Military women's risk factors for and symptoms of genitourinary infections during deployment.

Symptoms of vaginitis and urinary tract infections are miserable, distracting, and significantly affect women's quality of life. Among civilian women, these symptoms account for 10.5 million office visits per year. To examine the scope of the problem for military women during deployment situations, surveys were sent to randomly selected Army and Navy units. Of 841 women who completed the anonymous survey and had been deployed, vaginal infections were experienced by 30.1% and urinary tract infections by 18.4% of them during deployment. Vaginal symptoms were consistent with symptoms associated with the three most common vaginal infections (candida, bacterial, and trichomonas vaginitis). A variety of risk factors, both behavioral and situational, significantly differentiated women with and without infections. Urinary tract infections and vaginal infections are common during deployment situations where resources for self-care and appropriate primary health care for women are scarce or unavailable. One solution is a self-diagnosis and treatment kit for deployed military women.

Effectiveness of nurses as providers of birth labor support in North American hospitals: a randomized controlled trial.

CONTEXT: North American cesarean delivery rates have risen dramatically since the 1960s, without concomitant improvements in perinatal or maternal health. A Cochrane Review concluded that continuous caregiver support during labor has many benefits, including reduced likelihood of cesarean delivery. OBJECTIVE: To evaluate the effectiveness of nurses as providers of labor support in North American hospitals. DESIGN: Randomized controlled trial with prognostic stratification by center and parity. Women were enrolled during a 2-year period (May 1999 to May 2001) and followed up until 6 to 8 postpartum weeks. SETTING: Thirteen US and Canadian hospitals with annual cesarean delivery rates of at least 15%. PARTICIPANTS: A total of 6915 women who had a live singleton fetus or twins, were 34 weeks' gestation or more, and were in established labor at randomization. INTERVENTION: Patients were randomly assigned to receive usual care (n = 3461) or continuous labor support by a specially trained nurse (n = 3454) during labor. MAIN OUTCOME MEASURES: The primary outcome measure was cesarean delivery rate. Other outcomes included intrapartum events and indicators of maternal and neonatal morbidity, both immediately after birth and in the first 6 to 8 postpartum weeks. RESULTS: Data were received for all 6915 women and their infants (n = 6949). The rates of cesarean delivery were almost identical in the 2 groups (12.5% in the continuous labor support group and 12.6% in the usual care group; P =.44). There were no significant differences in other maternal or neonatal events during labor, delivery, or the hospital stay. There were no significant differences in women's perceived control during childbirth or in depression, measured at 6 to 8 postpartum weeks. All comparisons of women's likes and dislikes, and their future preference for amount of nursing support, favored the continuous labor support group. CONCLUSIONS: In hospitals characterized by high rates of routine intrapartum interventions, continuous labor support by nurses does not affect the likelihood of cesarean delivery or other medical or psychosocial outcomes of labor and birth.

The nature of labor pain.

A somewhat paradoxic aspect of childbirth is the association of this physiologic process with acute pain. The experience of pain during labor is the result of complex processing of multiple physiologic and psychosocial factors on a woman's individual interpretation of nociceptive labor stimuli. The nature of labor pain, particularly its physiologic and psychologic influences, is reviewed in the context of a multidimensional framework of the pain experience and an understanding of the origin of labor pain stimuli, of potential adverse effects of the pain response, and of the concepts of suffering and comfort.

Confirming the theoretical structure of the McGill Pain Questionnaire in acute clinical pain.

Based upon a tripartite theoretical model of pain, the Pain Rating Index (PRI) of the McGill Pain Questionnaire (MPQ) continues to be one of the most frequently used instruments to measure clinical pain. Although a number of exploratory factor analytic studies have failed to consistently support the theoretical structure of the instrument, one previous confirmatory factor analytic study of chronic pain did statistically support the a priori model. Because it has been suggested that acute pain may not involve the same dimensions as chronic pain, this study provided a direct test of the theoretical structure of the MPQ through multi-sample confirmatory factor analysis (CFA) using data provided by women experiencing pain during labor (n = 185) and women experiencing acute postoperative pain (n = 192). Results of the LISREL CFA analysis indicated that the a priori, 3-factor, oblique model originally proposed by Melzack provided the most parsimonious representation of the data across the 2 samples of acute pain.

Context and process of informed consent for pharmacologic strategies in labor pain care.

The care of women experiencing labor pain often challenges midwives to provide ethical informed consent for the pharmacologic strategies common in most of America's childbearing environments. A systematic approach to this clinical dilemma begins with a conceptual understanding of the origins of labor pain stimuli, factors affecting their central nervous system processing, and the differentiation of the concepts of pain, suffering, and comfort. These concepts can be integrated into a labor pain care, rather than pain management, model for clinical practice. Because most midwives provide care for laboring women in acute care hospitals, the midwife must also understand how the standards of the Joint Commission on Accreditation of Healthcare Organizations influence the behavior of other professionals in the health care environment for laboring women and the process of informed consent. A systematic approach to informed consent for pharmacologic strategies for labor pain care strategies should begin during pregnancy and includes full, unbiased disclosure of the nature, benefits, risks, side effects, and efficacy of all methods that are available in the chosen birth setting.
