Availability, affordability and stock-outs of commodities for the treatment of snakebite in Kenya.

BACKGROUND: Annually, about 2.7 million snakebite envenomings occur globally. Alongside antivenom, patients usually require additional care to treat envenoming symptoms and antivenom side effects. Efforts are underway to improve snakebite care, but evidence from the ground to inform this is scarce. This study, therefore, investigated the availability, affordability, and stock-outs of antivenom and commodities for supportive snakebite care in health facilities across Kenya. METHODOLOGY/PRINCIPAL FINDINGS: This study used an adaptation of the standardised World Health Organization (WHO)/Health Action International methodology. Data on commodity availability, prices and stock-outs were collected in July-August 2020 from public (n = 85), private (n = 36), and private not-for-profit (n = 12) facilities in Kenya. Stock-outs were measured retrospectively for a twelve-month period, enabling a comparison of a pre-COVID-19 period to stock-outs during COVID-19. Affordability was calculated using the wage of a lowest-paid government worker (LPGW) and the impoverishment approach. Accessibility was assessed combining the WHO availability target (≥80%) and LPGW affordability (<1 day's wage) measures. Overall availability of snakebite commodities was low (43.0%). Antivenom was available at 44.7% of public- and 19.4% of private facilities. Stock-outs of any snakebite commodity were common in the public- (18.6%) and private (11.7%) sectors, and had worsened during COVID-19 (10.6% versus 17.0% public sector, 8.4% versus 11.7% private sector). Affordability was not an issue in the public sector, while in the private sector the median cost of one vial of antivenom was 14.4 days' wage for an LPGW. Five commodities in the public sector and two in the private sector were deemed accessible. CONCLUSIONS: Access to snakebite care is problematic in Kenya and seemed to have worsened during COVID-19. To improve access, efforts should focus on ensuring availability at both lower- and higher-level facilities, and improving the supply chain to reduce stock-outs. Including antivenom into Universal Health Coverage benefits packages would further facilitate accessibility.

Health and economic burden estimates of snakebite management upon health facilities in three regions of southern Burkina Faso.

BACKGROUND: Snakebite has become better recognized as a significant cause of death and disability in Sub-Saharan Africa, but the health economic consequences to victims and health infrastructures serving them remain poorly understood. This information gap is important as it provides an evidence-base guiding national and international health policy decision making on the most cost-effective interventions to better manage snakebite. Here, we assessed hospital-based data to estimate the health economic burden of snakebite in three regions of Burkina Faso (Centre-Ouest, Hauts Bassins and Sud-Ouest). METHODOLOGY: Primary data of snakebite victims admitted to regional and district health facilities (eg, number of admissions, mortality, hospital bed days occupied) was collected in three regions over 17 months in 2013/14. The health burden of snakebite was assessed using Disability-Adjusted Life Years (DALYs) calculations based upon hospitalisation, mortality and disability data from admitted patients amongst other inputs from secondary sources (eg, populations, life-expectancy and age-weighting constants). An activity-based costing approach to determine the direct cost of snake envenoming included unit costs of clinical staff wages, antivenom, supportive care and equipment extracted from context-relevant literature. FINDINGS: The 10,165 snakebite victims admitted to hospital occupied 28,164 hospital bed days over 17 months. The annual rate of hospitalisation and mortality of admitted snakebite victims was 173 and 1.39/100,000 population, respectively. The estimated annual (i) DALYs lost was 2,153 (0.52/1,000) and (ii) cost to hospitals was USD 506,413 (USD 49/hospitalisation) in these three regions of Burkina Faso. These costs appeared to be influenced by the number of patients receiving antivenom (10.90% in total) in each area (highest in Sud-Ouest) and the type of health facility. CONCLUSION: The economic burden of snake envenoming is primarily shouldered by the rural health centres closest to snakebite victims-facilities that are typically least well equipped or resourced to manage this burden. Our study highlights the need for more research in other regions/countries to demonstrate the burden of snakebite and the socioeconomic benefits of its management. This evidence can guide the most cost-effective intervention from government and development partners to meet the snakebite-management needs of rural communities and their health centres.

Global systematic review of cost of illness and economic evaluation studies associated with snakebite.

BACKGROUND: Snakebite envenoming, a high priority Neglected Tropical Disease categorized by the World Health Organization (WHO), has been considered as a poverty-related disease that requires greater global awareness and collaboration to establish strategies that effectively decrease economic burdens. This prompts the need for a comprehensive review of the global literature that summarizes the global economic burden and a description of methodology details and their variation. This study aimed to systematically identify studies on cost of illness and economic evaluation associated with snakebites, summarize study findings, and evaluate their methods to provide recommendations for future studies. METHODS: We searched PubMed, EMBASE, Cochrane library, and Econlit for articles published from inception to 31 July 2019. Original articles reporting costs or full economic evaluation related with snakebites were included. The methods and reporting quality were assessed. Costs were presented in US dollars (US$) in 2018. RESULTS: Twenty-three cost of illness studies and three economic evaluation studies related to snakebites were included. Majority of studies (18/23, 78.26%) were conducted in Low- and Middle-income countries. Most cost of illness studies (82.61%) were done using hospital-based data of snakebite patients. While, four studies (17.39%) estimated costs of snakebites in communities. Five studies (21.74%) used societal perspective estimating both direct and indirect costs. Only one study (4.35%) undertook incidence-based approach to estimate lifetime costs. Only three studies (13.04%) estimated annual national economic burdens of snakebite which varied drastically from US$126 319 in Burkina Faso to US$13 802 550 in Sri Lanka. Quality of the cost of illness studies were varied and substantially under-reported. All three economic evaluation studies were cost-effectiveness analysis using decision tree model. Two of them assessed cost-effectiveness of having full access to antivenom and reported cost-effective findings. CONCLUSIONS: Economic burdens of snakebite were underestimated and not extensively studied. To accurately capture the economic burdens of snakebites at both the global and local level, hospital data should be collected along with community survey and economic burdens of snakebites should be estimated both in short-term and long-term period to incorporate the lifetime costs and productivity loss due to premature death, disability, and consequences of snakebites.

Paediatric snakebite envenoming: the world's most neglected 'Neglected Tropical Disease'?

Snakebite disproportionally affects children living in impoverished rural communities. The WHO has recently reinstated snakebites on its list of Neglected Tropical Diseases and launched a comprehensive Strategy for the Prevention and Control of Snakebite Envenoming. In the first of a two paper series, we describe the epidemiology, socioeconomic impact and key prevention strategies. We also explore current challenges and priorities including the production and distribution of safe and effective antivenom.

Management and cost of snakebite injuries at a teaching and referral hospital in Western Kenya.

Background: Data on the cost of snakebite injuries may inform key pillars of universal health coverage including proper planning, allocation, and utility of resources. This study evaluated the injuries, management, and costs resulting from snakebites at Jaramogi Oginga Odinga Teaching and Referral Hospital (JOOTRH) in Kenya.  Methods: In total, medical records of 127 snakebite victims attending JOOTRH between January 2011 and December 2016 were purposely selected and data on the age, gender, type of residence (urban or rural), part of the body bitten, time of bite, injuries, pre-hospital first aid, time to hospital, length of stay, treatment, and costs were collected. Regression analysis was used to predict the total indirect cost of snakebite injuries and p≤ 0.05 was considered significant. Mortality and loss of income of hospitalized victims were considered as direct costs. Results: It was found that 43 victims were 13-24 years of age, 64 were female, 94 were from rural areas, 92 were bitten on the lower limbs, 49 were bitten between 6.00 pm and midnight, 43 attempted pre-hospital first aid, and the median time to hospital was 4.5 hours. Antivenom, supportive therapy, antibiotics, antihistamines, corticosteroids, analgesics, and non-steroidal anti-inflammatory drugs were used. Cellulitis, compartment syndrome, gangrenous foot, psychiatric disorder, and death were the main complications. Most victims spent 1-5 days in hospital and the median cost of treating a snakebite was 2652 KES (~$26). Drugs, ward charges, and nursing procedures were the highest contributors to the total indirect cost. Victims hospitalized for 6-10 days and >10 days incurred 32% and 62% more costs, respectively, compared to those hospitalized for 1-5 days.  Conclusions: The longer snakebite victims are hospitalized, the higher the cost incurred. Continuous medical education on the correct management of snakebites should be encouraged to minimize complications that may increase hospital stays and costs incurred.

Snakebite in domestic animals: First global scoping review.

Snakebite is a Neglected Tropical Disease estimated to cause more than 100,000 human deaths and disable more than 400,000 victims each year. It primarily affects poor agricultural workers, farmers, and cattle herders living in rural areas of developing countries. It is thus an occupational disease. However, the impact of snakebite on these rural communities could be even higher if a One Health approach is taken to consider the direct impact on domestic animals and indirect impact on the livelihood of affected communities. To explore this hypothesis we developed the first scoping review to identify and characterize the global literature on snakebite in domestic animals. Three bibliographic databases (PubMed, Web of Science and Agricola) were searched using terms related to snake, snakebite and domestic animals for publications up to December 31st, 2016. Two independent reviewers screened publications applying inclusion/exclusion criteria to select relevant material. Relevant information was then extracted from the selected literature. The global literature on snakebite in domestic animals (n = 143 observational studies, reviews and letters) mainly represented North America, Europe and Australia (69%) with less information from Central and South America, Asia and Africa (31%). Observational studies (n = 119) mostly concerned pets (78%) and to a lesser extent livestock (22%). Thirty-four snake species were reported as responsible for bites in domestic animals. WHO's Medically Important Venomous Snakes were more frequently involved. The social-ecological determinants of snakebite were poorly documented but the reviewed literature suggested a strong seasonality and a diversity of habitat. Snakebite in animals caused neurotoxic, cytotoxic and hemotoxic envenomation syndromes similar to humans and death. Half of publications on envenomed livestock reported a fatality rate above 47%. There was no literature on the indirect impact of snakebite on livelihood caused by animal morbidity and mortality. The results of this scoping review suggest a high and under-reported burden in terms of mortality in animals and a potential economic impact of snakebite in terms of losses in livelihood of affected communities. However, major knowledge gaps with respect to impact of snakebite on livestock and livelihood were identified. Filling these gaps is necessary for a full understanding of the impact of snakebite and to raise scientific, political and public awareness on this neglected issue.

Childhood Drug and Non-Drug Poisoning in Nigeria: An Economic Appraisal.

BACKGROUND: The dearth of information on the economic cost of childhood poisoning in sub-Saharan Africa necessitated this study. OBJECTIVE: This study has investigated the prevalence of childhood drug and non-drug poisoning, treatment modalities and economic costs in Nigeria. METHOD: A retrospective study of childhood drug and non-drug poisoning cases from January 2007 to June 2014 in the University of Port Harcourt Teaching Hospital (UPTH), Port Harcourt, Nigeria was carried out. Medical records were analysed for demographic and aetiological characteristics of poisoned children (0-14 years of age), as well as fiscal impact of poisoning cases. FINDINGS: Of the 100 poisoned patients, 46% were male and 54% female, with female/male ratio of 1.17:1. Most of the children were under five years of age. Paracetamol, amitriptyline, chlorpromazine, ferrous sulphate, kerosene, organophosphates, carbon monoxide, snake bite, alcohol and rodenticides were involved in the poisoning. The average cost of poison management per patient was about $168, which is high given the economic status of Nigeria. CONCLUSION: Childhood poisoning is still a significant cause of morbidity among children in Nigeria and accounts for an appreciable amount of health spending, therefore preventive strategies should be considered.

The time is now: a call for action to translate recent momentum on tackling tropical snakebite into sustained benefit for victims.

Like the other WHO-listed Neglected Tropical Diseases (NTDs), snakebite primarily affects rural, impoverished tropical communities that lack adequate health resources. The annual 138 000 deaths and 400 000 disabilities suffered by these subsistence farming communities means that snakebite is an additional cause and consequence of tropical poverty. Unlike most of the NTDs, however, snakebite is a medical emergency, and requires rapid treatment in a hospital equipped with effective antivenom, beds and appropriately trained staff. The lack of such facilities in the remote areas most affected by snakebite, and the high treatment costs, explains why most victims, particularly in sub-Saharan Africa, consult traditional healers rather than seek hospital care. Whilst affordable, there is no evidence that traditional treatments are effective. The number of snakebite victims that die, unregistered, in the community is threefold higher than hospital-recorded deaths. After decades of inertia, WHO benefitted from advocacy interventions and the support of key agencies, including Médecins Sans Frontières, the Wellcome Trust, the Kofi Annan Foundation and the Global Snakebite Initiative, to recently institute transformative actions for reducing the public health burden of tropical snakebite. It is imperative that WHO and the other stakeholders now gain the support and investment of governments, research funders and donor agencies to ensure that this recent momentum for change is translated into sustained benefit to snakebite victims.

Venomous Snakebites in Canada: A National Review of Patient Epidemiology and Antivenom Usage.

INTRODUCTION: There are 3 pit viper species in Canada. Limited Canadian literature exists on the epidemiology of venomous snakebites and the treatment patterns with antivenom. This study described the epidemiology, the utilization of antivenom, and estimated expenditures due to forfeited antivenom for pit viper envenomations in Canada. METHODS: A retrospective review of the Health Canada Special Access Program records to generate descriptive statistics. Data are presented as mean±SD (range), as appropriate. RESULTS: The geographic distribution of Canadian pit viper species is presented. There were 99 envenomations reported in Canada from January 2009 to December 2015. The number of envenomations per year was 14±6 (6-21). CroFab and Antivipmyn are used in Canada to treat envenomations. The number of vials for patient treatment was 17±12 (3-66) and 16±9 (6-42) for CroFab and Antivipmyn, respectively. Antivenom stock usage for patient treatment varied across the country with provincial means reported for British Columbia (33%), Alberta (37%), Saskatchewan (27%), and Ontario (71%). The costs incurred secondary to forfeited stock where estimated as: $1,280,000 USD in British Columbia, $255,000 in Alberta, $60,000 in Saskatchewan, and $0 in Ontario. CONCLUSIONS: The absolute number of annual envenomations is small and the 3 Crotalinae species are limited to relatively narrow geographic areas in British Columbia, Alberta, Saskatchewan, and Ontario. The utilization of antivenom in the treatment of patients revealed that regions where the western and prairie rattlesnake reside forfeited a substantial amount of antivenom from 2009 to 2015. Organizations responsible for maintaining antivenom supplies on a provincial or regional level could use these data to guide antidote stocking and reduce costs.

Snakebite: An Exploratory Cost-Effectiveness Analysis of Adjunct Treatment Strategies.

The cost-effectiveness of the standard of care for snakebite treatment, antivenom, and supportive care has been established in various settings. In this study, based on data from South Indian private health-care providers, we address an additional question: "For what cost and effectiveness values would adding adjunct-based treatment strategies to the standard of care for venomous snakebites be cost-effective?" We modeled the cost and performance of potential interventions (e.g., pharmacologic or preventive) used adjunctively with antivenom and supportive care for the treatment of snakebite. Because these potential interventions are theoretical, we used a threshold cost-effectiveness approach to explore this forward-looking concept. We examined economic parameters at which these interventions could be cost-effective or even cost saving. A threshold analysis was used to examine the addition of new interventions to the standard of care. Incremental cost-effectiveness ratios were used to compare treatment strategies. One-way, scenario, and probabilistic sensitivity analyses were conducted to analyze parameter uncertainty and define cost and effectiveness thresholds. Our results suggest that even a 3% reduction in severe cases due to an adjunct strategy is likely to reduce the cost of overall treatment and have the greatest impact on cost-effectiveness. In this model, for example, an investment of $10 of intervention that reduces the incidence of severe cases by 3%, even without changing antivenom usage patterns, creates cost savings of $75 per individual. These findings illustrate the striking degree to which an adjunct intervention could improve patient outcomes and be cost-effective or even cost saving.

The neglected burden of snakebites in Cameroon: a review of the epidemiology, management and public health challenges.

OBJECTIVES: Snakebite is an underestimated medical and surgical emergency in developing countries responsible for a high disease burden. Optimal management of snake envenomation in these resource-limited settings is precluded by several public health challenges. In this review, we discuss the disease burden of snakebites in Cameroon and the public health challenges of its management in view of making recommendations essential for policy-making. MEDLINE, African Journals Online and Google Scholar were searched from January 1990 to February 2017 for studies addressing snakebite in Cameroon. Our search extended to include grey literature from book chapters, conference proceedings, theses and documents from organizations. RESULTS: Our results suggest that snakebites pose a significant health and economic burden in Cameroon. A composite of factors contributes to the challenge of managing snakebites in Cameroon and include: inadequate disease surveillance; poor health-seeking behaviours of patients; under-production and scarcity of anti-venom serum and the relatively high cost of anti-venom serum. There is an urgent need to revamp the current health policies through health education, promotion and building of sustainable health systems. Disease surveillance and management can be improved by providing refresher courses for healthcare providers and subsidization of the prices of anti-venom serum in pharmacies in the country.

The socio-economic burden of snakebite in Sri Lanka.

BACKGROUND: Snakebite is a major problem affecting the rural poor in many of the poorest countries in the tropics. However, the scale of the socio-economic burden has rarely been studied. We undertook a comprehensive assessment of the burden in Sri Lanka. METHODS: Data from a representative nation-wide community based household survey were used to estimate the number of bites and deaths nationally, and household and out of pocket costs were derived from household questionnaires. Health system costs were obtained from hospital cost accounting systems and estimates of antivenom usage. DALYs lost to snakebite were estimated using standard approaches using disability weights for poisoning. FINDINGS: 79% of victims suffered economic loss following a snakebite with a median out of pocket expenditure of $11.82 (IQR 2-28.57) and a median estimated loss of income of $28.57 and $33.21 for those in employment or self-employment, respectively. Family members also lost income to help care for patients. Estimated health system costs for Sri Lanka were $ 10,260,652 annually. The annual estimated total number of DALYS was 11,101 to 15,076 per year for envenoming following snakebite. INTERPRETATION: Snakebite places a considerable economic burden on the households of victims in Sri Lanka, despite a health system which is accessible and free at the point of care. The disability burden is also considerable, similar to that of meningitis or dengue, although the relatively low case fatality rate and limited physical sequelae following bites by Sri Lankan snakes means that this burden may be less than in countries on the African continent.

Resource utilization of pediatric patients exposed to venom.

BACKGROUND AND OBJECTIVE: Treating envenomation with antivenom is costly. Many patients being treated with antivenom are in observation status, a billing designation for patients considered to need care that is less resource-intensive, and less expensive, than inpatient care. Observation status is also associated with lower hospital reimbursements and higher patient cost-sharing. The goal of this study was to examine resource utilization for treatment of envenomation under observation and inpatient status, and to compare patients in observation status receiving antivenom with all other patients in observation status. METHODS: This was a retrospective study of patients with a primary diagnosis of toxic effect of venom seen during 2009 at 33 freestanding children's hospitals in the Pediatric Health Information System. Data on age, length of stay, adjusted costs (ratio cost to charges), ICU flags, and antivenom utilization were collected. Comparisons were conducted according to admission status (emergency department only, observation status, and inpatient status), and between patients in observation status receiving antivenom and patients in observation status with other diagnoses. RESULTS: A total of 2755 patients had a primary diagnosis of toxic effect of venom. Of the 335 hospitalized, either under observation (n = 124) or inpatient (n = 211) status, 107 (31.9%) received antivenom. Of those hospitalized patients receiving antivenom, 24 (22.4%) were designated as observation status. Costs were substantially higher for patients who received antivenom and were driven by pharmacy costs (mean cost: $17 665 for observation status, $20 503 for inpatient status). Mean costs for the 47 162 patients in observation status with other diagnoses were $3001 compared with $17 665 for observation-status patients who received antivenom. CONCLUSIONS: Treatment of envenomation with antivenom represents a high-cost outlier within observation-status hospitalizations. Observation status can have financial consequences for hospitals and patients.

Snakebite and its socio-economic impact on the rural population of Tamil Nadu, India.

BACKGROUND: Snakebite represents a significant health issue worldwide, affecting several million people each year with as many as 95,000 deaths. India is considered to be the country most affected, but much remains unknown about snakebite incidence in this country, its socio-economic impact and how snakebite management could be improved. METHODS/PRINCIPAL FINDINGS: We conducted a study within rural villages in Tamil Nadu, India, which combines a household survey (28,494 people) of snakebite incidence with a more detailed survey of victims in order to understand the health and socio-economic effects of the bite, the treatments obtained and their views about future improvements. Our survey suggests that snakebite incidence is higher than previously reported. 3.9% of those surveyed had suffered from snakebite and the number of deaths corresponds to 0.45% of the population. The socio-economic impact of this is very considerable in terms of the treatment costs and the long-term effects on the health and ability of survivors to work. To reduce this, the victims recommended improvements to the accessibility and affordability of antivenom treatment. CONCLUSIONS: Snakebite has a considerable and disproportionate impact on rural populations, particularly in South Asia. This study provides an incentive for researchers and the public to work together to reduce the incidence and improve the outcomes for snake bite victims and their families.

[Role of antivenoms in the treatment of snake envenomation]. / Place de l'immunothérapie dans le traitement actuel des envenimations ophidiennes.

The production of antivenoms, which were long deemed ineffective, dangerous and difficult to use, has improved dramatically. These antibodies (immunoglobulin G) are now fragmented, purified and controlled for their quality, leading to significantly better safety and facilitating their emergency use. Envenomation can result in various syndromes depending on the snake species: Viperidae venoms are highly inflammatory, hemorrhagic and necrotising, while Elapidae venoms can cause fatal respiratory paralysis. However, some Viperidae venoms can lead to asphyxiation similar to that observed in Elapidae envenomation while, conversely, Elapidae bites may be complicated by hemorrhage or necrosis, thus complicating etiologic diagnosis. Symptomatic treatment is complex, often insufficient, and frequently associated with adverse events. In contrast, antivenoms neutralize the venom and accelerate its clearance, thus providing an etiological treatment for envenomation, particularly in remote healthcare facilities in developing countries. Current formulations consist of polyvalent antivenoms covering most of the venomous species present in a specific region. The main limitation is their high cost, and the priority should be to develop new treatment strategies, including more affordable antivenoms, especially in developing countries where they are most needed.

Approach to the epidemiology of venomous bites in Spain.

This review presents a geographic distribution of the three autochthonous venomous snake species, which are the only viperids present in Spain, among the Iberian fauna: Vipera aspid; Vipera seoianei and Vipera latasti. This is followed by a detailed descriptive analysis of hospital care provided to patients admitted into hospital due to venomous bites, in the period from 1997 to 2009, using the data from the Spanish hospital discharge registry database. This analysis reveals that in Spain, during this period, 1649 cases were recorded, which means that hospital care was required for more than one hundred cases per year, of which nearly 1% of the cases resulted in death. Cases were recorded in all the Autonomous communities, but more than half (54, 14%) were concentrated in the following four regions: Cataluña, Castilla and León, Galicia and Andalucía. It is notable that this concentration of cases is not associated only with the population demographics of the community, but is also the result of the concurrence of very diverse factors of exposure including: habitat of venomous fauna, volume of rural population, farming activities, and practice of outdoor leisure activities. We also carried out a gross economic calculation for the use of hospital resources by each snakebite case requiring hospital care in Spain, which provided us with an approximate figure of 2000€ per case.

Safety and cost-effectiveness of a clinical protocol implemented to standardize the use of Crotalidae polyvalent immune Fab antivenom at an academic medical center.

STUDY OBJECTIVE: To evaluate the safety and cost-effectiveness of a clinical protocol adopted in June 2006 that included a comprehensive, objective assessment of snake bite envenomations and standardized the use of Crotalidae polyvalent immune Fab antivenom (FabAV). DESIGN: Retrospective medical record review. SETTING: Academic medical center that serves as the regional level I trauma center. PATIENTS: Seventy-five adults treated with FabAV for snake envenomations in the emergency department between June 1, 2003, and June 1, 2009; 30 patients received treatment according to the protocol (treatment group), and 45 patients received treatment that did not adhere to the protocol (control group). MEASUREMENTS AND MAIN RESULTS: Demographic and envenomation characteristics, as well as treatment details, were collected for all patients. In addition, information on quantity of FabAV vials required, length of hospital stay, and length of intensive care unit stay were compared between the treatment and control groups. In the treatment group, significantly fewer vials of FabAV were used (2.5 vs 4.727 vials, p=0.007). This decreased in usage correlated to a cost savings of approximately $2000/patient. Despite no significant difference in the severity of the envenomations between the two groups (p=0.379), the treatment group experienced a significantly shorter hospital length of stay (1.933 vs 2.791 days, p=0.030). No significant difference in the progression to fasciotomy or the development of allergic reactions was noted between the two groups. CONCLUSION: Use of a clinical protocol related to snake envenomations resulted in approximately two fewer vials of FabAV required for each patient. In addition, the treatment group experienced a shorter hospital length of stay without a corresponding increase in adverse events or envenomation progression. Data show that use of the protocol was cost-effective. The development of institution-specific multidisciplinary protocols regarding snake bite envenomations is recommended. Clinical pharmacists can play a vital role in the protocol development to ensure that optimal care is provided for this distinct patient population.
