Abstract

Despite publication of several management guidelines for COPD, relatively little is known about standards of care in clinical practice.

Data were collected on the management of 1400 cases of acute admission with Chronic Obstructive Pulmonary Disease in 38 UK hospitals to compare clinical practice against the recommended British Thoracic Society standards. Variation in the process of care between the different centres was analysed and a comparison of the management by respiratory specialists and nonrespiratory specialists made.

There were large variations between centres for many of the variables studied. A forced expiratory volume in one second measurement was found in only 53% of cases. Of the investigations recommended in the acute management arterial blood gases were performed in 79% (interhospital range 40–100%) of admissions and oxygen was formally prescribed in only 64% (range 9–94%). Of those cases with acidosis and hypercapnia 35% had no further blood gas analysis and only 13% received ventilatory support. Long-term management was also deficient with 246 cases known to be severely hypoxic on admission yet two-thirds had no confirmation that oxygen levels had returned to levels above the requirements for long-term oxygen therapy. Only 30% of current smokers had cessation advice documented.

To conclude, the median standards of care observed fell below those recommended by the guidelines. The lowest levels of performance were for patients not under the respiratory specialists, but specialists also have room for improvement. The substantial variation in the process of care between hospitals is strong evidence that it is possible for other centres with poorer performance to improve their levels of care.

Chronic obstructive pulmonary disease (COPD) has a high prevalence and is one of the most common causes of emergency medical admission with a respiratory disorder in the UK 1, 2. Several national and international Thoracic Bodies have produced management guidelines 3–7 but relatively little is known about the standards of care of COPD as practised. Published studies encompass few hospitals, small patient numbers, and are not measured against nationally agreed standards. For example data from a sample of l00 cases from the West of Scotland suggested that care by respiratory specialists was better than that given by generalists 8. A study from a single New Zealand hospital concluded that process of care was “adequate” measured against a local consensus view 9. Following the launch of the British guidelines 7 the British Thoracic Society (BTS) performed an audit of the clinical practise of hospital care of patients admitted with acute exacerbations of COPD. The aims of the audit were to establish data on the current management of acute COPD in UK hospitals judged against the British guidelines and to identify differences in management between respiratory and nonrespiratory specialists.

Methods

Hospitals within the UK with acute Respiratory Medicine Departments were approached to participate in the study. All were asked to complete retrospective audit sheets from information held in case-note records on 40 consecutive admissions from September 1, 1997 with a clinical diagnosis of acute exacerbation of COPD as the admission criterion. The audit proforma developed by the BTS audit group, comprised 38 questions some with two or more stems covering the following areas of care: 1) background information and history prior to admission; 2) assessment and measurements on admission; 3) initial management; 4) continuing management and discharge, which included identifying the consultant responsible at the point of discharge as a respiratory specialist or other specialist; 5) follow-up in the three months after admission. The following standards were taken from the BTS guidelines for the five sections.

Background information

Forced expiratory volume in one second (FEV1) should be recorded to establish the diagnosis. When recorded as percent of predicted, an FEV1>80% effectively excludes the diagnosis. Any record in the previous 5 years or in 3 months after admission was accepted.

Assessment and measurements on admission

Three symptoms should be recorded: increased dyspnoea, increased sputum volume, increased sputum purulence. The signs to be elicited include presence of purulent sputum, presence of peripheral oedema, temperature, tachypnoea. Urgent investigations should include arterial blood gas tensions noting the inspired inspiratory oxygen fraction (FI,O2), an initial peak flow and a chest radiograph.

Initial management

Guidelines recommend that oxygen therapy should be controlled (and the FI,O2 be ≤28%) until blood gas tensions are known.

Blood gas tensions should be repeated if initially patient is acidotic or hypercapnic, nebulized bronchodilators should be given, antibiotics and steroids administered where appropriate, ventilatory support (noninvasive positive pressure ventilation (NIPPV) or via endotracheal tube) should be considered in those with a pH<7.26 and a rising arterial carbon dioxide tension (Pa,CO2).

Continuing management and discharge

The following are recommended: a peak flow chart should be started as soon as possible, FEV1 should be recorded before hospital discharge, arterial blood gases should be checked on air for those presenting with an initial low Pa,O2. Discharge planning should include review of inhaler technique and smoking cessation advice to be given and documented for those still smoking prior to admission.

Follow-up

During later clinical stability formal reversibility testing should be undertaken, pulmonary rehabilitation considered whilst influenza vaccination is recommended for the elderly and those with severe COPD.

The audit proforma was accompanied by a detailed explanation of the reasoning for each question, possible answers, and guidance on where such information might be found within the case notes. Each centre nominated a consultant lead to be responsible for data quality and collection. A small payment was made on receipt of the completed audit forms. In order to check quality control five sets of case notes from each participating site were audited by a second observer usually a doctor in training from the same department.

Statistics

Results are expressed for all cases in the audit, usually as percentages for all hospitals combined. Percentages were also computed for individual hospitals: the variation in hospital performance is summarized by the inter-quartile range (IQR) and range of hospital percentages. Where data are incomplete this is clarified by the stating of the numerator and relevant denominator alongside the percentage calculated.

A comparative analysis was performed on the data collected for continuing management and discharge between those cared for by specialist physicians and nonspecialist physicians. P‐values from Chi-squared tests of significance and 95% confidence intervals (CI) for the difference between group percentages were calculated. This section of the analysis was limited to those aspects of patient care that might reasonably be expected to form the responsibility of the consultant in charge at the time of discharge. This was because the audit form asked specifically for this information and not the specialty under which the patient was admitted.

Results

Forty-three centres submitted audit data for analysis. Fourteen were University teaching hospitals and the remainder district hospitals. A total of 1,400 cases were available for analysis, median contribution 40 per centre, IQR 26–40. Dates of admission were known for all but one and 90% of admissions occurred during the months of September, October, and November 1997. Twenty-seven patients were included twice in the audit as re-admissions during the counting of consecutive cases. Thus, there were a total of 1,373 different patients included in all. For the analysis of the standards of care all 1,400 admissions are included and may be referred to as “cases”.

Table 1⇓ provides demographics and indices of disease severity at admission. Sixty-six per cent, (919/1400) of patients had a previous admission for COPD. Only 29% (400/1400) were first time admissions, with this information unknown in 6% of cases. Of the re-admissions 6% (51/919) had been admitted within the preceding two weeks and 36% (333/919) between 2 weeks and 4 months prior to the index admission. Measurement of FEV1 within the previous 5 yrs or subsequent 3 months was found in only 53% (739) cases ((interhospital range 0–93%), FEV1 as per cent pred was available in only 37% (514)) and 5% (26) of all cases had a predicted value >80%. Median length of staywas 8 days (IQR 4–12). Death from COPD within months of admission was recorded in 184/1342 cases (14%).

Demographics and disease severity at admission

Assessment and measurement on admission

The audit questionnaire examined, the documentation of three symptoms; “increased breathlessness”; “increased sputum volume”; and “change in colour of sputum”. Relevant entries were found in almost all cases for “increased breathlessness” but in only about two-thirds of cases for the other two symptoms. Respiratory rate was recorded in 70% (982) of all cases, presence or absence of bilateral leg oedema in 66% (923), and temperature in 86% (1209) (table 2⇓).

Table 2

Assessments and measurements on admission

A comment on the chest radiograph was recorded within the first 24 h in 65% (916) of cases and described infiltrates in a quarter of these. Arterial oxygen saturation (Sa,O2) was recorded by pulse oximetry in 76% (1061/1400) of admissions and was whilst breathing room air in 26% (275). Arterial blood gases, were performed in 79% (1109) of admissions. The inspired oxygen concentration was noted in 71% (786/1109) of these with 27% (296) breathing room air. In 19 cases an Sa,O2 of ≤92% was recorded but no arterial blood gas was performed.

Initial management, within the first 24 h of admission

The level of inspired oxygen was formally prescribed in 64% (886/1375) of cases (interhospital variation 9–94%, IQR 53–77%). It was more likely to be formally prescribed if the Sa,O2 measured by pulse oximetry was ≤92%. The distinction by level of Pa,O2 was less obvious.

Repeat arterial blood gases were performed in 34%, (371) of cases (interhospital range 0–62%, IQR 19–44%), within 24 h of admission. They were more likely to be repeated in the acidotic patient.

Nebulized bronchodilators were documented as given in 91% (1267/1400) of admissions. A β2‐agonist was used with an anticholinergic in 17% (979/1267) of cases, a β2‐agonist alone in 17% (215) and an anticholinergic alone in 2% (28) whilst in 4% the type was unknown. Systemic steroids and antibiotics were given to the majority of patients.

Assisted ventilation (either invasive positive pressure ventilation (IPPV) or NIPPV) was used in 3% of cases (hospital range 0–11%, IQR 0–5%). Frequency of use was unaffected by first or re-admission but was more likely to be used in the acidotic patient (table 3⇓).

Initial management within 24 h of admission

Continuing management

A chart peak flow record to assess reversibility was kept in only a half of cases and a third overall had neither a peak flow chart or evidence of FEV1 recorded within 5 yrs or 3 months after the admission. Inhaler technique was infrequently assessed and smoking cessation advice rarely given and documented in the case notes. Documentation of vaccination advice recommendation of pulmonary rehabilitation and formal reversibility testing was poor.

In the first time admissions there were higher rates of checking inhaler technique (28 versus 16%) and of giving smoking cessation advice to current smokers (34 versus 28%). For those with previous admissions there were higher rates in the recording of FEV1 (58 versus 47%) reversibility testing (bronchodilators: 29 versus 25%, steroids: 8 versus 6%), vaccination advice (4.9 versus 4.3%) and pulmonary rehabilitation advice (3.2 versus 2.0%). Rates for outpatient follow-up were identical These differences are not unexpected and are of little clinical significance (table 4⇓).

Table 4

Continuing management

A Pa,O2 on admission of <7.3 kPa was documented in 246 cases and few of these had a subsequent Pa,O2 >7.3 kPa whilst breathing room air recorded in the case notes. Eighteen per cent (254) received oxygen when discharged stated as a concentrator in 111 cases and cylinder in 90. This included 68 of the cases with an admission Pa,O2<7.3 kPa.

Out of 797 given outpatient follow-up 57% (458) attended, 23% (181) did not, 8% (66) were readmitted and no information was available for the remaining 12%. At the time of discharge 43% (602/1400) cases were under the care of a Chest Physician, 20% (277) under a Geriatrician and 32% (450 cases) under another speciality physician.

Comparison of respiratory and nonrespiratory specialist care

Respiratory specialists were more likely to record FEV1, chart peak expiratory flow (PEF), check inhaler technique, give smoking cessation advice, prescribe more medications at discharge, and arrange follow-up.

The severity of COPD when a measured FEV1 was available was compared between the two managed groups using a two-sample t‐test. For male cases FEV1 (L) Respiratory specialists 1.07±0.59, nonRespiratory specialists 1.09±0.54 p=0.74, CI −0.1–0.1. FEV1 % pred value 39% and 41% respectively, p=0.43, CI −7–3%. For female cases the more severe cases were biased towards the Respiratory specialists. For example FEV1 Respiratory specialists 0.78±0.38, and non-Respiratory specialists 0.86±0.40 p=0.07, CI −0.2–0.1 L. As % pred, Respiratory specialists 38% and non-Respiratory specialists 47%, p=0.002, CI −14–3% (table 5⇓).

Discussion

This audit of the management of 1,400 cases of COPD admitted to hospitals throughout the UK has demonstrated deficiencies in standards of care measured against the BTS management guidelines as well as wide variations of process of care between hospitals that cannot be explained by known case-mix variables. Nearly half did not have objective confirmation of the diagnosis documented. Investigations recommended to optimize emergency management were often not performed, and later interventions that might influence the prognosis of the disease were not made (tables 3 and 4⇑⇑). Patients who at the time of discharge were under the responsibility of a respiratory specialist were more likely to have the severity of their disease documented, to be receiving more medication at the time of discharge, and to have follow-up arrangements in place (table 5⇑). There are few other published audits of standards of care in COPD with which to compare these findings 8–10 and none as comprehensive, including such large patient numbers and varied sample of hospitals. This current study is unique in measuring process of care against national guidelines for the management of COPD 7. Similar variation in standards of care, has previously been linked to regional differences in outcome and death of patients with COPD 10.

The audit inclusion criterion was a clinical diagnosis of COPD at discharge. The BTS guidelines recommend confirmation of clinical diagnosis by spirometry. Whilst this simple investigation is available in every hospital and the audit protocol accepted an FEV1 recorded within the 5 yrs prior to admission or in the 3 months following admission, only 53% of cases had this documented. In only 37% (514) of all cases was this available as a percentage of the predicted mean value that is used to classify the severity of the condition. Of these 26 (5%) had a value >80% pred i.e. did not have COPD by the BTS criteria but still had this diagnostic label at discharge. The peak expiratory flow was recorded in 46% of cases on admission and a chart record vital to assess therapeutic response was kept in just 51% of cases. A formal reversibility test to bronchodilators or steroids was documented in 27% and 7% of cases respectively. Chest physicians were more likely to have confirmed the diagnosis of COPD than other specialists (71 versus 41% table 5⇑). It is of concern that some clinicians do not appear to accept the need to confirm a clinical impression with a diagnostic test.

Initial assessment

There are a number of investigations recommended in the BTS guidelines that assist in the immediate management of admissions with acute deterioration in COPD. These include arterial blood gas analysis, chest radiograph, and peak flow measurement. These were documented in 79%, 65%, and 46% of cases respectively with wide interhospital variation. For example a comment on the chest radiograph was recorded in 98% of cases in one centre and in no cases in another. Such wide differences points to poor clinical practice or inadequate case note records.

The variability between centres in recording arterial blood gas analysis was 40–100% (IQR 73–90%) A formal prescription specifying inspired oxygen level was documented in only 64% of cases with a huge interhospital variation (9–94% IQR 53–77%). Type II respiratory failure is a fairly common and treatable sequel to acute exacerbations of COPD however, of those with acidosis and hypercapnoea, over one-third failed to receive follow-up arterial blood gas analysis to monitor progress and only 13% received ventilatory support. This failure of management may suggest a nihilistic approach and occurred in spite of the good evidence that even in severe COPD the outcome following interventions for acute deteriorations is good 11.

Long-term planning

Long-term oxygen therapy and smoking cessation are proven interventions that may extend life expectancy in patients with COPD 12–15. A Pa,O2<7.3 kPa was recorded in 246 cases at admission but only 15 of these (6%) had a subsequent recorded Pa,O2 of >7.3 kPa whilst breathing room air during the recovery phase of their admission or at subsequent clinic follow-up. Sixty-eight of the 246 were discharged on home oxygen and may have had prior oxygen assessments but no further investigation was made in the remaining 66%. Smoking cessation advice was formally recorded as given in just 30% of current smokers and 11% of those who claim to have stopped within the preceding 3 months and who are known to be at serious risk of relapse. There is good evidence that smoking cessation strategies involving combinations of nicotine replacement greatly enhance success and should be made known to patients 16. Whilst such advice may have been previously offered, these examples suggest less than optimal intervention care by physicians.

Comparison with other studies

Previous studies 8, 17, 18 in the management of patients with COPD and asthma have suggested respiratory specialists are more likely to provide better care than nonrespiratory medical specialists. This audit confirms these findings (table 4⇑). Nevertheless patients under the care of chest teams still received care that appears to fall short of the optimum.

There are limitations to this study that require discussion. A high proportion of admissions were not the first inpatient episode for these cases and some of the absent documentation of interventions may have been made previously. A retrospective audit of case notes will inevitably contain some inaccuracies and depends upon the case note recording by doctors. In medico-legal terms absence of documentation implies absence of process. Quality of collected data depended upon those completing the audit forms and several levels of control were instituted. The power of the study comes from the large sample size and the number and variety of contributing centres. Results from this study will help to form a future COPD audit tool which will be brief and have easily collectable data, reproducible from one hospital centre to another, designed for routine prospective use in hospital medical departments.

Implications for the future

The fact that some hospitals do achieve highly when assessed against the BTS guidelines shows that targets are practical and attainable. Attention should be focused on disseminating good practise and examining reasons for poor process in hospitals with lower achievements. Better process may be a surrogate forbetter outcomes 19, 20 and process itself may be used as a surrogate of outcome in chronic medical disorders 21.

These data reflect the performance of hospitals and not of individuals. Each hospital in this audit received an individual report showing its performance against national averages. This form of benchmarking can be easily understood by medical and nonmedical staff 22. Poorly performing units should examine data recording, staffing, organizational issues as well as management protocols and clinical competence.
