创伤后应激障碍与急性应激障碍对比研究

通过对创伤后应激障碍(post-traumatic stress disorder,PTSD)与急性应激障碍(acute stress disorder,ASD)进行比较,研究发现,两者在心理社会因素以及治疗预防等方面十分相似:个体的精神和人格方面影响着ASD与PTSD的发生和发展,对其影响较大的社会因素主要有文化、家庭以及社会支持等;对两者的干预皆为心理治疗和药物治疗相结合,同时要重视社会支持和预防。在发病时间以及病程上两者存在较大差异:ASD发病快、病程短,而PTSD发病慢、病程长。     

Prenatal Stress Exposure and Post-traumatic Stress Disorder Associated With Risk of Postpartum Alcohol Misuse Among Women Veterans

ObjectivesMaternal alcohol misuse during the postpartum period is associated with negative maternal and infant outcomes. This study examined whether greater stress exposure in the year before the baby's birth and maternal post-traumatic stress disorder (PTSD) were associated with postpartum alcohol misuse among a sample of women veterans. Maternal PTSD was also examined as a moderator of the association between stress exposure and postpartum alcohol misuse.MethodsData were drawn from the Center for Maternal and Infant Outcomes Research in Translation study, a multisite prospective cohort study of pregnant and postpartum women veterans. Interviews were conducted within 12 weeks after birth. At this post-birth interview, women reported whether they experienced stressful events (e.g., loss of job, military deployment, separation/divorce) in the year before birth. PTSD diagnosis and postpartum scores on the Alcohol Use Disorders Identification Test (AUDIT-C) were derived from the Department of Veterans Affairs medical records.ResultsModels testing main and interaction effects showed a statistically significant association of both PTSD (p = .02) and stress exposure (p = .04), as well as significant interaction of PTSD and stress exposure (p = .03) with AUDIT-C scores postpartum, after controlling for marital status, age, and race. Specifically, compared with women without PTSD, those with PTSD had higher overall AUDIT-C scores postpartum, regardless of stress exposure. For women without PTSD, more stress exposure before birth was associated with higher AUDIT-C scores during the postpartum phase.ConclusionsPTSD diagnosis and life stressors before infant birth predicted maternal alcohol misuse during the postpartum period. Identifying such risk factors is an initial step in preventing alcohol misuse, with the goal of enhancing postpartum health for the birthing parent and infant.     

Prevalence of Colorectal Cancer Testing and Screening in a Multiethnic Primary Care Population

Colorectal cancer (CRC) screening is strongly supported by evidence and widely recommended, but remains underutilized. This study reports the prevalence of CRC diagnostic testing and CRC screening in three racial/ethnic groups attending the same primary care clinic. A cross-sectional survey was conducted to elicit past history of CRC testing, including test type, indication and timing. A comparable number of African American, Hispanic and non-Hispanic white patients aged 50–80 were recruited. 560 surveys were completed: mean age was 63.4 years, 64% reported minority race/ethnicity, and 96.8% had insurance. Overall, 62.5% [95% CI: 58.5%, 66.5%] of patients were current with any type of CRC test, when diagnostic and screening procedures were included. However, 48.6% [95% CI: 44.5%, 52.7%] of the sample was current with CRC screening, when only procedures performed for screening in asymptomatic patients were included. Patients least likely to be current with testing were those of minority race/ethnicity (48.2% of Hispanics, 56.7% of African Americans and 67.5% of non Hispanic whites, p < 0.05), younger age, (57.6% of those aged 50–64, and 71.4% of those aged 65–80, p < 0.005), and those with private insurance alone (56.0% private, 67.7% public and 68.1% mixed, p < 0.05). Our findings indicate that racial/ethnic and age related disparities in CRC screening exist even in a patient population that has the same source of health care and no differences in insurance status. These results underline the need for providers to emphasize CRC screening in their practices to minority patients and those younger than 65 years of age.     

Measuring Satisfaction Among Low-Income Women: A Prenatal Care Questionnaire

Objective: To evaluate the reliability and construct validity of a prenatal care satisfaction scale. Method: A prenatal care satisfaction scale that included six dimensions of care based on the literature was tested during a telephone interview with 101 first-time African-American and Mexican-American mothers 18 and over who receive Medicaid. Results: The scale exhibited high reliability (Cronbach's alpha = 0.95), as well as good construct validity. The correlation between the scale and rating of the quality of care overall was 0.74 (p < 0.001); the correlation between the scale and whether the women would recommend this provider to a friend was 0.67 (p < 0.001). Results from correlation and factor analysis suggested a different set of dimensions than those described in the literature. Conclusion: The 22-question satisfaction with prenatal care scale has excellent reliability and construct validity and taps six established dimensions of satisfaction, including the art of care, technical quality, access, physical environment, availability, and efficacy. The multidimensional scale allows for alternative groupings of the domains of satisfaction as our understanding of prenatal care satisfaction increases.     

Post-traumatic Stress Disorder (PTSD): A Webliography

Post-traumatic stress disorder (PTSD) is a psychiatric condition that can result from experiencing or living through traumatic events. This can include medical events, such as a heart attack or surgery, or witnessing a life-threatening event, such as combat, a natural disaster, a car accident, terroristic events, domestic violence, early childhood trauma, or sexual assault. The U.S. Department of Veterans Affairs reports about 60% of all men and 50% of all women will experience trauma at some point in their lives. It is estimated 7–8% of the population will additionally experience PTSD. Identifying symptoms and managing treatment is an imperative aspect for recovery. In addition to formal treatment, there are a variety of resources available for survivors of PTSD which extend beyond hospital walls. This article will describe post-traumatic stress disorder and present online resources, mobile applications, and peer support groups for the assistance of survivors’ recovery.     

Posttraumatic Stress Disorder Among Women Receiving Prenatal Care at Three Federally Qualified Health Care Centers

This study assessed the prevalence and interrelationships of posttraumatic stress disorder (PTSD), antecedent trauma, and psychosocial risk factors among pregnant women served at three urban Federally Qualified Health Care Centers. This analysis was part of a validation study of the prenatal risk overview, a structured psychosocial risk screening interview. The study sample included 745 prenatal patients at three clinics who also were administered the major depression, PTSD, alcohol, and drug use modules of the Structured Clinical Interview for DSM-IV (SCID). Most participants were women of color (89.1 %), under the age of 25 years (67.8 %), and unmarried (86.2 %). The rate for a current PTSD diagnosis was 6.6 % and for subthreshold PTSD 4.2 %. More than half (54 %) of participants reported a trauma that met PTSD criteria; 21 % reported being a victim of or witness to violence or abuse, including 78 % of women with PTSD. Compared to those without PTSD, those with PTSD were 4 times more likely to be at risk for housing instability (AOR 4.15; 95 %CI 1.76, 9.80) and depression (AOR3.91; 95 %CI 2.05, 7.47) and 2 times as likely to be at risk for a drug use disorder (AOR 1.96, 95 %CI 1.04, 3.71) and involvement with child protective services (AOR 2.27; 95 % CI 1.06, 4.89). Women age 25 or older were twice as likely to meet PTSD diagnostic criteria as younger women (AOR2.27; 95 %CI 1.21, 4.28). Trauma exposure and pervasive PTSD were common in this population. Systematic psychosocial risk screening may identify the population with PTSD even without questions specific to this disorder.     

The Influence of Site of Care on the Content of Prenatal Care for Low-Income Women

Objective: To assess whether site of prenatal care influences the content of prenatal care for low-income women. Design: Bivariate and logistic analyses of prenatal care content for low-income women provided at five different types of care sites (private offices, HMOs, publicly funded clinics, hospital clinics, and other sites of care), controlling for sociodemographic, behavioral, and maternal health characteristics. Participants: A sample of 3405 low-income women selected from a nationally representative sample of 9953 women surveyed by the National Maternal and Infant Health Survey, who had singleton live births in 1988, had some prenatal care (PNC), Medicaid participation, or a family income less than $12,000/year. Outcome Measures: Maternal report of seven initial PNC procedures (individually and combined), six areas of PNC advice (individually and combined), and participation in the Women Infant Children (WIC) nutrition program. Results: The content of PNC provided for low-income women does not meet the recommendations of the U.S. Public Health Service, and varies by site of delivery. Low-income women in publicly funded clinics (health departments and community health centers) report receiving more total initial PNC procedures and total PNC advice and have greater participation in the WIC program than similar women receiving PNC in private offices. Conclusions: Publicly funded sites of care appear to provide more comprehensive prenatal care services than private office settings. Health care systems reforms which assume equality of care across all sites, or which limit services to restricted sites, may foster unequal access to comprehensive PNC.     

Screening for Psychosocial Risk in an Urban Prenatal Clinic Population

SUMMARY

Recognition of the need for early identification of risk factors led a “practice-based research” (Epstein, 1995) team of social workers in the prenatal clinic at Mount Sinai to develop a standardized, comprehensive screening, monitoring and evaluation instrument for all patients in their service. To explore the effects of psychosocial risk factors empirically, available information collected from 435 women screened with the original instrument between 1992-93 was converted into a quantitative data-base. The intention was to conduct a retrospective study of the prenatal patient population, including demographic characteristics, problems presented, social work interventions, and treatment outcomes. Among the findings anxiety and ambivalence related to pregnancy were significant risk factors. This model of social work service delivery is consistent with the focus of prenatal care as clinical preventative medicine.     

Extending Delivery Coverage to Include Prenatal Care for Low-Income,Immigrant Women Is a Cost-Effective Strategy

ObjectiveTo compare the outcomes and cost effectiveness of two alternate policy strategies for prenatal care among low-income, immigrant women: coverage for delivery only (the federal standard) and prenatal care with delivery coverage (state option under the Children's Health Insurance Program).MethodsA decision-analytic model was developed to determine the cost effectiveness of two alternate policies for pregnancy coverage. All states currently provide coverage for delivery, and 19 states also provide coverage for prenatal care. An estimated 84,000 unauthorized immigrant women have pregnancies where no prenatal care is covered. Our outcomes were costs, quality-adjusted life-years, and cases of cerebral palsy and infant death before age 1. Model inputs were obtained from a database of Oregon Medicaid claims and the literature. Univariate and bivariate sensitivity analyses, as well as a Monte Carlo simulation, were performed.ResultsExtending prenatal coverage is a cost-effective strategy. Providing prenatal care for the 84,000 women annually who are currently uninsured could prevent 117 infant deaths and 34 cases of cerebral palsy. Prenatal care coverage costs $380 more per woman than covering the delivery only. For every 865 additional women receiving prenatal care, one infant death would be averted, at an average cost of $328,700. Cost-effectiveness acceptability curve analyses suggest a 99% probability that providing prenatal care is more cost effective at a willingness-to-pay threshold of $100,000 per quality-adjusted life-year.ConclusionsExtending prenatal care to low-income, immigrant women, regardless of citizenship status, is a cost-effective strategy.     

Posttraumatic Stress Disorder in Rural Primary Care: Improving Care for Mental Health Following Bioterrorism

CONTEXT: Recent bioterrorism attacks have highlighted the critical need for health care organizations to prepare for future threats. Yet, relatively little attention has been paid to the mental health needs of rural communities in the wake of such events. A critical aspect of bioterrorism is emphasis on generating fear and uncertainty, thereby contributing to increased needs for mental health care, particularly for posttraumatic stress disorder, which has been estimated to occur in 28% of terrorism survivors. PURPOSE: Prior experience with natural disasters suggests that first responders typically focus on immediate medical trauma or injury, leaving rural communities to struggle with the burden of unmet mental health needs both in the immediate aftermath and over the longer term. The purpose of the present article is to draw attention to the greater need to educate rural primary care providers who will be the frontline providers of mental health services following bioterrorism, given the limited availability of tertiary mental health care in rural communities. METHODS: We reviewed the literature related to bioterrorism events and mental health with an emphasis on rural communities. FINDINGS AND CONCLUSIONS: Public health agencies should work with rural primary care providers and mental health professionals to develop educational interventions focused on posttraumatic stress disorder and other mental disorders, as well as algorithms for assessment, referral, and treatment of post-event psychological disorders and somatic complaints to ensure the availability, continuity, and delivery of quality mental health care for rural residents following bioterrorism and other public health emergencies.     

Self-Reported Barriers to Colorectal Cancer Screening in a Racially Diverse, Low-Income Study Population

Colorectal cancer (CRC) screening is underutilized, especially in low income, high minority populations. We examined the effect test-specific barriers have on colonoscopy and fecal immunochemical test (FIT) completion, what rationales are given for non-completion, and what “switch” patterns exist when participants are allowed to switch from one test to another. Low income adults who were not up-to-date with CRC screening guidelines were recruited from safety-net clinics and offered colonoscopy or FIT (n = 418). Follow up telephone surveys assessed test-specific barriers. Test completion was determined from patient medical records. For subjects who desired colonoscopy at baseline, finding a time to come in and transportation applied more to non-completers than completers (p = 0.001 and p < 0.001, respectively). For participants who initially wanted FIT, keeping track of cards, never putting stool on cards, and not remembering to mail cards back applied more to non-completers than completers (p = 0.003, p = 0.006, and p < 0.001, respectively). The most common rationale given for not completing screening was a desire for the other screening modality: 7 % of patients who initially preferred screening by FIT completed colonoscopy, while 8 % of patients who initially preferred screening by colonoscopy completed FIT. We conclude that test-specific barriers apply more to subjects who did not complete CRC screening. As a common rationale for test non-completion is a desire to receive a different screening modality, our findings suggest screening rates could be increased by giving patients the opportunity to switch tests after an initial choice is made.     

Discrepancy in Diagnosis and Treatment of Post-traumatic Stress Disorder (PTSD): Treatment for the Wrong Reason

In primary care (PC), patients with post-traumatic stress disorder (PTSD) are often undiagnosed. To determine variables associated with treatment, this cross-sectional study assessed 592 adult patients for PTSD. Electronic medical record (EMR) review of the prior 12 months assessed mental health (MH) diagnoses and MH treatments [selective serotonin reuptake inhibitor (SSRI) and/or ≥1 visit with MH professional]. Of 133 adults with PTSD, half (49%; 66/133) received an SSRI (18%), a visit with MH professional (14%), or both (17%). Of those treated, 88% (58/66) had an EMR MH diagnosis, the majority (71%; 47/66) depression and (18%; 12/66) PTSD. The odds of receiving MH treatment were increased 8.2 times (95% CI 3.1–21.5) for patients with an EMR MH diagnosis. Nearly 50% of patients with PTSD received MH treatment, yet few had this diagnosis documented. Treatment was likely due to overlap in the management of PTSD and other mental illnesses.     

Screening for Posttraumatic Stress Disorder among Somali ex-combatants: A validation study

Background  

In Somalia, a large number of active and former combatants are affected by psychological problems such as Posttraumatic Stress Disorder (PTSD). This disorder impairs their ability to re-integrate into civilian life. However, many screening instruments for Posttraumatic Stress Disorder used in post-conflict settings have limited validity. Here we report on development and validation of a screening tool for PTSD in Somali language with a sample of ex-combatants.     

Initiation of and Barriers to Prenatal Care Use Among Low-Income Women in San Antonio,Texas

Healthy People 2010 goals set a target of 90% of mothers starting prenatal care in the first trimester of pregnancy. While there are questions about the value of prenatal care (PNC), there is much observational evidence of the benefits of PNC including reduction in maternal, fetal, perinatal, and infant deaths. The objective of this study was to understand barriers to PNC as well as factors that impact early initiation of care among low-income women in San Antonio, Texas. A survey study was conducted among low-income women seeking care at selected public health clinics in San Antonio. Interviews were conducted with 444 women. Study results show that women with social barriers, those who were less educated, who were living alone (i.e. without an adult partner or spouse), or who had not planned their pregnancies were more likely to initiate PNC late in their pregnancies. It was also observed that women who enrolled in the WIC program were more likely to initiate PNC early in their pregnancies. Women who initiated PNC late in pregnancy had the highest odds of reporting service-related barriers to receiving care. However, financial and personal barriers created no significant obstacles to women initiating PNC. The majority of women in this study reported that they were aware of the importance of PNC, knew where to go for care during pregnancy, and were able to pay for care through financial assistance, yet some did not initiate early prenatal care. This clearly establishes that the decision making process regarding PNC is complex. It is important that programs consider the complexity of the decision-making process and the priorities women set during pregnancy in planning interventions, particularly those that target low-income women. This could increase the likelihood that these women will seek PNC early in their pregnancies.     

Psychotherapy Utilization,Preferences, and Retention among Women Veterans with Post-traumatic Stress Disorder

BackgroundPsychotherapy is the gold standard treatment for post-traumatic stress disorder (PTSD), yet psychotherapy use and retention among veterans is low. Little is known about the barriers to care and factors associated with women veterans' PTSD psychotherapy use and retention. Using a nationally representative sample of 986 women Veterans Health Administration primary care users with PTSD and a perceived need for mental health care, we examined 1) the proportion of women who used psychotherapy, 2) retention in psychotherapy among women who used any psychotherapy, and 3) individual factors related to psychotherapy use and retention.MethodsWomen completed a survey on their mental health care experiences. Outpatient mental health care use in the year before the survey was obtained from Veterans Health Administration administrative data.ResultsMost women (79.1%) used psychotherapy, and 41.7% of those women had a minimal therapeutic dose of psychotherapy (≥8 visits). Mental health diagnostic comorbidity and being African American/Black or identifying as neither African American/Black nor White were significantly associated with higher psychotherapy use. Mental health diagnostic comorbidity, exposure to military sexual trauma, and receiving treatment aligned with gender-related and group-related preferences were associated with higher psychotherapy retention. Being a parent was associated with lower retention.ConclusionsAlthough a significant proportion of women veterans with PTSD are using psychotherapy, retention is enhanced when women are able to obtain treatment aligned with their preferences. Thus, efforts to promote patient-centered, shared decisions regarding mental health treatment options could increase the efficacy and efficiency of treatment for PTSD among women.
