Item Number | Category | Quality Assessment |
---|---|---|
1 | Reporting | The main outcomes of the study to be measured are clearly described in the Introduction or Methods section |
2 | Reporting | The characteristics of the patients included in the study are clearly described (ie. Inclusion and Exclusion Criteria stated, case definition and the source for controls stated in case control studies) |
3 | Reporting | The number/characteristics of non-responders (cross-sectional) or patients lost to follow-up (longitudinal) have been described |
4 | Reporting | The study provides estimates of the random variability in the data for the association of UTI or Bacteriuria and confusion |
5 | Reporting | Actual probability values have been reported for the association between UTI and Delirium eg. p = .035 not p < 0.5, except where p < 0.001 |
6 | Internal Validity | The statistical tests used to assess the association of UTI or Bacteriuria and confusion were appropriate. |
7 | Internal Validity | The distribution of principle confounders in each comparison group were clearly described |
8 | External Validity | Patients asked to participate in the study were representative of the entire population of which they were recruited (source population identified and those asked to participate were either the entire population or a randomised sample of the entire population) |
9 | External Validity | Those participants who were prepared to participate, were representative of the entire population of which they were recruited? > 70% = Yes, < 70% = No |

11 | Criteria | The criteria used to define caseness for UTI was valid and reliable |
12 | Criteria | Criteria for Bacteriuria was described |
13 | Criteria | The criteria used to define caseness for confusion was described |
14 | Criteria | The criteria used to define caseness for confusion was valid and reliable |
