Hospitals engaged in both public reporting and pay for performance achieved modestly greater improvements in quality than did hospitals engaged only in public reporting. Additional research is required to determine whether different incentives would stimulate more improvement and whether the benefits of these programs outweigh their costs.

The increase in the number of hospitalizations for severe sepsis coupled with declining in-hospital mortality and declining geometric mean cost per case may reflect improvements in care or increases in discharges to skilled nursing facilities; however, these findings more likely represent changes in documentation and hospital coding practices that could bias efforts to conduct national surveillance.

Clinically inapparent adrenal masses are incidentally detected after imaging studies conducted for reasons other than the evaluation of the adrenal glands. They have frequently been referred to as adrenal incidentalomas. In preparation for a National Institutes of Health State-of-the-Science Conference on this topic, extensive literature research, including Medline, BIOSIS, and Embase between 1966 and July 2002, as well as references of published metaanalyses and selected review articles identified more than 5400 citations. Based on 699 articles that were retrieved for further examination, we provide a comprehensive update of the diagnostic and therapeutic approaches focusing on endocrine and radiological features as well as surgical options. In addition, we present recent developments in the discovery of tumor markers, endocrine testing for subclinical disease including autonomous glucocorticoid hypersecretion and silent pheochromocytoma, novel imaging techniques, and minimally invasive surgery. Based on the statements of the conference, the available literature, and ongoing studies, our aim is to provide practical recommendations for the management of this common entity and to highlight areas for future studies and research.

Viral influenza is a seasonal infection associated with significant morbidity and mortality. In the United States more than 35,000 deaths and 200,000 hospitalizations due to influenza occur annually, and the number is increasing. Children aged less than 1 year and adults aged more than 65 years, pregnant woman, and people of any age with comorbid illnesses are at highest risk. Annual vaccination is the cornerstone of prevention, but some older patients may derive less benefit from immunization than otherwise fit individuals. If started promptly, antiviral medications may reduce complications of acute influenza, but increasing resistance to amantadine and perhaps neuraminidase inhibitors underscores the need for novel prevention and treatment strategies. Pulmonary complications of influenza are most common and include primary influenza and secondary bacterial infection. Either may cause pneumonia, and each has a unique clinical presentation and pathologic basis. Staphylococcus aureus, including methicillin-resistant strains, is an important cause of secondary bacterial pneumonia with high mortality. During influenza season, treatment of pneumonia should include empiric coverage for this pathogen. Neuromuscular and cardiac complications are unusual but may manifest in persons of any age.

BACKGROUND: Internet-based social networking tools that allow users to share content have enabled a new form of public reporting of physician performance: the physician-rating website. OBJECTIVE: To describe the structure and content of physician-rating websites and to assess the extent to which a patient might find them valuable. METHODS: We searched Google for websites that allowed patients to review physicians in the US. We included websites that met predetermined criteria, identified common elements of these websites, and recorded website characteristics. We then searched the websites for reviews of a random sample of 300 Boston physicians. Finally, we separately analyzed quantitative and narrative reviews. RESULTS: We identified 33 physician-rating websites, which contained 190 reviews for 81 physicians. Most reviews were positive (88%). Six percent were negative, and six percent were neutral. Generalists and subspecialists did not significantly differ in number or nature of reviews. We identified several narrative reviews that appeared to be written by the physicians themselves. CONCLUSION: Physician-rating websites offer patients a novel way to provide feedback and obtain information about physician performance. Despite controversy surrounding these sites, their use by patients has been limited to date, and a majority of reviews appear to be positive.

NEUMONIA IS A LEADING CAUSE of morbidity and mortality among US adults, resulting in more than 1 million annual hospital admissions and accounting for more than $10.5 billion in aggregate costs. 1,2 Given its public health significance, pneumonia has been the target of quality improvement activities for nearly 2 decades. This began with the publication of clinical practice guidelines in the early 1990s, 3 was followed by a series of statewide and national quality improvement initiatives, 4 and more recently has included public reporting and pay-for-performance programs led by the Joint Commission and the Centers for Medicare & Medicaid Services (CMS) and other payers. 5,6 These efforts have been associated with favorable trends in adherence to recommended processes of care, 7-10 including the choice and timely administration of antibiotics. At the same time, several epidemiologic analyses have reported that survival among pneumonia patients appears to be improving, suggesting that clinical advances, improvements in health care quality, or both are having beneficial effects. 11-14 Although the decline in pneumonia mortality may reflect real improvements in clinical outcomes, in the absence of any For editorial comment see p 1433.

Influenza is a seasonal viral infection associated with significant morbidity and mortality. In 2009, a novel H1N1 influenza A virus emerged and has been classified as a pandemic. In contrast to seasonal influenza, severe disease from pandemic H1N1 seems concentrated in older children and young adults, with almost no cases reported in patients older than 60 yrs. Although patients with underlying cardiopulmonary disease remain at risk, most complications have occurred among previously healthy individuals, with obesity and respiratory disease as the strongest risk factors. Pulmonary complications are common. Primary influenza pneumonia occurs most commonly in adults and may progress rapidly to acute lung injury requiring mechanical ventilation. Secondary bacterial infection is more common in children. Staphylococcus aureus, including methicillin-resistant strains, is an important cause of secondary bacterial pneumonia with a high mortality rate. Treatment of pneumonia should include empirical coverage for this pathogen. Neuromuscular and cardiac complications are unusual but may occur.
