Emergency department utilization for pediatric gastrostomy tubes across the United States.
This study investigated the number and nature of emergency department (ED) visits to community hospitals for pediatric gastrostomy tube complication. The authors used the 2019 Nationwide Emergency Department Sample to perform a retrospective cross-sectional analysis of pediatric patients (<18 y) with a primary diagnosis of gastrostomy tube complication. Their primary outcome was a potentially preventable ED visit, defined as an encounter that did not result in any imaging, procedures, or an inpatient admission. They observed 32,036 ED visits at 535 hospitals and 15,165 (47.3%) were potentially preventable. Median age was 2 years, and 17,707 (55%) were male. Compared to White patients, patients with higher odds of potentially preventable visits were Black and Hispanic. Patients with residential zip codes in the first, second, and third median household income quartiles had higher odds of potentially preventable visits compared to the highest.

Long-term health care utilization after cardiac surgery in children covered under Medicaid.
The purpose of this study was to examine the long-term burden of health care expenditures and utilization after pediatric cardiac surgery to improve care and reduce outcome inequities. The study compared children under the age of 18 undergoing cardiac surgery from 2006-2019 to a similar cohort of children without cardiac surgical disease. The research concluded that children after cardiac surgery have substantial long-term health care needs than noncardiac surgical comparators.

Postacute care utilization and episode of care payments following common elective operations.
The purpose of the cross-sectional study was to analyze post-acute care (PAC) usage and its associated costs for patients undergoing common elective procedures. The researchers examined adult patients in a statewide administrative claims database who underwent elective cholecystectomy, ventral or incisional hernia repair (VIHR), and groin hernia repair between 2012 and 2019. The study found that among the 34,717 patients who underwent elective cholecystectomy, PAC was utilized by 0.7%, resulting in significantly higher payments ($19,047 vs $7,830, P < 0.001). For the 29,826 patients who underwent VIHR, 1.7% utilized PAC, leading to significantly higher payments ($19,766 vs $9,439, P < 0.001). Of the 37,006 patients who underwent groin hernia repair, 0.3% utilized PAC services, incurring significantly higher payments ($14,886 vs $8,062, P < 0.001). The study identified both modifiable and non-modifiable risk factors associated with PAC utilization. Morbid obesity was linked to PAC usage following VIHR. Male gender was associated with reduced odds of PAC utilization for VIHR and groin hernia repair. The researchers concluded that the study identified both modifiable (e.g., obesity) and nonmodifiable (e.g., female gender) patient factors associated with PAC utilization. To optimize patients and minimize PAC usage, it is essential to understand patient risk factors and implement systems and processes that address these factors.

Geographic proximity of family members and healthcare utilization after complex surgical procedures.
This retrospective cohort study sought to determine the relationship between a patient's proximal familial social support, defined as the geographic proximity of family members, and healthcare utilization after complex cardiovascular and oncologic procedures. The authors defined healthcare utilization outcomes as 30-day all-cause readmission unplanned readmission, nonindex hospital readmission, index hospital length of stay, and home discharge disposition. The number of first-degree relatives (FDRs) living within 30 miles of the patient was measured using 60,895 patients undergoing complex cardiovascular procedures or oncologic procedures. Compared with patients with 0 to 1 FDRs, patients with 6+ FDRs living in close proximity had significantly lower rates of all-cause readmission (12.1% vs 13.5%), unplanned readmission, nonindex readmission; higher rates of home discharge. A larger number of FDRs living within 30 miles of the patient was significantly associated with a lower likelihood of all-cause readmission, 30-day unplanned readmission, nonindex readmission; higher likelihood of home discharge; and shorter index length of stay.

The role of commercial health insurance characteristics in bariatric surgery utilization.
The goal of this study was to understand relationships among insurance plan type, out-of-pocket cost sharing, and the utilization of bariatric surgery among commercially insured patients. Over 73,000 commercially insured members of the IBM MarketScan commercial claims database who underwent bariatric surgery from 2014-17 were retroactively reviewed. Findings showed that insurance plan types with higher cost sharing have lower utilization of bariatric surgery.

Trends in contralateral prophylactic mastectomy utilization for small unilateral breast cancer.
This study describes trends in contralateral prophylactic mastectomy (CPM) utilization for small unilateral breast cancer instead of breast-conserving surgery (BCS) which is recommended. The authors used the National Cancer Database to identify women with unilateral, T1 breast cancer. Of the total cohort of 765,487, 69% underwent BCS and 31% chose mastectomy. Of 176,673 women aged 70 years or older, 75% underwent BCS and 25% chose mastectomy. CPM rates have increased in both cohorts since 2006. Patient factors such as younger age, white rate, private insurance, tumor factors, and facility factors were associated with increased CPM rates compared with unilateral mastectomy.

Increased utilization of total joint arthroplasty after Medicaid expansion.
This study examined prior analyses that greater utilization of total hip arthroplasty (THA) and total knee arthroplasty (TKA) was to be expected after Medicaid expansion in 2014. Using 2012-2015 data from the HCUP Database, 9 expansion states (Arkansas, Arizona, Colorado, Iowa, Massachusetts, Maryland, Nevada, New York, and Vermont) were compared to 2 states that did not expand Medicaid (Florida and Missouri). After adjusting for community characteristics, THA and TKA increased 15% in 2014 and 23% in 2015 within expansion states compared to 2013. In non-expansion states, compared to 2013, there were significant decreases of 18% in 2014 and 11% in 2015.

Barriers to pretransplant immunization: a qualitative interview study of pediatric solid organ transplant stakeholders.
Investigators described the experiences and beliefs of pediatric transplant stakeholders regarding factors that contribute to low pre-transplant immunization rates. Five central themes emerged: gaps in knowledge about timing and safety of pre-transplant immunizations; lack of communication, coordination, and follow-up between team members; lack of centralized immunization records; subspecialty clinics functioning as the medical home for transplant candidates, but not able to provide all needed immunizations; and differences between organ type in prioritization and completion of pre-transplant immunization. The authors recommended new tools to overcome these barriers and to increase immunization rates in transplant candidates.

Analysis of the operative utilization of concurrent rhinoplasty and endoscopic sinus surgery.
Investigators sought to quantify and analyze the concurrent performance of rhinoplasty (RP) and functional endoscopic sinus surgery (FESS) using cases from the State Ambulatory Surgery Databases of California, Florida, Maryland, and New York. They found that RP with FESS more frequently involved fewer sinuses and was also less likely to involve revision rhinoplasty. Procedures combining the two had a reduction in operating room time compared to the hypothetical sum of two standalone procedures.

Trends in emergency department utilization following common operations in New York State, 2005-2014.
Researchers examined emergency department (ED) utilization following three common surgeries: cholecystectomy, appendectomy, and inguinal hernia repair. A longitudinal analysis was conducted using data from the SPARCS New York (NY) administrative database on 746,633 who underwent those procedures from 2005 to 2014. Nearly 1 in 10 patients who underwent cholecystectomy or appendectomy and 1 in 20 patients went to the ED after discharge. Of those, only 9.5% cholecystectomy, 9.1% appendectomy, and 5.1% inguinal hernia repair patients were readmitted indicating possible overutilization of the ED following common operations.

Prescription patterns and opioid usage in sinonasal surgery.
The goal of this study was to identify factors associated with variable opioid usage and to delineate optimal prescription patterns for sinonasal surgery. The researchers found that patients used 9.3% of their full prescription and only 2.6% required a refill. The amount used was not associated with complexity of endoscopic sinus surgery, type of opiate prescribed, gender, distance living from hospital, or current opioid usage before surgery. They concluded that opioids are overprescribed after sinonasal surgery and that the amount of postoperative opiate prescribed should be greatly reduced and may be based on the specific procedures performed.

Utilization of minimally invasive surgery and its association with chemotherapy for locally advanced gastric cancer.
This study compared outcomes of patients with T3 or greater and/or N+ gastric carcinoma who had minimally invasive surgery (MIS) or traditional open surgery. Patients who received MIS had a greater likelihood of receiving postoperative chemotherapy. Patients from the National Cancer Database (21,872) from 2010 to 2015 were identified. The majority (72.2%) received open surgery although MIS rates went up during that time period. Predictors of MIS were Asian race, any insurance coverage and treatment at high-volume centers. Survival rates were higher for MIS patients although that could be explained by their increased likelihood of receiving adjuvant chemotherapy.

Impact of statewide essential health benefits on utilization of bariatric surgery.
This study looked at the utilization of bariatric surgery after it was included in the Affordable Care Act’s essential health benefits program. The program required individual and small-group insurance plans in 23 states to cover the surgery. Investigators used IBM MarketScan commercial claims data from 2009 to 2016. While bariatric surgery utilization increased in all states after ACA implementation, it was no greater in states with a bariatric surgery essential health benefit. Reasons why can be explored in further studies.

Increased healthcare utilization for medical comorbidities prior to surgery improves postoperative outcomes.
The objective of this study was to evaluate the impact of optimization of preoperative comorbidities by nonsurgical clinicians on short-term postoperative outcomes. Findings demonstrated an association between the use of nonsurgical clinician visits by comorbid patients prior to surgery and a significantly lower rate of complications. Recommendations included the prospective study of preoperative optimization as a potential mechanism for improving postoperative outcomes.

Underimmunization of the solid organ transplant population: An urgent problem with potential digital health solutions.
This paper describes ways that digital health technologies may help solid organ transplant recipients stay free from vaccine-preventable infections so they are not underimmunized at the time of transplant and thereafter. Due to vaccine hesitancy and refusal in the general population, recipients can no longer rely on herd immunity to protect them. Digital health technologies can provide accurate information about vaccine safety, efficacy and timing in the pre- and post-transplant periods; make complete immunization records universally available and easily accessible; enable communication between patients and multiple providers; and provide automated vaccine reminders to both patients and providers.

Utilization and treatment patterns of cytoreduction surgery and intraperitoneal chemotherapy in the United States.
This paper discusses utilization and treatment patterns of cytoreduction surgery and intraperitoneal chemotherapy (CRS/IPC) treatment for patients with peritoneal metastases (PM) in the United States. This treatment is becoming more popular in the US. The authors used the National Inpatient Sample to identify patients from 2006 to 2015 who underwent CRS/IPC. The number of CRS/IPC treatments increased from 189 to 1540. The most common indication was for appendiceal cancer, followed by ovarian and colorectal cancers. The procedure was performed the most in large teaching hospitals. The authors recommend the creation of a national registry dedicated to cases of IPC to help evaluate further use and outcomes.

Rates of sialoendoscopy and sialoadenectomy in 5,111 adults with private insurance.
The purpose of this study was to determine frequencies and trends in sialoendoscopy and sialoadenectomy for the treatment of obstructive, non-neoplastic submandibular salivary gland disease. Researchers conducted an epidemiologic study of insurance claims from 2006 to 2013 in a large, private insurance claims database; 5,111 adults with sialadenitis who had a sialoendoscopy or submandibular gland excision were included. The results of this study indicate that the use of sialoendoscopy procedures has increased over time, while the overall rate of sialoadenectomy has decreased, but the authors conclude that both procedures are safe for the treatment of patients with sialadenitis and sialolithiasis.

Mechanisms of age and race differences in receiving minimally invasive inguinal hernia repair.
Black patients and older adults are less likely to receive minimally invasive hernia repair. In this study, the investigators explored the association between race, age, and surgeon utilization of minimally invasive surgery (MIS) with the likelihood of receiving MIS inguinal hernia repair. The investigators concluded that race differences were explained by surgeon MIS utilization, implicating access to MIS-performing surgeon as a mediator. Conversely, age disparity was independent of MIS utilization, even after adjusting for comorbidities, indicating some degree of provider bias against performing MIS repair in older patients.

The purpose of this retrospective cohort study was to assess whether trends in elective and urgent/emergent colectomy changed after July 2006. The authors suggest that given the risks associated with elective colectomy, their findings demonstrate the need for a more evidence-based decision-making process, incorporating both patient preferences and patient-reported outcomes, for those considering elective colectomy for uncomplicated and some cases of complicated diverticulitis.

Utilization trends, outcomes, and cost in minimally invasive lobectomy.
The objective of this study was to compare outcomes and hospitalization costs among patients undergoing open, video-assisted thoracoscopic surgery (VATS) and RATS lobectomy. The investigators concluded that minimally invasive approaches were associated to improved clinical outcomes compared with open lobectomy. However, only robotic-assisted lobectomy has had rapid growth in utilization. Despite additional cost, RATS lobectomy appeared to provide a viable minimally invasive alternative for general thoracic procedures.

Investigation of bias in an epilepsy machine learning algorithm trained on physician notes.
Racial disparities in the utilization of epilepsy surgery are well documented, but it is unknown whether a natural language processing (NLP) algorithm trained on physician notes would produce biased recommendations for epilepsy presurgical evaluations. To assess this, an NLP algorithm was trained to identify potential surgical candidates using 1097 notes from 175 epilepsy patients with a history of resective epilepsy surgery and 268 patients who achieved seizure freedom without surgery (total N = 443 patients).

Prevalence and cost of care cascades after low-value preoperative electrocardiogram for cataract surgery in fee-for-service Medicare beneficiaries.
This study examined the use and outcomes of preoperative electrocardiogram (EKG) for cataract surgery recipients on Medicare. The outcomes measured were cascade events if the EKG results were problematic. The study compared 110,183 cataract surgery recipients with 97,775 non-surgery participants (63.1% female). For the recipient group, 12,408 (11.3%) received a preoperative EKG (65.6% of them were female). Of those, 1978 (15.9%) had at least 1 potential cascade event. Additional tests, treatments, and cardiology visits added an additional estimated $35 million in addition to the $3.2 million spent on preoperative EKGs. Preoperative EKG recipients who were older, had more chronic conditions, lived in more cardiologist-dense areas, or had their EKG performed by a cardiac specialist rather than a primary care physician were more likely to experience a cascade event.

Characterising potential bone scan overuse amongst men treated with radical prostatectomy.
The authors characterized bone scan use after radical prostatectomy (RP) using data from a large, national integrated delivery system. They found a substantial rate of bone scan utilization after RP. The majority were performed for prostate-specific antigen levels in which the likelihood of a positive test was low. They recommended more judicious use of imaging in the post-RP setting.

Two-state comparison of total joint arthroplasty utilization following Medicaid expansion.
The aim of this study was to determine whether Medicaid expansion was associated with increased utilization rates of total hip arthroplasty (THA) and total knee arthroplasty (TKA) in Illinois (which expanded Medicaid) relative to Missouri (which did not expand Medicaid). The investigators concluded that their study demonstrated that Medicaid expansion in Illinois was associated with increased utilization of THA and TKA. They suggested that further study is needed to understand the impact of Medicaid expansion in other states and for other procedures.
