Lumbar punctures: use and diagnostic efficiency in emergency medical departments

International Journal of Emergency Medicine volume 2, pages 227–235 (2009)Cite this article

Abstract

Background

Lumbar punctures (LP) are regularly and effortlessly used in the emergency medical departments (EMD). LP use and efficiency have not been fully explored in the published literature.

Aims

The goal of this study was to assess in a French EMD, the frequency of use and the diagnostic efficiency of LP, the final diagnoses, and related medical practices.

Methods

We retrospectively studied all patients who underwent an LP after admission to our adult EMD in 2004 and 2005. Patients’ medical files were reviewed to collect clinical and paraclinical features. We defined efficient LP as abnormal LP, which confirmed a suspected diagnosis in an emergency setting.

Results

A total of 247 patients, representing 0.5% of all admissions, underwent an LP. LP were efficient in fewer than 15% of cases and confirmed aseptic meningitis (8.5%), bacterial meningitis (2.4%), Guillain-Barré syndromes (1.6%), subarachnoid hemorrhages (SAH, 0.4%), and carcinomatous meningitis (0.4%). The principal differential diagnoses were infections outside the central nervous system (CNS, 30%), noninfectious neurological disorders (28.7%), and benign headaches (14.2%). The main assumed LP indications were to search for CNS infection (62%) and for SAH (25%). LP efficiency decreased dramatically according to patients’ age. Brain imaging was performed in 90% of patients prior to LP. Excessive use of polymerase chain reaction to detect herpes simplex in cerebrospinal fluid was observed. The only LP complications found were postdural puncture headaches (6.1% of cases). The rate of traumatic LP was 17%.

Conclusions

Our results are in accordance with the few published surveys on this topic. LP efficiency is modest but must be considered in light of the seriousness of suspected diagnoses. However, the search for differential diagnoses should not be neglected.

Introduction

Lumbar punctures (LP) are regularly and effortlessly used in emergency medical departments (EMD) [1]. They are essentially employed [2] in order to confirm a central nervous system (CNS) infection [3] or a subarachnoid hemorrhage (SAH) [4], whilst brain imaging is not contributive. LP can also be useful when an acute inflammatory polyradiculoneuropathy (Guillain-Barré syndrome, GBS) is suspected [5]. These disorders can compromise patients’ vital and functional prognoses [3, 6, 7]. Therefore, efficient diagnosis strategies (using LP) are required for EMD patients with suspected meningitis, SAH or GBS.

However, LP use and efficiency have not been fully explored in the published literature. Considering published literature data, only few surveys studied the use and the diagnostic efficiency of LP in the EMD [1, 5, 8, 9]. Furthermore, none of the published studies used French populations.

LP efficiency (yield) is assumed to be modest especially among elderly patients [10] when an infection of the CNS is suspected. Some findings [1] would appear to suggest that the examination of cerebrospinal fluids (CSF) in the EMD may not always be necessary and that some CSF tests may be excessive. Considering SAH and GBS, while these diseases are infrequently supported by LP results in the EMD [5, 9], missed diagnoses of SAH in the EMD have been reported [11]. Hence, there is a need for further investigations to explore the use and the efficiency of LP performed in the EMD. The main associated investigations, such as computed tomography (CT) of the brain prior to LP [3, 12–17] and CSF tests [18–20], are also important to assess.

In view of the lack of published literature on the use of LP in the EMD, we conducted an observational retrospective study to investigate the frequency of LP use in an emergency setting, the diagnostic efficiency of LP, and the usefulness of CSF tests. We also assessed medical practices associated with the use of LP, such as performing a CT scan prior to an LP; LP complications were also investigated.

Material and methods

Population studied

We performed a retrospective study, selecting all patients who underwent an LP in the adults’ EMD of a general hospital in Arras, in the north of France, between January 2004 and December 2005. The patients studied were those who underwent an LP during the phase of care in the EMD. The CSF results relating to the first successful LP procedure for each admission were collected as well as patients’ clinical, biological, and brain imaging findings.

Methods

We assessed the frequency of LP use in our EMD compared to the number of admissions (in 2004 and 2005). We reviewed the medical files of the selected patients. Final diagnoses, patients’ clinical features, CSF test findings, and the other paraclinical explorations (CT) were assessed and entered in a database. The retrospective design of our survey led us to assess LP indications and final diagnoses using independent examinations of patients’ medical files performed by two emergency physicians. Dates of admission, brain CT, and LP were also available.

We conducted a descriptive analysis to explore patients’ features and to assess associations with final diagnoses. Efficient LP were defined as abnormal LP, which confirmed suspected specific diagnoses in an emergency setting (infections of the CNS, SAH, and GBS).

Proportions were computed with confidence intervals of 95% (95% CI) and chi-square tests were used [21]. Standard CSF test findings were compared according to the type of meningitis diagnosed: aseptic (lymphocytic) or bacterial. In view of the expected modest efficiency of LP in the EMD, nonparametric tests were used where necessary. S-Plus statistical software was used for the data analysis.

Results

Frequency of LP use

A total of 247 patients underwent an LP after admission to the EMD between January 2004 and December 2005. There were 46,483 admissions during this period. Thus, 0.53% (0.47–0.60) of admitted patients underwent an LP. When analyzed monthly, the proportion of patients who underwent an LP varied widely, from a minimum of 0.24% to a maximum of 0.94%. Nonetheless, no significant difference was found that could indicate a possible seasonal variation in the use of LP (p = 0.28).

Patients’ clinical features

In our population, the median age was 52 years (36–72), and the sex ratio (male to female) was 1.12.

Full size table

Neurological diseases, alcoholism, diabetes, and chronic headaches were the most frequent features in medical records (Table 1). Neurological diseases and diabetes were the most frequent features in elderly patients (aged above 65 years old). Alcoholism was overrepresented in the middle-aged patients (aged between 35 and 65 years old). Chronic headaches were the most frequent feature in the youngest patients (aged less than 35 years old).

Among patients’ clinical features observed at admission or at the clinical examination, nonfocal neurological symptoms (delirium or acute confusion), fever, and symptoms conducive to an infection outside the CNS were the most frequent findings. Symptoms comprising the meningitis syndrome, such as headaches, neck stiffness or pain, vomiting, photophobia, and phonophobia, were also observed. These symptoms were overrepresented among young patients; headaches were reported by three quarters of young patients. Elderly patients more often presented with fever, clinical signs suggesting infections outside the CNS, and nonfocal neurological signs (mainly confusion).

Focal neurological signs, seizures, and abnormal consciousness were reported each for a little more than 10% of our population and were infrequently observed among the young patients. Middle-aged patients more frequently presented with seizures.

LP indications

The assumed indications for LP were principally the search for CNS infections (61.9% of the cases) followed by the search for SAH (25.5%) and GBS (3.2%). The search for CNS infections were most frequent among the elderly patients, representing almost 80% of LP indications (Table 1). LP motivated by the search for SAH represented 32% of cases among patients of less than 65 years old versus 14% among older patients. LP indications were indeterminate or uncertain for a little less than 10% of our population.

Final diagnoses

Of the 247 patients who underwent an LP, CSF analysis confirmed 21 cases of aseptic (lymphocytic) meningitis (8.5%), 6 cases of bacterial meningitis (2.4%), and 1 case of SAH (0.4%) (Table 1, Figs. 1 and 2). LP contributed to the diagnosis of GBS in four cases (1.6%) and of carcinomatous meningitis in one case (0.4%). Lymphocytic meningitis was more frequently observed among younger patients.

When the lumbar puncture results were not contributive (normal or negative), the final diagnoses were essentially infections outside the CNS (30%), neurological diseases (28.7%), and benign headaches (14.2%).

The main sites reported suggestive of infections outside the CNS were pulmonary, urinary, and in the upper respiratory tracts. Pulmonary and urinary sites were more frequently observed among elderly patients, whilst upper respiratory tract sites were more often reported among young and middle-aged patients. Pulmonary (34%) and urinary (24%) infections represented the two main sites of infections outside the CNS. As expected, these infections were overrepresented among elderly patients, representing, respectively, 18 and 14% of final diagnoses.

Compared to the other patients, the youngest patients more frequently presented with benign viral infections (7.1% of all diagnoses) and benign headaches (30.4%). They also presented with fewer noninfectious neurological disorders: 16% of final diagnoses versus 38% among middle-aged patients and 30% among elderly patients (p < 0.05). Differential noninfectious neurological disorders were more often observed among older patients and were mostly seizures and strokes: they represented, among noninfectious neurological disorders, 44 and 24% of diagnoses, respectively. Seizures, representing a final diagnosis, were overrepresented among middle-aged patients (19% of all diagnoses), whilst strokes were overrepresented among middle-aged and elderly patients (8% of all diagnoses).

LP efficiency and CSF tests

Contributive LP represented 13.4% (95% CI: 9.1–17.6) of the cases and varied significantly according to patients’ age: the proportion of efficient LP decreased from 25% among young patients to 14.2% among middle-aged patients and to less than 5% among elderly patients (Table 1 and Fig. 1).

A large majority of these positive and contributive LP (63.6%), confirming a suspected specific diagnosis in an EMD setting corresponded to a diagnosis of aseptic (lymphocytic) meningitis.

One of the cases of aseptic meningitis was concomitant with a clinical and serum diagnosis of an Epstein-Barr virus infection that was not confirmed by the CSF tests. The search for herpes simplex in CSF, using a herpes simplex polymerase chain reaction (PCR), was performed in 126 patients but was positive in only one case. Among the cases of bacterial meningitis (n = 6), three were caused by Streptococcus pneumoniae, one by Streptococcus agalactiae, and one by Staphylococcus aureus. Unfortunately, in one case, the bacteria could not be identified, whilst CSF characteristics were undoubtedly in accordance with a diagnosis of bacterial meningitis.

A comparison of standard CSF tests between aseptic (lymphocytic) and bacterial meningitis showed several consistent differences (Table 2).

Full size table

Soluble antigens were detected in the CSF in all cases of pneumococcal meningitis, and the germ could also be identified immediately. This CSF test was ordered for only 15 patients.

Taking into account the cutoff points proposed by Shah et al. [22] for the red blood cell count in CSF, there were 10.1% (6.1–14.1) of traumatic LP when the cutoff value was 1,000/mm3 and 17% [12–22] when the cutoff value was 400/mm3.

Medical practices and complications related to LP use

Almost all patients underwent a CT prior to the LP [89.9% (86.1–94.6)], independently of LP indications (Table 1). When LP were performed within the first 24 h after admission, the median delay between admission and cranial CT was 2 h; the median delay for patients admitted between midnight and 6 a.m. was 7 h. The median delay between admission and LP results was 6 h, whereas delays of up to 10 h were recorded for some of the patients admitted between midnight and 6 a.m. A positive correlation was found between the delay before cranial CT and the delay before obtaining LP results: the correlation coefficient was 0.6 (p < 0.0001).

In terms of LP complications, only postdural headaches were reported among patients admitted secondarily to the neurological and medical units. Postdural puncture headaches (PDPH) were reported in 6.1% (3.1–9.1) of patients who underwent an LP.

More than four fifths of patients were admitted to hospitalization units, whilst 14% were discharged from the EMD. When compared to patients admitted to hospitalization units, patients discharged from our EMD were much younger: 39% of discharged patients were less than 35 years old versus 20% among admitted patients. Discharged patients also presented more frequently with less severe final diagnoses such as benign headaches (36 versus 11%) and mild psychiatric disorders (15 versus 3%).

Discussion

Our study provides a relevant appraisal of the use and the diagnostic efficiency of LP in an EMD setting. LP was performed occasionally in 0.5% of the patients admitted to our adult EMD. The assessment of final diagnoses indicates a modest efficiency (yield) of LP, namely in fewer than 15% of cases. Among efficient LP, aseptic (lymphocytic) meningitis was the most frequent diagnosis, whereas the search for an infection of the CNS was the most frequent indication for LP. Thus, patients could benefit from optimal treatments and strategies of care, based upon the results of CSF analyses. In cases of ineffective LP, the principal differential diagnoses were infections outside the CNS, noninfectious neurological disorders (seizures and strokes), and benign headaches.

Though LP efficiency decreased dramatically according to age, differential diagnoses (diagnoses found in cases of inefficient LP) also varied substantially according to patients’ age. Differential diagnoses among elderly patients were principally represented by infections outside the CNS, mainly in the urinary and respiratory tracts, and by seizures and strokes. Middle-aged patients presented more frequently with seizures and benign headaches as differential diagnoses. Benign headaches represented the most frequent final diagnosis among young patients. Observed infectious diseases outside the CNS were located mostly in the upper respiratory tracts among middle-aged and young patients.

Considering the seriousness of meningitis, SAH, and acute GBS disorders, which may compromise patients’ functional and vital prognoses, LP represent a consistent tool to rule out SAH [16] or meningitis [3] and to support a diagnosis of suspected acute GBS [23] in an EMD setting. Therefore, despite the modest efficiency of CSF examinations revealed by our results, negative or normal CSF findings can be informative and useful. However, before performing an LP, the main differential diagnoses should be considered, so as to improve the justification and indication for the LP procedure. This is particularly important for the elderly patients whose LP yield is very weak (5% of cases). Nevertheless, the modest specific diagnostic efficiency of LP observed in our study (13.4%) remains difficult to interpret. It can represent a balance between consistent resource utilization versus misdiagnosis.

Our results were in line with the findings of the few published studies exploring LP use and efficiency in EMD settings. The frequency of LP use found in our study was comparable to that found by Mòdol et al. (0.4%) [8]. The distribution of efficient LP diagnoses in our study was also in line with the results of Mòdol et al.’s study [8], which found that the principal indication for LP in an adult EMD was a suspected CNS infection (76%). Only 30% of the CSF examinations confirmed the diagnosis of acute meningitis among LP performed to search for a CNS infection. A modest efficiency of LP has also been reported by Powers [1] and Warshaw et al. [10]. Warshaw et al.’s study found a very weak efficiency of CSF analysis among elderly patients presenting with fever and delirium; the principal final diagnoses were pulmonary, urinary, and viral infections, dehydration, and metabolic causes. After an appraisal of 104 CSF examinations, Powers [1] also found a modest efficiency of LP performed in an EMD, almost all CSF tests giving normal or negative results. Moreover, the author of that study recommended limiting the laboratory testing of CSF.

A low incidence of GBS in an emergency setting was recently reported by McGillicuddy et al. [5]. In addition, an acute GBS diagnosis is usually confirmed by electrodiagnostic testing [23]. As is the case for GBS, SAH [9] diagnoses using LP results are infrequent in the EMD. Occurrences of GBS and SAH observed in our study are supported by Perry et al.’s [9] and McGillicuddy et al.’s [5] findings. Nonetheless, difficulties in diagnosing these pathological conditions have been reported [4, 5, 11, 24].

The commonest complication of LP is PDPH [25], whereas other, more serious complications have exceptionally been observed, such as cerebral herniation [26], spinal hematoma [27], iatrogenic spinal tumor [28], and induced meningitis [29]. The incidence of PDPH after a diagnostic LP procedure can vary from 6 to 40% [30, 31]. In our survey, a rate of PDPH of 6.1% was found. No other LP complications have been observed. However, our rate of PDPH may be underestimated. Information not reported in patients’ files and early discharge from the EMD to home (14% of patients) represent potential mechanisms of misclassification.

Significant differences between aseptic and bacterial meningitis were found in our study, when standard CSF tests were considered. While standard CSF tests are known to provide valuable support in differentiating bacterial from aseptic (lymphocytic) meningitis [32], some authors have suggested that these standard tests are only moderately useful in the event of a negative Gram-stained smear [19, 33, 34]. Other specific CSF and blood serum tests have been proposed to better appreciate the likelihood of bacterial meningitis [18, 35].

The usefulness of the occurrence of soluble antigens in CSF was limited in our survey; however, this CSF test was infrequently employed (6% of CSF) in accordance with published data [36–39]. Very low efficiency was achieved with the use of herpes simplex PCR in our study. This result suggests an excessive use of this CSF test (51% of CSF, one positive result). Excessive herpes simplex PCR testing is linked to the frequent use of this test in patients whose CSF did have a normal count of leukocytes (in 81 of 126 cases). Ordering this test may have been systematic to rule out a very weak likelihood of herpes simplex meningoencephalitis [20].

Taking into account the blood cell count cutoff points proposed by Shah et al. [22], the rates of traumatic LP observed in our study were similar to previously published data.

Among elderly patients, fewer than 5% of LP were efficient, whilst almost four fifths of LP were employed to search for a CNS infection. The majority of infections detected among elderly patients were principally located in the respiratory or urinary tracts. Moreover, clinical signs notably suggesting infections located outside the CNS were found in fewer than half (41%) of the elderly patients.

Greater yield of LP was found among young (25% of cases) and middle-aged patients (a little less than 15% of cases). Among these subpopulations, efficient LP documented primarily infections of the CNS (mainly aseptic meningitis). Younger patients more frequently presented with obvious clinical signs of meningism. LP indications among these patients may have corresponded to a higher clinical suspicion of meningitis. In contrast to the younger patients, elderly patients may have undergone LP to rule out the possibility of a CNS infection. Clinical signs suggesting a diagnosis of meningitis or encephalitis can be misleading in elderly patients [40]. Clinical suspicion of CNS infection is assumed to have differed widely between these subpopulations and can explain the differences observed in LP efficiency. In addition, when LP were performed to rule out an assumed weak likelihood of meningitis, markedly among elderly patients, brain CT and LP may have been delayed.

The usefulness of performing a CT prior to an LP depends on the patient’s clinical condition and the suspected diagnosis. Fitch et al. [3] reported on patients’ conditions that require a CT to be performed before an LP when a CNS infection is suspected, whereas Hasbun et al. [15] showed that patients’ clinical features can reliably be used to assess the usefulness of CT. Furthermore, a very low prevalence of abnormal CT, contraindicating LP, was observed in a study of 113 patients admitted to an EMD who were considered to require an LP [41]. Nonetheless, many clinicians routinely order a CT prior to LP [14, 42]. Although this strategy may be reassuring, it may sometimes lead to a substantial delay in diagnosis and thus in optimal treatment, especially when the availability of CT is limited [9, 43]. In addition, this practice may lead to clinical contraindications being overlooked [14].

With regard to medical practices related to the use of LP, in our study, a brain CT prior to LP seems to be routinely employed: clinical signs (focal neurological signs, seizures, or abnormal consciousness) requiring a brain CT prior to the performance of an LP were found among less than a third of our population. Unexpectedly, approximately 90% of patients who underwent an LP to search for an infection of the CNS had CT prior to LP. Significant delays have been observed between admission, the brain CT, and LP results, especially when admissions occurred between midnight and 6 a.m. Flais et al. [43] reported a huge decrease in CT use between midnight and 6 a.m. for emergency demands. When LP are performed in order to search for an infection of the CNS, ordering a CT prior to an LP can lead to an important delay of the LP procedure. Thus, administration of antibiotics may also be delayed, compromising the prognosis of patients with bacterial meningitis [44].

In the event of a negative brain CT, it is recommended to wait for at least 6 h between the onset of symptoms and the performance of an LP when SAH is suspected [6]. This practice is in accordance with observed CT and LP procedure delays in our survey. SAH diagnoses are more frequently confirmed using brain imaging [9], which is usually performed as the first-line diagnostic tool [45]. However, in spite of brain CT enhancement using fifth generation CT scanners, which improves the diagnosis of SAH [46], the sensitivity of noncontrast CT imaging may, in some cases, remain insufficient [13]. Hence, the use of LP remains necessary to rule out SAH [16]. However, LP are not reported to be systematically used in the event of negative brain CT [4, 9]. Furthermore, whether an LP is indicated in the event of a negative brain CT when a SAH is suspected has been recently disputed [6, 47, 48]. Vermeulen et al. [11] assessed the rate of missed SAH among emergency department patients; a rate of 5.4% (4.3–6.6) was found among a population of 1,507 patients.

In our study, assumed SAH indications for LP represented only 25.5% of the cases and only one case of SAH was found using an LP. SAH indications were more frequent among middle-aged and young patients. Headaches, as a record or a symptom observed during the clinical examination, were overrepresented among these patients. Although missed SAH diagnosis could not be studied in our survey, very infrequent diagnosis of SAH from LP results can be linked to the effectiveness of brain imaging diagnosis (when CT are performed prior to LP) and limited indications for LP in relation to emergency physicians’ strategy of care.

Several limitations, linked to the retrospective nature of our study, must be considered when assessing our results. LP subsequently performed in hospitalization units after an initial admission in the EMD were not taken into account, leading to a potential selection bias. However, LP performance in the hospitalization units could be influenced by changes in clinical or biological features. In this study, our aim was to assess emergency medical practices in relation to patients’ initial characteristics observed in the EMD. Classification and information biases can result from the retrospective reviewing of patients’ medical files, leading to a more difficult assessment of patients’ features, indications for LP, and final diagnoses. Thus, two emergency physicians reviewed patients’ medical files independently and the concordance of our results with the literature data suggests that these biases are limited.

A better assessment of the efficiency of LP would undoubtedly be achieved in a prospective setting with a larger study population. This would allow a more precise and reliable assessment of LP indications, patients’ features, delivery of anti-infective treatments (in cases of suspected meningitis), and outcomes during a follow-up. Missed meningitis and SAH diagnoses, in the EMD, would also be appreciated. The assessment of medical practices, illustrated by the use of brain CT prior to LP (in cases of a possible infection of the CNS) and herpes simplex PCR tests, suggests that the current published guidelines and data were not fully taken into account. A prospective survey would permit evaluation of potential improvements in medical practices after a review of current guidelines.
