3 Adult Hypertension Clinical Practice Guidelines Purpose This guideline was developed by the KP National Hypertension Guideline Development Team (GDT) (Appendix A) to assist primary care physicians and other health care professionals in the outpatient treatment of hypertension in non-pregnant adults aged 18 and older. Background This guideline is an interim update of the 2016 KP National Clinical Practice Guideline for Hypertension. Recommendations are based on the 2014 Evidence-Based Guideline for the Management of High Blood Pressure in Adults Report from the Panel Members Appointed to the Eighth Joint National Committee (JNC 8) 1 and the 2015 United States Preventive Services Task Force (USPSTF) recommendations for Screening for High Blood Pressure. 2 Major changes in this interim update are: The addition of the USPSTF 2015 recommendations for screening and diagnosis of high blood pressure. Methods KP National Guideline Program follows a methodology 3 that incorporates well-established scientific frameworks to critically appraise evidence and evaluate external guidelines. In developing these recommendations, the GDT considered the 2014 KP recommendations and the 2015 USPSTF recommendations. The GDT s decisions and justification are outlined in Appendix B1. Recommendations are accompanied by language that clinicians should use to weigh the strength of the recommendation against the individual patient situation. The KP National Guideline methodology, updated most recently in 2016, streamlines ratings to strong, weak, or no recommendation (i.e., when evidence is reviewed but is inadequate to drive a recommendation for or against an intervention). The current KP guidelines evolved from multiple rating systems. Appendix B2 provides a crosswalk to compare language between current KP guidelines, JNC8, and the USPSTF. The GDTs develop guideline recommendations using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) criteria, which considers the balance between desirable and undesirable effects, quality of evidence, patient values and preferences, and resource use. When the GDT changes a previous KP guideline, adapts an external guideline with some modifications, or reviews new evidence to inform its recommendation, the GRADE framework provides transparency into those decisions. Appendix C summarizes GDT deliberations from the GRADE process. KP recommendations that were unchanged and external guidelines that were adopted verbatim are not subject to GRADE assessment. Additional evidence review work that was completed to inform the development of these recommendations can be found in Appendix D. This includes an assessment of the quality of the JNC8 recommendations and the 2015 USPSTF recommendations for KP adoption using the AGREE II 4 tool. 3

4 Recommendations Topic: Screening and Diagnosis of High Blood Pressure Screen all adults aged 18 for hypertension. (Strong Recommendation) o For adults aged years with normal blood pressure (< 130/85 mm Hg) without other risk factors, screen every 3 to 5 years. o For adults aged 40 years and those at increased risk of high blood pressure, screen annually. Persons at increased risk include those who have high-normal blood pressure ( / mm Hg), who are overweight or obese, and African Americans. Obtain measurements outside of the clinical setting for diagnostic confirmation before starting treatment. (Strong Recommendation) Topic: Treatment Initiation and Blood Pressure Targets In the general population aged 60 years, initiate pharmacologic treatment to lower blood pressure (BP) at systolic blood pressure (SBP) 150mm Hg or diastolic blood pressure (DBP) 90 mm Hg and treat to a goal SBP < 150 mm Hg and goal DBP < 90 mm Hg. (Strong Recommendation) In the general population aged 60 years, consider not adjusting treatment if pharmacologic treatment for high BP results in lower achieved SBP (e.g.,< 140mmHg) and treatment is well tolerated and without adverse effects on health or quality of life. (Weak Recommendation) In the general population < 60 years, initiate pharmacologic treatment to lower BP at DBP 90mmHg and treat to a goal DBP < 90mmHg. (Strong Recommendation) This is an adapted recommendation. In the general population < 60 years, initiate pharmacologic treatment to lower BP at SBP 140mmHg and treat to a goal SBP < 140mmHg. (Strong recommendation) This is an adapted recommendation. In the population aged 60 years with chronic kidney disease (CKD), consider initiating pharmacologic treatment at SBP 140mmHg or DBP 90 mmhg and treat to goal SBP < 140mmHg and goal DBP < 90mmHg. (Weak Recommendation)** This is an adapted recommendation. **When weighing the risks and benefits of a lower BP goal for people aged 70 years with estimated GFR < 60 ml/min/ 1.73m2, antihypertensive treatment should be individualized, taking into consideration factors such as frailty, comorbidities, albuminuria, and estimation of non-agerelated egfr decline (e.g.,, egfr + (age/2) < 85). In the population aged 60 years with diabetes, initiate pharmacologic treatment to lower BP at SBP 140mmHg or DBP 90mmHg and treat to a goal SBP < 140mmHg and goal DBP < 90mmHg. (Strong Recommendation) This is an adapted recommendation. 4

5 In the general non-african American population, including those with diabetes, consider initiating antihypertensive treatment to include a thiazide-type diuretic, calcium channel blocker (CCB), angiotensin-converting enzyme inhibitor (ACEI), or angiotensin receptor blocker (ARB). (Weak Recommendation) In the general African American population, including those with diabetes, consider initiating initial antihypertensive treatment to include a thiazide-type diuretic or CCB. (Weak Recommendation) In the population aged 18 years with CKD, consider initial (or add-on) antihypertensive treatment that includes an ACEI or ARB to improve kidney outcomes. This applies to all CKD patients with hypertension regardless of race or diabetes status. (Weak Recommendation) The main objective of hypertension treatment is to attain and maintain goal BP. If goal BP is not reached within a month of treatment, consider increasing the dose of the initial drug or add a second drug from one of the thiazide-type diuretic, CCB, ACEI, or ARB classes. The clinician should consider continued assessment of BP and adjust the treatment regimen until goal BP is reached. If goal BP cannot be reached with 2 drugs, consider adding and titrating a third drug from the indicated classes. Consider avoiding combined use of an ACEI and an ARB. If goal BP cannot be reached using only the drugs in these classes because of contraindications or the need for more than 3 drugs to reach goal BP, antihypertensive drugs from other classes can be considered. Consider referral to a hypertension specialist for patients in whom goal BP cannot be attained using the above strategy or for the management of complicated patients for whom additional clinical consultation is needed.

14 Appendix C: Rationale for KP-Modified Recommendation Topic: Diastolic Blood Pressure Targets Recommendation In the general population <60 years, initiate pharmacologic treatment to lower BP at DBP 90 mmhg and treat to a goal DBP < 90 mmhg. (Strong Recommendation) Basis of Recommendation There is strong evidence for this recommendation for ages 30 to 59. There is insufficient evidence to determine an optimal DBP goal in people ages 18 to 29. No high quality outcome trials assessing optimal diastolic blood pressure targets included large numbers of adults ages 18 to 29. The balance between benefit and harm from a DBP goal lower than < 90 mmhg for ages 18 to 29 cannot be determined; however, expert opinion favors the use of this goal, and risk of harm is expected to be low. Despite the low quality of evidence and the unknown balance of desirable and undesirable effects, a strong recommendation is warranted based on the discourse of the JNC 8 and its implications for health care delivery implementation. GRADE criteria Balance of desirable and undesirable effects Quality of Evidence Values and Preferences Resource Implications GRADE assessment Outcome evidence for patients aged 30 to 59 demonstrates that lower DBP is associated with lower rates of CVD. However, for patients 18 to 29 the optimal goal DBP has not been determined in wellconducted randomized controlled trials. The balance between risks of overtreatment of younger individuals versus the potential benefits of a lower DBP target is unknown but expected to be significant. Strong for ages 30 to 59. For ages 18 to 29: Expert opinion- while there is insufficient/unclear evidence we agree with the discourse of the JNC 8 committee and its recommendations. 1 This recommendation places a low value on preventing undertreatment of younger people and a higher value on the potential high expected reduction of CV events with DBP targets. Values and preferences were derived by polling the GDT. Uncertainty around and variability of values and preferences regarding hypertension therapy among patients are estimated to be high. Low to moderate because agents are of low-to-moderate cost and therapy of hypertension has been shown in some populations to becost effective with reduced morbidity and mortality. Uncertainty: Moderate because net benefits are unknown and outcome studies of comparative effectiveness are lacking. 14

15 Topic: Systolic Blood Pressure Targets Recommendation Basis of Recommendation GRADE criteria Balance of desirable and undesirable effects Quality of Evidence Values and Preferences Resource Implications In the general population < 60 years, initiate pharmacologic treatment to lower BP at SBP < 140mmHg and treat to a goal SBP < 140 mmhg. (Strong recommendation) There is insufficient evidence to determine an optimal SBP goal in people aged < 60 years. No high quality outcome trials assessing optimal systolic blood pressure targets included large numbers of adults younger than 60 years. The balance between benefit and harm from a BP goal < 140 mmhg cannot be determined; however, expert opinion favors the use of this goal and risk of harm is expected to be low. Despite the low quality of evidence and the unknown balance of desirable and undesirable effects, a strong recommendation is warranted based on the discourse of the JNC 8 and its implications for health care delivery implementation. GRADE assessment Pathophysiological evidence in younger people suggests that lower SBP is associated with lower rates of CVD. However, the optimal goal SBP has not been determined in well-conducted randomized controlled trials. The balance between risks of overtreatment of younger individuals versus the potential benefits of a lower SBP target is unknown but expected to be significant. Expert opinion-although there is insufficient/unclear evidence, we agree with the discourse of the JNC 8 and its recommendations. 1 This recommendation places a low value on preventing undertreatment of younger people and a higher value on the potential high expected reduction of CV events with SBP targets. Values and preferences were derived by polling the GDT. Uncertainty around and variability of values and preferences regarding hypertension therapy among patients are estimated to be high. Low to moderate because agents are of low-to- moderate cost and therapy of hypertension has been shown in some populations to be cost-effective with reduced morbidity and mortality. Uncertainty: Moderate because net benefits are unknown and outcome studies of comparative effectiveness are lacking. 15

16 Topic: Hypertension Treatment in Patients with CKD Recommendation In the population aged 60 years with chronic kidney disease (CKD), consider initiating pharmacologic treatment to lower BP at SBP 140 mmhg or DBP 90 mmhg and treat to goal SBP <140 mmhg and goal DBP <90 mmhg. (Weak Recommendation)** **When weighing the risks and benefits of a lower BP goal for people aged 70 years with estimated GFR < 60 ml/min/ 1.73m2, antihypertensive treatment should be individualized, taking into consideration factors such as frailty, comorbidities, albuminuria, and estimation of non-age-related egfr decline (for example egfr + 1/2 age < 85). Basis of Recommendation For individuals aged < 60 years, regardless of comorbidity of CKD, the prior strong recommendations apply. There is insufficient evidence to determine an optimal BP goal in people aged 70 years with CKD and on the diagnostic criteria for CKD that would identify people who would benefit from a BP goal lower than <150/90 mmhg. No outcome trials included large numbers of adults aged 70 years with CKD. The balance between benefit and harm from a BP goal lower than <150/90 mmhg cannot be determined; however, some expert opinions favor more aggressive treatment of people aged 70 years with CKD. Thus, when weighing the risks and benefits of a lower BP goal for people aged 70 years with estimated GFR < 60 ml/min/ 1.73m2, antihypertensive treatment should be individualized. Given the low quality of evidence and the unknown balance of desirable and undesirable effects, a weak recommendation is warranted. GRADE criteria Balance of desirable and undesirable effects GRADE assessment Pathophysiological evidence in younger people suggests that lower BP is associated with less progression of renal disease. However, the optimal goal BP goal has not been determined in high-quality randomized controlled trials. Those trials excluded people aged 70 years, so the effect of a more aggressive BP goal is unknown in elderly people with CKD. There is also no evidence on the definition of CKD that would identify elderly people who might benefit from BP goal lower than the strong recommendation of <150/90 mmhg for the general population aged 60 years. The commonly used estimating equations for GFR were not developed in populations with significant numbers of people aged 70 years and have not been validated in older adults. Observational data suggest that a modified definition of CKD (for example, egfr + (age/2) < 85) may indicate individuals more likely to progress to ESRD who may be candidates for a lower BP goal. The balance between risk of overtreatment of older individuals with CKD versus the potential benefits of a lower SBP target is unknown. Quality of Evidence Very low quality (indirect evidence) 1,5,6 Values and Preferences Resource Implications This recommendation places a high value on preventing overtreatment of elderly people and a lower value on the small risk of harms of increased CV and renal risk potentially associated with slightly higher SBP targets. Values and preferences were derived by polling the GDT. Uncertainty around and variability of values and preferences regarding hypertension therapy among patients in whom a treatment decision for lower SBP target is unclear are estimated to be high. Low to moderate because agents are of low-to-moderate cost and therapy of hypertension has been shown in some populations to be costeffective with reduced morbidity and mortality. Uncertainty: Moderate because net benefits are unknown and outcome studies of comparative effectiveness are lacking. 16

17 Topic: Blood Pressure Targets in the Diabetic Population 60 years Recommendation Basis of Recommendation GRADE criteria Balance of desirable and undesirable effects Quality of Evidence Values and Preferences Resource Implications In the population aged 60 years with diabetes, initiate pharmacologic treatment to lower BP at SBP 140mmHg or DBP 90 mmhg and treat to a goal SBP <140 mmhg and goal DBP <90 mmhg. (Strong Recommendation) For individuals aged 60 years, regardless of comorbidity of DM, the prior strong recommendations apply. There is insufficient evidence to determine an optimal BP goal in adults with DM aged > 60 years. No high-quality outcome trials comparing systolic blood pressure targets of 140 vs. 150 mm Hg included large numbers of adults with DM. The balance between benefit and harm from a SBP goal <140 mmhg cannot be determined; however, expert opinion favors the use of this goal and risk of harm is expected to be low. Despite the low quality of evidence, and the unknown balance of desirable and undesirable effects, a strong recommendation is warranted as based on the discourse summarized by the JNC 8 and its implications for health care delivery implementation. GRADE assessment Pathophysiological evidence suggests that lower BP is associated with lower rates of CVD. However, the optimal goal BP has not been determined in well-conducted randomized controlled trials including individuals with diabetes. The balance between risks of overtreatment versus the potential benefits of a lower BP target is unknown but expected to be significant. Expert opinion-although there is insufficient/unclear evidence, we agree with the discourse of the JNC 8 and its recommendations. 1 This recommendation places a low value on preventing undertreatment of adults with diabetes and a higher value on the potential high expected reduction of CV events with lower SBP targets. Values and preferences were derived by polling the GDT. Uncertainty around and variability of values and preferences regarding hypertension therapy among patients are estimated to be high. Low to moderate because agents are of low-to-moderate cost and therapy of hypertension has been shown in some populations to be cost-effective with reduced morbidity and mortality. Uncertainty: Moderate because net benefits are unknown and outcome studies of comparative effectiveness are lacking. 17

18 Appendix D: Systematic Review Topic: Screening and Diagnosis of High Blood Pressure The NGP methodology calls for the KP guideline development process to first seek high-quality external guidelines for adoption or adaption and to conduct additional evidence review only as needed. 3 The Hypertension National Guideline Lead Team conducted a review of existing KP regional guidelines and potential high-quality existing guidelines on hypertension available for adaption or adoption. The Lead Team determined that the USPSTF recommendations for screening and diagnosis for high blood pressure best addressed the needs of the NGP and proceeded to analyze the quality and content of this guideline for comprehensiveness and adoption to the KP NGP. The final product of this KP recommendation is based on the USPSTF recommendation. Screening frequency is addressed as a clinical consideration by USPSTF and is therefore presented similarly in the KP clinician guide. AGREE II Summary The AGREE (Appraisal of Guidelines Research and Evaluation) 4 II tool is used to assess the methodological quality of existing clinical practice guidelines being considered for adoption into the NGP portfolio. An AGREE assessment was completed on the USPSTF recommendations in 2016 (using the completed 2014 evidence review) 7 and it was considered to be of good quality and rigor; no additional evidence review was conducted by KP. To access the link to the completed AGREE II assessment click below: 2016 USPSTF Blood Pressure Screening and Diagnosis AGREE II Assessment Following are the key questions addressed by the USPSTF recommendations: Key Questions 1. Does screening for high blood pressure reduce cardiovascular disease and mortality in adults aged 18 years or older? 2. What is the best way to screen for high blood pressure in adults in the primary care setting? a. How accurate (i.e., sensitivity, specificity, and predictive value) are clinic-based blood pressure measurement methods (e.g., manual vs. automated) in provisionally diagnosing hypertension within a single visit? b. What screening protocol characteristics within a single encounter (e.g., sitting quietly for 5 minutes or number of readings) define the best diagnostic accuracy? 3. What is the best way to confirm hypertension in adults who initially screen positive for high blood pressure? a. How well do home and ambulatory blood pressure monitoring methods predict cardiovascular events compared with clinic-based blood pressure measurement methods? What confirmation protocol characteristics define the best prediction of cardiovascular events? Which methods and associated protocols best predict cardiovascular events? b. How accurate are other noninvasive blood pressure measurement methods in establishing or confirming the diagnosis of hypertension, compared with these best methods and associated protocols? Does diagnostic accuracy vary by protocol characteristics (i.e., characteristics not reviewed in key question 2b, such as the number of visits)? c. Does changing the measurement method from that used during the initial screening improve diagnostic accuracy for some specific patient subgroups (e.g., those with suspected white-coat hypertension)? 4. What is the clinically appropriate rescreening interval for patients who have previously been screened and found to have normal blood pressure? a. What is the shortest interval in which clinically significant, diagnosed hypertension may develop? b. Does the rescreening interval vary by patient characteristics (e.g., age, sex, race/ethnicity, cardiovascular risk, blood pressure, or screening history)? 5. What are the adverse effects of screening for high blood pressure in adults? Inclusion/Exclusion Criteria USPSTF conducted a comprehensive literature search for existing systematic reviews from various databases including MEDLINE and PubMed from January 1, 2005 to March 19, Various databases including MEDLINE and PubMed were searched for randomized controlled trials (Questions 1 and 5), cohort studies (Questions 4 and 5), and diagnostic accuracy studies (Question 2 and 3) published between 1966 and February 24, A full list of databases searched for each question can be found in the published evidence review. 7 Reference lists of included studies were also reviewed. A total of 19,309 titles and abstracts and 1,171 full-text articles were reviewed. In general, studies were included if they were conducted in adult populations (i.e., > 80% of the study population was aged 18 years) in primary care settings. If conducted in adults and children, results had to be stratified by age group. Participants must not have been taking antihypertensive medications (except for Question 3a). Studies with pregnant women, institutionalized persons, inpatients, and persons with an underlying cause 18

19 of high BP were excluded. In addition, studies that enrolled a highly selected group of participants (e.g. renal transplant recipients or those with chronic kidney disease) were excluded. Blood pressure measurements had to be taken on the upper arm. Studies with measurements using the wrist, ankle, finger, and toe blood pressure monitors were excluded. Studies using blood pressure measurement methods not commonly used in routine screening practices (e.g. invasive methods or noninvasive central blood pressure measurements) were excluded. Details regarding inclusion/exclusion criteria can be found in the published evidence review. 7 USPSTF Analytic Framework Legend: ABPM = ambulatory blood pressure monitoring; BP = blood pressure; CHD = coronary heart disease; CVD = cardiovascular disease; ESKD = end-stage kidney disease; HBPM = home blood pressure monitoring; HF = heart failure. * Defined as the threshold for pharmacologic treatment. Topic: Treatment Initiation and Blood Pressure Targets The NGP methodology calls for the KP guideline development process to first seek high-quality external guidelines for adoption or adaption, and to conduct additional evidence review only as needed. 3 The Hypertension National Guideline Lead Team conducted a review of existing KP regional guidelines and potential high-quality existing guidelines on hypertension available for adaptation or adoption. The Lead Team determined that the JNC 8 1 guideline best addressed the needs of the NGP and proceeded to analyze the quality and content of this guideline for comprehensiveness and adoption to the KP NGP. The final product of the KP guideline is based primarily on the JNC 8 guideline. AGREE II Summary The AGREE (Appraisal of Guidelines Research and Evaluation) 4 II tool is used to assess the methodological quality of existing clinical practice guidelines being considered for adoption into the NGP portfolio. An AGREE assessment was completed on the JNC 8 guideline in 2014 and it was considered to be of good quality and rigor; no additional evidence review was conducted by KP. Following are the key questions addressed by the JNC 8 guideline: Key Questions 1. In adults with hypertension, does initiating antihypertensive pharmacologic therapy at specific blood pressure thresholds improve health outcomes? 2. In adults with hypertension, does treatment with antihypertensive pharmacologic therapy to a specified BP goal lead to improvements in health outcomes? 3. In adults with hypertension, do various antihypertensive drugs or drug classes differ in comparative benefits and harms on specific health outcomes? Inclusion/Exclusion Criteria The JNC 8 1 conducted an evidence review that focused on adults aged 18 years with hypertension and included studies with the following pre-specified subgroups: diabetes, coronary artery disease, peripheral artery disease, heart failure, previous stroke, chronic kidney disease (CKD), proteinuria, older adults, men and women, racial and ethnic groups, and smokers. Studies with sample sizes < 100 were excluded, as were studies with a follow-up period of less than a year, because small studies of brief duration are unlikely to yield enough health-related outcome information to permit interpretation of treatment effects. 19

20 Studies were included in the evidence review only if they reported the effects of the studied interventions on any of these important health outcomes: Overall mortality, cardiovascular disease (CVD)-related mortality, CKD-related mortality Myocardial infarction, heart failure, hospitalization for heart failure, stroke Coronary revascularization (includes coronary artery bypass surgery, coronary angioplasty, and coronary stent placement), other revascularization (includes carotid, renal, and lower extremity revascularization) End-stage renal disease (ESRD) (i.e., kidney failure resulting in dialysis or transplantation), doubling of creatinine level, halving of glomerular filtration rate (GFR). 20
