Abstract The pandemic of COVID-19 has become one of the greatest threats to human health, causing severe disruptions in the global supply chain, and compromising health care delivery worldwide. Although government authorities sought to contain the spread of SARS-CoV-2, the virus that causes COVID-19, by restricting travel and in-person activities, failure to deploy time-sensitive strategies in ramping-up of critical resource production exacerbated the outbreak. Here, we analyze the interactive effects of supply chain disruption and infectious disease dynamics using coupled production and disease networks built on global data. We find that time-sensitive containment strategies could be created to balance objectives in pandemic control and economic losses, leading to a spatiotemporal separation of infection peaks that alleviate the societal impact of the disease. A lean resource allocation strategy is discovered that effectively counteracts the positive feedback between transmission and production such that stockpiles of health care resources may be manufactured and distributed to limit future shortage and disease. The study highlights the importance of cross-sectoral coordination and region-wise collaboration to optimally contain a pandemic while accounting for production.

The Impact

AbstractThe pandemic of COVID-19 has become one of the greatest threats to human health, causing severe disruptions in the global supply chain, and compromising health care delivery worldwide. Although government authorities sought to contain the spread of SARS-CoV-2, by restricting travel and in-person activities, failure to deploy time-sensitive strategies in ramping-up of critical resource production exacerbated the outbreak. Here, we developed a mathematical model to analyze the effects of the interaction between supply chain disruption and infectious disease dynamics using coupled production and disease networks built on global data. Analysis of the supply chain model suggests that time-sensitive containment strategies could be created to balance objectives in pandemic control and economic losses, leading to a spatiotemporal separation of infection peaks that alleviates the societal impact of the disease. A lean resource allocation strategy can reduce the impact of supply chain shortages from 11.91 to 1.11% in North America. Our model highlights the importance of cross-sectoral coordination and region-wise collaboration to optimally contain a pandemic and provides a framework that could advance the containment and model-based decision making for future pandemics.

Total Charges

Along the health care supply chain, cost and quality measures are vital in the decision-making process for treatment and care delivery. This study applies statistical significance to a hypothesis about cost effectiveness of patients’ total charges by health insurance providers for different heart conditions. A retrospective, observational analysis of data is collected from an urban hospital in the Southeastern United States. Using the Agency for Healthcare Research and Quality (AHRQ) database, diagnoses are selected for further analysis based on their prevalence in the general population. The numbers of procedures as well as the patient’s length of stay in the hospital are significantly higher among the Medicare population. However, results indicate that although Medicaid and Medicare have significantly higher ordinary average total charges than the private counterparts, the difference is negligible when comparing means adjusted to remove covariate influence. One implication is that if private insurers were to insure the same types of high risk patients as Medicare and Medicaid the average total charges of a visit would be comparable between providers. These results also suggest that to enhance cost saving measures in government funded insurance programs, the clinical pathways need to be adapted to reduce length of stay and number of procedures per visit.

Optimum Manner

Drug supply shortages globally make hospitals vulnerable. It effects service delivery and patient satisfaction apart from endangering lives. Further, drug sourcing to ensure supply to satisfy patients' needs is a strategic priority for any health care system in any country. Katutura hospital and Namibia is no exception. However, frequent drug shortages have created difficulty in ensuring patients get prescribed medication. Adopting a descriptive research design, pharmacists, and nurses were surveyed and 22 questionnaires were distributed out of which 21 (95%) responded in full. The main objective of this study was to identify the causes of the drug supply shortage from a supply chain perspective and suggest strategies to deal with the shortage in an optimum manner. The findings reveal supply chain disruption, management inefficiencies, are inadequate inventory management are some of the main causes for drug supply shortage resulting in difficulties and inefficiencies for proper drug delivery and supply.

Biomedical Waste

Effective and efficient biomedical wastes management is vital in the health care delivery system, safe environment and public health could possibly be achieved through the standard practices of the biomedical waste procedures with safety measures in place. The study was aimed to evaluate the practices and the level of awareness of health workers towards biomedical waste management in selected hospitals in Abuja. Data were collected by structured questionnaire and on- the-spot observation. Three private and three public hospitals that provided health care services in Abuja were surveyed. Descriptive and inferential statistical analysis were used in the analysis of the data. Chi-square (χ2) test was used to determine the level of significance set at p<0.05. The male health workers were 220 (55.00%) and the female were 180 (45.00%) in the survey. The nurses were the highest number of respondents in the study with frequency percentage of 117(28.75%) followed by the laboratory scientists 96 (24.00%), Pharmacists 71 (17.75%, Doctors 64(16.00%) and other health care workers 54 (13.50%). The practices of handling biomedical waste among health workers was a significant factor of biomedical waste management (p<0.05). The awareness on safety measures among health workers was a significant factor of biomedical waste management (p<0.05). Improvement in the aspects of training retraining of health workers will go a long way to fill the lapses in the biomedical waste’s management practices. Government should establish policies and laws to enforce strict compliance in accordance with WHO stipulations.
