Comparative Analysis of Sensory Responses from Dental Implants vs Natural Teeth: An In Vivo Study.

Purpose: To compare subjects' sensory responses to horizontal and vertical forces on tooth- and implant-supported restorations. Materials and Methods: In this prospective study, three protocols simulating the horizontal or vertical forces that occur during mastication were used to obtain subjective responses from subjects. These protocols included the measurement of horizontal force intensity during excursive movements and the identification of initial contact during guided and free vertical closure. Responses were recorded using a 1- to 10-point visual analog scale (VAS) and/ or monitored with electromyography (EMG) and Tekscan. Results: The study included 30 patients with a single implant-supported restoration (ISR) with a contralateral tooth-supported restoration (TSR). For horizontal forces similar to those of mastication (0.6 N), subject VAS scores were similar for both ISRs and TSRs at 6.3 vs 6.1, respectively. At reduced forces (0.2 and 0.4 N), subject responses were greater for the TSR at 3.4 and 5.4, respectively, as opposed to 1.2 and 2.6 for ISR, respectively (P < .01). During vertical guided closure (Test 1) at 25% of maximum bite force (MBF), subjects were more successful at correctly identifying initial contact of TSRs at a rate of 12 out of 17, compared to ISRs, which achieved a rate of 4 out of 13 (P < .1). In vertical free closure (Test 2), subject responses for the correct identification of initial contact at 50% MBF were similar for both TSRs and ISRs at 13 out of 17 and 9 out of 13, respectively. However, comparing the correct responses for subjects whose initial contacts were ISR showed a significant improvement in correct answers from Test 1 to Test 2, from 4 out of 13 correct to 9 out of 13 correct (P < .05). Conclusion: While the mechanism is not clear, subjects' ability to discern the horizontal and vertical forces at levels comparable to mastication appear similar between TSRs and ISRs.

Strains in the implant collars supporting a cantilevered cross-arch bar prosthesis. An in vitro study.

PURPOSE: To examine the strains in the collar area of implants supporting a cantilevered cross-arch bar prosthesis during vertical load application. MATERIALS AND METHODS: A milled cross-arch metal framework supported by four implants in a trapezoidal design was supported in polymethylmethacrylate. T-strain gage rosettes were attached to the crestal areas of the implants with two grids, one recording circumference strain of the crestal area of the implant and the second recording vertical strain, torquing strains of the implant. The framework was subject to vertical loading from an MTS 810 mechanical system. Loading sites were directly on anterior and posterior implants, and on a cantilever at 7.5, 15, 22.5, and 30 mm (0.5, 1.0, 1.5, and 2.0 of the anterior-posterior spread) distal from the posterior implant on the right side. The anterior-posterior (A-P) spread from anterior to posterior implants was 15 mm. Sites were loaded individually with 50 and 100 N. The data from the rosettes were transferred to a desktop computer and processed using StrainSmart 5000 software. RESULTS: Means and standard deviations were calculated for the 10 trials at each of the loading sites. Two-way ANOVAs were done separately for each dependent variable, the vertical grid, and the circumferential grid. The independent variables were the load magnitude and the load site. Tukey's test was used to compare groups post hoc. When directly loading the implants, loading the anterior implant resulted initially in compression followed by increasing tensile strain with 100 N loads. Loading the implant adjacent to cantilever (the posterior implant) resulted in greater strain at the collar than that observed with anterior implant with minimal bending strains. When loading the cantilever, anterior implant showed increasing bending strain at greater cantilever length, whereas the circumferential strains were greater for the supporting implant adjacent to the cantilever, particularly at 100 N loads, p ≤ 0.001. CONCLUSIONS: Limiting cantilever lengths to A-P spread ratios of 0.5 are preferred. Ratios greater than 1.0 should be avoided as flexing of the collar may occur. The dimensions of the implant, particularly wall thickness, adjacent to the cantilever should be carefully considered when planning the cantilevered implant-supported prosthesis.

Directly Observed Care: Crossing the Chasm of Quality Measurement.

After more than two decades of national attention to quality improvement in US healthcare, significant gaps in quality remain. A fundamental problem is that current approaches to measure quality are indirect and therefore imprecise, focusing on clinical documentation of care rather than the actual delivery of care. The National Academy of Medicine (NAM) has identified six domains of quality that are essential to address to improve quality: patient-centeredness, equity, timeliness, efficiency, effectiveness, and safety. In this perspective, we describe how directly observed care-a recorded audit of clinical care delivery-may address problems with current quality measurement, providing a more holistic assessment of healthcare delivery. We further show how directly observed care has the potential to improve each NAM domain of quality.

Effect of Electronic Health Record Clinical Decision Support on Contextualization of Care: A Randomized Clinical Trial.

Importance: Contextualizing care is a process of incorporating information about the life circumstances and behavior of individual patients, termed contextual factors, into their plan of care. In 4 steps, clinicians recognize clues (termed contextual red flags), clinicians ask about them (probe for context), patients disclose contextual factors, and clinicians adapt care accordingly. The process is associated with a desired outcome resolution of the presenting contextual red flag. Objective: To determine whether contextualized clinical decision support (CDS) tools in the electronic health record (EHR) improve clinician contextual probing, attention to contextual factors in care planning, and the presentation of contextual red flags. Design, Setting, and Participants: This randomized clinical trial was performed at the primary care clinics of 2 academic medical centers with different EHR systems. Participants were adults 18 years or older consenting to audio record their visits and their physicians between September 6, 2018, and March 4, 2021. Patients were randomized to an intervention or a control group. Analyses were performed on an intention-to-treat basis. Interventions: Patients completed a previsit questionnaire that elicited contextual red flags and factors and appeared in the clinician's note template in a contextual care box. The EHR also culled red flags from the medical record, included them in the contextual care box, used passive and interruptive alerts, and proposed relevant orders. Main Outcomes and Measures: Proportion of contextual red flags noted at the index visit that resolved 6 months later (primary outcome), proportion of red flags probed (secondary outcome), and proportion of contextual factors addressed in the care plan by clinicians (secondary outcome), adjusted for study site and for multiple red flags and factors within a visit. Results: Four hundred fifty-two patients (291 women [65.1%]; mean [SD] age, 55.6 [15.1] years) completed encounters with 39 clinicians (23 women [59.0%]). Contextual red flags were not more likely to resolve in the intervention vs control group (adjusted odds ratio [aOR], 0.96 [95% CI, 0.57-1.63]). However, the intervention increased both contextual probing (aOR, 2.12 [95% CI, 1.14-3.93]) and contextualization of the care plan (aOR, 2.67 [95% CI, 1.32-5.41]), controlling for whether a factor was identified by probing or otherwise. Across study groups, contextualized care plans were more likely than noncontextualized plans to result in improvement in the presenting red flag (aOR, 2.13 [95% CI, 1.38-3.28]). Conclusions and Relevance: This randomized clinical trial found that contextualized CDS did not improve patients' outcomes but did increase contextualization of their care, suggesting that use of this technology could ultimately help improve outcomes.

Patient-centered quality measurement for opioid use disorder: Development of a taxonomy to address gaps in research and practice.

Background: Evidence-based treatment is provided infrequently and inconsistently to patients with opioid use disorder (OUD). Treatment guidelines call for high-quality, patient-centered care that meets individual preferences and needs, but it is unclear whether current quality measures address individualized aspects of care and whether measures of patient-centered OUD care are supported by evidence. Methods: We conducted an environmental scan of OUD care quality to (1) evaluate patient-centeredness in current OUD quality measures endorsed by national agencies and in national OUD treatment guidelines; and (2) review literature evidence for patient-centered care in OUD diagnosis and management, including gaps in current guidelines, performance data, and quality measures. We then synthesized these findings to develop a new quality measurement taxonomy that incorporates patient-centered aspects of care and identifies priority areas for future research and quality measure development. Results: Across 31 endorsed OUD quality measures, only two measures of patient experience incorporated patient preferences and needs, while national guidelines emphasized providing patient-centered care. Among 689 articles reviewed, evidence varied for practices of patient-centered care. Many practices were supported by guidelines and substantial evidence, while others lacked evidence despite guideline support. Our synthesis of findings resulted in EQuIITable Care, a taxonomy comprised of six classifications: (1) patient Experience and engagement, (2) Quality of life; (3) Identification of patient risks; (4) Interventions to mitigate patient risks; (5) Treatment; and (6) Care coordination and navigation. Conclusions: Current quality measurement for OUD lacks patient-centeredness. EQuIITable Care for OUD provides a roadmap to develop measures of patient-centered care for OUD.

Cross-Sectional Associations: Social Risks and Diabetes Care Quality, Outcomes.

INTRODUCTION: Social risks (e.g., food/transportation insecurity) can hamper type 2 diabetes mellitus (T2DM) self-management, leading to poor outcomes. To determine the extent to which high-quality care can overcome social risks' health impacts, this study assessed the associations between reported social risks, receipt of guideline-based T2DM care, and T2DM outcomes when care is up to date among community health center patients. METHODS: A cross-sectional study of adults aged ≥18 years (N=73,484) seen at 186 community health centers, with T2DM and ≥1 year of observation between July 2016 and February 2020. Measures of T2DM care included up-to-date HbA1c, microalbuminuria, low-density lipoprotein screening, and foot examination, and active statin prescription when indicated. Measures of T2DM outcomes among patients with up-to-date care included blood pressure, HbA1c, and low-density lipoprotein control on or within 6‒12 months of an index encounter. Analyses were conducted in 2021. RESULTS: Individuals reporting transportation or housing insecurity were less likely to have up-to-date low-density lipoprotein screening; no other associations were seen between social risks and clinical care quality. Among individuals with up-to-date care, food insecurity was associated with lower adjusted rates of controlled HbA1c (79% vs 75%, p<0.001), and transportation insecurity was associated with lower rates of controlled HbA1c (79% vs 74%, p=0.005), blood pressure (74% vs 72%, p=0.025), and low-density lipoprotein (61% vs 57%, p=0.009) than among those with no reported need. CONCLUSIONS: Community health center patients received similar care regardless of the presence of social risks. However, even among those up to date on care, social risks were associated with worse T2DM control. Future research should identify strategies for improving HbA1c control for individuals with social risks. TRIAL REGISTRATION: This study is registered at www. CLINICALTRIALS: gov NCT03607617.

Treatment access for opioid use disorder in pregnancy among rural and American Indian communities.

BACKGROUND: Opioid use disorder (OUD) in pregnancy disproportionately impacts rural and American Indian (AI) communities. With limited data available about access to care for these populations, this study's objective was to assess clinic knowledge and new patient access for OUD treatment in three rural U.S. counties. MATERIAL AND METHODS: The research team used unannounced standardized patients (USPs) to request new patient appointments by phone for white and AI pregnant individuals with OUD at primary care and OB/GYN clinics that provide prenatal care in three rural Utah counties. We assessed a) clinic familiarity with buprenorphine for OUD; b) appointment availability for buprenorphine treatment; c) appointment wait times; d) referral provision when care was unavailable; and e) availability of OUD care at referral locations. We compared outcomes for AI and white USP profiles using descriptive statistics. RESULTS: The USPs made 34 calls to 17 clinics, including 4 with publicly listed buprenorphine prescribers on the Substance Abuse and Mental Health Services Administration website. Among clinical staff answering calls, 16 (47%) were unfamiliar with buprenorphine. OUD treatment was offered when requested in 6 calls (17.6%), with a median appointment wait time of 2.5 days (IQR 1-5). Among clinics with a listed buprenorphine prescriber, 2 of 4 (50%) offered OUD treatment. Most clinics (n = 24/28, 85.7%) not offering OUD treatment provided a referral; however, a buprenorphine provider was unavailable/unreachable 67% of the time. The study observed no differences in appointment availability between AI and white individuals. CONCLUSIONS: Rural-dwelling AI and white pregnant individuals with OUD experience significant barriers to accessing care. Improving OUD knowledge and referral practices among rural clinics may increase access to care for this high-risk population.

Impact of an unannounced standardized veteran program on access to community-based services for veterans experiencing homelessness.

BACKGROUND: The United States Department of Veterans Affairs established a program in which actors incognito portray veterans experiencing homelessness with pre-determined needs to identify barriers to access and services at community-based organizations. METHODS: From 2017 to 2019, actors who varied in gender, skin color and age portrayed one of three scripts at all VA Community-Based Resource and Referral Centers (CRRCs) serving veterans experiencing homelessness in 30 cities and completed an evaluative survey. They carried authentic VA identification and were registered in a VA patient database for each identity. CRRCs were provided with reports annually and asked to implement corrective plans. Data from the survey were analysed for change over time. RESULTS: Access to food, counselling, PTSD treatment, and hypertension/prediabetes care services increased significantly from 68-77% in year 2 to 83-97% in year 3 (each P < 0.05 adjusted for script present). A significant disparity in access for African American actors resolved following more uniform adherence to pre-existing policies. CONCLUSIONS: The 'unannounced standardized veteran' (USV) can identify previously unrecognized barriers to needed services and care. Audit and feedback programs based on direct covert observation with systematic data collection and rapid feedback may be an effective strategy for improving services to highly vulnerable populations.

Contextualizing care: An essential and measurable clinical competency.

Contextualizing care is the process of adapting research evidence to patient life context. The failure to do so, when it results in a care plan that is not likely to achieve its intended aim, is a contextual error. There is substantial evidence that contextual errors are common, adversely affect patient outcomes and health care costs, and are preventable. This evidence comes from over 5000 mostly incognito recordings of physician-patient encounters over a range of practice settings that have been analyzed along with the medical records of each encounter utilizing a specialized coding algorithm. Educational and practice improvement interventions have been tested at the medical student, resident, and attending level, each with evidence of benefits and limitations. The author argues that contextualizing care is an essential clinician competency and proposes an evidence-informed strategy for building and reinforcing the requisite skills across the continuum of medical education and professional development.

Implementation of a patient-collected audio recording audit & feedback quality improvement program to prevent contextual error: stakeholder perspective.

BACKGROUND: Using patient audio recordings of medical visits to provide clinicians with feedback on their attention to patient life context in care planning can improve health care delivery and outcomes, and reduce costs. However, such an initiative can raise concerns across stakeholders about surveillance, intrusiveness and merit. This study examined the perspectives of patients, physicians and other clinical staff, and facility leaders over 3 years at six sites during the implementation of a patient-collected audio quality improvement program designed to improve patient-centered care in a non-threatening manner and with minimal effort required of patients and clinicians. METHODS: Patients were invited during the first and third year to complete exit surveys when they returned their audio recorders following visits, and clinicians to complete surveys annually. Clinicians were invited to participate in focus groups in the first and third years. Facility leaders were interviewed individually during the last 6 months of the study. RESULTS: There were a total of 12 focus groups with 89 participants, and 30 leadership interviews. Two hundred fourteen clinicians and 800 patients completed surveys. In a qualitative analysis of focus group data employing NVivo, clinicians initially expressed concerns that the program could be disruptive and/or burdensome, but these diminished with program exposure and were substantially replaced by an appreciation for the value of low stakes constructive feedback. They were also significantly more confident in the value of the intervention in the final year (p = .008), more likely to agree that leadership supports continuous improvement of patient care and gives feedback on outcomes (p = .02), and at a time that is convenient (p = .04). Patients who volunteered sometimes expressed concerns they were "spying" on their doctors, but most saw it as an opportunity to improve care. Leaders were supportive of the program but not yet prepared to commit to funding it exclusively with facility resources. CONCLUSIONS: A patient-collected audio program can be implemented when it is perceived as safe, not disruptive or burdensome, and as contributing to better health care.

Development of an unannounced standardized patient protocol to evaluate opioid use disorder treatment in pregnancy for American Indian and rural communities.

BACKGROUND: Opioid use disorder (OUD) disproportionately impacts rural and American Indian communities and has quadrupled among pregnant individuals nationwide in the past two decades. Yet, limited data are available about access and quality of care available to pregnant individuals in rural areas, particularly among American Indians (AIs). Unannounced standardized patients (USPs), or "secret shoppers" with standardized characteristics, have been used to assess healthcare access and quality when outcomes cannot be measured by conventional methods or when differences may exist between actual versus reported care. While the USP approach has shown benefit in evaluating primary care and select specialties, its use to date for OUD and pregnancy is very limited. METHODS: We used literature review, current practice guidelines for perinatal OUD management, and stakeholder engagement to design a novel USP protocol to assess healthcare access and quality for OUD in pregnancy. We developed two USP profiles-one white and one AI-to reflect our target study area consisting of three rural, predominantly white and AI US counties. We partnered with a local community health center network providing care to a large AI population to define six priority outcomes for evaluation: (1) OUD treatment knowledge among clinical staff answering telephones; (2) primary care clinic facilitation and provision of prenatal care and buprenorphine treatment; (3) appropriate completion of evidence-based screening, symptom assessment, and initial steps in management; (4) appropriate completion of risk factor screening/probing about individual circumstances that may affect care; (5) patient-directed tone, stigma, and professionalism by clinic staff; and (6) disparities in care between whites and American Indians. DISCUSSION: The development of this USP protocol tailored to a specific environment and high-risk patient population establishes an innovative approach to evaluate healthcare access and quality for pregnant individuals with OUD. It is intended to serve as a roadmap for our own study and for future related work within the context of substance use disorders and pregnancy.

Advancing Health Equity by Avoiding Judgmentalism and Contextualizing Care.

This article examines the care of a Spanish-speaking woman with end-stage renal disease who returns repeatedly to the emergency department with complications related to missing hemodialysis. Her life circumstances suggest that she has been making difficult but rational decisions in an untenable situation, which is then readily resolved with the assistance of her care team. The case illustrates the pernicious effect of judgmentalism on patients from poor and marginalized communities, which exacerbates health inequity and illuminates the ethical importance of contextualizing patients' care.

Impact of Unannounced Standardized Patient Audit and Feedback on Care, Documentation, and Costs: an Experiment and Claims Analysis.

BACKGROUND: Meaningful variations in physician performance are not always discernible from the medical record. OBJECTIVE: We used unannounced standardized patients to measure and provide feedback on care quality and fidelity of documentation, and examined downstream effects on reimbursement claims. DESIGN: Static group pre-post comparison study conducted between 2017 and 2019. SETTING: Fourteen New Jersey primary care practice groups (22 practices) enrolled in Horizon BCBS's value-based program received the intervention. For claims analyses, we identified 14 additional comparison practice groups matched on county, practice size, and claims activity. PARTICIPANTS: Fifty-nine of 64 providers volunteered to participate. INTERVENTION: Unannounced standardized patients (USPs) made 217 visits portraying patients with 1-2 focal conditions (diabetes, depression, back pain, smoking, or preventive cancer screening). After two baseline visits to a provider, we delivered feedback and conducted two follow-up visits. MEASUREMENTS: USP-completed checklists of guideline-based provider care behaviors, visit audio recordings, and provider notes were used to measure behaviors performed and documentation errors pre- and post-feedback. We also compared changes in 3-month office-based claims by actual patients between the intervention and comparison practice groups before and after feedback. RESULTS: Expected clinical behaviors increased from 46% to 56% (OR = 1.53, 95% CI 1.29-1.83, p < 0.0001), with significant improvements in smoking cessation, back pain, and depression screening. Providers were less likely to document unperformed tasks after (16%) than before feedback (18%; OR = 0.74, 95% CI 0.62 to 0.90, p = 0.002). Actual claim costs increased significantly less in the study than comparison group for diabetes and depression but significantly more for smoking cessation, cancer screening, and low back pain. LIMITATIONS: Self-selection of participating practices and lack of access to prescription claims. CONCLUSION: Direct observation of care identifies hidden deficits in practice and documentation, and with feedback can improve both, with concomitant effects on costs.

Evaluation of a Patient-Collected Audio Audit and Feedback Quality Improvement Program on Clinician Attention to Patient Life Context and Health Care Costs in the Veterans Affairs Health Care System.

Importance: Evidence-based care plans can fail when they do not consider relevant patient life circumstances, termed contextual factors, such as a loss of social support or financial hardship. Preventing these contextual errors can reduce obstacles to effective care. Objective: To evaluate the effectiveness of a quality improvement program in which clinicians receive ongoing feedback on their attention to patient contextual factors. Design, Setting, and Participants: In this quality improvement study, patients at 6 Department of Veterans Affairs outpatient facilities audio recorded their primary care visits from May 2017 to May 2019. Encounters were analyzed using the Content Coding for Contextualization of Care (4C) method. A feedback intervention based on the 4C coded analysis was introduced using a stepped wedge design. In the 4C coding schema, clues that patients are struggling with contextual factors are termed contextual red flags (eg, sudden loss of control of a chronic condition), and a positive outcome is prospectively defined for each encounter as a quantifiable improvement of the contextual red flag. Data analysis was performed from May to October 2019. Interventions: Clinicians received feedback at 2 intensity levels on their attention to patient contextual factors and on predefined patient outcomes at 4 to 6 months. Main Outcomes and Measures: Contextual error rates, patient outcomes, and hospitalization rates and costs were measured. Results: The patients (mean age, 62.0 years; 92% male) recorded 4496 encounters with 666 clinicians. At baseline, clinicians addressed 413 of 618 contextual factors in their care plans (67%). After either standard or enhanced feedback, they addressed 1707 of 2367 contextual factors (72%), a significant difference (odds ratio, 1.3; 95% CI, 1.1-1.6; P = .01). In a mixed-effects logistic regression model, contextualized care planning was associated with a greater likelihood of improved outcomes (adjusted odds ratio, 2.5; 95% CI, 1.5-4.1; P < .001). In a budget analysis, estimated savings from avoided hospitalizations were $25.2 million (95% CI, $23.9-$26.6 million), at a cost of $337 242 for the intervention. Conclusions and Relevance: These findings suggest that patient-collected audio recordings of the medical encounter with feedback may enhance clinician attention to contextual factors, improve outcomes, and reduce hospitalizations. In addition, the intervention is associated with substantial cost savings.

How accurate is the medical record? A comparison of the physician's note with a concealed audio recording in unannounced standardized patient encounters.

OBJECTIVES: Accurate documentation in the medical record is essential for quality care; extensive documentation is required for reimbursement. At times, these 2 imperatives conflict. We explored the concordance of information documented in the medical record with a gold standard measure. MATERIALS AND METHODS: We compared 105 encounter notes to audio recordings covertly collected by unannounced standardized patients from 36 physicians, to identify discrepancies and estimate the reimbursement implications of billing the visit based on the note vs the care actually delivered. RESULTS: There were 636 documentation errors, including 181 charted findings that did not take place, and 455 findings that were not charted. Ninety percent of notes contained at least 1 error. In 21 instances, the note justified a higher billing level than the gold standard audio recording, and in 4, it underrepresented the level of service (P = .005), resulting in 40 level 4 notes instead of the 23 justified based on the audio, a 74% inflated misrepresentation. DISCUSSION: While one cannot generalize about specific error rates based on a relatively small sample of physicians exclusively within the Department of Veterans Affairs Health System, the magnitude of the findings raise fundamental concerns about the integrity of the current medical record documentation process as an actual representation of care, with implications for determining both quality and resource utilization. CONCLUSION: The medical record should not be assumed to reflect care delivered. Furthermore, errors of commission-documentation of services not actually provided-may inflate estimates of resource utilization.

Direct observation of depression screening: identifying diagnostic error and improving accuracy through unannounced standardized patients.

Background Depression is substantially underdiagnosed in primary care, despite recommendations for screening at every visit. We report a secondary analysis focused on depression of a recently completed study using unannounced standardized patients (USPs) to measure and improve provider behaviors, documentation, and subsequent claims for real patients. Methods Unannounced standardized patients presented incognito in 217 visits to 59 primary care providers in 22 New Jersey practices. We collected USP checklists, visit audio recordings, and provider notes after visits; provided feedback to practices and providers based on the first two visits per provider; and compared care and documentation behaviors in the visits before and after feedback. We obtained real patient claims from the study practices and a matched comparison group and compared the likelihood of visits including International Classification of Diseases, 10th Revision (ICD-10) codes for depression before and after feedback between the study and comparison groups. Results Providers significantly improved in their rate of depression screening following feedback [adjusted odds ratio (AOR), 3.41; 95% confidence interval (CI), 1.52-7.65; p = 0.003]. Sometimes expected behaviors were documented when not performed. The proportion of claims by actual patients with depression-related ICD-10 codes increased significantly more from prefeedback to postfeedback in the study group than in matched control group (interaction AOR, 1.41; 95% CI, 1.32-1.50; p < 0.001). Conclusions Using USPs, we found significant performance issues in diagnosis of depression, as well as discrepancies in documentation that may reduce future diagnostic accuracy. Providing feedback based on a small number of USP encounters led to some improvements in clinical performance observed both directly and indirectly via claims.

Listening to the Patient: A Typology of Contextual Red Flags in Disease Management Encounters.

PURPOSE: Patients send clues, often unwittingly, when they are grappling with a life challenge that complicates their care. For instance, a patient may lose control of a previously well-managed chronic condition or start missing appointments. When explored, these clues help clinicians uncover the life circumstance impacting the individual's ability to manage their health and health care. Such clues are termed "contextual red flags." Effective care requires recognizing them, asking about them, and customizing the care plan where feasible. We sought to develop a typology of contextual red flags by analyzing audio recordings along with the medical records of encounters between patients and providers in outpatient clinics. METHODS: During the course of 3 studies on physician attention to patient context conducted over a 5-year span (2012-2016), 4 full-time coders listened to the audios and reviewed the medical records of 2963 clinician-patient encounters. A list of contextual red flags was accrued and categorized until saturation was achieved. RESULTS: A total of 70 contextual red flags were sorted into 9 categories, comprising a typology of contextual red flags: uncontrolled chronic conditions; appointment adherence; resource utilization; medication adherence; adherence to plan of care; significant weight loss/gain; patient knowledge of health or health care status; medical equipment/supplies adherence; other. CONCLUSIONS: A relatively small number of clues that patients are struggling to self-manage their care warrant clinicians' exploring opportunities to adapt care plans to individual life circumstances. These contextual red flags group into an even smaller set of logical categories, providing a framework to guide clinicians about when to elicit additional information from patients about life challenges they are facing.

Efficacy of Several Retightening Protocols for Maintaining Clamping Force in the Implant-Abutment Joint: An In Vitro Pilot Study.

PURPOSE: Stability of an implant-supported restoration is an ultimate measure of the success of the procedure. It has been recommended by some to retighten the abutment screw for maintenance of the crown on the implant. The purpose of this study was to evaluate the usefulness of two retightening protocols to maintain the clamping force. MATERIALS AND METHODS: Three groups of slip-fit implants (MIS 4.3 by 10.5) were compared. The first group was only tightened once (group C). In the second group (group R10M), the screw was retightened after 10 minutes. The third group (group R2W) was retightened after 2 weeks of simulated functional loading. After completion of individual protocols, all specimens were loaded for 100,000 cycles. After the loading, all specimens had the remaining torque audited. RESULTS: The mean torque loss for group C was 6.10 (± 5.13) Ncm. Group R10M was 2.03 (± 3.018) Ncm, and group R2W was 0.30 (± 0.483) Ncm. A one-way analysis of variance (ANOVA) recorded significant differences among the groups (P = .003). Multiple pairwise comparisons between groups by Tukey test recorded significant differences between group C vs group R10M (P = .035) and group C vs group R2W (P = .002). There was no significant difference in torque loss between groups R10M and R2W (P = .509). CONCLUSION: Within the parameters of this in vitro investigation, it was concluded that both retightening after 10 minutes (P = .035) and after 2 weeks (P = .002) was equally effective.

Interproximal invasion as the basis of a Dental Risk Classification: a pilot study.

An important mission statement for modern dentistry is to maintain patients' implants and teeth for a lifetime. As a corollary, a standardized dental caries risk classification should provide the basis for evidence-based specific therapies. This paper proposes that interproximal caries lesions, also termed "restorative invasion," which destroys natural anatomical tooth structure with periodontal and occlusal sequelae, is a key factor in the cascade of destruction of the dentition and periodontitis. Thus it can serve as the basis for caries risk assessment. The standardized Dental Risk Classification system proposed here can provide a basis for therapeutic modalities as well as for public health assessment and insurance reimbursement.

Alerting Doctors About Patient Life Challenges: A Randomized Control Trial of a Previsit Inventory of Contextual Factors.

Objective. Effective care attends to relevant patient life context. We tested whether a patient-completed inventory helps providers contextualize care and increases patients' perception of patient-centered care (PCC). Method. The inventory listed six red flags (e.g., emergency room visits) and if the patient checked any, prompted for related contextual factors (e.g., transportation difficulties). Patients were randomized to complete the inventory or watch health videos prior to their visit. Patients presented their inventory results to providers during audio-recorded encounters. Audios were coded for physician probing and incorporating context in care plans. Patients completed the Consultation and Relational Empathy (CARE) instrument after the encounter. Results. A total of 272 Veterans were randomized. Adjusting for covariates and clustering within providers, inventory patients rated visits as more patient-centered (44.5; standard error = 1.1) than controls (42.7, standard error = 1.1, P = 0.04, CARE range = 10-50). Providers were more likely to probe red flags (odds ratio = 1.54; confidence interval = 1.07-2.22; P = 0.02) when receiving the inventory, but not incorporating context into care planning. Conclusion. A previsit inventory of life context increased perceptions of PCC and providers' likelihood of exploring context but not contextualizing care. Information about patients' life challenges is not sufficient to assure that context informs provider decision making even when provided at the point of care by patients themselves.
