Hospital-associated Clostridium difficile infection and reservoirs within the hospital environment.

BACKGROUND: Clostridium difficile infection (CDI) is a leading cause of hospital-associated infections. Antibiotic stewardship, environmental disinfection, and reduction of transmission via health care workers are the major modes of CDI prevention within hospitals. METHODS: The aim of this study was to evaluate the role of the environment in the spread of CDI within hospital rooms. Bed tracing of positive-CDI inpatients was performed to detect the strength of association to specific rooms. Environmental cultures were conducted to identify adequacy of environmental C difficile (CD) spores. Whole-genome sequencing was performed to evaluate the degree of CD relatedness. RESULTS: Bed tracing performed for 211 CDI patients showed a limited list of high-burden rooms. Environmental cultures for surfaces disinfected with a sporicidal agent were almost entirely negative, whereas the floors were positive for CDI in 15% of the studied patient rooms. Whole-genome sequencing did not detect any close genetic relatedness. CONCLUSIONS: Unlike in an outbreak setting, bed tracing did not yield conclusive results of room reservoirs. The C diff Banana Broth culture was inexpensive, sensitive, and easy to incubate under aerobic conditions. Sporicidal disinfectants were effective in eliminating CD from the environment. CD spores were found on floors and hard-to-clean surfaces.

Measuring client perceptions of motivational interviewing: factor analysis of the Client Evaluation of Motivational Interviewing scale.

Motivational interviewing (MI) is an intervention approach that has solid evidence of efficacy with substance use disorders. Research and training have benefitted from the development of observational measures to assess MI fidelity and competence. However, one untapped area of assessment is the client perception of the clinician use of MI. Client perceptions of MI have been found through qualitative interviews to relate to motivation to change, view of the therapist and safety of therapy. The Client Evaluation of MI (CEMI) scale was developed to assess client perception of clinician MI use. This study further evaluated the CEMI through exploratory and confirmatory factor analysis with a sample of 500 individuals with dual diagnosis pre-discharge from an inpatient unit. Participants completed an MI based session prior to completing CEMIs. A two factor (relational and technical) model explained 51.1% of the cumulative variance and was supported through confirmatory factor analysis. Suggestions for revisions are provided as well as potential uses of the CEMI and future directions for research.

Use of outcomes information in child mental health treatment: results from a pilot study.

OBJECTIVE: This study examined parents and clinicians' use in treatment sessions of routinely collected information on child functioning for children receiving ambulatory mental health treatment. METHODS: Information was obtained from 1,215 Child Outcomes Surveys completed at ten provider organizations. The Child Outcomes Survey is a collaboratively developed brief strength-based measure of child functioning and therapeutic relationship. This study examined parent-clinician discussion of information obtained in the survey from the previous session. Chi square tests were used to examine the association between sociodemographic and clinical covariates and parent-clinician discussion of information. RESULTS: In the measure that assessed the extent to which parents discussed the information about their child's functioning in the prior session with their clinician, 61% of parents reported high levels of discussion, 25% of parents reported moderate levels of discussion, and 14% reported low levels of discussion. Parents of boys, Latino children, and children of "other" races were significantly more likely to report high levels of discussion than other parents. Levels of discussion about the results of the previous Child Outcomes Survey were positively and significantly associated with successful child functioning and therapeutic relationship with clinicians. CONCLUSIONS: The findings of high rates of use of outcomes data routinely gathered with a very brief measure are encouraging given prior reports of challenges in using such information in treatment sessions. The successful treatment of children and families requires an ongoing and effective partnership between parents and clinicians, and the results suggest how important routine conversations about the progress of children in treatment can be. Further research is needed to understand the impact of gathering and using such data on the process and outcomes of mental health treatment for children and families.

The effects of race and racial priming on self-report of contamination anxiety.

African Americans show unusually high endorsement rates on self-report measures of contamination anxiety. The purpose of this study was to replicate this finding in a nationally representative sample and conduct a randomized experiment to determine the effect of salience of race as a causal factor. Black and White participants were given contamination items from two popular measures of obsessive-compulsive disorder, half prior to being primed about ethnic identity and half after being primed, via the administration of an ethnic identity measure. The experiment took the form of a 2 (Black and White participant) X 2 (ethnicity salient and ethnicity non-salient) double-blind design, with ethnic saliency assigned at random by computer. Participants consisted of a geographically representative US sample of African Americans supplemented with a similar sample of European Americans (N=258). Black participants scored significantly higher than White participants on contamination scales. Participants from Southern states scored higher than those from other regions. Over-endorsements by Black participants were greater when awareness of ethnic and racial identification was increased. Clinical and research implications were discussed; these measures should be used with caution in African Americans.
