Pre- and intra-operative predictors of postoperative hospital length of stay in patients undergoing radical prostatectomy for prostate cancer in China: a retrospective observational study

Effect of Early Postoperative Rehabilitation on Length of Hospital Stay after Robot-assisted Radical Prostatectomy

Objectives

: This study assessed how early postoperative rehabilitation interventions affected the duration of hospital stay in patients with prostate cancer who had radical prostatectomy with robotic assistance.

Methods

: From the Japanese Diagnosis Procedure Combination database, we extracted case data for patients discharged between April 2014 and March 2020. Patients were recognized by code C61 from the International Classification of Diseases, 10th Edition. We ran a multilevel linear regression analysis to investigate the impact of early rehabilitation on the duration of hospital stay.

Results

: There were 2151 participants in the trial. In patients with prostate cancer who had resection utilizing robotic-assisted devices, early rehabilitation was related to a substantial decrease in duration of hospital stay (coefficient, -0.86; 95% CI, -1.64 to -0.07; P=0.032).

Conclusions

: Early postoperative rehabilitation may contribute to shorter hospital stays in patients with prostate cancer at high risk of both postoperative complications and a decline in their ability to perform activities of daily living.

Postoperative Effect Observation and Clinical Study of Dahuang Zhechong Pills from Jingui Yaolue in Treating Patients with Early-to-Mid Prostate Cancer Undergoing Radical Resection

Objective

To explore the effect of applying Dahuang Zhechong pills (DHZCP) from Jingui Yaolue to patients with early-to-mid prostate cancer undergoing radical resection and carry out a theoretical clinical study of traditional Chinese medicine (TCM) to verify the effect of DHZCP formula under the guidance of TCM theory.

Methods

The clinical data of 98 patients with early-to-mid prostate cancer undergoing radical resection treated in our hospital (July 2014 to July 2016) were selected for the retrospective analysis, and the patients were divided into group A (n = 49, routine hormonal therapy) and group B (n = 49, routine hormonal therapy plus DHZCP) according to the double blind method, so as to compare the trauma symptoms, cancer recurrence rate, etc., after treatment between the two groups.

Results

Compared with group A, group B obtained significantly higher total effective rate of complication treatment at different time points (P < 0.05), significantly lower mean HAMA score after treatment (P < 0.05), and significantly lower total recurrence rate (P < 0.05). The "congestion" theory in Chapter VI On Pulse, Symptom Complex and Treatment of Arthralgia Due to Stagnation of Blood and Consumptive Diseases of Jingui Yaolue was the theoretical basis for postoperative effect observation of DHZCP in treating prostate cancer. Combining with the onset theory of congestion, personally, the author believed that cancer is caused by congestion disease formed by the extravasated blood in the human body, and with the passing of time, the intermingled deficiency, blood stasis, and toxicity lead to the qualitative change of endogenous cancer toxicity and develop into consumptive congestion disease, making it the core pathogenesis of cancer. And DHZCP had good preventive and treatment effect.

Conclusion

DHZCP is an effective drug for improving postoperative complications of early-to-mid prostate cancer, reducing the biological recurrence rate and clinical recurrence rate, and improving mental status. The formula treats both deficiency and excess, combines tonification with purgation, and dispels exogenous pathogen without damaging body resistance, which is a profound formula based on TCM theory to treat "congestion," "congestion disease," and "consumptive congestion disease." Using this theory to guide clinical syndrome differentiation and treatment and modifying the dosage and usage can play an important role in TCM preventive treatment of cancers, early, middle, and late treatment, and clinical prevention of other chronic diseases.

Patient characteristics predicting prolonged length of hospital stay following robotic-assisted radical prostatectomy

Objective:

The objective of this study is to determine the preoperative patient characteristics predicting prolonged length of hospital stay (pLOS) following robotic-assisted radical prostatectomy (RARP).

Methods:

The National Surgical Quality Improvement Program (NSQIP) database was used to select patients who underwent RARP without other concomitant surgeries between 2008 and 2016. Patients’ demographics, comorbidities, and laboratory markers were collected to evaluate their role in predicting pLOS. The pLOS was defined as length of stay (LOS) >2 days. A multinomial logistic regression was constructed adjusting for postoperative surgical complications to assess for the predictors of pLOS.

Results:

We obtained data for 31,253 patients of which 20,774 (66.5%) patients stayed ⩽1 day, 6993 (22.4%) patients stayed for 2 days, and 3486 (11.2%) patients stayed for >2 days. Demographic variables – including body mass index (BMI) <18.5: odds ratio (OR) = 2.8, 95% confidence interval (CI) = [1.7–4.8]; smoking: OR = 1.2, 95% CI = [1.1–1.4]; and dependent functional status: OR = 3.1, 95% CI = [1.6–6.0] – were predictors of pLOS. Comorbidities – such as heart failure: OR = 4.6, 95% CI = [2.0–10.8]; being dialysis dependent: OR = 2.7, 95% CI = [1.4–5.0]; and predisposition to bleeding: OR = 2.0, 95% CI =  [1.5–2.7] – were the strongest predictors of extended hospitalization. In addition, pLOS was more likely to be associated with postoperative bleeding, renal, or pulmonary complications.

Conclusion:

Preoperative patient characteristics and comorbidities can predict pLOS. These findings can be used preoperatively for risk assessment and patient counseling.

The role of body mass index on quality indicators following minimally-invasive radical prostatectomy

Purpose

We sought to determine the role of body mass index (BMI) on quality indicators, such as length of stay and readmission. The National Surgical Quality Improvement Program (NSQIP) database was queried to examine the effect of obesity, defined as BMI >30, on outcomes after Minimally Invasive Radical Retropubic Prostatectomy (MI-RRP).

Materials and Methods

Utilizing the NSQIP database, patient records were identified using the Current Procedural Terminology (CPT) code 55866 (laparoscopy, surgical prostatectomy, radical retropubic) during a 10-year period (2007–2017). Obesity was classified according to the CDC classification. Chi-square tests were utilized to evaluate BMI distribution by surgery year. Logistic regression was used to evaluate the relationship of BMI with length of stay (LOS) and hospital readmission within 30 days, after controlling for preoperative variables.

Results

Records of 49,238 patients who have undergone MI-RRP during 2007–2017 were evaluated. Mean yearly BMI rose from 28.5 to 29.2, while the percentage of surgical patients with BMI >30 rose by 5% (33% to 38%; p<0.0001) over the study period. Obese patients demonstrated higher morbidity, prolonged LOS, and increased readmission rates after MI-RRP. Obesity severity correlated negatively with quality indicators in a graded fashion.

Conclusions

Obesity rates in patients undergoing MI-RRP increased from 2007–2017. Obese patients are at increased risk of morbidity, prolonged LOS, and readmission within 30 days, following MI-RRP. These patients should not be excluded from MI-RRP; rather, physicians should discuss these increased risks with their patients. Proper weight loss strategies should be instituted preoperatively to mitigate these risks.
