Functions (defined or overridden in class RTI):

__init__(name=None, resourcefilepath=None)[source]

Construct a new disease module ready to be included in a simulation.

Initialises an empty parameters dictionary and module-specific random number generator.

Parameters

name – the name to use for this module. Defaults to the concrete subclass’ name.

read_parameters(data_folder)[source]

Reads the parameters used in the RTI module

rti_injury_diagnosis(person_id, the_appt_footprint)[source]

A function used to alter the appointment footprint of the generic first appointments, based on the needs of the patient to be properly diagnosed. Specifically, this function will assign x-rays/ct-scans for injuries that require those diagnosis tools. :param person_id: the person in a generic appointment with an injury :param the_appt_footprint: the current appointment footprint to be altered :return: the altered appointment footprint

initialise_population(population)[source]

Sets up the default properties used in the RTI module and applies them to the dataframe. The default state for the RTI module is that people haven’t been involved in a road traffic accident and are therefor alive and healthy.

initialise_simulation(sim)[source]

At the start of the simulation we schedule a logging event, which records the relevant information regarding road traffic injuries in the last month.

Afterwards, we schedule three RTI events, the first is the main RTI event which takes parts of the population and assigns them to be involved in road traffic injuries and providing they survived will begin the interaction with the healthcare system. This event runs monthly.

The second is the begin scheduling the RTI recovery event, which looks at those in the population who have been injured in a road traffic accident, checking every day whether enough time has passed for their injuries to have healed. When the injury has healed the associated daly weight is removed.

The final event is one which checks if this person has not sought sought care or been given care, if they haven’t then it asks whether they should die away from their injuries

rti_do_when_diagnosed(person_id)[source]

This function is called by the generic first appointments when an injured person has been diagnosed in A&E and needs to progress further in the health system. The injured person will then be scheduled a generic ‘medical intervention’ appointment which serves three purposes. The first is to determine what treatments they require for their injuries and shedule those, the second is to contain them in the health care system with inpatient days and finally, the appointment treats injuries that heal over time without further need for resources in the health system.

Parameters

person_id – the person requesting medical care

Returns

n/a

rti_do_for_major_surgeries(person_id, count)[source]

Function called in HSI_RTI_MedicalIntervention to schedule a major surgery if required. In HSI_RTI_MedicalIntervention, we determine that they need a surgery. In this function, further to scheduling the surgery, we double check that they do meet the conditions for needing a surgery. The conditions for needing a surgery is that they are alive, currently seeking medical intervention and have an injury that is treated by surgery. :param person_id: The person requesting major surgeries :param count: The amount of major surgeries required, used when scheduling surgeries to ensure that two major

surgeries aren’t scheduled on the same day

Returns

n/a

rti_do_for_minor_surgeries(person_id, count)[source]

Function called in HSI_RTI_MedicalIntervention to schedule a minor surgery if required. In HSI_RTI_MedicalIntervention, we determine that they need a surgery. In this function, further to scheduling the surgery, we double check that they do meet the conditions for needing a surgery. The conditions for needing a surgery is that they are alive, currently seeking medical intervention and have an injury that is treated by surgery. :param person_id: The person requesting major surgeries :param count: The amount of major surgeries required, used when scheduling surgeries to ensure that two minor

surgeries aren’t scheduled on the same day

Returns

rti_acute_pain_management(person_id)[source]

Function called in HSI_RTI_MedicalIntervention to request pain management. This should be called for every alive injured person, regardless of what their injuries are. In this function we test whether they meet the requirements to recieve for pain relief, that is they are alive and currently receiving medical treatment. :param person_id: The person requesting pain management :return: n/a

rti_ask_for_suture_kit(person_id)[source]

Function called by HSI_RTI_MedicalIntervention to centralise all suture kit requests. This function checks that the person asking for a suture kit meets the requirements to get one. That is they are alive, currently being treated for their injuries and that they have a laceration which needs stitching. :param person_id: The person asking for a suture kit :return: n/a

rti_ask_for_shock_treatment(person_id)[source]

A function called by the generic emergency appointment to treat the onset of hypovolemic shock :param person_id: :return:

rti_ask_for_imaging(person_id)[source]

A function called by the generic emergency appointment to order imaging for diagnosis :param person_id: :return:

rti_ask_for_burn_treatment(person_id)[source]

Function called by HSI_RTI_MedicalIntervention to centralise all burn treatment requests. This function schedules burn treatments for the person if they meet the requirements, that is they are alive, currently being treated, and they have a burn which needs to be treated. :param person_id: The person requesting burn treatment :return: n/a

rti_ask_for_fracture_casts(person_id)[source]

Function called by HSI_RTI_MedicalIntervention to centralise all fracture casting. This function schedules the fracture cast treatment if they meet the requirements to ask for it. That is they are alive, currently being treated and they have a fracture that needs casting (Note that this also handles slings for upper arm/shoulder fractures). :param person_id: The person asking for fracture cast/sling :return: n/a

rti_ask_for_open_fracture_treatment(person_id, counts)[source]

Function called by HSI_RTI_MedicalIntervention to centralise open fracture treatment requests. This function schedules an open fracture event, conditional on whether they are alive, being treated and have an appropriate injury.

Parameters
  • person_id – the person requesting a tetanus jab

  • counts – the number of open fractures that requires a treatment

Returns

n/a

rti_ask_for_tetanus(person_id)[source]

Function called by HSI_RTI_MedicalIntervention to centralise all tetanus requests. This function schedules a tetanus event, conditional on whether they are alive, being treated and have an injury that requires a tetanus vaccine, i.e. a burn or a laceration.

Parameters

person_id – the person requesting a tetanus jab

Returns

n/a

rti_find_injury_column(person_id, codes)[source]

This function is a tool to find the injury column an injury code occurs in, when calling this funtion you will need to guarentee that the person has at least one of the code you are searching for, else this function will raise an assertion error. To call this function you need to provide the person who you want to perform the search on and the injury codes which you want to find the corresponding injury column for. The function/search will return the injury code which the person has from the list of codes you supplied, and which injury column from rt_injury_1 through to rt_injury_8, the code appears in.

Parameters
  • person_id – The person the search is being performed for

  • codes – The injury codes being searched for

Returns

which column out of rt_injury_1 to rt_injury_8 the injury code occurs in, and the injury code itself

rti_find_all_columns_of_treated_injuries(person_id, codes)[source]

This function searches for treated injuries (supplied by the parameter codes) for a specific person, finding and returning all the columns with treated injuries and all the injury codes for the treated injuries.

Parameters
  • person_id – The person the search is being performed on

  • codes – The treated injury codes

Returns

All columns and codes of the successfully treated injuries

rti_assign_daly_weights(injured_index)[source]

This function assigns DALY weights associated with each injury when they happen.

By default this function gives the DALY weight for each condition without treatment, this will then be swapped for the DALY weight associated with the injury with treatment when treatment occurs.

The properties that this function alters are rt_disability, which is the property used to report the disability burden that this person has and rt_debugging_DALY_wt, which stores the true value of the the disability.

Parameters

injured_index – The people who have been involved in a road traffic accident for the current month and did not die on the scene of the crash

Returns

n/a

rti_alter_daly_post_treatment(person_id, codes)[source]

This function removes the DALY weight associated with each injury code after treatment is complete. This function is called by RTI_Recovery_event which removes asks to remove the DALY weight when the injury has healed

The properties that this function alters are rt_disability, which is the property used to report the disability burden that this person has and rt_debugging_DALY_wt, which stores the true value of the the disability.

Parameters
  • person_id – The person who needs a daly weight removed as their injury has healed

  • codes – The injury codes for the healed injury/injuries

Returns

n/a

rti_swap_injury_daly_upon_treatment(person_id, codes)[source]

This function swaps certain DALY weight codes upon when a person receives treatment(s). Some injuries have a different daly weight associated with them for the treated and untreated injuries. If an injury is ‘swap-able’ then this function removes the old daly weight for the untreated injury and gives the daly weight for the treated injury.

The properties that this function alters are rt_disability, which is the property used to report the disability burden that this person has and rt_debugging_DALY_wt, which stores the true value of the the disability.

Parameters
  • person_id – The person who has received treatment

  • codes – the ‘swap-able’ injury code

Returns

n/a

rti_determine_LOS(person_id)[source]

This function determines the length of stay a person sent to the health care system will require, based on how severe their injuries are (determined by the person’s ISS score). Currently I use data from China, but once a more appropriate source of data is found I can swap this over. :param person_id: The person who needs their LOS determined :return: the inpatient days required to treat this person (Their LOS)

static rti_find_and_count_injuries(persons_injury_properties: pandas.core.frame.DataFrame, injury_codes: list)[source]

A function that searches a user given dataframe for a list of injuries (injury_codes). If the injury code is found in the dataframe, this function returns the index for who has the injury/injuries and the number of injuries found. This function works much faster if the dataframe is smaller, hence why the searched dataframe is a parameter in the function.

Parameters
  • persons_injury_properties – The dataframe to search for the tlo injury codes in

  • injury_codes – The injury codes to search for in the data frame

Returns

the df index of who has the injuries and how many injuries in the search were found.

rti_treated_injuries(person_id, tlo_injury_codes)[source]

The properties that this function alters are rt_injury_1 through rt_injury_8 and the symptoms properties

Parameters
  • person_id – The person who needs an injury code removed

  • tlo_injury_codes – the injury code(s) to be removed

Returns

n/a

on_birth(mother_id, child_id)[source]

on_hsi_alert(person_id, treatment_id)[source]

This is called whenever there is an HSI event commissioned by one of the other disease modules.

report_daly_values()[source]
rti_assign_injuries(number)[source]
A function that can be called specifying the number of people affected by RTI injuries

and provides outputs for the number of injuries each person experiences from a RTI event, the location of the injury, the TLO injury categories and the severity of the injuries. The severity of the injuries will then be used to calculate the injury severity score (ISS), which will then inform mortality and disability from road traffic injuries with treatment and the military abreviated injury score (MAIS) which will be used to predict mortality without medical intervention.

Parameters

number – The number of people who need injuries assigned to them

Returns

injurydescription - a dataframe for the injury/injuries summarised in the TLO injury code form along with data on their ISS score, used for calculating mortality and whether they have polytrauma or not.

Todo: see if we can include the following factors for injury severity (taken from a preprint sent to me after

MOH meeting): - The setting of the patient (rural/urban) as rural location was a predictor for severe injury AOR 2.41 (1.49-3.90) - Seatbelt use (none compared to using AOR 4.49 (1.47-13.76)) - Role of person in crash (Different risk for different type, see paper) - Alcohol use (AOR 1.74 (1.11-2.74) compared to none)

do_rti_diagnosis_and_treatment(person_id)[source]

Things to do upon a person presenting at a Non-Emergency Generic HSI if they have an injury.

class RTIPollingEvent(module)[source]
The regular RTI event which handles all the initial RTI related changes to the dataframe. It can be thought of

as the actual road traffic accident occurring. Specifically the event decides who is involved in a road traffic accident every month (via the linear model helper class), whether those involved in a road traffic accident die on scene or are given injuries (via the assign_injuries function) which they will attempt to interact with the health system with for treatment.

Those who don’t die on scene and are injured then attempt to go to an emergency generic first appointment

This event will change the rt_ properties: 1) rt_road_traffic_inc - False when not involved in a collision, True when RTI_Event decides they are in a collision

  1. rt_date_inj - Change to current date if the person has been involved in a road traffic accident

  2. rt_imm_death - True if they die on the scene of the crash, false otherwise

  3. rt_injury_1 through to rt_injury_8 - a series of 8 properties which stores the injuries that need treating as a

    code

  4. rt_ISS_score - The metric used to calculate the probability of mortality from the person’s injuries

  5. rt_MAIS_military_score - The metric used to calculate the probability of mortality without medical intervention

  6. rt_disability - after injuries are assigned to a person, RTI_event calls rti_assign_daly_weights to match the

    person’s injury codes in rt_injury_1 through 8 to their corresponding DALY weights

  7. rt_polytrauma - If the person’s injuries fit the definition for polytrauma we keep track of this here and use it

    to calculate the probability for mortality later on.

  8. rt_date_death_no_med - the projected date to determine mortality for those who haven’t sought medical care

  9. rt_inj_severity - The qualitative description of the severity of this person’s injuries

  10. the symptoms this person has

Bases: tlo.events.RegularEvent, tlo.events.Event, tlo.events.PopulationScopeEventMixin

Functions (defined or overridden in class RTIPollingEvent):

__init__(module)[source]

Schedule to take place every month

apply(population)[source]

Apply this event to the population.

Parameters

population – the current population

class RTI_Check_Death_No_Med(module)[source]

A regular event which organises whether a person who has not received medical treatment should die as a result of their injuries. This even makes use of the maximum AIS-military score, a trauma scoring system developed for injuries in a military environment, assumed here to be an indicator of the probability of mortality without access to a medical system.

The properties this function changes are: 1) rt_no_med_death - the boolean property tracking who dies from road traffic injuries without medical intervention

  1. rt_date_death_no_med - resetting the date to check the person’s mortality without medical intervention if

    they survive

  2. rt_disability - if the person survives a non-fatal injury then this injury may heal and therefore the disability

    burden is changed

  3. rt_debugging_DALY_wt - if the person survives a non-fatal injury then this injury may heal and therefore the

    disability burden is changed, this property keeping track of the true disability burden

  4. rt_date_to_remove_daly - In the event of recovering from a non-fatal injury without medical intervention

    a recovery date will scheduled

If the person is sent here and they don’t die, we need to correctly model the level of disability they experience from their untreated injuries, some injuries that are left untreated will have an associated daly weight for long term disability without treatment, others don’t.

# todo: consult with a doctor about the likelihood of survival without medical treatment

Currently I am assuming that anyone with an injury severity score of 9 or higher will seek care and have an emergency symptom, that means that I have to decide what to do with the following injuries:

Lacerations - [1101, 2101, 3101, 4101, 5101, 7101, 8101] What would a laceration do without stitching? Take longer to heal most likely Fractures - [‘112’, ‘211’, ‘212, ‘412’, ‘612’, ‘712’, ‘712a’, ‘712b’, ‘712c’, ‘811’, ‘812’]

Some fractures have an associated level of disability to them, others do not. So things like fractured radius/ulna have a code to swap, but others don’t. Some are of the no treatment type, such as fractured skulls, fractured ribs or fractured vertebrae, so we can just add the same recovery time for these injuries. So ‘112’, ‘412’ and ‘612’ will need to have recovery events checked and recovered. Dislocations will presumably be popped back into place, the injury will feasably be able to heal but most likely with more pain and probably with more time Amputations - [‘782’,’782a’, ‘782b’, ‘782c’, ‘882’] Amputations will presumably trigger emergency health seeking behaviour so they shouldn’t turn up here really soft tissue injuries - [‘241’, ‘342’, ‘441’, ‘442’] Presumably soft tissue injuries that turn up here will heal over time but with more pain Internal organ injury - [‘552’] Injury to the gastrointestinal organs can result in complications later on, but Internal bleedings - [‘361’, ‘461’] Surviving internal bleeding is concievably possible, these are comparitively minor bleeds

class HSI_RTI_Medical_Intervention(module, person_id)[source]

This is a Health System Interaction Event. An appointment of a person who has experienced a road traffic injury, had their injuries diagnosed through A&E and now needs treatment.

This appointment is designed to organise the treatments needed. In the __init__ section the appointment footprint is altered to fit the requirements of the person’s treatment need. In this section we count the number of minor/major surgeries required and determine how long they will be in the health system for. For some injuries, the treatment plan is not entirely set into stone and may vary, for example, some skull fractures will need surgery whilst some will not. The treatment plan in its entirety is designed here.

In the apply section, we send those who need surgeries to either HSI_RTI_Major_Surgery or HSI_RTI_Minor_Surgery, those who need stitches to HSI_RTI_Suture, those who need burn treatment to HSI_RTI_Burn_Management and those who need fracture casts to HSI_RTI_Casting.

Pain medication is also requested here with HSI_RTI_Acute_Pain_Management.

Dislocations - Reported in Chagomerana et al. 2017 ‘822a’ Hip dislocation

The properties altered in this function are: rt_injury_1 through rt_injury_8 - in the incidence that despite treatment the person treated is left

permanently disabled we need to update the injury code to inform the model that the disability burden associated with the permanently disabling injury shouldn’t be removed

rt_perm_disability - when a person is decided to be permanently disabled we update this property to reflect this rt_date_to_remove_daly - assign recovery dates for the injuries treated with the surgery rt_injuries_for_major_surgery - to remove codes due to be treated by major surgery when that injury recieves

a treatment.

Bases: tlo.methods.healthsystem.HSI_Event, tlo.events.IndividualScopeEventMixin

Functions (defined or overridden in class HSI_RTI_Major_Surgeries):

__init__(module, person_id)[source]

Create a new event.

Note that just creating an event does not schedule it to happen; that must be done by calling Simulation.schedule_event.

Parameters

module – the module that created this event. All subclasses of Event take this as the first argument in their constructor, but may also take further keyword arguments.

apply(person_id, squeeze_factor)[source]

Apply this event to the population.

Must be implemented by subclasses.

did_not_run(person_id)[source]

Called when this event is due but it is not run. Return False to prevent the event being rescheduled, or True to allow the rescheduling. This is called each time that the event is tried to be run but it cannot be.

class HSI_RTI_Minor_Surgeries(module, person_id)[source]

This is a Health System Interaction Event. An appointment of a person who has experienced a road traffic injury, had their injuries diagnosed through A and E, treatment plan organised by RTI_MedInt and requires minor surgery.

Minor surgeries are defined here as surgeries are generally superficial and do not require penetration of a body cavity. They do not involve assisted breathing or anesthesia and are usually performed by a single doctor.

The injuries treated in this module are as follows:

Evidence for all from Mkandawire et al. 2008: https://link.springer.com/article/10.1007%2Fs11999-008-0366-5 ‘211’ - Facial fractures ‘212’ - Facial fractures ‘291’ - Injury to the eye ‘241’ - Soft tissue injury of the face

‘322’ - Dislocation in the neck ‘323’ - Dislocation in the neck

‘722’ - Dislocated shoulder

External fixation of fractures ‘811’ - fractured foot ‘812’ - fractures tibia/fibula ‘813a’ - Fractured hip ‘813b’ - Fractured pelvis ‘813C’ - Fractured femur The properties altered in this function are: rt_med_int - update to show this person is being treated for their injuries. rt_date_to_remove_daly - assign recovery dates for the injuries treated with the surgery rt_injuries_for_minor_surgery - to remove codes due to be treated by minor surgery when that injury recieves

a treatment.

Bases: tlo.methods.healthsystem.HSI_Event, tlo.events.IndividualScopeEventMixin

Functions (defined or overridden in class HSI_RTI_Minor_Surgeries):

__init__(module, person_id)[source]

Create a new event.

Note that just creating an event does not schedule it to happen; that must be done by calling Simulation.schedule_event.

Parameters

module – the module that created this event. All subclasses of Event take this as the first argument in their constructor, but may also take further keyword arguments.

apply(person_id, squeeze_factor)[source]

Apply this event to the population.

Must be implemented by subclasses.

did_not_run(person_id)[source]

Called when this event is due but it is not run. Return False to prevent the event being rescheduled, or True to allow the rescheduling. This is called each time that the event is tried to be run but it cannot be.

class RTI_Medical_Intervention_Death_Event(module, person_id)[source]

This is the MedicalInterventionDeathEvent. It is scheduled by the MedicalInterventionEvent to occur at the end of the person’s determined length of stay. The risk of mortality for the person wil medical intervention is determined by the persons ISS score and whether they have polytrauma.

The properties altered by this event are: rt_post_med_death - updated to reflect when a person dies from their injuries

Bases: tlo.events.Event, tlo.events.IndividualScopeEventMixin

Functions (defined or overridden in class RTI_Medical_Intervention_Death_Event):

__init__(module, person_id)[source]

Create a new event.

Note that just creating an event does not schedule it to happen; that must be done by calling Simulation.schedule_event.

Parameters

module – the module that created this event. All subclasses of Event take this as the first argument in their constructor, but may also take further keyword arguments.

apply(person_id)[source]

Apply this event to the given person.

Must be implemented by subclasses.

Parameters

person_id – the person the event happens to

class RTI_No_Lifesaving_Medical_Intervention_Death_Event(module, person_id)[source]

This is the NoMedicalInterventionDeathEvent. It is scheduled by the MedicalInterventionEvent which determines the resources required to treat that person and if they aren’t present, the person is sent here. This function is also called by the did not run function for rti_major_surgeries for certain injuries, implying that if life saving surgery is not available for the person, then we have to ask the probability of them dying without having this life saving surgery.

some information on time to craniotomy here: https://thejns.org/focus/view/journals/neurosurg-focus/45/6/article-pE2.xml?body=pdf-10653

The properties altered by this event are: rt_unavailable_med_death - to denote that this person has died due to medical interventions not being available

Bases: tlo.events.Event, tlo.events.IndividualScopeEventMixin

Functions (defined or overridden in class RTI_No_Lifesaving_Medical_Intervention_Death_Event):

__init__(module, person_id)[source]

class RTI_Logging_Event(module)[source]

Bases: tlo.events.RegularEvent, tlo.events.Event, tlo.events.PopulationScopeEventMixin

Functions (defined or overridden in class RTI_Logging_Event):

__init__(module)[source]

Produce a summary of the numbers of people with respect to the action of this module. This is a regular event that can output current states of people or cumulative events since last logging event.

apply(population)[source]

Apply this event to the population.

Must be implemented by subclasses.

Parameters

population – the current population
