A planned care approach and patient registry to improve adherence to clinical guidelines for the diagnosis and management of attention-deficit/hyperactivity disorder.

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) affects almost 2.4 million US children. Because American Academy of Pediatrics guidelines for ADHD recommend use of standardized diagnostic instruments, regular follow-up and the chronic care model, this pilot project sought to implement and assess an electronic registry of patients with ADHD combined with care coordination by a planned care team. METHODS: This quality improvement project was structured with 2 intervention and 2 control clinics to facilitate evaluation of the use of a planned care system for management of ADHD. Care teams included a pediatrician, nurse, medical assistant, and care coordinator and tracked patients using an electronic registry with data drawn from the EMR. Clinical work flows were pilot tested to facilitate use of the Vanderbilt scales and their incorporation into the EMR at intervention sites. Outcome measures included 2 recommended clinical follow-ups based on HEDIS measures as well as use of the Vanderbilt rating scales. Initiation phase measure was for follow-up after initiating medication, while the continuation phase measure was for subsequent follow-up during the first year of treatment. Measures were monitored during the project year and then also in the ensuing period of spread of the intervention to other sites. RESULTS: Although the modified HEDIS initiation phase measure for patients newly on medication remained static at approximately 50% throughout the project period, the continuation phase measure showed improvement from 35% at baseline to 45% at the end of the project assessment year, a 29% increase. Follow-up for patients stable on medications also remained unchanged during the project period, but during subsequent spreading of the intervention to nonproject sites, follow-up of these patients improved to over 90%. In adjusted analyses, patients with ADHD at intervention sites were over 2 times more likely than patients at control sites to have had a Vanderbilt score documented in their records. CONCLUSIONS: The project achieved modest improvements in the diagnostic and treatment process for patients with ADHD. The use of a planned care system and electronic patient registry shows promise for improving the diagnosis and treatment process for patients with ADHD.

Differences in risk factors for suicide attempts among 9th and 11th grade youth: a longitudinal perspective.

The purpose of the study is to assess the relationship between timing of adolescent development and risk factors for suicide. Nationally representative data from the Add Health survey were used. The relationship of sociodemographic characteristics, known risk factors, and physical developmental timing and cognitive developmental style to suicide attempt was assessed. Depression was a risk factor for suicide attempts in both 9th and 11th grade. Other risk factors differed. Use of illegal drugs, homosexual orientation, using public assistance, and physical development were the important risk factors for ninth graders. For 11th graders, sexual abuse, being in counseling, and being of "other" race or ethnicity (mainly Asian or Native American) were risk factors. The cognitive development variable of using a systematic problem-solving method was protective for 11th graders. Recognizing that risk factors for adolescent suicide attempts change over time and with developmental timing of puberty is an important factor for suicide prevention strategies.

Posttraumatic stress disorder and intimate partner violence in a women's headache center.

BACKGROUND: Posttraumatic stress disorder has been linked to women's ill health, including headaches. Intimate partner violence, which may result in posttraumatic stress disorder, is often reported by women with headaches. Prior studies of intimate partner violence and headache have estimated lifetime but not 12-month prevalence. The researchers in this study examined the relationship between headache and posttraumatic stress disorder in a novel population, and estimated 12-month and lifetime prevalence rates of intimate partner violence. METHODS: Patients were recruited from a women's headache center (n = 92) during 2006-07 and completed the Migraine Disability Assessment measure of headache severity. Posttraumatic stress disorder was measured using a modified Breslau scale. Twelve-month and lifetime physical intimate partner violence were measured with the Partner Violence Screen and the STaT ("slapped, threatened and throw") measure. Multivariable regression determined factors independently associated with headache severity. RESULTS: Among all participants, 28.3% screened positive for posttraumatic stress disorder; 9.8% and 36.9% of women endorsed recent and lifetime intimate partner violence. Posttraumatic stress disorder was strongly associated with headache severity (ß = 34.12, p = 0.01). Patients reporting lifetime intimate partner violence exhibited a trend of nine additional days of disability due to headache over 90 days. CONCLUSIONS: Posttraumatic stress disorder and intimate partner violence occur among a sizable proportion of women referred for headache. The authors' findings reaffirm that clinicians treating women with headaches must be aware of the possibility of posttraumatic stress disorder and intimate partner violence in such patients.

Asian student depression in American high schools: differences in risk factors.

There are inconsistent findings about depression in Asians. This study examined risk factors for depression in Asian and Caucasian adolescents. Stratified bivariate secondary analyses of risk indicators and depressed mood were performed in this cross-sectional study of high school survey data (9th to 12th grades) from 2,542 students (198 Asian). Asians had a higher prevalence of depressed symptoms, but similar risk factors as Caucasians. Smoking and injury at work were major risk factors for depressed mood among Asians. Asian-specific risk factors for depression were being foreign-born and having a work-related injury. Asian and Caucasian teens have similar risk factors for depressed mood, though being foreign born and having a work-related injury are risk factors specific to Asian youth, possibly related to social-economic status. Providers of care in school, such as school nurses, can be important primary screeners of depression for Asian students in particular.

Lifetime and during pregnancy experience of violence and the risk of low birth weight and preterm birth.

In order to assess the relationship between lifetime and during pregnancy experience of violence and low birth weight (LBW) and preterm birth outcomes, we designed a prospective cohort study in which the birth outcomes of women who experienced violence before their pregnancy or who experienced violence during pregnancy were compared to women who reported no lifetime experience of violence. We found that the risk of having a low birth weight or preterm baby was higher for women who did not experience violence. The proportion of women who had LBW babies was 7.1% for women who experienced violence during pregnancy, 7.8% for women who experienced violence before the current pregnancy, and 9.1% for nonexposed women. The proportion of preterm births was 3.5% for women exposed to violence during pregnancy, 8.5% for women exposed before the current pregnancy, and 9.7% for nonexposed women. However, married women who experienced violence had a higher proportion of LBW and preterm infants compared to the reference group of nonvictims of violence. Overall, women who experienced violence during pregnancy and before their current pregnancy did not have a greater proportion of LBW babies or preterm births. The findings suggest that married women in certain populations may experience more frequent or more severe experience of violence than unmarried women.

Patient follow-up in primary care after behavioral health screening in an urban public hospital system: a prospective, observational study of 2686 patients.

OBJECTIVE: Patients with psychiatric conditions are known to experience poor and often disparate health outcomes. To investigate one potential mechanism for this phenomenon, we examined whether patients who screen positive for psychiatric comorbidity are lost to follow-up from primary care at higher rates than screen-negative controls. METHOD: Patients in a public hospital system were followed prospectively for an 18-month period after an initial routine behavioral health screening in neighborhood health centers. Screening data were linked to electronic medical record visit data, and loss to follow-up was ascertained using Cox proportional hazards modeling. RESULTS: A public hospital health program screened 2686 patients from March 1998 to December 2000, and their visits were counted prospectively for 18 months. Nearly one third (N = 772, 29%) screened positive for a psychiatric condition. The screen-positive group had lower rates of censoring and a shorter time-to-event than the controls, indicating a higher continuing visit rate in primary care. This relationship persisted after adjustment for demographic variables, insurance type, substance abuse, and violence exposure. CONCLUSION: Patients who screen positive for psychiatric comorbidity are not lost to follow-up at higher rates than screen-negative controls. This finding suggests that disparate outcomes for mentally ill patients in a public hospital system may not be based on reduced access to or lack of contact with primary care providers. Further study of systems or provider-related factors is needed to ascertain the pathways toward poor health for this population.

A comparison of maternal interview and medical record ascertainment of violence among women who had poor pregnancy outcomes.

OBJECTIVES: This study investigated the agreement between self-reported and medical record assessment of exposure to violence and the impact of misclassification on the estimation of the association between exposure to violence and infant death and very low birthweight. METHODS: The study population consisted of women who participated in two case-control studies on infant death and very low birthweight. There were 254 pairs of interviews and medical record reviews available for comparison. RESULTS: A total of 153 women (60.2%) reported ever being exposed to violence--92 (60.1%) based on the interview only, 18 (11.8%) based on the medical record only, and 43 (28.1%) in both sources. The sensitivity of the violence variables was low, ranging from 16.9% to 31.9% and kappa statistics showed poor agreement. Lower rates of all types of violence were found through the medical record than through the interview. CONCLUSION: Prevalence of violence based on medical record alone had a high degree of misclassification and some odds ratios were biased toward the null. Studies in which violence is an exposure, outcome, or confounder must use participant interviews in order to gather accurate information. A combination of sources may be the most accurate.

Developmental differences in risk factors for suicide attempts between ninth and eleventh graders.

In order to identify differences in risk factors for suicide attempts throughout adolescence, this study utilized a school-based survey of ninth (n = 1,192) and eleventh graders (N = 1,055). Suicide attempts were associated with cigarette and alcohol use, family violence, and depression for ninth graders and with illicit drug use, school violence, and sexual abuse for eleventh graders, while having friends was protective for both groups. Additionally, having more than one risk factor imparted an exponential risk for suicide attempts (ninth > eleventh graders). The differences detected are consistent with developmental changes of adolescence and represent important information for identification of at-risk youth.
