Epidemiology of dermatologic disease in Palau: a cross-sectional study in the national public and community health service

Background Dermatologic disease is a neglected public health challenge that disproportionately affects resource-poor settings. Globally, the dermatologic disease contributes the fourth highest burden of nonfatal disability with the most acute impact in the Oceanic region, including the Republic of Palau. Efforts to address the dermatologic health inequality are hindered without the necessary epidemiologic evidence to guide health policy in the resource-poor setting of Palau. Methods We conducted a 4-year cross-sectional study of all Dermatology Service patients in the Belau National Hospital and outreach community health centers from 2015 to 2018. No other specialized dermatology service was available. Skin disease was both classified by diagnosis and Global Burden of Disease criteria and analyzed by age, gender, region, and surrounding Oceanic nations. Results The study enrolled 494 patients comprising 179 males and 315 females between 2015 and 2018. The most prevalent diseases were eczema (48.8%), superficial fungal infection (24.5%), and pruritus (22.7%). The neglected tropical disease of scabies was detected in four patients. Males were significantly more likely to present with cellulitis, keratinocyte carcinoma, stasis dermatitis, wounds, marine-related dermatitis, viral skin disease, tinea faciei, verruca, and xerosis and females with melasma and hyperpigmentation. Conclusion This study presents the first primary epidemiologic data describing the prevalence of dermatologic disease in the Palauan adult population. The significant burden of disease in Palau compared with other Oceanic nations validates ongoing dermatology services and informs public health implications for resource allocation and disease management to achieve health equality in the resource-poor nation.

Automated summary

This study provides preliminary epidemiologic data on the prevalence of dermatologic disease in the adult population of Palau. It highlights the heavy burden of dermatologic disease in Palau compared to other Oceanic nations, emphasizing the need for ongoing dermatology services to achieve health equality.
