Use of standing orders programs to increase adult vaccination rates.

The Advisory Committee on Immunization Practices recognizes the need for evidence-based policy to improve the delivery and receipt of immunization services recommended for adults (i.e., persons aged > or = 18 years). Two recent, systematic reviews of the health services research literature recommended standing orders programs as an effective organizational intervention to improve vaccination coverage rates among adults. This report briefly reviews the evidence on the effectiveness of standing orders programs, describes standards for program implementation, and recommends initiating these programs to improve immunization coverage in several traditional and nontraditional settings.     

Prevalence and trend in the use of hospital-based standing orders programs for influenza and pneumococcal vaccination.

BACKGROUND: In 2002, federal regulations authorized the use of standing orders programs (SOPs) for promoting influenza and pneumococcal vaccination. In 2003, the New Jersey Hospital Association conducted a demonstration project illustrating the efficacy of SOPs, and the state health department informed healthcare facilities of their benefits. We describe the prevalence of reported use of SOPs in New Jersey hospitals in 2003 and 2005 and identify hospital characteristics associated with the use of SOPs. METHODS: A survey was mailed to the directors of infection control at 117 New Jersey hospitals during the period from January to May 2005 (response rate, 90.6%). Data on hospital characteristics were obtained from hospital directories and online resources. RESULTS: The prevalence of use of SOPs for influenza vaccination was 50% (95% confidence interval [CI], 40.1%-59.9%) in 2003, and it increased to 78.3% (95% CI, 69.2%-85.7%) in 2005. The prevalence of SOP use for pneumococcal vaccination was similar. In 2005, the reported rate of use of SOPs for inpatients (influenza vaccination, 76.4%; pneumococcal vaccination, 75.5%) was significantly higher than that for outpatients (influenza vaccination, 9.4%; pneumococcal vaccination, 8.5%). Prevalence ratios for SOP use comparing acute care and non-acute care hospitals were 1.71 (95% CI, 1.2-2.5) for influenza vaccination SOPs and 1.8 for (95% CI, 1.2-2.7) pneumococcal vaccination SOPs. Acute care hospitals with a ratio of admissions to total beds greater than 36.7 reported greater use of SOPs for pneumococcal vaccination, compared with those that had a ratio of less than 36.7. CONCLUSION: The increase in the prevalence of reported use of SOPs among New Jersey hospitals in 2005, compared with 2003, was contemporaneous with SOP-related actions taken by the federal government, the state government, and the New Jersey Hospital Association. Opportunities persist for increased use of SOPs among non-acute care hospitals and for outpatients.     

Evaluation of a toolkit to introduce standing orders for influenza and pneumococcal vaccination in adults: A multimodal pilot project

Background

Immunization of adults with influenza vaccine and pneumococcal polysaccharide vaccine remains lower than recommended levels. Standing order programs (SOPs) in which non-physician medical personnel are permitted to assess an adult patient's immunization status and administer vaccines without an individual physician order are a proven method of increasing adult vaccinations, yet they are used by less than one half of primary care physicians caring for adults.

Methods

Following a national survey of primary care physicians about barriers to SOPs for adult immunizations, a SOP toolkit was developed. After review by a panel of experts, the toolkit was pilot tested in three primary care practices in a health care network with the same electronic medical record (EMR) system and low adult vaccination rates. Practice staffs were trained in the use of SOPs and the toolkit at a group meeting. This study was designed to pilot-test and evaluate the toolkit with the express intention of improving it. Three methods were used to evaluate the toolkit: (1) direct observation and interviews of each practice's staff; (2) surveys of each practice's staff; and (3) influenza and pneumococcal polysaccharide vaccine (PPV) vaccination rates.

Results

The staffs at all sites were equally likely to find the presentations and toolkit useful and did not differ in their knowledge of using SOPs for vaccination. They expressed a common set of barriers to implementing SOPs despite using the toolkit, and provided ideas for improving implementation. One site viewed SOPs in general in a more negative light and expressed that SOPs unfairly increased their workload. Vaccination rates in this site did not differ from those of the control site.

Conclusion

The evaluation suggested that the SOP toolkit should be expanded to include additional strategies to improve its applicability and effectiveness.     

Microcomputer-generated reminders. Improving the compliance of primary care physicians with mammography screening guidelines

Recent studies have documented that physician compliance with recommended periodic health screening improves with reminders to physicians. These reminders, however, are often costly to maintain and modify. This study investigates the influence of a microcomputer tickler system on the ordering of mammograms. All women (N = 1262) aged 40 years and older who made visits to an outpatient office during a 6-month period were randomly assigned to one of two groups. For the experimental group, the date of the last mammogram ordered and recorded in the clinical database was printed on the encounter form generated for each patient visit. No information regarding previous mammograms was printed for patients in the control group. Women in the experimental group were more likely to have a mammogram ordered during the study period (19% compared with 12%, P = .001) and, as a result, were more likely to be in compliance with mammography guidelines at the study's completion (27% compared with 21%, P = .011). Microcomputerized data storage and retrieval systems may help increase physicians' attention to preventive health screening recommendations.     

Economic evaluation of standing order programs for pneumococcal vaccination of hospitalized elderly patients.

BACKGROUND: Standing order programs (SOPs), which allow for vaccination without an individual physician order, are the most effective mechanism to achieve high vaccination rates. Among the suggested settings for the utilization of SOPs are hospital inpatient units, because they provide care for those most likely to benefit from vaccination. The cost-effectiveness of this approach for elderly hospitalized persons is unknown. The purpose of this study was to estimate the cost-effectiveness of SOPs for pneumococcal polysaccharide vaccine (PPV) vaccination for patients 65 years of age or older in 2 types of hospital. METHODS: In 2004, a 1,094-bed tertiary care hospital implemented a pharmacy-based SOP for PPV, and a 225-bed community hospital implemented a nursing-based SOP for PPV. Newly admitted patients 65 years of age or older were screened for PPV eligibility and then offered PPV. Vaccination rates before and after initiation of SOPs in the United States, incidence rates of invasive pneumococcal disease in the United States, and US economic data were the bases of the cost-effectiveness analyses. One-way and multivariate sensitivity analyses were conducted. RESULTS: PPV vaccination rates increased 30.5% in the tertiary care hospital and 15.3% in the community hospital. In the base-case cost-effectiveness analysis, using a societal perspective, we found that both pharmacy-based and nursing-based SOPs cost less than $10,000 per quality-adjusted life-year gained, with program costs (pharmacy-based SOPs cost $4.16 per patient screened, and nursing-based SOPs cost $4.60 per patient screened) and vaccine costs ($18.33 per dose) partially offset by potential savings from cases of invasive pneumococcal disease avoided ($12,436 per case). Sensitivity analyses showed SOPs for PPV vaccination to be cost-effective, compared with PPV vaccination without SOPs, unless the improvement in vaccination rate was less than 8%. CONCLUSION: SOPs do increase PPV vaccination rates in hospitalized elderly patients and are economically favorable, compared with PPV vaccination rates without SOPs.     

Improving rates of pneumococcal vaccination on discharge from a tertiary center medical teaching unit: A prospective intervention

Background  

Pneumococcal disease causes significant morbidity and mortality in at-risk individuals, and is complicated by emerging antibiotic resistance. An effective, safe and cost-effective vaccine is available, but despite this many patients who would benefit from pneumococcal vaccination remain unvaccinated. The purpose of this study was to determine the rates of missed opportunities to provide pneumococcal vaccination to patients being discharged from a tertiary center medical teaching unit and to determine if a nurse coordinator-based intervention would increase rates of pneumococcal vaccination prior to discharge home.     

Modelling the impact of maternal pneumococcal vaccination on infant pneumococcal disease in low-income settings

Pneumococcal disease is a leading cause of mortality in young children. The largest burden of pneumococcal disease is in the first six months of life before protection from a complete schedule of direct immunisation is possible. Maternal pneumococcal vaccination has been proposed as a strategy for protection in this period of early childhood; however, limited clinical trial data exists. In this study, we developed an age-structured compartmental mathematical model to estimate the impact of maternal pneumococcal vaccination. Our model demonstrates how maternal pneumococcal vaccination could prevent 73% (range 49–88%) of cases in those aged <1 month and 55% (range 36–66%) in those 1–2 months old. This translates to an estimated 17% reduction in deaths due to invasive pneumococcal disease in children under five. Overall, this study demonstrates the potential for maternal pneumococcal vaccination to meaningfully reduce the burden of infant pneumococcal disease, supporting the case for appropriate field-based clinical studies.     

Improving influenza vaccination performance in an HMO setting: the use of computer-generated reminders and peer comparison feedback.

We evaluated a program for improving influenza immunization performance in a health maintenance organization (HMO). The HMO implemented several interventions successively from 1984-87: a postcard reminder to members at high risk for complications of influenza, a computer-generated reminder to the physician at the time of any primary care visit by high-risk patients, performance feedback to chiefs of service, and, finally, retrospective feedback to each physician comparing his/her performance with that of the other physicians. We examined immunization rates for a group of members older than age 65, a high-risk group under age 65, and a group of diabetic members who had not been subject to the reminders (vs a group who had been covered by the program). Vaccination rates were increased in those diabetic members who received reminders. Nevertheless, among members younger and older than age 65 whose experience was observed over three flu seasons, a significant increase in vaccination rates was not achieved until physician feedback was added to the program. We conclude that each element of the reminder and feedback program has contributed to the overall increase in vaccination rates at the HMO and that effective ongoing influenza immunization programs can be implemented in practice settings with appropriate systems support.     

Vaccines4Kids: Assessing the impact of text message reminders on immunization rates in infants

The purpose of this study was to examine the effect text messages (TM) immunization reminders have on immunization rates in the first 7 months of life. This randomized-control trial enrolled 57 parent/infant dyads and had a 74% completion rate (43) at the end of the study period. The study was approved by Committee on Human Subjects at the University of Hawaii Institutional Board Review. All participants completed a demographics form and a Barriers to Immunization Survey (SHOTS survey) at the start and end of the study. Parents received TM at 4, 7, 12, 15, 20, & 23 weeks of child's age. The intervention group received immunization reminders and the control group received healthy baby messages. In the overall mixed model, between enrollment and 7 months of age, the barriers to immunizations decreased for all parents significantly. There were no significant differences in immunization rates between groups at 7 months of age. Positive responses from regarding TM interventions show this is a promising intervention, but further research is required regarding how to address behavior change and motivation for health prevention behaviors with TM.     

Significant impact of pneumococcal conjugate vaccination on pediatric parapneumonic effusion: Italy 2006–2018

Etiology and serotyping of parapneumonic effusion (PPE) and the impact of vaccination was evaluated over a 12-year period, before and after the PCV13 introduction (2011) for Italian children From 0 to 16 years of age.Five hundred and two children were evaluated; 226 blood and 356 pleural fluid samples were obtained and tested using Realtime-PCR and culture. In the pre-PCV13 era S. pneumoniae was the most frequent pathogen identified (64/90; 71.1%) with a large predominance of serotypes 1 (42.4%), 3 (23.7%), 7F (5.1%) and 19A (11.9%).The impact of vaccination, calculated on children 0–8 years of age, demonstrated a significant reduction of PPE: with an incidence rate of 2.82 (95%CL 2.32–3.41) in the pre-PCV13 era and an age-standardized rate (ASR) of 0.66 (95% CL 0.37–1.99) in the post-PCV13 era, p < 0.0001. No increase in non-PCV13 serotypes was recorded. S. pneumoniae remained the most frequent pathogen identified in the post-PCV13 era in unvaccinated children with an unchanged serotype distribution: respectively 26/66 (39.4%), 25/66 (37.9%), 5/66 (7.6%), and 4/66 (6.1%) for 1, 3, 7F and 19A. On the other hand 7F and 19A disappeared in vaccinated children and serotype 1 and 3 decreased by 91.8% and 31.5%, respectively. Realtime PCR was significantly more sensitive than culture both in pleural fluid (79.7% vs 12.5%) and in blood (17.8% vs 7.4%).In conclusion, our findings indicate that routine immunization with PCV13 has significantly reduced the burden of childhood PPE in vaccinated children, without increasing PPE due to other bacteria and without serotype shift. Moreover, the impact of PCV13 may be underestimated due to the increase in pneumococcal surveillance in Italy. Data has also shown that Real-time PCR is an essential tool to better define the etiology of PPE and to monitor vaccination plans. Longer studies will be necessary to evaluate the role of herd protection in PPE prevention.     

Improving firearm storage habits: impact of brief office counseling by family physicians

BACKGROUND: Firearm injury is the leading cause of injury-related death among youth and second leading cause of injury-related death overall in the United States. Our objective is to determine the impact of brief office counseling by family physicians on patients' firearm storage habits. METHODS: Of the 1,233 patients who completed the enrollment questionnaire, 156 (13%) reported they had guns in their household and agreed to participate in the study. Postintervention survey instruments were completed by 127 (81%) of participants. Participants received either no counseling, verbal counseling alone, or counseling and a gun safety brochure from their physician. Firearm storage habits were measured at baseline and 60 to 90 days after intervention. RESULTS: At the postintervention interview, 64% of the group receiving verbal counseling and 58% of the group receiving verbal counseling plus written information made a safe change in gun storage compared with 33% of participants in the no-intervention group (P =. 02). A logistic regression model controlling for demographics and gun ownership showed that compared with the no-intervention group, intervention participants were three times more likely to make safe changes. CONCLUSIONS: Family physicians' brief counseling efforts made a significant positive impact in the firearm storage habits of their patients. With a verbal or written recommendation, a significant improvement was observed in firearm storage.
