RESUMO

BACKGROUND: Several changes have led to general practitioners (GPs) working in a more differentiated setting today and being supported by other health professions. As practice changes, primary care specific continuing medical education (CME) may also need to adapt. By comparing different primary care specific CME approaches for GPs across Europe, we aim at identifying challenges and opportunities for future development. METHODS: Narrative review assessing, analysing and comparing CME programs for general practitioners across different north-western European countries (UK, Norway, the Netherlands, Belgium (Flanders), Germany, Switzerland, and France). Templates containing detailed items across seven dimensions of country-specific CME were developed and used. These dimensions are role of primary care within the health system, legal regulations regarding CME, published aims of CME, actual content of CME, operationalisation, funding and sponsorship, and evaluation. RESULTS: General practice specific CME in the countries under consideration are presented and comparatively analysed based on the dimensions defined in advance. This shows that each of the countries examined has different strengths and weaknesses. A clear pioneer cannot be identified. Nevertheless, numerous impulses for optimising future GP training systems can be derived from the examples presented. CONCLUSIONS: Independent of country specific CME programs several fields of potential action were identified: the development of curriculum objectives for GPs, the promotion of innovative teaching and learning formats, the use of synergies in specialist GP training and CME, the creation of accessible yet comprehensive learning platforms, the establishment of clear rules for sponsorship, the development of new financing models, the promotion of fair competition between CME providers, and scientifically based evaluation.

RESUMO

OBJECTIVE: To determine the needs of primary healthcare general practice (GP) staff, stakeholders and trainers to inform the adaptation of a locally successful complex intervention (Chlamydia Intervention Randomised Trial (CIRT)) aimed at increasing chlamydia testing within primary healthcare within South West England to three EU countries (Estonia, France and Sweden) and throughout England. DESIGN: Qualitative interviews. SETTING: European primary healthcare in England, France, Sweden and Estonia with a range of chlamydia screening provision in 2013. PARTICIPANTS: 45 GP staff, 13 trainers and 18 stakeholders. INTERVIEWS: The iterative interview schedule explored participants' personal attitudes, subjective norms and perceived behavioural controls around provision of chlamydia testing, sexual health services and training in general practice. Researchers used a common thematic analysis. RESULTS: Findings were similar across all countries. Most participants agreed that chlamydia testing and sexual health services should be offered in general practice. There was no culture of GP staff routinely offering opportunistic chlamydia testing or sexual health advice, and due to other priorities, participants reported this would be challenging. All participants indicated that the CIRT workshop covering chlamydia testing and sexual health would be useful if practice based, included all practice staff and action planning, and was adequately resourced. Participants suggested minor adaptations to CIRT to suit their country's health services. CONCLUSIONS: A common complex intervention can be adapted for use across Europe, despite varied sexual health provision. The intervention (ChlamydiA Testing Training in Europe (CATTE)) should comprise: a staff workshop covering sexual health and chlamydia testing rates and procedures, action planning and patient materials and staff reminders via computer prompts, emails or newsletters, with testing feedback through practice champions. CATTE materials are available at: www.STItraining.eu.

RESUMO

PURPOSE: Few in vivo studies have been reported describing efficacy and duration of antibiotic lock therapy (ALT) with daptomycin (DPT) for long-term catheter-related bloodstream infections (CRBSI) due to coagulase-negative staphylococci (CoNS). We retrospectively analysed the efficacy of short-course ALT with DPT in combination with systemic treatment (ST) for CoNS-associated CRBSI in our hospital. METHODS: Patients admitted for CoNS-associated CRBSI and treated with DPT as ALT and ST were retrospectively analysed. Success was defined as preservation of the catheter device 30 days after ending treatment. Catheter removal within 30 days of discontinuing treatment, for either microbiological documentation of CRBSI relapse or re-occurrence of unexplained fever, was considered as failure. RESULTS: Among 7610 patients admitted to the Departments of Internal Medicine/Infectious Diseases and Pneumology in Cannes from January 2013 to November 2015, we identified 28 episodes of CoNS-associated CRBSI. Seven patients died of cancer during follow-up. Thus, 21 episodes were analysed among 20 patients (median age 67 years, 12 males, all treated for neoplasia and carrying a port-a-cath® device). Staphylococcus epidermidis was the main agent responsible for CRBSI. Median duration of systemic and ALT DPT was 3 days, in combination with rifampin for 4 days and then generally followed by a switch to oral drugs, most frequently cotrimoxazole or linezolid, to achieve 14 median days of treatment. Clinical success and failure rates were 76% and 24%, respectively. CONCLUSIONS: Short-course DPT as ALT, combined with 14 days of ST, allowed conservative management of CoNS-associated CRBSI in surgically implanted-catheters in three-fourth of cases.

RESUMO

Background: Lower urogenital tract Chlamydia trachomatis (Ct) infection is the most common bacterial sexually transmitted infection in Europe, especially among young people with multiple partners. Often asymptomatic, its spread and severity are due to delayed diagnosis, highlighting the need for early detection.Objective: Implementation and evaluation of a complex intervention targeting GPs in the Alpes-Maritimes (06) promoting opportunistic screening of Ct infection in young patients.Method: Academic detailing visits provided 105 randomized GPs with tools and patient self-testing kits to include 10 patients over a 6-month period followed by a quantitative (prescribed screenings / reimbursed screenings among visited GPs and all GPs in the Alpes-Maritimes compared to the previous year) and a qualitative assessment (post-interventional interviews with GPs and trainers).Results: In the context of a global increase in screening between the 2013 and 2014 seasons (+15%), the intervention resulted in a significantly higher rate (73%), p = 0.02. Screening was performed in 73 (48%) patients and 12 were PCR-positive. Qualitative analysis of post-interventional interviews with GPs and a focus group of AD visitors highlighted facilitating factors and obstacles to screening. Conclusion: Our intervention, appreciated by the visited GPs, demonstrates its potential impact and feasibility in primary care. GPs used facilitating factors to overcome the identified obstacles. To sustain this intervention, evaluated tools will be available on line to help GPs promote Ct screening as well as for sexual health training targeting GPs.

RESUMO

We describe a case of skin rash and bilateral uveitis secondary to Rickettsia conorii infection. A 60-year-old female patient, living in the rural hinterland of Cannes, was referred to our hospital in mid-August 2012 for skin rash, fever, and arthromyalgia. Blood tests showed increased inflammatory markers, hepatic cytolysis and anicteric cholestasis. Ophthalmic examination revealed bilateral papillitis and focal chorio-retinitis. Fluoroscopic angiography demonstrated early hypofluorescence, with a few arteriolar occlusions, and subsequent hyperfluorescence and focal vasculitis. R. conorii antibodies were identified by immunofluorescence antibody test. Investigation of other infective agents and the immunological panel were negative. A 2-week course of doxycycline 200 mg/day was prescribed, and fever rapidly subsided, the skin rash resolved and vision improved. Ophthalmic examination a month and a half later showed almost all retinal lesions had disappeared and inflammation markers had returned to normal.

RESUMO

AIM: To evaluate virological response to telaprevir or boceprevir in combination with pegylated interferon and ribavirin and resistance mutations to NS3/4A inhibitors in hepatitis C virus-human immunodeficiency virus (HCV-HIV) coinfected patients in a real life setting. METHODS: Patients with HCV genotype 1-HIV coinfection followed in Nice University Hospital internal medicine and infectious diseases departments who initiated treatment including pegylated interferon and ribavirin (PegIFN/RBV) + telaprevir or boceprevir, according to standard treatment protocols, between August 2011 and October 2013 entered this observational study. Patient data were extracted from an electronic database (Nadis(®)). Liver fibrosis was measured by elastometry (Fibroscan(®)) with the following cut-off values: F0-F1: < 7.1 kPa, F2: 7.1-9.5 kPa, F3: 9.5-14.5 kPa, F4: ≥ 14.5 kPa. The proportion of patients with sustained virological response (SVR) twelve weeks after completing treatment, frequency and type of adverse events, and NS3/4A protease inhibitor mutations were described. RESULTS: Forty-one patients were included: 13 (31.7%) patients were HCV-treatment naïve, 22 (53.7%) had advanced liver fibrosis or cirrhosis (Fibroscan stage F3 and F4); none had decompensated cirrhosis or hepatocellular carcinoma; all were receiving antiretroviral treatment, consisting for most them (83%) in either a nucleoside reverse-transcriptase inhibitor/protease inhibitor or/integrase inhibitor combination; all patients had undetectable HIV-RNA. One patient was lost to follow-up. SVR was achieved by 52.5% of patients. Five patients experienced virological failure during treatment and four relapsed. Seven discontinued treatment due to adverse events. Main adverse events included severe anemia (88%) and rash (25%). NS3/4A protease mutations were analyzed at baseline and at the time of virological failure in the 9 patients experiencing non-response, breakthrough or relapse. No baseline resistance mutation could predict resistance to HCV protease inhibitor-based treatment. CONCLUSION: Telaprevir and boceprevir retain their place among potential treatment strategies in HIV-HCV coinfected patients including those with advanced compensated liver disease and who failed previous PegIFN/RBV therapy.

RESUMO

BACKGROUND: Cancer incidence and prevalence estimates are necessary to inform health policy, to predict public health impact and to identify etiological factors. Registers have been used to estimate the number of cancer cases. To be reliable and useful, cancer registry data should be complete. Capture-recapture is a method for estimating the number of cases missed, originally developed in ecology to estimate the size of animal populations. Capture recapture methods in cancer epidemiology involve modelling the overlap between lists of individuals using log-linear models. These models rely on assumption of independence of sources and equal catchability between individuals, unlikely to be satisfied in cancer population as severe cases are more likely to be captured than simple cases. METHODS: To estimate cancer population and completeness of cancer registry, we applied M(th) models that rely on parameters that influence capture as time of capture (t) and individual heterogeneity (h) and compared results to the ones obtained with classical log-linear models and sample coverage approach. For three sources collecting breast and colorectal cancer cases (Histopathological cancer registry, hospital Multidisciplinary Team Meetings, and cancer screening programmes), individual heterogeneity is suspected in cancer population due to age, gender, screening history or presence of metastases. Individual heterogeneity is hardly analysed as classical log-linear models usually pool it with between-"list" dependence. We applied Bayesian Model Averaging which can be applied with small sample without asymptotic assumption, contrary to the maximum likelihood estimate procedure. RESULTS: Cancer population estimates were based on the results of the M(h) model, with an averaged estimate of 803 cases of breast cancer and 521 cases of colorectal cancer. In the log-linear model, estimates were of 791 cases of breast cancer and 527 cases of colorectal cancer according to the retained models (729 and 481 histological cases, respectively). CONCLUSIONS: We applied M(th) models and Bayesian population estimation to small sample of a cancer population. Advantage of M(th) models applied to cancer datasets, is the ability to explore individual factors associated with capture heterogeneity, as equal capture probability assumption is unlikely. M(th) models and Bayesian population estimation are well-suited for capture-recapture in a heterogeneous cancer population.

RESUMO

Regular surveys of pneumococcal nasopharyngeal carriage have been conducted among children attending daycare centers in Southeastern France from 1999 to 2012. We compared carriage rate, susceptibility patterns and serotype distribution in 2012, following implementation of the 13-valent pneumococcal conjugate vaccine, with findings from 5 previous surveys. Carriage rate was stable, antibiotic susceptibility improved and only serotype 19A persisted among vaccine-types.

RESUMO

PURPOSE: Antimicrobial lock therapy (ALT) seems a promising approach for treatment of central line associated bloodstream infections (CLABSI). The recent introduction of molecules such as daptomycin and tigecycline, alone or in combination with other molecules, improved chances of efficacy of ALT, due to their activity on the bacterial biofilm. Our aim was to review the literature concerning ALT for CLABSI, including data concerning novel molecules. METHODS: We included case-control studies evaluating two or more molecules as ALT in central venous catheter infections extracted from the Medline database. Among 221 available articles in Pubmed, 54 were selected for their particular interest concerning ALT. RESULTS: Incidence of CLABSI is high worldwide. Mechanisms of catheter infection include contamination by skin bacteria, hand contamination and hematogenous diffusion. Catheter-infection is associated with biofilm formation, which reduces the efficacy of ALT. The most promising situation for ALT to succeed in salvaging a catheter appears to be coagulase-negative Staphylococcus infection, which is the main causative agent of CLABSI. Daptomycin, Tigecycline, Ethanol and Taurolidine appear as the best options for treating CLABSI; data are mostly available for Daptomycin, which showed, alone or associated with Rifampin, good in vitro potency on biofilm, but few in vivo data exist on efficacy. CONCLUSIONS: The introduction of novel molecules has increased chances of catheter salvage with ALT in case of CLABSI, but further in vivo studies are needed.

RESUMO

BACKGROUND: The objectives of this study were to describe and compare chlamydia testing provided by general practitioners (GPs) in four selected European countries with well-developed primary health care systems and high reported chlamydia rates; we aimed to compare contrasting countries where chlamydia testing is provided by GPs (England, Sweden) with countries where primary care chlamydia testing is absent or very limited (France, Estonia). METHODS: For data generation a structured questionnaire was developed and secondary data sources were searched. The questionnaire developed by the research team allowed a systematic approach to analysing chlamydia care (including testing in general practice) and the gathering of relevant data. RESULTS: There were no significant differences in the burden of the disease or the type of general practice care provision in the study countries. In all four countries, testing for chlamydia (with nucleic acid amplification test, NAAT) is available in the public sector, a substantial proportion (>60%) of young people aged 16-25 years visit their general practitioner (GP) annually, and reimbursement for chlamydia testing costs to the relevant parties (GPs in England, Sweden and Estonia; and patients in France) by the national health insurance system or its equivalent.In countries where chlamydia testing is provided by GPs (England, Sweden) a national strategy or plan on STI control that specifically mentions chlamydia was in force, chlamydia care guidelines for GPs were in place and STI management was more firmly established in the GP residency training curriculum, either formally (England) or informally (Sweden), than in the other countries. CONCLUSION: Future research on the effectiveness of chlamydia screening (also in the context of general practice care) and program provision should reflect national needs and the prevention of complications.

RESUMO

OBJECTIVE: To assess changes over time in neuropsychological test results (NPr) and risk factors among a regularly followed HIV-infected patient population. METHODS: Prospective cohort of HIV-infected patients randomly selected to undergo neuropsychological follow-up. Test score was adjusted for age, sex and education. Patients were divided into five groups: normal tests, neuropsychological deficit (one impaired cognitive domain), asymptomatic neurocognitive disorders (ANIs), mild neurocognitive disorders (MNDs) and HIV-associated dementia (HAD). Demographic and background parameters including CSF drug concentration penetration effectiveness (CPE) score 2010 were recorded. Changes in NPr and associated risk factors were analyzed. RESULTS: Two hundred and fifty-six patients underwent neuropsychological tests and 96 accepted follow-up approximately 2 years later. The groups were comparable. Upon neuropsychological retesting, six patients improved, 31 worsened and 59 were stable. The proportion of patients with HIV-associated neurocognitive disorders (HANDs) rose from 26 to 45%, with ANIs and MNDs still mostly represented. Most patients initially diagnosed with HANDs remained stable, five of 25 showed clinical improvement and three of 25 deteriorated. Of 33 patients with normal tests, four deteriorated, whereas 24 of 38 with initial neuropsychological deficit had poorer NPr, and contributed most of the new HAND cases. Patients with clinical deterioration had a lower CPE score both at inclusion (6.9 vs. 8.1; P = 0.005) and at the end of follow-up (7.2 vs. 7.8; P = 0.08) than those with improved or stable performance. This was confirmed by multivariate analysis. CONCLUSION: Patients with higher CPE scores upon inclusion and at the end of follow-up were at lower risk of clinical worsening, suggesting that combination antiretroviral therapy with better CSF penetration could protect against cognitive deterioration.

RESUMO

OBJECTIVES: Determining the prevalence of children in day-care centres (DCCs) carrying faecal extended-spectrum ß-lactamase (ESBL)-producing Enterobacteriaceae and molecularly characterizing those belonging to the Escherichia coli species. METHODS: Stools were collected from children's diapers (January-April 2012) in randomly chosen DCCs and plated onto ChromID ESBL. Colonies growing on this medium were identified by the Vitek 2 system and tested for antibiotic susceptibility and for ESBL production by the double-disc synergy test. ESBL genotypes were determined as well as phylogenetic groups, ERIC-2 (enterobacterial repetitive intergenic consensus) PCR profiles and sequence types (STs) for the E. coli isolates. Serotypes, virotypes, fimH alleles, ESBL-carrying plasmids and PFGE patterns were determined for the ST131 E. coli isolates. RESULTS: Among 419 children from 25 participating DCCs, 1 was colonized by CTX-M-15-producing Klebsiella pneumoniae and 27 (6.4%) by E. coli, which all produced CTX-M enzymes [CTX-M-15 (37%), CTX-M-1 (26%), CTX-M-14 (22%), CTX-M-27 (11%) and CTX-M-22 (4%)]. The 27 E. coli isolates, 55.5% belonging to group B2, displayed 20 ERIC-2 PCR profiles and 16 STs. The ST131 E. coli isolates were dominant (44%), displayed serotypes O25b:H4 and O16:H5, fimH alleles 30 and 41 and virotypes A and C. According to the PFGE patterns, one strain of E. coli ST131 producing a CTX-M-15 enzyme carried by an IncF F2:A1:B- plasmid had spread within one DCC. CONCLUSIONS: This study shows a notable prevalence (6.4%) of DCC children with faecal CTX-M-producing E. coli isolates comprising a high proportion of E. coli ST131 isolates, suggesting that these children might be a reservoir of this clone.

RESUMO

Contributory factors to HIV-associated neurocognitive disorders (HAND) have been shown to include age, co-morbid infections, medication toxicity, virological, genetic and vascular mechanisms, as well as microbial translocation of lipopolysaccharide (LPS), which is suspected to trigger monocyte activation and increase trafficking of infected cells into the brain. In this study, our aim was to assess the degree of neurocognitive impairment in a group of randomly selected HIV-infected patients and investigate potential risk factors, including LPS plasma levels. Furthermore, we evaluated the relevance of LPS as a potential marker for screening patients with mild neurocognitive impairment. LPS plasma levels were compared among patients with HAND and those with no HAND. As LPS has also been shown to be elevated in hepatitis C co-infection, the analysis was stratified according to the presence or not of hepatitis C virus (HCV) co-infection. Differences between groups were evaluated using chi-square tests and Kruskal-Wallis non-parametric tests. Stepwise logistic regression was performed to identify independent risk factors for HAND in the subgroups of HCV-positive and negative patients. A p value <0.05 was considered significant. Analyses were conducted using SPSS® software. From December 2007 to July 2009, 179 patients were tested (mean age 44, 73 % male, 87 % on treatment, 30 % HCV co-infected, median CD4 504/ml and 67 % with viral load below 40 copies/ml). HAND was identified in 40/179 patients (22 %), the majority displaying asymptomatic neurocognitive impairment or mild neurocognitive disorder. Univariate analysis showed that age, illicit drug use, hepatitis C co-infection, prior AIDS-defining events, CD4/CD8 ratio and LPS plasma levels were significantly associated with HAND. The median LPS level was 98.2 pg/ml in the non-HAND group versus 116.1 pg/ml in the HAND group (p < 0.014). No differences were found in LPS values between subgroups of impairment. There was a clear association between LPS levels and HAND in the HCV-positive group (p = 0.036), while there was none in the HCV-negative group (p = 0.502). No difference in degree of hepatic fibrosis was found between the HAND and non-HAND groups. In conclusion, LPS levels were associated with HAND in the HCV-positive group, while, in the HCV-negative group, age and pro-viral DNA were the only variables independently associated with HAND. There was no difference in degree of liver disease as predicted by score of fibrosis between HAND and non-HAND groups. The role of HCV co-infection and higher LPS levels in the pathogenesis of HAND in patients with viral suppression on treatment requires further investigation.

RESUMO

INTRODUCTION: Cancer population studies require reliable and complete baseline data, which should theoretically be available by collecting histopathology records. The completeness of such a collection was evaluated using capture-recapture analysis based on three data sources concerning breast and colorectal cancers over an identical period and within the same geographical area. METHOD: The total number of breast and colon cancer cases was estimated using capture-recapture analysis based on the number of cases which were common or not between sources recording screened, diagnosed and treated cancers in the French Alpes Maritimes district. RESULT: The estimated total number of new cases of breast cancer diagnosed among Alpes Maritimes residents women aged 50-75 was 791 (95% CI: 784-797) in 2008. Of these 791 cases, 729 were identified through histopathology records, thus amounting to 92.2% completeness (95% CI: 91.5-93.0%). The total estimated number of new cases of colorectal cancer diagnosed among Alpes Maritimes residents aged 50-75 was 527 (95% CI: 517-536). Of these 527 cases, 481 were identified through histopathology records, thus amounting to 91.3% completeness (95% CI: 89.7-93.0%). CONCLUSION: The estimated completeness of cancer records collected from histopathology laboratories was higher than 90% for new cases of breast and colorectal cancer within the age range concerned by the screening programme. A verified and validated histopathology data collection may be useful for cancer population studies.

RESUMO

OBJECTIVE: Trends in antibiotic prescriptions among children attending day-care centres (DCCs) were studied before and after campaigns promoting prudent antibiotic use and the introduction of pneumococcal conjugate vaccine. DESIGN AND SETTING: Cross-sectional studies were conducted on a two-stage cluster sample of children aged 3 months to 4 years attending DCCs the Alpes Maritimes in France between January and March in 1999, 2004 and 2008. Antibiotic treatments given in the previous 3 months and their indications were studied. INTERVENTIONS: A local public health intervention promoting prudent paediatric antibiotic prescriptions was implemented in 2000 and followed by a nationwide campaign in 2002. MAIN OUTCOME MEASURES: Trends in the number and type of antibiotic prescriptions, and indications for antibiotic use, over the study period. RESULTS: 217, 254 and 279 children provided information in 1999, 2004 and 2008, respectively. The proportion of children who had received antibiotics within the previous 3 months fell from 58.5% (95% CI 51.7% to 65.2%) in 1999 to 29.7% (95% CI 24.4 to 35.5) in 2008. The number of treated episodes/child dropped from 0.99±1.14 to 0.35±1.16 (p<0.00001). Otitis media accounted for an increasing percentage of antibiotic use, rising from 35.3% (95% CI 29.0% to 42.2%) to 56.0% (95% CI 46.3% to 66.6%). Prescriptions for third-generation cephalosporins increased from 26.0% (95% CI 20.4% to 32.5%) to 49.5% (95% CI 39.2% to 59.7%). CONCLUSIONS: Paediatric antibiotic prescriptions dropped significantly following campaigns and the introduction of pneumococcal immunisation in France. Improvements are still needed regarding indications and choice of compounds.

RESUMO

The high rates of antibiotic prescriptions and antimicrobial resistance in France motivated its participation in the European e-Bug school project concerning microbes, and infection transmission, prevention and treatment. The prospect of raising awareness among children, helping them to adopt suitable attitudes and behaviour towards infection transmission and treatment starting from childhood, generated enthusiastic support from relevant national educational and health institutions throughout the Project. France was actively involved in every stage: background research showed that the subject matter was best suited to the national science curricula of the fourth and fifth forms in junior schools, and the sixth and ninth forms in senior schools; a focus group study with junior and senior teachers elicited teachers' needs concerning teaching resources; and a qualitative and quantitative evaluation, after translation and pack review, enabled further adaptation of the packs. This evaluation showed an overall enthusiastic reception by teachers and their students in France, and reassured teachers on the ease of use of the Project's resources and students' progress. The e-Bug Project was launched through a national institutional implementation plan in September 2009 and orders for e-Bug tools increased rapidly. By the end of October, 57% of all senior science teachers and 16% of all junior school teachers had ordered the pack. France is one of the most frequent users of the e-Bug web site. The collaboration with both educational and health partners was particularly helpful to implementing the Project, and this was confirmed by the favourable reception and participation of teachers and students in the field.

RESUMO

A 52-year-old woman with a history of Crohn's disease was admitted due to peritonitis which followed an intestinal perforation. After transitory treatment with voriconazole, resolution of the infection was complicated by recurring peritonitis resulting from necrosis and perforation of the left colon which ultimately lead to the death of the patient. Microscopic examination of the peritoneal fluid revealed the presence of broad, irregular hyphae and culture of the fluid yielded Rhizopus microsporus. The identification of the fungus was confirmed by its characteristic microscopic morphology and sequencing of the ITS region of the rDNA. The histopathologic examination of the colon tissue demonstrated the presence of broad, non-septate hyphae and the same fungus was again isolated in culture.

RESUMO

Pneumococcal nasopharyngeal carriage, serotype distribution, and penicillin-susceptibility were monitored among children attending daycare centers in France from 1999 to 2006 to assess the impact of pneumococcal conjugate vaccine and antibiotic-reducing policies. Pneumococcal carriage remained stable. Immunization rates reached 68% in 2006. Serotype distribution shifted significantly from vaccine serotypes to vaccine-related and nonvaccine serotypes. Antibiotic treatments fell by 50%.
