PRN psychotropic medications: the need for nursing research

Use of Psychotropic "Pro Re Nata" Medications by Patients Attending the Outpatient Clinic in a Hospital: A Qualitative Exploration

Introduction: Administration of psychotropic pro re nata (PRN) medications is influenced by diverse factors such as legal use of PRN medications, the attitude of patients, personal bias, and stigma toward such medication use. While PRN prescriptions increase the efficiency of care and encourage patients to participate in self-care, the use of psychotropic PRN medications by outpatients has raised concerns about its risks of harm, especially for the outpatients. This study explored the use of psychotropic PRN medications by patients attending the outpatient clinic in a hospital. Methods: Qualitative in-depth interviews were conducted. Purposeful sampling was done to achieve cases with enriched information. Participants were chosen regardless of their ethnicity and were selected using the database and patient records in the clinic. Patients 18 years of age prescribed PRN psychotropic medications attending outpatient clinics in a hospital were included. Vulnerable patients (e.g., pregnant ladies, prisoners, cognitively impaired individual, AIDS/HIV subjects, and terminally ill subjects) were excluded. Results: This study revealed the patients' perspectives and experiences on self-management of psychotropic PRN medications. The themes that emerged were clustered as education and background, knowledge on psychotropic medications, frequency of medication intake, underuse of medication, the overdose of medication, side effects concern, source of information, and personal experience. Conclusions: Patients' understanding of medication, inappropriate medication use, cues to action, and use of alternatives are the factors that affected the self-management of psychotropic PRN medications by the patients.

PRN Medicines Optimization and Nurse Education

Medicines management is a high-risk and error prone process in healthcare settings, where nurses play an important role to preserve patient safety. In order to create a safe healthcare environment, nurses should recognize challenges that they face in this process, understand factors leading to medication errors, identify errors and systematically address them to prevent their future occurrence. ''Pro re nata'' (PRN, as needed) medicine administration is a relatively neglected area of medicines management in nursing practice, yet has a high potential for medication errors. Currently, the international literature indicates a lack of knowledge of both the competencies required for PRN medicines management and the optimum educational strategies to prepare students for PRN medicines management. To address this deficiency in the literature, the authors have presented a discussion on nurses' roles in medication safety and the significance and purpose of PRN medications, and suggest a model for preparing nursing students in safe PRN medicines management. The discussion takes into account patient participation and nurse competencies required to safeguard PRN medication practice, providing a background for further research on how to improve the safety of PRN medicines management in clinical practice.

Staff and patient accounts of PRN medication administration and non-pharmacological interventions for anxiety

Most psychiatric inpatients will receive psychotropic PRN medication during their hospital stay for agitation, anxiety, and/or insomnia. While helpful in some cases, caution is warranted with regard to PRN use due to inherent risks of additional medication; therefore, experts advise that non-pharmacological interventions should be attempted first where indicated. However, research to date highlights that, in practice, non-pharmaceutical approaches are attempted in a minority of cases. While some information is known about the practice of PRN administration and the use of and barriers to implementing non-pharmacological interventions for treating acute psychiatric symptoms, full understanding of this practice is hampered by poor or altogether missing documentation of the process. This study used interviews with patients and staff from two psychiatric hospitals to collect first-person accounts of administering PRN medication for anxiety, thereby addressing the limitations of relying on documented notation found in previous research. Our results indicate that nurses are engaging in non-pharmacological interventions more often than had previously been captured in research. However, the types of strategies suggested are not typically evidence based and further, only happening approximately half the time. The barriers to providing such care are centred on two main beliefs about client choice and efficacy of these non-medical strategies. Implications for research and practice are discussed.

The use and effectiveness of pro re nata psychotropic medications in children and adolescents: A systematic review

BACKGROUND

Published studies have not demonstrated the benefits of the practice of psychotropic PRN administration.

AIM

The goal of this study is to perform a systematic review on pro re nata (PRN) psychotropic medications administration in children and adolescents and examine the safety and effectiveness of this practice in child and adolescent psychiatric care units.

SETTINGS AND DESIGN

This is a systematic review.

MATERIALS AND METHODS

Several databases were searched till date. One hundred and sixty-five titles and abstracts were found and a total of 14 studies, for which most were retrospective, met the absolute criteria. The patients studied were children, adolescents and patients that presented to the emergency room or admitted as inpatient.

RESULTS

Indications for admission included aggression and agitation for all the studies. Most the medications used include haloperidol, olanzapine, diazepam, and risperidone. Commonly reported adverse effects following the administration of the PRN medications were sleepiness, acute dystonia, and drowsiness. The effectiveness of PRN medications, which was reported in four of reviewed studies, ranged from 30% to 50%.

CONCLUSION

Different effectiveness/outcome measures were used for all the studies; therefore, we could not generalize effectiveness across all the studies. Findings of the reviewed articles show the imperativeness of more research to evaluate the safety and effectiveness of PRN medications among child and adolescent populations.

Resistance to changing practice from pro re nata prescriptions to patient group directions in acute mental health settings

Poor practice associated with pro re nata (PRN) prescriptions in mental health is known to be common and can increase the risk of serious and potentially fatal side effects. A contributing factor to poor practice is the lack of a clear chain of accountability between the decision to prescribe and administer PRN prescriptions. To address this problem, a patient group direction (PGD) for acute behavioural disturbance (lorazepam 0.5-2 mg) and staff training materials were developed. The intention was to replace PRN prescriptions with the PGD in two mental health trusts. One of the potential benefits of this would be the removal of the contribution of PRN to high and combined dose antipsychotic prescriptions. This proposal, however, was met with significant resistance in both trusts and did not replace PRN as a result. A series of interviews and focus groups were conducted with 16 RMNs working in the two trusts, to explore the reasons why the PGD was met with resistance. Senior nurses perceived resistance to be associated with anxieties over increased responsibility for decision making. Junior nurses reported concerns regarding the medicalization of the nursing role, the paperwork associated with the PGD and the training approach used. Future efforts to implement PGDs in mental health settings must carefully consider the methods for engaging effectively with participating organizations, in terms of managing change and completing the necessary groundwork for successful implementation.

Excessive dosing and polypharmacy of antipsychotics caused by pro re nata in agitated patients with schizophrenia

AIMS

It has been recommended that for patients with schizophrenia, antipsychotics should be prescribed simply, using an optimal dose. However, pro re nata (p.r.n., meaning to use on an as-needed basis) antipsychotics may increase the risk of excessive dosing (defined as mean chlorpromazine-equivalent doses above 1000 mg) and polypharmacy (combination use of different antipsychotics). This study aimed to investigate the increased risk caused by p.r.n. antipsychotics.

METHOD

The subjects included 413 patients with schizophrenia from 17 acute psychiatric wards in nine hospitals. Over a 24-h period on a survey day, data on regular medication and the use of p.r.n. were collected. The analysis focused on p.r.n. antipsychotics in agitated patients. We used McNemar's test to evaluate differences in the proportions of patients prescribed antipsychotics with excessive dosing or polypharmacy before (i.e., regular medication only) and after prescribed p.r.n. antipsychotics were added to regular medication (i.e., regular medication plus p.r.n. antipsychotics).

RESULTS

Of 413 patients, 312 (75.5%) were prescribed p.r.n. for agitated status. Of those, 281 (90.1%) were prescribed p.r.n. antipsychotics. The total doses were significantly higher and more compounded in case patients prescribed p.r.n. antipsychotics than in those who were not. Seventeen patients (4.1%) were actually administered p.r.n. antipsychotics. Their total medication, including p.r.n. on the current day, represented excessive dosing or polypharmacy of antipsychotics.

CONCLUSION

The use of p.r.n. antipsychotics may cause hidden excessive dosing and polypharmacy. Our results indicate the importance of careful monitoring of p.r.n. antipsychotics to agitated patients with schizophrenia.

The politics of knowledge: implications for understanding and addressing mental health and illness

While knowledge represents a valuable commodity, not all forms of knowledge are afforded equal status. The politics of knowledge, which entails the privileging of particular ways of knowing through linkages between the producers of knowledge and other bearers of authority or influence, represents a powerful force driving knowledge development. Within the health research and practice community, biomedical knowledge (i.e. knowledge pertaining to the biological factors influencing health) has been afforded a privileged position, shaping the health research and practice community's view of health, illness and appropriate intervention. The aim of this study is to spark critical reflection and dialogue surrounding the ways in which the politics of knowledge have constrained progress in addressing mental health and illness, one of today's leading public health issues. I argue that the hegemony of biological knowledge represents an ethical issue as it limits the breadth of knowledge available to support practitioners to 'do good' in terms of addressing mental illness. Given the power and influence inherent within the nursing community, I propose that nurses ought to engage in critical reflection and action in an effort to better situate the health research and practice community to effectively address the mental health of populations.

Patients' views and experiences of pro re nata medication in acute mental health settings

In the present study, we interviewed 40 patients in acute inpatient mental health settings regarding their experience of, and views about, receiving pro re nata (PRN) medication. Patient requests for PRN were primarily to relieve anxiety or to aid sleep, and the majority of the participants (80%) could describe a situation where this medication was very helpful. From the perspective of patients, interactions surrounding the immediate administration of PRN medication were inadequate, in that half of the interviewees were simply told to take the medication, and three-quarters said that, in their experience, formal consent was not commonly sought. Three-quarters of respondents came up with alternatives to PRN, and half wanted more information about the medication itself. These findings could contribute to improved nursing assessment for PRN medication need, administration, and monitoring.

Administration of PRN medications and use of nonpharmacologic interventions in acute geropsychiatric settings: implications for practice

Despite the known risks and the widespread administration of PRN (pro re nata or "as needed") psychotropic medications in inpatient settings, little is known about their use with hospitalized older adults. This exploratory descriptive study examined the use of PRN psychotropic medications and nonpharmacologic interventions to manage symptoms in older adults hospitalized in two acute care geropsychiatric settings. A retrospective chart audit was conducted. A major finding was the lack of documentation regarding PRN administration. In 81.3% of cases at Site A and 55.3% of cases at Site B, no reason for administration was documented. No medication response was documented in 92.4% of cases at Site A and 47.5% of cases at Site B. No nonpharmacologic interventions were documented for 69% of Site A patients or 64% of Site B patients. To ensure patient safety and to inform best clinical practice, the lack of documentation surrounding administration of PRN medications and nonpharmacologic interventions must be resolved.

A structured observation of the interaction between nurses and patients during the administration of medication in an acute mental health unit

AIMS

This aims of this study are to describe current practice in the administration of medication in an acute psychiatric unit and explore factors that influence nurses' decisions regarding the administration of medication during 'rounds'. Background.  Medication 'rounds' form part of the ward routine in many inpatient mental health settings. Nurses make several clinical decisions about administrating medication; yet, concerns have been raised about the poor assessment of patients' needs and the quality of the information exchanged.

DESIGN

A structured non-participant observational design was used for this research.

METHOD

This study involved the observation of 20 medication 'rounds' over three months. The Ward Administration of Medication Schedule was used to report on the interactions between nurses and patients and aspects of their communication during each round.

RESULTS

From the rounds observed nurses appeared adept at communicating a positive interpersonal style but less so in demonstrating skills portraying collaboration and information giving. For example whilst nurses communicated warmth in 97% of cases, using non-verbal behaviours such as good eye contact, the provision of information was only initiated in 46% of cases. Enquiries regarding the patient's general health and medication taking (35% and 17% respectively) were less commonly observed. Verbal consent was sought in only 25% of cases. Procedural matters were adhered to overall.

CONCLUSIONS

Findings suggest limited collaboration between nurses and patients and the poor monitoring of health status and medication effects. Information exchange could be improved; however, this may be related to medication procedures that make it difficult to explore sensitive information with patients, rather than nursing skills and behaviour.

RELEVANCE TO CLINICAL PRACTICE

The Ward Administration of Medication Schedule can be used as a clinical or educational tool in the administration of medication. In both instances, it may be self-administered and used to reflect on personal skills or employed as an observational tool during peer review and audit.

Psychotropic medication use among older adults: what all nurses need to know

Psychotropic medications are commonly administered to elderly clients to manage behavior and psychiatric symptoms. These drugs are known to have potentially serious side effects, to which older adults are more vulnerable. Nurses care for older adults in many different practice settings but have varying degrees of knowledge about these kinds of medications. The purposes of this article are to (a) provide information to geriatric nurses in all settings about how the most commonly prescribed psychotropic medications (i.e., anxiolytic, antidepressant, and antipsychotic drugs) differentially affect older adults; (b) examine recent concerns about the use of psychotropic medications with older adults; and (c) discuss nursing implications for those administering psychotropic medications to older adults.

Psychiatric nurses' decision to restrain

The use of restraints in all health care settings has come under increased scrutiny in recent years. Although the organizational context has been suggested as a possible influence on restraint use, few researchers have examined whether organizational factors affect use of restraints and nurses' decisions to restrain patients hospitalized in psychiatric facilities. The purpose of this study was to examine the association of nurses' work empowerment (an indicator of organizational culture) with nurses' decision to restrain. This study also examined the association between individual characteristics of the patient and of the nurses with nurses' decision to restrain. Lastly, this study examined the decision patterns used by psychiatric nurses in response to patient situations in which restraint might be considered.

Perceptions of nurses in nursing homes on the usage of benzodiazepines

AIM

This paper reports the findings of a qualitative study on how nurses perceive their own role in the use of benzodiazepines in nursing homes and to identify the factors that have an impact on the nurses' role in the use of benzodiazepines.

BACKGROUND

The use of benzodiazepines in nursing homes is of particular concern, as nursing-home residents receive considerably more benzodiazepines than non-institutionalised older persons. Evidence of their long-term effectiveness is lacking. Nurses are important partners in the decision-making process of starting and discontinuation of benzodiazepines.

DESIGN

Qualitative descriptive.

METHOD

Three focus group interviews and 10 additional semi-structured interviews were used with 33 registered nurses. The interviews were thematically analysed.

FINDINGS

Nurses' main concern is to work towards the comfort of the patient. Benzodiazepines are an easy option with not too many side effects and administration of benzodiazepines is experienced as a routine action. When prescribed they will almost automatically lead to chronic usage as there is no evaluation of their effect. There are three aspects that have an impact on nurse's perceptions of their role in benzodiazepine usage: their own individual attitude and perceptions, their knowledge and organisational factors.

CONCLUSION

Nurses do not see benzodiazepines as a problem drug and once a prescription is initiated it will almost automatically lead to chronic usage. Nurses should work towards a pro-active promotion of addressing sleeping problems and they can play a key role in non-pharmacological interventions.

RELEVANCE TO CLINICAL PRACTICE

Nurses can play a key role in suggesting non-pharmacological alternatives. Education to provide more insight into the problems of insomnia and anxiety may positively influence their attitudes and behaviour. All caregivers in nursing homes should be informed about the relevance of this issue.

A best-evidence synthesis review of the administration of psychotropic pro re nata (PRN) medication in in-patient mental health settings

AIMS AND OBJECTIVES

This paper aims to synthesise published literature of drug use/administration studies of pro re nata psychotropic medications in mental health wards.

DESIGN

The study employed a best-evidence synthesis review design.

BACKGROUND

The administration of psychotropic pro re nata medications is a frequently used clinical intervention in mental health wards. Pro re nata contributes to exposing patients to high doses of antipsychotic medication. Despite the frequent use of pro re nata, there is limited evidence of their effectiveness.

METHODS

A best-evidence synthesis review.

RESULTS

Six major themes emerged from the literature: (i) frequency of administration; (ii) administration during the 24-hour day; (iii) administration associated with length and stage of admission; (iv) rationales for administration; (v) medicines administered (including route of administration); and (vi) effects and side effects of the medicines administered.

CONCLUSIONS

Overall findings indicate that the administration of psychotropic pro re nata varies radically and appears to be influenced by many variables. Relevance to clinical practice. Patients are most likely to receive a benzodiazepine or typical antipsychotic as pro re nata. Pro re nata is an important and under-researched clinical intervention used in mental health wards.

High-dose and combination antipsychotic prescribing in acute adult wards in the UK: the challenges posed by p.r.n. prescribing

BACKGROUND

Clinical guidelines recommend the routine use of a single antipsychotic drug in a standard dose, but prescriptions for high-dose and combined antipsychotics are common in clinical practice.

AIMS

To evaluate the effectiveness of a quality improvement programme in reducing the prevalence of high-dose and combined antipsychotic prescribing in acute adult in-patient wards in the UK.

METHOD

Baseline audit was followed by feedback of benchmarked data and delivery of a range of bespoke change interventions, and then by a further audit 1 year later.

RESULTS

Thirty-two services participated, submitting data for 3,942 patients at baseline and 3,271 patients at the 1-year audit. There was little change in the prevalence of high-dose (baseline 36%; re-audit 34%) or combined antipsychotic prescribing (baseline 43%; re-audit 39%). As required ('p.r.n.') prescriptions were the principal cause of both high-dose and combined antipsychotic prescribing on both occasions.

CONCLUSIONS

The quality improvement programme did not have a demonstrable impact on prescribing practice in the majority of services. Future efforts to align practice with clinical guidelines need to specifically target the culture and practice of p.r.n. prescribing.

Service users' experiences of 'as needed' psychotropic medications in acute mental healthcare settings

AIMS

This paper reports a study which aimed to explore service users' views and experiences of the processes associated with the prescription and administration of 'as needed' (p.r.n.) psychotropic medications in acute mental health settings.

BACKGROUND

Few studies have explored the use of 'as needed' medication in acute mental healthcare settings. Such medication is frequently requested by service users, but the literature is unclear about the reasons for these requests or service users' experiences of this treatment.

METHOD

A convenience sample of 22 inpatients participated in face-to-face semi-structured interviews exploring their treatment experiences of 'as needed' psychotropic medication in acute mental health settings in a large city in the United Kingdom in 2005. Thematic content analysis was carried out.

RESULTS

Interviewees highlighted the value of 'as needed' medications. However, the process associated with their use was perceived as confusing and stigmatizing. Service users had limited understanding of and felt unsupported in attempts to use alternatives approaches. Additionally, the decision-making and information-giving processes were unclear to them, which raises issues of power and control in acute mental health settings.

CONCLUSIONS

Nurses should take account of the issues of power and control when administering 'as needed' medication. The provision of adequate treatment information should be a priority to enable informed choices to be made about this form of medication.

Mental health professionals' psychotropic pro re nata (p.r.n.) medication practices in acute inpatient mental health care: a qualitative study

OBJECTIVE

This article aims to explore mental health professionals' common clinical practices associated with the prescription and administration of pro re nata (p.r.n.) psychotropic medication within acute inpatient mental health settings.

METHOD

A convenience sample of 59 mental health professionals participated in face-to-face semistructured interviews that explored their p.r.n. psychotropic medication practices in acute mental health settings in a large city in the United Kingdom in 2005. Thematic content analysis was carried out.

RESULTS

Mental health professionals identified a number of themes that were associated with their clinical practices. These included a balanced usefulness of p.r.n. psychotropic medications, factors that influenced their decision making and use of p.r.n. as a clinical intervention and widespread variations in clinical practices. These findings have important implications on how p.r.n. psychotropic medications use differs between individuals, professional groups and organizations within acute inpatient mental health settings.

PRN sedation-patterns of prescribing and administration in a child and adolescent mental health inpatient service

OBJECTIVE

To identify utilisation rates of prn (pro re nata) sedation in children and adolescents receiving inpatient psychiatric treatment, and to compare correlates of prn prescribing and administration.

METHOD

A retrospective chart review examined 122 medical charts from a child and youth mental health inpatient service.

RESULTS

71.3% of patients were prescribed prn sedation and 50.8% were administered prn sedation. Patients received an average of 8.0 doses of prn sedation, with 9.8% receiving 10 or more doses. Chlorpromazine and diazepam were the most commonly utilised agents. Prescribing of prn sedation was only related to use of regular medications (p < 0.01), and non-parent carers (p < 0.01). In contrast, administration of prn sedation was associated with multiple diagnoses (p < 0.01), pervasive development disorder (p < 0.01), mental retardation (p < 0.01) ADHD (p < 0.01), longer hospital admission (p < 0.01), use of atypical antipsychotics (p < 0.01) and polypharmacy (p < 0.01).

CONCLUSIONS

Despite lack of data to inform practice, prn sedation is widely utilised, especially in complex patients. Future research in this area needs to incorporate nurses and examine whether patients benefit from prn sedation, which drugs and dosing patterns optimise safety and efficacy, and what is the role of prn sedation in the context of other medication.

Specialist educational intervention for acute inpatient mental health nursing staff: service user views and effects on nursing quality

AIM

This paper reports a study to evaluate the impact of an innovative 18-day educational intervention for acute ward-based mental healthcare nursing staff on documented quality of nursing care and on service user views of that care.

BACKGROUND

There are grave concerns internationally about the quality of inpatient mental health care for people with acute psychiatric problems. It is claimed that specialist educational courses are needed to improve these services. However, whilst such courses may lead to positive learning outcomes for participants, the impact on the actual care of service users is unknown.

METHOD

An uncontrolled before-and-after evaluation of three acute mental health wards from different United Kingdom National Health Service trusts was carried out. Quality of nursing care was evaluated by extracting documentary evidence from service user records, assessed by two independent researchers according to predefined quality criteria. The views of a purposive sample of mental health service users, currently receiving services from the three designated wards, were ascertained by semi-structured interview.

RESULTS

Both documentary evidence and service user views revealed some important baseline deficiencies in the quality of care offered at the study sites. Following the educational intervention, statistically significant improvements were observed in the quality of care planning, initial assessments and the provision of therapeutic care. No statistically significant changes were observed in the quality of risk assessments, medication management or external agency involvement.

CONCLUSIONS

Education can have an impact on nursing care but may not be sufficient alone to change mental healthcare practices on acute inpatient wards in the radical manner demanded by policymakers and service user lobby groups. Educational interventions need to be implemented in conjunction with organizational changes that are specifically designed to maximize the opportunities presented by a newly skilled and positive workforce.

The use and nursing management of benzodiazepines in acute, mental health inpatient care: a discussion

The use of medication in acute mental health is common practice however, there is a lack of research into all aspects of pharmacology within inpatient settings. This paper explores the specific use of benzodiazepines and areas of potential mismanagement. A number of priorities for investigation are raised and implications for nursing roles and responsibilities discussed.

Psychotropic PRN: a model for best practice management of acute psychotic behavioural disturbance in inpatient psychiatric settings

PRN, or 'as needed', medications are administered frequently by mental health nurses in psychiatric inpatient settings to manage difficult and disturbed behaviour when other strategies fail. Research indicates that approximately 50% of psychiatric inpatients receive a PRN medication at some stage of their treatment. Although evidence indicates that traditional antipsychotics and benzodiazepines are equally effective in managing acute agitation and other psychotic symptoms, it has been recommended that benzodiazepines should be the first-line of action because they do not cause the serious side-effects that are common with the traditional antipsychotics. Unfortunately, research indicates that doctors and nurses are not taking advantage of the latest evidence to guide their practice. This paper reviews the limited research available in the area and makes recommendations for evidence-based practice.
