Improve your practice with these 10 primary care recommendations

 1 Avoid imaging studies in early acute low back pain without red flags.

Both the AAFP and the American Society of Anesthesiologists recommend against routine X-rays, magnetic resonance imaging, and computed tomography (CT) scans in the first 6 weeks of acute low back pain (LBP).8,9 The American College of Emergency Physicians (ACEP) recommends against routine lumbar spine imaging for emergency department (ED) patients.10 In all cases, imaging is indicated if the patient has any signs or symptoms of neurologic deficits or other indications, such as signs of spinal infection or fracture. However, as ACEP notes, diagnostic imaging does not typically help identify the cause of acute LBP, and when it does, it does not reduce the time to symptom improvement.10

2 Prescribe oral contraceptives on the basis of a medical history and a blood pressure measurement. No routine pelvic exam or other physical exam is necessary.

This AAFP recommendation11 is based on clinical practice guidelines from the American College of Obstetricians and Gynecologists (ACOG) and other research.12 The ACOG practice guideline supports provision of hormonal contraception without a pelvic exam, cervical cancer (Pap) testing, urine pregnancy testing, or testing for sexually transmitted infections. ACOG guidelines also support over-the-counter provision of hormonal contraceptives, including combined oral contraceptives.12

3 Stop recommending daily self-glucose monitoring for patients with diabetes who are not using insulin.

Both the AAFP and the Society for General Internal Medicine recommend against daily blood sugar checks for people who do not use insulin.13,14 A Cochrane review of 9 trials (3300 patients) found that after 6 months, hemoglobin A1C was reduced by 0.3% in people who checked their sugar daily compared with those who did not, but this difference was not significant after a year.15 Hypoglycemic episodes were more common in the “checking” group, and there were no differences in quality of life. A qualitative study found that blood sugar results had little impact on patients’ motivation to change behavior.16

4 Don’t screen for herpes simplex virus (HSV) infection in asymptomatic adults, even those who are pregnant.

This AAFP recommendation17 comes from a US Preventive Services Task Force (USPSTF) Grade D recommendation.18 Most people with positive HSV-2 serology have had an outbreak; even those who do not think they have had one will realize that they had the symptoms once they hear them described.18 With available tests, 1 in 2 positive results for HSV-2 among asymptomatic people will be a false-positive.18

A 2006 analysis of inpatient lab studies found that doctors ordered an average of 2.96 studies per patient per day, but only 29% of these tests contributed to management.

There is no known cure, intervention, or reduction in transmission for infected patients who do not have symptoms.18 Also, serologically detected HSV-2 does not reliably predict genital herpes; and HSV-1 has been found to cause an increasing percentage of genital infection cases.18
