Reduced Unplanned Care and Disease Activity and Increased Quality of Life After Patient Enrollment in an Inflammatory Bowel Disease Medical Home

BACKGROUND & AIMS: Specialty medical homes (SMHs) are a new health care model in which a multidisciplinary team and specialists manage patients with chronic diseases. As part of a large integrated payer–provider network, we formed an inflammatory bowel diseases (IBDs) SMH and investigated its effects on health care use, disease activity, and quality of life (QoL). METHODS: We performed a retrospective analysis of 322 patients (58% female; mean age, 34.6 y; 62% with Crohns disease; 32% with prior IBD surgery) enrolled in an IBD SMH, in conjunction with the University of Pittsburgh Medical Center Health Plan, from June 2015 through July 2016. Patients had at least 1 year of follow up. We evaluated changes in numbers of emergency department visits and hospitalizations from the year before vs after SMH enrollment. Secondary measures included IBD activity assessments and QoL. RESULTS: Compared to the year before IBD SMH enrollment, patients had a 47.3% reduction in emergency department visits (P < .0001) and a 35.9% reduction in hospitalizations (P = .008). In the year following IBD SMH enrollment, patients had significant reductions in the median Harvey–Bradshaw Index score (reduced from 4 to 3.5; P = .002), and median ulcerative colitis activity index score (from 4 to 3; P = .0003), and increases in QoL (median short inflammatory bowel disease questionnaire score increased from 50 to 51.8; P < .0001). Patients in the most extreme (highest and lowest) quartiles had the most improvement when we compared scores at baseline vs after enrollment. Based on multivariable regression analysis, use of corticosteroids (odds ratio [OR], 2.72; 95% CI, 1.32–5.66; P = .007) or opioids (OR, 3.20; 95% CI, 1.32–7.78; P = .01), and low QoL (OR, 4.44; 95% CI, 1.08–18.250; P = .04) at enrollment were significantly associated with persistent emergency department visits and hospitalizations. CONCLUSIONS: We found development of an IBD SMH to be feasible and significantly reduce unplanned care and disease activity and increase patient QoL 1 year after enrollment.

Association of Changes in Medication Use and Adherence With Accountable Care Organization Exposure in Patients With Cardiovascular Disease or Diabetes

Importance Many of the quality measures used to assess accountable care organization (ACO) performance in the Medicare Shared Savings Program (MSSP) focus on disease control and medication use among patients with cardiovascular disease and diabetes. To date, the association between participation in the MSSP by provider organizations and medication use or adherence among their patients with cardiovascular disease or diabetes has not been described. Objective To assess the association between exposure to the MSSP and changes in the use of and adherence to common antihypertensive, lipid-lowering, and hypoglycemic medications. Design, Setting, and Participants Fee-for-service Medicare claims from January 1, 2009, to December 31, 2014, were used to conduct difference-in-differences comparisons of changes for ACO-attributed beneficiaries from before the start of ACO contracts to 2014 with concurrent changes for beneficiaries attributed to local non-ACO providers (control group). A random 20% sample of Medicare beneficiaries contributing 4 482 168 to 10 849 224 beneficiary-years for analysis from 2009 to 2014, depending on the drug class, was examined. Differential changes were estimated separately for cohorts of ACOs entering the MSSP in 2012, 2013, and 2014. Data analysis was conducted from November 1, 2016, to April 5, 2017. Exposures Patient attribution to an ACO after entry into the MSSP. Main Outcomes and Measures Any use (at least 1 prescription fill) and proportion of days covered (PDC), a standard claims-based measure of adherence, assessed for each of 6 drug classes: statins, angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers, &bgr;-blockers, thiazide diuretics, calcium channel blockers, and metformin. Results Differences in patient characteristics between the MSSP and control group were generally small after geographic adjustment and changed minimally from the precontract period to 2014. There were no significant differential changes in medication use from the precontract period to 2014 for any cohort of MSSP ACOs in any drug class, except for a slight differential increase in the use of thiazides among beneficiaries with hypertension in the 2013 entry cohort (adjusted differential change, 0.5 percentage point; 95% CI, 0.1-0.8 percentage points; or 1.5% of the overall percentage using thiazides [33.4%], P = .01). Similarly, there were no significant differential changes in PDC among beneficiaries with at least 1 prescription fill, except for slight differential increases in the PDC for &bgr;-blockers in the 2012 entry cohort (adjusted differential change, 0.3 percentage point; 95% CI, 0.1-0.5 percentage points; or 0.4% of the mean PDC [82.3%], P = .003) and for metformin in the 2012 and 2013 cohorts (adjusted differential change, 0.5 percentage point; 95% CI, 0.1-0.9 percentage points; or 0.6% of the mean PDC [78.2%], P = .01 for both). Conclusions and Relevance Exposure to the MSSP has not been associated with meaningful changes in medication use or adherence among patients with cardiovascular disease and diabetes.

Automatable algorithms to identify nonmedical opioid use using electronic data: a systematic review

Objective Improved methods to identify nonmedical opioid use can help direct health care resources to individuals who need them. Automated algorithms that use large databases of electronic health care claims or records for surveillance are a potential means to achieve this goal. In this systematic review, we reviewed the utility, attempts at validation, and application of such algorithms to detect nonmedical opioid use. Materials and Methods We searched PubMed and Embase for articles describing automatable algorithms that used electronic health care claims or records to identify patients or prescribers with likely nonmedical opioid use. We assessed algorithm development, validation, and performance characteristics and the settings where they were applied. Study variability precluded a meta-analysis. Results Of 15 included algorithms, 10 targeted patients, 2 targeted providers, 2 targeted both, and 1 identified medications with high abuse potential. Most patient-focused algorithms (67%) used prescription drug claims and/or medical claims, with diagnosis codes of substance abuse and/or dependence as the reference standard. Eleven algorithms were developed via regression modeling. Four used natural language processing, data mining, audit analysis, or factor analysis. Discussion Automated algorithms can facilitate population-level surveillance. However, there is no true gold standard for determining nonmedical opioid use. Users must recognize the implications of identifying false positives and, conversely, false negatives. Few algorithms have been applied in real-world settings. Conclusion Automated algorithms may facilitate identification of patients and/or providers most likely to need more intensive screening and/or intervention for nonmedical opioid use. Additional implementation research in real-world settings would clarify their utility.

Encouraging Medicare Advantage Enrollees to Switch to Higher Quality Plans: Assessing the Effectiveness of a “Nudge” Letter

There are considerable quality differences across private Medicare Advantage insurance plans, so it is important that beneficiaries make informed choices. During open enrollment for the 2013 coverage year, the Centers for Medicare & Medicaid Services sent letters to beneficiaries enrolled in low-quality Medicare Advantage plans (i.e., plans rated less than 3 stars for at least 3 consecutive years by Medicare) explaining the stars and encouraging them to reexamine their choices. To understand the effectiveness of these low-cost, behavioral “nudge” letters, we used a beneficiary-level national retrospective cohort and performed multivariate regression analysis of plan selection during the 2013 open enrollment period among those enrolled in plans rated less than 3 stars. Our analysis controls for beneficiary demographic characteristics, health and health care spending risks, the availability of alternative higher rated plan options in their local market, and historical disenrollment rates from the plans. We compared the behaviors of those beneficiaries who received the nudge letters with those who enrolled in similar poorly rated plans but did not receive such letters. We found that beneficiaries who received the nudge letter were almost twice as likely (28.0% [95% confidence interval = 27.7%, 28.2%] vs. 15.3% [95% confidence interval = 15.1%, 15.5%]) to switch to a higher rated plan compared with those who did not receive the letter. White beneficiaries, healthier beneficiaries, and those residing in areas with more high-performing plan choices were more likely to switch plans in response to the nudge. Our findings highlight both the importance and efficacy of providing timely and actionable information to beneficiaries about quality in the insurance marketplace to facilitate informed and value-based coverage decisions.

A Public-Private Partnership for Proactive Pharmacy-Based Outreach and Acquisition of Needed Medication in Advance of Severe Winter Weather

A Public-Private Partnership for Proactive Pharmacy-Based Outreach and Acquisition of Needed Medication in Advance of Severe Winter Weather In the setting of a natural disaster, patients with chronic conditions may have difficulty accessing their prescribed medications, because they are left behind in an evacuation or because a refill cannot be obtained from the pharmacy in the aftermath, which happened after hurricanes Sandy and Katrina.1,2 Some natural disasters are forecasted several days in advance of their arrival, providing an opportunity for preparedness by the public and private sectors. Communication with patients about upcoming storms and the need to refill medications may ensure medication access and prevent exacerbations of chronic diseases. In a collaboration between the US Department of Health and Human Services and CVS pharmacies, we assessed whether consumer-centric outreach to encourage medication acquisition would increase access to prescribed medications.

Impact of community pharmacist-provided preventive services on clinical, utilization, and economic outcomes: An umbrella review

Preventable diseases and late diagnosis of disease impose great clinical and economic burden for health care systems, especially in the current juncture of rising medical expenditures. Under these circumstances, community pharmacies have been identified as accessible venues to receive preventive services. This umbrella review aims to examine existing evidence on the impact of community pharmacist-provided preventive services on clinical, utilization, and economic outcomes in the United States (US). We included systematic reviews, narrative reviews and meta-analyses published in English between January 2007 and October 2017. Of 2742 references identified by our search strategy, a total of 13 research syntheses met our inclusion criteria. Included reviews showed that community pharmacists are effective at increasing immunization rates, supporting smoking cessation, managing hormonal contraception therapies, and identifying patients at high risk for certain diseases. Moreover, evidence suggests that community pharmacies are especially well-positioned for the provision of preventive services due to their convenient location and extended hours of operation. There is general agreement on the positive impact of community pharmacists in increasing access to preventive health, particularly among patients who otherwise would not be reached by other healthcare providers. The provision of preventive services at US community pharmacies is feasible and effective, and has potential for improving patient outcomes and health system efficiency. However, high-quality evidence is still lacking. As the healthcare landscape shifts towards a value-based framework, it will be important to conduct robust studies that further evaluate the impact of community pharmacist-provided preventive services on utilization and economic outcomes.
