Background:
Patients in intensive care units (ICUs) may be placed on contact isolation for meticillin-resistant Staphylococcus aureus (MRSA) colonization to prevent transmission. Prior studies suggest that isolated patients may receive substandard care compared with non-isolated patients. An optimal level of sedation is required to facilitate mechanical ventilation (MV) and to minimize adverse outcomes.
Aim:
To determine if patients on MV and isolated for MRSA colonization are at increased risk of oversedation compared with non-isolated patients.
Methods:
Retrospective chart review of adult patients on MV who received an MRSA nasal polymerase chain reaction assay and sedation within 24 and 48 h of ICU admission, respectively. Endpoints included rate of inappropriate sedation, length of ICU stay, length of time on MV, and incidence of ventilator-associated complications.
Findings:
In total, 226 patients were included (114 MRSA positive, 112 MRSA negative). Baseline demographics were similar between the groups, with the exception of ICU admission diagnosis. Fifty-six (55%) isolated patients experienced inappropriate sedation compared with 49 (50%) non-isolated patients (P=0.482). Isolated patients spent longer in the ICU (10.4 vs 6.8 days, P=0.0006), longer on MV (8.98 vs 4.81 days, P<0.001), and required tracheostomies more frequently [37 (32%) vs 14 (13%), P=0.0003] than non-isolated patients.
Conclusions:
Isolated patients were not at increased risk of oversedation compared with non-isolated patients. There was an association between the use of contact isolation for MRSA nares colonization and prolonged ICU stay and prolonged MV.
Insights
Patients on contact isolation for meticillin-resistant Staphylococcus aureus (MRSA) were not oversedated. However, MRSA isolation was associated with longer intensive care unit (ICU) stays and mechanical ventilation (MV) duration.
Area of Science:
- Critical Care Medicine
- Infectious Diseases
- Patient Safety
Background:
- Intensive care unit (ICU) patients with meticillin-resistant Staphylococcus aureus (MRSA) colonization may be placed on contact isolation to prevent transmission.
- Concerns exist that isolated patients may receive suboptimal care, including inappropriate sedation levels, impacting outcomes.
- Optimal sedation is crucial for patients on mechanical ventilation (MV) to ensure comfort and minimize complications.
Purpose of the Study:
- To investigate whether patients on MV and under contact isolation for MRSA colonization experience higher rates of oversedation compared to non-isolated patients.
- To identify potential associations between MRSA isolation and critical care outcomes.
Main Methods:
- A retrospective chart review was conducted on adult patients requiring MV.
- Patients were categorized based on MRSA nasal polymerase chain reaction assay results (positive for isolation, negative for non-isolation).
- Data collected included sedation appropriateness, ICU length of stay, MV duration, and ventilator-associated complications.
Main Results:
- Of 226 patients (114 MRSA positive, 112 MRSA negative), 55% of isolated patients and 50% of non-isolated patients experienced inappropriate sedation (P=0.482).
- Isolated patients had significantly longer ICU stays (10.4 vs 6.8 days, P=0.0006) and MV duration (8.98 vs 4.81 days, P<0.001).
- Tracheostomy rates were higher in the isolated group (32% vs 13%, P=0.0003).
Conclusions:
- Contact isolation for MRSA colonization did not increase the risk of oversedation in mechanically ventilated ICU patients.
- MRSA isolation was significantly associated with prolonged ICU stays and mechanical ventilation.
- Further research may explore strategies to mitigate prolonged resource utilization in isolated patients.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
