Evidence of expert clinical practice among nuclear medicine non-medical staff: a scoping review.

OBJECTIVE: This scoping review concerns expertclinical practice (ECP) by nuclear medicine practitioners (NMP), encompassing radiographers, technologists and nurses. ECP is typically demonstrated by clinical skills with higher levels of autonomy and responsibility traditionally fulfilled by physicians. The Advanced Clinical Practice (ACP) framework by Health Education England (2017) specifies ECP as one aspect of advanced role progression. This scoping review aims to identify and categorise the extent and type of the existing NMP ECP evidence to support the establishment of Nuclear Medicine ACP. METHODS: PubMed, Cumulative Index to Nursing and Allied Health Literature, and Ovid Medline were searched for peer-reviewed literature published between 2001 and 2021 using extended and advanced practice as key terms alongside nuclear medicine and each NMP profession. Due to the sparsity of results, conference abstracts from prominent international societies were also searched. Studies were independently reviewed and graded for inclusion by four NMP. RESULTS: Of the 36 studies that met the inclusion criteria, 80.6% were conference abstracts and 66.7% were single-centres studies. Commonly reported NM ECP activities included image interpretation, cardiac stressing and therapies. Less reported activities include ordering complementary diagnostic procedures, invasive procedures and physical examinations. The United Kingdom presented itself at the forefront of NMP ECP publications. CONCLUSION: This study demonstrates evidence of NMP ECP across a variety of clinical roles. The dominance of conference abstracts highlights NMP ECP as an emerging area of role extension and a potential preference for information dissemination by NMP. Greater research into specific NMP ECP activities is required particularly studies of greater sample size and robusticity.

Features and impact of dysphagia, dysphonia and laryngeal hypersensitivity in whiplash associated disorder - a qualitative study.

PURPOSE: Investigation into dysphagia, dysphonia and laryngeal hypersensitivity after whiplash is limited, offering minimal insight into specific features and impact. This study aimed to explore these symptoms. MATERIALS AND METHODS: A qualitative interpretive description design was used. Eleven participants with chronic Whiplash Associated Disorder and self-reported swallowing, voice and/or throat-related problems completed baseline symptom questionnaires and were offered a videofluroscopic swallow study to investigate baseline swallowing biomechanics. Semi-structured interviews were conducted to explore features of swallowing, voice and laryngeal sensory complaints and analysed using thematic analysis. RESULTS: There were high baseline levels of self-reported neck, pain- and throat-related disability and psychological distress. There was no evidence of baseline deficits in swallow biomechanics. Thematic analysis revealed 5 themes: (1) A range of features of dysphagia and dysphonia exist after whiplash with varied clinical course; (2) Activity and participation in swallow and voice activities have changed; (3) There are psychological and emotional impacts; (4) Features of laryngeal hypersensitivity co-exist and (5) There are barriers to management. CONCLUSIONS: Swallow, voice and laryngeal sensory problems after whiplash were described, with impacts on quality of life and barriers to management. These insights broaden understanding of post-whiplash sequalae, indicating the need for better detection.Implications for rehabilitationDysphagia, dysphonia and laryngeal hypersensitivity are under-recognised consequences of whiplash.Individuals presenting with dysphagia, dysphonia and laryngeal sensory symptoms after whiplash experience significant implications to wellbeing, activity and participation.Improved understanding of these symptoms may facilitate better detection and subsequent referral to speech-language pathology.Greater understanding into the functional and psychosocial implications of these symptoms may guide more effective post-whiplash assessments and informed rehabilitation.

Regular monitoring of access flow compared with monitoring of venous pressure fails to improve graft survival.

Regular vascular access blood flow (Qa) surveillance is recommended to detect graft stenosis; however, there is little evidence that monitoring and correcting with angioplasty improves graft survival. This blinded, randomized, controlled trial of 112 patients studied time to graft thrombosis and graft loss, comparing monthly Qa plus standard surveillance (dynamic venous pressure and physical examination) (treatment group) to standard surveillance alone (control group). Only the treatment group was referred for angiogram if Qa <650 ml/min or a 20% decrease in Qa from baseline. Percutaneous angioplasty was performed for stenosis >50%. The rate of graft thrombosis per patient-year at risk was 0.41 and 0.51 in the control and treatment groups, respectively. Fifty-one interventions (0.93/patient-years at risk) were performed in the treatment group versus 31 interventions (0.61/patient-years at risk) in the control group. There was no difference in time to graft loss (P = 0.890). In a multivariate analysis, aspirin (ASA) therapy at baseline was associated with an 84% reduction in risk of graft thrombosis (odds ratio [OR], 0.14; P = 0.002). Higher baseline Qa (OR, 0.84; P = 0.05) and longer interval since graft insertion (OR, 0.97; P = 0.07) were associated with a decrease in graft thrombosis. Results reveal that graft surveillance that uses Qa increases the detection of stenosis, compared with standard surveillance; however, intervention with angioplasty does not improve the time to graft thrombosis or time to graft loss.
