BACKGROUND

In 2013-2014, we achieved 89% adult HIV testing coverage using a hybrid testing approach in 32 communities in Uganda and Kenya (SEARCH: NCT01864603). To inform scalability, we sought to determine: (1) overall cost and efficiency of this approach; and (2) costs associated with point-of-care (POC) CD4 testing, multidisease services, and community mobilization.

METHODS

We applied microcosting methods to estimate costs of population-wide HIV testing in 12 SEARCH trial communities. Main intervention components of the hybrid approach are census, multidisease community health campaigns (CHC), and home-based testing for CHC nonattendees. POC CD4 tests were provided for all HIV-infected participants. Data were extracted from expenditure records, activity registers, staff interviews, and time and motion logs.

RESULTS

The mean cost per adult tested for HIV was $20.5 (range: $17.1-$32.1) (2014 US$), including a POC CD4 test at $16 per HIV+ person identified. Cost per adult tested for HIV was $13.8 at CHC vs. $31.7 by home-based testing. The cost per HIV+ adult identified was $231 ($87-$1245), with variability due mainly to HIV prevalence among persons tested (ie, HIV positivity rate). The marginal costs of multidisease testing at CHCs were $1.16/person for hypertension and diabetes, and $0.90 for malaria. Community mobilization constituted 15.3% of total costs.

CONCLUSIONS

The hybrid testing approach achieved very high HIV testing coverage, with POC CD4, at costs similar to previously reported mobile, home-based, or venue-based HIV testing approaches in sub-Saharan Africa. By leveraging HIV infrastructure, multidisease services were offered at low marginal costs.

OBJECTIVE

Electronic clinical quality measures (eCQMs) rely on computer algorithms to extract data from electronic health records (EHRs). On behalf of the American College of Rheumatology (ACR), we sought to develop and test eCQMs for rheumatoid arthritis (RA).

METHODS

Drawing from published ACR guidelines, a working group developed candidate RA process measures and subsequently assessed face validity through an interdisciplinary panel of health care stakeholders. A public comment period followed. Measures that passed these levels of review were electronically specified using the quality data model, which provides standard nomenclature for data elements (category, datatype, and value sets) obtained through an EHR. For each eCQM, 3 clinical sites using different EHR systems tested the scientific feasibility and validity of measures. Measures appropriate for accountability were presented for national endorsement.

RESULTS

Expert panel validity ratings were high for all measures (median 8-9 of 9). Health system performance on the eCQMs was 53.6% for RA disease activity assessment, 69.1% for functional status assessment, 93.1% for disease-modifying antirheumatic drug (DMARD) use, and 72.8% for tuberculosis screening. Kappa statistics, which evaluated whether the eCQM validly captured data obtained from manual EHR chart review, demonstrated moderate to substantial agreement (0.54 for functional status assessment, 0.73 for tuberculosis screening, 0.84 for disease activity, and 0.85 for DMARD use).

CONCLUSION

Four eCQMs for RA have achieved national endorsement and are recommended for use in federal quality reporting programs. Implementation and further refinement of these measures is ongoing in the ACR's registry, the Rheumatology Informatics System for Effectiveness (RISE).

BACKGROUND

Physician Orders for Life-Sustaining Treatment (POLST) forms are used to document patient treatment preferences as medical orders. Prior research demonstrates that use of POLST alters medical treatments in a way that is consistent with the POLST orders. However, there are minimal data about the quality of POLST decisions, including whether they reflect the current preferences of well-informed patients.

OBJECTIVE

Evaluate the quality of POLST decisions.

DESIGN

Chart abstraction; interviews.

SUBJECTS

Nursing home residents and healthcare agents of incapacitated nursing home residents (n = 28).

MEASUREMENTS

Characteristics of the POLST conversation were assessed. Brief vignettes were used to assess knowledge about how POLST orders guide medical treatment. Current treatment preferences were elicited and compared with the patient's POLST orders to assess discordance.

RESULTS

A majority (59%) of participants recognized the POLST form. Participants were generally accurate in their knowledge of how POLST orders guide treatment concerning cardiopulmonary resuscitation (CPR) (68%), antibiotics (74%), and artificial nutrition (79%), but less so for medical interventions (50%). Current treatment preferences were initially discordant with one or more POLST orders for 64% (18/28) of participants, but half of these discordances were resolved with further discussion (e.g., participant agreed with the existing order). Discordance by treatment decision was as follows: CPR (7%), level of medical intervention (18%), antibiotics (21%), and artificial nutrition (11%).

CONCLUSIONS

Discordance between current preferences and POLST orders is complex. Interventions are needed to support high-quality POLST decisions that are informed and concordant with current preferences.

CONTEXT

Measuring What Matters (MWM) prioritizes quality measures in palliative care practice. Hematologic malignancy patients are less likely to access palliative care, yet little is known about their unique needs. Differences in MWM adherence may highlight opportunities to improve palliative care in hematology.

OBJECTIVES

To assess adherence to MWM measures by palliative care clinicians caring for patients with hematologic malignancies, compared to those with solid tumors.

METHODS

We used the Quality Data Collection Tool to assess completion of MWM measures across nine sites.

RESULTS

We included data from 678 patients' first visits and various care settings; 64 (9.4%) had a hematologic malignancy, whereas 614 (90.6%) had a solid tumor. Hematology patients were more likely to be seen in a hospital (52 or 81.3% vs. 420 or 68%), whereas solid tumor patients were more frequently seen at home or in clinics (160 or 26% vs. 7 or 10.9%). Of the nine MWM measures we assessed, high adherence (>90%) was seen regardless of tumor type in measures #3 (Pain Treatment), #7 (Spiritual Concerns), #8 (Treatment Preferences), and #9 (Care Consistent With Preferences). Clinicians seeing hematology patients were significantly less likely to meet measures #2 (Screening for Physical Symptoms; 57.8% vs. 84.2%, P < 0.001), and #5 (Discussion of Emotional Needs; 56.3% vs. 70.0%, P = 0.03).

CONCLUSION

MWM adherence regarding symptom assessment and meeting emotional needs was lower for patients with hematologic malignancies compared to those with solid tumors. This finding suggests two key areas for quality improvement initiatives in palliative care for patients with hematologic malignancies.

Ibrutinib, a potent and irreversible small-molecule inhibitor of both Bruton's tyrosine kinase and interleukin-2 inducible kinase (ITK), has been used to treat relapsed/refractory chronic lymphocytic leukemia (CLL) with prolongation of progression-free and overall survival. Here, we present 27 patients with relapsed CLL following allogeneic hematopoietic cell transplant (HCT) who subsequently received ibrutinib salvage therapy. Sixteen of these patients were part of multi-institutional clinical trials and achieved an overall response rate of 87.5%. An additional 11 patients were treated at Stanford University following US Food and Drug Administration approval of ibrutinib; 7 (64%) achieved a complete response, and 3 (27%) achieved a partial response. Of the 9 patients treated at Stanford who had mixed chimerism-associated CLL relapse, 4 (44%) converted to full donor chimerism following ibrutinib initiation, in association with disease response. Four of 11 (36%) patients evaluated by ClonoSeq achieved minimal residual disease negativity with CLL <1/10 000 white blood cells, which persisted even after ibrutinib was discontinued, in 1 case even after 26 months. None of the 27 patients developed graft-versus-host-disease (GVHD) following ibrutinib initiation. We postulate that ibrutinib augments the graft-versus-leukemia (GVL) benefit through a T-cell-mediated effect, most likely due to ITK inhibition. To investigate the immune modulatory effects of ibrutinib, we completed comprehensive immune phenotype characterization of peripheral B and T cells from treated patients. Our results show that ibrutinib selectively targets pre-germinal B cells and depletes Th2 helper cells. Furthermore, these effects persisted after drug discontinuation. In total, our results provide evidence that ibrutinib effectively augments GVL without causing GVHD.
