Quality Improvement for Quality Improvement Studies
1/2/2018
Grady D, Redberg RF, O’Malley PG.
ver resumen
At JAMA Internal Medicine, we receive many manuscripts describing studies designed to improve health care quality, safety, or value. We applaud these efforts, as we strongly believe that changes in health care delivery and process should be driven by evidence. We also believe, however, that it is time to raise the bar on the methods, analysis, and reporting of quality improvement studies, as well as the threshold for those that are worthy of publication in this journal.

The Renal Challenge With Left Ventricular Assist Device Therapy
1/2/2018
Thomas SS, Zern EK, D’Alessandro DA.
ver resumen
Nearly 2 decades after the seminal REMATCH trial first demonstrated a marginal survival benefit in transplant-ineligible patients treated with an implantable left ventricular assist device (LVAD), contemporary 1-year LVAD survival exceeds 80%. With improved outcomes and quality of life, LVAD use has proliferated, with more than 15 000 implantations since 2006 and an annual implantation rate exceeding 2000 per year across an ever-growing number of implanting centers. While most current LVADs are implanted as a bridge to cardiac transplantation, an increasing proportion of patients with end-stage heart failure are consenting to indefinite mechanical circulatory support (MCS) therapy. With an increasing prevalence of advanced heart failure in an aging population, this trend is expected to continue.

Evolution of Herpes Zoster Vaccines and Their Economic Value
1/2/2018
Najafzadeh M.
ver resumen
Herpes zoster (HZ) affects almost 1 in 3 adults in the United States during their lifetime. The disease often causes severe pain that may last for a few weeks, with substantial influence on individuals’ quality of life, daily activities, and work. Some patients continue to experience debilitating pain for more than a year, a complication that is known as postherpetic neuralgia (PHN). Serious cases can involve the eyes and central nervous system disease.
