Supplementary Material for: The Acute Cystitis Symptom Score for Patient-Reported Outcome Assessment

<i>Objectives:</i> 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. <i>Materials and Methods:</i>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. <i>Results:</i> 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. <i>Conclusion:</i> 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
