Evaluating the impact of results-based motivating system on noncommunicable diseases risk factors in Iran: Study protocol for a field trial.

Risk factors of noncommunicable diseases (NCD) are increasingly contributing to morbidity and mortality in Iran. Health care providers' competencies and motivation are essential factors for the success and efficiency of primary health care. This field trial aims to evaluate the impact of a results-based motivating system on population level of the NCD risk factors field trial (IRPONT) in Iran. Population groups of 24 rural or urban catchment areas from 3 provinces were randomized to 1 of the 4 types of study groups. The groups were defined based on a set of 4 intervention packages. Extra 8 rural or urban catchment areas in a separate city were considered as independent nonintervention (control) group. Population levels of major NCD risk factors in all 32 population groups were measured at the beginning of the trial, at the end of the first year, and will be measured in the second year through standardized population surveys. As the outcome measure, the difference in population levels of the risk factors will be compared among the study groups. Study group IV will be compared with combined control groups (study groups I, II, and III). Also, we will conduct subgroup analysis to determine the effects of interventions 2, 3, and 4. This trial has received ethical approval from National Institute for Medical Research Development in Iran (IR.NIMAD.REC.1396.084) in 2017. This trial has been registered on the Iranian Registry of Clinical Trials (identifier: IRCT20081205001488N2). Registered on 3 June 2018 and updated on 12 April 2020.
