Scabies

Scabies is one of the most common and highest-burden skin diseases globally. Estimates suggest that >200 million people worldwide have scabies at any one time, with an annual prevalence of 455 million people, with children in impoverished and overcrowded settings being the most affected. Scabies infection is highly contagious and leads to considerable morbidity. Secondary bacterial infections are common and can cause severe health complications, including sepsis or necrotizing soft-tissue infection, renal damage and rheumatic heart disease. There is no vaccine or preventive treatment against scabies and, for the past 30 years, only few broad-spectrum antiparasitic drugs (mainly topical permethrin and oral ivermectin) have been widely available. Treatment failure is common because drugs have short half-lives and do not kill all developmental stages of the scabies parasite. At least two consecutive treatments are needed, which is difficult to achieve in resource-poor and itinerant populations. Another key issue is the lack of a practical, rapid, cheap and accurate diagnostic tool for the timely detection of scabies, which could prevent the cycle of exacerbation and disease persistence in communities. Scabies control will require a multifaceted approach, aided by improved diagnostics and surveillance, new treatments, and increased public awareness.

Quality of life among adults with scabies: A community-based cross-sectional study in north-western Ethiopia

INTRODUCTION

Scabies undermines quality of life through its highly disturbing disease symptoms, by distorting self-perception, and secondary to social stigma. Knowledge of its effect on quality of life in general and on specific aspects of day-to-day life is key to addressing the health needs of individual patients and to evaluating gains from community-based disease control interventions.

OBJECTIVES

To measure the effect of scabies on the quality of life of people with the infestation.

METHODS

A community-based cross-sectional study was conducted in a scabies outbreak-affected district in north-western Ethiopia. The study involved 381 households and 86 adults with scabies. We used the ten-item Cardiff Dermatology Life Quality Index (DLQI) tool to collect data. Cronbach's alpha value was used to determine the internal consistency of the Amharic version of the scale. Overall and Dermatology Life Quality (DLQ) domain specific mean scores were calculated. The association between sociodemographic characteristics and scabies-related life quality impairment was tested using Kruskal-Wallis test.

RESULTS

Scabies moderately affected the quality of life of adults with scabies. The overall mean DLQI (mDLQI) score was 9.2 (SD = 7.6). 'Symptoms and feelings' and 'daily activity' DLQ domains had the highest mDLQI scores (3.5, SD = 1.9 and 2.2, SD = 2.5, respectively). 'Leisure activities' was the least affected domain 0.8 (SD = 1.1). In terms of severity, scabies had moderate or severe effect on DLQ of 54.7% of the participants and extremely severe effect was reported among 27% of the participants. However, no association was observed between sociodemographic characteristics and quality of life impairment.

CONCLUSION

Quality of life was moderately impaired among people affected by scabies. Refocusing attention on management of disease symptoms, using standard scabies treatment, and providing psychosocial support to improve self-perception of people affected with scabies may help reduce quality of life impairment.

Conceptualising retention in treatment with long-acting injectable buprenorphine (for opioid use disorder) as a journey: Findings from a longitudinal qualitative study

BACKGROUND

Conceptualisations of the 'patient journey' are popular within health service research. Patient journeys provide a person-centred approach to health care that typically prioritise subjective patient experience with the aim of improving relevant forms of intervention. This article explores the conceptualisation of retention in treatment for opioid use disorder (OUD) using long-acting injectable buprenorphine (LAIB) as a journey.

METHODS

Data derive from a longitudinal qualitative study, involving semi-structured interviews (held at six time-points), with participants who each initiated LAIB for the first time. Data analysis for this article focuses exclusively upon the experiences of those who had continued with LAIB treatment throughout one year (11 participants). Framework and thematic narrative analyses of 64 interviews with 11 participants sought to identify 'retention-narratives' that would indicate a 'retention journey' associated with LAIB treatment.

FINDINGS

Shared treatment experiences consisted of three distinct phases (Withdrawal and Separation, Transformation, and Engagement) that progressed in a linear and intersecting manner through time. Each phase had features that defined treatment experiences at a given time but changed as treatment progressed. All 11 participants experienced multiple features within each of the three treatment phases and all participants reported separation from their respective service provider throughout the first 12 months of treatment. Although some valued the latter separation, most were dissatisfied by reduced levels of contact.

CONCLUSION

Retention in treatment for OUD with LAIB, for at least 12-months, can be conceptualised as a journey. This conceptualisation emphasises the benefits (and challenges) clinicians and patients may expect to encounter during the first year of a LAIB treatment programme. An added implication of conceptualising LAIB treatment in this manner is that optimal benefits of the medication (as observed by participants) began to emerge during 'months 7-12' of the retention journey.

Scabies outbreak management in refugee/migrant camps in Europe 2014-2017: a retrospective qualitative interview study of healthcare staff experiences and perspectives

OBJECTIVES

Provide insights into the experiences and perspectives of healthcare staff who treated scabies or managed outbreaks in formal and informal refugee/migrant camps in Europe 2014-2017.

DESIGN

Retrospective qualitative study using semistructured telephone interviews and framework analysis. Recruitment was done primarily through online networks of healthcare staff involved in medical care in refugee/migrant settings.

SETTING

Formal and informal refugee/migrant camps in Europe 2014-2017.

PARTICIPANTS

Twelve participants (four doctors, four nurses, three allied health workers, one medical student) who had worked in camps (six in informal camps, nine in formal ones) across 15 locations within seven European countries (Greece, Serbia, Macedonia, Turkey, France, the Netherlands, Belgium).

RESULTS

Participants reported that in camps they had worked, scabies diagnosis was primarily clinical (without dermatoscopy), and treatment and outbreak management varied highly. Seven stated scabicides were provided, while five reported that only symptomatic management was offered. They described camps as difficult places to work, with poor living standards for residents. Key perceived barriers to scabies control were (1) lack of water, sanitation and hygiene, specifically: absent/limited showers (difficult to wash off topical scabicides), and inability to wash clothes and bedding (may have increased transmission/reinfestation); (2) social factors: language, stigma, treatment non-compliance and mobility (interfering with contact tracing and follow-up treatments); (3) healthcare factors: scabicide shortages and diversity, lack of examination privacy and staff inexperience; (4) organisational factors: overcrowding, ineffective interorganisational coordination, and lack of support and maltreatment by state authorities (eg, not providing basic facilities, obstruction of self-care by camp residents and non-governmental organisation (NGO) aid).

CONCLUSIONS

We recommend development of accessible scabies guidelines for camps, use of consensus diagnostic criteria and oral ivermectin mass treatments. In addition, as much of the work described was by small, volunteer-staffed NGOs, we in the wider healthcare community should reflect how to better support such initiatives and those they serve.

Scabies in the Amhara region of northern Ethiopia: a cross-sectional study of prevalence, determinants, clinical presentation and community knowledge

BACKGROUND

The WHO aims to prevent, eliminate or control neglected tropical diseases, including scabies, by 2030. However, limited epidemiological data presented a challenge to control efforts, especially in high burden countries. There was a major scabies outbreak in northern Ethiopia starting in 2015 and prevalence has since increased across much of the country.

OBJECTIVE

To estimate scabies prevalence, identify its predictors, and assess community perception of, and knowledge about, the infestation.

DESIGN

Population-based cross-sectional study.

STUDY SETTING

Ayu Guagusa district, Amhara region, northern Ethiopia.

PARTICIPANTS

1437 people who were members of 381 randomly selected households participated in the study. Five trained mid-level health workers clinically diagnosed people with scabies.

OUTCOME MEASURES

Clinically diagnosed scabies infestation.

DATA ANALYSIS

Multi-level logistic regression models were fitted to adjust for individual and household-level confounding variables, and identify predictors of scabies infestation.

RESULTS

Scabies prevalence was 13.4% (95% CI 11.8 to 15.5). Households of more than five people (adjusted OR (aOR)=3.5, 95% CI 1.2 to 10.2) were associated with increased odds of developing scabies, however, females had lower odds (aOR=0.5 95% CI 0.3 to 0.8). Scabietic lesions most frequently involved the trunk (62.0%), and vesicles were the most common types of lesions (67.7%). Two-thirds of adult study participants had heard about scabies and most obtained scabies related information from informal sources. Only 32% of cases sought care for scabies from any source.

CONCLUSION

Scabies prevalence was high, signifying the need for community-based control interventions. Host density and sex were important predictors of scabies. Despite the favourable attitude toward the effectiveness of scabies treatment, healthcare seeking was low.

A qualitative research study on the illness perception of chronic pruritus in older Asian adults based on the Common-Sense Model of self-regulation

Background

Chronic pruritus (CP), itch lasting more than 6 weeks, is common in community‐dwelling older adults. Understanding their illness perception allows the attending physician to develop a personalised care plan to mitigate CP.

Aim

This study explores the illness perception of CP among older Asian adults in an urban community.

Design

Qualitative research was conducted, framed by the Common‐Sense Model of self‐regulation (CSM). Through in‐depth interviews (IDIs), qualitative data were gathered from Asian patients with CP, and then a thematic analysis was carried out. The emergent themes were grouped according to the five domains of CSM: ‘identity’, ‘cause’, ‘time’, ‘controllability’ and ‘consequence’.

Setting and Patients

IDIs were conducted in a Singapore public primary care clinic before the data were saturated.

Results

The CSM domains illustrate the illness perception of CP. CP was identified as a ‘problem’ rather than a disease and was often described in metaphor. Patients' perception of the cause was diverse due to the lack of provision of a clear explanation by their physicians. They opined that CP continued indefinitely. Without definite time to resolution, patients adapted their help‐ and health‐seeking behaviours to control it. The consequences included therapeutic experimentation, alternative therapy, self‐isolation, avoidance behaviours, emotional disturbance and dermatological complications.

Conclusion and Patient Contribution

Patients provided information on their perception of CP, which aligned with the CSM. A multipronged approach is needed to deliver holistic and personalised care to patients with CP, providing clarity on its natural progression, to set their expectations on its timeline, treatment effectiveness and undertake appropriate behaviour modification to adapt to its chronicity.

Care and treatment needs of immunosuppressive therapy patients with warts and impact on everyday life: a qualitative study

INTRODUCTION

Patients receiving immunosuppressive therapy have an increased risk of developing verrucae vulgaris (warts). They often suffer from dissemination of numerous warts, complicated by low treatment response and long-term treatment. How patients experience these challenges is not well characterized. The aim of this study was to explore how patients on immunosuppressive therapy experience everyday life with warts on the hands and feet, and their needs related to care and treatment.

METHODS

The study took a phenomenological-hermeneutic approach. Semi-structured interviews were conducted with 10 adults. Data were analyzed using the thematic analysis described by Braun and Clark.

RESULTS

Warts on the hands and feet impact everyday life and cause feelings of stigma and pain. Patients request treatment and hope to be cured although the prospects are poor. Self-treatment is experienced as a burden, because of the need for more specific information about and skills to treat the warts, and because individual patients' resources are not considered. Patients experience a lack of care continuity.

CONCLUSIONS

Patients request a person-centred care and treatment approach, to establish a relationship with health care professionals. Establishing care continuity might reduce patients' treatment-related insecurity.
