Voice handicap Index in Parkinson's patients: Subthalamic versus globus pallidus deep brain stimulation.

PURPOSE: Subthalamic nucleus (STN) and globus pallidus interna (GPI) are the two most common sites for deep brain stimulation (DBS) in people with Parkinson's disease (PWP). Voice impairments are a common symptom of Parkinson's disease and information about voice outcomes with DBS is limited. Most studies in speech-language pathology have focused on STN-DBS and few have examined the effects of GPI-DBS. This was an initial effort to examine the impact of DBS location on Vocal Handicap Index (VHI) scores, which assess the impact of a voice disorder on an individual. METHOD: Twenty-four gender-matched PWP (12 STN-DBS and 12 GPI-DBS) completed the VHI post-DBS implantation. Two-tailed independent samples t-tests were used to compare each VHI scale score (physical, functional, emotional, total) and patient factors between the two groups. RESULTS: No significant differences in total or subscale VHI scores were identified between the two DBS groups. A trend toward greater impairment in PWP with GPI-DBS was noted. An association between higher VHI scores and DBS settings was found. CONCLUSIONS: Studies directly comparing speech outcomes for different DBS targets are lacking. The current findings provide new insights concerning voice outcomes following DBS by adding to the limited literature directly comparing speech outcomes in multiple DBS targets. Limitations and directions for future research are discussed.

Improving Patient Safety and Patient-Provider Communication.

PURPOSE: Many hospitalized patients experience barriers to effective patient-provider communication that can negatively impact their care. These barriers include difficulty physically accessing the nurse call system, communicating about pain and other needs, or both. For many patients, these barriers are a result of their admitting condition and not of an underlying chronic disability. Speech-language pathologists have begun to address patients' short-term communication needs with an array of augmentative and alternative communication (AAC) strategies. METHOD: This study used a between-groups experimental design to evaluate the impact of providing patients with AAC systems so that they could summon help and communicate with their nurses. The study examined patients' and nurses' perceptions of the patients' ability to summon help and effectively communicate with caregivers. RESULTS: Patients who could summon their nurses and effectively communicate-with or without AAC-had significantly more favorable perceptions than those who could not. CONCLUSIONS: This study suggests that AAC can be successfully used in acute care settings to help patients overcome access and communication barriers. Working with other members of the health care team is essential to building a "culture of communication" in acute care settings. SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.9990962.

VFS interjudge reliability using a free and directed search.

Reports in the literature suggest that clinicians demonstrate poor reliability in rating videofluoroscopic swallow (VFS) variables. Contemporary perception theories suggest that the methods used in VFS reliability studies constrain subjects to make judgments in an abnormal way. The purpose of this study was to determine whether a directed search or a free search approach to rating swallow studies results in better interjudge reliability. Ten speech pathologists served as judges. Five clinical judges were assigned to the directed search group (use checklist) and five to the free search group (unguided observations). Clinical judges interpreted 20 VFS examinations of swallowing. Interjudge reliability of ratings of dysphagia severity, affected stage of swallow, dysphagia symptoms, and attributes identified by clinical judges using a directed search was compared with that using a free search approach. Interjudge reliability for rating the presence of aspiration and penetration was significantly better using a free search ("substantial" to "almost perfect" agreement) compared to a directed search ("moderate" agreement). Reliability of dysphagia severity ratings ranged from "moderate" to "almost perfect" agreement for both methods of search. Reliability for reporting all other symptoms and attributes of dysphagia was variable and was not significantly different between the groups.

Ethical issues in dysphagia: when patients refuse assessment or treatment.

The primary goal of intervention for patients with dysphagia is to restore oral feeding. When patients are unable to achieve adequate nutrition, hydration, or safety with oral feeding, then nonoral approaches are often recommended. Although patients' rights to accept or refuse clinical recommendations are widely recognized, when a patient refuses tube feeding or other recommendations, dysphagia specialists are left with a host of practical questions about their role in caring for the patient. We review the criteria for assessing patients' capacity to make informed choices, approaches to decision making when patients lack capacity, and the roles and responsibilities of clinicians when patients choose high-risk treatment options.
