co: distinguish essential and optional consumables

[EvaJanouskova]

Currently we don't distinguish essential and optional consumables for contraception methods, we assume all consumables are essential now. This needs to be updated!

[EvaJanouskova]

@tbhallett, is this necessary to be done soon-ish, or could this wait?

[tbhallett]

It depends. The most important thing is that we don't want these changes to affect the calibration of the contraception module. (Or if they do, and they are going to be permanent, then the contraption module would need to be recalibrated).

[EvaJanouskova]

It might change the calibration but we should do it sometime but I think we could put it off until later.?

[tbhallett]

We can't put anything into master that changes the calibration as people need that to be stable for their analysis. The contraception module is especially critical, as it affects the demography and so influence all the other model results.

So, we have to be sure that the change being made by your current PRs are invisible from the point-of-view of the calibration plots. The changes to consumables (the number of items) will be fine, as will adding of Equipment definitions. But - any changes to consumables items (changing codes, or adding non-optional items), we will have to carefully check by running the simulation and looking at the results.

[EvaJanouskova]

If the calibration is based on default availability (Is it?), we made already a few changes which may slightly alternate the calibration within the PR #1298:

master

• one item for both type of pills (item code 1: Ethinylestradiol 0.03mg + levonorgestrel 0.15mg_Each_FP000800_CMST, cycle //80% patients//; or Microlut (Levonorgestrel 0.03mg)_Each_FP004200_CMST, cycle //20% patients//), hence availability based on item 1
• one item for both type of implants (item code 12: Jadelle(implant)_Each_FP003700_CMST, 2 rods //50% patients//; or Implanon (Etonogestrel 68mg)_Each_FP004100_CMST, 1 rod //50% patients//), hence availability based on item 12
• item 307: Atropine sulphate 600 micrograms/ml, 1ml_Each_BB006600_CMST //1 unit 50% patients → 0.5 units per case// - 0.5 units used, hence the availability always checked
• new items 2676: Polyamide monofilament suture sterile 1, on 40mm 3/8 circle reverse cutting needle_12_GG005100_CMST and 2677: Catgut chromic suture sterile 0, 75cm, round bodied ½ circle 40mm needle_12_GG000600_CMST used for female sterilisation

#1298

• two different items, one for each type of pills (item 0: Levonorgestrel 0.0375 mg, cycle, item 1: Levonorgestrel 0.15 mg + Ethinyl estradiol 30 mcg (Microgynon), cycle), hence the availability based on item 0 or item 1 according to which item is chosen by probability 20% : 80%
• two different items, one for each type of implant (item 12: Jadelle (implant), box of 2_CMST, item 13: Implanon (Etonogestrel 68 mg), hence the availability based on item 12 or item 13 according to which item is chosen by probability 50% : 50%
• item 307: Atropine sulphate 600 micrograms/ml, 1ml_each_CMST - used in 50% cases based on probability, hence the availability checked only in 50% cases of female sterilisation
• existing items 19: Needle, suture, assorted sizes, round body and 20: Suture, catgut, chromic, 0, 150 cm used for female sterilisation

So maybe we should add the TODO to check the calibration in the #1298?

This is rolled back now in #1298.

@EvaJanouskova can we close this?

[EvaJanouskova]

Don't you think the consumables for contraceptives should be distinguished as essential X optional in future along with calibration check/update? If not we can close this issue. However, if you agree that it should be done once, we may keep the issue open as a reminder this needs to be addressed.

[tbhallett]

Yes if you still think it's relevant (it will be indeed, if there are consumables currently labelled as being essential that are not actually essential), then please do keep it open and assign it to yourself.

Certainly, some items should be optional but were coded as essential.
