Quality Gaps and Comparative Effectiveness of Management Strategies for Recurrent Malignant Pleural Effusions.

ABSTRACT:

Background

Guidelines for recurrent malignant pleural effusions (MPEs) recommend definitive procedures, such as indwelling pleural catheters (IPCs) or pleurodesis, over repeat thoracentesis. We hypothesized that many patients have multiple thoracenteses rather than definitive procedures and that this results in more procedures and complications.

Methods

Retrospective cohort study using SEER-Medicare data from 2007 to 2011. Patients 66 to 90 years of age with an MPE were included. The primary outcome was whether patients with rapidly recurring MPE, defined as recurrence within 2 weeks of first thoracentesis, received guideline consistent care. Guideline consistent care was defined as a definitive second pleural procedure.

Results

Thoracentesis for MPE was performed in 23,431 patients. A second pleural procedure because of recurrence was required in 12,967 (55%). Recurrence was rapid in 7,565 (58%) of the 12,967 patients that had a recurrence. Of the 7,565 patients with rapid recurrence, 1,811 (24%) received guideline consistent care. Definitive pleural procedures compared with repeat thoracentesis resulted in fewer subsequent pleural procedures (0.62 vs 1.44 procedures per patient, respectively; P < .0001), fewer pneumothoraxes (< 0.0037 vs 0.009 pneumothoraxes per patient, respectively; P = .001), and fewer ED procedures (0.02 vs 0.04 ED procedures per patient, respectively; P < .001). Repeat thoracentesis and IPCs resulted in fewer inpatient days compared with chest tube or thoracoscopic pleurodesis (0.013 vs 0.013 vs 0.085 vs 0.097 inpatient days per day of life, respectively; P < .001).

Conclusions

Guideline consistent care using definitive procedures compared with repeat thoracentesis was associated with fewer subsequent procedures and complications; however, pleurodesis resulted in more inpatient days.

Project description:IntroductionPleural effusions frequently signal disseminated cancer. Diagnostic markers of pleural malignancy at presentation that would assess cancer risk and would streamline diagnostic decisions remain unidentified.MethodsA consecutive cohort of 323 patients with pleural effusion (PE) from different etiologies were recruited between 2013 and 2017 and was retrospectively analyzed. Data included history, chest X-ray, and blood/pleural fluid cell counts and biochemistry. Group comparison, receiver-operator characteristics, unsupervised hierarchical clustering, binary logistic regression, and random forests were used to develop the malignant pleural effusion detection (MAPED) score. MAPED was validated in an independent retrospective UK cohort (n = 238).ResultsFive variables showed significant diagnostic power and were incorporated into the 5-point MAPED score. Age > 55 years, effusion size > 50% of the most affected lung field, pleural neutrophil count 〈 2,500/mm3, effusion protein 〉 3.5 g/dL, and effusion lactate dehydrogenase > 250 U/L, each scoring one point, predicted underlying cancer with the area under curve(AUC) = 0.819 (P < 10-15) in the derivation cohort. The integrated discrimination improvement of MAPED scores showed an increase compared to cytology (p <0.001). Decision curve analysis indicated that the MAPED score generated net clinical benefit. In the validation dataset, the AUC of MAPED scores was 0.723 ( P = 3 × 10-9) for the MAPED score. Interestingly, MAPED correctly identified 33/42(79%) of cytology-negative patients that indeed had cancer.ConclusionsThe MAPED score identifies malignant pleural effusions with satisfactory accuracy and can be used complementary to cytology to streamline diagnostic procedures.Condensed abstractDiagnostic markers for malignant pleural effusions remain uncertain. The MAPED score identifies malignant pleural effusions and complements cytology and confers no additional risk to the patient or cost to the healthcare system.
