Perception of the safety culture in a critical area

INTRODUCTION

Critical care Area (CCA) is one of the most complex in the hospital system, requiring a high number of interventions and handling of amounts of information. Therefore, these areas are likely to experience more incidents that compromise patient safety (PS).

AIM

To determine the perception of the healthcare team in a critical care area about the patient safety culture.

METHOD

Cross-sectional descriptive study, September 2021, in a polyvalent CCA with 45 beds, 118 health workers (physicians, nurses, auxiliary nursing care technicians). Sociodemographic variables, knowledge of the person in charge in PS and their general training in PS and incident notification system were collected. The validated Hospital Survey on Patient Safety Culture questionnaire, measuring 12 dimensions was used. Positive responses with an average score ≥75%, were defined as an area of strength while ≥50% negative responses were defined as an area of weakness. Descriptive statistics and bivariate analysis: X2 and t-Student tests, and ANOVA. Significance p ≤ 0.05.

RESULTS

94 questionnaires were collected (79.7% sample). The PS score was 7.1 (1.2) range 1-10. The rotational staff scored the PS with 6.9 (1.2) compared to 7.8 (0.9) for non-rotational staff (p = 0.04). A 54.3% (n = 51) was familiar with the incident reporting procedure, 53% (n = 27) of which had not reported any in the last year. No dimension was defined as strength. There were three dimensions that behaved like a weakness: security perception: 57.7% (95% CI: 52.7-62.6), staffing: 81.7% (95% CI: 77.4-85.2) and management support: 69 .9% (95% CI: 64.3-74.9).

CONCLUSIONS

The assessment of PS in the CCA is moderately high, although the rotational staff has a lower appreciation. Half of the staff do not know the procedure for reporting an incident. The notification rate is low. The weaknesses detected are perception of security, staffing and management support. The analysis of the patient safety culture can be useful to implement improvement measures.

Hepatoxicity induced by clozapine: Case report and brief review

INTRODUCTION

Antipsychotics are drugs that can produce transient elevations of hepatic enzymes. Clozapine is an atypical antipsychotic used in treatment-resistant schizophrenia and there is evidence that it can produce elevations of hepatic transaminases, expression of liver damage in a hepatocellular pattern.

METHODS

Case report and non-systematic review of the relevant literature.

CASE PRESENTATION

A 39-year-old woman with a diagnosis of paranoid schizophrenia attended the emergency department of a general hospital for nausea, vomiting and jaundice that appeared after the initiation of clozapine. There was no clinical improvement during hospitalisation, and death occurred after 44 days.

LITERATURE REVIEW

Clozapine can increase the liver enzyme levels transiently and asymptomatically; however, there are clinical criteria that recommend the withdrawal of the antipsychotic.

CONCLUSIONS

This is the third case reported in the literature of a fatal outcome of clozapine-induced hepatotoxicity.

Prone positioning in COVID-19 patients with acute respiratory distress syndrome and invasive mechanical ventilation

OBJECTIVE

To identify adverse events related to prone positioning in COVID-19 patients with severe disease and acute respiratory distress syndrome, to analyze the risk factors associated with the development of anterior pressure ulcers, to determine whether the recommendation of prone positioning is associated with improved clinical outcomes.

METHODS

Retrospective study performed in 63 consecutive patients with COVID-19 pneumonia admitted to intensive care unit on invasive mechanical ventilation and treated with prone positioning between March and April 2020. Association between prone-related pressure ulcers and selected variables was explored by the means of logistic regression.

RESULTS

A total of 139 proning cycles were performed. The mean number of cycles were 2 [1-3] and the mean duration per cycle was of 22h [15-24]. The prevalence of adverse events this population was 84.9 %, being the physiologic ones (i.e., hypo/hypertension) the most prevalent. 29 out of 63 patients (46%) developed prone-related pressure ulcers. The risk factors for prone-related pressure ulcers were older age, hypertension, levels of pre-albumin <21mg/dl, the number of proning cycles and severe disease. We observed a significant increase in the PaO₂/FiO₂ at different time points during the prone positioning, and a significant decrease after it.

CONCLUSIONS

There is a high incidence of adverse events due to PD, with the physiological type being the most frequent. The identification of the main risk factors for the development of prone-related pressure ulcers will help to prevent the occurrence of these lesions during the prone positioning. Prone positioning offered an improvement in the oxygenation in these patients.

Evaluation of tracheal intubations in a paediatric intensive care unit

INTRODUCTION

Tracheal intubation is a frequent procedure in paediatric intensive care units (PICUs) that carries a risk of complications that can increase morbidity and mortality.

PATIENTS AND METHODS

Prospective, longitudinal, observational study in patients intubated in a level III PICU between January and December 2020. We analysed the risk factors associated with failed intubation and adverse events.

RESULTS

The analysis included 48 intubations. The most frequent indication for intubation was hypoxaemic respiratory failure (25%). The first attempt was successful in 60.4% of intubations, without differences between procedures performed by staff physicians and resident physicians (62.5% vs 56.3%; P = .759). Difficulty in bag-mask ventilation was associated with failed intubation in the first attempt (P = .028). Adverse events occurred in 12.5% of intubations, and severe events in 8.3%, including 1 case of cardiac arrest, 2 cases of severe hypotension and 1 of oesophageal intubation with delayed recognition. None of the patients died. Making multiple attempts was significantly associated with adverse events (P < .002). Systematic preparation of the procedure with cognitive aids and role allocation was independently associated with a lower incidence of adverse events.

CONCLUSIONS

In critically ill children, first-attempt intubation failure is common and associated with difficulty in bag-mask ventilation. A significant percentage of intubations may result in serious adverse events. The implementation of intubation protocols could decrease the incidence of adverse events.

Neurological manifestations associated with COVID-19 vaccine

INTRODUCTION

Coronavirus disease 2019 (COVID-19) has spread rapidly, giving rise to a pandemic, causing significant morbidity and mortality. In this context, many vaccines have emerged to try to deal with this disease.

OBJECTIVE

To review the reported cases of neurological manifestations after the application of COVID-19 vaccines, describing clinical, analytical and neuroimaging findings and health outcomes.

METHODS

We carried out a review through bibliographic searches in PubMed.

RESULTS

We found 86 articles, including 13 809 patients with a wide spectrum of neurological manifestations temporally associated with COVID-19 vaccination. Most occurred in women (63.89%), with a median age of 50 years. The most frequently reported adverse events were Bell's palsy 4936/13 809 (35.7%), headache (4067/13 809), cerebrovascular events 2412/13 809 (17.47%), Guillain-Barré syndrome 868/13 809 (6.28%), central nervous system demyelination 258/13 809 (1.86%) and functional neurological disorder 398/13 809 (2.88%). Most of the published cases occurred in temporal association with the Pfizer vaccine (BNT162b2), followed by the AstraZeneca vaccine (ChAdOX1-S).

CONCLUSIONS

It is not possible to establish a causal relationship between these adverse events and COVID-19 vaccines with the currently existing data, nor to calculate the frequency of appearance of these disorders. However, it is necessary for health professionals to be familiar with these events, facilitating their early diagnosis and treatment. Large controlled epidemiological studies are necessary to establish a possible causal relationship between vaccination against COVID-19 and neurological adverse events.

Incidence and risk factors of adverse events in pediatric hemato-oncological patients: A cohort study

BACKGROUND

Pediatric hemato-oncological (HO) patients are highly susceptible to the occurrence of adverse events (AE), nevertheless few research has been done in this field. Our aim was to describe the incidence, type, severity and preventability of AE in these patients, including bone marrow transplant (BMT) patients, and to identify patient's risk factors for having an AE.

METHODS

Retrospective cohort study. Children under 18yo hospitalized at the HO or BMT ward in 2016 were eligible for the study. Type of AE, severity and preventability were described as absolute and relative frequencies. Cumulative incidence of patients with at least one AE (CI_AE) and the rate of occurrence of all AE were calculated. Risk factors (sex, recovery probability, comorbidities and being a BMT patient) were analyzed using logistic regression.

RESULTS

114 patients were included, 58% were male, average age was 8.7yo and 25 were BMT patients. 44 had at least one AE, with CI_AE of 38.6% (95%CI 29.7-47.5). Overall rate of occurrence of AE was 2.5 cases per 100 patients-day (95%CI 2.15-2.98). For BMT and non-BMT patients they were 2.8 (95%CI 2.2-3.6) and 2.5 (95%CI 1.98-3.1) respectively. Healthcare related infection was the most frequent AE. Most AE were moderate and with high preventability. Being a BMT patient was the only independent factor associated with the occurrence of at least one AE (OR=11.5, p<0.001).

CONCLUSIONS

Our findings suggest that AE tend to be moderate and preventable in HO pediatric patients. BMT patients seem to be at greater risk of having an AE. Strategies focused on patient safety need to account for their specific characteristics.

[Adverse events and essential actions for patient safety]

INTRODUCTION

The adverse events (AE) in hospitalized patients occur with increasing frequency due to the increase in complexity of medical care, which implies a greater risk of committing a human error inherent to the care, constituting a serious threat to the safety of the patient.

MATERIAL AND METHODS

Cross-sectional study, including patients older than 16years, with hospital stay longer than 24h and discharge from the general surgery service, patients treated in emergency observation units or other hospital services were not considered. AE were identified, classified by cause according to the essential actions for patient safety (EAPS), and compliance with the EAPS was verified.

RESULTS

352 clinical records were reviewed, 61 (17%) were positive on screening. Of the positives, 66% resulted in AE (47 cases). The prevalence of AE was 13%. The AE were: 40% related to procedures; 39% with infections; 17% with medication; 4% with patient identification. The EAPS with the best rating was EAPS5 and the lowest rating was EAPS4. The night shifts with the greatest opportunity area, only with 40% and 44% correct procedures.

CONCLUSIONS

The study shows that the two methodologies used, one to identify AE and the other to establish its causes and classification according to the EAPS, demonstrated usefulness and synergy for patient safety, when detecting AE, as well as determining their causes and evaluate compliance with the EAPS.

[Detection of adverse events in thyroid and parathyroid surgery using trigger tool and Minimum Basic Data Set (MBDS)]

OBJECTIVES

To compare the ability of the trigger tool) and the Minimum Basic Data Set (MBDS) in detecting adverse events (AE) in hospitalized surgical patients with thyroid and parathyroid disease.

METHODS

A descriptive, cross-sectional observational study, retrospective and cross-sectional study was conducted from May 2014 to April 2015 analysing retrospectively data on of patients submitted to thyroidectomy and parathyroidectomy in order to detect AE through the identification of triggers (an event often associated to an AE) and the MBDS. triggers and AE were located by systematic review of clinical documentation. The MBDS was got from the data base. Once an AE was detected, it was characterized.

RESULTS

203 AE were identified in 251 patients, being the 90.04% detected by trigger tool and 10.34% by MBDS. 126 patients had at least one AE (50.2%). Without the cases in which uncontrolled pain was the only AE, the percentage of patients that suffering AE was 38.65%. 187 AE were considered preventable and 16 AE were considered unpreventable. The trigger tool and the MBDS demonstrated a sensitivity of 91.27 and 13.49%, a specificity of 4.8 and 100%, a positive predictive value of 49,15 and 100%, and a negative predictive value of 35.29 and 53.42%, respectively. The triggers with more predictive power in AE detection were «antiemetic administration» and «calcium administration».

CONCLUSIONS

Trigger tool shows higher sensitivity for detecting AE than the MBDS. All the detected AE were considered low severity and most of them were preventable.

Factors attributable to the cancellation of programmed surgeries

Objective

To analyze the factors attributable to the cancellation of surgeries of a third level health institution in the city of Valledupar, Cesar / Colombia (2017-2018).

Material and methods

Descriptive, retrospective, cross-sectional study. Data from the hospital surgical unit adverse case file were collected for 6 surgical specialties.

Results

They showed that in 2017 there was a surgical suspension of 4% of the total of scheduled surgeries that were (3339), for 2018 the rate was 3% with a total of scheduled surgeries (1733). The reason for the suspension for both periods was the factor related to the patient's adverse conditions with 45.9 and 38.5% respectively. The specialty most affected for these cases was the specialty of general surgery with the same percentage value in both periods of 4%.

Conclusion

The results give us an idea of the factors present for the cancellation of scheduled surgeries and the need to apply measures to guarantee patient safety.

[Performance and optimisation of a trigger tool for the detection of adverse events in hospitalised adult patients]

OBJECTIVE

To characterise the performance of the triggers used in the detection of adverse events (AE) of hospitalised adult patients and to define a simplified panel of triggers to facilitate the detection of AE.

METHOD

Cross-sectional study of charts of patients from a service of internal medicine to detect EA through systematic review of the charts and identification of triggers (clinical event often related to AE), determining if there was AE as the context in which it appeared the trigger. Once the EA was detected, we proceeded to the characterization of the triggers that detected it. Logistic regression was applied to select the triggers with greater AE detection capability.

RESULTS

A total of 291 charts were reviewed, with a total of 562 triggers in 103 patients, of which 163 were involved in detecting an AE. The triggers that detected the most AE were "A.1. Pressure ulcer" (9.82%), "B.5. Laxative or enema" (8.59%), "A.8. Agitation" (8.59%), "A.9. Over-sedation" (7.98%), "A.7. Haemorrhage" (6.75%) and "B.4. Antipsychotic" (6.75%). A simplified model was obtained using logistic regression, and included the variable "Number of drugs" and the triggers "Over-sedation", "Urinary catheterisation", "Readmission in 30 days", "Laxative or enema" and "Abrupt medication stop". This model showed a probability of 81% to correctly classify charts with EA or without EA (p <0.001; 95% confidence interval: 0.763-0.871).

CONCLUSIONS

A high number of triggers were associated with AE. The summary model is capable of detecting a large amount of AE, with a minimum of elements.

[Comparison of the "Trigger" tool with the minimum basic data set for detecting adverse events in general surgery]

INTRODUCTION

Surgery is a high risk for the occurrence of adverse events (AE). The main objective of this study is to compare the effectiveness of the Trigger tool with the Hospital National Health System registration of Discharges, the minimum basic data set (MBDS), in detecting adverse events in patients admitted to General Surgery and undergoing surgery.

MATERIAL AND METHODS

Observational and descriptive retrospective study of patients admitted to general surgery of a tertiary hospital, and undergoing surgery in 2012. The identification of adverse events was made by reviewing the medical records, using an adaptation of "Global Trigger Tool" methodology, as well as the (MBDS) registered on the same patients. Once the AE were identified, they were classified according to damage and to the extent to which these could have been avoided. The area under the curve (ROC) were used to determine the discriminatory power of the tools. The Hanley and Mcneil test was used to compare both tools.

RESULTS

AE prevalence was 36.8%. The TT detected 89.9% of all AE, while the MBDS detected 28.48%. The TT provides more information on the nature and characteristics of the AE. The area under the curve was 0.89 for the TT and 0.66 for the MBDS. These differences were statistically significant (P<.001).

CONCLUSIONS

The Trigger tool detects three times more adverse events than the MBDS registry. The prevalence of adverse events in General Surgery is higher than that estimated in other studies.

[Analysis of an incident notification system and register in a critical care unit]

OBJECTIVE

To analyse the incident communicated through a notification system and register in a critical care unit.

METHODOLOGY

A cross-sectional descriptive study was conducted by performing an analysis of the records of incidents communicated anonymously and voluntarily from January 2007 to December 2013 in a critical care unit of adult patients with severe trauma.

STUDY VARIABLES

incident type and class, professional reports, and suggestions for improvement measures. A descriptive analysis was performed on the variables.

RESULTS

Out of a total of 275 incidents reported, 58.5% of them were adverse events. Incident distributed by classes: medication, 33.7%; vascular access-drainage-catheter-sensor, 19.6%; devices-equipment, 13.3%, procedures, 11.5%; airway tract and mechanical ventilation, 10%; nursing care, 4.1%; inter-professional communication, 3%; diagnostic test, 3%; patient identification, 1.1%, and transfusion 0.7%. In the medication group, administrative errors accounted for a total of 62%; in vascular access-drainage-catheter-sensor group, central venous lines, a total of 27%; in devices and equipment group, respirators, a total of 46.9%; in airway self-extubations, a total of 32.1%. As regards to medication errors, 62% were incidents without damage. Incident notification by profession: doctors, 43%, residents, 5.6%, nurses, 51%, and technical assistants, 0.4%.

CONCLUSIONS

Adverse events are the most communicated incidents. The events related to medication administration are the most frequent, although most of them were without damage. Nurses and doctors communicate the incidents with the same frequency. In order to highlight the low incident notification despite it being an anonymous and volunteer system, therefore, it is suggested to study measurements to increase the level of communication.

[Recommendations for institutional response to an adverse event]

INTRODUCTION

The organizational response after an Adverse Event (AE) is critical for the patient recovery and trust restoration in the health system. It is also crucial for the involved caregiver psychological recovery.

OBJECTIVE

To design a frame of recommendations to help the healthcare services, institutions and organizations to provide a systematic approach to an AE.

METHODS

A reduced group of authors performed a non-systematic review of the literature and developed an initial draft. The draft was sent to the rest of authors, who suggested modifications in structure, content, references and style throughout successive manuscript versions until a final one was accepted.

RESULTS

AE response includes the patient's clinical stabilization and a therapeutic plan to mitigate harm, the safeguard of used materials or health products involved, the appropriate disclosure to patient and family, the support of affected staff and their replacement if needed, the report to appropriate clinical and management heads, the event circumstances documentation and the starting of the AE investigation and analysis. Besides the professional, family and patient's trust and health recovery, the ultimate target of a correct AE response is the improvement of healthcare processes to prevent its repetition considering the AE as a system failure and learning and improving through its analysis.

[Perspective of nursing students on the communication and apologies to patients for adverse events: a descriptive study]

OBJECTIVES

To describe the approach to the communication and blame of an adverse by nursing students.

METHOD

A descriptive study on disclosure and apologies for adverse events by nursing students in the academic years 2011-12 and 2012-13. The study included group discussion and drafting a written communication to the injured patient about adverse events during hospitalization. An ad hoc checklist was used and an analysis was performed on items related to the disclosure and apologies issues.

RESULTS

A total of 126 nursing students were involved, and they created 21 written The facts about adverse events were reported in 81% of written communications, and 47.1% chose an abbreviated disclosure of the facts with no detailed explanation of adverse events. The facts were accurately reproduced in only 9.5% of written communications to the patients. One third (33.3%) apologized for the mistakes, and 47.6% required that the communication was signed by the Management. All (100%) of the nursing students chose not to report the health professionals who had participated during the events.

CONCLUSIONS

There is a fear to acknowledge errors within health centers. It is recommended that tools are developed for these future nursing professionals to make an open and honest disclosure of adverse events, as well as the apologies for them.

[Detection of adverse events in hospitalized adult patients by using the Global Trigger Tool method]

OBJECTIVES

To identify and characterize adverse events (AE) in an Internal Medicine Department of a district hospital using an extension of the Global Trigger Tool (GTT), analyzing the diagnostic validity of the tool.

METHODS

An observational, analytical, descriptive and retrospective study was conducted on 2013 clinical charts from an Internal Medicine Department in order to detect EA through the identification of 'triggers' (an event often related to an AE). The 'triggers' and AE were located by systematic review of clinical documentation. The AE were characterized after they were identified.

RESULTS

A total of 149 AE were detected in 291 clinical charts during 2013, of which 75.3% were detected directly by the tool, while the rest were not associated with a trigger. The percentage of charts that had at least one AE was 35.4%. The most frequent AE found was pressure ulcer (12%), followed by delirium, constipation, nosocomial respiratory infection and altered level of consciousness by drugs. Almost half (47.6%) of the AE were related to drug use, and 32.2% of all AE were considered preventable. The tool demonstrated a sensitivity of 91.3% (95%CI: 88.9-93.2) and a specificity of 32.5% (95%CI: 29.9-35.1). It had a positive predictive value of 42.5% (95%CI: 40.1-45.1) and a negative predictive value of 87.1% (95%CI: 83.8-89.9).

CONCLUSIONS

The tool used in this study is valid, useful and reproducible for the detection of AE. It also serves to determine rates of injury and to observe their progression over time. A high frequency of both AE and preventable events were observed in this study.
