Most adults with community-acquired pneumonia are treated as outpatients. Despite this, the majority of studies regarding community-acquired pneumonia have been in hospitalized patients only and may not be applicable to an ambulatory population. This review critically examines the literature regarding the diagnosis, cause, appropriate patient selection, and treatment of nonhospitalized adults with community-acquired pneumonia, including human immunodeficiency virus-infected individuals. ⋯ Viral, mycoplasmal, and chlamydial agents are among the most common pathogens encountered in individuals treated as outpatients, although much variability exists. Many oral antibiotic trials for community-acquired pneumonia have been published, but shortcomings in study design limit their clinical applicability. A treatment algorithm is offered, using the best available data.

Peripherally inserted central catheterization is a relatively new approach for intravenous therapy in acute-care hospitals. Few studies are available on peripherally inserted central catheters (PICCs) used in adult patients in an acute-care setting. We examine the natural history and outcome of PICC use in our hospital. ⋯ Based on our study, we conclude that the PICC provides a reasonable and safe alternative to other centrally placed venous devices. In addition, the convenience of maintaining a PICC compared with peripheral intravenous access makes this an attractive method for in-hospital use.

Randomized Controlled Trial Clinical Trial
A case manager intervention to reduce readmissions.
Acute hospitalizations represent substantial financial liability to closed health care systems. Among hospitalized patients, those with repeated admissions are high-cost users. Most managed care plans employ case management to control hospital use. This technique attempts to detect and fulfill unmet medical and social needs, intensify postdischarge care, identify and mobilize effective community services, and enhance primary care access. Despite the popularity of case management to control hospital use, few trials have examined its efficacy. ⋯ Frequent contacts for education, care, and accessibility by case managers using protocols were ineffective in reducing nonelective readmissions.

Due to the hormonal and hemodynamic alterations inherent in the surgical experience, acute renal failure is common during the perioperative period. Acute renal failure occurs in 5% of hospital admissions, and the surgical setting is the second most common cause of inpatient acute renal failure. Because this setting has the highest mortality for acute renal failure, recognition of high-risk patients is essential for careful monitoring and prophylactic measures. ⋯ Patients with severe chronic renal failure or end-stage renal disease are at significant risk for development of complications during the perioperative period, due both to renal and nonrenal reasons. Hyperkalemia, infections, arrhythmias, and bleeding commonly occur in these patients during the perioperative period. This population has a reasonable surgical mortality for both general and cardiac surgery, but the extremely high morbidity warrants careful perioperative monitoring and care.

Randomized Controlled Trial Comparative Study Clinical Trial
Use of a standardized heparin nomogram to achieve therapeutic anticoagulation after thrombolytic therapy in myocardial infarction. TIMI 4 investigators. Thrombolysis in Myocardial Infarction.
The recently completed Thrombolysis in Myocardial Infarction (TIMI) 4 Study compared three thrombolytic treatment regimens for acute myocardial infarction. The treatment arms included front-loaded recombinant tissue plasminogen activator (rtPA), anistreplase (APSAC), or both, in conjunction with an intravenous bolus of 5000 U of heparin, followed by 1000 U/h. To facilitate anticoagulation, a heparin nomogram was developed to maintain the therapeutic activated partial thromboplastin time at 1 1/2 to 2 times the control value. ⋯ The use of a heparin nomogram provided improved anticoagulation in patients treated with thrombolytic therapy for myocardial infarction. Weight- and age-adjusted heparin dosing may provide further improvement in anticoagulation with heparin therapy. Our findings support the need for frequent monitoring of the activated partial thromboplastin time and for a standardized approach to adjusting the heparin dosage.
