Assessment of a United States pharmaceutical care model for nursing homes in the United Kingdom

Interventions for preventing falls in older people in care facilities and hospitals

BACKGROUND

Falls in care facilities and hospitals are common events that cause considerable morbidity and mortality for older people. This is an update of a review first published in 2010 and updated in 2012.

OBJECTIVES

To assess the effects of interventions designed to reduce the incidence of falls in older people in care facilities and hospitals.

SEARCH METHODS

We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (August 2017); Cochrane Central Register of Controlled Trials (2017, Issue 8); and MEDLINE, Embase, CINAHL and trial registers to August 2017.

SELECTION CRITERIA

Randomised controlled trials of interventions for preventing falls in older people in residential or nursing care facilities, or hospitals.

DATA COLLECTION AND ANALYSIS

One review author screened abstracts; two review authors screened full-text articles for inclusion. Two review authors independently performed study selection, 'Risk of bias' assessment and data extraction. We calculated rate ratios (RaR) with 95% confidence intervals (CIs) for rate of falls and risk ratios (RRs) and 95% CIs for outcomes such as risk of falling (number of people falling). We pooled results where appropriate. We used GRADE to assess the quality of evidence.

MAIN RESULTS

Thirty-five new trials (77,869 participants) were included in this update. Overall, we included 95 trials (138,164 participants), 71 (40,374 participants; mean age 84 years; 75% women) in care facilities and 24 (97,790 participants; mean age 78 years; 52% women) in hospitals. The majority of trials were at high risk of bias in one or more domains, mostly relating to lack of blinding. With few exceptions, the quality of evidence for individual interventions in either setting was generally rated as low or very low. Risk of fracture and adverse events were generally poorly reported and, where reported, the evidence was very low-quality, which means that we are uncertain of the estimates. Only the falls outcomes for the main comparisons are reported here.Care facilitiesSeventeen trials compared exercise with control (typically usual care alone). We are uncertain of the effect of exercise on rate of falls (RaR 0.93, 95% CI 0.72 to 1.20; 2002 participants, 10 studies; I² = 76%; very low-quality evidence). Exercise may make little or no difference to the risk of falling (RR 1.02, 95% CI 0.88 to 1.18; 2090 participants, 10 studies; I² = 23%; low-quality evidence).There is low-quality evidence that general medication review (tested in 12 trials) may make little or no difference to the rate of falls (RaR 0.93, 95% CI 0.64 to 1.35; 2409 participants, 6 studies; I² = 93%) or the risk of falling (RR 0.93, 95% CI 0.80 to 1.09; 5139 participants, 6 studies; I² = 48%).There is moderate-quality evidence that vitamin D supplementation (4512 participants, 4 studies) probably reduces the rate of falls (RaR 0.72, 95% CI 0.55 to 0.95; I² = 62%), but probably makes little or no difference to the risk of falling (RR 0.92, 95% CI 0.76 to 1.12; I² = 42%). The population included in these studies had low vitamin D levels.Multifactorial interventions were tested in 13 trials. We are uncertain of the effect of multifactorial interventions on the rate of falls (RaR 0.88, 95% CI 0.66 to 1.18; 3439 participants, 10 studies; I² = 84%; very low-quality evidence). They may make little or no difference to the risk of falling (RR 0.92, 95% CI 0.81 to 1.05; 3153 participants, 9 studies; I² = 42%; low-quality evidence).HospitalsThree trials tested the effect of additional physiotherapy (supervised exercises) in rehabilitation wards (subacute setting). The very low-quality evidence means we are uncertain of the effect of additional physiotherapy on the rate of falls (RaR 0.59, 95% CI 0.26 to 1.34; 215 participants, 2 studies; I² = 0%), or whether it reduces the risk of falling (RR 0.36, 95% CI 0.14 to 0.93; 83 participants, 2 studies; I² = 0%).We are uncertain of the effects of bed and chair sensor alarms in hospitals, tested in two trials (28,649 participants) on rate of falls (RaR 0.60, 95% CI 0.27 to 1.34; I² = 0%; very low-quality evidence) or risk of falling (RR 0.93, 95% CI 0.38 to 2.24; I² = 0%; very low-quality evidence).Multifactorial interventions in hospitals may reduce rate of falls in hospitals (RaR 0.80, 95% CI 0.64 to 1.01; 44,664 participants, 5 studies; I² = 52%). A subgroup analysis by setting suggests the reduction may be more likely in a subacute setting (RaR 0.67, 95% CI 0.54 to 0.83; 3747 participants, 2 studies; I² = 0%; low-quality evidence). We are uncertain of the effect of multifactorial interventions on the risk of falling (RR 0.82, 95% CI 0.62 to 1.09; 39,889 participants; 3 studies; I² = 0%; very low-quality evidence).

AUTHORS' CONCLUSIONS

In care facilities: we are uncertain of the effect of exercise on rate of falls and it may make little or no difference to the risk of falling. General medication review may make little or no difference to the rate of falls or risk of falling. Vitamin D supplementation probably reduces the rate of falls but not risk of falling. We are uncertain of the effect of multifactorial interventions on the rate of falls; they may make little or no difference to the risk of falling.In hospitals: we are uncertain of the effect of additional physiotherapy on the rate of falls or whether it reduces the risk of falling. We are uncertain of the effect of providing bed sensor alarms on the rate of falls or risk of falling. Multifactorial interventions may reduce rate of falls, although subgroup analysis suggests this may apply mostly to a subacute setting; we are uncertain of the effect of these interventions on risk of falling.

Therapeutic challenges in the mature patient

With the tremendous increase in the proportion of seniors in the global population, geriatric health care has become of greater interest and concern. Increased emphasis on geriatric medicine, along with the growth in the development of age-related skin disorders, has led to particular attention for geriatric, dermatology and dermatopharmacology. An aging population has brought many therapeutic challenges that we need to recognize and overcome by applying geropharmacologic principles. The purpose of this paper is to inform dermatologists of the age-related changes in the pharmacokinetics of common dermatologic drugs, their various interactions potentially occurring in the elderly, and the principles and evidence-based strategies for detection, management, and prevention to improve medication adherence. By implementing these principles and strategies, we can ensure the best and the safest treatment to promote the desired therapeutic outcome and improved quality of life for this fragile subpopulation.

Evidence-based strategies for the optimization of pharmacotherapy in older people

Geriatric pharmacotherapy represents one of the biggest achievements of modern medical interventions. However, geriatric pharmacotherapy is a complex process that encompasses not only drug prescribing but also age-appropriate drug development and manufacturing, appropriate drug testing in clinical trials, rational and safe prescribing, reliable administration and assessment of drug effects, including adherence measurement and age-appropriate outcomes monitoring. During this complex process, errors can occur at any stage, and intervention strategies to improve geriatric pharmacotherapy are targeted at improving the regulatory processes of drug testing, reducing inappropriate prescribing, preventing beneficial drug underuse and use of potentially harmful drugs, and preventing adverse drug interactions. The aim of this review is to provide an update on selected recent developments in geriatric pharmacotherapy, including age discrimination in drug trials, a new healthcare professional qualification and shared competence in geriatric drug therapy, the usefulness of information and communication technologies, and pharmacogenetics. We also review optimizing strategies aimed at medication adherence focusing on complex elderly patients. Among the current information technologies, there is sufficient evidence that computerized decision-making support systems are modestly but significantly effective in reducing inappropriate prescribing and adverse drug events across healthcare settings. The majority of interventions target physicians, for whom the scientific concept of appropriate prescribing and the acceptability of the alert system used play crucial roles in the intervention's success. For prescribing optimization, results of educational intervention strategies were inconsistent. The more promising strategies involved pharmacists or multidisciplinary teams including geriatric medicine services. However, methodological weaknesses including population and intervention heterogeneity do not allow for comprehensive meta-analyses to determine the clinical value of individual approaches. In relation to drug adherence, a recent meta-analysis of 33 randomized clinical trials in older patients found behavioural interventions had significant effects, and these interventions were more effective than educational interventions. For patients with multiple conditions and polypharmacy, successful interventions included structured medication review, medication regimen simplification, administration aids and medication reminders, but no firm conclusion in favour of any particular intervention could be made. Interventions to optimize geriatric pharmacotherapy focused most commonly on pharmacological outcomes (drug appropriateness, adverse drug events, adherence), providing only limited information about clinical outcomes in terms of health status, morbidity, functionality and overall healthcare costs. Little attention was given to psychosocial and behavioural aspects of pharmacotherapy. There is sufficient potential for improvements in geriatric pharmacotherapy in terms of drug safety and effectiveness. However, just as we require evidence-based, age-specific, pharmacological information for efficient clinical decision making, we need solid evidence for strategies that consistently improve the quality of pharmacological treatments at the health system level to shape 'age-attuned' health and drug policy.

Interventions for preventing falls in older people in care facilities and hospitals

BACKGROUND

Falls in care facilities and hospitals are common events that cause considerable morbidity and mortality for older people. This is an update of a review first published in 2010.

OBJECTIVES

To assess the effectiveness of interventions designed to reduce falls by older people in care facilities and hospitals.

SEARCH METHODS

We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (March 2012); The Cochrane Library 2012, Issue 3; MEDLINE, EMBASE, and CINAHL (all to March 2012); ongoing trial registers (to August 2012), and reference lists of articles.

SELECTION CRITERIA

Randomised controlled trials of interventions to reduce falls in older people in residential or nursing care facilities or hospitals.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed risk of bias and extracted data. We used a rate ratio (RaR) and 95% confidence interval (CI) to compare the rate of falls (e.g. falls per person year) between intervention and control groups. For risk of falling we used a risk ratio (RR) and 95% CI based on the number of people falling (fallers) in each group. We pooled results where appropriate.

MAIN RESULTS

We included 60 trials (60,345 participants), 43 trials (30,373 participants) in care facilities, and 17 (29,972 participants) in hospitals.Results from 13 trials testing exercise interventions in care facilities were inconsistent. Overall, there was no difference between intervention and control groups in rate of falls (RaR 1.03, 95% CI 0.81 to 1.31; 8 trials, 1844 participants) or risk of falling (RR 1.07, 95% CI 0.94 to 1.23; 8 trials, 1887 participants). Post hoc subgroup analysis by level of care suggested that exercise might reduce falls in people in intermediate level facilities, and increase falls in facilities providing high levels of nursing care.In care facilities, vitamin D supplementation reduced the rate of falls (RaR 0.63, 95% CI 0.46 to 0.86; 5 trials, 4603 participants), but not risk of falling (RR 0.99, 95% CI 0.90 to 1.08; 6 trials, 5186 participants).For multifactorial interventions in care facilities, the rate of falls (RaR 0.78, 95% CI 0.59 to 1.04; 7 trials, 2876 participants) and risk of falling (RR 0.89, 95% CI 0.77 to 1.02; 7 trials, 2632 participants) suggested possible benefits, but this evidence was not conclusive.In subacute wards in hospital, additional physiotherapy (supervised exercises) did not significantly reduce rate of falls (RaR 0.54, 95% CI 0.16 to 1.81; 1 trial, 54 participants) but achieved a significant reduction in risk of falling (RR 0.36, 95% CI 0.14 to 0.93; 2 trials, 83 participants).In one trial in a subacute ward (54 participants), carpet flooring significantly increased the rate of falls compared with vinyl flooring (RaR 14.73, 95% CI 1.88 to 115.35) and potentially increased the risk of falling (RR 8.33, 95% CI 0.95 to 73.37).One trial (1822 participants) testing an educational session by a trained research nurse targeting individual fall risk factors in patients at high risk of falling in acute medical wards achieved a significant reduction in risk of falling (RR 0.29, 95% CI 0.11 to 0.74).Overall, multifactorial interventions in hospitals reduced the rate of falls (RaR 0.69, 95% CI 0.49 to 0.96; 4 trials, 6478 participants) and risk of falling (RR 0.71, 95% CI 0.46 to 1.09; 3 trials, 4824 participants), although the evidence for risk of falling was inconclusive. Of these, one trial in a subacute setting reported the effect was not apparent until after 45 days in hospital. Multidisciplinary care in a geriatric ward after hip fracture surgery compared with usual care in an orthopaedic ward significantly reduced rate of falls (RaR 0.38, 95% CI 0.19 to 0.74; 1 trial, 199 participants) and risk of falling (RR 0.41, 95% CI 0.20 to 0.83). More trials are needed to confirm the effectiveness of multifactorial interventions in acute and subacute hospital settings.

AUTHORS' CONCLUSIONS

In care facilities, vitamin D supplementation is effective in reducing the rate of falls. Exercise in subacute hospital settings appears effective but its effectiveness in care facilities remains uncertain due to conflicting results, possibly associated with differences in interventions and levels of dependency. There is evidence that multifactorial interventions reduce falls in hospitals but the evidence for risk of falling was inconclusive. Evidence for multifactorial interventions in care facilities suggests possible benefits, but this was inconclusive.

Prescribing for older people in nursing homes: strategies to improve prescribing and medicines use in nursing homes

Interventions to improve prescribing in the nursing home environment are many and varied. The critical literature review presented in Paper 1 (Parsons et al., 2011, International Journal of Older People Nursing 6, 45-54) in this series discussed the main issues repeatedly identified as problematic, and this paper summarises the main approaches which have been used to attempt to improve prescribing. These include national legislation which demands documented justification for the prescribing of medicines, medication review, approaches to reducing medication errors, improving communication across care boundaries and assessment teams and alternative service models. It is difficult to make global recommendations as some of these approaches are country specific or have been delivered in different ways, involving different professionals. However, a series of prompt questions have been provided which may assist nursing home staff in deciding whether prescribing is optimal in a resident or if an intervention is required which may lead to an overall improvement in outcomes.

Pharmacy interventions on prescribing in nursing homes: from evidence to practice

Prescribing of medicines for older people who live in nursing homes is a very common intervention. Undoubtedly, medicines have contributed to longevity and improved health outcomes in the population, but they are not without their side effects and can give rise to adverse events. The nursing home population is particularly at risk as residents have multiple comorbidities and receive multiple medications. Moreover, the quality of prescribing has been criticised with long-standing concerns about inappropriate prescribing, particularly overuse of medications which are not clinically indicated or which are no longer required. It has been suggested that pharmacists could use their skills to improve prescribing in the nursing home population and this review paper outlines the evidence for this type of intervention. The studies which have been included were rigorously designed and conducted. A number of interventions consisted of medication reviews, which often focused on specific drugs, notably antipsychotics, hypnotics and anxiolytics. In some cases, the pharmacist was solely responsible for the delivery of the intervention while in others a multidisciplinary approach was taken involving other key healthcare professionals. A number of outcome measures were employed to assess the impact of the intervention, ranging from a change in the number of inappropriate medications to differences in hospitalizations or health-related quality of life. Owing to the variation across studies, it is difficult to be definitive about the impact of pharmacy interventions in this setting. In an older, frail population such as nursing home residents, consideration needs to be given to appropriate and relevant outcome measures including a reduction in inappropriate prescribing, optimization of prescribing, reduced costs and improved health-related quality of life. Pharmacists and other healthcare professionals should continue to strive to meet these challenges in this particular demographic.

A cluster randomized controlled trial of an adapted U.S. model of pharmaceutical care for nursing home residents in Northern Ireland (Fleetwood Northern Ireland study): a cost-effectiveness analysis

OBJECTIVES

To evaluate the cost-effectiveness of an adapted U.S. model of pharmaceutical care to improve psychoactive prescribing for nursing home residents in Northern Ireland (Fleetwood NI Study).

DESIGN

Economic evaluation alongside a cluster randomized controlled trial.

SETTING

Nursing homes in NI randomized to intervention (receipt of the adapted model of care; n=11) or control (usual care continued; n=11).

PARTICIPANTS

Residents aged 65 and older who provided informed consent (N=253; 128 intervention, 125 control) and who had full resource use data at 12 months.

INTERVENTION

Trained pharmacists reviewed intervention home residents' clinical and prescribing information for 12 months, applied an algorithm that guided them in assessing the appropriateness of psychoactive medication, and worked with prescribers (general practitioners) to make changes. The control homes received usual care in which there was no pharmacist intervention.

MEASUREMENTS

The proportion of residents prescribed one or more inappropriate psychoactive medications (according to standardized protocols), costs, and a cost-effectiveness acceptability curve. The latter two outcomes are the focus for this article.

RESULTS

The proportions of residents receiving inappropriate psychoactive medication at 12 months in the intervention and control group were 19.5% and 50.4%, respectively. The mean cost of healthcare resources used per resident per year was $4,923 (95% confidence interval (CI)=$4,206-5,640) for the intervention group and $5,053 (95% CI=$4,328-5,779) for the control group. The probability of the intervention being cost-effective was high, even at low levels of willingness to pay to avoid a resident receiving inappropriately prescribed psychoactive medication.

CONCLUSION

The Fleetwood NI model of care was more cost-effective than usual care.

Multidisciplinary medication review: evaluation of a pharmaceutical care model for nursing homes

OBJECTIVE

The objective of this study was to assess implementation of a pharmaceutical care model for the multidisciplinary care of elderly patients in nursing homes.

SETTING

Prospective study, medication review, from January 2007 to December 2009 in ten nursing homes affiliated to the Pharmacie interjurassienne (PIJ), Switzerland.

METHOD

Medication use data were collected and reviewed by a pharmacist, focusing on drug indication, dosing, side effects, renal/hepatic elimination and interactions. Drug-related problems (DRPs) were discussed face-to-face with the responsible physician and a nurse. The pharmaceutical care issues were formulated and medication interventions proposed during this meeting. DRPs and interventions were documented using the Pharmaceutical Care Network Europe scheme version 5.00 (PCNE V5.00). The economic impact of the service was estimated through a retrospective evaluation of annual drug costs. A satisfaction evaluation was conducted among practitioners and nurses.

MAIN OUTCOME MEASURES

DRPs, interventions, treatment changes implemented.

RESULTS

Drug therapy of 329 patients was reviewed. The number of medicines per patient ranged from 2 to 27 (mean 12.8). A total of 1,225 DRPs were detected and discussed with the physician and the nurse. Medication review led to 343 medical evaluations secondary to drug-drug interactions and 803 treatment adaptations: 373 drugs were stopped, 197 dosages changed, 95 instructions for use amended, 86 drug choices were altered, 35 drug formulations changed and 17 new drugs started. According to the Anatomical Classification System, the main classes involved in interventions were related to Alimentary tract and metabolism (n = 285), Nervous system (n = 189) and Cardiovascular system (n = 115). Since the outset of the PIJ, the annual drug costs decreased in nursing homes with medication review including a pharmacist, whereas it was stable in the other nursing homes. The satisfaction evaluation showed a very positive appreciation by practitioners and nurses.

CONCLUSION

The study showed an efficient pharmaceutical care model, well accepted by physicians and nurses. It also indicated that for elderly patients, continuous drug review contributed to improved drug therapy, reduced unnecessary polypharmacy and reduced pharmaceutical costs.

Interventions for preventing falls in older people in nursing care facilities and hospitals

BACKGROUND

Falls in nursing care facilities and hospitals are common events that cause considerable morbidity and mortality for older people.

OBJECTIVES

To assess the effectiveness of interventions designed to reduce falls by older people in nursing care facilities and hospitals.

SEARCH STRATEGY

We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (January 2009); the Cochrane Central Register of Controlled Trials (The Cochrane Library 2008, Issue 2); MEDLINE, EMBASE, and CINAHL (all to November 2008); trial registers and reference lists of articles.

SELECTION CRITERIA

Randomised controlled trials of interventions to reduce falls in older people in nursing care facilities or hospitals. Primary outcomes were rate of falls and risk of falling.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial quality and extracted data. Data were pooled where appropriate.

MAIN RESULTS

We included 41 trials (25,422 participants).In nursing care facilities, the results from seven trials testing supervised exercise interventions were inconsistent. This was the case too for multifactorial interventions, which overall did not significantly reduce the rate of falls (rate ratio (RaR) 0.82, 95% CI 0.62 to 1.08; 7 trials, 2997 participants) or risk of falling (risk ratio (RR) 0.93, 95% CI 0.86 to 1.01; 8 trials, 3271 participants). A post hoc subgroup analysis, however, indicated that where provided by a multidisciplinary team, multifactorial interventions reduced the rate of falls (RaR 0.60, 95% CI 0.51 to 0.72; 4 trials, 1651 participants) and risk of falling (RR 0.85, 95% CI 0.77 to 0.95; 5 trials, 1925 participants). Vitamin D supplementation reduced the rate of falls (RaR 0.72, 95% CI 0.55 to 0.95; 4 trials, 4512 participants), but not risk of falling (RR 0.98, 95% CI 0.89 to 1.09; 5 trials, 5095 participants).In hospitals, multifactorial interventions reduced the rate of falls (RaR 0.69, 95% CI 0.49 to 0.96; 4 trials, 6478 participants) and risk of falling (RR 0.73, 95% CI 0.56 to 0.96; 3 trials, 4824 participants). Supervised exercise interventions showed a significant reduction in risk of falling (RR 0.44, 95% CI 0.20 to 0.97; 3 trials, 131 participants).

AUTHORS' CONCLUSIONS

There is evidence that multifactorial interventions reduce falls and risk of falling in hospitals and may do so in nursing care facilities. Vitamin D supplementation is effective in reducing the rate of falls in nursing care facilities. Exercise in subacute hospital settings appears effective but its effectiveness in nursing care facilities remains uncertain.

An evaluation of an adapted U.S. model of pharmaceutical care to improve psychoactive prescribing for nursing home residents in northern ireland (fleetwood northern ireland study)

OBJECTIVES

To test the effect of an adapted U.S. model of pharmaceutical care on prescribing of inappropriate psychoactive (anxiolytic, hypnotic, and antipsychotic) medications and falls in nursing homes for older people in Northern Ireland (NI).

DESIGN

Cluster randomized controlled trial.

SETTING

Nursing homes randomized to intervention (receipt of the adapted model of care; n=11) or control (usual care continued; n=11).

PARTICIPANTS

Residents aged 65 and older who provided informed consent (N=334; 173 intervention, 161 control).

INTERVENTION

Specially trained pharmacists visited intervention homes monthly for 12 months and reviewed residents' clinical and prescribing information, applied an algorithm that guided them in assessing the appropriateness of psychoactive medication, and worked with prescribers (general practitioners) to improve the prescribing of these drugs. The control homes received usual care.

MEASUREMENTS

The primary end point was the proportion of residents prescribed one or more inappropriate psychoactive medicine according to standardized protocols; falls were evaluated using routinely collected falls data mandated by the regulatory body for nursing homes in NI.

RESULTS

The proportion of residents taking inappropriate psychoactive medications at 12 months in the intervention homes (25/128, 19.5%) was much lower than in the control homes (62/124, 50.0%) (odds ratio=0.26, 95% confidence interval=0.14-0.49) after adjustment for clustering within homes. No differences were observed at 12 months in the falls rate between the intervention and control groups.

CONCLUSION

Marked reductions in inappropriate psychoactive medication prescribing in residents resulted from pharmacist review of targeted medications, but there was no effect on falls.

Adverse Drug Reactions in Elderly People: The challenge of safer prescribing

Doctors should pay greater attention to managing the risk-benefit relationship to improve care of patients over 65, urge Jerry Avorn and William Shrank (doi: 10.1136/bmj.39520.671053.94). The challenge of safer prescribing, says Anne Spinewine, lies in shared decision making

Appropriate prescribing in elderly people: how well can it be measured and optimised?

Prescription of medicines is a fundamental component of the care of elderly people, and optimisation of drug prescribing for this group of patients has become an important public-health issue worldwide. Several characteristics of ageing and geriatric medicine affect medication prescribing for elderly people and render the selection of appropriate pharmacotherapy a challenging and complex process. In the first paper in this series we aim to define and categorise appropriate prescribing in elderly people, critically review the instruments that are available to measure it and discuss their predictive validity, critically review recent randomised controlled intervention studies that assessed the effect of optimisation strategies on the appropriateness of prescribing in elderly people, and suggest directions for future research and practice.
