Hazai kórházi antibiotikum-alkalmazás az elmúlt két évtizedben (1996–2015) | Antibiotic use in the Hungarian hospitals in the last two decades (1996–2015)

Absztrakt Bevezetés: A bakteriális rezisztencia közegészségügyet fenyegető probléma, amely mérsékelhető, lassítható megfelelő antibiotikum-alkalmazással. Célkitűzés: A hazai fekvőbeteg-ellátás szisztémás antibiotikum-felhasználásának bemutatása. Módszer: A kórházi antibiotikum-felhasználási adatokat az Egészségügyi Világszervezet anatómiai-terápiás-kémiai rendszere szerint osztályozták és a Defined Daily Dose metodika szerint kvantifikálták. A standardizálás kórházi betegforgalmi mutatókra, valamint – a nemzetközi összehasonlítás végett – populációra történt. Eredmények: A fekvőbetegszektor antibiotikum-felhasználása az elmúlt 20 évben mennyiségileg kiegyenlített volt (22,4 ± 1,5 DDD/100 ápolási nap), mintázata folyamatos változáson ment keresztül. Megfigyelhettük a parenteralis készítmények alkalmazásának emelkedését (1996-ban 26,4%, 2015-ben 41,6%). Kiemelendő a felhasználás összetételének homogenizálódása az amoxicillin-klavulánsav térnyerése miatt, a fluorokinolon (2,3 vs. 4,2 DDD/100 ápolási nap) és a harmadik generációs cefalosporinfelhasználás (1,0 vs. 2,9 DDD/100 ápolási nap) jelentős emelkedése, valamint a szűk spektrumú penicillinek kiszorulása. Következtetés: A hazai kórházi antibiotikum-felhasználás mennyiségileg alacsony. Ez, illetve a felhasználás mintázatában tapasztalt, nemzetközi mércével is alátámasztott alul- vagy felülreprezentált felhasználás okának és indokoltságának megítélése további vizsgálatot igényel.

Aim: To quantify systemic antibacterial use in Hungarian hospitals. Method: Consumption data were analysed using the Anatomical-Therapeutic-Chemical – Defined Daily Dose (ATC/DDD) methodology. Data were standardized for patient turnover and also for population to enable international benchmarking. Results: Hospital antibiotic use was quite constant (22.4 ± 1.5 DDD/100 patient-days), but its composition changed substantially. The use of parenteral products rose gradually (in 1996 26.4% and in 2015 41.6%). The pattern of use was homogenised due to the headway of co-amoxiclav use. A substantial increase of fluoroquinolone (2.3 vs. 4.2 DDD/100 patient-days) and third generation cephalosporin (1.0 vs. 2.9 DDD/100 patient-days) use was detected. In parallel the use of narrow spectra penicillins diminished. Conclusion: Hungarian hospital antibiotic use is low. The causes and the justification of this low use together with the internationally outstanding use of certain antibacterials should be addressed in future studies. Orv.

Spontaneous Ventilation Combined with Double-Lumen Tube Intubation during Thoracic Surgery: A New Anesthesiologic Method Based on 141 Cases over Three Years

Background: Non-intubated thoracic surgery has not achieved widespread acceptance despite its potential to improve postoperative outcomes. To ensure airway safety, our institute has developed a technique combining spontaneous ventilation with double-lumen tube intubation (SVI). This study aimed to verify the feasibility and limitations of this SVI technique. Methods: For the SVI method, anesthesia induction involves fentanyl and propofol target-controlled infusion, with mivacurium administration. Bispectral index monitoring was used to ensure the optimal depth of anesthesia. Short-term muscle relaxation facilitated double-lumen tube intubation and early surgical steps. Chest opening preceded local infiltration, followed by a vagal nerve blockade to prevent the cough reflex and a paravertebral blockade for pain relief. Subsequently, the muscle relaxant was ceased. The patient underwent spontaneous breathing without coughing during surgical manipulation. Results: Between 10 March 2020 and 28 October 2022, 141 SVI surgeries were performed. Spontaneous respiration with positive end-expiratory pressure was sufficient in 65.96% (93/141) of cases, whereas 31.21% (44/141) required pressure support ventilation. Only 2.84% (4/141) of cases reversed to conventional anesthetic management, owing to technical or surgical difficulties. Results of the 141 cases: The mean maximal carbon dioxide pressure was 59.01 (34.4–92.9) mmHg, and the mean lowest oxygen saturation was 93.96% (81–100%). The mean one-lung, mechanical and spontaneous one-lung ventilation time was 74.88 (20–140), 17.55 (0–115) and 57.73 (0–130) min, respectively. Conclusions: Spontaneous ventilation with double-lumen tube intubation is safe and feasible for thoracic surgery. The mechanical one-lung ventilation time was reduced by 76.5%, and the rate of anesthetic conversion to relaxation was low (2.8%)

Impact of Guideline Adherence on Outcomes in Patients Hospitalized with Community‐Acquired Pneumonia (CAP) in Hungary: A Retrospective Observational Study

Community‐acquired pneumonia (CAP) is a leading cause of morbidity and mortality worldwide. This retrospective observational study evaluated the antibiotic prescription patterns and associations between guideline adherence and outcomes in patients hospitalized with CAP in Hungary. Main outcome measures were adherence to national and international CAP guidelines (agent choice, dose) when using empirical antibiotics, antibiotic exposure, and clinical outcomes. Demographic and clinical characteristics of patients with CAP in the 30‐day mortality and 30‐day survival groups were compared. Fisher’s exact test and t‐test were applied to compare categorical and continuous variables, respectively. Adherence to the national CAP guideline for initial empirical therapies was 30.61% (45/147) for agent choice and 88.89% (40/45) for dose. Average duration of antibiotic therapy for CAP was 7.13 ± 4.37 (mean ± SD) days, while average antibiotic consumption was 11.41 ± 8.59 DDD/patient (range 1–44.5). Adherence to national guideline led to a slightly lower 30‐day mortality rate than guideline non‐adherence (15.56% vs. 16.67%, p > 0.05). In patients aged ≥ 85 years, 30‐day mortality was 3 times higher than in those aged 65–84 years (30.43% vs. 11.11%). A significant difference was found between 30‐day non‐survivors and 30‐day survivors regarding the average CRP values on admission (177.28 ± 118.94 vs. 112.88 ± 93.47 mg/L, respectively, p = 0.006) and CCI score (5.71 ± 1.85 and 4.67 ± 1.83, p = 0.012). We found poor adherence to the national and international CAP guidelines in terms of agent choice. In addition, high CRP values on admission were markedly associated with higher mortality in CAP. © 2022 by the authors. Licensee MDPI, Basel, Switzerland.

Analysing the trend over time of antibiotic consumption in the community

This tutorial describes and illustrates statistical methods to detect time trends possibly including abrupt changes (referred to as change-points) in the consumption of antibiotics in the community.For the period 1997-2017, data on consumption of antibacterials for systemic use (ATC group J01) in the community, aggregated at the level of the active substance, were collected using the WHO ATC/DDD methodology and expressed in DDD (ATC/DDD index 2019) per 1000 inhabitants per day. Trends over time and presence of common change-points were studied through a set of non-linear mixed models.After a thorough description of the set of models used to assess the time trend and presence of common change-points herein, the methodology was applied to the consumption of antibacterials for systemic use (ATC J01) in 25 EU/European Economic Area (EEA) countries. The best fit was obtained for a model including two change-points: one in the first quarter of 2004 and one in the last quarter of 2008.Allowing for the inclusion of common change-points improved model fit. Individual countries investigating changes in their antibiotic consumption pattern can use this tutorial to analyse their country data

Hospital Antibiotic Consumption before and during the COVID-19 Pandemic in Hungary

The aim of this study was to assess antibiotic use in the Hungarian hospital care sector during and before the pandemic. Aggregated systemic antibiotic (ATC: J01) utilisation data were obtained for the 2010–2021 period. Classifications and calculations were performed according to the WHO ATC/DDD index and expressed as DDD per 1000 inhabitants and per day (DID), DDD per 100 patient-days (DHPD) and DDD/discharge. A linear regression (trend analysis) was performed for the pre-COVID years (2010–2019) and a prediction interval was set up to assess whether the pandemic years’ observed utilisation fit in. Antibiotic utilisation was constant in DID before and during the pandemic (2019: 1.16; 2020: 1.21), while we observed a substantial increase in antibiotic use when expressed in DDD per 100 patient-days (2019: 23.3, 2020: 32.2) or DDD/discharge (2019: 1.83, 2020: 2.45). The observed utilisation level of penicillin combinations; first-, third- and fourth-generation cephalosporins; carbapenems; glycopeptides; nitroimidazoles and macrolides exceeded the predicted utilisation values in both pandemic years. Before the pandemic, co-amoxiclav headed the top list of antibiotic use, while during the pandemic, ceftriaxone became the most widely used antibiotic. Azithromycin moved up substantially on the top list of antibiotic use, with a 397% increase (2019: 0.45; 2020: 2.24 DHPD) in use. In summary, the pandemic had a major impact on the scale and pattern of hospital antibiotic use in Hungary

Impact of the COVID-19 Pandemic on Ambulatory Care Antibiotic Use in Hungary: A Population-Based Observational Study

The COVID-19 pandemic and related restrictions have potentially impacted the use of antibiotics. We aimed to analyze the use of systemic antibiotics (J01) in ambulatory care in Hungary during two pandemic years, to compare it with pre-COVID levels (January 2015–December 2019), and to describe trends based on monthly utilization. Our main findings were that during the studied COVID-19 pandemic period, compared to the pre-COVID level, an impressive 23.22% decrease in the use of systemic antibiotics was detected in ambulatory care. A significant reduction was shown in the use of several antibacterial subgroups, such as beta-lactam antibacterials, penicillins (J01C, −26.3%), and quinolones (J01M, −36.5%). The trends of antibiotic use moved in parallel with the introduction or revoking of restriction measures with a nadir in May 2020, which corresponded to a 55.46% decrease in use compared to the previous (pre-COVID) year’s monthly means. In general, the systemic antibiotic use (J01) was lower compared to the pre-COVID periods’ monthly means in almost every studied pandemic month, except for three months from September to November in 2021. The seasonal variation of antibiotic use also diminished. Active agent level analysis revealed an excessive use of azithromycin, even after evidence of ineffectiveness for COVID-19 emerged
