Prioritizing treatment outcomes: How people with acne vulgaris decide if their treatment is working

Guidelines of care for the management of acne vulgaris

BACKGROUND

Acne vulgaris commonly affects adults, adolescents, and preadolescents aged 9 years or older.

OBJECTIVE

The objective of this study was to provide evidence-based recommendations for the management of acne.

METHODS

A work group conducted a systematic review and applied the Grading of Recommendations, Assessment, Development, and Evaluation approach for assessing the certainty of evidence and formulating and grading recommendations.

RESULTS

This guideline presents 18 evidence-based recommendations and 5 good practice statements. Strong recommendations are made for benzoyl peroxide, topical retinoids, topical antibiotics, and oral doxycycline. Oral isotretinoin is strongly recommended for acne that is severe, causing psychosocial burden or scarring, or failing standard oral or topical therapy. Conditional recommendations are made for topical clascoterone, salicylic acid, and azelaic acid, as well as for oral minocycline, sarecycline, combined oral contraceptive pills, and spironolactone. Combining topical therapies with multiple mechanisms of action, limiting systemic antibiotic use, combining systemic antibiotics with topical therapies, and adding intralesional corticosteroid injections for larger acne lesions are recommended as good practice statements.

LIMITATIONS

Analysis is based on the best available evidence at the time of the systematic review.

CONCLUSIONS

These guidelines provide evidence-based recommendations for the management of acne vulgaris.

Patient Perspectives on the Lived Experience of Acne and Its Treatment Among Adult Women With Acne: A Qualitative Study

Introduction

Acne often persists into adulthood in women. However, few studies have specifically explored the lived experience of acne in adult populations.

Objective

To examine the lived experience of acne and its treatment among a cohort of adult women.

Design, Setting, and Participants

A qualitative analysis was conducted from free listing and open-ended, semistructured interviews of patients at a large academic health care system (University of Pennsylvania Health System) and a private practice (Dermatologists of Southwest Ohio). Fifty women 18 to 40 years of age with moderate to severe acne participated in interviews conducted between August 30, 2019, and December 31, 2020.

Main Outcomes and Measures

Free-listing data from interviews were used to calculate the Smith S, a measure of saliency for each list item. Semistructured interviews were examined to detect themes about patient perspectives regarding their acne and its treatment.

Results

Fifty participants (mean [SD] age, 28 [5.38] years; 24 [48%] White) described acne-related concerns about their appearance that affected their social, professional, and personal lives, with many altering their behavior because of their acne. Depression, anxiety, and social isolation were commonly reported. Participants described successful treatment as having completely clear skin over time or a manageable number of blemishes. Many participants described frustration with finding a dermatologist with whom they were comfortable and with identifying effective treatments for their acne.

Conclusions and Relevance

The results of this qualitative study suggest that women with acne have strong concerns about appearance and experience mental and emotional health consequences and disruption of their personal and professional lives. In addition, many patients describe challenges finding effective treatments and accessing care. Future trials to understand the optimal treatment approaches for women with acne are needed to improve outcomes in this population.

Patient-reported outcome measures for acne: a mixed-methods validation study (acne PROMs)

OBJECTIVES

To examine the acceptability and validity of two patient-reported outcome measures (PROMs) for adult acne, comparing them to the validated Acne-specific Quality of Life (Acne-QoL) measure.

DESIGN

Mixed-methods validation study.

SETTING

Participants were recruited by (1) mail-out through primary care if they had ever consulted for acne and received a prescription for acne treatment within the last 6 months, (2) opportunistically in secondary care and (3) poster advertisement in community venues.

PARTICIPANTS

221 (204 quantitative and 17 qualitative) participants with acne, aged 18-50 years.

OUTCOME MEASURES

Quantitative sub-study participants completed Acne-QoL, Skindex-16 and Comprehensive Acne Quality of Life Scale (CompAQ) at baseline, 24 hours and 6 weeks. Qualitative sub-study participants took part in cognitive think-aloud interviews, while completing the same measures. Transcribed audio recordings were analysed using inductive thematic analysis.

RESULTS

Quantitative analyses suggested high internal consistency (Cronbach's alpha 0.74-0.96) and reliability (intraclass correlation coefficient values 0.88-0.97) for both questionnaires. Both scales showed floor effects on some subdomains. Skindex-16 and CompAQ showed good evidence of construct validity when compared with Acne-QoL with Spearman's correlation coefficients 0.54-0.81, and good repeatability over 24 hours.Qualitative data uncovered wide-ranging views regarding usability and acceptability. Interviewees held strong but differing views about layout, question/response wording, redundant/similar questions and guidance notes. Similarly, interviewees differed in perceptions of acceptability of the different scales, particularly on relatability of questions and emotive reactions to scales.

CONCLUSIONS

All PROMs performed well in statistical analyses. No PROM showed superior usability and acceptability in the qualitative study. Any PROM should be acceptable for further research in adult acne but researchers should consider the different domains and whether they will measure only facial or facial and trunk acne before making a selection. A new PROM or further evaluation of novel PROMs may be beneficial.
