Categories of Practice Transformation in a Statewide Medical Home Pilot and their Association with Medical Home Recognition

BACKGROUND

Healthcare purchasers have created financial incentives for primary care practices to achieve medical home recognition. Little is known about how changes in practice structure vary across practices or relate to medical home recognition.

OBJECTIVE

We aimed to characterize patterns of structural change among primary care practices participating in a statewide medical home pilot.

DESIGN

We surveyed practices at baseline and year 3 of the pilot, measured associations between changes in structural capabilities and National Committee for Quality Assurance (NCQA) medical home recognition levels, and used latent class analysis to identify distinct classes of structural transformation.

PARTICIPANTS

Eighty-one practices that completed surveys at baseline and year 3 participated in the study.

MAIN MEASURES

Study measures included overall structural capability score (mean of 69 capabilities); eight structural subscale scores; and NCQA recognition levels.

RESULTS

Practices achieving higher year-3 NCQA recognition levels had higher overall structural capability scores at baseline (Level 1: 28.4 % of surveyed capabilities, Level 2: 40.9 %, Level 3: 48.7 %; p value = 0.001). We found no association between NCQA recognition level and change in structural capability scores (Level 1: 33.2 % increase, Level 2: 30.8 %, Level 3: 33.7 %; p value = 0.88). There were four classes of practice transformation: 27 % of practices underwent “minimal” transformation (changing little on any scale); 20 % underwent “provider-facing” transformation (adopting electronic health records, patient registries, and care reminders); 26 % underwent “patient-facing” transformation (adopting shared systems for communicating with patients, care managers, referral to community resources, and after-hours care); and 26 % underwent “broad” transformation (highest or second-highest levels of transformation on each subscale).

Conclusions and Relevance

In a large, state-based medical home pilot, multiple types of practice transformation could be distinguished, and higher levels of medical home recognition were associated with practices’ capabilities at baseline, rather than transformation over time. By identifying and explicitly incentivizing the most effective types of transformation, program designers may improve the effectiveness of medical home interventions.KEY WORDS: patient-centered medical home, structural transformation, primary care     

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     

Association Between Study Quality and Publication Rates of Medical Education Abstracts Presented at the Society of General Internal Medicine Annual Meeting

Background

Studies reveal that 44.5 % of abstracts presented at national meetings are subsequently published in indexed journals, with lower rates for abstracts of medical education scholarship.

Objective

We sought to determine whether the quality of medical education abstracts is associated with subsequent publication in indexed journals, and to compare the quality of medical education abstracts presented as scientific abstracts versus innovations in medical education (IME).

Design

Retrospective cohort study.

Participants

Medical education abstracts presented at the Society of General Internal Medicine (SGIM) 2009 annual meeting.

Main Measures

Publication rates were measured using database searches for full-text publications through December 2013. Quality was assessed using the validated Medical Education Research Study Quality Instrument (MERSQI).

Key Results

Overall, 64 (44 %) medical education abstracts presented at the 2009 SGIM annual meeting were subsequently published in indexed medical journals. The MERSQI demonstrated good inter-rater reliability (intraclass correlation range, 0.77–1.00) for grading the quality of medical education abstracts. MERSQI scores were higher for published versus unpublished abstracts (9.59 vs. 8.81, p = 0.03). Abstracts with a MERSQI score of 10 or greater were more likely to be published (OR 3.18, 95 % CI 1.47–6.89, p = 0.003). ). MERSQI scores were higher for scientific versus IME abstracts (9.88 vs. 8.31, p < 0.001). Publication rates were higher for scientific abstracts (42 [66 %] vs. 37 [46 %], p = 0.02) and oral presentations (15 [23 %] vs. 6 [8 %], p = 0.01).

Conclusions

The publication rate of medical education abstracts presented at the 2009 SGIM annual meeting was similar to reported publication rates for biomedical research abstracts, but higher than publication rates reported for medical education abstracts. MERSQI scores were associated with higher abstract publication rates, suggesting that attention to measures of quality—such as sampling, instrument validity, and data analysis—may improve the likelihood that medical education abstracts will be published.KEY WORDS: medical education, medical education research, quality, publication     

Usual Primary Care Provider Characteristics of a Patient-Centered Medical Home and Mental Health Service Use

BACKGROUND

The benefits of the patient-centered medical home (PCMH) over and above that of a usual source of medical care have yet to be determined, particularly for adults with mental health disorders.

OBJECTIVE

To examine qualities of a usual provider that align with PCMH goals of access, comprehensiveness, and patient-centered care, and to determine whether PCMH qualities in a usual provider are associated with the use of mental health services (MHS).

DESIGN

Using national data from the Medical Expenditure Panel Survey, we conducted a lagged cross-sectional study of MHS use subsequent to participant reports of psychological distress and usual provider and practice characteristics.

PARTICIPANTS

A total of 2,358 adults, aged 18–64 years, met the criteria for serious psychological distress and reported on their usual provider and practice characteristics.

MAIN MEASURES

We defined “usual provider” as a primary care provider/practice, and “PCMH provider” as a usual provider that delivered accessible, comprehensive, patient-centered care as determined by patient self-reporting. The dependent variable, MHS, included self-reported mental health visits to a primary care provider or mental health specialist, counseling, and psychiatric medication treatment over a period of 1 year.

RESULTS

Participants with a usual provider were significantly more likely than those with no usual provider to have experienced a primary care mental health visit (marginal effect [ME] = 8.5, 95 % CI = 3.2–13.8) and to have received psychiatric medication (ME = 15.5, 95 % CI = 9.4–21.5). Participants with a PCMH were additionally more likely than those with no usual provider to visit a mental health specialist (ME = 7.6, 95 % CI = 0.7–14.4) and receive mental health counseling (ME = 8.5, 95 % CI = 1.5–15.6). Among those who reported having had any type of mental health visit, participants with a PCMH were more likely to have received mental health counseling than those with only a usual provider (ME = 10.0, 95 % CI = 1.0–19.0).

CONCLUSIONS

Access to a usual provider is associated with increased receipt of needed MHS. Patients who have a usual provider with PCMH qualities are more likely to receive mental health counseling.KEY WORDS: patient-centered medical home, primary care, mental health services, Affordable Care Act, race     

US Medical Student Performance on the NBME Subject Examination in Internal Medicine: Do Clerkship Sequence and Clerkship Length Matter?

BACKGROUND

Prior to graduation, US medical students are required to complete clinical clerkship rotations, most commonly in the specialty areas of family medicine, internal medicine, obstetrics and gynecology (ob/gyn), pediatrics, psychiatry, and surgery. Within a school, the sequence in which students complete these clerkships varies. In addition, the length of these rotations varies, both within a school for different clerkships and between schools for the same clerkship.

OBJECTIVE

The present study investigated the effects of clerkship sequence and length on performance on the National Board of Medical Examiner’s subject examination in internal medicine.

PARTICIPANTS

The study sample included 16,091 students from 67 US Liaison Committee on Medical Education (LCME)-accredited medical schools who graduated in 2012 or 2013.

MAIN MEASURES

Student-level measures included first-attempt internal medicine subject examination scores, first-attempt USMLE Step 1 scores, and five dichotomous variables capturing whether or not students completed rotations in family medicine, ob/gyn, pediatrics, psychiatry, and surgery prior to taking the internal medicine rotation. School-level measures included clerkship length and average Step 1 score.

DESIGN

Multilevel models with students nested in schools were estimated with internal medicine subject examination scores as the dependent measure. Step 1 scores and the five dichotomous variables were treated as student-level predictors. Internal medicine clerkship length and average Step 1 score were used to predict school-to-school variation in average internal medicine subject examination scores.

KEY RESULTS

Completion of rotations in surgery, pediatrics and family medicine prior to taking the internal medicine examination significantly improved scores, with the largest benefit observed for surgery (coefficient = 1.58 points; p value < 0.01); completion of rotations in ob/gyn and psychiatry were unrelated to internal medicine subject examination performance. At the school level, longer internal medicine clerkships were associated with higher scores on the internal medicine examination (coefficient = 0.23 points/week; p value < 0.01).

CONCLUSIONS

The order in which students complete clinical clerkships and the length of the internal medicine clerkship are associated with their internal medicine subject examination scores. Findings may have implications for curriculum re-design.KEY WORDS: clinical education, internal medicine clerkship performance, clerkship sequence, clerkship length, NBME subject examinations     

The Relationship Between Food Insecurity and Depression,Diabetes Distress and Medication Adherence Among Low-Income Patients with Poorly-Controlled Diabetes

BACKGROUND

Food insecurity— lack of dependable access to adequate food—may play a role in poor diabetes control.

OBJECTIVE

We aimed to determine the relationship between food security status and depression, diabetes distress, medication adherence and glycemic control.

DESIGN

Secondary analysis of baseline data from Peer Support for Achieving Independence in Diabetes, a randomized controlled trial that enrolled patients from November 2011 to October 2013.

PARTICIPANTS

Participants had poorly controlled type 2 diabetes (A1c ≥ 8.0 % on eligibility screen), household income < 250 % of the federal poverty level, were 30–70 years old, and were recruited from a large public hospital, a VA medical center and a community-health center in King County, Washington.

MAIN MEASURES

We measured food insecurity determined by the Department of Agriculture’s 6-Item Food Security Module. Depression, diabetes distress and medication adherence measured by PHQ-8, Diabetes Distress Scale and Morisky Medication Adherence Scale, respectively. Diet was assessed through Summary of Diabetes Self-Care Activities and Starting the Conversation tool. Incidence of hypoglycemic episodes was by patient report. Glycemic control was assessed with glycosylated hemoglobin (A1c) values from fingerstick blood sample.

KEY RESULTS

The prevalence of food insecurity was 47.4 %. Chi-square tests revealed participants with food insecurity were more likely to be depressed (40.7 % vs. 15.4 %, p < 0.001), report diabetes distress (55.2 % vs. 33.8 %, p < 0.001) and have low medication adherence (52.9 % vs. 37.2 %, p = 0.02). Based on linear regression modeling, those with food insecurity had significantly higher mean A1c levels (β = 0.51; p = 0.02) after adjusting for sex, age, race/ethnicity, language, education, marital status, BMI, insulin use, depression, diabetes distress and low medication adherence.

CONCLUSIONS

Almost half of participants had food insecurity. Food insecurity was associated with depression, diabetes distress, low medication adherence and worse glycemic control. Even with adjustment, people with food insecurity had higher mean A1c levels than their food-secure counterparts, suggesting there may be other mediating factors, such as diet, that explain the relationship between food security status and diabetes control.KEY WORDS: food insecurity, diabetes, glycemic control     

Medical Students’ Views and Knowledge of the Affordable Care Act: A Survey of Eight U.S. Medical Schools

BACKGROUND

It is not known whether medical students support the Affordable Care Act (ACA) or possess the knowledge or will to engage in its implementation as part of their professional obligations.

OBJECTIVE

To characterize medical students’ views and knowledge of the ACA and to assess correlates of these views.

DESIGN

Cross-sectional email survey.

PARTICIPANTS

All 5,340 medical students enrolled at eight geographically diverse U.S. medical schools (overall response rate 52 % [2,761/5,340]).

MAIN MEASURES

Level of agreement with four questions regarding views of the ACA and responses to nine knowledge-based questions.

KEY RESULTS

The majority of respondents indicated an understanding of (75.3 %) and support for (62.8 %) the ACA and a professional obligation to assist with its implementation (56.1 %). The mean knowledge score from nine knowledge-based questions was 6.9 ± 1.3. Students anticipating a surgical specialty or procedural specialty compared to those anticipating a medical specialty were less likely to support the legislation (OR = 0.6 [0.4–0.7], OR = 0.4 [0.3–0.6], respectively), less likely to indicate a professional obligation to implement the ACA (OR = 0.7 [0.6–0.9], OR = 0.7 [0.5–0.96], respectively), and more likely to have negative expectations (OR = 1.9 [1.5–2.6], OR = 2.3 [1.6–3.5], respectively). Moderates, liberals, and those with an above-average knowledge score were more likely to indicate support for the ACA (OR = 5.7 [4.1–7.9], OR = 35.1 [25.4–48.5], OR = 1.7 [1.4–2.1], respectively) and a professional obligation toward its implementation (OR = 1.9 [1.4–2.5], OR = 4.7 [3.6–6.0], OR = 1.2 [1.02–1.5], respectively).

CONCLUSIONS

The majority of students in our sample support the ACA. Support was highest among students who anticipate a medical specialty, self-identify as political moderates or liberals, and have an above-average knowledge score. Support of the ACA by future physicians suggests that they are willing to engage with health care reform measures that increase access to care.KEY WORDS: Medical students, Health care reform, Affordable Care Act, Survey     

Medical School Experiences Associated with Change in Implicit Racial Bias Among 3547 Students: A Medical Student CHANGES Study Report

BACKGROUND

Physician implicit (unconscious, automatic) bias has been shown to contribute to racial disparities in medical care. The impact of medical education on implicit racial bias is unknown.

OBJECTIVE

To examine the association between change in student implicit racial bias towards African Americans and student reports on their experiences with 1) formal curricula related to disparities in health and health care, cultural competence, and/or minority health; 2) informal curricula including racial climate and role model behavior; and 3) the amount and favorability of interracial contact during school.

DESIGN

Prospective observational study involving Web-based questionnaires administered during first (2010) and last (2014) semesters of medical school.

PARTICIPANTS

A total of 3547 students from a stratified random sample of 49 U.S. medical schools.

MAIN OUTCOME(S) AND MEASURE(S)

Change in implicit racial attitudes as assessed by the Black-White Implicit Association Test administered during the first semester and again during the last semester of medical school.

KEY RESULTS

In multivariable modeling, having completed the Black-White Implicit Association Test during medical school remained a statistically significant predictor of decreased implicit racial bias (−5.34, p ≤ 0.001: mixed effects regression with random intercept across schools). Students'' self-assessed skills regarding providing care to African American patients had a borderline association with decreased implicit racial bias (−2.18, p = 0.056). Having heard negative comments from attending physicians or residents about African American patients (3.17, p = 0.026) and having had unfavorable vs. very favorable contact with African American physicians (18.79, p = 0.003) were statistically significant predictors of increased implicit racial bias.

CONCLUSIONS

Medical school experiences in all three domains were independently associated with change in student implicit racial attitudes. These findings are notable given that even small differences in implicit racial attitudes have been shown to affect behavior and that implicit attitudes are developed over a long period of repeated exposure and are difficult to change.KEY WORDS: disparities, medical education, implicit racial bias, physician–patient relations, attitude of health personnel     

Potential Impact of Incorporating a Patient-Selected Support Person into mHealth for Depression

Background

Although telephone care management improves depression outcomes, its implementation as a standalone strategy is often not feasible in resource-constrained settings. Moreover, little research has examined the potential role of self-management support from patients’ trusted confidants.

Objective

To investigate the potential benefits of integrating a patient-selected support person into automated mobile health (mHealth) for depression.

Design

Patient preference trial.

Participants

Depressed primary care patients who were at risk for antidepressant nonadherence (i.e., Morisky Medication Adherence Scale total score > 1).

Intervention

Patients received weekly interactive voice response (IVR) telephone calls for depression that included self-management guidance. They could opt to designate a lay support person from outside their home to receive guidance on supporting their self-management. Patients’ clinicians were automatically notified of urgent patient issues.

Main Measures

Each week over a period of 6 months, we used IVR calls to monitor depression with the Patient Health Questionnaire-9 (PHQ-9; with total < 5 classified as remission), adherence (single item reflecting perfect adherence over the past week), and functional impairment (any bed days due to mental health).

Key Results

Of 221 at-risk patients, 61% participated with a support person. Analyses were adjusted for race, medical comorbidity, and baseline levels of symptom severity and adherence. Significant interaction effects indicated that during the initial phase of the program, only patients who participated with a support person improved significantly in their likelihood of either adhering to antidepressant medication (AOR = 1.31, 95% CI: 1.16–1.47, p < 0.001) or achieving remission of depression symptoms (AOR = 1.24, 95% CI: 1.14–1.34, p < 0.001). These benefits were maintained throughout the 6-month observation period.

Conclusions

Incorporating the “human factor” of a patient-selected support person into automated mHealth for depression self-management may yield sustained improvements in antidepressant adherence and depression symptom remission. However, this needs to be confirmed in a subsequent randomized controlled trial.KEY WORDS: depression, mHealth, self-management, caregiving, social support     

A Break-Even Analysis for Dementia Care Collaboration: Partners in Dementia Care

Background

Dementia is a costly disease. People with dementia, their families, and their friends are affected on personal, emotional, and financial levels. Prior work has shown that the “Partners in Dementia Care” (PDC) intervention addresses unmet needs and improves psychosocial outcomes and satisfaction with care.

Objective

We examined whether PDC reduced direct Veterans Health Administration (VHA) health care costs compared with usual care.

Design

This study was a cost analysis of the PDC intervention in a 30-month trial involving five VHA medical centers.

Participants

Study subjects were veterans (N = 434) 50 years of age and older with dementia and their caregivers at two intervention (N = 269) and three comparison sites (N = 165).

Interventions

PDC is a telephone-based care coordination and support service for veterans with dementia and their caregivers, delivered through partnerships between VHA medical centers and local Alzheimer’s Association chapters.

Main Measures

We tested for differences in total VHA health care costs, including hospital, emergency department, nursing home, outpatient, and pharmacy costs, as well as program costs for intervention participants. Covariates included caregiver reports of veterans’ cognitive impairment, behavior problems, and personal care dependencies. We used linear mixed model regression to model change in log total cost post-baseline over a 1-year follow-up period.

Key Results

Intervention participants showed higher VHA costs than usual-care participants both before and after the intervention but did not differ significantly regarding change in log costs from pre- to post-baseline periods. Pre-baseline log cost (p ≤ 0.001), baseline cognitive impairment (p ≤ 0.05), number of personal care dependencies (p ≤ 0.01), and VA service priority (p ≤ 0.01) all predicted change in log total cost.

Conclusions

These analyses show that PDC meets veterans’ needs without significantly increasing VHA health care costs. PDC addresses the priority area of care coordination in the National Plan to Address Alzheimer’s Disease, offering a low-cost, structured, protocol-driven, evidence-based method for effectively delivering care coordination.KEY WORDS: costs and cost analysis, dementia, veterans     

Time to Loosen the Apron Strings: Cohort-based Evaluation of a Learner-driven Remediation Model at One Medical School

BACKGROUND

Remediation in the era of competency-based assessment demands a model that empowers students to improve performance.

AIM

To examine a remediation model where students, rather than faculty, develop remedial plans to improve performance.

SETTING/PARTICIPANTS

Private medical school, 177 medical students.

PROGRAM DESCRIPTION

A promotion committee uses student-generated portfolios and faculty referrals to identify struggling students, and has them develop formal remediation plans with personal reflections, improvement strategies, and performance evidence. Students submit reports to document progress until formally released from remediation by the promotion committee.

PROGRAM EVALUATION

Participants included 177 students from six classes (2009–2014). Twenty-six were placed in remediation, with more referrals occurring during Years 1 or 2 (n = 20, 76 %). Unprofessional behavior represented the most common reason for referral in Years 3–5. Remedial students did not differ from classmates (n = 151) on baseline characteristics (Age, Gender, US citizenship, MCAT) or willingness to recommend their medical school to future students (p < 0.05). Two remedial students did not graduate and three did not pass USLME licensure exams on first attempt. Most remedial students (92 %) generated appropriate plans to address performance deficits.

DISCUSSION

Students can successfully design remedial interventions. This learner-driven remediation model promotes greater autonomy and reinforces self-regulated learning.

Asking the Patient About Patient-Centered Medical Homes: A Qualitative Analysis

Background

What patients perceive and experience within a patient-centered medical home (PCMH) is an understudied area, and to date, the patient perspective has not been an integral component of existing PCMH measurement standards. However, upcoming guidelines necessitate the use of patient-reported experiences and satisfaction in evaluations of practice and provider performance.

Objective

To characterize patients’ experiences with care after PCMH adoption and their understanding and perceptions of the PCMH model and its key components, and to compare responses by degree of practice-level PCMH adoption and patient race/ethnicity.

Design

Qualitative study.

Participants

Adult patients with diabetes and/or hypertension (n = 48).

Approach

We surveyed and ranked all PCMH adult primary care practices affiliated with one academic medical center with at least three providers (n = 23), using an instrument quantifying the degree of PCMH adoption. We purposively sampled minority and non-minority patients from the four highest-ranked and four lowest-ranked PCMH-adopting practices to determine whether responses varied by degree of PCMH adoption or patient race/ethnicity. We conducted semi-structured telephone interviews with patients about their experiences with care and their perceptions and understanding of key PCMH domains. Interviews were recorded, transcribed, and imported into NVivo 10 for coding and analysis, using a modified grounded theory approach.

Key Results

We found that patients uniformly lacked awareness of the PCMH concept, and the vast majority perceived no PCMH-related structural changes, regardless of the degree of practice-reported PCMH adoption or the patient''s race/ethnicity. Despite this lack of awareness, patients overwhelmingly reported positive relationships with their provider and positive overall experiences.

Conclusions

As we continue to redesign primary care delivery with an emphasis on patient experience measures as performance metrics, we need to better understand what, if any, aspects of practice structure relate to patient experience and satisfaction with care.KEY WORDS: Patient-centered care, Primary care redesign, Health care delivery, Health services research, Health policy     

Medical Student Perceptions of Cost-Conscious Care in an Internal Medicine Clerkship: A Thematic Analysis

Background

Although as much as 87 % of all healthcare spending is directed by physicians, studies have demonstrated that they lack knowledge about the costs of medical care. Similarly, learners have not traditionally received instruction on cost-conscious care.

Objective

To examine medical students'' perceptions of healthcare delivery as it relates to cost consciousness

Design

Retrospective qualitative analysis of medical student narratives

Participants

Third-year medical students during their inpatient internal medicine clerkship

Main Measures

Students completed a reflective exercise wherein they were asked to describe a scenario in which a patient experienced lack of attention to cost-conscious care, and were asked to identify solutions and barriers. We analyzed these reflections to learn more about students’ awareness and perceptions regarding the practice of cost-conscious care within our medical center.

Key Results

Eighty students submitted the assignment between July and December 2012. The most common problems identified included unnecessary tests and treatments (n = 69) and duplicative tests and treatments (n = 20.) With regards to solutions, students described 82 scenarios, with 125 potential solutions identified. Students most commonly used discussion with the team (speak up, ask why) as the process they would use (n = 28) and most often wanted to focus lab testing (n = 38) as the intervention. The most common barriers to high-value care included increased time and effort (n = 19), ingrained practices (n = 17), and defensive medicine or fear of missing something (n = 18.)

Conclusions

Even with minimal clinical experience, medical students were able to identify instances of lack of attention to cost-conscious care as well as potential solutions. Although students identified the hierarchy in healthcare teams as a potential barrier to improving high value care, most students stated they would feel comfortable engaging the team in discussion. Future efforts to empower learners at all levels to question value decisions and to develop and implement solutions may result in improved healthcare.     

Impact of vitamin D supplementation on adiposity in African-Americans

Background:

African-Americans have higher rates of obesity-associated chronic diseases. Serum 25-hydroxyvitamin D (25(OH)D) shows an inverse association with obesity status. We investigated whether vitamin D supplementation changes body mass index (BMI).

Subjects:

In total, 328 overweight African-Americans were enrolled over three consecutive winter periods (2007–2010) into a randomized, double-blind, placebo-controlled trial to receive cholecalciferol supplementation (0, 1000 international units (IU), 2000 IU or 4000 IU per day) for 3 months. Plasma concentrations of 25(OH)D and anthropometric measurements were done at baseline, 3 and 6 months.

Results:

At 3 months, vitamin D supplementation in three dose groups (1000 IU, 2000 IU or 4000 IU per day) did not cause any significant changes in BMI as compared with placebo group 3-month change in BMI per 1000 IU per day estimate (SE): 0.01 (0.039); P=0.78.

Conclusions:

In overweight African-Americans, short-term high-dose vitamin D supplementation did not alter BMI.     

Patients Report Better Satisfaction with Part-Time Primary Care Physicians,Despite Less Continuity of Care and Access

BACKGROUND

The growing number of primary care physicians (PCPs) reducing their clinical work hours has raised concerns about meeting the future demand for services and fulfilling the continuity and access mandates for patient-centered care. However, the patient’s experience of care with part-time physicians is relatively unknown, and may be mediated by continuity and access to care outcomes.

OBJECTIVE

We aimed to examine the relationships between a physicians’ clinical full-time equivalent (FTE), continuity of care, access to care, and patient satisfaction with the physician.

DESIGN

We used a multi-level structural equation estimation, with continuity and access modeled as mediators, for a cross-section in 2010.

PARTICIPANTS

The study included family medicine (n = 104) and internal medicine (n = 101) physicians in a multi-specialty group practice, along with their patient satisfaction survey responses (n = 12,688).

MAIN MEASURES

Physician level FTE, continuity of care received by patients, continuity of care provided by physician, and a Press Ganey patient satisfaction with the physician score, on a 0–100 % scale, were measured. Access to care was measured as days to the third next-available appointment.

KEY RESULTS

Physician FTE was directly associated with better continuity of care received (0.172 % per FTE, p < 0.001), better continuity of care provided (0.108 % per FTE, p < 0.001), and better access to care (−0.033 days per FTE, p < 0.01), but worse patient satisfaction scores (−0.080 % per FTE, p = 0.03). The continuity of care provided was a significant mediator (0.016 % per FTE, p < 0.01) of the relationship between FTE and patient satisfaction; but overall, reduced clinical work hours were associated with better patient satisfaction (−0.053 % per FTE, p = 0.03).

CONCLUSIONS

These results suggest that PCPs who choose to work fewer clinical hours may have worse continuity and access, but they may provide a better patient experience. Physician workforce planning should consider these care attributes when considering the role of part-time PCPs in practice redesign efforts and initiatives to meet the demand for primary care services.

The Association Between Sensemaking During Physician Team Rounds and Hospitalized Patients’ Outcomes

BACKGROUND

Sensemaking is the social act of assigning meaning to ambiguous events. It is recognized as a means to achieve high reliability. We sought to assess sensemaking in daily patient care through examining how inpatient teams round and discuss patients.

OBJECTIVE

Our purpose was to assess the association between inpatient physician team sensemaking and hospitalized patients’ outcomes, including length of stay (LOS), unnecessary length of stay (ULOS), and complication rates.

DESIGN

Eleven inpatient medicine teams’ daily rounds were observed for 2 to 4 weeks. Rounds were audiotaped, and field notes taken. Four patient discussions per team were assessed using a standardized Situation, Task, Intent, Concern, Calibrate (STICC) framework.

PARTICIPANTS

Inpatient physician teams at the teaching hospitals affiliated with the University of Texas Health Science Center at San Antonio participated in the study. Outcomes of patients admitted to the teams were included.

MAIN MEASURES

Sensemaking was assessed based on the order in which patients were seen, purposeful rounding, patient-driven rounding, and individual patient discussions. We assigned teams a score based on the number of STICC elements used in the four patient discussions sampled. The association between sensemaking and outcomes was assessed using Kruskal-Wallis sum rank and Dunn’s tests.

KEY RESULTS

Teams rounded in several different ways. Five teams rounded purposefully, and four based rounds on patient-driven needs. Purposeful and patient-driven rounds were significantly associated with lower complication rates. Varying the order in which patients were seen and purposefully rounding were significantly associated with lower LOS, and purposeful and patient-driven rounds associated with lower ULOS. Use of a greater number of STICC elements was associated with significantly lower LOS (4.6 vs. 5.7, p = 0.01), ULOS (0.3 vs. 0.6, p = 0.02), and complications (0.2 vs. 0.5, p = 0.0001).

CONCLUSIONS

Improving sensemaking may be a strategy for improving patient outcomes, fostering a shared understanding of a patient’s clinical trajectory, and enabling high reliability.KEY WORDS: complexity science, sensemaking, length of stay, complication rates, inpatient teams     

The ABCs of DKA: Development and Validation of a Computer-Based Simulator and Scoring System

Background

Clinical management of diabetic ketoacidosis (DKA) continues to be suboptimal; simulation-based training may bridge this gap and is particularly applicable to teaching DKA management skills given it enables learning of basic knowledge, as well as clinical reasoning and patient management skills.

Objectives

1) To develop, test, and refine a computer-based simulator of DKA management; 2) to collect validity evidence, according to National Standard’s validity framework; and 3) to judge whether the simulator scoring system is an appropriate measure of DKA management skills of undergraduate and postgraduate medical trainees.

Design

After developing the DKA simulator, we completed usability testing to optimize its functionality. We then conducted a preliminary validation of the scoring system for measuring trainees’ DKA management skills.

Participants

We recruited year 1 and year 3 medical students, year 2 postgraduate trainees, and endocrinologists (n = 75); each completed a simulator run, and we collected their simulator-computed scores.

Main Measures

We collected validity evidence related to content, internal structure, relations with other variables, and consequences.

Key Results

Our simulator consists of six cases highlighting DKA management priorities. Real-time progression of each case includes interactive order entry, laboratory and clinical data, and individualised feedback. Usability assessment identified issues with clarity of system status, user control, efficiency of use, and error prevention. Regarding validity evidence, Cronbach’s α was 0.795 for the seven subscales indicating favorable internal structure evidence. Participants’ scores showed a significant effect of training level (p < 0.001). Scores also correlated with the number of DKA patients they reported treating, weeks on Medicine rotation, and comfort with managing DKA. A score on the simulation exercise of 75 % had a sensitivity and specificity of 94.7 % and 51.8%, respectively, for delineating between expert staff physicians and trainees.

Conclusions

We demonstrate how a simulator and scoring system can be developed, tested, and refined to determine its quality for use as an assessment modality. Our evidence suggests that it can be used for formative assessment of trainees’ DKA management skills.KEY WORDS: medical education, assessment/evaluation, medical education, clinical skills training, medical education, computer/web-based training, medical education, instructional design, medical education, simulation     

Adherence to Metformin,Statins, and ACE/ARBs Within the Diabetes Health Plan (DHP)

Background

Reducing patient cost-sharing and engaging patients in disease management activities have been shown to increase uptake of evidence-based care.

Objective

To evaluate the effect of employer purchase of a disease-specific plan with reduced cost-sharing and disease management (the Diabetes Health Plan/DHP) on medication adherence among eligible employees and dependents.

Design

Employer-level “intent to treat” cohort study, including data from eligible employees and their dependents with diabetes, regardless of whether they were enrolled in the DHP.

Setting

Employers that contracted with a large national health plan administrator in 2009, 2010, and/or 2011.

Participants

Ten employers that purchased the DHP and 191 employers that did not (controls). Inverse probability weighting (IPW) estimation was used to adjust for inter-group differences.

Intervention

The DHP includes free or low-cost medications and physician visits. Enrollment strategies and specific benefit designs are determined by the employer and vary in practice. DHP participants are notified up front that they must engage in their own health care (e.g., receiving diabetes-related screening) in order to remain enrolled.

Main Outcome Measure

Mean employee adherence to metformin, statins, and ACE/ARBs at the employer level at one year post-DHP implementation, as measured by the proportion of days covered (PDC).

Results

Baseline adherence to the three medications was similar across DHP and control employers, ranging from 64 to 69 %. In the first year after DHP implementation, predicted employer-level adherence for metformin (+4.9 percentage points, p = 0.017), statins (+4.8, p = 0.019), and ACE/ARBs (+4.4, p = 0.02) was higher with DHP purchase.

Limitations

Non-randomized, observational study.

Conclusions

The Diabetes Health Plan, an innovative health plan that combines reduced cost-sharing and disease management with an up-front requirement of enrollee participation in his or her own health care, is associated with a modest improvement in medication adherence at 12 months.

The online version of this article (doi:10.1007/s11606-015-3284-8) contains supplementary material, which is available to authorized users.Type 2 diabetes is highly prevalent in the United States, and leads to reduced functional status and disabling complications for many patients. The total economic cost of diabetes in 2012 has been estimated at $245 billion, which is an increase of 41 % since 2007.¹ This cost includes $176 billion in direct medical care, as well as $69 billion in decreased productivity such as absenteeism, reduced work performance, and reduced labor force participation.¹ Importantly, greater adherence to diabetes-related medications has been shown to decrease hospitalizations and emergency department use and to reduce costs of care.^2–4 Given these issues, employers have a strong interest in trying alternative approaches to providing medical care for their employees with diabetes.The Diabetes Health Plan (DHP) is an example of a novel health benefit design that became available to public and private employers in 2009. The DHP is the first disease-specific health plan in the United States for patients with diabetes and pre-diabetes, and offers features such as reduced cost-sharing for medications and office visits and free or low-cost resources for disease management. The DHP was actuarially designed to provide an estimated annual out-of-pocket savings of $150–$500 per participant.⁵As some employers purchased the DHP, while other similar employers did not, there is a unique opportunity to conduct a rigorous evaluation of a real-world intervention. In the current study, we examined the impact of the DHP on adherence to three evidence-based medications covered by the DHP (metformin, statins, ACE/ARBs) over 12 months. We also examined adherence to two unrelated medications that were not covered by the DHP (thyroxine, montelukast) in order to test whether our findings were related to the DHP. We chose to conduct employer-level analyses in order to provide information to guide the critical decision faced by employers in terms of which health plans to offer to their employees. With the employer as the unit of analysis, we predicted the average medication adherence across all DHP-eligible employees and dependents with diabetes whose employers had purchased the DHP, regardless of whether these patients actually enrolled in the plan.
