Analysis of abbreviations used by residents in admission notes and discharge summaries

Nurses engaging with referral letters and discharge summaries: A qualitative study

AIMS

To investigate the ways that nurses engage with referral letters and discharge summaries, and the qualities of these documents they find valuable for safe and effective practice.

DESIGN

This study comprised a qualitative, case-study design within a constructivist paradigm using convenience sampling.

METHODS

Interviews were conducted with nurses to investigate their practices relating to referral letters and discharge summaries. Data collection also involved nurses' examination and evaluation of a diverse range of 10 referral letters and discharge summaries from medical records at two Australian hospitals through focus-group sessions. The data were transcribed and analysed inductively.

RESULTS

In all, 67 nurses participated in interviews or focus groups. Nurses indicated they used referral letters and discharge summaries to inform their work when caring for patients at different times throughout their hospitalisation. These documents assisted them with verbal handovers, to enable them to educate patients about their condition and treatment and to provide a high standard of care. The qualities of referral letters and discharge summaries that they most valued were language and communication, an awareness of audience and clinical knowledge, as well as balancing conciseness with comprehensiveness of information.

CONCLUSION

Nurses relied on referral letters and discharge summaries to ensure safe and effective patient care. They used these documents to enhance their verbal handovers, contribute to patient care and to educate the patient about their condition and treatment. They identified several qualities of these documents that assisted them in maintaining patient safety including clarity and conciseness of information.

IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE

It is important that referral letters and discharge summaries are written clearly, concisely and comprehensively because nurses use them as key sources of evidence in planning and delivering care, and in communicating with other health professionals in relaying goals of care and implementing treatment plans.

IMPACT

Nurses reported that they regularly used referral letters and discharge summaries as valuable sources of evidence throughout their patients' hospitalisation. The qualities of these documents which they most valued were language and communication styles, awareness of audience and clinical knowledge, as well as balancing conciseness with comprehensiveness of information. This research has important impact on the patient experience in relation to encouraging effective referral letter and discharge summary writing.

Prevalence and Risk Factors for Dangerous Abbreviations in Malaysian Electronic Clinical Notes

Medical abbreviations can be misinterpreted and endanger patients' lives. This research is the first to investigate the prevalence of abbreviations in Malaysian electronic discharge summaries, where English is widely used, and elicit the risk factors associated with dangerous abbreviations. We randomly sampled and manually annotated 1102 electronic discharge summaries for abbreviations and their senses. Three medical doctors assigned a danger level to ambiguous abbreviations based on their potential to cause patient harm if misinterpreted. The predictors for dangerous abbreviations were determined using binary logistic regression. Abbreviations accounted for 19% (33,824) of total words; 22.6% (7640) of those abbreviations were ambiguous; and 52.3% (115) of the ambiguous abbreviations were labelled dangerous. Increased risk of danger occurs when abbreviations have more than two senses (OR = 2.991; 95% CI 1.586, 5.641), they are medication-related (OR = 6.240; 95% CI 2.674, 14.558), they are disorders (OR = 7.771; 95% CI 2.054, 29.409) and procedures (OR = 3.492; 95% CI 1.376, 8.860). Reduced risk of danger occurs when abbreviations are confined to a single discipline (OR = 0.519; 95% CI 0.278, 0.967). Managing abbreviations through awareness and implementing automated abbreviation detection and expansion would improve the quality of clinical documentation, patient safety, and the information extracted for secondary purposes.

Structure, content, unsafe abbreviations, and completeness of discharge summaries: A retrospective analysis in a University Hospital in Austria

RATIONALE AND OBJECTIVE

The discharge summary (DS) is one of the most important instruments to transmit information to the treating general physician (GP). The objective of this study was to analyse important components of DS, structural characteristics as well as medical and general abbreviations.

METHOD

One hundred randomly selected DS from five different clinics were evaluated by five independent reviewers regarding content, structure, abbreviations and conformity to the Austrian Electronic Health Records (ELGA) using a structured case report form. Abbreviations of all 100 DS were extracted. All items were scored on a 4-point Likert-type scale ranging from "strongly agree" to "strongly disagree" (or "not relevant"). Subsequently, the results were discussed among reviewers to achieve a consensus decision.

RESULTS

The mandatory fields, reason for admission and diagnosis at discharge were present in 80% and 98% of DS. The last medication was fully scored in 48% and the recommended medication in 94% of 100 DS. There were significant overall differences among clinics for nine mandatory items. In total, 750 unexplained abbreviations were found in 100 DS.

CONCLUSIONS

In conclusion, DS are often lacking important items. Particularly important are a detailed medication history and recommendations for further medication that should always be listed in each DS. It is thus necessary to design and implement changes that improve the completeness of DS. An important quality improvement can be achieved by avoiding the use of ambiguous abbreviations.

Danger in discharge summaries: Abbreviations create confusion for both author and recipient

BACKGROUND

The transition from hospital inpatient care to medical care in the community is a high-risk period for adverse events. Inadequate communication, including low quality or unavailable discharge summaries, has been shown to impact patient care.

AIMS

Assess use of abbreviations in clinical handover documents from inpatient hospital teams to general practitioners (GPs), and the interpretation of these abbreviations by GPs and hospital-based junior doctors.

METHODS

Retrospective audit of 802 discharge summaries completed during a one-week period in 2017 by a Queensland regional health service. GPs and local junior doctors then attempted interpretation of twenty relevant abbreviations.

RESULTS

99% (794) discharge summaries included abbreviations. 1612 different abbreviations were used on 16 327 occasions. The median number of abbreviations per discharge summary was 17 (range 0-86). 254 GPs and 62 junior doctors responded to a survey which found that no abbreviation was interpreted the same by all respondents. GPs and junior doctors were unable to offer any interpretation in 17.9% and 15.2% of cases respectively. GPs offered a greater range of interpretations than junior doctors, with a median of 9 and 3 different interpretations per abbreviation respectively. 94% (239) of GPs felt that the use of abbreviations in discharge summaries had the potential to impact patient care. 152 (60%) GPs felt that time spent clarifying abbreviations in discharge summaries could be excessive.

CONCLUSIONS

Abbreviations are often used in discharge summaries, yet poorly understood. This has the potential to impact patient care in the transition period after hospitalisation This article is protected by copyright. All rights reserved.

A deep database of medical abbreviations and acronyms for natural language processing

The recognition, disambiguation, and expansion of medical abbreviations and acronyms is of upmost importance to prevent medically-dangerous misinterpretation in natural language processing. To support recognition, disambiguation, and expansion, we present the Medical Abbreviation and Acronym Meta-Inventory, a deep database of medical abbreviations. A systematic harmonization of eight source inventories across multiple healthcare specialties and settings identified 104,057 abbreviations with 170,426 corresponding senses. Automated cross-mapping of synonymous records using state-of-the-art machine learning reduced redundancy, which simplifies future application. Additional features include semi-automated quality control to remove errors. The Meta-Inventory demonstrated high completeness or coverage of abbreviations and senses in new clinical text, a substantial improvement over the next largest repository (6–14% increase in abbreviation coverage; 28–52% increase in sense coverage). To our knowledge, the Meta-Inventory is the most complete compilation of medical abbreviations and acronyms in American English to-date. The multiple sources and high coverage support application in varied specialties and settings. This allows for cross-institutional natural language processing, which previous inventories did not support. The Meta-Inventory is available at https://bit.ly/github-clinical-abbreviations.

Design and preliminary evaluation of a newly designed patient-friendly discharge letter - a randomized, controlled participant-blind trial

BACKGROUND

Low health literacy has been associated with poor health outcome and impaired use of healthcare services. The hospital discharge letter represents a key source of medical information for patients and can be used to address the problem of low health literacy. The aim of this project was to develop and evaluate a new, patient-directed, version of the discharge letter.

METHODS

Based upon two conventional discharge letters (CDL; one surgical and one medical letter), two new, patient-friendly discharge letters (PFDL) were designed following 5 key principles: short sentences, few abbreviations, large font size, avoidance of technical terms and no more than 4 pages length. Medical undergraduates were randomized into two blinded groups (CDL, PFDL) and asked to assess the assigned letter for the 3 domains structure, content and patient-friendliness. Subsections were rated on a 6-point Likert scale (1 = completely agree, 6 = completely disagree), the results of the survey were compared using the Mann-Whitney-U-Test with a p < 0.05 being the level of significance.

RESULTS

In total, 74 undergraduates participated in this study. PFDL (35 participants) were rated significantly better than CDL (39 participants) regarding structure (median 1 vs. 2, p = 0.005), content (1 vs. 3, p < 0.001) and patient-friendliness (2 vs. 6, p < 0.001). Of all 17 subsections, PFDL were rated significantly better in 12 cases, and never worse than CDL.

CONCLUSIONS

PFDL were rated significantly better than their CDL counterparts. Medical undergraduates were considered the ideal cohort, not being medical lays and yet unbiased regarding everyday clinical practice procedures. Further tests evaluating the impact of the PFDL on patient comprehension and health literacy are necessary.

Attitudes of physicians towards target groups and content of the discharge summary: a cross-sectional analysis in Styria, Austria

OBJECTIVES

The discharge summary (DS) represents one of the most important instruments to ensure a safe patient discharge from the hospital. They sometimes have poor quality in content and often include medical jargon, which the patient and their relatives cannot easily understand. Therefore, many risks for patient safety exist. This study investigated the questions for whom the DS is and which contents are necessary to ensure a safe treatment.

DESIGN

Cross-sectional analysis.

SETTING

Styria, Austria.

PARTICIPANTS

3948 internal and external physicians were consulted.

INTERVENTIONS

An online survey consisting of 24 questions was conducted. The survey was distributed to physicians working in the province of Styria, Austria, in 2018 over a period of 6 months.

MAIN OUTCOMES AND MEASURES

Attitudes of internal and external physicians in terms of target group, content and health literacy.

RESULTS

In total, 1060 physicians participated in the survey. The DS is considered as a communication tool among physicians (97.9%) and the patients are also indicated as addressees (73.5%). Furthermore, there is a high level of agreement that understandable information in the DS leads to fewer questions of the patients (67.9%).

CONCLUSION

In conclusion, the DS is not only seen as a document for the further treating physician but is also relevant for the patient. Incorporating the patient into their treatment at all levels may possibly strengthen the individual health literacy of the patient and their caring relatives.
