Cystectomy for bladder cancer in elderly patients is not associated with increased 30- and 90-day mortality or readmission, length of stay, and cost: propensity score matching using a population database

The association between frailty, hypogonadism, and postoperative outcomes among men undergoing radical cystectomy

INTRODUCTION

Hypogonadism is associated with frailty, lower health-related quality of life, decreased muscle mass, and premature mortality, which may predispose patients to poor postoperative outcomes. We aimed to determine the prevalence of hypogonadism in men undergoing radical cystectomy (RC) and whether hypogonadism and frailty are associated with adverse postoperative outcomes.

MATERIALS AND METHODS

The IBM MarketScan database was used to identify men who underwent RC between 2012 and 2021. Frailty was determined using published Hospital Frailty Risk Score ranges. Patients were considered to have hypogonadism if diagnosed within 5 years prior to RC. Length of stay (LOS), complications, emergency department (ED) visits and inpatient readmissions were compared. Sub-group analysis of men with hypogonadism was performed to determine the effect of testosterone replacement therapy (TRT) on clinical outcomes.

RESULTS

Among 3,727 men who underwent RC, 226 (6.1%) had a diagnosis of hypogonadism. Overall, 565 (15.2%) men were low-risk frailty, 2,214 (59.4%) intermediate-risk frailty, and 948 (25.4%) were high-risk frailty, and men with hypogonadism were significantly more frail compared to men without hypogonadism (P = 0.027). There was no significant difference in LOS, complications, or rate of ED visits and inpatient readmissions between cohorts (P > 0.05). However, high-risk frailty was associated with an increased risk of 90-day ED visit (HR 1.19, 95%CI 1.00-1.41, P = 0.049) and 90-day readmission (HR 1.60, 95%CI 1.29-1.97, P < 0.001) after RC. Among men with hypogonadism, 58 (25.7%) were on TRT. There was no significant difference in frailty, LOS, complications, or 90-day ED visits or 90-day inpatient readmissions between patient with hypogonadism prescribed TRT and those without TRT.

CONCLUSIONS

These findings suggest that hypogonadism and preoperative frailty may be important to evaluate prior to undergoing RC.

Outcomes of hospital-acquired pressure injuries and present-on-admission pressure injuries: A propensity score matching analysis

BACKGROUND

Pressure injuries (PIs) continue to present significant challenges. In recent years, the number of patients with present-on-admission pressure injury (POA-PI) has increased, but researchers have devoted little attention to it, and little is known about its clinical outcome.

AIMS

To compare the clinical outcomes of POA-PI and hospital-acquired pressure injury (HAPI) patients.

METHODS

In this study, hospitalized patients with pressure injuries were divided into two groups based on whether they acquired the injury in the hospital or already present at the time of their admission. The disease prognosis, duration of stay, and healthcare costs of patients with HAPI and POA-PI were evaluated using propensity score matching analysis (PSM), t-tests, and Mann-Whitney U tests.

RESULTS

The information on 1871 patients was retrieved from the electronic case system retroactively. A total of 305 pairs of patients were effectively matched between the two groups using propensity score matching (HAPI group = 305, POA-PI group = 305). There was no statistically significant difference at characteristics between the two groups (P > 0.05). The percentage of POA-PI group patients who were discharged from the hospital was greater than that of the HAPI group (P < 0.05). Conversely, the percentage of POA-PI group patients who died, ceased receiving treatment, or transferred to the hospital was lower than that of the HAPI group. Patients in the POA-PI group had shorter hospital stays than those in the HAPI group (P < 0.05). Patients in the POA-PI group had lower healthcare costs than those in the HAPI group (P < 0.05).

CONCLUSIONS

Patients with POA-PI have superior clinical outcomes than patients with HAPI, but make up the overwhelming majority of hospitalized patients. It is imperative that future research focuses on the reduction of POA-PI and HAPI incidence and the identification of therapies that will enhance patient prevention for these conditions.

Diagnostic value of the combination of DAPK methylation in urinary sediment and B ultrasound for recurrent urinary bladder cancer

BACKGROUND

Urinary bladder cancer (UBC) is the most common malignancy affecting the urinary system. This study aimed to investigate the diagnostic value of combining DAPK methylation in urinary sediment and B ultrasound in the detection of recurrent UBC.

METHODS

A total of 1021 cases with primary UBC who underwent electrocision of bladder tumor through urethra were included in this study and followed up. Various parameters including B ultrasound, DAPK methylation in urinary sediment, examination of exfoliated cells in the urine, and cystoscopy were performed. The data collected was analyzed using the Kappa test, and receiver operating characteristic (ROC) curve was constructed to assess the diagnostic role in recurrent UBC.

RESULTS

Among the 1021 patients, 115 patients experienced recurrence confirmed by cystoscopy and biopsy within two years and were excluded from the study, resulting in an effective sample size of 906 primary UBC cases. The results of cystoscopy showed agreement with B ultrasound (Kappa = 0.785, P < 0.05), as well as with DAPK methylation in urinary sediment, and the combination of B ultrasound and DAPK methylation (Kappa = 0.517, P < 0.05, Kappa = 0.593, P < 0.05). The combination of B ultrasound with DAPK methylation yielded an area under the curve of 0.922, with a sensitivity of 92.86%, specificity of 91.63%, and a negative predictive value of 99.4%, suggesting that a negative result indicates a low risk of recurrence.

CONCLUSION

The combination of DAPK methylation in urinary sediment with B ultrasound demonstrates high diagnostic performance for recurrent UBC.

Postoperative Mortality Rate after Radical Cystectomy: A Systematic Review of Epidemiologic Series

INTRODUCTION

Mortality after radical cystectomy (RC) varies widely in the literature. In cohort studies, mortality rates can vary from as low as 0.5% in large-volume academic centers (2) to as high as 25% in developing countries series. This study aims to perform a systematic review of population-based studies reporting mortality after RC.

METHODS

A Systematic search was performed in Medline (PubMed®), Embase, and Cochrane for epidemiologic studies reporting mortality after RC. Institutional cohorts and those reporting mortality for specific groups within populations were excluded. Case series and non-epidemiologic series were also excluded. The aim of this review is to evaluate in-hospital mortality (IHM), 30-day mortality (30M), and 90-day mortality (90M).

RESULTS

Systematic search resulted in 42 papers comprising 449,661 patients who underwent RC from 1984 to 2017. Mean age was 66.1. Overall IHM, 30M, and 90M were 2.6%, 2.7%, and 4.9%, respectively, with 90M being 2.6 times higher than IHM on average. Lowest IHM was found in Canada and Australia (0.2% and 0.6%, respectively), while the highest IHM was 7.8% (Brazil). Canada and Spain showed the highest 90M (6.5%). 159,584 urinary diversions were analyzed, being mostly ileal conduits (76.8%).

CONCLUSIONS

The majority of the studies available are from major developed economies with paucity of data in the developing world. 90M after RC tends to be at least twice as high as IHM. The knowledge of such epidemiologic data is vital to guide public policies, such as centralization, in order to reduce mortality.

StOP? II trial: cluster randomized clinical trial to test the implementation of a toolbox for structured communication in the operating room-study protocol

Background

Surgical care, which is performed by intensely interacting multidisciplinary teams of surgeons, anesthetists, and nurses, remains associated with significant morbidity and mortality. Intraoperative communication has been shown to be associated with surgical outcomes, but tools ensuring efficient intraoperative communication are lacking. In a previous study, we developed the StOP?-protocol that fosters structured intraoperative communication. Before the critical phases of the operation, the responsible surgeon initiates and leads one or several StOP?s. During a StOP?, the surgeon informs about the progress of the operation (status), next steps and proximal goals (objectives), and possible problems (problems) and encourages all team members to voice their observations and ask questions (?). In a before-after study performed mainly in visceral surgery, we found effects of the StOP?-protocol on mortality, length of hospital stay, and reoperation. We intend to assess the impact of the StOP?-protocol in a cluster randomized trial, in a wider variety of surgical specialties (i.e., general, visceral, thoracic, vascular surgery, surgical urology, and gynecology). The primary hypothesis is that the consistent use of the StOP?-protocol by the main surgeon reduces patient mortality within 30 days after the operation. The secondary hypothesis is that the consistent use of the StOP?-protocol by the main surgeon reduces unplanned reoperations, length of hospital stay, and unplanned hospital readmissions.

Methods

This study is designed as a multicenter, cluster-randomized parallel-group trial. Board-certified surgeons of participating clinical departments will be randomized 1:1 to the StOP? intervention group or to the standard of care (control) group. The intervention group will undergo a training to use the StOP?-protocol and receive regular feedback on their compliance with the protocol. The surgeons in the control group will communicate as usual during their operations. The unit of observation will be operations performed by cluster surgeons. Consecutive patients will be enrolled over 4 months per cluster. A total of 400 surgeons will be recruited, and we expect to collect patient outcome data for 14,000 surgical procedures.

Discussion

The StOP?-protocol was designed as a tool to structure communication during surgical procedures. Testing its effects on patient outcomes will contribute to implementing evidenced-based interventions to reduce surgical complications.

Geriatric Assessments Can Predict Functional Outcome and Mortality after Urological Tumor Surgery

INTRODUCTION

Older patients undergoing major urological tumor surgery are at severe risk of functional deterioration, complications, and mortality. We prospectively evaluated geriatric assessment tools and developed a novel easy-to-use assessment tool for clinical use.

METHODS

In 159 patients, geriatric assessment tools were used prior to cystectomy, prostatectomy, and renal tumor surgery, and their peri- and postoperative courses were recorded. Using all the tests, a short and easy-to-use assessment tool was developed, and nomograms were generated to predict functional outcomes and mortality.

RESULTS

Of all the patients, 13.8% underwent radical cystectomy, 37.7% underwent radical prostatectomy, and 48.4% underwent tumor surgery of the kidney at the age of 70 years or older. The average age was 75.6 years. Incomplete functional recovery at day 30 and day 180 was observed in 37.7% and 36.1% of the patients, respectively, and incomplete functional recovery was associated with impaired mobility, previous care dependency, frailty, comorbidities, and a high ASA score. The only predictor for high-grade complications was comorbidities, whereas mortality was associated with the geriatric screening tool scores, impaired mobility, preoperative care dependency, and comorbidities. The Erlangen Index (EI), a combination of the selected assessment tools, showed a good prediction of early (p = 0.002) and medium-term (p = 0.002) functional outcomes and mortality (p = 0.001).

CONCLUSION

Our prospective evaluation confirms the high risk of incomplete functional recovery, high-grade complications, and mortality in older patients undergoing major urological tumor surgery. The EI is an easy-to-use preoperative assessment tool and therefore should be used in preoperative patient counseling.

Short-term morbidity and mortality following radical cystectomy: a systematic review

OBJECTIVE

To study short-term (<90 days) morbidity and mortality following radical cystectomy (RC) for bladder cancer and identify modifiable risk factors associated with these.

DESIGN

Systematic review.

METHODS

The systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed and EMBASE were searched for relevant papers on 11 June 2019 and rerun on 27 May 2020. Studies reporting complications, reoperations, length of stay and mortality within 90 days were included. Studies were reviewed according to criteria from the Oxford Centre for Evidence-Based Medicine and the quality of evidence was assessed using the Newcastle-Ottawa Scale.

RESULTS

The search retrieved 1957 articles. Sixty-six articles were included. The quality of evidence was poor to good. Most studies were retrospective, and no randomised clinical trials were identified. Of included studies a median of 6 Martin criteria for reporting complications after surgery were fulfilled. The Clavien-Dindo classification for grading complications was most frequently used. The weighted overall complication rate after RC was 34.9% (range 28.8-68.8) for in-house complications, 39.0% (range 27.3-80.0) for 30-day complications and 58.5% (range 36.1-80.5) for 90-day complications. The most common types of complications reported were gastrointestinal (29.0%) and infectious (26.4%). The weighted mortality rate was 2.4% (range 0.9-4.7) for in-house mortality, 2.1% (0.0-3.7) for 30-day mortality and 4.7% (range 0.0-7.0) for 90-day mortality. Age and comorbidity were identified as the best predictors for complications following RC.

CONCLUSION

Short-term morbidity and mortality are high following RC. Reporting of complications is heterogeneous and the quality of evidence is generally low. There is a continuous need for randomised studies to address any intervention that can reduce morbidity and mortality following RC.

The impact of frailty on the economic evaluation of geriatric surgery: hospital costs and opportunity costs based on meta-analysis

Objectives: We used a systematic review and meta-analysis to analyze the difference in costs between surgery for frail and non-frail elderly patients. The opportunity cost of frailty in geriatric surgery is estimated using the results.Methodology: Two literature reviews were carried out between 2000 and 2019: (1) studies comparing total hospital costs of frail and non-frail surgical patients; (2) studies evaluating the length of hospital stay and cost for surgical geriatric patients. We performed a meta-analysis of the items selected in the first review. We subsequently calculated the opportunity cost of frail patients, based on the design of a cost/time variable.Results: Twelve articles in the first review were selected (272,717 non-frail and 16,461 frail). Fourteen articles were selected from the second review. Frail patients had higher hospital costs than non-frail patients (22,282.541 € and 16,388.844, p < .001) and a longer hospital stay (10.16 days and 8.4 (p < .001)). The estimated opportunity cost in frail patients is 1,019.56 € (cost/time unit factor of 579.30 €/day).Conclusions: Frail surgical geriatric patients generate a higher total hospital cost, and an opportunity cost arising from not operating in the best possible state of health. Preoperatively treating the frailty of elderly patients will improve the use of health resources.

[Optimizing the management of bladder cancer in older patients]

AIM

To define and present potential improvements for the management of bladder cancer in older patients.

METHOD

Bibliographical search was performed from the Medline bibliographic database (NLM Pubmed tool) and Embase focused on: bladder cancer, treatment, BCG, chemotherapy, cystectomy, and elderly.

RESULTS

The oncological principles of medico-surgical management of bladder cancer do not differ according to age. On the other hand, the patient comorbidities have been likely to alter the tolerance of these treatments. At the NMIBC stages, no adaptation of the standard treatment has demonstrated any interest. At the MIBC stages, the prognosis was improved by geriatric multidisciplinary perioperative management.

CONCLUSION

The indications and principles of surgical treatments must be identical regardless of the patient age. At the NMIBC stages, adjuvant therapy, including BCG therapy, should not be questioned because of the age of the patient. On the other hand, at the localized MIBC stages, neoadjuvant and adjuvant chemotherapy should not be considered as a standard and their indications assessed individually after geriatric assessment.
