Psoriatic disease, which includes psoriasis and psoriatic arthritis (PsA), requires people with both conditions to seek out health care from both rheumatologists and dermatologists in order to successfully manage their diseases. With the help of dual dermatology-rheumatology clinics, this has gotten even easier.

Dual dermatology-rheumatology practices combine input from and appointments with both rheumatologists and dermatologists in one clinical setting and there is a vital need for them.

The combination of these two specialties in one place enhances patient care and outcomes to increase patient participation in their own care and can leave both parties satisfied with the level of care being given.

Read more about these combined practices, why they are necessary, their impact, and the advantages and disadvantages of these practices. 


There are more than 8 million people in the United States affected by psoriasis, according to the National Psoriasis Foundation, and up to 30% of people with psoriasis—nearly 1 in 3—will eventually go on to develop psoriatic arthritis.

Psoriasis and PsA both result from an overactive immune system where chronic inflammation will attack the skin and the joints. Psoriasis is known for causing a buildup of skin cells that can range from localized patches to complete body coverage.

PsA causes inflammation in the joints—specifically in the places where tendons and ligaments meet bone. Neither condition is curable, but both are treatable, often with some of the same therapies.

Having two different medical disciplines seeing the same person at the same time allows both doctors and their patients to discuss all concerns and options in one place and at one time. In addition to saving time, it allows for all health providers to be on the same page when it comes to managing psoriatic disease and appropriate patient care.

One-Stop Experience

For someone living with both psoriasis and PsA, the combined clinic experience can be like one-stop shopping. This way you are not running around to multiple appointments, or having to take multiple days away from work or family obligations, or looking for child care, just to attend to medical appointments and prioritize your health.


Dermatology, the branch of medicine concerned with the diagnosis and treatment of skin disorders, seems to cross with just about every medical specialty.

It has the greatest connection to rheumatology— a medical specialty concerned with the diagnosis and management of autoimmune, inflammatory, or other musculoskeletal conditions commonly known as rheumatic diseases.

Many types of skin problems can occur with rheumatic diseases like psoriatic arthritis (PsA) and rheumatoid arthritis (RA). RA is a chronic rheumatic disease that affects mainly the joints, but it can also affect a wide variety of other body systems, including the eyes, skin, heart, and kidneys.

Many skin conditions share similar symptoms to rheumatic conditions and a growing list of similar therapies like disease-modifying anti-rheumatic drugs (DMARDs), biologic therapies, and biosimilar drugs.

With this obvious overlap, there is a necessity for these combined specialty practices. Many major medical centers in the United States understand this, as they continue to combine diagnosis and treatment of PsA and other interconnected skin and musculoskeletal conditions.

Technology Enhancement

Many of the goals and practices of combined dermatology-rheumatology clinics have become even more enhanced by technology—like electronic health records and telemedicine.

These methods have made information sharing between the specialties easier and quite effective, which ultimately translates into improved patient outcomes, especially as it pertains to enhanced quality of life for people living with psoriasis, PsA, and other overlapping skin and rheumatic diseases.


The possibility and effectiveness of dual joint dermatology-rheumatology clinics were demonstrated by researchers at a psoriasis and psoriatic arthritis clinic (PPAC) in Athens, Greece.

From December 2018 to January 2019, the doctors at the PPAC clinic saw 185 patients who had both psoriasis and PsA, the majority of which had severe psoriasis and were using biologic therapy treatment. And among these patients, comorbidities were high. 

The term comorbidity refers to more than one disease in the same person. Psoriasis and PsA are linked to many comorbidities, including heart disease, depression, and type 2 diabetes

Most of the patients at the PPAC reported being highly satisfied with dual specialty practice compared to going to two separate clinics, and most agreed that the collaboration between dermatologists and rheumatologists was vital to their care. The doctors acknowledged the combined team approach improved patient care quality and clinical outcomes.

Another study, this one reported in 2018 in the journal Clinical Rheumatology aimed to determine whether integrated management for psoriatic disease could achieve certain goals, including early diagnosis, better outcomes for skin and musculoskeletal symptoms, and overall patient quality of life.

After a 48-week period, the researchers found the dual specialty practice could yield prompt diagnoses and best treatment approaches, which was evidenced in the significant improvement of skin and joint symptoms and in patient quality of life. 

Advantages and Disadvantages

Combined care clinics offer many advantages to patient care and medical practice. They will also have their disadvantages. 

A 2012 report from a dual dermatology and rheumatology clinic in Vancouver, British Columbia reported on the doctor-patient combined practice experience. The report’s authors noted the combination of specialists was helpful in evaluating patients with skin and multiple systemic (all-over) symptoms offering a comprehensive treatment approach for people with both psoriasis and PsA.

A 2015 systemic review of the literature on psoriasis and PsA found the effectiveness of therapy improved in combined dermatology-rheumatology clinics. Additionally, patient satisfaction was higher with the combined practice than with separate visits. 

The downside—as reported by many of the study participants—was the scheduling wait time and the wait at the clinic to be seen. Only 41% of the patients were seen at their actual appointment time.

Productivity can be another challenge for dual practice clinics. For example, dermatologists are used to seeing multiple patients over a workday, while rheumatologists see about half that amount.

Cost is yet another concern. People who participate in combined clinics may see higher medical costs because their visits are more complex, or they may see two bills—one for each medical provider involved in their care.

Fortunately, costs can be offset by the benefits of avoiding duplicative appointments, reduced miscommunication between departments, and timely access to specialist care.

Pediatric Dermatology-Rheumatology Clinics

Much like adult conditions, there can overlap in rheumatic and dermatologic conditions in children. Pediatric joint and skin conditions tend to be harder to diagnose and treat and will require the expertise of both rheumatologists and dermatologists.

With combined practices, doctors can provide necessary optimized care and parent and child education at one location and at one time.

A retrospective analysis reported in 2018 in the journal Rheumatology aimed to analyze the quality of care given to pediatric patients seen in a combined dermatology-rheumatology practice.

The researchers looked at patient demographics, common diagnoses over a two-year period, and the benefits of having a combined treatment approach. For the analysis, researchers relied on care records and informal feedback from treaters, parents, and their patients.

They were able to conclude the combined dermatology-rheumatology experience was a much more useful resource and experience over visiting multiple specialties.  Benefits of the pediatric dermatology-rheumatology clinic experience included:

  • Quick access to rheumatologic and dermatologic care and diagnosis, and appropriate disease management
  • Reduced clinic visits and less time spent at appointments
  • Improved patient education and support

There is a critical shortage of pediatric rheumatologists in the United States, which means parents of children with rheumatic conditions are traveling to clinics that are far away, imposing time burdens and high monetary costs on these families. And while telemedicine can help filter some of the cost and time burden, it doesn’t tackle the need for in-person care.

With dual specialty practices, families can go to one appointment and have their healthcare needs met in one place, which translates to better health outcomes for pediatric patients, which satisfies everyone involved.

Unfortunately, it does not come as a surprise that there are few combined pediatric dermatology-rheumatology practices in the United States, including one which is out of the Stanford University Health system in Palo Alto, California. But hopefully, there will be change on the horizon as the need and awareness become greater for these types of care facilities.

 A Word From Verywell

Combined dermatology-rheumatology practices are not a new concept. In fact, you can find them at many major academic institutions in the United States and around the globe. And most have focused primarily on the treatment of psoriasis and psoriatic arthritis.

There are other types of combined clinics, including in functional medicine and complex medical care, in addition to rheumatology. They can be found at many great medical institutions across the United States, including at the Cleveland Clinic in Cleveland, Ohio, and at Johns Hopkins Medical Center in Baltimore, Maryland. 

The benefits of using dermatology-rheumatology dual clinics are many, including the consistent dialogue between healthcare providers. But in the end, it will come down to you as the patient, or as a parent advocating for your child, being at the center of it all.

Do your research and advocate to get access to the best and most appropriate care in the way that it fits into your life—regardless of the structure of that care.
