ABSTRACT

IMPORTANCE: Differences in the rate of diagnosis of POP have been described based on race and ethnicity; however, there are few data available on the management and treatment patterns of POP based on multiple factors of socioeconomic status and deprivation. OBJECTIVE: The objective of this study was to investigate the association between pelvic organ prolapse (POP) management and the Neighborhood Deprivation Index (NDI), a standardized multidimensional measure of socioeconomic status. METHODS: This retrospective cohort study included female members of a large integrated health care delivery system who were 18 years or older and had ≥4 years of continuous health care membership from January 1, 2015, to December 31, 2019. Demographic, POP diagnosis, urogynecology consultation, and surgical treatment of POP were obtained from the electronic medical record. Neighborhood Deprivation Index data were extrapolated via zip code and were reported in quartiles, with higher quartiles reflecting greater deprivation. Descriptive, bivariate, and logistic regression analyses were conducted by NDI. RESULTS: Of 1,087,567 patients identified, 34,890 (3.2%) had a POP diagnosis. Q1, the least deprived group, had the highest prevalence of POP (26.3%). Most patients with POP identified as White (57.3%) and represented approximately a third of Q1. Black patients had the lowest rate of POP (5.8%) and comprised almost half of Q4, the most deprived quartile. A total of 13,730 patients (39.4%) had a urogynecology consultation, with rates ranging from 23.6% to 26.4% (P < 0.01). Less than half (12.8%) of patients with POP underwent surgical treatment, and the relative frequencies of procedure types were similar across NDI quartiles except for obliterative procedures (P = 0.01). When controlling for age, no clinically significant difference was demonstrated. CONCLUSIONS: Differences in urogynecology consultation, surgical treatment, and surgical procedure type performed for prolapse across NDI quartiles were not found to be clinically significant. Our findings suggest that equitable evaluation and treatment of prolapse can occur through a membership-based integrated health care system.

ABSTRACT

Introduction Intraoperative radiation therapy (IORT) may not be as effective in the community compared with clinical trials. Methods The authors reviewed data from the electronic health records of patients who received IORT between February 2014 and February 2020 at a single center within a large integrated health care system. The primary outcome was ipsilateral breast tumor recurrence. Results Of 5731 potentially eligible patients, 245 (4.3%) underwent IORT (mean age: 65.4 ± 0.4 years; median follow-up time: 3.5 years ± 2.2 months). According to the American Society for Radiation Oncology's accelerated partial breast irradiation guidelines based on final pathology, 51% of patients were suitable candidates for IORT, 38.4% were cautionary, and 10.6% were unsuitable. For adjuvant therapy, 6.5% had consolidative whole breast irradiation, and 66.4% received endocrine treatment. At the median follow-up time of 3.5 years, overall ipsilateral breast tumor recurrence was 3.7%. Recurrences tended to be more frequent in patients who refused or did not complete endocrine treatment than in those who received it (7.4% vs 1.9%, p = 0.07). The complication rate was 14.7%, with seroma being the most common (8.2%). Discussion The IORT ipsilateral breast tumor recurrence rate of 3.7% confirms a higher-than-expected rate compared to randomized clinical trials, possibly due to less compliance with endocrine therapy. Conclusion The authors subsequently revised their IORT protocol to require endocrine treatment as a part of the IORT treatment plan and to strongly recommend adjuvant whole breast irradiation for all patients deemed cautionary or unsuitable for IORT according to the American Society for Radiation Oncology's accelerated partial breast irradiation guidelines.

ABSTRACT

Introduction The COVID-19 pandemic drove rapid, widespread adoption of telehealth (TH). We evaluated surgical telehealth utilization and outcomes for newly diagnosed breast cancer patients during the initial pandemic period. Methods We identified patients with breast cancer diagnosed March 17, 2020 through May 17, 2020 who underwent surgery as the initial treatment. Clinicodemographic characteristics were collected. Initial consultation types (office, telephone, or video) were categorized. Outcomes included time to consultation, surgeon touchpoints, time to surgery, surgery types, and reexcision rates. Continuous variables were compared using Mann-Whitney tests or t-tests, and categorical variables were compared using χ2 or Fisher's exact tests. Results Of 158 patients, 56% had initial telehealth consultations (21% telephone, 35% video) and 42% did not have a preoperative physical examination. Age, race/ethnicity, and stage distributions were similar between initial visit types. Median time to consultation was lower in the initial telehealth group than the office group (6 days vs 9 days, p = 0.01). Other outcomes (surgeon touchpoints, time to surgery, surgery type, reconstruction) were similar between visit types. We observed higher reexcision rates in patients with initial telehealth visits (20% telehealth vs 4% office, p = 0.01), but evaluation was limited by small numbers. The reexcision rate was 13% for patients with telehealth visits and no preoperative physical exam. Discussion During the initial pandemic period, the majority of new breast cancer patients had an initial telehealth surgical consultation. Office and telehealth consultation visits had comparable numbers of postconsultation surgeon touchpoints and most outcomes. Our findings suggest that telehealth consultations may be feasible for preoperative breast cancer consultations.

ABSTRACT

BACKGROUND: Reexcision after breast-conserving surgery (BCS) is costly for patients, but few studies have captured the economic burden to a healthcare system. We quantified operating room (OR) charges as well as OR time and then modeled expected savings of a reexcision reduction initiative. METHODS: We performed a retrospective cohort review of all breast cancer patients with BCS between January 1, 2016 and December 31, 2020. Operating room charges of disposable supplies and implants as well as operative time were calculated. RESULTS: During the 5-year period, the 8804 patients who underwent BCS, 1628 (18.5%) required reexcision. The reexcision cohort was younger (61 vs. 64 years, p < 0.001), more likely to have ductal carcinoma in situ (DCIS) (23.7% vs. 15.2%, p < 0.001), and had larger tumors (T1+T2 73.2% vs. 83.1%, p < 0.001). Reexcision costs represented 39% of total costs, the cost per patient for surgery was fourfold higher for reexcision patients. Reexcision operations comprised 14% of total operating room (OR) time (1848 of 13,030 hours). The reexcision rate for 54 surgeons varied from 7.2-39.0% with 46% (n = 25) having a reexcision rate >20%. A model simulating reducing reexcision rates to 20% or below for all surgeons reduced the reexcision rate to 16.2% overall. Using per procedure data, the model predicted a decrease in reexcision operations by 18% (327 operations), OR costs by 14% ($287,534), and OR time by 11% (204 hours). CONCLUSIONS: Reexcision after BCS represents 39% of direct OR costs and 14% of OR time in our healthcare system. Modest improvements in surgeon reexcision rates may lead to significant economic and OR time savings.

ABSTRACT

PURPOSES: To delineate operational changes in Kaiser Permanente Northern California breast care and evaluate the impact of these changes during the initial COVID-19 Shelter-in-Place period (SiP, 3/17/20-5/17/20). METHODS: By extracting data from institutional databases and reviewing electronic medical charts, we compared clinical and treatment characteristics of breast cancer patients diagnosed 3/17/20-5/17/20 to those diagnosed 3/17/19-5/17/2019. Outcomes included time from biopsy to consultation and treatment. Comparisons were made using Chi-square or Wilcoxon rank-sum tests. RESULTS: Fewer new breast cancers were diagnosed in 2020 during the SiP period than during a similar period in 2019 (n = 247 vs n = 703). A higher percentage presented with symptomatic disease in 2020 than 2019 (78% vs 37%, p < 0.001). Higher percentages of 2020 patients presented with grade 3 (37% vs 25%, p = 0.004) and triple-negative tumors (16% vs 10%, p = 0.04). A smaller percentage underwent surgery first in 2020 (71% vs 83%, p < 0.001) and a larger percentage had neoadjuvant chemotherapy (16% vs 11%, p < 0.001). Telehealth utilization increased from 0.8% in 2019 to 70.0% in 2020. Times to surgery and neoadjuvant chemotherapy were shorter in 2020 than 2019 (19 vs 26 days, p < 0.001, and 23 vs 28 days, p = 0.03, respectively). CONCLUSIONS: During SiP, fewer breast cancers were diagnosed than during a similar period in 2019, and a higher proportion presented with symptomatic disease. Early-stage breast cancer diagnoses decreased, while metastatic cancer diagnoses remained similar. Telehealth increased significantly, and times to treatment were shorter in 2020 than 2019. Our system continued to provide timely breast cancer treatment despite significant pandemic-driven disruption.

ABSTRACT

BACKGROUND: Intraoperative ultrasound (IUS) localization for breast cancer is a noninvasive localization technique. In 2015, an IUS program for breast-conserving surgery (BCS) was initiated in a large, integrated health care system. This study evaluated the clinical results of IUS implementation. METHODS: The study identified breast cancer patients with BCS from 1 January to 31 October 2015 and from 1 January to 31 October 2019. Clinicopathologic characteristics were collected, and localization types were categorized. Clinical outcomes were analyzed, including localization use, surgeon adoption of IUS, day-of-surgery intervals, and re-excision rates. Multivariate logistic regression analysis was performed to evaluate predictors of re-excision. RESULTS: The number of BCS procedures increased 23%, from 1815 procedures in 2015 to 2226 procedures in 2019. The IUS rate increased from 4% of lumpectomies (n = 79) in 2015 to 28% of lumpectomies (n = 632) in 2019 (p < 0.001). Surgeons using IUS increased from 6% (5 of 88 surgeons) in 2015 to 70% (42 of 60 surgeons) in 2019. In 2019, 76% of IUS surgeons performed at least 25% of lumpectomies with IUS. The mean time from admission to incision was shorter with IUS or seed localization than with wire localization (202 min with IUS, 201 with seed localization, 262 with wire localization in 2019; p < 0.001). The IUS re-excision rates were lower than for other localization techniques (13.6%, vs 19.6% for seed localization and 24.7% for wire localization in 2019; p = 0.006), and IUS predicted lower re-excision rates in a multivariable model (odds ratio [OR], 0.59). CONCLUSIONS: In a high-volume integrated health system, IUS was adopted for BCS by a majority of surgeons. The use of IUS decreased the time from admission to incision compared with wire localization, and decreased re-excision rates compared with other localization techniques.

ABSTRACT

BACKGROUND: Patients 65 years old or older with early endocrine-responsive breast cancer have many treatment options, including no radiation. This study aimed to evaluate treatment preference when intraoperative radiation therapy (IORT) is offered in this population. METHODS: The study reviewed patients 65 years old or older with a diagnosis of early-stage endocrine-responsive breast cancer in 2016-2019 at a single hospital in a large integrated health care system. Electronic medical records of multidisciplinary breast tumor board discussion, treatment options documented by the treatment team, and final treatment offered were reviewed. Variables including age at biopsy, language, endocrine treatment, and comorbidities were collected. Regression analysis was used to evaluate for variables associated with patients' choice regarding radiation treatment. RESULTS: The institutional IORT guidelines were met by 63 patients in the described age group who had a documented offer of all radiation treatment options. The median age of the patients was 70 years (interquartile range 63-77 years). Overall, 74.6% of the patients chose IORT, and 14.3% opted for whole-breast irradiation. Only 4.8% chose to omit radiation after breast-conserving surgery, and 6.3% chose mastectomy. The patients who chose IORT were more likely to receive endocrine treatment (odds ratio 3.70; p = 0.03). Age, race, language, and comorbidities were not associated with preference for IORT (p < 0.05). CONCLUSIONS: Patients 65 years old or older with early-stage endocrine-responsive breast cancer preferred to have IORT despite counsel about the lack of survival benefit. This study suggests that local cancer control with the convenient radiation delivery method is important to the described patient population.

ABSTRACT

The risk of skin cancer in connective tissue disease and the impact of immunosuppressive therapy on this risk has not been well studied. The objective of this study is to investigate the risk of non-melanoma skin cancer in patients with connective tissue disease and to assess the impact of immunosuppressive therapy on this risk. This is a retrospective case control cohort study of 8281 patients with connective tissue disease (systemic lupus erythematosus, Sjogren’s disease and scleroderma) and 8281 age, race, and gender matched controls followed for a 5-year period between 2002-2012, who obtained their care from a large integrated multispecialty group practice in Northern California. The odds ratio for developing squamous cell skin cancer among patients with connective tissue disease was 1.47 (95% CI, 1.14-1.90) (P=0.003) while the odds ratio for developing all non-melanoma skin cancer was 1.26 (95% CI, 1.08-1.49) (P=0.005). Patients on immunosuppressive medication for at least one year had an OR of 1.69 (95% CI, 1.16-2.45) of developing non-melanoma skin cancer (P=0.006) when controlled for age, race, gender, type of connective tissue disease, smoking status, and health care utilization. Our study shows an increased risk of non-melanoma skin cancer among patients with connective tissue disease. We also note that patients on immunosuppressive therapy for at least one year had an increased incidence of non-melanoma skin cancer. Further studies are needed to confirm these findings.

ABSTRACT

PURPOSE: To determine the association between the use of preoperative antibiotics and the risk of postoperative infection after simple knee arthroscopy. METHODS: The electronic medical records of a large integrated health care organization were used to identify patients who underwent simple knee arthroscopy between 2007 and 2012. Patient demographics, potential infection risk factors, and antibiotic administration data were extracted. Simple knee arthroscopy included debridement, meniscectomy, meniscus repair, synovectomy, microfracture, and lateral release. Complex knee arthroscopy, septic knees, and cases involving fractures were excluded. Deep infection was defined as a positive synovial fluid culture or signs and symptoms of infection and gross pus in the knee. Superficial infection was defined as clinical signs of infection localized to a portal site and treatment with an antibiotic. RESULTS: Of 40,810 simple knee arthroscopies, 32,836 (80.5%) received preoperative antibiotics and 7,974 (19.5%) did not. There were 25 deep infections in the antibiotic group (0.08%) and 11 in the no-antibiotics group (0.14%) (risk ratio = 0.55, 95% confidence interval: 0.27 to 1.12, P = .10). There were 134 superficial infections in the antibiotic group (0.41%) and 32 in the no-antibiotics group (0.40%) (risk ratio = 1.01, 95% confidence interval: 0.29 to 1.49, P = .93). CONCLUSIONS: In our large sample of patients who underwent simple knee arthroscopy, there was no association between preoperative antibiotic use and postoperative deep or superficial infection rates at the 95% confidence level (P = .05). There was an association between preoperative antibiotic use and a decreased deep infection rate at the P = .10 level. LEVEL OF EVIDENCE: Level IV, case series.

ABSTRACT

Biopsies of liver masses that prove to be hepatocellular carcinomas (HCCs) are associated with a risk of seeding the abdominal or chest wall with tumor cells. The reported frequency of seeding varies greatly in the literature. We performed a retrospective cohort study in a large integrated health care system to examine rates of seeding in patients with HCC who had targeted liver biopsies, ablations, or both performed by community radiologists. We reviewed pathology and radiology records to determine the occurrence of wall seeding, defined as a chest or abdominal wall lesion along a definite or probable needle tract. A total of 1,015 patients had targeted liver biopsies (795), ablations (72), or both (148). Multiple procedures were done in 284 patients (28%). Six cases of seeding were identified. The rate of wall seeding was 2/795 patients (0.13%; 95% confidence interval [CI], 0.00%-0.60%) if only biopsies were done versus 4/220 (1.82%; 95% CI, 0.05%-3.58%) if ablations were performed (P = 0.01). The rate was 0/72 (0.00%; 95% CI, 0.00%-0.04%) with ablations alone and 4/148 (2.70%; 95% CI, 0.74%-6.78%) if both procedures were done (P = 0.31). Of those with 1 year follow-up (n = 441), the rate of seeding was 2/269 (0.74%; 95% CI, 0.00%-1.77%) if biopsies alone were done and 4/172 (2.33%; 95% CI, 0.07%-4.58%) if ablations were done. In none of the cases was the seeding a proximate cause of death. Conclusion: Biopsies of liver masses are associated with a low rate of wall seeding when performed in a community setting and when they are the sole procedures. Ablations may have a higher rate of seeding, particularly if done with biopsies, but are still rare. (Hepatology Communications 2017;1:841-851).

ABSTRACT

The traditional protocol for treatment after ankle fracture in the diabetic patient involves a period of prolonged non-weightbearing to reduce the incidence of complications. The goal of the present study was to identify the risk factors and complications associated with early protected weightbearing after closed ankle fractures in patients with diabetes. The data from 73 diabetic patients with operatively and nonoperatively treated ankle fractures were retrospectively reviewed. All patients were allowed to begin protected weightbearing in a cast or removable boot at 2 weeks after the index injury or surgery. The mean follow-up period was 51 (range of 26 to 480) weeks. Complications occurred in 25% of the operative cases and 8% of the nonoperative cases. In both categories, the complication rate was less than that from existing reports using prolonged non-weightbearing. Wound dehiscence was the most common complication in the operatively treated patients (18.8%). A statistically significant difference was found in the complications rates for the patients aged >60 years (p = .0403). No statistically significant differences were identified according to hemoglobin A1c, the presence of peripheral neuropathy, smoking status, fracture type, or the presence of end-stage renal disease. The results of the present study suggest that early protected weightbearing after closed ankle fractures in diabetic patients is fairly safe, with an acceptable complication rate. However, the patients selected for early weightbearing had low comorbidity profiles, which might have accounted, in part, for the low complication rate.

ABSTRACT

BACKGROUND: A prolonged corrected QT (QTc) interval is a marker for an increased risk of sudden cardiac death. We evaluated the relationship between oral contraceptive (OC) use, type of OC, and QTc interval. METHODS: We identified 410,782 ECGs performed at Northern California Kaiser Permanente on female patients between 15 and 53 years from January, 1995 to June, 2008. QT was corrected for heart rate using log-linear regression. OC generation (first, second and third) was classified by increasing progestin androgenic potency, while the fourth generation was classified as antiandrogenic. RESULTS: Among 410,782 women, 8.4% were on OC. In multivariate analysis after correction for comorbidities, there was an independent shortening effect of OCs overall (slope = -0.5 ms; SE = 0.12, P < 0.0002). Users of first and second generation progestins had a significantly shorter QTc than nonusers (P < 0.0001), while users of fourth generation had a significantly longer QTc than nonusers (slope = 3.6 ms, SE = 0.35, P < 0.0001). CONCLUSION: Overall, OC use has a shortening effect on the QTc. Shorter QTc is seen with first and second generation OC while fourth generation OC use has a lengthening effect on the QTc. Careful examination of adverse event rates in fourth generation OC users is needed.
