Nurses' attitudes, behaviours, and enablers of intravenous to oral switching (IVOS) of antibiotics: A mixed-methods survey of nursing staff in secondary care hospitals across the Midlands region of England

BACKGROUND

Intravenous (IV) antibiotic use in secondary care in England is widespread. Timely appropriate intravenous to oral switch (IVOS) has the potential to deliver significant clinical and operational benefits. To date, antimicrobial stewardship (AMS) efforts around IVOS have not focused on the nursing staff who administer antibiotics, which represents a significant gap in AMS programmes.

AIMS

To determine the involvement of bedside nurses in acute trusts in the Midlands region of England in IVOS in their organisations and describe their views regarding how to improve IVOS.

METHODS

An anonymous self-administered mixed-methods online survey was developed and distributed to nursing staff in acute trusts via antimicrobial stewardship networks between March and May 2023. Quantitative data was analysed to describe participant demographics and behaviours, whereas barriers and enablers to IVOS were explored through thematic content analysis of responses to open-ended questions.

FINDINGS

545 nursing staff responded to the survey. The majority (65.3%) routinely suggested IVOS to clinicians, despite only 50.6% being aware of local IVOS policies. One third (34.7%) did not suggest IVOS, relying on doctors, believing their patients needed IV treatment, or lacked knowledge and skills to request IVOS. Content analysis of suggestions for improving the rate of IVOS proposed three major themes (People, Process, System) and identified that education and training, improved confidence and interprofessional relationships, and prompts were important drivers.

CONCLUSIONS

Nursing staff suggest IVOS to other clinicians, but more education and resources are needed to enable and empower them in this role.

Saving time when preparing intravenous antibiotics

Preparation of intravenous antibiotic doses takes up a significant amount of nurse time and exposes nurses to the risk of needlestick injury. The use of the Ecoflac® Connect needle-free connector could streamline preparation, reducing the time taken as well as eliminating needlestick injury risk. Because Ecoflac Connect is a closed system, it also minimises the risk of microbial contamination. This study showed that it took 83 experienced nurses 73.6 (SD 25.0) seconds to prepare an amoxicillin injection using the Ecoflac Connect needle-free connector compared with 110.0 (SD 34.6) seconds using the standard needle and syringe method, saving 36 seconds per dose on average, reducing the time taken by one-third. Based on recent government figures, the saving in nurse time would equate to 200-300 full-time nurses in England, equivalent to £6.15 million-£9.23 million a year. Additional savings would accrue from the prevention of needlestick injuries. Where wards are understaffed, this time saving could be critical, increasing time for care.

Intravenous antibiotic therapy after laparoscopic appendectomy in acute complicated appendicitis: the patient clinical response is the key

INTRODUCTION

The guidelines about acute complicated appendicitis (ACA) recommend 3-5 days of postoperative intravenous antibiotics (IVA). Nevertheless, the time selected by the surgeon can vary according to patient clinical response, ACA type, and professional experience. Once an adequate clinical response is obtained, the change from IVA to oral antibiotic (OA) could be realized without the waiting time established with satisfactory results.

OBJECTIVE

Determine if a short course of IVA and/or switch to oral route is safe based on the patient clinical response.

MATERIALS AND METHODS

Observational prospective cohort study from a general surgery reference center database since July 2019.

RESULTS AND CONCLUSION

48 patients with ACA intraoperative findings were included. Regarding postoperative antibiotic management, only preoperative IVA: 7 (14.58%), IVA 1-3 days: 1 (20.83%), IVA 1-3 days and change to OA: 21 (43.75%), IVA > 3 days: 6 (12.5%), and only OA: 3 (27.08%). The bivariate analysis did not show statistically significant differences in reconsultation (p = 0.81), rehospitalization (p = 0.44), and surgical site infection (p = 0.56) between the antibiotic scheme based on the postoperative clinical response and the traditional one regarding intra-abdominal collection rate, the hospital stays, and hospitalization costs.

Do cystic fibrosis centres with the lowest FEV1 still use the least amount of intravenous antibiotics? A registry-based comparison of intravenous antibiotic use among adult CF centres in the UK

BACKGROUND

The Epidemiologic Study of Cystic Fibrosis using 1995-1996 and 2003-2005 data found that CF centres with lowest FEV₁ tended to use fewer intravenous antibiotics. We repeated the analyses using 2013-2014 UK CF registry data to determine if this was still the case.

METHODS

Analysing data for 2013 and 2014 separately, 28 adult CF centres were ranked according to median % age-adjusted FEV₁. The top 7 centres were placed in the 'upper quarter' (best FEV₁), the bottom 7 centres in 'lower quarter' (lowest FEV₁), and the rest in 'middle half'. IV use was stratified according to %FEV₁, then compared between the three groups.

RESULTS

Centres in the 'upper quarter' and 'middle half' used significantly more IV antibiotics compared to centres in the 'lower quarter' (van Elteren test P-value<0.001). Regression analyses showed that people with CF attending centres in the 'upper quarter' or 'middle half' are 30-50% more likely to receive at least one IV course per year compared to people attending centres in the 'lower quarter'.

CONCLUSIONS

CF centres with lowest FEV₁ are still distinguished by lower use of intravenous antibiotics.
