Outbreak of COVID-19 at three nursing homes in Bergen. / Utbrudd av covid-19 ved tre sykehjem i Bergen.

BACKGROUND: Nursing home residents are generally old and frail, and at high risk that COVID-19 will take a serious course. Outbreaks of COVID-19 have not previously been described in Norway, and it is important to identify mechanisms for spread of the infection and course of disease for nursing home residents with this pandemic disease. MATERIAL AND METHOD: We included residents from three nursing homes with outbreaks of COVID-19 in a retrospective observational study, and we retrieved information on the number of staff for whom SARS-CoV-2 was confirmed or who were placed in quarantine. We present resident characteristics, course of disease and mortality associated with COVID-19 in the nursing homes, as well as providing a brief description of the outbreaks. RESULTS: Forty residents were included, 26 of whom were women. The average age was 86.2 years. Thirty-seven of the residents had atypical symptoms, nine of them were asymptomatic at the time of diagnosis, and 21 died during the coronavirus infection. Contact tracing indicated that the outbreaks may have originated from staff in the pre-symptomatic or early and mild phase of the disease. SARS-CoV-2 was detected in forty-two staff members, and a further 115 were placed in quarantine. INTERPRETATION: Many residents had atypical disease presentation, and the mortality from COVID-19 was high. Spread of infection may have originated from staff, also before they displayed obvious symptoms, and contributed to extensive spread of SARS-CoV-2 in the three nursing homes.

No association between subnormal serum vitamin B12 and anemia in older nursing home patients.

PURPOSE: Since evidence of an association between vitamin B12 (B12) deficiency and anemia in older people is limited and inconclusive, we wanted to investigate this association in old, frail nursing home patients. METHODS: The study includes patients admitted to short-term, post-acute care (n = 765) and residents in long-term care (LTC) (n = 1665), in the municipality of Bergen. Anemia was defined according to the WHO criteria: Hb < 13 g/dL in men and < 12 g/dL in women, and as Hb < 11 g/dL, in both sex (moderate/severe anemia). The presence of anemia was analyzed in patients with subnormal (< 250 pmol/L), normal (250-650 pmol/L) and high (> 650 pmol/L) B12, and the association between anemia and clinical parameters, and including B12, was analyzed using logistic regression models. The use of B12 supplementation was investigated in the LTC patients. RESULTS: Mean age of the 2430 patients was 86 ± 7 years. WHO-defined anemia was seen in 1023 (42%), and moderate/severe anemia in 384 (16%) of the patients. In multiple logistic regression analyses, we found no statistically significant associations of subnormal B12 with WHO-defined anemia or moderate/severe anemia. Renal insufficiency, iron deficiency and CRP > 10 mg/L were significantly associated with both types of anemia, (p < 0.001). Among the LTC residents, 405 (24%) received B12 supplements, 112 (7%) of them had elevated B12 > 650 pmol/L. CONCLUSION: In older nursing home patients, no association was observed between subnormal B12 and anemia. Older patients in Western societies with mild/moderate anemia should not be treated with B12 supplements without further investigation.

Trends in psychotropic drug prescribing in Norwegian nursing homes from 1997 to 2009: a comparison of six cohorts.

BACKGROUND: Psychotropic drugs are extensively prescribed for the treatment of neuropsychiatric symptoms, despite modest efficacy and severe side effects. AIMS: We examined trends in psychotropic drug prescribing in Norwegian nursing homes from 1997 to 2009, in order to gain insight in practice development. METHODS: The study is a secondary data analysis of six cross-sectional nursing home studies conducted between 1997 and 2009. Patients aged >65 years were included. We compared the prevalence of psychotropic drugs (antipsychotics, anxiolytics, hypnotics, and antidepressants). Associations between prescription of psychotropics, and patients' age, gender, type of ward, and year of data collection were examined by univariate analysis and logistic regression. RESULTS: Altogether, 7 661 patients (mean age 85.2 years, 72.6% women) were included. Prevalence of all psychotropic drugs combined increased from 57.6% to 70.5%, anxiolytics from 14.9% to 21.9%, hypnotics from 14.5% to 22.9%, and antidepressants from 31.5% to 50.9%. Prevalence of antipsychotics varied between extremes 21.1% and 25.6%. Less prescribing of older drugs was exceeded by an increase in newer drug types. Concomitant prescribing of two or more psychotropic drugs increased from 21% to 33%. Predictors of psychotropic drugs were female gender (except antipsychotics), as well as age <80 years, and residency in special care units (except hypnotics). CONCLUSIONS: Prescribing of psychotropic drugs in nursing homes has increased considerably, especially regarding antidepressants. Explanations for this trend need to be further explored.

Psychoactive drugs in seven nursing homes.

AIMS: We wanted to pinpoint any differences in treatment between participating nursing homes, investigate which drugs are currently prescribed most frequently for long-term patients in nursing homes, estimate prevalence of administration for the following drug groups: neuroleptics, antidepressants, antidementia agents, opioids and the neuroleptics/anti-Parkinson's drug combination, and study comorbidity correlations. We also wanted to study differences in the administration of medications to patients with reduced cognitive functions in relation to those with normal cognition. METHODS: Information about 513 patients was collected from seven nursing homes in the city of Bergen, Norway, during the period March-April 2008. This consisted of copying personal medication records, weighing, recording the previous weight from records, electrocardiography, anamnestic particulars of any stroke suffered, recording if there is cognitive impairment or not and analyzing a standardized set of blood samples. RESULTS: Considerable treatment differences existed between nursing homes, both percentage patients and Defined Daily Dosages. Patients with reduced cognitive functions were prescribed less drugs in general, except neuroleptics. Of all patients, 41.5% were given antidepressants, 24.4% neuroleptics, 22.0% benzodiazepines, 8.0% anticholinesterases and 5.0% memantine. The ratio of traditional to atypical neuroleptics was 122:23. In all, 30.0% of the patients taking neuroleptics were on more than one drug and 35.0% of the patients had opioids by way of regular or as-needed drugs, ratio 14.6%:28.7%. Of 146 patients on neuroleptics, five patients had anti-Parkinson's drugs too. The average use of regular drugs for patient with intact cognition was 7.1 drugs, and for patients with reduced cognitive functions 5.7 drugs. CONCLUSIONS: There are differences in treatment with psychoactive drugs between nursing homes. Patients with reduced cognitive functions receive less cardiovascular drugs than patients with normal cognition. The reason for this still remains unclear. Improvement strategies are needed. The proportion of patients per institution on selected drugs can serve as a feedback parameter in quality systems.

Hospital admissions from nursing homes: rates and reasons.

Hospital admissions from nursing homes have not previously been investigated in Norway. During 12 months all hospital admissions (acute and elective) from 32 nursing homes in Bergen were recorded via the Norwegian ambulance register. The principal diagnosis made during the stay, length of stay, and the ward were sourced from the hospital's data register and data were merged. Altogether 1,311 hospital admissions were recorded during the 12 months. Admissions from nursing homes made up 6.1% of the total number of admissions to medical wards, while for surgical wards they made up 3.8%. Infections, fractures, cardiovascular and gastri-related diagnoses represented the most frequent admission diagnoses. Infections accounted for 25.0% of admissions, including 51.0% pneumonias. Of all the admissions, fractures were the cause in 10.2%. Of all fractures, hip fractures represented 71.7. The admission rate increased as the proportion of short-term beds increased, and at nursing homes with short-term beds, admissions increased with increasing physician coverage. Potential reductions in hospitalizations for infections from nursing homes may play a role to reduce pressure on medical departments as may fracture prevention. Solely increasing physician coverage in nursing homes will probably not reduce the number of hospitalizations.

Can electronic tools help improve nursing home quality?

Background. Nursing homes face challenges in the coming years due to the increased number of elderly. Quality will be under pressure, expectations of the services will rise, and clinical complexity will grow. New strategies are needed to meet this situation. Modern clinical information systems with decision support may be part of that. Objectives. To study the impact of introducing an electronic patient record system with decision support on the use of warfarin, neuroleptics and weighing of patients, in nursing homes. Methods. A prevalence study was performed in seven nursing homes with 513 subjects. A before-after study with internal controls was performed. Results. The prevalence of atrial fibrillation in the seven nursing homes was 18.8%. After intervention, the proportion of all patients taking warfarin increased from 3.0% to 9.8% (P = 0.0086), neuroleptics decreased from 33.0% to 21.5% (P = 0.0121), and the proportion not weighed decreased from 72.6% to 16.0% (P < 0.0001). The internal controls did not change significantly. Conclusion. Statistics and management data can be continuously produced to monitor the quality of work processes. The electronic health record system and its system for decision support can improve drug therapy and monitoring of treatment policy.

Acute hospital admissions among nursing home residents: a population-based observational study.

BACKGROUND: Nursing home residents are prone to acute illness due to their high age, underlying illnesses and immobility. We examined the incidence of acute hospital admissions among nursing home residents versus the age-matched community dwelling population in a geographically defined area during a two years period. The hospital stays of the nursing home population are described according to diagnosis, length of stay and mortality. Similar studies have previously not been reported in Scandinavia. METHODS: The acute hospitalisations of the nursing home residents were identified through ambulance records. These were linked to hospital patient records for inclusion of demographics, diagnosis at discharge, length of stay and mortality. Incidence of hospitalisation was calculated based on patient-time at risk. RESULTS: The annual hospital admission incidence was 0.62 admissions per person-year among the nursing home residents and 0.26 among the community dwellers. In the nursing home population we found that dominant diagnoses were respiratory diseases, falls-related and circulatory diseases, accounting for 55% of the cases. The median length of stay was 3 days (interquartile range = 4). The in-hospital mortality rate was 16% and 30 day mortality after discharge 30%. CONCLUSION: Acute hospital admission rate among nursing home residents was high in this Scandinavian setting. The pattern of diagnoses causing the admissions appears to be consistent with previous research. The in-hospital and 30 day mortality rates are high.

[Electronic medical records should be structured]. / Elektroniske pasientjournaler bør vaere strukturerte.

BACKGROUND: Use of information technology in the health services has not resulted in the benefits hoped for. An important prerequisite for success may be to structure electronic medical records. Is this assumption research-based? MATERIAL AND METHODS: PubMed was searched via Endnote. The search words "medical record (any field) + structured (any field)" resulted in 843 hits and "electronic decision support (any field)" resulted in 824. Titles and abstracts were used to identify relevant articles; titles identified 103 articles and abstracts 70. RESULTS: Research shows that structured electronic medical records can result in quicker data entry, improved quality and records that are useful in daily clinical work. Doctors and nurses prefer structured data entry; electronic nursing records are better and databases with structured electronic patient records can be used on a large scale to develop treatment regimes and quality assurance. Clinical decision support systems integrated into electronic medical records can provide positive cost-effectiveness. Most doctors and nurses understand the importance of such systems. INTERPRETATION: Structured data entry seems to be an important element in successful electronic medical record systems.

Clinically important renal impairment in various groups of old persons.

OBJECTIVE: To assess renal function in various groups of elderly persons, and to determine the proportion of patients with clinically important renal impairment. DESIGN: Cross-sectional study. PARTICIPANTS: Three geriatric populations aged 70 years and over, representing increasing levels of care/treatment: community-dwelling elderly referred to a geriatric outpatient department, inpatients on a geriatric ward, and nursing home patients. MAIN OUTCOME MEASURES: Cockroft and Gault's formula was applied to calculate glomerular filtration rate (GFR). Differences in GFR between age groups and between care levels were explored. RESULTS: Altogether 288 elderly persons were included in the study. We observed a general age-related decline of renal function. Only 2% of the participants had normal renal function (GFR >90 ml/min), 13% had light (GFR 60-89 ml/min), 68% moderate (GFR 30-59 ml/min), and 17% severe (GFR 15-29 ml/min) impairment in GFR. Moderate or severely decreased GFR was observed in 75% of the outpatients, 78% of the patients from the geriatric ward, and 91% of the nursing home patients. Altogether 99% of patients aged 85+ had renal impairment necessitating dosing adjustment for drugs that are mainly eliminated through renal excretion. CONCLUSION: Clinically important renal impairment is common in old age, especially in the frailest elderly living in nursing homes. This finding underlines the necessity for close supervision of drug treatment based on renal function in old age.
