ABSTRACT
BACKGROUND: Although some studies have demonstrated that pharmacist intervention can improve drug therapy among patients with cardiovascular disease (CVD), more evidence derived from randomized controlled trials (RCTs) is needed, including assessment of the effect of community phar-macist interventions in patients with CVD.
OBJECTIVE: To assess the effectiveness of the Dader Method for pharma-ceutical care on achieving therapeutic goals for blood pressure (BP), total cholesterol (TC), and both BP and TC (BP/TC) in patients with CVD and/or high or intermediate cardiovascular (CV) risk attending community pharma-cies in Spain.
METHODS: Patients aged 25 to 74 years attending community pharma-cies with a prescription for at least 1 drug indicated for CVD or CV risk factors were randomized to 2 groups: an intervention group that received pharmaceutical care, which was provided by specially trained pharmacists working in collaboration with physicians, and a control group that received usual care (routine dispensing counseling) and verbal and written coun-seling regarding CVD prevention. Patients were recruited from December 2005 to September 2006, and both groups were followed for 8 months. Study outcomes were assessed at baseline and at 16 and 32 weeks after randomization. The primary outcome measures were the proportions of patients achieving BP, TC, and BP/TC therapeutic goals (BP lower than 140/90 mm Hg for patients with uncomplicated hypertension and lower than 130/80 mm Hg for patients with diabetes, chronic kidney disease, or history of myocardial infarction or stroke; TC lower than 200 mg per dL for patients without CVD and lower than 175 mg per dL for patients with CVD). Secondary outcomes were mean BP and TC values. BP was assessed manually by the pharmacist after a 10-minute rest in the supine position. This measurement was performed twice for every participant, and the average of the 2 measurements was calculated. TC was measured by the pharmacist during the study visit using the enzymatic dry method. Statistical analyses were performed using 2-tailed McNemar tests, Pearson chi-square tests, and Student’s t-tests; P < 0.05 was considered statisti-cally significant.
RESULTS: 714 patients were included in the study (356 intervention, 358 control), and the mean [SD] age was 62.8 [8.1] years. The 2 groups were similar at baseline in clinical and demographic characteristics, including the proportion of patients at therapeutic goals for BP, TC, and BP/TC. After 8 months of follow-up, there were statistically significant differences in favor of pharmaceutical care in the proportions of patients who achieved therapeutic goals for BP (52.5% vs. 43.0%, P = 0.017), TC (56.5% vs. 44.1%, P = 0.001), and BP/TC (37.1% vs. 21.8%, P <0.001).
RESEARCH
CONCLUSION: Compared with usual care plus written education, pharma-ceutical care focused on patient evaluation and follow-up in collaboration with physicians improved the achievement of BP, TC, and BP/TC treatment goals in patients with CVD and/or high or intermediate CV risk attending community pharmacies in Spain.

Communitypharmacists,incooperationwithpatientsandotherclinicians,couldmonitortherapeuticplansandcontrib-ute to the achievement of clinical outcomes in patientswithchronicdiseases.12Somestudieshaveshownthatpharmacistparticipation in designing, implementing, and monitoringtherapeuticprogramsinpatientswithCVDorCVriskfactorscould(a)improvethepatient’sknowledge,13(b)facilitateadop-tionofandoutcomesfromlifestyleinterventions,14(c)improvethe identification of candidates and the results of primary15 or secondary16prevention, and (d) increase thepercentageofpatients with high CV riskwho achieve the goals related toBP17-20 and lipid9,21 levels. Incontrast,other randomizedcon-trolled trials (RCTs) have found that community pharmacistinterventiondidnotleadtoimprovementsinprimaryoutcomemeasures (e.g., hospital admissions22 or the proportion ofpatientsreceivingappropriatemedication23).
Inasystematicreviewandassessmentofthequalityofstud-iesevaluatingcommunitypharmacistinterventionsinprevent-ingormanagingdiabetesorCVDand/ormajorCVriskfactors,Evansetal.(2011)foundthatstudyqualitywasgenerallypoor(poor design and/or poor reporting), most studies assessedonly biomarkers, and none of the studies demonstrated anybenefits in major health outcomes (e.g., hospital admissionsor mortality). They concluded that there is a need for morehigh-quality studies of community pharmacist interventionsinpatientswithCVD.24
Theobjectiveof thepresent studywas toassess theeffec-tivenessof theDaderMethod forpharmaceuticalcareon theachievementoftherapeuticgoalsforBP,totalcholesterol(TC),andbothBPandTC(BP/TC)inpatientswithCVDand/orhighor intermediateCV risk attending communitypharmacies inSpain.

What this study adds
Cardiovascular disease (CVD) is the leading cause ofmortalityanddisabilityworldwide.1Itisconsideredanimportant public health problem because of its high
prevalence,mortality,andnegativeeffectsonhealthandqual-ity of life.2 Therefore, prevention and treatment of CVD areessential elementsof chronicdisease control.3Despite recentadvances, evidence of benefits obtained with treatment andpreventionofCVD,andtheavailabilityoftreatmentguidelinessupported by the results of clinical studies,4 there is a gapbetween evidence-based recommendations and routine clini-calpractice.5Asaconsequence,manypatientsdonotreceivenecessary therapeutic interventions or do not achieve theirtherapeutic goals.6 For instance, in studies by Banegas et al.(1998)andRodríguez-Rocaetal.(2005),only15.5%-33.5%ofpatientsreceivingdrugtherapyforhypertensionachievedtheirblood pressure (BP) treatment goals,7,8 rates similar to thoseof patients with hypercholesterolemia.6,9 Olson et al.

Theprogram generated a sequence of 1,000 random numberswithnorepetition(1to1,000)andassignedthecodeONEto500 numbers and the code ZERO to the other 500. Finally,it grouped theprevious1,000 randomnumbers (codedONEorZERO) into50groupsof20.Eachpharmacy entered intothestudywhenthepharmacistsubmittedbyfaxoremailtherecordof the firstpatientwho fulfilled the inclusioncriteria.Once the study’s coordinator verified the fulfillment of theinclusion criteria, he randomly assigned 1 of thementioned50 groups to the pharmacy, providing it with a sequence of20codes(ONEorZERO)thatdeterminedwhichpatientwasassignedtotheinterventiongrouporthecontrolgroup.
Intervention Group: The Dader Method for Pharmaceutical CareThe Dader Method for pharmaceutical care is a systematicprocess developed by the ResearchGroup of PharmaceuticalCare at theUniversity of Granada, Spain.27 The interventionis based on the use of pharmacotherapy records, evaluationof an assessment form that includes all CV health problemsand theCVdrugsused to treat thesemedicalproblems, andtheirassessmentonaspecificdate.Thisassessmentisusedtoidentify(a)anypotentialoractualpatienthealthoutcomesthatarenotconsistentwiththeobjectivesofpharmacotherapyandare associatedwith the use ofmedicines (negative outcomesassociatedwithmedication[NOM])and(b)situationsinwhichtheuseofmedicinescausedormaycausetheappearanceofanNOM(drug-relatedproblems[DRP]).28Oncetherelevantprob-lemsareidentified,thenecessaryinterventionstopatientsortophysiciansarecarriedouttosolvetheidentifiedNOMandarefollowedbyasubsequentassessmentoftheachievedoutcomes.

Although these differ-encesmaybeattributedtothetype of practitioners(communitypharmacistsvs.hospitalclinicalpharmacists)andsetting(com-munitypharmacy vs. secondary care outpatient clinic in theuniversity hospital), amore likely explanation is that, in thestudybyMorgadoetal.,onlypatientsintheinterventiongroupwereprovidedwithwritteneducationalmaterialabouthyper-tensionandpossiblecomplications,aswellasinformationonhealthylifestylepractices.17Bycontrast,intheEMDADER-CVstudy,boththecontrolandtheinterventiongroupswerepro-videdwithwritteneducationalmaterialaboutCVriskfactorsandCVD andwere focused on goals and the importance ofadherence topharmacologicandnonpharmacologic interven-tionstoachievetherapeuticgoals.30WeconsiderthattobethereasonwhytheEMDADER-CVcontrolgroupshowedstatisti-cally significant increases in the percentage of patients whoachieved therapeutic goals forBP anddecreases in themeanvaluesofSBPandDBP.
In a 12-month, prospective, single-blind RCT by Hunt etal.(2008),designedtoevaluatetheeffectivenessofcollabora-tivemanagementofhypertensionbyprimarycare-pharmacistteamsincommunity-basedclinics,patientswithuncontrolledhypertension were randomized to a physician-pharmacistcollaborativemodel of care intervention (n=230) or tousualprimary care (n=233).18 According to an intention-to-treatanalysis in which chart review was used to obtain the lastrecordedbloodpressure values if thepatientmissed the lastclinic visit, this study reported that 54% (125/230) of thepatients in the intervention group achieved BP goals, com-paredwith42%(97/233)of thepatients in thecontrolgroup(P =0.005).Patients in the interventiongroupalsohad lowerSBP (–6mmHg, P =0.002) andDBP (–3mmHg, P =0.003)comparedwiththecontrolgroup(142/77mmHgvs.148/80mmHg).ThepercentageofpatientswhoachievedthetargetedBP in the study byHunt et al.was close to the value in theEMDADER-CV study; however, in the latter study, the inter-ventionandthecontrolgroupswerenotsignificantlydifferentintermsofDBP.Theinterventioninthephysician-pharmacistcollaborative model of care was similar to the interventionin the EMDADER-CV (the pharmacists reviewed subjects’

■■ DiscussionThe EMDADER-CV studywas a large (n=714 patients) RCTdesignedtoassesstheeffectoftheDaderMethodforpharma-ceuticalcareonachievingtherapeuticgoalsforBP,TC,andBP/TC in community pharmacy patientswithCVD and/or highor intermediateCV risk.Comparedwith usual care (routinedispensingandoralcounseling)pluswritteneducationalmate-rialaboutCVriskfactorsandCVD,pharmaceuticalcarepro-ducedsignificant improvements in thepercentageofpatientswho achieved therapeutic goals for BP, TC, and BP/TC. It isimportant to point out that the Dader Method incorporatedacombinationofstrategiesthatareconsideredkeytoachiev-ingbettercontrolofCVrisk,suchaspatienteducationonCVdrugs, completionof adrug therapyprofile and/ordrughis-tory,assessmentofdrugcompliance,patientcounselingaboutlifestylemodification,pharmacist-performedinterventionsnotrelated tochanges indrug therapy,andpharmacist-deliveredtreatmentrecommendationstophysicians.27,31
Toourknowledge, there isa lackof largerandomizedtri-als designed to evaluate the effect of community pharmacistinterventions in the achievement of therapeutic goals for BP,TC,andBP/TCinpatientswithCVDorCVriskfactors,whichwasthemainobjectiveoftheEMDADER-CVstudy.However,some studies, including some systematic reviews and meta-analysis,31-35 have demonstrated that pharmacist interventioncould improve theoutcomesofdrug therapy amongpatientswithhypertension17,18,21anddyslipidemia.9

In a recent systematic review and meta-analysis of 30RCTs (11,765 patients) by Santschi et al. (2011), conductedto determine the impact of pharmacist care on themanage-ment of CV risk factors among outpatients, pharmacist carewas associatedwith significant reductions inmean values ofSBPandDBP(–8.1mmHg,95%CI=–10.2 to–5.9and–3.8mmHg, 95%CI=–5.3 to –2.3, respectively).34 These resultsareconsiderablyhigher than thereductionsobtained inbothSBPandDBPintheEMADER-CVstudyandinthesystematicreviews conducted byMachado et al.32 andMorgado et al.33
DifferencesobtainedinthesystematicreviewsbyMachadoetal.,32Morgadoetal.,33andSantschietal.34mightbeshowingatendencytoanoverall incrementintreatmentadherenceinthemostrecentstudies,whichhavetendedtofavorpharmacistcare comparedwith usual care and includedmore interven-tions involving physician-pharmacist collaboration33 and asubstantial heterogeneity.34 Despite these quantitative differ-ences, all these studies, includingEMDADER-CV, found thatcommunitypharmacy interventions improve theoutcomesofdrugtherapyamongpatientswithhypertension.17,18,31-34
In the Study of Cardiovascular Risk Intervention byPharmacists (SCRIP), an RCT of a community pharmacistintervention in primary care of patients with dyslipidemia,Tsuyukietal.(2002)assigned675patientswithCVDordia-beteswithotherCVriskfactors toapharmacist interventionincluding education and a brochure about CV risk factors;point-of-carecholesterolmeasurement;referraltotheirphysi-cians;regularfollow-upfor16weeks;andriskfactorinforma-tionprovidedbythepharmacisttothephysician,ortousualcare including the brochure, general advice, and minimalfollow-up.9 The primary endpoint (performance of a fastingcholesterol panel by the physician or addition or increase indose of cholesterol-loweringmedication)was reached in 196patients(57%) inthe interventiongroup,comparedwith102(31%)intheusualcaregroup.Althoughtheprimaryendpointin theSCRIPwasdifferent than thegoals established forTCintheEMDADER-CVstudy,thepercentageofpatientsintheinterventiongroupwhoreachedtheprimaryendpointintheSCRIPwassimilar to thepercentageofpatientswhoreachedtherapeuticgoalsforTCinourstudy.9
The reduction in TC obtained in the intervention groupof the EMDADER-CV study is considerably lower than the
medicationsandlifestylehabits,assessedvitalsigns,screenedfor adverse drug reactions, identified barriers to treatmentadherence, provided education, and scheduled follow-up appointments as deemed necessary).

AsystematicreviewbyCarteretal.(2009),includingquasi-randomizedtrials,controlledbefore-afterstudies, interruptedtime-series studies, patient-randomized trials, and cluster-randomized trials anddesigned to assess the effectiveness ofinterventionsforBPinvolvingnursesorpharmacists,showedthatpharmacists’interventionswereassociatedwithasignifi-cantreductioninthemeanvalueofSBPwhenthepharmacistmadetreatmentrecommendationstothephysician(−9.30mmHg)orwhenthepharmacistperformedtheintervention(−8.44mmHg).31 In a nonparametric analysis of 13 studies involv-ingcommunitypharmacists,themean[SD]reductionsinSBPandDBPwere–9.31[5.00]and–4.59[4.64]mmHg.31Thesevaluesareclose to theresultsof theEMDADER-CVstudy, inwhich the intervention group experiencedmean [SD] reduc-tions inSBPandDBPof–11.3 [14.8]and–4.3 [9.8]mmHg,respectively. Additionally, based on the results of 5 studiesconducted in communitypharmacies,Carter et al. estimatedanORforcontrolledBPof2.89(95%CI=1.83-4.55)forcom-munitypharmacists,avaluehigherthantheORforcontrolledBPinourstudy(1.47,95%CI=1.08-1.99).However,Carteretal. clarified that if 2 studieswere excluded (1 because of anextremelyhighOR=29.7andtheotherbecausethepharmacistworkedcloselywith2physiciansandreviewedmedicalrecordsofstudyparticipantsinthephysicians’office,OR=4.29),and1additionalstudywasincluded(classifiedasanursinginterven-tionfortheORcalculations,buttheinterventioninvolvedbothanurseandacommunitypharmacist,OR=1.79),theestimatedORforcontrolledBPwouldhavebeen1.8,31avaluethatwouldbeclosertotheORobtainedintheEMDADER-CVstudy(1.47).
In the EMDADER-CV study, the difference in mean SBPin favorof the interventiongroupcomparedwith thecontrolgroupwas lower than that of –6.9 [12.0]mmHg (P =0.047)foundinthesystematicreviewbyMachadoetal.(2007)32butwasclosetothevalueof–4.9[0.9]mmHg(P <0.001)obtainedinthesystematicreviewbyMorgadoetal.(2011).33Bycontrast,neither theEMDADER-CVstudynor the reviewbyMachadoetal.32 foundsignificantdifferencesbetween the interventiongroup and the control group in DBP, whereas the differenceof –2.6 [0.9]mmHg (P <0.001)was significant in themeta-analysisbyMorgadoetal.33Inthemeta-analysesbyMachadoetal.32andbyMorgadoetal.,33thecontrolgrouppatientsdid

Finally, the EMDADER-CV studywas performed by care-fullyselectedcommunitypharmacists,whowere trainedandspecialized in pharmacotherapy follow-up and in using theDaderMethod,which limits thedegree towhich thepresentstudyfindingscanbegeneralizedtoothersettings.
■■ Conclusions Compared with usual care plus written education, pharma-ceutical care focused on patient evaluation and follow-up incollaboration with physicians improved the achievement ofBP,TC,andBP/TCtreatmentgoalsinpatientswithCVDand/or high or intermediate CV risk in a community pharmacysetting in Spain. The EMDADER-CV study demonstrates theaddedvalueofpharmaceuticalcarebycommunitypharmacistsinoutpatientswithCVDand/orhighorintermediateCVrisk.

LimitationsFirst, theresultsmighthavebeensubjectedtopotentialbias.Because therewasno “placebo” treatment, the studypatientswere not blinded to treatment assignment, and both groups(interventionandcontrol)wereseenbythesamecommunitypharmacist, who was responsible for collecting BP and TCmeasurements.However,potentialbiaswasreducedbyphar-macistuseofastandardizedprocessforcollectingBPandTCmeasurementsinboththeinterventionandcontrolgroups.
Second, control group patients received telephone callsfromthepharmacist,whoencouragedtheirattendanceattheappointments.Controlgrouppatientswerealsoprovidedwithwritten and oral education about CV risk factors and CVDandwerecounseledongoalsandtheimportanceofadherenceto pharmacological and nonpharmacological interventions toachievetherapeuticgoals,asrequestedbytheHumanResearchEthicalCommitteeinitsapprovalofthisresearchproject.Thecommittee also requested that pharmacists provide patientswith the results of BP and TC assessments. In addition, allpatients were questioned about knowledge of CVD, and 41werequestionedabouttreatmentadherence.Therefore,controlgroup patients received some intervention, and 10 patientsallocatedtotheecontrolwereexcludedfromthestudybecausepharmacistsdeterminedthatthepatientsneededintervention.Theeffectofwritteneducationalmaterialandtheextraatten-tionreceivedbythepatientsintheusualcaregroupmighthaveproducedpositiveoutcomesandreducedthemagnitudeofdif-ferencescomparedwiththeinterventiongroup.
