  • Safe Medication Practice Unit So these people – your predecessors PERCEIVED that they wouldn’t have any problems. Doctors don’t go out there, thinking that they will make mistakes . These are some of the reasons why…(points on slide - just need to raise awareness !)
  • Safe Medication Practice Unit Things still do look alike .
  • Safe Medication Practice Unit So thinking back to example (white ants ) When things do go wrong, there are several contributing factors . Active failures : Don’t always blame the person who makes the error . Error producing conditions : Start thinking about what has led to the error . Go and watch how nurses administer drugs... Understand how many other factors there are that the nurses have to cope with . Latent conditions See next slide .

  • Health Care SystemComposed of physician (including other medical and dental staffs), pharmacist ,nurse and other paramedicsPhysician ; diagnosis, prescription, monitoring, medical carePharmacist; prescription*, dispensing, counseling, monitoring, pharmaceutical careNurse ; administering, monitoring, nursing careOther paramedics ; their own workLoad to physician & nurse ; high due to the system of "physicians are all in all inhospital for the treatment of patient, with the help of nurse."Concept of normal public/patient ; same
  • Perceptions of Pharmacists How do others see us?
  • ”They just count a few tablets“
  • ”They just weigh and measure things“
  • ”A bunch of shop-keepers“
  • Tell me how and when to use the“”Medicine
  • ”Counter-prescribing“
  • Not really health care practitioners – they’re “”businessmen
  • ?”Do you need a degree to be a pharmacist“
  • For practising Clinical Pharmacy• Competence of health care practitioners -BPharm to Mpharm to PharmD* -PharmD+ Pre-registration + registration -Residency programs -Continuing Professional Development• Informed general public – increased expectation
  • Introduction; Clinical PharmacyClinical pharmacy may be defined as the science and practice of rationale use ofmedications, where the pharmacists are more oriented towards the patient carerationalizing medication therapy promoting health , wellness of people.It is the modern and extended field of pharmacy.“ The discipline that embodies the application and development (by pharmacist) ofscientific principles of pharmacology, toxicology, therapeutics, and clinicalpharmacokinetics, pharmacoeconomics, pharmacogenomics and other alliedsciences for the care of patients”.(Reference: American college of clinical pharmacy)
  • HistoryUntil the mid 1960’s ; Traditional role.The development of clinical pharmacy started in USA.More clinically oriented curriculum were designed with the award ofPharmD degree.These developments influenced the practice of pharmacy in U.K.,Initially prescription and drug administration records were introduced followedby an increasing pharmacy practice in hospital wards. Master degree programsin clinical pharmacy were introduced for first time in 1976.The progress of clinical pharmacy development remained at low profile in thefirst decade after its birth in U.K. However, Nuffield report in1986 geared up themomentum for progression of clinical pharmacy.Until today, the clinical pharmacy practice in Nepal is in embryonic stage.
  • How does clinical pharmacy differ from pharmacy?The discipline of pharmacy embraces the knowledge onsynthesis, chemistry and preparation of drugsClinical pharmacy is more oriented to the analysis ofpopulation needs with regards to medicines, ways ofadministration, patterns of use ,drugs effects on thePatients,‘the overall drug therapy management’.The focus of attention moves from the drug to the singlepatient or population receiving drugs.
  • Clinical Pharmacy Requirements Knowledge of drug therapy Knowledge of Knowledge of nondrug therapy the diseaseTherapeutic Knowledge of planning laboratory skills and diagnostic skills Patient careDrug Information Communication Skills skills Physical Patient assessment monitoring skills skills
  • Level of Action of Clinical PharmacistsClinical pharmacy activities may influence the correct useof medicines at three different levels:Before the prescriptionDuring the prescriptionandAfter the prescription is written.
  • 1. Before the prescription• Clinical trials• Formularies• Drug information• Drug-related policies
  • 2. During the prescription• Counselling activity• Clinical pharmacists can influence the attitudes and priorities of prescribers in their choice of correct treatments.• The clinical pharmacist monitors, detects and prevents the medication related problems• The clinical pharmacist pays special attention to the dosage of drugs which need therapeutic monitoring.• Community pharmacists can also make prescription decisions directly, when over the counter drugs are counselled.
  • Medication-related Problems• Untreated indications.• Improper drug selection.• Subtherapeutic dosage.• Medication Failure to receive• Medication Overdosage.• Adverse drug reactions.• Drug interactions.• Medication use without indication.
  • 3. After the prescription– Counselling– Preparation of personalised formulation– Drug use evaluation– Outcome research– Pharmacoeconomic studies
  • Functions of Clinical Pharmacists1. Taking the medical history of the patient2. Patient Education3. Patient care4. Formulation and management of drug policies5. Drug information6. Teaching & training to medical and paramedical staff
  • 7.Research and development8.Participation in drug utilization studies9.Patient counseling10.Therapeutic drug monitoring11.Drug interaction surveillance12.Adverse drug reaction reporting13.Safe use of drugs14.Disease management cases15.Pharmacoeconomics
  • Objective• Define clinical pharmacy• Differentiate between traditional pharmacists role and Clinical Pharmacist• Explain the qualification required for clinical pharmacists• List the clinical pharmacists responsibility• Describe the daily work activity of clinical pharmacists• Define what is Therapeutic Drug Monitoring• Discuss the different types of Therapeutic Drug Monitoring
  • Clinical pharmacy specialists• Usually requires residency in a specialty area, in addition to a pharmacy practice residency• Job functions depend on the specialty and the institution• Usually has teaching and/or research responsibilities• Represent pharmacy for medication use meeting/committee in specialty areas
  • Clinical Pharmacy Practice areas  Investigational Drugs Ambulatory care Critical care  Pharmacoeconomics Drug Information  Nephrology Geriatrics and long –term care  Obstetrics and gynecology Internal medicine and  Pulmonary disease subspecialties Cardiology  Psychiatry Endocrinology Gastroenterology  Rheumatology Infectious disease  Nuclear pharmacy Neurology  Pediatrics Nutrition Support ADR/DUE  Pharmacokinetics Transplant  Surgery
  • Various ambulatory services Anticoagulation Management Cholesterol Management Renal Management (CKD) Oncology Services Home Health Pharmacy Services Impact Pharmacy Services (Drug Conversion Program) Neonatal ICU Hypertension Management Integrated Coronary Vascular Disease (CVD) HIV/ID New Member Program (assist new MD in prescribing NF to formulary drugs) Heart Failure Management Asthma Management
  • Hospital pharmacist Vs Clinical pharmacist
  • The service including clinical pharmacy/clinical pharmacist-Patients get right care from all the facets (all the drug related problems can easily be eliminated)-Physicians n other health care professionals get more focused in theirown, work-load to them is low-Patients feel more comfortable  "Every drug is poison, it’s the dose that differentiate poison or drug the  substance is."  "To kill ill by pill, not by bill"  The last person to be involved in health care team with the patient; Pharmacist, so the system has to rely upon him/her.
  • The service without clinical pharmacy/clinical pharmacist-Due to high load to physicians and other health care professionals,the quality of patient care will be low-Most of the drug related problems cannot be easily eliminated-Patients may not feel comfortable "In developing countries like Nepal; Physicians are incompetent, Nurses are careless, Pharmacists don’t know anything(??), System is corrupted, Public is foolish, Patient load is high."...Prof Furqan Hashmi "Medicine is for those who need them, not for those who want them." "If your medicine is not working it may not be your medicine, it may be you"
  • Medicines are Dangerous
  • Pharmaceutical care• “ A practice in which a practitioner takes responsibility for a patient’s drug related needs and holds him or herself accountable for meeting these needs.”....... Linda Strand 1997• It describes specific services & activities through which an individual pharmacist cooperates with patients and other health care professionals in designing, implementing & monitoring a therapeutic plan that will produce specific outcomes for the patient.
  • • Wherein the pharmacist is engaged in; Drug monitoring, Disease monitoring, Drug therapy & disease management/collaborative practice• Pharmaceutical care is that component of pharmacy practice which entails the direct interaction of pharmacist with the patient for the purpose of caring for that patient’s drug related needsGoal of Pharmaceutical Care• Goal of pharmaceutical care is to optimize the patient’s health-related quality of life and achieve positive clinical outcomes, within realistic economic expenditures
  • Essential Components of Pharmaceutical Care1.Pharmacist-patient relationshipCollaborative effort between pharmacist & patient2.Pharmacist’s workup of drug therapy (PWDT)Provision of pharmaceutical care is centered around this,although the methods used for this purpose may vary.Components are:I.Data collection;Collect, synthesize & interpret relevant informationPatient’s demographic data: age, sex, race etc.Pertinent medical information
  • Medical history (current & past) Family history Dietary history Medication history (prescription, OTC, allergies) Physical findings (weight, height, B.P) Lab results (serum drug levels, potassium levels, serum creatinine levels relevant to drug therapy) Patient complaints, symptoms & signsII. Develop or identify the CORE pharmacotherapy plan C = condition or patient need O = outcome desired for that condition R = regimen selected to achieve that outcome E = evaluation parameters to assess outcome achievement
  • III.Identify PRIME Pharmacotherapy Problems This includes pharmacists intervention The goal is to identify actual or potential problems that could compromise the desired patient outcome P = pharmaceutical based problems R = risks to patient I = interactions M = mismatch between medication & condition or patient needs E = efficacy
  • 3.Documentation of pharmaceutical careFormulate a FARM note or SOAP note to describe or document theinterventions needed or provided by pharmacistFARM Progress NoteDescription & documentation of interventions intended or provided bypharmacistF = Findings, pt-specific information—gives basis for recognition of pharmacotherapy problems or indication for pharmacist intervention.A = Assessment, The pharmacist’s evaluation of the findings, including a statement of: Any additional information needed to best assess the problem to make recommendation The severity, priority or urgency of the problem The short term & long term goals of the intervention proposed
  • Short term goals: elimination of symptoms , Lowering of BP ,Management of acute asthma without requiring hospitalizationLong term goals:Prevent recurrence of disease,Control B.P.,Prevent progression of diabetesR = Resolution, including prevention Observing & reassessing Counseling or educating the patients & care givers Informing the prescriber Making recommendation to prescriber Withholding medication or advising against useM = Monitoring to assess the efficacy, safety & outcome of the intervention This should includeThe parameters to be followed (e.g. pain, depressed mood, serum levels)The intent of monitoring e.g. efficacy, toxicity, adverse eventsHow the parameters will be monitored e.g. interview patients, serum druglevel, physical examination
  • Frequency of monitoring—weekly or monthly Duration of monitoring e.g. until resolved, while on antibiotics,then monthly for one year Anticipated or desired finding e.g. no pain, healing of lesion Decision point to alter therapy when or if outcome is not achieved e.g. pain still present after 3 days, mild hypoglycemia more than 2 times a week.SOAP Note ; This is used primarily by physicians, S=subjective findings O=objective findings A=assessment P=plan
  • Clinical skills & pharmacist’s role in Pharmaceutical CarePatient assessmentPhysical assessmentBarriers to adherencePsychosocial issuesEducation & counselingInterview skillsCommunication skills (e.g. empathy, listening, speaking orwriting at patients level of understanding)Ability to motivate & inspireDevelop & implement patient education plan based on an initialeducation assessmentIdentification & resolution of compliance barriers

  • Erythemal rash from penicillin – in patient with a previousKnown allergy/ adverse drug reaction
  • Necrotising fascititis – secondary to infection at site of IV injection
  • Acute Liver failure from Black Cohosh - herbal medicine
  • Human Error (Mistakes, Slips, Lapses) Error is inevitable due to “our” limitations: - limited memory capacity - limited mental processing capacity - negative effects of fatigue other stressors We all make errors all the time Generalised lack of awareness that causes errors Patients suffer adverse events much more often than previously realised Errors often NOT immediately observed The same error, even a minor one, can have quite different consequences in different circumstances.
  • The System: !Only as safe as it’s designed to be“I assumed the brown glass ampoule was frusemide”
  • The Accident Causation Model (Adopted from Reason & Dean) Error Active Latent Failures producingConditions Slips&lapses- conditions Mistakes- Accident Defences
  • Sources of ErrorPrescribing error - selecting the wrong or inappropriate •drug/dose/formulation/duration etcCommunicating those instructions •Supply error - timely; wrong drug, dose, route; expired •.medicines, labellingAdministration error - timing; wrong route; wrong •.rate/technique.Lack of user education - actions to take •
  • Drug therapy assessmentSix types of problems which may result in treatmentfailure : Inappropriate selection of medication.1 Inappropriate formulation of medication.2 Inappropriate administration of drug therapy.3 Inappropriate medication-taking behaviour.4 1. Inappropriate monitoring of drug therapy.5 Inappropriate response to drug therapy.6
