The rate of iatrogenic injuries in surgical patients appears resistant to multiple interventions: what can we learn from aviation safety?

BACKGROUND

This project analyses all iatrogenic injuries from our department over the last decade and tracks their rate against several interventions.

METHODS

All patients who sustained an iatrogenic injury between 2012 and 2022 were reviewed.

RESULTS

A total of 946 iatrogenic injuries occurred in 731 patients. Sixty per cent of these patients were male; the median age was 39 years. Of 946 injuries, 574 (60.7%) occurred during an operation, and 372 (39.3%) were not related to an operation. Of the operative injuries 412 (71.8%) were enteric injuries. Of the 372 non-operative iatrogenic injuries 304 (82%) were due to indwelling devices (ID), and 34 (10%) occurred during flexible endoscopy. Fifty-five per cent of the injuries due to ID were due to central venous catheters (CVC) and urinary catheters (UC). CVC contributed toward 31% of all non-operation related iatrogenic injuries. One in 54 admissions (946/51 178) and one in 47 (574 /27 342) patients undergoing an operation sustained an iatrogenic injury. The annual rate of iatrogenic injuries did not decrease over the decade despite a multifaceted approach to reduce them. Interventions included electronic database development, procedural standardisation, and checklist implementation.

CONCLUSION

Despite multiple interventions over a decade, our rate of iatrogenic injury remains constant. Ongoing multifaceted efforts to reduce this rate must focus on engendering a culture of safety at all levels of healthcare if we hope to match the enviable safety record of the aeronautics industry.

Adverse events associated with the use of indwelling devices in surgical patients

BACKGROUND

Indwelling devices (IDs) are ubiquitous in modern healthcare and may often be associated with morbidity. This paper investigates adverse events related to IDs in surgical patients, which are generally placed into patients either to administer therapy, manage outputs or for specific therapeutic benefit.

METHODS

A retrospective electronic database-based assessment of all adverse events relating to IDs was undertaken from December 2012 to August 2021. All events were categorised by device type, event type, and event severity.

RESULTS

A total of 11 130 morbidities were captured over the study period. Of those, 2 195 entries pertained to an ID with 2 402 reported adverse events affecting 1 592 patients. Two-thirds occurred in males and injuries occurred in patients age ranging from eight days to 93 years, with an average age of 36 years. The most frequently implicated devices were surgical drains (including intercostal chest drains), accounting for 491 (20.44%) of adverse events. Central venous catheters (CVCs) and intravenous cannulae were involved in 374 (15.57%) and 332 (13.83%) events, respectively. Unplanned removal (346, 13.91%), output not measured (319, 12.82%), injury (314, 12.62%), and blockage (279, 11.21%) were the most common error types. The majority of adverse events were considered minor, however 27 (1.1%) patients experienced organ dysfunction as a result of an ID-related adverse event, and seven (0.3%) died.

CONCLUSIONS

Morbidity related to IDs in surgical patients is a relatively frequent occurrence. Standardisation of ID insertion and care, staff education, and improvements in communication have been identified as the most important strategies by which we can limit error-associated morbidity in patients with IDs.

Transdiaphragmatic pericardial washout post penetrating cardiac injury found incidentally at diagnostic laparoscopy

A 22-year-old male presented following a precordial stab. He was haemodynamically and metabolically normal. Initial investigations did not reveal pericardial fluid or haemothorax. At diagnostic laparoscopy, we encountered haemoperitoneum and a diaphragmatic injury through which the heart was visible. After pericardial washout, laparoscopic repair was effected. This case highlights a potential problem with extended focused assessment with sonography in trauma (eFAST) in that it will only be positive if there is an accumulation of pericardial fluid. It also confirms the utility of diagnostic laparoscopy for penetrating left thoracoabdominal injuries and shows that principles of open surgery can be safely applied laparoscopically in select patients.

Psychiatric morbidity in medical and surgical patients evacuated from the Persian Gulf War

Acute treatment records of all medical and surgical patients evacuated to Walter Reed Army Medical Center in Washington, D.C., from the Persian Gulf theater (N = 161) were examined to better understand the relationship of injury to psychiatric symptoms. A total of 110 (68 percent) sustained a traumatic injury. They were significantly more likely to have an axis I disorder or psychiatric symptoms of concern than participants in the Persian Gulf War who did not sustain traumatic injuries but who were evacuated for medical conditions. The results indicate that traumatically injured veterans are at greater risk of psychiatric symptoms than veterans who are not injured and that they should be referred for psychiatric evaluation.
