Exporting a successful influenza vaccination program from a teaching hospital to a community outpatient setting.

PURPOSE: To assess whether we could export a successful multifaceted influenza vaccination program from an academic medical center to a community setting. DESIGN: Pre/post study using concurrent control groups. SETTING: Clinics in a staff model Health Maintenance Organization (HMO). One urban and one suburban clinic were chosen as intervention clinics, while two similar clinics were selected as control clinics. PATIENTS: All patients aged 65 and over enrolled in the four clinics. INTERVENTIONS: An informational mailing to patients, a standing-order policy allowing nurses to administer vaccine, a vaccination reminder on daily appointment lists, and availability of walk-in visits for vaccination. Patients in the control clinics received usual care. MEASUREMENTS: Vaccination rates were determined using a validated postcard survey of 150 randomly selected patients at each clinic both at baseline (1988-89) and after the intervention (1989-90). RESULTS: The baseline vaccination rates ranged from 51.4% to 74.6%, with nearly all vaccinations taking place at the HMO. In one intervention clinic, the vaccination rate improved from 56.4% to 72.3%, P = 0.01. In the other, the baseline rate was 74.6% and did not change significantly after the intervention. There was no change in the vaccination rate in the control clinics after the intervention period. CONCLUSIONS: An influenza vaccination program that combines several organizational interventions may be successfully exported from an academic to a community setting and may serve as a useful model for others.

Frequency of adverse reactions to influenza vaccine in the elderly. A randomized, placebo-controlled trial.

Concern about side effects constitutes a major deterrent to patient compliance with influenza vaccination, yet there is a paucity of data about the occurrence of adverse reactions in the population targeted for immunization. We conducted a randomized, double-blind, crossover trial to compare the frequency of adverse reactions following administration of 1988-1989 trivalent split-antigen influenza vaccine and saline placebo. Outpatient veterans 65 years of age or over (n = 336) were recruited by mail and were randomly assigned to receive vaccine followed 2 weeks later by placebo injection or placebo followed 2 weeks later by vaccine. There was no significant difference between influenza vaccine and placebo with respect ot the proportion of subjects reporting disability or systemic symptoms.

Frequency of adverse reactions after influenza vaccination.

PURPOSE: Although concern about side effects constitutes a major deterrent to patient compliance with recommendations for influenza vaccination, there is a paucity of data about the frequency of adverse reactions to newer trivalent vaccines. Our aim was to determine the frequency of adverse reactions to influenza vaccine in older, chronically ill persons, many of whom are at high risk for influenza-related morbidity. PATIENTS AND METHODS: We conducted a telephone survey of 40% of the patients who were vaccinated at a walk-in flu shot clinic. The subjects were randomly assigned to two groups. To determine postvaccine symptom rates, Group I was interviewed seven days after vaccination. Group II was interviewed 21 days after vaccination in order to control for baseline symptom rates. Both groups were queried about fever, disability, and flu-like illness in the week preceding the interview. RESULTS: Of 816 patients selected, 650 (79.6%) completed the interview. The mean age of the subjects was 63, and more than two thirds were at risk for influenza-related morbidity. The frequencies of self-reported fever (5.3% versus 5.1%, p = 0.91) and disability (10.4% versus 9.3%, p = 0.65) were similar in the two groups. However, a significantly higher proportion of Group I subjects reported a flu-like illness compared to the Group II subjects (14.2% versus 8.7%, p = 0.03). Although Group I subjects were more likely to report flu-like illness within two days of vaccination compared to a similar time interval for Group II subjects, there was no corresponding clustering of disability after vaccination. CONCLUSION: We conclude that the overall frequency of symptoms in both groups was low; however, the absolute risk of a flu-like illness was 5.5% higher during the first week following influenza vaccination when compared with the third week after the injection. These symptoms did not result in a decreased ability to perform usual daily activities.

Achieving the national health objective for influenza immunization: success of an institution-wide vaccination program.

PURPOSE: To enhance influenza vaccination rates for high-risk outpatients at the Department of Veterans Affairs Medical Center (VAMC) in Minneapolis, Minnesota, an institution-wide immunization program was implemented during 1987. PATIENTS AND METHODS: The program consisted of: (1) a hospital policy allowing nurses to vaccinate without a signed physician's order; (2) stamped reminders on all clinic progress notes; (3) a 2-week walk-in flu shot clinic; (4) influenza vaccination "stations" in the busiest clinic areas; and (5) a mailing to all outpatients. Risk characteristics and vaccination rates for patients were estimated from a validated self-administered postcard questionnaire mailed to 500 randomly selected outpatients. For comparison, 500 patients were surveyed from each of three other Midwestern VAMCs without similar programs. RESULTS: Overall, 70.6% of Minneapolis patients were high-risk and 58.3% of them were vaccinated. In contrast, 69.9% of patients at the comparison medical centers were high-risk, but only 29.9% of them were vaccinated. CONCLUSION: The Minneapolis VAMC influenza vaccination program was highly successful and may serve as a useful model for achieving the national health objective for influenza immunization.

Open-angle glaucoma.

Open-angle glaucoma is a common cause of blindness and visual impairment, and is characterized by elevated intraocular pressure, optic nerve degeneration and visual field loss. Risk factors include increasing age, black race, positive family history and diabetes. Since many high risk individuals are seen periodically by primary care physicians, the office or clinic is a logical site for screening for open angle glaucoma. Tonometry is a useful screening maneuver, but is little used in the primary care setting. If primary care physicians can acquire the necessary skills, ophthalmoscopy may be a simple, safe and inexpensive alternative to tonometry.

Organizational strategies to improve influenza vaccine delivery. A standing order in a general medicine clinic.

Educational programs designed to modify physician compliance with influenza vaccination guidelines have yielded only modest improvement. We examined the impact of a standing order on the influenza vaccination rate in a general medicine clinic (GMC). The standing order gave GMC nurses the responsibility to identify and vaccinate high-risk elderly patients. The vaccine order rate in GMC patients seen during the one-month study period in 1986 (n = 97) was compared with the rate in GMC patients from a similar period in 1984 (n = 77) and with the rate in patients seen in three subspecialty clinics during the 1986 study period (n = 106). Comparison patients were vaccinated only by specific physician order. Following the intervention, 79 (81%) of 1986 GMC study patients had vaccination orders, vs 20 (28%) of the 1984 GMC comparison group and 31 (29%) of the 1986 subspecialty clinic comparison group. A simple organizational change consisting of a standing order profoundly improved compliance with vaccination guidelines.

Physician recognition of ophthalmoscopic signs of open-angle glaucoma: effect of an educational program.

OBJECTIVE: To evaluate a short educational intervention instructing primary care physicians in the recognition of glaucomatous changes of the optic disc. DESIGN: Comparison of performances on a pretest and a posttest consisting of fundus slides in color. SETTING: Educational conferences at two university-affiliated teaching hospitals and one staff-model health maintenance organization. SUBJECTS: Thirty-six internal medicine residents and ten practicing internists. INTERVENTION: A 20-minute slide/narration educational program, which covered diagnostic criteria for open-angle glaucoma, normal and abnormal optic disc anatomy, and funduscopic signs of open-angle glaucoma. MEASUREMENTS AND MAIN RESULTS: Following the intervention, residents showed improved sensitivity (0.76 to 0.88, p = 0.007), specificity (0.65 to 0.88, p less than 0.001), and accuracy (0.71 to 0.88, p less than 0.001). Internists showed similar increments in sensitivity, specificity, and accuracy: 0.67 to 0.86 (p = 0.01), 0.59 to 0.84 (p = 0.01), and 0.63 to 0.85 (p = 0.002), respectively. CONCLUSION: A brief educational intervention can result in meaningful improvement in physician diagnostic accuracy in recognizing ophthalmoscopic signs of open-angle glaucoma.
