Gout in primary care: Can we improve patient outcomes?

Determinants of Self-Management Behavior in Gout: A Scoping Review

OBJECTIVE

This study aimed to identify modifiable determinants of self-management behavior in patients with gout.

METHODS

Four databases (Medline, Embase, PsycINFO, and CINAHL) were searched using terms related to gout, self-management, and determinants of behavior as described in the Theoretical Domains Framework (TDF). Two reviewers independently selected relevant studies via screening of title/abstract and full text. Thematic synthesis was performed for qualitative data; quantitative data were summarized using cross-tabulation displaying the investigated associations of determinants with self-management behavior. The TDF facilitated identification and grouping of determinants.

RESULTS

From 2,087 unique articles found, 56 studies were included in this review, of which there were 27 qualitative and 29 quantitative studies. Eight themes were identified: knowledge and skills for self-management, acceptance of disease, beliefs about necessity of self-management to improve gout-related health, resistance and reluctance for medication adherence and dietary alteration/changes, negative emotions influencing self-management, social support and interactions, environmental context, and self-regulation of behavior. Quantitative determinants associated with self-management behavior, predominantly medication adherence, were mapped to 12 of the 14 domains of the TDF. No determinants regarding skills and goals have been identified in quantitative research.

CONCLUSION

Intervention targets for self-management behavior in patients with gout mainly included determinants related to knowledge, implicit and explicit beliefs and attitudes, the environmental context and resources, and (social) support and reinforcement.

Gender and Ethnic Inequities in Gout Burden and Management

Although effective and low-cost urate-lowering therapy has been available for decades, inequities in gout management exist. Despite high impact of disease, rates of urate-lowering therapy prescription are low in women, in African-Americans in the United States, in Māori (Indigenous New Zealanders), and in Pacific peoples living in Aotearoa/New Zealand. Social determinants of health, barriers to accessing the health care system, health literacy demands, stigmatization, and bias contribute to inequities in gout burden and management. Approaches that focus on building health literacy and delivering culturally safe care lead to improved outcomes in gout, and offer important solutions to achieve health equity.

Interventions to improve uptake of urate-lowering therapy in patients with gout: a systematic review

BACKGROUND

Gout treatment is suboptimal despite available therapy, with low levels of initiation and persistence of urate-lowering therapy (ULT) in many patients.

AIM

To identify all interventions that have attempted to improve the uptake of ULT and analyse the clinical outcomes.

DESIGN & SETTING

A systematic review of international articles published in English.

METHOD

A systematic search was conducted through MEDLINE, Embase, CINAHL Plus, and Scopus databases to identify all studies on relevant interventions for gout. Interventions were included if they aimed to address patient adherence with serum urate (SU) level as an outcome. This included patient education, practitioner monitoring, medication titration, SU monitoring, and ongoing patient engagement and follow-up. Follow-up studies to original interventions and those with only an abstract available were included.

RESULTS

Twenty articles met the inclusion criteria, describing outcomes of 18 interventions conducted in primary care settings: six nurse-led, five pharmacist-led, and seven multidisciplinary, multifaceted interventions. Improvement in SU levels was observed in all interventions. Nurse-led interventions were effective at empowering patients as they addressed illness perceptions and provided education, advice, and telephone follow-up. Pharmacist-led interventions primarily aimed to monitor patients, alter medication dosage, and provide automated telephone follow-up. Various multifaceted programmes involving a range of providers resulted in increased sustained use of urate-lowering medication.

CONCLUSION

A nurse-led approach focusing on patient understanding about gout is the most effective in achieving improved patient adherence, and lowered SU levels among patients. An intervention should include patient education and follow-up components.

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.
