Nurse-Led Behavioral Management of Diabetes and Hypertension in Community Practices: A Randomized Trial

Background

Several trials have demonstrated the efficacy of nurse telephone case management for diabetes (DM) and hypertension (HTN) in academic or vertically integrated systems. Little is known about the real-world potency of these interventions.

Objective

To assess the effectiveness of nurse behavioral management of DM and HTN in community practices among patients with both diseases.

Design

The study was designed as a patient-level randomized controlled trial.

Participants

Participants included adult patients with both type 2 DM and HTN who were receiving care at one of nine community fee-for-service practices. Subjects were required to have inadequately controlled DM (hemoglobin A1c [A1c] ≥ 7.5 %) but could have well-controlled HTN.

Interventions

All patients received a call from a nurse experienced in DM and HTN management once every two months over a period of two years, for a total of 12 calls. Intervention patients received tailored DM- and HTN- focused behavioral content; control patients received non-tailored, non-interactive information regarding health issues unrelated to DM and HTN (e.g., skin cancer prevention).

Main Outcomes and Measures

Systolic blood pressure (SBP) and A1c were co-primary outcomes, measured at 6, 12, and 24 months; 24 months was the primary time point.

Results

Three hundred seventy-seven subjects were enrolled; 193 were randomized to intervention, 184 to control. Subjects were 55 % female and 50 % white; the mean baseline A1c was 9.1 % (SD = 1 %) and mean SBP was 142 mmHg (SD = 20). Eighty-two percent of scheduled interviews were conducted; 69 % of intervention patients and 70 % of control patients reached the 24-month time point. Expressing model estimated differences as (intervention – control), at 24 months, intervention patients had similar A1c [diff = 0.1 %, 95 % CI (−0.3, 0.5), p = 0.51] and SBP [diff = −0.9 mmH g, 95% CI (−5.4, 3.5), p = 0.68] values compared to control patients. Likewise, DBP (diff = 0.4 mmHg, p = 0.76), weight (diff = 0.3 kg, p = 0.80), and physical activity levels (diff = 153 MET-min/week, p = 0.41) were similar between control and intervention patients. Results were also similar at the 6- and 12-month time points.

Conclusions

In nine community fee-for-service practices, telephonic nurse case management did not lead to improvement in A1c or SBP. Gains seen in telephonic behavioral self-management interventions in optimal settings may not translate to the wider range of primary care settings.KEY WORDS: Diabetes, Hypertension, Implementation     

The Effectiveness of a Physician-Only and Physician–Patient Intervention on Colorectal Cancer Screening Discussions Between Providers and African American and Latino Patients

BACKGROUND

Physician recommendation of colorectal cancer (CRC) screening is a critical facilitator of screening completion. Providing patients a choice of screening options may increase CRC screening completion, particularly among racial and ethnic minorities.

OBJECTIVE

Our purpose was to assess the effectiveness of physician-only and physician–patient interventions on increasing rates of CRC screening discussions as compared to usual care.

DESIGN

This study was quasi-experimental. Clinics were allocated to intervention or usual care; patients in intervention clinics were randomized to receipt of patient intervention.

PARTICIPANTS

Patients aged 50 to 75 years, due for CRC screening, receiving care at either a federally qualified health care center or an academic health center participated in the study.

INTERVENTION

Intervention physicians received continuous quality improvement and communication skills training. Intervention patients watched an educational video immediately before their appointment.

MAIN MEASURES

Rates of patient-reported 1) CRC screening discussions, and 2) discussions of more than one screening test.

KEY RESULTS

The physician–patient intervention (n = 167) resulted in higher rates of CRC screening discussions compared to both physician-only intervention (n = 183; 61.1 % vs.50.3 %, p = 0.008) and usual care (n = 153; 61.1 % vs. 34.0 % p = 0.03). More discussions of specific CRC screening tests and discussions of more than one test occurred in the intervention arms than in usual care (44.6 % vs. 22.9 %,p = 0.03) and (5.1 % vs. 2.0 %, p = 0.036), respectively, but discussion of more than one test was uncommon. Across all arms, 143 patients (28.4 %) reported discussion of colonoscopy only; 21 (4.2 %) reported discussion of both colonoscopy and stool tests.

CONCLUSIONS

Compared to usual care and a physician-only intervention, a physician–patient intervention increased rates of CRC screening discussions, yet discussions overwhelmingly focused solely on colonoscopy. In underserved patient populations where access to colonoscopy may be limited, interventions encouraging discussions of both stool tests and colonoscopy may be needed.KEY WORDS: colorectal cancer screening, health literacy, randomized trial, physician communication of preventive care     

Survival and Racial Differences of Non-Small Cell Lung Cancer in the United States Military

BACKGROUND

Lung cancer is the leading cause of cancer-related death in the United States (US) Military and worldwide, with non-small cell lung cancer (NSCLC) accounting for 87 % of cases.

OBJECTIVES

Using a US military cohort who receives equal and open access to healthcare, we sought to examine demographic, clinical features and outcomes with NSCLC.

DESIGN AND PARTICIPANTS

We conducted a retrospective cohort analysis of 4,751 patients, aged ≥ 18 years and diagnosed with a first primary NSCLC between 1 January 2003 and 31 December 2013 in the US Department of Defense (DoD) cancer registry.

MAIN MEASURES

Differences by patient and disease characteristics were compared using Chi-square and t-test. Kaplan Meier curves and Cox proportional hazards regression assessed overall survival.

RESULTS

The mean age at diagnosis was 66 years, 64 % were male, 72 % were Caucasian, 41 % were diagnosed at early stage, 77 % received treatment and 82 % had a history of tobacco use. Mean age at diagnosis was highest among Caucasians (67 years) and lowest among African Americans (AA; 62 years). Asian/Pacific Islanders (PI) were more likely to be female (p < 0.0001), have adenocarcinoma histology (p = 0.0003) and less likely to have a history of tobacco use (p < 0.0001) compared to other racial/ethnic groups. In multivariable survival analysis, older age, male gender, increasing stage, not receiving treatment, and tobacco history were associated with higher mortality risk. Untreated patients exhibited a 39 % higher mortality risk compared to treated patients (HR = 1.39; 95%CI = 1.23–1.57). Compared to Caucasian patients, Asian/PIs demonstrated a 20 % lower risk of death (HR = 0.80; 95%CI = 0.66–0.96). There was no difference in mortality risk between AAs and Hispanics compared to Caucasians.

CONCLUSION

The lack of significant outcome disparity between AAs and Caucasians and the earlier stage at diagnosis than usually seen in civilian populations suggest that equal access to healthcare may play a role in early detection and survival.KEY WORDS: military, lung cancer, survival outcomes     

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     

Accuracy of Race,Ethnicity, and Language Preference in an Electronic Health Record

BACKGROUND

Collection of data on race, ethnicity, and language preference is required as part of the “meaningful use” of electronic health records (EHRs). These data serve as a foundation for interventions to reduce health disparities.

OBJECTIVE

Our aim was to compare the accuracy of EHR-recorded data on race, ethnicity, and language preference to that reported directly by patients.

DESIGN/SUBJECTS/MAIN MEASURES

Data collected as part of a tobacco cessation intervention for minority and low-income smokers across a network of 13 primary care clinics (n = 569).

KEY RESULTS

Patients were more likely to self-report Hispanic ethnicity (19.6 % vs. 16.6 %, p < 0.001) and African American race (27.0 % vs. 20.4 %, p < 0.001) than was reported in the EHR. Conversely, patients were less likely to complete the survey in Spanish than the language preference noted in the EHR suggested (5.1 % vs. 6.3 %, p < 0.001). Thirty percent of whites self-reported identification with at least one other racial or ethnic group, as did 37.0 % of Hispanics, and 41.0 % of African Americans. Over one-third of EHR-documented Spanish speakers elected to take the survey in English. One-fifth of individuals who took the survey in Spanish were recorded in the EHR as English-speaking.

CONCLUSION

We demonstrate important inaccuracies and the need for better processes to document race/ ethnicity and language preference in EHRs.KEY WORDS: disparities, race, ethnicity, health information technology     

Acute Care Utilization by Patients After Graduation of Their Resident Primary Care Physicians

BACKGROUND

The disruption in provider continuity caused by medical resident graduation may result in adverse patient outcomes.

OBJECTIVE

Our aim was to investigate whether resident graduation was associated with increased acute care utilization by residents’ primary care patients.

DESIGN AND PARTICIPANTS

This was a retrospective cohort study of patients cared for by junior and senior residents finishing the academic year in 2010, 2011 and 2012.

MAIN MEASURES

We compared rates of clinic visits, emergency department (ED) visits, and hospitalizations between transitioning patients whose residents were graduating and non-transitioning patients whose residents were not graduating.

KEY RESULTS

Our study population comprised 90 residents, 4018 unique patients, and 5988 resident–patient dyads that transitioned (n = 3136) or did not transition (n = 2852). For transitioning patients, the clinic visit rate per 100 patients in the 4 months before and after graduation was 129 and 102, respectively; for non-transitioning patients, the clinic visit rate was 119 and 94, respectively (difference-in-differences, +2 per 100 patients; p = 0.12). For transitioning patients, the ED visit rate per 100 patients before and after graduation was 29 and 26, respectively; for non-transitioning patients, the ED visit rate was 28 and 25, respectively (difference-in-differences, 0; p = 0.49). For transitioning patients, the hospitalization rate per 100 patients before and after graduation was 14 and 13, respectively; for non-transitioning patients, the hospitalization rate was 15 and 12, respectively (difference-in-differences, −2; p = 0.20). In multivariable modeling there was no increased risk for transitioning patients for clinic visits (adjusted rate ratio [aRR], 1.03; 95 % confidence interval [CI], 0.97 to 1.10), ED visits (aRR, 1.05; 95 % CI, 0.92 to 1.20), or hospitalizations (aRR, 1.04; 95 % CI, 0.83 to 1.31).

CONCLUSIONS

Acute care utilization by residents’ patients did not increase or decrease after graduation. Acute care utilization was high before and after graduation. Interventions to decrease the need for acute care should be employed throughout the year.KEY WORDS: continuity of care, care transitions, medical education-systems based practice, medical education-graduate, ambulatory care, utilization     

The Effect of a Care Transition Intervention on the Patient Experience of Older Multi-Lingual Adults in the Safety Net: Results of a Randomized Controlled Trial

Background

The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) and Care Transitions Measure (CTM-3) scores are patient experience measures used to determine hospital value-based purchasing reimbursement. Interventions to improve 30-day readmissions have met with mixed results, but less is known about their potential to improve the patient experience among older ethnically and linguistically diverse adults receiving care at safety-net hospitals. In this study, we assessed the effect of a nurse-led hospital-based care transition intervention on discharge-related patient experience in an older multilingual population of adults hospitalized at a safety-net hospital.

Methods

We randomized 700 inpatients aged 55 and older at an academic urban safety-net hospital. In addition to usual care, intervention participants received inpatient visits by a language-concordant study nurse and post-discharge phone calls from a language-concordant nurse practitioner to reinforce the care plan and to address acute complaints. We measured HCAHPS nursing, medication, and discharge communication domain scores and CTM-3 scores at 30 days after hospital discharge.

Results

Of 685 participants who survived to 30 days, 90 % (n = 616) completed follow-up interviews. The mean age was 66.2 years; over half (54.2 %) of the participants had cognitive impairment, and 33.8 % had moderate to severe depression. The majority (62.1 %) of interviews were conducted in English; 23.3 % were conducted in Chinese and 14.6 % in Spanish. Study nurses spent an average of 157 min with intervention participants. Between intervention and usual care participants, CTM-3 scores (80.5 % vs 78.5 %; p = 0.18) and HCAHPS discharge communication domain scores (74.8 % vs 68.7 %; p = 0.11) did not differ, nor did HCAHPS scores in medication (44.5 % vs 53.1 %; p = 0.13) and nursing domains (67.9 % vs 64.9 %; p = 0.43). When stratified by language, no significant differences were seen.

Conclusion

An inpatient standalone transition-of-care intervention did not improve patient discharge experience. Older multi-lingual and cognitively impaired populations may require higher-intensity interventions post-hospitalization to improve discharge experience outcomes.KEY WORDS: Transitions of care, Patient experience, Randomized controlled trial, Vulnerable populations     

Hospital Strategy Uptake and Reductions in Unplanned Readmission Rates for Patients with Heart Failure: A Prospective Study

BACKGROUND

Despite recent reductions in national unplanned readmission rates, we have relatively little understanding of which hospital strategies are most associated with changes in risk-standardized readmission rates (RSRR).

OBJECTIVE

We examined associations between the change in hospital 30-day RSRR for patients with heart failure and the uptake of strategies over 12–18 months in a national sample of hospitals.

DESIGN

We conducted a prospective study of hospitals using a Web-based survey at baseline (November 2010–May 2011, n = 599, 91.0 % response rate) and 12–18 months later (November 2011–October 2012, n = 501, 83.6 % response rate), with RSRR measured at the same time points. The final analytic sample included 478 hospitals.

PARTICIPANTS

The study included hospitals participating in the Hospital-to-Home (H2H) and State Action on Avoidable Rehospitalizations (STAAR) initiatives.

MAIN MEASURES

We examined associations between change in hospital 30-day RSRR for patients with heart failure and the uptake of strategies previously demonstrated to have increased between baseline and follow-up, using unadjusted and adjusted linear regression.

KEY RESULTS

The average number of strategies taken up from baseline to follow-up was 1.6 (SE = 0.06); approximately one-quarter (25.3 %) of hospitals took up at least three new strategies. Hospitals that adopted the strategy of routinely discharging patients with a follow-up appointment already scheduled experienced significant reductions in RSRR (reduction of 0.63 percentage point, p value < 0.05). Hospitals that took up three or more strategies had significantly greater reductions in RSRR compared to hospitals that took up only zero to two strategies (reduction of 1.29 versus 0.57 percentage point, p value < 0.05). Among the 117 hospitals that took up three or more strategies, 93 unique combinations of strategies were used.

CONCLUSIONS

Although most individual strategies were not associated with RSRR reduction, hospitals that took up any three or more strategies showed significantly greater reduction in RSRR compared to hospitals that took up fewer than three strategies.

Effectiveness of a Physical Activity and Weight Loss Intervention for Middle-Aged Women: Healthy Bodies,Healthy Hearts Randomized Trial

BACKGROUND

Physical inactivity is a significant risk factor for cardiovascular disease and remains highly prevalent in middle-aged women.

OBJECTIVE

We hypothesized that an interventionist-led (IL), primary-care–based physical activity (PA) and weight loss intervention would increase PA levels and decrease weight to a greater degree than a self-guided (SG) program.

DESIGN

We conducted a randomized trial.

PARTICIPANTS

Ninety-nine inactive women aged 45–65 years and with BMI ≥ 25 kg/m² were recruited from three primary care clinics.

INTERVENTIONS

The interventionist-led (IL) group (n = 49) had 12 weekly sessions of 30 min discussions with 30 min of moderate-intensity PA. The self-guided (SG) group (n = 50) received a manual for independent use.

MAIN MEASURES

Assessments were conducted at 0, 3, and 12 months; PA and weight were primary outcomes. Weight was measured with a standardized protocol. Leisure PA levels were assessed using the Modifiable Activity Questionnaire. Differences in changes by group were analyzed with a t-test or Wilcoxon rank-sum test. Mixed models were used to analyze differences in changes of outcomes by group, using an intention-to-treat principle.

KEY RESULTS

Data from 98 women were available for analysis. At baseline, mean (SD) age was 53.9 (5.4) years and 37 % were black. Mean weight was 92.3 (17.7) kg and mean BMI was 34.7 (5.9) kg/m². Median PA level was 2.8 metabolic equivalent hours per week (MET-hour/week) (IQR 0.0, 12.0). At 3 months, IL women had a significantly greater increase in PA levels (7.5 vs. 1.9 MET-hour/week; p = 0.02) than SG women; there was no significant difference in weight change. At 12 months, the difference between groups was no longer significant (4.7 vs. 0.7 MET-hour/week; p = 0.38). Mixed model analysis showed a significant (p = 0.048) difference in PA change between groups at 3 months only.

CONCLUSIONS

The IL intervention was successful in increasing the physical activity levels of obese, inactive middle-aged women in the short-term. No significant changes in weight were observed.

A Randomized Controlled Trial of a CPR and Intubation Video Decision Support Tool for Hospitalized Patients

BACKGROUND

Decisions about cardiopulmonary resuscitation (CPR) and intubation are a core part of advance care planning, particularly for seriously ill hospitalized patients. However, these discussions are often avoided.

OBJECTIVES

We aimed to examine the impact of a video decision tool for CPR and intubation on patients’ choices, knowledge, medical orders, and discussions with providers.

DESIGN

This was a prospective randomized trial conducted between 9 March 2011 and 1 June 2013 on the internal medicine services at two hospitals in Boston.

PARTICIPANTS

One hundred and fifty seriously ill hospitalized patients over the age of 60 with an advanced illness and a prognosis of 1 year or less were included. Mean age was 76 and 51 % were women.

INTERVENTION

Three-minute video describing CPR and intubation plus verbal communication of participants’ preferences to their physicians (intervention) (N = 75) or control arm (usual care) (N = 75).

MAIN MEASURES

The primary outcome was participants’ preferences for CPR and intubation (immediately after viewing the video in the intervention arm). Secondary outcomes included: orders to withhold CPR/intubation, documented discussions with providers during hospitalization, and participants’ knowledge of CPR/ intubation (five-item test, range 0–5, higher scores indicate greater knowledge).

RESULTS

Intervention participants (vs. controls) were more likely not to want CPR (64 % vs. 32 %, p <0.0001) and intubation (72 % vs. 43 %, p < 0.0001). Intervention participants (vs. controls) were also more likely to have orders to withhold CPR (57 % vs. 19 %, p < 0.0001) and intubation (64 % vs.19 %, p < 0.0001) by hospital discharge, documented discussions about their preferences (81 % vs. 43 %, p < 0.0001), and higher mean knowledge scores (4.11 vs. 2.45; p < 0.0001).

CONCLUSIONS

Seriously ill patients who viewed a video about CPR and intubation were more likely not to want these treatments, be better informed about their options, have orders to forgo CPR/ intubation, and discuss preferences with providers.Trial registration: Clinicaltrials.gov {"type":"clinical-trial","attrs":{"text":"NCT01325519","term_id":"NCT01325519"}}NCT01325519Registry Name: A prospective randomized trial using video images in advance care planning in seriously ill hospitalized patients.     

Reducing PSA-Based Prostate Cancer Screening in Men Aged?75?Years and Older with the Use of Highly Specific Computerized Clinical Decision Support

INTRODUCTION

In 2012, the Veterans Health Administration (VHA) implemented guidelines seeking to reduce PSA-based screening for prostate cancer in men aged 75 years and older.

OBJECTIVES

To reduce the use of inappropriate PSA-based prostate cancer screening among men aged 75 and over.

SETTING

The Veterans Affairs Greater Los Angeles Healthcare System (VA GLA)

PROGRAM DESCRIPTION

We developed a highly specific computerized clinical decision support (CCDS) alert to remind providers, at the moment of PSA screening order entry, of the current guidelines and institutional policy. We implemented the tool in a prospective interrupted time series study design over 15 months, and compared the trends in monthly PSA screening rate at baseline to the CCDS on and off periods of the intervention.

RESULTS

A total of 30,150 men were at risk, or eligible, for screening, and 2,001 men were screened. The mean monthly screening rate during the 15-month baseline period was 8.3 %, and during the 15-month intervention period, was 4.6 %. The screening rate declined by 38 % during the baseline period and by 40 % and 30 %, respectively, during the two periods when the CCDS tool was turned on. The screening rate ratios for the baseline and two periods when the CCDS tool was on were 0.97, 0.78, and 0.90, respectively, with a significant difference between baseline and the first CCDS-on period (p < 0.0001), and a trend toward a difference between baseline and the second CCDS-on period (p = 0.056).

CONCLUSION

Implementation of a highly specific CCDS tool alone significantly reduced inappropriate PSA screening in men aged 75 years and older in a reproducible fashion. With this simple intervention, evidence-based guidelines were brought to bear at the point of care, precisely for the patients and providers for whom they were most helpful, resulting in more appropriate use of medical resources.KEY WORDS: electronic health records, physician decision support, cancer screening, applied informatics, implementation research, quality improvement     

Increased Cardiovascular Disease,Resource Use,and Costs Before the Clinical Diagnosis of Diabetes in Veterans in the Southeastern U.S.

Importance

Screening for diabetes might be more widespread if adverse associations with cardiovascular disease (CVD), resource use, and costs were known to occur earlier than conventional clinical diagnosis.

Objective

The purpose of this study was to determine whether adverse effects associated with diabetes begin prior to clinical diagnosis.

Design

Veterans with diabetes were matched 1:2 with controls by follow-up, age, race/ethnicity, gender, and VA facility. CVD was obtained from ICD-9 codes, and resource use and costs from VA datasets.

Setting

VA facilities in SC, GA, and AL.

Participants

Patients with and without diagnosed diabetes.

Main Outcome Measures

Diagnosed CVD, resource use, and costs.

Results

In this study, the 2,062 diabetic patients and 4,124 controls were 63 years old on average, 99 % male, and 29 % black; BMI was 30.8 in diabetic patients vs. 27.8 in controls (p<0.001). CVD prevalence was higher and there were more outpatient visits in Year −4 before diagnosis through Year +4 after diagnosis among diabetic vs. control patients (all p<0.01); in Year −2, CVD prevalence was 31 % vs. 24 %, and outpatient visits were 22 vs. 19 per year, respectively. Total VA costs/year/veteran were higher in diabetic than control patients from Year −4 ($4,083 vs. $2,754) through Year +5 ($8,347 vs. $5,700) (p<0.003) for each, reflecting underlying increases in outpatient, inpatient, and pharmacy costs (p<0.05 for each). Regression analysis showed that diabetes contributed an average of $1,748/year to costs, independent of CVD (p<0.001).

Conclusions and Relevance

VA costs per veteran are higher—over $1,000/year before and $2,000/year after diagnosis of diabetes—due to underlying increases in outpatient, inpatient, and pharmacy costs, greater number of outpatient visits, and increased CVD. Moreover, adverse associations with veterans’ health and the VA healthcare system occur early in the natural history of the disease, several years before diabetes is diagnosed. Since adverse associations begin before diabetes is recognized, greater consideration should be given to systematic screening in order to permit earlier detection and initiation of preventive management. Keeping frequency of CVD and marginal costs in line with those of patients before diabetes is currently diagnosed has the potential to save up to $2 billion a year.

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.

Chronic Pain and DepressionAmong Primary Care Patients Treated with Buprenorphine

BACKGROUND

Pain and depression are each prevalent among opioid dependent patients receiving maintenance buprenorphine, but their interaction has not been studied in primary care patients.

OBJECTIVE

We set out to examine the relationship between chronic pain, depression, and ongoing substance use, among persons maintained on buprenorphine in primary care settings.

DESIGN

Between September 2012 and December 2013, we interviewed buprenorphine patients at three practice sites.

PARTICIPANTS

Opioid dependent persons at two private internal medicine offices and a federally qualified health center participated in the study.

MAIN MEASURES

Pain was measured in terms of chronicity, with chronic pain being defined as pain lasting at least 6 months; and in terms of severity, as measured by self-reported pain in the past week, measured on a 0–100 scale. We defined mild chronic pain as pain severity between 0 and 39 and lasting at least 6 months, and moderate/severe chronic pain as severity ≥ 40 and lasting at least 6 months. To assess depression, we used the Center for Epidemiologic Studies Depression (CESD) ten-item symptom scale and the two-item Patient Health Questionnaire (PHQ-2).

KEY RESULTS

Among 328 participants, 169 reported no chronic pain, 56 reported mild chronic pain, and 103 reported moderate/severe chronic pain. Participants with moderate/severe chronic pain commonly used non-opioid pain medications (56.3 %) and antidepressants (44.7 %), yet also used marijuana, alcohol, or cocaine (40.8 %) to help relieve pain. Mean CESD scores were 7.1 (±6.8), 8.3 (±6.0), and 13.6 (±7.6) in the no chronic, mild, and moderate/severe pain groups, respectively. Controlling for covariates, higher CESD scores were associated with a higher likelihood of moderate/severe chronic pain relative to both no chronic pain (OR = 1.09, p < 0.001) and mild chronic pain (OR = 1.06, p = 0.04).

CONCLUSION

Many buprenorphine patients are receiving over-the-counter or prescribed pain medications, as well as antidepressants, and yet continue to have significant and disabling pain and depressive symptoms. There is a clear need to address the pain–depression nexus in novel ways.KEY WORDS: buprenorphine, chronic pain, depression     

Variation in Inpatient Consultation Among Older Adults in the United States

BACKGROUND

Differences among hospitals in the use of inpatient consultation may contribute to variation in outcomes and costs for hospitalized patients, but basic epidemiologic data on consultations nationally are lacking.

OBJECTIVE

The purpose of the study was to identify physician, hospital, and geographic factors that explain variation in rates of inpatient consultation.

DESIGN

This was a retrospective observational study.

SETTING AND PARTICIPANTS

This work included 3,118,080 admissions of Medicare patients to 4,501 U.S. hospitals in 2009 and 2010.

MAIN MEASURES

The primary outcome measured was number of consultations conducted during the hospitalization, summarized at the hospital level as the number of consultations per 1,000 Medicare admissions, or “consultation density.”

KEY RESULTS

Consultations occurred 2.6 times per admission on average. Among non-critical access hospitals, use of consultation varied 3.6-fold across quintiles of hospitals (933 versus 3,390 consultations per 1,000 admissions, lowest versus highest quintiles, p < 0.001). Sicker patients received greater intensity of consultation (rate ratio [RR] 1.18, 95 % CI 1.17–1.18 for patients admitted to ICU; and RR 1.19, 95 % CI 1.18–1.20 for patients who died). However, even after controlling for patient-level factors, hospital characteristics also predicted differences in rates of consultation. For example, hospital size (large versus small, RR 1.31, 95 % CI 1.25–1.37), rural location (rural versus urban, RR 0.78, CI 95 % 0.76–0.80), ownership status (public versus not-for-profit, RR 0.94, 95 % CI 0.91–0.97), and geographic quadrant (Northeast versus West, RR 1.17, 95 % CI 1.12–1.21) all influenced the intensity of consultation use.

CONCLUSIONS

Hospitals exhibit marked variation in the number of consultations per admission in ways not fully explained by patient characteristics. Hospital “consultation density” may constitute an important focus for monitoring resource use for hospitals or health systems.

Reflecting on Diagnostic Errors: Taking a Second Look is Not Enough

BACKGROUND

An experimenter controlled form of reflection has been shown to improve the detection and correction of diagnostic errors in some situations; however, the benefits of participant-controlled reflection have not been assessed.

OBJECTIVE

The goal of the current study is to examine how experience and a self-directed decision to reflect affect the accuracy of revised diagnoses.

DESIGN

Medical residents diagnosed 16 medical cases (pass 1). Participants were then given the opportunity to reflect on each case and revise their diagnoses (pass 2).

PARTICIPANTS

Forty-seven medical Residents in post-graduate year (PGY) 1, 2 and 3 were recruited from Hamilton Health Care Centres.

MAIN MEASURES

Diagnoses were scored as 0 (incorrect), 1 (partially correct) and 2 (correct). Accuracies and response times in pass 1 were analyzed using an ANOVA with three factors—PGY, Decision to revise yes/no, and Case 1–16, averaged across residents. The extent to which additional reflection affected accuracy was examined by analyzing only those cases that were revised, using a repeated measures ANOVA, with pass 1 or 2 as a within subject factor, and PGY and Case or Resident as a between-subject factor.

KEY RESULTS

The mean score at pass 1 for each level was PGY1, 1.17 (SE 0.50); PGY2, 1.35 (SE 0.67) and PGY3, 1.27 (SE 0.94). While there was a trend for increased accuracy with level, this did not achieve significance. The number of residents at each level who revised at least one diagnosis was 12/19 PGY1 (63 %), 9/11 PGY2 (82 %) and 8/17 PGY3 (47 %). Only 8 % of diagnoses were revised resulting in a small but significant increase in scores from Pass 1 to 2, from 1.20/2 to 1.22 /2 (t = 2.15, p = 0.03).

CONCLUSIONS

Participants did engage in self-directed reflection for incorrect diagnoses; however, this strategy provided minimal benefits compared to knowing the correct answer. Education strategies should be directed at improving formal and experiential knowledge.

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     

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
