Limited value of programmed electrical stimulation from multiple right ventricular pacing sites in clinically sustained ventricular fibrillation or ventricular tachycardia associated with coronary artery disease.

One-hundred and fifty patients with coronary artery disease and a documented history of sustained ventricular tachyarrhythmias were studied to determine if programmed electrical stimulation (PES) from a second right ventricular (RV) pacing site optimizes the induction of such sustained arrhythmias. The first PES test was performed from 2 RV pacing sites (apex and outflow tract or septum) using the apex first in each patient. All patients underwent a second PES within 6 to 24 hours of the first; both studies used up to 4 ventricular extrastimuli, in the absence of antiarrhythmic treatment. The second PES was performed from a single RV apical site using a pacing catheter retained from the first study. During the first day's study, 74 patients (49%) had sustained ventricular tachycardia induced from the RV apex. Only 11 of the remaining 76 patients (7% of the total group) were inducible exclusively from a second RV pacing location during the first day's testing. Seven of these 11 patients, as well as 15 additional patients who did not have ventricular tachycardia induced from either site on the first day's study, were inducible from the RV apex during the second drug-free study. Among patients with sustained ventricular tachyarrhythmias, limiting PES to a single RV site, with the option of performing a second study in those who are initially noninducible is more effective in inducing sustained ventricular tachyarrhythmias than is PES performed from 2 RV pacing sites.

The National Access to Antiretroviral Program for PHA (NAPHA) in Thailand.

To describe the development, components, initial results and lessons learned from Thailand's National Access to Antiretroviral Program for People living with HIV/AIDS (NAPHA), a historical review was conducted and program monitoring was analyzed. The national antiretroviral therapy program at different levels of the public health system was implemented with all major program components; ARV protocol development, health care professional training, drug supply chain management, laboratory network formation, monitoring and evaluation, and multi-sector and PHA involvement since 2001, which was based on elements of research, pilot projects, training, national guideline development, experiences and policy making. A national monitoring system was developed to monitor the progress of the program. From February 2001 to December 2004, the monitoring reports received from implementing hospitals showed that 58,133 cases had received antiretroviral therapy (ART), and 85% (49,477) of them were continuing to take ARV drugs. In conclusion, the NAPHA was implemented nationwide with comprehensive systems. The reports indicate achievement of expansion of the ART program. Lessons learned from the program initiation and scaling up show local leadership, comprehensive training, adherence, and coordination are essential to program effectiveness and sustainability.

Simultaneous appearance of endocardial late potentials and ability to induce sustained ventricular tachycardia after procainamide administration.

We describe a patient in whom procainamide induced the appearance of late potentials during intraoperative sinus rhythm electrogram mapping. Only nonsustained ventricular tachycardia (VT) could be induced while off all antiarrhythmic drugs. After administration of the procainamide, programmed stimulation induced sustained VT coincident with the appearance of late potentials during sinus rhythm. The late potential was recorded from the same site, during normal sinus rhythm, where mid to late diastolic activation during VT was recorded, and where cryotermination occurred during cryomapping. We hypothesize that procainamide slowed conduction, manifested as prolongation or appearance of late potentials in sinus rhythm, and facilitated induction of sustained reentrant ventricular tachycardia.

Effectiveness of employee health improvement programs.

Evidence of health effects, cost-effectiveness and cost-benefit of smoking cessation, hypertension control, physical fitness and weight management programs are reviewed. For hypertension control programs, health-effectiveness has been established both in community and worksite settings. Smoking cessation programs in clinical settings achieve six to 12-month abstinence of usually 15% to 30%, but occasionally 40% to 60%. Smoking cessation groups are probably cost-beneficial and, assuming average program costs and sustained quit rates, should be able to successfully compete for employer investment dollars with respect to return on investment. One study has reported a cost savings attributable to a corporate fitness program but problems of study design and assumption involved in generating cost estimates render the conclusions somewhat speculative. Credible data regarding cost-effectiveness and cost-benefit of weight management programs in clinical or worksite settings are not yet available.

OMB estimates indicate that 900,000 children will lose health insurance due to reductions in federal SCHIP funding.

Despite the success of the State Children's Health Insurance Program (SCHIP) in reducing the ranks of uninsured children, the program now faces significant financing challenges. Analysis based on a model developed by the Centers for Medicare and Medicaid Services indicates that by 2007, 20 states will have insufficient federal funding to sustain their current programs, with the first states affected in 2004. As a result, the Office of Management and Budget projected last year that SCHIP enrollment will fall by 900,000 children between 2003 and 2007. The funding shortfalls are the result of several factors. Federal SCHIP funding fell by 26 percent--by more than dollar 1 billion-in each of fiscal years 2002, 2003, and 2004; dollar 1.2 billion in SCHIP funds has already expired and reverted to the Treasury at the end of fiscal year 2002, and another dollar 1.5 billion will expire at the end of 2003. The SCHIP program also has a redistribution system with targeting and timing problems. However, proposed Congressional legislation restoring federal funding, extending the dollar 2.7 billion in expiring funds, and targeting the funds to the states that most need them could avert most, if not all, of the projected enrollment decline. On the other hand, the Bush administration proposed to extend the expiring funds but does not target them to needy states; the proposal will do little to reduce the magnitude of the decline.

Strengthening the public health workforce: three CDC programs that prepare managers and leaders for the challenges of the 21st century.

To address the need for management development in public health, the Centers for Disease Control and Prevention (CDC) established three independent workforce development initiatives aimed primarily at strengthening management and leadership capacity: the Sustainable Management Development Program, the Management Academy for Public Health, and the CDC Leadership and Management Institute. Though independently designed and implemented, the programs share similar guiding principles in their approach to management development: interactive (adult) learning, management tools that reinforce evidence-based decision making, individual feedback, continuous improvement of the learning process, posttraining support for networking and life-long learning, and teamwork. This article will discuss important lessons learned regarding best practices in management and leadership development.

The effects of school gardens on students and schools: conceptualization and considerations for maximizing healthy development.

There are thousands of school gardens in the United States, and there is anecdotal evidence that school garden programs can enhance students' learning in academic, social, and health-related domains. There has been little rigorous research, however, on the effects of school gardens or on the factors that promote the sustainability of these programs. This review draws on ecological theory to conceptualize school gardens as systemic interventions with the potential for promoting the health and well-being of individual students in multiple interdependent domains and for strengthening the school environment as a setting for positive youth development. This review (a) summarizes the small literature regarding the impact of school garden curricula on student or school functioning, (b) provides a conceptual framework to guide future inquiry, (c) discusses implications of this conceptualization for practice, and (d) suggests further research needed to better inform practice.

National community health worker programs: how can they be strengthened?

This article is based on a collaborative research study of policy and practice in national community health worker (CHW) programs in developing countries. The study involved a review of the relevant literature, case studies in Botswana, Colombia and Sri Lanka, and an international workshop where the future of such programs was discussed. The findings of this research are discussed under four headings: unrealistic expectations, poor initial planning, problems of sustainability, and the difficulties of maintaining quality. It is clear that existing national community health worker programs have suffered from conceptual and implementation problems. However, given the interest and political will, governments can address these problems by adopting more flexible approaches within their CHW programs, by planning for them within the context of all health sector activities rather than as a separate activity, and by immediately addressing weaknesses in task allocation, training and supervision. CHWs represent an important health resource, whose potential in extending coverage and providing a reasonable level of care to otherwise underserved populations must be fully tapped.

Improving influenza vaccination rates for high-risk inpatients.

PURPOSE: In 1987, the Minneapolis Veterans Affairs Medical Center implemented an ongoing, multifaceted influenza vaccination program that targeted all high-risk outpatients followed at the medical center. While the program achieved and sustained vaccination rates of 60% or more for high-risk outpatients, vaccination rates for high-risk inpatients continued to be 25% or less. Beginning with the 1989-1990 immunization season, the "flu shot" program was extended to include all high-risk inpatients. Both the outpatient and inpatient components of the Minneapolis Flu Shot Program emphasized administrative and organizational elements. The program's goal was to achieve vaccination rates of at least 60% for both high-risk outpatients and inpatients. This study assesses the effectiveness of the inpatient program among elderly patients hospitalized on the medical service during the immunization season. PATIENTS AND METHODS: To estimate patient risk characteristics and vaccination rates, 50% of elderly patients who were discharged from the medical service during the immunization season were surveyed using a validated postcard questionnaire. Their responses were compared with the responses of elderly patients to the annual outpatient survey conducted to assess the "flu shot" program. RESULTS: Overall, 78.6% of elderly respondents discharged from the medical service during the immunization season were vaccinated. Vaccination rates within various high-risk subgroups all exceeded 70%. None of these vaccination rates for inpatient groups differed significantly from the rates for corresponding outpatients. CONCLUSION: An outpatient "flu shot" program that emphasizes administrative and organizational elements can be successfully expanded to high-risk inpatients. The vaccination rates attained with such a program may not only achieve but exceed the national health objective for influenza vaccination.

An interactive perspective of health education for the tropical disease control: the schistosomiasis case.

Some municipalities in Brazil have been requesting orientation for the implementation of health education programs related to the control of schistosomiasis. This demand was based on experiences in the development of health education researches, strategies and materials for school-age children, involving the communities and secretaries of health and education. Motivated by this request and the recently implemented plan of health services (Unified Health System-Sistema Unico de Saúde-SUS) that gives autonomy to the municipalities to utilize health resources and services in Brazil, this paper presents an interactive perspective of planning health education research and programs. The purpose of this perspective is to stimulate a reflection on the needs and actions of institutions and people involved in health education research and/or programs to obtain sustainability, commitment and effectiveness--not only in the control of schistosomiasis, but also in the improvement of environmental conditions, quality of life and personal health. This perspective comprises interaction among three levels related to health education programs: the decision level, the executive level and the beneficiary level. The needs and lines of action at each of these levels are discussed, as well as the ways in which they can interact with each other. This proposal may lead to useful interactive ways of planing, organizing, executing and evaluating health education research and/or program, not only towards the prevention and control of the disease at stake, but also to promote health in general.

NGO-promoted women's credit program, immunization coverage, and child mortality in rural Bangladesh.

A growing number of non-governmental organizations (NGOs) are adopting the collateral-free credit programs by anchoring them with their social development programs aimed at improved program effectiveness and sustainability. Drawing upon a sample of 3,564 targeted poor households covered by five small NGOs in rural Bangladesh, this study finds that the NGO credit-members as well as those who reside in the NGO program area are higher adopters of child immunization than those in the non-program area. Similarly, the study found that infant and child mortality is lower among the NGO credit members than among the non-members and that under five-year deaths of children progressively decline with the increase in the doses of vaccines. Implications of these findings are discussed in the study.

Approaches to antiretroviral therapy in China.

China has recognized the threat of HIV to its population and responded with a national antiretroviral treatment (ART) program. However, high ART failure rates and the spread of resistance within populations are important realities to consider when developing and managing ART programs in China and worldwide. Concepts which will define treatment success and local and national programmatic goals are 1) access to ART, 2) durability of ART at the patient level, 3) scalability of treatment modalities, and the 4) sustainability of the program at the community or national level. In the face of limited resources, China must also consider when to start ARV therapy, which agents to use, when to switch them, and how to treat highly experienced patients with drug resistance. The optimal ARV regimen to start with is changing frequently with the introduction of new agents and the presentation of new data. Currently, a regimen including tenofovir, emtricitabine or lamivudine and a nonnucleoside reverse transcriptase inhibitor appears to have optimal characteristics to treat HIV/AIDS in China. However, critical to all of these choices is the evaluation of programs implemented to insure wide scale success. China has wisely begun this process of evaluating the performance of local programs through systematic monitoring and evaluation of treatment outcomes. This will allow regimens and programs that work to be expanded, and programs with high failure rates to be eliminated. In the end, evidence based data supporting treatment strategies will allow China to successfully confront its AIDS epidemic early and prevent its tragic consequences.

Falls and consequent injuries in hospitalized patients: effects of an interdisciplinary falls prevention program.

BACKGROUND: Patient falls in hospitals are common and may lead to negative outcomes such as injuries, prolonged hospitalization and legal liability. Consequently, various hospital falls prevention programs have been implemented in the last decades. However, most of the programs had no sustained effects on falls reduction over extended periods of time. METHODS: This study used a serial survey design to examine in-patient fall rates and consequent injuries before and after the implementation of an interdisciplinary falls prevention program (IFP) in a 300-bed urban public hospital. The population under study included adult patients, hospitalized in the departments of internal medicine, geriatrics, and surgery. Administrative patient data and fall incident report data from 1999 to 2003 were examined and summarized using frequencies, proportions, means and standard deviations and were analyzed accordingly. RESULTS: A total of 34,972 hospitalized patients (mean age: 67.3, SD +/- 19.3 years; female 53.6%, mean length of stay: 11.9 +/- 13.2 days, mean nursing care time per day: 3.5 +/- 1.4 hours) were observed during the study period. Overall, a total of 3,842 falls affected 2,512 (7.2%) of the hospitalized patients. From these falls, 2,552 (66.4%) were without injuries, while 1,142 (29.7%) falls resulted in minor injuries, and 148 (3.9%) falls resulted in major injuries. The overall fall rate in the hospitals' patient population was 8.9 falls per 1,000 patient days. The fall rates fluctuated slightly from 9.1 falls in 1999 to 8.6 falls in 2003. After the implementation of the IFP, in 2001 a slight decrease to 7.8 falls per 1,000 patient days was observed (p = 0.086). The annual proportion of minor and major injuries did not decrease after the implementation of the IFP. From 1999 to 2003, patient characteristics changed in terms of slight increases (female gender, age, consumed nursing care time) or decreases (length of hospital stay), as well as the prevalence of fall risk factors increased up to 46.8% in those patients who fell. CONCLUSION: Following the implementation of an interdisciplinary falls prevention program, neither the frequencies of falls nor consequent injuries decreased substantially. Future studies need to incorporate strategies to maximize and evaluate ongoing adherence to interventions in hospital falls prevention programs.

Asian Tobacco Education and Cancer Awareness Research Special Population Network. A model for reducing Asian American cancer health disparities.

Asian Americans are the fastest growing and the second largest foreign-born ethnic group in the United States. Cancer is a leading cause of death among Asian Americans. The Asian Tobacco Education and Cancer Awareness Research (ATECAR) Special Population Network, Center for Asian Health, aimed to reduce or eliminate cancer health disparities in these diverse, underserved populations in Pennsylvania, New Jersey, Delaware, and New York. The ATECAR logic model was adapted from a variety of conceptual frameworks to develop and implement the network's multifaceted cancer health disparities research, training, awareness, and outreach programs. The model was the basis for the developmental phases of the network that included (1) needs assessment, infrastructure, and partnership building; (2) intervention research, training, and mentorship; and (3) evaluation, dissemination, and diffusion. Community involvement occurred at every operational level to ensure program and network sustainability. Between 2000 and 2005, the ATECAR network consisted of 88 partners, representing a cross-section of Asian communities, academia, cancer centers, and health service agencies, ensuring a viable infrastructure for the network's multidimensional cancer health disparities programs. ATECAR's research covered tobacco control, cancer prevention and intervention, and clinical trials. More than 22 research projects were conducted and their results disseminated in peer-reviewed journals. ATECAR also trained 76 junior researchers and special population investigators and 1014 community professionals in disparity issues. ATECAR's multimedia cancer awareness education program reached over 116,000 Asians. The ATECAR network's achievements have had a profound impact on Asian Americans and established a trend toward reducing cancer health disparities, especially among underserved Asian Americans.

[The effect of procainamide on the inducibility of ventricular tachycardia using programmed stimulation].

The effect of intravenously administered procainamide (0.5-1 g, mean 0.966 g) on the inducibility of sustained ventricular tachycardia by programmed ventricular stimulation was tested in 15 patients (12 men and 3 women, mean age 57.2 +/- 16.6 years) with confirmed sustained ventricular tachycardia. Eleven patients had a previous myocardial infarction and two had congestive heart failure. The programmed ventricular stimulation (1-3 premature stimuli following after ventricular stimulation at a rate of 100/120 and 140/min. and a number of quick stimuli with a rising frequency from the apex of the right ventricle at an intensity equal to twice the diastolic threshold) was administered before and after procainamide administration. Sustained ventricular tachycardia was induced during the controlled examination in all 15 patients (100% sensitivity). Induced ventricular tachycardia had a haemodynamically important course with a rapid onset of unconsciousness in three patients whose index of risk of ventricular tachycardia (ratio of its frequency and the ejection fraction at rest) was significantly higher than in the remaining 12 patients (9.0 +/- 2.2 as compared with 4.9 +/- 1.2). Procainamide prevented the induction of sustained ventricular tachycardia in six patients (group I), i. e. in 40%. In the remaining nine patients (group II) ventricular tachycardia induced after procainamide had a significantly lower frequency (192 +/- 34/min.), as compared with controls (214 +/- 42/min.), but its haemodynamic impact was not affected. Patients of group I had, as compared with group II, a significantly higher ejection fraction (47 +/- 14% as compared with 35 +/- 10%) and a significantly lower index of the risk of tachycardia (4.5 +/- 1.3 as compared with 6.5 +/- 2.4).(ABSTRACT TRUNCATED AT 250 WORDS)

Electrophysiologic testing of bretylium tosylate in sustained ventricular tachycardia.

We used programmed ventricular stimulation to test intravenous bretylium tosylate in 10 consecutive patients with inducible sustained ventricular tachycardia (usually refractory to type I antiarrhythmic agents). These 10 patients had previously documented sustained ventricular tachycardia and/or ventricular fibrillation complicating stable heart disease. Following control inductions of sustained ventricular tachycardia, bretylium 10 mg/kg was infused over 30 minutes. Thirty minutes after this infusion, sustained ventricular tachycardia could be induced in 9 of the 10 patients (one of these nine patients also had bretylium-potentiated spontaneous ventricular tachycardia). Tachycardia induced in the nine patients after bretylium was similar to control tachycardia with respect to morphology and cycle length (333 +/- 16 msec after bretylium versus 330 +/- 16 msec during control). However, five of the nine patients tolerated induced tachycardia less well after bretylium (exacerbated hypotension). In one patient, ventricular tachycardia could not be induced after intravenous bretylium.

A modeling study on the sustainability of a certification-and-monitoring program for paratuberculosis in cattle.

Certification-and-monitoring programs for paratuberculosis are based on repetitive herd testing to establish a herd's health status. The available tests have poor sensitivity. Infected but undetected herds may remain among certified "paratuberculosis-free" herds. The objective was to determine if truly free herds acquire a certified status and keep it over time when infected but undetected herds remain. The Dutch program was used as a basis to construct a mechanistic deterministic model of the evolution over 25 years of the number of herds per health status. Three health states for herds were defined: not detected as infected in the certification process to obtain a free status; not detected as infected by any of the repetitive tests for monitoring the certified free status; detected as infected. Among undetected herds, two types were defined: truly free versus undetected but infected. Transitions between states were due to the purchase of an infected animal, infection via the environment, clearance via culling or sales, detection of an infected animal, and certification. A sensitivity analysis was carried out. We showed that--for a 100% specific test only--most of the truly free herds at the beginning of the program got a certified free status and kept it over time. Most infected herds were either detected as infected or cleared. The number of certified truly free herds increased with a decrease in the animal-level prevalence or in the risk of purchasing an infected cattle, for example by restricting purchases to cattle from herds at the highest level of certification.
