Pharmacovigilance trainings: four basic considerations for establishment of training environment

Pharmacovigilance trainings: You love it or hate it, but can not ignore it 

Yes, you read it right! You love it or hate it but can not ignore it. If someone says WHY? The reason is quite clear and simple..it is regulatory requirement👮

Need to understand further refer my previous blog "Pharmacovigilance Trainings: a succinct summary from GVP Modules"

First thing we need to understand that pharmacovigilance trainings fall under pharmacovigilance quality systems (GVP Module I – Pharmacovigilance systems and their quality systems) (consider it serious as other pharmacovigilance process).  

Below mention four basic considerations will save you from future observation from audit (internal/external) or regulatory inspection

Let's discuss some of them one by one - 

1. All person involved in pharmacovigilance training should receive initial and follow-up continuing trainings whether new or existing employee. 

New Employee: - New employee should undergo all necessary trainings according to job role and training plan. 

Let's understand this with possible trainings case processor/data entry role

  • Pharmacovigilance (PV) Trainings - Introduction of MedDRA and MedDRA coding, MedDRA  Term Selection: Points to Consider, Module VI – Collection, management and submission of reports of suspected adverse reactions to medicinal products, ICH Guidelines (ICH E2A, ICH E2B and E2D at least)
  • Quality Perspective Trainings: GVP Module I- Pharmacovigilance systems and their quality system, Case level quality and Field level quality parameters or fields from the database, Organizational quality policy
  • Audit and Inspection Specific Trainings: Module-III - Pharmacovigilance Inspections and Module IV- Pharmacovigilance Audits
  • MAH/Organization specific controlled documents Trainings: Standard Operating Procedures (SOP), Work Instructions (WI), Job-Aid, Policy, Any other document deemed important by respective Marketing Authorization Holder (MAH) or organization.
  • Human Resource Trainings (not direct relation with pharmacovigilance but essential to understand organization DNA and work environment)
  • Database Trainings
  • Trainings assessment methodology 

Existing Employee: 

  • Training upon new introduction of controlled documents (SOP/WI/Job-Aid/Policy)
  • Change or update in regulatory guidelines
  • Change in PV database functionalities 
  • Changes/Updates in Safety Data Exchange Agreements (SDEA)- MAH, Distributors and Manufacture type
  • Trainings related to outcome of audit or findings of regulatory inspection
  • Quality related re-trainings
  • Periodic refresher trainings
2. Training plan and Training records- documented evidences that  proves person undergone sufficient relevant trainings which demonstrate competency for assigned job role

3.  Training of Non-Pharmacovigilance Persons - Any person who directly or indirectly involved in receipt of any type of safety information (which includes company's sales representative, receptionist, persons handling company's social media, HR & Admin, etc.)

4. If any organization uses training software or portal then relevant user manual or work instruction, audit trail, system generated outputs including compliance reports, user access management process, training allocation handling process is advisable to have documented.

In short, all staff should be appropriately trained with evidences of their training (theoretical and practical) in ongoing manner.

Pharmacovigilance Trainings: a succinct summary from GVP Modules

Training is integral part of success whether it is in sports or event any work. It is very much essential for establishment of quality systems. This is utmost true for quality systems in pharmacovigilance any setting like marketing authorization holders, competent authorities of Member States and the Agency.

Let's see what GVP Module I – Pharmacovigilance systems and their quality systems and other GVP Modules states about training in achieving quality systems in pharmacovigilance. 

  1. A sufficient number of competent and appropriately qualified and trained personnel shall be available for the performance of pharmacovigilance activities [IR Art 10(1), Art 14(1)].
  2. Ensuring that sufficient resource available and training provided.
  3. All personnel involved in the performance of pharmacovigilance activities shall receive initial and continued training [IR Art 10(3), Art 14(2)]. For marketing authorization holders, this training shall relate to the roles and responsibilities of the personnel [IR Art 10(3)]. 
  4. The organization shall keep training plans and records for documenting, maintaining and developing the competences of personnel [IR Art 10(3), Art 14(2)].
  5. Training plans should be based on training needs assessment and should be subject to monitoring.
  6. All staff members of the organization should receive and be able to seek information about what to do if they become aware of a safety concern.
  7. There should be a process in place within the organization to check that training results in the appropriate levels of understanding and conduct of pharmacovigilance activities for the assigned tasks and responsibilities
  8. Adequate training should also be considered by the organization for those staff members to whom no specific pharmacovigilance tasks and responsibilities have been assigned but whose activities may have an impact on the pharmacovigilance system or the conduct of pharmacovigilance. Such activities include but are not limited to those related to clinical trials, technical product complaints, medical information, terminologies, sales and marketing, regulatory affairs, legal affairs and audits.
  9. Appropriate instructions on the processes to be used in case of urgency, including business continuity , shall be provided by the organization to their personnel [IR Art 10(4), Art 14(3)].
  10.  Training should support continuous improvement of relevant skills, the application of scientific progress and professional development
  11. The quality systems shall be documented by training plan and records
  12. Training plans and records shall be kept and made available for audit and inspection [IR Art 10(3), Art 14(2)].
  13. In scenario where QPPV has not completed basic medical training in accordance with Article 24 of Directive 2005/36/EC, the marketing authorization holder shall ensure that the QPPV is assisted by a medically trained person (i.e. in accordance with Article 24 of Directive 2005/36/EC) and this assistance shall be duly documented [IR Art 10(1)].
  14. The applicant or marketing authorization holder should provide the QPPV with training in relation to its pharmacovigilance system. Consideration should be given to additional training, as needed, of the QPPV in the medicinal products covered by the pharmacovigilance system.
Module II – Pharmacovigilance system master file (Rev 2)
  1. Staff should be appropriately trained for performing pharmacovigilance related activities and this includes not only staff within pharmacovigilance departments but also any individual that may receive safety reports.
  2. A summary description of the training concept, including a reference to the location training files
Module III – Pharmacovigilance inspections (Rev 1)
  1. Quality and adequacy of training, qualification and experience of staff during routine pharmacovigilance inspection
  2. Training and experience should be documented individually and evaluated according to the requirements of the applicable quality system of the concerned competent authority.
Module IV – Pharmacovigilance audits (Rev 1)  
  1. Under strategic level audit planning risk to availability of adequately trained and experienced pharmacovigilance staff (e.g. due to significant turn-over of staff, deficiencies in training processes, re-organisation, increase in volumes of work) also being considered.
  2. The proficiency of audit team members requires a combination of education, work experience and training
Module VI – Collection, management and submission of reports of suspected adverse reactions to medicinal products (Rev 2)

  1. Staff directly performing pharmacovigilance activities should be appropriately trained in applicable pharmacovigilance legislation and guidelines, in addition to specific training in report processing activities for which they are responsible and/or undertake
  2. Data entry staff should be instructed in the use of the appropriate standards and terminologies, and their proficiency confirmed for EU guidance on training of personnel for pharmacovigilance
  3.  Other personnel who may receive or process safety reports (e.g. clinical development, sales, medical information, legal, quality control) should be trained in adverse events/reactions collection and submission to the pharmacovigilance department in accordance with internal policies and procedures.
  4. It is recognised that literature search results are a surrogate for the actual article. Therefore, it is expected that the person reviewing the results of a search is trained to identify the articles of relevance. This may be an information professional trained in pharmacovigilance or a pharmacovigilance professional with knowledge of the database used. 
Module VII – Periodic safety update report (Rev 1)
  1. For all organizations, it is the responsibility of the person responsible for the pharmacovigilance system to ensure that the personnel, including pharmacovigilance, medical and quality personnel involved in the preparation, review, quality control, submission and assessment of PSURs are adequately qualified, experienced and trained according to the applicable guidelines (e.g. ICH E2C(R2) and this GVP Module VII). 
  2. When appropriate, specific training for the different processes, tasks and responsibilities relating to the PSUR should be in place. 
  3. Training to update knowledge and skills should also take place as necessary. 
  4. Training should cover legislation, guidelines, scientific evaluation and written procedures related to the PSUR process. 
  5. Training records should demonstrate that the relevant training was delivered prior to performing PSUR-related activities. 
Explanatory Note to GVP Module VII, Revision 3

Marketing authorisation holders (MAHs) may consider training on ICH E2C (R2) guideline and the ICH E2C Questions and Answers (Q&A) developed by the ICH-E2C (R2) Implementation Working Group (IWG).

Module VIII – Post-authorisation safety studies (Rev 3) 
  1. For studies that are funded by a marketing authorization holder, including studies developed, conducted or analysed fully or partially by investigators who are not employees of the marketing authorization holder, the marketing authorization holder should ensure that the investigators are qualified by education, training and experience to perform their tasks.
Module IX – Signal management (Rev 1)

  1.  Each organization should ensure that staff members are specifically trained in signal management activities in accordance with their roles and responsibilities
  2. Relevant staff members within competent authorities and marketing authorization holders should familiarise themselves with the guidance and training materials on EudraVigilance outputs made available online by the Agency and the training should be documented in line with the organization's internal procedures
In short, each individual or team should be properly qualified and trained to perform designated pharmacovigilance activities (any). There should be provision on initial and ongoing training along with training plan and training documentation. Other personnel who may receive safety information (e.g. clinical development, sales, medical information, legal, quality control) should be trained in adverse events/reactions collection and submission to the pharmacovigilance department in accordance with internal policies and procedures. This also apply to members from health authority and investigators involved in clinical trials and safety studies.

PHARMACOVIGILANCE TRAINING Is Crucial To Your Business. Learn Why!



Pharmacovigilance Training is Crucial to Business.


Yes! You have read it right.


Pharmacovigilance training is crucial for your business better than any other PV activity. Training is one of the crucial components for running the business however, it gets neglected many times. Pharmaceutical companies or Contract Research Organizations (CRO) are set up pharmacovigilance training departments and develop some training modules for their employees and give self consolation that they have set up PV training as per recommendation from the Good Pharmacovigilance Practice modules (GVP).


GVP Module I – Pharmacovigilance systems and their quality systems emphasize the importance of PV training by mentioning a few of the following recommendations-
  1. A sufficient number of competent and appropriately qualified and trained personnel shall be available for the performance of pharmacovigilance activities [IR Art 10(1), Art 14(1)].
  2. The organization should ensure that adequate resources are available and that training is provided.
  3. All personnel involved in the performance of pharmacovigilance activities shall receive initial and continued training [IR Art 10(3), Art 14(2)].
  4. For marketing authorization holders, this training shall relate to the roles and responsibilities of the personnel [IR Art 10(3)].
  5. Training plans should be based on training needs assessment and should be subject to monitoring.
  6. The organization shall keep training plans and records for documenting, maintaining, and developing the competencies of personnel [IR Art 10(3), Art 14(2)].
  7. Training plans and records shall be kept and made available for audit and inspection [IR Art 10(3), Art 14(2)].
  8. The applicant or marketing authorization holder should provide the QPPV with training in relation to its pharmacovigilance system, which is appropriate for the role prior to the QPPV taking up the position and which is appropriately documented
  9. Where the QPPV has not completed basic medical training in accordance with Article 24 of Directive 2005/36/EC, the marketing authorization holder shall ensure that the QPPV is assisted by a medically trained person (i.e. in accordance with Article 24 of Directive 2005/36/EC) and this assistance shall be duly documented [IR Art 10(1)].
  10. Adequate training should also be considered by the organization for those staff members to whom no specific pharmacovigilance tasks and responsibilities. 
In the majority of the organizations, the skeleton structure of training are as follow- 
  • Induction Training - Self-explanatory- Given at the time of induction
  • Ongoing Training - Issue of new controlled documents (i.e. SOP, Work Instruction (WI), Job-Aid) or Revision of existing controlled documents
  • Refresher Training - Periodic Training for controlled documents
  • Adhoc Training - As an when it is needed. Publication of new regulatory guidelines or training imparted as a part of a regulatory inspection or findings from audit or inspection.

Provision of pharmacovigilance activity is one of the mandatory requirements to obtain marketing authorization in certain countries. After getting marketing authorization, an organization should continue to monitor the benefit-risk profile of the molecule. Trained pharmacovigilance professionals are required to carry out PV activity.

According to GVP, training shall relate to the roles and responsibilities of the personnel. However, many organizations failed to identify training requirements according to job-role which might lead to delay or failure in PV deliverables in terms of quality and quantity. 

Let understand this with the ICSR example- 

Let us assume if any organization processed 220 Individual Case Safety Report (ICSR)/cases per month by 3 persons (Data Entry, Quality Review, and Medical Review). We can say that 10 cases are processed per day with 48 mins of average processing time (considering 480mins per day work and 22 working days). 

If we identify training gaps and planed targeted training and can able to reduce 20% (9.6 mins) of single case processing time. Then we can have 38.4 mins of average processing time and the same team can contribute 12.5 cases per day (instead of the previous 10 cases). That means we now have revised productivity of 275 cases per month i.e. ~ 25% rise compared to the previous month. 

If the same example we go for higher processing time then productivity falls significantly.

If we extrapolate this with the large numbers then it significantly impacts our work efficiency and that leads to business. 

This can be applied to the quality part also...In a general sense, data entry performed by a trained data entry person has a low or minimal error which leads to completion of quality review and medical review in a shorter time and ultimately productivity boost up and business also.

The training concept can be applied to other pharmacovigilance functions like literature review, aggregate reports, signal detection activities, etc. 

Once the system improves, then we can have no or minor findings in audits and inspections. Ultimately, It is a WIN-WIN situation for any organization by strengthening training culture and periodic assessment of the effectiveness of training. 

Signing Off. 

Thank you.😊

Learnings from LinkedIn Learning Course "Customer Service Foundations" by Jeff Toister

Customer service is the support you offer to your customers, both existing and prospective customers.

Customer Service Foundations course is divided in to four parts-

  • 1    Outstanding Customer Service
  • 2.   Build Rapport
  • 3.  Exceed Expectations
  • 4.  Solve Problems

 1.      Outstanding Customer Service

There are three types of customer services-

·         Good Customer Service

·         Outstanding Customer Service

·         Poor Customer Service

Good Service occurs when customers’ expectations are met. Outstanding customer services service that exceeds your customers' expectation. The challenge with good service is that it is not very memorable. Poor Customer Service occurs when the experience is worse than the customer expected.

One of the unique challenges of the customer services that your customer decide how they feel, some said they feel great even though you haven't done anything special. On the contrary, they feel anger even after you try your hardest pushed off, so the best thing is to treat each customer as an individual and try to understand their unique needs. Customers often look at the people who serve them as a representative of the entire organization.

Customer Service

Customer Expectations

Memorable to Customer

Good Customer Service

  Meet

Not Memorable

Outstanding Customer Service

  Exceed

Highly Memorable

Poor Customer Service

  Not Meet (Worst)

Highly Memorable

 Determine the value of outstanding customer service

Customer service is not easy, but one can choose extra effort to be outstanding. People go above and beyond because they get something out of it. Happy customers are easier to serve. There is a positive impact on co-workers, increased profits, retained customers, and positive word of mouth from customers who refers others to your organizations.

Identify your customers

We are dealing with different types of customers. It is helpful to identify their basic need. A customer is anyone you serve- clients, contractors, co-workers and even vendors (Internal and external customers)

Create customer service vision

Create your personal vision statement. Customer service vision refers to the way you want your customer to feel when you serve them. We can’t make every customer happy, but a personal service vision can inspire us to try. The visualization on positive feedback can helps you stay focused on providing outstanding service throughout each and every day.       

2.      Build Rapport

Building rapport with people you serve is one of the most essential skills in customer service. This creates a personal connection and hopefully getting them to know and like you. Rapport helps in breakdown barriers and makes everyone feels more comfortable. The customer tends to be more loyal when you established rapport and likely to forgive your mistakes.

A good greeting can immediately put a customer an ease and help you quickly developed a rapport. One of the most effective techniques is communicating a positive message with your tone of voice and your body language.

3.      Exceed Expectations

It is critical to learn each customer’s need, so you know how they want to be served. By doing this, you can avoid falling short of expectations and give yourself the opportunity to exceed them.

 4.      Solve Problems

Take ownership of problems

Taking ownership is one of the most important problem-solving skills in customer service. It involves taking extra efforts and accepting responsibility for finding a resolution. Problems often fall through cracks because nobody steps up to take responsibility. Many problems can be quickly fixed if just one person accepts ownership for finding a solution.          

Act on customer feedback

Any feedback comes from a customer is valuable. This feedback can be used to prevent problems from happening. One of the best ways to use customer feedback to improve service is to look for pain points.

Empathize with customer

Empathy is one of the most important customer service skills. It allows you to understand how a customer is feeling and use them to find ways to make them feel better or happy. Empathy is not always easy, but it is one of the those skills which creates a difference between good customer service and outstanding customer service.

Expand your influence

The problems we face are sometimes out of our control, but we can still provide outstanding customer service if we can find a way to leave each customer better off at end of our interactions.

Prevent negative emotions    

Working with negative or upset customer is always a challenging task in customer service. Here, preemptive acknowledgement technique is useful. This technique is used to prevent customer anger by spotting situations where a customer is likely to become angry and then addressing their negative emotions before they boil over.                        

Diffuse angry customers

Negative emotions can have a heavy influence on customers’ perceptions. Problems can even feel worse when a customer is upset or angry. According to Daniel Goleman, negative emotions hijack the rational part of the brain and people suddenly loose their ability to be reasonable until these strong emotions can be soothed. Start with a genuine desire to make angry customers feel better.

Anchor your own attitude

Friendly attitude is essential for outstanding customer service. There are times when we find ourselves in a bad mood. You can use a technique called the attitude anchor to help yourself start feeling positive once again. An attitude anchor is something that helps you anchor your attitude in a positive place. There are two types of anchors- Maintenance Anchors and Repair Anchors.

·         Maintenance Anchors – Things that help maintain a positive, upbeat, and customer-friendly attitude. Make a list of things you can do on regular basis to ensure you are in good mood. This list is personal, so it is different from person to person. For examples, Exercise, getting plenty of sleep, spending time with family or friends, etc.

·        Repair Anchors- Something that helps you get back into a positive mood when you start feeling a little grumpy. For example, take a walk, have some chocolate or cup of tea/coffee, spend a moment to talk with a co-worker, listen to music, etc.

Tips for better customer services-

  • 10 and 5 Rule- Giving non-verbal acknowledgements at 10 feet and verbal acknowledgement at 5 feet
  • Attitude Anchor- Something that helps you anchor your attitude in a positive place
  • Active Listening – Giving a full attention to the customer and purposefully trying to understand them
  • Empathy- Understand how a customer is feeling and use that insight to find ways to make them feel better
  • Need (Emotional Need and Rational Need) – The specific assistance a customer request and how a customer wants to feel about their experience
  • Non-Verbal Communication – Communication with people without using words- body language, eye contact, facial expressions, etc.
  • Five Question Technique- a technique that helps start a conversation by using five questions that will break the ice, make a customer feel more comfortable or uncover an additional opportunity to serve
  • Preemptive acknowledgement- a technique used to prevent customer anger by spotting situations where a customer is likely to become angry and addressing the negative emotions before they pea

PRAC Safety Review of Veklury (Remdesivir) on Acute Kidney Injury

PRAC 👮initiated a review on safety signal to assess reports of acute kidney injury in some patients with COVID-19 taking Veklury (remdesivir).

The PRAC has started this review based on the results from continuous signal detection work undertaken in EudraVigilance.

Veklury has given "conditional marketing approval" in the EU for the treatment of COVID-19 in adults and adolescents from 12 years of age with pneumonia who require supplemental oxygen.

A "conditional marketing approval" means more evidence required to be submitted in post-authorisation phase.

At the time of marketing authorisation application, renal toxicity was evaluated based upon animal studies and this was reflected as an important potential risk in the Risk Management Plan (RMP). This means further information required for better understanding of the effects of remdesivir on the kidney. 

The provision of additional monitoring in place to pick up reports of unwanted effects and acute kidney injury is being followed as an adverse event of special interest (AESI) in monthly summary safety reports for remdesivir. 

According to EMA, it has not been determined whether there is a causal relationship between Veklury and the reports of acute kidney injury.

The PRAC will carefully assess all available data to evaluate if the medicine may have been responsible for the kidney problems and if there is a need to update the existing information for Veklury.

The product information already advises doctors to monitor patients for renal impairment prior to and during treatment and not start treatment in patients with an important decrease in renal function.

Benadryl Challenge: FDA warns about serious problems with high doses of the allergy medicine diphenhydramine

Diphenhydramine is an antihistamine used to temporarily relieve symptoms due to hay fever, upper respiratory allergies, or the common cold, such as runny nose and sneezing.  It works by blocking histamine in the body, which is a substance that causes allergic symptoms.  When used as recommended, it is a safe and effective medicine.  Diphenhydramine is marketed under the brand-name Benadryl, store brands, and generics.  It is also available in combination with pain relievers, fever reducers, and decongestants.  

On September 24, 2020 FDA warned that taking higher than recommended doses of the common over the counter (OTC) allergy medicine diphenhydramine (brand name Benadryl) can lead to serious heart problems, seizures, coma, or even death.

FDA further added that teenagers ending up in emergency rooms or dying after participating in the “Benadryl Challenge” encouraged in videos posted on the social media application TikTok.

FDA investigating these reports and conducting a review to determine if additional cases have been reported.

FDA also contacted TikTok and strongly urged them to remove the videos from their platform and to be vigilant to remove additional videos that may be posted.  

Instruction for consumers, parents, and caregivers

Consumers, parents, and caregivers should store diphenhydramine and all other OTC and prescription medicines up and away and out of children’s reach and sight. 

FDA recommended to lock up medicines to prevent accidental poisonings by children and misuse by teens, especially when they are home more often due to the COVID-19 pandemic and may be more likely to experiment.  

Always read the Drug Facts label included on all OTC medicines to find out if they contain diphenhydramine, how much and how often you should take them, and important safety information. 

Do not take more than the dose listed on the label, as doing so can cause serious problems.  If someone takes too much diphenhydramine and is hallucinating, can’t be awakened, has a seizure, has trouble breathing, or has collapsed, immediately get medical attention or contact poison control at 1-800-222-1222 or online. 

Instruction for Health care professionals

Health care professionals should be aware that the “Benadryl Challenge” is occurring among teens and alert their caregivers about it.  Encourage teens and caregivers to read and follow the Drug Facts label.  In the event of an overdose, health care professionals should attempt to determine whether a patient with a suspected overdose took diphenhydramine.

FDA urges health care professionals and consumers to report side effects involving diphenhydramine and other medicines to the FDA MedWatch program, using the information in the “Contact FDA” box at the bottom of the page.

Updated MHRA Guidance on the PSMF for products authorized in UK

                                                                  MHRA

From 1 January 2021, for medicines authorized in Great Britain, Marketing Authorization Holder (MAH) holders must maintain PSMF that described the pharmacovigilance system for UK authorized products.

  • The PSMF must describe the global pharmacovigilance system and reflect the global availability of safety information for UK authorized products.
  • MAH need to make sure that every pharmacovigilance system covering UK authorized products has been assigned a unique PSMF number by the MHRA.
  • A UK PSMF number can be requested via the MHRA Submissions Portal from 1 January 2021.
  • A UK PSMF number can be requested via the MHRASubmissions Portal from 1 January 2021.
  • Single request for UK PSMF number should be submitted to MHRA, where the pharmacovigilance system is shared by several MAHs.
  • For MAs that are specific to Great Britain: PSMF must be accessible electronically at the same point in the UK from which the reports of suspected adverse reactions referred to in regulation 187 of the HMRs are accessible.
For MAs that are specific to Great Britain, legal requirements concerning the format and content of the PSMF are outlined in Part 1 of Schedule 12A of HMR, which mirrors Chapter I of CIR. 

  • For MAs that cover the whole of the UK or are specific to Northern Ireland: the PSMF must be located either at the site in the European Union, where the main pharmacovigilance activities are performed or at the site where the QPPV operates, in accordance with Article 7(1) of the CIR. The PSMF must be accessible electronically at the same point in the UK from which the reports of suspected adverse reactions referred to in regulation 187 of the HMRs are accessible.
For MAs that cover the whole of the UK or are specific to Northern Ireland, the legal requirements concerning the format and content of the PSMF that are outlined in Chapter I of CIR will remain unchanged.

As the legal requirements concerning PSMF format and content are identical for MAs that cover the whole of the UK and Northern Ireland, and those that are specific to Great Britain, a single PSMF can be used for all UK authorized products.
