The next step towards making use meaningful: electronic information exchange and care coordination across clinicians and delivery sites.

BACKGROUND: Care for patients with chronic conditions often requires coordination between multiple physicians and delivery sites. Electronic Health Record (EHR) use could improve care quality and efficiency in part by facilitating care coordination. OBJECTIVE: We examined the association between EHR use and clinician perceptions of care coordination for patients transferred across clinicians and delivery sites. RESEARCH DESIGN: Repeated surveys of primary care clinicians during the staggered implementation of an outpatient EHR (2005-2008), followed by an integrated inpatient EHR (2006-2010). We measured the association between EHR use stages (no use, outpatient EHR only, and integrated inpatient-outpatient EHR) and care coordination using logistic regression, adjusting for clinician characteristics, study year, and medical center. SUBJECTS: Adult primary care clinicians in a large Integrated Delivery System. MEASURES: Three measures of clinician-reported care coordination for patient care transferred across clinicians (eg, from specialist to primary care team) and across delivery sites (eg, from the hospital to outpatient care). RESULTS: Outpatient EHR use was associated with higher reports of access to complete and timely clinical information and higher agreement on clinician roles and responsibilities for patients transferred across clinicians, but not for patients transferred across delivery sites. Use of the integrated outpatient-inpatient EHR was associated with higher reports of access to timely and complete clinical information, clinician agreement on the patient's treatment plan for patients transferred across delivery sites, and with all coordination measures for patients transferred across clinicians. CONCLUSION: Use of an integrated EHR with health information exchange across delivery settings improved patient care coordination.

Manual and automated methods for identifying potentially preventable readmissions: a comparison in a large healthcare system.

BACKGROUND: Identification of potentially preventable readmissions is typically accomplished through manual review or automated classification. Little is known about the concordance of these methods. METHODS: We manually reviewed 459 30-day, all-cause readmissions at 18 Kaiser Permanente Northern California hospitals, determining potential preventability through a four-step manual review process that included a chart review tool, interviews with patients, their families, and treating providers, and nurse reviewer and physician evaluation of findings and determination of preventability on a five-point scale. We reassessed the same readmissions with 3 M's Potentially Preventable Readmission (PPR) software. We examined between-method agreement and the specificity and sensitivity of the PPR software using manual review as the reference. RESULTS: Automated classification and manual review respectively identified 78% (358) and 47% (227) of readmissions as potentially preventable. Overall, the methods agreed about the preventability of 56% (258) of readmissions. Using manual review as the reference, the sensitivity of PPR was 85% and specificity was 28%. CONCLUSIONS: Concordance between methods was not high enough to replace manual review with automated classification as the primary method of identifying preventable 30-day, all-cause readmission for quality improvement purposes.

Complete care at Kaiser Permanente: transforming chronic and preventive care.

BACKGROUND: In 2004 Kaiser Permanente Southern California (KPSC) recognized the potential to improve the quality of care. Healthcare Effectiveness Data and Information Set (HEDIS) performance was below what regional leadership aspired to achieve, exceeding the 90th national percentile on only 15 of 34 measures. Beginning in 2005 regional leadership identified several system opportunities to enhance evidence-based, person-focused care. DEVELOPMENT OF COMPLETE CARE: KPSC developed and implemented a comprehensive delivery system redesign and expanded and integrated existing clinical information systems, decision support, work flows, and self-management support-collectively referred to as Complete Care. The goal of Complete Care is to transform care for healthy members, those with chronic conditions, and those with multiple comorbidities. To date, KPSC has applied Complete Care to 26 chronic conditions and areas of preventive and wellness care. Implemented in all care settings and optimizing the roles of all health care team members to maximal scope of practice, Complete Care provides evidence-based, person-focused care addressing a large set of protocol-based health needs for every individual during every encounter within the health care system. RESULTS: On 51 HEDIS metrics, KPSC improvement using Complete Care averaged 13.0%, compared with 5.5% improvement in the national HEDIS 50th percentile. CONCLUSION: Implementation of Complete Care at KPSC was followed by six-year quality gains that outpaced changes in the HEDIS national percentiles for many measures. Additional care gaps have been included in proactive office encounter checklists; these relate to elder care, advance directives, posthospital care, immunizations, health maintenance, and pregnancy care.

Factors contributing to all-cause 30-day readmissions: a structured case series across 18 hospitals.

OBJECTIVE: To understand factors leading to all-cause 30-day readmissions in a community hospital population. RESEARCH DESIGN: Structured case series of 537 readmissions using chart reviews, interviews with treating physicians, patients and family caregivers, and overall case assessment by a nurse-physician team. SETTING: Eighteen Kaiser Permanente Northern California hospitals. RESULTS: Forty-seven percent (250) of readmissions were assessed as potentially preventable; 11% (55) were assessed as very or completely preventable; and 36% (195) as slightly or moderately preventable. On average, 8.7 factors contributed to each potentially preventable readmission. Factors were related to care during the index stay (in 143 cases, 57% of potentially preventable readmissions), the discharge process (168, 67%), and follow-up care (197, 79%). Missed opportunities to prevent readmissions were also related to quality improvement focus areas: transitions care planning and care coordination, clinical care, logistics of follow-up care, advance care planning and end-of-life care, and medication management. CONCLUSIONS: Multiple factors contributed to potentially preventable readmissions in an integrated health care system with low baseline readmission rates. Reducing all-cause 30-day readmissions may require a comprehensive approach addressing these areas. Future quality improvement efforts and research should identify existing and new tactics that can best prevent readmissions by addressing missed opportunities we identified.

Self-management support to people with type 2 diabetes - a comparative study of Kaiser Permanente and the Danish Healthcare System.

BACKGROUND: Self-management support is considered to be an essential part of diabetes care. However, the implementation of self-management support within healthcare settings has appeared to be challenging and there is increased interest in "real world" best practice examples to guide policy efforts. In order to explore how different approaches to diabetes care and differences in management structure influence the provision of SMS we selected two healthcare systems that have shown to be comparable in terms of budget, benefits and entitlements. We compared the extent of SMS provided and the self-management behaviors of people living with diabetes in Kaiser Permanente (KP) and the Danish Healthcare System (DHS). METHODS: Self-administered questionnaires were used to collect data from a random sample of 2,536 individuals with DM from KP and the DHS in 2006-2007 to compare the level of SMS provided in the two systems and identify disparities associated with educational attainment. The response rates were 75 % in the DHS and 56 % in KP. After adjusting for gender, age, educational level, and HbA1c level, multiple linear regression analyses determined the level of SMS provided and identified disparities associated with educational attainment. RESULTS: Receipt of SMS varied substantially between the two systems. More people with diabetes in KP reported receiving all types of SMS and use of SMS tools compared to the DHS (p < .0001). Less than half of all respondents reported taking diabetes medication as prescribed and following national guidelines for exercise. CONCLUSIONS: Despite better SMS support in KP compared to the DHS, self-management remains an under-supported area of care for people receiving care for diabetes in the two health systems. Our study thereby suggests opportunity for improvements especially within the Danish healthcare system and systems adopting similar SMS support strategies.

Factors Influencing Patient Satisfaction With Care and Surgical Outcomes for Total Hip and Knee Replacement.

INTRODUCTION: Although patient satisfaction with total joint arthroplasty has been a well-measured outcome, little is known about how preadmission and post-discharge care experiences affect patients' rating of satisfaction. OBJECTIVE: This work aimed to identify actionable factors associated with better ratings of overall care and surgical results. METHODS: A 36-item survey assessing care in the preoperative, perioperative, and post-discharge phases of care and across all phases was mailed to 7,031 patients who underwent primary unilateral elective total hip arthroplasty and total knee arthroplasty in 2018. Exploratory factor analysis identified 7 actionable domains. Stepwise logistic regression models identified domains associated with ratings of overall care and satisfaction with surgical outcome. RESULTS: Of the 3,026 (43%) patients who returned the survey; 2,814 (93%) rated their overall experience of care as very good or excellent and satisfaction with surgical results as ≥ 7 on a 10-point scale. In exploratory factor analysis, four factors predicted higher ratings of both overall care and surgical outcome: knowing what to do with symptoms and pain during recovery (factor 1), self-reported health (factor 3), knowing what to expect before surgery (factor 4), and shared decision making (factor 6). Coordinated information among providers (factor 2), home health experience (factor 5), and patient-provider relationships (factor 7) also predicted overall care ratings. CONCLUSION: Patient-centered quality improvement in total joint replacement care requires thinking of care across the entire episode, including before and after the hospital stay for surgery, in addition to perioperative care. The actionable factors identified from this study can be incorporated into total joint replacement care to improve patients' satisfaction with overall care and surgical results.

Effective population management practices in diabetes care - an observational study.

BACKGROUND: Ensuring that evidence based medicine reaches patients with diabetes in the US and internationally is challenging. The chronic care model includes evidence based management practices which support evidence based care. However, despite numerous studies, it is unclear which practices are most effective. Few studies assess the effect of simultaneous practices implemented to varying degrees. The present study evaluates the effect of fifteen practices applied concurrently and takes variation in implementation levels into account while assessing the impact of diabetes care management practices on glycemic and lipid monitoring. METHODS: Fifteen management practices were identified. Implementation levels of the practices in 41 medical centres caring for 553,556 adults with diabetes were assessed from structured interviews with key informants. Stepwise logistic regression models with management practices as explanatory variables and glycemic and lipid monitoring as outcome variables were used to identify the diabetes care practices most associated with high performance. RESULTS: Of the 15 practices studied, only provider alerts were significantly associated with higher glycemic and lipid monitoring rates. The odds ratio for glycemic monitoring was 4.07 (p < 0.00001); the odds ratio for lipid monitoring was 1.63 (p < 0.006). Weaker associations were found between action plans and glycemic monitoring (odds ratio = 1.44; p < 0.03) and between guideline distribution and training and lipid monitoring (odds ratio = 1.46; p < 0.03). The covariates of gender, age, cardiac disease and depression significantly affected monitoring rates. CONCLUSIONS: Of fifteen diabetes care management practices, our data indicate that high performance is most associated with provider alerts and more weakly associated with action plans and with guideline distribution and training. Lack of convergence in the literature on effective care management practices suggests that factors contributing to high performance may be highly context-dependent or that the factors involved may be too numerous or their implementation too nuanced to be reliably identified in observational studies.

Is the Kaiser Permanente model superior in terms of clinical integration?: a comparative study of Kaiser Permanente, Northern California and the Danish healthcare system.

BACKGROUND: Integration of medical care across clinicians and settings could enhance the quality of care for patients. To date, there is limited data on the levels of integration in practice. Our objective was to compare primary care clinicians' perceptions of clinical integration and three sub-aspects in two healthcare systems: Kaiser Permanente, Northern California (KPNC) and the Danish healthcare system (DHS). Further, we examined the associations between specific organizational factors and clinical integration within each system. METHODS: Comparable questionnaires were sent to a random sample of primary care clinicians in KPNC (n = 1103) and general practitioners in DHS (n = 700). Data were analysed using multiple logistic regression models. RESULTS: More clinicians in KPNC perceived to be part of a clinical integrated environment than did general practitioners in the DHS (OR = 3.06, 95% CI: 2.28, 4.12). Further, more KPNC clinicians reported timeliness of information transfer (OR = 2.25, 95% CI: 1.62, 3.13), agreement on roles and responsibilities (OR = 1.79, 95% CI: 1.30, 2.47) and established coordination mechanisms in place to ensure effective handoffs (OR = 6.80, 95% CI: 4.60, 10.06). None of the considered organizational factors in the sub-country analysis explained a substantial proportion of the variation in clinical integration. CONCLUSIONS: More primary care clinicians in KPNC reported clinical integration than did general practitioners in the DHS. Focused measures of clinical integration are needed to develop the field of clinical integration and to create the scientific foundation to guide managers searching for evidence based approaches.

Assessing End-of-Life Care across Settings in an Integrated Health Care Delivery System.

Objective: To systematically capture patient- and family-centered data to understand variability and opportunities in end-of-life care delivery across settings in an integrated health care delivery system. Background: Improving the quality of end-of-life care requires assessing patient and family experiences across settings where care occurs, but we found no existing instrument suitable for this purpose. Methods: We conducted a cross-sectional survey with 10,308 surviving respondents (usually next of kin) of decedents in five Kaiser Permanente operating regions. The survey included eight items from an existing validated survey and three original items. Results: The overall response rate was 26% (2631). Most respondents reported that they were knowledgeable about decedents' end-of-life care and preferences. Across regions, 80% of respondents reported overall end-of-life care as excellent or very good. The proportion of excellent and very good responses was 74-84% across regions for items assessing attributes of end-of-life care, with statistically significant differences (p < 0.05). The proportion of positive responses was 69-89%. Overall, end-of-life care was rated as excellent or very good for a greater proportion of patients who received palliative care, hospice care, or both (78-82%), compared to those who did not (69%, p < 0.05 for all). Discussion: Regions are using data to inform end-of-life care initiatives. Assessing patient and family experiences of end-of-life care across settings with a single survey was feasible and provided valuable information supporting quality improvement. The survey met our need for a general purpose survey on end-of-life care experience.

Incidence, clinical outcomes, and transmission dynamics of severe coronavirus disease 2019 in California and Washington: prospective cohort study.

OBJECTIVE: To understand the epidemiology and burden of severe coronavirus disease 2019 (covid-19) during the first epidemic wave on the west coast of the United States. DESIGN: Prospective cohort study. SETTING: Kaiser Permanente integrated healthcare delivery systems serving populations in northern California, southern California, and Washington state. PARTICIPANTS: 1840 people with a first acute hospital admission for confirmed covid-19 by 22 April 2020, among 9 596 321 healthcare plan enrollees. Analyses of hospital length of stay and clinical outcomes included 1328 people admitted by 9 April 2020 (534 in northern California, 711 in southern California, and 83 in Washington). MAIN OUTCOME MEASURES: Cumulative incidence of first acute hospital admission for confirmed covid-19, and subsequent probabilities of admission to an intensive care unit (ICU) and mortality, as well as duration of hospital stay and ICU stay. The effective reproduction number (RE ) describing transmission dynamics was estimated for each region. RESULTS: As of 22 April 2020, cumulative incidences of a first acute hospital admission for covid-19 were 15.6 per 100 000 cohort members in northern California, 23.3 per 100 000 in southern California, and 14.7 per 100 000 in Washington. Accounting for censoring of incomplete hospital stays among those admitted by 9 April 2020, the estimated median duration of stay among survivors was 9.3 days (with 95% staying 0.8 to 32.9 days) and among non-survivors was 12.7 days (1.6 to 37.7 days). The censoring adjusted probability of ICU admission for male patients was 48.5% (95% confidence interval 41.8% to 56.3%) and for female patients was 32.0% (26.6% to 38.4%). For patients requiring critical care, the median duration of ICU stay was 10.6 days (with 95% staying 1.3 to 30.8 days). The censoring adjusted case fatality ratio was 23.5% (95% confidence interval 19.6% to 28.2%) among male inpatients and 14.9% (11.8% to 18.6%) among female inpatients; mortality risk increased with age for both male and female patients. Reductions in RE were identified over the study period within each region. CONCLUSIONS: Among residents of California and Washington state enrolled in Kaiser Permanente healthcare plans who were admitted to hospital with covid-19, the probabilities of ICU admission, of long hospital stay, and of mortality were identified to be high. Incidence rates of new hospital admissions have stabilized or declined in conjunction with implementation of social distancing interventions.

Coordination of diabetes care in four delivery models using an electronic health record.

BACKGROUND: Care coordination is essential to effective chronic care, but knowledge of processes by which health care professionals coordinate their activities when caring for chronically ill patients is limited. Electronic health records (EHRs) are expected to facilitate coordination of care, but whether they do so completely-and under what conditions-is not well understood. OBJECTIVES: To identify processes by which providers worked together to provide care using an EHR and to examine factors supporting coordination of care. DESIGN: Qualitative multiple case study in 4 sites with diverse care delivery models, using semi-structured in-person interviews with 46 physicians and staff and telephone interviews with 65 adult patients with diabetes. SETTING: Four Kaiser Permanente medical centers. RESULTS: Across all care models, physicians and staff acted sequentially as loosely coupled links in a chain, relying on EHR-enabled informational continuity to coordinate care. Of providers, 94% were highly satisfied with the availability of patient information, and 89% of patients were satisfied or very satisfied with the coordination of their care. However, 6 of 65 patients described experiences of uncoordinated care, and 5 of 12 primary care providers identified coordination issues. These pertained to unreconciled differences of opinion, conflicting role expectations, and discipline-specific views of patient needs. CONCLUSIONS: Diabetes care can be coordinated across providers, but some coordination issues persist despite the informational continuity provided by an EHR. Multidisciplinary care teams should be alert to potential coordination challenges, and possible solutions should be explored, including longitudinal care planning with structured communications at key points in care.

Rapid spread of complex change: a case study in inpatient palliative care.

BACKGROUND: Based on positive findings from a randomized controlled trial, Kaiser Permanente's national executive leadership group set an expectation that all Kaiser Permanente and partner hospitals would implement a consultative model of interdisciplinary, inpatient-based palliative care (IPC). Within one year, the number of IPC consultations program-wide increased almost tenfold from baseline, and the number of teams nearly doubled. We report here results from a qualitative evaluation of the IPC initiative after a year of implementation; our purpose was to understand factors supporting or impeding the rapid and consistent spread of a complex program. METHODS: Quality improvement study using a case study design and qualitative analysis of in-depth semi-structured interviews with 36 national, regional, and local leaders. RESULTS: Compelling evidence of impacts on patient satisfaction and quality of care generated 'pull' among adopters, expressed as a remarkably high degree of conviction about the value of the model. Broad leadership agreement gave rise to sponsorship and support that permeated the organization. A robust social network promoted knowledge exchange and built on an existing network with a strong interest in palliative care. Resource constraints, pre-existing programs of a different model, and ambiguous accountability for implementation impeded spread. CONCLUSIONS: A complex, hospital-based, interdisciplinary intervention in a large health care organization spread rapidly due to a synergy between organizational 'push' strategies and grassroots-level pull. The combination of push and pull may be especially important when the organizational context or the practice to be spread is complex.

Patient Assessment of Chronic Illness Care (PACIC) and improved patient-centered outcomes for chronic conditions.

BACKGROUND: The Patient Assessment of Chronic Illness Care (PACIC) has potential for use as a patient-centered measure of the implementation of the Chronic Care Model (CCM), but there is little research on the relationship between the PACIC and important behavioral and quality measures for patients with chronic conditions. OBJECTIVE: To examine the relationship between PACIC scores and self-management behaviors, patient rating of their health care, and self-reported quality of life. DESIGN: Cross-sectional survey with a 61% response rate. PARTICIPANTS: Included in the survey were 4,108 adults with diabetes, chronic pain, heart failure, asthma, or coronary artery disease in the Kaiser Permanente Medical Care program across 7 regions nationally. MEASUREMENTS: The PACIC was the main independent variable. Dependent variables included use of self-management resources, self-management behaviors such as regular exercise, self-reported adherence to medications, patient rating of their health care, and quality of life. RESULTS: PACIC scores were significantly, positively associated with all measures (odds ratio [ORs] ranging from 1.20 to 2.36) with the exception of self-reported medication adherence. CONCLUSIONS: Use of the PACIC, a practical, patient-level assessment of CCM implementation, could be an important tool for health systems and other stakeholders looking to improve the quality of chronic disease care.

A retrospective analysis of health systems in Denmark and Kaiser Permanente.

BACKGROUND: To inform Danish health care reform efforts, we compared health care system inputs and performance and assessed the usefulness of these comparisons for informing policy. METHODS: Retrospective analysis of secondary data in the Danish Health Care System (DHS) with 5.3 million citizens and the Kaiser Permanente integrated delivery system (KP) with 6.1 million members in California. We used secondary data to compare population characteristics, professional staff, delivery structure, utilisation and quality measures, and direct costs. We adjusted the cost data to increase comparability. RESULTS: A higher percentage of KP patients had chronic conditions than did patients in the DHS: 6.3% vs. 2.8% (diabetes) and 19% vs. 8.5% (hypertension), respectively. KP had fewer total physicians and staff compared to DHS, with 134 physicians/100,000 individuals versus 311 physicians/100,000 individuals. KP physicians are salaried employees; in contrast, DHS primary care physicians own and run their practices, remunerated by a mixture of capitation and fee-for-service payments, while most specialists are employed at largely public hospitals. Hospitalisation rates and lengths of stay (LOS) were lower in KP, with mean acute admission LOS of 3.9 days versus 6.0 days in the DHS, and, for stroke admissions, 4.2 days versus 23 days. Screening rates also differed: 93% of KP members with diabetes received retinal screening; only 46% of patients in the DHS with diabetes did. Per capita operating expenditures were PPP$1,951 (KP) and PPP $1,845 (DHS). CONCLUSION: Compared to the DHS, KP had a population with more documented disease and higher operating costs, while employing fewer physicians and resources like hospital beds. Observed quality measures also appear higher in KP. However, simple comparisons between health care systems may have limited value without detailed information on mechanisms underlying differences or identifying translatable care improvement strategies. We suggest items for more in-depth analyses that could improve the interpretability of findings and help identify lessons that can be transferred.

Perceptions and Experience of Patients, Staff, and Clinicians with Social Needs Assessment.

CONTEXT: Assessment of social needs is expanding at Kaiser Permanente (KP), but little is known about how members and clinicians experience the incorporation of social needs into health care. OBJECTIVE: To assess how KP members and clinicians experience social needs assessments incorporated into care. DESIGN: Qualitative and descriptive analysis of data from member and clinician focus groups, interviews, and surveys among 68 members and family caregivers who had participated in social needs assessment programs and 90 clinicians and staff in the KP Colorado, Georgia, Northern California, Northwest, and Southern California Regions. MAIN OUTCOME MEASURES: Members' and clinicians' perceptions and experiences of social needs assessment. RESULTS: Members and clinicians understood the impact of social needs on health and why a health care system representative would ask about food, housing, transportation, and other social needs. Members and clinicians supported social needs assessment at KP and agreed that KP should help address identified social needs. However, both groups emphasized the importance of assessments yielding actionable information. Members were also concerned about how the information would be used and by whom. CONCLUSION: Our findings support the continuing assessment of social needs at KP and identify issues that require attention as it expands. Assessment should not outpace organizational capacity to connect members with resources. Careful attention to communications is required because members may be uncertain or concerned about the purpose of the assessment and the dissemination of sensitive information. Messaging should assure members about data use and dissemination and what they can expect after screening.

Is patient activation associated with outcomes of care for adults with chronic conditions?

We examined the patient activation measure's (PAM's) association with process and health outcomes among adults with chronic conditions. Patients with high PAM scores were significantly more likely to perform self-management behaviors, use self-management services, and report high medication adherence, compared to patients with the lowest PAM scores. This population was 10 times more likely to report high patient-satisfaction scores, 5 times more likely to report high quality-of-life scores, and reported significantly higher physical and mental functional status scores, compared to those with the lowest scores. These results suggest that PAM scores are associated with key process and health outcome measures.

How well do the HEDIS asthma inclusion criteria identify persistent asthma?

OBJECTIVES: (1) To determine if the Health Plan Employer Data and Information Set (HEDIS) asthma inclusion criteria consistently identify persistent asthma on a year-to-year basis and (2) to explore whether variation in the number of years of qualification is associated with medication and resource utilization outcomes. STUDY DESIGN: Retrospective observational study. METHODS: We identified 132 414 patients in a large healthcare program who were included in 1 or more HEDIS persistent asthma cohorts between 1999 and 2002 and who had continuous insurance and pharmacy benefit coverage for the entire 4-year observation period. Medication, emergency department, and hospital use in 2002 was identified using electronic claims and pharmacy information. RESULTS: Overall, 47.9% of the patients were identified as having persistent asthma in only 1 of 4 years, 40.8% had at least 2 consecutive years, and 28.2% had at least 3 consecutive years. In bivariate and multivariate analyses, more consecutive years of HEDIS persistent asthma qualification significantly increased the likelihood of frequent short-acting b-agonist use, inhaled antiinflammatory corticosteroid use, at least 1 emergency department visit, and at least 1 hospitalization. The strongest relationship was for 3 or more consecutive years of HEDIS qualification. CONCLUSIONS: A significant portion of the HEDIS persistent asthma cohort does not qualify on a year-to-year basis, suggesting that the current 1-year qualification period or the underlying administrative case definition for persistent asthma may be suboptimal. Further clinical validation studies are needed to determine the optimal criteria for a more useful HEDIS persistent asthma case definition.

Association of patient-reported care coordination with patient satisfaction.

Little is known about the relationship between care coordination directly assessed from the patient's perspective and patient satisfaction. This study applied multiple logistic regression models to examine associations between patient-reported care coordination and patient satisfaction among 1367 patients with diabetes. We found robust positive relationship between care coordination and patient satisfaction with overall chronic care (odds ratio [OR] = 1.78), one's regular doctor (OR = 1.85), and the way care was organized (OR = 1.98). Implications for health plans, providers, and future research are discussed.

The impact of electronic health records and teamwork on diabetes care quality.

OBJECTIVES: Evidence of the impact electronic health records (EHRs) have on clinical outcomes remains mixed. The impact of EHRs likely depends on the organizational context in which they are used. This study focuses on one aspect of the organizational context: cohesion of primary care teams. We examined whether team cohesion among primary care team members changed the association between EHR use and changes in clinical outcomes for patients with diabetes. STUDY DESIGN: Retrospective longitudinal study. METHODS: We combined provider-reported primary care team cohesion with lab values for patients with diabetes collected during the staggered EHR implementation (2005-2009). We used multivariate regression models with patient-level fixed effects to assess whether team cohesion levels changed the association between outpatient EHR use and clinical outcomes for patients with diabetes. Subjects were comprised of 80,611 patients with diabetes, in whom we measured changes in glycated hemoglobin (A1C) and low-density lipoprotein cholesterol (LDL-C). RESULTS: For A1C, EHR use was associated with an average decrease of 0.11% for patients with higher-cohesion primary care teams compared with a decrease of 0.08% for patients with lower-cohesion teams (difference = 0.02% in A1C; 95% CI, 0.01%-0.03%). For LDL-C, EHR use was associated with a decrease of 2.15 mg/dL for patients with higher-cohesion primary care teams compared with a decrease of 1.42 mg/dL for patients with lower-cohesion teams (difference = 0.73 mg/dL; 95% CI, 0.41-1.11 mg/dL). CONCLUSIONS: Patients cared for by higher cohesion primary care teams experienced modest but statistically significantly greater EHR-related health outcome improvements, compared with patients cared for by providers practicing in lower cohesion teams.
