The "CHROME criteria": Tool to optimize and audit prescription quality of psychotropic medications in institutionalized people with dementia

Medicine Optimisation and Deprescribing Intervention Outcomes for Older People with Dementia or Mild Cognitive Impairment: A Systematic Review

BACKGROUND

Polypharmacy is common amongst older people with dementia or mild cognitive impairment (MCI), increasing the risk of medication-related harm. Medicine optimisation and deprescribing to reduce polypharmacy is considered feasible, safe and can lead to improved health. However, for those living with dementia or MCI, this can be challenging. This systematic review aimed to summarise the evidence on the outcomes of medicine optimisation and deprescribing interventions for older people with dementia or MCI.

METHODS

Literature was searched using CINAHL, Embase, Medline, PsychINFO, Web of Science and the Cochrane Library from database inception to January 2024. Papers reporting data specific to people with dementia or MCI from medicine optimisation and deprescribing interventional research studies of any design and in any setting were included. A narrative synthesis was conducted owing to heterogeneity of study designs and outcomes. Quality was assessed using the Mixed Methods Appraisal Tool.

RESULTS

A total of 32 papers reporting on 28 studies were included, with samples ranging from 29 to 17,933 patients and a mean patient age ranging from 74 to 88 years. Of the studies, 60% were undertaken in long-term care settings. Involvement of patients and/or carers in interventions was limited. Papers were grouped as either incorporating a medication review component (n = 13), education component (n = 5) or both (n = 14). Studies primarily focussed on medication-related outcomes, generally showing a positive effect on decreasing the number and improving appropriateness of medications. Fewer papers reported clinical outcomes (behavioural and psychological symptoms of dementia, falls, quality of life and cognition) with mixed findings. A reduction or no change in mortality or hospital attendance demonstrated safety of the interventions in the few papers reporting these outcomes. The quality of the evidence was mixed.

CONCLUSIONS

Medicine optimisation and deprescribing interventions generally reduced the number and increased the appropriateness of medications, and although less frequently reported, these interventions seemed to be safe and showed an absence of worsening of clinical outcomes. This review highlights a need for further research, particularly in people with dementia or MCI living at home, with more focus on clinical outcomes and a greater involvement of patients and informal carers.

PROTOCOL REGISTRATION

The protocol was published in the International Prospective Register of Systematic Reviews (PROSPERO) [Ref: CRD42023398139].

System-level interventions for fall risk assessment, fall prevention and fall injury prevention in long-term care facilities: a scoping review

OBJECTIVES

Older adults living in long-term care facilities (LTCFs) are at high risk for falls. Interventions to prevent falls and fall-related injury in this population may be individual-level or system-focused interventions. However, relatively little attention has been given to research on system-focused interventions. This scoping review seeks to synthesise previous studies on the effects of system-focused interventions for fall prevention in LTCFs.

METHODS

We searched Ovid-Medline, CINAHL and Embase databases from 2007 to 2024 following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for Scoping Reviews. We conducted a narrative synthesis to summarise findings from the included studies.

RESULTS

In the initial search, 403 studies were identified and underwent title and abstract screening resulting in 116 articles retrieved for full-text review. 20 studies were included in the final data extraction. System-level fall prevention interventions evaluated in LTCFs include (1) multicomponent and multidisciplinary programmes, (2) environmental adaptations, (3) technological adaptations, and (4) staff education and training programmes. 11 out of 17 included quantitative studies reported significant effects of system-focused interventions to reduce falls in LTCFs.

CONCLUSIONS

This scoping review reveals the effectiveness of system-level fall prevention strategies in LTCFs. Enhancing training, customising tools and fostering a supportive leadership culture are vital for improving fall prevention practices in LTCFs.

BPSD reconsidered: diagnostic considerations to preserve personhood in persons with dementia

BPSD is relatively common but profoundly disturbing to persons with dementia, their family, and caregivers. Growing recognition of the impact of BPSD on quality of life has improved recently, but assessment and management approaches are still lacking. Considerable controversy surrounding the label of BPSD has garnered a great deal of attention, with implications of its contribution to the already pervasive dementia-related stigma experienced by persons with dementia and their caregivers. This brief review aims to summarize salient viewpoints, controversies, and considerations of the assessment, management, and perception of BPSD, in an effort to offer potential recharacterizations of BPSD to promote and prioritize personhood in persons with dementia.

Psychosis as a Treatment Target in Dementia: A Roadmap for Designing Interventions

Psychotic phenomena are among the most severe and disruptive symptoms of dementias and appear in 30% to 50% of patients. They are associated with a worse evolution and great suffering to patients and caregivers. Their current treatments obtain limited results and are not free of adverse effects, which are sometimes serious. It is therefore crucial to develop new treatments that can improve this situation. We review available data that could enlighten the future design of clinical trials with psychosis in dementia as main target. Along with an explanation of its prevalence in the common diseases that cause dementia, we present proposals aimed at improving the definition of symptoms and what should be included and excluded in clinical trials. A review of the available information regarding the neurobiological basis of symptoms, in terms of pathology, neuroimaging, and genomics, is provided as a guide towards new therapeutic targets. The correct evaluation of symptoms is transcendental in any therapeutic trial and these aspects are extensively addressed. Finally, a critical overview of existing pharmacological and non-pharmacological treatments is made, revealing the unmet needs, in terms of efficacy and safety. Our work emphasizes the need for better definition and measurement of psychotic symptoms in dementias in order to highlight their differences with symptoms that appear in non-dementing diseases such as schizophrenia. Advances in neurobiology should illuminate the development of new, more effective and safer molecules for which this review can serve as a roadmap in the design of future clinical trials.

Structured Interventions to Optimize Polypharmacy in Psychiatric Treatment and Nursing Homes: A Systematic Review

BACKGROUND

Polypharmacy is a common clinical issue. It increases in prevalence with older age and comorbidities of patients and has been recognized as a major cause for treatment complications. In psychiatry, polypharmacy is also commonly seen in younger patients and can lead to reduced treatment satisfaction and incompliance. A variety of structured polypharmacy interventions have been investigated. This systematic review provides a comprehensive overview of the field and identifies research gaps.

METHODS

We conducted a systematic review on structured interventions aimed at optimizing polypharmacy of psychotropic and somatic medication in psychiatric inpatient and outpatient settings as well as nursing homes. A search protocol was registered with PROSPERO (CRD42020187304). Data were synthesized narratively.

RESULTS

Fifty-eight studies with a total of 30,554 participants met the inclusion criteria. Interventions were most commonly guided by self-developed or national guidelines, drug assessment scores, and lists of potentially inappropriate medications. Tools to identify underprescribing were less commonly used. Most frequently reported outcomes were quantitative drug-related measures; clinical outcomes such as falls, hospital admission, cognitive status, and neuropsychiatric symptom severity were reported less commonly. Reduction of polypharmacy and improvement of medication appropriateness were shown by most studies.

CONCLUSIONS

Improvement of drug-related outcomes can be achieved by interventions such as individualized medication review and educational approaches in psychiatric settings and nursing homes. Changes in clinical outcomes, however, are often nonsubstantial and generally underreported. Patient selection and intervention procedures are highly heterogeneous. Future investigations should establish standards in intervention procedures, identify and assess patient-relevant outcome measures, and consider long-term follow-up assessments.

CHROME Criteria and Quality of Life: A Pilot Study from Maria Wolff-Albertia

BACKGROUND

Over- and potentially inappropriate prescribing of psychotropic medications is a major public health concern among people with dementia.

OBJECTIVE

Describe the CHemical Restraints avOidance MEthodology (CHROME) criteria and evaluate its effects on psychotropic prescribing and quality of life (QoL).

METHODS

Observational, prospective, two-wave study conducted in two nursing homes. A multicomponent program to eliminate chemical restraints and attain quality prescription of psychotropic medications was implemented. CHROME's diagnostic criteria comprise constellations of behavioral and psychological symptoms of dementia under six primary syndromic diagnoses. Since pharmacologic treatment is aimed at only one syndrome, polypharmacy is avoided. Psychotropic prescription, QoL, neuropsychiatric symptoms (NPS), and other clinical measurements were collected before and one year after the intervention. Results are presented for all residents (n = 171) and for completer subjects (n = 115).

RESULTS

Mean age (SD) of the residents was 87.8 (5.7), 78.9% were women, and 68.5% suffered advanced dementia. Psychotropic prescriptions decreased from 1.9 (1.1) to 0.9 (1.0) (p < 0.0005). Substantive reduction in prescribing frequency was observed for antidepressants (76.9% pre-intervention, 33.8% post-intervention) and for atypical neuroleptics (38.8% pre-intervention, 15.1% post-intervention). There was improvement in patient's response to surroundings (p < 0.0005) and total NPS (p < 0.01), but small worsening occurred in social interaction (p < 0.02, completer subjects). Safety measurements remained stable.

CONCLUSION

CHROME criteria appear to optimize psychotropic prescriptions, avoid chemical restraints, and allow external verification of quality prescriptions. Extensive use seems feasible, related to substantial reduction of prescriptions, and of benefit for people with dementia as de-prescriptions are not associated to increased NPS or QoL loss.

Syndrome-Based Prescription to Optimize Psychotropics: Are CHROME Criteria a Game Changer?

A variety of medical and social factors have contributed over the last decades to the overuse of psychotropic drugs in people with dementia. One social factor is probably the frequent failure to provide adequate person-centered care, be it in the community or in institutional settings. This unfortunate reality has been reacted upon with numerous guidelines to reduce prescriptions of the most dangerous drugs (e.g., neuroleptics). Each psychotropic drug prescription can in principle be assessed around three dimensions: (a) adequate, (b) inadequate, and (c) chemical restraint. The CHemical Restraints avOidance MEthodology (CHROME) defined chemical restraint as any prescription based on organizational convenience, rather than justified with medical diagnosis. Two validation studies revealed that one of the main medical reasons of over- and miss-prescriptions was symptom-based prescription. By switching to syndrome-based prescription, a large proportion of drugs could be de-prescribed and some re-adjusted or kept. Paucity of research and weakness of data are not conclusive about the adequacy of specific drugs for the myriad of cases presented by patients with dementia and comorbid conditions. Clinical practice, however, leads us to believe that even under optimal care conditions, psychotropics might still contribute to quality of life if based on an adequate diagnosis. This article explains the rationale that underlies a syndromic approach aimed at optimizing psychotropic treatment in people with dementia whose significant suffering derives from their thought, affective, or behavioral problems. The results of previous validation studies of this new methodology will be discussed and conclusions for future results will be drawn.

Definition and Measurement of Physical and Chemical Restraint in Long-Term Care: A Systematic Review

This systematic review aimed to identify thematic elements within definitions of physical and chemical restraint, compare explicit and implicit definitions, and synthesize reliability and validity of studies examining physical and/or chemical restraint use in long-term care. Studies were included that measured prevalence of physical and/or chemical restraint use, or evaluated an intervention to reduce restraint use in long-term care. 86 papers were included in this review, all discussed physical restraint use and 20 also discussed chemical restraint use. Seven themes were generated from definitions including: restraint method, setting resident is restrained in, stated intent, resident capacity to remove/control, caveats and exclusions, duration, frequency or number, and consent and resistance. None of the studies reported validity of measurement approaches. Inter-rater reliability was reported in 27 studies examining physical restraint use, and only one study of chemical restraint. Results were compared to an existing consensus definition of physical restraint, which was found to encompass many of the thematic domains found within explicit definitions. However, studies rarely applied measurement approaches that reflected all of the identified themes of definitions. It is necessary for a consensus definition of chemical restraint to be established and for measurement approaches to reflect the elements of definitions.

Effects of an Educational Program for Professional Caregivers on Behavioral Alterations in Nursing Home Residents: Pilot Study

This pilot study aims to analyze the effectiveness of a type of non-pharmacological intervention such as the educating and training of professional caregivers on behavioral alterations and prescription of psychotropic drugs of older adults in nursing homes. One hundred and forty-five people from two nursing homes were randomized to either treatment (educational training program for healthcare professionals) or a no-treatment group. Twenty-two professional caregivers in the experimental group received 20 h of a training program. Five data collection points were collected (pre and post, and three follow-ups, all six months apart). Intervention consisted of the behavioral alterations and psychopharmacological treatment. The analysis of variance for repeated measures showed significant differences in the time-group interaction for the educational program's effectiveness in reducing behavior alterations and psycho-pharmaceuticals' record. The results show that an improvement in the educating and training of professional caregivers can reduce behavioral alterations (F3,407 = 9.29, p < 0.001, η2= 0.063) and prescription of psychotropic drugs (F2,10 = 18.90, p < 0.001, η2 = 0.117). In addition, these effects are maintained over time. Educating health professionals on ways to care for residents who present behavioral alterations may be one alternative for improving the quality of care that residents receive. Non-pharmacological interventions, besides being individualized and adapted to the needs and experiences of individuals, achieve effects that last longer at low cost. An educational program shows new alternatives to pharmacological intervention, achieving a reduction in behavioral alterations without the costs and effects that psychopharmaceuticals entail.
