Rising prevalence of colonic diverticulosis in a westernized multi-ethnic Asian community.

BACKGROUND AND AIM: Singapore is a multi-ethnic country that has undergone rapid development over the last few decades, with increasing influence of western culture, and faces an aging population. Previously, a varying prevalence of colonic diverticulosis (CD) was reported by a few small studies. This study aims to evaluate the prevalence of CD in Singapore and identify associations with common gastrointestinal symptoms and risk factors. METHODS: We reviewed retrospective data of 20 395 consecutive colonoscopies performed from 2006 to 2016 for presence of CD and indications of screening, diarrhea, constipation, and abdominal pain. RESULTS: The prevalence of CD progressively increased from 2006 to 2016 (14.9% vs 23.9%, adjusted trend < 0.001), with an overall prevalence of 19.6%. Patients with CD were older and had higher body mass index (BMI). CD was significantly more prevalent in Chinese compared with Malay and Indian races (20.5% vs 18.9% vs 15.5%, P < 0.05), and in male patients compared with female patients (21.5% vs 17.6%, P < 0.05). Right-sided CD was more common than left-sided or pan diverticulosis (16.2% vs 8.3% vs 4.8%, P < 0.05). Age [odds ratio (OR), 1.060; 95% confidence interval (CI), 1.052-1.068], BMI (OR, 1.051; 95% CI, 1.028-1.075), male gender (OR, 1.317; 95% CI, 1.084-1.600), and abdominal pain (OR, 1.409; 95% CI, 1.168-1.699) were positively associated, while constipation (OR, 0.566; 95% CI, 0.452-0.709) was negatively associated with CD. CONCLUSION: The prevalence of CD in Singapore has progressively increased over the last decade and is associated with older age, higher BMI, and abdominal pain. These findings may provide insights for healthcare resource planning in the region.

One size fits all? Challenges faced by physicians during shift handovers in a hospital with high sender/recipient ratio.

INTRODUCTION: The aim of the present study was to investigate the challenges faced by physicians during shift handovers in a university hospital that has a high handover sender/recipient ratio. METHODS: A multifaceted approach was adopted, comprising recording and analysis of handover information, rating of handover quality, and shadowing of handover recipients. Data was collected at the general medical ward of a university hospital in Singapore for a period of three months. Handover information transfer (i.e. senders' and recipients' verbal communication, and recipients' handwritten notes) and handover environmental factors were analysed. The relationship between 'to-do' tasks, and information transfer, handover quality and handover duration, were examined using analysis of variance. RESULTS: Verbal handovers for 152 patients were observed; handwritten notes on 102 (67.1%) patients and handover quality ratings for the handovers of 98 (64.5%) patients were collected. Although there was good task prioritisation (information transfer: p < 0.005, handover duration: p < 0.01), incomplete information transfer and poor implementation of nonmodifiable identifiers were observed. The high sender/recipient ratio of the hospital made face-to-face and/or bedside handover difficult to implement. Although the current handover method (i.e. use of telephone communication), allowed interactive communication, it resulted in systemic information loss due to the lack of written information. The handover environment was chaotic in the high sender/recipient ratio setting, and the physicians had no designated handover time or location. CONCLUSION: Handovers in high sender/recipient ratio settings are challenging. Efforts should be made to improve the handover processes in such situations, so that patient care is not compromised.
