Long-term Health Outcomes of New Persistent Opioid Use After Surgery Among Medicare Beneficiaries.

OBJECTIVE: We examined long-term health outcomes associated with new persistent opioid use after surgery and hypothesized that patients with new persistent opioid use would have poorer overall health outcomes compared with those who did not develop new persistent opioid use after surgery. BACKGROUND: New persistent opioid use is a common surgical complication. Long-term opioid use increases risk of mortality, fractures, and falls; however, less is known about health care utilization among older adults with new persistent opioid use after surgical care. METHODS: We analyzed claims from a 20% national sample of Medicare beneficiaries ≥65 years undergoing surgery between January 1, 2009, and June 30, 2019. We estimated associations between new persistent use and subsequent health events between 6 and 12 months after surgery, including mortality, serious fall/fall-related injury, and respiratory or opioid/pain-related readmission/emergency department (ED) visits using a Cox proportional hazards model to estimate mortality and multivariable logistic regression for the remaining outcomes, adjusting for demographic/clinical characteristics. Our primary outcome was mortality within 6 to 12 months after surgery. Secondary outcomes included falls and readmissions or ED visits (respiratory, pain related/opioid related) within 6 to 12 months after surgery. RESULTS: Of 229,898 patients, 6874 (3.0%) developed new persistent opioid use. Compared with patients who did not develop new persistent opioid use, patients with new persistent opioid use had a higher risk of mortality (hazard ratio 3.44, CI, 2.99-3.96), falls [adjusted odds ratio (aOR): 1.21, 95% CI, 1.05-1.39], and respiratory-related (aOR: 1.67, 95% CI, 1.49-1.86) or pain-related/opioid-related (aOR: 1.68, 95% CI, 1.55-1.82) readmissions/ED visits. CONCLUSIONS: New persistent opioid use after surgery is associated with increased mortality and poorer health outcomes after surgery. Although the mechanisms that underlie this risk are not clear, persistent opioid use may also be a marker for greater morbidity requiring more care in the late postoperative period. Increased awareness of individuals at risk for new persistent use after surgery and close follow-up in the late postoperative period is critical to mitigate the harms associated with new persistent use.

Dental Opioid Prescriptions and Overdose Risk in Patients and Their Families.

INTRODUCTION: It is unknown whether dental opioid prescriptions are associated with opioid overdose in patients or their family members, who may have access to patients' opioids. METHODS: During July-October 2020, the 2011-2018 IBM MarketScan Dental, IBM MarketScan Commercial, and Medicaid Multi-State Databases were analyzed. Two analyses were conducted. In the patient analysis, dental procedures for privately and publicly insured patients aged 13-64 years were identified. The exposure was ≥1 initial prescription (dispensed opioid prescription within 3 days of the procedure). The association between the exposure and ≥1 overdose within 90 days of the procedure was evaluated using logistic regression. In the family analysis, procedures for privately insured patients in family plans were identified. The association between the exposure and ≥1 overdose in a family member within 90 days was evaluated using logistic regression. In both analyses, the average marginal effect of the exposure was calculated, representing the change in the probability of the outcome if all versus if no procedures were associated with ≥1 initial prescription. RESULTS: The patient analysis included 8,544,098 procedures. When ≥1 initial prescription did and did not occur, the 90-day risk of overdose was 5.8 versus 2.2 per 10,000 procedures (average marginal effect=1.5, 95% CI=1.2, 1.8). The family analysis included 3,461,469 procedures. When ≥1 initial prescription did and did not occur, the 90-day risk of overdose in a family member was 1.7 versus 1.0 per 10,000 procedures (average marginal effect=0.4, 95% CI=0.1, 0.7). CONCLUSIONS: Findings further highlight the importance of avoiding unnecessary dental opioid prescribing.

Coordination of Care Is Associated With Survival and Health Care Utilization in a Population-Based Study of Patients With Cirrhosis.

BACKGROUND & AIMS: Improving care coordination for patients with high-intensity specialty care needs, such as cirrhosis, can increase quality of healthcare and reduce utilization. We examined the relationship between care concentration and risk of hospitalization for patients with cirrhosis. METHODS: We performed a retrospective cohort study of 26,006 Medicare enrollees with cirrhosis with more than 4 outpatient visits over 180 days. We collected data on 2 validated measures of care concentration: the usual provider of care (UPC) index, a measure of the proportion of a patient's total visits that is with their most regularly seen provider, and the continuity of care (COC) index, a measure of care density and dispersion. Both use a scale of 0 to 1. Time to death or liver transplantation was evaluated using a multivariable Cox proportional hazards model. Hospital days and 30-day readmissions per person-year were evaluated in negative binomial models. RESULTS: The median COC score was 0.40 (interquartile range, 0.26-0.60) and the median UPC was 0.60 (interquartile range, 0.50-0.80). Increasing care concentration (based on COC and UPC index scores) were associated with increased mortality and hospitalization. The highest 25th percentile of COC and UPC scores were associated with adjusted hazard ratios for mortality of 1.20 (95% CI, 1.10-1.31) and 1.14 (95% CI, 1.06-1.24), adjusted incidence rate ratios for hospital days of 1.12 (95% CI, 1.02-1.23) and 1.10 (95% CI, 1.01-1.20), and adjusted incidence rate ratios for readmissions of 1.19 (95% CI, 1.06-1.34) and 1.12 (95% CI, 1.00-1.25), respectively. CONCLUSIONS: Based on a study of Medicare enrollees, care concentration is low among patients with cirrhosis. However, increased concentration is associated with increased mortality and increased healthcare utilization. These data indicate that, to optimize outcomes for persons with cirrhosis, team-based care might be necessary.

Statewide Prehabilitation Program and Episode Payment in Medicare Beneficiaries.

BACKGROUND: Prehabilitation has been shown to improve postoperative outcomes in a variety of patient populations undergoing major operations. The feasibility, generalizability, and value of broad implementation of prehabilitation outside the research environment are unknown. METHODS: Medicare claims data from 2014 to 2017 were used to conduct a multicenter (21 Michigan hospitals) pragmatic cohort study. Patients and controls were followed for the duration of their index surgical hospitalization and for 90 days postoperatively. Medicare beneficiaries older than 18 years who underwent inpatient surgical procedures at a participating hospital during the study time period were eligible for inclusion. The prehabilitation program involved a home-based walking program with supplementary education on nutrition, smoking cessation, and psychological preparation for surgical procedure. Data were analyzed with an intention-to-treat approach using t-tests and Wilcoxon rank sum tests. Propensity score matching used comorbidities and demographic factors to match controls to patients in a 2:1 manner with an exact match required for operation type. RESULTS: Patients (n = 523) and controls (n = 1,046) had no significant differences in demographic factors or comorbidities. Patients had significantly shorter median hospital length of stay (6 vs 7 days; p < 0.01) than controls and were more likely to be discharged to home (65.6% vs 57.0%, p < 0.01). Total episode payments were significantly lower for patients compared with controls ($31,641 vs $34,837; p = 0.04). Patients had significantly lower post-acute care payments for skilled nursing facility ($941 vs $1,566; p = 0.02) and home health ($829 vs $960; p = 0.03) services. CONCLUSIONS: Participation in a prehabilitation program in Michigan was associated with shorter length of stay and lower total episode payments after operation. Payers and hospitals should invest in the implementation of simple home-based prehabilitation programs.

Association Between Long-term Opioid Use in Family Members and Persistent Opioid Use After Surgery Among Adolescents and Young Adults.

Importance: Prior studies have found a substantial risk of persistent opioid use among adolescents and young adults undergoing surgical and dental procedures. It is unknown whether family-level factors, such as long-term opioid use in family members, is associated with persistent opioid use. Objective: To determine whether long-term opioid use in family members is associated with persistent opioid use among opioid-naive adolescents and young adults undergoing surgical and dental procedures. Design, Setting, and Participants: This retrospective cohort study used data from a commercial insurance claims database for January 1, 2010, to June 30, 2016, to study 346 251 opioid-naive patients aged 13 to 21 years who underwent 1 of 11 surgical and dental procedures and who were dependents on a family insurance plan. Exposures: Long-term opioid use in family members, defined as having 1 or more family members who (1) filled opioid prescriptions totaling a 120 days' supply or more during the 12 months before the procedure date or (2) filled 3 or more opioid prescriptions in the 90 days before the procedure date. Main Outcomes and Measures: The main outcome measure was persistent opioid use, defined as 1 or more postoperative prescription opioid fills between 91 and 180 days among patients with an initial opioid prescription fill. Generalized estimating equations with robust SEs clustered at the family level were used to model persistent opioid use as a function of long-term opioid use among family members, controlling for procedure, total morphine milligram equivalents of the initial fill, and patient and family characteristics. Results: A total of 346 251 patients (mean [SD] age, 17.0 [2.3] years; 175 541 [50.7%] female) were studied. Among these patients, 257 085 (74.3%) had an initial opioid fill. Among patients with an initial opioid fill, 11 016 (4.3%) had long-term opioid use in a family member. Persistent opioid use occurred in 453 patients (4.1%) with long-term opioid use in a family member compared with 5940 patients (2.4%) without long-term opioid use in a family member (adjusted odds ratio, 1.54; 95% CI, 1.39-1.71). Conclusion and Relevance: The findings suggest that long-term opioid use among family members is associated with persistent opioid use among opioid-naive adolescents and young adults undergoing surgical and dental procedures. Physicians should screen young patients for long-term opioid use in their families and implement heightened efforts to prevent opioid dependence among patients with this important risk factor.

Targeting Value-Driven Quality Improvement for Laparoscopic Cholecystectomy in Michigan.

OBJECTIVE: The purpose of this study was to evaluate complete episode expenditures for laparoscopic cholecystectomy, a common and lower-risk operation, to characterize novel targets for value-based quality improvement. SUMMARY BACKGROUND DATA: Despite enthusiasm for improving the overall value of surgical care, most efforts have focused on high-risk inpatient surgery. METHODS: We identified 19,213 patients undergoing elective laparoscopic cholecystectomy from 2012 to 2015 using data from Medicare and a large private payer. We calculated price-standardized payments for the entire surgical episode of care and stratified patients by surgeon. We used linear regression to risk- and reliability-adjusted expenditures for patient characteristics, diagnoses, and the use of additional procedures. RESULTS: Fully adjusted total episode costs varied 2.4-fold across surgeons ($7922-$17,500). After grouping surgeons by adjusted total episode payments, each component of the total episode was more expensive for patients treated by the most expensive versus the least expensive quartile of surgeons. For example, payments for physician services were higher for the most expensive surgeons [$1932, 95% confidence interval (CI) $1844-$2021] compared to least expensive surgeons ($1592, 95% CI $1450-$1701, P < 0.01). Overall differences were driven by higher rates of complications (10% vs. 5%) and readmissions (14% vs. 8%), and lower rates of ambulatory procedures (77% vs. 56%) for surgeons with the highest versus lowest expenditures. Projections showed that a 10% increase ambulatory operations would yield $3.6 million in annual savings for beneficiaries. CONCLUSIONS: Episode payments for laparoscopic cholecystectomy vary widely across surgeons. Although improvements in several domains would reduce expenditures, efforts to expand ambulatory surgical practices may result in the largest savings to beneficiaries in Michigan.

The Michigan Surgical Home and Optimization Program is a scalable model to improve care and reduce costs.

BACKGROUND: The Michigan Surgical Home and Optimization Program is a structured, home-based, preoperative training program targeting physical, nutritional, and psychological guidance. The purpose of this study was to determine if participation in this program was associated with reduced hospital duration of stay and health care costs. METHODS: We conducted a retrospective, single center, cohort study evaluating patients who participated in the Michigan Surgical Home and Optimization Program and subsequently underwent major elective general and thoracic operative care between June 2014 and December 2015. Propensity score matching was used to match program participants to a control group who underwent operative care prior to program implementation. Primary outcome measures were hospital duration of stay and payer costs. Multivariate regression was used to determine the covariate-adjusted effect of program participation. RESULTS: A total of 641 patients participated in the program; 82% were actively engaged in the program, recording physical activity at least 3 times per week for the majority of the program; 182 patients were propensity matched to patients who underwent operative care prior to program implementation. Multivariate analysis demonstrated that participation in the Michigan Surgical Home and Optimization Program was associated with a 31% reduction in hospital duration of stay (P < .001) and 28% lower total costs (P < .001) after adjusting for covariates. CONCLUSION: A home-based, preoperative training program decreased hospital duration of stay, lowered costs of care, and was well accepted by patients. Further efforts will focus on broader implementation and linking participation to postoperative complications and rigorous patient-reported outcomes.
