Background Use of indwelling urinary catheters can lead to complications, most commonly catheter-associated urinary tract infections. Duration of catheterization is the major risk factor. These infections can result in sepsis, prolonged hospitalization, additional hospital costs, and mortality. Objectives To implement and evaluate the efficacy of an intervention to reduce catheter-associated urinary tract infections in a medical intensive care unit by decreasing use of urinary catheters. Methods Indications for continuing urinary catheterization with indwelling devices were developed by unit clinicians. For a 6-month intervention period, patients in a medical intensive care unit who had indwelling urinary catheters were evaluated daily by using criteria for appropriate catheter continuance. Recommendations were made to discontinue indwelling urinary catheters in patients who did not meet the criteria. Days of use of a urinary catheter and rates of catheter-associated urinary tract infections during the intervention were compared with those of the preceding 11 months. Results During the study period, 337 patients had a total of 1432 days of urinary catheterization. With use of guidelines, duration of use was significantly reduced to a mean of 238.6 d/mo from the previous rate of 311.7 d/mo. The number of catheter-associated urinary tract infections per 1000 days of use was a mean of 4.7/mo before the intervention and zero during the 6-month intervention period. Conclusions Implementation of an intervention to judge appropriateness of indwelling urinary catheters may result in significant reductions in duration of catheterization and occurrences of catheter-associated urinary tract infections.

Background Nurses are often responsible for placement of large-bore gastric tubes. Tube misplacement into the lungs is a potential complication with serious sequelae. The reliability of common bedside methods for differentiating between pulmonary and gastric placement has not been acceptable. Objective To compare the accuracy of capnometry (colorimetric indicator of end-tidal carbon dioxide) and air insufflation/auscultation with the accuracy of radiography in detecting the location of gastric tubes. Methods A prospective convenience sample of insertions of Salem sump gastric tubes was studied. Tubes were inserted by nurses according to the unit’s standard procedure, and air insufflation/auscultation, capnometry, and radiography were used to detect the position of the tubes. Results obtained with each of the methods were compared. Results A total of 91 tube placements were studied in 69 patients. No radiographically documented instances of lung placement occurred. Capnometry incorrectly indicated 15 of 91 gastric placements (16%) as placements in the lung. Air insufflation/auscultation incorrectly indicated 5 of 91 gastric placements (5%) as placements in the lung. Conclusions Neither air insufflation nor capnometry is a fail-safe method for determining placement of gastric tubes. Radiography remains the preferred method.

• Background Moral distress is caused by situations in which the ethically appropriate course of action is known but cannot be taken. Moral distress is thought to be a serious problem among nurses, particularly those who practice in critical care. It has been associated with job dissatisfaction and loss of nurses from the workplace and the profession. • Objectives To assess the level of moral distress of nurses in a medical intensive care unit, identify situations that result in high levels of moral distress, explore implications of moral distress, and evaluate associations among moral distress and individual characteristics of nurses. • Methods A descriptive, questionnaire study was used. A total of 28 nurses working in a medical intensive care unit anonymously completed a 38-item moral distress scale and described implications of experiences of moral distress. • Results Nurses reported a moderate level of moral distress overall. Highest levels of distress were associated with the provision of aggressive care to patients not expected to benefit from that care. Moral distress was significantly correlated with years of nursing experience. Nurses reported that moral distress adversely affected job satisfaction, retention, psychological and physical well-being, self-image, and spirituality. Experience of moral distress also influenced attitudes toward advance directives and participation in blood donation and organ donation. • Conclusions Critical care nurses commonly encounter situations that are associated with high levels of moral distress. Experiences of moral distress have implications that extend well beyond job satisfaction and retention. Strategies to mitigate moral distress should be developed and tested.

• Background Underfeeding of patients reliant on enteral tube feedings most likely is due primarily to interruptions in the infusions. Strategies to improve energy intake require an understanding of such interruptions and associated outcomes. • Objectives To compare daily energy intake with goal energy intake; to ascertain frequency, duration, and reasons for interruptions in feedings; and to determine occurrences of feeding intolerance. • Methods A prospective, descriptive study of a convenience sample of patients admitted during a 3-month period to a medical intensive care unit. Patients were included who were expected to receive continuous enteral tube feedings for at least 48 hours. Patients were studied until discontinuation of feedings, discharge from the unit, or death. • Results Thirty-nine patients were studied for 276 feeding days. Patients received a mean of 64% of goal energy intake. Mean length of interruptions in feeding was 5.23 hours per patient per day. Interruptions for performance of tests and procedures accounted for 35.7% of the total cessation in feeding time. Next most time-consuming interruptions occurred with changes in body position (15%), unstable clinical conditions (13.5%), high gastric residual volume (11.5%), and nausea and vomiting (9.2%). Patients had diarrhea 105 (38%) of 276 feeding days. Gastric residual volumes exceeded 150 mL on 28 measurements in 11 patients. Five patients experienced episodes of nausea and vomiting. Four patients experienced an episode of feeding aspiration. • Conclusions Precautionary interruptions in enteral feedings to decrease presumed risk of aspiration occurred frequently and resulted in underfeeding. Episodes of vomiting and of aspiration were uncommon.
