Disagreement between pharmacy claims and direct interview to identify patients with non-adherence to chronic cardiometabolic medications.

BACKGROUND: Accurate methods of identifying patients with suboptimal adherence to cardiometabolic medications are needed, and each approach has benefits and tradeoffs. METHODS: We used data from a large trial of patients with poorly controlled cardiometabolic disease and evidence of medication non-adherence measured using pharmacy claims data whose adherence was subsequently assessed during a telephone consultation with a clinical pharmacist. We then evaluated if the pharmacist assessment agreed with the non-adherence measured using claims. When pharmacist and claims assessments disagreed, we identified reasons why claims were insufficient and used multivariable modified Poisson regression to identify patient characteristics associated with disagreement. RESULTS: Of 1,069 patients identified as non-adherent using claims (proportion of days covered [PDC] <80%), 646 (60.4%) were confirmed as non-adherent on pharmacist interview. For the 423 patients (39.6%) where the interview disagreed with the claims, the most common reasons were paying cash or using an alternate insurance (36.6%), medication discontinuation or regimen change (32.8%), and recently becoming adherent (26.7%). Compared to patients whose claims and interview both showed non-adherence, patients whose interview disagreed with claims were less likely to miss outpatient office visits (RR:0.91, 95%CI:0.85-0.97) and more likely to have a baseline PDC above the median (RR:1.35, 95%CI:1.10-1.64). CONCLUSIONS: Among patients identified as non-adherent by claims, 39.6% were observed to be adherent when assessed during pharmacist consultation. This discrepancy was largely driven by paying out-of-pocket, using alternative insurance, or medication discontinuation or change. These findings have important implications for using pharmacy claims to identify and intervene upon medication non-adherence.

The Indian Health Service and American Indian/Alaska Native Health Outcomes.

The Indian Health Service (IHS) has made huge strides in narrowing health disparities between American Indian and Alaska Native (AI/AN) populations and other racial and ethnic groups. Yet, health disparities experienced by AI/AN people persist, with deep historical roots combined with present-day challenges. Here we review the history of the IHS from colonization to the present-day system, highlight persistent disparities in AI/AN health and health care, and discuss six key present-day challenges: inadequate funding, limited human resources, challenges associated with transitioning services from federal to Tribal control through contracting and compacting, evolving federal and state programs, the need for culturally sensitive services, and the promise and challenges of health technology.

Association Between Cost-Saving Prescription Policy Changes and Adherence to Chronic Disease Medications: an Observational Study.

BACKGROUND: Pharmacy benefit design is one tool for improving access and adherence to medications for the management of chronic disease. OBJECTIVE: We assessed the effects of pharmacy benefit design programs, including a change in pharmacy benefit manager (PBM), institution of a prescription out-of-pocket maximum, and a mandated switch to 90 days' medication supply, on adherence to chronic disease medications over time. DESIGN: We used a difference-in-differences design to assess changes in adherence to chronic disease medications after the transition to new prescription policies. SUBJECTS: We utilized claims data from adults aged 18-64, on ≥ 1 medication for chronic disease, whose insurer instituted the prescription policies (intervention group) and a propensity score-matched comparison group from the same region. MAIN MEASURES: The outcome of interest was adherence to chronic disease medications measured by proportion of days covered (PDC) using pharmacy claims. KEY RESULTS: There were 13,798 individuals in each group after propensity score matching. Compared to the matched control group, adherence in the intervention group decreased in the first quarter of 2015 and then increased back to pre-intervention trends. Specifically, the change in adherence compared to the last quarter of 2014 in the intervention group versus controls was - 3.6 percentage points (pp) in 2015 Q1 (p < 0.001), 0.65 pp in Q2 (p = 0.024), 1.1 pp in Q3 (p < 0.001), and 1.4 pp in Q4 (p < 0.001). CONCLUSIONS: In this cohort of commercially insured adults on medications for chronic disease, a change in PBM accompanied by a prescription out-of-pocket maximum and change to 90 days' supply was associated with short-term disruptions in adherence followed by return to pre-intervention trends. A small improvement in adherence over the year of follow-up may not be clinically significant. These findings have important implications for employers, insurers, or health systems wishing to utilize pharmacy benefit design to improve management of chronic disease.

Trends in buprenorphine treatment disparities during the COVID pandemic in Massachusetts.

Background: Racial, sex, and age disparities in buprenorphine treatment have previously been demonstrated. We evaluated trends in buprenorphine treatment disparities before and after the onset of the COVID pandemic in Massachusetts. Methods: This cross-sectional study used data from an integrated health system comparing 12-months before and after the March 2020 Massachusetts COVID state of emergency declaration, excluding March as a washout period. Among patients with a clinical encounter during the study periods with a diagnosis of opioid use disorder or opioid poisoning, we extracted outpatient buprenorphine prescription rates by age, sex, race and ethnicity, and language. Generating univariable and multivariable Poisson regression models, we calculated the probability of receiving buprenorphine. Results: Among 4,530 patients seen in the period before the COVID emergency declaration, 57.9% received buprenorphine. Among 3,653 patients seen in the second time period, 55.1% received buprenorphine. Younger patients (<24) had a lower likelihood of receiving buprenorphine in both time periods (adjusted prevalence ratio (aPR), 0.56; 95% CI, 0.42-0.75 before vs. aPR, 0.76; 95% CI, 0.60-0.96 after). Male patients had a greater likelihood of receiving buprenorphine compared to female patients in both time periods (aPR: 1.05; 95% CI, 1.00-1.11 vs. aPR: 1.09; 95% CI, 1.02-1.16). Racial disparities emerged in the time period following the COVID pandemic, with non-Hispanic Black patients having a lower likelihood of receiving buprenorphine compared to non-Hispanic white patients in the second time period (aPR, 0.85; 95% CI, 0.72-0.99). Conclusions: Following the onset of the COVID pandemic in Massachusetts, ongoing racial, age, and gender disparities were evident in buprenorphine treatment with younger, Black, and female patients less likely to be treated with buprenorphine across an integrated health system.

Examining the Potential Impact of Race Multiplier Utilization in Estimated Glomerular Filtration Rate Calculation on African-American Care Outcomes.

BACKGROUND: Advancing health equity entails reducing disparities in care. African-American patients with chronic kidney disease (CKD) have poorer outcomes, including dialysis access placement and transplantation. Estimated glomerular filtration rate (eGFR) equations, which assign higher eGFR values to African-American patients, may be a mechanism for inequitable outcomes. Electronic health record-based registries enable population-based examination of care across racial groups. OBJECTIVE: To examine the impact of the race multiplier for African-Americans in the CKD-EPI eGFR equation on CKD classification and care delivery. DESIGN: Cross-sectional study SETTING: Two large academic medical centers and affiliated community primary care and specialty practices. PARTICIPANTS: A total of 56,845 patients in the Partners HealthCare System CKD registry in June 2019, among whom 2225 (3.9%) were African-American. MEASUREMENTS: Exposures included race, age, sex, comorbidities, and eGFR. Outcomes were transplant referral and dialysis access placement. RESULTS: Of 2225 African-American patients, 743 (33.4%) would hypothetically be reclassified to a more severe CKD stage if the race multiplier were removed from the CKD-EPI equation. Similarly, 167 of 687 (24.3%) would be reclassified from stage 3B to stage 4. Finally, 64 of 2069 patients (3.1%) would be reassigned from eGFR > 20 ml/min/1.73 m2 to eGFR ≤ 20 ml/min/1.73 m2, meeting the criterion for accumulating kidney transplant priority. Zero of 64 African-American patients with an eGFR ≤ 20 ml/min/1.73 m2 after the race multiplier was removed were referred, evaluated, or waitlisted for kidney transplant, compared to 19.2% of African-American patients with eGFR ≤ 20 ml/min/1.73 m2 with the default CKD-EPI equation. LIMITATIONS: Single healthcare system in the Northeastern United States and relatively small African-American patient cohort may limit generalizability. CONCLUSIONS: Our study reveals a meaningful impact of race-adjusted eGFR on the care provided to the African-American CKD patient population.

Assessing the quality of shared decision making for elective orthopedic surgery across a large healthcare system: cross-sectional survey study.

BACKGROUND: Clinical guidelines recommend engaging patients in shared decision making for common orthopedic procedures; however, limited work has assessed what is occurring in practice. This study assessed the quality of shared decision making for elective hip and knee replacement and spine surgery at four network-affiliated hospitals. METHODS: A cross-sectional sample of 875 adult patients undergoing total hip or knee joint replacement (TJR) for osteoarthritis or spine surgery for lumbar herniated disc or lumbar spinal stenosis was selected. Patients were mailed a survey including measures of Shared Decision Making (SDMP scale) and Informed, Patient-Centered (IPC) decisions. We examined decision-making across sites, surgeons, and conditions, and whether the decision-making measures were associated with better health outcomes. Analyses were adjusted for clustering of patients within surgeons. RESULTS: Six hundred forty-six surveys (74% response rate) were returned with sufficient responses for analysis. Patients who had TJR reported lower SDMP scores than patients who had spine surgery (2.2 vs. 2.8; p < 0.001). Patients who had TJR were more likely to make IPC decisions (OA = 70%, Spine = 41%; p < 0.001). SDMP and IPC scores varied widely across surgeons, but the site was not predictive of SDMP scores or IPC decisions (all p > 0.09). Higher SDMP scores and IPC decisions were associated with larger improvements in global health outcomes for patients who had TJR, but not patients who had spine surgery. CONCLUSIONS: Measures of shared decision making and decision quality varied among patients undergoing common elective orthopedic procedures. Routine measurement of shared decision making provides insight into areas of strength across these different orthopedic conditions as well as areas in need of improvement.

Comparison of a new 3-item self-reported measure of adherence to medication with pharmacy claims data in patients with cardiometabolic disease.

BACKGROUND: Less than half of patients with cardiometabolic disease consistently take prescribed medications. While health insurers and some delivery organizations use claims to measure adherence, most clinicians do not have access during routine interactions. Self-reported scales exist, but their practical utility is often limited by length or cost. By contrast, the accuracy of a new 3-item self-reported measure has been demonstrated in individuals with HIV. We evaluated its concordance with claims-based adherence measures in cardiometabolic disease. METHODS: We used data from a recently-completed pragmatic trial of patients with cardiometabolic conditions. After 12 months of follow-up, intervention subjects were mailed a survey with the 3-item measure that queries about medication use in the prior 30 days. Responses were linearly transformed and averaged. Adherence was also measured in claims in month 12 and months 1-12 of the trial using proportion of days covered (PDC) metrics. We compared validation metrics for non-adherence for self-report (average <0.80) compared with claims (PDC <0.80). RESULTS: Of 459 patients returning the survey (response rate: 43.5%), 50.1% were non-adherent in claims in month 12 while 20.9% were non-adherent based on the survey. Specificity of the 3-item metric for non-adherence was high (month 12: 0.83). Sensitivity was relatively poor (month 12: 0.25). Month 12 positive and negative predictive values were 0.59 and 0.52, respectively. CONCLUSIONS: A 3-item self-reported measure has high specificity but poor sensitivity for non-adherence versus claims in cardiometabolic disease. Despite this, the tool could help target those needing adherence support, particularly in the absence of claims data.

Predictors of Prolonged Opioid Use Following Colectomy.

BACKGROUND: The United States is in the middle of an opioid epidemic. Gastrointestinal surgery has been ranked in the top 3 surgical subspecialties for highest opioid prescribing. OBJECTIVE: The goal of this study is to determine the rate of and risk factors for prolonged opioid use following colectomy. DESIGN: This study utilized data (2015-2017) from the American College of Surgeons National Surgical Quality Improvement Program from 5 institutions. SETTINGS: This study was conducted at 2 academic and 3 community hospitals. PATIENTS: Included were 1243 patients who underwent colectomy. MAIN OUTCOME MEASURES: The primary outcome was rate of prolonged opioid use defined as a new opioid prescription 90 to 180 days postoperatively. RESULTS: A total of 132 (10.6%) patients were prolonged opioid users. In univariate analysis, patients who were prolonged opioid users were significantly more likely to have had more than one opioid prescription in the prior year, to have a higher ASA classification, to undergo an open procedure, to have an ostomy created, and to be discharged with a high quantity of opioids (all p < 0.05). Prolonged opioid users were significantly more likely to have a complication (p = 0.007) or readmission (p = 0.003) within 30 days of the index procedure. In multivariable analysis, prior opioid use (OR, 2.6; 95% CI, 1.6-4.2; p < 0.001), ostomy creation (OR, 2.1; 95% CI,1.2-3.7; p = 0.01), higher quantity of opioid prescription at discharge (OR, 1.9; 95% CI,1.1-3.3; p = 0.03), higher ASA classification (OR, 1.7; 95% CI, 1.1-2.6; p = 0.02), and hospital readmission (OR, 2.0; 95% CI, 1.2-3.4; p = 0.01) were independent predictors of prolonged opioid use. LIMITATIONS: This study is a retrospective review, and all variables related to prolonged opioid use are not collected in the data. CONCLUSIONS: A significant proportion of patients undergoing colectomy become prolonged opioid users. We have identified risk factors for prolonged postoperative opioid use, which may allow for improved patient education and targets for intervention preoperatively, as well as implementation of programs for monitoring and cessation of opioid use in the postoperative period.

La cirugía gastrointestinal ha sido clasificada entre las tres subespecialidades quirúrgicas principales para la prescripción más alta de opioides. OBJETIVO: El objetivo de este estudio es determinar la tasa y los factores de riesgo para el uso prolongado de opioides después de la colectomía. DISEÑO:: Este estudio utilizó datos (2015-2017) del Programa Nacional de Mejoramiento de la Calidad Quirúrgica del Colegio Americano de Cirujanos de cinco instituciones. MARCO: Dos hospitales académicos y tres comunitarios. PACIENTES: 1,243 pacientes sometidos a una colectomía. MEDIDAS DE RESULTADO PRINCIPALES: El resultado primario fue la tasa de uso prolongado de opioides, definida como una nueva receta de opioides entre 90 y 180 días después de la operación. RESULTADOS: Un total de 132 (10.6%) pacientes fueron usuarios de opioides por tiempo prolongado. En el análisis univariado, los pacientes que eran usuarios prolongados de opioides tenían una probabilidad significativamente mayor de haber tenido más de una receta de opioides en el año anterior, tenían una clasificación más alta de la Asociación Americana de Anestesiólogos, se sometieron a un procedimiento abierto, se les creó una ostomía y se les dio de alta con una cantidad grande de opioides (todos p < 0.05). Los usuarios de opioides prolongados fueron significativamente más propensos a tener una complicación (p = 0.007) o readmisión (p = 0.003) dentro de los 30 días del procedimiento índice. En el análisis multivariado, el uso previo de opioides (OR, 2.6; IC 95%, 1.6-4.2; p < 0.001), creación de ostomía (OR, 2.1; IC 95%, 1.2-3.7; p = 0.01), mayor cantidad de prescripción de opioides al dar de alta (OR, 1.9; IC 95%, 1.1-3.3; p = 0.03), clasificación más alta de la Asociación Americana de Anestesiólogos (OR, 1.7; IC 95%, 1.1-2.6; p = 0.02) y reingreso hospitalario (OR, 2.0; IC del 95%, 1.2-3.4, p = 0.01) fueron predictores independientes del uso prolongado de opioides. LIMITACIONES: Este estudio es una revisión retrospectiva y todos los variables relacionadas con el uso prolongado de opioides no se colectaron en los datos. CONCLUSIONES: Una proporción significativa de pacientes con colectomía se convierten en usuarios prolongados de opioides. Hemos identificado factores de riesgo para el uso prolongado de opioides postoperatorios, que pueden permitir una mejor educación del paciente y objetivos para la intervención preoperatoria, así como la implementación de programas para la supervisión y cese del uso de opioides en el período postoperatorio.

Development of an electronic health record-based chronic kidney disease registry to promote population health management.

BACKGROUND: Electronic health record (EHR) based chronic kidney disease (CKD) registries are central to population health strategies to improve CKD care. In 2015, Partners Healthcare System (PHS), encompassing multiple academic and community hospitals and outpatient care facilities in Massachusetts, developed an EHR-based CKD registry to identify opportunities for quality improvement, defined as improvement on both process measures and outcomes measures associated with clinical care. METHODS: Patients are included in the registry based on the following criteria: 1) two estimated glomerular filtration rate (eGFR) results < 60 ml/min/1.73m2 separated by 90 days, including the most recent eGFR being < 60 ml/min/1.73m2; or 2) the most recent two urine protein values > 300 mg protein/g creatinine on either urine total protein/creatinine ratio or urine albumin/creatinine ratio; or 3) an EHR problem list diagnosis of end stage renal disease (ESRD). The registry categorizes patients by CKD stage and includes rates of annual testing for eGFR and proteinuria, blood pressure control, use of angiotensin converting enzyme inhibitors (ACE-Is) or angiotensin receptor blockers (ARBs), nephrotoxic medication use, hepatitis B virus (HBV) immunization, vascular access placement, transplant status, CKD progression risk; number of outpatient nephrology visits, and hospitalizations. RESULTS: The CKD registry includes 60,503 patients and has revealed several opportunities for care improvement including 1) annual proteinuria testing performed for 17% (stage 3) and 31% (stage 4) of patients; 2) ACE-I/ARB used in 41% (stage 3) and 46% (stage 4) of patients; 3) nephrotoxic medications used among 23% of stage 4 patients; and 4) 89% of stage 4 patients lack HBV immunity. For advanced CKD patients there are opportunities to improve vascular access placement, transplant referrals and outpatient nephrology contact. CONCLUSIONS: A CKD registry can identify modifiable care gaps across the spectrum of CKD care and enable population health strategy implementation. No linkage to Social Security Death Master File or US Renal Data System (USRDS) databases limits our ability to track mortality and progression to ESRD.

Choosing wisely--the politics and economics of labeling low-value services.

More than 40 medical specialties have identified "Choosing Wisely" lists of five overused or low-value services. But these services vary widely in potential impact on care and spending, and specialty societies often name other specialties' services as low value.

Physician and Patient Views on Public Physician Rating Websites: A Cross-Sectional Study.

BACKGROUND: Numerical ratings and narrative comments about physicians are increasingly available online. These physician rating websites include independent websites reporting crowd-sourced data from online users and health systems reporting data from their internal patient experience surveys. OBJECTIVE: To assess patient and physician views on physician rating websites. DESIGN: Cross-sectional physician (electronic) and patient (paper) surveys conducted in August 2015. PARTICIPANTS: Eight hundred twenty-eight physicians (response rate 43%) affiliated with one of four hospitals in a large accountable care organization in eastern Massachusetts; 494 adult patients (response rate 34%) who received care in this system in May 2015. MAIN MEASURES: Use and perceptions of physician rating websites. KEY RESULTS: Fifty-three percent of physicians and 39% of patients reported visiting a physician rating website at least once. Physicians reported higher levels of agreement with the accuracy of numerical data (53%) and narrative comments (62%) from health system patient experience surveys compared to numerical data (36%) and narrative comments (36%) on independent websites. Patients reported higher levels of agreement with trusting the accuracy of data obtained from independent websites (57%) compared to health system patient experience surveys (45%). Twenty-one percent of physicians and 51% of patients supported posting narrative comments online for all consumers. The majority (78%) of physicians believed that posting narrative comments online would increase physician job stress; smaller proportions perceived a negative effect on the physician-patient relationship (46%), health care overuse (34%), and patient-reported experiences of care (33%). Over one-fourth of patients (29%) believed that posting narrative comments would cause them to be less open. CONCLUSIONS: Physicians and patients have different views on whether independent or health system physician rating websites are the more reliable source of information. Their views on whether such data should be shared on public websites are also discordant.

How Primary Care Physicians Integrate Price Information into Clinical Decision-Making.

BACKGROUND: Little is known about how primary care physicians (PCPs) in routine outpatient practice use paid price information (i.e., the amount that insurers finally pay providers) in daily clinical practice. OBJECTIVE: To describe the experiences of PCPs who have had paid price information on tests and procedures for at least 1 year. DESIGN: Cross-sectional study using semi-structured interviews and the constant comparative method of qualitative analysis. PARTICIPANTS: Forty-six PCPs within an accountable care organization. INTERVENTION: Via the ordering screen of their electronic health record, PCPs were presented with the median paid price for commonly ordered tests and procedures (e.g., blood tests, x-rays, CTs, MRIs). APPROACH: We asked PCPs for (a) their "gut reaction" to having paid price information, (b) the situations in which they used price information in clinical decision-making separate from or jointly with patients, (c) their thoughts on who bore the chief responsibility for discussing price information with patients, and (d) suggestions for improving physician-targeted price information interventions. KEY RESULTS: Among "gut reactions" that ranged from positive to negative, all PCPs were more interested in having patient-specific price information than paid prices from the practice perspective. PCPs described that when patients' out-of-pocket spending concerns were revealed, price information helped them engage patients in conversations about how to alter treatment plans to make them more affordable. PCPs stated that having price information only slightly altered their test-ordering patterns and that they avoided mentioning prices when advising patients against unnecessary testing. Most PCPs asserted that physicians bear the chief responsibility for discussing prices with patients because of their clinical knowledge and relationships with patients. They wished for help from patients, practices, health plans, and society in order to support price transparency in healthcare. CONCLUSIONS: Physician-targeted price transparency efforts may provide PCPs with the information they need to respond to patients' concerns regarding out-of-pocket affordability rather than that needed to change test-ordering habits.

A Randomized Trial of Displaying Paid Price Information on Imaging Study and Procedure Ordering Rates.

BACKGROUND: Prior studies have demonstrated how price transparency lowers the test-ordering rates of trainees in hospitals, and physician-targeted price transparency efforts have been viewed as a promising cost-controlling strategy. OBJECTIVE: To examine the effect of displaying paid-price information on test-ordering rates for common imaging studies and procedures within an accountable care organization (ACO). DESIGN: Block randomized controlled trial for 1 year. SUBJECTS: A total of 1205 fully licensed clinicians (728 primary care, 477 specialists). INTERVENTION: Starting January 2014, clinicians in the Control arm received no price display; those in the intervention arms received Single or Paired Internal/External Median Prices in the test-ordering screen of their electronic health record. Internal prices were the amounts paid by insurers for the ACO's services; external paid prices were the amounts paid by insurers for the same services when delivered by unaffiliated providers. MAIN MEASURES: Ordering rates (orders per 100 face-to-face encounters with adult patients): overall, designated to be completed internally within the ACO, considered "inappropriate" (e.g., MRI for simple headache), and thought to be "appropriate" (e.g., screening colonoscopy). KEY RESULTS: We found no significant difference in overall ordering rates across the Control, Single Median Price, or Paired Internal/External Median Prices study arms. For every 100 encounters, clinicians in the Control arm ordered 15.0 (SD 31.1) tests, those in the Single Median Price arm ordered 15.0 (SD 16.2) tests, and those in the Paired Prices arms ordered 15.7 (SD 20.5) tests (one-way ANOVA p-value 0.88). There was no difference in ordering rates for tests designated to be completed internally or considered to be inappropriate or appropriate. CONCLUSIONS: Displaying paid-price information did not alter how frequently primary care and specialist clinicians ordered imaging studies and procedures within an ACO. Those with a particular interest in removing waste from the health care system may want to consider a variety of contextual factors that can affect physician-targeted price transparency.

Delayed Workup of Rectal Bleeding in Adult Primary Care: Examining Process-of-Care Failures.

BACKGROUND: Although delayed colorectal cancer diagnoses figure prominently in medical malpractice claims, little is known about the quality of primary care clinicians' workup of rectal bleeding. METHODS: In this study, 438 patients were identified using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes for rectal bleeding, hemorrhoids, and blood in the stool at 10 Boston adult primary care practices. Following nurse chart abstraction, physician reviewers assessed the overall quality of care and key care processes. Subjects' characteristics and physician reviewers' processes-of-care assessments were tabulated, and logistic regression models were used to examine the association of process failures with overall quality and guideline concordance. RESULTS: Although reviewers judged the overall quality of care to be good or excellent in 337 (77%) of 438 cases, 312 (71%) patients experienced at least one process-of-care failure in the workup of rectal bleeding. Clinicians failed to obtain an adequate family history in 38% of cases, complete a pertinent physical exam in 23%, and order laboratory tests in 16%. Failure to order or perform tests, or to make follow-up plans were associated with increased odds of poor or fair care. Guideline concordance bore little relationship with quality judgments. Reviewers judged that 128 delays could have been reduced or prevented. CONCLUSION: Process-of-care failures among adult primary care patients with rectal bleeding were frequent and associated with fair or poor quality. Educating practitioners and creating systems to ensure adequate history taking, physical examination, and processes for ordering, performing, and interpreting diagnostic tests may improve performance.

Rationale and design of the Study of a Tele-pharmacy Intervention for Chronic diseases to Improve Treatment adherence (STIC2IT): A cluster-randomized pragmatic trial.

BACKGROUND: Approximately half of patients with chronic cardiometabolic conditions are nonadherent with their prescribed medications. Interventions to improve adherence have been only modestly effective because they often address single barriers to adherence, intervene at single points in time, or are imprecisely targeted to patients who may not need adherence assistance. OBJECTIVE: To evaluate the effect of a multicomponent, behaviorally tailored pharmacist-based intervention to improve adherence to medications for diabetes, hypertension, and hyperlipidemia. TRIAL DESIGN: The STIC2IT trial is a cluster-randomized pragmatic trial testing the impact of a pharmacist-led multicomponent intervention that uses behavioral interviewing, text messaging, mailed progress reports, and video visits. Targeted patients are those who are nonadherent to glucose-lowering, antihypertensive, or statin medications and who also have evidence of poor disease control. The intervention is tailored to patients' individual health barriers and their level of health activation. We cluster-randomized 14 practice sites of a large multispecialty group practice to receive either the pharmacist-based intervention or usual care. STIC2IT has enrolled 4,076 patients who will be followed up for 12months after randomization. The trial's primary outcome is medication adherence, assessed using pharmacy claims data. Secondary outcomes are disease control and health care resource utilization. CONCLUSION: This trial will determine whether a technologically enabled, behaviorally targeted pharmacist-based intervention results in improved adherence and disease control. If effective, this strategy could be a scalable method of offering tailored adherence support to those with the greatest clinical need.

The role of neighborhood characteristics and the built environment in understanding racial/ethnic disparities in childhood obesity.

BACKGROUND: Childhood obesity prevalence remains high and racial/ethnic disparities may be widening. Studies have examined the role of health behavioral differences. Less is known regarding neighborhood and built environment mediators of disparities. The objective of this study was to examine the extent to which racial/ethnic disparities in elevated child body mass index (BMI) are explained by neighborhood socioeconomic status (SES) and built environment. METHODS: We collected and analyzed race/ethnicity, BMI, and geocoded address from electronic health records of 44,810 children 4 to 18years-old seen at 14 Massachusetts pediatric practices in 2011-2012. Main outcomes were BMI z-score and BMI z-score change over time. We used multivariable linear regression to examine associations between race/ethnicity and BMI z-score outcomes, sequentially adjusting for neighborhood SES and the food and physical activity environment. RESULTS: Among 44,810 children, 13.3% were black, 5.7% Hispanic, and 65.2% white. Compared to white children, BMI z-scores were higher among black (0.43units [95% CI: 0.40-0.45]) and Hispanic (0.38 [0.34-0.42]) children; black (0.06 [0.04-0.08]), but not Hispanic, children also had greater increases in BMI z-score over time. Adjusting for neighborhood SES substantially attenuated BMI z-score differences among black (0.30 [0.27-0.34]) and Hispanic children (0.28 [0.23-0.32]), while adjustment for food and physical activity environments attenuated the differences but to a lesser extent than neighborhood SES. CONCLUSIONS: Neighborhood SES and the built environment may be important drivers of childhood obesity disparities. To accelerate progress in reducing obesity disparities, interventions must be tailored to the neighborhood contexts in which families live.

Overuse of colonoscopy for colorectal cancer screening and surveillance.

BACKGROUND: Ongoing efforts to increase colorectal cancer (CRC) screening rates have raised concerns that these exams may be overused, thereby subjecting patients to unnecessary risks and wasting healthcare resources. OBJECTIVE: Our aim was to measure overuse of screening and surveillance colonoscopies among average-risk adults, and to identify correlates of overuse. DESIGN, SETTING, AND PARTICIPANTS: Our approach was a retrospective cohort study using electronic health record data for patients 50-65 years old with no personal history of CRC or colorectal adenomas with an incident CRC screening colonoscopy from 2001 to 2010 within a multispecialty physician group practice. MAIN OUTCOME MEASURES: We measured time to next screening or surveillance colonoscopy and predictors of overuse (exam performed more than one year earlier than guideline recommended intervals) of colonoscopies. KEY RESULTS: We identified 1,429 adults who had an incident colonoscopy between 2001 and 2010, and they underwent an additional 871 screening or surveillance colonoscopies during a median follow-up of 6 years. Most follow-up screening colonoscopies (88%) and many surveillance colonoscopies (49%) repeated during the study represented overuse. Time to next colonoscopy after incident screening varied by exam findings (no polyp: median 6.9 years, interquartile range [IQR]: 5.1-10.0; hyperplastic polyp: 5.7 years, IQR: 4.9-9.7; low-risk adenoma: 5.1 years, IQR: 3.3-6.3; high-risk adenoma: 2.9 years, IQR: 2.0-3.4, p < 0.001). In logistic regression models of colonoscopy overuse, an endoscopist recommendation for early follow-up was strongly associated with overuse of screening colonoscopy (OR 6.27, 95% CI: 3.15-12.50) and surveillance colonoscopy (OR 13.47, 95% CI 6.61-27.46). In a multilevel logistic regression model, variation in the overuse of screening colonoscopy was significantly associated with the endoscopist performing the previous exam. CONCLUSIONS: Overuse of screening and surveillance exams are common and should be monitored by healthcare systems.

Choosing wisely: prevalence and correlates of low-value health care services in the United States.

BACKGROUND: Specialty societies in the United States identified low-value tests and procedures that contribute to waste and poor health care quality via implementation of the American Board of Internal Medicine Foundation's Choosing Wisely initiative. OBJECTIVE: To develop claims-based algorithms, to use them to estimate the prevalence of select Choosing Wisely services and to examine the demographic, health and health care system correlates of low-value care at a regional level. DESIGN: Using Medicare data from 2006 to 2011, we created claims-based algorithms to measure the prevalence of 11 Choosing Wisely-identified low-value services and examined geographic variation across hospital referral regions (HRRs). We created a composite low-value care score for each HRR and used linear regression to identify regional characteristics associated with more intense use of low-value services. PATIENTS: Fee-for-service Medicare beneficiaries over age 65. MAIN MEASURES: Prevalence of selected Choosing Wisely low-value services. KEY RESULTS: The national average annual prevalence of the selected Choosing Wisely low-value services ranged from 1.2% (upper urinary tract imaging in men with benign prostatic hyperplasia) to 46.5% (preoperative cardiac testing for low-risk, non-cardiac procedures). Prevalence across HRRs varied significantly. Regional characteristics associated with higher use of low-value services included greater overall per capita spending, a higher specialist to primary care ratio and higher proportion of minority beneficiaries. CONCLUSIONS: Identifying and measuring low-value health services is a prerequisite for improving quality and eliminating waste. Our findings suggest that the delivery of wasteful and potentially harmful services may be a fruitful area for further research and policy intervention for HRRs with higher per-capita spending. These findings should inform action by physicians, health systems, policymakers, payers and consumer educators to improve the value of health care by targeting services and areas with greater use of potentially inappropriate care.
