  Hide Detailed Description

Detailed Description:

By taking advantage of a randomized roll-out design of the PPIA program in Mumbai, this evaluation aims to determine the causal effects of the program on quality of care among private sector health providers. The evaluation is embedded in an existing quality of care surveillance project that uses standardized patients to assess the quality of tuberculosis (TB) care in Mumbai, India. Below is a description of (1) the TB intervention implemented by the PPIA, (2) the quality of TB care (QuTUB) surveillance project, and (3) the randomized roll-out of the PPIA program among a subset of providers in order to isolate the impact of the program on quality of care.

The entire program and its implementation are external to the researchers. To better understand the impact of the program using an already approved surveillance study, the researchers use a stepped-wedge design that involves a sequential roll-out of the program to a subset of providers over a period of time where the order of roll-out is randomized.

  1. PPIA intervention: Between January 2014 and December 2016, the pilot PPIA program was independently implemented by the non-governmental organization PATH (Program for Appropriate Technology in Health as it is known formerly) in Mumbai city. In its role as the PPIA in Mumbai, PATH's aim is to strengthen existing efforts to control TB through engagement of the private health sector. Through this network, the objectives are to facilitate early and accurate diagnosis with proper notification of cases and to ensure appropriate treatment and treatment adherence to completion among TB patients in the private sector. In order to achieve these objectives, the PPIA initiated and expanded a private sector network based on a hub-and-spoke model. Hubs are generally private health facilities ("hubs" with an MD Chest Physician and access to a pharmacy and digital X-ray laboratory) and private clinics of MD and MD Chest Physicians. Spokes are generally doctors with a Bachelor of Medicine, Bachelor of Surgery (MBBS) degree, practitioners of alternative medicines (AYUSH practitioners who are trained Ayurveda, Yoga and Naturopathy, Unani, Siddha, or Homeopathy), and informal providers with minimum or no qualifications. The PPIA network also includes chemists/pharmacists and diagnostic laboratories. The pilot in Mumbai will serve as a model for private health sector involvement in national TB control and will be used to inform similar programs nearby and in other urban Indian settings.
  2. Quality of care surveillance: The QuTUB project is a part of the PPIA monitoring efforts and runs in parallel to the programs' scale up and expansion. The objective of the QuTUB project is to capture levels of quality of care through standardized patients ("mystery shoppers" or "fake patients"), who are individuals recruited locally and trained to portray four different TB cases. Developed by a Technical Advisory Group and benchmarked against the Standards of TB Care of India, the cases were designed to reflect different stages of TB disease progression, some with previous interactions with the health system upon presentation to a health care provider. Outcomes captured by the standardized patients through an exit questionnaire given to them within 2 hours of their interaction with providers` include: history questions asked by the provider, laboratory tests ordered, medicines dispensed or prescribed, and referrals made.
  3. Randomized roll-out evaluation approach: In January 2015, PATH was interested in trying to further understand the causal impact of their program on diagnostic processes, and there was an opportunity to remove the selection bias and attribute differences in quality of care solely to the program by taking advantage of a randomized roll-out expansion plan of the PPIA program among a subset of providers. In collaboration with the PPIA Mumbai team, this study takes an intention-to-treat and instrumental variables evaluation approach through selective enrollment of a subset of providers in the second round of program scale-up in Mumbai city. The researchers note that the subset of providers are those who were not purposively selected in the earlier round of enrollment and therefore may be those who see fewer TB patients, or those who were reluctant to enroll into the program during the first rounds of program expansion. Therefore, the impact of the program on this group may be different from among those who were enrolled previously. Under this approach, it was agreed that for the evaluation eligible AYUSH practitioners would be networked in two purposively selected high TB burden or high slum population wards in Mumbai. For this, the researchers provided PATH with a list of 300 randomly selected practitioners among those who were not already networked into the program. AYUSH practitioners on this list were randomly allocated to two groups: one group (treatment) of 150 eligible AYUSH would be sensitized and networked, and the other group (control) of 150 eligible AYUSH would not be approached for networking after a year or more, when the QuTUB study team is able to complete end-line data collection in 2016. Selection into program roll-out groups was randomized. Standardized patients are sent to both groups before any intervention for baseline measures of quality of care, and the standardized patients would return again before the control group begins to receive the intervention for an end-line measure. The entire intervention in Mumbai is implemented by the PPIA and is separate from the team implementing the quality of care surveillance and evaluation. Care is taken to ensure that the evaluation team will be in the field independently of the implementation.

Analysis:

Intention-to-treat analysis and instrumental variables will be conducted after determining (i) that the treatment assignment can serve as a good instrument by: a strong correlation to the actual enrollment statuses of the providers regardless of treatment assignment, being uncorrelated with the outcomes, and only being connected to the outcomes through actual enrollment in the program, and (ii) balance at baseline between the treatment and control groups.

Arm Intervention/treatment
Experimental: Tuberculosis Program (PPIA)
Half of the 300 participants were randomly selected to be sensitized and engaged into the program, and subsequently to receive the benefits of the PPIA intervention. Providers in the PPIA arm if networked into the program will receive the benefits of the program, including but not limited to: ability to provide presumptive TB patients and TB cases vouchers for free and/or subsidized diagnostic testing and referrals to providers for free first line anti-TB treatment (TB cases only); reimbursements for subsidized tests; training opportunities, and access to a referral network.
Other: Tuberculosis Program
The intervention includes a variety of (1) non-financial incentives that are intended to reduce clinical and financial costs for presumptive TB patients and TB cases for diagnostic testing and treatment (free digital chest X-ray, free sputum microscopy, free or subsidized drug-susceptibility testing, free first-line anti-TB treatment) within the PPIA network, and (2) training or certified medical education (CME) sessions for the providers from the PPIA. Meanwhile, program marketing, CMEs, and other advocacy efforts are aimed to raise awareness in the communities.
Other Name: Private Provider Interface Agency Program

No Intervention: No Tuberculosis Program (Non-PPIA)
The remaining half of the sample in Mumbai selected randomly will be phased into the program at least a year after the PPIA arm. However, during the year of the study, they will not be networked into the program.



Primary Outcome Measures :
  1. Correct case management [ Time Frame: one year ]
    Correct case management is defined as the proportion of interactions (across all standardized patient (SP) cases) or proportion of providers (by SP case) in which providers managed the case according to the Standards for Tuberculosis Care in India (STCI) within the PPIA program vs. outside the PPIA. Depending on the SP case, the outcome is an index composed of actions a provider did during the interaction with the SP: correct diagnostic tests ordered, correct or harmful treatment prescribed, or referral to a qualified health care provider. These details are extracted from an exit questionnaire that is completed by the SP within 2 hours of the interaction.


Secondary Outcome Measures :
  1. Essential history checklist [ Time Frame: one year ]
    Essential history checklist is defined as the average proportion of essential history questions asked by the practitioner during an interaction for tuberculosis benchmarked against the Standards of Tuberculosis Care in India guidelines. These details are extracted from an exit questionnaire that is completed by the SP within 2 hours of the interaction.

  2. Referral for further management [ Time Frame: one year ]
    Referral for further management is defined as the proportion of interactions in which the provider refers the simulated patient to a qualified provider or another facility and the name, if specified to the SP. These details are extracted from an exit questionnaire that is completed by the SP within 2 hours of the interaction.

  3. Suspicion of tuberculosis [ Time Frame: one year ]
    Suspicion of tuberculosis is defined as the proportion of interactions in which the provider mentions tuberculosis or states that the simulated patient has tuberculosis. These details are extracted from an exit questionnaire that is completed by the SP within 2 hours of the interaction.

  4. Initiation of TB treatment [ Time Frame: one year ]
    Initiation of TB treatment is defined as the proportion of interactions in which the provider initiates the simulated patient on TB treatment. After each interaction, the SP purchases any medicines ordered by the provider. These details are collected on an exit questionnaire; active ingredients are investigated; and medicines are coded separately by two clinicians on the research team.

  5. Number of lab tests ordered [ Time Frame: one year ]
    Number of lab tests ordered is defined as the average number of lab tests ordered per interaction by providers. These details are extracted from an exit questionnaire that is completed by the SP within 2 hours of the interaction.

  6. Lab tests ordered [ Time Frame: one year ]
    Lab tests ordered is defined as the proportion of interactions in which the provider orders specific TB diagnostic tests (e.g. chest X-ray, sputum acid-fast bacillus (AFB) testing, GeneXpert) or other types of tests for the simulated patient. These details are extracted from an exit questionnaire that is completed by the SP within 2 hours of the interaction.

  7. Number of medicines [ Time Frame: one year ]
    Number of medicines is defined as the average number of medicines ordered per interaction. After each interaction, the SP purchases any medicines ordered by the provider. These details are collected on an exit questionnaire; active ingredients are investigated; and medicines are coded and categorized by two clinicians on the research team.

  8. Medicine type [ Time Frame: one year ]
    Medicine type is defined as the types of medicines ordered (e.g., antibiotics, steroids, fluoroquinolones, and others) during the simulated patient interactions. After each interaction, the SP purchases any medicines ordered by the provider. These details are collected on an exit questionnaire; active ingredients are investigated; and medicines are coded and categorized by two clinicians on the research team.

  9. Rates of case registration [ Time Frame: one year ]
    Rates of case registration is defined as the proportion of interactions in which providers who are networked in the PPIA program registers the simulated patient into the program. These details are extracted from an exit questionnaire that is completed by the SP within 2 hours of the interaction.

  10. Vouchers received [ Time Frame: one year ]
    Vouchers received is defined as the proportion of PPIA vouchers or referral coupons given to the simulated patient for any of the actions that could have resulted in a voucher or referral coupon only among providers who are in the PPIA program. These details are extracted from an exit questionnaire that is completed by the SP within 2 hours of the interaction.

  11. Patient costs [ Time Frame: one year ]
    Patient costs is defined as the average amount charged to the simulated patients by providers per interaction for the entire visit. These details are extracted from an exit questionnaire that is completed by the SP within 2 hours of the interaction.

  12. Consultation, medicine, and test costs to patients [ Time Frame: one year ]
    The outcome for consultation, medicine, and test costs to patients is defined as the average amount charged for consultation, medicines, and tests (if itemized) by providers per interaction. These details are extracted from an exit questionnaire that is completed by the SP within 2 hours of the interaction.
