Trajectories and Predictors of Raised State Anxiety Among Outpatients Who Have Undergone Medical Imaging Procedures.

PURPOSE: The aim of this study was to examine the prevalence of raised state anxiety before and after medical imaging procedures, the prevalence of state anxiety trajectories, and factors associated with postprocedural raised state anxiety. METHODS: A prospective survey was administered to outpatients undergoing elective medical imaging procedures (CT, radiography, MRI, ultrasound, angiography, or fluoroscopy) recruited from one center. Participants completed a self-report survey preprocedure (time 1) and postprocedure (time 2). State anxiety was measured using the six-item State-Trait Anxiety Inventory. The point prevalence of raised state anxiety (State-Trait Anxiety Inventory score ≥33.16) at time 1 and time 2 was calculated, as was the prevalence of four state anxiety trajectories over time: persistent low anxiety, decreasing anxiety, increasing anxiety, and persistent raised anxiety. Factors predictive of raised state anxiety at time 2 were examined using logistic regression analysis. RESULTS: Three hundred fifteen participants completed both surveys. The prevalence of raised state anxiety at time 1 (50%) and time 2 (51%) was similar. Most patients reported persistent raised anxiety (36%) and persistent low anxiety (34%) over time. Fewer patients reported increasing anxiety (15%) and decreasing anxiety (14%). Raised state anxiety (odds ratio, 4.84; 95% confidence interval, 2.48-9.48) and lower reported health status (odds ratio, 2.48; 95% confidence interval, 1.11-5.51) at time 1 were significantly associated with greater odds of raised anxiety at time 2. CONCLUSIONS: Raised state anxiety related to medical imaging procedures is common among outpatients. Half of patients either developed or continued to experience raised anxiety after their procedures. Outpatients may benefit from evidence-based methods of alleviating anxiety before their procedures.

Medical Imaging Outpatients' Experiences With Receiving Information Required for Informed Consent and Preparation: A Cross-Sectional Study.

BACKGROUND: Medical imaging outpatients often experience inadequate information provision and report high levels of anxiety. However, no studies have assessed patients' receipt of preparatory information in this setting. OBJECTIVE: To examine medical imaging outpatients' perceived receipt or non-receipt of preparatory information from health professionals and imaging department staff prior to their procedure. METHOD: Computed tomography and magnetic resonance imaging outpatients at one Australian hospital self-completed a touchscreen computer survey assessing their perceived receipt of 33 guideline-recommended preparatory information items. RESULTS: Of 317 eligible patients, 280 (88%) consented to participate. Eight percent (95% confidence interval: 5%-12%) of participants reported receiving all information items. The median number of information items not received was 18 (interquartile range: 8-25). Items most frequently endorsed as "not received" were: how to manage anxiety after (74%) and during the scan (69%). Items most commonly endorsed as "received" were: reason for referral (85%) and how to find the imaging department (74%). CONCLUSION: Few medical imaging outpatients recalled receiving recommended preparatory information. Preparatory communication needs to be improved to better meet patient-centered service imperatives.

Raised Anxiety Levels Among Outpatients Preparing to Undergo a Medical Imaging Procedure: Prevalence and Correlates.

PURPOSE: To examine the percentage of patients with raised state anxiety levels before undergoing a medical imaging procedure; their attribution of procedural-related anxiety or worry; and sociodemographic, health, and procedural characteristics associated with raised state anxiety levels. MATERIALS AND METHODS: This prospective cross-sectional study was undertaken in the outpatient medical imaging department at a major public hospital in Australia, with institutional board approval. Adult outpatients undergoing a medical imaging procedure (CT, x-ray, MRI, ultrasound, angiography, or fluoroscopy) completed a preprocedural survey. Anxiety was measured by the short-form state scale of the six-item State-Trait Anxiety Inventory (STAI: Y-6). The number and percentage of participants who reported raised anxiety levels (defined as a STAI: Y-6 score ≥ 33.16) and their attribution of procedural-related anxiety or worry were calculated. Characteristics associated with raised anxiety were examined using multiple logistic regression analysis. RESULTS: Of the 548 (86%) patients who consented to participate, 488 (77%) completed all STAI: Y-6 items. Half of the participants (n = 240; 49%) experienced raised anxiety, and of these, 48% (n = 114) reported feeling most anxious or worried about the possible results. Female gender, imaging modality, medical condition, first time having the procedure, and lower patient-perceived health status were statistically significantly associated with raised anxiety levels. CONCLUSION: Raised anxiety is common before medical imaging procedures and is mostly attributed to the possible results. Providing increased psychological preparation, particularly to patients with circulatory conditions or neoplasms or those that do not know their medical condition, may help reduce preprocedural anxiety among these subgroups.

Unintentional silver intoxication following self-medication: an unusual case of corticobasal degeneration.

Silver toxicity is a rare condition. The most notable feature is a grey-blue discoloration of the skin, argyria, although harmful effects on the liver and kidney may be seen in severe cases. Neurological symptoms are an unusual consequence of silver toxicity. So far no effective treatment has been described for this metal overdose. We report the case of a 75-year-old man who had a history of self-medication with colloidal silver and presented with myoclonic seizures.
