Determinants of influenza and pertussis vaccine uptake in pregnant women in Ireland: A cross-sectional survey in 2017/18 influenza season.

In Ireland seasonal influenza and pertussis vaccination during pregnancy is recommended and every year national campaigns are organised to raise awareness and improve uptake. We estimated influenza and pertussis vaccine uptake and identified factors associated with vaccination status in pregnant women in 2017/18. We conducted a face-to-face omnibus survey, with quota sampling, among women aged 18-55 years and collected socio-demographic characteristics, self-reported vaccination status, awareness of vaccine campaigns, and attitudes towards vaccination. Sample was weighted to ensure representativeness with the target population. We performed univariate and multivariable logistic regression analyses on survey data. Overall, 241 pregnant women were enrolled. Influenza and pertussis vaccine uptake was 61.7% and 49.9%, respectively. Awareness of vaccine campaign and socio-economic status (SES) were associated with both influenza and pertussis vaccine uptake. The association between SES and uptake of vaccines differed by awareness. Women aware of the influenza vaccine campaign and with mid and low SES were less likely to be vaccinated, compared to those with high SES (aOR = 0.46; 95%CI: 0.22-0.97; aOR = 0.27; 95%CI: 0.12-0.60, respectively); women not aware of the pertussis vaccine campaign and with mid and low SES were less likely to be vaccinated, compared to those aware and with high SES (aOR = 0.15; 95%CI: 0.04-0.48; aOR = 0.05; 95%CI: 0.01-0.24, respectively). General practitioner (GP) recommendation was the main reason for receiving influenza vaccine (39.2%), and 71.8% of women were recommended pertussis vaccination from their GPs. The survey reports moderate uptake of vaccines among pregnant women, inequalities in uptake by SES and identifies GPs as primary source for vaccine recommendation. We recommend multifaceted campaigns, by engaging GPs, to target all socio-economic groups.

Is It Time To Review The Vaccination Strategy To Protect Adults Against Invasive Pneumococcal Disease?

Pneumococcal conjugate vaccines (PCVs) have reduced the predominant serotypes causing invasive pneumococcal disease (IPD). We assessed the impact of the paediatric 7- and 13-valent pneumococcal conjugate vaccines (PCV7 and PCV13) among older adults. We compared serotype-specific incidence rates from 2007/08 to 2016/17, expressed as incidence rate ratios (IRR). Introducing PCV7 and PCV13 into the childhood immunisation programme resulted in a decline in these serotypes in adults ≥65 years of age, with PCV7 serotypes decreasing by 85% (IRR=0.11, 95%CI: 0.05-0.22, p<0.0001) and PCV13 serotypes not included in PCV7 (PCV13-7), decreasing by 9% (IRR=0.68, 95%CI: 0.40-1.16, p=0.134). However, there was a significant increase in serotypes only found in the 23-valent polysaccharide vaccine, PPV23-PCV13: IRR=2.57, 95%CI: 1.68-4.03, p<0.0001, and non-vaccine types (NVTs), IRR=3.33, 95%CI: 1.75-6.84, p=0.0001. The decline of IPD associated with PCV7/13 serotypes and the increase in PPV23-PCV13 serotypes indicates clear serotype replacement. Increasing PPV23 uptake could still reduce the burden of disease for this population.

A retrospective assessment of the completeness and timeliness of meningococcal disease notifications in the Republic of Ireland over a 16-year period, 1999-2015.

OBJECTIVES: To assess how invasive meningococcal disease (IMD) records held by the Irish Meningitis & Sepsis Reference Laboratory (IMSRL) compare to records of IMD notifications reported on the national integrated electronic Computerised Infectious Disease Reporting (CIDR) system. STUDY DESIGN: We assessed the completeness, data quality and timeliness of IMD notifications and reference laboratory records for the period between 01 July 1999 and 30 June 2015 by identifying discrepant and/or missing data items in a matched case data set and by measuring the timeliness of case reporting. METHODS: We matched anonymised cases notified to CIDR to records based at the IMSRL using birth, reporting and onset dates with gender and laboratory parameters of meningococcal strain characteristics and method of confirmation. Completeness, data quality and the timeliness of notifications were assessed by a stratified sensitivity-based technique and by calculating the average difference between IMSRL and CIDR reporting dates. RESULTS: CIDR recorded a total of 3163 notifications, of which 2759 (87.2%) were matched to IMSRL records. Completeness of IMD case classification as confirmed was estimated to be >99%. Examining the levels of discrepant or missing data in both matched CIDR and IMSRL records as a measure of data quality, recording of demographic items and meningococcal group showed least differences, recording of laboratory case confirmation method and meningococcal strain characteristics were less well recorded, with detail on clinical presentation/diagnosis least well recorded. Overall average annual difference between CIDR and IMSRL recording dates was 3.2 days (95% confidence interval 2.6-3.8). CONCLUSIONS: A high quality of IMD surveillance in Ireland was demonstrated, but scope for improvements in timeliness and capture of enhanced surveillance data regarding date of onset and strain-specific characteristics were identified.

The Uptake of Human Papillomavirus Vaccine In Irish Schools: The Impact Of Disadvantage.

HPV vaccine Gardasil© is offered to girls in first year of secondary school in Ireland. We aimed to determine the association between HPV vaccine uptake among girls for academic year 2013/2014, by school and school characteristics: socioeconomic disadvantage and religious ethos. The National Schools Immunisation System (SIS) was searched to determine HPV vaccine uptake in schools for 2013/2014 (prior to recent anti-HPV vaccine publicity). The disadvantaged status and ethos of each school was added to the report. In total 577 schools were identified. Mean vaccine uptake was 83.7%. Disadvantaged schools had a lower mean uptake (%) than other schools (79.4% vs 85.0%, difference 5.58%, 95%CI 2.69-8.21) and were twice as likely to have an uptake of ?50% (OR 2.07, 95% CI 2.76 - 5.18). No difference was found between schools of different ethoses. HPV vaccine uptake is lower in disadvantaged Irish schools. Policies should be developed to ensure a more equitable uptake of HPV vaccine.

Seasonal influenza vaccine uptake in HSE-funded hospitals and nursing homes during the 2011/2012 influenza season.

Annual seasonal influenza vaccine is recommended for all health care workers (HCWs) in Ireland. For the 2011/2012 influenza season, information was collected on influenza vaccination uptake among HCWs employed in Health Service Executive (HSE)-funded hospitals (primarily acute) and of nursing homes (NHs) and also among NH long-term and short-term respite care residents. Forty-five hospitals (80%) and 120 NHs (75%) provided uptake data. Nationally, influenza vaccine uptake among hospital employed HCWs was estimated to be 18% and 14% among HCWs in NHs; in NHs vaccine uptake among long-term care residents was estimated to 88%. These findings highlight the continued low uptake among HCWs of all categories and demonstrate the need for sustained measures to improve uptake rates.

Influenza A(H1N1)pdm09 vaccination policies and coverage in Europe.

In August 2010 the Vaccine European New Integrated Collaboration Effort (VENICE) project conducted a survey to collect information on influenza A(H1N1)pdm09 vaccination policies and vaccination coverage in the European Union (EU), Norway and Iceland. Of 29 responding countries, 26 organised national pandemic influenza vaccination and one country had recommendations for vaccination but did not have a specific programme. Of the 27 countries with vaccine recommendations, all recommended it for healthcare workers and pregnant women. Twelve countries recommended vaccine for all ages. Six and three countries had recommendations for specific age groups in children and in adults, countries for specific adult age groups. Most countries recommended vaccine for those in new risk groups identified early in the pandemic such as morbid obese and people with neurologic diseases. Two thirds of countries started their vaccination campaigns within a four week period after week 40/2009. The reported vaccination coverage varied between countries from 0.4% to 59% for the entire population (22 countries); 3% to 68% for healthcare workers (13 countries); 0% to 58% for pregnant women (12 countries); 0.2% to 74% for children (12 countries). Most countries identified similar target groups for pandemic vaccine, but substantial variability in vaccination coverage was seen. The recommendations were in accordance with policy advice from the EU Health Security Committee and the World Health Organization.

The current state of introduction of human papillomavirus vaccination into national immunisation schedules in Europe: first results of the VENICE2 2010 survey.

The Venice 2 human papillomavirus vaccination survey evaluates the state of introduction of the HPV vaccination into the national immunisation schedules in the 29 participating countries. As of July 2010, 18 countries have integrated this vaccination. The vaccination policy and achievements vary among those countries regarding target age groups, delivery infrastructures and vaccination coverage reached. Financial constraints remain the major obstacle for the 11 countries who have not yet introduced the vaccination.

Fitness costs associated with mounting a social immune response.

Social immune systems comprise immune defences mounted by individuals for the benefit of others (sensuCotter & Kilner 2010a). Just as with other forms of immunity, mounting a social immune response is expected to be costly but so far these fitness costs are unknown. We measured the costs of social immunity in a sub-social burying beetle, a species in which two or more adults defend a carrion breeding resource for their young by smearing the flesh with antibacterial anal exudates. Our experiments on widowed females reveal that a bacterial challenge to the breeding resource upregulates the antibacterial activity of a female's exudates, and this subsequently reduces her lifetime reproductive success. We suggest that the costliness of social immunity is a source of evolutionary conflict between breeding adults on a carcass, and that the phoretic communities that the beetles transport between carrion may assist the beetle by offsetting these costs.

National seasonal influenza vaccination survey in Europe, 2008.

A cross-sectional survey was undertaken with the European Union (EU) Member States and Norway and Iceland to describe seasonal influenza immunisation in the 2006-7 season, in particular to identify country-specific recommendations for risk groups, obtain vaccine uptake information and allow comparison with global recommendations. A standardised questionnaire was completed electronically by each country's project gatekeeper. Of the 29 countries surveyed, 28 recommended seasonal influenza vaccination for older age groups (22 for those aged > 65 years), and in one country vaccine was recommended for all age groups. All countries recommended vaccinating patients with chronic pulmonary and cardiovascular diseases and most countries advised to immunise patients with haematologic or metabolic disorders (n=28), immunologic disorders (n=27) and renal disease (n=27), as well as residents of long-term care facilities (n=24). Most countries recommended vaccination for staff in hospitals (n=25), long-term care facilities (n=25) and outpatient clinics (n=23), and one-third had such recommendations for workers in essential (n=10), military (n=10) and veterinary services (n=10) and poultry industry (n=13). Eight countries recommended vaccine for pregnant women; and five advised to vaccinate children (with age limits ranging from 6 months to 5 years). Twenty countries measured influenza vaccine uptake among those aged > 65 years (range 1.8%-82.1%), seven reported uptake in healthcare workers (range 14%-48%) and seven assessed coverage in persons with underlying medical conditions (range 27.6%-75.2%). The data provided by this study can assist EU states to assess and compare their influenza vaccination programme performance with other countries. The information provides a comprehensive overview of policies and programmes and their outcomes and can be used to inform joint discussions on how the national policies in the EU might be standardised in the future to achieve optimal coverage. Annual surveys could be used to monitor changes in these national policies.

Clinical service organisation for heart failure.

BACKGROUND: Chronic heart failure (CHF) is a serious, common condition associated with frequent hospitalisation. Several different disease management interventions (clinical service organisation interventions) for patients with CHF have been proposed. OBJECTIVES: To assess the effectiveness of disease management interventions for patients with CHF. SEARCH STRATEGY: We searched: Cochrane CENTRAL Register of Controlled Trials (to June 2003); MEDLINE (January 1966 to July 2003); EMBASE (January 1980 to July 2003); CINAHL (January 1982 to July 2003); AMED (January 1985 to July 2003); Science Citation Index Expanded (searched January 1981 to March 2001); SIGLE (January 1980 to July 2003); DARE (July 2003); National Research Register (July 2003); NHS Economic Evaluations Database (March 2001); reference lists of articles and asked experts in the field. SELECTION CRITERIA: Randomised controlled trials comparing disease management interventions specifically directed at patients with CHF to usual care. DATA COLLECTION AND ANALYSIS: At least two reviewers independently extracted data information and assessed study quality. Study authors were contacted for further information where necessary. MAIN RESULTS: Sixteen trials involving 1,627 people were included. We classified the interventions into three models: multidisciplinary interventions (a holistic approach bridging the gap between hospital admission and discharge home delivered by a team); case management interventions (intense monitoring of patients following discharge often involving telephone follow up and home visits); and clinic interventions (follow up in a CHF clinic). There was considerable overlap within these categories, however the components, intensity and duration of the interventions varied. Case management interventions tended to be associated with reduced all cause mortality but these findings were not statistically significant (odds ratio 0.86, 95% confidence interval 0.67 to 1.10, P = 0.23), although the evidence was stronger when analysis was limited to the better quality studies (odds ratio 0.68, 95% confidence interval 0.46 to 0.98, P = 0.04). There was weak evidence that case management interventions may be associated with a reduction in admissions for heart failure. It is unclear what the effective components of the case management interventions are. The single RCT of a multidisciplinary intervention showed reduced heart-failure related re-admissions in the short term. At present there is little available evidence to support clinic based interventions. AUTHORS' CONCLUSIONS: The data from this review are insufficient for forming recommendations. Further research should include adequately powered, multi-centre studies. Future studies should also investigate the effect of interventions on patients' and carers' quality of life, their satisfaction with the interventions and cost effectiveness.

Costs of resistance: genetic correlations and potential trade-offs in an insect immune system.

Theory predicts that natural selection will erode additive genetic variation in fitness-related traits. However, numerous studies have found considerable heritable variation in traits related to immune function, which should be closely linked to fitness. This could be due to trade-offs maintaining variation in these traits. We used the Egyptian cotton leafworm, Spodoptera littoralis, as a model system to examine the quantitative genetics of insect immune function. We estimated the heritabilities of several different measures of innate immunity and the genetic correlations between these immune traits and a number of life history traits. Our results provide the first evidence for a potential genetic trade-off within the insect immune system, with antibacterial activity (lysozyme-like) exhibiting a significant negative genetic correlation with haemocyte density, which itself is positively genetically correlated with both haemolymph phenoloxidase activity and cuticular melanization. We speculate on a potential trade-off between defence against parasites and predators, mediated by larval colour, and its role in maintaining genetic variation in traits under natural selection.

Models of hospital drug policy in the UK.

OBJECTIVES: Pharmacists in UK National Health Service (NHS) hospitals have a long tradition of involvement in the development of drug policy. This paper describes various approaches that have been employed in the development and implementation of drug policy in hospitals and examines the evidence for their effectiveness and acceptability in the context of a changing health service. METHODS: A series of focused interviews was conducted with a range of staff, including doctors, nurses, pharmacists and managers at eight hospitals. Interview sites were selected on the basis of a national survey of clinical pharmacy roles and were broadly representative of UK NHS hospitals. Interview data were analysed using constant comparison and analytic induction. RESULTS: Three models used in the development of drug policy were identified: a 'traditional' model, in which a drug and therapeutics committee establishes a hospital-wide formulary which is implemented by pharmacists; a 'combined' model, in which there is much more emphasis on tailoring policies and feedback to specialties or clinical directorates; and a 'medical control' model, in which prescribing decisions are made by individual doctors without reference to explicit policies and with little active pharmacy involvement. Pharmacy involvement was seen as vital to the development of effective policies but hospital-specific factors influenced the choice of model at particular sites. CONCLUSIONS: Hospitals may be moving towards the 'combined' model which could have advantages in the current internal market within the NHS. However, evaluations of the various approaches to drug policy should help inform this decision.

Who decides which pharmacy services are provided in UK National Health Service hospitals?

An interview survey of 129 UK National Health Service doctors, nurses, pharmacists and managers at eight acute care hospitals was conducted in 1994. The survey examined several topics including whether the introduction of the internal market had affected hospital pharmacy services and what those effects had been. An internal market has been introduced and it has had significant effects on the nature and structure of hospital pharmacy services. Directorate pharmacy services were available at six sites. Contracts for specific, usually novel, services had been implemented at one site and contracts had been introduced widely at another hospital. However, all the features of a market were not present at any site. Market orientation also has implications for the equity of service provision, primarily because decision-making regarding service provision is increasingly in the hands of the clinical directors, rather than pharmacy managers. The effects of this change are not yet clear.

[Mortality by age and cause of death in Switzerland: an analysis of cantonal disparities during the period 1978/83-1988/93]. / Mortalite par age et cause de deces en Suisse: une analyse des disparites cantonales durant la periode 1978/83 a 1988/93.

PIP: "During the 1980s, expectation of life at birth increased in all the Swiss cantons, but at very different tempi. The characteristics of the level and trends of mortality in the cantons are described here by the decomposition methods developed by Pollard and Arriaga. The pace of the development of mortality in the cantons is compared, and the particular characteristics observed are accounted for by life table analysis according to age and cause of death. The results show in particular the dominant role [of] economically active ages and beyond in recent mortality trends, and the importance of AIDS and of violent deaths in accounting for differences between cantons."

Hospital pharmacists' participation in audit in the United Kingdom.

OBJECTIVE: To investigate systematically participation in audit of NHS hospital pharmacists in the United Kingdom. DESIGN: Questionnaire census survey. SETTING: All NHS hospital pharmacies in the UK providing clinical pharmacy services. SUBJECTS: 462 hospital pharmacies. MAIN MEASURES: Extent and nature of participation in medical, clinical, and pharmacy audits according to hospital management and teaching status, educational level and specialisation of pharmacists, and perceived availability of resources. RESULTS: 416 questionnaires were returned (response rate 90%). Pharmacists contributed to medical audit in 50% (204/410) of hospitals, pharmacy audit in 27% (108/404), and clinical audit in only 7% (29/404). Many pharmacies (59% (235/399)) were involved in one or more types of audit but few (4%, (15/399)) in all three. Participation increased in medical and pharmacy audits with trust status (medical audit: 57% (65/115) trust hospital v 47% (132/281) non-trust hospital; pharmacy audit: 34% (39/114) v 24% (65/276)) and teaching status (medical audit: 58% (60/104) teaching hospital v 47% (130/279) non-teaching hospital; pharmacy audit 30% (31/104) v 25% (68/273)) and similarly for highly qualified pharmacists (MPhil or PhD, MSc, diplomas) (medical audit: 54% (163/302) with these qualifications v 38% (39/103) without; pharmacy audit: 32% (95/298) v 13% (13/102)) and specialists pharmacists (medical audit: 61% (112/184) specialist v 41% (90/221) non-specialist; pharmacy audit: 37% (67/182) v 19% (41/218)). Pharmacies contributing to medical audit commonly provided financial information on drug use (86% 169/197). Pharmacy audits often concentrated on audit of clinical pharmacy services. CONCLUSION: Pharmacists are beginning to participate in the critical evaluation of health care, mainly in medical audit.

Low-flow anaesthesia. Practice, cost implications and acceptability.

An 8-week survey was conducted to determine whether the introduction of low-flow anaesthesia (a fresh gas flow of 4 litres/minute or less) into routine use would be acceptable to members of a representative anaesthetic department and if the consequent reduction in use of volatile anaesthetics would result in financial savings. The hourly consumption of the volatile agents was measured during anaesthesia conducted using either conventional or low fresh gas flows. Anaesthetists' acceptance of low-flow anaesthesia was assessed using a questionnaire. Data were gathered on 286 patients undergoing inhalational anaesthesia for routine operative procedures. A 54.7% reduction in the consumption of isoflurane and a 55.9% reduction in that of enflurane was found. Of the 28 anaesthetists at the hospital, 21 would use low-flow anaesthesia routinely. The routine use of low-flow anaesthesia would therefore be acceptable and could result in annual savings of 26,870 pounds at Northwick Park Hospital.

Increasing prevalence of breast-feeding.

Two studies were performed to gauge the prevalence of and attitudes towards breast-feeding. Mothers delivered in one month in 1975 and in one month in 1977 were sent a questionnaire one month later to determine whether they were breast-feeding their babies; those that were received a second questionnaire at three months. The prevalence of breast-feeding increased significantly between 1975 and 1977, and in both periods primiparas were more likely to breast-feed than multiparas. A survey of mothers' intentions to breast-feed showed that there were no significant racial differences, but that 82% of women in social classes I and II intended to breast-feed compared with 54% in classes IV and V. These results show that, although the level of breast-feeding was high in 1975, a campaign directed at mothers, doctors, midwives, and health visitors did increase the prevalence of breast-feeding.
