Don't chase the adenoma: A probabilistic approach to imaging before parathyroidectomy.

BACKGROUND: Preoperative imaging before parathyroidectomy can localize adenomas and reduce unnecessary bilateral neck explorations. We hypothesized that (1) the utility of preoperative imaging varies substantially depending on the preoperative probability of having adenoma(s) and (2) that a selective imaging approach based on this probability could avoid unnecessary patient costs and radiation. METHODS: We analyzed 3,577 patients who underwent parathyroidectomy for primary hyperparathyroidism from 2001 to 2022. The predicted probability of patients having single or double adenoma versus hyperplasia was estimated using logistic regression. We then estimated the relationship between the predicted probability of single/double adenoma and the likelihood that sestamibi or 4-dimensional computed tomography was helpful for operative planning. Current Medicare costs and published data on radiation dosing were used to calculate costs and radiation exposure from non-helpful imaging. RESULTS: The mean age was 62 ± 13 years; 78% were women. Adenomas were associated with higher mean calcium (11.2 ± 0.74 mg/dL) and parathyroid hormone levels (140.6 ± 94 pg/mL) than hyperplasia (9.8 ± 0.52 mg/dL and 81.4 ± 66 pg/mL). The probability that imaging helped with operative planning increased from 12% to 65%, as the predicted probability of adenoma increased from 30% to 90%. For every 10,000 patients, a selective approach to imaging that considered the preoperative probability of having adenomas could save patients up to $3.4 million and >239,000 millisieverts of radiation. CONCLUSION: Rather than imaging all patients with primary hyperparathyroidism, a selective strategy that considers the probability of having adenomas could reduce costs and avoid excess radiation exposure.

The risks of failed nonoperative management of appendicitis in older adults.

BACKGROUND: The consequences of failed nonoperative management of appendicitis in older patients have not been described. METHODS: We used the 2004-2017 National Inpatient Sample to identify acute appendicitis patients managed nonoperatively (<65 years old: 32,469; ≥65 years old: 11,265). Outcomes included morbidity, length of stay (LOS), inpatient costs, and discharge to skilled facilities. Differences were estimated using propensity scores. RESULTS: For patients <65, nonoperative failure was associated with increased morbidity (7 â€‹% [95 â€‹% CI 6.9 â€‹%-8.1 â€‹%]), LOS (3 day [95 â€‹% CI 3-4]), costs ($9015 [95 â€‹% CI $8216- $9446]), and discharges to skilled facilities (1 â€‹% [95 â€‹% CI 0.9 â€‹%-1.6 â€‹%]) compared to successful nonoperative treatment. Patients ≥65 had differences in morbidity (14 â€‹% [95 â€‹% CI 13.6 â€‹%-16.2 â€‹%]), LOS (6 days [95 â€‹% CI 5-6]), costs ($15,964 [95 â€‹% CI $15,181- $17,708]), and discharges to skilled facilities (12 â€‹% [95 â€‹% CI: 10.0 â€‹%-13.3]) compared to nonoperative success. CONCLUSIONS: Nonoperative management of appendicitis should be approached cautiously for older adults.

Is nonoperative management of appendicitis safe and effective in multi-morbid patients?

BACKGROUND: The purpose of this study was to (1) compare post-treatment outcomes of operative and nonoperative management of acute appendicitis in multi-morbid patients and (2) evaluate the generalizability of prior clinical trials by determining whether outcomes differ in multi-morbid patients compared to the young and healthy patients who resemble prior clinical trial participants. METHODS: We conducted a retrospective cohort study using the National Inpatient Sample from 2004 to 2017. We included 368,537 patients with acute, uncomplicated appendicitis who were classified as having 0 or 2+ comorbidities. We compared inpatient morbidity, mortality, length of stay, and costs using propensity scores. Unmeasured confounding was addressed with probabilistic sensitivity analysis. RESULTS: Overall, 5% of patients without comorbidities were treated nonoperatively versus 20% of multi-morbid patients. Compared to surgery, nonoperative management was associated with a 3.5% decrease in complications (95% confidence interval 3%-4%) for multi-morbid patients, but there was no significant difference for patients without comorbidity. However, nonoperative management was associated with a 1.5% increase in mortality for multimorbid patients (95% confidence interval 1.3%-1.7%). Costs and length of stay were lower for all patients treated with surgery. Probabilistic sensitivity analysis showed that results were robust to the effects of unmeasured confounding. CONCLUSION: Our results raise concerns about the generalizability of clinical trials that compared nonoperative and operative management of appendicitis because (1) those trials enrolled mostly young and healthy patients, and (2) results in multi-morbid patients differ from outcomes in younger and healthier patients.

Comparison of Postoperative Outcomes of Laparoscopic vs Open Inguinal Hernia Repair.

Importance: Advocates of laparoscopic surgery argue that all inguinal hernias, including initial and unilateral ones, should be repaired laparoscopically. Prior work suggests outcomes of open repair are improved by using local rather than general anesthesia, but no prior studies have compared laparoscopic surgery with open repair under local anesthesia. Objective: To evaluate postoperative outcomes of open inguinal hernia repair under general or local anesthesia compared with laparoscopic repair. Design, Setting, and Participants: This retrospective cohort study identified 107 073 patients in the Veterans Affairs Surgical Quality Improvement Program database who underwent unilateral initial inguinal hernia repair from 1998 to 2019. Data were analyzed from October 2021 to March 2022. Exposures: Patients were divided into 3 groups for comparison: (1) open repair with local anesthesia (n = 22 333), (2) open repair with general anesthesia (n = 75 104), and (3) laparoscopic repair with general anesthesia (n = 9636). Main Outcomes and Measures: Operative time and postoperative morbidity were compared using quantile regression and inverse probability propensity weighting. A 2-stage least-squares regression and probabilistic sensitivity analysis was used to quantify and address bias from unmeasured confounding in this observational study. Results: Of 107 073 included patients, 106 529 (99.5%) were men, and the median (IQR) age was 63 (55-71) years. Compared with open repair with general anesthesia, laparoscopic repair was associated with a nonsignificant 0.15% (95% CI, -0.39 to 0.09; P = .22) reduction in postoperative complications. There was no significant difference in complications between laparoscopic surgery and open repair with local anesthesia (-0.05%; 95% CI, -0.34 to 0.28; P = .70). Operative time was similar for the laparoscopic and open general anesthesia groups (4.31 minutes; 95% CI, 0.45-8.57; P = .048), but operative times were significantly longer for laparoscopic compared with open repair under local anesthesia (10.42 minutes; 95% CI, 5.80-15.05; P < .001). Sensitivity analysis and 2-stage least-squares regression demonstrated that these findings were robust to bias from unmeasured confounding. Conclusions and Relevance: In this study, laparoscopic and open repair with local anesthesia were reasonable options for patients with initial unilateral inguinal hernias, and the decision should be made considering both patient and surgeon factors.

An Implementation Assessment of the Virtual Acute Care for Elders Program From the Perspective of Key Stakeholders.

OBJECTIVE: The aim of this study was to obtain feedback from key stakeholders and end users to identify program strengths and weaknesses to plan for wider dissemination and implementation of the Virtual Acute Care for Elders (Virtual ACE) program, a novel intervention that improves outcomes for older surgical patients. BACKGROUND: Virtual ACE was developed to deliver evidence-based geriatric care without requiring daily presence of a geriatrician. Previous work demonstrated that Virtual ACE increased mobility and decreased delirium rates for surgical patients. METHODS: We conducted semi-structured interviews with 30 key stakeholders (physicians, nurses, hospital leadership, nurse managers, information technology staff, and physical/occupational therapists) involved in the implementation and use of the program. RESULTS: Our stakeholders indicated that Virtual ACE was extremely empowering for bedside nurses. The program helped nurses identify older patients who were at risk for a difficult postoperative recovery. Virtual ACE also gave them skills to manage complex older patients and more effectively communicate their needs to surgeons and other providers. Nurse managers felt that Virtual ACE helped them allocate limited resources and plan their unit staffing assignments to better manage the needs of older patients. The main criticism was that the Virtual ACE Tracker that displayed patient status was difficult to interpret and could be improved by a better design interface. Stakeholders also felt that program training needed to be improved to accommodate staff turnover. CONCLUSIONS: Although respondents identified areas for improvement, our stakeholders felt that Virtual ACE empowered them and provided effective tools to improve outcomes for older surgical patients.

Racial and Ethnic Disparities in Access to Local Anesthesia for Inguinal Hernia Repair.

BACKGROUND: Many studies have identified racial disparities in healthcare, but few have described disparities in the use of anesthesia modalities. We examined racial disparities in the use of local versus general anesthesia for inguinal hernia repair. We hypothesized that African American and Hispanic patients would be less likely than Caucasians to receive local anesthesia for inguinal hernia repair. MATERIALS AND METHODS: We included 78,766 patients aged ≥ 18 years in the Veterans Affairs Surgical Quality Improvement Program database who underwent elective, unilateral, open inguinal hernia repair under general or local anesthesia from 1998-2018. We used multiple logistic regression to compare use of local versus general anesthesia and 30-day postoperative complications by race/ethnicity. RESULTS: In total, 17,892 (23%) patients received local anesthesia. Caucasian patients more frequently received local anesthesia (15,009; 24%), compared to African Americans (2353; 17%) and Hispanics (530; 19%), P < 0.05. After adjusting for covariates, we found that African Americans (OR 0.82, 95% CI 0.77-0.86) and Hispanics (OR 0.77, 95% CI 0.69-0.87) were significantly less likely to have hernia surgery under local anesthesia compared to Caucasians. Additionally, local anesthesia was associated with fewer postoperative complications for African American patients (OR 0.46, 95% CI 0.27-0.77). CONCLUSIONS: Although local anesthesia was associated with enhanced recovery for African American patients, they were less likely to have inguinal hernias repaired under local than Caucasians. Addressing this disparity requires a better understanding of how surgeons, anesthesiologists, and patient-related factors may affect the choice of anesthesia modality for hernia repair.

Wide Provider Variation in Cost for Thyroidectomy: Potential Benefits of Standardizing Practice?

OBJECTIVE(S): Identifying provider variation in surgical costs could control rising healthcare expenditure and deliver cost-effective care. While these efforts have mostly focused on complex and expensive operations, provider-level variation in costs of thyroidectomy has not been well examined. METHODS: We retrospectively evaluated 921 consecutive total thyroidectomies performed by 14 surgeons at our institution between September 2011 and July 2016. Data were extracted from the Change Healthcare Performance Analytics Program. RESULTS: Mean patient age was 47.4 ± 0.5 y, 81% were females, 64.7% were Caucasians, and 18.8% were outpatients. The number of thyroidectomies performed by the 14 surgeons ranged from 4 to 597 (mean = 66). The mean costs per provider varied widely from $4,293 to $15,529 (P < 0.001). The mean length of stay was 1d ± .03 with wide variation among providers (0-6 d). Providers whose hospital cost exceeded the institutional mean demonstrated significantly higher anesthesia fees and lab costs (P < 0.001). CONCLUSIONS: We found substantial variation in hospital cost among providers for thyroidectomy despite practicing in the same academic institution, with some surgeons spending 3x more for the same operation. Implementing institutional standards of practice could reduce variation and the costs of surgical care.

Local Anesthesia is Associated with Fewer Complications in Umbilical Hernia Repair in Frail Veterans.

BACKGROUND: The optimal anesthesia modality for umbilical hernia repair is unclear. We hypothesized that using local rather than general anesthesia would be associated with improved outcomes, especially for frail patients. METHODS: We utilized the 1998-2018 Veterans Affairs Surgical Quality Improvement Program to identify patients who underwent elective, open umbilical hernia repair under general or local anesthesia. We used the Risk Analysis Index to measure frailty. Outcomes included complications and operative time. RESULTS: There were 4958 Veterans (13%) whose hernias were repaired under local anesthesia. Compared to general anesthesia, local was associated with a 12%-24% faster operative time for all patients, and an 86% lower (OR 0.14, 95%CI 0.03-0.72) complication rate for frail patients. CONCLUSIONS: Local anesthesia may reduce the operative time for all patients and complications for frail patients having umbilical hernia repair.

Using local rather than general anesthesia for inguinal hernia repair may significantly reduce complications for frail Veterans.

BACKGROUND: Frailty predisposes patients to poor postoperative outcomes. We evaluated whether using local rather than general anesthesia for hernia repair could mitigate effects of frailty. METHODS: We used the Risk Analysis Index (RAI) to identify 8,038 frail patients in the 1998-2018 Veterans Affairs Surgical Quality Improvement Program database who underwent elective, open unilateral inguinal hernia repair under local or general anesthesia. Our outcome of interest was the incidence of postoperative complications. RESULTS: In total, 5,188 (65%) patients received general anesthesia and 2,850 (35%) received local. Local anesthesia was associated with a 48% reduction in complications (OR 0.52, 95%CI 0.38-0.72). Among the frailest patients (RAI≥70), predicted probability of a postoperative complication ranged from 22 to 33% with general anesthesia, compared to 13-21% with local. CONCLUSIONS: Local anesthesia was associated with a ∼50% reduction in postoperative complications in frail Veterans. Given the paucity of interventions for frail patients, there is an urgent need for a randomized trial comparing effects of anesthesia modality on postoperative complications in this vulnerable population.

Using local rather than general anesthesia for inguinal hernia repair is associated with shorter operative time and enhanced postoperative recovery.

BACKGROUND: Inguinal hernia repair is the most common general surgery procedure and can be performed under local or general anesthesia. We hypothesized that using local rather than general anesthesia would improve outcomes, especially for older adults. METHODS: This is a retrospective review of 97,437 patients in the Veterans Affairs Surgical Quality Improvement Program who had open inguinal hernia surgery under local or general anesthesia. Outcomes included 30-day postoperative complications, operative time, and recovery time. RESULTS: Our cohort included 22,333 (23%) Veterans who received local and 75,104 (77%) who received general anesthesia. Mean age was 62 years. Local anesthesia was associated with a 37% decrease in the odds of postoperative complications (95% CI 0.54-0.73), a 13% decrease in operative time (95% CI 17.5-7.5), and a 27% shorter recovery room stay (95% CI 27.5-25.5), regardless of age. CONCLUSIONS: Using local rather than general anesthesia is associated with a profound decrease in complications (equivalent to "de-aging" patients by 30 years) and could significantly reduce costs for this common procedure.

Using Local Anesthesia for Inguinal Hernia Repair Reduces Complications in Older Patients.

BACKGROUND: Inguinal hernia repair is the most common general surgery operation in the United States. Nearly 80% of inguinal hernia operations are performed under general anesthesia versus 15%-20% using local anesthesia, despite the absence of evidence for the superiority of the former. Although patients aged 65 y and older are expected to benefit from avoiding general anesthesia, this presumed benefit has not been adequately studied. We hypothesized that the benefits of local over general anesthesia for inguinal hernia repair would increase with age. MATERIALS AND METHODS: We analyzed 87,794 patients in the American College of Surgeons National Surgical Quality Improvement Project who had elective inguinal hernia repair under local or general anesthesia from 2014 to 2018, and we used propensity scores to adjust for known confounding. We compared postoperative complications, 30-day readmissions, and operative time for patients aged <55 y, 55-64 y, 65-74 y, and ≥75 y. RESULTS: Using local rather than general anesthesia was associated with a 0.6% reduction in postoperative complications in patients aged 75+ y (95% CI -0.11 to -1.13) but not in younger patients. Local anesthesia was associated with faster operative time (2.5 min - 4.7 min) in patients <75 y but not in patients aged 75+ y. Readmissions did not differ by anesthesia modality in any age group. Projected national cost savings for greater use of local anesthesia ranged from $9 million to $45 million annually. CONCLUSIONS: Surgeons should strongly consider using local anesthesia for inguinal hernia repair in older patients and in younger patients because it is associated with significantly reduced complications and substantial cost savings.

Race and Gender Disparities in Access to Parathyroidectomy: A Need to Change Processes for Diagnosis and Referral to Surgeons.

BACKGROUND: Hyperparathyroidism substantially impairs quality of life, and effective treatment depends on timely referral to surgeons. We hypothesized that there would be race and gender disparities in the time from initial diagnosis of hyperparathyroidism to treatment with parathyroidectomy. METHODS: We reviewed administrative data on 2289 patients with hypercalcemia (calcium > 10.5 mg/dL) and abnormal parathyroid hormone levels who were seen at a tertiary referral center from 2011 to 2016. We used two-phase parametric hazard modeling to identify predictors of time from index abnormal calcium until parathyroidectomy. RESULTS: The median age of our cohort was 63 years, and 1685 (74%) were women. Of the total patients, 1301 (57%) were Caucasian, and 946 (41%) were African-American. Only 490 (21%) patients underwent parathyroidectomy. Among patients undergoing surgery, time from index high calcium to surgical treatment was longest for African-American men, who waited a median of 13.6 months (interquartile range IQR 2-28), compared with 2.9 months (IQR 1-8) for Caucasian males (p < 0.05). African-American women waited a median of 6.7 months (IQR 2-16) versus 3.5 months (IQR 2-14) for Caucasian women (p < 0.05). At 1 year after the index abnormal calcium, only 6% of black men underwent surgery compared with 20% of white males (p < 0.05). Similarly, 13% of black women underwent surgery versus 20% of white women (p < 0.05). These differences remained significant after adjusting for age, calcium levels, insurance, and comorbidities. CONCLUSIONS: African-Americans face substantial delays in access to parathyroidectomy after diagnosis with hyperparathyroidism that could impair quality of life and increase health care costs. We must improve systems of diagnosis and referral to ensure timely treatment of hyperparathyroidism.

A Surgeon's Guide to Treating Older Patients with Colorectal Cancer.

PURPOSE OF REVIEW: Review strategies to improve outcomes of colorectal cancer treatment in older patients. RECENT FINDINGS: Older colorectal patients face many barriers to recovery during their initial inpatient stay following surgery and after leaving the hospital. In addition to the risk of inpatient morbidity and mortality, older patients are more likely to require post-acute care services, to face nutritional deficits, and to experience complications of chemoradiation. SUMMARY: In order to improve outcomes for older patients with colorectal cancer, it is important for surgeons to recognize their unique needs and to develop plans to address them. The involvement of a multidisciplinary team with geriatric experience can guide planning for surgery, the immediate postoperative recovery, and long-term survivorship.

Gender and Racial Disparities in Survival After Surgery Among Papillary and Patients With Follicular Thyroid Cancer: A 45-Year Experience.

BACKGROUND: Demographic disparities have been described for survival after thyroid cancer surgery using national registries and databases. At the institution level, we hypothesized that assessing survival after thyroid cancer surgery in a long-term cohort with diverse gender and racial groups would reveal disparities in survival. METHODS: We examined medical records of patients with papillary or follicular thyroid cancer undergoing thyroidectomy, lobectomy, and other surgical procedures from 1971 to 2016 at a tertiary referral center. We obtained information on demographics, cancer stage, procedure, and radioactive iodine (RAI). We measured survival using Kaplan-Meier estimates and Cox proportional hazards models. RESULTS: A total of 1440 (91%) patients with papillary cancer and 144 (9%) patients with follicular thyroid cancer underwent total thyroidectomy (1297, 82%), lobectomy (261, 16.5%), and other surgical procedures (26, 1.5%). Most patients (1131, 71%) were woman, and 909 (57%) were older than 45 years. Race/ethnicity included 805 (51%) white, 161 (10%) African Americans, and 618 (39%) other race/ethnicities. Both 10- and 20-year survival rates in nonwhite males were worse compared with nonwhite females (P < .0001). After controlling for age, cancer type, stage, surgical procedure, RAI, and year of surgery, nonwhite males had a higher mortality risk compared with nonwhite females (P = .0376, confidence interval (CI): 1.03-2.43), white males (P < .0001, CI: 1.88-6.54), and white females (P < .0001, CI: 3.31-9.90). CONCLUSIONS: Our diverse cohort demonstrates significant gender and racial disparities in survival after thyroid cancer surgery. To improve health outcomes and reduce health disparities among nonwhite males, interventions and long-term care management should target potentially modifiable causes of worse outcomes in this group.

Diagnosis and Management of Primary Hyperparathyroidism Across the Veterans Affairs Health Care System.

IMPORTANCE: Untreated primary hyperparathyroidism impairs quality of life and incurs substantial costs. Parathyroidectomy is a low-risk, high-success, definitive intervention. OBJECTIVES: To determine the appropriateness of diagnostic evaluation for primary hyperparathyroidism in patients with hypercalcemia and the use of parathyroidectomy for the treatment of primary hyperparathyroidism across the Veterans Affairs (VA) health care system. DESIGN, SETTING, AND PARTICIPANTS: A retrospective cohort study of veterans with hypercalcemia and primary hyperparathyroidism was conducted from January 1, 2000, through September 30, 2015, using the VA Corporate Data Warehouse, a national electronic health record-based repository. The study included 371 370 veterans with chronic hypercalcemia and 47 158 veterans with biochemical evidence of primary hyperparathyroidism diagnosed by hypercalcemia, elevated serum parathyroid hormone levels, and near-normal serum creatinine levels. Statistical analysis was performed from April 21, 2017, to April 10, 2019. MAIN OUTCOMES AND MEASURES: The proportion of veterans with hypercalcemia who have parathyroid hormone levels evaluated, the proportion of veterans with hyperparathyroidism who are treated surgically, and the factors associated with parathyroidectomy using generalized linear latent and mixed model regression. RESULTS: Of 371 370 patients with chronic hypercalcemia, 86 887 (23.4%) received further testing with parathyroid hormone level. Of 47 158 patients meeting diagnostic criteria for primary hyperparathyroidism (42 737 men [90.6%] and 4421 women [9.4%]; mean [SD] age, 67.3 [11.8] years), 6048 (12.8%) underwent parathyroidectomy. Of 5793 patients with primary hyperparathyroidism presenting with a serum calcium level more than 1 mg/dL above the upper limit of normal, 1501 (25.9%) underwent parathyroidectomy. There was a decreasing trend in the use of parathyroidectomy over time. Factors positively associated with parathyroidectomy were nephrolithiasis (odds ratio [OR], 2.23; 95% CI, 1.90-2.61) and non-Hispanic white race/ethnicity (OR, 1.31; 95% CI, 1.17-1.46), while age (OR, 0.95; 95% CI, 0.95-0.96), Elixhauser Comorbidity Index score (OR, 0.76; 95% CI, 0.72-0.80), decreased estimated glomerular filtration rate (OR, 0.52; 95% CI, 0.45-0.60), and diagnosis of osteoporosis (OR, 0.65; 95% CI, 0.52-0.80) were inversely related to surgery. CONCLUSIONS AND RELEVANCE: From this study's findings, parathyroid hormone level is infrequently tested in patients with hypercalcemia, suggesting underdiagnosis of primary hyperparathyroidism. Patients meeting diagnostic criteria for primary hyperparathyroidism are undertreated with recommended parathyroidectomy. Similar gaps have previously been observed in non-VA care of primary hyperparathyroidism, suggesting the need for a systematic evaluation of barriers to diagnosis and treatment that informs intervention design.

Intraoperative Decision Making in Parathyroid Surgery.

This article reviews intraoperative decision making related to several important aspects of parathyroid surgery. These include how to systematically identify a missing gland, when to perform a unilateral versus bilateral exploration for cure, approaches to secondary hyperparathyroidism, management of familial hyperparathyroidism, and the treatment of parathyroid cancer. The management of intraoperative complications, such as recurrent laryngeal nerve injury and devascularization of parathyroid glands, also is discussed.

Failure to Diagnose and Treat Hyperparathyroidism Among Patients with Hypercalcemia: Opportunities for Intervention at the Patient and Physician Level to Increase Surgical Referral.

BACKGROUND: Hyperparathyroidism is both underdiagnosed and undertreated, but the reasons for these deficiencies have not been described. The purpose of this study was to identify reasons for underdiagnosis and undertreatment of hyperparathyroidism that could be addressed by targeted interventions. MATERIALS AND METHODS: We identified 3,200 patients with hypercalcemia (serum calcium >10.5 mg/dL) who had parathyroid hormone (PTH) levels evaluated at our institution from 2011 to 2016. We randomly sampled 60 patients and divided them into three groups based on their PTH levels. Two independent reviewers examined clinical notes and diagnostic data to identify reasons for delayed diagnosis or referral for treatment. RESULTS: The mean age of the patients was 61 ± 16.5 years, 68% were women, and 55% were white. Fifty percent of patients had ≥1 elevated calcium that was missed by their primary care provider. Hypercalcemia was frequently attributed to causes other than hyperparathyroidism, including diuretics (12%), calcium supplements (12%), dehydration (5%), and renal dysfunction (3%). Even when calcium and PTH were both elevated, the diagnosis was missed or delayed in 40% of patients. For 7% of patients, a nonsurgeon stated that surgery offered no benefit; 22% of patients were offered medical treatment or observation, and 8% opted not to see a surgeon. Only 20% of patients were referred for surgical evaluation, and they waited a median of 16 months before seeing a surgeon. CONCLUSION: To address common causes for delayed diagnosis and treatment of hyperparathyroidism, we must improve systems for recognizing hypercalcemia and better educate patients and providers about the consequences of untreated disease. IMPLICATIONS FOR PRACTICE: This study identified reasons why patients experience delays in workup, diagnosis, and treatment of primary hyperparathyroidism. These data provide valuable information for developing interventions that increase rates of diagnosis and referral.

The Effect of Financial Conflict of Interest, Disclosure Status, and Relevance on Medical Research from the United States.

BACKGROUND: Financial interactions between industry and healthcare providers are reportable. Substantial discrepancies have been detected between industry and self-report of these conflicts of interest (COIs). OBJECTIVE: Our aim was to determine if authors who fail to disclose reportable COI are more likely to publish findings that are favorable to industry than authors with no COI. DESIGN: In this blinded, observational study of medical and surgical primary research articles in PubMed, 590 articles were reviewed. MAIN MEASURES: Reportable financial relationships between authors and industry were evaluated. COIs were considered to have relevance if they were associated with the product(s) mentioned by an article. Primary outcome was favorability, defined as an impression favorable to the product(s) discussed by an article and determined by 3 independent, blinded clinicians for each article. Primary analysis compared Incomplete Self-Disclosure to No COI. Two-level multivariable mixed-effects ordered logistic regression was used to assess factors associated with favorability. KEY RESULTS: A 69% discordance rate existed between industry and self-report in COI disclosure. When authors failed to disclose COI, their conclusions were more likely to favor industry partners than authors without COI (favorable ratings 73% versus 62%, RR 1.18, p = < 0.001). On univariate (any COI 74% versus no COI 62%, RR 1.11, p = < 0.001) and multivariable analyses, any COI was associated with favorability. CONCLUSIONS: All financial COIs (disclosed or undisclosed, relevant or not relevant, research or non-research) influence whether studies report findings favorable to industry sponsors.

Post-Acute Care among Older Adults with Stage I to III Colorectal Cancer.

BACKGROUND: Little information is available on the long-term use of post-acute care among older patients with colorectal cancer (CRC), relative to individuals without cancer. This study examines the use of post-acute care among older cancer survivors (>65 y) with CRC and compares it with noncancer patients up to 5 years from surgery. DESIGN: Retrospective cohort. SETTING: SEER-Medicare. PARTICIPANTS: Patients treated for stage I to III CRC between January 1, 2000, and December 31, 2011 (n = 40 812) and noncancer Medicare beneficiaries hospitalized for noncancer treatment matching on age, sex, race, comorbidity, and Medicaid dual eligibility. MEASUREMENTS: Incident post-acute care claims (skilled nursing, long-term care facility, and home health) from 0 to 100 days, 101 to 365 days, and 1 to 5 years from hospitalization. RESULTS: The median age was 77 years. All patients had surgery, 34% received chemotherapy, and 27% received surgery and adjuvant therapy. The cumulative incidence of any post-acute care within 100 days of hospitalization was 45.7% for stage III, 37.9% for stage I/II, and 39% for controls (p < .001). Within the CRC cohort only, the cumulative incidence of post-acute care was 2.9% (stage I/II) and 4.2% (stage III, p < .001) from 101 to 365 days and 15.8% (stage I/II) and 16.9% (stage III, p < .001) from 1 to 5 years. Increasing age, ostomies, and neoadjuvant or adjuvant therapy were associated with increased hazard of all post-acute patients within 100 days from hospitalization. From 1 to 5 years from diagnosis, adjuvant therapy was associated with greater exclusive home health care use. CONCLUSIONS: Survivorship planning among older CRC patients should include discussions of post-acute care following cancer therapy, even several years after treatment.

Why Is Hyperparathyroidism Underdiagnosed and Undertreated in Older Adults?

INTRODUCTION: Hyperparathyroidism significantly decreases quality of life, yet elderly patients are underdiagnosed and undertreated even though parathyroidectomy offers definitive cure with minimal morbidity. The purpose of this study is to determine why older patients with hyperparathyroidism are not appropriately diagnosed and referred for parathyroidectomy. METHODS: We reviewed charts for a random sample of 25 patients aged 75 and older who had hyperparathyroidism and were referred for surgical evaluation, and 25 who were not referred. Two reviewers independently evaluated medical records to identify reasons for delayed diagnosis of hyperparathyroidism and reasons for nonreferral for parathyroidectomy. RESULTS: The median age of our cohort was 84 (80-96) years, 90% were women, 60% were white, and median follow-up was 5.5 (1-17) years. In 58% of all patients, an elevated serum calcium was not acknowledged. Even when calcium and parathyroid hormone levels were both elevated, the diagnosis was missed in 28% of patients, and 16% with clear symptoms of hyperparathyroidism remained undiagnosed. For 42% of patients, a nonsurgeon informed them that surgery offered no benefit. Surgery was also rejected as a treatment for 36% of patients despite the development of new symptoms or rising calcium. CONCLUSIONS: Substantial gaps exist in processes for diagnosis and referral of patients with hyperparathyroidism that lead to underdiagnosis and undertreatment. To improve rates of diagnosis and treatment, strategies are needed to educate nonsurgeons and patients about the benefits of surgery and to modify care processes to more efficiently diagnose and refer patients.
