Development of indicators for patient-centred cancer care.

PURPOSE: Assessment of current practice with a valid set of indicators is the key to successfully improving the quality of patient-centred care. For improvement purposes, we developed indicators of patient-centred cancer care and tested them on a population of patients with non-small cell lung cancer (NSCLC). METHODS: Recommendations for patient-centred care were extracted from clinical guidelines, and patients were interviewed to develop indicators for assessing the patient-centredness of cancer care. These indicators were tested with regard to psychometric characteristics (room for improvement, applicability, discriminating capacity and reliability) on 132 patients with NSCLC treated in six hospitals in the east Netherlands. Data were collected from patients by means of questionnaires. RESULTS: Eight domains of patient-centred cancer care were extracted from 61 oncology guidelines and 37 patient interviews and were translated into 56 indicators. The practice test amongst patients with NSCLC showed the most room for improvement within the domains 'emotional and psychosocial support', 'physical support' and 'information supply'. Overall, 26 of the 56 indicators had good psychometric characteristics. CONCLUSIONS: Developing a valid set of patient-centred indicators is a first step towards improving the patient centredness of cancer care. Indicators can be based on recommendations from guidelines, but adding patient opinions leads to a more complete picture of patient centredness. The practice test on patients with NSCLC showed that the patient centredness of cancer care can be improved. Our set of indicators may also be useful for future quality assessments for other patients with cancers or chronic diseases.

Learning curve of conventional transbronchial needle aspiration in pulmonologists experienced in bronchoscopy.

BACKGROUND: Despite its proven efficacy, transbronchial needle aspiration (TBNA) remains an underutilized technique for sampling enlarged mediastinal lymph nodes in the staging of lung cancer. Previous investigators have reported on TBNA experience, but without mentioning individual learning curves related to lymph node size in pulmonologists experienced in bronchoscopy. OBJECTIVES: The aim of this study was to evaluate the TBNA learning curve in a group of pulmonologists already experienced in bronchoscopy, and to relate their yields to lymph node size and location. METHODS: Data on TBNA yield and related lymph node size were collected retrospectively for five individual pulmonologists. RESULTS: The diagnostic yield of five pulmonologists who started to perform TBNA was evaluated over the first 32 months. TBNA was performed on 138 lymph nodes in 119 patients. The overall diagnostic yield was 77% (range 67-91%). The average diagnostic yield increased from 77% at the start of the learning curve to 82% after 32 months of experience. It was related to lymph node size, but not to lymph node location. The average lymph node size was 22 mm. CONCLUSIONS: Satisfactory results were obtained immediately after introduction of TBNA in the bronchoscopy workup. There is no significant TBNA learning curve. The diagnostic yield was related to lymph node size but not to lymph node location.

Quality of integrated care for patients with nonsmall cell lung cancer: variations and determinants of care.

BACKGROUND: In the current study, the authors focused on determinants influencing the quality of care and variations in the actual quality of integrated care for patients with nonsmall cell lung cancer (NSCLC) to estimate whether there is room for improvement. METHODS: The authors tested the quality of integrated care for 276 NSCLC patients with 14 quality indicators of professional (4 indicators), organizational (3 indicators), and patient-oriented quality (7 indicators). Patient characteristics and actual care data were derived from medical record data, patient-oriented care was derived from patient questionnaires, and professional and hospital characteristics were derived from questionnaires for professionals. The performance measure was the proportion of patients to whom the indicator applied who had positive scores on the indicator. Multilevel logistic regression analysis determined the influence of patient, professional, and hospital characteristics on care. RESULTS: With regard to professional quality, the proportions of patients who underwent fluorodeoxyglucose-positron emission tomography or cervical mediastinoscopy according to the guideline criteria were 88% and 84%, respectively. Only 50% of the biopsies were adequately obtained during mediastinoscopy, and in 3% of the patients with clinical stage III disease (based on the TNM classification) there was a search for brain metastases before the initiation of combination therapy. With regard to organizational quality, the diagnostic route of 79% of the patients was completed within 21 days; 51% of patients began therapy within 35 days and 57% were discussed during multidisciplinary consultation. All but 1 patient-oriented quality indicator scored /=20% with regard to 11 of the 14 indicators. The patient-related determinants "stage of disease," "age," and "comorbidity" were found to influence the indicator scores the most. CONCLUSIONS: The quality of integrated care (especially patient-oriented care) for NSCLC patients needs improvement. Patient characteristics appear to influence performance more than professional or hospital characteristics.

Diagnostic yield of transbronchial histology needle aspiration in patients with mediastinal lymph node enlargement.

BACKGROUND: Transbronchial needle aspiration (TBNA) is a safe, minimally invasive technique to assess the mediastinal spread of lung cancer. Excellent results have been published by experts. However, little information is available about the diagnostic yield of TBNA with the histology needle in a non-expert center. OBJECTIVES: The aim of this study is to assess the diagnostic yield of histology TBNA in the workup of suspected lung cancer. METHODS: In a non-university teaching hospital, TBNA data from patients diagnosed with lung cancer between June 1998 and July 2000 were analyzed retrospectively. TBNA had been performed by six different bronchoscopists in patients eligible for surgery with accessible N2 and N3 lymph nodes on computed tomography of the chest during the workup of an undefined mass. Cytology and histology specimens were obtained with the same 19-gauge needle. TBNA results were considered to be diagnostic if cytologic or histologic examination revealed a malignant lesion or non-malignant lymphoid cells. However, TBNA outcome was called non-diagnostic if no representative cells were obtained. RESULTS: From a group of 264 consecutive lung cancer patients, 106 (40%) patients were eligible for TBNA. In 79%, TBNA was diagnostic in cytology and/or histology specimens. Malignancy was demonstrated in 59% (63/106). In only 32/106 patients (30%), a histologic core of tissue could be sampled. In 87.5% of these patients (28/32), TBNA was diagnostic. For cytology only, this number was slightly lower (75%, 56/74). In 12 cases, diagnostic TBNA was verified by mediastinoscopy: these diagnoses were concordant. The sensitivity is 65% if all non-confirmed cases are considered false negative. Ten mediastinoscopies were avoided because TBNA demonstrated contralateral N2 (= N3) disease. The routine use of TBNA during bronchoscopy in suspected N2 disease is a cost-effective procedure, as the total additional costs of TBNA (9,540 EUR) were lower than the costs of 10 avoided mediastinoscopies (15,500 EUR). No complications were observed. CONCLUSION: The diagnostic yield of TBNA relied mainly on cytology specimens, despite the use of a histology needle. Representative histology specimens could only be obtained in 28/106 patients (26%). Since TBNA was performed in a general hospital by different bronchoscopists, this procedure is useful in the workup of lung cancer patients with enlarged lymph nodes.
