Summary of findings of QIC studies conducted in nursing home (four studies) and prehospital paramedical care (one study)
| Reference and study design | Topic | Results |
| Baier et al
41 CBA | Pain management | QIC sites improved 3 of 7 pain indicators (appropriate pain assessment 43.8% vs 3.9%, p<0.001; pain intensity scales 73.9% vs 15.6%, p<0.001; non-pharmacological treatments 81.9% vs 40.5%, p<0.001). Prevalence of pain reduced −5% versus −1.5%. |
| Colón-Emeric et al
44 CBA | Falls prevention | No statistical significant difference in fall rates |
| Arling et al
64 ITS with control sites | Falls prevention | Overall 31% decline in mean rate of new falls compared with no changes in control sites |
| Lynn et al
66 ITS with control sites | Pressure ulcer (PU) prevention and care | Compared with national control data, change in prevalence stage I–IV PU not statistically significant. Incidence of new stage III or IV lesions declined 69% from median incidence of 0.3/100 occupied beds per month to 0.0/100 beds (p<0.001). Assessments within 1 day of admission increased from 87% to 99% (p=0.002) and weekly PU documentation from 45% to 67% (p=0.004). |

18 Taljaard et al 108 ITS | Prehospital care for AMI and stroke | Care bundle performance increased from 43% to 79% for AMI (OR 1.04; 1.04–1.04) and from 83% to 96% for stroke (OR 1.06; 1.05–1.07). |
AMI, acute myocardial infarction; CBA, controlled before-after study; ITS, interrupted time series study; QIC, quality improvement collaborative.
