Editing Doctoring

{{Rewrite|reason = Cleanup, fact check, [[Template:Verified|verification]]}}
{{TOCright}}

'''Doctoring''' is a type of work assigned to colonists from the [[Work|Work menu]]. The [[Medical]] skill is the primary determinant for success. Colonists [[incapable]] of Caring will never perform doctor work.

Doctor work assigns pawns to the following jobs: tending to patients, tending to self (if enabled), feeding patients, performing surgical operations, rescuing downed pawns or downed tamed animals, tending to and operating on animals, feeding ill animals, and cheering up patients. 

How well a colonist performs in Doctoring mainly depends on their medical [[skill]], the quality of [[medicine]] used, and the cleanliness of the [[room]] in which they are operating. The doctor's physical condition plays an important role, too.

Doctors can heal other colonists, guests, prisoners or animals and will prioritize life-threatening wounds and illnesses before tending minor conditions.

Doctors can "self-tend" at 70% effectiveness to treat their own wounds or illnesses. Disabled by default, the self-tend option can be enabled in a pawn's Health-overview.

== Skill ==
The Medicine skill is the center skill of doctoring in RimWorld. It directly multiplies the treatment quality as well as surgery success chance and healing speed before other factors are taken in. All values in this table take post-processing into account where necessary.

{{Medicine Experience Gain Table|{{STDT| c_10 text-center}} }}

== Medicines ==
Medicine is used to improve the results of doctoring, therefore improving recovery from injuries and disease, and also allowing the performing of surgery. Another perk to using medicine is that medicine is typically able to heal multiple low severity injuries (up to max of 20 damage worth of severity), which is something that 'dry-bandaging' can't do.

There are currently three types of medicine in RimWorld: the organic [[herbal medicine]], the bog standard [[medicine]], and the coveted [[glitterworld medicine]] - in order from least potent to most potent.

It is possible to change the default healthcare given to pawns. Defaults to best meds for colonists and herbal meds for everybody else.{{Check Tag|Detail|How do you do it, what options are available etc. Doesn't necessarily have to be here, but should at least link to the right place.}}

=== Treatment options ===
Five treatment options are available; none at all, doctor care, herbal medicine or worse, regular medicine or worse, or best quality medical care. 

For prisoners and guests the default is herbal medicine; colonists default to best care available.

In the early game, however, it is ideal to set the medical policy so that all pawns on the map only get basic doctor treatment. This allows precious medicine to be stockpiled for emergencies an operations rather than wasted on minor injuries.

=== No medical care ===
Somewhat straightforward, this option prevents pawns from receiving any sort of medical care. This will leave them to succumb to their wounds, or die of diseases without anyone to treat them.

As doctor care does not require any medicine, this option is not recommended unless your intent is to let the pawn die.

=== Doctor care, but no medicine ===
[[File:Doctor care but no medicine.png|left]]
Sometimes when supplies are short, or you need to save your stocks of medicine for better purposes, doctors will attempt to improvise a treatment. '''Note''' that it is not possible to do surgeries without medicine, and treatment is much slower than with any form of medicine, especially being unable to treat multiple wounds in a single treatment. Expect many infections from the poor treatment quality.

=== Herbal medicine ===
[[{{Q|Herbal medicine|Image}}|left]]
Herbal medicine is an organic medicine which can be grown from [[healroot]], or purchased from tribal traders. It is not very powerful, and its best application is in treating injuries, the flu, and chronic diseases - but it can be good at treating more severe diseases when used by a skilled and/or enhanced doctor. It's not recommended to use herbal medicine for surgery, but you might just about be able to get away with it if your surgeon is fully bionic and of a very good skill level (at least level 12), but don't expect any miracles.

=== Medicine ===
[[{{Q|Medicine|Image}}|left]]
Standard medicine is the benchmark of medical treatment solutions, and is also producible at a [[drug lab]] by combining herbal medicine, [[neutroamine]], and [[cloth]]. It can additionally be purchased from outlanders and orbital traders, and is occasionally dropped by pirate raiders and mercenaries. 

Medicine is best used for treating severe injuries or illnesses. It also works good enough for most surgeries, though the risk of failure is still present. Odds can be improved by as little as a shot of [[go-juice]] or [[luciferium]] for boosted consciousness.

It's not the best idea to excise cancerous growths using ordinary medicine due to its 0.7x success factor and 25% death chance on failure- unless your surgeon has at least a surgery success chance of 128.5% (achievable with a pair of bionic arms) - which translates to a roughly 90% success chance.

=== Glitterworld medicine ===
[[{{Q|Glitterworld medicine|Image}}|left]]
Glitterworld Medicine is the most powerful medicine out of the three types available, and can only be produced on high-tech Glitterworlds. Despite the high price, Glitterworld Medicine carries a value which no other medicine can carry: enhanced medical potency. Naturally, due to the cost, Glitterworld Medicine isn't worth the price for treating trivial diseases or injuries - but it makes surgery ''significantly'' easier, and allows even mediocre doctors to guarantee success in operations.

Whether it be bringing somebody from the jaws of death from the plague or excising cancerous growths, or installing bionics: Glitterworld Medicine is your answer. Injuries and more secure situations with diseases: ordinary medicine will cut it, or even herbal (especially for the former).

== Treatment ==
Basic medical work involving tending to wounds and illnesses. Treating wounds stop them from bleeding and reduce the chance of infections, while tending to illnesses slows them down allowing your colonists' immune systems to catch up and pull ahead.

Each individual treatment can have any quality from 0 - 130%, depending on the medicine used. Higher quality makes infections less likely and slows down illnesses more.

After each treatment there will be text feedback showing the wound/illness tended and the quality of the treatment. Only 1 injury will generate feedback at a time even if multiple are treated at once.

=== Tend quality ===
First, Base Tend Quality is calculated. Then, other factors apply if relevant. Tend Quality is adjusted up to 25% up or down randomly. Finally, the Tend quality is limited to a range between 0% and the Max Tend Quality of the medicine used. 

'''1. Base Tend Quality'''
:<code>'''Base Tend Quality''' = [[Medical Tend Quality|Medical Tend Quality]] × [[Medical Potency]]</code>

:'''1.a. Offsets from hospital bed and vitals monitor'''
::If applicable, Medical Tend Quality Offset from the bed is added to the Base Tend Quality value. This offset only exists on Hospital Beds and Vitals Monitors attached to hospital beds. No other beds have Medical Tend Quality Offset.

::Laying Down is not a factor. Draft tends on injured colonists standing up will have the same Medical Tend Qualities as tends while laying in a standard bed.

::<code>'''Medical Tend Quality with Offset''' = Base Tend Quality + 0.1 Hospital Bed (if applicable) + 0.07 Vitals Monitor (if applicable)</code>

:'''1.b. Self tend factor'''
::If Self Tending, Tend Quality with Offset is adjusted by 70%.

::<code>'''Medical Tend Quality with Self Tend''' = Medical Tend Quality with Offset * 0.7 Self Tend Factor (if applicable)</code>

'''2. Randomization'''
:Medical Tend Quality is then randomized. 

:<code>'''Randomized Tend Quality''' = Medical Tend Quality with Self Tend * Random Value between 0.75 and 1.25</code>

'''3. Maximum tend quality'''
:The Final Tend Quality is then limited to a range of 0 to Maximum Tend Quality from Medicine used.

:<code>'''Final Tend Quality''' = Clamped 0% to Maximum Tend Quality from Medicine</code>

:The maximum tend quality of each medicine is as follows:
:* '''70%''' for {{Icon Small|herbal medicine}} [[herbal medicine]] or no medicine
:* '''100%''' for {{Icon Small|medicine}} [[medicine]]
:* '''130%''' for {{Icon Small|glitterworld medicine}} [[glitterworld medicine]]

'''Notes:'''
* [[Light]] is ''not'' a factor of Medical Tend Quality. It is, however, a factor of [[Global Work Speed]] and thus of Medical Tend Speed and a factor of [[Surgery Success Chance]].
* [[Cleanliness]] is ''not'' a factor of Medical Tend Quality. It is, however, a factor of [[Infection|Infection Chance]].
* Being indoors or outdoors is ''not'' a factor of Medical Tend Quality. It is, however, a factor of cleanliness and thus Infection Chance.

==== Total tend quality ====
Some medical issues are cured when the sum of all tends performed reach a certain value. This is described as "total tend quality". The current total and the required total to cure will be displayed in the mouse-over menu on the issue in question on the pawn's health menu. The value will not be displayed for issues not cured by total tend quality, so its presence is a clear indicator of how to cure the issue. 

The following use this mechanic: 
* [[Gut worms]]
* [[Muscle parasites]]

=== Draft Tending ===
Drafted colonists can be forced to tend wounds of injured pawns using right click. The injured pawn does not need to be laying down in order to be draft tended. One can even Draft Tend an injured pawn on a non-aggressive mental break or a downed enemy in the field. The tend quality of Draft Tended injuries uses the same formula as undrafted treatment. The "Tend (without medicine)" option is useful for emergency treatment. The option "Tend ___" that does not say (without medicine) will use the medicine in the doctor's inventory regardless of the targets medical settings. After using the medicine in inventory, the doctor will grab the nearest medicine of any quality.

== Operations ==
{{Stub|section=1|reason=More complete operations table - rough outline of one available [[User:Harakoni/Sandbox#Operations|here]]}}
[[File:Installing bionic arm.png|right|300px]]
An '''operation''' is a [[bill]] to be performed on a [[colonist]] by a doctor. This may involve the removal or addition of [[body parts]], administration of [[drugs]] or excising [[Carcinoma|carcinomas]]. Many operations require a minimum [[Medical|Medical skill]] (e.g. excising a [[carcinoma]] requires level 10). Some operations require a minimum [[medicine]] level ([[Herbal medicine]] is the minimum required medicine for most operations).

=== Operation Success Rate ===
When an operation is performed, a degree of chance is calculated to assess the probability that the outcome of the operation will be successful.

This is determined as a product of:
* The [[Medical Surgery Success Chance|Surgery Success Chance]] stat of the surgeon performing the operation
* The [[Medical Potency]] stat of the [[Medicine]] used for performing the operation
* The [[Surgery Success Chance Factor]] stat of a [[bed]] or other [[sleep furniture]] upon which the operation is performed
* The [[#Operation Success Rate Multiplier|Success Rate Multiplier]] for the specific operation

This may be expressed as:
<code> '''Operation Success Rate''' = [[Medical Surgery Success Chance|Surgery Success Chance <sub>Surgeon</sub>]] × [[Surgery Success Chance Factor|Surgery Success Chance <sub>Bed</sub>]] × [[Medical Potency]] × [[#Operation Success Rate Multiplier|Operation Success Rate Multiplier]]</code>

Note that additionally:
* The resulting '''Operation Success Rate''' is capped at {{%|0.98}}.
* If the '''Operation Success Rate Multiplier''' is ''Can't fail'', the '''Operation Success Rate''' will always be 100%, regardless of any other stats.

=== Calculating success ===
'''[[Medical Surgery Success Chance|Surgeon stat]]'''
* Determined by Doctoring skill. (see [[#Skill]] section)
* [[Manipulation]] and [[Sight]] act as direct multipliers. For example, 115% Manipulation = x1.15 success.

'''[[Surgery Success Chance Factor|Bed stat]]'''
* Determined by type of bed and its quality. [[Bed]]s and [[bedroll]]s have a modifier of 1.0. [[Hospital bed]]s have a modifier of 1.15. [[Quality]] is a multiplier. Material does not matter. (See [[Surgery Success Chance Factor]])
* Then modified by the room's [[cleanliness]] stat. A multiplier of <code>1.05 + 0.09 * Cleanliness</code>, to a minimum of x0.6. If outdoors, act as minimum cleanliness.
* Then modified by [[light]]. If the head of the bed has a light below 50%, there is a penalty.
* If surgery is done outdoors, there is a further penalty (in addition to the lower Cleanliness).

'''[[Medical Potency|Medical potency]]'''
* Determined by the type of medicine. The [[medicine]] item (industrial medicine) has a modifier of 1.0. (see [[Medical Potency]])

'''Operation Success Rate Multiplier'''
* Modifier dependent on the type of operation.

''Note that the '''Operation Success Rate Multiplier''' for each operation is shown in-game on the '''Information''' page for an added bill in the [[Colonist]]'s '''Health''' -> '''Operations''' tab.''

=== Failure ===
{{Stub|section=1|reason=How are they selected?}}
If an operation fails then the colonist will take damage, and materials (including prosthetics) will be wasted. For lesser failures, damage is concentrated near the site of the operation, while for the ridiculous failures they can be found anywhere in the body.

There are 3 kinds of surgical failure in-game.
*Minor: Deals a little damage, and will not destroy any body parts.
*Catastrophic: Deals great damage, and usually destroys body parts outright.
*Ridiculous: Deals great damage scattered across the entire body.

In addition, each operation has a death on failure chance; when it fails it is possible that the [[colonist]] instantly dies.

=== Available targets ===
Surgeons can perform operations on colonists, prisoners or guests. Performing any kind of violating operation (such as organ removal) on guests will anger the faction.

Tamed animals can be operated on as well, though there are limited options. [[Downed]] non-tamed animals can also be operated on once dragged to an animal sleeping spot.

=== Tips on Improving Success ===
The difference between a level 10 surgeon (93% base surgery success chance) and a level 20 surgeon (99%) is only a 6.5% gain in surgical success rate. The difference between Herbal Medicine (60% potency) and Glitterworld Medicine (160% potency) is a 167% increase in surgical success rate. Room quality has a great impact, too.

Due to the 98% success cap, using glitterworld medicine for surgeries is mostly only worthwhile in lower-quality surgical environments (less cleanliness, lower quality hospital beds, unskilled doctors). Beyond that point, industrial medicine is sufficient for the purposes of surgery.

== Infection ==
When a bed is set to be medical, selecting it shows the infection chance modifier of the room. The overall chance of infection is affected by tend quality, and then multiplied by the aforementioned number. Any bed, no matter what it is, has a 100% modifier on infection when outdoors, and only an incredibly dirty room can get close to this number. However, even at an 80% modifier, wounds tended by an unskilled doctor using herbal meds is likely to be around 10-20% infection chance '''per wound'''. Averting death by a thousand cuts will quickly become agonizing death by 100 infections in such circumstances.

It is much better to make the hospital as clean as possible. Start by covering or removing all natural floors (dirt, sand etc. but excluding stone) and ensure that the hospital is cleaned before tending to pawns. Keep all pawns, especially animals out to keep the room as clean as possible. Infection chance multiplier will likely become around the 40-50% mark or even lower. Next, unlock sterile tiles. A room with 0.6 cleanliness can have multipliers near 30%. To see the cleanliness of rooms, toggle on the room stats view on the bottom right corner and then mouse over the hospital (or any other room for that matter). Dirt, animal filth among other things drastically reduces cleanliness, and it also reduces beauty. This makes it possible to locate and prioritize cleaning through the beauty view. Remember to clean before the treatment when possible.

One of the most difficult things about keeping a hospital clean is bleeding. Bleeding colonists will leave blood on the floor, and blood reduces cleanliness. Someone hemorrhaging to death may create 4 or 5 blood splatters on the floor in a very short time, and if this is happening to multiple colonists after a disastrous raid, your doctor alone may not be enough to keep the room clean. Bring in another colonist or two to clean up after other patients awaiting treatment. What is important is the cleanliness at the time of treatment.

Other things like the presence of hospital beds and better medicine/doctors can reduce infection chance to next to nothing, and make it a non-issue when it does occasionally arise.

== Strategies ==
You will often need to make the most out of the doctors you have, to ensure maximum doctoring efficiency and colonist survival rate/ well-being.

=== Triage ===
You should have doctors prioritize treating patients according to their illness/infection/injury severity.

# Bleeding colonists should receive priority care as they may bleed to death or receive nasty infections. Always prioritize colonists closer to death.
#* Colonists about to die (<1 hours until death) are generally not worth saving unless you have extremely good bionic-enhanced doctors that can reach and patch them up in time.
#** Strip them to recover their clothes so they won't receive the deadman's apparel debuff. How you will deal with the dead colonist is up to you.
#* Colonists that are very close (1-4 hours till death) to dying should have the best doctors care over them.
#* Colonists with around 5-8 hours before death can be treated by regular doctors, or by good doctors without medicine.
#* Colonists with 12 hours or more till death can wait.
# Colonists sick with deadly diseases should also receive priority care, especially those with wound [[infection]]s or the [[plague]].
# Non-bleeding colonists aren't in a great risk of both infections or blood loss; they should be put on the bottom of your priority list.

If left undirected, doctors will automatically tend in order:

# The nearest patients that will die from blood loss in 18 hours
# The nearest human patients
# Himself/herself if self-tend is enabled
# (Feed patients in bed)
# (Surgeries)
# (Rescue downed colonists and pets by taking them to bed)
# The nearest non-human patients

Note that this automatic priority does not take into account the overall severity and lethality of all the illnesses, infections, and injuries afflicting patients, other than the death from blood loss in 18 hours limit. Nor does it prioritize colonists over prisoners or visitors. If imminent death is a concern, it's not a good idea to rely on this default behavior.

=== Medicine allocation ===
Doctors will always tend to use the best medicine possible by default. To counteract this, set colonists' healthcare to Normal medicine or worse. Switch to Glitterworld medicine only if the colonist is down with a fast-working illness and you don't have a decent doctor on board, or they are about to receive a difficult operation.

You can also manually forbid medicine so they will be forced to use lower-tier medicine, so you can save your better medicine for later.

You should try to split your medicine apart into many stacks. If a doctor is about to treat a patient and someone else is getting medicine from a stack, your doctor will use medicine from another stack, or if there's none, he will try to dry-bandage the injured colonist. To combat this, you can draft doctors to go towards the medicine stacks, and manually un-draft and assign them to treat colonists when a doctor is finished taking the medicine.

=== Positioning ===
Medicine should always be put near the hospital. Don't put them right inside the hospital as it reduces beauty unless you're willing to build a shelf to put them in. 
If you're anticipating the need for a treatment, have a doctor stand near your stocks of medicine. You can immediately get the doctor to heal them without having to have him go to the medicine storage and back, saving time. If using primarily herbal meds then it is best to cool the room. It will rarely be necessary to freeze them, but it could make the difference

=== Hospital design ===
[[File:8 hospital beds compact.png|150px|thumb|right|Compact placement of 8 hospital beds around a [[vitals monitor]].]]
{{Stub|section=1|reason=This section is good base but theres room for further develpment}}
* Assuming you're constructing new beds, or comparing beds of the same quality, prioritize [[hospital bed]]s over other bed types, and beds over [[bedroll]]s. Avoid using [[sleeping spot]]s unless necessary. However, also see the note on quality below.
* Compare the stats of the beds placed in the hospital - while Immunity Gain Speed Factor depends solely on the type of bed, Surgery Success Chance Factor is dependent on [[quality]]. A surgery is more likely to succeed on a Good [[Bed]] than an Awful Hospital Bed, but the opposite is true for surviving or recovering from [[diseases]]. 
* A well-equipped hospital will have one or more [[vitals monitor]]s, which give a bonus to several doctoring-related values, including fighting [[infection]]s and general healing.
* [[Sterile tile]]s improve cleanliness and thus outcomes. [[Steel tile]]s offer a lesser but still significant buff, and are significantly more accessible due to lower cost and work requirements, as well as being unlocked by a research project that is far more generally useful. 
* Ensure that that every bed has 50% [[light]] around it. Consider lighting the entire room to allow you to safely place additional sleeping spots in case of overflow.

== Version history ==
* [[Version/0.9.722|0.9.722]] - Surgery can fail now, sometimes catastrophically. Failure chance is related to the surgeon’s medical skill and the quality of the medicine.
* Alpha 17 - It is now possible to change the default healthcare given to pawns. Defaults to best meds for colonists and herbal meds for everybody else.
* Beta 18 - all surgeries now have a minimum 2% chance of failure, no matter how good everything is.
* [[Version/1.3.3159|1.3.3159]] - Display current and required total tend qualities in the tooltip for hediffs with HediffComp_TendDuration comp.
* [[Version/1.3.3200|1.3.3200]] - Total tend quality info is now only displayed if the hediff disappears after a certain level of tend quality (since it's fairly useless otherwise).
