Delivery: Neonatal Group B Streptococcal (GBS) Disease

The American College of Obstetricians and Gynecologists recommends intrapartum antibiotics for women with rupture of membranes (ROM) for 18 hours or more to prevent neonatal Group B Streptococcal (GBS) infection (ACOG, 1993, 1996).

81 women with ROM≥18 hours from among all women with deliveries during the study period.

Medical records from two HMO hospitals (in which protocols similar to ACOG guidelines had been adopted) in San Francisco and Oakland, California, for women who delivered from January to June 1995.

88% received an antibiotic effective against GBS, 37% received antibiotics within 20 hours of ROM (median duration of ROM was 31 hours).

Asthma

Adult Asthma Care

Includes various components of asthma care consistent with prevailing standards of care.

Adults≥18 years old in a group of 393 adults and children diagnosed with asthma, from a sample of 2,024 patients of 135 providers.

Medical records from physicians’ offices, community health centers, and hospital outpatient facilities sampled from Maryland Medicaid claims data, 1988.

For each type of clinical setting, the study reports the average percentage of technical quality indicators for adult asthma that were not met. Each of the averages was located in the 40%–45% range. Between 5% and 35% of care was inappropriate.
