Retrospective evaluation of the rockall risk scoring system in patients with nonvariceal upper gastrointestinal hemorrhage at a community hospital
… (UGIH), the majority of hospitals do not risk-stratify patients with UGIH. One of the major challenges in triaging patients with nonvariceal UGIH is identifying patients’ who are at low risk. We retrospectively identified Rockall scores of 160 patients and the proportion of low-risk …

The relationship between faecal haemoglobin concentration and risk of significant colorectal neoplasia in screening and symptomatic populations.
… Hb concentration as a strong predictor of future risk of advanced neoplasia. The use of FIT in symptomatic patients was also evaluated, with results showing that using a cut-off faecal Hb concentration of any detectable Hb would have ruled out colorectal cancer and could have reduced the referral …

Good risk assessment practice in hospitals
Risk assessment is essential to ensure safety in hospitals. However, hospitals have paid little attention to risk assessment. Several problems have already been identified in the literature about current risk assessment practice, such as inadequate risk assessment guidance and bias in risk scoring. …
