Abstract

Background: The Institute for Healthcare Improvement (IHI) has proposed a new method, the Global Trigger Tool (IHI GTT), to detect and monitor adverse events (AEs) and provide information to implement improvement. In 2015, the Sicilian Health System adopted IHI GTT to assess the number, types and severity levels of AEs. The GTT was implemented in 44 of 73 Sicilian public hospitals and 18,008 clinical records (CRs) were examined. Here we present the standardized application of the GTT and the preliminary results of 14,706 reviews of CRs.
Methods: IHI GTT was adapted to the local context, and developed and implemented. Reviews of CRs were conducted by 199 professionals divided into 71 review teams consisting of three individuals: two of whom had clinical knowledge and expertise, and a physician to authenticate the AE. The reviewers entered data into a dedicated IT-platform. All 44 of the public hospitals were included, with approximately 300,000 inpatient yearly admission out of a population of approximately 5 million. In total, 14,706 CRs of inpatients from medicine, surgery, obstetric and ICU wards, from June 2015 to June 2018 were reviewed.
Results: In 975 (6.6%) CRs at least one AE was found. Approximately 20,000 patients of the 300,000 discharged each year in Sicily have at least one AE. In 5,574 (37.9%) CRs at least one trigger was found. A total of 1,542 AEs were found. The analysis of ROC curve shows that the presence of two triggers in a CR indicates an AE with a high probability. The most frequent type of AE was in-hospital related infection.
Conclusions: The GTT is an efficient method to identify AEs and to track improvement of care. The analysis and monitoring of some triggers is important to prevent AEs. However, it is a labor-intensive method, particularly if the CRs are paper based.

Introduction

Safety is one of the domains of quality in healthcare. Improving the safety of patients is a political priority worldwide, as studies on the safety of patients have drawn attention to the high rates of health care-related harm13. Improving patient safety requires effective and reliable methods to identify and monitor adverse events (AEs) so that learning can take place and improvements can be made.

Even though several methods to detect AEs are available, there is no universally recognized method that reliably provides a comprehensive overview of the extent of the problem. These methods include incident reporting, clinical records (CRs) review and automated extraction using hospital administrative data, for example Patient Safety Indicators (PSI) as developed by the Agency for Healthcare Research and Quality (AHRQ). Incident reporting is the most commonly used method to detect AEs in hospitals, but is based on voluntary reporting. Despite considerable efforts by local hospitals, reporting systems only detect a limited number of AEs4. The effectiveness of automated extraction using hospital administrative data for detecting AEs depends on the accuracy of data compilation. CRs review, as used in the Harvard Medical Practice Study, is very labor intensive, thereby limiting its use4. As a result, health services, governments and researchers have focused on developing harm detection tools.

This paper is one of the first to report the findings of the application of the Global Trigger Tool, developed by the Institute for Healthcare Improvement (IHI), across the whole health system in Sicily. In 2015, the Sicilian Health System adopted IHI GTT5 to assess the number, types and severity levels of AEs.

Methods

IHI GTT

The measurement instrument used in our study is the Italian version of the IHI GTT6. The Italian version was adapted to be appropriate to the regional context7. The triggers are grouped into the same seven categories as the original version (care, medication, surgical, intensive care, obstetric, pediatrics and emergency care); however, changes to some triggers have been introduced. We did not consider triggers and AEs that were present on admission and we added three new triggers: change in procedure anesthesia, duration of surgery greater than 6 hours, and hospital stay greater than five days after delivery7.

Sampling selection

The sampling method followed that recommended by the IHI GTT, with 10 inpatient CRs randomly selected monthly. From the ordered sequence of the numbering of the CRs of the period under evaluation, a CR was selected every 10 (ie 10th, 20th, 30th, 40th, 50th, etc). In the case in which the number of patients discharged during that month is less than 100, we proceed to remove the previously selected CRs and selecting another CR in the same way (one CR every 10). Eligibility criteria were an admission lasting more than 24 hours, and all the administrative data completed. In the Intensive Care Unit (ICU), all patient CRs, discharged during the reference period, were reviewed.

Review team

As per the IHI protocol, each review team was composed of three individuals: two with clinical knowledge and expertise on patient clinical documentation, and a physician whose role was to authenticate the findings and the severity rating of the AEs. The total number of the reviewers was 199 divided into a 71-person team. Where possible, the review team remained consistent over time.

Review process

We excluded triggers and/or events that took place outside the time of the patient admission to the hospital and we considered only triggers and AEs that occurred during hospitalization. The two clinical reviewers audited all the CRs on their own. We used five worksheets: general care, medication, surgical, obstetric and intensive care, with some changes in accordance with the IHI GTT. The CRs were examined following the order of the sections described in the IHI GTT. Limit for review of each patient record was 20 minutes. The “20-minute rule” was applied to all records regardless of size5. The reviewers entered data into a specially developed dedicated IT-platform, developed by our IT team (based on Jawascript HTML and PHP)8

Statistical analysis

For the statistical analysis we used the software SPSS ver. 20. We used it also to develop the Receiver Operating Characteristic (ROC) curve analysis.

Results

From June 2015 to June 2018, 18,008 CRs from 105 wards of 44 Sicilian public hospitals were examined. In this study, we analyzed 14,706 CRs relating to patients discharged from 89 medicine, surgery, obstetrics and intensive care wards. In 5,574 (37.9%) CRs at least one trigger was found. In 7 CRs an AE was detected without a trigger being present. AEs were determined in 1,542 CRs (Table 1). The identification of triggers allowed us to identify corresponding AEs (Table 2).

AEs, adverse events.

This analysis allowed us to highlight how isolated triggers are not always a good indicator of AEs. A Receiver Operating Characteristic (ROC) curve analysis demonstrates that the presence of two triggers in a CR has a high probability of an AE having occurred (Figure 1). In CRs with a high frequency of triggers, a corresponding number of AEs was not always detected. As indicated in Table 3, on the contrary, some triggers were associated with a large number of AEs. Triggers and AEs were analyzed when isolated triggers were identified (Table 4). For example, the isolated trigger C01 (Blood products use) was present in 483 cases, but identified only two AEs, and the trigger M05 (Rising BUN or serum creatinine >2 times the baseline) did not identify any AEs. AEs were classified using the 2009 edition of the WHO International Classification for Patient Safety (ICPS)9, and a clinical classification developed by our group (Table 5).

Discussion

The evaluation of the quality and safety of health systems is difficult, but has become a priority of healthcare funders and organizations. Outcome, management and patient satisfaction indicators are available to measure the different dimensions of health care quality, but reliable measurements of safety have been elusive. Many methodologies and indicators, such as the PSI developed by AHRQ, and the review of health documentation and incident reporting are currently used. The documentation and study of AEs, i.e. where they occur, and the type and degree of harm, is essential to promote specific opportunities for improvement interventions and to evaluate effectiveness of any intervention over time.

The IHI GTT is one methodology proposed to detect and monitor AEs and provide information to implement improvement. At present, compared to other methods, it may be the best methodology to use4. A systematic review reported the use of GTT methodology in 15 countries in 44 hospitals, with 79,004 clinical records examined10. The data are an underestimation, as the report did not include some comprehensive Swedish and Norwegian studies11. Recently, papers have been published in Italy, Austria, China and Russia1216. A critical appraisal of the studies and their results is difficult, as the methodology used is heterogeneous, protocols are often locally adapted to the local context, the populations studied are different, and the skills of the reviewers vary. We adapted the IHI GTT to the local context in Sicily for this study and did not consider triggers and AEs identified at the admission of the patient as well as modifying some triggers. In this study, the triggers were analyzed both when associated with other triggers and when isolated. In both cases the correlation with AEs was analyzed.

Rates of triggers

In this study, 37.9% (n=5,574) of CRs examined had triggers and in 18.9% (n=2,778) an isolated trigger was found. CRs with triggers (n=5,574) are significantly present in surgery wards (n=1,709; 35.4%), medicine wards (n=1,517; 34.3%) and ICU (n=1,672; 84.7%). while CRs with triggers in obstetrics wards are significantly less frequent (n=676; 20.3%). CRs with isolated triggers are more common in medical wards (n=1,085; 23.7%) and rarer in ICU (n=272; 13.7%) (Table 1).

The connection between the number of CRs with triggers and the number of CRs examined is not always reported in the literature and when reported it is not always clear. Xu et al.17 report that during review of 240 clinical records, 51.0% triggers (26/51) were identified 206 times. Mortaro et al.12 report that during review of 1,320 clinical records, a total of 130 triggers were detected.

In general, it would appear that little attention is paid to triggers if they are not related to an AE. Instead, many triggers of the IHI GTT protocol could be considered to be a measure of near misses and potential AEs. These include, decrease of Hb or Ht >25%, readmission within 30 days, transfer to higher level of care, clostridium difficile–positive stool, PTT >100 seconds, INR > 6, glucose < 50 mg/dl, rising BUN or serum creatinine >2 times baseline, blood loss >500 mL (after vaginal delivery) or >1000 mL (Cesarean section), and readmission to ICU.

Rates of AEs

In a systematic review, de Vriess et al.18 reported that in 8 studies that included 74,485 CRs, the median overall incidence of in-hospital AEs was 9.2%. Another systematic review reported 44 hospitals with 79,004 CRs, had an incidence between 7 and 51%10. In the Sicilian public hospitals, 1,542 AEs were detected in 975 clinical records, corresponding to an incidence of 6.6% of CRs examined, and to 17.5% of CRs with triggers. It would appear that the percentage of clinical records with triggers increases with the increase of percentage of CRs examined, compared to the patients discharged, while the percentage of CRs with AEs remains more stable (Figure 2).

Figure 2. Rate n. clinical records (CRs) with trigger and adverse events (EAs) and n. discharged patients, June 2015–June 2018.

ICUs have the highest incidence of AEs, both with respect to CRs examined (30.4%) and those with triggers (35.9%) (Table 1). This could be due to patients being transferred to ICU and the cause of the AE was in another clinical setting. We analyzed the AEs comparing them to the triggers to allow for their identification:

  • Most AEs are associated with general care triggers (n=6,103) (Table 2). If triggers are isolated, AEs are more frequently associated with care triggers (n=80) (Table 4).

  • The triggers related to general care have been identified 7,497 times, with an AE in 6,103 (81.4%).

  • Medications-related triggers have been identified 2,878 times, with an AE in 1,525 (53%).

  • Surgery-elated triggers have been identified 323 times, with an AE in 148 (45.8%).

  • Obstetrics-related triggers have been identified 492 times, with an AE in 61 (12.4%).

  • Intensive-care-related triggers have been identified 1,817 times with an AE in 1,924 (i.e. it is very common for triggers to identify more AEs in the same patient) (Table 1 and Table 2).

However, if isolated triggers are considered, the intensive-care-related triggers were detected 46 times and they were correlated with only one AE (Table 4). This observation suggests that isolated triggers rarely allow to identify an AE and that the strength of the IHI’s GTT methodology is linked to the association of triggers. It is evident that the detection of many triggers in a CR is associated with a high probability of AEs. The analysis of the ROC curve (Figure 1) shows that it is sufficient to detect two triggers in a CR because it can be almost certain that in that CR there may be an AE.

We have classified the AEs using the ICPS 2009 classification and a clinical classification, developed by our group. In both classifications, hospital acquired infections are the most frequent AEs present (Table 5), observed in the ICU in 625 clinical records (84.3%). Surgical complications (n=175) were observed in 55.9% (n=99) in ICU, i.e. they were AEs in patients undergoing surgery and then transferred to ICU due to the onset of a complication. In 44.6% (n=80), the AEs are represented by hemorrhagic complications (intra- and post-operative hemorrhages or hematomas). Pressure ulcer lesions were detected in 172 cases, usually in the ICUs (n=112 - 65.1%). Also, the complications from procedures (n=109) were observed mainly in the ICU (n=78; 71.5%). In total, 33 complications from procedures are related to orotracheal intubation, 22 at central venous catheter, and 10 at childbirth analgesia. The complications of child birth (n= 47) were represented more frequently in 59.5% (n=28) by bleeding and in 29.8% (n=14) by lacerations.

Limitations

Our study has some several limitations. The first concerns the inter-rater reliability assessment of review teams that is not available. The second limitation is the underlying quality of CRs, which may have affected the results. However, all reviewers received the same training and each team followed the same protocols to ensure reliability.

Conclusion

The Global Trigger Tool is an effective method to identify AEs and track improvement of care. It provides to clinical teams an understanding of the patient safety issues that are present in their clinical area, as well as opportunities to improve. With active involvement of clinical teams, it places patient safety in the centre of clinical activity and fosters a culture of safety. It also provides an effective way to assess the quality of the clinical records. The drawback is that the process is labor intensive, particularly if the clinical records are paper based. The introduction of electronic medical records would allow a quicker process with the automation of the identification of triggers and the possibility to link triggers together in the identification of adverse events and near misses, especially where there has been more than one trigger19. Finally, we conclude that the analysis and monitoring of some triggers, as potential indicators of near misses, is important to prevent adverse events.

Ethical considerations

Since the data used in this study was gathered during routine practice and is used for analysis of hospital procedures, no ethical approval was obtained. Every patient gave written informed consent on admission to hospital for the use of their data for scientific research. This consent is the "Information on the processing of personal data" with reference to the Italian law n. 196/2003 and Regulation (EU) 2016/679 of the European Parliament and of the Council of 27 April 2016 (UE).
