    Days alive and out of hospital after laparoscopic cholecystectomy

    by Harry Alexander, Matthew Moore, Jacqueline Hannam, Garth Poole, Adam Bartlett, Alan Merry

    Background: Days alive and out of hospital (DAOH) is a metric that incorporates several outcomes into a single, standardized measure. This study aimed to explore the utility of DAOH in assessing the outcomes of a retrospective cohort of patients undergoing laparoscopic cholecystectomy (LC).Methods: Patients undergoing LC at Auckland City Hospital between 1 January 2010 and 31 August 2015 were included. DAOH values were calculated for the 90 days from the date of surgery (DAOH90) and described using median and interquartile ranges (IQR). DAOH90 distributions were compared using a two‐tailed (non‐parametric) Wilcoxon‐Mann–Whitney test.Results: 1652 patients undergoing LC were studied. Patients experiencing complications (n = 70, 4.2%) had fewer DAOH90 (median 83, IQR 79, 86) than patients who underwent uncomplicated LC (median 88, IQR 86, 88), P < 0.001. Patients who were converted to open cholecystectomy (n = 70, 4.2%) also had fewer DAOH90 (median 82.5, IQR 79, 84) than patients who underwent uncomplicated LC, P < 0.001. Post‐operative complications and conversion had a statistically significant effect on DAOH90 at each of the tested quantiles, except for conversion at the 0.1 quantile.Conclusion: DAOH90 is readily calculable from existing New Zealand administrative data sources and is sensitive to the occurrence of complications after LC.

  • Selective internal radiation therapy for hepatic metastases of uveal melanoma: a systematic review

    by Harry Alexander, Daniel Wen, Michael Chu, Catherine Han, Peter Hadden, Robert Thomas, Adam Bartlett

    Objective: Uveal melanoma (UM) commonly metastasizes to the liver. Treatment usually consists of liver-directed therapies, such as selective internal radiation therapy (SIRT). This review aimed to assess the effectiveness and safety of SIRT for hepatic metastases from UM. Methods: The study protocol is available at OSF (https://osf.io/vhyct/). EMBASE and MEDLINE were searched until July 2020, using terms related to SIRT and hepatic metastases from UM. Studies reporting outcomes of SIRT in patients with UM and at least one hepatic metastasis were included. Data on overall survival (OS), hepatic progression free survival (hPFS) or tumor response were collected. The Newcastle-Ottawa Scale (NOS) was used to assess risk of bias. Results: 11 studies were included, reporting outcomes for 268 patients with hepatic metastases from UM. Most studies (n = 9, 81.8%) were retrospective. Disease control was achieved in 170 patients (67.5%) and the median OS from time of SIRT was 12.3 months. Median hPFS was 5.4 months. Low-grade side-effects were common but serious complications were infrequent. There were two treatment-related deaths. The median NOS score was 6 (moderate risk of bias). Conclusion: SIRT appears to be a safe and effective treatment for patients with unresectable hepatic metastases from UM. The certainty of our results is unclear due to predominantly retrospective data with moderate risk of bias. Further prospective studies are required to explore the role of SIRT in UM. Advances in knowledge: SIRT appears to be a safe treatment for patients with unresectable hepatic metastases from UM. Further prospective work is required.

  • Checklists for image-guided interventions: a systematic review

    by Harry C Alexander, Scott JP McLaughlin, Robert H Thomas, Alan F Merry

    Objectives: Safety checklists have improved safety in patients undergoing surgery. Checklists have been designed specifically for use in image-guided interventions. This systematic review aimed to identify checklists designed for use in radiological interventions and to evaluate their efficacy for improving patient safety. Secondary aims were to evaluate attitudes toward checklists and barriers to their use. Methods: OVID, MEDLINE, CENTRAL and CINAHL were searched using terms for “interventional radiology” and “checklist”. Studies were included if they described pre-procedural checklist use in vascular/body interventional radiology (IR), paediatric IR or interventional neuro-radiology (INR). Data on checklist design, implementation and outcomes were extracted. Results: Sixteen studies were included. Most studies (n = 14, 87.5%) focused on body IR. Two studies (12.5%) measured perioperative outcome after checklist implementation, but both had important limitations. Checklist use varied between 54 and 100% and completion of items on the checklists varied between 28 and 100%. Several barriers to checklist use were identified, including a lack of leadership and education and cultural challenges unique to radiology. Conclusions: We found few reports of the use of checklists in image-guided interventions. Approaches to checklist implementation varied, and several barriers to their use were identified. Evaluation has been limited. There seems to be considerable potential to improve the effective use of checklists in radiological procedures. Advances in knowledge: There are few reports of the use of checklists in radiological interventions, those identified reported significant barriers to the effective use of checklists.


  • Measurement of patient-reported outcomes after laparoscopic cholecystectomy: a systematic review

    by Harry C. Alexander, Cindy H. Nguyen, Matthew R. Moore, Adam S. Bartlett, Jacqueline A. Hannam, Garth H. Poole, Alan F. Merry

    Patient-reported outcome (PRO) measures (PROMs) are increasingly used as endpoints in surgical trials. PROs need to be consistently measured and reported to accurately evaluate surgical care. Laparoscopic cholecystectomy (LC) is a commonly performed procedure which may be evaluated by PROs. We aimed to evaluate the frequency and consistency of PRO measurement and reporting after LC.
