Practitioner Participation in National Dental Practice-based Research Network (PBRN) Studies: 12-Year Results

Practice-based research in dentistry: Exploring methodologies, benefits, and challenges

BACKGROUND

Practice-Based Research Network (PBRN) studies typically assess the effectiveness of clinical interventions in settings that match real-world conditions. Dental PBRNs have the capacity to amass, identify, and analyze vast amounts of data from patient populations that include diverse racial, ethnic, socio-economic, and geographic backgrounds. These dental studies encompass a broad spectrum of healthcare aspects, including prevention, diagnosis, symptom and disease treatment, quality enhancement, and care coordination.

METHODS

An extensive range of research methodologies can be employed within dental PBRNs to investigate these topics, including randomized controlled trials. Dental PBRNs have evolved from primarily focusing on case observations to leveraging advanced network infrastructure and collaborating across multiple regional and national sites. In addition to producing numerous high-impact peer-reviewed publications, study results have led to improved clinical care. However, PBRNs encounter challenges, such as the sustainability of research capacity (relying heavily on ongoing support from funding agencies), diverse research cultures, and an imperative to design studies that are both feasible and relevant to everyday clinical practice. Recognizing the pivotal role of real-world evidence, it is important to have sustained investment in dental PBRN infrastructure and feasible opportunities for practitioners to participate in network activities nationwide.

CONCLUSION

Practice-Based Research Network studies capitalize on an important research context within which to investigate a range of clinical topics that can employ multiple research methodologies. However, sustaining productive networks requires strategic effort, ongoing financial support, and customized organizational skills.

Participation Rates in 11 National Dental Practice-Based Research Network Surveys 2014-2022

Surveys of health professionals typically have low response rates, which have decreased in recent years. We report on the methods used, participation rates, and study time for 11 national questionnaire studies of dentists conducted from 2014-2022. Participation rates decreased (87%-25%). Concurrent with this decrease was a decrease in the intensity with which the practitioners were recruited. Participation rates were higher when postal mail invitation and paper options were used (84% vs. 58%, p < .001). Completion rates were nearly twice as high in studies that recruited in waves than those that did not (61% vs. 35%, p = .003). Study time varied from 2.6 to 28.4 weeks. Study time was longest when postal mail and completion on paper were used (26.0 vs. 11.3 weeks, p = .01). Among studies using only online methods, study time was longer when invitations were staggered than when all invitations went out in one bolus (means 12.0 and 5.2, p = .04). Study time was positively correlated with participation rates (Spearman r = .80, p = .005). General dentists participated at an average of 12% higher rates than specialists. Recruitment methodology, such as recruiting in waves or stages, should be considered when designing surveys.

Recruitment strategies and retention rates for five National Dental PBRN studies

Background

We describe a retrospective assessment of practitioner and patient recruitment strategies, patient retention strategies, and rates for five clinical studies conducted in the National Dental Practice-Based Research Network between 2012 and 2019, and practitioner and patient characteristics associated with retention.

Methods

Similar recruitment strategies were adopted in the studies. The characteristics of the practitioners and patients are described. The proportion of patients who either attended a follow-up (FU) assessment or completed an online assessment was calculated. For studies with multiple FU visits or questionnaire assessments, rates for completing each FU were calculated, as were the rates for completing any and for completing all FU assessments. The associations of practitioner and patient characteristics with all clinic FU visits, and with the completion of all assessments for a study were ascertained.

Results

Overall, 591 practitioners and 12,159 patients were included. FU rates by patients for any assessment varied from 91% to 96.5%, and rates for participating in all assessments ranged from 68% to 87%. The mean total number of patients each practitioner recruited was 21 (sd = 15); the mean number per study was 13 (sd = 7). For practitioners, practice type and patient enrollment were associated with greater clinic retention, while only race was associated with their patients completing post-visit online assessments. For patients, age was associated with clinic retention, while female gender, age, race, and education were all associated with greater completion of post-visit online assessments.

Conclusion

The Network efficiently recruited practitioners and patients and achieved high patient retention rates for the five studies.

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.

Patient and dentist perspectives on collecting patient reported outcomes after painful dental procedures in the National Dental PBRN

BACKGROUND

Dental Patient Reported Outcomes (PROs) relate to a dental patient's subjective experience of their oral health. How practitioners and patients value PROs influences their successful use in practice.

METHODS

Semi-structured interviews were conducted with 22 practitioners and 32 patients who provided feedback on using a mobile health (mHealth) platform to collect the pain experience after dental procedures. A themes analysis was conducted to identify implementation barriers and facilitators.

RESULTS

Five themes were uncovered: (1) Sense of Better Care. (2) Tailored Follow-up based on the dental procedure and patient's pain experience. (3) Effective Messaging and Alerts. (4) Usable Digital Platform. (5) Routine mHealth Integration.

CONCLUSION

Frequent automated and preferably tailored follow-up messages using an mHealth platform provided a positive care experience for patients, while providers felt it saved them time and effort. Patients thought that the mHealth questionnaires were well-developed and of appropriate length. The mHealth platform itself was perceived as user-friendly by users, and most would like to continue using it.

PRACTICAL IMPLICATIONS

Patients are prepared to use mobile phones to report their pain experience after dental procedures. Practitioners will be able to close the post-operative communication gap with their patients, with little interruption of their workflow.

Characteristics of dentists in the National Dental Practice-Based Research Network

OBJECTIVES

Our aims are to describe the characteristics of dentists, members of the US National Dental practice-based research network (PBRN) in the United States, and determine how often these dentists provide specific dental procedures.

METHODS

Dentists completed a questionnaire when they enrolled in the Network about their demographic and training characteristics and characteristics of their practices and patients. Dentists also reported the frequency of providing specific dental procedures. Data were analyzed using descriptive statistics.

RESULTS

Of 4,483 dentists in active clinical practice, 34% identified as females, 70% as white, and 73% as general dentists. Most dentists practiced in large metropolitan areas (87%) and in solo or small practices (72%). On average, they reported about one-half of their patients were children or older adults, a third were from historically underrepresented racial and ethnic groups, and one-quarter were covered by public insurance. Most dentists routinely performed restorations and fixed prosthetics (78%), extractions (59%), removable (44%) and implant (40%) prosthetics, and endodontics on incisor and premolar teeth (44%).

CONCLUSIONS

Dentists participating in the National Dental PBRN have much in common with dentists at large. The network has a broad representation of dentists, practice types, patient populations, and treatments offered, including diversity regarding race/ethnicity, gender, insurance, and geography of its practitioners and patients.

CLINICAL SIGNIFICANCE

Characteristics of National Dental PBRN dentists suggest that a broad range of dentists is interested in participating in national-level research studies, thereby enabling an array of clinical study settings and topics that can optimize the generalizability of study findings.

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

Background

The COVID-19 pandemic highlights the need for practitioners to enhance workflows to increase safety and mitigate risk. As dental practice creates a highly aerosolized environment, pre-visit testing for SARS-CoV-2 has the potential to be an effective mitigation strategy to minimize disease transmission in dental offices. The Pragmatic Return to Effective Dental Infection Control through Testing (PREDICT) Feasibility Study examined the potential, logistics, and impact related to laboratory-based PCR viral testing and point-of-care (POC) antigen testing.

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. For this feasibility study, analysis was limited to descriptive measures. Median and interquartile ranges were reported for Likert scale responses and mean and standard deviation for continuous variables.

Results

Forty-one of forty-three consented patients and twenty-eight of twenty-nine DHCWs completed the protocol. Descriptive statistics calculations including median and interquartile ranges revealed (1) saliva, tongue epithelial cells and nasal swabs were the most desirable specimens for testing for groups (2) both LAB and POC protocols took similar amounts of total time to complete the full testing protocol and (3) DHCWs and patients reported feeling more comfortable when both groups were tested.

Conclusions

This feasibility study suggests that pre-visit SARS-CoV-2 testing can be effectively implemented into dental practice workflows and positively impact perception of safety for DHCWs and patients, though a larger scale, network study is necessary for generalizability of results. As new virulent infectious diseases continue to 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.

Dental practitioner approaches to bruxism: Preliminary findings from the national dental practice-based research network

OBJECTIVE

Bruxism is a repetitive masticatory muscle activity. This study investigates dental practitioners' approaches to bruxism assessment and treatment in practices.

METHODS

A brief 5 question questionnaire ("Quick Poll") on bruxism was conducted.

RESULTS

A total of 397 practitioners responded. More than half (55%) initiated treatment for bruxism on one to three patients per month. The majority believed that stress (97%) and sleep patterns (82%) affected bruxism in their patients. Interestingly, 96% offered an occlusal guard/appliance and 46% made occlusal adjustments.

CONCLUSION

This study highlights inconsistencies in practitioner approaches to bruxism assessment and management in clinical settings, suggesting gaps in practitioner knowledge evidenced by the varied responses.

Study protocol: understanding pain after dental procedures, an observational study within the National Dental PBRN

BACKGROUND

Patient-reported outcome measures provide an essential perspective on the quality of health care provided. However, how data are collected, how providers value and make sense of the data, and, ultimately, use the data to create meaningful impact all influence the success of using patient-reported outcomes.

OBJECTIVES

The primary objective is to assess post-operative pain experiences by dental procedure type through 21 days post-procedure as reported by patients following dental procedures and assess patients' satisfaction with pain management following dental surgical procedures. Secondary objectives are to: 1) assess post-operative pain management strategies 1 week following dental surgical procedures, as recommended by practitioners and reported by patients, and 2) evaluate practitioner and patient acceptance of the FollowApp.Care post visit patient monitoring technology (FollowApp.Care). We will evaluate FollowApp.Care usage, perceived usefulness, ease of use, and impact on clinical workload.

DESIGN AND METHODS

We describe the protocol for an observational study involving the use of the FollowApp.Care platform, an innovative mobile application that collects dental patients' assessments of their post-operative symptoms (e.g., pain). The study will be conducted in collaboration with the National Dental Practice-based Research Network, a collective Network of dental practices that include private and group practices, public health clinics, community health centers and Federal Qualified Health Centers, academic institutional settings, and special patient populations. We will recruit a minimum of 150 and up to 215 dental providers and up to 3147 patients who will receive push notifications through text messages FollowApp.Care on their mobile phones at designated time intervals following dental procedures. This innovative approach of implementing an existing and tested mobile health system technology into the real-world dental office setting will actively track pain and other complications following dental procedures. Through patients' use of their mobile phones, we expect to promptly and precisely identify specific pain levels and other issues after surgical dental procedures. The study's primary outcome will be the patients' reported pain experiences. Secondary outcomes include pain management strategies and medications implemented by the patient and provider and perceptions of usefulness and ease of use by patients and providers.

Structure, function, and productivity from the National Dental Practice-Based Research Network

Introduction:

Following inception in 2005 as a multiregional practice-based research network (PBRN), the “National Dental PBRN” expanded nationwide in 2012, and in 2019 implemented additional organizational changes. The objectives are to: (1) describe the new structure and function of the network; and (2) quantify its scientific productivity since 2005.

Methods:

A national Administrative and Resource Center is based in Alabama; regional and specialty nodes are based in Alabama, Florida, Illinois, Minnesota, Oregon, New York, and Texas. A Network Coordinating Center is based in Oregon. Studies are funded via investigator-initiated grants. Scientific productivity is assessed using specific metrics, including the Relative Citation Ratio.

Results:

To date, 58 studies have been completed or are in data collection or development. These studies have investigated a broad range of topics using a wide variety of study designs. Of the studies that have completed enrollment, 70,665 patients were enrolled, as were 19,827 practitioners (some participated in multiple studies), plus electronic records for 790,493 patients in two data-only studies. To date, these studies have led to 193 peer-reviewed scientific publications in 62 different journals. The mean (1.40) Relative Citation Ratio of Network publications connotes a greater-than-average influence in their fields.

Conclusions:

These metrics demonstrate that the PBRN research context can successfully engage practitioners and patients from diverse settings nationally with a high and sustained level of scientific productivity. This infrastructure has enabled clinical scientists in oral health and nonoral health topics and provided additional recruitment venues outside of the typical academic health center research context.

Dental practitioners' use of health risk assessments for a variety of health conditions: Results from the South Atlantic region of The National Dental Practice-Based Research Network

BACKGROUND

An important step in integrating dental and medical care is improving understanding of the frequency and characteristics of dental practitioners who conduct health risk assessments (HRAs).

METHODS

From September 2017 through July 2018, active dentist and hygienist members of the South Atlantic region of The National Dental Practice-Based Research Network (N = 870) were invited to participate in a survey evaluating their HRA practices (screening, measuring, discussing, referring patients) for 6 health conditions (obesity, hypertension, sexual activities, diabetes, alcohol use, tobacco use). For each health condition, the authors used ordinal logistic regression to measure the associations among the practitioner's HRA practices and the practitioner's characteristics, barriers, and practice characteristics.

RESULTS

Most of the 475 responding practitioners (≥ 72%) reported they at least occasionally complete 1 or more HRA steps for the health conditions except sexual activities. Most practitioners screened (that is, asked about) and gave referral information to affected patients for diabetes (56%) and hypertension (63%). Factors associated with each increased HRA practice for 2 or more outcomes were non-Hispanic white compared with Hispanic practitioner (cumulative odds ratio [COR] obesity, 0.4; 95% confidence interval [CI], 0.2 to 0.8; and COR diabetes, 0.3; 95% CI 0.2 to 0.8), male compared with female practitioner (COR tobacco, 0.3; 95% CI, 0.2 to 0.7; and COR hypertension, 0.4; 95% CI 0.2 to 0.8), and practitioner discomfort (COR, obesity and alcohol use, 0.7; 95% CI, 0.6 to 0.9; and COR, sexual activities 0.6; 95% CI 0.5 to 0.8).

CONCLUSIONS AND PRACTICAL IMPLICATIONS

Dental practitioners are conducting HRA practices for multiple conditions. Interventions should focus on reducing practitioner discomfort and target non-Hispanic white, male practitioners.

Practitioner Engagement in Activities of the National Dental Practice-Based Research Network (PBRN): 7-Year Results

PURPOSE

To 1) quantify practitioner activities of the National Dental Practice-Based Research Network (Network) for which Continuing Education (CE) credits were received (study training, videos, webinars, meetings, and symposia); 2) quantify practitioner coauthoring Network publications and presentations; and 3) test whether practitioner characteristics were associated with participation in these activities.

METHODS

A retrospective analysis of 4361 practitioners who enrolled in the Network between April 12, 2012 and October 12, 2018.

RESULTS

Overall, 59% (n = 2586) of practitioners earned CE credit from the Network; among these, 68% (n = 1757) from a video, 38% (n = 993) attended an annual Network meeting, 31% (n = 798) due to training for a Network clinical study, 9% (n = 226) attended a national symposium, and 7% (n = 170) participated in a Network webinar. Members of 2 large group practices earned on average more CEs than practitioners from other practice settings. Four percent (n = 159) of practitioners coauthored a Network presentation or publication. Practitioners who received their dental degree before 2000, were general practitioners, or were members of 2 large group practices, were more likely to have coauthored a publication or presentation.

CONCLUSION

This Network used a broad range of activities to engage community practitioners. These activities were successful in sustaining a high level of practitioner engagement in clinical research and its relevance to everyday clinical practice.

Practice based research in dentistry: an alternative to deal with clinical questions

Clinical interventions in dental practice should be determined based on the best scientific evidence available. Well-designed randomized clinical trials (RCTs) provide important evidence supporting the efficacy of interventions and are usually considered as the best primary evidence. However, the strict criteria adopted by most RCTs reduce their external validity since some findings from these studies might not work under usual conditions. On the other hand, practice-based research (PBR) studies have been designed to better define the effectiveness of clinical interventions under settings closer to "real-world" conditions. Therefore, this review aimed to describe different PBR designs discussing some advantages and limitations of such studies. The stimulus to organization PBR networks is discussed since the studies performed by these networks involve large number of clinicians and important conclusions can be drawn. Designs of observational studies including surveys and cohort studies based on practice are presented. Survey methods are important to know the behavior of practitioners regarding diagnostic and decision of treatment. Cohorts allow assessing different cofounders contributing to some outcome since large sample sizes and long follow-up periods can be observed in some of these studies. Pragmatic trials designed to take place in real-world clinical practice settings are also discussed as a useful design to assess the effectiveness of clinical interventions. In conclusion, this review sought to present PBR studies as alternative designs to answer clinical questions, but not replacing randomized clinical trials.

Parent Perceptions of and Preferences for Participation in Child Health Research: Results from a Pediatric Practice-Based Research Network

BACKGROUND

Recruitment efforts for child health research are often based on assumptions, therefore improving knowledge about parents' perceptions and preferences could enhance engagement.

AIM/OBJECTIVE

1) To describe parents' perceptions about and preferences for participation in child health research within a pediatric practice-based research network (PBRN), and 2) to investigate any associations with the presence of on-site PBRN research staff, office location, and child age.

METHODS

We conducted a 2-phase study with a convenience sample of parents from diverse office settings. Phase 1 was a qualitative assessment using semistructured, in-person interviews. Phase 2 consisted of a quantitative self-administered survey assessing: 1) perceptions of importance, benefits/motivations, and risks/barriers of child health research, and 2) preferences for recruitment method and enrollment location.

RESULTS

Parents (n = 627) uniformly perceived child health research to be important in prevention (89%), diagnosis (89%), and treatment (92%). They were motivated to participate most commonly by altruism and rarely by compensation. Parents perceived side effects (60%), discomfort (52%), and time (45%) as the main risks of participation. Most parents preferred to learn about research opportunities at their pediatric office (70%), and if interested, to enroll their child in their pediatric office (57%) or in their home (52%). Parents were significantly more altruistic and interested in participation in offices with on-site PBRN research staff and greater proximity to the University.

CONCLUSIONS

Child health researchers could enhance participation by using recruitment resources and enrollment strategies that match parent preferences, including engagement by on-site PBRN staff.

Leadership in practice-based research: The National Dental PBRN

Practice-based research networks with strong leadership can be effective venues for the translation of research findings. Coordinating all the efforts across a Network composed of individuals with a broad range of expertise, goals, and expectations can, however, be cumbersome, posing many different leadership challenges.
