Public-private mix for TB care in India: Concept, evolution, progress

Exploring private sector perspectives on barriers and facilitators in availing tuberculosis care cascade services: a qualitative study from the Indian state

INTRODUCTION

The private sector plays an important role in tuberculosis (TB) elimination by providing access to quality TB care services like diagnosis and treatment, advocacy for preventive measures, innovation to address challenges in TB elimination, vaccines etc. The study aims to understand the perspectives of private practitioners on patients' TB care cascade to reinforce existing interventions by assuring the quality of care to TB patients.

METHODS

The study utilized a qualitative design through in-depth interviews of private practitioners and was conducted in Ranchi and Purbi Singhbhum District of Jharkhand State from March-August 2021. The pilot-tested, semi-structured, open-ended interview guide questionnaire collected information from private practitioners on various aspects of the TB care cascade. The data from the provider interviews were transcribed into multiple codes and themes on the TB program. An inductive analysis was carried out with a focus on content credibility to eliminate bias. Ethical approval was received from the Institutional Ethics Committee of the Indian Institute of Public Health Gandhinagar (IIPHG), India. Written consent was taken from the private practitioners involved in the study.

RESULT

In-depth interviews of 17 private practitioners reveal various factors contributing to delays in TB care cascades, especially delay in access to TB diagnosis and TB Care, delay in providing treatment once after diagnosis and poor adherence to the TB treatment. According to the perception of private practitioners, there was an array of client, provider and system side factors affecting the TB care cascade gaps positively and negatively. Positive aspects mainly emerged from interviews: strong governance, consistent supply chain management, innovative PPP models and financial schemes reducing out-of-pocket expenditure (OOPE). Various factors affecting the TB care cascade negatively include awareness among the patient, socio-economic status, approach and decision-making power of providers, adverse effects of drugs, staff capacity building, etc. CONCLUSIONS: Engaging private practitioner in TB elimination efforts is critical to achieving global targets and reducing the burden of TB. The study helps to determine geography-specific barriers and facilitators of the TB care cascade to achieve the aim of providing universal access to TB healthcare with the inclusion of private practitioners.

Effect of public-private interface agency in Patna and Mumbai, India: Does it alter durations and delays in care seeking for drug-sensitive pulmonary tuberculosis?

Background: Public–private interface agency (PPIA) intervention models in Patna (E. India) and Mumbai (W. India) for pulmonary drug-sensitive (DS) tuberculosis (TB) patients were evaluated over 2 years after maturity to examine effect on reduction of patient pathways and retention.  The models engaged private providers, diagnostic facilities and pharmacies into an effective network providing free diagnostic tests and treatment.

Methods: A population-based retrospective study was undertaken to assess effectiveness of the PPIA model in care pathways of 64 (Patna) and 86 (Mumbai) patients through in-depth interviews conducted within 6 months of initiation treatments to identify types and facilities accessed, duration to diagnosis and treatment. Median durations based on facilities accessed were statistically analysed.  Comparisons were made with baseline values and endline pathways of patients accessing PPIA engaged/non-engaged facilities in private and public sectors.

Results: Compared to non-engaged facilities, persons accessing engaged facilities at first point-of-care had shorter pathways (Mumbai: 32 vs 43 days), (Patna: 15 vs 40 days).  Duration for first care-seeking was considerably shorter for patients accessing PPIA in Patna and for both engaged and non-engaged private facilities in Mumbai (4 days).  Whilst PPIA engaged facilities diagnosed more cases than others, the RNTCP in Mumbai provided diagnosis early.  There was good retention of patients by PPIA-engaged (1 ^st) facilities (90% post-diagnosis in Patna) but this was affected by the hub-spoke referral system in Mumbai (13%). Second diagnosis is a common feature in Mumbai.  The spoke-hub model in Mumbai contributed considerably to treatment delay; PPIA-engaged providers were better at retaining patients post treatment initiation 11/25 (44%).

Conclusion: PPIA-engaged facilities, accessed at onset, result in marked reduction in pathway durations.  Such initiatives should engage a critical mass of competent providers, proximal investigation facilities with enhanced disease awareness and literacy efforts amongst communities.  Patient movement should be minimized for early treatment and retention.
