Investigating the tendency to use COVID-19 vaccine booster dose in Iran.

INTRODUCTION: Vaccine hesitancy is recognized as a significant public health threats, characterized by delays, refusals, or reluctance to accept vaccinations despite their availability. This study, aimed to investigate the willingness of Iranians to receive booster shots, refusal rate, and their preferred type of COVID-19 vaccine. MATERIALS AND METHODS: This cross-sectional study was conducted over a month from August 23 to September 22, 2022 using an online questionnaire distributed through WhatsApp and Telegram online communities. The questionnaire assessed participants' intent to accept COVID-19 booster vaccination and had no exclusion criteria. Data analysis involved using SPSS version 16.0, with t-tests and chi-square tests used to assess the bivariate association of continuous and categorical variables. A multivariate logistic regression model was built to examine the association between Health Belief Model (HBM) tenets and COVID-19 vaccination intent. The Hosmer Lemeshow Goodness of Fit statistic was used to assess the model's fit, with a p-value > 0.05 indicating a good fit. RESULTS: The survey was disseminated to 1041 adults and the findings revealed that 82.5% of participants expressed a desire to receive the booster dose. Participants who intended to be vaccinated were generally older (46.4 ± 10.9), mostly female (53.3%), single (78.9%), had received a flu vaccine (45.8%). The findings indicated that the HBM items, including perception of COVID-19 disease, perceived benefits of COVID-19 vaccines, COVID-19 safety/cost concerns, preference of COVID-19 vaccine alternatives, and prosocial norms for COVID-19 vaccination, received higher scores among individuals intending to be vaccinated compared to vaccine-hesitant individuals, with statistical significance (p < 0.05). However, the "COVID-19 risk-reduction habits" item had a higher score but did not reach statistical significance (p = 0.167). CONCLUSION: Factors such as lack of trust in the effectiveness of the vaccine, trust in specific vaccine manufacturers, and concerns about side effects of COVID-19 vaccine are among the most important factors. These findings have implications for national vaccination policies, emphasizing the need for policymakers in the health sector to address these factors as vital considerations to ensure the continuity of vaccination as one of the most important strategies for controlling the pandemic.

Estimating willingness to pay for diabetes complications.

BACKGROUND: Maximum willingness to pay (WTP) for a health benefit is connected to perceived value. This two-center study aims to analyse diabetic patients' WTP for obtaining a specific preventive treatment package to reduce severe diabetic complications and determine the factors that impact this value. METHODS: This cross-sectional research included 557 diabetics from two cities in Iran. The WTP for a preventative package minimising major diabetes complications (cardiovascular, renal, ocular, and diabetic foot) by 50% and 100% was tested using eight scenarios. The Diabetes Attitude Scoring Questionnaire (DAS-3) was used to examine patient attitudes toward diabetes. To determine WTP, a two-stage hurdle method was used. The level of significance was fixed to 0.05. RESULTS: Around 80% of 557 people interviewed (mean age 47.54) stated they wanted to pay for a diabetes prevention package. This package's WTP varied from 169.4 to $374.5 depending on the complication and degree of risk reduction. The largest value diabetic patients willing to pay for preventative packages that reduce the chance of blindness was reported, while the lowest cost was stated for the diabetic foot. WTP is influenced by wealth, location of study, marital status, and attitude toward special training, but not by the type of diabetes, inpatient or outpatient setting, or the complications diabetes patients are impacted by. Patients' diabetes attitudes were mainly negative. The score of the attitude of patients towards diabetes was generally suboptimal. CONCLUSION: Most diabetic patients were willing to pay for a preventive package and this value was not affected by the type of diabetes and its severity. Our research found that diabetic individuals are willing to pay the most for a preventative package that reduces the chance of blindness, and the least for diabetic foot care. WTP can help health officials allocate resources and manage budgets. The attitude of diabetic patients toward diabetes still needs further interventional research, however.
