The population-based UPLIFT survey was conducted to understand how perceptions of treatment-related outcomes have evolved, particularly for patients with mild to moderate PsO and/or PsA and their dermatologists. METHODS: This population- and web-based survey was conducted from 2 March to 3 June 2020, in North America, Europe, and Japan. Adults with self-reported healthcare practitioner (HCP)-diagnosed PsO and/or PsA and dermatologists who spent > 50% of time treating patients and treated ≥ 20 patients with PsO, including plaque PsO, per month were included. Patient participants were recruited at random from online panels; dermatologists were recruited randomly from representative physician panels. RESULTS: Of 264,054 patient responses, 3806 who self-reported an HCP diagnosis of PsO and/or PsA were included in the final sample; 67% had PsO alone, 28% had PsO and PsA, and 5% had PsA alone. The estimated population prevalence of psoriatic disease was 7% (PsO only: 4%; PsO and PsA: 2%; PsA only: 1%). Most patients (78%) reported PsO-involved body surface area (BSA) ≤ 3 palms, and ~ 90% or more reported itching, redness, flaking, and scales. Many PsO patients without diagnosed PsA reported musculoskeletal symptoms suggestive of PsA (63%). Across BSA categories, approximately one in four patients was not currently receiving treatment and > 50% had Dermatology Life Quality Index score > 5. Patients and dermatologists had different perceptions of PsO severity, office visit discussions, treatment goals, and treatment satisfaction. The survey was conducted during the coronavirus disease 2019 (COVID-19) pandemic, which could have affected assessments of patient-reported outcomes and ability to have in-person HCP visits. CONCLUSIONS: Patients with PsO and PsA in UPLIFT reported high disease burden, including patients with limited skin involvement. An opportunity exists to align patient and dermatologist perceptions to optimize management of PsO and PsA.

Many PsO patients without diagnosed PsA reported musculoskeletal symptoms suggestive of PsA (63%). Across BSA categories, approximately one in four patients was not currently receiving treatment and [ 50% had Dermatology Life Quality Index score [ 5. Patients and dermatologists had different perceptions of PsO severity, office visit discussions, treatment goals, and treatment satisfaction. The survey was conducted during the coronavirus disease 2019 (COVID- 19) pandemic, which could have affected assessments of patient-reported outcomes and ability to have in-person HCP visits. Conclusions: Patients with PsO and PsA in UPLIFT reported high disease burden, including patients with limited skin involvement. An opportunity exists to align patient and dermatologist perceptions to optimize management of PsO and PsA. In recent years, several new treatments for psoriasis and psoriatic arthritis have become available. The UPLIFT survey was conducted to understand how viewpoints on psoriatic disease outcomes have changed, especially for patients whose disease is mild or moderate. UPLIFT was a large, online, population-based survey conducted in North America, Europe, and Japan. Adults with psoriasis and/or psoriatic arthritis and dermatologists who treated at least 20 patients with psoriasis per month were included. There were 3806 patients who participated; of these, most had psoriasis and few had psoriatic arthritis. Most patients (78%) with mild to moderate psoriasis had a limited area of skin affected by psoriasis. Psoriasis symptoms were common and included itching, redness, flaking, and scales. Many patients without a diagnosis of psoriatic arthritis reported symptoms that could be related to this disease (such as joint discomfort). Although many patients had psoriasis symptoms, approximately one in four was not currently receiving treatment and more than half reported psoriasis impacted their quality of life. Patients and dermatologists had different perceptions of psoriasis severity, office visit discussions, treatment goals, and treatment satisfaction. There is an opportunity to improve treatment of psoriasis and psoriatic arthritis and to better align patient and physician perceptions of psoriasis. This survey was conducted during the COVID-19 pandemic, which could have partially affected some assessments and the ability to have in-person doctor visits. Keywords: Health survey; Patient satisfaction; Psoriasis; Psoriatic arthritis; Quality of life; Special area; Symptom; Treatment The impact of new systemic treatments for psoriasis and psoriatic arthritis on perceptions of psoriasis and its treatment is not fully understood. The Understanding Psoriatic Disease Leveraging Insights for Treatment (UPLIFT) survey aimed to understand how patient perceptions of treatment-related outcomes have evolved since the 2012 Multinational Assessment of Psoriasis and Psoriatic Arthritis (MAPP) survey, particularly for patients with mild to moderate psoriasis and/or psoriatic arthritis. The UPLIFT survey found persistent unmet needs and differences in perceptions of disease severity and treatment satisfaction between patients and physicians. There are opportunities to include special area involvement in assessments of disease severity, to enhance relationships between patients and dermatologists, and to improve outcomes in patients with psoriasis across the disease severity continuum. In 2012, the Multinational Assessment of Psoriasis and Psoriatic Arthritis (MAPP) survey was conducted to characterize the burden of psoriasis (PsO) and psoriatic arthritis (PsA), as well as patient and physician perceptions, and to identify unmet treatment needs [1, 2] . The MAPP survey provided valuable patient-reported findings demonstrating a profound impact of psoriatic disease on quality of life (QOL), high symptom burden, and undertreatment in patients with PsO and/or PsA [1, 2] . Since the MAPP survey was conducted [1] , new systemic treatments have been approved with an efficacy permitting clear skin and nearly clear skin in the majority of patients [3] [4] [5] [6] , and patient perceptions of treatment-related outcomes may have changed [7, 8] . These treatments represent different mechanisms of action and provide physicians and patients with options to effectively manage psoriatic disease to the extent that treatment targets in guidelines have been upgraded to clear and nearly clear skin [7] [8] [9] [10] . Furthermore, the perception that PsO should be regarded as a systemic disease has expanded under dermatologists [11] . To better understand how patient perceptions of treatment-related outcomes have evolved since the 2012 MAPP survey, particularly for patients with mild to moderate PsO and/or PsA, the Understanding Psoriatic Disease Leveraging Insights for Treatment (UPLIFT) survey was designed based on insights from MAPP and administered to patients and physicians. Despite the efficacy of available treatments, research suggests that a high burden of disease persists, particularly among patients with bothersome PsO symptoms such as itch, involvement in special areas, or musculoskeletal symptoms [1, 2, 12] . These disease manifestations can result in substantial QOL impairment even in patients who have limited skin involvement [1, 12] . The MAPP survey also highlighted the disconnect between patient and dermatologist perceptions of psoriatic disease severity, indicating that traditional measures of disease severity used by physicians do not fully capture the impact of PsO on patients' lives and mental health [1, 2, 13, 14] . These different perceptions may explain why some patients with PsO who may benefit from systemic treatment remain on topical therapies [1] . However, topical therapies can be ineffective, inconvenient, or difficult to apply, particularly for patients with PsO in special areas, and do not address the systemic nature of the disease in many patients [15] . Also, joint involvement is often unrecognized in patients with PsO, and patients with mild to moderate PsA may require systemic treatment [1, 16] . When defining disease severity and selecting treatment, current guidelines and international expert consensus recommend considering symptoms and involvement of areas associated with high disease burden, response to topical treatment, and impact of psoriatic disease on QOL in addition to objective measures of disease severity [7, 9, 17, 18] . Because current treatment goals may be more ambitious than they were when MAPP was conducted, it is important to evaluate how the treatment landscape has changed for patients with psoriatic disease. Data from UPLIFT provide an updated account of the status of the psoriasis field for patients and dermatologists. We present key patient-reported data from UPLIFT, with particular focus on PsO disease burden and current treatments. We also describe patient and dermatologist perceptions of factors contributing to disease severity and treatment expectations. The methodology and design of the UPLIFT survey were developed with input from a steering committee consisting of international experts in dermatology and rheumatology. The survey was conducted by AplusA Bell Falla between 2 March 2020 and 3 June 2020. AplusA is a member of major national professional organizations (notably Intellus, ESOMAR, and EphMRA) and adheres to the international code of marketing and social research practice. The protocol was submitted for approval to a central institutional review board (Advarra) in the USA to comply with human subject research requirements. The central institutional review board approval included oversight of all survey activities, as well as the conduct of the survey within Canada, France, Germany, Italy, Japan, Spain, the UK, and the USA. The survey was conducted in accordance with the ethical principles that have their origin in the Declaration of Helsinki. Survey conduct was consistent with good clinical practices and applicable laws and regulations. Informed consent was obtained prior to survey procedures. UPLIFT was a cross-sectional, quantitative web-based survey conducted in Canada, France, Germany, Italy, Japan, Spain, the UK, and the USA and administered in the respective local language(s). Completing the survey required * 25 min for the patient survey and * 30 min for the physician survey. Pretests were conducted before the survey to assess the clarity, understanding, and interpretation of questions and to determine the ease of use and participant experience, including interview length. Patients were recruited at random from the general population of an online panel of adults, and the sample was balanced for representative populations by region. Panel sources included loyalty panels (e.g., travel, entertainment, media, and retail recruitment programs); organic, open enrollment, and partnership recruitment (including websites, social media influencers, and mobile apps); and affiliate network recruitment (including school and community websites). Patient recruitment was stratified to general population demographics based on sex, age, and region for the respective countries. In the USA, participants who were panelists in the National Psoriasis Foundation were not randomly selected and were excluded from analyses of the prevalence of PsO and PsA diagnoses. For the physician survey, dermatologists were recruited using random selection methods in all countries and sourced from representative panels of physicians. Dermatologists were qualified based on a screening questionnaire. The target sample was 3800 patients and 450 dermatologists, with individual quotas for each country. The number of survey participants was selected as a convenience sample based on participant accessibility by the patient and healthcare provider (HCP) panels. No particular variable was considered to be the most important for the descriptive summary in the primary objective. Subsequently, the anticipated enrollment rate was a factor in determining the final sample size. Adults (age C 18 years) with a self-reported HCP diagnosis of PsO and/or PsA were eligible to participate in the patient survey. The physician survey included dermatologists who reported they spend C 50% of their professional time directly treating patients and C 50% of office visits specifically on medical dermatology, and who see C 20 patients with PsO in a typical month, including adults with plaque PsO. Custom and validated patient assessments were conducted, including respondent demographics and clinical characteristics, presence of PsO in all areas and in areas of high disease burden (i.e., genital, nail, scalp, palms, and soles), musculoskeletal/PsA symptoms, Psoriasis Epidemiology Screening Tool (PEST) scores, selfreported skin involvement by PsO-involved BSA (assessed by number of palms based on the palm of the hand including fingers), self-rated current disease severity [1-3 (mild), 4-6 (moderate), 7-10 (severe)], Health Assessment Questionnaire-Disability Index (HAQ-DI) item 8 (HAQ-8), Dermatology Life Quality Index (DLQI), Patient Health Questionnaire-2 (PHQ-2), patient satisfaction with PsO treatment options, and current treatment. Physician responses included dermatologists' satisfaction with PsO treatment options and their perceptions of patient satisfaction with PsO treatment options. Patient and dermatologist alignment on determinants of disease severity, treatment priorities, and treatment goals was assessed; respondents were asked to rank their top three contributing factors for each metric. Survey results for the patient and dermatologist survey responses were summarized descriptively. Data for patient-rated current disease severity, current treatment, and DLQI were analyzed by level of BSA skin involvement (B 3 palms, 4-10 palms, or [ 10 palms). An analysis of patients with limited skin involvement (BSA B 3 palms) and PsO in at least one special area (i.e., scalp, nails, palms and/or soles, face, and genitals) evaluated patient-rated current disease severity, current treatment, and DLQI score. Data were summarized using descriptive statistics without data imputation using SAS Enterprise Guide 7.15 HF9 software (SAS, Cary, NC). Of 264,054 responses (i.e., participants who clicked on the survey link), 227,637 answered the diagnostic screening question (i.e., ''Have you ever been diagnosed by a doctor, or other healthcare practitioner, to have any of these conditions?'') for PsO and PsA; 3806 patient respondents who self-reported an HCP diagnosis of PsO and/or PsA and met inclusion criteria were included in the final sample. Reasons for exclusion included incomplete screening questionnaire, not meeting the survey criteria, incomplete interview response, and responses received after the survey was closed. The number of patients who completed the survey in each country is provided in Table 1 . Most patients responding to the survey had PsO without PsA (67%), 28% had PsO and PsA, and 5% had PsA without PsO. Overall, the population prevalence of psoriatic disease was estimated to be 7%, including 4% of patients with PsO only, 2% with PsO and PsA, and 1% with PsA only ( Table 1 ). The estimated population prevalence of PsO and/or PsA was highest in Italy (11%) and lowest in Japan (2%) ( Table 1) . Mean patient age was 45.1 years, and approximately half of patients were men ( Table 2 ). The most reported comorbidities were hypertension, depression, and arthritis (patient-reported, HCP-diagnosed osteoarthritis or rheumatoid arthritis; Table 2 ). Among the 473 dermatologists who completed the survey, 51% practiced in a hospitalbased setting and 49% practiced in a community-or office-based setting. Dermatologists reported that they spent most of their time (91%) treating patients. They treated an average of 501 patients per month in their practices (mean with PsO: n = 71; mean with PsO and PsA: n = 31), and 78% of their patients with PsO had plaque PsO. The majority of patients with PsO and/or PsA currently experiencing PsO symptoms reported BSA B 3 palms (78%, n = 3200; Fig. 1 ). Among patients with BSA B 3 palms, 58% rated their current PsO symptoms as moderate or severe (Fig. 1) . Patients commonly reported PsO involvement in special areas, and more than half of patients had scalp involvement ( Table 2) . Most patients reported PsO symptoms; itching, redness, flaking, and scales occurred in * 90% of patients or more (Table 2) . Among patients with PsO alone (n = 2550), 58% reported experiencing joint discomfort; of these (n = 1485), 63% had B 4 involved joints (consistent with oligoarthritis). When asked if they have experienced PsA symptoms, many patients with PsO alone reported morning stiffness of the joints (44%), nail involvement (32%), pain and/or swelling of the feet (24%), or ''sausage'' digits (18%); 33% responded none of the above, and 4% responded not sure. Overall, 42% of patients with PsO alone who had joint discomfort had PEST score C 3, suggesting that referral to a rheumatologist should be considered [19] . Among patients with PsO who experienced joint discomfort (overall: n = 1485; B 4 joints: n = 942; [ 4 joints: n = 543), 33% of Among patients with PsO or PsO and PsA currently experiencing PsO symptoms (n = 3200), C 50% of patients with BSA [ 3 palms were receiving systemic therapy (i.e., oral and/or biologic therapy) compared with 35% of those with B 3 palms; however, substantial proportions of patients were not receiving any treatment or only topical therapy. Across BSA categories, 12% ([ 10 palms) to 29% (B 3 palms) of patients reported they were not currently receiving any treatment for their PsO (Fig. 2) . Across BSA categories, approximately 29% of patients reported using topical prescription therapy only, approximately 20% oral therapy (oral prescription only or oral prescription ? topical prescription therapy), 10% biologic therapy (biologic only or biologic ? topical prescription therapy), and 11% both oral and biologic therapy (oral prescription ? biologic, or topical prescription ? oral prescription ? biologic) (Fig. 2) . Overall, in patients with PsO and/or PsA (n = 3614), mean DLQI score was 9.3, and 56% of patients experienced at least a moderate impact on QOL (DLQI score [ 5) . In patients with PsO involvement in at least one special area (n = 2776), the mean (SD) DLQI total score was 9.9 (8.5) and 57.9% reported DLQI total score [ 5. The proportion of patients with at least a moderate effect of PsO on QOL was greater among patients with involvement in at least one special area versus no special area involvement; the proportion of patients with DLQI total score [ 5 was highest for patients with face involvement and lowest for patients with scalp involvement (Fig. 3) . For each item in the DLQI questionnaire, mean DLQI scores were higher for patients with PsO involvement in at least one special area compared with patients with no special area involvement (Fig. 4) . Also, mean DLQI scores for individual questions were generally lowest in patients with scalp PsO and higher for patients with involvement in other special areas, such as the face (Supplementary Fig. 1 Approximately half of patients (52%) with PsO and/or PsA (n = 3806) screened positive for potential major depressive disorder, according to PHQ-2 guidelines (i.e., PHQ-2 score C 3). Patients with DLQI total score [ 5 and PsO in at least one special area who also had PHQ-2 score C 3 had higher mean (SD) DLQI total scores [16.8 (6.7); n = 1203] compared with all patients with DLQI total score [ 5 and PsO in at least one special area [15.5 (6.85) ; n = 1607, without positive depression screen]. In UPLIFT, 60% of PsO patients with limited BSA and involvement (BSA B 3 palms) in at least one special area (n = 1927) reported their current disease as moderate or severe. Of these, 51% were receiving topical treatment or no treatment. In this group of patients, mean DLQI score was 9.4, and more than half of patients (56.4%) had a DLQI score [ 5. Patients ranked the types of symptoms, duration of PsO, and location of skin lesions as the most important factors defining disease severity ( Supplementary Fig. 2 ). By contrast, dermatologists ranked impact on overall QOL, amount of BSA involvement, and type of symptoms as the top three factors contributing to disease severity ( Supplementary Fig. 2) ; disease duration was ranked tenth, and location of lesions was ranked fourth, for dermatologists. When recalling office visits, considerably more patients than dermatologists reported never discussing joint pain, related conditions, and the impact of PsO on emotional well-being ( Supplementary Fig. 3 ). For patients, itch reduction was the most important treatment goal, followed by symptom control and skin clearance ( Supplementary Fig. 4 Mean DLQI question scores in patients with and without special area involvement. Error bars represent standard deviation. DLQI Dermatology Life Quality Index, PsO psoriasis Fig. 2) , whereas dermatologists rated itch reduction as a less important treatment goal and ranked improving QOL as the most important goal (Supplementary Fig. 2 ). Despite these differences, most patients and dermatologists ([ 80%) believed their treatment goals were very closely or somewhat closely aligned. When looking at practice characteristics (e.g., work setting, number of patients per month, percentage of patients with PsO, and disease severity of PsO patients) of dermatologists ranking similar drivers of severity and treatment goals as patients, little difference was observed compared with those dermatologists not ranking factors prioritized by patients. Patients and dermatologists both considered skin clearance and long-term efficacy to be the most important attributes of an ideal PsO therapy ( Supplementary Fig. 2 ). In addition, dermatologists considered long-term safety to be a top attribute (Supplementary Fig. 2 ). Approximately 70% of patients with PsO and/or PsA who had current or prior topical treatment (n = 3129) reported being satisfied with the effectiveness (67%), convenience (71%), and safety (73%) of prescription topical medications for PsO; however, the majority considered topical medications to be burdensome (75%). The most common reasons for the perceived burden of topical treatments included mess (54%), frequency (38%), and duration of application (32%) (Supplementary Fig. 4 ). Many patients with PsO and/or PsA who had current or prior oral treatment (n = 2111) reported being satisfied with the effectiveness (66%), convenience (71%), and safety (61%) of prescription oral medications; however, many (66%) considered oral treatments to be burdensome. Top reasons why patients considered oral treatments to be burdensome included side effects (33%), frequency of dosing (32%), and required monitoring of blood levels (29%) (Supplementary Fig. 4 ). More than half of patients (57%) (n = 1208) had discontinued oral treatment. The most common reasons for discontinuing oral treatments included lack of effectiveness (28%), loss of treatment effectiveness over time (22%), adverse effects on other organs (19%), and lack of tolerability (18%) (Supplementary Fig. 5 ). In patients with PsO and/or PsA and current or prior injectable or intravenous treatment (n = 1426), 65% were satisfied with their effectiveness, 60% were satisfied with their convenience, and 58% were satisfied with their safety; however, most patients (84%) reported that these treatments were burdensome. The most common reasons for the perceived burden of injectable or intravenous treatments included fear of adverse events (24%), mental anxiety about preparing for self-injection (24%), and fear of developing immunity or resistance (23%) (Supplementary Fig. 4) . A total of 57% of patients (n = 817) had discontinued treatment with an injectable or intravenous medication. The most common reasons for discontinuing injectable or intravenous medications included symptom improvement (19%), concerns regarding long-term safety issues (18%), and needle fatigue (18%) (Supplementary Fig. 5) . The majority of dermatologists (n = 473) reported being somewhat or very satisfied with the short-term (C 88%) and long-term effectiveness (C 74%), convenience (C 79%), tolerability (C 88%), and long-term safety (C 79%) of current treatment options for PsO. Furthermore, dermatologists (n = 473) perceived that more than half of patients with mild (62%), moderate (59%), and severe (57%) PsO were satisfied with current treatment options. Overall, 84% of patients (n = 3614) and C 73% of dermatologists (n = 473) reported they believe there is a moderate or strong need for better therapies for PsO, particularly for patients with moderate PsO. Among patients who reported that topical therapies were ''moderately'' or ''very'' burdensome, there was an increased prevalence of PsO involvement in at least one special area, particularly scalp and face involvement, compared with those who reported that topical therapies were ''not at all'' or ''only a little'' burdensome ( The large, multinational UPLIFT survey provided important insights into patient and physician perceptions regarding disease burden and treatment of psoriatic disease. Although new treatments have changed the treatment landscape for PsO and/or PsA since the MAPP survey was conducted in 2012, UPLIFT identified a persistent unmet need for better management of psoriatic disease and several areas in which patient and dermatologist perceptions are not aligned. Similar to the MAPP survey, two-thirds of patients in UPLIFT had PsO without PsA [1] . However, the estimated population prevalence of PsO and/or PsA in UPLIFT (7%) was higher than that reported in the 2012 MAPP survey (1.9%) [1] and in a recent global metaanalysis (1.1%) [20] . Also, many comorbidities were more prevalent among patients in UPLIFT compared with MAPP, despite patients being younger on average in the UPLIFT versus the MAPP survey [1] . The reasons for these differences in comorbidities are not fully understood but may reflect regional variations or differences in survey methodology. For example, patients recruited for online surveys may be generally younger, more educated, and more likely to have private health insurance than patients recruited for phone surveys such as MAPP [21] ; therefore, the UPLIFT population may have been more aware of health conditions and may have been more likely to respond in the affirmative to screening questions for other health conditions. It is also possible that patient awareness of comorbidities and health literacy have increased in the years since the MAPP study was conducted and contributed to differences in comorbidity rates between MAPP and UPLIFT. Despite these differences, common comorbidities in UPLIFT, such as cardiovascular diseases and depression, were similar to comorbidities commonly reported in the Global Burden of Disease Study, a large multinational study that analyzed PsO trends from 1990 to 2017 [22] . Patients in the UPLIFT survey reported relatively high disease burden and unmet need, particularly for a population in which more than three-quarters had limited skin involvement (B 3 palms). For example, many patients had PsO involvement in special areas, reported bothersome symptoms such as itching and pain, and perceived their current PsO symptoms as moderate or severe. Moreover, many PsO patients without a PsA diagnosis were exhibiting joint symptoms or had PEST scores warranting referral to a rheumatologist, yet few patients were treated with systemic therapy. Patients in UPLIFT also had mean DLQI scores that indicated at least moderate impairment in QOL, including patients with limited skin involvement. The impact of PsO on QOL was greater among patients with involvement in at least one special area versus those without special area involvement and in patients with a positive depression screen. Considering that greater PsO severity has been associated with increased risk of anxiety or depression, screening for depression using validated assessments may be warranted in patients who demonstrate a high impact of PsO on their QOL [14] with subsequent referral to a mental health professional. In UPLIFT, patients with PsO involvement in any special area had increased QOL burden, which is consistent with prior research showing a relationship between PsO in visible and sensitive special areas and QOL impairment [23] . These findings further support recommendations from current treatment guidelines, which acknowledge the importance of PsO location and QOL when evaluating disease severity in patients with limited skin involvement [7, 9, 24] . Despite the high disease burden and increased number of available treatments, substantial proportions of patients in UPLIFT reported they were not receiving any treatment for their PsO and/or PsA. Although the proportion of patients with PsO in special areas was numerically higher in UPLIFT versus MAPP, the proportion of these patients who were currently receiving treatment was similar in UPLIFT compared with MAPP and compared with the National Psoriasis Foundation Surveys conducted in the USA using data from 2003 to 2011 [25] . Furthermore, in patients who had limited skin involvement and PsO in at least one special area in UPLIFT, more than half rated their disease as moderate or severe and were receiving only topical treatment or no treatment. Findings from UPLIFT highlight an opportunity to initiate systemic treatment earlier in patients who perceive their current disease as moderate or severe regardless of the level of skin involvement, particularly patients with PsO in special areas. The UPLIFT survey revealed differences between patient and dermatologist perceptions about psoriatic disease burden and treatment options. While patient responses emphasized the impact of specific symptoms of PsO, dermatologists placed greater importance on overall QOL when evaluating disease severity. Furthermore, recall of past office visit discussions differed between patients and dermatologists, highlighting an opportunity to better align patient and physician perceptions of PsO treatment and goals of therapy. These findings are in line with results from the global Harris poll, a web-based survey of patients with PsA, which found that most patients wished for increased communication with their physicians about their disease and treatment goals [26] . Considering that National Psoriasis Foundation (NPF)-American Academy of Dermatology (AAD) guidelines emphasize the importance of the patient-provider relationship in the care of patients with psoriasis [7] , results from UPLIFT suggest there is an opportunity to improve communication and patient care. Many patients also reported a high burden associated with PsO treatments, including lack or loss of effectiveness, tolerability issues, and route-of-administration concerns. Furthermore, some patients had discontinued oral or injectable/intravenous treatments because of lack of access or insurance issues. Reasons for discontinuing PsO medications among patients in UPLIFT were consistent with those reported in the Harris poll among patients with PsA [26] . Also, more than 80% of patients with PsO in UPLIFT believed there was a need for better therapies, which was generally consistent with findings from the Harris poll [26] . Taken together, findings from UPLIFT suggest there is an opportunity to further optimize treatment for many patients with PsO. For patients reporting that topical therapies were ''moderate'' or ''very'' burdensome, results from UPLIFT demonstrated an increased prevalence of special area manifestations, particularly for scalp and face involvement, compared with patients who reported that topical therapies were ''not at all'' or ''only a little'' burdensome. This finding suggests there are limitations associated with topical therapies for the treatment of PsO involvement in special areas. In addition, a greater proportion of patients reporting at least a moderate burden with topical therapies displayed symptoms of depression, had polyarthritis, and reported at least a moderate effect of PsO on their QOL compared with patients whose burden associated with topical treatments was lower. Thus, the perceived burden of topical therapies reflects a broader disease burden and highlights the importance of optimizing treatment for patients with PsO. For better access to care for these patients, it is important to recategorize disease severity assessment, including special area involvement. This survey study had some limitations inherent to survey studies, such as recall bias. Participants were selected from an online panel of adults that may not be fully representative of the general population. The survey did not include nurse practitioners or physician assistants, who often provide care to patients with psoriasis in clinical practice. Also, part of this survey was conducted during the COVID-19 pandemic. The emotional burden associated with COVID-19 may have had an impact on psychological and physiological aspects of living with psoriatic disease and could have affected assessments of patient-reported outcomes. Pandemic restrictions may have limited in-office visits and necessitated reliance on virtual visits, which could have affected patient and physician responses. The 2020 UPLIFT survey revealed substantial patient burden, treatment dissatisfaction, and potential undertreatment with systemic therapy in PsO, including for patients with limited skin involvement, involvement in special areas, or bothersome symptoms such as itching and pain. Many patients with PsO but without a PsA diagnosis experienced musculoskeletal symptoms and may be candidates for referral to a rheumatologist. Also, QOL impairment was higher in patients with a positive depression screen, suggesting a need for further mental health evaluation. Overall, these findings underscore an opportunity for enhanced patient-dermatologist relationships to improve outcomes and address persistent unmet needs of patients with PsO across the disease severity continuum. Potential topics for future analysis include further exploration of the disconnect between patient and physician perceptions to optimize management of PsO and PsA. Data Availability.
