Associations between vascular comorbidity groups and higher multidrug counts
| Conditions | Multidrug number/10 000 population |
Adjusted OR (95% CI) | |||||
|---|---|---|---|---|---|---|---|
| 0 | 1 | 2 | 3 | 4 | 5 | ||
| Vascular group only* | 199 | 2373 | 4018 | 2547 | 773 | 89 | 1.0 |
| Vascular group and COPD | 85 | 677 | 2854 | 4207 | 2008 | 169 | 4.63 (3.8 to 5.7) |
| Prevalence ratio | 0.43 | 0.29 | 0.71 | 1.65 | 2.60 | 1.90 | |
| Vascular group and OA | 29 | 873 | 3493 | 3697 | 1557 | 349 | 3.01 (2.6 to 3.5) |
| Prevalence ratio | 0.15 | 0.37 | 0.87 | 1.45 | 2.01 | 3.92 | |
| Vascular group and Depression | 69 | 829 | 3733 | 3917 | 1359 | 92 | 3.22 (2.6 to 3.9) |
| Prevalence ratio | 0.35 | 0.35 | 0.93 | 1.54 | 1.76 | 1.03 | |
*Vascular group only is the reference group without COPD, OA or depression; prevalence ratio is comparing vascular comorbid group with vascular group alone for each drug count category, adjusted for age, gender and deprivation and estimates are with the ‘outcome’ of higher drug count (3–4 combined) compared with lower drug counts (2 or less).
COPD, chronic obstructive pulmonary disease; OA, osteoarthritis.
