A model for selecting a clinical laboratory information system. A four-phase process.

Laboratory information systems (LISs) have become an essential part of an efficient and effective laboratory. In the past, selecting an LIS was a relatively simple procedure because there were only a few candidates to select from. Now, however, selecting an LIS from the myriad available has become a time-consuming and complex process. This article presents a multi-attribute utility (MAU) method for selecting an LIS. This MAU method has four phases: identifying LIS vendors and disseminating requests for proposals (RFPs), analyzing RFP responses and selecting the top three vendors, validating responses of the top three vendors, and selecting a primary vendor and preparing a formal recommendation. By following this four-phase process, laboratories will simplify the complex LIS selection process and increase their chances of selecting the best LIS for their needs.

Total parenteral nutrition and the patient with chronic obstructive pulmonary disease.

Patients with chronic obstructive pulmonary disease (COPD) are generally malnourished. A catabolic state predisposes these patients to infection and a subsequent increase in mortality. Nutritional support may be mandatory to prevent visceral deterioration, but side effects of total parenteral nutrition (TPN) feeding can be harmful to patients with COPD. The use of glucose concentrates causes an increase of CO2, creating a metabolic demand for O2 that usually cannot be met. Specific formulas of TPN for COPD patients, using lipids for calories and limiting glucose, lower the respiratory quotient. There still remains a dilemma for adequate nutritional repletion, however, because all nutrients alter respiratory demand. Patients in acute respiratory failure or those requiring mechanical ventilation create a vital challenge for the health care provider.
