The Incidence and Preventability of Adverse Events in Older Acutely Admitted Patients: A Longitudinal Study With 4292 Patient Records

Fatal Adverse Events in Femoral Neck Fracture Patients Undergoing Hemiarthroplasty or Total Hip Arthroplasty-A Retrospective Record Review Study in a Nationwide Sample of Deceased Patients

OBJECTIVES

Patient safety is a core component of quality of hospital care and measurable through adverse event (AE) rates. A high-risk group are femoral neck fracture patients. The Dutch clinical guideline states that the treatment of choice is cemented total hip arthroplasty (THA) or hemiarthroplasty (HA). We aimed to identify the prevalence of AEs related to THA/HA in a sample of patients who died in the hospital.

METHODS

We used data of a nationwide retrospective record review study. Records were systematically reviewed for AEs, preventability and contribution to the patient's death. We drew a subsample of THA/HA AEs and analyzed these cases.

RESULTS

Of the 2998 reviewed records, 38 patients underwent THA/HA, of whom 24 patients suffered 25 AEs (prevalence = 68.1%; 95% confidence interval, 51.4-81.2), and 24 contributed to death. Patients with a THA/HA AE were of high age (median = 82.5 y) and had severe comorbidity (Charlson score ≥5). The majority of THA/HA AEs had a patient-related cause and was considered partly preventable. Examples of suggested actions that might have prevented the AEs: refraining from surgery, adhering to medication guidelines, uncemented procedures, comprehensive presurgical geriatric assessment, and better postsurgical monitoring.

DISCUSSION

Our study shows a high prevalence of (fatal) adverse events in patients undergoing THA/HA. This seems particularly valid for cemented implants in frail old patients, indicating room for improvement of patient safety in this group. Therefore, we recommend physicians to engage in comprehensive shared decision making with these patients and decide on a treatment fitting to a patient's preexisting health status, preferences, and values.

Gender differences in medical errors among older patients and inequalities in medical compensation compared with younger adults

Background

Despite growing evidence focusing on health inequalities in older adults, inequalities in medical compensation compared with younger adults and gender disparities of medical errors among older patients have received little attention. This study aimed to disclose the aforementioned inequalities and examine the disparities in medical errors among older patients.

Methods

First, available litigation documents were searched on "China Judgment Online" using keywords including medical errors. Second, we compiled a database with 5,072 disputes. After using systematic random sampling to retain half of the data, we removed 549 unrelated cases. According to the age, we identified 424 and 1,563 cases related to older and younger patients, respectively. Then, we hired two frontline physicians to review the documents and independently judge the medical errors and specialties involved. A third physician further considered the divergent results. Finally, we compared the medical compensation between older and younger groups and medical errors and specialties among older patients.

Results

Older patients experienced different medical errors in divergent specialties. The medical error rate of male older patients was over 4% higher than that of females in the departments of general surgery and emergency. Female older patients were prone to adverse events in respiratory medicine departments and primary care institutes. The incidence of insufficient implementation of consent obligation among male older patients was 5.18% higher than that of females. However, females were more likely to suffer adverse events at the stages of diagnosis, therapy, and surgical operation. The total amount of medical compensation obtained by younger patients was 41.47% higher than that of older patients.

Conclusions

Except for the common medical errors and departments involved, additional attention should be paid to older patients of different genders according to the incidence of medical errors. Setting up the department of geriatrics or specialist hospitals is also an important alternative to improve patient safety for older people. Furthermore, there may be inequality in medical compensation in older patients due to the tort liability law of China.
