Weighted Lottery to Equitably Allocate Scarce Supply of COVID-19 Monoclonal Antibody.

Importance: Equitable allocation of scarce medications is an important health policy goal. There are few data about attempts to achieve equitable allocation in the community setting. Objective: To describe the development and use of a weighted lottery to allocate a scarce supply of tixagevimab with cilgavimab as preexposure prophylaxis to COVID-19 for immunocompromised individuals and examine whether this promoted equitable allocation to disadvantaged populations. Design, Setting, and Participants: This quality improvement study analyzed a weighted lottery process from December 8, 2021, to February 23, 2022, that assigned twice the odds of drug allocation of 450 tixagevimab with cilgavimab doses to individuals residing in highly disadvantaged neighborhoods according to the US Area Deprivation Index (ADI) in a 35-hospital system in Pennsylvania, New York, and Maryland. In all, 10 834 individuals were eligible for the lottery. Weighted lottery results were compared with 10 000 simulated unweighted lotteries in the same cohort performed after drug allocation occurred. Main Outcomes: Proportion of individuals from disadvantaged neighborhoods and Black individuals who were allocated and received tixagevimab with cilgavimab. Results: Of the 10 834 eligible individuals, 1800 (16.6%) were from disadvantaged neighborhoods and 767 (7.1%) were Black. Mean (SD) age was 62.9 (18.8) years, and 5471 (50.5%) were women. A higher proportion of individuals from disadvantaged neighborhoods was allocated the drug in the ADI-weighted lottery compared with the unweighted lottery (29.1% vs 16.6%; P < .001). The proportion of Black individuals allocated the drug was greater in the weighted lottery (9.1% vs 7.1%; P < .001). Among the 450 individuals allocated tixagevimab with cilgavimab in the ADI-weighted lottery, similar proportions of individuals from disadvantaged neighborhoods accepted the allocation and received the drug compared with those from other neighborhoods (27.5% vs 27.9%; P = .93). However, Black individuals allocated the drug were less likely to receive it compared with White individuals (3 of 41 [7.3%] vs 118 of 402 [29.4%]; P = .003). Conclusions and Relevance: The findings of this quality improvement study suggest an ADI-weighted lottery process to allocate scarce resources is feasible in a large health system and resulted in more drug allocation to and receipt of drug by individuals who reside in disadvantaged neighborhoods. Although the ADI-weighted lottery also resulted in more drug allocation to Black individuals compared with an unweighted process, they were less likely to accept allocation and receive it compared with White individuals. Further strategies are needed to ensure that Black individuals receive scarce medications allocated.

A Novel Approach to Equitable Distribution of Scarce Therapeutics: Institutional Experience Implementing a Reserve System for Allocation of COVID-19 Monoclonal Antibodies.

BACKGROUND: In fall 2020, the Food and Drug Administration issued emergency use authorization for monoclonal antibody (mAb) therapies for outpatients with COVID-19. The Commonwealth of Massachusetts issued guidance outlining the use of a reserve system with a lottery for allocation of mAbs in the event of scarcity that would prioritize socially vulnerable patients for 20% of the infusion slots. The Mass General Brigham health system subsequently implemented such a reserve system. RESEARCH QUESTION: Can a reserve system be deployed successfully in a large health system in a way that promotes equitable access to mAb therapy among socially vulnerable patients with COVID-19? STUDY DESIGN AND METHODS: We conducted a retrospective review of the operation of the reserve system for allocation of mAb therapies to identify how referrals moved through the allocation process and what proportion of patients who were offered and received mAb therapies were socially vulnerable. RESULTS: Notwithstanding multiple operational challenges, the reserve system for allocation of mAb therapy worked as intended to enhance the number of socially vulnerable patients who were offered and received mAb therapy. A significantly higher proportion of patients offered mAb therapy were socially vulnerable (27.0%) than would have been the case if the infusion appointments had been allocated using a pure lottery system without a vulnerable reserve (19.8%), and a significantly higher proportion of patient who received infusions were socially vulnerable (25.3%) than would have been the case if the infusion appointments had been allocated using a pure lottery system (17.6%) INTERPRETATION: Our health system experience demonstrates that a reserve system with a lottery for tiebreaking is a viable way to distribute scarce therapeutics when enhancing access for certain groups is desirable.

Effect of Sugar-Free and Regular Toothpaste on Salivary Glucose and pH among Type 2 Diabetes- A Randomized Crossover Trial.

INTRODUCTION: Diabetes is one of the most prevalent diseases of mankind having general as well as oral health manifestations. Also, there is an increase of salivary glucose level in diabetic, inducing saccharolytic bacteria in saliva which can have adverse effects on oral tissue. AIM: To assess and compare the effect of sugar-free toothpaste on salivary glucose and pH among Type 2 diabetic and non-diabetic individuals. MATERIALS AND METHODS: A randomized controlled-crossover study was carried out on 30 Type 2 diabetic (Group A) and 45 non-diabetic (Group B) subjects. In first half of study, subjects in Group A and Group B were intervened with sugar-free and regular toothpaste respectively. Salivary glucose and pH was assessed before and after brushing at interval of one week for a period of four weeks. In second half, toothpastes were switched over between the groups, after sufficient washout period. Salivary glucose and pH were assessed again in the same manner for both the groups. The data was subjected to paired t-test and unpaired t-test for intragroup and intergroup comparison respectively. RESULTS: Salivary glucose level was significantly reduced and salivary pH was increased significantly (p<0.001) in both groups with sugar free toothpaste when compared to regular toothpaste. CONCLUSION: Sugar free toothpaste showed beneficial effect on salivary glucose level and salivary pH level on diabetes and non-diabetes population.
