Number of Studies

Four studies examined OHSMS implementation, 13 assessed OHSMS effectiveness (3 intermediate outcomes, 10 final OHS outcomes, 4 economic outcomes), and 4 addressed facilitators/barriers (1 with quantitative outcomes, 3 with qualitative). As can be seen in Figure 4.1.4, studies that proceeded to data extraction only considered implementation and effectiveness of OHSMSs. None of the studies examining facilitators or barriers were of sufficient quality to proceed to data extraction. This will be discussed further in Section 4.2 below.

Six types of study designs were identified: time series with a concurrent control group (TS – Control), time series without a control group (TS – No Control), before-after, cross-sectional, non-randomized trial (NRT), and studies involving qualitative data. Only two of these designs incorporate a control group (TS – Control and NRT). The majority of studies as shown in Figure 4.1.5, employed time series without control group or before-after designs. None of the studies with qualitative data were of sufficient quality to proceed to data extraction.
