Emergency department use by nursing home residents.

STUDY OBJECTIVE: To describe a community's experience with the use of emergency department services by nursing home residents. METHODS: We performed a retrospective chart review of a population-based cohort of nursing home residents in an urban county in central Georgia with 10 nursing homes (1,300 beds) and 4 hospital-based EDs. All ED visits by nursing home residents during 1995 were analyzed. Demographic data, timing of the visit, chief complaint, tests and treatments, disposition, and financial charges were recorded. Further, we calculated the number of ED visits per 100 nursing home patient-years. RESULTS: A total of 873 nursing home residents made 1,488 ED visits. Mean age was 76.0 years; 66.4% were female, and 55.2% were white. Of the transfers, 42.9% occurred during regular working hours. The most common chief complaints were respiratory symptoms (14.4%), altered mental status (10.1%), gastrointestinal symptoms (9.9%), and falls (8.2%); 101 patients (6.8%) were transferred for malfunction of a gastrostomy tube. The most common laboratory tests were complete blood cell count (69.5%), chest radiograph (52.0%), electrocardiogram (45.0%), urinalysis (42.7%), and determination of electrolytes (42.7%). A total of 42.4% of the ED visits led to admission to the hospital. From the 10 nursing homes, there were 110 ED visits per 100 patient-years. A 3.5-fold difference in ED use among these nursing homes could not be explained by age, gender, or other factors. The average .charge per ED visit was $1,239. CONCLUSION: Elders living in nursing homes are frequently transferred to EDs for costly medical evaluations, and more than 40% of such visits lead to admission to the hospital.

The effect of a physician assistant on the hospitalization of nursing home residents.

OBJECTIVES: To describe the impact of regular visits to a nursing home by a gerontologist physician assistant (PA) on the hospitalization and medical costs of patients. DESIGN: A 6-year case series (1992-1997) incorporating events before and after introduction of a PA in May 1994. The PA visited the nursing home 3 to 4 times per week, provided nearly all of the acute medical care, and alternated routine visits with supervising physicians. SETTING: A 92-bed teaching nursing home in central Georgia. MEASUREMENTS: Demographics of the nursing home population; hospitalizations of residents, including major diagnosis and length of stay; number and site of all resident deaths; costs of physician and PA services and hospital costs. RESULTS: After the introduction of the physician assistant, the number of annual hospital admissions fell by 38.0%, and the total number of hospital days per 1000 patient years fell by 68.6% (from 4170 in 1992 to 1310 in 1997). The number of nursing home visits increased by 62.1%. Annual Medicare-allowed charges for MD and PA services increased by $22,304, but this was more than offset by a decline in hospital DRG reimbursements of $96,043. CONCLUSIONS: The introduction of regular visits to nursing home patients by a physician assistant can reduce hospitalization and medical costs of these frail older people.

Is silent ischemia on the routine admission ECG an important finding?

The authors' objective was to determine if, in the absence of known coronary artery disease, ST-T changes suggestive of silent ischemia on the admission electrocardiogram (ECG) identify a group of patients at high risk for cardiac event or death. A prospective cohort study was undertaken at the university hospital of a tertiary care center. All patients admitted to the hospital during the 5-month study period were screened. The authors found 54 patients with risk factors but no symptoms of coronary artery disease whose admission ECGs showed silent ischemia (ischemia group), and 71 patients with similar risk of coronary artery disease but without admission ECGs showing silent ischemia (control group). Three-week and 6-month incidences of angina, myocardial infarction, and death among patients in the silent ischemia and control groups were compared. Seven (13%) patients in the silent ischemia group had cardiac events or noncardiac death in the subsequent 3 weeks versus one (1%) noncardiac death in the control group (p < 0.02). At 6 months, eight (15%) patients in the silent ischemia group versus two (3%) in the control group had cardiac events (p = 0.02). It is concluded that among patients with risk factors but no symptoms of coronary artery disease, silent ischemia on the admission ECG is associated with an increased likelihood of short-term death or cardiac event.
