Hospital-level Variation in the Quality of Benign Inpatient Urologic Surgery

Quality Indicators in the Clinical Specialty of Urology: A Systematic Review

CONTEXT

In health care, monitoring of quality indicators (QIs) in general urology remains underdeveloped in comparison to other clinical specialties.

OBJECTIVE

To identify, synthesise, and appraise QIs that monitor in-hospital care for urology patients.

EVIDENCE ACQUISITION

This systematic review included peer-reviewed articles identified via Embase, MEDLINE, Web of Science, CINAHL, Global Health, Google Scholar, and grey literature from 2000 to February 19, 2021. The review was carried out under the Preferred Reporting Items of Systematic Reviews and Meta-Analyses (PRISMA) guidelines and used the Appraisal of Indicators through Research and Evaluation (AIRE) tool for quality assessment.

EVIDENCE SYNTHESIS

A total of 5111 articles and 62 government agencies were screened for QI sets. There were a total of 57 QI sets included for analysis. Most QIs focused on uro-oncology, with prostate, bladder, and testicular cancers the most represented. The most common QIs were surgical QIs in uro-oncology (positive surgical margin, surgical volume), whereas in non-oncology the QIs most frequently reported were for treatment and diagnosis. Out of 61 articles, only four scored a total of ≥50% on the AIRE tool across four domains. Aside from QIs developed in uro-oncology, general urological QIs are underdeveloped and of poor methodological quality and most lack testing for both content validity and reliability.

CONCLUSIONS

There is an urgent need for the development of methodologically robust QIs in the clinical specialty of general urology for patients to enable standardised quality of care monitoring and to improve patient outcomes.

PATIENT SUMMARY

We investigated a range of quality indicators (QIs) that provide health care professionals with feedback on the quality of their care for patients with general urological diseases. We found that aside from urological cancers, there is a lack of QIs for general urology. Hence, there is an urgent need for the development of robust and disease-specific QIs in general urology.

Predictability and Practicality of Image-Based Scoring Systems for Patient Assessment and Outcome Stratification During Percutaneous Nephrolithotomy: a Contemporary Update

Preoperative nomograms offer systematic and quantitative methods to assess patient- and stone-related characteristics and their impact on successful treatment and potential risk of complication. Discrepancies in the correlation of perioperative variables to patient outcomes have led to the individual development, validation, and application of four independent scoring systems for the percutaneous nephrolithotomy: Guy's stone score, S.T.O.N.E. nephrolithometry, Clinical Research Office of the Endourology Society nomogram, and Seoul National University Renal Stone Complexity. The optimal nomogram should have high predictive ability, be practically integrated into clinical use, and be widely applicable to urinary stone disease. Herein, we seek to provide a contemporary evaluation of the advantages, disadvantages, and commonalities of each scoring system. While the current data is insufficient to conclude which scoring system is destined to become the gold standard, it is crucial that a nephrolithometric scoring system be incorporated into common practice to improve surgical planning, patient counseling, and outcome assessment.

The Impact of Increasing Hospital Volume on 90-Day Postoperative Outcomes Following Pancreaticoduodenectomy

BACKGROUND

Performance of pancreaticoduodenectomy (PD) in high-volume centers has been posited to improve postoperative morbidity and mortality, consistent with the volume-outcomes hypothesis. We sought to evaluate the impact of hospital volume on 90-day PD outcomes at hepatopancreatobiliary (HPB) centers within a regionalized system.

METHODS

A retrospective population-based observational cohort study was performed, using administrative records of patients undergoing PD between 2005 and 2013 in Ontario, Canada. Postoperative administrative codes were used to define complications. Patients' 90-day postoperative outcomes were compared between center-volume categories using chi-square tests and multivariable regression. Volume cutoffs were defined using minimal regional standards (20PD/year), with assessment of the impact of further volume increases.

RESULTS

Of 2660 patients, 2563 underwent PD at HPB centers. Of these, 38.9% underwent surgery at higher-volume centers (>40 PD/year), 36.9% at medium-volume centers (20-39 PD/year), and 24.1% at lower-volume centers (10-19 PD/year). Mortality (30- and 90-day) was lowest at higher-volume hospitals (1.5%, 2.7%, respectively) compared to medium-volume (3.9%, 6.3%) and lower-volume hospitals (2.9%, 5.2%) (p < 0.01). Patients treated at higher- and medium-volume centers had lower reoperation rates (10.3%, 10.7% vs. 16.7%, p = 0.0002) and less prolonged length of stay (23.2%, 22.0% vs. 31.6%, p < 0.0001) compared to lower-volume centers.

CONCLUSION

Progressive increases in hospital volume correspond to improved 90-day outcomes following PD.
