Diagnosis

While certain illnesses may seem abundantly clear from your lofty perch as administrator, all patients that enter the hospital must go through the process of Diagnosis. This begins with a visit to the GP's Office, where the Doctor will interview the Patient. At the end of the appointment, the patient's Diagnosis Certainty will increase. If the Illness is not diagnosed at this time, the Patient will be sent on to other Diagnosis Rooms to increase Diagnosis Certainty. Which room they are sent to depends on the illness and the doctor's level: Student Doctors are inexperienced and may send the patient to any diagnosis room, while, with each promotion, a doctor's chance to send the patient to a room that is good at diagnosing their illness increases, with a Senior Consultant always prioritizing the best rooms, assuming they are present at the hospital. It is important to note that only a doctor's level factors into this decision, while their diagnosis skill does not.

After each appointment at a Diagnosis Room, the Patient will return to a GP's Office and be sent into other Diagnosis Rooms until Diagnosis Certainty reaches the minimum amount set in the Policy Screen (default is 90%). Once it reaches the minimum amount, the patient will be sent for Treatment. The Fast-Track Decision option in the Policy Screen allows any diagnosis doctor or nurse to send the patient for treatment, whereas, if the option is turned off, like it is by default, the patient may only be sent for treatment by a GP.

Additionally, at any point during this process, the player may prematurely send the patient for Treatment if Diagnosis Certainty is at least 50% by clicking the "Send for Treatment" button on the Patient's Information Tab. However, players must be careful, as Diagnosis Certainty factors into the Treatment's success chance.

Diagnosis Rooms
These are the rooms used to diagnose the various Illnesses.

Diagnosis Modifiers
The amount by which Diagnosis Certainty is increased by each visit to a Diagnosis Room is dependent on two factors: the illness's diagnosis modifier in that specific room (which is a percentage), and the cumulative diagnosis percentage of the doctor/nurse, machine upgrades (if any), and items in the room (if any). The increase in Diagnosis Certainty will be the diagnosis modifier (percentage) of the cumulative diagnosis.

Let's take Lycanthropy as an example:

After checking in, they make their way into a GP's Office with two Medicine Cabinet (2% Diagnosis), where a Senior Consultant (120% Diagnosis) trained in General Practice V (75% Diagnosis) attends to them. Once processed, they receive 30% of the cumulative diagnosis (197%) of the doctor and items, which is 59.1%. Since the GP is a Senior Consultant, they send the patient to the room with the highest modifier for their illness, which, in this case, would be either Cardiology or Fluid Analysis, if they are available.

The patient makes their way to, for example, Cardiology, where an untrained Student Nurse (80% Diagnosis) is working with a Heart Racer that has been upgraded once (25% Diagnosis). Once processed, they receive 41% of the cumulative diagnosis (105%) of the nurse and machine, which is 43%, raising the Diagnosis Certainty to the maximum of 100%.
