Home detoxification for problem drinkers: acceptability to clients, relatives, general practitioners and outcome after 60 days

Management of alcohol detoxification

The huge majority of people with an alcohol dependence problem that is uncomplicated by serious mental illness or social chaos receive treatment in the community.Tackling Alcohol Together: The Evidence Base of a UK Alcohol Policy(Raistricket al, 1999, chapter 9) provides strong evidence supporting the move towards briefer and community-based treatments, while at the same time recognising the need for intensive and in-patient treatments for people with more complicated problems. It follows that the traditional sequencing of care, which might be characterised as having four phases – assessing and engaging patients, detoxification, specific therapy and aftercare – is less tidy than it used to be. Detoxification is seen much more as a standalone procedure that should be undertaken when the patient is ready, rather than as a prerequisite of starting treatment. Of course, there are also instances where detoxification may be required as an expedience, for example during an unplanned admission into hospital, or where regular high levels of intoxication are a barrier to treatment. Equally, where the focus of treatment is on mental illness rather than alcohol dependence, then detoxification may well be viewed as a necessary first step.

Unplanned alcohol withdrawal: a survey of consecutive admissions to an acute medical unit in 2010 and 2011

BACKGROUND

Alcohol-related presentations to hospital have been increasing in the UK in recent years, including the occurrence of acute withdrawal. This study sought to better characterize the clinical features, patterns of treatment and outcomes in this patient group.

METHODS

Patients admitted to the Acute Medical Unit of York Hospital due to acute alcohol withdrawal are normally treated according to a protocol that involves both fixed-dose and symptom-triggered drug administration. Admissions between 2010 and 2011 inclusive were studied.

RESULTS

There were 211 admission episodes solely due to acute alcohol withdrawal, involving 127 patients (97 men, 76.4%) with median age of 45 years (interquartile range: 39-52 years). There was a high prevalence of depression (34%), alcoholic liver disease (22%) and drug misuse (12%). Total dose of chlordiazepoxide varied between 0 and 610 mg and tapered rapidly after the first day of admission. Vitamin supplements were administered to >90% of patients, including parenteral and oral in 74%, parenteral alone in 9% and oral alone in 9%. A specialist alcohol nurse reviewed patients while in hospital in 40% of cases. Approximately one-third of patients had multiple admissions for alcohol withdrawal during the study period.

CONCLUSION

A high prevalence of physical and mental health disorders was observed. The local policy permitted high initial chlordiazepoxide doses and prompt downward titration, with a broad range of doses between individuals. Approximately 10% required no specific therapy, and there may be opportunities for developing alternative pathways for delivery of care in an ambulatory setting for these patients.

Packages of care for alcohol use disorders in low- and middle-income countries

In the fourth in a series of six articles on packages of care for mental disorders in low- and middle-income countries, Vivek Benegal and colleagues discuss the treatment of alcohol use disorders.

Process evaluation of an out-patient detoxification service

This paper describes the process evaluation of an out-patient detoxification service (ODS) established by Drug Health Services (DHS) to increase the supervised withdrawal options for substance users in a Sydney metropolitan Area Health Service. The ODS aimed to provide a safe and effective supervised withdrawal to substance users who were at low risk of severe withdrawal, engage those with severe dependence in further treatment and increase the involvement of general practitioners (GPs) in the medical care of ODS clients. During its first 10 months of operation, the ODS received 199 inquiries, assessed 82 individuals and admitted 76 clients for detoxification. Withdrawal treatment proceeded without complications and within the expected time frames. Fifty-four clients completed withdrawal, 10 ceased treatment, 10 remained in treatment without completing withdrawal and two were transferred elsewhere. Clients who injected substances (mainly heroin) daily at admission, compared to others, were less likely to complete withdrawal and more likely to use a range of non-prescribed substances during withdrawal. One-fifth of clients went on to further treatment with DHS, attending at least once. Overall, the ODS met its goals, providing a safe and effective supervised withdrawal to local residents, especially women, young people and those withdrawing from benzodiazepines who had significant substance dependence, impairment and previous alcohol and other drug (AOD) treatment. Non-injecting substance users benefited most from the ODS in terms of withdrawal completion and ongoing treatment. The level of GP involvement in the conjoint care of ODS clients remained constant over time. The development and expansion of the ODS are discussed.

Detoxification: the basis of current practice

With chronic use of a psychoactive drug the central nervous system undergoes a series of changes. These changes vary both in nature and in extent with each drug, but in general, they alter the responsiveness of the nervous system to the drug so as to reduce the perceived clinical effect, and also alter the innate responsiveness of the affected neurons to various stimuli. With cessation of drug use the nervous system undergoes a natural healing which consists of a restoration of normal responsiveness, but this process takes some time during which the patient's responses are abnormal and they are vulnerable to a variety of stressors. Detoxification is the safe negotiation of this period.

Effectiveness of home detoxification: a clinical audit

AIM

An audit of home detoxifications undertaken during a 2-year period in a community drug and alcohol service was performed to explore the impact of suitability criteria on the successful completion of the intervention, and to inform future practice.

METHOD

A retrospective analysis of home detoxifications was undertaken in a community setting using a designed audit tool.

RESULTS

Of the 154 referrals for home detoxification, 59 commenced detoxification and 95 did not. The absence of a suitable carer and a pre-existing medical-psychiatric condition were the main reasons for home detoxification being deemed an unsuitable intervention. Of those who commenced detoxification, 96.6% completed the programme.

CONCLUSION

Clear and rigorous screening by an experienced professional before home detoxification is commenced is important to ensure positive treatment outcomes; however, more can be done to improve the service offered and ensure appropriate referrals.

Starting clozapine in the community: a UK perspective

Clozapine is the most effective antipsychotic available for the treatment of schizophrenia that has proved resistant to other medications and the only antipsychotic licensed for this indication. Although the drug is increasingly being used more widely in patients with schizophrenia and with other psychiatric and neurological disorders, it is still underused. The main reasons for this are that it can cause adverse effects such as weight gain and sedation, and the need for regular blood test monitoring because of the risk of agranulocytosis. While these hurdles are unavoidable, another problem in the UK has been the historical practice of admitting patients to hospital to initiate treatment with clozapine. However, protocols have now been developed for both home and day-hospital initiation. The experience of one assertive community treatment team of starting clozapine in patients' own homes has been positive, with no major adverse events reported. This approach is, however, extremely demanding of staff resources and for many services the use of day-hospitals to initiate treatment with clozapine is more appropriate. Research into staff and patients' views about community initiation of clozapine, and its economic costs, would be welcome.

Self-detoxification attempts among methadone maintenance patients: what methods and what success?

In a study of patients attending a methadone maintenance clinic in South London, 66 of 114 (58%) had previously attempted to detoxify themselves from opiates without medical assistance. The total number of self-detoxification attempts was 237, an average of 3.6 attempts per individual. Forty subjects (61%) reported attempting self-detoxification with the help of drugs or alcohol. The drugs most commonly used were diazepam, alcohol, and cannabis. The most commonly reported reasons for attempting self-detoxification were "fed-up with the lifestyle" (61%) and "for their family" (12%). The reasons given for why patients had decided to detoxify themselves rather than access treatment services included 23% who reported that "they could cope on their own and that they didn't need any help." The short-term success rate (abstinent for at least 24 hours) was moderate, at 41% (97/237). Patients who had been unsuccessful were asked why their last self-detoxification attempt had not resulted in abstinence, with 27% reporting that they were "tempted to use again" and 23% reported that they "didn't know why they started using again." The prevalence of both attempts and success suggests that, for some opiate users, self-detoxification may be a pathway to abstinence.

Utilization of acute inpatient services for alcohol detoxification

This study indicates that the majority of patients admitted to VA hospitals for medical detoxification could have those services provided on an outpatient or less intensive basis. However, inpatient medical detoxification services appear to be appropriate for those alcoholics at risk for potential life-threatening complications of withdrawal such as delirium tremens, or those with concurrent associated medical conditions such as pancreatitis, gastrointestinal bleeding, or complications of cirrhosis. Data were obtained from a national random sample of hospitalizations in Department of Veterans Affairs (VA) inpatient medical and surgical units. Medical records for 144 alcoholism-related medical admissions to 35 VA medical centers were reviewed using the Appropriateness Evaluation Protocol (AEP), a clinically based utilization review instrument widely used in the private sector. The medical records for the admission and each day of medical/surgical inpatient stay were reviewed using clinical criteria for the appropriateness of acute inpatient care as opposed to lower levels of care.

Ambulatory medical detoxification for alcohol

In the past decade, ambulatory medical detoxification for alcohol withdrawal has become increasingly utilized due to pressures to contain cost of treatment and research demonstrating its effectiveness. The research that describes this area spans the last 15 years. This article reviews the available literature on ambulatory detoxification and attempts to summarize and synthesize what is known about this area in order to make ambulatory medical detoxification readily reproducible in clinical practice. Finally, this article concludes with an analysis of the advantages and disadvantages of outpatient alcohol detoxification as compared to inpatient treatment.

High risk drinking settings: the association of serving and promotional practices with harmful drinking

A household survey of 1160 Western Australian adults was used as a basis for exploring drinkers' reports about the settings in which they drank alcohol and their experiences of alcohol related harm. Of the 873 drinkers identified, 7.9% had experienced some form of acute alcohol related harm over the previous 3 months. Violent incidents were the most common of these and drink-driving offences the least. Such harm was significantly more likely among drinkers who variously drank 'heavily', were male, single, under 25 years of age and/or who drank on licensed premises. Regression analyses revealed that even when demographic characteristics of the drinkers were controlled for licensed premises were significantly more likely to be the settings used prior to harm occurring. Bar staff continuing to serve 'obviously intoxicated' customers was the most powerful predictor of harm. Premises which offered discounted drinks or permitted crowding also tended to be those where intoxication was permitted but these variables were not directly associated with an increased risk of harm. These findings lend further weight to the view that prevention efforts should focus on licensed drinking environments and, in particular, the practice of continuing to serve obviously intoxicated customers.
