RESUMO

OBJECTIVE: Many sub-Saharan African countries have massively scaled-up their antiretroviral treatment (ART) programmes, but many national programmes still show large gaps in paediatric ART coverage making it challenging to reduce AIDS-related deaths among HIV-infected children. We sought to identify enablers of paediatric ART coverage in Africa by examining the relationship between paediatric ART coverage and socioeconomic parameters measured at the population level so as to accelerate reaching the 90-90-90 targets. METHODS: Ecological analyses of paediatric ART coverage and socioeconomic indicators were performed. The data were obtained from the United Nations agencies and Forum for a new World Governance reports for the 21 Global Plan priority countries in Africa with highest burden of mother-to-child HIV transmission. Spearman's correlation and median regression were utilized to explore possible enablers of paediatric ART coverage. RESULTS: Factors associated with paediatric ART coverage included adult literacy (r=0.6, p=0.004), effective governance (r=0.6, p=0.003), virology testing by 2 months of age (r=0.9, p=0.001), density of healthcare workers per 10,000 population (r=0.6, p=0.007), and government expenditure on health (r=0.5, p=0.046). The paediatric ART coverage had a significant inverse relationship with the national mother-to-child transmission (MTCT) rate (r=-0.9, p<0.001) and gender inequality index (r=-0.6, p=0.006). Paediatric ART coverage had no relationship with poverty and HIV stigma indices. CONCLUSIONS: Low paediatric ART coverage continues to hamper progress towards eliminating AIDS-related deaths in HIV-infected children. Achieving this requires full commitment to a broad range of socioeconomic development goals.

RESUMO

BACKGROUND: Gastroenteritis (GE) causes significant morbidity, especially in young children. A vaccine against rotavirus, a common cause of viral GE (vGE), was added to the childhood immunization schedule in the UK in July 2013 and further related vaccines are under development. AIM: To explore parents' beliefs about vGE and their attitudes towards vaccinating. DESIGN AND SETTING: Qualitative interview study with parents of children who had recently experienced an episode of GE. METHOD: Twenty-eight semi-structured interviews were conducted over the phone with parents. Interviews were audio-recorded, transcribed and analysed using standard thematic approaches. RESULTS: Parents varied in their perception of the threat posed by GE, and parents who did not perceive GE as serious were less enthusiastic about vaccines. Other parents were supportive of vaccines in general and considered benefits to their child, their family and the wider community. Many parents said that they lacked knowledge about efficacy and effectiveness of GE vaccines but their underlying belief about the seriousness of illness motivated their attitudes. CONCLUSION: Acceptability of GE vaccines to parents could be improved by providing more information on both the burden of illness and the impact of rotavirus vaccine in other comparable countries.

RESUMO

OBJECTIVES: To estimate, overall and by organism, the incidence of infectious intestinal disease (IID) in the community, presenting to general practice (GP) and reported to national surveillance. DESIGN: Prospective, community cohort study and prospective study of GP presentation conducted between April 2008 and August 2009. SETTING: Eighty-eight GPs across the UK recruited from the Medical Research Council General Practice Research Framework and the Primary Care Research Networks. PARTICIPANTS: 6836 participants registered with the 88 participating practices in the community study; 991 patients with UK-acquired IID presenting to one of 37 practices taking part in the GP presentation study. MAIN OUTCOME MEASURES: IID rates in the community, presenting to GP and reported to national surveillance, overall and by organism; annual IID cases and GP consultations by organism. RESULTS: The overall rate of IID in the community was 274 cases per 1000 person-years (95% CI 254 to 296); the rate of GP consultations was 17.7 per 1000 person-years (95% CI 14.4 to 21.8). There were 147 community cases and 10 GP consultations for every case reported to national surveillance. Norovirus was the most common organism, with incidence rates of 47 community cases per 1000 person-years and 2.1 GP consultations per 1000 person-years. Campylobacter was the most common bacterial pathogen, with a rate of 9.3 cases per 1000 person-years in the community, and 1.3 GP consultations per 1000 person-years. We estimate that there are up to 17 million sporadic, community cases of IID and 1 million GP consultations annually in the UK. Of these, norovirus accounts for 3 million cases and 130,000 GP consultations, and Campylobacter is responsible for 500,000 cases and 80,000 GP consultations. CONCLUSIONS: IID poses a substantial community and healthcare burden in the UK. Control efforts must focus particularly on reducing the burden due to Campylobacter and enteric viruses.

RESUMO

OBJECTIVES: To investigate the association between hospital presentation for paediatric pneumonia or empyema and prior antibiotic use for respiratory tract infection (RTI). METHODS: Case-control study of children aged 6 months to 16 years presenting to hospital with radiographic evidence of pneumonia or empyema and a history of general practitioner (GP) consultation for the index illness. Cases were recruited from seven hospitals in South Wales between October 2008 and December 2009. Controls were children from the same age group who were diagnosed with an uncomplicated RTI in general practice in the same area and at a similar time of year. Primary data were collected from carers by a self-complete questionnaire, with a subsample compared against general practice records. RESULTS: We recruited 89 eligible cases and 166 eligible controls. Cases were less likely than controls to have been prescribed antibiotics at the first GP consultation for the index illness [odds ratio (OR) 0.53; 95% confidence interval (95% CI) 0.31-0.90]. Stratified analyses revealed that this association was limited to children who consulted a GP <3 days after illness onset (OR 0.23; 95% CI 0.10-0.50). Cases were also less likely to have taken antibiotics before the date of index hospital presentation, but this finding was not statistically significant after adjustment for confounding factors (adjusted OR 0.84; 95% CI 0.47-1.49). CONCLUSIONS: Antibiotics prescribed at the first GP consultation for an RTI may protect against subsequent hospital presentation for pneumonia or empyema in some children. Given the strong rationale against unnecessary antibiotic prescribing, further research is needed to identify which children are most likely to benefit from early antibiotic treatment.

RESUMO

We describe the first confirmed person-to-person transmission of oseltamivir-resistant pandemic influenza A(H1N1) 2009 virus that occurred in a hematology unit in the United Kingdom. Eleven cases of (H1N1) 2009 virus infection were identified, of which, ten were related as shown by sequence analysis of the hemagglutinin and neuraminidase genes. H275Y analysis demonstrated that 8 of 10 case patients had oseltamivir-resistant virus, with 4 of 8 case patients infected by direct transmission of resistant virus. Zanamivir should be considered as first-line therapy for influenza in patients with lymphopenic hematological conditions and uptake of influenza vaccination encouraged to further reduce the number of susceptible individuals.

RESUMO

BACKGROUND: Herd immunity is important in the effectiveness of conjugate polysaccharide vaccines against encapsulated bacteria. A large multicenter study investigated the effect of meningococcal serogroup C conjugate vaccine introduction on the meningococcal population. METHODS: Carried meningococci in individuals aged 15-19 years attending education establishments were investigated before and for 2 years after vaccine introduction. Isolates were characterized by multilocus sequence typing, serogroup, and capsular region genotype and changes in phenotypes and genotypes assessed. RESULTS: A total of 8462 meningococci were isolated from 47 765 participants (17.7%). Serogroup prevalence was similar over the 3 years, except for decreases of 80% for serogroup C and 40% for serogroup 29E. Clonal complexes were associated with particular serogroups and their relative proportions fluctuated, with 12 statistically significant changes (6 up, 6 down). The reduction of ST-11 complex serogroup C meningococci was probably due to vaccine introduction. Reasons for a decrease in serogroup 29E ST-254 meningococci (from 1.8% to 0.7%) and an increase in serogroup B ST-213 complex meningococci (from 6.7% to 10.6%) were less clear. CONCLUSIONS: Natural fluctuations in carried meningococcal genotypes and phenotypes a can be affected by the use of conjugate vaccines, and not all of these changes are anticipatable in advance of vaccine introduction.

RESUMO

OBJECTIVE: To identify ethnic differences in proportion positive for SARS-CoV-2, and proportion hospitalised, proportion admitted to intensive care and proportion died in hospital with COVID-19 during the first epidemic wave in Wales. DESIGN: Descriptive analysis of 76 503 SARS-CoV-2 tests carried out in Wales to 31 May 2020. Cohort study of 4046 individuals hospitalised with confirmed COVID-19 between 1 March and 31 May. In both analyses, ethnicity was assigned using a name-based classifier. SETTING: Wales (UK). PRIMARY AND SECONDARY OUTCOMES: Admission to an intensive care unit following hospitalisation with a positive SARS-CoV-2 PCR test. Death within 28 days of a positive SARS-CoV-2 PCR test. RESULTS: Using a name-based ethnicity classifier, we found a higher proportion of black, Asian and ethnic minority people tested for SARS-CoV-2 by PCR tested positive, compared with those classified as white. Hospitalised black, Asian and minority ethnic cases were younger (median age 53 compared with 76 years; p<0.01) and more likely to be admitted to intensive care. Bangladeshi (adjusted OR (aOR): 9.80, 95% CI 1.21 to 79.40) and 'white - other than British or Irish' (aOR: 1.99, 95% CI 1.15 to 3.44) ethnic groups were most likely to be admitted to intensive care unit. In Wales, older age (aOR for over 70 years: 10.29, 95% CI 6.78 to 15.64) and male gender (aOR: 1.38, 95% CI 1.19 to 1.59), but not ethnicity, were associated with death in hospitalised patients. CONCLUSIONS: This study adds to the growing evidence that ethnic minorities are disproportionately affected by COVID-19. During the first COVID-19 epidemic wave in Wales, although ethnic minority populations were less likely to be tested and less likely to be hospitalised, those that did attend hospital were younger and more likely to be admitted to intensive care. Primary, secondary and tertiary COVID-19 prevention should target ethnic minority communities in Wales.

RESUMO

BACKGROUND: Infectious intestinal disease (IID), usually presenting as diarrhoea and vomiting, is frequently preventable. Though often mild and self-limiting, its commonness makes IID an important public health problem. In the mid 1990s around 1 in 5 people in England suffered from IID a year, costing around pound0.75 billion. No routine information source describes the UK's current community burden of IID. We present here the methods for a study to determine rates and aetiology of IID in the community, presenting to primary care and recorded in national surveillance statistics. We will also outline methods to determine whether or not incidence has declined since the mid-1990s. METHODS/DESIGN: The Second Study of Infectious Intestinal Disease in the Community (IID2 Study) comprises several separate but related studies. We use two methods to describe IID burden in the community - a retrospective telephone survey of self-reported illness and a prospective, all-age, population-based cohort study with weekly follow-up over a calendar year. Results from the two methods will be compared. To determine IID burden presenting to primary care we perform a prospective study of people presenting to their General Practitioner with symptoms of IID, in which we intervene in clinical and laboratory practice, and an audit of routine clinical and laboratory practice in primary care. We determine aetiology of IID using molecular methods for a wide range of gastrointestinal pathogens, in addition to conventional diagnostic microbiological techniques, and characterise isolates further through reference typing. Finally, we combine all our results to calibrate national surveillance data. DISCUSSION: Researchers disagree about the best method(s) to ascertain disease burden. Our study will allow an evaluation of methods to determine the community burden of IID by comparing the different approaches to estimate IID incidence in its linked components.

RESUMO

BACKGROUND: Campylobacter species is a leading cause of bacterial gastroenteritis worldwide. Quinolone resistance has emerged as an increasing problem among persons with Campylobacter infection over the past decade, but the clinical consequences are unclear. METHODS: A case-comparison study of patients infected with ciprofloxacin-resistant or ciprofloxacin-susceptible Campylobacter species was conducted in Wales during the period 2003-2004. Campylobacter isolates were classified as resistant or susceptible to ciprofloxacin on the basis of standardized disk diffusion methods. Participants were interviewed by telephone at the time of illness, 3 months later, and 6 months later to compare disease severity, duration of illness, and medium-term clinical outcomes. RESULTS: There was no difference between 145 persons with ciprofloxacin-resistant infection and 411 with ciprofloxacin-susceptible infection with regard to the severity or duration of acute illness. Mean duration of diarrhea was similar in patients with ciprofloxacin-resistant versus ciprofloxacin-susceptible infection (8.2 vs. 8.6 days; P = .57) and did not alter significantly after adjustment for potential covariates, including age, underlying disease, foreign travel, use of antidiarrheal medication, and use of antimicrobials in a multiple linear regression model. There was no difference between case patients and comparison patients in the frequency of reported symptoms or in general practitioner consultation rates at either the 3-month or the 6-month follow-up interview. CONCLUSIONS: In this study, there was no evidence of more-severe or prolonged illness in participants with quinolone-resistant Campylobacter infection, nor was there evidence of any adverse medium-term consequences. This suggests that the clinical significance of quinolone resistance in Campylobacter infection may have been overestimated.

RESUMO

OBJECTIVES: To identify risk factors for ciprofloxacin resistance in both travel-related and domestically acquired Campylobacter infection. METHODS: Case-comparison study of patients with ciprofloxacin-resistant and ciprofloxacin-susceptible Campylobacter infection conducted in Wales during 2003 and 2004. RESULTS: Foreign travel was the major risk factor for ciprofloxacin-resistant infection [adjusted odds ratio (adjOR) 24.0, 95% confidence interval (95% CI) 12.6-45.9]. Among travellers, case patients were five times more likely to drink still bottled water (adjOR 4.7, 95% CI 1.0-21.7), whilst among non-travellers, case patients were three times more likely to drink sparkling bottled water (adjOR 3.3, 95% CI 1.5-7.4). There was no increased risk associated with eating poultry or prior quinolone use. CONCLUSIONS: Foreign travel remains the most important risk factor for ciprofloxacin-resistant Campylobacter infection. The possible association of both domestic- and travel-related ciprofloxacin-resistant Campylobacter infection with bottled water needs to be further explored.

RESUMO

BACKGROUND: After some years of a downward trend, antibiotic prescribing rates in the community have tended to level out in many countries. There is also wide variation in antibiotic prescribing between general practices, and between countries. There are still considerable further gains that could be made in reducing inappropriate antibiotic prescribing, but complex interventions are required. Studies to date have generally evaluated the effect of interventions on antibiotic prescribing in a single consultation and pragmatic evaluations that assess maintenance of new skills are rare. This paper describes the protocol for a pragmatic, randomized evaluation of a complex intervention aimed at reducing antibiotic prescribing by primary care clinicians. METHODS AND DESIGN: We developed a Social Learning Theory based, blended learning program (on-line learning, a practice based seminar, and context bound learning) called the STAR Educational Program. The 'why of change' is addressed by providing clinicians in general practice with information on antibiotic resistance in urine samples submitted by their practice and their antibiotic prescribing data, and facilitating a practice-based seminar on the implications of this data. The 'how of change' is addressed through context-bound communication skills training and information on antibiotic indication and choice. This intervention will be evaluated in a trial involving 60 general practices, with general practice as the unit of randomization (clinicians from each practice to either receive the STAR Educational Program or not) and analysis. The primary outcome will be the number of antibiotic items dispensed over one year. An economic and process evaluation will also be conducted. DISCUSSION: This trial will be the first to evaluate the effectiveness of this type of theory-based, blended learning intervention aimed at reducing antibiotic prescribing by primary care clinicians. Novel aspects include feedback of practice level data on antimicrobial resistance and prescribing, use of principles from motivational interviewing, training in enhanced communication skills that incorporates context-bound experience and reflection, and using antibiotic dispensing over one year (as opposed to antibiotic prescribing in a single consultation) as the main outcome. TRIAL REGISTRATION: Current Controlled Trials ISRCTN63355948.

RESUMO

BACKGROUND: Preventing household transmission of Shiga toxin-producing Escherichia coli O157 (STEC O157) infection is important because of the ease of interpersonal transmission and the potential disease severity. METHODS: We conducted a retrospective cohort study of households associated with an outbreak of STEC O157 infection in South Wales, United Kingdom, in autumn 2005. We investigated whether characteristics of the primary case patient or the household were predictors for secondary household transmission of STEC O157 infection. Furthermore, we estimated the proportion of cases that might be prevented by isolation (e.g., hospitalization) of the primary case patient immediately after the microbiological diagnosis and the number of patients with STEC O157 who would need to be isolated to prevent 1 case of hemolytic uremic syndrome. Based on dates of symptom onset, case patients in households were classified as having primary, coprimary, or secondary infection. Secondary cases were considered to be preventable if the secondary case patient's symptoms started >1 incubation period (4 days) after the date of microbiological diagnosis of the primary case. RESULTS: Eighty-nine (91%) of 98 eligible households were enrolled. Among 20 households (22%), 25 secondary cases were ascertained. Thirteen secondary cases (56%) occurred in siblings of the primary case patients; hemolytic uremic syndrome developed in 4 of these siblings. Presence of a sibling (risk ratio, 3.8; 95% confidence interval, 0.99-14.6) and young age (<5 years) of the primary case patient (risk ratio, 2.03; 95% confidence interval, 0.99-41.6) were independent predictors for households in which secondary cases occurred. Of the 15 secondary cases for which complete information was available, 7 (46%) might have been prevented. When restricting isolation to primary case patients who were aged <10 years and who had a sibling, we estimated the number of patients who would need to be isolated to prevent 1 case of hemolytic uremic syndrome to be 47 patients (95% confidence interval, 16-78 patients). CONCLUSIONS: Promptly separating pediatric patients with STEC O157 infection from their young siblings should be considered.

RESUMO

BACKGROUND: Travellers' diarrhoea is the most common health problem among international travellers and much of the burden falls on general practitioners. We assessed whether sentinel surveillance based in primary care could be used to monitor changes in the epidemiology of travellers' diarrhoea. METHODS: A sentinel surveillance scheme of 30 volunteer general practices distributed throughout Wales provides weekly reports of consultations for eight infectious diseases to the national Communicable Disease Surveillance Centre. Travellers' diarrhoea was introduced as a new reportable infection in July 2002. RESULTS: Between 1 July 2002 and 31 March 2005 there were 90 reports of travellers' diarrhoea. The mean annual consultation rate was 15.2 per 100,000 population (95% confidence interval: 12.2-18.7), with the highest rates in summer, in people aged 15-24 years, and in travellers to Southern Europe. A higher proportion of travellers than expected had visited destinations outside Europe and North America when compared to the proportion of all United Kingdom travellers visiting these destinations (38% vs. 11%; Chi2 = 53.3, p < 0.0001). CONCLUSION: Sentinel surveillance has the potential to monitor secular trends in travellers' diarrhoea and to help characterise population groups or travel destinations associated with higher risk.

RESUMO

BACKGROUND: Although influenza immunisation is now recommended for all people aged 65 years and over in the UK, many people in that age group still remain unimmunised. AIM: To investigate lay beliefs about influenza and influenza vaccine in older people to identify appropriate ways of promoting vaccine uptake. DESIGN: Qualitative study using narrative interviews. SETTING: Urban and rural communities in South Wales. METHOD: Participants were 54 people aged 65 years and over who were interviewed in their own home. Of these, 11 were regularly immunised, 18 had consistently refused immunisation (refusers), 15 had defaulted (defaulters), five had never been offered immunisation, and five had recently been immunised for the first time. RESULTS: There was an overwhelming consensus among immunised and unimmunised individuals that they were not at risk from influenza. Even if they did catch influenza, they would not suffer from any serious consequences. Refusers and defaulters were more likely to believe that the influenza vaccine had serious side-effects, while the regularly immunised group were more likely to perceive the vaccine as effective. Multiple prompts from family, friends, or primary care staff were important triggers for receiving immunisation. CONCLUSION: Many older people did not feel vulnerable to influenza, regardless of their age, and this influenced their views on the need for immunisation. Both refusers and defaulters overstated adverse effects from influenza vaccine so this is a potential target for an intervention. Individual prompts, particularly from GPs, seemed to be the most significant motivators to attend for immunisation.

RESUMO

BACKGROUND: Current routine surveillance schemes for sexually transmitted infections (STIs) in the United Kingdom (UK) are not designed for outbreak identification. Recognising STI outbreaks, therefore, depends almost entirely on the alertness of health professionals. The objective of this study was to explore health professionals' knowledge of, and attitudes towards, identification and investigation of STI outbreaks in Wales. METHODS: We conducted a cross-sectional survey in Wales in June 2005, and sent a questionnaire to consultants of genitourinary medicine (GUM, n = 11), a consultant microbiologist from each laboratory (n = 14), all consultants in communicable disease control (n = 5), and to epidemiologists of the National Public Health Service (n = 4). RESULTS: 26 (76%) of 34 survey recipients responded. Of these, 17 (65%) ranked the investigation of STI outbreaks as important or very important, and 19 (73%) perceived participation in the investigation of an STI outbreak as part of their responsibility. Only six (25%) respondents had actively searched their computer system or patient records for a possible STI outbreak in the previous twelve months, and 15 (63%) had never looked for an outbreak. Of seven GUM physicians who said they had identified at least one STI outbreak, three had never informed public health authorities. CONCLUSION: Prompt identification and coordinated investigation of outbreaks, usually through a multidisciplinary outbreak control team, is central to the control of many infectious diseases. This does not appear to be the case for STIs, which we believe represents a lost opportunity to reduce transmission. Besides improved surveillance methods, a change in culture towards STI outbreaks is needed among health professionals in Wales.

RESUMO

OBJECTIVE: To generate estimates of the burden of UK-acquired foodborne disease accounting for uncertainty. DESIGN: A modelling study combining data from national public health surveillance systems for laboratory-confirmed infectious intestinal disease (IID) and outbreaks of foodborne disease and 2 prospective, population-based studies of IID in the community. The underlying data sets covered the time period 1993-2008. We used Monte Carlo simulation and a Bayesian approach, using a systematic review to generate Bayesian priors. We calculated point estimates with 95% credible intervals (CrI). SETTING: UK, 2009. OUTCOME MEASURES: Pathogen-specific estimates of the number of cases, general practice (GP) consultations and hospitalisations for foodborne disease in the UK in 2009. RESULTS: Bayesian approaches gave slightly more conservative estimates of overall health burden (∼511 000 cases vs 566 000 cases). Campylobacter is the most common foodborne pathogen, causing 280 400 (95% CrI 182 503-435 693) food-related cases and 38 860 (95% CrI 27 160-55 610) GP consultations annually. Despite this, there are only around 562 (95% CrI 189-1330) food-related hospital admissions due to Campylobacter, reflecting relatively low disease severity. Salmonella causes the largest number of hospitalisations, an estimated 2490 admissions (95% CrI 607-9631), closely followed by Escherichia coli O157 with 2233 admissions (95% CrI 170-32 159). Other common causes of foodborne disease include Clostridium perfringens, with an estimated 79 570 cases annually (95% CrI 30 700-211 298) and norovirus with 74 100 cases (95% CrI 61 150-89 660). Other viruses and protozoa ranked much lower as causes of foodborne disease. CONCLUSIONS: The 3 models yielded similar estimates of the burden of foodborne illness in the UK and show that continued reductions in Campylobacter, Salmonella, E. coli O157, C. perfringens and norovirus are needed to mitigate the impact of foodborne disease.

RESUMO

The study objective was to investigate self-reported sexual practices among HIV-positive people in Wales in order to estimate the extent of unprotected sex and to develop services that assist positive people reduce the risk of sexual spread of HIV. A cross-sectional postal questionnaire survey was conducted between February and July 1999 at all open-access HIV outpatient facilities in Wales. All HIV-positive people attending during the study period were invited to enroll in the study. Data were obtained on 104/141 (74%) enrolled patients including 70 (67%) homo/bisexual men. Most (79/104, 76%) were sexually active and 42% (33/79) had casual partners. One in six (13/79, 16.5%) sexually active people reported unprotected high-risk sex with HIV-negative or unknown status partners, the majority (9/13, 69%) of whom were male homosexuals. It is important that health professionals specifically address issues of sexual behaviour with HIV positive people during consultation. A renewed safer sex campaign targeting men who have sex with men is urgently needed.

RESUMO

BACKGROUND: Preschool-aged children are the highest consumers of antibiotics, but consult mainly for viral infections. Little is known about how day care, which is common in this age group, influences primary care consulting and treatment-seeking behaviours. AIM: To investigate daycare providers' approaches to excluding and/or readmitting children with infections, and the consequences for parents' consulting and antibiotic-seeking behaviours. DESIGN AND SETTING: Cross-sectional survey, document analysis, and qualitative interviews of daycare providers and parents in South East Wales, UK. METHOD: A total of 328 daycare providers were asked to complete a survey about infection exclusion practices and to provide a copy of their sickness exclusion policy. Next, 52 semi-structured interviews were conducted with purposively selected questionnaire responders and parents using their services. Questionnaire responses underwent bivariate analysis, policies underwent document analysis, and interviews were thematically analysed using constant comparison methods. RESULTS: In total 217 out of 328 (66%) daycare providers responded; 82 out of 199 (41%) reported advising parents that their child may need antibiotics and 199 out of 214 (93%) reported advising general practice consultations. Interviews confirmed that such advice was routine, and beliefs about antibiotic indications often went against clinical guidelines: 24% (n = 136) of sickness exclusion policies mentioning infections made at least one non-evidence-based indication for 'treatment' or antibiotics. Parent interviews revealed that negotiating daycare requirements lowered thresholds for consulting and encouraged antibiotic seeking. CONCLUSION: Daycare providers encourage parents to consult general practice and seek antibiotics through non-evidence-based policies and practices. Parents' perceptions of daycare providers' requirements override their own beliefs of when it is appropriate to consult and seek treatment.
