Interdisciplinary integration of nursing and psychiatry (INaP) improves dizziness-related disability.

OBJECTIVES/HYPOTHESIS: The traditional medical care model of "assess and refer" in a sequential fashion fails to recognize the complexities that arise due to overlapping physical and psychiatric comorbidities experienced by patients with chronic dizziness or imbalance, thus resulting in inadequate treatment outcomes. We aimed to evaluate the impact of a novel interdisciplinary approach to care that integrates nursing and psychiatry (INaP) on dizziness-related disability. STUDY DESIGN: Retrospective cohort study. METHODS: We compared the change in clinical assessment scores (i.e., Dizziness Handicap Inventory [DHI], Dizziness Catastrophizing Scale) at approximately 8 months follow-up between those who did (INaP+) and did not receive INaP (INaP-). Data from 229 patients with dizziness or imbalance referred to an interdisciplinary neurotology clinic in Toronto, Ontario, Canada were acquired from August 2012 to December 2016 and January 2011 to December 2013 for the INaP+ and INaP- groups, respectively. RESULTS: A mean group difference in the percentage change in DHI scores was found, with greater reductions in dizziness-related disability in the INaP+ group (n = 121) versus the INaP- group (n = 108). This remained significant after controlling for age, gender, baseline illness severity, and duration between baseline and follow-up visits. CONCLUSIONS: The novel interdisciplinary approach of incorporating INaP appears to be more effective than interdisciplinary care without INaP in reducing dizziness-related disability in patients with chronic dizziness or imbalance. Clinical settings should consider the addition of INaP to achieve better patient outcomes. Future studies are required to test the hypothesis that INaP is more efficient and cost-effective than the traditional model of care. LEVEL OF EVIDENCE: 3 Laryngoscope, 130:1800-1804, 2020.

Interdisciplinary integration of nursing and psychiatry (INaP) for the treatment of dizziness.

OBJECTIVES: The traditional medical care model of "assess and refer" requires revamping to address the multifaceted needs of patients with chronic dizziness and imbalance by adopting an interdisciplinary approach to care that integrates nursing and psychiatry (INaP). We aim to present a novel interdisciplinary approach that incorporates INaP in the care of patients with chronic dizziness and imbalance. METHODS: Presentation of an interdisciplinary model of care that incorporates INaP provided at the Toronto General Hospital in Toronto, Canada. RESULTS: Interdisciplinary care incorporating INaP, which includes the provision of support from an interdisciplinary health care team (ie, neurotologist, neurologist, psychiatrist, physiotherapist, and nurse clinician), psychoeducation about the interaction between chronic dizziness and psychiatric comorbidities, and ongoing access to medical and psychosocial assessment and intervention, addresses the physical and emotional aspects of patients' experience with chronic dizziness. CONCLUSIONS: The novel comprehensive interdisciplinary approach incorporating INaP may be more effective than interdisciplinary care without INaP in improving clinical outcomes in patients with chronic dizziness. In the subsequent study, we present data comparing patients treated for chronic dizziness and imbalance with and without the integration of INaP in an interdisciplinary setting.

OASIS: The Obesity Awareness and Insight Scale.

AIMS: Impaired illness awareness or not accepting that one has obesity is an understudied phenomenon that may negatively influence treatment adherence and clinical outcomes. The purpose of this study was to perform a systematic review of available measures of obesity awareness, and subsequently develop and validate a novel scale that measures the core domains of obesity awareness. METHODS: A systematic review of the literature revealed no illness specific measure of subjective obesity awareness. As such, we designed the Obesity Awareness and Insight Scale (OASIS) to assess the following core domains of illness awareness: General Illness Awareness,, Symptom Attribution,, Awareness of Need for Treatment and the Negative Consequences attributable to the illness (www.illnessawarenessscales.com). Participants (n=100) were recruited from an online survey platform to assess the psychometric properties of OASIS. RESULTS: The OASIS demonstrated strong internal consistency (Cronbach's alpha=0.89), convergent (r(98)=0.65, p<0.001) and discriminant validity, and test-retest reliability (intra-class correlation=0.76). An exploratory factor analysis of OASIS revealed a single latent component. CONCLUSIONS: OASIS is an obesity-specific instrument that comprehensively measures subjective obesity awareness. OASIS can be used in epidemiological studies, intervention trials and clinical practice to assess the impact of obesity awareness on treatment adherence and outcomes.

BASIS: The blood pressure awareness and insight scale.

Impaired illness awareness or not accepting that one has hypertension (HTN) may be an important predictor of treatment adherence and optimal blood pressure control. The purpose of this study was to perform a systematic review of available instruments to evaluate HTN awareness, and subsequently present a novel scale that measures the core domains of subjective illness awareness in HTN. Based on the absence of any validated HTN specific measure identified through our review, the Blood Pressure Awareness and Insight Scale (BASIS) was developed (www.illnessawarenessscales.com). An online survey platform was used to collect data on 100 participants. BASIS showed good concurrent (r(98) = .65, P < 0.001) and discriminant validity, internal consistency (Cronbach's α = .75), and 1-month test-retest reliability (ICC = 0.77). BASIS is a comprehensive, easy-to-use instrument specifically designed to measure subjective HTN awareness. BASIS may be used in research studies and clinical practice to assess the impact of HTN awareness on treatment adherence and clinical outcomes.

Vestibular stimulation improves insight into illness in schizophrenia spectrum disorders.

Impaired insight into illness (IMP-INS) is common among individuals with schizophrenia spectrum disorders (SSD), contributing to medication nonadherence and poor clinical outcomes. Caloric vestibular simulation (CVS) is typically used to assess peripheral vestibular system function. Left cold CVS is also a transiently effective treatment for IMP-INS and hemineglect secondary to right brain hemisphere stroke, and possibly for IMP-INS and mood stabilization in patients with SSD. Participants with SSD and moderate-to-severe IMP-INS participated in an exploratory double blind, crossover, randomized controlled study of the effects of CVS on IMP-INS. Participants sequentially received all experimental conditions-left cold (4°C), right cold, and body temperature/sham CVS-in a random order. Repeated measures ANOVA were performed to compare changes in IMP-INS, mood and positive symptom severity pre and 30min post CVS. A significant interaction was found between CVS condition, time, and body temperature nystagmus peak slow phase velocity (PSPV) for IMP-INS, indicating that single session left cold CVS transiently improved IMP-INS while right cold CVS may have worsened IMP-INS, particularly in participants with greater vestibular reactivity (i.e. higher PSPV) to body temperature CVS. The procedure's effectiveness is attributed to stimulation of underactive right hemisphere circuits via vestibular nuclei projections to the contralateral hemisphere.
