Introduction

 

In the United States and Canada, musculoskeletal complaints can often comprise up to 25 percent of a primary care physicians’ daily practice,1-3 while some Texas family physicians feel their training in orthopedics and sports medicine may not have adequately prepared them. Previous studies have reported on the limited training and lack of confidence in the diagnosis and management of common “office orthopedic” type problems by primary care physicians.4,5 Other studies have also reinforced the need to strengthen the musculoskeletal training received both in medical school and residency.1-7  

 

The purpose of this study is to examine the clinical competency and confidence levels of Texas family physicians with regards to musculoskeletal medicine.

Methods

 

A panel of three family physicians, two orthopedic surgeons, and two primary care sports medicine physicians were consulted on the survey design, selection of clinical cases and determination of the standard of care. A 56-item musculoskeletal survey, including three clinical case scenarios was then pilot-tested by a group of 18 family physicians both in the private practice and academic settings. The survey was refined after the pilot and mailed to a computer-generated, random selection of 1,800 members of the Texas Academy of Family Physicians. The survey was then returned by either standard mail or fax.

 

Information obtained in the survey included: medical school and residency graduation dates, type of residency, location and type of current practice, completion of a sports medicine fellowship and prior experience as a team physician. The survey also gathered information regarding the amount of orthopedic and sports medicine training during residency. The respondents were asked to rate the quality and the quantity of the orthopedic and sports medicine training they received. 

 

The final component of this survey consisted of three clinical cases: lateral ankle sprain, lateral epicondylitis (tennis elbow), and knee meniscal injury. Participating physicians were asked specific questions using a five-point Likert scale for each case regarding the initial evaluation and treatment, activity level, rehabilitation and return to play issues. The data was analyzed with Analyse-itTM (1997-2002 England, United Kingdom).

Results

 

Two hundred twelve Texas family physicians completed and returned this survey with a response rate of 11.55 percent. The majority of respondents (86 percent) graduated from residency over the past 20 years. Most graduates were from either a community-based (57 percent) or university-based (36 percent) residency program. The practice type consisted of: group practice (42 percent), multi-specialty (24 percent), solo (19 percent), and academic (15 percent). The practice location varied from suburban (44 percent), urban (29 percent), and rural (27 percent).

 

A total of four respondents (2 percent) had completed fellowship training in sports medicine, and 37 percent reported prior experience as a team physician. Only 37.1 percent of respondents agreed or strongly agreed that their orthopedic training had prepared them for their current practice. Many physicians (63.2 percent) felt that more time was needed for orthopedics during their residency training. In regards to sports medicine, only 23 percent of physicians felt that their sports medicine training had prepared them for their current practice, with many (63.8 percent) feeling that more time during residency training would have benefited them in their future practice.

 

The results of the clinical scenarios were as follows: 

 

Lateral Ankle Sprain Case

 

Most physicians sampled (98 percent) recommend RICE (rest, ice, compression, and elevation) when dealing with an acute ankle sprain and 96 percent would prescribe a non-steroidal anti-inflammatory (NSAID) in the acute setting. More than half (62 percent) would order an initial ankle radiograph, while approximately 47 percent would consider referring this injury to an orthopedic surgeon for further evaluation. Most (89 percent) physicians surveyed would allow these patients to ambulate with pain as the limiting factor and many would offer rehabilitation exercises to patients either in the office or outpatient setting. Most (93 percent) would allow return to play when the pain had resolved and the patient demonstrated full range of motion and strength.

 

Lateral Epicondylitis (Tennis Elbow)

 

During initial treatment, 79 percent of surveyed physicians would recommend RICE for this condition. A counter-force brace was used by 80 percent of physicians and again a large number (98 percent) of physicians would prescribe a NSAID in this situation. One hundred twenty-three (58 percent) physicians would offer a corticosteroid injection of the lateral epicondyle region for this condition. In terms of activity level, 90 percent of physicians would decrease overall level of activity with pain as the limiting factor. Some physicians would review the patient’s tennis technique, and 33 percent would recommend alternative exercises to maintain conditioning. Over three-quarters of physicians would teach home exercise and/or stretches in the office and 5 percent would refer to a physical therapist for further management.

 

Meniscal Injury

 

As initial treatment, 79 percent of physicians in this sample would recommend RICE. Most (98 percent) would prescribe a NSAID, and 40 percent report that they would never recommend intra-articular injection of a corticosteroid. The majority of physicians (84 percent) would refer this condition to an orthopedic surgeon for further evaluation. The use of imaging procedures consisted of plain radiographs (82 percent) and magnetic resonance imaging (86 percent). One hundred sixty-one (76 percent) of these physicians would reduce running distance with pain as the limiting factor and 92 percent would recommend alternative exercises to maintain fitness. Approximately 12 percent of these physicians would review training techniques and biomechanical factors with these patients. Nearly half would recommend some type of rehabilitation using a physical therapist.

 

Discussion

 

Family physicians in Texas feel that more needs to be done both to increase and strengthen the amount of musculoskeletal training they receive during medical school and residency. A recent study from the University of Pennsylvania School of Medicine reached similar conclusions, reporting that despite the continued need for musculoskeletal education, there may be a marked disparity between the amount of musculoskeletal problems seen in practice, and the adequacy of preparation gained in medical school and residency.3 This article revealed that 82 percent of medical and surgical residents — from 37 different medical schools — failed to demonstrate basic musculoskeletal competency on a validated musculoskeletal knowledge exam.3 In an earlier study of family physicians from North Carolina, 51 percent of the respondents reported that their training in orthopedics had been inadequate for their current practice.8 Several studies have also identified deficiencies in the orthopedic physical examination skills of medical students and primary care physicians.9,10

 

Despite the fact that Texas family physicians feel they need more orthopedic and sports medicine training, the study sample performed well overall in regards to managing three common conditions when compared to the “expert panel.” However, there were a few findings that deserve mention. A large number of physicians prescribe anti-inflammatory medication in the acute setting to help control pain associated with injury. These medications may lead to increased acute swelling within the injured tissues. A consideration should be made to use a medication such as acetaminophen during the first 24-48 hours after injury to help control pain without the associated risks of increasing swelling. Anti-inflammatory medications may also inhibit the initial healing response by limiting “healthy” inflammation and the influx of inflammatory mediators that are needed for tissue repair and remodeling (level 3 evidence).11 Anti-inflammatory medications also carry some risk of adverse effects (gastrointestinal bleeding and renal damage) and associated costs if used on a chronic basis by our patients.

 

This study sample also was very likely to refer many of these conditions for further evaluation by specialists but it is unclear from the study the reasons for these referrals. Many physicians refer when the patient is not responding to the initial treatment as expected or because the injury is more severe than usual. Others may refer due to a lack of confidence in proper diagnosis and management of some musculoskeletal conditions or because of liability concerns. There are also times when patients or their families request specialty evaluation when it may not be necessary. It is possible that as musculoskeletal knowledge and confidence increase over time that primary care physicians may be able to care for many of the non-operative musculoskeletal conditions encountered in their daily practices, avoiding unnecessary testing and referrals.

Many physicians in this study sample were reluctant to or did not educate their patients about proper rehabilitative exercises when injured. Similarly, they did not offer ways to maintain cardiovascular conditioning while attempting to recover from injury. When dealing with the injured athlete or ‘weekend warrior’ it is preferable, when possible, to allow the athletes to modify the activity to allow recovery or develop other ways to maintain conditioning. Lower impact activities such as swimming pool therapy, elliptical trainer or stationary bicycle can often accomplish these goals while still allowing the patient to stay active.

 

A similar study by Glazier et al4 has determined that Ontario primary care physicians managed three clinical case scenarios fairly well but were more likely to prescribe NSAIDs inappropriately, order unnecessary tests and inappropriate referrals, as well as not prescribing exercises frequently enough. They concluded that primary care physicians need further exposure to musculoskeletal problems, both during medical school and in residency training.

 

Increasing the amount of training and exposure at the medical school level is the first step in improving knowledge in musculoskeletal medicine. Creating a foundation of knowledge that can be built upon and refined during post-graduate training are key components. Courses like gross anatomy should emphasize functional and surface anatomy as well as the biomechanics of joints and how these areas relate to patient diseases or injuries. Schnirring et al summarized in 1999 that only 12 percent of Canadian medical schools require clinical exposure to musculoskeletal medicine, and even less time is devoted during the preclinical years.1 

 

Clinical training should be shifted from the inpatient orthopedic setting to a more clinically-oriented office approach when possible. This would allow students and residents to focus on refining history taking, physical exam skills, reviewing surface anatomy, as well as outpatient skills such as splinting, casting, injection techniques and patient education.

At the resident level, those interested in gaining more experience in casting, splinting, joint injections and musculoskeletal examinations can look for further training during elective time or during an orthopedic and sports medicine elective rotation. Some programs in Texas offer elective time in sports medicine to those residents interested in furthering their skills or who may be interested in a one-year sports medicine fellowship after residency. Residency program directors should investigate the possible benefits of adding a sports medicine clinic to the residency program. Residents should also be encouraged to look for opportunities to become team physicians for local athletic programs, to attend sports medicine clinics, and to become involved with the youth athletic community. This type of exposure can provide valuable hands-on opportunities and experiences that will enhance and build confidence in managing musculoskeletal injuries. 

Upon completion of training, primary care physicians can seek out continuing medical education opportunities to address the musculoskeletal deficiencies of their training. Prior reports have emphasized that CME is one of the best ways to improve knowledge and confidence in managing musculoskeletal disorders.5 Organizations like the American Academy of Family Physicians provide yearly comprehensive review courses dealing with the primary care management of musculoskeletal injuries that can enhance knowledge and improve the quality of patient care. Primary care physicians, residents and medical students can also become involved in organizations like the Texas Chapter of the American College of Sports Medicine, which offers an annual meeting and opportunities to further enhance their musculoskeletal knowledge or even present sports medicine research or clinical cases.

The goal of Texas family physicians should be to strengthen their diagnostic accuracy through proper history and physical exam skills, decreasing unnecessary medication use and the inappropriate use of testing/radiological studies. Often expensive MRI and other diagnostic tests are unnecessary and are used in place of a good history and physical examination. Physicians dealing with musculoskeletal problems should be competent to know both when and when not to refer to specialists in orthopedics and sports medicine.

 
 

Some areas of limitations of this study include a poor response rate, which could have been improved by follow-up mail to non-respondents, or the use of a Web-based or e-mail type survey. There may have also been some response bias in physicians not comfortable in managing these musculoskeletal conditions and therefore not returning the survey. The respondents were also not able to explain some of their answers, which may have provided some useful information regarding patient care. Also those surveyed may have answered the clinical cases differently from how they actually practice because of the Hawthorne effect (knowing they were participating in a research project). 

 

In summary, the findings of this study reveal that Texas family physicians would like further training in musculoskeletal medicine to help prepare them for the types of patients they encounter on a daily basis. Similar to previous studies, this study sample may have over prescribed anti-inflammatory medication, underutilizing cross-training activities to maintain cardiovascular fitness and may have ordered unnecessary radiological procedures and referrals to specialist. Further research is needed to help shape the education and curriculum of our medical students and residents in musculoskeletal medicine.
