Abstract

Objective:

The purpose of this study was to examine nondelivery, pregnancy-associated hospitalizations in the United States and the factors associated with them.

Study Design:

Population-based nondelivery hospitalizations during pregnancy were obtained from the 1999 and 2000 National Hospital Discharge Survey. Ratios of hospitalizations per 100 deliveries were calculated and analyzed by age, race, and payment source.

Results:

The pregnancy-associated hospitalization ratio for 1999 through 2000 was 12.8 per 100 deliveries (95% CI, 11.8-13.8). Hospitalizations were highest among young women, African American women, and women without private insurance. Preterm labor, nausea and/or vomiting, and genitourinary complications accounted for one half of antenatal hospitalizations.

Conclusion:

Pregnancy-associated hospitalizations declined during the 1990s. This may represent a decline in maternal morbidity or a change in management of pregnancy complications. Future research should be expanded to assess trends in morbidity treated in settings outside of hospitals.

Teratogenicity

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Hospitals-I

Hospitals-I

Hospitals offer medical and surgical care to the sick and injured, along with accommodation while they recover. At the same time, they also provide outpatient, emergency, psychiatric, and rehabilitation services to meet various community needs. In addition to providing medical care, hospitals also act as hubs for medical research and training. Hospitals use clinical procedures and evidence-based practice standards to deliver patient care. To deliver safe and efficient care, a nurse must stay up...

Healthcare Associated Infections II: Preventive Measures

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Hospitals-II

Hospitals-II

Hospitals provide inpatient and outpatient services. Inpatient services provide care to patients that stay in the hospital for an extended period, ranging from days to months. Examples of inpatient services include intensive care units, hospital wards, or surgeries. Outpatient services provide care to patients who come to a hospital for a diagnostic or treatment but do not stay overnight —for example, diagnostic tests, surgical procedures, or health education.
Nurses that work in hospitals have...

Pneumonia I: Introduction

Pneumonia I: Introduction

Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...
