This study assessed the incidence, etiology, and consequences of ventilator-associated pneumonia in 1,000 consecutive patients admitted in a medical-surgical intensive care unit (ICU). A total of 264 patients were submitted to mechanical ventilation (MV) for more than 48 hours. Fifty-eight (21.9 percent) patients developed a bacterial pneumonia after a mean of 7.9 days (range, 2 to 40 days) of MV. ⋯ The mortality rate in the pneumonia group was 42 percent; this percentage is similar to mortality rate among MV patients without pneumonia (37 percent). We conclude that nosocomial pneumonia is a frequent complication of MV in the medical-surgical ICU. Ventilator-associated pneumonia does not appear to increase fatality in critically ill patients with a high mortality rate (38 percent); however, it significantly prolongs the length of stay in the ICU for survivors.

Comparative Study
A comparison of intensive care unit care of surgical patients in teaching and nonteaching hospitals.
Three hundred forty-eight teaching (TH) and 282 nonteaching (NTH) hospitals were surveyed to determine how intensive care unit (ICU) care is delivered to surgical patients and current views on surgical critical care. Teaching hospitals were more likely than NTHs to have a separate surgical ICU (92% versus 37%), a dedicated ICU service/physician (37% versus 7%), and a surgeon as director of the ICU (67% versus 29%). All THs and 33% of NTHs provided 24 hour in-house coverage for the ICU. ⋯ Many (THs, 45%; NTHs, 33%) thought that surgeons are willingly relinquishing ICU care. Surgeons continue to desire responsibility for their patients in the ICU and most prefer ICU service involvement provided by surgeons. This discrepancy between what is practiced and what is desired, along with proposed changes in reimbursement for surgery and the recent definition of critical care as an essential part of surgery, may stimulate greater involvement of surgeons in critical care.

The authors describe the first year of operation of a nurse-managed intensive care unit (ICU). Concerned with the problems, costs, and inadequacies of caring for long-term patients in traditional ICUs, nurse administrators designed a special care unit that incorporates a physical design facilitating family involvement and rehabilitative care, registered nurse case management, and a shared governance management philosophy. Compared with traditional ICUs, the effectiveness of the special care unit is tested in terms of patient and nurse outcomes. Implications of this innovation for health-care delivery systems and the nursing profession are discussed.

Intensive care unit patients with acquired immunodeficiency syndrome and Pneumocystis carinii pneumonia: suggested predictors of hospital outcome.
To define our ICU experience with AIDS patients, Pneumocystis carinii pneumonia, and respiratory failure, and to delineate factors predictive of hospital survival. ⋯ When dealing with AIDS/P. carinii pneumonia/ICU patients, it is not possible to distinguish who will survive to hospital discharge based on information routinely available before ICU admission. Those patients with the greatest chance of survival demonstrate a significant decrease in the required level of respiratory support within the first 4 days of ICU care. The presence of a metabolic acidemia (pH less than 7.35 and base deficit greater than 4 mEq/L), at any time during the ICU course, is a poor prognostic sign. We suggest that such objective variables should be included in the development of any new outcome predictor model for this group of ICU patients.

Cardiopulmonary resuscitation (CPR) is often performed in modern critical care units, but its efficacy has not been evaluated in this setting. It is important to evaluate CPR in critical care units because these patients often have multisystem disorders and suffer from diseases reported to carry a poor outcome after CPR. Inappropriate resuscitation of patients in this setting results in increased cost of care (both financial and emotional), with little tangible benefit. ⋯ The only arrest condition found to be independently associated with outcome following CPR was the duration of resuscitative effort (p less than 0.01). The patients who were successfully resuscitated but died before discharge were not different from the patients who were not successfully resuscitated in any parameter that we evaluated. These results demonstrate that CPR can be successful in the MICU and that there are prearrest and arrest parameters which are useful in identifying those patients most likely to benefit from CPR in the critical care setting.
