Advancing infection control in dental care settings: factors associated with dentists' implementation of guidelines from the Centers for Disease Control and Prevention.

BACKGROUND AND OVERVIEW: The authors set out to identify factors associated with implementation by U.S. dentists of four practices first recommended in the Centers for Disease Control and Prevention's Guidelines for Infection Control in Dental Health-Care Settings-2003. METHODS: In 2008, the authors surveyed a stratified random sample of 6,825 U.S. dentists. The response rate was 49 percent. The authors gathered data regarding dentists' demographic and practice characteristics, attitudes toward infection control, sources of instruction regarding the guidelines and knowledge about the need to use sterile water for surgical procedures. Then they assessed the impact of those factors on the implementation of four recommendations: having an infection control coordinator, maintaining dental unit water quality, documenting percutaneous injuries and using safer medical devices, such as safer syringes and scalpels. The authors conducted bivariate analyses and proportional odds modeling. RESULTS: Responding dentists in 34 percent of practices had implemented none or one of the four recommendations, 40 percent had implemented two of the recommendations and 26 percent had implemented three or four of the recommendations. The likelihood of implementation was higher among dentists who acknowledged the importance of infection control, had practiced dentistry for less than 30 years, had received more continuing dental education credits in infection control, correctly identified more surgical procedures that require the use of sterile water, worked in larger practices and had at least three sources of instruction regarding the guidelines. Dentists with practices in the South Atlantic, Middle Atlantic or East South Central U.S. Census divisions were less likely to have complied. CONCLUSIONS: Implementation of the four recommendations varied among U.S. dentists. Strategies targeted at raising awareness of the importance of infection control, increasing continuing education requirements and developing multiple modes of instruction may increase implementation of current and future Centers for Disease Control and Prevention guidelines.

Preparing whistleblowers for reporting research misconduct.

Making an allegation of research misconduct can be stressful for a whistleblower. The Research Integrity Officer (RIO) can play an important role in helping reduce the stress by thoroughly discussing what whistleblowers can expect if they make an allegation. Through interviews with 77 RIOs who had recently handled a research misconduct case, we found that RIOs who addressed more topics as well as specific aspects of the topics were more likely to have used some type of memory aide in their initial contact with whistleblowers, talked with ORI staff or other RIOs about "hypothetical" research misconduct cases, or attended a RIO boot camp training. We believe that RIOs who more fully inform whistleblowers are providing timely preparation and building whistleblowers' confidence so they can make a more informed decision about reporting and experience less stress.

Assessing the preparedness of research integrity officers (RIOs) to appropriately handle possible research misconduct cases.

Institutions receiving federal funding for research from the U.S.Public Health Service need to have policies and procedures to both prevent research misconduct and to adjudicate it when it occurs. The person who is designated to handle research misconduct is typically referred to as the research integrity officer (RIO). In this interview study we report on 79 RIOs who describe how they would handle allegations of research misconduct. Their responses were compared to two expert RIOs. The responses to the allegations in the scenarios demonstrated that RIOs are not uniformly well prepared to handle activities associated with reported allegations of research misconduct. We recommend greater preparation through directed training, use of check lists of possible behaviors necessary to consider when situations arise, being involved in a network of RIOs so one can discuss options, and the possible need to certify RIOs.

Health literacy impact on patient-provider interactions involving the treatment of dental problems.

Health literacy-related problems can interfere with effective doctor-patient communication and effective patient care. This study examined several health literacy-related markers for patients seeking treatment in hospital emergency departments and physician and dentist offices for dental problems and injuries. Participants consisted of low-income white, black, and Hispanic adults who had experienced a dental problem or injury during the previous twelve months and who visited a hospital emergency department, physician, or dentist for treatment. A stratified random sample of Maryland households participated in a cross- sectional telephone survey. Interviews were completed with 94.8 percent of 423 eligible individuals. Multivariable logistic regression analyses were performed. Only 10.0 percent of the respondents expressed a difficulty understanding what they were told by the health provider, while 4.9 percent expressed a difficulty understanding the dental or medical forms they were asked to complete and 6.9 percent reported that they had difficulty getting the health provider to understand their dental problem or injury. Logistic regression analysis found that males and Hispanics were significantly (p<0.05) more likely to experience health literacy-related problems. In general, respondents did not express health literacy-related problems. Additional research is needed to identify health literacy-related barriers to effective patient-provider communication.

Behavioral and socioeconomic correlates of dental problem experience and patterns of health care-seeking.

BACKGROUND: To recognize and better understand barriers to dental care, the authors studied behavioral and socioeconomic factors specific to low-income and minority populations that contribute to patterns of professional health care-seeking. METHODS: A stratified random sample of 27,002 Maryland households participated in a cross-sectional telephone survey. The authors targeted respondents who were low-income non-Hispanic white, non-Hispanic black or Hispanic who had experienced a dental problem or injury during the previous 12 months, as well as similar people with higher incomes for comparison. A total of 94.8 percent (401 of 423) of eligible people completed the survey. RESULTS: Logistic regression modeling (95 percent confidence interval) revealed that the respondents' race or ethnicity and sex were associated with the number of dental problems experienced during the previous 10 years, and that having a regular source of medical care and the type of dental problem experienced were associated with earlier health care-seeking. The first choice of treatment site (physician's office, emergency department or dentist's office) was associated with the respondents' income, pain level, number of problems experienced in the past 10 years and the degree to which their problem was a burden. CONCLUSIONS: The authors found that predisposing, enabling and need-based factors were associated with dental problem experience and patterns of professional health care service use.

Comparison of patient visits to emergency departments, physician offices, and dental offices for dental problems and injuries.

OBJECTIVES: Our understanding of the use of emergency departments (EDs) and physician offices for the management of dental problems is limited. We undertook this study to examine whether there are differences in their use by low-income White and minority adults as compared with higher-income adults. METHODS: Participantsincluded White, Black, and Hispanic adults who had experi enced a dental problem during the previous 12 months and who visited a physician, ED, or dentist for treatment. We selected a stratified random sample of 27,002 Maryland households with listed telephones to screen for eligibility. We identified 1,387 households with an eligible adult, selected 423 for interviews, and completed interviews with 401 (94.8%). RESULTS: To restore correct proportionality to the sample, and to adjust for nonresponse and the distribution of demographic characteristics, weights were created for use in the analyses. Only 7.1 percent of respondents contacted an ED, while 14.3 percent contacted a physician and 90.2 percent a dentist. The vast majority of respondents who contacted an ED (96.0%) or a physician (92.2%) also contacted a dentist. Lower-income respondents were more likely to seek care from an ED, while higher-income respondents were more likely to seek care from a dentist. Over whelmingly, respondents visiting EDs (89.4%) and physicians (51.7%) were instructed to see a dentist or given prescriptions/samples. Treatment provided by EDs, physicians, and dentists was not associated with the respondent's income or race/ethnicity. CONCLUSIONS: Respondents visiting EDs and physicians typically did not receive definitive care and subsequently visited a dentist for treatment.

Comparison of patient centeredness of visits to emergency departments, physicians, and dentists for dental problems and injuries.

BACKGROUND: Patient-centered care has a positive impact on patient health status. This report compares patient assessments of patient centeredness during treatment in hospital emergency departments (EDs) and physician and dentist offices for dental problems and injuries. RESEARCH DESIGN: Participants included low-income White, Black, and Hispanic adults who had experienced a dental problem or injury during the previous 12 months and who visited an emergency department, physician, or dentist for treatment. A stratified random sample of Maryland households participated in a cross-sectional telephone survey. Interviews were completed with 94.8% (401/423) of eligible individuals. Multivariable logistic regression analyses were performed. RESULTS: The measure of predictive power, the pseudo-R2s, calculated for the logistic regression models ranged from 12% to 18% for the analyses of responses to the measures of patient centeredness (satisfaction with treatment, careful listening, thorough explaining, spending enough time, and treated with courtesy and respect). EDs were less likely than dentists to treat patients with great courtesy and respect. CONCLUSIONS: Further research is needed to identify factors that support patient-centered care.

Low-income and minority patient satisfaction with visits to emergency departments and physician offices for dental problems.

OBJECTIVES: Individuals lacking access to dentists may use hospital emergency departments (EDs) or physicians (MDs) for the management of their dental problems. This study examined visits by minority and low-income individuals to physicians and hospital emergency departments for the treatment of dental problems with the goal of exploring the nature of treatment provided and patient satisfaction with the care received. METHODS: Eight focus group sessions were conducted with 53 participants drawn from low-income White, Black, and Hispanic adults who had experienced a dental problem and who had sought MD/ED care at least once during the previous 12 months. RESULTS: Toothache pain or more generalized jaw/face pain was the most frequent oral problem resulting in MD/ED visits. Pain severity was the principle reason for seeking care from MDs/EDs, with financial barriers most often mentioned as the reason for not seeking care from dentists. Expectations of MD/ED visits were generally consistent with care received; most participants limited their expectations to the provision of antibiotics or pain medication. Nearly all of the participants thought they would eventually need to see a dentist for resolution of their dental problem. CONCLUSIONS: Poor/minority individuals seek relief from oral pain through MDs/ EDs while recognizing that such care is not definitive.

Toothache pain: behavioral impact and self-care strategies.

A computer-assisted telephone interview in Maryland of adults who had low income and were Hispanic, Black, and White and who had experienced a toothache during the previous 12 months was conducted. Respondents reported a high prevalence of toothaches, with 44.3% having experienced more than five toothaches during the preceding 10 years. Pain intensity associated with the most recent toothache was high with 45.1% of the respondents reporting the highest pain possible. Pain interfered with many aspects of normal functioning. Self-care strategies generally took precedence over professional health services. Pain sufferers used a combination of self-care and formal care strategies. Initial strategies most often focused on nonprescription medicines(home remedies and prayer. The majority of respondents ultimately sought pain relief from a dentist. We identified a number of significant differences in the strategies used across racial/ethnic groups.

Role of pharmacists in consulting with the underserved regarding toothache pain.

OBJECTIVE: To examine the pharmacist's role in managing toothache pain from the patient's perspective. DESIGN: Cross-sectional study. SETTING: Maryland during April and May 2006. PARTICIPANTS: 5,556 low-income white, black, and Hispanic households were screened to identify 398 households with at least one adult who had experienced a toothache during the previous 12 months. INTERVENTION: Telephone screening followed by telephone interview concerning treatment sought for most recent toothache. MAIN OUTCOME MEASURE: Whether a pharmacist was consulted for toothache pain. RESULTS: Interviews were completed for 68.3% of eligible households. One of five respondents consulted a pharmacist regarding toothache pain. No differences were noted among demographic groups other than differences related to age. No association was observed between respondents asking for advice from pharmacists and the number of toothaches they experienced during the previous 10 years or the pain level of their most recent toothache; however, an association was seen between the duration of the most recent toothache and the degree to which the toothache interfered with daily activities. Approximately 90% of respondents adhered to pharmacist advice, while 55.7% reported that the advice helped "a lot." CONCLUSION: Pharmacists have an important role to play in alleviating toothache pain, especially among lower-income individuals without ready access to traditional dental services.

Toothache pain: a comparison of visits to physicians, emergency departments and dentists.

BACKGROUND: Researchers' understanding of the use of emergency departments (EDs) and physicians' offices for the treatment of toothaches is limited. The authors conducted a study to explore their use by low-income and minority adults in comparison with the use of traditional dental services. METHODS: Participants included low-income white, African-American and Hispanic adults who had experienced a toothache during the previous 12 months. A stratified random sample of 4,200 households in Maryland participated in a cross-sectional telephone survey. Trained survey staff completed interviews with someone in 272 (68.3 percent) of 398 eligible households. RESULTS: Only 8.7 percent of respondents contacted an ED for toothache pain relief, while 20.1 percent contacted physicians. The majority of respondents who contacted an ED (80.5 percent) or a physician (82.6 percent) also contacted a dentist. Contacts with a dentist were reported by 58.6 percent of respondents. The authors conducted tabular analyses using chi(2) tests of statistical significance (P < .05) and SUDAAN's multivariable logistic regression procedure (Research Triangle Institute, Research Triangle Park, N.C.) (P < .05). CONCLUSIONS: Respondents experiencing toothache pain ultimately sought definitive resolution of their pain from dentists while visiting EDs and physicians for temporary relief. Access to dentists' services was particularly problematic for Hispanics and was exacerbated by health literacy issues. CLINICAL IMPLICATIONS: The elimination of oral health disparities must involve consideration of cultural influences on minority populations, as well as the responsibilities of the dental profession.

Coping with toothache pain: a qualitative study of low-income persons and minorities.

OBJECTIVES: This study examined the behavioral impact of toothache pain as well as self-care strategies for pain relief among minority and low-income individuals. METHODS: Eight focus group sessions were conducted with 66 participants drawn from low-income non-Hispanic White, non-Hispanic Black, and Hispanic adults over the age of 20 who had experienced a toothache during the previous 12-month period and who had utilized self-care or care from a nondentist. RESULTS: Toothache pain was described as intense, throbbing, miserable, or unbearable. Focus group participants indicated that toothache pain affected their ability to perform normal activities, such as their job, housework, social activities, sleeping, talking, and eating, as well as making them depressed and affecting their social interactions. Numerous prescription and nonprescription medications as well as home remedies and self-care strategies were used for pain relief, although these were generally of limited and uncertain benefit. While receiving care at a dental office was the most preferable option for care, most participants reported multiple barriers, including the cost of dental care that resulted in long delays in seeking dental care. The main reason for eventually seeking dental care was the severity of the pain. CONCLUSIONS: Although removing financial barriers alone may not lead to preventive dental visits, it would facilitate more timely visits to dentists to treat toothache pain.

Impact of influenza immunization on medical expenditures among Medicare elderly, 1999-2003.

BACKGROUND: The impact of influenza immunization on expenditures for inpatient, outpatient, and professional services among elderly Medicare beneficiaries between 1999 and 2003 was examined. METHODS: Data were from independent annual survey samples of 175,000 beneficiaries. Response rates ranged from 64% to 71%. Survey data included beneficiaries' demographics, education, supplemental insurance, perceived health, and influenza vaccination. Baseline measures, derived from Medicare claims for the year prior to influenza season, included service utilization, comorbidities, influenza immunization, and health status. The outcome measure was medical expenditures for acute and chronic respiratory conditions (ACRCs) for each 33-week annual influenza season. RESULTS: Total expenditures for ACRCs were lower among the immunized population during all four seasons. The amount and statistical significance of the savings varied with the severity of the virus and the vaccine match to the prevalent influenza strains. During the 1999-2000 influenza season, which had the most severe virus and a close vaccine match, average costs for ACRCs were $88 lower among immunized beneficiaries than among nonimmunized beneficiaries (equivalent to a 3.06% savings). During the 2002-2003 season, which had a less severe virus but the highest vaccine match rate, average costs for ACRCs were $103 lower for immunized beneficiaries than for nonvaccinated beneficiaries (equivalent to a 3.12% savings). The relative reduction in ACRC expenditures among vaccinated beneficiaries is attributable to less frequent use of inpatient services. CONCLUSIONS: In addition to improving the health of older Americans, meeting the Healthy People 2010 influenza immunization goal of 90% among the elderly should also result in lower Medicare expenditures.

Impact of local adjuncts to scaling and root planing in periodontal disease therapy: a systematic review.

BACKGROUND: Chronic periodontitis affects many adults in the United States, some severely enough to threaten tooth loss. Of particular clinical importance is whether scaling and root planing (SRP) accompanied by a local adjunctive therapeutic agent improves outcomes over time compared to SRP alone. The adjunctive therapeutic agents investigated include: tetracycline, minocycline, metronidazole, a group of other antibiotics, chlorhexidine, and a group of antimicrobials. Primary outcomes considered are reductions in probing depth (PD) and gains in clinical attachment level (CAL). METHODS: RTI-UNC Evidence-Based Practice Center staff searched MEDLINE (1966 through December 2002) and EMBASE (through February 2002) to identify clinical trials published in English that 1) involved adults with chronic periodontitis but no serious comorbidities; 2) tested one or more chemical antimicrobial agents as an adjunct to SRP alone or with a placebo; 3) had a concurrent control group that received the same SRP as the treatment group; 4) reported outcomes for specified, fixed time periods; and 5) if multiple antimicrobials were tested, reported outcomes for each agent separately. We performed qualitative analyses and meta-analyses of PD and CAL effect sizes when the necessary data were available from at least three studies at 6-month follow-up. RESULTS: Among the locally administered adjunctive antimicrobials, the most positive results occurred for tetracycline, minocycline, metronidazole, and chlorhexidine. Adjunctive local therapy generally reduced PD levels. Differences between treatment and SRP-only groups in the baseline-to-follow-up period typically favored treatment groups but usually only modestly (e.g., from about 0.1 mm to nearly 0.5 mm) even when the differences were statistically significant. Effects for CAL gains were smaller and statistical significance less common. The marginal improvements in PD and CAL were a fraction of the improvement from SRP alone. CONCLUSIONS: Whether such improvements, even if statistically significant, are clinically meaningful remains a question. A substantial agenda of future research to address this and other issues (e.g., costs, patient-oriented outcomes) is suggested.

Disparities in immunizations among elderly Medicare beneficiaries, 2000 to 2002.

BACKGROUND: Research reveals that influenza and pneumococcal immunization rates among blacks, Asians, and Hispanics significantly trail those of whites. This 2003 study examines recent trends and disparities for influenza and pneumococcal immunizations among elderly, non-institutionalized Medicare beneficiaries. METHODS: National samples of approximately 179,000 Medicare fee-for-service beneficiaries were surveyed by mail and telephone each year from 2000 to 2002. Outcomes include self-reported influenza immunization in the previous year and receipt of a pneumococcal immunization ever. RESULTS: Influenza immunization dipped in 2001 (69%) and almost rebounded to its 2000 level (73%) in 2002 (72%). Very substantial racial and ethnic disparities in the receipt of this preventive service exist between non-Hispanic blacks and Hispanics relative to non-Hispanic whites. Pneumococcal immunization increased by 2% annually (61%, 63%, and 65%) for the same years. However, very substantial racial and ethnic disparities in the receipt of this preventive service also exist between non-Hispanic blacks, Asians/Pacific Islanders, and Hispanics relative to non-Hispanic whites. CONCLUSIONS: Younger, healthier, elderly persons must be encouraged to receive these immunizations to achieve the 2010 goal of 90% immunization. To reach that goal with no disparities, special efforts will be needed to target racial/ethnic minorities.

A systematic review of the performance of methods for identifying carious lesions.

This systematic review evaluates evidence describing histologically validated performance of methods for identifying carious lesions. A search identified 1,407 articles, of which 39 were included that described 126 assessment of visual, visual/tactile, radiographic (film and digital), fiber optic transillumination, electrical conductance, and laser fluorescence methods. A subsequent update added four studies contributing 10 assessments. The strength of the evidence was judged to be poor for all applications, signifying that the available information is insufficient to support generalizable estimates of the sensitivity and specificity of any given application of a diagnostic method. The literature is problematic with respect to complete reporting of methods, variations in histological validation methods, the small number of in vivo studies, selection of teeth, small numbers of examiners, and other factors threatening both internal and external validity. Future research must address these problems as well as expand the range of assessments to include primary teeth and root surfaces.

A systematic review of cardiovascular effects of epinephrine on hypertensive dental patients.

OBJECTIVE: A systematic review was conducted to identify any additional risks of adverse cardiovascular outcomes to hypertensive individuals represented by use of epinephrine-containing anesthetic solutions and epinephrine-impregnated retraction cords. STUDY DESIGN: Two searches identified 373 local anesthetic and 33 retraction cord reports; 6 local anesthetic reports met inclusion criteria. RESULTS: Use of epinephrine in uncontrolled hypertensive patients was associated with small, nonsignificant increases in systolic and diastolic blood pressure. No adverse outcomes were reported. Only one study examined effects of epinephrine on controlled hypertensive patients, in whom additional risks due to interactions with antihypertensive medication are possible. Available studies did not address effects of gingival retraction cord on hypertensive patients. CONCLUSIONS: Although the increased risk for adverse events among uncontrolled hypertensive patients was found to be low and the reported occurrence of adverse events in hypertensive patients associated with the use of epinephrine in local anesthetics was minimal, the quantity and quality of the pertinent literature is problematic.

A systematic review of complication risks for HIV-positive patients undergoing invasive dental procedures.

BACKGROUND: This systematic literature review determined the strength of evidence regarding whether patients with human immunodeficiency virus, or HIV, are at higher risk of developing complications from invasive oral procedures than similar patients without HIV. TYPES OF STUDIES REVIEWED: MEDLINE and EMBASE searches of the English literature from the early 1980s through April 2000 yielded five articles meeting the inclusion and exclusion criteria: original research, concurrent treatment of HIV-positive and HIV-negative subjects, presence of complications (for example, local or systemic infection, bleeding, alveolitis, delayed healing) resulting from extractions, orthognathic surgery, periodontal therapy, endodontic therapy, placement of dental implants, prophylaxis, or scaling and root planing. RESULTS: The authors found no studies involving orthognathic surgery, periodontal therapy, dental implants, prophylaxis, or scaling and root planing, and only one study reporting few immediate endodontic therapeutic complications. Thus, the evidence is insufficient with respect to any additional risk associated with these procedures among people with HIV/AIDS. Because of the few studies, low overall complication rates and variability in results from different analytic approaches, the authors consider the evidence to be too poor to rule in or out a meaningful relationship between HIV status and complications from tooth extractions. CLINICAL IMPLICATIONS: Limited published scientific evidence is available to guide clinicians in regard to possible increased risks of invasive oral procedures associated with the HIV status of the patient.
