The Global Prevalence of Seborrheic Dermatitis: A Systematic Review and Meta-Analysis

Importance

Seborrheic dermatitis is a prevalent chronic inflammatory skin disease, yet its global prevalence, pathogenesis, and epidemiology remain inadequately defined.

Objective

To provide a detailed estimation of the global prevalence of seborrheic dermatitis, analyze demographic variations, and explore differences in various settings.

Data Sources

Embase, PubMed, Scopus, and Cochrane Database of Systematic Reviews were searched from inception through October 2023.

Study Selection

Original investigations on seborrheic dermatitis prevalence were included after duplicate screening of titles, abstracts, and full articles, including only studies with clinician-diagnosed cases.

Data Extraction and Synthesis

Following PRISMA guidelines, data were extracted and quality was assessed independently by multiple reviewers. A random-effects model using restricted maximum likelihood was used for meta-analysis and subgroup analyses.

Main Outcome and Measure

The primary outcome was the pooled estimate of global seborrheic dermatitis prevalence.

Results

From 1574 identified articles, 121 studies were included, encompassing 1 260 163 individuals and revealing a pooled global seborrheic dermatitis prevalence of 4.38% (95% CI, 3.58%-5.17%), with significant heterogeneity (I2 = 99.94%). Subgroup analyses showed variations by age, with a higher prevalence in adults (5.64% [95% CI, 4.01%-7.27%]) compared to children (3.70% [95% CI, 2.69%-4.80%]) and neonates (0.23% [95% CI, 0.04%-0.43%]). Geographic analyses indicated variability, with the highest prevalence in South Africa (8.82% [95% CI, 3.00%-14.64%]) and the lowest in India (2.62% [95% CI, 1.33%-3.92%]).

Conclusions and Relevance

This comprehensive meta-analysis provides a detailed estimation of the global prevalence of seborrheic dermatitis, highlighting significant variability across different demographics and settings.

Secure Messaging: Demonstration and Enrollment Patient Portal Program: Patient Portal Use in Vulnerable Populations

Vulnerable populations face challenges gaining access to quality healthcare, which places them at a high risk for poor health outcomes. Using patient portals and secure messaging can improve patient activation, access to care, patient follow-up adherence, and health outcomes. Developing and testing quality improvement strategies to help reduce disparities is vital to ensure patient portals benefit all, especially vulnerable populations. This quality improvement initiative aimed to increase enrollment in a patient portal, use secure messages, and adhere to follow-up appointments. Before the project, no patients were enrolled in the portal at this practice site. Over 8 weeks, 61% of invited patients were enrolled in the patient portal. Eighty-five percent were Medicaid recipients, and the others were underinsured. Eight patients utilized the portal for secure messaging. The follow-up appointment attendance rate was better in the enrolled patients than in those who did not enroll. The majority of survey respondents reported satisfaction in using the patient portal. Patient portal utilization and adoption in vulnerable groups can improve when a one-on-one, hands-on demonstration and technical assistance are provided.
