Multifaceted interventions improve medication adherence and reduce acute hospitalization rates in medicaid patients prescribed asthma controllers.

OBJECTIVE: To measure the effectiveness of managed care-led interventions in Medicaid subjects with asthma on medication adherence and acute hospitalization in Pennsylvania. METHODS: A total of 3589 members (age range, 5-64 years) served by two Pennsylvania-based Medicaid managed care plans (southeastern Pennsylvania [SEPA] and Lehigh-Capital/New West Pennsylvania [LCNWPA]) with low adherence rates (proportion of days covered [PDC]; 20%-67%) for asthma controller prescription fills in 2012 were guided through a care continuum by a comprehensive asthma strategy, consisting of adherence-improvement interventions (grouped as general intervention [GI] or personalized intervention [PI] for higher-risk subjects). Medication adherence and acute hospitalization rates (emergency department [ED] and inpatient [IP]) were compared at baseline versus one-year post-intervention using paired t-test or signed-rank tests. Repeated measures analysis of variances detected the interaction effect of time by intervention group after controlling for sociodemographic covariates. RESULTS: Member profiles in SEPA (n = 2 796) and LCNWPA (n = 793) were racially and ethnically distinct. Both cohorts experienced statistically significant improvements in mean PDC rate (+4.9% and +7.2%; p = 0.01 and p = 0.03, respectively), accompanied by significant reductions in ED visits (asthma-related: -23.0% and -17.5%, respectively; p < 0.01), and IP admissions (asthma-related: -37.1% and -40.0%, respectively; p < 0.01). The PI subcohorts showed significantly greater improvements in mean PDC versus GI subcohorts (p ≤ 0.04), whereas acute hospitalization rates were statistically comparable in the SEPA cohort, despite its greater asthma burden. CONCLUSIONS: Managed care-led interventions can effectively improve medication adherence and reduce acute hospitalizations in high-risk Medicaid populations.

More Than Health Care Services: North Carolina's Focus on Improving Whole-person Health and Patient Experience.

North Carolina's transformation to Medicaid managed care is projected to improve health outcomes for the state's Medicaid population and elevate patient experience by integrating the social determinants of health into the state's care model and aligning state, provider, and health plan goals. This will increase access to timely, localized care services for members.

Transmission of MDR MRSA between primates, their environment and personnel at a United States primate centre.

OBJECTIVES: MDR MRSA isolates cultured from primates, their facility and primate personnel from the Washington National Primate Research Center were characterized to determine whether they were epidemiologically related to each other and if they represented common local human-associated MRSA strains. METHODS: Human and primate nasal and composite environmental samples were collected, enriched and selected on medium supplemented with oxacillin and polymyxin B. Isolates were biochemically verified as Staphylococcus aureus and screened for the mecA gene. Selected isolates were characterized using SCCmec typing, MLST and WGS. RESULTS: Nasal cultures were performed on 596 primates and 105 (17.6%) were MRSA positive. Two of 79 (2.5%) personnel and two of 56 (3.6%) composite primate environmental facility samples were MRSA positive. Three MRSA isolates from primates, one MRSA from personnel, two environmental MRSA and one primate MSSA were ST188 and were the same strain type by conventional typing methods. ST188 isolates were related to a 2007 ST188 human isolate from Hong Kong. Both MRSA isolates from out-of-state primates had a novel MLST type, ST3268, and an unrelated group. All isolates carried ≥1 other antibiotic resistance gene(s), including tet(38), the only tet gene identified. CONCLUSIONS: ST188 is very rare in North America and has almost exclusively been identified in people from Pan-Asia, while ST3268 is a newly reported MRSA type. The data suggest that the primate MDR MRSA was unlikely to come from primate centre employees. Captive primates are likely to be an unappreciated source of MRSA.

Fish consumption and advisory awareness among the Philadelphia Asian community: a pilot study.

Difficulties in the risk communication of fish consumption arise from the concept that this consumption can have both harmful and beneficial effects. This is particularly an issue among populations for which seafood is a major dietary and cultural component. Fish advisories are an important tool in preventing overconsumption of fish that have elevated concentrations of toxic contaminants. The exploratory pilot study described in this article examined fish consumption patterns and knowledge of the potential health risks associated with overconsumption of mercury-contaminated fish within a limited (N = 34) sample of the Philadelphia Asian-American population. Study data were used to evaluate the efficacy of state-issued advisories designed to encourage safe levels of fish consumption within the study population. Results indicate that while advisory awareness levels among study participants were greater than previously observed in Asian-American populations, consumption levels remained high. The limited findings of the authors' study, in combination with existing evidence, suggest the need for the development of more effective methods of disseminating advisory information.

Postdischarge engagement decreased hospital readmissions in Medicaid populations.

OBJECTIVES: To investigate the effect of managed care organization (MCO)-implemented postdischarge engagement, supported by other broadly focused interventions, on 30-day hospital readmissions in 6 at-risk Medicaid populations. STUDY DESIGN: Prospective cohort study. METHODS: One-year follow-up analysis of member claims data was performed following an intervention period from January 1, 2014, to December 31, 2014. Postdischarge engagement, supported by additional MCO-initiated interventions, was implemented to reduce 30-day hospital readmissions in Medicaid members having 1 or more dominant chronic conditions. Hospital readmission rates were calculated at baseline and at 1 year post intervention. Bivariable and multivariable generalized estimating equation analysis was used to quantify the likelihood of hospital readmissions. RESULTS: Following implementation, postdischarge engagement rates increased significantly, whereas provider follow-up rates remained unchanged. Increased member engagement resulted in statistically significant reductions in weighted readmission rates enterprise-wide (-10.1%; P <.01) and in 3 of 6 MCOs (-3.9% to -15.8%; P ≤.05) in 2014. Compared with nonparticipants, members who were successfully reached for postdischarge engagement displayed a 33% decrease in 30-day readmissions enterprise-wide (adjusted odds ratio, 0.67; 95% CI, 0.62-0.73) and a comparable decrease (-23% to -39%) in 5 of the 6 MCOs. In this context, greater frequency of postdischarge engagement was associated with proportionally decreased likelihood of readmissions. CONCLUSIONS: Postdischarge engagement, against the backdrop of multifaceted MCO-implemented interventions, was associated with significantly reduced hospital readmissions in at-risk Medicaid subjects. Reduced likelihood of readmissions was observed at both the enterprise-wide and plan levels in a manner proportional to the frequency of engagement, a novel reported outcome for this population.

Assessment of Environmental Contamination with Pathogenic Bacteria at a Hospital Laundry Facility.

Little is known about exposure to pathogenic bacteria among industrial laundry workers who work with soiled clinical linen. To study worker exposures, an assessment of surface contamination was performed at an industrial laundry facility serving hospitals in Seattle, WA, USA. Surface swab samples (n = 240) from the environment were collected during four site visits at 3-month intervals. These samples were cultured for Clostridium difficile, methicillin-resistant Staphylococcus aureus (MRSA), and vancomycin-resistant enterococci (VRE). Voluntary participation of 23 employees consisted of nasal swabs for detection of MRSA, observations during work, and questionnaires. Contamination with all three pathogens was observed in both dirty (laundry handling prior to washing) and clean areas (subsequent to washing). The dirty area had higher odds of overall contamination (≥1 pathogen) than the clean area (odds ratio, OR = 18.0, 95% confidence interval 8.9-36.5, P < 0.001). The odds of contamination were high for each individual pathogen: C. difficile, OR = 15.5; MRSA, OR = 14.8; and VRE, OR = 12.6 (each, P < 0.001). The highest odds of finding surface contamination occurred in the primary and secondary sort areas where soiled linens were manually sorted by employees (OR = 63.0, P < 0.001). The study substantiates that the laundry facility environment can become contaminated by soiled linens. Workers who handle soiled linen may have a higher risk of exposure to C. difficile, MRSA, and VRE than those who handle clean linens. Improved protocols for prevention and reduction of environmental contamination were implemented because of this study.

Clostridium difficile environmental contamination within a clinical laundry facility in the USA.

Clostridium difficile is both a hospital and community-acquired pathogen. The current study determined if C. difficile could be cultured from clinical laundry facility surfaces. A total of 240 surface samples were collected from dirty areas (n = 120), which handle soiled clinical linens, and from clean areas (n = 120), which process and fold the clean linens, within the University of Washington Consolidated Laundry facility in 2015. Sampling was done four times over the course of 1 year. The dirty area was significantly more contaminated than the clean area (21% vs 2%, P < 0.001). Clostridium difficile isolates were genetically characterized using multilocus sequence typing and PCR for the detection of genes encoding toxin A and toxin B. The MLST types 1, 2, 3, 15, 26, 34, 35, 39, 42, 43, 44, 53, 63 and 284 were identified and have previously been found in both clinical and community settings. Toxin positive isolates were identified in both the dirty (n = 16/25) and clean areas (n = 2/2). Seasonal variation was observed with 40% of the 27 isolates cultured in April 2015. The study suggests that soiled clinical linens may be a source of C. difficile surface contamination.

Collaborative DTM reduces hospitalization and healthcare costs in patients with diabetes treated with polypharmacy.

OBJECTIVES: To evaluate the effects of a collaborative pharmacy benefits manager (PBM)/ health plan-administered drug therapy management (DTM) program on healthcare utilization and costs in patients with diabetes treated with polypharmacy. STUDY DESIGN: Retrospective quasi-experimental design with comparison group. METHODS: This DTM program was a collaborative effort between the PBM, PerformRx, and the care management departments of Keystone First (KF) and AmeriHealth Caritas Pennsylvania (ACP) care management departments, targeting patients with diabetes using >15 medications. Pharmacists reviewed member profiles and made evidencebased prescriber and patient interventions, working directly with prescribers and indirectly with members, via care managers. Care managers provided additional services not otherwise within the scope of DTM. The study group consisted of 954 DTM participants reviewed by a pharmacist between November 1, 2010, and July 31, 2011. The control group consisted of 810 matched DTM participants not reviewed by a pharmacist. RESULTS: Intervention acceptance rates for KF and ACP were 33% and 26%, respectively. The study group demonstrated lower inpatient admissions and emergency department utilization rates, although only the KF study group inpatient admission rate achieved statistical significance (76.4%; P = .0002). The study groups realized statistically significant total cost savings (pharmacy + medical) compared with their corresponding control groups (47.8% KF, P = .0039; 50.7% ACP, P = .0497) despite non-statistically significant increases in pharmacy costs. CONCLUSIONS: A collaborative pharmacist-driven DTM program with a care manager-executed patient outreach component results in reduced hospital utilization and significant healthcare cost savings.
