Singh MK, Kane JM, Said SJ. Pediatric Lead Chelation Managed During Critical Medication Shortages: Case Report and Literature Review. J Pediatr Pharmacol Ther 2024; 29:544-549.

Abstract
Lead poisoning in children has the potential for devastating neurodevelopmental consequences. There is significant socioeconomic disparity in children with lead poisoning. Specific lead chelation regimens have been approved for children by the US Food and Drug Administration, however in the United States, there has been a recent national shortage of the primary therapy, edetate calcium disodium (CaNa2 EDTA). This case report presents a 23-month-old child with severe symptomatic lead poisoning during a national shortage of CaNa2 EDTA to highlight the need for advocacy regarding critical medication shortages, especially for antidote therapy. The infant's initial blood lead level was 364 mcg/dL and he received a continuous infusion of CaNa2 EDTA (1000 mg/m2/day), as well as dimercaprol (4 mg/kg intramuscularly every 4 hours). The supply of CaNa2 EDTA was exhausted on day 3 of therapy so he was transitioned to enteral succimer monotherapy. Initial parenteral therapy of 72 hours achieved a lead level of 72 mcg/dL; he then completed his enteral course of succimer along with environmental mitigation. However, elevated blood lead levels persisted and he subsequently required 3 more courses of enteral succimer, and he continues to have detectable blood lead levels 2 years after initial presentation. In the face of medication shortages including CaNa2 EDTA, and now also dimercaprol, clinicians must create and study alternative chelation therapy regimens for pediatric lead toxicity. Furthermore, public policy initiatives, including the development of a national supply stockpile of chelation agents, must be created in order to minimize supply chain disruption and ensure adequate and equitable antidote therapy for lead poisoning outbreaks.

Adverse drug effect in the context of drug shortage: the CIRUPT prospective study from the French pharmacovigilance network. Eur J Hosp Pharm 2024:ejhpharm-2023-004047. [PMID: 38621957 DOI: 10.1136/ejhpharm-2023-004047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Accepted: 04/02/2024] [Indexed: 04/17/2024] Open
Abstract
OBJECTIVES Drug shortages are of increasing concern to worldwide public health. The consequences of drug shortages for patient safety have been little studied, especially from a pharmacovigilance point of view. In this context, the network of French pharmacovigilance centres conducted the CIRUPT study (Conséquences Iatrogènes des RUPTures de stock/iatrogenic consequences of drug shortages) based on a prospective campaign of adverse effects occurring in the context of drug shortage notifications. METHODS All notifications involving a shortage drug submitted to the French pharmacovigilance centres between 1 January 2020 and 30 June 2021 were collected and registered in the French national pharmacovigilance database with the standardised high level term 'product supply and availability issues' and with predefined keywords in the narrative section. RESULTS 224 cases were included, involving mainly adverse drug reactions (ADRs) (n=131/224, 59%) and medication errors (n=51/224, 23%); 29% of the cases were serious. The most represented classes of shortage drugs were: vaccines (n=78/224, 35%); drugs for acid-related disorders (H2-receptor antagonists) (n=27/224, 12%); antineoplastic agents (n=17/224, 8%); and antiepileptics (n=15/224, 7%). In 82% of cases, the involved shortage drug was the subject of information delivered to health professionals by the National Agency for the Safety of Medicines and Health Products. Drug shortages were associated with an ADR related to replacement drugs in 59% (n=131/224) of the cases, drug inefficacy in 18% (n=41/224), and/or an aggravation of the underlying disease in 11% (n=25/224). CONCLUSIONS From a pharmacovigilance point of view, a large diversity of anatomical therapeutic classes is involved and the risk related to drug shortages is not limited to drugs registered on 'major therapeutic interest or essential drug' lists. Information from health agencies is not sufficient to avoid the risks, and further strategies should be developed.

Abstract
BACKGROUND Antibacterial therapy plays a crucial role in neonatal infections. The efficacy of antibacterial agents is closely related to the actual dose given to neonates. So we evaluated factors potentially affecting the actual dose of intravenous antibiotics during dispensing process in neonates. METHODS Meropenem, cefoperazone/sulbactam and piperacillin/tazobactam with two strengths were used to evaluate three methods. Method A (MA) was diluted once and the volumes of 5% glucose for MA were meropenem 4.00 mL, cefoperazone/sulbactam 3.00 mL, piperacillin/tazobactam 9.00 mL. Method B (MB) differed by doubling the volume of 5% glucose. The difference in method C (MC) involved diluting with 5% glucose twice. The concentrations were measured by high-performance liquid chromatography. Relative error (RE) was used to evaluate the preparation accuracy. RESULTS The RE values using MA/MB/MC were: (1) meropenem 0.5 g: 15.1%, 8.0%, 10.4%; 0.25 g: 7.8%, 3.1%, 6.0%; (2) cefoperazone/sulbactam 1.5 g: 13.6%, 4.2%, 3.4%; 0.75 g: 8.8%, 3.5%, 4.0%; (3) piperacillin/tazobactam 4.5 g: 18.2%, 8.7%, 6.3%; 562.5 mg: 8.1%, 2.8%, 6.1%. MB was better than MA in all three drugs. No difference in RE values was found between single and double dilution, except meropenem with 0.25 g. Using MB, meropenem and piperacillin/tazobactam with small drug strength had higher accuracy in preparation. CONCLUSIONS MB was suitable for neonatal drug dispensing because of its high accuracy and simple operation. Drugs with small strength were promoted due to the high accuracy.

Abstract
Shortages and rationing are common in health care, yet we know little about the consequences. We examine an 18-month shortage of the pediatric Haemophilus Influenzae Type B (Hib) vaccine. Using insurance claims data and variation in shortage exposure across birth cohorts, we find that the shortage reduced uptake of high-value primary doses by 4 percentage points and low-value booster doses by 26 percentage points. This suggests providers largely complied with rationing recommendations. In the long-run, catch-up vaccination occurred but was incomplete: shortage-exposed cohorts were 4 percentage points less likely to have received the ir booster dose years later. We also find that the shortage and rationing caused provider switches, extra provider visits, and negative spillovers to other care.

J Pain Palliat Care Pharmacother 2023; 37:336-341.

Abstract
Given the rising frequency of drug shortages in hospitals, interdisciplinary collaboration is necessary to manage medications, modify electronic medical records, and evaluate safety outcomes. One such shortage impacted lorazepam injection, a medication commonly used in palliative care to treat anxiety, agitation, and seizures. In anticipation of the lorazepam shortage in the summer of 2022, pharmacy staff collaborated with palliative care physicians to identify alternative treatment recommendations when providers were prohibited from ordering lorazepam injection. Before the shortage, lorazepam was used an average of 95 times per month on the palliative care unit. The overall use of benzodiazepines decreased substantially following the recommendation for the therapeutic alternative, midazolam, during the shortage. Once the shortage ended, use roughly returned to pre-shortage baselines. During this time, there were no patient safety events documented on the palliative care unit. Moreover, no changes to the care experience were reported by patients, family/caregivers, providers, or staff. The collaborative effort between pharmacy and palliative care specialists resulted in alternative treatments for palliative care patients during the drug shortage. This preserved the hospital's supply of lorazepam injection for a patient population with no suitable alternatives while still allowing for management of palliative patients.

Abstract
BACKGROUND Intermittent shortages of chemotherapeutics used to treat curable malignancies are a worldwide problem that increases patient mortality. Although multiple strategies have been proposed for managing these shortages (eg, prioritizing patients by age, scarce treatment efficacy per volume, alternative treatment efficacy difference), critical clinical dilemmas arise when selecting a management strategy and understanding its impact. PATIENTS AND METHODS We developed a model to compare the impact of different allocation strategies on overall survival during intermittent chemotherapy shortages and tested it using vincristine, which was recently scarce for 9 months in the United States. Demographic and treatment data were abstracted from 1,689 previously treated patients in our tertiary-care system; alternatives were abstracted from NCCN Clinical Practice Guidelines in Oncology for each disease and survival probabilities from the studies cited therein. Modeled survival was validated using SEER data. Nine-month shortages were modeled for all possible supply levels. Pairwise differences in 3-year survival and risk reductions were calculated for each strategy compared with standard practice (first-come, first-served) for each 50-mg supply increment, as were supply thresholds above which each strategy maintained survival similar to scenarios without shortages. RESULTS A strategy prioritizing by higher vincristine efficacy per volume and greater alternative treatment efficacy difference performed best, improving survival significantly (P<.01) across 86.5% of possible shortages (relative risk reduction, 8.3%; 99% CI, 8.0-8.5) compared with standard practice. This strategy also maintained survival rates similar to a model without shortages until supply fell below 72.2% of the amount required to treat all patients, compared with 94.3% for standard practice. CONCLUSIONS During modeled vincristine shortages, prioritizing patients by higher efficacy per volume and alternative treatment efficacy difference significantly improved survival over standard practice. This approach can help optimize allocation as intermittent chemotherapy shortages continue to arise.

Abstract
PURPOSE Pharmacy departments across the country are problem-solving the growing issue of drug shortages. We aim to change the drug shortage management strategy from a reactive process to a more proactive approach using predictive data analytics. By doing so, we can drive our decision-making to more efficiently manage drug shortages. METHODS Internal purchasing, formulary, and drug shortage data were reviewed to identify drugs subject to a high shortage risk ("shortage drugs") or not subject to a high shortage risk ("nonshortage drugs"). Potential candidate predictors of drug shortage risk were collected from previous literature. The dataset was trained and tested using 2 methods, including k-fold cross-validation and a 70/30 partition into a training dataset and a testing dataset, respectively. RESULTS A total of 1,517 shortage and nonshortage drugs were included. The following candidate predictors were used to build the dataset: dosage form, therapeutic class, controlled substance schedule (Schedule II or Schedules III-V), orphan drug status, generic versus branded status, and number of manufacturers. Predictors that positively predicted shortages included classification of drugs as intravenous-only, both oral and intravenous, antimicrobials, analgesics, electrolytes, anesthetics, and cardiovascular agents. Predictors that negatively predicted a shortage included classification as an oral-only agent, branded-only agent, antipsychotic, Schedule II agent, or orphan drug, as well as the total number of manufacturers. The calculated sensitivity was 0.71; the specificity, 0.93; the accuracy, 0.87; and the C statistic, 0.93. CONCLUSION The study demonstrated the use of predictive analytics to create a drug shortage model using drug characteristics and manufacturing variables.

Abstract
Drug shortages frequently and persistently affect healthcare institutions, posing formidable financial, logistical, and ethical challenges. Despite plentiful evidence characterizing the impact of drug shortages, there is a remarkable dearth of data describing current shortage management practices. Hospitals within the same state or region may not only take different approaches to shortages but may be unaware of shortages proximate facilities are facing. Our goal is to explore how hospitals in Michigan handle drug shortages to assess potential need for comprehensive drug shortage management resources. We conducted semi-structured interviews with diverse stakeholders throughout the state to describe experiences managing drug shortages, approaches to recent shortages, openness to inter-institutional engagement, ideas for a shared resource, and potential obstacles to implementation. To solicit additional feedback on ideas for a shared resource gathered from the interviews, we held focus groups with pharmacists, physicians, ethicists, and community representatives. Among participants representing a heterogeneous sample of institutions, three themes were consistent: (1) numerous drug shortage strategies occurring simultaneously; (2) inadequate resources and lead time to proactively manage shortages; and (3) interest in, but varied attitudes toward, a collaborative approach. These data provide insight to help develop and test a shared drug shortage management resource for enhancing fair allocation of scarce drugs. A shared resource may help institutions adopt accepted best practices and more efficiently access or share finite resources in times of shortage.

Abstract
PURPOSE Management of an acute shortage of parenteral opioid products at a large hospital through prescribing interventions and other guideline-recommended actions is described. SUMMARY In early 2018, many hospitals were faced with a shortage of parenteral opioids that was predicted to last an entire year. The American Society of Health-System Pharmacists (ASHP) has published guidelines on managing drug product shortages. This article describes the application of these guidelines to manage the parenteral opioid shortage and the impact on opioid dispensing that occurred in 2018. Our approach paralleled that recommended in the ASHP guidelines. Daily dispensing reports generated from automated dispensing cabinets and from the electronic health record were used to capture dispenses of opioid medications. Opioid prescribing and utilization data were converted to morphine milligram equivalents (MME) to allow clinical leaders and hospital administrators to quickly evaluate opioid inventories and consumption. Action steps included utilization of substitute opioid therapies and conversion of opioid patient-controlled analgesia (PCA) and opioid infusions to intravenous bolus dose administration. Parenteral opioid supplies were successfully rationed so that surgical and elective procedures were not canceled or delayed. During the shortage, opioid dispensing decreased in the inpatient care areas from approximately 2.0 million MME to 1.4 million MME and in the operating rooms from 0.56 MME to 0.29 million MME. The combination of electronic health record alerts, increased utilization of intravenous acetaminophen and liposomal bupivacaine, and pharmacist interventions resulted in a 67% decline in PCA use and a 65% decline in opioid infusions. CONCLUSION A multidisciplinary response is necessary for effective management of drug shortages through implementation of strategies and practices for notifying clinicians of shortages and identifying optimal alternative therapies.

JOURNAL OF MEDICAL ETHICS 2020; 47:medethics-2020-106739.

Abstract
Hospital systems commonly face the challenge of determining just ways to allocate scarce drugs during national shortages. There is no standardised approach of how this should be instituted, but principles of distributive justice are commonly used so that patients who are most likely to benefit from the drug receive it. As a result, clinical indications, in which the evidence for the drug is assumed to be established, are often prioritised over research use. In this manuscript, we present a case of a phase II investigational trial of intravenous thiamine for delirium prevention in patients undergoing haematopoietic stem cell transplantation to emphasise several shortcomings in the overarching prioritisation of clinical over research uses of scarce drugs. Specifically, we present the following considerations: (1) clinical use may not have stronger evidence than research use; (2) a strong scientific rationale for research use may outweigh the claim for clinical indications in which there is weak evidence; (3) treatment within the context of a clinical trial may be the standard of care; and (4) research use may not only benefit patients receiving the treatment but also offers the prospect of improving future clinical care. In summary, we argue against allocation schemes that prohibit all research uses of scarce drugs and instead recommend that allocation schemes include a balanced approach that weighs risks and benefits of access to scarce drugs irrespective of the research versus clinical use designation.

Abstract
BACKGROUND In the face of ongoing drug shortages, anesthesiologists have been described as having to become "Iron Chefs, challenged to create safe patient outcomes with missing ingredients. Unfortunately, developing responsive ethical guidance for how anesthesiologists should best handle ethical concerns with ongoing and mutable drug shortages is limited by the dearth of studies examining how bedside clinicians actually experience drug shortages and what ethical challenges they encounter. In order to better understand what ethical concerns individual anesthesiologists experience around drug shortages and how they negotiate them, we undertook this qualitative interview study. Methods: We conducted semi-structured interviews with anesthesiologists at three field sites: an academic tertiary care adult hospital that performs approximately 46,000 anesthetics annually comprising cases ranging across all surgical disciplines; the affiliated veteran's affairs hospital that performs 12,000 anesthetics annually; and, the affiliated children's hospital that performs 20,500 anesthetics annually. Results: 29 anesthesiologists were interviewed (17 adult and 12 pediatric anesthesiologists), representing a spectrum of practice areas in clinical anesthesia: general, pediatric, regional, pain, critical care, obstetrics, liver transplant, and palliative medicine. Three themes emerged: (1) uncertainty about responsibility for clinical decisions made in consequence to a shortage; (2) creativity, and its limits, in choosing anesthetic plans; and, (3) disclosure of concerns about shortages (to patients and colleagues). Conclusions: Our data suggests anesthesiologists have unmet needs for ethical guidance on how to approach drug shortages. First is managing responsibility for decisions stemming from a drug shortage. Second, interviewees struggled with disclosure of their concerns, both to patients and to surgical colleagues. A formal shared decision making approach may present the best solution, since the act of structuring a shared decision making conversation or creating a decision making tool will have to incorporate the views of all stakeholders around shortages and their potential clinical consequences.

Abstract
In Germany, ~8 million patients take angiotensin receptor blockers (ARBs) and 2.25 million of them valsartan. In 2018, contamination of generic ARBs with probable carcinogenic nitrosamines resulted in more than 30 recalls. The impact of such a huge recall has never been explored in Europe. We analyzed the utilization of valsartan, all ARBs, and other alternative antihypertensive drugs in Germany. We used our database of anonymized dispensing data from >80% of community pharmacies at the expense of the statutory health insurance (SHI) funds from January 2017 to December 2019. We analyzed 290.8 million prescriptions, including all oral mono- and fixed-dose combinations of ARBs and plausible alternatives, i.e. ACE inhibitors (ACEi), beta-blockers (BB), and calcium channel blockers (CCB). Utilization was calculated by defined daily doses per 1000 SHI-insured persons per day (DID). Valsartan use decreased substantially after the recalls in July 2018 from 39.0 to 14.2 DID (−64%) in the second quarter of 2019 and to 16.9 DID (−57%) in the fourth quarter of 2019. Simultaneously, the use of alternative ARBs increased from 77.7 DID in the second quarter of 2018 to 121.9 DID (+57%) in the fourth quarter of 2019, mainly due to an increase of candesartan dispensing to 99.8 DID (+73%). There were no changes in the utilization of ACEi, BB, or CCB. The majority of recalled generic valsartan products were replaced by other ARBs, predominantly candesartan, despite documented drug shortages. In contrast to previous safety warnings/recalls, our data do not suggest an under-prescription of antihypertensives during this period.

Abstract
PURPOSE: Medication shortages in US hospitals are ongoing, widespread, and frequently involve antineoplastic and supportive medications used in cancer care. The ways shortages are managed and the ways provider-patient communication takes place are heterogeneous, but the related preferences of oncology patients are undefined. This study sought to qualitatively evaluate patient preferences. METHODS: A cross-sectional, semi-structured interview study was conducted from January to June 2019. Participants were adult oncology inpatients who received primary cancer care at the University of Chicago, had undergone treatment within 2 years, and had 1 or more previous hospitalizations during that period. Participants (n = 54) were selected consecutively from alternating hematology and oncology services. The primary outcome was thematic saturation across the domains of awareness of medication shortages, principle preferences regarding decision makers, preferences regarding allocation of therapy drugs, and allocation-related communication. RESULTS: Thematic saturation was reached after 39 participants completed the study procedures (mean age, 59.6 years [standard deviation, 14.5 years]; men made up 61.5% of the study population [mean age, 24 years]; response rate, 72.0%). In all, 18% of participants were aware of institutional medication shortages. Patients preferred having multiple decision makers for allocating medications in the event of a shortage. A majority of patients named oncologists (100%), ethicists (92%), non-oncology physicians (77%), and pharmacists (64%) as their preferred decision makers. Participants favored allocation of drugs based on their efficacy (normalized weighted average, 1.3), and they also favored prioritizing people who were already receiving treatment (1.8), younger patients (2.0), sicker patients (3.1), and those presenting first for treatment (5.3). Most participants preferred preferred disclosure of supportive care medication shortages (74%) and antineoplastic medication shortages (79%) for equivalent substitutions. CONCLUSION: In a tertiary-care center with medication shortages, few oncologic inpatients were aware of shortages. Participants preferred having multiple decision makers involved in principle-driven allocation of scarce medications. Disclosure was preferred when their usual medications needed to be substituted with equivalent alternatives. These preliminary data suggest that preferences do not align with current management practices for medication shortages.

Abstract
The United States has experienced prolonged severe shortages of vital medications over the past two decades. The causes underlying the severity and prolongation of these shortages are complex, in part due to the complexity of the underlying supply chain networks, which involve supplier-buyer interactions across multiple entities with competitive and cooperative goals. This leads to interesting challenges in maintaining consistent interactions and trust among the entities. Furthermore, disruptions in supply chains influence trust by inducing over-reactive behaviors across the network, thereby impacting the ability to consistently meet the resulting fluctuating demand. To explore these issues, we model a pharmaceutical supply chain with boundedly rational artificial decision makers capable of reasoning about the motivations and behaviors of others. We use multiagent simulations where each agent represents a key decision maker in a pharmaceutical supply chain. The agents possess a Theory-of-Mind capability to reason about the beliefs, and past and future behaviors of other agents, which allows them to assess other agents’ trustworthiness. Further, each agent has beliefs about others’ perceptions of its own trustworthiness that, in turn, impact its behavior. Our experiments reveal several counter-intuitive results showing how small, local disruptions can have cascading global consequences that persist over time. For example, a buyer, to protect itself from disruptions, may dynamically shift to ordering from suppliers with a higher perceived trustworthiness, while the supplier may prefer buyers with more stable ordering behavior. This asymmetry can put the trust-sensitive buyer at a disadvantage during shortages. Further, we demonstrate how the timing and scale of disruptions interact with a buyer’s sensitivity to trustworthiness. This interaction can engender different behaviors and impact the overall supply chain performance, either prolonging and exacerbating even small local disruptions, or mitigating a disruption’s effects. Additionally, we discuss the implications of these results for supply chain operations.

Abstract
BACKGROUND Medication shortages prevent patients from receiving optimal care. Despite the frequency with which medical trainees care for inpatients, no assessment of their experiences in medication shortage management has been performed. OBJECTIVE We evaluated trainees' experiences managing medication shortages. METHODS We performed a cross-sectional survey of trainees postgraduate year 2 (PGY-2) and above in medicine, anesthesiology, and emergency medicine departments at 2 academic centers in 2018-2019. Categorical and ordinal assessments evaluated shortage awareness, substitution availability, pharmacy and therapeutics committee-based restrictions, communication, and education. Regressions were performed to determine effect of PGY, department, and institution on responses. RESULTS A total of 168 of 273 subjects completed the survey (62% response rate). Most (95%, 159 of 168) reported managing medication shortages during training; 51% (86 of 168) described managing clinically relevant shortages daily or weekly. Seventy-seven percent (129 of 168) noted equivalent alternatives were unavailable at least one-quarter of the time, and 43% (72 of 168) reported clinically necessary medications were restricted at least weekly. Fifty-four percent (89 of 168) and 64% (106 of 167) of respondents discussed clinically relevant shortages with supervising physicians or patients "some of the time" or less, respectively. Most respondents (90%, 151 of 168) reported they would benefit from shortage management training, but few (13%, 21 of 168) reported prior training. CONCLUSIONS Although trainees reported frequent involvement in clinically impactful shortage management, medication shortage communication between trainees and supervising physicians or patients appears sporadic. Medication shortage management training is uncommon but perceived as beneficial.
