The effect of prostatectomy on symptom severity and quality of life.

OBJECTIVE: To determine the effectiveness of prostatectomy in reducing symptom severity and bother and in improving disease-specific and general quality of life. PATIENTS AND METHODS: A prospective, cohort study was performed in National Health Service and private hospitals in the Northern, Wessex, Mersey, and South-West Thames Health Regions which comprised 5276 men undergoing prostatectomy recruited by 101 of the 106 (96%) surgeons (specialist and non-specialist) performing prostatectomy during a 6-month period. Patients were assessed using the American Urological Association (AUA) Symptom Index Score, the AUA symptom bother score, disease-specific and generic quality-of-life scores, the occurrence of adverse events (urinary incontinence, erectile impotence and retrograde ejaculation) and three global (general) questions on the results of their treatment. The outcome was assessed 3 months after surgery. RESULTS: Prostatectomy was effective in reducing both symptoms (initial mean score 20.1 reduced to 7.4, P < 0.001) and symptom bother (initial mean score 14.4 reduced to 4.3, P < 0.001). Not all men experienced a good reduction in symptoms; 121 (3.9%) were worse, 301 (9.6%) were the same, and 721 (23%) experienced only slight improvement. The type of operation, grade of principal operator and use of pre-operative investigations were not associated with the extent of symptomatic improvement. Changes in symptom severity were highly correlated with changes in bothersomeness++ and disease-specific quality of life but not with generic quality of life. A third of men who were continent before surgery reported some incontinence 3 months later, although only 6% found it a problem. Two-thirds of men experienced retrograde ejaculation and 31% experienced some erectile impotence following surgery. CONCLUSIONS: Prostatectomy is effective in reducing symptoms in most men. Men who experience a substantial reduction in symptoms were more likely to report a favourable outcome. The study confirmed that approximately one-third of men reported an unfavourable result 3 months after their operation.

The National Prostatectomy Audit: the clinical management of patients during hospital admission.

OBJECTIVE: To determine everyday practice in the hospital management of men undergoing prostatectomy and the extent of its variation. PATIENTS AND METHODS: A total of 5361 patients, who represented 89% of all those undergoing prostatic procedures in four health regions (Mersey, Wessex, Northern and South West Thames) and one test site (within Trent) were recruited by 103 (97%) surgeons. Clinical information was collected on a pre-coded data collection form which was completed during the hospital stay by the principal operator. Patient identification occurred at the time of surgery. RESULTS: Important findings included: (i) both older men and those of higher social class were more likely to undergo prostatectomy with fewer symptoms; (ii) men who waited longer for surgery had worse symptoms by the time of their operation; (iii) there were unexplained differences in routine pre- and post-operative investigation and treatment. Half the men had their flow rate or residual urine measured as part of their pre-operative assessment. About half the men received prophylactic antibiotics; (iv) when large groups were analysed, a consistent proportion of men throughout the study (12%) were undergoing the operation for a second time. The clinical course of men having a repeat operation differed in many ways from those having a first time procedure; (v) the larger proportion of men (62%) had surgery for strong indications as opposed to symptoms alone; (vi) although most operations were performed by consultants, emergency admissions, though symptomatically more severe and sicker, were more likely to be operated on by trainee surgeons; (vii) significant variation in mean pre-operative symptom severity and bother scores were seen between surgeons. CONCLUSION: The clinical management of prostatectomy has been defined in a large and representative UK sample. In some circumstances consistent variations have been identified. It is not yet clear whether these variations influence outcome. These data can be used by surgeons wishing to compare their own patient management with that described here.

The feasibility and cost of a large multicentre audit of process and outcome of prostatectomy.

Objective--To determine the feasibility of performing multicentre process and outcome audits of common interventions taking prostatic procedures as an example. Design--Prospective, cohort study. Setting--All National Health Service and independent hospitals in Northern, Wessex, Mersey, and South West Thames health regions. Patients--5361 men undergoing prostatectomy identified by 103 of the 107 urologists and general surgeons performing prostatectomy in the study regions. Main measures-- Rates of participation by surgeons and patients; completeness of clinical data provided by surgeons; patient response rate and completeness of patient derived data; and cost. Results--Most surgeons (103,96%) agreed to participate. Overall, the proportion of eligible patients invited to take part was high (89%), although this was only measured in South West Thames, where dedicated data collectors were employed. Few men (80, 1.5%) declined to participate. Of those surviving for three months after surgery, 82.4% (4226) completed and returned the postal questionnaire. The response rate was higher in South West Thames (86.7%) than in the other regions (80.6%-80.8%). The audit was well received: 91% of patients found the questionnaire easy to complete and only 2.3% of them disapproved. Completeness of data was high with both the hospital and patient questionnaires. Missing data occurred in less than 5% of responses to most questions. The attributable cost was 34.50 pounds per patient identified or 44 pounds for patients in whom either the treatment outcome or vital status was known three months after their prostatectomy. Conclusions--This multicentre audit of process and outcome of prostatectomy proved feasible in terms of surgeon participation, patient identification, and the quantity and quality of data collection. Whether the cost was warranted will depend on how surgeons use the audit data to modify their practice.
