The morbidity and mortality associated with COPD exacts a considerable economic burden. Comorbidities in COPD are associated with poor health outcomes and increased costs. Our objective was to assess the impact of comorbidities on COPD-associated costs in a large administrative claims dataset. This was a retrospective observational study of data from the Truven Health MarketScan Commercial Claims and Encounters and the MarketScan Medicare Supplemental Databases from January 1, 2009, to September 30, 2012. Resource consumption was measured from the index date (date of first occurrence of non-rule-out COPD diagnosis) to 360 days after the index date. Resource use (all-cause and disease-specific [ie, COPD- or asthma-related] ED visits, hospitalizations, office visits, other outpatient visits, and total length of hospital stay) and health-care costs (all-cause and disease-specific costs for ED visits, hospitalizations, office visits, and other outpatient visits and medical, prescription, and total health-care costs) were assessed. Generalized linear models were used to evaluate the impact of comorbidities on total health-care costs, adjusting for age, sex, geographic location, baseline health-care use, employment status, and index COPD medication. Among 183,681 patients with COPD, the most common comorbidities were cardiovascular disease (34.8%), diabetes (22.8%), asthma (14.7%), and anemia (14.2%). Most patients (52.8%) had one or two comorbidities of interest. The average all-cause total health-care costs from the index date to 360 days after the index date were highest for patients with chronic kidney disease ($41,288) and anemia ($38,870). The impact on total health-care costs was greatest for anemia ($10,762 more, on average, than a patient with COPD without anemia). Our analysis demonstrated that high resource use and costs were associated with COPD and multiple comorbidities.

Purpose: The all-cause readmission rate within 30 days of index admissions for chronic obstructive pulmonary disease (COPD) was approximately 21% in the United States in 2008. This study aimed to examine patient and clinical characteristics predicting 30-day unplanned readmissions for an initial COPD hospitalization and to determine those predictors’ importance. Patients and methods: A retrospective study was conducted in patients with COPD-related hospitalizations using commercial claims data from 2010 to 2012. The primary outcome was all-cause unplanned readmission, with secondary outcomes being COPD as primary diagnosis and COPD as any diagnosis unplanned readmissions. Factors predicting unplanned readmissions encompassed demographic, pharmacy, and medical variables identified at baseline and during the index hospitalization. Dominance analysis was conducted to rank the predictors in terms of importance, defined as the contribution to change in model fit of a predictor by itself and in combination with other predictors. Results: After applying the inclusion and exclusion criteria, 18,282 patients with index COPD-related admissions were identified. Among them, the rates of unplanned readmissions with COPD as primary diagnosis, COPD as any diagnosis, and all-cause were 2.6%, 5.6%, and 7.3%, respectively. For each outcome, the readmission group was slightly older, had a greater COPD severity score, and required a longer length of stay. Moreover, the readmission group had larger proportions of patients with comorbidities, dyspnea/shortness of breath, intensive care unit stay, or ventilator use, compared to the non-readmission group. Dominance analysis revealed that the three most important predictors – heart failure/heart disease, anemia, and COPD severity score – accounted for 56% of the predicted variance in all-cause unplanned readmissions. Conclusion: Overall, COPD severity score and heart failure/heart disease emerged as important factors in predicting 30-day unplanned readmissions across all three outcomes. Results from dominance analysis suggest looking beyond COPD-specific complications and focusing on comorbid conditions highly associated with COPD in order to lower all-cause unplanned readmissions.

BACKGROUND: An integrated health care system with its own regional health plan located in Texas implemented a pharmacist-led diabetes medication management program (MMP) to treat type 2 diabetic patients (baseline A1c > 7.5%). The MMP formed collaborative practice agreements with the system’s physicians to allow ambulatory care pharmacists to modify and adjust diabetic drug regimens when appropriate. Enrolled MMP patients received personalized visits with ambulatory care pharmacists and a copay waiver on diabetes medications. OBJECTIVE: To study the outcomes of an outpatient, pharmacist-led MMP, along with a copay waiver on diabetes drugs, in treating adults with type 2 diabetes mellitus over a 2-year period compared with standard care practice. METHODS: This retrospective study employed a quasi-experimental design and used medical claims, pharmacy claims, eligibility data, and electronic medical records. Patients aged 18 to 62 years, who were diagnosed with type 2 diabetes mellitus, and had at least 1 diabetes-related pharmacy claim in the year before the MMP, as well as continuous enrollment in the health plan, were included. Patients enrolled in the pharmacist-led MMP for at least 2 years (n =75) were matched to standard care patients (n =75) on age, gender, baseline A1c, insulin use, and physical comorbidity. The primary outcome was the 2-year change in A1c. Secondary outcomes included inpatient costs, outpatient costs, and pharmacy costs from the baseline period (year before enrollment) compared with the follow-up period (second year of enrollment). RESULTS: After matching MMP patients (n = 75) to control patients (n = 75), the baseline A1c (9.30 and 9.26), the mean age (53.0 and 53.3, respectively), the Selim Physical Score (3.32 and 3.26, respectively), and the use of insulin (56.0% and 56.0%, respectively) were similar in both groups. MMP patients had a greater mean reduction in A1c compared with standard care patients (-1.24 vs. -0.59, P = 0.009) from baseline to after 2 years. After 2 years, the A1c for MMP patients was significantly lower compared with control patients (8.06 vs.8.67, respectively, P = 0.014). There was also a difference in A1c after 1 year for MMP patients versus control patients (8.18 and 8.69, respectively, P = 0.012). CONCLUSIONS: A pharmacist-led diabetes MMP, combined with a diabetes drug copay waiver, was effective in significantly reducing A1c over a 2-year period for type 2 diabetic patients in this regional health plan. DISCLOSURES: Scott & White Health Plan supported this research by funding the copay waivers used in this study.

Objectives The aim of this study was to assess the cost effectiveness of allogeneic umbilical cord blood-derived mesenchymal stem cells with sodium hyaluronate (hUCB-MSC) compared with microfracture in patients with knee cartilage defects caused by osteoarthritis (OA) in South Korea. Methods A partitioned survival model approach was taken consisting of five mutually exclusive health states: excellent, good, fair, poor, and death over a 20-year time horizon. Utility values were obtained from a randomized clinical trial. Cost data were extracted from a database provided by the Health Insurance Review & Assessment Service, and the utilization of healthcare services was estimated from an expert panel of orthopedic surgeons using a structured questionnaire. The incremental cost-effectiveness ratio (ICER) in terms of quality-adjusted life-years (QALY) was calculated. Deterministic and probabilistic sensitivity analyses were performed. Results In the base case, the incremental costs of US$14,410 for hUCB-MSC therapy along with its associated QALY gain of 0.857 resulted in an ICER of US$16,812 (₩18,790,773) per QALY (95% confidence interval [CI] US$13,408–US$20,828) when compared with microfracture treatment from a healthcare payer perspective. From a societal perspective, the ICER was US$268 (₩299,255) per QALY (95% CI −US$2915 to US$3784). When using a willingness-to-pay threshold of US$22,367/QALY, the probability of hUCB being cost effectiveness compared with microfracture was 99% from the healthcare payer perspective and 100% from the societal perspective. Conclusions The study demonstrated that hUCB-MSC therapy was cost effective compared with microfracture when treating patients with knee OA. These findings should inform health policy decision makers about considerations for cost-effective therapy for treating knee OA to ultimately enhance population health.
