The potential economic value of sputum culture use in patients with community-acquired pneumonia and healthcare-associated pneumonia.
Researchers developed a decision model to determine the economic and clinical value of using sputum cultures in the treatment of community-acquired pneumonia (CAP) and healthcare-associated pneumonia (HCAP) from the hospital perspective under various conditions. They found that, overall, obtaining sputum cultures does not provide significant clinical or economic benefits for CAP or HCAP patients; however, it can reduce costs and shorten overall length of stay under some circumstances. They recommended that clinicians consider their local conditions when making decisions about sputum culture use.

Identifying complexity in infectious diseases inpatient settings: an observation study.
This study sought to identify specific complexity-contributing factors in the infectious disease domain and the relationship with the complexity perceived by clinicians. Its factor analysis revealed three factors explaining 47 percent of total variance, namely task interaction and goals, urgency and acuity, and psychosocial behavior. A linear regression analysis showed no statistically significant association between complexity perceived by the physicians and objective complexity.

Feasibility of population health analytics and data visualization for decision support in the infectious diseases domain: a pilot study.
The objectives of this study were: 1) to explore the feasibility of extracting and displaying population-based information from an actual clinical population's database records, 2) to explore specific design features for improving population display, 3) to explore perceptions of population information displays, and 4) to explore the impact of population information display on cognitive outcomes. It concluded that a population database has great potential for reducing complexity and uncertainty in medicine to improve clinical care.
