+# AI-defined case routing prevents trainees from developing threshold-setting skills required for independent practice
+
+The paper notes that 'only human experts can revise the thresholds for case prioritization'—but this statement reveals a deeper problem: AI defines what humans see in the first place. When trainees are trained under an AI threshold system, they encounter only the cases the AI routes to them. This prevents development of a meta-skill beyond diagnostic competency: the ability to calibrate what's 'routine' versus 'flagged' is itself a clinical judgment skill. Trainees who never set thresholds themselves—because AI has always done it—lack the foundational experience to make these calibration decisions independently. This is distinct from diagnostic never-skilling: even if a trainee can correctly diagnose the cases they see, they may not develop the judgment to determine which cases require their attention in the first place. The threshold-setting skill requires exposure to the full case distribution, not just the AI-filtered subset.

+# AI-integrated cervical cytology screening reduces trainee exposure to routine cases creating never-skilling risk for foundational pattern recognition skills
+
+AI automation in cervical cytology screening targets 'routine processes, such as initial screenings and pattern recognition in straightforward cases' for efficiency gains. However, these routine cases are precisely where trainees develop foundational pattern recognition skills. As AI handles large volumes of routine cervical screens, trainees see fewer cases across the full spectrum of findings. The paper notes this creates a risk where reduced case exposure prevents development of 'diagnostic acumen necessary for independent practice.' This is a structural never-skilling mechanism: the skill deficit won't manifest until trainees become independent practitioners facing edge cases without foundational grounding. The concern is particularly acute because AI may perform well in aggregate but fail on rare variants—exactly the cases humans need exposure to during training to handle them later. Unlike deskilling (where experienced practitioners lose existing skills), never-skilling affects trainees who never acquire the baseline competency in the first place.

 # Federal GLP-1 expansion programs reproduce the access hierarchy at the program design level, not just through market dynamics
 
 The Medicare GLP-1 Bridge program demonstrates that the GLP-1 access inversion operates at the program design level, not just the market level. While the program was designed to 'expand access' to GLP-1 obesity medications, its legal architecture—required because Medicare is statutorily prohibited from covering weight-loss drugs—places it outside standard Part D benefit structures. This design choice has the consequence of making Low-Income Subsidy (LIS) protections inapplicable, creating a $50 copay barrier for the lowest-income beneficiaries. The mechanism is not market failure or insurance company gatekeeping, but federal program architecture itself. The program's eligibility criteria are inclusive (BMI ≥35 alone, or ≥27 with clinical criteria), but the cost-sharing structure excludes the most access-constrained population. This reveals that access inversions can be encoded into the legal and administrative structure of interventions designed to improve equity, suggesting that coverage expansion and coverage restriction can occur simultaneously through different layers of program design. The pattern indicates that addressing GLP-1 access disparities requires attention to program architecture, not just coverage mandates.

+Age 65+ adults show only 9% GLP-1 usage compared to 22% for ages 50-64, directly reflecting Medicare's statutory exclusion of weight-loss drugs. This creates a sharp discontinuity at the Medicare eligibility threshold despite this population having the highest obesity burden and worst health outcomes. The demographic pattern confirms that structural coverage exclusions, not clinical need, determine access.

 The Medicare GLP-1 Bridge program demonstrates that access inversion operates at the federal program design level, not just state-level coverage decisions.

The 56% affordability difficulty rate among current users demonstrates cost barriers operate even after initial access is achieved.

 # GLP-1 long-term persistence remains structurally limited at 14 percent by year two despite year-one improvements
 
 Despite the near-doubling of year-one persistence rates, Prime Therapeutics data shows only 14% of members newly initiating a GLP-1 for obesity without diabetes were persistent at two years (1 in 7). Three-year data from earlier cohorts shows further decline to approximately 8-10%. The striking divergence between year-one persistence (62.7% for semaglutide in 2024) and year-two persistence (14%) suggests that the drivers of short-term adherence improvement—supply access, initial motivation, dose titration support—are fundamentally different from the drivers of long-term dropout. This creates a structural ceiling on long-term adherence under current support infrastructure. The mechanisms that successfully doubled year-one persistence (supply normalization, improved patient management) do not translate to sustained behavior change, suggesting that continuous monitoring, behavioral support, or different care delivery models may be required to address the long-term adherence problem. This persistence ceiling is the specific mechanism by which the population-level mortality signal from GLP-1 therapy gets delayed despite widespread adoption.

+Cost is a major driver of discontinuation: 14% of former GLP-1 users stopped due to cost, matching the 13% who stopped due to side effects. Among current users, 56% report difficulty affording medications, suggesting cost pressure operates throughout the treatment duration, not just at initiation. The 27% of insured users paying full out-of-pocket cost indicates insurance coverage gaps contribute to persistence failures.

 # Never-skilling is mechanistically distinct from deskilling because it affects trainees who lack baseline competency rather than experienced physicians losing existing skills
 
 Oettl et al. explicitly distinguish 'never-skilling' from deskilling as separate mechanisms with different populations and dynamics. Deskilling affects experienced physicians who have baseline competency and lose it through AI reliance. Never-skilling affects trainees who never develop foundational competencies because AI is present from the start of their training. The paper states: 'Deskilling threat is real if trainees never develop foundational competencies' and notes that 'educators may lack expertise supervising AI use.' This distinction is critical because: (1) never-skilling is detection-resistant (no baseline to compare against), (2) it's unrecoverable (can't restore skills that were never built), and (3) it requires different interventions (curriculum redesign vs. retraining). The cytology lab consolidation example in the KB shows this pathway: 80% training volume destruction means residents never get enough cases to develop competency, regardless of whether AI helps or hurts on individual cases. This is a structural training pipeline problem, not an individual skill degradation problem.

This meta-skill deficit only becomes visible when trainees must independently triage cases without AI routing.
