A structured implicit abstraction method to evaluate whether content of counseling before prostate cancer screening is consistent with recommendations by experts

ObjectiveTo assess the content of counseling about prostate-specific antigen (PSA) screening. Guidelines recommend informed consent before screening because of concerns about benefits versus risks. As part of the professional practice standard for informed consent, clinicians should include content customarily provided by experts.Methods40 transcripts of conversations between medicine residents and standardized patients were abstracted using an instrument derived from an expert Delphi panel that ranked 10 “facts that experts believe men ought to know.”ResultsTranscripts contained definite criteria for an average of 1.7 facts, and either definite or partial criteria for 5.1 facts. Second- and third-year residents presented more facts than interns (p = 0.01). The most common facts were “false positive PSA tests can occur” and “use of the PSA test as a screening test is controversial.” There was an r = 0.88 correlation between inclusion by residents and the experts’ ranking.ConclusionCounseling varied but most transcripts included some expert-recommended facts. The absence of other facts could be a quality deficit or an effort to prioritize messages and lessen cognitive demands on the patient.Practice implicationsClinicians should adapt counseling for each patient, but our abstraction approach may help to assess the quality of informed consent over larger populations.
