Depression screening attitudes and practices among obstetrician-gynecologists

OBJECTIVE

To assess obstetrician-gynecologists' attitudes and practices related to depression screening.

METHOD

A total of 282 obstetrician-gynecologists completed a 36-question mail survey that assessed attitudes regarding depression screening, training to treat depression, psychosocial concern, professional influence, and ease of screening.

RESULT

Depression screening (employed regardless of signs or symptoms) was reported by 44% of physicians. Positive attitudes toward depression screening, high psychosocial concern, high ease of screening, and adequate training to treat depression were significant independent predictors of depression screening practices.

CONCLUSION

The majority of obstetrician-gynecologists are concerned about depression, believe depression screening is effective, and perform some degree of depression screening with their patients. However, they perceive depression screening as difficult to carry out in everyday practice, and some question whether screening improves outcomes.

Health care costs associated with posttraumatic stress disorder symptoms in women

BACKGROUND

Posttraumatic stress disorder (PTSD) is a prevalent disorder that has been associated with elevated rates of medically unexplained physical symptoms, significant functional impairment, and high health care use. However, little is known about actual health care costs associated with PTSD.

METHODS

We administered the PTSD Checklist (PCL) to 1225 female members of a metropolitan health maintenance organization and validated the instrument using a structured PTSD interview in a subset of 268 women. Participants were classified into 3 groups by PCL score: low (<30), moderate (30-44), and high (> or =45). By using the cost accounting system of the health maintenance organization, we examined differences between the groups with respect to total and component health care costs, controlling for chronic medical illness and other forms of psychological distress.

RESULTS

The total unadjusted mean +/- SD annual health care costs were 3060 US dollars +/- 6381 US dollars (median, 1283 US dollars) for the high PCL score group, 1779 US dollars +/- 3008 US dollars (median, 829 US dollars) for the moderate PCL score group, and 1646 US dollars +/- 5156 US dollars (median, 609 US dollars) for the low PCL score group. After adjusting for depression, chronic medical disease, and demographic factors, women with high PCL scores had a significantly greater odds of having nonzero health care costs compared with women with low PCL scores (odds ratio, 13.14; 95% confidence interval, 1.70-101.19). Compared with women in the low PCL score group, those in the moderate PCL score group had, on average, a 38% increase in adjusted total annual median costs, and those in the high PCL score group had a 104% increase.

CONCLUSIONS

Women with PTSD symptoms in this study had significantly higher total and component health care costs, even after controlling for depression, chronic medical illness, and demographic differences. These findings are similar to those found in studies of costs related to major depression and suggest that instituting health services interventions to improve recognition and treatment of PTSD in primary and specialty care clinics may be a cost-effective approach for lowering the prevalence of this disorder.

Depression treatment in a sample of 1,801 depressed older adults in primary care

OBJECTIVES

To examine rates and predictors of lifetime and recent depression treatment in a sample of 1,801 depressed older primary care patients

DESIGN

Cross sectional survey data collected from 1999 to 2001 as part of a treatment effectiveness trial.

SETTING

Eighteen primary care clinics belonging to eight organizations in five states.

PARTICIPANTS

One thousand eight hundred one clinic users aged 60 and older who met diagnostic criteria for major depression or dysthymia.

MEASUREMENTS

Lifetime depression treatment was defined as ever having received a prescription medication, counseling, or psychotherapy for depression. Potentially effective recent depression treatment was defined as 2 or more months of antidepressant medications or four or more sessions of counseling or psychotherapy for depression in the past 3 months.

RESULTS

The mean age +/- standard deviation was 71.2 +/- 7.5; 65% of subjects were women. Twenty-three percent of the sample came from ethnic minority groups (12% were African American, 8% were Latino, and 3% belonged to other ethnic minorities). The median household income was $23,000. Most study participants (83%) reported depressive symptoms for 2 or more years, and most (71%) reported two or more prior depressive episodes. About 65% reported any lifetime depression treatment, and 46% reported some depression treatment in the past 3 months, although only 29% reported potentially effective recent depression treatment. Most of the treatment provided consisted of antidepressant medications, with newer antidepressants such as selective serotonin reuptake inhibitors constituting the majority (78%) of antidepressants used. Most participants indicated a preference for counseling or psychotherapy over antidepressant medications, but only 8% had received such treatment in the past 3 months, and only 1% reported four or more sessions of counseling. Men, African Americans, Latinos, those without two or more prior episodes of depression, and those who preferred counseling to antidepressant medications reported significantly lower rates of depression care.

CONCLUSION

The findings suggest that there is considerable opportunity to improve care for older adults with depression. Particular efforts should be focused on improving access to depression care for older men, African Americans, Latinos, and patients who prefer treatments other than antidepressants.

Moving treatment research from clinical trials to the real world

Recently the National Institutes of Health has been emphasizing research that takes findings generated by clinical research and translates them into treatments for patients who are seen in day-to-day nonresearch settings. This translational process requires a series of steps in which elements of both efficacy and effectiveness research are combined into successively more complex designs. However, there has been little discussion of exactly how to develop and operationalize these designs. This article describes an approach to the development of these hybrid designs. Their operationalization is illustrated by using the design of an ongoing effectiveness treatment study of panic disorder in primary care. Experts in both efficacy and effectiveness research collaborated to address the methodologic and data collection issues that need to be considered in designing a first-generation effectiveness study. Elements of the overall study design, setting or service delivery context, inclusion and exclusion criteria, recruitment and screening, assessment tools, and intervention modification are discussed to illustrate the thinking behind and rationale for decisions about these different design components. Although the series of decisions for this study were partly influenced by considerations specific to the diagnosis of panic disorder and the context of the primary care setting, the general stepwise approach to designing treatment interventions using an effectiveness model is relevant for the development of similar designs for other mental disorders and other settings.

Managed care, access to specialists, and outcomes among primary care patients with pain

OBJECTIVE

To determine whether managed care controls were associated with reduced access to specialists and worse outcomes among primary care patients with pain.

DATA SOURCES/STUDY SETTING

Patient, physician, and office manager questionnaires collected in the Seattle area in 1996-1997, plus data abstracted from patient records and health plans.

STUDY DESIGN

A prospective cohort study of 2,275 adult patients with common pain problems recruited in the offices of 261 primary care physicians in Seattle.

DATA COLLECTION

Patients completed a waiting room questionnaire and follow-up surveys at the end of the first and sixth months to measure access to specialists and outcomes. Intensity of managed care controls measured by plan managed care index and benefit/cost-sharing indexes, office managed care index, physician compensation, financial incentives, and use of clinical guidelines.

PRINCIPAL FINDINGS

A financial withhold for referral was associated with a lower likelihood of referral to a physician specialist, a greater likelihood of seeing a specialist without referral, and a lower patient rating of care from the primary physician. Otherwise, patients in more managed offices and with greater out-of-network plan benefits had greater access to specialists. Patients with more versus less managed care had similar health outcomes, but patients in more managed offices had lower ratings of care provided by their primary physicians.

CONCLUSIONS

Increased managed care controls were generally not associated with reduced access to specialists and worse health outcomes for primary care patients with pain, but patients in more managed offices had lower ratings of care provided by their primary physicians.

Effectiveness of collaborative care depression treatment in Veterans' Affairs primary care

OBJECTIVE

To compare collaborative care for treatment of depression in primary care with consult-liaison (CL) care. In collaborative care, a mental health team provided a treatment plan to the primary care provider, telephoned patients to support adherence to the plan, reviewed treatment results, and suggested modifications to the provider. In CL care, study clinicians informed the primary care provider of the diagnosis and facilitated referrals to psychiatry residents practicing in the primary care clinic.

DESIGN

Patients were randomly assigned to treatment model by clinic firm.

SETTING

VA primary care clinic.

PARTICIPANTS

One hundred sixty-eight collaborative care and 186 CL patients who met criteria for major depression and/or dysthymia.

MEASUREMENTS

Hopkins Symptom Checklist (SCL-20), Short Form (SF)-36, Sheehan Disability Scale.

MAIN RESULTS

Collaborative care produced greater improvement than CL in depressive symptomatology from baseline to 3 months (SCL-20 change scores), but at 9 months there was no significant difference. The intervention increased the proportion of patients receiving prescriptions and cognitive behavioral therapy. Collaborative care produced significantly greater improvement on the Sheehan at 3 months. A greater proportion of collaborative care patients exhibited an improvement in SF-36 Mental Component Score of 5 points or more from baseline to 9 months.

CONCLUSIONS

Collaborative care resulted in more rapid improvement in depression symptomatology, and a more rapid and sustained improvement in mental health status compared to the more standard model. Mounting evidence indicates that collaboration between primary care providers and mental health specialists can improve depression treatment and supports the necessary changes in clinic structure and incentives.

Impacting late life depression: integrating a depression intervention into primary care

groups and semi-structured individual interviews with all Depression Clinical Specialists (DCSs) working with Project IMPACT (Improving Mood: Promoting Access to Collaborative Treatment), a study testing a collaborative care intervention for late life depression, to examine integration of the intervention model into primary care. DCSs described key intervention components, including supervision from a psychiatrist and a liaison primary care provider, weekly team meetings, computerized patient tracking, and outcomes assessment tools as effective in supporting patient care. DCSs discussed details of protocols, training, environmental set-up, and interpersonal factors that seemed to facilitate integration. DCSs also identified research-related factors that may need to be preserved in the real world. Basic elements of the IMPACT model seem to support integration of late life depression care into primary care. Research-related components may need modification for dissemination.

Collaborative care management of late-life depression in the primary care setting: a randomized controlled trial

CONTEXT

Few depressed older adults receive effective treatment in primary care settings.

OBJECTIVE

To determine the effectiveness of the Improving Mood-Promoting Access to Collaborative Treatment (IMPACT) collaborative care management program for late-life depression.

DESIGN

Randomized controlled trial with recruitment from July 1999 to August 2001.

SETTING

Eighteen primary care clinics from 8 health care organizations in 5 states.

PARTICIPANTS

A total of 1801 patients aged 60 years or older with major depression (17%), dysthymic disorder (30%), or both (53%).

INTERVENTION

Patients were randomly assigned to the IMPACT intervention (n = 906) or to usual care (n = 895). Intervention patients had access for up to 12 months to a depression care manager who was supervised by a psychiatrist and a primary care expert and who offered education, care management, and support of antidepressant management by the patient's primary care physician or a brief psychotherapy for depression, Problem Solving Treatment in Primary Care.

MAIN OUTCOME MEASURES

Assessments at baseline and at 3, 6, and 12 months for depression, depression treatments, satisfaction with care, functional impairment, and quality of life.

RESULTS

At 12 months, 45% of intervention patients had a 50% or greater reduction in depressive symptoms from baseline compared with 19% of usual care participants (odds ratio [OR], 3.45; 95% confidence interval [CI], 2.71-4.38; P<.001). Intervention patients also experienced greater rates of depression treatment (OR, 2.98; 95% CI, 2.34-3.79; P<.001), more satisfaction with depression care (OR, 3.38; 95% CI, 2.66-4.30; P<.001), lower depression severity (range, 0-4; between-group difference, -0.4; 95% CI, -0.46 to -0.33; P<.001), less functional impairment (range, 0-10; between-group difference, -0.91; 95% CI, -1.19 to -0.64; P<.001), and greater quality of life (range, 0-10; between-group difference, 0.56; 95% CI, 0.32-0.79; P<.001) than participants assigned to the usual care group.

CONCLUSION

The IMPACT collaborative care model appears to be feasible and significantly more effective than usual care for depression in a wide range of primary care practices.

Undertreatment of panic disorder in primary care: role of patient and physician characteristics

BACKGROUND

In contrast with many studies describing the usual care for major depression in the primary care setting, there are few data on treatment received by primary care patients with panic disorder.

METHODS

This prospective cohort study describes the self-reported medication use, at 3-month intervals for 1 year, of 58 patients with panic disorder and predictors of the use of appropriate (type, dose, and duration) medication.

RESULTS

Approximately one half the patients received some type of antipanic medication at each interval, with selective serotonin reuptake inhibitors (SSRIs) the most common. Pharmacy records indicate that about 40% of patients not taking medication had received an initial physician prescription. Adequacy of dose and duration was achieved in only two thirds of the medication trials, usually with an SSRI. Patient characteristics (agoraphobia and low neuroticism) but not physician characteristics (eg, specialty, level of training, or years in practice) predicted those patients who had an adequate trial during at least one time interval. The relation between adequacy of medication and outcome was minimal.

CONCLUSION

These findings highlight the continued undertreatment of panic disorder in primary care but suggest that focused efforts at physician education about diagnosis and treatment are less likely to increase rates of treatment compared with efforts to educate patients and improve the care process with more frequent visits and monitoring.

Validation of the PTSD checklist in an HMO sample of women

Although Post-traumatic Stress Disorder (PTSD) is common among patients seeking care at medical clinics, little is known about the performance of screening instruments for this disorder in these settings. Previous studies of acute trauma populations using the PTSD Checklist (PCL) have suggested that scores of 45-50 provide the best discrimination between cases and noncases. We gave the PCL to 1,225 randomly selected women enrolled in an HMO. After interviewing a sample of 261 of these women using a structured, clinician-administered PTSD interview, we compared the results of the PCL to the clinician interviews over a range of possible cut scores using Receiver Operating Characteristic analysis. The optimum balance of sensitivity and specificity for this population was a score of 30, yielding a sensitivity of.82 and specificity of.76. The positive and negative likelihood ratios for this cut score were 3.40 and 0.24, respectively. By comparison, the use of 45 as a cut score would result in very low sensitivity (.36) in this setting. The lower cut score found in this study may indicate that the use of previously published cut scores of 45-50 may not optimize the function of the PCL as a screening tool outside of acute trauma settings due to an unacceptably high number of false negative cases.

Long-term effects of a collaborative care intervention in persistently depressed primary care patients

OBJECTIVE

A previous study described the effect of a collaborative care intervention on improving adherence to antidepressant medications and depressive and functional outcomes of patients with persistent depressive symptoms 8 weeks after the primary care physician initiated treatment. This paper examined the 28-month effect of this intervention on adherence, depressive symptoms, functioning, and health care costs.

DESIGN

Randomized trial of stepped collaborative care intervention versus usual care.

SETTING

HMO in Seattle, Wash.

PATIENTS

Patients with major depression were stratified into severe and moderate depression groups prior to randomization.

INTERVENTIONS

A multifaceted intervention targeting patient, physician, and process of care, using collaborative management by a psychiatrist and a primary care physician.

MEASURES AND MAIN RESULTS

The collaborative care intervention was associated with continued improvement in depressive symptoms at 28 months in patients in the moderate-severity group (F1,87 = 8.65; P =.004), but not in patients in the high-severity group (F1,51 = 0.02; P =.88) Improvements in the intervention group in antidepressant adherence were found to occur for the first 6 months (chi2(1) = 8.23; P <.01) and second 6-month period (chi2(1) = 5.98; P <.05) after randomization in the high-severity group and for 6 months after randomization in the moderate-severity group(chi2(1) = 6.10; P <.05). There were no significant differences in total ambulatory costs between intervention and control patients over the 28-month period (F1,180 = 0.77; P =.40).

CONCLUSIONS

A collaborative care intervention was associated with sustained improvement in depressive outcomes without additional health care costs in approximately two thirds of primary care patients with persistent depressive symptoms.

Methodological issues in the recruitment of primary care patients with depression

OBJECTIVE

To compare two strategies of patient recruitment, waiting room (WR) screening and screening after physician referral (PR), for participation in a treatment-outcome study of minor depression and dysthymia in primary care. The influence of demographic factors on patients' refusal to participate in WR screening was also examined.

METHOD

Of a convenience sample of 3,344 first stage patients, a total of 609 patients were evaluated in a semi-structured manner using a two-stage screening procedure from the mood module of the Primary Care Evaluation of Mental Disorders (PRIME-MD).

RESULTS

Male and older patients were more likely to refuse participation in screening than female and younger patients. Waiting room screens yielded a higher number of qualified patients compared to PR screens, but PR screens yielded a higher percentage of patients who qualified for further participation.

CONCLUSIONS

The recruitment of male and older primary care patients is complicated by their tendency to refuse participation in WR screening for a treatment-outcome study of milder depression. Although each recruitment strategy offers advantages and disadvantages, the simultaneous use of both is recommended to recruit the most patients in the least amount of time.

Psychiatric and substance use disorders as risk factors for low birth weight and preterm delivery

OBJECTIVE

We examined the associations between psychiatric and substance use diagnoses and low birth weight (LBW), very low birth weight (VLBW), and preterm delivery among all women delivering in California hospitals during 1995.

METHODS

This population-based retrospective cohort analysis used linked hospital discharge and birth certificate data for 521,490 deliveries. Logistic regression analyses were conducted to assess the associations between maternal psychiatric and substance use hospital discharge diagnoses and LBW, VLBW, and preterm delivery while controlling for maternal demographic and medical characteristics.

RESULTS

Women with psychiatric diagnoses had a significantly higher risk of LBW (adjusted odds ratio [OR] 2.0; 95% confidence interval [CI] 1.7, 2.3), VLBW (OR 2.9; 95% CI 2.1, 3.9), and preterm delivery (OR 1.6; 95% CI 1.4, 1.9) compared with women without those diagnoses. Substance use diagnoses were also associated with higher risk of LBW (OR 3.7; 95% CI 3.4, 4.0), VLBW (OR 2.8; 95% CI 2.3, 3.3), and preterm delivery (OR 2.4; 95% CI 2.3, 2.6).

CONCLUSION

Maternal psychiatric and substance use diagnoses were independently associated with low birth weight and preterm delivery in the population of women delivering in California in 1995. Identifying pregnant women with current psychiatric disorders and increased monitoring for preterm and low birth weight delivery among this population may be indicated.

Prevalence of comorbid psychiatric illness and its impact on symptom perception, quality of life, and functional status in women with urinary incontinence

OBJECTIVE

The purpose of this study was to determine the prevalence and impact of major depression and panic disorder in women with urinary incontinence.

STUDY DESIGN

Participants were 218 consecutive women with urinary incontinence over a 14-month period. Major depression and panic disorder diagnoses, symptom perception, incontinence-specific quality of life, functional status, and urinary incontinence type were assessed.

RESULTS

The overall prevalence of major depression and panic disorder was 16% and 7%, respectively. In a comparison to patients with stress urinary incontinence, the odds of having major depression were 9.2 for patients with urge and 13.5 for patients with mixed urinary incontinence. Although clinically similar to patients who did not have depression, patients with depression rated their urinary incontinence as significantly more severe and had greater quality of life and functional status impairment.

CONCLUSION

Current major depression and panic disorder are highly prevalent in women with urinary incontinence. Patients with urge and mixed urinary incontinence are significantly more likely to have coexistent psychiatric illness. Comorbid major depression significantly impacts a patient's urinary incontinence symptom reporting, incontinence-specific quality of life, and functional status.

Response styles among patients with minor depression and dysthymia in primary care

Ruminative responses to depression have predicted duration and severity of depressive symptoms. The authors examined how response styles change over the course of treatment for depression and as a function of type of treatment. They also examined the ability of response styles to predict treatment outcome and status at follow-up. Primary care patients (n = 96) with dysthymia or minor depression were randomly assigned to problem-solving therapy, paroxetine, or placebo. Patients' depressive symptoms and rumination, but not distraction, decreased over time. Pretreatment rumination and distraction were associated with more depressive symptoms at the conclusion of treatment; the latter finding was not consistent with the response style theory of depression. Results are discussed in terms of their implications for this theory.

Predicting posttraumatic distress in hospitalized trauma survivors with acute injuries

OBJECTIVE

Each year approximately 2.5 million Americans are hospitalized after sustaining traumatic physical injuries. Few investigations have comprehensively screened for posttraumatic symptomatic distress or identified predictors of posttraumatic stress disorder (PTSD) in representative samples of surgical inpatients.

METHOD

The subjects were 101 randomly selected survivors of motor vehicle crashes or assaults who were interviewed while hospitalized and 1, 4, and 12 months after injury. In the surgical ward, inpatients were screened for PTSD, depressive, and dissociative symptoms, for prior trauma, for pre-event functioning, and for alcohol and drug intoxication. Patient demographic and injury characteristics were also recorded. Random coefficient regression models were used to assess the association between these clinical, injury, and demographic characteristics and PTSD symptom levels over the year after the injury.

RESULTS

Of the 101 surgical inpatients, 73% screened positive for high levels of symptomatic distress and/or substance intoxication. At 1, 4, and 12 months after the injury, 30%-40% reported symptoms consistent with a diagnosis of PTSD. High ward PTSD symptom levels were the strongest and most parsimonious predictor of persistent symptoms over the course of the year. Greater prior trauma, stimulant intoxication, and female gender were also associated with higher symptom levels. Increasing injury severity, however, was not associated with higher PTSD symptom levels.

CONCLUSIONS

Clinical and demographic characteristics readily identifiable at the time of surgical inpatient hospitalization predict PTSD symptoms over the year after injury. Effectiveness trials that test screening and intervention procedures for at-risk inpatients should be developed.

Response styles among patients with minor depression and dysthymia in primary care

Ruminative responses to depression have predicted duration and severity of depressive symptoms. The authors examined how response styles change over the course of treatment for depression and as a function of type of treatment. They also examined the ability of response styles to predict treatment outcome and status at follow-up. Primary care patients (n = 96) with dysthymia or minor depression were randomly assigned to problem-solving therapy, paroxetine, or placebo. Patients' depressive symptoms and rumination, but not distraction, decreased over time. Pretreatment rumination and distraction were associated with more depressive symptoms at the conclusion of treatment; the latter finding was not consistent with the response style theory of depression. Results are discussed in terms of their implications for this theory.

Treating panic disorder in primary care: a collaborative care intervention

Efficacy research indicates the success of cognitive behavioral treatment and medication treatment for panic disorder with or without agoraphobia. However, research findings to date possess limited generalizability beyond specialty mental health settings. We present a model for collaborative care treatment for panic disorder in the primary care setting that combines cognitive behavioral therapy and medications, and involves a behavioral health specialist, psychiatrist, and primary care physician. Educational aids that are aimed to educate and activate patients to participate as partners in their care are provided. We outline the ways in which the standard treatment was modified, in light of the nature of the sample and setting, such as fewer sessions and management of comorbidity. Also, we provide evidence for acceptability of this intervention to primary care physicians and patients. This description is intended to lay the groundwork for continued research efforts in the extension of efficacious treatments into primary care settings.

Managed care, access to mental health specialists, and outcomes among primary care patients with depressive symptoms

OBJECTIVE

To determine whether managed care is associated with reduced access to mental health specialists and worse outcomes among primary care patients with depressive symptoms.

DESIGN

Prospective cohort study.

SETTING

Offices of 261 primary physicians in private practice in Seattle.

PATIENTS

Patients (N = 17,187) were screened in waiting rooms, enrolling 1,336 adults with depressive symptoms. Patients (n = 942) completed follow-up surveys at 1, 3, and 6 months.

MEASUREMENTS AND RESULTS

For each patient, the intensity of managed care was measured by the managedness of the patient's health plan, plan benefit indexes, presence or absence of a mental health carve-out, intensity of managed care in the patient's primary care office, physician financial incentives, and whether the physician read or used depression guidelines. Access measures were referral and actually seeing a mental health specialist. Outcomes were the Symptom Checklist for Depression, restricted activity days, and patient rating of care from primary physician. Approximately 23% of patients were referred to mental health specialists, and 38% saw a mental health specialist with or without referral. Managed care generally was not associated with a reduced likelihood of referral or seeing a mental health specialist. Patients in more-managed plans were less likely to be referred to a psychiatrist. Among low-income patients, a physician financial withhold for referral was associated with fewer mental health referrals. A physician productivity bonus was associated with greater access to mental health specialists. Depressive symptom and restricted activity day outcomes in more-managed health plans and offices were similar to or better than less-managed settings. Patients in more-managed offices had lower ratings of care from their primary physicians.

CONCLUSIONS

The intensity of managed care was generally not associated with access to mental health specialists. The small number of managed care strategies associated with reduced access were offset by other strategies associated with increased access. Consequently, no adverse health outcomes were detected, but lower patient ratings of care provided by their primary physicians were found.

Case review vs. usual care in primary care patients with depression: a pilot study

This paper reports on the results of a pilot study comparing the efficacy of an experimental case review program between psychiatrists and primary care physicians (PCPs) with PCPs' usual care on the outcome of depressive disorders at 1-year. The secondary aim of the paper is to identify correlates of remission of depressive disorders at the 1-year follow-up. The experimental case review program consisted of 12 biweekly meetings of primary care physicians with a psychiatrist. Meetings lasted two hours and were based on review of cases identified at the interview as suffering from full-blown or subthreshold conditions. Subjects were assessed at baseline, 3 months and 1 year. The baseline assessment included the Composite International Diagnostic Interview, the Hamilton Depression (HDRS) and Anxiety (HARS) Rating Scales, the Medical Outcomes Study SF-36 and some forms to collect life events, major difficulties, social support, and ongoing treatments. At 3 months patients received by mail the General Health Questionnaire (GHQ-12) and at one year the baseline clinical assessment was replicated. Assessments were conducted on eighty cases with major, minor or subsyndromal depression (SSD). The experimental case review program was similar in efficacy to usual care, with an average reduction of 5.5 points on the HAMD. Significant reduction in the severity of depression was associated with a limited number of baseline characteristics, such as being married and having minor depression as compared to major depression and SSD. On the contrary, chronic physical illness at baseline predicted a lower reduction of HAMD scores at one year. While major difficulties and life events during the one-year interval between the two assessments significantly predicted a poorer outcome, social support at home was related to a better outcome. This pilot study indicates that a case review intervention program is not efficacious in a mixed sample of patients with subsyndromal to major depression representative of the current practice of primary case physicians. Still, it might be worthwhile for "difficult" patients selected by the PCPs. In our sample, psychosocial factors seem to be important predictors of outcome. Future trials and large naturalistic studies are needed to address this key point.

Stressful life events and impulsiveness in failed suicide

The relationship of recent stressful life events with impulsiveness in triggering suicide attempts and how impulsiveness changes from one suicide attempt to another is unclear. This study used structured-interview tools and standardized measurements to examine the relationship between life stress and impulsiveness in a sample of patients who required hospitalization for a medically serious suicide attempt. After controlling for potentially confounding variables, the number of disrupted interpersonal relationships in the preceding year was a significant predictor of the impulsiveness of the suicide attempt, with three or more losses (but not other life stresses) associated with less impulsive attempts (T = 2.4, p = .02). Female gender (T = -1.98, p = .05) and lifetime DMS-III-R diagnoses (T = -2.45, p = .02) were significantly associated with more impulsive attempts. In 55 patients with at least two suicide attempts, impulsiveness, lethal intent, and communication of intent were significantly greater for the present compared to the prior attempt (p = 0.000). Certain stressful life events, gender, and total lifetime DSM-III-R diagnoses are associated with impulsiveness of failed suicide attempts; yet, impulsiveness is not necessarily consistent from one suicide attempt to another. This evidence supports and amplifies a stress-diathesis model of suicide behavior. Accordingly, efforts to increase personal resilience in individuals who have "failed suicide" may be more effective at preventing suicide morbidity than simple stress-reduction measures alone.

Predictors of nonresponse to treatment in primary care patients with dysthymia

Dysthymia is one of the most prevalent problems in primary care, especially in the elderly. In this study, we evaluated the demographic and clinical predictors of nonresponse to treatment in primary care patients with dysthymia. The study sample consisted of 338 primary care patients meeting DSMIII-R criteria for dysthymia from 4 diverse geographic sites in a randomized controlled 11-week trial of paroxetine, problem-solving therapy or placebo. Patients who attended at least 4 treatment sessions were used in the analysis. A score of less than 7 on the Hamilton was defined as a positive response to treatment. By Week 11, 52.2% of patients had a positive response to treatment. Patients with lower levels of education (odds ratio 0.44, 95% CI 0.23, 0.86), higher scores on the personality dimension of neuroticism (odds ratio 0.58, 95% CI 0.36, 0.92) and those with more severe medical illness (odds ratio 0.97, 95% CI 0.95, 0.99) were less likely to recover with either active or placebo treatments. Elderly women (>60 years of age; odds ratio 0.19, 95% CI 0.05, 0.66) were also less likely to respond to all treatments; however, females had a significantly higher response to placebo treatment compared to males. The factors associated with lack of response to treatment included lower-levels of education, high neuroticism, more severe medical illness and being an older female. This analysis is based on patients agreeing to participate in a randomized controlled trial, limiting representativeness of the sample, however, the demographic and clinical characteristics are common in elderly depressed primary care patients, and may signal the need for increased mental health specialty consultation.

Correlates of remission in primary care patients treated for minor depression

As minor depression is perhaps the most common form of mood disorder seen in primary care, we sought to explore the effects of both pharmacologic and psychosocial interventions for primary care patients with this condition. Three hundred and eighteen primary care patients meeting criteria for minor depression (defined as endorsing 3 or 4 of the nine DSM-IV symptoms of major depression, at least one of which was either depressed mood or anhedonia, for a period of at least four weeks, and scoring > or = 10 on the Hamilton Rating Scale for Depression) from 4 diverse geographic sites were enrolled in a randomized controlled 11 week trial of paroxetine, problem-solving therapy or placebo. Patients who attended at least 4 treatment sessions and who received a Hamilton score by an independent rater at either 6 or 11 weeks were used in the analysis (77% of enrolled patients). A score of < or = 6 on the Hamilton was defined as a positive response to treatment. Fifty four percent of patients met our criteria for remission (HRS-D < or = 6) by week 11, with no difference among treatments. Patients who were women, younger, of European descent, homemakers or retired persons (as opposed to unemployed) and who had lower baseline severity of depression were more likely to remit across all treatment conditions. Although explicitly addressed in the data analysis, differences in outcomes across the four sites of the investigations limit our confidence in the generalizabilty of our findings. In addition, patients with lower levels of educational attainment had a higher dropout rate, suggesting further caution about the generalizability of the findings. Defining remission in this categorical way, we found no differences among the interventions studied, but did find that outcome was related to demographic and clinical characteristics of the patients. While it is difficult to know why female patients were more likely to remit, this may be a function of the association in our subject populations between male gender and the likelihood (approximately .46) of being a patient in the VA system. The remaining variables associated with higher probability of remission appear to reflect social advantage and lower severity or complexity of illness.
