A Randomized Trial of Peer Coach and Office Staff Support to Reduce Coronary Heart Disease Risk in African-Americans with Uncontrolled Hypertension

OBJECTIVE

Adopting features of the Chronic Care Model may reduce coronary heart disease risk and blood pressure in vulnerable populations. We evaluated a peer and practice team intervention on reduction in 4-year coronary heart disease risk and systolic blood pressure.

DESIGN AND SUBJECTS

A single blind, randomized, controlled trial in two adjacent urban university-affiliated primary care practices. Two hundred eighty African-American subjects aged 40 to 75 with uncontrolled hypertension.

INTERVENTION

Three monthly calls from trained peer patients with well-controlled hypertension and, on alternate months, two practice staff visits to review a personalized 4-year heart disease risk calculator and slide shows about heart disease risks. All subjects received usual physician care and brochures about healthy cooking and heart disease.

MAIN MEASURES

Change in 4-year coronary heart disease risk (primary) and change in systolic blood pressure, both assessed at 6 months.

KEY RESULTS

At baseline, the 136 intervention and 144 control subjects’ mean 4-year coronary heart disease risk did not differ (intervention = 5.8 % and control = 6.4 %, P = 0.39), and their mean systolic blood pressure was the same (140.5 mmHg, p = 0.83). Endpoint data for coronary heart disease were obtained for 69 % of intervention and 82 % of control subjects. After multiple imputation for missing endpoint data, the reduction in risk among all 280 subjects favored the intervention, but was not statistically significant (difference −0.73 %, 95 % confidence interval: -1.54 % to 0.09 %, p = 0.08). Among the 247 subjects with a systolic blood pressure endpoint (85 % of intervention and 91 % of control subjects), more intervention than control subjects achieved a >5 mmHg reduction (61 % versus 45 %, respectively, p = 0.01). After multiple imputation, the absolute reduction in systolic blood pressure was also greater for the intervention group (difference −6.47 mmHg, 95 % confidence interval: −10.69 to −2.25, P = 0.003). One patient died in each study arm.

CONCLUSIONS

Peer patient and office-based behavioral support for African-American patients with uncontrolled hypertension did not result in a significantly greater reduction in coronary heart disease risk but did significantly reduce systolic blood pressure.KEY WORDS: coronary heart disease, hypertension, African American, peer support     

The Return of Bedside Rounds: An Educational Intervention

Background

Bedside rounds have decreased in frequency on teaching services. Perceived barriers toward bedside rounds are inefficiency and patient and house staff lack of preference for this mode of rounding.

Objectives

To evaluate the impact of a bedside rounding intervention on the frequency of bedside rounding, duration of patient encounters and rounding sessions, and patient and resident attitudes toward bedside rounds.

Design

A pre- and postintervention design, with a bedside rounding workshop midway through two consecutive internal medicine rotations, with daily resident interviews, patient surveys, and an end-of-the-year survey given to all Medicine house staff.

Participants

Medicine house staff and medicine patients.

Measures

Frequency of bedside rounds, duration of new patient encounters and rounding sessions, and patient and house staff attitudes regarding bedside rounds.

Results

Forty-four residents completed the bedside rounding workshop. Comparing the preintervention and postintervention phases, bedside rounds increased from <1% to 41% (p < 0.001). The average duration of walk rounding encounters was 16 min, and average duration of bedside rounding encounters was 15 min (p = 0.42). Duration of rounds was 95 and 98 min, respectively (p = 0.52). Patients receiving bedside rounds preferred bedside rounds (99% vs. 83%, p = 0.03) and perceived more time spent at the bedside by their team (p < 0.001). One hundred twelve house staff (71%) responded, with 73% reporting that bedside rounds are better for patient care. House staff performing bedside rounds were less likely to believe that bedside rounds were more educational (53% vs. 78%, p = 0.01).

Conclusions

Bedside rounding increased after an educational intervention, and the time to complete bedside rounding encounters was similar to alternative forms of rounding. Patients preferred bedside rounds and perceived more time spent at the bedside when receiving bedside rounds. Medicine residents performing bedside rounds were less likely to believe bedside rounds were more educational, but all house staff valued the importance of bedside rounding for the delivery of patient care.KEY WORDS: bedside rounds, medical education, patient care     

The Quality of Primary Care in a Country with Universal Health Care Coverage

BACKGROUND

Standard indicators of quality of care have been developed in the United States. Limited information exists about quality of care in countries with universal health care coverage.

OBJECTIVE

To assess the quality of preventive care and care for cardiovascular risk factors in a country with universal health care coverage.

DESIGN AND PARTICIPANTS

Retrospective cohort of a random sample of 1,002 patients aged 50–80 years followed for 2 years from all Swiss university primary care settings.

MAIN MEASURES

We used indicators derived from RAND’s Quality Assessment Tools. Each indicator was scored by dividing the number of episodes when recommended care was delivered by the number of times patients were eligible for indicators. Aggregate scores were calculated by taking into account the number of eligible patients for each indicator.

KEY RESULTS

Overall, patients (44% women) received 69% of recommended preventive care, but rates differed by indicators. Indicators assessing annual blood pressure and weight measurements (both 95%) were more likely to be met than indicators assessing smoking cessation counseling (72%), breast (40%) and colon cancer screening (35%; all p < 0.001 for comparisons with blood pressure and weight measurements). Eighty-three percent of patients received the recommended care for cardiovascular risk factors, including >75% for hypertension, dyslipidemia and diabetes. However, foot examination was performed only in 50% of patients with diabetes. Prevention indicators were more likely to be met in men (72.2% vs 65.3% in women, p < 0.001) and patients <65 years (70.1% vs 68.0% in those ≥65 years, p = 0.047).

CONCLUSIONS

Using standardized tools, these adults received 69% of recommended preventive care and 83% of care for cardiovascular risk factors in Switzerland, a country with universal coverage. Prevention indicator rates were lower for women and the elderly, and for cancer screening. Our study helps pave the way for targeted quality improvement initiatives and broader assessment of health care in Continental Europe.

The Effects of Guided Care on the Perceived Quality of Health Care for Multi-morbid Older Persons: 18-Month Outcomes from a Cluster-Randomized Controlled Trial

BACKGROUND

The quality of health care for older Americans with chronic conditions is suboptimal.

OBJECTIVE

To evaluate the effects of “Guided Care” on patient-reported quality of chronic illness care.

DESIGN

Cluster-randomized controlled trial of Guided Care in 14 primary care teams.

PARTICIPANTS

Older patients of these teams were eligible to participate if, based on analysis of their recent insurance claims, they were at risk for incurring high health-care costs during the coming year. Small teams of physicians and their at-risk older patients were randomized to receive either Guided Care (GC) or usual care (UC).

INTERVENTION

“Guided Care” is designed to enhance the quality of health care by integrating a registered nurse, trained in chronic care, into a primary care practice to work with 2–5 physicians in providing comprehensive chronic care to 50–60 multi-morbid older patients.

MEASUREMENTS

Eighteen months after baseline, interviewers blinded to group assignment administered the Patient Assessment of Chronic Illness Care (PACIC) survey by telephone. Logistic and linear regression was used to evaluate the effect of the intervention on patient-reported quality of chronic illness care.

RESULTS

Of the 13,534 older patients screened, 2,391 (17.7%) were eligible to participate in the study, of which 904 (37.8%) gave informed consent and were cluster-randomized. After 18 months, 95.3% and 92.2% of the GC and UC recipients who remained alive and eligible completed interviews. Compared to UC recipients, GC recipients had twice greater odds of rating their chronic care highly (aOR = 2.13, 95% CI = 1.30–3.50, p = 0.003).

CONCLUSION

Guided Care improves self-reported quality of chronic health care for multi-morbid older persons.KEY WORDS: quality of care, chronic illness, older     

Electronic Tools to Assist with Identification and Counseling for Overweight Patients: a Randomized Controlled Trial

Background

Physicians often do not recognize when their patients are overweight and infrequently counsel them about weight loss.

Objective

To evaluate a set of electronic health record (EHR)-embedded tools to assist with identification and counseling of overweight patients.

Design

Randomized controlled trial.

Participants

Physicians at an academic general internal medicine clinic were randomized to activation of the EHR tools (n = 15) or to usual care (n = 15). Patients of these physicians were included in analyses if they had a body mass index (BMI) between 27 and 29.9 kg/m².

Intervention

The EHR tool set included: a physician point-of-care alert for overweight (BMI 27–29. 9 kg/m²); a counseling template to help physicians counsel patients on action plans; and an order set to facilitate entry of overweight as a diagnosis and to order relevant patient handouts.

Main Measures

Physician documentation of overweight as a problem; documentation of weight-specific counseling; physician perceptions of the EHR tools; patient self-reported progress toward their goals and perspectives about counseling received.

Key Results

Patients of physicians receiving the intervention were more likely than those of usual care physicians to receive a diagnosis of overweight (22% vs. 7%; p = 0.02) and weight-specific counseling (27% vs. 15%; p = 0.02). Most patients receiving counseling in the intervention group reported increased motivation to lose weight (90%) and taking steps toward their goal (93%). Most intervention physicians agreed that the tool alerted them to patients they did not realize were overweight (91%) and improved the effectiveness of their counseling (82%); more than half (55%) reported counseling overweight patients more frequently (55%). However, most physicians used the tool infrequently because of time barriers.

Conclusions

EHR-based alerts and management tools increased documentation of overweight and counseling frequency; the majority of patients for whom the tools were used reported short-term behavior change.KEY WORDS: overweight, counseling, electronic health record     

Do First Opinions Affect Second Opinions?

Background

Second medical opinions have become commonplace and even mandatory in some health-care systems, as variations in diagnosis, treatment or prognosis may emerge among physicians.

Objective

To evaluate whether physicians’ judgment is affected by another medical opinion given to a patient.

Design

Orthopedic surgeons and neurologists filled out questionnaires presenting eight hypothetical clinical scenarios with suggested treatments. One group of physicians (in each specialty) was told what the other physician’s opinion was (study group), and the other group was not told what it was (control group).

Participants

A convenience sample of 332 physicians in Israel: 172 orthopedic surgeons (45.9% of their population) and 160 neurologists (64.0% of their population).

Measurements

Scoring was by choice of less or more interventional treatment in the scenarios. We used χ² tests and repeated measures ANOVA to compare these scores between the two groups. We also fitted a cumulative ordinal regression to account for the dependence within each physician’s responses.

Results

Orthopedic surgeons in the study group chose a more interventionist treatment when the other physician suggested an intervention than those in the control group [F (1, 170) = 4.6, p = 0.03; OR = 1.437, 95% CI 1.115-1.852]. Evaluating this effect separately in each scenario showed that in four out of the eight scenarios, they chose a more interventional treatment when the other physician suggested an intervention (scenario 1, p = 0.039; scenario 2, p < 0.001; scenario 3, p = 0.033; scenario 6, p < 0.001). These effects were insignificant among the neurologists [F (1,158) = 0.44, p = 0.51; OR = 1.087, 95% CI 0.811-1.458]. In both specialties there were no differences in responses by level of clinical experience [orthopedic surgeons: F (2, 166) = 0.752, p = 0.473; neurologists: F (2,154) = 1.951, p = 0.146].

Conclusions

The exploratory survey showed that in some cases physicians’ judgments may be affected by other physicians’ opinions, but unaffected in other cases. Weighing previous opinions may yield a more informed clinical decision, yet physicians may be unintentionally influenced by previous opinions. Second opinion has the potential to improve the clinical decision-making processes, and mechanisms are needed to reconcile discrepant opinions.

Improving Medication Adherence through Graphically Enhanced Interventions in Coronary Heart Disease (IMAGE-CHD): A Randomized Controlled Trial

Background

Up to 50 % of patients do not take medications as prescribed. Interventions to improve adherence are needed, with an understanding of which patients benefit most.

Objective

To test the effect of two low-literacy interventions on medication adherence.

Design

Randomized controlled trial, 2 × 2 factorial design.

Participants

Adults with coronary heart disease in an inner-city primary care clinic.

Interventions

For 1 year, patients received usual care, refill reminder postcards, illustrated daily medication schedules, or both interventions.

Main Measures

The primary outcome was cardiovascular medication refill adherence, assessed by the cumulative medication gap (CMG). Patients with CMG < 0.20 were considered adherent. We assessed the effect of the interventions overall and, post-hoc, in subgroups of interest.

Key Results

Most of the 435 participants were elderly (mean age = 63.7 years), African-American (91 %), and read below the 9th-grade level (78 %). Among the 420 subjects (97 %) for whom CMG could be calculated, 138 (32.9 %) had CMG < 0.20 during follow-up and were considered adherent. Overall, adherence did not differ significantly across treatments: 31.2 % in usual care, 28.3 % with mailed refill reminders, 34.2 % with illustrated medication schedules, and 36.9 % with both interventions. In post-hoc analyses, illustrated medication schedules led to significantly greater odds of adherence among patients who at baseline had more than eight medications (OR = 2.2; 95 % CI, 1.21 to 4.04) or low self-efficacy for managing medications (OR = 2.15; 95 % CI, 1.11 to 4.16); a trend was present among patients who reported non-adherence at baseline (OR = 1.89; 95 % CI, 0.99 to 3.60).

Conclusions

The interventions did not improve adherence overall. Illustrated medication schedules may improve adherence among patients with low self-efficacy, polypharmacy, or baseline non-adherence, though this requires confirmation.KEY WORDS: coronary heart disease, medical adherence, medication management     

Asthma Beliefs Are Associated with Medication Adherence in Older Asthmatics

BACKGROUND

Empirical research and health policies on asthma have focused on children and young adults, even though asthma morbidity and mortality are higher among older asthmatics.

OBJECTIVE

To explore the relationship of asthma-related beliefs and self-reported controller medication adherence in older asthmatics.

DESIGN

An observational study of asthma beliefs and self-management among older adults.

PARTICIPANTS

Asthmatics ages ≥60 years (N = 324, mean age 67.4 ± 6.8, 28 % white, 32 % black, 30 % Hispanic) were recruited from primary care practices in New York City and Chicago.

MAIN MEASURES

Self-reported controller medication adherence was assessed using the Medication Adherence Report Scale. Based on the Common Sense Model of Self-Regulation, patients were asked if they believe they only have asthma with symptoms, their physician can cure their asthma, and if their asthma will persist. Beliefs on the benefit, necessity and concerns of treatment use were also assessed. Multivariate logistic regression was used to examine the association of beliefs with self-reported medication adherence.

KEY RESULTS

The majority (57.0 %) of patients reported poor adherence. Poor self-reported adherence was more common among those with erroneous beliefs about asthma illness and treatments, including the “no symptoms, no asthma” belief (58.7 % vs. 31.7 %, respectively, p < 0.001), “will not always have asthma” belief (34.8 % vs. 12.5 %, p < 0.001), and the “MD can cure asthma” belief (21.7 % vs. 9.6 %, p = 0.01). Adjusting for illness beliefs, treatment beliefs and demographics, patients with a “no symptoms, no asthma” belief had lower odds of having good self-reported adherence (odds ratio [OR] 0.45, 95 % confidence interval [CI] 0.23-0.86), as did those with negative beliefs about the benefits (OR 0.73, 95 % CI 0.57-0.94) and necessity (OR 0.89, 95 % CI 0.83-0.96) of treatment.

CONCLUSIONS

Illness and treatment beliefs have a strong influence on self-reported medication adherence in older asthmatics. Interventions to improve medication adherence in older asthmatics by modifying illness and treatment beliefs warrant study.

Differences in Patient–Provider Communication for Hispanic Compared to Non-Hispanic White Patients in HIV Care

Background

Hispanic Americans with HIV/AIDS experience lower quality care and worse outcomes than non-Hispanic whites. While deficits in patient–provider communication may contribute to these disparities, no studies to date have used audio recordings to examine the communication patterns of Hispanic vs. non-Hispanic white patients with their health care providers.

Objective

To explore differences in patient–provider communication for English-speaking, HIV-infected Hispanic and non-Hispanic white patients.

Design

Cross-sectional analysis.

Setting

Two HIV care sites in the United States (New York and Portland) participating in the Enhancing Communication and HIV Outcomes (ECHO) study.

Subjects

Nineteen HIV providers and 113 of their patients.

Measurements

Patient interviews, provider questionnaires, and audio-recorded, routine, patient–provider encounters coded with the Roter Interaction Analysis System (RIAS).

Results

Providers were mostly non-Hispanic white (68%) and female (63%). Patients were Hispanic (51%), and non-Hispanic white (49%); 20% were female. Visits with Hispanic patients were less patient-centered (0.75 vs. 0.90, p = 0.009), with less psychosocial talk (80 vs. 118 statements, p < 0.001). This pattern was consistent among Hispanics who spoke English very well and those with less English proficiency. There was no association between patient race/ethnicity and visit length, patients’ or providers’ emotional tone, or the total number of patient or provider statements categorized as socioemotional, question-asking, information-giving, or patient activating. Hispanic patients gave higher ratings than whites (AOR 3.05 Hispanic vs. white highest rating of providers’ interpersonal style, 95% CI 1.20-7.74).

Conclusion

In this exploratory study, we found less psychosocial talk in patient–provider encounters with Hispanic compared to white patients. The fact that Hispanic patients rated their visits more positively than whites raises the possibility that these differences in patient–provider interactions may reflect differences in patient preferences and communication style rather than “deficits” in communication. If these findings are replicated in future studies, efforts should be undertaken to understand the reasons underlying them and their impact on the quality and equity of care.KEY WORDS: HIV/AIDS, patient–physician relations, patient–physician communication, health disparities     

Outcomes for Resident-Identified High-Risk Patients and Resident Perspectives of Year-End Continuity Clinic Handoffs

BACKGROUND

Many patients nationwide change their primary care physician (PCP) when internal medicine (IM) residents graduate. Few studies have examined this handoff.

OBJECTIVE

To assess patient outcomes and resident perspectives after the year-end continuity clinic handoff

DESIGN

Retrospective cohort

PARTICIPANTS

Patients who underwent a year-end clinic handoff in July 2010 and a comparison group of all other resident clinic patients from 2009–2011. PGY2 IM residents surveyed from 2010–2011.

MEASUREMENTS

Percent of high-risk patients after the clinic handoff scheduled for an appointment, who saw their assigned PCP, lost to follow-up, or had an acute visit (ED or hospitalization). Perceptions of PGY2 IM residents surveyed after receiving a clinic handoff.

RESULTS

Thirty graduating residents identified 258 high-risk patients. While nearly all patients (97 %) were scheduled, 29 % missed or cancelled their first new PCP visit. Only 44 % of patients saw the correct PCP and six months later, one-fifth were lost to follow-up. Patients not seen by a new PCP after the handoff were less likely to have appropriate follow-up for pending tests (0 % vs. 63 %, P < 0.001). A higher mean no show rate (NSR) was observed among patients who missed their first new PCP visit (22 % vs. 16 % NSR, p < 0.001) and those lost to follow-up (21 % vs. 17 % NSR, p = 0.019). While 47 % of residents worried about missing important data during the handoff, 47 % reported that they do not perceive patients as “theirs” until they are seen by them in clinic.

CONCLUSIONS

While most patients were scheduled for appointments after a clinic handoff, many did not see the correct resident and one-fifth were lost to follow-up. Patients who miss appointments are especially at risk of poor clinic handoff outcomes. Future efforts should improve patient attendance to their first new PCP visit and increase PCP ownership.

Variation in Primary Care Physicians’ Colorectal Cancer Screening Recommendations by Patient Age and Comorbidity

BACKGROUND

Screening patterns among primary care physicians (PCPs) may be influenced by patient age and comorbidity. Colorectal cancer (CRC) screening has little benefit among patients with limited life expectancy.

OBJECTIVE

To characterize the extent to which PCPs modify their recommendations for CRC screening based upon patients’ increasing age and/or worsening comorbidity

DESIGN

Cross-sectional, nationally representative survey.

PARTICIPANTS

The study comprised primary care physicians (n = 1,266) including general internal medicine, family practice, and obstetrics-gynecology physicians.

MAIN MEASURES

Physician CRC screening recommendations among patients of varying age and comorbidity were measured based upon clinical vignettes. Independent variables in adjusted models included physician and practice characteristics.

KEY RESULTS

For an 80-year-old patient with unresectable non-small cell lung cancer (NSCLC), 25 % of PCPs recommended CRC screening. For an 80-year-old patient with ischemic cardiomyopathy (New York Heart Association, Class II), 71 % of PCPs recommended CRC screening. PCPs were more likely to recommend fecal occult blood testing than colonoscopy as the preferred screening modality for a healthy 80-year-old, compared to healthy 50- or 65-year-old patients (19 % vs. 5 % vs. 2 % p < 0.001). For an 80-year-old with unresectable NSCLC, PCPs who were an obstetrics-gynecology physician were more likely to recommend CRC screening, while those with a full electronic medical record were less likely to recommend screening.

CONCLUSIONS

PCPs consider comorbidity when screening older patients for CRC and may change the screening modality from colonoscopy to FOBT. However, a sizable proportion of PCPs would recommend screening for patients with advanced cancer who would not benefit. Understanding the mechanisms underlying these patterns will facilitate the design of future medical education and policy interventions to reduce unnecessary care.

Association Between Race, Depression, and Antiretroviral Therapy Adherence in a Low-Income Population with HIV Infection

Background

Racial disparities exist in many aspects of HIV/AIDS. Comorbid depression adds to the complexity of disease management. However, prior research does not clearly show an association between race and antiretroviral therapy (ART) adherence, or depression and adherence. It is also not known whether the co-existence of depression modifies any racial differences that may exist.

Objective

To examine racial differences in ART adherence and whether the presence of comorbid depression moderates these differences among Medicaid-enrolled HIV-infected patients.

Design

Retrospective cohort study.

Setting

Multi-state Medicaid database (Thomson Reuters MarketScan®).

Participants

Data for 7,034 HIV-infected patients with at least two months of antiretroviral drug claims between 2003 and 2007 were assessed.

Main Measures

Antiretroviral therapy adherence (90 % days covered) were measured for a 12-month period. The main independent variables of interest were race and depression. Other covariates included patient variables, clinical variables (comorbidity and disease severity), and therapy-related variables.

Key Results

In this study sample, over 66 % of patients were of black race, and almost 50 % experienced depression during the study period. A significantly higher portion of non-black patients were able to achieve optimal adherence (≥90 %) compared to black patients (38.6 % vs. 28.7 %, p < 0.001). In fact, black patients had nearly 30 % decreased odds of being optimally adherent to antiretroviral drugs compared to non-black patients (OR = 0.70, 95 % CI: 0.63–0.78), and was unchanged regard less of whether the patient had depression. Antidepressant treatment nearly doubled the odds of optimal ART adherence among patients with depression (OR = 1.92, 95 % CI: 1.12–3.29).

Conclusions

Black race was significantly associated with worse ART adherence, which was not modified by the presence of depression. Under-diagnosis and under-treatment of depression may hinder ART adherence among HIV-infected patients of all races.KEY WORDS: HIV, adherence, depression, race, Medicaid     

Patient Sharing Among Physicians and Costs of Care: A Network Analytic Approach to Care Coordination Using Claims Data

BACKGROUND

Improving care coordination is a national priority and a key focus of health care reforms. However, its measurement and ultimate achievement is challenging.

OBJECTIVE

To test whether patients whose providers frequently share patients with one another—what we term ‘care density’—tend to have lower costs of care and likelihood of hospitalization.

DESIGN

Cohort study

PARTICIPANTS

9,596 patients with congestive heart failure (CHF) and 52,688 with diabetes who received care during 2009. Patients were enrolled in five large, private insurance plans across the US covering employer-sponsored and Medicare Advantage enrollees

MAIN MEASURES

Costs of care, rates of hospitalizations

KEY RESULTS

The average total annual health care cost for patients with CHF was $29,456, and $14,921 for those with diabetes. In risk adjusted analyses, patients with the highest tertile of care density, indicating the highest level of overlap among a patient’s providers, had lower total costs compared to patients in the lowest tertile ($3,310 lower for CHF and $1,502 lower for diabetes, p < 0.001). Lower inpatient costs and rates of hospitalization were found for patients with CHF and diabetes with the highest care density. Additionally, lower outpatient costs and higher pharmacy costs were found for patients with diabetes with the highest care density.

CONCLUSION

Patients treated by sets of physicians who share high numbers of patients tend to have lower costs. Future work is necessary to validate care density as a tool to evaluate care coordination and track the performance of health care systems.

Medical Home Features of VHA Primary Care Clinics and Avoidable Hospitalizations

Background

As the Veterans Health Administration (VHA) reorganizes providers into the patient-centered medical home, questions remain whether this model of care can demonstrate improved patient outcomes and cost savings.

Objective

We measured adoption of medical home features by VHA primary care clinics prior to widespread implementation of the patient-centered medical home and examined if they were associated with lower risk and costs of potentially avoidable hospitalizations.

Design

Secondary patient data was linked to clinic administrative and survey data. Patient and clinic factors in the baseline year (FY2009) were used to predict patient outcomes in the follow-up year.

Participants

2,853,030 patients from 814 VHA primary care clinics

Main Measures

Patient outcomes were measured by hospitalizations for an ambulatory care sensitive condition (ACSC) and their costs and identified through diagnosis and procedure codes from inpatient records. Clinic adoption of medical home features was obtained from the American College of Physicians Medical Home Builder®.

Key Results

The overall mean home builder score in the study clinics was 88 (SD = 13) or 69 %. In adjusted analyses an increase of 10 points in the medical home adoption score in a clinic decreased the odds of an ACSC hospitalization for patients by 3 % (P = 0.032). By component, higher access and scheduling (P = 0.004) and care coordination and transitions (P = 0.020) component scores were related to lower risk of an ACSC hospitalization, and higher population management was related to higher risk (P = 0.023). Total medical home features was not related to ACSC hospitalization costs among patients with at least one (P = 0.074).

Conclusion

Greater adoption of medical home features by VHA primary care clinics was found to be significantly associated with lower risk of avoidable hospitalizations with access and scheduling and care coordination/transitions in care as key factors.KEY WORDS: medical home, avoidable hospitalizations, access, care coordination     

Usual Source of Care and Outcomes Following Acute Myocardial Infarction

Background

The quality of the relationship between a patient and their usual source of care may impact outcomes, especially after an acute clinical event requiring regular follow-up.

Objective

To examine the association between the presence and strength of a usual source of care with mortality and readmission after hospitalization for acute myocardial infarction (AMI).

Design

Prospective Registry Evaluating Myocardial Infarction: Event and Recovery (PREMIER), an observational, 19-center study.

Patients

AMI patients discharged between January 2003 and June 2004.

Main Measures

The strength of the usual source of care was categorized as none, weak, or strong based upon the duration and familiarity of the relationship. Main outcome measures were readmissions and mortality at 6 months and 12 months post-AMI, examined in multivariable analysis adjusting for socio-demographic characteristics, access and barriers to care, financial status, baseline risk factors, and AMI severity.

Key Results

Among 2,454 AMI patients, 441 (18.0 %) reported no usual source of care, whereas 247 (10.0 %) and 1,766 (72.0 %) reported weak and strong usual sources of care, respectively. When compared with a strong usual source of care, adults with no usual source of care had higher 6-month mortality rates [adjusted hazard ratio (aHR) = 3.15, 95 % CI, 1.79–5.52; p < 0.001] and 12-month mortality rates (aHR = 1.92, 95 % CI, 1.19–3.12; p = 0.01); adults with a weak usual source of care trended toward higher mortality at 6 months (aHR = 1.95, 95 % CI, 0.98–3.88; p = 0.06), but not 12 months (p = 0.23). We found no association between the usual source of care and readmissions.

Conclusions

Adults with no or weak usual sources of care have an increased risk for mortality following AMI, but not for readmission.

Moving Forward in GME Reform: A 4 + 1 Model of Resident Ambulatory Training

BACKGROUND

Traditional ambulatory training models have limitations in important domains, including opportunities for residents to learn, fragmentation of care delivery experience, and satisfaction with ambulatory experiences. New models of ambulatory training are needed.

AIM

To compare the impact of a traditional ambulatory training model with a templated 4 + 1 model.

SETTING

A large university-based internal medicine residency using three different training sites: a patient-centered medical home, a hospital-based ambulatory clinic, and community private practices.

PARTICIPANTS

Residents, faculty, and administrative staff.

PROGRAM DESCRIPTION

Development of a templated 4 + 1 model of residency where trainees do not attend to inpatient and outpatient responsibilities simultaneously.

PROGRAM EVALUATION

A mixed-methods analysis of survey and nominal group data measuring three primary outcomes: 1) Perception of learning opportunities and quality of faculty teaching; 2) Reported fragmentation of care delivery experience; 3) Satisfaction with ambulatory experiences. Self-reported empanelment was a secondary outcome. Residents’ learning opportunities increased (p = 0.007) but quality of faculty teaching was unchanged. Participants reported less fragmentation in the care residents provide patients in the inpatient and outpatient setting (p < 0.0001). Satisfaction with ambulatory training improved (p < 0.0001). Self-reported empanelment also increased (p < 0.0001). Results held true for residents, faculty, and staff at all three ambulatory training sites (p < 0.0001).

DISCUSSION

A 4 + 1 model increased resident time in ambulatory continuity clinic, enhanced learning opportunities, reduced fragmentation of care residents provide, and improved satisfaction with ambulatory experiences. More studies of similar models are needed to evaluate effects on additional trainee and patient outcomes.
