Key definitions of community pharmacies’ referral network

Indicator	Definition	Source
Referral uptake (primary outcome)	The actual number of presumptive TB cases visiting the GP clinic after pharmacy referral/total cases referred from community pharmacies	Obtained by matching yellow referral slips collected from PPM-1 clinics to all original slips collected from participating pharmacies
Referral delay	The time period between detailed training (Training 2) of pharmacy staff and the first referral from community pharmacy	By noting the earliest date on an original referral slip
Diagnostic delay	The time period between referral provision to the patient and the patient’s registration at the GP clinic for notified TB cases	By noting the date on an original referral slip and date at which a particular patient reported at a participating PPM-1 clinic
Referral outcome (secondary outcome)	The total number of TB cases notified/total cases referred from community pharmacies × 100	By looking at the national case notification register and matching patients with those referred from the three districts
Referrals generated from brief training	The number of referrals provided by pharmacies after “on the spot” (Training 1 [brief]) but before the second detailed training (Training 2)	By noting the dates on original referral slips and comparing with training dates for a particular pharmacy
Referrals generated from full training	The number of referrals provided by pharmacies after the second detailed training (Training 2)	By noting the dates on original referral slips and comparing with training dates for a particular pharmacy
Pharmacy annual referral rate	The number of referrals made per pharmacy across the year (January–December 2017) in which the project was run	By counting all referrals made by each pharmacy (using original slips collected by cluster facilitators)

GP = general practitioner; TB = tuberculosis; PPM = public–private mix.
