Continuously improving patient care: practical lessons and an assessment tool from the National ICU Study.

Pressure for hospitals to maintain quality while lowering cost or provide greater quality at a given level of cost is particularly critical in intensive care services for which it is increasingly difficult to match revenues with costs, given reimbursement limits. At the same time, twofold to threefold differences in intensive care unit risk-adjusted mortality have been reported. This article provides a model for thinking about continuous improvement of intensive care services, draws on the National ICU Study to identify fundamental organizational and managerial processes associated with better performance, and offers a validated assessment instrument to be used as a tool for continuous improvement.

Communication

Double-blind randomized multicenter study comparing Maalox TC tablets and ranitidine in healing of duodenal ulcers.

The efficacy of ranitidine 150 mg twice daily and Maalox TC three tablets four times daily were compared in patients with endoscopically confirmed duodenal ulcer. Seventy-nine patients were randomly allocated to double-blind, double-dummy treatment, stratified for smokers. Endoscopy was repeated after four weeks. Those unhealed continued treatment for a further two weeks before final endoscopy. Per protocol analysis in 53 patients showed ulcer healing rates at week 4 and at weeks 4 and 6 combined of 78 and 89% on Maalox TC, and of 81 and 91% on ranitidine, respectively. The same analysis gave overall healing rates of 81% in smokers and 100% in nonsmokers, irrespective of treatment. Both treatments provided early ulcer pain relief. Diarrhea was a commoner side effect in patients on Maalox TC. The study showed Maalox TC and ranitidine were equally effective in healing duodenal ulceration.

Organizational assessment in intensive care units (ICUs): construct development, reliability, and validity of the ICU nurse-physician questionnaire.

Health Services Research has a growing need for reliable and valid measures of managerial practices and organizational processes. A national study of 42 intensive care units involving over 1,700 respondents provides evidence for the reliability and validity of a comprehensive set of measures related to leadership, organizational culture, communication, coordination, problem solving-conflict management and team cohesiveness. The data also support the appropriateness of aggregating individual respondent data to the unit level. Implications for further research are discussed.

Analysis of Variance

Carcinoembryonic antigen and alpha 1-fetoprotein in ulcerative colitis and regional enteritis.

Sera were collected from 108 patients with inflammatory bowel disease and assayed for carcinoembryonic antigen (CEA) and alpha(1)-fetoprotein (AFP). Seven (14%) of 51 patients with ulcerative colitis had a positive test for CEA and one of these had associated carcinoma of the colon. Ten (19%) of 52 patients with regional enteritis were also seropositive. The sera of 4 (9%) of 47 patients with ulcerative colitis and 2 (5%) of 41 patients with regional enteritis contained small amounts of AFP. Of two unclassified patients one had a positive CEA and the other a positive AFP. No serum was positive for both CEA and AFP. In addition, multiple samples were available for sequential analysis in eight CEA-positive patients but there was no apparent relationship between seropositivity and disease activity. Continued follow-up is now in progress to determine the significance of detectable fetal antigen levels in inflammatory bowel disease.
