Construction of Study Variables^a

Variables	Literature-Based Data for Patient Referral and PDPT	Program-Based Data for DIS Referral
Number of index patients	Number enrolled at baseline in study or evaluation	Number of patients interviewed in STD clinic
Number of partners	Total number of partners claimedb	Total number of partners claimedb
Number of partners notified	Self-report from enrollee (occasional partner corroboration)	Disposition codesc  A: Preventive treatment  B: Refused preventative treatment  C: Infected, brought to treatment  D: Infected, not treated  E: Previously treated  F: Not infected  J: Located, refused testing or treatment
Number of partners treated (or other action indicating partner health is assured)	Self-report from enrollee (occasional partner corroboration)	Disposition codes  A: Preventive treatment  C: Infected, brought to treatment  E: Previously treated  F: Not infected
Notification statistics
(1) Proportion	(1) Number notified/number of partners
(2) Index	(2) Number notified/number of index patients
Treatment index
(1) Proportion	(1) Numbertreated/number of partners
(2) Index	(2) Numbertreated/number of index patients

Abbreviations: DIS, disease intervention specialist; PDPT, patient-delivered partner therapy; STD, sexually transmitted disease.

^aThe number of gonorrhea-infected patients interviewed is not necessarily the total number of gonorrhea-infected cases because not all clinics interview all cases.

^bTotal numbers of partners are not necessarily exclusive because multiple index patients or study enrollees could claim the same partner. The extent to which there is overlap is rarely known.

^cEach of these codes used by STD programs to indicate the outcomes of partner services indicates that the partner was notified by someone even if no other disease intervention took place. With disposition E, the route to notification or treatment may not have been through DIS (other than through assuring treatment took place).
