Medical Missions in Remote Philippine Communities

This video highlights the critical work of Dr. Heidi Sampang and her team in bringing healthcare to the most remote corners of the Philippines, where access to medical professionals is severely limited. The narrative focuses on two distinct missions: one to the village of Garaya in Northern Samar and another to Basilan province.

Mission to Garaya, Northern Samar

1. The Challenge of Access:

• The village of Garaya is only accessible via a three-hour boat ride on the Pambujan River, followed by a four-hour trek on foot.
• This arduous journey necessitates the support of over 50 soldiers who assist in carrying essential equipment and supplies for the 10 doctors and medical support staff.
• Dr. Sampang is the first doctor to lead a medical team to this village, which serves a target population of approximately 2,000 people from four barangays.
• The primary reason for the mission is the lack of access to healthcare, with some communities in the region having never seen a doctor.

2. Healthcare Delivery and Diagnosis:

• A school is transformed into a two-day field clinic.
• Common ailments treated include super bacterial infections and microbial infections, with prescriptions for antibiotics typically lasting 7 to 10 days.
• Northern Samar is identified as one of the poorest provinces, facing challenges with infrastructure, clean water, and electricity.

3. The Threat of Tuberculosis (TB):

• Tuberculosis is identified as the deadliest invisible threat in these remote areas.
• The Philippines has one of the highest TB rates globally, with six out of every 1,000 individuals affected, and this region is particularly hard-hit.
• Contributing factors include weakened immune systems due to poverty and malnutrition, limited healthcare access, and high population density.
• Many residents in these remote areas do not seek consultation for potential TB symptoms, making early detection difficult.
• Samples for TB testing must be sent to a lab seven hours away, delaying diagnosis and treatment.
• Key Statistic: Without treatment, half of all TB cases lead to death.
• Key Statistic: Six out of every 1,000 individuals in the Philippines are affected by TB.

4. Technological Intervention: Cargo Drones for Sample Transport:

• Dr. Sampang's initiative to use technology began six years prior with the idea of using cargo drones to transport samples for testing.
• Case Study/Example: A test flight was conducted from Sylvino Lobos, involving a complex route over rivers and mountainous terrain, taking approximately 14 minutes for a round trip.
• Drone Capabilities: Drones can carry medicines, antibiotics, and vaccines, and travel at high speeds. They can also facilitate the transport of TB testing samples, eliminating the need for patients to travel long distances.
• Challenges Encountered:
  • The initial drone model proved difficult to operate, even for an experienced pilot, due to strong winds.
  • The drone was deemed too dangerous for populated areas and too challenging to operate without a professional.
  • Despite these operability issues, the drone successfully transported the sputum sample, and lab results were expected within a day, significantly faster than the traditional method.
• Future Drone Development: Dr. Sampang is seeking new, fully autonomous drone models that are smaller, more compact, resilient, affordable, and capable of flying in strong winds and extreme weather conditions over a 7 km range.

Mission to Basilan Province

1. Security Concerns and Context:

• The mission to Basilan is undertaken amidst heightened security concerns following the deaths of two Philippine army soldiers and two civilians in an attack by a Muslim rebel group.
• Basilan is a small island province in the southern Philippines known for past attacks by terrorist groups since the 1990s.
• The medical team, consisting of 11 members, requires an armed military escort for a two-hour car journey to reach the village of Unaya Pukan.
• The Abu Sayyaf group, a Muslim extremist group, has historically caused fear and havoc in the community, necessitating strict safety protocols for the volunteers, including immediate compliance with military instructions.

2. Volunteerism and Motivation:

• The medical missions are largely funded through donations, and volunteers often cover their own personal expenses, including airfare and accommodation.
• Dr. Sampang emphasizes that her efforts are not enough and relies heavily on the selflessness and dedication of her volunteers, calling them the "heart of this organization."
• The volunteers are driven by a passion to address health disparities and deliver high-quality medical services, even in stressful and conflict-affected areas.
• Dr. Sampang finds personal rejuvenation through surfing, which she describes as a way to "recharge" and find balance amidst the emotional burden and danger of her work.

3. Medical Interventions and Diagnoses in Basilan:

• Case Study 1: Sebaceous Cyst and Lipoma: A doctor explains and removes a sebaceous cyst (a soft tissue mass containing sebum) and a lipoma (an excess fat mass). The patients are reassured that these are benign tumors and not cancerous.
• Case Study 2: Hemangioma in an Infant: An 8-month-old baby presents with a mass on the upper eyelid, suspected to be a hemangioma. Due to the risk associated with anesthesia for such a young child and the location of the mass, the patient is referred to a larger hospital for surgery in a proper operating room.
• Case Study 3: Suspected Extrapulmonary TB: A patient presents with multiple large lymph nodes on the neck, suspected by Dr. Sampang to be extrapulmonary tuberculosis.
  • Explanation: Extrapulmonary TB can manifest in lymph nodes, the gut, or the stomach.
  • Data: TB cases are rising in the Philippines, with 160,000 new and relapsed cases in 2023, a nearly 40% increase from 2022.
  • Childhood TB: At least 43,000 children in the Philippines are currently diagnosed with TB.
  • Next Steps: Sputum samples will be collected and sent via drone to the Regional Health Unit (RHU) for GeneXpert testing to confirm the diagnosis of extrapulmonary TB, with results expected within an hour.

4. Drone Deployment and Success in Basilan:

• A new drone, couriered to Basilan just in time, is tested. This model is described as having better wind resistance (up to 20 km/h) and a higher ceiling (up to 4,000 m).
• The drone successfully delivers a sample, marking a culmination of six years of research and setbacks for Dr. Sampang.
• Key Outcome: The drone successfully returns, indicating a significant step forward in drone operability and reliability.
• Future Vision: Dr. Sampang aims to provide simplified drones to remote communities for autonomous sample submission to testing centers, a potential game-changer for TB detection and treatment in the Philippines.

5. TB Treatment and Compliance:

• A patient, Aby, tests positive for TB and will begin treatment funded by the government.
• Treatment Protocol: TB medications must be taken daily and consistently for six months to be effective and prevent the development of extremely drug-resistant organisms.
• Challenges: TB medications can have side effects, leading some patients to stop treatment. Education and monitoring are crucial.
• Compliance Strategy: Military personnel stationed in Basilan will assist in monitoring patient compliance with medication, using methods like telephone check-ins.

6. Government Support and Future Outlook:

• The Secretary of the Department of Technology attends a drone demonstration, indicating potential government support for integrating this technology into the health system.
• Drone Capabilities: The current drone has a range of 7 kilometers one way.
