Medication errors

A nice brief piece from NPR's Day to Day today, discussing outpatient medication errors--touches particularly on patient education and doctor/patient communication as key to addressing the issue.
Painkillers, sleeping pills and anti-anxiety drugs are being prescribed to out-patients in high doses, without the oversight of a doctor. A new study found that in the last 20 years there has been a 500 percent increase in the death rate from medication errors made at home. Medical contributor Dr. Sydney Spiesel discusses the data with Alex Chadwick.

July JMLA case

The latest JMLA case, Addressing Hemolysis in an Infant Due to Mother–Infant ABO Blood Incompatibility, is available in the July issue of the journal.

The question that this case focuses on: Is [intravenous immunoglobulin G] a safe and effective alternative to exchange transfusion in a premature infant with hemolysis and hyperbilirubinemia secondary to ABO incompatibility, who has failed phototherapy?

See the full-text of the case for definition of the medical terms, discussion of the search, and an analysis of the literature on this topic!

Adoption of electronic medical records

This week's MedlinePlus podcast from the National Library of Medicine covers data about provider and patient perceptions and adoption of EMRs; Rob Logan PhD is filling in for Dr Lindberg this week. The transcript of the podcast is here and the MedlinePlus topic page on EMRs is here.

Search challenge 10: strategies

Search challenge 10 examines the issue of how to decide on appropriate screening practices for breast cancer in a young woman whose grandmother developed breast cancer at a relatively young age.

A search that incorporates the main "components" of the question might look something like:
("Breast Neoplasms/diagnosis"[Majr] OR breast neoplasms/genetics[majr]) AND (inherited[tiab] OR familial[tiab] OR high risk[tiab] OR family history[tiab] OR grandmother[tiab] OR pedigree[tiab] OR second degree[tiab] OR heredity[tiab] OR hereditary[tiab]) AND (age factors[mh] OR risk[mh] OR predictive value of tests[mh] OR sensitivity and specificity[mh]) AND (diagnostic imaging[majr] OR mass screening[majr]) AND english[la] AND humans[mh] NOT (case reports[pt] OR letter[pt] OR comment[pt] OR editorial[pt])

A few good articles on the topics, drawn from PubMed and a Google search:
