Perspectives on the value of the clinical exam for your patients with work-related medical conditions

Issue: BCMJ, vol. 65, No. 10, December 2023, Pages 386,388 WorkSafeBC

When I started my medical training in 1984, the general understanding was that clinical history contributed about 70% to establishing a diagnosis, with physical examination and investigations contributing about 20% and 10%, respectively. Since then, remarkable advancements in medical imaging (MRI became widely available only in the early 1990s), other rapidly advancing technologies, practice pressures, and virtual care have all influenced the role of the physical exam.

WorkSafeBC depends on external information to adjudicate a worker’s claim and relies on the information physicians submit to support the worker’s treatment and recovery from a workplace injury or illness. When a WorkSafeBC medical advisor (a physician) reviews claims, they also review the examination findings from attending physicians. Missing or incomplete findings can impact a worker’s entitlement to WorkSafeBC benefits such as physiotherapy and expedited assessments, investigations, and surgery. Missing information also makes it difficult to identify safe options for a graduated return to work, which can imperil a worker’s livelihood.

Looking closely at an injury with persistent symptoms

Imagine the following patient comes to see you for an injury that occurred at work. Bob is a 54-year-old construction worker who has been your patient for over 20 years. He notices a sharp pain in his right knee while straightening up after bending to the right to pick up a box of nails from the ground. Bob has seen you several times over the past 10 years for episodic pain in his knees; X-rays have shown mild osteoarthritis. Bob shrugs off the pain and completes his shift. Bob’s knee feels worse the following day, and he is able to schedule a telehealth visit in 2 weeks’ time. Bob submits a claim for his knee and informs his employer that he is not able to work due to the pain.

At a virtual assessment 2 weeks after the work incident, Bob reports that his knee feels a bit better. The swelling is almost gone, but descending stairs is uncomfortable. You diagnose a sprain/strain of the knee. Bob states that his knee is too sore to go back to work and wonders about taking more time off. You recommend 4 more weeks off work, physiotherapy, and an NSAID, and you schedule a follow-up telehealth visit. At follow-up, Bob informs you the swelling is gone and his knee feels mostly back to normal, except for occasional stabs of pain when squatting. When you suggest Bob try working, he asks why his knee is still sore and then asks if it is safe to resume working on ladders.

At this point, WorkSafeBC may have additional interventions to help Bob throughout his claim and return to work. To assist with interventions, WorkSafeBC medical advisors may be asked to provide opinions on the diagnoses provided by community physicians. Physical examination findings are an important part of the information reviewed. An accurate diagnosis ensures a worker receives appropriate treatment and receives the benefits to which they are entitled. Returning to your patient, Bob, stabbing knee pain persisting for 6 weeks is atypical for a sprain/strain. A physical examination can help differentiate between worsening osteoarthritis of the knee, meniscus injury, sprains of the cruciate or collateral ligaments, tendon injuries, and nontraumatic conditions. An accurate diagnosis with physical findings allows WorkSafeBC to find appropriate resources to help Bob recover and helps increase the chance of him preserving his livelihood.

Putting it together

Evidence shows that telemedicine is better suited to some patients than others and is most suitable for stable patients with chronic disease who have an existing relationship with their physician.[1] The Canadian Medical Protective Association calls the physical exam “a powerful tool” for improving the accuracy of diagnoses and cautions that “how you perform the physical exam, and how often you perform it, can change over time and become overly limited without you realizing the impact on patients.”[2] Performing a physical exam can also increase patients’ confidence in the physician and validate that they have been heard.

Above is the information needed to cite this article in your paper or presentation. The International Committee of Medical Journal Editors (ICMJE) recommends the following citation style, which is the now nearly universally accepted citation style for scientific papers:
Halpern SD, Ubel PA, Caplan AL, Marion DW, Palmer AM, Schiding JK, et al. Solid-organ transplantation in HIV-infected patients. N Engl J Med. 2002;347:284-7.

About the ICMJE and citation styles

The ICMJE is small group of editors of general medical journals who first met informally in Vancouver, British Columbia, in 1978 to establish guidelines for the format of manuscripts submitted to their journals. The group became known as the Vancouver Group. Its requirements for manuscripts, including formats for bibliographic references developed by the U.S. National Library of Medicine (NLM), were first published in 1979. The Vancouver Group expanded and evolved into the International Committee of Medical Journal Editors (ICMJE), which meets annually. The ICMJE created the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals to help authors and editors create and distribute accurate, clear, easily accessible reports of biomedical studies.

An alternate version of ICMJE style is to additionally list the month an issue number, but since most journals use continuous pagination, the shorter form provides sufficient information to locate the reference. The NLM now lists all authors.

BCMJ standard citation style is a slight modification of the ICMJE/NLM style, as follows:

  • Only the first three authors are listed, followed by "et al."
  • There is no period after the journal name.
  • Page numbers are not abbreviated.
