To assess preventability of hospital-onset bacteremia and fungemia (HOB), we developed and evaluated a structured rating guide accounting for intrinsic patient and extrinsic healthcare-related risks.
Design:
HOB preventability rating guide was compared against a reference standard expert panel.
Participants:
A 10-member panel of clinical experts was assembled as the standard of preventability assessment, and 2 physician reviewers applied the rating guide for comparison.
Methods:
The expert panel independently rated 82 hypothetical HOB scenarios using a 6-point Likert scale collapsed into 3 categories: preventable, uncertain, or not preventable. Consensus was defined as concurrence on the same category among ≥70% experts. Scenarios without consensus were deliberated and followed by a second round of rating.
Two reviewers independently applied the rating guide to adjudicate the same 82 scenarios in 2 rounds, with interim revisions. Interrater reliability was evaluated using the κ (kappa) statistic.
Results:
Expert panel consensus criteria were met for 52 scenarios (63%) after 2 rounds.
After 2 rounds, guide-based rating matched expert panel consensus in 40 of 52 (77%) and 39 of 52 (75%) cases for reviewers 1 and 2, respectively. Agreement rates between the 2 reviewers were 84% overall (κ, 0.76; 95% confidence interval [CI], 0.64–0.88]) and 87% (κ, 0.79; 95% CI, 0.65–0.94) for the 52 scenarios with expert consensus.
Conclusions:
Preventability ratings of HOB scenarios by 2 reviewers using a rating guide matched expert consensus in most cases with moderately high interreviewer reliability. Although diversity of expert opinions and uncertainty of preventability merit further exploration, this is a step toward standardized assessment of HOB preventability.
To determine the association between contact precautions and depression or anxiety as well as feelings of anger, sadness, worry, happiness, or confusion.
Design.
Prospective frequency-matched cohort study.
Setting.
The University of Maryland Medical Center, a 662-bed tertiary care hospital in Baltimore, Maryland.
Participants.
A total of 1,876 medical and surgical patients over the age of 18 years were approached; 528 patients were enrolled from January through November 2010, and 296 patients, frequency matched by hospital unit, completed follow-up on hospital day 3.
Results.
The primary outcome was Hospital Anxiety and Depression Scale (HADS) scores on hospital day 3, controlling for baseline HADS scores. Secondary moods were measured with visual analog mood scale diaries. Patients under contact precautions had baseline symptoms of depression 1.3 points higher (P < .01) and anxiety 0.8 points higher (P = .08) at hospital admission using HADS. Exposure to contact precautions was not associated with increased depression (P = .42) or anxiety (P = .25) on hospital day 3. On hospital day 3, patients under contact precautions were no more likely than unexposed patients to be angry (20% vs 20%; P = .99), sad (33% vs 38%; P = .45), worried (51% vs 46%; P = .41), happy (58% vs 67%; P = .14), or confused (23% vs 24%; P = .95).
Conclusions.
Patients under contact precautions have more symptoms of depression and anxiety at hospital admission but do not appear to be more likely to develop depression, anxiety, or negative moods while under contact precautions. The use of contact precautions should not be restricted by the belief that contact precautions will produce more depression or anxiety.
To investigate the relationship between contact precautions and delirium among inpatients, adjusting for other factors.
Design.
Retrospective cohort study.
Setting.
A 662-bed tertiary care center.
Patients.
All nonpyschiatric adult patients admitted to a tertiary care center from 2007 through 2009.
Methods.
Generalized estimating equations were used to estimate the association between contact precautions and delirium in a retrospective cohort of 2 years of admissions to a tertiary care center.
Results.
During the 2-year period, 60,151 admissions occurred in 45,266 unique nonpsychiatric patients. After adjusting for comorbid conditions, age, sex, intensive care unit status, and length of hospitalization, contact precautions were significantly associated with delirium (as denned by International Classification of Diseases, Ninth Revision), medication, or restraint exposure (adjusted odds ratio [OR], 1.40 [95% confidence interval {CI}, 1.24–1.51]). The association between contact precautions and delirium was seen only in patients who were newly placed under contact precautions during the course of their stay (adjusted OR, 1.75 [95% CI, 1.60–1.92]; P< .01) and was not seen in patients who were already under contact precautions at admission (adjusted OR, 0.97 [95% CI, 0.86–1.09]; P = .60).
Conclusions.
Although delirium was more common in patients who were newly placed under contact precautions during the course of their hospital admission, delirium was not associated with contact precautions started at hospital admission. Patients newly placed under contact precautions after admission but during hospitalization appear to be at a higher risk and may benefit from proven delirium-prevention strategies.
Knowledge of the prevalence and correlates of personality disorders in the community is important for identifying treatment needs and for provision of psychiatric services.
Aims
To estimate the prevalence of personality disorders in a community sample and to identify demographic subgroups with especially high prevalence.
Method
Clinical psychologists used the International Personality Disorder Examination to assess DSM-IV and ICD-10 personality disorders in a sample of 742 subjects, ages 34–94 years, residing in Baltimore, Maryland. Logistic regression was used to evaluate the association between demographic characteristics and DSM — IV personality disorder clusters.
Results
The estimated overall prevalence of DSM — IV personality disorders was 9%. Cluster A disorders were most prevalent in men who had never married. Cluster B disorders were most prevalent in young men without a high school degree, and cluster C disorders in high school graduates who had never married.
Conclusions
Approximately 9% of this community sample has a DSM-IV personality disorder. Personality disorders are over-represented in certain demographic subgroups of the community
