16Introduction: Early diagnosis and prompt and effective treatment is one of the pillars of malaria 17 control Malaria case management guidelines recommend diagnostic testing before treatment 18 using malaria Rapid Diagnostic Test (mRDT) or microscopy and this was adopted in Nigeria in 19 2010. However, despite the deployment of mRDT, the use of mRDTs by health workers varies 20 by settings. This study set out to assess factors influencing utilisation of mRDT among 21 healthcare workers in Zamfara State, Nigeria.

Methods:A cross-sectional study was carried out among 306 healthcare workers selected using 23 multistage sampling from six Local Government Areas between January and February 2017.
24Mixed method was used for data collection. A pre-tested self-administered questionnaire was 25 used to collect information on knowledge, use of mRDT and factors influencing utilization. An 26 observational checklist was used to assess the availability of mRDT in the six months prior to 27 this study. Data were analyzed using descriptive statistics such as means and proportions.
28Association between mRDT use and independent variables was tested using Chi square while 29 multiple regression was used to determine predictors of use at 5% level of significance. 30 Results: Mean age of respondents was 36.0 ± 9.4years. Overall, 198 (64.7%) of health workers 31 had good knowledge of mRDT; malaria RDT was available in 33 (61.1%) facilities. Routine use 32 of mRDT was reported by 253 (82.7%) healthcare workers. This comprised 89 (35.2%) 33 laboratory scientists/technicians, 89 (35.2%) community health extension workers/community 34 health officers; 59 (23.3%) nurses and 16 (6.3%) doctors. Predictors of mRDT utilisation were 35 good knowledge of mRDT (adjusted OR (aOR):3.3, CI: 1.6-6.7), trust in mRDT results (aOR: 36 4.0, CI: 1.9 -8.2), having being trained on mRDT (aOR: 2.7, CI: 1.2 -6.6), and provision of free 37 mRDT (aOR: 2.3, CI: 1.0 -5.0). 38 Conclusion: This study demonstrated that healthcare worker utilisation of mRDT was associated 39 with health worker and health system-related factors that are potentially modifiable. There is 40 need to sustain training of healthcare workers on benefits of using mRDT and provision of free 41 mRDT in health facilities. 42 43 44 45 46 48 65 gold standard in malaria diagnosis, it has been limited in availability, often of poor quality, time-66 consuming, labor-intensive, and costly 7,8 especially in resource-poor settings. Lack of equipment,67reagents, and expertise for malaria microscopy in the majority of peripheral health centers and 68 the constant power supply has equally limited its use. More so, presumptive diagnosis based on 69 malaria symptoms has proven to be unspecific 9-11 . These shortcomings of microscopy and 70 presumptive diagnosis have favored the deployment and use of mRDTs which have been found 71 to be cost-effective 12-14 and allow diagnosis even in health settings lacking any laboratory 72 facility. Malaria RDT use is expected to not only improve malaria management b...
