Partnering in CHF disease management.

Congestive heart failure mortality is increasing while medications are underprescribed. Disease management programs inform physicians, educate patients, increase monitoring, and facilitate compliance. Improved outcomes include decreased hospitalization and emergency room visits, and improved quality of life.

Polypharmacy management in Medicare managed care: changes in prescribing by primary care physicians resulting from a program promoting medication reviews.

OBJECTIVE: To examine the effects of medication reviews by primary care physicians on prescriptions written for elderly members of a Medicare managed care organization who were at risk for polypharmacy. STUDY DESIGN: Prospective study with follow-up survey. PATIENTS AND METHODS: We conducted a study in 1995 to demonstrate the prevalence of polypharmacy (defined as receiving 5 or more prescription medications during the 3-month study period) among elderly members of our managed care organization. Two years later, elderly members identified as being at risk for polypharmacy were sent a letter encouraging them to schedule a medication review with their primary care physician. Each primary care physician was provided with clinical practice guidelines on polypharmacy and patient-specific medication management reports. Patients and physicians were subsequently mailed a survey to assess the impact of the medication review program on prescribing practices. RESULTS: Of 37,372 elderly members screened, 5737 (15%) were at risk for polypharmacy. Of these, 2615 (46%) responded to the follow-up survey. Of the survey respondents, 1087 (42%) had gone to their primary care physician for a medication review. During the review, 96% of patients discussed their prescription medications and 72% discussed nonprescription medications they were taking. Twenty percent reported that their physician discontinued medications, 29% reported that the physician changed the dose of a medication, and 17% informed their physician about a new prescription or nonprescription medication they were taking. Of the 275 primary care physicians surveyed, 56 (20%) returned the questionnaire. Of these, 61% reported that the medication review program was "very" or "somewhat useful." Thirty-five percent reported discontinuing unnecessary medications, and 23% reported decreasing the frequency of dosing. Overall, 45% of physicians reported making at least one change in their prescribing to a member at risk for polypharmacy. CONCLUSIONS: Our program promoting medication reviews between primary care physicians and their elderly patients resulted in significant changes in prescribing by physicians. This type of program is likely to decrease the risk of polypharmacy among older members of a Medicare managed care organization.

Panel discussion. Data needs in cancer.

A prospective, comprehensive outcomes database was recently initiated by the National Comprehensive Cancer Network (NCCN) after a 2-year study to test data collection methods and systems. It started with data on 400 patients with newly diagnosed breast cancer at five NCCN sites, and over the next 3 years is projected to grow to include more than 12,000 patients with common cancers treated at all eligible NCCN sites. Among the goals of the database are: 1) to establish the capability to select, analyze, and report patterns of care and outcomes; 2) to allow NCCN members to assess their compliance with NCCN clinical practice guidelines and benchmark their performance against the rest of the NCCN; 3) to establish a true databased continuous quality improvement program; 4) to support clinical disease-oriented research and methodologic studies; and 5) to provide the NCCN with a vehicle for forging partnerships with others in the health-care field, such as the pharmaceutical industry, regulatory agencies, and accrediting bodies. Many of those potential partners were represented on this panel. Panelists discussed the data needs of their organizations, what they are doing to meet those needs, and how a comprehensive database will ultimately help improve patient care.

Aspirin treatment after myocardial infarction: are health maintenance organization members, women, and the elderly undertreated?

In April 1996, we surveyed 539 patients who had suffered a myocardial infarction in 1995 to determine whether the prescription and use of aspirin after myocardial infarction differs by patient age, sex, and type of health insurance. Patients who were insured through one of four health maintenance organizations in major metropolitan areas or by an indemnity plan in 40 states completed the survey. Among the 502 patients with no contraindications to use, 93.8% were prescribed aspirin. Among patients with a prescription and no subsequent contraindications to use, 96.4% were taking aspirin when surveyed. Among aspirin users, 96.5% reported taking aspirin daily. Controlling for other characteristics, 75-year-old patients were 5 percentage points less likely to receive a prescription for aspirin than were 50-year-old patients (P = 0.05). Although not significant at conventional levels, point estimates revealed a prescription rate for women that was 6 percentage points higher than that for men (P = 0.054) and a rate for health maintenance organization members that was 4 percentage points lower than that for patients with indemnity insurance (P = 0.10). Aspirin use was lower among older patients (P = 0.02) but did not differ by gender or type of insurance plan. Health maintenance organization members were just as likely to receive a prescription from a specialist as were those with indemnity insurance (P = 0.92). Based on these results, the rate of aspirin treatment after myocardial infarction may be much higher than previous studies indicate. Concerns that managed care patients and women may be undertreated are not supported by our findings. Although older patients are at risk for undertreatment, this risk is low. Once aspirin is prescribed, selfreported patient compliance with a daily regimen of aspirin is high.

Disease management interventions to improve outcomes in congestive heart failure.

This study is part of a planned 24-month, multicenter, longitudinal comparison of a comprehensive congestive heart failure (CHF) disease management program and was designed to determine effectiveness after 12 months of implementation. The impact of interventions such as telemonitoring of patients, post-hospitalization follow-up, and provider education on selected primary outcomes (hospital admission and readmission rates, length of stay, total hospital days, and emergency room utilization) in a managed care setting was evaluated. Subjects in the study included all participants in the managed care plan, as well as 149 selected program participants. The effects of the program were analyzed for pure CHF and CHF-related diagnoses, with outcomes for the third quarter of 1996 (postintervention follow-up) being compared with those for the third quarter of 1995 (preintervention baseline). Overall, the data demonstrated significantly reduced admission and readmission rates for patients with the pure CHF diagnosis. Among the entire CHF patient population, the third quarter admission rate declined 63% (P = 0.00002), and the 30-day and 90-day readmission rates declined 75% (P = 0.02) and 74% (P = 0.004), respectively. Among program participants with pure CHF diagnoses, the 30-day readmission rate was reduced to 0, and an 83% reduction occurred for both the third quarter admission (P = 0.008) and 90-day readmission (P = 0.06) rates. In addition, the average length of stay for patients with CHF-related diagnoses was significantly reduced among both plan participants (P = 0.03) and program participants (P = 0.001). Reductions were also seen in total hospital days and emergency room utilization. These data thus indicate that a comprehensive disease management program can reduce healthcare utilization not only among CHF patients in the program but also among the entire managed care plan population.

Use of ineffective or unsafe medications among members of a Medicare HMO compared to individuals in a Medicare fee-for-service program.

Adverse drug reactions and inappropriate prescribing practices are an important cause of hospitalization, morbidity, and mortality in the elderly. This study compares prescribing practices within a Medicare risk contract health maintenance organization (HMO) in 1993 and 1994 with prescribing practices for two nationally representative samples of elderly individuals predominantly receiving medical care within the Medicare fee-for-service sector. Information on prescriptions in the fee-for-service sector came from the 1987 National Medical Expenditures Survey (NMES) and the 1992 Medicare Current Beneficiary Survey (MCBS). A total of 20 drugs were studied; these drugs were deemed inappropriate for the elderly because their risk of causing adverse events exceeded their health benefits, according to a consensus panel of experts in geriatrics and pharmacology. One or more of the 20 potentially inappropriate drugs was prescribed to 11.53% of the Medicare HMO members in 1994. These medications were prescribed significantly less often to HMO members in 1994 than to individuals in the fee-for-service sector, based on information from both the 1987 NMES and the 1992 MCBS. Utilization of unsafe or ineffective medications actually decreased with increasing age in the HMO sample, with lowest rates in individuals over the age of 85. However, no relationship between age and medication use was seen in the NMES study, except for individuals over the age of 90 years. The study data support the conclusion that ineffective or unsafe medications were prescribed less often in the Medicare HMO than in national comparison groups. In fact, for the very old, who are most at risk, the use of these medications was much lower in the Medicare HMO than in the Medicare fee-for-service sector. Nevertheless, in 1994, approximately one of every nine members of this Medicare HMO received at least one such medication. Continued efforts and innovative strategies to further reduce the use of unsafe and ineffective drugs among elderly Medicare HMO members are needed.

Multiple expanded roles for nurses in urban emergency rooms. 'Emergency room nurse-practitioner'.

The increasing number of patients seeking general medical care in the emergency rooms of urban teaching hospitals creates substantial volume loads, especially in triage and in delivery of primary care. Interns perform these tasks unethusiastically and inefficiently, session physicians indifferently. Selected experienced nurses, after brief but intensive and targeted training, can successfully assume these full responsibilities with a high degree of job satisfaction.
