Demographic and clinical factors associated with same-day discharge and unplanned readmission following shoulder arthroplasty: a retrospective cohort study / 대한마취과학회지

Background@#Same-day discharge, defined as discharge from the hospital within 24 h of surgery, has been shown to be safe for joint arthroplasty. We examined demographic and clinical factors associated with same-day discharge and unplanned readmission following shoulder arthroplasty in adult patients. @*Methods@#Utilizing data from the American College of Surgeons National Surgical Quality Improvement Program database, we extracted information of all patients that underwent shoulder arthroplasty. The primary and secondary outcome of interest was same-day discharge and 30-day unplanned readmission, respectively. We utilized multivariable logistic regression to identify covariates associated with these outcomes. @*Results@#There were 17,011 patients analyzed when identifying predictors for same-day discharge. There was an increase in same-day discharge from 2007 to 2016. The odds of same-day discharge were significantly better for males (P < 0.001). The odds of same-day discharge was significantly decreased for every 10-year increase in age and for patients with insulin dependent diabetes, poor functional status, chronic obstructive pulmonary disease, congestive heart failure, bleeding disorder, and comorbidity burden (all P < 0.001). There were 14,276 patients analyzed for hospital readmission. The odds of unplanned readmission were significantly higher for every 10-year increase in age and for patients with poor functional status, congestive heart failure, bleeding disorder, and higher comorbidity burden (all P < 0.001). @*Conclusions@#The results of this study show that preoperative comorbidities and advanced age reduce the odds of same-day discharge. Risk stratification, preoperative optimization, and coordinated care after surgery may be helpful to optimize patients for same-day discharge.

Change in psychotropic drug use in Norwegian nursing homes between 2004 and 2011.

ABSTRACTBackground:We aimed to assess whether there were any changes in the use of psychotropic drugs in Norwegian nursing homes between 2004 and 2011. Also, we investigated whether the predictors of use of specific psychotropic drug groups have changed. METHODS: We conducted a secondary analysis of two cohort studies of two Norwegian nursing home samples (2004/05 and 2010/11). Multivariate models were applied. RESULTS: We found a significant decrease in the prescription of antipsychotic drugs between 2004 and 2011 (0.63 OR, 95%CI = 0.49-0.82, p < 0.001) even after adjusting for relevant demographic and clinical variables. There are only minor changes for the other psychotropic drugs. We found that (1) the use of specific psychotropic drug groups as well as the number of psychotropic drugs used was associated with more affective symptoms and (2) the use of specific psychotropic drug groups as well as the number of psychotropic drugs used was associated with lower scores on the Physical Self-Maintenance scale. CONCLUSION: This is the first study to show a robust decrease in antipsychotic drug use in nursing home patients with dementia unrelated to possible changes in case mix. The change might be explained by treatment recommendations against its use except in the most severe conditions of aggression or psychosis. Our findings indicate that it takes several years to implement scientific knowledge in clinical practice in nursing homes.

Use of hormonal contraceptives among immigrant and native women in Norway: data from the Norwegian Prescription Database.

OBJECTIVE: To examine the use of hormonal contraceptives among immigrant and native women in Norway. DESIGN: Nationwide registry-based study based on merged data from the Norwegian Prescription Database, the Norwegian Population Registry, the Regular General Practitioner Database and the Medical Birth Registry. SETTING: Norway. SAMPLE: All women born abroad to two foreign-born parents (immigrants), or born in Norway to two Norwegian-born parents (natives) aged 16-45 years, who lived in Norway in 2008. METHODS: Data on all collected supplies of hormonal contraceptives in 2008 were merged with demographic, socio-economic and immigration data, information on any delivery and women's general practitioners. MAIN OUTCOME MEASURES: User rates of hormonal contraception and predictors of contraceptive use. RESULTS: A total of 893,073 women were included, of whom 130,080 were immigrants. More native women (38%) used hormonal contraceptives compared with all immigrant groups (15-24%). The odds ratios for any use of hormonal contraceptives for immigrants compared with Norwegian-born women were; Nordic countries 0.53, South and Central America 0.53, Western countries 0.39, Asia 0.30, Eastern Europe 0.29, Africa 0.29. Work, education, long stay in Norway and young age of immigration predicted the use of hormonal contraceptives among immigrants. CONCLUSIONS: The use of hormonal contraceptives varies between natives and immigrant groups. Further work is needed to ascertain whether these differences can be explained by higher desires for fertility, preferential use of non-hormonal contraceptives or other reasons identified through qualitative research.

Initial prescription of antipsychotics and antidepressants in general practice and specialist care in Norway.

OBJECTIVE: To examine the incidence rates of antipsychotic (AP) and antidepressant (AD) drug treatment in Norway and the proportions initiated in general practice and specialist care respectively. METHOD: Data on all prescriptions of APs and ADs dispensed to the general population in Norway from 1 January 2004 until 31 August 2009 were extracted from the Norwegian Prescription Database. This information was merged with data about general practitioners (GPs) from the Norwegian Regular General Practitioner Scheme. RESULTS: One-year incidence rates per 1000 inhabitants were 3.4 for APs and 8.6 for ADs. GPs initiated 58% of APs and 73% of ADs, while psychiatrists initiated 15% and 6% respectively. Psychiatrists initiated treatment more often among younger patients, and they prescribed relatively newer drugs more commonly than GPs. A large share of incident users did not refill their prescriptions for APs (57%) or ADs (33%). CONCLUSION: GPs have a key role as regards initiating treatment with APs and ADs in Norway, while psychiatrists' influence seems limited, particularly among older patients. Efforts for quality improvement of mental health care need to involve primary health care. In addition, an increased focus from psychiatrists towards the increasingly ageing part of the population seems requisite.

Multidisciplinary medication review in nursing home residents: what are the most significant drug-related problems? The Bergen District Nursing Home (BEDNURS) study.

AIM: Based on a multidisciplinary review of drug use in nursing home residents, this study aimed to identify the most frequent clinically relevant medication problems and to analyse them according to the drugs involved and types of problems. METHODS: Cross sectional study auditing drug use by 1354 residents in 23 nursing homes in Bergen, Norway. Data were collected in 1997. A physician/pharmacist panel performed a comprehensive medication review with regard to indications for drug use and active medical conditions. The drug related problems were subsequently classified according to the drugs involved and types of problems (indication, effectiveness, and safety issues). RESULTS: 2445 potential medication problems were identified in 1036 (76%) residents. Psychoactive drugs accounted for 38% of all problems; antipsychotics were the class most often involved. Multiple psychoactive drug use was considered particularly problematic. Potential medication problems were most frequently classified as risk of adverse drug reactions (26%), inappropriate drug choice for indication (20%), and underuse of beneficial treatment (13%). CONCLUSIONS: Three of four nursing home residents had clinically relevant medication problems, most of which were accounted for by psychoactive drugs. The most frequent concerns were related to adverse drug reactions, drug choice, and probable undertreatment.

Psychotropic drug use in nursing homes--diagnostic indications and variations between institutions.

OBJECTIVE: Psychotropic drug use among nursing home residents with regard to diagnostic indications and patient- and institution characteristics was analysed. METHODS: A cross-sectional study of medication data from 1552 residents at 23 nursing homes in Bergen, Norway, was performed. Psychotropic drug use (neuroleptics, anxiolytics, hypnotics, antidepressants, and two sedative antihistamines) was analysed with regard to prevalence, diagnostic indications, duration of use, and general patient- and institution characteristics. RESULTS: Psychotropic drugs were taken on a daily schedule by 59% of all residents, most commonly as long-term treatment. Antidepressants (in 70% selective serotonin re-uptake inhibitors) were used by 31%, neuroleptics by 23%, and benzodiazepines by 22% of all the residents. Neuroleptics were given for non-psychotic behavioural and psychological symptoms in 66% of the cases. Sleeping disorders were most commonly treated with long-acting benzodiazepine hypnotics. Psychotropic drug use decreased with increasing patient age. Drug use patterns varied greatly between the different nursing homes: the prevalence of neuroleptic use varied from 0 to 61% of the residents, and antidepressant use varied from 10 to 63%. In nursing homes providing relatively more physician staff time, the residents were more likely to use antidepressants. CONCLUSIONS: Psychotropic drugs are used by a majority of nursing home residents as long-term symptomatic treatment. The great variations between the institutions can only to a small extent be explained by quantitative differences between the institutions.

[Mental impairment in nursing home residents]. / Mental svikt hos sykehjemspasienter.

BACKGROUND: Nursing homes are the corner stones in long-term institutional care for frail elderly people. Expansion and strengthening of community-based services during the last decade has enabled frail elderly who earlier would have moved into a nursing home to stay in their own home or in service apartments. MATERIAL AND METHODS: In a cross-sectional, anonymised study, changes in nursing homes in the city of Bergen between 1985 and 1996/97 were analysed with regard to prevalence of mentally impaired residents. The following items were assessed by nurses who were in daily contact with the residents: mental capacity by means of Clinical Dementia Rating (CDR), activities of daily living (ADL), and behaviour. The study population consisted of 1,296 residents from 21 institutions in 1985 and 1,141 residents from 16 institutions i 1996/97. RESULTS: The percentage of mentally impaired residents increased significantly, from 75 to 82, and the percentage of residents who were in need of extended nursing care rose from 87 to 91. The median duration of stay did not change significantly, but was reduced for residents with slight mental impairments (CDR 1), from 871 to 721 days. INTERPRETATION: Today, predominately mentally impaired and physically disabled elderly are cared for in general nursing homes. These are patients in need of continuous medical care and supervision, and do not fit into an ideology which "demedicalizes" severe medical conditions in old people. Both nursing homes and sheltered livings are needed.

Drug treatment of heart failure--do nursing-home residents deserve better?

OBJECTIVE: To describe and assess drug treatment of heart failure (HF) in nursing-home residents. DESIGN: Descriptive cross-sectional study. Individual patient information was obtained from the medical records and drug-dispensing cards. SETTING: Nursing homes in Bergen, Norway. MAIN OUTCOME MEASURES: Demographic data, diagnostic data (main diagnoses, diagnostic indications for the drugs used), medications (drugs, dosage and duration of use). RESULTS: Data were gathered from 23 of 27 obtainable institutions representing 1552 residents (86% of the Bergen nursing-home population); 469 (30%) of the residents used drugs for HF, the majority of whom (293 patients) were treated with furosemide only. Supplementary angiotensin-converting enzyme (ACE) inhibitors (predominantly in sub-target doses) were provided to 17% of the HF patients. About one out of four used drug combinations which we considered to be potentially harmful for HF patients. CONCLUSIONS: ACE inhibitors are probably under-utilised for HF in nursing-home residents. Potentially harmful drug combinations commonly occur. Both diagnosis and drug treatment for HF should be challenged in the nursing-home setting.

ELISA procedures for the measurement of IgG subclass antibodies to bacterial antigens.

We have developed enzyme-linked immunosorbent assays (ELISA) of IgG subclass antibodies against whole bacteria and bacterial antigens using enzyme-labelled mouse monoclonal antibodies. The properties of different anti-subclass antibodies were compared. In sera from 18 healthy adults we measured the IgG subclass distribution of specific antibodies against Staphylococcus aureus and Haemophilus influenzae b and against distinct bacterial components: pneumococcal capsular polysaccharides, dextran and tetanus toxoid. We found that antibodies against protein (tetanus toxoid) were mainly IgG1, with some contribution of IgG4 and IgG2. Antibodies against polysaccharides (pneumococcal PS and dextran) and whole bacteria were restricted mainly to IgG1 and IgG2.
