RESUMEN

BACKGROUND: For older adults, a good transition from hospital to the primary or long-term care setting can decrease readmissions. This paper presents the 6-month post-discharge healthcare utilization of older adults and describes the numbers of readmissions and deaths for the most frequently occurring aftercare arrangements as a starting point in optimizing the post-discharge healthcare organization. METHODS: This cross-sectional study included older adults insured with the largest Dutch insurance company. We described the utilization of healthcare within 180 days after discharge from their first hospital admission of 2015 and the most frequently occurring combinations of aftercare in the form of geriatric rehabilitation, community nursing, long-term care, and short stay during the first 90 days after discharge. We calculated the proportion of older adults that was readmitted or had died in the 90-180 days after discharge for the six most frequent combinations. We performed all analyses in the total group of older adults and in a sub-group of older adults who had been hospitalized due to a hip fracture. RESULTS: A total of 31.7% of all older adults and 11.4% of the older adults with a hip fracture did not receive aftercare. Almost half of all older adults received care of a community nurse, whereas less than 5% received long-term home care. Up to 18% received care in a nursing home during the 6 months after discharge. Readmissions were lowest for older adults with a short stay and highest in the group geriatric rehabilitation + community nursing. Mortality was lowest in the total group of older aldults and subgroup with hip fracture without aftercare. CONCLUSIONS: The organization of post-discharge healthcare for older adults may not be organized sufficiently to guarantee appropriate care to restore functional activity. Although receiving aftercare is not a clear predictor of readmissions in our study, the results do seem to indicate that older adults receiving community nursing in the first 90 days less often die compared to older adults with other types of aftercare or no aftercare. Future research is necessary to examine predictors of readmissions and mortality in both older adult patients discharged from hospital.

RESUMEN

BACKGROUND: Elderly patients with cognitive impairment have a limited life expectancy and are often acutely admitted to the hospital. Hospitalization can negatively affect their quality of life. More knowledge on considerations prior to these referrals is needed to improve care for these patients. AIM: The aim of this research is to describe the aspects that can relate to the process of referring to the hospital in the acute situation by GPs in the case of elderly patients with cognitive impairment. METHOD: Semi-structured interviews with 21 GPs from The Netherlands were conducted and afterwards transcribed verbatim. From these transcripts categories were extracted by using 131 focused codes according to the grounded theory. RESULTS: Twelve categories were constructed. Six categories relate to whether it is desirable to treat or refer. These are the illness itself, the patient's wishes, the condition of the patient, the patient's burden, the possibilities in the hospital, and the vision of the GP. Six categories relate to the options available to the GP. These include medical options, care options, available time and information, the support available to the GP, and referrals without involvement of the GP. CONCLUSION: The referral of elderly patients with cognitive impairment is a complex process that is influenced by different types of factors. With these findings, specialists in hospitals, GPs, and policy makers can improve the quality of care for this group.

RESUMEN

BACKGROUND: Delirium is a common neuropsychiatric syndrome with considerable heterogeneity in clinical profile. Rapid reliable identification of clinical subtypes can allow for more targeted research efforts. METHODS: We explored the concordance in attribution of motor subtypes between the Delirium Motor Subtyping Scale 4 (DMSS-4) and the original Delirium Motor Subtyping Scale (DMSS) (assessed cross-sectionally) and subtypes defined longitudinally using the Delirium Symptom Interview (DSI). RESULTS: We included 113 elderly patients developing DSM-IV delirium after hip-surgery [mean age 86.9 ± 6.6 years; range 65-102; 68.1% females; 25 (22.1%) had no previous history of cognitive impairment]. Concordance for the first measurement was high for both the DMSS-4 and original DMSS (k = 0.82), and overall for the DMSS-4 and DSI (k = 0.84). The DMSS-4 also demonstrated high internal consistency (McDonald's omega = 0.90). The DSI more often allocated an assessment to "no subtype" compared to the DMSS-4 and DMSS-11, which showed higher inclusion rates for motor subtypes. CONCLUSIONS: The DMSS-4 provides a rapid method of identifying motor-defined clinical subtypes of delirium and appears to be a reliable alternative to the more detailed and time-consuming original DMSS and DSI methods of subtype attribution. The DMSS-4, so far translated into three languages, can be readily applied to further studies of causation, treatment and outcome in delirium.

RESUMEN

BACKGROUND: Different forms of case management for dementia have emerged over the past few years. In the COMPAS study (Collaborative dementia care for patients and caregivers study), two prominent Dutch case management forms were studied: the linkage and the integrated care form. AIM OF STUDY: Evaluation of the (cost)effectiveness of two dementia case management forms compared to usual care as well as factors that facilitated or impeded their implementation. METHODS: A mixed methods design with a) a prospective, observational controlled cohort study with 2 years follow-up among 521 dyads of people with dementia and their primary informal caregiver with and without case management; b) interviews with 22 stakeholders on facilitating and impeding factors of the implementation and continuity of the two case management models. Outcome measures were severity and frequency of behavioural problems (NPI) for the person with dementia and mental health complaints (GHQ-12) for the informal caregiver, total met and unmet care needs (CANE) and quality adjusted life years (QALYs). RESULTS: Outcomes showed a better quality of life of informal caregivers in the integrated model compared to the linkage model. Caregivers in the control group reported more care needs than those in both case management groups. The independence of the case management provider in the integrated model facilitated the implementation, while the rivalry between multiple providers in the linkage model impeded the implementation. The costs of care were lower in the linkage model (minus 22 %) and integrated care model (minus 33 %) compared to the control group. CONCLUSION: The integrated care form was (very) cost-effective in comparison with the linkage form or no case management. The integrated care form is easy to implement.

RESUMEN

OBJECTIVE: To describe the effect of implementation of a rapid response system on the composite endpoint of cardiopulmonary arrest, unplanned ICU admission, or death. DESIGN: Pragmatic prospective Dutch multicenter before-after trial, Cost and Outcomes analysis of Medical Emergency Teams trial. SETTING: Twelve hospitals participated, each including two surgical and two nonsurgical wards between April 2009 and November 2011. The Modified Early Warning Score and Situation-Background-Assessment-Recommendation instruments were implemented over 7 months. The rapid response team was then implemented during the following 17 months. The effects of implementing the rapid response team were measured in the last 5 months of this period. PATIENTS: All patients 18 years old and older admitted to the study wards were included. MEASUREMENTS AND MAIN RESULTS: In total, 166,569 patients were included in the study representing 1,031,172 hospital admission days. No differences were observed in patient demographics between periods. The composite endpoint of cardiopulmonary arrest, unplanned ICU admission, or death per 1,000 admissions was significantly reduced in the rapid response team versus the before phase (adjusted odds ratio, 0.847; 95% CI, 0.725-0.989; p = 0.036). Cardiopulmonary arrests and in-hospital mortality were also significantly reduced (odds ratio, 0.607; 95% CI, 0.393-0.937; p = 0.018 and odds ratio, 0.802; 95% CI, 0.644-1.0; p = 0.05, respectively). Unplanned ICU admissions showed a declining trend (odds ratio, 0.878; 95% CI, 0.755-1.021; p = 0.092), whereas severity of illness at the moment of ICU admission was not different between periods. CONCLUSIONS: In this study, introduction of nationwide implementation of rapid response systems was associated with a decrease in the composite endpoint of cardiopulmonary arrests, unplanned ICU admissions, and mortality in patients in general hospital wards. These findings support the implementation of rapid response systems in hospitals to reduce severe adverse events.

RESUMEN

In particular in (very) old patients other comorbidities may cover symptoms evoked by polymyalgia rheumatica (PMR). By describing three different patients we show that the diagnosis PMR should be considered in the elderly when symptoms are atypical for those belonging to the comorbidity. PMR is an invalidating disease that rapidly reacts to prednisone. Doctors delay results in a later start with adequate treatment. Side effects of pain medication and loss of mobility can be prevented by starting early with adequate treatment.

RESUMEN

BACKGROUND/AIMS: Catechol-O-methyltransferase, encoded by the COMT gene, is one of the enzymes that degrade dopamine. The aim of this study was to investigate whether polymorphisms in the COMT gene were associated with delirium. METHODS: Patients aged 65 years and older, acutely admitted to the medical department or to the surgical department following hip fracture, were included. rs4680, rs4818, and rs6269 were genotyped. RESULTS: Delirious patients were older, and more frequently had preexisting functional or cognitive impairment (p < 0.001). Polymorphisms in the COMT gene were not associated with the development of delirium. CONCLUSION: Although the COMT gene is a promising candidate gene for delirium in the elderly, functional genetic variations were not associated with delirium.

RESUMEN

In independent studies delirium was associated with higher levels of cortisol, interleukin(IL)s, and S100B. The aim of this study was to simultaneously compare cortisol, IL-6, IL-8, and S100B levels in patients aged 65years and older admitted for hip fracture surgery with and without delirium. Cortisol, IL-6, IL-8, and S100B were assayed in repeated blood samples. 120 patients (mean age 84years, 62 patients with delirium) were included. Highest levels of IL-8 (27.1, 95% Confidence Interval (CI): 13.6-53.1pg/ml) and cortisol (666, 95% CI: 475-859nmol/L) were before delirium, but of IL-6 (84.3, 95% CI: 46.5-151.4pg/mL) and S100B (0.18, 95% CI: 0.12-0.24 microg/L) during delirium. In multivariable analysis cortisol, LogIL-6, and LogS100B were significantly associated with delirium, but adjusted for pre-existing cognitive impairment, only LogS100B remained significantly associated. Cortisol, IL-6 and S100B may have a role in the pathogenesis of delirium, but S100B is the strongest independent marker.

RESUMEN

Dopamine excess appears to be critical in the final common pathway of delirium. The aim of this study was to investigate whether genetic polymorphisms in three dopamine-related genes (the dopamine receptor 2 (DRD2), dopamine receptor 3 (DRD3), and the dopamine transporter (SLC6A3) gene) were associated with delirium. Patients aged 65 years and older acutely admitted to the medical department or to the surgical department following hip fracture were included. Delirium was diagnosed by the Confusion Assessment Method. Sixteen single nucleotide polymorphisms (SNPs) and one variable number of tandem repeats in the SLC6A3 gene, nine SNPs in the DRD2 gene, and six SNPs in the DRD3 gene were genotyped. Fifty percent of the 115 surgical patients and 34% of the 605 medical patients experienced delirium. Delirious patients were older and had more frequently pre-existing functional and cognitive impairment (P < 0.001). After correction for multiple testing, one SNP in the SLC6A3 gene (rs393795) was associated with reduced risk of delirium (P = 0.032). Adjusted for age, cognitive impairment, and functional impairment, three SNPs in the DRD2 gene and seven SNPs in the SLC6A3 gene were associated with delirium; none of these associations was significant after correction for multiple testing. Variations in the SLC6A3 gene and possibly the DRD2 gene were associated with delirium. Although validation of these results is needed our results support a role for the dopamine transporter and dopamine receptor 2 in the pathogenesis of delirium.

RESUMEN

Delirium is the most common neuropsychiatric syndrome in elderly ill patients. Previously, associations between delirium and the dopamine transporter gene (solute carrier family 6, member 3 (SLC6A3)) and dopamine receptor 2 gene (DRD2) were found. The aim of this study was to validate whether markers of the SLC6A3 and DRD2 genes are were associated with delirium in independent populations. Six European populations collected DNA of older delirious patients. Associations were determined per population and results were combined in a meta-analysis. In total 820 medical inpatients, 185 cardiac surgery patients, 134 non-cardiac surgery patients and 502 population-based elderly subjects were included. Mean age was 82 years (SD 7.5 years), 598 (36%) were male, 665 (41%) had pre-existing cognitive impairment, and 558 (34%) experienced delirium. The SLC6A3 rs393795 homozygous AA genotype was more frequent in patients without delirium in all populations. The meta-analysis showed an Odds Ratio (OR) for delirium of 0.4 (95% confidence interval (C.I.) 0.2-0.6, P = 0.0003) for subjects with AA genotype compared to the AG and GG genotypes. SLC6A3 marker rs1042098 showed no association with delirium. In meta-analysis the DRD2 rs6276 homozygous GG genotype showed an OR of 0.8 for delirium (95% C.I. 0.6-1.1, P = 0.24). When subjects were stratified for cognitive status the rs6276 GG genotype showed ORs of 0.6 (95% C.I. 0.4-1.0, P = 0.06) and 0.8 (95% C.I. 0.5-1.5, P = 0.51) for delirium in patients with and without cognitive impairment, respectively. In independent cohorts, a variation in the SLC6A3 gene and possibly the DRD2 gene were found to protect for delirium.

RESUMEN

The COVID-19 crisis has pressured hospital-based care for children with high-risk asthma as they have become deprived of regular clinical evaluations. However, COVID-19 also provided important lessons about implementing novel directions for care. Personalized eHealth technology, tailored to the individual and the healthcare system, could substitute elements of hospital care and facilitate early and appropriate medical anticipation in response to imminent loss of control. This perspective article discusses new approaches to the clinical, organizational, and scientific aspects of the use of eHealth technology in pediatric asthma care in times of COVID-19, as illustrated by a case report of an acute asthma exacerbation possibly caused by COVID-19 infection.

RESUMEN

OBJECTIVES: To determine a possible association between Apolipoprotein E (APOE)sigma4-allele and delirium in a large cohort and combining these current data with former studies in a meta-analysis. DESIGN: Combination of a new prospective cohort study and meta-analysis. SETTING: Medical department and orthopedic/traumatology department of University hospital from 2003 to 2007. PARTICIPANTS: A total of 656 patients aged 65 years and older acutely admitted with a medical diagnosis or after hip fracture. MEASUREMENTS: Confusion Assessment Method for delirium, Informant Questionnaire on Cognitive Decline-short form for predelirium global cognitive impairment, and Katz Index of Activities of Daily Living for functionality. APOE was genotyped by mass spectrometer. A meta-analysis was performed combining the current data with published studies analyzing the association between the APOE sigma4-allele and the delirium. RESULTS: : The 49% of the 76 surgical patients and 35% of the 580 medical patients experienced delirium. Delirious patients were significantly older (82 versus 77 years) and had more frequently functional (66% versus 26%) and cognitive impairment (86% versus 29%) than nondelirious patients. The odds ratio (OR) for delirium adjusted for age, cognitive, and functional impairment of sigma4 carriers compared with non-sigma4 carriers was 1.7 (95% confidence interval [CI]: 1.1-2.6). Four studies were added to the meta-analysis, which included 1,099 patients in total. The OR for delirium in the meta-analysis was 1.6 (95% CI: 0.9-2.7) of sigma4 carriers compared with non-sigma4 carriers. CONCLUSIONS: This study and meta-analysis suggest an association between delirium and the APOE sigma4 allele.

RESUMEN

OBJECTIVE: To determine the frequency and background of the use of assessment instruments for the Comprehensive Geriatric Assessment by clinical geriatricians and internists in geriatric medicine; the secondary aim was to make an inventory of the willingness to standardise the assessment instruments used. DESIGN: A descriptive questionnaire study. METHOD: In December 2016, we sent out a digital questionnaire (Survey Monkey) to all the hospitals in the Netherlands. Respondents were asked which instruments they used for specific domains of the Comprehensive Geriatric Assessment, what their choice of instruments was based on, if these instruments had added value, and if they were prepared to change the instruments they used. RESULTS: We received 66 responses (response: 82%). The most frequently-used instruments were: Mini Mental State Examination in combination with the clock drawing test (21%), Geriatric Depression Scale-15 (45%), Katz Index of Independence in Activities of Daily Living-6 (75%), Lawton and Brody (48%), Mini Nutritional Assessment(-short form) (outpatient; 56%) and Short Nutritional Assessment Questionnaire (inpatient: 36%), Experienced Burden Informal Care (46%), Charlson Comorbidity Index (35%), Timed Up and Go (76%), and the Safety Management System (VMS) fall risk question (21%). The most frequently used instruments were used in a large number of hospitals (35-97%).The variation of tests was the greatest in the domains of cognition, malnutrition, and mobility/physical functioning. Many respondents saw the added value of a consensus set of instruments (median: 70%; interquartile range (IQR): 50-86), and most were willing to change the instruments they use (median: 80%; IQR: 65-90). CONCLUSION: This inventory shows that the instruments used in most domains were reasonably uniform. Taking the willingness to change into account, a national set of basis instruments seems to be an achievable aim.

RESUMEN

Delirium is a common and serious acute neuropsychiatric syndrome with core features of inattention and cognitive impairment, and associated features including changes in arousal, altered sleep-wake cycle, and other changes in mental status. The main risk factors are old age, cognitive impairment, and other comorbidities. Though delirium has consistent core clinical features, it has a very wide range of precipitating factors, including acute illness, surgery, trauma, and drugs. The molecular mechanisms by which these precipitating factors lead to delirium are largely obscure. In this article, we attempt to narrow down some specific causal pathways. We propose a basic classification for the etiological factors: (a) direct brain insults and (b) aberrant stress responses. Direct brain insults are largely indiscriminate and include general and regional energy deprivation (e.g., hypoxia, hypoglycaemia, stroke), metabolic abnormalities (e.g., hyponatraemia, hypercalcaemia), and the effects of drugs. Aberrant stress responses are conceptually and mechanistically distinct in that they constitute adverse effects of stress-response pathways, which, in health, are adaptive. Ageing and central nervous system disease, two major predisposing factors for delirium, are associated with alterations in the magnitude or duration of stress and sickness behavior responses and increased vulnerability to the effects of these responses. We discuss in detail two stress response systems that are likely to be involved in the pathophysiology of delirium: inflammation and the sickness behavior response, and activity of the limbic-hypothalamic-pituitary-adrenal axis. We conclude by discussing the implications for future research and the development of new therapies for delirium.

RESUMEN

OBJECTIVES: To examine changes in motor subtype profile in individuals with delirium. DESIGN: Observational, longitudinal study; substudy of a multicenter, randomized controlled trial. SETTING: Departments of surgery and orthopedics, Academic Medical Center and Tergooi Hospital, the Netherlands. PARTICIPANTS: Elderly adults acutely admitted for hip fracture surgery who developed delirium according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, for 2 days or longer (n = 76, aged 86.4 ± 6.1, 68.4% female). MEASUREMENTS: Delirium Motor Subtype Scale (DMSS), Delirium Rating Scale R98 (DRS-R98), comorbidity, and function. RESULTS: Median delirium duration was 3 days (interquartile range 2.0 days). At first assessment, the hyperactive motor subtype was most common (44.7%), followed by hypoactive motor subtype (28.9%), mixed motor subtype (19.7%), and no motor subtype (6.6%). Participants with no motor subtype had lower DRS-R98 scores than those with the other subtypes (P < .001). The DMSS-defined motor subtype of 47 (61.8%) participants changed over time. Katz Index of Activities of Daily Living, Charlson Comorbidity Index, cognitive impairment, age, sex, and delirium duration or severity were not associated with change in motor subtype. CONCLUSION: Motor subtype profile was variable in the majority of participants, although changes that occurred were often related to changes from or to no motor subtype, suggesting evolving or resolving delirium. Changes appeared not be associated with demographic or clinical characteristics, suggesting that evidence from cross-sectional studies of motor subtypes could be applied to many individuals with delirium. Further longitudinal studies should be performed to clarify the stability of motor subtypes in different clinical populations.

RESUMEN

OBJECTIVE: Melatonin plays a major role in maintaining circadian rhythm. Previous studies showed that its secretion pattern and levels could be disturbed in persons with dementia, psychiatric disorders, sleep disorders or with cancer. Also ageing is a factor that could alter melatonin levels, although previous research provides contradicting results. As melatonin supplementation is increasingly applied in older persons as sleep medication, it is important to know if melatonin levels decrease in healthy ageing and/or secretion patterns change. The objective of this study is to determine physiological levels and secretion patterns of melatonin in healthy older people. METHODS: We performed a systematic review and searched PubMed and Embase for studies published between January 1st 1980 and October 5th 2015 that measured melatonin in healthy persons aged ≥65years. RESULTS: Nineteen studies were retrieved. The number of participants ranged from 5 to 60 per study. Melatonin was mostly measured by radioimmunoassay (RIA) and the number of measurements per 24hours varied from 1 to 96. Sixteen studies showed a secretion pattern with a clear peak concentration, mostly at 0200h or 0300h. Maximum concentrations varied greatly from 11.2 to 91.3pgml(-1). Maximum melatonin level in studies with participants mean aged 65-70years was 49.3pgml(-1) and in studies with participants mean aged ≥75years 27.8pgml(-1), p-value <0.001. CONCLUSION: Total melatonin production in 24hours seems not to change in healthy ageing, but the maximal nocturnal peak concentration of melatonin might decline. It is important to take this into account when prescribing melatonin supplementation to older people.

RESUMEN

BACKGROUND: Delirium is characterized by disturbances in circadian rhythm. Melatonin regulates our circadian rhythm. Our aim was to compare preoperative cerebrospinal fluid (CSF) melatonin levels in patients with and without postoperative delirium. METHODS: Prospective cohort study with hip fracture patients ≥ 65 years who were acutely admitted to the hospital for surgical treatment and received spinal anaesthesia. CSF was collected after cannulation, before administering anaesthetics. Melatonin was measured by radioimmunoassay (RIA). Data on delirium was obtained from medical and nursing records. Nurses screened every shift for delirium using the Delirium Observation Screening Scale (DOSS). If the DOSS was ≥3, a psychiatrist was consulted to diagnose possible delirium using the DSM-IV criteria. At admission, demographic data, medical history, and information on functional and cognitive status was obtained. RESULTS: Seventy-six patients met the inclusion criteria. Sixty patients were included in the analysis. Main reasons for exclusion were technical difficulties, insufficient CSF or exogenous melatonin use. Thirteen patients (21.7%) experienced delirium during hospitalisation. Baseline characteristics did not differ between patients with and without postoperative delirium. In patients with and without postoperative delirium melatonin levels were 12.88 pg/ml (SD 6.3) and 11.72 pg/ml (SD 4.5) respectively, p-value 0.47. No differences between patients with and without delirium were found in mean melatonin levels in analyses stratified for cognitive impairment or age. CONCLUSION: Preoperative CSF melatonin levels did not differ between patients with and without postoperative delirium. This suggests that, if disturbances in melatonin secretion occur, these might occur after surgery due to postoperative inflammation.

RESUMEN

OBJECTIVE: To determine the predictive value of safety management system (VMS) screening questions for falling, delirium, and mortality, as punt down in the VMS theme 'Frail elderly'. DESIGN: Retrospective observational study. METHOD: We selected all patients ≥ 70 years who were admitted to non-ICU wards at the Deventer Hospital, the Netherlands, for at least 24 hours between 28 March 2011 and 10 June 2011. On admission, patients were screened with the VMS instrument by a researcher. Delirium and falls were recorded during hospitalisation. Six months after hospitalisation, data on mortality were collected. RESULTS: We included 688 patients with a median age of 78.7 (range: 70.0-97.1); 50.7% was male. The sensitivity of the screening for delirium risk was 82%, the specificity 62%. The sensitivity of the screening for risk of falling was 63%, the specificity 65%. Independent predictors for mortality within 6 months were delirium risk (odds ratio (OR): 2.3; 95% CI 1.1-3.2), malnutrition (OR: 2.1; 95% CI 1.3-3.5), admission to a non-surgical ward (OR: 3.0; 95% CI 1.8-5.1), and older age (OR: 1.1; 95%CI 1.0-1.1). Patients classified by the VMS theme 'Frail elderly' as having more risk factors had a higher risk of dying (p < 0.001). CONCLUSIONS: The VMS screening for delirium is a reasonably reliable instrument for identifying those elderly people with a high risk of developing this condition; the VMS sensitivity for fall risk is moderate. The number of positive VMS risk factors correlates with mortality and may therefore be regarded as a measure of frailty.

RESUMEN

BACKGROUND: Recent studies have shown that an increased bleeding tendency can be caused by Selective Serotonin Reuptake Inhibitors (SSRI) use. We aimed to investigate the occurrence and risk of blood transfusion in SSRI users compared to non-SSRI users in a cohort of patients admitted for hip-surgery. METHODS: We conducted a retrospective cohort study of patients who underwent planned or emergency hip surgery from 1996 to 2011 in the Academic Medical Center in Amsterdam. Primary outcome measure was risk of blood transfusion. Secondary outcome measures were pre- and postoperative hemoglobin level. Multivariate logistic regression was used to adjust for potential confounders. RESULTS: One-hundred and fourteen SSRI users were compared to 1773 non-SSRI users. Risk of blood transfusion during admission was increased for SSRI users in multivariate analyses (OR 1.7 [95% CI 1.1-2.5]). Also, pre-operative hemoglobin levels were lower in SSRI users (7.8 ± 1.0 mmol/L) compared to non-SSRI users (8.0 ± 1.0 mmol/L) (p  =  0.042)), as were postoperative hemoglobin levels (6.2 ± 1.0 mmol/L vs. 6.4 ± 1.0 mmol/L respectively) (p  =  0.017)). CONCLUSIONS: SSRI users undergoing hip surgery have an increased risk for blood transfusion during admission, potentially explained by a lower hemoglobin level before surgery. SSRI use should be considered as a potential risk indicator for increased blood loss in patients admitted for hip surgery. These results need to be confirmed in a prospective study.
