Value and the medical home: effects of transformed primary care.

BACKGROUND: The primary care medical home has been promoted to integrate and improve patient care while reducing healthcare spending, but with little formal study of the model or evidence of its efficacy. ProvenHealth Navigator (PHN), an intensive multidimensional medical home model that addresses care delivery and financing, was introduced into 11 different primary care practices. The goals were to improve the quality, efficiency, and patient experience of care. OBJECTIVE: To evaluate the ability of a medical home model to improve the efficiency of care for Medicare beneficiaries. STUDY DESIGN: Observational study using regression modeling based on preintervention and postintervention data and a propensity-selected control cohort. METHODS: Four years of claims data for Medicare patients at 11 intervention sites and 75 control groups were analyzed to compute hospital admission and readmission rates, and the total cost of care. Regression modeling was used to establish predicted rates and costs in the absence of the intervention. Actual results were compared with predicted results to compute changes attributable to the PHN model. RESULTS: ProvenHealth Navigator was associated with an 18% (P <.01) cumulative reduction in inpatient admissions and a 36% (P = .02) cumulative reduction in readmissions across the total population over the study period. CONCLUSIONS: Investing in the capabilities of primary care practices to serve as medical homes may increase healthcare value by improving the efficiency of care. This study demonstrates that the PHN model is capable of significantly reducing admissions and readmissions for Medicare Advantage members.

A validated value-based model to improve hospital-wide perioperative outcomes: adaptability to combined medical/surgical inpatient cohorts.

OBJECTIVES: Authors hypothesized that building safe hospital systems to improve value-based surgical outcomes is predicated on workflow redesign for dynamic risk stratification, coupled with "real-time" mitigation of risk. We developed a comanagement model for hospitalized surgical cohort, and determined whether this iterative process redesign for surgery will be adaptable to disparate hospital systems and will be beneficial for combined medical/surgical adult inpatients. CONTEXT: Concerns about preventable harm in hospitalized patients have generated a plethora of both, process-driven and outcome-based strategies in US Healthcare. Although comparison between hospitals is a common mechanism to drive quality, other innovative approaches are needed for real-time risk mitigation to improve outcomes. METHODS: Prospective implementation of Surgical Continuum of Care (SCoC) model in hospitals initially for surgery patients; subsequently Continuum of Care (CoC) for medical/surgical population. Redesign of hospital care delivery model: patient cohorting, floor-based team building, and intensivist/hospitalist staffing of progressive care unit (PCU). Work flow redesign for clinical effectiveness: multidisciplinary team rounds, acuity stratified care rounding based on dynamic risk assessment into a novel HAWK (high risk)/DOVE (low risk) patient grouping, intensivist/hospitalist comanagement of surgical patients, and targeted response. STUDY: Pre- and postintervention with concurrent cohort control design. SETTING: Academic medical centers for SCoC and integrated health system hospital for CoC. PATIENT GROUPS: SCoC Pilot Study-Campus A: Preintervention control group 1998-2000, Intervention Group 2001-2004; Campus B: Comparator Control Group 1998-2004. SCoC Validation Study-Campus C: Preintervention Group 2001-2005; Intervention Group 2006-2008. CoC Study-Campus D: Hospital-wide Group 2009. METRICS: Mortality, length of stay (LOS): overall, surgical intensive care unit and PCU, readmission rates, and cost. Case mix index for risk adjustment. RESULTS: Total >100,000 admissions. There was a significant reduction in overall surgical mortality in both, pilot (P < 0.002) and validation (P < 0.02) SCoC studies and overall hospital mortality in the medical/surgical CoC study (risk-adjusted mortality index progressively declined in CoC study from 1.16 pre-CoC to 0.77 six months post-CoC implementation; significant at 75% confidence level). Case mix index was unchanged during study period in each campus. Nested study in validation cohort of hospital-wide versus surgery alone (observed/expected mortality index) demonstrated significant benefit to SCoC in intervention group. The mortality benefit was primarily derived from risk-stratified rounding and actively managing risk prone population in the PCU. Surgical intensive care unit, PCU, and total hospital patient-days significantly decreased in SCoC pilot study (P < 0.05), reflecting enhanced throughput. LOS reduction benefit persisted in SCoC validation and CoC studies. In addition to decreased LOS, cost savings were in PCU (range, $851,511-2,007,388) and top diagnosis-related groups, for example, $452 K/yr for diagnosis-related group 148. CONCLUSIONS: SCoC is patient-centered, outcomes-driven, value-based approach for hospital-wide surgical patient safety. The principles of this value paradigm are adaptable to other hospitals as demonstrated in our longitudinal study in 3 hospital systems, and the initial experience of CoC suggests that this model will have benefit beyond surgical hospital cohort.

Patient experiences and attitudes about access to a patient electronic health care record and linked web messaging.

OBJECTIVE: Patient access to their electronic health care record (EHR) and Web-based communication between patients and providers can potentially improve the quality of health care, but little is known about patients' attitudes toward this combined electronic access. The objective of our study was to evaluate patients' values and perceptions regarding Web-based communication with their primary care providers in the context of access to their electronic health care record. METHODS: We conducted an online survey of 4,282 members of the Geisinger Health System who are registered users of an application (MyChart) that allows patients to communicate electronically with their providers and view selected portions of their EHR. To supplement the survey, we also conducted focus groups with 25 patients who were using the system and conducted one-on-one interviews with ten primary care clinicians. We collected and analyzed data on user satisfaction, ease of use, communication preferences, and the completeness and accuracy of the patient EHR. RESULTS: A total of 4,282 registered patient EHR users were invited to participate in the survey; 1,421 users (33%) completed the survey, 60% of them female. The age distribution of users was as follows: 18 to 30 (5%), 31 to 45 (24%), 46 to 64 (54%), 65 and older (16%). Using a continuous scale from 1 to 100, the majority of users indicated that the system was easy to use (mean scores ranged from 78 to 85) and that their medical record information was complete, accurate, and understandable (mean scores ranged from 65 to 85). Only a minority of users was concerned about the confidentiality of their information or about seeing abnormal test results after receiving only an explanatory electronic message from their provider. Patients preferred e-mail communication for some interactions (e.g., requesting prescription renewals, obtaining general medical information), whereas they preferred in-person communication for others (e.g., getting treatment instructions). Telephone or written communication was never their preferred communication channel. In contrast, physicians were more likely to prefer telephone communication and less likely to prefer e-mail communication. CONCLUSION: Patients' attitudes about the use of Web messaging and online access to their EHR were mostly positive. Patients were satisfied that their medical information was complete and accurate. A minority of patients was mildly concerned about the confidentiality and privacy of their information and about learning of abnormal test results electronically. Clinicians were less positive about using electronic communication than their patients. Patients and clinicians differed substantially regarding their preferred means of communication for different types of interactions.

Implementing advanced access in a group practice network.

The leadership efforts in this complex process emphasize the importance of communication, education and buy-in to implement advanced access in a group practice network. These key components, along with timely feedback, staff support and necessary resources, are especially significant when the end point and the benefits are not immediately apparent to those directly affected by the change. Once these elements are in place, however, any practice has the ability to establish advanced access, increase its patient base and improve its economic performance.
