RESUMO
INTRODUCTION@#This study aimed to assess the effectiveness of the emergency department observation unit (EDOU) for patients with acute pyelonephritis in a Singapore tertiary academic medical centre.@*METHODS@#We reviewed the clinical records of consecutive patients who presented with pyelonephritis between 1 July 2012 and 31 October 2014 to collect information on demographics, symptoms, signs, laboratory and radiological results, treatment, and clinical outcomes.@*RESULTS@#Of 459 emergency department (ED) patients who were identified as having pyelonephritis, 164 (35.7%) were managed in the EDOU. Successful management in the EDOU was achieved in 100 (61.0%) patients. Escherichia coli was the predominant (64.6%) micro-organism in urine cultures and was positive in 106 patients. Patients diagnosed with acute pyelonephritis who were successfully managed in the EDOU had a lower incidence of nausea (32.0% vs. 60.9%, p < 0.001) and vomiting (15.0% vs. 50.0%, p < 0.001) compared to those who were not successful.@*CONCLUSION@#EDOU is useful for both observation and treatment of patients with acute pyelonephritis. Urine cultures are sufficient for the identification of the culprit micro-organism. Patients who present with prominent symptoms of vomiting should have routine administration of antiemetics, while consideration for second-line antiemetics is recommended for those with persistent symptoms.
RESUMO
<p><b>INTRODUCTION</b>Prolonged stay in acute hospitals increases the risk of hospital-acquired infections in older patients, and disrupts patient flow and access to care due to bed shortages. We aimed to investigate the factors associated with prolonged length of stay (pLOS) among older patients (aged ≥ 78 years) in a tertiary hospital, to identify the potentially modifiable risk factors that could direct interventions to reduce length of stay (LOS).</p><p><b>METHODS</b>During a three-month period from January 2013 to March 2013, we identified 72 patients with pLOS (LOS ≥ 21 days) and compared their demographic and clinical variables with that of 281 randomly selected control patients (LOS < 21 days) using univariate and multivariate logistic regression analyses.</p><p><b>RESULTS</b>The mean age of the patients was 85.30 ± 5.34 years; 54% of them were female and 72% were of Chinese ethnicity. Logistic regression revealed the following significant factors for increased LOS: discharge to intermediate and long-term care services (odds ratio [OR] 9.22, 95% confidence interval [CI] 3.56-23.89; p < 0.001); increased severity of illness (OR 2.41, 95% CI 1.12-5.21; p = 0.025); and presence of caregiver stress (OR 3.85, 95% CI 1.67-8.91; p = 0.002).</p><p><b>CONCLUSION</b>Presence of caregiver stress and nursing home placement are potential modifiable risk factors of pLOS among older patients. Early identification and management of caregiver stress, as well as expediting discharge planning, may help to reduce the length of stay for this cohort.</p>
