Exploring the validity of identifying care home residents through a new national register.

AIMS: Identifying permanent care home residents in Denmark by national registers is subject to error. The current register-based method has a sensitivity of 87% and a positive predictive value of 57%. The Danish National Health Data Authority has generated a new register named Care Home Data (in Danish: Plejehjemsdata) to increase the quality of register-based studies on care home residents. This study aimed to investigate the validity of Care Home Data. METHODS: We generated the gold standard by retrieving information from the four municipalities of Southern Jutland on all individuals living permanently in a care home facility in 2019. Care Home Data generates information on care home residents by pairing addresses of every apartment in Danish care home facilities with the addresses of Danish citizens. The agreement between Care Home Data and the gold standard was analysed by calculating the sensitivity and positive predictive value. RESULTS: According to the municipalities, a total of 2081 individuals resided permanently in care home facilities in Southern Jutland in 2019 (gold standard). Care Home Data identified 2128 permanent care home residents; of which 2019 individuals were identified by both the municipalities and Care Home Data (true positives); 62 individuals were not identified by Care Home Data (false negatives), and 109 individuals identified by Care Home Data did not appear in data from the municipalities (false positives). This gave a sensitivity of Care Home Data of 97.0% and a positive predictive value of 94.9%. CONCLUSIONS: Care Home Data is a much improved tool for identifying citizens permanently residing in care homes with very high sensitivity and positive predictive value.

Cross sectional study of multiresistant bacteria in Danish emergency departments: prevalence, patterns and risk factors for colonization (AB-RED project).

BACKGROUND: Multiresistant bacteria (MRB) is an increasing problem. Early identification of patients with MRB is mandatory to avoid transmission and to target the antibiotic treatment. The emergency department (ED) is a key player in the early identification of patients who are colonized with MRB. There is currently sparse knowledge of both prevalence and risk factors for colonization with MRSA, ESBL, VRE, CPE and CD in acutely admitted patients in Western European countries including Denmark. To develop evidence-based screening tools for identifying carriers of resistant bacteria among acutely admitted patients, systematic collection of information on risk factors and exposures is required. Since a geographical variation is suspected, it is desirable to include emergency departments across the country. The aim of this project is to provide a comprehensive overview of prevalence and risk factors for MRSA, ESBL, VRE, CPE and CD colonization in patients admitted to Danish ED's. The objectives are to describe the prevalence and demography of resistance, co-infections, to identify risk factors for carrier state and to develop and validate a screening tool for identification of carriers. METHODS: Multicenter descriptive and analytic cross-sectional survey from January-May 2018 of around 10.000 acutely admitted patients > 18 years in 8 EDs for carrier state and risk factors for antibiotic resistant bacteria. Information about the background and possible risk factors for carrier status together with swabs from the nose, throat and rectum is collected and analyzed for MRSA, ESBL, VRE, CPE and CD. The prevalence of the resistant bacteria are calculated at hospital level, regional level and national level and described with relation to residency, sex, age and risk factors. A screening model for identification of carrier stage of resistant bacteria is developed and validated. DISCUSSION: The study will provide the prevalence of colonized patients with resistant bacteria on arrival to the ED and variation in demographic patterns, and will develop a clinical tool to identify certain risk groups. This will enable the clinician to target antibiotic treatments and to reduce the in-hospital spreading of resistant bacteria. This knowledge is important for implementing and evaluating antimicrobial stewardships, screening and infection control strategies.

A prediction model to identify hospitalised, older adults with reduced physical performance.

BACKGROUND: Identifying older adults with reduced physical performance at the time of hospital admission can significantly affect patient management and trajectory. For example, such patients could receive targeted hospital interventions such as routine mobilisation. Furthermore, at the time of discharge, health systems could offer these patients additional therapy to maintain or improve health and prevent institutionalisation or readmission. The principle aim of this study was to identify predictors for persisting, reduced physical performance in older adults following acute hospitalisation. METHODS: This was a prospective cohort study that enrolled 117 medical patients, ages 65 or older, who were admitted to a short-stay unit in a Danish emergency department. Patients were included in the study if at the time of admission they performed ≤8 repetitions in the 30-s Chair-Stand Test (30s-CST). The primary outcome measure was the number of 30s-CST repetitions (≤ 8 or >8) performed at the time of follow-up, 34 days after admission. Potential predictors within the first 48 h of admission included: age, gender, ability to climb stairs and walk 400 m, difficulties with activities of daily living before admission, falls, physical activity level, self-rated health, use of a walking aid before admission, number of prescribed medications, 30s-CST, and the De Morton Mobility Index. RESULTS: A total of 78 (67%) patients improved in physical performance in the interval between admission and follow-up assessment, but 76 patients (65%) had persistent reduced physical performance when compared to their baseline (30s-CST ≤ 8). The number of potential predictors was reduced in order to create a simplified prediction model based on 4 variables, namely the use of a walking aid before hospitalisation (score = 1.5), a 30s-CST ≤ 5 (1.8), age > 85 (0.1), and female gender (0.6). A score > 1.8 identified 78% of the older adults who continued to have reduced physical performance following acute hospitalisation. CONCLUSION: At the time of admission, the variables of age, gender, walking aid use, and a 30s-CST score ≤ 5 enabled clinicians to identify 78% of older adults who had persisting reduced physical performance following acute hospitalisation.

Discharge from an emergency department observation unit and a surgical assessment unit: experiences of patients with acute abdominal pain.

AIMS AND OBJECTIVES: To investigate the experiences of patients with acute abdominal pain at discharge from an emergency department observation unit compared with discharge from a surgical assessment unit. BACKGROUND: The increase in emergency department observation units has increased short-term admissions and changed the patient journey from admission and discharge from specialised wards staffed by specialist nurses to admission and discharge from units staffed by emergency nurses. DESIGN: A comparative qualitative interview study. METHODS: The study included 20 patients: 10 from an emergency department observation unit and 10 from a surgical assessment unit, and took a phenomenological-hermeneutic approach. Patients were interviewed at discharge and three months later. RESULTS: More patients from the emergency department observation unit experienced readiness for discharge and had plans for follow-up, compared with patients from the surgical assessment unit. In the surgical assessment unit, more patients were readmitted, had unanswered questions after three months and experienced a follow-up visit at the general practitioner as insufficient. More patients from the surgical assessment unit reported receiving useful self-care advice, compared with those from the emergency department observation unit. CONCLUSION: The experience of emergency department observation unit patients on discharge and follow-up was that the health professionals were more supportive, compared with surgical assessment unit patients, who felt discharge occurred too early, but with more preparation for independent home self-care. These results are an important factor in the patient experience of discharge from hospital and may reflect differences in specialisation of the nurses. RELEVANCE TO CLINICAL PRACTICE: Units discharging patients with acute abdominal pain could be inspired by scheduled fast-track surgery programmes with structured information about admission, treatment and follow-up and easy access to relevant health professionals after discharge.

Perspectives of patients with acute abdominal pain in an emergency department observation unit and a surgical assessment unit: a prospective comparative study.

AIMS AND OBJECTIVES: To investigate the patient perspective when admitted with acute abdominal pain to an emergency department observation unit compared with the perspective when admitted to a surgical assessment unit. BACKGROUND: An increase in emergency department observation units has led to more short-term admissions and has changed the patient journey from admission to specialised wards staffed by specialist nurses to stays in units staffed by emergency nurses. DESIGN: A comparative field study. METHODS: The study included 21 patients. Participant observation and qualitative interviews were performed, and the analyses were phenomenological-hermeneutic. RESULTS: Emergency department observation unit patients had extensive interaction with health professionals, which could create distrust. Surgical assessment unit patients experienced lack of interaction with nurses, also creating distrust. Emergency department observation unit patients had more encounters with fellow patients than the surgical assessment unit patients did, which was beneficial when needing assistance, but disturbing when needing rest. The limited contact with other patients in the surgical assessment unit revealed the opposite effect. In both units, there was nonpersonalised care, making it difficult for patients to make informed decisions. CONCLUSION: The multibedded rooms in the emergency department observation unit had a positive influence on patient­nurse interaction, but a negative influence on privacy; the opposite was found in the surgical assessment unit with its rooms with fewer beds. The extensive professional­patient interactions in the emergency department observation unit created distrust. The limited professional­patient interaction in the surgical assessment unit did the same. That the emergency department observation unit was staffed by emergency nurses seemed to have a positive influence on the length of patient­nurse interactions, while the surgical assessment unit staffed by specialist nurses seemed to have the opposite effect. There was lack of information and personalised care in both units. RELEVANCE TO CLINICAL PRACTICE: Units receiving acute patients need to provide personalised care and information about how the unit functions and about care and treatment to improve the patients' ability to make decisions during admission.

Diagnostic Performance of Plasma SP-D, KL-6, and CC16 in Acutely Hospitalised Patients Suspected of Having Community-Acquired Pneumonia-A Diagnostic Accuracy Study.

Community-acquired pneumonia is a common cause of acute hospitalisation. Identifying patients with community-acquired pneumonia among patients suspected of having the disease can be a challenge, which causes unnecessary antibiotic treatment. We investigated whether the circulatory pulmonary injury markers surfactant protein D (SP-D), Krebs von den Lungen-6 (KL-6), and Club cell protein 16 (CC16) could help identify patients with community-acquired pneumonia upon acute admission. In this multi-centre diagnostic accuracy study, SP-D, KL-6, and CC16 were quantified in plasma samples from acutely hospitalised patients with provisional diagnoses of community-acquired pneumonia. The area under the receiver operator characteristics curve (AUC) was calculated for each marker against the following outcomes: patients' final diagnoses regarding community-acquired pneumonia assigned by an expert panel, and pneumonic findings on chest CTs. Plasma samples from 339 patients were analysed. The prevalence of community-acquired pneumonia was 63%. AUCs for each marker against both final diagnoses and chest CT diagnoses ranged between 0.50 and 0.56. Thus, SP-D, KL-6, and CC16 demonstrated poor diagnostic performance for community-acquired pneumonia in acutely hospitalised patients. Our findings indicate that the markers cannot readily assist physicians in confirming or ruling out community-acquired pneumonia.

Gram Stain and Culture of Sputum Samples Detect Only Few Pathogens in Community-Acquired Lower Respiratory Tract Infections: Secondary Analysis of a Randomized Controlled Trial.

Identification of the bacterial etiology of lower respiratory tract infections (LRTI) is crucial to ensure a narrow-spectrum, targeted antibiotic treatment. However, Gram stain and culture results are often difficult to interpret as they depend strongly on sputum sample quality. We aimed to investigate the diagnostic yield of Gram stain and culture from respiratory samples collected by tracheal suction and expiratory technique from adults admitted with suspected community-acquired LRTI (CA-LRTI). In this secondary analysis of a randomized controlled trial, 177 (62%) samples were collected by tracheal suction, and 108 (38%) by expiratory technique. We detected few pathogenic microorganisms, and regardless of sputum quality, there were no significant differences between the sample types. Common pathogens of CA-LRTI were identified by culture in 19 (7%) samples, with a significant difference between patients with or without prior antibiotic treatment (p = 0.007). The clinical value of sputum Gram stain and culture in CA-LRTI is therefore questionable, especially in patients treated with antibiotics.

Readmission trends before and after a national reconfiguration of emergency departments in Denmark.

OBJECTIVE: In order to achieve better and more efficient emergency health care, the Danish public hospital system has been reconfigured, with hospital emergency care being centralised into extensive and specialised emergency departments. This article examines how this reconfiguration has affected patient readmission rates. METHODS: We included all unplanned hospital admissions (aged ≥18 years) at public, non-psychiatric hospitals in four geographical regions in Denmark between 1 January 2007 and 24 December 2017. Using an interrupted time-series design, we examined trend changes in the readmission rates. In addition to analysing the overall effect, analyses stratified according to admission time of day and weekdays/weekends were conducted. The analyses were adjusted for patient characteristics and other system changes. RESULTS: The seven-day readmission rate increased from 2.6% in 2007 to 3.8% in 2017, and the 30-day rate increased from 8.1% to 11.5%. However, the rates were less than what they would have been had the reconfiguration not been introduced. The reconfiguration reduced the seven-day readmission rate by 1.4% annually (hazard ratio [CI 95%] 0.986 [0.981-0.991]) and the 30-day rate by 1% annually (hazard ratio [CI 95%] 0.99 [0.987-0.993]). CONCLUSIONS: Reconfiguration reduced the rate of increase in readmissions, but nevertheless readmissions still increased across the study period. It seems hospitals and policymakers will need to identify further ways to reduce patient loads.

Antibiotic Guideline Adherence at the Emergency Department: A Descriptive Study from a Country with a Restrictive Antibiotic Policy.

BACKGROUND: Denmark has a low level of antimicrobial resistance (AMR). Patients hospitalized with suspected infection often present with unspecific symptoms. This challenges the physician between using narrow-spectrum antibiotics in accordance with guidelines or broad-spectrum antibiotics to compensate for diagnostic uncertainty. The aim of this study was to investigate adherence to a restrictive antibiotic guideline for the most common infection in emergency departments (EDs), namely community-acquired pneumonia (CAP). METHOD: This multicenter descriptive cross-sectional study included adults admitted to Danish EDs with a suspected infection. Data were collected prospectively from medical records. RESULTS: We included 954 patients in the analysis. The most prescribed antibiotics were penicillin with beta-lactamase inhibitor at 4 h (307 (32.2%)), 48 h (289 (30.3%)), and day 5 after admission (218 (22.9%)). The empirical antibiotic treatment guidelines for CAP were followed for 126 (31.3%) of the CAP patients. At 4 h, antibiotics were administered intravenously to 244 (60.7%) of the CAP patients. At day 5, 218 (54.4%) received oral antibiotics. CONCLUSION: Adherence to CAP guidelines was poor. In a country with a restrictive antibiotic policy, infections are commonly treated with broad-spectrum antibiotics against recommendations.

The quality of life of older adults acutely admitted to the emergency department: A cross-sectional study.

AIM: To investigate perceptions of individual QoL among acutely admitted older adults and explore whether homecare and readmission were associated with QoL. DESIGN: A cross-sectional study at three Danish Emergency Departments. METHODS: Semi-structured interviews, using the Schedule for the Evaluation of Individual Quality of Life - Direct Weighting (SEIQol-DW) (range 0-100) with patients ≥65 years, were conducted from August 2018 to July 2019. The differences between patients receiving homecare (yes/no) and readmission (yes/no) were tested using linear regression analyses with bootstrap procedures. RESULTS: Overall, we included 406 patients, of whom 38% received homecare. The mean SEIQoL-DW-score was 76 (SD = 19). The most important areas of individual QoL were Family, Social activities, Health, Everyday life and Leisure activities. Receiving homecare was associated to a significantly lower QoL score: -8 (SE = 2) and a significantly lower score in the categories Family and Health. There was no association between readmission and QoL.

Expiratory Technique versus Tracheal Suction to Obtain Good-Quality Sputum from Patients with Suspected Lower Respiratory Tract Infection: A Randomized Controlled Trial.

Microbiological diagnostics of good-quality sputum samples are fundamental for infection control and targeted treatment of lower respiratory tract infections (LRTI). This study aims to compare the expiratory technique and tracheal suction on the quality of sputa from adults acutely hospitalized with suspected LRTI. We performed an open-label, randomized controlled trial. Patients were randomized to sputum sampling by tracheal suction (standard care) or the expiratory technique. The primary outcome was quality of sputum evaluated by microscopy and was analysed in the intention-to-treat population. The secondary outcomes were adverse events and patients experience. In total, 280 patients were assigned to tracheal suction (n = 141, 50.4%) or the expiratory technique (n = 139, 49.6%). Sputum samples were collected from 122 (86.5%) patients with tracheal suction and 67 (48.2%) patients with expiratory technique. Good-quality sputa were obtained more often with tracheal suction than with expiratory technique (odds ratio 1.83 [95% CI 1.05 to 3.19]; p = 0.035). There was no statistical difference in adverse events (IRR 1.21 [95% CI, 0.94 to 1.66]; p = 0.136), but patient experience was better in the expiratory technique group (p < 0.0001). In conclusion, tracheal suction should be considered a routine procedure in emergency departments for patients with suspected LRTI.

Limited value of sputum culture to guide antibiotic treatment in a Danish emergency department.

INTRODUCTION: Antibiotics resistance is increasing worldwide. The Region of Southern Denmark developed an antibiotic stewardship to reduce the use of broad-spectrum antibiotics in hospitals including microbiological diagnostics of sputum samples. The aim of this study was to evaluate the implementation of the stewardship in the emergency department (ED) concerning management of pulmonary infections. The objectives were: 1) to investigate whether the empirical therapy was prescribed correctly, 2) to identify the quality and results of pre-antibiotic sputum collection and 3) to investigate whether the antibiotic treatment was revised based on the microbiological results. METHODS: This was a quality assessment study. Patient files from patients discharged with either pneumonia or acute exacerbation of chronic pulmonary disease were reviewed, and written feedback was provided to the doctors, focusing on the regional guideline. RESULTS: Among the 257 medical records audited, the guideline was followed in 89% of the cases. Pre-antibiotic sputum samples were collected from 47% of the patients and 79% of these had sufficient quality for cultivation. None of the empirical antibiotic treatments were revised based on the microbiological results but some were revised based on other clinical parameters. CONCLUSIONS: Sputum samples had no clinical value for adjustment of the antibiotic treatment. Improvements of sputum sample collection and faster microbiological diagnostics are needed for sputum analysis to have any impact on the antibiotic treatment of patients with a pulmonary infection in the ED. FUNDING: none. TRIAL REGISTRATION: not relevant.

The effect of systematic functional assessment and immediate rehabilitation on physical performance in acutely admitted older adults with reduced functional performance: a randomised clinical trial.

Aims: We hypothesised that a systematic functional assessment in a short stay unit at an emergency department (ED) and/or immediate rehabilitation after discharge will result in sustained or improved physical performance in comparison to a regimen in which neither of these interventions is offered.Methods: A two-way factorial randomised clinical trial was completed in an ED and the primary sector. We enrolled 336 nonsurgical patients of 65 years or older, scoring eight or less in the 30-s chair stand test. The interventions were: 1) Usual assessment; 2) Usual rehabilitation; 3) A systematic functional assessment performed within 48 h of admission, in order to identify those with loss of functional mobility, or at risk thereof; and 4) Immediate rehabilitation initiated within five days after discharge. The primary outcome was the 30-s chair stand test three weeks after admission. Secondary outcome measures were Barthel, EQ-5D-3L, and length of stay (LOS).Results: An intention-to-treat analysis showed no significant difference in the 30-s chair stand test score nor when analysed by groups or by intervention. The changes were approximately 1% when compared to the reference. No significant differences were found in the secondary outcomes. A per-protocol analysis showed that 99% had received assessment as assigned; however, the extent of mobilisation during hospitalisation was not disclosed. Of the patients, 48% were received the post-discharge rehabilitation they were assigned to.Conclusions: Systematic functional assessment and immediate rehabilitation led to no significant differences in physical performance. The study was weakened by the incomplete implementation of mobilisation during hospitalisation and low adherence to protocol on immediate rehabilitation.Implications for rehabilitationA systematic functional assessment within the first 48 h of hospital admission is suitable for the identification of older adults in need of post-discharge rehabilitation when compared to usual assessment.To sustain physical performance in older adults during acute hospitalisation, further research focusing on mobilisation or physical activation is needed in older adults with a loss of functional mobility, or at risk thereof.Further research focusing on physical activation during transition is needed to ameliorate tiredness and inactivity in older adults after acute hospitalisation.

Validity and Responsiveness to Change of the 30-Second Chair-Stand Test in Older Adults Admitted to an Emergency Department.

BACKGROUND AND PURPOSE: Few physical performance measurement tools are validated for acutely admitted older adults, and for this reason we aimed to examine the validity and responsiveness to change of the 30-second Chair-Stand Test (30s-CST) used to assess physical performance in older adults admitted to a short-stay unit in an emergency department. METHODS: Construct validity of the 30s-CST, using 8 as a cutoff point for dependency in activities of daily living, was examined using 207 patients. Self-reported information on everyday activities was obtained by asking patients about need for help in bathing, dressing, cooking, cleaning, and shopping. Concurrent validity of the 30s-CST compared with the de Morton Mobility Index (DEMMI) on physical performance of acutely admitted older adults was examined with 156 patients. The analysis of concurrent validity included the entire DEMMI and 2 subsets of DEMMI: "DEMMI walking" and "DEMMI dynamic balance." The responsiveness to change in the 30s-CST compared with DEMMI was examined with 117 patients. All patients were classified as having either low physical performance (30s-CST ≤8) or high physical performance (30s-CST >8); these groups were used in the analysis of validity and responsiveness to change. RESULTS AND DISCUSSION: Regarding construct validity using 8 as a cutoff point, the study showed a significant difference between patients with low physical performance compared with patients with high physical performance. Moreover, a decrease in the 30s-CST was followed by an increase in the need for help with everyday activities. There was a significant association between the 30s-CST and DEMMI (r = 0.72); for every extra repetition in the 30s-CST, the DEMMI score increased by 4.9. There was a significant association between the 30s-CST and the 2 subsets "DEMMI walking" and "DEMMI dynamic balance"; yet, a pronounced floor effect was found in the subsets. The analysis demonstrated a very wide prediction interval, indicating that DEMMI has a better responsiveness to change than the 30s-CST, especially in older adults with low physical performance. However, the 30s-CST is easier and faster to use than DEMMI. CONCLUSION: This study found a significant difference in the patients' need for help with everyday activities when comparing low and high physical performance groups. The concurrent validity of the 30s-CST was acceptable in assessing physical performance in older adults at the time of admission; the 30s-CST is thus a tool that is easy to use in older adults with acute disease. In contrast, based on very wide prediction intervals, DEMMI demonstrated better responsiveness to change than the 30s-CST, especially in older adults with low physical performance.

Do prehospital providers and emergency nurses agree on triage assignment?: an efficacy study.

OBJECTIVES: The aim of this study was to investigate the agreement on triage level between prehospital providers and emergency department (ED) nurses in clinical practice when using the same triage system. The objectives were as follows: (a) What is the agreement of triage between prehospital providers and ED nurses, when using Danish Emergency Process Triage (DEPT) correctly? (b) Which part of the triage process yields the highest agreement regarding the final triage? METHODS: The study was a prospective and observational efficacy study. Patients transported to the ED by ambulances were included. They were triaged by prehospital providers while being transported by ambulance to the ED, and by ED nurses upon arrival. Triage was done using the DEPT - a five-level triage system based on vital signs and a presenting complaint algorithm. An agreement analysis was performed. RESULTS: DEPT was used correctly by both professions in 292 patients. In 182 (62%) patients the prehospital providers and the ED nurses agreed on the same triage level. This equals to κ=0.47 [95% confidence interval (CI): 0.41-0.56]. When considering the triage based on vital signs the agreement was 72% (κ=0.46; 95% CI: 0.41-0.47), and based on presenting complaint the agreement was 46% (κ=0.41; 95% CI: 0.37-0.44). CONCLUSION: There was a moderate interrater agreement on triage assignment between ED nurses and prehospital providers. They agreed on final triage more often if they agreed on triage based on vital signs rather than presenting complaints.

Time delay to surgery for appendicitis: no difference between surgical assessment unit and emergency department.

BACKGROUND: In Denmark, emergency departments (EDs) are replacing acute surgical and medical units. The aim of this study was to compare the trajectory of patients undergoing surgery on the suspicion of appendicitis in a surgical assessment unit (SAU) and EDs with an observation unit, respectively. The primary outcome measure was the time from hospital arrival-to-decision for surgery. MATERIALS AND METHODS: A comparative retrospective study with a cross-sectional design and a before-and-after design was carried out during January 2011 to December 2012 at a SAU and an ED at a university hospital (U-SAU and U-ED) and at an ED at a regional hospital (R-ED). Data included time of arrival, decision for surgery, surgery and discharge, and number of blood tests. RESULTS: In total, 250 patients were included. Time to decision for surgery was 4.50, 4.95, and 4.63 h (P=0.58) in the U-SAU, R-ED, and U-ED, respectively. Time from decision for surgery to start of surgery was 4.60, 3.29, and 4.12 h in the U-SAU, R-ED, and U-ED, respectively. The difference was significant between the U-SAU and R-ED (P=0.05) and between R-ED and U-ED (P=0.03). Time from surgery to discharge from the hospital was 17.88, 19.28, and 15.13 h in the U-SAU, R-ED, and U-ED, respectively. The difference was significant between the EDs (P=0.02). Significantly more blood tests were performed in the EDs than in the U-SAU. CONCLUSION: The introduction of EDs with observation units did not influence time to decision for surgery, but more blood tests were performed.

Pallor as a sign of anaemia in small Tanzanian children at different health care levels.

BACKGROUND: Anaemia is a major complication of Plasmodium falciparum malaria among small children in sub-Saharan Africa. We studied the performance of the Integrated Management of Childhood Illness (IMCI) recommended assessment of no/some/severe pallor as predictor of anaemia in health surveys at community level and in clinical practice in an out patient department (OPD) and in a hospital ward in rural Tanzania. METHODS: The study was undertaken among 6-36 months old children. Pallor was evaluated as a combined assessment of conjunctiva, tongue and palms and categorised as no, some or severe pallor. Packed cell volume (PCV) was measured and related to pallor. FINDINGS: A total of 740 examinations were performed at village, OPD and in the hospital ward. The prevalences of severe pallor were 0%, 1.5% and 7% respectively. The prevalences of any pallor were 14%, 41% and 86%. The prevalences of severe anaemia (PCV<21%) were 1%, 5% and 81% and of any anaemia (PCV<33%) 68%, 73% and 98%. Severe pallor could not detect severe anaemia. The sensitivities were only 0%, 0% and 8%. The sensitivities of any pallor to detect severe anaemia were however 86% and 98% for children at the health care facility level, but still of relatively poor predictive values since the specificities were only 61% and 68%. INTERPRETATION: Division of pallor into some or severe degrees was of no use at any health care level. The identification of any pallor was of no use at village level, but it may possibly be of some value as a screening test for severe anaemia at health care facilities, if additional assessment is included in view of the low specificity and positive predictive value of the finding.

Algorithm for the diagnosis of anaemia without laboratory facilities among small children in a malaria endemic area of rural Tanzania.

BACKGROUND: Anaemia among small children in tropical Africa is common and often caused by infection with Plasmodium falciparum. The diagnosis of anaemia is difficult without a laboratory estimation of haemoglobin. The aim of this study was to examine if clinical findings related to malaria and anaemia would help to detect moderate and/or severe anaemia in children in rural Tanzania. METHODS: Children between 6 and 36 months were examined by health workers in an Out Patient Department (OPD) to detect severe anaemia (packed cell volume, PCV< or =20%) and in a cross sectional survey at village level to identify moderate anaemia (PCV 21-25%). History of recent fever and treatments was recorded and a clinical examination was performed. FINDINGS: In the survey, comparison of 65 moderately anaemic children with 373 mild/non anaemic children revealed no differences in history of fever or in the clinical examination. In the OPD comparison of 100 severely anaemic children with 116 non-severely anaemic control children revealed that pallor, respiratory rate, number of fever days last week, deteriorated general condition, heart rate, age, splenomegaly, low body weight and elevated body temperature were all indicators of severe 'anaemia, only pallor, respiratory rate, fever days and palpable spleen however, remained associated with severe anaemia in multiple regression analysis. The combination of any pallor and either respiratory rate >55/min or fever >3 days, could predict severe anaemia with a sensitivity of 96% and a specificity of 71%. This was better than the currently recommended signs of severe pallor or an approximation of the Integrated Management of Childhood Illness (IMCI) criteria's for referral of children. INTERPRETATION: At primary health care level detection of severe anaemia can be improved by information about fever duration and determination of respiratory rate in children with pallor.

A combination of clinical parameters and blood-gas analysis identifies patients at risk of transfer to intensive care upon arrival to the Emergency Department.

OBJECTIVES: Identifying patients at risk of transfer to the ICU upon arrival to the Emergency Department (ED) might direct early therapy and optimize transfers. However, among the many ED patients, it is difficult to pinpoint the few who insidiously deteriorate to an ICU-requiring level. The aim of this study was to identify predictors in background information, vital values and blood-gas analysis for transfer to ICU 3-36 h after arrival among nontrauma ED patients. METHODS: A case-control study of 10 007 acute adult patients admitted to ED within 1 year was carried out. The case group consisted of all ICU transfers 3-36 h after arrival who underwent blood-gas analysis and a similar control group not transferred to the ICU. Blood pressure, respiratory frequency, pulse rate, peripheral oxygen saturation and temperature, triage, height, weight, Glasgow Coma Score, drugs, alcohol, tobacco, age, sex, Charlson score and blood-gas results were analysed. RESULTS: A total of 49 medical and 33 surgical patients were transferred to the ICU. For medical cases, 2.3 and surgical cases 3.7 controls were included. For medical patients, low systolic blood pressure [odds ratio (OR) 14.4], elevated heart rate (OR 3.9), severe acidosis (OR 5.1) and hypercapnia (OR 8.4) and for surgical patients age 60-79 years (OR 6.3), low diastolic blood pressure (OR 2.7) and severe acidosis (OR 15.3) were associated significantly with later transfer to the ICU. CONCLUSION: The predictors identified could be used as part of ED triage to identify high-risk patients for ICU. These findings should be examined in a well-designed prospective cohort study.

[Osteoporosis prevention in patients with low energy hip fractures hospitalized in the orthopedic department]. / Osteoporoseprofylakse hos patienter indlagt med hoftenaere lavenergifrakturer på ortopaedkirurgisk afdeling.

INTRODUCTION: The aim of this study was to investigate the following in patients treated for low energy hip fractures: 1) whether they were using osteoporosis preventative therapy before admission to hospital; 2) whether therapy was initiated before discharge from hospital; 3) the therapy used; and 4) whether they were referred for follow-up treatment for osteoporosis after discharge. MATERIAL AND METHODS: We carried out a retrospective study of medical journals on patients with a hip fracture, brought into the Department of Orthopaedic Surgery in 1997-1998. RESULTS: One hundred and forty-six patients, 80% women and 20% men with an average age of 80.7 years, were hospitalised during this period. Twenty patients had specific risk factors for developing osteoporosis, five patients of whom were taking osteoporosis preventative therapy. On admission, eight patients were in treatment. One patient started treatment during the hospital stay. Forty percent of the patients on discharge were referred for treatment by their GP or at the Department of Internal Medicine. DISCUSSION: Of the patients brought into the Department of Orthopaedic Surgery with low energy hip fractures, 6.2% were given the relevant medical treatment for osteoporosis on discharge from hospital, and only one of these patients started osteoporosis preventative therapy during the stay. As the study shows that 14% of the patients had specific risk factors for developing osteoporosis, only 25% of whom started treatment before admission to hospital, we find a need for osteoporosis preventative therapy in this group of patients.
