Patient reminder and patient recall systems to improve immunization rates

An Australian audit of vaccination status in children and adolescents with inflammatory bowel disease

BACKGROUND

Children and adolescents with inflammatory bowel disease (IBD) are at increased risk of vaccine preventable diseases (VPD). This includes invasive pneumococcal disease and influenza. The primary aim of this study was to describe compliance with current Australian guidelines for vaccination of children and adolescents diagnosed with IBD. A secondary aim was to review the serological screening for VPD.

METHODS

A random sample of patients (0-18 years at diagnosis), were selected from the Victoria Australia state based Pediatric Inflammatory Bowel Disease Register. A multi-faceted retrospective review of immunization status was undertaken, with hospital records audited, a telephone interview survey conducted with consenting parents and the vaccination history was checked against the primary care physician and Australian Childhood Immunization Register (ACIR) records. The routine primary childhood vaccinations and administration of the recommended additional influenza and pneumococcal vaccines was clarified.

RESULTS

This 2007 audit reviewed the immunization status of 101 individuals on the Victorian Pediatric IBD database. Median age at diagnosis was 12.1 years, 50% were on active immunosuppressive therapy. 90% (38/42) [95% confidence intervals (CI) 77%; 97%] with complete immunization information were up-to-date with routine primary immunizations. Only 5% (5/101) [95% CI 2%; 11%] received a recommended pneumococcal vaccine booster and 10% (10/101) [95% CI 5%; 17%] had evidence of having ever received a seasonal influenza vaccine. Those living in rural Victoria (p = 0.005) and younger at the age of diagnosis (p = 0.002) were more likely to have ever received an influenza vaccine Serological testing, reviewing historical protection from VPD, identified 18% (17/94) with evidence of at least one serology sample.

CONCLUSION

This study highlights poor compliance in IBD patients for additional recommended vaccines. A multi-faceted approach is required to maximize protection from VPD in this vulnerable special risk population.

Disparity in childhood immunizations

BACKGROUND

Incomplete immunization coverage is common in low-income families and Aboriginal children in Canada.

OBJECTIVE

To determine whether child immunization coverage rates at two years of age were lower in low-income neighbourhoods of Saskatoon, Saskatchewan.

METHODS

Parents who were and were not behind in child immunization coverage were contacted to determine differences in knowledge, beliefs and opinions on barriers and solutions. A multivariate regression model was designed to determine whether Aboriginal cultural status was associated with being behind in childhood immunizations after controlling for low-income status.

RESULTS

Reviewing the past five years in Saskatoon, the six low-income neighbourhoods had complete child immunization coverage rates of 43.7% (95% CI 41.2 to 45.9) for measles-mumps-rubella, and 42.6% (95% CI 40.1 to 45.1) for diphtheria, pertussis, tetanus, polio and Haemophilus influenzae type B. The five affluent neighbourhoods had 90.6% (95% CI 88.9 to 92.3) immunization coverage rates for measles-mumps-rubella, and 78.6% (95% CI 76.2 to 81.0) for diphtheria, pertussis, tetanus, polio and H influenzae type B. Parents who were behind in immunization coverage for their children were more likely to be single, of Aboriginal or other (non-Caucasian or non-Aboriginal) cultural status, have lower family income and have significant differences in reported beliefs, barriers and potential solutions. In the final regression model, Aboriginal cultural status was no longer associated with lower immunization status.

INTERPRETATION

Child immunization coverage rates in Saskatoon's six low-income neighbourhoods were approximately one-half the rate of the affluent neighbourhoods. The covariates with the strongest independent association with complete childhood immunization status were low income and other cultural status. Aboriginal cultural status was not associated with low child immunization rates after controlling for income status.

Interventions for improving coverage of child immunization in low- and middle-income countries

BACKGROUND

Immunization coverage remains low, particularly in low- and middle-income countries (LMIC), despite its proven effectiveness in reducing the burden of childhood infectious diseases. A Cochrane review has shown that patient reminder recall is effective in improving coverage of immunization but technologies to support this strategy are lacking in LMIC.

OBJECTIVES

To evaluate the effectiveness of intervention strategies to boost and sustain high childhood immunization coverage in LMIC.

SEARCH STRATEGY

We searched the following databases for primary studies: Cochrane Central Register of Controlled Trials (CENTRAL) 2010, Issue 1, part of The Cochrane Library. www.thecochranelibrary.com, including the Cochrane Effective Practice and Organisation of Care (EPOC) Group Specialised Register (searched 8 July 2010); MEDLINE, Ovid (1948 to March Week 3 2011) (searched 30 March 2011); EMBASE, Ovid (1980 to 2010 Week 26) (searched 8 July 2010); CINAHL, EBSCO (1981 to present ) (searched 8 July 2010); LILACS, VHL (1982 to present) (searched 8 July 2010); Sociological Abstracts, CSA Illumnia (1952 to current) (searched 8 July 2010). Reference lists of all papers and relevant reviews were identified and searched for additional studies.

SELECTION CRITERIA

Included studies were randomized controlled trials (RCTs), non-randomized controlled trials (NRCTs), and interrupted-time-series (ITS) studies. Study participants were children aged 0 to 4 years, caregivers, and health providers. Interventions included patient and community-oriented interventions, provider-oriented interventions, health system interventions, multi-faceted (any combination of the above categories of interventions), and any other single or multifaceted intervention intended to improve childhood immunisation coverage The primary outcome was the proportion of the target population fully immunized with recommended vaccines by age.

DATA COLLECTION AND ANALYSIS

Two authors independently screened full articles of selected studies, extracted data, and assessed study quality.

MAIN RESULTS

Six studies were included in the review; four were at high risk of bias. There was low quality evidence that: facility based health education may improve the uptake of combined vaccine against diphtheria, pertussis, and tetanus (DPT3) coverage (risk ratio (RR) 1.18; 95% CI 1.05 to 1.33); and also that a combination of facility based health education and redesigned immunization cards may improve DPT3 coverage (RR 1.36; 95% CI 1.22 to 1.51). There was also moderate quality evidence that: evidence-based discussions probably improve DPT3 coverage (RR 2.17; 95% CI 1.80 to 2.61), and that information campaigns probably increase uptake of at least a dose of a vaccine (RR 1.43; 95% CI 1.01 to 2.02).

AUTHORS' CONCLUSIONS

Home visits and health education may improve immunization coverage but the quality of evidence is low.

A brief review of vaccination coverage in immunization registries

Immunization registries are effective electronic tools for assessing vaccination coverage, but are only as good as the information reported to them. This review summarizes studies through August 2010 on vaccination coverage in registries and identifies key characteristics of successful registries. Based on the current state of registries, paper-based charts combined with electronic registry reporting provide the most cohesive picture of coverage. To ultimately supplant paper charts, registries must exhibit increased coverage and participation.

Preparing for influenza after 2009 H1N1: special considerations for pregnant women and newborns

Pregnant women and their newborn infants are at increased risk for influenza-associated complications, based on data from seasonal influenza and influenza pandemics. The Centers for Disease Control and Prevention (CDC) developed public health recommendations for these populations in response to the 2009 H1N1 pandemic. A review of these recommendations and information that was collected during the pandemic is needed to prepare for future influenza seasons and pandemics. The CDC convened a meeting entitled "Pandemic Influenza Revisited: Special Considerations for Pregnant Women and Newborns" on August 12-13, 2010, to gain input from experts and key partners on 4 main topics: antiviral prophylaxis and therapy, vaccine use, intrapartum/newborn (including infection control) issues, and nonpharmaceutical interventions and health care planning. Challenges to communicating recommendations regarding influenza to pregnant women and their health care providers were also discussed. After careful consideration of the available information and individual expert input, the CDC updated its recommendations for these populations for future influenza seasons and pandemics.

Contact and communication with healthcare providers regarding influenza vaccination during the 2009-2010 H1N1 pandemic

OBJECTIVE

The existence of two vaccines-seasonal and pandemic-created the potential for confusion and misinformation among consumers during the 2009-2010 vaccination season. We measured the frequency and nature of influenza vaccination communication between healthcare providers and adults for both seasonal and 2009 influenza A(H1N1) vaccination and quantified its association with uptake of the two vaccines.

METHODS

We analyzed data from 4040 U.S. adult members of a nationally representative online panel surveyed between March 4th and March 24th, 2010. We estimated prevalence rates and adjusted associations between vaccine uptake and vaccination-related communication between patients and healthcare providers using bivariate probit models.

RESULTS

64.1% (95%-CI: 61.5%-66.6%) of adults did not receive any provider-issued influenza vaccination recommendation. Adults who received a provider-issued vaccination recommendation were 14.1 (95%-CI: -2.4 to 30.6) to 32.1 (95%-CI: 24.3-39.8) percentage points more likely to be vaccinated for influenza than adults without a provider recommendation, after adjusting for other characteristics associated with vaccination.

CONCLUSIONS

Influenza vaccination communication between healthcare providers and adults was relatively uncommon during the 2009-2010 pandemic. Increased communication could significantly enhance influenza vaccination rates.

Pay-for-performance incentives for preventive care: views of family physicians before and after participation in a reminder and recall project (P-PROMPT)

OBJECTIVE

The Provider and Patient Reminders in Ontario: Multi-Strategy Prevention Tools (P-PROMPT) project was designed to increase the rates of delivery of 4 targeted preventive care services to eligible patients in primary care network and family health network practices eligible for pay-for-performance incentives.

DESIGN

Self-administered fax-back surveys completed before and after participation in the P-PROMPT project.

SETTING

Southwestern Ontario.

PARTICIPANTS

A total of 246 physicians from 24 primary care network or family health network practices across 110 different sites.

INTERVENTIONS

The P-PROMPT project provided several tools and services, including physician and patient reminders, office management tools, and administrative database integration.

MAIN OUTCOME MEASURES

Physicians' views about the delivery of preventive health services and pay-for-performance incentives before and after participation in the P-PROMPT project.

RESULTS

The preintervention survey was completed by 86.2% (212 of 246) of physicians and the postintervention survey was completed by 53.3% (131 of 246) of physicians; 46.7% (114 of 246) of the physicians completed both surveys. Overall, 80.5% of physicians indicated that the P-PROMPT project was useful (scores of 5 or higher on a 7-point Likert scale). Patient reminder letters (89.1%), physician approval lists of eligible patients (75.6%), administrative assistance with management fees (79.8%), and annual bonus calculations (75.2%) were rated as the most useful features of the program. Compared with the preintervention survey, there were statistically significant increases in the mean agreement scores that the established target levels and bonuses provided appropriate financial incentive to substantially increase the uptake of mammography (P=.012) and Papanicolaou tests (P=.003) but not to increase uptake of annual influenza vaccination or childhood immunizations. There were statistically significant changes in the mean ratings of relying on an opportunistic approach (P<.001), increased agreement about the effectiveness of the current approach to delivery of preventive care (P<.001), and increased use of preventive management fees to recall patients (P<.001).

CONCLUSION

The preventive care management program and P-PROMPT were viewed favourably by most respondents and were perceived to be useful in improving delivery of preventive health care services.

Vaccination coverage and timeliness in three South African areas: a prospective study

BACKGROUND

Timely vaccination is important to induce adequate protective immunity. We measured vaccination timeliness and vaccination coverage in three geographical areas in South Africa.

METHODS

This study used vaccination information from a community-based cluster-randomized trial promoting exclusive breastfeeding in three South African sites (Paarl in the Western Cape Province, and Umlazi and Rietvlei in KwaZulu-Natal) between 2006 and 2008. Five interview visits were carried out between birth and up to 2 years of age (median follow-up time 18 months), and 1137 children were included in the analysis. We used Kaplan-Meier time-to-event analysis to describe vaccination coverage and timeliness in line with the Expanded Program on Immunization for the first eight vaccines. This included Bacillus Calmette-Guérin (BCG), four oral polio vaccines and 3 doses of the pentavalent vaccine which protects against diphtheria, pertussis, tetanus, hepatitis B and Haemophilus influenzae type B.

RESULTS

The proportion receiving all these eight recommended vaccines were 94% in Paarl (95% confidence interval [CI] 91-96), 62% in Rietvlei (95%CI 54-68) and 88% in Umlazi (95%CI 84-91). Slightly fewer children received all vaccines within the recommended time periods. The situation was worst for the last pentavalent- and oral polio vaccines. The hazard ratio for incomplete vaccination was 7.2 (95%CI 4.7-11) for Rietvlei compared to Paarl.

CONCLUSIONS

There were large differences between the different South African sites in terms of vaccination coverage and timeliness, with the poorer areas of Rietvlei performing worse than the better-off areas in Paarl. The vaccination coverage was lower for the vaccines given at an older age. There is a need for continued efforts to improve vaccination coverage and timeliness, in particular in rural areas.

Consumer-oriented interventions for evidence-based prescribing and medicines use: an overview of systematic reviews

BACKGROUND

Numerous systematic reviews exist on interventions to improve consumers' medicines use, but this research is distributed across diseases, populations and settings. The scope and focus of reviews on consumers' medicines use also varies widely. Such differences create challenges for decision makers seeking review-level evidence to inform decisions about medicines use.

OBJECTIVES

To synthesise the evidence from systematic reviews on the effects of interventions which target healthcare consumers to promote evidence-based prescribing for, and medicines use, by consumers. We sought evidence on the effects on health and other outcomes for healthcare consumers, professionals and services.

METHODS

We included systematic reviews published on the Cochrane Database of Systematic Reviews and the Database of Abstracts of Reviews of Effects. We identified relevant reviews by handsearching both databases from start date to Issue 3 2008. We screened and ranked reviews based on relevance to consumers' medicines use, using criteria developed for this overview. Standardised forms were used to extract data, and reviews were assessed for methodological quality using the AMSTAR instrument. We used standardised language to summarise results within and across reviews; and a further synthesis step was used to give bottom-line statements about intervention effectiveness. Two review authors selected reviews, extracted and analysed data. We used a taxonomy of interventions to categorise reviews.

MAIN RESULTS

We included 37 reviews (18 Cochrane, 19 non-Cochrane), of varied methodological quality.Reviews assessed interventions with diverse aims including support for behaviour change, risk minimisation, skills acquisition and information provision. No reviews aimed to promote systems-level consumer participation in medicines-related activities. Medicines adherence was the most commonly reported outcome, but others such as clinical (health and wellbeing), service use and knowledge outcomes were also reported. Reviews rarely reported adverse events or harms, and the evidence was sparse for several populations, including children and young people, carers, and people with multimorbidity.Promising interventions to improve adherence and other key medicines use outcomes (eg adverse events, knowledge) included self-monitoring and self-management, simplified dosing and interventions directly involving pharmacists. Other strategies showed promise in relation to adherence but their effects were less consistent. These included reminders; education combined with self-management skills training, counselling or support; financial incentives; and lay health worker interventions.No interventions were effective to improve all medicines use outcomes across all diseases, populations or settings. For some interventions, such as information or education provided alone, the evidence suggests ineffectiveness; for many others there is insufficient evidence to determine effects on medicines use outcomes.

AUTHORS' CONCLUSIONS

Systematically assembling the evidence across reviews allows identification of effective or promising interventions to improve consumers' medicines use, as well as those for which the evidence indicates ineffectiveness or uncertainty.Decision makers faced with implementing interventions to improve consumers' medicines use can use this overview to inform these decisions and also to consider the range of interventions available; while researchers and funders can use this overview to determine where research is needed. However, the limitations of the literature relating to the lack of evidence for important outcomes and specific populations, such as people with multimorbidity, should also be considered.

Correlates of receiving recommended adolescent vaccines among adolescent females in North Carolina

BACKGROUND

Immunization is a successful and cost-effective method for preventing disease, yet many adolescents do not receive recommended vaccines. We assessed correlates of uptake of three vaccines (tetanus booster, meningococcal, and human papillomavirus [HPV] vaccines) recommended for adolescent females. Methods. We examined cross-sectional data from 647 parents of 11-20 year-old females from North Carolina who completed the Carolina HPV Immunization Measurement and Evaluation (CHIME) Project follow-up survey in late 2008. Analyses used ordinal and binary logistic regression.

RESULTS

Only 17% of parents indicated their daughters had received all three vaccines. Eighty-seven percent of parents indicated their daughters had received tetanus booster vaccine, 36% reported vaccination against meningococcal disease, and 36% reported HPV vaccine initiation. Daughters aged 13-15 years (OR = 1.70, 95% CI: 1.09-2.64) or 16-20 years (OR = 2.28, 95% CI: 1.51-3.44) had received a greater number of these vaccines compared to daughters aged 11-12 years. Daughters who had preventive care visits in the last year (OR = 4.81, 95% CI: 3.14-7.34) or whose parents had at least some college education (OR = 1.90, 95% CI: 1.29-2.80) had also received a greater number of these vaccines.

CONCLUSIONS

Few daughters, particularly 11-12 years olds, had received all three vaccines recommended for adolescent females. Ensuring annual preventive care visits and increasing concomitant administration of adolescent vaccines may help increase vaccine coverage.

Influenza vaccination coverage in the 2004/05, 2005/06, and 2006/07 seasons: a secondary data analysis based on billing data of the German associations of statutory health insurance physicians

BACKGROUND

The German Standing Committee on Vaccination recommends annual vaccination for persons in high-risk groups in order to lower the disease burden associated with seasonal influenza. The stated target is 75% vaccination coverage of people over age 60 by the year 2010. We present statistics based on billing data of the German associations of statutory health insurance physicians regarding vaccination coverage for influenza in the three seasons from 2004/05 to 2006/07.

METHODS

We analyzed anonymous data from 14 of the 17 associations of statutory health insurance physicians in Germany. The study population consisted of all persons covered by statutory health insurance in the geographical areas under study (61.5 million persons, or 86% of the total population of these areas). Vaccination coverage was calculated as the number of vaccinated persons divided by the number of persons covered by statutory health insurance.

RESULTS

The influenza vaccination coverage of the overall study population was 19% in 2004/05, 22% in 2005/06, and 21% in 2006/07. The coverage of persons over age 60 was 45% in 2004/05, 50% in 2005/06, and 49% in 2006/07 and was higher in areas that were formerly part of East Germany than in the rest of the country. More than a third of all vaccinated persons were vaccinated in all three seasons, as were almost half of the vaccinated persons over age 60.

CONCLUSION

There was no secular increase in influenza vaccination coverage over the period 2005/06 to 2006/07. The stated target of 75% vaccination coverage for persons over age 60 by the year 2010 would thus seem to represent a major challenge for all persons involved. The analysis of data of the associations of statutory health insurance physicians enables continuous monitoring of influenza vaccination coverage.

Adoption of health promotion practices in a cohort of U.S. physician organizations

BACKGROUND

Physician organizations such as medical groups and independent practice associations can play a vital role in health promotion through the adoption of effective health promotion practices such as health risk assessments, patient reminder systems, and health promotion education programs.

PURPOSE

To examine organizational changes in a cohort of physician organizations and changing health promotion practices.

METHODS

Data for a cohort of 369 physician organizations in the U.S. with 20 or more physicians were collected between September 2000 and September 2001 and subsequently from March 2006 to March 2007. Paired-sample t tests were used to identify changes in physician organization characteristics and the use of nine health promotion practices between 2000-2001 and 2006-2007.

RESULTS

Compared to 2000-2001, the cohort of physician organizations in 2006-2007 was larger, more likely to be owned by physicians; less likely to be owned by a hospital, health system, or HMO; more profitable; and more likely to use electronic information technology. Between 2000-2001 and 2006-2007, physician organizations increased the use of health risk appraisals to contact high-risk patients and increased the use of reminders for eye exams for diabetic patients. During the same time period, physician organizations decreased the use of nutrition and weight-loss health promotion programs.

CONCLUSIONS

The adding and dropping of programs among physician organizations is due to many factors, including changing regulatory environments, market conditions, populations, and new health promotion technologies. In the coming years, incentives and regulatory policy should encourage the adoption of effective health promotion practices by physician organizations.

Improving influenza vaccination rates by targeting individuals not seeking early seasonal vaccination

BACKGROUND

Influenza morbidity and mortality remain high in the United States although vaccination clearly improves health outcomes and reduces health expenditures. This study was designed to assess the effectiveness of mail and telephone reminder strategies on improving existing clinic influenza vaccination rates among those not seeking early seasonal vaccination.

METHODS

In mid-November, we randomized 1371 patients at a hypertension clinic into 1 of 2 intervention groups, a mail reminder group (letter plus the Centers for Disease Control [CDC] Influenza Vaccine Information Statement) or a phone reminder group (same information via a personal phone call), or a control group. The following spring, records were reviewed for vaccination documentation. Patients without documentation were contacted by phone to identify whether vaccination for the current season had been obtained.

RESULTS

The final analysis included 884 patients (62% women, mean age 57.2 years old): 325 in the mail reminder group, 246 in the phone reminder group, and 313 represented the control group. Overall, 388 of these patients (44%) were vaccinated. Vaccination rates were significantly higher in the intervention groups, 46% for the mail reminder group (age and sex adjusted odds ratio [OR], 1.8, 95% confidence interval [CI], 1.3-2.5; P=.001) and 56% for the phone reminder group (OR, 2.8; 95% CI, 1.9-4.0; P<.0001), compared to 33% in the control group. Both interventions increased vaccination rates in all age/sex groups.

CONCLUSION

In contrast to earlier studies, this intervention occurred later in the influenza vaccination period excluding those who seek early vaccination and allowing interventions to target those less likely to receive vaccination. Compared to previous studies demonstrating only trivial or modest benefits, both mail and phone reminders effectively increased clinic vaccination rates in our group of patients.

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.

Seasonal influenza vaccination campaigns for health care personnel: systematic review

BACKGROUND

In Canada, vaccination coverage for seasonal influenza among health care personnel remains below 50%. The objective of this review was to determine which seasonal influenza vaccination campaign or campaign components in health care settings were significantly associated with increases in influenza vaccination among staff.

METHODS

We identified articles in eight electronic databases and included randomized controlled trials, controlled before-and-after studies and studies with interrupted time series designs in our review. Two reviewers independently abstracted the data and assessed the risk of biases. We calculated risk ratios and 95% confidence intervals for randomized controlled trials and controlled before-and-after studies and described interrupted time series studies.

RESULTS

We identified 99 studies evaluating influenza vaccination campaigns for health care workers, but only 12 of the studies were eligible for review. In nonhospital health care settings, including long-term care facilities, campaigns with a greater variety of components (including education or promotion, better access to vaccines, legislation or regulation and/or role models) were associated with higher risk ratios (i.e, favouring the intervention group). Within hospital settings, the results reported for various types of campaigns were mixed. Many of the criteria for assessing risk of bias were not reported.

INTERPRETATION

Campaigns involving only education or promotion resulted in minimal changes in vaccination rates. Further studies are needed to determine the appropriate components and combinations of components in influenza vaccination campaigns for health care personnel.

Burden of influenza-related hospitalizations among children with sickle cell disease

OBJECTIVE

Children with sickle cell disease (SCD) are considered to be at high risk for complications from influenza infection despite minimal published data that characterize the burden of influenza in this population. Our objectives were to (1) estimate the rate of influenza-related hospitalizations (IRHs) among children with SCD, (2) compare this rate with rates of children with cystic fibrosis (CF) and children with neither SCD nor CF, and (3) explore mechanisms that underlie these potentially preventable hospitalizations.

METHODS

We analyzed hospitalizations from 4 states (California, Florida, Maryland, and New York) across 2 influenza seasons (2003-2004 and 2004-2005) from the Healthcare Cost and Utilization Project State Inpatient Databases. We included hospitalizations with a discharge diagnosis code for influenza in a child <18 years of age. We used census data and disease prevalence estimates to calculate denominators and compare rates of IRH among children with SCD, CF, and neither disease.

RESULTS

There were 7896 pediatric IRHs during the 2 influenza seasons. Of these, 159 (2.0%) included a co-occurring diagnosis of SCD. Annual rates of IRHs were 112 and 2.0 per 10 000 children with and without SCD, respectively, across both seasons. Children with SCD were hospitalized with influenza at 56 times (95% confidence interval: 48-65) the rate of children without SCD. Children with SCD had approximately double the risk of IRH compared with children with CF (risk ratio: 2.1 [95% confidence interval: 1.5-2.9]). IRHs among children with SCD were not longer, more costly, or more severe than IRHs among children without SCD; they were also rarely nosocomial and co-occurred with a diagnosis of asthma in 14% of cases.

CONCLUSIONS

IRHs are substantially more common among children with SCD than among those without the disease, which supports the potential importance of vigorous influenza vaccination efforts that target children with SCD.

Integrating clinical, community, and policy perspectives on human papillomavirus vaccination

Infection with genital human papillomavirus (HPV) may cause anogenital cancers, oropharyngeal cancers, anogenital warts, and respiratory papillomas. Two prophylactic vaccines (a bivalent and a quadrivalent vaccine) are now licensed and currently in use in a number of countries. Both vaccines prevent infection with HPV-16 and HPV-18, which together cause approximately 70% of cervical cancers, and clinical trials have demonstrated 90%-100% efficacy in preventing precancerous cervical lesions attributable to HPV-16 and HPV-18. One vaccine also prevents HPV-6 and HPV-11, which cause 90% of genital warts. A growing literature describes psychosocial, interpersonal, organizational, and societal factors that influence HPV vaccination acceptability. This review summarizes the current literature and presents an integrated perspective, taking into account these diverse influences. The resulting integrated framework can be used as a heuristic tool for organizing factors at multiple levels to guide intervention development and future research.

Immunization programs for infants, children, adolescents, and adults: clinical practice guidelines by the Infectious Diseases Society of America

Evidence-based guidelines for immunization of infants, children, adolescents, and adults have been prepared by an Expert Panel of the Infectious Diseases Society of America (IDSA). These updated guidelines replace the previous immunization guidelines published in 2002. These guidelines are prepared for health care professionals who care for either immunocompetent or immunocompromised people of all ages. Since 2002, the capacity to prevent more infectious diseases has increased markedly for several reasons: new vaccines have been licensed (human papillomavirus vaccine; live, attenuated influenza vaccine; meningococcal conjugate vaccine; rotavirus vaccine; tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis [Tdap] vaccine; and zoster vaccine), new combination vaccines have become available (measles, mumps, rubella and varicella vaccine; tetanus, diphtheria, and pertussis and inactivated polio vaccine; and tetanus, diphtheria, and pertussis and inactivated polio/Haemophilus influenzae type b vaccine), hepatitis A vaccines are now recommended universally for young children, influenza vaccines are recommended annually for all children aged 6 months through 18 years and for adults aged > or = 50 years, and a second dose of varicella vaccine has been added to the routine childhood and adolescent immunization schedule. Many of these changes have resulted in expansion of the adolescent and adult immunization schedules. In addition, increased emphasis has been placed on removing barriers to immunization, eliminating racial/ethnic disparities, addressing vaccine safety issues, financing recommended vaccines, and immunizing specific groups, including health care providers, immunocompromised people, pregnant women, international travelers, and internationally adopted children. This document includes 46 standards that, if followed, should lead to optimal disease prevention through vaccination in multiple population groups while maintaining high levels of safety.

Availability of human papillomavirus vaccine at medical practices in an area with elevated rates of cervical cancer

PURPOSE

To assess availability of human papillomavirus (HPV) vaccine at medical practices in an area with elevated cervical cancer rates.

METHODS

During July-November 2007, we conducted a telephone survey of staff at medical practices providing outpatient care to 9- to 26-year-old females in four North Carolina counties with elevated cervical cancer rates. We assessed availability of HPV vaccine and concerns about its provision.

RESULTS

Staff from 71 of 96 eligible practices completed a full interview. Overall, 62% of these practices had HPV vaccine available to patients (family practice, 74%; pediatrics, 75%; obstetrics-gynecology, 64%; internal medicine, 15%). In multivariate analysis, practice characteristics that independently predicted a lower likelihood of carrying HPV vaccine were having at least 50% African-American patient population (odds ratio [OR] 0.19, 95% confidence interval [CI] 0.06-0.63) and providing only privately purchased (and no state-supplied) vaccines (OR 0.19, 95% CI 0.06-0.63). HPV vaccine nonproviders were significantly more likely than HPV vaccine providers to report "large" concerns about the up-front costs of purchasing HPV vaccine (52% vs. 27%, p < .05) and late reimbursement (33% vs. 14%, p < .05).

CONCLUSIONS

Approximately 1 year after its introduction, HPV vaccine was available at three-quarters of family practice and pediatrics practices, two-thirds of obstetrics-gynecology practices, and few internal medicine practices in an area with elevated cervical cancer rates. Practices' concerns about cost and reimbursement have implications for accessibility of HPV vaccine to those who need it most.

Effects of an ongoing epidemic on the annual influenza vaccination rate and vaccination timing among the Medicare elderly: 2000-2005

OBJECTIVES

We assessed short-term responsiveness of influenza vaccine demand to variation in timing and severity of influenza epidemics since 2000. We tested the hypothesis that weekly influenza epidemic activity is associated with annual and daily influenza vaccine receipt.

METHODS

We conducted cross-sectional survival analyses from the 2000-2001 to 2004-2005 influenza seasons among community-dwelling elderly using the Medicare Current Beneficiary Survey (unweighted n = 2280-2822 per season; weighted n = 7.7-9.7 million per season). The outcome variable was daily vaccine receipt. Covariates included the biweekly changes of epidemic and vaccine supply at 9 census-region levels.

RESULTS

In all 5 seasons, biweekly epidemic change was positively associated with overall annual vaccination (e.g., 2.7% increase in 2003-2004 season) as well as earlier vaccination timing (P < .01). For example, unvaccinated individuals were 5%-29% more likely to receive vaccination after a 100% biweekly epidemic increase.

CONCLUSIONS

Accounting for short-term epidemic responsiveness in predicting demand for influenza vaccination may improve vaccine distribution and the annual vaccination rate, and might assist pandemic preparedness planning.

Vaccine adherence in adolescents

Although a number of routine and catch-up vaccinations are currently recommended for adolescents, coverage rates of these vaccines are currently suboptimal. Routine recommended immunizations for this cohort include vaccines for influenza, human papillomavirus, and meningococcal disease, as well as a booster for tetanus, diphtheria, and acellular pertussis. Adolescence is also a critical period for administration of catch-up vaccines for those not fully immunized during childhood. Adolescents who do not seek appropriate preventive healthcare are at risk for significant morbidity and possible mortality. Increasing adolescent adherence to recommended vaccine schedules presents a challenge and opportunity for pediatricians and public health advocates. This article outlines barriers to vaccine compliance among adolescents and discusses strategies to increase vaccine uptake.

Disparities in influenza vaccination coverage rates by target group in five European countries: trends over seven consecutive seasons

BACKGROUND

The primary objective of this study was to measure influenza vaccination coverage rates in the general population, including children, and in high-risk groups of five European countries during the season 2007/2008. An additional aim was to analyze coverage trends over seven consecutive seasons and to gain an understanding of the primary drivers and barriers to immunization.

METHODS

Community-based telephone and mail surveys have been conducted in the UK, Germany, Italy, France, and Spain, yearly, since 2001/2002. Approximately 2,000 individuals per country and season were interviewed who were considered to be representative of the adult population aged 14 years and older. Data on the vaccination status of children were obtained by proxy interviews. The questionnaire used was essentially the same for all seven seasons. Five target groups were identified for the study: (1) persons aged > or = 65 years; (2) elderly suffering from a chronic illness; (3) patients suffering from a chronic illness; (4) persons working in the health care sector; (5) children.

RESULTS

In the season 2007/2008, vaccination coverage rates in the general population remained stable in Germany. Compared to the coverage rates of the previous season, increases of 3.7%, 2.0%, and 1.8% were observed for the UK, Spain, and France, respectively, while a decrease of -1.5% was observed for Italy. Across all five countries, vaccination rates in the predefined target groups decreased to some extent (elderly) or increased slightly (chronically ill and health care workers). Vaccination rates among children varied strongly between countries and ranged from 6.1% in UK to 19.3% in Germany. The most powerful motivation for getting vaccinated in all countries was advice from a family doctor (58.6%) and the perception of influenza as a serious illness (51.9%). The major reasons why individuals did not become vaccinated were (1) the feeling of not being likely to catch influenza (39.5%) and (2) never having considered the option of being vaccinated (35.8%).

CONCLUSIONS

The change in general influenza vaccination coverage in the 2007/2008 season compared to the previous season was small, but decreases were seen in some target groups. The underlying motivations for and against vaccination did not substantially change. An effort to activate those driving forces that would encourage vaccination as well as dealing with barriers that tend to prevent it may help enhance coverage rates in Europe in the future.

Modelling innovative interventions for optimising healthy lifestyle promotion in primary health care: "prescribe Vida Saludable" phase I research protocol

BACKGROUND

The adoption of a healthy lifestyle, including physical activity, a balanced diet, a moderate alcohol consumption and abstinence from smoking, are associated with large decreases in the incidence and mortality rates for the most common chronic diseases. That is why primary health care (PHC) services are trying, so far with less success than desirable, to promote healthy lifestyles among patients. The objective of this study is to design and model, under a participative collaboration framework between clinicians and researchers, interventions that are feasible and sustainable for the promotion of healthy lifestyles in PHC.

METHODS AND DESIGN

Phase I formative research and a quasi-experimental evaluation of the modelling and planning process will be undertaken in eight primary care centres (PCCs) of the Basque Health Service--OSAKIDETZA, of which four centres will be assigned for convenience to the Intervention Group (the others being Controls). Twelve structured study, discussion and consensus sessions supported by reviews of the literature and relevant documents, will be undertaken throughout 12 months. The first four sessions, including a descriptive strategic needs assessment, will lead to the prioritisation of a health promotion aim in each centre. In the remaining eight sessions, collaborative design of intervention strategies, on the basis of a planning process and pilot trials, will be carried out. The impact of the formative process on the practice of healthy lifestyle promotion, attitude towards health promotion and other factors associated with the optimisation of preventive clinical practice will be assessed, through pre- and post-programme evaluations and comparisons of the indicators measured in professionals from the centres assigned to the Intervention or Control Groups.

DISCUSSION

There are four necessary factors for the outcome to be successful and result in important changes: (1) the commitment of professional and community partners who are involved; (2) their competence for change; (3) the active cooperation and participation of the interdisciplinary partners involved throughout the process of change; and (4) the availability of resources necessary to facilitate the change.

Willingness to vaccinate and to be vaccinated in adults

Vaccination may be mandated by regulation, as in some national infant vaccination programs, encouraged by health authorities, as in 'Flu vaccine campaigns for adults aged 60 years and older, or linked to the informed decision of individuals. Other methods include promotion by incentives to general practitioners, and recommendations from healthcare workers. All these factors contribute to variable vaccine coverage between countries and between different age and socio-economic groups. Many other factors, including providers' patient-oriented interventions and reimbursement issues play an important role in determining the level of vaccine uptake in a given population for a particular disease. However, the first step in vaccination campaigns is to give motivating information to healthcare workers that the benefits of being vaccinated outweigh possible inconvenience or adverse reactions. The information must be complete and accurate.When it has been ascertained that this information is understood and accepted, a system providing cheap and easy vaccination must be organised. Special groups such as the house-bound will need particular attention, appropriate information, and be included in free vaccination schemes. It should be acknowledged that social pressure often influences (positively or negatively) the decision of the individual. Lastly, a massive but objective information campaign is needed for the whole population, each and every visit to a health clinic being treated as an opportunity to check vaccination status and to vaccinate immediately if necessary. Simultaneous vaccination with two or more vaccines increases the chances of reaching the required population cover.

Impact of mailed and automated telephone reminders on receipt of repeat mammograms: a randomized controlled trial

BACKGROUND

This study compares the efficacy of three types of reminders in promoting annual repeat mammography screening.

DESIGN

RCT.

SETTING AND PARTICIPANTS

Study recruitment occurred in 2004-2005. Participants were recruited through the North Carolina State Health Plan for Teachers and State Employees. All were aged 40-75 years and had a screening mammogram prior to study enrollment. A total of 3547 women completed baseline telephone interviews.

INTERVENTION

Prior to study recruitment, women were assigned randomly to one of three reminder groups: (1) printed enhanced usual care reminders (EUCRs); (2) automated telephone reminders (ATRs) identical in content to EUCRs; or (3) enhanced letter reminders that included additional information guided by behavioral theory. Interventions were delivered 2-3 months prior to women's mammography due dates.

MAIN OUTCOME MEASURES

Repeat mammography adherence, defined as having a mammogram no sooner than 10 months and no later than 14 months after the enrollment mammogram.

RESULTS

Each intervention produced adherence proportions that ranged from 72% to 76%. Post-intervention adherence rates increased by an absolute 17.8% from baseline. Women assigned to ATRs were significantly more likely to have had mammograms than women assigned to EUCRs (p=0.014). Comparisons of reminder efficacy did not vary across key subgroups.

CONCLUSIONS

Although all reminders were effective in promoting repeat mammography adherence, ATRs were the most effective and lowest in cost. Health organizations should consider using ATRs to maximize proportions of members who receive mammograms at annual intervals.

Home-based blood pressure interventions for blacks

Efforts to increase blood pressure (BP) control rates in blacks, a traditionally underserved high-risk population must address both provider practice and patient adherence issues. The home-based BP Intervention for blacks study is a 3-arm randomized controlled trial designed to test 2 strategies to improve hypertension management and outcomes in a decentralized service setting serving a vulnerable and complex home care population. The primary study outcomes are systolic BP, diastolic BP, and BP control; secondary outcomes are nurse adherence to hypertension management recommendations and patient adherence to medication, healthy diet, and other self-management strategies. Nurses (n=312) in a nonprofit Medicare-certified home health agency are randomized along with their eligible hypertensive patients (n=845). The 2 interventions being tested are (1) a "basic" intervention delivering key evidence-based reminders to home care nurses and patients while the patient is receiving traditional postacute home health care; and (2) an "augmented" intervention that includes that same as the basic intervention, plus transition to an ongoing Hypertension Home Support Program that extends support for 12 months. Outcomes are measured at 3 and 12 months after baseline interview. The interventions will be assessed relative to usual care and to each other. Systems change to improve BP management and outcomes in home health will not easily occur without new intervention models and rigorous evaluation of their impact. Results from this trial will provide important information on potential strategies to improve BP control in a low-income chronically ill patient population.

The effects of an area-based intervention on the uptake of maternal and child health assessments in Australia: a community trial

BACKGROUND

Recognition of the importance of the early years in determining health and educational attainment and promotion of the World Health Organization Health for All (HFA) principles has led to an international trend towards community-based initiatives to improve developmental outcomes among socio-economically disadvantaged children. In this study we examine whether, Best Start, an Australian area-based initiative to improve child health was effective in improving access to Maternal and Child Health (MCH) services.

METHODS

The study compares access to information, parental confidence and annual 3.5 year Ages and Stages visiting rates before (2001/02) and after (2004/05) the introduction of Best Start. Access to information and parental confidence were measured in surveys of parents with 3 year old children. There were 1666 surveys in the first wave and 1838 surveys in the second wave. The analysis of visiting rates for the 3.5 year Ages and Stages visit included all eligible Victorian children. Best Start sites included 1,739 eligible children in 2001/02 and 1437 eligible children in 2004/05. The comparable figures in the rest of the state were and 45, 497 and 45, 953 respectively.

RESULTS

There was a significant increase in attendance at the 3.5 year Ages and Stages visit in 2004/05 compared to 2001/02 in all areas. However the increase in attendance was significantly greater at Best Start sites than the rest of the state. Access to information and parental confidence improved over the course of the intervention in Best Start sites with MCH projects compared to other Best Start sites.

CONCLUSION

These results suggest that community-based initiatives in disadvantaged areas may improve parents' access to child health information, improve their confidence and increase MCH service use. These outcomes suggest such programmes could potentially contribute to strategies to reduce child health inequalities.

Determining use of preventive health care in Ontario: comparison of rates of 3 maneuvers in administrative and survey data

OBJECTIVE

To examine rates of influenza vaccination, mammography, and Papanicolaou smear by comparing data obtained from the Ontario Health Insurance Plan administrative database with rates as self-reported in the Canadian Community Health Survey.

DESIGN

Retrospective cohort study using data from Statistics Canada's 2000-2001 Canadian Community Health Survey and from the Ontario Health Insurance Plan administrative database for the same period.

SETTING

Ontario.

PARTICIPANTS

Those aged 12 and older who had received influenza vaccination, women aged 35 or older who had had mammograms within the past 2 years, and women aged 18 or older who had had Pap smears within the past 3 years who were surveyed during the Canadian Community Health Survey in 2001.

MAIN OUTCOME MEASURES

Rates of influenza vaccination, mammography, and Pap smear in Ontario's 14 Local Health Integration Networks by network, age group, and socioeconomic status.

RESULTS

Rates varied by health network. Analysis by age showed that influenza vaccination rates increased with age and peaked among those 75 and older. Rates of mammography screening increased with age but dropped substantially among those 75 and older. Rates of Pap smear peaked among those 20 to 39 and decreased with increasing age. Rates of mammography and Pap smear increased with rising socioeconomic status, but influenza vaccination rates did not differ substantially by socioeconomic status. Rates for all 3 preventive maneuvers were lower in the Ontario Health Insurance Plan data than in the self-reported Canadian Community Health Survey data.

CONCLUSION

There are obstacles to finding out the true rates of preventive health care use in Ontario. We need to ascertain these rates in order to establish a criterion standard for delivery of these services. Development of programs to target specific geographic locations, socioeconomic classes, and high-risk groups are needed to increase the overall use of preventive health services in Ontario.

Factors conditioning effectiveness of a reminder/recall system to improve influenza vaccination in asthmatic children

In order to verify whether a telephone recall system directly managed by pediatricians who usually follow up children for their asthma is more effective than an anonymous recall system, we randomly assigned 285 asthmatic children (177 males; mean age 10.3+/-3.4 years) to one of three groups: those whose mothers were to be called by a pediatrician not previously involved in caring for their asthmatic children and who received the vaccine in our immunisation clinic (group 1); those whose mothers were to be called by a pediatrician from our asthma clinic and who received the vaccine in the immunisation clinic (group 2); and those whose mothers were to be called by a pediatrician from our asthma clinic and who received the vaccine in the same clinic (group 3). Our findings highlight that the use of a reminder/recall system increases vaccination rates in asthmatic children, and show that the best results are obtained when the mothers are contacted and the vaccine administered by the pediatricians who usually follow up the child for asthma.

Reminder systems and late patient tracers in the diagnosis and management of tuberculosis

BACKGROUND

Reminder systems and late patient tracers as strategies to improve patients' adherence to tuberculosis screening, diagnosis, and treatment are used in some countries, but their effectiveness has not previously been systematically reviewed.

OBJECTIVES

To assess the effects of reminder systems and late patient tracers on completion of diagnostics, commencement of treatment in people referred for curative or prophylactic treatment of tuberculosis, completion of treatment in people starting curative or prophylactic treatment for tuberculosis, and cure in people being treated for active tuberculosis.

SEARCH STRATEGY

We searched the Cochrane Infectious Diseases Group Specialized Register (June 2008), Cochrane Effective Practice and Organization of Care Group Specialized Register (April 2007), CENTRAL (The Cochrane Library 2008, Issue 2), MEDLINE (1966 to June 2008), EMBASE (1974 to June 2008), LILACS (1982 to June 2008), CINAHL (1982 to June 2008), SCI-EXPANDED (1945 to June 2008), SSCI (1956 to June 2008), mRCT (June 2008), Indian Journal of Tuberculosis (1983 to June 2008), and reference lists. We also contacted researchers working in the field.

SELECTION CRITERIA

Randomized controlled trials (RCTs), including cluster RCTs and quasi-RCTs, and controlled before-and-after studies comparing any reminders or late patient tracers with no or other kinds of reminders or late patient tracers. We included people in any setting who require treatment for tuberculosis or require prophylaxis against tuberculosis and are referred to tuberculosis diagnostic or screening services.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed trial risk of bias and extracted data. No meta-analysis could be undertaken due to the heterogeneity of interventions across trials.

MAIN RESULTS

Nine trials involving 5257 participants met the inclusion criteria. Three assessed the use of late patient tracers, and six assessed reminder systems. Late patient tracers (home visit and letter) were shown to be beneficial in increasing adherence to tuberculosis treatment compared with no late patient tracer. The results from almost all the reminder trials, except one, show benefits of different types of reminders compared to no reminder on adherence to tuberculosis clinic appointments.

AUTHORS' CONCLUSIONS

The included trials show significantly better outcomes among those tuberculosis patients for which late patient tracers and reminders are used. Studies of good quality (large and with rigorous study design) are needed to decide the most effective late patient tracer actions and reminders in different settings. Future studies of reminders in chemoprophylaxis and treatment settings would be useful.

Supporting the delivery of cost-effective interventions in primary health-care systems in low-income and middle-income countries: an overview of systematic reviews

Strengthening health systems is a key challenge to improving the delivery of cost-effective interventions in primary health care and achieving the vision of the Alma-Ata Declaration. Effective governance, financial and delivery arrangements within health systems, and effective implementation strategies are needed urgently in low-income and middle-income countries. This overview summarises the evidence from systematic reviews of health systems arrangements and implementation strategies, with a particular focus on evidence relevant to primary health care in such settings. Although evidence is sparse, there are several promising health systems arrangements and implementation strategies for strengthening primary health care. However, their introduction must be accompanied by rigorous evaluations. The evidence base needs urgently to be strengthened, synthesised, and taken into account in policy and practice, particularly for the benefit of those who have been excluded from the health care advances of recent decades.

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.

Patient views on reminder letters for influenza vaccinations in an older primary care patient population: a mixed methods study

OBJECTIVES

To explore the perspectives of older adults on the acceptability of reminder letters for influenza vaccinations.

METHODS

We randomly selected 23 family physicians from each Family Health and Primary Care network participating in a demonstration project designed to increase the delivery of preventive services in Ontario. From the roster of each physician, we surveyed 35 randomly selected patients over 65 years of age who recently received a reminder letter regarding influenza vaccinations from their physician. The questionnaires sought patient perspectives on the acceptability and usefulness of the letter. We also conducted follow-up telephone interviews with a subgroup of respondents to explore some of the survey findings in greater depth.

RESULTS

85.3% (663/767) of patients completed the questionnaire. Sixty-five percent of respondents recalled receiving the reminder (n=431), and of those, 77.3% found it helpful. Of the respondents who recalled the letter and received a flu shot (n=348), 11.2% indicated they might not have done so without the letter. The majority of respondents reported that they would like to continue receiving reminder letters for influenza vaccinations (63.0%) and other preventive services (77.1%) from their family physician. The interview participants endorsed the use of reminder letters for improving vaccination coverage in older adults, but did not feel that the strategy was required for them personally.

CONCLUSIONS

The general attitude of older adults towards reminder letters was favourable, and the reminders appear to have contributed to a modest increase in influenza vaccination rates.

Prompting clinicians about preventive care measures: a systematic review of randomized controlled trials

Preventive care measures remain underutilized despite recommendations to increase their use. The objective of this review was to examine the characteristics, types, and effects of paper- and computer-based interventions for preventive care measures. The study provides an update to a previous systematic review. We included randomized controlled trials that implemented a physician reminder and measured the effects on the frequency of providing preventive care. Of the 1,535 articles identified, 28 met inclusion criteria and were combined with the 33 studies from the previous review. The studies involved 264 preventive care interventions, 4,638 clinicians and 144,605 patients. Implementation strategies included combined paper-based with computer generated reminders in 34 studies (56%), paper-based reminders in 19 studies (31%), and fully computerized reminders in 8 studies (13%). The average increase for the three strategies in delivering preventive care measures ranged between 12% and 14%. Cardiac care and smoking cessation reminders were most effective. Computer-generated prompts were the most commonly implemented reminders. Clinician reminders are a successful approach for increasing the rates of delivering preventive care; however, their effectiveness remains modest. Despite increased implementation of electronic health records, randomized controlled trials evaluating computerized reminder systems are infrequent.

Schedules for hepatitis B vaccination of risk groups: balancing immunogenicity and compliance

INTRODUCTION

Vaccination is an important tool in hepatitis B prevention. However, several vaccine doses are required to induce long-term protection. Several at-risk groups have difficulties in adhering to the standard vaccination schedule.

OBJECTIVES

This paper aims to review the use of accelerated hepatitis B vaccination schedules, in terms of immunogenicity and compliance.

RESULTS

Accelerated schedules (0.1.2.12 months) or super-accelerated schedules (0.7.21.360 days) have been shown to result in higher proportions of healthy vaccinees reaching anti-HBs antibody levels >or=10 IU/l more rapidly. A fourth completing dose is required to lift antibody levels to an equal height, as does a standard (0.1.6 months) schedule. Accelerated schedules do also increase the uptake of hepatitis B vaccine, that is the proportion of vaccinees who receive three doses. However, completing the schedule with a fourth dose is usually more difficult than completing a standard 0.1.6-month schedule. Several additional tools can help to increase the compliance (eg, reminder systems, outreach services and incentive schemes).

CONCLUSION

For rapid seroconversion and almost immediate protection in the short term, a (super)accelerated schedule could be used in at-risk groups. As long-term protection data with these (super) accelerated schedules have not been documented yet, a fourth dose at month 12 is still required. A shortened schedule (0.1.4 months) might be an alternative worth considering compared with the standard 0.1.6, as it convenes to internationally accepted minimum dose intervals and offers earlier protection. There is a clear need to study the long-term protection and effectiveness of the primary part of (super)accelerated schedules.

Improving influenza immunisation for high-risk children and adolescents

OBJECTIVE

To improve influenza vaccination rates for high-risk children and adolescents.

METHODS

During the 2004-5 influenza season, 5 regional cystic fibrosis (CF) centres, 6 hospital clinics that participated in a similar initiative the previous year, 4 new hospital clinics, and 39 community-based paediatric practices implemented a multicomponent change package consisting of nine improvement strategies designed to increase immunisation of high-risk patients. Each site was encouraged to adopt and customize the improvement strategies to meet their specific culture and needs. The main outcome measure was the proportion of the target population immunised. Surveys sent to the community practices were summarised.

RESULTS

The intervention targeted a total of 18 866 high-risk children and 9374 (49.7%) received the influenza vaccination. Community-based practices that actively participated in the collaborative reported using significantly more intervention strategies (mean (SD) 7.4 (2.3) vs 4.6 (1.5), respectively, p = 0.001) and achieved higher immunisation rates (59.3% (13.6%) vs 43.7% (20.5%), respectively, p = 0.01) than non-participating practices. The most frequently implemented change concepts were posters in the office, walk-in clinics or same-day appointments and reminder phone calls. The interventions deemed most helpful were weekend or evening "flu shot only" sessions, walk-in or same-day appointments, reminder calls and special mailings to families.

CONCLUSIONS

Implementation of the change package, based on evidence and diffusion of innovation theory, resulted in higher immunisation rates than typically reported in the medical literature, especially for the community-based primary care practices.

‘It's just the normal thing to do’: Exploring parental decision-making about the ‘five-in-one’ vaccine

This qualitative study explored parental decision-making about the DTaP/IPV/Hib 'five-in-one' vaccine. Semi-structured interviews were conducted with 22 parents of babies aged between 4 and 13 weeks old, recruited from four practices in southern England. A modified Grounded Theory approach identified that although parents had some concerns, most complied with the recommended programme rather than making an informed decision. Other themes related to perceived importance of immunisation; beliefs about how immunisation works; trust; perceptions of vulnerability; feelings of guilt and responsibility; and practicalities. It is important to explore how parents' attitudes change over the preschool years and to develop ways of addressing uncertainties about immunisation, including the safety of combining antigens and the need for boosters.

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.

The success of an immunization information system in the wake of Hurricane Katrina

Within days after Hurricane Katrina in September 2005, the Houston-Harris County Immunization Registry was connected to the Louisiana Immunization Network for Kids Statewide. This linkage provided immediate access to the immunization records of children who were forced to evacuate the New Orleans, Louisiana, area. One year later, >18,900 immunization records have been found, representing an estimated cost savings of more than $1.6 million for vaccine alone and $3.04 million for vaccine plus administration fees. This experience demonstrated the vital and previously unrecognized functionality of immunization information systems in a public health emergency. Here we describe the Houston-Harris County Immunization Registry's experience after Hurricane Katrina in terms of maximizing the use of immunization information systems and the implications of this experience for patients, providers, and public health for future disaster-preparedness planning.

Uptake of pneumococcal polysaccharide vaccine in at-risk populations in England and Wales 1999-2005

The UK has had a pneumococcal polysaccharide vaccination (PPV) programme for groups at higher risk of invasive disease since 1992. This paper presents data from a sample of primary-care practices (Q-RESEARCH) of PPV uptake in patients according to their risk status. Of 2.9 million registered patients in 2005, 2.1% were vaccinated with PPV in the preceding 12 months and 6.5% in the preceding 5 years. Twenty-nine per cent of the registered population fell into one or more risk groups. The proportion of each risk group vaccinated in the previous 5 years ranged from 69% (cochlear implants), 53.4% (splenic dysfunction), 36.5% (chronic heart disease), 34.7% (diabetes), 22.9% (immunosuppressed), 28.7% (chronic renal disease), 15.9% (sickle cell disease) to 12.6% (chronic respiratory disease). Uptake was lower in areas where the non-white proportion of population was >10%. In conclusion, there remain large gaps in the uptake of PPV in several high-risk populations in the United Kingdom. Effective strategies need to be developed to address these deficiencies.

Warned, but not well armed: preventing viral upper respiratory infections in households

ABSTRACT The purpose of this state‐of‐the‐science review was to identify strategies and household‐level interventions for public health nurses to help prevent the acquisition and spread of viral upper respiratory infections (URI) in the community. Even though viral URI are a major global economic and social problem, surprisingly little research has been conducted to attempt to prevent them or reduce their transmission, probably because URI (with the exception of epidemic influenza) are generally considered to be mild and self‐limited. Based on the research to date, public health nurses can use several promising strategies for prevention: (a) provide more tailored educational messages regarding preventive strategies such as vaccination, hand hygiene, spatial separation of infected household members, avoidance of antibiotics to treat viral URI, and environmental cleaning (e.g., for toys or other shared items), which are delivered personally rather than passively (e.g., pamphlets placed in a waiting room); (b) use each patient encounter in any setting to encourage influenza vaccination for relevant risk groups; (c) encourage use of alcohol hand sanitizers by household members during the cold and flu season; and (d) provide opportunities for skill development for adult and child household members (e.g., cover your cough, when to seek care or an antibiotic).

Influenza vaccine coverage and missed opportunities among inner-city children aged 6 to 23 months: 2000-2005

OBJECTIVE

In 2002, the Advisory Committee on Immunization Practices recommended universal influenza vaccination of 6- to 23-month-olds. Little is known about coverage and missed opportunities for influenza vaccination at inner-city practices. The objective of this study was to assess the 2000-2001 to 2004-2005 coverage and the prevalence of missed opportunities for influenza vaccination among inner-city children.

METHODS

We conducted a retrospective review for the 2000-2001 to 2004-2005 influenza seasons at a practice network in New York City. The study population included 5 annual cohorts of 6- to 29-month olds as of March 31 of each year with > or = 1 visit to the network in the previous 12 months (n = 7063). Immunization data were obtained from the network registry and the New York Citywide Immunization Registry. Coverage levels were estimated for 1 dose (partial) and 2 doses (full). Missed opportunities were assessed for visits within each influenza season.

RESULTS

Coverage rose steadily throughout the 5 years (full: 1.6% to 23.7%; partial: 1.5% to 18.1%). The relationship between year and coverage was linear. Missed opportunities occurred in 82% of visits and were more common for first (89%) than for repeat doses (38%). Missed opportunities per child per season decreased from 2.9 to 2.0 during the study period.

CONCLUSIONS

Influenza vaccine coverage among 6- to 23-month-olds at inner-city practices increased steadily from 2000-2001 through 2004-2005, and the prevalence of missed opportunities per child decreased. However, coverage remained suboptimal, with most of children not vaccinated or undervaccinated. Missed opportunities were major contributors to low coverage.

Impact of the 2004 influenza vaccine shortage on repeat immunization rates

PURPOSE

We assessed the impact of the severe influenza vaccine shortage of 2004 on individual physicians' immunization performance.

METHODS

Using 1998-2004 Medicare claims data, we monitored the physician continuity rate (proportion of patients receiving influenza immunization from a physician in 1 year who received a subsequent immunization from the same physician the subsequent year) and other clinician rate (proportion of patients with claims from 1 physician in 1 year with a claim from another clinician the subsequent year) in West Virginia Medicare beneficiaries from 2000-2004. We examined vaccine claim trends by clinician and surveys of self-reported immunization to determine whether patients received vaccine from nonphysician clinicians or went without immunization each year.

RESULTS

Claims-based influenza vaccination rates increased from 35.5% to 41.3% from 2000-2003, reflecting historical trends, before declining 14.1% in 2004. Median continuity rates among the 723 to 849 physicians claiming 25 or more influenza immunizations from 2000-2003 increased from 47% in 2000-2001 to 54% in 2002-2003; then fell to 3% in 2003-2004. The number of physicians filing 100 or more claims declined from 337 in 2003 to 130 in 2004. More than 25% of physicians had no repeat vaccinations of the same beneficiaries in 2004. Trends in clinician type and survey data indicated a shift of many beneficiaries to mass vaccinators and institutional providers; however, compared with previous years, there was an estimated 8% increase in 2004 in the number of West Virginia beneficiaries who did not receive vaccine.

CONCLUSIONS

The 2004 vaccine shortage had a severe impact on influenza immunization rates in private physician's offices, disrupting continuity of care.

Factors underlying suboptimal childhood immunisation

This review considers possible reasons behind parents' missed vaccination opportunities in the context of the latest immunisation coverage rates for England. Suboptimal uptake is not exclusive to measles, mumps and rubella (MMR). A substantial proportion of children also miss diphtheria, tetanus and polio vaccination. For MMR and diphtheria, tetanus and polio, uptake of primary plus booster immunisation is lower than for the primary course alone. Several reasons for suboptimal uptake are identified from the international literature. These provide insights into parental decision-making and potential barriers to immunisation that may need to be addressed in efforts to improve coverage rates.

Patient reminder and patient recall systems to improve immunization rates

BACKGROUND

Immunization rates for children and adults are rising, but coverage levels have not reached optimal goals. As a result of low immunization rates, 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 physicians, it is important to understand and promote interventions that work in primary care settings to increase immunization coverage. A common theme across immunization programs in all nations involves the challenge of determining the denominator of eligible recipients (e.g. all children who should receive the measles vaccine) and identifying the best strategy to ensure high vaccination rates. Strategies have focused on patient-oriented interventions (e.g., patient reminders), provider interventions and system interventions. One intervention strategy involves patient reminder and recall systems.

OBJECTIVES

To assess the effectiveness of patient reminder and recall systems in improving immunization rates and compare the effects of various types of reminders in different settings or patient populations.

SEARCH STRATEGY

A systematic search was performed for the initial review using MEDLINE (1966-1998) and four other bibliographic databases: EMBASE, PsychINFO, Sociological Abstracts, and CAB Abstracts. Authors also performed a search of The Effective Practice and Organisation of Care (EPOC) register in April 2001 to update the review. Two authors reviewed the lists of titles and abstracts and used the inclusion criteria to mark potentially relevant articles for full review. The reference lists of all relevant articles and reviews were back searched for additional studies. Publications of abstracts, proceedings from scientific meetings and files of study collaborators were also searched for references. In December 2004 the EPOC register was searched to identify relevant articles to update the review.

STUDY DESIGN

Randomized controlled trials (RCT), controlled before and after studies (CBA) and interrupted time series (ITS) studies written in English.

TYPES OF PARTICIPANTS

Health care personnel who deliver immunizations and children (birth to 18 years) or adults (18 years and up) who receive immunizations in any setting.

TYPES OF INTERVENTIONS

Any intervention that falls within the EPOC scope (See Group Details) and that includes patient reminder or recall systems, or both, in at least one arm of the study.

TYPES OF OUTCOME MEASURES

Immunization rates or the proportion of the target population up-to-date on recommended immunizations. Outcomes were acceptable for either individual vaccinations (e.g. influenza vaccination) or standard combinations of recommended vaccinations (e.g. all recommended vaccinations by a specific date or age).

DATA COLLECTION

Each study was read independently by two reviewers. Disagreements between reviewers were resolved by a formal reconciliation process to achieve consensus.

ANALYSIS

Results are presented for individual studies as relative rates for randomized controlled trials and as absolute changes in percentage points for controlled before and after studies. Pooled results for RCTs only were presented using the random effects model.

MAIN RESULTS

Five new studies were added for this update. Increases in immunization rates due to reminders were in the range of 1 to 20 percentage points. Reminders were effective for childhood vaccinations (OR = 1.45, 95% CI =1.28, 1.66), childhood influenza vaccinations (OR = 2.87, 95% CI = 1.65, 4.98), adult pneumococcus, tetanus, and Hepatitis B (OR = 2.19, 95% CI = 1.21, 3.99), and adult influenza vaccinations (OR = 1.66, 95% CI = 1.31, 2.09). All types of reminders were effective (postcards, letters, telephone or autodialer calls), with telephone being the most effective but most costly.

AUTHORS' CONCLUSIONS

Patient reminder and recall systems in primary care settings are effective in improving immunization rates within developed countries.
