Drug prescription patterns and their association with mortality and hospitalization duration in COVID-19 patients: insights from big data

Background

Different medication prescription patterns have been associated with varying course of disease and outcomes in COVID-19. Health claims data is a rich source of information on disease treatment and outcomes. We aimed to investigate drug prescription patterns and their association with mortality and hospitalization via insurance data for a relatively long period of the pandemic in Iran.

Methods

We retrieved hospitalized patients' data from Iran Health Insurance Organization (IHIO) spanning 26 months (2020-2022) nationwide. Included were patients with ICD-10 codes U07.1/U07.2 for confirmed/suspected COVID-19. A case was defined as a single hospitalization event for an individual patient. Multiple hospitalizations of a patient within a 30-day interval were aggregated into a single case, while hospitalizations with intervals exceeding 30 days were treated as independent cases. The Anatomical Therapeutic Chemical (ATC) was used for medications classification. The two main study outcomes were general and intensive care unit (ICU) hospitalization periods and mortality. Besides, various demographic and clinical associate factors were analyzed to derive the associations with medication prescription patterns and study outcomes using accelerated failure time (AFT) and logistic regression models.

Results

During the 26 months of the study period, 1,113,678 admissions with COVID-19 diagnosis at hospitals working in company with IHIO were recorded. 917,198 cases were detected from the database, among which 51.91% were females and 48.09% were males. Among the main groups of medications, antithrombotics (55.84% [95% CI: 55.74-55.94]), corticosteroids (54.14% [54.04-54.24]), and antibiotics (42.22% [42.12-42.32]) were the top used medications among cases with COVID-19. Investigation of the duration of hospitalization based on main medication groups showed antithrombotics (adjusted median ratio = 0.94 [0.94-0.95]) were significantly associated with shorter periods of overall hospitalization. Also, antithrombotics (adjusted odds ratio = 0.74 [95%CI, 0.73-0.76]), corticosteroids (0.97 [0.95-0.99]), antivirals (0.82 [0.80-0.83]), and ACE inhibitor/ARB (0.79 [0.77-0.80]) were significantly associated with lower mortality.

Conclusion

Over 2 years of investigation, antithrombotics, corticosteroids, and antibiotics were the top medications for hospitalized patients with COVID-19. Trends in medication prescription varied based on various factors across the country. Medication prescriptions could potentially significantly impact the trends of mortality and hospitalization during epidemics, thereby affecting both health and economic burdens.

'Inequalities in prevalence of hypertension, prehypertension, anti-hypertensive coverage, awareness, and effective treatment in 429 districts of Iran; a population-based STEPS 2016 small area spatial estimation model'

Purpose

While many studies have reported hypertension (HTN) and pre-hypertension (PHTN) in large geographic locations of Iran, information regarding district levels is missing. We aimed to examine inequalities in the prevalence of hypertension, prehypertension, anti-hypertensive coverage, awareness, and effective treatment of adults in districts of Iran.

Methods

We used 27,165 participants' data from the STEPS 2016 study in Iran. A small area estimation model was carried out to predict HTN in the 429 districts of Iran. HTN and PHTN were defined based on the American Heart Association Guideline. Awareness of being hypertensive, treatment coverage, and effective treatment were also estimated.

Results

HTN's crude prevalence was estimated to be in the range of 11.5-42.2% in districts. About PHTN, it was estimated to be 19.9-56.1%. Moreover, for awareness, treatment coverage, and effective treatment crude estimates ranged from 24.3 to 79.9%, 9.1 - 64.6%, and 19.5 - 68.3%, respectively, indicating inequalities in the distribution of aforementioned variables in 429 districts of Iran. Overall, better conditions were detected in central geographical locations and in females.

Conclusion

The inequality of increased blood pressure disorder and related measures are high in districts of Iran and pave the way for policymakers and local health organizers to use the findings of this study to address the inequity of existing resources and improve HTN control.

A Digital First Healthcare Approach to Managing Pandemics: A Scoping Review of Pandemic Self-Triage Tools

BACKGROUND

During the COVID-19 pandemic, many patient-facing digital self-triage tools were designed and deployed to alleviate demand for pandemic virus triage in hospitals and doctors' offices by providing a way for people to self-assess health status and get advice on whether to seek care. These tools, provided via websites, apps, or patient portals allow people to answer questions, e.g., about symptoms and contact history, and receive guidance to appropriate care, which might be self-care.

OBJECTIVE

The purpose of this scoping review was to explore the state of literature on digital self-triage tools that direct or advise care for adults during a pandemic, and to explore what has been learned about intended purpose, use, and quality of guidance, tool usability, impact on providers, and ability to forecast health outcomes or care demand.

METHODS

A literature search was conducted in July 2021 using MEDLINE, Embase, Scopus, PsycINFO, CINAHL and Cochrane databases. Using Covidence, 1227 titles and abstracts were screened by two researchers, with 83 reviewed via full text screening. 22 articles met inclusion criteria: they allowed adults to self-assess for pandemic virus and directed to care. Using Microsoft Excel, we extracted and charted the following data: authors, publication year and country, country the tool was used in, whether the tool was integrated into a healthcare system, research question/purpose, direction of care provided, and key findings.

RESULTS

All but two studies reported on tools developed since early 2020 during the COVID-19 pandemic. Studies reported on tools were developed in 17 countries. Direction of care advice included directing to an ER, seek urgent care, contact/see a doctor, be tested, or to stay at home/self-isolate. Only two studies evaluated tool usability. One used 52 use-cases to evaluate quality of advice by tools in four countries, finding advice varied, e.g., tools in the US and UK often advising staying home when clinical assessment was warranted, while tools in Japan and Singapore advised seeking care. No study demonstrated that the tools reduce demand on the health care system, although at least one suggests data can predict demand for care and data allows monitoring public health.

CONCLUSIONS

While self-triage tools developed and used around the world have similarities in directing to care (ER, physician, self-care), they also differ in important ways. Some collect data to predict healthcare demand. Some are for use when concerned about health status; others are intended to be used repeatedly by users to monitor public health. Quality of triage may vary. The high use of such tools during the COVID-19 pandemic suggests research is needed to assess and ensure quality of advice given by self-triage tools, and to assess intended or unintended consequences on public health and health care systems.

CLINICALTRIAL

Policy analysis of nutrition stewardship for prevention and control of Non-communicable diseases in Iran

BACKGROUND

Non- communicable diseases (NCDs) are the main cause of death, which lead to over 73% of death and 62% of DALYs globally. As an unhealthy diet is the leading behavioral risk factor of NCDs, in line with the national action plan for the prevention and control of NCD, this study explored the nutrition-related stewardship problems to reduce the burden of NCDs in Iran.

METHODS

This is a qualitative study. We interviewed 30 purposefully identified key informants, i.e., stakeholders, policymakers, and academics, from December 2018 to August 2019. All interviews were recorded and transcribed verbatim. We analyzed data using qualitative content analysis facilitated by MAXQDA 11 software.

RESULTS

Ample policies and laws were identified, most of which were not or partially implemented. Despite some plausible efforts, NCDs do not seem to be a top priority for high-level managers and decision-makers. Besides, the role of non-state actors, i.e., the private sector, is marginal in NCD's planning and management. Whereas the government, e.g., the Food and Drug Organization (FDO), is the biggest player. Worse still, many harmful products are advertised and easily distributed across the country.

CONCLUSION

Iran's government has created a noticeable roadmap to battle NCDs despite imposing many sanctions and related socioeconomic problems. Nevertheless, more interventions are needed to strengthen the stewardship of NCDs by various stakeholders. We recommend the government to monitor the implementation of policies and advertisement of harmful products to prioritize prevention and control of NCDs. In addition, we advocate employing the capacity of non-state actors to reduce the consumption of unhealthy food and the burden of NCDs across the country, ultimately.

Protocol Design for Surveillance of Risk Factors of Non-communicable Diseases During the COVID-19 Pandemic: An Experience from Iran STEPS Survey 2021

BACKGROUND

Regarding the growing burden of non-communicable diseases (NCDs) and exposure to their risk factors, and the continuous need for nationwide data, we aimed to develop the latest round of the STEPwise Approach to NCD Risk Factor Surveillance (STEPS) survey in 2021 in Iran, while the COVID-19 pandemic was still present.

METHODS

In addition to the three main steps of this survey, including questionnaires, physical measurements, and laboratory assessments, we adapted the survey with the situation caused by the COVID-19 pandemic, by adding to various aspects of study phases and changing some scientific and executive procedures in this round of STEPS survey in Iran. These changes were beyond the initial novelties embedded within the survey before the pandemic, by refining the study protocol benefiting from the previous experiences of the STEPS survey.

RESULTS

By amending the required changes, we could include a total of 27874 individuals in the first step of the survey. This number was 27745 and 18119 for the second and third steps. Comparing the preliminary results with the previous nationwide surveys, this study was highly representative on both national and provincial levels. Also, implementing the COVID-19 prevention and control strategies in all stages of survey led to the least infection transmission between the study investigators and participants.

CONCLUSION

The novel initiatives and developed strategies in this round of Iran STEPS survey provide a state-of-the-art protocol for national surveys in the presence of an overwhelming catastrophe like the COVID-19 pandemic and the triggered limitations and shortages of resources.

Health system performance in Iran: a systematic analysis for the Global Burden of Disease Study 2019

BACKGROUND

Better evaluation of existing health programmes, appropriate policy making against emerging health threats, and reducing inequalities in Iran rely on a comprehensive national and subnational breakdown of the burden of diseases, injuries, and risk factors.

METHODS

In this systematic analysis, we present the national and subnational estimates of the burden of disease in Iran using the Global Burden of Disease Study 2019. We report trends in demographics, all-cause and cause-specific mortality, as well as years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs) caused by major diseases and risk factors. A multi-intervention segmented-regression model was used to explore the overall impact of health sector changes and sanctions. For this analysis, we used a variety of sources and reports, including vital registration, census, and survey data to provide estimates of mortality and morbidity at the national and subnational level in Iran.

FINDINGS

Iran, which had 84·3 million inhabitants in 2019, had a life expectancy of 79·6 years (95% uncertainty interval 79·2-79·9) in female individuals and 76·1 (75·6-76·5) in male individuals, an increase compared with 1990. The number of DALYs remained stable and reached 19·8 million (17·3-22·6) in 2019, of which 78·1% were caused by non-communicable diseases (NCDs) compared with 43·0% in 1990. During the study period, age-standardised DALY rates and YLL rates decreased considerably; however, YLDs remained nearly constant. The share of age-standardised YLDs contributing to the DALY rate steadily increased to 44·5% by 2019. With regard to the DALY rates of different provinces, inequalities were decreasing. From 1990 to 2019, although the number of DALYs attributed to all risk factors decreased by 16·8%, deaths attributable to all risk factors substantially grew by 43·8%. The regression results revealed a significant negative association between sanctions and health status.

INTERPRETATION

The Iranian health-care system is encountering NCDs as its new challenge, which necessitates a coordinated multisectoral approach. Although the Iranian health-care system has been successful to some extent in controlling mortality, it has overlooked the burden of morbidity and need for rehabilitation. We did not capture alleviation of the burden of diseases in Iran following the 2004 and 2014 health sector reforms; however, the sanctions were associated with deaths of Iranians caused by NCDs.

A pilot study using financial transactions' spatial information to define high-risk neighborhoods and distribution pattern of COVID-19

BACKGROUND

Development of surveillance systems based on big data sources with spatial information is necessitated more than ever during this pandemic. Here, we present our pilot results of a new technique for the incorporation of spatial information of transactions and a vital registry of COVID-19 to evaluate the disease spread.

METHODS

We merged two databases of laboratory-confirmed national COVID-19 registry of Iran and financial transactions of point-of-sale devices from February to March 2020 as our training data sources. Spatial information was used for the visualization of maps and movements of sick individuals. We used the point-of-sale devices-related guild to check for the dynamics of financial transactions and effectiveness of quarantines.

FINDINGS

In the study period, 174,428 confirmed cases were in the COVID-19 registry with accompanying transactions information. In total, 13,924,982 financial transactions were performed by them, with a mean of 1.2 per day for each person. All guilds had a decreasing pattern of "risky" transactions except for grocery stores and pharmacies. The latter showed a decreasing pattern by impose of lockdowns. Different cities were the hotspot of disease transmission as many "high-risk" transactions were performed in them, among which Tehran (mainly its central neighborhoods) and southern cities of Lake Urmia predominated. Lockdowns indicated that the disease gradually became less transmissible.

INTERPRETATION

Financial transactions can be readily used for epidemics surveillance. Semi real-time results of such iterations can be informative for policy makers, guild owners, and general population to prepare safer commuting and merchandise spaces.

Dissection of non-pharmaceutical interventions implemented by Iran, South Korea, and Turkey in the fight against COVID-19 pandemic

Purpose

The novel coronavirus disease 2019 (COVID-19) has imposed a great global burden on public health. As one of the most affected countries, Iran has tackled emerging challenges in the path to overcoming the epidemic, with three peaks of the disease propagation as of February 19, 2020. To flatten the curve of the COVID-19 pandemic, most countries have implemented bundles of intrusive, sometimes extremely stringent non-pharmaceutical interventions (NPIs). In this communication, we have dissected the effectiveness of NPIs and compared the strategies implemented by Iran, Turkey, and South Korea to mitigate the disease’s spread.

Methods

We searched online databases via PubMed, Web of Knowledge, and Scopus. Titles/abstracts and full-texts were screened by two reviewers and discrepancies were resolved upon discussion.

Results

Our results provide insights into five domains: prevention, screening, in-patient and out-patient facilities, governance, and management of diabetes mellitus. Analysis of previous efforts put in place illustrates that by fostering efficient social distancing measures, increasing the capability to perform prompt polymerase chain reaction tests, applying smart contact tracing, and supplying adequate personal protective equipment, Turkey and South Korea have brought the epidemic sub-optimally under control.

Conclusion

From the perspective of policymakers, these achievements are of utmost importance given that attaining the aspirational goals in the management of the COVID-19 necessities a suitable adjustment of previous successful strategies. Hence, policymakers should be noticed that a suitable combination of NPIs is necessary to stem the disease’s propagation.

Biosensing surfaces and therapeutic biomaterials for the central nervous system in COVID-19

COVID-19 can affect the central nervous system (CNS) indirectly by inflammatory mechanisms and even directly enter the CNS. Thereby, COVID-19 can evoke a range of neurosensory conditions belonging to infectious, inflammatory, demyelinating, and degenerative classes. A broad range of non-specific options, including anti-viral agents and anti-inflammatory protocols, is available with varying therapeutic. Due to the high mortality and morbidity in COVID-19-related brain damage, some changes to these general protocols, however, are necessary for ensuring the delivery of therapeutic(s) to the specific components of the CNS to meet their specific requirements. The biomaterials approach permits crossing the blood-brain barrier (BBB) and drug delivery in a more accurate and sustained manner. Beyond the BBB, drugs can protect neural cells, stimulate endogenous stem cells, and induce plasticity more effectively. Biomaterials for cell delivery exist, providing an efficient tool to improve cell retention, survival, differentiation, and integration. This paper will review the potentials of the biomaterials approach for the damaged CNS in COVID-19. It mainly includes biomaterials for promoting synaptic plasticity and modulation of inflammation in the post-stroke brain, extracellular vesicles, exosomes, and conductive biomaterials to facilitate neural regeneration, and artificial nerve conduits for treatment of neuropathies. Also, biosensing surfaces applicable to the first sensory interface between the host and the virus that encourage the generation of accelerated anti-viral immunity theoretically offer hope in solving COVID-19.

Non-communicable diseases' risk factors in Iran; a review of the present status and action plans

Non-communicable Diseases (NCDs) are the leading causes of death globally, imposing a heavy burden on the healthcare systems, especially in low- and middle-income countries. Iran is a country in the Middle-East region with an aging population and changing disease risk factors, and now is facing NCDs as the major health problem of the country. Investigating NCDs' risk factors and tackling preventable ones is the main intervention to control their heavy burden. In this review, we discussed the most critical risk factors in Iran and the implemented programs and action plans to control them. A better knowledge on current status of risk factors and plans to tackle them, could help policymakers effectively rule policies and allocate resources to curb heavy burden of NCDs in Iran.
