Introduction

The EQ-5D-5L is a short, standardized way to describe health-related quality of life for today. It does two jobs at once. The descriptive system records five parts of health, and the EQ visual analogue scale, usually shortened to EQ VAS, records your own overall health rating from 0 to 100. That combination matters because the five answers show where problems sit, while the EQ VAS shows how your health feels overall.

This page keeps those parts separate on purpose. You answer one question for each EQ-5D-5L dimension, set one EQ VAS value, and then get a five-digit health state such as 22324, an active utility reference, a comparison utility from the other supported tariff, and a report that shows which dimensions are carrying most of the burden. The result is useful for repeat check-ins, rehabilitation follow-up, symptom review, and structured quality-of-life notes where a single headline number would miss too much.

The core instrument result is still the health state plus the EQ VAS. The overview cards, burden map, alignment chart, priority domain, practical notes, and export bundle are page-level helpers built around that core. They can make the result easier to discuss, but they are not new official EQ-5D scores.

Timing is important. The EQ-5D-5L asks about health today, not about the last month and not about your usual average. A check-in taken after a calm morning and a check-in taken after a painful or exhausting day can describe different states even for the same person. If you want to compare runs over time, keep the context as similar as you reasonably can.

Scoring runs in the browser, and the page can keep the five responses, the EQ VAS value, and the selected value set in the URL so the same report can be reopened later. That is convenient for follow-up, but it also means shared links and downloaded files can preserve sensitive health information outside the page. The page describes health status; it does not diagnose the reason for that status.

Technical Details

The EQ-5D-5L descriptive system has five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has five levels running from no problems to severe or extreme difficulty. Once all five answers are complete, they become a five-digit code with 55, or 3,125, possible health states. The EQ VAS then adds a separate self-rating anchored by the best and worst health you can imagine.

Utility = 1 - sum of the selected dimension decrements under the active value set Alignment gap in points = EQ VAS - ( active utility × 100 )

The official building blocks are the descriptive system and EQ VAS. The charts, badges, ranking labels, and export formats on this page are interpretation aids built around those two parts.
Digit Dimension What higher levels mean
1 Mobility More trouble walking, transferring, and getting around.
2 Self-care More trouble washing, dressing, or managing basic personal care.
3 Usual activities More trouble with work, study, household, family, or leisure roles.
4 Pain / discomfort More intense physical pain or bodily discomfort.
5 Anxiety / depression More intense worry, low mood, or emotional distress.

Comparison value-set row Yes, as a reference Only the active highlight changes

This page supports two published EQ-5D-5L value sets: United States 2019 and England 2018. Both convert the same five-digit state into a utility score, but they do not attach the same weight to the same problems. That is why one health state can return two valid utility references while the EQ VAS stays unchanged. The page shows both utilities together and lets you choose which one is active for the burden map, summary line, follow-up notes, and answer-row decrement column.

Negative utility values are possible under these tariffs for very severe states. That is not a calculation bug. It means the valuation study placed that health state below 0 on the utility scale, sometimes described as worse than dead in preference-based health economics. The EQ VAS can still be above 0 in the same situation because it reflects the person's own rating, not a population preference value.

All calculations on this page are client-side. There is no separate server scoring step for the health state, utility comparison, charts, or answer payload. Privacy is therefore shaped less by the calculation itself and more by whether you keep shareable URLs, clipboard copies, CSV or DOCX exports, chart PNG files, or export files after the report is built.

Everyday Use & Decision Guide

Use the page as a same-day check-in, not as a memory exercise. If you answer from a typical month, the health state gets blurred and repeat comparisons become less trustworthy. A better habit is to answer at roughly the same point in the day, especially if pain, fatigue, medication timing, or activity level can swing your condition.

Read the finished report in a fixed order. Start with the five-digit state, because that is the clearest record of which dimensions changed. Then read the active utility and the burden map to see how the chosen tariff weights that state. After that, look at the EQ VAS and the alignment chart to decide whether your own overall rating is close to the published utility or telling a somewhat different story.

The value-set switch is mainly for reporting context, not for personal trend detection. If you want to compare one visit with the next, keep the same tariff active. If you switch from US 2019 to England 2018 in the middle of a series, some of the change you notice may come from the tariff rather than from your health.

The answer-row table is often more useful than the utility alone. It preserves the selected statement, the level, the active decrement, and the profile role for each dimension. That makes follow-up more concrete. Instead of saying only that utility fell, you can point to a change in mobility, a new self-care problem, or a sharper rise in pain/discomfort.

Exports are helpful when you need a record, but they also create new privacy obligations. This page can save answer rows as CSV or DOCX, chart images and chart data, the value-set comparison as CSV, and a structured answer record summary. Use those files when they solve a real follow-up need, and handle them like any other personal health document.

Step-by-Step Guide

  1. Begin the assessment and answer all five dimensions for how health is today.
  2. Move to the EQ VAS step and set the 0 to 100 slider to match your overall health rating for the same day.
  3. Check the summary first: the five-digit state, the active utility, the EQ VAS, and the balance or alignment badges.
  4. Use the overview cards and the dimension table to see which domain is carrying the biggest decrement and which function area is weakest.
  5. Read the EQ Domain Burden Map to compare the active decrement attached to each chosen level.
  6. Read the Utility vs EQ VAS Alignment Map and the value-set reference rows to compare US 2019, England 2018, and EQ VAS on one frame.
  7. Export CSV, DOCX, or PNG only if you need to save or share the result for follow-up.

Interpreting Results

A five-digit state tells you where the burden sits. A utility tells you how a published value set weights that state. The EQ VAS tells you how health feels overall to the person answering. Those are related signals, but they are not interchangeable, and this page works best when you keep them in that order.

A state of 11111 means no reported problems across all five descriptive dimensions. That can still sit beside an EQ VAS that is well below 100. Someone may rate overall health lower because of issues not well captured by the five dimensions, because the day feels worse than the profile suggests, or because the person is using the EQ VAS more broadly than the utility scale does.

The reverse can happen too. A person may have several dimensions above level 1, yet still give a stronger EQ VAS than the active utility would suggest. On this page, that appears as a positive alignment gap, often labeled as EQ VAS above utility. It is not a mistake to be corrected. It means the descriptive profile and the overall self-rating are not landing in the same place.

When you switch from US 2019 to England 2018, the health state does not move. Only the published weights move. That matters because the same state can look more or less severe depending on the valuation set. The burden map and the active decrement column make that visible by showing which dimension takes the largest weight under the selected tariff.

Page-level labels such as overall level, top burden, lowest-function area, and function-led or symptom-led balance are best read as quick orientation tools. They help you scan a complicated result, but they do not replace the actual answers. If a follow-up conversation matters, go back to the chosen statements and the five-digit state.

The most useful interpretation questions are concrete. Which dimension changed? Did the change happen in function, pain, or mood? Did the active utility move because the health state changed or because the tariff changed? Does the EQ VAS agree with that direction? Those questions are usually more informative than asking whether one number is simply good or bad.

Worked Examples

A clean baseline

State 11111 gives a utility of 1.000 under both supported value sets because no dimension is above level 1. If the EQ VAS is also high, the result works well as a baseline for later comparison. If the EQ VAS is noticeably lower, the state is still valid, but the difference tells you that overall health feels worse than the five dimensions alone suggest.

Mostly symptom burden with a modest tariff gap

State 11223 means no problems in mobility and self-care, slight problems in usual activities, slight pain/discomfort, and moderate anxiety/depression. On this page that state scores 0.749 with US 2019 and 0.783 with England 2018. If EQ VAS is 76, the self-rating sits close to both utilities, and the report will usually read as a symptom-led profile rather than a broad function loss.

The same day can feel better than the tariff looks

State 22324 produces a utility of 0.355 with US 2019 and 0.481 with England 2018. If the same person gives an EQ VAS of 65, the alignment gap is clearly positive under either tariff. The result does not mean one number is wrong. It means the person rates overall health better than the population-preference weights for that state would imply.

A very severe state can go below zero

State 55555 produces a negative utility in both supported tariffs on this page. That reflects the published valuation studies, not invalid input. A person can still give a positive EQ VAS, and the report should then be read as a severe descriptive state plus a separate self-rating rather than as a broken score.

FAQ:

Does switching the value set change my five-digit health state?

No. The five answers and the EQ VAS stay the same. Only the active utility, burden map, active decrement column, and alignment summary change.

Why can the utility be negative?

Because some very severe EQ-5D-5L states are valued below 0 in published population preference studies. On this scale, that means the state is treated as worse than dead, not that the result is invalid.

Does EQ VAS need to match the utility?

No. EQ VAS is the person's own overall health rating. Utility is a published value-set score for the descriptive state. A gap between them is often informative.

Are my answers sent to a server for scoring?

The calculation on this page runs in the browser. The bigger privacy risk comes from shared URLs, copied text, and exported files that preserve the result afterward.

Can this page diagnose a condition or explain why a dimension got worse?

No. It describes health status and compares published utility references. Diagnosis and treatment decisions still depend on clinical assessment and the underlying cause of the reported problems.
