Colonisation with pathogenic drug-resistant bacteria and Clostridioides difficile among residents of residential care facilities in Cape Town, South Africa: a cross-sectional prevalence study

Table 2 Univariable and multivariable analysis of risk factors associated with ESBL-E colonisation

	Univariable		Multivariable (n = 117)
Parameter	Odds ratio (95% CI)	P value	Odds ratio (95% CI)	P value
Any incontinence	2.9 (1.2–6.9)	0.019	3.2 (1.3–8.1)	0.013
Katz ADL	1.3 (1.0–1.6)	0.027
Systemic antibiotic exposure last 3 months	1.7 (0.6–4.5)	0.294
Hospital exposure in last 6 months	1.9 (0.8–4.9)	0.143	2.0 (0.8–5.5)	0. 154
Non-ambulatory	2.2 (0.8–5.7)	0.105
Charlson score	1.4 (0.9–2.2)	0.119

Katz ADL score, antibiotic exposure, non-ambulatory status, and Charlson score were dropped from the multivariable model due to P-value exceeding including pre-defined inclusion threshold (P < 0.2). Presence of pressure ulcers was not included as a predictor due to insufficient data (n = 4)
