Manipulation of drugs to achieve the required dose is intrinsic to paediatric practice but is not supported by guidelines or evidence

Background: A lack of age-appropriate formulations can make it difficult to administer medicines to children. A manipulation of the dosage form may be required to achieve the required dose. This study aimed to describe medicines that are manipulated to achieve the required dose in paediatric practice.Method: A structured, undisguised observational study and postal survey. The observational study investigated drug manipulations occurring in clinical practice across three sites. The questionnaire, administered to a sample of paediatric nurses throughout the UK, surveyed manipulations conducted and nurses' experiences and views.Results: The observational study identified 310 manipulations, of which 62% involved tablets, 21% were intravenous drugs and 10% were sachets. Of the 54 observed manipulations 40 involved tablets with 65% of the tablets being cut and 30% dispersed to obtain a smaller dose. 188 manipulations were reported by questionnaire respondents, of these 46% involved tablets, 12% were intravenous drugs, and 12% were nebuliser solutions. Manipulations were predominantly, but not exclusively, identified in specialist clinical areas with more highly dependent patients. Questionnaire respondents were concerned about the accuracy of the dose achieved following manipulations and the lack of practice guidance.Conclusion: Manipulations to achieve the required dose occur throughout paediatric in-patient settings. The impact of manipulations on the efficacy of the drugs, the accuracy of the dose and any adverse effects on patients is not known. There is a need to develop evidence-based guidance for manipulations of medicines in children

Methodologies for Assessing the Acceptability of Oral Formulations among children and older adults: A Systematic Review

This review systematically identifies studies reporting on formulation aspects of oral medications that affect their acceptability in these patient groups. Particular emphasis is placed on the evaluation of the methodologies employed in the studies. Sixty-eight studies were included for analysis, with 51 (75%) in children and 17 (25%) in older populations. The studies evaluated a range of oral formulations; however, the methodologies used differ considerably in participants’ characteristics, study settings, tools, acceptability definitions and criteria. It is evident that there is a lack of standardisation in study design as well as the assessment methods used in assessing acceptability of medicines in children and older populations. This review presents a systematic analysis on methods employed for assessing acceptability of oral medicines in children and older adults, to provide insights and recommendations regarding the design of reliable instruments in future studies.Peer reviewe

Higher preference for participation in treatment decisions is associated with lower medication adherence in asthma patients.

Contains fulltext : 53471.pdf (publisher's version ) (Closed access)OBJECTIVE: To investigate the interrelations between medication adherence, self-management, preference for involvement in treatment decisions and preference for information in asthma patients in primary care. METHODS: One hundred and eighty-five patients from 43 practices completed a series of questionnaires, which included the 'Autonomy Preference Index' (API) [range=0-100], the four-item Morisky self-report medication adherence questionnaire and structured questions about asthma severity, medication and self-management. RESULTS: The mean (S.D.) for participation preference was 34.5 (15.3) whereas the mean (S.D.) for information preference was 91.1 (9.7). Higher participation preference was associated with stopping medication when feeling better (OR 1.03; 95%CI 1.01-1.06) or feeling worse (OR 1.02; 95%CI 1.0-1.05) but it was not related to asthma severity. Higher information preference was associated with non-adherence to medication (Spearman correlation coefficient 0.166; p=0.035) as well as the wish to receive asthma education (p=0.04) and usage of peak flow meter (p=0.05). CONCLUSION: Participation preference was low in general. Higher preference for involvement may entail more motivation for self-management but also lower medication adherence. This may be explained by a continuous internal negotiation process to accept the potentially lifelong demands of the disease. PRACTICE IMPLICATIONS: Patients with lower medication adherence may possibly be addressed and empowered by their enhanced preference for participation in treatment decisions. Physicians offering to share treatment decisions may utilise the patients' participation preference to enhance medication adherence. Due to varying participation preferences, optimal patient preference matching, which involves more flexible use of different communication styles, may be necessary to improve outcomes
