The cost of hospital stay for operable breast cancer.

The cost of the first hospital stay for operable breast cancer was deducted by analysing a random sample of 100 admissions to the National Institute of Cancer during the period January-December 1989. The aims of the study were: (1) to describe and calculate the cost component of the stay; (2) to analyse whether any procedure, service rendered or stage of the pathology might explain differences in the total costs of the stay; and (3) to acquire a better knowledge of the organizational aspects to be improved. With an average length of stay of 14.1 days, the overall total cost observed was 4.9 million lira (US $3.800, 1989 US dollars). A significant correlation between total cost and duration of stay was found (R2 = 0.982), while no or very little correlation was found between cost and the anatomical extent of disease (TNM stage) and different cost items (laboratory, imaging tests, operating room, etc.). Two homogeneous groups of cases were found: patients with quadrantectomy and patients with mastectomy. The cost of the latter was 40% greater than that of the former (P < 0.001) with a length of stay 52% longer (p < 0.001). This study does not concern the costs immediately following the stay, which namely are higher for the quadrantectomy because the radiotherapy outpatient procedures. Attention should be paid to reducing the length of stay, keeping waiting time for organizational procedures to a minimum during the stay.
