Abstract

OBJECTIVES:

To describe national trends in the practice of radical nephrectomy (RN) in England between 1995 and 2002.

METHODS:

Data were extracted from the Hospital Episode Statistics database of the Department of Health in England between 1995/1996 and 2001/2002. Patients were included in the study if an International Classification of Diseases diagnosis code (ICD-10) for malignant neoplasm of the kidney, renal pelvis or ureter, and an operative procedure code (OPCS-4) describing total or partial excision of the kidney by either a laparoscopic or open approach, were present in any of the diagnosis or operative procedure fields. Overall, 17 308 patients were included.

RESULTS:

Patient age and the proportion who were men did not change over the study period. The proportion of patients admitted as an emergency decreased from 14.0% to 7.5% over this period (P < 0.001). The mean waiting duration increased by almost 6 days (P < 0.001) and length of stay by approximately 1 day, from 11.7 days in 1995 to 10.8 days in 2001 (P < 0.001). In-hospital mortality decreased from 2% to 1.5% (P = 0.134). In-hospital mortality and length of stay were higher in older patients and in those admitted as an emergency. Women had a longer stay than men (11.5 vs 11.1 days), but in-hospital mortality was higher in men (2.3% vs 1.6%). The national number of RNs per year increased by approximately 20%, from 2254 in 1995 to 2671 in 2001. Over the same period the mean annual hospital volume of RN increased by approximately 40%, from 17 in 1995 to 24 in 2001. The annual number of laparoscopic RNs nationally increased from seven in 1995 to 84 in 2002.

CONCLUSIONS:

The annual number of RNs in England increased by almost a fifth and this was accompanied by an increase in annual hospital volume of about two-fifths. There was a large proportional increase in the number of laparoscopic RNs. Emergency admission rates and length of stay decreased but this was not accompanied by a significant change in in-hospital mortality rate.
