California Becomes Latest State To Try Capping Health Care Spending

California’s Office of Health Care Affordability faces a herculean task in its plan to slow runaway health care spending.
The goal of the agency, established in 2022, is to make care more affordable and accessible while improving health outcomes, especially for the most disadvantaged state residents. That will require a sustained wrestling match with a sprawling, often dysfunctional health system and powerful industry players who have lots of experience fighting one another and the state.
Can the new agency get insurers, hospitals, and medical groups to collaborate on containing costs even as they jockey for position in the state’s $405 billion health care economy? Can the system be transformed so that financial rewards are tied more to providing quality care than to charging, often exorbitantly, for a seemingly limitless number of services and procedures?
The jury is out, and it could be for many years.
California is the ninth state — after Connecticut, Delaware, Massachusetts, Nevada, New Jersey, Oregon, Rhode Island, and Washington — to set annual health spending targets.
Massachusetts, which started annual spending targets in 2013, was the first state to do so. It’s the only one old enough to have a substantial pre-pandemic track record, and its results are mixed: The annual health spending increases were below the target in three of the first five years and dropped beneath the national average. But more recently, health spending has greatly increased.
In 2022, growth in health care expenditures exceeded Massachusetts’ target by a wide margin. The Health Policy Commission, the state agency established to oversee the spending control efforts, warned that “there are many alarming trends which, if unaddressed, will result in a health care system that is unaffordable.”
Neighboring Rhode Island, despite a preexisting policy of limiting hospital price increases, exceeded its overall health care spending growth target in 2019, the year it took effect. In 2020 and 2021, spending was largely skewed by the pandemic. In 2022, the spending increase came in at half the state’s target rate. Connecticut and Delaware, by contrast, both overshot their 2022 targets.
It’s all a work in progress, and California’s agency will, to some extent, be playing it by ear in the face of state policies and demographic realities that require more spending on health care.
And it will inevitably face pushback from the industry as it confronts unreasonably high prices, unnecessary medical treatments, overuse of high-cost care, administrative waste, and the inflationary concentration of a growing number of hospitals in a small number of hands.
“If you’re telling an industry we need to slow down spending growth, you’re telling them we need to slow down your revenue growth,” says Michael Bailit, president of Bailit Health, a Massachusetts-based consulting group, who has consulted for various states, including California. “And maybe that’s going to be heard as ‘we have to restrain your margins.’ These are very difficult conversations.”
Some of California’s most significant health care sectors have voiced disagreement with the fledgling affordability agency, even as they avoid overtly opposing its goals.
In April, when the affordability office was considering an annual per capita spending growth target of 3%, the California Hospital Association sent it a letter saying hospitals “stand ready to work with” the agency. But the proposed number was far too low, the association argued, because it failed to account for California’s aging population, new investments in Medi-Cal, and other cost pressures.
The hospital group suggested a spending increase target averaging 5.3% over five years, 2025-29. That’s slightly higher than the 5.2% average annual increase in per capita health spending over the five years from 2015 to 2020.
Five days after the hospital association sent its letter, the affordability board approved a slightly less aggressive target that starts at 3.5% in 2025 and drops to 3% by 2029. Carmela Coyle, the association’s chief executive, said in a statement that the board’s decision still failed to account for an aging population, the growing need for mental health and addiction treatment, and a labor shortage.
The California Medical Association, which represents the state’s doctors, expressed similar concerns. The new phased-in target, it said, was “less unreasonable” than the original plan, but the group would “continue to advocate against an artificially low spending target that will have real-life negative impacts on patient access and quality of care.”
But let’s give the state some credit here. The mission on which it is embarking is very ambitious, and it’s hard to argue with the motivation behind it: to interject some financial reason and provide relief for millions of Californians who forgo needed medical care or nix other important household expenses to afford it.
Sushmita Morris, a 38-year-old Pasadena resident, was shocked by a bill she received for an outpatient procedure last July at the University of Southern California’s Keck Hospital, following a miscarriage. The procedure lasted all of 30 minutes, Morris says, and when she received a bill from the doctor for slightly over $700, she paid it. But then a bill from the hospital arrived, totaling nearly $9,000, and her share was over $4,600.
Morris called the Keck billing office multiple times asking for an itemization of the charges but got nowhere. “I got a robotic answer, ‘You have a high-deductible plan,’” she says. “But I should still receive a bill within reason for what was done.” She has refused to pay that bill and expects to hear soon from a collection agency.
The road to more affordable health care will be long and chock-full of big challenges and unforeseen events that could alter the landscape and require considerable flexibility.
Some flexibility is built in. For one thing, the state cap on spending increases may not apply to health care institutions, industry segments, or geographic regions that can show their circumstances justify higher spending — for example, older, sicker patients or sharp increases in the cost of labor.
For those that exceed the limit without such justification, the first step will be a performance improvement plan. If that doesn’t work, at some point — yet to be determined — the affordability office can levy financial penalties up to the full amount by which an organization exceeds the target. But that is unlikely to happen until at least 2030, given the time lag of data collection, followed by conversations with those who exceed the target, and potential improvement plans.
In California, officials, consumer advocates, and health care experts say engagement among all the players, informed by robust and institution-specific data on cost trends, will yield greater transparency and, ultimately, accountability.
Richard Kronick, a public health professor at the University of California-San Diego and a member of the affordability board, notes there is scant public data about cost trends at specific health care institutions. However, “we will know that in the future,” he says, “and I think that knowing it and having that information in the public will put some pressure on those organizations.”

What is hyaluronic acid – and is it OK for kids and teens to use this common skincare ingredient?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Earlier this month, Kmart pulled a “hyaluronic acid cleansing balm” from its shelves, after a teen who used the skincare product was hospitalised, reporting eye pain and blurred vision. It’s unclear what ingredient caused this reaction.
In a statement, Kmart said it was removing the product while conducting an investigation. The retailer also said:
We want to assure our customers that our cosmetics are designed to ensure that they comply with both Australian and European requirements on ingredients.
Hyaluronic acid – despite the name – is a gentle ingredient commonly used in skincare products.
But what does hyaluronic acid do to your skin as a skincare ingredient? And is it safe for tweens and teens?
Sabinayro/Shutterstock What is hyaluronic acid?
Hyaluronic acid is a glycosaminoglycan – a sugar-based molecule found naturally in the skin, eyes, joint fluid and connective tissue.
It plays a key role in hydrating the skin and tissues, lubricating our joints and supporting tissue repair.
Beyond cosmetics, hyaluronic acid is used in drug delivery, regenerative medicine, wound repair, and to treat conditions such as atherosclerosis (where the arterial walls harden and narrow) and osteoarthritis (a degenerative joint disease).
It is also a key ingredient in many eye drops and contact lens care solutions.
How is it used in skincare?
While the word “acid” might suggest it is harsh and potentially damaging to the skin, hyaluronic acid is not used in its acidic form in skincare products. It is usually used in its salt form, sodium hyaluronate.
In skincare, active acids such as salicylic acid usually lower the skin’s pH and exfoliate it by breaking the bonds between dead skin cells.
Hyaluronic acid, in contrast, is used to hydrate the skin. It is a humectant, an ingredient that attracts and retains water molecules.
Hyaluronic acid has three qualities that make it suitable for skincare: it’s soluble (can be dissolved in water), biocompatible (meaning it’s not harmful to the body), and biodegradable (naturally breaks down into non-toxic, simpler substances).
It is usually safe and well-tolerated, meaning it has very few side effects.
In skincare products, hyaluronic is used in different forms. Smaller hyaluronic molecules can penetrate deeper into the skin and hydrate the lower levels. In products this is often advertised as “anti-ageing”, because it stimulates the production of collagen (a structural protein in the skin), and helps to improve elasticity and reduce the appearance of fine lines.
Larger hyaluronic acid molecules remain on the skin’s surface and have an immediate hydrating effect, preventing water evaporation from the skin.
Hyaluronic acid helps the skin attract and retain water molecules for hydration. Art_Photo/Shutterstock Any risks?
Hyaluronic acid is generally a safe ingredient, even for sensitive skin. But products advertised as “hyaluronic acid skincare” may contain other ingredients which can cause irritation.
In particular, fragrances, preservatives and surfactants (ingredients that produce foam and help wash away oil and dirt) may be safe for skin but burn or otherwise irritate the eyes.
This is because the cornea and conjuctiva (the thin membrane covering the eye) are much more sensitive than the skin.
How are skincare ingredients regulated?
Unlike medicines and products used for therapeutic reasons, which are regulated by the Therapeutic Goods Administration (TGA), general cosmetic products do not require pre-market safety testing or approval.
Instead, companies need to register their business with the Australian Industrial Chemicals Introduction Scheme and verify that their ingredients are not banned or restricted in Australia.
This creates a potential gap where defective products remain on the market, only to be recalled after adverse reactions occur.
Are these products appropriate for children?
Most scientific research on active ingredients – including hyaluronic acid – has been evaluated in older populations. This leaves a gap in understanding how they affect teen and preteen skin.
Many products are designed for ageing and/or specific skin types, and are largely unnecessary for children and younger people.
In some cases, they can potentially be harmful to their skin. For example, unless prescribed by a dermatologist, it’s advisable for young people to avoid retinoid products (containing retinol or retinal) as they can cause redness, peeling and drying.
Similarly, products with alpha hydroxy acids can cause irritation, itching, redness and may worsen acne in young skin.
So, what should younger people look for?
Preteens and teens should avoid products containing active ingredients such as retinol, vitamin C, alpha- and beta- hydroxy acids, and peptides, as well as those labelled with terms such as anti-ageing, wrinkle-reducing, brightening, or firming.
To keep skin clean and protected, teenagers can use a good cleanser, a simple moisturiser and a broad spectrum SPF 30 or 50 sunscreen.
It’s best to opt for gentle, fragrance-free cleansers and moisturisers suitable for all skin types. Consulting with a pharmacist can provide personalised recommendations based on individual skin needs.

Measles cases are rising—here’s how to protect your family
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
The U.S. is currently experiencing a spike in measles cases across several states. Measles a highly contagious and potentially life-threatening disease caused by a virus. The measles-mumps-rubella (MMR) vaccine prevents measles; unvaccinated people put themselves and everyone around them at risk, including babies who are too young to receive the vaccine.
Read on to learn more about measles: what it is, how to stay protected, and what to do if a measles outbreak happens near you.
What are the symptoms of measles?
Measles symptoms typically begin 10 to 14 days after exposure. The disease starts with a fever followed by a cough, runny nose, and red eyes and then produces a rash of tiny red spots on the face and body. Measles can affect anyone, but is most serious for children under 5, immunocompromised people, and pregnant people, who may give birth prematurely or whose babies may have low birth weight as a result of a measles infection.
Measles isn’t just a rash—the disease can cause serious health problems and even death. About one in five unvaccinated people in the U.S. who get measles will be hospitalized and could suffer from pneumonia, dehydration, or brain swelling.
If you get measles, it can also damage your immune system, making you more vulnerable to other diseases.
How do you catch measles?
Measles spreads through the air when an infected person coughs or sneezes. It’s so contagious that unvaccinated people have a 90 percent chance of becoming infected if exposed.
An infected person can spread measles to others before they have symptoms.
Why are measles outbreaks happening now?
The pandemic caused many children to miss out on routine vaccinations, including the MMR vaccine. Delayed vaccination schedules coincided with declining confidence in vaccine safety and growing resistance to vaccine requirements.
Skepticism about the safety and effectiveness of COVID-19 vaccines has resulted in some people questioning or opposing the MMR vaccine and other routine immunizations.
How do I protect myself and my family from measles?
Getting an MMR vaccine is the best way to prevent getting sick with measles or spreading it to others. The CDC recommends that children receive the MMR vaccine at 12 to 15 months and again at 4 to 6 years, before starting kindergarten.
One dose of the MMR vaccine provides 93 percent protection and two doses provide 97 percent protection against all strains of measles. Because some children are too young to be immunized, it’s important that those around them are vaccinated to protect them.
Is the MMR vaccine safe?
The MMR vaccine has been rigorously tested and monitored over 50 years and determined to be safe. Adverse reactions to the vaccine are extremely rare.
Receiving the MMR vaccine is much safer than contracting measles.
What do I do if there’s a measles outbreak in my community?
Anyone who is not fully vaccinated for measles should be immunized with a measles vaccine as soon as possible. Measles vaccines given within 72 hours after exposure may prevent or reduce the severity of disease.
Children as young as 6 months old can receive the MMR vaccine if they are at risk during an outbreak. If your child isn’t fully vaccinated with two doses of the MMR vaccine—or three doses, if your child received the first dose before their first birthday—talk to your pediatrician.
Unvaccinated people who have been exposed to the virus should stay home from work, school, day care, and other activities for 21 days to avoid spreading the disease.
For more information, talk to your health care provider.

Codependency Isn’t What Most People Think It Is
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Codependency isn’t what most people think it is
In popular parlance, people are often described as “codependent” when they rely on each other to function normally. That’s interdependent mutualism, and while it too can become a problem if a person is deprived of their “other half” and has no idea how to do laundry and does not remember to take their meds, it’s not codependency.
Codependency finds its origins in the treatment and management of alcoholism, and has been expanded to encompass other forms of relationships with dependence on substances and/or self-destructive behaviors—which can be many things, including the non-physical, for example a pattern of irresponsible impulse-spending, or sabotaging one’s own relationship(s).
We’ll use the simplest example, though:
- Person A is (for example) an alcoholic. They have a dependency.
- Person B, married to A, is not an alcoholic. However, their spouse’s dependency affects them greatly, and they do what they can to manage that, and experience tension between wanting to “save” their spouse, and wanting their spouse to be ok, which latter, superficially, often means them having their alcohol.
Person B is thus said to be “codependent”.
The problem with codependency
The problems of codependency are mainly twofold:
- The dependent partner’s dependency is enabled and thus perpetuated by the codependent partner—they might actually have to address their dependency, if it weren’t for their partner keeping them from too great a harm (be it financially, socially, psychologically, medically, whatever)
- The codependent partner is not having a good time of it either. They have the stress of two lives with the resources (e.g. time) of one. They are stressing about something they cannot control, understandably worrying about their loved one, and, worse: every action they might take to “save” their loved one by reducing the substance use, is an action that makes their partner unhappy, and causes conflict too.
Note: codependency is often a thing in romantic relationships, but it can appear in other relationships too, e.g. parent-child, or even between friends.
See also: Development and validation of a revised measure of codependency
How to deal with this
If you find yourself in a codependent position, or are advising someone who is, there are some key things that can help:
- Be a nurturer, not a rescuer. It is natural to want to “rescue” someone we care about, but there are some things we cannot do for them. Instead, we must look for ways to build their strength so that they can take the steps that only they can take to fix the problem.
- Establish boundaries. Practise saying “no”, and also be clear over what things you can and cannot control—and let go of the latter. Communicate this, though. An “I’m not the boss of you” angle can prompt a lot of people to take more personal responsibility.
- Schedule time for yourself. You might take some ideas from our previous tangentially-related article:

How Often Do You Eat Fries?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
“Fries are not a health food” is not breaking news, but how often can you get away with them before it starts impacting health outcomes?
Researchers (Dr. Seyed Mousavi et al.) investigated the effects of fries, various kinds of non-fried potatoes, and white vs whole grains, on diabetes risk.
This was done over the course of three US cohort studies involving a total of a total of 205,107 participants, mostly women, whose diet and health outcomes were followed for 4 decades. Of these participants, 22,299 developed type 2 diabetes.
Here’s what they found:
❝After adjustment for updated body mass index and other diabetes related risk factors, higher intakes of total potatoes and French fries were associated with increased risk of T2D.
For every increment of three servings weekly of total potato, the rate for T2D increased by 5% (hazard ratio 1.05, 95% confidence interval (CI) 1.02 to 1.08) and for every increment of three servings weekly of French fries the rate increased by 20% (1.20, 1.12 to 1.28). Intake of combined baked, boiled, or mashed potatoes was not significantly associated with T2D risk (pooled hazard ratio 1.01, 95% CI 0.98 to 1.05).
In substitution analyses, replacing three servings weekly of potatoes with whole grains was estimated to lower T2D rates by 8% (95% CI 5% to 11%) for total potatoes, 4% (1% to 8%) for baked, boiled, or mashed potatoes, and 19% (14% to 25%) for French fries. In contrast, replacing total potatoes or baked, boiled, or mashed potatoes with white rice was associated with an increased risk of T2D.
In a meta-analysis of 13 cohorts (587 081 participants and 43 471 diagnoses of T2D), the pooled hazard ratio for risk of T2D with each increment of three servings weekly of total potato was 1.03 (95% CI 1.02 to 1.05) and of fried potatoes was 1.16 (1.09 to 1.23). In substitution meta-analyses, replacing three servings weekly of total, non-fried, and fried potatoes with whole grains was estimated to lower the risk of T2D by 7% (95% CI 5% to 9%), 5% (3% to 7%), and 17% (12% to 22%), respectively.❞
That’s a lot of numbers, so let’s break it down, translate it from sciencese, and look at some of the key points.
In order, we have, for the emprical data:
- Every extra three servings of total potatoes per week increased risk by 5%
- Every extra three servings of French fries per week increased risk by 20%
- Baked, boiled, or mashed potatoes gave no significant change in risk
- Replacing three weekly servings of total potatoes with whole grains lowered risk by 8%
- Replacing baked, boiled, or mashed potatoes with whole grains lowered risk by 4%
- Replacing French fries with whole grains lowered risk by 19%
- Replacing total potatoes or baked, boiled, or mashed potatoes with white rice increased risk by 15%*
And now for the meta-analysis** numbers:
- Every extra three servings of total potatoes per week increased risk by 3%
- Every extra three servings of fried potatoes per week increased risk by 16%
- Replacing total potatoes with whole grains lowered risk by 7%
- Replacing non-fried potatoes with whole grains lowered risk by 5%
- Replacing fried potatoes with whole grains lowered risk by 17%
*This figure wasn’t in the abstract we quoted above, but we found it in the full substitutions table lower down in the paper, where it’s expressed as a Hazard Ratio of 1.15, which equates to a 15% increase in risk.
**A meta-analysis can be thought of as an “imaginary experiment” performed by collated existing data from other studies, running it through statistical models, and seeing what comes out. As you can see, the resultant numbers are slightly different, but the associations remain the same (i.e. the same additions/substitutions still give approximately the same relative increase/decrease in risk), which means the meta-analysis also supports the conclusions drawn from the empirical data.
On which note, the full paper itself can be found here: Total and specific potato intake and risk of type 2 diabetes: results from three US cohort studies and a substitution meta-analysis of prospective cohorts
That’s a lot of information; what’s most important?
In few words:
- Whole grains are the best
- Non-fried potatoes are ok
- White grains are bad
- Fried potatoes are the worst
Thus, substituting between those four categories will yield changes in risk proportional to how far apart they are from each other on that list.
Furthermore, to answer the question posed in our introduction today (how often can one eat fries before it starts impacting health outcomes), the honest answer is: never, technically.
See for example: Is Fast Food Really All That Bad? ← we realize that fries do not necessarily have to be fast food, but they share the nutritional profile being examined there.
And while “one bad meal” will not impact long-term health, it will have an immediate negative impact on short-term health, due to its gut-disrupting activity. If it really was just a one-off meal, an otherwise healthy gut will bounce back just fine, but it’s another argument for the case of “the negative health effects do start immediately”.
However, the dose does make the poison, and in this case, increments of 3 portions per week increased risk by 20%. We can say, therefore, that each portion per week increases the risk by 6.6%, and this risk is cumulative.
On which note: what is a portion?
- A portion is not: “however much you eat at once”
- A portion is: “a 4–6 oz serving”
So, if you have twice that at a sitting, that’s two portions. Thrice that at a sitting, and that’s the weekly 3 portions that increase the risk by 20%, already, in one day, and if you have more in the rest of the week, it will continue to add to the risk cumulatively.
If you’d like to dial down the portion sizes while simultaneously enjoying what you eat more, there are two useful approaches you might want to consider (you can do both if you want; there’s no conflict between them, and in fact, they can go quite well together):

What is muscle memory and can I improve mine?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Whether it’s riding a bike or knitting a sweater, there are some tasks you do without thinking.
These are commonly associated with “muscle memory”, the idea your body can remember how to perform complex tasks and, over time, learn to do them automatically.
But do your muscles actually have a memory? And what role does your brain play?
Let’s unpack the science.
skynesher/Getty What is ‘muscle memory’?
In popular culture, we usually associate “muscle memory” with tasks we do, or skills we learn, without much conscious thought. This could include riding a bike, playing a musical instrument or even tying your shoelaces.
However, cognitive scientists call this type of memory “procedural memory” rather than “muscle memory”. And while it doesn’t always feel like it, procedural memory involves our brain as well as our muscles.
The term “muscle memory” may also be used in a more literal sense to describe how muscles seem to get stronger or bigger if they have been trained before. Research supports this idea, suggesting prior training can speed up muscle growth. It may do this by changing how muscle cells function or are structured. However, scientists still don’t know exactly how this all works. In any case, it seems these changes do not allow muscles to “store” memories or information in the same way as the brain.
How does procedural memory work?
Scientists describe procedural memory as a kind of “non-declarative memory”, meaning it’s memory based on actions, rather than words. This means it can be difficult to share skills you might’ve learnt through procedural memory.
For example, imagine you’re teaching a child to ride a bike. If you hop on the bike yourself, it’s easy to perform all the correct steps (holding the handlebars, mounting the bike, pushing the pedals) at the right times. But it’s much harder to describe that process to another person, especially if you only use words.
Research suggests repetition is the best and fastest way to improve your procedural memory. When we learn a new skill, it initially takes a lot of effort. This is because you need to actively control every action to make sure you’re doing things in the right way and order.
Over time, these skills can become so automatic you barely think while doing them. For example, you might drive home without remembering which route you took. That’s because you’re performing a series of actions you’ve done hundreds of times before.
Maintaining your procedural memory requires multiple parts of your brain to work together. This is because we use different neural processes as we shift from actively learning a skill to acting more automatically.
When you learn something new, you’re largely using the pre-frontal and fronto-parietal regions of the brain. These are associated with attention, memory and deliberate, effortful thinking.
When you start repeating and practising a skill, you instead rely on sensorimotor circuits. These process the sensory information you receive from the outside world, and help your brain determine the best physical response. In this way, these circuits allow you to do complex tasks with less conscious effort.
What’s the impact of conditions such as dementia?
What’s fascinating about procedural memory is it’s largely unaffected by cognitive decline.
For people with dementia or other kinds of cognitive impairment, the hardest tasks are generally those that require conscious effort. However, they often retain more automatic skills that they’ve developed over a lifetime. This is why you may meet people with dementia who can still knit or dance a tango, despite having trouble remembering their loved ones’ names.
Research suggests music taps into procedural memory in an especially powerful way. One Canadian study found people with Alzheimer’s dementia, an irreversible brain condition which affects memory, cognition and behaviour, recognised words better when they were sung as opposed to spoken.
Procedural memory may also help people with cognitive conditions learn new skills, as well as retain old ones. In one Australian study, researchers wanted to know if a person with severe Alzheimer’s dementia could learn a new song. They found that a 91-year-old woman with severe Alzheimer’s, who’d never been a musician, was able to learn a brand-new song. While she couldn’t remember the words during a memory test, she could sing the song again two weeks later.
Can I improve my procedural memory?
Unfortunately, there’s no quick and easy way to strengthen your procedural memory.
To begin, you have to push through the initial phase of learning a new skill, which often requires significant effort and attention. This is where practice comes in. Practising a new skill will help your brain depend less on its attention-focused frontal regions, and rely more on those responsible for motor functions.
To make your practice as effective as possible, it may be worth spacing it out over multiple sessions. This forces you to deliberately bring a memory back to mind and actively reconstruct it, even after you’ve stopped thinking about it. As a result, you’ll become better at forming and retaining long-term memories. Sleeping after each practice session may also help. Research suggests this is because sleep helps you remember and retain new skills.
While improving procedural memory takes time and effort, it’s well worth it. Any new skills you learn will enrich your life. And even if your cognitive health declines, the skills you practice over a lifetime can keep you connected to the people and memories you value.
