Rapid Learning of Adverse Medical Event Disclosure and Apology. - Journal of patient safety
Despite published recommended best practices for full disclosure and apology to patients and families after adverse medical events, actual practice can be inadequate. The use of "cognitive aids" to help practitioners manage complex critical events has been successful in a variety of fields and healthcare. We wished to extend this concept to disclosure and apology events. The aim of this study was to test if a brief opportunity to review a best practice guideline for disclosure and apology would improve communication performance.Thirty pairs of experienced obstetricians and labor nurses participated in a 3-part exercise with mixed-realism simulation. The first part used a standardized actor patient to meet the obstetrical team. The second part used a high-fidelity simulation leading to an adverse medical event (retained sponge), and the third part used standardized actors, patient, and husband, who systematically move through stages of grief response. The participants were randomized into 2 groups, one was provided with a cognitive aid in the form of a best practice guideline for disclosure and apology and the other was only given time to plan. Four blinded raters working in pairs scored subjects on a 7-point scale using a previously developed assessment instrument modified for this study.Pooled ratings of the disclosure and apology discussion for the intervention group (n = 167, mean = 4.9, SD = 0.92) were higher than those from the control group (n = 167, mean = 4.3, SD = 1.21) (P <0.0001). One specific element was rated higher for the intervention group than the control group; posture toward the patient (n = 27, mean = 5.1, SD = 0.82 versus n = 28, mean = 4.3, SD = 1.33) (P = 0.020). The elements of dealing with anger, dealing with depression, dealing with denial, bargaining, and acceptance were not different.Experienced practitioners performed better in a simulated disclosure and apology conversation after reviewing a cognitive aid in the form of a best practice guideline than a control group that was only given time to prepare.
Evaluation of computer-based medical histories taken by patients at home. - Journal of the American Medical Informatics Association : JAMIA
The authors developed a computer-based general medical history to be taken by patients in their homes over the internet before their first visit with their primary care doctor, and asked six doctors and their participating patients to assess this history and its effect on their subsequent visit. Forty patients began the history; 32 completed the history and post-history assessment questionnaire and were for the most part positive in their assessment; and 23 continued on to complete their post-visit assessment questionnaire and were for the most part positive about the helpfulness of the history and its summary at the time of their visit with the doctor. The doctors in turn strongly favored the immediate, routine use of two modules of the history--the family and social histories--for all their new patients. The doctors suggested further that the summaries of the other modules of the history be revised and shortened to make it easier for them to focus on clinical issues in the order of their preference.
Electronic problem-solving treatment: description and pilot study of an interactive media treatment for depression. - JMIR research protocols
Computer-automated depression interventions rely heavily on users reading text to receive the intervention. However, text-delivered interventions place a burden on persons with depression and convey only verbal content.The primary aim of this project was to develop a computer-automated treatment for depression that is delivered via interactive media technology. By using branching video and audio, the program simulates the experience of being in therapy with a master clinician who provides six sessions of problem-solving therapy. A secondary objective was to conduct a pilot study of the program's usability, acceptability, and credibility, and to obtain an initial estimate of its efficacy.The program was produced in a professional multimedia production facility and incorporates video, audio, graphics, animation, and text. Failure analyses of patient data are conducted across sessions and across problems to identify ways to help the user improve his or her problem solving. A pilot study was conducted with persons who had minor depression. An experimental group (n = 7) used the program while a waitlist control group (n = 7) was provided with no treatment for 6 weeks.All of the experimental group participants completed the trial, whereas 1 from the control was lost to follow-up. Experimental group participants rated the program high on usability, acceptability, and credibility. The study was not powered to detect clinical improvement, although these pilot data are encouraging.Although the study was not powered to detect treatment effects, participants did find the program highly usable, acceptable, and credible. This suggests that the highly interactive and immersive nature of the program is beneficial. Further clinical trials are warranted.ClinicalTrials.gov NCT00906581; http://clinicaltrials.gov/ct2/show/NCT00906581 (Archived by WebCite at http://www.webcitation.org/6A5Ni5HUp).
Workplace telecommunications technology to identify mental health disorders and facilitate self-help or professional referrals. - American journal of health promotion : AJHP
Test the feasibility and impact of an automated workplace mental health assessment and intervention.Efficacy was evaluated in a randomized control trial comparing employees who received screening and intervention with those who received only screening.Workplace.463 volunteers from Boston Medical Center, Boston University, and EMC and other employed adults, among whom 164 were randomized to the intervention (N  =  87) and control (N  =  77) groups.The system administers a panel of telephonic assessment instruments followed by tailored information, education, and referrals.The Work Limitation Questionnaire, the Medical Outcomes Questionnaire Short Form-12, the Patient Health Questionnaire-9, question 10 from the Patient Health Questionnaire to measure functional impairment, and the Perceived Stress Scale-4 and questions written by study psychiatrists to measure emotional distress and social support respectively. The WHO-Five Well-being Index was administered to measure overall well-being.Independent sample t-tests and χ(2) tests as well as mean change were used to compare the data.No significant differences on 16 of the 20 comparisons at 3- and 6-month time points. The intervention group showed a significant improvement in depression (p ≤ .05) at 3 months and on two Work Limitation Questionnaire subscales, the Mental-Interpersonal Scale (p ≤ .05) and the Time and Scheduling Scale (p ≤ .05), at 3 and 6 months respectively with a suggestive improvement in mental health at 6 months (p ≤ .10).This is a potentially fruitful area for research with important implications for workplace behavioral interventions.
Test-retest reliability in a computer-based medical history. - Journal of the American Medical Informatics Association : JAMIA
The authors developed a computer-based medical history for patients to take in their homes via the internet. The history consists of 232 'primary' questions asked of all patients, together with more than 6000 questions, explanations, and suggestions that are available for presentation as determined by a patient's responses. The purpose of this research was to measure the test-retest reliability of the 215 primary questions that have preformatted, mutually exclusive responses of 'Yes,' 'No,' 'Uncertain (Don't know, Maybe),' 'Don't understand,' and 'I'd rather not answer.' From randomly selected patients of doctors affiliated with Beth Israel Deaconess Medical Center in Boston, 48 patients took the history twice with intervals between sessions ranging from 1 to 35 days (mean 7 days; median 5 days). High levels of test-retest reliability were found for most of the questions, but as a result of this study the authors revised five questions. They recommend that structured medical history questions that will be asked of many patients be measured for test-retest reliability before they are put into widespread clinical practice.
A roadmap to computer-based psychotherapy in the United States. - Harvard review of psychiatry
Computers can be used to deliver self-guided interventions and to provide access to live therapists at remote locations. These treatment modalities could help overcome barriers to treatment, including cost, availability of therapists, logistics of scheduling and traveling to appointments, stigma, and lack of therapist training in evidence-based treatments (EBTs). EBTs could be delivered at any time in any place to individuals who might otherwise not have access to them, improving public mental health across the United States. In order to fully exploit the opportunities to use computers for mental health care delivery, however, advances need to be made in four domains: (1) research, (2) training, (3) policy, and (4) industry. This article discusses specific challenges (and some possible solutions) to implementing computer-based distance therapy and self-guided treatments in the United States. It lays out both a roadmap and, in each of the four domains, the milestones that need to be met to reach the goal of making EBTs for behavioral health problems available to all Americans.
Terrorism, trauma, and mass casualty triage: how might we solve the latest mind-body problem? - Biosecurity and bioterrorism : biodefense strategy, practice, and science
The global war on terrorism has led to increased concern about the ability of the U.S. healthcare system to respond to casualties from a chemical, biological, or radiological agent attack. Relatively little attention, however, has focused on the potential, in the immediate aftermath of such an attack, for large numbers of casualties presenting to triage points with acute health anxiety and idiopathic physical symptoms. This sort of "mass idiopathic illness" is not a certain outcome of chemical, biological, or radiological attack. However, in the event that this phenomenon occurs, it could result in surges in demand for medical evaluations that may disrupt triage systems and endanger lives. Conversely, if continuous primary care is not available for such patients after initial triage, many may suffer with unrecognized physical and emotional injuries and illness. This report is the result of an expert planning initiative seeking to facilitate triage protocols that will address the possibility of mass idiopathic illness and bolster healthcare system surge capacity. The report reviews key triage assumptions and gaps in knowledge and offers a four-stage triage model for further discussion and research. Optimal triage approaches offer flexibility and should be based on empirical studies, critical incident modeling, lessons from simulation exercises, and case studies. In addition to staging, the proposed triage and longitudinal care model relies on early recognition of symptoms, development of a registry, and use of non-physician care management to facilitate later longitudinal followup and collaboration between primary care and psychiatry for the significant minority of patients who develop persistent idiopathic symptoms associated with reduced functional status.
Design and development of a mental health assessment and intervention system. - Journal of medical systems
Mental health disorders are the leading cause of disability and functional impairment in the United States (1 in 5). The negative effect of mental health disorders is felt both in the personal and public lives of the affected individuals, particularly in the workplace where it adversely impacts productivity. Only a small fraction of the affected people in the work force seeks help. The cost to employers and the economy of these untreated individuals is staggering. Some employers have tried to address employees' emotional well-being by establishing Employee Assistance Programs. Yet, even these programs do not sufficiently address existing barriers to the detection and treatment of mental health disorders in the workplace. This paper describes the design of an automated workplace program that uses an Interactive, computer-assisted telephonic system (Interactive Voice Response or IVR) to assess workers for a variety of mental health disorders and subsequently refers untreated and inadequately treated workers to appropriate treatment settings.
Psychosomatic medicine and biodefense preparedness--a new role for the American Psychosomatic Society. - Psychosomatic medicine
Biodefense preparations in the United States have focused mostly on improving biosurveillance and hospital surge capacity in the event of an outbreak or a weapons of mass destruction (WMD) event. However, what if an invisible bioweapon or dirty bomb was released in a major population center, or if avian flu took hold with sustained human to human transmission? Suddenly, we need to combine efforts from psychosomatic medicine and general medicine with public health practice to triage nonexposed patients with somatic symptoms from those with medical sequelae resulting from hazardous exposures. This would better enable the limited acute care resources to be directed to those most in need of urgent medical care. Furthermore, psychosomatic medicine experts are potentially important players in biodefense planning related to risk communication and health education strategies in a WMD scenario or outbreak in which individuals must make informed choices about their need for immediate medical attention.
Deviation from the mobile proton model in amino-modified peptides: implications for multiple reaction monitoring analysis of peptides. - Rapid communications in mass spectrometry : RCM
The study of peptide fragmentation is important to the understanding of chemical processes occurring in the gas phase and the more practical concern of peptide identification for proteomic analysis. Using the mobile proton model as a framework, we explore the effect of amino-group modifications on peptide fragmentation. Three aldehydes are used to transform the peptides' primary amino groups into either a dimethylamino or a heterocyclic structure (five- or six-membered). The observed fragmentation patterns deviate strongly from those observed for the analogous underivatised peptides. In particular, the a1 ion is the base peak in most tandem mass spectra of the derivatised peptides. The a1 ion intensity depends strongly on the N-terminal amino acid, with tyrosine and phenylalanine having the strongest enhancement. Despite the change in fragmentation patterns of the derivatised peptides, they still provide high-quality tandem mass spectra that, in many cases, are more amenable to database searching than the spectra of underivatised peptides. In addition, the reliable presence of the a1 ion facilitates rapid quantitative measurements using the multiple reaction monitoring approach.Copyright 2006 John Wiley & Sons, Ltd.
