A Comparative Study of Community- and Nursing Home-Acquired Empyema Thoracis

JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 11 2007
Ali A. El Solh MD
OBJECTIVES: To compare the clinical presentation, microbiological features, and outcomes of patients with community-acquired empyema (CAE) with those of patients with nursing home-acquired empyema (NHAE). DESIGN: A retrospective observational study. SETTING: Three tertiary care centers. PARTICIPANTS: One hundred fourteen patients admitted from the community and 55 patients transferred from nursing homes. MEASUREMENTS: Baseline sociodemographic information, activities of daily living, Charlson Comorbidity Index score, and clinica, and microbiologic data were obtained. Outcome was assessed at hospital discharge and 6 months postdischarge. RESULTS: Patients admitted from nursing homes had a delayed presentation, with dyspnea, weight loss, and anemia as the predominant manifestation. Patients with CAE presented more acutely, with fever, cough, and chest pain. Anaerobic organisms were more commonly isolated from patients with NHAE. The success rate of nonsurgical intervention was significantly lower for the NHAE patients than for the CAE group (39% vs 63; P=.01). In-hospital mortality was not significantly different between the two groups (NHAE, 18%; CAE, 8%; P=.09). In a Cox regression analysis, preadmission functional status (hazard ratio (HR)=1.26, 95% confidence interval (CI)=1.19,1.4; P<.001) and surgical intervention (HR=0.47, 95% CI=0.24,0.92; P=.03) were the only variables highly correlated with long-term outcome. CONCLUSION: Patients admitted with NHAE have distinctly different clinical and microbiological presentation from that of patients with CAE. Because of the delayed presentation in patients with NHAE, medical treatment alone may be associated with higher rate of failure. Surgical therapy should be considered for selected cases, with the aim of improving long-term survival. [source]

Emergency Department Utilization by Noninstitutionalized Elders

ACADEMIC EMERGENCY MEDICINE, Issue 3 2001

Abstract. Objectives: To the best of the authors knowledge, no nationally representative, population-based study has characterized the proportion of elders using the emergency department (ED) and factors associated with ED use by elders. This article describes the proportion of elder Medicare beneficiaries using the ED and identifies attributes associated with elder ED users as compared with nonusers. Methods: The 1993 Medicare Current Beneficiary Survey was used, a national, population-based, cross-sectional survey of Medicare beneficiaries linked with Medicare claims data. The study population was limited to 9,784 noninstitutionalized individuals aged 66 years or older. The Andersen model of health service utilization was used, which explains variation in ED use through a combination of predisposing (demographic and social), enabling (access to care), and need (comorbidity and health status) characteristics. Results: Eighteen percent of the sample used the ED at least once during 1993. Univariate analysis showed ED users were older; were less educated and lived alone; had lower income and higher Charlson Comorbidity Index scores; and were less satisfied with their ability to access care than nonusers (p < 0.01, chi-square). Logistic regression identified older age, less education, living alone, higher comorbidity scores, worse reported health, and increased difficulties with activities of daily living as factors associated with ED use (p < 0.05). Need characteristics predicted ED use with the greatest accuracy. Conclusions: The proportion of elder ED users is slightly higher than previously reported among Medicare beneficiaries. Need (comorbidity and health status) characteristics predict ED utilization with the greatest accuracy. [source]

Predictors of Toxicity and Toxicity Profile of Adjuvant Chemotherapy in Elderly Breast Cancer Patients

THE BREAST JOURNAL, Issue 4 2009
Praveen Garg MD
Abstract:, Women older than 70 years have been underrepresented in breast cancer adjuvant chemotherapy trials due to concerns about toxicity, safety and tolerance of chemotherapy. The aim of our study was to assess the tolerance of chemotherapy in older women with breast cancer and determine patterns of toxicity including the impact of age, chemotherapy regimen, functional status and comorbid conditions on this toxicity. We retrospectively reviewed the charts of early stage (stages 1 and 2) breast cancer patients older than 70 years from 1998 to 2004. A total of 62 patients, with mean age of 74.3 years, were identified. Chemotherapy was completed in 89% patients. Overall 79% completed chemotherapy without any significant side-effects, dose reductions, or breaks during chemotherapy. Using logistic regression model increasing age was not associated with early termination of chemotherapy (p = 0.19, OR: 0.868, 95% CI: 0.7,1.076). However, increasing age, lower functional status, and higher comorbidity index scores were associated with reduction in dose and breaks in chemotherapy. None of the patients who received pegfilgrastim prophylactically developed high-grade neutropenia. Our study suggests that adjuvant chemotherapy is safe in elderly patients. Older patients with good functional status and low comorbidity index scores tolerate chemotherapy as well as the younger patients. Prophylactic use of pegfilgrastim may reduce occurrence of severe neutropenia and related toxicity such as febrile neutropenia in the elderly patient. [source]
