RESUMO
PURPOSE OF REVIEW: We review studies published since 2014 that examined team-based care strategies and involved pharmacists to improve blood pressure (BP). We then discuss opportunities and challenges to sustainment of team-based care models in primary care clinics. RECENT FINDINGS: Multiple studies presented in this review have demonstrated that team-based care including pharmacists can improve BP management. Studies highlighted the cost-effectiveness of a team-based pharmacy intervention for BP control in primary care clinics. Little information was found on factors influencing sustainability of team-based care interventions to improve BP control. Future work is needed to determine the best populations to target with team-based BP programs and how to implement team-based approaches utilizing pharmacists in diverse clinical settings. Future studies need to not only identify unmet clinical needs but also address reimbursement issues and stakeholder engagement that may impact sustainment of team-based care interventions.

BACKGROUND: Selection bias and non-participation bias are major methodological concerns which impact external validity. Cluster-randomized controlled trials are especially prone to selection bias as it is impractical to blind clusters to their allocation into intervention or control. This study assessed the impact of selection bias in a large cluster-randomized controlled trial. METHODS: The Improved Cardiovascular Risk Reduction to Enhance Rural Primary Care (ICARE) study examined the impact of a remote pharmacist-led intervention in twelve medical offices. To assess eligibility, a standardized form containing patient demographics and medical information was completed for each screened patient. Eligible patients were approached by the study coordinator for recruitment. Both the study coordinator and the patient were aware of the site's allocation prior to consent. Patients who consented or declined to participate were compared across control and intervention arms for differing characteristics. Statistical significance was determined using a two-tailed, equal variance t-test and a chi-square test with adjusted Bonferroni p-values. Results were adjusted for random cluster variation. RESULTS: There were 2749 completed screening forms returned to research staff with 461 subjects who had either consented or declined participation. Patients with poorly controlled diabetes were found to be significantly more likely to decline participation in intervention sites compared to those in control sites. A higher mean diastolic blood pressure was seen in patients with uncontrolled hypertension who declined in the control sites compared to those who declined in the intervention sites. However, these findings were no longer significant after adjustment for random variation among the sites. After this adjustment, females were now found to be significantly more likely to consent than males (odds ratio = 1.41; 95% confidence interval = 1.03, 1.92). CONCLUSIONS: Though there appeared to be a higher consent rate for females than for males, the overall impact of potential selection bias and refusal to participate was minimal. Without rigorous methodology, selection bias may be a threat to external validity in cluster-randomized trials. TRIAL REGISTRATION: NCT01983813 . Date of registration: Oct. 28, 2013.

BACKGROUND: Pharmacists may improve medication-related outcomes during transitions of care. The aim of the Iowa Continuity of Care Study was to determine if a pharmacist case manager (PCM) providing a faxed discharge medication care plan from a tertiary care institution to primary care could improve medication appropriateness and reduce adverse events, rehospitalization and emergency department visits. METHODS: Design. Randomized, controlled trial of 945 participants assigned to enhanced, minimal and usual care groups conducted 2007 to 2012. Subjects. Participants with cardiovascular-related conditions and/or asthma or chronic obstructive pulmonary disease were recruited from the University of Iowa Hospital and Clinics following admission to general medicine, family medicine, cardiology or orthopedics. Intervention. The minimal group received admission history, medication reconciliation, patient education, discharge medication list and medication recommendations to inpatient team. The enhanced group also received a faxed medication care plan to their community physician and pharmacy and telephone call 3-5 days post-discharge. Participants were followed for 90 days post-discharge. Main Outcomes and Measures. Medication appropriateness index (MAI), adverse events, adverse drug events and post-discharge healthcare utilization were compared by study group using linear and logistic regression, as models accommodating random effects due to pharmacists indicated little clustering. RESULTS: Study groups were similar at baseline and the intervention fidelity was high. There were no statistically significant differences by study group in medication appropriateness, adverse events or adverse drug events at discharge, 30-day and 90-day post-discharge. The average MAI per medication as 0.53 at discharge and increased to 0.75 at 90 days, and this was true across all study groups. Post-discharge, about 16% of all participants experienced an adverse event, and this did not differ by study group (p > 0.05). Almost one-third of all participants had any type of healthcare utilization within 30 days post-discharge, where 15% of all participants had a 30-day readmission. Healthcare utilization post-discharge was not statistically significant different at 30 or 90 days by study group. CONCLUSION: The pharmacist case manager did not affect medication use outcomes post-discharge perhaps because quality of care measures were high in all study groups.

Hypertension is the most common condition seen in primary care and leads to myocardial infarction, stroke, renal failure, and death if not detected early and treated appropriately. Patients want to be assured that blood pressure (BP) treatment will reduce their disease burden, while clinicians want guidance on hypertension management using the best scientific evidence. This report takes a rigorous, evidence-based approach to recommend treatment thresholds, goals, and medications in the management of hypertension in adults. Evidence was drawn from randomized controlled trials, which represent the gold standard for determining efficacy and effectiveness. Evidence quality and recommendations were graded based on their effect on important outcomes. There is strong evidence to support treating hypertensive persons aged 60 years or older to a BP goal of less than 150/90 mm Hg and hypertensive persons 30 through 59 years of age to a diastolic goal of less than 90 mm Hg; however, there is insufficient evidence in hypertensive persons younger than 60 years for a systolic goal, or in those younger than 30 years for a diastolic goal, so the panel recommends a BP of less than 140/90 mm Hg for those groups based on expert opinion. The same thresholds and goals are recommended for hypertensive adults with diabetes or nondiabetic chronic kidney disease (CKD) as for the general hypertensive population younger than 60 years. There is moderate evidence to support initiating drug treatment with an angiotensin-converting enzyme inhibitor, angiotensin receptor blocker, calcium channel blocker, or thiazide-type diuretic in the nonblack hypertensive population, including those with diabetes. In the black hypertensive population, including those with diabetes, a calcium channel blocker or thiazide-type diuretic is recommended as initial therapy. There is moderate evidence to support initial or add-on antihypertensive therapy with an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker in persons with CKD to improve kidney outcomes. Although this guideline provides evidence-based recommendations for the management of high BP and should meet the clinical needs of most patients, these recommendations are not a substitute for clinical judgment, and decisions about care must carefully consider and incorporate the clinical characteristics and circumstances of each individual patient.

PURPOSE OF REVIEW: Inadequately controlled blood pressure is considered an important risk factor for both chronic kidney disease (CKD) progression and cardiovascular disease progression in CKD patients. Patients with CKD and hypertension are typically followed in primary care practice settings and blood pressure is not controlled in a sizeable proportion. This review will focus on the evidence which demonstrates the important role of the pharmacist in collaboration with physicians within primary care practices to improve blood pressure management in CKD patients. RECENT FINDINGS: Several lines of evidence show that pharmacists working in collaboration with primary care physicians can improve blood pressure management as compared with usual care with a physician alone. The major effects of pharmacist intervention are to intensify antihypertensive regimens and improve medication adherence. SUMMARY: Currently, hypertension is not well controlled in a significant proportion of individuals with CKD. Recent studies in the CKD population support evidence from the general population that pharmacists as part of the collaborative care team improves blood pressure management. Research is needed to demonstrate cost-effectiveness of collaborative care models in management of hypertension and other comorbid conditions in CKD patients.

More than 50% of Americans possess at least one chronic condition and another 25% suffer from two or more, leaving primary care teams tasked to care for the chronic, acute, and preventive care needs of their large patient panels. Pharmacists can reduce the burden on busy providers by effectively managing chronic diseases as members of health care teams. Many private physician practices lack the resources to include pharmacists on their teams. A centralized, remote clinical pharmacy services model allows pharmacists to remotely manage chronic disease in patients in collaboration with primary care providers. The purpose of this report is to describe how a centralized, remote clinical pharmacy team was developed, trained, and effectively integrated into multiple, diverse primary care settings across the U.S.

Background: We developed a remote cardiovascular risk service (CVRS) managed by clinical pharmacists to support primary care teams. The purpose of this study was to examine whether the CVRS could improve guideline adherence in primary care clinics with diverse geographic and patient characteristics. Methods: This study was a cluster-randomized trial initiated in 20 primary care clinics across the US. Clinics were stratified as high or low minority and then randomized to receive the intervention or maintain usual care for 12 months. The primary outcome was adherence to relevant The Guideline Advantage (TGA) criteria met. TGA is a compilation of criteria from practice guidelines intended to improve the quality of primary care. Post-hoc outcomes included changes in individual TGA measures. Results: A total of 401 study subjects were included in the analysis. Mean TGA scores remained the same in the intervention group (n=193, 0.72) and slightly decreased in the usual care group (n=208, 0.67 to 0.66) over the 12-month study period. There was no significant difference between the mean TGA scores in intervention and usual care groups for the overall population at 12 months (0.72 versus 0.66 respectively, p=0.10). For under-represented minority subjects, there was no significant difference between TGA scores at 12 months (n=186; 0.70 versus 0.67, respectively, p=0.50). In a post-hoc analysis of subjects uncontrolled at baseline, there was a significant improvement in systolic BP at 12 months in the intervention group versus usual care (model-based difference of -8.03mmHg, p=0.03). Conclusions: Improvements in individual TGA measures were limited, in part, due to higher than expected baseline TGA scores. Future studies of this model should focus on patients with uncontrolled conditions at high risk for cardiovascular events.

RESUMO
BACKGROUND: Medical clinics are increasingly hiring clinical pharmacists to improve management of cardiovascular disease (CVD). However, the limited number of clinical pharmacists employed in a clinic may not impact the large number of complex patients needing the services. We have developed a remote telehealth service provided by clinical pharmacists to complement CVD services provided by on-site clinical pharmacists and aid sites without a clinical pharmacist. This cardiovascular risk service (CVRS) has been studied in two NIH-funded trials, however, we identified barriers to optimal intervention implementation. The purpose of this study is to examine how to implement the CVRS into medical offices and see if the intervention will be sustained. METHODS: This is a 5-year, pragmatic, cluster-randomized clinical trial in 13 primary care clinics across the US. We randomized clinics to receive CVRS or usual care and will enroll 325 patient subjects and 288 key stakeholder subjects. We have obtained access to the electronic medical records (EMRs) of all study clinics to recruit subjects and provide the pharmacist intervention. The intervention is staggered so that after 12 months, the usual care sites will receive the intervention for 12 months. Follow-up will be accomplished though medical record abstraction at baseline, 12 months, 24 months, and 36 months. CONCLUSIONS: This study will enroll subjects through 2021 and results will be available in 2024. This study will provide unique information on how the CVRS provided by remote clinical pharmacists can be effectively implemented in medical offices, many of which already employ on-site clinical pharmacists.

BACKGROUND: Uncontrolled or undiagnosed hypertension (HTN) is estimated to be as high as 46% in emergency departments (EDs). Uncontrolled HTN contributes significantly to cardiovascular morbidity and disproportionately affects communities of color. EDs serve high risk populations with uncontrolled conditions that are often missed by other clinical settings and effective interventions for uncontrolled HTN in the ED are critically needed. The ED is well situated to decrease the disparities in HTN control by providing a streamlined intervention to high risk populations that may use the ED as their primary care. METHODS: Targeting of UnControlled Hypertension in the Emergency Department (TOUCHED), is a two-arm single site randomized controlled trial of 770 adults aged 18-75 presenting to the ED with uncontrolled HTN comparing (1) usual care, versus (2) an Educational and Empowerment (E2) intervention that integrates a Post-Acute Care Hypertension Consultation (PACHT-c) with a mobile health BP self-monitoring kit. The primary outcome is differences in mean systolic blood pressure (SBP) at 6-months post enrollment. Secondary outcomes include differences in mean SBP and mean diastolic BP (DBP) at 3-months and mean DBP at 6-months. Additionally, improvement in cardiovascular risk score, medication adherence, primary care engagement, and HTN knowledge will also be assessed as part of this study. CONCLUSIONS: The TOUCHED trial will be instrumental in determining the effectiveness of a brief ED-based intervention that is portable to other urban EDs with high-risk populations.

BACKGROUND: Past work suggests that the degree of similarity between patient and physician attitudes may be an important predictor of patient-centered outcomes. OBJECTIVE: To examine the extent to which patient and provider symmetry in health locus of control (HLOC) beliefs was associated with objectively derived medication refill adherence in patients with co-morbid diabetes mellitus (DM) and hypertension (HTN). PARTICIPANTS: Eighteen primary care physicians at the VA Iowa City Medical Center and affiliated clinics; 246 patients of consented providers with co-morbid DM and HTN. DESIGN: Established patient-physician dyads were classified into three groups according to the similarity of their HLOC scores (assessed in parallel). Data analysis utilized hierarchical linear modeling (HLM) to account for clustering of patients within physicians. MAIN MEASURES: Objectively derived medication refill adherence was computed using data from the VA electronic pharmacy record; blood pressure and HgA1c values were considered as secondary outcomes. KEY RESULTS: Physician-patient dyads holding highly similar beliefs regarding the degree of personal control that individual patients have over health outcomes showed significantly higher overall and cardiovascular medication regimen adherence (p = 0.03) and lower diastolic blood pressure (p = 0.02) than in dyads in which the patient held a stronger belief in their own personal control than did their treating physician. Dyads in which patients held a weaker belief in their own personal control than did their treating physician did not differ significantly from symmetrical dyads. The same pattern was observed after adjustment for age, physician sex, and physician years of practice. CONCLUSIONS: These data are the first to demonstrate the importance of attitudinal symmetry on an objective measure of medication adherence and suggest that a brief assessment of patient HLOC may be useful for tailoring the provider's approach in the clinical encounter or for matching patients to physicians with similar attitudes towards care.

OBJECTIVES: To examine the effect of a patient activation intervention with financial incentives to promote switching to a thiazide in patients with controlled hypertension using calcium channel blockers (CCBs). STUDY DESIGN: The Veterans Affairs Project to Implement Diuretics, a randomized clinical trial, was conducted at 13 Veterans Affairs primary care clinics. METHODS: Patients (n = 236) with hypertension previously controlled using CCBs were randomized to a control group (n = 90) or 1 of 3 intervention groups designed to activate patients to talk with their primary care providers about switching to thiazides: Group A (n = 53) received an activation letter, group B (n = 42) received a letter plus a financial incentive to discuss switching from a CCB to a thiazide, and group C (n = 51) received a letter, a financial incentive, and a telephone call encouraging patients to speak with their primary care providers. The primary outcome was thiazide prescribing at the index visit. RESULTS: At the index visit, the rate of switching to a thiazide was 1.1% in the control group and 9.4% (group A), 26.2% (group B), and 31.4% (group C) for the intervention groups (P < .0001). In adjusted analysis, patients randomized to group C were significantly more likely to switch from a CCB to thiazide at the index visit (odds ratio, 4.14; 95% CI, 1.45-11.84; P < .01). CONCLUSIONS: This low-cost, low-intensity patient activation intervention resulted in increased rates of switching to a thiazide in those whose hypertension was controlled using another medication, suggesting that such interventions may be used to overcome medication optimization challenges, including clinical inertia.

Hydroxychloroquine combined with azithromycin has been investigated for activity against coronavirus disease 2019 (COVID-19), but concerns about adverse cardiovascular (CV) effects have been raised. This study evaluated claims data to determine if risks for CV events were increased with hydroxychloroquine alone or combined with azithromycin. We identified data from 43,752 enrollees that qualified for analysis. The number of CV events increased by 25 (95% confidence interval [CI]: 8, 42, p=0.005) per 1000 people per year of treatment with hydroxychloroquine alone compared with pretreatment levels and by 201 (95% CI: 145, 256, p<0.001) events per 1000 people per year when individuals took hydroxychloroquine and azithromycin. These rates translate to an additional 0.34 (95% CI: 0.11, 0.58) CV events per 1000 patients placed on a 5-day treatment with hydroxychloroquine monotherapy and 2.75 (95% CI: 1.99, 3.51) per 1000 patients on a 5-day treatment with both hydroxychloroquine and azithromycin. The rate of adverse events increased with age following exposure to hydroxychloroquine alone and combined with azithromycin. For females aged 60 to 79 years prescribed hydroxychloroquine, the rate of adverse CV events was 0.92 per 1000 patients on 5 days of therapy, but it increased to 4.78 per 1000 patients when azithromycin was added. The rate of adverse CV events did not differ significantly from zero for patients 60 years of age or younger. These data suggest that hydroxychloroquine with or without azithromycin is likely safe in individuals under 60 years of age if they do not have additional CV risks. However, the combination of hydroxychloroquine and azithromycin should be used with extreme caution in older patients.

BACKGROUND: New approaches are needed to better monitor blood pressure (BP) between physician visits, especially for patients in rural areas or for those who lack transportation. We have developed a custom-built bi-directional texting platform for home BP measurements that can then be managed by clinical pharmacists located remotely. The purpose of this study is to evaluate whether the BP texting approach combined with a pharmacist-based intervention improves BP management and to determine if the approach is cost effective. METHODS: This study is a randomized, prospective trial in four primary care offices that serve patients in rural areas. Subjects will receive standardized research BP measurements at baseline, 6 and 12 months. The primary outcome will be differences between the intervention and control group in mean systolic BP at 12 months. Secondary outcomes will include systolic BP at 6 months; diastolic BP at 6 and 12 months, number of medication changes and costs. CONCLUSIONS: This study plans to enroll subjects through 2022, follow-up will be completed in 2023 and results will be available in 2024. This study will provide information on whether a combined approach using texting of home BP values and a pharmacist-based telehealth services can improve BP control.

OBJECTIVES: Individuals in rural areas face critical health disparities, including limited access to mental healthcare services and elevated burden of chronic illnesses. While disease outcomes are often worse in individuals who have both physical and mental comorbidities, few studies have examined rural, chronically-ill older adults' experiences accessing mental health services. The aim of the study was to determine barriers to finding, receiving and adhering to mental health treatments in this population to inform future interventions delivering services. DESIGN: We conducted a qualitative study of barriers and facilitators to mental healthcare access. 19 interviews were analysed deductively for barriers using a modified version of Penchansky and Thomas's theory of access as an analytical framework. SETTING: This study was conducted remotely using telephonic interviews. Patients were located in various rural Iowa towns and cities. PARTICIPANTS: 15 rural Iowan older adults with multiple physical comorbidities as well as anxiety and/or depression. RESULTS: We found that while patients in this study often felt that their mental health was important to address, they experienced multiple, but overlapping, barriers to services that delayed care or broke their continuity of receiving care, including limited knowledge of extant services and how to find them, difficulties obtaining referrals and unsatisfactory relationships with mental health service providers. CONCLUSIONS: Our findings indicate that intervention across multiple domains of access is necessary for successful long-term management of mental health disorders for patients with multiple chronic comorbidities in Iowa.

The authors examined whether using home BP measurements collected via a custom-built bi-directional-texting platform incorporated into patients' electronic medical records would lead to treatment calibration and improved BP management. Patients were randomized to either the intervention group and collected home measurements based on reminders and reported via bi-directional texting, or to the control group, with home BP measurement reporting via standard practice (eg, phone, electronic medical record portal) and instructed to return 7 morning and 7 evening BP measurements. Outcomes included number of BP measurements submitted, the number of medication changes, reduction in BP, and BP control. 72% of the intervention group submitted at least 14 readings, compared with 45% of the control group. BP control improved in both groups. However, the authors found no statistically significant difference in BP or the number of BP-medication changes at 1, 3, or 6 months compared with the control group.

STUDY OBJECTIVES: To evaluate trends in adverse symptoms as blood pressure becomes controlled, and to determine if these symptoms are influenced by social support and self-efficacy. DESIGN: Secondary analysis from a randomized controlled study of physician-pharmacist collaboration to improve blood pressure control. SETTING: Five university-affiliated primary care clinics. PATIENTS: A total of 179 patients (aged 21-85 yrs) with uncontrolled primary hypertension who were taking no antihypertensive drugs or up to three antihypertensive drugs at baseline were randomized to the intervention group, in which pharmacists were involved in their care, or to the control group, who received usual care from their physicians. Of these patients, 160 completed the study: 92 were in the intervention group, and 68 were in the control group. INTERVENTION: In both groups, patient-reported symptoms suggestive of adverse drug reactions (ADRs) were recorded at each study visit with use of a structured ADR questionnaire. Social support and self-efficacy questionnaires were also administered at each study visit. MEASUREMENTS AND MAIN RESULTS: Patients' ADR scores decreased significantly from baseline to the end of the study in both the control (from a mean of 26.5 to 18.4) and intervention (from 29.9 to 22.7) groups (p<0.0001 for both comparisons), although no significant difference was noted between groups. The mean +/- SD number of antihypertensive drugs/patient increased in both the intervention (from 1.5 +/- 1.0 to 2.4 +/- 0.9 drugs) and control (from 1.4 +/- 1.0 to 1.9 +/- 1.0 drugs) groups; however, the difference between groups was significant only at the end of the study. Additional analyses were performed on self-efficacy and social support to determine a potential reason for the reduction in ADR scores despite an increase in drug use. Improvements in self-efficacy and social support scores were significantly and independently associated with improvement in ADR score (p<0.05). CONCLUSIONS: In both groups, ADR scores improved despite an increase in antihypertensive drug use. Improvements in social support and, to a lesser extent, self-efficacy were associated with improvements in ADR scores. Patients should not expect an increase in distressful symptoms as their blood pressure becomes controlled with antihypertensive drugs, especially when adequate social support is available.

STUDY OBJECTIVE: To compare physician adherence to guidelines from the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure for patients younger than 65 years of age with those aged 65 years and older, and to analyze whether factor groupings (subsets of criteria used to determine adherence) were predictive of blood pressure control. DESIGN: Retrospective medical record review. SETTING: Five university-affiliated family medicine and internal medicine outpatient clinics. PATIENTS: One hundred seventy-nine patients (age range 21-85 yrs) with uncontrolled hypertension: 105 patients were younger than 65 years (nonsenior), and 74 patients were 65 years or older (senior). MEASUREMENTS AND MAIN RESULTS: Data abstracted from each patient's medical record were used to evaluate adherence to 17 process-of-care criteria, identified to assess physician adherence to the guidelines. A computer algorithm generated scores for each criterion as well as an overall adherence score. The relationship between the adherence score and blood pressure control was then examined. Separate factor analyses were conducted to ascertain differences in the way that the criteria were grouped. Factor scores were calculated for each patient, and the scores were evaluated in the context of blood pressure control. Guideline adherence scores were significantly higher for nonsenior patients than for senior patients (59.3% vs 56.1%, p=0.024). Blood pressure control rate was also higher, although not significantly, in nonseniors versus seniors (68.6% vs 56.8%, p=0.063). No factors in the senior group were significantly associated with blood pressure control, but one was significantly correlated in the nonsenior group (p<0.0001). It included diuretic therapy, adjusting a drug when a patient's blood pressure was uncontrolled, documentation of uncontrolled blood pressure in the medical record at the visit, documentation of the correct blood pressure goal, documentation of cardiovascular risk factors, and measurement of urine albumin level. CONCLUSION: Overall physician adherence to blood pressure guidelines was significantly higher for the nonsenior group than for the senior group. Similarly, control of blood pressure was better in the nonsenior group. However, no significant relationship between overall adherence scores and blood pressure control was found in either group. In nonseniors, one factor grouping was significantly correlated with blood pressure control. Future studies should evaluate the process-of-care criteria to determine if and how they are related to blood pressure control in senior patients.

STUDY OBJECTIVE: To examine the influence of specific patient characteristics on the success of ambulatory blood pressure monitoring (ABPM). DESIGN: Retrospective analysis. SETTING: University-affiliated family care center. PATIENTS: Five hundred thirty patients (mean age 52.7 yrs, range 14-90 yrs) who were undergoing ABPM between January 1, 2001, and July 1, 2007. MEASUREMENT AND MAIN RESULTS: Specific patient characteristics were identified through an electronic medical record review and then examined for association with ABPM session success rate. These patient characteristics included age, sex, weight, height, body mass index (BMI), occupation, clinic blood pressure, travel distance to clinic, and presence of diabetes mellitus or renal disease. The percentage of valid readings obtained during an ABPM session was analyzed continuously (0-100%), whereas overall session success was analyzed dichotomously (0-79% or 80-100%). Univariate and multivariate regression analyses were performed to examine the influence of patient characteristics on the percentage of valid readings and the overall likelihood of achieving a successful session. In the 530 patients, the average percentage of valid readings was 90%, and a successful ABPM session (>or= 80% valid readings) was obtained in 84.7% (449 patients). A diagnosis of diabetes was found to negatively predict ABPM session success (continuous variable analysis, p=0.019; dichotomous variable analysis, odds ratio [OR] 0.45, 95% confidence interval [CI] 0.23-0.87, p=0.019), as did renal disease (continuous variable analysis, p=0.006; dichotomous variable analysis, OR 0.39, 95% CI 0.17-0.90, p=0.027) and increasing BMI (continuous variable analysis, p<0.001; dichotomous variable analysis, OR 0.78, 95% CI 0.65-0.93, p=0.005). Renal disease and BMI remained significant predictors in adjusted analyses. CONCLUSION: For most patients, ABPM was successful; however, elevated BMI and renal disease were associated with less complete ABPM session results. Adaptation and individualization of the ABPM process may be necessary to improve results in these patients.
