A total of 318 Escherichia coli isolates obtained from diarrheic and healthy pigs in Ontario from 2001 to 2003were examined for their susceptibility to 19 antimicrobial agents. They were tested by PCR for the presence of resistance genes for tetracycline, streptomycin, sulfonamides, and apramycin and of 12 common virulence genes of porcine E. coli. Antimicrobial resistance frequency among E. coli isolates from swine in Ontario was moderate in comparison with other countries and was higher in isolates from pigs with diarrhea than in isolates from healthy finisher pigs. Resistance profiles suggest that cephamycinases may be produced by >8% of enterotoxigenic E. coli (ETEC). Resistance to quinolones was detected only in enterotoxigenic E. coli (<3%). The presence of sul3 was demonstrated for the first time in Canada in porcine E. coli isolates. Associations were observed among tetA, sul1, aadA, and aac(3)IV and among tetB, sul2, and strA/strB, with a strong negative association between tetA and tetB. The paa and sepA genes were detected in 92% of porcine ETEC, and strong statistical associations due to colocation on a large plasmid were observed between tetA, estA, paa, and sepA. Due at least in part to gene linkages, the distribution of resistance genes was very different between ETEC isolates and other porcine E. coli isolates. This demonstrates that antimicrobial resistance epidemiology differs significantly between pathogenic and commensal E. coli isolates. These results may have important implications with regards to the spread and persistence of resistance and virulence genes in bacterial populations and to the prudent use of antimicrobial agents.

Importance: The Participation and Environment Measure Plus (PEM+) is a new electronic health application to help caregivers contribute to client-centered and participation-focused care planning for their young child. The PEM+ is designed to help caregivers build on their participation assessment by determining priority activities, setting specific goals, and identifying strategies for goal attainment.Objective: To examine the usability of the PEM+.Design: A single-arm usability trial.Setting: Two early intervention and early childhood educational programs.Participants: Six caregivers of children ages 0-3 yr with developmental delay and receiving rehabilitation services.Intervention: Caregivers who were eligible and enrolled were given access to the PEM+ for 1 wk and instructed to complete one iteration.Outcomes and Measures: Usability was assessed according to caregivers' report of PEM+'s technical effectiveness and ease of use, ease of learning, and user satisfaction via the Usefulness, Satisfaction, and Ease of Use questionnaire.Results: All caregivers completed the PEM+ online once and in its entirety (mean completion time = 13.6 min). Mean technical effectiveness ratings ranged from 5.7 to 6.3 out of 7.0, and mean ease of use, ease of learning, and user satisfaction ratings were 4.4, 5.4, and 4.2 out of 6.0, respectively. Conclusions and Relevance:Caregivers of young children can navigate the PEM+. Trends in survey feedback informed optimizations for the PEM+ before further feasibility testing. What This Article Adds:This study provides preliminary evidence for a promising tool that can help to customize the way practitioners partner with families to create a plan for occupational therapy services.

BackgroundCaregiver input has informed the design of a valid electronic patient-reported outcome (PRO) measure for use in pediatric rehabilitation. This proxy assessment may be further developed to expedite and enhance patient-centered care planning processes, but user input is first needed to finalize the core requirements that will guide its design.ObjectiveThe objective of this study was to examine the feasibility of a stepwise process for building on a baseline assessment of young children's participation in activities to develop a care plan relevant to pediatric rehabilitation.MethodsA cross-sectional descriptive study design was employed using qualitative methods. Data were collected via Web-based technology and by telephone. Twenty-five caregivers of young children (9 with developmental delays, 16 without delays) and between 1 and 7 years were recruited from a subsample of parents who had previously enrolled in a Web-based validation of a PRO on children’s participation and provided consent for future contact. Each caregiver completed a demographic questionnaire and Young Children’s Participation and Environment Measure (YC-PEM) online, followed by a 20- to 60-min semistructured and audiotaped phone interview to review and build upon PRO results as summarized in an electronic report. Interview data were content coded to the interview guide and reviewed by multiple research staff to estimate feasibility according to stepwise completion rates, perceptions of difficulty in step completion, and perceptions of overall utility.ResultsHalf of the participants in the final study sample (N=25) fully completed a stepwise process of building on their baseline PRO assessment to develop an initial care plan for their child. In most cases, similar stepwise completion rates and trends in the approaches taken for step completion were found regardless of the child’s disability status. However, more parents of children with disabilities reported difficulties in rank ordering their priorities for change and identified child-focused strategies for goal attainment. Nearly 77% (19/25) of users were willing to use the process to develop and communicate intervention priorities and strategies with professionals, family, and friends.ConclusionsResults informed revisions to the care planning guide before usability and feasibility testing of an initial Web-based prototype that is now underway.
