Surgical Data

To evaluate surgeons’ performance, health care managers often use the revenues that surgeons make for the hospital. The purpose of this study is to determine the relationship between surgeons’ technical efficiency and their revenues by using multiple regression analysis on surgical data. The authors collected data from all the surgical procedures performed at University Hospital from April 1 through September 30 in 2013-2018. Output-oriented Charnes-Cooper-Rhodes model of data envelopment analysis was employed to calculate each surgeon’s technical efficiency. Seven independent variables were selected; revenue, experience, medical school, surgical volume, sex, academic rank, and surgical specialty. Multiple regression analysis using Tobit model was used for our data. The data from a total of 17 227 surgical cases were obtained in the 36-month study period. The authors performed multiple regression on 222 surgeons. Revenue had significantly positive association with mean efficiency score ( P = .000). Surgical volume had significantly negative association with mean efficiency score ( P = .000). The other coefficients were statistically insignificant. An increase in revenue by 1% was associated with 0.46% to 0.52% increases in efficiency score. We demonstrated that surgeons’ revenue can serve as a proxy variable for their technical efficiency.

Adequate Sedation

Sedation may minimize physiologic and behavioral stress responses. In our facility, the infusion rate of propofol is adjusted according to the bispectral index (BIS) in all cases of implant-related surgery; multivariate analysis of retrospective data enabled us to extract independent factors that affect the dose of propofol in sedation that are considered useful indicators for achieving adequate sedation. The study population comprised all patients undergoing implant-related surgery under intravenous sedation in Okayama University Hospital from April 2009 to March 2013. The infusion rate of propofol was adjusted to maintain the BIS value at 70–80. The outcome was the average infusion rate of propofol, and potential predictor variables were age, sex, body weight, treatment time, and amount of midazolam. Independent variables that affected the average infusion rate of propofol were extracted with multiple regression analysis. One hundred twenty-five subjects were enrolled. In the multiple regression analysis, female sex was shown to be significantly associated with a higher average infusion rate of propofol. Females may require a higher infusion rate of propofol than males to achieve adequate sedation while undergoing implant-related surgery.

The sustainability of the Japanese healthcare system is questionable because of a huge fiscal debt. One of the solutions is to improve the efficiency of healthcare. The purpose of this study is to determine what factors are predictive of surgeons’ efficiency scores. The authors collected data from all the surgical procedures performed at Teikyo University Hospital from April 1 through September 30 in 2013–2015. Output-oriented Charnes-Cooper-Rhodes model of data envelopment analysis was employed to calculate each surgeon’s efficiency score. Seven independent variables that may predict their efficiency scores were selected: experience, medical school, surgical volume, gender, academic rank, surgical specialty, and the surgical fee schedule. Multiple regression analysis using random-effects Tobit model was used for our panel data. The data from total 8722 surgical cases were obtained in 18-month study period. The authors analyzed 134 surgeons. The only statistically significant coefficients were surgical specialty and surgical fee schedule (p = 0.000 and p = 0.016, respectively). Experience had some positive association with efficiency scores but did not reach statistical significance (p = 0.062). The other coefficients were not statistically significant. These results demonstrated that the surgical reimbursement system, not surgeons’ personal characteristics, is a significant predictor of surgeons’ efficiency.

Abstract Background The purpose of this study is to examine how the degree of inequality of Japanese surgical fee schedule changed during the study period by applying Gini coefficients for efficiency scores computed from data envelopment analysis. Methods All the surgeries that were performed in the main operating rooms of Teikyo University Hospital in 2013-18 were candidates used for the analysis of efficiency and equality of fee schedule. The decision making unit was defined as a surgeon with the highest academic rank in the surgery. Inputs were defined as (1) the number of assistants, and (2) the duration of operation. An output was defined as the surgical fee that was charged for reimbursement. Each surgeon’s efficiency score was calculated using data envelopment analysis. Using the medians of efficiency scores in each surgical specialty, the authors inferred Gini coefficients and their standard errors in each year and in each surgical fee schedule by the Bootstrap methods. Results The authors analyzed 16,307 surgical procedures during the study period of 2013-18. There was no statistically significant difference in the Gini coefficients between the years and between the surgical fee schedules (p > 0.05). Conclusions The authors demonstrated that the degree of inequality of Japanese surgical fee schedule remained constant from 2013 through 2018.

Background and Purpose: Unilateral spatial neglect (USN) is often observed in ischemic stroke patients suffered their right parietal lobe. USN is an obstacle to undergo rehabilitation smoothly, then might influence the recovery of activities of daily living (ADL) after stroke. We aimed to clarify the association between the presence of USN after ischemic stroke and the ADL improvement. Methods: Consecutive patients with first-ever ischemic stroke and left limb paralysis who admitted to within 7 days from onset during February 2011 and March 2019 were included. Patients met the following criteria were excluded: mRS ≥3 before onset, NIHSS >15 on admission, without left limb paralysis, and missing NIHSS or functional independence measure (FIM) score on admission. Multiple regression analysis was performed to investigate the association between FIM efficiency score of acute phase and following factors: age, sex, acute reperfusion therapy (using an intravenous infusion of recombinant tissue plasminogen activator and/or endovascular therapy), FIM score on admission, and other clinical characteristics. All data were collected retrospectively using our electrical health record. Results: 721 ischemic stroke patients with left limb paralysis (320 women, median age 76) were included. Median FIM efficiency score was significantly lower in patients with USN than without USN (n=240, 481; 0.83 vs 1.63, respectively). Multiple regression analysis showed that USN, age, and acute reperfusion therapy were significant prognostic factors of FIM efficiency (coefficient and 95% confidence interval [CI]: -0.135 [-0.771 to -0.153], -0.106 [-0.022 to -0.002], and 0.224 [0.136 to 0.305], respectively). Conclusions: USN significantly influence the recovery of ADL after ischemic stroke. Clinicians should adequately evaluate USN after stroke and undergo USN-specific rehabilitation for them to optimize the effect of post-stroke rehabilitation. USN-specific rehabilitation might lead to better FIM efficiency.

Seaweed-Kappaphycus-Euchema Cottonii and Denticulum species was first cultivated at Sabah side of Sebatik in 2009. By November 2014, sixty one Sabahan seaweed farmers cultivated 122 ha or 3,050 long lines. Thirty Sabahan seaweed farmers in Kampung Pendekar (3.2 m.t dried) and 31 in Burst Point (12.5 m.t dried) produced 16 metric tonnes of dried seaweed contributed 31% to Tawau’s total production (51 m.t). The remaining 69% were from farmers in Cowie Bay that separates Sebatik from municipality of Tawau. Indonesian in Desa Setabu, Sebatik started in 2008. However, the number of Indonesian seaweed farmers, their cultivated areas and production (as well as quality) in Sebatik increased many times higher and faster than the Sabah side of Sebatik. In 2009 more than 1,401 households in Kabupaten Nunukan (including Sebatik) cultivated over 700 ha and have produced 55,098.95 and 116, 73 m.t dried seaweed in 2010 and 2011 respectively. There is a divergence in productions from farming the sea off the same island under similar weather conditions. Which of the eight explanatory factors were affecting production of seaweeds in Sebatik? Using Cobb Douglas production function, Multiple Regression analysis was conducted on 100 samples (50 Sabahan and 50 Indonesian). Results; Variable significant at α = 0.05% are Experience in farming whereas Farm size; Quantity of propagules and Location — Dummy are the variables significant at α 0.01%. Not significant are variables Fuel; Age; Number of family members involved in farming and Education level.
