[The placebo problem]

W Reinhard

    Methods and Findings in Experimental and Clinical Pharmacology
    |January 1, 1981
    PubMed
    Summary
    This summary is machine-generated.

    Spontaneous disease remission, not just the doctor-patient relationship, significantly influences placebo effects in clinical trials. Understanding this natural course is crucial for accurate controlled trial design and analysis.

    Area of Science:

    • Medical Research Methodology
    • Clinical Trial Design
    • Pharmacology

    Context:

    • The traditional view of placebo response often overemphasizes the doctor-patient relationship.
    • Spontaneous remission of illness, a natural phenomenon, plays a critical role in observed treatment outcomes.
    • Historical observations, such as Siemens' 1939 work, highlight the significance of spontaneous disease progression.

    Purpose:

    • To re-evaluate the factors contributing to placebo response in clinical trials.
    • To emphasize the importance of spontaneous disease development as a confounding factor.
    • To provide guidelines for conducting and analyzing placebo-controlled trials.

    Summary:

    • This study posits that spontaneous remission is a key driver of placebo effects, challenging the sole reliance on the doctor-patient relationship.

    Related Experiment Videos

  • It draws an analogy between spontaneous illness development and the controlled trial methodology.
  • The paper discusses the conditions, control substances, and decision criteria for implementing placebo-controlled trials.

    • Impact:

    • Reframes the understanding of placebo response in clinical research.
    • Advocates for rigorous controlled trial methodologies that account for natural disease progression.
    • Ensures that the analysis of placebo-controlled trials is conducted ethically and does not harm patients.
