There is a great variation across states in nurse practitioner (NP) scope of practice moderated by state regulations. The purpose of this study was to synthesize the evidence from studies of the impact of state NP practice regulations on U.S. health care delivery outcomes (e.g., health care workforce, access to care, utilization, care quality, or cost of care), guided by Donabedian’s structure, process, and outcomes framework. This systematic review was performed using Medline, CINAHL, PsycINFO, and PubMed according to Preferred Reporting Items for Systematic and Meta-Analysis on the literature from January 2000 to August 2019. The results indicate that expanded state NP practice regulations were associated with greater NP supply and improved access to care among rural and underserved populations without decreasing care quality. This evidence could provide guidance for policy makers in states with more restrictive NP practice regulations when they consider granting greater practice independence to NPs.

Purpose Syllabic diadochokinesis (DDK) is a standard assessment task for motor speech disorders. This study aimed to compare rate and regularity of DDK according to the presence or absence of traumatic brain injury (TBI) and severity of TBI, examine the stability of DDK over time, and explore associations between DDK and extemporaneous speech. Method Military service members and veterans were categorized into three groups: no history of TBI (control), uncomplicated mild TBI (mTBI), and moderate through severe (including penetrating) TBI (msTBI). Participants produced rapid alternating-motion and sequential-motion syllable repetitions during one or two sessions. A semi-automated protocol determined syllabic rate and regularity. Perceptual ratings of selected participants' connected speech samples were compared to DDK results. Results Two hundred sixty-three service members and veterans provided data from one session and 69 from two sessions separated by 1.9 years ( SD = 1.0). DDKs were significantly slower overall for mTBI and msTBI groups compared to controls. Regularity of productions did not differ significantly across groups. A significant Group × Task interaction revealed that the msTBI group produced sequential-motion syllable repetitions but not alternating-motion repetitions with greater regularity, whereas the opposite occurred for control and mTBI groups. DDK results did not differ significantly between sessions. Perceptual speech analysis for 30 participants, including 20 with atypical or questionable DDK performance, revealed two participants with mildly abnormal speech. Conclusions Overall, DDK productions are slower than normal in adults with moderate, severe, and penetrating TBI and are stable over time. Regularity of productions did not differentiate groups, although this result differed according to task. There were surprisingly few people identified with disordered speech, making comparisons to DDK data tenuous, and indicating that dysarthria is a rare complication in a population of adults with mostly uncomplicated mTBI who are not selected from referrals to a speech-language pathology clinic.

Background: Audiology is experiencing pressure from market forces that may change the profession’s nature. Research suggests understanding resistance to change and organizational culture may provide insights that facilitate change. Purpose: This study was designed to examine audiologists’ resistance to change, organizational culture, and clinical practices related to hearing aid pricing and audiology assistants. Research Design: This study utilized a cross-sectional, non-experimental, survey design. Study Sample: Participants were 205 US audiologists, representing diversity across experience, work setting, and location. Data Collection: The study-designed survey examined demographics and clinical practice strategies. Resistance to Change (RTC) scale examined disposition towards change. Organizational Culture Profile (OCP) examined organizational culture perspectives. Results: The majority (52%) of respondents use bundled pricing but 42% of these repondents anticipate transitioning to unbundling. Use of hybrid pricing is increasing. Service-extender personnel were reported by 41%; in addition, 32% who did not report audiology assistants were employed currently, anticipate they will in the future. Results indicated lower resistance to change and greater years of experience were associated with more positive perceptions about organizational culture. Pricing structure was related to experience. Conclusions: Trends indicate use of bundled pricing is decreasing, use of hybrid pricing is increasing, and employment of audiology assistants is increasing. Experienced audiologists are more likely to report unbundled and hybrid pricing compared with less experienced audiologists.
