AlOtaibi * Nuha A. AlFurayh * Bayan M. AlNooh * Nouf A. Aljomah * Sadeem M. Alqahtani ## Abstract **Objectives:** To assess the quality of life (QoL) of patients with different dermatological diseases. Multiple international studies have evaluated the QoL among patients with different dermatological diseases; however, few studies of this kind have been conducted in Saudi Arabia. **Methods:** This quantitative, observational, cross-sectional study was carried out in the dermatology outpatient clinics of King Saud University Medical City, Riyadh, Saudi Arabia, from September 2019 until February 2020. Data was collected using the validated Arabic version of the Dermatology of Life Quality Index (DLQI). **Results:** A total of 391 patients ≥18 years participated in the study. The mean age of participants was 33 years (18-75 years). Most participants in this study reported that their dermatological disease had a small or no effect on their QoL (62.5%). The majority of patients who had acne vulgaris (79.7%), vitiligo (79.3%), hair disorders (76.9%), or rosacea (71.5%) reported a small to no effects on their QoL. However, diseases that reflected the largest percentages of a large to extremely large effect on QoL were urticaria (37.1%), eczema (26.6%), and psoriasis (24%). A total of 42.9% of the participants suffered from lichen planus and 66.7% of participants suffered from cutaneous neoplasms reported a moderate effect on their QoL. **Conclusion:** Understanding the impact of different dermatological diseases on QoL can help dermatologists to improve thier patients’ QoL. Therefore, we recommend that further studies on this topic be conducted in multiple health centers. * Quality of life * dermatological diseases * dermatology * Saudi Arabia **C**onsidering that the skin is the largest and most visible organ of the body, illnesses that affect it can impair quality of life (QoL). Different aspects of an individual’s life, including daily activities, work, social life, and emotional functioning, can be affected by chronic skin problems.1 The negative impacts of dermatological diseases (such as psoriasis, eczema, acne vulgaris, vitiligo, and hair disorders) depend on many factors, including the location and activity of the disease, the body surface area involved, and associated symptoms, such as itching, pain, and discomfort.2 The impacts of dermatological diseases are often underrated due to the chronic nature of these illnesses and because few of them are life threatening. However, according to McKoy’s3 study, approximately 21-87% of the population may be affected by at least one type of skin disease. Almost one quarter (24%) of patients who visit a primary care clinic seeking treatment for a skin disease do so due to an unfavourable self-image, disfigurement, or other physical impairments.3 As mentioned by Rapp et al,4 although psoriasis and other types of skin diseases are not life threatening, they can severely impact a patient’s QoL. The psychological effects of dermatological diseases are due to the noticeable lesions, which can result in feelings of discomfort, low self-esteem, social disapproval, and social isolation.4,5 In addition, active, severe skin dermatoses can impair other aspects of an individual’s life, such as sexuality, which can impact QoL and can be the underlying cause of an individual’s inability to work, leading to work withdrawal or reduced productivity at work.4-6 All of these impacts can then lead to anxiety, depression, or social maladaptation.6 The various adverse effects of different skin problems negatively impact QoL; these effects, in turn, might affect treatment compliance and the course of the disease. Therefore, measures of QoL can help dermatologists monitor disease progression. Quality of life measures assess various aspects of a patient’s life, including physical activity and emotional, professional, and social functioning. These measures can be used to improve existing management options or to indicate the need for new ones.7 Although multiple studies have evaluated the QoL of patients with different dermatological diseases in developed countries, there are still insufficient data about the impact of skin diseases on the QoL of patients in developing countries. Moreover, few studies of this kind address multiple types of skin diseases and their impacts on QoL. The present study aimed at assessing the QoL among patients from Saudi Arabia suffering from different dermatological diseases, using the Dermatology of Life Quality Index (DLQI) tool. ## Methods A quantitative, observational, cross-sectional study was conducted at the dermatology outpatient clinics of King Khalid University Hospital, Riyadh, Saudi Arabia. The study lasted for 6 months from September 2019 until February 2020 and assessed the QoL index among patients suffering from a range of dermatological diseases. Male and female patients ≥18 years were enrolled in the study. Patients who were unable to understand the study terms or to provide written consent were excluded. After the required institutional review board approval was obtained, a self-administered questionnaire was distributed to participants. The questionnaire was divided into 3 sections. The first section collected demographic information, such as gender, age, and marital status. The second section gathered data on the participant’s dermatological disease, including diagnosis, time since diagnosis, type and duration of treatment, and any other comorbid diseases. The third section consisted of the validated Arabic version of the DLQI, and was used in this study with permission. Data was analysed using The Statistical Package for the Social Sciences, Version 21.0 (IBM Corp., Armonk, NY, USA). ## Results A total of 391 patients participated in the study. One returned questionnaire was excluded due to incomplete data. More women than men responded to the questionnaire; 91% of participants were female, and 8.7% were male. The mean age of participants was 33 years, and their ages ranged from 18-75 years. Most of the respondents were single (59.7%), and 33% of the participants had been suffering with a skin disease for more than 5 years. Nineteen percent of participants were diagnosed 2-5 years before the start of the study, 14.6% were diagnosed 1-2 years before the study, and 28% were diagnosed less than one year before the study began. Each participant was assigned to one of the following diagnostic categories presented in Table 1. The total DLQI score could range from 0-30; the total score reflects the magnitude of the effect of the disease on QoL. Impact is categorized as no effect or a small, moderate, large, or extremely large effect. Most participants reported that their illness had a small to no effect on their QoL. More than two-thirds of the population with acne vulgaris reported a small to no effect, whereas the remaining acne patients reported variable scores ranging from moderate to extremely large. Similarly, large percentages of patients with vitiligo, hair disorders, and rosacea reported a small to no effect on QoL. In contrast, around 37% of the participants with urticaria, 26.6% of those with eczema, and 24% of those with psoriasis reported a large to an extremely large effect on QoL, and 22.2% of those with urticaria, 24.4% of those with eczema, and 28% of those with psoriasis reported a moderate effect on QoL. The largest cohorts of participants with lichen planus and skin neoplasms reported a moderate effect on QoL (Table 1). View this table: [Table 1](http://smj.org.sa/content/42/11/1195/T1) Table 1 - The impact of certain dermatological diseases on patients’ QoL. Table 2 illustrates the possible risk factors that contributed to the impact of dermatological disease on QoL. The percentage of participants who reported an extremely large effect on QoL increased as disease duration and treatment period increased. Approximately 68% of participants with localized cutaneous disease reported a small to no effect on QoL compared to 46% of participants with generalized skin diseases. Most participants reported that they did not have any other, non-dermatological diseases (~60%), and 73% reported that they did not use other medications. View this table: [Table 2](http://smj.org.sa/content/42/11/1195/T2) Table 2 - The contribution of disease characteristics and treatment characteristics on patients’ quality of life (QoL). Further analysis of the elements addressed in the DLQI showed that most of participants responded to most elements with “a little” to “a lot”. However, they were less likely to respond with “very much”. Itchiness/pain (10.5%), impressment (9.7%), and difficulties due to clothes wearing (9.2%) have stronger negative impacts than other elements for which participants said that these issues impact their QoL “very much” (Table 3). View this table: [Table 3](http://smj.org.sa/content/42/11/1195/T3) Table 3 - Analysis of dermatology life quality index (DLQI) elements in patients with different dermatological diseases (N=390). Participants with different skin diseases responded to each element of the DLQI differently, and responses ranged from “a little” to “very much”. Itchiness/pain had statistically significant associations with urticaria, eczema, seborrheic dermatitis, psoriasis, and acne. Urticaria, eczema, and acne had statistically significant impacts on home duties and shopping. Embarrassment and effect on social/leisure activities had statistically significant associations with several skin disorders, including hyperpigmentation, hair disorders, and urticaria. Impairments related to wearing clothes were more common among participants with acne, urticaria, hair disorders, and cutaneous neoplasms. Participants with skin infections, neoplasms, and urticaria were more likely to report difficulties with physical activity. Impacts on working/studying were not significant except among participants with hair disorders and urticaria. Although participants reported a range of impacts on sexual activity and relationships with partners, friends, and relatives, only urticaria had a statistically significant association with these elements. Acne, hyperpigmentation disorders, neoplasms, and urticaria showed significant associations with treatment problems. Urticaria was the only dermatological disease in our study that significantly affected all elements of QoL addressed by the DLQI (Table 3). ## Discussion Dermatological diseases vary in many ways, including symptoms, chronicity, and cosmetic effects. These findings mean that these diseases have a range of impacts on patients’ QoL. Several previous studies assessing the impact of dermatological diseases on QoL have reported significant impairment.6,8-12 However, a single national study published 8 years ago observed better impact on QoL.7 Nevertheless, despite constant developments in the treatment of these diseases, including the use of biological therapies to treat many dermatological diseases, a lack of recent data on the QoL of patients with dermatological diseases in Saudi Arabia exists. Different tools have been developed to assess the QoL of patients with skin diseases. We found that the validated Arabic version of DLQI questionnaire was understandable and easy for participants to use. In addition, as previous studies have concluded, scoring the DLQI is simple and fast.13 This questionnaire is not only used by dermatologists; primary care physicians frequently employ it as well.14 The current study demonstrated that the QoL of adults with different skin diseases is impaired to varying degrees. Most of our participants (62.6%) reported that their illness had a small to no impact on their QoL; this finding is similar to a previous study.7 The dermatological diseases that most impact QoL in the present study are urticaria, psoriasis, and eczema. This finding aligns with previous studies conducted in Saudi Arabia and in other countries.6,8,9,11,15 Other authors have found that acne and vitiligo have the strongest negative impacts on QoL.16,17 In our analysis of sociodemographic characteristics, no significant difference was found in relation to gender. However, most participants in this study were female (91%). This percentage is similar to that in previously published studies in which most participants were also females.6-8 In this study, the prevalence of female patients, could be explained by the fact that women visit dermatology clinics more often than men. Different dermatological diseases have different impacts on each element in the DLQI. In the present study, urticaria was the only disease that had a significant negative impact on all domains of the DLQI. This finding aligns with a 2018 study.15 The most common impact overall was itchiness/pain followed by embarrassment and discomfort related to clothing. The authors propose that these symptoms are usually the most bothersome for patients with dermatological diseases. We also examined factors influencing the impact of dermatological diseases on different elements of the DLQI and found that the negative impact increases with prolonged disease duration, more body involvement, and the presence of other chronic diseases; married participants also reported stronger negative impacts than unmarried ones. A previous study found that impaired QoL was associated with a younger age, a lower income, being unmarried, having only one skin condition, and a longer disease duration.18 The finding that longer duration impacts QoL more severely aligns with our findings. The DLQI allows patients with dermatological diseases to express their feelings in a structured way, and their responses can help physicians be more aware of their patients’ problems. Many studies have investigated the impact of skin diseases on QoL, but few have evaluated the precise elements related to QoL that are impacted by each individual disease. ### Study limitations This study was conducted at a single tertiary health care center, which limits the feasibility of generalizing the findings to all individuals with skin diseases. Though it is relatively difficult to conduct population-based studies of dermatological diseases, we encourage more centers to reflect on the burden of the skin diseases using this easy, validated tool. In addition, the varied number of participants in each diagnostic category in the current study may have caused some discrepancies in the findings. Hence, further studies with larger sample sizes are recommended. In conclusion, understanding the impact of different dermatological diseases on patients’ QoL can help dermatologists to improve their patients’ QoL. This study has shown that dermatological diseases have variable impact on patients’ QoL. We recommend conducting further studies on this matter in multiple health centers with larger number of patients and different quality measurement tools. ## Acknowledgment *The authors gratefully acknowledge American Manuscript Editors ([www.americanmanuscripteditors.com](http://www.americanmanuscripteditors.com)) for English language editing.* ## Footnotes * **Disclosure.** Authors have no conflict of interests, and the work was not supported or funded by any drug company. * Received August 3, 2021. * Accepted September 28, 2021. * Copyright: © Saudi Medical Journal This is an Open Access journal and articles published are distributed under the terms of the Creative Commons Attribution-NonCommercial License (CC BY-NC).
