Strictly speaking, these aren't truly injuries but the result of old age taking its toll on a colonist's body. Chronic diseases are ''significantly'' more likely to occur past a pawn's life expectancy. All occurring ages are based on humans, and will obviously be different with animals dependent on life expectancy. Humans stop getting birthdays past the age of 99.

Humanoids, animals, and mechanoids sustain injuries from sources including melee weapons, weapons fire, explosions, ceiling collapses, and fire. Each source of damage comes with a specific Damage Type. Colonists, visitors, and prisoners can be operated upon and may suffer an injury from a surgical mistake. Each kind of injury has a value of pain, a description for its scar, and flavor text for being mended by medicine. A colonist in shock from extreme pain or incapacitated due to loss of movement becomes ' downed'. Doctors will automatically rescue downed colonists.

Injury types

Different weapons cause different types of injuries. For example, a mace will crush, a longsword will cut, and fire will burn. The type of injury impacts the amount of pain it causes, the rate of bleeding, and the chance it gets infected.

Pain

Injuries cause pain to a colonist, and excessive pain can cause a pawn to be downed from pain shock.

Most pawns go into pain shock once their pain exceeds 80% except for wimps who are downed at 20% pain.

Recovering from injuries

Injured colonists will recover from their wounds over time. Every couple of minutes in game, a random injury will be healed by a small amount. This healing reduces the severity of the injury, and when the severity of the injury reaches zero the injury is fully healed.

Every 600 ticks heal rate × 0.01

points of damage are healed from a randomly selected (non-permanent) wound.

The exact heal rate is determined by adding up three factors:

  • Default healing rate: All pawns have a base heal rate of 8
  • Is the pawn lying down or in a bed?: +4 for resting on a sleeping spot or the ground, +8 for resting on a bed / bedroll, and +14 for resting on a hospital bed
  • Is the wound tended?: +4 for a 0% quality tend and +0.08 per point of tend quality, up to +12 at 100% tend quality

To put this in perspective, consider a colonist who has taken 20hp of damage to various body parts. The colonist heals heal rate × 0.01

points of damage every 600 ticks, so they'll need 20 ÷ (heal rate × 0.01)
ticks to fully recover.

To give a few examples:

  • Do nothing: With no tending or rest, they get the base heal rate of 8, so it'll take 150,000 ticks (2 and a half in-game days) to heal
  • Basic tend and resting: With a 40% tend quality (+7.2) and rest in a non-hospital bed (+8), they have a heal rate of 8 + 7.2 + 8 = 23.2, so it'll take 51,724 ticks to heal (around 21 hours in game)
  • Best quality care: With 100% tend quality (+12) and rest in a hospital bed (+14), they have a heal rate of 8 + 12 + 14 = 34, so it'll take 35,294 ticks to heal (around 14 hours in game)

Note that immunity gain speed has no influence on the recovery rate from injuries -- it only affects recovery from disease

Non-Local Injuries

Some injuries are not applied to specific body parts, but listed as affecting the entire body of a pawn. They are as follows:

Starvation

When a pawn's food meter reaches 0% they will begin to suffer from malnutrition, shown on the Health tab. When a colonist is starving they will prioritize eating over other activities, including firefighting and doctoring.

  • Malnutrition starts at 0%; upon reaching 100%, the pawn will die.
  • Malnutrition (trivial): consciousness -5%, 150% hunger rate
  • Malnutrition (minor): consciousness -10%, 160% hunger rate
  • Malnutrition (moderate): consciousness -20%, 160% hunger rate
  • Malnutrition (severe): consciousness -30%, 160% hunger rate
  • Malnutrition (extreme): consciousness max 10%
  • Malnutrition (100% severity): death

Blood Loss

Blood loss occurs when a pawn has untreated bleeding wounds. Bleeding wounds are identified on the Health tab by a blood icon and a tooltip shows the bleeding rate. Total blood loss is listed under Whole Body and its tooltip shows the total blood loss. Overall bleeding rate is shown at the bottom.

Once all bleeding wounds are healed the pawn will start recovering from blood loss. It takes up to 4 days to fully recover.

  • Blood loss starts at 0%; upon reaching 100%, the pawn will die.
  • Blood loss (minor): consciousness -10%
  • Blood loss (moderate): consciousness -20%
  • Blood loss (severe): consciousness -40%
  • Blood loss (extreme): consciousness max 10%
  • Blood loss (100% severity): death

Heatstroke

Heat stroke occurs when a pawn has prolonged exposure to temperatures well above their maximum comfortable temperature.

  • Heatstroke (initial): consciousness -5%
  • Heatstroke (minor): consciousness -10%, moving -10%
  • Heatstroke (serious): consciousness -20%, moving -30%, pain +15%
  • Heatstroke (extreme): consciousness max 10%, pain +30%
  • Heatstroke (100% severity): death

Hypothermia

Hypothermia occurs when a pawn has prolonged exposure to temperatures well below their minimum comfortable temperature.

  • Hypothermia (shivering): consciousness -5%, manipulation -8%
  • Hypothermia (minor): consciousness -10%, manipulation -20%, moving -10%
  • Hypothermia (serious): consciousness -20%, manipulation -50%, moving -30%, pain +15%
  • Hypothermia (extreme): consciousness max 10%, pain +30%
  • Hypothermia (100% severity): death


Heart Attack

Heart Attacks can randomly occur on any pawn/animal at any time, but they become more frequent as they pass half of their life expectancy (e.g. 40 years in Humans), triggered by Birthday event. There must be more than 2 colonists on your colony for this to occur.

The average interval between heart attacks is curved as follows (in days).

0-50% of LE: 99,999,999 - 99,999,999
50-60% of LE: 99,999,999 - 2,500
60-100% of LE: 2,500 - 300

Examples of intervals and chances:
55% of Life Expectancy (e.g. 44 in humans): 50,001,249.5 days (approx. 0.00000002% per day)
80% of Life Expectancy (e.g. 64 in humans): 1,400 days (approx. 0.000714% per day)

Stages

A heart attack has 3 stages.

Painful: 0 - 59% severity

  • Consciousness x50%
  • Pain +40%

Debilitating: 60 - 99% severity

  • Consciousness max 10%
  • Pain +60%

Fatal: 100% severity

  • Death

Progression

Heart attacks always start at 40% severity. Every 5,000 ticks (1.39 mins) the heart attack severity will randomly change by a value between -40% to +60%. This means that it is possible for a heart attack to treat itself on its own, but usually the heart attack progresses to fatal severity.

Treatment

Like injuries, medicine can be used to treat a heart attack.

Doctors treating heart attacks will administer treatments rapidly, consuming medicine in the process. Each treatment has a chance to succeed, reducing the heart attack severity by 30%. Successfully reducing severity below 0 will completely treat the heart attack.

The maximum chance a particular treatment can succeed is 65%.

Scarring

Scars are permanent markers of injuries. They permanently lower the maximum health of the scarred body part, making it easier to damage the affected body part in the future.

Scars are permanent markers of injuries. They permanently lower the maximum health of the scarred body part, making it easier to damage the affected body part in the future. They also cause a character a small amount of pain, even if the relevant body part is fully healed. Pain from scars results in a permanent mood penalty for non-masochistic characters. For a colonist with the Masochist trait, scar pain will provide a continual mood bonus instead of penalty.

Sometimes colonists are generated with minor scars and old gunshots already in place. Some body parts also scar instantly upon injury.

It is possible to remove the pain from some scars by surgically implanting artificial replacements. Artificial body parts will never scar.

Scars can be treated by luciferium, however the cost of using it usually outweighs the benefit, unless used on numerous scars, or a permanent brain injury.

Another way to work around scar pain is to implement a Painstopper, preventing all ongoing pain. The downside to this, however, is that should the pawn with an installed Painstopper take serious damage - they won't go down until they either lose a leg (or have it heavily injured), or die. Therefore, you should be extra watchful of their health as to decide whether to withdraw them from a controllable scenario (i.e. combat), as to prevent them from losing their life.

Trauma Savant

Being shot in the brain can cause the trauma savant condition.

A pawn may become a trauma savant upon taking and surviving an injury to the Brain. Certain capabilities will rise and some will fall.

Trauma Savant currently removes all ability to socialise and opinions of others, capability of Talking and Hearing (both capped at 0%), but increases Manipulation by 50%, and restores full brain functioning (meaning consciousness and other functions will be normal) - this is great for doctors and general workers, but it'll make affected wardens or traders a write-off in that aspect.

There is a 12% chance of any pawn becoming a trauma savant upon receiving brain damage. It does not have to be a humanlike, and can sometimes be seen applied on animals.


Trivia

Brain injuries in Rimworld cause large amounts of pain (20% or higher for a 5 hp wound), often rendering a pawn permanently comatose in extreme cases, this being due to pain stacking with the reduced part efficiency. However, in real life the human brain has no pain receptors. This is due to how if anything manages to get into the brain and damage it, it will already have caused intense pain from having to penetrate the skull, and the person is likely going to be fatally wounded regardless of how they react. Headaches are often caused by receptors triggering elsewhere in the head or neck, not by receptors in the brain
