tlo.methods.care_of_women_during_pregnancy module

class CareOfWomenDuringPregnancy(name=None, resourcefilepath=None)

This is the CareOfWomenDuringPregnancy module which contains health system interaction events relevant to

pregnancy and pregnancy loss including:

1.) HSI_CareOfWomenDuringPregnancy_AntenatalCareContact (1-8) representing all 8 routine antenatal care contacts

(ANC) recommended during pregnancy (with sequential scheduling of each event occurring within the HSI)

2.) HSI_CareOfWomenDuringPregnancy_FocusedANCVisit which replicates the pre 2016 structure of ANC (focused ANC)

used in some analysis scripts

3.) HSI_CareOfWomenDuringPregnancy_PostAbortionCaseManagement representing treatment for complications following

abortion (post abortion care of PAC) for women seeking care from the community

4.) HSI_CareOfWomenDuringPregnancy_TreatmentForEctopicPregnancy representing treatment for ectopic pregnancy for

women seeking care from the community

5.) HSI_CareOfWomenDuringPregnancy_AntenatalWardInpatientCare which represents antenatal inpatient care for women

who require admission following complications of pregnancy, detected via ANC or following care seeking from the community including treatment and/or referral for (hypertension, diabetes, antepartum haemorrhage, anaemia, premature of membranes, chorioamnionitis)

Additionally, the module stores a number of HSIs which represent follow up for women who are scheduled for additional testing following an admission and initiation of treatment (i.e. anaemia or gestational diabetes). Individual interventions are stored as functions within the module to prevent repetition.

METADATA : {<Metadata.USES_HEALTHSYSTEM: 3>}

Functions (defined or overridden in class CareOfWomenDuringPregnancy):

__init__(name=None, resourcefilepath=None)

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)

Read parameter values from file, if required.

Must be implemented by subclasses.

Parameters:

data_folder – path of a folder supplied to the Simulation containing data files. Typically, modules would read a particular file within here.

initialise_population(population)

Set our property values for the initial population.

Must be implemented by subclasses.

This method is called by the simulation when creating the initial population, and is responsible for assigning initial values, for every individual, of those properties ‘owned’ by this module, i.e. those declared in its PROPERTIES dictionary.

TODO: We probably need to declare somehow which properties we ‘read’ here, so the simulation knows what order to initialise modules in!

Parameters:

population – the population of individuals

get_and_store_pregnancy_item_codes()

This function defines the required consumables for each intervention delivered during this module and stores them in a module level dictionary called within HSIs

initialise_simulation(sim)

Get ready for simulation start.

Must be implemented by subclasses.

This method is called just before the main simulation loop begins, and after all modules have read their parameters and the initial population has been created. It is a good place to add initial events to the event queue.

care_of_women_in_pregnancy_property_reset(id_or_index)

This function is called following birth/pregnancy loss to reset the variables stored in this module. This prevents women experiencing the effects of these properties in future pregnancies :param id_or_index: individual id OR set of indexes to change the properties :return:

on_birth(mother_id, child_id)

Initialise our properties for a newborn individual.

• child_id – the person id of new child
