Glucose Self-monitoring in Non-Insulin-Treated Patients With Type 2 Diabetes in Primary Care Settings: A Randomized Trial.

Importance: The value of self-monitoring of blood glucose (SMBG) levels in patients with non-insulin-treated type 2 diabetes has been debated. Objective: To compare 3 approaches of SMBG for effects on hemoglobin A1c levels and health-related quality of life (HRQOL) among people with non-insulin-treated type 2 diabetes in primary care practice. Design, Setting, and Participants: The Monitor Trial study was a pragmatic, open-label randomized trial conducted in 15 primary care practices in central North Carolina. Participants were randomized between January 2014 and July 2015. Eligible patients with type 2 non-insulin-treated diabetes were: older than 30 years, established with a primary care physician at a participating practice, had glycemic control (hemoglobin A1c) levels higher than 6.5% but lower than 9.5% within the 6 months preceding screening, as obtained from the electronic medical record, and willing to comply with the results of random assignment into a study group. Of the 1032 assessed for eligibility, 450 were randomized. Interventions: No SMBG, once-daily SMBG, and once-daily SMBG with enhanced patient feedback including automatic tailored messages delivered via the meter. Main Outcomes and Measures: Coprimary outcomes included hemoglobin A1c levels and HRQOL at 52 weeks. Results: A total of 450 patients were randomized and 418 (92.9%) completed the final visit. There were no significant differences in hemoglobin A1c levels across all 3 groups (P = .74; estimated adjusted mean hemoglobin A1c difference, SMBG with messaging vs no SMBG, -0.09%; 95% CI, -0.31% to 0.14%; SMBG vs no SMBG, -0.05%; 95% CI, -0.27% to 0.17%). There were also no significant differences found in HRQOL. There were no notable differences in key adverse events including hypoglycemia frequency, health care utilization, or insulin initiation. Conclusions and Relevance: In patients with non-insulin-treated type 2 diabetes, we observed no clinically or statistically significant differences at 1 year in glycemic control or HRQOL between patients who performed SMBG compared with those who did not perform SMBG. The addition of this type of tailored feedback provided through messaging via a meter did not provide any advantage in glycemic control.

Three approaches to glucose monitoring in non-insulin treated diabetes: a pragmatic randomized clinical trial protocol.

BACKGROUND: For the nearly 75% of patients living with type 2 diabetes (T2DM) that do not use insulin, decisions regarding self-monitoring of blood glucose (SMBG) can be especially problematic. While in theory SMBG holds great promise for sparking favorable behavior change, it is a resource intensive activity without firmly established patient benefits. This study describes our study protocol to assess the impact of three different SMBG testing approaches on patient-centered outcomes in patients with non-insulin treated T2DM within a community-based, clinic setting. METHODS/DESIGN: Using stakeholder engagement approach, we developed and implemented a pragmatic trial of patient with non-insulin treated T2DM patients from five primary care practices randomized to one of three SMBG regimens: 1) no testing; 2) once daily testing with standard feedback consisting of glucose values being immediately reported to the patient through the glucose meter; and 3) once daily testing with enhanced patient feedback consisting of glucose values being immediately reported to the patient PLUS automated, tailored feedback messaging delivered to the patient through the glucose meter following each testing. Main outcomes assessed at 52 weeks include quality of life and glycemic control. DISCUSSION: This pragmatic trial seeks to better understand the value of SMBG in non-insulin treated patients with T2DM. This paper outlines the protocol used to implement this study in fifteen community-based primary care practices and highlights the impact of stakeholder involvement from the earliest stages of project conception and implementation. Plans for stakeholder involvement for result dissemination are also discussed. TRIAL REGISTRATION: ClinicalTrials.gov NCT02033499 , January 9, 2014.

Community Advisory Boards Guiding Engaged Research Efforts within a Clinical Translational Sciences Award: Key Contextual Factors Explored.

BACKGROUND: Engaging stakeholders in research carries the promise of enhancing the research relevance, transparency, and speed of getting findings into practice. By describing the context and functional aspects of stakeholder groups, like those working as community advisory boards (CABs), others can learn from these experiences and operationalize their own CABs. Our objective is to describe our experiences with diverse CABs affiliated with our community engagement group within our institution's Clinical Translational Sciences Award (CTSA). We identify key contextual elements that are important to administering CABs. METHODS: A group of investigators, staff, and community members engaged in a 6-month collaboration to describe their experiences of working with six research CABs. We identified the key contextual domains that illustrate how CABS are developed and sustained. Two lead authors, with experience with CABs and identifying contextual domains in other work, led a team of 13 through the process. Additionally, we devised a list of key tips to consider when devising CABs. RESULTS: The final domains include (1) aligned missions among stakeholders (2) resources/support, (3) defined operational processes/shared power, (4) well-described member roles, and (5) understanding and mitigating challenges. The tips are a set of actions that support the domains. CONCLUSIONS: Identifying key contextual domains was relatively easy, despite differences in the respective CAB's condition of focus, overall mission, or patient demographics represented. By contextualizing these five domains, other research and community partners can take an informed approach to move forward with CAB planning and engaged research.

The Cost to Successfully Apply for Level 3 Medical Home Recognition.

BACKGROUND: The National Committee for Quality Assurance patient-centered medical home recognition program provides practices an opportunity to implement medical home activities. Understanding the costs to apply for recognition may enable practices to plan their work. METHODS: Practice coaches identified 5 exemplar practices (3 pediatric and 2 family medicine practices) that received level 3 recognition. This analysis focuses on 4 that received recognition in 2011. Clinical, informatics, and administrative staff participated in 2- to 3-hour interviews. We determined the time required to develop, implement, and maintain required activities. We categorized costs as (1) nonpersonnel, (2) developmental, (3) those used to implement activities, (4) those used to maintain activities, (5) those to document the work, and (6) consultant costs. Only incremental costs were included and are presented as costs per full-time equivalent (pFTE) provider. RESULTS: Practice size ranged from 2.5 to 10.5 pFTE providers, and payer mixes ranged from 7% to 43% Medicaid. There was variation in the distribution of costs by activity by practice, but the costs to apply were remarkably similar ($11,453-15,977 pFTE provider). CONCLUSION: The costs to apply for 2011 recognition were noteworthy. Work to enhance care coordination and close loops were highly valued. Financial incentives were key motivators. Future efforts to minimize the burden of low-value activities could benefit practices.

Role of body temperature in diagnosing bacterial infection in nursing home residents.

OBJECTIVES: To provide empirically based recommendations for incorporating body temperature into clinical decision-making regarding diagnosing infection in nursing home (NH) residents. DESIGN: Retrospective. SETTING: Twelve North Carolina NHs. PARTICIPANTS: NH residents (N = 1,007) with 1,858 randomly selected antibiotic prescribing episodes. MEASUREMENTS: Maximum prescription-day temperature plus the three most recent nonillness temperatures were recorded for each prescribing episode. Two empirically based definitions of fever were developed: population-based (population mean nonillness temperature plus 2 population standard deviations (SDs)) and individualized (individual mean nonillness temperature plus 2 population SDs). These definitions were used along with previously published fever criteria and Infectious Diseases Society of America (IDSA) criteria to determine how often each prescribing episode was associated with a "fever" according to each definition. RESULTS: Mean population nonillness temperature was 97.7 ± 0.5 ºF. If "normal" were defined as less than 2 SDs above the mean, fever would be defined as any temperature above 98.7 ºF, and the previously published fever cutpoints and the IDSA criteria are 4.8 SDs above this mean. Between 30% and 32% of the 1,858 prescribing episodes examined were associated with temperatures more than 2 SDs above the population mean nonillness temperature, whereas only 10% to 11% of episodes met the previously published and IDSA fever definitions. CONCLUSION: Clinicians should apply empirically based definitions to assess fever in NH residents. Furthermore, low fever prevalence in residents treated with antibiotics according to all definitions suggests that some prescribing may not be associated with acute bacterial infection.

Antibiotic prescribing in 4 assisted-living communities: incidence and potential for improvement.

OBJECTIVE: To describe the prevalence, characteristics, and appropriateness of systemic antibiotic use in assisted living (AL) and to conduct a preliminary quality improvement intervention trial to reduce inappropriate prescribing. DESIGN: Pre-post study, with a 13-month intervention period. SETTING: Four AL communities. PARTICIPANTS: All prescribers, all AL staff who communicate with prescribers, and all patients who had an infection during the baseline and intervention periods. INTERVENTION: A standardized form for AL staff, an online education course and 5 practice briefs for prescribers, and monthly quality improvement meetings with AL staff. MEASUREMENTS: Monthly inventory of all systemic antibiotic prescriptions; interviews with the prescriber, AL staff member, closest family member, and patient (when capable) regarding 85 antibiotic prescribing episodes (30 baseline, 55 intervention), with data review by an expert panel to determine prescribing appropriateness. RESULTS: The mean number of systemic antibiotic prescriptions was 3.44 per 1,000 resident-days at baseline and 3.37 during the intervention, a nonsignificant change (P = .30). Few prescribers participated in online training. AL staff use of the standardized form gradually increased during the program. The proportion of prescriptions rated as probably inappropriate was 26% at baseline and 15% during the intervention, a nonsignificant trend (P = .25). Drug selection was largely appropriate during both time periods. CONCLUSIONS: AL antibiotic prescribing rates appear to be approximately one-half those seen in nursing homes, with up to a quarter being potentially inappropriate. Interventions to improve prescribing must reach all physicians and staff and most likely will require long time periods to have the optimal effect.

Costs and benefits of transforming primary care practices: a qualitative study of North Carolina's Improving Performance in Practice.

Primary care organizations must transform care delivery to realize the Institute for Healthcare Improvement's Triple Aim of better healthcare, better health, and lower healthcare costs. However, few studies have considered the financial implications for primary care practices engaged in transformation. In this qualitative, comparative case study, we examine the practice-level personnel and nonpersonnel costs and the benefits involved in transformational change among 12 primary care practices participating in North Carolina's Improving Performance in Practice (IPIP) program. We found average annual opportunity costs of $21,550 ($6,659 per full-time equivalent provider) for maintaining core IPIP activities (e.g., data management, form development and maintenance, meeting attendance). This average represents the cost of a 50% full-time equivalent registered nurse or licensed practical nurse. Practices were able to limit transformation costs by scheduling meetings during relatively slow patient care periods and by leveraging resources such as the assistance of IPIP practice coaches. Still, the costs of practice transformation were not trivial and would have been much higher in the absence of these efforts. Benefits of transformation included opportunities for enhanced revenue through reimbursement incentives and practice growth, improved efficiency and care quality, and maintenance of certification. Given the potentially high costs for some practices, policy makers may need to consider reimbursement and other strategies to help primary care practices manage the costs of practice redesign.

Successfully reducing antibiotic prescribing in nursing homes.

OBJECTIVES: To determine whether antibiotic prescribing can be reduced in nursing homes using a quality improvement (QI) program that involves providers, staff, residents, and families. DESIGN: A 9-month quasi-experimental trial of a QI program in 12 nursing homes (6 comparison, 6 intervention) conducted from March to November 2011. SETTING: Nursing homes in two regions of North Carolina, roughly half of whose residents received care from a single practice of long-term care providers. PARTICIPANTS: All residents, including 1,497 who were prescribed antibiotics. INTERVENTION: In the intervention sites, providers in the single practice and nursing home nurses received training related to prescribing guidelines, including situations for which antibiotics are generally not indicated, and nursing home residents and their families were sensitized to matters related to antibiotic prescribing. Feedback on prescribing was shared with providers and nursing home staff monthly. MEASUREMENTS: Rates of antibiotic prescribing for presumed urinary tract, skin and soft tissue, and respiratory infections. RESULTS: The QI program reduced the number of prescriptions ordered between baseline and follow-up more in intervention than in comparison nursing homes (adjusted incidence rate ratio = 0.86, 95% confidence interval = 0.79-0.95). Based on baseline prescribing rates of 12.95 prescriptions per 1,000 resident-days, this estimated adjusted incidence rate ratio implies 1.8 prescriptions avoided per 1,000 resident-days. CONCLUSION: This magnitude of effect is unusual in efforts to reduce antibiotic use in nursing homes. Outcomes could be attributed to the commitment of the providers; outreach to providers and staff; and a focus on common clinical situations in which antibiotics are generally not indicated; and suggest that similar results can be achieved on a wider scale if similar commitment is obtained and education provided.

Licensed nurse staffing and health service availability in residential care and assisted living.

OBJECTIVES: To create data-driven typologies of licensed nurse staffing and health services in residential care and assisted living (RC/AL). DESIGN: Cluster analysis was used to describe the patterns of licensed nurse staffing and 47 services and the extent to which these clusters were related. SETTING: RC/AL communities in the United States. PARTICIPANTS: A convenience sample of administrators and healthcare supervisors from 89 RC/AL communities in 22 states. MEASUREMENT: RC/AL characteristics, licensed nurse staffing (total number of hours that registered nurses (RNs) and licensed practical nurses (LPNs) worked), number of hours that contract nurses worked, and availability of 47 services. RESULTS: Analysis revealed four licensed nurse staffing clusters defined according to total number of hours and the type of nurse providing the hours (RN, LPN, or a mix of both). They ranged from no or minimal RN and LPN hours to high nursing hours with a mix of RNs and LPNs. The 47 services clustered into five clusters: basic services; technically complex services; assessments, wound care, and therapies; testing and specialty services; and gastrostomy and intravenous medications. The availability of services was related to the presence of nurses (RNs and LPNs) except for the gastrostomy and intravenous medication services, which were not readily available. CONCLUSION: The amount and skill mix of licensed nurse staffing varies in RC/AL and is related to the types of services available. These findings may have implications for resident care and outcomes. Future work in this area, including extension to include nonnurse direct care workers, is needed.

More extensive implementation of the chronic care model is associated with better lipid control in diabetes.

OBJECTIVE: Chronic disease collaboratives help practices redesign care delivery. The North Carolina Improving Performance in Practice program provides coaches to guide implementation of 4 key practice changes: registries, planned care templates, protocols, and self-management support. Coaches rate progress using the Key Drivers Implementation Scales (KDIS). This study examines whether higher KDIS scores are associated with improved diabetes outcomes. METHODS: We analyzed clinical and KDIS data from 42 practices. We modeled whether higher implementation scores at year 1 of participation were associated with improved diabetes measures during year 2. Improvement was defined as an increase in the proportion of patients with hemoglobin A1C values <9%, blood pressure values <130/80 mmHg, and low-density lipoprotein (LDL) levels <100 mg/dL. RESULTS: Statistically significant improvements in the proportion of patients who met the LDL threshold were noted with higher "registry" and "protocol" KDIS scores. For hemoglobin A1C and blood pressure values, none of the odds ratios were statistically significant. CONCLUSIONS: Practices that implement key changes may achieve improved patient outcomes in LDL control among their patients with diabetes. Our data confirm the importance of registry implementation and protocol use as key elements of improving patient care. The KDIS tool is a pragmatic option for measuring practice changes that are rooted in the Chronic Care Model.

Challenges of antibiotic prescribing for assisted living residents: perspectives of providers, staff, residents, and family members.

OBJECTIVES: To better understand the antibiotic prescribing process in assisted living (AL) communities given the growing rate of antibiotic resistance. DESIGN: Cross-sectional survey. SETTING: Four AL communities in North Carolina. PARTICIPANTS: Assisted living residents who received antibiotics (n = 30) from October 20, 2010, to March 31, 2011, a primary family member, staff, and the prescribing medical provider. MEASUREMENTS: Semistructured interviews that were conducted regarding prescribing included the information available at the time of prescribing and the perceptions of the quality of communication between providers, staff, residents and family members about the resident. Providers were asked an open-ended question regarding how to improve the communication process related to antibiotic prescribing for AL residents. RESULTS: For the 30 residents who received antibiotic prescriptions, providers often had limited information about the case and lacked familiarity with the residents, the residents' families, and staff. They also felt that cases were less severe and less likely to require an antibiotic than did residents, families, and staff. Providers identified several ways to improve the communication process, including better written documentation and staff and family presence. CONCLUSION: In a small sample of AL communities, providers faced an array of challenges in making antibiotic prescribing decisions. This work confirms the complex nature of antibiotic prescribing in AL communities and indicates that further work is needed to determine how to improve the appropriateness of antibiotic prescribing.

Does adherence to the Loeb minimum criteria reduce antibiotic prescribing rates in nursing homes?

OBJECTIVES: The Loeb minimum criteria (LMC), developed by a 2001 consensus conference, are minimum standards for initiation of antibiotics in long term care settings, intended to reduce inappropriate prescribing. This study examined the relationship between nursing home prescriber adherence to the LMC and antibiotic prescribing rates, overall and for each of three specific conditions (urinary tract infections, respiratory infections, and skin and soft tissue infections). DESIGN: We performed a cross-sectional analysis at the resident-day level. We estimated multivariate models adjusting for nursing home characteristics via multilevel Poisson regression, with robust standard errors to account for clustering of prescriptions within residents within nursing homes. SETTING: Data were collected through medical record abstraction in 12 North Carolina nursing homes between March and May 2011. PARTICIPANTS: In total, we identified 3381 antibiotic prescriptions across the 3-month observation period, representing 110,810 nursing home resident-days. In addition, we performed chart audits for a random sample of 653 prescriptions for urinary tract, respiratory, and skin and soft tissue infections to create measures of LMC adherence. MEASUREMENTS: The primary outcome was a count of prescriptions per resident per day, and the key explanatory variable was a nursing home-level estimate of the proportion of antibiotic prescriptions that adhered to the LMC. RESULTS: Only 12.7% of prescriptions were classified as LMC adherent, although there was substantial variation across study nursing homes (range: 4.8% to 22.0%) and by infection type (1.9% adherence for respiratory infections, 10.2% for urinary tract infections, and 42.7% for skin and soft tissue infections). We found no statistically significant relationship between adherence to the LMC and total prescribing rates (IRR 1.00, 95% CI 0.98-1.03; P = .84). Similarly, there was no significant relationship between LMC adherence and prescribing rates for treating urinary tract infections (IRR 0.99, 95% CI 0.96-1.02; P = .49), respiratory infections (IRR 0.91, 95% CI 0.76-1.08; P = .28), or skin and soft tissue infections (IRR 0.99, 95% CI 0.98-1.01; P = .39) considered alone. CONCLUSION: We found little evidence that prescribers in study nursing homes considered the LMC when making prescribing decisions. Further, we found no evidence that greater adherence to the LMC was associated with lower rates of antibiotic prescribing. Evidence-based guidelines for antibiotic initiation must be adopted more widely before any substantial gains from adherence are likely to be recognized.

Physician perspectives on medical care delivery in assisted living.

OBJECTIVES: To describe the provision of medical care in assisted living (AL) as provided by physicians who are especially active in providing care to older adults and AL residents; to identify characteristics associated with physician confidence in AL staff; and to ask physicians a variety of questions about their experience providing care to AL residents and how it compares with providing care in the nursing home and home care settings. DESIGN: Cross-sectional descriptive study. SETTING: AL communities in 27 states. PARTICIPANTS: One hundred sixty-five physicians and administrators of 125 AL settings in which they had patients. MEASUREMENTS: Interviews and questionnaires containing open- and close-ended questions regarding demographics, care arrangements, attitudes, and behaviors in managing medical problems. RESULTS: Most respondents were certified in internal medicine (46%) or family medicine (47%); 32% were certified in geriatrics and 30% in medical directorship. In this select sample, 48% visited the AL setting once a year or less, and 19% visited once a week or more. Mean physician confidence in AL staff was 3.3 (somewhat confident), with greater confidence associated with smaller AL community size, nursing presence, and the physician being the medical director. Qualitative analyses identified differences between settings including lack of vital sign assessment in the home setting, concern about the ability of AL staff to assess and monitor problems, and greater administrative and regulatory requirements in AL than in the other settings. CONCLUSION: Providing medical care for AL residents presents unique challenges and opportunities for physicians. Nursing presence and physician oversight and familiarity and communicating with AL staff who are highly familiar with a given resident and can monitor care may facilitate care.

Do clinicians tell patients they have prehypertension?

BACKGROUND: the clinical utility of the prehypertension label is questionable. We sought to estimate how often patients with prehypertension are being told about it by their primary care clinicians. METHODS: we conducted a cross-sectional study of adult patients visiting practices within the North Carolina Family Medicine Research Network in summer 2008. Non-hypertensive patients were asked whether a doctor or other health care provider had ever told them they had "prehypertension"; a subsample of patients with measured blood pressure (BP) in the prehypertension range was asked the same question. RESULTS: of 1008 non-hypertensive patients, 1.9% indicated being told they had prehypertension. Among a subsample of 102 patients with measured BP in the prehypertension range, 2.0% indicated being told they had prehypertension. CONCLUSION: few patients who probably have prehypertension are being told about it by clinicians.

Patient perceptions of mistakes in ambulatory care.

BACKGROUND: Little information exists about current patient perceptions of medical mistakes in ambulatory care within a diverse population. We aimed to learn about the perceptions of medical mistakes, what factors were associated with perceived mistakes, and whether the participants changed physicians because of these perceived mistakes. METHODS: We conducted a cross-sectional survey at 7 primary care practices in North Carolina of English- or Spanish-speaking adults, aged 18 years and older, who saw a health care professional during 2008. Main outcome measures were 4 questions about patient perceptions of medical mistakes in the ambulatory care setting, including (1) overall experience with a medical mistake; type of mistake, such as a (2) diagnostic mistake or (3) treatment mistake, and its associated harm; and (4) effect of this mistake on changing physicians. RESULTS: Of 1697 participants, 265 (15.6%) responded that a physician had made a mistake, 227 (13.4%) reported a wrong diagnosis, 212 (12.5%) reported a wrong treatment, and 239 (14.1%) reported having changed physicians because of a mistake. Participants perceived mistakes and harm in both diagnostic care and medical treatment. Patients with chronic back pain, higher educational attainment, and poor physical health were at increased odds of perceiving mistakes, whereas African American patients were less likely to perceive mistakes. CONCLUSIONS: Patients perceived mistakes in their diagnostic and treatment care in the ambulatory setting. These perceptions had a concrete effect on the physician-patient relationship, often leading patients to seek another health care professional.

Perceptions of informed decision making about cancer screening in a diverse primary care population.

OBJECTIVE: Our objective was to describe primary care patients' perceptions of informed and shared decision making about cancer screening tests in a diverse sample. METHODS: We administered a 33-item survey to 467 women and 257 men aged 50 years and older from seven practices in a family medicine practice-based research network. We used ordered logistic regression to assess the relationship between gender, race, education, marital status, and self-rated health with measures of patient-centered care relating to cancer screening tests, controlling for practice site. RESULTS: Men had greater odds than women of reporting they did not know the benefits of cancer screening (1.46, 95% CI=1.08, 1.99). Compared to white respondents, black respondents reported greater odds of not knowing the benefits (1.70, 95% CI=1.23, 2.36) and risks (1.38, 95% CI=1.00, 1.90) of cancer screening, of not making informed choices (1.50, 95% CI=1.09, 2.07), and that their doctor did not give them some control over their cancer screening tests (1.57, 95% CI=1.12, 2.20). Low education level was also associated with lower perceptions of informed decision making. CONCLUSIONS: Patients with male sex, non-white race, and low education level reported more uncertainty about cancer screening tests and less patient-centered care.

Impact of ambient bright light on agitation in dementia.

OBJECTIVE: To evaluate the effect of ambient bright light therapy (BLT) on agitation among institutionalized persons with dementia. METHODS: High intensity, low glare ambient lighting was installed in activity and dining areas of a state psychiatric hospital unit in North Carolina and a dementia-specific residential care facility in Oregon. The study employed a cluster-unit crossover design involving four ambient lighting conditions: AM bright light, PM bright light, All Day bright light, and Standard light. Sixty-six older persons with dementia participated. Outcome measures included direct observation by research personnel and completion by staff caregivers of the 14-item, short form of the Cohen-Mansfield Agitation Inventory (CMAI). RESULTS: Analyses of observational data revealed that for participants with mild/moderate dementia, agitation was higher under AM light (p = 0.003), PM light (p < 0.001), and All Day light (p = 0.001) than Standard light. There was also a trend toward severely demented participants being more agitated during AM light than Standard light (p = 0.053). Analysis of CMAI data identified differing responses by site: the North Carolina site significantly increased agitation under AM light (p = 0.002) and PM light (p = 0.013) compared with All Day light while in Oregon, agitation was higher for All Day light compared to AM light (p = 0.030). In no comparison was agitation significantly lower under any therapeutic condition, in comparison to Standard lighting. CONCLUSIONS: Ambient bright light is not effective in reducing agitation in dementia and may exacerbate this behavioral symptom.

Hypertensive patients' use of blood pressure monitors stationed in pharmacies and other locations: a cross-sectional mail survey.

BACKGROUND: Blood pressure (BP) monitors are commonly stationed in public places such as pharmacies, but it is uncertain how many people with hypertension currently use them. We sought to estimate the proportion of hypertensive patients who use these types of monitors and examine whether use varies by demographic or health characteristics. METHODS: We conducted a cross-sectional mail survey of hypertensive adults enrolled in a practice based research network of 24 primary care practices throughout the state of North Carolina. We analyzed results using descriptive statistics and examined bivariate associations using chi-square and independent associations using logistic regression. RESULTS: We received 530 questionnaires (76% response rate). Of 333 respondents (63%) who reported checking their BP in locations other than their doctor's office or home, 66% reported using a monitor stationed in a pharmacy. Younger patients more commonly reported using pharmacy monitors (48% among those < 45 years vs 35% of those over 65, p = 0.04). Blacks reported using them more commonly than whites (48% vs 39%, p = 0.03); and high school graduates more often than those with at least some college (50% vs 37%, p = 0.02). In multivariate analysis, younger age (aOR 1.49; 95% CI 1.00-2.21 for those age 45 to 65 years vs those > 65 years old) and high school education (aOR 1.74; 95% CI 1.13-2.58) were associated with use of pharmacy-stationed monitors, but Black race was not. Patients with diabetes, heart disease, or stroke were not more likely to use pharmacy-stationed monitors. CONCLUSION: Hypertensive patients' use of BP monitors located in pharmacies is common. Younger patients, Blacks, and those with high school education were slightly more likely to report using them. Because use of these monitors is so common, efforts to ensure their accuracy are important.

High blood pressure knowledge among primary care patients with known hypertension: a North Carolina Family Medicine Research Network (NC-FM-RN) study.

BACKGROUND: We sought to assess primary care patients' current knowledge about various aspects of high blood pressure (BP). METHODS: We mailed a questionnaire to 700 hypertensive patients enrolled in a practice-based research network cohort from 24 practices in North Carolina. We determined percentages of respondents (total and by subgroups) incorrectly answering each of 6 questions pertaining to various aspects of high BP. We then examined bivariate and multivariate associations with answering 2 or more items incorrectly ("lower hypertension knowledge"). RESULTS: We received 530 completed surveys (76% response rate). Twenty-six percent (95% CI, 22-30) of respondents did not know that most of the time people with high BP do not feel it. Twenty-two percent (95% CI, 18-26) either were not sure whether anything could be done to prevent high BP or believe that there is nothing that can be done. Nineteen percent (95% CI, 16-22) either believe taking medications will cure high BP or are not sure whether it will. Twenty-two percent (95% CI, 19-26) of respondents had overall lower hypertension knowledge. Independent associations with lower hypertension knowledge were African-American race (odds ratio, 1.77; 95% CI, 1.10-2.86), having less than high school education (odds ratio, 2.43; 95% CI, 1.34-4.41), and history of stroke/mini-stroke (odds ratio, 1.94; 95% CI, 1.00-3.75). CONCLUSIONS: Patients may need to be taught the difference between curing hypertension and treating it with medications. Efforts to educate the public that lifestyle modifications can prevent hypertension and that it usually causes no symptoms need to continue. It seems especially important to develop messages that reach African-Americans and people with less education.
