An Integrated Care Pathway for depression in adolescents: protocol for a Type 1 Hybrid Effectiveness-implementation, Non-randomized, Cluster Controlled Trial. BMC Psychiatry 2024; 24:193. [PMID: 38459453 PMCID: PMC10921633 DOI: 10.1186/s12888-023-05297-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Accepted: 10/22/2023] [Indexed: 03/10/2024] Open
Abstract
INTRODUCTION Our group developed an Integrated Care Pathway to facilitate the delivery of evidence-based care for adolescents experiencing depression called CARIBOU-2 (Care for Adolescents who Receive Information 'Bout OUtcomes, 2nd iteration). The core pathway components are assessment, psychoeducation, psychotherapy options, medication options, caregiver support, measurement-based care team reviews and graduation. We aim to test the clinical and implementation effectiveness of the CARIBOU-2 pathway relative to treatment-as-usual (TAU) in community mental health settings. METHODS AND ANALYSIS We will use a Type 1 Hybrid Effectiveness-Implementation, Non-randomized Cluster Controlled Trial Design. Primary participants will be adolescents (planned n = 300, aged 13-18 years) with depressive symptoms, presenting to one of six community mental health agencies. All sites will begin in the TAU condition and transition to the CARIBOU-2 intervention after enrolling 25 adolescents. The primary clinical outcome is the rate of change of depressive symptoms from baseline to the 24-week endpoint using the Childhood Depression Rating Scale-Revised (CDRS-R). Generalized mixed effects modelling will be conducted to compare this outcome between intervention types. Our primary hypothesis is that there will be a greater rate of reduction in depressive symptoms in the group receiving the CARIBOU-2 intervention relative to TAU over 24 weeks as per the CDRS-R. Implementation outcomes will also be examined, including clinician fidelity to the pathway and its components, and cost-effectiveness. ETHICS AND DISSEMINATION Research ethics board approvals have been obtained. Should our results support our hypotheses, systematic implementation of the CARIBOU-2 intervention in other community mental health agencies would be indicated.

Systematic Review: The Measurement Properties of the Suicidal Ideation Questionnaire and Suicidal Ideation Questionnaire-Jr. J Am Acad Child Adolesc Psychiatry 2023:S0890-8567(23)02264-5. [PMID: 38154613 DOI: 10.1016/j.jaac.2023.10.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Revised: 10/02/2023] [Accepted: 12/19/2023] [Indexed: 12/30/2023]
Abstract
OBJECTIVE The Suicidal Ideation Questionnaire (SIQ) and the Suicidal Ideation Questionnaire-Junior (SIQ-Jr) were designed to capture suicidal ideation in adolescents and are often used in clinical trials. Our aim was to identify and appraise the published literature with respect to the validity, reliability, responsiveness, and interpretability of the SIQ and SIQ-Jr. METHOD We conducted a systematic review following COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) guidelines to identify, appraise, and synthesize published literature on measurement properties and interpretability of the SIQ and SIQ-Jr. We searched MEDLINE, Embase, APA PsycINFO, CINAHL, Web of Science, and Scopus from inception to May 16, 2023, to identify sources relevant to our aim. RESULTS We identified 15 sources meeting our eligibility criteria. The body of literature did not meet COSMIN standards to make recommendations for use with regard to these measurement instruments. CONCLUSION Further research is needed, with a focus on content validity and structural validity, prior to recommending the SIQ and SIQ-Jr for use in clinical practice and in clinical trials. No specific grant funding was used for this review.

Paper II: thematic framework analysis of registry-based randomized controlled trials provided insights for designing trial ready registries. J Clin Epidemiol 2023; 159:330-343. [PMID: 37146660 DOI: 10.1016/j.jclinepi.2023.04.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 04/12/2023] [Accepted: 04/26/2023] [Indexed: 05/07/2023]
Abstract
OBJECTIVES Registry-based randomized controlled trials (RRCTs) are increasingly used, promising to address challenges associated with traditional randomized controlled trials. We identified strengths and limitations reported in planned and completed RRCTs to inform future RRCTs. STUDY DESIGN AND SETTING We conducted an environmental scan of literature discussing conceptual or methodological strengths and limitations of using registries for trial design and conduct (n = 12), followed by an analysis of RRCT protocols (n = 13) and reports (n = 77) identified from a scoping review. Using framework analysis, we developed and refined a conceptual framework of RRCT-specific strengths and limitations. We mapped and interpreted strengths and limitations discussed by authors of RRCT articles using framework codes and quantified the frequencies at which these were mentioned. RESULTS Our conceptual framework identified six main RRCT strengths and four main RRCT limitations. Considering implications for RRCT conduct and design, we formulated ten recommendations for registry designers, administrators, and trialists planning future RRCTs. CONCLUSION Consideration and application of empirically underpinned recommendations for future registry design and trial conduct may help trialists utilize registries and RRCTs to their full potential.

Paper I: Heterogeneous use of registry data for participant identification and primary outcome ascertainment is found in registry-based randomized controlled trials: A scoping review. J Clin Epidemiol 2023; 159:289-299. [PMID: 37146658 DOI: 10.1016/j.jclinepi.2023.04.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 03/20/2023] [Accepted: 04/26/2023] [Indexed: 05/07/2023]
Abstract
OBJECTIVES Registry-based randomized controlled trials (RRCTs) have potential to address limitations of traditional clinical trials. To describe their current use, information on planned and published RRCTs was identified and synthesized. STUDY DESIGN AND SETTING A scoping review of published RRCT protocols and reports was conducted. Articles published between 2010 and 2021 identified from electronic database searching, a recent review of RRCTs, and targeted searching for recent RRCT protocols (2018-2021) were screened. Data on trial data sources, types of primary outcomes, and how these primary outcomes were described, selected, and reported were extracted. RESULTS Ninety RRCT articles (77 reports; 13 protocols) were included. Forty nine (54%) used or planned to rely on registry data for their trial, 26 (29%) used both registry and additional data, and 15 (17%) used the registry solely for recruitment. Primary outcomes were routinely collected from the registry for 66 articles (73%). Only 28 articles (31%) described any methods to promote outcome data quality during or after data collection. Core outcome sets were not used in any of the trials. CONCLUSION With improvements in registry design, outcome selection, measurement, and reporting, future RRCTs may deliver on promises of efficient, high-quality trials that address clinically relevant questions.

How much is enough? Considering minimally important change in youth mental health outcomes. Lancet Psychiatry 2022; 9:992-998. [PMID: 36403601 DOI: 10.1016/s2215-0366(22)00338-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Revised: 08/19/2022] [Accepted: 09/16/2022] [Indexed: 11/19/2022]
Abstract
To make decisions in mental health care, service users, clinicians, and administrators need to make sense of research findings. Unfortunately, study results are often presented as raw questionnaire scores at different time points and regression coefficients, which are difficult to interpret with regards to their clinical meaning. Other commonly reported treatment outcome indicators in clinical trials or meta-analyses do not convey whether a given change score would make a noticeable difference to service users. There is an urgent need to improve the interpretability and relevance of outcome indicators in youth mental health (aged 12-24 years), in which shared decision making and person-centred care are cornerstones of an ongoing global transformation of care. In this Personal View, we make a case for considering minimally important change (MIC) as a meaningful, accessible, and user-centred outcome indicator. We discuss what the MIC represents, how it is calculated, and how it can be implemented in dialogues between clinician and researcher, and between youth and clinician. We outline how use of the MIC could enhance reporting in clinical trials, meta-analyses, clinical practice guidelines, and measurement-based care. Finally, we identify current methodological challenges around estimating the MIC and areas for future research. Efforts to select outcome domains and valid measurement instruments that resonate with youth, families, and clinicians have increased in the past 5 years. In this context, now is the time to define demarcations of changes in outcome scores that are clinically relevant, and meaningful to youth and families. Through the use of MIC, youth-centred outcome measurement, analysis, and reporting would support youth-centred therapeutic decision making.

Predictors, Moderators, and Mediators Associated With Treatment Outcome in Randomized Clinical Trials Among Adolescents With Depression: A Scoping Review. JAMA Netw Open 2022; 5:e2146331. [PMID: 35103789 PMCID: PMC8808324 DOI: 10.1001/jamanetworkopen.2021.46331] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Accepted: 12/08/2021] [Indexed: 12/26/2022] Open
Abstract
Importance The application of precision medicine principles for the treatment of depressive disorders in adolescents requires an examination of the variables associated with depression outcomes in randomized clinical trials (RCTs). Objective To describe predictors, moderators, and mediators associated with outcomes in RCTs for the treatment of depressive disorders in adolescents. Evidence Review A scoping review of RCTs for the treatment of depression in adolescents was conducted. Databases searched included MEDLINE, Embase, APA PsycInfo, and CINAHL. Included publications tested predictors, moderators, and/or mediators associated with depression symptom outcomes (eg, symptom reduction, response, remission) in RCTs pertaining to the treatment of adolescents, ages 13 to 17 years. Predictors were defined as variables that were associated with depression outcomes, independent of treatment group. Moderators were defined as baseline variables that were associated with differential outcomes between treatment groups. Mediators were defined by a formal mediation analysis. In duplicate, variables were extracted and coded with respect to analysis type (univariable or multivariable), statistical significance, direction of effect size, reporting of a priori hypotheses, and adjustment for multiple comparisons. Aggregated results were summarized by variable domain and RCT sample. Findings Eighty-one articles reporting on variables associated with outcomes across 33 RCTs were identified, including studies of biological (10 RCTs), psychosocial (18 RCTs), and combined (4 RCTs) treatments as well as a service delivery model (1 RCT). Fifty-three variable domains were tested as baseline predictors of depression outcome, 41 as moderators, 19 as postbaseline predictors, and 5 as mediators. Variable domains that were reported as significant in at least 3 RCTs included age, sex/gender, baseline depression severity, early response to treatment, sleep changes, parent-child conflict, overall psychopathology, suicidal ideation, hopelessness, functional impairment, attendance at therapy sessions, and history of trauma. Two publications reported a priori hypotheses and adjustment for multiple comparisons, both finding that baseline depression severity and family conflict were associated with poorer outcomes. Conclusions and Relevance This review identified commonly researched variables requiring more scrutiny as well as underresearched variables to inform future study designs. Further efforts to discover predictors, moderators, and mediators associated with treatment response have great potential to optimize care for adolescents with depression.

Forks in the road: Definitions of response, remission, recovery, and other dichotomized outcomes in randomized controlled trials for adolescent depression. A scoping review. Depress Anxiety 2021; 38:1152-1168. [PMID: 34312952 DOI: 10.1002/da.23200] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2020] [Revised: 06/18/2021] [Accepted: 06/24/2021] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND Definitions of dichotomous outcome terms, such as "response," "remission," and "recovery" are central to the design, interpretation, and clinical application of randomized controlled trials of adolescent depression interventions. Accordingly, this scoping review was conducted to document how these terms have been defined and justified in clinical trials. METHOD Bibliographic databases MEDLINE, Embase, APA PsycInfo, and CINAHL were searched from inception to February 2020 for randomized controlled trials evaluating treatments for adolescent depression. Ninety-eight trials were included for data extraction and analysis. RESULTS Assessment of outcome measurement instruments, metric strategies, methods of aggregation, and measurement timing, yielded 53 unique outcome definitions of "response" across 45 trials that assessed response, 47 unique definitions of "remission" in 29 trials that assessed remission, and 19 unique definitions of "recovery" across 11 trials that assessed recovery. A minority of trials (N = 35) provided a rationale for dichotomous outcomes definitions, often by citing other studies that used a similar definition (N = 11). No rationale included input from youth or families with lived experience. CONCLUSION Our review revealed that definitions of "response," "remission," "recovery," and related terms are highly variable, lack clear rationales, and are not informed by key stakeholder input. These limitations impair pooling of trial results and the incorporation of trial findings into pragmatic treatment decisions in clinical practice. Systematic approaches to establishing outcome definitions are needed to enhance the impact of trials examining adolescent depression treatment.

Abstract
BACKGROUND Current first-line treatments for paediatric depression demonstrate mild-to-moderate effectiveness. This has spurred a growing body of literature on lifestyle recommendations pertaining to nutrition, sleep and exercise for treating paediatric depression. AIMS Paediatric depression clinical practice guidelines (CPGs) were reviewed for quality and to catalogue recommendations on nutrition, sleep and exercise made by higher-quality CPGs. METHOD Searches were conducted in Medline, EMBASE, PsycINFO, Web of Science and CINAHL, and grey literature CPGs databases for relevant CPGs. Eligible CPGs with a minimum or high-quality level, as determined by the Appraisal of Guidelines for Research and Evaluation, Second Edition instrument, were included if they were (a) paediatric; (b) CPGs, practice parameter or consensus or expert committee recommendations; (c) for depression; (d) the latest version and (e) lifestyle recommendations for nutrition, sleep or exercise. Key information extracted included author(s), language, year of publication, country, the institutional body issuing the CPG, target disorder, age group, lifestyle recommendation and the methods used to determine CPG lifestyle recommendations. RESULTS Ten paediatric CPGs for depression with a minimum or high-quality level contained recommendations on nutrition, sleep or exercise. Lifestyle recommendations were predominately qualitative, with quantitative details only outlined in two CPGs for exercise. Most recommendations were brief general statements, with 50% lacking supporting evidence from the literature. CONCLUSIONS Interest in lifestyle interventions for treatment in child and youth depression is growing. However, current CPG lifestyle recommendations for nutrition, sleep or exercise are based on expert opinion rather than clinical trials.

Problem-solving training as an active ingredient of treatment for youth depression: a scoping review and exploratory meta-analysis. BMC Psychiatry 2021; 21:397. [PMID: 34425770 PMCID: PMC8383463 DOI: 10.1186/s12888-021-03260-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Accepted: 04/28/2021] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND Problem-solving training is a common ingredient of evidence-based therapies for youth depression and has shown effectiveness as a versatile stand-alone intervention in adults. This scoping review provided a first overview of the evidence supporting problem solving as a mechanism for treating depression in youth aged 14 to 24 years. METHODS Five bibliographic databases (APA PsycINFO, CINAHL, Embase, MEDLINE, Web of Science) and the grey literature were systematically searched for controlled trials of stand-alone problem-solving therapy; secondary analyses of trial data exploring problem-solving-related concepts as predictors, moderators, or mediators of treatment response within broader therapies; and clinical practice guidelines for youth depression. Following the scoping review, an exploratory meta-analysis examined the overall effectiveness of stand-alone problem-solving therapy. RESULTS Inclusion criteria were met by four randomized trials of problem-solving therapy (524 participants); four secondary analyses of problem-solving-related concepts as predictors, moderators, or mediators; and 23 practice guidelines. The only clinical trial rated as having a low risk of bias found problem-solving training helped youth solve personal problems but was not significantly more effective than the control at reducing emotional symptoms. An exploratory meta-analysis showed a small and non-significant effect on self-reported depression or emotional symptoms (Hedges' g = - 0.34; 95% CI: - 0.92 to 0.23) with high heterogeneity. Removing one study at high risk of bias led to a decrease in effect size and heterogeneity (g = - 0.08; 95% CI: - 0.26 to 0.10). A GRADE appraisal suggested a low overall quality of the evidence. Tentative evidence from secondary analyses suggested problem-solving training might enhance outcomes in cognitive-behavioural therapy and family therapy, but dedicated dismantling studies are needed to corroborate these findings. Clinical practice guidelines did not recommend problem-solving training as a stand-alone treatment for youth depression, but five mentioned it as a treatment ingredient. CONCLUSIONS On its own, problem-solving training may be beneficial for helping youth solve personal challenges, but it may not measurably reduce depressive symptoms. Youth experiencing elevated depressive symptoms may require more comprehensive psychotherapeutic support alongside problem-solving training. High-quality studies are needed to examine the effectiveness of problem-solving training as a stand-alone approach and as a treatment ingredient.

International consensus on a standard set of outcome measures for child and youth anxiety, depression, obsessive-compulsive disorder, and post-traumatic stress disorder. Lancet Psychiatry 2021; 8:76-86. [PMID: 33341172 DOI: 10.1016/s2215-0366(20)30356-4] [Citation(s) in RCA: 55] [Impact Index Per Article: 18.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2020] [Revised: 07/27/2020] [Accepted: 08/03/2020] [Indexed: 12/20/2022]
Abstract
A major barrier to improving care effectiveness for mental health is a lack of consensus on outcomes measurement. The International Consortium for Health Outcomes Measurement (ICHOM) has already developed a consensus-based standard set of outcomes for anxiety and depression in adults (including the Patient Health Questionnaire-9, the Generalised Anxiety Disorder 7-item Scale, and the WHO Disability Schedule). This Position Paper reports on recommendations specifically for anxiety, depression, obsessive-compulsive disorder, and post-traumatic stress disorder in children and young people aged between 6 and 24 years. An international ICHOM working group of 27 clinical, research, and lived experience experts formed a consensus through teleconferences, an exercise using an adapted Delphi technique (a method for reaching group consensus), and iterative anonymous voting, supported by sequential research inputs. A systematic scoping review identified 70 possible outcomes and 107 relevant measurement instruments. Measures were appraised for their feasibility in routine practice (ie, brevity, free availability, validation in children and young people, and language translation) and psychometric performance (ie, validity, reliability, and sensitivity to change). The final standard set recommends tracking symptoms, suicidal thoughts and behaviour, and functioning as a minimum through seven primarily patient-reported outcome measures: the Revised Children's Anxiety and Depression Scale, the Obsessive Compulsive Inventory for Children, the Children's Revised Impact of Events Scale, the Columbia Suicide Severity Rating Scale, the KIDSCREEN-10, the Children's Global Assessment Scale, and the Child Anxiety Life Interference Scale. The set's recommendations were validated through a feedback survey involving 487 participants across 45 countries. The set should be used alongside the anxiety and depression standard set for adults with clinicians selecting age-appropriate measures.

Abstract
Computer-assisted surgical devices, or "surgical robots," have recently been approved for general surgical use. The device allows the surgeon remote control of multi-articulated instrument arms with a three-dimensional view. Here we report the first known case of pancreatic resection with use of a computer-assisted, or robotic, surgical device. A 46-year old woman presented with back pain and a complex cystic mass in the tail of the pancreas. The daVinci surgical robot was used to remove the lesion en bloc with the tail of the pancreas and spleen. The patient did well and returned to full activity promptly. In summary, robotic technology may enhance advanced laparoscopic procedures. Pancreatic resection is feasible, and future experience will determine the true benefits of this technique.

Abstract
BACKGROUND A new type of computer-enhanced telemanipulator device for "robotic" laparoscopic surgery was recently approved. We prospectively evaluated the initial patients undergoing procedures with this new device at our institution. METHODS Patient demographics, operative indications, port placement, operative time, robot time, complications, and hospital stay were recorded. Follow-up evaluation was appropriate for the individual procedure. RESULTS Initially, 35 cases were managed. There were 22 anti-reflux procedures, 9 Heller myotomies, 1 pyloroplasty, 1 distal pancreatectomy with splenectomy, 1 esophagectomy with intrathoracic anastomosis, and 1 diagnostic laparoscopy. The operative times ranged from 88 to 458 min. The robot use times were between 16 and 185 min. There were no device-related complications. CONCLUSIONS Computer-enhanced robotic telesurgery is a safe and effective treatment method for a variety of diseases of the proximal gastrointestinal tract. Further study is needed to determine the benefits of this approach as compared with current technology.

Abstract
PURPOSE Our objective was to determine the efficacy of computer-assisted robotic laparoscopic Heller myotomy. METHODS A 76-year-old woman with a significant history of achalasia was evaluated for laparoscopic Heller myotomy. The daVinci surgical system was used throughout the procedure. RESULTS Computer assistance allowed scaling of hand motions from a range of 2:1 to 5:1. Successful dissection of the esophageal musculature was accomplished, and a Toupet-type fundoplication was performed. The patient was discharged from the hospital the day after surgery with five port incisions, each <1 cm. CONCLUSIONS Telemanipulator computer-assisted surgical devices may have applications in procedures that require advanced and finely tuned motions, such as Heller myotomy. The benefits of extra magnification and three-dimensional imaging can help prevent esophageal perforation and identify residual circular muscle fibers.

Nonoperative management of blunt splenic injury in adults 55 years and older: a twenty-year experience. Am Surg 2000; 66:636-40.

Abstract
The nonoperative management of splenic injury secondary to blunt trauma in older patients remains controversial. We have reviewed our experience from January 1978 to December 1997 with selective nonoperative management of blunt splenic injury in adults 55 years and older. Criteria for nonoperative management included hemodynamic stability with any transient hypotension corrected using less than 2,000 cm3 crystalloid infusion, a negative abdominal physical examination ruling out associated injuries, and a blood transfusion requirement of no more than 2 units attributable to the splenic injury. During the study period, 18 patients over age 55 with radiographic confirmation of a splenic injury met the above criteria for nonoperative management. Their mean age was 72 years (range 56-86), and 13 of the 18 were female (72%). The mean Injury Severity Score was 15 (range 4-29), with the mechanism of injury equally divided between automobile crashes (9) and falls (9). During a similar time period, 15 patients 55 years or older with splenic injury composed an operative group; these patients did not differ with respect to age (mean 68 years), sex (60% female), or mechanism of injury. CT scans of 8 patients managed nonoperatively were available and graded using the American Association for the Surgery of Trauma classification, with a mean score of 2.3 (range 2-3). Eight of the 18 nonsurgical patients received blood transfusions. None of the 18 patients who met the criteria for nonoperative management "failed" the protocol, and none were taken to the operating room for abdominal exploration. Two patients (11%) died of associated thoracic injuries after lengthy hospital stays, one at 10 days and one at 24 days. We conclude from our data that nonoperative management of blunt splenic injury in patients age 55 years and older is indicated provided they are hemodynamically stable, do not require significant blood transfusion, and have no other associated abdominal injuries.

Hypothermia-induced coagulopathy during hemorrhagic shock. Am Surg 2000; 66:348-54. [PMID: 10776871] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/16/2023]
Abstract
A porcine model of hemorrhagic shock was used to study the effect of hypothermia on hemodynamic, metabolic, and coagulation parameters. The model was designed to simulate the events of severe blunt injury with hemorrhage occurring initially, to a systolic blood pressure of 30 mm Hg, followed by simultaneous hemorrhage and crystalloid volume replacement, followed by cessation of hemorrhage and blood replacement. Half of the animals were rendered hypothermic by external application of ice, and half remained normothermic. There was seven pigs in each group. Two deaths occurred in each during the hemorrhage phase. The hypothermic pigs demonstrated larger reduction in cardiac output than normothermic pigs. Volume replacement in the normothermic group restored cardiac output to baseline values. In the hypothermic group, cardiac output remained depressed despite volume replacement. Prothrombin times and partial thromboplastin times showed significantly more prolongation in the hypothermic group. Furthermore, this was not corrected by replacement of shed blood in the hypothermic group, as was seen in the normothermic group. We conclude that when shock and hypothermia occur together, their deleterious effect on hemodynamic and coagulation parameters are additive. The effects of hypothermia persist despite the arrest of hemorrhage and volume replacement. Thus, it is necessary to aggressively address both shock and hypothermia when they occur simultaneously.

Abstract
BACKGROUND Previous studies have reported low conviction rates for drunk drivers injured in motor vehicle crashes and transported to the hospital. The purpose of this study was to evaluate this rate during a recent period and to investigate the variables that predict alcohol-related convictions for injured drunk drivers admitted to our hospital. METHODS A retrospective review of medical records from January 1991 through May 1997 identified 71 patients who were legally intoxicated drivers injured in motor vehicle crashes. Court records, police reports, and driving records were also obtained. RESULTS Overall, 51% of the drunk drivers were convicted of alcohol-related offenses and 32% escaped without any conviction. Blood alcohol level and a police officer's estimation of whether the driver had been drinking were significant predictors of an alcohol-related conviction. Age, Injury Severity Score, a police officer's estimation of injury, and the number of people or cars involved in the crash were not significantly associated with legal outcome. CONCLUSION Although this study shows an important increase in alcohol-related conviction rates, responsibility for further progress will depend on the medical community, law enforcement agencies, and the judicial system working together.
