ReviewCarbapenems and monobactams: imipenem, meropenem, and aztreonam.
Imipenem and meropenem, members of the carbapenem class of beta-lactam antibiotics, are among the most broadly active antibiotics available for systemic use in humans. They are active against streptococci, methicillin-sensitive staphylococci, Neisseria, Haemophilus, anaerobes, and the common aerobic gram-negative nosocomial pathogens including Pseudomonas. Resistance to imipenem and meropenem may emerge during treatment of P. aeruginosa infections, as has occurred with other beta-lactam agents; Stenotrophomonas maltophilia is typically resistant to both imipenem and meropenem. ⋯ It is often used in combination therapy for mixed aerobic and anaerobic infections. Approved indications for its use include infections of the urinary tract or lower respiratory tract, intra-abdominal and gynecologic infections, septicemia, and cutaneous infections caused by susceptible organisms. Concurrent initial therapy with other antimicrobial agents is recommended before the causative organism has been determined in patients who are seriously ill or at risk for gram-positive or anaerobic infection.

Potential effect of authorization bias on medical record research.
To analyze the influence of recent changes in Minnesota statutes that generally require prior authorization for use of medical records for research from patients who received medical care after Jan. 1, 1997. ⋯ These data demonstrate that laws requiring written authorization for research use of the medical record could result in substantial biases in etiologic and outcome studies, the direction and magnitude of which may vary from topic to topic. Clinicians should be prepared to enter the discussion to help inform patients and legislators of the potential hazards of laws that restrict access to medical records for research purposes.
