PurposeThe purpose of this study was to explore the experiences of patients with aphasia, their family members, and physicians related to communication during medical interactions.MethodFace-to-face, semistructured interviews were conducted with 18 participants—6 patients with aphasia, 6 family members involved in patient care, and 6 practicing physicians. A qualitative description approach was used to collect and summarize narratives from participants' perspectives and experiences. Participants were asked about experiences with communication during medical interactions in which the family member accompanied the patient. Interviews were audio- and/or video-recorded, transcribed, and then coded to identify main themes.ResultsPatients and family members generally described their communication experiences as positive, yet all participants discussed challenges and frustrations. Three themes emerged: (a) patients and family members work as a team, (b) patients and family members want physicians to “just try” to communicate with the patient, and (c) physicians want to interact with patients but may not know how.ConclusionsParticipants discussed the need for successful accommodation, or changing how one communicates, to help facilitate the patients' increased understanding and ability to express themselves. Over- and underaccommodation with communication were commonly reported as problems. Speech-language pathologists have a role to play in helping to improve communication during medical interactions. Implications for current speech-language pathologist practice and future directions of research are discussed.

This study was aimed at understanding how the process conditions affected the dimensional stability of glass fiber reinforced PP by microcellular injection molding. A design of experiments (DOE) was performed and plane test specimens were produced for the shrinkage and warpage analysis. Injection molding trials were performed by systematically adjusting six process parameters (i.e., Injection speed, Injection pressure, Shot temperature, SCF level, Mold temperature, and Cooling time). By analyzing the statistically significant main and two-factor interaction effects, the results showed that the supercritical fluid (SCF) level and the injection speed affected the shrinkage and warpage of microcellular injection molded parts the most.
