Abstract

Objective There is no proven primary care treatment for patients with medically unexplained symptoms (MUS). We hypothesized that a long-term, multidimensional intervention by primary care providers would improve MUS patients' mental health.Design Clinical trial.Setting HMO in Lansing, MI.Participants Patients from 18 to 65 years old with 2 consecutive years of high utilization were identified as having MUS by a reliable chart rating procedure; 206 subjects were randomized and 200 completed the study.Intervention From May 2000 to January 2003, 4 primary care clinicians deployed a 12-month intervention consisting of cognitive-behavioral, pharmacological, and other treatment modalities. A behaviorally defined patient-centered method was used by clinicians to facilitate this treatment and the provider-patient relationship.Main outcome measure The primary endpoint was an improvement from baseline to 12 months of 4 or more points on the Mental Component Summary of the SF-36.Results Two hundred patients averaged 13.6 visits for the year preceding study. The average age was 47.7 years and 79.1% were females. Using intent to treat, 48 treatment and 34 control patients improved (odds ratio [OR]=1.92, 95% confidence interval [CI]: 1.08 to 3.40; P=.02). The relative benefit (relative "risk" for improving) was 1.47 (CI: 1.05 to 2.07), and the number needed to treat was 6.4 (95% CI: 0.89 to 11.89). The following baseline measures predicted improvement: severe mental dysfunction (P<.001), severe body pain (P=.039), nonsevere physical dysfunction (P=.003), and at least 16 years of education (P=.022); c-statistic=0.75.Conclusion The first multidimensional intervention by primary care clinicians led to clinically significant improvement in MUS patients.

  • Only two studies have explicitly considered repeated service use in MUS, and only one identified those frequently attending for 2 years.

    “Only two studies have explicitly considered repeated service use in MUS, however, and only one identified those frequently attending for 2 years. 16,17”

    From Cognitive behaviour therapy for long-term frequent attenders in primary care: A feasibility case series and treatment development study (2016) · cites this paper as [17]

    The Subject Identification section says the study identified patients with MUS who had at least eight visits per year for the preceding two years. The paper does not establish that only two studies considered repeated service use in MUS, or that this was the only one to identify frequent attenders over two years. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • The remaining six studies were randomized by patient.

    “and the remaining six were randomized by patient (Brown 2001; McLean 2004; Smith 2006; Song 2005; Sorlie 2007; Wolf 2008).”
  • In Smith 2006, the intervention group was more likely to have improved SF-36 mental component summary scores after 12 months than control patients.

    “Similarly, the intervention group in Smith 2006 were more likely to have improved SF‐36 mental component summary and physical disability scores after 12 months than control patients.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
