Data source	Data collection period	Methods, sample size, data elements, limitations
FCHV Survey	Aug 2014 – Feb 2015	Nationally representative FCHV survey; analysis included 42 districts in which chlorhexidine had been introduced. N=2,626 FCHVs.
		This data source was used to assess availability of chlorhexidine with FCHVs, and their reported frequency of dispensing chlorhexidine.
		Dispensing information is based solely on FCHV self-report.
Health Facility Survey	April – Nov 2015	Nationally representative sample of facilities offering childbirth services. N=457. Health facilities assessed in this survey included all public-sector hospitals, all larger volume private hospitals, and a representative sample of lower level public facilities.
		It was used in our analysis to determine chlorhexidine stock status.
Nepal Demographic & Health Survey 2016 (NDHS)	Jun 2016 – Jan 2017	National multi-stage household cluster survey, representative sample of RDWs (2yr). N=1,978. Note that, at the time of the survey, chlorhexidine had been introduced in 56 /75 districts.
		Chlorhexidine applied according to mother (by place of birth)
		For facility births, mothers were not necessarily aware of all procedures done on newborn.
Health Management Information System (HMIS)	July 2016 – July 2017	National reporting data, as documented in the Department of Health Services Annual Report 2073-4. The HMIS is the Ministry’s integrated routine health information system that captures data elements from community level (including FCHV reports), peripheral health facility level, and hospital level (including private hospitals participating in the government’s free maternity care program).
		Additional data elements for chlorhexidine include: 1) FCHV reports on chlorhexidine use following home births; and 2) HF reports on chlorhexidine use following institutional births.
		FCHVs only reach a fraction of mothers after birth, so may not accurately report on chlorhexidine use at home births.
National Chlorhexidine Coverage & Compliance survey	April – Aug 2017	Multi-stage household cluster survey, representative sample of RDWs (1yr) in 56 program districts. N=3,661.
		Chlorhexidine received during pregnancy, chlorhexidine applied, according to mother’s report (by place of birth)
		For facility births, mothers were not necessarily aware of all procedures done on newborn.
