Dataset Information

Hospitalizations for intussusception before and after the reintroduction of rotavirus vaccine in the United States.

ABSTRACT:

Objective

To determine whether hospital discharges for intussusception in children younger than 1 year have changed since the reintroduction of rotavirus vaccine in the United States.

Design

Serial cross-sectional analysis.

Setting

US hospitals.

Participants

Children younger than 1 year with a discharge diagnosis of intussusception identified in the Kids' Inpatient Database, a series of nationally representative data sets of pediatric hospital discharges in the United States with 4 available years prior to vaccine reintroduction (1997, 2000, 2003, and 2006) and 1 year after (2009).

Main exposures

Hospital discharge before vs after rotavirus vaccine reintroduction.

Outcome measures

Total number and rate of hospital discharges for infants younger than 1 year with a diagnosis of intussusception (International Classification of Diseases, Ninth Revision, Clinical Modification code 560.0).

Results

From 1997 to 2006, there was no change in the total number of hospital discharges for intussusception, with a small decrease in the rate of intussusception discharges (41.6 [95% CI, 36.7-46.5] to 36.5 [95% CI, 31.7-41.2] per 100,000 infants). Based on the trend, the predicted rate of discharges for intussusception in 2009 was 36.0 (95% CI, 30.2-41.8) per 100,000 infants. The measured rate of hospital discharges for intussusception in 2009 was 33.3 (95% CI, 29.0-37.6) per 100,000 infants.

Conclusion

The reintroduction of rotavirus vaccine since 2006 has not resulted in a detectable increase in the number of hospital discharges for intussusception among US infants.

Project description:BackgroundA three-dose, oral rotavirus vaccine (Rotavac) was introduced in the universal immunization program in India in 2016. A prelicensure trial involving 6799 infants was not large enough to detect a small increased risk of intussusception. Postmarketing surveillance data would be useful in assessing whether the risk of intussusception would be similar to the risk seen with different rotavirus vaccines used in other countries.MethodsWe conducted a multicenter, hospital-based, active surveillance study at 27 hospitals in India. Infants meeting the Brighton level 1 criteria of radiologic or surgical confirmation of intussusception were enrolled, and rotavirus vaccination was ascertained by means of vaccination records. The relative incidence (incidence during the risk window vs. all other times) of intussusception among infants 28 to 365 days of age within risk windows of 1 to 7 days, 8 to 21 days, and 1 to 21 days after vaccination was evaluated by means of a self-controlled case-series analysis. For a subgroup of patients, a matched case-control analysis was performed, with matching for age, sex, and location.ResultsFrom April 2016 through June 2019, a total of 970 infants with intussusception were enrolled, and 589 infants who were 28 to 365 days of age were included in the self-controlled case-series analysis. The relative incidence of intussusception after the first dose was 0.83 (95% confidence interval [CI], 0.00 to 3.00) in the 1-to-7-day risk window and 0.35 (95% CI, 0.00 to 1.09) in the 8-to-21-day risk window. Similar results were observed after the second dose (relative incidence, 0.86 [95% CI, 0.20 to 2.15] and 1.23 [95% CI, 0.60 to 2.10] in the respective risk windows) and after the third dose (relative incidence, 1.65 [95% CI, 0.82 to 2.64] and 1.08 [95% CI, 0.69 to 1.73], respectively). No increase in intussusception risk was found in the case-control analysis.ConclusionsThe rotavirus vaccine produced in India that we evaluated was not associated with intussusception in Indian infants.
