BACKGROUND: Despite increasing numbers of older adults undergoing surgery and the known risks of opioids, little is known about the potential association between opioid prescribing and serious falls and fall-related injuries after surgery. OBJECTIVE: To determine the incidence and risk factors of serious falls and fall-related injuries after elective, outpatient surgery. DESIGN: Retrospective cohort study of 20% national sample of Medicare claims among beneficiaries ≥ 65 years of age with Medicare Part D claims and who underwent elective outpatient surgery from January 1, 2009, through December 31, 2014. PARTICIPANTS: Opioid-naïve patients ≥ 65 years undergoing elective, minor, outpatient surgical procedures. The exposure was opioid prescription fills in the perioperative period (i.e., 30 days before up until 3 days after surgery) converted to total oral morphine equivalents (OME) over a period 30 days prior to and 30 days after surgery. MAIN MEASURES: Serious falls and fall-related injuries within 30 days after surgery, examined through Poisson regression analysis with reported fall and fall-related injury rates adjusted for potential confounders. KEY RESULTS: Among 44,247 opioid-naïve surgical patients, 76.3% filled an opioid prescription in the perioperative period. Overall, 0.62% of patients suffered a serious fall or fall-related injury within 30 days after surgery. Risk factors for serious falls or fall-related injuries after surgery included older age (80-84 years: RR 1.64, 95% CI 1.12-2.40; 85 years and older: RR 1.81, 95% CI 1.25-2.86), female sex (RR 3.04, 95% CI 2.29-4.05), Medicaid eligibility (RR 1.63, 95% CI 1.17-2.26), and higher amounts of opioids filled following surgery (≥ 225 OME: RR 2.29, 95% CI 1.72-3.07). CONCLUSIONS: Serious falls after elective, outpatient surgery are uncommon, but correlated with age, sex, Medicaid eligibility, and the amount of opioids filled in the perioperative period. Judicious prescribing of opioids after surgery is paramount and is an opportunity to improve the safety of surgical care among older individuals.
Objective: To examine differences in rates of elective surgery, postoperative mortality, and readmission by pre-existing cognitive status among Medicare beneficiaries undergoing surgery. Background: MCI is common among older adults, but the impact of MCI on surgical outcomes is understudied. Methods: We conducted a retrospective cohort study of individuals ≥65 who underwent surgery between 2001 and 2015 using data from the nationally-representative Health and Retirement Study linked with Medicare claims. Cognitive status was assessed by the modified telephone interview for cognitive status score and categorized as normal cognition (score: 12-27), MCI (7-11), and dementia ( < 7). Outcomes were 30-and 90-day postoperative mortality and readmissions. We used Cox proportional hazard models to estimate the risk of each outcome by cognition, adjusting for patient characteristics. Results: In 6,590 patients, 69.9% had normal cognition, 20.1% had MCI, and 9.9% had dementia. Patients with MCI (79.9%) and dementia (73.6%) were less likely to undergo elective surgery than patients with normal cognition (85.9%). Patients with MCI had similar postoperative mortality and readmissions rates as patients with normal cognition. However, patients with dementia had significantly higher postoperative 90-day mortality (5.2% vs 8.4%, P = 0.002) and readmission rates (13.9% vs 17.3%, P = 0.038). Conclusion: Patients with self-reported MCI are less likely to undergo elective surgery but have similar postoperative outcomes compared with patients with normal cognition. Despite the variability of defining MCI, our findings suggest that MCI may not confer additional risk for older individuals undergoing surgery, and should not be a barrier for surgical care.
Background: Older adults with mild cognitive impairment (MCI) receive fewer guideline-concordant treatments for multiple health conditions than those with normal cognition. Reasons for this disparity are unclear. Objective: To better understand this disparity, we describe physician understanding and experience with patient MCI, particularly physician identification of MCI, ability to distinguish between MCI and dementia, and perspectives on education and training in MCI and dementia. Methods: As part of a mixed-methods study assessing the influence of patient MCI on physician recommendations for acute myocardial infraction and stroke treatments, we conducted a descriptive qualitative study using semi-structured interviews of physicians from three specialties. Key question topics included participants’ identification of MCI, impressions of MCI and dementia awareness within their practice specialty, and perspectives on training and education in MCI. Results: The study included 22 physicians (8 cardiologists, 7 neurologists, and 7 internists). We identified two primary themes: There is 1) a lack of adequate understanding of the distinction between MCI and dementia; and 2) variation in physician approaches to identifying whether an older adult has MCI. Conclusion: These findings suggest that physicians have a poor understanding of MCI. Our results suggest that interventions that improve physician knowledge of MCI are needed.
Background: Older patients with mild cognitive impairment (MCI) should receive evidence-based treatments when clinically indicated. However, patients with MCI appear less likely than cognitively normal patients to receive evidence-based treatments. Objective: To explore the influence of a patient’s MCI diagnosis on physician decision-making. Methods: Qualitative study of 18 physicians from cardiology, neurology, and internal medicine using semi-structured interviews. We sought to understand whether and how a patient’s having MCI has influenced physicians’ decisions about five categories of treatments or tests (surgery, invasive tests, non-invasive tests, rehabilitation, and preventive medication). We used qualitative content analysis to identify the unifying and recurrent themes. Results: Most physician participants described MCI as influencing their recommendations for at least one treatment or test. We identified two major themes as factors that influenced physician recommendations in patients with MCI: Physicians assume that MCI patients’ decreased cognitive ability will impact treatment; and physicians assume that MCI patients have poor health status and physical functioning that will impact treatment. These two themes were representative of physician beliefs that MCI patients have impaired independent decision-making, inability to adhere to treatment, inability to communicate treatment preferences, and increased risk and burden from treatment. Conclusion: A patient’s MCI diagnosis influences physician decision-making for treatment. Some physician assumptions about patients with MCI were not evidence-based. This phenomenon potentially explains why many patients with MCI get fewer effective treatments or tests than cognitively normal patients. Interventions that improve how physicians understand MCI and make decisions for treatments in patients with MCI are needed.
