Community-acquired pneumonia (CAP) is responsible for an average of 4.5 million visits annually to physicians' offices, emergency departments, and outpatient clinics. However, there have been few studies using national data on the costs of treating CAP. Without such data, it is difficult to assess whether new therapies and treatment strategies are needed to improve patient outcomes. ⋯ Inpatient physician service costs were $305 million and $192 million for the > or =65 and <65 groups, respectively. Based on 1.1 million outpatient office visits for those aged > or =65 years and 3.3 million visits for those aged <65, total outpatient costs were $119 million and $266 million, respectively. Given the overwhelming cost burden for CAP in the hospital setting, any new therapy that allows patients to be treated in the outpatient setting could result in significant savings, especially for patients aged > or =65 years.

Clinical TrialWeight-based heparin dosing: clinical response and resource utilization.
The objective of this study was to assess a weight-based heparin (WBH) nomogram (80-U/kg bolus, 18-U/kg-per-hour initial infusion) and determine its clinical performance and impact on resource utilization. All patients treated with heparin for venous thromboembolism or unstable angina during a 15-week study period were included in this retrospective, chart-review study. Three groups were identified: patients treated with WBH, patients whose regimen deviated from the weight-based nomogram (DEV), and matched historical controls (HCs). ⋯ Resource utilization was significantly different between the WBH and HC groups in terms of nursing interventions at 48 to 72 hours. We concluded that WBH rapidly drives patients' aPTT response above the therapeutic threshold for heparin; however, prudent adjustment of the initial infusion rate is necessary to avoid a supratherapeutic aPTT response. Our data support a nomogram with an initial infusion rate of 15 U/kg per hour.
