Felt rather unfortunately information light to me — lots of evidence that standards for adult ADHD are lacking, but not a lot of investigation into what those standards should look like.
Reading through the article, it definitely highlighted concerns I had about my process: lack of available providers (to the point that many wouldn't even accept a call from a new patient), essentially forced to use online services, relatively short discussions before treatment, and ultimately being prescribed stimulants.
Overall, I'm glad I started this process. I definitely feel better on the medication, to the point where I'm able to effectively track my daily tasking, keep cohesive notes, drastically reduce my unintended verbal interruptions of others, and churn work out without context switching so often. I obviously can work without the medication, but it's absolutely a night and day difference to me. Ultimately, I just hope that the progression of the adult ADHD diagnosis and discovery continues to mature, and online services aren't completely cut off from the space.
That said, the answer to "what is the solution" is that it takes time to figure out what the best treatment plans are and feedback success and failure into diagnostics. It is a process of never-ending improvement. For example depression was known to Hippocrates and despite that multiple thousands of years of history we still don't have a 100% success rate diagnostics and treatment for it. Adult ADHD is only about 10 years old. Odds are by the time it grows up the current symptoms will lessen. But in the meantime, people seeking treatment for it should be aware that they are part of an ongoing experiment, i.e. they are in the Wild West.
Takeda (who manufacture Elvanse in Europe) are being very coy about what "manufacturing issues" means. Their latest estimate for a return to full production is Q2 2024, but it's slipped before.
/r/adhduk is quite good at tracking updates around shortages.
