Validation of 2 New Measures of Continuity of Care Based on Year-to-Year Follow-up With Known Providers of Health Care

PURPOSE

In a primary care context favoring group practices, we assessed the validity of 2 new continuity measures (both versions of known provider continuity, KPC) that capture the concentration of care over time from multiple physicians (multiple provider continuity, KPC-MP) or from the physician seen most often (personal provider continuity, KPC-PP).

METHODS

Patients with diabetes or cardiovascular disease (N = 765) were approached in the waiting rooms of 28 primary care clinics in 3 regions of the province of Quebec, Canada; answered a survey questionnaire measuring relational continuity, interpersonal communication, coordination within the clinic, coordination with specialists, and overall coordination; and gave permission for their medical records to be reviewed and their medical services utilization data for the previous 2 years to be accessed to measure KPC. Using generalized linear mixed models, we assessed the association between KPC and the patients’ responses.

RESULTS

Among the 5 different patient-reported measures or their combination, KPC-MP was significantly related with overall coordination of care: for high continuity, the odds ratio (OR) = 2.02 (95% CI, 1.33–3.07), and for moderate continuity, OR = 1.61 (95% CI, 1.06–2.46). KPC-MP was also related with the combined continuity score: for high continuity, OR = 1.52 (95% CI, 1.11–2.09), and for moderate continuity, OR = 1.48 (95% CI, 1.10–2.00). KPC-PP was not significantly associated with any of the survey measures.

CONCLUSIONS

The KPC-MP measure, based on readily available administrative data, is associated with patient-perceived overall coordination of care among multiple physicians. KPC measures are potentially a valuable and low-cost way to follow the effects of changes favoring group practice on continuity of care for entire populations. They are easy to replicate over time and across jurisdictions.     

Effects of Patient-Centered Medical Home Attributes on Patients’ Perceptions of Quality in Federally Supported Health Centers

PURPOSE

We sought to assess patients’ ratings of patient-centered medical home (PCMH) attributes and overall quality of care within federally supported health centers.

METHODS

Data were collected through the 2009 Health Center Patient Survey (n = 4,562), which consisted of in-person interviews and included a nationally representative sample of patients seen in health centers. Quality measures included patients’ perceptions of overall quality of services, perceptions of quality of clinician advice/treatment, and likelihood of referring friends and relatives to the health center. PCMH attributes included (1) access to care getting to health center, (2) access to care during visit, (3) patient-centered communication with health care clinicians, (4) patient-centered communication with support staff, (5) self-management support for chronic conditions, (6) self-management support for behavioral risks, and (7) comprehensive preventive care. Bivariate analysis and logistic regressions were used to examine associations between patients’ perceptions of PCMH attributes and patient-reported quality of care.

RESULTS

Eighty-four percent of patients reported excellent/very good overall quality of services, 81% reported excellent/very good quality of clinician care, and 84% were very likely to refer friends and relatives. Higher patient ratings on the access to care and patient-centered communication attributes were associated with higher odds of patient-reported high quality of care on the 3 outcome measures.

CONCLUSIONS

More than 80% of patients perceived high quality of care in health centers. PCMH attributes related to access to care and communication were associated with greater likelihood of patients reporting high-quality care.     

Cancer patient and clinician acceptability and feasibility of a supportive care screening and referral process

Background

Incorporating supportive care into routine cancer care is an increasing priority for the multi‐disciplinary team with growing evidence of its importance to patient‐centred care. How to design and deliver a process which is appropriate for patients, clinicians and health services in rural areas needs further investigation.

Objective

To (i) examine the patient and clinician acceptability and feasibility of incorporating a supportive care screening and referral process into routine cancer care in a rural setting, and (ii) explore any potential influences of patient variables on the acceptability of the process.

Methods

A total of 154 cancer patients and 36 cancer clinicians across two rural areas of Victoria, Australia participated. During treatment visits, patients and clinicians participated in a supportive care process involving screening, discussion of problems, and provision of information and referrals. Structured questionnaires with open and closed questions were used to measure patient and clinician acceptability and feasibility.

Results

Patients and clinicians found the supportive care process highly acceptable. Screening identified relevant patient problems (90%) and problems that may not have otherwise been identified (83%). The patient–clinician discussion helped patients realize help was available (87%) and enhanced clinician–patient rapport (72%). Patients received useful referrals to services (76%). Feasibility issues included timing of screening for newly diagnosed patients, privacy in discussing problems, clinician time and availability of referral options. No patient demographic or disease factors influenced acceptability or feasibility.

Conclusions

Patients and clinicians reported high acceptability for the supportive care process, although mechanisms for incorporating the process into health care need to be further developed.     

Impact of Continuity of Care on Mortality and Health Care Costs: A Nationwide Cohort Study in Korea

PURPOSE

Continuity of care is considered a core element of high-quality primary care, but its impact on mortality and health care costs is unclear. We aimed to determine the impact of continuity of care on mortality, costs, and health outcomes in patients with newly diagnosed cardiovascular risk factors.

METHODS

We conducted a cohort study of a 3% nationwide random sample of Korean National Health Insurance enrollees. A total of 47,433 patients who had received new diagnoses of hypertension, diabetes, hypercholesterolemia, or their complications in 2003 or 2004 were included. We determined standard indices of continuity of care—most frequent provider continuity (MFPC), modified, modified continuity index (MMCI), and continuity of care index (COC)—and evaluated their association with study outcomes over 5 years of follow-up. Outcome measures included overall mortality, cardiovascular mortality, incident cardiovascular events, and health care costs.

RESULTS

The multivariable-adjusted hazard ratios (HRs) for all-cause mortality, cardiovascular mortality, incident myocardial infarction, and incident ischemic stroke comparing participants with COC index below the median to those above the median were HR = 1.12 (95% CI, 1.04–1.21), 1.30 (1.13–1.50), 1.57 (1.28–1.95), and 1.44 (1.27–1.63), respectively. Similar findings were obtained for other indices of continuity of care. Lower continuity of care was also associated with increased inpatient and outpatient days and costs.

CONCLUSIONS

Lower indices of continuity of care in patients with newly diagnosed hypertension, diabetes, and hypercholesterolemia were associated with higher all-cause and cardiovascular mortality, cardiovascular events, and health care costs. Health care systems should be designed to support long-term trusting relationships between patients and physicians.     

Influence of Shared Medical Appointments on Patient Satisfaction: A Retrospective 3-Year Study

PURPOSE

Shared medical appointments (SMAs) are becoming popular, but little is known about their association with patient experience in primary care. We performed an exploratory analysis examining overall satisfaction and patient-centered care experiences across key domains of the patient-centered medical home among patients attending SMAs vs usual care appointments.

METHODS

We undertook a cross-sectional study using a mailed questionnaire measuring levels of patient satisfaction and other indicators of patient-centered care among 921 SMA and 921 usual care patients between 2008 and 2010. Propensity scores adjusted for potential case mix differences between the groups. Multivariate logistic regression assessed propensity-matched patients’ ratings of care. Generalized estimating equations accounted for physician-level clustering.

RESULTS

A total of 40% of SMA patients and 31% of usual care patients responded. In adjusted analyses, SMA patients were more likely to rate their overall satisfaction with care as “very good” when compared with usual care counterparts (odds ratio = 1.26; 95% CI, 1.05–1.52). In the analysis of patient-centered medical home elements, SMA patients rated their care as more accessible and more sensitive to their needs, whereas usual care patients reported greater satisfaction with physician communication and time spent during their appointment.

CONCLUSIONS

Overall, SMA patients appear more satisfied with their care relative to patients receiving usual care. SMAs may also improve access to care and deliver care that patients find to be sensitive to their needs. Further research should focus on enhancing patient-clinician communication within an SMA as this model of care becomes more widely adopted.     

Annals Journal Club: Strategies for Reducing Potentially Avoidable Hospitalizations for Ambulatory Care–Sensitive Conditions

PURPOSE

Hospitalizations for ambulatory care–sensitive conditions (ACSCs) are seen as potentially avoidable with optimal primary care. Little is known, however, about how primary care physicians rate these hospitalizations and whether and how they could be avoided. This study explores the complex causality of such hospitalizations from the perspective of primary care physicians.

METHODS

We conducted semistructured interviews with 12 primary care physicians from 10 primary care clinics in Germany regarding 104 hospitalizations of 81 patients with ACSCs at high risk of rehospitalization.

RESULTS

Participating physicians rated 43 (41%) of the 104 hospitalizations to be potentially avoidable. During the interviews the cause of hospitalization fell into 5 principal categories: system related (eg, unavailability of ambulatory services), physician related (eg, suboptimal monitoring), medical (eg, medication side effects), patient related (eg, delayed help-seeking), and social (eg, lack of social support). Subcategories frequently associated with physicians’ rating of hospitalizations for ACSCs as potentially avoidable were after-hours absence of the treating physician, failure to use ambulatory services, suboptimal monitoring, patients’ fearfulness, cultural background and insufficient language skills of patients, medication errors, medication nonadherence, and overprotective caregivers. Comorbidities and medical emergencies were frequent causes attributed to ACSC-based hospitalizations that were rated as being unavoidable.

CONCLUSIONS

Primary care physicians rated a significant proportion of hospitalizations for ACSCs to be potentially avoidable. Strategies to avoid these hospitalizations may target after-hours care, optimal use of ambulatory services, intensified monitoring of high-risk patients, and initiatives to improve patients’ willingness and ability to seek timely help, as well as patients’ medication adherence.     

Relationship Between Clinical Quality and Patient Experience: Analysis of Data From the English Quality and Outcomes Framework and the National GP Patient Survey

PURPOSE

Clinical quality and patient experience are both widely used to evaluate the quality of health care, but the relationship between these 2 domains remains uncertain. The aim of this study was to examine this relationship using data from 2 established measures of quality in primary care in England.

METHODS

Practice-level analyses (N = 7,759 practices in England) were conducted on measures of patient experience from the national General Practice Patient Survey (GPPS), and measures of clinical quality from the national pay-for-performance scheme (Quality and Outcomes Framework). Spearman’s rank correlation and multiple linear regression were used on practice-level estimates.

RESULTS

Although all the correlations between clinical quality summary scores and patient survey scores are positive, and most are statistically significant, the strength of the associations was weak, with the highest correlation coefficient reaching 0.18, and more than one-half were 0.11 or less. Correlations with clinical quality were highest for patient-reported access scores (telephone access 0.16, availability of urgent appointments 0.15, ability to book ahead 0.18, ability to see preferred doctor 0.17) and overall satisfaction (0.15).

CONCLUSION

Although there are associations between clinical quality and measures of patient experience, the 2 domains of care quality remain predominantly distinct. The strongest correlations are observed between practice clinical quality and practice access, with very low correlations between clinical quality and interpersonal aspects of care. The quality of clinical care and the quality of interpersonal care should be considered separately to give an overall assessment of medical care.     

Clinicians’ Implicit Ethnic/Racial Bias and Perceptions of Care Among Black and Latino Patients

PURPOSE

We investigated whether clinicians’ explicit and implicit ethnic/racial bias is related to black and Latino patients’ perceptions of their care in established clinical relationships.

METHODS

We administered a telephone survey to 2,908 patients, stratified by ethnicity/race, and randomly selected from the patient panels of 134 clinicians who had previously completed tests of explicit and implicit ethnic/racial bias. Patients completed the Primary Care Assessment Survey, which addressed their clinicians’ interpersonal treatment, communication, trust, and contextual knowledge. We created a composite measure of patient-centered care from the 4 subscales.

RESULTS

Levels of explicit bias were low among clinicians and unrelated to patients’ perceptions. Levels of implicit bias varied among clinicians, and those with greater implicit bias were rated lower in patient-centered care by their black patients as compared with a reference group of white patients (P = .04). Latino patients gave the clinicians lower ratings than did other groups (P <.0001), and this did not depend on the clinicians’ implicit bias (P = .98).

CONCLUSIONS

This is among the first studies to investigate clinicians’ implicit bias and communication processes in ongoing clinical relationships. Our findings suggest that clinicians’ implicit bias may jeopardize their clinical relationships with black patients, which could have negative effects on other care processes. As such, this finding supports the Institute of Medicine’s suggestion that clinician bias may contribute to health disparities. Latinos’ overall greater concerns about their clinicians appear to be based on aspects of care other than clinician bias.Key words: race, ethnicity, communication, prejudice, patient-centered care, healthcare disparities, primary care, practice-based research     

Willingness to Exchange Health Information via Mobile Devices: Findings From a Population-Based Survey

PURPOSE

The rapid proliferation of mobile devices offers unprecedented opportunities for patients and health care professionals to exchange health information electronically, but little is known about patients’ willingness to exchange various types of health information using these devices. We examined willingness to exchange different types of health information via mobile devices, and assessed whether sociodemographic characteristics and trust in clinicians were associated with willingness in a nationally representative sample.

METHODS

We analyzed data for 3,165 patients captured in the 2013 Health Information National Trends Survey. Multinomial logistic regression analysis was conducted to test differences in willingness. Ordinal logistic regression analysis assessed correlates of willingness to exchange 9 types of information separately.

RESULTS

Participants were very willing to exchange appointment reminders (odds ratio [OR] = 6.66; 95% CI, 5.68–7.81), general health tips (OR = 2.03; 95% CI, 1.74–2.38), medication reminders (OR = 2.73; 95% CI, 2.35–3.19), laboratory/test results (OR = 1.76; 95% CI, 1.62–1.92), vital signs (OR = 1.63; 95% CI, 1.48–1.80), lifestyle behaviors (OR = 1.40; 95% CI, 1.24–1.58), and symptoms (OR = 1.62; 95% CI, 1.46–1.79) as compared with diagnostic information. Older adults had lower odds of being more willing to exchange any type of information. Education, income, and trust in health care professional information correlated with willingness to exchange certain types of information.

CONCLUSIONS

Respondents were less willing to exchange via mobile devices information that may be considered sensitive or complex. Age, socioeconomic factors, and trust in professional information were associated with willingness to engage in mobile health information exchange. Both information type and demographic group should be considered when developing and tailoring mobile technologies for patient-clinician communication.     

The Patient‐Centered Medical Home and Patient Experience

Objective

To examine the relationship between practices'' reported use of patient-centered medical home (PCMH) processes and patients'' perceptions of their care experience.

Data Source

Primary survey data from 393 physician practices and 1,304 patients receiving care in those practices.

Study Design

This is an observational, cross-sectional study. Using standard ordinary least-squares and a sample selection model, we estimated the association between patients'' care experience and the use of PCMH processes in the practices where they receive care.

Data Collection

We linked data from a nationally representative survey of individuals with chronic disease and two nationally representative surveys of physician practices.

Principal Findings

We found that practices'' use of PCMH processes was not associated with patient experience after controlling for sample selection as well as practice and patient characteristics.

Conclusions

In our study, which was large, but somewhat limited in its measures of the PCMH and of patient experience, we found no association between PCMH processes and patient experience. The continued accumulation of evidence related to the possibilities of the PCMH, how PCMH is measured, and how the impact of PCMH is gauged provides important information for health care decision makers.     

Engaging Primary Care Patients to Use a Patient-Centered Personal Health Record

PURPOSE

Health care leaders encourage clinicians to offer portals that enable patients to access personal health records, but implementation has been a challenge. Although large integrated health systems have promoted use through costly advertising campaigns, other implementation methods are needed for small to medium-sized practices where most patients receive their care.

METHODS

We conducted a mixed methods assessment of a proactive implementation strategy for a patient portal (an interactive preventive health record [IPHR]) offered by 8 primary care practices. The practices implemented a series of learning collaboratives with practice champions and redesigned workflow to integrate portal use into care. Practice implementation strategies, portal use, and factors influencing use were assessed prospectively.

RESULTS

A proactive and customized implementation strategy designed by practices resulted in 25.6% of patients using the IPHR, with the rate increasing 1.0% per month over 31 months. Fully 23.5% of IPHR users signed up within 1 day of their office visit. Older patients and patients with comorbidities were more likely to use the IPHR, but blacks and Hispanics were less likely. Older age diminished as a factor after adjusting for comorbidities. Implementation by practice varied considerably (from 22.1% to 27.9%, P <.001) based on clinician characteristics and workflow innovations adopted by practices to enhance uptake.

CONCLUSIONS

By directly engaging patients to use a portal and supporting practices to integrate use into care, primary care practices can match or potentially surpass the usage rates achieved by large health systems.     

The Importance of a High‐Performance Work Environment in Hospitals

Objective

To examine the benefits of a high-performance work environment (HPWE) for employees, patients, and hospitals.

Study Setting

Forty-five adult, medical-surgical units in nine hospitals in upstate New York.

Study Design

Cross-sectional study.

Data Collection

Surveys were collected from 1,527 unit-based hospital providers (68.5 percent response rate). Hospitals provided unit turnover and patient data (16,459 discharge records and 2,920 patient surveys).

Principal Findings

HPWE, as perceived by multiple occupational groups on a unit, is significantly associated with desirable work processes, retention indicators, and care quality.

Conclusion

Our findings underscore the potential benefits for providers, patients, and health care organizations of designing work environments that value and support a broad range of employees as having essential contributions to make to the care process and their organizations.     

Care From Family Physicians Reported by Pregnant Women in the United States

PURPOSE

We describe the proportion of family physicians providing care of any sort to pregnant women in the United States from 2000 to 2009.

METHODS

We used a repeat, cross-sectional design with data from the nationally representative Integrated Health Interview Series (2000–2009) for respondents who reported being pregnant at the time of the survey (N = 3,204). Using multivariate logistic regression, we modeled changes over time in pregnant women’s reports of care from family physicians. We used interaction terms to test for regional differences in trends.

RESULTS

Approximately one-third of pregnant women reported having seen or talked to a family physician for medical care during the prior year, a percentage that remained stable for the period of 2000 to 2009 (adjusted odds ratio for annual change = 1.006). Most pregnant women reported care from multiple types of clinicians, including family physicians, obstetrician-gynecologists, midwives, nurse practitioners, and physician assistants. There were regional differences in trends in family physician care; pregnant women in the North Central United States increasingly reported care from family physicians, whereas women in the South reported a decline (6.7% annual increase vs 4.7% annual decrease, P ≥.001).

CONCLUSIONS

Trends in family medicine care for pregnant women have remained steady for the nation as a whole, but they differ by region of the United States. Most pregnant women reported care from multiple clinicians, highlighting the importance of care coordination for this patient population.     

Effect of Continuity of Care on Hospital Utilization for Seniors With Multiple Medical Conditions in an Integrated Health Care System

PURPOSE

Lower continuity of care has been associated with higher rates of adverse outcomes for persons with multiple chronic medical conditions. It is unclear, however, whether this relationship also exists within integrated systems that offer high levels of informational continuity through shared electronic health records.

METHODS

We conducted a retrospective cohort study of 12,200 seniors with 3 or more chronic conditions within an integrated delivery system. Continuity of care was calculated using the Continuity of Care Index, which reflects visit concentration with individual clinicians. Using Cox proportional hazards regression permitting continuity to vary monthly until the outcome or censoring event, we separately assessed inpatient admissions and emergency department visits as a function of primary care continuity and specialty care continuity.

RESULTS

After adjusting for covariates (demographics; baseline, primary, and specialty care visits; baseline outcomes; and morbidity burden), greater primary care continuity and greater specialty care continuity were each associated with a lower risk of inpatient admission (respective hazard ratios (95% CIs) = 0.97 (0.96, 0.99) and 0.95 (0.93, 0.98)) and a lower risk of emergency department visits (respective hazard ratios = 0.97 (0.96, 0.98) and 0.98 (0.96, 1.00)). For the subgroup with 3 or more primary care and 3 or more specialty care visits, specialty care continuity (but not primary care continuity) was independently associated with a decreased risk of inpatient admissions (hazard ratio = 0.94 (0.92, 0.97)), and primary care continuity (but not specialty care continuity) was associated with a decreased risk of emergency department visits (hazard ratio = 0.98 (0.96, 1.00)).

CONCLUSIONS

In an integrated delivery system with high informational continuity, greater continuity of care is independently associated with lower hospital utilization for seniors with multiple chronic medical conditions. Different subgroups of patients will benefit from continuity with primary and specialty care clinicians depending on their care needs.     

Associations Between the Continuity of Ambulatory Care of Adult Diabetes Patients in Korea and the Incidence of Macrovascular Complications

Objectives:

The goal of this study was to identify association between the continuity of ambulatory care of diabetes patients in South Korea (hereafter Korea) and the incidence of macrovascular complications of diabetes, using claims data compiled by the National Health Insurance Services of Korea.

Methods:

This study was conducted retrospectively. The subjects of the study were 43 002 patients diagnosed with diabetes in 2007, who were over 30 years of age, and had insurance claim data from 2008. The macrovascular complications of diabetes mellitus were limited to ischemic heart disease and ischemic stroke. We compared the characteristics of the patients in whom macrovascular complications occurred from 2009 to 2012 to the characteristics of the patients who had no such complications. Multiple logistic regression was used to assess the effects of continuity of ambulatory care on diabetic macrovascular complications. The continuity of ambulatory diabetes care was estimated by metrics such as the medication possession ratio, the quarterly continuity of care and the number of clinics that were visited.

Results:

Patients with macrovascular complications showed statistically significant differences regarding sex, age, comorbidities, hypertension, dyslipidemia and continuity of ambulatory diabetes care. Visiting a lower number of clinics reduced the odds ratio for macrovascular complications of diabetes. A medication possession ratio below 80% was associated with an increased odds ratio for macrovascular complications, but this result was of borderline statistical significance.

Conclusions:

Diabetes care by regular health care providers was found to be associated with a lower occurrence of diabetic macrovascular complications. This result has policy implications for the Korean health care system, in which the delivery system does not work properly.     

Adoption,Reach, Implementation,and Maintenance of a Behavioral and Mental Health Assessment in Primary Care

PURPOSE

Guidelines recommend screening patients for unhealthy behaviors and mental health concerns. Health risk assessments can systematically identify patient needs and trigger care. This study seeks to evaluate whether primary care practices can routinely implement such assessments into routine care.

METHODS

As part of a cluster-randomized pragmatic trial, 9 diverse primary care practices implemented My Own Health Report (MOHR)—an electronic or paper-based health behavior and mental health assessment and feedback system paired with counseling and goal setting. We observed how practices integrated MOHR into their workflows, what additional practice staff time it required, and what percentage of patients completed a MOHR assessment (Reach).

RESULTS

Most practices approached (60%) agreed to adopt MOHR. How they implemented MOHR depended on practice resources, informatics capacity, and patient characteristics. Three practices mailed patients invitations to complete MOHR on the Web, 1 called patients and completed MOHR over the telephone, 1 had patients complete MOHR on paper in the office, and 4 had staff help patients complete MOHR on the Web in the office. Overall, 3,591 patients were approached and 1,782 completed MOHR (Reach = 49.6%). Reach varied by implementation strategy with higher reach when MOHR was completed by staff than by patients (71.2% vs 30.2%, P <.001). No practices were able to sustain the complete MOHR assessment without adaptations after study completion. Fielding MOHR increased staff and clinician time an average of 28 minutes per visit.

CONCLUSIONS

Primary care practices can implement health behavior and mental health assessments, but counseling patients effectively requires effort. Practices will need more support to implement and sustain assessments.
