Organizational Adaptive Capacity during a Large-Scale Surprise Event: A Case Study at an Academic Institution during the COVID-19 Pandemic

OCCUPATIONAL APPLICATIONSThe COVID-19 pandemic caused large organizations and institutions to adapt their decision-making procedures and hierarchical structures to address pandemic-specific concerns. By examining a large public university, we found that effective adaptation occurred through restructuring the decision-making processes, coordinating decisions between departments, and effective monitoring of prior decisions. When considering the COVID-19 pandemic as a fundamental surprise event, our work identified strategies and decision-making that both maintained and increased adaptive capacity through the course of such an event. Through this case study, we highlight decisions that can be made by similar large organizations, to increase adaptive capacity when they are faced with similar surprise events.

Drug shortages in low- and middle-income countries: Colombia as a case study

Background

Drug shortages are a global problem. Analyzing shortages worldwide is important to identify possible relationships between drug shortages across countries, determine strategies that reduce drug shortages, and reduce the inequality in access to medicines between countries. In contrast to well-documented shortages in high-income countries, there are few studies that consider low- and middle-income economies. We evaluate drug shortages in one middle-income country, Colombia.

Methods

We collected data from INVIMA, the institution responsible for managing medicine shortage alerts in Colombia. We classified the data using the Anatomical Therapeutic Chemical (ATC) classification system and analyzed them using descriptive statistics. We considered a study period from 2015 to 2021 (vital medicines) and from 2010 to 2020 (non-vital medicines).

Results

In total, 173 unique ATC codes were in shortage. These included antidotes, alimentary tract and metabolism products, anesthetics, cardiac stimulants and antithrombotic agents. The major causes were manufacturing problems and few suppliers. Drug shortages substantially increased from 2020 to May 2021 due to the COVID-19 pandemic. Among resolved shortages, the average duration was 1.6 years with a standard deviation of 1.9 years. The longest, naloxone tablets, were in shortage for almost 10 years.

Conclusions

Drug shortages are a persistent problem in Colombia. Government institutions have made progress in implementing systems and procedures to report them. However, the approaches implemented need to be maintained and refined. This study lays the groundwork for the analysis of drug shortages in other LMICs. We highlight the necessity of addressing drug shortages in their global context and reducing the inequality in access to medicines between countries.

A componential approach for evaluating the sources of trace metals in municipal solid waste

Trace metals concentrations of 25 elements were determined for 22 subcomponents of biodegradable and non-biodegradable waste samples representing the United States municipal solid waste (MSW) stream collected during three separate waste sorts. The subcomponent trace metal concentrations and estimated composition results were used to predict trace metal concentrations present in the overall MSW stream along with MSW compost and waste to energy (WTE) ash, which were compared to health-based standards (i.e., US EPA regional screening levels) and to values previously reported in the literature. These estimates for potentially problematic elements like As and Sb could be attributed to abundant base materials in MSW, while other elements, such as Pb, were calculated at much lower concentrations than other published studies. This suggests that trace metals measured in actual MSW compost and WTE ash could originate not only from MSW base components but also from other sources, such as highly concentrated low-mass wastes (e.g., e-waste). While the removal of small quantity components with high metal concentrations may reduce concentrations of some potentially problematic metals (e.g., Pb), others (e.g., As and Sb) are likely to persist in quantities that impede reuse and recycling since they are present in the more abundant base MSW components (e.g., papers, plastics, organics). Promoting meaningful reductions in potentially problematic trace metals in MSW-derived materials may require reevaluating their presence in higher-volume, lower-concentrated MSW components such as paper, plastics, and organics.

Life and expectations post-kidney transplant: a qualitative analysis of patient responses

BACKGROUND

The effect of a kidney transplant on a recipient extends beyond the restoration of kidney function. However, there is limited qualitative analysis of recipient perspectives on life following transplantation, particularly in the United States. To understand the full patient experience, it is necessary to understand recipient views on life adjustments after kidney transplantation, medical management, and quality of life. This could lead to improvements in recipient care and sense of well-being.

METHODS

We conducted a paper-based survey from March 23 to October 1, 2015 of 476 kidney transplant recipients at the University of Michigan Health System in Ann Arbor, Michigan. We analyzed their open-ended responses using qualitative research methods. This is a companion analysis to a previous quantitative report on the closed-ended responses to that survey.

RESULTS

Common themes relating to changes following transplantation included: improvements in quality of life, a return to normalcy, better health and more energy. Concerns included: duration of graft survival, fears about one day returning to dialysis or needing to undergo another kidney transplant, comorbidities, future quality of life, and the cost and quality of their healthcare. Many recipients were grateful for their transplant, but some were anxious about the burdens transplantation placed on their loved ones.

CONCLUSIONS

While most recipients reported meaningful improvements in health and lifestyle after kidney transplantation, a minority of participants experienced declines in energy or health status. Worries about how long the transplant will function, future health, and cost and quality of healthcare are prevalent. Future research could study the effects of providing additional information, programs, and interventions following transplantation that target these concerns. This may better prepare and support kidney recipients and lead to improvements in the patient experience.

Comparison of patient and provider goals, expectations, and experiences following kidney transplantation

OBJECTIVE

This study examined whether kidney transplant recipients' post-transplant goals and expectations align with those as perceived by their healthcare providers.

METHODS

Post-transplant goals and expectations across four domains were assessed via a descriptive survey of healthcare providers (N=72) and kidney transplant recipients (N=476) at the University of Michigan from March 23 - October 1, 2015. Demographic and transplant-related data were collected via a retrospective review of medical records, and survey responses were compared using Chi-square tests, Wilcoxon two-sample tests, and logistic regression.

RESULTS

Patients expressed higher quality of life (mean Neuro-QOL T-score 60.2 vs. 52.7), were less likely to report that they were currently experiencing complications (11% vs. 24%), and anticipated their transplants to last longer (median 25 vs. 15 years) and to live longer (median 80 vs. 71 years) than providers expected for their typical patient. However, provider perceptions of patients' future ability to feel well, perform daily activities and work were significantly higher than those expressed by patients (all p<0.05).

CONCLUSION

Kidney transplant patient and provider expectations differ in significant ways.

PRACTICE IMPLICATIONS

Identified areas of discordance may provide opportunities for patients and providers to better evaluate treatment option tradeoffs in post-transplant clinical interactions.

Catenins and their associated proteins in colorectal cancer

Colorectal cancer is the second most common cause of cancer mortality in the western world. Colorectal cancer has been well studied, and the genetic steps involved in the adenoma to carcinoma sequence have been well elucidated. The first genetic alteration, found in 85% of adenomas, are mutations in the adenomatous polyposis coli (APC) gene. However, the consequences of this and the exact function of APC in the colon is not fully understood. It has been suggested that APC could function through its regulation of beta-catenin, an ubiquitous cytoskeletal protein with multiple binding specificities resulting in diverse functions including cell growth, adhesion, and migration. Any change in these associations may play a role in colorectal cancer development and progression.

Prevalence of von Willebrand disease in children: a multiethnic study

OBJECTIVE

Von Willebrand disease (vWD) was thought to be a rare disorder until a recent survey reported a prevalence of 0.8% in an ethnically homogenous community in northern Italy. The purpose of this study was to determine the prevalence of vWD in an ethnically heterogenous population.

METHODS

Von Willebrand factor (vWF) was measured by the ristocetin cofactor method in 600 healthy children, aged 2 to 18 years, seen for routine school physical examinations in a three-state region. Personal and family bleeding symptoms were determined by questionnaire. The diagnosis of vWD required a personal history of bleeding symptoms, an abnormal vWF activity concentration, and a family history of at least one immediate family member with bleeding symptoms.

RESULTS

A total of 315 subjects were white, 212 were black, 16 were Hispanic, 10 were from other groups, and 47 were biracial. Eight subjects (four black, four white) met the criteria for vWD, for a prevalence of 1.3%. Seven subjects with vWD had blood group O (mean vWF = 32 U/dl; range, 10 to 42 U/dl), and one had blood group A (vWF = 41 U/dl). Children who had blood group O had significantly (p < 0.001) lower vWF activities (median, 83 U/dl, range, 43 to 162 U/dl) than those from non-O blood groups (median, 98 U/dl; range, 51 to 190 U/dl). There were no significant differences in vWF activity by ethnicity. The vWF activity was significantly (p < 0.02) greater for boys than girls in both blood groups.

CONCLUSION

Von Willebrand disease is the most common congenital hemostatic disorder; its high prevalence is not limited to one ethnic group.

Relative value of diagnostic studies for von Willebrand disease

Laboratory tests recommended to screen patients with mucosal bleeding for hemostatic disorders generally include determinations of prothrombin time, partial thromboplastin time, platelet count, and bleeding time. To determine the best tests to identify patients with von Willebrand disease (vWD), we reviewed the laboratory studies of 24 children with vWD and performed receiver operating characteristic analysis on the diagnostic studies. The vWD disease diagnostic tests included determinations of vWF activity (ristocetin cofactor activity), vWF factor antigen, and factor VIII procoagulant (VIII:c). The diagnosis of vWD required the presence of a personal and family history of bleeding symptoms and a documented abnormality of vWF activity or vWF antigen. vWF activity, vWF antigen, factor VIII:c and blood type were determined in 104 symptom-free children. There were no differences between patients and normal subjects for age, gender, or blood type. The bleeding time was abnormal in 43%, the partial thromboplastin time was abnormal in 25%, and either one or both were abnormal in 58% of the patients. The vWF activity, vWF antigen, and factor VIII:c were abnormal in 79%, 58%, and 33%, respectively. Receiver-operated-characteristic analysis showed the vWF activity to be superior to either the vWF antigen or factor VIII:c in establishing the diagnosis of vWD. The combination of the activity, bleeding time, and partial thromboplastin time successfully identified 92% of the patients as abnormal. Determination of vWF activity should be included routinely in the evaluation of hemostasis in children with symptomatic disease.
