Appropriateness of oral medication delivery devices available in community pharmacies

Devices for securing and administering pediatric compounded oral liquids: survey results from French university hospitals

Oral liquid forms, either commercial or compounded, are preferred in pediatrics due to their suitability for weight-based dosing and acceptability for children. The choice of dosing delivery devices associated with oral liquid forms is important to ensure accurate dosing, ease of administration, and patient safety. Given the prevalence of compounding in pediatric settings, this study aimed to investigate the practices among French university hospitals concerning the selection of dosing delivery devices associated with compounding oral liquid forms for children. An online survey was distributed to pharmacists involved in compounding in French university hospitals. The survey covered aspects such as the presence of child-resistant caps, types of dosing devices, the presence of bottle adapters, and the type of bottle adapters used. Among the 36 hospital pharmacies contacted, 24 responded to the survey. One pharmacy employed child-resistant caps for compounded liquid forms. Enteral syringes emerged as the primary dosing device (71%), with a minority using luer/luer-lock syringes (21%). Spoon and measuring cup usage was reported by none. Approximately two-thirds of the pharmacies (67%) used a bottle adapter in conjunction with the sampling device.   Conclusion: The study highlighted diversity in the practices of French university hospitals regarding dosing delivery devices associated with compounding oral liquid forms for pediatric patients. The findings underscored the need for standardized guidelines to streamline practices and enhance safety and precision in compounded medication administration for children. What is Known: • Administration devices are important to ensure the correct administration of the required dose of oral liquids in pediatrics. • For compounded oral liquid forms, the selection and supply of administration devices are managed by compounding pharmacies from those available on the market. What is New: • The study highlighted the variability of administration devices associated with compounded liquids for oral use in French hospital pharmacies.

Stepping into small shoes: Gaining user perspective on appropriate administration devices for paediatric medication in India

A cross sectional pan-India study about use of administration devices for paediatric oral and inhalation medicines was conducted with a diverse pool of participants of various age groups. Via 634 respondents from more than 15 states in India, this study has identified the administration devices commonly used by parents/caregivers for children 0 to 18 years and by children over 10 years. It has provided insights on device ease of use, challenges faced and recommendations to facilitate the correct use of administration devices for paediatric oral and inhalation medicines. Ethics approval (DPSRU-BREC/2020/A/008)) was obtained from the Biomedical Research Ethics Committee of Delhi Pharmaceutical Sciences and Research University. The survey was completed by parents only (n = 514) and jointly by both parents and children (n = 120). The mean age of the child was 7.2 ± 4.96 years. 72% of the respondents reported that an oral medicine had been taken recently, 6.3% reported that an inhaled medicine had been taken and the remaining 21.9% reported that both an oral and inhaled medicine had been taken. The use of measuring cup was most prevalent followed by household spoons. The mean of the score for ease of use was found to be highest 4.6 ± 0.50 for oral syringe and lowest (3.8 ± 0.76) for measuring cups. The majority of them found the oral device easy to use. Difficulties were reported mostly for measuring cups and household spoons and were related to a lack of user instructions and measuring difficulties. The respondents who found the device easy to use had mostly received clear instructions from healthcare professionals. Compared to oral devices, there were very limited responses for inhalation devices (n = 175/634). Nebulisers with facemasks were most frequently used followed by manually actuated Metered dose inhalers with and without spacer. The mean of the ease-of-use score for dry powder inhalers was found to be highest (4.2 ± 0.37) followed by mist inhalers (4.0 ± 0) and manually actuated pressurised metered dose inhalers (4.0 ± 0.71). The nebulisers with facemask were reported to be difficult to use by most of the respondents despite receiving clear instructions from healthcare professionals. The study findings add evidence to the understudied area of user experiences and perspectives on administration devices for oral and inhalation medicines in India. It highlights a need for initiatives to improve the usability, availability, and affordability of administration devices for children in India. Awareness on the importance of proper use of devices needs to be raised and sustained about the existence of affordable administration devices.

Comparison of Dosing Accuracy Between the ENFit LDT and a Neonatal-Specific ISO-Compliant Enteral Syringe

OBJECTIVE

To evaluate the dosing accuracy of 2 female enteral syringe types for use in neonates.

METHODS

This was an in vitro study evaluating dosing accuracy of ENFit with low dose tip (LDT) and Nutrisafe2 (NS2) syringes. Acceptable dosing variance (DV) was +/- 10%. Outcomes included tests exceeding 10% DV and DV by syringe size, dispensing source, and intended dosing volume.

RESULTS

A total of 300 tests were performed (LDT = 150, NS2 = 150) with 3 syringe sizes (0.5, 1, 3 or 2.5 mL). Compared with NS2, LDT had significantly more tests with unacceptable DV (48% vs 4.7%, p < 0.0001) and higher absolute DV (11.9% vs 3.5%, p < 0.001). Dosing variance was inversely proportional to syringe size, where the smallest syringes were least accurate (0.5 mL LDT 16.1% vs 4.6%, p < 0.001). The largest syringes had acceptable DV (3 mL LDT 8.8% vs 2.5 mL NS2 3.3%, p < 0.001). Bulk bottle with adapters demonstrated a higher DV with LDT compared with NS2 (13.3% vs 3.9%, p < 0.001). Medication cups without adapters were associated with acceptable DV for both LDT and NS2 (9.7% vs 2.9%, p < 0.001).

CONCLUSIONS

The Nutrisafe2 syringe has greater dosing accuracy as compared with ENFit LDT syringe. Smaller syringes are associated with greater dosing inaccuracy, but this effect was within acceptable DV for the NS2 syringe. Bulk bottle adapters did not improve the accuracy of the LDT. More clinical evaluations are needed to determine if the ENFit can be safely used in the neonatal population.

Identification of Errors in Pediatric Prescriptions and Interventions to Prevent Errors: A Survey of Community Pharmacists

OBJECTIVES

Assess the competency of community pharmacists in identifying errors in pediatric prescriptions and to determine how often pharmacists perform interventions known to mitigate the likelihood of error. The study sought to recognize factors that may impact the pharmacist's ability to identify and mediate these errors, and to detect barriers that limit the role of the pharmacist pediatric patient care.

METHODS

A survey was distributed through the University of Illinois at Chicago College of Pharmacy Alumni Network and the Illinois Pharmacists Association email listservs. Pharmacists practicing in a retail setting within the last 5 years were included. Three prescription scenarios for commonly used pediatric medications with corresponding questions were created to assess a pharmacist's ability to identify errors. Demographics pertaining to the pharmacist and the practice site, as well as information about dispensing practices, were collected. Logistic regression was used to identify factors that might impact the pharmacists' ability to identify errors.

RESULTS

One hundred sixty-one respondents began the survey and 138 met inclusion criteria. In 15% to 59% of scenario-based questions, pharmacists did not appropriately identify errors or interventions that would decrease the likelihood of error. Correct identification of doses was associated with total prescription volume in one scenario and with pediatric prescription volume in another scenario. Pharmacists did not consistently label prescriptions for oral liquids in milliliters or dispense oral syringes. Barriers to pharmacist involvement included availability and interest of the caregiver, ability to contact prescriber, and pharmacy staffing.

CONCLUSION

Community pharmacists did not consistently identify medication errors or use interventions known to mitigate error risk.

Design of a Precision Medication Dispenser: Preventing Overdose by Increasing Accuracy and Precision of Dosage

Liquid medication overdose in pediatric patients results in over 70000 visits to the emergency room yearly in the USA. Various studies have demonstrated that the root cause of this high incidence is due to user and device error in dose measurement. The standard measuring cup and syringe suffer from the challenge of accurately measuring and dispensing viscous liquids, which comprise the majority of children’s medication formulations. Here, we describe the development of a precision medication dispenser that overcomes challenges associated with viscous fluid flow at low volumes and flow rates, while incorporating various ergonomic and user-friendly features. The device performs with >95% accuracy and 94% precision across the 1–5-mL range of volume, a significant improvement when compared to current commercially available dispensers.
