The effect of a combined influenza/pneumococcal immunization reminder letter.

BACKGROUND: The effect of a combined influenza and pneumococcal immunization reminder letter on increasing influenza and pneumococcal immunization rates, and the timeliness of receiving immunizations after receipt of a reminder letter, have not been examined. This study addresses these issues using a sample of new Medicare beneficiaries residing in Hawaii. METHODS: Newly enrolled Medicare beneficiaries in Hawaii from 25 September 1995 through 31 August 1996 were randomly assigned to one of three groups: Group 1, no letter (n=2144); Group 2, influenza immunization reminder letter only (n=2213); or Group 3, pneumococcal and influenza immunization reminder letter (n=2171). Health Care Financing Administration claims data were compared among groups. RESULTS: In Group 3, the influenza immunization rate increased 3.8 percentage points (n=87; p=0.017) compared with Group 1. The Group 3 pneumococcal immunization rate increased 3.5 percentage points (n=78; p<0.001) compared to Group 1 and 4.0 percentage points (n=86; p<0.001) compared to Group 2. Sixty-six beneficiaries in Group 3 received simultaneous pneumococcal and influenza immunizations, a significant difference compared to Group 1 or Group 2. Increases in immunizations were observed immediately following the reminder letters and the effect persisted for 5 to 7 weeks. CONCLUSIONS: The combination letter increased both influenza and pneumococcal immunization rates and the simultaneous administration of immunizations without detrimental effect to influenza immunization rates. A combined reminder letter is inexpensive and recommended as part of a multicomponent campaign for adult immunization.

Empiric antibiotic therapy and mortality among medicare pneumonia inpatients in 10 western states : 1993, 1995, and 1997.

STUDY OBJECTIVES: To examine the association of empiric inpatient antibiotic treatment of community-acquired pneumonia (CAP) with mortality, and whether this association varies from year to year. DESIGN: Population-based, retrospective study adjusting for demographics, comorbidities, and clinical characteristics. SETTING: Acute-care hospitals in 10 western states. PATIENTS: A group of 10,069 Medicare beneficiaries aged > or = 65 years who were hospitalized with CAP during fiscal years 1993, 1995, and 1997. MEASUREMENTS AND RESULTS: We examined the risk for mortality during the 30 days after admission to the hospital. The impact of specific antibiotic regimens varied greatly from year to year. In 1993, therapy with a macrolide plus a beta-lactam was associated with significantly lower mortality than therapy with either a beta-lactam alone (adjusted odds ratio [AOR], 0.42; 95% confidence interval [CI], 0.25 to 0.69) or other regimens that did not include a macrolide, beta-lactam, or fluoroquinolone (AOR, 0.35; 95% CI, 0.20 to 0.62). Those associations were not observed in 1995 or 1997. Lower mortality was associated with fluoroquinolone monotherapy compared with beta-lactam monotherapy in 1997 (AOR, 0.27; 95% CI, 0.07 to 0.96) and with macrolide monotherapy compared with other regimens in 1995 (AOR, 0.24; 95% CI, 0.06 to 0.93), but the number of patients who received these regimens was small. CONCLUSIONS: The inclusion of a macrolide or a fluoroquinolone in initial empiric CAP treatment was associated with improved survival, but this association varied from year to year, perhaps as a result of a temporal variation in the incidence of atypical pathogen pneumonia. Improved testing and surveillance for atypical pathogen pneumonia are needed to guide empiric therapy.

Quality of medical care delivered to Medicare beneficiaries: A profile at state and national levels.

CONTEXT: Despite condition-specific and managed care-specific reports, no systematic program has been developed for monitoring the quality of medical care provided to Medicare beneficiaries. OBJECTIVE: To create a monitoring system for a range of measures of clinical performance that supports quality improvement and provides repeated, reliable estimates at the national and state levels for fee-for-service (FFS) Medicare beneficiaries. DESIGN, SETTING, AND PARTICIPANTS: National study of repeated, cross-sectional observational data collected in 1997-1999 on all Medicare FFS beneficiaries or on a representative sample of beneficiaries with a particular condition. Data were collected using medical record abstraction for inpatient care, analysis of Medicare claims for some ambulatory services, and surveys for immunization rates. Separate samples were drawn for each topic for each state. MAIN OUTCOME MEASURES: Beneficiary patients' receipt of 24 process-of-care measures related to primary prevention, secondary prevention, or treatment of 6 medical conditions (acute myocardial infarction, breast cancer, diabetes mellitus, heart failure, pneumonia, and stroke) for which there is strong scientific evidence and professional consensus that the process of care either directly improves outcomes or is a necessary step in a chain of care that does so. RESULTS: Across all states for all measures, the percentage of patients receiving appropriate care in the median state ranged from a high of 95% (avoidance of sublingual nifedipine for patients with acute stroke) to a low of 11% (patients with pneumonia screened for pneumococcal immunization status before discharge). The median performance on an indicator is 69% (patients discharged with heart failure diagnosis who received angiotensin-converting enzyme inhibitors; diabetic patients having an eye examination in the last 2 years). Some states (particularly less populous states and those in the Northeast) consistently ranked high in relative performance while others (particularly more populous states and those in the Southeast) consistently ranked low. CONCLUSIONS: It is possible to assemble information on a diverse set of clinical performance measures that represent performance on the range of services in a health insurance program. These findings indicate substantial opportunities to improve the care delivered to Medicare beneficiaries and urgently invite a partnership among practitioners, hospitals, health plans, and purchasers to achieve that improvement.

Treatment of acute myocardial infarction and 30-day mortality among women and men.

BACKGROUND: Previous studies have suggested that women with acute myocardial infarction receive less aggressive therapy than men. We used data from the Cooperative Cardiovascular Project to determine whether women and men who were ideal candidates for therapy after acute myocardial infarction were treated differently. METHODS: Information was abstracted from the charts of 138,956 Medicare beneficiaries (49 percent of them women) who had an acute myocardial infarction in 1994 or 1995. Multivariate analysis was used to assess differences between women and men in the medications administered, the procedures used, the assignment of do-not-resuscitate status, and 30-day mortality. RESULTS: Among ideal candidates for therapy, women in all age groups were less likely to undergo diagnostic catheterization than men. The difference was especially pronounced among older women; for a woman 85 years of age or older, the adjusted relative risk was 0.75 (95 percent confidence interval, 0.68 to 0.83). Women were somewhat less likely than men to receive thrombolytic therapy within 60 minutes (adjusted relative risk, 0.93; 95 percent confidence interval, 0.90 to 0.96) or to receive aspirin within 24 hours after arrival at the hospital (adjusted relative risk, 0.96; 95 percent confidence interval, 0.95 to 0.97), but they were equally likely to receive beta-blockers (adjusted relative risk, 0.99; 95 percent confidence interval, 0.95 to 1.03) and somewhat more likely to receive angiotensin-converting-enzyme inhibitors (adjusted relative risk, 1.05; 95 percent confidence interval, 1.02 to 1.08). Women were more likely than men to have a do-not-resuscitate order in their records (adjusted relative risk, 1.26; 95 percent confidence interval, 1.22 to 1.29). After adjustment, women and men had similar 30-day mortality rates (hazard ratio, 1.02; 95 percent confidence interval, 0.99 to 1.04). CONCLUSIONS: As compared with men, women receive somewhat less aggressive treatment during the early management of acute myocardial infarction. However, many of these differences are small, and there is no apparent effect on early mortality.

Influenza vaccinations of Washington state Medicare beneficiaries seen by physiatrists in the outpatient setting in 1994.

OBJECTIVE: To compare influenza vaccination billing rates for patients seen by physiatrists with those of four other specialties: neurology, rheumatology, family practice, and internal medicine. DESIGN: Retrospective cohort analysis using Medicare billing data. PATIENTS: 234,164 Medicare outpatients seen in Washington state between September 1 and December 31, 1994. RESULTS: Based on Medicare's billing data, only 6 of 99 physiatrists ordered vaccinations, and they immunized only 159 (6%) of the patients seen. An additional 1,109 (42%) patients seen by physiatrists were vaccinated by other physicians. Physiatric patients were less likely to have been vaccinated than those seen by internists, family practitioners, or rheumatologists (p < .002), but equally likely as those seen by neurologists (p = .07). A significantly smaller percentage of physiatrists ordered vaccinations than all other specialties (p < .04). Utilizing pre-existing survey data, the misclassification rate (those immunized but not billed) was estimated at 22% of our original cohort. Thus, approximately 800 patients, one third of those seeing physiatrists, may not have been immunized. We estimated the increase in hospitalization costs to be $117 per nonvaccinated patient (total >$90,000). CONCLUSIONS: Missed opportunities for vaccination by physiatrists appear to be more frequent than in other specialties and have potentially large health and economic costs.

Quality of care, process, and outcomes in elderly patients with pneumonia.

CONTEXT: Pneumonia is a frequent cause of hospitalization and death among elderly patients, but the relationships between processes of care for pneumonia and outcomes are uncertain, making quality improvement a challenge. OBJECTIVES: To assess quality of care for Medicare patients hospitalized with pneumonia and to determine whether process of care performance is associated with lower 30-day mortality. DESIGN: Multicenter retrospective cohort study with medical record review. SETTING: A total of 3555 acute care hospitals throughout the United States. PATIENTS: A total of 14069 patients at least 65 years old hospitalized with pneumonia. MAIN OUTCOME MEASURES: Four processes of care: time from hospital arrival to initial antibiotic administration; blood culture collection before initial hospital antibiotics; blood culture collection within 24 hours of hospital arrival; and oxygenation assessment within 24 hours of hospital arrival. Associations between processes of care and 30-day mortality were determined with logistic regression analysis. RESULTS: National estimates of process-of-care performance were antibiotic administration within 8 hours of hospital arrival, 75.5% (95% confidence interval [CI], 73.1-77.9); blood cultures before antibiotics, 57.3% (95% CI, 54.5-60.1); initial blood culture collection, 68.7% (95% CI, 66.2-71.2); and initial oxygenation assessment, 89.3% (95% CI, 87.5-90.9). Lower 30-day mortality was associated with antibiotic administration within 8 hours of hospital arrival (odds ratio [OR], 0.85; 95% CI, 0.75-0.96) and blood culture collection within 24 hours of arrival (OR, 0.90; 95% CI, 0.81-1.00). State and territory performance estimates varied from 49.0% to 89.7% for antibiotics given within 8 hours and from 45.6% to 82.6% for blood cultures drawn within 24 hours. CONCLUSIONS: Administering antibiotics within 8 hours of hospital arrival and collecting blood cultures within 24 hours were associated with improved survival. The fact that states varied widely in the performance of these measures suggests that opportunities exist to improve hospital care of elderly patients with pneumonia.

Advanced perioperative nursing elective for baccalaureate students.

Recruiting baccalaureate nursing students and experienced RNs into perioperative nursing is essential if RNs are to continue their presence in surgical settings. The advanced elective described in this article is the second part of a two-elective sequence in perioperative nursing at La Salle University, Philadelphia. This collaborative program between nursing education and nursing practice contains both didactic and clinical components and broadens the exposure of basic baccalaureate and RN-baccalaureate nursing students to perioperative nursing. This experience increases graduates' marketability, provides perioperative staff members opportunities to recruit new nurses into their specialty, and creates a pool of potential perioperative staff nurses.

Epidemic carbon monoxide poisoning following a winter storm.

Hospital emergency departments were surveyed to estimate the number of patients treated for carbon monoxide (CO) poisoning after a severe winter storm disrupted electrical service in western Washington State. At least 81 persons were treated. The two main sources of CO were charcoal briquettes (54% of cases) and gasoline-powered electrical generators (40% of cases). Of the 44 persons affected by CO from burning charcoal, 40 (91%) were members of ethnic minority groups; 27 did not speak English. All persons affected by CO from generators were non-Hispanic Whites. This was the largest epidemic of storm-related CO poisoning reported in the United States. This epidemic demonstrated the need to anticipate CO poisoning as a possible consequence of winter storms in cold climates and to make preventive messages understandable to the entire population at risk, including those persons who do not understand written or spoken English.

Laser applications in orthopedics.

The use of lasers has made a significant impact on surgery. Various types of lasers are available for use in orthopedics. A successful laser program identifies perioperative considerations, applications/modalities, and reimbursement issues. As this technology expands, more clinical applications will be utilized.

Perioperative education. Transforming preceptor program into perioperative elective.

Perioperative educators must identify the specific learning needs of their staff members and develop and provide programs relevant to those needs. These programs must have administrative support, or they will fail. As perioperative nurses, we must go beyond preceptor programs. Educators in undergraduate programs need to include perioperative courses in their curricula. If a perioperative elective is included in basic nursing curricula, students will better be able to meet the needs of their profession and their patients. A perioperative elective in the nursing curriculum would expose students to perioperative nursing and recruit the interested ones. Students who choose not to work in the OR will at least have gained an understanding of aseptic technique and teamwork. Our first preceptor course was held in May 1986. As of this writing, 11 programs have been completed. In May 1990, we met our goal of participating in a perioperative elective, which shows that educational goals can be achieved with cooperative efforts between academic and clinical programs.
