Hospital bed

A hospital bed improves quality of medical treatments, boosts immunity gain speed to help recover from diseases faster, and speeds up healing from injuries. It can even boost medical tend quality above the normal maximum for that type of medicine, for example allowing 70%+ treatment quality from herbal medicine.

When a colonist that is injured, sick, or has been scheduled for an operation is selected, the player may right-click a hospital bed to direct the colonist there by selecting the "Rest until healed" command (even for elective surgeries). That colonist will then go to that bed and sleep there instead of at their designated beds, and instead of doing their regular tasks. At any time, the colonist can be given another task and, if they can move, they will leave the bed and perform that task.

A hospital bed can also be linked to a vitals monitor to further increase medical treatment quality and patient's immunity gain speed. The bonuses for immunity gain speed from a hospital bed and a vitals monitor stack, but a vitals monitor does not improve the recovery rate from injuries.

While resting on a hospital bed, colonists recover from injuries much faster than a normal bed or sleeping spot. The increased heal rate from using a hospital bed relative to a normal bed is equivalent to a +75% increase in tend quality (see injury for details).

It also increases the success rate of surgeries.

Acquisition

Constructing a hospital bed requires Hospital Bed to be researched and a construction skill of 8. It requires 40 Stuff (Metallic, 400 for SMVs), 80 Steel, 5 Components and is constructed in 2,800 ticks (46.67 secs).

Summary

Rest Effectiveness

Rest Effectiveness is a measure how fast a pawn will regain rest. A pawn sleeping in a bed with 125% rest effectiveness would regain rest 25% faster, and thus require 80% of the time to sleep. Rest effectiveness varies by quality and material. Stone materials only offer 90% of the rest effectiveness of a bed made from non-stone materials at the same quality level.

Quality	Awful	Poor	Normal	Good	Excellent	Masterwork	Legendary
Rest effectiveness	86% (12.21 h)	92% (11.41 h)	100% (10.5 h)	108% (9.72 h)	114% (9.21 h)	125% (8.4 h)	160% (6.56 h)
+ Sleep accelerator	116% (9.04 h)	124% (8.45 h)	135% (7.78 h)	146% (7.2 h)	154% (6.82 h)	169% (6.22 h)	216% (4.86 h)

^{Bracketed numbers are in-game hours to refill rest from 0% to 100% at the given rest effectiveness.}

Comfort

Comfort is a measure of how fast a pawn will refill their comfort meter. A pawn sleeping in a bed with a higher comfort value will regain comfort proportionally faster. Comfort varies by quality but not material. Beds of the same quality level will all have the same comfort, regardless of what they're constructed from. An adjacent end table and a nearby dresser will each increase the base comfort by a further +0.05. This increase is applied before the quality multiplier.

Quality	Awful	Poor	Normal	Good	Excellent	Masterwork	Legendary
Comfort	61%	70%	80%	90%	99%	116%	136%
+ End Table	65%	75%	85%	95%	105%	123%	145%
+ Dresser	65%	75%	85%	95%	105%	123%	145%
+ End Table & Dresser	68%	79%	90%	101%	112%	131%	153%

Surgery Success Chance Factor

The Surgery Success Chance Factor is exactly what it sounds like - a multiplier on the chance for a successful surgery assuming it is performed in this bed. The base value depends on the bed type with most beds having a base value of 100%, the sleeping spot a lower value of 70%, and the hospital bed a higher value of 110%. This base value is then modified by the bed's quality level. Beds of the same type and quality level will all have the same factor, regardless of what they're constructed from.

Quality	Awful	Poor	Normal	Good	Excellent	Masterwork	Legendary
Surgery Success Chance Factor	99	104.5	110	115.5	121	126.5	143

Analysis

When compared to a regular bed:

Pros:

Can be used alongside a vitals monitor, giving further boosts to their medical care
~75% increase in tend quality
10% increased surgery success chance
+0.04 immunity gain speed
6.25% increased comfort
~7.14% more HP

Cons:

Nearly impossible to acquire early game
Much more expensive, requiring 80 steel and 6 components
Requires the Hospital Bed research project
Takes 2.5x longer to construct
Requires level 8 Construction
-1 beauty
~16.67% heavier
Hard cap of 98% surgery success cannot be overcome by any means
Increased Colony Wealth (especially for Legendary quality)

The massive increase in tend quality and surgery success chance makes Hospital beds a worthwhile project to pursue for treatment, especially in maps such as the Tropical Rainforest or Tropical Swamp where diseases like Malaria are much more frequent. A pawn with a high medical skill and Herbal Medicine can suffice for most cases early game, but a hospital bed minimalizes the risk of poor tend results. Since the hospital beds are locked behind a 1200 point research project, as well as needing Sterile Materials (600 points) and Microelectronics (3000 research points), it is not always advised to prioritize them; instead, spend time researching projects that are more immediately necessary for your playthrough. In bedrooms/barracks, using hospital beds is generally not worth the cost, unless the pawn is sickly, very old, or otherwise needs immediate access to quality care in their bedrooms.

^A Bracketed numbers are in-game hours to refill rest to 100% from 0% at the given rest effectiveness.

^B This assumes the hospital bed is inside a clean, properly lit room without a vitals monitor. For the full effects of light, cleanliness, a vitals monitor and placing a hospital bed outside see Surgery Success Chance Factor.
