Is newer always better?: comparing cost and short-term outcomes between laparoscopic and robotic right hemicolectomy.

BACKGROUND: Enthusiasm is high for expansion of robotic assisted surgery into right hemicolectomy. But data on outcomes and cost is lacking. Our objective was to determine the association between surgical approach and cost for minimally invasive right hemicolectomy. We hypothesized that a robot approach would have increased costs (both economic and opportunity) while achieving similar short-term outcomes. METHODS: We performed a retrospective cohort analysis with a simulation of operating room utilization at a quaternary care, academic institution. We enrolled patients undergoing minimally invasive right hemicolectomy from November 2017 to August 2019. Patients were categorized by the intended approach- laparoscopic or robotic. The primary outcome was the technical variable direct cost. Secondary outcomes included total cost, supply cost, operating room utilization, operative time, conversion, length of stay and 30-day post-operative outcomes. RESULTS: 79 patients were included in the study. A robotic approach was used in 22% of the cohort. The groups differed significantly only in etiology of surgery. Robotic surgery was associated with a 1.5 times increase in the technical variable direct cost (p < 0.001), increased supply cost (2.6 times; p < 0.001) and increased total cost (1.3 times; p < 0.001). Significant differences were observed in median room time (Robotic: 285 min vs. Laparoscopic: 170 min; p < 0.001) and procedure time (Robotic: 203 min vs. Laparoscopic: 118 min; p < 0.001). There were no differences observed in post-operative outcomes including length of stay or readmission. In a simulation of OR utilization, 45 laparoscopic right hemicolectomies could be performed in an OR in a month compared to 31 robotic cases. CONCLUSIONS: Robotic right hemicolectomy was associated with increased costs with no improvement in post-operative outcomes. In a simulation of operating room efficiency, a robotic approach was associated with 14 fewer cases per month. Practitioners and administrators should be aware of the increased cost of a robotic approach.

Barriers to laparoscopic colon resection for cancer: a national analysis.

BACKGROUND: Level one evidence has shown that minimally invasive surgery (MIS) for colon cancer improves short-term outcomes with equivalent long-term oncologic results when compared to open surgery. However, the adoption of MIS for patients with colon cancer has not been universal. The goal of this study is to identify barriers to the use of MIS surgery in colon cancer resection across the United States. METHODS: The National Cancer Database was queried for all cases of colonic adenocarcinoma resection from 2010 to 2012. Patients undergoing an MIS approach were compared with those undergoing open surgery (OS). MIS was defined as either robotic or laparoscopic surgery. Patients with metastatic disease, surgery for palliation, or tumors >8 cm were excluded. Multivariable modeling was used to identify variables associated with the use of open surgery. RESULTS: After applying exclusion criteria, 124,205 cases were identified. An MIS approach was used in only 54,621 (44%) patients. In a multivariable model adjusting for stage and tumor size, a number of important factors were associated with decreased odds of a MIS approach including black race (OR .91; p < .0001), lack of insurance (OR .51; p < .0001), lower education (OR .88; p < .0001), lower income (OR .83; p < .0001), treatment at a community program (OR .86; p < .0001), and treatment at a low-volume center (OR .79; p < .0001). Utilization of MIS increased over the study period (2010: 38.7%, 2011: 44.0%, 2012: 49.1%; p < .0001). CONCLUSIONS: MIS approach is utilized in less than half of all colon resections in this national database, which accounts for over 70% of all diagnosed cancers in the US. Significant variability exists among age, race, insurance status, socioeconomic status, region, and facility type. In light of the recognized benefits of the MIS approach, local and national policy should focus on narrowing these disparities and continuing the upward trend of MIS utilization.

The adaptive metabolic response to exercise-induced weight loss influences both energy expenditure and energy intake.

BACKGROUND/OBJECTIVES: A decline in resting energy expenditure (REE) beyond that predicted from changes in body composition has been noted following dietary-induced weight loss. However, it is unknown whether a compensatory downregulation in REE also accompanies exercise (EX)-induced weight loss, or whether this adaptive metabolic response influences energy intake (EI). SUBJECTS/METHODS: Thirty overweight and obese women (body mass index (BMI)=30.6±3.6 kg/m(2)) completed 12 weeks of supervised aerobic EX. Body composition, metabolism, EI and metabolic-related hormones were measured at baseline, week 6 and post intervention. The metabolic adaptation (MA), that is, difference between predicted and measured REE was also calculated post intervention (MApost), with REE predicted using a regression equation generated in an independent sample of 66 overweight and obese women (BMI=31.0±3.9 kg/m(2)). RESULTS: Although mean predicted and measured REE did not differ post intervention, 43% of participants experienced a greater-than-expected decline in REE (-102.9±77.5 kcal per day). MApost was associated with the change in leptin (r=0.47; P=0.04), and the change in resting fat (r=0.52; P=0.01) and carbohydrate oxidation (r=-0.44; P=0.02). Furthermore, MApost was also associated with the change in EI following EX (r=-0.44; P=0.01). CONCLUSIONS: Marked variability existed in the adaptive metabolic response to EX. Importantly, those who experienced a downregulation in REE also experienced an upregulation in EI, indicating that the adaptive metabolic response to EX influences both physiological and behavioural components of energy balance.

External quality assessment of human neutrophil antigen (HNA)-specific antibody detection and HNA genotyping from 2000 to 2012.

Since 2000, Quality Assurance (QA) exercises for the detection and identification of granulocyte antibodies and DNA typing for human neutrophil antigens (HNA) have been distributed within the International Granulocyte Immunobiology Workshops, which are linked to International Society of Blood Transfusion. The exercises were standardised at the outset to enable laboratory performance to be monitored. Between 2000 and 2012, nine exercises were distributed to 20 laboratories. Overall, 45 examples of 42 unique samples containing defined granulocyte reactive antibodies were distributed for serological analysis together with 20 samples for HNA genotyping. The level of satisfactory serological performance was initially set at 50% and later increased to 70%, while the 'cut-off' for HNA genotyping was set at 100% after 2008. Failure to achieve the minimum score in the QA exercises in consecutive years resulted in temporary exclusion. In 2000, the 15 participating laboratories had a mean score of 56.1% for serological analysis and 13 laboratories attempted HNA-1a and -1b genotyping, while 11 attempted HNA-1c typing. Steady improvements in proficiency for serological testing and HNA typing occurred in subsequent exercises. In 2012, the mean score for serology was 88.5% and 12/13 laboratories scored 100% for HNA-1a, -1b, -1c, -3a, -3b, -4a, -4bw, -5a and -5bw genotyping. These QA exercises have provided an invaluable tool to monitor and improve the standard of granulocyte immunology investigations for participating laboratories, thereby enhancing performance for both clinical investigations and donor screening programmes to reduce the incidence of TRALI.

Cancer antigen 125 in ovarian cancer surveillance: a decision analysis model.

We used decision analysis techniques with Markov cohort modeling to examine the role of cancer antigen 125 (CA-125) in follow-up surveillance strategies among patients with advanced ovarian cancer. Utilities were derived from a societal perspective.Using quality-adjusted life years (QALYS) as the outcome variable, the value of CA-125 monitoring for asymptomatic women with ovarian cancer was found to be reduced as compared with a strategy that includes CA-125 testing. Decisions to include CA-125 in surveillance strategies for ovarian cancer patients should be made after discussion with full disclosure of the preference-sensitive nature of CA-125. The model demonstrates that preferences and perspective can influence decisions in cancer care.

Reducing fluxes of faecal indicator compliance parameters to bathing waters from diffuse agricultural sources: the Brighouse Bay study, Scotland.

The European Water Framework Directive requires the integrated management of point and diffuse pollution to achieve 'good' water quality in 'protected areas'. These include bathing waters, which are regulated using faecal indicator organisms as compliance parameters. Thus, for the first time, European regulators are faced with the control of faecal indicator fluxes from agricultural sources where these impact on bathing water compliance locations. Concurrently, reforms to the European Union (EU) Common Agricultural Policy offer scope for supporting on-farm measures producing environmental benefits through the new 'single farm payments' and the concept of 'cross-compliance'. This paper reports the first UK study involving remedial measures, principally stream bank fencing, designed to reduce faecal indicator fluxes at the catchment scale. Considerable reduction in faecal indicator flux was observed, but this was insufficient to ensure bathing water compliance with either Directive 76/160/EEC standards or new health-evidence-based criteria proposed by WHO and the European Commission.

Parathyroid hormone secretory pattern, circulating activity, and effect on bone turnover in adult growth hormone deficiency.

Adult growth hormone deficiency (AGHD) is associated with osteoporosis. Reports have associated parathyroid hormone (PTH) circadian rhythm abnormalities with osteoporosis. Furthermore, there is evidence of relative PTH insensitivity in AGHD patients. Factors regulating PTH circadian rhythm are not fully understood. There is evidence that serum phosphate is a likely determinant of PTH rhythm. The aim of this study was to investigate PTH circadian rhythm and its circulating activity and association with bone turnover in untreated AGHD patients compared to healthy individuals. We sampled peripheral venous blood at 30-min and urine at 3-h intervals during the day over a 24-h period from 1400 h in 14 untreated AGHD patients (7 M, 7 W; mean age, 49.5 +/- 10.7 years) and 14 age (48.6 +/- 11.4 years; P = NS) and gender-matched controls. Cosinor analysis was performed to analyze rhythm parameters. Cross-correlational analysis was used to determine the relationship between variables. Serum PTH (1-84), phosphate, total calcium, urea, creatinine, albumin, type I collagen C-telopeptides (CT(x)), a bone resorption marker, and procollagen type I amino-terminal propeptide (PINP), a bone formation marker, were measured on all samples. Nephrogenous cyclic adenosine monophosphate (NcAMP), which reflects the renal activity of PTH, was calculated from plasma and urinary cAMP. Urinary calcium and phosphate were measured on all urine samples. Significant circadian rhythms were observed for serum PTH, phosphate, CT(x), and PINP in AGHD and healthy subjects (P < 0.001). No significant rhythm was observed for serum-adjusted calcium. PTH MESOR (rhythm-adjusted mean) was significantly higher (P < 0.05), whereas the MESOR values for phosphate, CT(x) (P < 0.05), and PINP (P < 0.001) were lower in AGHD patients than in controls. AGHD patients had significantly lower 24-h NcAMP (P < 0.001) and higher urinary calcium excretion (P < 0.05). Maximum cross-correlation between PTH and phosphate (r = 0.75) was observed when PTH was lagged by 1.5 h in healthy individuals, suggesting that changes in phosphate precede changes in PTH concentration. PTH/CT(x) and PTH/PINP showed maximum correlation when CT(x) (r = 0.68) and PINP (r = 0.71) were lagged by 3 h. In AGHD patients, compared to controls the maximum correlation between PTH/phosphate (r = 0.88, P = 0.007), PTH/CTx (r = 0.61, P = 0.027), and PTH/PINP (r = 0.65, P = 0.028) was observed when the lag time was reduced by 1.5 h in all variables, with changes in PTH and phosphate occurring at concurrent time points. Our data suggest decreased end-organ sensitivity to the effects of PTH in AGHD patients, resulting in a significantly lower NcAMP, low bone turnover, and higher calcium excretion in the presence of significantly higher PTH concentrations. We have also demonstrated that changes in serum phosphate precede those of PTH, which in turn precede changes in bone resorption and formation in healthy individuals. This relationship was altered in AGHD patients. These results suggest a possible role for GH in regulating PTH secretion and the bone remodeling process.

A comparison of complementary and alternative medicine use by gynecology and gynecologic oncology patients.

Our objective was to describe and compare the use of complementary and alternative medicine (CAM) in gynecology and gynecological oncology patients. Five hundred and twenty-nine gynecology and gynecological oncology patients completed a questionnaire regarding CAM use. Overall, 56.3% of gynecology and gynecological oncology patients reported current use of CAM. Therapies used included nutritional supplements (20%), prayer as medical therapy (17%), exercise as medical therapy (12%), megavitamins (10%), and green tea (10%). While 69.5% believed CAM to be beneficial, only 31.6% discussed these therapies with their physician. The women spent a mean of $656.22 on CAM (range $0-$7,000), with 31.7% receiving some insurance reimbursement. Gynecologic oncology patients (n = 161) used CAM significantly more than gynecology patients (n = 368) (66% vs. 52%, 95% CI = 0.046-0.230, P = 0.004). Gynecological oncology patients also spent more for CAM, with a mean expenditure of $711 versus $622 by gynecology patients. Within the gynecological oncology patient group, there were 69 patients currently receiving modern medical treatments for cancer; among these patients, 58% reported using CAM; of these, 39.3% communicated their use of CAM to their physician. Patients in this group spent an average of $1,178 on CAM during their illness, with only 6.3% receiving insurance reimbursement. Benefits from CAM were perceived by 54.5% in this group. We concluded that cancer patients have a higher usage rate and expenditure for CAM, particularly while they are receiving medical therapy, and are more likely to discuss the use of alternative therapies with their physicians. CAM was perceived as helpful by patients despite the lack of scientific data about its effect.

The myths of laparoscopic surgery.

Laparoscopic surgery has been rapidly accepted without rigorous scientific study. New procedures and technologies have advanced rapidly, and most gynecologists have embraced these techniques. I believe that the new technology has given rise to the following myths: (1) that there are associated cost savings, (2) that new technology is always better than the old, (3) that a steep learning curve is acceptable, (4) that market share will be lost without the new techniques, (5) that oncologic surgery is not different when performed laparoscopically, (6) that operations are the same with the laparoscope, and (7) that every gynecologist can do these procedures. A critical evaluation of new technology and of laparoscopic techniques needs to be performed.

Subacute care: which patients benefit?

The decision about appropriate referral of patients to a subacute care unit is the key to both continuity of care and the financial viability of a hospital's subacute care unit. Patient selection, subacute care admission criteria, patient education, and financial concerns are discussed.

Value in health care: what providers and employers say.

Earlier this year, two surveys were conducted among healthcare providers and employers seeking their opinions regarding strategies they would employ to deal with current and expected cost pressures of the healthcare marketplace as well as healthcare value. The results of the surveys suggest that providers and employers may not be seeing the issues the same way. Providers that partner with employers will be the organizations best able to improve the quality of the care delivered--and boost their competitive positions--while the employers will receive greater value for their healthcare dollars.

Psychosocial factors as predictors of length of stay of Medicare patients under the prospective payment system.

The Prospective Payment System methodology is designed to predict inpatient hospital resource utilization. The system sets standards based on medical diagnosis (Diagnosis Related Groups), but it ignores psychosocial characteristics which often determine discharge options and therefore, directly affect a patient's length of stay. A study is described which examined the psychosocial characteristics of 234 elderly hospitalized patients in relation to length of stay and route of admission (elective or emergency room). Such data can be very useful to discharge planners in identifying high social risk patients, as well as to health planners attempting to modify the DRG methodology to incorporate psychosocial factors.

An assessment of pathologic features and treatment modalities in ovarian tumors of low malignant potential.

Sixty-eight patients with epithelial ovarian tumors of low malignant potential treated at the University of Michigan Medical Center were reviewed for clinical and pathologic features related to recurrence or death. The ovarian tumor of low malignant potential represented 12.6% of all ovarian cancers and 22% of all serous or mucinous tumors. Thirty-four patients were stage I (50%), 13 were stage II (19%), 17 were stage III (25%), two patients could not be staged, and two patients developed ovarian tumor of low malignant potential in a residual ovary. The risk of recurrence was significantly related to stage III disease (P = .023), high nuclear atypia (P = .020), and high grade (P = .017); and was unrelated to capsular status, the presence of psammoma bodies, nucleoli, cribriform pattern, stratification, cystadenofibroma, tumor size, or spillage at surgery. Therapy in all stages included observation, chemotherapy, or radiotherapy. There was one recurrence in 47 patients with stages I-II, and 11 recurrences in 17 patients with stage III disease. The ovarian tumor of low malignant potential carries an extremely favorable prognosis in stage I and II regardless of therapy. Radiotherapy appeared to extend disease-free survival in stage III disease, and future randomized studies should consider this treatment modality.

Managed care plans: CFOs weigh the benefits.

Managed health care is one of the biggest changes to occur in the healthcare industry. It has also had one of the greatest effects on the financial viability of hospitals. By the year 2000, it is expected that 70 percent of insurance premiums will be paid to some sort of capitated managed care plan as opposed to traditional insurance. With the arrival of managed care plans comes many questions for hospital CFOs. To answer these questions and gain an understanding of how different organizations are coping with managed health care, a survey of hospital CFOs was conducted. It was concluded that managed care is definitely here to stay. While CFOs feel there are risks involved, managed care plans are an area that will provide the greatest opportunity for organizational growth.

Evaluating a basic-needs strategy and population policies: the BACHUE approach.

PIP: The BACHUE model, a dynamic simulation technique developed within the International Labour Organization's World Employment Program, has been applied to the Philippines. The model simulates behavior and consequences in a number of key areas: fertility, marriage, migration, savings and expenditure, and labor force participation for households and a macro-model for demand, ouput, employment, and income. The design and development of the model are discussed in detail. The model was run for a series of 13 experiments ranging from nationlization of modern sectors, increasing self-employment, movement toward labor-intensive techniques, changes in growth rates of various sectors, and a reduction in fertility by 2% over 1976-1985, an increase over the 1% assumed in the base run. Runs R-2 to R-11 all showed that a change in basic needs is associated with significant declines in fertility, largely because of increasing education and decreasing mortality. Better economic conditions in rural areas also reduced migration. R-13 which examined the effects of a family planning program of moderate size on ultimate fertility, showed that even by year 2000 the effects were small. The population is reduced 5% over the run which assumes negative income tax and government subsidies to poor families but the gain in income per adult is less than 4%. Any real improvement in income as the result of family planning will take 40-50 years to achieve. Economic incentives, on the other hand, have much faster demographic results. The models also show that rural-urban migration is responsive to policy changes. Planners are cautioned that the model is not a picture of the entire range of human behavior but is an adjunct for use in analyzing interaction between policies.^ieng
