Posttraumatic concerns: a patient-centered approach to outcome assessment after traumatic physical injury.

BACKGROUND: Approximately 2.5 million Americans are admitted to the hospital after traumatic physical injury each year. Few investigations have elicited patients' perspectives regarding posttraumatic outcomes. OBJECTIVE: To identify and categorize physically injured trauma survivors' posttraumatic concerns. RESEARCH DESIGN: Prospective longitudinal investigation; trauma survivors were interviewed during the post-injury hospitalization and again 1, 4, and 12 months after the trauma. SUBJECTS: Ninety-seven, randomly selected, English speaking, hospitalized survivors of motor vehicle-crashes or assaults. MEASURES: At the end of each interview patients were asked, "Of all the things that have happened to you since you were injured, what concerns you the most?" Using an iterative process and working by consensus, investigators categorized patient concerns in content domains. Concern domains were then compared with established measures of posttraumatic stress disorder (PTSD) symptoms and limitations in physical functioning. RESULTS: Seven categories of posttraumatic concerns were identified. During the course of the year, 73% of patients expressed physical health concerns, 58% psychological concerns, 53% work and finance concerns, 40% social concerns, 10% legal concerns, 10% medical concerns, and 20% uncodable concerns. Rater agreement on concern categorization was substantial (kappa = 0.72). The mean number of concerns expressed per patient gradually decreased over time (1 month mean = 1.51; 12 month mean = 1.26) and resembled the trajectories of PTSD symptoms and functional limitations. CONCLUSIONS: The concerns of physically injured trauma survivors are readily elicited and followed up during the course of the year after injury. Open-ended inquiry regarding posttraumatic concerns may complement standardized outcome assessments by identifying and contextualizing the outcomes of greatest importance to patients.

Patients with recognized psychiatric disorders in trauma surgery: incidence, inpatient length of stay, and cost.

BACKGROUND: Although psychiatric disturbances are highly prevalent among traumatically injured inpatients, few investigations have assessed the impact of these disorders on surgical length of stay (LOS) and cost. METHODS: The authors identified all trauma-registry recorded psychiatric diagnoses among patients admitted to University of California Davis Medical Center between January 1993 and December 1996. Linear and logistic regressions were used to assess the unique effects of psychiatric diagnoses on inpatient LOS and cost. RESULTS: A total of 29% of patients had one or more registry-recorded psychiatric diagnosis. Patients with alcohol abuse diagnoses demonstrated 10% to 12% decreases in LOS and cost (p < 0.01), whereas patients with stress disorders, delirium, and psychoses demonstrated 46% to 103% increases in LOS and cost (p < 0.01). CONCLUSION: Patients with recognized psychiatric disorders uniquely impact inpatient trauma surgery LOS and cost. Additional investigations of the processes and outcomes of care could lead to cost-effective performance improvement efforts that target the amelioration of comorbid psychiatric disorders among physically injured trauma survivors.

Chart-recorded psychiatric diagnoses in women giving birth in California in 1992.

OBJECTIVE: Although major advances have been made in the diagnosis and treatment of mental disorders in primary care, few population-based investigations have focused on the obstetrical sector. This study examines the occurrence of chart-recorded psychiatric discharge diagnoses among all women delivering in California hospitals in 1992. METHOD: The authors undertook an archival analysis of the California Health Information for Policy Project data set, which consists of linked hospital discharge and birth certificate data for 580,282 deliveries. Frequencies of ICD-9 psychiatric diagnoses were ascertained. RESULTS: Among all women delivering, 1.5% received psychiatric or substance use diagnoses. Of diagnoses recorded, 75% were substance use disorders, 21% were classified generically as "mental disorder of pregnancy," and other psychiatric disorders accounted for 4%. CONCLUSIONS: The occurrence of psychiatric diagnoses in these women is markedly lower than expected, suggesting an underreporting of psychiatric disorders at delivery. Further investigations into the detection of mental disorders in the obstetrical sector are needed.

Adequacy of prenatal care among women with psychiatric diagnoses giving birth in California in 1994 and 1995.

OBJECTIVE: Although poor prenatal care is detrimental to maternal and infant health, few studies have assessed the adequacy of prenatal care among women with psychiatric diagnoses. This investigation examined the association between chart-recorded psychiatric and substance use diagnoses at the time of delivery and adequacy of prenatal care among all women delivering babies in California hospitals during 1994 and 1995. METHODS: The authors undertook an archival analysis of data from the California Health Information for Policy Project (CHIPP), which consists of linked hospital discharge and birth certificate data for 1,094,178 deliveries in 1994 and 1995. The associations between International Classification of Diseases, 9th Revision, Clinical Modification psychiatric and substance abuse diagnoses and level of prenatal care were examined. Logistic regression analyses were conducted to assess the association between maternal diagnostic category and inadequate prenatal care while controlling for payment source, age, education, race, marital status, and parity (previous births). RESULTS: Women who received psychiatric and substance use diagnoses demonstrated significantly increased risk of inadequate prenatal care compared with women without those diagnoses. CONCLUSIONS: Psychiatric diagnoses were associated with an increased risk of inadequate prenatal care; the association between psychiatric and substance use diagnoses and poor prenatal care persisted even after the analysis controlled for known risk factors. Future investigations will need to elucidate the processes of prenatal care for women with psychiatric disorders so that preventive interventions can be developed.

Sleep disturbances in the Vietnam generation: findings from a nationally representative sample of male Vietnam veterans.

OBJECTIVE: This study analyzed questionnaire items that address complaints about sleep from the National Vietnam Veterans Readjustment Study, a nationally representative sample of the 3.1 million men and women who served in Vietnam. This study compared the frequency of nightmares and difficulties with sleep onset and sleep maintenance in male Vietnam theater veterans with male Vietnam era veteran and male civilian comparison subjects. It focused on the role of combat exposure, nonsleep posttraumatic stress disorder (PTSD) symptoms, comorbid psychiatric and medical disorder, and substance abuse in accounting for different domains of sleep disturbance. METHOD: The authors undertook an archival analysis of the National Vietnam Veterans Readjustment Study database using correlations and linear statistical models. RESULTS: Frequent nightmares were found exclusively in subjects diagnosed with current PTSD at the time of the survey (15.0%). In the sample of veterans who served in Vietnam (N = 1,167), combat exposure was strongly correlated with frequency of nightmares, moderately correlated with sleep onset insomnia, and weakly correlated with disrupted sleep maintenance. A hierarchical multiple regression analysis showed that in Vietnam theater veterans, 57% of the variance in the frequency of nightmares was accounted for by war zone exposure and non-sleep-related PTSD symptoms. Alcohol abuse, chronic medical illnesses, panic disorder, major depression, and mania did not predict the frequency of nightmares after control for nonsleep PTSD symptoms. CONCLUSIONS: Frequent nightmares appear to be virtually specific for PTSD. The nightmare is the domain of sleep disturbance most related to exposure to war zone traumatic stress.

Alternative psychotherapeutic practice among middle class Americans: II: Some conceptual and practical comparisons.

This article will contextualize ethnographic and clinical features that distinguish one particular alternative healing method (Self-Acceptance Training) from 'main-stream' psychotherapeutic procedures. Factors common to many psychotherapies are listed and a series of contrasts and comparisons made by examining definitions of: (1) presenting problems, (2) inciting events, (3) phasic development, (4) taxonomic classifications, (5) therapeutic interventions, and (6) prognostic formulations. The alternative method of treatment described in a companion publication ('SAT') is used to make some specific comparisons (Zatzick and Johnson 1997). Basch's (1980) concise recording of a dynamic therapy is borrowed for purposes of a comparative hypothetical treatment of his patient through a Self-Acceptance Training session. Some directions for future work are suggested.

Alternative psychotherapeutic practice among middle class Americans: I: Case studies and follow-up.

Historically, alternative psychotherapeutic procedures have florished worldwide in various inspirational, spiritualistic and shamanistic versions. However, few investigations have described these interventions in detail, or followed the clinical outcomes longitudinally. This present report is an ethnographic and clinical description of one particular American practitioner's alternative method as it is used with middle class clientele in several regions of the USA. Two case studies are presented in detail while nine individual cases are qualitatively reviewed with one month and one year treatment outcomes reported. A condensed ethnobiographical study of the practitioner's personal and professional life is included.

Posttraumatic stress disorder and functioning and quality of life outcomes in a nationally representative sample of male Vietnam veterans.

OBJECTIVE: Although posttraumatic stress disorder (PTSD) is a highly prevalent and often chronic condition, the relationship between PTSD and functioning and quality of life remains incompletely understood. METHOD: The authors undertook an archival analysis of data from the National Vietnam Veterans Readjustment Study. The study subjects consisted of the nationally representative sample of male Vietnam veterans who participated in the National Vietnam Veterans Readjustment Study. The authors estimated PTSD at the time of the interview with the Mississippi Scale for Combat-Related Posttraumatic Stress Disorder. They examined the following outcomes: diminished well-being, physical limitations, bed day in the past 2 weeks, compromised physical health status, currently not working, and perpetration of violence. Logistic models were used to determine the association between PTSD and outcome; adjustment was made for demographic characteristics and comorbid psychiatric and other medical conditions. RESULTS: The risks of poorer outcome were significantly higher in subjects with PTSD than in subjects without PTSD in five of the six domains. For the outcome domains of physical limitations, not working, compromised physical health, and diminished well-being, these significantly higher risks persisted even in the most conservative logistic models that removed the shared effects of comorbid psychiatric and other medical disorders. CONCLUSIONS: The suffering associated with combat related-PTSD extends beyond the signs and symptoms of the disorder to broader areas of functional and social morbidity. The significantly higher risk of impaired functioning and diminished quality of life uniquely attributable to PTSD suggests that PTSD may well be the core problem in this group of difficult to treat and multiply afflicted patients.

Post-traumatic stress disorder and functioning and quality of life outcomes in female Vietnam veterans.

OBJECTIVE: This investigation assessed whether current post-traumatic stress disorder (PTSD) was associated with impaired functioning in a nationally representative sample of female Vietnam veterans. METHODS: Logistic models were used to determine the association between PTSD and outcome while adjusting for demographic characteristics and medical and psychiatric co-morbidities. RESULTS: PTSD was associated with significantly elevated odds of poorer functioning in five of the six outcome domains; only the association between perpetration of violence in the past year and PTSD did not achieve statistical significance. After adjusting for demographics and medical and psychiatric co-morbidities, PTSD remained associated with significantly elevated odds of bed days, poorer physical health, and currently not working. CONCLUSIONS: Among female Vietnam veterans PTSD is associated with a broad profile of functional impairment. The significantly increased odds of impaired functioning and diminished quality of life suggest that PTSD may be the core problem of the set of problems afflicting female Vietnam veterans.

Does trauma-linked dissociation vary across ethnic groups?

This investigation assessed the relationship between traumatic stress exposure and dissociation in male Vietnam theater veterans from three ethnic groups. Subjects were African-American (N = 61), Caucasian (N = 91), and Hispanic (N = 73) veterans who completed the Dissociative Experience Scale and a measure of war zone stress exposure, and who were rated on the Peritraumatic Dissociative Experiences Questionnaire-Rater Version. Greater exposure to war zone stress was associated with reports of more dissociation at the time of trauma and with more general dissociative experiences both when the data were pooled and when examined separately for each group. After controlling for the effects of war zone stress exposure, the significant differences found in peritraumatic and general dissociative experiences across the three ethnic groups no longer were evident. This investigation demonstrated that among American Vietnam veterans, greater exposure to traumatic stress is related to more dissociative experiences, regardless of ethnicity.

Collaborative interventions for physically injured trauma survivors: a pilot randomized effectiveness trial.

Posttraumatic behavioral and emotional disturbances occur frequently among physically injured hospitalized trauma survivors. This investigation was a pilot randomized effectiveness trial of a 4-month collaborative care intervention for injured motor vehicle crash and assault victims. As surgical inpatients, intervention subjects (N=16) were assigned to a trauma support specialist who provided counseling, consulted with surgical and primary care providers, and attempted postdischarge care coordination. Control subjects (N=18) received usual posttraumatic care. For all participants, posttraumatic stress disorder (PTSD) and depressive symptoms, episodic alcohol intoxication, and functional limitations were evaluated during the hospitalization and 1 and 4 months postinjury. Study logs and field notes revealed that over 75% of intervention activity occurred in the first month after the trauma. One-month post-trauma intervention subjects when compared to controls demonstrated statistically significant decreases in PTSD symptoms as well as a reduction in depressive symptoms. However, at the 4-month assessment, intervention subjects evidenced no significant improvements in PTSD and depressive symptoms, episodic alcohol intoxication, or functional limitations. Future larger scale trials of stepped collaborative care interventions for physically injured trauma survivors are recommended.

Ethical considerations in research participation among acutely injured trauma survivors: an empirical investigation.

Posttraumatic behavioral and emotional disturbances occur frequently among physically injured trauma survivors. Despite increasing investigative interest in the evaluation and treatment of psychological distress in acutely injured patients, few studies have assessed ethical considerations surrounding research participation. The authors empirically investigated ethical considerations in research participation among 117 physically injured, hospitalized, motor vehicle accident and assault survivors. Immediately following a 1-hour research interview, participants responded to 10 questions assessing the experience of research participation. The majority of study subjects found participating in the protocol a positive experience. Most of the hospitalized patients reported that they experienced control over initiation and discontinuation of the protocol and that they derived benefit from their research participation. A minority of participants reported that they experienced unwanted thoughts and unanticipated upset during the protocol and that they felt they could not refuse participation. However, over 95% of patients reported that the benefits of protocol participation outweighed the costs and that in retrospect they would again agree to participate. These results suggest that while a minority of participants may have difficulties with specific aspects of protocol enrollment, overall research participation is well tolerated by the majority of acutely injured, hospitalized, trauma survivors.

Cultural variations in response to painful stimuli.

This review updates the literature on cultural differences in response to laboratory-induced pain. Thirteen studies were located, and there was great diversity among the investigations with regard to racial and ethnic groups studied, methods of pain induction, and experimental outcome. There appear to be no racial/ethnic differences in the ability to discriminate painful stimuli. More difficult to assess is cultural variation in the response to laboratory-induced pain. Age, sex, experimenter ethnicity and the subjects' working conditions may affect and confound the response to painful stimuli. Given these confounds, there is no consistent experimental evidence to suggest cultural differences in pain response. Perspectives derived from the social sciences may help future laboratory researchers better delineate cultural variations in the pain response. The difficulties inherent in the translation of pain descriptors across cultural boundaries make pain tolerance, rather than pain threshold, the more relevant transcultural pain measure. Since tremendous cultural heterogeneity can exist within one racial group and since even ethnic groups within a single racial category demonstrate variations in the response to pain, this field might now profitably focus on the study of ethnic group differences. Delineation of ethnic groups for study will require assessment of variations in intra-ethnic acculturation and assimilation which certainly affect group demarcation and may influence pain behavior. Specific guidelines are presented so that future experimental researchers may better operationalize culture in the laboratory setting.
