Improving drug compliance after hospital discharge.

The effect of counselling on medication errors was assessed in 165 elderly patients after leaving hospital. Counselling was effective, with counselled patients making under one-third of the errors made by uncounselled patients. Three types of memory aid were tried to supplement counselling. The pill wheel increased errors, a tablet identification card was unhelpful, and only a tear-off daily calendar seemed to improve results modestly. Counselling was virtually as effective in improving compliance in poorly orientated patients. A designated member of staff should spend about 15 minutes with each elderly patient before discharge to ensure that the discharge drug regimen is fully understood and remembered, that old tablets are destroyed and that other people''s tablets are not taken.     

Adverse events among medical patients after discharge from hospital

BackgroundAdverse events (AEs) are adverse outcomes caused by medical care. Several studies have indicated that a substantial number of patients experience AEs before or during hospitalization. However, few data describe AEs after hospital discharge. We determined the incidence, severity, preventability and ameliorability of AEs in patients discharged from the general internal medicine service of a Canadian hospital.MethodsAt a multisite Canadian teaching hospital, we prospectively studied patients who were consecutively discharged home or to a seniors'' residence from the general internal medicine service during a 14-week interval in 2002. We used telephone interview and chart review to identify outcomes after discharge. Two physicians independently reviewed each outcome to determine if the patient experienced an AE. The severity, preventability and ameliorability of all AEs were classified.ResultsDuring the study period, outcomes were determined for 328 of the 361 eligible patients, who averaged 71 years of age (interquartile range 54–81 years). After discharge, 76 of the 328 patients experienced at least 1 AE (overall incidence 23%, 95% confidence interval [CI] 19%–28%). The AE severity ranged from symptoms only (68% of the AEs) or symptoms associated with a nonpermanent disability (25%) to permanent disability (3%) or death (3%). The most common AEs were adverse drug events (72%), therapeutic errors (16%) and nosocomial infections (11%). Of the 76 patients, 38 had an AE that was either preventable or ameliorable (overall incidence 12%, 95% CI 9%–16%).InterpretationApproximately one-quarter of patients in our study had an AE after hospital discharge, and half of the AEs were preventable or ameliorable.The Institute of Medicine report Crossing the quality chasm identifies patient safety as a prerequisite to high-quality care.¹ The need to improve safety is highlighted by research showing that hospitalized patients have a high risk of adverse outcomes resulting from treatment. For example, the Harvard Medical Practice Study found that adverse events (AEs) occurred in 3.7% of hospitalized patients.^2,3 Similar studies have found equivalent or greater rates.^4,5,6 Other research has found that AE risk increases with design flaws in the health care system.^7,8,9,10Such flaws may particularly affect patient care immediately after hospital discharge, a period associated with discontinuities in providers and in location of care. Some authors suggest that such “gaps” are important causes of error.¹¹ It is also a time when patients frequently experience extensive changes in health¹² and therapy.¹³ Finally, communication between hospital and community physicians can be inadequate.¹⁴ For these reasons, AEs may be common after discharge. A recent study, by a group that included 1 of us, found that 19% of medical patients discharged from a single teaching hospital in the United States experienced an AE within a month.¹⁵ One-third of these AEs were preventable because they were due to an error. Another third were judged “ameliorable” because their severity could have been reduced with better monitoring or earlier response to the problem.¹⁵That study was important, but it had limitations. It was carried out in a single, very specialized institution, it relied on data available in an electronic medical record, and it had a high rate of loss to follow-up. To address these concerns, we carried out a new study to determine the risk, severity and type of AEs after discharge from 2 campuses of a Canadian teaching hospital.     

Community care for patients with schizophrenia one year after hospital discharge.

OBJECTIVES--To document the circumstances and care of patients with schizophrenia who had recently been discharged from local psychiatric inpatient services, and to establish the extent to which misgivings about community care might be justified. DESIGN--Cross sectional surveys with review of case notes. Follow up interviews with questionnaires administered one year after discharge. SETTING--Two inner London districts (West Lambeth and Lewisham) with high levels of social deprivation and at different stages of developing community services. PATIENTS--90 and 50 patients in the two services respectively, aged 18 to 65, who satisfied the Research Diagnostic Criteria for schizophrenia and who were discharged from inpatient services. MAIN OUTCOME MEASURES--Diagnosis elicited by present state examination, global social disability rating, use of services during the three months before interview. RESULTS--89 of the 140 patients (64%) had been ill for five or more years, yet few were former long stay inpatients. 55% (50/91; 95% confidence interval 45% to 65%) of those interviewed had current psychotic mental states and 22% (27/124; 16% to 31%) were functioning socially at very poor or severely maladjusted levels. 86% (107/124) were unemployed. The majority of patients had seen a mental health or social service professional, yet only 16% (20/124) were in specialised accomodation (excluding hospitals) and only 23% (17/73) of those eligible had used day care. Small numbers of people had experienced homelessness (two) or imprisonment (four over six months). CONCLUSIONS--Many schizophrenic patients leaving local psychiatric inpatient care have active symptomatology and profound social disabilities. Community care was characterised by high rates of contact with service professionals but little supported accommodation or day activity. This group of clients may require dedicated provision, which would actively encourage them to use services protected from the demands of those with less severe illness.     

Behavioural treatment of urinary incontinence in geriatric patients.

Urinary incontinence and a program to treat it were studied in a geriatric hospital. Of 161 men, 58 (36%) were incontinent. The most common probable causes were cerebrovascular accident and organic brain syndrome. Evaluation by cystometry (after treatment of infections) in 30 patients showed 24 (80%) to have detrusor hyperreflexia. Twenty patients with hyperreflexia completed a timed-voiding routine, which benefited 17 of them (85%).     

Association between frailty and 30-day outcomes after discharge from hospital

Background:Readmissions after hospital discharge are common and costly, but prediction models are poor at identifying patients at high risk of readmission. We evaluated the impact of frailty on readmission or death within 30 days after discharge from general internal medicine wards.Methods:We prospectively enrolled patients discharged from 7 medical wards at 2 teaching hospitals in Edmonton. Frailty was defined by means of the previously validated Clinical Frailty Scale. The primary outcome was the composite of readmission or death within 30 days after discharge.Results:Of the 495 patients included in the study, 162 (33%) met the definition of frailty: 91 (18%) had mild, 60 (12%) had moderate, and 11 (2%) had severe frailty. Frail patients were older, had more comorbidities, lower quality of life, and higher LACE scores at discharge than those who were not frail. The composite of 30-day readmission or death was higher among frail than among nonfrail patients (39 [24.1%] v. 46 [13.8%]). Although frailty added additional prognostic information to predictive models that included age, sex and LACE score, only moderate to severe frailty (31.0% event rate) was an independent risk factor for readmission or death (adjusted odds ratio 2.19, 95% confidence interval 1.12–4.24).Interpretation:Frailty was common and associated with a substantially increased risk of early readmission or death after discharge from medical wards. The Clinical Frailty Scale could be useful in identifying high-risk patients being discharged from general internal medicine wards.Readmissions within 30 days after hospital discharge are common and costly occurrences. Although many studies have attempted to identify patients at highest risk of readmission, neither experienced clinicians nor experienced researchers using rigorously developed administrative data-rich algorithms can accurately predict which patients will not successfully transition back into the community.^1–6 This suggests that currently unrecognized factors likely play a major role in readmission risk. Identification of these factors would be important for future initiatives to reduce readmission rates by targeting resources to those at highest risk.Frailty is a frequently underdiagnosed condition, with prevalence estimates ranging from 27% to 80% among inpatients^7–9 and from 4% to 59% among older adults living in the community,¹⁰ depending on the frailty measure used and the population evaluated. Frailty is a multidimensional syndrome of decreased reserve and resistance to stressors leading to increased vulnerability to adverse outcomes.^11–14 The 2 models of frailty most commonly used in the literature are the phenotype model (e.g., the approach proposed by Fried and colleagues,¹⁵ which is based on 5 objective variables assessed at one point in time that do not include psychosocial and cognitive variables) and the cumulative deficit model (e.g., the Clinical Frailty Index, which is based on a mix of more than 30 variables capturing function in many domains over time).^16–18Although the gold standard for frailty assessment is a comprehensive geriatric assessment by a multidisciplinary team, both the phenotype and cumulative deficit models appear reasonably accurate for identifying frailty. However, both are somewhat cumbersome for routine use at the bedside.¹² For these reasons, the Clinical Frailty Scale was developed and relies on clinical judgment based on history taking and clinical examination. The Clinical Frailty Scale is easy to administer at the bedside; has been used by physicians, allied health professionals and research assistants; does not require any special equipment; is highly correlated with the Fried frailty index (r = 0.8);¹⁷ and appears to be valid, reliable and reproducible.¹⁹ Some risk-prediction models, such as the LACE Index, have tried to incorporate frailty, but they did not find it to be a significant independent variable, possibly owing to the frailty measure used. A systematic review of 30 risk-prediction models for hospital readmission found that only 2 included functional status.⁴We conducted a study to evaluate whether frailty identified using the Clinical Frailty Scale is an independent predictor of death or readmission within 30 days after discharge from hospital.     

Study of "discharge communications" from hospital.

All hospital discharge communications concerned with acute admission from one general practice over a three month period were analysed. There was an appreciable delay between the time that the patient was discharged and the information was received by the general practitioner. Just over half of the patients had contacted their general practitioner after discharge before the general practitioner had received any information. The content of the communications was variable, and important subjects were frequently omitted. No communication was received for 11% of the discharged patients. There is a need for more efficient communication between secondary and primary care.     

Effectiveness of a geriatric day hospital.

OBJECTIVE: To determine whether there is a difference in the quality of life between elderly patients managed in a day hospital and those receiving conventional care. DESIGN: Randomized controlled trial; assessment upon entry to study and at 3, 6 and 12 months afterward. SETTING: Geriatrician referral-based secondary care. PATIENTS: A total of 113 consecutively referred elderly patients with deteriorating functional status believed to have rehabilitation potential; 55 were assessed and treated by an interdisciplinary team in a day hospital (treatment group), and 58 were assessed in an inpatient unit or an outpatient clinic or were discharged early with appropriate community services (control group). OUTCOME MEASURES: Barthel Index, Rand Questionnaire, Global Health Question and Geriatric Quality of Life Questionnaire (GQLQ). MAIN RESULTS: Eight study subjects and four control subjects died; the difference was insignificant. Functional status deteriorated over time in the two groups; although the difference was not significant there was less deterioration in the control group. The GQLQ scores indicated no significant difference between the two groups in the ability to perform daily living activities and in the alleviation of symptoms over time but did show a trend favouring the control group. The GQLQ scores did indicate a significant difference in favour of the control group in the effect of treatment on emotions (p = 0.009). CONCLUSION: The care received at the day hospital did not improve functional status or quality of life of elderly patients as compared with the otherwise excellent geriatric outpatient care.     

The TAPS project. 17: Readmission to hospital for long term psychiatric patients after discharge to the community.

OBJECTIVE--To identify risk factors which increase the likelihood of readmission for long stay psychiatric patients after discharge from hospital. DESIGN--Follow up for five years of all long stay patients discharged from two large psychiatric hospitals to compare patients readmitted and not readmitted. SETTING--Friern and Claybury Hospitals in north London and their surrounding catchment areas. Most patients were discharged to staffed or unstaffed group homes. SUBJECTS--357 psychiatric patients who had been in hospital for over one year, of whom 118 were "new" long stay and 239 "old" long stay patients. MAIN OUTCOME MEASURES--Readmission to hospital and length of subsequent stay. RESULTS--Of all discharged patients 97 (27%) were readmitted at some time during the follow up period, 57 (16%) in the first year after discharge, and 31 (9%) then remained in hospital for over a year. The best explanatory factors for readmission were: male sex, younger age group, high number of previous admissions, higher levels of symptomatic and social behavioural disturbance, a diagnosis of manic-depressive psychosis, and living in a non-staffed group home. CONCLUSIONS--During the closure of psychiatric hospitals, facilities need to be preserved for acute relapses among long term, and especially younger, discharged patients. Staffed group homes may help prevent relapse and reduce the number of admission beds required.     

Effect of a geriatric consultation service on management of patients in an acute care hospital.

Elderly patients present particular management challenges. We conducted a randomized clinical trial of the effect of a geriatric consultation service on the management of elderly patients in an acute care hospital. A total of 113 patients aged 75 years or more who met certain criteria were assigned to either receive (57 patients) or not receive (56) care by the service. At the end of their hospital stay the patients were assessed with regard to predetermined outcomes. The patients were followed up for 1 year after discharge to determine death rates and direct health care expenditures. The intervention group showed significantly greater improvement in mental status (p less than 0.01), were receiving fewer medications at discharge (p less than 0.05) and had lower short-term death rates (p less than 0.05) than the control group. A geriatric consultation service can improve the hospital care and health of the elderly.     

Excess mortality among children discharged from hospital after treatment for diarrhoea in rural Bangladesh.

Five hundred and fifty one children aged between 3 months and 3 years were followed up at home for 12 months after treatment of diarrhoea in a rural treatment centre of the International Centre for Diarrhoeal Disease Research, Bangladesh. During follow up the children were found to have a significantly higher mortality than generally observed in the community. The first three months after discharge appeared to be crucial, some 70% of the deaths occurring in that period. Severely malnourished children (nutritional state below 56% of the American National Center for Health Statistics (NCHS) standard of weight for age ratio) had a risk of death 14 times that of their well nourished counterparts (nutritional state 66% or more of the NCHS standard). The highest mortality occurred in 2 year olds, one in three of the severely malnourished children dying compared with one in 10 of the moderately malnourished. This pattern was not seen in children aged under 2 years. Immediate priority should be given to providing nutritional rehabilitation for malnourished children who contract diarrhoea.     

A geriatric day hospital: the Sunnybrook experience.

A review of the first 7 years of experience with the geriatric day hospital at Sunnybrook Medical Centre in Toronto revealed the following about the patients attending the day hospital during that time: most were 60 to 79 years old; over 85% attended 1 or 2 days a week; more than two thirds lived with a spouse or relatives; and more than half had diseases of the circulatory system or mental disorders. The day hospital offers a varied therapeutic program while easing the demands on the energy and time of the patient''s spouse or family and thus helps the elderly to remain in the community rather than live in an institution. The experience at Sunnybrook has shown that geriatric day hospitals can be a valuable component of the broad spectrum of integrated services and programs that must be developed to provide adequate health care for the growing number of older people in our population.
