Management of donation after brain death (DBD) in the ICU: the potential donor is identified, what's next?

Characterizing proximity and transfers of deceased organ donors to donor care units in the United States

Some United States organ procurement organizations transfer deceased organ donors to donor care units (DCUs) for recovery procedures. We used Organ Procurement and Transplantation Network data, from April 2017 to June 2021, to describe the proximity of adult deceased donors after brain death to DCUs and understand the impact of donor service area (DSA) boundaries on transfer efficiency. Among 19 109 donors (56.1% of the cohort) in 25 DSAs with DCUs, a majority (14 593 [76.4%]) were in hospitals within a 2-hour drive. In areas with DCUs detectable in the study data set, a minority of donors (3582 of 11 532 [31.1%]) were transferred to a DCU; transfer rates varied between DSAs (median, 27.7%, range, 4.0%-96.5%). Median hospital-to-DCU driving times were not meaningfully shorter among transferred donors (50 vs 51 minutes for not transferred, P < .001). When DSA boundaries were ignored, 3241 cohort donors (9.5%) without current DCU access were managed in hospitals within 2 hours of a DCU and thus potentially eligible for transfer. In summary, approximately half of United States deceased donors after brain death are managed in hospitals in DSAs with a DCU. Transfer of donors between DSAs may increase DCU utilization and improve system efficiency.

Assessing Outcomes of Patients Subject to Intensive Care to Facilitate Organ Donation: A Spanish Multicenter Prospective Study

Intensive Care to facilitate Organ Donation (ICOD) consists of the initiation or continuation of intensive care measures in patients with a devastating brain injury (DBI) in whom curative treatment is deemed futile and death by neurological criteria (DNC) is foreseen, to incorporate organ donation into their end-of-life plans. In this study we evaluate the outcomes of patients subject to ICOD and identify radiological and clinical factors associated with progression to DNC. In this first prospective multicenter study we tested by multivariate regression the association of clinical and radiological severity features with progression to DNC. Of the 194 patients, 144 (74.2%) patients fulfilled DNC after a median of 25 h (95% IQR: 17-44) from ICOD onset. Two patients (1%) shifted from ICOD to curative treatment, both were alive at discharge. Factors associated with progression to DNC included: age below 70 years, clinical score consistent with severe brain injury, instability, intracranial hemorrhage, midline shift ≥5 mm and certain types of brain herniation. Overall 151 (77.8%) patients progressed to organ donation. Based on these results, we conclude that ICOD is a beneficial and efficient practice that can contribute to the pool of deceased donors.

The effectiveness of video training in improving intensive care nurses' knowledge about brain death identification

BACKGROUND

Because patients diagnosed with brain death in intensive care units constitute a potential cadaveric donor group for organ transplantation, intensive care units are potential donor sources. Nurses who closely monitor the patient collaborate with medical personnel in the recognition and early diagnosis of brain death. Nurses also have an important role in supporting the patient's family. Therefore, it is very important for nurses to know the diagnostic criteria for brain death.

AIM

The aim of this study was to compare the effectiveness of theoretical education and video-assisted education in equipping intensive care nurses to recognize brain death.

STUDY DESIGN

A randomized, experimental study was conducted between February and May 2020 with a total of 50 intensive care nurses, split into 25 in the video-assisted training group and 25 in the theoretical training group. In study, intensive care nurses were given a theoretical training and video-assisted training on brain death criteria. One group was trained theoretically and the other group used a video showing criteria for brainstem reflexes (pupil assessment, spontaneous breathing, corneal reflex, retching and coughing assessments) and deep tendon reflexes in a simulated patient, supported by animation. The data were collected before, immediately after and 3 months after the training using the Brain Death Criteria Knowledge Test, the Brain Death Case Test, and the Training Effectiveness Evaluation Form. The independent samples t-test, Mann-Whitney U test, Friedman test, Wilcoxon test, and Chi-square test were used for statistical analysis of data.

RESULTS

It was found that the knowledge scores of both groups immediately after training and 3 months after training were higher than before the training (p < .001). However, the post-training knowledge scores of the video-assisted training group were significantly higher than those of the theoretical training group (p = .011).

CONCLUSIONS

To enable intensive care nurses to identify brain death, video-assisted training with a simulated patient is recommended, as is repeating the training at regular intervals.

RELEVANCE TO CLINICAL PRACTICE

The simulated patient video-assisted training method can be used for in-service training to provide intensive care nurses with the ability to identify brain death. The training may be repeated at regular intervals (e.g., every 3 months) to increase nurse recall.

Facilitators and barriers in the donor family interview process from the perspective of hospital staff: a cross-sectional study

Background

Obtaining consent from potential donor families is a challenging step in the donation process and is influenced by various factors.

Methods

In this cross-sectional study, we utilized a questionnaire containing 14 questions about facilitators and barriers in the family interview process. The questionnaire was distributed in March 2023 to intensive care unit (ICU) nurses who had experience with donor family interviews. We collected the opinions of these respondents on hospital performance and drew comparisons between the studied hospitals.

Results

A total of 60 participating ICU nurses provided mean scores for hospital performance in family interviews of 2.60±0.84 for type I hospitals (those providing neurosurgery and trauma care) and 2.035±0.890 for type II hospitals (those without neurosurgery and trauma services; P=0.04). The mean scores for public and private hospitals were 1.86±0.86 and 2.59±0.85, respectively (P=0.008). Based on the findings, the most important facilitators were the availability of organ donation staff and access to a professional team for family discussions. Conversely, poor physician communication skills and limited communication capabilities among medical staff were identified as significant barriers. Implementation of a professional team for family interviews was found to be more critical for type II hospitals. Poor physician communication skills were a significant concern in public hospitals, while families' lack of awareness of patient prognosis emerged as a key barrier in private hospitals.

Conclusions

This study highlights numerous facilitators and barriers that vary across hospitals. Addressing these issues individually and developing tailored plans to enhance hospital performance in interviewing donor families is essential.

Identification of patients at high risk for brain death using an automated digital screening tool: a prospective diagnostic accuracy study

BACKGROUND

An automated digital screening tool (DETECT) has been developed to aid in the early identification of patients who are at risk of developing brain death during critical care.

METHODS

This prospective diagnostic accuracy study included consecutive patients ≥ 18 years admitted to neurocritical care for primary or secondary acute brain injury. The DETECT screening tool searched routinely monitored patient data in the electronic medical records every 12 h for a combination of coma and absence of bilateral pupillary light reflexes. In parallel, daily neurological assessment was performed by expert neurointensivists in all patients blinded to the index test results. The primary target condition was the eventual diagnosis of brain death. Estimates of diagnostic accuracy along with their 95%-confidence intervals were calculated to assess the screening performance of DETECT.

RESULTS

During the 12-month study period, 414 patients underwent neurological assessment, with 8 (1.9%) confirmed cases of brain death. DETECT identified 54 positive patients and sent 281 notifications including 227 repeat notifications. The screening tool had a sensitivity of 100% (95% CI 63.1-100%) in identifying patients who eventually developed brain death, with no false negatives. The mean time from notification to confirmed diagnosis of brain death was 3.6 ± 3.2 days. Specificity was 88.7% (95% CI 85.2-91.6%), with 46 false positives. The overall accuracy of DETECT for confirmed brain death was 88.9% (95% CI 85.5-91.8%).

CONCLUSIONS

Our findings suggest that an automated digital screening tool that utilizes routinely monitored clinical data may aid in the early identification of patients at risk of developing brain death.

Development and validation of a novel score to predict brain death after out-of-hospital cardiac arrest

BACKGROUND AND OBJECTIVES

Brain death (BD) occurs in 9-24% of successfully resuscitated out-of-hospital cardiac arrests (OHCA). To predict BD after OHCA, we developed a novel brain death risk (BDR) score.

METHODS

We identified independent predictors of BD after OHCA in a retrospective, single academic center cohort between 2011 and 2021. The BDR score ranges from 0 to 7 points and includes: non-shockable rhythm (1 point), drug overdose as etiology of arrest (1 point), evidence of grey-white differentiation loss or sulcal effacement on head computed tomography (CT) radiology report within 24 hours of arrest (2 points), Full-Outline-Of-UnResponsiveness (FOUR) score of 0 (2 points), FOUR score 1-5 (1 point), and age <45 years (1 point). We internally validated the BDR score using k-fold cross validation (k = 8) and externally validated the score at an independent academic center. The main outcome was BD.

RESULTS

The development cohort included 362OHCA patients, of whom 18% (N = 58) experienced BD. Internal validation provided an area under the receiving operator characteristic curve (AUC) (95% CI) of 0.931 (0.905-0.957). In the validation cohort, 19.8% (N = 17) experienced BD. The AUC (95% CI) was 0.849 (0.765-0.933). In both cohorts, a BDR score >4 was the optimal cut off (sensitivity 0.903 and 0.882, specificity 0.830 and 0.652, in the development and validation cohorts respectively).

DISCUSSION

The BDR score identifies those at highest risk for BD after OHCA. Our data suggest that a BDR score >4 is the optimal cut off.

Interventions to Improve the Quality in the Organ and Tissue Donation Process

BACKGROUND

Map Interventions is capable of supporting the multidisciplinary team that works in organ and tissue donation to disseminate quality in this process.

METHODS

A scoping review study that was conducted through the steps proposed by the Joanna Briggs Institute.

RESULTS

Fifty-six studies made up the sample. 2018 (no. 07, 12.5%) had the highest number of publications. The country that published the most was the United States (no. 16, 28.56%). The database with the most publications was the Cumulative Index to Nursing and Allied Health Literature - CINAHL (no. 15, 26.78%). The most used interventions, which had the most significant impact on the improvement of results and quality, were the use of indicators in all stages of the organ and tissue donation process; the use of real goals that can be achieved; frequent audits, validation of instruments to track opportunities for improvement; as well as methodologies to implement quality and education among professionals who work in this process. Such interventions reveal important changes in the organ donation process, especially in the notification of potential and effective donors, as well as providing an opportunity for safety in the stages of the organ and tissue donation process.

CONCLUSION

The interventions tracked suggest the implementation of a set of actions formed by the continuous use of auditing, indicators, continuing education with the team that works in the process of organ and tissue donation, combined with the management of the results obtained through the indicators, where it is generated from these data, actions that have a direct impact on the weaknesses identified.

Histological, Laboratorial, and Clinical Benefits of an Optimized Maintenance Strategy of a Potential Organ Donor-A Rabbit Experimental Model

INTRODUCTION

Most transplanted organs are obtained from brain-dead donors. Inflammation results in a higher rate of rejection. Objectives: The objective of this animal model of brain death (BD) was to evaluate the effect of the progressive institution of volume expansion, norepinephrine, and combined hormone therapy on clinical, laboratory, and histological aspects. Methods: Twenty rabbits were divided: A (control), B (induction of BD + infusion of crystalloid), C (BD + infusion of crystalloid and noradrenaline (NA)), and D (BD + infusion of crystalloid + vasopressin + levothyroxine + methylprednisolone + NA). The animals were monitored for four hours with consecutives analysis of vital signs and blood samples. The organs were evaluated by a pathologist. Results: In Group D, we observed fewer number and lesser volume of infusions (p = 0.032/0.014) when compared with groups B and C. Mean arterial pressure levels were higher in group D when compared with group B (p = 0.008). Group D had better glycemic control when compared with group C (p = 0.016). Sodium values were elevated in group B in relation to groups C and D (p = 0.021). In Group D, the organ perfusion was better. Conclusion: The optimized strategy of management of BD animals is associated with better hemodynamic, glycemic, and natremia control, besides reducing early signs of ischemia.

Recommendations for Evaluation and Selection of Deceased Organ Donor: Position Statement of ISCCM

There is a wide gap between patients who need transplants and the organs that are available in India. Extending the standard donation criterion is certainly important to address the scarcity of organs for transplantation. Intensivists play a major role in the success of deceased donor organ transplants. Recommendations for deceased donor organ evaluation are not discussed in most intensive care guidelines. The purpose of this position statement is to establish current evidence-based recommendations for multiprofessional critical care staff in the evaluation, assessment, and selection of potential organ donors. These recommendations will give "real-world" criteria that are acceptable in the Indian context. The aim of this set of recommendations is to both increase the number and enhance the quality of transplantable organs.

Hemodynamic management in brain dead donors

Donor management is the key in the complex donation process, since up to 20% of organs of brain death donors (DBD) are lost due to hemodynamic instability. This challenge is made more difficult due to the lack of strong recommendations on therapies for hemodynamic management in DBDs and more importantly to the epidemiologic changes in these donors who are becoming older and with more comorbidities (marginal donors). In the present manuscript we aimed at summarizing the available evidence on therapeutic strategies for hemodynamic management (focusing on vasoactive drugs) and monitoring (therapeutic goals). Evidence on management in elderly DBDs is also summarized. Donor management continues critical care but with different and specific therapeutic goals since the number of donor goals met is related to the number of organs retrieved and transplanted. Careful monitoring of selected parameters (possibly including serial echocardiography) is the clinical tool able to guarantee the achievement and maintaining of therapeutic goals. Despide worldwide differences, norepinephrine is the vasoactive of choice in most countries but, whenever higher doses (> 0.2 mcg/kg/min) are needed, a second vasoactive drug (vasopressin) is advisable. Hormonal therapy (desmopressin, corticosteroid and thyroid hormone) are suggested in all DBDs independently of hemodynamic instability. In the single patient, therapeutic regimen (imprimis vasoactive drugs) should be chosen also according to the potential organs retrievable (i.e. heart vs liver and kidneys).

[Organ donation: A treatment option in end-of life intensive care?]

A newly issued policy statement of the German Medical Association considers organ donation as an integral part of end-of-life intensive care in patients with devastating brain afflictions. Hence, patients' wishes towards organ donation and medical suitability should be evaluated when prognosis is considered futile and goals of treatment need to be reconsidered. Continuation of intensive care treatment towards the (mandatory) diagnosis of "brain death" and subsequently towards organ donation has to be legitimatized by patients' explicit wishes (organ donor card, advanced directive) or by surrogate decisions makers. Intensive care facilitating organ donation should be goal-directed and follow established guidelines. Thus, a potential recovery of transplantable organs is supported by appropriate intensive care treatment. Decisions to employ extended intensive care options (like extracorporeal circulatory support or cardiopulmonary resuscitation) in potential organ donors should be carefully outbalanced with patients' wishes, organ donation being considered an achievable goal and even potential frictions in medical teams.

New procedures for the confirmation of brain death in Brazil: results from the Central Estadual de Transplantes de Santa Catarina

Objective

To analyze the impact of Resolution 2.173/2017 of the Federal Council of Medicine on results from the Central Estadual de Transplantes de Santa Catarina.

Methods

This was a cross-sectional observational study of medical records of all patients (1,605) with suspected brain death notified to the Central Estadual de Transplantes de Santa Catarina; for this study, procedures to confirm this diagnosis were initiated between July 2016 and December 2017 and between January 2018 and June 2019. The median duration of the protocol in each period was considered for the comparison between the intervals. The collected data were transformed into rates (per million population). The mean rates for the periods before and after the implementation of the protocol were analyzed by Student’s t-test, and qualitative variables were analyzed by Pearson’s chi-squared test.

Results

The mean duration of brain death confirmation procedures decreased more than 1 hour in the second period compared to the first period, with statistical significance (p = 0.001). The rates of harvested livers and transplanted pancreas, the number of notifications by hospital size and the rate of cardiac arrest in the macro-region of the Itajaí Valley were significantly different between the two periods.

Conclusion

In the period after the new resolution on brain death, there was a reduction in the duration for diagnosis. However, other indicators did not change significantly, providing evidence for the multidimensional nature of the organ transplantation process in Santa Catarina and the need for further studies to better understand and optimize the process.

Bacterial Pneumonia in Brain-Dead Patients: Clinical Features and Impact on Lung Suitability for Donation

OBJECTIVES

To appraise the epidemiological features of bacterial pneumonia and its impact on lung suitability for donation in brain-dead patients managed with protective ventilatory settings.

DESIGN

Retrospective observational study.

SETTING

Six ICUs from two university-affiliated hospitals.

PATIENTS

Brain-dead adult patients managed in the participating ICUs over a 4-year period.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Among the 231 included patients, 145 (62.8%) were classified as ideal or extended-criteria potential lung donors at ICU admission and the remaining 86 patients having baseline contraindication for donation. Culture-proven aspiration pneumonia and early-onset ventilator-associated pneumonia occurred in 54 patients (23.4%) and 15 patients (6.5%), respectively (overall pneumonia incidence, 29.9%). Staphylococcus aureus and Enterobacterales were the most common pathogens. Using mixed-effects Cox proportional hazard models, age (adjusted hazard ratio, 0.98; 95% CI [0.96-0.99]), anoxic brain injury (3.55 [1.2-10.5]), aspiration (2.29 [1.22-4.29]), and not receiving antimicrobial agents at day 1 (3.56 [1.94-6.53]) were identified as independent predictors of pneumonia occurrence in the whole study population. Analyses restricted to potential lung donors yielded similar results. Pneumonia was associated with a postadmission decrease in the PaO2/FIO2 ratio and lower values at brain death, in the whole study population (estimated marginal mean, 294 [264-323] vs 365 [346-385] mm Hg in uninfected patients; p = 0.0005) as in potential lung donors (299 [248-350] vs 379 [350-408] mm Hg; p = 0.04; linear mixed models). Lungs were eventually retrieved in 31 patients (34.4%) among the 90 potential lung donors with at least one other organ harvested (pneumonia prevalence in lung donors (9.7%) vs nondonors (49.2%); p = 0.0002).

CONCLUSIONS

Pneumonia occurs in one-third of brain-dead patients and appears as the main reason for lung nonharvesting in those presenting as potential lung donors. The initiation of antimicrobial prophylaxis upon the first day of the ICU stay in comatose patients with severe brain injury could enlarge the pool of actual lung donors.

Unexpected cardio-circulatory arrest during a brain-dead donor organ retrieval

According to the Maastricht classification category of donation after circulatory death (DCD), type IV DCD refers to brain-dead donors who are re-categorized after unexpected circulatory arrest before donor organ retrieval. Clinical management is challenging, even in intensive care units, where most of this type of organ donation occurs. We report a case of the first successful lung transplantation (LTx) using type IV DCD organ in Taiwan. The recipient's recovery was satisfactory, without acute or chronic organ dysfunction. When unexpected events made the brain-dead donors suffer from sudden onset of cardiac arrest before or during organ donation surgery, immediately switching the retrieval protocol from donation after brain death (DBD) to DCD could expand the donor pool and increase organ supply. The well-prepared and experienced transplant team and prompt protocol switch made this transplant surgery possible.

Defining Quality Criteria for Success in Organ Donation Programs: A Scoping Review

Background

Well-established performance measures for organ donation programs do not fully address the complexity and multifactorial nature of organ donation programs such as the influence of relationships and organizational attributes.

Objective

To synthesize the current evidence on key organizational attributes and processes of international organ donation programs associated with successful outcomes and to generate a framework to categorize those attributes.

Design

Scoping Review using a mixed methods approach for data extraction.

Setting

Databases included PubMed, CINAHL, Embase, LILACS, ABI Business ProQuest, Business Source Premier, and gray literature (organ donation association websites, Google Scholar-first 8 pages), and searches for gray literature were performed, and relevant websites were perused.

Sample

Organ donation programs or processes.

Methods

We systematically searched the literature to identify any research design, including text and opinion papers and unpublished material (research data, reports, institutional protocols, government documents, etc). Searches were completed on January 2018, updated it in May 2019, and lastly in March 2020. Title, abstracts, and full texts were screened independently by 2 reviewers with disagreements resolved by a third. Data extraction followed a mixed method approach in which we extracted specific details about study characteristics such as type of research, year of publication, origin/country of study, type of journal published, and key findings. Studies included considered definitions and descriptions of success in organ donation programs in any country by considering studies that described (1) attributes associated with success or effectiveness, (2) organ donation processes, (3) quality improvement initiatives, (4) definitions of organ donation program effectiveness, (5) evidence-based practices in organ donation, and (6) improvements or success in such programs. We tabulated the type and frequency of the presence or absence of reported improvement quality indicators and used a qualitative thematic analysis approach to synthesize results.

Results

A total of 84 articles were included. Quantitative analysis identified that most of the included articles originated from the United States (n = 32, 38%), used quantitative approaches (n = 46, 55%), and were published in transplant journals (n = 34, 40.5%). Qualitative analysis revealed 16 categories that were described as positively influencing success/effectiveness of organ donation programs. Our thematic analysis identified 16 attributes across the 84 articles, which were grouped into 3 categories influencing organ donation programs' success: context (n = 39, 46%), process (n = 48, 57%), and structural (n = 59, 70%).

Limitations

Consistent with scoping review methodology, the methodological quality of included studies was not assessed.

Conclusions

This scoping review identified a number of factors that led to successful outcomes. However, those factors were rarely studied in combination representing a gap in the literature. Therefore, we suggest the development and reporting of primary research investigating and measuring those attributes associated with the performance of organ donation programs holistically.

Clinical Impacts and Outcomes With Possible Donor-Derived Infection in Infected Donor Liver Transplantation: A Single-Center Retrospective Study in China

BACKGROUND

Information on possible donor-derived transmission events in China is limited. We evaluated the impacts of liver transplantation from infected deceased-donors, analyzed possible donor-derived bacterial or fungal infection events in recipients, and evaluated the etiologic agents' characteristics and cases outcomes.

METHODS

A single-center observational study was performed from January 2015 to March 2017 to retrospectively collect data from deceased-donors diagnosed with infection. Clinical data were recorded for each culture-positive donor and the matched liver recipient. The microorganisms were isolated and identified, and antibiotic sensitivity testing was performed. The pathogens distribution and incidence of possible donor-derived infection (P-DDI) events were analyzed and evaluated.

RESULTS

Information from 211 donors was collected. Of these, 82 donors were infected and classified as the donation after brain death category. Overall, 149 and 138 pathogens were isolated from 82 infected donors and 82 matched liver recipients, respectively. Gram-positive bacteria, Gram-negative bacteria, and fungi accounted for 42.3% (63 of 149), 46.3% (69 of 149), and 11.4% (17 of 149) of pathogens in infected donors. The incidence of multidrug-resistant bacteria was high and Acinetobacter baumannii was the most concerning species. Infections occurred within the first 2 weeks after liver transplantation with an organ from an infected donor. Compared with the noninfection recipient group, the infection recipient group experienced a longer mechanical ventilation time (P = .004) and intensive care unit stay (P = .003), a higher incidence of renal dysfunction (P = .026) and renal replacement therapy (P = .001), and higher hospital mortality (P = .015). Possible donor-derived infection was observed in 14.6% of cases. Recipients with acute-on-chronic liver failure were more prone to have P-DDI than recipients with other diseases (P = .007; odds ratio = 0.114; 95% confidence interval, .025-.529).

CONCLUSIONS

When a liver recipient receives a graft from an infected deceased-donor, the postoperative incidence of infection is high and the infection interval is short. In addition, when a possible donor-derived, drug-resistant bacterial infection occurs, recipients may have serious complications and poor outcomes.

Organ donation in the US and Europe: The supply vs demand imbalance

Organ donation and transplantation remain the best and most cost-effective clinical solution for end-stage organ failure. Several agencies across the US and Europe provide legislative, regulatory, and humanitarian services to generate smoother applications in all transplantation processes and donor-recipient relationships. US and European statistics present nine types of grafts, with kidneys being the most transplanted organ worldwide. However, organ shortage, religion, underrepresented minority groups, difficulties in obtaining consent, lack of understanding, and general ethical concerns present challenging barriers to organ donation, reflecting the complexity of graft procurement and allocation. Breaking down these barriers to reduce the organ-supply imbalance requires an appropriate multifaceted approach. Some of the key areas include increasing the potential donor pool and consent rates, apt organ allocation, and improving organ health. Additionally, suitable policies and standardized guidelines for both donors and recipients, alongside educational initiatives, are needed to ensure patient safety and global awareness. Looking forward, novel and effective research plans and initiatives are needed if we are to avoid a colossal supply-demand gap.

Variability in deceased donor care in Canada: a report of the Canada-DONATE cohort study

PURPOSE

Canadian donor management practices have not been reported. Our aim was to inform clinicians and other stakeholders about the range of current practices.

METHODS

This prospective observational cohort study enrolled consecutive, newly consented organ donors from August 1 2015 to July 31 2018 at 27 academic and five community adult intensive care units in British Columbia, Alberta, Ontario, and Quebec. Research staff prospectively recorded donor management data. Provincial organ donation organizations verified the organs donated. We formally compared practices across provinces.

RESULTS

Over a median collection period of eight months, 622 potential donors were classified at baseline as having neurologic determination of death (NDD donors; n = 403) or circulatory death (DCD donors; n = 219). Among NDD donors, 85.6% underwent apnea testing (rarely with carbon dioxide insufflation), 33.2% underwent ancillary testing, and subsequent therapeutic hypothermia (34-35°C) was rare. Neurologic determination of death donors were more hemodynamically unstable with most having received vasopressin and norepinephrine infusions, with a large majority having received high-dose corticosteroids and intravenous thyroxine. Among DCD donors, 61.6% received corticosteroids, and 8.9% received thyroxine. Most donors did not receive lung-protective ventilation strategies. Invasive procedures after donation consent included bronchoscopy (71.7%), cardiac catheterization (NDD donors only; 21.3%), and blood transfusions (19.3%). Physicians ordered intravenous antemortem heparin for 94.8% of DCD donors. The cohort donated 1,629 organs resulting in 1,532 transplants. Case selection, death determinations, and hormone, nutrition and heparin practices all varied across provinces.

CONCLUSION

These study findings highlight areas for knowledge translation and further clinical research. Interprovincial discrepancies will likely pose unique challenges to national randomized trials.

Increase in Cadaver Organ Donation Rate at a Tertiary Care Hospital: 23 Years of Experience

Background

Transplantation of Human Organ Act was passed in India in 1994 to streamline organ donation and transplantation activities. It is time to retrospect ourselves and analyze the method to increase organ donation.

Type of study

Retrospective observational analysis.

Objectives

To evaluate the change in organ donation rate and reasons for changes in rates.

Subjects

Brainstem dead declared patients whose family consented for organ donations in the last 23 years (1997–2019) at Ruby Hall Clinic, Pune, India.

Materials and methods

Retrospectively demographic data of the brainstem dead declared donors, the primary diagnoses, comorbidities, and the complete data of their management till organ retrieval was assessed.

Results

One hundred cases in the age group 15–75 years (mean 41.6 ± 15.3 years) of brainstem death consented for organ donation were retrospectively studied. The period was divided into two groups, group I and group II included study duration from 1997 to 2013 and from 2013 to 2019 respectively. During the entire period, though the major cause of donor death remained road traffic accidents (RTA) in both the groups (84.21% till 2013 vs 48.15% after 2013), the proportion of donors declared brain dead due to RTA dipped significantly after 2013 (p = 0.004) and the non-RTA causes of brain dead contributed more than RTA causes (51.85% non-RTA vs 48.15% RTA). The major contributor among non-RTA causes was intracranial bleeds (5.26% before 2013 vs 33.33% after 2013, p = 0.014). Compared to the previous 17 years (from 1997) there were more than fourfold rise in the rate of transplantation in the last 6 years (2014–2019) at our institute. Kidneys were retrieved from 90% donors followed by cornea 84%, liver 65%, heart 22%, skin 7%, lungs 6%, and pancreas 5%.

Conclusion

We have observed that the cadaveric organ donation rate significantly improved after 2013. Reasons might be widening of the donor pool by the selection of more of non-RTA brain death donors over RTA, acceptability of elderly population donor (>60 years) by our transplant teams, early identification of potential organ donor, and better protocol-based management of the cadaver organ donor.
