Perspectives of San Juan healthcare practitioners on the detection deficit in oral premalignant and early cancers in Puerto Rico: a qualitative research study

Diagnostic approach used by US general dental practitioners following discovery of oral lesions suspicious for malignancy/premalignancy: findings from the National Dental Practice-Based Research Network

OBJECTIVE

Oral cancer examinations seek to clinically identify early oral cancers and discover premalignancies prior to their progression to invasive cancer.

METHOD AND MATERIALS

A cross-sectional study was conducted between April and August 2017 to explore and quantify the diagnostic approach used by United States (US) general dental practitioners following discovery of an oral lesion suspicious for malignancy/premalignancy. US licensed general dental practitioners who were clinically active members of the US National Dental Practice-Based Research Network were eligible to participate. Data for analysis were obtained via two questionnaires.

RESULTS

The majority of participants were males, practiced full-time, had a suburban primary practice, were born during the 1950s, and graduated dental school in the 1980s or 2000s. After identifying an oral lesion suspicious for premalignancy/malignancy, the next action of most general dental practitioner respondents (65.4%) was to refer the patient for consultation/biopsy. Most general dental practitioners (87.2%) referred to an oral and maxillofacial surgeon; 22% of general dental practitioners reported personally biopsying suspicious lesions. There was a relatively weak association between completing an Advanced Education in General Dentistry or General Practice Residency and subsequently personally performing biopsies on patients with oral lesions suspicious for malignancy/premalignancy (OR 1.33, P = .06). Most written referrals took place electronically and often included information, including lesion location (87.0%), lesion sign/symptoms (85.3%), lesion history (83.9%), radiographs (59.3%), medical history (50.6%), dental history (48.8%), and photographs (42.4%). When a referral biopsy was performed, referring clinicians were most frequently informed of the findings via a written report (96.7%, when positive for malignancy/premalignancy, and 95.4% when negative).

CONCLUSION

A snapshot is presented of current actions taken by US general dental practitioners following the discovery of oral abnormalities suspicious for premalignancy/malignancy.

General dentists' knowledge, perceptions, and practices regarding oral potentially malignant disorders and oral cancer in Indonesia

INTRODUCTION

The most effective means for reducing oral cancer (OC) mortality is by preventing late-stage disease. Early diagnosis can be improved by increasing awareness among healthcare providers, specifically general dental practitioners (GDP). Therefore, our study aimed to assess GDPs' knowledge of OC risk factors and perceived competence in performing conventional oral examination (COE) in routine dental practice.

MATERIAL AND METHODS

This was a cross-sectional study conducted in five provinces of Indonesia, namely: Aceh, Banda Aceh (BA); Bandung, West Java (WJ); special district Jakarta (JKT), JKT; Pontianak, West Kalimantan (WK); and Sorong, West Papua (WP). The local Dental Association or Faculty of Dentistry invited the GDPs to attend an education program and complete the survey.

RESULTS

One hundred seventy-seven GDPs completed the survey (WJ, n = 63; BA, n = 44, JKT, n = 27; WP, n = 23; and WP, n = 20). A large proportion (164 out of 177, 92.66%) of GDPs felt they had received insufficient training to equip them to diagnose OC and as many as 22.6% (n = 40) did not refer to specialists when they found suspicious mucosal lesions. Notwithstanding the significant regional variations, the majority of Indonesian GDPs self-reported inadequate knowledge and awareness of OC and scarce confidence in performing COE.

CONCLUSION

GDP knowledge of OC risk factors and COE is key to improving early diagnosis of OC at a community level. Therefore, it is suggested that the lack of knowledge and confidence of GDPs reported here should be addressed through the national dental curriculum in Indonesia.

Continuing education activities improve dentists' self-efficacy to manage oral mucosal lesions and oral cancer

OBJECTIVES

This cross-sectional study aims to evaluate whether Continuing Education Activities (CEA) influence dentists' behaviour in relation to oral lesions. The secondary aim is to assess the association between dentists' perception of learning adequacy and self-efficacy for oral mucosal lesion management.

METHODS

A self-administered online questionnaire was conducted on dentists working at the public health system of Rio Grande do Sul State, Brazil. The questionnaire included questions pertaining to perception of adequacy for oral diagnosis classes upon graduation, participation in oral cancer CEA and self-efficacy in managing oral mucosal lesions.

RESULTS

221 dentists from 91 municipalities answered the questionnaire. Most participants were female (71.5%) with a mean age of 38.3 years. Perception of learning as adequate during undergraduate coursework was associated with self-efficacy to diagnose, biopsy, and treat oral mucosal lesions (P < .05, Chi-squared test). However, 83.3% of dentists considered the time devoted to these topics prior to graduation insufficient. The frequency of oral lesion detection was related to self-efficacy to treat oral lesions and detecting oral cancer (P < .05, Chi-squared test). Among dentists who detected oral lesions frequently, 88.9% had attended CEA, whereas 11.1% of them had never attended these activities.

CONCLUSIONS

CEA may improve awareness and efficacy of primary healthcare professional's detection of oral cancer.

Knowledge, attitudes and practices of general medical practitioners in developed countries regarding oral cancer: an integrative review

BACKGROUND

Oral cancer is a public health concern and is widespread in developing countries, particularly in South Asia. However, oral cancer cases are also rising in developed nations due to various factors, including smoking, viruses and increased migration from South Asia. In this context, the role of general medical practitioners (GPs) in identifying oral cancer is becoming increasingly important and, while some studies have explored their perspective about oral cancer, a synthesis of these results has not been undertaken.

OBJECTIVE

The objective of this integrative review is to synthesize existing evidence regarding oral cancer-related knowledge, attitudes and practices of GPs in developed countries.

METHODS

Four electronic databases were searched to identify studies focussing on the objective of this review. The inclusion criteria were: peer-reviewed English language publications; studies conducted in developed countries involving GPs; explored at least one study outcome (knowledge/attitudes/practices). No restrictions were placed on the publication date.

RESULTS

A total of 21 studies involving 3409 GPs were reviewed. Most studies revealed limited knowledge of GPs about emerging risk factors, such as betel nut chewing (0.8-50%). Significant variation (7-70%) was evident in routine oral examination practices of GPs. Most GPs felt unsure about diagnosing oral cancer and many (38-94%) raised the need for further education. No study explored the specific relevance of GPs' practices concerning South Asian immigrants.

CONCLUSION

This review suggests the need for educational programs to enhance GPs' knowledge regarding oral cancer. Further research exploring oral cancer-related practices of GPs caring for South Asian immigrants is warranted.

Factors associated with late stage at diagnosis among Puerto Rico's government health plan colorectal cancer patients: a cross-sectional study

Background

Late stage at diagnosis of cancer is considered a key predictor factor for a lower survival rate. Knowing and understanding the barriers to an early diagnosis of colorectal cancer is critical in the fight to reduce the social and economic burden caused by cancer in Puerto Rico. This study evaluates factors associated to colorectal cancer stage at diagnosis among Puerto Rico’s Government Health Plan (GHP) patients.

Methods

We conducted a cross-sectional study based on a secondary data analysis using information from the Puerto Rico Central Cancer Registry (PRCCR) and the Puerto Rico Health Insurance Administration (PRHIA). Logistic regression models were used to estimate the unadjusted odds ratio (ORs) and adjusted odds ratio (AORs), and their 95 % confidence intervals (CIs). Colorectal cancer cases diagnosed between January 1, 2012 and December 31, 2012, among persons 50 to 64 years of age, participants of the GHP and with a cancer diagnosis reported to the PRCCR were included in the study.

Results

There were 68 (35.79 %) colorectal cancer patients diagnosed at early stage while 122 (64.21 %) where diagnosed at late stage. In the multivariate analysis having a diagnostic delay of more than 59 days (AOR 2.94, 95 % CI: 1.32 to 6.52) and having the first visit through the emergency room (AOR 3.48, 95 % CI: 1.60 to 7.60) were strong predictors of being diagnosed with colorectal cancer at a late stage.

Conclusions

These results are relevant to understand the factors that influence the outcomes of colorectal cancer patients in the GHP. Therefore, it is important to continue developing studies to understand the Government Health Plan patient’s pathways to a cancer diagnosis, in order to promote assertive decisions to improve patient outcomes.

Screening and referral of oral mucosal pathology: a check-up of Australian dentists

BACKGROUND

Oral squamous cell carcinomas and potentially malignant oral disorders can be detected early by visually inspecting the oral soft tissues. This study aimed to determine Australian dentists' opinions and practices regarding oral mucosal screening, referral and oral cancer prevention.

METHODS

Nine hundred and ninety-nine randomly selected general dentists were mailed a questionnaire. The questionnaire queried practitioners' opinions and perceptions of oral mucosal screening, their referral practices and their beliefs regarding detection and prevention of oral cancer.

RESULTS

A total of n=640 individuals responded, yielding a response rate of 70.2%. Most Australian dentists reported to routinely perform oral mucosal screening. Lack of training, confidence, time and financial incentives were seen as barriers to performing mucosal screening to at least some degree by participants in this study. Most dentists manage referrals for oral mucosal pathology appropriately; however, only about half believe in following up with referred patients. Only half of dentists surveyed believed that they could influence a patient to quit smoking.

CONCLUSIONS

Australian dentists place importance on oral mucosal screening. Some changes to dental education and training could be made to further improve confidence and ability of dentists in detecting and referring oral mucosal pathology.

Increasing opportunistic oral cancer screening examinations: findings from focus groups with general dentists in Puerto Rico

This study aims to identify educational and training modalities that dentists in Puerto Rico (PR) believe will increase the quality and quantity of opportunistic oral cancer screening examinations (OCS) in dental offices on the island. The study was conducted in three phases: a systematic search of relevant literature, an expert review and consensus panel, and focus groups (FG) involving PR general dentists. To increase OCS by dentists in PR, the FG participants proposed a small group, hands-on OCS training, an integrated oral cancer course, and readily available videos, photographs, and computer simulations to further demonstrate OCS performance and facilitate differential diagnosis. OCS training requirements for licensure and re-licensure, improving OCS dentist-patient communication skills, and establishment of an oral lesion referral center were also viewed favorably. In conclusion, general dentists in our FGs believed the quality and quantity of OCS in Puerto Rico can be increased through the application of specific continuing education and training modalities.

Oral mucosal screening and referral attitudes of Australian oral health therapists and dental hygienists in Queensland

OBJECTIVES

The aim of this study was to describe oral mucosal screening and referral attitudes of Australian oral health therapists (OHTs) and dental hygienists (DHs).

METHODS

Questionnaires were distributed to participants who attended dental hygiene courses run in both regional and metropolitan Queensland.

RESULTS

One hundred and two participants comprised 58 OHTs and 44 DHs, with a mean of 8.9 years since graduation. Thirty-four participants worked in regional locations, while 68 were from metropolitan areas. 97% of participants agreed that mucosal screening should be performed for all new and recall patients, while a minority (5%) agreed that patients will detect an oral mucosal change themselves. The majority (77%) agreed that oral cancer would be encountered in their practising career. Most participants (81%) felt comfortable discussing the presence of a suspicious lesion with patients and 88% agreed that it was their role to screen. In terms of barriers to oral cancer screening, lack of training was seen as the most prevalent barrier (56%) followed by lack of confidence (51%). Lack of time was seen as the third most prevalent barrier (40%), and lack of financial incentives was the least prevalent barrier (16%).

CONCLUSIONS

Oral health therapists and DHs understand the importance of oral mucosal screening and are likely to be alert to oral mucosal changes. While lack of time and financial incentives was perceived to be impediments to mucosal screening, lack of confidence and training was the most prevalent barriers. This issue should be addressed through implementation of effective continuing education courses targeting oral cancer screening and referral practices.

Effects of type of health insurance coverage on colorectal cancer survival in Puerto Rico: a population-based study

Colorectal cancer represents a major health problem and an important economic burden in Puerto Rico. In the 1990's, the Commonwealth of Puerto Rico implemented a health care reform through the privatization of the public health system. The goal was to ensure access to health services, eliminate disparities for medically indigent citizens and provide special coverage for high-risk conditions such as cancer. This study estimates the 5-year relative survival rate of colorectal cancer and the relative excess risk of death in Puerto Rico for 2004-2005, by type of health insurance coverage; Government Health Plan vs. Non-Government Health Plan. Colorectal cancer in advanced stages was more common in Government Health Plan patients compared with Non-Government Health Plan patients (44.29% vs. 40.24 had regional extent and 13.58% versus 10.42% had distant involvement, respectively). Government Health Plan patients in the 50-64 (RR = 6.59; CI: 2.85-15.24) and ≥65 (RR = 2.4; CI: 1.72-4.04) age-groups had the greater excess risk of death compared with Non-Government Health Plan patients. Further studies evaluating the interplay of access to health services and the barriers affecting the Government Health Plan population are warranted.
