BACKGROUND

Awareness of chronic kidney disease (CKD) is suboptimal among patients with CKD, perhaps due to poor readability of patient education materials (PEMs). We reviewed the suitability and readability of common PEMs that focused on 5 content areas: basics of CKD, risk factors for CKD development, risk factors for CKD progression, complications of CKD and self-management strategies to improve kidney health.

METHODS

Three reviewers (nephrologist, primary care physician, patient) used the Suitability Assessment of Materials to rate PEMs on message content/stimulation of learning, typography, visuals and layout and determined literacy level. Mean ratings were calculated for each PEM by content area and overall (superior = 70-100; adequate = 40-69; inadequate = <40). Linear regression was used to determine the impact of literacy level on mean rating.

RESULTS

We reviewed 69 PEMs from 19 organizations, divided into 113 content area sections. Most (79%) PEM sections were 'adequate' (mean rating, 58.3%). Inclusion of patient-centered content and opportunities for patient interaction were associated with 'superior' ratings. Mean ratings (SD) were similar across content areas: basics of CKD, 58.9% (9.1); risk factors for CKD development, 57.0% (12.3); risk factors for CKD progression, 58.5% (12.0); CKD complications, 62.3% (15.7), and self-management strategies, 62.2% (12.3). ≤6th grade literacy level (vs. >6th grade) was associated with an 11.7 point higher mean rating.

CONCLUSION

Most PEMs for kidney disease were adequate. Outstanding PEMs shared characteristics of patient centeredness, a low literacy level, and patient interaction. Providers should be aware of strengths and limitations of PEMs when educating their patients about CKD.

CONTEXT

We have reconceptualized advance care planning (ACP) as a multistep process focused on preparing patients with skills needed for communication and in-the-moment decision making.

OBJECTIVES

To operationalize this paradigm, we created an easy-to-use ACP website (prepareforyourcare.org) based on a theoretical framework of behavior change and pilot-tested its efficacy to engage older adults in ACP.

METHODS

At baseline and 1 week after viewing the PREPARE website, we assessed behavior change in ACP by using a validated survey that includes Process Measures (knowledge, contemplation, self-efficacy, and readiness, 5-point Likert scales) and Action Measures (yes/no whether an ACP behavior was completed). We also assigned participants into behavior change stages (i.e., precontemplation, contemplation, preparation, action, maintenance) and determined the percentage of participants who moved from precontemplation at baseline to higher stages at 1 week. We also assessed PREPARE ease-of-use (10-point scale, 10 being the easiest). Changes were assessed with Wilcoxon signed rank sum tests and McNemar's tests.

RESULTS

Mean age of the participants was 68.4 years (SD 6.6), and 65% were nonwhite. Behavior Change Process Measures average Likert scores increased from 3.1 (0.9) to 3.7 (0.7), P < 0.001. Action Measures did not change significantly. However, precontemplation significantly decreased for most actions (e.g., talking to doctor about desired medical care, 61% to 35%, P < 0.003), with a mean decrease of 21% (range, 16%-33%). PREPARE was rated a nine of ten (±1.9) for ease-of-use.

CONCLUSION

A new, patient-centered ACP website that focuses on preparing patients for communication and decision making significantly improves engagement in the process of ACP and behavior change. A clinical trial of PREPARE is currently underway.

OBJECTIVE

To explore the association between baseline life-space mobility and nursing home (NH) admission among community-dwelling older adults over 6 years.

METHODS

Using data from a prospective, observational cohort study consisting of a random sample of 1,000 Medicare beneficiaries ≥ 65 years of age stratified by race (African American and non-Hispanic White), sex, and rural/urban residence. Baseline life-space mobility was assessed during in-home interviews. Participants were contacted by telephone every 6 months to ascertain NH admissions, Life-Space Assessment (LSA) scores, and vital status (living or deceased). Using multivariate logistic regression, the significance and independence of the relationship of life-space mobility with NH admission were examined.

RESULTS

Over 6 years, the odds of NH admission increased 2% for every one point lower baseline life-space score independent of previously recognized risk factors.

DISCUSSION

The LSA may be a useful tool to identify older adults at risk of NH admission.

OBJECTIVE

With increasing oversight of postoperative outcomes with the Patient Protection and Affordable Care Act, the reduction of readmissions is necessary to avoid financial penalties. This article provides a multi-institutional, multivariate analysis of the pre- and postoperative patient factors associated with readmission after carotid endarterectomy (CEA).

METHODS

Using the National Surgical Quality Improvement Program from 2011, we considered 8456 patients. The primary outcome variable was 30-day unplanned readmission. Multiple logistic regression was used, and we controlled for preoperative demographic variables, comorbidities and clinical characteristics, and postoperative medical and surgical complications.

RESULTS

Patients with CEA had a 6.0% unplanned readmission rate. The most common comorbidities in the readmitted patients included hypertension, diabetes, and bleeding disorder. Risk-adjusted multiple regression indicated that preoperative bleeding disorder (odds ratio [OR] 1.62), diabetes (OR 1.46), history of a cerebrovascular accident/stroke (OR 1.46), and increasing age (OR 1.01) were statistically significant predictors for readmission. Postoperatively, surgical-site infection (OR 21.90), myocardial infarction (OR 10.35), sepsis/septic shock (OR 7.79), cerebrovascular accident/stroke (OR 6.58), pneumonia (OR 4.37), and urinary tract infection (OR 3.21) were associated with a greater rate of readmission.

CONCLUSIONS

Readmission after CEA occurs at a comparatively high rate. Preoperative bleeding disorders, diabetes, cerebrovascular accidents, and age and postoperative surgical-site infection, myocardial infarction, sepsis/septic shock, pneumonia, and cerebrovascular accident were associated with readmission. These findings may help guide the surgical management of patients and prevent costly readmissions.

RATIONALE, AIMS AND OBJECTIVES

To describe primary care providers' (PCP) attitudes about the impact of a mature, commercial electronic health records (EHR) on clinical practice in settings with experience using the system and to evaluate whether a provider's propensity to adopt new technologies is associated with more favourable perceptions.

METHOD

We surveyed PCPs in 11 practices affiliated with three health systems in Texas. Most practices had greater than 5 years of experience with the Epic EHR. The effect of early adopter of technology status was evaluated using logistic regression.

RESULTS

One hundred forty-six PCPs responded (70%). Most thought the EHR had a positive impact on routine tasks, such as prescription refills (94%), whereas fewer agreed for complex tasks, such as delivery of guideline-concordant care for chronic illnesses (51%). Two-thirds (62%) thought it interfered with eye contact with patients, and 40% reported that it interfered with in-visit communication. Early adopters of technology reported greater positive effects of the EHR, even after adjusting for age, ranging from 2% to 15% higher on satisfaction ratings.

CONCLUSION

PCPs practicing in settings with considerable experience using a common commercial EHR identified many positive effects, as well as two key areas for improvement - patient centredness and intelligent decision support. Providers with a propensity to adopt new technologies have more favourable perceptions of the EHR.

BACKGROUND

The pathogenic mechanisms underlying pulmonary arterial hypertension resulting from schistosomiasis, one of the most common causes of pulmonary hypertension worldwide, remain unknown. We hypothesized that transforming growth factor-β (TGF-β) signaling as a consequence of Th2 inflammation is critical for the pathogenesis of this disease.

METHODS AND RESULTS

Mice sensitized and subsequently challenged with Schistosoma mansoni eggs developed pulmonary hypertension associated with an increase in right ventricular systolic pressure, thickening of the pulmonary artery media, and right ventricular hypertrophy. Rho-kinase-dependent vasoconstriction accounted for ≈60% of the increase in right ventricular systolic pressure. The pulmonary vascular remodeling and pulmonary hypertension were dependent on increased TGF-β signaling, as pharmacological blockade of the TGF-β ligand and receptor, and mice lacking Smad3 were significantly protected from Schistosoma-induced pulmonary hypertension. Blockade of TGF-β signaling also led to a decrease in interleukin-4 and interleukin-13 concentrations, which drive the Th2 responses characteristic of schistosomiasis lung pathology. Lungs of patients with schistosomiasis-associated pulmonary arterial hypertension have evidence of TGF-β signaling in their remodeled pulmonary arteries.

CONCLUSION

Experimental S mansoni-induced pulmonary vascular disease relies on canonical TGF-β signaling.
