RESUMO
BACKGROUND: The aim of the study was to measure empathy in healthcare professionals in Singapore and to compare the scores between the different professions: doctors, nurses, and allied health professionals. METHODS: An online survey questionnaire was conducted using the Jefferson Scale of Empathy (JSE) from July 2019 to January 2020. The total JSE score was calculated and compared among the different groups. Multiple linear regression was performed to assess predictors of total empathy scores for groups with statistically lower scores. RESULTS: The survey was completed by 4,188 healthcare professionals (doctors (n=569, 13.6%), nurses (n=3032, 72.4%), and allied health professionals (n=587, 14.0%)) out of the 9,348-strong survey population, with a response rate of 44.8%. The study revealed a mean empathy score (SD) of 103.6 (15.6) for the cohort. The mean empathy score (SD) was 112.3 (14.7), 101.3 (15.2), and 107.0 (15.0), respectively for doctors, nurses, and allied health professionals. These were statistically significantly different among the groups (p< 0.0001), with nurses scoring significantly lower than either doctors (p< 0.0001) or allied health professionals (p< 0.0001). Multiple linear regression showed that age < 30 years old, male gender, Malay ethnicity, and working in a hospital setting were associated with significantly lower empathy scores in the nursing group. CONCLUSION: Nurses in Singapore had significantly lower empathy scores compared to doctors and allied health professionals. Further research on the underlying causes should be undertaken and measures to improve empathy among Singapore nursing staff should be explored and implemented.
RESUMO
Background: The Coronavirus Disease 2019 (COVID-19) pandemic has had a significant impact on all walks of life, in particular, environmental services workers in healthcare settings had higher workload, increased stress and greater susceptibility to COVID-19 infections during the pandemic. Despite extensive literature describing the impact of the pandemic on healthcare workers such as doctors and nurses, studies on the lived experiences of environmental services workers in healthcare settings are sparse and none has been conducted in the Asian context. This qualitative study thus aimed to examine the experiences of those who worked for a year of the COVID-19 pandemic. Methods: A purposive sample of environmental services workers was recruited from a major tertiary hospital in Singapore. Semi-structured interviews were conducted in-person, lasting around 30min, and included open-ended questions pertaining to five main domains: work experiences during COVID-19, training and education needs, resource and supplies availability, communication with management and other healthcare staff, and perceived stressors and support. These domains were identified based on team discussions and literature review. The interviews were recorded and transcribed for thematic analysis, as guided by Braun and Clarke. Results: A total of 12 environmental services workers were interviewed. After the first seven interviews, no new themes emerged but an additional five interviews were done to ensure data saturation. The analysis yielded three main themes and nine subthemes, including (1) practical and health concerns, (2) coping and resilience, and (3) occupational adaptations during the pandemic. Many expressed confidence in the preventive efficacy of proper PPE, infection control practice and COVID-19 vaccination in protecting them against COVID-19 and severe illness. Having prior experience with infectious disease outbreaks and previous training in infection control and prevention appeared to be useful as well for these workers. Despite the various challenges presented by the pandemic, they could still find meaning in their everyday work by positively impacting the wellbeing of patients and other healthcare workers in the hospital. Conclusion: Besides uncovering the concerns shared by these workers, we identified helpful coping strategies, resilience factors and certain occupational adaptations, which have implications for future pandemic planning and readiness.

INTRODUCTION: Improved sleep hygiene is postulated to be protective against burnout. Previous studies assessing a potential association between poor sleep quality and burnout showed incongruent results. OBJECTIVE: To investigate the relationship between sleep quality and burnout. DESIGN: Setting and Participants: A survey was conducted in a large health care cluster in Singapore and included health care staff from different professions (N = 4777). The Maslach Burnout Inventory - Human Services Survey was used to measure burnout across 3 sub-scales: Emotional Exhaustion, Depersonalization and Personal Accomplishment, while the Pittsburgh Sleep Quality Index (PSQI) was used to gauge the participants' sleep quality. Multi-variable general linear model ANOVA was used for correlation analysis. RESULTS: There is a strong correlation between sleep quality and all 3 burnout sub-scales. PSQI is associated with Emotional Exhaustion (F value = 90.65, P-value <.0001), Depersonalization (F value = 49.46, P-value <.0001) and Personal Accomplishment (F value = 12.29, P-value <.0001). PSQI shows a significant linear upward trend with Emotional Exhaustion (linear contrast = 957.06, P-value <.0001) and with Depersonalization (linear contrast = 521.92, P-value <.0001). With Personal Accomplishment, PSQI shows a significant linear downward trend (linear contrast = 123.61, P-value <.0001). CONCLUSION: Poor sleep quality is progressively and linearly associated with burnout and its 3 sub-scales. Future studies that evaluate interventions which improve sleep quality among health care workers may be useful in reducing burnout and improving patient care.

Singapore managed the COVID-19 pandemic in the past three years and gleaned valuable lessons on patient management when the public healthcare system was inundated with COVID-19 patients. There were several initiatives, which included setting up of community treatment facilities to help hospitals manage in-patient loads that did not require acute monitoring, leveraging telemedicine, and developing heuristics to sort patients based on their clinical disposition to various care pathways and to effectively manage patients of different medical needs. These initiatives were implemented in the second year of the epidemic in 2021 and did not include the dormitory-based migrant workers and migrant workers in the construction, maritime and production sectors who were under the care of the Assurance, Care and Engagement Group (ACE) in the Ministry of Manpower that had its own set of treatment management measures. The different care pathways ensured that patients received appropriate levels of care and allowed healthcare facilities to focus on more acute cases. In 2022 alone, 23,159 patients were discharged from community treatment facilities against the background of 1.9 million COVID-19 patients. These initiatives would not be possible without the oversight of an advisory board comprising senior leadership from the healthcare clusters and the Ministry of Health to align clinical governance with medical policies, and prompt and immense support from medical specialist panels. The strong public-private partnership forged in the process was instrumental in the successful operation of community facilities and implementation of patient care protocols, coupled with harnessing information technology and leveraging on emerging data to refine care protocols.

INTRODUCTION: The aim was to study the prevalence of burnout among various groups of healthcare professionals in Singapore. METHODS: An anonymous online survey questionnaire was conducted using the Maslach Burnout Inventory - Human Services to measure three categories of burnout: emotional exhaustion (EE), depersonalisation (DP) and personal accomplishment (PA) from July 2019 to January 2020 in a healthcare cluster in Singapore. RESULTS: The survey was completed by 6,048 healthcare professionals out of a target survey population of 15,000 (response rate 40.3%). The study revealed 37.8% of respondents had high EE score ≥27, 29.7% of respondents had high DP score ≥10, and 55.3% of respondents had low PA score ≤33. Respondents with either high EE score or high DP score constituted 43.9% (n=2,654). The Allied Health group had the highest mean EE score, which was significantly higher than those of Medical, Nursing and Non-clinical groups (P<0.05). The Medical group had the highest mean DP score and this was significantly higher than the Nursing, Allied Health and Non-clinical groups (P<0.05). The Non-clinical group had the lowest PA, which was significantly lower than the Medical, Nursing and Allied Health groups (P<0.005). CONCLUSION: There was high prevalence of burnout among healthcare professionals in Singapore, especially the allied health professionals. There were significant differences in the 3 categories of burnout (EE, DP and PA) among the different groups of healthcare professionals. There is an urgent need to address the high burnout rate.

BACKGROUND: There is a need to reexamine Singapore's medical school curricula in light of the increasing digitalization of healthcare. Notwithstanding Singapore's digital competitiveness, there is a perceived gap in preparing its medical students for the digital age. Furthermore, limited research has evaluated the extent to which skills in using digital technologies should be taught to medical students in Asian medical schools to prepare them for future clinical practice- a gap that is filled by this study. Using Singapore as a case study, it explores the views of some local clinical educators and teachers towards the need to impart skills in digital technologies to medical students. It also offers recommendations on ways to balance the clinicians' concerns about these technologies with the digital competencies needed for clinical practice. METHODS: Findings were drawn from individual interviews with 33 clinical educators and teachers from Singapore's public and private healthcare sectors. They were recruited using purposive sampling. Data were interpreted using qualitative thematic analysis. RESULTS: Participants included vice deans of education from all three local medical schools and senior consultants from a wide variety of disciplines. Overall, they acknowledged two benefits of equipping students with skills in digital technologies including promoting the culture of innovation and improving work efficiency. However, they also highlighted four main concerns of imparting these skills: (i) erosion of basic clinical skills, (ii) neglect of a generalist approach to healthcare characterized by holistic management of patients, inter-professional collaboration, and commitment to breadth of practice within each specialty, (iii) rapid pace of technological advances, and (iv) de-personalisation by technology. CONCLUSIONS: The findings show that medical students in Singapore would benefit from a curriculum that teaches them to use digital technologies alongside core clinical skills.

OBJECTIVE: To determine the prevalence, factors associated with and patterns of concomitant Chinese medicine (CM) with Western treatment use among patients with rheumatoid arthritis (RA) in a tertiary referral centre (Singapore General Hospital) in Singapore. METHODS: We conducted a cross-sectional interviewer-administered survey of a consecutive sample of patients with RA in Singapore General Hospital centre regarding their CM use including data on patient demographics, disease characteristics, concomitant use of CM and reasons, concerns and disclosure patterns from March to August 2015. Univariate and multivariate logistic regression analyses were performed to determine the associations of CM use. RESULTS: Prevalence of CM use among the 258 patients surveyed (male: female 42: 216; Chinese: Malay: Indian 191: 29: 34; mean age: 61 years; mean duration of RA: 10 years) was 46.1% (119/258). On multivariate analysis, Chinese ethnicity (OR, 95% CI: 4.11, 1.49-11.36), Chinese speakers (OR, 95% CI: 2.35, 1.03-5.54), middle-income group (OR, 95% CI: 2.53, 1.01-6.31) and greater learned helplessness (OR, 95% CI: 1.13, 1.04-1.22) were significantly associated with CM use. More CM users disclosed their CM use to CM physicians (87.3%, 96/110), sought advice from them on treatment interactions (59.4%, 57/96) and how best to combine treatments (49.0%, 47/96) than did so with rheumatologists (42.0%, 50/119; 40.0%, 20/50; and 42.0%, 21/50, respectively). Forty-two percentage (29/69) of patients who concealed CM use from rheumatologists because their rheumatologists did not specifically enquire about CM use. CONCLUSIONS: Concomitant CM use among patients with RA treated in a tertiary referral centre in Singapore is high but voluntary disclosure is low. The associations identified can help doctors identify and enquire about CM use, minimizing potential adverse interactions.

BACKGROUND: Conventional therapy may be inadequate for many patients with axial spondyloarthritis (axSpA). Traditional Chinese medicine (TCM) may be a viable alternative, but its effectiveness for axSpA is unknown. We are currently conducting a pragmatic randomised controlled trial (RCT) to investigate the effectiveness of a TCM collaborative model of care (TCMCMC), which combines usual rheumatologic care with acupuncture for patients with axSpA. This nested qualitative sub-study aims to identify facilitators of and barriers to the implementation of the TCMCMC. METHODS: We conducted individual in-depth interviews with participants who had completed the acupuncture regimen to elicit opinions on the facilitators of and barriers to the implementation of the TCMCMC. The interviews were transcribed and analysed using thematic analysis. RESULTS: Twelve participants were included, with data saturation occurring after 10 interviews. The analysis revealed both a number of important 'facilitators' and 'barriers'. Facilitators to the implementation of the TCMCMC included effectiveness of TCM to relieve symptoms, inadequacy of conventional treatment and positive social perceptions of TCM. Barriers included scepticism towards TCM, inability of TCM to provide instant relief, needle-related discomfort, variable effectiveness of TCM influenced by physicians' skills and experience and the high cost of TCM. Recommendations to overcome barriers included further patient education about TCM. CONCLUSION: Policymakers should take into account the various feasibility factors identified in this study when developing and implementing a TCMCMC. TRIAL REGISTRATION NUMBER: NCT03420404 (ClinicalTrials.gov).

BACKGROUND: Axial spondyloarthritis (AxSpA) is a chronic disease which results in fatigue, pain, and reduced quality of life (QoL). Traditional Chinese medicine (TCM), especially acupuncture, has shown promise in managing pain. Although a TCM collaborative model of care (TCMCMC) has been studied in cancer, there are no randomized controlled trials investigating TCM in AxSpA. Therefore, we will conduct a pragmatic trial to determine the clinical effectiveness, safety, and cost-effectiveness of TCMCMC for patients with AxSpA. We define TCMCMC as standard TCM history taking and physical examination, acupuncture, and TCM non-pharmacological advice and communications with rheumatologists in addition to usual rheumatologic care. The purpose of this paper is to describe the rationale for and methodology of this trial. METHODS/DESIGN: This pragmatic randomized controlled trial will recruit 160 patients who are diagnosed with AxSpA and have inadequate response to non-steroidal anti-inflammatory drugs (NSAIDs). Simple randomization to usual rheumatologic care or the intervention (TCMCMC) with a 1:1 allocation ratio will be used. Ten 30-min acupuncture sessions will be provided to patients assigned to the TCMCMC arm. All participants will continue to receive usual rheumatologic care. The primary endpoint - spinal pain - will be evaluated at week 6. Secondary endpoints include clinical, quality of life, and economic outcome measures. Patients will be followed up for up to 52 weeks, and adverse events will be documented. DISCUSSION: This trial may provide evidence regarding the clinical effectiveness, safety, and cost-effectiveness of a TCMCMC for patients with AxSpA. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03420404 . Registered on 14 February 2018.

INTRODUCTION: Pneumonia is associated with considerable mortality. However, there is limited information on age-specific prognostic factors for death from pneumonia. METHODS: Patients hospitalised with a diagnosis of pneumonia through the emergency department were stratified into three age groups: 18-64 years, 65-84 years and ≥ 85 years. Multivariate logistic regression and receiver operating characteristic curve analyses were conducted to evaluate prognostic factors for mortality and the performance of pneumonia severity scoring tools for mortality prediction. RESULTS: A total of 1,902 patients were enrolled (18-64 years: 614 [32.3%]; 65-84 years: 944 [49.6%]; ≥ 85 years: 344 [18.1%]). Mortality rates increased with age (18-64 years: 7.3%; 65-84 years: 16.1%; ≥ 85 years: 29.7%; p < 0.001). Malignancy and tachycardia were prognostic of mortality among patients aged 18-64 years. Male gender, malignancy, congestive heart failure and eight other parameters reflecting acute disease severity were associated with mortality among patients aged 65-84 years. For patients aged ≥ 85 years, altered mental status, tachycardia, blood urea nitrogen, hypoxaemia, arterial pH and pleural effusion were significantly predictive of mortality. The Pneumonia Severity Index (PSI) was more sensitive than CURB-65 (confusion, uraemia, respiratory rate ≥ 30 per minute, low blood pressure, age ≥ 65 years) for mortality prediction across all age groups. CONCLUSION: The predictive effect of prognostic factors for mortality varied among patients with pneumonia from the different age groups. PSI performed significantly better than CURB-65 for mortality prediction, but its discriminative power decreased with advancing age.

Systemic lupus erythematosus (SLE) has been associated with increased risk of tuberculosis (TB). However, little is known about the extent and risk factors for TB among Asian patient with SLE. We aimed to assess the rate of TB in patients with SLE, and investigate the risk of SLE on TB development using hospital administrative database. This is an historical cohort study of hospital discharge database from 2004 to 2011 to identify cases with SLE and TB using International Statistical Classification of Diseases and Related Health Problems, 9th Revision, Australian Modification (ICD-9-AM) codes. Of 301568 hospitalized patients, 841 (0.3%) patients had SLE, 1843 (0.6%) patients had TB, including 17 SLE patients (2.0%). SLE patients had a significantly higher rate of TB (2.0 vs. 0.6%, p < 0.001) compared to that of patients without SLE. The differences in the higher rate after breaking down was in the pulmonary TB group (1.7 vs. 0.5%, p < 0.00) but not in extrapulmonary TB group (0.4 vs. 0.1%, p = 0.060). Logistic regression analyses showed that SLE was a significant and independent predictor of TB (odds ratio 4.6, 95% CI 2.8-7.5, p < 0.001) after adjustment for factors such as age group, gender, ethnicity, admission class, nutritional deficiency, organ transplantation, and Charlson comorbidity index. SLE patients were found to experience higher rates of tuberculosis in this group of Asian patient population. Patients with SLE should be considered as a high-risk group for TB, active screening for latent patients and treatment for positive TB patients is needed.

OBJECTIVES: Type 1 interferons (IFN-1) are implicated in the pathogenesis of systemic lupus erythematosus (SLE), but most studies have only reported the effect of IFN-1 on mixed cell populations. We aimed to define modules of IFN-1-associated genes in purified leucocyte populations and use these as a basis for a detailed comparative analysis. METHODS: CD4+ and CD8+ T cells, monocytes and neutrophils were purified from patients with SLE, other immune-mediated diseases and healthy volunteers and gene expression then determined by microarray. Modules of IFN-1-associated genes were defined using weighted gene coexpression network analysis. The composition and expression of these modules was analysed. RESULTS: 1150 of 1288 IFN-1-associated genes were specific to myeloid subsets, compared with 11 genes unique to T cells. IFN-1 genes were more highly expressed in myeloid subsets compared with T cells. A subset of neutrophil samples from healthy volunteers (HV) and conditions not classically associated with IFN-1 signatures displayed increased IFN-1 gene expression, whereas upregulation of IFN-1-associated genes in T cells was restricted to SLE. CONCLUSIONS: Given the broad upregulation of IFN-1 genes in neutrophils including in some HV, investigators reporting IFN-1 signatures on the basis of whole blood samples should be cautious about interpreting this as evidence of bona fide IFN-1-mediated pathology. Instead, specific upregulation of IFN-1-associated genes in T cells may be a useful biomarker and a further mechanism by which elevated IFN-1 contributes to autoimmunity in SLE.
RESUMO
AIM: We studied the usefulness of magnetic resonance imaging (MRI) in detecting subclinical inflammation in patients with asymptomatic RA and tested the hypothesis of interleukin (IL)-18 as a marker of disease activity. METHODS: Thirteen RA patients with Disease Activity Score of 28 joints (DAS28) < 2.6 were evaluated. The patients underwent clinical evaluation, laboratory tests and MRI assessment. Imaging of bilateral hands and wrists was performed using validated acquisition and scoring techniques. Serum IL-18 levels were concurrently measured. RESULTS: MRI assessments showed that 92.3% and 76.9% of patients had synovitis and bone marrow edema, respectively, despite being in clinical remission. Eight out of 12 patients (66.7%) had erosions on MRI which were not visualised on plain radiographs. Of all the 182 joints studied for synovitis on MRI, only one had clinical evidence of joint swelling. Comparison of the total sum scores of synovitis between the right and left hand and wrist joints of individual patients showed a significant difference between the two sides. Measurements of IL-18 indicated that a large proportion (54%) of the patients had undetectable or very low levels of the cytokine. CONCLUSION: MRI is more sensitive in detecting erosions compared with X-rays, and is superior in its ability to detect subclinical inflammation in RA patients. Despite being in clinical remission, a large majority of patients had imaging-detected synovitis and bone marrow edema. Our study highlights the usefulness of MRI for the accurate evaluation of disease activity. In the utility of MRI, it may be important to assess bilateral hands and wrists, instead of limiting to the dominant side.

Endothelial dysfunction is associated with traditional and systemic lupus erythematosus (SLE)-specific risk factors, and early data suggest reversibility of endothelial dysfunction with therapy. The clinical relevance of endothelial function assessment has been limited by the lack of studies, demonstrating its prognostic significance and impact on early myocardial function. Therefore, we aimed to determine the association between endothelial and myocardial diastolic function in SLE women. Women with SLE and no coronary artery disease were prospectively recruited and underwent radionuclide myocardial perfusion imaging (MPI) (Jetstream, Philips, the Netherlands) to exclude subclinical myocardial ischemia. Cardiac and vascular functions were assessed in all patients (Alpha 10, Aloka, Tokyo). Diastolic function was assessed using pulse wave early (E) and late mitral blood inflow and myocardial tissue Doppler (mean of medial and lateral annulus e') velocities. Endothelial function was measured using brachial artery flow-mediated vasodilatation (FMD%). Univariate and multivariate linear regressions were used to assess the association between FMD% and myocardial diastolic function, adjusting for potential confounders. Thirty-eight patients without detectable myocardial ischemia on MPI were studied (mean age 44 ± 10 years; mean disease duration 14 ± 6 years). About 61 % of patients had normal diastolic function (E/e' ≤ 8), and 5 % of patients had definite diastolic dysfunction with E/e' > 13 (mean 7.1 ± 2.9). FMD% was associated with E/e' (regression coefficient ß = -0.35; 95 % CI -0.62 to -0.08; p = 0.01) independent of systolic blood pressure, age, and SLICC/ACR Damage Index.

AIMS: To describe the spectrum of diseases seen in an outpatient setting in the Singapore General Hospital, the largest tertiary referral centre in Singapore. METHODS: In this cross-sectional study, medical records of patients scheduled for an appointment at the rheumatology specialist outpatient clinics over a 4-month period (10 August 2010-31 December 2010) were reviewed. Primary diagnoses documented by the attending physician at the latest visit were recorded. RESULTS: Among 4180 patients (29.5% male; mean [SD] age: 53.5 [15.1] years; 77.0% Chinese, 8.0% Malay, 8.8% Indian and 6.2% others), the spectrum of diseases seen was as follows [disease - definite n (%), probable n (%)]: Arthritis: rheumatoid arthritis - 958 (22.9%), 68 (1.6%); osteoarthritis - 452 (10.8%), 39 (0.9%); crystal arthritis - 417 (10.0%), 18 (0.4%); spondyloarthritis - 227 (5.4%), 61 (1.5%); psoriatic arthritis - 158 (3.8%), 9 (0.2%); other inflammatory arthritis - 153 (3.7%), 94 (2.2%); Connective tissues diseases: systemic lupus erythematosus - 412 (9.9%), 26 (0.6%); vasculitis - 105 (2.5%), 22 (0.5%); Sjögren's syndrome - 81 (1.9%), 32 (0.8%); overlap syndromes - 73 (1.8%); scleroderma - 50 (1.2%), 4 (0.1%); undifferentiated connective tissue diseases - 45 (1.1%), 106 (2.5%); myositis - 41 (1.0%), 12 (0.3%); antiphospholipid syndrome - 22 (0.5%), 7 (0.2%); polymyalgia rheumatica - 16 (0.4%); Others: soft tissue rheumatism - 155 (3.7%); osteoporosis - 61 (1.5%); other non-rheumatologic conditions - 189 (4.5%); other rheumatologic conditions - 67 (1.6%). CONCLUSION: Rheumatoid arthritis, osteoarthritis and crystal arthritis were the three most common rheumatological diseases seen in a tertiary referral centre serving a multi-ethnic urban Asian population in Singapore.

INTRODUCTION: Whether fi nal height is associated with quality of life and mental health is a matter of epidemiological and medical concern. Both social and biological explanations have been previously proposed. This study aims to assess the associations in ethnic Chinese in Singapore. MATERIALS AND METHODS: A cross-sectional study of 4414 respondents aged at least 21 years seen at a major polyclinic was performed. Socioeconomic and behavioural features of the sample and the Singapore population of similar ages were comparable. Height was measured by clinic nurses using an ultrasonic height senor. Participants were interviewed for socioeconomic, behavioural, health and quality of life information. Clinical morbidity data was collected from the participants' treating physicians. The SF-6D utility index and its Mental Health domain were the main endpoints. Linear and ordinal logistic regression models were used to analyse the utility index and the Mental Health scores, respectively. RESULTS: Having adjusted for age and gender, the Mental Health domain (P <0.01) was associated with height but the utility index was not. Further adjustment for health, socioeconomic and behavioural covariates made little difference. Analyses based on height categories showed similar trends. CONCLUSION: Adult height has a positive association with mental health as measured by the SF-6D among ethnic Chinese in Singapore. Socioeconomic status and known physical health problems do not explain this association. Adult height had no association with SF-6D utility index scores.

OBJECTIVES: To compare the SSc-line immunoassay (LIA) with conventional techniques of antibody detection, to evaluate its diagnostic utility and to describe clinical associations of antibodies in Asian SSc patients. METHODS: Stored sera from patients with SSc (n = 68), SLE (n = 49), OA (n = 41) and normal controls (NCs, n = 32) were evaluated. Cohen's κ and Bland-Altman plots were used to evaluate agreement. RESULTS: There was good agreement between LIA and ELISA for anti-Scl-70 (κ = 0.97), anti-CENPA (κ = 0.83), anti-CENPB (κ = 0.96) and anti-PmScl100 (κ = 1.00) (5.48-8.22% of values outside the 95% limits of agreement using Bland-Altman plots), and between LIA and IIF for anti-CENPA (κ = 0.81) and anti-CENPB (κ = 0.77) (P < 0.001). Using LIA, of 32 (32/68, 47%) SSc patients negative for anti-Scl-70 and anti-CENPA/B, 5 (5/32, 15%) were positive for anti-Ku, -Nor90, -fibrillarin and -RP155. Specificity of each antibody for SSc was at least 97% (vs OA/NC) and 94% (vs SLE), except for anti-Ro52 (63%). Anti-CENPB was associated with joint pain [odds ratio (OR) 0.17], interstitial lung disease (OR 0.24) and telangiectasia (OR 4.00) (P < 0.05). Anti-Ro60 was associated with pulmonary arterial hypertension (OR 3.89, P = 0.041). CONCLUSION: The SSc-LIA has good agreement with conventional techniques for selected antibodies and has good diagnostic utility.

OBJECTIVE: To investigate the influence of response shift (RS) on health-related quality of life (HRQOL) and utility assessment among patients undergoing total knee replacement. METHODS: Consenting patients undergoing total knee replacement were interviewed to determine their HRQOL by using the six-dimensional health state short form, derived from SF-36, and the EuroQol five-dimensional questionnaire at baseline (pretest 1) and the six-dimensional health state short form, derived from SF-36, at 6 (pretest 2) and 18 months after surgery (post-test). RS was studied by using a "then-test" approach by contacting participants 18 months after surgery and asking them to evaluate their HRQOL at baseline (then-test 1) and at 6 (then-test 2) and 18 months after surgery. RS was calculated as the score difference between pretest and then-test scores for a given time point. Relationships between RS and external variables were explored by using univariate and multiple liner regression analyses. RESULTS: In 74 subjects (63% response rate, median age 68 years), median (interquantile range) six-dimensional health state short form, derived from SF-36, scores for then-tests at baseline (0.48 [0.42-0.49]) and at 6 months (0.72 [0.66-0.79]) after surgery were significantly different from respective pretest scores (0.61 [0.58-0.68] at baseline, P = 0.000; 0.69 [0.63-0.72] at 6 months, P = 0.000), showing RS at both time points. RS at baseline (0.14 [0.08-0.20]) was significantly larger than that at 6 months (-0.05 [0.14 to 0.00], P = 0.000). EuroQol five-dimensional questionnaire pretest and then-test scores at baseline also differed significantly (0.69 [0.17-0.73] vs. -0.18 [-0.23 to 0.00], P = 0.000). RS at baseline was not affected by assessed demographic or medical variables. RS at 6 months was greater in subjects with more years of education (16% of variance in multiple liner regression, P < 0.01). CONCLUSION: RS was present and impacted HRQOL and utility assessment among patients undergoing total knee replacement before and 6 months after surgery.

OBJECTIVES: The objective of this study was to investigate the impact of health literacy (HL) on health-related quality of life (HRQoL) and utility assessment among patients with rheumatic diseases. METHODS: HL was measured by the rapid estimate of adult literacy in medicine (REALM) and was characterized as low or adequate. HRQoL and utility scores were assessed using the SF-36, SF-6D, and EQ-5D. Comparisons of sociodemographics and HRQoL in patients with low or adequate HL were made using t test, chi-square, or Mann-Whitney U tests. Spearman's correlation and partial correlations were used to study the relationship between HL, HRQoL, and utility scores, with significant correlations further explored using multiple linear regression models. RESULTS: Data were analyzed from 199 subjects. Patients with adequate HL had significantly higher education levels, better dwelling status, lower disease activity, and better physical functioning (PF). There was a significant although weak correlation between HL level and PF. After adjustment, HL level was shown to independently explain 3.7% of the variance in the PF score. Nevertheless, there was no impact of HL on utility assessment or other HRQoL domains. CONCLUSION: HL did not impact HRQoL in general, but was found to have a weak impact on the PF of patients with rheumatic diseases.
