Recruiting primary care practices for practice-based research: a case study of a group-randomized study (TRANSLATE CKD) recruitment process.

Background: We assessed the challenging process of recruiting primary care practices in a practice-based research study. Methods: In this descriptive case study of recruitment data collected for a large practice-based study (TRANSLATE CKD), 48 single or multiple-site health care organizations in the USA with a total of 114 practices were invited to participate. We collected quantitative and qualitative measures of recruitment process and outcomes for the first 25 practices recruited. Information about 13 additional practices is not provided due to staff transitions and limited data collection resources. Results: Initial outreach was made to 114 practices (from 48 organizations, 41% small); 52 (45%) practices responded with interest. Practices enrolled in the study (n = 25) represented 22% of the total outreach number, or 48% of those initially interested. Average time to enroll was 71 calendar days (range 11-107). There was no difference in the number of days practices remained under recruitment, based on enrolled versus not enrolled (44.8 ± 30.4 versus 46.8 ± 25.4 days, P = 0.86) or by the organization size, i.e. large versus small (defined by having ≤4 distinct practices; 52 ± 23.6 versus 43.6 ± 27.8 days; P = 0.46). The most common recruitment barriers were administrative, e.g. lack of perceived direct organizational benefit, and were more prominent among large organizations. Conclusions: Despite the general belief that the research topic, invitation method, and interest in research may facilitate practice recruitment, our results suggest that most of the recruitment challenges represent managerial challenges. Future research projects may need to consider relevant methodologies from businesses administration and marketing fields.

Perspectives on Smoking Cessation in Northern Appalachia.

This study applies qualitative research methods to explore perspectives on cessation among smokers/former smokers recruited from an area of Northern Appalachia. Six focus groups, stratified by age group (18-39 years old and 40 years and older), were conducted among participants (n = 54) recruited from community settings. Participants described varied interest in and challenges with quitting smoking. Smokers 40 years and older more readily endorsed the health risks of smoking and had greater interest in quitting assistance. Participants expressed frustration with the US government for allowing a harmful product (e.g., cigarettes) to be promoted with minimal regulation. Use of social media was robust among both age groups; participants expressed limited interest in various social media/technology platforms for promoting smoking cessation. Findings from this understudied area of northern Appalachia reflect the heterogeneity of this region and contribute novel information about the beliefs, attitudes, and experiences of current and formers smokers with regard to cessation.

KDOQI US commentary on the 2012 KDIGO clinical practice guideline for the evaluation and management of CKD.

The National Kidney Foundation-Kidney Disease Outcomes Quality Initiative (NKF-KDOQI) guideline for evaluation, classification, and stratification of chronic kidney disease (CKD) was published in 2002. The KDOQI guideline was well accepted by the medical and public health communities, but concerns and criticisms arose as new evidence became available since the publication of the original guidelines. KDIGO (Kidney Disease: Improving Global Outcomes) recently published an updated guideline to clarify the definition and classification of CKD and to update recommendations for the evaluation and management of individuals with CKD based on new evidence published since 2002. The primary recommendations were to retain the current definition of CKD based on decreased glomerular filtration rate or markers of kidney damage for 3 months or more and to include the cause of kidney disease and level of albuminuria, as well as level of glomerular filtration rate, for CKD classification. NKF-KDOQI convened a work group to write a commentary on the KDIGO guideline in order to assist US practitioners in interpreting the KDIGO guideline and determining its applicability within their own practices. Overall, the commentary work group agreed with most of the recommendations contained in the KDIGO guidelines, particularly the recommendations regarding the definition and classification of CKD. However, there were some concerns about incorporating the cause of disease into CKD classification, in addition to certain recommendations for evaluation and management.

Assessing the delivery of cessation services to smokers in urban, safety-net clinics.

Inequities in smoking behaviors continue to exist with higher rates among persons with limited formal education and for those living below the poverty level. This report describes the scope of tobacco cessation services delivered to low socio-economic status (SES) patients in several primary care medical offices, considered as "safety-net" sources of health care. Using a cross-sectional design, a random sample of records were reviewed for 922 smokers from 4 medical offices. The primary outcome variable was the delivery of smoking cessation services as documented in medical records; information on patient demographics and number of visits during the past 12 months was also abstracted. Smoking status was assessed during the last office visit for 65 % of smokers, 59 % were advised to quit, readiness to quit was assessed for 24 %, 2 % indicated a willingness to quit within the next 30 days and a quit date was established for 1 %. Among smokers not yet ready to quit, few were counseled on the "5 R's" (Relevance, Risks, Rewards, Roadblocks, Repetition). These results expand our understanding of the unfortunately limited scope of cessation services delivered to persons seen in safety-net medical offices and call attention to the need to redouble efforts to more effectively address smoking cessation among diverse, low SES patients served by safety-net primary care clinics.

Perceptions and use of the national kidney foundation KDOQI guidelines: a survey of U.S. renal healthcare providers.

BACKGROUND: The National Kidney Foundation (NKF) Kidney Disease Outcomes Quality Initiative (KDOQI) developed guidelines to care for patients with chronic kidney disease (CKD). While these are disseminated through the NKF's website and publications, the guidelines' usage remains suboptimal. The KDOQI Educational Committee was formed to identify barriers to guideline implementation, determine provider and patient educational needs and develop tools to improve care of patients with CKD. METHODS: An online survey was conducted from May to September 2010 to evaluate renal providers' familiarity, current use of and attitudes toward the guidelines and tools to implement the guidelines. RESULTS: Most responders reported using the guidelines often and felt that they could be easily implemented into clinical practice; however, approximately one-half identified at least one barrier. Physicians and physician extenders most commonly cited the lack of evidence supporting KDOQI guidelines while allied health professionals most commonly listed patient non-adherence, unrealistic guideline goals and provider time-constraints. Providers thought that the guidelines included too much detail and identified the lack of a quick resource as a barrier to clinical implementation. Most were unaware of the Clinical Action Plans. CONCLUSIONS: Perceived barriers differed between renal clinicians and allied health professionals; educational and implementation tools tailored for different providers are needed.

Fistula first breakthrough initiative: targeting catheter last in fistula first.

An arteriovenous fistula (AVF) is the optimal vascular access for hemodialysis (HD), because it is associated with prolonged survival, fewer infections, lower hospitalization rates, and reduced costs. The AVF First breakthrough initiative (FFBI) has made dramatic progress, effectively promoting the increase in the national AVF prevalence since the program's inception from 32% in May 2003 to nearly 60% in 2011. Central venous catheter (CVC) use has stabilized and recently decreased slightly for prevalent patients (treated more than 90 days), while CVC usage in the first 90 days remains unacceptably high at nearly 80%. This high prevalence of CVC utilization suggests important specific improvement goals for FFBI. In addition to the current 66% AVF goal, the initiative should include specific CVC usage target(s), based on the KDOQI goal of less than 10% in patients undergoing HD for more than 90 days, and a substantially improved initial target from the current CVC proportion. These specific CVC targets would be disseminated through the ESRD networks to individual dialysis facilities, further emphasizing CVC avoidance in the transition from advanced CKD to chronic kidney failure, while continuing to decrease CVC by prompt conversion of CVC-based hemodialysis patients to permanent vascular access, utilizing an AVF whenever feasible.

Practices, perceptions, and concerns of primary care physicians about opioid dependence associated with the treatment of chronic pain.

When prescribing opioids to treat chronic pain, physicians face the dilemma of balancing effective pain management while avoiding iatrogenic opioid addiction. Through mailed surveys, the current study assessed concerns, perceptions, and practices of primary care physicians related to this dilemma. Of the 35 (43%) physicians that replied, 32 (91.4%) reported to prescribe opioids for pain. Twenty-six (81.3%) physicians mentioned that "legitimate pain" was the main reason why most patients who are opioid dependent begin using opioids. Most physicians (71.5%) rated their knowledge/comfort of treatment/management of opioid dependence as being low. Although these physicians believed training is essential to learning about the risks involved with chronic pain and opioid dependence, many of these physicians evaluated their own medical training in these areas as unsatisfactory. Training programs may better equip primary care physicians when addressing the treatment of chronic pain and addiction to opioids.

High prevalence of undetected vitamin D deficiency in an urban minority primary care practice.

OBJECTIVES: To assess the prevalence of vitamin D deficiency among patients in an inner-city practice with a large African American population, and to evaluate the efficacy of vitamin D replacement as part of routine care. METHODS: A chart review was undertaken to identify patients aged 18 years and more with at least one 25-hydroxyvitamin D level. When patients were found to be deficient (vitamin D < 20) they were placed on 50000 units ergocalciferol monthly or over-the-counter calcium supplements with vitamin D. Descriptive statistics were used to calculate the prevalence rate, and paired t tests were used to compare the vitamin D levels pre and post treatment. RESULTS: A total of 369 (65%) out of 570 patients were found to be vitamin D deficient, and 253 were treated with ergocalciferol or vitamin D supplements. For patients deficient at baseline and treated with vitamin D supplementation (n = 253), significant differences were found between baseline and follow-up vitamin D levels (t(1,120) = 11.56, p < .001). Among 253 patients deficient at baseline and treated, 201 were corrected with oral vitamin D (79%), leaving 52 patients (21%) deficient after vitamin D supplementation. CONCLUSIONS: The results of this study show that there is a very high prevalence of vitamin D deficiency in an urban, mostly African American population. This can be readily improved with the addition of oral vitamin D. The study also suggests that routine vitamin D screening may be helpful for the detection and treatment of vitamin D deficiency, especially in urban minority populations.

Effect of 2 Clinical Decision Support Strategies on Chronic Kidney Disease Outcomes in Primary Care: A Cluster Randomized Trial.

Importance: Information is needed about optimal strategies to improve evidence-based treatment of chronic kidney disease (CKD) in primary care. Objective: To determine whether a multimodal intervention delays annualized loss of estimated glomerular filtration rate (eGFR) in stages 3 and 4 CKD. Design, Setting, and Participants: This pragmatic cluster randomized clinical trial enrolled 42 primary care practices located in nonhospital settings with electronic health record systems. Practices were recruited through the American Academy of Family Physicians National Research Network. The study was conducted January 2013 through January 2016. Interventions: Practices were randomized at the organization level to either the clinical decision support (CDS) plus practice facilitation (PF) group (n = 25) or CDS group (n = 17) using covariate constrained randomization. Both groups received point-of-care CDS to prompt screening, diagnosis, and treatment of CKD; the intervention group also received PF based on the 9-point TRANSLATE model (target, use point-of-care reminder systems, get administrative buy-in, network information systems using registries, site coordination, local physician champion, audit and feedback, team approach, and education). Main Outcomes and Measures: The primary outcome measure was eGFR over time. Secondary outcome measures were systolic blood pressure over time, change in hemoglobin A1c (HbA1c) over time, avoidance of nonsteroidal anti-inflammatory medications, use of angiotensin converting enzyme inhibitor or angiotensin-renin blocker medication, early recognition and diagnosis of CKD, blood pressure control, and smoking cessation. Results: In this cluster randomized trial of 30 primary care practices comprising 6699 patients, there were 1685 patients in the control group (10 practices) and 5014 patients in the intervention group (20 practices). The final sample of practices differed from the original set of randomized practices owing to dropout. Patients in the practices were similar at baseline for age (mean [SD], 71.3 [9.6] years), sex (2716 male [40.5%]), and eGFR. There was a significant difference in eGFR slopes for patients in the intervention vs control group practices. The mean (SE) annualized loss of eGFR was 0.95 (0.19) in the control group in propensity-adjusted longitudinal analyses and 0.01 (0.12) in the intervention group (mean [SE] difference in slopes, 0.93 [0.23]; P < .001). Among patients with HbA1c measures, slopes differed significantly for patients in intervention vs control practices, with a mean (SE) annualized increase of 0.14 (0.03) in HbA1c for patients in control practices and a mean (SE) decline of 0.009 (0.02) for patients in intervention practices. There was a significant difference in HbA1c slopes for patients in the intervention compared with control group practices (control vs intervention, -0.14; P < .001), but no difference in the other secondary outcomes. Conclusions and Relevance: A multimodal intervention in primary care, based on the TRANSLATE model, slowed annualized loss of eGFR. This study had several important strengths, weaknesses, and lessons learned regarding the implementation of pragmatic interventions in primary care to improve CKD outcomes.

Meaningful use's benefits and burdens for US family physicians.

Objective: The federal meaningful use (MU) program was aimed at improving adoption and use of electronic health records, but practicing physicians have criticized it. This study was aimed at quantifying the benefits (ie, usefulness) and burdens (ie, workload) of the MU program for practicing family physicians. Materials and Methods: An interdisciplinary national panel of experts (physicians and engineers) identified the work associated with MU criteria during patient encounters. They conducted a national survey to assess each criterion's level of patient benefit and compliance burden. Results: In 2015, 480 US family physicians responded to the survey. Their demographics were comparable to US norms. Eighteen of 31 MU criteria were perceived as useful for more than half of patient encounters, with 13 of those being useful for more than two-thirds. Thirteen criteria were useful for less than half of patient encounters. Four useful criteria were reported as having a high compliance burden. Discussion: There was high variability in physicians' perceived benefits and burdens of MU criteria. MU Stage 1 criteria, which are more related to basic/routine care, were perceived as beneficial by most physicians. Stage 2 criteria, which are more related to complex and population care, were perceived as less beneficial and more burdensome to comply with. Conclusion: MU was discontinued, but the merit-based incentive payment system within the Medicare Access and CHIP Reauthorization Act of 2015 adopted its criteria. For many physicians, MU created a significant practice burden without clear benefits to patient care. This study suggests that policymakers should not assess MU in aggregate, but as individual criteria for open discussion.

Facilitating quality improvement in physician management of comorbid chronic disease in an urban minority practice.

CONTEXT: Increasing numbers of patients with multiple chronic conditions present in the primary care setting and pose a challenge to physicians who must cope with competing demands while adhering to clinical practice guidelines. PURPOSE: We tested a chart audit tool to assess how physicians are managing patients with multiple comorbidities in an inner-city family medicine practice serving minority patients. METHODS: We developed an evidence-based comorbidity chart audit tool that captures the number of diagnosed, coexisting general medical conditions and adherence to key clinical practice guidelines for each condition. A randomized chart audit was undertaken, with one in every five charts selected, yielding a total of 314 patient charts. FINDINGS: The majority of patients (59%) had > or = 2 comorbid chronic conditions, and 32% had > or = 3 comorbid chronic conditions. The highest overall adherence to guidelines was for chronic obstructive pulmonary disease (90%) and asthma (80%), followed by congestive heart failure (75%) and coronary artery disease (58%). For all other conditions, overall adherence to guidelines was < or = 50%. CONCLUSIONS: The chart review tool identified inconsistencies in adherence to guidelines across multiple diagnosed conditions, suggesting the importance of adopting a patient-centered approach to management as well as prevention.

A method for measuring intracellular free magnesium concentration in platelets using flow cytometry.

Magnesium is the fourth most abundant cation in the body and is involved in over 302 enzymatic reactions. Basic science research has implicated magnesium deficiency as a cause of insulin resistance which is related to hypertension, diabetes, hyperlipidemia and increased cardiovascular risk. Research in magnesium deficiency states has been hindered because magnesium is an intracellular ion and difficult to measure. Our goal was to develop a reproducible assay to measure intracellular magnesium in platelets. Healthy volunteers agreed to have blood drawn for magnesium measurement. Platelet rich plasma was harvested from a venipuncture specimen and run through the flow cytometer. A standard titer curve using known increasing concentrations of magnesium chloride was created for each specimen, and then with the other half the specimen was run to measure the true intracellular free magnesium concentration. 15 adults agreed to volunteer for this experiment. All standard titer curves for all specimens had a correlation of > 0.99. The mean concentration of intracellular free magnesium was 450.05 microM with a range of 203.68 microM to 673.50 microM. Intracellular free magnesium can reliably and reproducibly be measured in platelets using Mag Green fluorescent dye and flow cytometry. This should advance our ability to study magnesium deficient states.

Extracting Deep Phenotypes for Chronic Kidney Disease Using Electronic Health Records.

INTRODUCTION: As chronic kidney disease (CKD) is among the most prevalent chronic diseases in the world with various rate of progression among patients, identifying its phenotypic subtypes is important for improving risk stratification and providing more targeted therapy and specific treatments for patients having different trajectories of the disease progression. PROBLEM DEFINITION AND DATA: The rapid growth and adoption of electronic health records (EHR) technology has created a unique opportunity to leverage the abundant clinical data, available as EHRs, to find meaningful phenotypic subtypes for CKD. In this study, we focus on extracting disease severity profiles for CKD while accounting for other confounding factors. PROBABILISTIC SUBTYPING MODEL: We employ a probabilistic model to identify precise phenotypes from EHR data of patients who have chronic kidney disease. Using this model, patient's eGFR trajectory is decomposed as a combination of four different components including disease subtype effect, covariate effect, individual long-term effect and individual short-term effect. EXPERIMENTAL RESULTS: The discovered disease subtypes obtained by Probabilistic Subtyping Model for CKD are presented and their clinical relevance is analyzed. DISCUSSION: Several clinical health markers that were found associated with disease subtypes are presented with suggestion for further investigation on their use as risk predictors. Several assumptions in the study are also clarified and discussed. CONCLUSION: The large dataset of EHRs can be used to identify deep phenotypes retrospectively. Directions for further expansion of the model are also discussed.

Insuring the uninsured: A student-run initiative to improve access to care in an urban community.

CONTEXT: There are 44 million uninsured Americans. Lack of insurance creates a major barrier for the poor and near poor to get adequate medical attention. A portion of these are eligible for insurance and either do not know they are eligible or have difficulty navigating the application process. OBJECTIVE: To evaluate the success of University at Buffalo medical students at a free clinic in helping patients enroll in government-sponsored insurance plans. DESIGN: Observational study SETTING: The Lighthouse Free Medical Clinic--a student-run free clinic operating in an urban minority Buffalo, NY neighborhood. PATIENTS: Five-hundred-seventy-nine inner-city, low-socioeconomic-status patients age <65. INTERVENTION: All patients are screened, and those eligible are encouraged and assisted in completing insurance applications. OUTCOME MEASURES: Primary outcome is the percentage of patients who completed the application process. RESULTS: Five-hundred-seventy-nine patients were seen from October 2003 through October 2004; 319 (55%) were uninsured. Fifty-nine (26%) of those uninsured were found to be eligible for insurance. Fifty-seven applications were initiated, and 23 (40%) were completed and accepted. CONCLUSIONS: There are a significant number of people using the free clinic who are eligible for insurance. The number-one reason adults were ineligible was household income exceeding the state limit. Success of this project provides support for the use of medical student volunteers to assist in insurance application completion in community settings.

A Practice Facilitation and Academic Detailing Intervention Can Improve Cancer Screening Rates in Primary Care Safety Net Clinics.

BACKGROUND: Despite the current evidence of preventive screening effectiveness, rates of breast, cervical, and colorectal cancer in the United States fall below national targets. We evaluated the efficacy and feasibility of combining practice facilitation and academic detailing quality improvement (QI) strategies to help primary care practices increase breast, cervical, and colorectal cancer screening among patients. METHODS: Practices received a 1-hour academic detailing session addressing current cancer screening guidelines and best practices, followed by 6 months of practice facilitation to implement evidence-based interventions aimed at increasing patient screening. One-way repeated measures analysis of variance compared screening rates before and after the intervention, provider surveys, and TRANSLATE model scores. Qualitative data were gathered via participant focus groups and interviews. RESULTS: Twenty-three practices enrolled in the project: 4 federally qualified health centers, 10 practices affiliated with larger health systems, 4 physician-owned practices, 4 university hospital clinics, and 1 nonprofit clinic. Average screening rates for breast cancer increased by 13% (P = .001), and rates for colorectal cancer increased by 5.6% (P = .001). Practices implemented a mix of electronic health record data cleaning workflows, provider audits and feedback, reminder systems streamlining, and patient education and outreach interventions. Practice facilitators assisted practices in tailoring interventions to practice-specific priorities and constraints and in connecting with community resources. Practices with resource constraints benefited from the engagement of all levels of staff in the quality improvement processes and from team-based adaptations to office workflows and policies. Many practices aligned quality improvement interventions in this project with patient-centered medical home and other regulatory reporting targets. CONCLUSIONS: Combining practice facilitation and academic detailing is 1 method through which primary care practices can achieve systems-level changes to better manage patient population health.

Correlates of obesity among patients attending an urban family medical center.

Urban populations face unique health challenges. We used data from a cross-sectional comprehensive health risk assessment survey conducted at an urban family medicine center to explore demographic and clinical correlates of obesity among 923 adults ages 20-64 years. Based on univariate analyses, there were no significant differences for body mass index (BMI) categories or health status ratings by racial group. A logistic model revealed that obese respondents (BMI >30.0) were significantly less likely to be female, white and to report a body image of overweight. Overall, just 25% of persons with a BMI of >30 classified themselves as being overweight. A second logistic model revealed that respondents reporting a body image of overweight were significantly more likely to be age 50-64 years, female, white and to report their health as good or fair/poor, which may reflect differing cultural and social beliefs of how individuals perceive their weight. This misperception between calculated BMI and reported body image in this urban population may serve to moderate attempts to address weight control as a health issue.

The Effect of Motivational Interviewing on Prescription Opioid Adherence Among Older Adults With Chronic Pain.

PURPOSE: To test the effect of office-based motivational interviewing (MI) on prescription opioid adherence in older adults with chronic pain. DESIGN AND METHODS: Pre- and post-design was used. Thirty chronic pain patients participated in a 4-week MI in two outpatient settings. FINDINGS: Participants demonstrated a significantly reduced risk of prescription opioid misuse, decreased substance use, increased self-efficacy, increased motivation to change, and decreased depression at both the post-test and 1-month follow-up. PRACTICE IMPLICATION: MI can be effectively delivered in outpatient settings for older adults who are at risk for opioid misuse. Clinicians could incorporate MI techniques to enhance prescription opioid adherence.
