Key barriers to gout care: a systematic review and thematic synthesis of qualitative studies

Perspective of Dutch Patients with Gout on Continuation or Discontinuation of Urate-Lowering Therapy During Remission: A Mixed-Methods Study

OBJECTIVE

Long-term gout management is based on reducing serum urate by using urate-lowering therapy (ULT). A lifelong treat-to-target approach is advocated, although a ULT (taper to) stop attempt can be considered (treat-to-avoid symptoms approach) during remission. Exploring the beliefs of patients with gout on long-term ULT strategies during remission is important for optimizing gout management. We aimed to identify factors that influence the decision for continuation or discontinuation of ULT and to determine their relative importance according to patients with gout in remission.

METHODS

A mixed-methods design was used. First, semistructured interviews (substudy 1) were conducted to identify barriers and facilitators for the (dis)continuation of ULT using inductive thematic analysis. Afterwards, these barriers/facilitators were summarized into neutrally phrased items and used in a maximum difference scaling study (substudy 2) to determine their relative importance using the rescaled probability score.

RESULTS

Substudies 1 and 2 included 18 and 156 patients, respectively. Substudy 1 yielded 22 items within 10 overarching themes. Substudy 2 revealed that the perceived risk of joint damage and gout flares and that ULT use gives some assurance were the most important items. The costs, ease of receiving ULT, and its practical use were the least important items.

CONCLUSION

These results can aid shared decision-making and provide input for what is important to discuss with patients with gout in remission when they consider ULT discontinuation. The emphasis should be on the risk of having gout flares and joint damage, not so much on facilitating how easily medication is received.

Support needs of gout patients and suitability of eHealth to address these needs

Objectives

To investigate the support needs of patients with gout regarding information, communication, treatment and disease monitoring, and patients' views on and preferences for eHealth applications to address these needs.

Methods

A focus group study using purposive sampling was conducted. Three focus group sessions with a duration of 2 h per group were held with in total of 23 patients using urate-lowering therapy, recruited from primary and secondary care. Audio recordings were transcribed, and data were analysed using thematic analysis.

Results

Eight themes were identified. Five themes addressed support needs of gout patients and suitability of eHealth in addressing those needs: (1) Timely access to healthcare, especially during flares; (2) (personalized) information regarding diagnosis, medication, and diet; (3) insight into uric acid levels and medication side effects through blood monitoring; (4) better coordination across primary and secondary care; and (5) self-management and shared responsibility over care for maintaining health. Three themes addressed eHealth in general: (1) receptive towards eHealth in gout care; (2) the preference for eHealth to have a complementary role (i.e. not replacing face-to-face) contact with healthcare providers; and (3) preferences on eHealth use and functionalities.

Conclusion

Patients expressed various needs regarding their disease management and projected a supporting role for eHealth in (self)management of gout. Addressing the needs and preferences of patients could enhance their understanding of the disease and treatment, self-management, and possibly health outcomes.

Leveraging Habits to Improve Adherence to Gout Medications: A Qualitative Study

OBJECTIVE

This study investigates patients' medication-taking routines and the feasibility of harnessing habit formation through context cues and rewards to improve medication adherence.

METHODS

Semistructured qualitative interviews with patients with gout from an urban health care system were conducted to explore typical medication-taking behavior, experiences using electronic pill bottles, barriers to adherence, existing context cues, and potential cues and rewards for habit-forming behavior. Medication-taking patterns were recorded for six weeks using electronic pill bottles before interviews to inform discussion. Transcribed interviews were analyzed to generate themes using codes developed by the study team, with representative quotations selected as illustrations.

RESULTS

We conducted interviews with 15 individuals (mean age 60.6 [SD 20.3] years, three women [20%], and nine White patients [60%]). Pill bottle-recorded adherence to urate-lowering therapy (ULT) was high (mean 0.91 [SD 0.10]), and one patient was experiencing an active gout flare. Five key themes emerged: (1) reasons for nonadherence, (2) internal and external motivations for adherence, (3) structured routines around taking medications, (4) rewards for good medication adherence, and (5) the role of pill cap technology in medication-taking.

CONCLUSION

The importance of a predictable, structured routine in which participants could incorporate their medication-taking behavior emerged as a key factor that promoted consistent adherence. Further, identifying context cues and reminders seemed to promote incorporation of medication-taking into routines. Therefore, habit-based interventions that use context cues to establish routines around medication-taking may be a feasible strategy to improve adherence in patients with chronic conditions such as gout.

Adherence and Treat-to-Target Benchmarks in Older Adults With Gout Initiating Urate-Lowering Therapy in Ontario, Canada: A Population-Based Study

OBJECTIVE

We sought to evaluate urate-lowering therapy (ULT) adherence and treatment-to-target (T2T) serum uric acid (SUA) levels among older adults with gout starting ULT.

METHODS

We performed a population-based retrospective cohort study in Ontario, Canada in patients with gout aged ≥66 years newly dispensed ULT between 2010 and 2019. We defined successful T2T as patients having SUA levels <360 μmol/L (6 mg/dL) within 12 months after ULT dispensation. We also assessed adherence to ULT. Multilevel logistic regression clustered by ULT prescriber evaluated patient, physician, and prescription factors associated with reaching target SUA levels.

RESULTS

Among 44,438 patients (mean ± SD age 76.0 ± 7.3 years; 64.4% male), 30,057 (67.6%) patients had ≥1 SUA test completed. Overall, 52.3% patients reached SUA target within 12 months, improving from 45.2% in 2010 to 61.2% in 2019 (P < 0.0001). ULT adherence was 55.3% overall and improved annually. Key factors associated with achieving T2T included febuxostat treatment (odds ratio [OR] 11.40, 95% confidence interval [95% CI] 5.10-25.43) (was only dispensed in 88 patients), ULT adherence (OR 5.17, 95% CI 4.89-5.47), allopurinol starting doses >50 mg (OR 2.53, 95% CI 2.14-2.99), colchicine/oral glucocorticoids co-prescription (OR 1.24, 95% CI 1.14-1.34), and ULT prescription from a rheumatologist.

CONCLUSION

Only 52.3% of patients achieved an optimal SUA level within 1 year of ULT initiation. ULT adherence was suboptimal, although improving over time. ULT adherence and higher allopurinol starting doses had the strongest associations of achieving a target SUA level. This study highlights room for improvement in gout management and potential strategies to address care gaps.

Global, regional, and national burden of gout, 1990-2020, and projections to 2050: a systematic analysis of the Global Burden of Disease Study 2021

BACKGROUND

Gout is an inflammatory arthritis manifesting as acute episodes of severe joint pain and swelling, which can progress to chronic tophaceous or chronic erosive gout, or both. Here, we present the most up-to-date global, regional, and national estimates for prevalence and years lived with disability (YLDs) due to gout by sex, age, and location from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021, as well as forecasted prevalence to 2050.

METHODS

Gout prevalence and YLDs from 1990 to 2020 were estimated by drawing on population-based data from 35 countries and claims data from the USA and Taiwan (province of China). Nested Bayesian meta-regression models were used to estimate prevalence and YLDs due to gout by age, sex, and location. Prevalence was forecast to 2050 with a mixed-effects model.

FINDINGS

In 2020, 55·8 million (95% uncertainty interval 44·4-69·8) people globally had gout, with an age-standardised prevalence of 659·3 (525·4-822·3) per 100 000, an increase of 22·5% (20·9-24·2) since 1990. Globally, the prevalence of gout in 2020 was 3·26 (3·11-3·39) times higher in males than in females and increased with age. The total number of prevalent cases of gout is estimated to reach 95·8 million (81·1-116) in 2050, with population growth being the largest contributor to this increase and only a very small contribution from the forecasted change in gout prevalence. Age-standardised gout prevalence in 2050 is forecast to be 667 (531-830) per 100 000 population. The global age-standardised YLD rate of gout was 20·5 (14·4-28·2) per 100 000 population in 2020. High BMI accounted for 34·3% (27·7-40·6) of YLDs due to gout and kidney dysfunction accounted for 11·8% (9·3-14·2).

INTERPRETATION

Our forecasting model estimates that the number of individuals with gout will increase by more than 70% from 2020 to 2050, primarily due to population growth and ageing. With the association between gout disability and high BMI, dietary and lifestyle modifications focusing on bodyweight reduction are needed at the population level to reduce the burden of gout along with access to interventions to prevent and control flares. Despite the rigour of the standardised GBD methodology and modelling, in many countries, particularly low-income and middle-income countries, estimates are based on modelled rather than primary data and are also lacking severity and disability estimates. We strongly encourage the collection of these data to be included in future GBD iterations.

[Gout, beyond the joint: How should we treat it?]

Gout is a disease caused by the chronic deposition of monosodium urate crystals. Its clinical presentation as an acute, self-limiting arthritis and the belief that it is a banal, self-inflicted disease have led to its poor management. Despite advances in the knowledge of the disease and the simplicity of its management, no more than 30% of patients are well treated. In Spain, the prevalence of gout is 2.5% and its incidence is increasing. In the following article we will review the pathogenesis of gout and hyperuricaemia, highlighting the greater weight of genetics and renal function over diet. We will look at the consequences of crystal deposition. Gout, in addition to its joint presentation and renal involvement, has been shown to be an independent cardiovascular risk factor. Hypouricemic therapy is the most important treatment, as it is the one that dissolves the crystals and cures the disease. This requires the sustained achievement of uricemia levels below 6mg/dl. We will also review preventive and flares treatment, as well as the role of patient education in terms of both lifestyle and dietary habits and adherence to pharmacological treatment.

Health-related quality of life in gout patients in Madinah Region, Saudi Arabia

Background

Gout can significantly impact health-related quality of life (HRQoL) due to excruciating pain, chronic arthropathy, and associated comorbidities. The objective of our study was to evaluate HRQoL among patients diagnosed with gout in the Madinah region of Saudi Arabia.

Materials and Methods

The research took place in the Madinah Region, where eligible adult participants aged 18 years or older, having a confirmed history, or present diagnosis of gout were enrolled using medical records from 2016 to 2022. To gather data, patients were invited to participate in telephone-based interviews and complete the Short Form-36 (SF-36) questionnaire.

Results

The majority of participants were male (81.5%), and 31-39 years form the largest group (37.0%). Most participants were married (86.4%), and the majority possess university and postgraduate education (70.4%). The respondents' self-reported assessments were as follows: physical function (69.9), limitation due to physical health (74.1), emotional problem (75.8), energy or fatigue (61.6), emotional well-being (68.9), social functioning (76.6), pain (78.9), and general health (63.8).

Conclusions

HRQoL among patients with gout was not significantly affected.

Estimation of adherence to urate-lowering therapy in people living with gout using Australia's Pharmaceutical Benefits Scheme and patient-reported dosing

AIMS

The aim of this study was to estimate adherence to urate-lowering therapy (ULT), predominately allopurinol, from Australia's Pharmaceutical Benefits Scheme (PBS) claims database in association with (1) patient-reported doses and (2) World Health Organization's (WHO) defined daily doses (DDD), namely, allopurinol (400 mg/day) or febuxostat (80 mg/day).

METHODS

Proportion of days covered (PDC) was calculated in 108 Gout App (Gout APP) trial participants with at least two recorded ULT dispensings in an approximately 12-month period before provision of intervention or control apps. Adherence was defined as PDC ≥80%. We measured the correlation between the two methods of calculating PDC using a Wilcoxon signed rank test. Agreement between ULT-taking status (self-reports) and ULT-dispensed status (PBS records) was tested with Cohen's kappa (κ), and positive and negative percent agreement.

RESULTS

Allopurinol was prescribed in 93.5% of participants taking ULT. Their self-reported mean daily dose (SD) was 291 (167) mg/day. Mean PDC (SD) for allopurinol was 83% (21%) calculated using self-reported dose, and 63% (24%) using WHO's DDD. Sixty-three percent of allopurinol users were identified as adherent (PDC ≥80%) using self-reported dose. There was good agreement between self-reported ULT use and PBS dispensing claims (κ = 0.708, P < .001; positive percent agreement = 90%, negative percent agreement = 82%).

CONCLUSIONS

Participant-reported allopurinol daily doses, in addition to PBS dispensing claims, may enhance confidence in estimating PDC and adherence compared to using DDD. This approach improves adherence estimations from pharmaceutical claims datasets for medications where daily doses vary between individuals or where there is a wide therapeutic dose range.

Adherence to Healthy and Unhealthy Plant-Based Diets and the Risk of Gout

Importance

Plant-based diets are increasing in popularity due, in part, to their health benefits for selected cardiometabolic diseases as well as favorable environmental impact. Little is known about how such a diet is related to gout risk.

Objective

To examine associations between adherence to a plant-based diet (including healthy and unhealthy versions of this diet), as well as its 18 individual food groups, and incident gout.

Design, Setting, and Participants

This prospective cohort study used data from population-based cohorts of US men and women enrolled in the Health Professionals Follow-Up Study (1986-2012) and Nurses' Health Study (1984-2010). Participants were men and women free of gout at baseline. Statistical analyses were performed over March 2020 to August 2023.

Exposures

An overall plant-based diet index (PDI), as well as healthy (hPDI) and unhealthy (uPDI) versions of this index that emphasize healthy and less healthy plant-based foods, respectively. These diet indices were comprised of 18 food groups, assessed using a validated semiquantitative food frequency questionnaire.

Main Outcomes and Measures

Incident cases of gout that were confirmed with a supplementary questionnaire to meet the preliminary American College of Rheumatology survey criteria for gout. Cox proportional hazards regression models were used to evaluate multivariable-adjusted associations of all 3 PDIs with incident gout using quintiles (Q) of adherence.

Results

Among a total of 122 679 participants (mean [SD] age, 53.8 [9.8] years among 43 703 men; mean [SD] age, 50.9 [7.2] years among 78 976 women) over 2 704 899 person-years of follow-up, 2709 participants experienced incident gout. The overall PDI was not significantly associated with gout in either cohort (Q5 vs Q1 pooled hazard ratio [HR], 1.02 [95% CI, 0.89-1.17]; P for trend = .63). In the pooled analysis, hPDI was significantly inversely associated with risk of gout (Q5 vs Q1 HR, 0.79 [95% CI, 0.69-0.91]; P for trend = .002), while the uPDI was positively associated with risk of gout (Q5 vs Q1 HR, 1.17 [95% CI, 1.03-1.33]; P for trend = .02), particularly in women (Q5 vs Q1 HR, 1.31 [95% CI, 1.05-1.62]; P for trend = .01). In analysis of individual food groups, higher intakes of certain healthy plant foods, such as whole grains (pooled HR per 1 serving/d, 0.93 [95% CI, 0.89-0.97]) and tea and coffee (pooled HR per 1 serving/d, 0.95 [95% CI, 0.92-0.97]), as well as dairy (pooled HR per 1 serving/d, 0.86 [95% CI, 0.82-0.90]), were independently associated with a lower risk of gout, while selected unhealthy plant foods, such as fruit juice (pooled HR per 1 serving/d, 1.06 [95% CI, 1.00-1.13]) and sugar-sweetened beverages (pooled HR per 1 serving/d, 1.16 [95% CI, 1.07-1.26]) were associated with increased risk of gout.

Conclusions and Relevance

The findings of this prospective cohort study of PDIs and gout support current dietary recommendations to increase consumption of healthy plant foods while lowering intake of unhealthy plant foods to mitigate gout risk.

A content analysis of medication adherence material in patient educational resources about gout

Objective

This study aimed to investigate how medication adherence is addressed in online gout resources in six countries. We investigated how often adherence was referred to, the strategies suggested to improve patient adherence, and the types of nonadherence that were targeted. We also examined the readability of the adherence material.

Methods

A content analysis was conducted on 151 online gout resources from medical and health organisations in six predominantly English-speaking countries. Two reviewers coded the content of the websites into categories (kappa 0.80). The analysis involved coding the resources for reasons for nonadherence, and adherence-promoting strategies. Flesch-Kincaid Reading Ease scores and word count were also computed.

Results

Out of 151 websites examined, 77 websites discussed medication adherence (51%), with intentional nonadherence being more prevalent than unintentional nonadherence. 67 websites targeted different types of nonadherence, including drug-specific concerns (50%), misconceptions of gout curability and the necessity of medication (16%), forgetfulness (16%), and other practical challenges (5%). Strategies to promote adherence were found in one-third of the websites, with medication education being the most prevalent strategy (17%), followed by healthcare provider engagement (13%) and memory aid strategies (6%). On average, about 11% of the words (89.27, SD = 76.35) in the entire document were focused on adherence. Difficult reading comprehension was found in one-fifth of adherence-related websites.

Conclusion

Findings reveal limited medication adherence coverage and narrow strategies in online gout resources. Improved adherence portrayal is needed for effective gout management through comprehensive strategies and clear, understandable information.

Association between patient adherence and treat-to-target in gout: A cross-sectional study

The implementation of a treat-to-target (T2T) approach has been widely recommended for achieving optimal outcomes in gout treatment, as substantiated by a wealth of compelling evidence. However, a paucity of knowledge exists regarding the barriers hindering effective T2T management in China. This study seeks to investigate the factors contributing to treatment failure within the context of the T2T strategy. A cross-sectional, multi-center investigation was conducted, involving the completion of electronic questionnaires by outpatients undergoing urate-lowering treatment for a duration exceeding 6 months. These questionnaires encompassed demographic information, disease-related conditions, comorbid conditions, and management. The study analyzed factors associated with serum uric acid levels exceeding 360 µmol/L, poor disease control, and poor medication adherence. A total of 425 valid questionnaires were collected, representing 90.8% of the patients. The T2T implementation rate was 26.82% (n = 114). Factors linked to serum uric acid levels surpassing 360 µmol/L included moderate medication adherence (odds ratio (OR) = 2.35; 95% confidence interval (CI) 1.17-4.77; P = .016), poor medication adherence (OR = 4.63; 95% CI 2.28-9.51; P < .001), and management by general practitioners (OR = 0.60; 95% CI 0.37-0.97; P = .036). The rate of well-controlled patients was 14.35% (n = 61). Predictors of not well controlled encompassed the presence of tophi (OR = 2.48; 95% CI 1.17-5.61; P = .023), general medication adherence (OR = 2.78; 95% CI 1.28-6.05; P = .009), poor medication adherence (OR = 6.23; 95% CI 2.68-14.77; P < .001), and poor patient's perception of gout (OR = 4.07; 95% CI 1.41-13.91; P = .015). A poor medication adherence rate of 55.29% (n = 235) was observed, with lower rates of poor medication adherence associated with the use of febuxostat (OR = 0.35; 95% CI 0.14-0.83; P = .02), uric acid levels exceeding 360 µmol/L (OR = 3.05; 95% CI 1.84-5.12; P = .00), moderate patient education (OR = 2.28; 95% CI 1.29-4.15; P = .01), moderate diet control (OR = 1.98; 95% CI 1.17-3.41; P = .01), and poor diet control (OR = 3.73; 95% CI 1.26-12.83; P = .02). The rate of T2T implementation in China is notably low among patients undergoing urate-lowering treatment of gout beyond 6 months. Importantly, medication adherence demonstrates a significant association with T2T outcomes.

The relationship between education attainment and gout, and the mediating role of modifiable risk factors: a Mendelian randomization study

Objective

To investigate the causal relationship between educational attainment (EA) and gout, as well as the potential mediating effects of individual physical status (IPS) such as body mass index (BMI) and systolic blood pressure (SBP) and lifestyle habits (LH) including alcohol intake frequency (drinking), current tobacco smoking (smoking), and time spent watching television (TV).

Methods

Utilizing two-sample Mendelian randomization (MR), we analyzed the causal effects of EA on gout risk, and of IPS (BMI and SBP) and LH (smoking, drinking, and TV time) on gout risk. Multivariable MR (MVMR) was employed to explore and quantify the mediating effects of IPS and LH on the causal relationship between EA and gout risk.

Results

An elevation of educational attainment by one standard deviation (4.2 years) exhibited a protective effect against gout (odds ratio 0.724, 95% confidence interval 0.552-0.950; p = 0.020). We did not observe a causal relationship between smoking and gout, but BMI, SBP, drinking, and TV time were found to be causal risk factors for gout. Moreover, BMI, SBP, drinking, and TV time acted as mediating factors in the causal relationship between EA and gout risk, explaining 27.17, 14.83, 51.33, and 1.10% of the causal effects, respectively.

Conclusion

Our study indicates that having a genetically predicted higher level of EA may provide protection against gout. We found that this relationship is influenced by IPS factors such as BMI and SBP, as well as LH including drinking and TV time.

Healthcare professionals' perspectives and experiences of osteoporosis medication treatment: a qualitative systematic review

This systematic review aimed to explore healthcare professionals' (HCPs) experiences and perspectives of osteoporosis medication treatment through thematic synthesis of qualitative studies. We found themes about how osteoporosis is perceived as a disease, treatment decision-making and what empowers HCPs to provide the best possible care.

PURPOSE

The systematic review aimed to describe the perspectives and experiences of HCPs regarding osteoporosis medication treatment.

METHODS

We performed searches in four electronic databases (Medline, Embase, PsycINFO and CINAHL) from database inception until May 2023 in any language. Data was analysed through inductive thematic synthesis.

RESULTS

We included 27 primary studies that incorporated the views of 495 different HCPs. The following themes were identified: low-priority disease, challenges in treatment decision-making, minimising drug burden, conscious of communication barriers, fragmented care and advice, confidence through experience and collaboration.

CONCLUSIONS

HCPs were enthusiastic about optimising osteoporosis care through interprofessional collaboration and expertise, as well as educating and monitoring patients on treatment. They advocated for safety, comfort and reducing overall drug burden, especially in older patients with comorbidities. However, they had differences in opinions regarding who has responsibility for diagnosing and treating osteoporosis and struggled to provide the best possible care due to competing priorities, limited time and lack of adequate knowledge or evidence. The findings highlight the important and complementary role of different HCPs in osteoporosis treatment through a multidisciplinary model of care.

Validation of gout diagnosis in electronic primary care medical records: A population-based study

OBJECTIVE

The main objective of the study was to see the concordance between the diagnosis of gout recorded in primary care electronic medical records and the ACR/EULAR 2015 classification criteria.

METHODS

A cross-sectional study was conducted using electronic medicals records in 7 primary care centres of Barcelona. Patients' data to study clinical diagnose and management was gathered from the primary care electronic medical records of the Catalonian health institute (Institut Català de la Salut, ICS) and phone interview. Patients were considered to have gout if they scored 8 or more points on the EULAR/ACR 2015 classification criteria for gout.

RESULTS

In total, 70.9% of the patients with a gout diagnosis met ACR/EULAR 2015 criteria. Adding a hyperuricemia in a blood test in the EMR increased the percentage to 78.9%. 29.8% of the gout patients were not receiving urate-lowering therapy. 62.3% of the treated patients did not achieve the target uricemia (< 6mg/dL).

CONCLUSIONS

The majority of gout patients from primary care electronic medical records fulfil ACR/EULAR gout criteria. This database can be used for observational studies. In most of the gout patients the urate target was not achieved.

Cohort study investigating gout flares and management in UK general practice

BACKGROUND

Gout is the most common inflammatory arthritis and is almost exclusively managed in primary care, however the course and severity of the condition is variable and poorly characterised. This research aims improve understanding about the frequency of, and factors associated with, gout flares in the UK and characterise the factors associated with the initiation of ULT.

METHODS

Using the Clinical Practice Research Database, patients with a coded incident gout diagnosis without a prior prescription for urate-lowering therapy (ULT) were identified. Gout flares post diagnosis and ULT initiation were identified through prescribing and coded data. Patient characteristics, co-morbidities and co-prescribing were co-variants. Factors associated with gout flares and ULT initiation were analysed using cox-proportional hazard model and logistic regression.

RESULTS

Fifty-one thousand seven hundred eighty-four patients were identified: 18,605 (35.9%, 95%CI 35.5-36.3%) had experienced ≥ 1 recurrent flare, 17.4% (95%CI 17.1-17.8%) within 12 months of diagnosis. Male sex, black ethnicity, higher BMI, heart failure, CKD, CVD and diuretic use were associated with flares, with the highest HR seen with high serum urate levels (≥ 540 µmol/L HR 4.63, 95%CI 4.03-5.31). ULT initiation was associated with similar variables, although higher alcohol intake and older age were associated with lower odds of ULT initiation but were not associated with flares. ULT was initiated in 27.7% (95%CI 27.3-28.0%): 5.7% (95%CI 5.5-5.9%) within 12 months of diagnosis. ULT initiation rates were higher in patients with recurrent flares.

CONCLUSION

Approximately one in six people with incident gout had a second flare within 12 months. Factors associated with flare recurrence and ULT initiation were similar, but ULT initiation occurred later after diagnosis than previously thought.

Knowledge and attitudes of gout patients and their perspectives about diagnosis and management: A cross-sectional study in Saudi Arabia

BACKGROUND

Gout is a chronic noncommunicable disease that might lead to multiple systemic complications if it is left untreated. The knowledge, attitudes, and perceptives among patients toward the diagnosis and management of gout are important indicators in determining the prognosis and predicting sequelae of the disease. This cross-sectional survey aimed to assess the knowledge, attitudes, and perspectives of patients diagnosed with gout toward the disease diagnosis and treatment.

METHODOLOGY

An observational cross-sectional study was conducted at university clinics and local health facilities in central Riyadh, Saudi Arabia, for the duration between April and August 2022. Pearson χ2 test was used to determine the difference in the proportion of patients who adapt different attitudes and perspectives in terms of their demographic variables. Statistical significance was defined as a p value less than .05.

RESULTS

Two-hundred thirteen patients were involved in this study. The majority of the patients (84.0%) were diagnosed for more than 1 year. The majority of the patients (76.5%) were aged 25-60 years when they were diagnosed with gout. The most common complaint at the time of the diagnosis was joint pain (73.7%). The most commonly reported gout medication treatment being used was allopurinol accounting for 23.0%. The majority of the patients (83.6%) were satisfied regarding the effects of gout management on their job performance, work life, and careers. The vast majority (97.5%) reported that they are satisfied with the health service provided.

CONCLUSION

The patients diagnosed with gout in Saudi Arabia exhibited a satisfactory level of information, attitude, and perspectives regarding their condition. The participants expressed a significant degree of satisfaction with the impact of gout management on their occupational performance, work-life balance, and professional plans. Additional research is necessary to ascertain the risk factors associated with gout and provide suitable preventative interventions.

Optimizing adherence to allopurinol for gout: patients' perspectives

AIMS

Poor adherence to allopurinol among people with gout contributes to suboptimal gout management. This study sought to understand the facilitators and barriers to allopurinol adherence across the three stages of medication adherence, and patient perspectives on strategies to improve adherence, including self-monitoring urate concentration.

METHODS

Semi-structured interviews were conducted with 26 people with gout, previously or currently taking allopurinol. De-identified verbatim transcripts were thematically analysed using an inductive and deductive approach.

RESULTS

Facilitators of adherence during allopurinol initiation were motivation to prevent gout flares and trust in the advice of their healthcare professionals (HCPs). Reluctance to commence long-term medication was a barrier to allopurinol initiation. Believing in the effectiveness and necessity of allopurinol and reminder systems were facilitators of implementation. Barriers to implementation included forgetfulness, gout flares and limited feedback on allopurinol's effectiveness. Patients discontinued therapy when allopurinol was perceived as ineffective or unnecessary. Discontinuation coincided with patients experiencing gout flares while adhering to allopurinol and receiving suboptimal advice about gout management. Patients identified receiving accurate advice from HCPs and regular urate monitoring for feedback on allopurinol's effectiveness as potential strategies to improve adherence. Perceived benefits of self-monitoring urate as a strategy to promote adherence included the ability to self-manage gout and make informed decisions about allopurinol therapy with their HCP.

CONCLUSION

Patient perceptions of the effectiveness and necessity of allopurinol influenced intentional adherence during medication initiation, implementation and discontinuation. Strategies that inform patients of their urate control and provide accurate medical advice have the potential to improve adherence to allopurinol.

The nurse's role in managing gout in the modern era: A systematic review of the literature

The current treatment of gout is largely suboptimal, with up to 89% of hospitalizations being preventable due to inadequate care. The present study performed a systematic review in an aim to identify barriers to optimal gout treatment (Q1), understand how frequently nurses are involved in the management of gout (Q2), and examine the role of the nurse in the management of gout (Q3). A systematic review was performed, focusing on studies reporting on the nurse's role in the management of gout and the quality of the gathered items was appraised based on the risk of bias. In total, 15 records fulfilled the eligibility criteria and were used in the present systematic review. The main barriers were attributed to the patient's experiences with gout and lay beliefs, which affected seeking advice and adherence to treatment (Q1). Recently, however, several advances in patient care, including nurse-led clinics, have expanded the nurse's role, accounting for as much as 26% of the annual visits (Q2). Nurse-led interventions, such as education and lifestyle counseling, increased adherence to treatment (Q3). On the whole, nurses are key players in multidisciplinary teams and should be capable of engaging in shared decision-making processes, goal setting, providing patients with education and information, and making appropriate referrals.

What are the core recommendations for gout management in first line and specialist care? Systematic review of clinical practice guidelines

BACKGROUND

Gout is the most common inflammatory arthritis, increasing in prevalence and burden. Of the rheumatic diseases, gout is the best-understood and potentially most manageable condition. However, it frequently remains untreated or poorly managed. The purpose of this systematic review is to identify Clinical Practice Guidelines (CPG) regarding gout management, evaluate their quality, and to provide a synthesis of consistent recommendations in the high-quality CPGs.

METHODS

Gout management CPGs were eligible for inclusion if they were (1) written in English and published between January 2015-February 2022; focused on adults aged ≥ 18 years of age; and met the criteria of a CPG as defined by the Institute of Medicine; and (2) were rated as high quality on the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument. Gout CPGs were excluded if they required additional payment to access; only addressed recommendations for the system/organisation of care and did not include interventional management recommendations; and/or included other arthritic conditions. OvidSP MEDLINE, Cochrane, CINAHL, Embase and Physiotherapy Evidence Database (PEDro) and four online guideline repositories were searched.

RESULTS

Six CPGs were appraised as high quality and included in the synthesis. Clinical practice guidelines consistently recommended education, commencement of non-steroidal anti-inflammatories, colchicine or corticosteroids (unless contraindicated), and assessment of cardiovascular risk factors, renal function, and co-morbid conditions for acute gout management. Consistent recommendations for chronic gout management were urate lowering therapy (ULT) and continued prophylaxis recommended based on individual patient characteristics. Clinical practice guideline recommendations were inconsistent on when to initiate ULT and length of ULT, vitamin C intake, and use of pegloticase, fenofibrate and losartan.

CONCLUSION

Management of acute gout was consistent across CPGs. Management of chronic gout was mostly consistent although there were inconsistent recommendations regarding ULT and other pharmacological therapies. This synthesis provides clear guidance that can assist health professionals to provide standardised, evidence-based gout care.

TRIAL REGISTRATION

The protocol for this review was registered with Open Science Framework (DOI https://doi.org/10.17605/OSF.IO/UB3Y7 ).

Gender differences in illness perceptions and disease management in patients with gout, results from a questionnaire study in Western Sweden

BACKGROUND

Aims were to examine gender differences in patients with gout with regard to a) self-reported gout severity, b) illness perceptions (IP), c) impact on daily activities and Quality of Life (QoL), d) advice from healthcare professionals, e) having changed dietary- or alcohol habits.

METHODS

Adult patients with gout identified in primary and secondary care in Sweden between 2015 and 2017 (n = 1589) were sent a questionnaire about demographics, gout disease severity, IP (using the Brief Illness Perception Questionnaire, (B-IPQ)) and disease management. T-tests, Chi square tests, ANalysis Of VAriance (ANOVA) and linear regression models were used for gender comparisons.

RESULTS

Eight hundred sixty-eight patients responded to the questionnaire. Women, n = 177 (20%), experienced more severe gout symptoms (p = 0.011), albeit similar frequencies of flares compared to men. Women experienced modest but significantly worse IP with regard to consequences, identity, concerns and emotional response (p < 0.05) as well as daily activities such as sleeping (p < 0.001) and walking (p = 0.042) and QoL (p = 0.004). Despite this and a higher frequency of obesity in women (38 vs 21%, P < 0.001) and alcohol consumption in men (p < 0.001), obese women had received significantly less advice regarding weight reduction (47 vs 65%, p = 0.041) compared to obese men. On the other hand, women reported having acted on dietary advice to a larger degree.

CONCLUSIONS

Despite only modestly worse gout severity and perception, women appear to have been given less information regarding self-management than men. These gender differences should be given attention and addressed in clinical care.

The Hong Kong Society of Rheumatology consensus recommendations for the management of gout

Gout is one of the most common noncommunicable diseases in Hong Kong. Although effective treatment options are readily available, the management of gout in Hong Kong remains suboptimal. Like other countries, the treatment goal in Hong Kong usually focuses on relieving symptoms of gout but not treating the serum urate level to target. As a result, patients with gout continue to suffer from the debilitating arthritis, as well as the renal, metabolic, and cardiovascular complications associated with gout. The Hong Kong Society of Rheumatology spearheaded the development of these consensus recommendations through a Delphi exercise that involved rheumatologists, primary care physicians, and other specialists in Hong Kong. Recommendations on acute gout management, gout prophylaxis, treatment of hyperuricemia and its precautions, co-administration of non-gout medications with urate-lowering therapy, and lifestyle advice have been included. This paper serves as a reference guide to all healthcare providers who see patients who are at risk and are known to have this chronic but treatable condition.

Living with gout. Experiences, impact and challenges of the disease. Qualitative study through focus groups

OBJECTIVE

To delve into the experiences of people living with gout regarding its causes and triggers, recommended treatments and therapeutic measures, and the impact of living with this problem.

SUBJECTS AND METHODS

Descriptive qualitative study. Opinion sampling, looking for discursive variability according to sex, age, socioeconomic position and treatments. Three focus groups were made with 11, 6 and 7 people, following a pre-established script of topics. Analysis following thematic content analysis procedures.

RESULTS

Participants were 19 men and 5 women, of different ages, socioeconomic status and treatments. Frequent comorbidities: hypertension and hypercholesterolemia. Genetics and the lack of renal elimination of urate were mentioned as causes of gout. They reported little knowledge of the causes and need more explanations about them. As triggers of the attack they identified: excess food and/or alcohol, trauma, stress or not following the treatment. Various drug treatment and expressed concern about their possible adverse effects were listed. Difficulties in adherence to the recommendations were also described. Non-pharmacological measures: rest, cold, proper footwear, walking, drinking water, and diet were also described. Chronic gout has an important impact on the daily life of patients and their families. Pain invalidates and leads to difficulties in performing daily activities. Irritations and mood swings were reported, which affect their family relationships.

CONCLUSIONS

These findings provide proposals to improve the care of people with gout. Information on its causes, the triggers of the crisis, dietary recommendations and exercise should be improved. The variability of treatments and recommendations on lifestyle should be analysed in depth.

Caring for Australians and New Zealanders With Kidney Impairment Guidelines: Rapid Development of Urate Lowering Therapy Guidelines for People With CKD

Introduction

The slow transformation of new research findings into clinical guidelines is a barrier to providing evidence-based care. The Caring for Australians and New Zealanders with Kidney Impairment (CARI) guidelines are developing models to improve guideline production, one methodology involves more functional concordance between trial groups, such as the Australian Kidney Trials Network (AKTN) and CARI. The objective of this project was to rapidly produce an evidence-based guideline on urate-lowering therapy in patients with chronic kidney disease (CKD), in response to new clinical trial publications on the topic by the AKTN.

Methods

To produce a guideline as rapidly as possible, an existing systematic review was utilized as the evidence base, and then updated with the inclusion of clinical trials that had been published subsequently. A Work Group was convened to review the evidence and compose an appropriate guideline using CARI/GRADE methodology. The group met 3 times over 45 days to formulate the guideline.

Results

The result was a strong recommendation against the use urate-lowering therapies in individuals with CKD (not receiving dialysis) and asymptomatic hyperuricemia. The process of identifying an appropriate existing systematic review, updating the literature search, and synthesizing the evidence, was done by 2 individuals over 15 days. The Work Group was formulated and composed the guideline over 45 days. In all, a new guideline incorporating the most up-to-date evidence was formulated in 60 days.

Conclusion

This method of guideline development represents a potentially new way of releasing guidelines that encapsulates all available evidence in a time-efficient manner.

Achievement of serum uric acid target by rheumatology clinic pharmacists compared with primary care providers in patients with gout

BACKGROUND

The American College of Rheumatology strongly recommends a treat-to-target management strategy to achieve and maintain serum uric acid (sUA) less than 6 mg/dL to decrease risk of gouty flare recurrence and permanent joint damage.

OBJECTIVE

To compare the effectiveness of rheumatology clinic pharmacists and primary care providers (PCPs) in achieving a target sUA goal in patients with gout.

METHODS

This retrospective chart review included patients aged 18 years and older starting urate-lowering therapy (ULT) (allopurinol, febuxostat, or probenecid) for gout between January 1, 2015, and December 31, 2019. Exclusion criteria were ULT use within the previous 6 months, baseline sUA less than 6 mg/dL, and death within 12 months of starting ULT. From ULT initiation, data were collected until sUA less than 6 mg/dL was achieved or a maximum of 12 months. The primary outcome was the percentage of patients who achieved sUA less than 6 mg/dL. Key secondary outcomes were percent reduction in sUA and time to sUA target achievement.

RESULTS

Of 62 patients included in each group, 75.8% of patients in the pharmacist cohort versus 30.6% of patients in the PCP cohort achieved target sUA less than 6 mg/dL (odds ratio 7.09, 95% confidence interval 3.28-16.11, P < 0.001). Patients in the pharmacist-managed group also achieved a greater reduction in mean sUA (-36.7% vs. -26.9% respectively, P = 0.001). Among patients achieving target sUA, median time to target was similar at 92 and 86 days, respectively, despite significantly lower initial mean allopurinol doses in the pharmacist-managed group (102 mg/d vs. 145 mg/d, P < 0.001).

CONCLUSION

The odds of achieving target sUA within 12 months were 7 times higher if gout was managed by a rheumatology clinic pharmacist as compared with a PCP. This study suggests the need for prescriber education and supports expansion of pharmacist-led gout management to primary care settings.

The role of gut microbiota in gout: Is gut microbiota a potential target for gout treatment

Numerous studies have demonstrated that gut microbiota is essential for the host's health because it regulates the host's metabolism, endocrine, and immune systems. In recent years, increasing evidence has shown that gut microbiota plays a role in the onset and progression of gout. Changes in the composition and metabolism of the gut microbiota, result in abnormalities of uric acid degradation, increasing uric acid generation, releasing pro-inflammatory mediators, and intestinal barrier damage in developing gout. As a result, gout therapy that targets gut microbiota has drawn significant interest. This review summarized how the gut microbiota contributes to the pathophysiology of gout and how gout affects the gut microbiota. Additionally, this study explained how gut microbiota might serve as a unique index for the diagnosis of gout and how conventional gout treatment medicines interact with it. Finally, prospective therapeutic approaches focusing on gut microbiota for the prevention and treatment of gout were highlighted, which may represent a future avenue in gout treatment.

Representation Rate and Management of Gout for Patients Discharged From Emergency Departments in Illawarra Shoalhaven Local Health District

Introduction

The estimated prevalence of gout in Western societies is 2.7% to 6.7%. In Australia, there have been increasing rates of hospitalisations for gout flares. Urate-lowering therapy (ULT) is effective in reducing urate burden, which can prevent gout flares and destructive arthropathy. This study assessed the representation rate of patients presenting to the Emergency Department (ED) with crystal arthropathy and the utilisation of ULT in the community for patients with a pre-existing history of gout.

Methods

A retrospective review of electronic records of patients presenting to the ED from the Illawarra Shoalhaven Local Health District was performed. Patients included were coded as per the 10th revision of the International Classification of Diseases coding for crystal arthropathy.

Results

In all, 18.8% of all crystal arthropathy encounters to the ED were repeat presentations. Of the 70% of patients with a history of gout, only 30.8% were on ULT.

Discussion

Despite evidence-based recommendations for a 'treat-to-target' approach, most patients with a previous history of gout were not on ULT. One in five encounters were re-presentations for crystal arthropathy. Effective adherence to treatment guidelines may reduce the number of repeat encounters for gout flare in the ED.

Development and usability of a web-based patient-tailored tool to support adherence to urate-lowering therapy in gout

BACKGROUND

The aim of this study is to develop and assess usability of a web-based patient-tailored tool to support adherence to urate-lowering therapy (ULT) among gout patients in a clinical setting.

METHODS

The content of the tool was based on the Integrated Change (I-Change) model. This model combines various socio-cognitive theories and assumes behavioral change is a result of becoming aware of the necessity of change by integrating pre-motivational, motivational, and post-motivational factors. An expert group (five gout experts, three health services researchers, and one health behavior expert) was assembled that decided in three meetings on the tool's specific content (assessments and personalized feedback) using information from preparatory qualitative studies and literature reviews. Usability was tested by a think aloud approach and validated usability questionnaires.

RESULTS

The I-Change Gout tool contains three consecutive sessions comprising 80 questions, 66 tailored textual feedback messages, and 40 tailored animated videos. Navigation through the sessions was determined by the patients' intention to adapt suboptimal ULT adherence. After the sessions, patients receive an overview of the personalized advices and plans to support ULT adherence. Usability testing among 20 gout patients that (ever) used ULT and seven healthcare professionals revealed an overall score for the tool of 8.4 ± 0.9 and 7.7 ± 1.0 (scale 1-10). Furthermore, participants reported a high intention to use and/or recommend the tool to others. Participants identified some issues for further improvement (e.g. redundant questions, technical issues, and text readability). If relevant, these were subsequently implemented in the I-Change Gout tool, to allow further testing among the following participants.

CONCLUSION

This study provides initial support for the usability by patients and healthcare professionals of the I-Change Gout tool to support ULT adherence behavior.

Professionals' perspectives on existing practice and conditions for nurse-led gout care based on treatment recommendations: a qualitative study in primary healthcare

BACKGROUND

Gout affects nearly 2 % of the population and is associated with repeated painful flares of arthritis. Preventive urate-lowering therapy is widely available, but only one third of patients receive adequate treatment. Lack of knowledge among healthcare professionals and patients within primary healthcare are implicated as partial explanations for this undertreatment. Nurse-led care has proved to be an effective model when treating patients with gout, but there is a need for more knowledge about factors that can be expected to influence the future implementation of such care. The aim of this study was to describe factors influencing existing gout care in primary healthcare and the conditions for a future implementation of nurse-led gout care based on national treatment recommendations.

METHODS

In this qualitative study, focus group discussions with 56 nurses and physicians and individual interviews with eight managers were conducted at nine primary healthcare units in central Sweden. A deductive qualitative content analysis based on the main constructs of the framework Integrated Promoting Action on Research Implementation in Health Services was followed by an inductive analysis within the frames of the main constructs: innovation, recipients and context.

RESULTS

Gout-related contacts with primary healthcare was described as being patient initiated, diagnostics was in some respects complex and nurse-led care was experienced as a favourable primary healthcare model in general (innovation). Gout was seen as a low-priority condition with acute flares and there was inadequate knowledge of gout, including preventive treatment (recipients). Primary healthcare was perceived as having a holistic but fragmented responsibility for gout care, recommendations against keeping waiting lists complicated follow-up appointments and a need for motivation and support when introducing new practices was emphasised (context).

CONCLUSION

In this study, investigating the perspective of professionals, several factors were found to influence existing gout care. It will be crucial to target these factors in the development of a future implementation strategy.

Development of a patient decision aid for the initiation of urate-lowering therapy in gout patients

Aim

Shared decision-making improves patients’ experiences with care, satisfaction with management decisions and possibly health outcomes. This study describes the development of a decision aid (DA) that supports patients with gout and their physicians in a face-to-face clinical setting to (a) decide whether or not to (re)start urate-lowering therapy (ULT) and (b) agree on the preferred ULT.

Methods

Recommendations of the International Patient Decision Aid Standards group guided the development. A steering group of experts in gout and health services research specified the scope. Nominal group technique meetings were organised in which patients ranked the importance of preidentified potential characteristics/attributes of ULT and discussed further needs regarding the DA. A literature search was conducted to collect evidence on gout outcomes with and without ULT. Subsequently, the DA prototype was designed and adjusted using feedback from the steering group and results of cognitive debriefing interviews among five gout patients.

Results

The final DA consists of six pages. First, the DA clarifies the decision at stake and describes gout including its risk factors, the role of lifestyle and treatment of flares. Next, risk of future flares with and without ULT in relation to serum uric acid levels is described and visualised. Relevant attributes of ULT are presented in an option grid distinguishing first-line and second-line ULT. Finally, patients’ believes and preferences are explicitly addressed before making the shared decision.

Conclusion

This study provides initial support for usability of a DA for gout patients eligible for starting ULT.

Illness perception and treatment experience in patients with gout: a descriptive qualitative study

OBJECTIVE

To explore the illness perception and treatment experience of gout patients in China.

METHODS

A descriptive qualitative approach was used. In-depth semi-structured individual interviews were conducted among 18 adults with gout between August 2020 and December 2020. The Common-Sense Model of Self-Regulation was used as the conceptual framework for developing interview guide and data analysis. Interviews were audio recorded, transcribed, independently coded, and analyzed for themes.

RESULTS

The 18 gout patients aged 23-77 years old, with 16 being male. Four themes were generated to reflect the experience of patients with gout: limited knowledge of gout, various but inadequate sources of gout knowledge, multifaceted influences of gout, and seeking for diversified disease treatment methods.

CONCLUSION

There is a gap between patients' anticipation and practical service that is closely linked with subsequent poor gout management among the participants. The findings indicate a need of strengthening health education about gout by considering building nurse-led support groups and developing mobile health applications, as well as addressing the long-term influence of the Chinese alcoholic drinking culture to promote patients' effective disease management.

KEY POINTS

• This qualitative study fills a knowledge gap on illness perception and treatment experience among Chinese gout patients, exploring how these patients perceived gout and manage gout. • The gout patients in this study reported disparity between personal anticipation and healthcare service that largely contributes to their poor gout management. • The Chinese alcoholic drinking culture embedded in personal, professional, and social activities posed extra difficulties and challenges on modifying lifestyle for gout patients that needs to be addressed for promoting gout management among this group.

Potential Development of a Mobile Application for Gout Self-Management: What Support Do Patients Need?

PURPOSE

With the increasing prevalence and chronic course of gout, the use of mobile health (mHealth) applications (APPs) for gout self-management is attracting considerable research attention as an effective approach to improving health outcomes. However, there is limited knowledge regarding the self-management support that a mHealth APP for gout should provide to patients according to their needs. The aim of this study was to interview patients with gout and identify their needs with respect to gout self-management support.

PATIENTS AND METHODS

We conducted qualitative research using a purposive sampling method from January 2019 to August 2019. Individual face-to-face semi-structured interviews were conducted with patients recruited from West China Hospital in Sichuan, China. The qualitative data were transcribed verbatim and analyzed by thematic analysis.

RESULTS

Ten male patients with gout were included in the final analysis. Instrumental, psychological, and relational support emerged as themes describing the needs of patients for gout self-management support. The instrumental support included health education, hospital registration, setting reminders, and shopping. Psychological support referred to helping patients mitigate various negative emotions. Relational support included interactions with healthcare providers and fellow patients.

CONCLUSION

The present findings indicate that healthcare providers or companies should develop mHealth APPs for gout self-management based on the needs of patients.

Incorporating gout guideline advice into urate reports is associated with reduced hospital admissions: results of an observational study

OBJECTIVES

To evaluate the impact of incorporating treatment guidance into reporting of urate test results.

METHODS

Urate targets for clinically confirmed gout were added to urate results above 0.36 mmol/l requested after September 2014 within NHS Lothian. Scotland-wide data on urate-lowering therapy prescriptions and hospital admissions with gout were analysed between 2009 and 2020. Local data on urate tests were analysed between 2014 and 2015.

RESULTS

Admissions with a primary diagnosis of gout in Lothian reduced modestly following the intervention from 111/year in 2010-2014-104/year in 2015-2019, a non-significant difference (p= 0.32). In contrast there was a significant increase in admissions to remaining NHS Scotland health boards (556/year vs 606/year, p< 0.01). For a secondary diagnosis of gout the number of admissions in NHS Lothian reduced significantly (58/year vs 39/year, p< 0.01) contrasting with a significant increase in remaining Scottish health boards (220/year vs 290/year, p< 0.01). The relative rate of admissions to NHS Lothian compared with remaining Scottish boards using a 2009 baseline were significantly reduced for both primary diagnosis of gout (1.06 vs 1.25, p< 0.001) and secondary diagnoses of gout (0.64 compared with 1.4, p< 0.001) after the intervention; however, there was no difference before the intervention. A relative increase in the prescription rates of allopurinol 300 mg tablets and febuxostat 120 mg tablets may have contributed to the improved outcomes seen.

CONCLUSION

Incorporation of clinical guideline advice into routine reporting of urate results was associated with reduced rates of admission with gout in NHS Lothian, in comparison to other Scottish health boards.

'It's just a great muddle when it comes to food': a qualitative exploration of patient decision-making around diet and gout

Objective

Our aim was to understand whether, why and how patients choose to modify their diets after developing gout.

Methods

We conducted an inductive thematic secondary analysis of qualitative data from 43 interviews and four focus groups with UK participants with gout (n = 61).

Results

Participants commonly initiated dietary changes as part of a self-management strategy for gout. Reasons for making such dietary changes included: desperation; a desire for control; and belief that it would be possible to achieve successful management through diet alone; but not weight loss. Participants who did not make changes or who reverted to previous dietary patterns did so because: they believed urate-lowering therapy was successfully managing their gout; medication allowed normal eating; they did not find ‘proof’ that diet would be an effective treatment; or the dietary advice they found was unrealistic, unmanageable or irrelevant. Dietary modification was patient led, but patients would have preferred the support of a health-care professional. Beliefs that diet could potentially explain and modify the timing of flares gave patients a sense of control over the condition. However, the belief that gout could be controlled through dietary modification appeared to be a barrier to acceptance of management with urate-lowering therapy.

Conclusions

Perceptions about gout and diet play a large role in the way patients make decisions about how to manage gout in their everyday lives. Addressing the reasons why patients explore dietary solutions, promoting the value of urate-lowering therapy and weight loss and drawing on strong evidence to communicate clearly will be crucial in improving long-term clinical management and patient experience.

Outcomes of Care Among Patients With Gout in Europe: A Cross-sectional Survey

OBJECTIVE

To assess health- and patient-centered outcomes in gout across Europe, and explore patient-, care-, and country-level characteristics associated with these outcomes.

METHODS

Patients with self-reported physician-diagnosed gout from 14 European countries completed an online survey. Multivariable mixed-effect logistic and linear regressions were computed for health outcomes (gout flare recurrence) and patient-centered outcomes (patient satisfaction with current medication, and unaddressed goals), accounting for clustering within countries. The role of patient-, care-, and country-level factors was explored.

RESULTS

Participants included 1029 patients, predominantly diagnosed by a general practitioner (GP). One or more gout flares were reported by 70% of patients and ≥ 3 flares by 32%. Gout patients reported 1.1 ± 1.2 unaddressed goals, and 80% were satisfied with current medication. Patients with ≥ 3 and ≥ 1 flares were less likely to be treated with urate-lowering therapy (ULT) (OR 0.52, 95% CI 0.39-0.70 and OR 0.38, 95% CI 0.28-0.53, respectively), but more likely to have regular physician visits (OR 2.40, 95% CI 1.79-3.22 and OR 1.77, 95% CI 1.30-2.41). Three or more gout flares were also associated with lower satisfaction (OR 0.39, 95% CI 0.28-0.56) and more unaddressed goals (β 0.36, 95% CI 0.19-0.53). Notwithstanding, the predicted probability of being satisfied was still between 57% and 75% among patients with ≥ 3 flares but who were not receiving ULT. Finally, patients from wealthier and Northern European countries more frequently had ≥ 3 gout flares.

CONCLUSION

Across Europe, many patients with gout remain untreated despite frequent reported flares. Remarkably, a substantial proportion of them were still satisfied with gout management. A better understanding of patients' satisfaction and its role in physicians' gout management decisions is warranted to improve quality of care and gout outcomes across Europe.

Patient-Centered Outcomes and Key Study Procedure Finalization in the Pilot Feasibility Gout Randomized Trial: Comparative Feasibility Study in GOUt, CHerry Extract Versus Diet Modification (Mini-GOUCH)

OBJECTIVE

The aim of this study was to report patient-centered outcomes and finalization of key study procedures from a 9-month pilot internet randomized controlled trial of cherry extract versus diet modification.

METHODS

We randomized 84 people with physician-confirmed gout in an internet study to cherry extract (n = 41) or dietitian-assisted diet modification for gout (n = 43). All study outcomes were collected via internet and phone calls. We finalized key study procedures. We assessed acceptability and feasibility of the intervention and satisfaction with study website.

RESULTS

Study participant satisfaction with the intervention was high. The intervention was perceived as easy, enjoyable, understandable, and helpful (scores 65-88 for all; higher = better). The amount of time spent for the study was acceptable. Participant satisfaction with website interaction and content was very high; 85% or more were moderately to extremely satisfied. Significantly lower total calories, total carbohydrate, and saturated fat intake were noted at 6 months in the diet modification versus cherry extract group; differences were insignificant at 9 months. Six of the 8 Health Assessment Questionnaire sections/domains improved significantly from baseline to 9 months in cherry extract versus 2 Health Assessment Questionnaire sections/domains in the diet modification group. Key study procedures were finalized for a future trial, including an internet diet assessment tool, gout flare assessment, provider confirmation of gout diagnosis, patient reporting of classification criteria, and centralized laboratory-assisted serum urate testing.

CONCLUSIONS

High patient acceptability and feasibility of study/intervention and finalization of key study procedures indicate that hypothesis-testing internet gout trials of cherry extract and/or diet modification can be conducted in the future.

Gout

Gout is a common and treatable disease caused by the deposition of monosodium urate crystals in articular and non-articular structures. Increased concentration of serum urate (hyperuricaemia) is the most important risk factor for the development of gout. Serum urate is regulated by urate transporters in the kidney and gut, particularly GLUT9 (SLC2A9), URAT1 (SLC22A12), and ABCG2. Activation of the NLRP3 inflammasome by monosodium urate crystals with release of IL-1β plays a major role in the initiation of the gout flare; aggregated neutrophil extracellular traps are important in the resolution phase. Although presenting as an intermittent flaring condition, gout is a chronic disease. Long-term urate lowering therapy (eg, allopurinol) leads to the dissolution of monosodium urate crystals, ultimately resulting in the prevention of gout flares and tophi and in improved quality of life. Strategies such as nurse-led care are effective in delivering high-quality gout care and lead to major improvements in patient outcomes.

Development of a novel gout treatment patient decision aid by patient and physician: A qualitative research study

BACKGROUND

Gout treatment is not optimized globally, often due to therapeutic inertia by physicians or poor adherence to urate-lowering medications by patients. A patient decision aid (PDA) to facilitate shared decision making (SDM) in gout treatment may overcome these physician-patient barriers.

OBJECTIVE

The study explored the views of physicians and patients on a novel locally designed gout treatment PDA prototype.

DESIGN

Qualitative descriptive design was used to gather data from in-depth-interviews (IDI) and focus group discussions (FGD). Data analysis was via thematic analysis. Emergent themes shaped a revised version of the PDA.

SETTING AND PARTICIPANTS

Adult Asian patients with recent acute gout exacerbations and local Primary Care Physicians (PCP) in Singapore were purposefully chosen. 15 patients with gout and 11 PCPs participated across three IDIs and six FGDs, with the investigators exploring their views of a prototype gout treatment PDA.

RESULTS

Patients and physicians generally concurred with the content and design of the PDA prototype. However, while patients preferred fewer treatment details, the PCPs desired more information. Patients preferred the display of statistics, while PCPs felt that numbers were not relevant to patients. The latter were hesitant to include treatment options that were unavailable in primary care. Both stakeholders indicated that they would use the PDA during a consultation. PCPs would need further training in SDM, given a lack of understanding of it.

CONCLUSION AND PATIENT CONTRIBUTION

Patients will be the prime users of the PDA. While their views differed partially from the physicians, both have jointly developed the novel gout treatment PDA.

Qualitative Research in Rheumatology: An Overview of Methods and Contributions to Practice and Policy

Patient-centered care is widely advocated in rheumatology. This involves collaboration among patients, caregivers, and health professionals and is particularly important in chronic rheumatic conditions because the disease and treatment can impair patients' health and well-being. Qualitative research can systematically generate insights about people's experiences, beliefs, and attitudes, which patients may not always express in clinical settings. These insights can address complex and challenging areas in rheumatology, such as treatment adherence and transition to adult healthcare services. Despite this, qualitative research comprises 1% of studies published in top-tier rheumatology journals. A better understanding about the effect and role, methods, and rigor of qualitative research is needed. This overview highlights the recent contributions of qualitative research in rheumatology, summarizes the common approaches and methods used, and outlines the key principles to guide appraisal of qualitative studies.

Review of gout clinic in a tertiary hospital setting

Although updated consensus guidelines, and effective therapies, are available for management of gout, suboptimal management remains an issue. Barriers were identified and addressed as part of a dedicated, structured gout clinic. More frequent appointments resulted in a faster rate of serum urate reduction, and the clinic provided the opportunity for the education of both patients and general practitioners in the management of gout.

Diagnosis and management of gout by clinicians in Nepal: a web-based survey

Patients with gout in Nepal are usually attended by medical graduates, family medicine, internists, and orthopedic surgeons. The study aimed to evaluate knowledge, attitude, and practice (KAP) of point-of-care clinicians of Nepal regarding diagnosis and management of gout and assess the quality of treatment provided to the patients. A web-based descriptive, cross-sectional study was conducted among doctors managing gout patients. The questionnaire comprises 38 multiple choice questions; 9 questions for demographic data, 8, 11, and 10 questions each for knowledge, attitude, and practice, respectively. A pilot study was conducted to observe comprehensibility of the questionnaire before subjecting it to the participants. Ethical approval was obtained from review committee of National Center for Rheumatic diseases, Nepal. Simple descriptive statistics was used to describe the correct responses. Among 1200 clinicians invited, 32% (380) participated in the survey. Maximum respondents were of age group 25-45 years (82%) with majority being internists (43%). Although only 32% understood that the disease is not curable, knowledge regarding disease was acceptable in majority (60-90%). Around 83% denied attending any gout-related seminars and 34% denied being updated with the recent guidelines. The majority of postgraduates (72%) managed the cases themselves. Although there was acceptable practice accuracy on use of therapy for acute attacks (75%), target urate levels (57%), and use of urate-lowering agents (92%), they lacked in adequate screening of co-morbidities and initiation of long-term treatment. The point-of-care clinicians have adequate knowledge to diagnose and treat acute events. However, there is poor reflection in practice and frequent update of treatment guidelines is warranted.

2020 recommendations from the French Society of Rheumatology for the management of gout: Urate-lowering therapy

OBJECTIVE

To develop French Society of Rheumatology-endorsed recommendations for the management of urate-lowering therapy (ULT).

METHODS

Evidence-based recommendations were developed by 9 rheumatologists (academic or community-based), 3 general practitioners, 1 cardiologist, 1 nephrologist and 1 patient, using a systematic literature search, one physical meeting to draft recommendations and two Delphi rounds to finalize them.

RESULTS

A set of 3 overarching principles and 5 recommendations was elaborated. The overarching principles emphasize the importance of patient education, especially the need for explaining the objective of lowering serum urate (SU) level to obtain crystal dissolution, clinical symptoms disappearance and avoidance of complications. ULT is indicated as soon as the diagnosis of gout is established. SU level must be decreased below 300μmol/l (50mg/l) in all gout patients or at least below 360μmol/l (60ml/l) when the 300μmol/l target cannot be reached, and must be maintained at these targets and monitored life-long. The choice of the ULT primarily relies on renal function: in patients whose estimated glomerular filtration rate (eGFR) is above 60ml/min/1.73m², first-line ULT is allopurinol; in those with eGFR between 30 and 60ml/min/1.73m², allopurinol use must be cautious and febuxostat can be considered as an alternative; and in those whose eGFR is below 30ml/min/1.73m², allopurinol must be avoided and febuxostat should be preferred. Prophylaxis of ULT-induced gout flares involves progressive increase of ULT dosage and low-dose colchicine for at least 6 months. Cardiovascular risk factors and diseases, the metabolic syndrome and chronic kidney disease must be screened and managed.

CONCLUSION

These recommendations aim to provide simple and clear guidance for the management of ULT in France.

The impact of the illness label 'gout' on illness and treatment perceptions in Māori (Indigenous New Zealanders)

Background

Despite contemporary advances in understanding pathogenesis and effective management of gout, beliefs about the disease continue to be focused on gout as a self-inflicted illness. The illness label itself may contribute to inaccurate perceptions of the disease and its management. In Aotearoa/New Zealand, Māori (Indigenous New Zealanders) have high prevalence of severe gout. The aim of this study was to examine the impact of the illness label ‘gout’ on perceptions of the disease and its management for Māori.

Methods

Māori supermarket shoppers (n = 172) in rural and urban locations were recruited into a study examining the perceptions about arthritis. Participants were randomised 1:1 to complete a questionnaire examining the perceptions of the same illness description labelled as either ‘gout’ or ‘urate crystal arthritis’. Differences between the two illness labels were tested using independent sample t-tests.

Results

‘Gout’ was most likely to be viewed as caused by diet, whereas ‘urate crystal arthritis’ was most likely to be viewed as caused by aging. ‘Urate crystal arthritis’ was seen as having a wider range of factors responsible for the illness, including stress or worry, hereditary factors and chance. ‘Gout’ was less likely to be viewed as having a chronic timeline, and was perceived as being better understood. Dietary management strategies were seen as more helpful for management of the gout-labelled illness.

Conclusions

This study has demonstrated that for Māori, Indigenous New Zealanders who are disproportionately affected by gout, the illness label influences perceptions about gout and beliefs about management.

A thematic synthesis of siblings' lived experiences of autism: Distress, responsibilities, compassion and connection

BACKGROUND

Despite increased understandings that the whole family system is influenced by a family member being diagnosed with an Autism Spectrum Condition (ASC), the experiences of siblings can be overlooked. However, recently understanding of siblings' experiences has begun to develop via qualitative studies.

AIMS

This review aimed to systematically identify, appraise and review the qualitative literature investigating the lived experience of siblings of autistic people.

METHODS AND PROCEDURES

Six databases were systematically searched for studies reporting empirical qualitative data on the lived experience of neurotypical siblings of autistic people. Eighteen studies met inclusion criteria and were analysed using Thematic Synthesis.

OUTCOMES AND RESULTS

Data synthesis revealed four superordinate themes; Roles and responsibilities, different to what may be expected typically; Impact of behaviours, particularly aggressive behaviours; Process of adjustment, including learning and developing empathy and acceptance; Interpersonal experiences with others and between siblings.

CONCLUSIONS AND IMPLICATIONS

A narrative of love and empathy was present throughout. However, several participants also experienced significant difficulties affecting their mental health. Findings suggest a sense of agency, understanding ASC, time spent alone with parents, supportive environments and the chance to relate to other siblings as protective factors in facilitating positive psychological wellbeing for siblings of autistic people.

What factors contribute to uncontrolled gout and hospital admission? A qualitative study of inpatients and their primary care practitioners

OBJECTIVE

To provide deeper insight into why patients are admitted to hospital with gout and discover potential targets for better disease control.

DESIGN

Data from semi-structured interviews were analysed using a thematic analysis approach.

PARTICIPANTS AND SETTING

Eleven inpatients from a tertiary institution in the Australian Capital Territory of Australia and their respective general practitioners (GPs) were invited to participate in the semi-structured interviews.

RESULTS

Despite significant pain and disability that accompanied acute flares, patients continue to experience shame in seeking treatment and regarded gout as being not particularly important. Other barriers included patients' poor continuity of care with and lack of confidence in GPs, suboptimal management in outpatient and inpatient settings, poor understanding of disease and treatment, and misconceptions held by both patients and physicians leading to uncontrolled disease activity.

CONCLUSIONS

Barriers to optimal gout management including patient and health practitioner factors have produced a complex effect which has led to a cycle of treatment avoidance behaviours and recurrent hospitalisations for severe acute gout flares. These barriers could be addressed using a multipronged approach guided by the chronic care model which has been applied in a variety of other chronic diseases with improved patient and professional-level outcomes. Managing gout according to best practice for chronic disease is more likely to prevent recurrent hospitalisations and improve health outcomes in patients with gout.

Making the right thing the easy thing to do: strategies to improve outcomes in gout

The burden of gout is increasing worldwide. Although urate-lower ing drugs have been available for more than half a century, the initiation and persistence of urate-lowering therapy remain low. Health-care system, practitioner, and patient barriers contribute to the clinical inertia in gout management. Pervasive beliefs about gout as a disease of an indulgent lifestyle that should be managed primarily with dietary modification are key barriers that prevent patients from receiving effective therapy. In light of safety concerns about newer urate-lowering medications, allopurinol, an inexpensive generic medication, is likely to remain the first-line urate-lowering therapy for the foreseeable future. Ensuring that allopurinol is optimally and persistently prescribed is a priority for improved gout management. A health literacy approach that focuses on patient understanding of gout as a chronic disease that requires behaviour change to take long term urate-lowering therapy is important. This approach provides a clear rationale for long-term urate-lowering therapy that is able to dissolve the monosodium urate crystals and ultimately prevent the symptoms of gout. Patient-centred models that use the skills of nurses and pharmacists to facilitate patient understanding can lead to major improvements in gout care. Additionally, systematic quality improvement approaches within practices, while reducing inconvenience and cost to patients, should be a priority.

Gout

Gout is a chronic disease caused by monosodium urate (MSU) crystal deposition. Gout typically presents as an acute, self-limiting inflammatory monoarthritis that affects the joints of the lower limb. Elevated serum urate level (hyperuricaemia) is the major risk factor for MSU crystal deposition and development of gout. Although traditionally considered a disorder of purine metabolism, altered urate transport, both in the gut and the kidneys, has a key role in the pathogenesis of hyperuricaemia. Anti-inflammatory agents, such corticosteroids, NSAIDs and colchicine, are widely used for the treatment of gout flare; recognition of the importance of NLRP3 inflammasome activation and bioactive IL-1β release in initiation of the gout flare has led to the development of anti-IL-1β biological therapy for gout flares. Sustained reduction in serum urate levels using urate-lowering therapy is vital in the long-term management of gout, which aims to dissolve MSU crystals, suppress gout flares and resolve tophi. Allopurinol is the first-line urate-lowering therapy and should be started at a low dose, with gradual dose escalation. Low-dose anti-inflammatory therapies can reduce gout flares during initiation of urate-lowering therapy. Models of care, such as nurse-led strategies that focus on patient engagement and education, substantially improve clinical outcomes and now represent best practice for gout management.

Partners and nurses' knowledge and representations of gout: A qualitative study

Adherence to gout treatment is poor. Partners of patients and nurses are two major communicators with gouty patients, and their perceptions of illness may affect patient behavior.

OBJECTIVE

To explore partners' and nurses' knowledge and representations of gout.

METHODS

We used a qualitative grounded approach with semi-structured face-to-face individual interviews with a purposive sample of hospital nurses working in rheumatology and internal medicine departments and patient partners. Interviews were audio-recorded and transcribed. All authors met regularly to discuss coding and data interpretation.

RESULTS

Overall, 20 nurses and 12 partners participated in the interviews. Four major themes were evidenced: knowledge gaps (gout cause was unknown, unawareness of urate-lowering therapy and the possibility to cure gout, focus in gout flare and diet); lack of information and education on gout (knowledge acquired by personal experiences, nurses complained to be insufficiently educated, partners highlighted the lack of information and that general practitioners did not have time to educate patients); gout consequences and social impacts (handicapping disease, avoid social activities like dinner with friends); attitudes towards gout flare and patient management (feeling powerless during flare, negative feelings such as being ashamed leading to postpone medical seek or unconcerned about their partner disease). Nurses regretted that they had not enough time to discuss issues with patients.

CONCLUSION

Partners and nurses' knowledge of gout is based on daily experiences. Participants were eager to learn more about gout. Nurses' education and education programs including partners may improve gout management and patient adherence to treatment.
