Opinions about oral cancer prevention and early detection among dentists practising along the Texas-Mexico border

OBJECTIVES: The purpose of this study was to assess dentists' opinions about oral cancer (OC) prevention and early detection. METHODS: Data were collected by a self-administered mail questionnaire sent to all 398 registered dentists practising along the Texas-Mexico border. RESULTS: The effective response rate to the survey was 40%. While 90% of respondents agreed that oral cancer examinations (OCE) should be provided annually for patients 40 years of age and older, only 59% of respondents believed their OC knowledge was current. While 99% agreed that dentists were qualified to perform OCE, only 54 and 68% respectively, agreed that dental hygienists and physicians were similarly qualified. Dentists who rated their undergraduate OC training favorably (OR = 2.68, 1.23-5.81, P = 0.011), had attended their last oral cancer continuing education (OCCE) course within the past 5 years (OR = 2.46, 1.25-4.86, P = 0.009), and those who performed OCE on all patients 40 years and older (OR = 2.64, 1.32-5.26, P = 0.005), were more likely to agree their OC knowledge was current. CONCLUSIONS: Respondents expressed diverse opinions about OC prevention and early detection. Positive opinion on currency of OC knowledge was associated with performance of OCE. Results indicate a need for OCCE targeting the study population as well as increased emphasis on OC curriculum in dental schools.     

Knowledge of oral cancer and screening practices of primary care providers at Federally Qualified Health Centers

OBJECTIVES: Primary care providers (PCPs) who worked in Federally-Qualified Health Centers (FQHC) in Michigan were surveyed to assess their knowledge level and practices related to screening and preventing oral cancer. METHODS: A questionnaire was developed with the assistance of dental and medical experts, and revised through focus groups. The questionnaire included one case scenario describing a suspicious oral lesion in a 55-year old female patient, followed by questions assessing PCPs' knowledge level, attitude, opinion, and screening practices for oral cancer. This mail survey was conducted in 2003. RESULTS: Survey response rate was 56.4%. Over 70% of the respondents reported that they screen patients for oral cancer during a routine physical examination. Forty-four percent of PCPs had high knowledge level, based on the scenario questions. Those who had high knowledge level were more likely to be physicians, males, and more likely to perform screening for oral cancer than those with low knowledge level. There was no difference in age and race/ethnicity between high and low knowledge groups. Perceived barriers included (1) lack of education; (2) lack of specialists to refer patients; and (3) lack of reimbursement. CONCLUSIONS: The majority of PCPs in this survey had positive attitudes about performing screening for oral cancer. To involve PCPs in screening for oral cancer, oral health programs should focus on providing up-to-date education, setting up a referral system, and providing proper reimbursement.     

Dentists and oral cancer prevention in the UK: opinions, attitudes and practices to screening for mucosal lesions and to counselling patients on tobacco and alcohol use: baseline data from 1991

OBJECTIVE: To investigate the opinions, attitudes and practices towards oral cancer prevention among UK dentists as a baseline from which to measure the need for continuing education efforts in this area. DESIGN AND METHOD: Postal questionnaire survey carried out in August 1991. A questionnaire with 13 test items was piloted at continuing education courses then distributed to all subscribers of the British Dental Journal with a postage paid return envelope. The aspects inquired into were recent attempts by dentists at updating their knowledge on oral cancer, their practical approaches to screening for oral mucosal diseases and follow-up actions after oral screening, their questions to patients regarding the major risk factors for oral cancer, their efforts towards behavioural counselling for patients and any constraints felt or experienced in this regard. RESULTS: The questionnaire was circulated to 15,836 dentists. The response rate of 16% was poor but due to the many dentists circulated, 2519 responses were available for analysis. This large sample, though presumptively biased towards those interested in professional matters, showed an encouraging 84% claiming to perform screening of the oral mucosa routinely. Among these, 74% reported referral of screen detected cases to a hospital for further attention and only 4% would adopt a wait and see policy. Disturbingly, half of the respondents did not enquire about risk habits related to oral cancer and, among the other half who claimed to make such enquiries, only 30% routinely provided brief health education advice concerning these. Seventy-one percent agreed that giving advice against tobacco use is desirable but major constraints were identified, notably a lack of training, and frustration regarding patient compliance. There was even greater reluctance on the part of the respondents to enquire into the alcohol use of their patients and to provide advice on alcohol moderation. CONCLUSIONS: Most of this large but unrepresentative sample of UK dentists were carrying out screening of the oral mucosa as a part of their prevention activities in 1991. However, the survey indicated a considerable need for improvement in the manner and extent of provision of health advice in respect of the major risk factors for oral cancer: such a substantial need amongst the presumptively better motivated implies that the need amongst the practitioner population at large is even greater.

Evaluation of screening for oral cancer and precancer in a company headquarters

Abstract Oral cancer and precancer appear to fulfil many of the criteria for a disease suitable for mass screening. Several commercial organisations in the UK have introduced screening for their employees. One program has been formally evaluated over the course of 1 yr. Of 553 company headquarters staff aged ≥40 yr, 292 (53%) responded to the well-publicised screening invitation and received a simple clinical examination of the oral mucosa from one of two company dentists. In addition, 17 staff were screened from a separate company work-site. After screening, subjects were examined independently by an oral medicine specialist with access to the relevant diagnostic aids. The dentists' screening decisions were validated against the specialist's definitive diagnoses (the‘gold standard'). The true prevalence of subjects with lesions diagnosed as positive (white patch, red patch or ulcer of greater than 2 weeks' duration) was 17 (5.5%). Overall, sensitivity was 0.71 and specificity, 0.99. The compliance rate to screening among headquarters subjects in seven occupational categories did not differ significantly from the occupational profile for all headquarters personnel. Estimates of relative risk of a positive diagnosis were calculated by logistic regression for five independent variables: gender, age, moderate smoking, heavy smoking, and smoking combined with greater than low risk alcohol consumption. Only heavy smoking (≥20 cigarettes per day) produced a significant odds ratio (3.43, P < 0.05).     

The opinions and attitudes of dental school academic staff towards oral healthcare education for older adults

The term ‘oral health care for older adults’ has various interpretations, and its meaning is not clear among dental school academic staff. Additionally, there are no theoretical or practical stand‐alone courses on oral health care for older adults in Japanese dental schools. To improve oral health care education, we investigated the opinions and attitudes toward oral health care education for older adults among academic staff in dental schools. Data were collected in seven dental schools from May to September 2013 via an online questionnaire survey. Five‐hundred‐fifty‐eight academics (428 male, 130 female) participated (response rate 57%). The average number of years since they had completed a university degree was 20.2 (SD 10.2) years. The majority (Over 90%) of participants perceived that oral health care should be provided in nursing facilities, hospitals, and at home. Its treatments and instructions should include, not only methods of keeping good oral hygiene, but also improvement of oral function such as swallowing training and salivary glands massage. The majority (84.2%) suggested oral health care education should be combined as a one‐credit, stand‐alone course. Findings indicate that dental academics have an understanding the need for a course in oral health care for older adults. Participants supported the need for further development of education in oral health care for older adults’ in Japan, as a separate course on its own right. However there were some different views about content by teaching field. The need for a national core program for teaching oral health care education was suggested.     

Terminal care for oral cancer patients in hospital dentistry and oral and maxillofacial surgery at a local area

A sequential study concerning suicide of patients with oral cancer, notification of oral cancer, terminal care of patients with oral cancer at home, etc. has been performed in our department. As part of the study, a possible role of hospital dentistry and oral and maxillofacial surgery at a local area was examined recently with reference to the terminal alleviating care provided to three patients with oral cancer at Joetsu General Hospital. The result was as follows: It is natural that most patients want to die at home in the presence of their family. In order to fulfill such a desire, it is considered necessary that a hospital dentistry and oral and maxillofacial surgery must handle terminal alleviating care. However, many problems still remain in managing patients with terminal cancer in a hospital dentistry. But also a cooperation with a university hospital and cooperation with the department of dentistry in other hospitals, education activity concerning oral cancer at local medical treatment including within hospital care, effective utilization of local nursing station, and examination of the home care system, are considered essential.

     

Influence of patient,visit, and oral health factors on dental service provision

OBJECTIVES: Service provision should reflect the oral health of the patient. However, patient and visit factors may influence service patterns and the appropriateness of care delivered. The aim of this study was to examine factors associated with variation in dental services and to assess whether variation by patient and visit characteristics persisted after controlling for oral health status. METHODS: A random sample of Australian dentists was surveyed during 1997-98 (response rate = 60.3%). Private general practitioners (n = 345) provided data on service provision, as well as patient, visit and oral health variables from a log of a typical clinical day (n = 4,115 patients). Multivariate Poisson regression models were run for eight service areas (e.g., diagnostic, preventive, and restorative). RESULTS: Significant effects (P < .05) were observed for oral health factors in all eight models, visit factors in all eight models, patient demographics in four models, dental knowledge/behavior in one model, and area-based socioeconomic status in one model. CONCLUSIONS: After controlling for oral health, visit characteristics persisted as significant predictors of services, with nonemergency visits, insurance, and capital city location associated with more favorable service mix patterns. Higher socioeconomic status areas and payment scale ratings also were associated with a better service pattern in particular service areas. These findings show that a wide range of factors, in addition to oral health, contribute to variation in service provision.     

Evaluation of a multifaceted social marketing campaign to increase awareness of and screening for oral cancer in African Americans

Jedele JM, Ismail AI. Evaluation of a multifaceted social marketing campaign to increase awareness of and screening for oral cancer in African Americans. Community Dent Oral Epidemiol 2010; 38: 371–382. © 2010 John Wiley & Sons A/S Abstract – Objectives: A 2‐year social marketing media campaign and community education activities were organized to promote screening for oral cancer in a high‐risk population in Detroit/Wayne County, Michigan. Long‐term goals of the campaign were to reduce the oral cancer death rate, increase the proportion of oral cancers detected at an early stage, and increase the proportion of adults who report having been screened. The intermediate goals of the campaign were to increase awareness of oral cancer and of oral cancer screening. This article presents outcomes related to the intermediate goals of the campaign. Methods: The intermediate goals of the campaign were assessed by the number of calls to a toll‐free hotline, which media venues led to calls, number of screenings conducted by the free screening clinic, number of precancers and cancers detected, and the number of sessions conducted, organizations involved, and persons participating in the community education program. The costs per screened case and cancers detected were also evaluated. The media campaign promoted screening using billboards, radio and newspaper ads, and a toll‐free hotline. Culturally relevant messages were developed collaboratively with focus groups representing the target audience. Billboards were placed in highly visible locations around Detroit, Michigan. Sixty‐second messages on the impact of oral cancer and that screening is ‘painless and free’ were aired on radio stations popular with the target audience. Ads displaying the hotline were placed in two local newspapers. Callers to the hotline were scheduled for a free screening with a clinic operated by the project. Referral to an oral surgeon was scheduled if a suspicious lesion was found. Free education sessions were also conducted with community‐based organizations. Costs associated with the campaign and hotline were totaled, and the cost per screening and cancer detected were calculated. Results: During the campaign, 1327 radio spots aired; 42 billboards were displayed; two newspaper ads were printed; and 242 education sessions were conducted. The hotline received 1783 calls. The majority of callers reported that their call was prompted by a radio ad (57%). The clinic screened 1020 adults and referred 78 for further examination. Three cancers, two precancers, and 12 benign tumors were detected. The total cost associated with the campaign and toll‐free hotline was $795,898. Conclusions: A multifaceted social marketing campaign including radio ads, billboards, and education sessions can effectively target a high‐risk population and that given an outlet could result in a significant number of people getting screened at a relatively low cost.     

Oral cancer screening: Practices, knowledge, and opinions of dentists working in Ohio nursing homes

The state of oral health of nursing homes residents is less than satisfactory. The oral health care in nursing homes is also deficient, therefore it is likely that oral cancer (OC) screening of residents will be inadequate. The purpose of this cross-sectional study was to determine OC screening practices, knowledge, and opinions of dentists working in nursing homes throughout Ohio. A 28-item pretested questionnaire was mailed to 75 dentists who were serving 606 nursing homes.
The response rate was 49%. The main outcome measures of interest included: OC screening practices of the Ohio dentists, their knowledge of OC detection, and their opinions regarding OC screening competency. Age was found to be a significant factor, with younger dentists being more likely to have higher knowledge scores after adjusting for all other covariates.
