Rare Symptoms Hospital: Diagnostic and Treatment Procedures

Hospital House MD

HospitalHouseMD HospitalHouseMD - - EDG HospitalHouseMD is a hospital that accepts patients with rare, and often unexplainable symptoms. Patients are assigned one or more doctors, which try to make a diagnosis for the sick patient. For each illness HospitalHouseMD has a database with all possible treatments. These treatments can be applied to any diagnosis and are accordingly executed. Template Treatment, as described in the handbook/ database Applied Treatment, i.e. the treatment as it will be applied to a patient.

FSM of Diagnosis To keep everything under control, the head doctor has to approve the diagnosis made by another doctor before any treatment can happen.

Diagnosis FSM While the requirements are relatively clear about approval, the requirements about an unapproved diagnosis are not clear. Is this the same as an "exists" diagnosis ? Can the AppliedTreatment already be created (proposed) in the exists state, to be executed in the approved state? Several solutions are thus possible depending on the answers to the above questions. This solution assumes that 1. 'exists' is not the same as 'disapproved' 2. that in the 'exists' state the treatments can already be added to the diagnosis but not yet "happen". That distinction needs then to be managed in the BP Layer. If this assumption is wrong, the MEcrAppliedTreatment and MEendAppliedTreatment methods need to be removed from the self- transition in the exist state

FSM of Applied Treatment An applied treatment can go through three stages. The first stage is the weakest treatment. In this stage, no consent is necessary by the patient, and the applied treatment can start immediately. When this doesn t work, the applied treatment needs to move to stage 2 or even directly to stage 3, according to the rules described below. To move the applied treatment from stage 1 to another stage, consent is needed by the patient. The patient needs to sign a form indicating his/her consent to move his/her applied treatments to a higher stage. Once this consent has been given, any applied treatment for that patient can be moved to a higher stage, without the need to ask consent again. So, once a consent is signed by the patient, all applied treatments can freely upgrade from stage 1 to 2 and 3, until the patient retracts his/her consent. Patients with an applied treatment in stage 3 require a higher follow-up rate and will be checked more often by nurses and doctors. Once the higher follow-up rate isn t needed anymore for a specific applied treatment for a patient, the applied treatment can downgrade again to lower stages (downgrading is the responsibility of the doctor). Remark: the word "applied" has been added to the text to clarify that this behaviour describes what happens to the specific treatment of a patient, what was called "AppliedTreatment" in de EDG. This is not the behaviour of the "template" Treatment (called "Treatment" in the EDG).

FSM of AppliedTreatment

FSM of Illness Illnesses also get a priority score, this is necessary to prevent any outbreaks from e.g. unknown viruses. The priority score of an illness can change at any given time. For now HospitalHouseMD only has two priority scores: high and low. When an illness gets priority score high, all applied treatments for that illness are immediately placed into stage 3, by means of a priority stage upgrade. No consent of the patients are needed to move the treatment to stage 3 when the priority score of the illness is high.

FSM of Patient The patient needs to sign a form indicating his/her consent to move his/her applied treatments to a higher stage. Once this consent has been given, any applied treatment for that patient can be moved to a higher stage, without the need to ask consent again. So, once a consent is signed by the patient, all applied treatments can freely upgrade from stage 1 to 2 and 3, until the patient retracts his/her consent.
