Pandemic-related health behavior: repeat episodes of influenza-like illness related to the 2009 H1N1 influenza pandemic.

The Houston Health Department (HHD) in Texas tracks influenza-like illness (ILI) in the community through its Influenza Sentinel Surveillance Program, which began in 2008. After the influenza A(H1N1) pandemic (pH1N1) in 2009, investigators sought to assess the feasibility of this program as a non-traditional data source for tracking and monitoring care-seeking activities. Through the process of characterizing and describing patients who had 'return visits', or who were considered the heaviest ILI-related care-utilizers, the investigators sought to understand the strengths and limitations of this data source.

Rubella monitoring in pregnancy as a means for evaluating a possible reemergence of rubella.

Objective: Although it is commonly accepted that rubella is well-controlled, a recent reemergence of both pertussis and measles might also predict a reemergence of rubella. This study was designed to estimate the current incidence of rubella exposure in pregnancy.

Study Design: This was a prospective, descriptive study, conducted in Houston, TX, at The Woman's Hospital of Texas.

Duration of intrapartum antibiotics for group B streptococcus on the diagnosis of clinical neonatal sepsis.

Background: Infants born to mothers who are colonized with group B streptococcus (GBS) but received <4 hours of intrapartum antibiotic prophylaxis (IAP) are at-risk for presenting later with sepsis. We assessed if <4 hours of maternal IAP for GBS are associated with an increased incidence of clinical neonatal sepsis.

Materials And Methods: A retrospective cohort study of women-infant dyads undergoing IAP for GBS at ≥37-week gestation who presented in labor from January 1, 2003 through December 31, 2007 was performed.

Screening for group B streptococcus: a private hospital's experience.

Objective: To assess the effect of universal screening and administration of intrapartum antibiotic prophylaxis to prevent early-onset neonatal GBS sepsis at a private tertiary care hospital since issuance of the 2002 CDC guidelines for preventing perinatal GBS disease.

Methods: Retrospective analysis of women delivering between January 1, 2003 and December 31, 2004 at a private tertiary care hospital in Houston, Texas. The percentage of women screened, GBS positive women receiving intrapartum antibiotic prophylaxis, and infants developing early-onset GBS sepsis were determined.

Improving influenza immunization in pregnant women and healthcare workers.

Objective: To evaluate the effect of several strategies to increase influenza immunization in a multispecialty clinic.

Study Design: Retrospective electronic database analysis of influenza vaccinations in a 6-year period at Kelsey-Seybold Clinic in Houston, Texas.

Methods: We evaluated immunization rates in pregnant women and healthcare workers during 6 influenza seasons (2003-2004 to 2008-2009) after implementing the following strategies for pregnant women: assessing baseline immunization rates for obstetric providers, followed by direct encouragement and behavior modeling; implementing standing orders for influenza vaccination in pregnancy; and offering vaccination training to obstetricians and nurses.
