Does organisational culture influence prescribing in care homes for older people? A new direction for research

Prescribing in care homes for older people has been the focus of much research and debate because of inappropriate drug choice and poor monitoring practices. In the US, this has led to the implementation of punitive and adversarial regulation that has sought to improve the quality of prescribing in this healthcare setting. This approach is unique to the US and has not been replicated elsewhere. The literature has revealed that there are limitations as to how much can be achieved with regulation that is externally imposed (an 'external factor'). Other influences, which may be categorised as 'internal factors' operating within the care home (e.g. patient, physician and care-home characteristics), also affect prescribing. However, these internal and external factors do not appear to affect prescribing uniformly, and poor prescribing practices in care homes continue to be observed. One intangible factor that has received little attention in this area of healthcare is that of organisational culture. This factor has been linked to quality and performance within other health organisations. Consideration of organisational culture within care-home settings may help to understand what drives prescribing decisions in this particularly vulnerable patient group and thus provide new directions for future strategies to promote quality care.     

Neuropsychotherapeutics in the UK: what has been the impact of NICE on prescribing?

The UK National Institute for Clinical Excellence (NICE) was set up in 1999 to advise the National Health Service (NHS) on the use of new technologies largely, but not exclusively, on the basis of their clinical and cost effectiveness. There have been problems with this, as with any developing system, most of which have arisen from issues not directly under the control of NICE. Despite this, NICE has already achieved a pivotal role in determining the uptake of new therapies into the NHS. In the area of neuropsychiatric therapies, NICE has examined a number of topics and has generally facilitated the increased use of the agents examined, approving the use, within limitations, of such drugs as riluzole, atypical antipsychotics and cholinesterase inhibitors. Although the use of some of these therapies had been growing, it had previously been restricted by funding in the NHS. As a result of NICE guidance, these funding restrictions have generally been lifted. NICE has rejected one area of neurological therapy so far--that of interferon-beta products and glatiramer acetate for multiple sclerosis--on the grounds of clinical uncertainty about long-term benefits and poor cost effectiveness. However, the UK Government has created a novel risk-sharing scheme in collaboration with the sponsoring companies to make these drugs available at a level of cost effectiveness acceptable to the NHS. The feasibility of this scheme is as yet unclear. This might be seen as either a triumph for NICE or as an undermining of it for political ends. One interesting aspect that is more prominent in neuropsychiatric disorders than in other areas of NICE activity has been the power of patient advocacy in encouraging acceptance of therapies where the evidence base was weak or the incremental cost-effectiveness ratio was unfavourable. The principles behind the activities of NICE attract wide support within the NHS, but the details of its decisions have often not been popular within NHS management who have to deliver them. Some of this relates more to the context and political environment within which NICE operates than to a failing within NICE itself. NICE will continue to become increasingly important in determining the use of new drugs within the UK NHS.     

Administrative initiatives for reducing inappropriate prescribing of psychotropic drugs in nursing homes: how successful have they been?

The quality of nursing home care has been subject to intense investigation and scrutiny, particularly in the US. In particular, there has long been concern about the extensive use of psychotropic agents, notably antipsychotics, hypnotics and anxiolytics, in this setting. These drugs have been described as 'chemical restraints', in that they were used to sedate and subdue patients, partly to compensate for poor staffing levels and to minimise staff contact with patients. However, following a damning Institute of Medicine report to the US Congress, use of such drugs became regulated under a unique administrative initiative: the Nursing Home Reform Act, embedded within the Omnibus Budget Reconciliation Act 1987 (OBRA 87). Research has indicated that psychotropic drug use in nursing homes has declined markedly following the implementation of this regulation. In addition, explicit criteria for potentially inappropriate medication use were incorporated within the guidelines for nursing home inspectors from 1 July 1999. Because regulations have targeted poor prescribing, rather than promoting the use of effective drugs in older residents, it has been difficult to determine whether outcomes have improved for nursing home residents as a result. However, US government agencies have responded to continuing concerns about nursing home care through the implementation of quality indicators which are used to guide and plan inspections of such facilities and to compare nursing homes within the same state. Although there are a limited number of quality indicators relating to prescribing, this represents a move away from adversarial regulation, which focuses on poor practice, and attempts to improve quality of care. An important role for educational initiatives and interventions has been advocated by some commentators and these have proved to be successful in the nursing home environment. Other countries have not implemented such restrictive prescribing regulation in nursing homes. Exemplars of innovative prescribing models, involving pharmacists and encouraging resident-centred care, may offer a more palatable approach to improving drug use in this vulnerable population.     

What aspects of treatment matter to the patient in the treatment of cocaine dependence?

Patient views of the helpful aspects of treatment were examined in the NIDA Collaborative Cocaine Treatment Study, a multi-site trial comparing four psychosocial treatments: individual cognitive therapy (CT), individual supportive expressive dynamic therapy (SE), individual drug counseling, and group drug counseling only, for the treatment of cocaine dependence. Factor analysis of the items of Helpful Aspects of Treatment measure suggested a general therapy factor, a group treatment/education factor, and a treatment structure factor. No differences were found among the four treatments on the ratings of helpfulness of these three factors, common factors, or drug intervention components. However, treatment specific cognitive therapy items (e.g. use of the cognitive model) and treatment structure differentiated individual CT from individual SE, and to a lesser extent from individual drug counseling. Ratings of helpfulness were significantly related to retention and alliance but were largely unrelated to changes in drug use or psychiatric outcomes.     

What does validation of cases in electronic record databases mean? The potential contribution of free text

Electronic health records are increasingly used for research. The definition of cases or endpoints often relies on the use of coded diagnostic data, using a pre-selected group of codes. Validation of these cases, as 'true' cases of the disease, is crucial. There are, however, ambiguities in what is meant by validation in the context of electronic records. Validation usually implies comparison of a definition against a gold standard of diagnosis and the ability to identify false negatives ('true' cases which were not detected) as well as false positives (detected cases which did not have the condition). We argue that two separate concepts of validation are often conflated in existing studies. Firstly, whether the GP thought the patient was suffering from a particular condition (which we term confirmation or internal validation) and secondly, whether the patient really had the condition (external validation). Few studies have the ability to detect false negatives who have not received a diagnostic code. Natural language processing is likely to open up the use of free text within the electronic record which will facilitate both the validation of the coded diagnosis and searching for false negatives.     

Do primary care physicians’ own AUDIT scores predict their use of brief alcohol intervention? A cross-sectional survey

BACKGROUND: To define whether the Alcohol Use Disorders Identification Test (AUDIT) scores of primary care physicians themselves predict their willingness to use brief alcohol intervention. METHODS: Cross-sectional self-administered questionnaire survey to all 3193 physicians providing primary health care in Finland. The response rate was 1909 (59.8%). Odds ratios from multinomial regression analysis were calculated for self-reported frequency (never, occasionally or regularly) of conducting brief interventions by physicians with AUDIT scores of 0-1, 2, 3, 4, 5-7 or >or=8. RESULTS: The prevalence of heavy drinkers based on AUDIT score (>or=8) was 14.5% among all physicians, 7.0% among females and 27.0% among males. Of the respondents 9.4% reported doing brief intervention regularly and 50.0% occasionally. AUDIT scores did not significantly predict either regular or occasional use of brief intervention. Instead, some other independent predictors for more frequent use of brief intervention were found. These included having a specialist licence in general practice or occupational health care and the location of the practice, but not gender or age. CONCLUSIONS: The present results indicate that in general heavy drinking among primary care physicians do not explain the low frequency with which brief intervention is used in primary health care.     

Is there an anti-inflammatory effect of statins in rheumatoid arthritis? Analysis of a large routinely collected claims database

AIM

To investigate the possible anti-inflammatory effect of statins in a cohort of rheumatoid arthritis (RA) patients.

METHODS

We conducted a cohort study consisting of all patients with at least one claim for RA using LifeLink, a health insurance claims database. Initiation and cessation of oral steroid (OS) therapy were treated as surrogate for inflammatory flare-up and controlled inflammation, respectively. We split the RA patients into two sub-cohorts based on whether they were using OS within a specified time window of the RA index date (first recorded claim for RA in the database). Cox proportional hazard models were used to evaluate the association between time-varying exposure to any statins and (i) initiation of OS therapy in the non-users of OS at RA index date and (ii) cessation of OS therapy in the users of OS at RA index date controlling for potential confounders.

RESULTS

We found 31 451 non-users of OS at RA index date and 6026 users of OS within the time window at RA index date. The results on both sub-cohorts were both consistent with no association of statin exposure with the risk of initiation/cessation of OS: the hazard ratio (HR) of initiating OS therapy was 0.96 (95% confidence interval 0.9, 1.01) in the sub-cohort of non-users and the HR of cessation of OS therapy was 0.95 (0.87, 1.05) in the sub-cohort of users of OS therapy at RA diagnosis.

CONCLUSIONS

These data do not show any beneficial effect of statins in reducing disease inflammation in RA patients.     

What is worse? A hierarchy of family-related risk factors predicting alcohol use in adolescence

The aim of the present study was to determine if family structure, perception of excessive drinking in the family, and family bonding hold a graduated importance in predicting adolescent alcohol use and their association with peers who drink excessively. Three nested linear structural models were calculated separately for frequent and excessive drinking, based on a sample of 3,127 eighth and ninth graders in Switzerland (mean age 15.3, SD 0.8) surveyed in spring 2002 in the context of the "Health Behavior in School-Aged Children (HBSC)" study. The results confirm that the perception of excessive drinking in the family is more closely related to both frequent and excessive drinking than family structure, and family bonding is more closely related than drinking perception. Adjusting for both socio-demographic variables and the association with peers who drink excessively only slightly changed the results. To predict an association with the latter, family structure was more important than the perception of drinking, but family bonding remained the predominant predictor. The results stress the graduated importance of family-related risk factors: by listening to their children's worries, by spending their free time with them, and by providing help when needed, parents might have the possibility to actively minimize the risk of frequent and excessive drinking regardless of whether they are frequent excessive drinkers or live without a partner.
