Objective: Development and validation of a simple and standardized self-reporting questionnaire for acute uncomplicated cystitis (AUC) assessing typical and differential symptoms, quality of life and possible changes after therapy in female patients with AUC. Materials and Methods: Literature research, development and evaluation of the Acute Cystitis Symptom Score (ACSS), an 18-item self-reporting questionnaire including (a) six questions about ‘typical' symptoms of AUC, (b) four questions regarding differential diagnoses, (c) three questions on quality of life and (d) five questions on additional conditions which may affect therapy. The ACSS was evaluated in 286 women (mean age 32.3 ± 12.3 years) in the Russian and Uzbek language. Measurements of reliability, validity, predictive ability and responsiveness were performed. Results: Cronbach's alpha for the ACSS was 0.89, split-half reliability was 0.92 and correlation between halves was 0.85. Mann-Whitney test revealed significant difference scores of the ‘typical' domain between patients and controls (10.75 vs. 2.02, p < 0.001). The optimal threshold score was 6 points, with a 94% sensitivity and 90% specificity to predict AUC. The symptom score decreased significantly when comparing before and after therapy (10.7 vs. 2.1, p < 0.001). Conclusion: The new validated ACSS is accurate enough and can be recommended for clinical studies and practice for initial diagnosis and monitoring treatment of AUC. Evaluation in other languages is in progress. © 2014 S. Karger AG, Basel

Objectives: The Acute Cystitis Symptom Score (ACSS) was developed as a self-reporting questionnaire for clinical diagnosis of acute uncomplicated cystitis (AUC) and symptomatic changes in female patients. The aim of the present study was to assess the utility of the different domains of ACSS including the ‘dynamics' domain after therapy. The applicability of these domains in assessing changes in symptoms, as a function of time, in this population was investigated. Materials and Methods: During the validation process of the ACSS in Uzbek and Russian languages, a subgroup of patients (n = 63) returned after therapy and filled in part B of ACSS. Descriptive statistics were used, where suitable. Results: The reduction of typical symptoms and quality of life (QoL) assessment between first and follow-up visit correlated significantly with answers in the ‘dynamics' domain. Success/cure and non-success/failure could be clearly differentiated by the scores obtained in ‘typical' and ‘QoL' domains. Conclusion: The ACSS has proven to be a useful instrument to clinically diagnose AUC in women. It is also a suitable instrument for patient-reported outcome assessment, with applicability in both daily practice and in clinical studies. Slight modifications in the ‘dynamics' domain will even increase the applicability.

Background and Objectives: Acute uncomplicated cystitis (AC) is common among women. Acute onset of specific typical symptoms may serve as reliable criteria for developing a cost-effective strategy to make an accurate diagnosis of AC. We aimed to evaluate the diagnostic values of most common symptoms and signs of AC depending on their presence and severity. Methods: The current trial was designed as a case-control study. Data derived from the Acute Cystitis Symptom Score (ACSS) database were analyzed. Diagnostic values of the symptoms and their severity were assessed via the calculations of the sensitivity and specificity, odds ratio, positive and negative likelihood ratios. The strength of associations was estimated by the coefficient of correlation (Pearson’s R). Results: Data from 819 female subjects (423 Patients, 396 controls) with the mean age of 37.1 ± 15.3 were analyzed. Highest diagnostic values for AC in this study belonged to dysuria, urgency, and frequency. Interestingly, complaints of vaginal discharge was not found to decrease the odds for having AC in the study population. Conclusions: The severity of the symptom is even more essential than just its presence for an accurate diagnosis. The ACSS is an accurate tool and may be recommended for clinical practice and studies for diagnosis of AC in women. Further studies and unification of terms are need.

This study aimed to reevaluate the Acute Cystitis Symptom Score (ACSS). The ACSS is a simple and standardized self-reporting questionnaire for the diagnosis of acute uncomplicated cystitis (AC) assessing typical and differential symptoms, quality of life, and possible changes after therapy in female patients with AC. This paper includes literature research, development and evaluation of the ACSS, an 18-item self-reporting questionnaire including (a) six questions about “typical” symptoms of AC, (b) four questions regarding differential diagnoses, (c) three questions on quality of life, and (d) five questions on additional conditions that may affect therapy. The ACSS was evaluated in 228 women (mean age 31.49 ± 11.71 years) in the Russian and Uzbek languages. Measurements of reliability, validity, predictive ability, and responsiveness were performed. Cronbach’s alpha for ACSS was 0.89, split-half reliability was 0.76 and 0.79 for first and second halves, and the correlation between them was 0.87. Mann-Whitney U test revealed a significant difference in scores of the “typical” symptoms between patients and controls (10.50 vs. 2.07, p < 0.001). The optimal threshold score was 6 points, with a 94% sensitivity and 90% specificity to predict AC. The “typical” symptom score decreased significantly when comparing before and after therapy (10.4 and 2.5, p < 0.001). The reevaluated Russian and Uzbek ACSS are accurate enough and can be recommended for clinical studies and practice for initial diagnosis and monitoring the process of the treatment of AC in women. Evaluation in German, UK English, and Hungarian languages was also performed and in other languages evaluation of the ACSS is in progress
