“That really shouldn't have happened”: People with aphasia and their spouses narrate adverse events in hospital

Up to 50% of adverse events that occur in hospitals are preventable. Language barriers and disabilities that affect communication have been shown to decrease quality of care. We sought to assess whether communication problems are associated with an increased risk of preventable adverse events. We randomly selected 20 general hospitals in the province of Quebec with at least 1500 annual admissions. Of the 145,672 admissions to the selected hospitals in 2000/01, we randomly selected and reviewed 2355 charts of patients aged 18 years or older. Reviewers abstracted patient characteristics, including communication problems, and details of hospital admission, and assessed the cause and preventability of identified adverse events. The primary outcome was adverse events. Of 217 adverse events, 63 (29%) were judged to be preventable, for an overall population rate of 2.7% (95% confidence interval [CI] 2.1%-3.4%). We found that patients with preventable adverse events were significantly more likely than those without such events to have a communication problem (odds ratio [OR] 3.00; 95% CI 1.43-6.27) or a psychiatric disorder (OR 2.35; 95% CI 1.09-5.05). Patients who were admitted urgently were significantly more likely than patients whose admissions were elective to experience an event (OR 1.64, 95% CI 1.07-2.52). Preventable adverse events were mainly due to drug errors (40%) or poor clinical management (32%). We found that patients with communication problems were more likely than patients without these problems to experience multiple preventable adverse events (46% v. 20%; p = 0.05). Patients with communication problems appeared to be at highest risk for preventable adverse events. Interventions to reduce the risk for these patients need to be developed and evaluated.

Hospitals routinely survey patients about the quality of care they receive, but little is known about whether patient interviews can detect adverse events that medical record reviews do not. To compare adverse events reported in postdischarge patient interviews with adverse events detected by medical record review. Random sample survey. Massachusetts, 2003. Recently hospitalized adults. By using parallel methods, physicians reviewed postdischarge interviews and medical records to classify hospital adverse events. Among 998 study patients, 23% had at least 1 adverse event detected by an interview and 11% had at least 1 adverse event identified by record review. The kappa statistic showed relatively poor agreement between interviews and medical records for occurrence of any type of adverse event (kappa = 0.20 [95% CI, 0.03 to 0.27]) and somewhat better agreement between interviews and medical records for life-threatening or serious events (kappa = 0.33 [CI, 0.20 to 0.45]). Record review identified 11 serious, preventable events (1.1% of patients). Interviews identified an additional 21 serious and preventable events that were not documented in the medical record, including 12 predischarge events and 9 postdischarge events, in which symptoms occurred after the patient left the hospital. Patients had to be healthy enough to be interviewed. Delay in reaching patients (6 to 12 months after discharge) may have resulted in poor recall of events during the hospital stay. Patients report many events that are not documented in the medical record; some are serious and preventable. Hospitals should consider monitoring patient safety by adding questions about adverse events to postdischarge interviews.
