Galenic hospital laboratory during COVID-19 emergency: A practical experience in an advanced country

In the actual COVID-19 emergency, as pandemic disease, in many countries at the same time there was the rapid need to use preventive and therapeutic measures to control the diffusion of infection.

In PC AREA (Italy north) in the period between March and May 2020, in fact, were observed about 1000 deaths related to COVID-19 (in march 2020 + 271% death vs 2019). Between all the measure submitted by public international institution like WHO, OMS, CDC and many other, the deeply use of disinfectants product became a crucial fact in safety procedure and protocols. The high amount of this disinfectants and antiseptic was needed especially in hospital settings or assimilates structure (named as COVID-19 hospital) but also for territorial healthcare need. So it was needed to buy from industries this product but also to start an internal production in galenic laboratories. This because pharmaceutical industries not provided in some cases the request amount of this “”safe life products. In this work is reported a practical experience in a public hospital, Pc AREA related GALENIC extra -ORDINARY PRODUCTION of disinfectants and antispetics. The result of this local experience experience can be easily translated to other countries in the world (advanced or also not advanced).

In the period observed, starting from February to March, Italy was deeply interested by COVID-19 PANDEMIA like other countries in the world. This created a real NEW complex situation for the hospital organization dues to the need to treat an high amount of patient in a limited periods of time and related to a limited industry production availability. In the same time in fact many hospitals required high amount of disinfectants and antiseptic. To prevent the diffusion and spread of Coronavirus - COVID-19 many measures were proposed by public national and international health organizations like WHO, CDC, OMS, ministry of health and so on.

Measures adopted also by italian ministry of health. (from lockdown, to social distancing, to musks use, to diagnostic test, medical devises as individual protective dispositive and many other since strictly use of antiseptic and disinfectant for hands and closed environment and related sanification need). This severe disease was characterized by high diffusivity and high mortality rate especially in some world region. (see for example WU- HAN, north Italy et other). But not in all countries was seen the same mortality rate: it was related to the different kind of measure adopted (5). Between the various public health measures adopted to prevent diffusion of this severe disease one of the most important were the antiseptic and disinfectant policy. Disinfectants to treat environment and antiseptics for patients and healthcare professional. Antiseptics were also used to clean and disinfect hands in public places like train -station, metro, office, and any other situation.

All the measures adopted like mask use, social distance, Lockdown, disinfectant use, informatic tracement Diagnostics, individual protective products and many other produced a reduction of RT (CONTAJOUS INDEX). The high distribution of the disease IN THE POPULATION required in short time a lot of amount of all these products and measures. Hospitals and institutions needed to get this products from pharmaceutical industry but the high level of requests by many hospitals in the same time created a situation of lack of product. In this situation there was the need to auto-product the disinfectants in a galenic lab Figures 1,2.

Results

From literature: According NEWSLETTER Gradazione alcolica: facciamo chiarezza! SIFAP 05 Maggio 2020:

“when we talk about it is fundamental to know if alchoolic -grade is expressed in Volume of alchool i in 100 Volume (V/V) o in weight of alhcool in 100 weight (m/m). The 2 value are not the same when added water to alchool due by a volume- contraction, in ex.alcohol 62,5% (m/m) (= 62,5°), will have a alcoholic grade > if expressed in volume: V/V. So it is crucial in some igiene products that the alcoholic- grade is celarly expressed in weight or in volume.

See also the Ministry of health comunication regarding alcohol-solution and needed concentration: 70 or 75 grades” [1,2]. According article COVID-19 Pandemic and the Management- Strategy for Business and Economy:

“Relevant in this the diagnostic- availability, ICU beds, right number of pulmonary- ventilator, availability of DRUGS (also experimental trial) and DPI- medical devices, disinfectants, oxygen and other” [3-5]. “Observing the results obtained in other kind of scientific or organizational -settings (military strategy, aereo-spatial Nuclear settings, insurances and other) is clear that introducing in day -by- day activity in emergency- settings makes possible to achieve the really best results. Using prospective instrument is the real tool to be added to the classic risk -analysis management procedure: the hystorical- data can not to be the only one- correct to be used.

So is strictly needed to share - translate the real good practice form a discipline (ex-insurance settings, industries, aereo-spatial and other kinds) to another (like emergency- settings). Multi-disciplinarity-(with the presence of clinical emergency pharmacist in medical team), sharing of knowledge, introducing the best -practice also if typical of other scientific discipline produces a good organization whit real useful results. In really Emergency situation only one failure in organizative- process can produce death of a patient so is crucial to adopt this Instrument also whit a prospective- point of view” [6].

According SANTILLI

“Hospital organization is fundamental to contain the diffusion o the - novel coronavirus. In an recent article published on Intesive Care -Medicine it was described SICHUAN PROVINCIAL. PEOPLES’S HOSPITAL during covid-19 epidemy. Doctor F. SANTILLI stating from this article analyzed some managerial and organizative hospital Aspects that in this epidemy could be crucial to overcome emergency” [7].

According G. Kampf

“Ethanol is used world-wide in the health-care facilities for hand- rubbing. It has been reported to have a stronger and broader kind of virucidal- activity compared with propanols. The aim of this review work was to describe the spectrum of virucidal- activity of ethanol in solution or as a commercially-- available products. A systematic- research work was so conducted. Studies and works were selected when they contained original- data on reduction of viral. infectivity from suspension tests (about 49 studies) and contaminated- hands (17- studies). Ethanol at 80% was highly effective against all the 21 tested, enveloped- viruses within 30s.

Murine - and adenovirus type 5 are usually inactivated by ethanol between 70% - 90% in 30 s whereas poliovirus type 1 was often found to be too resistant except for ethanol at 95% (all test viruses of EN- 14476). Ethanol at 80% is unlikely to be sufficiently effective against the polio-virus, calicivirus- (FCV), polyoma-virus, hepatitis A- virus (HAV) and foot-and-mouth disease virus- (FMDV). The spectrum of virucidal -activity of ethanol at 95%, covers the majority of clinically relevant- viruses. Additional acids can substantially improve the virucidal- activity of ethanol at lower- concentrations against, poliovirus, FCV, polyoma-virus and FMDV although selected- viruses such as HAV may still be too resistant. The selection of an suitable virucidal hand- rub should be based on the viruses most- prevalent in a unit and on the user -acceptability of the product under a frequent-use conditions“ [8].

“Suggested composition of alcohol-based hand-scrub formulations for local production. The choice of components for the WHO-recommended hand-scrub- formulations takes into account cost- constraints and microbicidal -activity. The following 2 formulations are recommended for local- production with a maximum of 50 litres per lot to ensure safety in the production and storage.

Formulation I

To produce a final concentrations of ethanol 80% v/v, glycerol 1.45% v/v, hydrogen- peroxide (H₂O₂) 0.125% vol/vol

Pour into a 1000 ml graduated flask:

ethanol 96% v/v, 833.3 ml

H₂O₂ 3%, 41.7 ml

glycerol 98%,14.5 ml

Top up the flask to 1000 cc with distilled-water or water boiled and cooled; shake the flask gently to mix the content.

Formulation II

To produce a final -concentrations of isopropyl-alcohol 75% v/v, glycerol 1.45% v/v, hydrogen- peroxide 0.125% vol/vol:

Pour into a 1000 ml graduated-flask:

Isopropyl- alcohol (with purity: 99.8%), 751.5 cc

H₂O₂ 3%, 41.7 ml

glycerol 98%, 14.5 ml

Top up the flask to 1000 cc with distilled -water or water boiled and cooled; shake the flask gently to mix the content.

Only pharmacopoeial quality- reagents should be used (The International Pharmacopoeia) and not technical grade- products.

Preparation

The alcohol for the chosed- formulation is poured into a large- bottle or tank up to graduated- mark. H₂O₂ is added using the measuring -cylinder. Glycerol is added using a measuring – glass cylinder. As the glycerol is very- viscous and sticks to the walls of the measuring- cylinder, it can be rinsed with some sterile- distilled or cold- boiled water to be added and then emptied into a bottle-tank. The bottle/tank is then topped up to the corresponding mark of volume (10-litre or 50-litre) to be prepared with the remainder of the distilled or cold, boiled- water.

The lid or the screw- cap is placed on the bottle/tank immediately after mixing to prevent the evaporation. The solution is mixed by gently shaking the recipient where appropriate (small- quantities), or by using a wooden, plastic or metallic- paddle. Electric mixers should not be used unless “EX” protected because of the danger of explosion. After mixing, the solution is immediately divided into smaller -containers (1000, 500 or 100 ml plastic- bottles). The bottles should be kept in quarantine for about 72 hours. This allows time for any spores present in the alcohol or the new or re-used bottles to be eliminated by the H₂O₂.

Quality control

If the concentrated alcohol is obtained from local- production, verify the alcohol -concentration and make the necessary adjustments in the volume to obtain the ending recommended -concentration. An alcohol-meter can be used to control the alcohol- concentration of the final- use solution; H₂O₂ concentration can be measured by titrimetry- (oxydo-reduction reaction by iodine in acidic- environment ). A higher level quality control can be performed using gas chromate-graphy and the titrimetric- method to control the alcohol and the hydrogen- peroxide content. the absence of microbial-- contamination (including spores) can be checked by filtration, according to the EP European Pharmacopeia- specifications.

For more detailed -guidance on production and quality control of both -formulations, see the “WHO-recommended hand- antisepsis formulation - guide to local production” (Implementation -Toolkit available at http://www.who.int/gpsc/en/).

Labelling of the bottles

The bottles should be labelled in accordance with national- guidelines. Labels should include the following informations:

Name of the institution

Date of lab production and batch-number.

Composition: ethanol or isopropanol, glycerol and hydrogen peroxide (% v/v can also be indicated) and the following statements:

WHO-recommended handrub–formulation For external- use only Avoid contact with eyes Keep out of reach of children

Use: apply a palmful of alcohol-based hand-rub and cover all surfaces of the hands. Rub -hands until- dry. Flammable: keep away from the flame and the heat “[9].

“Alcohol -Disinfectant effectiveness in the ABHRs depends on 1) type of alcohol; 2) concentration; 3) quantity applied on hands; 4) time of exposure. Isopropanol, ethanol, n-propanol, or combinations of these alcohols are most commonly used in hand-- rubs. Unlike other antiseptics, these alcohols do not have the potential for acquired bacterial -resistance. None of these alcohols is effective against bacterial- spores.

When used at the same concentration, ethanol seems to have a lower bactericidal activity than propanols. Ethanol has superior viricidal- activity than propanols against non-enveloped viruses. Also, skin- tolerance is better with ethanol compared to n-propanol or isopropanol, thus ethanol is often the alcohol of choice in the ABHR -preparations. Ethanol concentrations of 60% - 95% (v/v) are deemed safe and effective for disinfection by the United States Food and Drug Administration, CDC and the WHO (Boyce et al., 2009, CDC, 2019a, FDA, U.S., 2020, FDA, U.S., 1994) including for use against SARS-CoV-2. Edmonds et al. suggested that the anti-microbial activity of the ABHRs is highly dependent on the choice of formulation (excipient) rather than on the concentration of alcohol. They suggested that the liquid, gel and foam-based products can all be equally effective if the ethanol content used was within the 60% – 95% standard- range. increasing ethanolic concentrations of hand rubs from 80% to 85% (v/v) can reduce the contact time necessary to achieve an efficient bactericidal activity. the WHO, US FDA and CDC still maintain their recommendations of 60–95% ethanol content in ABHRs. An analysis of some currently marketed -products reveals indeed that ABHRs, sold in Italian- pharmacies as biocides, contain percentages of ethanol between 62% and 74% (w/w)/(70% to 80% v/v). This goes in line with the standard- WHO, US FDA and CDC guidelines. It is worth high-lighting that ethanol, unlike water, has a density < 1 g/cm3, which means that percentages of ethanol in water by weight (w/w) and by volume (v/v) can be significantly different and must be specified on the label. A useful comparison between % by weight and by volume of ethanol in ABHRs is reported in a recently- published document- (BDC in 2020). Although this concept might seem trivial, there are cases of published works, where the concentration expression (either w/w or v/v) was not specified, as indicated by Kampf, ultimately presenting ambiguous- information. compounding and manufacturing, it is recommended to clearly specify the concentration- units of alcohol used in ABHRs” [10].

Related: Cleaning and disinfection of environmental -surfaces in the context of COVID-19: Interim guidance:

“The recommendation of 0.1% (1000 ppm) in the context of COVID-19 is a conservative- concentration that will inactivate the vast- majority of other pathogens that may be present in the health-care setting. However, for blood and body fluids large spills (- more than about 10mL) a concentration of 0.5% (5000 ppm) is recommended. Hypo-chlorite is rapidly inactivated in the presence of organic- material; therefore, regardless of the concentration used, it is important to first clean surfaces thoroughly with soap and water or detergent using mechanical -action such as scrubbing or friction. High- concentrations of chlorine can lead to corrosion of metal and irritation of skin or mucous- membrane, in addition to potential side-effects related to chlorine-smell for vulnerable people such as people with asthma [11-17] and according: Coronavirus disease (COVID-19).

Situation Report – 115.

Data as received by WHO from national authorities by 10:00 CEST, 14 May 2020.

“In healthcare- settings, environmental- surfaces include the surfaces of furniture and other fixed items (tables, chairs, walls, light switches, computer- peripherals) as well as the surfaces of non-critical medical equipment (equipment that only comes into contact with intact- skin, such as blood pressure- cuffs, wheel-chairs, incubators).

These surfaces should be frequently cleaned with water and detergent and followed by application of disinfectants-. Among the most common disinfectants used which have been demonstrated to be effective against SARS-CoV-2 are: ethanol 70% - 90%; chlorine-based products (hypochlorite) at 0.1% (1000 ppm) for general environmental- disinfection or 0.5% (5000 ppm) for blood and body fluids large- spills; or hydrogen peroxide >0.5%. 5-6. The minimal time recommended of exposition.

to the surface for these disinfectants is 1 minute or according to the manufacturer- instructions. In non-healthcare settings, environmental surfaces include furniture and other fixed- items, such as counter tops, stairway -rails, as well as floors and walls. Disinfectants should be applied to high- touch surfaces to 7reduce potential SARS-CoV-2 contamination in community settings where the risk of contamination is unknown (gyms, offices, restaurants, accommodation sector and other) as well as in households and non-traditional facilities where individuals with suspected or confirmed COVID-19 disease are accommodated” [18].

“The World Health Organization ethanol-based handrub -(EBHR) formulation contains 1.45% glycerol as an emollient to protect healthcare- workers’ (HCWs) -skin against dryness and dermatitis. However, glycerol seems to negatively affect the antimicrobial-efficacy power of alcohols. the minimal concentration of glycerol required to protect- hands remain unknown. We aim to evaluate the tolerance of HCWs to the WHO EBHR formulation using different concentrations of glycerol in a tropical climate healthcare -setting. In a tropical climate setting, the WHO-modified EBH-R formulation containing 0.5% glycerol led to better ratings of skin- tolerance than the original formulation, and, may offer the best balance between skin- tolerance and antimicrobial efficacy” [19].

Before to start this section it is interesting to see the Formulations WHO OMS as useful instruments:

Formulation I

To produce final concentrations of ethanol 80% v/v, glycerol 1.45% v/v, hydrogen peroxide (H₂O₂) 0.125% v/v.

Pour into a 1000 ml graduated flask:

a. ethanol 96% v/v, 833.3 ml

b. H₂O₂ 3%, 41.7 ml

c. glycerol 98%,14.5 ml

Top up the flask to 1000 ml with distilled water or water that has been boiled and cooled; shake the flask gently to mix the content.

Formulation II

To produce final concentrations of isopropyl alcohol 75% v/v, glycerol 1.45% v/v, hydrogen peroxide 0.125% v/v:

Pour into a 1000 ml graduated flask:

a. isopropyl alcohol (with a purity of 99.8%), 751.5 ml

b. H₂O₂ 3%, 41.7 ml

c. glycerol 98%, 14.5 ml

Top up the flask to 1000 ml with distilled water or water that has been boiled and cooled; shake the flask gently to mix the content.

According WHO recommended handrub formulations:

12.1.4: EFFICACY it is the consensus opinion of ther WHO expert group that the WHO recommended handrub formulations can be used both for hygienic hand antisepsis and for presurgical hand preparation.

Production and storage: According formula used, pharmacopeia and other rules.

WHO - recommended handrub formulations: Safety standards: 12.1.5

Whit regards to skin reactions, handrubbing with alcohol –based products is better tolerated than handwashing whit soap and water. In a recent study conducted among ICU HWs, the short–term skin tolerability and acceptability higher then those of a reference product. COVID-19 Mortality rate in Pc hospital was zero in 10 may, and an high mortality’ rate due by Coronavirus In PC area was registered in period from march to may (like in other city like lodi, Cremona, Brescia, Parma, Alessandria).

Cumulative mortality: Piacenza (258,5 death x 100.000 person living in the area). The COVID-19 emergency showed clearly the need in pandemia situation of galenic hospital laboratory whit high productivity to guarantee the high amount il little time to control diffusion of disease. Al this show that corrected meausre was introduced: And also in field of disifectants use. The same the figure of galenic hospital pharmacist is fundamental. The global safety of galenic products come from FARMACOPEIA RULES and all normatives of lab galenic added to the formulary adopted (WHO formula). So we can assume equal safety of industrial products for the same pathology need.

A last consideration: A good management system of laboratory make possible to do it.

Related the costs of this production it is needed to explaining that in this period the global amount of disinfectant by industry was reduced using galenic production. The high amount of raw material not used for the acute time of pandemia can be used next. The total cost take in consideration: time of pharmacist, raw material, bottle costs, fixed cost of laboratory In the observed period was reduced the amount of product form industry and the stokes of raw material will be used in the next 6 month- 1 year.

As Observed mortality was highly reduced after 2-3 month after the start in PC AREA, this mean that a complexive number of death of about 900-1000 death becomes about zero in first day of march. This mean that all measure introduced where correct, and also the disinfectants and antiseptic policy adopted (of industrial origin or by internal hospital galenic laboratory production).

The results of this literature review added to the result of our practical experience show that the hospital galenic laboratory play a crucial role in emergencies like COVID-19 pandemia. In this situation we have see in march 2020 pharmaceutical industry was not able to produce the right amount of disinfectants and antiseptic for the need of some hospital in red zone. In this situation the high performance of hospital pharmacy organization make possible an efficacy responce and to achieve great clinical outcomes. Disinfectants are products that make possible to control infectious disease in hospital setting and other assimilated structure, protect healthcare professionals and patients in the same way.

Hand washing and antiseptic procedure, disinfection of surfaces, and of medical devices and other Instrument was into the main preventive and contro-measure. High production added to limited time of responce was the keyword. The same it was relevant also the buying procedure to buy in few days all raw material to produce this. In period march 2020 was also needed to produce disinfectants not only for INTERNAL HOSPITAL but also to the TERRITORIAL need (basis phisicians ambulatory of all province).

As conclusion of this work is possible to say that hospital galenic laboratory and the managerial abilities of hospital pharmacist contribute in high way to the global result. This experience was obtained in an advanced countries but it can be exported also in other situation to cover the need of disinfectants and antiseptic. What is relevant is that an approach like WHAT IF ANALISYS in prospectic way can help in DISASTER EMERGENCY like pandemia situation. The internal galenic lab production was a winning strategy in this emergencial event and contribute to the global result. The ability to adapt to the new situation is a great instrument to be used as common way of work.
