Successful expanded clinic network collaboration and patient tracing for retention in HIV care.

Background: There are more than 7,800 people living with human immunodeficiency virus (HIV) in Victoria, Australia. Crucial in maximising the individual and population level benefits from antiretroviral therapy (ART) is understanding how to achieve patient retention in care and the factors that drive it. This study was an expansion of a 2015 assessment of HIV-care retention in Victoria, which sought out to determine whether the inclusion of a broader range of HIV-healthcare sites would yield more accurate estimates of retention in HIV-care.

Assessing antibiotic prescribing in nurse practitioners: Applied cognitive task analysis.

Background: Prescribing antibiotics is a demanding and complex task where decision-making skills are of critical importance to minimize the risk of antimicrobial resistance. Despite its importance, little is known about the decision-making skills and cognitive strategies new Nurse Practitioners (NPs) use when prescribing antibiotics.

Objective: To identify the cognitive demands of antibiotic prescribing complexity and to explore the cognitive strategies that new NPs in New Zealand use when prescribing antibiotics.

What is an estimand & how does it relate to quantifying the effect of treatment on patient-reported quality of life outcomes in clinical trials?

Background: Published in 2019, a new addendum to the ICH E9 guideline presents the estimand framework as a systematic approach to ensure alignment among clinical trial objectives, trial execution/conduct, statistical analyses, and interpretation of results. The use of the estimand framework for describing clinical trial objectives has yet to be extensively considered in the context of patient-reported outcomes (PROs). We discuss the application of the estimand framework to PRO objectives when designing clinical trials in the future, with a focus on PRO outcomes in oncology trial settings as our example.

Why N95 Should Be the Standard for All COVID-19 Inpatient Care.

Guidelines differ in their guidance on the use of N95 respirators versus medical masks for frontline health care workers working with patients with COVID-19, particularly when aerosolized procedures are not involved. This article makes the case that the existing data are inconclusive regarding the comparative effectiveness of N95 versus medical masks and could be misinterpreted. The authors suggest a reevaluation of this evidence or acknowledgement of these deficiencies in the setting of guidelines.

Characteristics of Orofacial Clefting in Hawai'i.

Orofacial clefts are birth defects that require a multi-disciplinary approach for repair and ongoing management as there are often concomitant chronic health issues. Orofacial clefts can occur as an isolated finding, in combination with other anomalies, or as part of a genetic syndrome. When occurring as part of a genetic syndrome, the complexity of management increases and has lifelong implications for these individuals, their families, and their health care providers.

Using Literature Review and Structured Hybrid Electronic/ Manual Mortality Review to Identify System-Level Improvement Opportunities to Reduce Colorectal Cancer Mortality.

Background: Despite colorectal cancer (CRC) screening and survival rates exceeding national averages in the United States, Kaiser Permanente Southern California (KPSC) aimed to identify system-level improvement opportunities to further reduce mortality from CRC.

Methods: To examine modifiable factors contributing to CRC mortality, a structured hybrid electronic/manual mor- tality review was used to examine 50 randomly selected cases among 524 individuals aged 25-75 years diagnosed with stage II, III, or IV CRC after July 2008 who subsequently died. Physicians conducted chart reviews using a standardized data extraction tool based on evidence-based best practices.

E-Autopsy: Using Structured Hybrid Manual/Electronic Mortality Reviews to Identify Quality Improvement Opportunities.

Background: Mortality reviews are a foundation of inpatient quality improvement (QI), but low levels of harm among a random or sequential sample may not yield actionable improvement opportunities. To increase the efficiency of mortality reviews at identifying QI opportunities, Kaiser Permanente Southern California (KPSC) developed a condition-specific hybrid electronic/manual chart review called the "e-autopsy."

Methods: KPSC hospital deaths are filtered electronically by predetermined criteria.

The readmission reduction program of Kaiser Permanente Southern California-knowledge transfer and performance improvement.

In 2011, Kaiser Permanente Northwest Region (KPNW) won the Lawrence Patient Safety Award for its innovative work in reducing hospital readmission rates. In 2012, Kaiser Permanente Southern California (KPSC) won the Transfer Projects Lawrence Safety Award for the successful implementation of the KPNW Region's "transitional care" bundle to a Region that was almost 8 times the size of KPNW. The KPSC Transition in Care Program consists of 6 KPNW bundle elements and 2 additional bundle elements added by the KPSC team.

Health-Related Quality of Life, Treatment Satisfaction, Adherence and Persistence in β-Thalassemia and Myelodysplastic Syndrome Patients with Iron Overload Receiving Deferasirox: Results from the EPIC Clinical Trial.

Treatment of iron overload using deferoxamine (DFO) is associated with significant deficits in patients' health-related quality of life (HRQOL) and low treatment satisfaction. The current article presents patient-reported HRQOL, satisfaction, adherence, and persistence data from β-thalassemia (n = 274) and myelodysplastic syndrome (MDS) patients (n = 168) patients participating in the Evaluation of Patients' Iron Chelation with Exjade (EPIC) study (NCT00171821); a large-scale 1-year, phase IIIb study investigating the efficacy and safety of the once-daily oral iron chelator, deferasirox. HRQOL and satisfaction, adherence, and persistence to iron chelation therapy (ICT) data were collected at baseline and end of study using the Medical Outcomes Short-Form 36-item Health Survey (SF-36v2) and the Satisfaction with ICT Questionnaire (SICT).

Medical care costs associated with progression of diabetic nephropathy.

Objective: To estimate the direct medical costs of hypertensive patients with type 2 diabetes by the level of proteinuria and to evaluate the differences between patients whose nephropathy did and did not progress.

Research Design And Methods: We identified 7,758 patients with diabetes and hypertension who had a urine albumin-to-creatinine ratio (UACR) during 2001-2003 and at least one follow-up UACR 3-5 years later. Patients were followed for up to 8 years for progression of nephropathy, which was defined by increasing levels of proteinuria: normoalbuminuria (UACR < 30 mg/g), microalbuminuria (30-299 mg/g), macroalbuminuria (≥300 mg/g), and end-stage renal disease (dialysis or transplant).

Saving lives by studying deaths: using standardized mortality reviews to improve inpatient safety.

Background: Despite extensive ongoing quality improvement (QI) efforts, substantial variation existed in hospital standardized mortality ratios (HSMRs) across hospitals in Kaiser Permanente, an integrated health care delivery system. In 2008, Kaiser Permanente developed an efficient and effective method for investigating hospital-level mortality to identify patterns of potential harm.

Methods: The standardized multidisciplinary mortality review process incorporates the Institute for Healthcare Improvement Global Trigger Tools and 2x2 Mortality Matrix, elements of the United Kingdom's National Health Service (NHS) 3x2 matrix, and two groups of questions to "deep dive" into issues of preventable harm and the use of appropriate care settings.

Assessment of time to follow-up visits in newly-treated hypertensive patients using an electronic medical record database.

Objective: Use of electronic medical record (EMR) data for evaluating healthcare processes and outcomes is relatively new. Using EMR data, this study evaluated the time from antihypertensive initiation to the first follow-up office visit controlling for adverse events (AEs) and other factors that could influence follow-up timing. Findings were compared to treatment guidelines which recommend monthly follow-up in treatment naive patients until blood pressure (BP) levels are controlled.

Association between incidence of acute exacerbation and medication therapy in patients with COPD.

Background: As exacerbations of chronic obstructive pulmonary disease (COPD) significantly worsen patients' health status and increase disease-related mortality, greater control of exacerbations has important implications for improving patients' health and survival. The incremental benefits of pharmacologic therapies in preventing COPD exacerbations remain unclear. The objective of this observational study was to examine the risk of COPD-related exacerbations between groups of patients receiving inhaled corticosteroids (ICS), anticholinergics (AC), long-acting beta(2)-agonists (LABA), or fixed-dose combinations of ICS and LABA.

Cost-effectiveness of aliskiren in type 2 diabetes, hypertension, and albuminuria.

The Aliskiren in the Evaluation of Proteinuria in Diabetes (AVOID) trial demonstrated that adding aliskiren, an oral direct renin inhibitor, at a dosage of 300 mg/d to the highest approved dosage of losartan and optimal antihypertensive therapy reduces albuminuria over 6 mo among patients with type 2 diabetes, hypertension, and albuminuria. The cost-effectiveness of this therapy, however, is unknown. Here, we used a Markov model to project progression to ESRD, life years, quality-adjusted life years, and lifetime costs for aliskiren plus losartan versus losartan.

Medication Utilization Patterns and Hypertension-Related Expenditures among Patients Who Were Switched from Fixed-Dose To Free-Combination Antihypertensive Therapy.

Using a retrospective cohort study of medical and pharmacy claims data, we evaluated medication compliance, persistence, and hypertension-related expenditures among patients who were switched from fixed-dose combination (FDC) to free-combination (FC) antihypertensive therapy. An example of a fixed-dose combination product for hypertension would be a valsartan/HCT tablet, and a free-combination product would be a valsartan tablet plus a diuretic tablet.The 7,224 patients identified from January 2003 to December 2005 were matched, in a 1:1 ratio, by propensity scores to controls who remained on their FC antihypertensive medications.

Predictors of compliance with antihypertensive therapy in a high-risk medicaid population.

Objective: To identify predictors of compliance with antihypertensive combination therapy in a Medicaid population.

Methods: Retrospective medical and pharmacy claims data for Maryland Medicaid patients receiving angiotensin converting enzyme inhibitors (ACEls)/hydrochlorothiazides (HCTZs) or ACEl/calcium channel blockers as fixed-dose combinations or separate agents during the period of January 1, 2002 to December 31, 2004, were analyzed.

Inclusion: Continuously enrolled patients 18 years and older and at least one year of follow-up.

Predictors of fixed-dose combination antihypertensive drug therapy in a Medicaid population.

Physicians may prescribe hypertension combination therapy, either with fixed-dose combination therapy or with dual-agent component-based therapy. This study evaluated the predictors of hypertensive patients receiving either type of combination therapy. Our study was based on claims data from the Maryland Medicaid Managed Care Organizations.

Sex differences in ambulatory visits for chronic obstructive pulmonary disease, based on the National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey from 1995 to 2004.

Background: Chronic obstructive pulmonary disease (COPD) is a rapidly growing public health problem in the United States. It is unclear whether men and women differ in their utilization of ambulatory care or medications prescribed for COPD.

Objective: To evaluate sex-related trends in physician-office and out-patient department COPD visits from 1995 through 2004.

Host and microbiota factors that control Klebsiella pneumoniae mucosal colonization in mice.

Klebsiella pneumoniae is both an opportunistic pathogen and a commensal organism. We have previously reported that K. pneumoniae strain IA565 (KpIA565) is non-pathogenic in a murine model of acute pneumonia.

Identification of Klebsiella pneumoniae genes uniquely expressed in a strain virulent using a murine model of bacterial pneumonia.

Klebsiella pneumoniae is a gram-negative bacterium of significant clinical importance. This study examines the differential pulmonary host anti-bacterial responses towards two clinical isolates of K. pneumoniae.

Assessment of linkage and association of 13 genetic loci with bone mineral density.

Bone mineral density (BMD), an important risk factor for osteoporosis, is a complex trait likely affected by multiple genes. The linkage and/or association of 13 polymorphic loci of seven candidate genes (estrogen receptor alpha [ERalpha] and beta [ERbeta], calcium-sensing receptor, vitamin D receptor, collagen type 1alpha1, low-density lipoprotein [LDL] receptor-related protein 5 [LRPS], and transforming growth factor beta1) were evaluated in 177 southern Chinese pedigrees of 674 subjects, with each pedigree identified through a proband having a BMD Z score of -1.28 or less at the hip or spine.

Defective innate antibacterial host responses during murine Klebsiella pneumoniae bacteremia: tumor necrosis factor (TNF) receptor 1 deficiency versus therapy with anti-TNF-alpha.

Klebsiella pneumoniae is a leading cause of pneumonia due to gram-negative bacteria. A significant clinical complication of pulmonary infection with K. pneumoniae is peripheral blood dissemination, which results in a systemic infection coincident with the localized pulmonary infection.
