ABSTRACT: Feature at a Glance - Physician sign-out is a mechanism for transferring patient information from one group of hospital caregivers to another at shift changes. Support tools are critical to the success of sign-out. To ensure that a tool is effective, designers must collaborate with end users. Collaboration can be difficult when working with end users who are busy and have irregular schedules. This article reports on a collaborative effort between physicians and engineers to redesign a sign-out support tool. Strategies included focus groups, interviews, "on the fly" feedback, and an iterative design process. Task analysis methods were used to compare the original tool with the prototype in order to quantify any differences in functionality. Last, we discuss general conclusions and offer practical techniques for engaging end-users in the design process.

ABSTRACT: An information prescription is the provision of specific information to a patient on how to help manage a health problem. The Internet is being used increasingly as a source for information prescriptions, with clinicians directing patients to specific Web sites. As with any health care intervention, patients' lack of compliance is a barrier to the effectiveness of Web-based information prescriptions (WebIPs). WebIPs cannot be helpful if patients do not review the information prescribed for them.
The main objective of this study was to quantify the percentage of families who visit a Web site that was specifically prescribed by their physician. In addition, the use of an e-mail reminder was used to determine if it increases the likelihood that families will visit the prescribed Web site. Finally, barriers to accessing the prescribed Web site were identified.
Children were eligible if they presented to the pediatric gastroenterology clinic with chronic constipation and/or encopresis and their family had an active e-mail account and access to the Internet in their home. During their clinic visit, physicians instructed families to visit a Web site that provided educational information pertinent to their child's problem. Families were given a form with the Web-site address and a log-in identification number. Two days after their clinic visit, half of the families received an e-mail reminding them to visit the Web site. Families were contacted 1 week after their clinic visit to identify barriers to accessing the Web site.
Eighty-three families participated in the study. Of the 83 families, 54 (65%) visited the prescribed Web site within 1 week of their clinic visit. Families who received e-mail reminders were significantly more likely to visit the Web site than families who did not receive an e-mail reminder (77% vs 53%). This difference could not be explained by the type or speed of Internet connection or how frequently they accessed the Internet or e-mail. The most common reasons that families cited for not accessing the Web site were "I forgot" and "I didn't have time." Few families cited technical reasons for not accessing the Web site.
Almost two thirds of the families given a WebIP logged on to the prescribed Web site. The probability that families would access the site was increased by 45% with an e-mail reminder. Clearly, e-mail prompts improve compliance to WebIPs. As content and treatment programs continue to proliferate on the Web, it is important to identify barriers and solutions to them to improve overall compliance.

ABSTRACT: This study evaluated the benefits of enhanced toilet training delivered through the Internet for children with encopresis. Twenty-four children with encopresis were randomly assigned to the Internet intervention group (Web) or no Internet intervention group (No-Web). All participants continued to receive routine care from their primary care physician. The Web participants demonstrated greater improvements in terms of reduced fecal soiling, increased defecation in the toilet, and increased unprompted trips to the toilet (ps<.02). Both groups demonstrated similar improvements in knowledge and toileting behaviors. Internet interventions may be an effective way of delivering sophisticated behavioral interventions to a large and dispersed population in a convenient format.

ABSTRACT: To develop and test a scale for parent and child, evaluating theoretical and clinical parameters relevant to children with encopresis. Encopretic children were hypothesized to have more bowel-specific, but not more generic, psychological problems, as compared with nonsymptomatic control children. In addition, mothers were also believed to be more discerning than children.
The Virginia Encopresis-Constipation Apperception Test (VECAT) consists of 9 pairs of bowel-specific and 9 parallel generic drawings. Respondents selected the picture in each pair that best described them/their child. It was administered to encopretic children (N = 87), nonsymptomatic siblings (N = 27), and nonsymptomatic nonsiblings (N = 35). The mothers of all the participants also completed the VECAT. Encopretic children were retested 6 and 12 months posttreatment with Enhanced Toilet Training.
The VECAT demonstrated good test-retest reliability and internal consistency. Encopretic children and their mothers reported more bowel-specific, but not more generic, problems. Bowel-specific scores improved significantly posttreatment only for those patients who demonstrated significant symptom improvement. Mothers were significantly more discerning than children.
The VECAT is a reliable, valid, discriminating, and sensitive test. Bowel-specific problems appear to best differentiate children with and without encopresis.

ABSTRACT: Pediatric constipation/encopresis is thought to be due, in part, to paradoxical constriction of the external anal sphincter (EAS) muscle during attempted defecation. This inappropriate contraction can lead to delayed, impacted, painful, and infrequent bowel movements. Standard Medical Care (SMC) involves disimpaction with enemas, followed by laxative therapy and diet modification, to maintain frequent soft stools. Using the case control method, the efficacy of SMC alone was compared with SMC plus EAS electromyographic biofeedback aimed at eliminating paradoxical contraction. Thirteen consecutive chronically constipated children received SMC plus biofeedback, and were compared with 13 age- and sex-matched children who received only SMC. Biofeedback subjects demonstrated post-treatment elimination of EAS paradoxical constriction. At 16 months follow-up parents of biofeedback children reported significantly greater improvement in constipation, encopresis, laxative use, and painful bowel movements compared to SMC.
