ABSTRACT

OBJECTIVES: To investigate the effects of an occupational therapy fall reduction home visit program for older adults admitted to the emergency department (ED) for a fall and discharged directly home. DESIGN: Single-blind, multicenter, randomized, controlled trial. SETTINGS: EDs in three acute care hospitals in Hong Kong. PARTICIPANTS: Individuals aged 65 and older who had fallen (N = 311). INTERVENTIONS: After screening for eligibility, 204 consenting individuals were randomly assigned to an intervention group (IG) and received a single home visit from an occupational therapist (OT) within 2 weeks after discharge from the hospital or a control group (CG) and received a well-wishing visit from a research assistant not trained in fall prevention. MEASUREMENTS: Both groups were followed for 12 months through telephone calls made every 2 weeks by blinded assessors with a focus on the frequency of falls. Another blinded assessor followed up on their status with telephone calls 4, 8, and 12 months after ED discharge. Prospective fall records on hospital admissions were retrieved from electronic databases; 198 individuals were followed for 1 year on an intention-to-treat basis. RESULTS: The percentage of fallers over 1 year was 13.7% in the IG (n = 95) and 20.4% in the CG (n = 103). There were significant differences in the number of fallers (P = .03) and the number of falls (P = .02) between the two groups over 6 months. Significant differences were found in survival analysis for first fall at 6 months (log-rank test 5.052, P = .02) but not 9 or 12 months. CONCLUSION: One OT visit after a fall was more effective than a well-wishing visit at reducing future falls at 6 months. A booster OT visit at 6 months is suggested.

ABSTRACT

INTRODUCTION: Acute pulmonary embolism (PE) is an uncommon but potentially fatal disease. Acute right ventricular failure, which can be demonstrated by echocardiography, is known to be an adverse prognostic factor in patients with acute PE. However, this diagnostic test is not always available in emergency departments and it is also an operator-dependent investigation. This study aimed to investigate whether cardiac troponin I (cTnI) levels could predict clinical outcomes in Chinese patients with PE. METHODS: This was a retrospective cohort study performed in a tertiary regional hospital in Hong Kong. For this study, 100 patients who were diagnosed with acute PE between January 1, 2002 and December 31, 2009 were recruited. Information, including demographic data, presenting symptoms and vital signs at presentation, predisposing factors for PE, results of diagnostic procedures and clinical outcomes, was collected from the medical records of these patients. RESULTS: 71% of recruited patients had elevated cTnI levels. High cTnI levels were associated with haemodynamic instability (odds ratio [OR] 5.30, 95% confidence interval [CI] 1.32-27.71; p = 0.019) and complicated clinical course (OR 6.34, 95% CI 1.76-22.9; p = 0.002). CONCLUSION: Elevated cTnI level was associated with a complicated clinical course in patients with acute PE. We suggest that measurements of cTnI levels be used for the early risk stratification of patients with PE in the emergency departments of hospitals.

ABSTRACT

This prospective study assessed the epidemiology of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) among patients with purulent skin and soft tissue infections (SSTIs) in Hong Kong. Among 298 patients with SSTIs, 10.4% (13/125) of all S. aureus isolates and 5% (12/241) of all abscesses were attributed to pvl-positive CA-MRSA. Overall, 77% and 69.9% of CA-MRSA and methicillin-sensitive S. aureus (MSSA) were susceptible to erythromycin, 77% and 74.8% to clindamycin, 100% and 97.1% to minocycline, and 100% and 98.1% to rifampin, respectively. Filipino ethnicity was the only clinical and epidemiologic factor significantly associated with CA-MRSA infection (odds ratio, 14.8; 95% confidence interval, 3.3-70.0; P < 0.001). Pulsed-field gel electrophoresis analysis showed that 6 CA-MRSA isolates belonged to the ST30-HKU100 clone, 5 belonged to the ST59-HKU200 clone, and 1 was singleton. Features of HKU100 isolates include SCCmec type IV, agr3, spa t019, and pan-susceptibility to non-beta-lactam antibiotics. In contrast, HKU200 isolates are characterized by having SCCmec type IV or V, agr4, spa t437, and variable non-beta-lactam susceptibility profiles. The major CA-MRSA spa types were shared by a minority of the MSSA.
