The Social Determinants of Health and Perioperative Outcomes by Surgical Specialty: A Scoping Review
This scoping review of 167 articles synthesizes existing evidence on the relationship between social determinants of health and perioperative outcomes, revealing strong links between socioeconomic status and mortality as well as insurance status and hospital utilization, while highlighting significant gaps in research regarding language, health literacy, and other demographic factors.

Imagine you are about to take a very important, high-stakes journey. You have a map (your medical history), a vehicle (your body), and a pilot (the surgeon and anesthesiologist). Usually, when we check if you're ready for the trip, we look at the engine and the fuel tank. We ask: "Is your heart strong? Is your blood pressure okay?"
But this paper asks a different question: "What about the road you're driving on, and who is paying for the gas?"
The authors, a team from the University of Wisconsin–Madison, conducted a massive "scoping review." Think of this as a giant treasure hunt. Instead of looking for gold, they looked for 167 different research papers that tried to connect Social Determinants of Health (SDOH) with surgery outcomes.
Here is the simple breakdown of what they found, using some everyday analogies:
1. The "Road Conditions" (Social Determinants)
The paper defines SDOH as the conditions where people are born, grow, work, and live. In our travel analogy, these are the potholes, toll booths, and weather conditions you face before you even get in the car. The team looked at specific road conditions:
- Money (Socioeconomic Status): How much cash you have.
- The Ticket (Insurance): Whether you have a valid ticket to ride.
- The Map (Access to Care): How far you have to drive to get to a good hospital.
- The Language (Language/Health Literacy): Whether you can read the signs or understand the pilot's instructions.
- Who You Are (Race and Sex): The identity of the traveler.
2. The "Destination" (Surgery Outcomes)
They were looking at what happens after the surgery. Did the patient survive? Did they stay in the hospital too long? Did they have to come back (readmission)? Did they have a heart attack or stroke?
3. What the Treasure Hunt Revealed
The "Money" Connection (Strongest Link)
The clearest finding was about Socioeconomic Status (money). It's like a heavy backpack. The more "backpack" (financial struggle) a patient carries, the higher the risk they have of dying after surgery. The study found strong evidence that if you have less money, you are more likely to have a bad outcome.
The "Ticket" Connection (Insurance)
Having the right insurance was like having a VIP pass.
- If you had public insurance (or no insurance), you were much more likely to stay in the hospital longer and more likely to be readmitted later.
- It's as if the "ticket" you hold determines how smoothly your journey goes. The paper suggests insurance status is a huge predictor of how long you stay in the hospital and whether you have to come back.
The "Identity" Connection (Race and Sex)
This part was foggy, like driving through a thick mist.
- Race: The team found mixed results. Some studies said minority groups had worse outcomes; others said there was no difference at all. The authors suggest this might be because the "maps" (data) we use to track race are often incomplete or inaccurate. They also note that race is a social construct, and the real issues might actually be the "road conditions" (money, access) that often go hand-in-hand with race, rather than race itself.
- Sex: Similarly, the results were all over the place. Some studies said men did worse; others said women did worse; many said there was no difference. The paper concludes we just don't have a clear picture yet.
The "Missing Signs" (Language and Health Literacy)
This was the biggest gap in the map. The team found almost no research on how language barriers or health literacy (how well you understand medical instructions) affect surgery.
- Imagine trying to fly a plane where the pilot speaks a language you don't understand, and the safety manual is written in a language you can't read. The paper found very few studies looking at this specific danger zone.
4. The "Pilot's Checklist" (Anesthesia)
The authors noticed something interesting about the "pilots" (anesthesiologists). In many of the studies they reviewed, the researchers didn't even check what kind of anesthesia was used. It's like a car review that ignores whether the car has a V8 engine or a hybrid motor.
- Only a tiny fraction of the studies adjusted for the type of anesthesia. This means we might be missing a key piece of the puzzle about why some patients do better than others.
The Bottom Line
The paper concludes that while we know money and insurance play a huge role in how well a surgery goes, we are still guessing about race, sex, and language.
The authors argue that before we send a patient to the operating room, we shouldn't just check their heart and lungs. We need to look at their "road conditions." If we start screening for these social factors (like asking about insurance, language, or financial stress) in the pre-surgery clinic, we might be able to fix the "potholes" before the journey even begins, ensuring a safer trip for everyone, regardless of who they are or how much money they have.
In short: The paper says, "We found that money and insurance matter a lot for surgery success. We found that race and sex are complicated and unclear. We found that we are almost totally ignoring language and reading skills. We need to start looking at the whole picture, not just the medical chart."
