Surgical quality in organ procurement during day and night: an analysis of quality forms

Ten Years of Quality Monitoring of Abdominal Organ Procurement in the Netherlands and Its Impact on Transplant Outcome

In this study, 10 years of procurement quality monitoring data were analyzed to identify potential risk factors associated with procurement-related injury and their association with long-term graft survival. All deceased kidney, liver, and pancreas donors from 2012 to 2022 and their corresponding recipients in the Netherlands were retrospectively included. The incidence of procurement-related injuries and potential risk factors were analyzed. Of all abdominal organs procured, 23% exhibited procurement-related injuries, with a discard rate of 4.0%. In kidneys and livers, 23% of the grafts had procurement-related injury, with 2.5% and 4% of organs with procurement-related injury being discarded, respectively. In pancreas procurement, this was 27%, with a discard rate of 24%. Male donor gender and donor BMI >25 were significant risk factors for procurement-related injury in all three abdominal organs, whereas aberrant vascularization was significant only for the kidney and liver. In the multivariable Cox regression analyses, procurement-related injury was not a significant predictor for graft failure (kidney; HR 0.99, 95% CI 0.75-1.33, p = 0.99, liver; HR 0.92, 95% CI 0.66-1.28, p = 0.61, pancreas: HR 1.16; 95% CI 0.16-8.68, p = 0.88). The findings of this study suggest that transplant surgeons exhibited good decision-making skills in determining the acceptability and repairability of procurement-related injuries.

Are Prospective Criteria or Objective Clinical Measures Utilized in Return to Play (RTP) Decision Making After Ankle Surgery? A Scoping Review

Background

Manuscripts discussing return to play (RTP) following ankle surgery are common. However, the definition for RTP and the method by which it is determined remains unclear. The purpose of this scoping review was to clarify how RTP is defined following ankle surgery in physically active patients, to identify key factors informing RTP decision making (such as objective clinical measures), and make recommendations for future research.

Methods

A scoping literature review was performed in April 2021 using PubMed, EMBASE, and Nursing and Allied Health databases. Thirty studies met inclusion criteria: original research following ankle surgery reporting at least 1 objective clinical test and documentation of RTP. Data were extracted for study methods and outcomes (RTP definition, RTP outcomes, and objective clinical tests).

Results

The scoping review found studies on 5 ankle pathologies: Achilles tendon rupture, chronic lateral ankle instability, anterior ankle impingement, peroneal tendon dislocation, and ankle fracture. RTP criteria were not provided in the majority of studies (18/30 studies). In the studies that provided them, the RTP criteria were primarily based on time postsurgery (8/12) rather than validated criteria. Objective clinical outcome measures and patient-reported outcome measures (PROMs) were documented for each surgery when available. Both clinical outcomes and PROMs were typically measured >1 year postsurgery.

Conclusion

In physically active patients who have had ankle surgery, RTP remains largely undefined and is not consistently based on prospective objective criteria nor PROMS. We recommend standardization of RTP terminology, adoption of prospective criteria for both clinical measures and PROMs to guide RTP decision making, and enhanced reporting of patient data at the time of RTP to develop normative values and determine when the decision to RTP is not safe.

Incidence and risk factors for surgical site infection following volar locking plating (VLP) of unstable distal radius fracture (DRF)

PURPOSE

Volar locking plating (VLP) is the mainstay of treatment for distal radius fracture (DRF) but may be compromised by postoperative surgical site infection (SSI). This study aimed to identify the incidence and the risk factors for SSI following VLP of DRF.

METHODS

This retrospective study identified consecutive patients who underwent VLP for closed unstable DRFs in our institution between January 2015 and June 2021. Postoperative SSI was identified by inquiring the medical records, the follow-up records or the readmission medical records for treatment of SSI. The potential factors for SSI were extracted from the medical records. Univariate and multivariate logistic regression analyses were performed to identify the independent factors.

RESULTS

There were 930 patients included, and 34 had an SSI, representing an incidence of 3.7% (95% CI 2.4-4.9%). Patients with an SSI had threefold extended hospitalization stay (44.1 ± 38.2 versus 14.4 ± 12.5 days) as did those without. In univariate analysis, 18 variables were tested to be statistically different between SSI and non-SSI group. In multivariate analysis, 6 factors were identified as independently associated with SSI, including sex (male vs. female, OR 3.5, p = 0.014), ASA (III and IV vs. I, OR 3.2, p = 0.031), smoking (yes vs. no, OR 2.4, p = 0.015), bone grafting (OR 4.0, p = 0.007), surgeon volume (low vs. high, OR 2.7, p 0.011) and operation at night-time (vs. day-time, OR 7.8, p < 0.001).

CONCLUSION

The postoperative SSI of VLP of DRF was not uncommon, and the factors identified in this study, especially those modifiable, would help identify individual SSI risk, target clinical surveillance and inform patient counseling.

Centralized Organ Recovery and Reconditioning Centers

An increased focus on improving efficiency and decreasing costs has resulted in alternative models of donor management and organ recovery. The specialized donor care facility model provides highly efficient and cost-effective donor care at a free-standing facility, resulting in improved organ yield, shorter ischemic times, decreased travel, and fewer nighttime operations. Ex vivo lung perfusion (EVLP) improves utilization of extended criteria donor lungs, and centralized EVLP facilities have the potential to increase transplant volumes for smaller transplant programs in specified geographic regions. These alternative models are increasingly being used in the United States to improve waitlist mortality and combat the ongoing donor organ shortage.

Lumbar decompression surgery for cauda equina syndrome - comparison of complication rates between daytime and overnight operating

PURPOSE

To investigate the incidence of complications from lumbar decompression ± discectomy surgery for cauda equina syndrome (CES), assessing whether time of day is associated with a change in the incidence of complications.

METHODS

Electronic clinical and operative notes for all lumbar decompression operations undertaken at our institution for CES over a 2-year time period were retrospectively reviewed. "Overnight" surgery was defined as any surgery occurring between 18:00 and 08:00 on any day. Clinicopathological characteristics, surgical technique, and peri/post-operative complications were recorded. Multivariable logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals.

RESULTS

A total of 81 lumbar decompression operations were performed in the 2-year period and analysed. A total of 29 (36%) operations occurred overnight. Complete CES (CESR) was seen in 13 cases (16%) in total, 7 of whom underwent surgery during the day. Exactly 27 complications occurred in 24 (30%) patients. The most frequently occurring complication was a dural tear (n = 21, 26%), followed by post-operative haematoma, infection, and residual disc. Complication rates in the CESR cohort (54%) were significantly greater than in the CES incomplete (CESI) cohort (25%) (p = 0.04). On multivariable analysis, overnight surgery was independently associated with a significantly increased complication rate (OR 2.83, CI 1.02-7.89).

CONCLUSIONS

Lumbar decompressions performed overnight for CES were more than twice as likely to suffer a complication, in comparison to those performed within daytime hours. Our study suggests that out-of-hours operating, particularly at night, must be clinically justified and should not be influenced by day-time operating capacity.

Initiation of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) for cardiogenic shock during out of hours versus working hours is not associated with increased mortality

BACKGROUND

Initiation of veno-arterial (VA) Extracorporeal Membrane Oxygenator (ECMO) is associated with severe complications. It is unknown whether these adverse consequences occur more often after initiations during out of hours service compared to working hours.

METHODS

All patients receiving VA-ECMO for cardiogenic shock between 2009 and 2020 were categorized into a working hours group (between 8 am and 5 pm on weekdays) and an out of hours service group (between 5 pm and 8 am, or between Friday 5 pm and Monday 8 am). Primary outcome was all-cause mortality at 30 days. Secondary outcomes included vascular complications (including limb ischemia and/or bleeding), bloodstream infections and length of ICU stay. Propensity scores were used to adjust for potential confounding effects.

RESULTS

Among 250 patients (median (IQR) age 56 (42-64) years) receiving VA-ECMO (median duration 3.5 (1.0-9.0) days), 160 (64%) runs were initiated between 5 pm and 8 am whereas the remainder (36%) started during working hours. Characteristic did not differ between the working hours- and out of hours-group. By day 30, 37 (41.1%), and 68 (42.5%) patients in either group had died, respectively (p = 0.831). VA-ECMO support duration and length of stay on the ICU did not differ significantly in both crude and adjusted analyses. More complications occurred during out of hours service (p = 0.039).

CONCLUSIONS

Out of hours- versus working hours-initiation of VA-ECMO for cardiogenic shock was not associated with higher mortality, longer VA-ECMO support duration, or longer length of stay on the intensive care. Vascular complications were more common in the out of hours group.

Nighttime Kidney Transplant From Donor With Controlled Cardiac Death: Greater Functionality at the Cost of More Complications?

BACKGROUND

Kidney transplantation surgery from controlled cardiac death donor (Maastricht III) is frequently performed at night, without taking into account the accumulated fatigue that the surgical team may experience. The objective of the study is to assess whether surgical complications and the functionality of the graft in the short and long term are affected by the time of day in which kidney transplantation from controlled cardiac death donors is performed.

METHODS

A retrospective observational study was carried out. Patient were classified according to the start of surgery, daytime hours (8:00 AM to 7:59 PM), and nighttime hours (8:00 PM to 7:59 AM). Baseline and intraoperative parameters, postoperative complications, and parameters related to graft functionality were analyzed.

RESULTS

A total of 77 patients were included: 37 patients had kidney transplantations performed during the daytime (48.05%), and 40 patients had kidney transplantations performed at nighttime (51.95%). No statistically significant differences were found between the baseline characteristics of both groups except for sex (55.0% men in daytime vs 78.4% men in nighttime, P = .03) and time on pretransplant dialysis (33.1 months in daytime vs 13.8 months in nighttime, P = .008). The incidence of surgical complications and the functionality of the graft was similar in both groups; however, the surgical time was shorter in night transplants (163.2 minutes in daytime vs 136.5 minutes at nighttime, P = .0006) CONCLUSION: The performance of kidney transplants at night is not associated, either in the short or long term, with an increase in surgical complications or conditions leading to the deterioration in the functionality of the graft.

Specialized Donor Care Facility Model and Advances in Management of Thoracic Organ Donors

BACKGROUND

Donor hearts and lungs are more susceptible to the inflammatory physiologic changes that occur after brain death. Prior investigations have shown that protocolized management of potential organ donors can rehabilitate donor organs that are initially deemed unacceptable. In this review we discuss advances in donor management models with particular attention to the specialized donor care facility model. In addition we review specific strategies to optimize donor thoracic organs and improve organ yield in thoracic transplantation.

METHODS

We performed a literature review by searching the PubMed database for medical subject heading terms associated with organ donor management models. We also communicated with our local organ procurement organization to gather published and unpublished information first-hand.

RESULTS

The specialized donor care facility model has been shown to improve the efficiency of organ donor management and procurement while reducing costs and minimizing travel and its associated risks. Lung protective ventilation, recruitment of atelectatic lung, and hormone therapy (eg, glucocorticoids and triiodothyronine/thyroxine) are associated with improved lung utilization rates. Stroke volume-based resuscitation is associated with improved heart utilization rates, whereas studies evaluating hormone therapy (eg, glucocorticoids and triiodothyronine/thyroxine) have shown variable results.

CONCLUSIONS

Lack of high-quality prospective evidence results in conflicting practices across organ procurement organizations, and best practices remain controversial. Future studies should focus on prospective, randomized investigations to evaluate donor management strategies. The specialized donor care facility model fosters a collaborative environment that encourages academic inquiry and is an ideal setting for these investigations.

Donor management using a specialized donor care facility is associated with higher organ utilization from drug overdose donors

Drug overdoses have tripled in the United States over the last two decades. With the increasing demand for donor organs, one potential consequence of the opioid epidemic may be an increase in suitable donor organs. Unfortunately, organs from donors dying of drug overdose have poorer utilization rates than other groups of brain-dead donors, largely due to physician and recipient concerns about viral disease transmission. During the study period of 2011 to 2016, drug overdose donors (DODs) account for an increasingly greater proportion of the national donor pool. We show that a novel model of donor care, known as specialized donor care facility (SDCF), is associated with an increase in organ utilization from DODs compared to the conventional model of hospital-based donor care. This is likely related to the close relationship of the SDCF with the transplant centers, leading to improved communication and highly efficient donor care.

Impact of Nighttime Lung Transplantation on Outcomes and Costs

BACKGROUND

Previous studies in the field of organ transplantation have shown a possible association between nighttime surgery and adverse outcomes. We aim to determine the impact of nighttime lung transplantation on postoperative outcomes, long-term survival, and overall cost.

METHODS

We performed a single-center retrospective cohort analysis of adult lung transplant recipients who underwent transplantation between January 2006 and December 2017. Data were extracted from our institutional Lung Transplant Registry and Mid-America Transplant services database. Patients were classified into 2 strata, daytime (5 AM to 6 PM) and nighttime (6 PM to 5 AM), based on time of incision. Major postoperative adverse events, 5-year overall survival, and 5-year bronchiolitis obliterans syndrome-free survival were examined after propensity score matching. Additionally we compared overall cost of transplantation between nighttime and daytime groups.

RESULTS

Of the 740 patients included in this study, 549 (74.2%) underwent daytime transplantation and 191 (25.8%) underwent nighttime transplantation (NT). Propensity score matching yielded 187 matched pairs. NT was associated with a higher risk of having any major postoperative adverse event (adjusted odds ratio, 1.731; 95% confidence interval, 1.093-2.741; P = .019), decreased 5-year overall survival (adjusted hazard ratio, 1.798; 95% confidence interval, 1.079-2.995; P = .024), and decreased 5-year bronchiolitis obliterans syndrome-free survival (adjusted hazard ratio, 1.556; 95% confidence interval, 1.098-2.205; P = .013) in doubly robust multivariable analyses after propensity score matching. Overall cost for NT and daytime transplantation was similar.

CONCLUSIONS

NT was associated with a higher risk of major postoperative adverse events, decreased 5-year overall survival, and decreased 5-year bronchiolitis obliterans syndrome-free survival. Our findings suggest potential benefits of delaying NT to daytime transplantation.

The Impact of Physicians' Working Hours on Inappropriate Use of Outpatient Medicine in a Tertiary Hospital in China

BACKGROUND

Inappropriate prescribing is an important health system problem in China. Several studies have identified critical factors influencing prescription quality, but the impact of physicians' working hours remains unknown. In China, tertiary hospitals face ever-increasing outpatient volumes. Physicians are asked to work long hours and the impact of shift duration on prescription quality is unknown.

OBJECTIVE

We aimed to investigate the association between consecutive working hours and the quality of physicians' prescriptions in a Chinese tertiary hospital.

METHODS

We obtained all outpatient electronic health records from the hospital information system (HIS) of a tertiary hospital in Beijing, China from 1 July to 30 November 2015. Prescriptions made during two periods were analyzed: a morning shift from 7:30 to 12:30, and an afternoon shift from 13:30 to 18:30. The time when a physician issued the first prescription was considered the beginning of the work shift and prescriptions within the next 4 consecutive hours were included. Potentially inappropriate prescriptions were based on the Rational Drug Use (RDU) system that was developed and validated for this study. We used multivariable logistic regression to examine the impact of shift duration and other clinical and physician factors on potentially inappropriate prescribing.

RESULTS

Of the total 560,529 prescriptions, 15.3% were classified as inappropriate by the RDU system. Physicians' inappropriate prescribing increased in the last hour in each work shift (odds ratio (OR) for the fourth hour compared to the first = 1.12 (95% CI, 1.09-1.15)). We also found that physicians who worked all day had a higher rate of inappropriate prescribing than those who only worked half a day (OR = 1.05 (95% CI, 1.04-1.07)).

CONCLUSIONS

Longer working hours are a risk factor for inappropriate prescribing. Relevant interventions are urgently needed to establish working hour limits in China to reduce the likelihood of inappropriate prescribing by physicians.

The weekend effect in kidney transplantation outcomes: a French cohort-based study

Numerous studies have reported a weekend effect on outcomes for diseases treated at hospitals. No study has been conducted in France for kidney transplantation. We therefore performed a cohort-based study to evaluate whether outcomes of kidney transplant recipients display a weekend effect. Data were extracted from the French DIVAT cohort. Patients aged 18 years and older, transplanted with a single kidney from deceased donors between 2005 and 2017 were studied. Linear regression, logistic regression, and cause-specific Cox model were used. Among the 6652 studied patients, 4653 patients were transplanted during weekdays (69.9%) versus 1999 during weekends (30.1%). The only statistically significant difference was the percentage of patients with vascular surgical complication(s) at 30 days: 13.3% in the weekend group versus 16.2% in the weekday group 0.79 (95% CI: 0.68; 0.92). We did not observe other significant differences for the other outcomes: patient or graft survival, the risk of acute rejection episodes, the 30-day percentage of urological complications, and the 1-year estimated glomerular filtration rate. Our study highlights a small protective weekend effect with less post-surgery vascular complications compared to weekdays. This paradox might be explained by a different handling of weekend transplantations.

A review of current approaches for evaluating impaired performance in around-the-clock medical professionals

The need for data to study the relationship between fatigued healthcare professionals and performance outcomes is evident, however, it is unclear which methodology is most appropriate to provide these insights. To address this issue, we performed a systematic review of relevant articles by searching the MEDLINE, EMBASE, Cochrane, Web of Science, and CINAHL databases. The literature search identified 2960 unique references, of which 82 were identified eligible. The impact on performance was studied on clinical outcomes, medical simulation, neurocognitive performance, sleep quantification and subjective assessment. In general results on performance are conflicting; impairment, no effect, and improvement were found. This review outlines the various methods currently available for assessing fatigue-impaired performance. The contrasting outcomes can be attributed to three main factors: differences in the operationalisation of fatigue, incomplete control data, and the wide variety in the methods used. We recommend the implementation of a clinically applicable tool that can provide uniform data. Until these data become available, caution should be used when developing regulations that can have implications for physicians, education, manpower planning, and ‒ ultimately ‒ patient care.
