Abstract
Background
Patient–provider cost conversations can minimize cost-related barriers to health, while improving treatment adherence and patient satisfaction. The authors sought to identify factors associated with the occurrence of cost conversations in dentistry.
Methods
This was a cross-sectional study using data from an online, self-administered survey of US adults who had seen a dentist within the past 24 months at the time of the survey. Multivariable hierarchical logistic regression analysis was used to identify patient and provider characteristics associated with the occurrence of cost conversations.
Results
Of the 370 respondents, approximately two-thirds (68%) reported having a cost conversation with their dental provider during their last dental visit. Cost conversations were more likely for patients aged 25 through 34 years (odds ratio [OR], 2.84; 95% CI, 1.54 to 5.24), 35 through 44 years (OR, 3.35; 95% CI, 1.50 to 7.51), and 55 through 64 years (OR, 3.39; 95% CI, 1.38 to 8.28) than patients aged 18 through 24 years. Cost conversations were less likely to occur during visits with dental hygienists than during visits with general or family dentists (OR, 0.25; 95% CI, 0.11 to 0.58). In addition, respondents from the South (OR, 1.90; 95% CI, 1.04 to 3.48) and those screened for financial hardship were more likely to report having cost conversations with their dental providers (OR, 6.70; 95% CI, 2.69 to 16.71).
Conclusions
Within the study sample, cost conversations were common and were facilitated via financial hardship screening.
Practical Implications
Modifying oral health care delivery processes to incorporate financial hardship screening may be an effective way to facilitate cost conversations and provision of patient-centered care.

One way to accomplish this is to prioritize cost conversations between patients and their health care providers as part of a shared decision-making process. Such conversations can allow health care providers to identify the sources and magnitude of financial stress for patients and, in partnership with patients, tailor the care plan in a manner that minimizes the cost concerns of patients.

Despite the importance of cost conversations and patients’ desire for such conversations, they occur rarely, due to provider-related barriers such as provider discomfort with having these conversations, fear of damaging patient–provider relationships, lack of time, and lack of role clarity.

Although few researchers have characterized patient-related barriers to cost conversations, there is evidence to suggest that factors such as fear and discomfort with discussing cost issues with medical providers may prevent patients from initiating cost discussions with their providers.

Within dentistry, little is known about the extent to which cost conversations occur, despite the considerable cost-related barriers to oral health care. Specifically, to the best of our knowledge, there has been no empirical examination of whether and how cost conversations are happening within the oral health care setting. We sought to examine the factors associated with the occurrence of cost conversations between patients and oral health care providers.

Our research team partnered with Qualtrics to recruit 500 participants to complete a self-administered online survey. Sample size determination is less straightforward for nonprobability samples, and there is no widely accepted guideline. A probability-based sample of 385 would provide sufficient power for a prevalence estimation precision rate of plus or minus 5% at a 95% confidence level. Using this as a reference point, a sample size of 500 was identified as adequate for balancing the power to detect medium differences with survey cost and providing some cushion for nonresponse.

Recruitment
Qualtrics relies on actively managed opt-in market panels for study recruitment, including niche panels for specialized recruitment campaigns. Potential participants are invited to participate via email and are incentivized via Qualtrics. Internet protocol address tracking and digital fingerprinting technology are leveraged to prevent duplication.
Data collection
- ▪
The race and ethnicity question (previously combined into 1 question) was split into 2 (that is, race and then ethnicity) to allow for ease of quota determination; Qualtrics requested this change.
- ▪
Additional questions were included about site of dental visits (public, private, free clinic) and overall satisfaction with the dental visit.
Data were collected using an online self-administered survey developed by researchers on the basis of a review of the cost conversations literature. The survey was developed specifically for our study and, as such, had not been validated previously. To minimize survey fatigue and obtain trustworthy answers, the survey was designed to be short (facilitated using skip patterns where applicable); average completion time was 6 minutes.
- ▪
“For our research, careful attention to the survey questions is critical” (participants had to select “I understand”; participants selecting “I do not understand” were excluded).
- ▪“People are very busy these days and many do not have time to follow what goes on in their communities or countries. We are testing whether people read questions. To show that you’ve read this much, answer both “extremely interested” and “very interested” (participants selecting options other than the 2 specified options were excluded, n = 11).14Characteristics of participants and satisficing tendency in online surveys using a sample provider. Psyarxiv.
To ensure data quality, Qualtrics’ internal processes facilitate checks for evidence of satisficing, including short completion times and straightlining in questions using matrix style. Such observations are excluded and do not count toward the contractual final sample determination. For our study, there was 1 such observation. However, this respondent also responded inaccurately to the attention checks and was already accounted for in the surveys that had been deleted for data quality issues, as described previously.
Informed Consent
Participants had to consent to participating in our study before beginning the survey and after being presented with information about our study’s purpose and expectations of participants. Voluntary participation was stressed. The institutional review board at Georgia Southern University reviewed and approved the study protocol and survey.
Measures
Responses to these 2 statements were combined into a single binary measure (yes, no) of cost conversation. Participants responding in the affirmative to either of these statements were deemed to have had a cost conversation during their last dental visit. Participants responding in the negative for both statements were deemed not to have had a cost conversation.
Assessed covariates included patient demographic and provider information. Demographic information included gender (female, male, nonbinary), age (18-24 years, 25-34 years, 35-44 years, 45-54 years, 55-64 years, ≥ 65 years), race or ethnicity (non-Hispanic White, non-Hispanic Black, non-Hispanic other, Hispanic), personal income (< $25,000, $25,000 through $49,999, $50,000 through $74,999, $75,000 through $99,000, ≥ $100,000), location of residence (county with population of < 50,000, county with population of ≥ 50,000), dental insurance coverage (yes, no), experience of financial hardship (yes, no), and when the dental visit occurred (within 6 months, 7-12 months ago, 13-24 months ago). Provider characteristics included the type of practice in which the visit occurred (public, private), type of provider seen (general dentist, specialist dentist, dental hygienist or other), and whether the patient was screened for financial hardship during the visit (yes, no).
Data analysis
Participants who reported obtaining care from a free clinic (n = 28) were excluded for the purposes of our study owing to its focus on cost. After the exclusion of observations with missing data on the study variables, the final analytical sample for our study was 370, slightly fewer than the anticipated 385. However, had this been a probability-based study, the sample size of 370 would provide sufficient power for a prevalence estimation precision rate of plus or minus 5.1% at a 95% confidence level, just a little over the 5% margin of error estimated for a sample of 385.
Variables were described using frequencies. Bivariable associations were assessed using χ2 tests. Multivariable logistic regression was used to identify the patient and provider characteristics independently associated with the occurrence of cost conversations. A hierarchical model building approach was adopted in which patient characteristics, provider characteristics, and financial hardship screening information were added in blocks sequentially (models 1-3, respectively). Statistical significance was assessed at the P < .05 level using 2-tailed tests. Robust SEs were obtained and clustered at the state level. All analyses were performed using STATA, Version 16 (StataCorp).

Patient Characteristics
Age was found to be statistically associated with cost conversations, even after adjusting for patient and provider characteristics and financial hardship screening. Findings from model 3 indicate that cost conversations with dental providers were more likely to occur for patients aged 25 through 34 years (odds ratio [OR], 2.84; 95% CI, 1.54 to 5.24; P = .001), 35 through 44 years (OR, 3.35; 95% CI , 1.50 to 7.51; P = .003), and 55 through 64 years (OR, 3.39; 95% CI, 1.38 to 8.28; P = .008) than for patients aged 18 through 24 years. Hispanics were approximately 2 times more likely to have cost conversations with their dental providers, after adjusting for patient and provider characteristics (OR, 2.01; 95% CI, 1.08 to 3.73; P = .027). However, this association was no longer statistically significant at the P < .05 level, after adjusting for screening for financial hardship in model 3 (OR, 1.93; 95% CI, 0.90 to 4.13; P = .092).

Discussion
Our aim was to identify the factors associated with the occurrence of patient–dental provider cost conversations. Approximately two-thirds of survey respondents reported having a cost conversation with a dentist or clinical staff member during their last dental visit. In multivariable regression analysis, factors found to be independently associated with cost conversations included patient’s age, experience of financial hardship, region of residence, type of dental provider seen, and financial hardship screening. Screening for financial hardship was found to be the most important factor associated with the occurrence of cost conversations in our study.

We propose 3 possible explanations for this finding. On the one hand, differences in reported estimates may be due to variations in how cost conversation is defined and measured. On the other hand, our use of a nonprobability sampling approach may have biased the estimates. Online opt-in panel samples have previously been reported to yield higher estimates on nondemographic questions than nationally representative benchmark samples; reported estimates of the differences ranged from 2% through 14%.

However, assuming the cost conversation rate estimated from our study is close to the true national estimate, it would suggest that cost conversations may be a relatively routine practice in dentistry. It is possible that dental providers are more cost-responsive compared with their medical counterparts due to the relatively higher price elasticity and out-of-pocket burden associated with oral health care.,

In our study, age, region of residence, Hispanic ethnicity, reported financial hardship, and specialist dental visits were all found to be positively associated with cost conversations. Hispanic ethnicity, age, and South region have previously been associated with higher unmet need for oral health care or a higher likelihood of reported cost-related barriers to oral health care use.

Positive associations between reported financial hardship and Hispanic ethnicity and cost conversations were no longer statistically significant after adjusting for financial hardship screening, suggestive of higher financial hardship screening rates among these populations. Similarly, financial hardship screening appeared to mediate the positive relationship between specialist dental visits and cost conversations, also suggesting higher financial hardship screening rates in such settings. Dental subspecialty services tend to be more expensive, perhaps explaining the higher financial hardship screening rates and incidence of cost conversations. This is corroborated by the finding of a lower occurrence of cost discussions during dental hygienist visits, when the preventative services provided tend to be more affordable.

making financial hardship screening routine can be a helpful approach for identifying patient financial stress and ensuring the delivery of cost-responsive, quality, patient-centered, oral health care to all patients.
Limitations
Our study was a cross-sectional study, and therefore we cannot assert causal associations between each of the assessed correlates of cost conversations and the occurrence of cost conversations. Furthermore, we recruited participants using a nonprobability sampling approach from an opt-in market panel, resulting in potential selection and voluntary response bias. The extent to which the findings may be generalized to the broader population, especially older adults, may be considerably limited.
There were also some limitations with the survey instrument used in our study, including lack of previous validation. Participants could have also responded to questions related to cost conversations with different frames of reference, leading to potential bias. In addition, the questions used in assessing cost conversations focused on discussions related solely to medical costs. Furthermore, the quality checks used in the survey were placed at the beginning rather than interspersed within the survey, which allowed us to immediately exclude those who did not have serious intentions about the survey from the start. However, given the brevity of the survey, we believe quality issues due to survey fatigue were of limited concern. Collectively, these survey-related factors could have potentially influenced the validity of the responses and our resulting estimates.
In addition, we may not have accounted for all potential correlates of cost conversations, including patients’ education or employment and providers’ attitudes and beliefs toward cost conversations. In addition, detailed information on the type of dental visit the patient had (for example, diagnostic visit, preventive or hygiene visits, treatment visits, or reviews) or the site of care (including whether care was received in a hospital-based or dental education institution–based dental facility) were not obtained.

The 24-month period allowed for adequate sampling and afforded the opportunity to account for the potential impact of the pandemic on oral health care experiences. We included a variable in the regression model measuring when the last dental visit took place. The lack of statistically significant association of this variable with cost conversations suggests that the pandemic and time-related recall bias may have had a minimal effect on estimates.
Despite these limitations, our study represents one of the only attempts to our knowledge to examine cost conversations within the dental setting. Because we took an empirical approach, our study results add to a cost conversation evidence base that has mostly been dominated by qualitative studies. In future studies, researchers can extend this exploratory study using nationally representative and probability-based sampling approaches to confirm the broad applicability of our study’s findings. Furthermore, additional studies are needed to develop valid measurement instruments for assessing the occurrence and quality of cost conversations.
Conclusions
Our aim was to fill a gap in the literature via examining the factors associated with patient–dental provider cost conversations. Taken together, the findings suggest that patient–dental provider cost conversations, partly facilitated by financial hardship screening, may be occurring for financially vulnerable populations and in high-cost oral health care settings. The findings also support the need for routine financial hardship screening in oral health care settings to identify and address patients’ cost concerns and to facilitate the delivery of quality, patient-centered, and cost-responsive oral health care.
