    Input: The efficacy of self-recording of blood pressure in the management of hypertension was assessed in a r and omized clinical trial involving 140 persons who had been receiving antihypertensive therapy for a year or more , but whose diastolic blood pressure had remained at 95 mm Hg or higher . To control for the increased attention implicit in self-recording , which might affect blood pressure , the patients were assigned at r and om to one of the four groups : self-recording and monthly home visits , self-recording only , monthly home visits only , and neither self-recording nor monthly home visits . This design also permitted assessment of the effect of home visits . During the 6-month experiment no significant differences were apparent between the groups in either compliance or diastolic blood pressure . However , both self-recording and monthly home visits produced a reduction in blood pressure among patients who admitted to difficulty remembering to take their pills ; a reduction was not seen among patients who said they had no such difficulty . This confirmed an earlier observation suggesting that this easily identified group of patients may be the most responsive to intervention programs Background —Hypertension is a leading mortality risk factor yet inadequately controlled in most affected subjects . Effective programs to address this problem are lacking . We hypothesized that an information technology – supported management program could help improve blood pressure ( BP ) control . Methods and Results —This r and omized controlled trial included 223 primary care hypertensive subjects with mean 24-hour BP > 130/80 and daytime BP > 135/85 mm Hg measured with ambulatory monitoring ( ABPM ) . Intervention subjects received a BP monitor and access to an information technology – supported adherence and BP monitoring system providing nurses , pharmacists , and physicians with monthly reports . Control subjects received usual care . The mean ( ±SD ) follow-up was 348 ( ±78 ) and 349 ( ±84 ) days in the intervention and control group , respectively . The primary end point of the change in the mean 24-hour ambulatory BP was consistently greater in intervention subjects for both systolic ( −11.9 versus −7.1 mm Hg ; P<0.001 ) and diastolic BP ( −6.6 versus −4.5 mm Hg ; P=0.007 ) . The proportion of subjects that achieved Canadian Guideline target BP ( 46.0 % versus 28.6 % ) was also greater in the intervention group ( P=0.006 ) . We observed similar BP declines for ABPM and self-recorded home BP suggesting the latter could be an alternative for confirming BP control . The intervention was associated with more physician-driven antihypertensive dose adjustments or changes in agents ( P=0.03 ) , more antihypertensive classes at study end ( P=0.007 ) , and a trend toward improved adherence measured by prescription refills ( P=0.07 ) . Conclusions —This multidisciplinary information technology – supported program that provided feedback to patients and healthcare providers significantly improved blood pressure levels in a primary care setting OBJECTIVE : To evaluate the effectiveness of a community pharmacist-based home blood pressure ( BP ) monitoring program . DESIGN : Trial of a high-intensity ( HI ) versus low-intensity ( LI ) intervention r and omized in 12 community pharmacies . The HI intervention comprised 4 face-to-face visits with a trained pharmacist . Pharmacists provided patient-specific education about hypertension . Following the first and third visits , patients were provided with a home BP monitoring device and instructed to measure their BP at least once daily for the next month . Home BP readings were used by the pharmacists to develop treatment recommendations for the patient ’s physician . Recommendations were discussed with the physician and , if approved , implemented by the pharmacist . In the LI intervention , pharmacists measured patients BP in the pharmacy and referred them to their physician for evaluation . PARTICIPANTS : Patients with uncontrolled BP at baseline . MEASUREMENTS : The main outcomes were the differences in systolic and diastolic BP ( SBP and DBP ) from baseline to follow-up between the HI and LI patients . RESULTS : The study enrolled 125 patients , 64 in the HI and 61 in the LI group . From baseline , SBP declined 13.4 mmHg in the HI group and 9.0 mmHg in the LI group . At the final visit , the difference in SBP/DBP change between the HI and LI group was −4.5/−3.2 mmHg ( P=.12 for SBP and P=.03 for DBP ) . CONCLUSIONS : The HI intervention achieved a lower DBP and this model could be a strategy for patients with hypertension Home blood pressure monitoring ( HBPM ) overcomes many of the limitations of traditional office blood pressure ( BP ) measurement and is both cheaper and easier to perform than ambulatory BP monitoring . Monitors that use the oscillometric method are currently available that are accurate , reliable , easy to use , and relatively inexpensive . An increasing number of patients are using them regularly to check their BP at home , but although this has been endorsed by national and international guidelines , detailed recommendations for their use have been lacking . There is a rapidly growing literature showing that measurements taken by patients at home are often lower than readings taken in the office and closer to the average BP recorded by 24-hour ambulatory monitors , which is the BP that best predicts cardiovascular risk . Because of the larger numbers of readings that can be taken by HBPM than in the office and the elimination of the white-coat effect ( the increase of BP during an office visit ) , home readings are more reproducible than office readings and show better correlations with measures of target organ damage . In addition , prospect i ve studies that have used multiple home readings to express the true BP have found that home BP predicts risk better than office BP ( class IIa ; level of evidence A ) . This call-to-action article makes the following recommendations : 1 ) It is recommended that HBPM should become a routine component of BP measurement in the majority of patients with known or suspected hypertension ; 2 ) Patients should be advised to purchase oscillometric monitors that measure BP on the upper arm with an appropriate cuff size and that have been shown to be accurate according to st and ard international protocol s. They should be shown how to use them by their healthcare providers ; 3 ) Two to three readings should be taken while the subject is resting in the seated position , both in the morning and at night , over a period of 1 week . A total of > /=12 readings are recommended for making clinical decisions ; 4 ) HBPM is indicated in patients with newly diagnosed or suspected hypertension , in whom it may distinguish between white-coat and sustained hypertension . If the results are equivocal , ambulatory BP monitoring may help to establish the diagnosis ; 5 ) In patients with prehypertension , HBPM may be useful for detecting masked hypertension ; 6 ) HBPM is recommended for evaluating the response to any type of antihypertensive treatment and may improve adherence ; 7 ) The target HBPM goal for treatment is < 135/85 mm Hg or < 130/80 mm Hg in high-risk patients ; 8) HBPM is useful in the elderly , in whom both BP variability and the white-coat effect are increased ; 9 ) HBPM is of value in patients with diabetes , in whom tight BP control is of paramount importance ; 10 ) Other population s in whom HBPM may be beneficial include pregnant women , children , and patients with kidney disease ; and 11 ) HBPM has the potential to improve the quality of care while reducing costs and should be reimbursed It is still uncertain whether one can safely base treatment decisions on self-measurement of blood pressure . In the present study , we investigated whether antihypertensive treatment based on self-measurement of blood pressure leads to the use of less medication without the loss of blood pressure control . We r and omly assigned 430 hypertensive patients to receive treatment either on the basis of self-measured pressures ( n=216 ) or office pressures ( OPs ; n=214 ) . During 1-year follow-up , blood pressure was measured by office measurement ( 10 visits ) , ambulatory monitoring ( start and end ) , and self-measurement ( 8 times , self-pressure group only ) . In addition , drug use , associated costs , and degree of target organ damage ( echocardiography and microalbuminuria ) were assessed . The self-pressure group used less medication than the OP group ( 1.47 versus 2.48 drug steps ; P<0.001 ) with lower costs ( $ 3222 versus $ 4420 per 100 patients per month ; P<0.001 ) but without significant differences in systolic and diastolic OP values ( 1.6/1.0 mm Hg ; P=0.25/0.20 ) , in changes in left ventricular mass index ( -6.5 g/m(2 ) versus -5.6 g/m(2 ) ; P=0.72 ) , or in median urinary microalbumin concentration ( -1.7 versus -1.5 mg per 24 hours ; P=0.87 ) . Nevertheless , 24-hour ambulatory blood pressure values at the end of the trial were higher in the self-pressure than in the OP group : 125.9 versus 123.8 mm Hg ( P<0.05 ) for systolic and 77.2 versus 76.1 mm Hg ( P<0.05 ) for diastolic blood pressure . These data show that self-measurement leads to less medication use than office blood pressure measurement without leading to significant differences in OP values or target organ damage . Ambulatory values , however , remain slightly elevated for the self-pressure group BACKGROUND St and ard office-based approaches to controlling hypertension show limited success . Such suboptimal hypertension control reflects in part the absence of both an infrastructure for patient education and frequent , regular blood pressure ( BP ) monitoring . We tested the efficacy of a physician-directed , nurse-managed , home-based system for hypertension management with st and ardized algorithms to modulate drug therapy , based on patients ' reports of home BP . METHODS We r and omized out patients requiring drug therapy for hypertension according to the Joint National Committee on Prevention , Detection , Evaluation , and Treatment of High Blood Pressure ( JNC VI ) criteria to receive usual medical care only ( UC , n = 76 ) or usual care plus nurse care management intervention ( INT , n = 74 ) over a 6-month period . RESULTS Patients receiving INT achieved greater reductions in office BP values at 6 months than those receiving UC : 14.2 + /- 18.1 versus 5.7 + /- 18.7 mm Hg systolic ( P < .01 ) and 6.5 + /- 10.0 versus 3.4 + /- 7.9 mm Hg diastolic , respectively ( P < .05 ) . At 6 months , we observed one or more changes in drug therapy in 97 % of INT patients versus 43 % of UC patients , and 70 % of INT patients received two or more drugs versus 46 % of UC . Average daily adherence to medication , measured by electronic drug event monitors , was superior among INT subjects ( mean + /- SD , 80.5 % + /- 23.0 % ) than among UC subjects ( 69.2 + /- 31.1 % ; t(113 ) = 2.199 , P = .03 ) . There were no significant adverse drug reactions in either group . CONCLUSIONS Telephone-mediated nurse management can successfully address many of the systems-related and patient-related issues that limit pharmacotherapeutic effectiveness for hypertension BACKGROUND Telemedicine is a promising but largely unproven technology for providing case management services to patients with chronic conditions who experience barriers to access to care or a high burden of illness . METHODS The authors conducted a r and omized , controlled trial comparing telemedicine case management to usual care , with blinding of those obtaining outcome data , in 1,665 Medicare recipients with diabetes , aged 55 years or greater , and living in federally design ated medically underserved areas of New York State . The primary endpoints were HgbA1c , blood pressure , and low-density lipoprotein ( LDL ) cholesterol levels . RESULTS In the intervention group ( n = 844 ) , mean HgbA1c improved over one year from 7.35 % to 6.97 % and from 8.35 % to 7.42 % in the subgroup with baseline HgbA1c > or = 7 % ( n = 353 ) . In the usual care group ( n = 821 ) mean HgbA1c improved over one year from 7.42 % to 7.17 % . Adjusted net reductions ( one-year minus baseline mean values in each group , compared between groups ) favoring the intervention were as follows : HgbA1c , 0.18 % ( p = 0.006 ) , systolic and diastolic blood pressure , 3.4 ( p = 0.001 ) and 1.9 mm Hg ( p < 0.001 ) , and LDL cholesterol , 9.5 mg/dL ( p < 0.001 ) . In the subgroup with baseline HgbA1c > or = 7 % , net adjusted reduction in HgbA1c favoring the intervention group was 0.32 % ( p = 0.002 ) . Mean LDL cholesterol level in the intervention group at one year was 95.7 mg/dL. The intervention effects were similar in magnitude in the subgroups living in New York City and upstate New York . CONCLUSION Telemedicine case management improved glycemic control , blood pressure levels , and total and LDL cholesterol levels at one year of follow-up African Americans have a higher prevalence of hypertension and poorer cardi 
    Output:
    
For SMBP monitoring plus additional support versus SMBP monitoring alone or with less intense additional support ( 13 comparisons ) , low-strength evidence fails to support a difference .
Across all comparisons , evidence for clinical outcomes is insufficient .
For other surrogate or intermediate outcomes , low-strength evidence fails to show differences .
Self-measured BP monitoring with or without additional support lowers BP compared with usual care , but the BP effect beyond 12 months and long-term benefits remain uncertain .
Additional support enhances the BP-lowering effect .
