Effects of Nurse Management on the Quality of Heart Failure Care in Minority Communities
Context People with chronic conditions may need tailored , practical help for managing their conditions . Contribution This 12-month trial of assistance with managing systolic- dysfunction heart failure r and omly assigned 406 ethnically diverse adults from Harlem , New York , to usual care or nurse management .  Nurses counseled nurse management patients about sodium intake , fluid buildup , medication adherence , and self-management of symptoms ; served as a bridge between patients and physicians ; and regularly called patients to discuss problems . Compared with usual care patients , nurse management patients had fewer hospitalizations and better functioning . Implication s Nurse management can improve some outcomes in ethnically diverse patients with systolic-dysfunction heart failure in ambulatory practice s. The Editors Heart failure disproportionately affects black and elderly people and is a leading cause of hospitalization among people 65 years of age or older ( 1 , 2 ) . Although effective therapies can improve functioning and survival in patients with systolic dysfunction , many patients may not be receiving the full benefit of existing knowledge ( 35 ) . Patients play a critical role in managing a chronic condition , such as heart failure . Patients may not realize that specific symptoms are related to heart failure or that adhering to medications and diet can reduce symptoms and life-threatening episodes ( 6 ) . Evidence -based guidelines for systolic dysfunction recommend that physicians not only offer patients effective therapies but also teach them the importance of adherence and self-monitoring ( 3 , 4 ) . Clinicians have fallen short in prescribing angiotensin-converting enzyme inhibitors and -blockers for patients with systolic dysfunction ( 5 , 7 , 8) . When prescribed , the doses have often been lower than those proven to convey greater benefits ( 3 , 9 ) . Clinicians have also documented counseling only a fraction of patients with heart failure about self-management ( 10 , 11 ) . System-related factors may also influence patients ' ability to obtain quality care ( 12 , 13 ) . Systematic review s of clinical behavior change have suggested that interventions targeted to specific problems are more likely to be successful ( 14 , 15 ) . On the basis of shortfalls identified in patient self-management and clinical care in Harlem , New York , a predominately nonwhite area , we tailored a nurse management intervention to address documented problems and evaluated its effectiveness in a r and omized , controlled trial . Our trial among primarily minority patients addresses important gaps in the literature . We targeted problems documented among patients with heart failure in Harlem , enrolled patients from ambulatory care practice s , r and omly assigned patients to either nurse management or usual care , and evaluated the patients ' subsequent health-related outcomes . We hypothesized that patients in the  focused nurse management program  would have fewer hospitalizations and report better functioning than patients in usual care . Methods Development of the Intervention During interviews with patients with heart failure at Mount Sinai Hospital , New York , New York , patients reported inadequate underst and ing of heart failure and their role in managing it ( 6 ) . Less than half of patients followed a very-low-salt diet , and only about one quarter weighed themselves daily . Regarding clinical management , medical records noted prescriptions for an angiotensin-converting enzyme inhibitor or hydralazinedinitrate combination in 82 % of 322 consecutive black patients with documented systolic dysfunction who were scheduled for visits at the general medicine clinic at Harlem Hospital from February 1995 through February 1997 . The prescribed doses , however , equaled or exceeded those found to be efficacious in clinical trials in only 26 % of these patients ( 3 ) . In design ing a nurse management intervention to address these problems , we built on a Stanford University program that evaluated primarily privately insured patients at Kaiser Permanente in northern California ( 16 , 17 ) . We adapted their question naire on the frequency of foods eaten to incorporate those that are common among African-American and Hispanic people in Harlem . Setting s and Recruitment All 4 hospitals in Harlem , the area 's major providers , collaborated in the trial : 1 large private academic medical center ( 1171 beds ) , 2 medium-sized municipal hospitals ( 286 beds and 363 beds ) , and 1 smaller private community hospital ( 200 beds ) . In 2000 , these hospitals had 521 , 267 , 218 , and 168 discharges for the heart failure diagnosis-related group ( code 127 ) , respectively . All are not-for-profit institutions . The trial had the following inclusion criteria : adults 18 years of age or older ; systolic dysfunction documented on a cardiac test ( echocardiography , radionuclide ventriculography , myocardial stress sestamibi or thallium stress testing , or left-heart catheterization ) ; English- language or Spanish- language speakers ; community-dwelling at enrollment ; and current patient in a general medicine , geriatrics , or cardiology clinic or office at a participating site . Exclusion criteria were medical conditions that prevented interaction with the nurse , including blindness , deafness , or cognitive impairment ; medical conditions requiring individualized management that might differ from st and ard protocol , namely pregnancy , renal dialysis , or terminal illness ; or procedures that corrected systolic dysfunction , such as heart transplantation . Of the 216 clinicians ( 209 physicians and 7 physicians ' assistants or nurse practitioners ) in participating practice s , 1 clinician declined permission to recruit his patients . The institutional review boards for each site approved the study . We identified patients with International Classification of Diseases , Ninth Revision , Clinical Modification ( ICD-9-CM ) , and diagnosis-related group codes on outpatient or inpatient billings for heart failure , March 1999 through February 2001 , who had at least 1 clinician visit to a participating practice and impaired systolic dysfunction . We defined impaired systolic dysfunction as a left ventricular ejection fraction less than 0.40 or moderately or severely reduced systolic dysfunction on echocardiography , radionuclide ventriculography , myocardial stress sestamibi or thallium stress testing , or left-heart catheterization . We obtained clinicians ' permission to recruit specific patients and sent each approved patient a letter from the site 's physician coordinator . Bilingual recruiters telephoned eligible patients or approached them at scheduled clinician appointments . The recruiter confirmed each patient 's eligibility , obtained written informed consent to participate in the study , conducted the baseline survey , and telephoned the project manager for the treatment group assignment . The recruiter conveyed the assignment to the patient and , for each nurse management patient , scheduled the in-person appointment with a nurse . We provided telephone service for 3 patients who did not have it so we could telephone patients in both treatment groups every 3 months for data on end points and so nurse management patients could participate in the intervention . R and omization and Treatment Groups The project 's statistician used a computer-generated , r and om-number sequence without blocking or stratification to central ly determine r and omization assignments and concealed treatment group assignments in sealed , opaque envelopes . Usual care patients received federal consumer guidelines for managing systolic dysfunction but no other intervention ( 18 ) . In the nurse management intervention , 1 of 3 trained registered nurses met once with each patient ( Table 1 ) . In counseling the patient , the nurse stressed the relationship among sodium intake ; fluid buildup ; and symptoms , such as shortness of breath . Nurses mailed patients the reports from the food-frequency question naire after each administration . The nurse also served as a bridge between the patient and the clinician ( Table 1 ) . A local clinical advisory committee implemented national evidence -based guidelines , and a committee of key clinicians from participating sites approved the protocol ( 3 , 4 ) . Nurses contacted patients ' clinicians to discuss specific medications and arranged any prescription changes and examinations ordered ( Table 1 ) . An internist monitored the nurses ' work , initially in weekly and then in biweekly meetings , and a cardiologist provided oversight and substituted for the internist at regular meetings , as necessary . Table 1 . Components of Nurse Management * One nurse who was bilingual in English and Spanish delivered the intervention primarily at the 2 municipal hospitals , a second bilingual nurse delivered the intervention primarily at the small community hospital , and the second and a third English- language speaking nurse delivered the intervention primarily at the academic center . All 3 nurses covered each other , especially for the follow-up telephone calls . Outcomes and Measurement To measure hospitalizations , we used billing data from the 4 participating hospitals . At quarterly telephone surveys , interviewers who were blinded to treatment assignment asked patients about hospitalizations at nonparticipating hospitals ; however , we present the analysis of billing data because they measure hospitalizations independent of possibly socially acceptable responses or survey nonresponse of the patients . For functional status , we used the generic Short Form-12 ( SF-12 ) physical component score and the condition-specific Minnesota Living with Heart Failure ( MLHF ) Question naire , with both scales administered at the quarterly interviews . We measured deaths recorded in the National Death Index plus deaths reported by patients ' families for patients with no subsequent billings . Since both nurse management and usual care involved only services delivered in routine practice , the study did not monitor adverse effects . As required by the
