Elective intrahospital admissions versus acute interhospital transfers to a surgical intensive care unit: cost and outcome prediction.
After a decade of intense fiscal scrutiny, appropriate utilization of intensive care resources remains controversial. In particular, the financial impact of patients transferred to a tertiary surgical intensive care unit (SICU) from a community hospital (interhospital) is unknown, especially when compared with elective (intrahospital) SICU admissions admitted from the tertiary center itself. We prospectively studied outcome and costs in 82 consecutive tertiary SICU admissions. ⋯ When stratified by APACHE II score, acute transfers had twice the mortality for equivalent APACHE II scores (p less than 0.05). Acute transfer patients with APACHE II scores greater than 19 had an 89% mortality; those nonsurvivors cost $128,652 each. From these results we conclude the following: (1) Acute transfer patients have a significantly elevated mortality when compared with elective intrahospital admissions with equivalent APACHE II day-1 scores; (2) patients transferred acutely to tertiary SICUs are significantly more costly, irrespective of outcome; (3) admission source (elective vs. acute transfer) should be seriously considered when evaluating patient outcome and cost in a SICU.

Colloid oncotic pressure (COP) and fluid shifts were studied in 43 septic (SS) patients and 33 injured (HS) patients (ISS = 48.2). During maximal postresuscitation fluid retention, plasma volume (PV/RISA), red cell volume (RBC/51Cr), inulin space (ECF), and COP were measured. Interstitial space (IFS), PV/IFS ratio, and correlation coefficients (r) were calculated. ⋯ Expansion of IFS in SS patients correlated (r = -0.76, p less than 0.02) with reduced plasma COP; this was not seen in HS patients (r = -0.09, p less than 0.35). In contrast, plasma COP correlated (r = 0.72, p less than 0.001) with PV/RISA in HS patients but not in SS patients (r = 0.09, p greater than 0.35). We conclude: (1) SS patients with greater IFS expansion that correlates with reduced plasma COP likely have increased capillary permeability; and (2) HS patients with less IFS expansion that does not correlate with reduced plasma COP likely have maintained capillary permeability with altered IFS matrix configuration causing reduced protein exclusion.

The role of CT scanning as an adjunct to plain roentgenograms of the cervical spine was reviewed in acutely injured blunt trauma patients. Following institution of a protocol to evaluate the cervical spine in all blunt trauma patients, 179 patients underwent CT scanning of their cervical spine. This was performed for patients whose x-ray findings were positive, for patients with plain x-ray films suggestive of a pathologic condition, for patients with plain x-ray films that did not reveal all of the cervical vertebrae, and for patients who had persistent pain or neurologic deficits despite normal plain x-ray films. ⋯ A false-positive rate of 28% and a false-negative rate of 1.5% were found for plain roentgenograms. Computed tomographic scans detected 98% of the injuries in our study and when combined with a three-view plain x-ray series of the cervical spine, 100% of cervical spine injuries were detected. Computed tomographic scanning as an adjunct to plain x-ray films of the cervical spine is a highly accurate and expedient modality to clear the cervical spine of blunt trauma patients.

The efficacy of resuscitative emergency room thoracotomy (ERT), particularly in blunt injury, has been questioned. Wide application of the procedure may not be cost effective. The risk of exposure and lethal infection to medical personnel during ERT is considerable. ⋯ Screening for HIV and hepatitis could be documented in only two patients; both were negative. Liberal performance of ERT has dismal results, incurs monetary loss, and affords a greater potential for exposure to lethal infection. Emergency room thoracotomy is justified only when vital signs or a resuscitatible cardiac rhythm are present in the field or ER and deteriorate shortly before thoracotomy.(ABSTRACT TRUNCATED AT 250 WORDS)
