Introduction: Low back pain (LBP) interferes with daily activities, which is why monitoring of functional disability is important. Non-urgent hospital visits are reduced due to the COVID-19 pandemic. Functional disability questionnaires serve as an alternative fo r patients to self-monitor their condition.Methods: This case-based study aimed to compare the Quebec Back Pain Disability Scale (QBPDS) with the Oswestry Disability Index (ODI) on their responsiveness in assessing functional disability of patients with LBP. Four databases (PubMed, Scopus, Cochrane, and Embase) were searched for literature. Two eligible studies were included in this report. The studies were assessed using the Centre for Evidence-Based Medicine critical appraisal tool for diagnostic studies. Data collected on the responsiveness of ODI and QBPDS were measured using the area under the curve (AUC) of a receiver operating curve (ROC), sensitivity, and specificity.Result: Both studies reported higher AUC values for ODI than QBPDS. One study reported higher sensitivity in ODI and identical specificity values for both ODI and QBPDS. QBPDS has comparable responsiveness to ODI in assessing functional disability of pat ients with LBP.Conclusion: Therefore, patients with low back pain can self-monitor their condition with QPBDS, as it is comparable to ODI and suitable for self-monitor during the C OVID-19 pandemicKeywords: assessment, disability evaluation, low back pain, musculoskeletal pain, surveys andquestionnaires

In March of 2020, the WHO has declared the state pandemic of COVID-19 that started in the city of Wuhan, China. The widespread of cases resulted in 2,877,476 cases and 73,582 death reported in Indonesia. It is commonly known that the respiratory system was the main problem in COVID-19, but it is recently reported that gastrointestinal involevment has a higher likelihood to develop into severe cases. Moreover, it is found that diarrhea is the most highly prevalent of the gastrointestinal signs and symptoms in COVID-19 patients. The aim of this evidence-based case report is to understand the association between diarrhea and severe cases of COVID-19. A search on Pubmed, Scopus and Cochrane result in five articles to be appraised using Centre for Evidence-Based Medicine (CEBM) critical appraisal tool. The most recent systematic review by Ghimere S et al (2020), found COVID-19 patients with diarrhea has higher likelihood of developin ginto a severe case (OR = 1.63, 95% CI: 1.11 – 2.38). While the cohort studies showed several prognostic factors that may potentially effect the outcome of severe COVID-19 cases. It is concluded that severe COVID-19 cases were more likely to be found in patients presenting with diarrhea. Thus, Confirmed COVID-19 patients with diarrhea should be carefully evaluated to anticipate worsening of symptoms.
