The one-year infection risk among patients diagnosed with giant cell arteritis: use of antibiotics and hospitalisations.

OBJECTIVES: Patients with giant cell arteritis (GCA) primarily have their infections managed by primary care providers and hospitalisation is rarely necessary. Existing studies in GCA focus on infection-related hospitalisations only, whereas the use of antibiotic prescriptions is largely unknown. This study aims to examine the one-year overall infection risk among patients with GCA. METHODS: This nationwide observational cohort study included patients aged ≥50 years with a first-time GCA diagnosis in the Danish National Patient Registry (1996-2022). Patients with GCA were matched 1:10 by sex and date of birth with general population individuals and followed from date of diagnosis. Overall infections were defined as redeemed antibiotic prescriptions or infection-related hospitalisations. Utilising a pseudo-observation approach, we assessed 1-year cumulative incidence proportions (CIP), risk differences (RD), and relative risks (RR) of infections. RESULTS: The study included 17 773 incident patients with GCA and 177 730 reference individuals. Patients with GCA had a 1-year CIP of 52.4% (95% CI: 51.7-53.2) for overall infections and 17.6% (95% CI: 17.1-18.2) for infection-related hospitalisations. Compared with the reference cohort, patients with GCA had a RR of 1.40 (95% CI: 1.38-1.42) for overall infections and 2.71 (95% CI: 2.61-2.82) for infection-related hospitalisations. Additionally, higher cumulative glucocorticoid doses, advanced age (≥70 years), and higher comorbidity were associated with an increased risk of infections among patients with GCA. CONCLUSIONS: The use of antibiotic prescriptions and infection-related hospitalisations in the first year after a GCA diagnosis is high compared with the background population. The cumulative glucocorticoid dose is associated with the infection risk.

Low incidence of late-onset giant cell arteritis during the first year in patients with polymyalgia rheumatica-a repeated imaging study.

OBJECTIVE: The objective was to investigate the incidence of late-onset giant cell arteritis (GCA) within the first year in patients diagnosed with polymyalgia rheumatica (PMR). METHODS: In this prospective study, treatment-naïve individuals with a new clinical diagnosis of PMR and without GCA symptoms underwent baseline assessments, including vascular ultrasonography and 2-[18F]fluoro-2-deoxy-D-glucose positron emission tomography computed tomography (FDG-PET/CT). To prevent biased inclusion, rapid referral clinics were established for all patients suspected of PMR. Additionally, the patients underwent GCA monitoring during clinical visits at weeks 8 and 10, which involved vascular ultrasonography and FDG-PET/CT scans. After one year, a follow-up visit was performed to confirm the PMR diagnosis and perform vascular ultrasonography. RESULTS: A final PMR diagnosis was assigned to 62 patients, excluding 2 patients with concurrent subclinical GCA and PMR at baseline, corresponding to a baseline prevalence of subclinical GCA of 3%. During the one-year follow-up, two PMR patients developed late-onset GCA corresponding to an incidence rate of 32 per 1000 person-years. One patient developed GCA 14 weeks after the PMR diagnosis, exhibiting cranial symptoms and positive vascular ultrasonography. The other patient presented with subclinical large vessel GCA at the one-year visit detected with vascular ultrasonography and confirmed by FDG-PET/CT. CONCLUSION: This study is the first to demonstrate a low incidence rate of late-onset GCA in PMR patients within the first year, employing repeated imaging to exclude GCA at baseline and diagnose GCA during follow-up. Additionally, it provides evidence of a low prevalence of subclinical GCA across the entire PMR population. TRIAL REGISTRATION: ClinicalTrials.Gov, NCT04519580.

Improved Diagnostic Accuracy for Polymyalgia Rheumatica using FDG-PET/CT with Clinical Diagnosis or 2012 ACR/EULAR Classification Criteria.

PURPOSE: In routine care, clinicians may employ 2-[18F]fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET) computed tomography (CT) to validate their initial clinical diagnosis of polymyalgia rheumatica (PMR). Nevertheless, the diagnostic utility of combining FDG-PET/CT findings with clinical presentation has not been explored. Therefore, this study aimed to investigate whether the diagnostic accuracy for PMR could be enhanced by combining FDG-PET/CT findings with the clinical baseline diagnosis or the 2012 ACR/EULAR clinical classification criteria for PMR. METHODS: An investigation and a validation cohort were included from two countries, encompassing 66/27 and 36/21 PMR/non-PMR patients, respectively. The cohorts comprised treatment-naïve patients suspected of PMR, who initially received a clinical baseline diagnosis and underwent FDG-PET/CT scans. The FDG-PET/CT Leuven-score was applied to classify patients as either PMR or non-PMR and combined with the clinical baseline diagnosis. Final diagnoses were established through clinical follow-up after twelve or six months in the investigation and validation cohorts, respectively. RESULTS: In the investigation cohort, a clinical baseline diagnosis yielded a sensitivity/specificity of 94%/82%, compared with 78%/70% using the ACR/EULAR criteria. Combining the clinical baseline diagnosis with a positive Leuven-score showed a sensitivity/specificity of 80%/93%, compared with 80%/82% for an ACR/EULAR-Leuven-score. In the validation cohort, the baseline diagnosis revealed a sensitivity/specificity of 100%/91%, compared with 92%/76% using the ACR/EULAR criteria. Combining FDG-PET/CT with the baseline diagnosis demonstrated a sensitivity/specificity of 83%/95% compared with 89%/81% for the ACR/EULAR-Leuven-score. CONCLUSION: Combining FDG-PET/CT findings with the clinical baseline diagnosis or ACR/EULAR clinical classification criteria can improve the diagnostic specificity for PMR.

The effect of prednisolone and a short-term prednisolone discontinuation for the diagnostic accuracy of FDG-PET/CT in polymyalgia rheumatica-a prospective study of 101 patients.

PURPOSE: 2-[18F]Fluoro-2-deoxy-D-glucose (FDG)-positron emission tomography (PET)/computed tomography (CT) has been suggested as an imaging modality to diagnose polymyalgia rheumatica (PMR). However, the applicability of FDG-PET/CT remains unclear, especially following glucocorticoid administration. This study aimed to investigate the diagnostic accuracy of FDG-PET/CT before and during prednisolone treatment, as well as following short-term prednisolone discontinuation. METHODS: Treatment naïve suspected PMR patients were clinically diagnosed at baseline and subsequently had an FDG-PET/CT performed. Patients diagnosed with PMR were administered prednisolone following the first FDG-PET/CT and had a second FDG-PET/CT performed after 8 weeks of treatment. Subsequently, prednisolone was tapered with short-term discontinuation at week 9 followed by a third FDG-PET/CT at week 10. An FDG-PET/CT classification of PMR/non-PMR was applied, utilizing both the validated Leuven score and a dichotomous PMR score. The final diagnosis was based on clinical follow-up after 1 year. RESULTS: A total of 68 and 27 patients received a final clinical diagnosis of PMR or non-PMR. A baseline FDG-PET/CT classified the patients as having PMR with a sensitivity/specificity of 86%/63% (Leuven score) and 82%/70% (dichotomous score). Comparing the subgroup of non-PMR with inflammatory diseases to the PMR group demonstrated a specificity of 39%/54% (Leuven/dichotomous score). After 8 weeks of prednisolone treatment, the sensitivity of FDG-PET/CT decreased to 36%/41% (Leuven/dichotomous score), while a short-term prednisolone discontinuation increased the sensitivity to 66%/60%. CONCLUSION: FDG-PET/CT has limited diagnostic accuracy for differentiating PMR from other inflammatory diseases. If FDG-PET/CT is intended for diagnostic purposes, prednisolone should be discontinued to enhance diagnostic accuracy. TRIAL REGISTRATION: ClinicalTrials.gov (NCT04519580).

Home self-testing of complete blood counts in patients with breast cancer during chemotherapy: A proof-of-concept cohort study in e-oncology.

BACKGROUND: Before administration of myelosuppressive chemotherapy, complete blood counts (CBC) collected at the hospital/nursing stations are evaluated to avoid severe bone marrow suppression. This maintains disease fixation which often reduces their quality of life. This mixed-method study examined at home self-testing of CBC, the test quality, and the effects on patients' mental well-being. METHODS: Patients with breast cancer receiving chemotherapy were recruited and trained to perform capillary finger prick CBC testing at home using the HemoScreen Point-of-Care instrument and to upload the test results to the hospital's IT system subsequently. A venous reference CBC sample was taken and tested at the hospital on the day of self-testing. Semi-structured interviews with open-ended components were performed to investigate the user experience and the impact of self-testing on the patients' everyday lives. RESULTS: Thirty-nine patients completed the self-testing education using the HemoScreen instrument. Eight patients withdrew, while the remaining 31 patients performed 161 home tests (2-11 tests per patient) over a 4-month period. The test results compared well with the venous reference CBCs except for platelet counts (correlation coefficient 0.26). Qualitative interviews with nine of the 31 patients emphasized that the patients were comfortable using the self-testing instrument and becoming an active partner in their own treatment. INTERPRETATION: CBC self-testing at home produced clinically valid hemoglobin and white blood cell counts with the added benefit that the patients became active partners in their own treatment course, which was of great importance for the patients and increased their wellbeing.

EULAR recommendations for the use of imaging in large vessel vasculitis in clinical practice: 2023 update.

OBJECTIVES: To update the EULAR recommendations for the use of imaging modalities in primary large vessel vasculitis (LVV). METHODS: A systematic literature review update was performed to retrieve new evidence on ultrasound, MRI, CT and [18F]-fluorodeoxyglucose positron emission tomography (FDG-PET) for diagnosis, monitoring and outcome prediction in LVV. The task force consisted of 24 physicians, health professionals and patients from 14 countries. The recommendations were updated based on evidence and expert opinion, iterating until voting indicated consensus. The level of agreement was determined by anonymous votes. RESULTS: Three overarching principles and eight recommendations were agreed. Compared to the 2018 version, ultrasound is now recommended as first-line imaging test in all patients with suspected giant cell arteritis, and axillary arteries should be included in the standard examination. As an alternative to ultrasound, cranial and extracranial arteries can be examined by FDG-PET or MRI. For Takayasu arteritis, MRI is the preferred imaging modality; FDG-PET, CT or ultrasound are alternatives. Although imaging is not routinely recommended for follow-up, ultrasound, FDG-PET or MRI may be used for assessing vessel abnormalities in LVV patients with suspected relapse, particularly when laboratory markers of inflammation are unreliable. MR-angiography, CT-angiography or ultrasound may be used for long-term monitoring of structural damage, particularly at sites of preceding vascular inflammation. CONCLUSIONS: The 2023 EULAR recommendations provide up-to-date guidance for the role of imaging in the diagnosis and assessment of patients with LVV.

The provisional OMERACT ultrasonography score for giant cell arteritis.

OBJECTIVES: To develop an Outcome Measures in Rheumatology (OMERACT) ultrasonography score for monitoring disease activity in giant cell arteritis (GCA) and evaluate its metric properties. METHODS: The OMERACT Instrument Selection Algorithm was followed. Forty-nine members of the OMERACT ultrasonography large vessel vasculitis working group were invited to seven Delphi rounds. An online reliability exercise was conducted using images of bilateral common temporal arteries, parietal and frontal branches as well as axillary arteries from 16 patients with GCA and 7 controls. Sensitivity to change and convergent construct validity were tested using data from a prospective cohort of patients with new GCA in which ultrasound-based intima-media thickness (IMT) measurements were conducted at weeks 1, 3, 6, 12 and 24. RESULTS: Agreement was obtained (92.7%) for the OMERACT GCA Ultrasonography Score (OGUS), calculated as follows: sum of IMT measured in every segment divided by the rounded cut-off values of IMTs in each segment. The resulting value is then divided by the number of segments available. Thirty-five members conducted the reliability exercise, the interrater intraclass correlation coefficient (ICC) for the OGUS was 0.72-0.84 and the median intrareader ICC was 0.91. The prospective cohort consisted of 52 patients. Sensitivity to change between baseline and each follow-up visit up to week 24 yielded standardised mean differences from -1.19 to -2.16, corresponding to large and very large magnitudes of change, respectively. OGUS correlated moderately with erythrocyte sedimentation rate, C reactive protein and Birmingham Vasculitis Activity Score (corrcoeff 0.37-0.48). CONCLUSION: We developed a provisional OGUS for potential use in clinical trials.

Ultrasonography in the assessment of disease activity in cranial and large-vessel giant cell arteritis: a prospective follow-up study.

OBJECTIVES: We evaluated sensitivity to change and discriminative abilities of vascular US scores in disease monitoring in the follow-up of a prospective cohort of new-onset cranial and large-vessel (LV) GCA patients. METHODS: Baseline and follow-up (8 weeks, 24 weeks and 15 months) US of temporal arteries (TA), carotid and axillary arteries (LV) included assessment of halo and measurement of the intima media complex (IMC). Max IMC, max halo IMC, sum IMC, sum halo IMC, mean IMC, halo count and the Southend halo score were calculated. The provisional OMERACT US score, OGUS, was obtained, taking the average of temporal arteries and axillary arteries IMCs divided by their normal cut-off values. RESULTS: Baseline US was positive in 44/47 patients (72% TA, 72% LV). Sensitivity to change of all composite US scores containing TAs was evident by week 8 onward. LVs responded poorly and new axillary US lesions emerged in six patients despite clinical remission. The OGUS showed a large magnitude of change and is considered the score least prone to potential bias. All TA-based US scores showed moderate-strong correlation with disease activity markers. OGUS, TA halo count, Southend TA halo score, TA sum IMC and TA mean IMC showed potential to discriminate remission and relapse with area under the curve ≥0.8. CONCLUSIONS: The OGUS is suggested as an outcome measurement for the assessment of treatment response in clinical trials. The abilities of US scores to discriminate remission and relapse are encouraging and should be further explored.

An international survey of current management practices for polymyalgia rheumatica by general practitioners and rheumatologists.

OBJECTIVES: To explore current management practices for PMR by general practitioners (GPs) and rheumatologists including implications for clinical trial recruitment. METHODS: An English language questionnaire was constructed by a working group of rheumatologists and GPs from six countries. The questionnaire focused on: 1: Respondent characteristics; 2: Referral practices; 3: Treatment with glucocorticoids; 4: Diagnostics; 5: Comorbidities; and 6: Barriers to research. The questionnaire was distributed to rheumatologists and GPs worldwide via members of the International PMR/Giant Cell Arteritis Study Group. RESULTS: In total, 394 GPs and 937 rheumatologists responded to the survey. GPs referred a median of 25% of their suspected PMR patients for diagnosis and 50% of these were returned to their GP for management. In general, 39% of rheumatologists evaluated patients with suspected PMR >2 weeks after referral, and a median of 50% of patients had started prednisolone before rheumatologist evaluation. Direct comparison of initial treatment showed that the percentage prescribing >25 mg prednisolone daily for patients was 30% for GPs and 12% for rheumatologists. Diagnostic imaging was rarely used. More than half (56%) of rheumatologists experienced difficulties recruiting people with PMR to clinical trials. CONCLUSION: This large international survey indicates that a large proportion of people with PMR are not referred for diagnosis, and that the proportion of treatment-naive patients declined with increasing time from referral to assessment. Strategies are needed to change referral and management of people with PMR, to improve clinical practice and facilitate recruitment to clinical trials.

Mental well-being and patient activation during the first eight months of the COVID-19 pandemic in Denmark - a cohort study among 710 Danish adults with chronic conditions.

BACKGROUND: COVID-19 has highlighted the importance of patient activation in managing chronic conditions and promoting resilience during times of crisis. Patient activation refers to an individual's knowledge, skills, and confidence in managing their own health and healthcare. Previous research has shown that people with higher levels of patient activation are better prepared to navigate the challenges of chronic illness and are more likely to engage in healthy behaviors. However, the impact of patient activation on COVID-19-related concerns and mental well-being among people with chronic conditions during the pandemic remains unclear. This study aims to investigate the possible role of patient activation in shaping COVID-19-related concerns and to describe changes in mental well-being among Danish adults with one or more chronic conditions during the early months of the pandemic. METHODS: Danish adults with chronic conditions (e.g. diabetes, coronary heart disease, obstructive pulmonary lung disease, cancer) who had participated in a municipal health education program prior to the COVID-19 outbreak were asked to participate in this prospective questionnaire study in May 2020 and November 2020. Sociodemographic (sex, age, living status, educational attainment, employment status) and disease-related information (diagnosis, one or more chronic conditions) along with the Patient Activation Measure were collected before the outbreak and were obtained from a clinical database used for monitoring and evaluation of municipal health education programs. In contrast, the two questionnaires collected six months apart consisted of single items related to concerns about COVID-19 and the WHO-5 well-being index. RESULTS: A total of 710 people with chronic conditions (mean age 60.9 years; 55.8% female) participated at both time points. In bivariate analyses, patient activation was associated with COVID-19-related concern and well-being. At follow-up, participants experienced a significant decrease in well-being. The decrease was associated with poorer well-being measured six months earlier, a greater perception that it had become more challenging to take care of one's health due to the pandemic, and finally, feeling lonely. The association between patient activation and well-being ceased to be significant in the multivariate regression model. CONCLUSIONS: A considerable proportion of people with chronic conditions participating in this study have been mentally burdened during COVID-19. Although lower levels of patient activation were associated with greater COVID-19-related concerns, it did not have a significant impact on mental well-being over time.

Nurses' perspectives on challenges and facilitators when implementing a self-management support intervention as an everyday healthcare practice: A qualitative study.

AIM: To explore registered nurses' perspectives on challenges and facilitators to implementing a telephone-based self-management support (SMS) intervention (Proactive Health Support) as an everyday healthcare practice, during the early stages of implementation. DESIGN: Data were collected using a qualitative research design involving focus-group interviews and participant observations. METHODS: We conducted participant observation following nine nurses and four focus group interviews with 14 nurses. Data were analysed using thematic analyses. RESULTS: Proactive Health Support was implemented in units organized independently of the existing organizational units within healthcare services. This independent organization, along with the intervention's generic (non-disease specific) design, empowered nurses to become autonomous practitioners capable of prioritizing the operationalization of SMS as an everyday healthcare practice. However, unlearning already embedded medical practices and establishing new nursing roles necessary to accommodate the intervention in practice was experienced a challenge. Education and supervision were identified as valuable tools for successful implementation. CONCLUSION: Our study highlights the significance of organizational context and autonomy in successful SMS implementation. Balancing external factors like organizational context, priority and time is vital, but navigating the internal shift in professional practice is equally crucial. Role transition processes can constitute challenges demanding accommodation. IMPLICATIONS FOR THE PROFESSION: From a nursing perspective, this study highlights that practising SMS requires substantial training and education. Generic SMS interventions can introduce higher levels of contingency due to their versatile nature. Thus, equipping nurses with competencies that enable them to navigate this unpredictability flexibly is crucial. IMPACT: Policymakers and administrators should allocate resources and support implementation processes in ways that accommodate both internal and external conditions to facilitate nurses in delivering effective SMS. REPORTING METHOD: This study adheres to the SRQR guideline. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

COVID-19 as moral breakdown: Entangled ethical demands experienced by hospital-based nurses in the early onset of the pandemic.

2020 saw the rapid onset of a global pandemic caused by the SARS-CoV-2 virus. For healthcare systems worldwide, the pandemic called upon quick organization ensuring treatment and containment measures for the new virus disease. Nurses were seen as constituting a vital instrumental professional component in this study. Due to the pandemic's unpredictable and potentially dangerous nature, nurses have faced unprecedented risks and challenges. Based on interviews and free text comment from a survey, this study explores how ethical challenges related to "being a nurse" during the COVID-19 pandemic was experienced and understood by Danish hospital-based nurses. Departing from anthropologist Jarett Zigon's notion of moral breakdown, the study demonstrates how the rapid onset of the pandemic constitutes a moral breakdown raising ethical demands for nurses. Analytically we identify three different ethical demands experienced by the nurses. These ethical demands are Nursing and societal ethical demands, Nursing and personal ethical demands, and Nursing and conflicting ethical demands. These demands represent not only very different understandings of ethical demands but also different understandings of ethical acts that are seen as necessary to respond to these demands.

All-cause and cause-specific mortality in patients with giant cell arteritis: a nationwide, population-based cohort study.

OBJECTIVES: To investigate whether GCA is associated with increased all-cause and cause-specific mortality. METHODS: A nationwide, population-based cohort study in Denmark using medical and administrative registries. GCA cases were defined as patients aged ≥50 years from 1996-2018 with a first-time discharge diagnosis of GCA and ≥3 prescriptions for prednisolone within 6 months following diagnosis. Each GCA patient was matched based on age, sex and calendar time to 10 persons without a history of GCA. Index date was the date for the third prednisolone prescription. We used a pseudo-observation approach to calculate all-cause and cause-specific mortality, adjusted risk differences (RDs) and relative risks (RRs). RESULTS: We included 9908 GCA patients and 98 204 persons from the general population. The median time for GCA patients to redeem the third prednisolone prescription was 74 days [interquartile range (IQR: 49-106)]. Among GCA patients, the overall mortality was 6.4% (95% CI: 5.9, 6.9) 1 year after index date and 45% (95% CI: 44, 47) after 10 years. Compared with the reference cohort, adjusted RDs and RRs of deaths in the GCA cohort were 2.2% (95% CI: 1.7, 2.7) and 1.49 (95% CI: 1.36, 1.64) after 1 year, and 2.1% (95% CI: 1.0, 3.3) and 1.03 (95% CI: 1.00, 1.05) 10 years after index date. GCA patients had a higher risk of death due to infectious, endocrine, cardiovascular and gastrointestinal diseases. CONCLUSIONS: GCA is associated with increased all-cause mortality, particularly within the first year following the diagnosis. Cause-specific mortality indicates that mortality in GCA may in part be due to glucocorticoid-related complications.

Increased risk of thoracic aortic complications among patients with giant cell arteritis: a nationwide, population-based cohort study.

OBJECTIVE: To assess the risk of aortic aneurysms (AA), aortic dissections (AD) and peripheral arterial disease (PAD) among patients with GCA. METHODS: In this nationwide, population-based cohort study using Danish national health registries, we identified all incident GCA patients ≥50 years between 1996 and 2018 who redeemed three or more prescriptions for prednisolone. Index date was the date of redeeming the third prednisolone prescription. Case definition robustness was checked through sensitivity analysis. We included general population referents matched 1:10 by age, sex and calendar time. Using a pseudo-observation approach, we calculated 5-, 10- and 15-year cumulative incidence proportions (CIP) and relative risks (RR) of AA, AD and PAD with death as a competing risk. RESULTS: We included 9908 GCA patients and 98 204 referents. The 15-year CIP of thoracic AA, abdominal AA, AD and PAD in the GCA cohort were 1.9% (95% CI 1.5, 2.2), 1.8% (1.4-2.2), 1.0% (0.7-1.2) and 4.8% (4.2-5.3). Compared with the referents, the 15-year RR were 11.2 (7.41-16.9) for thoracic AA, 6.86 (4.13-11.4) for AD, 1.04 (0.83-1.32) for abdominal AA and 1.53 (1.35-1.74) for PAD. Among GCA patients, female sex, age below 70 years and positive temporal artery findings were risk factors for developing thoracic AA. The median time to thoracic AA was 7.5 years (interquartile range 4.4-11.2) with a number needed to be screened of 250 (167-333), 91 (71-111) and 53 (45-67) after 5, 10 and 15 years. CONCLUSION: Patients with GCA have a markedly increased risk of developing thoracic AA and AD, but no increased risk of abdominal AA.

Changes in distress and turnover intentions among hospital-based nurses working during the first 8 months of the COVID-19 pandemic in Denmark: A prospective questionnaire study.

AIM: To describe changes in distress among Danish hospital-based nurses during the early month of the COVID-19 pandemic and to examine predictors of distress and turnover intentions. BACKGROUND: Outbreak of infectious diseases such as the COVID-19 pandemic can increase the likelihood that health professionals suffer from poor mental health even after the outbreak. METHODS: A prospective study among 426 Danish hospital-based nurses during the early month of the pandemic. Participants completed self-administered questionnaires regarding mental health and COVID-19 worries, as well as turnover intentions. RESULTS: Nurses with brief work experience reported higher increase in distress. Feeling unsafe at work, having low trust in management and being anxious for relatives were associated with increased distress. Finally, feeling unsafe at work, being anxious for relatives and having low trust in management were predictors of intention to change job. CONCLUSION: This study suggests that the subjective experiences of uncertainty in work during the COVID-19 pandemic have more impact on nurses' distress than COVID-19 related conditions at hospitals. Finally, the study provides empirical support for the association between COVID-19-related worries and turnover intentions. IMPLICATION FOR NURSING MANAGEMENT: Knowledge of risk factors for psychological distress as well as predictors of turnover intention is necessary and may provide nurses and health-care systems with the ability to respond better against future pandemics and to retain nurses in the organization and in the profession.

Diagnosing giant cell arteritis: a comprehensive practical guide for the practicing rheumatologist.

GCA is the most common large vessel vasculitis in the elderly population. In recent years, advanced imaging has changed the way GCA can be diagnosed in many locations. The GCA fast-track clinic approach combined with US examination allows prompt treatment and diagnosis with high certainty. Fast-track clinics have been shown to improve prognosis while being cost effective. However, all diagnostic modalities are highly operator dependent, and in many locations expertise in advanced imaging may not be available. In this paper, we review the current evidence on GCA diagnostics and propose a simple algorithm for diagnosing GCA for use by rheumatologists not working in specialist centres.

Effect of patient-reported outcomes as a dialogue-based tool in cancer consultations on patient self-management and health-related quality of life: a clinical, controlled trial.

BACKGROUND: With increased survival among patients with metastatic melanoma and limited time with health care providers, patients are expected to assume a more active role in managing their treatment and care. Activated patients have the knowledge, skills, and confidence to make effective solutions to self-manage health. The use of patient-reported outcomes (PRO) could have the potential to enhance patient activation. However, PRO-based interventions that facilitate an activation in patients with metastatic melanoma are lacking and warranted. MATERIAL AND METHODS: In this prospective non-randomized controlled, clinical trial, patients with metastatic melanoma were assigned to either the intervention (systematic feedback and discussion of PRO during consultation) given at one hospital or the control group (treatment as usual) if they received treatment from two other hospitals in Denmark. The primary outcome was the patient activation measure (PAM), which reflects self-management. Secondary outcomes were health-related quality of life (HRQoL), self-efficacy, and Patient-Physician interaction. Outcomes were measured at baseline, and after 3, 6, and 12 months. The analysis of the effect from baseline to 12 months employed mixed-effects modeling. RESULTS: Between 2017 and 2019, patients were allocated to either the intervention group (n = 137) or the control group (n = 142). We found no significant difference in the course of patient activation between the two groups over time. The course of HRQoL was statistically significantly improved by the intervention compared to the control group. Especially, females in the intervention group performed better than males. The other secondary outcomes were not improved by the intervention. CONCLUSION: The intervention did not improve knowledge, skills, and confidence for self-management for patients with metastatic melanoma. Neither did it improve coping self-efficacy nor perceived efficacy in Patient-Physician interaction. However, the results suggest that the intervention can have a significant impact on HRQoL and in particular social and emotional well-being among the females.

Family involvement and patient-experienced improvement and satisfaction with care: a nationwide cross-sectional study in Danish psychiatric hospitals.

BACKGROUND: Randomised controlled trials suggest that family therapy has a positive effect on the course of depression, schizophrenia and anorexia nervosa. However, it is largely unknown whether a positive link also exists between caregiver involvement and patient outcome in everyday psychiatric hospital care, using information reported directly from patients, i.e. patient-reported experience measures (PREM), and their caregivers. The objective of this study is to examine whether caregiver-reported involvement is associated with PREM regarding patient improvement and overall satisfaction with care. METHODS: Using data from the National Survey of Psychiatric Patient Experiences 2018, we conducted a nationwide cross-sectional study in Danish psychiatric hospitals including patients and their caregivers who had been in contact with the hospital (n = 940 patients, n = 1008 caregivers). A unique patient identifier on the two distinct questionnaires for the patient and their caregiver enabled unambiguous linkage of data. In relation to PREM, five aspects of caregiver involvement were analysed using logistic regression with adjustment for patient age, sex and diagnosis. RESULTS: We consistently find that high caregiver-reported involvement is statistically significantly associated with high patient-reported improvement and overall satisfaction with care with odds ratios (OR) ranging from 1.69 (95% confidence interval (CI) 0.95-2.99) to 4.09 (95% CI 2.48-6.76). This applies to the following aspects of caregiver-reported involvement: support for the patient-caregiver relationship, caregiver information, consideration for caregiver experiences and the involvement of caregivers in decision making. No statistically significant association is observed regarding whether caregivers talk to the staff about their expectations for the hospital contact. CONCLUSION: This nationwide study implies that caregiver involvement focusing on the patient-caregiver relationship is positively associated with patient improvement and overall satisfaction with care in everyday psychiatric hospital care.

Diagnostic accuracy of ultrasound for detecting large-vessel giant cell arteritis using FDG PET/CT as the reference.

OBJECTIVES: The diagnostic accuracy of axillary artery US in the diagnosis of large-vessel (LV)-GCA using 18F-fluorodeoxyglucose (FDG) PET/CT as reference standard was prospectively evaluated in GCA-suspected patients. As an exploratory analysis, the diagnostic accuracy of cranial artery FDG PET/CT was evaluated. METHODS: Briefly, the inclusion criteria were age ≥50 years, raised inflammatory markers and potential GCA symptoms. Patients in immunosuppressive therapy or with a previous diagnosis of GCA or PMR were excluded. Examinations were performed pre-treatment. LV-GCA reference diagnosis was a clinical diagnosis of GCA and PET-proven LV inflammation. GCA patients fulfilling ACR criteria were considered as cranial-GCA (c-GCA). Patients without GCA were considered controls. Receiver operating characteristic curve analysis of the US-measured axillary intima-media thickness was performed. FDG uptake in temporal, maxillary and vertebral arteries was also assessed. RESULTS: Forty-six patients were diagnosed with LV-GCA, 10 with isolated c-GCA, and in 34 patients GCA was dismissed. Axillary US yielded a sensitivity of 76% and a specificity of 100% for LV-GCA. An axillary intima-media thickness cut-off of 1.0 mm yielded a sensitivity of 74% and a specificity of 92%. Adding LV US to temporal assessment increased sensitivity from 71% to 97% (all GCA patients). Cranial artery PET showed a diagnostic sensitivity of 78% and specificity of 100% for c-GCA. CONCLUSION: Axillary artery US shows high accuracy for the LV-GCA diagnosis. Building upon the recent EULAR recommendations, we propose a diagnostic algorithm with US as the first-line confirmatory test, not only in c-GCA-suspected patients, but in all patients suspected of GCA.

Simple dichotomous assessment of cranial artery inflammation by conventional 18F-FDG PET/CT shows high accuracy for the diagnosis of giant cell arteritis: a case-control study.

PURPOSE: To estimate the diagnostic accuracy of conventional 18F-FDG PET/CT of cranial arteries in the diagnosis of giant cell arteritis (GCA). METHODS: The study was a retrospective case-control study. The reference diagnosis was fulfillment of the 1990 ACR criteria for GCA. All patients had new-onset GCA. Conventional 18F-FDG PET/CT was performed before glucocorticoid treatment. Controls were age- and sex-matched patients with a previous history of malignant melanoma (MM) undergoing surveillance PET/CT >6 months after MM resection. PET images were evenly cropped to include only head and neck and were assessed in random order by four nuclear medicine physicians blinded to reference diagnosis. Temporal (TA), maxillary (MA) and vertebral (VA) arteries were visually rated for 18F-FDG uptake. Interreader agreement was evaluated by Fleiss kappa. RESULTS: A total of 44 patients and 44 controls were identified. In both groups, the mean age was 69 years (p = 0.45) and 25/44 were women. 35/41 GCA patients were temporal artery biopsy positive (TAB). Considering only FDG uptake in TA and/or MA, diagnostic sensitivity and specificity was 64 and 100%. Including VA, sensitivity increased to 82% and specificity remained 100%. Interreader agreement was 91% and Fleiss kappa 0.82 for the PET diagnosis based on the cranial arteries. CONCLUSION: Conventional 18F-FDG PET/CT is an accurate and reliable tool to diagnose cranial arteritis in glucocorticoid-naïve GCA patients. The high diagnostic specificity suggests that TAB can be omitted in patients with 18F-FDG uptake in cranial arteries. 18F-FDG PET/CT performed in patients with suspected vasculitis should always include the head and neck.
