ChemoPalRx-A Mobile App That Enhances Chemotherapy Prescription Accuracy: A Cross-Sectional Study

PURPOSE

ChemoPalRx is a novel provider order entry mobile application for chemotherapy. This study aims to evaluate the accuracy of prescribing chemotherapy using ChemoPalRx versus handwritten orders at a safety-net hospital in Los Angeles.

METHODS

In a cross-sectional study from October 2019 to December 2019, we evaluated all outpatient chemotherapy orders for accuracy. Our primary predictor was type of prescription, dichotomized as handwritten or ChemoPalRx. Primary outcome was accuracy, dichotomized as accurate if no error was made on an order and as inaccurate if any error was made. Preplanned subgroup analyses were performed with covariates including provider experience, complexity of order, and day of order submission. We characterized error type and analyzed our data using univariate and multivariate logistic regression models.

RESULTS

Among 288 orders (78.5% handwritten; 21.5% ChemoPalRx), prescription accuracy was higher among ChemoPalRx (93.5%) compared with handwritten orders (81.4%; P = .012). In multivariate analysis, prescription accuracy remained superior for ChemoPalRx after adjusting for provider experience, complexity of order, and day of order submission (adjusted odds ratio, 1.82; P = .012). Compared with handwritten orders, ChemoPalRx orders had less missing or incorrect information (1.6% v 13.7%; P = .0016). ChemoPalRx orders were also more accurate on prescriptions that contained two or fewer medications (92.2% v 80.2%; P = .032), submitted on the highest patient-volume clinic day of the week (96.7% v 83.2%; P = .035), and generated by a senior fellow or an attending (97.3% v 76.9%; P = .001).

CONCLUSION

ChemoPalRx is associated with improved chemotherapy prescription accuracy over handwritten orders in the safety-net hospital setting and may serve as an alternative prescribing tool for oncology practices.

Chemotherapy medication errors

Although chemotherapy is a well established treatment modality, chemotherapy errors represent a potentially serious risk of patient harm. We reviewed published research from 1980 to 2017 to understand the extent and nature of medication errors in cancer chemotherapy, and to identify effective interventions to help prevent mistakes. Chemotherapy errors occur at a rate of about one to four per 1000 orders, affect at least 1-3% of adult and paediatric oncology patients, and occur at all stages of the medication use process. Oral chemotherapy use is a particular area of growing risk. Our knowledge of chemotherapy errors is drawn primarily from single-institution studies at university hospitals and referral centres, with a particular focus on prescription orders and pharmacy practices. Although the heterogeneity of research methods and measures used in these studies limits our understanding of this issue, the rate of chemotherapy error-related injuries is generally lower than those seen in comparable studies of general medical patients. Although many interventions show promise in reducing chemotherapy errors, most have little empirical support. Additional research is needed to understand and to mitigate the risk of chemotherapy medication errors.

A virtual centralized cytotoxic preparation unit simulation to evaluate the pharmacy staff knowledge

BACKGROUND

The risk of medication errors related to drug preparation unit cannot be totally avoided because of human interference. The aim of this study is to investigate the background and knowledge of the pharmacy staff by replicating the cytotoxic preparation unit with potential errors.

METHODS

A 10-m² room was provided to duplicate the centralized chemotherapy unit with three areas reproducing virtually the equipment preparation bench, the isolator, and the dispensing bench. The 14 situations selected by experts were integrated to each corresponded area. For each participant, a form was given and answers were analyzed by two independent experts. Statistical processing data were performed using GraphPad Prism® software.

RESULTS

A total of 19 professionals participated in error simulation workshop over a one-month period. The overall rate of correct responses was 58 ± 19%. In five situations, correct responses rate was lower than 50%: wrong drug batch related to the preparation sheet (40%), inappropriate sterilizing conditions (15%), the time on the preparation sheet provides an expired expiry date for melphalan preparation (45%), a maximum drug dose exceeded (25%), the dispensing form not corresponds to the preparation sheet and final product label (30%). The rate of correct responses was 45 ± 25% for professionals not specifically dedicated to chemotherapy preparation. The overall satisfaction workshop rate was 8.7 ± 1.0 out of 10.

CONCLUSION

This study showed the importance of training programs to sensitize personal staff to the risks of chemotherapy preparation and prevent errors.

Terms used in patient safety related to medication: a literature review

PURPOSE

There is a lack of homogeneity in the terminology used in the context of patient safety related to medication. The aim of this review was to identify the terms and definitions used in patient safety related to medication within the scientific literature.

METHODS

Original and review articles that were indexed between 1998 and 2008 in MEDLINE and EMBASE and contained terms used in patient safety related to medication were included. Terms and definitions were extracted and categorised according to whether its definition referred to the process of medication use, or to the clinical outcome of medication use, or both.

RESULTS

Of 2564 articles, 147 were included. Sixty terms used in patient safety related to medication with 189 different definitions were identified. Among terms that referred only to the process of medication use (n = 23), medication error provided the greatest number of definitions (n = 29). Among terms that referred only to the clinical outcome of medication use (n = 31), adverse drug event provided the greatest number of definitions (n = 15). Finally, among terms that referred both to the process of use and to the clinical outcome of medication use (n = 13), drug-related problem provided the greatest number of definitions (n = 7).

CONCLUSIONS

A multitude of terms and definitions are used in patient safety related to medication. This heterogeneity makes it difficult to compare the results among studies and to appreciate the true magnitude of the problem. Classifying and unifying the terminology is necessary to advance in patient safety strategies.

Drug administration error related to computerized prescribing

Introduction. One of the main reasons for the implementation of computer-based prescribing was to reduce medication errors. However, the risk has not fallen to zero and new kinds of errors have been detected.

Setting. The following case relates one of these medication errors involving a preparation of vincristine. This antineoplastic drug was injected to a patient via a subcutaneous route of administration instead of an intravenous bolus injection.

Results. Consequently, a cutaneous erythema appeared. This incident resulted from an error in the programming of the administration route of the protocol operated by a pharmacist and a physician. The pharmacist, who was responsible for the validation of the computerized medical order and then for the compounding and the dispensing of the drug, did not detect the error.

Conclusion. This case highlights the need of improved and irreproachable therapeutic protocols. Recorded in a database, they must be validated pharmaceutically and medicinally to secure computer-based prescribing, drug handling, dispensing, and administering of the antineoplastic drugs. Even if the pharmaceutical analysis of prescriptions is made easier with computerization, we encourage the training of nurses and the evaluation of their knowledge as well as the necessity for pharmacists to learn to detect new kinds of errors and to verify periodically protocols.

Errors in medicine administration: how can they be minimised?

Errors in medicine administration often go unnoticed and unreported. This article describes three medicine-related errors and provides recommendations to reduce risk. All medicine-related errors should be reported locally and to the National Patient Safety Agency (NPSA) so that they can be collated and trends identified. Electronic prescribing and patient/medicine identification by bar codes, double checking and using colour coded syringes for intravenous and enteral administration, employing more clinical pharmacists and regular education may reduce medicine-related errors.
