In one middle-income country, elderly ED patients were delirious >10% of the time. Delirium was underdiagnosed and was associated with an increased 30-day mortality rate. Delirium screening needs to be improved, potentially focusing on high-risk patients.

Purpose This study aimed to determine the validity of ultrasonographic measurement of the rectus femoris muscle (RFM) thickness as a screening tool for low appendicular muscle mass (ASM) to diagnose sarcopenia and to determine the cut-off point of RFM thickness in the Thai population. Patients and methods We enrolled 857 community-dwelling adults aged 60 years and older who were diagnosed with sarcopenia using the Asian Working Group for Sarcopenia-2019 algorithm. The RFM thickness was measured using ultrasonography and compared with bioelectrical impedance analysis (BIA) data. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were evaluated, and the area under the receiver operating curve (AUROC) was used to determine the accuracy of the test. Results A total of 857 participants were included in the study. Overall, when the cut-off values of RFM thickness of ≤1.1 cm were used for male and ≤1 cm for female, the highest sensitivity for sarcopenia diagnosis was 90.9% and specificity was 92.2%. The PPV was 76.6, and the NPV was the highest at 97.3. The highest sensitivity for the diagnosis of severe sarcopenia was 92.5% and specificity was 97.4%. The AUROC of the cut-off point of RFM thickness for the diagnosis of sarcopenia was 0.92 (95% confidence interval [CI], 0.89−0.94); for severe sarcopenia, it was 0.95 (95% CI, 0.92−0.98). Conclusion Measuring RFM thickness using ultrasonography is a feasible and reliable screening test for sarcopenia, and the cut-off values of ≤1.1 cm for male and ≤1 cm for female showed the highest accuracy for confirming low ASM in the Thai population.

BackgroundIn disaster situations, the elderly are considered to be a particularly vulnerable population. Preparedness is the key to reduce post-disaster damage. There is limited research in middle-income countries on how well elderly emergency department (ED) patients are prepared for disaster situations. The objective of this study was to determine the attitudes and behavior of elderly ED patients toward disaster preparedness.MethodsThis study was a cross-sectional face-to-face survey at one urban teaching hospital in Bangkok, Thailand between August 1st and September 30th, 2016. Patients aged 60 and older who presented to the ED were included to this study. We excluded patients who had severe dementia [defined as Short Portable Mental State Questionnaires (SPMSQ) > 8], were unable to speak Thai, had severe trauma and/or needed immediate resuscitation. The survey instruction was adapted from previous disaster surveys. This study was approved by the Vajira Institutional Review Board (IRB).ResultsA total of 243 patients were enrolled. Most of them were female [154 patients (63.4%)]. The median age was 72 [Interquartile range (IQR) 66–81] years and the most common underlying diseases were hypertension [148 patients (60.9%)] and diabetes [108 patients (44.4%)]. The majority of patients [172 patients (72.4%)] reported that they had had some teaching about disaster knowledge from a healthcare provider and had experienced a disaster [138 patients (56.8%)]. While 175/197 (81.8%) patients who had underlying diseases reported that they had a medication supply for disaster situations, only 61 (25.1%) patients had an emergency toolbox for disasters. Most patients (159, 65.4%) did not know the emergency telephone number, and 133 (54.7%) patients reported transportation limitations.ConclusionsWhile most Thai elderly ED patients reported having a medication supply for disaster situations, many lacked comprehensive plans for a disaster situation. Work needs to be done to improve the quality of preparedness in disaster situations among elderly patients. Future research should focus on preparedness knowledge regarding evacuation, and shelter/residence for older patients.

Background This study aimed to determine the prevalence of infectious diseases and risk factors for one-year mortality in elderly emergency department (ED) patients. Methods A retrospective cohort study of patients aged 65 and over who visited the ED of one urban teaching hospital in Bangkok, Thailand and who were diagnosed with infectious diseases between 1 January 2016 and 30 June 2016. Results There were 463 elderly patients who visited ED with infectious diseases, accounting for 14.5% (463/3,196) of all elderly patients’ visits. The most common diseases diagnosed by emergency physicians (EPs) were pneumonia [151 (32.6%) patients] followed by pyelonephritis [107 (23.1%) patients] and intestinal infection [53 (11.4%) patients]. Moreover, 286 (61.8%) patients were admitted during the study period. The in-hospital mortality rate was 22.7%. 181 (39.1%) patients died within 1 year. Our multivariate analysis showed that age 85 years and older [odds ratio (OR) = 1.89; 95% confidence interval (CI): 1.36–2.63], Charlson Co-morbidity Index score ≥ 5 (OR = 3.51; 95% CI2.14–5.77), lactate ≥4 mmol/l (OR = 2.66;95% CI 1.32–5.38), quick Sequential Organ Failure Assessment (qSOFA) score ≥ 2 (OR = 5.46; 95% CI 2.94–10.12), and platelet count < 100,000 cells/mm 3 (OR = 3.19; 95% CI 1.15–8.83) were associated with 1-year mortality. Conclusions In one middle-income country, infectious diseases account for 14.5% of elderly ED patients. Almost two-thirds of patients presenting to ED with infection are admitted to hospital. One-third of elderly ED patients with infection died within 1 year. Age ≥ 85 years, Charlson Co-morbidity Index score ≥ 5, lactate ≥4 mmol/l, qSOFA score ≥ 2, and platelet count < 100,000 cells/mm 3 predicted 1-year mortality rate.
