Use of the Montreal Cognitive Assessment and Alzheimer's Disease-8 as cognitive screening measures in Parkinson's disease.

OBJECTIVE: To examine the sensitivity and specificity of the Montreal Cognitive Assessment (MoCA), a brief cognitive screening measure previously validated for use in Parkinson's disease (PD), and Alzheimer's Disease-8 (AD8), an eight-item informant report used to screen for dementia, but not yet validated for use in PD, to identify cognitive impairment in a sample of 111 patients with PD. METHODS: Cognitive impairment was determined based on a battery of neuropsychological measures, excluding the MoCA and AD8. Classification rates of both the MoCA and AD8 in identifying cognitive impairment were examined using logistic regression and receiver operator characteristic (ROC) analysis. Optimal cutoff scores were determined to maximize sensitivity and specificity. RESULTS: The MoCA correctly classified 78.4% of participants (p < 0.001), and ROC analysis yielded an area under the curve (AUC) of 0.82. A MoCA cutoff score of <25 yielded optimal sensitivity (0.77) and specificity (0.79) for identifying PD patients with cognitive impairment. Similar analyses for the AD8 were statistically nonsignificant, although the classification rate was 70.5%, with an AUC of 0.50. CONCLUSIONS: These results provide additional support for the MoCA, but not the AD8, in identifying cognitive impairment in patients with PD.

A Survey Comparing Delegation of Cosmetic Procedures Between Dermatologists and Nondermatologists.

BACKGROUND: How delegation of procedures varies among cosmetic specialties in the United States is not well described. OBJECTIVE: To better describe current practices in delegation of procedures to nonphysicians among physicians of different cosmetic specialties in the United States. METHODS: An Internet-based survey was administered to physician members of the American Society for Dermatologic Surgery (ASDS), the American Society for Aesthetic Plastic Surgery (ASAPS), and the American Society for Laser Medicine and Surgery (ASLMS). RESULTS: A total of 823 responses were collected. Two hundred ninety-one of the 521 dermatologists (55.9%) reported delegating cosmetic procedures compared with 223 of the 302 nondermatologists (73.8%) (p < .05). When delegation occurred, dermatologists were more likely than nondermatologists to delegate the following procedures to higher level non-physician providers (NPP): chemical peels, neuromodulator and filler injections, laser hair removal, pulsed dye laser, tattoo removal, intense pulsed light, nonablative fractional laser, and sclerotherapy. No difference in delegation rate was noted between dermatologists and non-dermatologist physicians with respect to microdermabrasion, ablative fractional laser, cryolipolysis, radiofrequency skin tightening, focused ultrasound skin tightening, and focused ultrasound fat reduction. CONCLUSION: Dermatologists delegate procedures to NPP less frequently than non-dermatologist physicians, and when they do, it is typically to higher level NPP.

Internal consistency: reports of its death are premature.

McCrae, Kurtz, Yamagata, and Terracciano (Personality and Social Psychology Review 15:28-50, 2011) presented data supporting the position that test-retest reliability is more important for methods of personality assessment than is internal-consistency reliability. We raise two points not adequately considered in their findings. First, not all personality assessment is concerned with assessing traits, for which temporal stability is clearly important. Much research (e.g., therapy outcome studies) is concerned with assessing states, in which an emphasis on temporal stability can lead to the underestimation of change. Second, we suggest that using the literature as a basis for their position causes the role of internal consistency to be underestimated. This is because manuscripts are frequently rejected because their measures possess low internal consistency, but are rarely rejected because of low temporal stability. Thus, the effects of internal consistency are range-restricted to an unknown amount, because investigators do not have access to studies that have been rejected due to low internal consistency.

The Quick Inventory of Depressive Symptomatology, Adolescent Version (QIDS-A17): A Psychometric Evaluation.

Objective: The current study aimed to evaluate the psychometric features of the Quick Inventory of Depressive Symptomatology, Adolescent version (QIDS-A17) and the clinician-rated Children's Depression Rating Scale-Revised (CDRS-R). Methods: Altogether, 103 outpatients (8 to 17 years) completed the self-report QIDS-A17-SR. Clinician interviews of adolescents (QIDS-A17-C (Adolescent)) and of parents (QIDS-A17-C (Parent)) were combined to create the QIDS-A17-C(Composite) and the CDRS-R. Results: All QIDS-A17 measures and the CDRS-R evidenced high total score correlations and internal consistency. Factor analysis found all four measures to be unidimensional. Item Response Theory (IRT) analysis found results that complemented the reliability results found in CTT. All four also demonstrated discriminant diagnostic validity based on logistic regression and ANOVA analyses. Conclusion: The psychometric properties of the self-report and composite versions of the QIDS-A17 suggest acceptability as a measure of depression in adolescents either as a measure of depressive symptoms or severity of illness in adolescents. The self-report version may be a helpful tool in busy clinical practices.

The quick inventory of depressive symptomatology (clinician and self-report versions) in patients with bipolar disorder.

INTRODUCTION: The clinical and self-report versions of the Quick Inventory of Depressive Symptomatology (QIDS-C16 and QIDS-SR16) have been well studied in patients with major depressive disorder and in one recent study using patients with bipolar disorder. This article examines these measures in a second sample of 141 outpatients with bipolar disorder in different phases of the illness. METHODS: At baseline, 61 patients were depressed and 30 were euthymic; at exit, 50 were depressed and 52 were euthymic. The remaining patients (at baseline or exit) were in either a manic or mixed phase and were pooled for statistical reasons. RESULTS: Similar results were found for the QIDS-C16 and QIDS-SR16. Scores were reasonably reliable to the extent that variability within groups permitted. As expected, euthymic patients showed less depressive symptomatology than depressed patients. Sad mood and general interest were the most discriminating symptoms between depressed and euthymic phases. Changes in illness phase (baseline to exit) were associated with substantial changes in scores. The relation of individual depressive symptoms to the overall level of depression was consistent across phases. CONCLUSION: Both the QIDS-SR16 and QIDS-C16 are suitable measures of depressive symptoms in patients with bipolar disorder.

A Comparison of the QIDS-C16, QIDS-SR16, and the MADRS in an Adult Outpatient Clinical Sample.

BACKGROUND: This study compared the 16-item Clinician and Self-Report versions of the Quick Inventory of Depressive Symptomatology (QIDS-C16 and QIDS-SR16) and the 10-item Montgomery-Asberg Depression Rating Scale (MADRS) in adult outpatients. The comparison was based on psychometric features and their performance in identifying those in a major depressive episode as defined by the Mini-International Neuropsychiatric Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. METHODS: Of 278 consecutive outpatients, 181 were depressed. Classical test theory, factor analysis, and item response theory were used to evaluate the psychometric features and receiver operating characteristic (ROC) analyses. RESULTS: All three measures were unidimensional. All had acceptable reliability (coefficient a=.87 for MADRS10, .82 for QIDS-C16, and .80 for QIDS-SR16). Test information function was higher for the MADRS (ie, it was most sensitive to individual differences in levels of depression). The MADRS and QIDS-C16 slightly but consistently outperformed the QIDS-SR16 in differentiating between depressed versus nondepressed patients. CONCLUSION: All three measures have satisfactory psychometric properties and are valid screening tools for a major depressive episode.

A psychometric evaluation of the clinician-rated Quick Inventory of Depressive Symptomatology (QIDS-C16) in patients with bipolar disorder.

The clinician-rated, 16-item Quick Inventory of Depressive Symptomatology (QIDS-C16) has been extensively evaluated in patients with major depressive disorder (MDD). This report assesses the psychometric properties of the QIDS-C16 in outpatients with bipolar disorder (BD, N = 405) and MDD (N = 547) and in bipolar patients in the depressed phase only (BD-D) (N = 99) enrolled in the Texas Medication Algorithm Project (TMAP) using classical test theory (CTT) and the Samejima graded item response theory (IRT) model. Values of coefficient alpha were very similar in BD, MDD, and BD-D groups at baseline (alpha = 0.80-0.81) and at exit (alpha = 0.82-0.85). The QIDS-C16 was unidimensional for all three groups. MDD and BD-D patients (n = 99) had comparable symptom levels. The BD-D patients (n = 99) had the most, and bipolar patients in the manic phase had the least depressive symptoms at baseline. IRT analyses indicated that the QIDS-C16 was most sensitive to the measurement of depression for both MDD patients and for BD-D patients in the average range. The QIDS-C16 is suitable for use with patients with BD and can be used as an outcome measure in trials enrolling both BD and MDD patients.

A single blind comparison of lithium and lamotrigine for the treatment of bipolar II depression.

BACKGROUND: Treatment studies are lacking for patients with bipolar II disorder (BDII). The objective of this study was to compare lamotrigine (LTG) and lithium (Li) monotherapy for the treatment of BDII depression. METHODS: Patients with BDII acute depression were randomized to open-label monotherapy with LTG or Li, and evaluated by trained raters blinded to treatment. Patients were titrated to 200 mg/day of LTG over 8 weeks or at least 900 mg/day of Li over 2 weeks (serum level 0.6-1.2 mEq/L), and seen biweekly for 16 weeks. The primary outcome variable was change in the Hamilton Depression Rating Scale 17-item (Ham-D(17)), evaluated using mixed effects random regression. RESULTS: Both groups showed significant improvement from baseline to endpoint on the Ham-D(17) (p<0.0001), with no between group differences (p=0.95). Seventy-two percent of the population was rapid cycling by DSM-IV criteria. No differences in response were noted between rapid cyclers and non-rapid cyclers. Early termination for any cause was 42%. The Li group reported significantly more side effects, although drop-out due to side effects did not differ between groups. LIMITATIONS: This study was limited by an open treatment design, a lack of placebo arm, and uneven treatment groups. CONCLUSIONS: Lamotrigine and lithium were effective monotherapy for BDII depression, with comparable response and remission rates. Naturalistic design and lack of placebo limit conclusions, though patient history indicated long standing depression unlikely to be alleviated by time. Patients who received Li reported more side effects, but this did not appear to impact drop-out rates.

Are bipolar mood symptoms affected by the phase of the menstrual cycle?

BACKGROUND: Evidence suggests gender differences may exist in bipolar disorder, and a review of the literature shows that more women than men may experience rapid-cycling bipolar disorder. The issues contributing to these gender differences are unknown; a number of case reports have indicated the possibility of mood changes secondary to hormonal influences during the menstrual cycle. We sought to examine the relationship between bipolar disorder and menstrual cycle-related mood changes. To our knowledge, this is one of the largest samples in the literature addressing this issue. METHODS: Outpatient women with bipolar disorder I, bipolar disorder II, and not otherwise specified (NOS), between the ages of 18 and 45, were evaluated. The National Institute of Mental Health Life Chart Method-p (NIMH-LCM-p) was used for daily mood ratings of depression and mania. Repeated measures of ANOVA and t tests were conducted separately for depressive and for manic symptom scores. RESULTS: One hundred nineteen women met the age criterion, and only 41 women met the rest of the inclusion criteria. In this sample of 41 women, there was no significant relationship between phases of the menstrual cycle (early and late follicular and early and late luteal phases) and changes in depression or mania. In an exploratory examination, 8 of 41 women showed a numerically higher mean depression score in the luteal phase than in the follicular phase; 5 of 41 women showed a numerically higher mean mania score in the luteal phase than in the follicular phase of the menstrual cycle. CONCLUSIONS: Different phases of the menstrual cycle were unrelated to depression and mania in a heterogeneous group of women with bipolar disorder. Prospective studies are needed to identify a vulnerable subpopulation in a homogeneous clinical sample.

Attitudes and Beliefs of Pediatric Surgical Specialists on Costs of Care and High Deductible Health Plans.

Health care consumers are burdened with rising out-of-pocket medical expenses. Surgical specialists' experience and attitude towards patients' out-of-pocket costs and the influence of these factors on healthcare utilization are unknown. Our aim was to define the pediatric surgeons' experience with the financial concerns of their patients. Members from the American Academy of Pediatrics Sections on Plastic Surgery, Surgery and Urology were surveyed. Analysis of variance was used to investigate practice differences. Two hundred and eighteen out of 973 surgeons representing 38 states completed the survey. Nearly half of the surveyed surgeons did not know if cost was a determinant for their patients' choice in surgical facility, or if parents compared costs prior to the visit. Eighty four per cent of the surgeons would consider patient costs if medically appropriate, to entertain less costly alternatives, and adjust surgical scheduling to decrease economic burden. Most pediatric surgical specialists are unaware if out-of-pocket costs influenced patients' preoperative decisions. Nonetheless, they are sympathetic to the issue. As the financial burden of health care shifts to consumers, our survey indicates that surgeons are open to candid discussion surrounding finances and may alter recommendations accordingly if appropriate.

Clinical vs. self-report versions of the quick inventory of depressive symptomatology in a public sector sample.

OBJECTIVES: Recent work using classical test theory (CTT) and item response theory (IRT) has found that the self-report (QIDS-SR(16)) and clinician-rated (QIDS-C(16)) versions of the 16-item quick inventory of depressive symptomatology were generally comparable in outpatients with nonpsychotic major depressive disorder (MDD). This report extends this comparison to a less well-educated, more treatment-resistant sample that included more ethnic/racial minorities using IRT and selected classical test analyses. METHODS: The QIDS-SR(16) and QIDS-C(16) were obtained in a sample of 441 outpatients with nonpsychotic MDD seen in the public sector in the Texas Medication Algorithm Project (TMAP). The Samejima graded response IRT model was used to compare the QIDS-SR(16) and QIDS-C(16). RESULTS: The nine symptom domains in the QIDS-SR(16) and QIDS-C(16) related well to overall depression. The slopes of the item response functions, a, which index the strength of relationship between overall depression and each symptom, were extremely similar with the two measures. Likewise, the CTT and IRT indices of symptom frequency (item means and locations of the item response functions, b(i) were also similar with these two measures. For example, sad mood and difficulty with concentration/decision making were highly related to the overall depression severity with both the QIDS-C(16) and QIDS-SR(16). Likewise, sleeping difficulties were commonly reported, even though they were not as strongly related to overall magnitude of depression. CONCLUSION: In this less educated, socially disadvantaged sample, differences between the QIDS-C(16) and QIDS-SR(16) were minor. The QIDS-SR(16) is a satisfactory substitute for the more time-consuming QIDS-C(16) in a broad range of adult, nonpsychotic, depressed outpatients.

A psychometric evaluation of the CDRS and MADRS in assessing depressive symptoms in children.

OBJECTIVE: This study compared the psychometric properties of the Children's Depression Rating Scale-Revised (CDRS-R) and the Montgomery-Asberg Depression Rating Scale (MADRS) in children with major depressive disorder. METHOD: Children (N = 96; ages 8 to 11 years inclusive) with nonpsychotic major depressive disorder were enrolled. Participants were part of a multisite, outpatient, randomized, placebo-controlled, 9-week trial of fluoxetine (10 mg/day for the first week and 20 mg/day thereafter). The CDRS-R and MADRS were completed based on clinician interviews with both parents and children. Classic test theory and item response theory analyses were conducted. RESULTS: The MADRS and CDRS-R total scores were correlated at baseline (r = 0.51) and at study exit (r = 0.85). Cronbach's alpha was .86 (CDRS-R) and .82 (MADRS) at exit. The effect sizes for change from baseline to exit between the fluoxetine and placebo groups were 0.78 (CDRS-R) and 0.61 (MADRS). There was agreement between the CDRS-R and MADRS in the declaration of treatment response (50% improvement from baseline to exit) in 84.2% of children. Test information function favored the CDRS-R. CONCLUSIONS: The CDRS-R showed greater effect size for differentiating drug and placebo and better test information than the MADRS in this study of depressed children.

The Treatment of Chronic Coccydynia and Postcoccygectomy Pain With Pelvic Floor Physical Therapy.

BACKGROUND: Coccydynia is a challenging disorder that often is refractory to treatments such as medications and injections. Physical therapy for coccydynia rarely has been studied. OBJECTIVE: To evaluate the efficacy of pelvic floor physical therapy for reducing pain levels in patients with coccydynia. DESIGN: Retrospective chart review. SETTING: The pelvic floor rehabilitation clinic of a major university hospital. PATIENTS: A total of 124 consecutive patients over age 18 with a chief complaint of coccydynia between 2009 and 2012. A subgroup of 17 of the 124 patients had previously undergone coccygectomy with continued pain postoperatively. METHODS OR INTERVENTIONS: The primary treatment intervention was pelvic floor physical therapy aimed at pelvic floor muscle relaxation. Secondary treatment interventions included the prescription of baclofen for muscle relaxation (19% of patients), ganglion impar blocks (8%), or coccygeus trigger point injections (17%). MAIN OUTCOME MEASURES: Primary outcome measures included final minimum, average, and maximum pain numeric rating scales. A secondary outcome measure was the patient's subjective percent global improvement assessment. Baseline demographics were used to determine which pretreatment characteristics were correlated with treatment outcomes. RESULTS: Of the 124 patients, 93 participated in pelvic floor physical therapy and were included in statistical analysis. For the 79 patients who completed treatment (with a mean of 9 physical therapy sessions), the mean average pain ratings decreased from 5.08 to 1.91 (P < .001) and mean highest pain ratings decreased from 8.81 to 4.75 (P < .001). The mean percent global improvement was 71.9%. Mean average pain ratings in postcoccygectomy patients improved from 6.64 to 3.27 (P < .001). Greater initial pain scores and a history of previous injections were correlated with P < .001 pain scores on completion of physical therapy. Pain duration and history of trauma did not affect treatment outcomes. CONCLUSIONS: Pelvic floor physical therapy is a safe and effective method of treating coccydynia. LEVEL OF EVIDENCE: III.

An evaluation of the quick inventory of depressive symptomatology and the hamilton rating scale for depression: a sequenced treatment alternatives to relieve depression trial report.

BACKGROUND: Nine DSM-IV-TR criterion symptom domains are evaluated to diagnose major depressive disorder (MDD). The Quick Inventory of Depressive Symptomatology (QIDS) provides an efficient assessment of these domains and is available as a clinician rating (QIDS-C16), a self-report (QIDS-SR16), and in an automated, interactive voice response (IVR) (QIDS-IVR16) telephone system. This report compares the performance of these three versions of the QIDS and the 17-item Hamilton Rating Scale for Depression (HRSD17). METHODS: Data were acquired at baseline and exit from the first treatment step (citalopram) in the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) trial. Outpatients with nonpsychotic MDD who completed all four ratings within +/-2 days were identified from the first 1500 STAR*D subjects. Both item response theory and classical test theory analyses were conducted. RESULTS: The three methods for obtaining QIDS data produced consistent findings regarding relationships between the nine symptom domains and overall depression, demonstrating interchangeability among the three methods. The HRSD17, while generally satisfactory, rarely utilized the full range of item scores, and evidence suggested multidimensional measurement properties. CONCLUSIONS: In nonpsychotic MDD outpatients without overt cognitive impairment, clinician assessment of depression severity using either the QIDS-C16 or HRSD17 may be successfully replaced by either the self-report or IVR version of the QIDS.

Making clinicians lives easier: guidance on use of the QIDS self-report in place of the MADRS.

BACKGROUND: The ability to convert total scores from one scale to another facilitates the interpretation of research findings and facilitates the use of systematic measurement in clinical practice. METHODS: Item Response Theory methods were used to convert total scores between the 16-item Quick Inventory of Depressive Symptomatology (QIDS-SR16) and the Montgomery Asberg Depression Rating Scale (MADRS) total scores. Data were obtained from a sample of 233 outpatients with highly treatment-resistant, nonpsychotic major depressive episodes participating in a one-year open label study of vagus nerve stimulation to augment psychotropic medication treatment. RESULTS: MADRS total scores averaged 31.9 (SD = 6.7) at baseline and 21.9 (SD = 11.0) at one year. QIDS-SR16 total scores averaged 17.6 (SD = 3.6) at baseline and 12.5 (SD = 5.8) at one year. Based on one-year data (or exit if the patient did not complete one year), corresponding QIDS-SR16 and MADRS total scores were presented for each possible QIDS-SR16 and MADRS total score. A QIDS-SR16 total score of 5 was comparable to a MADRS total score of 7 or 8 (7.5). LIMITATION: The degree to which these results generalize to less treatment-resistant samples is unknown. CONCLUSION: The conversion of QIDS-SR16 and MADRS total scores provides a basis for clinicians who wish to use the QIDS-SR16 to understand what MADRS total scores reported in clinical trials approximate QIDS-SR16 total scores obtained with their patients.

The Parkland Burn Center experience with 297 cases of child abuse from 1974 to 2010.

INTRODUCTION: Pediatric burns due to abuse are unfortunately relatively common, accounting for 5.8-8.8% of all cases of abuse annually. Our goal was to evaluate our 36-year experience in the evaluation and management of the victims of abuse in the North Texas area. METHODS: A prospectively maintained database containing records on all admissions from 1974 through 2010 was queried for all patients aged less than 18 years. Patients admitted for management of a non-burn injury were excluded from the analysis. RESULTS: Of 5,553 pediatric burn admissions, 297 (5.3%) were due to abuse. Children with non-accidental injuries tended to be younger (2.1 vs. 5.0 years, p<0.0001) and male (66.0 vs. 56.5%, p=0.0008). Scald was the most common mechanism of injury overall (44.8%), and was also the predominant cause of inflicted burns (89.6 vs. 42.3%, p<0.0001). Multivariate logistic regression identified age, gender, presence of a scald, contact, or chemical burn, and injury to the hands, bilateral feet, buttocks, back, and perineum to be significant predictors of abuse. Victims of abuse were also found to have worse outcomes, including mortality (5.4 vs. 2.3%, p=0.0005). After adjusting for age, mechanism of injury, and burn size, abuse remained a significant predictor of mortality (OR 3.3, 95% CI 1.5-7.2) CONCLUSIONS: Clinicians should approach all burn injuries in young children with a high index of suspicion, but in particular those with scalds, or injuries to the buttocks, perineum, or bilateral feet should provoke suspicion. Burns due to abuse are associated with worse outcomes, including length of stay and mortality.

Evaluation of anhedonia with the Snaith-Hamilton Pleasure Scale (SHAPS) in adult outpatients with major depressive disorder.

Anhedonia or inability to experience pleasure not only is a core symptom of major depressive disorder (MDD), but also is identified as an important component of the positive valence system in the NIMH Research Domain Criteria. The Snaith-Hamilton Pleasure Scale (SHAPS) has been developed for the assessment of hedonic experience or positive valence, but has not been well-studied in depressed outpatient populations. The current study examined the reliability and validity of the SHAPS using a sample of adult outpatients with treatment resistant MDD. Data for the current study were obtained from 122 adult outpatients with a diagnosis of MDD and non-response to adequate treatment with an SSRI and who participated in Project TReatment with Exercise Augmentation for Depression (TREAD). A Principal Components Analysis was used to define the dimensionality of the SHAPS. Convergent and discriminant validity were evaluated via correlations of the SHAPS total score with "gold standard" measures of depression severity and quality of life. The SHAPS was found to have high internal consistency (Cronbach's coefficient α = .82). A Principal Components Analysis suggests that the SHAPS is mainly "unidimensional" and limited to hedonic experience among adult outpatients with MDD. Convergent and discriminant validity were assessed by examining the Spearman rank-order correlation coefficient between the SHAPS total score and the HRSD17 (rs = 0.22, p < .03), IDS-C30 (rs = 0.26, p < .01), IDS-SR30 (rs = 0.23, p < .02), QIDS-C16 (rs = 0.22, p < .03), QIDS-SR16 (rs = 0.17, p < .10), QLES-Q (rs = -0.32, p < .002), and the pleasure/enjoyment item (sub-item 21) of the IDS-C (rs = 0.44, p < .0001) and IDS-SR (rs = 0.38, p < .0002). The self-administered SHAPS showed modest sensitivity (76%) and specificity (54%) with the self-administered pleasure/enjoyment single item (sub-item 21) of IDS-SR30. The current study shows that the SHAPS is a reliable and valid instrument to assess hedonic experience or positive valence in adult outpatients with MDD and provides a broader assessment of this important domain.

Self-rated measure of pain frequency, intensity, and burden: psychometric properties of a new instrument for the assessment of pain.

BACKGROUND: A brief, self-administered measurement of pain frequency, intensity, and burden is desirable in both research and clinical settings. We describe the development and initial psychometric properties of a new instrument, the Pain Frequency, Intensity, and Burden Scale (P-FIBS). METHODS: The P-FIBS was administered to all participants (N = 302) with psychostimulant use disorders in the National Institute on Drug Abuse Clinical Trials Network's STRIDE (Stimulant Reduction Intervention using Dose Exercise) multisite trial. RESULTS: The four items on the P-FIBS demonstrate high item-total correlations (range 0.70-0.85) with a high Cronbach's alpha (0.90). The P-FIBS demonstrated a strong negative correlation with the bodily pain sub-score of the Short Form Health Survey (r = -0.76, p < 0.0001) and did not correlate with a measure of cocaine (r = 0.09, p = 0.12) or methamphetamine (r = -0.06, p = 0.33) craving. CONCLUSIONS: The P-FIBS demonstrates good psychometric properties. This brief measure can be used to assess pain in research settings or as a screen in clinical settings. Further research is needed to assess the measure's sensitivity to change with treatment.

The Parkland Protocol's modified Berne-Norwood criteria predict two tiers of risk for traumatic brain injury progression.

As a basis for venous thromboembolism (VTE) prophylaxis after traumatic brain injury (TBI), we have previously published an algorithm known as the Parkland Protocol. Patients are classified by risk for spontaneous progression of hemorrhage with chemoprophylaxis regimens tailored to each tier. We sought to validate this schema. In our algorithm, patients with any of the following are classified "low risk" for spontaneous progression: subdural hemorrhage ≤8 mm thick; epidural hemorrhage ≤8 mm thick; contusions ≤20 mm in diameter; a single contusion per lobe; any amount of subarachnoid hemorrhage; or any amount of intraventricular hemorrhage. Patients with any injury exceeding these are "moderate risk" for progression, and any patient receiving a monitor or craniotomy is "high risk." From February 2010 to November 2012, TBI patients were entered into a dedicated database tracking injury types and sizes, risk category at presentation, and progression on subsequent computed tomgraphies (CTs). The cohort (n=414) was classified as low risk (n=200), moderate risk (n=75), or high risk (n=139) after first CT. After repeat CT scan, radiographic progression was noted in 27% of low-risk, 53% of moderate-risk, and 58% of high-risk subjects. Omnibus analysis of variance test for differences in progression rates was highly significant (p<0.0001). Tukey's post-hoc test showed the low-risk progression rate to be significantly different than both the moderate- and high-risk arms; no difference was noted between the moderate- and high-risk arms themselves. These criteria are a valid tool for classifying TBI patients into two categories of risk for spontaneous progression. This supports tailored chemoprophylaxis regimens for each arm.
