Mistreatment during Childbirth: Impact on Maternal Outcomes and Importance of Provider Perspectives

引用

Open Journal of Obstetrics and Gynecology 2024年第2期14卷 227-233页

作者： Samantha Truong Katherine lindsey Doughty mary Greenwald Annekathryn Goodman Department of Obstetrics and Gynecology Massachusetts General Hospital Harvard Medical School Boston USA

Background: Dying in childbirth is one of the most common causes of death for women. While maternal mortality rates, defined as deaths per 100,000 live births, have been steadily dropping in most countries worldwide, maternal mortality rates have doubled in the United States in the last twenty years. This commentary examines the various contributing factors to this trend. Methods: A literature review was performed using the keywords: maternal mortality, United States, disrespectful maternity care, obstetric violence, provider perspectives, and disparities. Maternal mortality statistics were obtained from the World Health Organization website. Results: Medical factors associated with maternal mortality include increased maternal age and cardiovascular conditions. Social factors include barriers to healthcare access, delays in receiving medical care, reduction in reproductive health services in some states, and non-obstetrical deaths such as accidents, domestic violence, and suicide. Racial inequities and disparities of care are reflected in higher maternal mortality rates for minorities and people of color. Disrespectful maternity care or obstetric violence has been reported worldwide as a factor in delay of lifesaving obstetrical care and reluctance by a pregnant person to access the healthcare system. About one in five US women has reported experiencing mistreatment, varying from verbal abuse to lack of privacy, from coerced procedures to neglect during childbirth. Conclusion: This commentary highlights the importance of inclusion of providers in research on respectful maternity care. Provider burnout, moral distress, limited time, and burden of clinical responsibilities are known challenges to respectful and comprehensive medical care. The association of disrespectful care with poor maternal outcomes needs to be studied. Exploring root causes of disrespectful childbirth care can empower nurses, midwives, and physicians to improve their environment and find solutio

Periodontitis is a chronic inflammatory disease caused by periodontopathic bacteria that affects periodontal support tissues.1 If left untreated,it results in loss of periodontal attachment and alveolar bone *** one-half of adults in the United States older than 30 years have periodontal disease.2 Though the disease is initiated by bacterial infection,it activates host defense systems that eventually lead to the degradation of the *** periodontitis,the disease progress involves further production of pro-inflammatory mediators such as cytokines,proteolytic enzymes like matrix metalloproteinases(MMPs),and their inhibitors.
