Summary of the four studies that are referred to.
| Ref | Country | Database Source | Research Subjects | Mean Age of Research Subjects | Duration | Key Findings |
|---|---|---|---|---|---|---|
| [18] | USA | Pubmed | 243 AKI 74 non-AKI |
57 (AKI) 56 (non-AKI) |
2007–2010 (4 years) |
AKI was associated with higher frailty (Clinical Frailty Scale). |
| [19] | Korea | Pubmed | 183 (mild frail) 199 (moderate frail) 152 (severe frail) |
73.8 (mild frail) 76.5 (moderate frail) 79.0 (severe frail) |
2013 (1 year) |
The frailest group indicated the highest AKI risk compared with the other groups. |
| [20] | UK | Pubmed | 31 AKI 133 non-AKI |
82.6 (AKI) 81.2 (non-AKI) |
2 weeks | Severe frailty was associated with AKI significantly (p = 0.01). |
| [21] | USA | Pubmed | 93 (non-frail) 139 (pre-frail) 136 (frail) |
68.52 (non-frail) 74.71 (pre-frail) 78.83 (frail) |
2013–2014 (2 years) |
Frail patients were more likely to induce AKI (p = 0.03). |
