Pragmatic Return to Effective Dental Infection Control through Triage and Testing (PREDICT): an observational, feasibility study to improve dental office safety

BACKGROUND

During the COVID-19 pandemic, there was a substantial interruption of care, with patients and workers fearful to return to the dental office. As dental practice creates a highly aerosolized environment, the potential for spread of airborne illness is magnified. As a means to increase safety and mitigate risk, pre-visit testing for SARS-CoV-2 has the potential to minimize disease transmission in dental offices. The Pragmatic Return to Effective Dental Infection Control through Testing (PREDICT) Feasibility Study examined the logistics and impact of two different testing mechanisms (laboratory-based PCR viral testing and point-of-care antigen testing) in dental offices.

METHODS

Dental healthcare workers (DHCWs) and patients in four dental offices within the National Dental Practice-based Research Network participated in this prospective study. In addition to electronic surveys, participants in two offices completed POC testing, while participants in two offices used lab-based PCR methods to detect SARS-CoV-2 infection. Analysis was limited to descriptive measures, with median and interquartile ranges reported for Likert scale responses and mean and standard deviation for continuous variables.

RESULTS

Of the total 72 enrolled, 28 DHCWs and 41 patients completed the protocol. Two patients (4.9%) tested positive prior to their visit, while 2 DHCWs (12.5%) tested positive for SARS-CoV-2 infection at the start of the study. DHCWs and patients shared similar degree of concern (69% and 63%, respectively) for contracting COVID-19 from patients, while patients feared contracting COVID-19 from DHCWs less (49%). Descriptive statistics calculations revealed that saliva, tongue epithelial cells, and nasal swabs were the most desirable specimen collection method; both testing (LAB and POC) protocols took similar amounts of total time to complete; and DHCWs and patients reported feeling more comfortable when both groups were tested.

CONCLUSIONS

While a larger-scale, network study is necessary for generalizability of results, this feasibility study suggests that SARS-CoV-2 testing can be effectively implemented into dental practice workflows and positively impact perception of safety for DHCWs and patients. As new virulent infectious diseases emerge, preparing dental personnel to employ an entire toolbox of risk mitigation strategies, including testing, may have the potential to decrease dental practice closure time, maintaining continuity of dental care services for patients.

Leveraging the functionality of Research Electronic Data Capture (REDCap) to enhance data collection and quality in the Opioid Analgesic Reduction Study

BACKGROUND

The Opioid Analgesic Reduction Study is a double-blind, prospective, clinical trial investigating analgesic effectiveness in the management of acute post-surgical pain after impacted third molar extraction across five clinical sites. Specifically, Opioid Analgesic Reduction Study examines a commonly prescribed opioid combination (hydrocodone/acetaminophen) against a non-opioid combination (ibuprofen/acetaminophen). The Opioid Analgesic Reduction Study employs a novel, electronic infrastructure, leveraging the functionality of its data management system, Research Electronic Data Capture, to not only serve as its data reservoir but also provide the framework for its quality management program.

METHODS

Within the Opioid Analgesic Reduction Study, Research Electronic Data Capture is expanded into a multi-function management tool, serving as the hub for its clinical data management, project management and credentialing, materials management, and quality management. Research Electronic Data Capture effectively captures data, displays/tracks study progress, triggers follow-up, and supports quality management processes.

RESULTS

At 72% study completion, over 12,000 subject data forms have been executed in Research Electronic Data Capture with minimal missing (0.15%) or incomplete or erroneous forms (0.06%). Five hundred, twenty-three queries were initiated to request clarifications and/or address missing data and data discrepancies.

CONCLUSION

Research Electronic Data Capture is an effective digital health technology that can be maximized to contribute to the success of a clinical trial. The Research Electronic Data Capture infrastructure and enhanced functionality used in Opioid Analgesic Reduction Study provides the framework and the logic that ensures complete, accurate, data while guiding an effective, efficient workflow that can be followed by team members across sites. This enhanced data reliability and comprehensive quality management processes allow for better preparedness and readiness for clinical monitoring and regulatory reporting.

Impact of DHCWs' Safety Perception on Vaccine Acceptance and Adoption of Risk Mitigation Strategies

OBJECTIVES

To estimate the association between safety perception on vaccine acceptance and adoptions of risk mitigation strategies among dental health care workers (DHCWs).

METHODS

A survey was emailed to DHCWs in the New Jersey area from December 2020 to January 2021. Perceived safety from regular SARS-CoV-2 testing of self, coworkers, and patients and its association with vaccine hesitancy and risk mitigation were ascertained. Risk Mitigation Strategy (RiMS) scores were computed from groupings of office measures: 1) physical distancing (reduced occupancy, traffic flow, donning of masks, minimal room crowding), 2) personal protective equipment (fitted for N95; donning N95 masks; use of face shields; coverings for head, body, and feet), and 3) environmental disinfection (suction, air filtration, ultraviolet, surface wiping).

RESULTS

SARS-CoV-2 testing of dental professionals, coworkers, and patients were perceived to provide safety at 49%, 55%, and 68%, respectively. While dentists were least likely to feel safe with regular self-testing for SARS-CoV-2 (P < 0.001) as compared with hygienists and assistants, they were more willing than hygienists (P = 0.004; odds ratio, 1.79 [95% CI, 1.21 to 2.66]) and assistants (P < 0.001; odds ratio, 3.32 [95% CI, 1.93 to 5.71]) to receive the vaccine. RiMS scores ranged from 0 to 19 for 467 participants (mean [SD], 10.9 [2.9]). RiMS scores did not significantly differ among groups of DHCWs; however, mean RiMS scores were higher among those who received or planned to receive the COVID-19 vaccine than those with who did not (P = 0.004). DHCWs who felt safer with regular testing had greater RiMS scores than those who did not (11.0 vs. 10.3, P = 0.01).

CONCLUSIONS

Understanding DHCWs' perception of risk and safety is crucial, as it likely influences attitudes toward testing and implementation of office risk mitigation policies. Clinical studies that correlate risk perception and RiMS with SARS-CoV-2 testing are needed to demonstrate the effectiveness of RiMS in dental care settings.

KNOWLEDGE TRANSFER STATEMENT

Educators, clinicians, and policy makers can use the results of this study when improving attitudes toward testing and implementation of risk mitigation policies within dental offices, for current and future pandemics.

The Pragmatic Return to Effective Dental Infection Control Through Triage and Testing (PREDICT) Study: Protocol for a Prospective Clinical Study in the National Dental Practice-Based Research Network

BACKGROUND

Dental practice has been greatly affected by the COVID-19 pandemic. As SARS-CoV-2 infection is transmitted by respiratory fluids, dental practice techniques, which include aerosol-generating procedures, can increase the risk of transmission causing heightened safety concerns for both dental health care workers (DHCWs) and patients. These concerns have resulted in the reduction in patient volume and the available workforce within dental practices across the United States. Standardized methods for COVID-19 triage and testing may lead to increased safety and perceptions of safety for DHCWs and their patients and promote willingness to provide and access oral health care services.

OBJECTIVE

This study is designed to develop procedures that test the feasibility of enhanced COVID-19 triage and testing in dental offices. It will provide preliminary data to support a larger network-wide study grant application aimed at developing protocols to address safety concerns of patients and DHCWs in a peri-COVID-19 pandemic era.

METHODS

The feasibility study is being conducted in 4 private dental practices, each of which has a dentist member of the National Dental Practice-Based Research Network. Participants include the DHCWs and patients of the dental practice. Study procedures include completion of COVID-19 triage, completion of COVID-19 testing (point-of-care [POC] or laboratory-based [LAB] SARS-CoV-2 viral, antigen, and antibody tests based on office designation), and administration of perception and attitude surveys for participating DCHWs and patients of the dental practice over a defined study period. The office designation and the participant's role in the practice determines which testing protocol is executed within the office. There are 4 study groups following 4 distinct protocols: (1) POC DHCWs, (2) POC patients, (3) LAB DHCWs, and (4) LAB patients.

RESULTS

Data collection began in December of 2021 and concluded in March 2022. Study results are expected to be published in fall 2022.

CONCLUSIONS

The results of this feasibility study will help identify the viability and functionality of COVID-19 triage and testing in dental practices and inform a larger network-wide study grant application that develops protocols that address safety concerns of patients and DHCWs in a COVID-19 environment.

The Opioid Analgesic Reduction Study (OARS)-a comparison of opioid vs. non-opioid combination analgesics for management of post-surgical pain: a double-blind randomized clinical trial

Background

Everyday people die unnecessarily from opioid overdose-related addiction. Dentists are among the leading prescribers of opioid analgesics. Opioid-seeking behaviors have been linked to receipt of initial opioid prescriptions following the common dental procedure of third molar extraction. With each opioid prescription, a patient’s risk for opioid misuse or abuse increases. With an estimated 56 million tablets of 5 mg hydrocodone annually prescribed after third molar extractions in the USA, 3.5 million young adults may be unnecessarily exposed to opioids by dentists who are inadvertently increasing their patient’s risk for addiction.

Methods

A double-blind, stratified randomized, multi-center clinical trial has been designed to evaluate whether a combination of over-the-counter non-opioid-containing analgesics is not inferior to the most prescribed opioid analgesic. The impacted 3rd molar extraction model is being used due to the predictable severity of the post-operative pain and generalizability of results. Within each site/clinic and gender type (male/female), patients are randomized to receive either OPIOID (hydrocodone/acetaminophen 5/300 mg) or NON-OPIOID (ibuprofen/acetaminophen 400/500 mg). Outcome data include pain levels, adverse events, overall patient satisfaction, ability to sleep, and ability to perform daily functions. To develop clinical guidelines and a clinical decision-making tool, pain management, extraction difficulty, and the number of tablets taken are being collected, enabling an experimental decision-making tool to be developed.

Discussion

The proposed methods address the shortcomings of other analgesic studies. Although prior studies have tested short-term effects of single doses of pain medications, patients and their dentists are interested in managing pain for the entire post-operative period, not just the first 12 h. After surgery, patients expect to be able to perform normal daily functions without feeling nauseous or dizzy and they desire a restful sleep at night. Parents of young people are concerned with the risks of opioid use and misuse, related either to treatments received or to subsequent use of leftover pills. Upon successful completion of this clinical trial, dentists, patients, and their families will be better able to make informed decisions regarding post-operative pain management.

COVID-19 and Dentistry: Biological Considerations, Testing Strategies, Issues, and Regulations

The COVID-19 pandemic has created a new and demanding work environment for health professionals. This article will focus on the biological issues related to infection and disease, tests developed based on these biological principles, the ways in which these tests are evaluated, and how they can be used to protect both patients, dental professionals, and office affiliates. The article will describe types of COVID-19 testing that may be performed in dental offices, the issue of testing and anxiety, regulations regarding testing that are relevant to dentists, rules for delivery and reimbursement, and strategies for proceeding as a health professional in the current challenging environment. The authors conclude that the devastating effects of the pandemic on public health has facilitated a new role for dentists as public health professionals, with the opportunity for the dental profession to actively expand its participation in improving the health of the public moving forward. Testing will continue as a means of relieving anxiety for the public.

Elements of Undergraduate Education Related to Students' Academic Performance in the First Year of Dental School

The aim of this study was to improve understanding of predictors of student success in dental school. A total of 178 student records from the Classes of 2015 and 2016 at a U.S. dental school were reviewed for this retrospective study. The records assessed included admissions files with such elements as scores on the Dental Admission Test (DAT), participation in a pipeline program, and undergraduate transcripts; academic records from the first term of dental school (class rank, course remediation, and withdrawal/dismissal from dental school); and National Board Dental Examination (NBDE) Part I results. The results showed that the DAT Perceptual Ability Test was positively related to performance in the first term of dental school (p=0.030). The DAT Academic Average (p<0.0001) and participation in a pipeline program (p=0.006) were found to be predictors of performance in the lower 25% of the class by end of first term rank. Taking organic chemistry in a summer term during undergraduate study was identified as a predictor variable for dismissal, withdrawal, or entry into a decompressed curriculum (p=0.025). Although this analysis found that traditional predictors of academic success in dental school were associated with strong academic performance in the study sample, it also provided a more complex assessment of factors that may be associated with students who struggle in the first year. As the vast majority of students in this sample successfully completed dental school, the results were not sought to inform admissions criteria, but rather to help academic and student affairs officers identify at-risk students in order to offer timely intervention.

Interprofessional education in dental education: An international perspective

Interprofessional collaborative care (IPC) is defined as working within and across healthcare disciplines and is considered essential to achieve a more inclusive, patient-centred care, provide a means to support patient safety and address global healthcare provider shortages. Interprofessional education (IPE) provides the knowledge and experience students need to achieve these goals. ADEE/ADEA held a joint international meeting 8-9 May 2017, with IPE being one of four topic areas discussed. The highly interactive workshop format, where "everyone was an expert," supported discussion, sharing and creative problem-solving of over seventy-one participants from twenty-nine countries. IPE participants broke out into five groups over a two-day period discussing three main areas: challenges and barriers to implementing IPE within their institution or country; discussion of successful models of introducing and assessing IPE initiatives, and exploring best practices and next steps for implementation for each group member. A mind-mapping model was used to graphically display participants' thoughts and suggestions. Key themes, revealed through the visual mind maps and discussion, included the following: IPE should lead to and enhance patient-centred care; student involvement is key to IPE success; faculty development and incentives can facilitate adoption and implementation of IPE; the role of a "champion" and leadership structure and commitment is important to move IPE forward; and IPE must be tailored to the unique issues found in each country. Overall, there was a high level of interest to continue both collaboration and discussion to learn from others beyond the London meeting.

New Dental Accreditation Standard on Critical Thinking: A Call for Learning Models, Outcomes, Assessments

This opinion article applauds the recent introduction of a new dental accreditation standard addressing critical thinking and problem-solving, but expresses a need for additional means for dental schools to demonstrate they are meeting the new standard because articulated outcomes, learning models, and assessments of competence are still being developed. Validated, research-based learning models are needed to define reference points against which schools can design and assess the education they provide to their students. This article presents one possible learning model for this purpose and calls for national experts from within and outside dental education to develop models that will help schools define outcomes and assess performance in educating their students to become practitioners who are effective critical thinkers and problem-solvers.

Periodontal-systemic disease education in U.S. and Canadian dental schools

Research has proliferated in recent years regarding the relationship of oral disease to systemic conditions. Specifically, periodontal disease has been studied as a potential risk factor for multiple conditions such as cardiovascular disease (CVD) and adverse pregnancy outcomes, while other research focuses on exposures or behaviors associated with oral disease. However, few articles have been published reporting how this information is integrated into schools of dentistry, both in the classroom and clinical curriculum. For our study, a thirty-three-item survey and cover letter were electronically mailed to academic deans at sixty-five accredited dental schools in the United States and Canada in the fall of 2007. The response rate was 77 percent. According to the responses to this survey, the primary topics covered in the didactic curriculum regarding periodontal oral-systemic disease are aging, CVD, diabetes, and tobacco use. Eighty-eight percent of the respondents reported that their students are knowledgeable about the role of inflammation and its impact on oral-systemic conditions. Forty-eight percent of the respondents said they provide formal training for their students in how to discuss or communicate aspects of periodontal oral-systemic disease with patients. Only seven schools reported teaching didactic content to dental students intermixed with other health professions students, and only two schools reported conducting joint projects. Only 9 percent of the respondents said they think nurses and physicians are knowledgeable about oral-systemic disease. The findings indicate that dental schools are confident about the knowledge of their students regarding oral-systemic content. However, much work is needed to educate dental students to work in a collaborative fashion with other health care providers to co-manage patients at risk for oral-systemic conditions.

Academic integrity in dental school: a call to action

Recently there has been much discussion in the media and literature pertaining to academic misconduct in higher education. Dentistry has not been immune to this discussion. Recent "scandals" involving student misconduct in U.S. dental schools have sparked dialogue within dentistry's premier professional organizations. The authors of this position paper recognize that academic misconduct can be a serious threat to dental education and the profession of dentistry as a whole. This paper addresses academic misconduct in dental school, the impact it may have on our profession, and how educators can begin to develop strategies to curtail cheating in their institutions.

Implementation of a Digital Radiographic Image Acquisition and Retrieval System (DRIARS) using a wireless network in an orthodontic department

AIM

The objective of this report is to describe the implementation and pilot-test of an integrated wireless local area network (WLAN) system that incorporated the Planmeca Promax CCD based digital panoramic/cephalometric x-ray system, Dolphin(R) software, and multiple remote user units to increase the efficiency of data management by the residents in the Department of Orthodontics.

BACKGROUND

The Department of Orthodontics of the New Jersey Dental School (NJDS) acquired the Dolphin cephalometric analysis software and the Planmeca Promax digital panoramic/cephalometric x-ray units on separate occasions. Dolphin has been in use for many years at this institution, the current version being 10, and the Promax was acquired in the Fall of 2002. The digital panoramic and cephalometric radiographs were acquired and stored separately in the Planmeca's Dimaxis database.

REPORT

During the incorporation of the WLAN, there was an opportunity to research and install the best available security system for the WLAN so it could be a network model for the other departments within the dental school and perhaps other dental schools around the nation.

SUMMARY

Digital radiographs, once obtained, can be stored locally or transmitted securely to remote locations via a local area network. This article describes the selection criteria and methodology that would optimize the transmission and retrieval of such images instantaneously on demand at chair side locations. This will not only save significant clinical time but will enhance the productivity of the clinic in the long run.

'Schools without walls?' Developments and challenges in dental outreach teaching - report of a recent symposium

During the 2004 annual meeting of the International Association for Dental Research, the Education Research Group held a symposium on dental outreach teaching. After a brief introduction, which reviews relevant aspects of the relatively sparse literature, this paper summarises the proceedings, the themes and conclusions that emerged and the research issues that were identified. It aims to describe aspects of current practice around the world and to promote future discussion. Presenters gave details of outreach programmes for dental undergraduates in Australia, Finland, Malaysia (and Southeast Asia), the United Kingdom and the United States. From these presentations four themes emerged. They were: reasons for the introduction of outreach teaching, its perceived beneficial effects, organisational issues, educational issues. The reasons included a recognition of the need to educate dental undergraduates as members of 'care teams' in the environments and communities where they were ultimately like to work and the current shortage of both suitable patients and teachers (faculty) in many dental schools. A wide range of potential benefits and some disadvantages were identified. The organisational issues were, in the main, seen to relate to finance and administration. The educational issues included the need to train and monitor the performance of teachers at outreach clinics and to assess the performance of the undergraduates whilst at the outreach locations. It was concluded that new technology made it easier to teach at a distance and it was possible to create a dental 'school without walls'. It was recognised that few evaluations of dental outreach teaching have been carried out and that there were many research questions to be answered, including: whether it should be a voluntary or compulsory part of the undergraduate curriculum, how long it should last and what type of outcomes should be assessed.

Clinical competence of graduates of community-based and traditional curricula

As community-based dental education programs proliferate, so do concerns about the quality of education at extramural sites. While there have been some comparisons of the effects of community-based programs on attitudes and perceptions of competency, there is virtually no information about whether such programs can train students to carry out standard dental procedures as well as if they were prepared in the dental school proper. To address this gap in our knowledge about the educational outcomes of community-based programs, the following performance measures were retrospectively compared for 457 students in traditional senior year curricula and fifty seniors in a community-based program: scores and pass/fail rates on the Northeastern Regional Boards (NERB), clinical production, passage of competencies, and on-time graduation rates. Students in the CODE (Community-Oriented Dental Education) program at the University of Medicine and Dentistry of New Jersey (UMDNJ)-New Jersey Dental School (NJDS) demonstrated significantly higher scores on the restorative section of the NERB, but this did not translate into a better overall pass rate. CODE students passed the same competencies as graduates of the traditional program, yet demonstrated appreciably higher clinical productivity and on-time graduation rates. The additional clinical experiences for the CODE students may be a factor in their higher board scores. Based on these data, it is concluded that community-based dental educational programs can be at least as effective as intramural (school-based) educational experiences in providing students with a sound clinical education.

Alumni perspectives on community-based and traditional curricula

In 1994, the University of Medicine and Dentistry of New Jersey-New Jersey Dental School (UMDNJ-NJDS) launched the Community-Oriented Dental Education (CODE) program. The CODE program provides senior dental students the opportunity to spend four days per week providing dental care in a community-based clinic. A survey of graduates of CODE (n = 55) and randomly selected graduates of the traditional curriculum (n = 110) was conducted via mail to determine attitudes relating to community service (CS), community-based learning (CBL), reasons for participating in their clinical program, perceived levels of clinical preparedness at graduation, and practice choices. A total of 111 surveys (66.9 percent) were returned to NJDS, with 84.6 percent of CODE alumni responding and 59.0 percent of traditional alumni (TA) responding. Of the 111 surveys returned, sixty-five (58.6 percent) were completed by TA, and forty-six (41.4 percent) were completed by CODE alumni. There were no differences among CODE and TA regarding attitudes toward CS and tendency to practice in underserved areas or to accept Medicaid payments. There were, however, some differences in attitudes toward CBL, reasons for applying or not applying to the CODE program, perceived impact of clinical education on graduates' preparedness, views of the extent to which the programs encouraged students to choose public or private areas of practice, and perceptions of how the desire to help communities influenced career and practice decisions. Some of these findings may be useful to schools as they plan extramural education programs.

Comparative anticaries efficacy of sodium fluoride and sodium monofluorophosphate dentifrices. A two-year caries clinical trial on children in New Jersey and Puerto Rico

PURPOSE

To provide a head-to-head comparison of the anticaries efficacy associated with two commercially-available and American Dental Association-accepted dentifrices: Crest Cavity Fighting Toothpaste with Fluoristat, containing 0.243% sodium fluoride in a silica base, and Colgate Great Regular Flavor Fluoride Toothpaste, containing 0.76% sodium monofluorophosphate in a dicalcium phosphate dihydrate base. The study was conducted in harmony with the published 1988 American Dental Association guidelines for studies geared toward this purpose.

MATERIALS AND METHODS

The study employed a double-blind, parallel-groups, multi-center two-treatment design, and involved third, fourth, and fifth grade schoolchildren from Newark, New Jersey, and from the Cidra and Lares areas of Puerto Rico. Qualifying subjects were stratified according to age and sex, and were randomly assigned to the two treatment groups, with multiple subjects in the same household all assigned to the dentifrice randomly allocated to the first among them. Caries examinations were conducted in accordance with U.S. Food and Drug Administration guidelines for the clinical evaluation of drugs to prevent dental caries. After treatment assignment, study participants were instructed to brush their teeth at home with their assigned dentifrice at least twice daily. Brushing instructions were reinforced by the presentation of educational films and lectures at school, by semi-annual mailings to parents, and through the periodic distribution of small novelty gifts along with the dentifrice deliveries, in order to enhance the interest and enthusiasm of study participants. Post-baseline examinations were performed after 1 and after 2 yrs of product use. Two thousand four hundred seventy-nine (2,479) subjects completed this 2-yr study. For these subjects, the mean (S.D.) DFS scores at baseline were 2.77 (3.35) for the Crest group, and 2.66 (3.18) for the Colgate group. For caries increment after 1 yr, the respective means were 1.68 (2.53) and 1.70 (2.57). After 2 yrs, the mean caries increments were 3.56 (4.11) for the Crest group, and 3.56 (4.05) for the Colgate group.

RESULTS

The analysis of the 2-yr caries increment scores support the conclusion that the anticaries efficacy associated with Colgate Great Regular Flavor Fluoride Toothpaste is equivalent to that associated with Crest Cavity Fighting Toothpaste with Fluoristat, in accordance with the procedures and standards provided by the published guidelines of the American Dental Association. Further, consistent with those same standards, the results of this study serve to lend additional support to the conclusion that dentifrices formulated with sodium monofluorophosphate provide an equivalent level of anticaries efficacy as to those formulated with sodium fluoride.

Community-based dental programs: University of Medicine and Dentistry of New Jersey-New Jersey Dental School

The dental school plans to incorporate CODE into the curriculum so that more students have community-based dental educational experiences. Future plans also include increasing standardization of reports, clinical and administrative procedures, resources, and processes across the sites in order to lower managerial overhead. This process will be aided by further enhancement of computerized information systems and electronic links. The major lesson learned is that new extramural programs can be created and sustained by pooling school resources with those from the private and public sectors. Funding sources and opportunities available to one party alone are insufficient. While one-time funding was used to build and furnish the NJDS extramural sites, the clinics were established only after business plans demonstrated the availability of funds to sustain their operations. The Statewide Network of Community Oral Health Care and CODE models are still evolving, but they are replicable not only in dental education but in other types of health services. The details of the partnerships and funding streams will vary from site to site, but through outreach and careful negotiation with potential partners and detailed contracts, the community service and educational missions of a health professions school can have a successful outcome.

[Multicenter study of intracoronary stent implantation in Rio de Janeiro]

PURPOSE

To evaluate retrospectively stent implantation (SI) in patients with coronary artery disease (CAD) performed in 7 hospitals in Rio de Janeiro.

METHODS

From June/94 to December/96 2,220 procedures were performed among which we analyzed 783 SI in 660 (29.7%) patients using coronary angiography without digital subtraction. Several types of stents were used: Palmaz-Schatz (40.9%), Gianturco-Roubin (29.1%) e NIR (22.0%). Indications for SI: 1--de novo lesion (67.9%); 2) restenotic lesion (16.0%); 3) sub-optimal results after PTCA (8.2%); 4) abrupt or threatened closure after PTCA (4.9%); 5) chronic occlusion (3.0%). All stents were implanted using high pressure balloon inflation without intracoronary ultrasound guidance. Sub-acute stent thrombosis prevention, in the majority of patients (87.8%) was done with ticlopidine and aspirin.

RESULTS

Early outcome: a) the success rate of SI in 770 lesions was 98.0% in 646 (97.9%) patients; b) the clinical success rate in 634 patients was 96.0%; c) the major complications were acute myocardial infarction (1.1%); coronary artery bypass graft (1.4%) and death (0.8%); d) vascular complications with surgical correction and/or bleeding occurred in 3.0%. Late outcome: a) the clinical follow-up of 399 (60.4%) and the coronary angiographies of 121 patients (30.3%) showed in-stent lesion in 79 (19.8%); b) other event rates: myocardial infarction (1.5%); coronary bypass (2.3%); death: 1.0% and other PTCA or similar procedure (12.5%).

CONCLUSION

This multicentric study showed that SI for CAD can be performed with safety, high early success rate, few complications and low rate of cardiac events during the late follow-up.

Special Olympics, special smiles: assessing the feasibility of epidemiologic data collection

No comprehensive national study has ever been completed on the oral health status of people with disabilities, their patterns of use of oral health services and access-to-care barriers. The authors describe the Special Olympics, Special Smiles program, conducted as part of the New Jersey Summer Special Olympics Games, and assess a pilot-tested model for collecting epidemiologic data. The results of this initial data collection are also compared with the goals of the U.S. Public Health Service, as outlined in the Healthy People 2000 publication.

Urinary mercury levels before and after amalgam restoration

Urinary mercury levels and excretion rates were measured to determine the effect of dental amalgam restoration on the mercury body burden. No consistent increase in urinary mercury concentrations was found among subjects who had a single restoration, but a continuously increasing statistically significant (P < 0.05) trend, that was 33% above background levels, was detected between 9 and 12 days after restoration, in the subject with four restorations in a single day. The current findings suggested that even though amalgam restorations can cause an increase in mercury body burden, the elevation above background levels is small and thus the risks associated with the use of this material are considered minimal for the general population.

Implementing and evaluating a patient instructor program

A Patient Instructor (PI) program designed to improve students' data-gathering and interpersonal skills is evaluated. Each student in two consecutive classes of third-year students (class of 1996, n = 60; class of 1997, n = 72) interviewed four patient instructors (PIs) during a three-hour rotation. Each PI portrayed one of six scenarios. PIs assessed students using content checklists and an abbreviated Arizona Clinical Interview Rating Scale (ACIR). After the interview, each PI gave student constructive feedback regarding interpersonal behavior and ability to identify salient content items from the patient's history. Significant improvement was observed on content checklists (p < 0.01) between the first and second rounds. Significant improvement was also noted on the ACIR (p < 0.01) between rounds one, two and three. The results indicate that data-gathering and interpersonal skills can be enhanced by using patient instructors. Student evaluation of the program was positive.

An application of outcomes assessment in dental education

The outcomes assessment process developed by the New Jersey Dental School is described. The paper identifies required resources, presents selected outcome measures, reviews strengths and weaknesses of the process, and reports how ongoing assessment activities have evolved. Documentation produced as part of the outcomes assessment process is also described, allowing health professions schools to implement a similar process.

Impact of quality assurance program: providing practice assessment

Participation in a self-administered quality assessment (SAQA) program led to changes in New Jersey dentists' perceptions of practice quality. Ninety-four percent indicated they discovered practice deficiencies. This study suggests that using a self-administered quality assessment program, such as the SAQA program, can lead to a better understanding of a practice's strengths and weaknesses.
