS: The model dataset include 33,587 admissions, of which 10% had received at least one unit of red blood cells. Haemoglobin measurements preceded 96.7% of the units transfused. The median pre-transfusion haemoglobin was 8.9 g/dL (interquartile range 8.2-9.7) at the hospital level. In only 6.5% of the cases, transfusion was initiated at 7.3 g/dL or lower as recommended by the Danish national transfusion guideline. In 27% of the cases, transfusion was initiated when the haemoglobin level was 9.3 g/dL or higher, which is not recommended. A median of two units was transfused per transfusion episode and per hospital admission. Transfusion practice was more liberal in surgical and intensive care units than in medical departments. DISCUSSION: We described pre-transfusion haemoglobin levels, transfusion rates and volumes at hospital and departmental levels, and in surgical subpopulations. Initial data revealed an extensive liberal practice and low compliance with national transfusion guidelines, and identified wards in need of intervention.

Overall survival after immunotherapy, tyrosine kinase inhibitors and surgery in treatment of metastatic renal cell cancer: outcome of 143 consecutive patients from a single centre.

OBJECTIVE: The aim of this study was to evaluate overall survival (OS) after treatment of metastatic renal cell carcinoma (mRCC) following the introduction of tyrosine kinase inhibitors (TKIs) and mammalian target of rapamycin (mTOR) inhibitors. MATERIAL AND METHODS: One-hundred and forty-three consecutive mRCC patients were given immunotherapy (n = 59), TKIs (n = 49) or sequential therapy (IMM → TKI group; n = 35). The TKI group included patients with higher age (p < 0.001), worse performance status (p = 0.005) and higher risk profile (p < 0.001) than the other two treatment groups. Number of metastases and sites and tumour histology did not differ between groups. RESULTS: First line immunotherapy gave a median OS of 16.3 months and first line TKIs 10.9 months (p = 0.003). Survival longer than 5 years was limited to immunotherapy. Sarcomatoid component, metastatic sites, papillary histology, stage, performance status and white cell blood count were related to poor OS. Using multivariate analyses to adjust for risk predictors the difference in OS disappeared. Median OS before and after introduction of TKIs was 16 months and 14 months, respectively (p = 0.189). Memorial Sloan Kettering Cancer Center (MSKCC) risk groups were related to OS (p < 0.001). Heng's prognostic criteria appeared slightly more predictive than MSKCC (p = 0.12). Metastasectomy (n = 42) may improve OS [surgery: median OS 18.8 months, 95% confidence interval (CI) 12.3-48.5; no surgery: median OS 15 months, 95% CI 10.4-16.5; p = 0.07]. CONCLUSIONS: MSKCC and Heng's prognostic algorithms were valid for prognostication and can be used for individual planning of treatment and follow-up. Surgical removal of metastases may improve OS.
