Comparison of Self-administered IPSS, Sanitary Staff-supervised IPSS, Medical History and Clinical Parameters
Comparison of Self-administered IPSS, Sanitary Staff-supervised IPSS, Medical History and Clinical Parameters
Descriptive prospective study carried out to compare the results obtained by
 self-administered IPSS (International Prostate Symptom Score), Sanitary staff-supervised IPSS
 and directed medical interview and its correlation with clinical parameters in the assessment
 of lower urinary tract symptoms in males.
The IPSS is a validated questionnaire (also in spanish language) widely used to evaluate
 lower urinary tract symptoms (LUTS) in males. It contains 7 multiple-choice questions related
 to urinary symptoms with a Likert response scale and 1 question assessing quality of life.
 This test has been approved for self-administration and its purpose is quantifying and
 monitoring symptoms severity.

 The aim of this study is to compare the scores achieved in a self-administered IPSS
 questionnaire with those obtained when the questionnaire is answered with the help and
 supervision of a sanitary staff. These results will also be contrasted with the scores
 retrieved in a standard directed medical interview and correlated with objective functional
 parameters of lower urinary tract symptoms.

 A descriptive prospective study will be carried out analysing lower urinary tract symptoms
 from patients over 50 years old.

 All patients will be provided with a IPSS to be fulfilled at home and after a short period of
 time without any change in his LUTS treatment, the patient will repeat the questionnaire in
 the hospital under the supervision of a sanitary staff.

 A standard structured medical interview focusing in LUTS will be performed to every patient.
 In order to compare the results achieved with both IPSS with those obtained during the
 interview a Likert score was assigned to each question.

 At the same time, objective lower urinary tract symptoms data will be collected and compared
 to the results obtained previously with both the questionnaires and the medical interview.
 Uroflowmetry and post physiological void residual volume measurement with ultrasonography
 will be performed as evaluation of voiding symptoms. On the other hand, filling symptoms will
 be evaluated with a validated 3-day voiding diary to be accomplished previously to the
 medical visit.

 Data to be collected includes Uroflowmetry parameters Qmax, Qm, curve shape type and time to
 Qmax, ultrasonographic PVR (post-void residual) measurement and daytime and nightime number
 of voids, medium volume of void, number of urgency and urge incontinence episodes and maximal
 vesical functional volume wich will be extracted from the 3-day voiding diary.

 A statistical analysis will be performed to compare the scores obtained through the
 questionnaires and the medical interview and the correlation of each of them with the
 objective clinical parameters obtained.
