Cross-cultural translation into Chinese and psychometric evaluation of a screening tool for nocturia: the Targeting the individual's Aetiology of Nocturia to Guide Outcomes (TANGO) questionnaire.

INTRODUCTION: We conducted translation and psychometric validation of a self-administered, 22-item dichotomous response-based questionnaire to identify nocturia aetiologies and co-morbidities in adult patients. METHODS: The Targeting the individual's Aetiology of Nocturia to Guide Outcomes (TANGO) questionnaire was forward- and backward-translated, then finalised using a standardised methodology. The resulting version, a Chinese version of the TANGO [TANGO (CV)], was evaluated for internal consistency, test-retest reliability, content validity, convergent validity, criterion validity, and discriminant validity via responses from 65 participants (46 men and 19 women; mean age, 67 years, range, 50-88), in comparison with other validated questionnaires and a 4-day bladder/sleep diary. RESULTS: Only 0.4% of responses were missing; 3% of participants required assistance with comprehension. The Kuder-Richardson Formula 20 (KR-20) coefficient for the whole tool was 0.711. Kappa values for individual domains and the whole tool varied from 0.871 to 0.866, indicating satisfactory test-retest reliability. There was strong agreement between the sum of positive responses to each domain and the whole tool (intra-class correlation coefficient=0.878-1.000). Modest correlations (ρ=0.4-0.6) were detected between the tool and bladder/sleep diary-based parameters for convergent validity. Criterion validity was confirmed for each domain and the whole tool [ρ=0.287-0.687]. In receiver operating characteristic analysis, the tool could distinguish patients (≥2 nocturia episodes/night) from controls (≤1 nocturia episode/night) [Youden's J statistic=0.453, area under the curve=0.818, 95% confidence interval (CI)=0.683-0.953] and patients with significant nocturia distress from patients with mild nocturia distress (Youden's J statistic=0.398, area under the curve=0.729, 95% CI=0.581-0.878). CONCLUSION: The TANGO (CV) was formally crossculturally adapted and translated. Its psychometric properties (except sensitivity to change) were validated.

Effect of SARS and COVID-19 outbreaks on urology practice and training.

INTRODUCTION: The objective was to investigate the changes in urology practice during coronavirus disease 2019 (COVID-19) pandemic with a perspective from our experience with severe acute respiratory syndrome (SARS) in 2003. METHODS: Institutional data from all urology centres in the Hong Kong public sector during the COVID-19 pandemic (1 Feb 2020-31 Mar 2020) and a non-COVID-19 control period (1 Feb 2019-31 Mar 2019) were acquired. An online anonymous questionnaire was used to gauge the impact of COVID-19 on resident training. The clinical output of tertiary centres was compared with data from the SARS period. RESULTS: The numbers of operating sessions, clinic attendance, cystoscopy sessions, prostate biopsy, and shockwave lithotripsy sessions were reduced by 40.5%, 28.5%, 49.6%, 44.8%, and 38.5%, respectively, across all the centres reviewed. The mean numbers of operating sessions before and during the COVID-19 pandemic were 85.1±30.3 and 50.6±25.7, respectively (P=0.005). All centres gave priority to cancer-related surgeries. Benign prostatic hyperplasia-related surgery (39.1%) and ureteric stone surgery (25.5%) were the most commonly delayed surgeries. The degree of reduction in urology services was less than that during SARS (47.2%, 55.3%, and 70.5% for operating sessions, cystoscopy, and biopsy, respectively). The mean numbers of operations performed by residents before and during the COVID-19 pandemic were 75.4±48.0 and 34.9±17.2, respectively (P=0.002). CONCLUSION: A comprehensive review of urology practice during the COVID-19 pandemic revealed changes in every aspect of practice.

Attitudes, acceptance, and registration in relation to organ donation in Hong Kong: a cross-sectional study.

INTRODUCTION: The objective of this study was to investigate the discrepancy between individuals with positive attitudes towards organ donation and the actual number of registered organ donors in Hong Kong, and to investigate the best modalities for promoting more organ donor registrations. METHODS: This cross-sectional telephone survey was conducted in Hong Kong. Telephone numbers were selected randomly. Upon successful contact with a household, the eligible household member who had the most recent birthday was selected to participate in the telephone interview. RESULTS: A total of 1000 Hong Kong Chinese residents were interviewed successfully. The response rate was 53.8%. The majority of the respondents were female (68.3%) and were aged 51 to 60 years (24%) or ≥61 years (43.6%). Among the respondents, 31.3% were willing to donate their organs after death; 43.3% were indecisive, and 25.4% refused. Among those who were willing to donate organs after death, only 34.2% had registered with the Centralised Organ Donation Register (CODR). Among those who were willing to donate organs after death but had not yet registered on CODR, 52.2% said they were not determined enough to take action, 47.8% said they were too busy, 37.8% said they were too lazy, and 20.4% said they were always forgetful about registering. In all, 32.8% of the interviewees were not aware of the ways to register as a prospective organ donor. Among non-messenger social media platforms, Facebook, YouTube, and Instagram were the most commonly used. Most participants believed that Facebook and YouTube were effective for engaging audiences. CONCLUSIONS: More effort should be made to facilitate organ donor registration in face-to-face settings via promotional booths and in online settings via appropriate social media platforms.
