Hospitals vary in organisational culture, and the type of culture relates to the safety climate within the hospital. In combination with prior studies, these results suggest that a healthcare organisation's culture is a critical factor in the development of its patient safety climate and in the successful implementation of quality improvement initiatives.
Barriers remain in the hepatitis C virus (HCV) cascade of care (CoC), limiting the overall impact of direct acting antivirals. This study examines movement between the stages of the HCV CoC and identifies reasons why patients and specific patient populations fail to advance through care in a real world population. We performed a single-center, ambispective cohort study of patients receiving care in an outpatient infectious diseases clinic between October 2015 and September 2016. Patients were followed from treatment referral through sustained virologic response. Univariate and multivariate analyses were performed to identify factors related to completion of each step of the CoC. Of 187 patients meeting inclusion criteria, 120 (64%) completed an evaluation for HCV treatment, 119 (64%) were prescribed treatment, 114 (61%) were approved for treatment, 113 (60%) initiated treatment, 107 (57%) completed treatment, and 100 (53%) achieved a sustained virologic response. In univariate and multivariate analyses, patients with Medicaid insurance were less likely to complete an evaluation and were less likely to be approved for treatment. Treatment completion and SVR rates are much improved from historical CoC reports. However, linkage to care following referral continues to be a formidable challenge for the HCV CoC in the DAA era. Ongoing efforts should focus on linkage to care to capitalize on DAA treatment advances and improving access for patients with Medicaid insurance.
Background Most surgeons believe that graft choice for ACL reconstruction is an important factor related to outcome. Although graft choice may be limited in the revision setting based on previously used grafts, it is still felt to be important. Hypothesis The purpose of this study was to determine if revision ACL graft choice predicts outcomes related to sports function, activity level, OA symptoms, graft re-rupture, and reoperation at two years following revision reconstruction. We hypothesized that autograft use would result in increased sports function, increased activity level, and decreased OA symptoms (as measured by validated patient reported outcome instruments). Additionally, we hypothesized that autograft use would result in decreased graft failure and reoperation rate 2 years following revision ACL reconstruction. Study Design Prospective cohort study; Level of evidence, 2. Methods Revision ACL reconstruction patients were identified and prospectively enrolled by 83 surgeons over 52 sites. Data collected included baseline demographics, surgical technique and pathology, and a series of validated patient reported outcome instruments (IKDC, KOOS, WOMAC, and Marx activity rating score). Patients were followed up at 2 years, and asked to complete the identical set of outcome instruments. Incidence of additional surgery and reoperation due to graft failure were also recorded. Multivariate regression models were used to determine the predictors (risk factors) of IKDC, KOOS, WOMAC, Marx scores, graft re-rupture, and reoperation rate at 2 years following revision surgery. Results 1205 patients were successfully enrolled with 697 (58%) males. Median age was 26. In 88% this was their first revision. 341 (28%) were undergoing revision by the surgeon that had performed the previous reconstruction. 583 (48%) underwent revision reconstruction utilizing an autograft, 590 (49%) allograft, and 32 (3%) both autograft and allograft. Median time since their last ACL reconstruction was 3.4 years. Questionnaire follow-up was obtained on 989 subjects (82%), while phone follow-up was obtained on 1112 subjects (92%). The IKDC, KOOS, and WOMAC scores (with the exception of the WOMAC stiffness subscale) all significantly improved at the two year follow-up time point (p<0.001). In contrast, the two year MARX activity scale demonstrated a significant decrease from the initial score at enrollment (p<0.001). Graft choice proved to be a significant predictor of 2 year IKDC scores (p=0.017). Specifically, the use of an autograft for revision reconstruction predicted improved score on the IKDC [p=0.045; Odds Ratio (OR) = 1.31; 95% confidence intervals (CI) = 1.01, 1.70]. The use of an autograft predicted an improved on the KOOS subscale Sports and Recreation (p=0.037; OR=1.33; 95% CI=1.02, 1.73). Use of an autograft also predicted improved scores on the KOOS subscale Quality of Life (QOL) (p=0.031; OR=1.33; 95% CI=1.03, 1.73). For the KOOS Symptoms and ADL subscales, graft choice did not predict outcome score. Graft choice als...
Background Medication non-adherence increases the risk of hospitalization and poor outcomes, particularly among patients with cardiovascular disease (CVD). Purpose To examine characteristics associated with medication non-adherence among adults hospitalized for CVD. Methods Patients in the Vanderbilt Inpatient Cohort Study who were admitted for acute coronary syndromes or heart failure completed validated assessments of self-reported medication adherence (the Adherence to Refills and Medications Scale [ARMS]), demographic characteristics, health literacy, numeracy, social support, depressive symptoms, and health competence. We modeled the independent predictors of non-adherence before hospitalization, standardizing estimated effects by each predictor’s interquartile range (IQR). Results Among 1967 patients studied, 70.7% indicated at least some degree of medication non-adherence leading up to their hospitalization. Adherence was significantly lower among patients with lower health literacy (0.18 point change in adherence score per IQR change in health literacy), lower numeracy (0.28), lower health competence (0.30), and more depressive symptoms (0.52), and those of younger age, non-White race, male gender, or less social support. Conclusions Medication non-adherence in the period before hospitalization is more prevalent among patients with lower health literacy, numeracy, or other intervenable psychosocial factors. Addressing these factors in a coordinated care model may reduce hospitalization rates.
BACKGROUND: Collaborative and toolkit approaches have gained traction for improving quality in health care. OBJECTIVE: To determine if a quality improvement virtual collaborative intervention would perform better than a toolkit‐only approach at preventing central line–associated bloodstream infections (CLABSIs) and ventilator‐associated pneumonias (VAPs). DESIGN AND SETTING: Cluster randomized trial with the Intensive Care Units (ICUs) of 60 hospitals assigned to the Toolkit (n=29) or Virtual Collaborative (n=31) group from January 2006 through September 2007. MEASUREMENT: CLABSI and VAP rates. Follow‐up survey on improvement interventions, toolkit utilization, and strategies for implementing improvement. RESULTS: A total of 83% of the Collaborative ICUs implemented all CLABSI interventions compared to 64% of those in the Toolkit group (P = 0.13), implemented daily catheter reviews more often (P = 0.04), and began this intervention sooner (P < 0.01). Eighty‐six percent of the Collaborative group implemented the VAP bundle compared to 64% of the Toolkit group (P = 0.06). The CLABSI rate was 2.42 infections per 1000 catheter days at baseline and 2.73 at 18 months (P = 0.59). The VAP rate was 3.97 per 1000 ventilator days at baseline and 4.61 at 18 months (P = 0.50). Neither group improved outcomes over time; there was no differential performance between the 2 groups for either CLABSI rates (P = 0.71) or VAP rates (P = 0.80). CONCLUSION: The intensive collaborative approach outpaced the simpler toolkit approach in changing processes of care, but neither approach improved outcomes. Incorporating quality improvement methods, such as ICU checklists, into routine care processes is complex, highly context‐dependent, and may take longer than 18 months to achieve. © Society of Hospital Medicine Journal of Hospital Medicine 2011
Background: Disease-modifying therapy (DMT) delays disease progression and improves quality of life for patients with multiple sclerosis (MS), but adherence to DMT is often suboptimal. Vanderbilt Specialty Pharmacy (VSP) embeds pharmacists within an outpatient MS clinic to provide medication management and address barriers to adherence. Objective: We evaluated rates and predictors of adherence to DMT among patients with MS at an integrated specialty pharmacy. Methods: We included patients with MS who filled ≥3 DMT prescriptions from VSP during the study period. Adherence was defined as medication possession ratio (MPR) or proportion of days covered (PDC) ≥0.8. Reasons for nonadherence were collected from pharmacy claims and electronic medical records. Results: The study included 653 patients. Average MPR and PDC were 0.93 and 0.94, respectively. Eighty-eight percent of patients achieved MPR ≥0.8; 89% achieved PDC ≥0.8. Using financial assistance and having $0 out-of-pocket cost were associated with higher odds of achieving MPR and PDC ≥0.8 ( P < .05). Of the 12% of patients who were nonadherent, most were unreachable for refills. Conclusions: Ensuring financial assistance and low out-of-pocket costs are associated with high adherence to DMT within an integrated specialty clinic, but more work is needed to address adherence in unreachable patients.
ObjectiveUnderstanding variations in size and pattern of development of angiotensin II (Ang II)-induced abdominal aortic aneurysms (AAA) may inform translational research strategies. Thus, we sought insight into the temporal evolution of AAA in apolipoprotein (apo)E−/− mice.ApproachA cohort of mice underwent a 4-week pump-mediated infusion of saline (n = 23) or 1500 ng/kg/min of Ang II (n = 85) and AAA development was tracked via in vivo ultrasound imaging. We adjusted for hemodynamic covariates in the regression models for AAA occurrence in relation to time.ResultsThe overall effect of time was statistically significant (p<0.001). Compared to day 7 of AngII infusion, there was no decrease in the log odds of AAA occurrence by day 14 (−0.234, p = 0.65), but compared to day 21 and 28, the log odds decreased by 9.07 (p<0.001) and 2.35 (p = 0.04), respectively. Hemodynamic parameters were not predictive of change in aortic diameter (Δ) (SBP, p = 0.66; DBP, p = 0.66). Mean total cholesterol (TC) was higher among mice with large versus small AAA (601 vs. 422 mg/ml, p<0.0001), and the difference was due to LDL. AngII exposure was associated with 0.43 mm (95% CI, 0.27 to 0.61, p<0.0001) increase in aortic diameter; and a 100 mg/dl increase in mean final cholesterol level was associated with a 12% (95% CI, 5.68 to 18.23, p<0.0001) increase in aortic diameter. Baseline cholesterol was not associated with change in aortic diameter (p = 0.86).ConclusionsThese are the first formal estimates of a consistent pattern of Ang II-induced AAA development. The odds of AAA occurrence diminish after the second week of Ang II infusion, and TC is independently associated with AAA size.
