An economic analysis of pancreaticoduodenectomy: should costs drive consumer decisions?

Background

Consumer groups campaign for cost transparency believing that patients will select hospitals accordingly. We sought to determine whether the cost of pancreaticoduodenectomy (PD) should be considered in choosing a hospital.

Methods

Using the Nationwide Inpatient Sample database, we analyzed charges for patients who underwent PD from 2000 to 2010. Outcomes were stratified by hospital volume.

Results

A total of 15,599 PDs were performed in 1,186 hospitals. The median cost was $87,444 (interquartile range $16,015 to $144,869). High volume hospitals (HVH) had shorter hospital stay (11 vs 15 days, P < .001) and mortality (3% vs 7.6%, P < .001). PD performed at low volume hospitals had higher charges compared with HVH ($97,923 vs $81,581, P < .001). On multivariate analysis, HVH was associated with a lower risk of mortality, while extremes in hospital costs, cardiac comorbidity, and any complication were significant predictors of mortality.

Conclusion

Although PDs performed at HVH are associated with better outcomes and lower hospital charges, costs should not be the primary determinant when selecting a hospital.     

Challenges of Surgery in Developing Countries: A Survey of Surgical and Anesthesia Capacity in Uganda’s Public Hospitals

Background  

There are large disparities in access to surgical services due to a multitude of factors, including insufficient health human resources, infrastructure, medicines, equipment, financing, logistics, and information reporting. This study aimed to assess these important factors in Uganda’s government hospitals as part of a larger study examining surgical and anesthesia capacity in low-income countries in Africa.     

Comparison of the clinical and economic outcomes between open and minimally invasive appendectomy and colectomy: evidence from a large commercial payer database

Background  

Appendectomy and colectomy are commonly performed surgical procedures. Despite evidence demonstrating advantages with the minimally invasive surgical (MIS) approach, open procedures occur with greater prevalence. Therefore, there is still controversy as to whether the MIS approach is safer or more cost effective.     

Full‐thickness neorectal prolapse after transanal transabdominal proctosigmoidectomy for low rectal cancer: a cohort study

Aim

Transanal transabdominal proctosigmoidectomy (TATA) with a coloanal anastomosis is an alternative to abdominoperineal excision of the rectum (APR) for low rectal cancer. Neorectal prolapse is an unusual complication following TATA. This study aimed to determine the incidence of neorectal prolapse after TATA for low rectal cancer.

Method

This cohort study was conducted in a tertiary referral colorectal centre. From a prospectively maintained database including 1093 patients treated for rectal cancer between 1984 and 2016 we identified those who underwent sphincter‐preserving surgery. Data regarding the incidence, management and outcomes of neorectal prolapse were analysed.

Results

A total of 409 patients were identified, of whom 185 underwent open surgery and 224 a minimally invasive surgical procedure (MIS). All received neoadjuvant chemoradiation. Neorectal prolapse occurred in 4.6% (n = 19) with an incidence of 2.2% in the open and 6.7% in the MIS group (P = 0.023), with no difference between MIS techniques. There was one recurrence of neorectal prolapse (5.9%). The incidence of neorectal prolapse was higher in women (9.5%) than men (2.5%) (P = 0.011). There were no differences in local recurrence rates between the neorectal prolapse group (5.3%) and our population without prolapse (3.4%) (P = 0.79).

Conclusion

Neorectal prolapse is a rare occurrence following minimally invasive sphincter‐saving surgical procedures performed for rectal cancer. It appears to be more frequent in patients who undergo MIS procedures and in women.     

Socioeconomic and racial differences in treatment for breast cancer at a low-volume hospital

Purpose  

Population-based studies have revealed higher mortality among breast cancer patients treated in low-volume hospitals. Other studies have demonstrated disparities in race and socioeconomic status (SES) in breast cancer survival. The purpose of our study was to determine whether nonwhite or low-SES patients are disproportionately treated in low-volume hospitals.     

Trends in Racial Disparities in Pancreatic Cancer Surgery

Objectives

We tested three hypotheses: (1) blacks with pancreatic cancer are recommended surgical resection less often than whites; (2) when recommended surgical resection, blacks refuse surgery more often than whites; and lastly, (3) racial differences in refusal of surgical resection have decreased over time.

Methods

A retrospective cohort study was conducted on patients with potentially resectable, nonmetastatic pancreatic adenocarcinoma of the Surveillance, Epidemiology, and End Results registry from 1988 to 2009. Univariate and multivariable logistic regression analyses were performed to assess whether differences in the proportion of whites versus blacks refusing surgery among patients recommended for resection changed over time.

Results

A total of 35,944 patients were included; most were white (87.6 %). After adjusting for covariates including tumor stage, pancreatic cancer resection was less often recommended to and performed in blacks compared with whites (adjusted odds ratio (aOR) 0.88, 95 % confidence interval (CI) 0.82–0.95; aOR 0.83, 95 % CI 0.76–0.91, respectively). Blacks also underwent surgical resection less often when surgery was recommended (aOR 0.73, 95 % CI 0.64–0.85). Racial disparities in surgery recommendation and its performance did not decrease from 1988 to 2009. In multivariable adjusted analyses, blacks refused surgery more often when it was recommended (aOR in 1988 4.75, 95 % CI 2.51–9.01); this disparity decreased over time (aOR 0.93 per year, 95 % CI 0.89–0.97).

Conclusions

Although racial disparities in pancreatic cancer surgery refusal have diminished over the past two decades, significant disparities in the recommendation and performance of surgery persist. It is likely that both provider- and patient-level factors have a substantial impact on surgery recommendation and its acceptance. The identification of such factors is critical to design a framework for eliminating disparities in cancer-directed surgery for pancreatic cancer.     

Does Minimally Invasive Total Knee Arthroplasty Improve Isokinetic Torque?

Background  

Less invasive dissection of the extensor apparatus, one of the aspects of minimally invasive surgical (MIS) TKA, might result in less reduction of postoperative quadriceps strength. However, it is unclear whether MIS is associated with less strength reduction.     

Nicaraguan Surgical and Anesthesia Infrastructure: Survey of Ministry of Health Hospitals

Background

Developing countries have surgical and anesthesia needs that are unique and disparate compared to those of developed countries. However, the extent of these disparities and the specific country-based needs are, for the most part, unknown. The goal of this study was to assess the surgical capacity of Nicaragua’s public hospitals as part of a multinational study.

Methods

A survey adapted from the World Health Organization Tool for Situational Analysis to Assess Emergency and Essential Surgical care was used to study 28 primary, departmental, regional, and national referral hospitals within the Ministry of Health system. Data were obtained at the national and hospital levels via interviews with administrators and surgical and anesthesia chiefs of services.

Results

There are 580 obstetrician/gynecologists (OB/GYN), 1,040 non-OB/GYN surgeons, and 250 anesthesiologists in Nicaragua. Primary, departmental, regional, and national referral hospitals perform an annual average of 374, 4,610, 7,270, and 7,776 surgeries, respectively. All but six primary hospitals were able to perform surgeries. Four hospitals reported routine water shortages. Routine medication shortages were reported in 11 hospitals. Eight primary hospitals lacked blood banks on site. Of 28 hospitals, 22 reported visits from short-term surgical brigades within the past 2 years. Measurement of surgical outcomes was inconsistent across hospitals.

Conclusions

Surgical capacity varies by hospital type, with primary hospitals having the least surgical capacity and surgical volume. Departmental, regional, and national referral hospitals have adequate surgical capacity. Surgical subspecialty care appears to be insufficient, as evidenced by the large presence of NGOs and other surgical brigade teams filling this gap.     

Equivalent Treatment and Survival after Resection of Pancreatic Cancer at Safety-Net Hospitals

Background

Due to disparities in access to care, patients with Medicaid or no health insurance are at risk of not receiving appropriate adjuvant treatment following resection of pancreatic cancer. We have previously shown inferior short-term outcomes following surgery at safety-net hospitals. Subsequently, we hypothesized that safety-net hospitals caring for these vulnerable populations utilize less adjuvant chemoradiation, resulting in inferior long-term outcomes.

Methods

The American College of Surgeons National Cancer Data Base was queried for patients diagnosed with pancreatic adenocarcinoma (n = 32,296) from 1998 to 2010. Hospitals were grouped according to safety-net burden, defined as the proportion of patients with Medicaid or no insurance. The highest quartile, representing safety-net hospitals, was compared to lower-burden hospitals with regard to patient demographics, disease characteristics, surgical management, delivery of multimodal systemic therapy, and survival.

Results

Patients at safety-net hospitals were less often white, had lower income, and were less educated. Safety-net hospital patients were just as likely to undergo surgical resection (OR 1.03, p = 0.73), achieving similar rates of negative surgical margins when compared to patients at medium and low burden hospitals (70% vs. 73% vs. 66%). Thirty-day mortality rates were 5.6% for high burden hospitals, 5.2% for medium burden hospitals, and 4.3% for low burden hospitals. No clinically significant differences were noted in the proportion of surgical patients receiving either chemotherapy (48% vs. 52% vs. 52%) or radiation therapy (26% vs. 30% vs. 29%) or the time between diagnosis and start of systemic therapy (58 days vs. 61 days vs. 53 days). Across safety-net burden groups, no difference was noted in stage-specific median survival (all p > 0.05) or receipt of adjuvant as opposed to neoadjuvant systemic therapy (82% vs. 85% vs. 85%). Multivariate analysis adjusting for cancer stage revealed no difference in survival for safety-net hospital patients who had surgery and survived > 30 days (HR 1.02, p = 0.63).

Conclusion

For patients surviving the perioperative setting following pancreatic cancer surgery, safety-net hospitals achieve equivalent long-term survival outcomes potentially due to equivalent delivery of multimodal therapy at non-safety-net hospitals. Safety-net hospitals are a crucial resource that provides quality long-term cancer treatment for vulnerable populations.

     

Evaluating the impact of a minimally invasive pediatric surgeon on hospital practice: comparison of two children’s hospitals

Purpose

Widespread adoption of minimally invasive surgery (MIS) techniques in pediatric surgery has progressed slowly, and the shift in practice patterns has been variable among surgeons. We hypothesized that a pediatric surgeon committed to MIS could effectively change surgical practice by creating an emphasis on MIS.

Methods

Annual case volumes from 2000 to 2009 at two tertiary care pediatric hospitals, one with a dedicated minimally invasive pediatric surgeon, were evaluated for trends in MIS for ten different operations. Univariate analyses of the differences between hospitals in the use of the open versus laparoscopic approach were performed. The Breslow–Day test was used to examine differences in use of laparoscopic procedures across hospitals in early versus middle and middle versus late time periods.

Results

Between the two hospitals, for 9 of the 10 types of surgery, the number of laparoscopic and open procedures differed significantly (p values ranged from <0.0001 to 0.003). Over the 10-year period, the hospital with a dedicated MIS surgeon had a larger proportion of procedures done laparoscopically for all years. This difference reached statistical significance for appendectomy (p < 0.0001), congenital diaphragmatic hernia (p < 0.0002), chest wall reconstruction (p < 0.0001), cholecystectomy (p = <0.0001), gastrostomy (p < 0.0001), nissen fundoplication (p < 0.0001) oophorectomy (p < 0.0001), pyloromyotomy (p < 0.0001) and splenectomy (p = 0.0006). After grouping the years into early (2000–2003), middle (2004–2006) and late (2007–2009) categories, the hospital with a dedicated MIS surgeon had a significantly higher rate of increase in use of laparoscopic surgery between the early and middle years for four procedures: diaphragmatic hernia repair (p = 0.003), chest wall reconstruction (p = 0.0086), cholecystectomy (0.0083) and endorectal pull-through (p = 0.025).

Conclusion

The presence of a dedicated minimally invasive pediatric surgeon led to a significant change in surgical practice with an overall trend of increasing MIS several years in advance of a hospital that did not have a dedicated MIS surgeon. This has implications for resident training in academic medical centers and potential patient care outcomes.

     

Prospective cohort study on surgeons’ response to equipment failure in the laparoscopic environment

Background

Equipment malfunction accounts for approximately one-fourth of surgical errors in the operating room. A serious game was developed to train surgeons in recognizing and responding to equipment failure in minimally invasive surgery (MIS) adequately. This study determined the baseline performance of surgeons, surgical residents, surgical novices, and MIS equipment technicians in solving MIS equipment failure.

Methods

The serious game included 37 problem scenarios on the subjects lighting and imaging, insufflation and gas transport, electrosurgery, and pathophysiological disturbances. The scenarios were validated by laparoscopic surgeons and MIS equipment specialists. Forty-nine licensed surgeons, surgical residents, medical students, and MIS equipment specialists played four sessions on the serious game at a surgical convention. Scores on different outcome parameters were compared between groups of a different MIS experience.

Results

Laparoscopic equipment specialists solved significantly more MIS equipment-related problems than surgical novices, intermediates, and experts (68.9 vs. 51.0 %, 51.4, and 45.0 %, respectively, p = 0.01). Laparoscopic equipment specialists required significantly fewer steps to solve a problem accurately (median of 1.0 vs. 2.0 for the other groups). Most notably, experienced surgeons were unable to outperform novice and intermediate groups. Experienced surgeons took less time to solve the problems, but made more mistakes in doing so.

Conclusions

Experienced surgeons did not outperform inexperienced surgeons in dealing with laparoscopic equipment failure. These results are worrying and need to be addressed by the surgical community.     

Measuring Global Surgical Disparities: A Survey of Surgical and Anesthesia Infrastructure in Bangladesh

Background

Surgically treatable diseases weigh heavily on the lives of people in resource-poor countries. Though global surgical disparities are increasingly recognized as a public health priority, the extent of these disparities is unknown because of a lack of data. The present study sought to measure surgical and anesthesia infrastructure in Bangladesh as part of an international study assessing surgical and anesthesia capacity in low income nations.

Methods

A comprehensive survey tool was administered via convenience sampling at one public district hospital and one public tertiary care hospital in each of the seven administrative divisions of Bangladesh.

Results

There are an estimated 1,200 obstetricians, 2,615 general and subspecialist surgeons, and 850 anesthesiologists in Bangladesh. These numbers correspond to 0.24 surgical providers per 10,000 people and 0.05 anesthesiologists per 10,000 people. Surveyed hospitals performed a large number of operations annually despite having minimal clinical human resources and inadequate physical infrastructure. Shortages in equipment and/or essential medicines were reported at all hospitals and these shortages were particularly severe at the district hospital level.

Conclusions

In order to meet the immense demand for surgical care in Bangladesh, public hospitals must address critical shortages in skilled human resources, inadequate physical infrastructure, and low availability of equipment and essential medications. This study identified numerous areas in which the international community can play a vital role in increasing surgical and anesthesia capacity in Bangladesh and ensuring safe surgery for all in the country.     

The First Decade of Laparoscopic Pancreaticoduodenectomy in the United States: Costs and Outcomes Using the Nationwide Inpatient Sample

Background

Minimally invasive pancreaticoduodenectomy (PD) remains an uncommon procedure, and the safety and efficacy remain uncertain beyond single institution case series. The aim of this study is to compare outcomes and costs between laparoscopic (LPD) and open PD (OPD) using a large population-based database.

Methods

The Nationwide Inpatient Sample database (a sample of approximately 20 % of all hospital discharges) was analyzed to identify patients who underwent PD from 2000 to 2010. Patient demographics, comorbidities, hospital characteristics, inflation-adjusted total charges, and complications were evaluated using univariate and multivariate logistic regression. Hospitals were categorized as high-volume hospitals (HVH) if more than 20 PD (open and laparoscopic) were performed annually, while those performing fewer than 20 PD were classified as low-volume hospitals.

Results

Of the 15,574 PD identified, 681 cases were LPD (4.4 %). Compared to OPD, patients who underwent LPD were slightly older (65 vs. 67 years; p = 0.001) and were more commonly treated at HVH (56.6 vs. 66.1 %; p < 0.001). Higher rates of complications were observed in OPD than LPD (46 vs. 39.4 %; p = 0.001), though mortality rates were comparable (5 vs. 3.8 %, p = 0.27). Inflation-adjusted median hospital charges were similar between OPD and LPD ($87,577 vs. $81,833, p = 0.199). However, hospital stay was slightly longer in the OPD group compared to LPD group (12 vs. 11 days, p < 0.001). Stratifying outcomes by hospital volume, LPD at HVH resulted in shorter hospital stays (9 vs. 13 days, p < 0.001), which translated into significantly lower median hospital charges ($76,572 vs. $106,367, p < 0.001).

Conclusions

Contrary to fears regarding the potential for compromised outcomes early in the learning curve, LPD morbidity in its first decade is modestly reduced, while hospital costs are comparable to OPD. In high-volume pancreatic hospitals, LPD is associated with a reduction in length of stay and hospital costs.

This study aimed to seek the opinions of academic surgical chairs on minimally invasive surgery (MIS) education for general surgery residents and to identify perceived gaps and trends in educational strategies.     

National trends and disparities of minimally invasive surgery for localized renal cancer, 2010 to 2015

Purpose

To investigate national utilization trends of minimally-invasive partial nephrectomy (PN) and minimally-invasive radical nephrectomy (RN), and to identify disparities in the usage of these techniques across different sociodemographic subgroups.

Comparative Outcomes of Minimally Invasive Surgery for Posterior Lumbar Fusion: A Systematic Review

Background

Although minimally invasive surgical (MIS) approaches to the lumbar spine for posterior fusion are increasingly being utilized, the comparative outcomes of MIS and open posterior lumbar fusion remain unclear.

Questions/purposes

In this systematic review, we compared MIS and open transforaminal or posterior lumbar interbody fusion (TLIF/PLIF), specifically with respect to (1) surgical end points (including blood loss, surgical time, and fluoroscopy time), (2) clinical outcomes (Oswestry Disability Index [ODI] and VAS pain scores), and (3) adverse events.

Methods

We performed a systematic review of MEDLINE^®, Embase, Web of Science, and Cochrane Library. Reference lists were manually searched. We included studies with 10 or more patients undergoing MIS compared to open TLIF/PLIF for degenerative lumbar disorders and reporting on surgical end points, clinical outcomes, or adverse events. Twenty-six studies of low- or very low-quality (GRADE protocol) met our inclusion criteria. No significant differences in patient demographics were identified between the cohorts (MIS: n = 856; open: n = 806).

Results

Equivalent operative times were observed between the cohorts, although patients undergoing MIS fusion tended to lose less blood, be exposed to more fluoroscopy, and leave the hospital sooner than their open counterparts. Patient-reported outcomes, including VAS pain scores and ODI values, were clinically equivalent between the MIS and open cohorts at 12 to 36 months postoperatively. Trends toward lower rates of surgical and medical adverse events were also identified in patients undergoing MIS procedures. However, in the absence of randomization, selection bias may have influenced these results in favor of MIS fusion.

Conclusions

Current evidence examining MIS versus open TLIF/PLIF is of low to very low quality and therefore highly biased. Results of this systematic review suggest equipoise in surgical and clinical outcomes with equivalent rates of intraoperative surgical complications and perhaps a slight decrease in perioperative medical complications. However, the quality of the current literature precludes firm conclusions regarding the comparative effectiveness of MIS versus open posterior lumbar fusion from being drawn and further higher-quality studies are critically required.     

Is the use of minimally invasive fusion technologies associated with improved outcomes after elective interbody lumbar fusion? Analysis of a nationwide prospective patient-reported outcomes registry

Background Context

Over the last decade, clinical investigators and biomedical industry groups have used significant resources to develop advanced technologies that enable less invasive spine fusions. These minimally invasive surgery (MIS) technologies often require increased expenditures by hospitals and payers. Although several small single center studies have suggested MIS technologies decrease surgical morbidity and reduce hospital stay, evidence documenting benefit from a patient perspective remains limited. Furthermore, MIS outcomes have yet to be evaluated from the perspective of multiple practice types representing the broad spectrum of US spine surgery.

Does robotic assistance improve efficiency in performing complex minimally invasive surgical procedures?

Objective  

We used a model of biliary-enteric anastomosis to test whether da Vinci robotics improves performance on a complex minimally invasive surgical (MIS) procedure.     

Malpractice carrier underwrites Fundamentals of Laparoscopic Surgery training and testing: a benchmark for patient safety

Background  

Fundamentals of Laparoscopic Surgery (FLS) is a validated program developed by the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) to educate and assess competency in minimally invasive surgery (MIS). This study reports the first malpractice carrier–sponsored FLS course for surgeons in practice underwritten by the Controlled Risk Insurance Company of Harvard’s Risk Management Foundation (CRICO/RMF). The study investigated the participating surgeons’ pattern of MIS skills acquisition, subjective laparoscopic comfort level, operative activity, and perception of the FLS role in surgical education, credentialing, and patient safety.     

Retrospective multicenter study of surgical treatments for osteoporotic vertebral fractures

Background  

Although many surgical procedures are available for treating osteoporotic vertebral fractures, there have been no comprehensive multicenter surveys in Japan focusing on surgical treatments for these fractures. This study aimed at (1) conducting a retrospective multicenter study to survey surgical treatments performed at referral center hospitals in various regions in Japan and (2) analyzing situations and problems related to the surgical treatments of osteoporotic vertebral fractures in Japanese hospitals.
