Aims and objectives: To determine the risk factors of blood culture contamination done in ED and those done in the MHDU/MICU among patients admitted with medical illness. Material and Methods: This is a two months’ prospective observational study comparing blood culture contamination rate and risk factors associated with contamination between ED and MICU/MHDU. A total of 998 patients were included in the study who underwent blood culture in ED and MICU/MHDU. 570 in ED and 428 in MICU/MHDU were included after meeting exclusion and inclusion criteria. Results: Blood culture growths were higher in ED (19%). Most common growth was CoNS (4%). The overall contamination rate in this study was (4.8%) The contamination rate was lower in ED (4.4%) when compared to MICU/MHDU (5.4%).

Background Almost one-third of patients with migraine do not adequately respond to triptans. We examined factors contributing to frovatriptan response in patients with migraine. Methods We enrolled new patients with migraine who consecutively visited our headache clinic. Eligible patients were instructed to take 2.5 mg of frovatriptan as soon as possible after migraine attack. The responsiveness was determined by whether headache was relieved or absent within 4 hours after the intake of frovatriptan. We assessed frovatriptan to be efficacious when headache responded to its administration in at least one of two successive migraine attacks and inefficacious when headache was not relieved in either attack. We included demographic, clinical and psychiatric variables in the analysis of factors associated with frovatriptan response. Results Of 128 eligible patients, 28 (21.9%) experienced frovatriptan inefficacy. In 24 patients with current major depressive disorder, 12 (50.0%) had frovatriptan inefficacy. Only current major depressive disorder was identified as a risk factor for inefficacy (odds ratio = 5.500, 95% confidence interval 2.103–14.382, p = 0.001). Conclusions Depression may be a risk factor of frovatriptan inefficacy in patients with migraine, even though half of patients with major depressive disorder respond to frovatriptan.

Background: The aim of this study was to determine the frequency of COPD exacerbations in our Emergency Department, as well as the hospitalization-related factors. Methods: Prospective observational study conducted in the Emergency Department of Salnés County Hospital among patients admitted for COPD exacerbation. Admission predictors were determined by multivariate analysis. Results: There were 409 exacerbations in 239 patients (79% male, mean age 75). 57% of exacerbations required hospitalization. Hospitalization-related factors were impaired oxygenation (p<0.001), presence of neutrophilia (p<0.01) and prescription of antibiotics in the Emergency Department (p<0.05). Conclusions: COPD exacerbation accounts for over 1% of all visits to our Emergency Department. 57% of them required hospitalization. Impaired oxygenation, greater neutrophilia and prescription of antibiotics in the Emergency Department were associated with greater probability of admission.

Abstract Background: Blood cultures are indispensable for detecting life-threatening bacteremia. Little is known about associations between contamination rates and topical disinfectants for blood collection in adults.Objective: We sought to determine whether a change in topical disinfectants was associated with the rates of contaminated blood cultures in the emergency department of a single institution.Methods: This single-center, retrospective observational study of consecutive patients aged 20 years or older was conducted in the emergency department (ED) of a university hospital in Japan between August 1, 2018 and September 30, 2020. Pairs of blood samples were collected for aerobic and anaerobic culture from the patients in the ED. Physicians selected topical disinfectants according to their personal preference before September 1, 2019; alcohol/chlorhexidine gluconate (ACHX) was mandatory thereafter, unless the patient was allergic to alcohol. Regression discontinuity analysis was used to detect the effect of the mandatory usage of ACHX on rates of contaminated blood cultures.Results: We collected 2,141 blood culture samples from 1097 patients and found 164 (7.7%) potentially contaminated blood cultures. Among these, 445 (20.8%) were true bacteremia and 1,532 (71.6%) were true negatives. Puncture site disinfection was performed with ACHX for 1,345 (62.8%) cases and with povidone-iodine (PVI) for 767 (35.8%) cases. The regression discontinuity analysis showed that mandatory ACHX usage significantly reduced the blood culture contamination rate by 9.6% (95% confidence interval (CI): 5.0%–14.2%, P <0.001).Conclusion: Rates of contaminated blood cultures were significantly lower when ACHX was used as the topical disinfectant.

IntroductionLimited data exist on the epidemiology of acute hypoxaemic respiratory failure (AHRF) in low-income countries (LICs). We sought to determine the prevalence of AHRF in critically ill adult patients admitted to a Ugandan tertiary referral hospital; determine clinical and treatment characteristics as well as assess factors associated with mortality.Materials and methodsWe conducted a prospective observational study at the Mulago National Referral and Teaching Hospital in Uganda. Critically ill adults who were hospitalised at the emergency department and met the criteria for AHRF (acute shortness of breath for less than a week) were enrolled and followed up for 90 days. Multivariable analyses were conducted to determine the risk factors for death.ResultsA total of 7300 patients was screened. Of these, 327 (4.5%) presented with AHRF. The majority (60 %) was male and the median age was 38 years (IQR 27–52). The mean plethysmographic oxygen saturation (SpO2) was 77.6% (SD 12.7); mean SpO2/FiO2 ratio 194 (SD 32) and the mean Lung Injury Prediction Score (LIPS) 6.7 (SD 0.8). Pneumonia (80%) was the most common diagnosis. Only 6% of the patients received mechanical ventilatory support. In-hospital mortality was 77% with an average length of hospital stay of 9.2 days (SD 7). At 90 days after enrolment, the mortality increased to 85%. Factors associated with mortality were severity of hypoxaemia (risk ratio (RR) 1.29 (95% CI 1.15 to 1.54), p=0.01); a high LIPS (RR 1.79 (95% CI 1.79 1.14 to 2.83), p=0.01); thrombocytopenia (RR 1.23 (95% CI 1.11 to 1.38), p=0.01); anaemia (RR 1.15 (95% CI 1.01 to 1.31), p=0.03) ; HIV co-infection (RR 0.84 (95% CI 0.72 to 0.97), p=0.019) and male gender (RR 1.15 (95% CI 1.01 to 1.31) p=0.04).ConclusionsThe prevalence of AHRF among emergency department patients in a tertiary hospital in an LIC was low but was associated with very high mortality. Pneumonia was the most common cause of AHRF. Mortality was associated with higher severity of hypoxaemia, high LIPS, anaemia, HIV co-infection, thrombocytopenia and being male.
