A comparative evaluation of telehealth and direct assessment when screening for spasticity in residents of two long-term care facilities.

OBJECTIVE: To evaluate the performance of telehealth as a screening tool for spasticity compared to direct patient assessment in the long-term care setting. DESIGN: Cross-sectional, observational study. SETTING: Two long-term care facilities: a 140-bed veterans' home and a 44-bed state home for individuals with intellectual and developmental disabilities. SUBJECTS: Sixty-one adult residents of two long-term care facilities (aged 70.1 ± 16.2 years) were included in this analysis. Spasticity was identified in 43% of subjects (Modified Ashworth Scale rating mode = 2). Contributing diagnoses included traumatic brain injury, spinal cord injury, birth trauma, stroke, cerebral palsy, and multiple sclerosis. MAIN MEASURES: Movement disorders neurologists conducted in-person examinations to determine whether spasticity was present (reference standard) and also evaluated subjects with spasticity using the Modified Ashworth Scale. Telehealth screening examinations, facilitated by a bedside nurse, were conducted remotely by two teleneurologists using a three-question screening tool. Telehealth screening determinations of spasticity were compared to the reference standard determination to calculate sensitivity, specificity, and the area under the curve (AUC) in receiver operating characteristics. Teleneurologist agreement was evaluated using Cohen's kappa. RESULTS: Teleneurologist 1 had a specificity of 89% and sensitivity of 65% to identify the likely presence of spasticity (n = 61; AUC = 0.770). Teleneurologist 2 showed 100% specificity and 82% sensitivity (n = 16; AUC = 0.909). There was almost perfect agreement between the two examiners at 94% (kappa = 0.875, 95% CI: 0.640-1.000). CONCLUSION: Telehealth may provide a useful, efficient method of identifying residents of long-term care facilities that likely need referral for spasticity evaluation.

Physician tracking in sub-Saharan Africa: current initiatives and opportunities.

BACKGROUND: Physician tracking systems are critical for health workforce planning as well as for activities to ensure quality health care - such as physician regulation, education, and emergency response. However, information on current systems for physician tracking in sub-Saharan Africa is limited. The objective of this study is to provide information on the current state of physician tracking systems in the region, highlighting emerging themes and innovative practices. METHODS: This study included a review of the literature, an online search for physician licensing systems, and a document review of publicly available physician registration forms for sub-Saharan African countries. Primary data on physician tracking activities was collected as part of the Medical Education Partnership Initiative (MEPI) - through two rounds over two years of annual surveys to 13 medical schools in 12 sub-Saharan countries. Two innovations were identified during two MEPI school site visits in Uganda and Ghana. RESULTS: Out of twelve countries, nine had existing frameworks for physician tracking through licensing requirements. Most countries collected basic demographic information: name, address, date of birth, nationality/citizenship, and training institution. Practice information was less frequently collected. The most frequently collected practice fields were specialty/degree and current title/position. Location of employment and name and sector of current employer were less frequently collected. Many medical schools are taking steps to implement graduate tracking systems. We also highlight two innovative practices: mobile technology access to physician registries in Uganda and MDNet, a public-private partnership providing free mobile-to-mobile voice and text messages to all doctors registered with the Ghana Medical Association. CONCLUSION: While physician tracking systems vary widely between countries and a number of challenges remain, there appears to be increasing interest in developing these systems and many innovative developments in the area. Opportunities exist to expand these systems in a more coordinated manner that will ultimately lead to better workforce planning, implementation of the workforce, and better health.

Using an electronic prescribing system to ensure accurate medication lists in a large multidisciplinary medical group.

BACKGROUND: Although medication safety has largely focused on reducing medication errors in hospitals, the scope of adverse drug events in the outpatient setting is immense. A fundamental problem occurs when a clinician lacks immediate access to an accurate list of the medications that a patient is taking. Since 2001, PeaceHealth Medical Group (PHMG), a multispecialty physician group, has been using an electronic prescribing system that includes medication-interaction warnings and allergy checks. Yet, most practitioners recognized the remaining potential for error, especially because there was no assurance regarding the accuracy of information on the electronic medical record (EMR)-generated medication list. PeaceHealth developed and implemented a standardized approach to (1) review and reconcile the medication list for every patient at each office visit and (2) report on the results obtained within the PHMG clinics. METHODS: In 2005, PeaceHealth established the ambulatory medication reconciliation project to develop a reliable, efficient process for maintaining accurate patient medication lists. Each of PeaceHealth's five regions created a medication reconciliation task force to redesign its clinical practice, incorporating the systemwide aims and agreed-on key process components for every ambulatory visit. RESULTS: Implementation of the medication reconciliation process at the PHMG clinics resulted in a substantial increase in the number of accurate medication lists, with fewer discrepancies between what the patient is actually taking and what is recorded in the EMR. DISCUSSION: The PeaceHealth focus on patient safety, and particularly the reduction of medication errors, has involved a standardized approach for reviewing and reconciling medication lists for every patient visiting a physician office. The standardized processes can be replicated at other ambulatory clinics-whether or not electronic tools are available.

Recurrent refrains in a patient with multiple sclerosis: Earworms or musical hallucinations?

Musical hallucinations are recognized in certain neurological and psychiatric conditions and can be caused by focal brain disease (Evers and Ellger, 2004). However, the occurrence of primary musical hallucinations in multiple sclerosis (MS) has not been reported previously. We report a case of a 54 year old woman with progressive, relapsing MS who has continuous, unremitting, complex auditory phenomenon for an extended period of time. We believe that MS lesions rather than medications are the cause for this disturbing symptom and we present a brief review of the literature regarding the current views on the neural substrates of musical perception and cognition.

Experience of head and neck theatre staff and attitudes to human factors using an aviation-based analysis and classification system--a pilot survey.

The role that human factors have in contributing to air crashes is well known and is included as an essential part of training. Awareness of human factors in surgery is increasingly being recognised but surprisingly few papers have come from head and neck specialties. We circulated a questionnaire on human factors based on an aviation model to 140 head and neck medical and ancillary staff who work in operating theatres in 3 large UK hospitals. Most positive responses were found in the consultant group followed by trainee doctors and support staff. A significant difference was found in the subcategories of Unsafe Supervision (p=0.002) and Preconditions to Unsafe Acts (p=0.001). This work will help to identify multi-system deficiencies that can be corrected, and highlights aspects that may yield the greatest reduction in surgical errors.

Strengthening research governance for sustainable research: experiences from three Zimbabwean universities.

A robust research system requires a robust governance framework. As part of the Medical Education Partnership Initiative, three Zimbabwean universities partnered with two U.S. universities in a project to strengthen research governance in the Zimbabwean universities. The project aimed at (1) developing research policies, (2) strengthening central research management offices, (3) developing a research administration curriculum, and (4) enhancing awareness about the role and relevance of research administration in other universities and research institutions in Zimbabwe. Through the efforts of the partners, a generic research policy was developed and successfully adapted by the institutions. A curriculum was drafted, and module development experts are helping to finalize the curriculum to meet university requirements for accreditation of training research administrators. The Association of Research Managers of Zimbabwe was established to promote information sharing and professionalize research administration. The consortium approach enabled rapid and smooth development and adoption of research policies in the institutions. It also helped researchers and managers accept research administration as an essential structure and function. The experiences and lessons learned are reported here to benefit other institutions and consortia.

Implementation trial of the basic life support termination of resuscitation rule: reducing the transport of futile out-of-hospital cardiac arrests.

BACKGROUND: The basic life support (BLS) termination of resuscitation (TOR) rule recommends transport and continued resuscitation when cardiac arrest is witnessed by EMT-Ds, or there is a return of spontaneous circulation, or a shock is given, and prior studies have suggested the transport rate should fall to 37%. METHODS AND RESULTS: This real-time prospective multi-center implementation trial evaluated the BLS TOR rule for compliance, transport rate and provider and physician comfort. Both provider and physician noted their decision-making rationale and ranked their comfort on a 5-point Likert scale. Functional survival was measured at discharge. Of 2421 cardiac arrests, 953 patients were eligible for the rule, which was applied correctly for 755 patients (79%) of which 388 were terminated. 565 patients were transported resulting in a reduction of the transport rate from 100% (historical control) to 59% (p<0.001). The BLS TOR rule was not followed in 198 eligible patients (21%) and they were all transported despite meeting the criteria to terminate. Providers cited 241 reasons for non-compliance: family distress, short transport time interval, younger age and public venue. All 198 transported patients, non-compliant with the rule, died. Both providers and physicians were comfortable with using the rule to guide TOR (median [IQR] of 5 [4,5]; p<0.001). CONCLUSIONS: This implementation trial confirmed the accuracy of the BLS TOR rule in identifying futile out-of-hospital cardiac arrest (OHCA) resuscitations, significantly reduced the transport rate of futile OHCA and most providers and physicians were comfortable following the rule's recommendations.

Medical student in global health-just one part of a larger commitment.

Across U.S. medical schools, the interest in global health is rapidly growing. Medical schools are challenged by the sheer numbers of students requesting or independently arranging educational experiences in the developing world. The logistics, legalities, and ethical issues have led to the development of a variety of models that enable student participation in safe and educationally enriching experiences. A major challenge is providing for the educational needs of the students within the medical and cultural environment of the host country without being culturally insensitive or disruptive. While not all of these programs will be successful, some models, like those described in this issue of Academic Medicine, are instructive. The educational experience of the U.S. medical students should not be the only measured outcome however. In exchange for the educational opportunities provided to medical students, U.S. medical schools should commit to sustained involvement in these countries, ensuring a meaningful experience for students and value added to the host countries.

Efficacy of the ANAM General Neuropsychological Screening Battery (ANAM GNS) for detecting neurocognitive impairment in a mixed clinical sample.

The Automated Neuropsychological Assessment Metrics (ANAM) is a computerized neuropsychological assessment battery that has demonstrated utility in a variety of clinical populations including multiple sclerosis, systemic lupus erythematosus, Parkinson's disease, acquired brain injury, migraine headaches, and Alzheimer's disease. This study utilized selected tests from the ANAM General Neuropsychological Screening Battery (ANAM GNS), a newly defined subset of tests from the broader ANAM library designed for general clinical assessment of cognition. ANAM GNS is an expansion of the ANAM Core battery which has been utilized in a military setting. The efficacy of the ANAM GNS was explored in a mixed clinical sample relative to well-established, traditional neuropsychological measure, the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). It was hypothesized that scores from the ANAM GNS would accurately predict participants as either impaired (n = 30) or normal (n = 113). Participants were grouped a priori based on RBANS Total Index scores with impairment defined as scores ≤ 15th percentile. Logistic regression analysis was conducted to evaluate the classification accuracy of the ANAM GNS. The predictor variables were the Throughput scores from seven selected ANAM GNS subtests. The full model significantly predicted impairment status, sensitivity was 81% and specificity was 89.1%. Overall classification rate was 87.9% and the Odds Ratio for the overall model was 34.65. Positive predictive value was 56.7% and negative predictive value was 96.4%. This study represents the first clinical data on the ANAM GNS, and documents that it has good concurrent and predictive validity with a well-established neuropsychological measure.

Clinical phase 1 testing of the safety and immunogenicity of an epitope-based DNA vaccine in human immunodeficiency virus type 1-infected subjects receiving highly active antiretroviral therapy.

A DNA vaccine encoding sequence-conserved human immunodeficiency virus type 1 (HIV-1)-derived cytotoxic T-lymphocyte (CTL) epitopes from multiple HIV-1 gene products (designated EP HIV-1090) was evaluated in a placebo-controlled, dose escalation phase 1 clinical trial of HIV-1-infected subjects receiving potent combination antiretroviral therapy. Patients received four intramuscular immunizations with EP HIV-1090 over a 4-month period at one of four doses (0.5, 1.0, 2.0, or 4.0 mg) or received a placebo. The vaccine was determined to be safe and well tolerated at all doses tested. CTL responses were measured from cryopreserved peripheral blood mononuclear cells using gamma interferon enzyme-linked immunospot assays, with and without in vitro peptide stimulation (IVS). Responses to one or more vaccine epitopes were detected throughout the course of vaccination in 37.5% (12/32) and 47% (15/32) of vaccine recipients measured without and with IVS, respectively, indicating possible vaccine-induced priming of epitope-specific T cells. However, differences in rates of response to HIV-1 epitopes between vaccine and placebo recipients did not achieve statistical significance. The HIV-1 epitope-specific CTL responses measured in the peripheral blood after vaccination were often low level and short-lived, and therefore, alternative immunization schedules, routes of delivery, or vaccine formulations may be required to increase vaccine potency.

Human exposure following Mycobacterium tuberculosis infection of multiple animal species in a Metropolitan Zoo.

From 1997 to 2000, Mycobacterium tuberculosis was diagnosed in two Asian elephants (Elephas maximus), three Rocky Mountain goats (Oreamnos americanus), and one black rhinoceros (Diceros bicornis) in the Los Angeles Zoo. DNA fingerprint patterns suggested recent transmission. An investigation found no active cases of tuberculosis in humans; however, tuberculin skin-test conversions in humans were associated with training elephants and attending an elephant necropsy.
