Without a “gold standard”, comparative research will be hampered and clinicians will hesitate to select one survey for routine use. Thus, we evaluated the three most described surveys that have been reported to predict symptom severity at baseline visit and to monitor treatment response: 1) the Farkat survey (for completion by 4–10 year old patients with parental help), 2) the Akbal survey (for completion by the parents of 4–10 year old patients), and 3) the Nelson survey (for completion by the 11–17 year old patient). We compared total symptom scores from the three surveys to clinical evaluation by the specialist and report our findings. METHODS The study protocol was approved by our Institutional Review Board. Subjects consisted of otherwise normal children between the ages of 4 and 17 years who were seen for the first time for daytime voiding dysfunction at a pediatric urology practice. Parents of children (4–10 years) completed the survey by Akbal, which had previously been validated in Turkey, while children (4–10 years) completed the survey by Farhat, which had been previously validated in Canada, with the help of a parent. Older children (11–17) years completed the survey by Nelson without help. The surveys were kept by the research nurse and the examining physician was blinded to the survey results. The physician scored the patient for severity of symptoms at the time of the initial visit and those scores were compared to the scores obtained by the surveys. RESULTS There were 71 subjects (36 male, 35 female). Of these, 36 were ages 4–10 years; 35 were ages 11–17 years. Using ordinal regression, we found that parental report of child symptoms using the Akbal survey reflected the physician symptom rating (very mild, mild, moderate, severe) fairly well (n=36; p=.028). Younger child (4–10 years) self-report using the Farkat survey was less useful (n=36; p=.374); older children (11–17 years) using the Nelson self-report survey strongly reflected physician symptom rating (n=35; p=.001). CONCLUSIONS The Nelson and Akbal surveys, in older and younger children respectively, were more accurate than the Farkat survey for measuring symptom severity. Using the most accurate scoring system allows physicians to accurately grade the severity of symptoms, to track treatment success, and allows for a scientific basis for comparative research. These data are helpful in determining a “gold standard” survey instrument for measuring pediatric voiding dysfunction. © 2011 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 185Issue 4SApril 2011Page: e328-e329 Advertisement Copyright & Permissions© 2011 by American Urological Association Education and Research, Inc.MetricsAuthor Information Joseph Barone New Brunswick, NJ More articles by this author Akira Yamamota New Brunswick, NJ More articles by this author Daniel Su New Brunswick, NJ More articles by this author Schneider Dona New Brunswick, NJ More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
