Hyperaldosteronism Screening and Findings From a Large Diverse Population With Resistant Hypertension Within an Integrated Health System.

INTRODUCTION: Hyperaldosteronism (HA) is a common cause of secondary hypertension and may contribute to resistant hypertension (RH). The authors sought to determine and characterize HA screening, positivity rates, and mineralocorticoid receptor antagonist (MRA) use among patients with RH. METHODS: A cross-sectional study was performed within Kaiser Permanente Southern California (7/1/2012-6/30/2017). Using contemporary criteria, RH was defined as blood pressure uncontrolled (≥ 130/80) on ≥ 3 medications or requiring ≥ 4 antihypertensive medications. The primary outcome was screening rate for HA defined as any aldosterone and plasma renin activity measurement. Secondary outcomes were HA screen positive rates and MRA use among all patients with RH. Multivariable logistic regression analysis was used to estimate odds ratio (with 95% confidence intervals) for factors associated with HA screening and for patients that screened positive. RESULTS: Among 102,480 patients identified as RH, 1977 (1.9%) were screened for HA and 727 (36.8%) screened positive for HA. MRA use was 6.5% among all patients with RH (22.5% among screened, 31.2% among screened positive). Black race, potassium < 4, bicarbonate > 29, chronic kidney disease, obstructive sleep apnea, and systolic blood pressure were associated with HA screening, but only Black race (1.55 [1.20-2.01]), potassium (1.82 [1.48-2.24]), bicarbonate levels (1.39 [1.10-1.75]), and diastolic blood pressure (1.15 [1.03-1.29]) were associated with positive screenings. CONCLUSION: The authors' findings demonstrate low screening rates for HA among patients with difficult-to-control hypertension yet a high positivity rate among those screened. Factors associated with screening did not always correlate with screening positive. Screening and targeted use of MRA may lead to improved blood pressure control and outcomes among patients with RH.

Creating a Safety Net Process to Improve Colon Cancer Diagnosis in Patients With Rectal Bleeding.

Background Failure to follow up on patients with rectal bleeding is common and may result in a delay in diagnosis of colorectal cancer or in missing high-risk adenomas. The authors' purpose was to create an electronic patient safety net for those diagnosed with rectal bleeding but who did not have colonoscopy to ensure proper detection of colonic abnormalities, including colon cancer. Methods In an integrated health delivery system serving < 4.6 million patients in Southern California, from 2014 to 2019, the authors electronically identified patients with rectal bleeding aged 45 to 80 years but with no recently documented colonoscopy. These cases were reviewed by a gastroenterologist to determine if colonoscopy was appropriate. The physician looked for known documentation as to the cause of rectal bleeding and verified no contraindications to the procedure; if indicated, testing was offered. Results Using the authors' safety net program, 1430 patients with rectal bleeding who needed and completed a colonoscopy were identified. Of those patients, 7.5% had an advanced adenoma or cancer, with a total of 20 cancers, and 34% had findings that warranted more frequent colonoscopy. Conclusions The authors designed a safety net system that was able to capture information on patients with rectal bleeding who had not had a colonoscopy and detected in 34% colonic pathology that would have otherwise gone undetected. The program did not require many resources to implement and had the ability to potentially prevent harm from reaching patients whose rectal bleeding did not get prompt workup. Other health systems and practices should consider implementing a similar system.

Potentially Harmful Medication Dispenses After a Fall or Hip Fracture: A Mixed Methods Study of a Commonly Used Quality Measure.

BACKGROUND: High-risk medication dispenses to patients with a prior fall or hip fracture represent a potentially dangerous disease-drug interaction among older adults. The research team quantified the prevalence, identified risk factors, and generated patient and provider insights into high-risk medication dispenses in a large, community-based integrated health system using a commonly used quality measure. METHODS: This was a mixed methods study with a convergent design combining a retrospective cohort study using electronic health record (EHR) data, individual interviews of primary care physicians, and a focus group of patient advisors. RESULTS: Of 113,809 patients ≥ 65 years with a fall/fracture in 2009-2015, 35.4% had a potentially harmful medication dispensed after their fall/fracture. Most medications were prescribed by primary care providers. Older age, male gender, and race/ethnicity other than non-Hispanic White were associated with a reduced risk of high-risk medication dispenses. Patients with a pre-fall/fracture medication dispense were substantially more likely to have a post-fall/fracture medication dispense (hazard ratio [HR] = 13.26, 95% confidence interval [CI] = 12.91-13.61). Both patients and providers noted that providers may be unaware of patient falls due to inconsistent assessments and patient reluctance to disclose falls. Providers also noted the lack of a standard location to document falls and limited decision support alerts within the EHR. CONCLUSION: High-risk medication dispenses are common among older patients with a history of falls/fractures. Future interventions should explore improved assessment and documentation of falls, decision support, clinician training strategies, patient educational resources, building trusting patient-clinician relationships to facilitate long-term medication discontinuation among persistent medication users, and a focus on fall prevention.

Concordance of End-of-Life Care With End-of-Life Wishes in an Integrated Health Care System.

Importance: There is widespread consensus on the challenges to meeting the end-of-life wishes of decedents in the US. However, there is broad but not always recognized success in meeting wishes among decedents 65 years and older. Objective: To assess how well end-of-life wishes of decedents 65 years and older are met in the last year of life. Design, Setting, and Participants: This quality improvement study involved 3 planned samples of family members or informants identified as the primary contact in the medical record of Kaiser Permanente Southern California decedents. The first sample was 715 decedents, 65 years or older, who died between April 1 and May 31, 2017. The second was a high-cost sample of 332 decedents, 65 years or older, who died between June 1, 2016, and May 31, 2017, and whose costs in the last year of life were in the top 10% of the costs of all decedents. The third was a lower-cost sample with 655 decedents whose costs were not in the top 10%. The survey was fielded between December 19, 2017, and February 8, 2018. Main Outcomes and Measures: Meeting end-of-life wishes, discussions with next of kin and physicians, types of discordant care, and perceptions of amount of care received. Results: Surveys were completed by 715 of the 2281 next of kin in the all-decedent sample (mean [SD] decedent age, 80.9 [8.9] years; 361 [50.5%] male) for a 31% response rate; in 332 of the 1339 next of kin in the high-cost sample (mean [SD] decedent age, 75.5 [7.1] years; 194 [48.4%] male) for a 25% response rate; and in 659 of 2058 in the lower-cost sample (mean [SD] decedent age, 81.6 [8.8] years) for a 32% response rate. Respondents noted that high percentages of decedents received treatment that was concordant with their desires: 601 (88.9%) had their wishes met, 39 (5.9%) received a treatment they did not want, and 554 (84.1%) filled out an advance directive. A total of 509 respondents (82.5%) believed the amount of care was the right amount. Those with the highest costs had their wishes met at lower rates than those with lower costs (250 [80.1%] vs 553 [89.6%]). Conclusions and Relevance: In this Kaiser Permanente Southern California cohort, a large proportion of decedents 65 years and older had end-of-life discussions and documentation, had their wishes met, and received the amount of care they thought appropriate.

Sex-Specific Trends in Acute Myocardial Infarction Within an Integrated Healthcare Network, 2000 Through 2014.

BACKGROUND: In recent decades, the rates of incident acute myocardial infarction (AMI) have declined in the United States, yet disparities by sex remain. In an integrated healthcare delivery system, we examined temporal trends in incident AMI among women and men. METHODS: We identified hospitalized AMI among members ≥35 years of age in Kaiser Permanente Southern California. The first hospitalization for AMI overall, and for ST-segment-elevation MI and non-ST-segment-elevation MI was identified by International Classification of Diseases, Ninth Revision, Clinical Modification primary discharge diagnosis codes in each calendar year from 2000 through 2014. Age- and sex-standardized incidence rates per 100 000 person-years were calculated by using direct adjustment to the 2010 US Census population. Average annual percent changes (AAPCs) and period percent changes were calculated, and trend tests were conducted using Poisson regression. RESULTS: We identified 45 331 AMI hospitalizations between 2000 and 2014. Age- and sex-standardized incidence rates of AMI declined from 322.4 (95% CI, 311.0-333.9) in 2000 to 174.6 (95% CI, 168.2-181.0) in 2014, representing an AAPC of -4.4% (95% CI, -4.2 to -4.6) and a period percent change of -46.6%. The AAPC for AMI in women was -4.6% (95% CI, -4.1 to -5.2) between 2000 and 2009 and declined to -2.3% (95% CI, -1.2 to -3.4) between 2010 and 2014. The AAPC for AMI in men was stable over the study period (-4.7% [95% CI, -4.4 to -4.9]). The AAPC for ST-segment-elevation MI hospitalization overall was -8.3% (95% CI, -8.0% to -8.6%).The AAPC in ST-segment-elevation MI changed among women in 2009 (2000-2009: -10.2% [95% CI, -9.3 to -11.1] and in 2010-2014: -5.2% [95% CI, -3.1 to -7.3]) while remaining stable among men (-8.0% [95% CI, -7.6 to -8.4]). The AAPC for non-ST-segment-elevation MI hospitalization was smaller than for ST-segment-elevation MI among both women and men (-1.9% [95% CI, -1.5 to -2.3] and -2.8% [95% CI, -2.5 to -3.2], respectively). CONCLUSIONS: These results suggest that the incidence of hospitalized AMI declined between 2000 and 2014; however, declines in AMI have slowed among women in comparison with men in recent years. Determining unmet care needs among women may reduce these sex-based AMI disparities.

Sub-acute hyponatraemia more than chronic hyponatraemia is associated with serious falls and hip fractures.

BACKGROUND: Falls and hip fractures among older people are associated with high morbidity and mortality. Hyponatraemia may be a risk for falls/hip fractures, but the effect of hyponatraemia duration is not well understood. AIMS: To evaluate individuals with periods of sub-acute and chronic hyponatraemia on subsequent risk for serious falls and/or hip fractures. METHODS: Retrospective cohort study in the period 1 January 1998 to 14 June 2016 within an integrated health system of individuals aged ≥55 years with ≥2 outpatient serum sodium measurements. Hyponatraemia was defined as sodium <135 mEq/L with sub-acute (<30 days) and chronic (≥30 days) analysed as a time-dependent exposure. Multivariable Cox proportional-hazards modelling was used to estimate hazard ratios (HR) for serious falls/hip fractures based on sodium category. RESULTS: Among 1 062 647 individuals totalling 9 762 305 sodium measurements, 96 096 serious falls/hip fracture events occurred. Incidence (per-1000-person-years) of serious falls/hip fractures were 11.5, 27.9 and 19.8 for normonatraemia, sub-acute and chronic hyponatraemia. Any hyponatraemia duration compared to normonatraemia had a serious falls/hip fractures HR (95%CI) of 1.18 (1.15, 1.22), with sub-acute and chronic hyponatraemia having HR of 1.38 (1.33, 1.42) and 0.91 (0.87, 0.95), respectively. Examined separately, the serious falls HR was 1.37 (1.32, 1.42) and 0.92 (0.88, 0.96) in sub-acute and chronic hyponatraemia, respectively. Hip fracture HR were 1.52 (1.42, 1.62) and 1.00 (0.92, 1.08) for sub-acute and chronic hyponatraemia, respectively, compared to normonatraemia. CONCLUSIONS: Our findings suggest that early/sub-acute hyponatraemia appears more vulnerable and associated with serious falls/hip fractures. Whether hyponatraemia is a marker of frailty or a modifiable risk factor for falls remains to be determined.

A Comparison of Online Physician Ratings and Internal Patient-Submitted Ratings from a Large Healthcare System.

BACKGROUND: Physician online ratings are ubiquitous and influential, but they also have their detractors. Given the lack of scientific survey methodology used in online ratings, some health systems have begun to publish their own internal patient-submitted ratings of physicians. OBJECTIVE: The purpose of this study was to compare online physician ratings with internal ratings from a large healthcare system. DESIGN: Retrospective cohort study comparing online ratings with internal ratings from a large healthcare system. SETTING: Kaiser Permanente, a large integrated healthcare delivery system. PARTICIPANTS: Physicians in the Southern California region of Kaiser Permanente, including all specialties with ambulatory clinic visits. MAIN MEASURES: The primary outcome measure was correlation between online physician ratings and internal ratings from the integrated healthcare delivery system. RESULTS: Of 5438 physicians who met inclusion and exclusion criteria, 4191 (77.1%) were rated both online and internally. The online ratings were based on a mean of 3.5 patient reviews, while the internal ratings were based on a mean of 119 survey returns. The overall correlation between the online and internal ratings was weak (Spearman's rho .23), but increased with the number of reviews used to formulate each online rating. CONCLUSIONS: Physician online ratings did not correlate well with internal ratings from a large integrated healthcare delivery system, although the correlation increased with the number of reviews used to formulate each online rating. Given that many consumers are not aware of the statistical issues associated with small sample sizes, we would recommend that online rating websites refrain from displaying a physician's rating until the sample size is sufficiently large (for example, at least 15 patient reviews). However, hospitals and health systems may be able to provide better information for patients by publishing the internal ratings of their physicians.

Follow-up of Abnormal Estimated GFR Results Within a Large Integrated Health Care Delivery System: A Mixed-Methods Study.

BACKGROUND: Timely follow-up of abnormal laboratory results is important for high-quality care. We sought to identify risk factors, facilitators, and barriers to timely follow-up of an abnormal estimated glomerular filtration rate (eGFR) for the diagnosis of chronic kidney disease. STUDY DESIGN: Mixed-methods study: retrospective electronic health record (EHR) analyses, physician interviews. SETTING & PARTICIPANTS: Large integrated health care delivery system. Quantitative analyses included 244,540 patients 21 years or older with incident abnormal eGFRs from January 1, 2010, to December 31, 2015, ordered by 7,164 providers. Qualitative analyses included 15 physician interviews. EXPOSURES: Patient-, physician-, and system-level factors. OUTCOME: Timely follow-up of incident abnormal eGFRs, defined as repeat eGFR obtained within 60 to 150 days, follow-up testing before 60 days that indicated normal kidney function, or diagnosis before 60 days of chronic kidney disease or kidney cancer. ANALYTICAL APPROACH: Multivariable robust Poisson regression models accounting for clustering within provider were used to estimate risk ratios (RRs) and 95% CIs for lack of timely follow-up. Team coding was used to identify themes from physician interviews. RESULTS: 58% of patients lacked timely follow-up of their incident abnormal eGFRs (ie, had a care gap). An abnormal creatinine result flag in the EHR was associated with better follow-up (RR for care gap, 0.65; 95% CI, 0.64-0.66). Patient online portal use and physician panel size were weakly associated with follow-up. Patients seen by providers behind on managing their EHR message box were at higher risk for care gaps. Physician interviews identified system-level (eg, panel size and assistance in managing laboratory results) and provider-level (eg, proficiency using EHR tools) factors that influence laboratory result management. LIMITATIONS: Unable to capture intentional delays in follow-up testing. CONCLUSIONS: Timely follow-up of abnormal results remains challenging in an EHR-based integrated health care delivery system. Strategies improving provider EHR message box management and leveraging health information technology (eg, flagging abnormal eGFR results), making organizational/staffing changes (eg, increasing the role of nurses in managing laboratory results), and boosting patient engagement through better patient portals may improve test follow-up.

End-Stage Renal Disease and Mortality Outcomes Across Different Glomerulonephropathies in a Large Diverse US Population.

OBJECTIVE: To compare renal function decline, incident end-stage renal disease (ESRD), and mortality among patients with 5 common glomerular diseases in a large diverse population. PATIENTS AND METHODS: A retrospective cohort study (between January 1, 2000, and December 31, 2011) of patients with glomerulonephropathy using the electronic health record of an integrated health system was performed. Estimated glomerular filtration rate (eGFR) change, incident ESRD, and mortality were compared among patients with biopsy-proven focal segmental glomerulosclerosis (FSGS), membranous glomerulonephritis (MN), minimal change disease (MCD), immunoglobulin A nephropathy (IgAN), and lupus nephritis (LN). Competing risk models were used to estimate hazard ratios for different glomerulonephropathies for incident ESRD, with mortality as a competing outcome after adjusting for potential confounders. RESULTS: Of the 2350 patients with glomerulonephropathy (208 patients [9%] younger than 18 years) with a mean follow-up of 4.5±3.6 years, 497 (21%) progressed to ESRD and 195 (8%) died before ESRD. The median eGFR decline was 1.0 mL/min per 1.73 m2 per year but varied across different glomerulonephropathies (P<.001). The highest ESRD incidence (per 100 person-years) was observed in FSGS 8.72 (95% CI, 3.93-16.72) followed by IgAN (4.54; 95% CI, 1.37-11.02), LN (2.38; 95% CI, 0.37-7.82), MN (2.15; 95% CI, 0.29-7.46), and MCD (1.67; 95% CI, 0.15-6.69). Compared with MCD, hazard ratios (95% CIs) for incident ESRD were 3.43 (2.32-5.08) and 2.35 (1.46-3.81), 1.28 (0.79-2.07), and 1.02 (0.62-1.68) for FSGS, IgAN, LN, and MN, respectively. No significant association between glomerulonephropathy types and mortality was detected (P=.24). CONCLUSION: Our findings from a real-world clinical environment revealed significant differences in eGFR decline and ESRD risk among patients with 5 glomerulonephropathies. These variations in presentation and outcomes warrant different management strategies and expectations.

End-Stage Renal Disease Outcomes among the Kaiser Permanente Southern California Creatinine Safety Program (Creatinine SureNet): Opportunities to Reflect and Improve.

OBJECTIVES: The Kaiser Permanente Southern California (KPSC) creatinine safety program (Creatinine SureNet) identifies and outreaches to thousands of people annually who may have had a missed diagnosis for chronic kidney disease (CKD). We sought to determine the value of this outpatient program and evaluate opportunities for improvement. METHODS: Longitudinal cohort study (February 2010 through December 2015) of KPSC members captured into the creatinine safety program who were characterized using demographics, laboratory results, and different estimations of glomerular filtration rate. Age- and sex-adjusted rates of end-stage renal disease (ESRD) were compared with those in the overall KPSC population. RESULTS: Among 12,394 individuals, 83 (0.7%) reached ESRD. The age- and sex-adjusted relative risk of ESRD was 2.7 times higher compared with the KPSC general population during the same period (94.7 vs 35.4 per 100,000 person-years; p < 0.001). Screening with the Chronic Kidney Disease Epidemiology Collaboration (vs Modification Diet in Renal Diseases) equation would capture 44% fewer individuals and have a higher predictive value for CKD. Of those who had repeated creatinine measurements, only 13% had a urine study performed (32% among patients with confirmed CKD). CONCLUSION: Our study found a higher incidence of ESRD among individuals captured into the KPSC creatinine safety program. If the Chronic Kidney Disease Epidemiology Collaboration equation were used, fewer people would have been captured while improving the accuracy for diagnosing CKD. Urine testing was low even among patients with confirmed CKD. Our findings demonstrate the importance of a creatinine safety net program in an integrated health system but also suggest opportunities to improve CKD care and screening.

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. RESULTS: Eighty-six percent (43) of the 50 decedents were initially diagnosed with stage III or IV CRC; two cases of appendiceal cancer were excluded. Thirty-one percent (15) of the remaining 48 cases presented with no history of screening; 15% (7) had documented iron deficiency anemia and abdominal pain or rectal bleeding; and 6% (3) had no follow-up colonoscopy after positive screening. Eleven (52%) of the 21 patients with initial stage II-III CRC received appropriate surveillance after curative surgery; 57% (12) developed metastases. Adjuvant chemotherapy was offered to 88% (14/16) of patients with stage III (node-positive) CRC; chemotherapy initiation was delayed in 6 patients. Missed opportunities for surgical oncology evaluation occurred among 61% (11/18) of patients with liver metastases at diagnosis. Failure to report clinically significant features on pathology occurred in 2 patients; they received appropriate treatment for other reasons. CONCLUSIONS: Improvement opportunities existed at multiple stages of care, including screening, evaluation of symp toms, timeliness of care, use of adjuvant chemotherapy, and surgical oncology practices.

Distribution of Biopsy-Proven Presumed Primary Glomerulonephropathies in 2000-2011 Among a Racially and Ethnically Diverse US Population.

BACKGROUND: The incidence and distribution of primary glomerulonephropathies vary throughout the world and by race and ethnicity. We sought to evaluate the distribution of primary glomerulonephropathies among a large racially and ethnically diverse population of the United States. STUDY DESIGN: Case series from January 1, 2000, through December 31, 2011. SETTING & PARTICIPANTS: Adults (aged ≥ 18 years) of an integrated health system who underwent native kidney biopsy and had kidney biopsy findings demonstrating focal segmental glomerulosclerosis (FSGS), membranous glomerulonephritis (MGN), minimal change disease (MCD), immunoglobulin A nephropathy (IgAN), and other. OUTCOMES: Rates and characteristics of the most common primary glomerulonephropathies overall and by race and ethnicity. RESULTS: 2,501 patients with primary glomerulonephropathy were identified, with a mean age 50.6 years, 45.7% women, 36.1% Hispanics, 31.2% non-Hispanic whites, 17.4% blacks, and 12.4% Asians. FSGS was the most common glomerulonephropathy (38.9%) across all race and ethnic groups, followed by MGN (12.7%), MCD (11.0%), IgAN (10.2%), and other (27.3%). The FSGS category had the greatest proportion of blacks, and patients with FSGS had the highest rate of poverty. IgAN was the second most common glomerulonephropathy among Asians (28.6%), whereas it was 1.2% among blacks. Patients with MGN presented with the highest proteinuria (protein excretion, 8.3g) whereas patients with FSGS had the highest creatinine levels (2.6mg/dL). Overall glomerulonephropathy rates increased annually in our 12-year observation period, driven by FSGS (2.7 cases/100,000) and IgAN (0.7 cases/100,000). MGN and MCD rates remained flat. LIMITATIONS: Missing data for urine albumin and sediment, indication bias in performing kidney biopsies, and inexact classification of primary versus secondary disease. CONCLUSIONS: Among a racially and ethnically diverse cohort from a single geographical area and similar environment, FSGS was the most common glomerulonephropathy, but there was variability of other glomerulonephropathies based on race and ethnicity.

Systemic implementation strategies to improve hypertension: the Kaiser Permanente Southern California experience.

The past decade has seen hypertension improving in the United States where control is approximately 50%. Kaiser Permanente has mirrored and exceeded these national advances in control. Integrated models of care such as Kaiser Permanente and the Veterans Administration health systems have demonstrated the greatest hypertension outcomes. We detail the story of Kaiser Permanente Southern California (KPSC) to illustrate the success that can be achieved with an integrated health system model that uses implementation, dissemination, and performance feedback approaches to chronic disease care. KPSC, with a large ethnically diverse population of more than 3.6 million, has used a stepwise approach to achieve control rates greater than 85% in those recognized with hypertension. This was accomplished through systemic implementations of specific strategies: (1) capturing hypertensive members into a hypertension registry; (2) standardization of blood pressure measurements; (3) drafting and disseminating an internal treatment algorithm that is evidence-based and is advocating of combination therapy; and (4) a multidisciplinary approach using medical assistants, nurses, and pharmacists as key stakeholders. The infrastructure, support, and involvement across all levels of the health system with rapid and continuous performance feedback have been pivotal in ensuring the follow-through and maintenance of these strategies. The KPSC hypertension program is continually evolving in these areas. With these high control rates and established infrastructure, they are positioned to take on different innovations and study models. Such potential projects are drafting strategies on resistant hypertension or addressing the concerns about overtreatment of hypertension.

Leveraging the electronic medical record to implement an abdominal aortic aneurysm screening program.

OBJECTIVE: Screening for abdominal aortic aneurysms (AAAs) reduces aneurysm-related mortality and has been recommended by the U.S. Preventive Services Task Force and American Heart Association since 2005. Medicare has covered a one-time screening ultrasound for new male enrollees with a familial or smoking history since 2007. Nevertheless, in the U.S., screening has remained underutilized. Review of patients with ruptured AAA in our system in 2007 showed the majority were undiagnosed, yet met U.S. Preventive Services Task Force and American Heart Association screening guidelines. To reduce the number of preventable AAA ruptures and deaths in our patients, we implemented an AAA screening program using our electronic medical record (EMR). This study describes the design, implementation, and early results of that screening program. METHODS: Between March 2012 and June 2013, men aged 65 to 75 years with any history of smoking were targeted for screening. Medical records were reviewed electronically to exclude patients with abdominal imaging studies within 10 years that would have diagnosed an AAA. Best practice alerts (BPA) were created in the EMR so when an appropriate patient is seen, office staff and providers are prompted to order an aortic ultrasound. AAA was defined as aortic diameter ≥3.0 cm or greater, and ultrasound reports contained a standard template providing guidance for patient management when an aneurysm was identified. Newly identified AAAs were triaged for vascular surgery consultation or follow-up with their primary physician. The number of eligible patients, unscreened patients, and AAAs identified were tabulated by our Regional Outpatient Safety Net Program. RESULTS: In a population of 3.6 million, 55,610 patients initially met screening criteria, and 26,837 (48.26%) were excluded from the BPA because of prior abdominal imaging studies. After 15 months, there were 68,164 patients who met screening criteria, 54,356 (79.74%) of whom had undergone an abdominal imaging study. Thus, 27,519 patients underwent an imaging study after the BPA was activated. During the study period, 731 new AAAs were diagnosed, 165 over 4.0 cm in diameter. Screening rates have increased at all medical centers where the BPA was activated, and the percentage of unscreened patients has been reduced from 51.74% to 20.26% system-wide. CONCLUSIONS: In an integrated health care system using an EMR, AAA screening can be implemented with a dramatic reduction in unscreened patients. Further analysis is required to assess the impact of the screening program on AAA rupture rate and cost-effectiveness in our system.

What does professionalism mean to the physician?

Professionalism, which is a core competency for physicians, can be described as a spectrum of behaviors and may have a significant impact on the problems in today's changing health care climate. In this article, we discuss the meaning of professionalism and its role in the Southern California Permanente Medical Group (SCPMG) and consider how it may be applied to integrated care delivery systems such as Kaiser Permanente. To understand professionalism, one must consider Stern's definition, which consists of four principles: excellence, humanism, accountability, and altruism. SCPMG has taken three of these principles-excellence, accountability, and altruism-and divided the fourth, humanism, into another three principles similar to those identified by the University of California Los Angeles Task Force on Professionalism: humanitarianism, respect for others, and honor and integrity. SCPMG has a rich history and culture of promoting clinical excellence and professionalism, as evidenced by the programs and initiatives described throughout this article. Indeed, the SCPMG experience validates professionalism as a core physician competency comprising a set of behaviors that are continually refined.
