Social media not 'clinically addictive;' Jay Bhattacharya, M.D., Ph.D., named interim head of CDC; what patients think about DPC — Morning Medical Update Weekly Recap

Social media not ‘clinically addictive,’ says Instagram CEO

Instagram head Adam Mosseri testified in Los Angeles Superior Court that while social media can be used in ways that feel excessive, he does not consider it a clinical addiction. Comparing heavy Instagram use to being “hooked” on a Netflix show, Mosseri said it’s important to distinguish between addiction and “problematic use.” The testimony came in a closely watched trial alleging that Meta and YouTube designed features such as infinite scroll to foster addictive behavior and harm young users’ mental health. Plaintiffs argue the platforms misled the public about safety, while Meta maintains the apps include safeguards and that protecting minors is consistent with long-term business interests.

NIH Director Bhattacharya to also serve as acting CDC chief

National Institutes of Health (NIH) Director Jay Bhattacharya, M.D., Ph.D., will temporarily lead the Centers for Disease Control and Prevention (CDC) amid a leadership shakeup at the Department of Health and Human Services (HHS), according to administration officials. Bhattacharya, who already oversees the nearly $50 billion NIH, will step in as acting CDC director after HHS Deputy Secretary Jim O’Neill exits the role. The move follows months of turmoil at the CDC, including the firing of former director Susan Monarez and multiple senior resignations tied to vaccine policy disputes. Under federal law, Bhattacharya can serve in the acting role only until late March unless President Trump nominates a permanent replacement.

DPC patients report high access, loyalty in new report

Patients in direct primary care (DPC) practices report strong access, relationships and overall satisfaction, according to a new Hint Health benchmark survey of 1,534 patients across 12 clinics in eight states. Using the Person-Centered Primary Care Measure (PCPCM), respondents gave an overall score of 89%, including 97% for access and 82% for continuity. The survey also found a Net Promoter Score (NPS) of 85 — well above typical health care averages — suggesting high loyalty and willingness to recommend their physicians. Patients who had longer relationships with their doctors reported the highest scores.
