Ten-year durability and success of an organized program to increase influenza and pneumococcal vaccination rates among high-risk adults

Exploring dermatologists' perspectives on vaccines in dermatology: a qualitative study

Vaccination rates among adults in the United States, including dermatology patients, remain suboptimal. Previous research has concluded that outpatient specialty offices often have administrative and patient-related barriers to administering vaccines in their clinics, however, this has never been examined specifically in dermatology. This study aims to examine dermatologists' perspectives on vaccine education in dermatology clinics, identify facilitators and barriers to vaccine administration in dermatology clinics, and explore strategies to improve vaccination rates in dermatology patients. Virtual, semi-structured interviews were conducted with board-certified dermatologists to explore their perspectives on vaccines in dermatology clinic. The Consolidated Framework for Implementation Research was used to analyze the data. Participating dermatologists were 60% female (n = 9) and 40% male (n = 6) and had a median of 7 years of clinic experience (min-max: 3-39 years). Vaccine education emerged as one of the prominent themes during the interview with dermatologists, who emphasized the importance of comprehensive vaccine education for both healthcare providers and patients. Barriers identified encompassed patient hesitancy, lack of provider knowledge, resource limitations, and logistical challenges. Dermatologists proposed solutions such as standardized protocols, improved patient communication, enhanced coordination with other healthcare providers, and increased clinic resources. These results emphasize that dermatologists can play a crucial role in advocating for and addressing preventative care through vaccine implementation and provide a high-level framework to think about implementation. Additionally, this study highlights the need for comprehensive vaccine education, systematic implementation strategies, and organizational support within dermatology clinics to improve vaccine administration for patients.

Effectiveness of an intervention to overcome influenza vaccine hesitancy in specialty clinic patients

BACKGROUND

Individuals on immunosuppressive therapies experience greater morbidity and mortality due to vaccine-preventable illnesses, but there are low rates of adherence to immunization guidelines within this population.

OBJECTIVE

To determine the effectiveness of clinician-led education, patient-centered dialogue, and immediately available immunization on influenza vaccination uptake in patients taking immunosuppressive therapies.

METHOD

We used a controlled before-and-after quasi-experimental design to evaluate our quality improvement intervention occurring from September 2019 to March 2020, with follow-up through July 2020. The study included 2 dermatology practices wherein nursing staff offered influenza vaccination during patient rooming (standard care). Within each practice, clinicians either implemented the intervention or provided only standard care. Patients received the intervention or standard care depending on the clinician they visited. Patients seen at the 2 clinics during the intervention period were included in analyses if they were taking or newly prescribed immunosuppressant medication at the time of their visit. We examined influenza immunization status for 3 flu seasons: 2017-2018 (preintervention), 2018-2019 (preintervention), and 2019-2020 (intervention).

INTERVENTION

Immunosuppressed patients initially declining an influenza vaccine were provided dermatologist-led education on the benefits of immunization. Dermatologists explored and addressed individual patients' immunization concerns. Influenza vaccination was then offered immediately postdialogue.

RESULTS

Analyses included 201 dermatology patients who were prescribed or currently taking immunosuppressive medication (intervention group [72.6%], comparison group [27.4%]). During the intervention period, 91.1% of the intervention group received influenza vaccination compared to 56.4% of the comparison group. Vaccination trends from 2018-2019 (preintervention) to 2019-2020 (intervention) differed significantly between groups (χ2 = 22.92, P < .001), with greater improvement in the intervention group. In 2019-2020, influenza vaccination was more likely in the intervention group relative to the comparison group (odds ratio: 16.22, 95% confidence interval: 5.55-47.38). In the subset of patients that had never received an influenza vaccine, influenza immunization in 2019-2020 was more common in the intervention group (75.8%, 25/33) relative to the comparison group (13.3%, 2/15, P < .001).

CONCLUSION

The intervention successfully addressed vaccine hesitancy and improved influenza immunization rates in an immunosuppressed population receiving care from a specialty clinic. Implementing a similar model across specialty clinics may improve vaccination rates for influenza, coronavirus disease 2019, and other vaccine-preventable illnesses in other populations.

Assessing influenza vaccination coverage and predictors in persons living with HIV/AIDS in Louisiana, June 2002-June 2013

Background

Despite the burden of disease and increased risk of influenza-associated morbidity and mortality among PLWHA, influenza vaccination has been understudied in this population.

Methods

We built an 11-year cohort of HIV-infected adults from medical records of PLWHA seeking care within the Louisiana State University medical system from June 2002-June 2013. Influenza vaccination uptake among PLWHA was calculated overall and for each medical facility for each influenza season. Linear regression was used to assess influenza vaccination uptake over time, both overall and by facility. Data were restricted to the final influenza season (2012-13) to assess predictors of PLWHA vaccination. Individuals were nested within medical facilities in order to assess the amount of variability in influenza vaccination rates across medical facilities.

Results

Influenza vaccination uptake among PLWHA increased over the study period (p < 0.01). The overall proportion of PLWHA vaccinated during the 2012-13 influenza season was 33.7%. 37.9% of the variability in the model occurred at the facility-level.

Conclusions

Although there was an increase in influenza vaccination within the PLWHA cohort over the course of the study, vaccination rates remained low overall. Special efforts must be made to increase vaccination uptake among PLWHA, with particular focus on those within the population who are likely to be at highest risk. The substantial variability at the facility-level indicates that there are unmeasured facility-level factors that contribute significantly to PLWHA vaccination.

A review of hospital-based interventions to improve inpatient influenza vaccination uptake for high-risk adults

BACKGROUND

Despite positive steps towards transforming immunisation understanding and practice to better incorporate adults, coverage, especially those at higher risk, is not where it should be. One way to increase uptake is to take advantage of environments outside of primary care which present easy opportunities for vaccination. This study provides a narrative review of hospital-based strategies in acute care settings aimed at improving influenza vaccination rates for adult inpatients.

METHODS

A search was conducted using Scopus, Embase and PubMed databases for articles reporting on hospital-based interventions aimed at improving influenza vaccination for adults. Studies published in English were included and descriptively analysed.

RESULTS

A total of 31 articles were included. Tested interventions included 7 standing order protocols (SOP); 4 reminders; 4 assessment/administration programs; 1 patient education program; 1 organisational-based program; 7 multi-component strategies and 8 studies comparing SOPs with other strategies. One article was included in both SOPs and reminders categories. Studies were published between 1983 and 2017 and conducted in the USA, Canada, or Australia. 18 studies reported statistical significance. Individually, each type of intervention showed success. SOPs were significantly more effective than other individual interventions, but multi-component interventions (which included an SOP) were more effective than SOPs alone. Three articles reported no significant increase in uptake attributed mainly to patient refusals, even with a strategy involving patient education. Only three studies tested provider-level strategies including hospital campaigns, hospital reward programs and interdepartmental competitions, and showed success.

CONCLUSIONS

Hospital-based interventions are an effective means of improving opportunistic inpatient vaccination. Suggestions for future research include organisational or system-based interventions; qualitative review of barriers and enablers to inpatient vaccination programs; and re-examination of outpatient settings for vaccine delivery. Most studies were not randomised or controlled; therefore, we also recommend additional RCT studies to confirm existing findings on individual strategies.

Safety of Influenza Vaccination Administered During Hospitalization

OBJECTIVE

To determine whether influenza vaccination during hospitalization increases health care utilization, fever, and infection evaluations postdischarge.

PATIENTS AND METHODS

This retrospective cohort study conducted at Kaiser Permanente Southern California included patients aged 6 months or older hospitalized in a Kaiser Permanente Southern California facility with admission and discharge dates between September 1 and March 31 of the following calendar year, from 2011 to 2014. All influenza vaccinations administered during the period of August 1 to April 30 for influenza seasons 2011-2012, 2012-2013, and 2013-2014 were identified. We compared the risk of outcomes of interest between those who received influenza vaccination during their hospitalization vs those who were never vaccinated that season or were vaccinated at other times using propensity score analyses with inverse probability of treatment weighting. Outcomes of interest included rates of outpatient and emergency department visits, readmissions, fever, and clinical laboratory evaluations for infection (urine, blood, and wound culture; complete blood cell count) in the 7 days following discharge.

RESULTS

We included in the study 290,149 hospitalizations among 255,737 patients. In adjusted analyses, we found no increased risk of readmissions (relative risk [RR], 0.88; 95% CI, 0.83-0.95), outpatient visits (RR, 0.97; 95% CI, 0.95-0.99), fever (RR, 0.80; 95% CI, 0.68-0.93), and clinical evaluations for infection (RR, 0.95; 95% CI, 0.92-0.98) among those vaccinated during hospitalization compared with those who were never vaccinated or were vaccinated at other times.

CONCLUSION

Our findings provide reassurance about the safety of influenza vaccination during hospitalization. Every contact with a health care professional, including during a hospitalization, is an opportunity to vaccinate.

Attitudes and barriers associated with seasonal influenza vaccination uptake among public health students; a cross-sectional study

Background

Although research has explored influenza vaccination uptake among medical and college students, there is a dearth of research in understanding influenza vaccination uptake and attitudes toward the vaccine among future public health practitioners. Undergraduate public health students represent future public health practitioners who may be a significant educational resource for health information, including the importance of vaccinations.

Methods

This cross-sectional study utilized survey data from 158 undergraduate public health students attending a large public university in Southern California. The survey assessed public health students’ attitudes and beliefs towards the seasonal influenza vaccine and seasonal vaccination rates among this population.

Results

Over 88% of respondents reported having been encouraged to receive the seasonal influenza vaccine, while only 43.0% reported receipt. Of the students who reported not receiving the vaccine, 49.4% believed it may give them the flu, 30.4% believed there may be dangerous side effects, and 28.9% believed they were not at risk for contracting the flu. Access to health care practitioners (OR: 3.947, 95% CI [1.308–11.906]) and social encouragement (OR: 3.139, 95% CI [1.447–6.811]) were significantly associated with receipt of the seasonal influenza vaccine.

Conclusion

As public health program curriculum includes information about seasonal influenza vaccination and 68% of the sample were seniors soon to be exiting the program with an undergraduate degree in public health education, this low seasonal influenza vaccination rate is disturbing. This study may add to the body of data demonstrating how knowledge of the vaccine does not always guarantee vaccine uptake. Results of the current study suggest that it may be beneficial to provide additional information targeted to public health students, aimed at mediating safety concerns and increasing social pressure to assist in improving vaccine acceptance and rates in this population. Maximizing seasonal influenza vaccination uptake by addressing attitudes, barriers and misperceptions may not only improve vaccination rates among public health students, but also in communities served by these future public health practitioners.

Interventions to increase influenza vaccination rates of those 60 years and older in the community

BACKGROUND

The effectiveness of interventions to increase influenza vaccination uptake in people aged 60 years and older varies by country and participant characteristics. This review updates versions published in 2010 and 2014.

OBJECTIVES

To assess access, provider, system, and societal interventions to increase the uptake of influenza vaccination in people aged 60 years and older in the community.

SEARCH METHODS

We searched CENTRAL, which includes the Cochrane Acute Respiratory Infections Group's Specialised Register, MEDLINE, Embase, CINAHL, and ERIC for this update, as well as WHO ICTRP and ClinicalTrials.gov for ongoing studies to 7 December 2017. We also searched the reference lists of included studies.

SELECTION CRITERIA

Randomised controlled trials (RCTs) and cluster-randomised trials of interventions to increase influenza vaccination in people aged 60 years or older in the community.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures as specified by Cochrane.

MAIN RESULTS

We included three new RCTs for this update (total 61 RCTs; 1,055,337 participants). Trials involved people aged 60 years and older living in the community in high-income countries. Heterogeneity limited some meta-analyses. We assessed studies as at low risk of bias for randomisation (38%), allocation concealment (11%), blinding (44%), and selective reporting (100%). Half (51%) had missing data. We assessed the evidence as low-quality. We identified three levels of intervention intensity: low (e.g. postcards), medium (e.g. personalised phone calls), and high (e.g. home visits, facilitators).Increasing community demand (12 strategies, 41 trials, 53 study arms, 767,460 participants)One successful intervention that could be meta-analysed was client reminders or recalls by letter plus leaflet or postcard compared to reminder (odds ratio (OR) 1.11, 95% confidence interval (CI) 1.07 to 1.15; 3 studies; 64,200 participants). Successful interventions tested by single studies were patient outreach by retired teachers (OR 3.33, 95% CI 1.79 to 6.22); invitations by clinic receptionists (OR 2.72, 95% CI 1.55 to 4.76); nurses or pharmacists educating and nurses vaccinating patients (OR 152.95, 95% CI 9.39 to 2490.67); medical students counselling patients (OR 1.62, 95% CI 1.11 to 2.35); and multiple recall questionnaires (OR 1.13, 95% CI 1.03 to 1.24).Some interventions could not be meta-analysed due to significant heterogeneity: 17 studies tested simple reminders (11 with 95% CI entirely above unity); 16 tested personalised reminders (12 with 95% CI entirely above unity); two investigated customised compared to form letters (both 95% CI above unity); and four studies examined the impact of health risk appraisals (all had 95% CI above unity). One study of a lottery for free groceries was not effective.Enhancing vaccination access (6 strategies, 8 trials, 10 arms, 9353 participants)We meta-analysed results from two studies of home visits (OR 1.30, 95% CI 1.05 to 1.61) and two studies that tested free vaccine compared to patient payment for vaccine (OR 2.36, 95% CI 1.98 to 2.82). We were unable to conduct meta-analyses of two studies of home visits by nurses plus a physician care plan (both with 95% CI above unity) and two studies of free vaccine compared to no intervention (both with 95% CI above unity). One study of group visits (OR 27.2, 95% CI 1.60 to 463.3) was effective, and one study of home visits compared to safety interventions was not.Provider- or system-based interventions (11 strategies, 15 trials, 17 arms, 278,524 participants)One successful intervention that could be meta-analysed focused on payments to physicians (OR 2.22, 95% CI 1.77 to 2.77). Successful interventions tested by individual studies were: reminding physicians to vaccinate all patients (OR 2.47, 95% CI 1.53 to 3.99); posters in clinics presenting vaccination rates and encouraging competition between doctors (OR 2.03, 95% CI 1.86 to 2.22); and chart reviews and benchmarking to the rates achieved by the top 10% of physicians (OR 3.43, 95% CI 2.37 to 4.97).We were unable to meta-analyse four studies that looked at physician reminders (three studies with 95% CI above unity) and three studies of facilitator encouragement of vaccination (two studies with 95% CI above unity). Interventions that were not effective were: comparing letters on discharge from hospital to letters to general practitioners; posters plus postcards versus posters alone; educational reminders, academic detailing, and peer comparisons compared to mailed educational materials; educational outreach plus feedback to teams versus written feedback; and an intervention to increase staff vaccination rates.Interventions at the societal levelNo studies reported on societal-level interventions.Study funding sourcesStudies were funded by government health organisations (n = 33), foundations (n = 9), organisations that provided healthcare services in the studies (n = 3), and a pharmaceutical company offering free vaccines (n = 1). Fifteen studies did not report study funding sources.

AUTHORS' CONCLUSIONS

We identified interventions that demonstrated significant positive effects of low (postcards), medium (personalised phone calls), and high (home visits, facilitators) intensity that increase community demand for vaccination, enhance access, and improve provider/system response. The overall GRADE assessment of the evidence was moderate quality. Conclusions are unchanged from the 2014 review.

Patient reminder and recall interventions to improve immunization rates

BACKGROUND

Immunization rates for children and adults are rising, but coverage levels have not reached optimal goals. As a result, vaccine-preventable diseases still occur. In an era of increasing complexity of immunization schedules, rising expectations about the performance of primary care, and large demands on primary care providers, it is important to understand and promote interventions that work in primary care settings to increase immunization coverage. One common theme across immunization programs in many nations involves the challenge of implementing a population-based approach and identifying all eligible recipients, for example the children who should receive the measles vaccine. However, this issue is gradually being addressed through the availability of immunization registries and electronic health records. A second common theme is identifying the best strategies to promote high vaccination rates. Three types of strategies have been studied: (1) patient-oriented interventions, such as patient reminder or recall, (2) provider interventions, and (3) system interventions, such as school laws. One of the most prominent intervention strategies, and perhaps best studied, involves patient reminder or recall systems. This is an update of a previously published review.

OBJECTIVES

To evaluate and compare the effectiveness of various types of patient reminder and recall interventions to improve receipt of immunizations.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase and CINAHL to January 2017. We also searched grey literature and trial registers to January 2017.

SELECTION CRITERIA

We included randomized trials, controlled before and after studies, and interrupted time series evaluating immunization-focused patient reminder or recall interventions in children, adolescents, and adults who receive immunizations in any setting. We included no-intervention control groups, standard practice activities that did not include immunization patient reminder or recall, media-based activities aimed at promoting immunizations, or simple practice-based awareness campaigns. We included receipt of any immunizations as eligible outcome measures, excluding special travel immunizations. We excluded patients who were hospitalized for the duration of the study period.

DATA COLLECTION AND ANALYSIS

We used the standard methodological procedures expected by Cochrane and the Cochrane Effective Practice and Organisation of Care (EPOC) Group. We present results for individual studies as relative rates using risk ratios, and risk differences for randomized trials, and as absolute changes in percentage points for controlled before-after studies. We present pooled results for randomized trials using the random-effects model.

MAIN RESULTS

The 75 included studies involved child, adolescent, and adult participants in outpatient, community-based, primary care, and other settings in 10 countries.Patient reminder or recall interventions, including telephone and autodialer calls, letters, postcards, text messages, combination of mail or telephone, or a combination of patient reminder or recall with outreach, probably improve the proportion of participants who receive immunization (risk ratio (RR) of 1.28, 95% confidence interval (CI) 1.23 to 1.35; risk difference of 8%) based on moderate certainty evidence from 55 studies with 138,625 participants.Three types of single-method reminders improve receipt of immunizations based on high certainty evidence: the use of postcards (RR 1.18, 95% CI 1.08 to 1.30; eight studies; 27,734 participants), text messages (RR 1.29, 95% CI 1.15 to 1.44; six studies; 7772 participants), and autodialer (RR 1.17, 95% CI 1.03 to 1.32; five studies; 11,947 participants). Two types of single-method reminders probably improve receipt of immunizations based on moderate certainty evidence: the use of telephone calls (RR 1.75, 95% CI 1.20 to 2.54; seven studies; 9120 participants) and letters to patients (RR 1.29, 95% CI 1.21 to 1.38; 27 studies; 81,100 participants).Based on high certainty evidence, reminders improve receipt of immunizations for childhood (RR 1.22, 95% CI 1.15 to 1.29; risk difference of 8%; 23 studies; 31,099 participants) and adolescent vaccinations (RR 1.29, 95% CI 1.17 to 1.42; risk difference of 7%; 10 studies; 30,868 participants). Reminders probably improve receipt of vaccinations for childhood influenza (RR 1.51, 95% CI 1.14 to 1.99; risk difference of 22%; five studies; 9265 participants) and adult influenza (RR 1.29, 95% CI 1.17 to 1.43; risk difference of 9%; 15 studies; 59,328 participants) based on moderate certainty evidence. They may improve receipt of vaccinations for adult pneumococcus, tetanus, hepatitis B, and other non-influenza vaccinations based on low certainty evidence although the confidence interval includes no effect of these interventions (RR 2.08, 95% CI 0.91 to 4.78; four studies; 8065 participants).

AUTHORS' CONCLUSIONS

Patient reminder and recall systems, in primary care settings, are likely to be effective at improving the proportion of the target population who receive immunizations.

Overcoming Barriers to Establishing an Inpatient Vaccination Program for Pneumococcus Using Standing Orders

Objectives:

To identify and classify barriers to establishing a standing orders program (SOP) for adult pneumococcal vaccination in acute care inpatient facilities and to provide recommendations for overcoming these roadblocks. Vaccination rates in hospitals with SOPs are generally higher than those in hospitals that require individual physician orders. The array of solutions drawn from our experience in different hospital settings should permit many types of facilities to anticipate and overcome barriers, allowing a smoother transition from initiation to successful implementation of an inpatient pneumococcal vaccination SOP.

Design:

Descriptive study of barriers and solutions encountered during implementation of a pneumococcal vaccination SOP in three hospitals of the University of Pittsburgh Medical Center Health System (UPMC) and in the scientific literature.

Setting:

As of 2004, two UPMC tertiary-care hospitals and one UPMC community hospital had incorporated SOPs into existing physician order-driven programs for inpatient vaccination with pneumococcal polysaccharide vaccine.

Results:

Barriers were identified at each step of implementation and categorized as patient related, provider related, or institutional. Based on a process of continual review and revision of our programs in response to encountered barriers, steps were taken to overcome these impediments.

Conclusions:

A strong commitment by key individuals in the facility's administration including a physician champion; ongoing, persistent efforts to educate and train staff; and close monitoring of the vaccination rate were essential for successful implementation of a SOP for pneumococcal vaccination of eligible inpatients. Legal statutes and evaluations of external hospital-rating associations regarding the effectiveness of the vaccination program were major motivating factors in its success.

Successful introduction of an underutilized elderly pneumococcal vaccine in a national immunization program by integrating the pre-existing public health infrastructure

BACKGROUND

Although pneumococcal vaccines had been recommended for the elderly population in South Korea for a considerable period of time, the coverage has been well below the optimal level. To increase the vaccination rate with integrating the pre-existing public health infrastructure and governmental funding, the Korean government introduced an elderly pneumococcal vaccination into the national immunization program with a 23-valent pneumococcal polysaccharide vaccine in May 2013.

OBJECTIVE

The aim of this study was to assess the performance of the program in increasing the vaccine coverage rate and maintaining stable vaccine supply and safe vaccination during the 20 months of the program.

METHODS

We qualitatively and quantitatively analyzed the process of introducing and the outcomes of the program in terms of the systematic organization, efficiency, and stability at the national level.

RESULTS

A staggered introduction during the first year utilizing the public sector, with a target coverage of 60%, was implemented based on the public demand for an elderly pneumococcal vaccination, vaccine supply capacity, vaccine delivery capacity, safety, and sustainability. During the 20-month program period, the pneumococcal vaccine coverage rate among the population aged ≥65 years increased from 5.0% to 57.3% without a noticeable vaccine shortage or safety issues. A web-based integrated immunization information system, which includes the immunization registry, vaccine supply chain management, and surveillance of adverse events following immunization, reduced programmatic errors and harmonized the overall performance of the program.

CONCLUSION

Introduction of an elderly pneumococcal vaccination in the national immunization program based on strong government commitment, meticulous preparation, financial support, and the pre-existing public health infrastructure resulted in an efficient, stable, and sustainable increase in vaccination coverage.

Influenza vaccination uptake and associated factors among elderly population in Hong Kong: the application of the Health Belief Model

The impact of influenza on elderly can be severe and fatal. Influenza vaccination (IV) has been shown to be effective in reducing influenza-related complications, but the IV uptake among elderly in Hong Kong remains low. This study investigated the prevalence and factors associated with IV among Chinese elderly in Hong Kong using the Health Belief Model (HBM). A total of 1101 Chinese elderly aged over 65 was randomly selected and completed a phone interview. Background information, experience of and intention to receive IV and IV-related knowledge and perceptions based on the HBM were measured. Results showed that 48.5 and 49.5% of the participants have ever been vaccinated and intended to receive IV, respectively. Female gender, having chronic disease, and participating in community activities were significantly associated with previous IV. Knowledge of the fact that IV is required every year, lower perceived side effect, IV price lower than HK$150, and recommendations from health care providers was associated with both previous IV and intention to be vaccinated in the next year. Interventions promoting IV among elderly should disseminate knowledge regarding the necessity of IV and correct misconceptions about the side effects of IV.

Estimated Human and Economic Burden of Four Major Adult Vaccine-Preventable Diseases in the United States, 2013

Low uptake of routinely recommended adult immunizations is a public health concern. Using data from the peer-reviewed literature, government disease-surveillance programs, and the US Census, we developed a customizable model to estimate human and economic burden caused by four major adult vaccine-preventable diseases (VPD) in 2013 in the United States, and for each US state individually. To estimate the number of cases for each adult VPD for a given population, we multiplied age-specific incidence rates obtained from the literature by age-specific 2013 Census population data. We then multiplied the estimated number of cases for a given population by age-specific, estimated medical and indirect (non-medical) costs per case. Adult VPDs examined were: (1) influenza, (2) pneumococcal disease (both invasive disease and pneumonia), (3) herpes zoster (shingles), and (4) pertussis (whooping cough). Sensitivity analyses simulated the impact of various epidemiological scenarios on the total estimated economic burden. Estimated US annual cost for the four adult VPDs was $26.5 billion (B) among adults aged 50 years and older, $15.3B (58 %) of which was attributable to those 65 and older. Among adults 50 and older, influenza, pneumococcal disease, herpes zoster, and pertussis made up $16.0B (60 %), $5.1B (19 %), $5.0B (19 %), and $0.4B (2 %) of the cost, respectively. Among those 65 and older, they made up $8.3B (54 %), $3.8B (25 %), $3.0B (20 %), and 0.2B (1 %) of the cost, respectively. Most (80-85 %) pneumococcal costs stemmed from nonbacteremic pneumococcal pneumonia (NPP). Cost attributable to adult VPD in the United States is substantial. Broadening adult immunization efforts beyond influenza only may help reduce the economic burden of adult VPD, and a pneumococcal vaccination effort, primarily focused on reducing NPP, may constitute a logical starting place. Sensitivity analyses revealed that a pandemic influenza season or change in size of the US elderly population could increase these costs dramatically.

Influenza and Pneumococcal Vaccine Coverage Rates among Patients Admitted to a Teaching Hospital in South Korea

Background

Influenza and pneumococcal vaccinations can reduce morbidity and mortality especially in the elderly and patients with chronic medical disease. The purpose of this study was to estimate vaccination coverage of these populations in a hospital setting.

Materials and Methods

We conducted a cross-sectional, descriptive study involving adult patients admitted to a 1,000-bed teaching hospital on April 15, 2013. We ascertained the information on whether the patient had received influenza vaccination within a year prior to admission or pneumococcal vaccination by interviewing each patient.

Results

A total of 491 eligible patients aged ≥50 years or with chronic medical illnesses were analyzed. The overall vaccination rate for influenza was 57.2%, and that of pneumococcus was 17.6% among the vaccine-eligible subjects. Influenza/pneumococcal vaccination rates of patients by disease were 62.8%/17.2% for diabetes, 53.3%/15.6% for malignancy, 67.6%/23.5% for chronic pulmonary disease, 66.7%/15.3% for chronic cardiovascular disease, 68.7%/26.9% for chronic renal disease, and 51.2%/18.6% for chronic hepatic disease. Young adult patients with chronic medical conditions were consistently less likely to receive influenza and pneumococcal vaccines irrespective of the underlying disease.

Conclusion

The influenza and pneumococcal vaccine coverage rates among hospitalized patients were low in South Korea. This was especially the case for young adult patients with chronic medical illnesses.

A review of acute care interventions to improve inpatient pneumococcal vaccination

OBJECTIVE

To provide a narrative review of the impact of provider-based, organizational strategies in acute care settings to improve pneumococcal vaccination rates among patients over 65, and 2-64 years with high risk medical conditions.

METHODS

A search was conducted using MEDLINE, Scopus, CINAHL and Web of Science databases for hospital-based, inpatient studies which evaluated strategies to improve pneumococcal vaccination rates. Studies published in English from 1983 to 2013 were included. Data abstracted was analyzed descriptively.

RESULTS

A total of 35 studies were included; 15 evaluated physician reminders (e.g. chart or paper reminders, pre-printed orders (PPOs), computerized reminders, checklists) and 21 standing orders programs (SOPs). The most common study design was pre/post, and only 7 studies had a control group. Overall, 32 studies showed improvements in the rate of pneumococcal vaccination following intervention (19 statistically significant), with reminders showing 29-74% immunization rate, PPCO 5-42%, and SOPs 3.4-78%.

CONCLUSION

Hospital-based interventions improve pneumococcal vaccination in older adults and younger individuals at risk. Although this review found that more success was observed with SOPs the impact on immunization rates in eligible patients varied significantly. Thus, high quality, randomized-controlled studies are required to determine the effect of each type of institutional immunization strategy.

Interventions to increase influenza vaccination rates of those 60 years and older in the community

BACKGROUND

The effectiveness of interventions to increase the uptake of influenza vaccination in people aged 60 and older is uncertain.

OBJECTIVES

To assess access, provider, system and societal interventions to increase the uptake of influenza vaccination in people aged 60 years and older in the community.

SEARCH METHODS

We searched CENTRAL (2014, Issue 5), MEDLINE (January 1950 to May week 3 2014), EMBASE (1980 to June 2014), AgeLine (1978 to 4 June 2014), ERIC (1965 to June 2014) and CINAHL (1982 to June 2014).

SELECTION CRITERIA

Randomised controlled trials (RCTs) of interventions to increase influenza vaccination uptake in people aged 60 and older.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed study quality and extracted influenza vaccine uptake data.

MAIN RESULTS

This update identified 13 new RCTs; the review now includes a total of 57 RCTs with 896,531 participants. The trials included community-dwelling seniors in high-income countries. Heterogeneity limited meta-analysis. The percentage of trials with low risk of bias for each domain was as follows: randomisation (33%); allocation concealment (11%); blinding (44%); missing data (49%) and selective reporting (100%). Increasing community demand (32 trials, 10 strategies)The interventions with a statistically significant result were: three trials (n = 64,200) of letter plus leaflet/postcard compared to letter (odds ratio (OR) 1.11, 95% confidence interval (CI) 1.07 to 1.15); two trials (n = 614) of nurses/pharmacists educating plus vaccinating patients (OR 3.29, 95% CI 1.91 to 5.66); single trials of a phone call from a senior (n = 193) (OR 3.33, 95% CI 1.79 to 6.22), a telephone invitation versus clinic drop-in (n = 243) (OR 2.72, 95% CI 1.55 to 4.76), a free groceries lottery (n = 291) (OR 1.04, 95% CI 0.62 to 1.76) and nurses educating and vaccinating patients (n = 485) (OR 152.95, 95% CI 9.39 to 2490.67).We did not pool the following trials due to considerable heterogeneity: postcard/letter/pamphlets (16 trials, n = 592,165); tailored communications (16 trials, n = 388,164); customised letter/phone-call (four trials, n = 82,465) and client-based appraisals (three trials, n = 4016), although several trials showed the interventions were effective. Enhancing vaccination access (10 trials, six strategies)The interventions with a statistically significant result were: two trials (n = 2112) of home visits compared to clinic invitation (OR 1.30, 95% CI 1.05 to 1.61); two trials (n = 2251) of free vaccine (OR 2.36, 95% CI 1.98 to 2.82) and one trial (n = 321) of patient group visits (OR 24.85, 95% CI 1.45 to 425.32). One trial (n = 350) of a home visit plus vaccine encouragement compared to a home visit plus safety advice was non-significant.We did not pool the following trials due to considerable heterogeneity: nurse home visits (two trials, n = 2069) and free vaccine compared to no intervention (two trials, n = 2250). Provider- or system-based interventions (17 trials, 11 strategies)The interventions with a statistically significant result were: two trials (n = 2815) of paying physicians (OR 2.22, 95% CI 1.77 to 2.77); one trial (n = 316) of reminding physicians about all their patients (OR 2.47, 95% CI 1.53 to 3.99); one trial (n = 8376) of posters plus postcards (OR 2.03, 95% CI 1.86 to 2.22); one trial (n = 1360) of chart review/feedback (OR 3.43, 95% CI 2.37 to 4.97) and one trial (n = 27,580) of educational outreach/feedback (OR 0.77, 95% CI 0.72 to 0.81).Trials of posters plus postcards versus posters (n = 5753), academic detailing (n = 1400) and increasing staff vaccination rates (n = 26,432) were non-significant.We did not pool the following trials due to considerable heterogeneity: reminding physicians (four trials, n = 202,264) and practice facilitators (three trials, n = 2183), although several trials showed the interventions were effective. Interventions at the societal level We identified no RCTs of interventions at the societal level.

AUTHORS' CONCLUSIONS

There are interventions that are effective for increasing community demand for vaccination, enhancing access and improving provider/system response. Heterogeneity limited pooling of trials.

Trends in racial/ethnic disparities in influenza vaccination coverage among adults during the 2007-08 through 2011-12 seasons

BACKGROUND

Annual influenza vaccination is recommended for all persons aged ≥6 months. The objective of this study was to assess trends in racial/ethnic disparities in influenza vaccination coverage among adults in the United States.

METHODS

We analyzed data from the 2007-2012 National Health Interview Survey (NHIS) and Behavioral Risk Factor Surveillance System (BRFSS) using Kaplan-Meier survival analysis to assess influenza vaccination coverage by age, presence of medical conditions, and racial/ethnic groups during the 2007-08 through 2011-12 seasons.

RESULTS

During the 2011-12 season, influenza vaccination coverage was significantly lower among non-Hispanic blacks and Hispanics compared with non-Hispanic whites among most of the adult subgroups, with smaller disparities observed for adults age 18-49 years compared with other age groups. Vaccination coverage for non-Hispanic white, non-Hispanic black, and Hispanic adults increased significantly from the 2007-08 through the 2011-12 season for most of the adult subgroups based on the NHIS (test for trend, P < .05). Coverage gaps between racial/ethnic minorities and non-Hispanic whites persisted at similar levels from the 2007-08 through the 2011-12 seasons, with similar results from the NHIS and BRFSS.

CONCLUSIONS

Influenza vaccination coverage among most racial/ethnic groups increased from the 2007-08 through the 2011-12 seasons, but substantial racial and ethnic disparities remained in most age groups. Targeted efforts are needed to improve coverage and reduce these disparities.

Effectiveness of hospital-based postpartum procedures on pertussis vaccination among postpartum women

OBJECTIVE

Pertussis causes significant morbidity among adults, children, and especially infants. Since 2006, pertussis vaccination has been recommended for women after delivery. We conducted a prospective, controlled evaluation of in-hospital postpartum pertussis vaccination of birth mothers from October 2009 through July 2010 to evaluate the effectiveness of hospital-based procedures in increasing postpartum vaccination.

STUDY DESIGN

The intervention and comparison hospitals are private community facilities, each with 2000-6000 births/year. At the intervention hospital, physician opt-in orders for tetanus toxoid, reduced diphtheria toxoid and acellular pertussis vaccine (Tdap) before discharge were implemented in November 2009, followed by standing orders in February 2010. The comparison hospital maintained standard practice. Randomly selected hospital charts of women after delivery were reviewed for receipt of Tdap and demographic data. We evaluated postpartum Tdap vaccination rates and conducted multivariate analyses to evaluate characteristics that are associated with vaccination. We reviewed 1264 charts (658 intervention hospital; 606 comparison hospital) from women with completed deliveries.

RESULTS

Tdap postpartum vaccination was 0% at both hospitals at baseline. In the intervention hospital, the introduction of the opt-in order was followed by an increase in postpartum vaccination to 18%. The introduction of the standing order approach was followed by a further increase to 69% (P < .0001). No postpartum Tdap vaccinations were documented in the comparison hospital. Postpartum Tdap vaccination in the intervention hospital did not differ by demographic characteristics.

CONCLUSION

In-hospital ordering procedures substantially increased Tdap vaccination coverage in women after delivery. Opt-in orders increased coverage that increased substantially with standing orders.

Seasonal influenza vaccination coverage among adult populations in the United States, 2005-2011

The most effective strategy for preventing influenza is annual vaccination. We analyzed 2005-2011 data from the National Health Interview Survey (NHIS), using Kaplan-Meier survival analysis to estimate cumulative proportions of persons reporting influenza vaccination in the 2004-2005 through 2010-2011 seasons for persons aged ≥18, 18-49, 50-64, and ≥65 years, persons with high-risk conditions, and health-care personnel. We compared vaccination coverage by race/ethnicity within each age and high-risk group. Vaccination coverage among adults aged ≥18 years increased from 27.4% during the 2005-2006 influenza season to 38.1% during the 2010-2011 season, with an average increase of 2.2% annually. From the 2005-2006 season to the 2010-2011 season, coverage increased by 10-12 percentage points for all groups except adults aged ≥65 years. Coverage for the 2010-2011 season was 70.2% for adults aged ≥65 years, 43.7% for adults aged 50-64 years, 36.7% for persons aged 18-49 years with high-risk conditions, and 55.8% for health-care personnel. In most subgroups, coverage during the 2010-2011 season was significantly lower among non-Hispanic blacks and Hispanics than among non-Hispanic whites. Vaccination coverage among adults under age 65 years increased from 2005-2006 through 2010-2011, but substantial racial/ethnic disparities remained in most age groups. Targeted efforts are needed to improve influenza vaccination coverage and reduce disparities.

Obstetrical Healthcare Personnel's Attitudes and Perceptions on Maternal Vaccination with Tetanus-Diphtheria-Acellular Pertussis and Influenza

Objectives. To assess perceptions of obstetrical healthcare personnel (HCP) regarding routine delivery of Tdap and influenza vaccines to pregnant and postpartum women and identify perceived barriers to vaccination. Methods. Anonymous Web-based survey of obstetricians and nurses caring for pregnant and/or postpartum women. Results. We contacted 342 HCP and received 163 (48%) completed surveys (33/142 (23%) obstetricians, 130/200 (65%) nurses). Among obstetricians, 72% and 63% thought it was “beneficial” to immunize postpartum women against influenza and pertussis, respectively. Only 8% reported vaccinating >75% of pregnant women in their care against influenza. Similarly, <1% of obstetricians reported vaccinating against pertussis. Of all HCP surveyed, 92% and 58% were familiar with ACIP recommendations for influenza and pertussis, respectively. Reported perceived barriers included patient refusal to be vaccinated, reimbursement difficulties, and discomfort in providing vaccine education. Ninety-four percent of respondents agreed that standing orders would be helpful to ensure postpartum vaccination. Conclusions. HCP were less familiar with ACIP recommendations for Tdap compared to influenza vaccines. Substantial discrepancy existed between perceived benefit of vaccination and reported immunization practices. Most identified barriers could be addressed with provider training; however, other barriers require review and changes in systematic policies related to vaccine reimbursement.

Improving rates of herpes zoster vaccination with a clinical decision support system in a primary care practice

RATIONALE

Herpes zoster (shingles) is a localized neurocutaneous eruption of blisters caused by reactivation of the varicella zoster virus. The cost of care for herpes zoster and its complications is estimated at $1.1 billion. The Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices recommends a one-time dose of the vaccine for adults aged 60 years or older. Despite that recommendation, utilization of the vaccine is very low. One way to boost the delivery of preventive services such as vaccinations is with a computerized clinical decision support system. Our study found that the herpes zoster vaccination rate increased significantly after the implementation of such a system.

AIMS

To study utilization of herpes zoster vaccine before and after the implementation of a web-based clinical decision support software solution in a primary care practice.

METHODS

Billing data was utilized to determine number of herpes zoster vaccination administered to patients for a 12-month period during the implementation of the software solution.

RESULTS

The utilization of vaccinations improved from 63 to 117 (53.8% increase) for one primary care practice and from 54 to 127 (42.5% increase) in the other primary care practice.

CONCLUSION

Herpes zoster vaccination rate significantly improved with implementation of a web-based clinical decision support system.

Knowledge, attitudes, and clinical practice of rheumatologists in vaccination of the at-risk rheumatology patient population

BACKGROUND

Patients with inflammatory arthritis are at increased risk of infection. Much of the burden of infection in this population is vaccine preventable. A number of international rheumatology organizations have published expert recommendations for vaccination in adult patients. Despite this, reported vaccination rates remain low among patients with inflammatory arthritis.

OBJECTIVES

We sought to establish the knowledge, attitudes, and clinical practice of rheumatologists with respect to vaccination.

METHODS

Rheumatologists practicing in Ireland in 2009 were surveyed by postal questionnaire. Data collected was entered into Microsoft Excel and statistical analysis was carried out using SPSS18 software.

RESULTS

Eighty (100%) practicing rheumatologists were surveyed. Response rate was 55% (44/80). Of those surveyed, 57% (25/44) had no written departmental vaccination guidelines. Although 90% of those surveyed agreed that the responsibility for ensuring vaccine compliance rests with health professionals, only 5% considered that the rheumatology clinic was the best setting in which to accomplish this. Half (50%, n = 22) of practicing rheumatologists do not inquire about vaccination history in the clinic, with a minority (9%, n = 4) recording vaccination history in their clinical notes. A significant percentage of rheumatologists do not perform screening about prior vaccination before initiation of either anti-tumor necrosis factor (34%) or disease-modifying antirheumatic disease (42%) therapy. Moreover, 57% (n = 25) considered the responsibility for vaccination the domain of the patients' general practitioners with the favored strategy to improve vaccine compliance being led by the primary care physicians (48%, n = 21).

CONCLUSIONS

The practice of Irish rheumatologists with regard to vaccination in this survey was suboptimal. Most neither recommend nor record vaccination history in their clinical notes, with the majority feeling that the rheumatology clinic is not the appropriate setting in which to target strategies to improve vaccine compliance. Although a more proactive role needs to be taken by rheumatologists as the principal prescribers of immunosuppressive therapy on this issue, our survey respondents suggest that strategies to improve vaccine uptake should be developed outside the rheumatology clinic and, in particular, involve primary care. The circulation of currently available international guidelines on vaccination specific for rheumatology patients to primary care physicians should be used to inform practices to ensure improved vaccine compliance.

Delivering influenza vaccine to high-risk adults: subspecialty physician practices

Influenza is responsible for significant morbidity and mortality in the United States. Despite long-standing national recommendations, only 47% of adults with a high-risk condition received the influenza vaccine in 2009-2010. Subspecialty practices provide a significant portion of ambulatory care visits for high-risk adults and understanding their role in the immunization infrastructure may increase immunization rates, decrease public health burden, and reduce influenza-associated disease. A cross-sectional survey of cardiology, pulmonology, and obstetrics/gynecology practices was conducted to assess influenza vaccination practices, plans, patient acceptance, frustrations, and reasons for not vaccinating. It was found that 51% of respondents planned to vaccinate patients. Plans differed significantly by practice type. Practices that do not vaccinate generally recommend vaccination and refer patients to public health clinics, primary care, and pharmacies.   Administrative and patient-related barriers affected most practices, but practices that vaccinate were able to overcome these barriers. Improvements in vaccination may be addressed by adapting practice support services for subspecialty practices.

New opportunity for vaccinating older people: well-child clinic visits

BACKGROUND

Streptococcus pneumoniae causes considerable morbidity and mortality in the elderly. As aging of the population is making the health of the elderly a universal priority, preventive measures, such as vaccination, will become increasingly important.

METHODS

We designed a prospective interventional study to determine whether recommendations to vaccinate grandparents of children attending well-child clinics would increase the pneumococcal vaccination rate in the elderly. Children younger than 5 years of age, attending a university well-child clinic from 1 May to 31 September 2008 who had grandparents over 65 years of age were eligible. A survey including the questions about the demographic characteristics of children, their parents and grandparents over 65 was carried out by face-to-face interview with the parents. High-risk medical conditions and vaccination history of grandparents was also noted and the benefits and necessity of pneumococcal vaccination (23vPPV) for the elderly was emphasized. Four months later these families were contacted to determine whether this intervention had increased the pneumococcal vaccination rates of the elderly.

RESULTS

Information was obtained from 938 grandparents of 545 children. Before the interview, among all grandparents, only 0.9% were vaccinated with 23vPPV. Four months after this intervention, immunization coverage increased to 19.1%. The sex of the grandchild (OR: 1.99) and previous hepatitis B or influenza immunization of the grandparents (OR: 2.73) were the significant parameters accounting for higher immunization rates.

CONCLUSION

Reminding elderly grandparents about vaccines in well-child clinics could be an opportunity in this field.

The use of a mandatory best practice reminder in the electronic record improves influenza vaccination rate in a pediatric rheumatology clinic

Purpose

Children with rheumatic disease, who are infected with influenza, have an increased rate of complications. These complications can be reduced by improving the flu vaccination rate. This paper's aim is to document the authors' purpose of increasing the influenza vaccination rate through information technology (IT) intervention in this high risk population of patients.

Design/methodology/approach

The authors retrospectively reviewed the electronic health records (EHR) of three yearly cohorts (2007, 2008, and 2009) of rheumatology clinic patients from a large pediatric hospital for evidence of influenza vaccination. They introduced an automatic best practice reminder intervention in patients' EHR from September 2009 to April 2010. Using Clarity Report Write for EPIC, each chart was examined for evidence of influenza vaccination to test for vaccination rate difference among the cohorts. The authors employed logistic regression equations to control for possible confounders using SAS 9.1.3.

Findings

There was a significant difference in the probability of being vaccinated before and after intervention (p value <0.0001).The vaccination rate increased from 5.9 percent in 2007, 7.8 percent in 2008 and to 25.5 percent in 2009. During all three years, individual attending's contribution and ethnicity of patients had significant effects on vaccination rate. Confounders such as age, sex, insurance status and distance travelled from clinic had no effect on the vaccination rate.

Originality/value

EHR‐embedded information in past studies has been only modestly effective in improving care for many chronic conditions. The automatic best practice reminder for flu‐vaccine appears to be effective for changing physician's behaviors and improving the vaccination rate in rheumatology clinics.

Recent hospitalization for non-coronary events and use of preventive medications for coronary artery disease: an observational cohort study

Background

High-quality systems have adopted a comprehensive approach to preventive care instead of diagnosis or procedure driven care. The current emphasis on prescribing medications to prevent complications of coronary artery disease (CAD) at discharge following an acute coronary syndrome (ACS) may exclude high-risk patients who are hospitalized with conditions other than ACS.

Methods

Among a sample of patients with CAD treated at Veterans Affairs medical centers between January, 2005 and November, 2006, we investigated whether recent non-ACS hospitalization was associated with prescriptions of preventive medications as compared with patients recently hospitalized with ACS.

Results

Of 13,211 patients with CAD, 58% received aspirin, 70% β-blocker, 60% angiotensin-converting enzyme inhibitor (ACE-I) or angiotensin II receptor blocker (ARB), and 65% lipid-lowering therapy. Twenty-five percent of eligible patients were receiving all four medications. Having been hospitalized for a non-ACS event in the prior 6 months did not substantially affect the adjusted proportion on preventive medications. In contrast, among patients hospitalized for ACS in the prior 6 months, the adjusted proportion prescribed aspirin was 21% higher (p < 0.001), β-blocker was 14% higher (p < 0.001), ACE-I or ARB was 9% higher (p < 0.001), lipid therapy was 12% higher (p < 0.001), and prescribed all four medications was 18% higher (p < 0.001) than among patients hospitalized for ACS more than 2 years earlier.

Conclusions

Being hospitalized for a non-ACS condition did not appear to influence preventive medication use among patients with CAD and represents a missed opportunity to improve patient care. The same protocols employed to improve use of preventive medications in patients discharged for ACS might be extended to CAD patients discharged for other conditions as well.

Interventions to increase influenza vaccination rates of those 60 years and older in the community

BACKGROUND

Although the evidence to support influenza vaccination is poor, it is promoted by many health authorities. There is uncertainty about the effectiveness of interventions to increase influenza vaccination rates in those 60 years or older.

OBJECTIVES

To assess effects of interventions to increase influenza vaccination rates in those 60 or older.

SEARCH STRATEGY

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2010, issue 3), containing the Cochrane Acute Respiratory Infections Group's Specialized Register, MEDLINE (January 1950 to July 2010), PubMed (January 1950 to July 2010), EMBASE (1980 to 2010 Week 28), AgeLine (1978 to July 2010), ERIC (1965 to July 2010) and CINAHL (1982 to July 2010).

SELECTION CRITERIA

Randomized controlled trials (RCTs) to increase influenza vaccination rates in those aged 60 years and older, recording influenza vaccination status either through clinic records, billing data or local/national vaccination registers.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed study quality and extracted data.

MAIN RESULTS

Forty-four RCTs were included. All included RCTs studied seniors in the community and in high-income countries. No RCTs of society-level interventions were included. Heterogeneity was marked and meta-analysis was limited. Only five RCTs were graded at low and six at moderate risk of bias. They included three of 13 personalized postcard interventions (all three with the 95% confidence interval (CI) above unity), two of the four home visit interventions (both with 95% CI above unity, but one a small study), three of the four reminder to physicians interventions (none with 95% CI above unity) and three of the four facilitator interventions (one with 95% CI above unity, and one P < 0.01). The other 33 RCTs were at high risk of bias and no recommendations for practice can be drawn.

AUTHORS' CONCLUSIONS

Personalized postcards or phone calls are effective, and home visits, and facilitators, may be effective. Reminders to physicians are not. There is insufficient good evidence for other interventions.

Analysis of hospitalizations for COPD exacerbation: opportunities for improving care

BACKGROUND

Little is known about the actual treatment of patients with chronic obstructive pulmonary disease (COPD), either in the inpatient or outpatient settings. We hypothesized that there are substantial opportunities for improvement in adherence with current guidelines and recommendations.

METHODS

We reviewed the medical records of all patients hospitalized with acute exacerbation of COPD between January 2005 and December 2006 at 5 New York City hospitals.

RESULTS

There were 1285 unique patients with 1653 hospitalizations. Of these 1653, 83% were for patients with a prior history of COPD and 368 (22%) represented repeat admissions during our study period. The majority were treated during their hospitalization with a combination of systemic steroids (85%), bronchodilators (94%) and antibiotics (80%). There were 59 deaths (3.6%). Smoking cessation counseling was offered to 48% of active smokers. Influenza and pneumococcal vaccines were administered to half of eligible patients. On discharge, only 46.0% were prescribed maintenance bronchodilators and 24% were not prescribed any inhaled therapy. Even in the 226 unique patients (17.6%) readmitted at least once during course of the study, on discharge only 44.7% were prescribed maintenance bronchodilators and 23% were not prescribed any regular inhaled therapy.

CONCLUSIONS

Patients hospitalized with acute exacerbation of COPD generally receive adequate hospital care, but there may be opportunities to improve care pharmacologically and with smoking cessation counseling and vaccination during and after hospitalization.

Cross-sectional analysis of hospitalist prevalence and quality of care in California

BACKGROUND

Hospital leaders usually provide financial support to hospitalists groups, often with an expectation of improved performance on publicly reported quality metrics. Whether the presence of hospitalists is associated with differences in hospital-level performance is unknown.

OBJECTIVE

Assess the relationship between hospitalist prevalence and quality performance.

DESIGN

Cross-sectional study.

PARTICIPANTS

A total of 208 California hospitals participating in a voluntary reporting initiative.

INTERVENTION

Survey of hospital personnel with knowledge of the utilization of hospitalists for patient care.

MEASUREMENTS

Sixteen publicly reported quality process measures across 3 medical conditions: acute myocardial infarction (AMI); congestive heart failure (CHF); and pneumonia. Using multivariable models, we assessed the relationship between the presence of hospitalists and the percentage of missed quality opportunities for each process measure.

RESULTS

Of 208 eligible hospitals, 170 (82%) had hospitalist services. After adjustment, hospitals with hospitalists had similar performance for cardiac and pneumonia measures assessed at admission and fewer missed processes for CHF measures assessed at discharge. Among sites with hospitalists, every 10% increase in the estimated percentage of patients admitted by hospitalists was associated with 0.5% fewer (P < 0.001) missed quality opportunities for AMI at admission, and 0.6% (P < 0.001), 0.5% (P = 0.004), and 1.5% (P = 0.006) fewer missed quality opportunities for AMI, CHF, and pneumonia assessed at discharge, respectively.

CONCLUSIONS

The presence of hospitalists in California was associated with modest improvements in performance on publicly reported process measures. Whether hospitalists directly improve quality or simply reflect a hospital's level of investment in quality remains a subject for future study.

Using quantitative and qualitative approaches to understand racial disparities in adult vaccination

BACKGROUND

One proposed explanation for the persistence of racial disparities in adult immunizations is that minority patients receive primary care at practices that differ substantively from practices where white patients receive care. This study used both quantitative and qualitative methods to assess physician and practice factors contributing to disparities in a sample of inner-city, urban, and suburban practices in low to moderate income neighborhoods.

METHODS

Pneumococcal polysaccharide vaccine (PPV) and influenza vaccination rates were determined from medical record review in a sample of 2021 elderly (aged > or = 65 years) patients. Their physicians were surveyed about office systems for adult immunizations and structured observations of practice physical features, and operations were conducted. Case studies of practices with lowest and highest rates and the largest racial disparities are presented.

RESULTS

Overall, weighted PPV vaccination rate was 60%, but rates differed significantly by race (65.8% for whites vs 36.5% for minorities, P < .001 by stratified Cochran-Mantel-Haenszel test). Two of 6 minority panels had PPV rates less than 20%. Overall, weighted influenza vaccination rate, as measured by receipt of the vaccine in 3 of the 5 most recent seasons, was 51.9%, but rates also differed significantly by race (55.6% for whites vs 36.2% for minorities, P < .03, by stratified Cochran-Mantel-Haenszel test).

CONCLUSIONS

Low rates in 2 minority panels, racial disparity between minorities and whites in mixed panels, and between-panel variation in rates contributed to the overall differences in vaccination rates by race.

Understanding adult vaccination in urban, lower-socioeconomic settings: influence of physician and prevention systems

PURPOSE

Vaccination rates for pneumococcal polysaccharide vaccine (PPV) and influenza vaccine are relatively low in disadvantaged urban populations. This study was designed to assess which physician and practice characteristics might explain differences in rates across physicians.

METHODS

PPV and influenza vaccination rates were determined for 2,021 patients aged 65 years and older receiving care from 30 physicians in 17 practices surveyed about their office systems for providing adult immunizations. Hierarchical linear modeling (HLM) analyses were used to examine the relationships among vaccination rates, patient-level characteristics, and physician variables.

RESULTS

Overall, the weighted PPV vaccination rate was 60.0% and varied widely across physicians (range, 11%-98%). At the patient level in HLM, patient race (P=.01) and age (P = .02), but not neighborhood income, were associated with PPV status. By linking physician survey data with PPV rates, we found the best pair of physician variables to be "reported time spent with patients for a well visit" (P = .01) and "use of enhanced immunization documentation" (P=.10). The overall influenza vaccination rate was 51.9% (range, 22%-96%). Patient race (P=.003) and age (P = .002) were associated with influenza vaccination. The pair of physician variables with the strongest association with influenza vaccination was "use of standing orders" (P <.001) and "average observed physician examination room time," regardless of visit type (P=.02).

CONCLUSIONS

Vaccination rates vary widely in urban settings and are associated with practice characteristics such as time spent with patients and, for influenza vaccine, use of standing orders.

Alternative vaccination locations: who uses them and can they increase flu vaccination rates?

Since many unvaccinated individuals do not regularly contact the traditional health care system, we sought to determine the role that alternative vaccination locations (e.g., workplaces and retail clinics) could play in increasing influenza vaccination coverage. Between February 14, 2008 and March 10, 2008, a 25-question influenza vaccine questionnaire was administered to a nationally representative, stratified sample of panelists. Our results found that while alternative locations are covering some segments not captured by the traditional health care system (e.g., younger, working, white individuals in metropolitan areas), they are not serving many other segments (e.g., minority, rural, or lower income patients).

Association of standing-order policies with vaccination rates in dialysis clinics: a US-based cross-sectional study

BACKGROUND

Patients with end-stage renal disease are at increased risk of morbidity and mortality because of infection. Quality improvement efforts for this patient population include assessment of institutional policies and practices that may increase vaccination rates for influenza, hepatitis B, and pneumococcal disease.

STUDY DESIGN

A survey of vaccination practices, beliefs, and attitudes was sent to all dialysis centers in End-Stage Renal Disease Networks 6, 11, and 15.

SETTING & PARTICIPANTS

Of 1,052 dialysis facilities considered, 683 returned the survey, reported vaccination rates for 2005 to 2006, and had 20 or more patients.

PREDICTOR OR FACTOR

Standing-order policy of the dialysis facility, categorized as facility-wide orders, preprinted admission orders for each patient (chart orders), physician-specific orders, and individual orders.

OUTCOMES

Vaccination rates for influenza, hepatitis B (full or partial series), hepatitis B, and pneumococcal vaccine.

MEASUREMENTS

Patient vaccination, given at or outside the center.

RESULTS

Overall vaccination rates were 76% +/- 18% (SD) for influenza, 73% +/- 22% for hepatitis B full or partial series, 62% +/- 25% for hepatitis B full series, and 44% +/- 34% for pneumococcal vaccine. Compared with individual orders, facility-wide standing orders and chart orders were not associated with greater vaccination rates for influenza (0.4%; confidence interval, -4 to 5; and 1.27%; confidence interval, -3 to 5, respectively), but were associated with greater vaccination rates for hepatitis B full or partial series (9%; confidence interval, 3 to 15; and 11%; confidence interval, 5 to 17, respectively), hepatitis B full series (11%; confidence interval, 4 to 17; and 13%; confidence interval, 7 to 19, respectively), and pneumococcal disease (21%; confidence interval, 14 to 29; and 20%; confidence interval, 13 to 27, respectively).

LIMITATIONS

Data are cross-sectional, and vaccinations outside the center were self-reported.

CONCLUSIONS

Existing facility-wide or chart-based order programs may be effective in promoting vaccination against hepatitis B and pneumococcal disease.

Practice-proven interventions to increase vaccination rates and broaden the immunization season

The Centers for Disease Control and Prevention (CDC) recommends that most (73%) persons residing in the United States be vaccinated against influenza each year. The actual rate of influenza vaccination is substantially below target levels: about 60% of persons >or=65 years (target is 90%) and only 10% to 40% of other groups (target is 60% for younger persons who have risk factors and 60% for healthcare personnel). Vaccinating patients throughout the influenza vaccination season (from October into January and beyond)--providing access beyond the traditional "fall immunization season"--is an important step toward meeting the substantial need for influenza vaccination. Vaccination rates may also be increased by interventions that increase patient demand and access to vaccine and overcome practice-related barriers. Such interventions include vaccination-only clinics, standing orders, strong recommendations from healthcare providers, as well as reminder and recall efforts. For maximum impact on immunization rates, interventions should be combined into a multifaceted immunization program rather than used alone. Interventions that address site-specific needs, taking resources into account, should be implemented on a practice-by-practice basis. With supply of influenza vaccine now plentiful, efforts need to be focused on reducing missed vaccination opportunities and promoting vaccination beyond the traditional fall time frame to protect as many Americans as possible from serious and potentially deadly influenza infection.

Project VIVA: a multilevel community-based intervention to increase influenza vaccination rates among hard-to-reach populations in New York City

OBJECTIVES

We sought to determine whether the work of a community-based participatory research partnership increased interest in influenza vaccination among hard-to-reach individuals in urban settings.

METHODS

A partnership of researchers and community members carried out interventions for increasing acceptance of influenza vaccination in disadvantaged urban neighborhoods, focusing on hard-to-reach populations (e.g., substance abusers, immigrants, elderly, sex workers, and homeless persons) in East Harlem and the Bronx in New York City. Activities targeted the individual, community organization, and neighborhood levels and included dissemination of information, presentations at meetings, and provision of street-based and door-to-door vaccination during 2 influenza vaccine seasons. Participants were recruited via multiple modalities. Multivariable analyses were performed to compare interest in receiving vaccination pre- and postintervention.

RESULTS

There was increased interest in receiving the influenza vaccine postintervention (P<.01). Being a member of a hard-to-reach population (P=.03), having ever received an influenza vaccine (P<.01), and being in a priority group for vaccination (P<.01) were also associated with greater interest in receiving the vaccine.

CONCLUSIONS

Targeting underserved neighborhoods through a multilevel community-based participatory research intervention significantly increased interest in influenza vaccination, particularly among hard-to-reach populations. Such interventions hold promise for increasing vaccination rates annually and in pandemic situations.

Influenza vaccination of recommended adult populations, U.S., 1989-2005

OBJECTIVE

To assess influenza vaccination coverage among recommended adult populations in the United States.

METHODS

Data from the 1989 to 2005 National Health Interview Surveys (NHISs), weighted to reflect the civilian, non-institutionalized U.S. population, were analyzed to determine self-reported levels of influenza vaccination among persons aged >or=65 years, persons with high-risk conditions, health care workers (HCW), pregnant women, and persons living in households with at least one identified person at high risk of complications from influenza infection. We stratified data by race/ethnicity to identify racial/ethnic disparities.

RESULTS

Vaccination coverage levels among all recommended adult populations peaked in 2004, then declined in 2005 in association with the 2004-2005 vaccine shortage. Coverage for adults >or=65 years of age increased from 30.1% (95% confidence interval [CI]: 28.8-31.3) in 1989 to 70.0% (68.0-71.5) in 2004. In 2004, coverage was 40.7% (39.0-42.5) for all adults 50-64 years, 27.2% (24.6-29.9) for adults aged 18-49 years with high-risk conditions, 43.2% (39.9-46.6) for health care workers, 21.1% (19.1-23.4) for non-high-risk adults aged 18-64 years with a high-risk household member, and 14.4% (8.8-22.9) for pregnant women. Among each of the recommended adult sub-groups, vaccination coverage was higher for non-Hispanic whites compared to minority groups.

CONCLUSIONS

By 1997, influenza vaccination coverage had exceeded the national 2000 objective of 60% among persons aged >or=65 years, but by 2004 still remains well below the national 2010 target of 90%. Coverage levels for other groups targeted for influenza vaccination also are far short of the Healthy People 2000 and 2010 goals of 60% for persons aged 18-64 years with high-risk conditions, health care workers, and pregnant women. A concerted effort to increase provider adoption of standards for adult immunization, public awareness, and stable vaccine supplies are needed to improve influenza vaccination rates among recommended groups, and to reduce racial and ethnic disparities.

Implementation and evaluation of a nursing assessment/standing orders-based inpatient pneumococcal vaccination program

BACKGROUND

Pneumococcal vaccination is recommended for patients aged 65 years and greater; inpatient vaccination has been suggested as means to increase vaccination rates is this population. Our hospital implemented an inpatient pneumococcal vaccination program, and expanded the population of interest to include patients aged 2 to 64 years with risk factors for pneumococcal bacteremia. We studied the outcomes of this program to determine if the rate of pneumococcal vaccination opportunities and pneumococcal vaccination rate could be significantly increased through the application of an in-hospital pneumococcal vaccination program, based on standing orders and assessment by Registered Nurses, when compared to our previous method of physician assessment and written vaccination order for each patient.

METHODS

Subjects were inpatients admitted to non-intensive care units of our hospital from August to December of 2004. Cases were aged greater than 65 years, or were greater than 2 years of age with selected risk factors. Patients with previous pneumococcal vaccination with the past five years, in terminal or comfort care, those allergic to vaccine components, patients who received organ or bone marrow transplants in the year prior to the study, and those physicians barred them from the vaccination protocol were excluded. Program effectiveness was evaluated through retrospective evaluation of medical records to determine if subjects had been evaluated for vaccination eligibility, and if subjects were eligible, whether or not they had received pneumococcal vaccination.

RESULTS

Overall vaccination opportunity rate after implementation of the standing orders-based program increased form 8.6% to 59.1%, and overall vaccination rates improved form 0% to 15.4%. The study found a statistically significant difference in the rate of pneumococcal vaccination opportunities (chi(2) = 182.46, p = .00) and the pneumococcal vaccination rate (chi(2) = 56, p = .00) between the two methods of assessment and vaccination; these results are attributable to the study intervention.

CONCLUSIONS

The study program contributed to increased overall vaccination opportunity and vaccination rates, when compared to the previous method. The overall rates of vaccination attained by this program were often lower than those reported in the existing literature for other program designs; however, this may be due to an unusually high rate of vaccination refusal.

Strategies for improving influenza immunization rates among hard-to-reach populations

Whereas considerable attention has been devoted to achieving high levels of influenza immunization, the importance of this issue is magnified by concern over pandemic influenza. Most recommendations for vaccine administration address high risk groups such as the elderly and those with chronic diseases, but coverage for hard-to-reach (HTR) populations has had less attention. HTR populations include minorities but also include other primarily urban groups such as undocumented immigrants, substance users, the homeless, and homebound elderly. Obstacles to the provision of immunization to HTR populations are present at the patient, provider, and structural levels. Strategies at the individual level for increasing immunization coverage include community-based educational campaigns to improve attitudes and increase motivation for receiving vaccine; at the provider level, education of providers to encourage immunizations, improving patient-provider interactions, broadening the provider base to include additional nurses and pharmacists, and adoption of standing orders for immunization administration; and at the structural level, promoting wider availability of and access to vaccine. The planning process for an influenza pandemic should include community engagement and extension of strategies beyond traditional providers to involve community-based organizations addressing HTR populations.

Variations in influenza vaccination coverage among the high-risk population in Sweden in 2003/4 and 2004/5: a population survey

Background

In Sweden, the vaccination campaign is the individual responsibility of the counties, which results in different arrangements. The aim of this study was to find out whether influenza vaccination coverage rates (VCRs) had increased between 2003/4 and 2004/5 among population at high risk and to find out the influence of personal preferences, demographic characteristics and health care system characteristics on VCRs.

Methods

An average sample of 2500 persons was interviewed each season (2003/4 and 2004/5). The respondents were asked whether they had had an influenza vaccination, whether they suffered from chronic conditions and the reasons of non-vaccination. For every county the relevant health care system characteristics were collected via a questionnaire sent to the medical officers of communicable diseases.

Results

No difference in VCR was found between the two seasons. Personal invitations strongly increased the chance of having had a vaccination. For the elderly, the number of different health care professionals in a region involved in administering vaccines decreased this chance.

Conclusion

Sweden remained below the WHO-recommendations for population at high risk due to disease. To meet the 2010 WHO-recommendation further action may be necessary to increase vaccine uptake. Increasing the number of personal invitations and restricting the number of different administrators responsible for vaccination may be effective in increasing VCRs among the elderly.

Impact of two different models on influenza and pneumococcal vaccination in hospitalized patients

OBJECTIVE

The Centers for Disease Control (CDC) recommends trivalent influenza (TIV) and pneumococcal (PPV) vaccination for eligible hospitalized patients. We conducted a retrospective study comparing two different methods of assessment and its impact on TIV and PPV vaccination in hospitalized patients.

DESIGN

Two sequential models were compared in a community hospital for assessing patients' vaccination status and eligibility for TIV and PPV in an inpatient setting. In the first model (Model I), physicians were responsible for assessing eligibility and ordering TIV and/or PPV. In the second model (Model II), nurses were responsible for assessment and vaccination of eligible patients. Charts of hospitalized patients were randomly analyzed for completion rates of the assessment form, rate of vaccination, and documentation of the reason for not vaccinating eligible patients.

RESULTS

A total of 138 charts were analyzed for Model I and 168 charts were analyzed for Model II. A significantly higher completion rate for assessment was noted for Model II compared with Model I (79.16% versus 34.78%, P < 0.001 for TIV; 72.02% versus 33.33%, P < 0.001 for PPV). Hospital vaccination rates were not significantly different between the two models for TIV (P = 0.625) and PPV (P = 0.689). A significant percentage of patients refused PPV in Model II [8.03% versus Model I at 3.2% (P = 0.04)].

CONCLUSION

A standing order protocol for assessing hospitalized patients' vaccination status by nursing staff and allowing them to vaccinate eligible patients without depending upon a physician order significantly improved the assessment compliance rate, but not the vaccination rates. Our findings suggest that a system-based method with nursing assessing the need for vaccination and a physician ordering the vaccination would probably have a higher potential for success.

Influenza vaccination among persons with chronic respiratory diseases: coverage, related factors and time-trend, 1993-2001

BACKGROUND

Influenza vaccination has shown itself to be effective in reducing morbidity and mortality in patients with underlying chronic respiratory diseases. This study sought to: (1) estimate influenza vaccination coverage among asthma and chronic bronchitis sufferers; (2) ascertain which variables were associated with vaccination; and (3) analyse the time-trend in coverage between 1993 and 2001.

METHODS

This was a descriptive study covering the 2611 subjects included in the 1993, 1995, 1997 and 2001 Spanish National Health Surveys who reported suffering from asthma or chronic bronchitis. Vaccination coverage was calculated for each year and the influence of socio-demographic and health-related variables analysed. Using logistic regression, we assessed which of the variables had an independent effect on vaccination, and analysed the time-trend.

RESULTS

The proportions of vaccinated subjects in 1993, 1995-1997 and 2001 were 44.7%, 45.6% and 44.4%, respectively. Variables that increased the likelihood of having been vaccinated were: higher age, presence of another concomitant chronic disease, poor perception of health, non-smoker status, and being married. There was no significant variation in coverage over the study period.

CONCLUSION

Influenza vaccination coverage among Spanish asthma and/or chronic bronchitis sufferers is below desirable levels and showed no improvement over the period 1993-2001. Implementation of strategies to improve coverage is necessary.

Providers' beliefs, attitudes, and behaviors before implementing a computerized pneumococcal vaccination reminder

BACKGROUND

The emergency department (ED) has been recommended as a suitable setting for offering pneumococcal vaccination; however, implementations of ED vaccination programs remain scarce.

OBJECTIVES

To understand beliefs, attitudes, and behaviors of ED providers before implementing a computerized reminder system.

METHODS

An anonymous, five-point Likert-scale, 46-item survey was administered to emergency physicians and nurses at an academic medical center. The survey included aspects of ordering patterns, implementation strategies, barriers, and factors considered important for an ED-based vaccination initiative as well as aspects of implementing a computerized vaccine-reminder system.

RESULTS

Among 160 eligible ED providers, the survey was returned by 64 of 67 physicians (96%), and all 93 nurses (100%). The vaccine was considered to be cost effective by 71% of physicians, but only 2% recommended it to their patients. Although 98% of physicians accessed the computerized problem list before examining the patient, only 28% reviewed the patient's health-maintenance section. Physicians and nurses preferred a computerized vaccination-reminder system in 93% and 82%, respectively. Physicians' preferred implementation approach included a nurse standing order, combined with physician notification; nurses, however, favored a physician order. Factors for improving vaccination rates included improved computerized documentation, whereas increasing the number of ED staff was less important. Relevant implementation barriers for physicians were not remembering to offer vaccination, time constraints, and insufficient time to counsel patients. The ED was believed to be an appropriate setting in which to offer vaccination.

CONCLUSIONS

Emergency department staff had favorable attitudes toward an ED-based pneumococcal vaccination program; however, considerable barriers inherent to the ED setting may challenge such a program. Applying information technology may overcome some barriers and facilitate an ED-based vaccination initiative.

Compliance with influenza and pneumococcal vaccination among patients with chronic obstructive pulmonary disease consulting their medical practitioners in Catalonia, Spain

OBJECTIVES

This survey describes influenza and pneumococcal vaccination coverage among patients suffering from chronic obstructive pulmonary disease (COPD), and analyses the factors related to compliance with both vaccine recommendations.

METHODS

This is a descriptive study conducted in the primary-care setting in Catalonia, Spain. Information was drawn from patients' clinical histories and personal interviews. As the dependent variable, we took the answer (yes or no) to the questions "were you vaccinated against influenza during the last campaign?" and "have you ever been given a pneumococcal vaccine shot?". As independent variables, we analysed health status, sociodemographic and lifestyle data.

RESULTS

A total of 1783 patients were included in the study, 62.5% of whom reported having received both influenza and pneumococcal vaccines. Higher age, more frequent contact with the general practitioner and greater length of disease progression considerably increased the likelihood of having received both vaccines.

CONCLUSIONS

Compliance with influenza and pneumococcal vaccination recommendations among Catalonian COPD patients treated in a primary-care setting are better than those found among other high risk groups elsewhere. Nevertheless, different strategies should be implemented to improve compliance among younger patients and those who lead less healthy lifestyles, such as smoking or alcohol consumption.

Quality of occupational history assessments in working age adults with newly diagnosed asthma

BACKGROUND

Approximately 10 to 15% of new-onset asthma in adults is attributable to occupational exposure. The occupational history is the most important instrument in the diagnosis of occupational asthma (OA).

STUDY OBJECTIVES

To assess the quality of occupational histories obtained by health-care providers and to measure the prevalence of clinician-diagnosed OA in a population at elevated risk for OA.

SETTING

An academic US Department of Veteran Affairs medical center.

STUDY POPULATION

One hundred ninety-seven adults (age range, 18 to 55 years) with newly diagnosed asthma who had completed pulmonary function testing (PFT) and a structured respiratory health questionnaire.

MEASUREMENTS

We conducted a structured retrospective comparison of occupational respiratory health history documented by clinicians with data documented by patients on a structured questionnaire. We analyzed PFT results to assess physiologic impairment. We also conducted a structured examination of the actions taken by health-care providers based on their occupational history assessments.

RESULTS

Patient self-reports of respiratory exposures and symptoms were common. A job title was documented by one or more clinicians in 75% of patient medical records. Additional occupational history data were charted much less frequently. A diagnosis of OA was made in only 2% of patients. Clinical action to address OA was documented for only one patient.

CONCLUSIONS

Clinicians who manage adults with newly diagnosed asthma take incomplete occupational histories. We detected discordance between the occupational exposure histories documented by patients and those charted by clinicians. OA may go unrecognized and possibly undermanaged by clinicians.

Influenza Season Triggers Pneumococcal Vaccination

OBJECTIVES

To investigate the frequency with which influenza and pneumococcal vaccines are administered alone and together.

DESIGN

Retrospective review.

SETTING

Marshall University internal medicine practice, Huntington, West Virginia.

PARTICIPANTS

All patients aged 65 and older seen in the practice from 1999 through 2005 who received pneumococcal or influenza vaccine.

MEASUREMENTS

Billing records were reviewed for administration of pneumococcal and influenza vaccines to Medicare beneficiaries, and rates of administration of these vaccines given alone and together were calculated.

RESULTS

Nine hundred sixty-nine doses of pneumococcal vaccine were administered. Of these, 796 (82%) were administered during the fall and winter. Three hundred fifty-six (45%) pneumococcal vaccinees received it together with influenza vaccine. During 2001 and 2005, when influenza vaccine supply was limited, the rate of pneumococcal vaccine administered together with influenza vaccine declined sharply. Nonetheless, the rate of pneumococcal vaccination remained relatively stable because of an increase in the rate of vaccine administered alone.

CONCLUSION

Four-fifths of pneumococcal vaccine was administered in the fall and winter, and approximately half was given together with influenza vaccine. When influenza vaccine was in limited supply, physicians continued to vaccinate with pneumococcal vaccine alone. These findings suggest that the imminent influenza season provides the trigger for physicians to prescribe pneumococcal vaccine. Physicians should be reminded that pneumococcal vaccine can be administered any time of year.

Influenza work on the regional level in Sweden: an integrated program for vaccination of risk groups, surveillance and pandemic planning which focuses on the role of the health care worker

The aim of the study was to increase the vaccination rates of influenza among the risk groups in Region Västra Götaland, Sweden. The main interventions performed were education of doctors and nurses, information on the Internet and advice on administrative routines and organisation for the task. There was no campaign towards the risk group and no reimbursement. The vaccination rate increased from 33.6 to 54.6% in the Göteborg area between 1999 and 2004 and from 44.1 to 51.9% in the whole region. Vaccination rates increased with age and chronic disease in the elderly population, among person's 20-64 years of age with chronic disease only 23.8-34.0% were vaccinated. In order to increase the vaccination coverage in persons with chronic disease the program intensified the education of hospital staff. It was then evident that the awareness and knowledge about influenza and vaccination was limited among hospital doctors. The study demonstrates the key role of health care workers in a vaccination program and points at the importance of preparing the personnel for a pandemic situation. Co-ordination of the vaccination program with the surveillance and pandemic planning are effective means of strengthening the preventive work against influenza.

Panning for gold: an evidence-based tool for assessment of performance indicators in primary health care

It is important that debate occurs between theorists, policy makers, clinicians and service end-users to develop agreement over suitable and appropriate indicators for primary health care. A formal accounting of the relative strengths and weaknesses of any proposed indicator will enable sector commentators from a variety of viewpoints to discuss the relative merits of individual indicators, to understand the political and pragmatic reasons for their inclusion in any set of indicators and to trace the likely organisational impact of any given indicator. This paper details the development of an indicator appraisal tool that combines the assessment of scientific evidence with contextual considerations from the perspective of both the policy environment and the primary health care sector. The use of the tool is discussed in the context of the proposed national implementation of a set of performance indicators in New Zealand.

Lessons learned from inpatient vaccination in Michigan

This study was a retrospective, preintervention and postintervention evaluation of influenza and pneumococcal vaccination among hospitalized patients eligible for vaccination. The authors abstracted 1476 randomly sampled patient charts to compare vaccination before (2002) or after (2003) implementation of vaccination policies in 4 Michigan hospitals. In addition, they assessed completeness of vaccine assessment forms, evaluated reasons for nonvaccination, and conducted interviews with hospital staff. Vaccination increased at 3 of 4 hospitals after implementation of vaccination policies, yet rates remained low (<10% overall; range, 3.4%-12.4%). Vaccine assessment forms were found in most of the charts in 2003, but almost a third were incomplete. Challenges to implementing inpatient vaccination included support and training of hospital staff, interpretation of vaccination recommendations, lack of systematic prompts for vaccinations, and cost reimbursement. These findings underscore the need for continuous quality improvement and process monitoring to determine strategies for overcoming challenges to inpatient vaccination.
