Patient outcomes for the chronically critically ill: special care unit versus intensive care unit.

The purpose of this study was to compare the effects of a low-technology environment of care and a nurse case management case delivery system (special care unit, SCU) with the traditional high-technology environment (ICU) and primary nursing care delivery system on the patient outcomes of length of stay, mortality, readmission, complications, satisfaction, and cost. A sample of 220 chronically critically ill patients were randomly assigned to either the SCU (n = 145) or the ICU (n = 75). Few significant differences were found between the two groups in length of stay, mortality, or complications. However, the findings showed significant cost savings in the SCU group in the charges accrued during the study period and in the charges and costs to produce a survivor. The average total cost of delivering care was

Survival experience of chronically critically ill patients.

The impact of age on admission practices and pattern of care were examined in 599 admissions to a medical intensive care unit (MICU) and 290 patients on the conventional medical care divisions of the same hospital. Four age groups were compared: under 55, 55 to 64, 65 to 74, and 75 years of age and over. Severity of illness and prior health were assessed using the Acute Physiology Score (APS) and the Chronic Health Evaluation (CHE) instruments. Resource utilization was assessed using the Therapeutic Intervention Scoring System (TISS) and hospital charges.

To assess the relative value of healthcare programs, technologic innovations, and clinical decisions, policymakers are searching for ways to evaluate cost-effectiveness. What constitutes cost-effectiveness and how should it be measured? The authors discuss ways in which the cost-effectiveness of clinical programs can be measured and describes various methods of assessing both costs and effectiveness. Comparison of the cost-effectiveness of a nurse managed special care unit with that of traditional intensive care units illustrates some of these methods.

Do-not-resuscitate practices in the chronically critically ill

Intensive care unit (ICU) patients were randomly assigned to either a traditional ICU or a special care unit (SCU) for chronically critically ill patients. The SCU used a low-technology, family-oriented environment, nursing case management, no physician house staff, and a shared governance model. In comparison, the ICU used high technology, limited family visiting, primary care nursing, and a bureaucratic management model. The survival experience of chronically critically ill patients in the two environments during hospitalization, as well as after hospital discharge, was examined. Using survival analytic techniques, the 1-year cumulative mortality for all patients in the study was found to be 59.9%. Risk of death was significantly lower after discharge than during hospitalization. Similar mortality experiences were found for SCU and ICU patients. Thus, the high-technology ICU environment did not produce better outcomes than the SCU environment.

Age differences in survival outcomes and resource use for chronically critically ill patients

Papillomas are rare tumors of the respiratory tract, which are usually considered benign. We studied a male patient with adult onset of squamous papillomatosis involving both the trachea and the bronchi, with malignant degeneration. When we obtained specimens bronchoscopically, only the bronchial lesions showed carcinomatous changes. Thoracotomy demonstrated carcinoma in the tracheal lesion as well. We conclude that transbronchoscopic biopsy may be inadequate in the evaluation of papillomatosis.

OBJECTIVES To determine the frequency of do-not-resuscitate (DNR) orders in the chronically critically ill; to identify the differences in clinical and demographic characteristics of chronically critically ill patients who have DNR orders and those who do not; to identify the differences in the cost of care between patients with and without DNR orders; and to identify the differences in DNR practices between an experimental special care unit and the traditional intensive care unit (ICU). DESIGN Randomized, prospective design with a block randomization scheme. SUBJECTS Two hundred twenty patients who met the following eligibility criteria for enrollment in a parent study of the special care unit: an ICU stay of at least 5 days, an absence of pulmonary artery monitoring, an absence of frequent titration of intravenous vasopressors, an Acute Physiology and Chronic Health Evaluation II score of less than 18, and a Therapeutic Intervention Scoring System score of less than 39. SETTING A large, urban academic medical center. MEASURES Clinical and demographic variables describing the study populations, mental status, and timing of DNR orders, mortality rates, and cost of hospitalization. RESULTS There was no difference in the frequency of DNR orders between the special care unit versus the intensive care unit--although patients in the special care unit had a longer interval between hospital admission and initiation of the DNR order. DNR patients differed from non-DNR in that they were older, less likely to be married, and had a higher Acute Physiology and Chronic Health Evaluation II score on admission to the study. The mortality rate in the DNR group was 71% versus 6% in the non-DNR group. There was no difference in total costs. DNR patients were also more likely to have an impaired mental status on admission, and more likely to have deterioration in mental status by the time of discharge than the non-DNR patients.

An Enlarging Solitary Mass in an Asymptomatic Patient

PURPOSE Chronically critically ill (CCI) patients use a disproportionate amount of resources, yet little research has examined outcomes for older CCI patients. The purpose of this study was to compare outcomes (mortality, disposition, posthospital resource use) between older (> or =65 years) and middle-aged (45-64 years) patients who require more than 96 hours of mechanical ventilation while in the intensive care unit. METHODS Data from 2 prospective studies were combined for the present examination. In-hospital as well as posthospital discharge data were obtained via chart abstraction and interviews. RESULTS One thousand one hundred twenty-one subjects were enrolled; 62.4% (n = 700) were older. Older subjects had a 1.3 greater risk for overall mortality (from admission to 4 months posthospital discharge) than middle-aged subjects. The Acute Physiology Score (odds ratio [OR], 1.009), presence of diabetes (OR, 2.37), mechanical ventilation at discharge (OR, 3.17), and being older (OR, 2.20) were statistically significant predictors of death at 4 months postdischarge. Older subjects had significantly higher charges for home care services, although they spent less time at home (mean, 22.1 days) than middle-aged subjects (mean, 31.3 days) (P = .03). CONCLUSION Older subjects were at higher risk of overall mortality and used, on average, more postdischarge services per patient when compared with middle-aged subjects.

Trial of a Disease Management Program to Reduce Hospital Readmissions of the Chronically Critically Ill

We compared the efficacy of terbutaline with that of metaproterenol, isoproterenol, and placebo aerosols in 16 asthmatic patients. Terbutaline, metaproterenol, and isoproterenol produced equivalent improvements in flow rates. At 5 hr, the effect of terbutaline on tests of small airways, FEF25%–75% and FEF50%, was greater (p < 0.05) than that of metaproterenol and isoproterenol. Terbutaline produced no significant change of heart rate or blood pressure.
