Only in the world of medicine would Dr. Vivian Lee’s question have seemed radical. She wanted to know: What do the goods and services provided by the hospital system where she is chief executive actually cost? ... No one on Dr. Lee’s staff at the University of Utah Health Care could say what a minute in an M.R.I. machine or an hour in the operating room actually costs. They chuckled when she asked. But now, thanks to a project Dr. Lee set in motion after that initial query several years ago, the hospital is getting answers, information that is not only saving money but also improving care.

Two years ago, researchers in a clinical trial involving oxygen levels for the tiniest premature babies were accused by a federal watchdog agency of not properly disclosing the risks to families who participated. What followed was extensive public scrutiny of the trial, called Support, and soul-searching in the research community about how best to obtain informed consent from participants. Some families sued, arguing that their babies suffered serious injuries as a result of their treatment. But last month, a federal judge threw out the suit .... Last week, the editors of a prestigious medical journal wrote that the decision showed that the trial was solid to begin with. ... But some bioethicists disagreed. (Tavernise, 9/7)

If things are a bit tense in your doctor's office come Oct. 1, some behind-the-scenes red tape could be to blame. That's the day when the nation's physicians and hospitals must start using a massive new coding system to describe your visit on insurance claims so they get paid. Today, U.S. health providers use a system of roughly 14,000 codes to designate a diagnosis, for reimbursement purposes and in medical databases. To get more precise, the updated system has about 68,000 codes, essentially an expanded dictionary to capture more of the details from a patient's chart. (Neergaard, 9/7)

Board certification of physicians has grown into a big business. What was once a one-time exam has slowly expanded to an ongoing and time-consuming process that includes recertification exams every decade and a near continuous stream of online learning modules. It’s also gradually become a multi-million dollar industry that includes fees, study materials and prep courses. Many doctors claim it’s an expensive waste of time, and now some of them are challenging the business of board certification. (Cuda Kroen, 9/7)

The idea of better integrating primary care and behavioral health has been talked about for years by health care experts as a way to both improve health outcomes and save money. Actually bringing the two fields together has lagged, stymied by a host of barriers that include differences in the way the two fields operate, differing payment systems, a lack of funding for the initiatives, and concerns about sharing information between behavioral health and medical providers. But some experts say there appears to be momentum toward integration. (Levin Becker, 9/8)

They bombard your TV day after day: ads for drugs to treat arthritis, diabetes, depression and countless other maladies, hour after hour, around the clock. There's the elephant sitting on a man's chest, touting Spiriva for chronic obstructive pulmonary disorder. If you think you're seeing more of them every year, you're right. Last year, drugmakers spent $4.5 billion on such advertising, a 30 percent jump from 2012, according to Kantar Media, a market research firm that specializes in media consumption. (Russell, 9/4)

For her next lesson, the teacher, a petite, dark-haired woman named Anna C. Sosa, shrugs off her red robe, kicks her striped socks into the footrests and steels herself for yet another potentially disastrous pelvic exam. ... Sosa is a gynecological teaching associate, and she holds one of modern medicine’s most awkward jobs, using her body to guide med students through some of its most delicate, dreaded exams. Every week, she lies back for dozens of the next medical generation’s first pelvic and breast screenings, steering gloved fingers through the mysteries of her own anatomy and relaying the in-depth feedback they’ll need out in the wild.
