[International prostate symptom score: comparison of doctor and patient]. FT International prostate symptom score: medico e paziente a confronto.

The AUA 7 score was originally designed and validated to be self administrated to patients with LUTS, its subsequent endorsement by the WHO - BPH committee made it the most widely used. Translation into different was provided and sometime validated. Aim of the study was to investigate the possibility to self administer the IPSS questionnaire to patients referred to our Institution for lower urinary tract symptoms. Two hundred and thirty-tree consecutive patients were given the IPSS questionnaire as a part of the routine diagnostic schedule; a senior resident was available to answer any possible question from the patient. After the form was returned, a second IPSS questionnaire was filled in by investigator following patient interview. Data were entered into an Excel database and the following parameters were investigate: number of forms completely filled in by patient, number of question answered in incomplete forms, degree of concordance between patient and investigator. One hundred and fifteen patients were able to fill the AUA 7 form completely; the quality of life question was answered by ninety-six patients only. Comparison of individual scores provided by the patient or assigned by the investigator showed a trend for the physician to underscore the patient problem for question 1-4 and to overestimate it in questions 5 to 7. At the lower range of the IPS score (0-7) no significant different between physician and patient was found. In the intermediate range (8-19) the physician tended to overestimate the patient symptoms. The reverse situations was found in the high score range (20-35). Globally, there was a trend for the patient score to be higher than the one assigned by the investigator, Doctor IPSS and quality of life scores appeared to be significantly related. No relation was found between doctor IPSS and the degree of bladder outlet obstruction as measured by parameter of pressure-flow study and diagnostic nomograms. The IPSS form appeared to be a difficult questionnaire for our patients and less than half of them were able to fill it in properly. Overall, the investigators tended to underestimate the patient voiding disturbances. Careful linguistic review of the Italian version of the IPSS questionnaire is required to make self evaluation of patient symptom possible. Symptom grading by a trained investigator did not seem to introduce any significant bias which might be of importance for the sake of clinical trials.
