Does negative testing reassure patients?

Probably not according to a recent study (JAMA Intern Med, published online Feb 25, 2013, dpi:10.1001/jamainternmed.2013.2762).

In this study, the authors systematically reviewed the literature and, after screening 9742 studies, identified 14 randomized controlled trials (n=3828 patients) which met inclusion criteria, including the following:

  • Randomized control trial
  • Adult participants with symptoms indicating a low probability of serious disease

Studies were excluded if they were not published in a peer-reviewed journal or if they were undertaken in a tertiary care setting.  Eight trials involved diagnostic testing for dyspepsia (mainly endoscopy), three involved radiography for back pain, and the other three included testing for chest pain, headache and palpitations.  Long-term follow-up varied from 4 to 18 months.

Key Findings:

  • Patients’ illness concern (odds ratio 0.87 in three trials) and anxiety (standardized mean difference 0.06 [-0.16 to 0.28] in two trials) were not reduced in the short or long term.
  • No overall long-term effect on symptom persistence was noted (odds ratio 0.99)


  • The authors examined only reassurance for patients, not for physicians.
  • Participants were not blinded
  • Overall, small number of study participants

In the discussion, the authors note that observational studies “suggest that illness concerns reappear within hours of receiving a normal (negative) test  result.”

For pediatric gastroenterologists, the conclusions from this article add another wrinkle when deciding how much workup is indicated for conditions like recurrent abdominal pain.  Previous data indicate that maternal anxiety is the most consistent predictor of outcome for recurrent abdominal pain (Acta Paediatr 2007; 96: 697-701); this study does not address whether patient proxies are reassured by negative testing.  And, other studies have shown that patients rate their care higher after diagnostic testing (Don’t miss the gorilla! | gutsandgrowth).

As a fellow, I was told: “Don’t just do something, stand there” from Bill Balistreri; he also recommended avoiding the mentality of “Scope first, think second.” While this current study suggests that there is a lack of long-term benefit when testing is done primarily for reassurance, convincing families that their child does not need testing is often difficult.
