How Would You Describe Your Most Important Priorities When Evaluating A Patient?

It is a very challenging, yet rewarding experience to provide an excellent patient evaluation. Every patient is very unique and has many different facets that influence their presentation. I think it is extremely important to get an accurate and detailed history regarding the pain related problem, but also obtain an overall global picture of the patient’s situation. It’s a high priority to try to understand the patient’s living, social and family environment to better understand their responses to their pain-related problem. This very thorough and global evaluation also helps direct resources in the most appropriate and effective direction following the evaluation.

What Types Of Activities Or Hobbies Are You Interested In Outside Of Medicine?

I am a big believer in a balanced lifestyle. I like to balance the combination of family life, personal health, social life and professional life. A balanced lifestyle is challenging, since each of these areas are important priorities, and it takes discipline to make time for each one of these.

I also spend a tremendous amount of time volunteering with different medical societies. I hold, and have held, a number of different official positions within the California Medical Association (CMA), American Medical Association and the San Diego County Medical Society. I have recently been the president of the San Diego County Medical Society and currently am one of the trustees from San Diego representing our medical Society to the California Medical Association. In addition to being on the Board of Trustees for the CMA I am also on the board of directors for the CMA Foundation. This is a statewide nonprofit organization that aspires to provide greater access to public health projects and services among other contributions to the public well-being. I represent my national specialty organization, the American Academy of Pain Medicine, to the American Medical Association. I go to regular meetings to voice opinions and try to support greater access to health care for all Americans. I also spend a lot of time on legislative issues with frequent visits to our legislators from San Diego. I spent a fair amount of time in Sacramento and Washington DC promoting good public health causes.

I am especially attentive to my 3 children who are all pursuing their own dreams, including medicine and dentistry.

Other hobbies include golf, tennis and a variety of other sports. I work out on a regular basis. I am one of the 80% of all Americans who have back problems. If I do not exercise, my back becomes symptomatic, but if I exercise regularly my back does amazingly well. My personal experiences drive my encouragement for people to exercise, be active and live a healthy lifestyle.

If I have any free time after that, I enjoy socializing with friends and travel. I certainly keep very busy, but I am very grateful for a full and satisfying life.

How would you describe your most important priorities when evaluating a patient?

When I evaluate a patient, I focus on the whole patient in order to develop the most appropriate treatment plan. I begin with a thorough evaluation in regard to their pain symptoms as well as their medical history and other symptoms. I then seek to understand the patient’s priorities by using a biopsychosocial model. With this approach, the emphasis is placed on determining what is important to the patient in terms of how they feel, what they are able to do functionally and how that fits into their belief system. Key components are the physical, social, psychological and spiritual domains. After a thorough physical examination and review of supporting studies, a detailed explanation of the patient’s pain is provided and then a comprehensive treatment plan is developed. This may include therapies, exercise, medications, psychological support, state of the art interventions and often coordinated care with other specialties. Reduction in pain, increase in function and an overall improvement in quality of life are the goals with each patient.

What types of activities or hobbies are you interested in outside of medicine?

I enjoy hobbies of jogging, basketball, cooking, skiing, traveling, and time with family.

How would you describe your more important priorities when evaluating a patient?

I have a number of priorities when I first meet a patient. The first important step is to establish my role as a consultant to the patient for their health conditions. A trusting relationship, with open and honest communication, is fundamental; patients must trust that the information being provided is for their benefit. The second is the need for as an accurate a diagnosis as possible. The better the diagnosis, the more likely treatments will be successful. I also believe that patients should be treated as a whole person. Pain conditions can have significant impacts on people’s relationships, functioning, sleep, mood and essentially all aspects of one’s life, therefore I recommend patients participate in a comprehensive plan that incorporates as many tools to improve a patient’s life as possible. Tools may include procedures, medications, physical rehabilitation and behavioral approaches. All patients should have access to the available options to reduce pain and ease suffering.

What types of activities or hobbies are you interested in outside of medicine?

Outside of my practice, I spend as much time with my family in the outdoors as possible. We enjoy hiking, camping and sailing. As a youth I became an Eagle Scout and I am now able to share this knowledge with my boys who are both participating in the scouting program.

PA Davis started his career utilizing his general medicine training by practicing in the specialty of Family Medicine. Prior to his PA training he had extensive opportunities researching pre-clinical cardiac surgical approaches and investigative medical devices. He was fortunate to be part of the pre-clinical assessment of the DaVinci robot for robotic assisted surgery that has now been approved for human use.

After a couple of years of evaluating a wide variety of conditions in Family Medicine, he recognized that the impact of helping patients with pain was transformative for the patient and rewarding for the clinician. He transitioned his practice into full time pain management and mentored under national pain experts. He has now specialized in pain management nearly 10 years and has served patients with pain conditions in both California and New York. His experience in New York involved providing pain care within a state-of-the-art oncology center. PA Davis has brought a wealth of expertise to Pacific Pain Medicine.

PA Davis has focused on comprehensive care and appropriate medication management options. As a team member, PA Davis frequently coordinates care with other providers on our clinical team, referring providers and case managers. He has collaborated on developing protocol based approaches to patients who may be at elevated risk for medication abuse, but still need assistance for management of pain. PA Davis’ approach to patients is consistent, caring, and uniquely developed for each patient. He stresses the importance of the outcome of various treatments as justification for ongoing therapy. He endorses a full spectrum of treatments, including advanced pain therapies such as spinal cord stimulation and intrathecal drug delivery.

PA Davis has received exceptionally positive feedback from his patients and peers, some of whom have posted wonderful reviews on online review websites.

Meet PA Davis

How would you describe your most important priorities when evaluating a patient?

My experiences as a patient and as the family member of a loved one as a patient have significantly shaped how I interact and care for my patients as a healthcare provider. First and foremost, I want the new and established patient to know that we at Pacific Pain Medicine, as a team, want to help them. From the first call to set up an office visit to the last visit and everything in between, our goal is to help our patients. That is why we are in this field.

I feel that we accomplish this by listening to the patient, and how their pain affects them, their life, the lives of their friends and family members. Providing a thorough history and physical exam, working up the pain(s) with the goal of providing an actual diagnosis is very important. Once there is a diagnosis, the next step is empowering the patient with education on their condition, the reasonable treatment options available and maybe most importantly- realistic expectations.

What types of activities or hobbies are you interested in outside of medicine?

When I am not working at Pacific Pain Medicine, I enjoy spending time with my family. We like to take advantage of what we have here in Southern California and get out for hikes, camping and time at the beach. I personally enjoy disc golfing and home brewing beer any chance I get.

Meet PA Owusu

How would you describe your more important priorities when evaluating a patient?

My most important priority when evaluating a patient is that they leave our office understanding the potential diagnoses causing their pain (if there is one). If they can conceptualize why they are experiencing their symptoms, then perhaps our management or treatment plan will make more sense to them. They also feel as if they are a part of the treatment plan rather than just the recipient. I really do love being the first one to diagnose their condition accurately, then offer appropriate options for treatment.

What types of activities or hobbies are you interested in outside of medicine?

Traveling, basketball, bicycling, and music.
