Clinical checks examples

The following section contains examples of requisitions that may be encountered in a community pharmacy. In each case, the following sections have been completed to guide you through the dispensing process (note that compared to the dispensing of NHS prescriptions (see Section 3.5.2) and non-NHS (private) prescriptions (see Section 5.5.2), there is no need to perform a clinical check (except for some patient-specific written requests from optometrists), check for inter-... 

A good look at the index of this book indicates the items commonly encountered in examinations. The index is an exhaustive one and is divided into proprietary names, generic names, subject areas and conditions. A self-assessment exercise is to check that you have adequate knowledge of examples of the topics listed above and then attempt the tests. A review of the drugs in the index provides examples of medicines that certainly need attention. You should be familiar with the action, classification, side-effects, clinically significant drug interactions, contraindications and cautions of a number of classes of drugs, such as ... 

There should be consistency between the possible adverse events described for the study drug in the protocol, investigator s brochure and ICF. Most coimtries have specific requirements for their ICF. It is essential that the requirements are known when the country-specific ICF is prepared. These examples could easily have changed by the time the reader is checking an ICF. In the United Kingdom, reference should be made to the ABPI (Association of the British Pharmaceutical Industry) Clinical Trial Compensation Guidelines. In other countries, for example, Ireland, the study subject is allowed a specific length of time to decide whether to enter the study. 

For practical purposes people frequently find it convenient to identify a normal range for a particular parameter. For example, clinically, we may measure all sorts of ions and enzymes in a patient s blood and then we want to be able to spot any abnormal values that may be of importance in diagnosis and treatment. To make it easier to spot these interesting values, clinicians like to establish a normal range for each substance measured. Then, all they have to do is check for values outside the official normal range. 

Material Selection of appropriate material for examination is mainly determined by the time that has elapsed from administration of the toxic substance to collection of the material, as well as the site of conducting examinations (a clinical or forensic laboratory, or the site of the incident, for example, during a roadside check of a driver). Various compounds occur in various materials - parent, and active and inactive metabolites. Active metabolites influence life processes, and the presence of inactive metabolites in the organism could attest to consumption of a substance a long time ago. Currently available analytical techniques are applied to detect, identify and determine chemical substances in classical biological material (i.e. blood, urine and sections of internal organs) as well as in so-called alternative materials (i.e. hair, saliva and sweat). In recent years, numerous studies aimed at... 

IEF can also be carried out under denaturing conditions, for example in the presence of 9 M urea. For the analysis of hydrophobic proteins, non-ionic detergents such as Nonidet NP-40 or Triton X-100 can be added to the sample and the IEF gel. Analytical IEF is used to determine the pi of proteins, and also as a critical check of the homogeneity of protein preparations. The reprodudbility and resolving power of the technique is exploited in various applications where it is used to establish the identity and complexity of protein mixtures for example in food analysis, the origin of proteins in milk preparations, and in clinical analysis, determining the isoenzyme profile of apolipoproteins. 

Figure 1.5 contains an example of a clinical intervention form. This is a form used within a pharmacy to record any clinical interventions made. During the professional check of a prescription form, the pharmacist may note areas that require further action (for example, contacting the prescriber to confirm a dose, etc.). Once any appropriate action has been taken, a note of the action taken is made on a clinical intervention form. These forms can then also be used for audit purposes. 

Visit dates. All visit dates should be recorded in the medical file. Interim visit dates recorded in the medical file, but not in the CRF, should be noted by the monitor in case they signify occurrence of AEs or protocol violations. The final visit date should be so indicated, for example study finished or withdrew from study AEs. All AEs noted in the medical file during the time period specified by the protocol must be recorded in the CRF. The monitor must also carefully check other documents (e.g. diary cards, quality of life forms) for sources of information about AEs. Occurrence of out-of-range laboratory values, which are considered to be clinically significant by the investigator, must be reported and assessed as AEs...
