Initial management of low-risk localized prostate cancer in the UK: analysis of the British Association of Urological Surgeons Cancer Registry.

OBJECTIVE: to assess the patterns of care for low-risk localized prostate cancer. Management of this condition is highly controversial, with a range of treatment options, but there are no published UK data. METHODS: data from the British Association of Urological Surgeons (BAUS) Cancer Registry were linked to the UK Association of Cancer registries postcode directory. The demographic and clinical characteristics, and the initial management of men diagnosed with low-risk localized prostate cancer in the UK between 2000 and 2006 were analysed. RESULTS: In all, 43,322 cases of localized prostate cancer were recorded in the BAUS Registry between 2000 and 2006, of which 8861 (20%) met the criteria for low-risk disease. The proportion classified as low risk ranged from 16% in 2000 to 21% in 2006. The proportion of men with low-risk disease opting for 'watchful waiting' increased from 0% to 39% over the same period. Treatment choice was associated with socio-economic status. For example, radical prostatectomy was chosen by 34% of patients in the most affluent quintile, compared with 19% in the most deprived quintile (P= 0.01). CONCLUSION: the management of low-risk localized prostate cancer in the UK has changed markedly in recent years, and contrasts with that in the USA. The association observed between socio-economic status and choice of treatment deserves further study.

A description of radical nephrectomy practice and outcomes in England: 1995-2002.

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.

Changes in patient characteristics and outcomes for radical cystectomy in England.

OBJECTIVES: To describe temporal changes in patient characteristics and outcomes for radical cystectomy (RC) in England between 1995 and 2002, using routinely collected administrative data. PATIENTS AND METHODS: Data were extracted from the Hospital Episode Statistics database of the Department of Health in England, describing all patients recorded as having undergone RC between 1995/1996 and 2001/2002; 8228 patients were included. RESULTS: Of the patients who had undergone RC, two-thirds were > or = 65 years old and 75.6% were men. From 1995/1996 to 2001/2002 the annual number of RCs increased from 1013 to 1254, the proportion of patients admitted as an emergency decreased from 6.5% to 4.9%, the mean length of hospital stay decreased from 20.7 days to 18.7 days, and in-hospital mortality rates fell from 5.3% to 3.6%. The length of hospital stay and in-hospital mortality rates were higher in older patients, in female patients, and in those admitted as an emergency. CONCLUSIONS: There was no sign of centralization of RCs over the study period, as the 25% increase in annual hospital volume was accompanied by a similar increase in the annual number of RCs. Length of hospital stay and in-hospital mortality rates have decreased.

Threshold volumes for urological cancer surgery: a survey of UK urologists.

OBJECTIVE: To determine minimum threshold levels of activity set by surgeons for urological cancer surgery, and to relate threshold levels to stated current procedural volume. METHODS: In all, 307 consultant urological surgeons were sent a questionnaire asking them to state for four urological cancer operations of different complexity their current procedural volume; whether minimum volume thresholds per surgeon should be implemented; and if so, the level of such thresholds; 212 (69%) replied. RESULTS: For all four procedures >/= 75% of surgeons advocated the setting of a minimum volume threshold. Overall, surgeons set the highest thresholds for radical prostatectomy and the lowest for radical cystectomy with continent diversion. There was no significant association between either the principle of supporting minimum volume thresholds or the level of such a threshold and the number of years worked as a consultant surgeon. The level of surgeon-derived minimum thresholds increased with increasing surgeon procedural volume. CONCLUSION: Most surgeons supported the principle of setting minimum volume thresholds. These thresholds appear to be influenced by current procedural volume and by procedural complexity. By setting thresholds greater than their current volume, some surgeons implicitly indicate that their current volume is insufficient to maintain their surgical competency.

A systematic review and critique of the literature relating hospital or surgeon volume to health outcomes for 3 urological cancer procedures.

PURPOSE: We performed a systematic review and critique of the literature of the relationship between hospital or surgeon volume and health outcomes in patients undergoing radical surgery for cancer of the bladder, kidney or prostate. MATERIALS AND METHODS: Four electronic databases were searched to identify studies that describe the relationship between hospital or surgeon volume and health outcomes. RESULTS: All included studies were performed in North America. A total of 12 studies were found that related hospital volume to outcomes. For radical prostatectomy and cystectomy all 8 included studies showed improvement in at least 1 outcome measure with increasing volume and never deterioration. For nephrectomy the 4 included studies produced conflicting results. Four studies were found that related surgeon volume to outcomes. All radical prostatectomy and cystectomy studies showed that some outcomes were better with higher surgeon volume and never deterioration. We did not find any studies of the effect of surgeon volume on outcomes after nephrectomy. The 3 studies of the combined effect of hospital and surgeon volume on outcomes after radical prostatectomy or cystectomy suggest that high volume hospitals have better outcomes, in part because of the effect of surgeon volume and vice versa. CONCLUSIONS: Outcomes after radical prostatectomy and cystectomy are on average likely to be better if these procedures are performed by and at high volume providers. For radical nephrectomy the evidence is unclear. The impact of volume based policies (increasing volume to improve outcomes) depends on the extent to which "practice makes perfect" explains the observed results. Further studies should explicitly address selective referral and confounding as alternative explanations. Longitudinal studies should be performed to evaluate the impact of volume based policies.
