Abstract
Abstract Social needs, such as social isolation and food insecurity, are important individual-level social determinants of health, especially for adults ages 65 years and older. These needs may be associated with future health care utilization, but this research area has not been studied extensively. The objective of this study was to examine the independent association of 5 individual social needs with future (1) emergency department (ED) visits and (2) hospital admissions. This observational study included 9649 Kaiser Permanente Northwest (KPNW) Medicare members who completed the Medicare Total Health Assessment (MTHA) quality improvement survey between August 17, 2020 and January 31, 2022. The 5 social needs assessed by the MTHA, defined as binary measures (yes/no), included (1) financial strain, (2) food insecurity, (3) housing instability, (4) social isolation, and (5) transportation needs. ED utilization (yes/no) and hospitalization (yes/no), the current study outcome measures, were measured in the 12 months after MTHA assessment. In multivariable analyses, 3 of the 5 social needs were significantly associated with higher ED utilization: financial strain (odds ratio [OR] = 1.40, 95% confidence interval [CI] = 1.11-1.76, P < 0.05), housing instability (OR = 1.43, 95% CI = 1.02-1.99, P < 0.05), and social isolation (OR = 1.19, 95% CI = 1.05-1.34, P < 0.05), and 1, financial strain, was significantly associated with hospital admissions (OR = 1.66, 95% CI = 1.23-2.23, P < 0.05). The study results identified which social needs are most strongly associated with future ED utilization and hospital admissions. Further research is needed to better understand whether addressing social needs is associated with improved patient-level health outcomes over time.

The Association Between Social Isolation and Memory Loss Among Older Adults. J Am Board Fam Med 2022:jabfm.2022.AP.210497. [PMID: 36113995 DOI: 10.3122/jabfm.2022.ap.210497] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2021] [Revised: 12/20/2021] [Accepted: 06/30/2022] [Indexed: 03/21/2023] Open
Abstract
INTRODUCTION Social isolation among older individuals is associated with poor health outcomes. However, less is known about the association between social isolation and memory loss, specifically among Medicare enrollees in large, integrated health care systems. METHODS We conducted a cross-sectional, observational study. From a cohort of 46,240 Medicare members aged 65 years and older at Kaiser Permanente Northwest (KPNW) who completed a health questionnaire, we compared self-reported memory loss of those who reported feeling lonely or socially isolated and those who did not, adjusting for demographic factors, health conditions, and use of health services in the 12 months before the survey. RESULTS Patients who reported sometimes experiencing social isolation were more likely than those who rarely or never experienced social isolation to report memory loss in both unadjusted (odds ratio [ORsometimes]: 2.56, 95% CI= 2.42-2.70, P = 0.0076) and adjusted (ORsometimes: 2.45, 95% CI= 2.32-2.60, P = .0298) logistic regression models. Similarly, those who reported social isolation often or always were more likely to report memory loss than those who reported rarely or never experiencing isolation in both unadjusted (ORoften/always: 5.50, 95% CI = 5.06-5.99, P < .0001) and adjusted logistic regression models (ORoften/always: 5.20, 95% CI = 4.75-5.68, P < .0001). CONCLUSIONS The strong association between social isolation and memory loss suggest the need to develop interventions to reduce isolation and to evaluate their effects on potential future memory loss.

[PMID: 35348109 PMCID: PMC8782439 DOI: 10.7812/tpp/21.104] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2021] [Accepted: 08/16/2021] [Indexed: 11/30/2022]
Abstract
INTRODUCTION Use of kidney replacement therapy (KRT) prediction models for guiding arteriovenous fistula (AVF) referrals in advanced chronic kidney disease (CKD) is unknown. We aimed to compare a hypothetical approach using a KRT prediction model developed in Kaiser Permanente Northwest to estimated glomerular filtration rate (eGFR) for AVF referrals. METHODS Our retrospective cohort consisted of patients with stage G4 CKD in Kaiser Permanente Northwest followed by nephrology. Two-year KRT risk was calculated at each nephrology visit up to 2 years from entrance into cohort based on a previously published model. We calculated sensitivity, specificity, and area under the receiver operating characteristic curve (AUC) based on several 2-year KRT risk and eGFR cutoffs for outcome of hemodialysis at 18 months. We compared an approach of AVF referral using 2-year KRT risk and eGFR cutoffs using decision curve analysis. RESULTS Two-year KRT risk better discriminated progression to hemodialysis compared to eGFR < 15 mL/min (AUC 0.60 vs 0.69 at 2-year KRT risk > 20% and 0.69 at 2-year KRT risk > 40%, p = 0.003 and 0.006, respectively) but not to eGFR of 20 mL/min (AUC 0.64, p = 0.16 and 0.19, respectively). Decision curve analysis showed that AVF referral guided by 2-year KRT risk score resulted in higher net benefit compared to eGFR at low thresholds for referral. CONCLUSION In stage G4 CKD, a 2-year KRT risk model better predicted progression to KRT at 18 months compared to an eGFR of 15 mL/min but not to 20 mL/min and may improve timely referral for AVF placement in patients at lower thresholds for referral.

Abstract
INTRODUCTION Oral health is an important component of overall health, and preventive dental care is essential for maintaining good oral health. However, many patients face significant barriers to preventive dental care. We examined prevalence of and factors associated with no recent preventive dental care in an adult health plan population. METHODS For this cross-sectional study, we used data for 19,672 Kaiser Permanente members aged 25-85 who participated in the 2014/2015 or 2017 Member Health Survey (MHS) and 20,329 Medicaid members who completed an intake questionnaire. We estimated percentages of adults with no preventive dental care (teeth cleaning and examination by a dental professional) in the prior 12 months, overall and among four racial groups, by age, sex, education, income, and dental care cost factors. We used logistic regression to model associations of sociodemographic and cost factors with no preventive dental care. We also examined lack of preventive dental care in subgroups at elevated risk for periodontal disease. RESULTS Overall prevalence of no preventive dental care was 21%, with significant differences by race (non-Hispanic White, 19.6%; African-American/Black, 29.3%; Latinx, 24.9%, Asian American/Pacific Islander, 19.6%). Adults with lower educational attainment and household income and dental care cost barriers were more likely to lack preventive dental care. Racial and socioeconomic factors remained significant in the multivariable models. Lack of preventive dental care was fairly common among adults with diabetes, prediabetes, hypertension, smokers, frequent consumption of sugary beverages, and Medicaid coverage. CONCLUSION Oral health care should be better integrated with primary medical care to promote adult total health.

Evaluating the Effectiveness of Medical–Dental Integration to Close Preventive and Disease Management Care Gaps. FRONTIERS IN DENTAL MEDICINE 2021; 2. [PMID: 36213339 PMCID: PMC9536421 DOI: 10.3389/fdmed.2021.670012] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/21/2022] Open
Abstract
Background: The integration of medical care into the dental setting has been shown to facilitate the closure of care gaps among patients with unmet needs. However, little is known about whether program effectiveness varies depending on whether the care gap is related to preventive care or disease management. Materials and Methods: We used a matched cohort study design to compare closure of care gaps between patients aged 65+ who received care at a Kaiser Permanente Northwest (KPNW) Medical–Dental Integration (MDI) clinic or a non-MDI dental clinic between June 1, 2018, and December 31, 2019. The KPNW MDI program focuses on closing 12 preventive (e.g., flu vaccines) and 11 disease management care gaps (e.g., HbA1c testing) within the dental setting. Using the multivariable logistic regression, we separately analyzed care gap closure rates (yes vs. no) for patients who were overdue for: (1) preventive services only (n = 1,611), (2) disease management services only (n = 538), or (3) both types of services (n = 429), analyzing closure of each care gap type separately. All data were obtained through the electronic health record of KPNW. Results: The MDI patients had significantly higher odds of closing preventive care gaps (OR = 1.51, 95% CI = 1.30–1.75) and disease management care gaps (OR = 1.65, 95% CI = 1.27–2.15) than the non-MDI patients when they only had care gaps of one type or the other. However, no significant association was found between MDI and care gap closure when patients were overdue for both care gap types. Conclusions: Patients with care gaps related to either preventive care or disease management who received dental care in an MDI clinic had higher odds of closing these care gaps, but we found no evidence that MDI was helpful for those with both types of care gaps. Practical Implications: MDI may be an effective model for facilitating the delivery of preventive and disease management services, mainly when patients are overdue for one type of these services. Future research should examine the impact of MDI on long-term health outcomes.

Examining the association of medical-dental integration with closure of medical care gaps among the elderly population. J Am Dent Assoc 2021; 152:302-308. [PMID: 33775288 DOI: 10.1016/j.adaj.2020.12.010] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2020] [Revised: 11/04/2020] [Accepted: 12/28/2020] [Indexed: 10/21/2022]
Abstract
BACKGROUND The integration of medical and dental care in the dental setting offers a unique opportunity to close medical care gaps, such as providing immunizations and laboratory-based tests, compared with traditional nonintegrated settings. METHODS We used a matched cohort study design among patients 65 years or older (n = 2,578) with an index dental visit to the Kaiser Permanente Northwest medical-dental integration (MDI) program from June 1, 2018, through December 31, 2019. MDI patients were matched 1:1 to non-MDI controls (n = 2,578) on 14 characteristics. The Kaiser Permanente Northwest MDI program focuses on closing 23 preventive (for example, flu vaccines) and disease management care gaps (for example, glycated hemoglobin testing) within the dental setting. The closure of all care gaps (yes versus no) was the outcome for the analysis. Multivariable logistic regression was used to evaluate the association between exposure to the MDI program and level of office integration (least, moderate, and most integration) with closure of care gaps. All data were obtained through Kaiser Permanente Northwest's electronic health record. RESULTS MDI patients had significantly higher odds (odds ratio [OR], 1.46, 95% confidence interval [CI], 1.29 to 1.65) of closing all medical care gaps than non-MDI patients. Greater MDI integration was associated with significantly higher odds of gap closure compared with non-MDI (least integration: OR, 1.18, 95% CI, 1.02 to 1.37; moderate integration: OR, 1.70, 95% CI, 1.36 to 2.12; most integration: OR, 2.08, 95% CI, 1.73 to 2.50). CONCLUSIONS Patients receiving dental care in an MDI program had higher odds of closing medical care gaps compared with similar patients receiving dental care in a non-MDI program. PRACTICAL IMPLICATIONS MDI is effective at facilitating delivery of preventive and disease management medical services.

Abstract
INTRODUCTION Health systems and prescribers need additional tools to reduce the risk of opioid dependence, abuse, and overdose. Identifying opioid-naive individuals who are at risk of opioid dependence could allow for the development of needed interventions. METHODS We conducted a retrospective cohort analysis of 23,804 adults in an integrated health system who had received a first opioid prescription between 2010 and 2015. We compared the demographic, clinical, and prescribing characteristics of individuals who later received a third opioid dispense at least 27 days later, indicating long-term opioid use, with those who did not. RESULTS The strongest predictors of continued opioid use were an initial prescription dosage of 90 morphine milligram equivalence or more; prescription of extended-release opioids, rather than short-release; and being prescribed outside of a hospital setting. Patients with a third prescription were also more likely to be older than 45 years, white, and non-Hispanic and to have physical comorbidities or prior substance abuse or mental health diagnoses. DISCUSSION Our findings are largely consistent with prior research but provide new insight into differences in continued opioid use by opioid type, prescribing location, ethnicity, and comorbidities. Together with previous research, our data support a pattern of higher opioid use among older adults but higher rates of diagnosed opioid abuse among younger adults. CONCLUSIONS By identifying population characteristics associated with continued opioid use following a first prescription, our data pave the way for quality improvement interventions that target individuals who are at higher risk of opioid dependence.

Abstract
BACKGROUND AND OBJECTIVES Optimal timing of arteriovenous fistula placement in chronic kidney disease remains difficult and contributes to high central venous catheter use at initial hemodialysis. We tested whether a prediction model for progression to renal replacement therapy developed at Kaiser Permanente Northwest may help guide decisions about timing of referral for arteriovenous fistula placement. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS A total of 205 chronic kidney disease stage 4 patients followed by nephrology referred for arteriovenous fistula placement were followed for up to 2 years. Patients were censored if they died or discontinued Kaiser Permanente Northwest coverage. Survival analyses were performed for overall progression to renal replacement therapy divided by quartiles based on 2-year risk for renal replacement therapy and estimated glomerular filtrate rate at time of referral. RESULTS By 2 years, 60% progressed to renal replacement therapy and 11% had died. 80% in the highest risk versus 36% in the lowest risk quartile progressed to renal replacement therapy (predicted risk 84% vs 17%). 75% in the lowest estimated glomerular filtrate rate versus 56% in the highest estimated glomerular filtrate rate quartile progressed to renal replacement therapy (mean estimated glomerular filtrate rate 13 mL/min vs 21 mL/min). The hazard ratio was significantly higher for each consecutive higher renal replacement therapy quartile risk while for estimated glomerular filtrate rate, the hazard ratio was only significantly higher for the lowest compared to the highest quartile. The extreme quartile risk ratio was higher for 2-year risk for renal replacement therapy compared to estimated glomerular filtrate rate (4.0 vs 2.4). CONCLUSION In patients with chronic kidney disease stage 4 referred for arteriovenous fistula placement, 2-year renal replacement therapy risk better discriminated progression to renal replacement therapy compared to estimated glomerular filtrate rate at time of referral.

Abstract
Social isolation among individuals ages 65 years and older is associated with poor health outcomes. However, little is known about health care utilization patterns of socially isolated individuals. This retrospective, observational study evaluated associations between social isolation and hospital and emergency department (ED) utilization among Medicare patients ages 65 years and older. In a cohort of 18,557 Medicare members age 65 years and older at Kaiser Permanente Northwest, the authors compared rates of hospitalization and ED visits in the 12 months following a baseline survey between respondents who reported feeling lonely or socially isolated and those who did not, controlling for demographic and health variables and utilization in the 12 months prior to the survey. Statistical analysis was conducted in February 2020. In adjusted models, those who reported "sometimes" experiencing social isolation were more likely to have at least 1 hospital admission (odds ratio [ORsometimes]: 1.17, 95% confidence interval [CI]: 1.01-1.35, P = 0.04), than those who "rarely" or "never" experienced social isolation. Those who experienced social isolation "sometimes" or "often/always" were more likely to have at least 1 ED visit (ORsometimes: 1.28, 95% CI: 1.15-1.41, P < 0.0001, and ORoften/always: 1.51, 95% CI: 1.25-1.84, P < 0.0001, respectively) than those who "rarely" or "never" experienced social isolation. These findings suggest that self-reported social isolation may be predictive of future hospital admissions and ED utilization. Research is needed to determine how addressing social isolation needs within the health care system affects health care utilization and health outcomes.

Abstract
INTRODUCTION Unmet social and economic needs are associated with poor health outcomes, but little is known about how these needs are predictive of future healthcare utilization. This study examined the association of social and economic needs identified during medical visits with future hospitalizations and emergency department visits. METHODS Individuals with electronic health record-coded social and economic needs during a primary care, emergency department, or urgent care visit at Kaiser Permanente Northwest from October 1, 2016 to November 31, 2017 (case patients) were identified, as well as individuals who had visits during that time period but had no electronic health record-coded needs (control patients). The 2 groups were compared on sociodemographic characteristics, comorbidities, and healthcare utilization in the prior year. Finally, logistic regression assessed the relationship between documented needs and hospitalizations and emergency department visits in the 12 months following the index visit, controlling for sociodemographic characteristics, comorbidities, and prior healthcare utilization. Statistical analysis was completed in April 2019. RESULTS Case patients differed significantly from control patients on sociodemographic characteristics and had higher rates of comorbidities and prior healthcare utilization. Social and economic needs documented during the index visit were associated with significantly higher rates of hospitalization and emergency department visits in the 12 months following the visit, controlling for sociodemographic characteristics, comorbidities, and prior utilization. CONCLUSIONS These results demonstrate that documented social and economic needs are a powerful predictor of future hospitalization and emergency department use and suggest the need for research into whether interventions to address these needs can influence healthcare utilization.

Abstract
More than 3 million older US adults injure themselves by falling each year. Falls are a major cause of morbidity and mortality for this population, and account for nearly $30 billion in Medicare expenditures annually. Falls have been linked to frailty and vitamin D deficiency, both of which are linked to low nutrient intake and food insecurity. This retrospective, observational study is the first the authors know of to directly assess the relationship between food insecurity and falls. The study sample consisted of 26,525 Medicare Advantage members at Kaiser Permanente Northwest, a group model health maintenance organization, who had completed a quality of care survey between April 2013 and March 2017 and who maintained continuous enrollment in the 12 months prior to the survey date. Multivariable logistic regression analysis was used to assess the association between self-reported food insecurity and falls; electronic health record variables for age, sex, socioeconomic status, comorbidity, and health care utilization were included as covariates. Medicare Advantage members who reported food insecurity had 1.69 times higher odds of experiencing a fall in the past year than those without food insecurity, in adjusted analysis. Age, sex, comorbidity, and health care utilization also were significantly associated with falls. Food insecurity is significantly associated with falls among Medicare Advantage members. Routine assessment for food insecurity within the health care system, with subsequent referral to food resources, may help reduce rates of falls in older populations.

Abstract
Colorectal cancer (CRC) causes more than 50,000 deaths each year in the United States but early detection through screening yields survival gains; those diagnosed with early stage disease have a 5-year survival greater than 90%, compared to 12% for those diagnosed with late stage disease. Using data from a large integrated health system, this study evaluates the cost-effectiveness of fecal immunochemical testing (FIT), a common CRC screening tool. A probabilistic decision-analytic model was used to examine the costs and outcomes of positive test results from a 1-FIT regimen compared with a 2-FIT regimen. The authors compared 5 diagnostic cutoffs of hemoglobin concentration for each test (for a total of 10 screening options). The principal outcome from the analysis was the cost per additional advanced neoplasia (AN) detected. The authors also estimated the number of cancers detected and life-years gained from detecting AN. The following costs were included: program management of the screening program, patient identification, FIT kits and their processing, and diagnostic colonoscopy following a positive FIT. Per-person costs ranged from $33 (1-FIT at 150ng/ml) to $92 (2-FIT at 50ng/ml) across screening options. Depending on willingness to pay, the 1-FIT 50 ng/ml and the 2-FIT 50 ng/ml are the dominant strategies with cost-effectiveness of $11,198 and $28,389, respectively, for an additional AN detected. The estimates of cancers avoided per 1000 screens ranged from 1.46 to 4.86, depending on the strategy and the assumptions of AN to cancer progression.

Abstract
Objective To evaluate the impact of clinical decision support (CDS) tools on rates of vitamin D testing. Screening for vitamin D deficiency has increased in recent years, spurred by studies suggesting vitamin D's clinical benefits. Such screening, however, is often unsupported by evidence and can incur unnecessary costs. Materials and Methods We evaluated how rates of vitamin D screening changed after we implemented 3 CDS tools in the electronic health record (EHR) of a large health plan: (1) a new vitamin D screening guideline, (2) an alert that requires clinician acknowledgement of current guidelines to continue ordering the test (a "hard stop"), and (3) a modification of laboratory ordering preference lists that eliminates shortcuts. We assessed rates of overall vitamin D screening and appropriate vitamin D screening 6 months pre- and post-intervention. Results Vitamin D screening rates decreased from 74.0 tests to 24.2 tests per 1000 members ( P < .0001). The proportion of appropriate vitamin D screening tests increased from 56.2% to 69.7% ( P < .0001), and the proportion of inappropriate screening tests decreased from 43.8% pre-implementation to 30.3% post-implementation ( P < .0001). Discussion To our knowledge, this is the first demonstration of how CDS can reduce rates of inappropriate vitamin D screening. We used 3 straightforward, inexpensive, and replicable CDS approaches. We know of no previous research on the impact of removing options from a preference list. Conclusion Similar approaches could be used to reduce unnecessary care and decrease costs without reducing quality of care.

Abstract
CONTEXT Central venous catheter (CVC) use is associated with increased mortality and complications in hemodialysis recipients. Although prevalent CVC use has decreased, incident use remains high. OBJECTIVE To examine characteristics associated with CVC use at initial dialysis, specifically looking at proteinuria as a predictor of interest. DESIGN Retrospective cohort of 918 hemodialysis recipients from Kaiser Permanente Northwest who started hemodialysis from January 1, 2004, to January 1, 2014. MAIN OUTCOME MEASURES Multivariable logistic regression was used to examine an association of proteinuria with the primary outcome of CVC use. RESULTS More than one-third (36%) of patients in our cohort started hemodialysis with an arteriovenous fistula, and 64% started with a CVC. Proteinuria was associated with starting hemodialysis with a CVC (likelihood ratio test, p < 0.001) after adjustment for age, peripheral vascular disease, congestive heart failure, diabetes, sex, race, and length of predialysis care. However, on pairwise comparison, only patients with midgrade proteinuria (0.5-3.5 g) had lower odds of starting hemodialysis with a CVC (odds ratio = 0.39, 95% confidence interval = 0.24-0.65). CONCLUSION Proteinuria was associated with use of CVC at initial hemodialysis. However, a graded association did not exist, and only patients with midgrade proteinuria had significantly lower odds of CVC use. Our findings suggest that proteinuria is an explanatory finding for CVC use but may not have pragmatic value for decision making. Patients with lower levels of proteinuria may have a higher risk of starting dialysis with a CVC.

METHODS We surveyed 234 dental providers in an integrated health care setting in Portland, Oregon, in March-April 2015. We assessed participants' knowledge of adolescent vaccines, barriers to recommending vaccines, and their perceived role in the promotion of vaccination and preventive medical care. RESULTS Over 80 percent of respondents correctly identified influenza, tetanus-diphtheria-acellular pertussis, and human papillomavirus as vaccinations recommended for adolescents; 60 percent correctly identified meningococcal conjugate. Forty-four percent of providers reported previously discussing vaccination with their adolescent patients. Lack of knowledge (66 percent), uncertainty about whether patients would accept recommendations (62 percent), and lack of time (61 percent) were commonly reported barriers. While few providers expressed personal concerns about the safety (13 percent) and effectiveness (10 percent) of adolescent vaccines, most believed parents had concerns about safety (70 percent) and effectiveness (60 percent). Although 80 percent endorsed the premise that providers should discuss preventive medical care with their patients, only 54 percent said they should discuss vaccinations specifically. CONCLUSIONS Dental providers reported several barriers to recommending vaccines. While comfortable with discussing preventive medical care in general, providers are less comfortable making vaccine recommendations to their patients. Vaccine recommendations are not a traditional practice among dental providers and may require additional education and communication tools.

Use of posttreatment imaging and biomarkers in survivors of early-stage breast cancer: Inappropriate surveillance or necessary care? Cancer 2015; 122:908-16. [PMID: 26650715 DOI: 10.1002/cncr.29811] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2015] [Revised: 10/23/2015] [Accepted: 11/05/2015] [Indexed: 11/07/2022]
Abstract
BACKGROUND Advanced imaging and serum biomarkers are commonly used for surveillance in patients with early-stage breast cancer, despite recommendations against this practice. Incentives to perform such low-value testing may be less prominent in integrated health care delivery systems. The purpose of the current study was to evaluate and compare the use of these services within 2 integrated systems: Kaiser Permanente (KP) and Intermountain Healthcare (IH). The authors also sought to distinguish the indication for testing: diagnostic purposes or routine surveillance. METHODS Patients with American Joint Committee on Cancer stage 0 to II breast cancer diagnosed between 2009 and 2010 were identified and the use of imaging and biomarker tests over an 18-month period were quantified, starting at 1 year after diagnosis. Chart abstraction was performed on a random sample of patients who received testing to identify the indication for testing. Multivariate regression was used to explore associations with the use of nonrecommended care. RESULTS A total of 6585 patients were identified; 22% had stage 0 disease, 44% had stage I disease, and 34% had stage II disease. Overall, 24% of patients received at least 1 imaging test (25% at KP vs 22% at IH; P = .009) and 28% of patients received at least 1 biomarker (36% at KP vs 13% at IH; P<.001). Chart abstraction revealed that 84% of imaging tests were performed to evaluate symptoms or signs. Virtually all biomarkers were ordered for routine surveillance. Stage of disease, medical center that provided the services, and provider experience were found to be significantly associated with the use of biomarkers. CONCLUSIONS Advanced imaging was most often performed for appropriate indications, but biomarkers were used for nonrecommended surveillance. Distinguishing between inappropriate use for surveillance and appropriate diagnostic testing is essential when evaluating adherence to recommendations.

Abstract
PURPOSE Advanced imaging is commonly used for staging of early-stage breast cancer, despite recommendations against this practice. The objective of this study was to evaluate and compare use of imaging for staging of breast cancer in two integrated health care systems, Kaiser Permanente (KP) and Intermountain Healthcare (IH). We also sought to distinguish whether imaging was routine or used for diagnostic purposes. METHODS We identified patients with stages 0 to IIB breast cancer diagnosed between 2010 and 2012. Using KP and IH electronic health records, we identified use of computed tomography, positron emission tomography, or bone scintigraphy 30 days before diagnosis to 30 days postsurgery. We performed chart abstraction on a random sample of patients who received a presurgical imaging test to identify indication. RESULTS For the sample of 10,010 patients, mean age at diagnosis was 60 years (range, 22 to 99 years); with 21% stage 0, 47% stage I, and 32% stage II. Overall, 15% of patients (n = 1,480) received at least one imaging test during the staging window, 15% at KP and 14% at IH (P = .5). Eight percent of patients received imaging before surgery, and 7% postsurgery. We found significant intraregional variation in imaging use. Chart abstraction (n = 129, 16% of patients who received presurgical imaging) revealed that 48% of presurgical imaging was diagnostic. CONCLUSION Use of imaging for staging of low-risk breast cancer was similar in both systems, and slightly lower than has been reported in the literature. Approximately half of imaging tests were ordered in response to a sign or symptom.

Implementation challenges and successes of a population-based colorectal cancer screening program: a qualitative study of stakeholder perspectives. Implement Sci 2015; 10:41.

Abstract
Background Few studies describe system-level challenges or facilitators to implementing population-based colorectal cancer (CRC) screening outreach programs. Our qualitative study explored viewpoints of multilevel stakeholders before, during, and after implementation of a centralized outreach program. Program implementation was part of a broader quality-improvement initiative. Methods During 2008–2010, we conducted semi-structured, open-ended individual interviews and focus groups at Kaiser Permanente Northwest (KPNW), a not-for-profit group model health maintenance organization using the practical robust implementation and sustainability model to explore external and internal barriers to CRC screening. We interviewed 55 stakeholders: 8 health plan leaders, 20 primary care providers, 4 program managers, and 23 endoscopy specialists (15 gastroenterologists, 8 general surgeons), and analyzed interview transcripts to identify common as well as divergent opinions expressed by stakeholders. Results The majority of stakeholders at various levels consistently reported that an automated telephone-reminder system to contact patients and coordinate mailing fecal tests alleviated organizational constraints on staff’s time and resources. Changing to a single-sample fecal immunochemical test (FIT) lessened patient and provider concerns about feasibility and accuracy of fecal testing. The centralized telephonic outreach program did, however, result in some screening duplication and overuse. Higher rates of FIT completion and a higher proportion of positive results with FIT required more colonoscopies. Conclusions Addressing barriers at multiple levels of a health system by changing the delivery system design to add a centralized outreach program, switching to a more accurate and easier-to-use fecal test, and providing educational and electronic support had both benefits and problematic consequences. Other health care organizations can use our results to understand the complexities of implementing centralized screening programs.

Abstract
184 Background: The initial ASCO “Top 5” list, created as part of the Choosing Wisely campaign, recommends against use of imaging for staging of early stage breast cancer in asymptomatic women at low risk for metastasis. The objective of this study was to measure and compare use of imaging for staging in two large integrated health care systems, Kaiser Permanente (KP) and Intermountain Healthcare (IH). We also sought to distinguish whether imaging was used for routine staging or for diagnostic purposes. Methods: We identified stage 0-IIB breast cancer patients diagnosed between January 1, 2010 and December 31, 2012 with first primary malignancy from tumor registries in three KP regions (Southern California, Northwest, and Mid-Atlantic) and IH. Using the KP and IH electronic health records, we identified use of imaging tests (PET, CT, bone scan) during the staging window (30 days prior to diagnosis up to initial surgery). We performed chart abstraction on a random sample of patients who received an imaging test to identify indication. Results: For the total sample of 10,014, mean age at diagnosis was 60 (range 22-99); with 21% stage 0, 47% stage I, 32% stage II. Overall, 8% of patients (792 patients) received at least one imaging test during the staging window, including 8% at KP and 6% at IH (p=0.0005). Chart abstraction (N=129) revealed that overall, almost half of all imaging tests (48%) were performed to evaluate a symptom, sign or prior imaging finding, including 55% at KP and 32% at IH. Conclusions: Use of imaging for staging of low-risk breast cancer was very low in both health care systems, with clinically trivial differences between them. Approximately half of imaging services were in response to a sign or symptom. Strategies to reduce use of imaging at staging for early stage breast cancer patients within these health care systems are unlikely to yield meaningful improvement. [Table: see text]

Long-term persistence of quality improvements for an intensive care unit communication initiative using the VALUE strategy. J Crit Care 2013; 29:450-4. [PMID: 24456811 DOI: 10.1016/j.jcrc.2013.12.006] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2013] [Revised: 11/05/2013] [Accepted: 12/14/2013] [Indexed: 10/25/2022]
Abstract
PURPOSE Communication in the intensive care unit (ICU) is an important component of quality ICU care. In this report, we evaluate the long-term effects of a quality improvement (QI) initiative, based on the VALUE communication strategy, designed to improve communication with family members of critically ill patients. MATERIALS AND METHODS We implemented a multifaceted intervention to improve communication in the ICU and measured processes of care. Quality improvement components included posted VALUE placards, templated progress note inclusive of communication documentation, and a daily rounding checklist prompt. We evaluated care for all patients cared for by the intensivists during three separate 3 week periods, pre, post, and 3 years following the initial intervention. RESULTS Care delivery was assessed in 38 patients and their families in the pre-intervention sample, 27 in the post-intervention period, and 41 in follow-up. Process measures of communication showed improvement across the evaluation periods, for example, daily updates increased from pre 62% to post 76% to current 84% of opportunities. CONCLUSIONS Our evaluation of this quality improvement project suggests persistence and continued improvements in the delivery of measured aspects of ICU family communication. Maintenance with point-of-care-tools may account for some of the persistence and continued improvements.

Abstract
OBJECTIVES To establish longitudinal validation of a new tool, the Asthma Symptom Tracker (AST). AST combines weekly use of the Asthma Control Test with a color-coded graph for visual trending. METHODS Prospective cohort study of children age 2 to 18 years admitted for asthma. Parents or children (n = 210) completed baseline AST assessments during hospitalization, then over 6 months after discharge. Concurrent with the first 5 AST assessments, the Asthma Control Questionnaire (ACQ) was administered for comparison. RESULTS Test-retest reliability (intraclass correlation) was moderate, with a small longitudinal variation of AST measurements within subjects during follow-ups. Internal consistency was strong at baseline (Cronbach's α 0.70) and during follow-ups (Cronbach's α 0.82-0.90). Criterion validity demonstrated a significant correlation between AST and ACQ scores at baseline (r = -0.80, P < .01) and during follow-ups (r = -0.64, -0.72, -0.63, and -0.69). The AST was responsive to change over time; an increased ACQ score by 1 point was associated with a decreased AST score by 2.65 points (P < .01) at baseline and 3.11 points (P < .01) during follow-ups. Discriminant validity demonstrated a strong association between decreased AST scores and increased oral corticosteroid use (odds ratio 1.13, 95% confidence interval, 1.10-1.16, P < .01) and increased unscheduled acute asthma visits (odds ratio 1.23, 95% confidence interval, 1.18-1.28, P < .01). CONCLUSIONS The AST is reliable, valid, and responsive to change over time, and can facilitate ongoing monitoring of asthma control and proactive medical decision-making in children.

Abstract
OBJECTIVES Examine association of comprehensiveness of colorectal cancer (CRC) screening discussion by primary care physicians (PCPs) with completion of CRC screening. STUDY DESIGN Observational study in Kaiser Permanente Northwest, a group-model health maintenance organization. METHODS A total of 883 participants overdue for CRC screening received an automated telephone call (ATC) between April and June 2009 encouraging CRC screening. Between January and March 2010, participants completed a survey on PCPs' discussion of CRC screening and patient beliefs regarding screening. PRIMARY OUTCOME MEASURE receipt of CRC screening (assessed by electronic medical record [EMR], 9 months after ATC). Primary independent variable: comprehensiveness of CRC screening discussion by PCPs (7-item scale). Secondary independent variables: perceived benefits of screening (4-item scale assessing respondents' agreement with benefits of timely screening) and primary care utilization (EMR; 9 months after ATC). The independent association of variables with CRC screening was assessed with logistic regression. RESULTS Average scores for comprehensiveness of CRC discussion and perceived benefits were 0.4 (range 0-1) and 4.0 (range 1-5), respectively. A total of 28.2% (n = 249) completed screening, 84% of whom had survey assessments after their screening date. Of screeners, 95.2% completed the fecal immunochemical test. More comprehensive discussion of CRC screening was associated with increased screening (odds ratio [OR] = 1.51, 95% confidence interval [CI] = 1.03-2.21). Higher perceived benefits (OR = 1.46, 95% CI = 1.13-1.90) and 1 or more PCP visits (OR = 5.82, 95% CI = 3.87-8.74) were also associated with increased screening. CONCLUSIONS More comprehensive discussion of CRC screening was independently associated with increased CRC screening. Primary care utilization was even more strongly associated with CRC screening, irrespective of discussion of CRC screening.

Abstract
OBJECTIVES To estimate the cost-effectiveness of an automated telephone intervention for colorectal cancer screening from a managed care perspective, using data from a pragmatic randomized controlled trial. METHODS Intervention patients received calls for fecal occult blood testing (FOBT) screening. We searched patients' electronic medical records for any screening (defined as FOBT, flexible sigmoidoscopy, double-contrast barium enema, or colonoscopy) during follow-up. Intervention costs included project implementation and management, telephone calls, patient identification, and tracking. Screening costs included FOBT (kits, mailing, and processing) and any completed screening tests during follow-up. We estimated the incremental cost-effectiveness ratio (ICER) of the cost per additional screen. RESULTS At 6 months, average costs for intervention and control patients were $37 (25% screened) and $34 (19% screened), respectively. The ICER at 6 months was $42 per additional screen, less than half what other studies have reported. Cost-effectiveness probability was 0.49, 0.84, and 0.99 for willingness-to-pay thresholds of $40, $100, and $200, respectively. Similar results were seen at 9 months. A greater increase in FOBT testing was seen for patients aged >70 years (45/100 intervention, 33/100 control) compared with younger patients (25/100 intervention, 21/100 control). The intervention was dominant for patients aged >70 years and was $73 per additional screen for younger patients. It increased screening rates by about 6% and costs by $3 per patient. CONCLUSIONS At willingness to pay of $100 or more per additional screening test, an automated telephone reminder intervention can be an optimal use of resources.

Abstract
OBJECTIVES To compare completion rates of colorectal cancer screening tests within a health maintenance organization before and after widespread adoption of the fecal immunochemical test (FIT). STUDY DESIGN Retrospective cohort study. METHODS Using electronic medical records of 113,901 patients eligible for colorectal cancer screening, we examined test completion during 2 successive time periods among those who received an automated screening outreach call. The time periods were: 1) the "guaiac fecal occult blood test (gFOBT) era," a 15-month period during which only gFOBT was routinely offered, and 2) a 9-month "FIT era," when only a new FIT was routinely offered. In addition to analyzing completion rates, we analyzed the impact of practice-level variables and patient-level variables on overall screening completion during the 2 different observation periods. RESULTS The change from gFOBT to FIT in an integrated care delivery system increased the likelihood of screening completion by 7.7% overall, and the likelihood of screening with a fecal test by 8.9%. The greatest gains in screening completion using FIT were among women and elderly patients. Completion of FIT was not as strongly associated with medical office visits or with having a primary care provider as was screening with gFOBT. CONCLUSIONS Adoption of FIT within an integrated care system increased completion of colon cancer screening tests within a 9-month assessment period, compared with a previous 15-month gFOBT era. Higher completion rates of the FIT may allow for more effective dissemination of programs to increase colorectal cancer screening through centralized outreach programs.

Abstract
CONTEXT Perioperative hyperglycemia is a risk factor for increased morbidity and mortality. Improved glycemic control has been demonstrated to reduce surgical site infections, reduce perioperative morbidity, and reduce length of stay. However, safe and effective perioperative glycemic control can be limited by expert clinician availability. OBJECTIVE To improve quality by reliably providing safe and effective glycemic control to surgical patients with diabetes or stress hyperglycemia. DESIGN A designated group of pharmacists, the Glycemic Control Team (GCT), worked under protocol, on a consultation basis, to manage perioperative dysglycemia during hospitalization. We used a pre-post, observational study design to assess the effectiveness of the intervention and implementation of the GCT. MAIN OUTCOME MEASURES The proportion of patients pre- and postintervention with good glycemic control and with hypoglycemia were measured and compared. We defined good glycemic control as having all, or all but one, point-of-care blood glucose values between 70-180 mg/dL in each 24-hour period. We defined hypoglycemia as having any point-of-care test glucose value <70 mg/dL in any of the 3 days evaluated. RESULTS During the preimplementation period, 77.4% of postoperative patient days demonstrated good glycemic control. In the postimplementation period, this percentage increased to 90.3%. Over the same period, the rate of hypoglycemia decreased from 8.6% to 4.6%. CONCLUSION Implementation of a pharmacist team to manage glycemic control in hospitalized, postoperative patients led to safer and better quality of glycemic care as measured by improved glycemic control and lower rates of hypoglycemia.

Abstract
BACKGROUND The relationship of a primary care provider's (PCP's) colorectal cancer (CRC) screening strategies to completion of screening is poorly understood. OBJECTIVE To describe PCP test recommendation patterns and associated factors and their relationship to patient test completion. DESIGN This cross-sectional study used a PCP survey, in-depth PCP interviews, and electronic medical records. SETTING Kaiser Permanente Northwest health maintenance organization. PARTICIPANTS Participants included 132 PCPs and 49,259 eligible patients aged 51 to 75. MEASUREMENTS The authors grouped PCPs by patterns of CRC screening recommendations based on reported frequency of recommending fecal occult blood testing (FOBT), flexible sigmoidoscopy (FS), and colonoscopy. They then compared PCP demographics, reported CRC screening test influences, concerns, decision-making and counseling processes, and actual rates of patient CRC screening completion by PCP group. RESULTS The authors identified 4 CRC screening recommendation groups: a "balanced" group (n = 54; 40.9%) that recommended the tests nearly equally, an FOBT group (n = 31; 23.5%) that largely recommended FOBT, an FOBT + FS group (n = 25; 18.9%), and a colonoscopy + FOBT group (n = 22; 16.7%) that recommended these tests nearly equally. Internal medicine (v. family medicine) PCPs were more common in groups more frequently recommending endoscopy. The FOBT and FOBT + FS groups were most influenced by clinical guidelines. Groups recommending more endoscopy were most concerned that FOBT generates a relatively high number of false positives and FOBT can miss cancers. The FOBT and FOBT + FS groups were more likely to recommend a specific screening strategy compared to the colonoscopy + FOBT and balanced groups, which were more likely to let the patient decide. CRC screening rates were 63.9% balanced, 62.9% FOBT, 61.7% FOBT + FS, and 62.2% colonoscopy + FOBT; rates did not differ significantly by group. LIMITATIONS Small numbers within PCP groups. CONCLUSIONS Specialty, the influence of guidelines, test concerns, and the "jointness" of the test selection decision distinguished CRC screening recommendation patterns. All patterns were associated with similar overall screening rates.

Abstract
OBJECTIVES To determine whether adding selfreported health and functional status data to a diagnostic risk-score model explains additional variance in predicting inpatient admissions and costs. STUDY DESIGN Retrospective observational analysis. METHODS We used data from a Health Status Questionnaire (HSQ), completed by 6407 Kaiser Permanente Northwest Medicare patients between December 2006 and October 2008. We used answers from 3 items on the HSQ: (1) General Self-rated Health score, (2) needing help with 1 or more activities of daily living, and (3) having a bothersome health condition. We calculated a DxCG relative risk score from utilization information in the year prior to the survey, using electronic medical records. We compared: (1) DxCG as the sole independent variable and (2) DxCG plus the 3 items as independent variables. We estimated area under the curve (AUC) for each model. Any inpatient admission (yes/no) and being in the top 10% of costs (in the year after survey) were the dependent variables for the first and second logistic regression models, respectively. RESULTS The 3 items explained an additional 2.8% and 4.0% of variance for inpatient admissions and top 10% of costs,respectively, in addition to the variance explained by the DxCG score alone. For DxCG alone, the AUC was 0.686 (95% confidence interval [CI] 0.663-0.710) and 0.741 (95% CI 0.719- 0.764), respectively, for inpatient admissions and top 10% of costs and improved to 0.709 (95% CI 0.687-0.730) and 0.770 (95% CI 0.749-0.790) when the 3 self-reported items were added. CONCLUSIONS Using self-reported health information improved the predictive power of a DxCG model to forecast inpatient admissions and patient cost-tier.

Abstract
OBJECTIVES We determined how elimination of dental benefits among adult Medicaid beneficiaries in Oregon affected their access to dental care, Medicaid expenditures, and use of medical settings for dental services. METHODS We used a natural experimental design using Medicaid claims data (n = 22 833) before and after Medicaid dental benefits were eliminated in Oregon in 2003 and survey data for continuously enrolled Oregon Health Plan enrollees (n = 718) covering 3 years after benefit cuts. RESULTS Claims analysis showed that, compared with enrollees who retained dental benefits, those who lost benefits had large increases in dental-related emergency department use (101.7%; P < .001) and expenditures (98.8%; P < .001) and in all ambulatory medical care use (77.0%; P < .01) and expenditures (114.5%; P < .01). Survey results indicated that enrollees who lost dental benefits had nearly 3 times the odds (odds ratio = 2.863; P = .001) of unmet dental need, and only one third the odds (odds ratio = 0.340; P = .001) of getting annual dental checkups relative to those retaining benefits. CONCLUSIONS Combined evidence from both analyses suggested that the elimination of dental benefits resulted in significant unmet dental health care needs, which led to increased use of medical settings for dental problems.

Abstract
OBJECTIVES To examine the association of race/ethnicity with medication use, emergency hospital care (EHC) utilization, and quality-of-life outcomes in a population with persistent asthma and to determine if factors related to severity of illness, treatment characteristics, and demographic, socioeconomic, and smoking status explain differences in study outcomes. STUDY DESIGN Retrospective analysis. METHODS We examined survey and administrative data for 974 adults with persistent asthma enrolled in a group-model health maintenance organization. Patients with persistent asthma were identified in 1999 using Healthcare Effectiveness Data and Information Set inclusion criteria. In 2000, the same patients were surveyed regarding quality of life using the Mini Asthma Quality of Life Questionnaire. In 2001, the use of controller medications, the ratio of controller medications to rescue medications, and EHC utilization were identified by electronic medical record. Multiple logistic regression and linear regression analyses were used to evaluate the independent association of race/ethnicity with study outcomes after adjusting for severity of illness, treatment characteristics, and demographic, socioeconomic, and smoking status. RESULTS Compared with whites, African Americans (standardized β coefficient, -0.12) and Native Americans/Aleutians/Eskimos (standardized β coefficient, -0.14) had lower Mini Asthma Quality of Life Questionnaire scores (P <.05 for both). African Americans were significantly (P <.05) more likely to report EHC utilization (odds ratio, 5.2; 95% confidence interval, 2.6-10.3). CONCLUSIONS Disparities existed in 2 outcome measures, Mini Asthma Quality of Life Questionnaire scores and EHC utilization. A concerning finding is that African Americans were at least 5 times more likely to report higher EHC utilization, even after adjusting for factors such as income and education.

Abstract
OBJECTIVE: To develop and test an online assessment referred to as the ASTHMA-CAT (computerized adaptive testing), a patient-based asthma impact, control, and generic health-related quality of life (HRQOL) measure. STUDY DESIGN: Cross-sectional pilot study of the ASTHMA-CAT's administrative feasibility in a disease management population. METHODS: The ASTHMA-CAT included a dynamic or static Asthma Impact Survey (AIS), Asthma Control Test, and SF-8 Health Survey. A sample of clinician-diagnosed adult asthmatic patients (N = 114) completed the ASTHMA-CAT. Results were used to evaluate administrative feasibility of the instrument and psychometric performance of the dynamic AIS relative to the static AIS. A prototype aggregate (group-level) report was developed and reviewed by care providers. RESULTS: Online administration of the ASTHMA-CAT was feasible for patients in disease management. The dynamic AIS functioned well compared with the static AIS in preliminary studies evaluating response burden, precision, and validity. Providers found reports to be relevant, useful, and applicable for care management. CONCLUSION: The ASTHMA-CAT may facilitate asthma care management.

Abstract
OBJECTIVES Combination antiretroviral therapy (cART) is associated with increased survival among HIV-infected persons. Yet, no research to date has examined whether introduction of once-daily fixed-dosed combinations (FDC) affects the likelihood of cART initiation. We aimed to determine whether implementation of once-daily FDC regimens was associated with changes to cART initiation. We also identified clinical, treatment regimen, and provider characteristics possibly associated with cART initiation. STUDY DESIGN Retrospective observational analysis. METHODS We queried electronic medical records between July 1999-June 2006 to identify incident cases of detectable HIV infection in antiretroviral-naïve adults. Cox regression with time-dependent covariates was used to examine the effects of once-daily FDC era, clinical, provider, and treatment regimen characteristics on cART initiation. RESULTS Once-daily FDC availability did not change the likelihood of cART initiation, but other characteristics were associated with an increased likelihood: AIDS diagnosis, above-median daily pill consumption, and 16+ yrs of physician HIV experience. Decreased likelihood of cART initiation was associated with CD4 201-350 cells/μL, HIV RNA < 100,000 copies/mL, and with CD4 > 350 cells/μL (any HIV RNA level), compared to CD4 ≤ 200 cells/μL. CONCLUSION Availability of once-daily FDC-based regimens did not affect likelihood of cART initiation. Patient clinical characteristics appear to be more important predictors of cART initiation.

Abstract
BACKGROUND The Agency for Healthcare Research and Quality ranks prevention of venous thromboembolism (VTE) as a top priority for patient safety; however, no guidelines or population-based research exist to guide management for podiatric surgery patients. The objective of our study was to determine the incidence and risk factors for postprocedure VTE in podiatric surgery. METHODS A 5-year retrospective analysis of patients undergoing podiatric surgery in a large not-for-profit health maintenance organization serving > 485,000 members in the Pacific Northwest from 1999 to 2004. RESULTS We identified 16,804 surgical procedures in 7,264 patients and detected 22 symptomatic postprocedure VTEs. The overall incidence of postprocedure VTE was 0.30%. Three risk factors were significantly and independently associated with VTE in podiatric surgery: prior VTE (incidence, 4.6%; relative risk, 23.0; p < 0.001), use of hormone replacement therapy or oral contraceptives (incidence, 0.55%; relative risk, 4.2; p = 0.01), and obesity (incidence, 0.48%; relative risk, 3.0; p = 0.02). CONCLUSIONS We identified a low overall risk of VTE in podiatric surgery, suggesting that routine prophylaxis is not warranted. However, for patients with a history of VTE, periprocedure prophylaxis is suggested based on the level of risk. For podiatry surgery patients with two or more risk factors for VTE, periprocedure prophylaxis should be considered. Until a prospective study is completed testing recommendations, guidelines and care decisions for podiatric surgery patients will continue to be based on retrospective data, expert consensus, and clinical judgment.

Abstract
BACKGROUND The association of obesity with asthma outcomes is not well understood. OBJECTIVE The objective of this study was to examine the association of obesity, as represented by a body mass index (BMI) of greater than 30 kg/m(2), with quality-of-life scores, asthma control problems, and asthma-related hospitalizations. METHODS The study followed a cross-sectional design. Questionnaires were completed at home by a random sample of 1113 members of a large integrated health care organization who were 35 years of age or older with health care use suggestive of active asthma. Outcomes included the mini-Asthma Quality of Life Questionnaire, the Asthma Therapy Assessment Questionnaire, and self-reported asthma-related hospitalization. Several other factors known to influence asthma outcomes also were collected: demographics, smoking status, oral corticosteroid use in the past month, evidence of gastroesophageal reflux disease, and inhaled corticosteroid use in the past month. Multiple logistic regression models were used to measure the association of BMI status with outcomes. RESULTS Even after adjusting for demographics, smoking status, oral corticosteroid use, evidence of gastroesophageal reflux disease, and inhaled corticosteroid use, obese adults were more likely than those with normal BMIs (<25 kg/m(2)) to report poor asthma-specific quality of life (odds ratio [OR], 2.8; 95% CI, 1.6-4.9), poor asthma control (OR, 2.7; 95% CI, 1.7-4.3), and a history of asthma-related hospitalizations (OR, 4.6; 95% CI, 1.4-14.4). CONCLUSIONS Our findings suggest that obesity is associated with worse asthma outcomes, especially an increased risk of asthma-related hospitalizations.

Abstract
BACKGROUND The Patient Assessment of Chronic Illness Care (PACIC) has potential for use as a patient-centered measure of the implementation of the Chronic Care Model (CCM), but there is little research on the relationship between the PACIC and important behavioral and quality measures for patients with chronic conditions. OBJECTIVE To examine the relationship between PACIC scores and self-management behaviors, patient rating of their health care, and self-reported quality of life. DESIGN Cross-sectional survey with a 61% response rate. PARTICIPANTS Included in the survey were 4,108 adults with diabetes, chronic pain, heart failure, asthma, or coronary artery disease in the Kaiser Permanente Medical Care program across 7 regions nationally. MEASUREMENTS The PACIC was the main independent variable. Dependent variables included use of self-management resources, self-management behaviors such as regular exercise, self-reported adherence to medications, patient rating of their health care, and quality of life. RESULTS PACIC scores were significantly, positively associated with all measures (odds ratio [ORs] ranging from 1.20 to 2.36) with the exception of self-reported medication adherence. CONCLUSIONS Use of the PACIC, a practical, patient-level assessment of CCM implementation, could be an important tool for health systems and other stakeholders looking to improve the quality of chronic disease care.

Validity of the Asthma Control Test completed at home. THE AMERICAN JOURNAL OF MANAGED CARE 2007; 13:661-667. [PMID: 18069909] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Subscribe] [Scholar Register] [Indexed: 05/25/2023]
Abstract
OBJECTIVE To provide additional validity data for the Asthma Control TestTM (ACT) using a different criterion measure, setting, and population. STUDY DESIGN Cross-sectional survey. METHODS Questionnaires were completed at home by a random sample of 570 members of a large integrated healthcare organization who were 35 years or older with utilization suggestive of active asthma. The questionnaires included the ACT; another validated asthma control questionnaire (Asthma Therapy Assessment Questionnaire [ATAQ]), which was used as the criterion measure; a validated quality-of-life tool (Mini Asthma Quality of Life Questionnaire [Mini-AQLQ]); a validated symptom frequency scale (Asthma Outcomes Monitoring System); and information regarding demographics. RESULTS The ACT score was statistically significantly correlated with findings on the ATAQ (P = -0.73), Mini-AQLQ (P = 0.77), and symptom frequency scale (P = -0.69). The optimal ACT cutoff for well-controlled asthma (ATAQ level, 0) was confirmed to be 20 or higher (sensitivity, 78.1%; specificity, 83.8%), and the optimal ACT cutoff for poorly controlled asthma (ATAQ level, 3-4) was confirmed to be 15 or lower (sensitivity, 90.4%; specificity, 80.9%). CONCLUSION These data further support the validity of the ACT in the home setting among a random sample of patients with asthma.

Abstract
BACKGROUND Temporal artery biopsy is the traditionally-accepted method of diagnosing temporal arteritis, but is of limited sensitivity. AIM To compare the clinical decisions made after negative temporal artery biopsy vs. negative temporal artery duplex, and the effects on patient outcomes. DESIGN Retrospective analysis. METHODS Of 290 patients suspected of having temporal arteritis, 147 underwent bilateral temporal artery duplex with a negative result, and 143 underwent unilateral temporal artery biopsy with a negative result. These groups were compared. Dependent measures included the proportion of patients in each group whose steroids were discontinued by their primary care doctor after either negative test, and the difference in the number of alternative diagnoses considered after a negative test. The incidence of blindness in each group was also compared, as a measure of adverse outcomes. Patients were then stratified by pre-test probability of having the disease, and compared using the same measures. RESULTS Equivalent proportions of patients in the two groups had steroids discontinued after a negative test result, even when further stratified into risk groups by the probability of having temporal arteritis. No differences in adverse outcomes or number of alternative diagnoses considered were noted between groups. DISCUSSION In clinical practice, bilateral temporal artery duplex served the same function as biopsy, but without subjecting patients to the potential morbidity of a surgical procedure. Temporal artery biopsy could be reserved only for situations where the duplex result is inconsistent with the clinical picture, and the biopsy result, if different from the duplex result, might influence the treatment decision.

Abstract
Few studies have quantitatively addressed the relationship between asthma-specific quality of life and asthma control as assessed by validated tools. Questionnaires were completed at home by a random sample of 542 adult asthmatic patients. The correlations of the two asthma control tools (Asthma Control Test and Asthma Therapy Assessment Questionnaire) with the quality of life tool (mini-Asthma Quality of Life Questionnaire) were strongest with the symptoms and activity domains (r = 0.63-0.77); lower with the emotions domain (r = 0.57-0.64); and lowest with the environment domain (r = 0.38-0.43). Asthma control tools reflect the symptoms and activity themes of asthma quality of life well, but reflect the environmental domain less well.

Abstract
The purpose of this study was to identify determinants of asthma control. Questionnaires were completed by a random sample of 570 members of a large managed care organization who were >or=35 years of age with utilization suggestive of active asthma. Asthma control was assessed buy the Asthma Control Test (ACT). Independent relationships were found between lower ACT scores and oral corticosteroid use (p < 0.0001), COPD (p < 0.0001), absence of regular specialist care (p = 0.006), higher BMI (p = 0.01), gastroesophageal reflux (p = 0.02), not being Caucasian (p = 0.04), and low income (p = 0.04).

Abstract
We examined the patient activation measure's (PAM's) association with process and health outcomes among adults with chronic conditions. Patients with high PAM scores were significantly more likely to perform self-management behaviors, use self-management services, and report high medication adherence, compared to patients with the lowest PAM scores. This population was 10 times more likely to report high patient-satisfaction scores, 5 times more likely to report high quality-of-life scores, and reported significantly higher physical and mental functional status scores, compared to those with the lowest scores. These results suggest that PAM scores are associated with key process and health outcome measures.

How well do the HEDIS asthma inclusion criteria identify persistent asthma? THE AMERICAN JOURNAL OF MANAGED CARE 2005; 11:650-4.

Abstract
OBJECTIVES (1) To determine if the Health Plan Employer Data and Information Set (HEDIS) asthma inclusion criteria consistently identify persistent asthma on a year-to-year basis and (2) to explore whether variation in the number of years of qualification is associated with medication and resource utilization outcomes. STUDY DESIGN Retrospective observational study. METHODS We identified 132 414 patients in a large healthcare program who were included in 1 or more HEDIS persistent asthma cohorts between 1999 and 2002 and who had continuous insurance and pharmacy benefit coverage for the entire 4-year observation period. Medication, emergency department, and hospital use in 2002 was identified using electronic claims and pharmacy information. RESULTS Overall, 47.9% of the patients were identified as having persistent asthma in only 1 of 4 years, 40.8% had at least 2 consecutive years, and 28.2% had at least 3 consecutive years. In bivariate and multivariate analyses, more consecutive years of HEDIS persistent asthma qualification significantly increased the likelihood of frequent short-acting b-agonist use, inhaled antiinflammatory corticosteroid use, at least 1 emergency department visit, and at least 1 hospitalization. The strongest relationship was for 3 or more consecutive years of HEDIS qualification. CONCLUSIONS A significant portion of the HEDIS persistent asthma cohort does not qualify on a year-to-year basis, suggesting that the current 1-year qualification period or the underlying administrative case definition for persistent asthma may be suboptimal. Further clinical validation studies are needed to determine the optimal criteria for a more useful HEDIS persistent asthma case definition.

Abstract
OBJECTIVE To determine if differences between English- and Spanish-speaking parents in ratings of their children's health care can be explained by need for interpretive services. METHODS Using the Consumer Assessment of Health Plans Survey-Child-Survey (CAHPS), reports about provider communication were compared among 3 groups of parents enrolled in a Medicaid managed care health plan: 1) English speakers, 2) Spanish speakers with no self-reported need for interpretive services, and 3) Spanish speakers with self-reported need for interpretive services. Parents were asked to report how well their providers 1) listened carefully to what was being said, 2) explained things in a way that could be understood, 3) respected their comments and concerns, and 4) spent enough time during medical encounters. Multivariate logistic regression was used to compare the ratings of each of the 3 groups while controlling for child's gender, parent's gender, parent's educational attainment, child's health status, and survey year. RESULTS Spanish-speaking parents in need of interpretive services were less likely to report that providers spent enough time with their children (odds ratio = 0.34, 95% confidence interval = 0.17-0.68) compared to English-speaking parents. There was no statistically significant difference found between Spanish-speaking parents with no need of interpretive services and English-speaking parents. CONCLUSIONS Among Spanish- versus English-speaking parents, differences in ratings of whether providers spent enough time with children during medical encounters appear to be explained, in part, by need for interpretive services. No other differences in ratings of provider communication were found.

Abstract
OBJECTIVE We evaluated the effect of the Newborns' and Mothers' Health Protection Act on clinical and cost outcomes. METHODS We conducted an observational study of 18,023 healthy, mother-infant dyads before (n = 8670) and after (n = 9353) implementation of the Newborns' and Mothers' Health Protection Act legislation. Logistic regression was used to calculate adjusted odds ratios (ORs) for the following outcome measures: length of stay at least 48 hours, satisfaction with maternal length of stay, 7- and 30-day hospital readmission utilization, and 7- and 30-day emergency room utilization. Analysis of covariance was used to evaluate adjusted mean hospitalization costs per delivery. RESULTS Mothers in the postlegislation period were more likely to have hospital stays at least 48 hours (OR 3.99; 95% confidence interval [CI] 3.57, 4.44) and rate their length of stay as "about right" (OR 5.54; 95% CI 4.76, 6.46) compared with mothers in the prelegislation period. Neonates in the postlegislation period were more likely to have hospital stays of at least 48 hours (OR 3.96; 95% CI 3.54, 4.43) and less likely to be rehospitalized within 7 days after hospitalization (OR 0.61; 95% CI 0.40, 0.95) compared with neonates in the prelegislation period. Adjusted mean hospitalization costs increased $116 per delivery in the postlegislation period. CONCLUSIONS After implementation of the Newborns' and Mothers' Health Protection Act legislation, maternal and newborn length of stay and maternal satisfaction with length of stay increased substantially, and hospitalization costs increased significantly. The strongest clinical benefit was observed among neonates who were at a lower risk for hospitalization within 1 week of discharge. With the exception of 30-day emergency room utilization, there was insufficient statistical power to test for differences among other maternal clinical outcomes.

Abstract
This prospective cohort study compares 200 hospitalized, HIV-infected patients (Hispanic, African American, and white) from May 1992 to October 1998 to assess mortality (versus survival) over 75 months of follow-up. The relative risk of six-year mortality for each ethnic group is compared using Cox proportional hazards models after controlling for sociodemographic and clinical characteristics, access to general medical care, and HIV-specific treatment. The median survival of Hispanics (15.5 months) was significantly (p < 0.05) shorter than that of whites (23.8); survival for African Americans (35.1) did not differ from whites. In multivariate analysis, the adjusted relative risk of six-year mortality for Hispanics compared with whites was 2.14 (95 percent confidence interval = 1.26-3.66). The poor outcomes of Hispanics was not explained by access to general care or by HIV-specific treatment.

Abstract
Lack of timely HIV testing leads to missed prevention opportunities and poor prevention counselling may be related to further disease spread. We examined the association of self-reported access to medical care with receiving HIV testing and preventive counselling services among a sample of patients with HIV disease prior to hospitalization. We conducted a cross-sectional interview of 217 Los Angeles patients hospitalized with HIV-related illness between 1992 and 1993 and abstracted clinical data from the medical record. Eighty-four per cent of patients received HIV testing prior to hospitalization, but only 33% received preventive counselling services. Only 48% of all patients rated outpatient medical care as somewhat or very easy to obtain. Controlling for severity of illness, better access to outpatient medical care (OR = 1.48; 95% CI = 1.02-2.15), having a regular source of care (OR = 3.40; 95% CI = 1.29-8.97) and non-homosexual mode of HIV transmission (OR = 0.31; 0.12-0.83) were associated with receiving HIV testing services prior to hospitalization. Having a regular source of care (OR = 3.55; 95% CI = 1.37-9.22), being VA (Veterans' Administration) insured (OR = 6.16; 1.46-26.05), older age (OR = 0.95; 95% CI = 0.90-0.99) and having a CD4 count between 101-200 (OR = 0.19; 95% CI = 0.06-0.63) were associated with receiving HIV counselling. Limited self-reported access to medical care is associated with fewer patients receiving HIV testing and counselling. Improving timeliness of HIV testing may require removing the barriers to medical care.
