Contact precautions for colonisation with multidrug-resistant organisms and haemodialysis patient quality of life and mood: a pilot case-control study

Background: The rate of multidrug-resistant organisms (MDRO) colonisation in dialysis populations has increased over time. This study aimed to assess the effect of contact precautions and isolation on quality of life and mood for haemodialysis (HD) patients colonised with MDRO. Methods: Patients undergoing facility HD completed the Kidney Disease Quality of Life (KDQOL–SFTM), Beck Depression Inventory (BDI) and Personal Wellbeing-Index Adult (PWI-A). Patients colonised with MDRO were case-matched by age and gender with patients not colonised. Results: A total of 16 MDRO-colonised patients were matched with 16 controls. Groups were well matched for demographics and co-morbidities, other than a trend for older dialysis vintage in the MDRO group [7.2 years (interquartile range 4.6–10.0) compared to 3.2 (1.4–7.6) years, p=0.05]. Comparing MDRO-positive with negative patients, physical (30.5±10.7 vs. 34.6±7.3; p=0.2) and mental (46.5±11.2 vs. 48.5±12.5; p = 0.6) composite scores were not different between groups. The MDRO group reported poorer sleep quality (p=0.01) and sleep patterns (p=0.05), and lower social function (p=0.02). BDI scores were similar (MDRO-positive 10(3.5–21.0) vs. MDRO-negative 12(6.5–16.0), p=0.6). PWI-A scores were also similar in both groups; however, MDRO patients reported lower scores for “feeling safe”, p=0.03. Conclusion: While overall scores of quality of life and depression were similar between groups, the MDRO group reported poorer outcomes in sleep and social function. A larger cohort and qualitative interviews may give more detail of the impact of contact precautions and isolation on HD patients. The necessity for contact precautions for different MDRO needs consideration.
