The need to address poor numeracy skills in the emergency department environment

Nurse academics' self-reported insights into the teaching of undergraduate nursing numeracy: A national cross-sectional study

AIMS

The aim of this research was to explore the teaching of undergraduate nursing numeracy in tertiary education settings in Australia. Specifically, it explored and identified: (1) the most common basic numeracy concepts taught, (2) additional training and resources to support numeracy teaching, (3) who is best placed to teach numeracy and (4) the preferred methods of teaching medication calculations.

BACKGROUND

Nurse academics are required to teach nursing numeracy to undergraduate nursing students who enter university unprepared to accurately calculate medication dosages. It is important that students understand numeracy concepts as this is then applied to contextualised clinical applications. Nurse academics teach basic numeracy; however, the literature reveals that nurse academics do not consider themselves mathematics teachers and that experts in this area are better suited to teaching this skill. There are a dearth of studies about the nurse academics who conduct the teaching and this study seeks to fill that gap by exploring firsthand the nurse academics' self-reported insights into the teaching of undergraduate nursing numeracy.

DESIGN

Cross-sectional survey. The setting was Australian universities that deliver an accredited undergraduate nursing degree.

METHODS

Purposive sampling was used to recruit Australian nurse academics (n = 170), sessional or permanent who currently teach all aspects of nursing numeracy and medication calculations to undergraduate nursing students. Data were collected between Nov 2023 - Feb 2024 using an online survey platform and analysed using a descriptive content analysis.

RESULTS

Nurse academics taught basic arithmetic most commonly (92 %), yet most (90 %) had not received professional development or additional training in how to teach these concepts. To assist with numeracy teaching, resources were requested (47 %) as were the need for mathematics learning support staff (82 %). The formula method was most commonly taught (91 %), however, most participants (94 %) were willing to learn and to teach other methods of calculating medications.

CONCLUSIONS

This research suggests an evidenced-based education framework be created to support and guide nurse academics when teaching all aspects of nursing numeracy and medication calculations. Building the teaching capacity of nurse academics in this vital area will enhance student competence and contribute to patient safety.

Numeracy Education for Health Care Providers: A Scoping Review

INTRODUCTION

Health numeracy (numerical literacy) refers to an individual's ability to use numerical information to make effective health decisions. Numeracy is fundamental in the role of a health care provider, forming the basis of evidence-based medicine and effective patient-provider communication. Despite a high level of education, many health care providers struggle with numeracy. Numeracy is often integrated into training curricula; however, teaching modality, competencies covered, learner satisfaction, and effectiveness of these educational interventions varies.

METHOD

A scoping review was conducted to explore and summarize what is known about numeracy skills education programs for health care providers. A comprehensive literature search was conducted from January 2010 to April 2021 in 10 databases. Controlled vocabulary terms and text words were used. The search was restricted to human studies, adults, and the English language. Articles were included if they were related to numeracy education for health care providers or trainees and provided details regarding methods, evaluation, and results.

RESULTS

The literature search retrieved 31,611 results and 71 met the inclusion criteria. Most interventions were conducted in a university setting, and targeted nursing students, medical students, resident physicians, and pharmacy students. Common numeracy concepts included statistics/biostatistics, medication calculations, evidence-based medicine, research methodology, and epidemiology. A variety of teaching modalities were used, which most often combined active approaches (eg, workshops, laboratories, small-group exercises, and discussion boards) with passive approaches (eg, traditional lectures and didactic teaching). Measured outcomes included knowledge and skills, self-efficacy, attitudes, and engagement.

DISCUSSION

Although efforts have been made to incorporate numeracy into training curricula, greater emphasis should be placed on developing strong numeracy skills in health care providers, particularly given the role numerical information plays in clinical decision making, evidence-based practices, and patient-provider communication.

An Evaluation of Health Numeracy among Radiation Therapists and Dosimetrists

Purpose

Medical errors in radiation oncology sometimes involve tasks reliant on practitioners’ grasp of numeracy. Numeracy has been shown to be suboptimal across various health care professionals. Herein, we assess health numeracy among American Society of Radiologic Technologists (ASRT) members.

Methods and materials

The Numeracy Understanding for Medicine instrument (NUMi), an instrument to measure numeracy in the general population, was adapted to oncology for this study and distributed to ASRT members (n = 14,228) in 2017. Per NUMi scoring, health numeracy scores were categorized as low (0-7), low average (8-12), high average (13-17), or high (18-20). The impact of cGy versus Gy on numeracy performance was investigated. Spearman’s rho and a Wilcox-Mann-Whitney test were used for comparisons between the different groups.

Results

A total of 662 eligible participants completed the instrument and identified as radiation oncology professionals. In the cGy and Gy NUMi scores, approximately 2% of respondents scored low-average, approximately 40% scored high-average, and approximately 58% scored high, with a median score of 18.0. Although the optimum NUMi score for ASRT members is unknown, one might expect our cohort to have numeracy skills at least as high as college freshmen. Roughly one-sixth of our study group scored at or below the average score of college freshmen (NUMi = 15). In the subset analysis of NUMi questions pertaining to radiation dose unit (cGy vs Gy), respondents performed better with cGy (mean score: 2.94; range, 2-3) versus Gy (mean: 2.91; range, 0-3; P = .011).

Conclusions

In this study of limited sample size, overall numeracy is quite good compared with the general population. However, the range of scores is wide, and some respondents have lower scores that may be concerning, suggesting that numeracy may be an issue that requires improvement for a subset of the studied cohort. Performance was superior with the unit cGy; thus, the adoption of cGy as the standard unit is reasonable.

Empirical relationships between numeracy and treatment decision making: A scoping review of the literature

OBJECTIVES

To determine what is known from the existing literature about empirical relationships between numeracy and the three stages of the treatment decision making process (information exchange, deliberation, and deciding on the treatment to implement). We also examined if, and how, numeracy was mentioned in relation to health literacy.

METHODS

A search of four databases returned 2772 records. After de-duplication and three levels of relevance screening, 38 primary studies were included in this review.

RESULTS

Relationships between numeracy and the information exchange stage have received greater attention than relationships between numeracy and the deliberation and deciding on the treatment to implement stages. The lack of overlap in the empirical relationships examined in studies, the measure(s) of numeracy used, and the characteristics of study populations, made findings difficult to compare. Multiple knowledge gaps and measurement-related problems were identified. Numeracy and health literacy have largely been treated as separate concepts.

CONCLUSION

More research is needed to better understand the importance of numeracy and health literacy to treatment decision making.

PRACTICE IMPLICATIONS

Decision aids designed for patients with different levels of health literacy may not meet the needs of patients with different levels of numeracy. The numeracy skills of health professionals require attention.
