Dentists evaluate their patients: an empirical investigation of preferences

What influences the provision and reception of oral health education? A narrative review of the literature

OBJECTIVES

Most common diseases of the mouth are preventable through behavioural changes, oral hygiene routines and regular professional care. Research suggests dental professionals may prioritize clinical experience, personal values and preferences over evidence when delivering such interventions. Research also suggests variable rates of patient behaviour change following oral health education (OHE) interactions. This review explores the literature to answer the question: what factors influence the provision and reception of OHE messages and the wider OHE process?

METHODS

A structured search of literature was carried out with databases covering a range of academic disciplines (healthcare sciences, social sciences, education). Key words/terms were searched to elicit papers published since 1998. Citation mining (relevant citations within papers) and citation tracking (papers citing relevant papers) were also used. Recurring themes within the papers were identified and coded using NVivo12 and presented in a conceptual model.

RESULTS

The studies analysed tended to employ small-scale surveys, larger-scale surveys (some with low response rates), or interview studies of varying sizes. There was also a limited number of review papers. However, several key messages were identified regarding dental professionals' and patients' views on OHE and the factors that influence its provision. Factors that were identified related to the wider social and policy context (macro), community-level factors (meso), the individual practitioner and patient (micro), factors that influenced the nature of OHE interaction and any resulting behaviour change, and how the outcomes of the process influence future OHE interactions for both parties.

CONCLUSIONS

The literature highlighted how factors influence the OHE process before, during and after the educational interaction. The resultant conceptual model acknowledges the influence of wider 'upstream' factors alongside interpersonal and individual influences which should be taken into consideration when developing OHE interventions.

Communication, Trust and Dental Anxiety: A Person-Centred Approach for Dental Attendance Behaviours

Effective communication forges the dentist-patient treatment alliance and is thus essential for providing person-centred care. Social rank theory suggests that shame, trust, communication and anxiety are linked together, they are moderated by socio-economic position. The study is aimed to propose and test an explanatory model to predict dental attendance behaviours using person-centred and socio-economic position factors. A secondary data analysis was conducted on a cross-sectional representative survey of a two-stage cluster sample of adults including England, Wales and Northern Ireland. Data were drawn from structured interview. Path analysis of proposed model was calculated following measurement development and confirmation of reliable constructs. The findings show model fit was good. Dental anxiety was predicted negatively by patient’s trust and positively by reported dentist communication. Patient’s shame was positively associated with dental anxiety, whereas self-reported dental attendance was negatively associated with dental anxiety. Both patient’s trust and dentist’s communication effects were moderated by social class. Manual classes were most sensitive to the reported dentist’s communications. Some evidence for the proposed model was found. The relationships reflected in the model were illuminated further when social class was introduced as moderator and indicated dentists should attend to communication processes carefully across different categories of patients.

The impact of dental phobia on care planning: a vignette study

Introduction A high percentage of people with dental phobia have poor oral health. This may be the result of delayed treatment or differences in care planning by the oral health care team.Aim This study sought to determine the effect, if any, of dental phobia and complexity of dental care on the proposed care plan devised by clinicians for patients.Design An experimental analogue study with independent variables of the presence of phobia and complexity of treatment need. Dependent variables included frequency of care planning elements such as periodontal treatment, prevention, restorations, root canal treatment, extraction and provision of crowns, bridges and prostheses.Participants Seventy-nine UK-based dental practitioners.Analysis The association between the case status (phobic versus non-phobic, simple versus complex) and the outcome variables were assessed using a chi-square test for association. Logistic regression analyses were also used to determine the predictors of care planning elements.Results There were no differences in care planning for phobic and non-phobic patients. Complexity of treatment need had significant effects on advanced periodontal treatment, restorations anterior and posterior, root canal treatment, provision of crowns, and extractions.Conclusions Care planning is influenced by patients' dental needs and not their phobic status.

Patient-dentist relationship and dental anxiety among young Sudanese adult patients

OBJECTIVE

To evaluate the effects of the patient-dentist relationship on dental anxiety among young adult Sudanese patients.

MATERIALS AND METHODS

In this cross-sectional study, 864 patients attending outpatient dental clinics of the governmental dental hospitals in Khartoum, Sudan were recruited; 51.2% were males and 48.8% were females, with an age range of 18-24 years. The questionnaire used evaluated the socio-demographics, education levels, economic status, patient experience, and also included the Dental Anxiety Scale, Corah (J Dent Res 1969 48: 596).

RESULTS

High dental anxiety was reported by 22.2%, 29.5% reported moderate dental anxiety, and 48.3% reported low or no dental anxiety. There were statistically significant associations between dental anxiety and gender, time lapse since the previous dental visit (P < 0.004) and the reason for the previous visit (P < 0.001). In addition, the dental clinic environment (P < 0.002), the time waiting before seeing the dentist (P < 0.001) and the overhearing of pain expressed by other patients (P < 0.001) were also statistically significant. Negative comments by the treating dentist also had a statistically significant impact (P < 0.032). In contrast, a clear explanation of related dental care (P < 0.008), as well as the allowance of adequate time to discuss oral health (P < 0.006), had significantly positive effects.

CONCLUSION

The study showed that the patient-dentist relationship had a significant association with dental anxiety, and may be an important target for improving the delivery and standards of oral health in dentally anxious patients in this region.

Can conditional health policies be justified? A policy analysis of the new NHS dental contract reforms

Conditional policies, which emphasise personal responsibility, are becoming increasingly common in healthcare. Although used widely internationally, they are relatively new within the UK health system where there have been concerns about whether they can be justified. New NHS dental contracts include the introduction of a conditional component that restricts certain patients from accessing a full range of treatment until they have complied with preventative action. A policy analysis of published documents on the NHS dental contract reforms from 2009 to 2016 was conducted to consider how conditionality is justified and whether its execution is likely to cause distributional effects. Contractualist, paternalistic and mutualist arguments that reflect notions of responsibility and obligation are used as justification within policy. Underlying these arguments is an emphasis on preserving the finite resources of a strained NHS. We argue that the proposed conditional component may differentially affect disadvantaged patients, who do not necessarily have access to the resources needed to meet the behavioural requirements. As such, the conditional component of the NHS dental contract reform has the potential to exacerbate oral health inequalities. Conditional health policies may challenge core NHS principles and, as is the case with any conditional policy, should be carefully considered to ensure they do not exacerbate health inequities.

Addressing Methodological Challenges in Large Communication Data Sets: Collecting and Coding Longitudinal Interactions in Home Hospice Cancer Care

In this article, we present strategies for collecting and coding a large longitudinal communication data set collected across multiple sites, consisting of more than 2000 hours of digital audio recordings from approximately 300 families. We describe our methods within the context of implementing a large-scale study of communication during cancer home hospice nurse visits, but this procedure could be adapted to communication data sets across a wide variety of settings. This research is the first study designed to capture home hospice nurse-caregiver communication, a highly understudied location and type of communication event. We present a detailed example protocol encompassing data collection in the home environment, large-scale, multisite secure data management, the development of theoretically-based communication coding, and strategies for preventing coder drift and ensuring reliability of analyses. Although each of these challenges has the potential to undermine the utility of the data, reliability between coders is often the only issue consistently reported and addressed in the literature. Overall, our approach demonstrates rigor and provides a "how-to" example for managing large, digitally recorded data sets from collection through analysis. These strategies can inform other large-scale health communication research.

How do dentists and their teams incorporate evidence about preventive care? An empirical study

OBJECTIVES

To identify how dentists and their teams adopt evidence-based preventive care.

METHODS

A qualitative study using grounded theory methodology was conducted. We interviewed 23 participants working in eight dental practices about their experience and work processes, while adopting evidence-based preventive care. During the study, Charmaz's grounded theory methodology was employed to examine the social process of adopting preventive dental care in dental practices. Charmaz's iteration of the constant comparative method was used during the data analysis. This involved coding of interview transcripts, detailed memo-writing and drawing diagrams. The transcripts were analyzed as soon as possible after each round of interviews in each dental practice. Coding was conducted primarily by AS, supported by team meetings and discussions when researchers compared their interpretations.

RESULTS

Participants engaged in a slow process of adapting evidence-based protocols and guidelines to the existing logistics of the practices. This process was influenced by practical, philosophical, and historical aspects of dental care, and a range of barriers and facilitators. In particular, dentists spoke spontaneously about two deeply held 'rules' underpinning continued restorative treatment, which acted as barriers to provide preventive care: (i) dentists believed that some patients were too 'unreliable' to benefit from prevention; and (ii) dentists believed that patients thought that only tangible restorative treatment offered 'value for money'. During the adaptation process, some dentists and teams transitioned from their initial state - selling restorative care - through an intermediary stage - learning by doing and educating patients about the importance of preventive care - and finally to a stage where they were offering patients more than just restorative care. Resources were needed for the adaptation process to occur, including: the ability to maintain the financial viability of the practice, appropriate technology, time, and supportive dental team relationships.

CONCLUSIONS

The findings from this study show that with considerable effort, motivation and coordination, it is possible for dental practices to work against the dental 'mainstream' and implement prevention as their clinical norm. This study has shown that dental practice is not purely scientific, but it includes cultural, social, and economic resources that interfere with the provision of preventive care.

Experiences of dental care: what do patients value?

BACKGROUND

Dentistry in Australia combines business and health care service, that is, the majority of patients pay money for tangible dental procedures such as fluoride applications, dental radiographs, dental fillings, crowns, and dentures among others. There is evidence that patients question dentists' behaviours and attitudes during a dental visit when those highly technical procedures are performed. However, little is known about how patients' experience dental care as a whole. This paper illustrates the findings from a qualitative study recently undertaken in general dental practice in Australia. It focuses on patients' experiences of dental care, particularly on the relationship between patients and dentists during the provision of preventive care and advice in general dental practices.

METHODS

Seventeen patients were interviewed. Data analysis consisted of transcript coding, detailed memo writing, and data interpretation.

RESULTS

Patients described their experiences when visiting dental practices with and without a structured preventive approach in place, together with the historical, biological, financial, psychosocial and habitual dimensions of their experience. Potential barriers that could hinder preventive activities as well as facilitators for prevention were also described. The offer of preventive dental care and advice was an amazing revelation for this group of patients as they realized that dentists could practice dentistry without having to "drill and fill" their teeth. All patients, regardless of the practice they came from or their level of clinical risk of developing dental caries, valued having a caring dentist who respected them and listened to their concerns without "blaming" them for their oral health status. These patients complied with and supported the preventive care options because they were being "treated as a person not as a patient" by their dentists. Patients valued dentists who made them aware of existing preventive options, educated them about how to maintain a healthy mouth and teeth, and supported and reassured them frequently during visits.

CONCLUSIONS

Patients valued having a supportive and caring dentist and a dedicated dental team. The experience of having a dedicated, supportive and caring dentist helped patients to take control of their own oral health. These dentists and dental teams produced profound changes in not just the oral health care routines of patients, but in the way patients thought about their own oral health and the role of dental professionals.

What factors influence the provision of preventive care by general dental practitioners?

BACKGROUND

What factors influence a general dental practitioner to offer preventive care to patients? A potential answer to this question is presented based on the findings of a qualitative study recently undertaken in general dental practice in Australia.

METHOD

A model of how practices come to be oriented towards preventive or restorative care is described, condensing all of the findings of the study into a single framework. Eight practices were studied and highlighted the interaction between two factors: leadership in practice and prioritisation of cultural, social and economic resources.

RESULTS

In this model, dentists' leadership to reorient the prioritisation of resources towards preventive care was crucial. Ideally a whole practice changed to preventive philosophy, but change was also possible in a single dentist within a practice. Prioritisation of resources was also key and interacted with dentist leadership. Prioritisation could be seen in the reorganisation of space, routines and fee schedules. During this process, one key support factor for dentists was their external networks of trusted peers and respected practicing dentists. These peers were crucial for transferring preventive knowledge within small networks of dentists who trusted one another; their influence was reportedly more important than centrally produced guidelines or academic advice. In order to help dentists change their practices towards preventive care, the findings from our study suggest that it is important to intervene in these local networks by identifying local dental opinion leaders. During this study, the key conditions needed for practices to reorient to preventive care included the presence of a committed leader with a prevention-supportive peer network, and the reorientation of space, routines and fee schedules to support preventive practice.

What makes primary care effective for people in poverty living with multiple chronic conditions?: study protocol

BACKGROUND

The inverse care law persists: people living in poverty have the greatest needs and face considerable challenges in getting the care they need. Evidence reveals that GPs encounter difficulties in delivering care to poor patients, while many of those patients feel stigmatized by healthcare professionals. Patients living in poverty report negative healthcare experiences and unmet healthcare needs. Indeed, there is a growing recognition in primary care research of the importance of addressing the capabilities and social conditions of the poor when delivering care. Few studies have looked at the factors contributing to effective and "socially responsive" care for people living in poverty.

METHODS/DESIGN

Our study adopts a qualitative ethnographic approach in four healthcare organizations in deprived areas of metropolitan Montreal (Québec, Canada), using patient shadowing techniques and interviews. Data will be collected through fieldwork observations and informal interviews with patients before and after consultations. We will observe medical consultations, care organization activities, and waiting areas and reception of patients. We will conduct a total of 36 individual interviews with 12 GPs and 24 patients. The interviews will be audio-recorded and transcribed for purposes of analysis. The analysis consists of debriefing sessions, coding and interpretive analysis.

DISCUSSION

This study aims to investigate how positive healthcare interactions between physicians and patients can improve the management of chronic conditions. We hypothesize that factors related to care organization, to healthcare professionals' experience and to patients may enhance the quality of healthcare interactions, which may have positive impacts for preventing and managing chronic conditions. Our study will provide a unique set of data grounded in the perspectives of healthcare professionals and of patients living in poverty.

Physicians' social competence in the provision of care to persons living in poverty: research protocol

Background

The quality of the physician-patient therapeutic relationship is a key factor in the effectiveness of care. Unfortunately, physicians and people living in poverty inhabit very different social milieux, and this great social distance hinders the development of a therapeutic alliance. Social competence is a process based on knowledge, skills and attitudes that support effective interaction between the physician and patient despite the intervening social distance. It enables physicians to better understand their patients' living conditions and to adapt care to patients' needs and abilities.

Methods/Design

This qualitative research is based on a comprehensive design using in-depth semi-structured interviews with 25 general practitioners working with low-income patients in Montreal's metropolitan area (Québec, Canada). Physicians will be recruited based on two criteria: they provide care to low-income patients with at least one chronic illness, and are identified by their peers as having expertise in providing care to a poor population. For this recruitment, we will draw upon contacts we have made in another research study (Loignon et al., 2009) involving clinics located in poor neighbourhoods. That study will include in-clinic observations and interviews with physicians, both of which will help us identify physicians who have developed skills for treating low-income patients. We will also use the snowball sampling technique, asking participants to refer us to other physicians who meet our inclusion criteria. The semi-structured interviews, of 60 to 90 minutes each, will be recorded and transcribed. Our techniques for ensuring internal validity will include data analysis of transcribed interviews, indexation and reduction of data with software qualitative analysis, and development and validation of interpretations.

Discussion

This research project will allow us to identify the dimensions of the social competence process that helps physicians establish therapeutic relationships with low-income patients living with chronic illness. This study will also offer concrete recommendations for improving health interventions among low-income patients and for helping them to better manage their chronic illnesses. Ultimately, our aim is to strengthen the capacity of the health care system and of professionals to provide care that is adapted to the social conditions of people living in poverty.

Dentist preferences for patients: dimensions and associations with provider, practice, and service characteristics

Provider-patient relations may influence the nature of care provided. The aim of this study was to examine dentist preferences for patients, relate these to characteristics of dentists and practices, and to services provided. A random sample of Australian dentists completed mailed questionnaires (response = 60.3%). Four factor-based subscales and an overall scale (Selectivity) were derived from a 37-item battery. The 4 subscales comprised treatment adherence (behavior relevant to the treatment situation), personal adaptability (willingness to cooperate when expected to do so), social interactiveness (positive affect, communicativeness, and appreciativeness), and enabling characteristics (willing and able to pay, and good dental knowledge). Reliability was adequate (Cronbach's alpha = 0.71-0.90). Treatment adherence was associated with higher orthodontic rates, but a lower extraction rate; social interactiveness was associated with higher extraction and denture rates; personal adaptability was associated with higher orthodontic rates, but lower general/miscellaneous service rates; enabling characteristics was associated with higher endodontic and crown and bridge rates; selectivity was associated with higher rates of diagnostic, preventive, and total services per visit. The associations with service rates indicated that provider preferences were related to treatment behavior that could affect the mix of services, indicating that the nature of care provided may be influenced by the provider-patient relation.

Perception of dental illness among persons receiving public assistance in Montreal

OBJECTIVES

We examined rationales for behaviors related to dental care among persons receiving public assistance in Montreal, Quebec.

METHODS

Fifty-seven persons receiving public assistance participated in 8 focus groups conducted in 2002. Sessions were recorded on audiotape and transcribed; analyses included debriefing sessions and coding and interpreting transcribed data.

RESULTS

In the absence of dental pain and any visible cavity, persons receiving public assistance believed they were free of dental illness. However, they knew that dental pain signals a pathological process that progressively leads to tooth decay and, therefore, should be treated by a dentist. However, when in pain, despite recognizing that they needed professional treatment, they preferred to wait and suffer because of a fear of painful dental treatments and a reluctance to undertake certain procedures.

CONCLUSIONS

Persons receiving public assistance have perceptions about dental health and illness that prevent them from receiving early treatment for tooth decay, which may lead to disagreements with dentists when planning dental treatments.

Inégalités sociales dans le recours aux soins dentaires

BACKGROUND

Despite excellent general health indices, Quebec is in a difficult situation concerning oral health: tooth loss remains at a high level in adults and reveals important social inequalities. The objective of this research was to show that dental health inequalities reflect inequalities in the demand for dental care.

METHODS

For the Dental Health Survey of Quebec 1998-1999, 9930 parents of children aged 5 to 8 years were randomly selected across Quebec and received a questionnaire at their home on the demand for dental care. Among them, 8430 adults completed and sent back the questionnaire (responses rate: 85%). After excluding edentulous persons, the sample was reduced to 6585 parents aged 30 to 44 years.

RESULTS

The majority of respondents (76.4% of women and 72.8% of men) visit the dentist in a preventive manner rather than wait until dental problems occur. However, our study shows important disparities: the proportion of preventive attenders increases as income increases. A multiple logistic regression model suggests that there are financial as well as cultural barriers in dental care access.

CONCLUSION

The proportion of preventive attenders is high in Quebec and allows practitioners to adopt a preventive management of dental caries. Social disparities are high however, and are associated with financial as well as cultural barriers that need to be reduced.

Microwave disinfection of dentures for the treatment of oral candidiasis

Thirty-four institutionalized subjects (mean age, 81 years) with a positive test for C. albicans pseudohyphae were randomly assigned to test (microwave) and control (soak) groups. All subjects received the same course of topical antifungal medication (Nystatin 300,000 IU lozenges 3x daily for 14 days). Subjects in the microwave treatment group had their maxillary denture scrubbed and then microwaved for one minute at 850 Watts. This procedure was repeated three times. For subjects receiving the standard denture soak treatment, the nursing staff was instructed to disinfect the maxillary dentures in 0.2% chlorhexidine digluconate solution overnight for 14 days, changing the solution every two days. Infestation of the tissue surface of the maxillary denture with C. albicans progressively took place over the three-month period following treatment such that 8 (53%) of the microwaved dentures and 16 (84%) of the soaked dentures demonstrated pseudohyphae as determined by Gram stain. Infection of the soft tissues with the hyphal form of C. albicans also increased with time. After three months, one (8%) patient in the microwave group and 12 (63%) patients in the denture soak group demonstrated pseudohyphae on the cytological smears. Re-infestation of the denture surface and infection of the adjacent soft tissue were delayed dramatically in patients whose dentures were microwaved compared with those whose dentures were disinfected by being soaked in a chlorhexidine solution. However, microwave treatment is not recommended for all dentures and should be used with caution.

Effects of perceived patient attributes on dentist communication behavior

The current study was designed to assess the relationship between dentists' communication behavior and their perception of patient attributes such as likeability, manageability, and prognosis. Six AEGD residents were videotaped, and their verbal and nonverbal communication behavior was analyzed in the manner described. Each resident was administered a 20-item questionnaire to determine his/her perception of patient attributes. For overall dentist nonverbal behavior, perception of the patient and the amount of recognized interruptions that the dentist allowed were significantly correlated (r = 0.28, p < 0.05). When the three dentist perception subcategories--Likeability, Manageability, and Prognosis--were analyzed, verbal and nonverbal communication leads were significantly correlated with the dentists' perceptions of patient attributes in each. The hypothesis of a relationship between patient communication behavior and the dentists' perceptions of patient attributes was supported. The results suggest that dentists alter their communication behavior depending on their assessment of various patient qualities. Whether training in interviewing techniques and communication behavior would have an effect on this process is unknown and should be addressed.

A primer on outcomes in dentistry

Expectations for evidence of "value" on the part of dental care purchasers and growth in the evidence-based dentistry movement are beginning to demonstrate the narrow and incomplete nature of dentistry's knowledge of the outcomes of dental conditions and treatment. In this paper a classification scheme for dental outcomes is described that illustrates the broad range of outcomes information important to patients, health care providers, purchasers, and society. The uses for outcomes information are discussed and suggestions are offered for improving dentistry's knowledge of outcomes through the cooperative involvement of dental research, dental education, and dental practice.

Customer service in dental offices: analyses of service orientations and waiting time in telephone interactions with a potential new customer

Increasing competition among health care organizations has prompted greater concern for the quality of "customer service" in brief encounters with patients. This study examined service practices engaged by dental office staff interacting over the telephone with a potential new customer. The goals of the study were to determine whether the staff displayed customer-oriented and control-oriented service communication behaviors and to examine the relation between these service behaviors and waiting time required of customers. Structured observational data were collected in phone encounters with staff in 84 dental offices. Approximately 40% of the staff engaged in the customer-oriented behavior of inviting the customer to share questions or concerns, and 31% exhibited the control-oriented behavior of reciting promotional pitches on behalf of the dental office. Six other communication behaviors were observed with less frequency. Staff who made customers wait on the line longer were more likely to use promotional pitches. Analyses revealed no significant relation between waiting time and other service communication behaviors.

Dentist-patient communication: a review of relevant models

A review of the literature on dental treatment was conducted and models presented of the doctor/dentist-patient relationship. These models are listed and divided into two subgroups, empirical and normative models. The models are scrutinized with focus on the dentist-patient communicative relationship exclusively. Different doctor/dentist-patient relationships are described. External factors influencing these relationships are defined. An analysis of dentist-patient communication is made, and a new model of dentist-patient communication is suggested, which states that what is done and what is said during dentist-patient encounters will have an impact on outcome. Three different purposes of dentist-patient communication are presented. The process of attaining these is discussed. It is concluded that a theory of communication is lacking in the dental context, and the need to develop a reliable and valid interaction analysis system for the patient-dentist communication is confirmed.

Comparison of ideal and actual behavior of patients and dentists during dental treatment

The ideal behavior of dentists and patients has seldom been studied with the aim of determining whether it is similar to the actual behavior of the two groups. Thus, the purpose of this study was to compare whether the ideal behavior of dentists and patients differed from their actual behavior. Thirty-three volunteering dentists and 271 of their patients from the public and private sectors in different parts of Finland participated in the study. The dentists first filled out a questionnaire with 5-scale Likert-type statements about the ideal patient and questions concerning their own background variables. In connection with normal dental practice their dental nurses selected 10 patients, who before treatment filled out a questionnaire containing statements about the desired behavior of an ideal dentist and their own background variables. Immediately after the treatment, both dentists and patients filled out another questionnaire containing similar statements, which this time indicated whether the dentist/patient actually behaved according to the ideal. Differences between each individual and the independent ideal and actual scores were compared by cross-tabulation and percentage agreement. With regard to the ideal behavior that was directly related to the treatment procedure, the expectations of both dentists and patients were usually met. In general, the patients did not disrupt the procedures and the dentists were able to concentrate on the treatment. The discrepancies most often found between the ideal and the actual behavior concerned the level of communication. The patients often would like to have been talked to more and wanted to be encouraged. The dentists were not sure whether their patients were interested in or motivated about the treatment or whether they followed the home care instructions. In general, there evidently is a clear gap in communication between dentists and patients, which may lead to frustration on both sides. It is thus suggested that when dentists are trained, more emphasis be placed on communication skills.

Variation in dentists' clinical decisions

OBJECTIVES

The first comprehensive review of the recent literature regarding variation in dentists' clinical treatment decisions is presented.

METHODS

Variation among dentists in the clinical decisions they make as well as the methods used for assessing this variation are examined at three levels of aggregation of clinical decisions: the dental practice (or dentist), the patient, and the individual tooth.

RESULTS

The extent to which differences in dentists' clinical decisions have been examined is limited. Studies are particularly sparse at the level of the dental practice, where the aggregate of dentists' treatment decisions is reflected. Further, the methods and measures used to assess variation tend to be different across studies, making quantification of variation difficult. Nevertheless, the available information reflects substantial variation in measures such as rates of provision of specific procedures; cost and numbers of procedures recommended for specific patients; and diagnoses, intervention decisions, and treatment selections for individual teeth.

CONCLUSIONS

Even when differences in patients are controlled, variation in dentists' clinical decisions is ubiquitous. While its consequences remain undetermined, the variation in basic clinical decisions such as caries diagnosis signals the need to consider the extent to which the appropriateness of care is affected.

Dentists' attitudes toward frustrating patient visits: relationship to satisfaction and malpractice complaints

A 22-item questionnaire measuring physician frustration in communicating with patients was adapted to dentists, and its reliability and validity assessed, in a sample of 289 English dental surgeons in general practice in Greater Manchester. Subscales were derived assessing the concepts of unpleasant dentist feelings, lack of communication, patient non-compliance, patient control, and practice organization with Cronbach's alpha ranging from 0.59 to 0.77. Three of five subscale scores (unpleasant feelings, lack of communication, and practice organization) were significantly greater for dentists who had official malpractice complaints to insurers. Similarly, all five subscores were greater for dentists who reported larger numbers of unsatisfactory visits and expressed greater dissatisfaction with dental practice.
